Constraints on stellar parameters of the SPB star HD182255 from complex asteroseismology
, 2012 Seismic modeling of the Slowly Pulsating B-type star HD182255 yields strong constraints on the radial orders of the two dominant modes. For these frequencies, we derive also the empirical values of the complex nonadiabatic parameter $f$.

Observing the very low-surface brightness dwarfs in a deep field in the VIRGO cluster: constraints on Dark Matter scenarios [PDF]
, 2017 We report the discovery of 11 very faint (r< 23), low surface brightness ({\mu}_r< 27 mag/arcsec^2) dwarf galaxies in one deep field in the Virgo cluster, obtained by the prime focus cameras (LBC) at the Large Binocular Telescope (LBT).

OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner
Plant Biotechnology Journal, EarlyView.ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...

Effects of solar‐simulated (UVB plus UVA) radiation on the skin microbiome: An exploratory study
Photochemistry and Photobiology, EarlyView.This exploratory in vivo study investigated the effects of solar‐simulated ultraviolet radiation (UVB plus UVA) on the human skin microbiome. Healthy male volunteers were exposed to suberythemal and erythemal UV doses, and skin microbiota were analyzed at multiple time points using flow cytometry‐based profiling and the open‐access bioinformatic ...
