Intercellular Horizontal Transfer of TXNDC5 mRNA via Extracellular Vesicles Contributes to Tumor‐Associated Macrophage‐Mediated Prostate Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
This study investigates the role of M2 macrophage‐derived extracellular vesicles (M2 EVs) in prostate cancer (PCa) metastasis. Mechanistically, M2 EVs horizontally transfer TXNDC5 mRNA to PCa cells, where the molecule induces the mesenchymal‐like state (MLS), enhancing PCa migration and invasion.

Timescales of Polycyclic Aromatic Hydrocarbon and Dust Continuum Emission from Gas Clouds Compared to Molecular Gas Cloud Lifetimes in PHANGS-JWST Galaxies

open access: yesThe Astrophysical Journal
Recent JWST mid-infrared (mid-IR) images, tracing polycyclic aromatic hydrocarbons (PAHs) and dust continuum emission, provide detailed views of the interstellar medium (ISM) in nearby galaxies.

Formation history of open clusters constrained by detailed asteroseismology of red giant stars observed by Kepler

open access: yesEPJ Web of Conferences, 2017
Stars originate by the gravitational collapse of a turbulent molecular cloud of a diffuse medium, and are often observed to form clusters. Stellar clusters therefore play an important role in our understanding of star formation and of the dynamical ...

Regulation of Excitonic Behavior in Defective Acetylenic Polymers Enables Mechanism Switching in O2 Activation for Enhanced Water Decontamination

open access: yesAdvanced Science, EarlyView.
A molecular defect‐mediated charge accumulation strategy is developed to regulate the exciton behavior for selective molecular oxygen (O2)activation in poly(1,3,5‐triethynylbenzene) (PTEB). Artificial internal electric field (IEF) constructed in defective PTEB provides internal driving force to steer the directed migration of charge carriers, thereby ...

Deep Andromeda JCMT SCUBA-2 Observations. The Submillimeter Maps and Giant Molecular Clouds

open access: yesThe Astrophysical Journal Supplement Series
We have carried out unprecedentedly deep, nearly confusion-limited JCMT SCUBA-2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 μ m image with a ∼50 pc resolution yields a comprehensive catalog of 383 giant molecular clouds ...

Observations of the supernova remnant W28 at TeV energies [PDF]

open access: yes, 2000
The atmospheric Cerenkov imaging technique has been used to search for point-like and diffuse TeV gamma-ray emission from the southern supernova remnant, W28, and surrounding region. The search, made with the CANGAROO 3.8m telescope, encompasses a number

ZIF‐67‐Confined Pd Single‐Atom Catalysts Implanted Into Polydopamine‐Modified Bamboo Microchannels for Robust Continuous‐Flow Hydrogenation

open access: yesAdvanced Science, EarlyView.
The report presents a facile room‐temperature method to stabilize Pd single‐atom catalysts within ZIF‐67 crystals during their formation. Despite an ultralow Pd loading (0.0014 wt%), the catalytic microreactor, featuring atomically dispersed Pd‐N4 sites in ZIF‐67, demonstrates superior robustness and maximized Pd utilization, significantly ...

3D MC. II. X-Ray Echoes Reveal a Clumpy Molecular Cloud in the CMZ

open access: yesThe Astronomical Journal
X-ray observations collected over the past decades have revealed a strongly variable X-ray signal within the Milky Way’s Galactic center, interpreted as X-ray echoes from its supermassive black hole, Sgr A*.

Recent Advances in Decoupling Strategies for Soft Sensors

open access: yesAdvanced Science, EarlyView.
This review provides an overview of recent advances in decoupling strategies for soft sensors. It summarizes single‐modal sensors that are insensitive to stretching, bending, crosstalk, and other environmental interferences, and highlights emerging multimodal decoupling methods enabled by spatiotemporal information and machine learning.
