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...

Reversibility is a basic and crucial feature of supramolecular systems. In designing and fabricating new supramolecular materials, the realization of reversibility is particularly important as it could enable these substances to be superior to conventional materials. An excellent example is an elastomer reported recently, made of small functional molecules which form both long chains and cross-...

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. ...

Aim: To develop a simple mathematical model to assess the losses due to peste des petits ruminants (PPR) in small ruminants in India. Materials and Methods: The study was based on cases and deaths in goats and sheep due to PPR from the average combined data on ovine/caprine as published by Government of India for the last 5 years (2008-2012). All possible direct and indirect losses due to the d...

TAKE-HOME SUMMARY Personalized pulmonary rehabilitation including occupational therapy improves the prognosis of patients with advanced COPD. PURPOSE We previously reported that patients with chronic obstructive pulmonary disease (COPD) exhibit three exercise-induced life-threatening conditions: hypoxemia, sympathetic overactivity, and respiratory acidosis. We aimed to verify whether mortalit...

Pentatricopeptide repeat (PPR) proteins form the largest known RNA-binding protein family and are found in all eukaryotes, being particularly abundant in higher plants. PPR proteins localize mostly in mitochondria and chloroplasts, where they modulate organellar genome expression on the post-transcriptional level. The Saccharomyces cerevisiae DMR1 (CCM1, YGR150C) encodes a PPR protein that loca...
