Q:

What does it mean by “end effects can be ignored”

I have been reading a book ( Statistics for Biology and Health) and i encountered many of following bold text.

Consider a long DNA sequence of length N, where N is assumed to be
so large that end effects can be ignored in our calculations.

In Shotgun sequencing also the saw similar thing :

The fragments are assumed to be taken at random from the original
full-length sequence, so that if end effects are ignored, the left-hand ends
of the fragments are independently distributed with a common uniform
distribution over [0,G].

What does " end effects can be ignored " means?

A:

They are considering a model of a DNA sequence of quasi infinite size. They consider a case where the DNA sequence is so long that the fact that it has ends will only negligibly affect the conclusions of their model. This is likely the same as considering the DNA is circular.
To give you a similar logic, imagine a species where individuals live in different populations. All population can be placed on a one dimensional axis. The migration rate from one population to the neighbouring population is 0.1 (this is called a "stepping stone model" btw). Hence, the probability of not migrating is 0.8 (1 - 0.1 - 0.1). I can draw conclusions from such a model but it would be important to specify that I neglected the end effects and hence, I assumed there are a lot of populations (or that the population form a loop). Why did I neglect the end effects. The last population on each side cannot have a migration rate of 0.1 toward a population that does not exist. Hence, their migration rate must differ from the other populations. This is commonly called edge effects (rather than "end effects")

Lesson: Understanding the Effects of Sequence Length on Biological Data Analysis

Introduction:

In biology, sequence data is often analyzed to understand the structure, function, and evolution of molecules such as DNA, RNA, and proteins. However, when dealing with very long sequences, it is sometimes assumed that "end effects can be ignored." In this lesson, we will explore what this means and how it impacts biological data analysis.

Section 1: Understanding the Concept

Topic 1: What are end effects in sequence analysis?

End effects refer to the impact that the presence or absence of specific nucleotides at the ends of a DNA sequence can have on the analysis of that sequence. These effects can be due to technical limitations in the sequencing process, such as the inability to fully sequence the ends of a molecule.

Topic 2: Why would someone want to ignore end effects?

When dealing with very long sequences, such as entire genomes or large portions of them, the impact of end effects on the analysis may be negligible. Ignoring these effects can simplify the analysis and make it more computationally efficient.

Section 2: Exploring the Implications

Topic 3: How do end effects impact sequence analysis?

End effects can impact sequence analysis in several ways. For example, they can cause errors in the alignment of related sequences, leading to incorrect inferences about their evolutionary relationships. Additionally, end effects can impact the estimation of genome-wide properties, such as GC content or dinucleotide frequency.

Topic 4: How can end effects be addressed?

There are several methods for addressing end effects in sequence analysis. One approach is to use a computational method called "truncated sequence alignment" which ignores the ends of the sequences being compared. Another approach is to use experimental techniques that allow for the full sequencing of the ends of molecules, such as mate-pair sequencing.

Section 3: Practical Applications

Topic 5: Example of end effects in a real-world scenario

An example of end effects can be seen in the analysis of transposable elements in the human genome. Transposable elements are mobile pieces of DNA that can move within the genome, and their presence and movement can have significant impacts on gene regulation and function. However, due to end effects, the accurate detection and classification of these elements can be challenging.

Conclusion:

In this lesson, we have explored the concept of end effects in sequence analysis and their implications for biological data analysis. We have discussed how these effects can be addressed and provided an example of their impact on real-world research. By understanding these effects, researchers can improve the accuracy and reliability of their analyses and draw more meaningful conclusions from their data.

Lesson: Measles Outbreak Prevention

Introduction:
Measles is a highly contagious disease that can cause severe health complications, especially in young children and pregnant women. In this lesson, we will learn about the symptoms, prevention, and treatment of measles.

Section 1: What is Measles?
Measles is an infectious respiratory illness caused by the measles virus. It spreads easily through the air when an infected person coughs or sneezes. It is one of the most contagious viruses, with a rate of transmission of up to 90%.

