On the study of general multifractal analysis of sets using vector-valued functions

open access: yesAIMS Mathematics
In this work, we present a general approach to computing the Hewitt-Stromberg dimensions of a set $ A $ in a metric space. This technique, originally introduced by Cutler and Tricot and later expanded by Ben Nasr et al., offers a generalization of ...

What Voting Power Cannot Be

open access: yesNoûs, EarlyView.
ABSTRACT “Almost everyone,” Ronald Dworkin wrote in Sovereign Virtue, “assumes that democracy means equal voting power.” What, then, is voting power? The standard view defines it as the probability that a vote changes the outcome assuming that each possible combination of votes is equiprobable.

Weak convergence to the t-distribution [PDF]

open access: yes
We present a new limit theorem for random means: if the sample size is not deterministic but has a negative binomial or geometric distribution, the limit distribution of the normalised random mean is a t-distribution with degrees of freedom depending on ...

Spatio‐Temporal Diversity of Calcium Activity in Microglia

open access: yesGlia, Volume 74, Issue 3, March 2026.
Ca2+ activity mostly occurs in microglial processes and stays localized. When it spreads, it often shows a directional bias and is constrained by branch points. Activity strongly relies on P2Y12 receptors and is shaped by neuronal activity. ABSTRACT Microglia, the brain's innate immune cells, possess complex, highly motile branched processes. These act

Simple 3‐Designs of PSL ( 2 , 2 n ) With Block Size 13

open access: yesJournal of Combinatorial Designs, Volume 34, Issue 3, Page 119-138, March 2026.
ABSTRACT This paper focuses on the investigation of simple 3‐( 2 n + 1 , 13 , λ ) designs admitting PSL ( 2 , 2 n ) as an automorphism group. Such designs arise from the orbits of 13‐element subsets under the action of PSL ( 2 , 2 n ) on the projective line X = GF ( 2 n ) ∪ { ∞ }, and any union of these orbits also forms a 3‐design.

Continuous Stieltjes-Wigert Limiting Behaviour of a Family of Confluent q-Chu-Vandermonde Distributions

open access: yesAxioms, 2014
From Kemp [1], we have a family of confluent q-Chu- Vandermonde distributions, consisted by three members I, II and III, interpreted as a family of q-steady-state distributions from Markov chains.

A simple test for the violation of the non-satiation axiom under uncertainty: The theory [PDF]

open access: yes
The validity of most axioms which underlie the expected utility model has been the object of intense empirical testing. These include the independence, betweenness, transitivity, monotonicity, reduction, and non-satiation axioms.

Stagewise Boosting Distributional Regression

open access: yesStat, Volume 15, Issue 1, March 2026.
ABSTRACT Distributional regression extends generalized additive models by linking all distributional parameters to covariates. Gradient boosting is among the most effective estimation techniques for such models, yet it can suffer from vanishing gradients, resulting in unstable updates and weak variable selection.
