Holomorphic supergravity in ten dimensions and anomaly cancellation

Journal of High Energy Physics
We formulate a ten-dimensional version of Kodaira-Spencer gravity on a Calabi-Yau five-fold that reproduces the classical Maurer-Cartan equation governing supersymmetric heterotic moduli.

Topological Phase Transition in a One-Dimensional Elastic String System

Crystals, 2019
We show that topological interface mode can emerge in a one-dimensional elastic string system which consists of two periodic strings with different band topologies.

Topology of strings: Median string is NP-complete

Theoretical Computer Science, 2000
Given a set of strings, the problem of finding a string that minimises its distance to the set is directly related with problems frequently encountered in areas involving pattern recognition or computational biology. Based on the Levenshtein (or edit) distance, different definitions of distances between a string and a set of strings can be adopted.

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.

String topology for Lie groups [PDF]

Journal of Topology, 2010
In 1999 Chas and Sullivan showed that the homology of the free loop space of an oriented manifold admits the structure of a Batalin-Vilkovisky algebra. In this paper we give a direct description of this Batalin-Vilkovisky algebra in the case that the manifold is a compact Lie group G. Our answer is phrased in terms of the homology of G, the homology of

Functionally complementary bacterial inoculant coordinates arbuscular mycorrhizal fungi to improve Angelica sinensis root yield and quality

iMetaOmics, EarlyView.
Comprehensive understanding of how diverse PGPR strains enhance the rhizosphere microenvironment remains a considerable challenge. Here, we provide experimental evidence that a functionally synergistic composite microbial formulation can markedly enhance growth performance and improve the quality attributes in Angelica sinensis.

Topological structures, dark matter and gravitational waves in E6

Journal of High Energy Physics
We discuss the appearance of topological structures from the spontaneous breaking of E 6 to the Standard Model via its maximal subgroup SO(10) × U(1) ψ . They include dumbbells, metastable strings, as well as domain walls bounded by necklaces. We provide

Decoding temporal miRNA signatures of semen under in vitro exposure for forensic time since deposition estimation using machine learning‐driven modeling

Interdisciplinary Medicine, EarlyView.
This study develops a novel miRNA‐based framework for estimating the time since deposition of semen stains, combining small RNA sequencing with machine learning. Time‐dependent miRNA modules were identified using Mfuzz clustering and WGCNA, followed by a multi‐stage feature selection pipeline that reduced 261 candidate miRNAs to a minimal 7‐miRNA panel.

SO(10) Cosmic Strings and SU(3) Color Cheshire Charge

, 1993
Certain cosmic strings that occur in GUT models such as $SO(10)$ can carry a magnetic flux which acts nontrivially on objects carrying $SU(3)_{color}$ quantum numbers.
