text: The applicant, Dr. Samir S. Shah, is requesting five years of funding through the Mentored Research Scientist Development Award to enhance methodological skills required to conduct observational and interventional research on community-acquired pneumonia (CAP), a common and serious infection in children. The proposed training goals, including skills in advanced epidemiology and biostatistical methods, will allow the applicant to pursue methodologically sound, technically feasible, and innovative research approaches. The applicant's strong background of research and clinical training in pediatrics, infectious diseases, and epidemiology provides an excellent foundation for this work. The award will promote the development of Dr. Shah as an independent clinical investigator. The proposal will use an existing practice-based research network to conduct population-based cohort studies with the following specific aims: First, he will determine the incidence of and identify risk factors for adverse outcomes among children with CAP. Second, he will develop a simple and practical clinical prediction rule that would accurately predict the risk of a child with CAP developing an adverse clinical outcome. Third, the clinical prediction rule will be validated in an independent sample of ethnically and geographically diverse children, thus demonstrating its generalizability. Addressing the above specific aims will allow the identification of a high-risk population of children with CAP who may be suitable candidates for subsequent studies of therapeutic interventions (e.g., new antibiotics, immunomodulators) to improve clinical outcomes. The methods for case finding, study recruitment, data abstraction, clinical outcome validation, and patient follow-up established during this study will facilitate the conduct of future observational and interventional studies of children with CAP within this practice-based research network. The mentoring relationships, advanced formal training and education, and protected time afforded by the award will raise the sophistication, rigor, and quality of Dr. Shah's work and significantly facilitate his transition to a highly successful, independent, clinical investigator. Dr. Shah's research will improve our understanding of CAP and, from a public health perspective, will provide methods to risk stratify children with CAP and will establish a rational basis to target prevention efforts at those children at highest risk for developing CAP-related adverse clinical outcomes.

# Lesson: Prime Numbers
In this lesson, we will learn about prime numbers and how to determine if a number is prime.
## What are prime numbers?
Prime numbers are numbers that are only divisible by 1 and themselves. In other words, they cannot be divided evenly by any other number. For example, the first few prime numbers are 2, 3, 5, 7, 11, 13, 17, and so on.
## How do we determine if a number is prime?
To determine if a number is prime, we need to check if it is divisible by any number other than 1 and itself. We can do this by dividing the number by every number from 2 to the square root of the number. If none of these divisions result in a whole number, then the number is prime.
## Examples
Let's test some numbers to see if they are prime:
- 2 is prime because it is only divisible by 1 and 2.
- 4 is not prime because it is divisible by 2 without a remainder.
- 6 is not prime because it is divisible by 2 and 3 without a remainder.
- 8 is not prime because it is divisible by 2, 4, and itself.
- 10 is not prime because it is divisible by 2 and 5 without a remainder.
- 12 is not prime because it is divisible by 2, 3, 4, and itself.
## Practice Problems
1. Is the number 17 prime?
2. Is the number 21 prime?
3. Is the number 19 prime?
4. Is the number 11 prime?
5. Is the number 23 prime?
## Conclusion
Prime numbers are an important concept in mathematics. They have many applications, including cryptography and number theory. By learning how to determine if a number is prime, we can better understand the properties of numbers and how they relate to the world around us.

Q:

How can I find element indices in kdb?

How can i determine the index of first and last occurence of an element in a list in kdb. The list obviously has repeat values and is not sorted. The list contains only floats (prices) if that matters. I tried using bin and binr but its not giving the desired results.

A:

May I suggest an alternative (simpler? easier to read? more general?) solution:
q)list:1 2 3 2 4 2 5f
q)list=2.0
0101010b
q)where list=2.0
1 3 5
q)first where list=2.0
1
q)last where list=2.0
5

source: minipile

textbook:
Sure! Here's a lesson on finding element indices in kdb:
# Finding Element Indices in kdb
In kdb, you can use the `where` function to find the indices of elements in a list. This function returns a list of the same length as the original list, where each element is the index of the corresponding element in the original list.
## Section 1: Theoretical Concepts
The `where` function takes two arguments: the list to search and the value to look for. It returns a list of the same length as the original list, where each element is the index of the corresponding element in the original list.
## Section 2: Practical Examples
Here's an example of using `where` to find the indices of the first and last occurrences of an element in a list:
```
q)list:1 2 3 2 4 2 5f
q)list=2.0
0101010b
q)where index where list=2.0
1 3 5
q)first where index where list=2.0
1
q)last where index where list=2.0
5
```
In this example, we first convert the list to a binary representation using `bin`. Then we use `binr` to find the indices of the first and last occurrences of the value 2. Finally, we use `where` to find the indices of all occurrences of the value 2 in the list.
## Section 3: Self-Debating Discussions
One advantage of using `where` to find element indices is that it works even if the list is not sorted. However, if the list is already sorted, you could use the `sort` function to sort the list in ascending order, and then use the `range` function to find the indices of all elements in the sorted list.
## Glossary
- `where`: Returns a list of the same length as the original list, where each element is the index of the corresponding element in the original list.
- `bin`: Converts a list or vector to a binary representation.
- `binr`: Converts a binary representation to a list or vector.
- `sort`: Sorts a list or vector in ascending order.
- `range`: Returns a list of integers from 0 to n-1, where n is the length of the input list or vector.
## Conclusion
Finding element indices in kdb is a useful skill for working with lists and vectors. By using `where` and other functions, you can easily find the indices of elements in a list, even if the list is not sorted.

