Functional Car Models For Spatially Correlated Functional Datasets, Lin Zhang, Veerabhadran Baladandayuthapani, Hongxiao Zhu, Keith A. Baggerly, Tadeusz Majewski, Bogdan Czerniak, Jeffrey S. Morris Jan 2016

Functional Car Models For Spatially Correlated Functional Datasets, Lin Zhang, Veerabhadran Baladandayuthapani, Hongxiao Zhu, Keith A. Baggerly, Tadeusz Majewski, Bogdan Czerniak, Jeffrey S. Morris

Jeffrey S. Morris

We develop a functional conditional autoregressive (CAR) model for spatially correlated data for which functions are collected on areal units of a lattice. Our model performs functional response regression while accounting for spatial correlations with potentially nonseparable and nonstationary covariance structure, in both the space and functional domains. We show theoretically that our construction leads to a CAR model at each functional location, with spatial covariance parameters varying and borrowing strength across the functional domain. Using basis transformation strategies, the nonseparable spatial-functional model is computationally scalable to enormous functional datasets, generalizable to different basis functions, and can be used on ...


Isotopic Discrimination In The Double-Crested Cormorant (Phalacrocorax Auritus), Elizabeth C. Craig, Brian S. Dorr, Katie C. Hanson-Dorr, Jed P. Sparks, Paul D. Curtis Oct 2015

Isotopic Discrimination In The Double-Crested Cormorant (Phalacrocorax Auritus), Elizabeth C. Craig, Brian S. Dorr, Katie C. Hanson-Dorr, Jed P. Sparks, Paul D. Curtis

Brian S Dorr

The diet-tissue discrimination factor is the amount by which a consumer’s tissue varies isotopically from its diet, and is therefore a key element in models that use stable isotopes to estimate diet composition. In this study we measured discrimination factors in blood (whole blood, red blood cells and plasma), liver, muscle and feathers of Double- crested Cormorants (Phalacrocorax auritus) for stable isotope ratios of carbon, nitrogen and sulfur. Cormorants exhibited discrimination factors that differed significantly among tissue types (for carbon and nitrogen), and differed substantially (in the context of the isotopic variation among relevant prey species) from those observed ...

Comparative Analysis Of Biodegradability Of Biodiesel Obtained By Conventional And Non-Conventional Methods, Innovative Research Publications Irp India, Nagaraja Y. P, Chandrashekhar Biradar Mar 2015

Comparative Analysis Of Biodegradability Of Biodiesel Obtained By Conventional And Non-Conventional Methods, Innovative Research Publications Irp India, Nagaraja Y. P, Chandrashekhar Biradar

Innovative Research Publications IRP India

Biodiesel is an alternative to conventional diesel fuel made from renewable resources. No engine modifications are required to use biodiesel in place of crude oil-based diesel. The use of biodiesel resulted in lower emissions of unburned hydrocarbons, carbon monoxide and particulate matter. Biodiesel also increased catalytic converter efficiency in reducing particulate emissions. Chemical characterization also revealed lower levels of some toxic and reactive hydrocarbon species when biodiesel fuels were used. In the present work, biodiesel is produced by both conventional and non-conventional methods to determine the biodegradability effect using microorganisms obtained from soil collected from the vicinity of a petrol ...

Social Science Contributions Compared In Synthetic Biology And Nanotechnology, Philip Shapira, Jan Youtie, Yin Li Feb 2015

Social Science Contributions Compared In Synthetic Biology And Nanotechnology, Philip Shapira, Jan Youtie, Yin Li

Philip Shapira

With growing attention to societal issues and implications of synthetic biology, we investigate sources of social science publication knowledge in synthetic biology and probe what might be learned by comparison with earlier rounds of social science research in nanotechnology. “Social science” research is broadly defined to include publications in conventional social science as well as humanities, law, ethics, business, and policy fields. We examine the knowledge clusters underpinning social science publications in nanotechnology and synthetic biology using a methodology based on the analysis of cited references. Our analysis finds that social science research in synthetic biology already has traction and ...


