description: Boundary conditions play a non trivial role in string theory. For instance the rich structure of D-branes is generated by choosing appropriate combinations of Dirichlet and Neumann boundary conditions. Furthermore, when an antisymmetric background is present at the string end-points (corresponding to mixed boundary conditions) space time becomes non-commutative there. We show here how to build up normal ordered products for bosonic string position operators that satisfy both equations of motion and open string boundary conditions at quantum level. We also calculate the equal time commutator of these normal ordered products in the presence of antisymmetric tensor background.

description: Consumer acceptance and willingness to pay for three nonconventional attributes associated with six processed blueberry products was examined through an in-store conjoint experiment survey. Both credence and experience attributes were considered, including whether the products were produced locally, and whether they were organic or sugar-free. The results indicate heterogeneity in consumer preference and willingness to pay for different attributes across product categories. Local products and organic formulations generally received positive willingness to pay across all products. This information has implications for blueberry growers and retailers who are trying to create and position value-added products for maximum revenue.

description: We consider the problem of estimating the ensemble average of an observable on an ensemble of equally prepared identical quantum systems. We show that, among all kinds of measurements performed jointly on the copies, the optimal unbiased estimation is achieved by the usual procedure that consists in performing independent measurements of the observable on each system and averaging the measurement outcomes.

description: The effect of stochastic factors on soil carbon makes the quantity of carbon generated under a sequestration project uncertain. Hence, the quantity of sequestered carbon may need to be discounted to avoid liability from shortfalls. We present a potentially applicable uncertainty discount and discuss difficulties that might arise in empirical use. We insist that the variance in historical crop yields across geographical areas is used to derive a proxy variance for forming an uncertainty discount for carbon projects. Application of our approach suggests that project level uncertainty discounts would be 15–20% for the East Texas region.

Impact of hunting on snowshoe hare populations in Newfoundland
Creators: name: Joyce, Tammy Lee
Publisher: name: University of British Columbia
Year: 2009

description: Snowshoe hares were introduced to Newfoundland between 1864 and 1876 to provide food and hunting opportunities. At that time, Newfoundland, an island, had no small game species. Today, snowshoe hares are still mainly hunted for food, particularly in rural areas. Harvest management for snowshoe hare has changed very little in Newfoundland since it started in 1879, with unlimited harvest allowed from October to February each year. Snowshoe hares were in low numbers in Newfoundland from 1979 to 1995, and many hunters believed that the unlimited harvest was depleting the hare populations. Monitoring the effects of harvesting on snowshoe hare abundance is an arduous task, requiring monitoring effort throughout an entire hare cycle. I developed a modified, Lotka-Volterra predator-prey model to help with this task. Model parameter values were taken from the Kluane Boreal Forest Ecosystem Study. Harvesting applied to the model was derived from Newfoundland harvest statistics for 1965 to 1999. Harvesting lengthened the cycle period, which was directly related to the proportion of the population harvested at a cyclic low. Model parameters were tested for sensitivity. Changes to snowshoe hare abundance within a hunting season were monitored using mark-recapture techniques. I live-trapped hares through a hunting season on two control (non-hunted) and two hunted grids from September 1999 to March 2000 during a cyclic peak. Population estimates were calculated using a Jackknife estimator (CAPTURE). Substantial declines were seen between September and January in both hunted areas, 46% and 77% of the fall populations, while the control areas remained stable at 91% and 98%. There was some recovery in the population following the end of harvesting that is unlikely to be due to immigration. Abrams' (1993) theory of adaptive antipredator behavior was discussed. Both hunted populations recovered from harvesting by the following fall. Declines in population estimates of September 2001 compared to September 2000 indicated that the population was entering a cyclic decline. Population estimates based on fecal pellet counts can be used as a cheaper alternative to live-trapping for monitoring snowshoe hare populations. For pellet counts in the Newfoundland forest, I found that the most efficient plot shape of those tested was a 10x150 cm rectangle. Pellets remained intact for at least 1 year but disappeared into the moss when it was the main ground cover. Management of snowshoe hares should include a regular monitoring program through extensive fecal pellet counts that have been calibrated to live trapping efforts. At times of population lows in the snowshoe hare cycle, harvesting should be reduced.

