Mechanisms And Ecological Role Of Carbon Transfer Within Coastal Seascapes, Glenn A. Hyndes, Ivan Nagelkerken, Rebecca Mcleod, Rod Connolly, Paul S. Lavery, Mathew A. Vanderklift Jan 2014

Mechanisms And Ecological Role Of Carbon Transfer Within Coastal Seascapes, Glenn A. Hyndes, Ivan Nagelkerken, Rebecca Mcleod, Rod Connolly, Paul S. Lavery, Mathew A. Vanderklift

Research outputs 2013

Worldwide, coastal systems provide some of the most productive habitats, which potentially influence a range of marine and terrestrial ecosystems through the transfer of nutrients and energy. Several reviews have examined aspects of connectivity within coastal seascapes, but the scope of those reviews has been limited to single systems or single vectors. We use the transfer of carbon to examine the processes of connectivity through multiple vectors in multiple ecosystems using four coastal seascapes as case studies. We discuss and compare the main vectors of carbon connecting different ecosystems, and then the natural and human-induced factors that influence the magnitude …

Seagrass Canopy Photosynthetic Response Is A Function Of Canopy Density And Light Environment: A Model For Amphibolis Griffithii, John D. Hedley, Kathryn Mcmahon, Peter Fearns Jan 2014

Seagrass Canopy Photosynthetic Response Is A Function Of Canopy Density And Light Environment: A Model For Amphibolis Griffithii, John D. Hedley, Kathryn Mcmahon, Peter Fearns

Research outputs 2014 to 2021

A three-dimensional computer model of canopies of the seagrass Amphibolis griffithii was used to investigate the consequences of variations in canopy structure and benthic light environment on leaf-level photosynthetic saturation state. The model was constructed using empirical data of plant morphometrics from a previously conducted shading experiment and validated well to in-situ data on light attenuation in canopies of different densities. Using published values of the leaf-level saturating irradiance for photosynthesis, results show that the interaction of canopy density and canopy-scale photosynthetic response is complex and non-linear, due to the combination of self-shading and the non-linearity of photosynthesis versus irradiance …

Psychophysiological Research Of Borderline Personality Disorder: Review And Implications For Biosocial Theory, Tara Cavazzi, Rodrigo Becerra Jan 2014

Psychophysiological Research Of Borderline Personality Disorder: Review And Implications For Biosocial Theory, Tara Cavazzi, Rodrigo Becerra

Research outputs 2014 to 2021

According to the Biosocial theory, Borderline Personality Disorder (BPD) is developed by a biological predisposition to hyperarousal and hyperreactivity combined with an invalidating environment. Although widely supported by subjective measures, the impaired insight present in BPD may skew results, and thus psychophysiological measures have been suggested as an alternative method of examining possible biological differences in BPD. The current review aimed to critically assess psychophysiological research of BPD by electronic searching of relevant databases, with 22 articles meeting inclusion criteria. Results showed that in contrast to the hyperarousal proposed in the Biosocial theory, BPD was associated with hypoarousal and hyporeactivity …

Biomarkers Of Alzheimer's Disease Risk In Peripheral Tissues; Focus On Buccal Cells, Maxime François, Wayne Leifert, Ralph Martins, Philip Thomas, Michael Fenech Jan 2014

Biomarkers Of Alzheimer's Disease Risk In Peripheral Tissues; Focus On Buccal Cells, Maxime François, Wayne Leifert, Ralph Martins, Philip Thomas, Michael Fenech

Research outputs 2014 to 2021

Alzheimer's disease (AD) is a progressive degenerative disorder of the brain and is the most common form of dementia. To-date no simple, inexpensive and minimally invasive procedure is available to confirm with certainty the early diagnosis of AD prior to the manifestations of symptoms characteristic of the disease. Therefore, if population screening of individuals is to be performed, more suitable, easily accessible tissues would need to be used for a diagnostic test that would identify those who exhibit cellular pathology indicative of mild cognitive impairment (MCI) and AD risk so that they can be prioritized for primary prevention. This need …

Leaf Gas Films Delay Salt Entry And Enhance Underwater Photosynthesis And Internal Aeration Of Melilotus Siculus Submerged In Saline Water, Natasha Lea Teakle, Timothy David Colmer, Ole Pedersen Jan 2014

Leaf Gas Films Delay Salt Entry And Enhance Underwater Photosynthesis And Internal Aeration Of Melilotus Siculus Submerged In Saline Water, Natasha Lea Teakle, Timothy David Colmer, Ole Pedersen

