As releases slow down, it's time to think about what we got this year and where we are going. o3's search, agent vs model progress, and scaling's settling.

Slow Fluid Antenna Multiple Access with Multiport Receivers
We investigate whether equipping fluid-antenna (FA) receivers with multiple ($L>1$) radiofrequency (RF) chains can improve the performance of the slow fluid-antenna multiple access (FAMA) technique, which enables open-loop connectivity with channel state information (CSI) available only at the receiver side. We analyze the case of slow-FAMA users equipped with multiport receivers, so that $L$ ports of the FA are selected and combined to reduce interference. We show that a joint design of the po…

Slow Light Augmented Fabry-Perot Cavity for Enhanced Sensitivity in Measuring Frequency Shift
Recently, it has been shown that a slow-light augmented unbalanced Mach-Zehnder interferometer (SLAUMZI) can be used to enhance significantly the sensitivity of measuring the frequency shift of a laser, compared to the conventional technique of heterodyning with a reference laser. Here, we show that a similar enhancement can be realized using a slow-light augmented Fabry-Perot Cavity (SLAFPC), due to the fact that an FPC is inherently unbalanced, since different bounces of the field traverse di…

Averaging principles for time-inhomogeneous multi-scale SDEs with partially dissipative coefficients
In this paper, we study averaging principles for a class of time-inhomogeneous stochastic differential equations (SDEs) with slow and fast time-scales, where the drift term in the fast component is time-dependent and only partially dissipative. Under asymptotic assumptions on the coefficients, we prove that the slow component $(X^{\varepsilon}_t)_{t\geq 0}$ converges strongly to the unique solution $(\bar{X}_t)_{t\geq 0}$ to an averaged SDE, when the diffusion coefficient in the slow component …

Topological slow entropy, sequence entropy, and generalized $[T,T^{-1}]$ systems
We consider topological dynamical systems given by skew products $S\rtimes_τ T$, where $S\colon Y\to Y$ is a subshift, $τ\colon Y\to\mathbb{Z}$ is a continuous cocycle, and $T$ is an arbitrary invertible topological system. For fixed $(Y,S,τ)$ it may happen that all systems of the form $S\rtimes_τT$ have the same topological entropy, and thus it arises the problem of distinguishing two such systems. We show that if $T_1$ and $T_2$ are invertible topological dynamical systems with differen…

Interesting thing about tomorrow's tarot show, rendering now, is that I upgraded from Blender 4.0 to blender 4.4 and it's quite a bit nicer to look at the timeline editor.
Was sad to find that the render time was up though. From about 3 seconds per frame usually to more like 12!?
Trying it with an old version I see that the lights and textures look way better with 4.4 than 4.0 though. A substantial step up in the way the show looks without me even doing anything other than waiting four times longer per frame.
Seems to be heavily dependent upon lighting now. The slow frames are like 12 seconds but the fast frames with minimal lighting and close up on the video are more like 2.
Looks too beautiful now to go back though. Upgraded my cloud-remote render machines too. We will render on four machines tonight. FOUR! The power of it all.
g3.4xlarge is no faster than g3.large but g6.xlarge seems to be twice the speed.
But hard to be sure really coz of the massive variance in time depending on the lighting.
Anyway, great show coming tomorrow. Sometimes I wonder what the hell I'm trying to do with it but tomorrow's show is the answer. Hide the angry bitter political rant behind a strange CGI tarot show. When the rant comes together well I like it.

ReDi: Rectified Discrete Flow
Discrete Flow-based Models (DFMs) are powerful generative models for high-quality discrete data but typically suffer from slow sampling speeds due to their reliance on iterative decoding processes. This reliance on a multi-step process originates from the factorization approximation of DFMs, which is necessary for handling high-dimensional data. In this paper, we rigorously characterize the approximation error from factorization using Conditional Total Correlation (TC), which depends on the cou…

We propose that these latent thoughts can be modeled as temporally-extended abstract actions, or options, with…

To overcome these limitations, we propose a Latent Noise Injection method using Masked Autoregressive F…

We demonstrate that the Chapman--Enskog series is locally equivalent to the exact spectral closure defined on slow kinetic eigenmodes in the limit of vanishing Knudsen number. We further show that the Chapman--Enskog series diverges everywhere expect at the global equilibrium for an explicit example, while the exact spectrally closed hydrodynamics are defined globally for any Knudsen number.

I also made a mode where it makes random changes to your “filesystem”. If you set the probability high enough, this is effectively a “forever” mode.

