This work presents a triaxially deformed photonic crystal cavity on the SOI substrate, enabling the localization and resonating of photons via pseudomagnetic fields. Through coupling with Si waveguides and leveraging the thermo‐optic effect, electrically tunable pseudo‐magnetism‐induced optical resonances can be achieved in the photonic integrated ...

Locally Markov Walks on Finite Graphs
ABSTRACT Locally Markov walks are natural generalizations of classical Markov chains, where instead of a particle moving independently of the past, it decides where to move next depending on the last action performed at the current location. We introduce the concept of locally Markov walks and we describe their stationary distribution and recurrent ...

Cicada as a food for mammals: a global review and implications for mammal behaviour and populations
Cicadas (Hemiptera: Cicadidae) are among the most important insect prey for many vertebrate predators, including birds and mammals, owing to their large size and high nutritional value. Although the ecological roles of cicadas as prey for birds have been well documented, the interactions between mammals and cicadas are relatively unknown.

This paper proposes an eXtreme gradient boosting tree (XGBoost)–long short‐term memory (LSTM) fusion model using traffic big data, integrating temporal, meteorological, and spatial features. First, the XGBoost models historical congestion ratios and associated features for each region, generating preliminary predictions and extracting regional residual

FaXToR: the hard X‐ray micro‐tomography beamline at the Spanish synchrotron ALBA
The Spanish synchrotron ALBA has recently inaugurated BL31‐FaXToR, a beamline for hard X‐ray micro‐tomography. The design, performance and scientific program of the beamline are described.FaXToR is the first hard X‐ray imaging beamline built and commissioned at the Spanish synchrotron light source ALBA, and therefore the start of user operation marks ...

Properties, mechanisms, and perspectives of ultrafast laser modifications in silicate glass volume
Abstract Ultrafast laser irradiation of glass enables highly localized structural transformations within the material's bulk, unlocking diverse applications in photonics, data storage, and microfabrication. Here, we provide a concise yet comprehensive overview of the main types of femtosecond laser‐induced modifications in silica‐based glasses (Types I,

This study investigates a discrete‐time predator–prey model that includes both prey refuge and memory effects. The research identifies the conditions under which fixed points exist and remain stable. A key focus is placed on analyzing different types of bifurcation—such as period doubling (PD), Neimark–Sacker (NS), and strong resonances (1 : 2, 1 : 3 ...