Symptoms:
- Fever
- Cough
- Runny nose or red eyes
- Red blotchy rash that appears three to seven days after fever starts
- The rash typically begins behind the ears and on the face, spreading down to the body, and finally to the arms and legs

Prevention:
The best way to prevent measles is through vaccination. The measles, mumps, and rubella (MMR) vaccine is highly effective in preventing measles. It is recommended that children receive two doses of the MMR vaccine, starting with the first dose at 12-15 months of age, and the second dose at 4-6 years of age.

Treatment:
There is no cure for measles, but it can be prevented with vaccination. Treatment focuses on managing symptoms and preventing complications. Over-the-counter medications can be used to reduce fever and relieve pain. In severe cases, hospitalization may be necessary for fluids and nutrition.

Section 2: How to Prevent Measles Outbreaks

1. Vaccination: Ensure that you and your family members are up-to-date on their MMR vaccinations. If you are unsure, consult with your healthcare provider.

2. Hygiene: Wash your hands regularly and avoid touching your face, especially your eyes, nose, and mouth. Cover your mouth and nose when you sneeze or cough.

3. Avoid close contact: Stay away from people who are sick or showing symptoms of measles. If you are unsure, it is better to err on the side of caution and avoid close contact.

4. Disinfect surfaces: Clean and disinfect frequently touched surfaces, such as doorknobs, light switches, and countertops, to reduce the spread of the virus.

Section 3: Real-World Examples

Scenario 1: A mother has two young children, aged 1 and 3 years old. She is concerned about their risk of getting measles. What can she do to protect them?
Answer: The mother should ensure that her children are up-to-date on their MMR vaccinations. If they are not yet eligible for vaccination, she should take extra precautions to avoid close contact with individuals who may be infected with measles. She should also practice good hand hygiene and disinfect frequently touched surfaces in her home.

Scenario 2: A daycare center has several children who are not vaccinated against measles. How can the staff prevent an outbreak?
Answer: The staff should take extra precautions to ensure that the children are not exposed to individuals who may be infected with measles. They should also practice good hand hygiene and disinfect frequently touched surfaces in the daycare center. Additionally, they should monitor the children for any signs of measles and report any suspicious cases to the health department.

Conclusion:
Measles is a highly contagious disease that can cause severe health complications. By understanding the symptoms, prevention, and treatment of measles, we can take steps to prevent outbreaks and protect ourselves and our communities. Remember to stay up-to-date on vaccinations, practice good hygiene, and avoid close contact with individuals who may be infected with measles.

Glossary:
- Measles: An infectious respiratory illness caused by the measles virus
- Vaccination: The process of introducing a vaccine into the body to stimulate immunity to a specific disease
- MMR vaccine: A vaccine that protects against measles, mumps, and rubella
- Outbreak: An occurrence of disease in a community or region higher than expected
- Complication: A secondary medical problem that is caused by or related to a primary condition or disease

Self-Debate:
- Should I be concerned about measles if I have been vaccinated?
- Yes, while vaccination is highly effective in preventing measles, there is still a small chance that you could contract the disease. However, if you do get measles, your symptoms are likely to be milder and your risk of complications is lower.

