It is an oft-quoted fact that there is much in common between the fields of music and mathematics. This paper seeks to examine that commonality through the use of information theory techniques, specifically, entropy as defined by Shannon. The analysis will be presented through the process of creating an entropy table for a collection of Chopin’s Nocturnes. The method for generating a random str...

The Adonis ladybird, Hippodamia variegataGoeze (Coleoptera: Coccinellidae) is known as an important predator of the Common pistachio psylla, Agonoscena pistaciae Burckhardt & Lauterer (Hemiptera: Psyllidae). Despite using the selective pesticides to manage the pests in the pistachio orchards, these chemicals have influenced non-target organisms like predators and parasitoids. ...

Traditional Chinese medicine (TCM) treats qi as the core of the human life systems. Starting with a hypothetical correlation between TCM qi and the entropy theory, we address in this article a holistic model for evaluating and unveiling the rule of TCM life systems. Several new concepts such as acquired life entropy (ALE), acquired life entropy flow (ALEF) and acquired life entropy production (...

In this paper, we propose a novel method for increasing the entropy of a sequence of independent, discrete random variables with arbitrary distributions. The method uses an auxiliary table and a novel theorem that concerns the entropy of a sequence in which the elements are a bitwise exclusive-or sum of independent discrete random variables.

-the cowpea aphid, aphis craccivora koch, is an important pest of robinia pseudoacacia frisia. life table parameters of a. craccivora were determined under natural (16- 33ºc and 32-89% rh, respectively) and laboratory (25 ± 1ºc, rh of 70 ± 5% and a photoperiod of 16:8 h (l: d) conditions. the data were analyzed using the age-stage, two-sex life table theory. each experiment was replicated 45 ti...

background: northern regions of iran have been encountered to dominate malignancies of gastrointestinal (gi) tract. we came to examine the total excess mortality due to the gi cancer in mazandaran province. methods: socio-demographic and clinical data of 484 patients with gi cancer collected during the years 1990-1991were available from babol cancer registry. patients were followed up for 15 ye...

life table parameters of aphis pomi degeer (hemiptera: aphididae) were determined on two host plants: apple (malus pumila l.) and flowering quince (chaenomeles japonica lindl.). this study was carried out under laboratory conditions (25 ± 1 ºc and rh of 70 ± 5 % and a photoperiod of 16: 8 h (l: d). the survivorship from first instar nymphs to adult was very close in m. pumila and c. japonica. t...

We correct the errors in two tables. Table 3, rows 2 and 3 should have the consensus coefficient of 0.32 and 0.58 instead of the 0.30 and 0.51. Table 4 should have a consensus coefficient of 0.69 instead of 0.57. The entropy coefficients in Table 1, rows C and D, are 2.32 and 2.23 instead of 1.86 and 1.73. The authors regret any confusion readers might have had with the incorrect numbers.

Actuaries and demographers have a long tradition of using collateral data to improve mortality estimates. Three main approaches have been used to accomplish the improvement — mortality laws, model life tables, and relational methods. The present paper introduces a regression model that incorporates all of the beneficial principles from each of these approaches. The model is demonstrated on mort...
