description: We propose the realization of custom-designed adiabatic potentials for cold atoms based on multimode radio frequency radiation in combination with static inhomogeneous magnetic fields. For example, the use of radio frequency combs gives rise to periodic potentials acting as gratings for cold atoms. In strong magnetic field gradients the lattice constant can be well below 1 micrometer. By changing the frequencies of the comb in time the gratings can easily be propagated in space, which may prove useful for Bragg scattering atomic matter waves. Furthermore, almost arbitrarily shaped potential are possible such as disordered potentials on a scale of several 100 nm or lattices with a spatially varying lattice constant. The potentials can be made state selective and, in the case of atomic mixtures, also species selective. This opens new perspectives for generating tailored quantum systems based on ultra cold single atoms or degenerate atomic and molecular quantum gases.

description: We propose the mechanism for the magnetic-field-induced antiferromagnetic (AFM) state in a two-dimensional Hubbard model in the vicinity of the AFM quantum critical point (QCP), using the fluctuation-exchange (FLEX) approximation by taking the Zeeman energy due to the magnetic field $B$ into account. In the vicinity of the QCP, we find that the AFM correlation perpendicular to $B$ is enhanced, whereas that parallel to $B$ is reduced. This fact means that the finite magnetic field increases $T_N$, with the AFM order perpendicular to $B$. The increment in $T_N$ can be understood in terms of the reduction of both quantum and thermal fluctuations due to the magnetic field, which is caused by the self-energy effect within the FLEX approximation. The present study naturally explains the increment in $T_N$ in CeRhIn_5 under the magnetic field found recently.

description: Corn production uses over 25 percent of the Nation's cropland and more than 40 percent of the commercial fertilizer applied to crops. Thus, corn farmers' choices of soil, nutrient, and water management systems can have a major impact not only on their own profitability, but also on the environment. If sound economic and environmental choices are to be encouraged, it may help to assess relationships between operator and farm characteristics and the adoption of management techniques by corn farmers. Data from the 1996 Agricultural Resource Management Survey (ARMS) of U.S. corn farms and producers are analyzed for this purpose, supplemented by a literature survey on factors that influence corn farm management choices. Relationships were found between certain socioeconomic variables, including farmer age and education and size of the operation, and implementation of management practices. This is the first study to relate corn farm management choices, on a national scale, to so broad a set of characteristics.

description: We show that a static electric field induces the transition from a ferromagnetic metal to an antiferromagnetic insulator owing to the Bloch oscillation of conduction electrons. In the steady state, the electric current is inversely proportional to the applied electric field, implying the nonperturbative insulating nature that is different from the Wannier-Stark localization. Possible experimental realization based on recent terahertz pulse sources is discussed.

description: We consider the quantum spin-$s$ $XXZ$ Heisenberg antiferromagnet on the two- and three-dimensional pyrochlore lattices and examine a spin-Peierls mechanism of lowering the total energy by a lattice distortion in a high magnetic field. For the exact eigenstates consisting of several independent localized magnons in a ferromagnetic environment we show the existence of a spin-Peierls instability by rigorous analytical calculations. In addition we report on exact diagonalization data for finite two-dimensional pyrochlore lattices up to N=64 sites. We discuss a scenario of the field-tuned changes in the ground-state properties of the frustrated spin lattices due to the coupling between spin and lattice degrees of freedom.

description: Agricultural chemicals and sediment from cropland may reduce the quality of America's surface and ground water resources. The Clean Water Act stipulates that individual States are responsible for controlling agricultural nonpoint source pollution. Most State plans rely chiefly on education and technical assistance to promote the adoption of less polluting practices. Because profitability drives production decisions, these programs tend to be most successful when they promote inexpensive changes in existing practices. This report presents research findings on the success of incentive programs to control agricultural nonpoint source pollution.

description: Perturbations in a Chaplygin gas, characterized by an equation of state $p = -A/ρ$, may acquire non-adiabatic contributions if spatial variations of the parameter $A$ are admitted. This feature is shown to be related to a specific internal structure of the Chaplygin gas. We investigate how perturbations of this type modify the adiabatic sound speed and influence the time dependence of the gravitational potential which gives rise to the Integrated Sachs-Wolfe effect in the anisotropy spectrum of the cosmic microwave background.

