Finite sigma models and exact string solutions with Minkowski signature metric

, 1992
We consider $2d$ sigma models with a $D=2+N$ - dimensional Minkowski signature target space metric having a covariantly constant null Killing vector. These models are UV finite. The $2+N$-dimensional target space metric can be explicitly determined for a

Urolithin A, a Diet‐Derived Gut Microbial Metabolite Against Pulmonary Hypertension Identified via Molecular Docking, Molecular Dynamics and Surface Plasmon Resonance

Food Safety and Health, EarlyView.
Urolithin A, a gut microbial metabolite, binds TNF to suppress proliferation, inflammation, and oxidative stress, offering a promising microbe‐derived therapeutic avenue for pulmonary hypertension. ABSTRACT Pulmonary hypertension (PH) is a complex and multifactorial disease that poses a significant clinical challenge.

Polymer informatics: Integrating data‐driven strategies, advanced machine learning, and automated synthesis for next‐generation polymer design

InfoScience, EarlyView.
Designing new polymers for applications such as sustainable plastics, biomaterials, and 3D printing has traditionally been slow and expensive, relying heavily on trial‐and‐error experiments. This review shows how polymer informatics—the integration of large polymer databases, machine‐learning models, and automated robotic synthesis—enables fast ...

The A(I) Team: Effects of Human‐Likeness and Conformity to Gender Stereotypes on Initial Trust and Willingness to Work With an AI Teammate

Journal of Organizational Behavior, EarlyView.
ABSTRACT As artificial intelligence (AI) technologies progress, AI agents arise as potential teammates in the workplace. This study explores how the visual representation of the AI agent as well as its conformity to traditional gender stereotypes affects the manifestation of uncanny valley effects in a workplace team context.

On mirror maps for manifolds of exceptional holonomy

Journal of High Energy Physics, 2019
We study mirror symmetry of type II strings on manifolds with the exceptional holonomy groups G 2 and Spin(7). Our central result is a construction of mirrors of Spin(7) manifolds realized as generalized connected sums.

Two-Dilaton Theories in Two Dimensions from Dimensional Reduction

, 2001
Dimensional reduction of generalized gravity theories or string theories generically yields dilaton fields in the lower-dimensional effective theory. Thus at the level of D=4 theories, and cosmology many models contain more than just one scalar field (e ...

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

AI/ML Enabled High‐Throughput Design and Synthesis for Energetic Molecules

Materials Genome Engineering Advances, EarlyView.
Novel design methods for a special kind of functional molecules — the energetic molecules—are summarized. Both classic Machine Learning (ML) and Artificial Intelligence (AI) generative models are utilized for the high‐throughput design of these energetic molecules, and a sort of high‐energy low‐sensitivity molecules are obtained.

W $$ \mathcal{W} $$ algebras are L∞ algebras

Journal of High Energy Physics, 2017
It is shown that the closure of the infinitesimal symmetry transformations underlying classical W $$ \mathcal{W} $$ algebras give rise to L∞ algebras with in general field dependent gauge parameters.

Accelerating the prioritisation of plant species with underexplored medicinal potential: The pm4mp (Phylogenetic Methods for Medicinal Plants) R package

PLANTS, PEOPLE, PLANET, EarlyView.
Medicinal plants used in ethnobotanical traditions to treat or prevent diseases have gained renewed interest for their largely untapped potential in drug discovery. In this study, we developed and tested novel methods to prioritise plant species based on their unexplored medicinal potential. By enabling researchers to target the most promising species,
