We establish results about the second cohomology with coefficients in trivial module, symmetric invariant bilinear forms and derivations of a Lie algebra extended over commutative associative without unit. These provide simple unified approach to number questions treated earlier completely separated ways: periodization semisimple algebras (Anna Larsson), derivation algebras, prescribed part, ni...

Exercise-induced bronchoconstriction (EIB) occurs in the majority of asthmatics following vigorous exercise. EIB is caused by a loss of water from the airways creating a hyperosmolar environment in the tissue that in turn triggers the release of bronchoconstrictive mediators. These bronchoconstrictive mediators, including histamine, cysteinyl leukotrienes (CysLTs) and prostaglandins, act at the...

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1290. 124 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9796-5.

We show that pointwise limits of semistatic trading strategies in discrete time are again strategies. The analysis is carried out full generality for a two-period model, and under probabilistic condition multiperiod, multistock models. Our result contrasts with counterexample Acciaio, Larsson, Schachermayer, shows their observation due to failure integrability rather than instability the form. ...

We present high speed real time, error free 4-PAM transmission for short range optical links based on a VCSEL operating at 850 nm, a multimode fibre and a simple intensity detector. Transmission speeds of 25 Gbps and 30 Gbps are demonstrated, and the maximum fibre reaches were 300 m and 200 m, respectively. The 4-PAM is also compared with OOK transmission at 25 Gbps, and we find that at this bi...
