An Improved Fast Computational Method for Vibration Characteristic Analysis of Dry‐Type Iron Core Reactor

High Voltage, EarlyView.
ABSTRACT Structural mechanics field simulation plays a critical role in the vibration characteristic analysis of electrical equipment. Existing structural field analysis of equipment based on numerical simulation faces challenges such as convergence difficulties and prolonged computational time, failing to meet the demand for real‐time prediction of ...

Shaped electrodes for adaptive X‐ray optics

Journal of Synchrotron Radiation, EarlyView.
For adaptive X‐ray optics on high‐performance beamline optical systems, we describe an approach to mirror figure and slope control using patterned, shaped electrodes to control the local curvature on a lithium niobate substrate from a single applied voltage. Longitudinally continuous electrode patterns achieve target shapes without discontinuities, and

Air attenuation of high power XFEL beams

Journal of Synchrotron Radiation, EarlyView.
The transmission of air, which is used to contain X‐ray beams for radiation safety, is observed to significantly increase with X‐ray power.The Linac Coherent Light Source II, a high‐repetition‐rate X‐ray free‐electron laser (FEL), produces high average power as well as high peak power.

What Happens After Menopause (WHAM)? A Progress Report of a Prospective Controlled Study of Women After Pre‐Menopausal Risk‐Reducing Bilateral Salpingo‐Oophorectomy

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Surgical menopause, the removal of both ovaries prior to natural menopause, may impact short‐and long‐term physical and emotional health. An increasingly common cause of surgical menopause is risk‐reducing salpingo‐oophorectomy (RRSO) in those at high inherited risk of ovarian cancer.

A New Model of Feeding Biomechanics Based on Tied‐Arch Principles

Integrative Zoology, EarlyView.
This new biomechanical model explains the major stress and strain patterns generated through the cranium during biting. The model proposes that the cranium resolves bite‐induced reaction forces through arcs of compressive stress that span the cranial structure between biting teeth and both jaw joints.

Effect of Implant Design on Fracture Resistance, Mode, and Crystal Structure of One‐ and Two‐Piece Zirconia Implants With Ceramic or Titanium Abutment Screws: An In Vitro Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To evaluate the fracture resistance, fracture modes, and crystalline phase changes of zirconia one‐piece implants (OPI) and bone‐level (BLTPI) or tissue‐level, two‐piece implants (TLTPI), with ceramic (C) or titanium (T) abutment screws after dynamic preloading in a moist environment.

Biomechanical Analysis of 3D Printed and Thermoformed EVA Custom‐Made Mouthguard: Experimental and Finite Element Analyses

Dental Traumatology, EarlyView.
ABSTRACT Background/Objective 3D printed materials have been evaluated for fabricating mouthguards; however, little is known about their biomechanical performance in preventing dental trauma. This study aimed to compare two 3D printed polymers and three ethylene vinyl acetate (EVA) sheets used for mouthguard fabrication regarding their mechanical ...
