The behavior of electronic states of one dimensional correlated disordered systems which are modelled by a tight binding Hamiltonian is studied analytically using the invariant measure method. The approach of Bovier is generalized to include the possibility of different site energies and nearest neighbor hopping integrals inside the correlated sites or the cluster. The process is further elabor...
Abstract A prolonged drought affected Western Europe and the Mediterranean region in 2022 producing large socio-ecological impacts. The role of anthropogenic climate change (ACC) exacerbating this has been often invoked public debate, but link between atmospheric circulation ACC not received much attention so far. Here we address question by applying method analogs, which allows us to identify ...
Learning logic of exceptions is a substantial challenge in data mining and knowledge discovery. Exceptional phenomena detection takes place among huge records in a database which contains a large number of normal records and a few of exceptional ones. This is important to promote the confidence to a limited number of exceptional records for effective learning. In this study, a new approach base...
Study on land ecological safety has become a forefront topic of regional sustainable development. The paper constructed an evaluation index system of land ecological safety. Then it discussed the ranges of indexes corresponding to each evaluation grade. Considering the illegibility and uncertainty in land ecological safety evaluation, the paper combined fuzzy matter-element and entropy method t...
The paper [FGS] uses the classification of finite simple groups and covering theory in positive characteristic to solve Carlitz’s conjecture (1966). We consider only separable polynomials; their derivative is nonzero. Then, f ∈ Fq [x] is exceptional if it acts as a permutation map on infinitely many finite extensions of the finite field Fq , q = pa for some prime p. Carlitz’s conjecture says f ...
The aim of this study was to compare the Exceptional Student Learning English (ESLE) web application and traditional application and the evaluation of the ESLE app mainly from the exceptional student parents' perspective. To this end, five exceptional student parents with their exceptional children were selected among 30 parents in Isfahan in Isfahan province. Open-ended questionnaires were sen...
Plasticity in developmental programming has evolved in order to provide the best chances of survival and reproductive success to the organism under changing environments. Environmental conditions that are experienced in early life can profoundly influence human biology and long-term health. Developmental origins of health and disease and life-history transitions are purported to use placental, ...
