While communication with the audience or group of people, most of us use gestures to drive our point, sometimes our gestures speak louder than our words. Experts believe that your stance and gestures are arguably more important than what you actually say.

According to Daily Mail, with right kind of gestures, you can captivate your audience because your gestures enhance your confidence. Here we look at the five gestures that will make you likeable and credible at the same time.

1. Gesturing towards the audience

Eye contact is something which is very important while addressing the gathering. This kind of gesture helps engage your audience effectively. Gesturing towards audience or gathering increases their attention and also helps them connect with you immediately. What is important is that you must look around at the audience in order to make eye contact. Eye contact not only ensure audience involvement but also gives you an opportunity to ask for their feedback that leads to interaction. Pointing towards the audience shows your confidence.

2. Putting hand on Heart

Touching your heart while addressing a gathering shows your sincerity and intense conviction. This kind of gesture makes your audience believe you and engage them with what you are saying. Pairing these gestures with a smile or an animated facial expression allows the audience to connect with you emotionally and warmly. You can see social activist and Nobel Prize winner Malala Yousafzai often touching her heart.

3. Raising hands above waist level

This kind of gesture allows you to better direct and signal the points you are making. It also shows an open personality and a willingness to engage with the audience. Strong gestures can also aid in keeping the audience's attention focused on the story being told or points being made.

4. Leaning in towards the audience

Leaning in towards the audience with your head forward shows your eagerness to relay your information to the audience and your level of comfort while speaking with them. Pushing your head forward also shows that you have lots of ideas and thoughts. By raising the head or shoulders, help you emphasise the points you are making. Former US president Barack Obama is a perfect example of this particular gesture.

5. Maintaining a symmetrical stance

It is very important to stay natural and use the space available while speaking to an audience. This gesture shows your comfort level and also your confidence. The audience is more likely to absorb information from someone they view as balanced and confident.

Preferences Regarding and Communication About End-of-Life Care Among Older Iranian-American Adults.
Using a cross-sectional study, this article addresses end-of-life (EOL) care for older Iranian-American adults. The purposes are twofold: (a) to explore participants' preferences for home or hospital care in the event they face EOL conditions and (b) to learn how participants prefer to communicate these preferences. Results showed that about half of the 130 participants had communicated their EOL care preferences through written documents and/or verbal discussions. A set of factors predicted the preferences (χ2(9) = 17.42, p < .042) and communications (χ2(9) = 19.54, p = .021). Regression models indicated that higher scores of social support (p = .013) and greater numbers of cohabitants (p = .021) were associated with a preference for home care, and experience of a loved one's death was associated with participants being willing to communicate their preferences for type of care (p = .015). This study can bridge the gap between culturally diverse older adults' preferences and types of EOL care they ultimately receive.

textbook:
Lesson: Introduction to End-of-Life Care Preferences and Communication Among Older Adults

Overview:
In this lesson, we will explore the preferences and communication patterns related to end-of-life (EOL) care among older adults. We will discuss the importance of understanding these preferences and how they can impact the quality of care received by individuals nearing the end of their lives.

Objectives:
By the end of this lesson, students will be able to:

1. Define end-of-life care and its importance in healthcare.
2. Identify factors that influence EOL care preferences among older adults.
3. Explain the benefits of communicating EOL care preferences to healthcare providers.
4. Describe strategies for initiating conversations about EOL care preferences with healthcare providers.

Section 1: Introduction to End-of-Life Care

End-of-life care refers to the medical and supportive care provided to individuals who are nearing the end of their lives. This type of care is designed to provide comfort and relief from symptoms while supporting the patient's dignity and quality of life. EOL care is an important part of healthcare, as it helps individuals live their final days with as much comfort and peace as possible.

Section 2: Factors Influencing EOL Care Preferences

Several factors can influence an individual's preferences for EOL care. These factors include:

1. Cultural and religious beliefs: Some cultures and religions have specific beliefs about death and dying, which can impact an individual's preferences for EOL care.
2. Personal values: An individual's personal values can play a significant role in shaping their preferences for EOL care. For example, some individuals may value autonomy and control over their care, while others may prioritize comfort and relief from symptoms.
3. Health status: An individual's current health status can impact their preferences for EOL care. For example, individuals with advanced illnesses may prefer aggressive treatment, while those with less severe conditions may prefer a more conservative approach.
4. Social support: Having a support system in place can impact an individual's preferences for EOL care. Those with strong social support may be more likely to choose home-based care, while those without support may prefer institutional care.

