Multi-timescale voltage optimization and control for distribution networks based on regional priority evaluation and deep reinforcement learning

Abstract With the increasing penetration of distributed photovoltaic (PV) generation, energy storage systems, and other flexible resources in distribution networks, conventional voltage regulation methods struggle to address both overvoltage and undervoltage violations and to coo...

One-Pot Cation Exchange−Polymerization Enables FeCoNi-Rich Hollow Magnetic Nanotubes for Boosted Low-Frequency Electromagnetic Wave Absorption

Abstract The rational engineering of magnetic-dielectric absorbers embedded with abundant FeCoNi alloy nanoparticles holds great promise for low-frequency electromagnetic wave (EMW) absorption. However, developing a synthetic approach that simultaneously achieves well-dispersed n...

A telescoping verification of a focal-inversion area invariant

For a proper elliptical billiard with a fixed strictly nested nondegenerate confocal elliptical caustic, the original signed shoelace area times the signed area of the straight polygon obtained by unit inversion of its vertices about either original focus is a positive phase-inde...

Lexical semantic development of high-frequency polysemous words in L2 writing: An LLM-assisted sense-level analysis

A key dimension of L2 writing development is learners’ ability to use words across a wider and more differentiated range of senses, yet this development remains difficult to capture at scale. This study proposes a scalable corpus-based approach to analyzing lexical semantic devel...

Mildly Inhibitory Effects of Sodium Polyanethol Sulfonate and pH on the Growth of Wildtype, lrgAB, and cidAB Mutants of Streptococcus mutans

The lrgAB and cidAB operon encodes for anti-holin-like proteins and holin-like proteins respectively, which are mechanisms of control for endolysin activity in S. mutans. The upregulation of lrgAB genes by chitosan is purported to cause increased cell lysis in Streptococcus mutan...

THE INFLUENCE OF DELAYS AND INJECTION TREATMENTS ON THE DYNAMICS OF TUMOR-IMMUNE SYSTEM

We propose a tumor-CD4+-cytokine-host system with two delays and injection treatments, where two delays denote activation delays for CD4+ T cells and cytokines respectively and host cells compete with tumor cells. First we prove the positivity and boundedness of solutions without...

Retaining snowmelt and precipitation runoff led only partial rewetting but provided cost-effective reduction of greenhouse gas emissions at two boreal peat field sites

Abstract Rewetting is the most effective way to reduce greenhouse gas emissions from agricultural peat soils. This study aimed to improve understanding of the environmental and economic impacts of paludiculture under boreal conditions. Open ditches were blocked using peat dams an...

LAB #4151 NEUTRAL: LEDGER BENCH: Apply filter: Session = NY_OPEN — improves win rate from 32.5% to 38.9% (+6.4pp, n=781 — E8 Intelligence Research

IDEA: Adjustment made to the live model — verify against the backtests: Apply filter: Session = NY_OPEN — improves win rate from 32.5% to 38.9% (+6.4pp, n=781) SAME-WINDOW EFFECT: Applying the NY_OPEN session filter to the live window above would have excluded all trades timestam...

Nonflammable sulfamoyl–carbonate hybrid electrolyte for high-voltage lithium batteries via preemptive passivation

Abstract Achieving high energy density without compromising safety remains a significant challenge for advanced batteries. Nonflammable electrolytes can mitigate fire risk, but poor bulk and interfacial properties of such electrolytes limit their application. Here, a nonflammable...

IMPORTANCE OF LIBRARY RESEARCH SUPPORT SERVICES IN TOP ARWU RANKING UNIVERSITY LIBRARIES

Library Research Support Services (LRSS) is an emerging and popular area in Higher education university libraries, whose increasing importance has been well documented since the early 2010’s, this paper aims to identify the status of LRSS provided in the top ARWU ranking universi...

How Are School Gender Composition and Peer Relationships Associated with Perceived Gender Conflict and Political Interest among South Korean Adolescents?

This study examines how school gender composition and peer relationship orientations are associated with adolescents’ perceptions of gender conflict and political interest. Using nationally representative data from the 2023 Survey on Youth Values in South Korea, we estimate multi...

HIOF • Neutrinos — Paper VI: The Open and the Closed Mouth

Holographic Information Ontological Framework: Neutrinos (HIOF- N) From Propagation to Registration* This is a short, non-technical companion to the 9-paper HIOF- N series (Papers I to IX). It is written for readers in physics or philosophy of science, not for readers already fam...

KUSHONLAR DAVLATI: SIYOSIY, IQTISODIY VA MADANIY TARAQQIYOT

Ushbu maqolada Kushonlar davlatining Markaziy va Janubiy Osiyo tarixidagi siyosiy, iqtisodiy va madaniy ahamiyati yoritiladi. Davlatning shakllanishi, Yuezhi qabilalarining Baqtriyaga ko'chishi, hukmdorlar faoliyati va hududiy kengayishi tarixiy manbalar asosida tahlil qilinadi....

ESMF: Elastic Signature-based Matrix Factorization for Robust Cellular Deconvolution

While bulk RNA sequencing offers clinical practicality through cost-efficiency and scalability for large cohort profiling, it obscures cellular heterogeneity critical for characterizing tissue microenvironment. Conversely, single-cell RNA sequencing (scRNA-seq) resolves cellular...

Invisible schooling: The Independence Ukrainian School case and the paradoxes of forced migration in Poland

This article examines the Independence Ukrainian School, a refugee-led educational initiative established in Poland after Russia’s full-scale invasion of Ukraine in 2022. Created by displaced Ukrainian teachers to ensure educational continuity through the Ukrainian curriculum, th...

Restricted Partitions

This paper introduces Sivanendran’s Restricted Partition Function (SRPF), a novel framework for constructing and enumerating restricted partitions of natural numbers. Unlike contemporary approaches, SRPF relies on simple floor functions and integer division, making it computation...

Non-Word-Representable Single-Triangle Graphs with Word-Representable Line Graphs

For every odd integer m >= 5, let G_m be the Mycielski graph of the cycle C_m with an additional edge joining the shadow copies of two adjacent cycle vertices. We prove that G_m is connected, has exactly one triangle, and is a minimal non-word-representable graph under induced-su...

Aramid Colloidal Aerogels: Architecting Nanofibers via Dynamic Sol–Gel Transition for Multifunctional Applications

Conspectus Aerogels have long captivated materials scientists with their extreme properties─ultralow density, high porosity, and enormous specific surface area. Yet for nearly a century, their fabrication has remained trapped in a static paradigm: the sol–gel transition of small-...

Religious information repertoires in Switzerland’s hybrid information environment: asymmetric associations with trust and reputation

In hybrid media environments, public understanding emerges from patterned combinations of legacy news media, digital platforms, and interpersonal communication. Rather than relying on single channels, individuals assemble repertoires of mediated sources, interpersonal encounters,...
