Biochemical studies on plant ADP-glucose pyrophosphorylase regulatory properties
Creators: name: Kim, Dongwook
Publisher: name: Washington State University
Year: 2007
Subjects: Starch -- Synthesis -- Regulation

description: ADP-glucose pyrophosphorylase (AGPase) catalyzes the first committed step of
description: starch synthesis in plants. Plant AGPases are composed of two distinct subunits, a
description: catalytic small subunit (SS) and a non-catalytic large subunit (LS). Previously, we have
description: identified and characterized an allosteric LSP52L mutant, which when co-expressed with
description: wild type SS, formed an enzyme with down-regulating allosteric properties. To further
description: investigate the structure-function relationships between the two subunits with regard to
description: allosteric regulation, random chemical mutagenesis was performed to generate SS
description: suppressors of LSP52L. Several putative SS mutant suppressors were identified by their
description: ability to restore glycogen accumulation when co-expressed with LSP52L mutant in
description: Escherichia coli glgC- strain. Kinetic analysis of these second-site mutant SS enzymes
description: indicated that they comprise two distinct classes based on the SS interaction with LSP52L
description: or wild type LS. One class contained bona fide SS suppressors (SSL46F and SSP112L),
description: which reversed the down-regulatory properties of LSP52L but not to wild type LS. The
description: other SS class contained allosteric mutants, SSP308L and SSR350K, which generated upregulated
description: enzymes with wild type LS as well as LSP52L. These results indicate that both LS and SS have a regulatory function in controlling allosteric properties through enhancing subunit interactions. In addition to allosteric regulation, plant AGPases are redox regulated by reduction of an intermolecular disulfide bond (S-S) between two Cys12 residues of catalytic small subunits (SSs). In this study, we replaced the Cys 12 residues with Ala (SSC12A) to remove the disulfide bond in both the potato tuber and Arabidopsis leaf AGPase SSs. SSC12As were co-expressed with the corresponding LSs and resulting enzymes were purified. Kinetic analysis of SSC12A containing enzymes indicated that they have high affinity to the activator 3-phosphoglycerate and substrate ATP in both reducing and oxidizing conditions. Thermal stability of these enzymes was also investigated using both kinetics and biochemical approaches. SSC12A containing
description: enzymes were less stable than the wild type enzymes at high temperatures, based on the
description: results from circular dichroism spectroscopy and enzyme activity. Our results suggested
description: the S-S bond in the AGPase is important for not only enhancing enzyme activation

Corporate newspapers, global warming, and the editorial vigor hypothesis
Creators: name: Kim, Taehyun
Publisher: name: Washington State University
Year: 2007
Subjects: Global warming -- In mass media

description: The purpose of this dissertation was to examine the impact of corporate structure on editorial-page coverage of global warming. Employing a macro-social perspective, this dissertation posits that, contrary to the corporate media critics’ claim of pro-industry bias, newspapers become more critical of dominant economic and political elites as they acquire the characteristics of the corporate form of organization. A national probability survey of daily newspapers in the United States was employed to test following hypotheses:
description: H1: The more a newspaper exhibits the characteristics of the corporate form of organization, the more editorials it will publish about global warming and the Bush administration’s policies toward global warming.
description: H2: The more a newspaper exhibits the characteristics of the corporate form of organization, the more critical its editorials will be of the Bush administration’s policies toward global warming.
description: Survey data supported both hypotheses. Corporate structure was positively related to the number of editorial. Also, corporate structure was positively related to the editorial vigor. Regression analysis was conducted to determine whether the corporate structure would still remain predictors of editorial vigor when controlling for newspaper’s political ideology and ownership type (public vs. private). The findings suggest that 1) structural complexity has direct effects on editorial vigor; 2) newspaper ideology mediates effects of public ownership on editorial vigor, and 3) newspaper ideology is directly related to editorial vigor.

