As the power of modern computers grows alongside our understanding of the human brain, we move ever closer to making some pretty spectacular science fiction into reality. Imagine transmitting signals directly to someone's brain that would allow them to see, hear or feel specific sensory inputs. Consider the potential to manipulate computers or machinery with nothing more than a thought. It isn't about convenience -- for severely disabled people, development of a brain-computer interface (BCI) could be the most important technological breakthrough in decades.

BCI systems measure brain activity through sensors and use signal processing and machine learning to interpret cognitive states. BCI can be used for communication, control of prosthetics, and other applications. However, challenges include low signal-to-noise ratios, limited transfer rates, and variability between individuals. Adapting BCI systems based on individual user characteristics such as age, physiology, and skills could improve performance by matching technologies to users. More research is needed to understand these relationships.

Brain Waves Surfing - (In)security in EEG (Electroencephalography) Technologies
Electroencephalography (EEG) is a non-invasive method for the recording and the study of electrical activity of the brain taken from the scalp. The source of these brain signals is mostly the synapic activity between brain cells (neurons). EEG activity is represented by different waveforms per second (frequencies) that can be used to diagnose or monitor different health conditions such as epilepsy, sleeping disorders, seizures, Alzheimer disease, among other clinical uses. On the other hand, brain signals are used for many other research and entertainment purposes, such as neurofeedback, arts and neurogaming. Nowadays, this technology is being adopted more and more in different industries.
A brief introduction of BCIs (Brain-Computer Interfaces) and EEG will be given in order to understand the risks involved in our brain signals processing, storage and transmission.
Live demos include the visualization of live brain activity, the sniffing of brain signals over TCP/IP as well as flaws in well-known EEG applications when dealing with some corrupted samples of the most widely used EEG file formats (e.g. EDF). These demos are a first approach to demonstrate that many EEG technologies are prone to common network and application attacks.
Finally, best practices and regulatory compliance on digital EEG will be discussed.

Seven ages
All the world’s a stage,
And all the men and women merely players;
They have their exits and their entrances,
And one man in his time plays many parts,
His acts being seven ages. At first the infant,
Mewling and puking in the nurse’s arms;
And then the whining schoolboy, with his satchel
And shining morning face, creeping like snail
Unwillingly to school. And then the lover,
Sighing like furnace, with a woeful ballad
Made to his mistress’ eyebrow. Then a soldier,
Full of strange oaths, and bearded like the pard,
Jealous in honor, sudden and quick in quarrel,
Seeking the bubble reputation
Even in the cannon’s mouth. And then the justice,
In fair round belly with good capon lined,
With eyes severe and beard of formal cut,
Full of wise saws and modern instances;
And so he plays his part. The sixth age shifts
Into the lean and slippered pantaloon,
With spectacles on nose and pouch on side;
His youthful hose, well saved, a world too wide
For his shrunk shank; and his big manly voice,
Turning again toward childish treble, pipes
And whistles in his sound. Last scene of all,
That ends this strange eventful history,
Is second childishness and mere oblivion,
Sans teeth, sans eyes, sans taste, sans everything.
Prevention and treatment of cancer
Cancer is when abnormal cells divide in an uncontrolled way.
Prevention:
Stop using microwave.
Say no to plastic.
Golden milk.
Don't use foil paper.
Active lifestyle.

Different types of waves
Every sound we hear, every photon of light that hits our eyes, the movement of grass blown by the wind and the regular beat of the tides are all examples of waves. They are all around us. Visible, physical wave*s such as those we see when a rock is thrown into water are what many people think about when they first began to think about waves. These waves have distinct properties specific to their type but also exhibit characteristics in common with more abstract waves such as sound waves and light (electromagnetic) waves.

留信认证全称全国留学生信息服务网认证,隶属于北京中科院。①留信认证门槛条件更低,费用更美丽,并且包过,完单周期短,效率高②留信认证虽然不能去国企,但是一般的公司都没有问题,因为国内很多公司连基本的留学生学历认证都不了解。这对于留学生来说,这就比自己光拿一个证书更有说服力,因为留学学历可以在留信网站上进行查询!
B.为什么我们提供的毕业证成绩单具有使用价值？
查询留服认证是国内鉴别留学生海外学历的唯一途径，但认证只是个体行为，不是所有留学生都操作，所以没有办理认证的留学生的学历在国内也是查询不到的，他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单，就有了使用价值。
