Neurocomputing: picking the human brain

Article Abstract:

'Neurocomputing' involves nonprogrammed adaptive information processing systems - otherwise known as 'neural networks' - to develop associations (transformations or mappings) among objects, responding to environments. A neurocomputer - hardware that implements a neural network - is fundamentally different from traditional computing hardware, which does 'algorithmic' computing. A neural network does not follow a step-by-step procedure, but compares examples and results, so that the network 'teaches' itself. A neural network is modeled on the structure of the brain, with 'nerve cells', each of which is connected to many others. Algorithmic computing and neurocomputing complement each other: the first is good for accounting and modeling tasks; the second is good for pattern recognition, fuzzy logic, and adaptive control. Some relevant publications are mentioned and described.

Discovering the Occidente

Article Abstract:

The rich prehistory of West Mexico consists of great artifacts of stone, ceramic, and jade, yet scholars know little about the people who inhibited this region. These people had cultural and religious ties with their neighboring Mesoamerican people, but they stand alone in their artistry. Scholars found 32 burial sites that reveal more information about these people but many sites are looted for ornamental figures. One tomb in Huitzilapa was built under a house and consisted of many human remains. Scholars are still discovering more information about the history of West Mexico.

Clear the air: ventilation systems help reduce the risk of TB infection

Article Abstract:

Tuberculosis (TB) infections are common in emergency rooms because of inadequate ventilation and overcrowding. TB can be caught by droplet infection and inadequate ventilation could be one of the leading factors promoting its spread and prevalence. Proper mechanical system design is one way of ensuring protection from airborne TB and programs can be augmented by identification, isolation and treatment of TB patients.