Do changes in antimicrobial resistance necessitate reconsideration of surgical antimicrobial prophylaxis strategies?
The potential need for re-evaluation of guidelines on surgical antimicrobial prophylaxis (AMP) in an era of advancing antimicrobial resistance is a matter of a considerable controversy. Review of the pertinent literature. Over the last decade, the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) has increased significantly, as illustrated by several surveillance studies. The blending of community acquisition and long-term carriage may increase the probability of unrecognized MRSA carriers being admitted to the hospital. Thus, MRSA is considered a major epidemiological threat in most parts of the world, exerting pressure for reconsideration of the guidelines for surgical AMP. The use of a glycopeptide as first-choice prophylaxis in major procedures such as cardiac surgery generally is not recommended but is not ruled out. Current recommendations are based on trials performed almost a decade ago at the latest and do not reflect the contemporary epidemiology of resistance. A few recent studies suggested that vancomycin in combination with gentamicin and rifampicin reduces the incidence of surgical site infections significantly in high-risk patients. These developments led some surgeons and infectious diseases clinicians to consider advanced antimicrobial coverage in surgical AMP. On the other hand, other clinicians are rightfully skeptical about extensive administration of glycopeptides or other agents beyond first- or second-generation cephalosporins because of the risk of further emergence and dissemination of antimicrobial resistance. Properly designed randomized trials are needed urgently to determine whether standard perioperative AMP should be reconsidered in settings with changing etiology of surgical infections.

Lesson Title: Antimicrobial Resistance and Surgical Antimicrobial Prophylaxis Strategies

Introduction:
Antimicrobial resistance is a global health concern that has been recognized by the World Health Organization (WHO). It occurs when microorganisms evolve and adapt to the use of antimicrobial drugs, rendering them ineffective. This has led to the need for reconsideration of surgical antimicrobial prophylaxis (AMP) strategies. In this lesson, we will explore the importance of AMP, the impact of antimicrobial resistance on AMP, and the potential changes that may be necessary in AMP strategies.

Section 1: What is Antimicrobial Resistance?
Antimicrobial resistance occurs when microorganisms, such as bacteria, viruses, and fungi, develop the ability to resist the effects of antimicrobial drugs. This can occur through genetic mutations, gene transfer, or other mechanisms. When antimicrobial resistance occurs, the effectiveness of antimicrobial drugs is reduced, making it more difficult to treat infections.

Section 2: Why is Surgical Antimicrobial Prophylaxis Important?
Surgical AMP is the practice of administering antimicrobial drugs to patients before surgery to prevent surgical site infections (SSIs). SSIs are a significant cause of morbidity and mortality, and they increase healthcare costs. By implementing AMP strategies, healthcare providers can reduce the risk of SSIs and improve patient outcomes.

Section 3: The Impact of Antimicrobial Resistance on Surgical Antimicrobial Prophylaxis
As antimicrobial resistance continues to rise, it becomes more challenging to treat infections effectively. This has implications for AMP strategies, as some antimicrobial drugs may no longer be effective in preventing SSIs. Additionally, the overuse of certain antimicrobial drugs can contribute to the development of resistance, further complicating AMP strategies.

Section 4: Potential Changes in Surgical Antimicrobial Prophylaxis Strategies
In light of the growing concern over antimicrobial resistance, several changes may be necessary in AMP strategies. These changes include:

1. Using broader-spectrum antimicrobial drugs when appropriate to cover a wider range of potential pathogens.
2. Implementing targeted AMP strategies that use specific antimicrobial drugs based on the patient's risk factors and the anticipated pathogens.
3. Utilizing diagnostic tests to identify the specific pathogen before administering antimicrobial drugs.
4. Limiting the use of antimicrobial drugs to situations where they are truly needed to reduce the development of resistance.
5. Educating healthcare providers and patients about the importance of appropriate antimicrobial drug use and infection prevention measures.

Conclusion:
In conclusion, antimicrobial resistance is a significant concern that affects the effectiveness of antimicrobial drugs, including those used in surgical antimicrobial prophylaxis. As a result, changes in AMP strategies may be necessary to combat the rise in antimicrobial resistance. By implementing targeted, evidence-based AMP strategies, healthcare providers can reduce the risk of surgical site infections and improve patient outcomes.

