hypercoagulable states are a group of conditions associated with an enhanced tendency toward blood clotting. although usual clinical manifestations of hypercoagulable states are thrombotic events such as deep venous thrombosis, hematoma can also occurs as a result of hypercoagulability in some patients. several inherited or acquired conditions may lead to hypercoagulable states. some of them in...

In this paper, binomial difference ideals are studied. Three canonical representations for Laurent binomial difference ideals are given in terms of the reduced Gröbner basis of Z[x]-lattices, regular and coherent difference ascending chains, and partial characters over Z[x]-lattices, respectively. Criteria for a Laurent binomial difference ideal to be reflexive, prime, well-mixed, and perfect a...

Emergence has a long and controversial history. In this paper we briefly review the primary strands of the debate, paying attention to its use in the fields of philosophy of science and mind, social science and systems theory including the theory of complex systems. We argue that it is important to recognize why emergence in social systems is fundamentally different from other natural systems. ...

We study the cohomology of reflexive rank 2 sheaves on smooth projective threefolds. Applications are given to the moduli space of reflexive sheaves.

objectives: it is important to recognize any risk factors for the development of injuries in the athletic population. the aim of this study was to investigate the association between joint hyper mobility and low back pain in iranian hyper mobile and non-hyper mobile athletes. methods: 50 athletic patients with low back pain (age=23.20±12.79 years) and 51 healthy athletes (age=24.28±13.70) from ...

Let $R$ be a commutative Noetherian ring. We prove that  over a local ring $R$ every finitely generated $R$-module $M$ of finite Gorenstein projective dimension has a Gorenstein projective cover$varphi:C rightarrow M$ such that $C$ is finitely generated and the projective dimension of $Kervarphi$ is finite and $varphi$ is surjective.
