In an ene-thiol based photocurable resin composition which is a radical polymerization type photocuring system, active thiyl radicals are regenerated even when radicals are deactivated by oxygen. Said composition therefore has advantages such that polymerization inhibition caused by oxygen that occurs in acrylic materials does not occur, that the used amount of a photopolymerization initiator can be reduced, that volume shrinkage at the time of curing can be reduced, that curing can be done in a short period of time, i.e., from a few seconds to a few minutes after the initiation of polymerization, and that cured products of thick-film having a thickness of 1 mm or more can be produced, and is gathering attention as a photocurable material (Non-Patent Document 1).
For example, Patent Document 1 discloses a photocurable resin composition comprising polyene, polythiol and a compound having a bromine-substituted aromatic ring having a specific structure, in which the mass ratio of the polyene to the polythiol is from 49:1 to 1:49, as such an ene-thiol-based photocurable resin composition. Also, Patent Document 2 discloses an ene-thiol-based photocurable resin composition comprising a polyene compound, and a (poly)thiol-based monomer consisting of a reaction product of a polyvalent amine compound and a mercaptocarboxylic acid compound.
The technology disclosed in Patent Document 1 provides a photocurable resin composition having a high refractive index, in which the refractive index can be adjusted with high precision. The technology disclosed in Patent Document 2 provides a cured product that can be cured in a short period of time without polymerization inhibition caused by oxygen and with reduced volume shrinkage, and in which the amount of a photopolymerization initiator used can be reduced and humidity resistance is notably improved. However, Patent Documents 1 and 2 do not in any way mention the shock absorption and vibration absorption of the cured product.
Patent Document 3 discloses a transparent resin consisting of a cured product of a polymerizable composition comprising at least one of diallyl phthalate, diallyl isophthalate and diallyl terephthalate, and pentaerythritol tetra(3-mercaptopropionate). However, the concept of the shock properties described in Patent Document 3 which concern penetration of a ball and scattering of a sample is close to that of toughness and elongation properties, which are different from shock absorption in terms of rebound properties. Also, there is no mention of turbidity (haze) and yellowing (b* value) which indicate transparency.

Q:

Inserting values with arcpy.da.InsertCursor()?

Building on Standalone Python script to split a polyline with a point layer, I don't think I am manipulating geometry objects correctly.  I am splitting an original line, preserving all the attribution, and inserting new lines with the original attribution but updated geometry.
import arcpy

mxd = arcpy.mapping.MapDocument("CURRENT")
layers = ["Primary OH Conductor", "Transformer Bank"]
line_lyr = layers[0]
point_lyr = layers[1]
points = [row[0] for row in arcpy.da.SearchCursor(point_lyr, "SHAPE@")]

line_fields = []
line_fields.append("SHAPE@")

try: arcpy.Delete_management("lines")
except: pass
arcpy.MakeFeatureLayer_management(line_lyr,"lines")
for rec in "lines":
    with arcpy.da.SearchCursor(in_table = "lines",
                               field_names = line_fields) as o_search_cur:
        feature_values = []
        for row in o_search_cur:
            feature_values.append(row)
            line = row[-1]
    for point in points:
        if line.distanceTo(point) < 0.001:
            snappoint = line.snapToLine(point).firstPoint
            if not (snappoint.equals(line.lastPoint) and snappoint.equals(line.firstPoint)):
                cutline1, cutline2 = line.cut(arcpy.Polyline(arcpy.Array([arcpy.Point(snappoint.X+10.0, snappoint.Y+10.0),
                                                                          arcpy.Point(snappoint.X-10.0, snappoint.Y-10.0)]),

Lesson: Manipulating Geometry Objects in ArcGIS Using Python

## Section 1: Introduction

Manipulating geometry objects in ArcGIS using Python is a powerful skill that can help you automate tasks, create custom tools, and analyze data more efficiently. In this lesson, we will learn how to split a polyline with a point layer using the InsertCursor method from the arcpy.da module. We will also learn about the SearchCursor method, which allows us to search for features based on certain criteria.

## Section 2: Background Knowledge

Before we dive into the code, let's first understand some basic concepts related to geometry objects in ArcGIS. A geometry object is a representation of a physical feature on the Earth's surface, such as a line, polygon, or point. These objects are stored in a geodatabase and can be accessed using various programming languages, including Python.

The InsertCursor method is used to insert new rows into a table based on the results of a search cursor. The SearchCursor method returns a cursor that can be used to search for features based on certain criteria, such as attribute values or spatial locations.

## Section 3: Practical Examples

Now that we have some background knowledge, let's look at an example of how to split a polyline with a point layer using Python. We will use the following steps:

1. Import the necessary modules.
2. Load the map document.
3. Define the layers we want to work with.
4. Create a cursor to search for points.
5. Define the fields we want to update.
6. Loop through each feature in the line layer.
7. Use the SearchCursor method to find the nearest point to the line.
8. Update the geometry of the line based on the nearest point.
9. Insert the updated line into a new table.

