The purpose of the present study was to determine the prevalence of antibiotic-resistant enterococci in dogs and cats subjected to differing antibiotic pressures, and the prevalence of vancomycin resistance genes in isolates from these animals. Enterococci were isolated from fecal samples of 65 healthy dogs and 29 healthy cats brought to animal hospitals,(More)
Circumstellar disks are usually formed around young stars and are intricately tied to the origin of planets (e.g., [1]). Giant planets have been considered to form via gas accretion onto rocky cores in such disks (e.g., [2]), which can successfully explain " normal " giant planets like ours. However, recent direct detections of companions with masses of a(More)
023 Protoplanetary disks are believed to be the birthplaces of planets [1]. Among them, disks which have substantial infrared excesses but reduced uxes at wavelengths < 20 µm, i.e., transitional disks [2], could be related to the early phases of planet formation [3] and are therefore particularly important for understanding how, where, and when planets(More)
We present the design, construction, and performance of TRISPEC (Triple Range Imager and Spectrograph), a simultaneous optical and near-infrared imager, spectrograph, and polarimeter. This instrument splits the incoming light from a telescope into the three beams—one optical channel (0.45–0.90 mm) and two infrared channels (0.90–1.85 and 1.85–2.5 mm)—by(More)
The formation process for stars with masses several times that of the Sun is still unclear. The two main theories are mergers of several low-mass young stellar objects, which requires a high stellar density, or mass accretion from circumstellar disks in the same way as low-mass stars are formed, accompanied by outflows during the process of gravitational(More)
Studies of the structure and evolution of protoplanetary disks are important for understanding star and planet formation. Here we present the direct image of an interacting binary protoplanetary system. Both circumprimary and circumsecondary disks are resolved in the near-infrared. There is a bridge of infrared emission connecting the two disks and a long(More)
We report the discovery of a very cool, isolated brown dwarf, UGPS 0722-05, with the UKIDSS Galactic Plane Survey. The near-infrared spectrum displays deeper H 2 O and CH 4 troughs than the coolest known T dwarfs and an unidentified absorption feature at 1.275 µm. We provisionally classify the object as a T10 dwarf but note that it may in future come to be(More)
