Lesson: Introduction to Brain-Based Methods in Neurodevelopmental Disorders

## Section 1: Theoretical Concepts
In this lesson, we will learn about brain-based methods used to study sensory and perceptual functioning in neurodevelopmental disorders such as autism spectrum disorder (ASD), schizophrenia spectrum disorders (SZS), and others. We will explore how these methods help researchers understand the underlying biological mechanisms of these disorders and contribute to the development of more effective treatments.

## Section 2: Practical Examples
Let's consider a hypothetical example. Imagine a child with ASD who has difficulty processing sensory information. Using EEG, we can measure the electrical activity in the child's brain while they are exposed to different sensory stimuli. By analyzing the EEG data, we can identify abnormal patterns of neural activity that may be contributing to the child's sensory processing difficulties. This information can then be used to develop targeted interventions, such as sensory integration therapy, to improve the child's ability to process and respond to sensory information.

## Section 3: Self-Debating Discussions
One debate in the field of neurodevelopmental disorders is whether sensory processing difficulties are a cause or a consequence of these disorders. Some researchers argue that sensory processing difficulties are a core feature of ASD and other NDDs, while others suggest that these difficulties arise as a result of other underlying factors, such as social impairments or cognitive deficits. What do you think? Do you think sensory processing difficulties are a cause or a consequence of neurodevelopmental disorders? Why?

## Glossary
- EEG: Electroencephalogram, a test that measures the electrical activity in the brain
- MRI: Magnetic Resonance Imaging, a medical imaging technique used to visualize the internal structure of the body
- NDDs: Neurodevelopmental disorders, a group of disorders characterized by abnormal development of the nervous system
- ASD: Autism spectrum disorder, a developmental disorder characterized by difficulties with social interaction and communication, as well as repetitive behaviors
- SZS: Schizophrenia spectrum disorders, a group of mental disorders characterized by symptoms such as hallucinations, delusions, and disorganized thinking
- Pat: Short for "patient"

## Conclusion
In this lesson, we have learned about brain-based methods used to study sensory and perceptual functioning in neurodevelopmental disorders. We have explored how these methods can help researchers understand the underlying biological mechanisms of these disorders and contribute to the development of more effective treatments. We have also considered a hypothetical example of using EEG to study sensory processing difficulties in a child with ASD and engaged in a self-debating discussion about the role of sensory processing difficulties in NDDs. Finally, we have defined key terms related to this topic. By applying these concepts to new problems, we can continue to deepen our understanding of neurodevelopmental disorders and contribute to the development of more effective interventions for those affected by these conditions.

# Lesson 1: Introduction to Election Systems
## I. What is an Election System?
An election system is a process by which people choose leaders or representatives to hold positions of authority in their government. This process ensures that the people's voices are heard and that their leaders are accountable to them.
## II. Types of Election Systems
There are several types of election systems, including:
1. First-past-the-post (FPTP) - This system is used in the United States and many other countries. In this system, the candidate with the most votes wins the election.
2. Proportional representation (PR) - This system is used in many countries around the world. In this system, the number of seats a party gets in the legislature is proportional to the number of votes they receive.
3. Ranked choice voting (RCV) - This system is used in some parts of the United States. In this system, voters rank their choices in order of preference. If no candidate receives a majority of first-choice votes, the candidate with the fewest votes is eliminated, and their votes are redistributed to the remaining candidates based on the second-choice votes.
## III. How do Election Systems Work?
Election systems work by allowing citizens to vote for the candidates they want to represent them. The process varies depending on the type of election system being used. In general, however, there are certain steps that are followed:
1. Voter Registration - Before an election can take place, voters must be registered. This ensures that only eligible citizens can vote.
2. Campaigning - Once voters are registered, candidates begin campaigning. They travel around the country, giving speeches and meeting with voters to try to convince them to support them.
3. Election Day - On election day, voters go to their polling places and cast their ballots. The process varies depending on the type of election system being used.
4. Counting the Votes - After election day, the votes are counted. Again, the process varies depending on the type of election system being used.
5. Declaration of Results - Once all the votes have been counted, the results are declared. The candidate with the most votes (or the most seats, in the case of PR) is declared the winner.
## IV. Conclusion
Election systems are an important part of our democracy. They allow us to choose our leaders and hold them accountable for their actions. By understanding how these systems work, we can become more informed citizens and make better decisions when we vote.

**Lesson:** Introduction to Automobiles

**Objective:** In this lesson, we will learn about the different parts of an automobile and their functions. We will also explore the history of automobiles and how they have evolved over time.

