Network Topology Obfuscation: Challenges, Solutions, and Comparisons

Attackers infer the network topology to locate critical components and to plan cost-effective attacks with high success rates. Network topology obfuscation (NTO) counters this by exposing a well-designed fake topology that misleads the inference and raises the cost of attack. Exi...

Hierarchical Organization Modulates Transient Thermal Relaxation Dynamics in Chitinous Cuticles from Marine and Terrestrial Organisms

Abstract Chitinous cuticles are hierarchical biological composites in which the molecular organization spans multiple structural length scales. Although the relationships between chitin chemistry and mechanical performance have been extensively investigated, the structural factor...

Through an anxious lens: The roles of adolescents' anxiety symptoms in conditioning the relational consequences of parental responses to negative emotions through shaping adolescents' appraisals of parental responses

Abstract Grounded in the cognitive‐affective models of anxiety and the emotion socialization theory, the present study aimed to examine how adolescents' anxiety symptoms may moderate the associations of parental earlier responses to adolescents' negative emotions with the subsequ...

GaSb–TFLN Hybrid Integrated Pockels Laser for Ultrafast Spectroscopy in the 2 μm Waveband

Abstract High-speed wavelength-tunable lasers in the 2 μm waveband are important for laser spectroscopy, optical communication, and frequency-modulated continuous-wave LiDAR. Here, we demonstrate a hybrid integrated Pockels laser that combines a GaSb reflective semiconductor opti...

Safeguarding global terrestrial vertebrate species from future sea-level rise

Sea-level rise (SLR) threatens terrestrial biodiversity, yet its spatiotemporal and species-specific impacts remain unclear. Integrating relative SLR projections across five Shared Socioeconomic Pathways (SSPs) with Area of Habitat (AOH) maps for 34,120 terrestrial vertebrate spe...

Three-dimensional density and air–rock interface reconstruction with muography: Application to the TianQin tunnel

Muography is a non-invasive imaging technique that uses cosmic-ray muons, commonly divided into transmission (absorption) and scattering muography. For transmission muography, the inversion algorithm critically determines reconstruction quality. However, widely used schemes may p...

AI-assisted discovery of an ABCA1/ABCG1 activator for restoring mitophagy and mitigating Alzheimer’s pathology

Abstract Defective mitophagy is a key pathological risk of Alzheimer’s disease (AD), yet available pharmacological agents capable of restoring mitophagy remain clinically limited, largely due to the lack of tools for drug screening and target identification. To address this, we i...

Sex‐Specific Digital Phenotyping of Lower Urinary Tract Symptoms: A Cross‐Sectional Study of 1586 Adults From 35 Centers in China

ABSTRACT Background and Purpose Lower urinary tract symptoms (LUTS) represent a complex clinical syndrome with significant sexual dimorphism. Traditional “one‐size‐fits‐all” management often overlooks intra‐sex phenotypic heterogeneity. This study utilized unsupervised machine le...

Ultrasound-Induced Mechanoluminescence: From Remote Activation to Emerging Photonic and Biomedical Applications

Abstract Mechanoluminescence (ML) has traditionally been understood as a mechanically induced light emission phenomenon activated by direct contact stimuli such as fracture, deformation, or friction. The emergence of ultrasound (US) as a remote, noncontact mechanical excitation s...

Lattice Boltzmann Modeling of Droplet Impact on a Superhydrophobic Ridge

ABSTRACT The impact dynamics of droplets on a single rectangular superhydrophobic ridge are systematically investigated using the lattice Boltzmann method. The effects of ridge width, droplet deviation, and Weber number on droplet deformation and breakup are examined through exte...

Integrated retrieval of ocean surface wind and current fields from single-geometry SAR observations through a physically constrained Bayesian framework

Ocean surface winds and currents are coupled through air–sea interaction but are commonly retrieved independently from spaceborne synthetic aperture radar (SAR). For operational single-geometry SAR, simultaneous wind–current retrieval is underdetermined and remains reliant on bac...

A pH-Responsive Charge-Reversal Nanoplatform for Combined Chemophotothermal Therapy of Oral Cancer

Abstract The global incidence of oral cancer has risen rapidly at progressively younger ages due to the impact of unhealthy lifestyle habits. Therefore, there is an urgent need to develop novel oral cancer treatments. Combination therapy with chemotherapy and photothermal therapy...

Partially hyperbolic geodesic flow via conformal deformation

This paper presents a new construction of non-Anosov partially hyperbolic geodesic flows. Our construction is closely related to the construction presented in [10] , the novelty is the use of conformal deformations to produce the examples. Some of the necessary conditions appear...

Improved estimation of net ecosystem CO 2 exchange over North America using LSTM-based flux upscaling (2001–2021)

Accurate estimation of regional-scale terrestrial carbon budgets is of great importance but remains challenging. With particular advantages, the Long Short-Term Memory (LSTM) network method shows potential for improving regional carbon budget upscaling estimations. Here, using LS...

Poly(propylene carbonate- co -thioether- co -ether) Terpolymer and Its Application as a Solid-State Electrolyte

Abstract Sulfur-containing polymers, especially those with sulfur in the main chain, have attracted significant interest owing to their diverse structures and unique properties, making them promising candidates for solid-state electrolytes. However, their controllable synthesis i...

Ultrasensitive Electrochemiluminescence Aptasensor With DNA Nanotetrahedron Amplification for Multilevel Detection of cTnI From Cells to Patients

ABSTRACT Accurate detection of myocardial injury (MI) biomarkers for assessing anticancer drug‐induced cardiotoxicity has long been constrained by insufficient capture efficiency and limited assay sensitivity. To address this challenge, we developed an electrochemiluminescence (E...

The impact of perceived fairness on consumers’ willingness to pay for water quality improvements: evidence from China

Financing drinking water improvements in low tariff regimes requires price increases, yet affordability alone cannot ensure public acceptance. In a survey experiment with 1027 urban Chinese residents, perceived fairness is associated with 0.58–0.84 RMB/m3 higher WTP for cleaner r...

Monitoring neutrophil extracellular traps (NETs) related citrullinated histone H3: a novel biomarker of recurrence and metastasis in nasopharyngeal carcinoma

Abstract Objectives Blood-based biomarkers play a crucial role in tumor monitoring. However, for nasopharyngeal carcinoma with recurrence or metastasis (R/M-NPC), there is a notable scarcity of sensitive markers. Citrullinated histone H3 (H3Cit), a key marker of neutrophil extrac...
