KÜRESEL KONUM BELİRLEME SİSTEMİ (GPS) ve COĞRAFYA ARAŞTIRMALARINDA KULLANIMI

open access: yesCoğrafi Bilimler Dergisi, 2005
NAVSTAR-GPS has the widest usage and the largest number of users among the satellites for the purpose of determining location, recently. The basis of this system relies on the first satellite system for determining location, Navy Navigation Satellite ...

Transit Light Curves with Finite Integration Time: Fisher Information Analysis [PDF]

open access: yes, 2014
Kepler has revolutionized the study of transiting planets with its unprecedented photometric precision on more than 150,000 target stars. Most of the transiting planet candidates detected by Kepler have been observed as long-cadence targets with 30 ...

Intestinal function and transit associate with gut microbiota dysbiosis in cystic fibrosis

open access: yesmedRxiv, 2021
Background: Most people with cystic fibrosis (pwCF) suffer from gastrointestinal symptoms and are at risk of gut complications. Gut microbiota dysbiosis is apparent within the CF population across all age groups, with evidence linking dysbiosis to ...

NEMESIS: Exoplanet Transit Survey of Nearby M-dwarfs in TESS FFIs. I. [PDF]

open access: yesAstronomical Journal, 2021
In this work, we present an analysis of 33,054 M-dwarf stars, located within 100 parsecs, via the Transiting Exoplanet Survey Satellite (TESS) full-frame images (FFIs) of observed sectors 1–5.

Kepler Transit Depths Contaminated by a Phantom Star [PDF]

open access: yes, 2016
We present ground-based observations from the Discovery Channel Telescope (DCT) of three transits of Kepler-445c---a supposed super-Earth exoplanet with properties resembling GJ 1214b---and demonstrate that the transit depth is approximately 50 percent ...

Characterizing K2 planet discoveries : a super-Earth transiting the bright K dwarf HIP 116454 [PDF]

open access: yes, 2014
We report the first planet discovery from the two-wheeled Kepler (K2) mission: HIP 116454 b. The host star HIP 116454 is a bright (V = 10.1, K = 8.0) K1 dwarf with high proper motion and a parallax-based distance of 55.2 ± 5.4 pc.

Transiently Active Wnt/β-Catenin Signaling Is Not Required but Must Be Silenced for Stem Cell Function during Muscle Regeneration

open access: yesStem Cell Reports, 2014
Adult muscle’s exceptional capacity for regeneration is mediated by muscle stem cells, termed satellite cells. As with many stem cells, Wnt/β-catenin signaling has been proposed to be critical in satellite cells during regeneration.

Phase transitions and convection in Icy satellites

open access: yesGeophysical Research Letters, 1986
The effects of solid‐solid phase changes on subsolidus convection in the large icy moons of the outer solar system are considered. Phase transitions affect convection via processes that distort the phase change boundary and/or influence buoyancy through thermal expansion.

Dark Transit of Jupiter's First Satellite [PDF]

open access: yesNature, 1884
ON May 18, at 8h., on observing Jupiter with my 10-inch reflector, p. 252, I saw three very dark spots—one near the planet's centre, and two others not far advanced upon the east limb. These I took to be the shadows of satellites, and on reference found that the shadows of Satellites I. and II. were really upon the planet; also Satellite I. itself. The
