A microscopic realization of dS$_3$

open access: yesSciPost Physics
We propose a precise duality between pure de Sitter quantum gravity in $2+1$ dimensions and a double-scaled matrix integral. This duality unfolds in two distinct aspects.

Cockroach‐Derived Leucokinin VIII Peptide Accelerates Diabetic Skin Wound Healing by Enhancing Keratinocyte Filopodia Formation

open access: yesAdvanced Science, EarlyView.
This study identifies the cockroach‐derived peptide leucokinin VIII as a potent accelerator of diabetic wound healing. By activating the FAK‐ACTG1 axis, the peptide drives keratinocyte migration and filopodia formation. Delivered via a developed PLGA‐PEG‐PLGA thermosensitive hydrogel for sustained release, this approach significantly hastens wound ...

Detachment‐Induced FAK‐STAT3‐NNMT Inhibits CTCs Anoikis to Promote Breast Cancer Metastasis by Enhancing Fatty Acid Oxidation

open access: yesAdvanced Science, EarlyView.
The FAK‐STAT3‐NNMT axis drives anoikis resistance in circulating tumor cells by reprogramming fatty acid oxidation. Targeting this metabolic vulnerability suppresses metastasis, untangling a key mechanism of breast cancer progression and revealing NNMT as a promising therapeutic target.

SATB2 Mediates H3K9 Delactylation by Recruiting HDAC3 to Repress LCN2 and Inhibit Lung Tumor Growth and Metastasis

open access: yesAdvanced Science, EarlyView.
This study highlights the capacity for tumor suppressor SATB2 to recruit HDAC3 and catalyze histone H3K9 delactylation, thereby repress transcription of the oncogene LCN2. This novel epigenetic‐metabolic axis inhibits the growth and metastasis of non‐small cell lung cancer, delineating a new mechanistic pathway with potential therapeutic relevance ...

JT gravity from non-Abelian T-duality

open access: yesJournal of High Energy Physics
We study the geometries obtained by performing super non-Abelian T-duality of the Principal Chiral Model on OSp(1|2). While the initial model represents an appropriate 3D supergravity background, interpretable as the superspace version of AdS3, the T ...

ML Workflows for Screening Degradation‐Relevant Properties of Forever Chemicals

open access: yesAdvanced Science, EarlyView.
The environmental persistence of per‐ and polyfluoroalkyl substances (PFAS) necessitates efficient remediation strategies. This study presents physics‐informed machine learning workflows that accurately predict critical degradation properties, including bond dissociation energies and polarizability.

Current‐Driven Nonreciprocal Response of Nonequilibrium Skyrmions

open access: yesAdvanced Science, EarlyView.
A skyrmion holds great promise for spintronic applications owing to its intrinsic topological stability and high mobility under ultra‐low current excitation. Here, by means of in situ electron microscopy, we demonstrate a skyrmion diode effect and the associated current‐driven nonreciprocal skyrmion dynamics in a designed FeGe‐based microdevice.

Cells Dynamically Adapt Their Nuclear Volumes and Proliferation Rates During Single to Multicellular Transitions

open access: yesAdvanced Science, EarlyView.
It is currently not well understood how cells regulate basic properties, e.g., volume and mechanics within dense multicellular environments like tumors. Here, we show that different cell types of cancer and also normal cells largely decrease their nuclear and cellular volumes in emerging cell clusters and that this is partly driven by cell cycle shifts.

Machine Learning for Designing Perovskites and Perovskite‐Inspired Solar Materials: Emerging Opportunities and Challenges

open access: yesAdvanced Science, EarlyView.
This review offers a comprehensive comparison between perovskites and perovskite‐inspired materials (PIMs), focusing on their crystal structures, electronic properties, and chemical compositions. It evaluates the applicability of machine learning (ML) descriptors and models across both material classes.

Duality Symmetries in String Theory

open access: yes, 1995
We review the status of duality symmetries in superstring theories. These discrete symmetries mark the striking differences between theories of pointlike objects and theories of extended objects. They prove to be very helpful in understanding non-perturbative effects in string theories.
