description: We study the generation of cosmological perturbations during the Hagedorn phase of string gas cosmology. Using tools of string thermodynamics we provide indications that it may be possible to obtain a nearly scale-invariant spectrum of cosmological fluctuations on scales which are of cosmological interest today. In our cosmological scenario, the early Hagedorn phase of string gas cosmology goes over smoothly into the radiation-dominated phase of standard cosmology, without having a period of cosmological inflation.

description: This paper analyses the organisation of the post-harvest Nile perch supply chain centred on Lake Victoria in East Africa to test the practical relevance of the market-driven supply chain thesis proposed by Folkerts and Koehorst (1998). It finds that while international consumer demand, particularly in demanding improved quality standards according to HACCP principles, is having profound local organisational ramifications, the evolving supply chain is presently best characterised as being a hybrid one - neither exclusively production, nor marketdriven.

description: This article reports the results of an industry-level study that seeks to identify empirical regularities between firm strategy, management style, organisational structure and performance in the Spanish fresh fruit and vegetable (fresh produce) industry using strategic group analysis. Groups were formed from key dimensions reflecting firms' strategic orientations. Performance levels did not differ systematically between strategic groups, but performance was found to be influenced by the alignment between entrepreneurial culture and organisational structure. A move towards greater flexibility and/or adopting an entrepreneurial style are both likely to contribute to an improvement in the overall performance of the firm.

description: Theoretical and experimental studies of the interaction between spins and temperature are vital for the development of spin caloritronics, as they dictate the design of future devices. In this work, we propose a two-terminal cold-atom simulator to study that interaction. The proposed quantum simulator consists of strongly interacting atoms that occupy two temperature reservoirs connected by a one-dimensional link. First, we argue that the dynamics in the link can be described using an inhomogeneous Heisenberg spin chain whose couplings are defined by the local temperature. Second, we show the existence of a spin current in a system with a temperature difference by studying the dynamics that follows the spin-flip of an atom in the link. A temperature gradient accelerates the impurity in one direction more than in the other, leading to an overall spin current similar to the spin Seebeck effect.

description: We discuss the phenomenology of damping signatures in the neutrino oscillation probabilities, where either the oscillating terms or the probabilities can be damped. This approach is a possibility for tests of non-oscillation effects in future neutrino oscillation experiments, where we mainly focus on reactor and long-baseline experiments. We extensively motivate different damping signatures due to small corrections by neutrino decoherence, neutrino decay, oscillations into sterile neutrinos, or other mechanisms, and classify these signatures according to their energy (spectral) dependencies. We demonstrate, at the example of short baseline reactor experiments, that damping can severely alter the interpretation of results, e.g., it could fake a value of $\sin(2θ_{13})$ smaller than the one provided by Nature. In addition, we demonstrate how a neutrino factory could constrain different damping models with emphasis on how these different models could be distinguished, i.e., how easily the actual non-oscillation effects could be identified. We find that the damping models cluster in different categories, which can be much better distinguished from each other than models within the same cluster.

description: There is growing interest in voluntary agreements as an economic policy tool for managing environmental risks. Numerous studies have been published about the theory of such arrangements, how they work, and what they accomplish. They demonstrate that voluntary agreements can create value for both regulators and firms. Little has been written, however, that analyzes various voluntary arrangements in the winegrowing sector. The evidence accumulated from other sectors indicates that efforts in the winegrowing sector may be following an appropriate path for attaining management objectives. The California Sustainable Winegrowing Practices (SWP) project indicates a number of strategies that may be useful in developing voluntary agreements in other regions. The recommendations include using an integrated approach with the initiative from the bottom toward the top, involving interest groups early in the process, and evaluating the need for a certification program.