Annual Variation In Autumn Migration Phenology And Energetic Condition At A Stopover Site In The Western United States, Robert A. Miller, Jay D. Carlisle, Neil Paprocki, Gregory S. Kaltenecker, Julie A. Heath Jan 2015

Annual Variation In Autumn Migration Phenology And Energetic Condition At A Stopover Site In The Western United States, Robert A. Miller, Jay D. Carlisle, Neil Paprocki, Gregory S. Kaltenecker, Julie A. Heath

Robert Miller

Climate change is having a dramatic effect on many migratory species. Changes in climate may lead to changes in food availability or other proximate cues that affect migratory behavior. We used 13 years (2000–2012) of data on songbird banding and raptor migration counts and captures during autumn migration in the intermountain West to evaluate whether regional temperature or precipitation or hemispheric climate indices predicted autumn migratory timing and energetic condition. We examined overall trends and evaluated the effects of diet and migratory distance on phenology and conditional responses. For the 13-year study period, no temperature, precipitation, or climate index ...


Importance Of Genetic Diversity Assessment In Crop Plants And Its Recent Advances: An Overview Of Its Analytical Perspectives, Mahalingam Govindaraj Jan 2015

Importance Of Genetic Diversity Assessment In Crop Plants And Its Recent Advances: An Overview Of Its Analytical Perspectives, Mahalingam Govindaraj

Mahalingam Govindaraj

The importance of plant genetic diversity (PGD) is now being recognized as a specific area since exploding population with urbanization and decreasing cultivable lands are the critical factors contributing to food insecurity in developing world.Agricultural scientists realized that PGD can be captured and stored in the formof plant genetic resources (PGR) such as gene bank,DNA library, and so forth, in the biorepository which preserve genetic material for long period. However, conserved PGR must be utilized for crop improvement in order to meet future global challenges in relation to food and nutritional security.This paper comprehensively reviews four important ...

Cloning And Expression Analysis Of Drosophila Extracellular Cu Zn Superoxide Dismutase, Michael J. Blackney, Rebecca Cox, David Shepherd, Joel D. Parker Dec 2014

Cloning And Expression Analysis Of Drosophila Extracellular Cu Zn Superoxide Dismutase, Michael J. Blackney, Rebecca Cox, David Shepherd, Joel D. Parker

Joel D Parker

In the present study, we cloned and sequenced the mRNAs of the Sod3 [extracellular Cu Zn SOD (superoxide dismutase)] gene in Drosophila and identified two mRNA products formed by alternative splicing. These products code for a long and short protein derived from the four transcripts found in global expression studies (Flybase numbers Dmel\CG9027, FBgn0033631). Both mRNA process variants contain an extracellular signalling sequence, a region of high homology to the Sod1 (cytoplasmic Cu Zn SOD) including a conserved AUG start, with the longer form also containing a hydrophobic tail. The two fully processed transcripts are homologous to Caenorhabditis elegans ...

Mathematical Structure Of Fuzzy Modeling Of Medical Diagnoses By Using Clustering Models, R.W. W. Hndoosh Aug 2014

Mathematical Structure Of Fuzzy Modeling Of Medical Diagnoses By Using Clustering Models, R.W. W. Hndoosh

R. W. Hndoosh

An Adaptive-Network-based Fuzzy Inference System ANFIS with different techniques of clustering is successfully developed to solve one of the problems of medical diagnoses, because it has the advantage of powerful modeling ability. In this paper, we propose the generation of an adaptive neuro-Fuzzy Inference System model using different clustering models such as a subtractive fuzzy clustering (SFC) model and a fuzzy c-mean clustering (FCM) model in the Takagi-Sugeno (TS) fuzzy model for selecting the hidden node centers. An experimental result on datasets of medical diagnoses shows the proposed model with two models of clustering (ANFIS-SFC & ANFIS-FCM) while comparing the same ...

