description: We report contributions to cosmic infrared background (CIB) intensities originating from known galaxies and their faint companions at submillimeter wavelengths. Using the publicly-available UltraVISTA catalog, and maps at 250, 350, and 500 μm from the \emph{Herschel} Multi-tiered Extragalactic Survey (HerMES), we perform a novel measurement that exploits the fact that uncatalogued sources may bias stacked flux densities --- particularly if the resolution of the image is poor --- and intentionally smooth the images before stacking and summing intensities. By smoothing the maps we are capturing the contribution of faint (undetected in K_S ~ 23.4) sources that are physically associated, or correlated, with the detected sources. We find that the cumulative CIB increases with increased smoothing, reaching 9.82 +- 0.78, 5.77 +- 0.43, and 2.32 +- 0.19$\, \rm nW m^{-2} sr^{-1}$ at 250, 350, and 500 μm at 300 arcsec FWHM. This corresponds to a fraction of the fiducial CIB of 0.94 +- 0.23, 1.07 +- 0.31, and 0.97 +- 0.26 at 250, 350, and 500 μm, where the uncertainties are dominated by those of the absolute CIB. We then propose, with a simple model combining parametric descriptions for stacked flux densities and stellar mass functions, that emission from galaxies with log(M/Msun) > 8.5 can account for the most of the measured total intensities, and argue against contributions from extended, diffuse emission. Finally, we discuss prospects for future survey instruments to improve the estimates of the absolute CIB levels, and observe any potentially remaining emission at z > 4.

description: We compute the two-mass contributions to the polarized massive operator matrix element $A_{gg,Q}^{(3)}$ at third order in the strong coupling constant $\alpha_s$ in Quantum Chromodynamics analytically. These corrections are important ingredients for the matching relations in the variable flavor number scheme and for the calculation of Wilson coefficients in deep--inelastic scattering in the asymptotic regime $Q^2 \gg m_c^2, m_b^2$. The analytic result is expressed in terms of nested harmonic, generalized harmonic, cyclotomic and binomial sums in $N$-space and by iterated integrals involving square-root valued arguments in $z$ space, as functions of the mass ratio. Numerical results are presented. New two--scale iterative integrals are calculated.

description: The objective of this paper is to establish a master plan based on a systematic and strategic approach to implement a sound environment-friendly agriculture in Jinan-gun, Jeollabuk-do. In order to establish the master plan, we conducted a survey to collect the opinions of both conventional and environment-friendly farming practicing farmers and examined the accounting balance of regional nutrients to analyze the regional-based environmental carrying capacity. The analysis results suggest a systematic and stepwise promotion plan with three stages: infrastructure construction stage (2008-2010), take-off stage (2011-2015), and sustainable development stage (2015-2020) with the overall long-term plan targeted at 2020.

description: Why diversification rates vary so extensively across the tree of life remains an important yet unresolved issue in biology. Two prominent and potentially independent factors proposed to explain these trends reflect the capacity of lineages to expand into new areas of (i) geographical or (ii) ecological space. Here, we present the first global assessment of how diversification rates vary as a consequence of geographical and ecological expansion, studying these trends among 15 speciose passerine families (together approximately 750 species) using phylogenetic path analysis. We find that relative slowdowns in diversification rates characterize families that have accumulated large numbers of co-occurring species (at the 1° scale) within restricted geographical areas. Conversely, more constant diversification through time is prevalent among families in which species show limited range overlap. Relative co-occurrence is itself also a strong predictor of ecological divergence (here approximated by morphological divergence among species); however, once the relationship between co-occurrence and diversification rates have been accounted for, increased ecological divergence is an additional explanatory factor accounting for why some lineages continue to diversify towards the present. We conclude that opportunities for prolonged diversification are predominantly determined by continued geographical range expansion and to a lesser degree by ecological divergence among lineages.

