Abstract: A practically implementable robust direction-of-arrival (DoA) estimation approach that is resistant to localization errors due to mobility, multipath reflections, impulsive noise, and multiple-access interference. As part of the disclosed invention the inventors consider infrastructure-less 3D localization of autonomous underwater vehicles (AUVs) with no GPS assistance and no availability of global clock synchronization. The proposed method can be extended to challenging communication environments and applied for the localization of assets/objects in space, underground, intrabody, underwater and other complex, challenging, congested and sometimes contested environments. Each AUV leverages known-location beacon signals to self-localize and can simultaneously report its sensor data and measurement location.

Abstract: Novel cyclic peptides, cyclic peptide conjugates and compositions containing them for treating neurological diseases in a subject include an Odorranalectin (OL) sequence or modified OL sequence as a scaffold and a biologically active peptide or protein and/or therapeutic agent conjugated thereto. Methods of treatment of neurological diseases are based on intranasal delivery of a cyclic peptide or cyclic peptide conjugate as described herein. Combinatorial libraries that include a plurality of cyclic peptides have also been developed and can be used to screen for a ligand(s) for a receptor of interest.

Abstract: The present invention is directed to systems and methods designed to ascertain the structure of acoustic signals. The approach involves an alternative transform of an acoustic input signal, utilizing a network of nonlinear oscillators in which each oscillator is tuned to a distinct frequency. Each oscillator receives input and interacts with the other oscillators in the network, yielding nonlinear resonances that are used to identify structure in an acoustic input signal. The output of the nonlinear frequency transform can be used as input to a system that will provide further analysis of the signal. According to one embodiment, the nonlinear responses are defined as a network of n expanded canonical oscillators zi, with an input, for each oscillator as a function of an external stimulus. In this way, the response of oscillators to inputs that are not close to its natural frequency are accounted for.
