Eddy evolution during large dust storms [PDF]

Icarus, 338 (2020), 2019
The evolution of eddy kinetic energy during the development of large regional dust storms on Mars is investigated using the Mars Analysis Correction Data Assimilation (MACDA) reanalysis product and the dust storm data derived from Mars Global Surveyor Mars Daily Global Maps.

3D Printed Optics Achieves Broadband Structured Light

Advanced Optical Materials, EarlyView.
The arbitrary creation of structured light often requires complex design and fabrication steps and is largely limited to single wavelength. By leveraging off the toolkit for digital holograms, how complex amplitude modulation can be implemented as 3D printed optics in a manner that is broadband is shown, for the creation of multiwavelength forms ...

Characterization of dust activity on Mars from MY27 to MY32 by PFS-MEX observations [PDF]

, 2018
We present spatial and temporal distributions of dust on Mars from Ls = 331 in MY26 until Ls = 80 in MY33 retrieved from the measurements taken by the Planetary Fourier Spectrometer (PFS) aboard Mars Express. In agreement with previous observations, large dust opacity is observed mostly in the southern hemisphere spring/summer and particularly over ...

Pan‐Variant SARS‐CoV‐2 Vaccines Induce Protective Immunity by Targeting Conserved Epitopes

Advanced Science, EarlyView.
An integrative approach identifies conserved B‐cell and T‐cell epitopes within SARS‐CoV‐2 proteins, redirecting immune responses from variable to conserved regions. These epitopes elicit robust humoral and cellular immunity, neutralizing diverse viral variants. Promiscuous T‐cell epitopes demonstrate cross‐species efficacy, highlighting their potential

Enrichment of hepatic glycogen and plasma glucose from H₂18O informs gluconeogenic and indirect pathway fluxes in naturally feeding mice

NMR in Biomedicine, Volume 36, Issue 2, February 2023., 2023
18O‐enrichment of liver glycogen, triglyceride glycerol, and blood glucose of mice given 18O‐water during overnight feeding was quantified by 13C NMR and MS. Glycogen 18O‐enrichment of oxygens 3, 5, and 6 from isotope‐shifted 13C signals informed indirect pathway contributions from different sources.

Dust particle size, shape, and optical depth during the 2018/MY34 Martian Global Dust Storm retrieved by MSL Curiosity rover navigation cameras [PDF]

, 2020
Martian planet-encircling dust storms or global dust storms (GDS), resulting from the combined influence of local and regional storms, are uncommon aperiodic phenomena: with an average frequency of approximately one every 3-4 MY, they produce a substantial rise in the atmospheric dust loading that lasts from weeks to months and have a significant ...

Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation

Advanced Science, EarlyView.
Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...

Chemical characteristics and source apportionment of particulate matter (PM2.5) in Dammam, Saudi Arabia: Impact of dust storms

Atmospheric Environment: X, 2022
Atmospheric particulate matter (PM) is known to be harmful to human and environmental health, with factors including particle size and composition thought to be key drivers of toxicity. Understanding the composition and hence sources of PM is critical to

Application of a Self-Organizing State Space Model to the Leonid Meteor Storm in 2001 [PDF]

2003, PASJ, 55, 535, 2012
The Leonids show meteor storms in a period of 33 years, and known as one of the most active meteor showers. It has recently shown a meteor stream consisting of several narrow dust trails made by meteoroids ejected from a parent comet. Hence, an analysis of the temporal behavior of the meteor flux is important to study the structure of the trails ...

In Vivo Reprogramming of Tissue‐Derived Extracellular Vesicles for Treating Chronic Tissue Injury Through Metabolic Engineering

Advanced Science, EarlyView.
Inspired by exercise‐induced metabolic rewiring and EV secretion, this study shows that in vivo metabolic engineering strategy can reprogram EV secretion pattern and simultaneously attenuate multiple tissue injury in CKD status, highlighting that it is a potential strategy for treating diverse chronic diseases.
