Background Follow-up of HIV-exposed children for the delivery of prevention of mother-to-child transmission services and for early diagnosis and treatment of HIV infection is critical to their survival. Despite efforts, uptake of postnatal care for these children remains low in many subSaharan African countries. Methods A qualitative study was conducted in three provinces in Mozambique to identify motivators and barriers to improve uptake of and retention in HIV prevention, care and treatment services for HIV-exposed and HIV-infected children. Participant recommendations were also gathered. Individual interviews (n=79) and focus group discussions (n=32) were conducted with parents/caregivers, grandmothers, community leaders and health …

Two Species Competitive Model With The Allee Effect, Ann Brett, Mustafa Rs Kulenović

Mathematics Faculty Publications

We consider the following system of difference equations: [Mathematical equations cannot be displayed here, refer to PDF], where a, b, c, d are positive constants and x₀, y₀ ≥ 0 are initial conditions. This system has interesting dynamics and can have up to nine equilibrium points. The most complex and perhaps most interesting case is the case of nine equilibrium points, four of which are local attractors, four of which are saddle points, and one of which is a repeller. Using recent results of Kulenović and Merino we are able to characterize the basins of attractions of …

Fresh: Fair And Efficient Slot Configuration And Scheduling For Hadoop Clusters, Jiayin Wang, Yi Yao, Ying Mao, Bo Sheng, Ningfang Mi

Department of Computer Science Faculty Scholarship and Creative Works

Hadoop is an emerging framework for parallel big data processing. While becoming popular, Hadoop is too complex for regular users to fully understand all the system parameters and tune them appropriately. Especially when processing a batch of jobs, default Hadoop setting may cause inefficient resource utilization and unnecessarily prolong the execution time. This paper considers an extremely important setting of slot configuration which by default is fixed and static. We proposed an enhanced Hadoop system called FRESH which can derive the best slot setting, dynamically configure slots, and appropriately assign tasks to the available slots. The experimental results show that …

Evaluating The Progress Of A Mangrove Reforestation Project On Isla Galeta, Colon, Abigail Hope Outterson

Independent Study Project (ISP) Collection

Just off the Atlantic coast of Panama, a dynamic and self-renewing ecosystem takes advantage of the tropical climate and swampy conditions. Guarding Punta Galeta’s shores since before it was a U.S. navy base in the 1930’s, mangroves that have persisted here for centuries now draw scientists and tourists alike from all over the world to the Smithsonian Tropical Research Center. Once viewed as unproductive, distasteful environments, mangroves are increasingly recognized worldwide as critical habitat for endangered and commercially significant species, as well as for their ecological and aesthetic value. Uniquely adapted to survive in saline environments, mangroves combine methods of …

Big Data In Healthcare: What Is It Used For?, Rebecca Hermon, Patricia A H Williams

Australian eHealth Informatics and Security Conference

Big data analytics is a growth area with the potential to provide useful insight in healthcare. Whilst many dimensions of big data still present issues in its use and adoption, such as managing the volume, variety, velocity, veracity, and value, the accuracy, integrity, and semantic interpretation are of greater concern in clinical application. However, such challenges have not deterred the use and exploration of big data as an evidence source in healthcare. This drives the need to investigate healthcare information to control and reduce the burgeoning cost of healthcare, as well as to seek evidence to improve patient outcomes. Whilst …

Optical Characterization And Distribution Of Chromophoric Dissolved Organic Matter (Cdom) In Soil Porewater From A Salt Marsh Ecosystem, Catherine D. Clark, Paige Aiona, Jason K. Keller, Warren J. De Bruyn

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

To characterize chromophoric dissolved organic matter (CDOM) in marsh porewaters and its contribution as a carbon source, optical properties (absorbance, fluorescence indices, 3-dimensional excitation-emission matrices [EEMs]) of soil porewater and surface water were measured in a southern Californian salt marsh. Absorption coefficients and fluorescence intensities were higher in porewater than in overlying surface waters, consistent with higher CDOM concentration at depth. Humic-type peaks A and C were observed in EEMs in all samples, and peak M was observed in surface waters and shallow porewater to -5 cm depth. Fluorescence:absorbance (flu:abs) ratios and spectral slopes (S) decreased across the surface interface, …

Estimation Of Inbreeding And Substructure Levels In African-Derived Brazilian Quilombo Populations, Renan B. Lemes, Kelly Nunes, Diogo Meyer, Regina Célia Mingroni-Netto, Paulo A. Otto