Section 3: Communicating EOL Care Preferences to Healthcare Providers

Communicating EOL care preferences to healthcare providers is important for several reasons:

1. It ensures that the individual's wishes are respected and honored, promoting a sense of control and autonomy.
2. It helps healthcare providers make informed decisions about the individual's care, ensuring that they receive the most appropriate and effective treatment options.
3. It allows for open and honest communication between the individual and their healthcare team, fostering trust and collaboration.

Section 4: Strategies for Initiating Conversations About EOL Care Preferences

Initiating conversations about EOL care preferences can be challenging, but there are several strategies that can help:

1. Start early: It's never too early to start talking about EOL care preferences. In fact, the earlier these conversations take place, the more likely it is that an individual's wishes will be respected.
2. Use open-ended questions: Asking open-ended questions can help initiate conversations about EOL care preferences. For example, "Have you thought about what you would want if you were in a situation where you needed aggressive medical treatment?"
3. Be patient and understanding: Recognize that discussing EOL care preferences can be difficult and emotional for both the individual and their healthcare providers. Be patient and understanding throughout the process.

Glossary:
- End-of-life (EOL): Medical and supportive care provided to individuals who are nearing the end of their lives.
- Palliative care: A specialized form of medical care that focuses on relieving pain and symptoms and improving quality of life for individuals with serious illnesses.
- Hospice care: A form of palliative care provided to individuals who are expected to have six months or less to live.

Conclusion:
Understanding the preferences and communication patterns related to EOL care among older adults is essential for providing high-quality, patient-centered care. By initiating conversations about EOL care preferences and communicating these preferences to healthcare providers, individuals can ensure that their wishes are respected and that they receive the best possible care during this difficult time.

**Section 3: Techniques Used in Documentaries**

Documentaries use a variety of techniques to engage viewers and tell a compelling story. These techniques include interviews, archival footage, re-enactments, and narration. Interviews allow viewers to hear directly from people involved in the story being told, while archival footage provides visual evidence of past events. Re-enactments help viewers visualize events that were not captured on camera, and narration provides context and background information.

**Section 4: Role of Documentaries in Society**

Documentaries play an important role in society by providing information and raising awareness about important issues. They can shed light on hidden or underreported stories, expose injustices, and inspire change. Documentaries can also challenge viewers' assumptions and beliefs, and encourage critical thinking about complex issues.

**Section 5: Self-Debating Discussion**

text: I felt like painting the other day, and so I decided to decorate a blank pencil bag (or you could use it for whatever) that I bought at Hobby Lobby awhile back. I did one once before freehanded (it was an MGMT one!), but I wanted to try out painter's tape this time. I made some triangles and rectangles with the painter's tape first, and then pretty much just swirled random colours around. Then I removed the tape and wala! The paint went under the tape in a couple of places, but I really like the outcome anyway!

Q:

Uniform Integrbility

I need to show that if $|f_n|\leq g$, and $g$ is integrable, then $\{f_n\}$ is uniformly integrable, i.e., $\underset{a\rightarrow\infty}\lim\sup_n\int_{[|f_n|\geq a]} |f_n| d\mu=0$.
Here is how I thought about it: Since $|f_n|\leq g$, and $g$ is integrable, then each $f_n$ is integrable. Thus, for each $n$, $|f_n| I_{[|f_n|\geq a]}\leq |f_n|$ and $|f_n| I_{[|f_n|\geq a]}\rightarrow 0$ almost everywhere, thus, by Lebesgue dominated convergence theorem, we have
$\underset{a\rightarrow\infty}\lim\int_{[|f_n|\geq a]} |f_n|d\mu=0$ for each $n$, and hence,
$$0=\sup_n \lim_{a\rightarrow\infty}\int_{[|f_n|\geq a]}|f_n|d\mu=\lim_{a\rightarrow\infty}\sup_n\int_{[|f_n|\geq a]}|f_n|d\mu.$$
However, I am not so sure about the last step of interchanging the limit and supremum? Any thoughts?

