in this paper, we characterize multiresolution analysis(mra) parseval frame multiwavelets in l^2(r^d) with matrix dilations of the form (d f )(x) = sqrt{2}f (ax), where a is an arbitrary expanding dtimes d matrix with integer coefficients, such that |deta| =2. we study a class of generalized low pass matrix filters that allow us to define (and construct) the subclass of mra tight frame multiwav...

background: breast cancer is one of the most common cancers in the world, particularly in iran. there are many genomic and molecular factors that cause the occurrence of breast cancer. many markers are associated with tumor invasiveness. matrix metalloproteinase includes a family of zinc-dependent endopeptidases that degrade various components of the extracellular matrix and basement membrane. ...

fullerenes are closed−cage carbon molecules formed by 12 pentagonal and n/2 – 10hexagonal faces, where n is the number of carbon atoms. patrick fowler in his lecture inmcc 2009 asked about the wiener index of fullerenes in general. in this paper werespond partially to this question for an infinite class of fullerenes with exactly 10ncarbon atoms. our method is general and can be applied to full...

various morphologies of silica nanoparticles were synthesized by a microwave-assisted pechini method. silica nanostructures were synthesized via a fast reaction between tetra ethyl ortho silicate and ammonia at presence citric acid and other effective agents in pechini procedure. then for preparation of polymer-matrix nanocomposites, sio2 nanoparticles were added to poly carbonate (pc) and poly...

results based on the recent researches, certain mmps play critical role in breast cancer initiation, invasion, and metastasis. they can be regarded as predictive biomarkers of primary diagnosis and prognosis of breast cancer and have predictive value for evaluation of disease, tumor recurrence, invading of tumor cells to other sites and therapeutic outcomes. conclusions in summary, the results ...

results there were 39 cases with lymph node metastasis in 59 malignant tumors, and 0 cases in 6 benign follicular type tumors. the staining scores by jt-95 of the 39 tumors with lymph node metastasis were 5+ in eight cases and 6+ in 31 cases. on the other hand, the scores of 20 malignant tumors without lymph node metastasis were < 4+ in all of the cases. in the co-cultured assay, numerous adhes...

We study Gaussian valence bond states of continuous variable systems, obtained as the outputs of projection operations from an ancillary space of M infinitely entangled bonds connecting neighboring sites, applied at each of N sites of an harmonic chain. The entanglement distribution in Gaussian valence bond states can be controlled by varying the input amount of entanglement engineered in a (2M...

Solutions of the 3D nonlinear induction equation for dynamos in spiral galaxies are presented in this paper. Our model includes diierential rotation, ambipolar diiusion and, based on small-scale turbulence, eddy diiu-sivity and the tensorial {eeect underlying magnetic feedback. The nonaxisymmetric radial-azimuthal spiral pattern and the vertical stratiication of the galaxy are represented in th...

We connrm that a high circular velocity at the center is able to stabilize an entire stellar disk against bar-forming (m = 2) modes, irrespective of the dark halo density. Our simulations of unstable power-law disks also yield the growth rate and pattern speed of the dominant lop-sided (m = 1) mode in close agreement with that predicted by linear theory in our cleanest case. We show that these ...

Let G be a reductive Lie group, g its Lie algebra, and M a G-manifold. Suppose Ah(M) is a Uh(g)-equivariant quantization of the function algebra A(M) on M . We develop a method of restricting Ah(M) to the Uh(g)-equivariant quantization on Gorbits in M . We are concerned with those quantizations that may be simultaneously represented as subalgebras in U∗ h(g) and quotients of Ah(M). It turns out...
