Covid falls and worrying cases

18 Oct

Covid 19 already shows signs of decline worldwide, but there are still worrying cases such as Russia, the first country to launch a vaccine and had on Saturday (16/09) more than a thousand deaths from Covid 19, the reasons are several, the main thing is the low rate of vaccination, Russia reached 218,362 thousand deaths for a population of 145 million inhabitants.

The whole world has almost 48% at least one dose and just over 36% fully immunized, it is possible to consider that we are not out of danger, something around 60% would be desirable, at least until the end of the year for the Christmas parties , in Brazil the number of vaccinees is 73.4% at least one dose and close to 50% fully vaccinated, but the infection curve still drops very slowly.

The consequences of Variant delta are not yet known, in a balance made of the pandemic by neuroscientist Miguel Nicolelis, he stated that in Brazil we have not yet seen the face of this variant.

Winter is approaching in the Northern Hemisphere and the WHO intends to consider the possibility of a new pandemic, so that we are not surprised as this one has not ended, in November it will hold a World Health Assembly where it will study the possibility of a “treaty for pandemic”, it is necessary to consider greater solidarity and more effective combat.

The deputy director of WHO Mariângela Simão was emphatic: “there will be a next pandemic”, and added: “This is something we already know and which is inevitable, it’s a question of when it will happen” said according to the Instituto Paulista of Medicine.

Simão alerts that there is no approved vaccine yet for children, so there cannot be a national policy using vaccines that have not been approved for children under 12 years of age, and he points out that we only have one vaccine approved for use by adolescents from 12 years of age, which is the Pfizer.

He highlighted the importance of the Covax consortium that helped vaccination in poor countries, stressing the importance of donating 500 million doses from Pfizer, which will allow the entry of 200 million doses from Pfizer this year, France also made available the make donations and more countries are expected to help because, for now, it is the only vaccine for teenagers.

 

 

The danger of the delta variant and vaccination

02 Aug

Concerns are growing about the delta variant of the coranavirus,  the indication is that some vaccines may not be fighting this variant, the growing number of infections, even in countries with advanced vaccination, is worrying.

WHO Director Tedros Ghebreyesus said two days ago to various media outlets at a press conference: “New cases of contamination and deaths continue to rise. There were 4 million new cases in one week. At this rate, we will surpass the mark of 200 million of infected in two weeks, although we know that this is an underestimated number”, he pointed out.

Since the third week of July, Europe and the United States have again registered an increase in infections due to the delta variant.

Even in China, which had controlled the pandemic, this number grew again, still small (200 cases), but it is already spread over several regions. peoples in dangerous cities will be tested.

In Brazil the moving average is below a thousand daily deaths, it slowly drops as vaccination progresses, but cases of the delta variant already appear in the country, and the real effectiveness of the vaccine in relation to this variant is concerned, there is poor monitoring in some states, testing should begin immediately and en masse, there is no evidence.

The idea of making the measures more flexible continues and will probably not go back until another outbreak, only one state (Rio de Janeiro) registers an increase, 8 states in stability and 15 in decline (São Paulo is one of these).

The WHO and the World Bank call for the urgent application of vaccines in poor countries, the average in high-income countries is the application of 98.2 doses per 100 inhabitants; while in low-income groups, the number is 1.6 doses per 100 people.

Regardless of the effectiveness of vaccines, vaccination must continue and so must restriction.

 

The unpredictable future of the pandemic

15 Mar

It is becoming increasingly clear that the future of the pandemic may be far from what everyone imagines, the number of variants of the virus, scientists are beginning to identify the small variations it makes in its genetic code, and for years epidemiologists have said that we should be prepare for a next pandemic, if we haven’t done it before, now more than ever should be done.

Meanwhile, the epidemic shows no signs of cooling, despite the number dropping, in Europe for example, there was a considerable increase this week, of every 100 infections registered in the world, 41 are from Europe, the Brazilian case we have already revealed is tragic due to the records infections and deaths higher than last year’s data.

The studies on the variants also find a change in its genetic code that is frightening because with each transmission, changes in the genetic code can influence the efficiency of the vaccine (we have already explained the efficacy rates that depend on the “type” of the vaccine), that is it may happen that the next epidemic is the coronavirus itself in one of its mutations.

What to do for now, increase the vaccine and combine it with lockdown, is a cultural fact that will be difficult in Brazil and the restrictions are highly unpopular, but there is nothing else to do, and it needs to be combined with increased rates. vaccination.

Another problem is the humanitarian crisis that can occur, limiting the movement of people means limiting trade, consumption of goods, etc., which in 2020 had a positive fact, since the little circulation of vehicles and the use of non-renewable energies, it caused CO2 emissions to drop by an average of 6% across the planet, and some signs of nature rehabilitation appeared, the presence of dolphins close to the coast, which means an abundance of fish, improved levels of pollution in large cities.

However, it is important to say that the number of deaths grows that had started to decrease, returns to very worrying levels, and new bouts happen again due to the virus variants.

The economy must also be a worrying factor because there are already signs in many countries of social problems, unemployment, poverty levels and related issues: income distribution and impoverishment.