description: The string theory calculation of the 1/2-BPS circular Wilson loop of N=4 SYM in the planar limit at next to leading order at strong coupling is revisited in the ratio of its semiclassical string partition function and the one dual to a latitude Wilson loop with trivial expectation value. After applying a conformal transformation from the disk to the cylinder, this problem can be approached by means of the Gel'fand-Yaglom formalism. Using results from the literature and the exclusion of zero modes from a modified Gel'fand-Yaglom formula, we obtain matching with the known field theory result. As seen in the phaseshift method computation, non-zero mode contributions cancel and the end result comes from the zero mode degeneracies of the latitude Wilson loop.

description: The Quasi-Elastic (QE) contribution of the nuclear inclusive electron scattering model developed in Nucl. Phys. A627 (1997) 543 is extended to the study of electroweak Charged Current (CC) induced nuclear reactions, at intermediate energies of interest for future neutrino oscillation experiments. The model accounts for, among other nuclear effects, long range nuclear (RPA) correlations, Final State Interaction (FSI) and Coulomb corrections. Predictions for the inclusive muon capture in $^{12}$C and the reaction $^{12}$C $(ν_μ,μ^-)X$ near threshold are also given. RPA correlations are shown to play a crucial role and their inclusion leads to one of the best existing simultaneous description of both processes, with accuracies of the order of 10-15% per cent for the muon capture rate and even better for the LSND measurement.

Demand and Price Analysis
Food Consumption/Nutrition/Food Safety

description: There is evidence that consumers are increasingly purchasing food directly from local producers, but little is understood about which market-specific, intrinsic, extrinsic, and demographic attributes influence the probability of preferring to purchase fresh produce through direct-market channels. A multinomial logit model is used to analyze a national dataset of fresh produce consumers with a focus on exploring differences among those that prefer to purchase direct always, occasionally (seasonally and as a secondary source), and never. Results suggest that to increase patronage and loyalty of current customers, producers may emphasize the availability of fresh, superior, vitamin-rich, and locally-grown produce at market locations through booth displays, ads in magazines, radio spots, and electronic newsletters. To attract new customers who do not currently admit a preference for purchasing direct, producers may find greater success by locating in convenient-to-reach venues, showcasing a variety of colorful offerings, and working to enhance the overall aesthetic appeal of market locations.

description: The appearance of organic produce is often less than perfect because of limited methods of avoiding plant diseases. We combine hypothetical and real auction mechanisms to investigate how cosmetic damage affects consumers’ willingness to pay for apples. We find that 75% of the participants are willing to pay more for organic than for conventional apples given identical appearance. However, at the first sight of any imperfection in the appearance of the organic apples, this segment is significantly reduced. Furthermore, the cosmetic damage has a larger impact on the willingness to pay for organic apples than for conventional apples.
Acoustic scattering by periodic arrays of air-bubbles

description: This paper considers acoustic scattering by and propagation through line and plane arrays of air-bubbles in liquid media. The self-consistent method is used to derive the effective scattering function of a single bubble embedded in the arrays, incorporating all multiple scattering processes. For the line case, an exact result is derived. In the plane array situation, only an approximate analytic result is possible. Numerical computations have been carried out to show the multiple scattering effects on wave scattering. It is shown that depending on the distance between bubbles the resonance peak of a single bubble can either be broadened or narrowed due to multiple scattering and it shows an oscillatory behavior as the distance changes. Meanwhile, the peak scattering amplitude is also be either enhanced or reduced. The previously predicted strong enhancement, however, is not evident. For plane arrays, the usual resonant scattering of a single bubble in absence of other bubbles can be suppressed by multiple scattering when the distance between bubbles is sufficiently small. As the distance increases, the resonant scattering starts to appear, and the resonance peak position is alternately shifted towards higher and lower values. Moreover, it is predicted that wave propagation through a plane bubble array can be significantly inhibited in a range of frequencies slightly higher than the natural frequency of a single bubble, possibly a useful feature for noise screening. The ambiguities in the previous results are pointed out.