A:

It might work to consider that $\sup_n |f_n|$ itself is measurable and bounded by $g$, so it's integrable; and $$\lim_{a \rightarrow \infty} \int_{|f_k| \ge a} \sup_n |f_n| \, \mathrm{d}\mu = 0 \; \; \mathrm{for} \; \mathrm{every} \; k$$ by the argument you gave above. This should be enough.

Lesson: Uniform Integrability

Introduction:

In this lesson, we will learn about uniform integrability and how to show that a sequence of functions is uniformly integrable. We will use the concept of integrability and the Lebesgue Dominated Convergence Theorem to prove this.

Section 1: What is Uniform Integrability?

Uniform integrability is a property of a sequence of functions that states that if each term of the sequence is bounded by another function, and that other function is integrable, then the sequence itself is uniformly integrable. This means that the limit of the supremum of the integrals of the sequence as the bounding function approaches infinity is zero.

Section 2: Proof of Uniform Integrability

To prove that a sequence of functions $\{f_n\}$ is uniformly integrable, we must show that:

1. For each $n$, $|f_n| \leq g$, and $g$ is integrable.
2. $\underset{a\rightarrow\infty}\lim\sup_n\int_{[|f_n|\geq a]} |f_n| d\mu=0$.

Proof:

Since $|f_n|\leq g$, and $g$ is integrable, then each $f_n$ is integrable. Thus, for each $n$, $|f_n| I_{[|f_n|\geq a]}\leq |f_n|$ and $|f_n| I_{[|f_n|\geq a]}\rightarrow 0$ almost everywhere, thus, by Lebesgue dominated convergence theorem, we have

$$\underset{a\rightarrow\infty}\lim\int_{[|f_n|\geq a]} |f_n|d\mu=0$$ for each $n$, and hence,
$$0=\sup_n \lim_{a\rightarrow\infty}\int_{[|f_n|\geq a]}|f_n|d\mu=\lim_{a\rightarrow\infty}\sup_n\int_{[|f_n|\geq a]}|f_n|d\mu.$$

Conclusion:

By proving that the sequence of functions $\{f_n\}$ satisfies the conditions for uniform integrability, we have shown that it is uniformly integrable. This means that the limit of the supremum of the integrals of the sequence as the bounding function approaches infinity is zero.

Glossary:

- Integrability: A function is integrable if there exists a function that is the integral of the original function.
- Lebesgue Dominated Convergence Theorem: A theorem that allows us to interchange the limit and supremum when dealing with dominated convergent sequences.

Exercises:

1. Find an example of a sequence of functions that is not uniformly integrable.
2. Prove that if a sequence of functions is pointwise bounded and has a pointwise convergent subsequence, then it is uniformly integrable.
3. Use the concept of uniform integrability to prove the Portmanteau Theorem.


text: Abstract. High purity Pb-doped CdZnTe single crystals were grown by using the vertical Bridgman method. Their electrical properties and X-ray spectrum were investigated. The doping concentration of Pb was about 1 × 1019 cm- 3. The resistivity of Pb-doped CdZnTe single crystal was 2 × 109 Ω cm. The temperature dependence of the resistivity of these crystals was examined between the region of 200 and 300 K. The plot of log (ρ) versus 1000 / T was represented by a straight line with a slope of 380 meV. From the PL spectrum, we have confirmed that type conversion from p to n-type conductivity originated from the compensation process of Cd vacancies, which are the most abundant acceptors in CdZnTe. Also, the effects of Pb-doping on the mobility and X-ray spectra were studied by time-of-flight (TOF) and 241Am spectrum measurements.. Keywords. - CdZnTe:Pb. - X-ray detector. - X-ray spectrum.

Lesson: Understanding Scientific Articles

Introduction:
Scientific articles are written to share new research findings with other scientists. They are usually published in scientific journals, which are peer-reviewed publications that ensure the accuracy and quality of the research. Reading scientific articles can help you learn more about a specific topic or field of study. However, they can be difficult to understand because they use specialized language and assumptions that you may not be familiar with. In this lesson, we will learn how to read and understand scientific articles.

