Spermatogenesis in many species including Drosophila melanogaster is accompanied by major reorganisation of chromatin in post-meiotic stages, involving a nearly genome-wide displacement of histones by protamines, Mst77F and Protamine-like 99C.A proposed prerequisite for the histone-to-protamine transition is massive histone H4 hyper-acetylation pri
Abstract Thermochromic perovskite smart windows (TPWs) are a cutting-edge energy-efficient window technology.However, like most perovskite-based devices, humidity-related degradation limits their widespread application.Herein, inspired by the structure of medical masks, a unique triple-layer thermochromic perovskite window (MTPW) that enable suffic
Phraseological units that embrace artistry, emotional value, expressiveness in their meaning, can not fully disclose the situation, therefore, between the components of such phraseological units there are free words, word combinations from different parts of speech.This method, contributed to the emergence of additional meanings in phraseological u
The association between long standing extensive ulcerative colitis and the increased risk for developing colorectal cancer suggests ESSENTIAL EYE CARE that surveillance by frequent and regular colonoscopies may provide a means for reducing cancer-related morbidity and mortality.A crude calculation suggests that such a surveillance program would als
An improved road impedance function in conformity with Chinese city road traffic is designed for calculating the actual transportation time based on real-time traffic information and the complex road environment in the city.The objective function minimizes the total distribution cost, including fixed cost, transportation cost, damage cost, energy c