Bornean whiskered myotis
 New record
New to Sumatra. Lampung Province: Way Canguk Forest.
 Remarks
 This is a medium-large brown Myotis species (FA = 45.8 mm) with wing membrane attached to the base of the toes. One adult male was collected by previous researchers from Gimbar 2 cave in Way Canguk Forest (MZB 35012). Comparing with known species on the Sunda Shelf, this bat most likely belongs to the montivagus species complex, which has not been recorded yet in Sumatra. Based on differences in forearm length and craniodental characters, Görföl et al. (2013) recognized four species in the montivagus species complex from Asia, including M. borneoensis, M. federatus, M. montivagus, and M. peytoni. Only M. borneoensis (Borneo) and M. federatus (Peninsular Malaysia) were reported from the Sunda Shelf, with M. montivagus known from South China and North Myanmar, and M. peytoni from India (Görföl et al., 2013). Our sample exhibits characteristics of each species except M. federatus, but we tentatively assign it to M. borneoensis based on cranial characters (separation between P 2 and P 4 and the length of the anteorbital bridge) and distribution. Further comparison and molecular analyses are necessary to clarify the taxonomic status of this species. In our study area, it can be easily identified from other known Myotis species by its larger forearm length.

description: Recent consolidation in agriculture has shifted production toward fewer but larger farms, reshaping business relationships between farmers, processors, input suppliers, and local communities. We analyze growth and diversification of U.S. corn, wheat, apple, and beef farms by examining longitudinal changes in 10 size cohorts through three successive censuses. We fail to reject Gibrat’s law in apple and wheat industries and the mean reversion hypothesis in beef and corn industries. Apple and wheat farms diversify over time. The findings suggest that scale economies diminish for large farms across all four industries and scope economies dominate scale economies for large apple and wheat farms.

description: Additional file 1: Fig. S1. Sample skull model with measurements applied. Cranium length was measured from the tip of the premaxillary bone to the base of the quadrate bone. Each maxillary tooth was measured from the point of contact with the maxillary bone to the apical-most point (TL). All measurements were repeated three times each and the average value was used for subsequent analyses. Fig. S2. Ancestral state reconstruction of maxillary tooth phenotype in which fang phenotypes were coded as one of three states: unmodified, grooved, or hollow. We used the ‘ancthresh’ function in phytools which implements Bayesian MCMC to estimate ancestral states for discrete characters under the threshold model from quantitative genetics (100,000 generations, 20,000 burn-in generations). Fig. S3. The same analysis as S2 (‘ancthresh’ Bayesian MCMC estimation of ancestral states, 100,000 generations, 20,000 burn-in generations) was run with four possible fang states: unmodified, grooved, hollow (elapids, some lamprophiids), or tubular (vipers). Results between these two models (S2 and S3) are highly consistent, and both show likely reversals from the grooved state to the unmodified state (Hydrodynastes gigas; Gomesophis brasiliensis and Helicops angulatus; Conopsis nasus), though the posterior probability of fang loss in the NE/NV colubriform is higher in the three-state model. Whether front fangs are grouped into a single category, or treated as unique character states, it appears likely that rear fangs have been lost in NE/NV colubriforms on more than one occasion. Fig. S4. We reconstructed ancestral character states under a maximum likelihood framework using the ‘ace’ function in the R package ‘ape.’ For discrete characters, the likelihood values of a given node are calculated from the tip states of descendent lineages. We specified an equal rates model, in which transitions among all possible character states occur at the same rate. Here the results are shown for a scenario in which we classified fangs in 3 states (unmodified, grooved, hollow), as in S. Figure 2. Fig. S5. The same analysis as S4 is shown here for a four-state characterization of fangs. Results of all four models (S2-S5) for the nodes of interest are highly congruent (see main text). The main difference between ancThresh and ace outputs are that likelihood-based analyses (ace, S4 and S5) do not support the notion that the colubriform common ancestor possessed grooved fangs, based on our sampling.

