Phase-Programmed Charge Routing Governs Kinetic and Thermodynamic Molecular Selectivity for Chemiresistive Sensors

Abstract Controlling molecular selectivity in chemiresistive gas sensors remains a fundamental challenge, particularly for chemically analogous analytes that generate indistinguishable electronic responses. Here, we demonstrate that polymorph-engineered MoS2/SnO2 heterointerfaces...

Potential of β-catenin inhibitors as a novel therapeutic strategy for PIK3CA/CTNNB1 double-mutant endometrial cancer

Abstract Endometrial cancer (EC) is one of the most prevalent gynecological malignancies. EC is characterized by limited therapeutic options and a substantial unmet medical need, particularly in advanced or metastatic stages. Although a high prevalence of concurrent PIK3CA and CT...

Adolescent pregnancy and adverse maternal and perinatal outcomes: a systematic review and meta-analysis

Adolescent pregnancy remains a major global public health concern, yet evidence on its association with a broad range of maternal and perinatal outcomes remains fragmented. We conducted a systematic review and meta-analysis of observational studies comparing adolescents (13–19 ye...

Benchmarking token mixers for efficient transformer-based learned video compression

Learned video compression has rapidly evolved, with recent approaches demonstrating potential in complex context modeling. However, these performance gains often come at the cost of significant complexity in both framework design and computation-heavy modules, obscuring the effic...

Rapid genome-wide purging following tsunami-induced hybridization in a stickleback population

Speciation is the process by which barriers to gene flow evolve between populations. As speciation approaches completion, genome-wide divergence can be maintained in the face of hybridization. Because real-time observations of genomic changes following hybridization in natural po...

Orbital-Selective Coexistence of Interlayer Spin-Singlet Formation and SDW Order with Anomalous Spin Reconfiguration in Bilayer Nickelate La 3 Ni 2 O 7 Revealed by 17 O-NMR

The spin structure of the spin density wave (SDW) order in the bilayer nickelate La 3 Ni 2 O 7 has been investigated using site-selective 17 O-NMR measurements on the inner apical O(1), outer apical O(2), and planar O(3,4) sites. Below T SDW (= 150 K), the peak of all planar O(3,...

The Permutation Property of Greedy Sequences under a Density Condition on the Forbidden Set: Applications to OEIS A121878 and A329405

Let B be a set of positive integers, called the forbidden set. Consider the greedy sequence obtained by repeatedly choosing the smallest unused positive integer whose sum with each of the previous at most r terms does not belong to B. If B has natural density β, then under the co...

Sustained NAD⁺ augmentation by high-dose nicotinamide mononucleotide supplementation in older adults: a 24-week randomized, double-blind, placebo-controlled trial

Abstract In animal studies, the administration of nicotinamide mononucleotide (NMN), a precursor of nicotinamide adenine dinucleotide (NAD⁺), can ameliorate aging-related diseases by increasing tissue and blood NAD⁺ levels. However, human data on this intervention are limited. In...

Origin of Regioselectivity in C–H Bond Scission by Radicals: Quantitatively Predicting Effect of Electrophilicity Using Adamantane

Abstract Hydrogen abstraction is a key step in the oxidation of saturated hydrocarbons and the functionalization of C–H groups via hydrogen atom transfer. To evaluate and predict the regioselectivity of active species in these reactions, adamantane has long been utilized as a pro...

Emergence of Goal‐Directed Behaviors via Active Inference With Self‐Prior

ABSTRACT Infants often exhibit goal‐directed behaviors, such as reaching for a sensory stimulus, even when no external reward criterion is provided. These intrinsically motivated behaviors facilitate spontaneous exploration and learning of the body and environment during early de...

The Mysterious Case of Iron in XMPs: Anomalous High log(Fe/O) Observed in Extremely Metal-Poor Galaxies HSCJ1631+4426 and SDSSJ0811+4730

Abstract We present integral field spectroscopic observations of two local extremely metal-poor galaxies (XMPs), HSCJ1631+4426 and SDSSJ0811+4730, obtained with the Keck Cosmic Web Imager (KCWI) over 3545 − 5529 Ã at a spectral resolution of R ~ 3600, capturing bright nebular emi...

Strain Correlated Linearly Polarized Photoluminescence in WSe2/WS2 Moire Superlattices

Abstract Reliable optical control of valley degrees of freedom in moiré excitons requires that the emitted polarization faithfully reflects the underlying valley state. Here, we show that linearly polarized photoluminescence from WSe2/WS2 moiré excitons is largely insensitive t...

Aberrant salience is selectively associated with ventral midbrain connectivity to the dorsal but not ventral striatum

The dorsal midbrain-striatal dopaminergic stream encodes salience in animals, while it’s unknown in humans. The midbrain-striatal dopaminergic hyperactivity is postulated to attribute aberrantly-heightened salience to ordinary stimuli, forming delusion and hallucination. While an...

Total-energy-assisted Tight-binding Method Based on Density Functional Theory — Design Principles Toward Transferability and Extrapolation

The previously proposed tight-binding (TB) method derived from the total energy has been extended within the local density approximation [TE-TB method; J. Phys. Soc. Jpn. 87, 064802 (2018) ]. Unlike the earlier two-parameter formulation, the present method introduces three parame...

Measurements of the production of W$$^{\pm }$$ and Z$$^0$$ bosons in pp collisions at $$\sqrt{s} = 13$$ TeV

Abstract Measurements of the production of the W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons at midrapidity in pp collisions at $$\sqrt{s} = 13$$ s = 13 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons are detected via their (di)e...

Early metal-enriched baryon cycling before the midpoint of cosmic reionization

Abstract Models predict that chemical enrichment and gas redistribution should begin rapidly once star formation starts, but direct constraints at the earliest epochs have been scarce. Here we show that metal-enriched gas in multiple ionic phases was already present around galaxi...

Sequential monitoring for robot teams via temporal logic planning and persistent coverage control

This paper proposes a multi-layer control framework for monitoring environments composed of subregions under Linear Temporal Logic (LTL) specifications. Task specifications described in natural language are translated into LTL formulas for temporal logic planning. An intermediate...

A Unified Framework for Motion Estimation and Online Camera Orientation Calibration Using a Ground-View Event Camera

Accurate motion estimation and online camera orientation calibration are important for onboard vision systems on ground vehicles. Ground-view sensing is attractive for these tasks because the ground is typically static, close to the vehicle, and continuously observable, but fast...

The Relationship Between Selective Serotonin Reuptake Inhibitor Use and Delayed Bleeding After Colorectal Endoscopic Resection: A Nationwide Retrospective Cohort Study

Selective serotonin reuptake inhibitors (SSRIs) are associated with an increased risk of gastrointestinal bleeding. However, their effect on delayed bleeding after colorectal endoscopic resection (CER) remains unclear. We evaluated the association between SSRI Use and delayed ble...
