The Distribution of Cross Sectional Momentum Returns When Underlying Asset Returns Are Student’s t Distributed
In Kwon and Satchell (2018), a theoretical framework was introduced to investigate the distributional properties of the cross-sectional momentum returns under the assumption that the vector of asset returns over the...
Avoiding artefacts in MicroCT imaging of Collagen Scaffolds
X-ray micro-computed tomography (µ-CT) can be used to provide both qualitative and quantitative information on the structure of three-dimensional (3D) bioactive scaffolds. When performed in a dry state, µ-CT accurately reflects...
Cost efficiency and board composition under different takaful insurance business models
This study examines the link between cost efficiency and board composition in non-life takaful insurance firms operating in 17 Islamic countries using panel data for 2004-2007. Nonparametric data envelopment analysis (DEA) is...
Bioactive conformable hydrogel-carbonated hydroxyapatite nanocomposite coatings on Ti-6Al-4V substrates
A series of nanocomposite coatings was produced, comprising a hydrogel polymer, poly(2-hydroxyethyl methacrylate)/poly(ε-caprolactone) (PHEMA/PCL) matrix with nanoscale carbonated hydroxyapatite (nCHA) filler particles. The...
Age-related endothelial dysfunction in human skeletal muscle feed arteries
Net load‐displacement estimation in soil‐nailing pullout tests
Soil-nails are used to stabilise a soil mass by exploiting the resistance generated by the skin friction between the ground and grout and the tensile stiffness of the reinforcing material. A load–displacement curve is obtained...
Validation of the Apple Watch for Estimating Moderate-to-Vigorous Physical Activity and Activity Energy Expenditure in School-Aged Children
The Apple Watch is one of the most popular wearable devices designed to monitor physical activity (PA). However, it is currently unknown whether the Apple Watch accurately estimates children’s free-living PA. Therefore, this...
Induced Birefringence in 3D Printing
David Michael Roper, Kyung‐Ah Kwon, Luke Peter Malone, Serena Michelle Best, Ruth Elizabeth Cameron
May 26, 2022
Abstract: This paper presents a novel method to spatially vary the intra‐layer birefringence of Fused Filament Fabricated (FFF) parts by controlling chain alignment during extrusion along individual rasters. The role of print...

The 3D printing of freestanding PLLA thin layers and improving first layer consistency through the introduction of sacrificial PVA
Fused filament fabrication (FFF) is an inexpensive way of producing objects through a programmed layer-by-layer deposition. For multi-layer, macro-scaled prints, acceptable printing is achieved provided, amongst other...
Inter-Device Agreement between Fitbit Flex 1 and 2 for Assessing Sedentary Behavior and Physical Activity.
This study examined the inter-model agreement between the Fitbit Flex (FF) and FF2 in estimating sedentary behavior (SED) and physical activity (PA) during a free-living condition. 33 healthy adults wore the FF and FF2 on...
Review of digital printing technologies for electronic materials
Kye-Si Kwon, Md Khalilur Rahman, Thanh Huy Phung, Stephen D Hoath, Sunho Jeong, Jang Sub Kim
Dec 22, 2020
Abstract: Direct printing methods have been used as manufacturing tools for printed electronics applications due to their cost effectiveness. In this review, the piezo-driven inkjet is discussed in detail since it is a mature...
Sleep reactivation did not boost suppression-induced forgetting.
Eitan Schechtman, Anna Lampe, Brianna J Wilson, Eunbi Kwon, Michael C Anderson, Ken A Paller
Mar 12, 2021
Sleep's role in memory consolidation is widely acknowledged, but its role in weakening memories is still debated. Memory weakening is evolutionary beneficial and makes an integral contribution to cognition. We sought evidence on...

Dark Matter Deficient Galaxies Produced via High-velocity Galaxy Collisions in High-resolution Numerical Simulations
Abstract
The recent discovery of diffuse dwarf galaxies that are deficient in dark matter appears to challenge the current paradigm of structure formation in our universe. We...
High-speed camera characterization of voluntary eye blinking kinematics.
Kyung-Ah Kwon, Rebecca J Shipley, Mohan Edirisinghe, Daniel G Ezra, Geoff Rose, Serena M Best, Ruth E Cameron
Sep 25, 2013
Blinking is vital to maintain the integrity of the ocular surface and its characteristics such as blink duration and speed can vary significantly, depending on the health of the eyes. The blink is so rapid that special...
