Statistical Efficiency of Distributional Temporal Difference
Distributional reinforcement learning (DRL), which cares about the full distribution of returns instead of just the mean, has achieved empirical success in various domains. One of the core tasks in the field of DRL is distributional policy evaluation, which involves estimating the return distribution $η^π$ for a given policy $π$. A distributional temporal difference (TD) algorithm has been accordingly proposed, which is an extension of the temporal difference algorithm in the classic RL lite…

Difference of solutions for the inversion problem of ultra-elliptic integrals
Let $V$ be a hyperelliptic curve of genus 2 defined by $Y^2=f(X)$, where $f(X)$ is a polynomial of degree 5. The sigma function associated with $V$ is a holomorphic function on $\mathbb{C}^2$. For a point $P$ on $V$, we consider the problem to express the $X$-coordinate of $P$ in terms of the image of $P$ under the Abel-Jacobi map. Two meromorphic functions $f_2$ and $g_2$ on $\mathbb{C}^2$ which give solutions of this problem are known. Since $f_2$ and $g_2$ coincide on the zero set of the sig…

The Role of Carbon Pricing in Food Inflation: Evidence from Canadian Provinces
Carbon pricing, including carbon tax and cap-and-trade, is usually seen as an effective policy tool for mitigating emissions. Although such policies are often perceived as worsening affordability issues, earlier studies find insignificant or deflationary effects of carbon pricing. We verify this result for the food sector by using provincial-level data on food CPI from Canada. By using a staggered difference-in-difference (DiD) approach, we show that the deflationary effects of carbon pricing o…

Energy resolution is a measure of the smallest possible difference in energy of the impinging photons, Delta E, that the detector can identify and is of critical importance for many applications. Limits to the energy resolution cause by the Fano effect, amplifier noise, current inhomogeneities, and readout sampling frequency are taken into consideration for this …

The alternative is to compare the mean squared z-scores or scaled errors (ZMS) to 1. Both approaches might lead to different conclusion, as illustrated on an ensemble of datasets from the recent machine learning uncertainty quantifi…

We classify order $3$ linear difference operators over $\mathbb{C}(x)$ that are solvable in terms of lower order difference operators. To prove this result, we introduce the notion of absolute irreducibility for difference modules, and classify modules that are irreducible but not absolutely irreducible by using restricted and induced modules. We also show how restriction and induction give coordinate-free formulations of sectioning and interlacing of sequences.

Many interesting families of polynomials are indexed by permutations or related objects, and are defined by applying divided difference operators, modified by polynomials, on some initial base case. The fact that these constructions produce well-defined polynomials is based on the applied modified divided difference operators satisfying the braid relations. We thus determine all the families of polynomial divided difference operators that satisfy the braid relations.

LimberJack.jl: auto-differentiable methods for angular power spectra analyses
We present LimberJack.jl, a fully auto-differentiable code for cosmological analyses of 2 point auto- and cross-correlation measurements from galaxy clustering, CMB lensing and weak lensing data written in Julia. Using Julia's auto-differentiation ecosystem, LimberJack.jl can obtain gradients for its outputs up to an order of magnitude faster than traditional finite difference methods. This makes LimberJack.jl greatly synergistic with gradient-based sampling methods, such as Hamiltonian Monte C…

A biological circuit to anticipate trend
Organisms gain by anticipating future changes in the environment. Those environmental changes often follow stochastic trends. The greater the slope of the trend, the more likely the trend's momentum carries the future trend in the same direction. This article presents a simple biological circuit that measures the momentum, providing a prediction about future trend. The circuit calculates the momentum by the difference between a short-term and a long-term exponential moving average. The time len…

Birds of a Feather: Resolving Stellar Mass Assembly With JWST/NIRCam in a Pair of Kindred $z \sim 2$ Dusty Star-forming Galaxies Lensed by the PLCK G165.7+67.0 Cluster
We present a new parametric lens model for the G165.7+67.0 galaxy cluster, which was discovered with $Planck$ through its bright submillimeter flux, originating from a pair of extraordinary dusty star-forming galaxies (DSFGs) at $z\approx 2.2$. Using JWST and interferometric mm/radio observations, we characterize the intrinsic physical properties of the DSFGs, which are separated by only $\sim 1^{\prime\prime}$ (8 kpc) and a velocity difference $ΔV \lesssim 600~{\rm km}~{\rm s}^{-1}$ in the so…

Solving Partial Differential Equations Using Artificial Neural Networks
Partial differential equations have a wide range of applications in modeling multiple physical, biological, or social phenomena. Therefore, we need to approximate the solutions of these equations in computationally feasible terms. Nowadays, among the most popular numerical methods for solving partial differential equations in engineering, we encounter the finite difference and finite element methods. An alternative numerical method that has recently gained popularity for numerically solving par…