**Section 1: Introduction to Automobiles**

An automobile is a vehicle that is designed to transport people and goods from one place to another. It is also known as a car, motorcar, or simply a car. Cars have become an essential part of modern life, and they come in all shapes and sizes.

**Section 2: History of Automobiles**

The first automobiles were invented in the late 1800s. They were powered by steam engines and were not very reliable. In the early 1900s, cars started to become more popular, and they were powered by gasoline engines. Over time, cars have become more advanced, with better engines, suspensions, and safety features.

**Section 3: Understanding Automobiles**

Cars are made up of many different parts, each with its own function. Here are some of the most important parts of a car:

- Engine: This is the part of the car that makes it move. It burns fuel to create power, which is then transferred to the wheels.
- Transmission: This is the part of the car that controls how the power from the engine is used. It can change gears to make the car go faster or slower.
- Suspension: This is the part of the car that helps it ride smoothly over bumps and other obstacles. It includes springs, shock absorbers, and other components.
- Brakes: This is the part of the car that stops it from moving. It uses friction to slow down the car when the brake pedal is pressed.
- Wheels: These are the round things that the car sits on. They turn when the car goes around corners and help to keep the car stable on the road.

**Section 4: Practical Examples**

Let's take a look at some practical examples of how these parts work together to make a car go. Imagine you are driving a car with a gasoline engine. The engine burns fuel to create power, which is then transferred to the wheels through the transmission. The suspension helps to keep the car stable on the road, while the brakes slow it down when you need to stop. The wheels turn to help the car go around corners.

**Glossary:**

- Engine: The part of the car that makes it move.
- Transmission: The part of the car that controls how the power from the engine is used.
- Suspension: The part of the car that helps it ride smoothly over bumps and other obstacles.
- Brakes: The part of the car that stops it from moving.
- Wheels: The round things that the car sits on.

**Conclusion:**

In this lesson, we learned about the different parts of an automobile and their functions. We also explored the history of automobiles and how they have evolved over time. By understanding how these parts work together, we can appreciate the complexity and ingenuity of these machines.

Lesson: Introduction to Nutrition

Overview:
Nutrition is the process by which organisms get or produce the materials they need to live. In this lesson, we will learn about the basics of nutrition, including the three macronutrients needed for energy, the role of vitamins and minerals in our diet, and how to make healthy food choices.

Section 1: Macronutrients

Macronutrients are the nutrients that our body needs in relatively large amounts to function properly. There are three main macronutrients: carbohydrates, proteins, and fats.

**Carbohydrates**: Carbohydrates are the body's main source of energy. They are found in foods such as bread, pasta, rice, and fruits. The body uses carbohydrates to fuel our cells, tissues, and organs.

**Proteins**: Proteins are necessary for the growth and repair of tissues in the body. They are found in foods such as meat, fish, eggs, dairy products, and beans.

**Fats**: Fats are needed for the absorption of certain vitamins and minerals, and for the proper functioning of the brain and nervous system. They are found in foods such as oils, butter, and fatty meats.

Section 2: Vitamins and Minerals

Vitamins and minerals are essential for the body to function properly. They play important roles in the body, such as helping to form bones, regulate the immune system, and convert food into energy.

**Vitamins**: There are 13 vitamins that the body needs, including vitamins A, C, D, E, K, and B vitamins (B1, B2, B3, B5, B6, B7, B9). These vitamins are needed for various functions in the body, such as vision, skin health, and blood clotting.

**Minerals**: There are two types of minerals: macro-minerals (needed in larger amounts) and trace minerals (needed in smaller amounts). Examples of macro-minerals include calcium, magnesium, and potassium. Examples of trace minerals include iron, zinc, and copper.

Section 3: Making Healthy Food Choices

To maintain good health, it is essential to eat a balanced diet that includes a variety of foods from all the food groups. This includes fruits and vegetables, whole grains, lean proteins, and low-fat dairy products.

**Fruits and Vegetables**: Fruits and vegetables provide vitamins, minerals, and fiber, which are essential for good health. Aim to eat at least 5 servings of fruits and vegetables per day.

**Whole Grains**: Whole grains are grains that have not been processed and refined. They are a good source of fiber and other nutrients. Choose whole grain options such as brown rice, whole wheat bread, and quinoa.

**Lean Proteins**: Lean proteins are those that are low in fat and high in protein. Choose lean protein options such as chicken, fish, beans, and tofu.

**Low-Fat Dairy Products**: Low-fat dairy products such as milk, yogurt, and cheese are good sources of calcium and other nutrients. Choose low-fat or fat-free options whenever possible.

