3D Printing a Clinically Available Solution From Plaster‐Based Positives in Superficial Radiation Therapy

Journal of Medical Radiation Sciences, EarlyView.
This study compares two techniques for creating lead shielding masks to replace the current process for superficial/orthovoltage facial radiotherapy: Plaster Cast Positive Mould (PCPM), CT Scanned 3D Print (CT3DP), and Optical Scan 3D Print (OS3DP). CT3DP was found to be more accurate and preferred over OS3DP.

A Unified Model for Shock Interaction and γ-Ray Emission in Classical Novae

The Astrophysical Journal
We present a parameterized (“toy”) model for shock interaction and γ -ray emission in classical novae, in which a white dwarf envelope of mass M _env is removed over a timescale τ (proportional to the nova speed class, t _2 ) in an outflow that ...

Iron Fertilization of Soybean Genotypes Differing in Iron Use Efficiency Under Alkaline Conditions: Implications for Yield and Seed Nutritional Quality

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Soybean, a nutritionally important protein‐ and oil‐rich legume, is highly sensitive to iron (Fe) deficiency under alkaline conditions, where reduced Fe availability limits growth, yield, and seed quality. Effective biofortification therefore requires increasing seed Fe while reducing phytate that restricts Fe bioavailability.

Low-metallicity Nova Explosions: A Site for Weak rp-process Nucleosynthesis

The Astrophysical Journal
Classical novae are common cataclysmic events involving a binary system of a white dwarf and a main-sequence or red giant companion star. In metal-poor environments, these explosions produce ejecta differently from their solar counterparts due to the ...

The Bazaar as a Model for Knowledge Work

Knowledge and Process Management, EarlyView.
ABSTRACT This paper presents fieldwork that extends existing metaphors of knowledge work as a process shaped by hierarchical or market forces. A qualitative, ethnographic study of six knowledge‐intensive businesses in two countries identifies striking parallels with the Middle Eastern bazaar in contrast to Western impersonal markets and hierarchies. We

A Severity‐Agnostic Atrophy Pattern in Spinocerebellar Ataxia Type 3: Volumetrics from ENIGMA‐Ataxia

Movement Disorders, EarlyView.
Background Spinocerebellar ataxia type 3 (SCA3) is a rare, inherited neurodegenerative disease characterized by progressive loss of motor coordination. Objectives We undertook a multisite magnetic resonance imaging study to profile the spatial spread of atrophy across the brain, determine whether atrophy preferentially maps onto specific functional ...

Exploring Asymptotic Normality in Multinomial Models

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Among the methods for analyzing categorical outcomes, the multinomial model offers a robust framework for examining the dependence between a multi‐category response variable and a set of explanatory variables. Its flexibility, versatility, and broad applicability across diverse fields make it a valuable tool, as it does not impose strict ...

Nordgren PINNs to VQE: Advancing Hydraulic Fracturing Simulations in Shale Reservoirs

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study advances hydraulic fracturing simulations in shale reservoirs using two computational paradigms, Physics‐Informed Neural Networks (PINNs) and the Variational Quantum Eigensolver (VQE). PINNs were employed to solve Nordgren's equation, which governs fracture width evolution, by embedding physical laws into the neural network ...
