The Milky Way and its gas: Cold fountains and accretion
EPJ Web of Conferences, 2012 The Milky Way is acquiring gas from infalling high-velocity clouds. The material enters a disk-halo interface that in many places is populated with HI clouds that have been ejected from the disk through processes linked to star formation. The Smith Cloud

Particle &Particle Systems Characterization, EarlyView.This review explores improved tetracycline (TCN) delivery via polymer‐based nanocarriers to enhance solubility, stability, and targeted release. It also covers stimuli‐responsive systems, triggered by pH, enzymes, or reactive oxygen species (ROS), and co‐delivery approaches that increase therapeutic efficacy in cancer and inflammatory diseases ...

Radial Wave in the Galactic Disk: New Clues to Discriminate Different Perturbations
The Astrophysical JournalDecoding the key dynamical processes that shape the Galactic disk structure is crucial for reconstructing the Milky Way’s evolution history. The second Gaia data release unveils a novel wave pattern in the L _Z −〈 V _R 〉 space, but its formation ...

Asymmetric Mean Metallicity Distribution of the Milky Way’s Disk [PDF]
The Astrophysical Journal Letters, 2019 Abstract I present the mean metallicity distribution of stars in the Milky Way based on photometry from the Sloan Digital Sky Survey. I utilize an empirically calibrated set of stellar isochrones developed in previous work to estimate the metallicities of individual stars to a precision of 0.2 dex for reasonably bright stars across the ...

Small Science, EarlyView.Nanotopography improves the piezoelectric properties of BaTiO3 due to decreased Young's modulus. Nanotopography‐mediated mechanical stress dominantly boosts osteogenesis and angiogenesis via Piezo2/Piezo1/Ca2+ signaling. Augmented electric stimulation improves mechanical stress‐mediated osteogenic/angiogenic enhancement via PI3K/AKT/mTOR/GSK3β‐1 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Methods in Ecology and Evolution, EarlyView.Abstract The impact of flow on aquatic organisms (and vice versa) is crucial for many aspects of their physiology and ecology, as this interaction shapes the hydrodynamic boundary layer and thereby the exchange of solutes between the organism and its surrounding environment.

Annals of Applied Biology, EarlyView.Triticale and lupin are promising candidates for sustainable intercropping in low‐input, mixed crop–livestock farming systems in the Mediterranean basin, where they can be grown as rain‐fed crops during the autumn‐winter period. A field trial conducted in Sardinia demonstrated several key findings: the slower canopy development and shorter stature of ...