description: Viscosity driven bar mode secular instabilities of rapidly rotating neutron stars are studied using LORENE/Nrotstar code. These instabilities set a more rigorous limit to the rotation frequency of neutron star than the Kepler frequency/mass shedding limit. The procedure employed in the code comprises of perturbing an axisymmetric and stationary configuration of a neutron star and studying its evolution by constructing a series of triaxial quasi-equilibrium configurations. Symmetry breaking point was found out for Polytropic as well as 10 realistic Equations of states (EOS) from the CompOSE database. The concept of piecewise polytropic EOSs has been used to comprehend the rotational instability of Realistic EOSs and validated with 19 different Realistic EOSs from CompOSE. The possibility of detecting quasi-periodic gravitational waves from viscosity driven instability with ground based LIGO/VIRGO interferometers is also discussed very briefly.

description: The existing bounds from CDF on the masses of the fourth generation quarks, t' and b', are reexamined. The bound of 256 GeV on the t' mass assumes that the primary decay of the t' is into q+W, which is not the case for a substantial region of parameter space. The bound of 268 GeV on the b' mass assumes that the branching ratio for b' --> b+Z is very large, which is not only not true for much of parameter space, but is {\em never} true for b' masses above 255 GeV. In addition, it is assumed that the heavy quarks decay within the silicon vertex detector, and for small mixing angles this will not be the case. The experimental bounds, including all of these effects, are found as a function of the other heavy quark mass and the mixing angle.

description: We demonstrate that a key elastic parameter of a suspended crystalline membrane---the Poisson ratio (PR) $ν$---is a non-trivial function of the applied stress $σ$ and of the system size $L$, i.e., $ν=ν_L(σ)$. We consider a generic 2D membrane embedded into space of dimensionality $2+d_c$. (The physical situation corresponds to $d_c=1$.) A particularly important application of our results is free-standing graphene. We find that at very low stress, where the membrane exhibits a linear response, the PR $ν_L(0)$ decreases with increasing $L$ and saturates for $ L\to \infty$ at a value which depends on the boundary conditions and is essentially different from the value $ν=-1/3$ previously predicted by the membrane theory within a self-consisted scaling analysis. By increasing $σ$, one drives a membrane into a non-linear regime characterized by a universal value of PR that depends solely on $d_c.$ This universal non-linear PR acquires its minimum value $ν_{\rm min}=-1$ in the limit $d_c\to \infty.$ With the further increase of $σ$, the PR changes sign and finally saturates at a positive non-universal value prescribed by the conventional elasticity theory. We also show that one should distinguish between the absolute and differential PR ($ν$ and $ν^{\rm diff}$, respectively). While coinciding in the limits of very low and very high stresses, they differ in general, $ν\neq ν^{\rm diff}$. In particular, in the non-linear universal regime, $ν^{\rm diff}$ takes a universal value which, similarly to absolute PR, is a function solely of $d_c$ but is different from the universal value of $ν$. In the limit $d_c\to \infty$, the universal value of $ν^{\rm diff}$ tends to $-1/3$, at variance with the limiting value $-1$ of $ν$. Finally, we briefly discuss generalization of these results to a disordered membrane.

Then we establish conditions on the operators and/or on the underlying Riesz spaces/Banach lattices so that the extensions are order continuous on the product of the whole biduals. We also prove that all Arens extensions of any regular multilinear operator are order continuous in at least one variable and we study when Arens extensions of regular homogeneous polynomials on a Banach lattice $E$ are order continuous on $E^{\sim\sim}$.

