Sign bit compression in fixed-point numbering systems can improve the dynamic range and round-off noise for signal processing algorithms. This paper analyses non-standard compression factors (CF) for compressed fixed-point data formats, where sign bit compression is performed on each individual fixed-point number. Although these compression techniques are applicable to other fixed-point formats...

BACKGROUND The aim of this study is to investigate the amount and the distribution of biofilm in patients wearing fixed appliances and its relation with age, gender, frequency of tooth brushing, and patient motivation. METHODS The sample comprised 52 patients (15.5 ± 3.6 years old, 30 females and 22 males) wearing fixed orthodontic appliances. Dental biofilm was assessed using a modified plaq...

BACKGROUND: Recently, the researches about herbal medicines as substitutes for chemical drugs have risen in number. OBJECTIVES: To add more aspects to this research area, this study evaluated the changes in biochemical factors of the blood serum due to the consumption of Thymus daenensis extract and the effect of the period of its consumption into the...

We perform the classical gravity calculations of the fixed scalar absorption cross-sections by D = 5 black holes with three charges and by D = 4 black holes with four charges. We obtain analytic results for the cases where the energy and the left and right moving temperatures are sufficiently low but have arbitrary ratios. In D = 5 the greybody factor is in perfect agreement with the recent cal...

We review a class of dynamical models in which top condensation occurs at the weak scale, giving rise to the large top quark mass and other phenomena. This typically requires a color embedding, SU (3) c → SU (3) 1 × SU (3) 2 , ergo " Topcolor. " Topcolor suggests a novel route to technicolor models in which sequential quarks condense under the Topcolor interaction to break electroweak symmetrie...

We analyze the phenomenology of the Higgs sector in a 5D model compactified on an S1/Z2 orbifold where the compactification scale MC is around the TeV scale. We show that the conventional MSSM Higgs boson mass bounds in 4D can be violated when we allow the gauge sector, Higgs and third family multiplets to live in the fifth extra dimension. Supersymmetry is broken at an orbifold fixed point whi...

Broadband communications lie at the heart of the developing information society. Employing a logistic diffusion model, we analyze the factors that influence the diffusion of fixed and mobile broadband. For fixed broadband diffusion, we find that local loop unbundling, income, population density, education, and price are significant factors of fixed broadband diffusion. For mobile broadband, mul...
