microscopy. Quantitative analysis of the movies revealed a clear posterior-to-anterior gradient of cell motility and directionality in the PSM. We tracked the movement of the PSM extracellular matrix (ECM) in parallel to the labelled cells and substracted the ECM movement to the global motion of cells. After substraction, cell movements remained consistently graded but lacked directionality. Th...

OBJECTIVE AND BACKGROUND Moyamoya disease is an idiopathic vasculopathy of circle of Willis. Stroke is a common presentation. We describe clinical and radiological features of moyamoya disease in four patients. SETTING Tertiary care center in a metropolitan city. MATERIALS AND METHODS Patients with moyamoya disease were identified by ICD-9 coding system of the hospital medical records. Demo...

Our researches have been made on brown forest soil that had been used in long-term experiments set up according to specified fertilization system for over 30 years. We have chosen those experiment variants in which quantities of nitrogen fertilizers were gradually increased. The soil samples taken from 0 cm to 30 cm depth were used to determine biological indexes of nitrogen availability (aerob...

We prove that the thermodynamic properties of a Schwarzschild black hole are unaffected by an external magnetic field passing through it. Apart from the background substraction prescription, this result is obtained also by using a counterterm method. The black holes created in astrophysical processes are expected to be well described by asymptotically flat solutions of Einstein equations. Howev...

We compared three different channel normalisation (CN) methods in the context of a connected digit recognition task over the phone: ceptrum mean substraction (CMS), RASTA filtering and the Gaussian dynamic cepstrum reprsentation (GDCR). Using a small set of context-independent (CI) continuous Gaussian mixture hidden Markov models (HMMs) we found that CMS and RASTA outperformed the GDCR techniqu...

Let b, c be positive integers, x1, x2 be indeterminates over Z and xm,m ∈ Z be rational functions defined by xm−1xm+1 = x b m+1 if m is odd and xm−1xm+1 = x c m+1 if m is even. In this short note, we prove that for any m,k ∈ Z, xk can be expressed as a substraction-free Laurent polynomial in Z[x±1 m , x ±1 m+1]. This proves FominZelevinsky’s positivity conjecture for coefficient-free rank two c...

the treatise entitled “arithmetic in astronomy”, which is edited and commented upon in this paper, is part of an old manuscript collection preserved in the national library of bosnia and herzegovina. at the end of this treatise there are some phrases in arabic which show that the treatise was originally part of a persian book written by ʿalī al-qūshchī. this manuscript is, in fact, an abridged ...

Polarization of a vacuum as well dispersive and dissipative dielectric media with piece-wise smooth inhomogeneities is studied the goal to clarify question renormalizability diverging electromagnetic stress-energy tensor. First, stress tensor computed Lifshitz approach London forces in non-retarded limit, which after substraction leading free space ultraviolet divergencies still retains associa...
