Inverse Gini indexed averaging: A multi-leveled ensemble approach for skin lesion classification using attention-integrated customized ResNet variants.

Objective: To improve the accuracy and explainability of skin lesion detection and classification, particularly for several types of skin cancers, through a novel approach based on the convolutional neural networks with attention-integrated customized ResNet variants (CRVs) and an optimized ensemble learning (EL) strategy.

Methods: Our approach utilizes all ResNet variants combined with three attention mechanisms: channel attention, soft attention, and squeeze-excitation attention. These attention-integrated ResNet variants are aggregated through a unique multi-level EL strategy.

Phase stability, electronic, mechanical, lattice distortion, and thermal properties of complex refractory-based high entropy alloys TiVCrZrNbMoHfTaW with varying elemental ratios.

This study examines the intricate area of refractory-based high entropy alloys (RHEAs), focusing on a series of complex compositions involving nine diverse refractory elements: Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, and W. We investigate the phase stability, bonding interactions, electronic structures, lattice distortions, mechanical, and thermal properties of six RHEAs with varying elemental ratios using VASP and OLCAO DFT calculations. Through comprehensive analysis, we investigate the impact of elemental variations on the electronic structure, interacting bond dynamics, lattice distortion, thermodynamic, mechanical, and thermal properties within these RHEAs, providing an insight into how these specific elemental variations in composition give rise to changes in the calculated properties in ways that would guide future experimental and computational efforts.

A single droplet dispensing system for high-throughput screening and reliable recovery of rare events.

Microfluidic droplet sorting has emerged as a powerful technique for a broad spectrum of biomedical applications ranging from single cell analysis to high-throughput drug screening, biomarker detection and tissue engineering. However, the controlled and reliable retrieval of selected droplets for further off-chip analysis and processing is a significant challenge in droplet sorting, particularly in high-throughput applications with low expected hit rates. In this study, we present a microfluidic platform capable of sorting and dispensing individual droplets with minimal loss rates.

Using Technique and Technology to Improve Safety and Outcomes in AIS: A Review of 12,795 Screws in Pediatric Spine Deformity.

Study Design: Retrospective Cohort Study.

Objective: This study aimed to compare outcomes in AIS patients that underwent PSF using either freehand with occasional fluoroscopic assistance (FOFA), computer assisted surgery/navigation (CAS), or technique and technology (T&T).

Summary Of Background Data: Pedicle screw insertion in scoliosis is challenging due to abnormal pedicle morphology.

The past, present and future of simulation-based medical education (SBME) in Pakistan: a short report.

Simulation-based education has been widely implemented in fields such as the aviation industry and the military. Its applications to the field of healthcare education have started to show significant promise globally over the last few decades. Medical education institutions in Pakistan have relied primarily on traditional forms of didactic lectures, apprenticeship models and small-group clinical sessions for clinical skills education in medical schools.
