Fire, Fuels, And Streams: The Effects And Effectiveness Of Riparian Treatments, Josh Mcdaniel

Joint Fire Science Program Digests

Fire is an important disturbance in riparian systems—consuming vegetation; increasing light; creating snags and debris flows; altering habitat structure; and affecting stream conditions, erosion, and hydrology. For many years, land managers have worked to keep fire out of riparian systems through the use of buffers. A number of projects funded by the Joint Fire Science Program are shedding light on the dynamics of fire in riparian systems. Recent research and field practice have shown that (1) riparian treatments can be beneficial and are not as risky as previously thought; and (2) riparian treatments need the “Goldilocks” prescribed fire—not too hot …

Iarc Monographs: 40 Years Of Evaluating Carcinogenic Hazards To Humans, Neil Pearce, Aaron Blair, Paolo Vineis, Wolfgang Ahrens, Aage Andersen, Melissa J. Perry, +Several Additional Authors

Environmental and Occupational Health Faculty Publications

Background: Recently, the International Agency for Research on Cancer (IARC) Programme for the Evaluation of Carcinogenic Risks to Humans has been criticized for several of its evaluations, and also for the approach used to perform these evaluations. Some critics have claimed that failures of IARC Working Groups to recognize study weaknesses and biases of Working Group members have led to inappropriate classification of a number of agents as carcinogenic to humans.

Objectives: The authors of this Commentary are scientists from various disciplines relevant to the identification and hazard evaluation of human carcinogens. We examined criticisms of the IARC classification process …

Imaging The Dipole-Dipole Energy Exchange Between Ultracold Rubidium Rydberg Atoms, Donald P. Fahey, Thomas J. Carroll, Michael W. Noel

Physics and Astronomy Faculty Publications

The long-range, anisotropic nature of the interaction among atoms in an ultracold dipolar gas leads to a rich array of possibilities for studying many-body physics. In this work, an ultracold gas of highly excited atoms is used to study energy transport due to the long-range dipole-dipole interaction. A technique is developed to measure both the internal energy states of the interacting Rydberg atoms and their positions in space. This technique is demonstrated by observing energy exchange between two spatially separated groups of Rydberg atoms excited to two different internal states. Simulations confirm the general features of the energy transport in …

Population Structure Of Mitochondrial Genomes In Saccharomyces Cerevisiae, John F. Wolters, Kenneth Chiu, Heather L. Fiumera

Biological Sciences Faculty Scholarship

Background: Rigorous study of mitochondrial functions and cell biology in the budding yeast, Saccharomyces cerevisiae has advanced our understanding of mitochondrial genetics. This yeast is now a powerful model for population genetics, owing to large genetic diversity and highly structured populations among wild isolates. Comparative mitochondrial genomic analyses between yeast species have revealed broad evolutionary changes in genome organization and architecture. A fine-scale view of recent evolutionary changes within S. cerevisiae has not been possible due to low numbers of complete mitochondrial sequences.

Results: To address challenges of sequencing AT-rich and repetitive mitochondrial DNAs (mtDNAs), we sequenced two divergent S. …

Mathematical Model: Comparative Study Of Thermal Effects Of Laser In Corneal Refractive Surgeries, Gokul Kc, Dil B. Gurung, Pushpa R. Adhikary

Applications and Applied Mathematics: An International Journal (AAM)

Lasers have been widely used in ophthalmology. Refractive errors are some of the most common ophthalmic abnormalities worldwide. Laser refractive surgery was developed to correct refractive errors myopia, hyperopia and astigmatism. Two types of laser surgical techniques: lamellar and thermal are available to reshape the corneal curvature. Ultraviolet (UV) emitting argon fluoride (ArF) excimer laser is used to sculpt cornea in lamellar procedures, whereas, infrared (IR) emitting holmium yttrium aluminum garnet (Ho: YAG) laser is used to shrink cornea in thermal procedure. Tissue heating is common in all types of laser surgical techniques. Hence, in this paper, a finite element …