description: Federated Learning (FL) enables a large number of users to jointly learn a shared machine learning (ML) model, coordinated by a centralized server, where the data is distributed across multiple devices. This approach enables the server or users to train and learn an ML model using gradient descent, while keeping all the training data on users' devices. We consider training an ML model over a mobile network where user dropout is a common phenomenon. Although federated learning was aimed at reducing data privacy risks, the ML model privacy has not received much attention. In this work, we present PrivFL, a privacy-preserving system for training (predictive) linear and logistic regression models and oblivious predictions in the federated setting, while guaranteeing data and model privacy as well as ensuring robustness to users dropping out in the network. We design two privacy-preserving protocols for training linear and logistic regression models based on an additive homomorphic encryption (HE) scheme and an aggregation protocol. Exploiting the training algorithm of federated learning, at the core of our training protocols is a secure multiparty global gradient computation on alive users' data. We analyze the security of our training protocols against semi-honest adversaries. As long as the aggregation protocol is secure under the aggregation privacy game and the additive HE scheme is semantically secure, PrivFL guarantees the users' data privacy against the server, and the server's regression model privacy against the users. We demonstrate the performance of PrivFL on real-world datasets and show its applicability in the federated learning system.

description: A model is constructed for the confinement of test particles moving on a brane. Within the classical framework of this theory, confining a test particle to the brane eliminates the effects of extra dimensions, rendering them undetectable. However, in the quantized version of the theory, the effects of the gauge fields and extrinsic curvature are pronounced and this might provide a hint for detecting them. As a consequence of confinement the mass of the test particle is shown to be quantized. The condition of stability against small perturbations along extra dimensions is also studied and its relation to dark matter is discussed.

description: Earthquake fault zones are more complex, both geometrically and rheologically, than an idealised infinitely thin plane embedded in linear elastic material. To incorporate nonlinear material behaviour, natural complexities, and multi-physics coupling within and outside of fault zones, here we present a first-order hyperbolic and thermodynamically compatible mathematical model for a continuum in a gravitational field which provides a unified description of nonlinear elasto-plasticity, material damage and of viscous Newtonian flows with phase transition between solid and liquid phases. The fault geometry and secondary cracks are described via a scalar function $ξ\in [0,1]$ that indicates the local level of material damage. The model also permits the representation of arbitrarily complex geometries via a diffuse interface approach based on the solid volume fraction function $α\in [0,1]$. Neither of the two scalar fields $ξ$ and $α$ needs to be mesh-aligned, allowing thus faults and cracks with complex topology and the use of adaptive Cartesian meshes (AMR). The model shares common features with phase-field approaches but substantially extends them. We show a wide range of numerical applications that are relevant for dynamic earthquake rupture in fault zones, including the co-seismic generation of secondary off-fault shear cracks, tensile rock fracture in the Brazilian disc test, as well as a natural convection problem in molten rock-like material.

Die Studie zeigt am Beispiel Südamerikas auf, welche Faktoren die Wirksamkeit künstlerischer Projekte im Ausland auch angesichts fortschreitender Globalisierung, lokaler Transformationsprozesse und neuer Informationstechnologien im Sinne einer nachhaltigen Kulturpolitik befördern können.
 Dazu wurden Experten aus Argentinien, Chile, Peru und Europa über ihre Erfahrungen mit künstlerischem Austausch befragt. Zudem wurden exemplarisch drei Tourneeausstellungen des Instituts für Auslandsbeziehungen (ifa) anhand ihrer Berichtsbögen aus Buenos Aires, Santiago de Chile und Lima ausgewertet. Zum Vergleich wurden außerdem innovative Projekte aus Großbritannien, der Schweiz und Spanien vorgestellt.
 Es zeigte sich, dass Tourneeausstellungen, die Originalkunstwerke zeitgenössischer Kunst aus Deutschland präsentieren, im Ausland sehr willkommen sind. Deren Vermittlung könnte aber in Kooperation mit den lokalen Partnern noch verbessert werden. Zusätzlich wurden von den Interviewpartnern diskursivere Formate unter Einbeziehung lokaler (künstlerischer) Szenen und Themen gefordert. Aus diesem Grund sollten auch unabhängige Kunsträume als Kooperationspartner einer AKBP berücksichtigt werden. Durch die Zusammenarbeit mit Beratern vor Ort sowie den direkten Kontakt zu den Gastinstitutionen würde die Anbindung an vorhandene Zusammenhänge noch wirksamer.
 Die Einrichtung einer Datenbank, die das weltweite Netzwerk von Institutionen, unabhängigen Kunsträumen, Akteuren und Künstlern abbildet, könnte bei der Planung zukünftiger künstlerischer Projekte behilflich sein und eine spätere Evaluierung erleichtern.