description: Inhibition of protein-tyrosine phosphatases (PTPs) counterbalancing protein-tyrosine kinases (PTKs) offers a strategy for augmenting PTK actions. Conservation of PTP catalytic sites limits development of specific PTP inhibitors. A number of receptor PTPs, including the leukocyte common antigen-related (LAR) receptor and PTPmu, contain a wedge-shaped helix-loop-helix located near the first catalytic domain. Helix-loop-helix domains in other proteins demonstrate homophilic binding and inhibit function; therefore, we tested the hypothesis that LAR wedge domain peptides would exhibit homophilic binding, bind to LAR, and inhibit LAR function. Fluorescent beads coated with LAR or PTPmu wedge peptides demonstrated PTP-specific homophilic binding, and LAR wedge peptide-coated beads precipitated LAR protein. Administration of LAR wedge Tat peptide to PC12 cells resulted in increased proliferation, decreased cell death, increased neurite outgrowth, and augmented Trk PTK-mediated responses to nerve growth factor (NGF), a phenotype matching that found in PC12 cells with reduced LAR levels. PTPmu wedge Tat peptide had no effect on PC12 cells but blocked the PTPmu-dependent phenotype of neurite outgrowth of retinal ganglion neurons on a PTPmu substrate, whereas LAR wedge peptide had no effect. The survival- and neurite-promoting effect of the LAR wedge peptide was blocked by the Trk inhibitor K252a, and reciprocal co-immunoprecipitation demonstrated LAR/TrkA association. The addition of LAR wedge peptide inhibited LAR co-immunoprecipitation with TrkA, augmented NGF-induced activation of TrkA, ERK, and AKT, and in the absence of exogenous NGF, induced activation of TrkA, ERK, and AKT. PTP wedge domain peptides provide a unique PTP inhibition strategy and offer a novel approach for augmenting PTK function.
Impurity Effects on Bound States in the Vortex Core of Topological S-wave Superconductor

description: We study the impurity effects on the Caroli-de Gennes-Matricon (CdGM) states, particularly on the level spacings in a vortex core in topological s-wave superconductor (SC) by two means, numerically and analytically. The topological s-wave SC belongs to the same class as a chiral p-wave SC and thus there are two inequivalent vortices in terms of any symmetry operation. We take into account this inequivalence and numerically calculate the scattering rates based on an improved version of Kopnin-Kravtsov (iKK) scheme, which enables us to treat the discrete levels in the presence of white-noise disorder. We also construct the Andreev equation for the topological s-wave SC and obtain the Andreev bound states analytically. We use a correspondence between the wave functions for the Bogoliubov-de Gennes equation and the Andreev equation in the iKK scheme and deduce the formula of scattering rates described by the wave function for the Andreev equation. With this formula, we discuss the origin of impurity scattering rates for CdGM states of topological s-wave SC and the dependence on the types of vortices related to the inequivalence.

description: Dark Matter (DM) may be a thermal relic that annihilates into heavier states in the early Universe. This Forbidden DM framework accommodates a wide range of DM masses from keV to weak scales. An exponential hierarchy between the DM mass and the weak scale follows from the exponential suppression of the thermally averaged cross section. Stringent constraints from the cosmic microwave background are evaded because annihilations turn off at late times. We provide an example where DM annihilates into dark photons, which is testable through large DM self-interactions and direct detection.

description: Long chain acyl-CoA synthetase (ACSL) catalyzes the initial step in long chain fatty acid metabolism. Of the five mammalian ACSL isoforms cloned and characterized, ACSL5 is the only isoform found to be located, in part, on mitochondria and thus was hypothesized to be involved in fatty acid oxidation. To elucidate the specific roles of ACSL5 in fatty acid metabolism, we used adenoviral-mediated overexpression of ACSL5 (Ad-ACSL5) in rat hepatoma McArdle-RH7777 cells. Confocal microscopy revealed that Ad-ACSL5 colocalized to both mitochondria and endoplasmic reticulum. When compared with cells infected with Ad-GFP, Ad-ACSL5-infected cells at 24 h after infection had 2-fold higher acyl-CoA synthetase activities and 30% higher rates of fatty acid uptake when incubated with 500 microM [1-(14)C]oleic acid. Metabolism of [1-(14)C]oleic acid to cellular triacylglycerol (TAG) increased 42% in Ad-ACSL5-infected cells, but when compared with control cells, metabolism to acid-soluble metabolites, phospholipids, and medium TAG did not differ substantially. The incorporation of [1-(14)C]oleate and [1,2,3-(3)H]glycerol into TAG was similar in Ad-ACSL5-infected cells, thus indicating that Ad-ACSL5 increased TAG synthesis through both de novo and reacylation pathways. However, [1-(14)C]acetic acid incorporation into cellular lipids showed that, when compared with control cells, Ad-ACSL5-infected cells did not increase the metabolism of fatty acids that were derived from de novo synthesis. These results suggest that uptake of fatty acids into cells is regulated by metabolism and that overexpressed ACSL5 partitions exogenously derived fatty acids toward TAG synthesis and storage.

