摘要： An automatic early warning method and system is for a pressure ulcer prone part of a human body. The method includes: constructing a matrix diagram by using marks with variable states; receiving a pressure signal from a pressure sensor matrix laid in an area that a body of a patient is frequently in contact with; corresponding each miniature ultra-thin dynamic pressure sensor contained in the pressure sensor matrix to each mark in the matrix diagram respectively; after receiving a pressure signal indicating that the pressure at a part in contact with the patient, sensed by the pressure sensor matrix, is greater than or equal to a critical value, changing the state of the marks in the matrix diagram, corresponding to the miniature ultra-thin dynamic pressure sensors in the pressure sensor matrix sensing that the pressure is greater than or equal to the critical value, into an early warning state.

摘要： Disclosed is a concrete product incorporating rubber aggregate produced by casting under pressure. The concrete product may optionally be cast at 6.9-27.7MPa for periods of, for example, 24 hours. In one embodiment the rubber aggregate may comprise coarse and/or fine rubber aggregate to replace natural sources of coarse and fine aggregate. Casting under pressure was found to generally improve the performance characteristics of the concrete when compared to corresponding concrete cast without pressure.

摘要： A sequential auction method based user association scheme in downlink heterogeneous cellular networks is provided to better utilize available radio resources and simultaneously maintain user QoS requirements. A sequential second-price auction game that allocates users to base stations in repeated iterations is introduced. A valuation function formulation for participating buyers to respect user QoS requirements is proposed, and a game mechanism with unit demand buyers and myopic bidding strategies that encourages traffic offloading is introduced. Furthermore, the ordering of distinct users that provides an approximation to socially efficient outcomes is investigated. Numerical results validate the effectiveness of the proposed method and show significant rate gains for cell edge users.

摘要： A novel 2, 2' -bipyridyl oxime, kibdelomycin A was isolated from the broth culture of a rare actinomycete strain Kibdelosporangium phytohabitans XY-R10. Its structure was established by extensive 1D and 2D NMR and high-resolution mass spectral analyses as well as single-crystal X-ray diffraction analysis. This natural product demonstrated a broad spectrum of algicidal activities. In addition, kibdelomycin A possesses lower toxicities compared with Copper sulfate Therefore, kibdelomycin A could potentially serve as an efficient and environmental-friendly algicide in controlling harmful algal blooms.
