Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Long photometric cycles in hot algols [PDF]
Serbian Astronomical Journal, 2017 We summarize the development of the field of Double Periodic Variables (DPVs, Mennickent et al. 2003) during the last fourteen years, placing these objects in the context of intermediate-mass close interacting binaries similar to β Persei (Algol)

Bayesian bulge–disc decomposition of galaxy images [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We introduce PHI, a fully Bayesian Markov-chain Monte Carlo algorithm designed for the structural decomposition of galaxy images. PHI uses a triple layer approach to effectively and efficiently explore the complex parameter space. Combining this with the use of priors to prevent nonphysical models, PHI offers a number of significant advantages for ...

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields
Advanced Science, EarlyView.Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

РЕНТГЕНОВСКОЕ ИЗЛУЧЕНИЕ ГАЛАКТИК БЕЗ АКТИВНЫХ ЯДЕР
Odessa Astronomical Publications, 2011 We perfirmed cross-correlation of SDSS galaxies and X-ray sources from 2XMMi catalogue. We selected galaxies with strong NII[6583] and OIII[5007] lines to divide them to starburst galaxies and AGNs.

Wakes of ram-pressure-stripped disc galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 Spiral galaxies that move through the intracluster medium lose a substantial amount of their gas discs due to ram pressure stripping. The recent observations of NGC 4388 by Oosterloo & van Gorkom 2005 reveal a tail of stripped gas of ~ 100 kpc behind the source galaxy.

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring
Advanced Science, EarlyView.Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Constraining the formation of the Milky Way: Ages
EPJ Web of Conferences, 2013 We present a new approach for studying the chemodynamical evolution of the Milky Way, which combines a thin disk chemical evolution model with the dynamics from N-body simulation of a galaxy with properties similar to those of our Galaxy.

SOME PECULIARITIES OF THE RADIAL GAS DISTRIBUTION IN GALACTIC DISC
Odessa Astronomical Publications, 2017 This paper reports on the theoretical investigation of evolution of the Galaxy. The spiral arms and radial gas flows can be considered as some kind of indicators of the dynamical processes in the disc. Investigation the surface density of gas.
