Did I ever mention that #TallBikesArePractical? Because they are!
I mean how else would I carry this additional childs bike along with me? 🤷 🤣

The extended code for a class of generalized Roth-Lempel codes and their properties
As we all know, many interesting and important codes are obtained by modifying or combining existing codes. In this paper, we focus on generalized Roth-Lempel (in short, GRL) codes and define a class of extended codes, i.e., the extended generalized Roth-Lempel (in short, EGRL) code. And then for a special class of EGRL codes, we give a parity-check matrix and establish a necessary and sufficient condition for the EGRL code or its dual code to be MDS or AMDS, respectively. Finally, we construct…

Improving 8x8 TeraFET array sensitivity through liquid-nitrogen cooling in a compact low-noise cryostat
The sensitivity of antenna-coupled field-effect transistors (TeraFETs) to terahertz (THz) radiation has been shown to improve continuously with decreasing temperature. In this work, we first present a quantitative evaluation of the temperature-dependent noise-equivalent power (NEP) of recently developed patch-antenna-coupled TeraFET detectors resonant at 540 GHz, with measurements down to 20 K. Based on these results, we project NEP values approaching 1 to 2 pW/$\sqrt{\textrm{Hz}}$ under effici…

On finite extensions of lamplighter groups
We study a family of groups consisting of the simplest extensions of lamplighter groups. We use these groups to answer multiple open questions in combinatorial group theory, providing groups that exhibit various combinations of properties: 1) Decidable Subgroup Membership and undecidable Uniform Subgroup Membership Problem, 2) Rational volume growth series and undecidable Word Problem and 3) Recursive (even context-free) language of conjugacy geodesics, decidable Word Problem, and undecidable C…

I used the #PrincessLamplighter for a trip to the grocery store, which I recorded on #Strava or … actually I should say that I tried to record it. The recording failed, thus it is not on Strava and as all Strava users know, that means it never actually happened and so my family wi…

Why do I refer to the bike as a "lamplighter"? In the old days lamp lighting was a job. A lamp lighter went around in the evening usually with a ladder and lit up each gas powered lamp post in turn.
Some of the people doing this job had specialist bikes made that were very tall. Then they could just cycle between each one, hold on (or lean) and light them without needing the ladder.
The design here is classic lamplighter bike style, albeit scaled down. A real lamplight…

The scale is all off. I can't work out if this is a normal chair and tiny bike, or big bike and enormous chair? 🤔
