A method based on the usage of efˇciency proˇle is proposed to estimate the hit efˇciency of drift chambers with a large number of channels. The performance of the method under real conditions of the detector operation has been tested analysing the experimental data from the HERA-B drift chambers.

Purpose The aim of this integrative review was to describe communication experiences and needs among the critically ill with an artificial airway evaluate relevant intervention studies. Methods Using method employed by Whittemore Knafl (2005), we searched for papers on PubMed, CINAHL, Web Science published from January 1, 2015 September 25, 2020. A total 26 (11 descriptive studies, 15 experimen...

In the field of automatic target recognition(ATR) with synthetic aperture radar(SAR) imagery, it is usually impractical to obtain SAR images covering a full range aspect views. When database consists limited angular diversity, can lead performance degradation SAR-ATR system. To address this problem, paper proposes deep learning-based method where channel attention modules(CAMs) are inserted con...

In this paper, we calculate the transverse momentum diffusion coefficient κT of heavy quark and gluon penetration length in the deconfinement phase of Sakai-Sugimoto model, which is known as a holographic dual of large Nc QCD. We find that for the heavy quark moving through the thermal plasma with a constant velocity v < 1, the transverse momentum diffusion coefficient κT ∝ λγ 1 3 T /Td, and th...
