primary amyloidosis is a rare disrder wihich is diagnosed by extracellular deposition of proteinaceous material in different organs.in this report,a case of this disease with prominent hepatic involvement is presented.the case is a 63 years old male refered with abdominal enlargement,weight loss,generalized pruritus,anorexia and vague abdominal pain started from six months ago.on physical exami...

the main objective of this study is to swing krull intersection theorem in primary decomposition of rings and modules to the primary decomposition of soft rings and soft modules. to fulfill this aim several notions like soft prime ideals, soft maximal ideals, soft primary ideals, and soft radical ideals are introduced for a soft ring over a given unitary commutative ring. consequently, the p...

The background of Stevenson’s story is viewed as a stylized model of participation in a financial pyramid. You are invited to take part in a dubious activity. If you refuse, you neither gain nor lose anything. If you accept, you will gain if you are able to find somebody who will take your place on exactly the same conditions, but suffer a loss otherwise. The catch is that there is a finite num...

Variational sparsity regularization based on l1-norms and other nonlinear functionals has gained enormous attention recently, both with respect to its applications and its mathematical analysis. A focus in regularization theory has been to develop error estimation in terms of regularization parameter and noise strength. For this sake specific error measures such as Bregman distances and specifi...

We present a new general asymptotic theory for the maximum of a random array {Xn(i) : 1 ≤ i ≤ L}n≥1, where each Xn(i) is assumed to converge in probability as n → ∞. The array dimension L is allowed to increase with the sample size n. Existing extreme value theory arguments focus on observed data Xn(i), and require a well defined limit law for max1≤i≤L |Xn(i)| by restricting dependence across i...

We consider Kirchhoff equations with strong damping, namely with a friction term which depends on a power of the “elastic” operator. We address local and global existence of solutions in two different regimes depending on the exponent in the friction term. When the exponent is greater than 1/2, the dissipation prevails, and we obtain global existence in the energy space assuming only degenerate...

The coalescent revolutionised theoretical population genetics, simplifying, or making possible for the first time, many analyses, proofs, and derivations, and offering crucial insights about the way in which the structure of data in samples from populations depends on the demographic history of the population. However statistical inference under the coalescent model is extremely challenging, ef...

We consider the roots of uniformly chosen complex and real reciprocal polynomials of degree N whose Mahler measure is bounded by a constant. After a change of variables this reduces to a generalization of Ginibre’s complex and real ensembles of random matrices where the weight functions (on the eigenvalues of the matrices) is replaced by the exponentiated equilibrium potential of the interval [...

extramedullary plasmacytoma (emp) is a rare neoplasm of soft tissue which usually arises in the respiratory tract, nasal cavity, sinuses and nasopharynx. multiple extramedullary plasmacytomas are extremely rare, especially those that are not associated with multiple myeloma.we describe multiple primary emp in a 37 year old man, without involvement of bone or bone marrow. emp usually has a good ...

epidemiological studies have shown wide geographical and racial variation in the prevalence and patterns of immunodeficiency disorders. to determine the frequency of primary immunodeficiencies (pid) in iran, the iranian primary immunodeficiencies registry (ipidr) was organized in 1999. the diagnosis of immunodeficiency in our patients was based on standard criteria. the patient’s data were extr...
