Gastrodia elata Blume (G. elata), a traditional Chinese medicine, is widely used for treatment of various neuro dysfunctions. However, its quality control is still limited to the determination of gastrodin. In the present study, two novel strategies based on quantitative evaluation of total gastrodin and gastrodigenin with base hydrolysis and total gastrodigenin with base-enzymatic hydrolysis f...

In this study, we analyzed the brightness temperature characteristics of short-duration heavy rainfall (SDHR) along Chengdu–Chongqing Railway (CCR), an important corridor economic and transportation activity in southwest China. Our findings could prove useful monitoring advance warning SDHR events: (1) predominantly occurred from July to August, with a peak frequency CCR area. terms diurnal var...

Abstract – We present a model for characterising the behaviour of the buffer at a base station router when TCP flow control is used in combination with a link layer retransmission protocol over a cellular wireless link. We show how our model can be used to predict packet latency, optimally dimension the buffer, and tune TCP to ensure maximum utilisation of the link, for specific wireless channe...

The interaction between isatin-β-thiosemicarbazone (IBT) and calf thymus DNA (CT-DNA) was investigated in physiological buffer (pH 7.4) using Neutral Red (NR) dye as a spectral probe by UV–Vis absorption and fluorescence spectroscopy, as well as viscosity measurements. The IBT is stabilized by intercalation in the DNA ( K [IBT –DNA] =1.03×105 M−1), and displaces the NR dye from the NR–DNA comple...

Thunderstorm activity over the Qinghai–Tibet Plateau (QTP) has important climatic effects and disaster impacts. Using thunderstorm feature dataset (TFD) established based on black body temperature (TBB) cloud classification (CLC) products of Fengyun-2E (FY-2E) geostationary satellite, as well lightning data World Wide Lightning Location Network (WWLLN), temporal spatial distributions some prope...

this study examined if pre-germination altered the water content and water activity, contents of phytate, total phenolic, (±)-catechin, quercetin and total antioxidant capacity of almond  (prunus dulcis)kernel. raw almond kernels were submerged for 15 hours in water, 0.02 mol dm-3 phosphate buffer solution (ph 5.0) and 0.02 mol dm-3 phosphate buffer solution (ph 7.0) at 25 and 40ºc, respectivel...

Low-level attacks often rely on guessing absolute or relative memory addresses. Layout randomization aims to thwart such attacks. In this paper, we study layout randomization in a setting in which arrays and functions can be stored in memory. Our results relate layout randomization to language-level protection mechanisms, namely to the use of abstract locations (rather than integer addresses). ...

This paper presents LEOPARD, a Logical Effort-based fanout OPtimizer for ARea and Delay, which relies on the availability of a (near) continuous size buffer library. Based on the concept of logical effort in VLSI circuits, the proposed algorithm attempts to minimize the total buffer area under the required time and input capacitance constraints by constructing the fanout tree topology and assig...

Due to the voluntary withdrawals and/or bans on the use of two polybrominated diphenyl ether (PBDE) commercial mixtures, an increasing number of alternate flame retardant chemicals are being introduced in commercial applications. To determine if these alternate BFRs are present in indoor environments, we analyzed dust samples collected from 19 homes in the greater Boston, MA area during 2006. U...
