On boundary degrees of freedom in three dimensional Anti-de Sitter spacetime and thermofield-double
We will give two representations for thermofield-double (TFD). The first representation is the well-known Kerr-BTZ black hole geometry, which is the solution of Einstein's equation. The second representation is a disjoint union of two circles, which is a solution to two copies of the Schwarzian theory. This representation, in particular, admits the reparametrization modes, which are absent in any two dimensional CFT on a torus, and are essential for (dis-)entangling the TFD. Since the two repre…

Nine circles of elastic brittle fracture: A series of challenge problems to assess fracture models
Since the turn of the millennium, capitalizing on modern advances in mathematics and computation, a slew of computational models have been proposed in the literature with the objective of describing the nucleation and propagation of fracture in materials subjected to mechanical, thermal, and/or other types of loads. By and large, each new proposal focuses on a particular aspect of the problem, while ignoring others that have been well-established. This approach has resulted in a plethora of mod…

Here’s the real actual definition of “artificial intelligence,” the true technical meaning in research and engineering circles when it’s not being used as marketing hype.
Artificial intelligence is anything that
1. humans are generally good at, and
2. computers were recently bad at.
That’s it. That’s all it means. You’ll hear people refine it and dress it up, but that’s the heart of the definition. (Check Wikipedia!)

It's been 7 months since the D-party lost the easiest-to-win election the US has ever had. And it's been 4 months since FFOTUS took office and became a modern Caligula.
And what has the D-party done?
Nada. Nada. Nada. The old faction is spinning in useless circles defending Biden's inexcusable decision to continue to run until too late. The younger element still shows no sign of engaging in the voting part of politics. Our middle-age element still looks first at t…

Edge Computing and its Application in Robotics: A Survey
The Edge computing paradigm has gained prominence in both academic and industry circles in recent years. By implementing edge computing facilities and services in robotics, it becomes a key enabler in the deployment of artificial intelligence applications to robots. Time-sensitive robotics applications benefit from the reduced latency, mobility, and location awareness provided by the edge computing paradigm, which enables real-time data processing and intelligence at the network's edge. While t…

Counting methods of area integrals and Tchebychev polynomials of second kind on the ellipse
We use Gronwall's area formula to find the area of some differents regions as circles, ellipses and lemniscates.We use Laurent and Taylor series expansions of conformal mapping from the exterior of the unit disk to either of these regions to compute the area of them.We close this work with the discussion of orthogonal Tchebychev polynomials of second kind on the ellipse and interpolation.

Discovery of Odd Radio Circles and Other Peculiars in the First Year of the EMU Survey using Object Detection
We present a systematic search for Odd Radio Circles (ORCs) and other unusual radio morphologies using data from the first year of the EMU (Evolutionary Map of the Universe) survey. ORCs are rare, enigmatic objects characterized by edge-brightened rings of radio emission, often found in association with distant galaxies. To identify these objects, we employ a hybrid methodology combining supervised object detection techniques and visual inspection of radio source candidates. This approach leads…

Closed Form for Half-Area Overlap Offset of 2 Unit Disks
The separation between the centers of two unit circles such that their overlapping area is exactly half of each's area is known to be around $0.8079455\dots$ (OEIS A133741). However, no closed form of this number is known. Here, we determine its closed form representation in terms of the inverse regularized beta function.

Envelopes of lines, unfoldings and breaking symmetry
We generalise the well-known ``embroidery'' envelopes of chords joining points at angles $t$ and $mt$ of a single circle in several ways. Firstly we allow $m$ to be rational (possibly negative) instead of integral, finding formulas for the number of cusps, points at infinity and self-intersections of these envelopes. Secondly we use two concentric circles instead of one, taking the chords to join a point of one circle to a point of the other. This construction allows the formation of different …

Homotopy types of Hom complexes of graph homomorphisms whose codomains are cycles
For simple graphs $G$ and $H$, the Hom complex $\mathrm{Hom}(G,H)$ is a polyhedral complex whose vertices are the graph homomorphisms $G\to H$ and whose edges connect the pairs of homomorphisms which differ in a single vertex of $G$. Hom complexes play an important role in an algebro-topological approach to the graph coloring problem. It is known that $\mathrm{Hom}(G,H)$ is homotopy equivalent to a disjoint union of points and circles when both $G$ and $H$ are cycles. We generalize this known r…

Minimal generating sets of groups of Kim-Manturov
We consider a series of groups defined by Kim and Manturov. These groups have their background in triangulations of a surface and configurations of points, lines or circles on the surface. They are expected to have relationships to many geometric objects. In this paper, we give a minimal generating set of the group and determine the abelianization. We also introduce some related groups which might be helpful to understand the structure of the original groups.

#Copilot "Think Deeper" mode is much more useful than Quick Response. For coding, it has a "Senior Dev" posture (even alludes to it) including saying "ping if you've a question" and talking vague, defensive BS in circles.
That's a ✅ on ego and mumbo-jumbo parts of senior dev.
