Generalization Bound for a General Class of Neural Ordinary Differential Equations
Neural ordinary differential equations (neural ODEs) are a popular type of deep learning model that operate with continuous-depth architectures. To assess how well such models perform on unseen data, it is crucial to understand their generalization error bounds. Previous research primarily focused on the linear case for the dynamics function in neural ODEs - Marion, P. (2023), or provided bounds for Neural Controlled ODEs that depend on the sampling interval Bleistein et al. (2023). In this wor…

Going Beyond Twin-width? CSPs with Unbounded Domain and Few Variables
We study a model of constraint satisfaction problems geared towards instances with few variables but with domain of unbounded size (udCSP). Our model is inspired by recent work on FPT algorithms for MinCSP where frequently both upper and lower bounds on the parameterized complexity of a problem correspond to $k$-variable udCSPs; e.g., the FPT algorithms for Boolean MinCSP (Kim et al., SODA 2023) and Directed Multicut with three cut requests (Hatzel et al., SODA 2023) both reduce to k-variable u…

Two classes of NMDS codes from Roth-Lempel codes
Since near maximum distance separable (NMDS) codes have good algebraic properties and excellent error-correcting capabilities, they have been widely used in various fields such as communication systems, data storage, quantum codes, and so on. In this paper, basing on the generator matrix of Roth-Lempel codes, we present two classes of NMDS codes which generalize Han's and Zheng's constructions in 2023 and 2025, respectively. And we also completely determine their weight distributions.

Ammonia in the hot core W51-IRS2: Maser line profiles, variability, and saturation
W51-IRS2 is known to be one of the most prolific sources of interstellar ammonia (NH$_3$) maser lines. So far, however, many of these inversion lines have rarely been studied. Here we report spectrally resolved line profiles for the majority of detected features and provide information on the variability of these maser components between 2012 and 2023. This includes the first tentative detection of a ($J$,$K$) = (5,2) maser in the interstellar medium and the first tentative detection of a (6,4)…

Temperature Sensitivity of Residential Energy Demand on the Global Scale: A Bayesian Partial Pooling Model
This paper contributes to the limited literature on the temperature sensitivity of residential energy demand on a global scale. Using a Bayesian Partial Pooling model, we estimate country-specific intercepts and slopes, focusing on non-linear temperature response functions. The results, based on data for up to 126 countries spanning from 1978 to 2023, indicate a higher demand for residential electricity and natural gas at temperatures below -5 degrees Celsius and a higher demand for electricity…

Der starke #Solarboom drückt die #Strompreise in Deutschland und macht neue #Offshore-#Windprojekte

Solarboom würgt Windkraft ab: "Niedrige Strompreise setzen dem Offshore-Zubau ein Ende"
2023 reißen sich die Bieter um deutsche Offshore-Flächen. Zwei Jahre später ist die Windkraft-Euphorie verpufft. Einer Expertin zufolge belasten steigende Stahlpreise und das China-Risiko die Branche. Und der Solarboom: "Wenn die Strompreise sinken, rechnet sich der Bau nicht mehr", sagt sie im Interview.