We can learn from this cruel lesson, but still most people care little about what hasn’t directly affected them yet, but it will gradually affect everyone.

 

 

Vaccination and options

07 Dec

The UK starts its mass vaccination on Tuesday, which will be 40 million vaccines for 20 million people, due to the need for two doses of the Pfizer vaccine.

The effectiveness is around 95% and the side effects in about 2% of the volunteers are headaches and fatigue, similar to a strong hangover, however there will be other vaccine options.

Differently in Brazil, the options are small and the effectiveness of the vaccine, despite all the political propaganda surrounding the federal government’s AstraZeneca / Oxford vaccine and the São Paulo government’s Coronavac, both are much less efficient and have popular distrust.

State and municipal health secretaries published on Saturday (5/12) on the website of the Brazilian National Council of Health Secretaries (Conass) a request that the federal government acquire all vaccines against Covid-19 with proven efficacy and safety, economic interests / politicians must unfortunately prevail and we will be left with few options.

What leads us to distrust political and economic interests is the disregard for efficiency.

Two reasons are important in terms of efficiency (it is different from effectiveness), the first is that which mobilizes the natural system we have (the majority representatives are macrophages) and that develops a defense independent of the infectious agent, the second and second if the system is not enough (see su-efficient root) it mobilizes the adaptive or acquired immune system, which is more sophisticated and dependent on the type of bacteria or virus, this system must “generate” defenses (the most representative are the lymphocytes).

What proves that this is true is that all the agencies say that there is no guarantee of the end of the pandemic, and we must remain taking care of protection, time will tell and it will not cost more lives.

 

 

Lockdown and frivolity

11 May

As the virus expands and begins to arrive more in the interior of Brazil and in many places life remains “normal”, while Europe is gradually trying to return to a new normality, that is, to return to trade and consumerism and the previous hectic life , which Sloterdijk calls frivolity (see in daily El país).

There are two scenarios, the Brazilian case while some bet that the curve reached the plateau, the new data point to an even greater expansion of the virus, betting that we can contain the serious pandemic situation with little radical measures is proving inefficient.

The reason for the pressure to open trade, more than economic, it is clear that it affects the economy of the whole planet, the real reason in the minds of many people is to return to the day to day of high stress, rush and consumerism to those who have the resources for this.

In Brazil, we have reached the level of 10,000 deaths, both in personal and social life, if we reach a seriousness of a disease or take radical measures or witness the total aggravation of the disease, in the social case, the viral expansion and the worsening of the pandemic.

In the reflection of Sloterdijk, who wrote, in my view, two emblematic books Spheres and Criticism of Cynical Reason, he presents two key concepts that are co-immunity and anthropotechnics.

The first concept of co-community means that we can establish an individual commitment towards mutual protection, which would mark a new worldwide way of facing problems and the concept of anthropotechnics means understanding that the techniques, in this case and is the main concept used by Sloterdijk, the biotechnology, this is genetic manipulation.

When launched, it generated a lot of controversy in Europe, due to the manipulation of genes for example, but now that the main researches in defense of the coronavirus show the importance of the use of antibodies for the production of the vaccine, and the first thing was the genetic sequencing.

The worsening of the Brazilian crisis will require a more serious confinement, or we will see the figures extrapolate and the Health System already practically exhausted.

Confinement is necessary and the return to frivolity must be rethought as a way not only to avoid a major economic crisis, but mainly fairer. 

 

#NoWar

06 Jan

General Qassem Soleimani killed in Baghdad, Iraq, was Iran’s second most powerful person and could break the fragile balance between international forces, and the danger of a war of world proportions becomes a fearful possibility.

Iran has countries like China and Russia as allies, in addition to the Arab and Muslim world, which today is a world-class religion, and this may have a global outline of terrorism another possibility.

The security agencies set off their alarms, social media was the most talked about subject of the week, and anyone who imagines this is not serious, does not know the horrors of war: death of innocent people, food shortages, energy breaks, travels and interchance breaks and mainly increased a climate of hatred and intolerance across the plane.

Peace must be desired, and the UN, OAS and international dialogue bodies need to act.

 

Web Summit in Lisbon

08 Nov

One of the biggest events of the Web was this week, it was a side event, I could only follow videos and news, undoubtedly the biggest star was the founder of the Web Tim-Berners Lee who already has a great new project, although he has spoken between the lines.

He started an interview, which in fact he spoke at will without many questions saying the beginning of the Web and how his growth was also surprising for him, he told technical details like “I wrote the code of the first server and the code of the first browser, it was called WorldWideWeb.app “and was on info.cern.ch.

He then said that his concern is the same as everyone, after 25 years we should deal with: cyberbullying, misinformation, hate speech, privacy issues and said what many are talking about, “What the hell could go wrong?” to the public: “in the first 15 years … great things have happened. We had Wikipedia, the Khan Academy, blogs, we had cats, “he said jokingly, adding:” Connected Humanity should be more constructive, more peaceful, than Humanity disconnected”, but jnt (just not).

“Because we are almost at the point where half of the world will be online”, explained the British engineer was referring to the ’50 / 50′ moment, that is half the connected humanity expected in 50 years, but it should reach this point in May 2019.

