In order to state our theorems we need to view the Seiberg-Witten invariant of a smooth 4manifold as a multivariable (Laurent) polynomial. To do this, recall that the Seiberg-Witten invariant of a smooth closed oriented 4-manifold X with b2 (X) > 1 is an integer valued function which is defined on the set of spin c structures over X, (cf. [W], [KM],[Ko1],[T1]). In caseH1(X,Z) has no 2-torsion (...
متن کاملMolecular Basis of Electrocardiographic ST - Segment Elevation Ronald
ST elevation is a classical hallmark of acute transmural myocardial ischemia. Indeed, ST elevation is the major clinical criterion for committing patients with chest pain to emergent coronary revascularization. Despite its clinical importance, the mechanism of ST elevation remains unclear. Various studies have suggested that activation of sarcolemmal ATP-sensitive potassium (KATP) channels by i...
متن کاملThe Footprints of Dragons
Almost all our early ancestors believed the earth was inhabited, especially in unknown regions, by dragons. Where did they get such an idea? Did it stem from a universal human imagination? An inherited need or instinct? An inherited subconscious memory of dinosaurs? All these suggestions have been made, and taken seriously by groups of people. I believe dragons are the reflection, sometimes emb...

متن کاملThe pyrophysiology and sexuality of dragons.
To examine the means whereby dragons produce fire and steam, we have studied a related species, the desert-lizard Lacerta pyrophorus. Morphological studies showed that there were in the snout three distinctive features: (1) a dorsal swelling in the pharynx, the Organ of Feuerwerk, consisting of brown adipose tissue with an extensive sympathetic innervation; (2) greatly enlarged lachrymonasal du...
