In order to improve the high-performance liquid chromatographic separation of alpha-amino acids derivatized with the fluorogenic reagent 4-fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F) on commercially available chiral stationary phases (CSPs) such as SUMICHIRAL OA-2500(S) (CSP 1) and OA-4700 (CSP 3), the preparation of two new CSPs (CSP 2 and CSP 4) having 11-aminoundecanoic acid between the amin...

Nowadays, One-Dimensional Cutting Stock Problem (1D-CSP) is used in many industrial processes and re-cently has been considered as one of the most important research topic. In this paper, a metaheuristic algo-rithm based on the Simulated Annealing (SA) method is represented to minimize the trim loss and also to fo-cus the trim loss on the minimum number of large objects. In this method, the 1D-...

Background and study aims  Despite widespread use of cold snare polypectomy (CSP), the R0 resection rate is not well documented. We perform extended CSP, resecting polyps with a > 1 mm circumferential margin. The aim of this study is to compare the R0 resection rate of extended CSP with conventional CSP and to assess safety. Patients and methods  From April 2014 to September 2016, 712 non-ped...

Traditionally, the various semantics of the process algebra Csp are formulated in denotational style. For many Csp models, e.g., the traces model, equivalent semantics have been given in operational style. A Csp semantics in axiomatic style, however, has been considered problematic in the literature. In this paper we present a sound and complete axiomatic semantics for Csp with unbounded nondet...

Background Chronic scrotal pain (CSP) may be debilitating in men presenting for treatment for CSP, but we have little information on the frequency and severity of CSP in the men who do not seek care for the CSP. Our objective was to identify the frequency and characteristics of CSP in a population of men presenting for reasons other than CSP to a urology clinic. Methods Men presenting to a ur...