## Lesson: Introduction to Algebra
### Section 1: What is Algebra?
Algebra is a branch of mathematics that deals with the study of symbols, variables, and equations. It is used to represent real-world situations using mathematical models and abstractions. Algebra is divided into several branches, including linear algebra, abstract algebra, and algebraic geometry.
### Section 2: Why Study Algebra?
Studying algebra is important because it helps us understand and solve real-world problems. Algebra is used in many fields, including science, engineering, economics, and computer science. It is also used to solve everyday problems, such as calculating the cost of a purchase or determining the distance between two points on a map.
### Section 3: How Does Algebra Work?
In algebra, we use variables to represent unknown values. These variables can take on any value, and their values are determined by the equation they are part of. For example, if we have the equation x + 2 = 5, we can solve for x by substituting 3 for x, which gives us 3 + 2 = 5, or 5 = 5.
### Section 4: Practical Examples
Let's consider an example from the real world. Suppose you have $1000 in your bank account and you want to buy a new car that costs $20,000. You have already saved $5000, so you need to borrow the remaining $15,000. To figure out how much interest you will pay over the life of the loan, you need to calculate the monthly interest rate. Using algebra, we can set up an equation to solve for the monthly interest rate:
M = P * r * (1 + r)^n / ((1 + r)^n - 1)
Where:
- M is the monthly payment
- P is the principal (the amount borrowed)
- r is the monthly interest rate (expressed as a decimal)
- n is the number of months over which the loan is repaid
By solving for r, we can find the monthly interest rate.
### Section 5: Conclusion
Algebra is a powerful tool that allows us to model and solve real-world problems. By studying algebra, we can develop critical thinking skills and learn to analyze and solve complex problems. Whether you are a student, a professional, or simply someone who enjoys solving puzzles, algebra is a valuable skill to have.

Let's consider an example of using jewelry endings in a project. Suppose you are making a bracelet out of leather. You could use flat crimp endings to secure the leather strings in place. Alternatively, if you are making a necklace out of wax, you could use glue-on round endings to attach the wax beads.

Section 4: Self-Debating Discussions
What are some factors to consider when choosing jewelry endings for your projects? One important factor is the material of the ending. Silver endings are a popular choice because they are durable and look elegant. Another factor to consider is the type of string or material you will be using. If you are working with wax or leather strings, you will need to choose endings that are suitable for those materials.

Conclusion:
In this lesson, we have learned about the different types of jewelry endings, their materials, and their uses. We have also considered practical examples of how to use endings in projects and engaged in self-debating discussions about factors to consider when choosing endings. By applying these concepts, you will be able to confidently select the perfect endings for your jewelry designs.

Some of us who sincerely treasure the scientific fact and scientific theory of evolution have brought on some of our own problems with our choice of nomenclature. For instance, sometimes “random mutations” gets uncoupled from natural selection, leading some to believe that it is the randomness of the process that is the be-all and end-all of evolution. Consider also Francis Crick’s description of the associations of amino acids with their three base codons as a “frozen accident.”

Creationists, ignoring these (legitimate) scientific and scientific/poetic usages, have jumped all over the terms such as “random” and “accident” to characterize scientific evolutionary theory in the following warped way: “All life forms just suddenly spring into existence as accidents.” Though I am aware that sophisticated creationists would embellish this attack, this characterization is certainly the straw man put forth by most of the people out there who tremble at the thought that human beings are (gad!) animals.

It recently occurred to me that, perhaps, creationists’ willingness to assume that evolutionists are claiming that complex life forms “just happen” might be another symptom of “innumeracy.” It might be that they don’t understand how incredibly rare it is that biological “accidents” survive and reproduce. In his bestseller, Innumeracy: Mathematical Illiteracy and Its Consequences (1988), John Paulos introduced the term “innumeracy” to refer to “an inability to deal comfortably with the fundamental notions of number and chance.” Paulos bemoaned that innumeracy “plagues far too many otherwise knowledgeable citizens.”

How is Innumeracy related to Creationism? It seems to me that creationists believe that evolutionary theory holds that after a relatively few accidents, complex life forms spring into existence. This just couldn’t be, creationists argue. That characterization doesn’t work for me either. That is why I have termed it a straw man argument.

Perhaps skeptical creationists (they are selectively skeptical) would even refer to an illustration used by Daniel Dennett in his 1995 work, Darwin’s Dangerous Idea. Dennett stated that “the DNA in your body, unsnarled and linked would stretched to the sun and back several-10 or 100-times.” A work of such immense complexity just couldn’t spring into existence by any simple accident, right?

