description: A mixture of spin-polarized light and heavy fermionic atoms on a finite size 2D optical lattice is considered at various temperatures and values of the coupling between the two atomic species. In the case, where the heavy atoms are immobile in comparison to the light atoms, this system can be seen as a correlated binary alloy related to the Falicov-Kimball model. The heavy atoms represent a scattering environment for the light atoms. The distributions of the binary alloy are discussed in terms of strong- and weak-coupling expansions. We further present numerical results for the intermediate interaction regime and for the density of states of the light particles. The numerical approach is based on a combination of a Monte-Carlo simulation and an exact diagonalization method. We find that the scattering by the correlated heavy atoms can open a gap in the spectrum of the light atoms, either for strong interaction or small temperatures.

description: Using tensor network methods, we perform finite-size scaling analysis to study the parameter-induced phase transitions of two-dimensional deformed Affleck-Kennedy-Lieb-Tasaki states. We use higher-order tensor renormalization group method to evaluate the moments and the correlations. Then, the critical point and critical exponents are determined simultaneously by collapsing the data. Alternatively, the crossing points of the dimensionless ratios are used to determine the critical point, and the scaling at the critical point is used to determine the critical exponents. For the transition between the disordered AKLT phase and the ferromagnetic ordered phase, we demonstrate that both the critical point and the exponents can be determined accurately. Furthermore, the values of the exponents confirm that the AKLT-FM transition belongs to the 2D Ising universality class. We also investigate the Berezinskii-Kosterlitz-Thouless transition from the AKLT phase to the critical XY phase. In this case we show that the critical point can be located by the crossing point of the correlation ratio.

description: Markets for zero-day exploits (software vulnerabilities unknown to the vendor) have a long history and a growing popularity. We study these markets from a revenue-maximizing mechanism design perspective. We first propose a theoretical model for zero-day exploits markets. In our model, one exploit is being sold to multiple buyers. There are two kinds of buyers, which we call the defenders and the offenders. The defenders are buyers who buy vulnerabilities in order to fix them (e.g., software vendors). The offenders, on the other hand, are buyers who intend to utilize the exploits (e.g., national security agencies and police). Our model is more than a single-item auction. First, an exploit is a piece of information, so one exploit can be sold to multiple buyers. Second, buyers have externalities. If one defender wins, then the exploit becomes worthless to the offenders. Third, if we disclose the details of the exploit to the buyers before the auction, then they may leave with the information without paying. On the other hand, if we do not disclose the details, then it is difficult for the buyers to come up with their private valuations. Considering the above, our proposed mechanism discloses the details of the exploit to all offenders before the auction. The offenders then pay to delay the exploit being disclosed to the defenders.

description: Advective trapping occurs when solute enters low velocity zones in heterogeneous porous media. Classical local modeling approaches combine the impact of slow advection and diffusion into a hydrodynamic dispersion coefficient and many temporally non-local approaches lump these mechanisms into a single memory function. This joint treatment makes parameterization difficult and thus prediction of large scale transport a challenge. Here we investigate the mechanisms of advective trapping and their impact on transport in media composed of a high conductivity background and isolated low permeability inclusions. Breakthrough curves show that effective transport changes from a streamtube-like behavior to genuine random trapping as the degree of disorder of the inclusion arrangement increases. We upscale this behavior using a Lagrangian view point, in which idealized solute particles transition over a fixed distance at random advection times combined with Poissonian advective trapping events. We discuss the mathematical formulation of the upscaled model in the continuous time random walk and mobile-immobile mass transfer frameworks, and derive a model for large scale solute non-Fickian dispersion. These findings give new insight into transport in highly heterogeneous media.

description: The smallness of the baryon asymmetry in our universe is one of the greatest mysteries and may originate from some profound physics beyond the standard model. We investigate the Affleck-Dine baryogenesis in split supersymmetry, and find that the smallness of the baryon asymmetry is directly related to the hierarchy between the supersymmetry breaking squark/slepton masses and the weak scale. Put simply, the baryon asymmetry is small because of the split mass spectrum.