Development Of New Synthetic Methods, Mechanistic Elucidation Of Novel Organic Reactions Using Quantum Calculations, And Harnessing The Power Of Continuous Flow Technologies, Trevor A. Hamlin

Doctoral Dissertations

The development of synthetic methodologies can be aided and improved upon by a critical understanding of the mechanistic pathways at play during a chemical reaction. Computational modeling has proven very valuable in this endeavor. My graduate research has focused on three areas in particular: (1) development of synthetic methodologies, (2) quantum chemical modeling, and (3) utilization of emerging technologies. These topics are highly relevant in the literature today and serve as a foundation to aid researchers in generations to come.

Mir-21-Mediated Decreased Neutrophil Apoptosis Is A Determinant Of Impaired Coronary Collateral Growth In Metabolic Syndrome, Rebecca Hutcheson, Russell Terry, Brenda Hutcheson, Rashmi Jadhav, Jennifer Chaplin, Erika Smith, Robert Barrington, Spencer D. Proctor, Petra Rocic

NYMC Faculty Publications

Coronary collateral growth (CCG) is impaired in metabolic syndrome. microRNA-21 (miR-21) is a proproliferative and antiapoptotic miR, which we showed to be elevated in metabolic syndrome. Here we investigate whether impaired CCG in metabolic syndrome involved miR-21-mediated aberrant apoptosis. Normal Sprague-Dawley (SD) and metabolic syndrome [J. C. Russel (JCR)] rats underwent transient, repetitive coronary artery occlusion [repetitive ischemia (RI)]. Antiapoptotic Bcl-2, phospho-Bad, and Bcl-2/Bax dimers were increased on days 6 and 9 RI, and proapoptotic Bax and Bax/Bax dimers and cytochrome-c release concurrently decreased in JCR versus SD rats. Active caspases were decreased in JCR versus SD rats (~50%). Neutrophils …

Student Autonomy Improves Learning: A Theoretical Justification Of The Empirical Results, Octavio Lerma, Vladik Kreinovich

Departmental Technical Reports (CS)

In many pedagogical situations, it is advantageous to give students some autonomy: for example, instead of assigning the same homework problem to all the students, to give students a choice between several similar problems, so that each student can choose a problem whose context best fits his or her experiences. A recent experimental study shows that there is a 45% correlation between degree of autonomy and student success. In this paper, we provide a theoretical explanation for this correlation value.

Why Deep Neural Networks: A Possible Theoretical Explanation, Chitta Baral, Olac Fuentes, Vladik Kreinovich

Departmental Technical Reports (CS)

In the past, the most widely used neural networks were 3-layer ones. These networks were preferred, since one of the main advantages of the biological neural networks -- which motivated the use of neural networks in computing -- is their parallelism, and 3-layer networks provide the largest degree of parallelism. Recently, however, it was empirically shown that, in spite of this argument, multi-layer ("deep") neural networks leads to a much more efficient machine learning. In this paper, we provide a possible theoretical explanation for the somewhat surprising empirical success of deep networks.

Moses And Liminality, David J. Krouwer

Electronic Theses and Dissertations

Marked by two significant water crossings, the Hebrew Bible establishes the wilderness period in the Pentateuch as a liminal period marking rites of passage for the Israelites. Using a narrative critical approach and an anthropological understanding of liminality, this paper shows that Moses was depicted with an abundance of liminal characteristics and these made him the ultimate transitional tool for God to use in the maturation rites of his people. Further, known Essene beliefs and the Dead Sea Scrolls, the texts of the religious community that inhabited the site of Qumran in the latter half of the second temple period, …

Investigating The Paleoecological Consequences Of Supercontinent Breakup: Sponges Clean Up In The Early Jurassic, Frank Corsetti, Kathleen Ritterbush, David Bottjer, Sarah Greene, Yadira Ibarra, Joyce Yager, A. Joshua West, William Berelson, Silvia Rosas, Thorsten Becker, Naomi Levine, Sean Loyd, Rowan Martindale, Victoria Petryshyn, Nathan Carroll, Elizabeth Petsios, Olivia Piazza, Carlie Pietsch, Jessica Stellmann, Jeffrey Thompson, Kirstin Washington, Dylan Wilmeth

Faculty Publications

The continued release of fossil fuel carbon into the atmosphere today means it is imperative to understand Earth system response to CO2 rise, and the geologic record offers unique opportunities to investigate such behavior. Stomatal and paleosol proxies demonstrate a large change in atmospheric pCO2 across the Triassic-Jurassic (T-J) transition, concomitant with the eruption and emplacement of the Central Atlantic Magmatic Province (CAMP) and the splitting of Pangea. As one of the “big 5” mass extinctions—when the so-called modern fauna was particularly hard hit—we know the biosphere was severely affected during this time, but the details are relatively poorly understood, …

Simangus Crossbreeding Proposal, Kaity Arburua

Agricultural Education and Communication

The purpose of this project is to develop a proposal for a crossbreeding plan specifically oriented towards a Central Valley beef producer interested in SimAngus cattle. In this project you will find information pertaining to the Simmental, Angus and SimAngus breeds, as well as industry goals and possible outcomes. This was designed in order to create tangible evidence and information, such a pamphlet/brochure, for the producer to evaluate; in hopes that the beef producer will implement this crossbreeding plan.

Questionable Validity Of The Catheter-Associated Urinary Tract Infection Metric Used For Value-Based Purchasing, Lindsay E. Calderon, Kevin T. Kavanagh, Mara K. Rice

Biological Sciences Faculty and Staff Research

Catheter-associated urinary tract infections (CAUTIs) occur in 290,000 US hospital patients annually, with an estimated cost of $290 million. Two different measurement systems are being used to track the US health care system's performance in lowering the rate of CAUTIs. Since 2010, the Agency for Healthcare Research and Quality (AHRQ) metric has shown a 28.2% decrease in CAUTI, whereas the Centers for Disease Control and Prevention metric has shown a 3%-6% increase in CAUTI since 2009. Differences in data acquisition and the definition of the denominator may explain this discrepancy. The AHRQ metric analyzes chart-audited data and reflects both catheter …

Introduction Next Contents Vol 63(4) Global Research On Ultramafic (Serpentine) Ecosystems (8th International Conference On Serpentine Ecology In Sabah, Malaysia), Antony Van Der Ent, Nishanta Rajakaruna, Robert Boyd, Guillaume Echevarria, Rimi Repin, Dick Williams

Biological Sciences

Since 1991, researchers from approximately 45 nations have participated in eight International Conferences on Serpentine Ecology (ICSE). The ICSE conferences are coordinated by the International Serpentine Ecology Society (ISES), a formal research society whose members study geological, pedological, biological and applied aspects of ultramafic ecosystems worldwide. These conferences have provided an international forum to discuss and synthesise multidisciplinary research, and have provided opportunities for scientists in distinct fields and from different regions of the world to conduct collaborative and interdisciplinary research. The 8th ICSE was hosted by Sabah Parks in Malaysia, on the island of Borneo, and attracted the largest …

A Case Study Exploring Organizational Development And Performance Management In The Operational Infrastructure Of A Professional Working Organization, Using Academic Constructs, Wm. Casey Crear

Electronic Theses and Dissertations

Curriculum, as a concept, has been historically associated with traditional schooling, but the reality is that its application extends to many arenas beyond academia. Through the case study lens, this dissertation utilized the ideologies of curricular theorists John Dewey, John Franklin Bobbitt, and Ralph Tyler to explore how intended, enacted, and assessed curricula phases can integrate into a professional working organization’s comprehensive functionality and materialize into the planning and implementation of its operational infrastructure. Following content analysis of a selected institution’s operational system, using closed codes, a descriptive comprehensive curriculum was designed to address the research purpose of understanding …

Adipokine Levels During The First Or Early Second Trimester Of Pregnancy And Subsequent Risk Of Gestational Diabetes Mellitus: A Systematic Review, Wei Bao, Aileen Baecker, Yiqing Song, Michele Kiely, Simin Liu, Cuilin Zhang

Publications and Research

Objective—We aimed to systematically review available literature linking adipokines to gestational diabetes mellitus (GDM) for a comprehensive understanding of the roles of adipokines in the development of GDM.

