In this first investigation of the MOCCA database with respect to cataclysmic variables, we found that for models with Kroupa initial distributions, considering the standard value of the efficiency of the common-envelope phase adopted in BSE, no single cataclysmic variable was formed only via binary stellar evolution, i. e., in order to form them, strong dynamical interactions have to take place.
For patients with end-stage heart failure, the use of mechanical circulatory support has increased in the last decade due to improved outcomes with durable left ventricular assist devices. The management of these complex patients requires coordinated care by a multidisciplinary team including cardiac electrophysiologists because atrial and ventricular arrhythmias are prevalent in this population.
This paper presents theory and algorithms for validation in system identification of state-space models from finite input-output sequences in a subspace model identification framework. Similar to the case of prediction-error identification, it is shown that the resulting model can be decomposed into an input-output model and a stochastic innovations model. Using the Riccati equation, we have desig
In this paper, we investigate the problem of finding housing for refugees once they have been granted asylum. In particular, we demonstrate that market design can play an important role in a partial solution to the problem. More specifically, we investigate a specific matching system, and we propose an easy‐to‐implement mechanism that finds an efficient, stable, and maximum matching. Such a matchi
A feed-forward neural network method is developed for reconstructing the invariant mass of hadronic jets appearing in a calorimeter. The approach is illustrated in W→qq, where W-bosons are produced in pp reactions at SPS collider energies. The neural network method yields results that are superior to conventional methods. This neural network application differs from the classification ones in the
The response of excitatory amino acid transporter binding sites in the rat brain to 10 min of cerebral ischemia induced by bilateral common carotid occlusion combined with hypotension was examined. We observed a transient increase in the density of transporter binding sites that was first noticeable at 5 min post-recovery and persisted for 48 h. The increase in binding sites was found throughout t
Is attention a purely perceptual process or is it in any way related to motor control? The aim of this article is to show that attention puts similar demands on a cognitive system as motor control and present evidence supporting the view that similar mechanisms operate in the two processes. A computational model of attention is presented that uses habituation as well as classical and instrumental
A numerical implementation of a method to analyze scattering by randomly located obstacles in a slab geometry is presented. In general, the obstacles can be of arbitrary shape, but, in this first implementation, the obstacles are dielectric spheres. The coherent part of the reflected and transmitted intensity at normal incidence is treated. Excellent agreement with numerical results found in the l
We show how to minimize the asymptotic variance of multipower estimators using a linear combination of optimal powers. Taking advantage of the lower variance provided by this technique allows to build superior estimators of integrated volatility powers. In particular, we focus on a new efficient quarticity estimator and we show, using simulated data, that we can drastically reduce the mean square