But what if creationists better understood the enormous number of mutations that amounted to nothing compared to those that amounted to something? What if they understood that we’re not talking about mere accidents. We’re talking about unimaginably unlikely accidents that are equally rare and precious. This idea reminded me of another illustration used by Daniel Dennett, also presented in Darwin’s Dangerous Idea.

Borrowing from a short story by Jorge Luis Borges, Dennett (on page 108) asks us to imagine a huge library full of all possible 500-page long books, each page with 2000 characters. Each space on each page is either blank or has a character, each character being one of 100 standard upper and lowercase English/European characters. Dennett does the finite math for us, calculating that such a library would contain 1001,000,000 books. In comparison, there are only 10040 particles in the observable universe. Therefore, Dennett’s “Library of Babel “is not remotely a physically possible object.” He asked us to keep in mind that this is not a library of all possible books, since his library will not contain Greek, Russian, Chinese, Japanese or Arabic, characters, to name a few. Dennett uses this Library of Babel illustration as “an anchoring vision for helping to answer very difficult questions about the scope of biological possibility.”

Consider, now, the “library of Mendel” which is composed of descriptions of genomes is “just a proper part of the Library of Babel.” Each of the 500-page permutations of the four letters (the nucleotides that composed the letters of the DNA alphabet) are already in the Library of Babel. Dennett warns that genomes are much longer than ordinary books, however. Dennett writes that the information of the human genome would take up approximately 3000 of the 500-page volumes of Dennett’s library.

How big is Dennett’s Library of Babel? Dennett warns that all of our metaphors for bigness (e.g., a drop in the ocean) fall comically short. Not even an actual astronomical quantity (such as the number of elementary particles in the universe) “is even visible against the backdrop of these huge but finite numbers.”

Somewhere in this vast library you can find a perfect copy of Moby Dick (and lots of imperfect copies—most of those so imperfect as to be unreadable). As Dennett plainly points out, though, most of books in this Library would consist of complete “typographical gibberish. “No rules of spelling or grammar, to say nothing of sense, prohibit the inclusion of a volume.” When you compare the universe of meaningful books to the size of Dennett’s library you can see that almost everything out there is gibberish. Almost everything in Dennett’s library is a non-useful accident. The useful accidents are almost impossible to find.

Similarly, most possible DNA sequences, the vast majority actually, “are surely gibberish, recipes for nothing living at all. That is what Dawkins means, of course, when he says that there are “many more ways of being dead (or not alive) than ways of being alive.”

Therefore, it is really (really) unlikely that nature will put together new biological accidents that live and reproduce. I suspect that creationists assume that evolutionists claim that biological accidents resulting in new life forms are about as likely as automobile accidents; that they happen regularly. This makes no sense to them. If I understood evolution in this way, it wouldn’t make any sense to me either. Dennett’s Library of Babel helps to dispel this statistical misconception.

Not all accidents are the same. Some are extremely unlikely. So unlikely that you should write them off as “simply not going to happen.” Unless you have 4.5 billion years to work with and quadrillions of little accident generators (microorganisms and, eventually, organisms) working overtime. But guess what? We do have 4.5 billion years and a planet full of accidents waiting to happen.

Then again, I suppose that creationists, if they understood the numbers better, would argue that it proves that the creation of new life forms is so utterly improbable that “God” must’ve done it. This is but another version of the design argument. Innumeracy is part of this common misunderstanding too. This problem is also caused, I suspect, by the fact that most creationists don’t recognize the incremental non-totally random nature of the very rare successful mutation “accidents” that do occur. You don’t start from ground zero and then shoot up a sheer cliff into a fully formed complex life form. A good place for exploring that incremental changes drive evolution is Richard Dawkins’ Climbing Mount Improbable.

Lesson: The Core Value of Evolutionary Theory

Introduction:
Evolutionary theory is a fundamental concept in biology that explains how species change over time. It provides a framework for understanding the relationships between different organisms and their environments. However, some people have misconceptions about what evolutionary theory actually entails. In this lesson, we will explore the core value of evolutionary theory and dispel common myths about the process.

Section 1: Understanding Evolutionary Theory

Topic 1: What is Evolutionary Theory?
Evolutionary theory is the scientific explanation for how species change over time. It is based on the idea that populations of organisms change through the process of natural selection. This means that certain traits become more or less common in a population depending on whether they help the organism survive and reproduce.

Topic 2: Misconceptions about Evolutionary Theory
Some people think that evolutionary theory states that organisms just randomly change over time without any direction or purpose. However, this is not true. Evolutionary theory is based on the idea that there is a direction to evolution, and that organisms are constantly adapting to their environment in order to survive and reproduce.

Topic 3: The Role of Random Mutations
Random mutations are an important part of evolutionary theory. They provide the raw material for natural selection to act upon. Without random mutations, there would be no variation in a population for natural selection to work with. However, random mutations do not mean that evolution is entirely random. Instead, they provide the basis for the directional change that occurs through natural selection.

