On the Approximation of the Hardy Z-Function via High-Order Sections

open access: yesAxioms
The Z-function is the real function given by Z(t)=eiθ(t)ζ12+it, where ζ(s) is the Riemann zeta function, and θ(t) is the Riemann–Siegel theta function. The function, central to the study of the Riemann hypothesis (RH), has traditionally posed significant

Spatio‐Temporal Resolution of Microbial Functions and Taxa Associated With Cyanobacterial Harmful Algae Blooms Along a 500‐Km Aquatic Continuum in the Lake Erie Watershed

open access: yesEnvironmental Microbiology, Volume 27, Issue 10, October 2025.
The aquatic microbiome can influence cyanobacterial harmful algal blooms. Abundances of genes and transcripts for phosphorus acquisition, denitrification and nitrogen fixation were higher upstream, whereas in Lake Erie genes and transcripts for microcystin production were higher.

The Effect of the Density of Square-Free ωp-numbers on the Bounds of Beurling Counting Function

open access: yesZanco Journal of Pure and Applied Sciences
Primitive weird numbers are weird numbers which are not a multiple of any smaller weird numbers. The goal of this work is to use a square-free primitive weird number x=ab where  b be an increasing sequence of prime numbers such that q1  is greater than ∏

Stimulating the Stimulated Cortex—Frontocortical Anodal Electric Stimulation Combined With Closed‐Loop Acoustic Stimulation During Sleep Impairs Memory in Subjects With High Cognitive Ability

open access: yesEuropean Journal of Neuroscience, Volume 62, Issue 7, October 2025.
Can responsiveness to closed‐loop acoustic stimulation (CLAS) be modulated by anodal transcranial direct current stimulation (AmodCLAS) during sleep? Such induced differences in excitability may partially explain variability in CLAS efficacy. AmodCLAS affected offline detected slow oscillations, reduced sleep efficiency, and REM sleep.

An Equivalent to the Riemann Hypothesis

open access: yes, 2023
The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part $\frac{1}{2}$. It is considered by many to be the most important unsolved problem in pure mathematics. There are several statements equivalent to the famous Riemann hypothesis.

Proof of the Riemann Hypothesis

open access: yes
Background: The non-trivial zeros of the Riemann zeta function govern prime distributions, and the Riemann Hypothesis states that they all lie on the critical line $\operatorname{Re}s=\tfrac12$. Methods: We place a self-adjoint restriction $R_{\mathrm{PW}}$ of the first-order differentiation operator on a weighted Hilbert space $H_\alpha$ and, under ...

Coping With Political‐Ideological Pressure: How Street‐Level Bureaucrats Shield Policy Implementation From Politicization

open access: yesGovernance, Volume 38, Issue 4, October 2025.
ABSTRACT While pursuing a professional delivery of public services, street‐level bureaucrats increasingly face intense political‐ideological pressure. Yet, preceding scholars have barely explored how they manage to resist it. Addressing this gap, the paper presents a concept of the coping mechanisms street‐level bureaucrats employ to shield their ...

Vanishing of Schubert coefficients via the effective Hilbert nullstellensatz

open access: yesForum of Mathematics, Sigma
Schubert Vanishing is a problem of deciding whether Schubert coefficients are zero. Until this work it was open whether this problem is in the polynomial hierarchy ${{\mathsf {PH}}}$ .

The art of sleep: examining sleep strategies in the general population with a focus on the use of music for sleep

open access: yesJournal of Sleep Research, Volume 34, Issue 5, October 2025.
Summary Insomnia is highly prevalent and associated with serious health issues. Despite the negative impact of poor sleep on mind and body, most people do not seek treatment. This study aimed to examine the strategies used to improve sleep in the general population with a particular focus on music.