Human Biology Open Access Pre-Prints

The present paper deals with the estimation of inbreeding and substructure levels in a set of ten (later regrouped as eight) African-derived quilombo communities from the Ribeira River Valley in the southern portion of the state of São Paulo, Brazil. Inbreeding levels were assessed through F values estimated from the direct analysis of genealogical data and from the statistical analysis of a large set of 30 molecular markers. The levels of population substructure found were modest, as well as the degree of inbreeding: in the set of all communities considered together, F values ranged from 0.00136 to 0.00248, when using …

Managing Wireless Security Risks In Medical Services, Brian Cusack, Akar Kyaw

Australian eHealth Informatics and Security Conference

Medical systems are designed for a range of end users from different professional skill groups and people who carry the devices in and on their bodies. Open, accurate, and efficient communication is the priority for medical systems and consequently strong protection costs are traded against the utility benefits for open systems. In this paper we assess the vulnerabilities created by the professional and end user expectations, and theorise ways to mitigate wireless security vulnerabilities. The benefits of wireless medical services are great in terms of efficiencies, mobility, and information management. These benefits may be realised by treating the vulnerabilities and …

Control Of Responses Of Smart Plate Structures Under Non-Stationary Random Excitations, Xiaojian Yang

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

This thesis is concerned with an investigation of the control of responses of plate structures with piezoelectric layers and under complicated excitations modeled as a non-stationary random process. The plate structures and piezoelectric layers are both discretized by the mixed formulation finite element method (FEM).

The investigation consists of three parts. The first part is a literature survey and theoretical development. The second part is the eigenvalue solution and computation of uncontrolled response statistics of laminated plate structures under nonstationary random excitations. The final part is the introduction and application of the stochastic central difference (SCD) method that was presented …

A Study Of Fe3O4 Magnetic Nanoparticle Rf Heating In Gellan Gum Polymer Under Various Experimental Conditions For Potential Application In Drug Delivery, Gabriel Marcus

USF Tampa Graduate Theses and Dissertations

Magnetic nanoparticles (MNPs) have found use in a wide variety of biomedical applications including hyperthermia, imaging and drug delivery. Certain physical properties, such as the ability to generate heat in response to an alternating magnetic field, make these structures ideal for such purposes. This study's objective was to elucidate the mechanisms primarily responsible for RF MNP heating and determine how such processes affect polymer solutions that might be useful in drug delivery. 15-20 nm magnetite (Fe₃O₄) nanoparticles at 0.2% and 0.5% concentrations were heated with RF fields of different strengths (200 Oe, 400 Oe and 600 …

Generalized Framework For Similarity Measure Of Time Series, Hongsheng Yin, Honggang Qi, Jingwen Xu, William N. N. Hung, Xiaoyu Song

Electrical and Computer Engineering Faculty Publications and Presentations

Currently, there is no definitive and uniform description for the similarity of time series, which results in difficulties for relevant research on this topic. In this paper, we propose a generalized framework to measure the similarity of time series. In this generalized framework, whether the time series is univariable or multivariable, and linear transformed or nonlinear transformed, the similarity of time series is uniformly defined using norms of vectors or matrices.The definitions of the similarity of time series in the original space and the transformed space are proved to be equivalent. Furthermore, we also extend the theory on similarity of …

Nucleation At The Contact Line Observed On Nanotextured Surfaces, C W. Gurganus, J. C. Charnawskas, A. B. Kostinski, R. A. Shaw

Department of Physics Publications

It has been conjectured that roughness plays a role in surface nucleation, the tendency for freezing to begin preferentially at the liquid-gas interface. Using high speed imaging, we sought evidence for freezing at the contact line on catalyst substrates with imposed characteristic length scales (texture). Length scales consistent with the critical nucleus size and with δ∼τ/σ, where τ is a relevant line tension and σ is the surface tension, range from nanometers to micrometers. It is found that nanoscale texture causes a shift in the nucleation of ice in supercooled water to the three-phase contact line, while microscale texture does …

Illusionism: Making The Problem Of Hallucinations Disappear, Rami El Ali

Open Access Dissertations

My dissertation contributes to a central and ongoing debate in the philosophy of perception concerning the fundamental nature of perceptual states. Such states include cases like seeing, hearing, or tasting, as well as cases of merely seeming to see, hear, or taste. A central question concerning these states arises in light of misperceptual phenomena. While a commonsensical picture of perceptual states construes them as simply relating us to the external and mind independent world’s objects, some misperceptual cases suggest that these states fall short of such world contact. The result is that perceptual states are either thought to fundamentally consist …

Polynomials With Prescribed Bad Primes, David P. Roberts

Mathematics Publications

We tabulate polynomials in ℚ[t] with a given factorization partition, bad reduction entirely within a given set of primes, and satisfying auxiliary conditions associated to 0, 1, and ∞. We explain how these polynomials are of particular interest because of their role in the construction of nonsolvable number fields of arbitrarily large degree and bounded ramification.
