A political perspective on the power of data reuse
Discussions of archaeological data reuse usually focus on technical and methodological questions: formats, metadata, ontologies and workflows. This contribution addresses a dimension that is rarely made explicit, namely the politics of decision-making that surrounds research data...

By mapping each of the 240 E8 root vectors onto residues modulo 240 and weighting them with the golden‑ratio phase factor φ^n, the resulting interference spectrum exhibits sharp peaks when the cumulative phase aligns with the 132 Hz base frequency multiplied by φ^k. These peaks c...

Abstract Offshore and marine structures increasingly utilise Functionally Graded Materials (FGMs) because of their superior stiffness and enhanced resistance to damage under combined vibration and cyclic loading induced by waves, wind and operational conditions. This study presen...

Causality: Effects-of-Causes, Causes-of-Effects, and Question-Design Fit
Causal claims sit at the center of many fields of inquiry, including tourism research, yet causal questions do not all ask the same thing. One class of questions asks what happens when a researcher, manager, or policymaker changes a condition ( effects-of-causes ). Another asks w...

Parkinson's disease is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons, leading to symptoms such as tremors and gastrointestinal dysfunction. Previous studies have shown reduced gut microbial diversity and imbalances in Parkinson’s disea...

Amyloid β peptides alter redox status and oxygen transport function of red blood cells
Abstract Patients with Alzheimer’s disease (AD) exhibit reduced cerebral venous oxygen saturation, that progresses with disease severity and correlates with cognitive decline. The underlying causes of this hypoxia, however, remain unclear. The accumulation of beta-amyloid (Aβ 42...

The number of odd spanning trees in almost multipartite graphs
This paper combines the Weighted Matrix-Tree Theorem with Boolean function analysis and the Schur complement decomposition method to study the enumeration of odd spanning trees, in which every vertex has odd degree, in almost multipartite graphs, and derives an explicit formula f...

The phrase “AI democratizes legal analysis” circulates unsorted. This work sorts the three layers wrapped inside it — access to documents, the capacity to produce a deep diagnosis, and the examinability of the work — and then holds one position: that democratization is arriving a...

Peptide receptor radionuclide therapy (PRRT) is an established treatment of advanced well-differentiated neuroendocrine tumors (NETs) expressing somatostatin receptors. Although generally well tolerated, PRRT may precipitate or exacerbate pre-existing hormonal syndromes in patien...

Previous studies have shown that E. coli B23 cells pretreated with a sub-inhibitory concentration of the aminoglycoside kanamycin develop short term (1.5 hour) resistance against lethal concentrations of tetracycline, ampicillin, streptomycin and kanamycin, as well as long term (...

Gi Signaling Does Not Differentiate Hallucinogenic from Nonhallucinogenic 5-HT2A Receptor Agonists
Abstract A recent publication by Xu et al. suggests that Gi activation following 5-HT2AR stimulation differentiates hallucinogenic from nonhallucinogenic agonists. Here, we reanalyze the author’s source data to demonstrate that Gi activation is less predictive of hallucinogenic p...

A CRC–MYB chromatin loop controls auxin-mediated nectary growth in Arabidopsis
Abstract Floral nectaries, typically located at stamen bases, secrete sugar-rich nectar containing diverse secondary metabolites. Despite their defined position and specialized function, the mechanisms governing nectary formation remain unclear. Using publicly available single-nu...

Recovering the level of distribution x^{1/2} for the orders of y^2 = x^3 - x modulo p
Iwaniec and Jimenez Urroz (Ann. Sc. Norm. Super. Pisa 9 (2010), 815-832) proved that for >> x/(log x)^2 primes p <= x, p = 1 (mod 4), the order of the reduction modulo p of the elliptic curve y^2 = x^3 - x is eight times an integer with at most two prime factors. Xie (arXiv:2504....
