Analysis of millimetre wave polarization diverse multiple input multiple output capacity
(2015)Millimetre-waves offer the possibility of wide bandwidth and consequently high data rate for wireless communications. For both uni- and dual-polarized systems, signals sent over a link may suffer severe degradation due to ... -
Analytical model of reactive transport processes with spatially variable coefficients
(2015)Analytical solutions of partial differential equation (PDE) models describing reactive transport phenomena in saturated porous media are often used as screening tools to provide insight into contaminant fate and transport ... -
Ants determine their next move at rest
(2016)To find useful work to do for their colony, individual eusocial animals have to move, somehow staying attentive to relevant social information. Recent research on individualTemnothorax albipennis ants moving inside their ... -
Applied Discrete Structures
(University of Massachusetts Lowell, 2013)Chapter 1: Set Theory. Chapter 2: Combinatorics. Chapter 3: Logic. Chapter 4: More on Sets. Chapter 5: Introduction to Matrix Algebra. Chapter 6: Relations and Graphs. Chapter 7: Functions. Chapter 8: Recursion and Recurrence ... -
Approximate series solution of multi-dimensional, time fractional-order (heat-like) diffusion equations using FRDTM
(2015)The main goal of this paper is to present a new approximate series solution of the multi-dimensional (heat-like) diffusion equation with time-fractional derivative in Caputo form using a semi-analytical approach: ... -
Are genes faster than crabs?
(2014)Biological invasions offer unique opportunities to investigate evolutionary dynamics at the peripheries of expanding pop-ulations. Here, we examine genetic patterns associated with admixture between two distinct invasive ... -
Are migratory behaviours of bats socially transmitted?
(2016)To migrate, animals rely on endogenous, genetically inherited programmes, or socially transmitted information about routes and behaviours, or a combination of the two. In long-lived animals with extended parental care, as ... -
Are there statistical links between the direction of European weather systems and ENSO, the solar cycle or stratospheric aerosols?
(The Royal Society, 2016)The Hess Brezowsky Großwetterlagen (HBGWL) European weather classification system, accumulated over a long period (more than 130 years), provides a rare opportunity to examine the impact of various factors on regional ... -
Aremicrobes fundamentally different than macroorganisms?
(2015)This study reveals extensive phenotypic convergence based on the non-monophyly of genera and morphospecies of testate (shelled) amoebae. Using two independent markers, small subunit ribosomal DNA (ssu-rDNA) and mitochondrial ... -

(2016)To migrate, animals rely on endogenous, genetically inherited programmes, or socially transmitted information about routes and behaviours, or a combination of the two. In long-lived animals with extended parental care, as ... -
Arithmetic for College Students
(Opentextbookstore, 2014)This book is a course on arithmetic designed for college students. It covers whole numbers, fractions, decimals, percents, ratios and proportions, measurement, and integers. Geometry and statistics are integrated throughout ... -
Articulated Hand Tracking by ICA-based Hand Model and Multiple Cameras
(INTECH Open Access Publisher, 2007)In this chapter, we proposed three new approaches, the ICA-based hand model, articulated hand motion tracking by multiple cameras, and Particle filtering with prediction. The ICA-based hand model is the ICA-based representation ... -
Artificial light onwater attracts turtle hatchlings during their near shore transit
(2016)We examined the effect of artificial light on the near shore trajectories of turtle hatchlings dispersing from natal beaches. Green turtle (Chelonia mydas) hatchlings were tagged with miniature acoustic transmitters and ... -
Assessing costs of carrying geolocators using feather corticosterone in two species of aerial insectivore
(2015)Despite benefits of using light-sensitive geolocators to track animal movements and describe patterns of migratory connectivity, concerns have been raised about negative effects of these devices, particularly in small ... -
Assessing recognition memory using confidence ratings and response times
(2016)Classification of stimuli into categories (such as ‘old’ and ‘new’ in tests of recognition memory or ‘present’ versus ‘absent’ in signal detection tasks) requires the mapping of internal signals to discrete responses. ... -
Asymptotic formulae for the Lommel and Bessel functions and their derivatives
(The Royal Society, 2014)We derive new approximate representations of the Lommel functions in terms of the Scorer function and approximate representations of the first derivative of the Lommel functions in terms of the derivative of the Scorer ... -
Ataleoftwo seas: contrasting patterns of population structure in the small-spotted catshark across Europe
(The Royal Society, 2014)Elasmobranchs represent important components of marine ecosystems, but they can be vulnerable to overexploitation. This has driven investigations into the population genetic structure of large-bodied pelagic sharks, but ... -
Atomic scalemodelling of hexagonal structured metallic fission product alloys
(2015)Noble metal particles in the Mo-Pd-Rh-Ru-Tc system have been simulated on the atomic scale using density functional theory techniques for the first time. The composition and behaviour of the epsilon phases are consistent ... -
Attack risk for butterflies changes with eyespot number and size
(2016)Butterfly eyespots are known to function in predator deflection and predator intimidation, but it is still unclear what factors cause eyespots to serve one function over the other. Both functions have been demonstrated in ... -
Attenuation of species abundance distributions by sampling
(2015)Quantifying biodiversity aspects such as species presence absence, richness and abundance is an important challenge to answer scientific and resource management questions. In practice, biodiversity can only be assessed ...
