The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

Contributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

Reweighting Scheme for the Calculation of Grand‐Canonical Expectation Values in Quantum Monte Carlo Simulations With a Fermion Sign Problem

Contributions to Plasma Physics, EarlyView.
ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator

Laser &Photonics Reviews, EarlyView.
This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.

Rigorous Electromagnetic Quasinormal‐Mode Method Made Easy for Users

Laser &Photonics Reviews, EarlyView.
We present a method that combines numerical techniques with accurate approximations to enable simple and ultrafast computations of the scattered field based on quasinormal modes expansions. The method is made available in the open‐source package MANlite implemented within COMSOL.

Integrated LEO Constellation and In‐Cabin Distribution System for Continuous Aircraft 5G Connectivity

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency (>$$ > $$ 500 ms) and inadequate coverage at high ...

Image and video analysis using graph neural network for Internet of Medical Things and computer vision applications

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Graph neural networks (GNNs) have revolutionised the processing of information by facilitating the transmission of messages between graph nodes. Graph neural networks operate on graph‐structured data, which makes them suitable for a wide variety of computer vision problems, such as link prediction, node classification, and graph classification.

Climate exposure drives firm political behavior: Evidence from earnings calls and lobbying data

American Journal of Political Science, EarlyView.
Abstract When and how do firms engage in climate politics? We argue that regulatory concerns, business opportunities, and physical risks activate policy preferences and lobbying efforts. We measure firm‐level exposure to opportunity, regulatory, and physical aspects of climate change based on discussion in quarterly earnings call transcripts for 11,705

Intermediate Effects Between Experiences of Violence at Home, School, Street, TV and Child‐to‐Parent Violence

Child &Family Social Work, EarlyView.
ABSTRACT Exposure to violence is an adverse experience related to child‐to‐parent violence. The objectives were to examine differences in child‐to‐parent violence according to the sex and age of the children and to analyse the mediating role of reactive and instrumental reasons between exposure to direct and indirect violence across different contexts ...

The specifics of non‐routine task changes: A granular approach

Contemporary Economic Policy, EarlyView.
Abstract This paper estimates granular specific non‐routine tasks and examines employment reallocation across those tasks in the United States. Employment shifts into decision‐making, technology, and information‐related tasks account for 90% of high‐wage employment growth.

1162. Symphyotrichum oolentangiense (Riddell) G.L. Nesom

Curtis's Botanical Magazine, EarlyView.
Summary Symphyotrichum oolentangiense (Riddell) G.L. Nesom (Compositae: Astereae: Symphyotrichinae) is described and illustrated. A very brief biographical note of John Leonard Riddell, the collector and author of the species, is offered. Notes are provided for the species' cultivation, propagation, likely pests and diseases, and availability.