Mechanistic studies of chondroitin AC lyase from Flavobacterium heparinum
Creators: name: Rye, Carl S.
Publisher: name: University of British Columbia
Year: 2009

description: Chondroitin AC lyase from Flavobacterium heparinum degrades chondroitin sulfate glycosaminoglycans via an elimination mechanism resulting in disaccharides or oligosaccharides with Δ4,5-unsaturated uronic acid residues at their non-reducing end. A general mechanism for all polysaccharide lyases has been proposed, however no mechanistic details exist, mainly due to the inhomogeneous nature of the polymeric substrates available, which renders impossible the collection of reliable and reproducible data. Thus, three different types of substrate were developed that can be monitored by three different techniques: UV/Vis spectroscopy, fluorescence spectroscopy, and by the use of a fluoride ion-selective electrode. These synthetic substrates have allowed the measurement of defined and reproducible kinetic parameters previously unavailable using the polymeric natural substrates. The creation of this new class of structurally defined substrates has allowed their modification in order to carry out a variety of mechanistic analyses aimed at deciphering the exact catalytic mechanism of chondroitin AC lyase. A combination of primary and secondary deuterium kinetic isotope effects together with a linear free energy relationship has revealed the details regarding the order of the bond breaking and making steps of the enzymatic reaction. These mechanistic studies have revealed the reaction mechanism to be stepwise, including a rate-limiting proton abstraction followed by a facile elimination of the C4-linked leaving group. In addition, a solvent isotope exchange experiment has revealed that the exchange of deuterium at C5 does not compete with the departure of the leaving group, thus classifying the elimination mechanism as (Elcb)^ or (Elcb)i in which the proton abstraction step is essentially irreversible. Tight binding inhibitors, in conjunction with X-ray crystallography, may allow the identification of key catalytic residues responsible for binding and catalysis. There are no known specific inhibitors of polysaccharide lyases reported in the literature, prompting investigation into this area. Two potential inhibitors of chondroitin AC lyase were synthesized, based on two different design concepts. The first, a disaccharide molecule containing a pre-formed C4-C5 alkene moiety in combination with an intact hexosamine leaving group sugar residue, surprisingly showed no inhibition. The second potential inhibitor was a novel 5-nitro sugar, designed to mimic the ac/-carboxylate intermediate along the reaction pathway. This compound was found to be a competitive inhibitor of the enzyme with a K; value of ~ 0.7 mM. Unfortunately this relatively large inhibition constant is not representative of a transition state analogue, which would be expected to bind much tighter to the enzyme.
First measurement of the rho spectral function in nuclear collisions

description: The NA60 experiment has studied low-mass muon pairs in 158 AGeV Indium-Indium collisions at the CERN SPS. A strong excess of pairs is observed above the expectation from neutral meson decays. The unprecedented sample size of 360 000 events and the good mass resolution of about 2% allow to isolate the excess by subtraction of the known sources. The shape of the resulting mass spectrum is consistent with a dominant contribution from pi+ pi- -> rho -> mu+ mu- annihilation. The associated rho spectral function shows a strong broadening, but essentially no shift in mass.

description: In recent years, cosmic shear has emerged as a powerful tool to study the statistical distribution of matter in our Universe. Apart from the standard two-point correlation functions, several alternative methods like peak count statistics offer competitive results. Here we show that persistent homology, a tool from topological data analysis, can extract more cosmological information than previous methods from the same dataset. For this, we use persistent Betti numbers to efficiently summarise the full topological structure of weak lensing aperture mass maps. This method can be seen as an extension of the peak count statistics, in which we additionally capture information about the environment surrounding the maxima. We first demonstrate the performance in a mock analysis of the KiDS+VIKING-450 data: we extract the Betti functions from a suite of $w$CDM $N$-body simulations and use these to train a Gaussian process emulator that provides rapid model predictions; we next run a Markov-Chain Monte Carlo analysis on independent mock data to infer the cosmological parameters and their uncertainty. When comparing our results, we recover the input cosmology and achieve a constraining power on $S_8 \equiv σ_8\sqrt{Ω_\mathrm{m}/0.3}$ that is 5% tighter than that of peak count statistics. Performing the same analysis on 100 deg$^2$ of Euclid-like simulations, we are able to improve the constraints on $S_8$ and $Ω_\mathrm{m}$ by 18% and 10%, respectively, while breaking some of the degeneracy between $S_8$ and the dark energy equation of state. To our knowledge, the methods presented here are the most powerful topological tools to constrain cosmological parameters with lensing data.

