Statistical Theory of Multi-stage Newton Iteration Algorithm for Online Continual Learning

We focus on the critical challenge of handling non-stationary data streams in online continual learning environments, where constrained storage capacity prevents complete retention of historical data, leading to catastrophic forgetting during sequential task training. To more eff...

The mechanism of vascular injury caused by polystyrene microplastics: Involving ferroptosis and metabolomics

Polystyrene microplastics (PS-MPs) are environmental pollutants linked to cardiovascular diseases. This study investigated PS-MP-induced vascular toxicity mechanisms in mice. Mice were divided into saline control, low/medium/high PS-MP exposure (0.1, 1, and 10 mg/kg/d), and PS-MP...

Assessing ecosystem service values responses to livelihood transitions in an Arid Mountain–Oasis–Desert system

Balancing ecological conservation and rural livelihoods represents a critical challenge in arid social-ecological systems. Livelihood transitions among agropastoral households strongly influence the area allocated to different land-use types, thereby shaping regional ecosystem se...

Inulin-modified nano selenium biocomposite with dual-targeting capability mitigates polystyrene nanoplastic-induced hepatic ferroptosis

The mutually benefiting relationship between the environment and human health is under threat from the rapid accumulation and trophic transfer of fragmented plastics. While the in vivo presence and adverse effects of nanoplastics in the environment have been increasingly document...

Subjective well-being mediates and mindfulness moderates the relationship between perceived discrimination and altruistic behavior in college students with financial difficulties

Altruistic behavior is an essential positive psychological trait for college students. College students with financial difficulties are more likely to perceive discrimination, which may decrease their altruistic behavior, hindering personal growth and social stability. Our study...

Q-DRFormer: Query-Position Mapping Flow Prediction with Progressive Refinement for Document Rectification

Document image rectification aims to restore images degraded by geometric distortions. Existing U-shaped encoder-decoder methods rely on hierarchical upsampling operations to recover dense flow fields, which provide limited control over the displacement at individual grid positio...

Dark matter from the Weyl projection of bulk matter in five-dimensional gravity

We propose that the dark matter inferred in galaxies arises from the Weyl projection of bulk matter in five-dimensional gravity onto a brane. We derive the projected Einstein equations, the Abel-inversion kernel, and a near-cold equation of state, and show that a two-parameter mo...

Increasing risk of vapor pressure deficit exceeding critical thresholds for tree growth

With global warming, rising atmospheric vapor pressure deficit (VPD) has emerged as a critical driver of vegetation productivity and the terrestrial carbon sink. Yet, the thresholds beyond which VPD constrains tree growth remain poorly quantified. Using 2,953 tree-ring sites and...

PIK3CA promotes hepatic tumor growth through evasion of phagocyte-mediated anti-tumor immunity

Both primary and metastatic liver cancers are highly lethal diseases, for which effective treatment options remain limited. The unique hepatic microenvironment provides a niche that enables tumor cells to evade immune surveillance. To identify factors that mediate tumor growth wi...

Hydrochemistry and modeling nitrate concentration in farmland groundwater under different hydrological seasons by integrating hybrid quantum-classical ML, virtual sample generation and AlphaEarth Foundation

Abstract. Precise seasonal prediction of groundwater nitrate concentrations in intensive agricultural areas faces challenges such as data sparsity, strong spatiotemporal heterogeneity, and complex hydro-biogeochemical processes. To address these issues, this study proposes an int...

Unravelling the Atomic‐Scale Surface Chemistry for Intrinsically Bright and Stable Luminescence in CdSe Quantum Platelets

Two-dimensional colloidal CdSe quantum platelets (QPLs) represent a promising class of next-generation luminescent materials, yet the atomic-level surface chemistry that governs their optoelectronic properties remains poorly understood. In this study, we combine ligand passivatio...

Educating the World About China: Pedagogy and Public Diplomacy

Public diplomacy, governments communicating with publics abroad (and at home), can be construed as a form of education and is likely to benefit from the application of established principles of pedagogy. Western public opinion has turned against China despite, or possibly because...

Development of an explainable machine learning model for predicting six-month consciousness recovery in patients with prolonged disorders of consciousness

With advances in emergency care systems, the number of patients with prolonged disorders of consciousness (pDoC) has markedly increased. To optimize the allocation of healthcare resources and mitigate risks, the early and accurate identification of recovery potential in pDoC is e...

Does intergenerational income upward mobility increase the subjective well-being of middle-aged and older people in China?—Evidence from the China Family Panel Studies (CFPS)

Intergenerational income mobility is widely regarded as a key indicator of social vitality and opportunity, yet its consequences may extend beyond the mobile individuals themselves. Using 3956 parent–child pairs from the China Family Panel Studies, this study examines whether adu...

On stochasticity of zonostrophic instability

This paper concerns the behaviour of reduced models for turbulence–mean-flow interactions, in particular for the modelling of zonostrophic instability, which accounts for the spontaneous generation of zonal flows observed in many planetary and geophysical fluid systems. In modell...

School-Based Versus Clinic-Based Interventions for PTSD in Children and Adolescents: A Systematic Review and Meta-Analysis on Their Differences in Effectiveness and Retention Rate

This systematic review and meta-analysis was conducted across multiple databases, including MEDLINE, PsycINFO, EMBASE, ERIC, PubMed, SCOPUS, Web of Science, the Published International Literature on Traumatic Stress, Cochrane Central Register of Controlled Trials, China National...

Iterated Agent for Symbolic Regression

Abstract Symbolic regression (SR), the automated discovery of mathematical expressions from data, is a cornerstone of scientific inquiry. However, it is often hindered by the combinatorial explosion of the search space and a tendency to overfit. Popular methods, rooted in genetic...

Increased maximum carbon release offsets half of the growth trend in annual land carbon sink

The terrestrial carbon sink has strengthened in recent decades through enhanced maximum CO2 uptake (MCU) and a longer carbon uptake period (CUP), whereas maximum CO2 release (MCR) remains less quantified. Using atmospheric inversion estimates and 16 terrestrial biosphere models,...

Household food-related consumption resources, self-reported vigorous activity, and incident depressive symptoms among middle-aged and older Chinese adults: a longitudinal CHARLS study

Physical activity is generally associated with lower depression risk, but an intensity-only questionnaire cannot distinguish the context in which activity occurs. We examined whether considering household food-related consumption alongside a self-reported vigorous-activity indica...
