This work developed a three-dimensional (3D) diffusion-prepared segmented steady-steady free precession (DP-SSFP) cardiovascular magnetic resonance (CMR) sequence for black-blood (BB) thoracic aortic and carotid wall visualization. In 14 healthy volunteers, BB CMR of the thoracic aorta (n = 7) and carotid arteries (n = 7) was performed over 12 cm and 3 cm of transversal coverage, respectively, ...

We show that the system of difference equations zn+1 = wa n zb n−1 , wn+1 = zc n wd n−1 , n ∈ N0, where a, b, c, d ∈ Z, and initial values z−1, z0, w−1, w0 ∈ C, is solvable in closed form, and present a method for finding its solutions.

As to traditional n-gram model, smaller n value is an inherent defect for estimating language probabilities in speech recognition, simply because that estimation could not be executed over farther word association but by means of short sequential word correlated information. This has an strong effect on the performance of speech recognition. This paper introduces an integrated language modeling...

Hospital-based supervised exercise (SEP) is a guideline-recommended intervention for patients with intermittent claudication (IC). However, due to the limited availability of SEP, home-based structured programs (HSEP) have become increasingly popular alongside “go home and walk” advice. We evaluated cost-effectiveness walk advice (WA) Nordic pole walking vs. SEP combined WA or HSEP WA. used dat...

The main result of the paper is to get the transition formulae between the alcove form and the permutation form of w ∈ Wa, where Wa is an affine Weyl group of classical type. On the other hand, we get a new characterization for the alcove form of an affine Weyl group element which has a much simpler form compared with that in [10]. As applications, we give an affirmative answer to a conjecture ...

since the beginning of the presence of the holy qur’an, criticism and rhetoric have received attention in the areas of culture and thought, too. in this respect we can name some literary and rhetorical works like maj?z al-qur’?n by abu ubaydah ma’mar ibn muthann?, ket?b al-fas?hah by abu h?tam sajest?ni, e’j?z al-qur’?n by j?hez basri, naqd al-nathr wa naqd al-she’r by abu al-faraj qud?mah ibn ...

The effect of short and repetitive exposure to cold (5 degrees C, 4 hr/day for 2 weeks) from the birth up to the 14th day of newborn rats onthe thermal regulation in adulthood and on the tolerance to cold was investigated. After being exposed to cold, they were transferred to a room at 25 degrees C (N-CA). The control rats were raised at 25 degrees C (N-WA). An acute cold exposure test was perf...
