Optimal Packings of 13 and 46 Unit Squares in a Square [PDF]
Let $s(n)$ be the side length of the smallest square into which $n$ non-overlapping unit squares can be packed. We show that $s(m^2-3)=m$ for $m=4,7$, implying that the most efficient packings of 13 and 46 squares are the trivial ones.

Remyelination varies between and within lesions in multiple sclerosis following bexarotene
Objective In multiple sclerosis chronic demyelination is associated with axonal loss, and ultimately contributes to irreversible progressive disability. Enhancing remyelination may slow, or even reverse, disability. We recently trialled bexarotene versus

Tiling the unit square with squares and rectangles
Call a rectangle small if it will fit inside the unit square; call a rectangle binary if its dimensions are powers of 2. Theorem 1. If \({\mathcal S}\) is a set of small binary squares having total area greater than 1, some finite subset of \({\mathcal S}\) will tile the unit square. Theorem 2.

Expression Pattern of a Mini Human PrP Gene Promoter in Transgenic Mice
The prion protein is central to the pathogenesis of prion diseases, although its exact function remains unclear. Although transgenic mice have been widely utilised in prion research, their PrP expression patterns have not been characterised in detail. We

Exploring the effectiveness of a COVID-19 contact tracing app using an agent-based model
A contact-tracing strategy has been deemed necessary to contain the spread of COVID-19 following the relaxation of lockdown measures. Using an agent-based model, we explore one of the technology-based strategies proposed, a contact-tracing smartphone app.

IntroductionConventional MRI is routinely used for the characterization of pathological changes in multiple sclerosis (MS), but due to its lack of specificity is unable to provide accurate prognoses, explain disease heterogeneity and reconcile the gap ...

The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Opinion: more mouse models and more translation needed for ALS
Amyotrophic lateral sclerosis is a complex disorder most of which is ‘sporadic’ of unknown origin but approximately 10% is familial, arising from single mutations in any of more than 30 genes.
