A probabilistic interpretation of the Miner number for fatigue life prediction

Fracture and Structural Integrity, 2014
The Miner number M, used as a tool for lifetime prediction of mechanical and structural components in most of the standards related to fatigue design, is generally accepted as representing a damage stage resulting from a linear progression of damage ...

The Cumulative and Damaging Effects of Discrimination

Du Bois Review: Social Science Research on Race, 2023
AbstractThis study examines the racialized and gendered experiences of Black men (N = 20) from elementary school through graduate school. The Black men featured in this article are current STEM doctoral students and were asked to reflect on their K-12 and undergraduate STEM experiences as well as their current experiences as graduate students.

Misperception of Body Weight After Childhood Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Misperception of body weight can negatively impact the weight management efforts of childhood cancer survivors (CCSs). Both being overweight or underweight are associated with chronic health conditions commonly observed in CCS; therefore, accurate weight perception is critical for reducing long‐term health risks.

Experimental study on progressive failure of anchoring structure under high-frequency and low-energy impact disturbance

Meitan xuebao
High-frequency, low-energy impacts consistently inflict damage on the surrounding rock and anchoring structure in deep roadways, leading to ongoing instability. The construction of anchoring support system that can withstand these dynamic impact loads is

On Hierarchical Composite Endpoints in Pediatric Cancer Supportive Care: Illustrative Examples From Two Multi‐Center Phase‐III Randomized Clinical Trials

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric supportive care clinical trials often involve multiple clinically important outcomes, complicating trial interpretation. Hierarchical composite endpoints (HCEs) provide a framework to integrate key outcomes according to clinical importance.

A Population‐Based Study on Childhood Aplastic Anemia—Incidence, Outcomes, and Health‐Related Quality of Life

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Childhood aplastic anemia (AA) is a rare disease, and both the disease itself and its treatment cause significant morbidity. We aimed to determine the contemporary incidence of childhood AA in Finland, to compare the clinical characteristics of AA against inherited bone marrow failure syndromes (IBMFS) and refractory cytopenia of ...

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...

A Simplified Methodology to Evaluate the Design Specifications of Hydraulic Components

Applied Sciences, 2018
The fatigue of a hydraulic component inherently varies due to various factors that can be divided into two categories: structural and load spectrum variability. The effects of both variabilities must be considered when determining fatigue life.
