I compare the (prototype) calculations of special F 4 and R terms in the effective actions of the Spin(32)/Z2 heterotic and type I string theories, compactified on S and T . Besides checking duality, this elucidates the quantitative rules of D-brane calculus. I explain in particular (a) why D-branes do not run in loops, and (b) how their instanton contributions arise from orbifold fixed points ...

In this paper, we concentrate our attention on the Müntz problem in the univariate setting and for the uniform norm. MSC: 41-01, 41-02

We argue that there are two distinct classes of type I compactification to four dimensions on any space. These two classes are distinguished in a mysterious way by the presence (or absence) of a discrete 6-form potential. In simple examples, duality suggests that the new class of compactifications have reduced numbers of moduli. We also point out analogous discrete choices in M, F and type II c...

Type I hypersensitivity reactions occur in individuals who have been previously sensitized to a specific allergen. They are the result of allergen recognition by immunoglobulin E on mast cells and basophils and cause a variety of symptoms such as itching or tingling of the lips, tongue or throat; nausea, vomiting and diarrhoea; sneezing, runny nose and wheezing, shortness of breath and coughing...

Background  Recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (LLLT). The aim of this study was to determine whether LLLT could induce a bio-stimulatory effects on human gingival fibroblasts (HGF3-PI 53). Therefore, the effect of laser irradiation on human gingival cell proliferation and collagen type I gene ...

Sumac (Rhus coriaria L.) is used as an herbal remedy in traditional medicine. The aim of this study was to determine the effects of sumac (Rhus coriaria L.) on serum glycemic status, apolipoprotein (apo) B, apoA-I and total antioxidant capacity (TAC) in type 2 diabetic patients. This double blind randomized controlled clinical trial was conducted on 41 type 2 diabetic volunteers randomly assign...