On finite energy solutions of 4-harmonic and ES-4-harmonic maps

Subjects: subject: Differential Geometry (math.DG)

description: 4-harmonic and ES-4-harmonic maps are two generalizations of the well-studied harmonic map equation which are both given by a nonlinear elliptic partial differential equation of order eight. Due to the large number of derivatives it is very difficult to find any difference in the qualitative behavior of these two variational problems. In this article we prove that finite energy solutions of both 4-harmonic and ES-4-harmonic maps from Euclidean space must be trivial. However, the energy that we require to be finite is different for 4-harmonic and ES-4-harmonic maps pointing out a first difference between these two variational problems.
Structure/Function in the CD site of parvalbumin : understanding calcium affinity using synthetic single site EF-hand peptides
Creators: name: Franchini, Patrick Lorenzo Angelo
Publisher: name: University of British Columbia
Year: 2009

description: This study examined the influence of the flanking helices and non-chelating loop residues in the CD site of carp parvalbumin 4.25 (PCD) on calcium ion (Ca²⁺) affinity using synthetic single site EF-hand peptide chimeras based on the sequences of PCD and bovine brain calmodulin site III (Cam3). The peptides are observed to dimerize [Shaw, G.S., Hodges, R.S., and Sykes, B.D. (1990) Science 249, 280-283.] and a mathematical model was developed that described the Ca binding process taking into account dimerization. The model PCD site had 105-fold lower Ca²⁺ affinity than the native site and did not bind magnesium ions. A Glu to Asp replacement in the -X position of the Ca²⁺ binding loop in the PCD model site increased Ca²⁺ affinity suggesting repulsion is a factor in the low Ca²⁺ affinity of the PCD model site. The N-terminal PCD helix gave higher Ca²⁺ affinity than the helix from Cam3 in both the monomer and dimer forms possibly through alterations in the N-terminal helix dipole. The C-terminal PCD helix gave higher Ca²⁺ affinity in the monomer forms and increased monomer negative mean residue ellipticity. This higher Ca²⁺ affinity may be due to enhanced PCD C-terminal helix structure. Both the Cam3 N-terminal helix and the PCD C-terminal helix promoted dimerization possibly through electrostatic interactions. The Gin in non-chelating loop position 2 from PCD does not alter dimerization or Ca²⁺ binding to the monomer or dimer forms compared to Lys. The Lys found in PCD loop position 4 appears to have negative effects on Ca²⁺ affinity in the monomer and dimer forms compared to Gly possibly through restrictive phi/psi angles or a decrease in the negative charge density in the loop. The Glu and Asp residues found in position10 and 11 of the PCD loop promote Ca²⁺ affinity over Ala. This increase may be the result of increased negative charge density in the loop or increased C-terminal helix stability. Preliminary NMR studies support the contention that the PCD model site peptide is a dimer in solution. X-ray diffraction data from a PCD model site peptide crystal has been collected to 1.7 Å resolution.

description: Stein variational gradient descent (SVGD) refers to a class of methods for Bayesian inference based on interacting particle systems. In this paper, we consider the originally proposed deterministic dynamics as well as a stochastic variant, each of which represent one of the two main paradigms in Bayesian computational statistics: emphvariational inference and emphMarkov chain Monte Carlo. As it turns out, these are tightly linked through a correspondence between gradient flow structures and large-deviation principles rooted in statistical physics. To expose this relationship, we develop the cotangent space construction for the Stein geometry, prove its basic properties, and determine the large-deviation functional governing the many-particle limit for the empirical measure. Moreover, we identify the emphStein-Fisher information (or emphkernelised Stein discrepancy) as its leading order contribution in the long-time and many-particle regime in the sense of $Gamma$-convergence, shedding some light on the finite-particle properties of SVGD. Finally, we establish a comparison principle between the Stein-Fisher information and RKHS-norms that might be of independent interest.

description: We show that a sizeable azimuthal asymmetry, characterized by a coefficient v_2, is to be expected for direct photons produced in non-central high energy nuclear collisions. This signal is generated by photons radiated by jets interacting with the surrounding hot plasma. The anisotropy is out of phase by an angle $π/2$ with respect to that associated with the elliptic anisotropy of hadrons, leading to negative values of v_2. Such an asymmetry, if observed, could be a signature for the presence of a quark gluon plasma and would establish the importance of jet-plasma interactions as a source of electromagnetic radiation.

