The effect of process conditions on productivity and glycosylation of cystatin C in P. pastoris and DNA microarray analysis of amino acid limitations in S. cerevisiae culture
Creators: name: Pritchett, Jason
Publisher: name: University of British Columbia
Year: 2009

description: Human cystatin C is a cysteine-proteinase inhibitor with several potential therapeutic applications. A recombinant variant of cystatin C with two potential sites for N-linked glycosylation (Nakamura, Ogawa et al. 2000) was selected for expression in the yeast Pichia pastoris. Glycosylation has been shown to significantly improve the heat stability and activity of recombinant cystatin C (Nakamura, Ogawa et al. 1998). When using standard fermentation protocols however, most cystatin C is not glycosylated. Thus, the effects of induction pH, temperature, and nitrogen sources on cystatin C productivity and glycosylation were examined in 250 mL shake flasks and 2-litre bioreactors. The pH and temperature were studied over the ranges of 5.2 - 6.8, and 21 - 35°C respectively. Nitrogen sources examined include ammonium hydroxide, peptone and amino acid supplements. Nitrogen source was the most significant parameter. The maximum cystatin C productivity and glycosylation was obtained under conditions of 20 g•L⁻¹ peptone, 20 g•L⁻¹ amino acid mix, and 0 g•L⁻¹ ammonium hydroxide resulting in 13.6 nmol-gDCW⁻¹•h⁻¹ cystatin C with 30% glycosylated species, a five-fold increase from standard fermentation conditions. In a separate study using S. cerevisiae, DNA microarray analysis was used to monitor gene expression changes resulting from amino acid limitations in fermentation media. Experiments were performed to examine leucine and glutamine limitations imposed on batch cultures. Recent literature results from Gasch (Gasch, Spellman et al. 2000) and Natarajan (Natarajan, Meyer et al. 2001) were also re-analyzed. The results show that both leucine and glutamine biosynthesis genes were differentially expressed as much as 13-fold under complete amino acid starvation and genes involved in leucine and histidine biosynthesis were significantly up-regulated under mild leucine limitation and histidine starvation with 3AT (3-aminotriazol). Additional amino acid starvation experiments revealed that leucine starvation resulted in a 2-fold up-regulation of the leucine biosynthesis genes LEU1, LEU2 and LEU4. However, changes in gene expression for glutamate biosynthesis genes under glutamic acid starvation resulted in no distinguishable trends.

Particle abundance in a thermal plasma: quantum kinetics vs. Boltzmann equation

description: We study the abundance of a particle species in a thermalized plasma by introducing a quantum kinetic description based on the non-equilibrium effective action. A stochastic interpretation of quantum kinetics in terms of a Langevin equation emerges naturally. We consider a particle species that is stable in the vacuum and interacts with \emph{heavier} particles that constitute a thermal bath in equilibrium and define of a fully renormalized single particle distribution function. The distribution function thermalizes on a time scale determined by the \emph{quasiparticle} relaxation rate. The equilibrium distribution function depends on the full spectral density and features off-shell contributions to the particle abundance. A model of a bosonic field $Φ$ in interaction with two \emph{heavier} bosonic fields is studied. We find substantial departures from the Bose-Einstein result both in the high temperature and the low temperature but high momentum region. In the latter the abundance is exponentially suppressed but larger than the Bose-Einstein result. We obtain the Boltzmann equation in renormalized perturbation theory and highlight the origin of the differences. We argue that the corrections to the abundance of cold dark matter candidates are observationally negligible and that recombination erases any possible spectral distortions of the CMB. However we expect that the enhancement at high temperature may be important for baryogenesis.

Community/Rural/Urban Development

description: Rural communities across the United States have been undergoing dramatic economic restructuring. As a result, many rural communities are struggling to recover from the closure or downsizing of manufacturing facilities and to implement economic development programs. The goal of this study was to gain new insights into community, organizational, and economic factors that underlie effective rural community response to economic distress. The study covers communities with populations between 500 and 10,000 in the states of Illinois, Iowa, Minnesota, Missouri, North Dakota, and South Dakota. Data come from a survey of local government officials of all towns in the six states with populations between 500 and 10,000. Surveys were mailed to 2,118 towns during the summer of 1993, of which 1,396 useable questionnaires were returned, for an overall response rate of almost 66 percent. Among the towns that responded, 16.3 percent reported closures or downsizing affecting 25 workers or more during the 1989 to 1992 period Retail stores were the business type that were most often reported as being closed, followed by manufacturers. The number of jobs lost per establishment was greatest in the manufacturing sector. When the community representatives were asked about the effect of the plant closing(s) on displaced workers, their responses indicated that about 38 percent of the displaced workers either remained unemployed or underemployed (11%), took lower paying jobs (14.5%), or retired early (13%). Further, about 24 percent of the workers were forced to leave the community to find work. Only 31 percent of the workers reportedly stayed in the community and obtained comparable replacement jobs. Of the towns with closures or downsizing, 46 percent evaluated the overall impacts on the community as "serious" or "severe", while 48 percent of the communities reported "serious' or "severe" economic effects. The communities utilized a wide variety of economic development strategies to adapt to business downturns and to foster business and economic growth. A major objective of the next phase of this research will be to investigate the degree to which various communities have been able to overcome their economic problems and establish stable or growing economies whereas others have had less success in sustaining their economies at pre-closure levels.

