In this paper, we describe the principles of operation of a plasma display panel (PDP) and the physical mechanisms controlling the performances of a PDP in terms of light emission efficiency, lifetime and image quality. Emphasis is put on the physics of the plasma occurring in a PDP cell, on the discharge optimization, and on the analysis of recent results provided by experimental and numerical...

Pachydermoperiostosis (PDP) is the primary form of hypertrophic osteoarthropathy. It is a very rare disease consisting of pachydermia, digital clubbing and radiologic periostosis. Various digestive symptoms in PDP are seen in 11-49% of patients and juvenile polyps may be found at gastric endoscopy. We report here the history of a patient with PDP who was referred for assessment of severe anemia...

We study the asymptotic behavior of multiscale stochastic gene networks using weak limits of Markov jump processes. Depending on the time and concentration scales of the system we distinguish four types of limits: continuous piecewise deterministic processes (PDP) with switching, PDP with jumps in the continuous variables, averaged PDP, and PDP with singular switching. We justify rigorously the...

Medical educators strive to promote the development of a sound professional identity in learners, yet it is challenging to design, implement, and sustain fair and meaningful assessments of professionalism to accomplish this goal. The authors developed and implemented a program built around a Web-based Professional Development Portfolio (PDP) to assess and document professional development in me...

With the widespread use of cloud computing and cloud storage, how to ensure the authenticity of data in remote storage is becoming a severe problem. Provable data possession (PDP) is a technique for a client to verify whether an untrusted server possesses the original data. Moreover, for the requirement of efficiency and instantaneity, clients need to verify the authenticity of stored data with...

Parallel Distributed Processing (PDP) models have been widely used for modeling cognitive tasks where accuracy or reaction time were the dependent performance measures. However, only few PDP models have attempted to model more brain-related data like event related potentials (ERPs). In this paper, we take a step towards using ERP data for model fitting by proposing a PDP model, which can succes...

Based on an exploratory case study regarding the types of institutions funding the research and development to obtain new tuberculosis vaccines, this article intends to provoke discussion regarding the provision of new vaccines targeting neglected disease. Although our findings and discussion are mainly relevant to the case presented here, some aspects are more generally applicable, especially ...

We consider the one-to-one Pickup and Delivery Problem (PDP) in Euclidean Space with arbitrary dimension d where n transportation requests are picked i.i.d. with a separate origin-destination pair for each object to be moved. First, we consider the problem from the customer perspective where the objective is to compute a plan for transporting the objects such that the Euclidean distance travele...

N europsychiatric symptoms, such as psychosis, are well described in Parkinson’s disease (PD); most appear to be due to disease pathology with exacerbation caused by dopaminergic treatment. More than 50% of patients with PD develop psychosis at some point throughout their disease course. Clinicians need to routinely assess patients with PD for psychotic symptoms, particularly hallucinations. Tr...

This paper presents a policy-based framework for managing access control in distributed heterogeneous systems. This framework is based on the PDP/PEP approach. The PDP (Policy Decision Point) is a network policy server responsible for supplying policy information for network devices and applications. The PEP (Policy Enforcement Point) is the policy client (usually, a component of the network de...
