Artificial intelligence in healthcare

In this age of technology, AI (Artificial Intelligence) knows no bounds. Even though it is invoking fear in all of us, it is also benefiting most of us in various ways.

What is AI?

AI is the development of computer systems that can perform activities which require human intelligence like decision making, solving complex problems, etc.

AI in healthcare

Since the introduction of AI, it has impacted various domains such as marketing, finance, gaming industry, music, and art. However, the major impact is on healthcare. AI in healthcare is revolutionising the medical industry by providing a helping hand. It is undeniable that AI is saving lives.

AI in data management

AI helps in implementing cognitive technology to store medical records and perform power diagnosis. For example, it automates the tedious tasks of the user by implementing an automated system that would send SMS, email, etc. The use of AI based chatbot makes things easier.

AI in medical diagnosis

AI along with neural networks and deep learning is revolutionising the image diagnosis field in medicine. For example, it has taken over the complex analysis of the MRI scan and made it a simpler process.

AI in early detection

AI helps in the early prediction of medical conditions such as heart attack. AI based wearables such as Fitbit, Apple smart watch, etc. act as health trackers. They have been developed to monitor the health of a person and display warnings when devices collect unusual or unlikely data.

These smart watches collect data like heart rate, sleep cycle, breathing rate, blood pressure, etc. which are processed and analysed using machine learning and deep learning to create a model which helps in prediction of risk.

AI in medical assistance

AI based virtual nurses are developed to provide self-care and clinical advices, schedule an appointment, etc.

AI in decision making

The AI plays a major role in decision making by studying user needs and evaluating any potential risk.

The use of surgical robots can minimise errors, variations, and eventually help in increasing the efficiency of surgeons. One such surgical robot is da Vinci which allows professional surgeons to implement complex surgeries with better flexibility and control than conventional approaches.

Risk of AI in healthcare

Along with its various benefits, AI also adds potential risks in the field of healthcare. Such threats include false positives/negatives, system errors, unexplainable results, etc. In order to avoid this risk, physicians must seek training in proper usage of AI. Such training must also be incorporated as a standard component of medical education. Hospitals are also encouraged to use AI to ensure proper development, implementation, and monitoring of protocols.

With fast developing technology in this age, the human kind is to largely benefit from AI. We can reap this to the maximum extent if we are cautious about the dangers of it. visit our Akshara blog to read more such articles.

What is magnetism?

Magnets. Cool playthings. They attract other magnetic substances. Two magnets repel when their like poles face each other, attract when their unlike poles are brought together. We all know the basics. We also know that they are used in innumerable ways in our daily lives. In televisions, phones, microphones, refrigerators, giant cranes that lift junk cars at a scrap yard are just a few examples to begin with. But, what are these magnets and how do they get such a cool property?

Let’s just dive right into it. Magnetism is a physical phenomenon produced by the motion of electric charges, which results in attractive and repulsive forces between objects. Yes, that’s right. It is caused by a moving electric charge. Now, we know that matter is made up of atoms and atoms have subatomic particles such as protons, electrons, etc. These charged particles create a field around them when they are in motion.

Let’s just dive right into it. Magnetism is a physical phenomenon produced by the motion of electric charges, which results in attractive and repulsive forces between objects. Yes, that’s right. It is caused by a moving electric charge. Now, we know that matter is made up of atoms and atoms have subatomic particles such as protons, electrons, etc. These charged particles create a field around them when they are in motion.

Since all objects are made up of subatomic particles that are in motion, shouldn’t they all exhibit magnetism? To understand this, we must take into consideration a couple of things. Firstly, the magnetic field of every object/atom is not the same. For example, the magnetic field of a proton is much weaker than that of an electron. Some materials could exhibit magnetism, but due to their weak magnetic field, we may not see them moving other magnetic objects towards or away from them.

Secondly, the net magnetic field of an object/atom could be zero. Try and imagine this – every electron in motion produces a magnetic field around it. Therefore, they act as tiny magnets themselves. Now, each of these electrons has a spin, i.e. an intrinsic angular momentum.

The electrons with opposite spins (spin up and spin down) pair together while filling the electron orbitals of an atom.  In an atom with a completely filled outer electron orbital, the net magnetic field is zero as the electrons with opposite spins produce magnetic fields in the opposite direction which tend to cancel out each other. But, if an atom has a half-filled outer electron orbital, then the electrons have the same spin (either spin up or spin down) and they all produce a magnetic field in the same direction. Hence, the net magnetic field of the atom is not zero. This can be seen in atoms with one or more unpaired electrons too.

