We present an analysis of the accretion properties of the members of the TW Hydrae association. The emission line profile of Hα provides explicit evidence of an active accretion flow in 3 out of the 23 observed members of the association; we use radiative transfer models to derive approximate accretion rates for these 3 objects. The resulting accretion rates for the three 10 Myr-old objects (< ...

A graph is said to be chordal if each cycle with at least four vertices has a chord, that is an edge between two non-consecutive vertices of the cycle. Given an arbitrary graph G = (V, E), a triangulation of G is a chordal graph H(= V, F) such that E ⊆ F. We say that H is a minimal triangulation of G if no proper subgraph of H is a triangulation of G. The treewidth tw(H) of a chordal graph is i...

PURPOSE To report the four-year experience of the Stanford University Network for Diagnosis of Retinopathy of Prematurity (SUNDROP) telemedicine initiative, which was developed to reduce the risk of blindness from retinopathy of prematurity (ROP). MATERIALS AND METHODS A retrospective analysis of the SUNDROP archival data between 12/1/2005 and 11/30/2009. A total of 410 consecutively enrolled...

Impacts of urban land use can include increased stormwater runoff temperature (Tw) leading to receiving water quality impairment. There is therefore a need to target and mitigate sources of thermal pollution in urban areas. However, complex relationships between urban development, stormwater runoff and stream water heating processes are poorly understood. A nested-scale experimental watershed s...

On decreasing the temperature T , supercooled water and other tetrahedral network-forming liquids, such as BeF2 or SiO2, appear to display a dynamic crossover from non-Arrhenius dynamics (with T -dependent activation energy) to Arrhenius dynamics (with constant activation energy). Simulations for water models show that this crossover occurs on crossing the Widom line TW (P ), the locus of maxim...

This study was conducted to determine changes for some quality characters in M2, M3 and M4 mutated populations of three bread wheat genotypes irradiated by different gamma rays. The results showed that the significantly variably differed their response various traits at rays doses M3, populations. shifts per see from controls examined such as thousand-grain weight (TGW), test (TW), wet gluten c...

This work investigates the scaled height distribution, ρ(q), of irregular profiles that are grown based on two sets of local rules: those of the restricted solid on solid (RSOS) and ballistic deposition (BD) models. At each time step, these rules are respectively chosen with probability p and r=1-p. Large-scale Monte Carlo simulations indicate that the system behaves differently in three succee...

The influence of the tibial tuberosity conformation on cranial cruciate ligament (CrCl) rupture was evaluated and the size of the tibial tuberosity of healthy dogs (group H) was compared with dogs with CrCl rupture (group R) and dogs treated by tibial tuberosity advancement (TTA) (group T). The medio-lateral radiographs of 219 stifle joints were evaluated. Relative tibial tuberosity width (rTTW...
