Modelling of Skin Effect in On-Chip VLSI RLC Global Interconnect
Abstract: This paper addresses one of the aspects of the high frequency effects, namely the skin effect. The basicproblem with skin effect is that it attenuates the high frequency components of a signal more than that ofthe low frequency components. Due to the increase in operating frequency and die sizes, RC models arebecoming insufficient for analysis of global VLSI interconnects. Accurate noise modelling for RLC lines isthus critical for timing and …

An Overview of Haemorrhoids (Bawaseer) with Surgical Interventions from Ancient to Modern Era
Abstract: The word “haemorrhoid” is derived from the Greek “haema”= blood, and “rhoos”= flowing, and was originally used by Hippocrates to describe the flow of blood from the veins of the anus. Commonly, in society it is known as piles, the word pile is derived from Latin, meaning a ball or a mass. In Unani literature, hemorrhoids are known as “Bawaseer”. It is the plural of baasoor, which means wart or …

Stature Estimation for Human Identification by PA Cephalometric Mandibular Parameters
Abstract: Background: Biological profile assessment for establishing identity can be done by using cephalometric radiographs. As often the skull and mandible are the only remains available, they can be used to get estimate of stature which is one of the important parameters for personal identification. This study was aimed at deriving stature from Posterio-anterior (PA) cephalometric mandibular parameters in adult Chhattisgarh population. Method: About 50 males and 50 females in the …

Menstrual Blood Banking: A Future Need and Scope
Abstract: Stem cells abundant in menstrual blood possess the capacity to develop and differentiate into various cell types. The regenerative capacity of these stem cells derived from menstrual blood is comparable to that observed in stem cells present in umbilical cord blood and bone marrow. Every healthy woman experiences menstruation on average once every 28 to 30 days from the time of menstruation till menopausal. Menstrual blood banking involves storing menstrual …

Relationship Between Conceptual Load and Output in Children with Learning Disability
Abstract: Discourse analysis is a term given to a cluster of approaches intended in measuring the output with reference to the output measured on verbal, written or sign language. The output can be measured in terms of C units, T units etc. The output derived would be directly related to the conceptual output. The conceptual unit also reflects the relationship shared by the conceptual load and verbal output. Discourse analysis is …

Hemorrhoids (Bawaseer) in Unani System of Medicine: A Review
Abstract: Hemorrhoids are one of the most common anorectal disorders encountered in the general population as well as in clinical practice. The term “Hemorrhoid” was most likely first used by Hippocrates (Buqrat) to explain the bleeding from the veins of the anus. It is derived from two Greek words “haima" means blood, “rhoos" means flowing. Bawaseer are dilated veins occurring in relation to the anal canal. In normal population the disease …

Reliability-Aware Mathematical Model for Radiation-Hardened Satellite Communication Systems
Abstract: Satellite communication systems operate in radiation environments in which total ionizing dose (TID), displacement damage, and single-event effects (SEE) can progressively degrade electronic, optoelectronic, and communication components and can ultimately reduce link availability and mission reliability. This paper develops a Reliability-Aware Radiation-Hardened Satellite Communication Model (R-RHSCM) that mathematically couples the orbital radiation environment, accumulated radiation dose, component degradation, communication-link performance, single-event failure probability, redundancy, thermal effects, and adaptive mitigation.

Mathematical Analysis and Stability Analysis of Coupled Orbital–Attitude Dynamics for Autonomous Spacecraft under Perturbative Forces
Abstract: Autonomous spacecraft operating in Earth orbit are subjected to coupled translational and rotational dynamics influenced by gravitational and environmental perturbations. Accurate mathematical characterization of these interactions is essential for trajectory prediction, attitude stabilization, autonomous navigation, and mission reliability. This study develops a nonlinear mathematical framework for coupled orbital–attitude dynamics of an autonomous spacecraft under perturbative forces. The translational dynamics are formulated using the two-body gravitational model augmented by the second …

Comparative Evaluation of Pedigree-Based and Genomic BLUP Models for Wheat Grain Yield Prediction
Abstract: Before genome-wide molecular markers became affordable, plant and animal breeding relied on pedigree-based prediction (P-BLUP), using the expected additive relationship matrix (A) derived from recorded ancestry. Genomic selection replaced or augmented this with a marker-derived genomic relationship matrix (G; GBLUP), and single-step methods combining A and G are now standard when only a subset of a breeding population is genotyped. It is less clear whether pedigree information retains any predictive …