Section 2: Applying Evolutionary Theory to Real-World Scenarios

Topic 1: Examples of Evolution in Action
Evolutionary theory can be observed in many different organisms and environments. For example, antibiotic resistance in bacteria is a result of natural selection. When exposed to antibiotics, some bacteria are better able to survive and reproduce than others. Over time, the population of bacteria becomes more resistant to antibiotics.

Topic 2: The Importance of Evolutionary Theory
Evolutionary theory has many practical applications. For example, it can be used to understand the spread of diseases. By studying how diseases evolve over time, scientists can develop better treatments and vaccines. Evolutionary theory can also be used to understand the relationships between different species and their environments. This knowledge can help conservationists protect endangered species and their habitats.

Section 3: Critical Thinking Questions

Topic 1: How does natural selection lead to evolutionary change?
Natural selection is the process by which certain traits become more or less common in a population over time. If a trait helps an organism survive and reproduce, it will be passed on to future generations. Over many generations, these advantageous traits become more common in the population, leading to evolutionary change.

Topic 2: How do random mutations contribute to evolution?
Random mutations provide the raw material for natural selection to act upon. Without variation in a population, there would be nothing for natural selection to work with. Random mutations introduce new traits into a population, which can then be selected for or against through natural selection.

Conclusion:
In conclusion, the core value of evolutionary theory is that it provides a scientific explanation for how species change over time. It is based on the idea that populations of organisms change through the process of natural selection, which is driven by both random mutations and directional change. By understanding evolutionary theory, we can better appreciate the relationships between different species and their environments, and use this knowledge to protect and conserve endangered species.

Glossary:
- Evolutionary theory: A scientific explanation for how species change over time, based on the idea that populations of organisms change through the process of natural selection.
- Natural selection: The process by which certain traits become more or less common in a population over time, depending on whether they help the organism survive and reproduce.
- Random mutations: Changes in an organism's DNA that occur randomly and provide the raw material for natural selection to act upon.
- Directional change: The idea that evolution is not entirely random, but rather has a direction or purpose.
- Endangered species: Species that are at risk of becoming extinct due to habitat destruction, hunting, or other factors.

Gene expression in cytokinin-and light-mediated plastogenesis of Cucurbita cotyledons: ribulose-1,5-bisphosphate carboxylase/oxygenase.
The effects of a cytokinin (N(6)-benzyladenine, BA) and light on plastogenesis have been studied in detached Cucurbita cotyledons using the key enzyme of photosynthetic CO2 fixation, ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCase), as an example of a coordinated program of plastid and nucleo-cytoplasmic gene expression. Treatment of etiolated cotyledons with either BA in darkness or in light or light alone results in a marked and correlated stimulation of enzyme activity, quantity and biosynthesis (in-vivo [(14)C]leucine incorporation into immunoprecipitated enzyme protein), indicating an increase of de-novo synthesis under the influence of the two effectors. Cell-free translation of non-polyadenylated (poly(A)(-))RNA in an Escherichia coli system and total RNA in a wheat-germ system likewise demonstrate a light and hormone-dependent increase in the amounts of translatable mRNAs for the large (LS) and small subunits (SS) of RuBPCase (among other polypeptides). Hybridisation of poly(A)(-)RNA with a nick-translated LS gene of spinach RuBPCase reveals also two-to three-fold BA-or light-induced enhancement of LS mRNA content. Indications for stimulation of SS mRNA transcription are derived from inhibitor experiments with cordycepin. We conclude that the observed stimulation of de-novo RuBPCase synthesis by cytokinin and by light can be referred to the level of mRNA transcription, but it remains open whether this is a primary action. Furthermore, our results indicate that the coaction of the two exogenous factors is additive at different steps of RuBPCase formation, indicating independent actions in the causal chain between effector-signal transduction and RuBPCase gene expression.

Lesson Title: Gene Expression in Cytokinin- and Light-Mediated Plastogenesis of Cucurbita Cotyledons

Introduction:
Gene expression is the process by which information from a gene is used to synthesize functional gene products. In plants, gene expression plays a crucial role in growth and development. This lesson will focus on the effects of cytokinin and light on plastogenesis in Cucurbita cotyledons using ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCase) as an example.

Section 1: Background Information
- Gene expression is the process by which information from a gene is used to synthesize functional gene products.
- Plastogenesis is the process by which plastids, such as chloroplasts, are formed in plant cells.
- Cytokinins are plant hormones that regulate cell division and differentiation.
- Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCase) is the key enzyme of photosynthetic CO2 fixation.

Section 2: Experimental Procedure
- Detach cucumber cotyledons and place them in a dark or light environment.
- Treat the cotyledons with either N(6)-benzyladenine (BA) or a combination of BA and light.
- Measure the activity, quantity, and biosynthesis of RuBPCase using in-vivo [(14)C]leucine incorporation into immunoprecipitated enzyme protein.
- Perform cell-free translation of non-polyadenylated (poly(A)(-))RNA in an Escherichia coli system and total RNA in a wheat-germ system to demonstrate light and hormone-dependent increases in gene expression.

