Scaling test of fermion actions in the Schwinger model [PDF]

, 2005
We discuss the scaling behaviour of different fermion actions in dynamical simulations of the 2-dimensional massive Schwinger model. We have chosen Wilson, hypercube, twisted mass and overlap fermion actions.

Research on Vertical Bearing Characteristics of Single Pile in Complex Interactive Karst Area

Buildings
This study investigates the vertical bearing characteristics of single-pile foundations in complex karst areas, focusing on the influence of underlying cavities, eccentric cavities, and beaded cavities.

Study of Load Calculation Models for Anti-Sliding Short Piles Using Finite Difference Method

Applied Sciences, 2023
Anti-sliding short piles, a novel technique for slope stabilization, have been applied in engineering practices. Nonetheless, a mature structural calculation theory for these piles is still lacking.

Study on the Optimized Perception of Structural Behavior in Shield Tunneling by Fiber Grating Layouts

Buildings
Shield tunnels’ structural stability is challenged due to the fact that they are often built under rivers, lakes, and oceans. It is crucial to execute the structural deformation perception of the shield tunnel.

Morphological Evolution of Passive Soil Arch in Front of Horizontal Piles in Three Dimensions

Buildings, 2022
The anti-slide pile is a primary method of landslide control. The effect of the passive soil arch in front of the embedded section of piles has a significant effect on the anti-slide pile’s bearing capacity.

Analysis of Multilayered Ground Amplification Characteristics by Scaled-Down Model Tests

Applied Sciences, 2022
During an earthquake, seismic waves travel through different media through the source to reach the surface. It is very necessary to study the dynamic characteristics of soil between different layers during earthquake.

Cost Model-Driven Test Resource Partitioning for SoCs

, 2006
The increasing complexity of modern SoCs and quality expectations are making the cost of test represent an significant fraction of the manufacturing cost.

Testing Conditional Factor Models [PDF]

SSRN Electronic Journal, 2009
We develop a new methodology for estimating time-varying factor loadings and conditional alphas based on nonparametric techniques. We test whether long-run alphas, or averages of conditional alphas over the sample, are equal to zero and derive test statistics for the constancy of factor loadings. The tests can be performed for a single asset or jointly

The HIT Network for Children and Adolescents With CNS Tumors Facilitates Improvements of Diagnostic Assessments, Multimodal Treatments, Individual Counseling, and Research in Germany, Austria, and Switzerland

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The HIT network was established in 2000 to create a population‐based structure aiming to improve survival rates and reduce late effects for children with central nervous system (CNS) tumors by conducting comprehensive clinical trials.