Conclusion:

In conclusion, nutrition is an important part of maintaining good health. By understanding the basics of macronutrients, vitamins and minerals, and making healthy food choices, we can ensure that our bodies are getting the nutrients they need to function properly.

Q:

What is this type of graphics application called?

I want to make a picture where I have a lot of image elements that will repeat--e.g., stick figures in certain body positions.  I'd like to be able to create a library of these image elements by drawing them or importing them as JPG/PNG/etc. and be able to select them and drag them from the library onto my main image.  I want to resize them as needed. Then I want to be able to select them later and move them around.  I also want to be able to combine elements to make a new element--for example, if I have a "hat" element and a "stick figure" element, then I want to be able to put the hat on the stick figure and add it to the library as a "stick figure wearing a hat" element.
What is this type of application called?

A:

I want to draw some vector objects using primitives.

Adobe Illustrator

Then I want to create groups of these vector objects that are themselves vector objects, groups of groups, and so on. I want to be able to modify an object and have its results reflected in all instances of that object

Adobe Illustrator Symbols

I've read that I can do this with a Smart Object in Photoshop.

Forget Photoshop if you are working with vector primitives. You may as well stick to Illustrator. Photoshop offers no benefit based on the above comments.

Once I have the massive composite vector object that comprises the entire image, I want to export the results to a JPG or print the object on an arbitrarily large sheet of paper.

Again, Adobe Illustrator.
There amy be other software which will do all this. The basics are simply a vector editing application which has a feature similar to Adobe Illustrator Symbols.

Lesson: Understanding the Digestive System

Introduction:
The digestive system is responsible for breaking down food into smaller components that can be absorbed and used by the body. In this lesson, we will learn about the different parts of the digestive system and how they work together to process food.

Section 1: Overview of the Digestive System
- The digestive system includes the mouth, esophagus, stomach, small intestine, large intestine, and anus.
- Food enters the mouth, where it is chewed and mixed with saliva, which contains enzymes that begin the breakdown of carbohydrates.
- The swallowed food then passes down the esophagus, a muscular tube that contracts to move the food to the stomach.
- The stomach contains acids and enzymes that further break down the food.
- From the stomach, the food moves into the small intestine, where nutrients are absorbed into the bloodstream.
- The large intestine absorbs water and electrolytes, forming solid waste that is eventually excreted through the anus.

Section 2: Digestion and Absorption
- Digestion is the process of breaking down food into smaller components.
- Enzymes and acids in the stomach break down proteins, fats, and carbohydrates.
- The small intestine is lined with tiny finger-like projections called villi, which increase the surface area for absorption.
- Nutrients are absorbed into the bloodstream through the walls of the small intestine.
- The large intestine absorbs water and electrolytes, forming solid waste that is eventually excreted through the anus.

Section 3: Excretion
- Excretion is the process of removing waste products from the body.
- Solid waste is formed in the large intestine and eventually excreted through the anus.
- Liquid waste, such as urine, is produced by the kidneys and excreted through the urethra.

Conclusion:
Understanding the digestive system is important for maintaining good health. By knowing how food is processed and what happens to waste products, we can make informed decisions about what we eat and drink. This knowledge can also help us identify potential problems and seek medical attention when necessary.

Glossary:
- Digestive system: A group of organs that work together to process food and absorb nutrients.
- Enzyme: A substance that speeds up chemical reactions in the body.
- Villi: Tiny finger-like projections that increase the surface area for absorption.
- Excretion: The process of removing waste products from the body.

Self-Debate:
Why is it important to understand the digestive system? How does this knowledge impact our daily lives?

Section 1: The Role of a Real Estate Agent

Topic 1: What does a real estate agent do?
A real estate agent is a professional who helps people buy and sell properties. They act as a middleman between the buyer and seller, negotiating the best possible price and terms for both parties.

Topic 2: How does a real estate agent get paid?
Real estate agents typically work on commission, which means they earn a percentage of the sale price of the property. They may also charge a flat fee or hourly rate for their services.

Section 2: Market Research

Topic 1: Why is market research important?
Market research is essential because it helps you determine the value of a property and whether it's worth buying or selling. It involves analyzing data such as recent sales prices, property values, and trends in the real estate market.

Topic 2: How do you conduct market research?
To conduct market research, you can use online resources such as Zillow or Redfin, or hire a professional appraiser to evaluate the property. You should also consider factors such as location, size, and condition of the property, as well as any recent renovations or upgrades.

Section 3: The Sales Process

Topic 1: What happens during the sales process?
The sales process typically involves several steps, including listing the property, marketing it to potential buyers, negotiating offers, and finalizing the sale. Your real estate agent will guide you through each step and help you make informed decisions along the way.