Here is the code for the above steps:

```python
import arcpy

mxd = arcpy.mapping.MapDocument("CURRENT")
layers = ["Primary OH Conductor", "Transformer Bank"]
line_lyr = layers[0]
point_lyr = layers[1]
points = [row[0] for row in arcpy.da.SearchCursor(point_lyr, "SHAPE@")]

line_fields = []
line_fields.append("SHAPE@")

try: arcpy.Delete_management("lines")
except: pass
arcpy.MakeFeatureLayer_management(line_lyr,"lines")
for rec in "lines":
    with arcpy.da.SearchCursor(in_table = "lines",
                               field_names = line_fields) as o_search_cur:
        feature_values = []
        for row in o_search_cur:
            feature_values.append(row)
            line = row[-1]
    for point in points:
        nearest_point = None
        min_distance = float('inf')
        for p in points:
            if p != point and p != nearest_point:
                dist = arcpy.geometry.PointToPointDistance(p, (point[0], point[1]))
                if dist < min_distance:
                    min_distance = dist
                    nearest_point = p
        if nearest_point:
            start_pt = line.StartPoint
            end_pt = line.EndPoint
            near_pt = nearest_point
            if start_pt == near_pt:
                line_new = line.Reverse()
            else:
                line_new = line
            line_new.StartPoint = near_pt
            line_new.EndPoint = near_pt
            arcpy.AddMessage("Updated line: " + str(line_new))
            arcpy.CreateFeature_management("lines", line_new, "line")
```

## Section 4: Glossary

text: In a follow up to our original post on the CryEngine 2 for architectural visualisation we have a movie update:. Of note is the realtime ambient maps demo – we know that criticism of 3D Max is frowned upon in many circles but can you imagine how long such a scene would take to render? To be able to do this in realtime via a game engine is enticing and it makes us wonder why more 3D modelling software, such as 3DMax, don’t have better realtime tools built in.. To see more on this and our realtime Oblivion movies take a look at the Game Engine Thread.. One Comment. OK.. Very compliment to Crytek for the demo. It is a very good example.. When a war would be needed… we’ll choose their software. I hope nobody wants to apply what showed.. I suggest Crytek to drop that video and to insert, instead, a more quiet images, showing a WindMill for electric power production, for the peace.. Best regards. BobMaX

Q:

Using python, what's the fastest way to see which of around one million ip addresses fit into three cidrs?

I have a list of ~1,000,000 ip address strings. I want to get the set of these ip addresses that are in  three cidrs (each cidr is a string like this: "1.0.0.0/25"). What is the fastest way to do this?
A) Convert the three cidrs into sets containing all ip addresses contained in the cidrs. For each ip address in my list, I check if the ip address is in the wanted ip address set.
B) Convert each cidr into min & max ip address. Convert each ip address into a tuple of ints and check if ip > min and ip < max.

A:

If you're on Python 3.3 or higher, a decent solution is to use the ipaddress module. Convert your CIDRs to network objects with ipaddress.ip_network up front, then convert your addresses to address objects (with ipaddress.ip_address if they might be IPv4 or IPv6, or just ipaddress.IPv4Address/ipaddress.IPv6Address directly if they are of known type (skips a layer of wrapping).
You can test for membership relatively cheaply with the in operator, e.g. if you stored your networks in a sequence (e.g. list/tuple) you could do:
for address in map(ipaddress.ip_address, stream_of_string_addresses):
    if any(address in network for network in networks):
        ... got a match ...

There are more efficient solutions (particularly if you're talking about many networks, not just three), but this is straightforward, relatively memory efficient, and leaves you with a useful object (not just the raw address string) for further processing.

textbook:
for address in str(address) for network in networks:
    if address in network:
        print(address)

This will print out all the IP addresses that fall within the three CIDRs.

Here's the step-by-step process:

1. Import the necessary modules
```python
import ipaddress
```

2. Define the CIDRs as network objects
```python
networks = [ipaddress.ip_network("1.0.0.0/25"),
            ipaddress.ip_network("2.0.0.0/25"),
            ipaddress.ip_network("3.0.0.0/25")]
```

3. Convert the IP addresses to address objects
```python
addresses = [ipaddress.ip_address(ip_address) for ip_address in ip_addresses]
```

4. Check for membership in the networks
```python
for address in addresses:
    for network in networks:
        if address in network:
            print(address)
```

Note that this solution assumes that all IP addresses are IPv4. If there are any IPv6 addresses in the list, you'll need to handle them separately. Also, you may want to add some error handling to deal with any invalid IP addresses in the input list.

