We show that if a complete, doubling metric space is annulus linearly connected then its conformal dimension is greater than one, quantitatively. As a consequence, hyperbolic groups whose boundaries have no local cut points have conformal dimension greater than one; this answers a question of Bonk and Kleiner.
Many psychosocial factors have been identified as potential risk factors for ischaemic heart disease, and strong evidence has been put forward for several personality factors such as Type A behavioural pattern, hostility, depression, or social factors such as low socioeconomic status and lack of social support. (Table 1 ) Psychosocial stressors per se increase cardiac vulnerability by altering ...
The pursuit of the perfect biomarker in chronic obstructive pulmonary disease (COPD) has been fraught with peril. The dream, of course, is of a single, accessible and inexpensive laboratory test that can more accurately diagnose COPD, define its severity, or fluctuate in accordance with disease progression and remission. In its ideal form, it would allow for earlier diagnosis of disease or earl...
A 67-year-old male presented with left kidney stones in renal pelvis, 15 mm length. Preoperative CT showed massive splenomegaly. Retrograde intrarenal surgery approach was decided to avoid splenic injury, achieving the absence of residual stones.
Let S be the number of components in a finite discrete mixing distribution. We prove that the number of waves of panel being greater than or equal to 2S is a sufficient condition for global identification of a dynamic binary choice model in which all the parameters are heterogeneous. This model results in a mixture of S binary first-order Markov Chains.
We report modulation of the absorption coefficient at 1.3 μm in Ge/SiGe multiple quantum well heterostructures on silicon via the quantum-confined Stark effect. Strain engineering was exploited to increase the direct optical bandgap in the Ge quantum wells. We grew 9 nm-thick Ge quantum wells on a relaxed Si0.22Ge0.78 buffer and a contrast in the absorption coefficient of a factor of greater th...
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
The gene miR-17-92 encodes six different microRNAs, with one of these acting as an internal brake that opposes the oncogenic activity of the others in some cancer contexts.
