OBJECTIVE: The electroencephalogram (EEG) has been widely used in AD/HD research. The current study firstly aimed to replicate a recent trend related to EEG theta/beta ratio (TBR) in children and adolescents. Also, the study aimed to examine the value of resting EEG activity as biomarkers for executive function (EF) in participants with AD/HD. METHOD: Fifty-three participants with AD/HD and 37 healthy controls were recruited. Resting EEG was recorded with eyes closed. Participants with AD/HD additionally completed EF tasks via the Cambridge Neuropsychological Test Automated Battery. RESULTS: TBR did not differ between groups; however, TBR was positively correlated with inattentive symptoms …
The Translational Controlled Tumour Protein Tctp: Biological Functions And Regulation, Ulrich A. Bommer
The Translational Controlled Tumour Protein Tctp: Biological Functions And Regulation, Ulrich A. Bommer
Faculty of Science, Medicine and Health - Papers: part A
The Translational Controlled Tumour Protein TCTP (gene symbol TPT1, also called P21, P23, Q23, fortilin or histamine-releasing factor, HRF) is a highly conserved protein present in essentially all eukaryotic organisms and involved in many fundamental cell biological and disease processes. It was first discovered about 35 years ago, and it took an extended period of time for its multiple functions to be revealed, and even today we do not yet fully understand all the details. Having witnessed most of this history, in this chapter, I give a brief overview and review the current knowledge on the structure, biological functions, disease …

Given evidence that early executive functioning sets the stage for a broad range of subsequent outcomes, researchers have sought to identify ways to foster these cognitive capacities. The current series of studies sought to design, develop, and provide evidence for the efficacy of embedding cognitive activities in a commonplace activity-shared reading of a children's book. The book, Quincey Quokka's Quest, required children to control their thinking and behavior to help the story's main character through a series of obstacles. The first study investigated effects of reading with embedded cognitive activities in individual and group contexts on young children's executive functions …
Contraction Of Convex Surfaces By Nonsmooth Functions Of Curvature, Ben H. Andrews, James A. Mccoy
Contraction Of Convex Surfaces By Nonsmooth Functions Of Curvature, Ben H. Andrews, James A. Mccoy
Faculty of Engineering and Information Sciences - Papers: Part A
We consider the motion of convex surfaces with normal speed given by arbitrary strictly monotone, homogeneous degree one functions of the principal curvatures (with no further smoothness assumptions). We prove that such processes deform arbitrary uniformly convex initial surfaces to points in finite time, with spherical limiting shape. This result was known previously only for smooth speeds. The crucial new ingredient in the argument, used to prove convergence of the rescaled surfaces to a sphere without requiring smoothness of the speed, is a surprising hidden divergence form structure in the evolution of certain curvature quantities.

Political leaders increasingly perceive health as being crucial to achieving growth, development, equity and stability throughout the world. Health is now understood as a product of complex and dynamic relations generated by numerous determinants at different levels of governance. Governments need to take into account the impact of social, environmental and behavioural health determinants, including economic constraints, living conditions, demographic changes and unhealthy lifestyles in many of the World Health Organization (WHO) Member States. This understanding and increasing globalization means it is very timely to review the role of (global) public health in this changing societal and political environment.
Evaluation Of A Differentiation Model Of Preschoolers' Executive Functions, Steven J. Howard, Anthony D. Okely, Yvonne Ellis
Evaluation Of A Differentiation Model Of Preschoolers' Executive Functions, Steven J. Howard, Anthony D. Okely, Yvonne Ellis
Faculty of Social Sciences - Papers (Archive)
Despite the prominent role of executive functions in children's emerging competencies, there remains debate regarding the structure and development of executive functions. In an attempt to reconcile these discrepancies, a differentiation model of executive function development was evaluated in the early years using 6-month age groupings. Specifically, 281 preschoolers completed measures of working memory, inhibition, and shifting. Results contradicted suggestions that executive functions follow a single trajectory of progressive separation in childhood, instead suggesting that these functions may undergo a period of integration in the preschool years. These results highlight potential problems with current practices and theorizing in executive function …
Convexity Estimates For Surfaces Moving By Curvature Functions, Ben Andrews, Mat Langford, James A. Mccoy
Convexity Estimates For Surfaces Moving By Curvature Functions, Ben Andrews, Mat Langford, James A. Mccoy
Faculty of Engineering and Information Sciences - Papers: Part A
We consider the evolution of compact surfaces by fully nonlinear, parabolic curvature ows for which the normal speed is given by a smooth, degree one homogeneous function of the principal curvatures of the evolving surface. Under no further restrictions on the speed function, we prove that initial surfaces on which the speed is positive become weakly convex at a singularity of the flow. This generalises the corresponding result [26] of Huisken and Sinestrari for the mean curvature ow to the largest possible class of degree one homogeneous surface flows.
Motion By Mixed Volume Preserving Curvature Functions Near Spheres, David James Hartley
Motion By Mixed Volume Preserving Curvature Functions Near Spheres, David James Hartley
Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers
In this paper we investigate the flow of hypersurfaces by a class of symmetric functions of the principal curvatures with a mixed volume constraint. We consider compact hypersurfaces without boundary that can be written as a graph over a sphere. The linearisation of the resulting fully nonlinear PDE is used to prove a short-time existence theorem for hypersurfaces that are sufficiently close to a sphere and, using centre manifold analysis, the stability of the sphere as a stationary solution to the flow is determined. We will find that for initial hypersurfaces sufficiently close to a sphere, the flow will exist …

