  • The handbook is written for mature readers with a great deal of rigorous experience with either doing scientific research or writing scientific software. However no specific background in computer science, statistics, or biology is required to understand most of the chapters. In order to accommodate the readers who wish to become professional computational biologists in the future we also provide appendices that contain educationally sound glossaries of terms and descriptions of major sequence analysis algorithms.

  • More recently, Cox and Fisher (2009) analyzed the titles of contemporary romance novels to determine if their popularity might be related to evolutionary themes that would be expected to have widespread appeal when it comes to some of the unique and recurrent reproductive issues that women confront. The five most common words featured in romance novel titles were love, bride, baby, man, and marriage, in that order. Common themes extracted from these titles included commitment, reproduction, masculine/high ranking suitors, and resources.

  • Reliable and cost-effective monitoring will be an important part of making GS a safe, effective, and acceptable method for CO2 control. Monitoring will be required as part of the permitting process for underground injection and will be used for a number of purposes, such as tracking the location of the plume of injected CO2, ensuring that injection and abandoned wells are not leaking, and verifying the quantity of CO2 that has been injected underground.

  • Nested event structures are a common occurrence in both open domain and domain specific extraction tasks, e.g., a “crime” event can cause a “investigation” event, which can lead to an “arrest” event. However, most current approaches address event extraction with highly local models that extract each event and argument independently.

  • The assessment identifies the strengths in the health system of Uganda and also the challenges that the Ministry of Health, with development partners, the private sector, and civil society, will need to address. System strengths include the participatory nature of health sector governance, the use of evidence generated locally and internationally to inform policy-making, improved collaboration between government and development partners, and the increase in the number of potential service delivery points across the country.

  • We apply the hypothesis of “One Sense Per Discourse” (Yarowsky, 1995) to information extraction (IE), and extend the scope of “discourse” from one single document to a cluster of topically-related documents. We employ a similar approach to propagate consistent event arguments across sentences and documents. Combining global evidence from related documents with local decisions, we design a simple scheme to conduct cross-document inference for improving the ACE event extraction task 1 . ...

  • In this paper, we exploit non-local features as an estimate of long-distance dependencies to improve performance on the statistical spoken language understanding (SLU) problem. The statistical natural language parsers trained on text perform unreliably to encode non-local information on spoken language. An alternative method we propose is to use trigger pairs that are automatically extracted by a feature induction algorithm. We describe a light version of the inducer in which a simple modification is efficient and successful. ...

  • We propose an approach for extracting relations between entities from biomedical literature based solely on shallow linguistic information. We use a combination of kernel functions to integrate two different information sources: (i) the whole sentence where the relation appears, and (ii) the local contexts around the interacting entities. We performed experiments on extracting gene and protein interactions from two different data sets. The results show that our approach outperforms most of the previous methods based on syntactic and semantic information. ...

  • Antibiotic agents have been in widespread and largely effective therapeutic use since their discovery in the 20th century. However, the emergence of multi-drug resistant pathogens now presents an increasing global challenge to both human and veterinary medicine. It is now widely acknowledged that there is a need to develop novel antimicrobial agents to minimize the threat of further antimicrobial resistance.

  • After the ore is extracted, it is generally transferred by bridge conveyor, shuttle cars or load-haul-dump units to a system of conveyors that carry it to underground storage bins, prior to haulage to the surface through a shaft by automated skips. On rare occasions shallow mines may use a decline and conveyor arrangement. Solution mining is currently used at a number of operations in North America. The process relies on the greater solubility at elevated temperatures in brine of sylvite in comparison to salt (NaCl).

  • Continuous-time modeling in finance, though introduced by Louis Bachelier's 1900 thesis on the theory of speculation, really started with Merton's seminal work in the 1970s. Since then, the continuous-time paradigm has proved to be an immensely useful tool in finance and more generally economics. Continuous-time models are widely used to study issues that include the decision to optimally consume, save, and invest, portfolio choice under a variety of constraints, contingent claim pricing, capital accumulation, resource extraction, game theory, and more recently contract theory....

  • There has been much previous work on node localization and event detection [6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16] , includ- ing foundational work on theoretical lower bounds [17, 18]. Sex- tant differentiates itself from this body of work in several ways. First, it does not assume uniform transmission radii (i.e.

  • Typically the processes are adapted from wood processing which benefit from the larger mill size (Paper I). However, concerns associated with the local availability of non-wood raw material force pulp mills to remain small and thus lead to the need for processes to be as simple as possible in order to be competitive unless very valuable by-products can also be extracted. The benefits of utilising agro-fibres are their generally lower lignin content compared with woods (Grant 1958, Hurter 1988).

  • According to ASTM Standard Guide nondestructive term Test, the sound emission is usually defined as the class of phenomena whereby transient elastic waves generated by the rapid release of energy from source localization in the material. Energy consumption is essentially due to phase converter, crack formation and development, friction or movement of dislocations. Acoustic emission signal can be generated by phenomena such as cavitation, leakage, solidification and liquefaction.

  • Event recognition methods can be roughly categorized into model-based methods and appearance-based techniques. Model-based approaches relied on various models, includ- ing HMM [35], coupled HMM [3], and Dynamic Bayesian Network [33], to model the temporal evolution. The relationships among different body parts and regions are also modeled in [3], [35], in which object tracking needs to be conducted at first before model learning.

  • The booklet describes the safe method of using level crossings, including the need to obey the instructions on the signs and the requirement to always to close the gates after crossing. It also sets out the hazards associated with various types of vehicles, pedestrians and cyclists using the level crossing and the local conditions such as adverse weather or overgrown vegetation which might affect the safety of the user. Illustrated below are some of the extracts from the booklet, which are relevant to this accident. ...

  • The rest of the paper is structured as follows. The next section discusses related work and expands on Sextant’s contributions. In sections 3 through 6, we discuss the basic operation of Sextant, including its area representation, its extraction of constraints from wireless radios and sensors, and its distributed solution techniques for node and event localization. Section 7 describes how the inter- action between node and event localization can be used to refine position estimates. Section 8 describes the network protocol used to obtain and combine position estimates.

  • Riftia pachyptila(Vestimentifera) is a giant tubeworm living around the volcanic deep-sea vents of the East Pacific Rise. This animal is devoid of a digestive tract and lives in an intimate symbiosis with a sulfur-oxidizing chemoauto-trophic bacterium. This bacterial endosymbiont is localized in the cells of a richly vascularized organ of the worm: the trophosome.
