Atomic‐Level CuOx‐CoOx‐Pd Interfacial Engineering Enables Hierarchical Synergy for High‐Efficiency ORR Pathways and Boosted Power Output in Alkaline Fuel Cells

open access: yesAdvanced Science, EarlyView.
Atomically dispersed CuOx (CPCu‐1) forms isolated Cu–Ov sites that enable defect‐mediated O2 activation and fast electron/proton transfer via interfacial synergy. In contrast, thick CuOx clusters (CPCu‐10) promote a surface‐adsorption‐controlled pathway with intermediate accumulation, highlighting a mechanism switch from interfacial activation to ...

Confined compression tests : Outlining the failure envelope of columnar sea ice

open access: yes, 1986
A series of confined compression tests has been performed on columnar sea ice over a range of nominal strain rates of 10\u207b\u2075 to 10\u207b\ub3 s\u207b\ub9 at a temperature of -2\ub0C.

AI‐Physics‐Experiment Trinity for Integrated Protein Dynamics Modeling

open access: yesAdvanced Science, EarlyView.
This review unites experiments, physics‐based simulations, and AI as a synergistic triad for protein dynamics modeling. It highlights integrative strategies, resolves sampling and forcefield bottlenecks, and outlines challenges and future directions for accurate, interpretable conformational ensemble prediction.

Detection and Diagnosis of Rolling Element Bearing Faults Using Time Encoded Signal Processing and Recognition

open access: yes
This thesis presents a systematic study of using TESPAR (Time Encoded Signal Processing and Recognition), which presently is in use as an effective tool for speech recognition and shows great advantages in computational demands and accuracy, to develop a

The Progressive Development and Post-failure Behaviour of Deep-seated Landslide Complexes [PDF]

open access: yes, 2011
The concept of progressive shear surface development remains to be fully understood. This study aims to investigate the mechanisms of progressive shear surface development to failure, and the subsequent post-failure behaviour, of deep-seated landslide ...

Assessment of the response envelope of reinforced concrete members with different failure modes

open access: yes, 2021
The expected lateral response of reinforced concrete (RC) elements strongly depends on their failure mode. Code-conforming RC members are supposed to exhibit a flexural (F) ductile failure, with complete exploitation of their post-peak displacement ...

Placental Site Trophoblastic Tumor Acquires Immune Functions by Incorporating Host Maternal Genes

open access: yesAdvanced Science, EarlyView.
PSTT cells, through cell fusion with B cells, incorporate abundant non‐inherited maternal genes that are detectable by DNIMA. These hybrid cells acquire immunotherapy‐resistant genetic changes and increase the expression of B cell‐derived immune‐related molecules such as Ig, HLA, LILRB, SIGLEC10, and so on, creating an immunotolerant environment around

Failure Envelope of Asphalt and Asphaltic Mixture at Low Temperature

open access: yes, 1994
本研究は種々のアスファルトを用い,アスファルトとそのアスファルトを用いたアフスァルト混合物について低温領域において2種の曲げ試験を実施し,これを引張の破壊状態に換算し,破壊包絡線の形状や位置およびそれらの関係について検討した。実験の結果,各種アスファルトの低温領域における破壊包絡線の形状は大きく三つのタイプに分類され,アスファルト混合物の破壊包絡線の形状は使用したアスファルトのそれとほぼ同一であり,針入度には依存しないこと ...

Stress Invariants and Invariants of the Failure Envelope as a Quadric Surface: Their Significances in the Formulation of a Rational Failure Criterion

open access: yes
When stress invariants up to the second order are employed to construct failure criterion for brittle materials, it involves three independent terms and therefore there are three coefficients to be determined.