description: Cell-cell adhesion is critical to the development and maintenance of multicellular organisms. The stability of many adhesions is regulated by protein tyrosine phosphorylation of cell adhesion molecules and their associated components, with high levels of phosphorylation promoting disassembly. The level of tyrosine phosphorylation reflects the balance between protein-tyrosine kinase and protein-tyrosine phosphatase activity. Many protein-tyrosine phosphatases associate with the cadherin-catenin complex, directly regulating the phosphorylation of these proteins, thereby affecting their interactions and the integrity of cell-cell junctions. Tyrosine phosphatases can also affect cell-cell adhesions indirectly by regulating the signaling pathways that control the activities of Rho family G proteins. In addition, receptor-type tyrosine phosphatases can mediate outside-in signaling through both ligand binding and dimerization of their extracellular domains. This review will discuss the role of protein-tyrosine phosphatases in cell-cell interactions, with an emphasis on cadherin-mediated adhesions.

description: Using an effective field theory approach and the language of SU(N)-structures, we study higher derivative corrections to the supersymmetry constraints for compactifications of string or M-theory to Minkowski space. Our analysis is done entirely in the target space and is thus very general, and does not rely on theory-dependent details such as the amount of worldsheet supersymmetry. For manifolds of real dimension n<4 we show that the internal geometry remains flat and uncorrected. For n=4, 6, Kahler manifolds with SU(N)-holonomy can become corrected to SU(N)-structure, while preserving supersymmetry, once corrections are included.

description: This thesis contributes to a better understanding of the method of model predictive control (MPC) for time-varying systems. Time-varying systems are used to describe physical phenomena in numerous technical applications. The interior temperature of a building can, for example, be described by such a time-varying system because it is influenced by the daily and nightly fluctuations of the outside temperature and the weather. MPC can be used to compute efficient operating strategies of buildings (i.e. when to heat or to cool) and thereby reduce overall energy consumption. With regard to the urgently needed reduction of CO2 emissions in the building sector, a deeper understanding of this method is indispensable to develop more powerful algorithms. In time-varying systems, optimal system behavior can generally be very complex and, in particular, does not have to occur at an equilibrium or periodic trajectory. This makes it necessary to adequately characterize optimal trajectories in the time-varying setting, which is achieved by considering a modified notion of optimality. Based on this, conditions are derived under which the cost of the MPC closed-loop are approximately optimal, i.e. almost equal to the costs of an optimal solution trajectory on infinite time horizon. For a sufficiently large MPC horizon length, the optimal system behavior can in principle be approximated arbitrarily well. In this context, the so-called turnpike property and a continuity property of the optimal value function are of particular importance. In addition, it is shown that under the additional assumption of strict dissipativity the MPC trajectory tends towards the vicinity of an optimal operating trajectory. Furthermore, it is examined whether the assumptions made are reasonable and can be explicitly proven or observed in simulations for systems in practice. For this purpose, central results of the work are illustrated by the example of a convection-diffusion equation. Moreover, two methods for optimal control of variations of this equation are presented. Finally, a performance estimator for time-invariant MPC is presented, which serves to monitor the controller performance at run-time.

