Summation formulae on reciprocal sequences

European Journal of Combinatorics, 2007
Given a sequence \(\{a_n\}_{n\geq0}\) of complex numbers, the reviewer [Eur. J. Comb. 24, 709--718 (2003; Zbl 1024.05010)] introduced its dual sequence \(\{a_n^*\}_{n\geq0}\) with \(a_n^*=\sum_{k=0}^n\binom {n}{k}(-1)^ka_k\), and set \[ A_n(x)=\sum_{k=0}^n\binom{n}{k}(-1)^ka_kx^{n-k}\quad \text{and}\quad A_n^*(x)=\sum_{k=0}^n\binom{n}{k}(-1)^ka_k^*x^{n-

EXACT FORMULA FOR DISTRIBUTION OF SEQUENCES {ωn} [PDF]

International Journal of Number Theory, 2012
An exact formula for distribution of sequences of fractional parts is proved. This provides us with a possibility for computational study of their discrepancies by the means of integer-number programming.

Polyfactoriality as a Defining Criterion of Formulaic Speech

Journal of Linguistics and Language Teaching, 2020
Starting from the observation that the criteria generally applied to the definition of formulaic speech – polylexicality, (relative) stability and idiomaticity – no longer reflect the current state-of-the-art insight into the nature of prefabricated ...

The Effect of Teaching Formulaic Sequences through Spaced and Non-spaced Retrievals on Iranian EFL Learners' Oral Fluency [PDF]

Journal of English Language Teaching and Learning, 2019
Formulaic sequences (FSs) are among the most commonly discussed and well-documented effective factors in oral fluency both in L1 and L2. The present study aims to investigate the effect of teaching a set of 140 FSs on Iranian EFL learners' oral fluency ...

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

A Comparative Study on the Irrigation Suitability of Kerala's Rivers Using Fuzzy AHP and Conventional Methods

Irrigation and Drainage, EarlyView.
ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

Additive representation in thin sequences, III: asymptotic formulae [PDF]

Acta Arithmetica, 2001
This paper continues the series opened in [Ann. Sci. Éc. Norm. Supér., IV. Sér. 34, 471-501 (2001; Zbl 1020.11062)], to which readers are referred for an overview of the strategy followed. The aim is to show that an expected asymptotic formula holds for the number of representations of a number in a specified form, and this for almost all occurrences ...
