Phase-Specific Damage Tolerance of a Eutectic High Entropy Alloy
Article describes how phase-specific damage tolerance was investigated for the AlCoCrFeNi2.1 high entropy alloy with a lamellar microstructure of L12 and B2 phases. Distinct differences in micro-scale deformation mechanisms were reflected in post-compression fractography, with L12-phase cantilevers showing typical characteristics of ductile failure, including the activation of multiple slip lanes, shear lips at the notch edge, and tearing inside the notch versus quasi-cleavage fracture with cleavage facets and a river pattern on the fracture surface for the B2-phase cantilevers.

Reconstructing horizontal gene flow network to understand prokaryotic evolution
Article says that horizontal gene transfer (HGT) is a major source of phenotypic innovation and a mechanism of niche adaptation in prokaryotes. Methods for detecting HGT can be classified into phylogenetic-based and parametric or composition-based approaches, so authors exploited the complementary strengths of both the approaches to construct a high confidence horizontal gene flow network. The scale-free horizontal gene flow network presented here provides new insights into modes of transfer for the exchange of genetic information and also illuminates differential gene flow across phyla.

Patch characteristics and domestic dogs differentially affect carnivore space use in fragmented landscapes in southern Chile
This article's aim is to determine whether (a) the spatial use of domestic dogs increases with habitat destruction, and (b) domestic dogs and habitat destruction drive the spatial use of native carnivores in a heavily degraded agricultural landscape. Conclusions highlight that domestic dog occupancy was positively correlated with habitat loss and future conditions of increased fragmentation and habitat loss will likely increase the potential contact between domestic dogs and native carnivores.

Acoustic Metasurface-Aided Broadband Noise Reduction in Automobile Induced by Tire-Pavement Interaction
Article demonstrating a technique utilizing acoustic metasurfaces (AMSes) with high reflective characteristics using relatively lightweight materials for noise reduction without any change in mechanical strength or weight of the tire. The proposed design can significantly reduce the noise arising from tire–pavement interaction over a broadband of acoustic frequencies under 1000 Hz and over a wide range of vehicle speeds using a negative effective dynamic mass density approach.
