Multiobjective Optimization For Complex Systems, Melissa Gardenghi Aug 2009

Multiobjective Optimization For Complex Systems, Melissa Gardenghi

All Dissertations

Complex systems are becoming more and more apparent in a variety of disciplines, making solution methods for these systems valuable tools. The solution of complex systems requires two significant skills. The first challenge of developing mathematical models for these systems is followed by the difficulty of solving these models to produce preferred solutions for the overall systems. Both issues are addressed by this research.
This study of complex systems focuses on two distinct aspects. First, models of complex systems with multiobjective formulations and a variety of structures are proposed. Using multiobjective optimization theory, relationships between the efficient solutions of the …

Assessment Of Invasive Plants Along The Upper Passaic River, Susan Marie Jankovic Aug 2009

Assessment Of Invasive Plants Along The Upper Passaic River, Susan Marie Jankovic

Theses, Dissertations and Culminating Projects

The distribution of invasive plants was determined along the floodplain of the Passaic River in three protected park regions. Specifically, Lord Stirling Park, Hatfield Swamp, and Great Piece Meadows were assessed to determine whether or not the top 29 invasive plants as identified by Snyder and Kaufman (2004) were present. Two of the three areas are strongly affected by urbanization which may be a contributing factor to the increase of invasive plants within them. Eleven out of the top twenty nine invasive plants in New Jersey were recorded: Multiflora rose (Rosa multiflora), Lesser celandine (Ranunculus ficaria), Japanese stiltgrass (Microstegium vimineum), …

Biology & Environmental Sciences Faculty Publications

The success of clinically relevant immunotherapies requires reversing tumor-induced immunosuppression. Here we demonstrated that linear polyethylenimine-based (PEI-based) nanoparticles encapsulating siRNA were preferentially and avidly engulfed by regulatory DCs expressing CD11c and programmed cell death 1–ligand 1 (PD-L1) at ovarian cancer locations in mice. PEI-siRNA uptake transformed these DCs from immunosuppressive cells to efficient antigen-presenting cells that activated tumor-reactive lymphocytes and exerted direct tumoricidal activity, both in vivo and in situ. PEI triggered robust and selective TLR5 activation in vitro and elicited the production of hallmark TLR5-inducible cytokines in WT mice, but not in Tlr5–/– littermates. Thus, PEI is a TLR5 …

Phylogeny And Phylogenetic Classification Of The Antbirds, Ovenbirds, Woodcreepers, And Allies (Aves: Passeriformes: Infraorder Furnariides), Robert G. Moyle, R. Terry Chesser, Robb T. Brumfield, Jose G. Tello, Daniel J. Marchese, Joel Cracraft

Faculty Publications

The infraorder Furnariides is a diverse group of suboscine passerine birds comprising a substantial component of the Neotropical avifauna. The included species encompass a broad array of morphologies and behaviours, making them appealing for evolutionary studies, but the size of the group (ca. 600 species) has limited well-sampled higher-level phylogenetic studies. Using DNA sequence data from the nuclear RAG-1 and RAG-2 exons, we undertook a phylogenetic analysis of the Furnariides sampling 124 (more than 88%) of the genera. Basal relationships among family-level taxa differed depending on phylogenetic method, but all topologies had little nodal support, mirroring the results from earlier …

Outdoor Adventures, Self-Efficacy, And Proactive Work Behaviors, Jennifer Hopkins Aug 2009

Outdoor Adventures, Self-Efficacy, And Proactive Work Behaviors, Jennifer Hopkins

Masters Theses and Doctoral Dissertations

The modern work environment is characterized by continuous changes involving mergers, acquisitions, downsizing, and organizational restructuring. To persevere in this context, employees are now implicitly required to demonstrate more proactivity when carrying out their job functions. Although proactive work behaviors seem to predict career and organizational achievement, relatively little research has examined the underlying process that stimulates such behaviors in employees. The present research addressed this gap by testing the hypothesis that the positive relationship between successful completion of an outdoor adventure training (OA) program and future proactive work behaviors is mediated by a person’s self-efficacy. Two studies were conducted; …

Gender And Ptsd: What Can We Learn From Female Police Officers?, Michelle M. Lilly, Nnamdi Pole, Suzanne R. Best, Thomas Metzler, Charles R. Marmar Aug 2009

Gender And Ptsd: What Can We Learn From Female Police Officers?, Michelle M. Lilly, Nnamdi Pole, Suzanne R. Best, Thomas Metzler, Charles R. Marmar

Psychology: Faculty Publications

Studies of civilians typically find that female gender is a risk factor for posttraumatic stress disorder (PTSD). Police and military studies often find no gender differences in PTSD. We compared 157 female police officers and 124 female civilians on several variables including trauma exposure, peritraumatic emotional distress, current somatization, and cumulative PTSD symptoms. We found that despite greater exposure to assaultive violence in the officer group, female civilians reported significantly more severe PTSD symptoms. Elevated PTSD symptoms in female civilians were explained by significantly more intense peritraumatic emotional distress among female civilians. We also found that female officers showed a …

Pharmaceutical Sciences Faculty Publications

Signal transducer and activator of transcription 3 (STAT3) is aberrantly activated in human cancer including lung cancer and has been implicated in transformation, tumorigenicity, and metastasis. One putative downstream gene regulated by Stat3 is MUC1 which also has important roles in tumorigenesis. We determined if Stat3 regulates MUC1 in lung cancer cell lines and what function MUC1 plays in lung cancer cell biology. We examined MUC1 expression in non-small cell lung cancer (NSCLC) cell lines and found high levels of MUC1 protein expression associated with higher levels of tyrosine phosphorylated STAT3. STAT3 knockdown downregulated MUC1 expression whereas constitutive STAT3 expression …