Real-Time Pcr And Real-Time Rt-Pcr Applications In Food Labelling And Gene Expression Studies, Arash Kashani, Tasmanian Institute Of Agriculture Apr 2014

Real-Time Pcr And Real-Time Rt-Pcr Applications In Food Labelling And Gene Expression Studies, Arash Kashani, Tasmanian Institute Of Agriculture

Emily Scott

Polymerase chain reaction (PCR) as a scientific invention, has revolutionized molecular biology and led to real-time PCR and later, real-time reverse transcription PCR (Real-Time RT-PCR). These two techniques enable scientists to conduct PCR detection of amplified gene products and expression analysis of targeted genes. Quantitative polymerase chain reaction (qPCR), also called real-time polymerase chain reaction, is a recent modification to PCR that utilizes fluorescent reporter molecular techniques to monitor the production of amplified products during each cycle of the PCR reaction, and enables both detection and quantification of specific sequences in complex mixtures. Over the past decade, real-time PCR applications ...

Mechanisms Of Photoperiod In Regulation Of Rice Flowering, Abdulrahman Mahmoud Dogara, Salisu Muhammad Tahir, Idris Shehu, Mustapha Abbah

Emily Scott

A study on the photoperiodic control of flower in rice is advancing and rice has become an example of short day plant. Many genes used in flowering time determination in rice have been identified by many methods. The conclusion from these molecular studies is a remarkable conservation of genes which play an important role in the control of flowering time in rice. The rice photoperiod sensitivity gene Hd3a was originally detected as a heading date related quantitative trait locus found on chromosome 6 of rice. High resolution linkage mapping of Hd3a was carried using a huge segregating population derived from ...

Lichens Of Six Vernal Pools In Acadia National Park, Maine, Usa, Jason Barton, Brett Ciccotelli, Jillian E. Gall, Fred C. Olday, Bruce Connery, Tanner B. Harris, Alan M. Fryday, Nishanta Rajakaruna

Nishanta Rajakaruna

Whereas lichen-habitat relations have been well-documented globally, literature on lichens of vernal pools is scant. We surveyed six vernal pools at Acadia National Park on Mount Desert Island, Maine, USA for their lichen diversity. Sixty-seven species were identified, including seven species that are new reports for Acadia National Park: Fuscidea arboricola, Hypogymnia incurvoides, Lepraria finkii, Phaeographis inusta, Ropalospora viridis, Usnea flammea, and Violella fucata. Five species are considered uncommon or only locally common in New England: Everniastrum catawbiense, Hypogymnia krogiae, Pseudevernia cladonia, Usnea flammea, and Usnea merrillii. This work represents the first survey of lichens from vernal pools in Acadia ...


Effects Of Prey Abundance On Breeding Season Diet Of Northern Goshawks (Accipiter Gentilis) Within An Unusual Prey Landscape, Robert A. Miller, Jay D. Carlisle, Marc J. Bechard Mar 2014

Effects Of Prey Abundance On Breeding Season Diet Of Northern Goshawks (Accipiter Gentilis) Within An Unusual Prey Landscape, Robert A. Miller, Jay D. Carlisle, Marc J. Bechard

Robert Miller

A critical element of diet analysis is species adaptability to alternative prey sources. The breeding season diet of Northern Goshawks (Accipiter gentilis) includes both mammalian and avian species, varies geographically, and is often dependent upon tree squirrels of the genera Sciurus and Tamiasciurus>/i>. We studied alternative prey sources of Northern Goshawks in the South Hills of south-central Idaho, an area where tree squirrels are naturally absent and other prey frequently important in the diet of goshawks, such as smaller corvids, are uncommon. We quantified the diet of goshawks using nest cameras and surveyed abundance of prey using line transects ...

Serpentine Soils, Nishanta Rajakaruna, R. S. Boyd Jan 2014

Serpentine Soils, Nishanta Rajakaruna, R. S. Boyd

Nishanta Rajakaruna

Serpentine soils are weathered products of a range of ultramafic rocks composed of ferromagnesian silicates. Serpentine more accurately refers to a group of minerals, including antigorite, chrysotile, and lizardite, in hydrothermally altered ultramafic rocks. Common ultramafic rock types include peridotites (dunite, wehrlite, harzburgite, lherzolite) and the secondary alteration products formed by their hydration within the Earth’s crust, including serpentinite, the primary source of serpentine soil. Serpentine soils are generally deficient in plant essential nutrients such as nitrogen, phosphorus, potassium, and sulfur; have a calcium-to-magnesium (Ca:Mg) molar ratio of less than 1; and have elevated levels of heavy metals ...