Section 3: Results and Conclusion
- The results show that treatment of etiolated cotyledons with either BA in darkness or in light or light alone results in a marked and correlated stimulation of enzyme activity, quantity, and biosynthesis, indicating an increase of de-novo synthesis under the influence of the two effectors.
- Cell-free translation of non-polyadenylated (poly(A)(-))RNA in an Escherichia coli system and total RNA in a wheat-germ system likewise demonstrate a light and hormone-dependent increase in gene expression.
- These results suggest that cytokinin and light can regulate gene expression in plants, leading to changes in growth and development.

Glossary:
- Gene expression: the process by which information from a gene is used to synthesize functional gene products.
- Plastogenesis: the process by which plastids, such as chloroplasts, are formed in plant cells.
- Cytokinin: a plant hormone that regulates cell division and differentiation.
- Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCase): the key enzyme of photosynthetic CO2 fixation.

Conclusion:
This lesson has demonstrated the importance of gene expression in regulating growth and development in plants. By understanding how factors such as cytokinin and light can affect gene expression, scientists can better understand how to manipulate plant growth and improve crop yields. Students should be encouraged to explore other examples of gene expression in plants and other organisms to gain a deeper understanding of the role of gene expression in biology.

Title: Understanding Orbital Determination and its Applications

**Introduction**

Orbital Determination is the process of calculating the position of an object in space relative to other objects or points of reference. It is an essential tool for understanding and predicting the behavior of celestial bodies. In this lesson, we will explore the principles behind Orbital Determination, its applications, and how it has evolved over time.

**Section 1: Understanding Orbital Determination**

Orbital Determination is the process of calculating the position of an object in space relative to other objects or points of reference. This is done using mathematical models that take into account the gravitational pull of other objects, the speed of the object, and other factors that affect its motion.

The most common model used for Orbital Determination is the two-body problem, which assumes that only two bodies interact with each other. However, more complex models are used when dealing with multiple objects or when taking into account other factors such as atmospheric drag or solar radiation pressure.

**Section 2: Applications of Orbital Determination**

Orbital Determination has many practical applications in fields such as astronomy, navigation, and aerospace engineering. Here are some examples:

- Astronomy: Orbital Determination is used to track the movement of celestial bodies such as planets, moons, and asteroids. This information helps astronomers understand the behavior of these objects and predict their future positions.

- Navigation: Orbital Determination is used to calculate the trajectory of satellites and other spacecraft. This information is crucial for planning space missions and ensuring that spacecraft stay on course.

- Aerospace Engineering: Orbital Determination is used to design and build spacecraft that can operate in space. Engineers use this information to design spacecraft that can withstand the harsh conditions of space and operate efficiently.

**Section 3: Evolution of Orbital Determination**

Orbital Determination has come a long way since its beginnings in ancient times. Here are some key milestones in its evolution:

- Ancient Times: Early astronomers used simple observations to calculate the positions of celestial bodies.

- 17th Century: Johannes Kepler developed the laws of planetary motion, which provided a mathematical framework for Orbital Determination.

- 18th Century: Isaac Newton developed the laws of gravity, which were crucial for understanding the motion of celestial bodies.

- 20th Century: The development of computers and advanced mathematical models allowed for more accurate Orbital Determinations.

**Conclusion**

Orbital Determination is a fundamental tool for understanding and predicting the behavior of celestial bodies. Its applications span across many fields, including astronomy, navigation, and aerospace engineering. As technology advances, we can expect even more accurate and sophisticated Orbital Determinations that will help us better understand our universe.

## Lesson: Language and Thought
### Introduction
Language is a fundamental aspect of human life. It is a tool for communication, expression, and understanding. However, there has been a longstanding debate on whether language shapes thought or thought shapes language. This lesson will explore the Whorfian perspectives on this issue and provide an overview of the history and development of theories, controversies, and issues surrounding the Sapir-Whorf hypothesis and theory.
### Section 1: The Sapir-Whorf Hypothesis
The Sapir-Whorf hypothesis, also known as linguistic relativity, is a theory that suggests that the structure and vocabulary of a language influence the way speakers think and perceive the world. This hypothesis was first proposed by Edward Sapir and Benjamin Whorf in the early 20th century. According to this theory, the relationship between language and thought is not one-way; rather, it is a two-way street.
### Section 2: The Whorfian Perspectives
Whorf's views on language and thought were more radical than Sapir's. He argued that language is not just a tool for expressing thoughts but also a tool for shaping them. According to Whorf, the structure and vocabulary of a language determine how speakers perceive and understand the world. For example, he argued that Inuit people, who have multiple words for snow, are more likely to perceive snow as a fundamental part of their environment.
### Section 3: Controversies and Issues
The Sapir-Whorf hypothesis has been the subject of much debate and controversy. Some linguists argue that language is a tool for expressing thoughts, not shaping them. Others argue that the relationship between language and thought is complex and multifaceted. There is evidence to suggest that language can influence perception and cognition, but it is not clear to what extent.
### Conclusion
In conclusion, the relationship between language and thought is a complex and fascinating area of study. While there is no consensus on the Sapir-Whorf hypothesis, it is clear that language plays an important role in shaping our perceptions and understanding of the world. By studying the history and development of theories, controversies, and issues surrounding this topic, we can gain a deeper understanding of the power and limitations of language.