Section 1: Reading Scientific Articles

1.1. Start with the abstract
The abstract is a brief summary of the article that appears at the beginning of the paper. It provides an overview of the study's objectives, methods, results, and conclusions. Reading the abstract first will give you an idea of what the study is about and whether it is relevant to your interests.

1.2. Familiarize yourself with the terminology
Scientific articles use specialized language and abbreviations that may be unfamiliar to you. Take the time to look up any unfamiliar terms or abbreviations in the glossary or online resources. This will help you understand the article better.

1.3. Pay attention to the structure
Scientific articles typically follow a specific structure, including an introduction, methods, results, discussion, and conclusion. As you read, keep track of where you are in the article and how the information relates to the overall structure.

1.4. Look for the hypothesis and evidence
In most scientific articles, there is a hypothesis (a statement of what the researchers expect to find) and evidence (the results of their experiments). Read carefully to see if the evidence supports or refutes the hypothesis.

1.5. Consider the implications
As you read, think about how the findings of the study might impact the field of research or society as a whole. This will help you understand the significance of the study and its potential contributions to the scientific community.

Section 2: Critical Thinking and Analysis

2.1. Ask questions
As you read, ask yourself questions about the study, such as "What did the researchers do?" or "How does this study relate to other research in the field?" This will help you engage with the material and better understand the study's significance.

2.2. Evaluate the evidence
Scientific studies rely on evidence to support their conclusions. As you read, evaluate the strengths and weaknesses of the evidence presented. Consider whether the evidence is sufficient to support the conclusions drawn by the researchers.

2.3. Consider alternative explanations
Sometimes, the evidence presented in a study may not be enough to confirm or refute a hypothesis. Consider whether there may be alternative explanations for the results that have not been explored by the researchers.

2.4. Think critically about the conclusions
Evaluate the conclusions drawn by the researchers based on the evidence presented. Are the conclusions supported by the data? Are there any limitations or assumptions that may affect the validity of the conclusions?

Section 3: Glossary

- Abstract: A brief summary of a scientific article that appears at the beginning of the paper.
- Hypothesis: A statement of what the researchers expect to find in their study.
- Evidence: The results of experiments conducted to test the hypothesis.
- Peer-reviewed: A publication in which other experts in the field review the research before it is published to ensure its accuracy and quality.
- Terminology: Specialized language used in a particular field of study.
- Glossary: A list of terms and their definitions, often found at the end of a scientific article.

Conclusion:
Reading and understanding scientific articles requires careful attention to detail and critical thinking skills. By following the steps outlined in this lesson, you can improve your ability to read and understand scientific articles, allowing you to engage with new research findings and apply them to your own work.

Lesson Title: Economic and Political Influence on Global Trade

Lesson Overview:
In this lesson, we will explore the economic and political factors that influence global trade. We will examine how countries like the United States, West Germany, Japan, Italy, Iran, and Saudi Arabia have used their economic and political power to shape international trade. Additionally, we will discuss the importance of critical thinking and analysis when evaluating the impact of these factors on global trade.

Objectives:
By the end of this lesson, students will be able to:
- Identify the economic and political factors that influence global trade.
- Analyze how countries use their economic and political power to shape international trade.
- Evaluate the impact of these factors on global trade.
- Apply critical thinking skills to analyze and evaluate information related to global trade.

Section 1: Introduction to Global Trade
Global trade refers to the exchange of goods, services, and capital between countries. It is an essential aspect of the modern world economy, as it allows countries to specialize in producing goods and services that they are best at and trade with other countries. However, global trade is not without its challenges, as economic and political factors can significantly influence the way countries interact with each other in the global market.

Section 2: Economic Factors
One of the most significant economic factors that influence global trade is the balance of trade. A country's balance of trade refers to the difference between the value of its imports and exports. When a country has a positive balance of trade, it means that it exports more than it imports, and when it has a negative balance of trade, it means that it imports more than it exports. Countries with a positive balance of trade often have an advantage in global trade, as they can sell their products to other countries at a profit. However, countries with a negative balance of trade may struggle to compete in the global market.

Another economic factor that influences global trade is the value of currencies. The value of a country's currency can affect the price of its goods and services in foreign markets. For example, if the value of the US dollar is high compared to other currencies, US exports may become more expensive, making them less competitive in the global market.