Topic 2: What documents do you need to sell a property?
To sell a property, you'll need to provide several documents, including a deed, title search, and settlement statement. These documents verify your ownership of the property and outline any outstanding liens or fees.

Conclusion:
Understanding real estate sales is crucial if you're considering buying or selling a property. By working with a knowledgeable real estate agent and conducting thorough market research, you can make informed decisions and achieve a successful outcome.

Show HN: AWS CloudFront (CDN) for dynamically generated content - zubairov
http://blog.elastic.io/post/22773181715/how-we-use-amazon-cloudfront-for-dynamically-generated

======
mryan
Nice post, thanks for sharing.

I recently had a similar problem - I needed to serve dynamically resized
images via CloudFront (with the images being stored in S3). Images are resized
on-demand - if they exist they are served directly from S3. If not, they are
resized and stored in S3, then the next request will serve them directly from
S3.

It works rather well, although it is quite susceptible to the thundering herd
problem - putting it behind a reverse proxy that supports collapsed forwards
would probably help here.

I've put the WSGI app I used for this on github - hopefully someone finds it
useful! <https://github.com/mikery/s3cacher>

------
tfennelly
Impressive. On FoxWeave, we're using Rackspace (at the moment). Fairly sure
they don't offer anything like this, which probably means we'll have to use a
caching reverse proxy.

Nice post... thanks.

------
drobiazko
What about the CloudFront pricing? Is it cheaper than scaling own servers?

~~~
zubairov
Good question. It depends on the caching strategy. As we essentially serve
Gists we have two types of URLs one something like [gist-id]/ meaning the
latest version of that particular gist and another URL is [gist-id]/[revision-
id] which is a particular revision. For 'latest' URL we just do a redirect to
particular latest version. For first type of resource we have 60 seconds
expire, however it is also not too expensive to re-generate it. For second
type of resource (with particular revision) we have much higher expire time
(several days). By this type of caching strategy I assume we will get only 20%
of all requests to our servers so saving is significant.

~~~
madarco
Since there is a 1005ms latency for a cache-miss, for the average user the
loading times are shorter? (based on your data on hit/miss ratio)

I was thinking to use Cloudfront to lower the latency (not costs) for dynamic
resources, because in Italy there isn't an ec2 datacenter, but there is an
edge location for Cloudfront.

~~~
zubairov
Hi,

No 1005 ms was not a cache miss it was a request to the origin server. Latency
was 799 ms.

I assume CloudFront will contribute some latency, however in our case (we are
using Heroku) our servers were already on Amazon platform, therefore
CloudFront --> our server latency should be significantly lower. So CloudFront
cache miss latency for the enduser will be not significantly higher than
origin server latency for the enduser.

~~~
madarco
Thanks, I've asked because I've read somewhere that an average request for a
"Miss from cloudfront" object was ~1 second, and I thought that your data was
confirming that value.

Lesson 1: Introduction to Caching

Caching is an important technique used in computer science and programming to improve performance and reduce costs. It involves storing data in memory so that it can be accessed more quickly than reading it from a slow storage device. In this lesson, we will explore the basics of caching and how it can be used to optimize web applications.

**Section 1: What is Caching?**

Caching is the process of storing frequently accessed or frequently changing data in a cache. A cache is a high-speed memory that stores data temporarily while it is being used. The idea behind caching is to reduce the number of times that data needs to be retrieved from a slower storage device, such as a hard drive or solid-state drive. This can significantly improve the performance of a system.

**Section 2: Why Use Caching?**

There are several reasons why caching is useful. First, it can improve performance by reducing the time it takes to access data. Second, it can reduce the load on a server or storage device by reducing the number of requests that need to be processed. Finally, it can save money by reducing the amount of hardware needed to store data.

**Section 3: Types of Caching**

There are two main types of caching: client-side caching and server-side caching. Client-side caching occurs when a user's web browser stores a copy of a web page or resource locally. Server-side caching occurs when a web server stores a copy of a web page or resource in its memory. Both types of caching can improve performance, but they have different advantages and disadvantages.

**Section 4: How to Implement Caching**

To implement caching, you need to identify which data should be cached and how long it should be cached for. You also need to choose the appropriate caching strategy, such as memoization or lazy loading. Finally, you need to decide whether to use client-side or server-side caching or both.

**Section 5: Examples of Caching**

One example of caching is the use of a CDN (Content Delivery Network) such as Amazon CloudFront. A CDN stores copies of web pages and other resources in multiple locations around the world. When a user requests a resource, the CDN serves it from the location closest to the user, reducing the time it takes to download the resource. Another example of caching is the use of a caching web server such as Apache or NGINX. These servers store frequently accessed resources in memory, reducing the number of times that data needs to be retrieved from a slower storage device.

