The 1st Solution for MOSEv2 Challenge 2025: Long-term and Concept-aware Video Segmentation via SeC
This technical report explores the MOSEv2 track of the LSVOS Challenge, which targets complex semi-supervised video object segmentation. By analysing and adapting SeC, an enhanced SAM-2 framework, we conduct a detailed study of its long-term memory and concept-aware memory, showing that long-term memory preserves temporal continuity under occlusion and reappearance, while concept-aware memory supplies semantic priors that suppress distractors; together, these traits directly benefit several MOS…

Collins-type fragmentation energy correlator in semi-inclusive deep inelastic lepton-hadron scattering
We initiate a systematic study of fragmentation energy correlators (FECs), which generalize traditional fragmentation functions and encode non-perturbative information about transverse dynamics in parton fragmentation processes. We define boost-invariant, non-perturbative FECs and derive a corresponding collinear factorization formula. A spin decomposition of the FECs is carried out, analogous to that of transverse-momentum-dependent fragmentation functions. In this work we focus particularly o…

On the Weyl function for complex Jacobi matrices
We derive a new representation for the Weyl function associated with the complex Jacobi matrix in the finite and semi-infinite cases. In our approach we exploit connections to the discrete-time dynamical system associated with these matrices.

So in another dream I just woke up from, I was talking to someone about "the idea problem" (that it's becoming harder to monitize ideas, from a vox article written by an AI cooked reporter).
https://www.iheart.com/podcast/105-it-could-happen-here-30717896/episode/executive-disorder-white-house-weekly-46-313675864/
Basically, I was arguing that the majority of inventions target men because patriarchy puts economic control in men's hands. As men have started to help more with childcare, there have been more inventions related to childcare. (I don't have any idea if this is true. Seems legit, but I'm just relating my dream. I think I was also oversimplifying a bit to "men" and "women" because of my audience, but anyway it was a dream.) There's actually more low-hanging fruit, I pointed out, related to making care work easier.
So I argued that the real problem was a failure to invest in research into solving that problem. Today there are all these boondoggles built around killing people. What if, instead of all this government research into killing people, we dumped a ton of money into making it easier to support a household? That would be great for the economy. (Being asleep, I seem to have forgotten that working people need money.)
In the blur of being just awake I started thinking about how you could kickstart the US economy by taking the money from the AI boondoggle and other autonomous murder bots and create something like a program to build robots for housekeepers. You'd still be funding tech with government money, so the same horrible people get paid, but you're now actually solving real problems. It wouldn't even matter if it was a boondoggle, honestly. Just dumping money into something other than murdering people is good enough.
I imagined first if there was a program to fund a robot housecleaner, like robot dog with AI some laundry pickup, that would be provided, free of charge, to help people with children. It would work the same as the military boondoggle where a private company makes the government buy a piece of hardware from them and then also pay them to service it for some number of years. But instead of that hardware sitting around waiting to kill someone, it would be getting brought to people's houses to help them.
Then I thought, hey, you could even boost the economy more if you just had government funding for doulas and housecleaners and paid them a living wage. Hey, you could really kickstart the economy by nationalizing healthcare and including doula support as part of all births. Oh, and you could also just include the optional household help for families with children until the kids turn 18.
None of this is perfect (I don't actually think most of this is possible from any state), but the point is that it's actually wildly easy to figure out all kinds of ways to invest in the economy and monitize ideas as long as you aren't entirely focused on the same old "make money from spying on people and killing them." Funny that. Like they said in the podcast, maybe "finding ideas" isn't the problem.
Hope you enjoyed the weird semi-awake brain dump/rant.

But here’s the thing: if you spray paint the top of your loaf with a lovely layer of golden brown paint, that doesn’t mean the loaf is now fully baked! You have to actually •do the work• until you see that perfect golden brown.
As I read it, the much-cited 3.5% figure from that study is •not• the thing that magically stops the authoritarian slide. It is an •indicator• that all of the important but semi-invisible things that can topple an authoritarian are actually happening.

