German scientists have developed computer models predict the spread of infectious diseases According to Xinhua: German scientists have recently developed a computer model to predict the global spread of infectious diseases, which is characterized by the combination of the local infection dynamics and simulation of global civil aviation transportation network. Germany's Max Planck Society has said a press release, this model jointly developed by the Göttingen Max Planck Institute for Fluid Research Institute and the University of Göttingen, it can not only describe the global spread of infectious diseases, and the use of computer simulation technology, can also predict development of the epidemic, especially the prediction may have been particularly threatened areas. The researchers launched for the propagation behavior of pathogens. They first developed a dynamic model of epidemic infection by air travel between the two different transport hub, and transmission to other passengers. In the model, the researchers counted more than 2 million times a week flights between 500 airports around the world, covering about 95 percent of the global civil aviation transportation. The geographical spread of infectious diseases through the analysis of the liquidity situation of the global air passenger forecasts. In this way, researchers, London, New York and Frankfurt and other major aviation hub in a heavy responsibility in the process of the rapid spread of infectious diseases, In contrast, the pathogen first appeared locations has little to do. In addition, the spread of infectious diseases, the transport hub of the city's airport scale much smaller than the airport route dense extent. The communique says that the model is a random differential equations, the dynamic description of the epidemic spread and infection. The model parameters and disease-related values, such as infected individuals, the average caused by secondary infection of quantity, the cure rate and mortality. 2003 SARS outbreaks, pathogens can quickly spread out around the world through modern aviation network. This new model during the global SARS outbreak last year about the experiment, the result is very consistent with the actual spread of the epidemic. Previously, infectious diseases, mathematical standard model is a diffusion process to describe the epidemic spread of this diffusion process and the diffusion of molecules in the fluid and react chemically with other molecules is very similar. The researchers believe the new model will help reduce damage and casualties in humans to deal with the new epidemic. Before the implementation of the vaccine and control measures in the computer model the effectiveness of various prevention strategies for testing and comparison. As the fast spread of the epidemic today the emergence of such predictions has great significance. www.perfume.com.tw/bags/Attachments:

Rely on the teeth, answer the phone, to see things with his tongue, and listening to music through the temple To see things your eyes, listen to the sound use ear-year-old child also know that common sense, but modern technology can change this rule, some magical new civilization and even to change the function of our five senses. Tongue: to help blind people see the world University of Wisconsin researcher Paul recently developed a "tongue display system. Experiment, the researchers will be a healthy people blindfolded, placed in its mouth contact of a flat, let tongue against the Researchers through a special current images of objects on the electronic signal is passed to the tongue, a few minutes later, the tongue nerve signaling to the brain, "the blind man can see before us the letters. The tongue was competent to pass members work on the distribution of a large number of tactile cells in the tongue is extremely sensitive to electrical stimulation, and the tongue of saliva secreted by the low voltage can achieve the smooth conduction of the current. The tongue can "see" letters, you can read, watch the world, in terms of the system with poor eyesight or blind, is undoubtedly a great boon. The experts pointed out that the short term, this system is expected to replace the blind letters. However, the effect of the perception of the system of things is not yet clear and needs further improve image clarity. Paul pointed out that "the tongue can not really replace the human eye," but this technique is the perfect will greatly improve the quality of life of the blind. Teeth: calm and collected to answer the phone If the long tongue eye surprising, then teeth, long ears "is even more incredible. Products exhibition organized by the Science Museum in London not long ago, a new invention called a body trusted device "has attracted a lot of attention. Use the phone a friend how much encountered such a dilemma: the phone is a lost and then lost, suddenly a bell rang in the meeting, and so on. London's Royal College of Art graduate James and Jim design "tooth phone" is expected to solve these problems. The small size of the device consists of two parts: vibration device and a wireless receiver. The receiver can receive the digital signal coming from the radio and mobile phones. The voice information through the vibration device into sonic vibrations pass to the skull, and ultimately by the teeth, the inner ear to the acoustic information is received, will revert to the original sound. Since this vibration is at the molecular level, not only did not murmur, clear sound, and even if you open your mouth will not affect others. Reportedly, the "tooth phone" can not only answer the phone, listening to music, but also listen to the voice of the Internet system. The experts say, some hard of hearing people can take advantage of the "tooth phone" to improve hearing. This device has a wide application prospect such as spies to receive secret instructions or Athletes in the training process to accept the coach conductor. However, the "tooth phone" there are drawbacks: First, it requires professional dental surgery, implanted teeth to use. Moreover, this device can only "listen" can not "say". Temple: listening to music underwater MP3 player for many people is nothing new, but a student of the Department of English at Brunel University Design, Sam? James invented an underwater temple to listen to music playback system. James is a swimming enthusiasts can listen to music while swimming. May be present, no matter how advanced music player can not be used in the water. So he designed a MP3 player, not afraid of water. James will be the core device of the player - the drive is installed in the goggles of the temple, and make the player and goggles combined. When a player to play music, the music will drive oscillation, directly into the inner ear through the skull by the temple. In this way, the sound transmission completely through the outer ear. In the water, the conventional technology can not bypass the ear canal, the surrounding environment arising from the noise will enter the outer ear, the quality of the impact of music listening. Underwater listening experience unexpectedly be greatly improved. This invention, there are many other advantages. For example, in the long-distance exercise, if you are using a traditional player, a big sound on to hear any sound around, switch to such a device while listening to music, but also hear the sound of passing traffic, which greatly improve security in the exercise. In addition, studies have shown that moderate oscillation can promote bone growth. It can also be further developed into a professional underwater communication products, has broad application prospects. www.perfume.com.tw/ornament/Attachments:

British scientists to create a monitoring system: they predicted that terrorist British scientists have developed an incredible monitoring system, it can be identified within seconds from the sea of suspected "terrorists", which predicted terrorist! " However, questions about which students - one not yet made any "terrorist action", and it is still counted as "terrorists"? According to reports, this new monitoring system can be predicted that terrorist "named" Intelligent Walker surveillance, jointly developed by the South London's Kingston University and Ipsotek technology companies. Ipsotek competent Ken Moore said the magic of the IPS system is that it can almost read the terrorists inside thinking "General, can within seconds from the big crowd to identify the suspected" terrorists ". According to reports, the IPS system is enabled, connected to it and the existing surveillance cameras across the UK, the use of an advanced program to analyze the images taken by the monitor. During the analysis, the pedestrian moving pictures photographed by the monitor will be simplified as a series of pixels, and compared with the pre-set data in the computer. Once the software comparisons, I found the screen a person's actions "different" - for example, a person in Buckingham Palace or a government building potential "target building" around aimlessly wandering for a long time, the monitoring center The computer will automatically sound the alarm. Immediately, the duty officer can visit the suspect on the computer screen enlarged, more detailed inspection of the replay the video of his previous activities. Allegedly, the IPS system magnification up to 400 times, even suspect, eyebrows, beard can be seen clearly. After a series of recognition, if the duty officer feel the need, and will notify the police or plainclothes officers to take action. Ipsotek company said, the IPS system has basically developed, will be fully completed within two months. It is reported that a district in London is using the IPS system to monitor the activities of prostitution and street crime. Analysts predict that the application of the IPS system may lead to more such as the infringement of citizens' privacy controversy is bound to have some innocent citizens by the monitoring system is designated as "terrorists" in the column: You can imagine, if a citizens at the mall, hang out too long, he will become a suspected "terrorist"! In addition, a paradox of Health - For a people who have not made any "terrorist action", is also referred to as "terrorists"? In any case, at least one thing is certain: using the IPS system, Buckingham Palace and the Capitol may be a safer place. www.perfume.com.tw/ornament/Attachments:

The latest discovery and innovation: Silk woven skin is expected to replace autologous skin graft. Skin graft after skin deep burn patients can be described as "robbing Peter to pay Paul" Even so it is difficult to completely restore the original appearance of the skin and function. However, the reporter learned from the just-concluded China International Silk Conference, these traditional autografting may be lovely silk of silkworms secreted protein to replace, specifically, is the silk fibroin and sericin by scientists Cherish "conjure up" the skin, bones, blood vessels. According to reports, the Institute of Materials Engineering of Suzhou University more than a decade in the silk proteins of biomedical research areas frequently breakthrough: to be included in the national "863" high-tech silk protein artificial skin was developed in the second half of last year, and in animal experiment to achieve the desired effect, will enter the clinical research stage. The artificial skin of silk protein using the principle of tissue engineering, high-tech natural silk fibroin from the development as the main raw material, has good biocompatibility, for the treatment of deep burn wounds, with our own intellectual property rights been a number of national invention patent protection. At the same time continue to carry out medical research of the silk fibroin, the School of Biological Materials Task Force again aimed at the right like magic sericin. Sericin is composed of 18 amino acids of the natural water-soluble globulin. Sericin in silk production, is used as a waste discharge, this is not only a huge waste of resources, can also cause environmental pollution. The researchers found in the study The sericin biodegradable better than the silk fibroin, that is, When sericin become the carrier of cell proliferation and tissue regeneration and to complete the task, the more susceptible to human tissue absorption. The development of new materials can not only broaden the use of silk, and promote artificial tissues, artificial organs, sericin turning waste into treasure the coup. Currently, the group has successfully prepared porous sericin materials, is embarking on the structure and performance. www.elady.tw/gift/Attachments:
