User evaluation of detector performance in clinical photon‐counting and energy‐integrating CT scanners using DICOM images

open access: yesMedical Physics, Volume 52, Issue 10, October 2025.
Abstract Background Clinical users have a critical need to routinely assess the performance of photon‐counting detectors (PCDs) in PCD‐CT scanners. Such assessments provide insights into detector characteristics, support protocol optimization, and inform decisions on future scanner acquisitions.

Reentrant phase transitions and van der Waals behaviour for hairy black holes

open access: yes, 2015
We study the extended phase space thermodynamics for hairy AdS black hole solutions to Einstein-Maxwell-$\Lambda$ theory conformally coupled to a scalar field in five dimensions.

Woodward and Hoffmann on Secondary Orbital Interactions. How to Make a Fine Two‐Course Meal from Leftovers**

open access: yesThe Chemical Record, Volume 25, Issue 9, September 2025.
In February through April 1965, Hoffmann devised several MO tools to explain the regiochemistry of the Diels‐Alder and the preference of the Cope reaction to proceed by the chair rather than boat orientations, when both were possible. The secret lay in secondary orbital interactions that were revealed through qualitative perturbation theory.

Hardware Security in the Connected World

open access: yesWIREs Data Mining and Knowledge Discovery, Volume 15, Issue 3, September 2025.
Depicts the components covered in the article. ABSTRACT The rapid proliferation of the Internet of Things (IoT) has integrated billions of smart devices into our daily lives, generating and exchanging vast amounts of critical data. While this connectivity offers significant benefits, it also introduces numerous security vulnerabilities.

Exploring Advectable Latent Representations for Droplet Size Distributions With Physics‐Informed Autoencoders

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 9, September 2025.
Abstract Investigating the role of clouds and precipitation in the Earth system necessitates microphysical schemes capable of accurately describing the evolution of hydrometeor particle size distribution (PSD), while maintaining low computational costs implementable in atmospheric models.

Quantum Gates and Memory using Microwave Dressed States

open access: yes, 2011
Trapped atomic ions have been successfully used for demonstrating basic elements of universal quantum information processing (QIP). Nevertheless, scaling up of these methods and techniques to achieve large scale universal QIP, or more specialized quantum

G$G$‐typical Witt vectors with coefficients and the norm

open access: yesJournal of Topology, Volume 18, Issue 3, September 2025.
Abstract For a profinite group G$G$ we describe an abelian group WG(R;M)$W_G(R; M)$ of G$G$‐typical Witt vectors with coefficients in an R$R$‐module M$M$ (where R$R$ is a commutative ring). This simultaneously generalises the ring WG(R)$W_G(R)$ of Dress and Siebeneicher and the Witt vectors with coefficients W(R;M)$W(R; M)$ of Dotto, Krause, Nikolaus ...

A quasi-analytical modal approach for computing Casimir interactions in periodic nanostructures

open access: yes, 2012
We present an almost fully analytical technique for computing Casimir interactions between periodic lamellar gratings based on a modal approach. Our method improves on previous work on Casimir modal approaches for nanostructures by using the exact form ...

Agglomerative Algebras [PDF]

open access: yes, 2018
This paper investigates a generalization of Boolean algebras which I call agglomerative algebras. It also outlines two conceptions of propositions according to which they form an agglomerative algebra but not a Boolean algebra with respect to conjunction