$0.50 per mile for electricity for a semi truck? wow, lower than I would imagine. (and it can be as low as $0.12 where rates are lower.).
"During testing, the truck averaged 1.72 kWh per mile while hauling a gross combined weight of 75,000 pounds (34 metric tons) over a 390-mile (625 km) long-haul route."
a tesla model 3 is ~0.3 kWh per mile.

There’s this place we walk by pretty regularly that’s semi-abandoned. The owner replaces parts when they fall off and there are lights at night, but the front and back have been left to return to nature. This chunk of land is worth ~$2.5M Canadian, so an odd situation. Anyhow, I enjoy watching the progress of the informal small-scale rewilding.

ProtoSiTex: Learning Semi-Interpretable Prototypes for Multi-label Text Classification
The surge in user-generated reviews has amplified the need for interpretable models that can provide fine-grained insights.

We propose ProtoSiTex, a semi-interpretable framework designed for fine-grained multi-label text classification. ProtoSiTex employs a dual-phase alternating traini…

Semi-parametric Markov models for multi-type point patterns
Multi-type Markov point processes offer a flexible framework for modelling complex multi-type point patterns where it is pertinent to capture both interactions between points as well as large scale trends depending on observed covariates. However, estimation of interaction and covariate effects may be seriously biased in the presence of unobserved spatial confounders. In this paper we introduce a new class of semi-parametric Markov point processes that adjusts for spatial confounding through a …

Day 19 (a bit late): Alice Oseman
As I said I've got 14 authors to fit into two days. Probably just going to extend to 30? But Oseman gets this spot as an absolute legend of queer fiction in both novel & graphic novel form, and an excellent example of the many truths queer writers have to share with non-queer people that can make everyone's lives better. Her writing is very kind, despite in many instances dealing with some dark stuff.
I started out on Heartstopper, which is just so lovely and fun to read, and then made my way through several of her novels. The one I'll highlight here which I think it's her greatest triumph is "Loveless", which is semi-autobiographical and was at least my first (but no longer only) experience with the "platonic romance" sub-genre. It not only helped me work through some crufty internal doubts about aro/ace identities that I'd never really examined, but in the process helped improve my understanding of friendship, period. Heck, it's probably a nice novel for anyone questioning any sort of identity or dealing with loneliness, and it's just super-enjoyable as a story regardless of the philosophical value.
To cheat a bit more here on my author count, I recently read "Dear Wendy" by Ann Zhao, which shouts out "Loveless" and offers a more expository exploration of aro/ace identities, but "Loveless" is a book with more heart and better writing overall, including the neat plotting and great pacing. I think there are also parallels with Becky Albertalli's work, though I think I like Oseman slightly more. Certainly both excel at writing queer romance (and romance-adjacent) stuff with happy endings (#OwnVoices wins again with all three authors).
In any case, Oseman is excellent and if you're not up for reading a novel, Heartstopper is a graphic novel series that's easy to jump into and very kind to its adorable main characters.
I think I've now decided to continue to 30, which is a relief, so I'm tagging this (and the next post that rounds out 20) two ways.

Having the ability to answer motion-planning queries within a fixed time budget is critical for the widespread deployment of robotic systems.

However, prior approaches in this setting either lack formal guarantees or rely on restrictive discretizations o…

A semi-symmetric metric connection, perfect fluid space-time and phantom barrier
We consider a concircularly semi-symmetric metric connection and its application. The Ricci tensors with respect to the concircularly semi-symmetric metric connection are symmetric, and they are used to define Einstein type manifolds. In this way, conditions under which a pseudo-Riemannian manifold is quasi-Einstein are obtained. On a Lorentzian manifold, a concircularly semi-symmetric metric connection with a unit timelike generator becomes a semi-symmetric metric $P$-connection, and a Lorentz…

These conditions will be presented in terms of dimension and degree of the hypersurfaces, dimension of the singular locus and multiplicities of the singular points. When singularities of the hypersurface are isolated and all have multiplicity 2, we can judge its stability via the ranks of Hessian matrices at these singular points.

