A numerical stabilization scheme for the shallow shelf approximation
We present the Thickness Stabilization Scheme (TSS), a numerical stabilization scheme suitable for the Shallow Shelf Approximation (SSA), one of the most widely-used models for large-scale Antarctic and Greenland ice sheet simulations. The TSS is constructed by inserting an adapted, explicit Euler thickness evolution equation into the driving stress term, thereby treating the term implicitly. We investigate the applicability of TSS across low- and high-shear idealized scenarios, by altering the…

An explicit splitting SAV scheme for the kinetic Langevin dynamics
The kinetic Langevin dynamics finds diverse applications in various disciplines such as molecular dynamics and Hamiltonian Monte Carlo sampling. In this paper, a novel splitting scalar auxiliary variable (SSAV) scheme is proposed for the dynamics, where the gradient of the potential $U$ is possibly non-globally Lipschitz continuous with superlinear growth. As an explicit scheme, the SSAV method is efficient, robust and is able to reproduce the energy structure of the original dynamics. By an en…

Coherent phase control of two-color continuous variable entangled light
A continuous variable Einstein-Podolsky-Rosen (EPR) state is a resource for secure quantum communication and distributed quantum sensing. Here we present a technique for coherent control of the two-color EPR state generated by a frequency nondegenerate optical parametric oscillator. The scheme allows for robust control of the homodyne detection of each of the two EPR quantum fields separated by 200 nanometers. We apply our control scheme to stabilize and characterize a strong entangled state of…

Power corrections to the production of a prompt photon in association with a jet in the $N$-jettiness slicing scheme at NLO QCD
We compute the next-to-leading-power corrections in the $N$-jettiness variable to the production of a prompt photon and a jet at next-to-leading order in perturbative QCD in the $q \bar q$ annihilation channel. We employ the $k_\perp$ jet algorithm and assume that the $N$-jettiness value divided by the jet transverse momentum is the smallest parameter in the problem; in particular it should be small compared to the jet radius $R$.

The Iarrobino scheme: a self-dual analogue of the Hilbert scheme of points
For a fixed quasi-projective scheme $X$ we introduce a self-dual analogue of ${\mathrm{Hilb}}_d(X)$ which we call the Iarrobino scheme of $X$. It is a fine moduli space of oriented Gorenstein zero-dimensional subschemes of $X$ together with some additional data (a self-dual filtration) which is vacuous over a big open set but non-trivial over the compactification. Via the link between Hilbert schemes and varieties of commuting matrices, Iarrobino schemes correspond to commuting symmetric matric…

A Unified Deep Reinforcement Learning Approach for Close Enough Traveling Salesman Problem
In recent years, deep reinforcement learning (DRL) has gained traction for solving the NP-hard traveling salesman problem (TSP). However, limited attention has been given to the close-enough TSP (CETSP), primarily due to the challenge introduced by its neighborhood-based visitation criterion, wherein a node is considered visited if the agent enters a compact neighborhood around it. In this work, we formulate a Markov decision process (MDP) for CETSP using a discretization scheme and propose a n…

Hybrid pipe dreams for the lower-upper scheme
In [KU23] were introduced hybrid pipe dreams interpolating between classic and bumpless pipe dreams, each hybridization giving a different formula for double Schubert polynomials. A bijective proof was given (following [GH23]) of the independence of hybridization, but only for nonequivariant Schubert polynomials. In this paper we further generalize to hybrid generic pipe dreams, replacing the bijective proof of hybridization-independence with a Yang-Baxter-based proof that allows one to maintai…

Starting from the derivation of the equipartition formula, we find…

A Monoid Ring Approach to Color Visual Cryptography
A visual cryptography scheme is a secret sharing scheme in which the secret information is an image and the shares are printed on transparencies, so that the secret image can be recovered by simply stacking the shares on top of each other. Such schemes do therefore not require any knowledge of cryptography tools to recover the secret, and they have widespread applications, for example, when sharing QR codes or medical images. In this work we deal with visual cryptography threshold schemes for c…

To corroborate the controllable generation, relevant to ultracold atom experiments, of these rogue patterns we e…

Designing Inferable Signaling Schemes for Bayesian Persuasion
In Bayesian persuasion, an informed sender, who observes a state, commits to a randomized signaling scheme that guides a self-interested receiver's actions. Classical models assume the receiver knows the commitment. We, instead, study the setting where the receiver infers the scheme from repeated interactions. We bound the sender's performance loss relative to the known-commitment case by a term that grows with the signal space size and shrinks as the receiver's optimal actions become more dist…

Taxing billionaires is great and all, but we could build systems where billionaires are impossible. Is hoarding wealth and using it to control people even something we should consider part of a functional and humane system? Any system where one group of people doesn't have rights means that anyone can be stripped of their rights, like has happened with all the US citizens who've been illegally detained and deported by ICE. Does the concept of "rights" that must be defended with violence, that can be stripped away by people who can exercise more violence, even make sense? Or should the bedrock of a functional system be the obligations that we have to each other and to society, that cannot be severed or taken from us, that tell us we *must* defend regardless of whether systemic oppression will impact us or not?

The US cannot be fixed. The economic system is a ponzi scheme that has been patched again and again, but has finally run out of options. Racism, sexism, and Christian nationalism are baked into the system at every level. Trump gutted the system of soft power that held the US economy together, now there is only a slow decline. Even after he's gone, the damage is done. Once we let go of how to fix something that cannot be fixed, we can start to imagine something that cannot be achieved within the current system.

We show that for every integer $k \geq \max(1, n-2)$, the $kd$th Veronese subring $R^{(kd)}$ is generated in degree 1, which implies that the line bundle $\mathcal{O}(kd)$ is very ample on the scheme $\operatorname{Proj}(R)$.

