We consider a randomly diluted higher-order network with noise, consisting of McCulloch-Pitts neurons that interact by Hebbian-type connections. For this model, exact dynamical equations are derived and solved for both parallel and random sequential updating algorithms. For parallel dynamics, we find a rich spectrum of different behaviors including static retrieving and oscillatory and chaotic ...

A direct sequence (DS) spread spectrum code division multiple access (CDMA) communication system is considered where several users transmit data symbols over different multipath channels. The main objective of this work is the proposal of a sequential algorithm for joint parameter estimation and multiuser data detection. The computationally prohibitive maximization of the log-likelihood functio...

The Linac Coherent Light Source free electron laser is a source of high brightness x rays, 2×10(11) photons in a ∼5 fs pulse, that can be focused to produce double core vacancies through rapid sequential ionization. This enables double core vacancy Auger electron spectroscopy, an entirely new way to study femtosecond chemical dynamics with Auger electrons that probe the local valence structure ...

We introduce a new design style called extended burst-mode. The extended burst-mode design style covers a wide spectrum of sequential circuits ranging from delay-insensitive to synchronous. We can synthesize multiple-input change asynchronous finite state machines, and many circuits that fall in the gray area (hard to classify as synchronous or asynchronous) which are difficult or impossible to...

Fast and high precision relative GPS positioning based on short observation time span data is possible, when reliable estimates of the integer double difference ambiguities can be determined in an efficient manner. In the present contribution it will be shown how this can be achieved by means of the Least-squares AMBiguity Decorrelation Adjustment (LAMBDA). The method was introduced in [Teuniss...

The study of irradiation-induced defects on the nanoscale is crucial for a fundamental understanding of displacement and implantation damage in various microstructures. Ion irradiation performed in situ inside of a TEM is a unique tool allowing direct observation of defect evolution on nanometer length scales in real time [1]. Most facilities use a single ion beam, but in many real radiation en...

Background: Microbiota have evolved to acclimate themselves to many environments. Humanity is become ever increasingly medicated and many of those medications are antibiotics. Sadly, Microbiota are adapting to medication and with each passing generation they become more difficult to subdue. The 16S small subunit of bacterial ribosomal rRNA provides a wealth of information for classifying the sp...

We explore the following quintessential problem: given a set of basic computing elements how do we compose them to yield desired computation patterns. Our goal is to study composition operators which apply across a broad spectrum of computing elements, from sequential programs to distributed transactions over computer networks. Our theory makes very few assumptions about the nature of the basic...

The Generalized Pólya Urn (GPU) is a popular urn model which is widely used in many disciplines. In particular, it is extensively used in treatment allocation schemes in clinical trials. In this paper, we propose a sequential estimation-adjusted urn model (a nonhomogeneous GPU) which has a wide spectrum of applications. Because the proposed urn model depends on sequential estimations of unknown...

In direct-sequence wideband (DS-WB) systems, long spreading sequences are used to span multiple symbol intervals in order to remove spectral lines and to mitigate multiple access interference. The usage of long spreading sequences will result in a large search space during acquisition stage. As a result, the DS-WB systems will need a lot of time to achieve acquisition state. This paper proposes...