The analysis is validated with a spatial model. Finally, relaxing the timescale separation between reactions and di…

Abstract: We propose a scheme to transfer molecules from a slow beam into an optical trap using only a single photon absorption and emission cycle. The efficiency of such a scheme is numerically explored for BaF using realistic experimental parameters. The technique makes use of the state-dependent potential in an external electric field to trap molecules from an initial velocity of order 10m/s. A rapid optical transition at the point where the molecules come to a standstill in the electric field potential irreversibly transfers them into a ~7mK optical dipole trap. For a pulsed Stark decelerated beam, we estimated the per-shot efficiency to be ~0.04% or up to ~103 molecules, with a potential factor 20 improvement when the fields are synchronously modulated with the arriving velocity components. The irreversibility of the scheme allows for larger numbers to be built up over time. Since this scheme does not rely on a closed cycling transition for laser cooling, it broadens the range of molecules that can be used for research on cold molecular chemistry, quantum information, and fundamental interactions in optical traps.

Assessment of Power System Stability Considering Multiple Time-Scale Dynamics: Insights into Hopf Bifurcations in Presence of GFL and GFM IBRs
Real power systems exhibit dynamics that evolve across a wide range of time scales, from very fast to very slow phenomena. Historically, incorporating these wide-ranging dynamics into a single model has been impractical. As a result, power engineers rely on time-scale decomposition to simplify models. When fast phenomena are evaluated, slow dynamics are neglected (assumed stable), and vice versa. This paper challenges this paradigm by showing the importance of assessing power system stability w…

I Made A Real-Time C/C++/Rust Build Visualizer
Many software projects take a long time to compile. Sometimes that’s just due to the sheer amount of code, like in the LLVM project. But often a build is slower than it should be for dumb, fixable reasons. I’ve had the suspicion that most builds are doing dumb stuff, but I had no way to see it. So I’ve been working on a cross-platform tool to help speed up builds (you can try it, see below).

VLM-UDMC: VLM-Enhanced Unified Decision-Making and Motion Control for Urban Autonomous Driving
Scene understanding and risk-aware attentions are crucial for human drivers to make safe and effective driving decisions. To imitate this cognitive ability in urban autonomous driving while ensuring the transparency and interpretability, we propose a vision-language model (VLM)-enhanced unified decision-making and motion control framework, named VLM-UDMC. This framework incorporates scene reasoning and risk-aware insights into an upper-level slow system, which dynamically reconfigures the optim…

Canard cycles of non-linearly regularized piecewise smooth vector fields
The main purpose of this paper is to study limit cycles in non-linear regularizations of planar piecewise smooth systems with fold points (or more degenerate tangency points) and crossing regions. We deal with a slow fast Hopf point after non-linear regularization and blow-up. We give a simple criterion for upper bounds and the existence of limit cycles of canard type, expressed in terms of zeros of the slow divergence integral. Using the criterion we can construct a quadratic regularization of…

Betelgeuse, the Prototypical Red Supergiant
The behavior of the bright red supergiant, Betelgeuse, is described with results principally from the past 6 years. The review includes imaging, photometry, and spectroscopy to record the Great Dimming of 2019--2020. This event was followed by a slow ongoing recovery from the massive surface mass ejection after which the stellar characteristics changed. Theoretical simulations address the cause of this episodic mass ejection and the optical Dimming. Recent publications evaluating the perplexing…

Greed is slow on sparse graphs of oriented valued constraints
Greedy local search is especially popular for solving valued constraint satisfaction problems (VCSPs). Since any method will be slow for some VCSPs, we ask: what is the simplest VCSP on which greedy local search is slow? We construct a VCSP on 6n Boolean variables for which greedy local search takes 7(2^n - 1) steps to find the unique peak. Our VCSP is simple in two ways. First, it is very sparse: its constraint graph has pathwidth 2 and maximum degree 3. This is the simplest VCSP on which some…

A massive, evolved slow-rotating galaxy in the early Universe
In today's Universe, most galaxies are rotationally supported against gravity. However, a small fraction of the most massive galaxies which are no longer forming stars (i.e., they are quiescent) are dispersion supported, and are termed 'slow-rotators.' These galaxies, which are highly evolved and often exist in dense cluster environments, are theorized to be formed by a history of merger activity that on average decreases the angular momentum of the merged system and disturbs any disk structure…

