Universal Rates of ERM for Agnostic Learning
The universal learning framework has been developed to obtain guarantees on the learning rates that hold for any fixed distribution, which can be much faster than the ones uniformly hold over all the distributions. Given that the Empirical Risk Minimization (ERM) principle being fundamental in the PAC theory and ubiquitous in practical machine learning, the recent work of arXiv:2412.02810 studied the universal rates of ERM for binary classification under the realizable setting.

Determining the chemical potential via universal density functional learning
We demonstrate that the machine learning of density functionals allows one to determine simultaneously the equilibrium chemical potential across simulation datasets of inhomogeneous classical fluids. Minimization of an implicit loss function based on an Euler-Lagrange equation yields both the universal one-body direct correlation functional, which is represented locally by a neural network, as well as the system-specific unknown chemical potential values. The method can serve as an efficient al…

A universal W-algebra for N=4 super Yang-Mills
Using bootstrap methods, we provide evidence for the existence of a non-linear W-algebra, denoted $W_\infty^\text{s,s}$, which contains the small N= 4 super Virasoro algebra and features an infinite tower of additional generators, organized in short supersymmetry multiplets. The algebra $W_\infty^\text{s,s}$ has one free parameter, its central charge c. We claim that the simple quotient of $W_\infty^\text{s,s}$ for c= -3(N^2-1) is isomorphic to the vertex operator algebra associated to 4d N=4 $…

An inverse monoid $M$ is called $F$-inverse if each $σ$-class of $M$, where $σ$ is the minimum group congruence of $M$, has a maximum element with respect to the natural order of $M$. Upon Kinyon's observation made in 2018 that $F$-inverse monoids form a variety in the enriched signature involving an additional unary operation mapping each element of $M$ to the maximum element of its $σ$-class, a separate theory of $F$-inverse monoids is developing in recent years, greatly aided by a recent …

Towards fault-tolerant quantum computation with universal continuous-variable gates
Continuous-variable (CV) systems have shown remarkable potential for quantum computation, particularly excelling in scalability and error correction through bosonic encoding. Within this framework, the foundational notion of computational universality was introduced in [Phys. Rev. Lett. 82, 1784 (1999)], and has proven especially successful since it allows for the identification of finite sets of universal CV gates independent of the encoding scheme. However, achieving the critical objective of…

On Universal Deformations of Compressible Cauchy Elastic Solids Reinforced by Inextensible Fibers
Universal deformations are those that can be maintained in the absence of body forces and by applying only boundary tractions, for all materials within a given constitutive class. We study the universal deformations of compressible isotropic Cauchy elastic solids reinforced by a single family of inextensible fibers. We consider straight fibers parallel to the Cartesian Z-axis in the reference configuration and derive the universality constraints. The principal invariants of the right Cauchy-Gre…

Isometric-Universal Graphs for Trees
We consider the problem of finding the smallest graph that contains two input trees each with at most $n$ vertices preserving their distances. In other words, we look for an isometric-universal graph with the minimum number of vertices for two given trees. We prove that this problem can be solved in time $O(n^{5/2}\log{n})$. We extend this result to forests instead of trees, and propose an algorithm with running time $O(n^{7/2}\log{n})$. As a key ingredient, we show that a smallest isometric-un…

We solve the $K$-theoretically refined Donaldson-Thomas theory of local curves. Our results avoid degeneration techniques, but rather exploit direct localisation methods to reduce the refined Donaldson-Thomas partition function to the equivariant intersection theory of skew nested Hilbert schemes on smooth projective curves. We show that the latter is determined, for every Young diagram, by three universal series, which we compute in terms of the 1-leg $K$-theoretic equivariant vertex. In the r…

Universal Relation between Spectral and Wavefunction Properties at Criticality
Quantum-chaotic systems exhibit several universal properties, ranging from level repulsion in the energy spectrum to wavefunction delocalization. On the other hand, if wavefunctions are localized, the levels exhibit no level repulsion and their statistics is Poisson. At the boundary between quantum chaos and localization, however, one observes critical behavior, not complying with any of those characteristics. An outstanding open question is whether there exist yet another type of universality,…

We show that rotating viscous stars amplify incoming low-frequency gravitational waves, a phenomenon which we argue to be universal. Superradiant amplification does not seem …

