2025 U.S. Geological Survey National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands: Overview of Model and Hazard Results

Earthquake Spectra, Volume 42, Issue 2, May 2026.
The U.S. Geological Survey recently updated the National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The first version of the PRVI NSHM was released in 2003, and therefore this 2025 update includes over 20 years of new geologic, geophysical, and engineering data, methods, and models.

Numerical Analysis Method of Shear Properties of Infilled Joints under Constant Normal Stiffness Condition

Advances in Civil Engineering, Volume 2018, Issue 1, 2018., 2018
The direct shear test is implemented in this paper for infilled joints under constant normal stiffness (CNS) condition with the finite difference software FLAC3D. The CNS condition was performed based on a servoprogram developed by FISH language. The effects of initial normal stress, undulating angle, and infilled ratio on the shear failure mode of ...

Various Diffraction Patterns of Steel Bead Through Direct/Indirect Collision With Light: Evidence for Particle–Wave Mechanism of Quantum

IET Optoelectronics, Volume 20, Issue 1, January/December 2026.
When the light is incident on a steel bead, diffraction patterns in forms of concentric circle, dots, and sawteeth are observed on the steel bead due to the sequential difference in the sphere of influence near the matter. ABSTRACT Based on Young's double‐slit experiment, the diffraction of light has been recognised as an exclusive property of the wave

Influence of electron and ion diamagnetic drifts on kink modes in low-resistivity tokamak plasma

Nuclear Fusion
In the present paper, we numerically investigate the influence of electron and ion diamagnetic drifts on the nonlinear evolution of kink modes in low-resistivity plasma through the updated CLT code based on bi-fluid model.

The Role of Carbon Content on the Microstructure of Rapidly Solidified Fe–Cr–Ni Duplex Steels

steel research international, Volume 96, Issue 3, March 2025.
In this study, the effect of carbon content on the microstructure of three Fe–Cr–Ni duplex steels produced by rapid solidification is evaluated. In this research, using scanning electron microscopy and transmission electron microscopy for microstructural analyses, it is revealed that carbon additions change the microstructure formation from primary ...

Study on Cutting Form and Surface Machining Quality of Wheel Tread under Reprofiling

Advances in Materials Science and Engineering, Volume 2017, Issue 1, 2017., 2017
The wheelset maintenance cost is an important part of train maintenance cost. Researchers and railway operators have been closely concerned about the way to minimize residual stress at wheel tread and surface roughness during wheel reprofiling, thereby reducing the wheel damage during operation, extending the wheelset service life, and cutting down ...

Compound sawtooth study in ohmically heated TFTR plasmas [PDF]

, 1985
Compound sawtooth activity has been observed in ohmically heated, high current, high density TFTR plasmas. Commonly called ''double sawteeth,'' such sequences consist of a repetitive series of subordinate relaxations followed by a main relaxation with a ...

Vertical Electron Cyclotron Emission Diagnostic for TCV Plasmas

EPJ Web of Conferences, 2012
Electron cyclotron resonance heating (ECRH) and electron cyclotron current drive (ECCD) are used to heat the plasma, to tailor the current profiles and to achieve different operating regimes of tokamak plasmas. Plasmas with ECRH/ECCD are characterized by

An Attention‐Based Detection Method of Fatigue Cracks on Steel

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Steel structures are susceptible to fatigue cracking under cyclic loading, which can lead to catastrophic structural failure. In the incipient phase of crack propagation, the width of fatigue cracks typically measures less than 0.1 mm, making them difficult to detect using standard imaging techniques.

An Investigation of Acoustic Attenuation Performance of Silencers with Mean Flow Based on Three‐Dimensional Numerical Simulation

Shock and Vibration, Volume 2016, Issue 1, 2016., 2016
Transmission loss (TL) is often used to evaluate the acoustic attenuation performance of a silencer. In this work, a three‐dimensional (3D) finite element method (FEM) is employed to calculate the TL of some representative silencers, namely, circular expansion chamber silencer and straight‐through perforated pipe silencer.