description: Hurricanes have caused substantial damage in parts of the U.S. Damages are increasing, perhaps as part of a natural cycle or perhaps in part related to global warming. This paper examines the economic damages that hurricanes cause to U.S. agriculture, estimates the increased damage from an increase in hurricane frequency/intensity, and examines the way that sectoral reactions reduce damages. The simulation results show that hurricanes and associated adjustments cause widespread damage and redistribute agricultural welfare. We find that crop mix shifts of vulnerable crops from stricken to nonstricken regions significantly mitigate hurricane damages.

Effects of dietary mg status and susceptibility to hypertension on in-vitro lipid peroxidation in rats
Creators: name: Lai, Lucinda Man Lai
Publisher: name: University of British Columbia
Year: 2009

description: This study was designed to determine the association between dietary Mg (Mg) status on induction of hypertension in both normotensive Wistar-Kyoto rats (WKY) and spontaneously hypertensive rats (SHR). The particular interest was the link between lipoprotein lipid composition and susceptibility to oxidation and development of hypertension caused by Mg status. Six-week old male SHR and WKY were fed a synthetic diet with varying Mg levels (Mgreplete and deplete) for eight weeks. Two experiments were conducted with animals fed either casein (Experiment I) or soy (Experiment II) protein diets. SHR exhibited significantly (P<0.05) lower plasma cholesterol, triglyceride and phospholipid concentrations than WKY rats, regardless of dietary protein source. In Experiment I, Mg deficiency in casein fed rats significantly (P<0.05) increased plasma and lipoproteins (VLDL and LDL) cholesterol concentrations in both WKY and SHR strains. These results indicated that Mg deficiency significantly (P<0.05) increased plasma and lipoprotein cholesterol concentrations in a similar way in both WKY and SHR rats, regardless of differences in lipid metabolism between these two inbred strains of rats. In Experiment II, the hypercholesterolemic effect of Mg deficiency was diminished when rats were fed a soy-protein diet. Mg deficiency significantly increased plasma cholesterol concentrations only in SHR rats, but not in WKY rats. Lipoproteins isolated from SHR produced less TBARs and fluorescence after 180-min Cu -induced forced peroxidation, and, thereby, were less susceptible to lipid peroxidation, than those isolated from WKY. SHR exhibited significantly (P<0.05) higher systolic blood pressure than WKY rats, and rats fed the Mg-deficient diet showed significantly (P<0.05) higher systolic blood pressure than counterparts fed the Mg-replete diet in both Experiments I and II. Mg deficiency also significantly (P<0.05) enhanced the genetic predisposition of the SHR to hypertension, regardless of dietary protein source. It can be concluded from the present study that greater systolic blood pressure observed in Mg-deficient rats was in agreement with an increased lipoprotein susceptibility to forced peroxidation.

description: The formation of supermassive stars has generally been studied under the assumption of rapid accretion of pristine metal-free gas. Recently it was found, however, that gas enriched to metallicities up to $Z \sim 10^{-3}$ Z$_{\odot}$ can also facilitate supermassive star formation, as long as the total mass infall rate onto the protostar remains sufficiently high. We extend the analysis further by examining how the abundance of supermassive star candidate haloes would be affected if all haloes with super-critical infall rates, regardless of metallicity were included. We investigate this scenario by identifying all atomic cooling haloes in the Renaissance simulations with central mass infall rates exceeding a fixed threshold. We find that among these haloes with central mass infall rates above 0.1 M$_{\odot}$ yr$^{-1}$ approximately two-thirds of these haloes have metallicities of $Z > 10^{-3}$ Z$_{\odot}$. If metal mixing within these haloes is inefficient early in their assembly and pockets of metal-poor gas can remain then the number of haloes hosting supermassive stars can be increased by at least a factor of four. Additionally the centres of these high infall-rate haloes provide ideal environments in which to grow pre-existing black holes. Further research into the (supermassive) star formation dynamics of rapidly collapsing haloes, with inhomogeneous metal distributions, is required to gain more insight into both supermassive star formation in early galaxies as well as early black hole growth.

