Minimization of Porosity in E11018‐G Low‐Alloyed Steel Processed by Laser Powder Directed Energy Deposition

steel research international, EarlyView.
The processability of the E11018‐G by laser powder directed energy deposition (LP‐DED) is investigated. The effects of powder moisture, ambient humidity, and laser remelting on LP‐DED parts’ porosity are shown. A strong influence of the atomizing gas is observed.

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

Structural Concrete, EarlyView.
Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a

Dynamic coronary roadmap-guided PCI reduces contrast volume and radiation time compared to standard angiography PCI: A meta-analysis

Heliyon
Background: Dynamic Coronary Roadmap (DCR) is a new PCI method that may reduce contrast dose and contrast-associated acute kidney injury (CA-AKI) risk. This paper evaluates DCR-guided PCI versus standard angiography PCI for contrast usage, procedure time,

Sequence of Immunological Events During IgE‐Mediated Allergic Reactions to Food

Allergy, EarlyView.
ABSTRACT Food allergies (FA) represent a significant global health burden. Upon allergen re‐exposure, allergic patients exhibit a sequence of symptoms that vary in terms of affected organ systems, severity, time of onset and allergen reactivity thresholds.

Grand canonical Gutzwiller approximation for magnetic inhomogeneous systems

, 2008
The Gutzwiller approximation (GA) for Gutzwiller-projected grand canonical wave functions with fugacity factors is investigated in detail. Our systems in general contain inhomogeneity and local magnetic moments.

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

Conservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

The FEBS Journal, EarlyView.
In Huh7 cells, HIF‐1α is essential as it maintains the expression of proteins involved in glycolysis and steroid/cholesterol biosynthesis both under normoxia and hypoxia. On the other hand, in HeLa cells, these pathways are induced by HIF‐1α only under hypoxia.
