This paper presents the design of a front-end circuit for monolithic active pixel sensors. The circuit operates with a sensor featuring a small, low-capacitance (< 2 fF) collection electrode and is ...integrated in the DPTS chip, a proof-of-principle prototype of 1.5 mm × 1.5 mm including a matrix of 32 × 32 pixels with a pitch of 15 μm. The chip is implemented in the 65 nm imaging technology from the Tower Partners Semiconductor Co. foundry and was developed in the framework of the EP-R&D program at CERN to explore this technology for particle detection. The front-end circuit has an area of 42 μm 2 and can operate with a power consumption as low as 12 nW. Measurements on the prototype relevant to the front-end will be shown to support its design.
Abstract
The National Center for Biotechnology Information (NCBI) provides a large suite of online resources for biological information and data, including the GenBank® nucleic acid sequence database ...and the PubMed database of citations and abstracts for published life science journals. The Entrez system provides search and retrieval operations for most of these data from 39 distinct databases. The E-utilities serve as the programming interface for the Entrez system. Augmenting many of the Web applications are custom implementations of the BLAST program optimized to search specialized data sets. New resources released in the past year include PubMed Data Management, RefSeq Functional Elements, genome data download, variation services API, Magic-BLAST, QuickBLASTp, and Identical Protein Groups. Resources that were updated in the past year include the genome data viewer, a human genome resources page, Gene, virus variation, OSIRIS, and PubChem. All of these resources can be accessed through the NCBI home page at www.ncbi.nlm.nih.gov.
Microinclusions of ore minerals were found and studied in grains of native gold for characterization of the mineralogy of placer gold of the South Urals. One hundred ten unrounded and poorly rounded ...grains with a size of 1–2 mm from eight placer zones were studied. Microinclusions of ore minerals were detected in six placers of the Miass zone. The list of minerals includes sulfides, arsenides, Cu-bearing Au, and PGEs. All microinclusions show links to certain deposits of ore gold and chromite occurrences. It is suggested that the northern flanges of the Talovsky and Nurali massifs containing gold placers with PGEs require a search for PGE mineralization.
The study was designed to assess clinical efficiency and safety of nebivolol in patients with cardiovascular problems and chronic obstructive pulmonary disease. It included 50 patients of whom 25 ...were given daily 5 and 25 mg of nebivolol and 80-100 mg of verapamil. Nebivolol was shown to significantly reduce arterial pressure, heart rate, and the number of ventricular extrasystoles. The drug was well tolerated by the patients and had no adverse effect on bronchial patiency.
Forty-five patients with coronary heart disease and various forms of ventricular arrhythmias (25 men and 20 women aged 42 to 73) were examined. The use of complex therapy with emoxipin and preductal ...in a combination with antiarrhythmic agents potentated the action of these preparations. The application of emoxipin resulted in a longer positive effect.
Antiarrhythmic therapy of patients with disturbed automatism of the sinus node and impaired atrioventricular conductance may be complicated by hemodynamically significant bradycardias and ...contraindications for implantation of a cardiac electrical stimulator This study aimed at estimating effect of antiarrhythmic therapy with allapinin on the function of sinus and atrioventricular nodes. It included 20 patients (mean age 37.5+-2.3 years) with disturbed cardiac rhythm and sinus node dysfunction treated with allapinin (37.5 - 50 mg/d per os). This therapy had well apparent antiarrhythmic effect manifest as improvement of supraventricular and ventricular ectopic activities in the absence of negative influence on the function of sinus and atrioventricular nodes.
We studied effect of the neoplastic process and surgical treatment on parameters of the oxidative system in patients with stomach cancer including serum and gastric tissue levels of malonic ...dialdehyde, lactic and pyruvic acids in stage I-IV malignancy before and after radical surgery. The development and generalization of the neoplastic process are associated with the activation of oxidative reactions leading to endotoxicosis. Specific anticarcinogenic treatments (including surgery) aggravate changes in the oxidative systems and further deteriorate quality of life and tolerance of the treatment.
The aim of the study was to examine effect of cardioversion (CV) on the subjective and objective status of patients with persistent atrial fibrillation (AF) receiving different therapy. The study ...included 4 groups of patients (n = 85). Group 1 (n = 30) were given standard treatment. In group 2 (n = 25), standard therapy was supplemented by i.v. injections of emoxipin (200 mg/day). Treatment of group 3 (n = 10) included mildronat (50 mg/day, i.v.), patients of group 4 (n = 20) were given riboxin (200 mg/day, i.v.). It was shown that the recovery of sinus rhythm improved the quality of life and parameters of cardiovascular function in all the treated patients.
