This note is a slightly revised version of an earlier note with the same title that was part of a larger research project of the Dynamical Systems Group at Ohio University. While the major findings of the project are described in [1], this note complements [1] as it contains a more extensive review of some basic low-dimensional examples of Boolean systems and their ODE counterparts and explores...
Human blood coagulation Factor XI was purified in 20% yield from plasma by ion exchange chromatography. The specific clotting activity of purified Factor XI was 250 & 20 units/mg implying that its concentration in normal titrated human plasma is 4 pg/ml. The purified Factor XI in its precursor form gave a single protein band on polyacrylamide gels in the presence of sodium dodecyl sulfate with ...
Throughout this paper, we use intA and CoA to denote the interior and the convex hull of a set A, respectively. Let I be an index set. For each i ∈ I , let Yi, Ei be two Hausdorff topological vector spaces. Consider a family of nonempty convex subsets {Xi}i∈I with Xi ⊆ Ei. Let X = ∏ i∈I Xi and E = ∏ i∈I Ei. An element of the set Xi = ∏ j∈I\i Xi will be denoted by xi; therefore, x ∈ X will be wr...
In this paper, we prove the stability of the functional equation ∑ 1 i, j n,i = j ( f (xi + x j)+ f (xi − x j) ) = (n−1) n ∑ i=1 ( 3 f (xi)+ f (−xi) ) in non-Archimedean normed spaces. Mathematics subject classification (2010): 39B82, 46S10, 39B52.
1 Proofs of propositions Proof. (of Proposition 4.1) Let Xi = X InfMax i for short. First, observe that X1 ∈ P1. This is because the greedy algorithm maximizes marginal gain, and no point on P1 can dominate this, no matter what the costs are. Next, suppose we have Xi−1 ∈ Pi−1. Since Xi is obtained from Xi−1 by adding that u that maximizes marginal gain in I(·), no point on Pi can dominate Xi. T...
Consider a stochastic difference equation xi+1 = Gi [xi, xi−1, . . . , x0] + fi [xi, xi−1, . . . , x0] + k0 ∑ k=0 σi−k [xi−k, xi−k−1, . . . , x0] ξi+1−k, (1) with the Volterra type nonlinear main term G and the Volterra type noise f + ∑k0 k=0 σi−kξi+1−k. Functions Gi, fi, σi are random while ξi is a martingale-difference. In general, k0 ≥ 1 so Eqn (1) cannot be considered as a stochastic equati...
OBJECTIVE Coagulation factor XI is proposed as therapeutic target for anticoagulation. However, it is still unclear whether the antithrombotic properties of factor XI inhibitors influence atherosclerotic disease and atherothrombosis. Our aim is to investigate whether factor XI antisense oligonucleotides could prevent thrombus formation on acutely ruptured atherosclerotic plaques. APPROACH AND...

We associate to certain symmetric or antisymmetric functions on the set ( E d+1 ) of (d+ 1)−subsets in a finite set E an equivalence relation on E and study some of its properties. 1 Definitions and main results We consider a finite set E and denote by (E d ) the set of subsets containing exactly d elements of E. In the sequel we move often freely from sets to sequences: we identify a subset {x...
