@arXiv_mathLO_bot@mastoxiv.pageSpeedability of computably approximable reals and their approximations
George Barmpalias, Nan Fang, Wolfgang Merkle, Ivan Titov
https://arxiv.org/abs/2603.26484 https://arxiv.org/pdf/2603.26484 https://arxiv.org/html/2603.26484
arXiv:2603.26484v1 Announce Type: new
Abstract: An approximation of a real is a sequence of rational numbers that converges to the real. An approximation is left-c.e. if it is computable and nondecreasing and is d.c.e. if it is computable and has bounded variation. A real is computably approximable if it has some computable approximation, and left-c.e. and d.c.e. reals are defined accordingly.
An approximation $\{a_s\}_{s \in \omega}$ is speedable if there exists a nondecreasing computable function $f$ such that the approximation $\{a_{f(s)}\}_{s \in \omega}$ converges in a certain formal sense faster than $\{a_s\}_{s \in \omega}$. This leads to various notions of speedability for reals, e.g., one may require for a computably approximable real that either all or some of its approximations of a specific type are speedable.
Merkle and Titov established the equivalence of several speedability notions for left-c.e. reals that are defined in terms of left-c.e. approximations. We extend these results to d.c.e. reals and d.c.e. approximations, and we prove that in this setting, being speedable is equivalent to not being Martin-L\"{o}f random. Finally, we demonstrate that every computably approximable real has a computable approximation that is speedable.

arXiv:2602.06860v1 Announce Type: new
Abstract: Range queries are simple and popular types of queries used in data retrieval. However, extracting exact and complete information using range queries is costly. As a remedy, some previous work proposed a faster principle, {\em approximate} search with range queries, also called single range cover (SRC) search. It can, however, produce some false positives. In this work we introduce a new SRC search structure, a $c$-DAG (Directed Acyclic Graph), which provably decreases the average number of false positives by logarithmic factor while keeping asymptotically same time and memory complexities as a classic tree structure. A $c$-DAG is a tunable augmentation of the 1D-Tree with denser overlapping branches ($c \geq 3$ children per node). We perform a competitive analysis of a $c$-DAG with respect to 1D-Tree and derive an additive constant time overhead and a multiplicative logarithmic improvement of the false positives ratio, on average. We also provide a generic framework to extend our results to empirical distributions of queries, and demonstrate its effectiveness for Gowalla dataset. Finally, we quantify and discuss security and privacy aspects of SRC search on $c$-DAG vs 1D-Tree, mainly mitigation of structural leakage, which makes $c$-DAG a good data structure candidate for deployment in privacy-preserving systems (e.g., searchable encryption) and multimedia retrieval.

Abstract: The n2EDM experiment at the Paul Scherrer Institute aims to conduct a high-sensitivity search for the electric dipole moment of the neutron. Magnetic stability and control are achieved through a combination of passive shielding, provided by a magnetically shielded room (MSR), and a surrounding active field compensation system by an Active Magnetic Shield (AMS). The AMS is a feedback-controlled system of eight coils spanned on an irregular grid, designed to provide magnetic stability to the enclosed volume by actively suppressing external magnetic disturbances. It can compensate static and variable magnetic fields up to $\pm 50$ $\mu$T (homogeneous components) and $\pm 5$ $\mu$T/m (first-order gradients), suppressing them to a few $\mu$T in the sub-Hertz frequency range. We present a full finite element simulation of magnetic fields generated by the AMS in the presence of the MSR. This simulation is of sufficient accuracy to approach our measurements. We demonstrate how the simulation can be used with an example, obtaining an optimal number and placement of feedback sensors using genetic algorithms.

@thomasfuchs@hachyderm.ioNone of the "code generation" stuff is new by the way.
The tech industry has tried to speed up coding and increase software output for the last 3 to 4 decades, by various means; e.g. Rapid Application Development, Expert Systems, Object-Oriented Programming, thousands of different frameworks all the way to trying to off-shore development and exploit third-world labor.
The problem with this is: there is no software scarcity. Pretending that "we can't make software fast enough" is a red herring to hide the fact that making (good) software is 90% painstaking research, design, planning, marketing and talking to and supporting customers.
And 10% writing the actual code—the C-suite is doing ye olde "trying to find a technical solution to a social problem".

Abstract: We propose two efficient algorithms for generating uniform random directed acyclic graphs, including an asymptotically optimal exact-size sampler that performs $\frac{n^2}{2} o(n^2)$ operations and requests to a random generator. This was achieved by extending the Boltzmann model for graphical generating functions and by using various decompositions of directed acyclic graphs. The presented samplers improve upon the state-of-the-art algorithms in terms of theoretical complexity and offer a significant speed-up in practice.

The table first gives the elongation (angle between comet and Sun in the sky) and the phase angle (the angle Sun - comet - Earth) which nearing 180° can lead to significant boost of brightness by forward scattering on dust.
And this is followed by the altitude of the comet at the solar depressions given in the top line, for Bochum and Windhoek: sunset and end of civilian twilight and for the latter also the end of nautical and astronomical twilight, i.e. the onset of night. Also of importance is the angle of a hypothetical dust tail (simulated in https://hdr-astrophotography.com) after perihelion, also much better in the South: https://britastro.org/section_news_item/c-2026-a1-maps-a-kreutz-group-sungrazer - but first MAPS has to survive the latter *and* release a lot of dust at the right time ...

@BBC6MusicBot@mastodonapp.uk @cdarwin@c.imA Swiss canton has suspended its pilot of electronic voting after failing to count 2,048 votes cast in national referendums held on March 8.
Basel-Stadt announced the problem with its e-voting pilot, open to about 10,300 locals living abroad and 30 people with disabilities, last Friday afternoon.
It encouraged participants to deliver a paper vote to the town hall or use a polling station but admitted this would not be possible for many.
By the close of polling on Sunday, its …

That’s the practical result of the Trump administration’s yearlong parade of regulatory rollbacks,
capped on Thursday by its killing of the “endangerment finding,”
the scientific determination that required the Environmental Protection Agency to regulate greenhouse gases because of the threat to human health.
“The U.S. no longer has em…

@cdarwin@c.imA federal judge in Boston on Monday stalled major parts of health secretary Robert F. Kennedy Jr.’s campaign to remake vaccine policy in the U.S.,
saying the Trump administration had likely violated the law.
Judge Brian E. Murphy issued a preliminary ruling finding that Kennedy’s reconstitution of a key vaccine advisory panel,
