Evolutionary Trails of Plant Group II Pyridoxal Phosphate-Dependent Decarboxylase Genes
Type II pyridoxal phosphate-dependent decarboxylase (PLP_deC) enzymes play important metabolic roles during nitrogen metabolism. Recent evolutionary profiling of these genes revealed a sharp expansion of histidine decarboxylase genes in the members of Solanaceae family. In spite of the high…

Contractualist reasoning, HIV cure clinical trials, and the moral (ir)relevance of the risk/benefit ratio
Institutional review boards (IRB) normally require of a morally defensible clinical trial that any trial participant will benefit from the inquiry, or at least not be exposed to a significant risk of having their prospects worsened by participating. Stage 1 HIV cure trials tend not to meet this…

Magnetic Field Sensing Using Tapered Small-Core Optical Fibre Surrounded by Different Concentrations of Magnetic Fluid
In this paper, a high-sensitivity magnetic field sensor based on a single-mode–tapered small-core–single-mode (STSCS) optical fibre structure is investigated. The tapered small-core section of STSCS is surrounded by magnetic fluid (MF) containing ferromagnetic particles (FMPs) of different…

Metabolic regulation of Escherichia coli and its gdhA, glnL, gltB, D mutants under different carbon and nitrogen limitations in the continuous culture
Abstract Background It is quite important to understand how the central metabolism is regulated under nitrogen (N)- limitation as well as carbon (C)- limitation. In particular, the effect of C/N ratio on the metabolism is of practical interest for the heterologous protein production, PHB…

Stimulation of extracellular invertase production from spent yeast when sugarcane pressmud used as substrate through solid state fermentation
Efforts were made to utilize the waste/by-product of two agro-process industries namely pressmud from sugar processing industries and spent yeast from distilleries manufacturing ethanol from cane molasses, for the production of microbial invertase. Our experimentation indicated that these two…

FQI: feature‐based reduced‐reference image quality assessment method for screen content images
In this study, a reduced‐reference image‐quality‐assessment (IQA) method for screen content images, named as feature‐quality‐index (FQI) is proposed. The proposed method is based on the fact that the human visual system is more sensitive towards change in features than intensity or structure…