A novel random field model for the reconstruction of inhomogeneous turbulence from characteristic flow quantities has been recently introduced and analyzed by the authors. This article concerns the numerical approximation and implementation of the model and discusses its key features by means of numerical simulations. We present an effective discretization scheme based on a randomized quadrature method for stochastic integrals. The convergence of the scheme is verified analytically and its algo…

Euler-type approximation for the invariant measure: An abstract framework
We establish a general framework to study the rate of convergence of a Euler type approximation scheme with decreasing time steps to the invariant measure, for a general class of stochastic systems. The error is measured in general Wasserstein distances, which enables to encompass cases with non global contractivity conditions. Our main assumption is a coupling property which is expressed in terms of the one-step approximation. We show that the proposed set-up can be applied to a wide range of …

Tailoring interaction ranges in atom arrays
We introduce a method to synthetically engineer the range of dipolar interactions in tweezer atom arrays by effectively modifying the modes of the electromagnetic vacuum with far-detuned relay atoms. We derive equations of motion for the atoms of interest after adiabatic elimination of the relay atoms. We show the effectiveness of the scheme for realistic experimental parameter regimes with circular and low-angular-momentum Rydberg atom states.

An efficient spline-based scheme on Shishkin-type meshes for solving singularly perturbed coupled systems with Robin boundary conditions
In this paper, we investigate a weakly coupled system of singularly perturbed linear reaction-diffusion equations with Robin boundary conditions, where the leading terms are multiplied by small positive parameters that may differ in magnitude. The solution to this system exhibits overlapping and interacting boundary layers. To appropriately resolve these layers, we employ a standard Shishkin mesh and propose a novel modification of Bakhvalov-Shishkin mesh. A cubic spline approximation is applie…

Efficient and High-Accuracy Secure Two-Party Protocols for a Class of Functions with Real-number Inputs
In two-party secret sharing scheme, values are typically encoded as unsigned integers $\mathsf{uint}(x)$, whereas real-world applications often require computations on signed real numbers $\mathsf{Real}(x)$. To enable secure evaluation of practical functions, it is essential to computing $\mathsf{Real}(x)$ from shared inputs, as protocols take shares as input. At USENIX'25, Guo et al. proposed an efficient method for computing signed integer values $\mathsf{int}(x)$ from shares, which can be ex…

An important aspect of any grid-connected converter control strategy is the handling of grid-fault scenarios such as symmetrical and asymmetrical short-circuit faults. This pap…

In this paper, we present the first fault-tolerant blind verification scheme for universal quantum computations able to handle secret-depende…

Device-to-device (D2D) communication is one of the most promising techniques for future wireless cellular communication systems. This paper considers coded caching in a partially cooperative wireless D2D network, where only a subset of users transmit during delivery, while all users request files. The non-transmitting users are referred to as selfish users. All existing schemes that do not require knowledge of the identity of selfish users before content placement are limited to the high-memory…

Motivic homotopy theory for perfect schemes
We construct a perfect version of Morel--Voevodsky's motivic homotopy category over a perfect base scheme in positive characteristic. By checking the axioms of a coefficient system, we establish a six-functor formalism. We show that multiplication by $p$ is already invertible in the perfect motivic homotopy catgory. By work of Elmanto--Khan the functor sending an $\mathbb{F}_p$-scheme $S$ to the category $\mathrm{S}\mathcal{H}(S)[1/p]$ is invariant under universal homeomorphisms, hence under pe…

Resonant production of sterile neutrino dark matter with a refined numerical scheme
The existence of a large primordial neutrino asymmetry is an intriguing possibility, both observationally and theoretically. Such an asymmetry can lead to the resonant production of $\mathrm{keV}$-scale sterile neutrinos, which are a fascinating candidate for dark matter. In this paper, we comprehensively revisit the resonant production processes with a refined numerical analysis, adopting a dynamical discretization of momentum modes to take care of the sharpness of the resonance. We find param…

These quantities are obtained by solving elliptic and parabolic partial differential equations (PDEs), respectively. To support practical applications, we propose a numerical scheme implemente…

We then prove that the orders of matrices with the specified condition are limited to $2, 4$ or $8$. Using these matrices, we construct essentially two new proper Jordan schemes of orders $16$ and $32$. Finally, we analyze the structures of the real adjacency Jordan algebras of these Jordan schemes and prove that they are the …

A Gentle Introduction to Blind signatures: From RSA to Lattice-based Cryptography
Blind signatures were first introduced by David Chaum. They allow a user to have a message signed by a signer without revealing the message itself. This property is particularly useful in applications such as electronic voting and digital cash, where user anonymity is important. In a blind signature scheme, the user blinds their message before sending it to the signer, who signs the blinded message. The user then unblinds the signed message to obtain a valid signature that can be verified publi…

Second, $X$ is an étale $F$-bundle over some projective $Σ$-scheme, where $F$ is the flag variety of the adjoint Chevalley group over the integers defined by $C$. In particular, if the simple roots generate the Néron--Severi group of $X$ relative to $Σ$ and $X$ is cohomologically flat …

Higher thresholds offer more security, but also risk locking the user out of his own funds. The optimal threshold balances these twin effects. Interventi…

Assessing the dynamical assumptions in Tsirelson inequality tests of non-classicality in harmonic oscillators
"Macrorealism" posits that a system possesses definite properties at all times and that we can discover these properties, in principle, without disturbing the system's subsequent behaviour. The Leggett-Garg inequalities are derived under these assumptions and are readily violated by standard quantum mechanics, thereby providing a scheme to test whether demonstrably macroscopic systems can exhibit quantum coherence. Unfortunately, Leggett-Garg tests suffer from the ineludible clumsiness loophole…
