The Structural Status of Iranian Medical Journals Based on the Medline Selection Criteria
Introduction: In recent years, the number of academic medical research journals has increased in Iran. These journals must be based on the standards and criteria required in international indexing databases in order to be indexed.

Operator-valued pseudo-differential operators and the twisted index pairing [PDF]
The notion of pseudo-differential operators with coefficients in a continuous trace algebra over a manifold are introduced and their index theory is studied. The algebra of principal symbols in this calculus provides an abstract Poincar\'e dual to the continuous trace algebra.

An anticipating tangent to a semimartingale [PDF]
We construct a perturbation of identity type mapping on an abstract Wiener space where the Cameron-Martin space has an orthonormal basis indexed by the jumps a one dimensional semimartingale. We then derive a change of variables formula and a degree type result for this map.

Exchangeable Laws in Borel Data Structures [PDF]
Motivated by statistical practice, category theory terminology is used to introduce Borel data structures and study exchangeability in an abstract framework. A generalization of de Finetti's theorem is shown and natural transformations are used to present functional representation theorems (FRTs). Proofs of the latter are based on a classical result by

Dirichlet-to-Neumann Maps, Abstract Weyl-Titchmarsh $M$-Functions, and a Generalized Index of Unbounded Meromorphic Operator-Valued Functions [PDF]
We introduce a generalized index for certain meromorphic, unbounded, operator-valued functions. The class of functions is chosen such that energy parameter dependent Dirichlet-to-Neumann maps associated to uniformly elliptic partial differential operators, particularly, non-self-adjoint Schr\"odinger operators, on bounded Lipschitz domains, and ...

Atiyah-Patodi-Singer index theorem for domain-wall fermion Dirac operator [PDF]
Recently, the Atiyah-Patodi-Singer(APS) index theorem attracts attention for understanding physics on the surface of materials in topological phases. Although it is widely applied to physics, the mathematical set-up in the original APS index theorem is too abstract and general (allowing non-trivial metric and so on) and also the connection between the ...

How to Get Iranian Journals Better Indexed by Foreign Databases?
Since increasing the number of indexing and abstracting services covering a journal would increase the total citations received by the journal, this study tried to investigate the reasons why Iranian journals are not indexed by foreign databases ...

Progressive Neural Index Search for Database System [PDF]
As a key ingredient of the DBMS, index plays an important role in the query optimization and processing. However, it is a non-trivial task to apply existing indexes or design new indexes for new applications, where both data distribution and query distribution are unknown.