description: To assess the potential role of magnetic fields in regulating the envelope rotation and the fragmentation of Class 0 protostars, we carried out observations of the dust polarized emission at 0.87 mm with the SMA, in the envelopes of a large sample of 20 Class 0 protostars. We estimate the mean magnetic field orientation over the central 1000 au envelope scales and compared it to that of the protostellar outflow in order to study the relation between their misalignment and the kinematics of the circumstellar gas. We discover a strong relationship between the misalignment of the magnetic field orientation with the outflow and the amount of angular momentum observed at similar scales in the protostellar envelope, revealing a potential link between the kinetic and the magnetic energy at envelope scales. The relation could be driven by favored B misalignments in more dynamical envelopes or a dependence of the envelope dynamics with the large-scale B initial configuration. Comparing the trend with the presence of fragmentation, we observe that single sources are mostly associated with conditions of low angular momentum in the inner envelope and good alignment of the magnetic field with protostellar outflows, at intermediate scales. Our results suggest that the properties of the magnetic field in protostellar envelopes bear a tight relationship with the rotating-infalling gas directly involved in the star and disk formation: we find that it may not only influence the fragmentation of protostellar cores into multiple stellar systems, but also set the conditions establishing the pristine properties of planet-forming disks.

description: We show that the well-known divergence of the perturbative expansion of resummed results for processes such as deep-inelastic scattering and Drell-Yan in the soft limit can be treated by Borel resummation. The divergence in the Borel inversion can be removed by the inclusion of suitable higher twist terms. This provides us with an alternative to the standard 'minimal prescription' for the asymptotic summation of the perturbative expansion, and it gives us some handle on the role of higher twist corrections in the soft resummation region.

Hybrid atomic orbital basis from first principles: Bottom-up mapping of self-energy correction to large covalent systems

description: Construction of hybrid atomic orbitals is proposed as the approximate common eigen states of finite first moment matrices. Their hybridization and orientation can be a-priori tunned as per their anticipated neighbourhood. Their Wannier function counterparts constructed from the Kohn-Sham(KS) single particle states constitute an orthonormal multi-orbital tight-binding(TB) basis resembling hybrid atomic-orbitals locked to their immediate atomic neighborhood, while spanning the subs-space of KS states. The proposed basis thus not only renders predominantly single TB parameters from first-principles for each nearest neighbour bonds involving no more than two orbitals irrespective of their orientation, but also facilitate an easy route for transfer of such TB parameters across isostructural systems exclusively through mapping of neighbourhoods and projection of orbital charge centres. With hybridized 2s,2p and 3s,3p valence electrons, the spatial extent of self-energy correction(SEC) to TB parameters in the proposed basis are found to be localized mostly within the third nearest neighbourhood, thus allowing effective transfer of self-energy corrected TB parameters from smaller reference systems to much larger target systems, with nominal additional computational cost beyond that required for explicit computation of SEC in the reference systems. The proposed approach promises inexpensive estimation of quasi-particle structure of large covalent systems with workable accuracy.

description: This paper is based on a study performed by the IPSC-Agrifish unit of Joint Research Centre (JRC) of the European Commission for DG Agriculture under request of the European Parliament. Most information comes from fact sheets collected by experts or consultants in the different countries. The definitions of crisis and disaster eligible for public aid in EU member states are analysed and compared with the "Community guidelines for state aid in the agriculture sector" (EC, 2000). New Commission Guidelines and a new Regulation have been adopted in December 2006. The paper makes a review of the agricultural risks management systems in Europe (EU27) with a special focus on agricultural insurances. The different types of agricultural insurance systems in Europe and key figures in each country are analysed. Some technicalities like reinsurance, triggers and deductibles are described. The relationship between Government involvement and insurance development is highlighted. Usually, private companies insure only hail and fire, but as the government involvement in insurance increases, more comprehensive coverage is provided by the insurance system, becoming possible the insuring of agricultural systemic risks. The role of Governments is analyzed for every country: offering or subsidising insurances and providing aid ex-post. Aid related to risks in agriculture is also given on an ad-hoc basis or through compensation schemes or calamity funds, which can be partially financed by the agricultural sector on a voluntary or compulsory basis. Payments ad-hoc and from calamity funds in most European countries are summarised and their levels are compared. The existing insurance level is generally insufficient to smooth significant income reduction in bad years. Risk management tools available in the MS could be developed further. However, given the heterogeneous situation, the interest of a harmonised EU-wide system of agricultural insurances is debatable. Conditions for a feasible EU-wide insurance scheme are analysed and classified into a) decisions of the policy makers (political criteria); b) decisions of the private sector: insurers, re-insurers and farmers (socio-economic criteria); c) technical conditions. Last, the possible amount of costs of an EU-supported insurance system has been roughly quantified for a few hypothetical scenarios, under given assumptions.

