A Self‐Organized Liquid Reaction Container for Cellular Memory

open access: yesAdvanced Science, EarlyView.
How cells restore epigenetic information lost during replication is not known. This work proposes a mechanism based on the formation of biomolecular condensates. These condensates are induced by the chromosome itself and serve as reaction vessels for reconstructing missing epigenetic markers.

Plants’ molecular behavior to heavy metals: from criticality to toxicity

open access: yesFrontiers in Plant Science
The contamination of soil and water with high levels of heavy metals (HMs) has emerged as a significant obstacle to agricultural productivity and overall crop quality.

Transient Antiskyrmion‐Mediated Topological Transitions in Isotropic Magnets

open access: yesAdvanced Science, EarlyView.
A transient antiskyrmion‐mediated pathway that drives repeated stripe‐to‐skyrmion transitions is revealed, producing a net increase in topological charge in isotropic Dzyaloshinskii–Moriya interaction films. Experiments and simulations identify the antiskyrmion as a metastable excitation, enabling stochastic bitstream generation for probabilistic ...

Mean sensitive, mean equicontinuous and almost periodic functions for dynamical systems

open access: yes, 2019
We show that an $R^d$-topological dynamical system equipped with an invariant ergodic measure has discrete spectrum if and only it is $\mu$-mean equicontinuous (proven for $Z^d$ before).

Highly Secure In Vivo DNA Data Storage Driven by Genomic Dynamics

open access: yesAdvanced Science, EarlyView.
Integrated computational‐biological programming enables secure in vivo data storage by generating code tables from either genomes or gene regulatory networks, expanding the encryption key space by over 100 orders of magnitude. Storing code tables within synthetic genes, genomes, or gene regulatory networks adds an additional layer of security by ...

Unraveling large-scale spatial patterns and key drivers of heavy metals uptake by plants

open access: yesEcological Indicators
Heavy metals (HMs) contamination of soils is a critical environmental issue of global concern. HMs transfer from soil to plants is a key pathway for human exposure to soil HMs.

Endothelial Cell‐Specific Molecule‐1 (ESM1): An Endogenous Anticoagulant and Protective Factor in Venous Thrombosis

open access: yesAdvanced Science, EarlyView.
This study identifies ESM1 as an endogenous anticoagulant that modulates venous thrombosis. It shows that ESM1 deficiency triggers vascular occlusion in zebrafish and mice, whereas its restoration or overexpression prolongs clot‐formation time. Mechanistic analyses reveal that ESM1 activates HCII through its dermatan‐sulfate chain, uncovering a ...

Application of HEC-HMS in a Cold Region Watershed and Use of RADARSAT-2 Soil Moisture in Initializing the Model

open access: yes, 2017
This paper presents an assessment of the applicability of using RADARSAT-2-derived soil moisture data in the Hydrologic Modelling System developed by the Hydrologic Engineering Center (HEC-HMS) for flood forecasting with a case study in the Sturgeon ...

A Quest for the Mechanism of Ultrahigh Resolution SEM Imaging

open access: yesAdvanced Science, EarlyView.
Using Monte Carlo simulations with explicit definitions of SE1 and SE2 align with a cascade secondary electron production model, this work shows that the 3D nanostructure modulated SE2 emission enhances other than to reduce topographical contrast via a “miniature Faraday cup” effect.

Mutability and importance of a hypermutable cell subpopulation that produces stress-induced mutants in Escherichia coli.

open access: yesPLoS Genetics, 2008
In bacterial, yeast, and human cells, stress-induced mutation mechanisms are induced in growth-limiting environments and produce non-adaptive and adaptive mutations.