description: Ship traffic in the Canadian Arctic nearly tripled between 1990 and 2015. Most of that increase happened in Nunavut waters. Between 1990 and 2015 Cambridge Bay had the third highest increase in vessel traffic in Nunavut. This increase can be explained by the increasing number of vessels transiting the Northwest Passage, including passenger ships, pleasure craft, tankers, and general cargo ships. The Government of Canada is developing a network of low-impact marine transportation corridors in the Arctic that encourages marine transportation traffic to use routes that pose less risk and minimize the impact on communities and the environment. The Low Impact Shipping Corridors will be a framework to guide future federal investments to support marine navigation safety in the North, including improved charting and increased hydrography, in partnership with Northerners. The corridors initiative is co-led by Transport Canada, the Canadian Coast Guard, and Canadian Hydrographic Service. Key considerations in the current prioritization of the corridors include identification of Inuit and northerners’ perspectives on 1) the potential impact of marine vessels on marine areas used for cultural and livelihood activities, and on community members; and 2) potential management strategies for the corridors. This report reflects opinions gathered through participatory mapping and focus group discussions with Cambridge Bay community members who were identified by the Ekaluktutiak Hunters and Trappers Organization as key knowledge holders. Analysis was aimed at understanding Inuit and northerners’ perspectives on the potential impact of marine transportation on local marine use areas and community members, and on identification of potential management strategies for the low impact shipping corridors. This report was validated by the research participants.

Interactions Among Techniques Addressing Quality Attributes

Publisher: name: Carnegie Mellon University
Year: 2003
Subjects: subject: 80309 Software Engineering
subject: FOS: Computer and information sciences

description: There is very little published work on how techniques that promote different architectural qualities interact with each other. When developing a software system, software architects need to understand the relationships among these techniques. For example, if a system is compromised, architects must consider questions such as whether it makes sense to apply damage confinement to achieve dependability, while at the same time shutting down components to promote security. To help answer such questions, this report provides matrices in which various techniques for promoting different architectural qualities are analyzed relative to each other. Four architectural qualities were analyzed: performance, security, modifiability, and dependability. The techniques that promote each one were selected and categorized as promotion, detection, or correction. For each category, matrices are presented that provide a detailed description of why a particular interaction is positive, negative, or neutral, or cannot be determined without assessing a concrete system.
Application of ultra high hydrostatic pressure for investigating the binding of flavor compounds to β-lactoglobulin via headspace solid phase microextraction-gas chromatography
Creators: name: Hoang, Tinyee Arden
Publisher: name: Washington State University
Year: 2006
Subjects: Flavor -- Analysis

description: Fluorescence spectroscopy and headspace-solid phase microextraction (HS-SPME) gas chromatography analysis were used to evaluate the effects of ultra high hydrostatic pressure (UHP) (600 MPa) and pH (3.0-9.0) on β-lactoglobulin (BLG) surface hydrophobicity and binding of selected flavor compounds. An increase in tryptophan intrinsic fluorescence intensity of BLG was observed after UHP of 16 min, which suggested that the tryptophan residues were exposed during the unfolding of BLG. A 2 nm red-shift in tryptophan emission wavelength was observed after UHP come-up time, indicating changes in the polarity of tryptophan residues from a less polar to a more polar microenvironment. After UHP treatment come-up time of BLG at pH 9.0, there was an increase in BLG surface hydrophobicity, suggesting a flexible molecular structure due to surface denaturation of BLG at alkaline pH. UHP treatment of BLG solutions at pH 3.0, 5.0, and 9.0 resulted in decreases in the number of binding sites for the nonpolar fluorescence probe 6-propionyl-2-(dimethylamino)-naphthalene (PRODAN). UHP treatment did not show significant influences in the apparent dissociation constant of PRODAN. An extraction time of 10 min was used for HS-SPME of δ-decalactone, 2-methylbutyraldehyde, ethyl lactate, and diacetyl. Although the CAR/PDMS fiber was able to detect diacetyl, ethyl lactate, and 2-methylbutyraldehyde, the PDMS/DVB SPME fiber was selected for the extraction of selected flavor compounds due to reproducible and linear (RP2P > 0.954) calibration plots, and its semi-polar nature to extract δ-decalactone. As observed by fluorescence quenching, there is no linear relationship between UHP treatment of BLG at 600 MPa and the number of binding sites for diacetyl, 2-methylbutyraldehyde, δ-decalactone, and ethyl lactate. BLG has low binding affinity for the selected flavor compounds with polar groups, and UHP treatment of BLG did not influence binding of 2-methylbutyraldehyde as observed by fluorescence quenching experiments. Headspace analysis of UHP–treated BLG resulted in significant increases (p < 0.05) in flavor retention over native BLG. In addition, a short UHP treatment time (come-up time) may be adequate for flavor retention.

