Rapid jet ejection from PKS 0215+015 coincident with a high-energy neutrino event

Astronomy & Astrophysics
Aims. We present a new neutrino-blazar multiwavelength-flare coincidence, observed in the blazar PKS 0215+015 that showed a strong multiwavelength outburst in positional and temporal coincidence with the IceCube neutrino track alert IC220225A similar to ...

Anomalous Enhancement in MXene‐Based Electrochemical Actuators: Pseudo‐Capacitance‐Induced Multi‐Charge Accumulation in Confined Space

Advanced Science, EarlyView.
We elucidate the electrochemical actuation mechanism of 2D material‐based electrodes within a MXene‐centered framework, linking atomic‐scale surface chemistry to macroscopic performance (see schematic). Mechanistically, the reduction of Ti─O─Ti sites in H2SO4 triggers the accumulation of hydrated ions at confined active sites, resulting in anomalous ...

Evaluating the Validity of Quasi-Static Analysis for Prediction of Vessel Mooring Line Forces

International Journal of Maritime Technology, 2013
Quasi-Static analysis of moored vessels is vastly used for engineering designs, as a substitute to the numerical simulation of dynamic mooring analysis. Yet, the level of validity of the results of quasi-static analysis is a matter of discussion.

Fixed-Point Theorems for Max-Type Rational Contractions in Quasi-b-Metric Spaces

Journal of Mathematics
In this study, we introduce a new class of contractive mappings, termed max-type rational contractions, and analyze their behavior in comparison with the standard contractions widely used in fixed-point theory. Through illustrative examples, we highlight

Inverse Design of Pre‐Strain via a Predictive Electromechanical Model for Enhanced Strain Sensing

Advanced Science, EarlyView.
An analytical electromechanical model rooted in microcrack evolution mechanics is globally calibrated from only eight pre‐strain datasets, enabling prediction of the complete sensing response at untested pre‐strain values within the calibrated design space (R2 > 0.99).

Surface Neuronal‐Like Structuring of High‐Strength CFRP for Enhanced Electromagnetic Interference Shielding

Advanced Science, EarlyView.
This study elucidates the microstructural evolution at the material interface of Ni‐plated plain‐weave carbon fiber fabric following vacuum heat treatment at 500°C–900°C under different current densities, as well as the mechanism underlying the synergistic enhancement of electromagnetic shielding and ductility.

Internal Resonance Mismatch‐Controlled Dissipative Bistability Collapse in Coupled Micromechanical Oscillators

Advanced Science, EarlyView.
This paper reveals internal resonance mismatch‐controlled dissipative bistability collapse in a coupled micromechanical resonator. Tuning δIR changes both internal‐mode amplitude and phase‐dependent feedback. For negative mismatch, Duffing bistability survives.

A high-throughput framework and database for twisted 2D van der Waals bilayers

npj Computational Materials
Twisted two-dimensional van der Waals heterostructures provide a fertile ground for tailoring electronic and structural properties. However, their vast configurational space poses challenges for systematic study. Here, we introduce SAMBA, an open-source,

Interfacial Salinity–Transport Matching in 3D Solar Evaporators: A Framework for Brine‐Stable Solar Interfacial Evaporation

Advanced Science, EarlyView.
A transport‐matching framework is developed to evaluate brine‐stable 3D solar evaporators beyond evaporation rate alone. Using PVA/GNP porous evaporators as a model system, the study shows that stable brine evaporation requires balanced heat generation, liquid replenishment, salt redistribution, and vapor removal rather than maximum dry temperature or ...
