description: Detections of massive stars in the direction of the H II region CS 78 in NGC 6334 and of G332.809-0.132 are here presented. The region covered by the G332.809-0.132 complex coincides with the RCW 103 stellar association. In its core (40' in radius), approximately 110 OB candidate stars (Ks < 10 mag and 0.4 < AKs < 1.6 mag) were identified using 2MASS, DENIS, and GLIMPSE data. This number of OB stars accounts for more than 50% of the observed number of Lyman continuum photons from this region. Medium-resolution K-band spectra were obtained for seven early types, including one WN 8 star and one Ofpe/WN 9 star; the latter is located near the RCW 103 remnant and its luminosity is consistent with a distance of about 3 kpc. The area analyzed encloses 9 of the 34 OB stars previously known in RCW 103, as well as IRAS 16115-5044, which we reclassify as a candidate luminous blue variable. The line of sight is particularly interesting, crossing three spiral arms; a molecular cloud at -50 (with RCW 103 in the Scutum-Crux arm) and another at -90 km s-1 (in the Norma arm) are detected, both rich in massive stars and supernova remnants. We also report the detection of a B supergiant as the main ionizing source of CS 78, 2MASS J17213513-3532415. Medium-resolution H and K band spectra display H I and He I lines, as well as Fe II lines. By assuming a distance of 1.35 kpc, we estimate a bolometric magnitude of -6.16, which is typical of supergiants.

description: Recent papers by Fewster and Roman have emphasized that wormholes supported by arbitrarily small amounts of exotic matter will have to be incredibly fine-tuned if they are to be traversable. This paper discusses a wormhole model that strikes a balance between two conflicting requirements, reducing the amount of exotic matter and fine-tuning the metric coefficients, ultimately resulting in an engineering challenge: one requirement can only be met at the expense of the other. The wormhole model is macroscopic and satisfies various traversability criteria.

Numerical simulations of an effective two-dimensional model for flows with a transverse magnetic field

description: This paper presents simulations of the 2d model developed by Pothérat at al (\emph{J. Fluid Mech}, 2000) for MHD flows between two planes with a strong transverse homogeneous and steady magnetic field, accounting for moderate inertial effects in Hartmann layers. We first show analytically how the additional terms in the equations of motion accounting for inertia, soften velocity gradients in the horizontal plane, and then we implement the model on a code to carry out numerical simulations to be compared with available experimental results. This comparison shows that the new model can give very accurate results as long as the Hartmann layer remains laminar. Both experimental velocity profiles and global angular momentum measurements are closely recovered, and local and global Ekman recirculations are shown to alter significantly the aspect of the flow as well as the global dissipation.

description: We provide a lower bound for the coherence of the homotopy commutativity of the Brown-Peterson spectrum, BP, at a given prime p and prove that it is at least (2p^2 + 2p - 2)-homotopy commutative. We give a proof based on Dyer-Lashof operations that BP cannot be a Thom spectrum associated to n-fold loop maps to BSF for n=4 at 2 and n=2p+4 at odd primes. Other examples where we obtain estimates for coherence are the Johnson-Wilson spectra, localized away from the maximal ideal and unlocalized. We close with a negative result on Morava-K-theory.

description: The movement of motor particles consisting of one or several molecular motors bound to a cargo particle is studied theoretically. The particles move on patterns of immobilized filaments. Several patterns are described for which the motor particles undergo non-directed but enhanced diffusion. Depending on the walking distance of the particles and the mesh size of the patterns, the active diffusion coefficient exhibits three different regimes. For micrometer-sized motor particles in water, e.g., this diffusion coefficient can be enhanced by two orders of magnitude.

description: Cascading failure is a potentially devastating process that spreads on real-world complex networks and can impact the integrity of wide-ranging infrastructures, natural systems, and societal cohesiveness. One of the essential features that create complex network vulnerability to failure propagation is the dependency among their components, exposing entire systems to significant risks from destabilizing hazards such as human attacks, natural disasters or internal breakdowns. Developing realistic models for cascading failures as well as strategies to halt and mitigate the failure propagation can point to new approaches to restoring and strengthening real-world networks. In this review, we summarize recent progress on models developed based on physics and complex network science to understand the mechanisms, dynamics and overall impact of cascading failures. We present models for cascading failures in single networks and interdependent networks and explain how different dynamic propagation mechanisms can lead to an abrupt collapse and a rich dynamic behavior. Finally, we close the review with novel emerging strategies for containing cascades of failures and discuss open questions that remain to be addressed.