description: A general hamiltonian $H$ of electrons in finite concentration, interacting via any two-body coupling inside a crystal of arbitrary dimension, is considered. For simplicity and without loss of generality, a one-band model is used to account for the electron-crystal interaction. The electron motion is described in the Hilbert space $S_ϕ$, spanned by a basis of Slater determinants of one-electron Bloch wave-functions. Electron pairs of total momentum $K$ and projected spin $ζ=0,\pm1$ are considered in this work. The hamiltonian then reads $H=H_D+\sum_{K,ζ}H_{K,ζ}$, where $H_D$ consists of the diagonal part of $H$ in the Slater determinant basis. $H_{K,ζ}$ describes the off-diagonal part of the two-electron scattering process which conserves $K$ and $ζ$. This hamiltonian operates in a subspace of $S_ϕ$, where the Slater determinants consist of pairs characterised by the same $K$ and $ζ$. It is shown that the whole set of eigensolutions $ψ, ε$ of the time-independent Schrödinger equation $(H-ε)ψ=0$ divides in two classes, $ψ_1,ε_1$ and $ψ_2,ε_2$. The eigensolutions of class 1 are characterised by the property that for each solution $ψ_1,ε_1$ there is a single $K$ and $ζ$ such that $(H_D+H_{K,ζ}-ε_1)ψ_{K,ζ}=0$ where in general $ψ_1 \ne ψ_{K,ζ}$, whereas each solution $ψ_2,ε_2$ of class 2 fulfils $(H_D-ε_2)ψ_2=0$. We prove also that the eigenvectors of class 1 have off-diagonal long-range order whereas those of class 2 do not. Finally our result shows that off-diagonal long-range order is not a sufficient condition for superconductivity.

description: Ecosystem services generate benefits that enter human consumption either directly or indirectly via their contribution to human production activities. In this contribution, we provide evidence that (i) the demand of peasants for ecosystem services in rural Indonesia depends on relative poverty; and that (ii) the type of reaction to poverty depends on the specific relation of the ecosystem services to peasant production and consumption. In early 2005 a representative choice experiment study was conducted in the Lore Lindu area in Central Sulawesi, Indonesia, to quantify regional economic preferences (marginal willingessto- pay: MWTP) for four different ecosystem services (n=249; rattan and water availability, shading in cacao agroforestry, population size of the endemic forest dwelling dwarf buffalo "anoa"). Relative poverty was calculated with the 2005 data using a 0,1-normally distributed relative poverty index developed from a socio-demographic household survey administered to the same sample in 2004. For shading in cocoa, a linearly decreasing trend is observed indicating a stronger preference for "sun-grown" cocoa in the less poor farmers indicating a constant poverty elasticity of WTP. The empirical poverty elasticity for anoa supports its luxury good characteristic only in part. For rattan and water, we find an inverted U-shape relation between MWTP for ecosystem services and relative poverty - probably due to serious restrictions in the ability to pay in the poorest households and a smaller resource dependency in the less poor households. In sum, the relationship between relative poverty and MWTP for ecosystem services appears more complex than classical micro-economic theory admits.

description: This paper investigates the impact of the dissemination of modern irrigation systems, i.e. private wells with pumps, on the livelihood not only among the farmers who have access to wells but also among the farmers who have no access to wells and thus rely solely on traditional irrigation systems called tank irrigation systems. The analysis is based on a village and household data set collected in Tamil Nadu, India where tank irrigation systems have been managed collectively for rice cultivation. Our statistical analyses predict that once declines in collective management occur due to the dissemination of private wells, the rice yield and income of the no-well-access farmers alone will decrease, resulting in increased poverty among them. Our analyses also find that the dissemination leads to the overexploitation of groundwater, and thus results in no significant increase in rice profit among the well-access farmers. In this way, the dissemination of private wells creates double tragedies: not only increased poverty among the no-well-access farmers but also overexploitation and profit reduction among the well-access farmers.

description: We study the difference between thermally produced fermionic and bosonic hot dark matter in detail. In the linear regime of structure formation, their distinct free-streaming behaviours can lead to pronounced differences in the matter power spectrum. While not detectable with current cosmological data, such differences will be clearly observable with upcoming large scale weak lensing surveys for particles as light as m_HDM ~ 0.2 eV. In the nonlinear regime, bosonic hot dark matter is not subject to the same phase space constraints that severely limit the amount of fermionic hot dark matter infall into cold dark matter halos. Consequently, the overdensities in fermionic and bosonic hot dark matter of equal particle mass can differ by more than a factor of five in the central part of a halo. However, this unique manifestation of quantum statistics may prove very difficult to detect unless the mass of the hot dark matter particle and its decoupling temperature fall within a very narrow window, 1 < m_HDM/eV < 4 and g* < 30. In this case, hot dark matter infall may have some observable consequences for the nonlinear power spectrum and hence the weak lensing convergence power spectrum at l ~ 10^3 - 10^4 at the percent level.

