Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

Advanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Follow-up Observations of the Second and Third Known Pulsating Hot DQ White Dwarfs

, 2009
We present follow-up time-series photometric observations that confirm and extend the results of the significant discovery made by Barlow et al.(2008) that the Hot DQ white dwarfs SDSS J220029.08-074121.5 and SDSS J234843.30-094245.3 are luminosity ...

Hepatoma‐Derived Growth Factor Coordinates STAT3 Pathway and Exosome‐Mediated Intrahepatic Crosstalk to Control Hepatic Steatosis and MASLD

Advanced Science, EarlyView.
Hepatic HDGF as a key mediator in coordinating hepatic steatosis and intrahepatic crosstalk in MASLD. Activation of HDGF facilitates its interaction with both STAT3 and S6K1, driving the S6K1‐dependent STAT3 phosphorylation and subsequently enhancing hepatic lipogenesis.

A Multiple-detection-heads Machine Learning Algorithm for Detecting White Dwarfs

The Astrophysical Journal Supplement Series
White dwarfs (WDs) are the ultimate stage for approximately 97% of stars in the Milky Way and are crucial for studying stellar evolution and galaxy structure. Due to their small size and low luminosity, WDs are not easily observable.

Redox‐Active Tungsten Mono‐Oxo Bis(dithiolene) Complex: A Fast‐Rechargeable Anode for High‐Capacity Lithium‐Ion Batteries

Advanced Science, EarlyView.
This study reports the first application of a W‐oxo bis(dithiolene) complex, (Et4N)2[WO(S2C2(C6H5)2)2], as a novel anode material for lithium‐ion batteries. This complex stores Li+ ions via multivalent W‐centered redox processes involving its oxo (WO) and dithiolene (S) sites.

Highly Robust Sn‐Based MAX Anodes Constructed via Ti6C Octahedral Outer Immobilization and A‐Layer Fe Inner Anchoring for Long‐Life Lithium‐Ion Batteries

Advanced Science, EarlyView.
How can Sn‐based anodes achieve high capacity and long‐life cycling? This work unlocks the potential anode structure by confining Sn in the A layer of MAX phase with Ti6C octahedra as outer immobilization and Fe as inner anchors. The introduction of Fe dramatically strengthens the Ti–Sn bond to enhance structural integrity, modulate interfacial ...

Coordinated Space- and Ground-based Monitoring of Accretion Bursts in a Protoplanetary Disk: Establishing Mid-infrared Hydrogen Lines as Accretion Diagnostics for JWST/MIRI

The Astrophysical Journal
In this paper, we establish and calibrate mid-infrared (MIR) hydrogen recombination lines observed with the James Webb Space Telescope as accretion tracers for pre-main-sequence stars that accrete from circumstellar disks.

Superhumps in Cataclysmic Binaries. XXIII. V442 Ophiuchi and RX J1643.7+3402

, 2002
We report the results of long observing campaigns on two novalike variables: V442 Ophiuchi and RX J1643.7+3402. These stars have high-excitation spectra, complex line profiles signifying mass loss at particular orbital phases, and similar orbital periods
