#### Avoiding approximate repetitions with respect to the longest common subsequence distance

(Mathematical Sciences Publishers, 2015-09-17)

Ochem, Rampersad, and Shallit gave various examples of infinite words avoiding what they called approximate repetitions. An approximate repetition is a factor of the form x x', where x and x' are close to being identical. ...

#### Mathematical Concepts and Proofs from Nicole Oresme: Using the History of Calculus to Teach Mathematics

(2005)

This paper examines the mathematical work of the French bishop, Nicole Oresme (c. 1323–1382), and his contributions towards the development of the concept of graphing functions and approaches to investigating infinite ...

#### Regular Two-Graphs and Equiangular Lines

(University of Winnipeg, 2004)

Regular two-graphs are antipodal distance-regular double coverings of the complete graph, and they have many interesting combinatorial properties. We derive a construction for regular two-graphs containing cliques of ...

#### Multi-dimensional sets recognizable in all abstract numeration systems

(EDP Sciences, 2011)

We prove that the subsets of Nd that are S-recognizable for all abstract numeration systems S are exactly the 1-recognizable sets. This generalizes a result of Lecomte and Rigo in the one-dimensional setting.

#### Avoidability index for binary patterns with reversal

(2017)

For every pattern p over the alphabet {x,x^R,y,y^R}, we specify the least k such that p is k-avoidable.

#### A direct proof of a result of Thue

(Utilitas Mathematica, 1984)

#### The Aveline's Hole 9 Cranium: A Partial Solution to a Long Standing Enigma

(University of Bristol Spelaeological Society, 2012)

Aveline's Hole is both one of the best-known sites with early human skeletal material in Britain and one of the most problematic in its history. First discovered and explored at the close of the 18th century, it yielded ...

#### Supporting Teachers in Times of Change: The Job Demands- Resources Model and Teacher Burnout During the COVID-19 Pandemic

(RedFame, 2020-10)

Burnout in teachers has been broadly investigated, but no studies have investigated burnout in teachers during a pandemic. The current study is based on a survey of 1278 Canadian teachers and examined whether the Job ...

#### Square-free Words with Square-free Self-shuffles

(The Electronic Journal of Combinatorics, 2014-01-12)

We answer a question of Harju: For every n ≥ 3 there is a square-free ternary word of length n with a square-free self-shuffle.

#### The Brachistochrone Problem: Mathematics for a Broad Audience via a Large Context Problem

(Montana Council of Teachers of Mathematics & Information Age Publishing, 2008)

Large context problems (LCP) are useful in teaching the history of science. In this article we consider the brachistochrone problem in a context stretching from Euclid through the Bernoullis. We highlight a variety of ...