description: Inosine monophosphate dehydrogenase (IMPDH), a rate-limiting enzyme in the de novo synthesis of guanine nucleotides, is a major therapeutic target. A prototypic uncompetitive inhibitor of IMPDH, mycophenolic acid (MPA), is the active form of mycophenolate mofeteil (CellCept), a widely used immunosuppressive drug. We have found that MPA interacts with intracellular IMPDH in vivo to alter its mobility on SDS-polyacrylamide gels. MPA also induces a striking conformational change in IMPDH protein in intact cells, resulting in the formation of annular aggregates of protein with concomitant inhibition of IMPDH activity. These aggregates are not associated with any known intracellular organelles and are reversible by incubating cells with guanosine, which repletes intracellular GTP, or with GTPgammaS. GTP also restores IMPDH activity. Treatment of highly purified IMPDH with MPA also results in the formation of large aggregates of protein, a process that is both prevented and reversed by the addition of GTP. Finally, GTP binds to IMPDH at physiologic concentrations, induces the formation of linear arrays of tetrameric protein, and prevents the aggregation of protein induced by MPA. We conclude that intracellular GTP acts as an antagonist to MPA by directly binding to IMPDH and reversing the conformational changes in the protein.
Rho Kinase Differentially Regulates Phosphorylation of Nonmuscle Myosin II Isoforms A and B during Cell Rounding and Migration

description: The actin-myosin cytoskeleton is generally accepted to produce the contractile forces necessary for cellular processes such as cell rounding and migration. All vertebrates examined to date are known to express at least two isoforms of non-muscle myosin II, referred to as myosin IIA and myosin IIB. Studies of myosin IIA and IIB in cultured cells and null mice suggest that these isoforms perform distinct functions. However, how each myosin II isoform contributes individually to all the cellular functions attributed to "myosin II" has yet to be fully characterized. Using isoform-specific small-interfering RNAs, we found that depletion of either isoform resulted in opposing migration phenotypes, with myosin IIA- and IIB-depleted cells exhibiting higher and lower wound healing migration rates, respectively. In addition, myosin IIA-depleted cells demonstrated impaired thrombin-induced cell rounding and undertook a more motile morphology, exhibiting decreased amounts of stress fibers and focal adhesions, with concomitant increases in cellular protrusions. Cells depleted of myosin IIB, however, were efficient in thrombin-induced cell rounding, displayed a more retractile phenotype, and maintained focal adhesions but only in the periphery. Last, we present evidence that Rho kinase preferentially regulates phosphorylation of the regulatory light chain associated with myosin IIA. Our data suggest that the myosin IIA and IIB isoforms are regulated by different signaling pathways to perform distinct cellular activities and that myosin IIA is preferentially required for Rho-mediated contractile functions.

description: A high fidelity amplification of beams carrying orbital angular momentum (OAM) is very crucial for OAM multiplexing and other OAM-based applications. Here, we report the first study of stimulated Brillouin amplification (SBA) for OAM beams, the energy conversion efficiency of photon-phonon coupling and the phase structure of amplified signals are investigated in collinear and noncollinear frame systems, respectively. Our results demonstrate that the OAM signals can be efficiently amplified without obvious noise introduced, and the modes of output signal are independent of the pump modes or the geometrical frames. Meanwhile, an OAM state depending on the optical modes and the geometrical frames is loaded into phonons by coherent light-acoustic interaction, which reveals more fundamental significance and a great application potential in OAM-multiplexing.

description: Using the spectral energy distribution of M87, a nearby radio galaxy in the Virgo cluster, and assuming a supermassive black hole induced spike in the dark matter halo profile, we exclude any dark matter candidate with a velocity-independent (s-wave) annihilation cross-section of the order of sigma v ~ 10^{-26} cm^3/s and a mass up to O(100) TeV. These limits supersede all previous constraints on thermal, s-wave, annihilating dark matter candidates by orders of magnitude, and rule out the entire canonical mass range. We remark in addition that, under the assumption of a spike, dark matter particles with a mass of a few TeV and an annihilation cross-section of ~ 10^{-27} cm^3/s could explain the TeV gamma-ray emission observed in M87. A central dark matter spike is plausibly present around the supermassive black hole at the center of M87, for various, although not all, formation scenarios, and would have profound implications for our understanding of the dark matter microphysics.

