World Beliefs Moderate the Effects of Trauma and Severe Illness on Emotional Distress

open access: yesJournal of Personality, EarlyView.
ABSTRACT Objective Severe illness and trauma can cause significant psychological distress, but individuals differ in their responses. This research tested whether world beliefs—fundamental assumptions about the nature of the world—moderate the relationship between negative life experiences and emotional distress.

New Boost-Type PFC MF-Vienna PWM Rectifiers with Multiplied Switching Frequency

open access: yesAdvances in Electrical and Computer Engineering, 2015
In this paper new three-level boost-type PFC PWM rectifiers with Multiplied-switching-Frequency (MF) are presented. They can work both at high and low switching frequency for single- and for three-phase unity-power-factor applications.

A Space Vector Switching Pattern Hysteresis Control Strategy in VIENNA Rectifier

open access: yesIEEE Access, 2020
The conventional hysteresis current control (C-HCC) in VIENNA rectifier is one of the simplest and economic strategies. However, current harmonics content and switching number are high, and the coupling among the three-phase cannot be eliminated.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Factors Associated With Rectal Spacer Use in Prostate Cancer Patients Receiving Radiation Therapy

open access: yesCancer Medicine, Volume 15, Issue 5, May 2026.
ABSTRACT Background/Objective Prostate cancer is a leading cause of cancer‐related death among men in the United States. However, the influence of demographic, socioeconomic, regional, and treatment‐related factors on rectal spacer use among men treated with radiation therapy remains largely unexplored in the literature.