Methods—We searched PubMed/MEDLINE and EMBASE databases for published studies on adipokines and GDM through October 21, 2014. We included articles if they had a prospective study design (i.e., blood samples for adipokines measurement were collected before GDM diagnosis). Random-effects models were used to pool the weighted mean differences comparing levels of adipokines between GDM cases and non-GDM controls.

Results—Of 1,523 potentially relevant articles, we included 25 prospective studies relating …

Daily Activity Patterns Of 2,316 Men And Women From Five Countries Differing In Socioeconomic Development, Mamane Sani, Roberto Refinetti

Psychological Sciences Faculty Publications and Presentations

Daily rhythmicity in the locomotor activity of laboratory animals has been studied in great detail for many decades, but the daily pattern of locomotor activity has not received as much attention in humans. We collected waist-worn accelerometer data from more than 2,000 individuals from five countries differing in socioeconomic development and conducted a detailed analysis of human locomotor activity. Body mass index was computed from height and weight. Individual activity records lasting 7 days were subjected to cosinor analysis to determine the parameters of the daily activity rhythm: mesor (mean level), amplitude (half the range of excursion), acrophase (time of …

The Cognition-Enhancing Effects Of Psychostimulants Involve Direct Action In The Prefrontal Cortex, Robert C. Spencer, David M. Devilbiss, Craig Berridge

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Psychostimulants are highly effective in the treatment of attention-deficit/hyperactivity disorder. The clinical efficacy of these drugs is strongly linked to their ability to improve cognition dependent on the prefrontal cortex (PFC) and extended frontostriatal circuit. The procognitive actions of psychostimulants are only associated with low doses. Surprisingly, despite nearly 80 years of clinical use, the neurobiology of the procognitive actions of psychostimulants has only recently been systematically investigated. Findings from this research unambiguously demonstrate that the cognition-enhancing effects of psychostimulants involve the preferential elevation of catecholamines in the PFC and the subsequent activation of norepinephrine α2 and dopamine D1 receptors. …

Effect Of Heat Treatment On The Mechanical Properties In Natural Bamboo, Austin Levy, Mackenzie Kirkpatrick

Materials Engineering

Previous studies have shown that heat treatments have the ability to improve mechanical strength and stiffness in hardwood species. Compared to structural hardwoods, bamboo is a more sustainable and globally viable renewable resource. Therefore, Bambusoides vivax (timber bamboo) culms were fabricated into flat, rectangular cross-section samples with varying cellulose content to be heat treated and tested for mechanical properties. All samples were heat treated (HT) twice. The first HT was a normalization of all samples at 103 +/- 3 °C. The second HT was performed at various times and temperatures ranging from 130°C to 170°C for 0.5 to 3 hours. …

Crossed Mcmurry Coupling Reactions For Porphycenic Macrocycles: Non-Statistical Selectivity And Rationalisation, Thomas Y. Cowie, Lorna Kennedy, Justyna M. Zurek, Martin J. Paterson, Magnus Bebbington

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Crossed McMurry reactions of bifuran- or bithiophenedicarbaldehydes with bipyrroledicarbaldehydes have been studied for the first time. Only those porphycenic macrocycles derived from homocoupled McMurry products were formed. The results are explained by using both density functional theory and electron propagator computations to model the electron affinity of the dialdehyde starting materials. It was predicted that bifuran\bithiophene cross-coupling would indeed occur, and this was demonstrated by the first synthesis of a novel dioxa,dithio hetero-porphycenoid annulene. This approach will allow the prior identification of viable substrates for related crossed McMurry reactions. In the first study of its type, experimental and computational studies …
