Rheology of a Supercooled Polymer Melt

open access: yes, 1999
Molecular dynamics simulations are performed for a polymer melt composed of short chains in quiescent and sheared conditions. The stress relaxation function $G(t)$ exhibits a stretched exponential form in a relatively early stage and ultimately follows ...

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

open access: yesArthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

STRESS AND STRAIN STATE OF REPAIRING SECTION OF PIPELINE

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2015
Reliability of continuous operation of pipelines is an actual problem. For this reason should be developed an effective warning system of the main pipelines‘  failures and accidents not only in design and operation but also in selected repair.

Race and Household Income are Associated with Disease Outcomes in Pediatric Patients with ANCA‐associated Vasculitis Hospitalized in the United States

open access: yesArthritis Care &Research, Accepted Article.
Objectives Race and household income impact outcomes in patients with rheumatic conditions; however, their role in pediatric anti‐neutrophil cytoplasmic antibody (ANCA)‐associated vasculitis (AAV) remains poorly understood. We aimed to evaluate whether race/ethnicity and household income are associated with severe AAV disease and renal outcomes among ...

Plastic dislocation and incompatibility density as indicators for residual stresses [PDF]

open access: yes, 2019
Residual stresses in forming simulations are typically investigated by analyzing the remaining stress state after removing all external loadings. However, the generation of the stress state during forming remains unknown.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Material Properties Measurements for Selected Materials [PDF]

open access: yes
Hugoniot equation of state measurements were made on Coconino sandstone, Vacaville basalt, Kaibab limestone, Mono Crater, pumice and Zelux (a polycarbonate resin) for pressures to 2 Mb. A single data point was obtained for fused quartz at 1.6 Mb.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.