Neural networks-based modeling applied to a process of heavy metals removal from wastewaters.
This article approaches the problem of environment pollution with heavy metals from disposal of industrial wastewaters, namely removal of these metals by means of biosorbents, particularly with Romanian peat (from Poiana Stampei). The study is carried out by simulation using feed-forward and modular neural networks with one or two hidden layers, pursuing the influence of certain operating parameters (metal nature, sorbent dose, pH, temperature, initial concentration of metal ion, contact time) on the amount of metal ions retained on the unit mass of sorbent. In neural network modeling, a consistent data set was used, including five metals: lead, mercury, cadmium, nickel and cobalt, the quantification of the metal nature being done by its electronegativity. Even if based on successive trials, the method of designing neural models was systematically conducted, recording and comparing the errors obtained with different types of neural networks, having various numbers of hidden layers and neurons, number of training epochs, or using various learning methods. The errors with values under 5% make clear the efficiency of the applied method.

Lesson: Introduction to Neural Networks in Modeling Heavy Metals Removal from Wastewaters

**Overview:** In this lesson, we will learn about Neural Networks and their application in modeling the removal of heavy metals from wastewaters. We will cover the basics of Neural Networks, their architecture, and how they can be used to solve complex problems. By the end of this lesson, you will be able to understand the fundamentals of Neural Networks and their role in environmental science.

**Objectives:**

1. Understand the basic concepts of Neural Networks and their architecture.
2. Learn how Neural Networks can be used to model the removal of heavy metals from wastewaters.
3. Apply Neural Networks to solve a real-world problem related to environmental science.

**Section 1: Introduction to Neural Networks**

**Topic 1: What are Neural Networks?**

Neural Networks are a type of machine learning algorithm that is inspired by the structure and function of the human brain. They are composed of interconnected nodes that work together to solve complex problems. Neural Networks can be used to model and predict a wide range of phenomena, including the behavior of chemical systems and the removal of heavy metals from wastewaters.

**Topic 2: How do Neural Networks work?**

Neural Networks consist of an input layer, one or more hidden layers, and an output layer. The input layer receives the input data, which is then processed by the hidden layers. Each node in the hidden layers represents a feature of the input data, and the weights of the connections between the nodes determine the importance of each feature. The output layer produces the final prediction, which is then compared to the actual output to evaluate the performance of the Neural Network.

**Topic 3: Types of Neural Networks**

There are several types of Neural Networks, including Feedforward Neural Networks, Recurrent Neural Networks, and Modular Neural Networks. Feedforward Neural Networks process information sequentially, while Recurrent Neural Networks can process information in parallel and maintain a state that changes over time. Modular Neural Networks are a combination of Feedforward and Recurrent Neural Networks and can be used for both sequential and parallel processing.

**Section 2: Applying Neural Networks to Environmental Science**

**Topic 1: Problem Statement**

The removal of heavy metals from wastewaters is a critical issue in environmental science. Heavy metals such as lead, mercury, cadmium, nickel, and cobalt can cause severe health problems and damage to the environment. In this lesson, we will use Neural Networks to model the removal of heavy metals from wastewaters using Romanian peat as a biosorbent.

**Topic 2: Data Set and Preprocessing**

To train a Neural Network, we need a large dataset of input-output pairs. In this case, we will use a dataset that includes five metals: lead, mercury, cadmium, nickel, and cobalt. The quantification of the metal nature will be done by its electronegativity. We will also need to preprocess the data by normalizing the input features and scaling the output values.

**Topic 3: Model Architecture and Training**

We will use a Modular Neural Network with one or two hidden layers to model the removal of heavy metals from wastewaters. The architecture of the Neural Network will depend on the complexity of the problem and the size of the dataset. We will train the Neural Network using backpropagation and gradient descent to minimize the error between the predicted output and the actual output.

**Section 3: Practical Examples and Discussion**

**Topic 1: Predicting the Amount of Metal Ions Retained**

Using the trained Neural Network, we can predict the amount of metal ions retained on the unit mass of sorbent for different operating parameters such as metal nature, sorbent dose, pH, temperature, initial concentration of metal ion, and contact time. For example, if we know the initial concentration of lead ions in the wastewater and the amount of Romanian peat used, we can use the Neural Network to predict the final concentration of lead ions after treatment.

**Topic 2: Self-Debating Discussions**

Neural Networks are powerful tools for solving complex problems, but they also have limitations. One limitation of Neural Networks is their lack of interpretability. It can be difficult to understand how the Neural Network arrived at its predictions, making it hard to identify the most important features and their relationships. To overcome this limitation, we can use techniques such as feature importance analysis and visualization of the Neural Network's internal representations.

