The local power law relationship between the surface densities of neutral hydrogen gas and star formation rate (SFR) can be used to explore the SFR properties of damped Lyman α (DLA) systems at higher redshift. We find that while the SFR densities for DLA systems are consistent with luminous star forming galaxies at redshifts below z ≈ 0.6, at higher redshifts their SFR density is too low for t...
This study was conducted to generate and validate a cross-culturally adapted Korean version of the xerostomia inventory (XI), an 11-item questionnaire designed to measure the severity of xerostomia. The original English version of the XI was translated into Korean according to the guidelines for cross-cultural adaptation of health-related quality-of-life measures. Among a prospective cohort of ...
Using a simple model of molecular cloud evolution, we have quantitatively estimated the change of star formation rate (SFR) of a disk galaxy falling radially into the potential well of a cluster of galaxies. The SFR is affected by the ram-pressure from the intracluster medium (ICM). As the galaxy approaches the cluster center, the SFR increases to twice the initial value, at most, in a cluster ...
Urinary stone is a worldwide disease and percutaneous nephrolithotomy (PCNL) is the most commonly used operation for staghorn calculi. Research indicated that SFR for staghorn calculi in one stage of PCNL showed 50%-91% results, under standard operation, standard instrument and professional treatment route. The present study aimed to explore the clinical factors of stone free rates (SFR) after ...
We measure the evolution of the [O II] λ3727 luminosity function at 0.75 < z < 1.45 using highresolution spectroscopy of ∼ 14, 000 galaxies observed by the DEEP2 galaxy redshift survey. We find that brighter than L[OII] = 10 42 erg s the luminosity function is well-represented by a power law dN/dL ∝ L with slope α ∼ −3. The number density of [O II]-emitting galaxies above this luminosity declin...
The evolution of the galaxy stellar mass–star formation rate relationship (M∗−SFR) provides key constraints on the stellar mass assembly histories of galaxies. For star-forming galaxies, M∗−SFR is observed to be fairly tight with a slope close to unity from z ∼ 0 → 2, and it evolves downwards roughly independently of M∗. Simulations of galaxy formation reproduce these trends, broadly independen...

There has been plenty of observational evidence of cluster galaxy evolution such as the Butcher-Oemler effect and the decrease in S0 fraction with increasing redshift. As a modern version, the redshift evolution of total star formation rate (SFR) in clusters has been actively debated recently. However, these studies of redshift trend have been always hampered by the possible mass dependence; du...
INTRODUCTION The myocardial response to acute stretch consists of a two-phase increase in contractility: an acute increase by the Frank-Starling mechanism and a gradual and time-dependent increase in force generated known as the slow force response (SFR). The SFR is actively modulated by different signaling pathways, but the role of protein kinase G (PKG) signaling is unknown. In this study we ...
The merging cluster of galaxies A2255 is covered by the Sloan Digital Sky Survey (SDSS) survey. The physical parameters of 184 bright member galaxies derived from the SDSS data analyses by Brinchmann et al. (2004b) allow a detailed study on the star formation properties of the galaxies within a merging cluster at intermediate redshift. In this paper we perform a morphological classification on ...
