Cyclic Oxidation of High Mo, Reduced Density Superalloys

Metals, 2015
Cyclic oxidation was characterized as part of a statistically designed, 12-alloy compositional study of 2nd generation single crystal superalloys as part of a broader study to co-optimize density, creep strength, and cyclic oxidation.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).

Superior vena cava obstruction after the Glenn procedure

Autopsy and Case Reports, 2019
Acute obstruction of superior vena cava anastomosis right after the Glenn procedure may lead to tragic consequences. We describe the case of a one-year-old child with tricuspid atresia and a previous Blalock-Taussig shunt procedure, who presented severe ...

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications

Advanced Materials Technologies, EarlyView.
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...

Is Youth's Engagement in Agribusiness an Opportunity or a Necessity? A Closer Look at the Situation in South Kivu, Eastern Democratic Republic of the Congo

Agribusiness, EarlyView.
ABSTRACT Despite the broad focus on necessity‐ and opportunity‐driven entrepreneurship in research and policy, the entrepreneurial dichotomy within the agribusiness context has not been adequately addressed. This study contributes to closing this knowledge gap by examining youth's perceptions of agribusiness through the lens of the push‐pull motivation

Operational Testing of 4H-SiC JFET ICs for 60 Days Directly Exposed to Venus Surface Atmospheric Conditions

IEEE Journal of the Electron Devices Society, 2019
Prolonged Venus surface missions (lasting months instead of hours) have proven infeasible to date in the absence of a complete suite of electronics able to function for such durations without protection from the planet's extreme conditions of ~460°

First Report of Uniparental Isodisomy of Chromosome 15 Revealing Angelman Syndrome and Microphthalmia Associated With a Novel Homozygous ALDH1A3 Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Paternal isodisomy of chromosome 15 (iUPD15) is a recognized cause of Angelman syndrome (AS), accounting for approximately 2%–5% of cases. Additionally, another recognized consequence of iUPD is the unmasking of autosomal recessive disorders. However, reports of recessive disorders resulting from iUPD15 remain scarce in the literature.
