Improved Packings of $n(n − 1)$ Unit Squares in a Square [PDF]

The Electronic Journal of Combinatorics, 2021
Let $s(n)$ be the side of the smallest square into which we can pack $n$ unit squares. The purpose of this paper is to prove that $s(n^2-n)<n$ for all $n\geq 12$. Besides, we show that $s(18^2-17) < 18, s(17^2-16) < 17,$ and $s(16^2-15) < 16.$

Experimental and numerical validation of Advanced Statistical Energy Analysis to incorporate tunneling mechanisms for vibration transmission across a grillage of beams

Acta Acustica, 2022
Advanced Statistical Energy Analysis (ASEA) is used to predict vibrational response on a three-bay linear grillage of beams that supports multiple wave types when there is significant indirect coupling through tunneling mechanisms.

High-Yield Mucosal Olfactory Ensheathing Cells Restore Loss of Function in Rat Dorsal Root Injury

Cells, 2021
In a previous study, we reported that no axons were crossing from the severed dorsal roots to the spinal cord using the rat dorsal rhizotomy paradigm. The injury caused ipsilateral deficits of forepaw function.

The impact of visualization on flexible Bayesian reasoning

Avances de Investigación en Educación Matemática, 2017
There is wide consensus that visualizations of statistical information can support Bayesian reasoning. This article focusses on the conceptual understanding of Bayesian reasoning situations and investigates whether the tree diagram or the unit square is

Friedreich's Ataxia Frequency in a Large Cohort of Genetically Undetermined Ataxia Patients

Frontiers in Neurology, 2021
Background: Patients with suspected genetic ataxia are often tested for Friedreich's ataxia (FRDA) and/or a variety of spinocerebellar ataxias (SCAs). FRDA can present with atypical, late-onset forms and so may be missed in the diagnostic process.

Inefficiency in packing squares with unit squares

Journal of Combinatorial Theory, Series A, 1978
AbstractIt is shown that, in packing a square of side n + 12 with unit squares, the wasted space always has area ⪢ n12. This answers a question of Erdös and Graham.

Global unit squares and local unit squares

Journal of Number Theory, 2008
Let \(K\) be any Galois extension of \(\mathbb Q\), and \(U_K\) be the unit group of \(K\). For any place \(v\) of \(K\), let \(U_v\) be the group of local units of \(K_v\). Here the authors study the following problem: does there exist an odd prime \(p\) such that the map \(U_K/U_K^2\to \prod_{v\mid p} U_v/U_v^2\) is injective.
