Admittance spectroscopy of organic-silicon heterojunction structures fabricated with ultrasound assistance

The development of methods for controlled modification of silicon–polymer structures is essential for advancing next-generation solar cells. This study investigates the influence of ultrasound treatment (UST) applied during fabrication on the electrical properties of Ag/PEDOT:PSS...

Policy-Constrained Query Placement at the Edge: A Catalog Architecture, Complexity Analysis, and Latency Trade-Offs

Edge databases must coordinate replica freshness, consistency requirements, and governance restrictions despite intermittent connectivity. This study specifies an Edge-Aware Database Management System (EA-DBMS) architecture centered on the Policy-Aware Distributed Edge Catalog (P...

Microwave properties of PVC-based composite films with yttrium iron garnet and carbon fillers

Thin poly(vinyl chloride)-based composite films containing 20 wt.% Y3Fe5O12 and 10 wt.% carbon filler exhibit a pronounced filler-dependent electromagnetic response in the Ka-band. Activated carbon, MWCNTs, graphene nanoplatelets, carbon nanoparticles, and carbon black were chara...

Quasi-maximum likelihood estimation for scalar SDEs driven by stable Lévy noise

We develop a computational quasi-maximum likelihood procedure for drift-parameter estimation in discretely observed stochastic differential equations driven by α-stable Lévy noise. The transition density is evaluated numerically through a Malliavin representation and Monte Carlo...

OncoTagger: a reproducible abstract-level landscape of open-access AI-oncology articles in Web of Science

Abstract AI-oncology evidence is expanding too quickly for static manual surveillance. We developed OncoTagger, a rule-based abstract-level evidence-surveillance pipeline, and applied it to an English-language, open-access article corpus indexed in the Web of Science Core Collect...

Regulation of the Expression of Inflammation and Extracellular Matrix Genes during the Healing of Purulent-Necrotic Wounds under the Influence of Biologically Active Preparations

Abstract The problem of wound treatment, in particular purulent-necrotic, remains one of the most urgent, especially in the conditions of a full-scale war in Ukraine. One of the promising areas of therapy for such wounds is the use of proteolytic enzymes for their enzymatic clean...

Statistical analysis of court documents based on the developed taxonomy

This presentation explores the earnings within the realization of the Legal Case Law Analytics and Modeling (LCAM) project, which applies AI technologies and statistical modeling to large-scale civil judicial data in Ukraine. It details the development, structural transformation,...

From Nazism to “Denazification”: The Transformation of a Historical Concept in Russian War Propaganda

Abstract This article examines how the historical concept of Nazism has been transformed into a propaganda narrative within Russian state media discourse. Since the full-scale invasion of Ukraine in 2022, Russian leaders have repeatedly justified military action through the langu...

Fate of post-blast residue in soils from an armed conflict zone determined by magnetic, microbiological, and ecotoxicological assessments

Weapon detonations generate substantial quantities of post-blast residue (PBR), which contributes iron-rich particles to soils. After deposition, these residues undergo redox transformations that produce bioavailable iron compounds, potentially increasing phytotoxic risks to agri...

Structure based discovery of antipsychotic-like TAAR1 agonists

Abstract Schizophrenia is a severe mental illness whose current treatments primarily target dopamine and serotonin receptors. These drugs often cause side effects and vary in effectiveness across patients. The trace amine-associated receptor 1 (TAAR1), which modulates monoamine s...

A Unified Neural Framework for Punctuation and Capitalization Restoration Using XLM-RoBERTa–BiLSTM

Accurate punctuation and capitalization are essential for the readability, interpretability, and structural coherence of machine-generated text. Their absence is particularly problematic in automatic speech recognition outputs and other forms of unstructured text, where missing p...

Association of plasma oxalate with computed tomography–derived stone characteristics in calcium oxalate nephrolithiasis

Calcium oxalate (CaOx) nephrolithiasis shows wide variation in stone size and density that is not fully explained by urinary risk factors. Plasma oxalate (POx) reflects systemic oxalate balance, but its relationship with imaging-defined stone characteristics has not been studied....

Pushing the boundaries of virtual screening scale of combinatorial spaces with the V-SYNTHES approach

Computational screening of giga-scale chemical spaces opens a cost-effective path to high-quality hit identification, providing entry points for drug discovery. As these on-demand spaces grow and successful applications multiply, rigorous blind benchmarks like CACHE Challenges pr...

On a Hidden Supersymmetry of Cosmological Billiards

In the Belinski-Khalatnikov-Lifshitz cosmological models with an oscillatory approximation to singularity, the tracks of cosmological billiards (whatever they are) are realized in the Weyl chambers of the hyperbolic Lie algebras. The latter were classified by Li Wang Lai; their s...

Scalable AnnulationApproach to Functionalized 1-Azabicycloalkanes

Abstract A unified, scalable annulation strategy toward functionalized 1-azabicycloalkanes is presented, enabling the efficient preparation of 1-azabicyclo[3.2.0]heptane, pyrrolizidine, indolizidine, and quinolizidine cores. The approach relies on a reproducible and scalable α-al...

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...

Application of the Hirshfeld Atom Refinement to Determine the Spin State of the Novel Fe(III) Schiff Base Complex

The novel complex [FeIII(HL)(L)]·2dmf (1) was successfully synthesized by reacting iron chloride with dimethylformamide solution of the Schiff base ligand (H2L). The ligand was prepared in situ through the condensation of 5-bromo-salicylaldehyde and benzhydrazide. The compound 1...

Mechanisms of Psychological Adaptation of Citizens to Post-War Reality and Overcoming Traumatic Experience

The aim of this study was to determine the effectiveness of psychological support programmes and initiatives in facilitating citizens’ adaptation to post-war reality and in reducing the consequences of traumatic experience. The methodology included theoretical analysis, statistic...

C60 Fullerene Promotes Restoration of Kidney Function After Chronic Glyphosate Intoxication

Glyphosate is one of the most widely used herbicides in modern agriculture. Toxicological studies have demonstrated that chronic glyphosate exposure is associated with the development of systemic disorders, particularly renal injury. Therefore, the search for effective therapeuti...
