We study spillovers between REITs and stock markets in a global context. compute both directional net spillover indexes dynamic setting. use LASSO methods to include many our analysis. Our findings indicate that connectedness these is high. On average three REIT one market are volatility transmitters. Considerable time variation observed. Spillovers substantially higher during crises. While wer...

At ICAD'96, a real-time virtual audio reality model was presented, which included model-based sound synthesizers, geometric room acoustics modeling, binaural auralization for headphone and loudspeaker listening, and high-quality animation. The DIVA environment is an integrated implementation of a virtual reality system currently aiming at a virtual symphony orchestra performance. In the current...

Spectrally Efficient FDM (SEFDM) systems employ non-orthogonal overlapped carriers to improve spectral efficiency for future communication systems. One of the challenges for SEFDM systems is to demonstrate efficient hardware implementations for transmitters and receivers. This paper presents the first VLSI digital baseband transmitter architecture for SEFDM. The transmitter is reconfigurable be...

Widely-tunable lasers have gained much attention over the past few years as universal sources for dense WDM networks[1]. Interest in the dynamic networking capability enabled by such sources is also of continued interest, although the slow-down in the build out of the telecom infrastructure has slowed the introduction of such architectures. In this paper we will review the current status of InP...

This paper proposes and verifies a SAR measurement procedure for a multi-antenna transmitter that requires the measurement of two-dimensional electric field distributions for the number of antennas and the calculation for obtaining the three-dimensional SAR distributions for arbitrary weighting coefficients of the antennas prior to determining the average SAR. The proposed procedure is verified...

A k-transmitter in a simple orthogonal polygon P is a mobile guard that travels back and forth along an orthogonal line segment s inside P . The k-transmitter can see a point p ∈ P if there exists a point q ∈ s such that the line segment pq is normal to s and pq intersects the boundary of P in at most k points. In this paper, we give a 2-approximation algorithm for the problem of guarding a mon...

Activation of the pacemaker ("funny," I(f)) current during diastole is the main process underlying generation of the diastolic depolarization and spontaneous activity of cardiac pacemaker cells. I(f) modulation by autonomic transmitters is responsible for the chronotropic regulation of heart rate. Given its role in pacemaking, I(f) has been a major target of investigation aimed to exploit its r...

The enough complexity to exhibit both aspects of a multiaccess framework is information-theoretic; nonetheless it also incorpo-problem. In the analysis we use tools borrowed from both rates some queuteing-theoretic aspects of the problem....
