Quaternionic Hyperbolic Fenchel-Nielsen Coordinates
, 2018 Let $Sp(2,1)$ be the isometry group of the quaternionic hyperbolic plane ${{\bf H}_{\mathbb H}}^2$. An element $g$ in $Sp(2,1)$ is `hyperbolic' if it fixes exactly two points on the boundary of ${{\bf H}_{\mathbb H}}^2$.

BMC Primary Care, 2021 Background Patient access to primary healthcare (PHC) is the foundation of a strong healthcare system and healthy populations. Attachment to a regular PHC provider, a key to healthcare access, has seen a decline in some jurisdictions. This study explored

A system of dual quaternion matrix equations with its applications
, 2023 We employ the M-P inverses and ranks of quaternion matrices to establish the necessary and sufficient conditions for solving a system of the dual quaternion matrix equations $(AX, XC) = (B, D)$, along with providing an expression for its general solution.

Implications of incidental findings from lung screening for primary care: data from a UK pilot
npj Primary Care Respiratory Medicine, 2021 Regional lung cancer screening (LCS) is underway in England, involving a “lung health check” (LHC) and low-dose CT scan for those at high risk of cancer. Incidental findings from LHCs or CTs are usually referred to primary care.

Developing a Patient Safety Culture in Primary Dental Care
Primary Dental Journal, 2021 Patient safety should be at the heart of any healthcare service. Systems, teams, individuals and environments must work in tandem to strive for safety and quality. Research into patient safety in dentistry is still in the early stages.

Cokernels of random matrices satisfy the Cohen-Lenstra heuristics [PDF]
, 2013 Let A be an n by n random matrix with iid entries taken from the p-adic integers or Z/NZ. Then under mild non-degeneracy conditions the cokernel of A has a universal probability distribution.

L-structure least squares solutions of reduced biquaternion matrix equations with applications
, 2023 This paper presents a framework for computing the structure-constrained least squares solutions to the generalized reduced biquaternion matrix equations (RBMEs). The investigation focuses on three different matrix equations: a linear matrix equation with

New binary self-dual codes via a generalization of the four circulant construction [PDF]
, 2019 In this work, we generalize the four circulant construction for self-dual codes. By applying the constructions over the alphabets $\mathbb{F}_2$, $\mathbb{F}_2+u\mathbb{F}_2$, $\mathbb{F}_4+u\mathbb{F}_4$, we were able to obtain extremal binary self-dual
