Comparative Lipophilic Phytochemical Profiling and Bioactivity Assessment of Different Organs of Mahonia aquifolium (Pursh) Nutt.: Integrated Analysis of n-Hexane Extracts, Essential Oils and Fatty Acids

Mahonia aquifolium (Pursh) Nutt. is a medicinal plant known for its diverse phytochemical composition; however, information on the lipophilic constituents of its different organs remains limited. This study aimed to characterize the lipophilic composition and associated bioactivi...

Perpetual Futures for Stocks: The SpaceX Pre-IPO Market

Robert Shiller proposed perpetual futures in 1993 to create derivative markets for assets that are illiquid or whose price cannot be observed directly. Cryptocurrency markets later built the instrument under a different funding rule. We give a single no-arbitrage result that nest...

The numbers don't add up on manure and fertiliser: one-pager

The EU wants to reduce its dependency on imported fertilisers to boost the resilience and strategic autonomy of its food system, with the European Parliament claiming that livestock manure can reduce the EU’s reliance on imported fertilisers and that herd reductions may compromis...

Histone modification cross talk between a host and pathogen

ABSTRACT Bacterial pathogens modulate host cell physiology by secreting effector proteins that rewire host signaling pathways. A subset of these effectors directly modify host chromatin to reprogram gene expression and promote infection. While these enzymes are thought to functio...

Extracellular matrix composition and stiffness regulates progesterone responsiveness and decidualization

Endometriosis is an inflammatory disease of endometrium found outside the uterus. Approximately a third of patients remain unresponsive to hormonal treatments due to progesterone resistance. Because endometriosis lesions are found within fibrotic extracellular matrix (ECM), we hy...

Varying Gravity from a Modified Fractional Model: Observational Constraints and Slow–Fast Dynamics

We investigate a fractional gravity model in which both the Hubble parameter and the gravitational constant evolve dynamically due to fractional renormalization-group effects. The model incorporates a scalar field coupled to a time-varying G, generating nonlocal corrections chara...

Perceptions and attitudes toward patient safety: perspectives of students in the medical and health sciences at the University of Aden, Yemen

Abstract Background Patient safety competencies remain insufficient among health sciences graduates, especially in conflict-affected areas. This study assessed perceptions and attitudes toward patient safety among undergraduate medical students at the University of Aden, Yemen. M...

Guaranteed Authenticity via Logic: The Three-Determination (AOE) Theory of Sufficient and Necessary Conditions

The global fine art market suffers from pervasive authenticity threats, including high-precision manual replicas, AI-generated forgeries, commissioned ghost artworks, and physical piece substitution across paintings, sculptures, prints, and digital art. Three dominant authenticat...

Evaluation of Pyrazolone-Based Hydrazones as Potential Therapeutic Agents Against Glioblastoma

Background: Glioblastoma (GBM) is the most aggressive subtype of malignant glioma. Current therapeutic options remain limited, highlighting the need for the development of novel compounds capable of improving the efficacy of standard treatments. This study aimed to evaluate the b...

Coastal North America In Situ Chlorophyll and Optical Dataset

Abstract. Chlorophyll is a crucial climate variable and remotely sensed satellite chlorophyll estimates are essential to understanding large-scale biological processes. Current ocean color chlorophyll algorithms, however, are less accurate in optically complex inland and coastal...

An Updated and Revised Dyadic Model of Partner Violence

Research on Intimate Partner Violence (IPV) has traditionally examined perpetrators and victims separately, limiting understanding of the relational processes that sustain violence. The present review builds on the dyadic model of partner violence by synthesizing findings from 12...

Finite-field QED corrections to vacuum birefringence and magnetar polarization transport

Abstract We study low-energy photon propagation in a constant magnetic field within the finite-field one-loop Heisenberg–Euler framework and apply the resulting mode-dependent refractive indices to magnetar polarization transport. In a centered-dipole model, the polarization-limi...

Inkjet-printed transparent zinc oxide optoelectronic synapse with photoinduced artificial plasticity

The development of scalable and cost-effective fabrication strategies for artificial synapses is critical for next-generation neuromorphic systems aimed at overcoming the von Neumann bottleneck in data-intensive applications. In this context, inkjet printing offers an attractive...

Compression of Polyconvex Envelopes of Isotropic Functions via Monotonic Input Convex Neural Networks

ABSTRACT This work presents a novel neural‐network compression approach for polyconvex envelopes of isotropic functions. The approach relies on a classical sufficient criterion for polyconvexity and is particularly suited for the representation of determinant‐constrained energy d...

Multi-Phase Micromechanical Homogenization Approach for Predicting the Elastic Modulus of Gypsum–Fly Ash Ternary Blend Concrete

This study evaluates the efficacy of micromechanical homogenization techniques for estimating the effective elastic modulus of sustainable concrete containing fly ash and recycled gypsum. In the absence of direct experimental measurements, a multi-phase computational framework wa...

R-MCTS: Retrospective Offline Correction for Multi-Agent LLM Task Planning

We present R-MCTS, a retrospective (offline) correction framework for LLM-based multi-agent embodied task planning: failed trajectories are recorded, a lightweight scorer estimates action quality from recorded data alone, a Monte Carlo Tree Search rooted at the failure point prop...

Multimodal 3D light-field and laser-speckle endoscopy

Minimally invasive surgery is a powerful technique that enables operations deep within the body while minimizing patient trauma and recovery time. Optical endoscopes are key to providing intraoperative vision but still face challenges due to the loss of essential senses, includin...

Waste-To-Energy Conversion for Sustainable Electricity Generation in Lagos, Nigeria: A Thermodynamic and Environmental Analysis

Rapid urbanization and increasing municipal solid waste generation in Lagos, Nigeria, have intensified environmental challenges and energy deficits. This study investigates the potential of waste-to-energy (WtE) conversion as a sustainable pathway for electricity generation, usin...

Sensor-Based Assessment of Upper-Limb Motor Control in Children and Adults Using Two-Dimensional Circular Target Tracking

Objective, portable sensor-based assessment of human motion is vital for monitoring motor development and designing rehabilitation applications. This study investigated upper-limb motor characteristics during 2D circular target tracking across different age groups and speeds. Fif...

The Black Hole Information Paradox: Origins, Battles, and Where We Stand Now

The black hole information paradox arises from the apparent conflict between Hawking radiation and the unitary evolution required by quantum mechanics. This review traces the development of the problem from Bekenstein's black hole entropy and Hawking's radiation calculation throu...