description: It is often said that there are too many brands of environmentally-friendly agricultural products, and that is one of the reasons why the premiums for those goods are low in Korea. The Paldang Clean Agricultural Belt Project is a Gyounggi Province's project that aims at extending the share of environmentally friendly farming in the 7 cities surrounding the Paldang Lake which is almost the only drinking-water source of Seoul Metropolitan Area. Although the primary goal of the project is contributing to the improvement of water quality in the lake, the project contains various steps to promote marketing of environmentally-friendly goods produced in the region. One of the strategies suggested is merging the existing small scale brands into one which is named “Paldang Seon (the gift from Paldang)” The paper investigates whether and how much consumers will pay more for the new large scale brands whose quality will be guaranteed by the Province. The differences in WTPs for the regular goods, the existing brands, and the Paldang Seon are estimated with a bivariate probit model as well as a contingent ranking model applied to a survey data set. It is found that the size of the additional WTP for the new brand differs by product-type substantially. For the cases of rice and fruits there are already well-known national level brands, and the WTPs for the larger scale brands are small. However, the WTPs for fresh vegetables and eggs where most brands are small-sized will increase substantially when the existing brands are merged into a larger one.

description: O-Glycosylation modifies and regulates a variety of intracellular proteins. Plakoglobin, which functions in both cell-cell adhesion and signal transduction, is modified by O-glycosylation; however, the significance is unknown. To investigate the functional consequence of plakoglobin O-glycosylation, we cloned and overexpressed in keratinocytes murine O-GlcNAc transferase (mOGT). Over expression of mOGT in murine keratinocytes resulted in (i) glycosylation of plakoglobin and (ii) increased levels of plakoglobin due to post-translational stabilization of plakoglobin. Additionally, overexpression of mOGT in keratinocytes correlated with increased staining for cell-cell adhesion proteins and greater cell-cell adhesion. These observations suggest that O-glycosylation functions to regulate the post-translational stability of plakoglobin and keratinocyte cell-cell adhesion.

description: During mRNA elongation, the SRI domain of the histone H3 methyltransferase Set2 binds to the phosphorylated carboxyl-terminal domain (CTD) of RNA polymerase II. The solution structure of the yeast Set2 SRI domain reveals a novel CTD-binding fold consisting of a left-handed three-helix bundle. NMR titration shows that the SRI domain binds an Ser2/Ser5-phosphorylated CTD peptide comprising two heptapeptide repeats and three flanking NH2-terminal residues, whereas a single CTD repeat is insufficient for binding. Residues that show strong chemical shift perturbations upon CTD binding cluster in two regions. Both CTD tyrosine side chains contact the SRI domain. One of the tyrosines binds in the region with the strongest chemical shift perturbations, formed by the two NH2-terminal helices. Unexpectedly, the SRI domain fold resembles the structure of an RNA polymerase-interacting domain in bacterial sigma factors (domain sigma2 in sigma70).

description: We initiate the study of correspondences for Smale spaces. Correspondences are shown to provide a notion of a generalized morphism between Smale spaces and are a special case of finite equivalences. Furthermore, for shifts of finite type, a correspondence is related to a matrix which intertwines the adjacency matrices of the shifts. This observation allows us to define an equivalence relation on all Smale spaces which reduces to shift equivalence for shifts of finite type. Several other notions of equivalence are introduced on both correspondences and Smale spaces; a hierarchy between these equivalences is established. Finally, we provide several methods for constructing correspondences and provide specific examples.

description: Polycomb group (PcG) proteins Bmi-1 and Ring1B are core subunits of the PRC1 complex which plays important roles in the regulation of Hox gene expression, X-chromosome inactivation, tumorigenesis and stem cell self-renewal. The RING finger protein Ring1B is an E3 ligase that participates in the ubiquitination of lysine 119 of histone H2A, and the binding of Bmi-1 stimulates the E3 ligase activity. We have mapped the regions of Bmi-1 and Ring1B required for efficient ubiquitin transfer and determined a 2.5 Angstroms structure of the Bmi-1-Ring1B core domain complex. The structure reveals that Ring1B 'hugs' Bmi-1 through extensive RING domain contacts and its N-terminal tail wraps around Bmi-1. The two regions of interaction have a synergistic effect on the E3 ligase activity. Our analyses suggest a model where the Bmi-1-Ring1B complex stabilizes the interaction between the E2 enzyme and the nucleosomal substrate to allow efficient ubiquitin transfer.

