The variety was described by Hentschel from the Aru Islands, Stats. 12–14, approximate coordinates 6.2946 – 6.2985 ° S 134.3249– 134.7609°E, depth 15–18 m (14 syntype specimens, SMF 1061–1064). Although Hentschel did not indicate any differences of his variety with the the typical variety of Ridley & Dendy (1886: 327, collected in the Eastern Philippines (Challenger Exped. Stat. 208, 11.6167°N 123.5167°E, depth 33 m, holotype BMNH 1887.5.2.208), it may be deduced from the two descriptions that strongyles in the present variety exceed those of the typical variety in length, 192–280 µm vs. 170 µm in Ridley & Dendy’s material, but Hentschel described also smaller strongyles 64–136 µm long, and he admitted that perhaps intermediate sizes between the larger and smaller strongyles were present. Hentschel’s material was extensive, whereas Ridley & Dendy only had one small fragment, which may explain the more limited spicule size they gave. The differences seem insufficient to justify recognizing a separate taxon for the present species and accordingly I propose to merge the variety into a single, somewhat variable species to be named Petrosia (Petrosia) truncata (Ridley & Dendy, 1886).

Three essays on econometrics
Creators: name: Li, Shiliang
Publisher: name: No Publisher Supplied
Year: 2011

description: The dissertation consists of three independent essays, and they are put in as three chapters. The goal of the first chapter is to develop an estimation procedure for financial time series models with the error terms following the Asymmetric Exponential Power Distribution (AEPD). The AEPD is the most general class of unimodal distributions.  In addition to the usual location and scale parameters, it has skewness and kurtosis parameters. The kurtosis parameter is hard to estimate when the sample size is small and skewness is large.  We show that when the skewness parameter is either close to zero or close to one the estimation of the kurtosis parameters are virtually unidentifiable unless the sample size is  large. We analyze the nonlinear GARCH model (NGARCH) and an asset pricing model known as CKLS.  We devise  Bayesian Markov chain Monte Carlo (MCMC) algorithms. In chapter 2, we focus on econometric computation and develop a method to speed up intensive computation. The combination of MATLAB, C/C++  and Graphic Processing Unit (GPU) is a method to put convenience and speed together. MATLAB is a high level computing language for econometrics.  C/C++ language, on the other hand, is more flexible and more powerful than interpreted languages such as GAUSS, MATLAB and SAS. But it requires more professional programming skills. There are three levels of speedup (within one personal computer). The lowest is simple C++ substitution. The faster level is parallel computing using multicore CPU. The fastest speed-up is parallel computing using GPU cards. The compiled codes which use GPU can run in MATLAB  hundreds time faster than corresponding MATLAB script functions. In chapter 3, we focus on the estimation of the multifactor CKLS model. The CKLS model provides a simple econometric framework  to nest some popular term structure models such as the ones proposed by Merton (1973), Vasicek (1977), and Cox, Ingasol and Ross (CIR) (1985). In this chapter, we provide a new MCMC algorithm to estimate the multifactor CKLS model. Compared to the algorithm in Sowar (2005), our algorithm is more efficient andcan be applied to multifactor models whose dimension is more than two.

Essays on the new Keynesian model
Creators: name: Lee, Seung Moon
Publisher: name: No Publisher Supplied
Year: 2011

description: This dissertation discusses the application, estimation and extension of the New Keynesian macroeconomic model.  Chapter 2 estimates the exchange rate pass-through using Bayesian estimation techniques for Korea and the US. The degree of exchange rate pass-through for Korea is found to increase after the Asian crisis. The nominal rigidity parameter for Korean goods in the foreign countries increased from before the Asian crisis to after the Asian crisis. This suggests that although the important two assumptions on price setting, PCP and LCP, do not hold in this paper, importers in Korea have a stronger tendency to follow the PCP assumption and importers in U.S. have a stronger tendency to follow the LCP for Korean goods after the Asia Crisis. This is consistent with the notion that tradable prices are set in the currency that is most stable.  Chapter 3 introduces the asset market segmentation into an otherwise standard New Keynesian model, and shows that the Taylor principle continues to be essential for macroeconomic stability. In particular, central banks should change nominal interest rates more than one-for-one in response to sustained increases in the inflation rate to guarantee a unique equilibrium. This  nding reverses the results of previous studies that argued the Taylor principle, under asset market segmentation, no longer provides an important criterion for the stability properties of interest rate rules.  Chapter 4 estimates and compares three models, the New Keynesian model with market segmentation, the New Keynesian model with market segmentation and without money, and the standard New Keynesian model with capital, using Bayesian approaches. The posterior mean of parameter fraction of traders for the New Keynesian model with market segmentation is more similar with Landon-Lane and Occhino (2008) than one for the other models. The value of log marginal likelihood, used in evaluating the three models, for the New Keynesian model with market segmentation is the most high of three models.

