Quantum algorithms for hidden nonlinear structures

open access: yes, 2007
Attempts to find new quantum algorithms that outperform classical computation have focused primarily on the nonabelian hidden subgroup problem, which generalizes the central problem solved by Shor's factoring algorithm.

Testing the underdog entrepreneurship theory with specialised Australian immigrant data

open access: yesGeographical Research, Volume 63, Issue 4, Page 533-552, November 2025.
Using the 2021 Australian Census and Migrants Integrated Dataset (ACMID), we explore the explanatory value of Miller and Le Breton‐Miller’s underdog entrepreneurship theory (2017): examining its implications in the Australian context, finding some good support for it, and proposing some extensions. Abstract Migrants account for a significant proportion

Airy Sums, Kloosterman Sums, and Salié Sums

open access: yesJournal of Number Theory, 1997
In 1993 \textit{W. Duke} and \textit{H. Iwaniec} proved that a certain class of cubic exponential sums can be expressed through Kloosterman sums twisted by a cubic character [Contemp. Math. 143, 255-258 (1993; Zbl 0792.11029)]. Their proof made use of one of the Davenport-Hasse theorems.

Rethinking Support Policies: The Role of Belonging in Entrepreneurial Ecosystems

open access: yesInternational Migration, Volume 63, Issue 6, November 2025.
ABSTRACT This article explores the importance of belongingness in migrant entrepreneurs' (MEs) engagement within entrepreneurial ecosystems (EEs), focusing on emotional and social dimensions often overlooked in favour of structural factors. Through two case studies in Germany's Ruhr area, the article demonstrates how a strong sense of belonging ...

Breeding for delayed bolting decelerated the circadian clock in cultivated lettuce

open access: yesNew Phytologist, Volume 248, Issue 4, Page 1892-1902, November 2025.
Summary Circadian clocks pace biological events and influence developmental traits, but their role in leafy crop domestication has remained unexplored. We investigated whether selection for delayed bolting during lettuce domestication targeted clock components.

Overexpression of StHsfA2 Enhances Thermotolerance and Promotes Tuberisation in Potato Under High Temperature Through StSP6A

open access: yesPlant Biotechnology Journal, Volume 23, Issue 11, Page 5045-5062, November 2025.
ABSTRACT High temperature (HT) is a major environmental stress that severely inhibits potato (Solanum tuberosum L.) tuberisation and yield. Heat shock transcription factors (Hsfs) are pivotal in plant thermotolerance, yet their roles in potato remain unclear. Here, we demonstrate that overexpression of StHsfA2, a rapidly HT–responsive HSF family member,

Weakly special threefolds and nondensity of rational points

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 5, November 2025.
Abstract We verify part of a conjecture of Campana predicting that rational points on the weakly special nonspecial simply connected smooth projective threefolds constructed by Bogomolov–Tschinkel are not dense. To prove our result, we establish fundamental properties of moduli spaces of orbifold maps, and prove a dimension bound for such moduli spaces

OPPOSITE‐SIGN KLOOSTERMAN SUM ZETA FUNCTION [PDF]

open access: yesMathematika, 2016
We study the meromorphic continuation and the spectral expansion of the oppposite sign Kloosterman sum zeta function, $$(2 \sqrt{mn})^{2s-1}\sum_{\ell=1}^\infty \frac{S(m,-n,\ell)}{\ell^{2s}}$$ for $m,n$ positive integers, to all $s \in \mathbb{C}$. There are poles of the function corresponding to zeros of the Riemann zeta function and the spectral ...

Prevalence and Risk of Violence Among People With Disabilities in China: A Meta‐Analysis of Observational Studies

open access: yesBrain and Behavior, Volume 15, Issue 9, September 2025.
Prevalence and risk of violence among people with disabilities in China is higher than global estimates. Significant moderators: age (preschool highest), perpetrator (caregivers > peers), violence type (emotional > physical), and educational setting (mainstream school > special school).