After trying to argue the responsibilities of governments and companies, I believe they can happen but they will be slow, he spoke indirectly of his SOLID (Social Linked Data) project, stating that “as individuals we have to hold corporations and governments accountable for what is happening on the internet ” and “the idea is, from now on, everyone is responsible for making the Web a better place, “said encouraging start-ups too to get into this process.

Thinking about the development of interfaces where users know people from different cultures, but above all ensure the universality of the Web, according to Berners-Lee the main aspect should be (speaking indirectly again of SOLID) that the popular intervention at global level and that made the Web “just a platform, without attitude, that should be independent, can be used for any kind of information, any culture, any language, any hardware, software”, linked data may help this.

 Tim Berners-Lee presented the #ForTheWeb movement on the same day that his World Wide Web Foundation released the report “The Case for the Web”, the event had a superaudience, more than 30 thousand people, there are several videos, but the Opening Ceremony is one of the most outstanding and has Tim-Berners Lee as well, see on vídeo: https://www.youtube.com/watch?v=lkzNZKCxM

 

Are machines becoming humanized?

02 Nov

Summary of Lecture by prof. Dr. Teixeira Coelho from IEA – USP at the EBICCJoseTeixeiraCoelho event.

Are machines becoming humanized, or are they the human beings that are losing humanity and transforming into immediate, as valuable, as excessive and totally subdutable products of which the world is full?
The lecture presented as results of the study group Computational Humanities of the Institute of Studies
Advanced of USP a list of concepts, most with a critical view of technology, terms such as: digitization, mobility, automation, augmented reality, proxy effect, duplication, anonymity, perfectibility, rationality, coordination, unification and completeness, among others, like the result of an e-culture.
He discussed the contemporary reality of computational and digital cultures and their relation to cultural production, mediated or self-produced, in a context where the work of robots replaces the manual work of humans and goes to replace, through artificial intelligence, intellectual work .
Gregory Chaitin then gave his talk, already discussed in the previous post.

 

The world hacker attack

15 May

It is already the biggest worldwide attack, the numbers counted until WindowsUpdateSunday (14/05) already surpassed 200,000 infected computers in 150 countries, but like any digital virus there is no deadline for it to end unless the systems are permanently protected, because of this the update is so necessary.
The virus type ransonware, a malware that installs itself on your computer, encrypts all data and blocks them by requiring payment (in this case in bitcoins, digital currency) and does not allow you to access your own programs and data.
It was called by the Wanna Cry hackers themselves, considered a high-level malware distributed as Deep Web, and the information says that it was an adaptation of a US NCSA portlet (intelligence department) and this would be precisely to encrypt and capture data of citizens and businesses.
For those who have ease in using the Windows environment, going in settings you will find the Update and Security screen (Windows update) and must wait for the update that may take a while, but will also update Windows Defender, which in the current version already has the vaccine against this virus.
If the program does not fully upgrade, it is because your Windows is not original, so it means you will still not be safe.
However, researchers are not going to disclose the strategies, but they can basically be three: trace the historical origin of the attack, track where the current attacks are coming from, and unconventional mechanisms.

To verify the use of bitcoins, since they are pseudonyms (pseudo-currencies) that must be transformed into existing products or currencies to be rescued the values ​​of the hijacking of data made by the hackers.
It is increasingly important to keep data backups on cloud backups or an external hard drive.

 

The Next Step to Cognitive Intelligence

23 Feb

We are approaching a century of computing, if we think that Kurt Gödel’sSegurançaIBM paradox about a thinking “system” began what Alan Turing and Claude Shannon would talk about in secret Bell Laboratory projects during World War II, read The Information: a History, a theory and a flood of James Gleick, to understand what was done, until the first computer was created in valves.
Then we develop increasingly complex programs, and we can simulate genome sequencing, weather forecasting, sharing data around the world, but the most interesting pieces for us humans, such as creating a poem, recognizing an image of painting or even reading a Book, explaining it so that systems still fall short.
Now concerned with security systems, machines advance our desires and individualities, they finally seem to challenge the developers: to create a cognitive security capable of going beyond the machines, and to continue to give us security to work with them.
For decades, computers have been trained to recognize viruses, malware and exploits, and we have tried to make these services more accurate, but it is not enough, machines seem to discover our desires and offer things to make us offers and throw us on even stronger consumption Than at the beginning of the cinema and radio era.
Now your attacks and find creative ways to break the defenses, so what systems need is the ability to detect the most subtle change of activity and analyze it with as much context as possible to distinguish and eliminate new threats?
IBM promises to move forward on these smarter, now called cognitive, segregations, Samsung also promises advanced programs in this area, with two key points:
– traditional security is unable to analyze and apply this view in the way that an analyst can. That’s why the most challenging security issues still require people to make good decisions about how to act and how to know if it’s not a false alarm.
– the second is to build a kind of “security instincts” and expertise in new defenses that analyze search reports, Web text, threat data, and other structured and unstructured security-relevant data – just as security professionals do on a daily basis – but on a scale never seen before.
This is the essence of cognitive security, be it the IBM video above.
