A novel chatter-resistant boring bar design with lattice structure and non-Newtonian fluid

Due to the low dynamic stiffness of long boring bars, chatter is a significant challenge for boring operations, resulting in poor surface finish and reduced tool life. Various passive chatter suppression techniques have been developed to enhance their dynamic performance, includi...

Pretreatment Body Composition Parameters and HALP Score in Relation to Pathological Complete Response in HER2-Positive Breast Cancer Receiving Neoadjuvant Systemic Therapy

Background/Objectives: Pathological complete response (pCR) is an important early endpoint in HER2-positive breast cancer treated with neoadjuvant therapy. Although tumor biology is a major determinant of response, the potential contribution of host-related factors such as body c...

Unilateral Approach for Bilateral Lumbar Disc Herniation: A Tissue-Preserving Technique

Abstract Minimally-invasive techniques are increasingly preferred for lumbar discectomy. To evaluate the feasibility and clinical outcomes of a tissue-preserving unilateral approach for managing bilateral lumbar disc herniation. We conducted a retrospective review of two patients...

Finite element analysis driven optimization of an electrodynamic levitation system with permanent magnet Halbach arrays

This study presents a finite element analysis (FEA)-driven optimization for the design of an electrodynamic levitation (EDL) system incorporating permanent magnet Halbach arrays (PM-HAs). The primary objective is to maximize the net force difference between lift ( F y ) and drag...

Split Versus Single Applications of Solid and Liquid Vermicompost: Impacts on Growth, Chlorophyll Content and Soil Characteristics of Tea (Camellia sinensis L.) Seedlings

Limited information is available on how vermicompost form, form-specific dose, and application schedule jointly affect tea seedling development. This 135-day humid outdoor nursery study evaluated solid and liquid vermicompost applied at two doses as either single or three split a...

Online sexual exploitation and grooming in inclusive settings: school response mechanisms and the first 24 h

The increasing integration of digital technologies into inclusive school settings may heighten the vulnerability of students with special educational needs to online child sexual exploitation and abuse (OCSEA) and online grooming. This study examines schools’ capacity to identify...

Hybrid deep learning for three-way classification of human-written, AI-generated, and AI-rephrased text

Abstract The rapid proliferation of large language models (LLMs) has made it increasingly difficult to distinguish AI-generated and AI-rephrased text from authentic human writing, posing serious risks to academic integrity, journalism, and e-commerce credibility. This paper prese...

Transport Productivity, Hydrogen Innovation, and Environmental Sustainability: Evidence From High‐Income Economies in Achieving SDG Targets

ABSTRACT Environmental sustainability has become a major policy challenge for high‐income economies, particularly as expanding transport systems increase energy demand and ecological pressure. This raises concerns about the compatibility of economic efficiency with the Sustainabl...

Influence of regional artificial cavity layouts on flow boiling in micro heat sinks with stepwise-decreasing pin-fin heights

Novel heat sink configurations and associated flow boiling physics were examined. Specifically, the influence of regional artificial cavity layouts on flow boiling in micro heat sinks with stepwise decreasing pin-fin heights was investigated. Four heat sinks with stepwise decreas...

Larval Co-occurrence and Habitat Occupancy Patterns of Aedes albopictus, Aedes aegypti, and Culex pipiens in Urban Artificial Habitats of Northeastern Türkiye

Aedes albopictus and Aedes aegypti are invasive container-breeding mosquitoes whose expanding distributions increasingly overlap with resident mosquito species in human-modified environments. In northeastern Türkiye, urban artificial habitats provide a field system in which invas...

Effects of suboccipital or thoracolumbar self-myofascial release added to hamstring stretching on flexibility, spinal mobility, and balance in recreational athletes with hamstring tightness: a three-arm randomized controlled trial

Hamstring stretching and self-myofascial release are commonly used in sports physiotherapy, exercise preparation, and rehabilitation to acutely improve range of motion. However, whether self-myofascial release applied to anatomically remote regions provides additional benefits re...