Section 3: Political Factors
Political factors also play a significant role in global trade. Countries may use trade agreements, tariffs, and other policies to influence their trade relationships with other countries. For example, some countries may use tariffs to protect their domestic industries from foreign competition. Others may enter into free trade agreements, which allow for the free flow of goods and services between countries without tariffs or other trade barriers.

Countries may also use political influence to shape global trade. For example, powerful countries like the United States may use their economic and military power to influence trade relationships with other countries. They may offer economic aid or military protection in exchange for favorable trade deals.

Section 4: Analysis and Critical Thinking
As we have seen, economic and political factors can significantly influence global trade. To evaluate the impact of these factors, we must use critical thinking skills to analyze and evaluate information related to global trade. We must ask questions like, "How do these factors affect different countries?" and "What are the long-term consequences of these factors on global trade?" By applying critical thinking skills, we can better understand the complexities of global trade and make informed decisions about how to engage with the global market.

Glossary:
- Balance of trade: The difference between a country's imports and exports.
- Free trade agreement: An agreement between two or more countries to remove trade barriers and allow for the free flow of goods and services.
- Tariff: A tax imposed by a government on goods and services imported from other countries.

Conclusion:
In conclusion, economic and political factors play a crucial role in shaping global trade. By understanding these factors and applying critical thinking skills, we can better evaluate their impact on the global market. As we continue to engage in global trade, it is essential to remain vigilant and informed about the factors that influence our interactions with other countries.

Lesson Title: Understanding JavaScript Basics

**Introduction:**

JavaScript is a programming language that allows you to create interactive web pages and web applications. It is an essential part of web development and is used by millions of developers worldwide. In this lesson, we will explore the basics of JavaScript, including its syntax, variables, data types, and control structures.

**Section 1: Getting Started with JavaScript**

**Topic 1: What is JavaScript?**

JavaScript is a high-level, interpreted programming language that is commonly used to create interactive elements on web pages. It was first introduced in 1995 by Netscape Communications Corporation and has since become a standard feature of all major web browsers.

**Topic 2: Why learn JavaScript?**

There are many reasons why learning JavaScript is beneficial. Here are a few:

- JavaScript is essential for web development: Almost every modern web page uses JavaScript in some way, whether it's for form validation, drop-down menus, or animations.
- JavaScript can improve user experience: With JavaScript, you can create dynamic and interactive web pages that respond to user input.
- JavaScript is versatile: You can use JavaScript to create web applications, mobile apps, and even desktop applications.

**Topic 3: Setting up a JavaScript environment**

To get started with JavaScript, you need a web browser that supports the language. Most modern browsers, such as Google Chrome, Mozilla Firefox, and Microsoft Edge, support JavaScript.

**Section 2: Basic Syntax and Variables**

**Topic 1: Understanding JavaScript syntax**

JavaScript is a relatively easy language to learn because it has a simple and consistent syntax. Here are some basic rules to follow:

- All code is written within curly braces `{}`.
- Indentation is not important in JavaScript, but it is recommended to use it for readability.
- Comments begin with `//` and continue to the end of the line.
- Variables are defined using the `var` keyword.
- Commas separate values in a string.

**Topic 2: Working with variables**

A variable is a named storage location that can hold a value. In JavaScript, you can create variables of different data types, such as numbers, strings, and booleans.

Here's an example of creating and assigning values to variables:
```javascript
// Create a variable called "name" and assign the value "John"
var name = "John";
// Create a variable called "age" and assign the value 25
var age = 25;
```

**Section 3: Data Types**

**Topic 1: Understanding data types**

In JavaScript, there are several data types that represent different kinds of values. These include:

- Number: A numerical value, such as 42 or 0.5.
- String: A sequence of characters, enclosed in quotes, such as "hello" or "world".
- Boolean: A logical value, either true or false.
- Null: A special value that represents nothing or null.
- Undefined: A special value that represents something that has not yet been defined.

**Topic 2: Working with data types**

You can work with different data types in JavaScript by using appropriate operators and functions. Here are some examples:

- Comparing numbers: `if (x > y)`
- Comparing strings: `if (x === y)`
- Checking if a value is null or undefined: `if (value === null || value === undefined)`
- Converting a number to a string: `String(number)`
- Converting a string to a number: `Number("42")`, which returns 42.

