We present an analysis of the environmental dependence of bars and bulges in disc galaxies, using a volume-limited catalogue of 15 810 galaxies at z < 0.06 from the Sloan Digital Sky Survey with visual morphologies from the Galaxy Zoo 2 project. We find that the likelihood of having a bar, or bulge, in disc galaxies increases when the galaxies have redder (optical) colours and larger stellar ma...

Bin-Amphiphysin-Rvs (BAR) domain proteins play essential roles in diverse cellular processes by inducing membrane invaginations or membrane protrusions. Among the BAR superfamily, the `classical' BAR and Fes/CIP4 homology BAR (F-BAR) subfamilies of proteins usually promote membrane invaginations, whereas the inverse BAR (I-BAR) subfamily generally incur membrane protrusions. Despite possessing ...

The distribution of novae across the face of the Large Magellanic Cloud (LMC) is presented. The star formation history of nearby regions around them is also studied using photometric data of stars and star clusters in the OGLE II survey and star cluster catalogues. The nova population in the LMC belong, predominantly, to the fast category, with only 11.8% belonging to the slow nova population. ...

We study the molecular environment, the onset of starbursts, and secular evolution in the circumnuclear (inner 1–2 kpc) region of barred galaxies using a carefully selected sample of barred non-starbursts and starbursts, along with a panchromatic dataset made of high resolution CO (J=1–0) observations, optical, NIR, Hα, radio continuum, Brγ, and archival HST data. (1) We find that the molecular...

The point-defect structure of monoclinic HfO2 (m-HfO2) was studied by means equilibrium electrical conductance measurements as a function temperature 1050≤T/K≤1200 and oxygen partial pressure −20≤log(pO2/bar)≤−2. total conductivity σ displayed similar behavior at each examined. In oxidizing conditions (pO2≥10−7bar), the increased with increasing assigned to hole conduction. Around 10−10 bar, re...

A laser-diode bar incorporated into an external cavity with a volume Bragg mirror produced 30 W of cw output power within a 20 pm (10 GHz) spectral linewidth (FWHM) centered at 780 nm. The device output power exceeded 90% of that for the free-running laser-diode bar. The emission wavelength was tuned over a 400 pm range without broadening laser spectrum width. Absorption of 90% of the laser rad...

We report a case of sternal reconstruction using bilateral sternal bar turnover flaps in a 4-year-old boy with an inferior sternal cleft, as part of Cantrell's pentad. When the patient was 10 months old, he underwent sternal reconstruction using a resorbable poly-L-lactic-polyglycolic acid plate in the first stage when there was insufficient autogenous tissue to provide a reliable reconstructio...

Psilorhynchus kaladanensis, a new psilorhynchid, is described from the Kaladan basin of Mizoram, India. The new species is diagnosed by having the following combination of characters: caudal fin with small but distinct dark brown triangular spot at mid-base, slightly elongated dark mark near base of lower lobe, indistinct V-shaped vertical bar across center, dark brown oblique bar across fin an...

This paper describes a case-study which illustrates the capabilities of a commercially available software package called SyMech, which runs within Pro/ENGINEER. The software allows a designer to synthesize arbitrarily complex planar mechanisms by sequentially specifying one of three basic mechanism design functions: position, path, or angle. Because the software runs directly within Pro/ENGINEE...