description: We consider systems of weakly interacting fermions on a lattice. The corresponding free fermionic system is assumed to have a ground state separated by a gap from the rest of the spectrum. We prove that, if both the interaction and the free Hamiltonian are sums of sufficiently rapidly decaying terms, and if the interaction is sufficiently weak, then the interacting system has a spectral gap as well, uniformly in the lattice size. Our approach relies on convergent fermionic perturbation theory, thus providing an alternative method to the one used recently in [MB Hastings. arXiv:1706.02270], and extending the result to include non-selfadjoint interaction terms.

description: We examine Fogel’s influential hypothesis that new transportation technologies may be dispensable if pre-existing technologies are viable or can simply be improved. Exploiting the construction of colonial railroads in Nigeria, we find that the railway has large long-lasting impacts on individual and local development in the North, but virtually no impact in the South neither in the short run nor in the long run. This heterogeneous impact of the railway can be accounted for by the level of pre-railway access to ports of export. Consistent with Fogel’s argument, the railway did not transform areas that had viable transportation alternatives for exporting purposes. Using information on changes in shipping costs and quantities, we highlight the importance of opportunity costs to the adoption and impact of new transportation investments.

description: Small manufacturing enterprises face a number of challenges when integrating computer-aided design (CAD) tools and computer-aided engineering (CAE) tools into their design processes. One of the most significant challenges is interoperability across the wide range of commercial CAD and CAE tools. Although many of these tools support industry data standards and claim to be interoperable, the connection between them is not seamless. This report summarizes two case studies of tool integration activities at one small manufacturer. The first study examines the enhancement of the product development process resulting from replacement of a two-dimensional CAD system with a three-dimensional CAD system. The second examines the creation of an in-house capability to perform finite element analysis (FEA), replacing analysis that had previously been outsourced. As a result of these experiences, the manufacturer learned that improved productivity and superior designs could be obtained by integrating analysis into the design process at the earlier stages of conceptual and preliminary design. The manufacturer also learned that the design process and some design techniques had to change for the company to use the CAD and FEA tools effectively.

description: We have performed 2D hybrid simulations of non-relativistic collisionless shocks in the presence of pre-existing energetic particles ("seeds"); such a study applies, for instance, to the re-acceleration of Galactic cosmic rays (CRs) in supernova remnant (SNR) shocks and solar wind energetic particles in heliospheric shocks. Energetic particles can be effectively reflected and accelerated regardless of shock inclination via a process that we call \emph{diffusive shock re-acceleration}. We find that reaccelerated seeds can drive the streaming instability in the shock upstream and produce effective magnetic field amplification. This can eventually trigger the injection of thermal protons even at oblique shocks that ordinarily cannot inject thermal particles. We characterize the current in reflected seeds, finding that it tends to a universal value $J\simeq e n_{cr} v_{sh}$, where $e n_{cr}$ is the seed charge density and $v_{sh}$ is the shock velocity. When applying our results to SNRs, we find that the re-acceleration of Galactic CRs can excite the Bell instability to non-linear levels in less than $\sim 10$ yr, thereby providing a minimum level of magnetic field amplification for any SNR shock. Finally, we discuss the relevance of diffusive shock re-acceleration also for other environments, such as heliospheric shocks, Galactic superbubbles, and clusters of galaxies.

