ABSTRACT Halide perovskites are promising for applications in light‐emitting diodes, multilevel anti‐counterfeiting, and radiation detection due to their excellent luminescence properties. Mn 2+ doping can further tailor the optical properties of perovskites, yet its microscopic...

Harmonizing A‑Site Cation Incorporation With Conductive Grain‑Boundary Bridging for Durable Perovskite Solar Cells

ABSTRACT While perovskite solar cells (PSCs) have achieved significant progress in power conversion efficiency ( PCE ), their commercialization remains hindered by a critical challenge: irreversible efficiency degradation during device operation, primarily caused by the spontaneo...

Microenvironment-aware transcriptome reconstruction in spatial transcriptomics

Abstract Imaging-based spatial transcriptomics offers single-cell resolution but measures limited panels dominated by identity-defining genes, leaving transcriptome-wide variation unobserved. Existing approaches for predicting unmeasured genes rely mainly on shared-gene alignment...

Noncollinear kagome magnet driven by giant antisymmetric exchange

Kagome lattices host exotic phenomena such as quantum spin liquids, topological Weyl nodes, and flat bands. The kagome ferromagnet Co3Sn2S2 has been a focus of debate due to conflicting reports on its magnetic character. Here, using weakly perturbative probes—primarily neutron sc...

Effects of different thinning intensities on Pinus tabuliformis transpiration and forest-water relations in the Loess Plateau of China

Thinning can improve the soil water conditions of forested land, decrease potential water stress, and enhance the drought resistance of trees by adjusting the stand density. However, the effect of thinning intensity on water consumption of plantations in semiarid regions remains...

A Comparative Study of Machine-Learning Methods for Early Classification from Sparse Astronomical Light Curves

The booming data volume of modern time-domain surveys demands fast, robust early classification of sparsely sampled light curves, as newly discovered transients typically have only a handful of observations. We compare classifiers for extremely sparse light curves (3–30 observati...

Land Transition Pathways Govern Carbon Storage Dynamics in an Olympic Host Region: A PLUS–InVEST Simulation in Yanqing District

Mega-events can accelerate land–use/land cover change (LULCC) through infrastructure development and ecological interventions, but the carbon consequences of different land transition pathways remain unclear. Using Yanqing District, a host region of the Beijing 2022 Winter Olympi...

How Much Water Can Be Seasonally Buffered by China's Largest Floodplain Lake? A Refined Estimate From SWOT

Abstract Poyang Lake, China's largest floodplain lake, plays a crucial role in regional hydrology by seasonally regulating water to mitigate floods and sustain extensive wetland ecosystems. However, complex hydrodynamics and significant spatial hydraulic gradients often invalidat...

Lakeshore transformation and water color dynamics: A satellite-based 23-year assessment of nine plateau lakes in Yunnan, China

Study region Nine plateau lakes in Yunnan, China. Study focus We developed an extended lakeshore utilization classification framework to categorize lakeshores as natural, agricultural, or artificial using fixed maximum shorelines. We then derived the Forel–Ule Index (FUI) of the...

Reconfigurable Terahertz Multi‐Harmonic Dual‐Combs
