We have devized a methodology that mines sequential navigation patterns from a website's logs to enable us to identify the most signi cant associative links in the networks. Spreading activation can then be applied to the generated network of weighted hyperlinks enabling the content-dependent, semantic retrieval of nodes in the network. This approach to information retrieval avoids many of the ...

Motivated by the properties of spreading activation and conceptual distance, the authors propose a metric, called Distance, on the power set of nodes in a semantic net. Distance is the average minimum path length over all painvise combinations of nodes between two subsets of nodes. Distance can be successfully used to assess the conceptual distance between sets of concepts when used on a semant...

Trench-fin MOSFETs, with their near-surface heat generation and the higher-surface area afforded by geometry for thermal management, represent a promising solution to problems frequently encountered in lateral β-Ga2O3 devices. Here, we investigate potential thermal-management strategies vertical trench-fin MOSFET through parametric analysis, offering recommendations on how best design device ma...

As numerous bacterial species, Shewanella putrefaciens CN-32 possesses a complete secondary flagellar system. A significant subpopulation of CN-32 cells induces expression of the secondary system under planktonic conditions, resulting in formation of one, sometimes two, filaments at lateral positions in addition to the primary polar flagellum. Mutant analysis revealed that the single chemotaxis...

We have studied the capillary spreading of a Newtonian liquid along hydrophilic microstripes that are chemically defined on a hydrophobic substrate. The front of the spreading film advances in time according to a power law x=Bt(1/2). This exponent of 1/2 is much larger than the value 1/10 observed in the axisymmetric spreading of a wetting droplet. It is identical to the exponent found for wick...

The fusion and spreading of phospholipid bilayers on glass surfaces was investigated as a function of pH and ionic strength. Membrane fusion to the support was favorable at high ionic strength and low pH for vesicles containing a net negative charge; however, neutral and positively charged vesicles fused under all conditions attempted. This result suggests that van der Waals and electrostatic i...

The soil-pile kinematic interaction under large nonlinearity, including soil liquefaction, represents a complex phenomenon that depends on many unforeseen factors. This paper presents the results of dynamic centrifuge tests carried out considering varying sloping inclination angles for liquefiable ground subjected to four successive earthquake shakings having an increasing amplitude acceleratio...
