infection of specific-pathogen-free pigs by a genotype 4 strain of human hepatitis E virus. To the Editor: Peste des petits ruminants (PPR) is a viral disease of sheep and goats caused by peste des petits ruminants virus (PPRV), a negative-sense, single-stranded RNA virus of the genus Morbilli-virus. Illness and death can be high (>90%) when PPR occurs in populations of immunologically naive sh...

~ We study. adaptive finite element methods for elliptic problems with domain corner singularities. Our model problem is the two dimensional Poisson equation. Results of this paper are two folds. First, we prove that there exists an adaptive mesh (gauged by a discrete mesh density function) under which the recovered.gradient by the Polynomial Preserving Recovery (PPR) is superconvergent. Second...

In der Versicherungswirtschaft ermöglichen ubiquitäre Informationssysteme neuartige Prämienmodelle nach dem "Pay-Per-Risk" (PPR) Prinzip. In PPR Tarifen sind Prämien nicht vertraglich fixiert, sondern in gewissen Grenzen variabel und werden basierend auf objektiven Sensorinformationen in regelmäßigen Intervallen neu bestimmt. Für zwei Fallbeispiele aus dem Sachversicherungsbereich werden Anford...

Sixty-five outpatients with photoparoxysmal response (PPR) during routine EEG were studied. The PPR showed prevalence in women (75.4%). Seizures were found in 66.1% of cases. The rest recordings were abnormal in 41.8% with prevalence of generalized paroxysm. Eight patterns of PPR were observed, being polyspike mixed to slow wave the most frequent (53%). The epileptic group showed a bimodal dist...

This paper examines the implementation of projection pursuit regression (PPR) in the context of machine learning and neural networks. We propose a parametric PPR with direct training which achieves improved training speed and accuracy when compared with nonparametric PPR. Analysis and simulations are done for heuristics to choose good initial projection directions. A comparison of a projection ...

Epidemiological and virological investigations were carried out during an outbreak of Peste des petits ruminants (PPR) in Afghan (Bulkhi) sheep in Pakistan. The overall morbidity, mortality and case fatality rates were 41.0, 1.2 and 3.0%, respectively. The epidemic curve was plotted and the values for basic reproductive number (R0) and herd immunity threshold (HIT) for the affected flock were e...

The potentially preventable readmission (PPR) method uses administrative data to identify hospital readmissions that may indicate problems with quality of care. The PPR logic determines whether the reason for readmission is clinically related to a prior admission, and therefore potentially preventable. The likelihood of a PPR was found to be dependent on severity of illness, extremes of age, an...

The integrity of elliptic curve cryptography (ECC) stems from the presumed complexity of the elliptic curve discrete logarithm problem (ECDLP). Thus, the study of algorithms to solve the ECDLP is essential for two reasons: (1) to establish the integrity of ECC, and (2) to guide designers in the choice of ECC parameters, such as the length of the parameters and the characteristics of the curve. ...

Photoactive yellow protein (E-PYP) is a blue light photoreceptor, implicated in a negative phototactic response in Ectothiorhodospira halophila, that also serves as a model for the Per-Arnt-Sim superfamily of signaling molecules. Because no biological signaling partner for E-PYP has been identified, it has not been possible to correlate any of its photocycle intermediates with a relevant signal...

We study a problem of quick detection of top-k Personalized PageRank (PPR) lists. This problem has a number of important applications such as finding local cuts in large graphs, estimation of similarity distance and person name disambiguation. We argue that two observations are important when finding top-k PPR lists. Firstly, it is crucial that we detect fast the top-k most important neighbors ...
