We present a phase-connected timing solution for the nearby isolated neutron star RX J1308.6+2127 (RBS 1223). From dedicated Chandra observations as well as archival Chandra and XMM-Newton data spanning a period of five years, we demonstrate that the 10.31-sec pulsations are slowing down steadily at a rate of Ṗ = 1.120(3)× 10 s s. Under the assumption that this is due to magnetic dipole torques...

PURPOSE To evaluate in vitro the capture efficiency of a distal protection filter (DPF) used during carotid artery stenting and examine the longitudinal vascular impedance in the presence of a DPF. METHODS Four approved DPFs (Spider RX, FilterWire EZ, RX Accunet, and FiberNet) were evaluated in a physiologically realistic in vitro setup. A pulsatile programmable piston pump circulated a blood...

The fields of 8 X-ray sources in the Magellanic Clouds believed to be Be/X-ray binaries have been searched for possible Be star counterparts. BV Rc and Hα CCD imaging was employed to identify early type emission stars through colour indices and Hα fluxes. Spectroscopy of 5 sources confirms the presence of Hα emission in each case. Based on the positional coincidence of emission line objects wit...

In broadband single-carrier (SC) multi-user multipleinput multiple-output (MU-MIMO) transmissions, inter-symbol interference (ISI) caused by frequency-selectivity of the channel, inter-antenna interference (IAI), and inter-user interference (IUI) degrade the transmission quality. This paper proposes a minimum mean square error based joint transmit and receive linear spatial/frequency filtering ...

Vertebrate and invertebrate eye development require the activity of several evolutionarily conserved genes. Among these the Pax-6 genes play a major role in the genetic control of eye development. Mutations in Pax-6 genes affect eye development in humans, mice, and Drosophila, and misexpression of Pax-6 genes in Drosophila can induce ectopic eyes. Here we report the identification of a paired-l...

Abstract Using recently installed scrape-off layer diagnostics on the tokamak à configuration variable, we characterise poloidal and parallel properties of turbulent filaments. We access both attached detached divertor conditions across a wide range core densities ( f G ? [0.09, 0.66]) in diverted L-mode plasma configurations. With gas puff imaging (GPI) diagnostic at outer midplane observed fi...

Purpose: The Nova 7 T RF coil, which has single-channel transmission (TX) [1] and 24 or 32 channel reception (RX) [2,3] (Nova Medical, Wilmington, MA) is notable for its excellent signal to noise (SNR) performance. The coil designers have demonstrated that separate dedicated coils for transmission and reception (TX-only, RX-only) perform better than a combined-element transceiver coil. One disa...

Genes encoding plant nucleotide-binding leucine-rich repeat (NB-LRR) proteins confer dominant resistance to diverse pathogens. The wild-type potato NB-LRR protein Rx confers resistance against a single strain of potato virus X (PVX), whereas LRR mutants protect against both a second PVX strain and the distantly related poplar mosaic virus (PopMV). In one of the Rx mutants there was a cost to th...

We present RXTE observations of two recently identified massive X-ray binaries. RX J0440.9+4431/BSD 24–491 and RX J1037.5–564/LS 1698 are confirmed as accreting Be/X-ray systems following the discovery of X-ray pulsations, with barycentric pulse periods of 202.5±0.5 s and 860±2 s respectively. The X-ray spectral analysis shows that the energy spectra of the pulsars can be represented by a power...