description: Optimizing within the affine maximizer auctions (AMA) is an effective approach for revenue maximizing mechanism design. The AMA mechanisms are strategy-proof and individually rational (if the agents' valuations for the outcomes are nonnegative). Every AMA mechanism is characterized by a list of parameters. By focusing on the AMA mechanisms, we turn mechanism design into a value optimization problem, where we only need to adjust the parameters. We propose a linear programming based heuristic for optimizing within the AMA family. We apply our technique to revenue maximizing mechanism design for zero-day exploit markets. We show that due to the nature of the zero-day exploit markets, if there are only two agents (one offender and one defender), then our technique generally produces a near optimal mechanism: the mechanism's expected revenue is close to the optimal revenue achieved by the optimal strategy-proof and individually rational mechanism (not necessarily an AMA mechanism).

description: Magnetization reversal in exchange-spring magnet films has been investigated by a First Order Reversal Curve (FORC) technique and vector magnetometry. In Fe/epitaxial-SmCo films, the reversal proceeds by a reversible rotation of the Fe soft layer, followed by an irreversible switching of the SmCo hard layer. The switching fields are clearly manifested by separate steps in both longitudinal and transverse hysteresis loops, as well as sharp boundaries in the FORC distribution. In FeNi/polycrystalline-FePt films, particularly with thin FeNi, the switching fields are masked by the smooth and step-free major loop. However, the FORC diagram still displays a distinct onset of irreversible switching and transverse hysteresis loops exhibit a pair of peaks, whose amplitude is larger than the maximum possible contribution from the FeNi layer alone. This suggests that the FeNi and FePt layers reverse in a continuous process via a vertical spiral. The successive vs. continuous rotation of the soft/hard layer system is primarily due to the different crystal structure of the hard layer, which results in different anisotropies.

description: American consumers are exposed to thousands of new food products on supermarket shelves each year. For new products, such as akara products, it is crucial to determine consumer preferences and buying intentions. In this study, 346 randomly selected consumers were surveyed to reveal their preference for five akara products prepared from cowpea flour. Preference data were analyzed through use of a multi-ordered response model. Model results indicate that socio-demographic factors were weakly linked to explaining consumer preferences while product characteristics were much more important in preference considerations.

description: We present a new multiwavelength analysis of the Coma cluster subclustering based on recent X-ray data and on a compilation of nearly 900 redshifts. We characterize subclustering using the Serna&Gerbal (1996) hierarchical method which makes use of galaxy positions, redshifts, and magnitudes, and identify 17 groups. One of these groups corresponds to the main cluster, one is the well known group associated with the infalling galaxy NGC4839 and one is associated with NGC4911/NGC4926. About one third of the 17 groups have velocity distributions centered on the velocities of the very bright cluster galaxies they contain (magnitudes R<13). In order to search for additional substructures, we make use of the isophotes of X-ray brightness residuals left after the subtraction of the best-fit beta-model from the overall X-ray gas distribution (Neumann et al. 2003). We select galaxies within each of these isophotes and compare their velocity distributions with that of the whole cluster. We confirm in this way the two groups associated, respectively, with NGC4839, and with the southern part of the extended western substructure visible in X-rays. We discuss the group properties in the context of a scenario in which Coma is built by the accretion of groups infalling from the surrounding large scale structure. We estimate the recent mass accretion rate of Coma and compare it with hierarchical models of cluster evolution.