The more popular magnetic substances are iron, nickel, and cobalt as magnets apply an attractive force on these metals. These metals exhibit a property called “ferromagnetism”. There is a history behind the name that we will explore some other time. What we need to know is that if a large number of unpaired electrons with the same spin align, they produce magnetic fields in the same direction, strong enough to be experienced at a macroscopic level. But, it is not enough that an atom or all atoms of a substance produce net magnetic fields. It is necessary that these net magnetic fields of each atom in that said substance are in the same direction for them to not cancel out each other. Chromium is an example of a metal that has a magnetic field at the atomic level, but not at a macroscopic level. What this means is, the atoms of chromium have net magnetic fields, but when a piece of chromium metal is taken, a net magnetic field is not observed. How is that even possible, right? Well, it exhibits something called “antiferromagnetism”. What is antiferromagnetism? Are there other types of magnetism than these two? There are. But, that is a topic for another day.

Its high time to switch to alternative sources of energy

Fossil fuels are traditionally used by humans as a source of energy. These energy sources are non-renewable and are consumed at a higher rate. All this natural resources are on the verge of depletion and moreover they also cause pollution. Therefore it is essential for every body to conserve these resources. This is possible only if we switch to alternative sources of energy.

Photosynthesis

Plants prepare their own food, consume, and store the extra food being prepared and use them later. Preparation of food in plants is called photosynthesis. It requires an essential pigment, chlorophyll, which traps solar energy and converts the raw materials; carbon dioxide and water into carbohydrates. The excess carbohydrates are converted as soon as they are prepared to starch and stored in storage organs. At night, photosynthesis does not occur as there is no sunlight. In such situations, the stored food is used by the plants to carry on their life activities. So plants also eat!

Trick to verify the answers obtained using Factorization Method

A Quadratic polynomial is of the form ax^2+bx+c. When the standard quadratic polynomial is equated to zero, it becomes a quadratic equation. Usually, factorization method is used to find the roots of the quadratic equation, i.e. splitting the middle term. Here, two tricks are proposed to verify the roots of the quadratic equation in a very less time.

Verification of the problem is very important because sometimes the whole problem may go wrong just because the roots obtained are wrong. So, checking the answers before proceeding to the next step is important.

How to cover entire syllabi in less time?

Students studying the night before the exam may or may not perform good. What to do in such situations? How to cover entire syllabi in less time? First, try to break down the chapters into smaller chunks; topics. Select the easiest topics and complete it. Try to read the summaries or extracts you prepared while attending the class at school. Try to go through previous year exam papers and chapter-end exercise in the textbooks. Try to make tricks/mnemonics to recall the same. Summarise or teach your friends what you learned at regular intervals. Take breaks in between study time. A tired brain cannot focus and learn fast.

Is sleep really essential?

A few days back, I got a scolding from mother for not going to bed on time. I was very angry and cried because I wanted to play for some more time. Finally, I had to obey my mom’s orders and go to bed. I had decided to stay awake till late at night in the bed and wake her up to prove her wrong. But when I opened my eyes, it was already morning!! I had fallen asleep within a few minutes.

I ran to the hall and asked mom “Why do we have to sleep?” She said, “Everybody, including all animals need sleep to survive and function. Sometimes we don’t realise it and then get angry for small reasons.”  “Ok. But why is it so important?” I asked. “Sleep allows our body to rest. It is very essential for learning and performing well in your work,” said mom. “Do you remember the day we came back late at night from granny’s house?” asked mom “how drowsy were you in the class? Your teacher sent a note to complain about you. Why do you think that happened?” “I was very sleepy,” I replied defensively. “Yes. Sleep is essential for alertness, maintaining all body-function rhythms, and also for your mental health,” added mom. “Was this the reason I was cranky and cried last night?” I asked. “Yes,” said mom laughingly. I found it very interesting and decided to get some more information on sleep. In the library, I found many books on sleep. Reading one of the books, I learnt that sleep is of two types, REM and Non-REM.

I found it very interesting and decided to get some more information on sleep. In the library, I found many books on sleep. Reading one of the books, I learnt that sleep is of two types, REM and Non-REM.

Non-Rapid Eye Movement (Non-REM) sleep

It is also known as “quiet” sleep. During this, important hormones are released for growth & development. It also helps in tissue growth and restoring energy. Maybe this is why young children sleep more than old people?

REM (rapid eye movement) sleep

During this, our eyes move back and forth very quickly beneath our eyelids, whereas the rest of our body is totally relaxed.

