On the convergence rate in the central limit theorem for linearly extended negative quadrant dependent random variables and its applications
In this paper, we establish the convergence rate in central limit theorem (CLT) for linearly extended negative quadrant dependent (LENQD) random variables (rv's). Under some weak conditions, the rate of normal approximation is shown as $O(n^{-1/9})$. As an application, the convergence rate in CLT of the wavelet estimator for the nonparametric regression model with LENQD errors is presented as $O(n^{-1/9})$. The performance of the main results is illustrated through a simulation study based on a…

Day 23: Thi Bui
Indirect CW: parental neglect, war, intergenerational trauma
Bui is the author of "The Best We Could Do", a graphic memoir which explores her relationship with her parents and unpacks some of the intergenerational trauma coming out of the Vietnam War. It has a lot of wisdom to offer about both dealing with troubled parents as a 1.5th-generation immigrant, and it delves deeply into her parents' histories in Vietnam and the complexities of the situation there both in the north and in the south. It's beautifully illustrated and very nicely plotted together given all the disparate threads it is working with.
I haven't read any of Bui's other work, but it looks like she's published a picture book for kids as well as a series of short comics during the pandemic. Besides Oseman who also writes non-illustrated fiction and the two manga artists Ice mentioned, Bui is the first graphic novel author I've included here, but I've actually got quite a few of them in my longer list, one of whom may make it into the 30 I'll include in this thread. These days I'm reading a bunch of graphic novels since they're easy to get through, and the variety of stories and perspectives in that space is wonderful these days, with a huge array of indie stuff that probably never would have gotten off the ground in traditional publishing/comics spaces.

The foundational value of quantum computing for classical fluids
Quantum algorithms for classical physics problems expose new patterns of quantum information flow as compared to the many-body Schrödinger equation. As a result, besides their potential practical applications, they also offer a valuable theoretical and computational framework to elucidate the foundations of quantum mechanics, particularly the validity of the many-body Schrödinger equation in the limit of large number of particles, on the order of the Avogadro number. This idea is illustrated …

Linear Algebra Problems Solved by Using Damped Dynamical Systems on the Stiefel Manifold
We develop a new method for solving minimization problems on the Stiefel Manifold using damped dynamical systems. The constraints are satisfied in the limit by an additional damped dynamical system. The method is illustrated by numerical experiments and compared to a state-of-the-art conjugate gradient method.

This work introduces two techniques for the design and analysis of branching algorithms, illustrated through the case study of the Vertex Cover problem. First, we present a method for automatically generating branching rules through a systematic case analysis of local structures. Second, we develop a new technique for analyzing randomized branching algorithms using the Measure & Conquer method, offering greater flexibility in formulating branching rules. By combining these innovations with addi…

Just finished "The Raven Boys," a graphic novel adaptation of a novel by Maggie Stiefvater (adaptation written by Stephanie Williams and illustrated by Sas Milledge).
I haven't read the original novel, and because of that, this version felt way too dense, having to fit huge amounts of important details into not enough pages. The illustrations are gorgeous and the writing is fine; the setting and plot have some pretty interesting aspects... It's just too hard to follow a lot of the threads, or things we're supposed to care about aren't given the time/space to feel important.
The other thing that I didn't like: one of the central characters is rich, and we see this reflected in several ways, but we're clearly expected to ignore/excuse the class differences within the cast because he's a good guy. At this point in my life, I'm simply no longer interested in stories about good rich guys very much. It's become clear to me how in real life, we constantly get the perspectives of the rich, and rarely if ever hear the perspectives of the poor (same applies across racial and gender gradients, among others). Why then in fiction should I get more of the same, spending my mental bandwidth building empathy for yet another dilettante who somehow has a heart of gold? I'm tired of that.

Non-perturbatively slow spread of quantum correlations in non-resonant systems
Strong disorder often has drastic consequences for quantum dynamics. This is best illustrated by the phenomenon of Anderson localization in non-interacting systems, where destructive quantum wave interference leads to the complete absence of particle and information transport over macroscopic distances. In this work, we investigate the extent to which strong disorder leads to provably slow dynamics in many-body quantum lattice models. We show that in any spatial dimension, strong disorder leads…

Multi-dimensional chaos I: Classical and quantum mechanics
We introduce the notion of multi-dimensional chaos that applies to processes described by erratic functions of several dynamical variables. We employ this concept in the interpretation of classical and quantum scattering off a pinball system. In the former case it is illustrated by means of two-dimensional plots of the scattering angle and of the number of bounces. We draw similar patterns for the quantum differential cross section for various geometries of the disks. We find that the eigenvalu…