The results indicate that the group members perceived all russets as "Idaho" potatoes, associated the red potatoes with gourmet meals, and viewed the round whites as generic potatoes, unsuitable for company meals. However, participants identified round whites as their personal favorite and as the kind they purchased most often.

description: In type-I superconducting cylinders bulk superconductivity is destroyed above the first critical current. Below the second critical current the `type-I mixed state' displays fluctuation superconductivity which contributes to the total current. A magnetic flux on the axis of the cylinder can change the second critical current by as much as 50 percent so that half a flux quantum can switch the cylinder from normal conduction to superconductivity: the Aharonov--Bohm effect manifests itself in macroscopically large resistance changes of the cylinder.

description: This paper employs the dual approach to trace the impact of public policy instruments upon the operational and financial performance of U.S. dairy cooperatives. A restricted profit function is applied to the Operations and Finance Statements for years 1980-1988 of thirty major dairy cooperatives. The data set for this study is provided by the Agricultural Cooperatives Service, USDA. A specification search such as described in Mountain and Hsaio (1989) is conducted to ensure the most appropriate fit for the data provided. From the estimated parameters, output supply and factor demand elasticities will be obtained by way of well-known functional relationships. From these elasticities, the short-run effect of any change in Federal Marketing Order prices upon cooperative revenues may be calculated in a straightforward manner. By retracing the price effects of Federal Order policy changes in a stepwise manner, the impact on cooperative operations and revenues of these changes is approximated.

Carbocycle construction in terpenoid synthesis : subtitle the total synthesis of (±)-sarcodonin G and (±)-1-epi-9-norpresilphiperfolan-9-one
Creators: name: Gilbert, Michael W.
Publisher: name: University of British Columbia
Year: 2009

description: Carbocycle construction represents a significant challenge in synthetic studies geared towards terpenoid natural products. A step-wise annulation approach to the construction of the diterpenoid framework of the cyathanes (54) was investigated, ultimately leading to the first reported total synthesis of (±)-sarcodonin G (36). The sesquiterpenoid carbon skeleton of the presilphiperfolanes (270) was assembled via a tandem cyclization strategy, affording the known ketone, (±)-1-epi-9- norpresilphiperfolan-9-one (306). The construction of the cyathane 5-6-7 fused tricyclic framework commenced with 3-methyl-2-cyclohexen-1-one 38, representing the B-ring. The annulation sequences for A and C-rings utilized the bifunctional reagents 39 and 44, respectively. With the help of these reagents, the 5-6-6 fused tricycle 155 was quickly assembled from 38. Intermediate 155 was further elaborated, including a key SmI₂-mediated ring expansion, to afford the 5-6-7 fused tricycle 159, which displays the complete cyathane framework. The target structure, (±)-sarcodonin G (36), was obtained in several steps from 159. In addition, an advanced intermediate in the synthesis of 36 was transformed into substance 269, a likely synthetic precursor of the corresponding keto triol natural product, (±)-cyathin A₄ (37). Assembly of the presilphiperfolane 5-5-6 fused tricyclic carbon skeleton 270 was approached via a tandem cyclization strategy involving free-radical reactions. The key intermediates of this synthetic study, xanthates 367, were readily prepared from enone 49 in several steps. Bu₃SnH-mediated free-radical reaction of 367 yielded a mixture of cyclization products, alkenes 368, whose frameworks include the carbon skeleton of the natural product presilphiperfolan-9-ol (53). Alkenes 368 were subjected to oxidative cleavage conditions, affording the known ketone (±)-1-epi-9-norpresilphiperfolan-9-one (306). [diagram]

description: We study the effect of the FCNC mediated $Z$ boson in the rare semileptonic baryonic decays $Λ_b \to Λl^+ l^-$. We consider the model where the standard model fermion sector is extended by an extra vector like down quark, as a consequence of which it allows CP violating Z mediated flavor changing neutral current at the tree level. We find that due to this non-universal $Zbs $ coupling, branching ratios of the rare semileptonic $Λ_b$ decays are enhanced reasonably from their corresponding standard model values and the zero point of the forward backward asymmetry for $Λ_b \to Λμ^+ μ^-$ is shifted to the left.

