Applying an adaptationist framework to personality science: jealousy as a mechanistic basis of Emotionality

Over the past half century, the field of personality psychology has developed several descriptive taxonomies, but progress toward a genuinely explanatory framework for between- and within-person variation in psychology and behavior has been elusive. We argue that this is largely...

Performant Tridiagonal Factorization of Skew-Symmetric Matrices

Abstract. The factorization of skew-symmetric matrices is a critically understudied area of dense linear algebra, particularly in comparison to that of general and symmetric matrices. While some algorithms can be adapted from the symmetric case, the cost of algorithms can be redu...

Evaluating spectral unmixing techniques using imaging spectroscopy data for retrieval of green, non-photosynthetic vegetation, and soil fractional cover

Estimates of fractional cover of green vegetation (GV), non-photosynthetic vegetation (NPV), and soil provide valuable information about the Earth system. As the new generation of Earth visible-to-shortwave infrared (VSWIR) imaging spectrometers take orbit, global fractional cove...

Matrix Stiffness Regulates Mechanotransduction and Vascular Network Formation of hiPSC-Derived Endothelial Progenitors Encapsulated in 3D Hydrogels

Abstract Matrix mechanics are central to vasculogenesis, yet stiffness is often confounded with ligand density or degradability in common hydrogel platforms. Here, we use norbornene-modified hyaluronic acid (NorHA) hydrogels to independently tune stiffness within a sub-kilopascal...

Speed Limits on Biomolecular Processes from Fundamental Physical Constants

Abstract Many of the time scales of life have speed limits set by quantum-mechanical constraints along with nonfundamental quantities, such as the temperature of the environment, which are however bounded by anthropic considerations. Here, some of such speed limits are examined,...

IFNγ-dependent tumor-cell MHC-II is restrained by MAPK signaling and associated with immunotherapy responsiveness in pancreatic ductal adenocarcinoma

Abstract Pancreatic ductal adenocarcinoma (PDAC) is characterized by an immunosuppressive tumor microenvironment (TME) and poor prognosis. Although major histocompatibility complex class II (MHC-II) is typically expressed by professional antigen-presenting cells, its regulation a...

Nano Borophene as a Programmable 2D Scaffold for Organized DNA Assembly and Long‐Range Energy Transfer

ABSTRACT Two‐dimensional borophene, with its electron‐deficient bonding and structural polymorphism, is an emerging platform for constructing organized nano‐bio interfaces. In this work, we demonstrate molecularly programmed borophene‐DNA nanoarchitectures by interfacing χ 3 ‐pha...

Technology Use in the Black Church: Perspectives of Black Church Leaders

Black Churches serve as a central faith-based institution across America. As digital technologies become increasingly prevalent in religious contexts, understanding how Black Church leaders navigate these tools is crucial. Yet, few researchers have explored how Black Church leade...

Constructing Algorithmic Authority: How Multi-Channel Networks (MCNs) Govern Live-Streaming Labor in China

This study examines the discursive construction of algorithms and its role in labor management in Chinese live-streaming industry by focusing on how intermediary organizations (Multi-Channel Networks, MCNs) actively construct, stabilize, and deploy particular interpretations of p...

The Relational Origins of Rules in Online Communities

Where do rules come from in online communities? This study investigates how and why online communities adopt and change their rules. We conducted a grounded theory-based analysis of 40 in-depth interviews with community leaders from subreddits, Fandom wikis, and Fediverse servers...

Transcranial Infrared Laser Stimulation Enhances Emotion Regulation and Is Associated With Prefrontal Cortex Connectivity

Emotion regulation depends on top-down prefrontal control of affective responses, and noninvasive prefrontal neuromodulation may augment this capacity. We tested whether enhancing prefrontal cortex function before cognitive reappraisal improves emotion regulation in healthy adult...

Ritualization of Complex Skill Acquisition

Abstract The processes by which traditional artistic knowledge is transmitted across generations with high fidelity remain poorly understood, particularly in non-Western contexts. This study examines how mastery of Indian miniature painting, a technically demanding and culturally...

Synthesis of α-Halophosphonates via Copper-Catalyzed Atom Transfer Radical Addition

Abstract α-Substituted alkylphosphonates and phosphates have broad utility in the pharmaceutical, agrochemical, and commodity chemical industries. Herein, we present the copper-catalyzed atom transfer radical addition (ATRA) of alkyl halides to alkenylphosphonates for the synthes...

Improving Competitiveness: A Freelancer-Centric Approach for Recommending Reskilling Strategies

Online labor markets play a vital role in connecting freelancers and employers worldwide. While most existing methods focus on helping employers find the best candidates, relatively little research addresses freelancer-centric approaches. In this study, we propose a freelancer-ce...

Numerical modeling of aeolian-dune development in carbonate island settings: exploring last interglacial environmental conditions on coastal dune morphology in The Bahamas and Turks and Caicos

Abstract This paper presents an adaptation to the Aeolian Surface Model (ASM) framework, modified to account for variable surface properties and sediment transport limitations present in coastal carbonate-dune environments. The model simulates the formation of three fossilized du...

The Role of Charge Transfer and Parity Symmetry of the Wave Function in N , N ′-Bis(2-phenylethyl)-3,4,9,10-perylenedicarboximide Crystals: A Frenkel-Holstein Approach

Abstract Charge-transfer (CT) configurations can provide an efficient pathway to the triplet pair (TT) manifold in singlet fission (SF), yet diagnosing CT-mediated TT participation from optical spectra remains challenging because TT signatures are often weak, obscured, or missing...

De Novo Design and Structural Optimization of Mn(salen)‐Based Artificial Metalloenzymes for Asymmetric Sulfoxidation

ABSTRACT Artificial metalloenzymes (ArMs) exhibit exceptional selectivity, yet extending their reactivity beyond native cofactors remains a major challenge. While previous designs using native protein scaffolds to incorporate nonnative cofactors have been reported, de novo protei...

Frequent Use of Restricted Oral Intake During Hospitalization for IBD Flares Was Not Associated with Improved Clinical Outcomes: A Multicenter Retrospective Cohort Study

There are limited indications for bowel rest in hospitalized patients with inflammatory bowel disease (IBD) flares, particularly in patients with only inflammatory disease (i.e., no obstruction, abscess, or fistula). We aimed to assess the frequency of restricted oral intake and...

CiliaIO: Machine learning reveals spatial patterns of cilia beating dynamics in the zebrafish spinal cord

Motile cilia generate fluid flows that are essential for normal development and physiology. Cilia display diverse beating waveforms, and while pronounced defects are strongly associated with motile ciliopathies, subtler alterations also influence disease manifestations. Finer qua...

Five-Year Cost-Effectiveness Analysis of Endoscopic Third Ventriculostomy With Choroid Plexus Cauterization Versus Ventriculoperitoneal Shunting in Postinfectious Hydrocephalus in a Low-Income Setting

BACKGROUND AND OBJECTIVES: For over 2 decades, an emerging body of data has established endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC) as a viable option in the treatment of postinfectious hydrocephalus (PIH) in low-resource settings with similar out...
