A small-scale laboratory apparatus was built to study liquid friction modifier (LFM) behavior in a top-of-rail application. field experiment also carried out complement the findings. KELTRACK® (a water-based LFM) used as test fluid. Laser-induced fluorescence served measure LFM thickness left on track after passage of wheel. The lab experiments show that cannot withstand high wheel-rail contact...

Modern missile seekers invariably employ monopulse radar with phase locked loop (PLL) as a frequency (angle) tracking subsystem in the receiver. The frequency locking and/or unlocking of these receivers can be achieved either by introducing imperfections in the monopulse design or using multiple repeater sources. In the present paper, the break-lock of PLL synthesizer in the monopulse radar rec...

The present study aimed to investigate the role of Bruton's tyrosine kinase (BTK) in the pathogenesis of lung injury induced by trauma‑hemorrhagic shock (THS), and to examine the pulmonary protective effects of BTK inhibition. Male Sprague‑Dawley rats were divided into four groups (n=12/group): i) A Sham group, which received surgery without induced trauma; ii) a THS‑induced injury group; iii) ...

Abstract 3D microscopy is a useful tool to visualize the detailed structures and mechanisms of biomedical specimens. In particular, biophysical phenomena such as neural activity require fast volumetric imaging because fluorescence signals degrade quickly. A light-field microscope (LFM) has recently attracted attention high-speed technique by recording information in single-snapshot. This review...

The Local Fitness Method (LFM) and Speaker-Listener Label Propagation (SLPA) algorithms are widely used to detect overlapping communities in complex networks. main problem with these two is that they extremely sensitive the setting of hyperparameters. Previous methods set hyperparameters LFM or SLPA based on either empirical values random choices, resulting a large amount computation for adjust...

Epidermal growth factor receptor (EGF-R) tyrosine kinase is known to be overexpressed in several malignancies and is an important target for anticancer drug design. We constructed a homology model to represent the structure of EGF-R and propose that this model can be used to design potent inhibitors of EGF-R. We used our EGF-R model and a docking procedure to rationally design compounds predict...