Modulated Poisson-Dirichlet diffusions arising from inclusion processes with a slow phase
We study mean-field inclusion processes with an additional slow phase, in which particle interactions occur at a vanishing rate proportional to the inverse system size. In the thermodynamic limit, such systems exhibit condensation at high particle density, forming clusters of diverging size. Our main result provides convergence in law of inclusion processes to a novel two-component infinite-dimensional stochastic diffusion, describing the co-evolution of the solid condensed and microscopic flui…

Inflation from a generalized exponential plateau: towards extra suppressed tensor-to-scalar ratios
We investigate a standard minimally-coupled scalar-field inflationary scenario, which is based on a new potential, with suitably generalized plateau features, that leads to extra small tensor-to-scalar ratios. In particular, we consider a specific three-parameter potential, which has a flatter plateau and a steeper well compared to the Starobinsky potential in the Einstein frame. We study the inflationary realization and we show that it guarantees a prolonged period of slow-roll inflation and a…

Hydrodynamic Equations for Active Brownian Particles in the High Persistence Regime
Based on a recently proposed kinetic description of non-inertial active Brownian particles, Navier--Stokes-like equations are derived in the high persistence regime, where polarization is a slow field together with density. Using the Chapman--Enskog method, all transport coefficients in the equations are obtained in terms of microscopic quantities. A linear stability analysis of the homogeneous and isotropic state shows the appearance of a density instability, allowing us to determine the regio…

Inflationary Slow-Roll Parameters in the Jordan Frame for Cosmological F(R) Gravity Models
$F(R)$ inflationary models are analyzed without the Weyl transformation to the Einstein frame. Sufficient conditions for existence of global inflationary attractors in $F(R)$ models are provided. Following that, the procedure for calculating inflationary observables completely in the original, Jordan, frame is given. The described procedure is used to analyze a new $F(R)$ inflationary model (a one-parameter deformation of the Starobinsky model), which is shown to provide predictions in good agr…

Pseudocriticality in antiferromagnetic spin chains
Weak first-order pseudocriticality with approximate scale invariance has been observed in a variety of settings, including the intriguing case of deconfined criticality in 2+1 dimensions. Recently, this has been interpreted as extremely slow flows ("walking behavior") for real-valued couplings in proximity to a bona fide critical point with complex-valued couplings, described by a complex conformal field theory (CFT). Here we study an SU($N$) generalization of the the Heisenberg antiferromagnet…

Oscillations in a Slow-Fast Paleoclimate Model for Glacial Cycles
This paper investigates a deterministic variant of the Saltzman-Maasch model for Pleistocene glacial cycles, formulated as a three-dimensional dynamical system with cubic feedback in the atmospheric carbon dioxide equation. After reducing the model to a planar system on a critical manifold, we perform a detailed bifurcation analysis and identify both Hopf and Bautin (generalized Hopf) bifurcations, which govern the emergence of stable and unstable limit cycles. To analyze global transitions, we…

Successive Halving with Learning Curve Prediction via Latent Kronecker Gaussian Processes
Successive Halving is a popular algorithm for hyperparameter optimization which allocates exponentially more resources to promising candidates. However, the algorithm typically relies on intermediate performance values to make resource allocation decisions, which can cause it to prematurely prune slow starters that would eventually become the best candidate. We investigate whether guiding Successive Halving with learning curve predictions based on Latent Kronecker Gaussian Processes can overcom…

However, modern biomedical data coming with high dimensions make it challenging to perform the model estimation in traditional cluster analysis. The incorporation of factor analyzer into the mixture model provides a way to characterize the large set of data features, but the current estimation method is computationally impractical for massive data due to the intrinsic slow convergence of the embedded alg…

Learning, fast and slow: a two-fold algorithm for data-based model adaptation
This article addresses the challenge of adapting data-based models over time. We propose a novel two-fold modelling architecture designed to correct plant-model mismatch caused by two types of uncertainty. Out-of-domain uncertainty arises when the system operates under conditions not represented in the initial training dataset, while in-domain uncertainty results from real-world variability and flaws in the model structure or training process. To handle out-of-domain uncertainty, a slow learnin…

Much of the carbonaceous dust observed in the early universe may originate from colliding wind binaries (CWBs) hosting hot, luminous Wolf-Rayet (WR) stars. Downstream of the shock between the stellar winds there exists a suitable environment for dust grain formation, and the orbital motion of the stars wraps this dust into richly structured spiral geometries. The Apep system is the most extreme WR-CWB in our Milky Way: two WR stars produce a complex spiral dust nebula, whose slow expansion has …
