This paper discusses a statistical effect of performance optimization to uncertainty in circuit delay. Performance optimization has an effect of balancing the delay of each path in a circuit, i.e. the delay of long paths are shortened and the delay of short paths are lengthened. In these path-balanced circuits, the uncertainty in circuit delay, which are caused by delay calculation error, manuf...

The traditional method of hydrology and water conservancy calculation is based on the assumption natural runoff, while applicability has weakened in urbanization-affected river basins. paper carried out research hydrological model flood control middle lower reaches Chuhe River under background urbanization. On basis analysis characteristics basins, framework constructed, which includes five mod...

According to our present understanding many J/c production processes proceed through a colored cc̄ state followed by the emission of soft particles in the quarkonium rest frame. The kinematic effect of soft particle emission is usually a higher-order effect in the non-relativistic expansion, but becomes important near the kinematic end point of quarkonium energy ~momentum! distributions. In an i...

One-sample and two-sample t-tests are commonly used in analyzing data from clinical trials in comparing mean responses from two drug products. During the planning stage of a clinical study, a crucial step is the sample size calculation, i.e., the determination of the number of subjects (patients) needed to achieve a desired power (e.g., 80%) for detecting a clinically meaningful difference in t...

Accurate near surface ozone concentration calculation with high spatial resolution data is very important to solve the problem of serious pollution and health impact assessment. However, existing remotely sensed products cannot meet requirements monitoring. In this study, O 3 (at 30 km resolution) was extracted from daily TROPOMI profile products. Meanwhile, study improved downscaling algorithm...

We discuss new results in QCD obtained with string-based methods. These methods were originally derived from superstring theory and are significantly more efficient than conventional Feynman rules. This technology was a key ingredient in the first calculation of the one-loop five-gluon amplitude. We also present a conjecture for a particular one-loop helicity amplitude with an arbitrary number ...

Simulation of gate circuits is an efficient method of detecting hazards and oscillations that may occur in the presence of gate and wire delays. Ternary simulation, introduced by Eichelberger in 1965, consists of two algorithms, called A and B, and its results are well understood. Ternary simulation has been generalized by Brzozowski and Ésik in 2003 to an infinite algebra C and finite algebras...
