Molecular-dynamics simulations of void formation in Si wafer during stealth dicing processes

Stealth dicing is a process used in semiconductor manufacturing to cut wafers into individual chips. It involves focusing a laser beam inside a silicon wafer to produce a modified layer, which is then subjected to an external force. The modified layer consists of regions with hig...

Interface engineered perpendicular magnetic anisotropy-controlled propagation of magnetic domain

We report the impact of ferromagnetic layer thickness and stack configuration on the magnetic properties, perpendicular magnetic anisotropy (PMA), modified magnetization switching mechanisms, and creep regime domain wall (DW) dynamics, including their propagation velocity, in a P...

Benchmarking the safety of large language models for robotic health attendant control

Abstract Large language models (LLMs) are increasingly considered for deployment as the control component of robotic health attendants (RHAs), yet their safety in this context remains poorly characterized. We introduce a dataset of 270 harmful instructions spanning nine prohibite...

Protein–protein interaction network-based evaluation of lung cancer relevance and hub gene identification from in vitro crocidolite exposure signatures

Abstract Objectives This study evaluated whether a protein–protein interaction (PPI) network-based approach can link in vitro exposure-induced gene expression signatures to human disease modules. Methods Crocidolite, a well-established lung carcinogen, was used as a model of inha...

Adaptive Conformal Prediction with Foundation Models

Adaptive conformal prediction methods adjust prediction intervals online to maintain valid coverage under distribution shift. We study how predictor quality interacts with method effectiveness. We evaluate 21 conformal prediction methods and variants, including Conformal PID, SPC...

Imperfect Simulator Interventions: AI for Science

Computational simulators are increasingly used as surrogates for interventional experiments in causal discovery, but real-world simulators inevitably introduce variable omission, intervention noise, and structural misspecification. We show that a two-layer strategy---separating s...

Where Individual-Effect Information Survives: A Diagnostic Ladder for World Models

World models are widely used for planning and control, but it remains unclear whether they can answer counterfactual questions of the form ``what would have happened to this individual under a different action.'' Such a question sits at the third rung of Pearl's ladder and requir...

Sub-linear Power-Law Scaling of Information Processing Capacity in Noisy Physical Reservoirs

How does the computational capacity of a physical reservoir scale with the number of devices? This paper quantifies the dependence of information processing capacity (IPC) on device count under device noise identified from hardware measurements and reports three findings. (1)~IPC...

Bottom-Up Model Suggesting Membrane Localization of Heme Oxygenase-1 Contributes to Heme Selection for Degradation

Abstract Heme functions as a prosthetic group in numerous hemoproteins, whereas a fraction of intracellular heme is not tightly bound to proteins or membranes and can readily dissociate; this labile heme participates in the regulation of diverse cellular processes. Heme has pro-o...

Odd-Parity Crystalline Electric Field and Multipoles in Icosahedral Quasicrystal and Approximant: Magnetic Toroidal and Electric Dipoles in Ce-Based Systems

Quasicrystals (QCs) lack periodic arrangement of atoms but possess unique structural order distinct from periodic crystals and random systems. The electronic property is far from complete understanding. Here we have formulated not only even-parity but also odd-parity crystalline...

Descriptors to Dynamics: A Materials and Device Perspective on in‐Materio Physical Reservoir Computing for Neuromorphic Edge Intelligence

Reservoir computing is attractive for edge intelligence because it not only reduces training overhead but also turns transient material physics into computation. In in-materio systems, memory, nonlinearity, separability, and efficiency are not added later at the circuit level; th...

GDA-Pred: Generative AI-Driven Data Augmentation for Improved Prediction of IL-6 and IL-13-Inducing Peptides

Abstract The identification of interleukin-6 (IL-6) and interleukin-13 (IL-13) inducing peptides is crucial for accelerating drug discovery targeting cancer, immune disorders, and infectious diseases. However, experimental screening methods remain time-consuming and costly. To ad...

Comparative Analysis of Ion and Electron Contributions to Ionospheric Ionization at Auroral and Subauroral Latitudes

Abstract Electron and proton precipitation into the nightside ionosphere is a key process in magnetosphere–ionosphere coupling. Although auroral electron precipitation at –10 keV is traditionally considered the main driver of auroral emissions, recent studies show that keV electr...