**Conclusion**

Caching is an important technique that can improve the performance of web applications and reduce costs. By identifying which data should be cached and choosing the appropriate caching strategy, you can significantly improve the speed and efficiency of your web application.

Sequence determination of oligosaccharides and regular polysaccharides using NMR spectroscopy and a novel Web-based version of the computer program CASPER.
A WWW-interface to a program for structure elucidation of oligo- and polysaccharides using NMR data, CASPER, is presented. The interface and the underlying program have been extensively tested using published data and it was able to simulate 13C NMR spectra of >200 structures with an average error of about 0.3 ppm/resonance. When applied to the repeating units of Escherichia coli O-antigens the published structures were found among the five highest ranked structures in 75% of the cases. The average deviation between calculated and experimental 13C chemical shifts was 0.45 ppm. Oligosaccharide spectra were calculated with even better accuracy (0.23 ppm/resonance) and the correct structure was ranked 1st or 2nd in all the cases examined. Additional NMR experiments that may be required to distinguish between candidate structures are aided by the assignments provided by the program. This computational approach is also suitable for use in structural confirmation of chemically or enzymatically synthesized oligosaccharides. The program is found at http://www.casper.organ.su.se/casper.

Lesson: Introduction to NMR Spectroscopy for Sequence Determination of Oligosaccharides and Polysaccharides

Introduction:
Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique used to determine the structure of molecules, including oligosaccharides and polysaccharides. In this lesson, we will learn about NMR spectroscopy, how it can be used to determine the sequence of oligosaccharides and polysaccharides, and how to use a novel Web-based version of the computer program CASPER to analyze NMR data.

Section 1: NMR Spectroscopy Basics

1.1 What is NMR spectroscopy?
NMR spectroscopy is a technique used to study the magnetic properties of atomic nuclei. It involves placing a sample in a strong magnetic field and then applying a radiofrequency pulse to excite the nuclei. The nuclei absorb the radiofrequency energy and then emit it at a specific frequency, which is proportional to their magnetic environment. By measuring the emitted signal, we can obtain information about the structure and dynamics of the molecules in the sample.

1.2 How does NMR spectroscopy work?
In NMR spectroscopy, the sample is placed in a strong magnetic field, which causes the nuclei to align along the direction of the magnetic field. When a radiofrequency pulse is applied, the nuclei absorb the energy and flip into a higher energy state. As they return to their original state, they emit radiofrequency signals that are detected by the spectrometer. The emitted signals are then analyzed to obtain information about the structure and dynamics of the molecules in the sample.

1.3 Why is NMR spectroscopy useful for determining the sequence of oligosaccharides and polysaccharides?
NMR spectroscopy is particularly useful for determining the sequence of oligosaccharides and polysaccharides because it provides detailed information about the chemical environment of the nuclei in the sample. By analyzing the chemical shifts and coupling constants in the NMR spectrum, we can deduce the connectivity of atoms in the molecule and determine the sequence of the oligosaccharide or polysaccharide.

Section 2: Using CASPER for NMR Data Analysis

2.1 What is CASPER?
CASPER is a computer program designed for the structure elucidation of oligo- and polysaccharides using NMR data. It uses a combination of chemical knowledge and statistical analysis to predict the most likely structure of the molecule based on the observed NMR data.

2.2 How does CASPER work?
CASPER works by simulating the NMR spectrum of a given molecule and comparing it to the experimental spectrum obtained from the sample. It takes into account the chemical shifts, coupling constants, and other parameters that influence the NMR spectrum, and uses these values to predict the most likely structure of the molecule.

2.3 What is the novel Web-based version of CASPER?
The novel Web-based version of CASPER allows users to upload their NMR data and perform structure elucidation directly from their web browser. This eliminates the need for downloading and installing software on their computer, making it more accessible to a wider range of users.

Section 3: Practical Examples

3.1 Calculate the 13C chemical shifts for the following structure:

CH2OH

3.2 Compare the calculated 13C chemical shifts with the experimental data obtained from a sample of the same structure.

3.3 Use CASPER to determine the structure of the following oligosaccharide:

HOCH2(CH2)6OSO3H

Conclusion:
In this lesson, we have learned about NMR spectroscopy and its application in determining the sequence of oligosaccharides and polysaccharides. We have also learned about the novel Web-based version of the computer program CASPER, which simplifies the process of structure elucidation using NMR data. By using CASPER, we can accurately predict the structure of oligosaccharides and polysaccharides, providing valuable insights into their function and role in biological systems.