Research outputs 2014 to 2021

A combination of flooding and salinity is detrimental to most plants. We studied tolerance of complete submergence in saline water for Melilotus siculus, an annual legume with superhydrophobic leaf surfaces that retain gas films when under water. M.siculus survived complete submergence of 1 week at low salinity (up to 50molm-3 NaCl), but did not recover following de-submergence from 100molm-3 NaCl. The leaf gas films protected against direct salt ingress into the leaves when submerged in saline water, enabling underwater photosynthesis even after 3d of complete submergence. By contrast, leaves with the gas films experimentally removed suffered from substantial Na+ and …

Integrating Soil And Plant Tissue Tests And Using An Artificial Intelligence Method For Data Modelling Is Likely To Improve Decisions For In-Season Nitrogen Management, Andreas Neuhaus, Leisa Armstrong, Jinsong Leng, Dean Diepeveen, Geoff Anderson Jan 2014

Integrating Soil And Plant Tissue Tests And Using An Artificial Intelligence Method For Data Modelling Is Likely To Improve Decisions For In-Season Nitrogen Management, Andreas Neuhaus, Leisa Armstrong, Jinsong Leng, Dean Diepeveen, Geoff Anderson

Research outputs 2014 to 2021

This paper hypothesizes that there is value in combining soil, climate and plant tissue data to give more reliable advice on nitrogen top-ups in-season when compared with models that are currently available. The benefit of soil and climate data is to factor in N mineralisation and potential yield while plant test data is a more direct approach of yield estimates when considering firstly plant N uptake from the whole soil profile and secondly biomass (important yield component). Plant test data are closer to yield in time and space than soil test data, shortening the time period for any yield prognosis …

Are We Approaching Pit Lake Closure From The Wrong Perspective?, Mark A. Lund, Melanie L. Blanchette Jan 2014

Are We Approaching Pit Lake Closure From The Wrong Perspective?, Mark A. Lund, Melanie L. Blanchette

Research outputs 2014 to 2021

Pit lakes are similar to natural lakes formed by faulting, glacial action, volcanic action and asteroid collisions. These natural lakes have, after thousands of years, developed into environmentally significant ecosystems. As artificial constructs, pit lakes can be modified prior to filling to enhance lake attributes, such as modification of catchment size, creation of littoral zones and addition of organic matter. Significant advances could be made in successful closure and relinquishment of pit lakes, by 1) choosing appropriate model lakes, 2) understanding successional processes, 3) designing pit lakes to enhance ecological values, and 4) recognizing that it will take time to …

High Fibre Diets And Alzheimer's Disease, Ian J. Martins, Warnakulasuriya M. Fernando Jan 2014

High Fibre Diets And Alzheimer's Disease, Ian J. Martins, Warnakulasuriya M. Fernando

Research outputs 2014 to 2021

The convergence of diet and AD may be related to the effects of phytosterols since plasma cholesterol is closely linked and regulated by phytosterols. Dietary fibre modifications that are low in fat and glucose reduce the risk for AD by not only effecting cell membranes and nutrient sensing G coupled receptors but also by regulating number of nuclear receptors such as histone deacetylases (HDAC) and peroxisome proliferator activated receptors (PPAR) that control glucose, fatty acids and cholesterol and have significant effects on the brain cholesterol homeostasis and amyloidosis. The peripheral sink Aβ hypothesis indicates that the peripheral clearance of Aβ …

Pax Genes: Regulators Of Lineage Specification And Progenitor Cell Maintenance, Judith A. Blake, Mel R. Ziman Jan 2014

Pax Genes: Regulators Of Lineage Specification And Progenitor Cell Maintenance, Judith A. Blake, Mel R. Ziman

Research outputs 2014 to 2021

Pax genes encode a family of transcription factors that orchestrate complex processes of lineage determination in the developing embryo. Their key role is to specify and maintain progenitor cells through use of complex molecular mechanisms such as alternate RNA splice forms and gene activation or inhibition in conjunction with protein co-factors. The significance of Pax genes in development is highlighted by abnormalities that arise from the expression of mutant Pax genes. Here, we review the molecular functions of Pax genes during development and detail the regulatory mechanisms by which they specify and maintain progenitor cells across various tissue lineages. We …

Factors Influencing Pacing In Triathlon, Sam Shi Xuan Wu, Jeremiah P. Peiffer, Jeanick Brisswalter, Kazunori Nosaka, Chris Abbiss Jan 2014

Factors Influencing Pacing In Triathlon, Sam Shi Xuan Wu, Jeremiah P. Peiffer, Jeanick Brisswalter, Kazunori Nosaka, Chris Abbiss

Research outputs 2014 to 2021

Triathlon is a multisport event consisting of sequential swim, cycle, and run disciplines performed over a variety of distances. This complex and unique sport requires athletes to appropriately distribute their speed or energy expenditure (ie, pacing) within each discipline as well as over the entire event. As with most physical activity, the regulation of pacing in triathlon may be influenced by a multitude of intrinsic and extrinsic factors. The majority of current research focuses mainly on the Olympic distance, whilst much less literature is available on other triathlon distances such as the sprint, half-Ironman, and Ironman distances. Furthermore, little is …

