We report the synthesis of single-crystalline VO2 nanowires with rectangular cross sections using a vapor transport method. These nanowires have typical diameters of 60 (+/-30) nm and lengths up to >10 mum. Electron microscopy and diffraction measurements show that the VO2 nanowires are single crystalline and exhibit a monoclinic structure. Moreover, they preferentially grow along the [100] dir...

BACKGROUND 359 lung transplantations were performed in Germany in 2013. The main goals of lung transplantation are to prolong survival and improve the quality of life. Both of these goals can be reflected in a return to employment. We report the first study of employment after lung transplantation in Germany. METHODS We evaluated the findings of a single-center, questionnaire-based cross-sect...

The deep convolutional neural networks have achieved significant improvements in accuracy and speed for single image super-resolution. However, as the depth of network grows, the information flow is weakened and the training becomes harder and harder. On the other hand, most of the models adopt a single-stream structure with which integrating complementary contextual information under different...

The frequency conversion of light has proved to be a crucial technology for communication, spectroscopy, imaging, and signal processing. In the quantum regime, it also offers great potential for realizing quantum networks incorporating disparate physical systems and quantum-enhanced information processing over a large computational space. The frequency conversion of quantum light, such as singl...

We study 1s→2s(2p) excitation of hydrogen as a function of the nuclear charge of the projectile, ZP , for a fixed impact velocity, v51.3 a.u., for which electron excitation, capture, and ionization are competitive processes. For this purpose, we have performed large ab initio close-coupling calculations using a molecular basis in the framework of the impact-parameter method. Excitation probabil...

In smooth muscle, a cross-bridge mechanism is believed to be responsible for active force generation and fiber shortening. In the present studies, the viscoelastic and kinetic properties of the cross-bridge were probed by eliciting tension transients in response to small, rapid, step length changes (delta L = 0.3-1.0% Lcell in 2 ms). Tension transients were obtained in a single smooth muscle ce...

We derive threshold resummations for single-particle and single-jet inclusive cross sections, thus generalizing previous results at fixed invariant mass to a wider class of cross sections with phenomenological interest. We confirm the structure of our resummed expressions by comparison with explicit one-loop calculations for direct photons and heavy quarks.

Background: Multi-drug resistant (MDR) Citrobacter freundii (C. freundii) as a causative agent of nosocomial infections is a health threat, especially in hospitals. This study was conducted to determine the prevalence of MDR C. freundii, considering isolation sites and a variety of utilized antibiotics. Materials and Methods: In this cross-sectional study, the clinical samples of C. freundii s...

this study investigated the effect of sowing date and limited water allocation management for single irrigation on the grain yield of rainfed barley. the experiment was a split-split plot arranged in a randomized complete block design with three replications from 2004 to 2006 at the main station of the dryland agricultural research institute at maragheh. the treatments comprised three sowing da...

A stereophonic enhancement system is described which expands the perceived width of the stereo sound image. The system accepts electrical audio signals comprising a two-channel (left and right) stereo pair and produces enhanced left and right stereo signals for use with conventional two-channel audio recording and playback systems. The system includes control circuitry which monitors the dissim...
