The current developments of NIR-responsive CDs and their applications in bioimaging phototherapy are highlighted this review.

Recent study shows that the existing first order canonical timing model is not sufficient to represent dependency of gate delay on variation sources when processing and operational variations become more significant. Due nonlinearity mapping from gate/wire delay, distribution no longer Gaussian even if are normally distributed. A novel quadratic proposed capture non-linearity delays arrival times sources. Systematic methodology also developed evaluate correlation model. Based these, a...

Zirconia (ZrO2) ceramics have potential applications in the field of oral medicine owing to their desirable mechanical properties, biocompatibility, chemical stability, and aesthetic properties. To realize clinical applications, ZrO2(3Y)/Al2O3 bioceramics for all-ceramic dental implants were prepared using vat photopolymerization 3D printing technology, process optimization, microstructure, mechanics, tribology, biological properties studied. The results indicate that when sintering...

Process variations cause significant timing uncertainty and yield degradation in deep sub-micron technologies. A solution to counter is post-silicon clock tuning. Existing design approaches for post-silicon-tunable (PST) clock-tree synthesis usually insert a PST buffer each flip-flop or put buffers across an entire level of clock-tree. This can over-design long tuning time. In this paper, we propose at both internal leaf nodes use bottom-up algorithm reduce the number candidate locations. We...

The colors of commercial textiles via dyeing or printing procedures were stationary, and these processes affect ecological environment. existing thermochromic surface coating may involve poor permeability vapor/air inherent inelasticity, affected wearing comfort. Herein, we propose a facile scalable fabrication strategy to manufacture Joule heating-induced elastic wrapped yarn. spiral geometrical configuration yarn constituents draw ratio elastane filament (EF) are responsible for the...

Inconel 718/CuCrZr multi-metallic materials with good bonding were prepared by laser powder bed melting technology. The effects of process parameters on the interface characteristics multi-metal technology studied. Through optimization parameters, defect-free between 718 and CuCrZr transition zone is realized. In addition, microstructure characteristics, element distribution, microhardness tensile properties studied, behavior, formation mechanism discussed. experimental results show that...

An efficient and accurate statistical static timing analysis (SSTA) algorithm is reported in this paper, which features 1) a conditional linear approximation method of the MAX/MIN operator, 2) an extended canonical representation correlated variables, 3) variation pruning that facilitates intelligent tradeoff between simulation time accuracy result. A special design focus proposed on propagation correlation among variables through nonlinear circuit elements. The distinguishes itself from...

State of the art statistical timing analysis (STA) tools often yield less accurate results when variables become correlated due to global source variations and path reconvergence. To best our knowledge, no good solution is available for dealing both types correlations simultaneously. In this paper, we present a novel extended pseudo-canonical model retain evaluate correlation during with minimum computation cost. Also, an intelligent pruning method introduced enable trade-off runtime...

This paper examines onwards migration patterns and the factors that influence them in urban China. In contradiction to Ravenstein’s laws of step migration, we argue movement up hierarchy does not dominate Chinese context. Using 2017 China Migrants Dynamic Survey, model how past migratory experiences intersect with migrants’ demographic socio-economic characteristics explain stay-versus-move decision who moves as well down within China’s hierarchy. The general pattern domestic is a first...

With deep-sub-micron (DSM) technology, statistical timing analysis becomes increasingly crucial to characterize signal transmission over global interconnect wires. In this paper, a novel approach has been developed analyze the behavior of two important pipelined architectures for multiple clock-cycle interconnect, namely, flip-flop inserted wire and latch wire. We present analytical formula that is based on parameters obtained using Monte Carlo simulation. These results enable designer...

The current techniques for nondestructive quality evaluation of bumped solder joint connections in electronics packages are either incapable detecting cracks, or unsuitable inline inspection due to cost and throughput reasons. As an alternative, a novel system is being developed. projects short laser pulses onto specimen surface through optic fibers induce structural vibration. induced displacements then measured by Doppler vibrometer. A number digital signal processing algorithms, such as...

The detection of cracks in solder joints has been a challenge for the current nondestructive inspection techniques.