Regulation of differentiation-specific genes by the Drosophila RB, E2F, and Myb-interacting proteins complex (dREAM)
Creators: name: Lee, Hangnoh
Publisher: name: No Publisher Supplied
Year: 2011

description: RB and E2F proteins play important roles in the regulation of cell division, cell death and development, by controlling the expression of genes involved in these processes.  The mechanisms of repression by pRB have been extensively studied at cell cycle regulated promoters.  However, little is known about developmentally regulated E2F/RB genes.  Here I have taken advantage of the simplicity of the E2F/RB pathway in flies, and inspected the regulation of differentiation-specific target genes. These genes are repressed by dE2F2/RBF and a recently identified RB-containing complex, dREAM, in a cell type- and cell cycle-independent manner. Two different types of activities are involved in their regulation.  First, I find that dREAM employs histone deacetylase (HDAC) activities at promoter regions and that HDACs are required to maintain repression.  Second, I find that the Polycomb Group (PcG) protein, Enhancer of zeste - E(Z), is involved in silencing of these genes through the di-methylation of histone H3 Lys27 at nucleosomes located downstream of the transcription start sites (TSS).  While HDAC activity is also involved in the regulation of cell cycle dependent E2F transcription, E(Z) functions at differentiation-specific target genes only, indicating that the two groups of genes are regulated in a distinct manner. The differentiation-specific genes are also regulated differently from cell cycle-related E2F targets, in a way that they do not depend on E2F-activation.  E2F/RB repression is maintained throughout the cell cycle.  I demonstrated that the dREAM complex is required for dE2F2 binding at differentiation-specific, but not cell cycle-regulated E2F/RB target gene promoters. Especially, dREAM complex is necessary for dE2F2/RBF binding in S-phase. Taking together, my results demonstrate that dREAM plays a dual role in the regulation of differentiation-specific genes. dREAM complex is required for the stability of dE2F2/RBF complexes at these promoters during S-phase, and also for the repression mechanisms employed at these genes.
A semiparametric capital asset pricing model with liquidity and Its application
Creators: name: Lee, Jiyon
Publisher: name: No Publisher Supplied
Year: 2011

description: In this paper, I propose a model that flexibly accounts for liquidity. Extending conventional asset pricing equations, I construct a semiparametric model  that depends on an unknown liquidity function. This function depends on the standard set of liquidity proxies such as bid-ask spread, turnover rate, number of transactions and number of non-trading days. This approach neither imposes any restriction on the structure of liquidity nor limits the number  of proxies which can be associated with liquidity function. The model is estimated by using semiparametric least squares in a time series context and  the estimator is shown to be consistent and asymptotically normal.  In applying this model to stock data we find that the estimated coefficients of bid-ask spread, turnover rate and number of non-trading days are similar in magnitude and are statistically significant. That is, bid-ask spread, turnover rate and number of non-trading days have similar weights in affecting asset returns. Such an outcome implies that missing any of these three variables may significantly change the estimated value of liquidity thus distort the relationship between asset returns and liquidity. The signs of the estimates also support the common belief that bid-ask spread and number of non-trading days are related with the illiquidity cost thus increasing required returns while the other two capture the flexibility in trading. Liquidity impact parameters in construction, manufacturing, wholesale trade and retail industries are statistically significant. The two industries which have the largest liquidity impacts are agriculture, forestry and fishing, and public administration. The companies in these two industries are deemed to have little incentive to smooth out the liquidity level, which induces the second order impacts of the liquidity to be high.
Modeling stakeholder interactions in an international freight  transport system
Creators: name: Lee, Hyangsook
Publisher: name: No Publisher Supplied
Year: 2011

