Acetaldehyde oxidation at elevated pressure (open access)

Acetaldehyde oxidation at elevated pressure

A detailed chemical kinetic model for oxidation of CH3CHO at intermediate to high temperature and elevated pressure has been developed and evaluated by comparing predictions to novel high-pressure flow reactor experiments as well as shock tube ignition delay measurements and jet-stirred reactor data from literature. The flow reactor experiments were conducted with a slightly lean CH3CHO/O2 mixture highly diluted in N2 at 600–900 K and pressures of 25 and 100 bar. This is the accepted manuscript version of the published article.

Computational modeling of human reasoning processes for interpretable visual knowledge: a case study with radiographers (open access)

Computational modeling of human reasoning processes for interpretable visual knowledge: a case study with radiographers

Article proposing a computational method to quantify and dissect visual reasoning. The method characterizes spatial and temporal features and identifies common and contrast visual reasoning patterns to extract significant gaze activities. The visual reasoning patterns are explainable and can be compared among different groups to discover strategy differences. Empirical observations show that the method can capture the temporal and spatial features of human visual attention and distinguish expertise level. By revealing task-related reasoning processes, this method demonstrates potential for explaining human visual understanding.

Design approaches for printability-performance synergy in Al alloys for laser-powder bed additive manufacturing

This article highlights that design of Al alloys for laser-powder bed fusion (L-PBF) can lead to fundamental change in the microstructure evolution, proposed alloy design strategies lead to synergy between and printability and performance, hierarchical and heterogeneous microstructures have potential to overcome the strength-ductility tradeoff, and alloy design incorporating the specific attributes of an AM technology is crucial to maximizing its potential.

Dynamic Shear Deformation of a Precipitation Hardened Al0.7CoCrFeNi Eutectic High-Entropy Alloy Using Hat-Shaped Specimen Geometry (open access)

Dynamic Shear Deformation of a Precipitation Hardened Al0.7CoCrFeNi Eutectic High-Entropy Alloy Using Hat-Shaped Specimen Geometry

The article reports on the shear deformation of a eutectic structured HEA and effect of precipitation on shear deformation, particularly Al₀.₇CoCrFeNi high-entropy alloy (HEA). A split-Hopkinson pressure bar (SHPB) was used to compress the hat-shaped specimens to study the local dynamic shear response of the alloy. The change in the width of shear bands with respect to precipitation and deformation rates was studied. The precipitation of L1₂ phase did not delay the formation of adiabatic shear bands (ASB) or affect the ASB width significantly, however, the deformed region around ASB, consisting of high density of twins in fcc phase, was reduced from 80 µm to 20 µm in the stronger precipitation strengthened condition.

Effects of Low-Intensity Aerobic Exercise on Neurophysiological and Behavioral Correlates of Cognitive Function (open access)

Effects of Low-Intensity Aerobic Exercise on Neurophysiological and Behavioral Correlates of Cognitive Function

Article asserts that acute aerobic exercise exerts a small beneficial effect on cognition. Previous research primarily examines cognitive changes following a bout of exercise, while little is currently known about changes in cognitive performance during exercise. Authors state that the primary purpose of this study was to examine the effects of low-intensity cycling on cognitive function indexed by behavioral (response accuracy; reaction time) and neurocognitive (P3 mean amplitude; P3 centroid latency) responses.

Evidence of Endozoochory in Upland Geese Chloephaga picta and White-Bellied Seedsnipes Attagis malouinus in Sub-Antarctic Chile (open access)

Evidence of Endozoochory in Upland Geese Chloephaga picta and White-Bellied Seedsnipes Attagis malouinus in Sub-Antarctic Chile

This article evaluates the role of endozoochory in herbivorous and sympatric bird species in sub-Antarctic Chile. The authors hypothesize that fragments of bryophyte gametophytes retrieved from their feces are viable and capable of regenerating new plant tissue. This relationship may have important implications in the way bryophytes disperse and colonize habitats facing climate change.

FERONIA and wall-associated kinases coordinate defense induced by lignin modification in plant cell walls (open access)

FERONIA and wall-associated kinases coordinate defense induced by lignin modification in plant cell walls

Article discusses authors' findings that through genetic screening for suppressors of defense gene induction in the low lignin ccr1-3 mutant of Arabidopsis thaliana, we found that loss of function of the receptor-like kinase FERONIA, although not restoring growth, affected cell wall remodeling and blocked release of elicitor-active pectic polysaccharides as a result of the ccr1-3 mutation. They determine that engineering plant cell walls will require development of ways to bypass endogenous pectin signaling pathways.