description: Agricultural producers throughout much of the United States experienced one of the most severe droughts in the last 100 years during the years 1999-2006. The prolonged nature of this drought highlights a need to better understand the impacts and management of drought across growing seasons, rather than just within a growing season. Producers express specific concern about the tendency of drought impacts to persist even after drought itself has subsided. The persistence of drought impacts has received limited attention in the economics literature. The objectives of this study are two-fold: 1) to determine whether inter-year dynamics, in the form of agronomic constraints and financial flows, can cause persistence of a drought's impact in years subsequent to the drought, and 2) to determine whether the impact of one year of drought can alter the impact of a subsequent year of drought. A multi-year, dynamic and stochastic decision model is developed in a discrete stochastic programming framework and solved to address the objectives. The structure and parameters of the farm-level model are based on irrigated row crop farms in eastern Oregon, USA. Analysis of the model's solution reveals the following results: 1) the impact of a drought can persist long after the drought subsides, and 2) the impact of one year of drought can alter the impact of a subsequent year of drought. Potential implications for the administration of drought-related assistance are discussed briefly.

description: Fusion-born alpha particles in ITER disruption simulations are investigated as a possible drive of Alfvénic instabilities. The ability of these waves to expel runaway electron (RE) seed particles is explored in the pursuit of a passive, inherent RE mitigation scenario. The spatiotemporal evolution of the alpha particle distribution during the disruption is calculated using the linearized Fokker-Planck solver CODION coupled to a fluid disruption simulation. These simulations are done in the limit of no alpha particle transport during the thermal quench, which can be seen as a most pessimistic situation where there is also no RE seed transport. Under these assumptions, the radial anisotropy of the resulting alpha population provides free energy to drive Alfvénic modes during the quench phase of the disruption. We use the linear gyrokinetic magnetohydrodynamic code LIGKA to calculate the Alfvén spectrum and find that the equilibrium is capable of sustaining a wide range of modes. The self-consistent evolution of the mode amplitudes and the alpha distribution is calculated utilizing the wave-particle interaction tool HAGIS. Intermediate mode number ($n=7-15,~22-26$) Toroidal Alfvén Eigenmodes (TAEs) are shown to saturate at an amplitude of up to $δB /B \approx 0.1$\% in the spatial regimes crucial for RE seed formation. We find that the mode amplitudes are predicted to be sufficiently large to permit the possibility of significant radial transport of runaway electrons.

Whether it is the game of chemical deception played by a micro-organism against an immune system, or the use of camouflage and deception by prey and predator alike in every tier of the natural world, or whether it is some part of the complex structures we use to describe the modern IW/IO paradigm, the fundamental paradigm is essentially one and the same.
The linker of endoglucanase A from cellulomonas fimi: an investigation of structure, function and application
Creators: name: Sandercock, Linda Eileen
Publisher: name: University of British Columbia
Year: 2009

