Archaeological Prospection, EarlyView.ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.

$\alpha$-additive functions and uniform distribution modulo one
Proceedings of the Japan Academy, Series A, Mathematical Sciences, 1984 Every nonnegative integer n can be written in the form \(n=\sum^{\infty}_{k=0}\epsilon_ k(n)z_ k\), where \(z_ k\) is the sequence of denominators of the convergents of the continued fraction expansion of a given irrational \(\alpha =[a_ 0;a_ 1,a_ 2,...]\), \(\epsilon_ 0(n)\in \{0,1,...,a_ 1-1\}\), \(\epsilon_ k(n)\in \{0,1,...,a_{k+1}\}\) (k\(\geq 1)\)

Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

On Matrix‐Based Cryptography Using Matrix Norm and Special Integer Sequences
Mathematische Nachrichten, EarlyView.ABSTRACT In this paper, a novel matrix‐based encryption approach based on the Affine Hill cipher is presented. The key matrix is constructed using the Narayana integer sequence, and the Frobenius norm of the key matrix is used as a scaling factor in the key construction.

Improving String Matching through Enhanced Hashing
Software: Practice and Experience, EarlyView.ABSTRACT Background Hashing offers opportunities to tune string matching algorithms while enabling efficient data retrieval and pattern detection. Many of the best algorithms apply hashing. Objective We try to develop faster online algorithms for exact string matching.

Social and emotional pathways to shame reduction: An RCT with preservice teachers
British Journal of Educational Psychology, EarlyView.Abstract Background Shame is an unpleasant, activating emotion that has been shown to undermine learners' motivation and achievement and identity development in mathematics education. Recent studies have implemented positive psychology interventions (PPIs) to reduce preservice teachers' shame in mathematics, with promising quantitative outcomes ...
