Modern networks provide a variety of interrelated services including routing, traffic monitoring, load balancing, and access control. Unfortunately, the languages used to program today's networks lack modern features - they are usually defined at the low level of abstraction supplied by the underlying hardware and they fail to provide even rudimentary(More)
The ENCyclopedia Of DNA Elements (ENCODE) Project aims to identify all functional elements in the human genome sequence. The pilot phase of the Project is focused on a specified 30 megabases (È1%) of the human genome sequence and is organized as an international consortium of computational and laboratory-based scientists working to develop and apply(More)
Software-defined networks (SDNs) are a new kind of network architecture in which a controller machine manages a distributed collection of switches by instructing them to install or uninstall packet-forwarding rules and report traffic statistics. The recently formed Open Networking Consortium, whose members include Google, Facebook, Microsoft, Verizon, and(More)
Most interfaces for programming network devices are defined at the low level of abstraction supported by the underlying hardware, which leads to complicated programs that are prone to errors. This paper proposes a high-level programming language for OpenFlow networks based on ideas originally developed in the functional programming community. Our language,(More)
6 This review on research on life cycle carbon accounting examines the complexities in accounting for carbon emissions given the many different ways that wood is used. Recent objectives to increase the use of renewable fuels have raised policy questions, with respect to the sustainability of managing our forests as well as the impacts of how best to use(More)
Visual hallucinations (VH) are a core feature of dementia with Lewy bodies (DLB), but little is known about their phenomenology. A total of 73 dementia patients (42 DLB, 30 Alzheimer's disease [AD], 1 undiagnosed) in contact with clinical services were assessed with a detailed standardized inventory. DLB was diagnosed according to the criteria of McKeith(More)
—Modern computer networks perform a bewildering array of tasks, from routing and traffic monitoring, to access control and server load balancing. Yet, managing these networks is unnecessarily complicated and error-prone, due to a heterogeneous mix of devices (e.g., routers, switches, firewalls, and middleboxes) with closed and proprietary configuration(More)
The study aimed to evaluate the merits of the Unified Parkinson's Disease Rating Scale (UPDRS) in the assessment of parkinsonism in patients suffering from Dementia with Lewy Bodies (DLB). Parkinsonian symptoms were assessed in 73 dementia patients using the UPDRS and staged using the Hoehn & Yahr system. A staging of 1 or greater was taken to indicate(More)