**Conclusion**

In this lesson, we have learned about Neural Networks and their application in modeling the removal of heavy metals from wastewaters. We have covered the basics of Neural Networks, their architecture, and how they can be used to solve complex problems. By applying Neural Networks to a real-world problem in environmental science, we have demonstrated the power of these algorithms and their potential for solving other challenges in the field.

Once it became clear that the 2016 general election matchup would be between Donald Trump and Hillary Clinton, one of the big unanswered questions was how the Democrats and the Clinton campaign would approach their politically exotic adversary. And it was looking a little dodgy there for a bit. Early reports indicated that the Clinton campaign was going to attack Trump as a heartless businessman whose ruthless tactics had screwed over normal people – an attack that worked perfectly well against Mitt Romney but risked feeding into Trump’s self-styled image as a cutthroat hard-ass. Then came the nicknames: “Dangerous Donald,” “loose cannon,” “risky,” etc. It seemed like Hillary and the DNC were determined to attack Trump in ways that also helped validate his shtick about being an outsider who will go to Washington and break things.

But it looks like Hillary and her team have figured out how to effectively hit Trump. Clinton gave what was billed as a major foreign policy speech yesterday, but the real purpose of it was to get Hillary in front of the cameras so she could mock the hell out of her opponent for 40 minutes. She was pretty merciless in her treatment of Trump, and it made for some of the best politicking we’ve seen from Clinton this entire race.

What made it so effective is that Hillary pegged Trump as petty, ignorant, and weak. She called Trump’s foreign policy ideas “dangerously incoherent” and “a series of bizarre rants, personal feuds, and outright lies.” She poked fun at his obvious lack of basic knowledge about foreign affairs. “He says he has foreign policy experience because he ran the Miss Universe pageant in Russia,” Clinton said, letting the absurdity of that real Trump statement do her work for her. “Donald Trump doesn’t know the first thing about Iran or its nuclear program,” she said. “Ask him. It’ll become very clear very quickly.”

And she called Trump “dangerous,” but more importantly she explained why Trump is dangerous. “This is not someone who should ever have the nuclear codes,” Hillary said, “because it’s not hard to imagine Donald Trump leading us into a war because someone got under his very thin skin.” This is the right way to frame the argument. Trump embraces the “dangerous” designation to a certain degree because he wants people to see him as someone who will shake the existing order. We saw this last week after President Obama said that world leaders were “rattled” by Trump’s nomination. “When you rattle someone, that's good,” Trump said in response. “If they're rattled in a friendly way, that's a good thing.”

What Clinton did was point out that the danger Trump poses is rooted in his own pettiness and instability. “I will leave it to the psychiatrists to explain his affection for tyrants,” she said at one point, making a fairly pointed suggestion about his mental competence. She treated her rival with thinly veiled contempt and spent the majority of the speech portraying him as incompetent and, more importantly, weak and impotent. “We all know the tools Donald Trump brings to the table: bragging, mocking, composing nasty tweets. I’m willing to be he’s writing a few right now.” That’s the kind of stuff that drives Trump nuts, and the more time Clinton spends needling him as a buffoonish cartoon character, the better.

Where Clinton’s speech was less impressive was in its treatment of the specifics of foreign policy. Most of what she had to say in terms of policy goals dealt with terrorism generally (“the threat is real and urgent,” she said, referring to the San Bernardino shootings) and the Islamic State specifically. She called for stepped up airstrikes on ISIS targets and increased support for “Arab and Kurdish forces on the ground” alongside diplomatic efforts to end the Syrian civil war and ameliorate the sectarian rifts hobbling the Iraqi government (she didn’t say anything about a no-fly zone over Syria, which she has supported previously). There was no mention of the atrocious humanitarian crisis caused by the ongoing U.S.-backed war in Yemen, nor did she say anything about the chaos in Libya, which arose as a result of the U.S.-led intervention that she herself championed as secretary of state. It’s well and good to make the case that Trump has no business commanding the U.S. military, but she’s still going to have to make an affirmative case for why she should be entrusted with the job.

Lesson: Critical Thinking and Debate

Introduction:
Critical thinking and debate are essential skills for success in life. They help us analyze information, make informed decisions, and communicate effectively. In this lesson, we will learn how to think critically and engage in debates by analyzing a political article.

Section 1: Introduction to Critical Thinking
Critical thinking is the process of analyzing information to make informed judgments. It involves questioning assumptions, evaluating evidence, and considering alternative perspectives.

Section 2: Analyzing the Article
Let's read the article carefully and identify the main points.

- The article discusses the 2016 US presidential election between Donald Trump and Hillary Clinton.
- The Clinton campaign initially planned to attack Trump as a heartless businessman, but this strategy risked validating Trump's self-styled image as a cutthroat hard-ass.
- The Clinton campaign eventually figured out how to effectively hit Trump by mocking him during a major foreign policy speech.

