Background CMR tagging in polar patterns is desirable because of its close compatibility to the annular geometry and motion of the left ventricle in short axis view. This circular symmetry does not exist in some pathological cases neither in the normal long axis view. An oval-shaped pattern is more suitable for assessment of the deformation in these conditions. Herein, we present the non-unifor...

We present measured and calculated differential cross sections, as well as calculated integral cross sections, for elastic electron collisions with CH3F, CH2F2 , CHF3, and CF4. The calculated cross sections were obtained with the Schwinger multichannel method, and a Born-closure procedure was used to improve the differential cross sections for polar systems. Polarization effects were found to b...

Cells of the cellular slime mould D. discoideum were allowed to form into spherical aggregates, by shaking vegetative cells as a suspension in phosphate buffer. In such conditions, grex polarity is never established and surface sheath is not formed (Loomis, 1975 a). Despite the absence of such characteristics of normal development, differentiation of prespore cells, as tested for by immunofluor...

In this paper, a coherence function technique is introduced for Tangible Acoustic Interfaces (TAI) using the Location Template Matching (LTM) approach. A simple workflow is proposed for the purpose of evaluating the performance of different TAI techniques and investigating the effect of various parameters based on experimental data. Performance analysis shows that the method of magnitude square...

Spatio-temporal phenomena used to be represented in Cartesian Coordinate Systems, and time is perceived linear. This way of representing time may not be appropriate for representing and analysing some types of natural and human phenomena, which occur in time cycles. This paper thus proposes the use of polar coordinate systems. Polar angles are used to represent time, which can be clock time at ...

There are several performance parameters for gliders that are useful to know. The ones I focused on are generating a sink polar, finding minimum sink speed, finding maximum L/D speed, and creating a speed to fly curve. Modelers using a system such as the Eagletree Glide can optimize their cross country soaring techniques by flying at the appropriate airspeed for the current flight conditions. A...

High latitude ionospheric convection patterns and models are obtained based on a composite analysis of incoherent scatter radar (ISR) observations in the North America sector at Millstone Hill and Sondrestrom (MHS). These observations span a combined latitude range of 55 pLp82 over time periods starting from 1978 for Millstone Hill and from 1995 for Sondrestrom. These models, regional to the Am...
