breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...

It has been shown that the sequence of Smith invariants defined by certain sequences of products of matrices, with entries in a local principal ideal domain, are combinatorially described by tableau-pairs (T, K) where T is a tableau of skew-shape which rectifies to the key-tableau K. It is a fact that the set of all shuffles of the columns of a key-tableau is a subset of its Knuth class. Here, ...

In this paper, we present a geometric method for describing the effects of the delay induced uncertainty on the stability of a standard Smith Predictor control scheme. The method consists of deriving the stability crossing curves in the parameter space defined by the nominal delay, and delay uncertainty, respectively. More precisely, we start by computing the crossing set, which consists of all...

Smith was a pioneer epidemiologist, bacteriologist, and pathologist who made many contributions to medical science that were of far-reaching importance. He is best known for his work on Texas cattle fever, in which he and his colleagues discovered the protozoan agent and its means of transmission by ticks. This was the ¿ rst time that an arthropod had been de¿ nitively linked with the transmiss...

In an open-ended contingent valuation (CV) survey, a respondent can state any non-negative valuation for a given good. As the set of possible responses is infinite, the GibbardSatterthwaite theorem implies that such a survey cannot be incentive-compatible. That is, participants in an open-ended CV survey have an incentive to increase their utility by misrepresenting their preferences. This natu...

In this study, Black, Macklem, and Rose thoroughly describe the outcomes when a wide range of reaction functions are set in CPAM, the Canadian Policy Analysis Model developed at the Bank of Canada. The reaction functions for monetary policy influence the short-term interest rate relative to the long-term rate. The analysis begins with the CPAM reaction function, which targets the expected diffe...

Sequence alignment is a task that calculates the degree of similarity between two sequences. Given a query sequence, finding a database sequence which is most similar to the query by sequence alignment is the first step in bioinformatics research. The first sequence alignment algorithm was proposed by Needleman and Wunsch. They got the optimal global alignment by using dynamic programming metho...