description: This dissertation presents a three-level hierarchical approach which models carrier interactions in international maritime freight transportation networks. Ocean carriers, land carriers and port terminal operators are considered. Port terminal operators, providing transportation services within a port complex, are regarded as a special type of carrier, based on their behavior. The three types of carriers make pricing and routing decisions at different parts of the multimodal network, having hierarchical relationships. Ocean carriers are regarded as the leaders in a maritime shipping market. Port terminal operators are the followers of ocean carriers as well as the leaders of land carriers. The individual carrier problem is formulated at each level using Nash equilibrium in the competitive environment and compensation principle in the collusive environment, respectively. Interactions among different types of carriers are captured in three-level models according to the different carrier environment. Subsequently, shipper-carrier interactions are captured in bi-level models when carriers are the leaders and shippers are the followers. Shippers determine the production, consumption and distribution of goods using spatial price equilibrium. Shippers are users of transportation services, therefore they choose a sequence of carriers based on the carriers’ decisions. The concepts of Stackelberg game and multi-leader-follower game are applied to multi-level games. Heuristic algorithms are developed to solve the carrier and shipper problems. This work contributes to the body of the multimodal freight network problem literature by providing a novel methodology to formulate multi-level hierarchical interaction models. The dissertation assists in understanding of the dynamics and decision-making processes of various stakeholders involved in international freight transportation via waterways.
A strain based topology optimization method

Year: 2011

description: Strain energy based topology optimization method has been used since topology optimization method was presented. Although successful examples from strain energy based topology optimization have been presented, some of the optimal configurations of these designs show stress concentrations or a localized large deformation which is highly undesirable in structure design. In this dissertation, firstly, the strain energy based topology optimization method is reviewed to discover the cause of the problems. Moreover, strain based topology optimization method is presented to avoid these drawbacks. Instead of minimizing strain energy, global effective strain function is minimized. Using this function, compliant mechanism and energy absorbing structure design problems are presented. Since these designs require flexibility and rigidity at the same time, a multi-objective optimization problem is formulated using a physical programming method. Comparisons of design examples from both the strain energy based topology optimization and the proposed method are presented and discussed.  The main contributions of this dissertation are listed as follows: (1)  deriving the sensitivity of the global effective strain, (2)  presenting a complaint mechanism design scheme that can distribute the deformation within the entire mechanism to avoid localized deformation, (3)  formulating energy absorbing function by implementing seek range class function using physical programming method.

Instrumental and sensory characteristics of a baked product containing barley flour with varying amounts of beta-glucan and sugar substitute
Creators: name: Lathia, Niti

Year: 2011

description: The objective of this study was to determine the influence of varying levels of  beta-glucan in barley flour on selected properties of a model baked product. Another aim  was to reduce sugar levels in the product by incorporating a natural sweetener stevia and  to monitor its influence using instrumental and sensory analysis. Batter rheology was  studied using a lubricated squeezing flow technique, pasting profiles of the barley flours  were determined with a rheometer, viscoelastic properties were evaluated using dynamic  oscillatory rheology to measure G’ and G”, and firmness of the baked products was monitored using a texture analyzer, for changes occurring due to varying β-glucan levels  in barley flour and removal of sugar. L a* b* color values of barley flour and muffins  were obtained using a colorimeter. A descriptive sensory panel was trained to observe  changes in product attributes when stevia was used to replace sugar in the high betaglucan  product.    Water absorption index was found to be significantly higher for high β-glucan  barley flour. The color of both barley flours also had a significant difference in L*  (lightness) and b* (yellowness) values. Similarly, muffin samples prepared without  sugar, using stevia, were significantly lighter in surface color (higher L*), while the   interior colors were darker (higher b*). Low beta-glucan dough showed a lower biaxial  extensional viscosity compared to the high beta-glucan dough, which indicates that the  level of beta-glucan present in the barley flour has an impact on the dough viscosity. The  pasting profiles of the flours were also found to be significantly different, where the high  beta-glucan barley flour resulted in a significantly higher peak viscosity but lower peak  time compared to low β-glucan barley flour. Muffin firmness was found to be  significantly higher when sugar was omitted from the formulation, but there was no  significant difference in firmness among the two beta-glucan levels in the muffins. The  sensory descriptive panel found significantly higher firmness, surface roughness, and  bitterness attributes for the high β-glucan muffins prepared with stevia. Additional  efforts will be needed to mask the undesirable attributes in the model baked product  occurring due to the removal of sugar.

