Recently, two major bankcard payment instrument operators VISA and MasterCard published speciications for securing bankcard payment transactions on open networks for open scrutiny. SEPP.) Based on their success in operating the existing on-line payment systems, both proposals use advanced cryptographic technologies to supply some security services that are well-understood to be inadequate in op...

A fundamental issue affecting the performance of a parallel application running on message-passing parallel systems is the assignment of tasks to processors in order to get the minimum completion time. In SEPP and HPCTI, tools for static and dynamic task assignment are considered complementary: static mapping tools compute and initial assignment of tasks on processors while dynamic load balanci...

OPS-SAT is the first publicly accessible Hardware/Software Innovation Lab in low Earth orbit. It was launched by European Space Agency on December 18, 2019, and open to academia industry, allowing new concepts be tested space with a range of interesting payloads. This article discusses implementation results an in-orbit demonstration (IOD) using software-defined radio payload together onboard R...

The biological systems are opened, complex objects, which can regularly exchange feedbacks with their environment. The calcium ion is a universal messenger, which can regulate several cellular functions e.g. exocytosis machinery. The primary aim of this study was to investigate the response mechanisms of normal adenohypophysis and adenohypophyseal prolactinoma cell populations at different extr...

Study of the dynamics and distribution of lepidopteran defoliators is important because some of them are major pests of eucalyptus. More than 3,000,000 ha of eucalyptus are now planted in Brazil even though the genus is not native there. The goal of this study was to document the frequency and constancy indexes of lepidopteran pests of Eucalyptus grandis Hill ex Maiden (Myrtaceae) collected wit...
