It has been supposed that the interplay of elasticity and activity plays a key role in triggering non-equilibrium behaviors biological systems. However, experimental model system is missing to investigate spatiotemporally dynamical phenomena. Here, an active chain, where eccentric-disks are linked by spring, designed study activity, elasticity, friction. Individual chain exhibits longitudinal transverse motions; however, it starts self-rotate when pinning one end self-beat clamping end. In...
Abstract Background Multiple cell death modalities are implicated in sepsis pathobiology. However, the clinical relevance of NINJ1, a key mediator plasma membrane rupture during lytic death, progression and outcomes has remained poorly explored. Methods Circulating NINJ1 levels were measured 116 septic ICU patients, 16 non-septic controls, healthy controls. Comparative analysis serum across these groups was performed. Correlations between disease severity scores (SOFA, APACHE II) as well...
Thin Film Growth In article number 2404829, Wanyu Ding, Zixi Wang, and co-workers established a three-layer NiCr/NiSi thin-film thermocouple temperature measurement system in TiO2 film growth processes, to measure the gradient from surface substrate. The of substrate was about 132.05 °C, while difference between could reach 144.71 °C.
Objective: Previous studies suggest that the combination of robot-assisted training with other concurrent tasks may promote functional recovery and improvement better than single task. It is well-established rehabilitation effective. This study aims to characterize neural mechanisms inter-regional connectivity changes associated parallel interactive tasks. Methods: Twenty-five healthy young adults (12 females 13 males) participated in three number-related cognitive-motor categorized by...
Abstract Quantum dots (QDs) are semiconductor nanocrystals with superior quantum efficiency, narrow emission linewidths, and tunable bandgaps, making them valuable in optoelectronics. However, their commercialization is hindered by instability under stress environmental concerns related to heavy metal leaching. To address these issues, advanced encapsulation strategies, particularly using inorganic glass matrices (silicate, phosphate, borate), crucial. This review examines the...
