We developed a reconfigurable nuclear instrument system (RNIS) that could satisfy the requirements of diverse nuclear and particle physics experiments, and the inertial confinement fusion diagnostic. Benefiting from the reconfigurable hardware structure and digital pulse processing technology RNIS shakes off the restrictions of cumbersome crates and miscellaneous modules. It retains all the advantages of conventional nuclear instruments and is more flexible and portable. RNIS is primarily composed of a field programmable hardware board and relevant t)C software. Separate analog channels are designed to provide different functions, such as am- plifiers, ADC, fast discriminators and Schmitt discriminators for diverse experimental purposes. The high-perfornmnce field programnmble gate array could complete high-precision time interval measurement, histogram accumulation, counting, and coincidence anticoincidence measurement. To illustrate tile prospects of RNIS, a series of applications to the experiments are described in this paper. The first, for which RNIS was originally developed, involves nuclear energy spectrum mea- surement with a scintillation detector and photonmltiplier. The second experiment applies RNIS to a G-M tube counting experiment, and in tile third, it is applied to a quantum comnnmication experiment tllrough reconfiguration. 展开更多

Hydrogel-based injectable tissue prostheses connect and modulate the responses of surrounding cells and tissues after a tissue defect by reconstructing a bio-instructive microenvironment.This reconstruction is essential for maintaining homeostasis,which is crucial for tissue growth,repair,regeneration,and rehabilitation.Hydrogel-induced rehabilitation has received much attention in tissue function reconstruction from fundamental research and practical applications in recent years.In particular,bioactive hydrogels with special(bio)physicochemical characteristics,such as conductivity,appropriate diffusibility,biomimetic structure,bio-adapted biodegradation,and biocompatibility,are becoming increasingly desirable biomaterials for nerve and muscle rehabilitation. 展开更多

Functional recovery from central nervous system(CNS)trauma depends not only on axon regeneration or compensatory sprouting of uninjured fibers but also on the ability of newly grown axons to establish functional synapses with appropriate targets.Although several studies have successfully promoted long-distance axonal regeneration in distinct CNS injury models,none of them have resulted in a viable therapeutic approach for patient recovery.A possible reason may be the lack of new synaptogenesis for reestablishing the circuitry lost after injury.Herein,we discuss how our understanding of the mechanisms that instruct synapse formation in the injured nervous system may contribute to the design of new strategies to promote functional restoration in traumatic CNS disorders. 展开更多

The band alignment between silicon and high-k dielectrics,which is a key factor in device operation and reliability,still suffers from uncontrolled fluctuations and ambiguous understanding.In this study,by conducting atomic-level ab initio calculations on realistic Si/SiO_(2)/HfO_(2)stacks,we reveal the physical origin of band alignment fluctuations,i.e.,the oxygen density-dependent interface and surface dipoles,and demonstrate that band offsets can be tuned without introducing other materials.This is instructive for reducing the gate tunneling current,alleviating device-to-device variation,and tuning the threshold voltage.Additionally,this study indicates that significant attention should be focused on model construction in emerging atomistic studies on semiconductor devices. 展开更多
