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)
We present a framework for monitoring enterprise wireless networks using desktop infrastructure. The framework is called DAIR, which is short for Dense Array of Inexpensive Radios. We demonstrate that the DAIR framework is useful for detecting rogue wireless devices (e.g., access points) attached to corporate networks, as well as for detecting Denial of(More)
Web-based enterprises process events generated by millions of users interacting with their websites. Rich statistical data distilled from combining such interactions in near real-time generates enormous business value. In this paper, we describe the architecture of Photon, a geographically distributed system for joining multiple continuously flowing streams(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)
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)
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.
Objectives: Pediatric bipolar disorder is characterized by core deficits in mood and executive function and commonly cooccurs 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)
Innovations in poultry processing include implementation of antimicrobials in post-chill decontamination tanks. In this study, a total of 160 broiler carcasses were analyzed to evaluate the efficacy of five post-chill water treatments consisting of 0.004% (40ppm) total chlorine, 0.04% (400ppm) or 0.1% (1000ppm) peracetic acid (PAA), and 0.1% (1000ppm) or(More)
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)
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)