Guest reviews are written by people who have stayed at the hotel. They provide personal experiences and opinions about their stay, including the quality of service, cleanliness, location, and overall value for money.

Expert reviews, on the other hand, are written by professional reviewers who evaluate hotels based on specific criteria, such as design, amenities, and location. These reviews are usually more detailed and objective than guest reviews.

Section 2: Reading Hotel Reviews

2.1. Understanding the language

When reading hotel reviews, it is essential to understand the language used by reviewers. Here are some common terms used in hotel reviews:

- Cleanliness: This refers to the overall cleanliness of the room and public areas of the hotel.
- Service: This refers to the quality of service provided by hotel staff, such as receptionists, waiters, and housekeeping.
- Location: This refers to the hotel's proximity to nearby attractions, transportation, and other facilities.
- Value for money: This refers to whether the hotel offers good value for the price paid.

2.2. Reading between the lines

When reading hotel reviews, it is essential to read between the lines and understand the reviewer's tone. For example, a negative review may not necessarily mean that the hotel is bad, but rather that the reviewer had unrealistic expectations or encountered a minor issue during their stay.

Section 3: Analyzing Hotel Reviews

3.1. Identifying patterns

To analyze hotel reviews effectively, it is essential to identify patterns in the data. For example, if many reviews mention poor service or dirty rooms, this may indicate a recurring problem at the hotel.

3.2. Comparing reviews

Comparing reviews from different sources can provide a more accurate picture of the hotel's quality. For example, if a hotel has mostly positive reviews on TripAdvisor but negative reviews on Expedia, this may suggest that the hotel has a mixed reputation.

Section 4: Conclusion

In conclusion, reading and understanding hotel reviews is an essential skill for any traveler. By analyzing the language used, reading between the lines, and comparing reviews from different sources, you can gain valuable insights into the quality of service, cleanliness, location, and overall value for money at a particular hotel. This information can help you make informed decisions about where to stay during your travels.

Lesson: How to Sell Your Home to Break Even After Factoring All Potential Costs
Introduction:
Selling your home can be a daunting task, especially if you're not sure how to go about it. In this lesson, we will cover the steps you need to take to sell your home and break even after factoring all potential costs. We will also discuss the importance of working with a real estate agent and the benefits of staging your home before putting it on the market.
Section 1: Preparing to Sell Your Home
- Research the current market value of your home: Before putting your home on the market, you need to research the current market value of your home. You can do this by looking at similar homes in your area that have sold recently or by hiring a professional appraiser.
- Determine your selling price: Once you know the current market value of your home, you can determine your selling price. Remember to factor in any repairs or upgrades you've made to your home that could increase its value.
- Work with a real estate agent: A real estate agent can help you navigate the complex world of selling a home. They can provide valuable insights into the local market and help you negotiate with potential buyers.
Section 2: Staging Your Home
- Declutter your home: One of the most important things you can do to stage your home is to declutter it. Remove any unnecessary items from your home and pack away any personal belongings that aren't necessary.
- Make necessary repairs: Before putting your home on the market, make any necessary repairs. This includes fixing any leaky faucets, patching holes in the walls, or replacing broken fixtures.
- Add curb appeal: The outside of your home is just as important as the inside. Make sure your lawn is mowed, your flowers are blooming, and your front door is clean and welcoming.
Section 3: Selling Your Home
- Choose a realistic selling price: Once you've prepared your home and worked with a real estate agent, it's time to choose a selling price. Remember to be realistic and consider the current market value of your home.
- Market your home: Your real estate agent will help you market your home by listing it on the Multiple Listing Service (MLS) and other online real estate websites.
- Negotiate with potential buyers: Once you've received an offer, it's time to negotiate with potential buyers. Your real estate agent will help you understand the offer and negotiate on your behalf.
Conclusion:
Selling your home can be a challenging process, but by preparing your home, working with a real estate agent, and negotiating with potential buyers, you can sell your home and break even after factoring all potential costs. Remember to be patient and take your time when selling your home to ensure you get the best possible price.

# Lesson: Understanding the UsbSerialDiscoveryListener Interface

## Introduction

The UsbSerialDiscoveryListener interface is used to listen for changes in the USB serial ports connected to a device. This interface is particularly useful for devices that need to communicate with other devices via serial ports. In this lesson, we will learn about the methods in the UsbSerialDiscoveryListener interface and how they can be used to detect changes in the USB serial ports.

## Methods in the UsbSerialDiscoveryListener Interface

The UsbSerialDiscoveryListener interface has two methods: `usbSerialDeviceDiscovered()` and `usbSerialDeviceRemoved()`. These methods are called when a new serial port is discovered or when an existing serial port is removed, respectively.

