Large smart Have little relationship to intelligence and brain size

　　Having a larger brain equated higher intelligence? the problem has baffled scientists for centuries. And now, researchers explain why some people smarter than others found brain size in here only plays a small role.

　　Researchers believe that brain structure is the key to interpret intelligence. And as early as 1836, Germany anatomist Friedrich Tiedemann said in an article published in his brain the size of its features, functions, there is definitely a connection between.

　　Since then, experts divided agree with faction and the opposition. To this day, an MRI scan of brain imaging methods, such as allowing them to more accurately assess the brain capacity, and more reliable than ever. Victorias Secret iPad Mini Case

　　In order to study the relationship between brain size and intelligence, an international research team led by the University of Vienna to 148 contains 8,000 participants data samples are analyzed. They found that brain size IQ between a very stable but weak associations, nothing to do with gender and age of the participants. The study, published in the neuroscience and biological behavior of commentary magazine.

　　"Currently observed correlation means that brain size in human intelligence played only a small role in the process. "Jakob Pietschnig said from the Vienna Institute of applied psychology. In his view, although there is a correlation between the two, but the structure and integrity of the brain seems to be more important. Victorias Secret iPad Mini Case

　　However, at the time of comparison of different species and importance of brain size becomes very obvious. For example, sperm whales have the largest of the central nervous system, and hamsters are tops in weight control, humans have been dumped a few blocks away. Researchers say this suggests that differences in the structure of the brain causing the intellectual differences between different species.

　　Brain size and intelligence, and there is no direct relationship. As we all know, men's brains are larger than some women, but in the global IQ test, men and women show no significant difference. And people with big brain malformation syndrome in an IQ test score to be lower than the general population. Jakob Pietschnig, said: "from a human cognitive performance, the structure of the brain seems to be more important than brain size. "

　　It is interesting, in a recent experiment, researchers made a preliminary study of 226 patients with Alzheimer's, they found that brain size, especially the size of the hippocampus, can predict the chances of a person suffering from the disease. Previous studies have shown that the size of the hippocampus, can be used as criteria for evaluating the risk of Alzheimer's disease.

　　Aaron Bonner-Jackson from the Cleveland Clinic Research Center, says: "our hopes hippocampus size to detect early signs of Alzheimer's, making it another sign of the disease. "

Even the old vehicle traveling data recorder based on the week is a kind of

Not interesting events on the network last month sparked an interesting phenomenon, "Chengdu driver the street and beaten women drivers" after a few days, vehicle traveling data recorder in the whole network (Taobao, CAT) jump the number of search hits. Insiders told the reporter of Lei feng, within a week after the incident, vehicle traveling data recorder came a spike in sales, sales are usually 3 to 4 times.

Driving recorder rise started in the country in recent years, particularly after the 2012 and 2013, its sales began to spurt. But compared with huge car ownership (about 150 million or so), the absolute market share of vehicle traveling data recorder is not large, annual shipments of about 10 million units or so.

The reason was mainly because people buy the purpose of vehicle traveling data recorder single: just to prevent pence, frequency of use was not high, make the vehicle traveling data recorder has become a device. While in Korea, and Japan, and Russia or Taiwan region, driving recorder penetration is much higher than China's. Partly because the Government requires that every new car installation of vehicle traveling data recorder, on the other hand people realized the importance of traveling data recorder for traffic safety. Cath Kidston iPhone 6 Case

Traditional channels of vehicle traveling data recorder Cath Kidston iPhone 6 covers

Around the year 2010, initially in the East and there is no list of vehicle traveling data recorder, and later added to the automotive category directory. According to East of Beijing's own published data, sales of vehicle traveling data recorder the Jingdong last year ranked sixth of the consumer electronics.

One industry insider told familiar with driving recorder channel Lei Feng network, driving recorder now 60% to 70% sales are done online. But due to the through train, smoke, scalping and other cost increases, so its prices online sometimes are not lower than offline.

Below the line, vehicle traveling data recorder is generally issued through layers of, that is, in each province, to find a auto electronic products agents, before being sent to cities and counties all over, like car beauty shops, auto repair shops, etc.

Followed by Zhongguancun, Shenzhen huaqiang North, sanhao Street, Xujiahui electronic stores, but these places are now electric shocks.

Following is a May traffic recorder in Taobao and all brands of cat's sales ranking, for your reference.

The competitiveness of traditional vehicle traveling data recorder

Provide one vehicle traveling data recorder solutions the industry has told Lei feng's network, is currently in the Shenzhen team of vehicle traveling data recorder from early camera and camcorder solution team.

Kind of complicated products, most of the manufacturers do not have brand awareness, competition is usually best simply do flow, many rely on the scalp to increase sales.