description: We have carried out an extensive observational study (from BIMA data) and made a preliminary theoretical investigation of the molecular gas around HH2. The molecular maps show a very complex morphological, kinematical and chemical structure. The overall main conclusion of this work confirms the findings of Paper I and II, by demonstrating that in addition to the strong photochemical effects caused by penetration of the UV photons from HH2 into molecular cloud, a range of complex radiative and dynamical interactions occur. Thus, despite the apparent `quiescent' nature of the molecular cloud ahead of HH2, the kinematical properties observed within the field of view suggest that it is possibly being driven out by powerful winds from the VLA 1 protostar.

description: Model description of patterns of atomic displacements in twisted bilayer systems has been proposed. The model is based on the consideration of several dislocation ensembles, employing a language that is widely used for grain boundaries and film/substrate systems. We show that three ensembles of parallel screw dislocations are sufficient both to describe the rotation of the layers as a whole, and for the vortex-like displacements resulting from elastic relaxation. The results give a clear explanation of the observed features of the structural state such as vortices, accompanied by alternating stacking.

description: Organic semiconductors are a promising platform for ambient polaritonics. Several applications, such as polariton routers, and many-body condensed matter phenomena are currently hindered due to the ultra-short polariton lifetimes in organics. Here, we employ a single-shot dispersion imaging technique, using 4 nanosecond long non-resonant excitation pulses, to study polariton lasing in a $λ/2$ planar organic microcavity filled with BODIPY-Br dye molecules. At a power threshold density of $1.5 MW/cm^{2}$, we observe the transition to a quasi-steady state, 1.2 ns long-lived, single-mode polariton lasing and the concomitant superlinear increase of photoluminescence, spectral line-narrowing, and energy blueshift

description: By reformulating the first law of thermodynamics in the fashion of quantum-mechanical operators on the parameter manifold, we propose a universal class of quantum heat engines (QHE) using the multi-level quantum system as the working substance. We obtain a general expression of work for the thermodynamic cycle with two thermodynamic adiabatic processes, which are microscopically quantum adiabatic processes. We also classify the conditions for a 3-level QHE to extract positive work from a heat bath. Our result is counter-intuitively different from that of a 2-level system. As a more realistic illustration, a 3-level atom system with dark state configuration manipulated by classical light is used to demonstrate our central idea.

description: Numerous car accidents are caused by improper driving maneuvers. Serious injuries are however avoidable if such driving maneuvers are detected beforehand and the driver is assisted accordingly. In fact, various recent research has focused on the automated prediction of driving maneuver based on hand-crafted features extracted mainly from in-cabin driver videos. Since the outside view from the traffic scene may also contain informative features for driving maneuver prediction, we present a framework for the detection of the drivers' intention based on both in-cabin and traffic scene videos. More specifically, we (1) propose a Convolutional-LSTM (ConvLSTM)-based auto-encoder to extract motion features from the out-cabin traffic, (2) train a classifier which considers motions from both in- and outside of the cabin jointly for maneuver intention anticipation, (3) experimentally prove that the in- and outside image features have complementary information. Our evaluation based on the publicly available dataset Brain4cars shows that our framework achieves a prediction with the accuracy of 83.98% and F1-score of 84.3%.

description: Integrating geometric digital twins for roads can increase productivity and help streamline predictive maintenance. However, the related costs outweigh foreseen financial gain due to the manual work needed in scene recognition and modelling. The foremost step in automatically creating such digital twins is segmenting objects in 3D point clouds. Researchers have done extensive work to tackle this challenge, with deep-learning solutions often preferable for solving multi-class problems. Yet, only several large-size road objects get high-quality detection results. Other essential but rather smaller objects represent a further challenge. We utilise common properties of roads and road assets in a lightweight deep learning network training and data pre-processing to facilitate a broader range of highly detected objects. We show how these priors improve detection performance by a significant margin. Our work contributes to the improved automatic detection of most road object types, enabling automatic digitisation for roads and reducing related costs.

description: It is proposed that "real" research issues are socially relevant, provide findings with utility beyond the profession, and are anticipatory. An industrializing agricultural sector, an evolving political economy of agroenvironmental policy, an increasingly transnational economy, and rapid population growth are important sources of change to which research on real agroenvironmental issues must respond. Specific, identified "real" research issue areas include: benefit-risk assessment methodology; agroenvironmental regulation for industrialized agriculture; trade agreements and environmental quality; the recreation-tourism-agriculture interface; sustainable development; and the formation of preferences. The nature of identified issues suggests more interdisciplinary research, and advances in theory and methodology.

Influences of weather and temperature on disease : implications for the population dynamics of western tent caterpillars
Creators: name: Frid, Leonardo
Publisher: name: University of British Columbia
Year: 2009

description: Studies on insect population outbreaks have failed to identify a single, general cause for population cycles. However, few studies have considered how various factors may together cause periodic outbreaks. Here I consider how disease and weather might interact to cause population cycles of western tent caterpillars, Malacosoma californicum pluviale (Dyar). A multiple regression analysis indicates that nuclearpolyhedrovirus (NPV) prevalence in western tent caterpillar populations increases with both host density and hours of sunshine during the larval feeding season. I explore the potential impact of climatic variability on population dynamics by modifying an existing model of caterpillar-disease dynamics to include uncorrelated stochastic variation in transmission rates between seasons in a manner that mimics the relationship between variability in spring weather and viral infection. Including stochasticity in transmission creates cyclic dynamics over a broader range of parameter space than in the deterministic model. Furthermore, simulated patterns of host density are more realistic when stochasticity in transmission rates is included in this model with outbreaks that vary among years in timing, amplitude and duration. Western tent caterpillars hatch in the early spring when temperatures are cool and variable. They compensate for suboptimal air temperatures by basking in the sun. To determine the impact of basking behaviour on the disease ecology of western tent caterpillars I examined the environmental determinants of larval body temperature and the effects of temperature on larval susceptibility to NPV. In the field, larval body temperature was determined by ambient temperature, solar irradiance and larval stage. The pathogenicity (LD50) of NPV was not influenced by temperature but the incubation time of the virus declined asymptotically as temperature increased. Basking behaviour of larvae and the associated increase in body temperature can strongly influence growth and development but has little impact on infection by NPV. Thus, an effect of temperature on the pathogenicity of NPV is not the mechanism by which disease prevalence is higher during sunnier years. Wanner temperatures attained by basking may increase the number of infection cycles in sunny springs but do not protect larvae from viral infection.

description: The FlexRay bus is a modern standard used in the automotive industry.It offers deterministic message transmission with zero jitter while using time-triggered scheduling in the static segment. When several vehicle variants (i.e. different models and their versions) share the same signal, the car manufacturers require to schedule such signal at the same time in all vehicle variants. This requirement simplifies the signal traceability and diagnostics in different vehicle variants using the same platform and simplifies reuse of components and tools. In this paper, we propose a first fit based heuristic algorithm which creates the schedules for several vehicle variants at once, while transmitting a given signal at the same time in all the schedules. The scheduling algorithm also takes the time constraints as release dates and deadlines into account. Finally, different algorithm versions are compared on benchmark sets and low computational time demands are validated on large instances.

description: Factors affecting the frequency of purchase of fish and other seafood for at-home and restaurant consumption by Northeastern consumers were investigated. Cluster analysis identified six groups of consumers with similar perceptions of the attributes of fish. Demographic and cluster membership variables were employed in logistic regressions to identify the characteristics of frequent at-home use and restaurant purchasers. At-home purchase was more likely to be frequent among respondents with white collar occupations, older ages, urban/suburban and New England residence, recreational fishing participation, and membership in one of five attitudinal clusters. Restaurant purchase was more likely to be frequent among whites and among those with higher incomes, white collar occupations, recreational fishing involvement and among members of two clusters with favorable attitudes toward fish; it was less likely to be frequent in households with children age 10 and under present.