description: North Dakota's recreational fishing industry is an important part of the state's economic base. Resident and nonresident anglers spent nearly $260 million dollars on fishing-related activities in the state in 1990 (Baltezore and Leitch 1992). Management of a resource that generates this amount of economic activity requires accurate and periodic information. Management uses information in at least two ways. Information is initially used to make a decision. Once a decision is made, additional information is collected to assess the results or outcomes of that decision. In effect, information is used to make a decision and monitor changes resulting from that decision (Kerestes and Leitch 1983). Periodic information is needed to monitor the outcomes of management's decision.

description: This paper studies what causes (small-scale) farmers to leave their farms and typically move to urban areas. A data set is constructed by linking survey results with financial data, and the data set is analyzed by multivariate statistical techniques. Our results indicate that, while existence and size of future farm production is important, there is also a difference between farmers who primarily have financial objectives for their farming, and those who have more lifestyle oriented objectives. The latter group is, everything else being equal, more likely to stay on the farm. This could imply that, if preventing migration from rural to urban areas is a policy objective, production support schemes will be effective for some groups, but will be less effective for the group with lifestyle objectives. If this group is to be encouraged to stay on the countryside, policies directed at improving the general living conditions in the local community are likely to be more effective than specific support schemes related to agricultural production.

description: We study the reaction $e^+e^-\toπ^0γ$ based on a dispersive representation of the underlying $π^0\toγγ^*$ transition form factor. As a first application, we evaluate the contribution of the $π^0γ$ channel to the hadronic-vacuum-polarization correction to the anomalous magnetic moment of the muon. We find $a_μ^{π^0γ}\big|_{\leq 1.35\,\text{GeV}}=43.8(6)\times 10^{-11}$, in line with evaluations from the direct integration of the data. Second, our fit determines the resonance parameters of $ω$ and $ϕ$. We observe good agreement with the $e^+e^-\to3π$ channel, explaining a previous tension in the $ω$ mass between $π^0γ$ and $3π$ by an unphysical phase in the fit function. Combining both channels we find $\bar M_ω=782.736(24)\,\text{MeV}$ and $\bar M_ϕ=1019.457(20)\,\text{MeV}$ for the masses including vacuum-polarization corrections. The $ϕ$ mass agrees perfectly with the PDG average, which is dominated by determinations from the $\bar K K$ channel, demonstrating consistency with $3π$ and $π^0γ$. For the $ω$ mass, our result is consistent but more precise, exacerbating tensions with the $ω$ mass extracted via isospin-breaking effects from the $2π$ channel.

Quantum field theory from a quantum cellular automaton in one spatial dimension and a no-go theorem in higher dimensions

description: It has been shown that certain quantum walks give rise to relativistic wave equations, such as the Dirac and Weyl equations, in their long-wavelength limits. This intriguing result raises the question of whether something similar can happen in the multi-particle case. We construct a one-dimensional quantum cellular automaton (QCA) model which matches the quantum walk in the single particle case, and which approaches the quantum field theory of free fermions in the long-wavelength limit. However, we show that this class of constructions does not generalize to higher spatial dimensions in any straightforward way, and that no construction with similar properties is possible in two or more spatial dimensions. This rules out the most common approaches based on QCAs. We suggest possible methods to overcome this barrier while retaining locality.

