Release From Cross-Orientation Suppression Facilitates 3d Shape Perception, Andrea Li, Qasim Zaidi

Publications and Research

Cross-orientation suppression (COS) in striate cortex has been implicated in the efficient encoding of visual stimuli. We show that release from COS facilitates the decoding of 3-D shape. In planar surfaces overlaid with textures, slanting the surface can increase the visibility of the component parallel to the slant. Since this component provides the orientation flows that signify 3-D shape, the enhancement of visibility facilitates 3-D slant perception. Contrast thresholds reveal that this enhancement results from a decrease in COS when 3-D slant creates a frequency mismatch between texture components. We show that coupling compressive nonlinearities in LGN neurons with expansive …

Optimal Cryptographic Hardness Of Learning Monotone Functions, Dana Dachman-Soled, Homin K. Lee, Tal Malkin, Rocco A. Servedio, Andrew Wan, Hoeteck Wee

Publications and Research

Over the years a range of positive algorithmic results have been obtained for learning various classes of monotone Boolean functions from uniformly distributed random examples. Prior to our work, however, the only negative result for learning monotone functions in this model has been an information-theoretic lower bound showing that certain super-polynomial-size monotone circuits cannot be learned to accuracy 1/2+w(log n/ p n) (Blum, Burch, and Langford, FOCS’98). This is in contrast with the situation for nonmonotone functions, where a wide range of cryptographic hardness results establish that various “simple” classes of polynomial-size circuits are not learnable by polynomial-time algorithms.

Sustained Release Of Multiple Growth Factors From Injectable Polymeric System As A Novel Therapeutic Approach Towards Angiogenesis, Qinghua Sun, Eduardo A. Silva, Aixia Wang, James C. Fritton, David J. Mooney, Mitchell B. Schaffler, Paul M. Grossman, Sanjay Rajagopalan

Publications and Research

Purpose The aim was to investigate that a bio-degradable alginate and poly lactide-co-glycolide (PLG) system capable of delivering growth factors sequentially would be superior to single growth factor delivery in promoting neovascularization and improving perfusion. Methods Three groups of apoE null mice underwent unilateral hindlimb ischemia surgery and received ischemic limb intramuscular injections of alginate (Blank), alginate containing VEGF165 (VEGF), or alginate containing VEGF165 combined with PLG microspheres containing PDGF-BB (VEGF/PDGF). Vascularity in the ischemic hindlimb was assessed by morphologic and immunohistochemical end-points, while changes in blood flow were assessed by Laser Doppler Perfusion Index. Muscle VEGF and PDGF content …

Linkage Among U.S. Interest Rates And East Asian Purchases Of U.S. Treasury Securities, Dene T. Hurley Dr.

Publications and Research

Recent increases in East Asian purchases of US treasury securities has led to growing concern over its impact on the US economy, particularly on the US long-term and shortterm interest rates. The vector error-correction model results revealed the presence of long-run causal relations among the federal funds rate, the 10-year Treasury rate and the East Asian demand in addition to a unidirectional short-run causal relation from the 10-year rate to the Federal funds rate. The variance decomposition and impulse response findings indicated that the Asian demand for US assets has a limited but negative impact on the 10-year US Treasury …

Nonknowledge: The Bibliographical Organization Of Ignorance, Stupidity, Error, And Unreason: Part Two, Jay H. Bernstein

Publications and Research

Starting with the Data-Information-Knowledge-Wisdom paradigm in information science it is possible to derive a model of the opposite of knowledge having hierarchical qualities. A range of counterpoints to concepts in the knowledge hierarchy can be identified and ascribed the overall term “nonknowledge.” This model creates a conceptual framework for understanding the connections between topics such as error, ignorance, stupidity, folly, popular misconceptions, and unreason by locating them as levels or phases of nonknowledge. The concept of nonknowledge links heretofore disconnected discourses on these individual topics by philosophers, psychologists, historians, sociologists, satirists, and others. Subject headings provide access to the categories …

Egg Eviction Imposes A Recoverable Cost Of Virulence In Chicks Of A Brood Parasite, Michael G. Anderson, Csaba Moskát, Miklós Bán, Tomáš Grim, Phillip Cassey, Mark E. Hauber

Publications and Research

Background Chicks of virulent brood parasitic birds eliminate their nestmates and avoid costly competition for foster parental care. Yet, efforts to evict nest contents by the blind and naked common cuckoo Cuculus canorus hatchling are counterintuitive as both adult parasites and large older cuckoo chicks appear to be better suited to tossing the eggs and young of the foster parents. Methodology/Principal Findings Here we show experimentally that egg tossing imposed a recoverable growth cost of mass gain in common cuckoo chicks during the nestling period in nests of great reed warbler Acrocephalus arundinaceus hosts. Growth rates of skeletal traits and …

Pointcut Rejuvenation: Recovering Pointcut Expressions In Evolving Aspect-Oriented Software, Raffi Khatchadourian, Phil Greenwood, Awais Rashid, Guoqing Harry Xu

