Multi-Omics Analysis Reveals Adaptive Strategies of Meconopsis horridula to UV-B Radiation in the Qinghai-Tibet Plateau.

Meconopsis horridula, an endemic medicinal and alpine horticultural species of the Qinghai-Tibet Plateau, exhibits remarkable adaptation to high-altitude UV-B radiation. Despite its ecological and medicinal significance, the mechanisms underlying its UV-B adaptation remain poorly understood. Here, we used a PacBio full-length transcriptome as a reference, integrating RNA-seq and metabolomic data from altitudinal populations, with field-based transcriptomic and microbiome profiling under shade-controlled UV-B gradients, to elucidate UV-B adaptive regulatory networks.

Exploration of physical activity, sedentary behavior and insulin level among short sleepers.

Background: Sufficient physical activity and sleep duration are essential for overall health. While one-third of the US population reports short sleep (<7 h), which is proven to link with negative health status. Current evidence on the relationship between physical activity, sedentary behavior, and serum insulin level in short sleep groups is limited.

Revisiting calculation of tilt angles for double-tilt sample holders in transmission electron microscopes.

We revisited the formula related to the overall tilt angle of a specimen using a side-entry double-tilt sample holder in a transmission electron microscope. Initially, we examined existing formulas in the literature for calculating the overall tilt angle. Subsequently, a new formula was derived, proven to better account for the actions of the double-tilt holder, thereby providing improved accuracy in the calculation.

Comparison of two methods for determination of crystal orientation using two Kikuchi pairs in electron diffraction patterns.

Kikuchi diffraction pattern analysis is one of the essential techniques of transmission electron microscopy used in materials science. For instance, one important application is its use in crystal orientation determination. During the development of SAKI5 software for the simulation and analysis of Kikuchi patterns, two methods in the literature for crystal orientation determination from two independent Kikuchi pairs have been revisited and then implemented.

[Correlation between highest point of greater trochanter and the ideal entry point for antegrade femoral nailing by three-dimensional images].

Objective: To provide reference of the ideal entry point for antegrade femoral nailing according to analysis correlation between highest point of greater trochanter and the middle line of the medullary cavity in adults by three-dimensional images.

Methods: From January 2016 to January 2017, 107 adults who underwent continuous computed tomography (CT) scans were ultimately enrolled, including 64 males and 43 females with an average age of (51.7±16.

Chiral Magnetism and High-Temperature Skyrmions in B20-Ordered Co-Si.

Magnets with chiral crystal structures and helical spin structures have recently attracted much attention as potential spin-electronics materials, but their relatively low magnetic-ordering temperatures are a disadvantage. While cobalt has long been recognized as an element that promotes high-temperature magnetic ordering, most Co-rich alloys are achiral and exhibit collinear rather than helimagnetic order. Crystallographically, the B20-ordered compound CoSi is an exception due to its chiral structure, but it does not exhibit any kind of magnetic order.

Magnetism of new metastable cobalt-nitride compounds.

The search for new magnetic materials with high magnetization and magnetocrystalline anisotropy is important for a wide range of applications including information and energy processing. There is only a limited number of naturally occurring magnetic compounds that are suitable. This situation stimulates an exploration of new phases that occur far from thermal-equilibrium conditions, but their stabilization is generally inhibited due to high positive formation energies.

New type of Al-based decagonal quasicrystal in Al60Cr20Fe10Si10 alloy.

A new kind of decagonal quasicrystal (DQC) with a periodicity of 1.23 nm was observed in the as-cast quaternary Al60Cr20Fe10Si10 alloy. The intensity distribution of some spots in the selected-area electron diffraction pattern along the tenfold zone axis was found to be different from other Al-based DQCs.

Structural and magnetic evolution of bimetallic MnAu clusters driven by asymmetric atomic migration.

The nanoscale structural, compositional, and magnetic properties are examined for annealed MnAu nanoclusters. The MnAu clusters order into the L1(0) structure, and monotonic size-dependences develop for the composition and lattice parameters, which are well reproduced by our density functional theory calculations. Simultaneously, Mn diffusion forms 5 Å nanoshells on larger clusters inducing significant magnetization in an otherwise antiferromagnetic system.

Cluster synthesis and direct ordering of rare-earth transition-metal nanomagnets.

Rare-earth transition-metal (R-TM) alloys show superior permanent magnetic properties in the bulk, but the synthesis and application of R-TM nanoparticles remains a challenge due to the requirement of high-temperature annealing above about 800 °C for alloy formation and subsequent crystalline ordering. Here we report a single-step method to produce highly ordered R-TM nanoparticles such as YCo(5) and Y(2)Co(17), without high-temperature thermal annealing by employing a cluster-deposition system and investigate their structural and magnetic properties. The direct ordering is highly desirable to create and assemble R-TM nanoparticle building blocks for future permanent-magnet and other significant applications.