Glossary:
- Antimicrobial resistance: The ability of microorganisms to resist the effects of antimicrobial drugs
- Surgical antimicrobial prophylaxis (AMP): The practice of administering antimicrobial drugs to patients before surgery to prevent surgical site infections
- Antimicrobial drugs: Medications used to treat infections caused by bacteria, viruses, and fungi
- Surgical site infections (SSIs): Infections that occur at the site of a surgical procedure

Lecture Points To Emerging Bacterial Resistance To Silver

At the recently concluded scientific sessions of the American Professional Wound Care Association (APWCA), Adrianne P.S. Smith, MD, presented evidence of evolving bacterial resistance to silver.

Silver dressings are, of course, frequently utilized in wound care. It has been generally accepted that natural resistance to silver does not occur. However, Dr. Smith noted that silver resistance is being increasingly reported. The origins of this resistance include: plasmids with encoded genes for silver resistance; bacterial chromosomes; and selection when too low a dosage of silver exposure allows bacterial survival.

Dr. Smith reported that Klebsiella sp., E. Coli, Pseudomonas stutzeri, and Acinetobacter baumannii were among bacterial species that have already demonstrated silver resistance. She noted that bacterial tolerance to silver could result from extended exposure to silver in addition to inadequate concentration or too slow a release of silver into the wound. Dr. Smith noted that debridement to remove biofilms and enhance wound healing increases the effectiveness of silver in general.

Dr. Smith further noted that copper alloy may be the next popular metallic bactericidal agent. She noted that the Environmental Protection Agency (EPA) has approved copper antibacterial agents and pointed out that copper alloy surfaces eliminate 99.9 percent of all bacteria, including MRSA, within two hours. In addition, she noted that copper resistance has already been reported.

Dr. Smith is President and Medical Consultant for the Wound Professional Services of San Antonio.

Lesson: Understanding Bacterial Resistance to Silver

Introduction:
In this lesson, we will learn about bacterial resistance to silver and its implications in wound care. We will cover the following topics:

1. What is bacterial resistance?
2. How does bacterial resistance to silver occur?
3. Why is it important to understand bacterial resistance to silver?
4. How can we prevent and manage bacterial resistance to silver?

Section 1: What is bacterial resistance?

Bacterial resistance refers to the ability of bacteria to survive and grow in the presence of antimicrobial agents such as antibiotics or silver. This occurs through various mechanisms, including genetic mutations, gene transfer, and selection pressure.

Section 2: How does bacterial resistance to silver occur?

Bacterial resistance to silver occurs through several mechanisms, including:

1. Plasmids with encoded genes for silver resistance: Some bacteria carry plasmids, which are small, circular pieces of DNA that can be transferred between bacteria. These plasmids may contain genes that provide resistance to silver.

2. Bacterial chromosomes: Some bacteria have genes on their chromosomes that provide resistance to silver. When these bacteria reproduce, they pass on these resistant genes to their offspring.

3. Selection pressure: When bacteria are exposed to a low dose of silver, some may survive and reproduce. Over time, this can lead to an increase in the number of silver-resistant bacteria in the population.

Section 3: Why is it important to understand bacterial resistance to silver?

Understanding bacterial resistance to silver is important for several reasons:

1. It helps us to develop more effective treatments for wounds. If we know how bacteria become resistant to silver, we can design treatments that are less likely to promote resistance.

2. It helps us to monitor and control the spread of resistant bacteria. By understanding how bacteria become resistant to silver, we can develop strategies to track the spread of these resistant strains and limit their transmission.

3. It helps us to make informed decisions about the use of silver in wound care. Knowing about the risks of bacterial resistance to silver can help us to choose the most appropriate treatment options for our patients.

Section 4: How can we prevent and manage bacterial resistance to silver?

There are several steps we can take to prevent and manage bacterial resistance to silver:

1. Use antimicrobial agents judiciously: Overuse of antimicrobial agents can contribute to the development of resistance. We should only use these agents when necessary and follow the recommended guidelines for their use.

2. Use silver in appropriate concentrations: Too low a dosage of silver exposure can allow bacterial survival, leading to resistance. We should ensure that we use the appropriate concentration of silver in wound care treatments.

