We developed an adaptive polarimetric target detector (APTD) to determine the optimum combination strategy for a multichannel polarization-sensitive optical system. The proposed algorithm is based on scene-derived polarization properties of the target and background, and it seeks to find an optimum multichannel combination of linear polarizing filters that maximizes the signal-to-clutter ratio ...

Actins are small globular filaments functioning in cell processes like muscle contraction, and stabilized to the sarcomeric Z- discs by actin binding proteins (actinins). One of the important gene coding for actin binding proteins in fast twitch fibers is alpha- actinin- 3 (ACTN3). In this research, we have conducted a gene profile study investigating the genotype and allele distributions of AC...

Hyperspectral sensors are passive sensors that simultaneously record images for hundreds of contiguous and narrowly spaced regions of the electromagnetic spectrum. Each image corresponds to the same ground scene, thus creating a cube of images that contain both spatial and spectral information about the objects and backgrounds in the scene. In this paper, we present an adaptive anomaly detector...

PURPOSE To understand how the technology of electronic prescription (e Rx) can transform the community pharmacist's role through its effects on professionalization. We define professionalization as a pharmaceutical practice centred on clinical activities and made possible by the establishment of professional pharmaceutical services. METHODS We asked 12 community pharmacists who had participat...

We report the discovery of a narrow-line QSO (NLQSO) RX J1334.2+3759 with a steep soft X-ray spectrum. Soft X-ray emission from the NLQSO is highly variable. Changes in the intensity by a factor of ∼ 2 have been detected in the ROSAT PSPC observations of RX J1334.2+3759 on time scales of∼ 20000−40000 s. Rapid variability events have also been observed from RX J1334.2+3759. The most extreme vari...

At CITI, we run dataless AFS clients over dialup IP networks. Improving Rx performance is critical to that task. In this paper, we report on our progress in adapting Rx to networks characterized by low bandwidth, high delay, or variable round-trip time. Our focus is on adding facilities for congestion avoidance and control, and on compressing Rx headers. Although our work is ongoing, we have ov...

The Cannizzaro reaction ("RX C") and the benzoin reaction ("RX B") were investigated by density functional theory calculations. Reaction models (benzaldehyde)2 + X(-) + (H2O)n [for X(-) = OH(-) (RX C) n = 8, and for X(-) = CN(-) (RX B) n = 8 or n = 14] were adopted. Three transition states (TSs) were obtained for RX C, and the rate-determining step was confirmed to be the hydride shift. The sin...

This study was carried out to determine the effects of cadmium (Cd) (0 and 2 mg kg-1 soil) and salt stress (NaCl 0 and 3000 mg kg-1 soil) on shoot dry weights and shoot Cd, sodium (Na) and potassium (K) concentrations of salt-tolerant (Maverik) and salt-sensitive (RX-9292) hybrid maize varieties. Plants were grown under controlled greenhouse conditions for 19 days. Shoot dry matter productions ...

We have isolated chick rax/rx cDNAs, cRaxL (chick Rax/Rx-like) and cRax, (chick Rax) and examined their expression patterns during early eye and brain development. The cRaxL cDNA encodes a 228 amino acid protein that is most closely related to the zebrafish Rx1 and Rx2. The cRax cDNA encodes a 317 amino acid protein, which shares higher homology with the Xenopus Rx. In addition to the homeodoma...