Horsfield’s myotis
 New records
New to Sumatra; Lampung Province: Way Canguk Forest.
 New material
Three individuals were collected as voucher specimens. Lampung Province: Way Canguk Forest, 1♂, 2♀♀ (MZB 35750–35752).
 Remarks
 It is a medium grayish-brown Myotis species (FA = 36.4–40.2 mm, n = 6) with wing membrane attached to the fifth metatarsal about 2 mm from the ankle. P 3 is completely inline with or partially lingual to the toothrow. The crown areas of P 3 and P 3 are one-third to two-thirds that of P 2 and the first lower premolar (P 2), respectively. Three individuals were captured flying low over a slow-moving section of the Way Canguk River. Additional records from Gimbar 2 cave in Way Canguk Forest were in the MZB (MZB 31484, 35013, 35014). In the study area, it can be distinguished from other known Myotis species by the wing attachment position. Comparing with all known Myotis species of the Sunda Shelf, the body size, wing attachment point, and dental characteristics are most comparable to that of M. horsfieldii (Bates and Harrison, 1997; Kingston et al., 2006), which has not been yet recorded from Sumatra (Simmons, 2005).

description: The behavior of agricultural commodity markets can arguably result in markedly asymmetric price cycles, that is, downward cycles of substantially different length and breadth than upward cycles. This study assesses whether asymmetric-cycle models can enhance the understanding of the dynamics and provide for a better forecasting of U.S. soybeans and Brazilian coffee prices. The forecasts from asymmetric cycle models are found to be substantially mode precise than those obtained from standard autoregressive models. The asymmetric cycle models also provide useful insights on the markedly different dynamics of the upward versus the downward cycles exhibited by the prices of these two commodities.

description: Cattle feeding enterprises operate amid variability originating in prices and production. This research explicitly models yield risks related to cattle feeding by relating the mean and variance of yield performance factors to observable conditioning variables. The results demonstrate that pen characteristics, such as entry weight, gender, placement season, and location influence the mean and variability of yield factors, defined as dry matter feed conversion, average daily gain, mortality, and animal health costs. Ex ante profit distributions, conditional on cattle placement characteristics, are derived through simulation methods to evaluate the effects of price or yield shocks on the distributional characteristics of expected profits.

description: Although culture is still a field of competence for each Member State, the EU is active in the area of European external cultural relations and complements the activities of Member States whenever it is necessary and appropriate. The study forms part of a reflection on the future actions of the European Union (EU) in the field of external cultural relations. It takes stock of the main EU mechanisms for supporting European external cultural relations since 2007 in order to ascertain which policy areas are involved in funding culture and the kinds of projects and actors that receive funding. Furthermore the paper looks at the shortcomings of current EU funding possibilities and proposes some alternative models of cooperation and funding, which have been developed by other actors in the area of European external cultural relations.

description: Many social networks have the following properties: (i) a short average distance between any two individuals; (ii) a high clustering coefficient; (iii) segregation patterns; the presence of (iv) brokers and (v) hubs. (i) and (ii) define a small world network. This paper develops a strategic network formation model where agents have heterogeneous knowledge of the network: cognizant agents know the whole network, while ignorant ones are less knowledgeable. For a broad range of parameters, all pairwise Nash (PN) networks have properties (i)-(iv). There are some PN networks with one hub. Cognizant agents have higher betweenness centrality: they are the brokers who connect different parts of the network. Ignorant agents cause the emergence of segregation patterns. The results are robust to varying the number of cognizant agents and to increasing the knowledge level of ignorant ones. An application shows the relevance of the results to assessing the welfare impact of an increase in network knowledge due to, e.g., improved access to social networking tools.
