According to the Reuters dyslexia (dyslexia) is that many students problems, may also be unaware of the source of one of the parents blame their children. Frequently written typos, confused characters with similar shapes, the general cognition is due to congenital abnormalities in the brain structure. Improvements can be made through training, but there has been no cureable solution.
But a group of French scientists claim that they may have found a physiological cause of dyslexia – the answer lies in the patient's eyelids and comes up with a relatively simple treatment.
In patients with dyslexia, the cones of both eyes are symmetrical, causing confusion in the brain.
The literacy puzzle is hidden in the eye
Like the left and right scorpions, human eyes also have primary and secondary points, most of which use the right eye as the dominant eye. When you look at things, the images received by the primary and secondary eyes are slightly different. In the middle of the eye, the image will produce a better image, and the image quality of the other eye will be slightly worse. The brain will "integrate" and produce a single image.
In general, the cone cells responsible for receiving image signals are arranged in a circular shape in the main eye and irregularly arranged in the other eye. Two French scientists, Albert Le Floch and Guy Ropars, published a study in the journal Proceedings of the Royal Society B, found that the cones of both eyes of dyslexic patients are also arranged in a circular shape. In disguise, the eyes compete with each other for the role of the main eye. The brain produces so-called "mirror errors" under chaos, which confuses the patient's vision, so that similar shapes such as "b" and "d" are similar, but The case of the opposite direction of the letter.
Patients with dyslexia will confuse glyphs and letters.
High-speed flash treatment with LED lights
The problem of dyslexia patients, because there are two identical images messing up the brain, means that only one of the images can be offset to solve the problem.
The researchers found that when the two images were passed to the left and right brains of the patient, there was a lag of about 10,000 minutes, so they came up with a high-speed flash of LED lights that could not be seen with the naked eye, eliminating the overlapping images that plagued the patient. As a result, the brain has only one image left, so that they can read normally.
John Stein, a professor at the University of Oxford and a consultant to the British Association for the Study of Dyslexia, said the study was quite interesting because studies on dyslexia in the past have focused on the visual aspects of patients, while highlighting the main eye. The importance of receiving images from the brain. The only flaw is that this study did not explain the different causes of the arrangement of cone cells.
Dyslexia is the most common problem of learning disabilities in the world. The number of affected people is different. There are 3% to 7% of people affected. It is also said that up to 20% of the population have different levels of dyslexia.

Compared to single band, the most competitive advantage of dual band is the equipment can work along with 2 bands together at the same time. This enlarges the application range of the equipment and allows it to fucntion under multi conditions, which is way better than the single band one.
Nowadays, with the development of the econimics, more and more countries started to build up the PON (Passive Optical Network) instead of working with the AON (Active Optical Network). The former obviously possesses more advantages than the latter, which is due to not only the non-power-required characteristic but also the advanced technologies.
The ONU has two functions: it selectively receives the broadcast sent by the OLT, and responds to the OLT if the data needs to be received; collects and buffers the Ethernet data that the user needs to send, and sends it to the OLT according to the assigned sending window The end sends the buffered data. The application of ONU can effectively improve the uplink bandwidth utilization of the entire system, and it can also configure the channel bandwidth according to the network application environment and applicable service characteristics to carry as many end users as possible without affecting the communication efficiency and communication quality, and improve the network utilization Rate and reduce user costs.
