The effect of the choice of control allocation scheme upon individual control effector rate demands is examined. Three previously reported and one new variation of control allocation schemes are described and compared. The new allocation scheme exploits the maximum attainable moment-rates of a given control effector configuration and is called moment rate allocation. The bases of comparison are...

Untreated atrial fibrillation is usually associated with a rapid, irregular ventricular response and is often accompanied by symptoms including palpitations, fatigue, dyspnea, and dizziness. It is widely accepted that slowing the ventricular response, both at rest and during activity, with the use of drugs that prolong the refractory period of the atrioventricular (AV) node (so-called rate-cont...

Current congestion control mechanisms in today’s Internet rely on end-to-end TCP congestion avoidance algorithms that back off sources when congestion occurs, detected by packet loss or explicit congestion notification signals. But one of the major setbacks of such mechanisms is making sure that all sources respond correctly in applying congestion avoidance measures during periods of high conge...

Rate control plays an important role in video coding, although it’s not a normative tool for any video coding standard. In video communications, rate control must ensure the coded bitstream can be transmitted successfully and make full use of the limited bandwidth. As a consequence, a proper rate control scheme is usually recommended by a standard during the development, e.g. TM5 for MPEG-2, TM...

We provide the first differentially private algorithms for controlling the false discovery rate (FDR) in multiple hypothesis testing, with essentially no loss in power under certain conditions. Our general approach is to adapt a well-known variant of the Benjamini-Hochberg procedure (BHq), making each step differentially private. This destroys the classical proof of FDR control. To prove FDR co...

Control of the heart rate (rate control) is central to atrial fibrillation management, even for patients who ultimately require control of the rhythm. We review heart rate control in patients with atrial fibrillation, including the rationale for the intervention, patient selection, and the treatments available. The choice of rate control depends on the symptoms and clinical characteristics of t...

In this article, we propose a new single-rate end-to-end multicast congestion control scheme called Explicit Rate Multicast Congestion Control (ERMCC) based on a new metric, TRAC (Throughput Rate At Congestion). ERMCC can be implemented only at the source and the receivers of the multicast tree. ERMCC achieves an O(1) memory complexity to maintain state information at source and receivers; requ...

Flow and congestion control allow the users of a telecommunication network to regulate the traffic that they send into the network in accordance with the quality of service that they require. Flow control may be performed by the network, as is the case in asynchronous transfer mode (ATM) networks (the available bit rate (ABR) transfer capacity), or by the users themselves, as is the case in the...

Introduction and purpose: Cx43, most abundantly expressed in the ventricles, is engaged in forming both gap junctions that electrically couple the cardiac tissue and unapposed hemichannels (HCs) that function as a non-selective transmembrane conduit. The latter are typically closed but open in response to electrical or chemical triggers such as pro-inflammatory cytokines or elevation of cytopla...