description: Endoglucanase A (CenA), a component o f the multi-enzyme cellulase system o f the bacterium Cellulomonas fimi (C. fimi), is typical of many cellulases, being a multi-domain protein. CenA has two domains which have been well characterized, a catalytic domain and a cellulose-binding domain (CBD) separated by a proline, threonine rich linker (PT linker). This study investigated the structure, function and possible applications of this interdomain linker. Modification of the PT linker's size and composition gave insights into the effect of the linker on hydrolysis of a variety of cellulosic substrates and the nature of its susceptibility to proteolysis. Modifying the linker size and composition had little effect on the hydrolysis rate. Partial deletion reduced activity on crystalline and amorphous celluloses, whereas doubling or replacing it with the fibronectin type III (Fn3) repeats from the endoglucanase B increased the rate of hydrolysis of crystalline cellulose. Altering the linker did not affect activity on 2',4'-dinitrophenyl β-D-cellobioside (2,4-DNPC) except for the Fn3 construct which showed decreased activity. A sequence susceptible to papain and C. fimi protease was defined which could be modified to prevent proteolysis. This has potential implications for the design of linkers for stable CBD-fusion proteins. Examining the glycosylation of CenA produced by C. fimi and Streptomyces lividans (S. lividans) gave insights into eubacterial protein glycosylation. Glycosylation was confined to the PT linker at sites conforming to an O-glycosylation consensus sequence for some mammalian glycoproteins. The oligosaccharide composition was dependent on the host, but the glycosylation mechanism is likely similar as they discriminated between the same protein features. Oligosaccharide size and linkage information for biose units of S. lividans produced proteins were determined, the latter by a novel application of fluorophore-assisted carbohydrate electrophoresis. Glycosylation slowed proteolysis and slightly reduced the activity on 2,4-DNPC. The CenA linker resembles the hinge of human immunoglobulin A1 (IgA1). A hybrid protein, CenAIgA1h - where the PT linker was replaced by the IgA1 hinge- and CenA were useful substrates for probing the specificity of a number of IgA1 proteases produced by a variety of pathogenic bacteria. The most striking finding was that only one of two IgA1 proteases which have high sequence identity and cleave the identical bond in IgA1, cleaved CenA. These substrates will be useful in future studies of IgA1 protease specificity.

description: Basis risk has been cited as a primary concern for implementing weather hedges. This study investigates several dimensions of weather basis risk for the U.S. corn market at various levels of aggregation. The results suggest that while the degree of geographic basis risk may be significant in some instances, it should not preclude the use of geographic cross-hedging. In addition, the degree to which geographic basis risk impedes effective hedging diminishes as the level of spatial aggregation increases. In fact, geographic basis risk is actually negative in the case most representative of a reinsurance hedge, and the reduction in risk from employing straightforward temperature derivatives is significant. Finally, precipitation hedges are found to introduce additional product basis risk. The findings may be of interest to decision makers considering using exchange traded weather derivatives to hedge agricultural production and insurance risk.

description: Climate science has made enormous progress over the last two decades in understanding the nature of earth's climate and the changes that are taking place. Under climate change projections, we can say with some confidence that the Australian climate will continue to become hotter, and temperature-related extreme events are likely to increase in frequency. However, we cannot yet project with any reasonable level of confidence changes to rainfall and the occurrence of drought. So although there is strong evidence for the reality of climate change, there is still considerable uncertainty associated with projections of precisely how climate change will unfold in the future, particularly at regional and local scales where most farming management decisions are made. Adapting to such an uncertain future demands a flexible approach based on assessing, analysing and responding to the risks posed by a changing climate. This paper examines a risk management approach to farming in a variable and changing climate, based on experience gained in the insurance industry which is one of the first major industries to be impacted by climate change losses. Governments, businesses and individuals must consider the implications of a variable and changing climate as a normal part of decision-making based on risk, just as they would for other risks, such as market price and fuel price movements, labour costs etc. The paper also discusses briefly how advances in information technology have enabled information to be accessed and widely distributed, and showcases four best practice spatial IT website tools developed by the BRS to assist farmers and policy makers to manage risk - the National Agricultural Monitoring System (NAMS), the Meat and Livestock Australia (MLA) Rainfall to Pasture Growth Outlook Tool, the Multi-Criteria Analysis Shell (MCAS-S), and the Rainfall Reliability Wizard. There are also several tools under current development in BRS which continue with this theme. These are Water 2010 - National Water Balance and Information for Policy and Planning, the Climate Change Wizard and Climate Change Impacted Data Sets.

