Function Spaces and Capacity Related to a Sublinear Expectation: Application to <Emphasis Type="Italic">G</Emphasis>-Brownian Motion Paths

In this paper we give some basic and important properties of several typical Banach spaces of functions of G-Brownian motion paths induced by a sublinear expectation—G-expectation. Many results can be also applied to more general situations. A generalized version of Kolmogorov’s criterion for continuous modification of a stochastic process is also obtained. The results can be applied in continuous time dynamic and coherent risk measures in finance, in particular for path-dependence risky positions under situations of volatility model uncertainty.

Bipolar electrochemistry in confined nanospace

正Nanopores employ a confined space for electrochemical sensing of high-throughput individual biomolecules in solution.The most general mechanism of nanopore sensing is based on a volume exclusion effect.However,the increasing demands on revealing the single-molecule/particle chemistry and biophysics require the nanopores not only provide structural/conformational/sequencing information,but also     

一种快速校准GC–MS仪的色谱参数设置方法

介绍一种快速校准GC–MS仪的色谱参数设置方法。该方法进样口温度及传输线温度均设置为280℃,对不同长度的色谱柱采用不同的升温速率(以八氟萘为例15,30 m柱升温速率分别为20,40℃/min)。与校准规范提供的参考方法相比,该方法能节约时间1 h以上,在12台仪器上进行验证测试,八氟萘和硬脂酸甲酯的色谱峰形均较好,且出峰时间分别缩短了13.5,7.75 min(30 m柱)。该方法比校准规范中的参考方法具有更好的适用性,能用于不同型号该类仪器的计量校准。     

A subspace fitting algorithm of acoustic vector sensor array and corresponding matrix pre-filter design

In order to ease the pass-band response distortion of the matrix pre-filter,a simple approach for designing matrix spatial filter is proposed,which minimizes the sum of the k maximal distortion norm（k is the number of the constraint points）within the pass-band,while constraining the filter response within the stop-band.Considering the costly amount of calculation of the high-resolution methods,an algorithm with small amount of calculation based on matrix pre-filtering and subspace fitting using acoustic vector array（MF-VSSF）is proposed.Through joint processing of signal subspace of both pressure and particle velocity,the pre-filtering matrix and the signal subspace is decreased to M-dimensional（M is the number of array-element）,hence reduces the time-consumption of the matrix pre-filter design and DOA searching.Simulation results show that,the method offers the same performance as MUSIC with pre-filtering,but has much lesser amount of calculation.Moreover,the designed prefilter can efficiently suppress the interference in the stop-band and improve the estimation and resolution performance of successive DOA estimators.

A new pH fluorescent molecular switch by modulation of twisted intramolecular charge transfer with protonation

A pH fluorescent molecular switch, BOPIM‐dma, a boron 2‐(2′‐pyridyl) imidazole complex derivatives, was investigated in aqueous system. BOPIM‐dma shows weak or no fluorescence in conventional solvents due to twisted intramolecular charge transfer (TICT). Upon protonation of the dimethylamino groups in BOPIM‐dma, its fluorescence was turned on ascribed to the inhibition of TICT. Its emission can be switched ‘on’ or ‘off’ between pH 2.4 and 4.0, and it undergoes a reversible protonation–deprotonation reaction with a pKa of 3.12. Copyright © 2013 John Wiley & Sons, Ltd.
