Die Verwaltung entdeckt Matrix – nicht den Film, das Prototkoll. Esther Menhard berichtet: Statt weiter im OSCI-Altbau zu wohnen, zieht man ins offene Loft. Zwischen 900 Anforderungen und föderalem Klein-Klein droht auch dieser Digitalisierungsversuch im deutschen Verwaltungslabyrinth zu versanden. Digitalisierung, Reloaded!

Verwaltungsdigitalisierung: Arbeitsgruppe empfiehlt Matrix-Protokoll für Behördenkommunikation
Online-Kommunikation mit Behörden ist für Bürger*innen und Unternehmen kompliziert, für Verwaltungen oft teuer und aufwendig. Das soll sich ändern: Eine Arbeitsgruppe von IT-Architekten aus Bund und Ländern schlägt vor, wie alle von einer gemeinsamen Infrastruktur profitieren, und empfehlen das offene Kommunikationsprotokoll Matrix.

Effect of Insecurity on Agricultural Output in Benue State, Nigeria
This study examined the effect of insecurity on agricultural output in Benue state. A descriptive survey design was employed, and 400 respondents were purposively selected from insecurity-prone local government areas, namely, Guma LGA, Agatu LGA, Gwer LGA, Gwer-West LGA, Katsina-Ala LGA, Logo LGA, Ukum LGA and Kwande LGA. The data were collected through the administration of a questionnaire and were analysed using t tests and structural equation modelling (SEM). The t-test was used to compare f…

A Compartmental Model for Epidemiology with Human Behavior and Stochastic Effects
We propose a compartmental model for epidemiology wherein the population is split into groups with either comply or refuse to comply with protocols designed to slow the spread of a disease. Parallel to the disease spread, we assume that noncompliance with protocols spreads as a social contagion. We begin by deriving the reproductive ratio for a deterministic version of the model, and use this to fully characterize the local stability of disease free equilibrium points. We then append the determ…

Auto-Doubly Robust Estimation of Causal Effects on a Network
This paper develops new methods for causal inference in observational studies on a single large network of interconnected units, addressing two key challenges: long-range dependence among units and the presence of general interference. We introduce a novel network version of Augmented Inverse Propensity Weighted, which combines propensity score and outcome models defined on the network to achieve doubly robust identification and estimation of both direct and spillover causal effects. Under a ne…

Campana's orbifold conjecture for numerically equivalent divisors
We prove the following version of the Campana's orbifold conjecture: Let $X$ be a complex non-singular projective variety of dimension $n$. Let $D_1,\ldots,D_{n+1}$ be $\mathbb Z$-linearly independent effective divisors in ${\rm Div}(X)$ and $D:=D_1+\cdots+D_{n+1}$ be a normal crossing divisor of $X$. Assume furthermore that they are numerically parallel. Let $Δ=\sum_{i=1}^{n+1} (1-m_i^{-1}) D_i$ and let $f:\mathbb C\to (X,Δ) $ be an orbifold entire curve. Then, there exists a positive intege…

Cost Effective Designs For Next-Generation Radio Telescopes
Radio astronomy has entered its golden era, with many revolutionary facilities such as SKA, ngVLA, and LOFAR2.0 coming online in the next decade. These facilities are certain to redefine radio astronomy. However, on smaller scales-such as at institutional or amateur levels-radio astronomy is still mostly practiced for educational or personal interest. The primary reason small-scale radio astronomical experiments rarely produce cutting-edge scientific results is the limitation of funding availab…

A Refined Analysis of UCBVI
In this work, we provide a refined analysis of the UCBVI algorithm (Azar et al., 2017), improving both the bonus terms and the regret analysis. Additionally, we compare our version of UCBVI with both its original version and the state-of-the-art MVP algorithm. Our empirical validation demonstrates that improving the multiplicative constants in the bounds has significant positive effects on the empirical performance of the algorithms.

Mind the Gap: A Formal Investigation of the Relationship Between Log and Model Complexity -- Extended Version
Simple process models are key for effectively communicating the outcomes of process mining. An important question in this context is whether the complexity of event logs used as inputs to process discovery algorithms can serve as a reliable indicator of the complexity of the resulting process models. Although various complexity measures for both event logs and process models have been proposed in the literature, the relationship between input and output complexity remains largely unexplored. In…
