A PNT equivalence for Beurling numbers

Functiones et Approximatio Commentarii Mathematici, 2012
The objective of the paper is to investigate equivalences between the prime number theorem and the sharp Merten's formula for Beurling generalized numbers introduced in [\textit{A. Beurling}, Acta Math. 68, 255--291 (1937; Zbl 0017.29604)]. Beurling generalized numbers form a multiplicative semigroup \(\mathcal{N}\subset\mathbb{R}\) generated by ...

The slow emergence of the rational investor: Grain markets and grain storage of rural estates in western Germany, eighteenth and early nineteenth centuries

The Economic History Review, Volume 79, Issue 3, Page 1235-1264, August 2026.
Abstract We develop new datasets of monthly grain prices in 14 urban markets and of the storage and marketing of grain by 5 rural estates located in western Germany between the late seventeenth century and c. 1860. We explore whether observed patterns of monthly prices, sales, and storage of grain are consistent with the rational competitive storage ...

Molecular Glue cc‐885 Inhibits VHL‐Deficient Clear Cell Renal Cell Carcinoma via ETS1 Degradation

Advanced Science, Volume 13, Issue 42, 28 July 2026.
VHL‐deficient kidney cancer lacks effective treatments. This study reveals that the molecular glue degrader cc‐885 hijacks the cellular recycling system to selectively destroy the oncogenic protein ETS1, effectively killing VHL‐mutant tumors. Combining CC‐885 with the approved drug belzutifan achieves powerful synergy, offering a promising new ...

Novel fluorescent amphiphilic block copolymers: photophysics behavior and interactions with DNA

eXPRESS Polymer Letters, 2007
In this study, novel amphiphilic fluorescent copolymers poly(N-vinylpyrrolidone)-b-poly(N-methacryloyl-N'-(α-naphthyl)thiourea) (PVP-b-PNT) were synthesized via ATRP with poly(N-vinylpyrrolidone)-Cl as macroinitiator and N-methacryloyl-N'-α ...

How to Account for Past Selection When Maternal Effects Are Cascading

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Many forms of maternal effects are said to be ‘cascading’, in which an individual's phenotype is partially a function of its mother's phenotype and hence also partially a function of the phenotypes of its previous ancestors. We develop a quantitative genetics modelling framework that treats past maternal states as being under selection in the current ...

Best Integer Equivariant (BIE) Ambiguity Resolution Based on Tikhonov Regularization for Improving the Positioning Performance in Weak GNSS Models

Remote Sensing
In complicated scenarios, due to the low precision of float solutions and poor reliability of fixed solutions, it is challenging to achieve a balance between accuracy and reliability of the integer least squares (ILS) estimation. To address this dilemma,

Principles of Biocompatible Nanotube Design for High‐Performance Biomaterials

WIREs Nanomedicine and Nanobiotechnology, Volume 18, Issue 4, July/August 2026.
Schematic overview of nanotube‐based biomaterials for biomedical applications. ABSTRACT Nanotubes are one‐dimensional tubular structures characterized by nanoscale radial dimensions and micrometer‐scale axial lengths. Their hollow inner cavity confers a high specific surface area and distinctive physicochemical properties, enabling remarkable potential

Photoperiod‐Regulated Thermal Tolerance of the Non‐Diapausing Insect Ceratitis capitata (Diptera: Tephritidae)

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 725-735, July 2026.
Developmental photoperiodic exposure (photoacclimation) from egg to adult emergence alters thermal tolerance in Ceratitis capitata. Flies reared under contrasting photoperiods (0:24, 8:16, 14:10, and 24:0 L:D) showed significant shifts in both CTmin and CTmax, whereas adult‐only photoacclimation affected CTmax but not CTmin.
