Lice, Humans, and Microbes
Lice are small, wingless, minor ectoparasites of mammals and birds. More than 540 blood-sucking lice (Phthiraptera: Anoplura) have been described with each host having its own type of louse, suggesting the cospeciation of the lice species with their host. Among these, two lice species from two different genera infest humans: Pediculus humanus and Phthirus pubis (pubic “crab” l...
متن کاملReal-Time Humans Detection in Urban Scenes
We address the issue of real-time pedestrians detection in a urban environment. This is a challenging task owing to the high variability of appearances and poses that humans can have and to the complexity of backgrounds. We propose a solution made of gradient-based local descriptors combined to form strong classifiers and organized in a cascaded detector. We developed for this an extension of t...
متن کاملMolecular switches and cages
Chemists have developed a large number of synthetic switches, complementing the many types found in nature. Given their prominence in biology, it is not surprisingly that photoswitches, which are actuated by ultraviolet, visible or infrared light, have been an especially productive field of study. Despite their long history, new types of synthetic photoswitches continue to emerge and “old frien...
متن کاملBats, viruses, emerging diseases and humans
This paper reviews the unique characteristics of bats, their important roles in providing ecosystem services, their viruses in relation to emerging diseases. Bats, as flying mammals, are the second largest order following rodents, with a wide variety (over 1400 identified species among 230 genera of 21 families in the world) due to their flying power and echolocation. Despite their importance a...
متن کاملGauges and Cages . Part II
D denotes a non empty subset of E 2 T , and C denotes a compact connected non vertical non horizontal subset of E 2 T. We now state the proposition (1) For all sets A, B such that for every set x such that x ∈ A there exists a set K such that K ⊆ B and x ⊆ K holds A ⊆ B. Let m be an even integer. Note that m + 2 is even. Let m be an odd integer. One can verify that m + 2 is odd. Let m be a non ...