Clustering by graph density variation analysis (GDVA) with density-based cluster validity indices (DVI)
Creators: name: Le, Thang Viet
Publisher: name: No Publisher Supplied
Year: 2011

description: Cluster analysis is an important problem in data mining and machine learning. In reality, clustering has been a useful exploratory technique for many different applications such as image segmentation, document grouping, gene expression data analysis, paralog/ortholog detection, etc. Typically, clustering algorithms seek to partition a data set into subsets such that data objects in each subset are very similar, while data objects from different subsets are not so similar. Graph-based clustering methods partition proximity graphs, where nodes represent objects and edge weights indicate pairwise similarities, into subgraphs such that nodes of each subgraph are strongly connected, while nodes of different subgraphs are weakly connected.  This thesis presents a computationally efficient clustering method based on graph density variation analysis, where the density of an object with respect to a set of objects is defined as its average similarity to the objects of the set. The method partitions a proximity graph using the assumption that each cluster has a core region composed of high-density nodes which are strongly interconnected by edges that have a high and comparable weight. Cores of clusters are identified by extracting nodes from the core regions, and then expanded by assigning non-core nodes to the most similar cluster. Novel density-based cluster validity indices are incorporated to measure the quality of clustering solutions so that parameter values can be determined automatically. For a direct and objective evaluation and comparison with other graph clustering techniques, random graphs are generated as input data and the results of clustering are matched against a known ground truth. The method is robust to noise and has a low complexity with two main parameters which can be used to adjust the granularity of results. Experiments show that the method is less dependent on parameters if clusters in the data are well-separated or have a dense cluster core. Good results on heterogeneous data such as multi-dimensional data, images, text and gene expression data demonstrate the effectiveness and versatility of the method.

description: Traumatic brain injury (TBI) results in devastating neurological damage that affects millions of individuals each year. TBI occurs as a result of an external physical insult that leads to mechanical injury followed by a cascade of secondary chemical insults that develop over a period of hours to days, damaging cells and tissue further removed from the initial site of injury.  Often, this secondary injury leads to more significant clinical impairments and may ultimately be the deciding factor in the patient’s recovery.  There remains a tremendous need to develop therapeutics that interfere with secondary injury mechanisms to protect neural function.  The development of appropriate models of TBI is one of the primary hurdles in this field.  Expensive in vivo animal models focus on behavioral endpoints and have resulted in only moderate improvements in patient outcomes.  Most of the current in vitro models of TBI rely on endpoints, such as cell morphology or biochemistry that do not necessarily correlate with cell function.    While preservation of cell number and cell morphology are necessary for a positive outcome after TBI, the cells must also be able to send and receive signals as they did before the injury occurred in order for the central nervous system (CNS) to function properly.  The objective of this thesis is to develop an in vitro model of TBI that can measure changes in the function of cells following injury.  Using microelectrode arrays (MEAs) to study TBI enables one to record the cellular activity before and after injury and with treatment and allows for the measurement of changes in the patterns of electrical activity within the neuronal network, providing a clear picture of not only whether the cells have survived but also how they function.  Our results show that we are able to detect changes in neuronal function that are not detected using simpler in vitro models.  Additionally, we investigated the ability of memantine, an uncompetitive NMDA receptor inhibitor, to protect against secondary injury mechanisms.  Using this tool to screen other potential neuroprotective compounds and identify those that can preserve cell function may translate to better success in animal models.

description: Protoschmidtia foraminosa f. incrustans Czerniavsky, 1880
Protoschmidtia foraminosa f. incrustans Czerniavsky, 1880: 98
Described by Czerniavsky from Sebastopol, Crimea, approximate coordinates 44.62°N 33.5°E (syntypes ZIN-RAS 10962 and 11404). As this is the first mentioned forma it is here chosen as the nominotypical forma to be named P. foraminosa f. foraminosa. As indicated above we propose to merge the forma with the species Haliclona foraminosa (Czerniavsky, 1880).
The present combination is a senior primary homonym of Protoschmidtia grimmi f. incrustans Czerniavsky, 1880: 102. Even though this is currently assigned to the synonymy of Metschnikowia tuberculata Grimm, 1877, the junior name must be replaced (ICZN art. 57.2). I propose Protoschmidtia czerniavskyi nom.nov., which is a junior synonym of Metschnikowia tuberculata Grimm, 1977.