**Section 4: Control Structures**

**Topic 1: Understanding control structures**

Control structures are essential for organizing code and making decisions based on certain conditions. In JavaScript, there are three main control structures:

- If/else: Executes one block of code if a certain condition is true, and another block if the condition is false.
- For loop: Repeats a block of code for a specified number of iterations or until a certain condition is met.
- While loop: Repeats a block of code while a certain condition is true.

**Topic 2: Using control structures**

Here are some examples of how to use control structures in JavaScript:

- Checking if a number is positive:
```javascript
function isPositive(num) {
  if (num > 0) {
    return true;
  } else {
    return false;
  }
}
```

- Printing numbers from 1 to 10:
```javascript
for (let i = 1; i <= 10; i++) {
  console.log(i);
}
```

- Adding numbers until the sum reaches 100:
```javascript
let sum = 0;
while (sum < 100) {
  sum += 5;
}
console.log(sum); // Output: 100
```

**Conclusion**

In this lesson, we covered the basics of JavaScript, including its syntax, variables, data types, and control structures. By understanding these concepts, you can begin to create interactive and dynamic web pages and web applications.

**Glossary**

- JavaScript: A programming language used for web development.
- Curly braces: Symbols `{}` used to enclose code blocks in programming languages.

Effect of growth hormone-releasing factor on phosphoinositide hydrolysis in somatotrophs.
We studied the role of the phosphatidylinositol system in the action of growth hormone-releasing factor (GRF). We asked whether GRF stimulates the activity of phospholipase C by determining GRF-induced changes in 32P labeling of the individual phosphoinositides and inositol phosphates in purified rat somatotrophs. The somatotrophs were challenged with GRF (10(-7)M) for 0.33, 1, 3, 10, 30, and 90 min. GRF did not significantly or consistently alter 32P incorporation into phosphatidylinositol bisphosphate (PIP2), phosphatidylinositol monophosphate (PIP), or phosphatidylinositol (PI), except for a small reduction in PIP labeling at 90 min. In general the level of 32P incorporation into the inositol phosphates did not increase but instead decreased with GRF. There was a small but significant reduction of labeling of inositol trisphosphate (IP3) at 90 min of GRF incubation. There were also small but significant decreases in 32P incorporation into inositol bisphosphate (IP2) at 0.33, 3, and 30 min. GRF did not significantly alter 32P labeling of inositol monophosphate (IP). These results indicate that GRF does not stimulate phospholipase C activity in somatotrophs. We conclude that the phosphatidylinositol second messenger system does not play an essential role in the action of GRF.

Lesson: Introduction to Phosphoinositides

Phosphoinositides are a group of signaling molecules that play a crucial role in cellular processes such as cell growth, division, and communication. They are composed of a phosphate group attached to the inositol ring. In this lesson, we will learn about the structure and function of phosphoinositides, their role in cellular signaling, and how they can be regulated by external factors such as growth hormone-releasing factor (GRF).

Section 1: Introduction to Phosphoinositides

Phosphoinositides are a family of membrane phospholipids that contain a phosphate group attached to the 3',4'-bisphosphate position of the inositol ring. There are several types of phosphoinositides, including phosphatidylinositol (PI), phosphatidylinositol 4-phosphate (PI4P), phosphatidylinositol 5-phosphate (PI5P), and phosphatidylinositol 3,4,5-trisphosphate (PIP3).

Phosphoinositides are involved in various cellular processes, including cell growth, division, and communication. They act as second messengers in signal transduction pathways, regulating the activity of proteins such as kinases and phosphatases. Additionally, phosphoinositides can be cleaved by enzymes called phosphatases to generate lipid second messengers such as inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG).

Section 2: Role of Phosphoinositides in Cellular Signaling

Phosphoinositides play a critical role in cellular signaling by acting as second messengers in various signal transduction pathways. For example, PIP3 is a key molecule in the activation of protein kinase B (PKB/Akt), which is involved in cell survival, growth, and metabolism. Similarly, PI(3,4,5)P3 is involved in the activation of phospholipase C (PLC), which generates IP3 and DAG, two molecules that regulate calcium signaling and membrane trafficking, respectively.