Driving recorder's three main components including lens, DSP, and sensors. Lens testing, sensor debug and detail of the image determines the quality of a vehicle traveling data recorder. But these debugging is very subjective and no reference standards: for example, how to ensure sunny and cloudy but exposure can increase brightness, the transition from dark to light environment of the environment is smooth, and so on.

In addition, the current lens uneven standards of vehicle traveling data recorder market, camera manufacturers a lot, although there is a common standard, but no professional equipment to complete optical inspection.

Driving recorder brand first began to build technical barriers with the passage of time has ceased to exist, such as leaking seconds in the first two videos were conquered in succession by many manufacturers.

New vehicle traveling data recorder have a chance?

At at took founder Rayong told Lei Feng network, intelligent lane records instrument out zhihou, itself on has many imagine space, has many species play, do community, and security products,, while can hosted many function, like photo, and video share, and voice interactive or information synchronization,, more focused on experience and interactive, everyone can combined their of advantages to do such of things, let lane records instrument no longer is car within of a device.

Like stare at, Lu, Ding Dong or even flare, Car+ (the latter two are HUD, but also integrates the vehicle traveling data recorder features) such an up and comer, apart from the difference in product form, such products also can do a lot to improve: the integration of electronic dog, GPS navigation, and added new features such as video, collision warning algorithm.

Compared with the traditional driving recorder, change can be said to be functional and smart. But for them, the intelligent vehicle traveling data recorder has just started and not occupying a large share in the existing vehicle traveling data recorder. Just stare at a home, probably only 50,000 have been sold in the past year or so.

Summary

Currently there are two hundred or three hundred vehicle traveling data recorder makers "on their own", for they now divide or separate sites of the stage, and this situation will continue for a very long time. So the market needs a superstar of the vehicle traveling data recorder to promote the development of vehicle traveling data recorder market, so that more people notice vehicle traveling data recorder this product exists.

Traditional traffic recorder brands scattered, mostly OEM style complex features a single, ranging in price from 200 Yuan to 1000 Yuan, but still can not find a "benchmark" products.

But as the new vehicle traveling data recorder began to enter the market, it's not just recorded road condition cameras, it will also take pictures, share video, navigation, and micro-credit, QQ connection testing in-car air quality. If the function can meet the needs of owners, in the Red Sea which might even develop another piece of blue ocean.

Start first 360 heads of undertaking doing the safe application of mobile phone

Speaking of "UU security", I believe most of the Android mobile phone users say: what is this stuff? Mention 360 Mobile guardian, I believe that most users feel is like one of those years spent "Dumbo", every day! So what is the connection between them? Before the answer is 360 Mobile Guardian Technology Director, Chief Privacy Officer, Wang is the CEO of UU security now.

From 2007 to 2009, Mr Wang founded the Xin an easy, focusing on phone harassment prevention area, became the most famous cell phone harassment prevention products, accumulating tens of millions of users. 360 Mobile defender an easy users billions of predecessor.

In 2012, Wang Wei out of 360, after a period of rest, 14 he reinvent the business, best smartphone security APP--UU security. This APP claims to focus on Android platform under non-Root performance optimization and data security, layman's point is to give non Root Android users with a similar ability to Root management program you can disable boot, against the background does not exit, ban free to get the user's address book, SMS records, correspondence and other user information.

Wang Wei, 13 out of photo

How to achieve in management for mobile applications without Root? Jack Spade iPhone 5 Case

Wang told the reporter of Lei feng, Android is an open operating system, it gave permissions to each mobile phone applications is very large. Mobile applications can access a user's address book, contacts, you can automatically open, always in the background without leaving. This brings certain risks to mobile security and mobile phone brings a series of cards, slow and power consumption issues. But one thing is that Google gives a lot of freedom, nor have any bottom line. The bottom line is in the process of running and cannot interfere with other applications running, can't kill the other application processes, anti-virus software does not work, unless the phone is the highest Root permissions. Get highest Root permission to only way to Root the phone and Root itself pose a greater risk to the mobile device.

He has done this a UU mobile security application security is the solution to this problem.

                        General software into a green software, you can set up no boot and run in the background

UU concept of security has created a green software. Software to make a common green, coated with a layer of the original software, then reinstall on the mobile phone. Software is the same software that only runs in its own virtual machine, so that it can be applied to all things to manage. This is done under the Android operating system.

Greening process and there is no internal modifications to the application software, just pack a layer on the outside. Software binaries run as a whole is completely motionless, just after UU when system resources were mobilized in it security, and UU security filters will be added. So there is no infringement.

