Bird song and territorial defensive behavior have intraand inter-sexually selected functions (Andersson 1994; Catchpole & Slater 1995). For a sexually selected signal to be an honest indicator of quality, it may be costly (Zahavi 1975; Searcy & Yasukawa 1996; but see Vehrencamp 2000). Song bouts may take time away from foraging (Searcy & Yasukawa 1996), and may also increase predation risk (Gil...

Target recognition systems using Synthetic Aperture Radar (SAR) data require well-focused target imagery to achieve high probability of correct classification. Techniques for improving the image quality of complex SAR imagery are investigated. The application of phase gradient re-focusing of target imagery having crossrange smearing is shown to significantly improve the target recognition perfo...

BACKGROUND The Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act1 (“Hawkins-Slater”– Rhode Island General Laws 21-28.6-1) became law in 2005. Regulations2 were promulgated initially in July of 2006. The legislative findings3 incorporated in Hawkins-Slater assert that modern medical research recognizes beneficial uses for marijuana, including the treatment of pain, nausea and other de...

Tunneling anisotropic magnetoresistance in a magnetic tunnel junction with half-metallic electrodes" (2016). Evgeny Tsymbal Publications. 53. Tunneling anisotropic magnetoresistance (TAMR) is the difference in resistance of a magnetic tunnel junction due to a change in magnetization direction of one or both magnetic electrodes with respect to the flow of current. We present the results of first...

Excited states of the s, p, and d symmetries up to principal quantum number n = 4 are studied for the first eight members of Ne isoelectronic sequence (Ne to Cl) by the SAC-CI (symmetry-adaptedcluster configuration-interaction) method. The valence STO basis sets of Clementi et al. and the optimized excited STO are used by the STO-6G expansion method. The calculated transition energies agree wel...

Although embedded training has become the preferred approach for training military forces, it is surrounded by a variety of technical challenges. The Inter-Vehicle Embedded Science and Technology (INVEST) Science and Technology Objective (STO) program explores technologies required to embed simulation in combat vehicles. One of these requirements is to provide a simulation environment in which ...

Mixed mode oscillations (MMO’s) composed of subthreshold oscillations (STO’s) and spikes appear via a variety of mechanisms in models of neural dynamics. Two key elements that can influence the prominence of the STO’s are multiple time scales and time varying parameters near critical points. These features can lead to dynamics associated with bifurcation delay, and we consider three systems wit...

Filter bank multicarrier systems, similarly to orthogonal frequency division multiplexing (OFDM), are very sensitive to carrier frequency offset (CFO) and symbol timing offset (STO). In this paper, a low-complexity preamble-based joint CFO and STO technique is presented. It is based on a relatively long preamble in order to improve the CFO estimation performance as well as avoid interference co...

We propose a novel power efficient adaptive hybrid dynamic power management (AH-DPM) algorithm. To adapt well to bursty request arrival patterns with self-similarity and a service provider (SP, i.e., hard disk or WLAN NIC, in this paper) with multiple inactive states, the proposed AH-DPM first derives the average idle time of the SP in the bursty (ON) period and non-bursty (OFF) period separate...
