次生代谢产物异黄酮是一类主要在豆科植物中合成的多酚类物质。异黄酮不仅利于豆科植物应答生物和非生物胁迫、诱导根瘤形成等,而且对人体具有重要的保健和药用价值,比如预防和治疗癌症、心脑血管疾病和骨质疏松等。大豆是工业化生产异黄酮的重要来源,主要含有12种异黄酮物质及其衍生物。根据其化学结构的差异,可将其分为游离型苷元(aglycone)和结合型糖苷(glycoside)两大类,其中结合型糖苷占异黄酮总量...
Improving the sensitivity of protein-protein interaction detection and protein structure probing is a principal challenge in cross-linking mass spectrometry (XL-MS) data analysis. In this talk, we pro...
Background: Early rapid weight gain is associated with later overweight, which implies that weight centile crossing tracks over time.

Negative feedback is a universal control mechanism that lets a system’s output throttle its input. If an engine revs up, negative feedback tapers its power source. But if the engine slows down, it re-...
The «prediction» and «forecast» of the critical frequency of the F 2 layer (f0 F2 ) is an important issue for frequency planning in short wave radio communications. In this context...
In this paper we study multi-input multi-output (MIMO) linear time-invariant (LTI) control systems. We show that some well known constraints on the performance of single-input single-output (SISO) lin...
The authors consider the problem of wafer temperature control in rapid thermal processing (RTP) of semiconductor wafers. They present a novel approach to the analysis of candidate sensor configuration...
For linear systems with delays, we define a new class of Lyapunov-like functionals that may be used to prove stability. We also show how we may design a stabilizing (delayed) state feedback for delay ...
e fact that the capacity region of the discrete memoryless physically degraded broadcast channel is not increased by feedback is establisked.
The gamma-entropy is a convex function of matrices that is closely related to the Frobenius and spectral (maximum singular value) norms. It comes up in several applications such as central H-infinity ...
This paper shows that Lyapunov-based state feedback controller synthesis for piecewise-affine (PWA) slab systems can be cast as an optimization problem subject to a set of linear matrix inequalities (...
We consider a continuous-time linear system with sampled constant linear state-feedback control and a convex quadratic performance measure. The sample times, however, are subject to variation within s...
The abundance and fecundity of life on this planet is directly related to the energy supplied by the sun. The pyramid of life starts with the absorption of a fraction of this energy, followed by its c...
We consider the problem of constructing decentralized control systems. We formulate this problem as one of minimizing the closed-loop norm of a feedback system subject to constraints on the controller...
