Modeling the Interaction Between Leaders and Society During Conflict Situations

This paper describes an effort by Sandia National Laboratories to model and simulate populations of specific countries of interest as well as the population’s primary influencers, such as government and military leaders. To accomplish this, high definition cognition models are being coupled with an aggregate model of a population to produce a prototype, dynamic cultural representation of a spec...

Interaction between Intestinal Microbiota and Serotonin Metabolism

Gut microbiota regulates the production of signaling molecules, such as serotonin or 5-Hydroxytryptamine: 5-HT in the host. Serotonin is a biogenic amine that acts as a neurotransmitter in the gut and brain. There is a perfect interaction between human gastrointestinal microbiota and the serotonin system. The gut microbiota plays an important role in the serotonin signaling pathways through the...

Laser physics and laser-tissue interaction.

Within the last few years, lasers have gained increasing use in the management of cardiovascular disease, and laser angioplasty has become a widely performed procedure. For this reason, a basic knowledge of lasers and their applications is essential to vascular surgeons, cardiologists, and interventional radiologists. To elucidate some fundamental concepts regarding laser physics, we describe h...

How computational physics is uniting science and revolutionizing society

Computers are now much more than tools for analysis. They provide us with innumerable intellectual challenges, ranging from algorithm development to allowing us to explore novel concepts such as self-organized criticality. Simulational science in particular continues to grow as a major subfield. Three-dimensional studies ranging from fluids to dynamical molecular systems are becoming routine. I...
