We study principles of the form: if a name σ is forced to have certain property φ, then there ground model filter g such that σg satisfies φ. prove general correspondence connecting these forcing axioms. Special cases main theorem are: Any axiom can be expressed as principle. For instance, PFA equivalent to: A principle for rank 1 names (equivalently, nice names) subsets ω1. 2 sets reals. λ-bou...

Generalizing a previous one-variable " interlace polynomial " , we consider a new interlace polynomial in two variables. The polynomial can be computed in two very different ways. The first is an expansion analogous to the state space expansion of the Tutte polynomial; the differences are that our expansion is over vertex rather than edge subsets, the rank of the subset appears positively rathe...

Staphylococcus aureus (S. aureus) is a dangerous pathogen and a leading cause of both nosocomial and community acquired bacterial infection worldwide. However, on the other hand, we are all exposed to this bacterium, often within the first hours of life, and usually manage to establish equilibrium and coexist with it. What does the adaptive immune system contribute toward lifelong control of S....

As a pedagogical illustration of the Fourier-space approach to the crystallography of quasiperiodic crystals, a simple derivation is given of the spacegroup classification scheme for hexagonal and trigonal quasiperiodic crystals of rank 4. The categories, which can be directly inferred from the Fourier-space forms of the hexagonal and trigonal space groups for periodic crystals, describe genera...

A code C is Z2Z4-additive if the set of coordinates can be partitioned into two subsets X and Y such that the punctured code of C by deleting the coordinates outside X (respectively, Y ) is a binary linear code (respectively, a quaternary linear code). In this paper, the rank and dimension of the kernel for Z2Z4-linear codes, which are the corresponding binary codes of Z2Z4-additive codes, are ...

Given a bipartite graph G(V,E), V = A ∪̇B where |V | = n, |E| = m and a partition of the edge set into r ≤ m disjoint subsets E = E1 ∪̇E2 ∪̇ . . . ∪̇Er, which are called ranks, the rank-maximal matching problem is to find a matching M of G such that |M ∩ E1| is maximized and given that |M ∩ E1| is maximized, |M ∩ E2| is also maximized, and so on. Such a problem arises as an optimization criteria ov...

Human brucellosis is a major health problem in developing countries. A number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. Since the pathophysiology of this change is not well understood, we studied the T-cell subsets during the acute, subacute and chronic forms of human brucellosis. In this study we found alterations...

Partial remission in patients newly diagnosed with type 1 diabetes is a period of good glucose control that can last from several weeks to over a year. The clinical significance of the remission period is that patients might be more responsive to immunotherapy if treated within this period. This article provides clinical data that indicates the level of glucose control and insulin-secreting β-c...