description: The dramatic growth of research areas within the province of quantum state transmission (QST) is rapidly accelerating. An important insight to understand the process of QST can be fulfilled by considering the dynamical behavior of its entanglement content. One well-established approach to continuously transfer quantum states is utilizing spin structures. Here, from the view of entanglement propagation, we disclose the signature of fractional QST possibilities. In the present work, we proposed a form of spin-$\frac{1}{2}$ triangular plaquette whose Hamiltonian entails the spin-orbit coupling on the rungs and exchange interaction over the legs. The feature of such a system is that the time instants of QST emerge in a discrete fashion, thereby the values of exchange interactions associated with these moments behave fractionally. Importantly, it is found that for special values of magnetic interaction, QST has singularity i.e., the entanglement propagation is forbidden. In addition, the finite-size nature of this system makes it possible for us to read the nexus between time crystallinity and symmetry breaking. The development of our knowledge about time crystalline symmetry and its breaking helps us to understand the defined concept and fundamental physics of this phenomenon.

description: We study the macroscopic behavior of a stochastic spin ensemble driven by a discrete Markov jump process motivated by the Metropolis-Hastings algorithm where the proposal is made with spatially correlated (colored) noise, and hence fails to be symmetric. However, we demonstrate a scenario where the failure of proposal symmetry is a higher order effect. Hence, from these microscopic dynamics we derive as a limit as the proposal size goes to zero and the number of spins to infinity, a non-local stochastic version of the harmonic map heat flow (or overdamped Landau-Lipshitz equation). The equation is both mathematically well-posed and samples the canonical/Gibbs distribution related to the kinetic energy. The failure of proposal symmetry due to interaction between the confining geometry of the spin system and the colored noise is in contrast to the uncorrelated, white-noise, driven system. Specifically, the choice of projection of the noise to conserve the magnitude of the spins is crucial to maintaining the proper equilibrium distribution. Numerical simulations are included to verify convergence properties and demonstrate the dynamics.

description: It is proven that periodically varying and sign definite nonlinearity in a general case does not prevent collapse in two- and three-dimensional nonlinear Schrodinger equations: at any oscillation frequency of the nonlinearity blowing up solutions exist. Contrary to the results known for a sign alternating nonlinearity, increase of the frequency of oscillations accelerates collapse. The effect is discussed from the viewpoint of scaling arguments. For the three-dimensional case a sufficient condition for existence of collapse is rigorously established. The results are discussed in the context of the meanfield theory of Bose-Einstein condensates with time dependent scattering length.

description: We present a discrete stochastic model which represents many of the salient features of the biological process of wound healing. The model describes fronts of cells invading a wound. We have numerical results in one and two dimensions. In one dimension we can give analytic results for the front speed as a power series expansion in a parameter, p, that gives the relative size of proliferation and diffusion processes for the invading cells. In two dimensions the model becomes the Eden model for p near 1. In both one and two dimensions for small p, front propagation for this model should approach that of the Fisher-Kolmogorov equation. However, as in other cases, this discrete model approaches Fisher-Kolmogorov behavior slowly.

description: International trade occurs in physical space and moving goods requires time. This paper examines the importance of time as a trade barrier, estimates the magnitude of time costs, and relates these to patterns of trade and the international organization of production. Estimates indicate that each additional day spent in transport reduces the probability that the US will source from that country by 1 0- 1.5 percent. Conditional on exporting country, estimates directly identify a willingness-to-pay for time savings using variation across exporters and commodities in the relative price / speed tradeoff for air and ocean shipping. Each day saved in shipping time is worth 0.8 percent ad-valorem for manufactured goods. Relative declines over time in air shipping prices make time-savings less expensive, providing a compelling explanation for aggregate trade growth, compositional effects in trade growth, as well as growth in time-intensive forms of integration such as vertical specialization. Specifically, the advent of fast transport (air shipping and faster ocean vessels) is equivalent to reducing tariffs on manufactured goods from 32% to 9% between 1950-1998.

