Abstract— Recently TCP/RED networks are shown to exhibit a rich set of nonlinear behaviors, leading to instabilities. In order to address some of these issues Floyd et al. have proposed an adaptive version of RED, named ARED. In this paper we analytically demonstrate that ARED has some desirable properties compared to RED. First, we show that the stability of the ARED does not depend on the net...

In this paper we compare the three Active Queue Managements (AQMs) Adaptive Random Early Detection (ARED), Controlled Delay (CoDel) and Proportional Integral controller Enhanced (PIE) in static as well as dynamic scenarios. We find significant issues when these algorithms are used for big Round Trip Times (RTTs) as well as a significant utilization decrease when used for high bandwidth links. W...

BACKGROUND Participation rates in colorectal cancer screening (CRC) are low. Relatively little is known about screening uptake across varying levels of risk and across population groups. The purpose of the current study was to identify factors associated with (i) ever receiving colorectal cancer (CRC) testing; (ii) risk-appropriate CRC screening in accordance with guidelines; and (iii) recent c...

Patients at risk for lung cancer may have subclinical disease for years before presentation. The diagnosis of this disease is primarily based on symptoms, and detection often occurs after curative intervention is no longer possible. At present, no lung cancer early-detection biomarker is clinically available. This study reviews the most recent advances in early detection and molecular diagnosti...

Many problems require making sequential decisions. For these problems, the benefit of acquiring further information must be weighed against the costs. In this paper, we describe the catenary support vector machine (catSVM), a margin-based method to solve sequential stopping problems. We provide theoretical guarantees for catSVM on future testing examples. We evaluated the performance of catSVM ...

The Random early detection (RED) active queue management (AQM) scheme uses the average queue size to calculate the dropping probability in terms of minimum and maximum thresholds. The effect of heavy load enhances the frequency of crossing the maximum threshold value resulting in frequent dropping of the packets. An adaptive queue management with random dropping (AQMRD) algorithm is proposed wh...

Random Early Detection (RED) has been introduced as a congestion avoidance algorithm for the Internet. RED detects congestion by estimating the average queue size. It drops packets probabilistically before buuer overrow, with the drop probability depending on the average queue size. In this paper, we analyse the innuence of RED on the packet loss ratio and the throughput of a system consisting ...

OBJECTIVES Human papillomavirus self-tests that can be used at home and returned by mail may increase cervical cancer screening rates. Growing evidence suggests that self-test methods could increase screening for high-risk and hard-to-reach populations. The purpose of this study was to identify which self-test device women prefer and why. METHODS Four focus groups were conducted with 30 high-...

BACKGROUND In the years 2014, coverage rates of cervical cancer screening in Nakornnayok province accounted to 76.5%. This was lower than the government's specified goal of 80%. Community health volunteers are members of a Thai healthcare alliance established to help promoting healthcare service communication and collaboration at the primary level. Such village health volunteers (VHVs) are esta...
