Does Women’s Political Empowerment Matter for Income Inequality?

This study investigates the relationship between women’s political empowerment and income inequality in a global sample of 142 countries from 1990 to 2019. Employing a combination of machine learning techniques with an instrumental variable panel data approach, the analysis revea...

Dissonance in focus

Research Statement Research Background This practice-led research in jazz improvisation builds on my previous work on Melodic Tension Balancing, which explored hybrid scales to apply dissonances in improvised melodies. Expanding on this, the project examines the relationship betw...

Rethinking mental representation through the epistemology of modeling

The problems associated with classical symbolism need not entail abandoning representationalism. While representational theories of mind have been widely challenged by embodied and action-oriented approaches, representationalism remains alive and well in empirical research on hig...

All ways fire she gives

Research Statement Research Background All ways fire she gives is a poetic essay by Dr Jo Pollitt created as an invited response to Amanda Bells work in the John Stringer Prize, 2022 and published by Westerly. Developed through embodied, place-based writing, the essay engages wit...

MKUFT — A Relational Architecture for Physical Law and Cross-Scale Dynamics

MKUFT is an evolving research programme for analysing how possibility, relational constraint, physical dynamics, measurement, history, and scale-specific description fit together. This publication presents the current principal MKUFT architecture: a typed S–I–P–O framework in whi...

Affine Galois Realizations from Real Quadratic Units: Kummer Defects, Composita, and Radical Lattices

This preprint studies explicit Galois extensions arising from radicals of units in real quadratic fields. Let F/ℚ be a real quadratic field, let ε ∈ O_F× be a nonrational unit, and let ℓ ≥ 2. The associated trace–norm polynomial is Qε,ℓ(x) = (x^ℓ − ε)(x^ℓ − ε̄), where ε̄ denotes...

Galois Groups of Powered Quadratic Unit Polynomials: Real Kummer Structure and Imaginary Cyclotomic Classification

This preprint develops a general Galois-theoretic and arithmetic theory for power-compositional polynomials attached to quadratic units. Let F/ℚ be a quadratic field, let ε ∈ O_F× be a nonrational quadratic unit with conjugate ε̄, and let ℓ ≥ 2. The central family is Qε,ℓ(x) = (x...

Galois Groups of Powered Golden Ratio Polynomials: The Splitting Field of x^{2ℓ} - x^ℓ - 1

This preprint gives a complete arithmetic and Galois-theoretic analysis of the powered golden-ratio polynomial family Pℓ(x) = x^(2ℓ) − x^ℓ − 1, ℓ ≥ 2, whose roots are controlled by ℓ-th roots of the golden ratio φ = (1 + √5)/2 and its conjugate −φ⁻¹. For every integer ℓ ≥ 2, the...

Testing electron–photon exchange–correlation functional performance for many-electron systems under weak and strong light–matter coupling

We present results for a photon-free exchange–correlation functional within the local density approximation (pxcLDA) for quantum electrodynamics density functional theory (QEDFT), which efficiently describes the electron density of many-electron systems across weak to strong ligh...

Maps Preserving the Sum-to-Difference Ratio

For a field F, what are all functions f:F→F that satisfy the functional equation f((x+y)/(x−y))=(f(x)+f(y))/(f(x)−f(y)) for all x≠y in F? We solve this problem for the fields Q,R, and a class of its subfields that includes the real constructible numbers, the real algebraic number...

Pinwheel Scheduling with Real Periods

For a sequence of tasks, each with a positive integer period, the pinwheel scheduling problem involves finding a valid schedule in the sense that the schedule performs one task per day and each task is performed at least once every consecutive days of its period. It had been conj...

Stromme syndrome presenting with classic microcephaly and apple-peel intestinal atresia in a neonate: a genetically confirmed case report

<title>Abstract</title> <bold>Background:</bold> Stromme syndrome is an exceptionally rare autosomal recessive ciliopathy caused by biallelic pathogenic variants in the <italic>CENPF</italic> gene. It is classically characterized by microcephaly and apple-peel type intestinal atr...

Bias Testing and Mitigation in Black Box LLMs using Metamorphic Relations

The widespread deployment of Large Language Models (LLMs) has intensified concerns about subtle social biases embedded in their outputs. Existing guardrails often fail when faced with indirect or contextually complex bias-inducing prompts. To address these limitations, we propose...

PD-1 regulates CD4+ T cell-mediated CD8+ T cell responses in the brain to balance viral control and neuroinflammation

Abstract Programmed cell death protein 1 (PD-1) is expressed by T cells during progressive multifocal leukoencephalopathy (PML), a life-threatening brain disease caused by the human-only JC polyomavirus. Why PD-1 blockade finds variable success in PML patients is unclear. Brain C...

Reconstitution of glycan-driven MHC-I recycling reveals calreticulin as mediator between TAPBPR and tapasin

Abstract Protein folding in the endoplasmic reticulum (ER) is essential for about one-third of the mammalian proteome. N-linked glycosylation and subsequent glycan remodeling barcodes glycoproteins during their maturation in the ER. Major histocompatibility complex class I (MHC I...

Development of a chemometric platform for mid-infrared fermentation monitoring

<title>Abstract</title> Industrial bioprocess development still depends heavily on off-line analytics such as HPLC, which, while accurate, are slow and limit real-time decision-making. Process Analytical Technologies (PAT) can overcome this barrier, with mid-infrared spectroscopy...

Detection of spiking motifs of arbitrary length in neural activity using bounded synaptic delays

In the context of spiking neural networks, the temporal coding hypothesis is increasingly preferred over the rate coding hypothesis due to its advantages in processing speed and energy efficiency. In temporal coding, synaptic delays are crucial for processing signals with precise...

MIR17HG Expression Is Transcriptionally Regulated by PAX3::FOXO1 and MYCN and is Necessary for Oncogenic Activity in Fusion-Positive Rhabdomyosarcoma

Alveolar rhabdomyosarcoma (RMS), an aggressive pediatric soft tissue cancer, is driven by the oncogenic fusion transcription factor PAX3::FOXO1 (P3F) or PAX7::FOXO1. In a subset of fusion-positive (FP)-RMS cases, amplification of the MIR17HG locus leads to overexpression of the m...
