Using Language and Road Manuals to Inform Map Reconstruction for Autonomous Driving
Lane-topology prediction is a critical component of safe and reliable autonomous navigation. An accurate understanding of the road environment aids this task. We observe that this information often follows conventions encoded in natural language, through design codes that reflect the road structure and road names that capture the road functionality. We augment this information in a lightweight manner to SMERF, a map-prior-based online lane-topology prediction model, by combining structured road…

Development of a laser stabilized on an ultra-stable silicon cryogenic Fabry-Perot cavity for dark matter detection
Astrophysical observations suggest the existence of an unknown kind of matter in the Universe, in the frame of the $Λ$CDM model. The research field of dark matter covers an energy scale going from massive objects to ultra-light scalar fields, which are the focus of the present work. It is supposed that ultra-light scalar fields affect the length of objects, whereas the speed of light stays unchanged. It follows that Fabry-Perot cavities are ideal tools for ultra-light dark matter detection sin…

Scaling Laws for Uncertainty in Deep Learning
Deep learning has recently revealed the existence of scaling laws, demonstrating that model performance follows predictable trends based on dataset and model sizes. Inspired by these findings and fascinating phenomena emerging in the over-parameterized regime, we examine a parallel direction: do similar scaling laws govern predictive uncertainties in deep learning? In identifiable parametric models, such scaling laws can be derived in a straightforward manner by treating model parameters in a B…

An Architecture for Privacy-Preserving Telemetry Scheme
We present a privacy-preserving telemetry aggregation scheme. Our underlying frequency estimation routine works within the framework of differential privacy. The design philosophy follows a client-server architecture. Furthermore, the system uses a local differential privacy scheme where data gets randomized on the client before submitting the request to the resource server. This scheme allows for data analysis on de-identified data by carefully adding noise to prevent re-identification attacks…

Brownian motion with stochastic energy renewals
We investigate the impact of intermittent energy injections on a Brownian particle, modeled as stochastic renewals of its kinetic energy to a fixed value. Between renewals, the particle follows standard underdamped Langevin dynamics. For energy renewals occurring at a constant rate, we find non-Boltzmannian energy distributions that undergo a shape transition driven by the competition between the velocity relaxation timescale and the renewal timescale. In the limit of rapid renewals, the dynami…

Define \[s^+(G)=\sum_{λ_i >0} λ_i^2(G), \quad s^-(G)=\sum_{λ_i<0} λ_i^2(G).\] It was conjectured by Elphick, Farber, Goldberg and Wocjan that for every connected graph $G$ of order $n$, $s^+(G) \ge n-1.$ We verify this conjecture for graphs with domination number at most 2. We then strengthen the conjecture as follows: if $G$ is a connected graph of order $n$ and size $m \geq n+1$, then $s^+(G) \geq n…

Each Lie algebra therefore endows any quantum state with a fixed "budget" of metrological sensitivity -- an intrinsic resource that we show, like optical squeezing in interfero…

Light deflection in unified gravity and measurable deviation from general relativity
Light does not travel in a perfectly straight line when it passes near massive objects. Instead, it follows the curvature of spacetime as predicted by general relativity. In this work, we apply the gauge theory of unified gravity [Rep. Prog. Phys. 88, 057802 (2025)], formulated as an extension of the Standard Model to include gravity. Using dynamical equations, we calculate gravitational deflection of light near astrophysical objects without need to use a curved metric. We do not use a single f…

Bounomodes: the grazing ox algorithm for exploration of clustered anomalies
A common class of algorithms for informative path planning (IPP) follows boustrophedon ("as the ox turns") patterns, which aim to achieve uniform area coverage. However, IPP is often applied in scenarios where anomalies, such as plant diseases, pollution, or hurricane damage, appear in clusters. In such cases, prioritizing the exploration of anomalous regions over uniform coverage is beneficial. This work introduces a class of algorithms referred to as bounomōdes ("as the ox grazes"), which al…

A simplified construction of the integer dimension Hausdorff measures is given applying methods of geometry and generalized convergence. This construction prioritizes integration, yields the Area Formula as a byproduct of the construction and the Coarea Formula follows indirectly from the smooth case. Though this construction is not as general as the traditional one, it provides a much simpler introduction to the topic and is enough for certain applications to Geometric Analysis.

Higher Kazhdan projections and delocalized $\ell^2$-Betti numbers for an amalgamated product group
We establish explicit expressions for the $K$-theory classes of higher Kazhdan projections for amalgamated product groups $\mathbb{Z}_m*_{\mathbb{Z}_d}\mathbb{Z}_n$. Our approach follows the methodology developed by Pooya and Wang for free product groups $\mathbb{Z}_m*\mathbb{Z}_n$, and naturally generalizes their results on free products. As an application of the $K$-class expressions, we obtain non-vanishing results for delocalized $\ell^2$-Betti numbers of $\mathrm{SL}(2,\mathbb{Z})$.

