We show that a new expansion which sums seagull and bubble graphs to all orders, can be applied to the O(N)-linear σ-model at finite temperature. We prove that this expansion can be renormalised with the usual counterterms in a mass independent scheme and that Goldstone’s theorem is satisfied at each order. At the one loop order of this expansion, the Hartree result for the effective potential ...
We investigate the manual and automatic annotation of PDTB discourse relations in student essays, a novel domain that is not only learning-based and argumentative, but also noisy with surface errors and deeper coherency issues. We discuss methodological complexities it poses for the task. We present descriptive statistics and compare relation distributions in related corpora. We compare automat...
Studies of discourse relations have not, in the past, attempted to characterize what serves as evidence for them, beyond lists of frozen expressions, or markers, drawn from a few well-defined syntactic classes. In this paper, we describe how the lexicalized discourse relation annotations of the Penn Discourse Treebank (PDTB) led to the discovery of a wide range of additional expressions, annota...
The current study presents a conversion and unification of the Penn Discourse TreeBank 2.0 under the XML format. The converted corpus allows for a simultaneous search for syntactically specified discourse information on the basis of the
The Presidential Election in Mexico of July 2012 has been the third time that PREP, Previous Electoral Results Program works. PREP gives voting outcomes based in electoral certificates of each polling station that arrive to capture centers. In previous ones, some statistical regularities had been observed, three of them were selected to make predictions and were published in arXiv:1207.0078 [ph...
A glutathione S-transferase-like gene, DcGSTF2, is responsible for carnation (Dianthus caryophyllus L.) flower color intensity. Two defective genes, DcGSTF2mu with a nonsense mutation and DcGSTF2-dTac1 containing a transposable element dTac1, have been characterized in detail in this report. dTac1 is an active element that produces reverted functional genes by excision of the element. A pale-pi...
Systems with redundant control actuators are sometimes arranged so that a new actuator comes into play if the one normally used becomes saturated. We call this ‘daisy-chaining’. Such an arrangement also provides a degree of faulttolerance against actuator failures. This paper points out that a similar property is implicit in constrained predictive control, as it is usually formulated. Predictiv...
We describe preliminary work on applying the Penn Discourse Treebank framework (PDTB, Prasad et al., 2008) and the Cognitive approach to Coherence Relations (CCR, Sanders, Spooren & Noordman, 1992) to spoken language. Due to register differences, we do not only expect to see a distribution of discourse relations that deviates from the one in written text, but also expect to come across new rela...
How the two killer proteins Bax and Bak form the putative “apoptotic pore” that is responsible for irrevocably damaging mitochondria leading to cell death during apoptosis is considered the “holy grail” of apoptosis research. Indeed, even whether Bax and Bak form a pore remains contentious largely due to the failure to detect such structures in cells or mitochondria. Two new super-resolution mi...
