Abstract: The global exponential stability is investigated for a class of reaction-diffusion Cohen-Grossberg-type BAM neural networks with time delays. By constructing suitable Lyapunov functional and using homeomorphism mapping, several sufficient conditions guaranteeing the existence, uniqueness and global exponential stability of reaction-diffusion Cohen-Grossberg-type BAM neural networks wi...

In this paper, we discuss parallel implementation of an artificial neural network for pattern d a t i o n , the Bidirectional Associative Memory(BAM). Transputer-based parallel architecture8 like hypercube, mesh and linear array are used to exploit the parallelism in BAM. A comparitive study of utilization and speedup for various architectures is made. Hypercube performs better in terms of util...

In this paper,the exponential passivity criteria for BAM neural networks with time-varying delays is studied.By constructing new Lyapunov-Krasovskii functional and dividing the delay interval into multiple segments,a novel sufficient condition is established to guarantee the exponential stability of the considered system.Finally,a numerical example is provided to illustrate the usefulness of th...

⎯By employing the Lyapunov stability theory and linear matrix inequality (LMI) technique, delaydependent stability criterion is derived to ensure the exponential stability of bi-directional associative memory (BAM) neural networks with time-varying delays. The proposed condition can be checked easily by LMI control toolbox in Matlab. A numerical example is given to demonstrate the effectiveness...

Rats given high doses of colchicine (300-400 ug, i.c.v.) were used to investigate the comparative distribution of Leu-enkephalin and bovine adrenal medullary enkephalinprecursor fragment (BAM-22P) in the brain. Leu-enkephalin immunoreactive neurons have a widespread distribution throughout the neuraxis. In most areas adjacent section analysis showed BAM-22P and Leu-enkephalin immunoreactive per...

MOTIVATION The reference CRAM file format implementation is in Java. We present 'Scramble': a new C implementation of SAM, BAM and CRAM file I/O. RESULTS The C implementation of for CRAM is 1.5-1.7× slower than BAM at decoding but 1.8-2.6× faster at encoding. We see file size savings of 34-55%. AVAILABILITY AND IMPLEMENTATION Source code is available at http://sourceforge.net/projects/stade...

Outer membrane proteins (OMPs) play a central role in the integrity of the outer membrane of Gram-negative bacteria. Unfolded OMPs (uOMPs) transit across the periplasm, and subsequent folding and assembly are crucial for biogenesis. Chaperones and the essential β-barrel assembly machinery (BAM) complex facilitate these processes. In vitro studies suggest that some chaperones sequester uOMPs in ...

In the Drosophila ovary, germline stem cells (GSCs) are maintained primarily by bone morphogenetic protein (BMP) ligands produced by the stromal cells of the niche. This signaling represses GSC differentiation by blocking the transcription of the differentiation factor Bam. Remarkably, bam transcription begins only one cell diameter away from the GSC in the daughter cystoblasts (CBs). How this ...

Introduction: Tooth extraction can result in loss of alveolar bone. The application biomaterials Bovine Amniotic Membrane (BAM) that containing growth factors and collagen is expected to play a role socket preservation. This study aimed observe the effect BAM on osteoblasts, osteocytes, histological preparate bone Sprague Dawley rats (SD). Methods: 16 male SD were used this group. extracted man...
