Transparent Incremental Updates for Genomics Data Analysis Pipelines
(Chapter; Bokkapittel, 2014)A large up-to-date compendium of integrated genomic data is often required for biological data analysis. The compendium can be tens of terabytes in size, and must often be frequently updated with new experimental or meta-data. Manual compendium update is cumbersome, requires a lot of unnecessary computation, and it may result in errors or inconsistencies in the compendium. We propose a transparent ... -

An Evaluation Framework for Defining the Contributions of Telestration in Surgical Telementoring
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Background: An increasing quantity of research in the domain of telemedicine show a growing popularity and acceptance of care over distance systems among both clinicians and patients. We focus on telementoring solutions, developed for providing remote guidance to less experienced surgeons. Telestration is often regarded as an extra functionality of some telementoring systems. However, we advocate ... -

The Nornir run-time system for parallel programs using Kahn process networks on multi-core machines-a flexible alternative to MapReduce
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Even though shared-memory concurrency is a paradigm frequently used for developing parallel applications on small- and middle-sized machines, experience has shown that it is hard to use. This is largely caused by synchronization primitives which are low-level, inherently non-deterministic, and, consequently, non-intuitive to use. In this paper, we present the Nornir run-time system. Nornir is ... -
Functional Knowledge Transfer for High-accuracy Prediction of Under-studied Biological Processes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)A key challenge in genetics is identifying the functional roles of genes in pathways. Numerous functional genomics techniques (e.g. machine learning) that predict protein function have been developed to address this question. These methods generally build from existing annotations of genes to pathways and thus are often unable to identify additional genes participating in processes that are not ... -
Model-driven diabetes care: study protocol for a randomized controlled trial
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Background: People with type 1 diabetes who use electronic self-help tools register a large amount of information about their disease on their participating devices; however, this information is rarely utilized beyond the immediate investigation. We have developed a diabetes diary for mobile phones and a statistics-based feedback module, which we have named Diastat, to give data-driven feedback ... -
Telehealth at UC Davis—A 20-Year Experience
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Telehealth at the University of California Health System began as a telefetal monitoring connection with a rural hospital in 1992 and evolved to become the Center for Health and Technology (CHT) in 2000. The Center supports the vision of the University of California Davis (UC Davis) Health System—a healthier world through bold innovation. The CHT focuses on the four pillars of the academic ... -
Omni-Kernel: An Operating System Architecture for Pervasive Monitoring and Scheduling
(Research report; Forskningsrapport, 2013)Clouds commonly employ virtual machine technology to leverage and efficiently utilize computational resources in data centers. The workloads encapsulated by virtual machines contend for the resources of their hosting machines, and interference from resource sharing can cause unpredictable performance. Despite the use of virtual machine technology, the role of the operating system as an arbiter of ... -
DeltaTree: A Practical Locality-aware Concurrent Search Tree
(Research report; Forskningsrapport, 2013)As other fundamental programming abstractions in energy-e cient computing, search trees are expected to support both high parallelism and data locality. However, existing highly-concurrent search trees such as red-black trees and AVL trees do not consider data locality while existing locality-aware search trees such as those based on the van Emde Boas layout (vEB-based trees), poorly support ... -
Physicians Interrupted by Mobile Devices in Hospitals: Understanding the Interaction Between Devices, Roles, and Duties
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)A common denominator of modern hospitals is a variety of communication problems. In particular, interruptions from mobile communication devices are a cause of great concern for many physicians. Objective: To characterize how interruptions from mobile devices disturb physicians in their daily work. The gathered knowledge will be subsequently used as input for the design and development of a ... -
Muithu: Smaller Footprint, Potentially Larger Imprint
(Research report; Forskningsrapport, 2012)We describe our experience with the Muithu sports notational analysis system, a novel digital information system in the popular sports domain. The system integrates real-time coach notations with related video sequences, and is configured with small, off-the shelf and cheap components. Muithu requires little or no human post-processing, which is in strong contrast to state-of-the art resource-intensive ... -
HealthTrust: A Social Network Approach for Retrieving Online Health Videos
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Background: Social media are becoming mainstream in the health domain. Despite the large volume of accurate and trustworthy health information available on social media platforms, finding good-quality health information can be difficult. Misleading health information can often be popular (eg, antivaccination videos) and therefore highly rated by general search engines. We believe that community ... -
Improving Diabetes Care for Young People With Type 1 Diabetes Through Visual Learning on Mobile Phones: Mixed-Methods Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Background: Only 17% of Norwegian children and adolescents with diabetes achieve international treatment goals measured by glycated hemoglobin (HbA1c). Classic patient–physician consultations seem to be poorly adapted to young children. New strategies that are better attuned to young people to improve support of adolescents’ self-management of diabetes need to be tested and evaluated. Objective: ... -
Pro-Anorexia and Pro-Recovery Photo Sharing: A Tale of Two Warring Tribes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)There is widespread use of the Internet to promote anorexia as a lifestyle choice. Pro-anorexia content can be harmful for people affected or at risk of having anorexia. That movement is actively engaged in sharing photos on social networks such as Flickr. Objective: To study the characteristics of the online communities engaged in disseminating content that encourages eating disorders (known as ... -
IMP: a multi-species functional genomics portal for integration, visualization and prediction of protein functions and networks
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Integrative multi-species prediction (IMP) is an interactive web server that enables molecular biologists to interpret experimental results and to generate hypotheses in the context of a large cross-organism compendium of functional predictions and networks. The system provides a framework for biologists to analyze their candidate gene sets in the context of functional networks, as they expand or ... -
Experimental Fault-Tolerant Synchronization for Reliable Computation on Graphics Processors
(Research report; Forskningsrapport, 2012)Graphics processors (GPUs) are emerging as a promising platform for highly parallel, compute-intensive, general-purpose computations, which usually need support for inter-process synchronization. Using the traditional lock-based synchronization (e.g. mutual exclusion) makes the computation vulnerable to faults caused by both scientists’ inexperience and hardware transient errors. It is notoriously ... -
Mobile Phone-Based Pattern Recognition and Data Analysis for Patients with Type 1 Diabetes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Persons with type 1 diabetes who use electronic self-help tools, most commonly blood glucose meters, record a large amount of data about their personal condition. Mobile phones are powerful and ubiquitous computers that have a potential for data analysis, and the purpose of this study is to explore how self-gathered data can help users improve their blood glucose management. Thirty patients with ...
