High-resolution sound source localization via non-synchronous measurements based on symmetric sparse planar array in the differential domain.

open access: yesISA transactions
To overcome the resolution limitations of conventional array topologies and non-synchronous measurement (NSM), the extended symmetric coprime and symmetric nested planar arrays with high-performance difference co-array are designed. A localization method

The dimension of well approximable numbers

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract In this survey article, we explore a central theme in Diophantine approximation inspired by a celebrated result of Besicovitch on the Hausdorff dimension of well approximable real numbers. We outline some of the key developments stemming from Besicovitch's result, with a focus on the mass transference principle, ubiquity and Diophantine ...

Siegel–Veech constants for cyclic covers of generic translation surfaces

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We compute the asymptotic number of cylinders, weighted by their area to any nonnegative power, on any cyclic branched cover of any generic translation surface in any stratum. Our formulae depend only on topological invariants of the cover and number‐theoretic properties of the degree: in particular, the ratio of the related Siegel–Veech ...

One‐level densities in families of Grössencharakters associated to CM elliptic curves

open access: yesMathematika, Volume 72, Issue 1, January 2026.
Abstract We study the low‐lying zeros of a family of L$L$‐functions attached to the complex multiplication elliptic curve Ed:y2=x3−dx$E_d \;:\; y^2 = x^3 - dx$, for each odd and square‐free integer d$d$. Specifically, upon writing the L$L$‐function of Ed$E_d$ as L(s−12,ξd)$L(s-\frac{1}{2}, \xi _d)$ for the appropriate Grössencharakter ξd$\xi _d$ of ...

Iitaka fibrations and integral points: A family of arbitrarily polarized spherical threefolds

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 6, December 2025.
Abstract Studying Manin's program for a family of spherical log Fano threefolds, we determine the asymptotic number of integral points whose height associated with an arbitrary ample line bundle is bounded. This confirms a recent conjecture by Santens and sheds new light on the logarithmic analog of Iitaka fibrations, which have not yet been adequately

Het volgen van meerdere objecten met behulp van een digitale bundelvormingsantenne ,, ,,

open access: yes, 2016
The technique of using multiple antennas or an antenna array, is well-known to provide spatial diversity in a wireless communication system. Exploiting the phase information of the received signals from all elements of the antenna array enables the ...
