The integral membrane protein tetherin has been associated with an eclectic mix of cellular processes, including restricting the release of a range of enveloped viruses from infected cells. The unusual topology of tetherin (it possesses both a conventional transmembrane domain and a glycosylphosphatidylinositol anchor), its localisation to membrane microdomains (lipid rafts) and the fact that i...

This paper examines the problem of estimating surface shape from texture in situations in which there are multiple textures present due to texture discontinuities, occlusion, and pseudo-transparency (for example looking through a picket fence at a textured surface). Previous shape-from-texture methods that use changes in the spatial frequencyrepresentation of neighboring image patches assume th...

Aluminum(III) porphyrins are examined as potential fluoride selective ionophores in polymeric membrane type ionselective electrodes. Membranes formulated with Al(III) tetraphenyl (TPP) or octaethyl (OEP) porphyrins are shown to exhibit enhanced potentiometric selectivity for fluoride over more lipophilic anions, including perchlorate and thiocyanate. However, such membrane electrodes display un...

Previous research has established that individuals from a lower social class report lower relationship quality. However, to date, no studies have examined interdependence processes within the relationship as a mechanism underlying this association. The present research investigates the role of planned tangible investments as a mediator between social class and relationship quality. Across two s...

The detection of tonal signals with unknown frequencies is an important area study in underwater signal processing. A common approach to address this issue use the Discrete Fourier Transform (DFT) for observations. When a tone does not lie precisely at discrete DFT frequency point, its energy will leak adjacent point. This phenomenon known as scalloping loss or Picket Fence Effect (PFE). PFE le...

Recently, ground state eigenvectors of the reduced Bardeen–Cooper–Schrieffer (BCS) Hamiltonian, Richardson–Gaudin (RG) states, have been employed as a wavefunction ansatz for strong correlation. This physically represents mean-field pairs electrons (geminals) with constant pairing strength. To move beyond mean-field, one must develop on basis all RG states. requires both practical expressions t...

In this paper, we introduce a modified fence fill algorithm for filling a polygon. Fence fill algorithm is a modified edge fill algorithm. As opposed to the edge fill algorithm that fills pixels starting from the polygon edge to the maximum screen coordinates, the fence fill algorithm fills pixels bounded by the polygon edge and the fence. This involves large number of calculations to find the ...

An editable rounded leaf offset (RLO) table is provided in the Pinnacle3 treatment planning software. Default tables are provided for major linear accelerator manu- facturers, but it is not clear how the default table values should be adjusted by the user to optimize agreement between the calculated leaf tip value and the actual measured value. Since we wish for the calculated MLC-defined field...
