The paper suggests a generalisation of the diffusion-limited aggregation (DLA) based on using a general stochastic process to control particle movements before sticking to a growing cluster. This leads to models with variable characteristics that can provide a single framework for treating a number of earlier models of fractal growth: the DLA, the Eden model and the ballistic aggregation. Addit...

Fisher’s linear discriminant analysis (LDA), one of the most popular dimensionality reduction algorithms for classification, has three particular problems: it fails to find the nonlinear structure hidden in the high dimensional data; it assumes all samples contribute equivalently to reduce dimension for classification; and it suffers from the matrix singularity problem. In this paper, we propos...

BACKGROUND Epidemiologic studies require identification or typing of microbial strains. Macrorestriction DNA mapping analyzed by pulsed-field gel electrophoresis (PFGE) is considered the current gold standard of genomic typing. This technique, however, is difficult to implement because it is labor-intensive and difficult to automate, it requires a long time to obtain results, and results often ...

Dogs given nonmyeloablative conditioning and marrow grafts from 2 dog leukocyte antigen (DLA)-identical littermate donors developed stable trichimerism and stably accepted a subsequent kidney graft from one of the marrow donors without the need for immunosuppression. In this study, we used trichimeras to evaluate strategies for adoptive immunotherapy to solid tumors, using the kidney as a tumor...

Class-II histocompatibility genes are associated with predisposition to autoimmune diseases in many mammal species. We have developed a technique using reverse transcriptase and nested-PCR for amplification from blood samples of expressed sequences encoded by canine DLA-DRB1 loci. In the first polymerase chain reaction (PCR), we utilize primers DR-SP and DR-STOP as developed by Sarmiento et al....

This paper presents the design and implementation of several fundamental dense linear algebra (DLA) algorithms for multicore with Intel Xeon Phi Coprocessors. In particular, we consider algorithms for solving linear systems. Further, we give an overview of the MAGMA MIC library, an open source, high performance library that incorporates the developments presented here, and, more broadly, provid...

Diffusion Limited Aggregation (DLA) has usually been studied in 2 dimensions as a model of fractal growth processes such as branching, lightning, snowflakes, mineral deposits, and coral. Here, the basic principles are extended into 3 dimensions and used to create believable models of root systems. A straightforward approach is introduced for constraining the growth of the 3 dimensional DLA by a...

Digital loudspeaker arrays (DLAs) are electroacoustic transducers reconstructing acoustic signals out of binary audio streams, usually consisting of a digital signal processing module driving multiple actuators (small loudspeakers). In this work a DLA prototype was implemented using an all-digital audio chain driven by 1-bit sigma–delta signals. The prototype implementation is described and its...

A connection between fractal dimensions of ”turbulent facets”, and fractal dimensions in DLA is shown.

This article presents a selection analysis of the parameters used for a half-band filter in a digital Hilbert transformer. The parameters were determined for the transformer’s use in measuring Budeanu reactive power. This solution allowed to check the operation of the filter by comparing the results obtained with the filter with the results of Budeanu reactive power obtained in the frequency do...
