Growing Mathlib: maintenance of a large scale mathematical library
The Lean mathematical library Mathlib is one of the fastest-growing libraries of formalised mathematics. We describe various strategies to manage this growth, while allowing for change and avoiding maintainer overload. This includes dealing with breaking changes via a deprecation system, using code quality analysis tools (linters) to provide direct user feedback about common pitfalls, speeding up compilation times through conscious library (re-)design, dealing with technical debt as well as wri…

Limitations of detecting structural changes and time-reversal symmetry breaking in scanning tunneling microscopy experiments
The family of kagome superconductors $A$V$_3$Sb$_5$ ($A$=K, Cs, Rb) is an exciting playground for investigating various density waves, unusual superconductivity and a surprising time-reversal symmetry breaking despite the absence of spin magnetism. The origin of time-reversal symmetry breaking has been of particular interest, and conflicting results have been intensely debated. Scanning tunneling microscopy (STM) provided crucial evidence by the observation that apparent chirality associated wi…

Breaking Barriers in Health Monitoring: Multi-Scenario Vital Sign Detection Using Mm-Wave MIMO FMCW Radar
This paper explores the deployment of mm-wave Frequency Modulated Continuous Wave (FMCW) radar for vital sign detection across multiple scenarios. We focus on overcoming the limitations of traditional sensing methods by enhancing signal processing techniques to capture subtle physiological changes effectively. Our study introduces novel adaptations of the Prony and MUSIC algorithms tailored for real-time heart and respiration rate monitoring, significantly advancing the accuracy and reliability…

I have a definite love-hate relationship with vulkan-hpp. Not using raw C vulkan calls is super nice...
But sudden build failures with no warning due to them making breaking changes to function return types? Not so nice. They seem to feel they can make breaking changes freely at any time and don't do a great job of documenting said changes.

US solar plant construction faces obstacles under current administration, hindering progress towards a sustainable future. Despite challenges, clean power plants offer hope for industry growth. #climatechange #climatesolutions

US solar plant construction is on a record-breaking spree — for now
Solar power is having a bumper year as developers race to complete installations before Trump's policy changes pull the rug out from under the industry.

What You See Is What It Does: A Structural Pattern for Legible Software
The opportunities offered by LLM coders (and their current limitations) demand a reevaluation of how software is structured. Software today is often "illegible" - lacking a direct correspondence between code and observed behavior - and insufficiently modular, leading to a failure of three key requirements of robust coding: incrementality (the ability to deliver small increments by making localized changes), integrity (avoiding breaking prior increments) and transparency (making clear what has c…

Looks like I have this to investigate now because a warning is appearing on my admin dashboard. Whatever the problem is seems to affect Elasticsearch 7.17.23 and Mastodon 4.4.2 , because this never appeared on Mastodon 4.3.x and the suggested command only returns this error:

The Free Massive Quadratic Action from the Exotic Model (E7)

The Free Massive Quadratic Action from the Exotic Model (E7)
The Exotic Model arises from adding a special exotic invariant to the Supersymmetric Standard Model. The Exotic Model has a supersymmetry violating mass spectrum without using spontaneous or explicit breaking of supersymmetry. The splitting arises with gauge symmetry breaking, at tree level, in the supermultiplets of the Z vector boson and a new X vector boson. It spreads to the other particles at one loop. This mass splitting is possible because the exotic invariant changes the algebra of supe…

Reply to "Limitations of detecting structural changes and time-reversal symmetry breaking in scanning tunneling microscopy experiments"
In their comment, the authors attribute our observations of light- and magnetic-field-induced manipulation of the CDW state in RbV3Sb5 to random experimental artifacts such as tip changes, drift, and scan conditions, concluding that no intrinsic effect exists. In this reply, we clarify three points. First, our reported magnetic-field-induced CDW switching has been independently replicated in multiple STM studies and corroborated by transport measurements. Second, in our data, the switching of C…

Topological Strings in SU(3) Gauge Theory at Finite Temperature
We investigate string configurations in the deconfined phase of SU(3) gauge theory, which arise from the spontaneous breaking of the $Z_3$ center symmetry. These configurations form at the junctions of domain walls of the theory. The complex phase of the Polyakov loop changes by multiples of $2π$ on large spatial loops around the string, rendering them topologically stable. Using the Monte Carlo simulations of the partition function, we compute the free energy associated with these configurati…