Expression and function of SIRT1, SIRT4, and glutamate dehydrogenase 1 within the central nervous system
Creators: name: Komlos, Daniel

description: Glutamate dehydrogenase 1 (GDH1) reversibly interconverts glutamate and α-ketoglutarate, and although it has shown to have significant importance in metabolic functions within various organ systems, its function within the central nervous system has yet to be fully described. GDH1 is allosterically regulated by many factors, and has been shown to be inhibited by the ADP-ribosyltransferase SIRT4, a mitochondrially localized sirtuin with unknown expression in the brain.    We show that GDH1, along with SIRT4, are mitochondrially localized within the brain, that GDH1 is expressed in astrocytes in the postnatal brain and that SIRT4 is expressed in radial glia during embryonic tissues and appears to decrease in expression during development. We show that in radial glial cell lines, factors known to allosterically regulate GDH1 alter gliogenesis and that SIRT4 and GDH1 overexpression play antagonistic roles in regulating gliogenesis. In addition, an activation mutation of GDH1 accelerates the development of glia from cultured radial glia cells.  When in utero electroporation was performed at E16 and at E19, there was no significant change in neuronal migration at E16+4 however there was a migration defect at E19+4 in those cells overexpressing the activation mutation of GDH1.  These results implicate a role for GDH1 in the development of astrocytes within the CNS.  In the third chapter of this thesis, we show that Sirt1 and HSF1 have important roles in conferring stress resistance and life span extension. Using embryonic neurons and neuroprogenitor cells as models, we show that neuronal differentiation is associated with and facilitated by a decrease in Sirt1 expression, but the maintenance of a basal level of Sirt1 is necessary to prevent apoptotic cell death.    A key down-stream effector of Sirt1 for neuroprotection is HSF1, and we show that the activation and expression of HSF1 and induction of HSP70 are decreased in concomitance with neuron differentiation.    The results demonstrate the divergent and pivotal role of Sirt1 in regulating the differentiation and survival of neuron. Furthermore, we show that a decreased expression of Sirt1 contributes to the attenuated activation of HSF1 and induction of HSP chaperones in the differentiated neuron.

Development of hydrogen-bonding catalysts for the kinetic resolution of amines via anion-binding
Creators: name: Klauber, Eric George
Publisher: name: No Publisher Supplied
Year: 2011

description: Methods development for chiral primary amine synthesis remains a challenge with efficient processes being quite limited. Outlined within this dissertation is the optimization of a bifunctional-hydrogen-bonding catalyzed aldol reaction between imides and aldehydes to produce highly enantioenriched β-hydroxy-α-amino acids.  The main objective for the thesis work is the development of a new anion-binding approach for the kinetic resolution of amines.  In the presence of an achiral nucleophilic co-catalyst, a chiral hydrogen-bonding catalyst, and benzoic anhydride, a chiral ion pair is presumably formed allowing for the efficient resolution of amines.  The major challenges are outlined as well the successful extension to the resolution of benzylic amines.  The work was further expanded to the more synthetically useful propargylic amines, while increasing the overall selectivities by designing and synthesizing a new chiral amide-thiourea catalyst for the study.  Lastly, the more nucleophilic allylic amines were resolved in good selectivities by using PPY as the achiral co-catalyst.
Vitamin A and beta-carotene metabolism during mammalian embryonic development