Do you know what I found very interesting? REM sleep is when we dream! Some scientists think that dreams help us to organise our memories and emotions. It’s like every night when we go to sleep, we transfer information from temporary cupboard to permanent cupboard (scientists call it short term memory to long term memory).

Do you know there are five stages of sleep? They are:

Light Non-REM sleep

Slightly Non-REM deeper sleep

Deeper Non-REM sleep

Deepest Non-REM sleep

REM sleep

Repetition of alternate REM and Non-REM sleep occurs. This forms a sleep cycle. During our night’s sleep, we go through many such cycles. I read about sleep disorders such as insomnia, where people are unable to sleep due to stress. I also read about sleepwalking,  where people walk while sleeping! Isn’t that scary? What if someone goes out of the house while asleep?

When I came home and told Mom about everything that I read, she was very happy. “This is precisely why your teachers and I tell you to rest well, especially before and during exams. If your brain doesn’t get enough rest, you might not be able to do your best,” said mom.

Since that day, I sleep on time without any arguments. I also follow some practices which help me get good sleep. They are:

Avoiding watching scary movies before going to bed

Not drinking tea or coffee before sleeping

Not exercising before sleeping

Following a schedule for sleeping

Basically, I learnt that sleep is necessary for the perfect functioning of our body.

Ok, now it’s almost my bedtime. See you later. Good night. Sweet dreams.

How to overcome the fear of maths

Maths is the base for many scientific and technological discoveries. It is one of the oldest subjects and is constantly being rejuvenated. Many of the other subjects are dependent on maths. Maths is all around us, and has an important role in our life. Right from a farmer, cook, doctor or a mechanic-everyone needs maths in their day-to-day life.

But thinking of maths gives most people jitters, they get sweaty and their heart beats faster. It’s fair to say maths is not everyone’s favorite subject. In fact, for many people, the feelings of tension and anxiety that arise when trying to solve a mathematical problem can be like hell. This is known as maths anxiety and this feeling of being a failure at maths can affect people’s mind badly.

For those who suffer with maths anxiety, it can be difficult to shift from a mindset of a failure to a more positive outlook when it comes to dealing with numbers. That is how, for many people, maths anxiety can become a lifelong issue.

Students usually tend to inculcate fear of maths because of lack of confidence, lack of knowledge in basics, not understanding the concept properly, not studying the formulae, etc.

Here are some tips to overcome the fear of maths

Don’t be scared to learn formulae Learning formulae is very important. So, make a note of all the formulas and go through them anytime and anywhere.

Identify and accept the fear If we are afraid of anything we have to admit it, because just accepting the fear does not make you a failure. But not taking care of that fear may affect your life. Find the cause of the failure and work on it. Continuous hard work leads to success.

Do not try to mug up the things Maths should never be confused with other subjects where mugging is required. Do not byheart the formulae or solutions, try to understand the procedure and then solve the problem.

Do not read maths Do not sit and read maths like any other theory subjects. Sit and solve all the problems from the textbook.

Ask questions when you do not understand If you do not understand the concept or any problem, get your doubts cleared by a teacher or your peers.

Do not jump directly to the solution Always solve the problems step by step by understanding the logic of the problem. So that you avoid making mistakes. When one step is wrong, the whole problem will be wrong.

Practice the problems based on the concept If one thinks they know a problem very well they should practice more on that concept and should make it a rule to do each and every problem present in the textbook.

Make a test plan After practising all the problems, write a test. The test is only to measure how well you have understood the problems, and the time taken to solve the problem.

Debunking Public Myths on COVID-19 – A Pandemic

Since late 2019 and the beginning of the year 2020, the world has been suffering from an ongoing pandemic; COVID-19 caused by SARS-CoV-2. People of India and other parts of the world are experiencing worldwide shutdowns and region-wise lockdowns.

What is more interesting amid COVID-19 is the reconstruction of nature.

Endangered species being spotted at various places

Reduction in air pollution

Reduced vibrations on the earth

“Corona, quarantine, masks, 6 ft distance from each other”, these are currently the trending words. In the midst of all these, we also experience traffic in google search, as people all around the world are curious to know about the serious effects of the ongoing pandemic and work from home.

Despite the experiences shared by the people who have recovered from this pandemic, people are constantly in search of news regarding the spread and preventive measures of COVID-19.

It is advised that one believes in the facts and takes appropriate measures rather on MYTHS.

COVID-19 is the name of the disease and not of the virus.

