Cumulative Damage and Life Prediction Models for High-Cycle Fatigue of Metals: A Review

open access: yesMetals, 2021
Fatigue design of engineering structures is typically based on lifetime calculation using a cumulative damage law. The linear damage rule by Miner is the universal standard for fatigue design even though numerous experimental studies have shown its ...

Investigation of Advanced Lifetime Calculation Procedure for Steam Turbines in Flexible Operation [PDF]

open access: yes, 2017
At high intermittent renewable energy share, plants are forced to operate more flexible beyond their original design intent. Many plants are older than 30 years with only limited residual lifetime.

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

Minority carrier lifetime mapping of solar cells [PDF]

open access: yes, 2011
The minority carrier lifetime distribution across silicon solar cells was investigated using variations of the open circuit voltage decay method. This was performed on monocrystalline, polycrystalline and amorphous silicon solar cells. Light from a white

Excitation and breakup of [pi]+[pi]--atoms at high energies [PDF]

open access: yes, 2003
The DIRAC collaboration at CERN currently aims at measuring the lifetime of pionium (π + π − -atoms) with an accuracy of 10%. This is a crucial test of Chiral Perturbation Theory which predicts the lifetime to be (2.9 ± 0.1) fs.

Two Approaches to the Problem of High-cycle Fatigue of Materials and Structures

open access: yesMATEC Web of Conferences, 2019
Creation of new types of materials and development of new methods aimed at extending the lifetime of structures are two interconnected approaches to solve the problem of metallic structures fatigue.

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...

Positron Lifetime Calculation for Plastic Deformed Nanocrystalline Copper [PDF]

open access: yes, 2017
Positron lifetime calculation has been performed on a computer-generated nanocrystalline copper with a mean grain size of 9.1 nm during its deformation. For the undeformed and deformed nanocrystalline copper, calculated positron lifetimes are around 157 ...
