I haven’t added an example of how you implement migrations with Kitten’s¹ built-in JSDB database² yet but here’s one that I just used when renaming a field (property) in a table (JavaScript object) from “account” to “data” that illustrates the general granular approach you should take within persisted instances of JavaScript classes.
This is, of course, an advanced use case of the built-in JavaScript database that all Kitten apps have.
Kitten is simple for simple use cases. So ch…

sp_high_school_new: High school dynamic contacts (2011-2012)
These datasets contain the temporal network of contacts between students in a high school in Marseilles, France. The first dataset gives the contacts of the students of three classes during 4 days in Dec. 2011, and the second corresponds to the contacts of the students of 5 classes during 7 days (from a Monday to the Tuesday of the following week) in Nov. 2012.
This network has 126 nodes and 28561 edges.

Just finished "Concrete Rose" by Angie Thomas (I haven't yet read "The Hate U Give" but that's now high on my list of things to find). It's excellent, and in particular, an excellent treatise on positive masculinity in fiction form. It's not a super easy book to read emotionally, but is excellently written and deeply immersive. I don't have the perspective to know how it might land among teens like those it portrays, but I have a feeling it's true enough to life, and it held a lot of great wisdom for me.
CW for the book include murder, hard drugs, and parental abandonment.
I caught myself in a racist/classist habit of thought while reading that others night appreciate hearing about: early on I was mentally comparing it to "All my Rage" by Sabaa Tahir and wondering if/when we'd see the human cost of the drug dealing to the junkies, thinking that it would weaken the book not to include that angle. Why is that racist/classist? Because I'm always expecting books with hard drug dealers in them to show the ugly side of their business since it's been drilled into me that they're evil for the harm they cause, yet I never expect the same of characters who are bankers, financial analysts, health insurance claims adjudicators, police officers, etc. (Okay, maybe I do now look for that in police narratives). The point is, our society includes many people who as part of their jobs directly immiserate others, so why and I only concerned about that misery being brought up when it's drug dealers?

The Trump administration is not attacking the "excesses" of "woke" scholarship. They're at war with the very idea of power analysis, with the feeling of deep empathy with the oppressed, with ethical commitment to make a just world.

Hybrid pipe dreams for the lower-upper scheme
In [KU23] were introduced hybrid pipe dreams interpolating between classic and bumpless pipe dreams, each hybridization giving a different formula for double Schubert polynomials. A bijective proof was given (following [GH23]) of the independence of hybridization, but only for nonequivariant Schubert polynomials. In this paper we further generalize to hybrid generic pipe dreams, replacing the bijective proof of hybridization-independence with a Yang-Baxter-based proof that allows one to maintai…

On three classes of logarithmic integrals
In this paper, we evaluate the following families of definite integrals in closed form and we show that they are expressible only in terms of the dilogarithm function and the inverse tangent integral, and elementary functions. \begin{equation*} \int_{0}^{1}\frac{\log\big(x^m+1\big)}{x+1}\thinspace{\rm d}x \quad \mbox{and}\quad \int_{0}^{1}\frac{\log\big(x^m+1\big)}{x^2+1}\thinspace{\rm d}x, \end{equation*} where $m$ is a positive odd integer. When $m$ is a positive even integer, these integrals…

Degenerate systems of three Brownian particles with asymmetric collisions: invariant measure of gaps
We consider a degenerate system of three Brownian particles undergoing asymmetric collisions. We study the gap process of this system and focus on its invariant measure. The gap process is described as an obliquely reflected degenerate Brownian motion in a quadrant. For all possible parameter cases, we compute the Laplace transform of the invariant measure, and fully characterize the conditions under which it belongs to the following classes: rational, algebraic, differentially finite, or diffe…

Photonic Simulation of Beyond-Quantum Nonlocal Correlations (e.g. Popescu-Rohrlich Box) with Non-Signaling Quantum Resources

Photonic Simulation of Beyond-Quantum Nonlocal Correlations (e.g. Popescu-Rohrlich Box) with Non-Signaling Quantum Resources
Bell nonlocality exemplifies the most profound departure of quantum theory from classical realism. Yet, the extent of nonlocality in quantum theory is intrinsically bounded, falling short of the correlations permitted by the relativistic causality (the no-signaling) principle. A paradigmatic example is the Popescu-Rohrlich correlation: two distant parties sharing arbitrary entanglement cannot achieve this correlation, though it can be simulated with classical communication between them. Here we…
