Non-asymptotic oracle inequalities for the Lasso in high-dimensional mixture of experts

Abstract We study Lasso estimation for high-dimensional softmax-gated Gaussian mixture-of-experts (SGMoE) regression models, where the predictor dimension P may exceed the sample size N . Under bounded parameters, we establish a non-asymptotic Kullback–Leibler (KL) oracle inequal...

Global origins of tuna and billfish fisheries reveal the transition from coastal access to oceanic exploitation

Ocean ecosystems have played a crucial role in people’s lives around the world for millennia. However, questions persist about when, why, and how people first began removing biomass from offshore habitats and established fisheries in distant, oceanic environments. We explore the...

Tracking crop evapotranspiration and water stress across seasons using multi-sensor UAV observations

Abstract. Field-scale estimation of evapotranspiration (ET) using high-resolution data supports water conservation and yield optimization by enabling localized water use monitoring and early detection of crop stress. This study applies the Priestley–Taylor Two-Source Energy Balan...

Real‐Life Psychological Experiences and Cardiac Autonomic Physiology Among Survivors of a Myocardial Infarction in Midlife

Abstract Middle-aged women with ischemic heart disease have a higher burden of psychosocial factors compared with male counterparts. Data on daily life stress and autonomic physiology could help guide targeted interventions. We studied 302 individuals ≤ 61 years of age (129 women...

Airborne measurements of turbulence and cloud microphysics during PaCE 2022 using the Advanced Max Planck CloudKite Instrument (MPCK + )

Abstract. This paper presents the data set collected with the Advanced Max Planck CloudKite instrument (MPCK+) during the Pallas Cloud Experiment (PaCE), conducted at Pallas, Finland, between September 19 and September 26, 2022. The data set includes measurements of turbulence, w...

Who Gains from creative destruction? Evidence from high-quality entrepreneurship in the United States

The question of who gains from high-quality entrepreneurship is crucial to understanding whether investments in innovative startup firms produce socially beneficial outcomes. Although entrepreneurship is widely viewed as a central driver of economic growth, recent research has ra...

Free-Monodromic Mixed Tilting Sheaves on Flag Varieties

In this paper we propose a construction of a monoidal category of “free-monodromic” tilting perverse sheaves on (Kac–Moody) flag varieties in the setting of the “mixed modular derived category” introduced by the first and third authors. This category shares most of the properties...

Estimates for modular theory in algebraic QFT

The general scope of this PhD thesis is to establish relations between Tomita-Takesaki modular theory, in particular modular Hamiltonians and relative modular Hamiltonians, and physically better understood quantities, such as the stress-energy tensor, energy densities or other mo...

Discovery of Pyrazolopyrimidines as Potent and Orally Bioavailable MRGPRX2 Antagonists

Abstract The Mas-related G protein-coupled receptor X2 (MRGPRX2) mediates IgE-independent mast cell activation and is implicated in pseudoallergic drug reactions, chronic urticaria, atopic dermatitis, rosacea, neurogenic inflammation, and other mast cell-mediated disorders. Herei...

MUDGAPARNI (VIGNA TRILOBATA LINN.): A CLASSICAL REVIEW

Mudgaparni (Vigna trilobata Linn.) is an important medicinal plant described in Ayurveda for its rejuvenative and therapeutic properties. Although extensively documented in classical literature information regarding its classification, synonyms, pharmacodynamic attributes, therap...

PHYTOCHEMICAL PROFILING, CHROMATOGRAPHIC FINGERPRINTING AND IN VITRO ANTIBACTERIAL EVALUATION OF METHANOLIC LEAF EXTRACT OF WRIGHTIA TINCTORIA (ROXB.) R.BR.

Wrightia tinctoria (Roxb.) R.Br. is a medicinal plant of the family Apocynaceae with a history of traditional use in India. The present study evaluated the leaves of W. tinctoria collected from Vazhani, Thrissur, Kerala, using phytochemical, chromatographic, antibacterial and spe...

AN INFERIOR POLAR ACCESSORY RENAL ARTERY - A CADAVERIC CASE REPORT OF A RENAL ARTERIAL VARIATION

The renal arteries are classically described as paired lateral branches of the abdominal aorta that enter the renal hilum. However, additional or accessory renal arteries are well-recognized anatomical variants and may enter the kidney through the hilum or directly through a rena...

PDA-Assisted Fabrication of Calcium Alginate Hydrogel-Coated Stainless Steel Meshes for High-Efficiency Oil/Water Separation

Abstract This study introduces an environmentally friendly and straightforward dip-coating technique for preparing stainless steel meshes (SSM) coated with calcium alginate (CA) hydrogel. The prepared mesh possesses high hydrophilicity and underwater superoleophobicity, enabling...

Corporate ethical and responsible AI (CERAi) and AI trustworthiness: a lifecycle perspective and empirical insights

Purpose This study develops and empirically validates a Corporate Ethical and Responsible AI (CERAi) lifecycle framework. The framework comprises three interdependent stages: design and development, testing and training, and deployment and usage. The study aims to move the resear...

Investor herding under extreme uncertainty: evidence from Asia-Pacific equity markets during COVID-19

Purpose This study examines whether COVID-19-related extreme uncertainty coincided with time-varying herding in six Asia-Pacific equity markets and the United States, whether the pattern was pandemic-specific, and whether herding intensity was associated with US monetary conditio...

A Computational Pipeline for Patient-Level Gene-Expression Analysis in Colorectal Cancer

Group-level differential expression does not show whether gene-expression changes are consistent across individual patients. I developed a Python-based computational pipeline to evaluate patient-level consistency using a publicly available colorectal cancer RNA-sequencing dataset...

THE EVALUATION OF EFFECT OF BOERHAVIA DIFFUSA (L) ON WOUND HEALING ACTIVITY ON MICE

The study aimed to investigate the phytochemical profile and wound healing efficacy of Boerhavia diffusa leaves. Plant material was collected from Deori, Sagar district, and authenticated by the Department of Botany, Dr. H.S. Gour University, Sagar (M.P.). Soxhlet extraction was...

Apparent versus Cross-Validated Selectivity in Seawater Electrolysis: Linking Product Analysis to Catalyst–Electrolyte Interface Dynamics

Selectivity in seawater electrolysis is commonly evaluated by comparing the oxygen evolution reaction (OER) and chlorine evolution reaction (CER). However, the products measured after electrolysis do not always directly represent those initially formed at the catalyst-electrolyte...

The Projective Confluence: Dismantling the Four Pillars of Lambda-CDM Consensus via Non-Ontological Phase Separation

Following the systemic indexation of our geometric paradigm, institutional astrophysics has retreated into the defensive perimeter of the standard cosmological model ($\Lambda$CDM), citing four "independent" observational baselines as definitive proofs for the physical existence...
