Complexities in the X-ray spectrum of the nearby Seyfert 1.2 galaxy MCG–6-30-15 are commonly interpreted in terms of a broad iron line and the associated Compton reflection hump from the innermost relativistic regions of an accretion disk around a rapidly spinning black hole. However, an alternative model has recently been proposed in which these spectral features are caused entirely by complex...

A gamma-ray burst of 28 August 1997 was localized by the All-Sky Monitor on the Rossi XTE satellite and its coordinates were promptly disseminated. An ASCA followup started 1.17 days after the burst as a Target of Opportunity Observation and detected an X-ray afterglow. The spectral data displayed a hump around ∼ 5 keV and an absorption column of 7.1×10 cm. This hump structure is likely a recom...

The patient was a 71-year-old female with Torsade de Pointes (TdP) associated with idiopathic long QT syndrome. TdP and polymorphic nonsustained VT were frequently observed at bedside and an electrophysiologic study was performed. The QT (and QTU) interval was abnormally prolonged, and alteration of the QT interval was also recorded on the electrocardiogram. Monophasic action potential (MAP) fr...

Lateral cordless fragments isolated from the postpharyngeal section of Dugesia dorotocephala formed a large normal head at a 90" angle to the original antero-posterior polarity; postcerebrally, only a hump of undifferentiated tissue developed. This "head-hump'' pattern, and also other types observed in previous studies of lateral fragments, were attributed to the absence of the nerve cord. In o...

Phorid flies are an abundant and diverse dipteran family in modern faunas, yet poorly represented the fossil record. Here, we describe first species of millipede parasitizing genus Myriophora, M. asiatica n. sp., three new ant Apocephalus, A. miocenus dominicanus chiapanecus sp. discovered Miocene amber deposits from China, Dominican Republic, Mexico, respectively. Moreover, add details on Apoc...