We also describe a number of systematic improvements to our previous lattice studies, including working with larger $m_πL$ to better suppress possible finite volume effects, employing extended sinks to better control excited-state contamination, and expanding the number of operators used in the GEVP analyses. Our results also allow us to rule out several phenomenological models which predict significant tetraquark binding in channels where no such binding is found.

The result for GNO III (last 15 solar runs) is [54.3 + 9.9 - 9.3 (stat.)+- 2.3 (syst.)] SNU (1 sigma) or [54.3 + 10.2 - 9.6 (incl. syst.)] SNU (1 sigma) with errors combined. The GNO experiment is now terminated after altogether 58 solar exposure runs that were performed between May 20, 1998 and April 9, 2003. The combined result for GNO (I+II+III) is [62.9 + 5.5 - 5.3 (stat.) +- 2.5 (syst.)] SNU (1 sigma) or [62.9 + 6.0 - 5.9] SNU (1 sigma) with errors combined in quadrature. Overall, gallium based solar observations at LNGS (first in GALLEX, later in GNO) lasted from May 14, 1991 through April 9, 2003. The joint result from 123 runs in GNO and GALLEX is [69.3 +- 5.5 (incl. syst.)] SNU (1 sigma). The distribution of the individual run results is consistent with the hypothesis of a neutrino flux that is constant in time. Implications from the data in particle- and astrophysics are reiterated.

description: The success of the identification of the planar dilatation operator of N=4 SYM with an integrable spin chain Hamiltonian has raised the question if this also is valid for a deformed theory. Several deformations of SYM have recently been under investigation in this context. In this work we consider the general Leigh-Strassler deformation. For the generic case the S-matrix techniques cannot be used to prove integrability. Instead we use R-matrix techniques to study integrability. Some new integrable points in the parameter space are found.

Despite long integration times, the binary (composed of T1 and T6 dwarfs) was not detected in either wavelength regime. We reached $3σ$ upper limits of $1.23 \times 10^{12}$ and $1.74 \times 10^{12}$ erg/s/Hz for the radio luminosity at 4.8 GHz and 8.64 GHz, respectively; in the X-rays, the upper limit in the $0.1-10$ keV band was $3.16 \times 10^{23}$ erg/s.

description: This paper investigates the roles of industrial cluster on the efficiency of rice milling and the improvement of milled rice quality. The data were obtained in Kumasi area, central Ghana because the enhancement of domestic rice production is a urgent policy issue in this country, but little attention has been paid to the roles of clusters in post-harvest processing and marketing. Among 63 rice millers interviewed in the Kumasi area, 24 millers form a few clusters in the city of Kumasi, while others are scattered over 25 satellite towns around Kumasi, which enables us to examine the effect of the cluster. Regression analyses reveal that rice millers in the Kumasi clusters tend to adopt more advanced technology, and that the innovation increases milling efficiency and improves 1 milling quality. Moreover, it is found from the estimation of price determination functions that in the Kumasi clusters milled rice price is affected by milling quality namely the content of whole grain, while in the rural areas there is no clear relationship between milling quality and the price. This indicates that the clusters, probably because of the concentrated transactions, will foster informal quality grading system, which is critical for the market development. Therefore, the clusters in post-harvest industry will benefit not only the industry itself but also traders and producers, and in consequence will stimulate agricultural production.

description: Unambiguous identification of the superconducting order parameter symmetry of Sr$_2$RuO$_4$ has remained elusive for more than a quarter century. While a chiral $p$-wave ground state analogue to superfluid $^3$He-$A$ was ruled out only very recently, other proposed $p$-wave scenarios are still viable. Here, field-dependent $^{17}$O Knight shift measurements are compared to corresponding specific heat measurements, previously reported. We conclude that the shift results can be accounted for by the expected field-induced quasiparticle response only. An upper bound for the condensate magnetic response of $<10\%$ of the normal state susceptibility is sufficient to exclude odd-parity candidates.

description: Ultrafast optics is an important field of study for chemistry and physics, providing new information on the dynamics of matter and electrons. In this thesis I describe my work on ultrafast laser systems. The two main systems discussed are a high harmonic generated extreme ultraviolet system and a terahertz spectroscopy system. The first half describes the importance and background of both as well as how these systems are set up. The second half describes my work in designing and implanting these systems, and my work in constructing components for the operation of both.

description: Based on the {\it dynamical} equivalence between higher order gravity and scalar-tensor gravity the PPN-limit of fourth order gravity is discussed. We exploit this analogy developing a fourth order gravity version of the Eddington PPN-parameters. As a result, Solar System experiments can be reconciled with higher order gravity, if physical constraints descending from experiments are fulfilled.

