Background. Currently, scleroderma is a rather rare disease, including among children. Despite the growing interest of investigators in this pathology, the problem of diagnosing oesophageal affection in various forms of systemic sclerosis remains under ...

Systemic sclerosis (Scleroderma) and malignancy
The association of malignancy with collagen diseases has been a focus of interest. Especially, relation between dermatomyositis and malignancy is well-recognized. I reviewed here about the coexistence of SSc and malignancy in literature. I would like to raise four points as characteristics of the relationship.

Linearly repetitive Delone systems have a finite number of non periodic Delone system factors [PDF]
We prove linearly repetitive Delone systems have finitely many Delone system factors up to conjugacy. This result is also applicable to linearly repetitive tiling systems.

Integral equivalence of multidimensional differential systems [PDF]
The bases of the theory of integrals for multidimensional differential systems are stated. The integral equivalence of total differential systems, linear homogeneous systems of partial differential equations, and Pfaff systems of equations is established.

Fractional Multidimensional System [PDF]
The multidimensional ($n$-D) systems described by Roesser model are presented in this paper. These $n$-D systems consist of discrete systems and continuous fractional order systems with fractional order $\nu$, $0<\nu<1$. The stability and Robust stability of such $n$-D systems are investigated.

Background: Systemic sclerosis is a multi-systemic autoimmune disorder characterised by the generation of autoantibodies, massive deposition of collagen and other matrix substances in the connective tissues and alterations of the microvasculature ...

The paper deals with combinatorial and stochastic structures of cubical token systems. A cubical token system is an instance of a token system, which in turn is an instance of a transition system. It is shown that some basic results of combinatorial and stochastic parts of media theory hold almost in identical form for cubical token systems, although ...

Separable bi-Hamiltonian systems with quadratic in momenta first integrals [PDF]
Geometric separability theory of Gel'fand-Zakharevich bi-Hamiltonian systems on Riemannian manifolds is reviewed and developed. Particular attention is paid to the separability of systems generated by the so-called special conformal Killing tensors, i.e. Benenti systems.
