Reconfiguration of active medium- and low-voltage distribution networks based on multi-agent systems and mutual support capacity

Reducing power losses and preventing voltage instability remain key concerns in electrical distribution networks (DNs). These challenges are often addressed through reconfiguration of the network and the integration of distributed generation (DG) resources. In this study, a multi...

Storm surge dynamics in the northern Adriatic Sea: comparing AI emulators with high-resolution numerical simulations

Abstract. Accurate storm surge forecasting is vital for protecting coastal regions, particularly in the northern Adriatic Sea where sea-level rise and increasingly severe storm events pose growing risks. Machine Learning (ML) approaches offer compelling speed and flexibility, yet...

Simplified modeling of the impact of lithospheric-scale geological processes on thermal histories and low-temperature thermochronometers

Abstract. Many geological processes influence or perturb the thermal state of the lithosphere. This presents a challenge for relating thermal history data modeled from thermochronometers such as apatite and zircon fission-track and (U-Th)/He dating to geological evolution, a prim...

Robust topology optimization of electric machines using topological derivatives

Abstract Designing high-performance electric machines that maintain their efficiency and reliability under uncertain material and operating conditions is crucial for industrial applications. In this paper, we present a novel framework for robust topology optimization with partial...

Thermodynamic properties of polyurethane foam concrete in complex environments

To study the heat storage performance of polyurethane foam concrete (PFC) when incorporating solid-solid phase change materials in complex environments. The thermal characteristics and heat storage performance of different density PFCs under carbonation and freeze-thaw cycles wer...

The Advancement of Brillouin Light Scattering with the Assistance of Nanoplasmonic Structures. Enhancement and Amplification

Abstract Brillouin light scattering (BLS) is a key technique in studying magnonic systems, though its detection capabilities are often constrained by low signal-to-noise ratios. While nanoplasmonic systems can enhance BLS through near-field effects, we propose a novel approach fo...

High-accuracy electromagnetic analysis method for differential circuits with discontinuities

<title>Abstract</title> This paper presents a high-accuracy electromagnetic (EM) analysis method for differential circuits that accurately considers the effects of structural discontinuities. Discontinuities at interfaces between components—such as MOSFETs with ground planes and...

Regional CO 2 and CH 4 inversion system using WRF-Chem (v4.4)/DART (v9.8.0) and continuous high-precision observations over the Korean Peninsula

Abstract. Quantifying greenhouse gas (GHG) emissions over complex terrain remains a significant challenge for conventional inversion systems due to the high sensitivity of tracer transport to surface heterogeneity. We develop a high-resolution dual-species GHG top-down inversion...

Age Cohort Patterns of Socioeconomic Inequalities in High-Risk Body Mass Index (BMI) and Waist to Hip Ratio (WHR) Composite: Findings from Nationally Representative Survey

<title>Abstract</title> Background Obesity is a growing global health challenge, with central adiposity posing particularly high cardiometabolic risk. In low- and middle-income countries (LMICs) like India, the coexistence of undernutrition and obesity reflects a double burden of...

Assessment of masticatory muscle activity and mandibular border movement in skeletal class II malocclusion adolescents with mandibular retrognathia

<title>Abstract</title> Objective To investigate masticatory muscle activity and mandibular border movement in adolescents with skeletal class II malocclusion and mandibular retrognathia and explore the influence of mandibular retrognathia on masticatory system function. Methods...

Efficient protocol to estimate the Quantum Fisher Information Matrix for commuting-block circuits

Abstract The Quantum Fisher Information Matrix (QFIM) quantifies how sensitive parameterized quantum states are to changes in their parameters. Recently, it has been used to improve variational quantum algorithm optimization through geometry-aware techniques. However, estimating...

Maternal sensitivity supports infant sleep: evidence from two longitudinal prospective cohorts on maternal childhood maltreatment, maternal sensitivity, and infant sleep

Maternal childhood maltreatment (CM) has been linked to adverse outcomes in the next generation, including infant sleep, which is crucial for healthy development. This study examined whether maternal sensitivity buffered these effects in 101 German and 117 U.S. mother-infant dyad...

Single‐Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum

B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue-specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome mai...

Digital quantum simulation of many-body localization crossover in a disordered kicked Ising model

Simulating nonequilibrium dynamics of quantum many-body systems is one of the most promising applications of quantum computers. However, a faithful digital quantum simulation of the Hamiltonian evolution is very challenging in the present noisy quantum devices. Instead, nonequili...