Section 3: Debate Questions
1. What strategies did the Clinton campaign use to attack Trump?
2. How did Hillary Clinton effectively hit Trump during her speech?
3. What risks did the Clinton campaign face when attacking Trump as a heartless businessman?
4. How does the article demonstrate critical thinking?

Section 4: Practice Debate
Let's imagine we are having a debate about the effectiveness of the Clinton campaign's strategies. Here are some questions to consider:

- Pro: The Clinton campaign successfully attacked Trump by highlighting his lack of foreign policy experience and his tendency to make reckless decisions.
- Con: The Clinton campaign's initial strategy of attacking Trump as a heartless businessman risked alienating voters who support business-friendly policies.

Section 5: Conclusion
In this lesson, we learned about critical thinking and debating by analyzing a political article. We identified the main points of the article, asked questions to stimulate discussion, and practiced debating with hypothetical arguments. By developing our critical thinking and debate skills, we can become more effective communicators and decision-makers.


text: Yet another system of time-keeping has been in effect since 1884. By international agreement, the transit telescope at the Old Royal Observatory in Greenwich, England, defines the Prime Meridian for the planet Earth. At the same time, the Old Royal Observatory was also given the distinction of being the standard reference for time.. Most announcements of international events, such as astronomical happenings or radio broadcasts, are given in terms of Greenwich Mean Time, now called coordinated universal time, or UCT. To determine when an event will take place in your local time zone all you need to do is add or subtract the appropriate number of hours from the UCT listing.. Time zones west of Greenwich lag UCT, while those east lead GMT. Los Angles, for example, is eight zones behind Greenwich, so when it is starting time (9:00 am) in LA, it is already quitting time (5:00 pm) in Greenwich. The Universal Clock contains one memory address that stores the difference between UCT and your local time.

textbook:
Lesson: Introduction to Time Zones

## Section 1: Theoretical Concepts
Time zones are regions of the Earth that have the same standard time, usually separated by one hour. There are 24 time zones around the world, each representing 15 degrees of longitude. The prime meridian, which passes through Greenwich, England, serves as the reference point for time zones.

## Section 2: Questions and Answers
**Question:** Why do we use time zones?
**Answer:** Time zones help us organize our daily activities and keep track of events happening around the world. They make it easier to coordinate schedules and plan travel.

**Question:** How many time zones are there?
**Answer:** There are 24 time zones around the world, each representing 15 degrees of longitude.

**Question:** What is the reference point for time zones?
**Answer:** The prime meridian, which passes through Greenwich, England, serves as the reference point for time zones.

## Section 3: Definitions and Examples
**Definition:** A time zone is a region of the Earth that has the same standard time.

**Example:** New York City is in the Eastern Standard Time zone, which is five hours behind Coordinated Universal Time (UTC-5).

## Section 4: Practical Examples Using Mathematical Abstractions and Real-World Scenarios
**Practical Example:** If it is 9:00 am in Los Angeles, which is eight hours behind Greenwich Mean Time, what time is it in London, which is two hours ahead of Greenwich Mean Time?

**Solution:** To find the time in London, we need to add eight hours to 9:00 am in Los Angeles. So, 9:00 am + 8 hours = 5:00 pm in London.

**Real-World Scenario:** If a plane departs from New York City at 7:00 pm Eastern Standard Time and arrives in London at 10:00 am the next day, what time zone is London in?

**Solution:** Since London is two hours ahead of Greenwich Mean Time, it is three hours ahead of New York City. Therefore, the plane would depart New York City at 7:00 pm EST and arrive in London at 10:00 pm GMT.

## Glossary
- Time zone: A region of the Earth that has the same standard time.
- Prime meridian: A line of longitude that passes through Greenwich, England, and serves as the reference point for time zones.
- Coordinated Universal Time (UTC): The standard time common to all countries.
- Greenwich Mean Time (GMT): The mean solar time at the prime meridian of Greenwich, used as the basis for UTC.

## Conclusion
In this lesson, we learned about time zones and their importance in organizing our daily activities. We also explored practical examples using mathematical abstractions and real-world scenarios to understand how time zones work. By understanding the basics of time zones, we can better navigate across different time zones and stay connected with people around the world.

Auditory, visual, tactile, olfactory, and bodily hallucinations in patients with obsessive-compulsive disorder.
Although much attention has been paid to patients who lack insight into their obsessional beliefs, less importance has been given to individuals with obsessive-compulsive disorder (OCD) who display perceptual disturbances typically found in psychotic disorders, including schizophrenia, schizoaffective disorders, or mood disorders with psychotic features. We would like to call the attention to a phenomenon that has been neglected in the psychiatric literature: the occurrence of hallucinations and related phenomena in patients with OCD. In this case report, we describe five clinical vignettes of patients with OCD with hallucinations in several different sensory modalities, including the auditory, the visual, the tactile, the olfactory, and the cenesthetic ones. Further psychopathological research should clarify the clinical significance of hallucinations among patients with OCD.
