Selected astrometric catalogues [PDF]

arXiv, 2017
A selection of astrometric catalogues are presented in three tables for respectively positions, proper motions and trigonometric parallaxes. The tables contain characteristics of each catalogue showing the evolution in optical astrometry, in fact the evolution during the past 2000 years for positions. The number of stars and the accuracy are summarized

Mining the UKIDSS GPS: star formation and embedded clusters

, 2012
Data mining techniques must be developed and applied to analyse the large public data bases containing hundreds to thousands of millions entries. The aim of this study is to develop methods for locating previously unknown stellar clusters from the UKIDSS

Immunosuppressive Formulations for Immunological Defense against Traumatic Brain Injury

Advanced Healthcare Materials, EarlyView.
A novel subcutaneous formulation combining alpha‐ketoglutarate, glycolysis inhibitor PFK15, and a myelin peptide reduces inflammation in a mouse TBI model. This formulation promotes regulatory immune cells, enhances autophagy, and improves motor function, suggesting its potential as a prophylactic immunosuppressive therapy to mitigate TBI‐induced ...

The Star Catalogue of Hevelius

, 2010
The catalogue by Johannes Hevelius with the positions and magnitudes of 1564 entries was published by his wife Elisabeth Koopman in 1690. We provide a machine-readable version of the catalogue, and briefly discuss its accuracy on the basis of comparison ...

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

Advanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Validation of the new Hipparcos reduction

, 2007
Context.A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming accuracies for nearly all stars brighter than magnitude Hp = 8 to be better, by up to a factor 4, than in the original catalogue.

Biomimetic Dynamics of Nanoscale Groove and Ridge Topography for Stem Cell Regulation

Advanced Materials, EarlyView.
Dynamic nanoscale groove‐ridge structures are engineered by flexibly conjugating RGD‐magnetic nanoparticles to nanogroove templates with variable groove widths at the molecular scale. Magnetic control enables cyclic switching between nanoscale groove and ridge states that modulates ligand accessibility of cellular integrins.

Design of a Simple and Rugged Soft Polydimethylsiloxane‐Carbon Nanotube‐Graphene‐Based Composite Sensor

Advanced Materials Technologies, EarlyView.
This research presents an easy to fabricate, low‐cost, flexible piezoresistive deformation sensor comprised of a carbon nanotube, few‐layer graphene, and polydimethylsiloxane composite. The sensor detects deformations and vibrations up to 600 Hz with 0.1% strain sensitivity from stiff and soft targets in dry and wet environments.
