Attention-deficit/hyperactivity disorder is a common neurobehavioral disorder of childhood and adolescence. The etiology of attention-deficit/hyperactivity disorder is not well understood. Neurochemical studies suggest, alterations in catecholaminergic, mainly dopaminergic and noradrenergic, transmitter functions markedly contribute to the symptoms of this disorder. The symptoms of attention-de...

Recent efforts to increase online privacy by offering the user a more general choice to opt out of online tracking were mainly pushed by the FTC in late 2010. As the FTC explicitly omitted technical details, browser developers started to implement what they thought might be appropriate to either limit user tracking directly, or let the advertiser know about the user’s wish to not be tracked. Th...

2. Do I hold in my hand the truly appropriate remedy for that lack ? 3. Is the preparation stable, active, pure, and uniform ? 4. Can I accurately determine the dosage ? 5. Is the preparation smoothly active when administered by the route I propose ? 6. Are ill-effects impossible ? Even if these questions cannot be answered in the affirmative, he gives the prescriber one more chance, provided t...

In order to explain how DIYbio knowledge and expertise is developed and shared the use of Practice Theory will help us gain a useful understanding of how working practices are sustained, reproduced and potentially changed. In addition, the development and sharing of thick, evocative, rich descriptions of these practices might contribute to the motivational knowledge of DIYbio practitioners.

DO-178B was based on the consensus of the avionic software community as it existed in 1992. Twenty two years after publication, we have no publically available experimental data as to its efficacy. It appears to work extremely well, since there have been no hull loss accidents in passenger service ascribed to software failure. This is a comforting and surprising result. However, if we don’t kno...

One key step in the development of safety-critical applications is the assessment of the quality of the verification strategy. In practice, structural coverage is the methodology used to ascertain the testing campaign well satisfy a given quality criteria. In this paper, we describe the possible strategies to measure structural coverage in a DO-178B context. After evaluating state-ofthe-art app...

Introduction This whitepaper describes how the VectorCAST embedded software testing platform is used to satisfy the Software Verification Process objectives as defined in section 6.0 of the DO-178B and DO-178C standards, “Software Considerations in Airborne Systems and Equipment Certification.” This whitepaper also highlights the differences between the two standards as they relate to Section 1...

For about two decades, compliance with Software Considerations in Airborne Systems and Equipment Certification (DO-178B) has been the primary means for receiving regulatory approval for using software on commercial airplanes. A new edition of the standard, DO-178C, was published in December 2011, and regulatory bodies have started the process towards recognizing this edition. The stated purpose...

OBJECTIVE To investigate hematologic variables related to iron deficiency and food intake in attention-deficit/hyperactivity disorder. METHOD The sample comprised 62 children and adolescents (6-15 years old) divided into three groups: Group 1: 19 (30.6%) patients with attention-deficit/hyperactivity disorder using methylphenidate for 3 months; Group 2: 22 (35.5%) patients with attention-defic...