Section 3: Regulation of Phosphoinositides by External Factors

External factors such as hormones, neurotransmitters, and growth factors can modulate the levels of phosphoinositides in cells. For example, growth hormone-releasing factor (GRF) has been shown to affect the phosphoinositide system in somatotrophs, a type of cell involved in growth hormone secretion.

In a study conducted by researchers, the effect of GRF on phosphoinositide hydrolysis in somatotrophs was investigated. The results showed that GRF did not significantly or consistently alter the labeling of PIP2, PIP, or PI, except for a small reduction in PIP labeling at 90 min. However, there was a small but significant reduction of labeling of inositol trisphosphate (IP3) at 90 min of GRF incubation.

Section 4: Conclusion

In conclusion, phosphoinositides are essential signaling molecules that play a crucial role in various cellular processes. They can be regulated by external factors such as hormones and growth factors, which can modulate their levels in cells. Understanding the structure and function of phosphoinositides, as well as their role in cellular signaling, is important for advancing our knowledge of cellular processes and developing new therapeutic strategies for various diseases.


text: Critical Habitat Management Portal Online. A new tool for landowners is now available from the Resources First Foundation.. “The Critical Habitat Management Portal (CHMP) is designed to help private landowners manage candidate, threatened, and endangered species on their land by providing information on the species, the conservation measures needed to restore and conserve its habitat, and the professionals, organizations, and programs that can provide financial and technical assistance to implement the desired conservation practices.. The United States Fish and Wildlife Service will be reviewing hundreds of species over the next decade to determine if it is necessary to provide them with protection under the Endangered Species Act. Unlike listing decisions in the past, many of the species that will undergo review reside mostly on private.

This is one of the pages, rendered in three possible ways I'm considering - this is where I'll need your advice on which is the best to follow.. The first one is simply straight up black and white. This would give me the quickest turnaround time in developing my novels, should some nice person be willing to publish it.. Next is greyscale. This sample is a bit darker than what I'm after but you get the idea. This way allows for a bit of texture and depth than B&W and the greyscaliness might make it a bit more 'artsy' and mature than colour. I don't know.. This is the way I'd prefer to have it, but it takes the longest time to complete as opposed to the others. Also, I'm using the CMYK colour scheme and there are times when I just can't get the right shade.

Q:

Extracting some part of a satellite image using mask?

I'm trying to extract some part of a satellite Landsat-8 image. using another image.
I have the following satellite image:

and I want to keep only the areas from the satellite image which  are highlighted as green in the other image in below.
(white and green image is the crop data layer for the same location as my satellite image):

Basically saying I want to keep the corresponding green areas in my original satellite image and delete the corresponding white areas from the original satellite image which is shown at top.
How can I do that?

A:

The tool you're looking for is called 'Extract by Mask' in ArcMap, but other packages have equivalents
use Raster Calculator and enter this command:
Con("raster" == green_value, 1)

if you want to keep the original value:
Con("raster" == green_value, "raster")

you can replace == with other conditionals (e.g., >, <, >=, <=, !=)
**Replace green_value with the value that represents green, then use extract by mask with the new raster. Replace "raster" with the name of your raster layer -- keep the quotes.

Lesson:

**Title: Extracting Parts of Images using Masks**

**Level: Primary through High School**

**Overview:** In this lesson, we will learn how to extract parts of an image using masks. We will use the concept of bitwise operations to create a mask, and then use it to extract the desired part of an image.

**Objective:** By the end of this lesson, students will be able to:

1. Explain what a mask is and why it is used in image processing.
2. Create a mask using bitwise operations.
3. Use a mask to extract parts of an image.
4. Apply the learned concept to real-world scenarios.

**Section 1: Introduction**

**Topic 1.1: What is a Mask?**

A mask is a grayscale or color image that acts as a filter to selectively reveal or hide parts of an underlying image. It is commonly used in image processing to extract parts of an image, apply special effects, or enhance the quality of an image.

**Topic 1.2: Why use Masks in Image Processing?**

Masks are useful in image processing because they allow us to selectively modify parts of an image without affecting others. This can save time and computational resources compared to editing the image directly.

