Reconfiguration of Multiphase Coacervate Droplets Into Self‐Regulated Nested Artificial Cells

open access: yesAngewandte Chemie, EarlyView.
Living cells advance functionality through spatiotemporal sub‐compartmentalization and internal organization. Herein, we develop a self‐regulated artificial cell by transforming a membrane‐less multiphase coacervate droplet (MCD) into a membranized, structurally reinforced nested coacervate vesicle (NCV).

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Haplotype‐Resolved 3D Genomic Landscapes and Their Impacts on Agronomic Traits in Grapevine

open access: yesAdvanced Science, EarlyView.
This study presents a haplotype‐resolved 3D genomic landscape of grapevine, revealing that structural variations (SVs) are closely associated with phased topologically associating domain (TAD) boundary transitions. These rearrangements coordinate with allele‐specific DNA methylation (ASM) and allele‐biased gene expression (ASE) to shape key agronomic ...

Robust Fractional Low Order Adaptive Linear Chirplet Transform and Its Application to Fault Analysis

open access: yesEntropy
Time-frequency analysis (TFA) technology is an important tool for analyzing non-Gaussian mechanical fault vibration signals. In the complex background of infinite variance process noise and Gaussian colored noise, it is difficult for traditional methods ...

A Conceptual Framework for Integration of Evidence-Based Design with Lighting Simulation Tools

open access: yesBuildings, 2017
The use of lighting simulation tools has been growing over the past years which has improved lighting analysis. While computer simulations have proven to be a viable tool for analyzing lighting in physical environments, they have difficulty in assessing ...

A Question of Coherence [PDF]

open access: yes, 2016
open1noElectromagnetic waves were first postulated by James Clerk Maxwell (1831-1879) in 1865. To demonstrate their existence 22 years later, Heinrich Hertz (1857-1894) had to design new instrumentation that he used to carry out an experiment than had ...

Modulating the Charge Transfer Channels via Constructing Charge‐Assisted Hydrogen‐Bonded Organic Frameworks for Enhanced Photosynthesis of Hydrogen Peroxide

open access: yesAdvanced Science, EarlyView.
This work reports a strategy of engineering charge‐assisted hydrogen bonds to tailor charge transfer channels in HOFs, significantly improving their performance in photocatalytic H2O2 production. ABSTRACT The production of H2O2 via artificial photosynthesis is often limited by inefficient charge‐carrier separation, causing significant charge ...

Protocol for the detection of proteolytic activity in female Aedes aegypti mosquito midgut extracts using fluorogenic AMC protease substrates

open access: yesSTAR Protocols
Summary: Female Ae. aegypti mosquitoes utilize midgut proteolytic enzymes to digest blood meal proteins, but activity detection has largely depended on the use of chromogenic substrates.

Antimicrobial Profiling of Bacteria Isolated from Fish Sold at Informal Market in Mufakose, Zimbabwe

open access: yesInternational Journal of Microbiology, 2019
The number of infections caused by antibiotic resistant bacteria is rising worldwide. Fish from multisource pollution waters can harbour multidrug-resistant bacteria that can be disseminated to humans through eating or contact of contaminated fish.
