超导性 可持续发展 大型强子对撞机 新超导链接
2023/5/26
The Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator, is also the largest single machine operating in the world today that uses superconductivity. The proton bea...
耳蜗中tip-link张力与静纤毛运动动力学研究
静纤毛 变形体 tip-link张力 频率特性
2022/3/28
诠释耳蜗的主动感音放大机制一直是未解的医学难题。这种机制与耳蜗中外毛细胞顶端的静纤毛运动密切相关，静纤毛运动又受到tip-link张力与淋巴液流体力的调节。因此，研究静纤毛运动过程中tip-link张力是诠释耳蜗的主动感音放大机制的重要环节。本文把静纤毛视为变形体，基于泊肃叶流动理论并结合分布参数模型，推导了静纤毛运动的解析解。研究了盖膜剪切荷载作用下静纤毛和淋巴液相互作用的动力响应以及tip-l...

The characterisation of a HF channel by means of monthly electron density profiles can be complemented with a detailed study of radio propagation «worst cases» on situations with extremes co...
MINIMUM LATENCY LINK SCHEDULING FOR ARBITRARY DIRECTED ACYCLIC NETWORKSUNDER PRECEDENCE AND SINR CONSTRAINTS
Minimum latency link scheduling SINR model physical interference model
2012/12/4
Scheduling wireless links under the SINR model has attracted increasing attention in the past few years [1–6, 8–15, 18–20, 23–25, 27, 28, 33–36, 39, 41, 42, 45, 46]. However, most of previous work did...
Abstract—We show a simple method for constructing an infinite family of graph formation games with link bias so that the resulting games admits, as a pairwise
stable solution, a graph with an arbitra...
A Link Between Black Holes and the Golden Ratio

2011/8/31
We consider a variational formalism to describe black holes solution in higher dimensions. Our procedure clarifies the arbitrariness of the radius parameter
and, in particular, the meaning of the eve...
Aging is a fundamental aspect of living systems that undergo a progressive deterioration of physiological function with age and an increase of vulnerability to disease and death. Living systems, know...
Effects of Random Link Removal on the Photonic Band Gaps of Honeycomb Networks
the Photonic Band Gaps Honeycomb Networks
2010/11/16
We explore the effects of random link removal on the photonic band gaps of honeycomb networks. Missing or incomplete links are expected to be common in practical realizations of this class of connect...

Cascaded multiplexed optical link telecommunication network frequency dissemination
2010/10/21
We demonstrate a cascaded optical link for ultrastable frequency dissemination comprised of two compensated links of 150 km and a repeater station. Each link includes 114 km of Internet fiber simultan...
Microwave Signal Attenuation in Harmattan Weather Along Calabar-Akampkpa Line-of-Sight Link
Harmattan Radio signal Fog attenuation Statistics of fade Calabar
2010/4/13
Line-of-sight (LOS) attenuation at 6.44GHz was measured at Calabar (4° 58' N, 8° 17' E) for ten months (Aug '93-May '94) using the Nigerian Telecommunications radio signal. The measurement was made wi...