In fact, mobile phone manufacturers can be joined by phone the kernel module way UU functionality of core security technologies. Third-party development of software, what is different?

Wang said that Android application system to apply for permission when it calls a series of API to accomplish it. UU really is to intercept API calls, use system API to do things is not intercepted, is when access to resources in the API system, local control of resources, and it requires Root privileges. UU security API calls when the application is in a virtual machine, to control applications.

Mobile basic principles were the first to have an operating system that is running, such as Android, Android APP is running on top of the system. APP is not actually directly on top of the operating system is running, is running on a virtual machine. Android system is written in Java language, Java language cannot be run directly on the binary. Popular, is a virtual machine running on the operating system and APP running on a virtual machine. This virtual machine is responsible for all of the APP's operations and its instructions to the operating system to recognize things.

UU security is making a very thin virtual machine is a phone APP to put a green, this APP comes with a virtual machine, so that you can achieve the objective of comprehensive management APP without Root.

UU security is actually a security sandbox. Security sandbox is an independent environment, isolate user data, thereby protecting user data security. Security sandbox runs even unsafe, will not have an impact on user data, application can also control which permissions.

Industry insiders say other mobile application security sandbox are also doing this technique, but not spend too much energy on this, their product position is different. UU security focus to do this, in the field of security should be subdivided down more vertically, can also take a percentage of the target audience.

UU security by do of function no different, but Wang Wei said they of features is: "technology Shang, we green of of support rate far over other home, is has how many software can green of, we far Super they; performance Shang, we on space and memory of using efficiency Shang, also far Super they; function Shang, green of related of whole process, we also far than they perfect; they now of products, with we last year on new year's day Qian almost"

In fact, some mobile phone manufacturers are also to join their phone privacy rules and prohibition of technology start-up, but according to Mr Wang's judgment, is not suitable for the operation of mobile phone manufacturers, security software needs a lot of careful work, operating system vendors are doing bad, cell phone manufacturers to do more.

                    When converting a green software, tip needs to uninstall the software, the data needs to be backed up or they will be deleted

When in normal software into a green software, you need to uninstall the original version, if there is no backup, the existing data will be deleted. Wang Wei said, objectively speaking it is a barrier to user experience, but in the long run is not a fundamental obstacle to development. User didn't want to data lost of will is some micro-letter, and QQ, and paid treasure and so on such of application, UU security is wants to real solution user phone card, and slow, and power of problem, everyone of phone Shang are has dozens of a software, only several is trust of, other software is real caused card, and slow, and power of reasons, put these application turned into green soft, put they tube up on enough has.

Wang Wei's feelings

Wang said he left 360 for many reasons, one of them is to do the things you really love to do. He does not like the only real values, more like something consistent with their values.

In his view, now going to do big things users don't need, not much value in the Android platform. No matter how much a technical Bull, as long as the user is not interested, wouldn't have wanted to do. What he was doing was focusing on a feature.

Wang said UU safety isn't the only company to do something, but is only a focus to do this thing, and do the stability and integrity of the.

So far, UU safety this product has not been extended, even if has received two rounds of investments in United States dollars or a related article. "The value of a company is to obtain a very large amount of users, authorized users of products, and the product is of great value for users. "Wang Wei said.

Wang Wei, low-key doing their own products, low profile is not willing to disclose relevant information to people around, even if friends want to vote on the financing came in, he plans to do with their money.

"At least four or five years, mobile Internet security industry is not complacent. "Wang Wei told the reporter of Lei feng. Later improved the tone said, "you toss in one place all these years. Kill processes, the key is to kill the process doesn't work without permission can not kill the process! And then get to the battery doctor, cannot interfere with power consumption without permission, how can it be power?! These are not pure fool people?! Now the mobile industry is a weight-loss drug industry, if you eat a diet pills to lose weight, how those stars so hard to lose weight?! Useless key is diet pills, weight loss to eat less and exercise more. Security software is also like this, form only for the phone under the battery, clean up junk files, phone memory, ineffective, and mobile security has to do with it?! " Jack Spade iPhone 5 Case

A "shell" after Wang Wei to restore calm, made a conclusion: "on the user's mobile phone is used more and more, especially related to pay and when there is much more about privacy, mobile phone security becomes even more important. This is the only way in the future (UU protection mode) can go, and I'm going to do this thing. "

A final profit is to inject into the business model, according to Wang Wei, said, there is no fixed model, but very reliable advertising to recognize patterns. If a company can really succeed depends in the end will bring value to users.

Wang Wei said, "UU security is the only way to ensure phone safety in the future, safety is the most basic application, how such a company would have no value? "

According to his plan, after collaboration with the well-known mobile application store, green software.