Infrared instability from nonlinear QCD evolution

Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Using the Balitsky-Kovchegov (BK) equation as an explicit example, we show that nonlinear QCD evolution leads to an instability in the propagation toward the infrared of the gluon transverse momentum distribution, if one starts with a state with an infrared cut-off. This effect takes the mathematical form of rapidly moving traveling wave solutions of the BK equation, which we investigate by numerical simulations. These traveling wave solutions are different from those governing the transition to saturation, which propagate towards the ultraviolet. The infrared wave speed, formally infinite for the leading order QCD kernel, is determined by higher order corrections. This mechanism could play a role in the rapid decrease of the mean free path in the Color Glass Condensate scenario for heavy ion collisions.

description: AIMS. We calculate the stellar density using star counts obtained from Gaia DR2 up to a Galactocentric distance R=20 kpc with a deconvolution technique for the parallax errors. Then we analyse the density in order to study the structure of the outer Galactic disc, mainly the warp. METHODS. In order to carry out the deconvolution, we used the Lucy inversion technique for recovering the corrected star counts. We also used the Gaia luminosity function of stars with $M_G<10$ to extract the stellar density from the star counts. RESULTS. The stellar density maps can be fitted by an exponential disc in the radial direction $h_r=2.07\pm0.07$ kpc, with a weak dependence on the azimuth, extended up to 20 kpc without any cut-off. The flare and warp are clearly visible. The best fit of a symmetrical S-shaped warp gives $z_w= z_\odot+(37\pm 4.2(stat.)-0.91(syst.))$ pc $(R/R_\odot )^{2.42\pm 0.76(stat.) + 0.129 (syst.)} sin(ϕ+9.3\pm 7.37 (stat.) +4.48 (syst.))$ for the whole population. When we analyse the northern and southern warps separately, we obtain an asymmetry of an $\sim25\%$ larger amplitude in the north. This result may be influenced by extinction because the Gaia G band is quite prone to extinction biases. However, we tested the accuracy of the extinction map we used, which shows that the extinction is determined very well in the outer disc. Nevertheless, we recall that we do not know the full extinction error, and neither do we know the systematic error of the map, which may influence the final result. The analysis was also carried out for very luminous stars alone ($M_G

description: In the international comparison the structure of milk production in Austria is small scale. The present study presents two theoretical approaches to explain the persistence of small dairy farms in Austria: the opportunity cost principle and the theory of the agricultural household. With regard to the first one it is debatable whether the flat rates really can represent the costs of own production factors in their alternative uses in small enterprises. An illustration on the basis of production cost accounts shows that small dairy farms with no possibilities for the utilization of their own production factors (especially for labour) can cover the production costs by revenues only. Secondly it is argued that agricultural production is likely to continue in small dairy farms as long as the enterprise contributes persistently to the household income of the family. Indicators from the Farm Accountancy Data Network (FADN) of voluntarily participating farms in Austria support the notion that labour is allocated efficiently between the enterprise and the household in small operations in order to achieve maximum total income. The study proposes arguments according to which it can be expected that rather small dairy farms are going to be a prominent presence in Austrian agriculture also in the future.

description: We calculate the intershell resistance R_{21} in a multiwall carbon nanotube as a function of temperature T and Fermi level (e.g. a gate voltage), varying the chirality of the inner and outer tubes. This is done in a so-called Coulomb drag setup, where a current I_1 in one shell induces a voltage drop V_2 in another shell by the screened Coulomb interaction between the shells neglecting the intershell tunnelling. We provide benchmark results for R_{21}=V_2/I_1 within the Fermi liquid theory using Boltzmann equations. The band structure gives rise to strongly chirality dependent suppression effects for the Coulomb drag between different tubes due to selection rules combined with mismatching of wave vector and crystal angular momentum conservation near the Fermi level. This gives rise to orders of magnitude changes in R_{21} and even the sign of R_{21} can change depending on the chirality of the inner and outer tube and misalignment of inner and outer tube Fermi levels. However for any tube combination, we predict a dip (or peak) in R_{21} as a function of gate voltage, since R_{21} vanishes at the electron-hole symmetry point. As a byproduct, we classified all metallic tubes into either zigzag-like or armchair-like, which have two different non-zero crystal angular momenta m_a, m_b and only zero angular momentum, respectively.

description: The accurate extraction and the reliable, repeatable reduction of graphene - metal contact resistance (R$_{C}$) are still open issues in graphene technology. Here, we demonstrate the importance of following clear protocols when extracting R$_{C}$ using the transfer length method (TLM). We use the example of back-gated graphene TLM structures with nickel contacts, a complementary metal oxide semiconductor compatible metal. The accurate extraction of R$_{C}$ is significantly affected by generally observable Dirac voltage shifts with increasing channel lengths in ambient conditions. R$_{C}$ is generally a function of the carrier density in graphene. Hence, the position of the Fermi level and the gate voltage impact the extraction of R$_{C}$. Measurements in high vacuum, on the other hand, result in dependable extraction of R$_{C}$ as a function of gate voltage owing to minimal spread in Dirac voltages. We further assess the accurate measurement and extraction of important parameters like contact-end resistance, transfer length, sheet resistance of graphene under the metal contact and specific contact resistivity as a function of the back-gate voltage. The presented methodology has also been applied to devices with gold and copper contacts, with similar conclusions.

description: In current economic reality, there seems to be a clear need to recognize, characterize and place small scale agriculture in a setup which accounts for novel trends in the modes of doing business in the global economy and with respect to the changing role of agriculture along development transition. Providing that ground it will make it possible to design and promote appropriate policy strategies that will best accommodate small scale farmers’ needs and exploit their potential for agricultural development. The present paper employs a multi country household survey database developed from ESA-FAO, and a series of ad hoc land thresholds to categorize rural households as small or large scale farmers and identify some of their key characteristics as well as their economic weight in the rural as well as the national economy.