Continued Development Of An Empirical Function For Predicting And Rationalizing Protein–Protein Binding Affinities, Joseph Audie Aug 2009

Continued Development Of An Empirical Function For Predicting And Rationalizing Protein–Protein Binding Affinities, Joseph Audie

Chemistry & Physics Faculty Publications

Here we summarize recent work on the continued development of our fast and simple empirical equation for predicting and structurally rationalizing protein–protein and protein–peptide binding affinities. Our empirical expression consists of six regression-weighted physical descriptors and derives from two key simplifying assumptions: (1) the assumption of rigid-body association and (2) the assumption that all contributions not explicitly considered in the equation make a net contribution to binding of ≈0 kcal. Within the strict framework of rigid-body association, we tested relative binding affinity predictions using our empirical equation against the corresponding experimental binding free energy data for 197 interface alanine mutants. …

Robert Munford & Mercy Otis Warren : How Gender, Geography, And Goals Affected Their Playwrighting, Kylie A. Horney

Master's Theses

This thesis analyzes the Revolutionary-era plays of Robert Munford and Mercy Otis Warren. Munford’s two comedies, The Candidates and The Patriots, are compared to Warren’s three earliest satires, The Adulateur, The Defeat, and The Group, in an effort to explain some of the differences between these two authors. The original printings of these plays from the Early American Imprints series, as well as more recent scholarship on Munford and Warren, are used to investigate the plays and lives of these playwrights. Munford’s and Warren’s backgrounds are explored to account for variations in their works. While the …

Looking Into The Mind Of The Mother : Pup Exposure And Reactivation Of Maternal Circuits, Tricia Lauren Norkunas Aug 2009

Looking Into The Mind Of The Mother : Pup Exposure And Reactivation Of Maternal Circuits, Tricia Lauren Norkunas

Master's Theses

The female rat, among other species, undergoes a fundamental brain re-modeling as a consequence of experiencing the normal and natural events of pregnancy and offspring stimulation. Compelling data show that maternal experiences produce neurobiological modifications in the female leading to specific maternal behaviors, affective states, and the basic underlying female neurobiology necessary to raise viable offspring. This study aims to evaluate the number, quality and selective activation of neurons that develop during the maternal experience. The study showed a trend toward supporting the hypothesis that a “maternal-circuit” is formed through the proliferation of neurons during late-motherhood and lactation, and is …

Insulin Stimulates The Phosphorylation Of The Exocyst Protein Sec8 In Adipocytes, Patrick D. Lyons, Grantley R. Peck, Arminja N. Kettenbach, Scott A. Gerber, Liya Roudaia, Gustav E. Lienhard Aug 2009

Insulin Stimulates The Phosphorylation Of The Exocyst Protein Sec8 In Adipocytes, Patrick D. Lyons, Grantley R. Peck, Arminja N. Kettenbach, Scott A. Gerber, Liya Roudaia, Gustav E. Lienhard

Dartmouth Scholarship

The signal transduction pathway leading from the insulin receptor to stimulate the fusion of vesicles containing the glucose transporter GLUT4 with the plasma membrane in adipocytes and muscle cells is not completely understood. Current evidence suggests that in addition to the Rab GTPase-activating protein AS160, at least one other substrate of Akt (also called protein kinase B), which is as yet unidentified, is required. Sec8 is a component of the exocyst complex that has been previously implicated in GLUT4 trafficking. In the present study, we report that insulin stimulates the phosphorylation of Sec8 on Ser-32 in 3T3-L1 adipocytes. On the …

Triticum Mosaic Virus: A Distinct Member Of The Family Potyviridae With An Unusually Long Leader Sequence, Satyanarayana Tatineni, Amy D. Ziems, Stephen N. Wegulo, Roy French

Department of Plant Pathology: Faculty Publications

The complete genome sequence of Triticum mosaic virus (TriMV), a member in the family Potyviridae, has been determined to be 10,266 nucleotides (nt) excluding the 3′ polyadenylated tail. The genome encodes a large polyprotein of 3,112 amino acids with the “hall-mark proteins” of potyviruses, including a small overlapping gene, PIPO, in the P3 cistron. The genome of TriMV has an unusually long 5′ nontranslated region of 739 nt with 12 translation initiation codons and three small open reading frames, which resemble those of the internal ribosome entry site containing 5′ leader sequences of the members of Picornaviridae. Pairwise …

Response To Plevin: Implications For Life Cycle Emissions Regulations, Adam Liska, Kenneth G. Cassman Aug 2009

Response To Plevin: Implications For Life Cycle Emissions Regulations, Adam Liska, Kenneth G. Cassman

Nebraska Center for Energy Sciences Research: Publications

A robust dialogue concerning appropriate parameter values for life cycle assessment (LCA) models is necessary because regulation of life cycle greenhouse gas (GHG) emissions from biofuel systems will determine market access and government subsidies for biofuel producers.1 Such a dialogue is also critical for creating more accurate LCA methods that will be accepted by scientists, industry, and the public. Plevin (2009) has identified multiple concerns with the life cycle emissions methodology employed in our previous analysis using the Biofuel Energy Systems Simulator (BESS) model (Liska et al. 2009), but only four alter our estimates substantially: (1) denaturant addition (+6.5 gCO …
