A prototype programmable bunch-by-bunch signal acquisition and processing channel with multiple applications in storage rings has been developed at SLAC. The processing channel supports up to 5120 bunches with bunch spac-ings as close as 1.9 ns. The prototype has been tested and operated in five storage rings: SPEAR-3, DA¨NE, PEP-II, KEKB, and ATF damping ring. The testing included such applica...

in this study an ultra-broad band, low-power, and high-gain cmos distributed amplifier (cmos-da) utilizing a new gain-cell based on the inductively peaking cascaded structure is presented. it is created bycascading of inductively coupled common-source (cs) stage and regulated cascode configuration (rgc).the proposed three-stage da is simulated in 0.13 μm cmos process. it achieves flat and high ...

Based on the fluorescence resonance energy transfer (FRET) and fluorescence anisotropy (FA), the present study reported proof-of-principle for a highly sensitive and rapid detection technique that can be precisely utilized for investigating the self-assembly of polydeoxyadenylic acid (poly(dA)) and β-glucan, and the interactions of the poly(dA)-β-glucan complex on the surface of graphene oxide ...

Background: Intestinal atresia is a life-threatening problem requiring early active intervention. The aim of the study was to compare management outcomes between Duodenal-Atresia (DA) and Jejunoileal-Atresias (JIA). The secondary objective was to analyse tapering enteroplasty versus end-to-end anastomosis in JIA. Materials and Methods: Retrospective descriptive analysis of patients operated be...

Authentic soybean β-amylase preparation, purified to homogeneity as judged by SDS-PAGE by using an affinity purification step, was composed of four pI-differing isoforms. By chromatofocusing, these isoforms were separated into three fractions, designated as fractions 1-3 in the order of elution. Fraction 1 contained two isoforms having the same molecular mass (55,989 Da), as measured by mass sp...

Jump Markov linear systems are linear systems whose parameters evolve with time according to a finite-state Markov chain. Given a set of observations, our aim is to estimate the states of the finite-state Markov chain and the continuous (in space) states of the linear system. The computational cost in computing conditional mean or maximum a posteriori (MAP) state estimates of the Markov chain o...
