Complementary legs and symplectic rational balls

Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.
Abstract We show that a small Seifert fibered space with complementary legs does not symplectically bound a rational homology ball for at least one choice of orientation. In the case e0⩽−1$e_0\leqslant -1$, we characterize when a small Seifert fibered space with uniquely complementary legs symplectically bounds a rational homology ball.

Near-Field Localization With Coprime Array

Proceedings of the 30th Annual International Conference on Mobile Computing and Networking
Large-aperture coprime arrays (CAs) are expected to achieve higher sensing resolution than conventional dense arrays (DAs), yet with lower hardware and energy cost. However, existing CA far-field localization methods cannot be directly applied to near-field scenarios due to channel model mismatch.

On the detection of knots by their traces in high dimensions

Proceedings of the London Mathematical Society, Volume 133, Issue 4, October 2026.
Abstract For every n⩾4$n\geqslant 4$, we demonstrate the existence of non‐isotopic, smooth (n−2)$(n-2)$‐knots in Sn$S^n$ with diffeomorphic traces. We give two proofs: the first by generalising the RBG link construction to all dimensions, and the second as an application of work of Plotnick.

Advances in Cold‐Plasma Technology for Legume Seeds: Mechanisms, Nutritional Quality Improvement, Food Safety and Sustainable Agriculture

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Cold plasma (CP), a nonthermal ionised gas rich in reactive oxygen and nitrogen species (RONS), has emerged as a sustainable technology for enhancing legume production and quality. This review summarises current advances in CP applications in legumes, focusing on seed germination, seedling vigour, nutrient enhancement, antinutrient reduction ...

Direct Position Determination of Multiple Non-Circular Sources with a Moving Coprime Array

Sensors, 2018
Direct position determination (DPD) is currently a hot topic in wireless localization research as it is more accurate than traditional two-step positioning.

A higher rank shifted convolution problem with applications to L$L$‐functions

Proceedings of the London Mathematical Society, Volume 133, Issue 3, September 2026.
Abstract While several instances of shifted convolution problems for GL(3)×GL(2)${\rm GL}(3) \times {\rm GL}(2)$ have been solved, the case where one factor is the classical divisor function and one factor is a GL(3)${\rm GL}(3)$ Fourier coefficient has remained open. We solve this case in the present paper.

Pinwheels in symplectic rational and ruled surfaces and non‐squeezing of rational homology balls

Journal of Topology, Volume 19, Issue 3, September 2026.
Abstract We use almost toric fibrations and the symplectic rational blow‐up to determine when certain Lagrangian pinwheels, which we call liminal, embed in symplectic rational and ruled surfaces. The case of L2,1$L_{2,1}$‐pinwheels, namely Lagrangian RP2s$\mathbb {R}P^2{\rm s}$, answers a question of Kronheimer in the negative, exhibiting a symplectic ...

Two-Dimensional Direction of Arrival Estimation for Coprime Planar Arrays via Polynomial Root Finding Technique

IEEE Access, 2018
In this paper, the problem of 2-D direction-of-arrival (2-D-DOA) estimation for coprime planar arrays is investigated, and a method based on the polynomial root finding technique with high accuracy and computational efficiency is proposed.

Optical Phased Arrays on Photonic Integrated Circuit Platforms: Challenges, Opportunities, and Future Applications [PDF]

Nanophotonics
Integrated optical phased arrays are emerging as scalable engines for solid‐state beam steering and programmable wavefront control. This Review maps the field from beam‐steering principles and core building blocks to material platforms, system‐level bottlenecks, and application frontiers, highlighting how heterogeneous integration, aperiodic ...

Cluster scattering diagrams via quiver moduli and tight gradings

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract We study rank‐2 cluster scattering diagrams through moduli spaces of quiver representations and a recently developed combinatorial framework of tight gradings. Combining quiver‐theoretic and combinatorial methods, we prove and extend a collection of conjectures posed by Elgin–Reading–Stella concerning the structural and enumerative properties ...
