Optimal Jammer Placement in Wireless Localization Systems [PDF]

, 2016
In this study, the optimal jammer placement problem is proposed and analyzed for wireless localization systems. In particular, the optimal location of a jammer node is obtained by maximizing the minimum of the Cramer-Rao lower bounds (CRLBs) for a number of target nodes under location related constraints for the jammer node.

Recursive, parameter-free, explicitly defined interpolation nodes for simplices [PDF]

arXiv, 2020
A rule for constructing interpolation nodes for $n$th degree polynomials on the simplex is presented. These nodes are simple to define recursively from families of 1D node sets, such as the Lobatto-Gauss-Legendre (LGL) nodes. The resulting nodes have attractive properties: they are fully symmetric, they match the 1D family used in construction on the ...

Catheter Ablation of Parahisian Premature Ventricular Complexes From the Right Sinus of Valsalva

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Cather ablation of parahisian premature ventricular complexes (PVCs) often requires ablation in multiple cardiac chambers, including the sinuses of Valsalva (SoV). The safety and efficacy of ablation within the right SoV to target parahisian arrhythmias has not been widely reported.

Efficacy and safety of etrasimod in alopecia areata: A multicentre, randomized, double‐blind, placebo‐controlled, Phase 2 study

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Patients with alopecia areata received etrasimod 2 mg, 3 mg or placebo oncedaily for 24 weeks, followed by a 28‐week open‐label extension period. Overall, etrasimod 2 mg and 3 mg were safe and well tolerated in patients; their efficacy was numerically higher than placebo and appeared to be dose dependent.

Posterior fast atrioventricular node pathways: Implications for radiofrequency catheter ablation of atrioventricular node reentrant tachycardia

Journal of the American College of Cardiology, 1996
This study sought to present evidence that fast atrioventricular (AV) node pathways with posterior exit sites may participate in typical AV node reentry.Catheter ablation of the slow AV node pathway in the posteroseptal right atrium is the preferred therapeutic approach in patients with AV node reentrant tachycardia.

Artificial Cardiac Conduction System: Simulating Heart Function for Advanced Computational Problem Solving [PDF]

arXiv
This work proposes a novel bio-inspired metaheuristic called Artificial Cardiac Conduction System (ACCS) inspired by the human cardiac conduction system. The ACCS algorithm imitates the functional behaviour of the human heart that generates and sends signals to the heart muscle, initiating it to contract.

Identifying Cheating Anchor Nodes using Maximum Likelihood and Mahalanobis Distance [PDF]

arXiv, 2014
Malicious anchor nodes will constantly hinder genuine and appropriate localization. Discovering the malicious or vulnerable anchor node is an essential problem in Wireless Sensor Networks (WSNs). In wireless sensor networks, anchor nodes are the nodes that know its current location.

2:1 Atrioventricular Block During Atrioventricular Node Reentrant Tachycardia

Journal of the American College of Cardiology, 1996
The purpose of this study was to determine the incidence and to clarify the mechanism of 2:1 atrioventricular (AV) block during AV node reentrant tachycardia induced in the electrophysiology laboratory.In patients with 2:1 AV block during AV node reentrant tachycardia, the absence of a His bundle potential in the blocked beats has been considered ...

Role of epicardial adipose tissue in heart failure with preserved ejection fraction: An emerging molecular mechanism and therapeutic potential

Obesity Reviews, EarlyView.
Summary With the evolving landscape of diseases, heart failure with preserved ejection fraction (HFpEF) now encompasses more than half of all heart failure patients. This condition is clinically diverse, involving multiple organ systems and often occurring alongside the aging process.
