Driving time delays treatment initiation for tuberculosis in Uganda
We investigated the association between distance to health care facilities and delay in treatment initiation for patients with tuberculosis in Kampala, Uganda. We used a theoretical construct known as appraisal delay, which is the approximate time in
Understanding the behavior of fly larvae from neural activities in their isolated central nervous system
You may have heard about “The brain in a vat”, the philosophical scenario which talks about simulated reality and conceptions. It may sound bizarre and unrealistic. However, larval fruit fly neuroscientists literally perform the experiment to understand
Does intestinal inflammation impact the lung response to bacterial endotoxin?
Lung inflammation leading to airway hyperresponsiveness causes illnesses for more than ten percent of the population in USA. Recent research had indicated that patients with inflammatory bowel disease have higher incidence of airway hyperresponsiveness compared to the

Superradient and subradient emission of molecules coupled via plasmons
A physical dipole consists of two equal and opposite point charges. Atoms and molecules can be viewed like oscillating dipoles, picturing each atom as a tiny antenna emitting electromagnetic waves. The excited atomic states are relaxing to
