Background Tuberculosis (TB) is the second-most common cause of death from infectious disease (after those due to HIV/AIDS). Roughly one-third of the world's population has been infected with M. tuberculosis, with new infections occurring in about 1% of the population each year. People with active TB can infect 10-15 other people through close contact over the course of a year. Materials and ...

A collection of orthonormal bases for a d × d Hilbert space is called mutually unbiased (MUB) if for any two vectors v and w from different bases the square of the inner product equals 1/d: |〈v, w〉|2 = 1 d . The MUB problem is to prove or disprove the the existence of a maximal set of d+1 bases. It has been shown in [W. K. Wootters, B. D. Fields, Annals of Physics, 191 no. 2, 363-381, (1989)] t...

We propose an efficient communication protocol for multimedia data delivery in high-speed multichannel networks. Multimedia traffic is generally categorized into two types: real-time traffic and delayable traffic. High-speed multichannel networks refer to the third-generation computer networks, e.g., WDMA networks, with high-speed parallel multichannels to be able to support multiaccess communi...

AMONG the numerous advantages promised by a well constructed Union, none deserves to be more accurately developed than its tendency to break and control the violence of faction. The friend of popular governments never finds himself so much alarmed for their character and fate, as when he contemplates their propensity to this dangerous vice. He will not fail, therefore, to set a due value on any...

wars begin to supply some goals. they have many predictable and unpredictable costs. state leaders and military commanders try to find way to decries war damages and to choose suitable strategies to reach their objectives spending fewer costs. one of these strategies can be blitzkrieg. this essay tries to explain the way of using this strategy in 20th century wars describing its theoretical bas...

Judgments about the perceptual appearance of visual objects require the combination of multiple parameters, like location, direction, color, speed, and depth. Our understanding of perceptual judgments has been greatly informed by studies of ambiguous figures, which take on different appearances depending upon the brain state of the observer. Here we probe the neural mechanisms hypothesized as r...