Hubble tension may indicate time-dependent dark matter energy density
The values of Hubble constant H0 by direct measurements with standard distance ladder are typically larger than those obtained from the observation of cosmic microwave background and the galaxy survey with inverse distance ladder. On the other hand, although the errors are still large, various determinations of the value of matter density parameter Omega_m are consistent with each other. Therefore, it is possible that the difference in Hubble constant is translated to the difference of physical…

Valuation of Power Purchase Agreements for Corporate Renewable Energy Procurement
Corporate renewable power purchase agreements (PPAs) are long-term contracts that enable companies to source renewable energy without having to develop and operate their own capacities. Typically, producers and consumers agree on a fixed per-unit price at which power is purchased. The value of the PPA to the buyer depends on the so called capture price defined as the difference between this fixed price and the market value of the produced volume during the duration of the contract. To model the…

It is a little amazing to me to see people who have been rendered incapable of seeing any difference between Biden and Trump because Biden has taken the slow-centrist-Democrat approach to Netanyahu's destruction of the Gaza strip. There's a lot going on there, Netanyahu is barely in power, the best goal is "how quickly can the atrocity stop?" not "how quickly can we claim we're no longer involved in the atrocity that has not stopped?"

Dual-comb mode-locked Yb:CALGO laser based on cavity-shared configuration with separated end mirrors
Dual-comb spectroscopy typically requires the utilization of two independent and phase-locked femtosecond lasers, resulting in a complex and expensive system that hinders its industrial applications. Single-cavity dual-comb lasers are considered as one of the primary solution to simplify the system. However, controlling the crucial parameter of difference in repetition rates remains challenging. In this study, we present a dual-comb mode-locked Yb:CALGO laser based on a cavity-shared configurat…

Pseudo P-values for Assessing Covariate Balance in a Finite Study Population with Application to the California Sugar Sweetened Beverage Tax Study
Assessing covariate balance (CB) is a common practice in various types of evaluation studies. Two-sample descriptive statistics, such as the standardized mean difference, have been widely applied in the scientific literature to assess the goodness of CB. Studies in health policy, health services research, built and social environment research, and many other fields often involve a finite number of units that may be subject to different treatment levels.

Zero order meromorphic solutions of $q$-difference equations of Malmquist type
We consider the first order $q$-difference equation \begin{equation}\tag† f(qz)^n=R(z,f), \end{equation} where $q\not=0,1$ is a constant and $R(z,f)$ is rational in both arguments. When $|q|\not=1$, we show that, if $(†)$ has a zero order transcendental meromorphic solution, then $(†)$ reduces to a $q$-difference linear or Riccati equation, or to an equation that can be transformed to a $q$-difference Riccati equation. In the autonomous case, explicit meromorphic solutions of $(…

Happy Appomattox Day! Frederick Douglass has some strong words for remembering what the victory over the Confederacy meant.
We are sometimes asked, in the name of patriotism, to forget the merits of this fearful struggle, and to remember with equal admiration those who struck at the nation's life and those who struck to save it, those who fought for slavery and those who fought for liberty and justice.
I am no minister of malice. I would not strike the fallen. I would not repel the repentant; but may my right hand forget her cunning and my tongue cleave to the roof of my mouth, if I forget the difference between the parties to that terrible, protracted, and bloody conflict.
...But we are not here to applaud manly courage, save as it has been displayed in a noble cause. We must never forget that victory to the rebellion meant death to the Republic."

An Optimal Transport Approach to Estimating Causal Effects via Nonlinear Difference-in-Differences
We propose a nonlinear difference-in-differences method to estimate multivariate counterfactual distributions in classical treatment and control study designs with observational data. Our approach sheds a new light on existing approaches like the changes-in-changes and the classical semiparametric difference-in-differences estimator and generalizes them to settings with multivariate heterogeneity in the outcomes. The main benefit of this extension is that it allows for arbitrary dependence and …

An Efficient Finite Difference Approximation via a Double Sample-Recycling Approach
Estimating stochastic gradients is pivotal in fields like service systems within operations research. The classical method for this estimation is the finite difference approximation, which entails generating samples at perturbed inputs. Nonetheless, practical challenges persist in determining the perturbation and obtaining an optimal finite difference estimator in the sense of possessing the smallest mean squared error (MSE). To tackle this problem, we propose a double sample-recycling approach…

A grid-overlay finite difference method for the fractional Laplacian on arbitrary bounded domains
A grid-overlay finite difference method is proposed for the numerical approximation of the fractional Laplacian on arbitrary bounded domains. The method uses an unstructured simplicial mesh and an overlay uniform grid for the underlying domain and constructs the approximation based on a uniform-grid finite difference approximation and a data transfer from the unstructured mesh to the uniform grid. The method takes full advantages of both uniform-grid finite difference approximation in efficient…
