We present spectroscopy of seven cataclysmic variable stars with orbital periods Porb greater than 5 hours, all but one of which are known to be dwarf novae. Using radial velocity measurements we improve on previous orbital period determinations, or derive periods for the first time. The stars and their periods are TT Crt, 0.2683522(5) d; EZ Del, 0.2234(5) d; LL Lyr, 0.249069(4) d; UY Pup, 0.47...

Sequences encoding RNase P RNAs from representatives of the last remaining classical phyla of Bacteria have been determined, completing a general phylogenetic survey of RNase P RNA sequence and structure. This broad sampling of RNase P RNAs allows some refinement of the secondary structure, and reveals patterns in the evolutionary variation of sequences and secondary structures. Although the se...

In this paper, we propose the introduction of a frequency domain variable perturbation control and a leaky algorithm to the frequency domain time difference simultaneous perturbation (FDTDSP) method in order to improve the cancellation performance and the stability of the active noise control (ANC) system using the perturbation method. Since the ANC system using the perturbation method does not...

Tn7::In2-8 contains sat2-aadB-catB2(deltaattC)-dfrA1-sat2-aadA1-orfX in the variable region of a class 2 integron embedded in the Tn7-like transposon. This novel transposon was inserted in its preferred site downstream of the glms gene in Acinetobacter baumannii. Acquisition of the pseudocassette catB2 could have arisen by a secondary-site integrase-mediated intermolecular recombination event.

In this paper, we study a class of stochastic optimal control problems, where the drift term of the equation has a linear growth on the control variable, the cost functional has a quadratic growth, and the control process belongs to the class of square integrable, adapted processes with no bound assumed on it. 2000 Mathematics Subject Classification: Primary 45D05 Secondary 93E20, 60H30

OBJECTIVE To test discriminant analysis as a method of turning the information of a routine customer satisfaction survey (CSS) into a more accurate decision-making tool. METHODS A 7-question, 10-multiple choice, self-applied questionnaire was used to study a sample of patients seen in two outpatient care units in Valparaíso, Chile, one of primary care (n=100) and the other of secondary care (...

Static Single Assignment (SSA) intermediate representations have become quite popular in compiler development. One advantage of the SSA form is that each use of a variable corresponds to exactly one de nition, and thus two references of the same SSA variable must denote the same value. To date, most SSA forms concentrate on scalar variables, and it is di cult to extend these intermediate repres...

The chlamydiae are obligate intracellular bacteria that occupy a non-acidified vacuole (the inclusion) during their entire developmental cycle. These bacteria produce a set of proteins (Inc proteins) that localize to the surface of the inclusion within infected cells. Chlamydia trachomatis IncA is also commonly found in long fibers that extend away from the inclusion. We used standard and confo...
