PURPOSE Unique features of adolescent cancer patients include cancer types, developmental stages, and psychosocial issues. In this study, we evaluated the relationship between diagnostic delay and survival to improve adolescent cancer care. MATERIALS AND METHODS A total of 592 patients aged 0-18 years with eight common cancers were grouped according to age (adolescents, ≥10 years; children, <...

A novel driver with discharge current compensation is proposed to drive an ac plasma display panel (PDP). This proposed circuit uses resonance between the inductor and the ac PDP to avoid abrupt charging/discharging. The four switches of the full bridge are all operated with zero-voltage-switching turn-on. In addition, an 8-in ac PDP equipped with the proposed driving circuit, operating at 100 ...

In pickup and delivery problems (PDPs), vehicles pickup and deliver a set of items under various constraints. We address the PDP with Transfers (PDP-T), in which vehicles plan to transfer items between one another to form more efficient schedules. We introduce the Very Large Neighborhood Search with Transfers (VLNS-T) algorithm to form schedules for the PDP-T. Our approach allows multiple trans...

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...

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...
