Near-ideal plug-flow enables stage separation during dry anaerobic digestion of biowaste in a rotating drum fermenter

Conventional designs of anaerobic plug-flow reactors frequently exhibit stagnant zones and pronounced short-circuiting, undermining plug-flow behavior and reliable biowaste pasteurization. Ideal plug-flow conditions could, in contrast, enable a spatial separation of metabolic sta...

The Transmission Mechanism of Monetary Expansion to Corporate Distress: A Case Study of Carvana Co. Under the Post-Pandemic Inflationary Regime

This academic research paper constructs a mathematically rigorous, structurally integrated micro-macro econometric framework designed to isolate and quantify the exact transmission mechanisms through which systemic macroeconomic monetary shocks propagate into corporate capital st...

When trust is not enough: buyer orchestration modes and innovation in coopetitive automotive supply networks

Purpose This study examines how buyer orchestration modes shape knowledge-sharing dynamics and innovation outcomes among competing suppliers in multi-tier automotive supply networks. While prior coopetition research emphasizes trust and voluntary collaboration as drivers of innov...

Generative AI for Hospital Cybersecurity: A Framework for Evaluating Large Language Models for Planning, Threat Detection, and Incident Response

The increasing digitization of healthcare records and growing reliance on interconnected systems have increased hospitals’ exposure to cyber threats, including ransomware, brute-force attacks, and Structured Query Language (SQL) injection. Traditional cybersecurity approaches alo...

Empathic Logic Model (ELM): A Cognitive-Interactional Coherence Framework for Regulating Interpretive Instability

Human meaning-making under uncertainty frequently defaults to premature interpretive closure (PIC). Under emotional activation or cognitive bias, this generates disproportionate emotional reactivity and relational tension. To regulate this instability, the Empathic Logic Model (E...

Liquid-Phase Laser Micro-Dimple Texturing of YG8 Cemented Carbide Tools: Optimization, Wear Mechanism, and Cutting Performance

Cemented carbide is extensively applied in cutting tools. Surface laser micro-texturing alleviates tool surface wear and boosts cutting performance. This work adopts response surface methodology to investigate circular micro-texture parameters (diameter, spacing, offset) of YG8 c...

Which Constant Is Responsible? Dominator Analysis of Classical Dependence in Mathlib

61.2% of Mathlib's theorems depend on Classical.choice. Asking which constant is responsible for that dependence is a different question from asking which constants a proof touches, and the two answers differ by a factor of 58 on the first case examined: 116,766 theorems reach th...

Effects of Hydrochars Derived from Woody Residues on Soil Enzyme Activities and Plant Response

The growing need for biomass waste recycling has led to increased interest in hydrothermal carbonization, which produces hydrochar as a by-product. This carbonaceous material can be applied in agriculture; however, its role in soil health is still not fully understood. Data on th...

Culturable Opportunistic Bacteria and Antimicrobial Susceptibility Patterns in Canine Periodontal Pockets: A Pilot Study

Canine periodontitis is one of the most prevalent chronic diseases for dogs over two years of age. Periodontal pockets may serve as a reservoir for opportunistic bacteria including Pasteurella stomatis, Neisseria animaloris, and Streptococcus canis; however, data on their antimic...

Comprehensive Design and Structural Verification of a Tubular Steel Metal–Hydride Storage Vessel for Hydrogen Separation and Storage

Hydrogen storage and separation remain major technical challenges limiting the broader implementation of hydrogen-based energy systems. Metal–hydride alloys offer a promising solution because they enable reversible hydrogen storage within their crystal structure and can selective...

Impacts of Cold Waves and Urban Heat Islands on Heating Energy Consumption Differences Across Intra-Local Climate Zones

Most studies have explored the impact of different types of local climate zones (LCZs) on energy consumption, but few have examined climate differences within intra-local climate zones (intra-LCZs) and the impact of cold waves (CW) on energy consumption. This study conducted a 15...

Effectiveness of web-based cognitive behavioral therapy for perfectionism in reducing symptoms of social anxiety disorder

Abstract This study examined the effectiveness of web-based cognitive behavioral therapy for perfectionism (WCBT-P) in reducing symptoms of social anxiety disorder (SAD) and indices of perfectionism in individuals with SAD. A total of 40 participants diagnosed with SAD and malada...

Key innovation triggers adaptive radiation of the genus Medicago

Reconstruction of a robust phylogeny of Medicago using genome-scale nuclear data from the Angiosperms353 probe set sheds light on the origin of the genus and provides evidence that pod morphological traits acted as key innovations, playing a central role in the adaptive radiation...

Virtuelle Welten & Games, Vol. 3: Fulbright Scholars of the Media Department at Offenburg University

Internationalization is one of the strategic core responsibilities of universities. Each semester, Offenburg University welcomes many dozens of exchange students and international first-year students. In total, approximately 14% of the university’s 3,700 students belong to the gr...

LoRA Fine-Tuning Enables Controllable Mathematical Reasoning in Small Language Models: A Gating Pipeline on Qwen3.5-0.8B

We design a gating pipeline for LoRA fine-tuning of Qwen3.5-0.8B, a 24-layer hybrid of GatedDeltaNet and Full Attention, executed entirely on CPU. The pipeline runs three ablations: layer ablation selects full-module joint fine-tuning over single-module configurations; data curri...

Spot melting in electron beam powder bed fusion: influence of the melt pool shape on microstructure and texture

Abstract Reliable microstructure control remains a major challenge in electron beam powder bed fusion, particularly for Ni-based superalloys such as IN718, where large columnar grains with a strong $$\langle 100\rangle $$ texture cause highly anisotropic behavior, often limiting...

Political Belonging in the Ghana-Togo Borderlands: Citizenship and the Vote at the Margins of the State

Nathalie Raunet’s Political Belonging in the Ghana-Togo Borderlands examines the construction of territorial political communities through a study of the Ewe, an ethnic group straddling the Ghana-T...

How retailer prestige drives sales performance and turnover: the mediating role of organizational identification and moderating role of professional identification

Purpose Retailer organizational prestige is defined as employees' own beliefs and perceptions about how individuals external to the organization judge and evaluate the status and prestige of their firm. Although researchers and professionals recognize that retailer organizational...

Geometry-Informed Adaptive Time-Series Fusion of ADS-B Sensor Data for Short-Term Aircraft Trajectory Prediction

Automatic Dependent Surveillance-Broadcast (ADS-B) systems provide continuous aircraft position reports for aviation surveillance and short-term trajectory prediction. However, many data-driven predictors directly model the longitude, latitude, and altitude contained in ADS-B mes...
