We report on an infant who underwent gross total resection (GTR) of a posterior fossa ependymoblastoma in the second month of life followed by chemotherapy with uneventful long-term survival for 12 years. Postoperative radiotherapy has been considered obligate to have a chance for prolonged survival, but is inadvisable in infants. To our knowledge, this is the first reported long-term survival ...

By using the most general form of Einstein equations for General Relativistic (GTR) spherical collapse of an isolated fluid having arbitrary equation of state and radiation transport properties, we show that they obey a Global Constraint, 2GM(r, t)/R(r, t)c2 ≤ 1, where R is the “invariant circumference radius”, t is the comoving time, and M(r, t) is the gravitational mass enclosed within a como...

Alexander Pope (1688±1744): his spinal deformity and his doctors. O.P. Sharma. #ERS Journals Ltd 1999. ABSTRACT: Alexander Pope was the towering figure of 18th century England. A poet and a wit he commanded unswerving loyalty from his friends and penetrating hatred from his enemies. His spinal deformity, either due to tuberculosis, trauma or congenital weakness, shaped his career. This brief re...

Research in Polar Regions is a complex task due to the extremely harsh environment. Mobile robots and robotic manipulators can aid research in these regions by performing tasks with automated precision, reducing the need for human involvement. Because most projects in these regions are labor-intensive, expensive in terms of time and cost, and possibly dangerous, autonomously performing such tas...

OBJECT The extent of resection (EOR) is a known prognostic factor in patients with glioblastoma. However, gross-total resection (GTR) is not always achieved. Understanding the factors that prevent GTR is helpful in surgical planning and when counseling patients. The goal of this study was to identify demographic, tumor-related, and technical factors that influence EOR and to define the relation...

We investigate the remote memory references (RMRs) complexity of deterministic processes that communicate by reading and writing shared memory in asynchronous cache-coherent and distributed shared-memory multiprocessors. We define a class of algorithms that we call order encoding. By applying information-theoretic arguments, we prove that every order encoding algorithm, shared by n processes, h...

Abstract We are concerned with a certain class of Schlömilch series that arise naturally in the study of diffraction problems when the scatterer is a periodic structure. By combining new results derived from integral representations and the Poisson summation formula with known identities, we obtain expressions which enable the series to be computed accurately and efficiently. Most of the techni...

Service-based applications have been attracting a lot of attention from both academia and industry in recent years. Therefore, as these applications need to operate in a highly dynamic and distributed world, they should adapt their behavior to ensure the expected functionality and quality. Many adaptation techniques have been proposed so far focusing on a single layer of the SBA life-cycle. In ...