Convexity Estimates For Hypersurfaces Moving By Convex Curvature Functions, Ben Andrews, Mat Langford, James A. Mccoy
Faculty of Engineering and Information Sciences - Papers: Part A
We consider the evolution of compact hypersurfaces by fully non-linear, parabolic curvature ows for which the normal speed is given by a smooth, convex, degree one homoge- neous function of the principal curvatures. We prove that solution hypersurfaces on which the speed is initially positive become weakly convex at a singularity of the ow. The result extends the convexity estimate [HS99b] of Huisken and Sinestrari for the mean curvature ow to a large class of speeds, and leads to an analogous description of `type-II' singularities. We remark that many of the speeds considered are positive on larger cones than the …

A typical casein micelle contains thousands of casein molecules, most of which form thermodynamically stable complexes with nanoclusters of amorphous calcium phosphate. Like many other unfolded proteins, caseins have an actual or potential tendency to assemble into toxic amyloid fibrils, particularly at the high concentrations found in milk. Fibrils do not form in milk because an alternative aggregation pathway is followed that results in formation of the casein micelle. As a result of forming micelles, nutritious milk can be secreted and stored without causing either pathological calcification or amyloidosis of the mother's mammary tissue. The ability to sequester nanoclusters of …
Consensus On The Future Core Functions And Competency Requirements Of Public Health Nutritionists, Roger Hughes, Andrea Begley, Heather Yeatman
Consensus On The Future Core Functions And Competency Requirements Of Public Health Nutritionists, Roger Hughes, Andrea Begley, Heather Yeatman
Faculty of Science, Medicine and Health - Papers: part A
Competency standards provide the architecture for workforce development and serve to inform workforce preparation, continuing professional development and quality assurance via registration and credentialing systems. Developing consensus on competency requirements for the developing global public health nutrition workforce is therefore an important strategic initiative. This study aimed to assess the level of consensus amongst an international panel of public health nutrition leaders regarding the essential competencies required for effective public health nutrition practice.
Horadam Functions And Powers Of Irrationals, Martin W. Bunder
Horadam Functions And Powers Of Irrationals, Martin W. Bunder
Faculty of Engineering and Information Sciences - Papers: Part A
This paper generalizes a result of Gerdemann to show (with slight variations in some special cases) that, for any real number m and Horadam function Hn(A, B, P,Q), mHn(A, B, P, Q) = i=h k∑(t,Hn+i(A, B, P, Q)), for two consecutive values of n, if and only if, m= i=h k∑ (tiai)= i=h k∑ (t ibi) where a =(P+(P2-4Q) 1/2)/2 and b = (P-(P2-4Q) 1/2)/2. (Horadam functions are defined by: H 0(A, B, P, Q) = A, H1(A,B,P,Q) = B, Hn+1(A, B, P,Q) = PHn(A,B, P,Q)-QHn-1(A, B, P,Q).) Further generalizations to the solutions of arbitrary linear recurrence relations are also …

Risk-Adaptive Volumetric Modulated Arc Therapy Using Biological Objective Functions For Subvolume Boosting In Radiotherapy, Nicholas G. Hardcastle, Wolfgang Tome
Faculty of Engineering and Information Sciences - Papers: Part A
Simultaneous integrated boost (SIB) for prostate cancer allows increases in tumor control probability while respecting normal tissue dose constraints. Biological optimization functions that optimize based on treatment outcome can be used to create SIB prostate plans. This study investigates the feasibility of biologically optimized volumetric modulated arc therapy (VMAT) for SIB prostate radiotherapy. Methods. Five prostate cancer patients with diffusion-weighted MR images were selected for analysis. A two-step VMAT optimization was performed, which consisted of an initial biological optimization of a static gantry angle delivery followed by conversion of the static delivery to a single arc VMAT plan. A dosimetric …
Team Situation Awareness Measure Using Semantic Utility Functions For Supporting Dynamic Decision-Making, Jun Ma, Jie Lu, Guangquan Zhang
Team Situation Awareness Measure Using Semantic Utility Functions For Supporting Dynamic Decision-Making, Jun Ma, Jie Lu, Guangquan Zhang
Faculty of Engineering and Information Sciences - Papers: Part A
Team decision-making is a remarkable feature in a complex dynamic decision environment, which can be supported by team situation awareness. In this paper, a team situation awareness measure (TSAM) method using a semantic utility function is proposed. The semantic utility function is used to clarify the semantics of qualitative information expressed in linguistic terms. The individual and team situation awareness are treated as linguistic possibility distributions on the potential decisions in a dynamic decision environment. In the TSAM method, team situation awareness is generated through reasoning and aggregating individual situation awareness based on a multi-level hierarchy mental model of the …

The Dixmier Trace And Asymptotics Of Zeta Functions, Alan L. Carey, Adam C. Rennie, Aleksandr Sedaev, Fyodor A. Sukochev
Faculty of Engineering and Information Sciences - Papers: Part A
We obtain general theorems which enable the calculation of the Dixmier trace in terms of the asymptotics of the zeta function and of the trace of the heat semigroup. We prove our results in a general semi-finite von Neumann algebra. We find for p > 1 that the asymptotics of the zeta function determines an ideal strictly larger than Lp,∞ on which the Dixmier trace may be defined. We also establish stronger versions of other results on Dixmier traces and zeta functions.