3. Monitor and track the spread of resistant bacteria: By tracking the spread of resistant bacteria, we can identify outbreaks and take steps to prevent their transmission.

4. Educate patients and healthcare providers: Patients and healthcare providers should be educated about the risks of bacterial resistance to silver and the importance of using these treatments appropriately.

Conclusion:

Understanding bacterial resistance to silver is crucial for the development of effective wound care treatments and the prevention of the spread of resistant bacteria. By following the guidelines outlined above, we can help to minimize the risk of bacterial resistance to silver and improve patient outcomes.

Francisco Boix

Francesc Boix i Campo (in Spanish Francisco Boix Campo, 31 August 1920 in Barcelona – 7 July 1951 in Paris) was a veteran of the Spanish Civil War and photographer who was imprisoned in the Mauthausen concentration camp. At the Nuremberg and Dachau trials he presented photographs that played a role in the conviction of Nazi war criminals.

Biography
As a Spanish republican he was exiled in France in 1939. He was recruited by the French Foreign Legion and French Army and captured in 1940 by the Germans. Boix, like over 7,000 Spaniards, was an inmate in the Mauthausen concentration camp between January 1941 and May 1945. From the end of August 1941 he worked in the Erkennungsdienst, the photography department of the camp administration, taking ID photos of inmates and documenting events in the camp. He was able to hide and preserve until liberation about 20,000 negatives taken by the SS head of the department, Paul Ricken, as well as by himself.

On January 28 and 29, 1946 at the Nuremberg trial (International Military Tribunal), Boix was called by the French prosecution to show photographs taken by the SS in Mauthausen. Those photos depicted the conditions in which the prisoners lived and were murdered in that camp. They were also proof that the camp was known and visited by high leaders of the Third Reich, such as Ernst Kaltenbrunner, who appeared visiting both the Mauthausen camp proper, and the Wienergraben quarry adjacent to the camp.

In April 1946 Boix was again a witness, this time in the American military trial that took place in Dachau against 61 accused from the Mauthausen camp.

Between 1945 and 1951 Boix worked as a photo reporter in the French press, particularly for a newspaper associated with the French Communist Party.

He died in Paris on 7 July 1951 from kidney failure at age 30.

Lesson: Understanding Health Coverage Through the U.S. Chamber of Commerce

Introduction:
The U.S. Chamber of Commerce is an organization that represents the interests of businesses in the United States. One of the services they provide is a directory of Association Health Plans (AHPs) that small businesses, working owners, and companies can use to find health coverage options. In this lesson, we will explore what AHPs are, how they work, and how the Chamber's directory can help you find the right health coverage for your needs.

What are Association Health Plans (AHPs)?
Association Health Plans (AHPs) are group health insurance plans that are sponsored by trade associations, chambers of commerce, or other organizations. These plans are designed to provide affordable health coverage to small businesses and their employees.

How do AHPs work?
AHPs work by pooling the risks of all the members of the association. This means that the healthy members of the group help to subsidize the costs of the less healthy members. By doing this, AHPs can offer lower premiums and higher benefits than individual health insurance policies.

Why use the Chamber's directory to find AHPs?
The U.S. Chamber of Commerce has partnered with insurance carriers to provide a directory of AHPs that are available to small businesses, working owners, and companies. Using this directory, you can easily search for AHPs that operate within your industry and/or geographic area. This makes it easy for you to find health coverage options that meet your specific needs.

How do I use the Chamber's directory?
To use the Chamber's directory, you will need to go to the Chamber's website and click on the "Health Coverage" tab. From there, you will be able to search for AHPs by industry and/or geographic area. Once you have found a plan that meets your needs, you will need to contact the insurance carrier directly to enroll in the plan.

