The ORBIT (Open Access Research Testbed for Next- Generation Wireless Networks) testbed project which aims to provide a flexible, open-access multiuser experimental facility to support research on next-generation wireless networks is presented in this paper. ORBIT measurement overlay framework is used for experiment statistics in a type-safe manner.(More)
• Scale of WLAN – Microsoft's WLAN has over 5000 APs • Need to deploy many monitors – Rapid fading of signal in indoor environment – Multiple orthogonal channels – May need observations from multiple vantage points Š Pinpoint location of rogue AP • Eavesdropping – Passive snooping (perhaps with high-gain antennas) – Nearly impossible to detect –(More)
CONTEXT Deficits in reward processing and their neural correlates have been associated with major depression. However, it is unclear if these deficits precede the onset of depression or are a consequence of this disorder. OBJECTIVE To determine whether anomalous neural processing of reward characterizes children at familial risk for depression in the(More)
Accurate identification of sparse heterozygous single-nucleotide variants (SNVs) is a critical challenge for identifying the causative mutations in mouse genetic screens, human genetic diseases and cancer. When seeking to identify causal DNA variants that occur at such low rates, they are overwhelmed by false-positive calls that arise from a range of(More)
This paper presents the software architecture of the ORBIT radio grid testbed. We describe the requirements for supporting the lifecycle of an experiment and how they influenced the overall design of the architecture. We specifically highlight those components and services which will be visible to a user of the ORBIT testbed.
We present a framework for managing and troubleshooting enterprise wireless networks using desktop infrastructure. The framework is called DAIR, which is short for Dense Array of Inexpensive Radios. Prior proposals in this area include monitoring the network via a combination of access points (APs), mobile clients, and dedicated sensor nodes. We believe(More)
BACKGROUND AND OBJECTIVES Acute kidney injury (AKI) occurs commonly after cardiac surgery. Most patients who undergo cardiac surgery receive long-term treatment with angiotensin-converting enzyme inhibitors (ACEI) or angiotensin II receptor blockers (ARB). The aim of this study was to determine whether long-term use of ACEI/ARB is associated with an(More)
Objectives: Pediatric bipolar disorder is characterized by core deficits in mood and executive function and commonly co-occurs with attention-deficit=hyperactivity disorder (ADHD). We aimed to examine response inhibition in this population, as an element of executive function, which, if aberrant, may interfere with learning and information processing.(More)
OBJECTIVES Pediatric bipolar disorder (BPD) and attention-deficit hyperactivity disorder (ADHD) co-occur more frequently than expected by chance. In this review, we examine 4 potential explanations for the high rate of this common co-occurrence: (i) BPD symptom expression leads to overdiagnosis of ADHD in BPD youth; (ii) ADHD is a prodromal or early(More)
OBJECTIVE To examine structural differences in selected anterior limbic brain regions between at-risk children of parents with bipolar I disorder and children with healthy parents. We hypothesized that at-risk (AR) children would exhibit abnormalities in brain regions that are involved in mood regulation. METHOD Children (8-12 years old) of parents with(More)