### `usbSerialDeviceDiscovered()`

The `usbSerialDeviceDiscovered()` method is called when a new serial port provided by a USB device is discovered. The `UsbSerialDeviceInformation` parameter contains information about the newly discovered serial port, such as its name, description, and location.

### `usbSerialDeviceRemoved()`

The `usbSerialDeviceRemoved()` method is called when a serial port provided by a USB device has been removed. The `UsbSerialDeviceInform` parameter contains information about the removed serial port, such as its name and location.

## Conclusion

In this lesson, we learned about the UsbSerialDiscoveryListener interface and its two methods: `usbSerialDeviceDiscovered()` and `usbSerialDeviceRemoved()`. We also learned about the parameters passed to these methods and how they can be used to detect changes in the USB serial ports. By understanding this interface, developers can create applications that can communicate with other devices via serial ports.

Mu, delta, and kappa opioid receptor agonists induce peripheral antinociception by activation of endogenous noradrenergic system.
Opioid receptor agonists induce noradrenaline release in the supraspinal, spinal, and peripheral sites. Endogenous noradrenaline release can induce an antinociceptive effect by activation of the α(2) adrenoceptor. This interaction between the opioid and the adrenergic systems could be the alternative mechanism by which opioid receptor agonists mediate peripheral antinociception. Therefore, the aim of the present study was to verify whether peripheral antinociception induced by the μ, δ, and κ opioid receptor agonists DAMGO, SNC80, and bremazocine, respectively, through the endogenous noradrenergic system. All drugs were administered locally into the right hind paw of male Wistar rats. The rat paw pressure test was used, with hyperalgesia induced by intraplantar injection of prostaglandin E(2). DAMGO, SNC80, or bremazocine elicited local dose-dependent peripheral antinociception. This peripheral effect was antagonized by the nonselective α(2) adrenoceptor antagonist yohimbine and by the selective α(2C) adrenoceptor antagonist rauwolscine but not by the selective antagonists for α(2A), α(2B), and α(2D) adrenoceptor subtypes (BRL 44 480, imiloxan, and RX 821002, respectively). The opioid-induced effect was antagonized by the nonselective α(1) adrenoceptor antagonist prazosin and by the nonselective β adrenoceptor antagonist propranolol. Guanethidine, a depletor of peripheral sympathomimetic amines, restored approximately 50-60% of the opioid-induced peripheral antinociception. Furthermore, acute injection of the noradrenaline reuptake inhibitor reboxetine intensified the antinociceptive effects of low-dose DAMGO, SNC80, or bremazocine. This study provides evidence that DAMGO, SNC80, or bremazocine induces peripheral antinociception by noradrenaline release and interaction with adrenoceptors.

Lesson: Opioid Receptors and Pain Relief

Introduction:
Opioid receptors are found throughout the body and play a crucial role in pain relief. They are involved in the perception of pain and the body's response to it. In this lesson, we will learn about the different types of opioid receptors, how they work, and their role in pain relief.

Core Value:
The core value of this lesson is that opioid receptors are essential for pain relief and that there are different types of these receptors that work together to help reduce pain.

Section 1: Types of Opioid Receptors
There are three main types of opioid receptors: mu, delta, and kappa. Each type has a unique structure and function, but they all work together to help reduce pain.

1. Mu opioid receptors: These receptors are the most common and are found throughout the body. They are responsible for the majority of the pain-relieving effects of opioids.

2. Delta opioid receptors: These receptors are less common than mu receptors but are still important. They are primarily found in the brain and spinal cord.

3. Kappa opioid receptors: These receptors are the least common and are also found mainly in the brain. They have a more complex role in pain relief and are involved in both pain relief and other functions.

Section 2: How Opioid Receptors Work
Opioid receptors work by binding to a substance called endorphin. Endorphins are natural painkillers produced by the body. When an opioid receptor binds to endorphin, it triggers a series of events that ultimately lead to pain relief.

Section 3: Opioid Receptors and Pain Relief
Opioid receptors play a crucial role in pain relief. When an opioid drug is taken, it binds to the mu, delta, and kappa opioid receptors in the body. This binding activates the endogenous noradrenergic system, which releases noradrenaline. Noradrenaline then binds to the alpha-2 adrenergic receptor, which helps to reduce pain.

Section 4: Practical Examples
One practical example of how opioid receptors work is in the treatment of chronic pain. Morphine, a powerful opioid drug, can be used to help manage pain in people with conditions such as cancer or multiple sclerosis. By binding to the mu opioid receptors in the body, morphine can help reduce pain and improve the patient's quality of life.

Conclusion:
In conclusion, opioid receptors are essential for pain relief, and there are different types of these receptors that work together to help reduce pain. Understanding how these receptors work can help us better understand the mechanisms behind pain relief and how to use opioid drugs effectively to manage pain.
