Crystal Defects and Their Characterization in Modern Materials Science
Abstract: The physical and chemical properties of crystalline solids are fundamentally dictated by deviations from structural perfection, known as crystal defects. From the point-scale vacancies that drive diffusion to the planar boundaries that determine mechanical strength, defects serve as the primary "tuning knobs" in material design. This review provides a comprehensive examination of point, line, and planar defects, exploring their formation energetics and their role in plastic deformation via crystallographic slip. …

Mandible reconstruction following resection of gingival squamous cell carcinoma with peroneal artery perforator based fibular osteocutaneous free flap
Abstract: Reconstructing soft tissue defect resulting from resection of malignant tumor in face is crucial in esthetic and functional point of view. To address this condition, various surgical flaps are used, including the free vascularized osteocutaneous flap. In this case, we used a free fibular osteocutaneous flap to reconstruct both the bone (osseous) and soft tissue (mucosal) defects. These defects were caused by the removal (resection) of a lesion in a …

Management of Kosthasakhashrita Kamala W.S.R. to Hepatocellular Jaundice – A Case Study
Abstract: Kosthasakhāśrit Kamala is a well-recognized clinical entity in Ayurveda and is widely correlated with modern hepatocellular jaundice. The condition arises primarily due to the vitiation of Pitta dosha within the Kostha (gastrointestinal tract), which subsequently spreads to the Sakha (peripheral tissues). Classical texts describe hallmark features such as Haridra Netra (yellowish discoloration of the eyes), yellowish hue of twak and nakha, pitta varṇa of mutra and sakrit (yellow urine and …

Reconstruction of broad soft tissue defect around knee with combined perforator flaps
Abstract: Perforator flaps have been commonly used in reconstruction of soft tissue defects nowadays; however, it is very important to apply them properly according to the characteristics of recipient site. Since there is no universal flap appropriate to various types of defects, there have been a number of research to apply appropriate perforator flaps suitable to recipient sites. Recently, achievements have been made by applying chimeric flaps based on perforators from …

Inverse Model for Predicting Thermal Abnormality of the Transient Process Triggered by Defective Electronics Element
Abstract: The paper presents a model for predicting thermal abnormalities in Printed Circuit Boards (PCBs) by approximating the thermal process of electric elements with heating from point sources. Circuit board heat sources are defined as point and non-point. The point heat source is a small electronic heating element that can be approximated as having originated from one point on the circuit board. A non-point source is one with heat distributed over …

Quantum-Fuzzy Tensor Operators and Uncertainty-Band Bifurcation for Symmetry-Preserving State Discrimination
Abstract: A tensor-operator framework is developed for fuzzy conjunction, fuzzy disjunction, and symmetry-preserving state discrimination in multi-qubit quantum systems. In this formulation, fuzzy membership and non-membership degrees are represented through expectations of effect operators acting on density matrices, providing a natural bridge between fuzzy logic and quantum measurement theory. Conjunction and disjunction operations are extended to the quantum domain via tensorised channels, constructed using projective measurements and unitary transformations, enabling logical …
