Passive Supporters of Terrorism and Phase Transitions

We discuss some social contagion processes to describe the formation and spread of radical opinions. The dynamics of opinion spread involves local threshold processes as well as mean field effects. We calculate and observe phase transitions in the dynamical variables resulting in a rapidly increasing number of passive supporters. This strongly indicates that military solutions are inappropriate.Comment: references added concerning previous work of S. Gala

Fitting the need

A compendium of advice from the National Board of Employment, Education and Training to the federal government in 1992 in regards to the appropriate balance of growth between the education and training sectors. It provides a holistic look of the trends in education and training systems in Australia in the early 1990s, and the recommendations presented to the Department of Employment, Education and Training

Simultaneous identification of long similar substrings in large sets of sequences

<p>Abstract</p> <p>Background</p> <p>Sequence comparison faces new challenges today, with many complete genomes and large libraries of transcripts known. Gene annotation pipelines match these sequences in order to identify genes and their alternative splice forms. However, the software currently available cannot simultaneously compare sets of sequences as large as necessary especially if errors must be considered.</p> <p>Results</p> <p>We therefore present a new algorithm for the identification of almost perfectly matching substrings in very large sets of sequences. Its implementation, called ClustDB, is considerably faster and can handle 16 times more data than VMATCH, the most memory efficient exact program known today. ClustDB simultaneously generates large sets of exactly matching substrings of a given minimum length as seeds for a novel method of match extension with errors. It generates alignments of maximum length with a considered maximum number of errors within each overlapping window of a given size. Such alignments are not optimal in the usual sense but faster to calculate and often more appropriate than traditional alignments for genomic sequence comparisons, EST and full-length cDNA matching, and genomic sequence assembly. The method is used to check the overlaps and to reveal possible assembly errors for 1377 <it>Medicago truncatula </it>BAC-size sequences published at <url>http://www.medicago.org/genome/assembly_table.php?chr=1</url>.</p> <p>Conclusion</p> <p>The program ClustDB proves that window alignment is an efficient way to find long sequence sections of homogenous alignment quality, as expected in case of random errors, and to detect systematic errors resulting from sequence contaminations. Such inserts are systematically overlooked in long alignments controlled by only tuning penalties for mismatches and gaps.</p> <p>ClustDB is freely available for academic use.</p

Superconducting tunnel junction array development for high-resolution energy-dispersive x-ray spectroscopy

Cryogenic energy-dispersive x-ray detectors are being developed because of their superior energy resolution ((less than or equal to) 10 eV FWHM for keV x rays) compared to semiconductor EDS systems. So far, their range of application is limited due to their comparably small size and low count rate. We present data on the development of superconducting tunnel junction (STJ) detector arrays to address both of these issues. A single STJ detector has a resolution around 10 eV below 1 keV and can be operated at count rates of order 10,000 counts/s. We show that the simultaneous operation of several STJ detectors does not diminish their energy resolution significantly, while increasing the detector area and the maximum count rate by a factor given by the total number of independent channels

Building in Quatar - Field excursion of the Faculty of Civil Engineering of the HTWG Konstanz

Die große Exkursion 2010 der Fakultät Bauingenieurwesen führte in das Emirat Qatar am persischen Golf. Qatar verfügt über 15% der weltweiten Reserven anErdgas und investiert u.a. in Infrastruktur- und Bau¬maßnahmen. Deutsche Firmen sind an diesem Aufbau beteiligt. Bei der Exkursion wurden verschiedene Hoch- und Tiefbaustellen, „Mega-Projekte“ deutscher Unternehmen, aber auch eines arabischen Baukonzerns besucht. Auch das Ausstellungszentrum der Deutschen Bahn stand auf dem Programm. Der Bericht gibt die Eindrücke beim Besuch der Projekte wie auch die Reiseerlebnisse wieder.The student excursion of the University of Applied Sciences, Konstanz, Germany, lead to the Emirat of Qatar at the Persian Gulf. The country possesses 15% of the reserves of natural gas and is investing in building and infrastructures measures. German companies are part of this development. During the excursion different structural sites of “mega-projects” of German and Arabic Companies as well as the exposition Center of the “Deutsche Bahn” have been visited
