In 1991, David Gale and Raphael Robinson, building on explorations carried out by Michael Somos in the 1980s, introduced a three-parameter family of rational recurrence relations, each of which (with suitable initial conditions) appeared to give rise to a sequence of integers, even though a priori the recurrence might produce non-integral rational numbers. Throughout the '90s, proofs of integrality were known only for individual special cases. In the early '00s, Sergey Fomin and Andrei Zelevinsky proved Gale and Robinson's integrality conjecture.
17 page Christmas short story set in Cuba. Three boys play the Three Kings who deliver gifts on the eve of Epiphany. But what will they give the poor children they pass on the street? A delightful story of strong tradition broken by the power of…
Young children acquire language naturally. Unlike the adults, the children receive language without realizing that they are learning the language. They have the ability to imitate the pronunciation and himself discovered the rules. Reference book "The three wishes " for additional documents for the process of teaching English to the children.
A comparison of three adaptive behaviour measures in relation to cognitive level and severity of autism compared the relationship between three measures of adaptive behaviour on the one hand, and cognitive level and severity of autism on the other. Strong positive correlations were found between MA and adaptive skills on all three measures.
Three diterpenoids with ent-kaur-16-ene skeleton, namely, ent-11 -acetoxy-7,14 - dihydroxykaur-16-en-15-one, ent-18-hydroxykaur-16-ene and ent-kaur-16-en-15-oxo-18-oic acid were isolated from the MeOH extract of the dried leaves of Croton tonkinensis Gagnep. (Euphorbiaceae) by successive chromatographic separation on silica gel, ODS gel and HPLC on ODS. Their structures were established on the basis of spectroscopic analyses.
Today, nano composite material is being studied and widely used for defence security and economic development. Keeping researching on the mechanic of three-phases nano composite in which two-phases is grains of pad and the structure of one-phase in reinforced two-phases is a nano structure, basing on consideration for interaction of the polyme matrix and grains of padding, we have defined engineering constants of the three-phases polyme composite nano material.
In the early 1990s, patterns in terrorism began to change. In particular, while the number of terrorist events was declining, the lethality was growing. This growth in terrorism was largely fueled by religious and millennial motivations. Three years after September 11, many studies by scores of institutions have been undertaken to
Replication of DNA is essential for the propagation of life. It is somewhat
surprising then that, despite the vital nature of this process, cellular organ-isms show a great deal of variety in the mechanisms that they employ to
ensure appropriate genome duplication. This diversity is manifested along
classical evolutionary lines, with distinct combinations of replicon architec-ture and replication proteins being found in the three domains of life: the
Bacteria, the Eukarya and the Archaea.
In modeling the structure of task-related discourse using plans, it is important to distinguish between plans that the agent has adopted and is pursuing and those that are only being considered and explored, since the kinds of utterances arising from a particular domain plan and the patterns of reference to domain plans and movement within the plan tree are quite different in the two cases.
In this paper, we demonstrate three NLP applications of the BioLexicon, which is a lexical resource tailored to the biology domain. The applications consist of a dictionary-based POS tagger, a syntactic parser, and query processing for biomedical information retrieval. Biological terminology is a major barrier to the accurate processing of literature within biology domain. In order to address this problem, we have constructed the BioLexicon using both manual and semiautomatic methods. We demonstrate the utility of the biology-oriented lexicon within three separate NLP applications. ...
We study a simple three-lane cellular automaton, based upon the well known NagelSchreckenberg model, and examine the effect of slow cars in such a system. We point out the important parameters defining the shape of the fundamental digram for the three-lane model and compare it to that of a two-lane one, showing the new mode of interactions between lanes. It is possible to reduce the influence of slow cars by choosing an adequate version of the symmetry with respect to lanes.
This dissertation empirically investigates the potential lead lag relationship between spot and future markets in three South East Asian countries, namely Malaysia, Thailand and Singapore. It attempts to prove whether the lead–lag relationship exist between the two markets in each country individually and whether future market returns lead spot market returns in these countries.
Multiplanar 3D US imaging is thought to provide more spatial information and allow easier anatomic assessment than the conventional two-dimensional ultrasound imaging. Contrast- enhanced three-dimensional ultrasound (CE 3D US) imaging is a new medical imaging technique that uses reflections of microbubbles to clearly depict blood vessels and allows the images to be displayed spatially at different visual angles.
Lecture Electric circuit theory: Three-phase circuits include all of the following content: Introduction, three-phase source, three-phase load, three-phase circuit analysis, power in three-phase circuits.
Feature structures are informational elements that have been used in several linguistic theories and in computational systems for natural-language processing. A logicaJ calculus has been developed and used as a description language for feature structures. In the present work, a framework in three-valued logic is suggested for defining the semantics of a feature structure description language, allowing for a more complete set of logical operators. In particular, the semantics of the negation and implication operators are examined.
The quality of the part-of-speech (PoS) annotation in a corpus is crucial for the development of PoS taggers. In this paper, we experiment with three complementary methods for automatically detecting errors in the PoS annotation for the Icelandic Frequency Dictionary corpus. The ﬁrst two methods are language independent and we argue that the third method can be adapted to other morphologically complex languages. Once possible errors have been detected, we examine each error candidate and hand-correct the corresponding PoS tag if necessary. ...
A three-dimensional macroporous Cu/SnO2 composite anode sheet prepared via a novel method was prepared via a novel method that is based on selective reduction of metal oxides at appropriate temperatures. SnO2 particles were imbedded on the Cu particles within the three-dimensionally interconnected Cu substrate.