We discuss the outcome of the corresponding interpolations between lattice QCD data and the physical values for these two nucleon observables. It turns out that in order to obtain successful interpolating functions at one-loop order, the inclusion of explicit delta (1232) degrees of freedom is not decisive for the nucleon mass but crucial for g_A. A chiral extrapolation of recent lattice results by the LHP collaborations is also shown.

description: The work in this thesis is motivated by the problem of navigating the content of a collection of related documents, which is cumbersome if only a list of documents is given. Automatically structuring the content organization of a dataset by identifying topically cohesive segments and linking segments describing the same topic addresses this issue. Previous work deals with this problem by using a multi-document joint model for segmentation and topic identification at the dataset level, a perspective we also take. This multi document approach to segmentation contrasts with approaches that segment documents individually. The advantage of a multi-document model is that segmentation is leveraged by repeated descriptions of the same topic across different documents. We continue this line of work by hypothesizing that vocabulary relation ships between different segments can be used to obtain a more accurate segmentation and topic segment identification. We also hypothesize that documents that share the same modality (video transcripts, Power Point, etc.) have similar characteristics that could be modeled to obtain a better performance in these tasks. To study the previous hypothesis, we propose BeamSeg, a joint model for multi-document segmentation and topic identification where it is assumed that segments have vocabulary usage relationships. BeamSeg implements segmentation and topic identification in an unsupervised Bayesian setting by drawing from the samemultinomial language model segments with the same topic. Contrary to previous work, we assume that language models are not independent since the vocabulary changes in consecutive segments are expected to be smooth and not abrupt. We achieve this by putting a dynamic Dirichlet prior over the language mod els that takes into account data contributions from other topics. Additionally, we encode in BeamSeg that documents with different modalities have similar segment length characteristics, and, thus, each modality has its segment length prior. To better understand the performance advantages of the proposed joint model approach, we compare BeamSeg to a pipeline approach (performing segmentation and topic identification sequentially). In this context, we extend two single-document models to the multi-document case and pro pose a graph-community detection approach to topic identification. In order to test our hypothesis, we carry out a data collection task, as datasets from previous works have few documents with short segments, leav ing little room to observe vocabulary relationships. The evaluation using the collected dataset shows that BeamSeg obtains the best results affording this way practical improvements in both segmentation and topic identification and corroborating our hypothesis.

description: Pairwise conversions of neutrinos have complicated the challenging goal of quantifying the relevance of neutrino microphysics in compact astrophysical objects, limiting the ability to perform numerical simulations and encouraging the employment of semi-analytical tools, such as the linear stability analysis. Given the high neutrino density, the dependence of pairwise conversions on the neutrino energy has been deemed to play a negligible role. We show that fast pairwise conversions are affected by the neutrino energy, especially in the non-linear regime. An earlier onset of flavor conversions and a higher oscillation frequency are found as the vacuum frequency increases (i.e., the neutrino energy decreases); the oscillation periodicity, otherwise present, is gradually destroyed as the vacuum frequency increases. Such effects are, however, not further exacerbated by the inclusion of spectral energy distributions for neutrinos, contrary to what was found for "slow" neutrino-neutrino conversions. In addition, our findings highlight the dependence of fast pairwise conversions on the neutrino mass ordering for realistic values of the neutrino vacuum frequency. Our findings highlight the limitations intrinsic to widely adopted approximations and extrapolations based on the linear regime of fast conversions. In order to gauge their possible impact on the source physics, a more sophisticated modeling of pairwise conversions is necessary.

description: The stability and dynamics of nonlinear Schrodinger superflows past a two-dimensional disk are investigated using a specially adapted pseudo-spectral method based on mapped Chebychev polynomials. This efficient numerical method allows the imposition of both Dirichlet and Neumann boundary conditions at the disk border. Small coherence length boundary-layer approximations to stationary solutions are obtained analytically. Newton branch-following is used to compute the complete bifurcation diagram of stationary solutions. The dependence of the critical Mach number on the coherence length is characterized. Above the critical Mach number, at coherence length larger than fifteen times the diameter of the disk, rarefaction pulses are dynamically nucleated, replacing the vortices that are nucleated at small coherence length.