Systematic Policy Decisions on Direct Income Payments in Agricultural Policies

description: Direct income payments (DIP) are in the centre of the discussion in the ongoing political debate whether agricultural policy objectives can be pursued in an economically more efficient and less distorting way. This paper discusses under which circumstances DIP are an appropriate and efficient measure to address the objectives of agricultural policies. It identifies and examines the characteristics that DIP should have in the context of different objectives. If governments want to meet their policy objectives by the use of DIP efficiently, a precise definition of the objective is crucial. An optimal policy design achieves a specific objective while keeping the impact on economic distortions low and ensuring efficiency in the allocation of resources. The decision tree for DIP presented in this paper contributes to a more systematic approach to the topic and facilitates the policy design for a sustainable and resource saving economic policy in the field of agriculture. We show that DIP can be used to address different types of policy objectives, but have to be adapted carefully depending on the specific targets. If used as a measure to compensate income losses due to policy changes, DIP could help farmers to adjust to policy changes in an efficient way and, at the same time, release budget funds. Such gains could then be used in and tied to areas that are known to be crucial but currently lack resources due to budget restrictions - e.g. the provision of environmental goods and services, which can also be addressed by DIP.
Chiral Separation effect in non-homogeneous systems

description: We discuss chiral separation effect in the systems with spatial non - homogeneity. It may be caused by non - uniform electric potential or by another reasons, which do not, however, break chiral symmetry of an effective low energy theory. Such low energy effective theory describes quasiparticles close to the Fermi surfaces. In the presence of constant external magnetic field the non - dissipative axial current appears. It appears that its response to chemical potential and magnetic field (the CSE conductivity) is universal. It is robust to smooth modifications of the system and is expressed through an integral over a surface in momentum space that surrounds all singularities of the Green function. In itself this expression represents an extension of the topological invariant protecting Fermi points to the case of inhomogeneous systems.

description: We discuss a conjecture which says that the automorphism group of the Weyl algebra in characteristic zero is canonically isomorphic to the automorphism group of the corresponding Poisson algebra of classical polynomial symbols. Several arguments in favor of this conjecture are presented, all based on the consideration of the reduction of the Weyl algebra to positive characteristic.

description: Potatoes are marketed by type (i.e. round white, russet, red, etc.), rather than by variety. However, the round white varieties currently marketed by the Maine potato industry are known to differ considerably in terms of product characteristics. This study was designed to test the hypothesis that consumer acceptance of potatoes in home use varies by variety and to quantify how their level of acceptance and other characteristics impact their repurchase decision. A discrete choice model was used. The results indicated that consumers do differentiate round white potato varieties based on the performance of the potatoes in home use. Their willingness to repurchase the round white potatoes is affected by the variety used and the overall serving quality of the potatoes in home use.

description: We report active tuning of the polariton resonance of quantum well excitons in a semiconductor microcavity using applied stress. Starting with the quantum well exciton energy higher than the cavity photon mode, we use stress to reduce the exciton energy and bring it into resonance with the photon mode. At the point of zero detuning, line narrowing and strong increase of the photoluminescence are seen. By the same means, we create an in-plane harmonic potential for the polaritons, which allows trapping, potentially making Bose-Einstein condensation of polaritons analogous to trapped atoms possible. We demonstrate drift of the polaritons into this trap.

description: We study the quantum mechanical correlation between two identical neutralinos in the decays of minimal supersymmetric standard model (MSSM) scalar tau (stau) pair produced in e+e- annihilation. Generally, the decay products of scalar (spinless) particles are not correlated. We show that a correlation between two neutralinos appears near pair production threshold, due to a finite stau width and mixing of the staus and/or neutralinos, and because the neutralinos are Majorana. Because the correlation is significant only in a specific kinematical configuration, it can be observed only in supersymmetric models where the neutralino momenta can be kinematically reconstructed, such as in models with R-parity violation.

description: Non-abelian gauge theories in the Higgs phase admit a startling variety of BPS solitons. These include domain walls, vortex strings, confined monopoles threaded on vortex strings, vortex strings ending on domain walls, monopoles threaded on strings ending on domain walls, and more. After presenting a self-contained review of these objects, including several new results on the dynamics of domain walls, we go on to examine the possible interactions of solitons of various types. We point out the existence of a classical binding energy when the string ends on the domain wall which can be thought of as a BPS boojum with negative mass. We present an index theorem for domain walls in non-abelian gauge theories. We also answer questions such as: Which strings can end on which walls? What happens when monopoles pass through domain walls? What happens when domain walls pass through each other?