description: For the periodic sphaleron potential in the electroweak theory, we find the one-dimensional time-independent Schrödinger equation with the Chern-Simons number as the coordinate, construct the Bloch wave function and determine the corresponding conducting (pass) band structure. We show that the baryon-lepton number violating processes can take place without the exponential tunneling suppression (at zero temperature) at energies around and above the barrier height (sphaleron energy) at 9.0 TeV. Phenomenologically, probable detection of such processes at LHC is discussed.

Contested evidence: visual representations of border violence in Calais, France

description: This thesis discusses the visual representation of violence and asks how practices of evidencing that are supposed to challenge the border can also be interpreted as constructing it. Through participation in practices of evidencing border violence in Calais, France, and using De Genova's 'border spectacle' as a theory of the dominant framing of border violence, this thesis investigates how representations of violence can be incorporated into presiding narratives of 'illegal' migration. It also argues that through a consideration of the discourse of vulnerability visual documentation can be used as a tool to resist movement restrictions, challenging the dominant framing of violence that is exemplified by the theory of the border spectacle. The visual material analysed in this thesis documents three forms of violence; police violence, anti-immigrant vigilante violence, and protest violence. Examining the way that evidence of these forms of violence is contested demonstrates how representations of violence can construct the figure of the 'illegal' migrant, and conversely how they can also be used to challenge the dominant framing of border violence. Deploying a movement-based epistemology and using forensic investigation as a method of analysis, this interdisciplinary investigation into the collection, collation and publication of evidence of violence utilises approaches and methods from the visual arts, critical border studies, and social movement studies. Drawing on a period of extended field work in Calais, which involved participation in the production and publication of the evidential material analysed, it examines how violence is represented by different mediators. With a consideration of specific practices of producing evidence, it investigates how visual representations of violence are mobilised by various actors within the struggle against movement restrictions. This thesis contributes to knowledge by examining the applicability of the theory of the border spectacle for explaining practices of evidencing border violence.

description: The luminous Class I protostar HBC 494, embedded in the Orion A cloud, is associated with a pair of reflection nebulae, Re50 and Re50N, which appeared sometime between 1955 and 1979. We have found that a dramatic brightening of Re50N has taken place sometime between 2006 and 2014. This could result if the embedded source is undergoing a FUor eruption. However, the near-infrared spectrum shows a featureless very red continuum, in contrast to the strong CO bandhead absorption displayed by FUors. Such heavy veiling, and the high luminosity of the protostar, is indicative of strong accretion but seemingly not in the manner of typical FUors. We favor the alternative explanation that the major brightening of Re50N and the simultaneous fading of Re50 is caused by curtains of obscuring material that cast patterns of illumination and shadows across the surface of the molecular cloud. This is likely occurring as an outflow cavity surrounding the embedded protostar breaks through to the surface of the molecular cloud. Several Herbig-Haro objects are found in the region.

description: Histone methylation plays an important role in chromatin dynamics and gene expression. Methylation of histone H3-lysine 27 by the EZH2 complex has been linked to the silencing of homeotic genes and the inactivation of the X chromosome. Here we report a characterization of the substrate preferences of the enzyme complex using a reconstituted chromatin and enzyme system. We found that the linker histone H1, when incorporated into nucleosomes, stimulates the enzymatic activity toward histone H3. This stimulatory activity may be explained by protein-protein interactions between H1 and components of the EZH2 complex. In addition, we found that the EZH2 complex exhibits a dramatic preference for dinucleosomes when compared with mononucleosomes and that the stimulation of H3 methylation by H1 requires dinucleosomes or oligonucleosome substrates. Furthermore, in contrast with a recent study suggesting that Embryonic Ectoderm Development EED isoforms may affect substrate specificity, we found that EZH2 complexes reconstituted with different EED isoforms exhibit similar substrate preference and specificity. Our work supports the hypothesis that linker histone H1 and chromatin structure are important factors in determining the substrate preference of the EZH2 histone methyltransferase complex.
