Differential gene expression during compensatory sprouting of dendrites in the auditory system of the cricket Gryllus bimaculatus

- Neurones that lose their presynaptic partners because of injury usually retract or die. However, when the auditory interneurones of the cricket Gryllus bimaculatus are denervated, dendrites respond by growing across the midline and forming novel synapses with the opposite auditory afferents. Suppression subtractive hybridization was used to detect transcriptional changes 3 days after denervation. This is a stage at which we demonstrate robust compensatory dendritic sprouting. Whereas 49 unique candidates were down-regulated, no sufficiently up-regulated candidates were identified at this time point. Several candidates identified in this study are known to influence the translation and degradation of proteins in other systems. The potential role of these factors in the compensatory sprouting of cricket auditory interneurones in response to denervation is discussed. © 2009 The Royal Entomological Society.
DC-SSAT: A divide-and-conquer approach to solving stochastic satisfiability problems efficiently
Date: 2005-12-01
Creator: Stephen M. Majercik, Byron Boots
Access: Open access
- We present DC-SSAT, a sound and complete divide-and-conquer algorithm for solving stochastic satisfiability (SSAT) problems that outperforms the best existing algorithm for solving such problems (ZANDER) by several orders of magnitude with respect to both time and space. DC-SSAT achieves this performance by dividing the SSAT problem into subproblems based on the structure of the original instance, caching the viable partial assignments (VPAs) generated by solving these subproblems, and using these VPAs to construct the solution to the original problem. DC-SSAT does not save redundant VPAs and each VPA saved is necessary to construct the solution. Furthermore, DC-SSAT builds a solution that is already human-comprehensible, allowing it to avoid the costly solution rebuilding phase in ZANDER. As a result, DC-SSAT is able to solve problems using, typically, 1-2 orders of magnitude less space than ZANDER, allowing DC-SSAT to solve problems ZANDER cannot solve due to space constraints. And, in spite of its more parsimonious use of space, DC-SSAT is typically 1-2 orders of magnitude faster than ZANDER. We describe the DC-SSAT algorithm and present empirical results comparing its performance to that of ZANDER on a set of SSAT problems.

Promoting the "Public Welfare" in Wartime: Stanford University during World War II
Date: 2005-11-01
Creator: Charles Dorn
Access: Open access
- As with many U.S. colleges and universities during World War II, Stanford University responded to the demands of mobilization by increasing its commitment to technical training and adopting a defense research agenda. In a striking departure from this national trend, however, Stanford also established its School of Humanities in 1942. By examining such seemingly disparate pursuits, this study reveals the complexity of the challenges that confronted institutions of higher education throughout the war era. Stanford University's simultaneous embrace of these programs illuminates broad concerns regarding the role of higher education in fostering civic-mindedness in a society denned by rapid technological advance and the perception of an ever-increasing threat to national security. © 2005 by The University of Chicago.
