Simulation of between repeat variability in real time PCR reactions [PDF]

open access: yes, 2012
While many decisions rely on real time quantitative PCR (qPCR) analysis few attempts have hitherto been made to quantify bounds of precision accounting for the various sources of variation involved in the measurement process.

Optimal control with the effects of ivermectin and live stock availability on malaria transmission

open access: yesJournal of Nigerian Society of Physical Sciences
Malaria remains a global threat and the conventional methods used for combating the disease leave out mosquitoes that feed outdoors. This study addresses the challenge posed by such mosquitoes based on a tool called ivermectin drug which is lethal to ...

Bifurcation sets arising from non-integer base expansions [PDF]

open access: yes, 2018
Given a positive integer $M$ and $q\in(1,M+1]$, let $\mathcal U_q$ be the set of $x\in[0, M/(q-1)]$ having a unique $q$-expansion: there exists a unique sequence $(x_i)=x_1x_2\ldots$ with each $x_i\in\{0,1,\ldots, M\}$ such that \[ x=\frac{x_1}{q ...

FIFTH-ORDER A(α)-STABLE BLOCK HYBRID ADAMS-MOULTON METHOD FOR SOLUTIONS OF PREDATOR-PREY AND LORENZ SYSTEMS

open access: yesIntermaths
Problems associated with nonlinearity in predator-prey and chaotic nature embedded in Lorenz system place a significant challenge on numerical methods for their solutions. Some numerical methods may become unstable as step size increases. In this study,

ENSO Amplitude Asymmetry in Met Office Hadley Centre Climate Models

open access: yesFrontiers in Climate, 2021
Long climate simulations with the Met Office Hadley Centre General Circulation Model show weak El Niño-Southern Oscillation (ENSO) amplitude asymmetry between El Niño and La Niña phases compared with observations.

Non-proper helicoid-like limits of closed minimal surfaces in 3-manifolds [PDF]

open access: yes, 2008
We show that there exists a metric with positive scalar curvature on S2xS1 and a sequence of embedded minimal cylinders that converges to a minimal lamination that, in a neighborhood of a strictly stable 2-sphere, is smooth except at two helicoid-like ...

Dynamics and stationary configurations of heterogeneous foams

open access: yes, 2018
We consider the variational foam model, where the goal is to minimize the total surface area of a collection of bubbles subject to the constraint that the volume of each bubble is prescribed.

Analyzing the causes of alpine meadow degradation and the efficiency of restoration strategies through a mathematical modelling exercise

open access: yesMathematical Biosciences and Engineering, 2018
As an important ecosystem, alpine meadow in China has been degraded severely over the past few decades. In order to restore degraded alpine meadows efficiently, the underlying causes of alpine meadow degradation should be identified and the efficiency of

On the Topological Characterization of Near Force-Free Magnetic Fields, and the work of late-onset visually-impaired Topologists [PDF]

open access: yes, 2015
The Giroux correspondence and the notion of a near force-free magnetic field are used to topologically characterize near force-free magnetic fields which describe a variety of physical processes, including plasma equilibrium.

Synchrotron Radiation for Quantum Technology

open access: yesAdvanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.
