Can routine chest CT with artificial intelligence tool be used for opportunistically osteoporosis screening? A preliminary study
Abstract Introduction: Patients with pulmonary diseases face an elevated risk of osteoporosis. Conventional diagnosis relies on quantitative computed tomography (QCT), which delivers a high radiation dose and requires a dedicated scan. Whether conventional chest CT can be used for osteoporosis screening remains uncertain. Methods: A deep learning system was used to measure bone mineral density (BMD) in routine chest CT scans for osteoporosis screening, with QCT as the reference standard.
Urban climate resilience varies across space and time under climate hazard pressure in the Yangtze river delta urban agglomeration
Abstract Under intensifying climate change and rapid urbanization, urban agglomerations are increasingly exposed to climate hazards and socioeconomic pressures, making it important to understand whether improvements in adaptive capacity are sufficient to sustain urban resilience.
Drug Delivery-Enabled Antibiofilm Therapeutics from Traditional Chinese Medicine-Derived Bioactives: Recent Advances and Future Perspectives Click to copy article link Article link copied!
Abstract Click to copy section linkSection link copied! Biofilm-associated infections remain difficult to treat because the extracellular polymeric substance matrix, charge-selective transport, microenvironmental gradients, and persister formation together limit effective drug exposure and reduce the antimicrobial efficacy.
Barrier function-based variable-gain sliding mode control for aerospace electric fuel pumps
Abstract This paper presents a variable-gain sliding mode control (VGSMC) strategy based on a continuous barrier function to enhance the dynamic performance and disturbance rejection of aerospace electric fuel pumps. The approach integrates the robustness of conventional sliding mode control with adaptive gain tuning to reduce chattering while ensuring fast convergence. A comprehensive model of a surface-mounted permanent magnet synchronous motor (PMSM) and a nonlinear gear pump is developed.
Integrin inhibition facilitates fibrocartilaginous transformation in connective tissue in osteoarthritis
Abstract Osteoarthritis (OA) is a disabling condition with pathological remodeling of different joints, resulting in impaired function of the whole musculoskeletal system in vertebrates. Fibrocartilage has poor self-repair capacity after OA, leading to restricted treatment strategies and unsatisfying clinical efficacy.
Accumulation and Elimination: A Hard Decision-Based Multi-User Interference Cancellation Method in Satellite Communication System
1. Introduction With the rapid advancement of aerospace technology, satellite communication networks have garnered escalating attention from myriad industries. Among them, the Earth Medium Orbit Satellite (MEO) communication system has found extensive utilization across numerous countries and systems. Prominent examples include the BeiDou-3 short message communication system and the Global Positioning System (GPS) communication system, which has seen continuous development over the years.

Feasibility Analysis of Autonomous Orbit Determination and Gravity-Field Recovery around Asteroids Using Inter-Satellite Range Data
Abstract : Autonomous navigation and orbit determination are key problems of asteroid exploration missions. Inter-satellite range link is a type of measurement widely used in the orbit determination of Earth satellites, but not so widely used in missions around small bodies.
Regulatory role of human fibrocartilage stem cells in condyle osteochondroma
3.4 PI3K/AKT signalling pathway contributes to the development of CO by regulating apoptosis It was evident that there are significant expression differences of hub genes in PI3K/AKT signalling in the CO group. We therefore investigated protein expression in CO tissue by immunohistochemical analysis and scored the staining intensity. As shown in Figure 5A,B, strong AKT, FGFR2, BCL2, and BCL2-like protein 11 (BIM) staining was more frequent in CO tissue than in the normal condyle.
