The Willshaw model is asymptotically the most efficient neural associative memory (NAM), but its finite version is hampered by high retrieval errors. Iterative retrieval has been proposed in a large number of different models to improve performance in auto-association tasks. In this paper, bidirectional retrieval for the hetero-associative memory task is considered: we define information effici...

Near field acoustical signals from fireballs (ranges < 200 km), when detected by dense ground networks, may be used to estimate the orientation of trajectory a fireball (Pujol et al., 2005) as well fragmentation locations (Kalenda 2014; Edwards and Hildebrand, 2004). Distinguishing ballistic arrivals (from cylindrical shock fireball) generated (quasi-spherical sources) remains challenge, but ar...

abstract   earthquakes have been affected the human life since the dawn of time; however, the complexities of human societies and communications in the cities, intensify the deleterious effects of the earthquakes, that affect urban areas. hence, in emergency phase and reconstruction, attention to the basic needs and shelter provision are the most important activities but urban design also play ...

In normal individuals, the epithelium of the colon absorbs 1.5-2 l of water a day to generate dehydrated feces. However, in the condition of bile acid malabsorption (BAM), an excess of bile acids in the colon results in diarrhea. Several studies have attempted to address the mechanisms contributing to BAM induced by various bile acids. However, none have addressed a potential dysregulation of a...

Topographic mapping, e.g. the generation of Digital Elevation Models (DEM), is of general interest to the remote sensing community and scientific research. Commonly, photogrammetric methods, e.g. stereo image analysis methods (SIAM) or bundle adjustment methods (BAM), are applied to derive 3D information based on multiple images of an area. These methods require the detection of control points,...

In Gram-negative bacteria, the BAM (β-barrel assembly machinery) complex catalyzes the essential process of assembling outer membrane proteins. The BAM complex in Escherichia coli consists of five proteins: one β-barrel membrane protein, BamA, and four lipoproteins, BamB, BamC, BamD, and BamE. Despite their role in outer membrane protein biogenesis, there is currently a lack of functional and s...

The CLAVATA1 (CLV1) receptor kinase regulates stem cell specification at shoot and flower meristems of Arabidopsis. Most clv1 alleles are dominant negative, and clv1 null alleles are weak in phenotype, suggesting additional receptors functioning in parallel. We have identified two such parallel receptors, BAM1 and BAM2. We show that the weak nature of the phenotype of clv1 null alleles is depen...

We report on the performance of an end-to-end Bayesian analysis pipeline for detecting and characterizing galactic binary signals in simulated LISA data. Our principal analysis tool is the Blocked-Annealed Metropolis Hasting (BAM) algorithm, which has been optimized to search for tens of thousands of overlapping signals across the LISA band. The BAM algorithm employs Bayesian model selection to...

Stem cell biology covers a wide range of topics, as exemplified by the articles in this special review issue and the papers highlighted in this Stem Cell Select. Understanding the interactions of stem cells with their surroundings—whether they be Drosophila germ cells, human bone-forming precursors, or mouse immune modulators—will reveal important target mechanisms that can be exploited therape...

Business as Mission (BAM) is a subcategory of Social Entrepreneurship it seeks cultural innovation from Christian perspective focusing specifically on economic uplift and religious direction. Most BAM authors describe the kingdom God reign God. In theological review, I will show that defining simply God’s rule not complete view kingdom. Rather, more robust definition preferred in biblical studi...
