Free energy expansions of a conditional GinUE and large deviations of the smallest eigenvalue of the LUE

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 12, Page 2247-2304, December 2025.
Abstract We consider a planar Coulomb gas ensemble of size N$N$ with the inverse temperature β=2$\beta =2$ and external potential Q(z)=|z|2−2clog|z−a|$Q(z)=|z|^2-2c \log |z-a|$, where c>0$c>0$ and a∈C$a \in \mathbb {C}$. Equivalently, this model can be realised as N$N$ eigenvalues of the complex Ginibre matrix of size (c+1)N×(c+1)N$(c+1) N \times (c+1)

Enhancing computation speed and accuracy in deep image prior‐based parameter mapping

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 6, Page 2654-2667, December 2025.
Abstract Purpose To make Deep Image Prior (DIP)‐based parameter mapping faster, more accurate, and suitable for clinical applications, with added support for multislice and 3D datasets. Methods DIP leverages the inherent structure of an untrained image generator to address various inverse imaging tasks, including denoising.

Target Return Strategy

open access: yesFinancial Review, Volume 60, Issue 4, Page 1483-1503, November 2025.
ABSTRACT We study the target return strategy (TRS), which exits the market once the return reaches a preset target. We show that the holding‐period return (HPR) cannot mean‐variance dominate TRS, but TRS can mean‐variance dominate HPR. We theoretically analyze TRS and quantitatively illustrate that training targets by a mean‐variance utility ...

Inviscid analysis of jet injection between two moving streams [PDF]

open access: yes
An analytical method is developed for determining the flow interaction when a two-dimensional jet is injected between two moving streams. The jet is flowing out of channel and is turned as it enters between the external streams.

Design and evaluation of a 3 million DN series-hybrid thrust bearing [PDF]

open access: yes
The bearing, consisting of a 150-mm ball bearing and a centrifugally actuated, conical, fluid-film bearing, was fatigue tested. Test conditions were representative of a mainshaft ball bearing in a gas turbine engine operating at maximum thrust load to ...

Describing a programme of implementation‐effectiveness research on the organization and implementation of frontline nursing care delivery into diverse health systems

open access: yesJournal of Advanced Nursing, Volume 81, Issue 11, Page 8036-8049, November 2025.
Abstract Aims The longitudinal programme of research described in this paper seeks to generate knowledge about factors influencing the implementation of a system‐level intervention, the clinical nurse leader care model, involving nurses as leaders at the frontlines of care and the outcomes achievable with successful implementation.

Using artificial intelligence to control fluid flow computations [PDF]

open access: yes
Computational simulation is an essential tool for the prediction of fluid flow. Many powerful simulation programs exist today. However, using these programs to reliably analyze fluid flow and other physical situations requires considerable human effort ...

Direct Kelvin‐Helmholtz Instability Detection at the Ionospheric E Region Electron Density

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract New high‐resolution measurements by Sanya incoherent scatter radar (ISR) employing a wide‐bandwidth chirp signal now enable spatiotemporal resolutions of 37.5 m and 50 s. We have applied these new capabilities for observations of Kelvin‐Helmholtz instability (KHI) dynamics in the low‐latitude ionosphere E region.