Computing in complete local equicharacteristic Noetherian rings via topological rewriting on commutative formal power series
In commutative algebra, the theory of Gröbner bases enables one to compute in any finitely generated algebra over a given computable field. For non-finitely generated algebras however, other methods have to be pursued. For instance, it follows from the Cohen structure theorem that standard bases of formal power series ideals offer a similar prospect but for complete local equicharacteristic rings whose residue field is computable. Using the language of rewriting theory, one can characterise Gr…

However, this phenomenon seems paradoxical given the diffusive and unpredictable price dynamics; (ii) the price impact $I(Q)$ of a large metaorder $Q$ follows the square-root law, $I(Q)\propto \sqrt{Q}$.

The blue crane, South Africa’s national bird, is now at greater risk of extinction, as a new regional assessment lists the species as “vulnerable.” “A Near-Threatened listing is no longer appropriate, now that the population is declining,” states the recently published Red Data Book of Birds, which follows the International Union for Conservation of Nature […]

Wow, Aston Villa got absolutely jobbed and it cost them a Champions League spot that is worth > £100 million. PGMOL is just so dreadfully incompetent.
Unai Emery follows the referees into the tunnel afterwards, berating them the entire way but it’s cool because he’s not the #LFC manager.

Mamdani follows in AOC’s footsteps,
having defeated an entrenched figure of the establishment with grassroots progressive support.
So this was a sweet moment.
Mamdani has received supportive words from both Senator Chuck Schumer…
And Governor Kathy Hochul…
Hopefully, formal endorsements are forthcoming.
An unintended, but hopeful consequence of Mamdani’s win is that, at 33 years old, he has inspired other young people to want to run for office themselves.…

On a Recursive Integer Sequence Implying the Nonexistence of Odd Perfect Numbers
We define a sequence of positive integers recursively, where each term is determined as follows: starting with a given positive integer, if the term is odd, the next is the sum of its positive divisors; if the term is even, the subsequent term is half the term. It is conjectured that the sequence eventually reaches one for all initial values. In this paper, we classify a family of integers for which this conjecture holds.

Divisibility classes of ultrafilters and their patterns
A divisibility relation on ultrafilters on the set $\mathbb{N}$ of natural numbers is defined as follows: ${\cal F}\hspace{1mm}\widetilde{\mid}\hspace{1mm}{\cal G}$ if and only if every set in $\cal F$ upward closed for divisibility also belongs to $\cal G$. Previously we isolated basic classes: powers of prime ultrafilters, and described the pattern of an ultrafilter, measuring the quantity of members of each basic class dividing a given ultrafilter. In this paper we define a topology on the s…

On closure properties of TotP
The class TotP consists of functions that count the number of all paths of a nondeterministic polynomial-time Turing machine. In this paper, we give a second definition of the class TotP in terms of certificates and verifiers, and present a few natural closure properties of this class. From the second definition of TotP it follows that TotP = #P if and only if P = NP. We also prove that the closure of TotP under left composition with the class FP+ is equivalent to TotP = FP+ and P = PP, and giv…

A Leptonic Interpretation of the UHE Gamma-ray Emission from V4641 Sgr

A Leptonic Interpretation of the UHE Gamma-ray Emission from V4641 Sgr
Recently, the microquasar V4641 Sgr and its surrounding is detected at TeV-PeV gamma-ray band. Interestingly, the spectrum follows a power-law function continuing up to 0.8 PeV as reported by LHAASO, and the morphology of the emission appears a puzzling elongated structure. In this work, we propose that the elongated UHE emission from V4641 Sgr could originate from the inverse Compton radiation of electrons with a very hard spectrum, which may result from shear acceleration mechanism in the jet…

A Casimir-like probe for 4D Einstein-Gauss-Bonnet gravity
Virtual transitions in a Casimir-like configuration are utilized to probe quantum aspects of four-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity. This study employs a quantum optics-based approach, wherein an Unruh-DeWitt detector (modeled as a two-level atom) follows a radial timelike geodesic, falling freely into an uncharged, nonrotating black hole described by 4D EGB gravity, becoming thermalized in the usual Unruh manner. The black hole, asymptotically Minkowskian, is enclosed by a Cas…

When Bi-interpretability implies Synonymy
Two salient notions of sameness of theories are synonymy, also known as definitional equivalence, and bi-interpretability. Of these two definitional equivalence is the strictest notion. In which cases can we infer synonymy from bi-interpretability? We study this question for the case of sequential theories. Our result is as follows. Suppose that two sequential theories are bi-interpretable and that the interpretations involved in the bi-interpretation are one-dimensional and identity preserving…

Pseudorandom bits for non-commutative programs
We obtain new explicit pseudorandom generators for several computational models involving groups. Our main results are as follows: 1. We consider read-once group-products over a finite group $G$, i.e., tests of the form $\prod_{i=1}^n g_i^{x_i}$ where $g_i\in G$, a special case of read-once permutation branching programs. We give generators with optimal seed length $c_G \log(n/\varepsilon)$ over any $p$-group. The proof uses the small-bias plus noise paradigm, but derandomizes the noise to av…

Senate Democrats are increasingly concerned that President Donald Trump is considering striking Iran without seeking authorization from Congress
— or even filling them in on his plans.

Sen. Tim Kaine (D-Virginia) is mounting a last-ditch push to force a vote as soon as next week
to restrain Trump from attacking Iran without Congress’s approval.

Other Senate Democrats say the White House has not briefed them on its plans for a potential strike.
And some are warn…