Bayesian Joint Selection Of Genes And Pathways: Applications In Multiple Myeloma Genomics, Lin Zhang, Jeffrey S. Morris, Jiexin Zhang, Robert Orlowski, Veerabhadran Baladandayuthapani Jan 2014

Bayesian Joint Selection Of Genes And Pathways: Applications In Multiple Myeloma Genomics, Lin Zhang, Jeffrey S. Morris, Jiexin Zhang, Robert Orlowski, Veerabhadran Baladandayuthapani

Jeffrey S. Morris

It is well-established that the development of a disease, especially cancer, is a complex process that results from the joint effects of multiple genes involved in various molecular signaling pathways. In this article, we propose methods to discover genes and molecular pathways significantly associ- ated with clinical outcomes in cancer samples. We exploit the natural hierarchal structure of genes related to a given pathway as a group of interacting genes to conduct selection of both pathways and genes. We posit the problem in a hierarchical structured variable selection (HSVS) framework to analyze the corresponding gene expression data. HSVS methods conduct ...

Comparative Genomics Of Closely Related Salmonella Enterica Serovar Typhi Strains Reveals Genome Dynamics And The Acquisition Of Novel Pathogenic Elements, Kien-Pong Yap Jan 2014

Comparative Genomics Of Closely Related Salmonella Enterica Serovar Typhi Strains Reveals Genome Dynamics And The Acquisition Of Novel Pathogenic Elements, Kien-Pong Yap

Kien-Pong Yap

Background Typhoid fever is an infectious disease of global importance that is caused by Salmonella enterica subsp. enterica serovar Typhi (S. Typhi). This disease causes an estimated 200,000 deaths per year and remains a serious global health threat. S. Typhi is strictly a human pathogen, and some recovered individuals become long-term carriers who continue to shed the bacteria in their faeces, thus becoming main reservoirs of infection.

Results A comparative genomics analysis combined with a phylogenomic analysis revealed that the strains from the outbreak and carrier were closely related with microvariations and possibly derived from a common ancestor. Additionally ...


Seedling Growth Rates And Light Requirements Of Subtropical Rainforest Trees Associated With Basaltic And Rhyolitic Soils, C H. Lusk, Kerrie M. Sendall, P J. Clarke Jan 2014

Seedling Growth Rates And Light Requirements Of Subtropical Rainforest Trees Associated With Basaltic And Rhyolitic Soils, C H. Lusk, Kerrie M. Sendall, P J. Clarke

Kerrie M Sendall

A trade-off between shade tolerance and growth in open conditions is widely believed to underlie the dynamics of humid forests. Little is known about how the growth versus shade tolerance trade-off interacts with other major trade-offs associated with differential adaptation to major environmental factors besides light. We asked whether the growth versus shade tolerance trade-off differed between subtropical rainforest tree assemblages native to basaltic (fertile) and rhyolitic (infertile) soils in northern New South Wales, because of the allocational costs of adaptation to low nutrient availability. Seedling relative growth rates of six basalt specialists and five rhyolite specialists were measured in ...

Differential Habitat Use By Common Watersnakes (Nerodia Sipedon), Lorin A. Neuman-Lee, Andrew M. Durso, Nicholas M. Kiriazis, Melanie J. Olds, Stephen J. Mullin Dec 2013

Differential Habitat Use By Common Watersnakes (Nerodia Sipedon), Lorin A. Neuman-Lee, Andrew M. Durso, Nicholas M. Kiriazis, Melanie J. Olds, Stephen J. Mullin

Stephen J. Mullin

Understanding intraspecific variation in habitat use is important for the management of any species. In many studies of reptiles, habitat use by juveniles is poorly understood when compared to their adult conspecifics because of capture biases and logistical constraints. We compared habitat use between sexes and age classes of Common Watersnakes (Nerodia sipedon) at a reservoir in central Illinois. Juvenile N. sipedon occurred more frequently in habitat with high canopy cover, whereas adult N. sipedon, especially reproductive females, were found exclusively in habitat with no canopy cover. Adult males used both locations equally. We emphasize the need to investigate ontogenetic ...
