A Change of Variables to the Dual and Factorization of Composite Anomalous Jacobians [PDF]

open access: yes, 1995
Changes of variables giving the dual model are constructed explicitly for sigma-models without isotropy. In particular, the jacobian is calculated to give the known results.

Flavour in supersymmetry: horizontal symmetries or wave function renormalisation [PDF]

open access: yes, 2010
We compare theoretical and experimental predictions of two main classes of models addressing fermion mass hierarchies and flavour changing neutral currents (FCNC) effects in supersymmetry: Froggatt-Nielsen (FN) U(1) gauged flavour models and Nelson ...

Are the anomalous vertebral arteries more hypoplastic?: retrospective linear mixed model approach

open access: yesBMC Neurology, 2017
Background Small or hypoplastic vertebral artery (VA) is one of the risk factor for posterior circulation stroke. We assess whether various types of VA anomaly contribute to its diameter.

Weak magnetic anomaly signal detection based on the entropy of mixed differential signal

open access: yesAIP Advances, 2021
Magnetic anomaly detection is of great significance in geological exploration and underwater target detection. However, the magnetic anomaly signal is not easy to be detected because of its weakness relative to the magnetic environmental noise, and the ...

Yukawa Textures and Anomaly Mediated Supersymmetry Breaking [PDF]

open access: yes, 2003
We present a detailed analysis of how a mixed-anomaly-free U(1) symmetry can be used to both resolve the slepton mass problem associated with Anomaly Mediated Supersymmetry Breaking and generate the fermion mass hierarchy via the Froggatt-Nielsen ...

Role of size and risk effects in value anomaly: Evidence from the Indian stock market

open access: yesCogent Economics & Finance, 2020
Portfolios of companies with high book-to-market (BTM) ratio (low Price-To-Book (PB) ratios, Value firms) outperform those with companies with low BTM ratio (high PB ratios, Growth firms). In literature, this is known as the Value Anomaly.

Compressed Anomaly Detection with Multiple Mixed Observations [PDF]

open access: green, 2018
We consider a collection of independent random variables that are identically distributed, except for a small subset which follows a different, anomalous distribution. We study the problem of detecting which random variables in the collection are governed by the anomalous distribution. Recent work proposes to solve this problem by conducting hypothesis

The SO(N) principal chiral field on a half-line [PDF]

open access: yes, 1999
We investigate the integrability of the SO(N) principal chiral model on a half-line, and find that mixed Dirichlet/Neumann boundary conditions (as well as pure Dirichlet or Neumann) lead to infinitely many conserved charges classically in involution.

Surgical repair of an obstructed mixed‐type total anomalous pulmonary venous connection

open access: yesClinical Case Reports, 2022
Total anomalous pulmonary venous connection is a rare congenital anomaly and has four anatomical subtypes of which the mixed type represents diagnostic and therapeutic challenge. When associated with obstruction, however, urgent surgical repair is needed.

Developing a perinatal palliative care service package for women with fetal anomaly diagnosis: protocol for mixed methods study

open access: yesReproductive Health, 2020
Background Diagnosis of perinatal anomalies is a stressful experience that can negatively affect mothers, families, health-care systems, and societies. Perinatal palliative care (PPC) is a new development in maternity services which focuses on emotional,
