Observation by the CANGAROO-III stereoscopic system of the Imaging Cherenkov Telescope has detected extended emission of TeV gamma rays in the vicinity of the pulsar PSR B1706−44. The strength of the signal observed as gamma-ray-like events varies when we apply different ways of emulating background events. The reason for such uncertainties is argued in relevance to gamma-rays embedded in the “...

We experimentally realize a compact wideband polarization splitter and rotator (PSR) with CMOS compatibility. The fabricated PSR is then tested by utilizing a fabrication-tolerant TE-pass on-chip polarizer we propose to practically solve the issue of accurately aligning the polarizations in fiber and modes on chip. Both of these polarization handling devices take the advantage of bend structure...

We propose a compact highly-efficient CMOS-compatible polarization splitter and rotator (PSR) with a wide bandwidth covering the whole O-band. It benefits from the different confinement capability of TE and TM modes in bend structure. This bend structure helps shorten the PSR and maintain high efficiency, achieving the bending, polarization splitting, rotating of light beam at the same time. Nu...

− This paper describes a control architecture design and a system integration strategy for the autonomous service robot PSR(Public Service Robot). The PSR is under development at the KIST(Korea Institute of Science and Technology) for service tasks in public spaces such as office buildings and hospitals. The proposed control architecture is designed by tripodal frameworks, which are layered fun...

This paper introduces a simple new measure of innovation, the patent success ratio (PSR), namely the ratio of successful patent applications to total patent applications. It has been argued in the extensive literature on innovation and technology policy that patents can serve as an accurate proxy for innovative activity. This paper suggests that PSR is a more accurate measure of how innovative ...

The five millisecond pulsars that inhabit NGC 6752 display locations or accelerations remarkably different with respect to all other pulsars known in globular clusters. This may reflect the occurrence of an uncommon dynamics in the cluster core that could be attributed to the presence of a massive perturber. We here investigate whether a single intermediatemass black hole, lying on the extrapol...

The rotation-powered pulsar PSR J1846−0258 in the supernova remnant Kes 75 was recently shown to have exhibited magnetar-like X-ray bursts in mid2006. Radio emission has not yet been observed from this source, but other magnetar-like sources have exhibited transient radio emission following X-ray bursts. We report on a deep 1.9 GHz radio observation of PSR J1846−0258 with the 100-m Green Bank T...

We have investigated the radio polarization properties of PSR J1119 6127, a recently discovered young radio pulsar with a large magnetic field. Using pulsar-gated radio imaging data taken at a center frequency of 2496 MHz with the Australia Telescope Compact Array, we have determined a rotation measure for the pulsar of +842 23 rad m 2. These data, combined with archival polarimetry data taken ...

One of the cellular defensivemechanisms against proteotoxic stress is the evolutionarily conserved proteotoxic stress response (PSR) or heat-shock response (HSR). Through up-regulation of molecular chaperones or heat-shock proteins (HSPs), the PSR empowers cells to repair and/or dispose of misfolded and aggregated proteins, thereby enduring stressful environments. Beyond being vital to stress r...

We report on deep VLT observations of the fields of two nearby, isolated millisecond pulsars PSR J1744-1134 and PSR J1024-0719. Both objects are old neutron stars with characteristic age τ ≥ 10 yr and have relatively high spin-down flux. They have been detected earlier as X-ray sources by ROSAT HRI observations and were considered good candidates for non-thermal emission in the optical bands. O...
