The distance of M33 and the stellar population in its outskirts

open access: yes, 2004
We present deep V,I photometry of two $9.4' x 9.4' field in the outer regions of the M33 galaxy. We obtain a robust detection of the luminosity of the Red Giant Branch Tip (I{TRGB}=20.72 +- 0.08) from which we derived a new estimate of the distance ...

Iodine‐Doped Sodium Vanadate Cathode for Improved Zn Ion Diffusion Kinetics

open access: yesAdvanced Materials, EarlyView.
An iodine‐doping strategy is developed to modify the Na2V6O16·3H2O cathode for aqueous zinc‐ion batteries, effectively reducing the electrostatic interaction between zinc ions and the host structure. This modification enables faster diffusion and higher storage capacity of zinc ions. Abstract The electrostatic interaction between zinc ions and the host

Revealing the Fate of Exoplanet Systems: Asteroseismic Identification of Host Star in the Red Clump or Red Giant Branch

open access: yesThe Astrophysical Journal Letters
Determining the evolutionary stage of stars is crucial for understanding the evolution of exoplanetary systems. In this context, red giant branch (RGB) and red clump (RC) stars, which formed at stages in the later evolution of stars situated before and ...

A case of giant condyloma latum in vulvar and perianal areas [PDF]

open access: yesXin yixue
Condyloma latum is a typical lesion of secondary syphilis,which usually appears in the vicinity of the initial chancre. It is found that treponema pallidum load in condyloma latum is significantly higher than that in other secondary syphilis. We report a

Intertwined Topological Phases in TaAs2 Nanowires with Giant Magnetoresistance and Quantum Coherent Surface Transport

open access: yesAdvanced Materials, EarlyView.
Synthesis of topological semimetal TaAs2 nanowires in situ encapsulated with a thin SiO2 shell unravel a richness of intertwined topological phases manifested by their magnetotransport features: A near‐room‐temperature metal‐to‐insulator transition, strong expressions of topologically nontrivial surface transport, giant magnetoresistance with direction‐
