Exploration of Half‐Cycle Length of Converging Circular Wavy Duct with Diverging‐Outlet: Turbulent Water Dynamics

open access: yesAdvanced Theory and Simulations, EarlyView.
Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude

Excitation Energy Transfer between Porphyrin Dyes on a Clay Surface: A Study Employing Multifidelity Machine Learning

open access: yesAdvanced Theory and Simulations, EarlyView.
Inspired by natural light‐harvesting systems, this study computationally investigates a synthetic antenna by arranging cationic free‐base porphyrin molecules on an anionic clay surface. Using a multiscale quantum mechanics/molecular mechanics (QM/MM) approach combined with a multifidelity machine learning method, excitation energies are predicted ...

Energy Symmetry Breaking of Dirac and Weyl Fermions in Magnetized Spinning Conical Geometries

open access: yesAdvanced Theory and Simulations, EarlyView.
Exact solutions for relativistic fermions in magnetized, spinning conical geometries reveal defect‐induced symmetry breaking between fermion and antifermion energies. Energy levels depend on the magnetic field, background geometry, and fractionalized spin. When the defect's spin dominates, quantum effects diminish.

Stereotyped Subclones Revealed by High‐Density Single‐Cell Lineage Tracing Support Robust Development

open access: yesAdvanced Science, EarlyView.
Based on a well‐established in vitro directed differentiation model and an integrated analysis of high‐density cell lineage trees (CLTs) and single‐cell transcriptomes, it is demonstrated that many subclones are formed by sub‐CLTs resembling each other in terms of both cell type compositions and topological structures.

Topoisomerase I Inhibition in ETV4‐overexpressed Non‐Small Cell Lung Cancer Promotes Replication and Transcription Mediated R‐Loop Accumulation and DNA Damage

open access: yesAdvanced Science, EarlyView.
The oncogenic ETS factor ETV4 exerts a pleiotropic control over DNA replication both in a transcription‐dependent and ‐independent fashion in NSCLC cells. High‐ETV4 expression leads to R‐loop formation and DNA damage in response to TOP1 inhibition.

Protected Chaos in a Topological Lattice

open access: yesAdvanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Multi‐Mechanical Regulation of 3D Printed Triply Periodic Hyperbolic Surfaces via Fourier Synthesis‐Based Free Modeling

open access: yesAdvanced Science, EarlyView.
Arbitrary structural regulations of triple periodic hyperbolic surfaces are achieved using mathematical Fourier construction and 3D printing technology, enriching the geometric forms and achieving optimized mechanical behaviors. Abstract Triply periodic hyperbolic surfaces (TPHSs) have attracted significant attention due to their exceptional ...

ChromInSight: Revealing DNA Double‐Strand Breaks Through Chromatin Structural Insights With an Interpretable Graph Neural Network Framework

open access: yesAdvanced Science, EarlyView.
DSBs are the most critical genomic lesions. Using the ChromInSight framework, It is revealed that 3D chromatin structure, rather than linear distance, shapes cluster‐scene between hub‐Nodes and DSB loci. The “spatial isolation–damage containment” hypothesis is proposed to illustrate how the genome responds to genomic damage and offer a powerful tool ...
