Disintermediation Governance and Complementor Innovation: An Empirical Look at Amazon.com

This study investigates how the platform’s disintermediation governance policy (i.e., the policy that disciplines complementors and consumers circumventing the platform to transact directly) affects complementors’ product innovation and launching strategies. We leverage a change...

Rare Variants May Influence Disease Risk and Clinical Features in Sporadic Late-Onset Chinese Parkinson’s Disease Patients

BackgroundThe heritability in Parkinson’s disease (PD) may be contributed by rare variants (RVs) in candidate genes. Currently there is limited genetic data on Chinese PD patients.ObjectiveWe aim to identify RVs in Chinese PD patients and investigate their relationships with risk...

Managing Perishable Inventory Systems with Positive Lead Times: Inventory Position vs. Projected Inventory Level

We study periodic review perishable inventory systems with a fixed product lifetime, positive replenishment lead times, and a general issuance policy under the average cost criterion. The optimal replenishment policy for such systems is notoriously complex and computationally int...

Optimised murine model of influenza-induced respiratory sepsis for studying acute kidney injury

Abstract Background Viral respiratory sepsis, driven by influenza and COVID-19, is increasingly prominent clinically. However, there is a lack of preclinical models that reliably replicate its associated acute kidney injury (AKI), a major contributor to morbidity and mortality. M...

Robust Public Process in Cultural Planning: Institutionalizing Participation in U.S. Cultural Plans

Problem, research strategy, and findings Cultural planning is widely framed as participatory, yet persistent gaps remain between participatory aspirations and equity-oriented planning and governance. In this study I asked: (1) What constitutes a robust public process in cultural...

Trauma, Transience, and Traversal: Philosophizing on Time Through Su Shi’s Huangzhou-Period Literary Works

Abstract Su Shi’s literary works duing exile in Huangzhou explore temporal experience. To heal the trauma inflicted by the Crow Terrace Poetry Trial, he must understand the temporality of trauma. Trauma is a dialectic of transience. A traumatic event must involve a sudden, unfore...

Comparison and Selection of Network Meta‐Analysis Models for Fitting and Extrapolating Cancer Survival Data

ABSTRACT Aim To assess network meta‐analysis (NMA) model biases under different proportional hazards (PHs) scenarios, compare fitting and extrapolation performance for hazard ratios (HRs) using cancer survival data, identify metrics guiding model selection, and compare extrapolat...

Minimax-Optimal Reward-Agnostic Exploration in Reinforcement Learning

This paper studies reward-agnostic exploration in reinforcement learning (RL)—a scenario where the learner is unaware of the reward functions during the exploration stage—and designs an algorithm that improves over the state of the art. More precisely, consider a finite-horizon i...

Contract-guarded orchestration of the UAV photogrammetry-to-engine handoff: artifact contracts, guarded language-model repair, and a fault-injection benchmark

This paper presents a reliable AI-agent framework for automating the delivery of UAV photogrammetric reconstructions into real-time engines for visualization and digital-twin applications. Conventional workflows often rely on process exit status, allowing semantic errors—such as...

Suppression of Peierls Instability in a Metal−Halide Porous Framework

ABSTRACT Peierls distortion is a lattice instability in low‐dimensional materials driven by electron–phonon coupling, which opens an energy gap at the Fermi level and induces a metal–insulator transition. Suppressing this distortion is crucial for stabilizing metallic and superco...

Transcending the Space‐Bandwidth and Lighting Trade‐Offs: A Programmable Self‐Mixing Interferometry Imager for Cross‐Scale Surface Inspection

ABSTRACT Industrial optical inspection is fundamentally limited by the trade‐off between spatial bandwidth (field‐of‐view vs. resolution) and vulnerability to ambient lighting. This work addresses these challenges by proposing a programmable imager based on amplitude‐modulated la...

Prospective observational study of the impact of early-life feeding on gut microbiome development in caesarean-delivered infants: associations with clinician-confirmed illness

Caesarean section (C-section) born infants acquire a compromised gut microbiome at birth. This prospective observational study investigated the impact of early-life feeding on gut microbiome of C-section born infants and its association with clinician-confirmed, parent-reported i...

P1.042. Utility of a Fenestrated Surgical Drain for the Prevention and Treatment of Esophageal Leak

Abstract Topic Benign Disease: Iatrogenic Esophageal Disease, Perforation and Postsurgical Complications Background Esophageal transmural defects are associated with high morbidity and mortality. Sponge-based endoscopic vacuum therapy (EVT) is effective but costly and requires fr...

Autophagy-regulating bioactive nanoparticle alleviates MASH via gut–liver axis-mediated mitochondria/cAMP/GLP1 pathway

Chronic exposure of the liver to diverse insults can lead to metabolic dysfunction-associated steatohepatitis (MASH), a complex metabolic disorder characterized by hepatic steatosis and inflammation, often accompanied by progressive fibrosis, intestinal barrier dysfunction, and i...

Multi-objective and cross-scale inverse design of temperature-control materials via physics-constrained machine learning

Abstract Temperature-control materials, notably composite phase-change materials (CPCMs), show great potential for the thermal management of next-generation power electronics. However, the synergistic optimization of multiple performance metrics still relies heavily on Edisonian...

The double-decking method for rezūm water vapor therapy in benign prostatic hyperplasia: volumetric, functional, and dosimetric outcomes

Abstract Background Lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) significantly impact quality of life in aging men. Conventional Rezūm water vapor therapy consistently achieves only a modest 25–30% prostate volume reduction, leaving a clinic...

The information content of private information acquisition: evidence from FOIA requests to the SEC

Abstract This study examines whether Freedom of Information Act (FOIA) requests to the Securities and Exchange Commission convey value-relevant information about publicly traded firms and whether sophisticated investors trade on that information. Our empirical analysis reveals he...
