Solar Panel Efficiency Calculation using Incremental Conductance Algorithm

open access: yesInternational Journal of Recent Technology and Engineering (IJRTE), 2019
Solar energy is a vital renewable source of energy in India. To extract and utilize this renewable source of energy photovoltaic solar panels are used. To gather the maximum amount of energy a good efficiency solar panels are used. The maximum efficiency is achieved when the maximum irradiation from the sun is received by the earth. The irradiation and

Innate Immune Reprogramming Mediated by Endogenous Retroelement Dysregulation Drives Multiple Sclerosis Progression

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Epigenetic reprogramming in hematopoietic stem and progenitor cells (HSPCs) and downstream myeloid cells, mediated by H3.3 downregulation and endogenous retroelement (ERE) overexpression, contributes to the progression of multiple sclerosis (MS). ABSTRACT Background Skewed myelopoiesis in the bone marrow has been identified as a key driver of multiple ...

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.
