Dark-State-Mediated Low-Energy Electron Attachment to Molecular Oxygen: Symmetry Adapted Decomposition of the DEA Resonance through Dyson-Orbitals’ Incoherent Mixing

Abstract Dissociative electron attachment (DEA) to O2 exhibits a prominent resonance peak at ∼6.5 eV, producing O– with a single kinetic energy band (∼1.5 eV) and a distinct four-lobed angular distribution. Using velocity-map imaging and complex absorbing potential equation-of-mo...

A Multi-Stage Deep Learning Framework for Daily PM2.5 Estimation at 100 m Resolution Across the Contiguous United States, 2000–2024 (A Quarter Century of Data)

Abstract Accurate high-resolution estimation of fine particulate matter (PM2.5) remains challenging because of sparse monitoring networks and missing satellite observations. We developed a multistage deep learning framework to generate daily PM2.5 concentrations at 100 m resoluti...

Computational Insights into Mn and Fe Azoaromatic Pincer Complexes: Modulating Ligands for Enhanced CO2-to-Formic Acid Conversion

Abstract Formic acid, produced by hydrogenation of CO2, is an attractive liquid organic hydrogen carrier. It offers a promising route for sustainable energy storage; however, its practical application remains constrained by the need for strong basic conditions. Here, we used DFT...

Functionalized WS2 Electronic Nose for Volatile Organic Compound Mixture Recognition via Chemically Informed Transformer Learning

Abstract Accurate detection and discrimination of volatile organic compounds (VOCs) in complex environments using chemiresistive sensors remains a major challenge, mainly due to overlapping responses (cross-sensitivity) and environmental interferences. In this study, we have deve...

Birth Order Effects in Maternal Health‐Seeking Behavior: Evidence From India

ABSTRACT Can maternal health‐seeking behavior change with subsequent births? Using two rounds of India's National Family Health Survey and within‐mother comparisons, we document a decline in institutional delivery, skilled attendance, and antenatal care after the first birth. We...

Caste in the Boardroom, and Beyond: What’s Missing and Where to Next?

An empirical literature on caste in Indian firms – boards, CEOs, capital and labour intermediaries – has emerged in management journals over the past decade. This commentary reads the field’s findings against what economics has long established and asks what comes next.

Must Longtermists Wish Us All Dead? A Quadrilemma

ABSTRACT Longtermists assign great moral importance to making the long‐term future as good as possible, especially by ensuring the survival of humanity. We argue, to the contrary, that on assumptions that are plausible, conservative, or shared by leading longtermists, human extin...

MudraGen: Geometrically Supervised Generation of Interacting Two-Hand Mudras for preserving Indian Classical Dance Heritage

Automatic generation of hand gestures is essential for the transmission of Indian classical dance and critical for its preservation. Indian classical dance gesture datasets are inherently low-resource, and the canonical Sanskrit definitions of many mudras lack precise textual des...

Scaling limit of a drainage network model on a perturbed lattice

Abstract The study of random networks generally requires that vertices be independently and uniformly distributed over disjoint regions such as a Poisson point process. In this work, we venture beyond this standard paradigm and investigate a stochastic forest obtained from a drai...

A text analytics based study of indian consumer attitudes toward adoption of sustainable products for circular economy

The adoption of circular economy strategies is only possible through proper education among young minds. However, to build an effective education model, it is necessary to consider knowledge gaps and current consumption patterns. The best option for daily-use products, around whi...

Unraveling single-molecule reactions via multiplexed in-situ DNA sequencing

Abstract DNA sequence regulates complex reactions and protein-DNA interactions, yet sequence effects remain poorly understood due to the lack of direct, high-throughput approaches to study sequence-dependence at the single-molecule level. Here, we introduce Single-molecule Phenot...

Energetic Determinantsof Expanded PAM Recognitionin Engineered FnCas9

Abstract Expanding protospacer-adjacent motif (PAM) compatibility while preserving specificity remains a central challenge in CRISPR–Cas9 engineering. Francisella novicida Cas9 (FnCas9) exhibits high intrinsic specificity but is constrained by stringent PAM requirements. Here, we...