Interpretable Generative and Discriminative Learning for Multimodal and Incomplete Clinical Data
Real-world clinical problems are often characterized by multimodal data, usually associated with incomplete views and limited sample sizes in their cohorts, posing significant limitations for machine learning algorithms. In this work, we propose a Bayesian approach designed to efficiently handle these challenges while providing interpretable solutions. Our approach integrates (1) a generative formulation to capture cross-view relationships with a semi-supervised strategy, and (2) a discriminati…

New Insights into Involutory and Orthogonal MDS Matrices
MDS matrices play a critical role in the design of diffusion layers for block ciphers and hash functions due to their optimal branch number. Involutory and orthogonal MDS matrices offer additional benefits by allowing identical or nearly identical circuitry for both encryption and decryption, leading to equivalent implementation costs for both processes. These properties have been further generalized through the notions of semi-involutory and semi-orthogonal matrices. Specifically, we establish…

Interband optical conductivity in two-dimensional semi-Dirac bands tilting along the quadratic dispersion
Two-dimensional (2D) semi-Dirac materials feature a unique anisotropic band structure characterized by quadratic dispersion along one spatial direction and linear dispersion along the other, effectively hybridizing ordinary and Dirac fermions. The anisotropy of energy dispersion can be further modulated through band tilting along either spatial direction of the wave vector. We propose a new definition of tilt parameter to characterize Lifshitz phases in 2D semi-Dirac bands tilting along the qua…

Semi-Rings, Semi-Vector Spaces, and Fractal Interpolation
In this paper, we introduce fractal interpolation on complete semi-vector spaces. This approach is motivated by the requirements of preservation of positivity or monotonicity of functions for some models in approximation and interpolation theory. The setting in complete semi-vector spaces does not requite additional assumptions but is intrinsically built into the frame work. For the purposes of this paper, fractal interpolation in the complete semi-vector spaces $C^+$ and $L_p^+$ is considered.

Bridged Clustering for Representation Learning: Semi-Supervised Sparse Bridging
We introduce Bridged Clustering, a semi-supervised framework to learn predictors from any unpaired input $X$ and output $Y$ dataset. Our method first clusters $X$ and $Y$ independently, then learns a sparse, interpretable bridge between clusters using only a few paired examples. At inference, a new input $x$ is assigned to its nearest input cluster, and the centroid of the linked output cluster is returned as the prediction $\hat{y}$. Unlike traditional SSL, Bridged Clustering explicitly levera…

The problem of proximity in $R^3$ is reduced to the same in $R^2$, which is not found in the literature. A new method to solve the problem in $R^2$ is used based on the geometrical properties of the conics, such as sub-normal, length of the semi-major axis, eccentricity, slope and radius. Furthermore, the problem in $R^2$ is ca…

An inexact semismooth Newton-Krylov method for semilinear elliptic optimal control problem

arXiv:2511.10058v1 Announce Type: new
Abstract: An inexact semismooth Newton method has been proposed for solving semi-linear elliptic optimal control problems in this paper. This method incorporates the generalized minimal residual (GMRES) method, a type of Krylov subspace method, to solve the Newton equations and utilizes nonmonotonic line search to adjust the iteration step size. The original problem is reformulated into a nonlinear equation through variational inequality principles and discretized using a second-order finite difference scheme. By leveraging slanting differentiability, the algorithm constructs semismooth Newton directions and employs GMRES method to inexactly solve the Newton equations, significantly reducing computational overhead. A dynamic nonmonotonic line search strategy is introduced to adjust stepsizes adaptively, ensuring global convergence while overcoming local stagnation. Theoretical analysis demonstrates that the algorithm achieves superlinear convergence near optimal solutions when the residual control parameter $\eta_k$ approaches to 0. Numerical experiments validate the method's accuracy and efficiency in solving semilinear elliptic optimal control problems, corroborating theoretical insights.
