The response of the marine diatom Phaeodactylum ,tricornutum to Fe deficiency was evaluated in the context of fundamental physiological models of growth and photosynthesis. Fe deficiency induced chlorosis, which decreased Chl a : C ratios and Chl a-specific light-saturated photosynthesis (P,“). In contrast to Pme, (Ye was slightly increased under Fe deficiency, and photosynthesis in Fedeficient...

The deficiency of a propositional formula F in CNF with n variables and m clauses is defined as m−n. It is known that minimal unsatisfiable formulas (unsatisfiable formulas which become satisfiable by removing any clause) have positive deficiency. Recognition of minimal unsatisfiable formulas is NP-hard, and it was shown recently that minimal unsatisfiable formulas with deficiency k can be reco...

In the paper, we apply a new approach to comparison of distributions sums random variables case Poisson sums. This was proposed in our previous work (Bening, Korolev, 2022) and is based on concept statistical deficiency. Here, introduce continuous analog under consideration, by deficiency, will mean difference between parameter distribution number summands sum that compound providing desired ac...

In this chapter and the next, we consider algorithms for optimization problems. We have already seen an example of an optimization problem — the maximum subsequence sum problem from Chapter 1. We can characterize optimization problems as admitting a set of candidate solutions. In the maximum subsequence sum problem, the candidate solutions are the contiguous subsequences in the input array. An ...

A subset A of a given finite abelian group G is called (k, l)-sum-free if the sum of k (not necessarily distinct) elements of A does not equal the sum of l (not necessarily distinct) elements of A. We are interested in finding the maximum size λk,l(G) of a (k, l)-sum-free subset in G. A (2, 1)-sum-free set is simply called a sum-free set. The maximum size of a sum-free set in the cyclic group Z...

OBJECTIVE In order to evaluate micronutrient status of children aged 24-60 months living in rural disaster areas after one year of the earthquake in Wenchuan. DESIGN After one year of Wenchuan Earthquake, using PPS sampling methods, a total of 270 children from six-randomized townships near seismic center, in each township sample size consisted of 30 to 50 children, were sampled for evaluatin...

In this paper, some results of the Chebyshev type integral inequality for the pseudo-integral are proven. The obtained results, are related to the measure of a level set of the maximum and the sum of two non-negative integrable functions. Finally, we applied our results  to the case of comonotone functions.