description: We study the CP violation in two-body nonleptonic decays of $B_c$ meson. We concentrate on the decay channels which contain at least one excited heavy meson in the final states. Specifically, the following channels are considered: $B_c\to c\bar c(2S, 2P)+\bar cq(1S, 1P)$, $B_c\to c\bar c(1S)+\bar cq(2S, 2P)$, $B_c\to c\bar c(1P)+\bar cq(2S)$, $B_c\to c\bar c(1D)+\bar cq(1S, 1P)$, and $B_c\to c\bar c(3S)+\bar cq(1S)$. The improved Bethe-Salpeter method is applied to calculate the hadronic transition matrix element. Our results show that some decay modes have large branching ratios, which is of the order of $10^{-3}$. The CP violation effect in $B_c \rightarrow η_c(1S)+D(2S)$, $B_c \rightarrow η_c(1S)+D_0^{*}(2P)$, and $B_c \rightarrow J/ψ+D^{*}(2S)$ are most likely to be found. If the detection precision of the CP asymmetry in such channels can reach the $3σ$ level, at least $10^7$ $B_c$ events are needed.

description: Global and climate changes influence the basic conditions for agriculture and so there is not only a demand for a consequent climate protection but also for an adaptation of agriculture to these global changing conditions. For the whole "Maerkisch-Oderland" district (60x40 km) within the moraine landscape of North-East-Germany mainly used for agriculture water balance, nitrogen and sulphur loads as well as crop yields are calculated for two land use and climate scenarios. The comparison between the Scenario2050 and the Scenario2000 reveals significant changes of the water balance (decrease in percolation water, increase in actual evapotranspiration) as well as the concentration of the examined nitrogen in the percolation water. For the study region the crop yields decrease only slightly if the CO2 fertilizing effect is taken into account. Adaptation measures in reaction to the changing climate conditions for an economically secured and sustainable agriculture are recommended.

description: VIRGOHI21 is an HI source detected in the Virgo Cluster survey of Davies et al. (2004) which has a neutral hydrogen mass of 10^8 M_solar and a velocity width of Delta V_20 = 220 km/s. From the Tully-Fisher relation, a galaxy with this velocity width would be expected to be 12th magnitude or brighter; however deep CCD imaging has failed to turn up a counterpart down to a surface-brightness level of 27.5 B mag/sq. arcsec. The HI observations show that it is extended over at least 16 kpc which, if the system is bound, gives it a minimum dynamical mass of ~10^11 M_solar and a mass to light ratio of M_dyn/L_B > 500 M_solar/L_solar. If it is tidal debris then the putative parents have vanished; the remaining viable explanation is that VIRGOHI21 is a dark halo that does not contain the expected bright galaxy. This object was found because of the low column density limit of our survey, a limit much lower than that achieved by all-sky surveys such as HIPASS. Further such sensitive surveys might turn up a significant number of the dark matter halos predicted by Dark Matter models.

description: Global and hemispheric climate indicators have proved useful in many countries for characterising intra- and inter-annual variability in climate processes, agricultural output and biomass production. They also form the basis of successful seasonal climate and production prediction systems for the probability distributions of allied parameters such as rainfall or crop yield. Climate risk management via derivative, insurance or bond instruments has only recently incorporated non-local climate parameters such as "teleconnection" indices in payoff functions and overall design. A feasibility study of using the Southern Oscillation Index in weather derivatives for the Australian wheat industry has suggested several such climate-anomaly indicators as suitable vehicles for managing risks of various types, including the hedging of likely errors in seasonal climate forecasting. The potential benefits should accrue if the co-joining of weather/climate risk management and seasonal forecasting is encouraged across many weather-sensitive industries (e.g. agriculture, mining, energy and tourism), if longer-term perspectives of risk across many seasons are adopted and if support is given to suitable trading mechanisms and industry extension programmes.
