Bidirectional Associative Memories (BAMs) are artificial neural networks that can learn and recall various types of associations. Although BAMs have shown great promise at modeling human cognitive processes, these models have often been investigated under optimal conditions in which the network is fully connected. Whereas some BAM models have shown to be robust to connection sparseness, those p...

In this article, issues of both stability and dissipativity for a type bidirectional associative memory (BAM) neural systems with time delays are investigated. By using generalized Halanay inequalities constructing appropriate Lyapunov functionals, some novelty criteria obtained the asymptotic BAM delays. Also, without assuming boundedness differentiability activation functions, new sufficient ...

Bam-readcount is a utility for generating low-level information about sequencing data at specific nucleotide positions. Originally designed to help filter genomic mutation calls, the metrics it outputs are useful as input variant detection tools and resolving ambiguity between callers . In addition, has found broad applicability in diverse fields including tumor evolution, single-cell genomics,...

Cyclins regulate progression through the cell cycle. Control of cyclin levels is essential in Drosophila oogenesis for the four synchronous divisions that generate the 16 cell germ line cyst and for ensuring that one cell in each cyst, the oocyte, is arrested in meiosis, while the remaining fifteen cells become polyploid nurse cells. Changes in cyclin levels could be achieved by regulating tran...

UNLABELLED Many if not most proteins function in oligomeric assemblies of one or more protein sequences. The Protein Data Bank provides coordinates for biological assemblies for each entry, at least 60% of which are dimers or larger assemblies. BioAssemblyModeler (BAM) is a graphical user interface to the basic steps in homology modeling of protein homooligomers and heterooligomers from the bio...

Microarray hybridization or antibody binding can be detected by many techniques, however, only a few are suitable for widespread use since many of these detection techniques rely on bulky and expensive instruments. Here, we describe the usefulness of a simple and inexpensive detection method based on gold nanoparticle labeled antibodies visualized by a commercial, office desktop flatbed scanner...

Stem cells in adult tissues share two defining characteristics – cell division is self-renewing and asymmetric. In the Drosophila oogenic germline, the self-renewing aspect of the division produces a new stem cell that remains associated with a complement of somatic cells (terminal filament cells, cap cells and inner sheath cells; collectively, somatic tip cells) that maintain a supportive micr...

Bidirectionality, forward and backward information flow, is introduced in neural networks to produce two-way associative search for stored stimulus-response associations (A(i),B(i)). Two fields of neurons, F(A) and F(B), are connected by an n x p synaptic marix M. Passing information through M gives one direction, passing information through its transpose M(T) gives the other. Every matrix is b...

Stress-activated gene × environment interactions may contribute to individual variability in blood pressure reductions from behavioral interventions. We investigated effects of endothelin-1 (ET-1) LYS198ASN SNP and discriminatory stress exposure upon impact of 12-week behavioral interventions upon ambulatory BP (ABP) among 162 prehypertensive African American adolescents. Following genotyping, ...