Infinite-dimensional Lagrange-Dirac systems with boundary energy flow II: Field theories with bundle-valued forms

arXiv:2511.05687v1 Announce Type: new
Abstract: Part I of this paper introduced the infinite dimensional Lagrange--Dirac theory for physical systems on the space of differential forms over a smooth manifold with boundary. This approach is particularly well-suited for systems involving energy exchange through the boundary, as it is built upon a restricted dual space -a vector subspace of the topological dual of the configuration space- that captures information about both the interior dynamics and boundary interactions. Consequently, the resulting dynamical equations naturally incorporate boundary energy flow. In this second part, the theory is extended to encompass vector-bundle-valued differential forms and non-Abelian gauge theories. To account for two commonly used forms of energy flux and boundary power densities, we introduce two distinct but equivalent formulations of the restricted dual. The results are derived from both geometric and variational viewpoints and are illustrated through applications to matter and gauge field theories. The interaction between gauge and matter fields is also addressed, along with the associated boundary conditions, applied to the case of the Yang-Mills-Higgs equations.

Using Gauge Covariant Lie Derivatives in Einstein-Cartan and Metric Teleparallel Theories of Gravity
A procedure to determine the initial ansatz for the co-frame and spin connection characterizing a Riemann-Cartan geometry respecting a given group of continuous symmetries is illustrated. Given a particular group of symmetries and assuming an orthonormal gauge we can determine the co-frame and corresponding spin connection having this symmetry group by employing an gauge covariant Lie derivative. This gauge covariant Lie derivative when applied to the metric and co-frame determines the values o…

Multi state neurons

Abstract: Neurons, as eukaryotic cells, have powerful internal computation capabilities. One neuron can have many distinct states, and brains can use this capability. Processes of neuron growth and maintenance use chemical signalling between cell bodies and synapses, ferrying chemical messengers over microtubules and actin fibres within cells. These processes are computations which, while slower than neural electrical signalling, could allow any neuron to change its state over intervals of seconds or minutes. Based on its state, a single neuron can selectively de-activate some of its synapses, sculpting a dynamic neural net from the static neural connections of the brain. Without this dynamic selection, the static neural networks in brains are too amorphous and dilute to do the computations of neural cognitive models. The use of multi-state neurons in animal brains is illustrated in hierarchical Bayesian object recognition. Multi-state neurons may support a design which is more efficient than two-state neurons, and scales better as object complexity increases. Brains could have evolved to use multi-state neurons. Multi-state neurons could be used in artificial neural networks, to use a kind of non-Hebbian learning which is faster and more focused and controllable than traditional neural net learning. This possibility has not yet been explored in computational models.

This paper explores the extension of the classical two-parameter Weibull distribution to a four-parameter Harris extended Weibull (HEW) distribution. The flexibility of this probability distribution is illustrated by the varying shapes of HEW density function. Estimation of HEW parameters is explored using estimation methods such as the least-squares, maximum product of spacings, and minimum distance method. We provide Bayesian inference on the random parameters of the HEW distribution using Me…

The framework unifies convergence to points and sets and is illustrated through applications to inertial …

The effect of detector-related uncertainties on the determination of the parent particle mass in two-body decays is described.

The approach is illustrated for the case of measuring the $Λ$ hyperon mass.

It's a very cool graphic novel about the illusions of meritocracy and loyalty to one's roots, with an interesting setting and better politics than most stuff out there, even if the plotting is a little rough and perhaps a bit too straightforward. The neat ending and reliance on heroism are themes I don't love in these kinds of tales, but I'm grateful for more stories in this category to exist in the first place, so I can't complain too much.
It's got disability, queer, and POC representation and some of that is #OwnVoices, which is cool, although those dimensions of the work aren't its focus.

Algebraic quantisation approach to integrable differential-difference equations
We develop an algebraic quantisation approach, based on quantisation ideals, and apply it to integrable non-Abelian differential--difference equations. We show that the Toda hierarchy admits a bi-quantum structure whose classical (commutative) limit recovers a well-known Poisson pencil. In addition, we discover a non-standard quantisation that has no commutative counterpart. In both cases we present the quantum systems in the Heisenberg form. The generality of the method is illustrated throug…

Forecasting High Dimensional Time Series with Dynamic Dimension Reduction
Many dimension reduction techniques have been developed for independent data, and most have also been extended to time series. However, these methods often fail to account for the dynamic dependencies both within and across series. In this work, we propose a general framework for forecasting high-dimensional time series that integrates dynamic dimension reduction with regularization techniques. The effectiveness of the proposed approach is illustrated through a simulated example and a forecasti…

The results are then illustrated by showing that they apply to the Gamma and providing numerical simulations and an application to biological…

In this work, we investigate an extension of the former to general Banach spaces and provide worst-case convergence rates for, both, convex and nonconvex, problem instances. Moreover, assuming additional regularity properties of stationary points, linear rates of convergence are derived. The theoretical results are illustrated for bang-bang type optimal control problems with partial dif…