Conclusion:
In conclusion, understanding health coverage through the U.S. Chamber of Commerce's directory of Association Health Plans can help you find affordable and comprehensive health coverage options. By using this directory, you can easily search for AHPs that operate within your industry and/or geographic area, making it easy for you to find health coverage options that meet your specific needs. With the knowledge and skills gained from this lesson, you can now apply these to new problems and make informed decisions about your health coverage options.

Lesson: Introduction to International Trade

### Section 1: What is International Trade?
International trade refers to the exchange of goods, services, and capital between countries. It involves importing and exporting, where countries buy and sell products from other countries to meet their demands and needs. This exchange helps countries to access resources, products, and services that they may not be able to produce themselves.

### Section 2: Why do countries engage in International Trade?
Countries engage in international trade for several reasons. One reason is that it allows them to access resources and products that they may not be able to produce themselves. For example, a country may import oil from another country if it does not have any oil reserves. Another reason is that international trade creates jobs and stimulates economic growth. When countries trade with each other, they create more opportunities for employment and increase their income.

### Section 3: How does International Trade work?
International trade works through a system of agreements and treaties between countries. These agreements set the rules for trade, such as tariffs and quotas, which determine how much a country can import or export. Countries also use a system of trade organizations, such as the World Trade Organization (WTO), to regulate trade and ensure that all countries follow the same rules.

### Section 4: Examples of International Trade
One example of international trade is the import and export of goods. A country may import food from another country if it cannot produce enough food itself. Another example is the trade of services, such as tourism. A country may export its tourism services to another country, allowing visitors to experience its culture and attractions.

### Section 5: Conclusion
International trade is an important part of the global economy. It allows countries to access resources and products that they may not be able to produce themselves, creates jobs, and stimulates economic growth. By understanding the basics of international trade, we can better appreciate its importance and the role it plays in our daily lives.

text: Probably an odd question. But I have a metro 20 (20x8), and the pedaltrain junior (18x12.5). I can't fit everything on a metro 20, but I can fit it all on the Junior. However, the junior is too deep at 12.5 inches and doesn't fit in some cases I use for gigging. Some places we play require quick in and outs, so I try to keep everything tidy. My perfect board would be 18 x 11, and I could probably just make one, or have a flat board made, but I really like the pedaltrain design. I've also considered joining two Nano+ boards together, but I think the total depth of 10 inches might be tight. So, has anybody tried modifying the pedaltrain? Maybe took a row out, re-welded, anything to get an inch and half off the depth? Just curious.

The student terrorist group “Bears for Palestine” caused a near riot at UC Berkeley, in response to a resolution condemning anti-Semitism. Anti-Semitism continues to be a major problem on American college campuses, despite President Trump’s remarkable efforts to protect Jewish students. Attorney General Barr and Secretary of Education Betsy DeVos must take immediate action against the various pro-Palestinian terrorist groups, who are destroying Jewish life on college campuses. It is just a matter of time before a Jewish student is killed on campus.

Pro-Israel, Pro-Palestinian groups clash at UC Berkeley student union meeting

By The Jewish News of Northern California, February 2, 2020:

A meeting of the UC Berkeley student union deteriorated into shouting and threats this week as pro-Israel and pro-Palestinian advocates clashed over a controversial display that pro-Israel students said “glorif[ies] terrorists.”

An estimated 200 people crowded the main chambers of the Associated Students of the University of California for a committee meeting on Feb. 3 that had to be moved from a smaller room after more than 110 people signed up to deliver public comments, said junior Shelby Weiss, a Hillel member and ASUC senator.

At the center of the controversy is a display put up by the group Bears for Palestine, a campus affinity group that seeks to raise awareness of the Palestinian experience and culture.

The display is inside a room designated for student groups in Eshleman Hall, the building where the ASUC student union meets. The Bears for Palestine cubicle is decorated with a string of Palestinian flags, heart cutouts, a green olive and the letters “BFP” in red cellophane, and a row of photos and short biographies of female Palestinian leaders, including militants who targeted Israeli and diaspora Jewish civilians.