COVID–19, previously known as “2019 Novel coronavirus” is a disease caused by the virus SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2). Like for any other viral disease, the virus and the disease are named by different names. COVID-19 is the acronym of “Coronavirus disease 2019”. The virus is termed ‘Novel’ as it’s a new virus. It began with an animal population, got transmitted to humans and presently can be transmitted from human to human. Our immune system has not encountered this strain of virus before, therefore we have not developed immunity.

COVID-19 cannot be prevented by exposing oneself to high temperatures (more than 25 °C) or living in hot climate regions.

Countries with hot weather have reported COVID-19 cases. Therefore, you can still catch COVID-19 no matter how sunny or hot the weather is.

If the virus can sustain in the normal average body temperature of 37 °C inside humans, then it is evident that it survives in higher temperatures. Again, hot baths are not going to work.

“Adopt protective measures by washing your hands frequently and thoroughly and avoid touching your eyes, mouth, and pricking your nose.”

Staying in cold and snow regions cannot protect you from contacting the SARS-CoV-2.

There is no evidence to prove that cold weather can destroy the coronavirus. The normal human body temperature remains within the range of 36.5 °C to 37 °C, regardless of the external temperature or weather.

“WHO advises people of all ages to take steps to protect themselves from the virus, for example by following good hand hygiene and good respiratory hygiene.”

People of all age groups can be infected by the coronavirus. COVID-19 infection is not specific to an age. Older people and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus.

People infected with COVID-19 need not live with it forever. Individuals can recover from COVID-19. If you contact the disease, make sure you treat your symptoms. If you have a cough, fever, and difficulty breathing, seek medical care early – but call your health facility by telephone first. Most patients recover thanks to supportive care.

The ability to hold your breath for 10 seconds or more without coughing or feeling of discomfort does not mean you are free from COVID-19.

Signs and symptoms may appear 2 – 14 days after exposure to the coronavirus. The most common symptoms of COVID-19 are dry cough, tiredness, and fever. Some people may develop more severe forms of the disease, such as pneumonia. The best way to confirm if you have the virus-producing COVID-19 disease is with a laboratory test. You cannot confirm it with such breathing exercise. Holding your breath for 10 seconds can even be dangerous.

Consumption of alcohol does not protect you from contacting COVID-19. Consuming alcohol can increase your risk of health problems and overdose is fatal.

Agents like mosquitoes and other insects cannot transmit the COVID-19.

COVID-19  mostly spreads through droplets produced when infected people sneeze or cough and by touching contaminated surfaces. It’s easy to think of mosquitoes as tiny flying dirty syringes transferring droplets of infected blood from person to person. The reality is far more complex. When a mosquito bites and sucks up some blood that contains a virus, the virus quickly ends up in the gut of the insect. From here the virus may start utilising the nutrients and multiply or it may perish in the gut depending upon its genetic makeup.

“There is no evidence for COVID-19 infection being transmitted through agents like mosquitoes.”

Placing your hands under dryers will not prevent you from contacting the COVID-19 infection.

To protect yourself against the coronavirus, you should frequently clean your hands with an alcohol-based hand sanitizer or wash them with soap and water, at least for 20 seconds. Once your hands are cleaned, you should dry them thoroughly by using tissues or a warm air dryer.

Spraying alcohol or chlorine all over the body may not destroy the coronavirus present inside your body. Inhalation of chlorine gas/aerosols causes eye, nose and throat irritation, burning sensations, and sneezing. They also cause skin irritation. High exposure to chlorine may lead to nausea and vomiting.

Alcohol breaks down the immune system in the lungs, making them more susceptible for infections. It can also cause life threatening acute respiratory distress syndrome (ARDS).

Eating garlic and drinking jeera water is not an alternative for Corona vaccines or treatment of the same. Garlic is a healthy food that may have some antimicrobial properties. However, there is no evidence from the current outbreak that eating garlic has protected people from the new coronavirus. Jeera water is only an immunity-boosting drink. Vaccines for COVID-19 are under development.

antibiotics to prevent and treat COVID-19 patients.

Antibiotics work only against bacterial diseases. And we know COVID-19 is a viral disease. However, antibiotics are used to treat infected patients because bacterial co-infection is possible.

“There are no vaccines produced against corona virus. The virus is so new and different that it needs its own vaccine. Researchers are trying to develop a vaccine against 2019-nCoV, and WHO is supporting their efforts.”

Although there are no effective vaccines against 2019-nCoV as of now, general vaccinations against respiratory illnesses is advised to protect your health.
