A positively charged chiral stationary phase (CSP) was prepared by chemically immobilizing cellulose 3,5-dimethylphenylcarbamate onto methacryloyldiethylenetriaminopropylated silica (MCDEAPS) via a radical copolymerization reaction. The prepared CSP was evaluated for enantiomer separation in nonaqueous capillary electrochromatography (CEC). Electroosmotic flow (EOF) generated on the prepared CS...

Cooling intense high-energy hadron beams is a major challenge in modern accelerator physics. Synchrotron radiation is too feeble and two common methods – stochastic and electron cooling – are not efficient in providing significant cooling for high energy, high intensity proton colliders. In this paper we discuss a practical scheme of Coherent Electron Cooling (CeC), which promises short cooling...

Combinational equivalence checking (CEC) is a mainstream application in Electronic Design Automation used to determine the equivalence between two combinational netlists. Tools performing CEC are widely deployed in the design flow to determine the correctness of synthesis transformations and optimizations. One of the main limitations of these tools is their scalability, as industrial scale desi...

In this paper a novel capillary electrophoresis chip (CEC) is presented with integrated platinum electrodes and simplified conductivity detector. CEC is fabricated by the method of mechanical modification with probe on organic glass. Capillary electrophoresis chip can rapidly completed ion separation by simulation of concentration distribution and zonebroadening. Detection circuit is simple whi...

T he past several years have seen a significant resurgence of interest in cap i l l a ry electro ch ro m at ography(CEC), a hybrid technique that combines the high efficiency owing to the flow characteristics related to electroosmosis with the selectivity of high performance liquid chromatography(HPLC). In CEC, separations are generally carried out using fused silica capillaries packed with HPL...

CEC is a high performance electrodriving liquid phase separation technique. It does not need complex and sophisticated high pressure instrumentation for nanoflow driving. This is attractive for parallel multicolumn analysis. To this end, high throughput methods for column preparation are needed to support the use of multiple columns. In this study, we directly used CEC mobile phase solution as ...

Studies of advanced space very long baseline interferometry (SVLBI) missions envision data rates as high as 8 Gb/s, but to accomplish such high-rate data transfer from the spacecraft to ground using digital downlinks requires high effective isotropic radiated power (EIRP), as well as complex and substantially advanced modulation and receiving techniques. For these reasons, analog signal transfe...

The mechanism of immune tolerance is to be further understood. The present study aims to investigate the role of the Cardiac endothelial cell (CEC)-derived exosomes in the induction of regulatory B cells. In this study, CECs were isolated from the mouse heart. Exosomes were purified from the culture supernatant of the primary endothelial cells. The suppressor functions of the regulatory B cells...

Deception is a core component of human interaction and reasoning, and despite its negative connotation, it can be used in positive ways. We present our formalization behind strategic deception, one such potentially positive form of deception. We use the Cognitive Event Calculus (CEC) to model strategic deception, building on prior formalizations. First, we provide a brief overview of deception’...

The aim of this study was to compare the outcomes after phacotrabeculectomy at 1 or 2 sites in the small adult eyes with concomitant cataract and glaucoma.Patients who had 1-site (n = 26) or 2-site (n = 14) phacotrabeculectomy over a 4-year period at an eye surgery center were included. Eighteen eyes of 18 patients with glaucoma using any 1 prostaglandin analogue (latanoprost, travoprost, or bi...
