During speech listening, the brain parses a continuous acoustic stream of information into computational units (e.g., syllables or words) necessary for speech comprehension. Recent neuroscientific hypotheses have proposed that neural oscillations contribute to speech parsing, but whether they do so on the basis of acoustic cues (bottom-up acoustic parsing) or as a function of available linguist...

Bottom-up proteomics relies on the use of proteases and is the method of choice for identifying thousands of protein groups in complex samples. Top-down proteomics has been shown to be robust for direct analysis of small proteins and offers a solution to the "peptide-to-protein" inference problem inherent with bottom-up approaches. Here, we describe the first large-scale integration of genomic,...

Aggregated curves are common structures in economics and finance, the most prominent examples supply demand curves. In this study, we exploit fact that all aggregated have an intrinsic hierarchical structure, thus reconciliation methods can be used to improve forecast accuracy. We provide in-depth theory on how constructed or deconstructed, conclude these equivalent under weak assumptions. cons...

discrimination of objects using cues derived from object interposition. We construct a model of object segmentation using hybrid neural networks—distributed parallel systems consisting of neural units modeled at different levels af abstraction. We show that such networks are particularly useful for systems which can be modeled using the combined top-down/bottom-up approach. Our hybrid mod...

The restauration and preservation of ancient documents is becoming an interesting application in document image analysis. This paper introduces a top-down approach aimed at segmenting the graphical part in historical heritage called lettrine. The research principle was established on the concept of human visual perception and invariant texture analysis (co-occurrence and run-length matrices, au...

In this paper, a smart and simple algorithm is presented for Indian vehicle's license plate recognition system This introductory paper describes the need of Indian license plate detection, recognition system, Indian license plate characters, Structure of Indian License plates, and License Plate image pre-processing methodologies. For extracting the license plate methods and such as to dete...