They include Rasmea Odeh, a former member of the Popular Front for the Liberation of Palestine, who was alleged to have participated in a 1969 supermarket bombing in Jerusalem that killed two college students, and Leila Khaled, who attempted a number of plane hijackings. including an El Al flight in 1970 that injured a flight attendant.

The biography underneath Khaled’s photo, which shows her holding an AK-47, describes her as “the first Palestinian woman to hijack a plane.”

Milton Zerman, an ASUC senator and member of Tikvah: Students for Israel, introduced a resolution to the senate condemning the display and asking that it be removed or altered.

“The glorification of murderers and attempted murderers merely because their targets were Israeli citizens can be seen as both insulting and threatening to Jewish and Israeli students at UC Berkeley,” the resolution says.

Conflicts between pro-Israel and pro-Palestinian students are nothing new at Cal, but the confrontation over Zerman’s resolution, which must pass the six-member University and External Affairs Committee if it is to move on to the full student senate, raised the pitch of the debate.

Lesson: Understanding Anti-Semitism on College Campuses

Introduction:
Anti-Semitism is the hatred or prejudice against Jews. It has been a major problem on American college campuses for many years. In this lesson, we will learn about the history of anti-Semitism, its manifestations, and ways to combat it.

Section 1: History of Anti-Semitism

Anti-Semitism has a long history that dates back to ancient times. It was first used to describe the persecution of Jews in Europe during the Middle Ages. Since then, it has been used to describe any form of discrimination or prejudice against Jews.

Section 2: Manifestations of Anti-Semitism

Anti-Semitism can take many forms, including verbal harassment, physical violence, and vandalism. It can also manifest itself in the form of propaganda, such as posters and flyers that spread false information about Jews.

Section 3: Combating Anti-Semitism

There are several ways to combat anti-Semitism on college campuses. One way is to educate students about the history of anti-Semitism and its manifestations. Another way is to create a safe space for Jewish students to express their concerns and feelings. Additionally, colleges can implement policies that prohibit hate speech and promote tolerance.

Section 4: Practical Examples

Let's consider a practical example. Suppose a group of pro-Palestinian students put up a display that glorifies terrorists. Jewish students may feel threatened and intimidated by this display. In this case, the Jewish students could report the display to college authorities and demand that it be removed. They could also organize a counter-display that promotes peace and tolerance.

Conclusion:

Only science and technology can address today's challenges: Hamid Ansari

Jammu, Feb 7 IANS | 2 years ago

Vice President Hamid Ansari Friday said that science and technology are indispensable for addressing major contemporary challenges of economic growth and social transformation.

"Science and technology are indispensable for addressing major contemporary challenges of economic growth and social transformation," Ansari said in his valedictory address at the 101st session of the Indian Science Congress at the University of Jammu here.

The influence of science and technology on people's lives in growing everyday, he noted.

"While recent benefits to humanity from science, technology and innovation are unparalleled in the history of the human species, there are instances where the impact has been harmful," he said.

The development of sophisticated weapons of mass destruction based on scientific knowledge has a few times, threatened the very existence of mankind in the last century, he added.

"Weapons created by science have also imposed painful costs on nation-states during the several wars fought since the advent of the 20th century. The destructive powers of these weapons still pose a clear and present danger to humanity," he said.

Quoting Mahatma Gandhi, Ansari added that scientists have a responsibility to mitigate, if not eliminate, the threats posed by excessive "weaponisation of the planet".

"Gandhiji had listed 'science without humanity' as one of seven deadly sins. Scientists, therefore, have an onerous responsibility towards society and their fellow beings. They must distinguish between socially beneficial and socially harmful applications of their research and innovation," he said.

Ansari suggested increased communication between the scientists and the public, civil society and policy-makers to find and implement solutions to issues of public need and interest.