description: The essential requirement of vitamin A for embryogenesis is well known. The mammalian embryo depends on maternal circulating retinoids (vitamin A and its metabolites) and pro-vitamin A carotenoids, mainly β-carotene, for its supply of vitamin A. The mechanisms through which mammalian developing tissues maintain adequate retinoid levels in the face of suboptimal or excessive maternal dietary vitamin A intake have not been established. Also, whether and how the developing tissues metabolize β- carotene as a “local” source of retinoids is not known.  To address these questions, this study investigated the role of retinyl ester formation catalyzed by lecithin:retinol acyltransferase (LRAT) in regulating retinoid homeostasis during embryogenesis. Also, this study examined the function of β-carotene in maternal-fetal nutrition through the action of its cleavage enzyme, β-carotene 15,15’- oxygenase (CMOI).  We revealed the existence of complex regulatory molecular mechanisms of retinoid homeostasis in embryonic tissues. We showed that, in the case of excessive maternal dietary vitamin A intake, LR acts together with Cyp26A1, one of the enzymes that catalyze the degradation of retinoic acid, and possibly with STRA6, the recently identified cell surface receptor for retinol-RBP, in maintaining adequate levels of retinoids in embryonic and extraembryonic tissues. The contribution of the pathway of retinoic acid synthesis to these regulatory processes becomes significant only under conditions of severe maternal vitamin A deficiency.  In addition, we demonstrated that intact β-carotene can serve as an alternative vitamin A source for the in situ synthesis of retinoic acid (the active form of vitamin A) in the developing tissues by the action of CMOI. Maternally supplemented β-carotene could be delivered to the embryos and the embryonic vitamin A deficiency (VAD) of embryo lacking both CMOI and RBP was improved. In the absence of β-carotene in mouse diets, the observation that lack of CMOI in the RBP knockout developing tissues further exacerbates the severity of VAD was unexpected. Thus, we showed that CMOI exerts an additional function on retinoid metabolism by influencing retinyl ester formation via modulation of LRAT activity, at least in developing tissues.  These findings contributed to expand our knowledge of the molecular basis of maternal-fetal nutrition.

The effects of amodal completion and perceived causality on apparent motion
Creators: name: Kim, Sung-Ho
Publisher: name: No Publisher Supplied
Year: 2011

description: The research presented in this dissertation concerns two ecologically important motion events in the dynamic world: occlusion of moving objects and causal interaction between objects. I investigate how the real-world regularities underlying these events were incorporated as constraints on the percept of underspecified, ambiguous apparent motion; how they constrain the process of interpolating and inferring the most plausible and coherent motion events from apparent motion displays. The first study (Chapter 2) examines whether illusory occlusion of a moving object can bias an apparent motion towards longer curved paths behind an occluder, which would violate the well-established principle that apparent motion follows the shortest possible path. Observers viewed motion sequences of two alternating rectangular targets positioned at the ends of a semicircular “tube,” with varying inter-stimulus intervals (ISIs). The results confirm that curved-path motion can be induced by the presence of the curved occluder. Furthermore, a curved path was most likely with long ISIs, objects less tall and close to the occluder, U-shaped tube occluders, and binocular depth cues, which are consistent with physical plausibility of occlusion. The second study (Chapter 3) investigates whether the path of apparent motion can be influenced by context motion which cues a Michotte-style "launch". The display used in Chapter 3 includes two context objects which appeared to be hit by the motion tokens at their onsets, in the direction of either the straight path or the curved path behind the curved occluder. Subjects in these experiments almost exclusively perceived a motion path in the direction of the launch, regardless of ISI, suggesting a very strong bias in the direction of perceived momentum.  In sum, the results of this dissertation suggest that (1) The amodal representation of a fully hidden object behind an occluder can bridge the gap between two token locations via a curved trajectory so as for the visual system to maintain object persistence, and (2) the launching effect strongly induces a motion path in the direction of launching. The findings provide evidence that apparent motion is perceived in a consistent way with real-world regularities underlying motion events of occlusion and physical collision.
The influence of axiality on figure/ground assignment

description: This study investigates the influence of shape on figure/ground assignment. We measure the influence of axiality -- a measure of how well a shape is described by a skeletal representation -- on border ownership (f/g assignment) by pitting axiality against symmetry, a known figure/ground cue. The axiality is defined via the description length of the maximum a posteriori (MAP) skeleton for a shape. We designed a display in which an axial shape shares a common boundary with a symmetric shape, and used two methods to assess perceived f/g assignment along the common boundary: a local method, the motion probe task, and a global one, an explicit verbal response. Experiment 1, using the motion probe method, found a systematic influence of axiality on border ownership assignment: the shape with stronger axiality tends more often to be perceived as figure, that is, to own the common boundary. The results from Experiment 2 confirm that such effect of axiality was consistent for global f/g assignment as well. We conclude that (a) the axiality has an influence on f/g assignment, so global (from all contour points) and local (only near the motion probe) axialties of shapes predict border ownership, and (b) the contour of the shared boundary is perceptually "owned" by the skeleton that best explains the shape.
