Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

ПЕРВЫЕ РЕЗУЛЬТАТЫ ДЕКАМЕТРОВОГО ОБЗОРА СЕВЕРНОГО НЕБА. РЕДЕТЕКТИРОВАНИЕ ИЗВЕСТНЫХ ПУЛЬСАРОВ

open access: yesOdessa Astronomical Publications, 2011
At the UTR-2 radio telescope the survey of northern sky is being conducted with aim to search for pulsars and transients. In the first stage the detection of a complete list of known pulsars with parameters DM -3, period more than 0.1 s and declination ...

Probing gravitation with pulsars

open access: yes, 2012
Radio pulsars are fascinating and extremely useful objects. Despite our on-going difficulties in understanding the details of their emission physics, they can be used as precise cosmic clocks in a wide-range of experiments -- in particular for probing ...

Soybean Inositol Polyphosphate 5‐Phosphatase 8 Confers Salt Tolerance by Reducing Sodium Influx Through Inositol 1,4,5‐Trisphosphate Signalling

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Evidence suggests that the metabolism of inositol and its derivatives may be involved in various biological processes including salt tolerance, but there has been limited understanding. Ectopic expression of Gs5PTase8, an inositol polyphosphate 5‐phosphatase cloned from wild soybean (Glycine soja), significantly enhanced salt tolerance in ...

A Census of Pulsars in Possible Association with Galactic Open Clusters

open access: yesThe Astrophysical Journal Letters
Among the ∼4000 known pulsars in our Galaxy, ≲10% are found in globular clusters, but none has been confirmed in any open clusters yet, although they outnumber globular clusters by about 20 times.

A Search for Pulsars around Sgr A* in the First Event Horizon Telescope Data Set

open access: yesThe Astrophysical Journal, 2023
In 2017 the Event Horizon Telescope (EHT) observed the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), at a frequency of 228.1 GHz ( λ = 1.3 mm).

Discovery of 28 pulsars using new techniques for sorting pulsar candidates

open access: yes, 2009
Modern pulsar surveys produce many millions of candidate pulsars, far more than can be individually inspected. Traditional methods for filtering these candidates, based upon the signal-to-noise ratio of the detection, cannot easily distinguish between ...

TMEM16A channel signalling microdomains in the regulation of vascular function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Modeling the Radial Distribution of Pulsars in the Galaxy

open access: yesThe Astrophysical Journal Letters
The Parkes 20 cm multibeam pulsar surveys have discovered nearly half of the known pulsars and revealed many distant pulsars with high dispersion measures.
