Two-zone model for the broadband Crab nebula spectrum: microscopic interpretation
EPJ Web of Conferences, 2017 We develop a simple two-zone interpretation of the broadband baseline Crab nebula spectrum between 10−5 eV and ~ 100 TeV by using two distinct log-parabola energetic electrons distributions.

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction
Advanced Science, EarlyView.During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

Large-scale Field-aligned Flows in the Heliosheath
The Astrophysical JournalWe use a state-of-the-art 3D MHD simulation to show that large-scale thermal pressure gradients in the heliosheath drive suprathermal particles (pickup ions with 1–5 keV) to stream along magnetic field lines faster than the cold bulk solar wind.

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis
Advanced Science, EarlyView.In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.

Connexin 43‐Enriched Vesicles Improve Synchronization in hiPSC‐Derived Cardiomyocytes
Advanced Science, EarlyView.Plasma membrane‐derived Connectosomes enriched in connexin‐43 are produced from donor hiPSCs and applied to hiPSC‐derived cardiomyocytes (hiPSC‐CMs). Connexin‐43 channels on Connectosomes remain functional, strengthening intercellular electrochemical coupling and increasing network synchronization over time.

Do Anomalous Cosmic Rays Modify the Termination Shock? [PDF]
, 2004 This work extends our previous two-dimensional self-consistent model of the cosmic rays interacting with the solar wind to include anomalous cosmic rays. As before, energetic particles are described kinetically using a Parker equation. The model includes

Advanced Science, EarlyView.HNRNPD promotes radioresistance in nasopharyngeal carcinoma by enhancing stress granule assembly and sequestering GRAMD4 mRNA. This suppresses GRAMD4 translation and inhibits mitochondrial apoptosis. Targeting the integrated stress response with ISRIB restores GRAMD4 expression and sensitizes tumors to radiotherapy, revealing a translational control ...

The Gradual Slowing of the Solar Wind in the Outer Heliosphere
The Astrophysical JournalThe solar wind gradually slows with increasing distance from the Sun as interstellar material becomes ionized and picked up by the solar wind. When observing the solar wind in the outer heliosphere, it is difficult to differentiate temporal decreases in ...

Mapping the “Supply–Demand–Flow” of Ecosystem Services for Ecosystem Management in China
Advanced Science, EarlyView.This study develops a “supply–demand–flow” framework clarifies how ecosystem services move between regions by distinguishing potential and actual supply and demand. Using integrated biophysical–socioeconomic modeling, nine services in China were mapped.

Termination shock response to large-scale solar wind fluctuations
, 1994 The analysis of data recorded by the Voyager 2 spacecraft indicates the presence of large-scale fluctuations in the solar wind ram pressure on the time scale of tens of days.