"They could also take into account important questions such as reconciling the profit motive with the common good; providing for contributions from and benefits to deprived and marginalized segments of society; justifying current costs to prevent costs or damages to future generations...," he added.

Adding that science needs to be fully integrated with the broader needs of the society, Ansari said: "Science also has to be cognizant of the social and ethical imperatives, which are integral to our being human and the basis of our civilization."

1. Field of the Invention
Embodiments of the invention relate to a method and apparatus for contacting a substrate, and more particularly, to a method and apparatus used to contact a substrate during an electrochemical plating process.
2. Background of the Related Art
Metallization of sub-quarter micron sized features is a foundational technology for present and future generations of integrated circuit manufacturing processes. More particularly, in devices such as ultra large scale integration-type devices, i.e., devices having integrated circuits with more than a million logic gates, the multilevel interconnects that lie at the heart of these devices are generally formed by filling high aspect ratio, i.e., greater than about 4:1, interconnect features with a conductive material, such as copper, aluminum, nickel, gold, or other conductive material. Conventionally, deposition techniques such as chemical vapor deposition (CVD) and physical vapor deposition (PVD) have been used to fill these interconnect features. However, as the interconnect sizes decrease and aspect ratios increase, void-free interconnect feature fill via conventional metallization techniques, i.e., PVD and CVD, for example, becomes increasingly difficult. Therefore, plating techniques, i.e., electrochemical plating (ECP) and electroless plating, have emerged as promising processes for void free filling of sub-quarter micron sized high aspect ratio interconnect features in integrated circuit manufacturing processes.
In an ECP process, for example, sub-quarter micron sized high aspect ratio features formed into the surface of a substrate (or a dielectric layer deposited thereon) may be efficiently filled with a conductive material, such as copper. ECP plating processes are generally two stage processes, wherein a seed layer is first formed over the surface features of the substrate or dielectric layer, and then the surface features are exposed to an electrolyte solution, while an electrical bias is applied between the seed layer and a copper anode positioned within the electrolyte solution. The electrolyte solution generally contains ions to be plated onto the surface of the substrate, and therefore, the application of the electrical bias causes these ions to be urged out of the electrolyte solution and to be plated onto the electrically biased seed layer.
Conventional electrochemical plating cells utilize a contact element or contact ring that is configured to electrically engage a perimeter of the substrate surface in order to supply the electrical plating bias required to initiate and sustain plating operations. However, one drawback to this configuration is that when the substrate surface is immersed in the plating solution, the electrical contacts also generally contact the plating solution, and as a result thereof, metal ions in the solution are generally plated on the electrical contacts themselves and not on the substrate surface. In order to overcome this challenge the plating industry has attempted to provide contact elements that have a dry contact-type configuration. i.e., the electrical contact or contacts are generally surrounded by a seal that prevents the plating solution from touching the contact pins. Dry contact configurations show promise in that they are designed to isolate the electrical contact elements from the plating solution, which prevents metal ions in the solution from plating on the electrical contact elements. However, one challenge associated with dry contact configurations is that the pressure differential between the region where the plating solution is contained and the sealed region surrounding the electrical contacts has been shown to be prone to solution leakage, which eliminates the advantages provided by the dry contact configuration.
Therefore, there is a need for a dry electrical contact element for a substrate plating apparatus, wherein the dry electrical contact element overcomes the challenges associated with pressure differential driven fluid leakage across the dry contact seals.

This results in the deposition of a thin layer of metal on the surface being plated.

## IV. How Electrochemical Plating Works
Electrochemical plating works by immersing the conductive surface to be plated in a solution containing the metal ions to be deposited. An electric current is then passed through the solution, which causes the reduction of metal ions at the anode and the oxidation of metal ions at the cathode. This results in the deposition of a thin layer of metal on the surface being plated.

## V. Conclusion
In conclusion, electrochemical plating is a valuable process that has many applications in various industries. By understanding the principles behind this process, we can better appreciate its importance and potential for innovation.
