However, existing satellite LST products face trade-offs between spatial and temporal resolutions, making it challenging to provide all-weather LST with high spatiotemporal resolution. In this study, focusing on Chengdu city, a framework combining a spatiotemporal fusion model and machine learning algorithm was proposed and applied to retrieve hourly high spatial resolution LST data from Chinese geostationary weather satellite data and multi-scale polar-orbiting satellite observations.

Multifunctional all-dielectric quarter-wave plate metasurfaces for generating focused vector beams of Bell-like states.

The generation of vector beams using metasurfaces is crucial for the manipulation of light fields and has significant application potential, ranging from classical physics to quantum science. This paper introduces a novel dielectric metasurface composed of quarter-wave plate (QWP) meta-atoms, known as a QWP metasurface, designed to generate focused vector beams (VBs) of Bell-like states under right circularly polarized illumination. The propagation phase imparted on both the co- and cross-polarized components of the output field constructs hyperbolic and helical phase profiles with topological charge , whereas the Pancharatnam-Berry (PB) phase acts only on the cross-polarized component to construct another helical phase profile with topological charge .

The role of DUOXA2 in the clinical diagnosis of paediatric congenital hypothyroidism.

: Congenital hypothyroidism (CH) is a common metabolic disorder in children that can impact growth and neurodevelopment, particularly during infancy and early childhood. DUOXA2, a DUOX maturation factor, plays a crucial role in the maturation and activation of dual oxidase DUOX2 (a member of the NADPH oxidase family). DUOX2 can correctly migrate to the plasma membrane from the endoplasmic reticulum (ER) with the help of DUOXA2, and the two proteins together form a stable complex that promotes hydrogen peroxide (H2O2) generation in the synthesis of thyroid hormones.

Robust and fast coarse frequency offset estimation based on frequency-domain skewness for coherent DSCM systems under severe bandwidth limitations.

A novel, to the best of our knowledge, frequency offset estimation (FOE) scheme is proposed and demonstrated for coherent digital subcarrier multiplexing (DSCM) systems, where frequency offset (FO) leads to severe filtering damage of subcarriers due to bandwidth limitations. The scheme exploits the symmetry of the signal spectrum, which naturally arises from the transmitter's frequency response and introduces frequency skewness as a cost function to search for FO. To achieve fast FOE, the false position (FP) method is employed to iteratively compute frequency shifts.

Carbon dots are emerging luminescent nanomaterials that have drawn considerable attention due to their abundance, environmental friendliness, and customizable optical properties. However, their susceptibility to temperature-induced vibrational exciton changes and the tendency to thermal quenching of emission have hindered their practical applications. Here, a method is reported for achieving high-temperature photoluminescence carbonized polymer dots (CPDs) through a bi-confinement approach that involves a highly cross-linked polymer network and a rigid AlO matrix.

Stabilized Oxygen Vacancy Chemistry toward High-Performance Layered Oxide Cathodes for Sodium-Ion Batteries.

Anionic redox has emerged as a transformative paradigm for high-energy layered transition-metal (TM) oxide cathodes, but it is usually accompanied by the formation of anionic redox-mediated oxygen vacancies (OVs) due to irreversible oxygen release. Additionally, external factor-induced OVs (defined as intrinsic OVs) also play a pivotal role in the physicochemical properties of layered TM oxides. However, an in-depth understanding of the interplay between intrinsic and anionic redox-mediated OVs and the corresponding regulation mechanism of the dynamic evolution of OVs is still missing.

Ferroptosis exacerbates the clonal deletion of virus-specific exhausted CD8 T cells.

During chronic infection or tumorigenesis, persistent antigen stimulation contributes to the exhaustion of CD8 T cells. Nevertheless, exhausted CD8 T (T) cells still preserve certain effector function, and maintaining a reservoir of exhausted cells is of vital importance for virus elimination and tumor eradiation. Despite considerable work interrogating the rejuvenation of T cells, mechanisms underpinning the clonal deletion of T cells remain largely unexplored over the past decade.

Enhanced Basal-Plane Catalytic Activity of MoS by Constructing an Electron Bridge for High-Performance Lithium-Sulfur Batteries.

MoS is a promising sulfur host material for lithium-sulfur (Li-S) batteries, but its low conductivity and limited active edge sites largely inhibit the catalytic activity toward the conversion of lithium polysulfides (LiPSs). Herein, we propose an electron bridge strategy by combining interlayer structure modification and electronic modulation to activate the basal-plane catalytic activity of MoS for the highly efficient catalytic conversion of LiPSs. As validated by experimental characterizations and theoretical calculations, the proposed strategy not only creates a conductive network but also induces delocalized electron redistribution within the MoS basal planes, leading to facilitated interfacial charge transfer kinetics and accelerated LiPSs redox kinetics.