Proof of a conjecture on isolation of graphs with a universal vertex
A copy of a graph $F$ is called an $F$-copy. For any graph $G$, the $F$-isolation number of $G$, denoted by $ι(G,F)$, is the size of a smallest subset $D$ of the vertex set of $G$ such that the closed neighbourhood $N[D]$ of $D$ in $G$ intersects the vertex sets of the $F$-copies contained by $G$ (equivalently, $G-N[D]$ contains no $F$-copy). Thus, $ι(G,K_1)$ is the domination number $γ(G)$ of $G$, and $ι(G,K_2)$ is the vertex-edge domination number of $G$. Settling a conjecture of Zhang an…

As modeling urban sprawl remains an open problem, these results offer a necessary empirical basis for theory.

Charge Pickup Reaction Cross Section for Neutron-Rich p-Shell Isotopes at 900A MeV
We report charge pickup reaction cross sections for 24 \textit{p}-shell isotopes, including $^{8,9}$Li, $^{10-12}$Be, $^{10,13-15}$B, $^{12,14-19}$C and $^{14,15,17-22}$N, measured at relativistic energies (approximately 900$A$ MeV) on both hydrogen and carbon targets. For the first time, we reveal a universal rapid increase in the charge pickup cross sections of unstable projectiles with isospin asymmetry along several isotopic chains.

Pegasus: A Universal Framework for Scalable Deep Learning Inference on the Dataplane
The paradigm of Intelligent DataPlane (IDP) embeds deep learning (DL) models on the network dataplane to enable intelligent traffic analysis at line-speed. However, the current use of the match-action table (MAT) abstraction on the dataplane is misaligned with DL inference, leading to several key limitations, including accuracy degradation, limited scale, and lack of generality. This paper proposes Pegasus to address these limitations. Pegasus translates DL operations into three dataplane-orien…

Calamus 29 One flitting glimpse
What a sweet poem of quiet love. One of my favorites so far.
The setup is voyeuristic: we're spying on a bar full of men. And we see Whitman in a corner, and then
a youth who loves me, and whom I love, silently approaching, and seating himself near, that he may hold me by the hand
It astonishes me that these poems of clear homosexual love were published in 1860!
What's particularly nice is the contrast between the rowdy bar scene
drinking and oath and smutty jest
and the quiet intimacy of Whitman and his lover
we two, content, happy in being together, speaking little, perhaps not a word.
The expression of love here is universal. But it is a man writing about a man, in the company of men. And thus it is particularly mine.

Collisionless relaxation to quasi-steady state attractors in cold dark matter halos: origin of the universal NFW profile
Collisionless self-gravitating systems such as cold dark matter halos are known to harbor universal density profiles despite the intricate non-linear physics of hierarchical structure formation in the $Λ$CDM paradigm. The origin of these attractor states has been a persistent mystery, particularly because the physics of collisionless relaxation is not well understood. To solve this long-standing problem, we develop a self-consistent quasilinear theory in action-angle space for the collisionles…

Quasiparticle Properties of Long-Range Impurities in a Bose Condensate
An impurity immersed in a Bose condensate can form a quasiparticle known as a Bose polaron. When the impurity-boson interaction is short-ranged, the quasiparticle's properties are universal, characterized - independent of the bath density $n_0$ - by the impurity-boson scattering length $a_{IB}$. Long-ranged interactions - such as provided by Rydberg or ionic impurities - introduce an effective interaction range $r_{\mathrm{eff}}$, and boson-boson interactions provide a third length scale, the c…

The scalar may be produced at the LHC in association with a $Z'$ boson, or through $Z'$ boson fusion, while its de…

Complete universal scaling of first-order phase transitions in the two-dimensional Ising model
Phase transitions, as one of the most intriguing phenomena in nature, are divided into first-order phase transitions (FOPTs) and continuous ones in current classification. While the latter shows striking phenomena of scaling and universality, the former has recently also been demonstrated to exhibit scaling and universal behavior within a mesoscopic, coarse-grained Landau-Ginzburg theory. Here we apply this theory to a microscopic model -- the paradigmatic Ising model, which undergoes FOPTs bet…

Recently, it was shown that for quantum processes governed by Markovian semigroups, the relaxation rates satisfy a universal constraint: the maximal rate is upper-bounded by the sum of all rat…
