Vital hypothalamic neurons regulating hunger, wakefulness, reward-seeking, and body weight are often defined by unique expression of hypothalamus-specific neuropeptides. Gene-ablation studies show that some of these peptides, notably orexin/hypocretin (hcrt/orx), are themselves critical for stable states of consciousness and metabolic health. However, neuron-ablation studies often reveal more s...

In this paper, the parallel multiple access channel (MAC) is studied under the assumption that transmitters maximize their individual spectral efficiency by selfishly tuning their power allocation policy. Two particular scenarios are studied: (a) transmitters are allowed to use all the available channels; and (b) transmitters are constrained to use a single channel. Both scenarios are modeled b...

This article examines methods for and results of determining the instantaneous kinematic state a target, i.e., its velocity heading, using passive multistatic radar. is achieved by combining bistatic target range Doppler information obtained multiple transmitter-receiver pairs, to estimate appropriate vector. estimation provided as set closed-form equations, derived general case applicable an a...

We consider a generalization of the classical Art Gallery Problem, where instead of a light source, the guards, called k-transmitters, model a wireless device with a signal that can pass through at most k walls. We show it is NP-hard to compute a minimum cover of point 2transmitters, point k-transmitters, and edge 2-transmitters in a simple polygon. The point 2transmitter result extends to orth...

The paper describes a 3D acoustic imaging system that uses a 2D receiver array and a 2D transmitter array. For many years, high quality acoustic imaging has been achieved by using synthetic transmit aperture (STA) technique [1][2]. Normally, STA uses an array of receivers and a small number of transmitters to produce an image. However, the conventional arrangement of transmitters in a same hori...

We investigated the levels of radio frequency electromagnetic fields (RF EMFs) emitted from marine ship transmitters. In this study, we recorded the radio frequency (RF) electric field (EF) levels emitted from transmitters from a marine vessel focusing on the areas normally occupied by crew members and passengers. Previous studies considered radiation hazard safety assessment for marine vessels...

We consider a visible light positioning system in which receiver performs position estimation based on signals emitted from number of emitting diode (LED) transmitters. Each LED transmitter can be malicious and transmit at an unknown power level with certain probability. A maximum likelihood (ML) estimator is derived the knowledge probabilities that transmitters malicious. In addition, presence...
