Introduction: Quantitative analysis of first-pass contrast-enhanced cardiac perfusion MRI requires a conversion of the T1-weighted signal-time curve to contrast agent (Gd-DTPA) concentration-time curve. For this purpose, a theory-based single-point T1 measurement method has been proposed and validated in phantoms at 1.5T [1-2]. The specific choice of the k-space ordering of the TurboFLASH reado...

Karen A. , P. Kovács, J .F. Beckers , O. Szenci : Pregnancy Diagnosis in Sheep: Review of the Most Practical Methods. Acta Vet. Brno 2001, 70: 115-126. Various practical methods have been used for pregnancy diagnosis in sheep. Both pregnancy and fetal numbers are accurately diagnosed by using radiography after day 70 of gestation. Rectal abdominal technique detects pregnancy with an accuracy of...

We propose a new scheme on unidirectional surface plasmonpolariton (SPP) excitation with the following advantages: ultracompact size, working at arbitrary incidence angle and over a wide spectrum. The proposed structure utilizes a partially filled metallic slot with dielectric to realize unidirectional SPP excitation via direct field manipulation. We theoretically and numerically show that unid...

Well-characterized solid-state laser materials are evaluated for performance in optical refrigeration as well as radiation-balanced laser systems. New figures-of-merit are developed and applied to ytterbium-doped materials. Superior performance is predicted for high-cross-section tungstate materials. Photothermal deflection experiments on samples of Yb3+-doped KGd(WO4)2 confirm anti-Stokes fluo...

Patients with a rare bleeding disorder characterised by skin and mucosal bleeding – typical of thrombocytopenia – but with a normal platelet count, and later characterised by a defective aggregation to all agonists, described as Glanzmann thrombasthenia, have mutations in a platelet membrane glycoprotein (GP) called GP IIb/IIIa, also known as the integrin αIIbβ3 (1). Such discovery paved the ro...

The design, fabrication and spectroscopic characterization of ytterbium-doped Ta2O5 rib waveguide are described. The waveguides are fabricated on silicon substrates and operate in a single mode at wavelengths above 970 nm. The peak absorption cross-section was measured to be 2.75 × 10 cm at 975 nm. The emission spectrum was found to have a broad fluorescence spanning from 990 nm to 1090 nm with...

We demonstrate a source of 554 nm pulses with 2.7 ps pulse duration and 1.41 W average power, at a repetition rate of 300 MHz. The yellow-green pulse train is generated from the second harmonic of a 1.11 μm fiber laser source in periodically-poled stoichiometric LiTaO3. A total fundamental power of 2.52 W was used, giving a conversion efficiency of 56%. © 2014 Optical Society of America OCIS co...

A day hospital program for the treatment of patients with long-term anorexia nervosa (AN) is described. This program forms part of a comprehensive system of day programs that reflect and incorporate patients’ varying degrees of readiness for change and attempt to match patients’ readiness for change to the interventions offered in treatment. Preliminary outcome data are presented, showing clini...