description: The equation of state of a homogeneous two-dimensional Bose gas is calculated using quantum Monte Carlo methods. The low-density universal behavior is investigated using different interatomic model potentials, both finite-ranged and strictly repulsive and zero-ranged supporting a bound state. The condensate fraction and the pair distribution function are calculated as a function of the gas parameter, ranging from the dilute to the strongly correlated regime. In the case of the zero-range pseudopotential we discuss the stability of the gas-like state for large values of the two-dimensional scattering length, and we calculate the critical density where the system becomes unstable against cluster formation.

Small Farms in the EU: How Small is Small?

description: This paper discusses and explores different approaches to the definition of small in relation to farms in the EU. It focuses on distributions of farms using different size criteria, making comparisons of the extent to which one criterion maps onto another. Differences in farm structure that exist between and within both the established and new Member States make it particularly difficult to determine a unique definition of smallness, suggesting perhaps the use of a relative rather than absolute measure of size.

description: In the present research, an artificial neural network model was developed to predict the pool boiling heat transfer coefficient (HTC) of refrigerant-based nanofluids based on a large number of experimental data (1342) extracted from the literature. Diverse training algorithms, e.g., Bayesian regulation backpropagation, Levenberg–Marquardt (LM), Resilient backpropagation and scaled conjugate gradient were utilized. Besides, several transfer functions like log-sigmoid (logsig), radial basis (radbas), soft max transfer function (softmax), hard-limit (hardlim), tan-sigmoid (tansig) and triangular basis (tribas) were applied for the hidden layer, and their influences on model correctness were surveyed. The effects of heat flux, saturation pressure, nanoparticle thermal conductivity, base fluid thermal conductivity, nanoparticle concentration (mass%), nanoparticles size and lubricant concentration (mass%) on the pool boiling HTC of refrigerant-based nanofluids were determined over wide ranges of operating conditions. A network possessing one hidden layer with 19 neurons using tansig and purelin as transfer functions in hidden and output layers in a row was introduced as a model having the best performance. In addition, LM was known as a much more efficient train algorithm in comparison with others resulting in extremely precise prediction. The outcomes indicated the present model could accurately estimate the pool boiling HTC of refrigerant-based nanofluids with a correlation coefficient (R2) of 0.9948 and overall mean square error of 0.01529.

description: Face mask use by the general public for limiting the spread of the COVID-19 pandemic is controversial, though increasingly recommended, and the potential of this intervention is not well understood. We develop a compartmental model for assessing the community-wide impact of mask use by the general, asymptomatic public, a portion of which may be asymptomatically infectious. Model simulations, using data relevant to COVID-19 dynamics in the US states of New York and Washington, suggest that broad adoption of even relatively ineffective face masks may meaningfully reduce community transmission of COVID-19 and decrease peak hospitalizations and deaths. Moreover, mask use decreases the effective transmission rate in nearly linear proportion to the product of mask effectiveness (as a fraction of potentially infectious contacts blocked) and coverage rate (as a fraction of the general population), while the impact on epidemiologic outcomes (death, hospitalizations) is highly nonlinear, indicating masks could synergize with other non-pharmaceutical measures. Masks are found to be useful with respect to both preventing illness in healthy persons and preventing asymptomatic transmission. Hypothetical mask adoption scenarios suggest that immediate near universal (80%) adoption of moderately (50%) effective masks could prevent on the order of 17--45% of projected deaths over two months in New York, while decreasing the peak daily death rate by 34--58%, absent other changes in epidemic dynamics. Our results suggest use of face masks by the general public is potentially of high value in curtailing community transmission and the burden of the pandemic. The community-wide benefits are likely to be greatest when face masks are used in conjunction with other non-pharmaceutical practices (such as social-distancing), and when adoption is nearly universal (nation-wide) and compliance is high.

description: This paper explains regionally differentiated patterns of structural change based on a theoretical framework dealing with strategic interaction of farms on the land market. The main research question focuses on the causes of regionally persistent structures. An empirical Markov chain model is defined for the West German agricultural sector. Thereby it is possible to explain the probabilities of farm growth, decline or exit in terms of the current and former regional farm size structure. Further, the impact of variables describing the regional farm structure, thereby indicating market power of the large, the potential of high competition for land within a region and possibly high rents of the status quo in combination with sunk costs, is quantified. The results confirm the relevance of strategic interaction as a crucial determinant of regionally different structural change and persistent regional differences in the farm size structure over time.