Publications and Research

Pointcut fragility is a well-documented problem in Aspect-Oriented Programming; changes to the base-code can lead to join points incorrectly falling in or out of the scope of pointcuts. We present an automated approach that limits fragility problems by providing mechanical assistance in pointcut maintenance. The approach is based on harnessing arbitrarily deep structural commonalities between program elements corresponding to join points selected by a pointcut. The extracted patterns are then applied to later versions to offer suggestions of new join points that may require inclusion. We demonstrate the usefulness of our technique by rejuvenating pointcuts in multiple versions of several …

Manipulating Neuronal Circuits With Endogenous And Recombinant Cell-Surface Tethered Modulators, Mande Holford, Sebastian Auer, Martin Laqua, Ines Ibanez-Tallon

Publications and Research

Neuronal circuits depend on the precise regulation of cell-surface receptors and ion channels. An ongoing challenge in neuroscience research is deciphering the functional contribution of specifi c receptors and ion channels using engineered modulators. A novel strategy, termed “tethered toxins”, was recently developed to characterize neuronal circuits using the evolutionary derived selectivity of venom peptide toxins and endogenous peptide ligands, such as lynx1 prototoxins. Herein, the discovery and engineering of cell-surface tethered peptides is reviewed, with particular attention given to their cell-autonomy, modular composition, and genetic targeting in different model organisms. The relative ease with which tethered peptides can be …

Mercury Exposure, Nutritional Deficiencies And Metabolic Disruptions May Affect Learning In Children, Renee Dufault, Roseanne Schnoll, Walter J. Lukiw, Blaise Leblanc, Charles Cornett, Lyn Patrick, David Wallinga, Steven G. Gilbert, Raquel Crider

Publications and Research

Among dietary factors, learning and behavior are influenced not only by nutrients, but also by exposure to toxic food contaminants such as mercury that can disrupt metabolic processes and alter neuronal plasticity. Neurons lacking in plasticity are a factor in neurodevelopmental disorders such as autism and mental retardation. Essential nutrients help maintain normal neuronal plasticity. Nutritional deficiencies, including deficiencies in the long chain polyunsaturated fatty acids eicosapentaenoic acid and docosahexaenoic acid, the amino acid methionine, and the trace minerals zinc and selenium, have been shown to influence neuronal function and produce defects in neuronal plasticity, as well as impact behavior …

Cooperative Social Clusters Are Not Destroyed By Dispersal In A Ciliate, Nicolas Schtickzelle, Else J. Fjerdingstad, Alexis Chaine, Jean Clobert

Publications and Research

Background The evolution of social cooperation is favored by aggregative behavior to facilitate stable social structure and proximity among kin. High dispersal rates reduce group stability and kin cohesion, so it is generally assumed that there is a fundamental trade-off between cooperation and dispersal. However, empirical tests of this relationship are rare. We tested this assumption experimentally using ten genetically isolated strains of a ciliate, Tetrahymena thermophila. Results The propensity for social aggregation was greater in strains with reduced cell quality and lower growth performance. While we found a trade-off between costly aggregation and local dispersal in phenotypic analyses, aggregative …

Harnessing Gene Expression To Identify The Genetic Basis Of Drug Resistance, Bo-Juen Chen, Helen C. Causton, Denesy Mancenido, Noel L. Goddard, Ethan O. Perlstein, Dana Pe'er

Publications and Research

The advent of cost-effective genotyping and sequencing methods have recently made it possible to ask questions that address the genetic basis of phenotypic diversity and how natural variants interact with the environment. We developed Camelot (CAusal Modelling with Expression Linkage for cOmplex Traits), a statistical method that integrates genotype, gene expression and phenotype data to automatically build models that both predict complex quantitative phenotypes and identify genes that actively influence these traits. Camelot integrates genotype and gene expression data, both generated under a reference condition, to predict the response to entirely different conditions. We systematically applied our algorithm to data …

Contributing Factors To Pointcut Fragility, Phil Greenwood, Awais Rashid, Raffi Khatchadourian

Publications and Research

Pointcut fragility is a well-documented problem of Aspect-Oriented Programming with changes to the base-code causing join points to incorrectly fall in or out of scope. In order to combat this problem a tool was developed that provides mechanical assistance to pointcut maintenance. This tool relied on the deep structural commonalities between program elements to detect when pointcut fragility occurs. During the assessment of this tool a number of common practices were uncovered that were employed both in the aspect and base-code that contributed to or prevented pointcut fragility. This paper documents the practices uncovered and describes how they can affect …

Ron’S Right Arm: Tactility, Visualization, And The Synesthesia Of Audio Engineering, Eliot Bates

Publications and Research

Most scholarship on audio engineering analyzes practices and practitioners in terms of musical and technical knowledges. The few references to sensory perception typically center on critical listening practices (“golden ears” engineers), audiophilia, and technologies of audition. However, particularly in light of computer-based workflows, the practice of audio engineering features carefully developed synesthesias of critical listening, visualization of digital audio, and tactile manipulations of interfaces, which can’t adequately be explained as cognitive processes or as conscious knowledge.

I draw on literature in the emerging field of sensory scholarship, in particular Brian Massumi’s theorization of synesthesia and affect and Charles Hirschkind’s analyses …