After Ren Yuxin phone Butler against the micro

Tencent phone steward incorporation Tencent applications Center? The news has not been confirmed by the Tencent official, comprehensive news credibility has more than 80%. In fact it is also ripe for initiative: obviously, Ren Yuxin took charge of Tencent MIG did for a second "ticket" force, logic clearly for Tencent's mobile Internet business set up a primary revenue model. Hello Kitty Samsung Note 3 case

Tencent's mobile Internet business group (MIG) adjustment is far from over. This morning the news that Tencent applications Center Butler a whole into Tencent's handset sector, detailed arrangements will be announced later today. Tencent did not respond directly on the matter, and Tencent Tencent phone Butler Department application centers are just saying "will be adjusted in the near future."

No matter what the specific adjustments, one thread of logic are clearly visible.

Ren Yuxin succeeded Liu Chengmin controlled MIG since many media that MIG has the dust settled. But that is not the case.

Ren Yuxin Tencent can do on revenue to operators mobile Internet business group, both within and outside the Tencent don't thoughtful. Lei Feng pony tickets on the network analysis, think Ren Yuxin in MIG's task is to get at least a second ticket, and to ensure that most of Tencent's business "whole boat" and avoid micro-dominance, in turn, believed to be in the field of mobile Internet package Tencent's business. Also, if Ren Yuxin to MIG successfully build revenue models, which in turn will better promote the commercialization of the app.

It sounds more or less like MIG will confront origin CDG (corporate development group) app. Yet if Tencent Tencent phone Butler did accept command of the Department of the Centre, this confrontation is more obvious.

Tencent applications Center's advantage is to have a mass of third party application developers, and has formed a preliminary ecological. Tencent's open strategy two years ago, there have been many application developers in the company get a hefty return on the Center. Tencent applications Center itself, based on developers and users the advantages of Android applications on the issue with great voice.

https://www.youtube.com/watch?v=Nv6oLEeBxb4

Then the power of the industry's most challenging Tencent applications Center is what? Happens to be the app. Hello Kitty Samsung Note 3 case

The app open platform of public accounts, provides another kind of mobile Internet development solutions--developed before the APP, might as well do a micro public accounts to try. Micro platform can achieve most of the functionality of the APP, and at a low cost and effective access to seed user data. Micro-hot public platform with this developer-oriented solution has something. Appears to be, this solution is going to form an independent ecosystem.

Micro letter as the most successful mobile Internet platform virtually, with terminals, users, developers, and distribution channels. Naturally, the eco can subvert the most APP distribution channels--also including Tencent applications Center.

But if Tencent phone Butler-headquarters, several resources, including Tencent applications Center, the situation is different. Tencent Butler has a Terminal in mobile, Tencent applications Center developers and distribution channels, while Tencent QQ space, wireless portals and mobile QQ users. When these forces are coming together in time, it seems, can compete with micro-down.

With Tencent phone Butler as the core, integrated MIG and the power of other departments of the company, can form the public accounts better developer than a micro-ecosystem. Whether third-party developer support is application distribution service, Tencent is bound to do better than it is now. But objectively speaking, micro open platform of public accounts were not so friendly, many developers expected functions (such as subscriber management, and so on) also can't be on the line. So MIG can throughout the app on a mobile Internet market.

Most importantly, integrated Terminal, developer, user, and distribution channels will soon establish a mature business model, MIG's revenue levels improved significantly. This is Ren Yuxin job tasks.

To sum up, around the core of Tencent phone Butler resource allocation adjustments are a matter of course follow. Of course after this action will continue.

But another question emerged: Ren Yuxin to take another blockbuster MIG QQ browser do? Does he really had to bow to the UC? There are more surprises after the?

Tencent MIG trends for the year ahead was more exciting, worth the wait.

Samsung new Windows Tablet like most of the Surface

　　Since Microsoft launched since the Tablet Surface, many traditional OEM manufacturer seems to have finally found the "right direction." Whether Lenovo, HP, Dell, or Google and Apple, are inspired by the Surface must-especially combined flat base, detachable keyboard, and stylus. And now, according to the revelations of God @evleaks (Evan Blass) information disclosed, Samsung is about to launch a Windows Tablet, also refers to the Surface of the design concept.

　　If the message mark, then the Samsung Galaxy TabPro s the name sounds a little awkward, because Samsung will usually use it in Android product line.

　　Of course, this name is probably Samsung over the years for Windows Mobile phones and tablets are not so important a reason.

　　If Samsung determines the Galaxy brand for Windows product, may signal the company's Windows 10 more bullish. In addition, Samsung mercy Android and Microsoft patent dispute is over 1 year.
