In view of problems of low reliability, poor moisture resistance and short service life existed in electronic sensor beautiful u perfume applied in steel wire rope tension measurement of mine hoist, a fiber grating sensor was designed.The sensor uses dual-gate structure, and adopts differential compensation method to eliminate impact of temperature
Ranking search results is essential for information retrieval and Web search.Search engines need to not only return highly relevant results, but also be fast to satisfy users.As a result, not all available features can be used for ranking, and in fact only a small percentage of these features can be used.Thus, it is crucial to have a feature select
Abstract A many-body system in the vicinity of a first-order phase transition may get trapped in a local minimum of the free energy landscape.These so-called false-vacuum states may survive for exceedingly long times if the barrier for their decay is high enough.The rich phase diagram obtained in graphene multilayer devices presents a unique opport
Interleukin 4 (IL-4) induces B-cell differentiation and survival of chronic lymphocytic leukemia (CLL) cells.MicroRNAs (miRNAs) regulate mRNA and protein expression, and several miRNAs, deregulated in CLL, might play roles as oncogenes or tumor suppressors.We have studied the miRNA profile of CLL, and its response to IL-4, by oligonucleotide microa
In migratory species, the timing of arrival at the breeding grounds is a life-history trait with major fitness consequences.The cnd keep an opal mind optimal arrival date varies from year-to-year, and animals use cues to adjust their arrival dates to match this annual variation.However, which cues they use to time their arrival and whether these cu
