Mobility Control and Adsorption-Retention Behavior of an Engineered-Strain-Derived Microbial Polysaccharide in High-Temperature and High-Salinity Porous Media

Abstract Conventional polymers often undergo viscosity loss and performance deterioration in high-temperature and high-salinity reservoirs. A novel microbial polysaccharide system developed from an engineered oil-recovery strain exhibits good temperature and salt tolerance as wel...

Aesthetic preference and gaze-based visual attention in atlas-cover design: Evidence from an eye-tracking study

Atlas covers communicate thematic identity and shape first impressions, yet their design remains largely guided by heuristic experience rather than empirical evidence. Although eye-tracking research has examined map use, packaging design, and visual interfaces, little is known ab...

Twelve-Hour Dynamic Monitoring of Microalgae Response to Oxidative Stress by Single-Cell Metabolomics Analysis

Abstract Cellular metabolism is inherently dynamic during stress responses, yet conventional single-cell metabolomics workflows remain largely limited to isolated snapshots. Here, we implemented an online, label-free CyESI-MS-based workflow for the continuous monitoring of single...

Flexural dispersion curves of acoustoelastic borehole waves by the perturbation method in a triaxially stressed transversely isotropic formation with vertical symmetry

Abstract Cross-dipole acoustic logging is widely used to determine the maximum horizontal stress azimuth and stress imbalance in vertical boreholes within isotropic formations. However, theoretical analysis of dipole flexural dispersion under imbalanced stresses in transversely i...

Numerical Simulation Study on Unstable Water Injection in Shale Oil Reservoirs Considering Stress Sensitivity and Threshold Pressure Gradient

Unstable water injection is widely used in low-permeability shale oil reservoirs, but its performance under the combined effects of stress sensitivity and threshold pressure gradient remains uncertain. This study aims to determine how these two mechanisms jointly affect unstable...

A Type-I/II Photosensitizer with Cell Death Self-Reporting for Ferroptosis-Potentiated Photodynamic Theranostics against Large Tumors

Abstract Photodynamic therapy (PDT) with ferroptosis induction is a promising antitumor strategy, yet its efficacy is compromised by conventional photosensitizers limited to single-pathway ROS generation, particularly in large tumors. Herein, a series of D−A−D AIE photosensitizer...

Rethinking urban ecosystem service flow through human mobility: The neighborhood effect averaging problem

Daily exposure to ecosystem services (ES) plays an important role in improving urban residents' health; however, residents' actual contact with ES, referred to as ecosystem service flows, depends not only on local biophysical conditions of urban nature but also on human daily mob...

Interface-aware adaptive layer-wise physics-informed neural networks for multilayer large-strain consolidation: a benchmark of architectures, training strategies, and trade-offs

Multilayer large-strain consolidation in stratified soils involves nonlinear pore-pressure dissipation, evolving deformation, and material discontinuities, which pose significant challenges for physics-informed neural networks (PINNs). This study develops a layer-wise adaptive PI...

Early Ediacaran micro- and macro-fossils from South China provide insights into post-Snowball Earth marine ecosystem

Abstract Understanding of biological and ecological dynamics after the terminal Cryogenian Marinoan glaciation remains limited because the early Ediacaran fossil record is sparse and taphonomically biased toward microfossils. Here we show an early Ediacaran fossil assemblage from...

Elastically bendable chiral metal halide crystals

Metal halide single crystals exhibit superior optoelectronic properties, promising for applications in optics and energy. However, they are inherently brittle, which has posed a major challenge for use in flexible electronics. Here, we report the elastic bending in a family of ch...

Dual pathways controlling Mn-carbonate mineralization in redox-stratified basins: Geochemical constraints from the Ortokarnash deposit (Western Kunlun, China)

The formation of sedimentary manganese deposits—vital sources of a critical metal for green technologies—is intimately linked to redox-stratified basins, yet whether Mn-carbonates precipitate directly in anoxic water columns or form diagenetically in sediments has remained unreso...

Co-Occurrence and Interactions of Microplastics and Heavy Metals in Agricultural Soils: A Review

Agricultural soils are increasingly affected by the co-occurrence of heavy metals (HMs) and microplastics (MPs), but the conditions governing their combined behavior, metal mobility and bioavailability, remain insufficiently understood. This review synthesizes evidence on the co-...

Evidence from alkaline magmatism for fluorine- and bromine-enriched cratonic mantle roots

The base of cratonic lithospheric mantle (cratonic root) is a key volatile-rich reservoir (e.g., carbon and halogens), formed through long-term metasomatism by deep-derived incipient melts, whose reactivation has been proposed to drive climatic change over the course of Earth his...

The WoKaS-Iso database: workflow for a global compilation of oxygen-18 and deuterium records in karst springs and cave drip water for enhanced understanding of karst systems

For analysing karst hydrogeological systems, observations of karst springs and cave drips are considered indispensable. In addition to hydrometric observations, knowing the oxygen and hydrogen stable isotope ratios has improved the understanding of vadose zone and aquifer dynamic...

Shipboard core-storage platform for drillships: design, verification and field validation

For the pioneered shipboard automated core-transmission system (ACTS) on the ocean drillship Dream, the structural integrity and operational reliability of the storage rack subsystem are critical to core logistics efficiency. The shipboard subsystem module experiences pronounced...

Metasomatized mantle source and far-field effect of flat-slab subduction at the Huangtuliang gold deposit, northern margin of the North China Craton

The metasomatized lithospheric mantle has been proposed as the primary source for gold mineralization at cratonic margins, yet without much direct evidence. To substantiate this theory with geochemistry, we study ore-hosting alkaline syenite and mineralization-related lamprophyre...

Gluon condensate effects on heavy quarkonium spectral functions and thermal dissociation

Abstract We investigate how gluon condensate modifies thermal spectral functions and melting patterns of heavy vector mesons, specifically charmonium and bottomonium, using an improved soft-wall anti-de Sitter/quantum chromodynamics (AdS/QCD) model. The framework is extended to f...

A Novel Golf Optimization Algorithm with Paddleboard Childcare and Industry Development–Inspired Strategy for Global Optimization and Practical Engineering Challenges

To address the limitations of the original Golf Optimization Algorithm (GOA) in high-dimensional complex optimization problems, including insufficient population diversity, limited adaptability of search parameters, and late-stage stagnation, this study proposes a Paddleboard-Ins...

Three-dimensional in situ stress reconstruction in deep hard rock by integrated DCDA–DSA inversion of oriented cores

Core-based observables constrain different components of the three-dimensional (3D) in situ stress state in deep hard-rock engineering and therefore require consistent integration. A closed-form DCDA–DSA inversion was developed in which diametrical core deformation analysis (DCDA...