description: Low mass X-ray binaries are prime targets for continuous gravitational wave searches by ground-based interferometers. Results are presented from a search for five low-mass X-ray binaries whose spin frequencies and orbital elements are measured accurately from X-ray pulsations: HETE J1900.1-2455, IGR J00291+5934, SAX J1808.4-3658, XTE J0929-314, and XTE J1814-338. Data are analysed from Observing Run 2 of the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO). The search algorithm uses a hidden Markov model to track spin wandering, the $\mathcal{J}$-statistic maximum likelihood matched filter to track orbital phase, and a suite of five vetoes to reject artefacts from non-Gaussian noise. The search yields a number of low-significance, above threshold candidates consistent with the selected false-alarm probability. The candidates will be followed up in subsequent observing runs.

New antibiotics from a marine isolate of Bacillus laterosporus
Creators: name: Barsby, Todd
Publisher: name: University of British Columbia

description: The continued chemical investigation of a marine isolate of Bacillus laterosporus has resulted in the discovery of nine new metabolites, seven of which displayed antibiotic activity. The bogorols A - E (26-30) were found to comprise a novel structural template of the cationic peptide class of antibiotics, while the basiliskamides A and B (50 and 51) were discovered to possess potent antifungal activity versus both Candida albicans and Aspergillus fumigatus. Two structurally novel acyldipeptides, tupuseleiamides A and B (55 and 56), were the result of a serendipitous discovery. The structures in this thesis were elucidated using a combination of NMR spectroscopy, mass spectrometry, and chemical degradation coupled with chiral GC analyses. The fragmentation pattern observed in the mass spectrum of 26 allowed for the rapid structure elucidation of 27-30. An empirical method based on steric and electronic arguments was used in conjunction with a series of partial acid hydrolyses to rationalize the relative placement of the enantiomeric pairs of amino acids within the constitution of 26. A series of common structural features defined the novel bogorol cationic peptide template. The C and N termini of the linear peptides were found to be capped by an amino alcohol and an α-hydroxy acid, respectively, leaving the cationic residues to reside solely in the interior of the peptide. In addition, the bogorols contained the uncommon amino acid, E-2-amino-2-butenoic acid. A preliminary investigation of the secondary structure of the bogorols revealed their propensity to exist as ahelices, thus allowing 26-30 to adopt the amphipathic structure characteristic of cationic peptide antibiotics. The bogorols were found to exhibit in vitro antimicrobial activity versus methicillin resistant Staphylococcus aureus and vancomycin resistant Enterococcus spp. comparable to that found with other cationic peptide antibiotics. Finally, progress was made towards the total synthesis of 26. The de novo biosynthesis of 2,6-dimethyl-5-heptenal (60) by the dendronotid nudibranch, Melibe leonina, was investigated using a stable isotope incorporation experiment with [l,2-¹³C₂]acetate. This study represents the first demonstration of de novo terpene biosynthesis by a dendronotid nudibranch. As well, it is the first example to show that nudibranchs are capable of de novo monoterpene biosynthesis. The work reported with M. leonina supports recent evolutionary theory with regards to nudibranch de novo biosynthesis.

description: We demonstrate that the transition photon radiation and pair creation can be interpreted as a diffractive phenomenon in terms of the light-cone wave functions in a way similar to the Good-Walker approach [6] to the diffraction dissociation. Our formulas for spectra agree with those obtained by Baier and Katkov [5] within the quasiclassical operator method. However, there is some disagreement with earlier results by Garibyan [4].

