Advanced Materials Technologies, EarlyView.Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

The distance of M33 and the stellar population in its outskirts
, 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 ...

Asteroseismology of red-clump stars with CoRoT and Kepler [PDF]
, 2009 The availability of asteroseismic constraints for a large number of red giants with CoRoT and in the near future with Kepler, paves the way for detailed studies of populations of galactic-disk red giants.

Advanced Science, EarlyView.In this study, we provided new evidence identifying multinucleated cysts as precursors for oocyte differentiation. Within these cysts, organelles migrate and aggregate to form Balbiani body (B‐body) and establish early cellular polarity. Concurrently, excess nuclei are expelled, enabling cyst‐to‐oocyte differentiation. The microfilament‐myosin II plays

Evolutionary and Observational Properties of Red Giant Acoustic Glitch Signatures
The Astrophysical Journal, 2023 While solar-like oscillations in red giants have been observed at massive scales by the Kepler mission, few features of these oscillation mode frequencies, other than their global properties, have been exploited for stellar characterization.

Hubble Space Telescope Photometry of the Dwarf Spheroidal Galaxy ESO 410-G005 [PDF]
, 2000 We present HST WFPC2 imaging of the nearby low-surface-brightness dwarf spheroidal galaxy ESO 410-G005, which has been resolved into stars for the first time. The resulting color-magnitude diagram for about 2500 stars shows a red giant branch branch with

The Tip of the Red Giant Branch Distance to the Large Magellanic Cloud [PDF]
The Astronomical Journal, 2000 We present the I-band luminosity function of the red giant branch stars in the Large Magellanic Cloud (LMC) using the data from the Magellanic Clouds Photometric Survey (Zaritsky, Harris & Thompson, 1997). Selecting stars in uncrowded, low-extinction regions, a discontinuity in the luminosity function is observed at I_0 = 14.54 mag.

Advanced Science, EarlyView.A novel multifunctional scaffold with photothermal effects is developed for infected bone defect repair. It facilitates angiogenesis and osteogenesis while eliminating bacteria through hyperthermia. Additionally, the scaffold promotes macrophage polarization from M1 to M2 via ROS scavenging, enhancing anti‐inflammatory activity. This study demonstrates
