Efficient Multilingual Deep Learning Model for Keyword Categorization
No full textKeywords categorization is an essential tool for SEO (Search Engine Optimization), digital marketers, and online advertising. Keywords represent one of the most valuable pieces of information to infer the users' intents and interests. An effective keyword categorization method allows understanding what types of content are in the greatest demand and can help improve future content strategies or marketing/ad campaigns. In this paper, we present a novel deep learning model for multilingual keyword categorization. The model relies on fastText multilingual word embeddings, and its architecture is inspired by the DeepSets model. To make use of (training) words not included in the pre-trained fastText embeddings, we initialize them as the average embedding overall of the co-occurrent words. Then, we fine-tune these representations by allowing the network to back-propagate the error to the input. We assess the quality of our proposal on a real-world dataset provided by a Spanish company where keywords are categorized upon the Google Product Taxonomy (GPT). Empirical results show that our model can achieve high accuracy scores while being extremely efficient
Bromine-promoted glycosidation of conformationally superarmed thioglycosides
No full textPresented herein is our study of the conformation and reactivity of highly reactive thioglycoside donors. The structural studies have been conducted using NMR spectroscopic and computational methods. The reactivity of these donors has been investigated in bromine-promoted glycosylations of aliphatic and sugar alcohols. Swift reaction times, high yields, and respectable 1,2-cis stereoselectivity were observed in a majority of these glycosylations

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

No full textSimulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Structural, Superficial and Optical Properties of Nanostructured Polycrystalline ZnO:X (Cu, Ag) Films
No full textin root colonization and arbuscule formation
No full textThe colonization of Lotus japonicus roots by the arbuscular mycorrhizal fungus Glomus intraradices was analysed in plant mutants affected in the symbiosis genes, SYM15 or SYMRK. SYMRK encodes an LRR receptor-like kinase that is, like the SYM15 gene, essential for both mycorrhizal and rhizobial symbioses. Different colonization patterns were observed in growing vs meristematically arrested roots. Three steps in the interaction were differentially impaired in the mutants: surface opening, where the anticlinal cell walls of two adjacent epidermal cells separate from each other in the vicinity of fungal hyphae; intracellular passage of hyphae through an exodermal cell and an adjacent cell of the outermost cortical layer; and arbuscule formation in cells of the two innermost cortical layers. The combined results indicate that LjSYMRK is required for the intracellular passage through exodermis and outermost cortical cell layer whereas LjSYM15 is required for surface opening and arbuscule formation.
