The association of vascular nxvi of the face, predominantly unilateral in distribution, with homolateral changes in the cerebral cortex, has long been of interest to clinicians. The first case4 of this disorder was presented by W. Allen Sturge to the Clinical Society of London in 1879. Weber5 called attention to the characteristic roentgenological features of this disease in 1922, and in 1934. ...

Several models have been proposed in the field of psychophysics to quantify relationships between any stimulus (e.g., touch, sound, light, and smell) and the perceived response by individuals. One such model is referred to as the Weber-Fechner Law. The Weber −Fechner Law, however, is not one law, but two separate laws: Weber's Law and Fechner's Law. Moreover, not all human senses respond to sti...

The approximate number system (ANS) is assumingly related to mathematical learning but evidence supporting this assumption is mixed. The inconsistent findings might be attributed to the fact that different measures have been used to assess the ANS and mathematical skills. Moreover, associations between the performance on a measure of the ANS and mathematical skills may be discontinuous, i.e., s...

I dispute the worth of Professor Weber's analysis. Whilst his mathematical calculations in themselves I'm sure are flawless, there are a number of tacit assumptions made that undermine its meaningfulness, mainly about the psychology of choice of patterns. Weber first selects a set of "likely to be chosen" shapes, including lines, ticks and boxes. On what basis is it argued that users are likely...

Anterior and posterior uveitis has been described as an associated feature of the Weber Christian syndrome (Klien, I959), but only one report of a case has thus far appeared in the literature. The presence of uveitis in sections of an eye removed from a patient suffering from Weber Christian disease was described by Theobald (I953). Frayer, Wise, and Tsaltas (i968) described three cases of Webe...

In recent days, current research is going in alternative fuels due to increase in global warming and pollution in all over the world and also very stringent emission norms. In this way, the study on spray progress plays an important role in improving complete combustion and emission of fuel, because it is directly affects the air-fuel mixture formation. The macroscopic spray characteristics of ...

The Multisource Weber problem, also known as the continuous locationallocation problem, or as the Fermat-Weber problem, is considered here. A particular case of the Multisource Weber problem is the minimum sum-of-distances clustering problem, also known as the continuous p-median problem. The mathematical modelling of this problem leads to a min− sum−min formulation which, in addition to its in...

Sturge-Weber syndrome can be associated with facial port-wine stains and intracranial calcification, and concurrent Klippel-Trenaunay-Weber syndrome has been reported. Klippel-Trenaunay-Weber syndrome is a rare congenital mesodermal phakomatosis characterized by cutaneous hemangiomas, venous varicosities and soft tissue or bone hypertrophy of the affected extremities. This report is presented a...

We consider a variant of the Complex Multiplication (CM) method for constructing elliptic curves (ECs) of prime order with additional security properties. Our variant uses Weber polynomials whose discriminant D is congruent to 3 (mod 8), and is based on a new transformation for converting roots of Weber polynomials to their Hilbert counterparts. We also present a new theoretical estimate of the...

Phonon transport in argon and silicon thin films is examined using harmonic lattice dynamics theory and the Lennard-Jones and Stillinger-Weber potentials. Film thicknesses ranging from 0.8 to 33.5 nm for argon and 0.4 to 8.6 nm for silicon are examined at a temperature of 0 K. Both reconstructed films and films built using the bulk unit cell are considered. Phonon dispersion curves for the in-p...