Quality of life

description: Background: Promoting quality of life (QoL) is a key priority in cancer care. We investigated the hypothesis that, in comparison to usual care, exercise post-neoadjuvant chemoradiation therapy/prior to surgical resection will reduce pain, fatigue, and insomnia, and will improve physical and mental health perceptions in patients with locally advanced stage rectal cancer. Methods: In this non-randomized controlled pilot trial, patients in the supervised exercise group (EG; M age = 64 years; 64% male) and in the control group (CG; M age = 72 years; 69% male) completed the European Organization for Research and Treatment of Cancer core Quality of Life questionnaire and the RAND 36-Item Health Survey three times: pre-neoadjuvant chemoradiation therapy (Time 1; n EC = 24; n CG = 11), post-neoadjuvant chemoradiation therapy/pre-exercise intervention (Time 2; n EC = 23; n CG = 10), and post-exercise intervention (Time 3; n EC = 22; n CG = 10). The 6-week exercise intervention was delivered in hospital and comprised of interval aerobic training. Patients trained in pairs three times per week for 30 to 40 min. Data were analyzed by Mann–Whitney tests and by Wilcoxon matched-pairs signed-rank tests. Results: No significant between-group differences in changes were found for any of the outcomes. In both groups, fatigue levels decreased and physical health perceptions increased from pre- to post-exercise intervention. Pain levels also decreased from pre- to post-exercise intervention, albeit not significantly. Conclusions: The findings from this study can be used to guide a more definitive trial as they provide preliminary evidence regarding the potential effects of pre-operative exercise on self-reported pain, fatigue, insomnia, and health perceptions in patients with locally advanced rectal cancer. Trial registration: This study has been registered with clinicaltrials.gov (NCT01325909; March 29, 2011).

description: Mustard seed meal from Brassica carinata has shown both nematicidal as well as insect oviposition deterring properties against the root knot nematode Meloidogyne chitwoodi, and the Colorado Potato Beetle (CPB), Leptinotarsa decemlineata, respectively. In addition, entomopathogenic nematodes (EPN) have shown biocontrol potential against both CPB and M. chitwoodi. The objectives of this research were to 1) determine whether entomopathogenic nematodes can reduce M. chitwoodi populations, 2) determine whether entomopathogenic nematodes can infect CPB larvae, 3) determine whether mustard seed meal can decrease M. chitwoodi populations, 4) determine whether the two methods (mustard seed meal and EPN) can be used simultaneously against both the CPB and M. chitwoodi, and 5) determine if the addition of mustard seed meal amendment deters CPB oviposition. Field and greenhouse trials were conducted in WSU Prosser, WA and WSU Pullman, WA in 2006 and 2007. Mustard seed meal alone, EPN, and combination of mustard seed meal and EPN significantly reduced the percent culled potato tubers, percent infection, and infection index due to M. chitwoodi in field trials. In the greenhouse trials, mustard seed meal, S. feltiae and S. riobrave, and treatment combinations of mustard seed meal with species of EPN reduced M. chitwoodi infection significantly. Both species of EPN were able to infect CPB larvae in the field and greenhouse, regardless of mustard seed meal amendment. The oviposition rates of CPB in the field were reduced significantly on mustard seed meal amended plants compared to the untreated control. In the greenhouse there were no effects of mustard seed meal amendment on CPB plant choice. EPN and mustard seed meal have shown promising potential as biological control methods to control both the above ground herbivorous insect pest, CPB, and the below ground nematode pest of potato tubers, M. chitwoodi. This multifaceted approach will provide potato growers with new options for sustainable control of both the root knot nematode and the insect pest.

description: We perform the stability analysis of Schwarzschild-AdS (SAdS) black hole in the Einstein-Ricci cubic gravity. It shows that the Ricci tensor perturbations exhibit unstable modes for small black holes. We call this the mass-induced instability of SAdS black hole because the instability of small black holes arises from the massiveness in the linearized Einstein-Ricci cubic gravity, but not a feature of higher-order derivative theory giving ghost states. Also, we point out that the correlated stability conjecture holds for the SAdS black hole by computing the Wald entropy of SAdS black hole in Einstein-Ricci cubic gravity.

