Does Digitalization Widen Labor Income Inequality?

ABSTRACT We develop a growth model that endogenizes the occupational choice of workers with different ability levels to study how digitalization affects labor income inequality. The framework incorporates digitalization's multifaceted effects on the economy: (i) it influences eco...

Seasonal plant-microbial coupling regulates carbon transformation pathways and soil organic carbon persistence in alpine grasslands

To elucidate the seasonal mechanisms underlying soil carbon cycling in alpine grasslands, we collected soil profile samples (0–50 cm) from the Qinghai-Tibet Plateau (QTP) in May, August, and November. Amino sugars and lignin phenols were used as molecular markers of microbial-der...

Declining hydraulic safety in a drier world

Forests worldwide are increasingly exposed to soil drought under climate change, with their fates depending on the ability to maintain essential functions like water transport (hydraulics) and photosynthesis. Acclimation is expected to mitigate drought impacts, but the extent to...

Torsional wake stiffness and the dynamic response of tethered tandem cylinders in the subcritical and critical regimes

This study experimentally investigates the stationary and dynamic characteristics of a tandem cylinder configuration in which the downstream cylinder is confined to rotate about a pivot point centered at a fixed upstream cylinder with a specified cylinder-to-cylinder spacing. Res...

AMOC Weakening Controls δ 18 O but Not Rainfall in North China During Deglacial Abrupt Events

Abstract East Asian Summer Monsoon (EASM) varied at orbital and millennial timescales during the Last Deglaciation (∼20–11 ka). The uniform δ 18 O response in East China is often linked to EASM circulation that drives a precipitation dipole in North and South China on orbital sca...

Multi-omics profiling of migraine links plasma proteomic signatures with lipid metabolomic measures

Migraine is a highly prevalent neurological disorder with incompletely understood molecular mechanisms. We aimed to identify migraine-associated plasma proteins and lipid metabolomic measures and to investigate their relationships through an integrated multi-omics framework. This...

Deuterated Aprotic Electrolytes Enable Rechargeable Lithium Batteries With High (Electro)Chemical and Thermal Stability

ABSTRACT Electrolytes with exceptional (electro)chemical and thermal stability are essential prerequisites for high‐energy‐density rechargeable lithium batteries. Conventional aprotic ether and ester solvents contain polarizable C─H bonds that trigger parasitic proton transfer re...

Highly Stable CO 2 Methanation Catalyst Fabricated by Engineering Metal–Metal Oxide Interfaces of CoAlO x

ABSTRACT Preparation of a heterogeneous catalyst with ultra‐high catalytic stability and target product selectivity of > 99% at near thermodynamic equilibrium conversion is the ultimate goal to pursue in the catalysis field. Here, a CoAlO x catalyst is constructed for CO 2 methan...

Beyond the factor-driven paradigm: Spatiotemporal dynamics and system coupling of agricultural transition in Henan Province, China

The core of agricultural transition lies in changes to the various components of the agricultural systems and their interactions. Drawing on the social-ecological-technological systems (SETS) framework, this study developed an “element coupling–external manifestation” analytical...

Machine learning-enhanced 4DVar assimilation for winter wheat yield estimation

Context Accurate crop yield estimation is crucial for ensuring food security, promoting sustainable agriculture, and optimizing management practices. However, integrating remote sensing data with crop models remains challenging, largely due to the inability of traditional data as...

Modular flow of celestial conformal field theory

Abstract We first review the calculations for the modular flow and the vector flow of $$\text {CFT}_2$$ CFT 2 , warped CFTs and Bondi–Metzner–Sachs field theories (BMSFTs), and then we present the vector flows and modular flows in Celestial field theory and Klein CFTs. We also di...

Selective Hydrogenation of α,β‐Unsaturated aldehydes to Unsaturated alcohols: From Metal Nanoparticles to Nanoclusters and Single‐Atom Catalysts

The selective hydrogenation of α,β‐unsaturated aldehydes is a pivotal process for synthesizing fine chemicals, fragrances, and pharmaceuticals. However, achieving high chemoselectivity to unsaturated alcohols remains a significant challenge due to the thermodynamic and kinetic pr...

Ga Doping Enables (110) Facet Control and Surface Passivation of SnO 2 for Efficient and Stable Inverted Perovskite Solar Cells

ABSTRACT Perovskite solar cells (pero‐SCs) with inverted ( p–i–n ) architecture have advanced rapidly, yet combining high efficiency with long‐term operational stability remains challenging, mainly due to commonly used organic cathode buffer layer (CBL) (between C 60 electron tra...

Gut microbiome seasonality is associated with dietary plasticity and coexistence in three sympatric Pamir ungulates

This graphical abstract outlines a multi-omics framework investigating the seasonal dietary composition and gut microbial communities of three coexisting ungulate species inhabiting the extreme high-altitude Pamir Plateau (Ovis ammon polii, Capra sibirica, and Pseudois nayaur). B...

A Subtle Atmospheric Shift Is Redefining Winter Hydrology on the Tibetan Plateau

Abstract Winter climate over the Tibetan Plateau has long been characterized by cold conditions that preserve snow and regulate downstream water supply through delayed melt. Here we show that this buffering function is weakening in the Sanjiangyuan region due to a shift in winter...