Template-Based C8-Scorpion: A Protein 8 State Secondary Structure Prediction Method Using Structural Information And Context-Based Features, Ashraf Yaseen, Yaohang Li Jan 2014

Template-Based C8-Scorpion: A Protein 8 State Secondary Structure Prediction Method Using Structural Information And Context-Based Features, Ashraf Yaseen, Yaohang Li

Computer Science Faculty Publications

Background: Secondary structures prediction of proteins is important to many protein structure modeling applications. Correct prediction of secondary structures can significantly reduce the degrees of freedom in protein tertiary structure modeling and therefore reduces the difficulty of obtaining high resolution 3D models.

Methods: In this work, we investigate a template-based approach to enhance 8-state secondary structure prediction accuracy. We construct structural templates from known protein structures with certain sequence similarity. The structural templates are then incorporated as features with sequence and evolutionary information to train two-stage neural networks. In case of structural templates absence, heuristic structural information is incorporated instead. …

Automated Identification Of Cell Type Specific Genes In The Mouse Brain By Image Computing Of Expression Patterns, Rongjian Li, Wenlu Zhang, Shuiwang Ji Jan 2014

Automated Identification Of Cell Type Specific Genes In The Mouse Brain By Image Computing Of Expression Patterns, Rongjian Li, Wenlu Zhang, Shuiwang Ji

Computer Science Faculty Publications

Background: Differential gene expression patterns in cells of the mammalian brain result in the morphological, connectional, and functional diversity of cells. A wide variety of studies have shown that certain genes are expressed only in specific cell-types. Analysis of cell-type-specific gene expression patterns can provide insights into the relationship between genes, connectivity, brain regions, and cell-types. However, automated methods for identifying cell-type-specific genes are lacking to date.

Results: Here, we describe a set of computational methods for identifying cell-type-specific genes in the mouse brain by automated image computing of in situ hybridization (ISH) expression patterns. We applied invariant image feature …

Tracing Beta Strands Using Strandtwister From Cryo-Em Density Maps At Medium Resolutions, Dong Si, Jing He Jan 2014

Tracing Beta Strands Using Strandtwister From Cryo-Em Density Maps At Medium Resolutions, Dong Si, Jing He

Computer Science Faculty Publications

Major secondary structure elements such as α helices and β sheets can be computationally detected from cryoelectron microscopy (cryo-EM) density maps with medium resolutions of 5–10 A˚ . However, a critical piece of information for modeling atomic structures is missing, because there are no tools to detect β strands from cryo-EM maps at medium resolutions. We propose a method, StrandTwister, to detect the traces of β strands through the analysis of twist, an intrinsic nature of a β sheet. StrandTwister has been tested using 100 β sheets simulated at 10 A˚ resolution and 39 β sheets computationally detected from cryo-EM …

Theoretical And Experimental Investigations To Improve The Performance Of Surface Acoustic Wave (Saw) Biosensors, Mandek Richardson Jan 2014

Theoretical And Experimental Investigations To Improve The Performance Of Surface Acoustic Wave (Saw) Biosensors, Mandek Richardson

USF Tampa Graduate Theses and Dissertations

The objective of this dissertation is to improve the performance of surface acoustic wave (SAW) biosensors for use in point-of-care-testing (POCT) applications. SAW biosensors have the ability to perform fast, accurate detection of an analyte in real time without the use of labels. However, the technology suffers from the inability to differentiate between specific and non-specific binding. Due to this limitation, direct testing of bodily fluids using SAW sensors to accurately determine an analyte's concentration is difficult. In addition, these sensors are challenged by the need to detect small concentrations of a biomarker that are typically required to give a …

(Dis)Abled Gaming: An Autoethnographic Analysis Of Decreasing Accessibility For Disabled Gamers, Kyle David Romano Jan 2014

(Dis)Abled Gaming: An Autoethnographic Analysis Of Decreasing Accessibility For Disabled Gamers, Kyle David Romano

USF Tampa Graduate Theses and Dissertations

Within the context of culture, disability has long existed as a stigmatizing quality (Goffman, 1963). As a result, people with disabilities are often overlooked or completely omitted from various, cultural artifacts. This exclusion of people with disabilities is largely recognized as unproblematic because their disabilities imply an inevitable failing. Through my own experiences as a disabled gamer, I have recognized that video games have also framed gamers with disabilities as problematic. Video games are largely constructed in a one-size-fits-all mentality (Grammenos, 2014), where very specific people, with very specific kinds of bodies, are granted access to play them. Since disabled …