description: We use Atacama Large Millimeter/submillimeter Array CO(2-1) observations of six low-redshift Palomar-Green quasars to study the distribution and kinematics of the molecular gas of their host galaxies at kpc-scale resolution. While the molecular gas content, molecular gas fraction, and star formation rates are similar to those of nearby massive, star-forming galaxies, the quasar host galaxies possess exceptionally compact, disky molecular gas distributions with a median half-light radius of 1.8 kpc and molecular gas mass surface densities $\gtrsim 22$ $M_\odot$pc$^{-2}$. While the overall velocity field of the molecular gas is dominated by regular rotation out to large radii, with rotation velocity-to-velocity dispersion ratio $\gtrsim 9$, the nuclear region displays substantial kinematic complexity associated with small-scale substructure in the gas distribution. A tilted-ring analysis reveals that the kinematic and photometric position angles are misaligned on average by $\sim 34 \pm 26^\circ$, and provides evidence of kinematic twisting. These observations provide tantalizing clues to the detailed physical conditions of the circumnuclear environments of actively accreting supermassive black holes.

description: Статья посвящена описанию комплекса магических элементов в даосском ритуале, который состоит из устных заклинаний, амулетов, шагов Юя и мудр, а также истории происхождения этих практик, их структуре и основным составным частям. В работе делается вывод о том, что все четыре вышеназванные составляющие даосской литургии не могут и не должны рассматриваться по отдельности. Они мыслятся как часть неделимого целого, апеллирующего к высшим силам совместно, но не имеют самоценности даже в случае постулируемой изобразительности любой из них.
description: The article describes magic aspects in Taoist rituals, i.e. incantations, talismans, Mudras and Yu paces. It focuses on the origins of esoteric traditions, their structure and main constituents. It is concluded that all the four aforementioned components of Taoist ritual cannot and should not be studied separately but are parts of one entity. They jointly appeal to the divine powers but have no self-value even in case of a postulated figurative quality of any given component

description: This letter presents the first ab initio, fully electromagnetic, kinetic simulations of magnetized turbulence in a homogeneous, weakly collisional plasma at the scale of the ion Larmor radius (ion gyroscale). Magnetic and electric-field energy spectra show a break at the ion gyroscale; the spectral slopes are consistent with scaling predictions for critically balanced turbulence of Alfven waves above the ion gyroscale (spectral index -5/3) and of kinetic Alfven waves below the ion gyroscale (spectral indices of -7/3 for magnetic and -1/3 for electric fluctuations). This behavior is also qualitatively consistent with in situ measurements of turbulence in the solar wind. Our findings support the hypothesis that the frequencies of turbulent fluctuations in the solar wind remain well below the ion cyclotron frequency both above and below the ion gyroscale.

description: Under the serious concerns of environmental degradation due to the greenhouse gas emissions of ordinary Portland cement (OPC) industry, geopolymer concretes have been qualified as a good alternative to OPC concretes. Geopolymer concretes, known by their good mechanical and durability properties, possess different fresh and hardened behaviours as compared to OPC concretes. This reason is one of the main obstacles that hinder the deployment of these concretes worldwide. Furthermore, geopolymer concretes developed in the literature are mostly based on fly ash while only few works were carried out on geopolymer concrete based on a blended mix of metakaolin (MK)/granulated blast furnace slag (GBFS). In this context, this paper aims to compare the fresh and hardened properties of geopolymer concrete based on MK and GBFS as well as OPC self-compacting concrete (OPSCC) with the same volume of binder. At fresh state, the workability evolution during the first hour after mixing was followed. At hardened state, mechanical strengths, dynamic modulus of elasticity, water porosity and shrinkage are investigated with a special attention to the early age behaviour.
