Universal router concept

Portable universal router can cut holes of large diameter and irregular shapes, machine recesses, and drill holes with certain edge-distance limitations. Rectangular and round holes may be cut without a template

Variable-speed, portable routing skate

Lightweight, portable, variable-speed routing skate is used on heavy metal subassemblies which are impractical to move to a stationary machine. The assembly, consisting of the housing with rollers, router, and driving mechanism with transmission, weighs about forty pounds. Both speed and depth of cut are adjustable

Weakly Nonlinear Theory of Pattern-Forming Systems with Spontaneously Broken Isotropy

Quasi two-dimensional pattern forming systems with spontaneously broken isotropy represent a novel symmetry class, that is experimentally accessible in electroconvection of homeotropically aligned liquid crystals. We present a weakly nonlinear analysis leading to amplitude equations which couple the short-wavelength patterning mode with the Goldstone mode resulting from the broken isotropy. The new coefficients in these equations are calculated from the hydrodynamics. Simulations exhibit a new type of spatio-temporal chaos at onset. The results are compared with experiments.Comment: 4 pages, RevTeX, 4 PS-figures, to appear in PR

PLANNING AND FACILITATING TRAINING PROGRAMS WITH MULTICULTURAL GROUPS

Demographic changes in the work environments present numerous challenges for training professionals interested in fostering awareness and sensitivity to cultural diversity when planning and facilitating adult education programs. As a professional trainer who works with multicultural groups in urban settings, I am exploring ways in which race, ethnicity, gender and age influence planning and facilitating training programs. In this paper I am addressing the social construction of race, ethnicity, gender and age and how training professionals might deal with the influence of these concepts in curriculum planning and facilitating training programs

Entropy Change through Rayleigh-B\'enard Convective Transition with Rigid Boundaries

The previous investigation on Rayleigh-B\'enard convection of a dilute classical gas [T. Kita: J. Phys. Soc. Jpn. {\bf 75} (2006) 124005] is extended to calculate entropy change of the convective transition with the rigid boundaries. We obtain results qualitatively similar to those of the stress-free boundaries. Above the critical Rayleigh number, the roll convection is realized among possible steady states with periodic structures, carrying the highest entropy as a function of macroscopic mechanical variables.Comment: 5 pages, 4 figure

ConReg: Analysis and Visualization of Conserved Regulatory Networks in Eukaryotes

Transcription factors (TFs) play a fundamental role in cellular regulation by binding to promoter regions of target genes (TGs) in order to control their gene expression. TF-TG networks are widely used as representations of regulatory mechanisms, e.g. for modeling the cellular response to input signals and perturbations. As the experimental identification of regulatory interactions is time consuming and expensive, one tries to use knowledge from related species when studying an organism of interest. Here, we present ConReg, an interactive web application to store regulatory relations for various species and to investigate their level of conservation in related species. Currently, ConReg contains data for eight model organisms. The regulatory relations stored in publicly available databases cover only a small fraction both of the actual interactions and also of the regulatory relations described in the scientific literature. Therefore, we included regulatory relations extracted from PubMed and PubMedCentral using sophisticated text-mining approaches and from binding site predictions into ConReg. We applied ConReg for the investigation of conserved regulatory motifs in D. melanogaster. From the 471 regulatory relations in REDfly our system was able to identify 66 confirmed conserved regulations in at least one vertebrate model organism (H. sapiens, M. musculus, R. norvegicus, D. rerio). The conserved network consists among others of the well studied motifs for eye-development and the pan-bilaterian kernel for heart specification, which are well-known examples for conserved regulatory relations between different organisms. ConReg is available at http://services.bio.ifi.lmu.de/ConReg/ and can be used to analyze and visualize regulatory networks and their conservation among eight model organisms. It also provides direct links to annotations including literature references to potentially conserved regulatory relations