**Section 2: Creating a Mask**

**Topic 2.1: Bitwise Operations**

Bitwise operations involve manipulating individual bits of binary numbers. They are commonly used in computer programming and digital electronics.

**Topic 2.2: Creating a Mask using Bitwise Operations**

We can create a mask by applying bitwise operations to a grayscale image. One common method is to use a threshold value to convert the image to a binary image, and then apply logical operators like "AND" and "OR" to create a mask.

**Example:**

1. Open an image in an image editing software.
2. Convert the image to grayscale.
3. Adjust the contrast to bring out details in the dark areas.
4. Set the threshold value to create a binary image.
5. Apply logical operators like "AND" and "OR" to create a mask.

**Section 3: Extracting Parts of an Image using a Mask**

**Topic 3.1: Using a Mask to Extract Parts of an Image**

Once we have a mask, we can use it to extract parts of an image. We can do this by using the "AND" operator between the original image and the mask. This will result in a new image that contains only the areas where the mask and the original image overlap.

**Example:**

1. Open the image with the mask.
2. Apply the "AND" operator between the original image and the mask.
3. The resulting image will contain only the areas where the mask and the original image overlap.

**Section 4: Real-World Scenarios**

**Topic 4.1: Applying Masks in Photoshop**

In Photoshop, we can use masks to selectively edit parts of an image. For example, we can use a mask to remove a person from a photo without affecting the background.

**Topic 4.2: Applying Masks in Image Processing Software**

In image processing software, we can use masks to apply filters or effects selectively. For example, we can use a mask to sharpen only the edges of an image, while leaving the center soft.

**Glossary:**

- Mask: A grayscale or color image that acts as a filter to selectively reveal or hide parts of an underlying image.
- Bitwise operations: Manipulating individual bits of binary numbers.
- Threshold value: A value that separates an image into two categories (e.g., black and white).
- Logical operators: Operators like "AND", "OR" that perform bitwise operations on binary numbers.

**Conclusion:**

In this lesson, we learned how to create a mask using bitwise operations, and how to use a mask to extract parts of an image. We also applied the concept to real-world scenarios, such as using masks in Photoshop and image processing software. By understanding the concept of masks, we can improve our ability to manipulate and enhance images.

Integrated-optic acoustically tunable reflection filter.
We demonstrate a two-stage, integrated-optic, acoustically tunable filter formed by reflecting the output of a single stage acousto-optic filter back through the filter by means of an integral mirror. Relative to a single-stage device, this double-pass configuration provides greatly improved sidelobe suppression (to approximately -20 dB) and a 72% reduction in filter bandwidth (to less than 0.9 nm at a wavelength of 1.52 microm). The performance of this device is shown to be equal to the far more difficult to fabricate cascaded pair of strictly matched acousto-optic filters.

Lesson: Integrated Optics and Acoustic Tunable Reflection Filters

Introduction:
In this lesson, we will learn about integrated optics and acoustic tunable reflection filters. We will explore what they are, how they work, and their applications.

What is Integrated Optics?
Integrated optics refers to the combination of multiple optical components such as waveguides, lasers, and detectors into a single chip or substrate. This technology allows for the miniaturization and cost reduction of optical systems.

What is an Acoustic Tunable Reflection Filter?
An acoustic tunable reflection filter is a device that can change its reflection properties by applying an external acoustic signal. This allows for the filtering of light based on its wavelength or frequency.

How does an Acoustic Tunable Reflection Filter work?
An acoustic tunable reflection filter works by using a piezoelectric transducer to apply an acoustic signal to a quartz crystal. This signal causes the crystal to vibrate, which in turn changes the path length of the light passing through the crystal. By changing the path length, the filter can selectively reflect certain wavelengths of light while transmitting others.

Applications of Acoustic Tunable Reflection Filters:
Acoustic tunable reflection filters have many applications in fields such as telecommunications, spectroscopy, and optical computing. Some specific applications include:

1. Wavelength selection in optical communication systems
2. Spectral analysis in chemistry and biology
3. Tunable filters for use in optical computers

Conclusion:
In this lesson, we learned about integrated optics and acoustic tunable reflection filters. We explored what they are, how they work, and their applications. By understanding these technologies, we can begin to imagine new ways to manipulate and control light, opening up exciting possibilities for future research and innovation.
