Anomaly interplay in U(2) gauge theories
Abstract: We discuss anomaly cancellation in U(2) gauge theories in four dimensions. For a U(2) gauge theory defined with a spin structure, the vanishing of the bordism group Ω5Spin (BU(2)) implies that there can be no global...
How important is the financial sector to price indices in an inflation targeting regime? An empirical analysis of the UK and the US
This paper investigates whether there are benefits in terms of higher economic stability from incorporating stock prices into the price index targeted by the central banks. It also looks into the question of whether central...

Anomaly interplay in U(2) gauge theories
We discuss anomaly cancellation in $U(2)$ gauge theories in four dimensions.
For a $U(2)$ gauge theory defined with a spin structure, the vanishing of the
bordism group $\Omega_5^{\text{Spin}}(BU(2))$ implies that there can be...
Focus U-Net
BACKGROUND: Colonoscopy remains the gold-standard screening for colorectal cancer. However, significant miss rates for polyps have been reported, particularly when there are multiple small adenomas. This presents an opportunity...

Threshold cointegration and the short-run dynamics of twin deficit hypothesis in African countries
This paper examines the relationship between the fiscal deficit and the current account deficit using the threshold cointegration approach of Hansen and Seo (2002). Using quarterly data for nine African countries for the...

Preparation, morphology and sonication time dependence of silver nanoparticles in amphiphilic block copolymers of PEO with polystyrene or PMMA
Imad Ud-Din, Mohsan Nawaz, Gareth Price, Musa Kaleem Baloch, Masroor Ahmad Bangesh, Wajid Rehman, Hameed Ullah, Saeed Ahmad
Sep 01, 2017
Composite materials comprising arrays of silver nanoparticles in amphiphilic copolymers have been prepared by sonochemically enhanced borohydride reduction of precursor silver nitrate (AgNO3). The precursor was incorporated into...
The U-shape of income inequality over the 20th century
Andreas Schaefer
Apr 30, 2021
We propose an overlapping generations model with three social classes to investigate the effects of higher education on the evolution of inequality. Initially, no social class invests in higher education and inequality is driven...

Geometric general solution to the U(1) anomaly equations
Abstract: Costa et al. [Phys. Rev. Lett.123 (2019) 151601] recently gave a general solution to the anomaly equations for n charges in a U(1) gauge theory. ‘Primitive’ solutions of chiral fermion charges were parameterised and it...
Semantic Segmentation of Hippocampal Subregions With U-Net Architecture
The Automatic semantic segmentation of the hippocampus is an important area of research in which several convolutional neural networks (CNN) models have been used to detect the hippocampus from whole cerebral MRI. In this paper...

Sep 14, 2018
Self-assembled hybrid perovskite quantum wells have attracted attention due to their tunable emission properties, ease of fabrication and device integration. However, the dynamics of excitons in these materials, especially how...
High-Throughput Electronic Structures and Ferroelectric Interfaces of HfO<inf>2</inf> by GGA+U(d,p) Calculations
The electronic structure, vacancy symmetry, defect levels, ferroelectric phases, and interface properties of HfO2 are studied using a GGA + U(d,p) approach, a simplified version of the ACBN0 method. Introducing an on‐site...