Food Consumption/Nutrition/Food Safety

description: Computable General Equilibrium (CGE) models are increasingly being used to project world food markets in order to support forward-looking policy analysis. Such projections hinge critically on the underlying functional form for representing consumer demand. Simple functional forms can lead to unrealistic projections by failing to capture changes in income elasticities of demand. We adopt as our benchmark the recently introduced AIDADS demand system and compare it with several alternative demand systems currently in widespread use in CGE models. This comparison is conducted in the context of projections for disaggregated global food demand using a global CGE model. We find that AIDADS represents a substantial improvement, particularly for the rapidly growing developing countries. For these economies, the most widely used demand systems tend to over-predict future food demands, and hence overestimate future production and import requirements for agricultural products.

description: The secular behavior of an orbit under the gravitational perturbation due to a two-dimensional uniform disk is studied in this paper, through analytical and numerical approaches. We develop the secular approximation of this problem and obtain the averaged Hamiltonian for this system first. We find that, when the ratio of the semimajor axes of the inner orbit and the disk radius takes very small values ($\ll1$), and if the inclination between the inner orbit and the disk is greater than the critical value of $30^\circ$, the inner orbit will undergo the (classical) Lidov-Kozai resonance in which variations of eccentricity and inclination are usually very large and the system has two equilibrium points at $ω=π/2,3π/2$ ($ω$ is the argument of perihelion). The critical value will slightly drop to about $27^\circ$ as the ratio increases to 0.4. However, the secular resonances will not occur for the outer orbit and the variations of the eccentricity and inclination are small. When the ratio of the orbit and the disk radius is nearly $1$, there are many more complicated Lidov-Kozai resonance types which lead to the orbital behaviors that are different from the classical Lidov-Kozai case. In these resonances, the system has more equilibrium points which could appear at $ω=0,π/2,π,3π/2$, and even other values of $ω$. The variations of eccentricity and inclination become relatively moderate, moreover, in some cases the orbit can be maintained at a highly inclined state. In addition, a analysis shows that a Kuzmin disk can also lead to the (classical) Lidov-Kozai resonance and the critical inclination is also $30^\circ$.

description: We apply an improved Taylor expansion method, which is a variational scheme to the Ising model in two dimensions. This method enables us to evaluate the free energy and magnetization in strong coupling regions from the weak coupling expansion, even in the case of a phase transition. We determine the approximate value of the transition point using this scheme. In the presence of an external magnetic field, we find both stable and metastable physical states.

description: The purpose of this study is to describe the management style, performance appraisal and employee development of selected personnel from an academic institution in Central Luzon, Philippines. The study used a descriptive-correlation research design with survey as the primary instrument for data gathering. 75 personnel took part in the survey with the use of convenience sampling technique. The researchers used an adapted and modified instrument to gather data. The instrument underwent a reliability test and generated an overall coefficient of .925. This study used SPSS 20 to analyze the data. The study found that the personnel agreed on the context of management style in the organization. They also shared the same response on how their performance appraisal works and how the organization plans for employee development. There is also a significant difference in performance appraisal and employee development when grouped according to years in service and employment status. In terms of relationship, there is a low-moderate positive relationship between management style, performance appraisal and employee development. Based on the results of the study, the researchers presented some general recommendations for human resource management and for the institutions.

International Relations/Trade

description: The making of projections often requires an economy-wide perspective, and the estimation of consumer demands at the international level. In this paper, an implicit, directly additive demand system (AIDADS) is estimated using cross-country data on consumer expenditures from the International Comparison Program (ICP), and then from Global Trade Analysis Project (GTAP) data. The two data sets are found to produce results that are quite consistent despite their differing origins, and the fact that the former is based on consumer goods that embody wholesale/retail margins, while margin demands are treated separately in GTAP. Given the similarity of the results, the estimation based on GTAP data is favored because it is readily matched to input-output based production and trade data, and provides valuable new information concerning how aggregate margin expenditures are related to per capita income.

description: This paper examines necessary and sufficient conditions for the uniqueness of dynamic Groves mechanisms when the domain of valuations is restricted. Our approach is to appropriately define the total valuation function, which is the expected discounted sum of each period's valuation function from the allocation and thus a dynamic counterpart of the static valuation function, and then to port the results for static Groves mechanisms to the dynamic setting.
