The K41 Spectrum as the Unique Variational Minimiser of a Scale-Resolved Free Energy

This preprint is Paper A in the turbulence split of the Functional Stability Theory programme. It isolates the unconditional variational result: the Kolmogorov K41 energy spectrum is the unique global minimiser of a scale-resolved free-energy functional under joint minimisation o...

A Late Iron Age and Romano-British Farmstead at Cedars Park, Stowmarket, Suffolk

Excavations by Archaeological Solutions Ltd, on a south-facing clay hillside above the River Gipping in Mid Suffolk, revealed the remains of a farmstead dating from the late Iron Age to the mid 4th century AD.The late Iron Age (Phase 1) settlement comprised two ditched enclosures...

Resilience and Protective Factors for Mental Health among Indigenous Youth in Canada: A Scoping Review

Abstract Indigenous youth’s inherent strength and resilience play a vital role in their well-being and mental health. Protective factors, closely linked to resilience, spanning individual, family, and community levels reinforce positive mental health outcomes. The purpose of the...

Conditional aggregation-based Choquet integral on discrete space

Abstract We derive computational formulas for a generalization of the Choquet integral based on the novel survival function introduced by Boczek et al. (2021). We describe sufficient and necessary conditions under which novel survival functions based on different parameters coinc...

Global harms, local profits: How the uneven costs of natural disasters affect support for green political platforms

Abstract Large‐scale fires are becoming increasingly common due to climate change. While conventional wisdom suggests that firsthand experiences with natural disasters foster green coalitions by raising awareness of environmental degradation, we propose an alternative view: Natur...

Encapsulation of AAVs into Protein Vault Nanoparticles as a Novel Solution to Gene Therapy’s Neutralizing Antibody Problem

Abstract Although adeno-associated virus (AAV) has enjoyed enormous success as a delivery modality for gene therapy, it suffers from high prevalence of preexisting neutralizing antibodies in human populations, limiting who can receive potentially life-saving treatments. As a nove...

Efficient Graph State Generation in Linear Optics

Graph states are central resources for quantum information processing, supporting applications in computation, communication, and error correction. In photonic systems, they are typically assembled from smaller entangled states using probabilistic fusion gates, which demand many...

Closed-form solutions for rigid transformations between heterogeneous groups of noisy geometric primitives

Abstract Computing the transformation between noisy collections of geometric primitives is a classic problem in three-dimensional computer vision and geometric computing. In this paper, we consider minimum sets of noisy objects and provide closed-form formulae to compute the Eucl...

Stereotactic Body Radiotherapy vs Moderately Hypofractionated IMRT for Localized Intermediate-Risk Prostate Cancer

Importance The treatment of prostate cancer with radiotherapy is evolving. How quickly radiotherapy can be delivered, and the relative risks and benefits of such a treatment, is of significant public interest. Objective To determine whether stereotactic body radiotherapy (SBRT) w...

Review of Clifford algebra-based AI methods in signal analysis

Abstract Hypercomplex number systems, such as complex numbers and quaternions, have found many uses in the area of signal analysis. Clifford algebras, along with the embedding of (usually) a real vector space, can be used to represent some of the commonly used hypercomplex algebr...

Operational astronaut and payload radiation exposure during the Axiom-4 spaceflight measured by RadNano Infinity Astronaut Dosimeters

Abstract Accurate characterisation of the radiation environment is essential for assessing astronaut exposure and supporting space biomedical research during human spaceflights. Here we present distributed radiation measurements obtained during the Axiom-4 mission using ten compa...

Curvilinear coordinate systems for 3D design: building cyclidic nets with conformal geometric algebra

Abstract We introduce various parametric techniques to construct and manipulate triply orthogonal curvilinear lattices. Using principal contact tangent elements and the rationalization of spheres through conformal transformations, we detail their constraints and provide an invers...

Overview of W. K. Clifford's geometric algebras

Abstract This paper presents the very basics of W. K. Clifford's geometric algebras (GAs), which encompass Euclidean GA, as well as of the most important ones for engineering, graphics, virtual reality, signal processing, encryption, neural networks (deep learning), crystallograp...

Geometric algebra integral transforms and their applications

Abstract In geometric algebra (GA), real and complex integral transforms (Fourier transforms, linear canonical transforms (LCTs), wavelets, fractional Fourier transforms, special affine Fourier transforms, etc.) can be generalized to holistic higher-dimensional quaternionic, octo...

Merits of geometric algebra applied to cryptography and machine learning

Abstract We present Clifford fully homomorphic encryption (FHE), the first ring-learning with errors (RLWE)-based FHE scheme with native support for all Clifford algebra operations, enabling privacy-preserving computation on geometric data. Unlike conventional FHE schemes that fl...

Geometric algebra: an overview about different implementation representations and memory requirements

Abstract Several implementations of geometric algebra are available, and many have been approved in the past and can be found in various software codes. For low-dimensional algebras, representations as a sum of basis blades are typically the most suitable. However, isomorphic or...

One algebra for all: geometric algebra methods for neurosymbolic XR scene authoring, animation and neural rendering

Abstract This position paper delves into the transformative role of geometric algebra (GA) in advancing specific areas of computer graphics (CG) and extended reality (XR), particularly in character animation, rendering, rigging, neural rendering and generative artificial intellig...

Chemovaccination with a late-liver-stage antimalarial induces durable immunity against malaria

Plasmodium falciparum sporozoite vaccines, in which parasites are attenuated at the liver stage, provide high efficacy but require complex manufacture and intravenous administration of high sporozoite doses. We found that a single low-dose P. berghei sporozoite exposure (intraven...