We explain that a lot of classical differential geometric constructions in the context can be conveniently described using the language of Q-structures, and thus Q-structure preserving integrators are potentially of great use in mechanics. We give some hints how the latter can be constructed, and formulate some open problems. Since the text is intended both to mathematics and mechanics communities, we tried to make it accessible to non-geometers as well.

Massive stars and the energy balance of the interstellar medium. II. The 35 solar mass star and a solution to the "missing wind problem"

description: We continue our numerical analysis of the morphological and energetic influence of massive stars on their ambient interstellar medium for a 35 solar mass star that evolves from the main sequence through red supergiant and Wolf-Rayet phases, until it ultimately explodes as a supernova. We find that structure formation in the circumstellar gas during the early main-sequence evolution occurs as in the 60 solar mass case but is much less pronounced because of the lower mechanical wind luminosity of the star. Since on the other hand the shell-like structure of the HII region is largely preserved, effects that rely on this symmetry become more important. At the end of the stellar lifetime 1% of the energy released as Lyman continuum radiation and stellar wind has been transferred to the circumstellar gas. From this fraction 10% is kinetic energy of bulk motion, 36% is thermal energy, and the remaining 54% is ionization energy of hydrogen. The sweeping up of the slow red supergiant wind by the fast Wolf-Rayet wind produces remarkable morphological structures and emission signatures, which are compared with existing observations of the Wolf-Rayet bubble S308. Our model reproduces the correct order of magnitude of observed X-ray luminosity, the temperature of the emitting plasma as well as the limb brightening of the intensity profile. This is remarkable, because current analytical and numerical models of Wolf-Rayet bubbles fail to consistently explain these features. A key result is that almost the entire X-ray emission in this stage comes from the shell of red supergiant wind swept up by the shocked Wolf-Rayet wind rather than from the shocked Wolf-Rayet wind itself as hitherto assumed and modeled. This offers a possible solution to what is called the ``missing wind problem'' of Wolf-Rayet bubbles.

description: We assess the nonmarket value for retention of farmland in the Moncton area of New Brunswick. We examine a number of factors explaining household external values for farmland preservation and expand on previous work by Beasley et al., Bergstrom et al., and Halstead. Our findings indicate that the marginal external benefit of preserving farmland in general in this region is small compared to the market price and that spatial embedding is not automatic in contingent valuation studies.

description: Context: The Faraday rotation measure (RM) is often used to study the magnetic field strength and orientation within the ionized medium of the Milky Way. Observations indicate a RM in the spiral arms that exceeds the commonly assumed range. This raises the question of under what conditions spiral arms create such strong RM. Aims: We investigate the effect of spiral arms on Galactic RMs through shock compression of the interstellar medium (ISM). It has recently been suggested that the Sagittarius spiral arm creates a strong peak in RM where the line of sight (LOS) is tangent to the arm, and that enhanced RM follows along an intersecting LOS. We seek to understand the physical conditions that give rise to this effect and the role of viewing geometry. Methods: We apply a MHD simulation of the multi-phase ISM in a Milky Way type spiral galaxy disk in combination with radiative transfer to evaluate different tracers of spiral arm structures. For observers embedded in the disk, dust intensity, synchrotron emission and the kinematics of molecular gas observations are derived to identify spiral arm tangents. RMs are calculated through the disk and evaluated for different observer positions. The observer's perspective is related to the parameters of the local bubble surrounding the observer. Results: We reproduce a scattering of tangent points for different tracers of about $6^\circ$ per spiral arm similar to the Milky Way. As for the RM, the model shows that compression of the ISM and associated amplification of the magnetic field in spiral arms enhances RM by a few hundred rad $m^{-2}$ on top of the mean contribution of the disk. The arm-inter-arm contrast in RM along the LOS is approximately 10 in the inner Galaxy, fading to ~2 in the outer Galaxy. We identify a shark-fin like pattern in the RM Milky Way observations as well as the synthetic data that is characteristic for spiral arms.

description: Response rates are one indicator of a survey's data quality, as a great deal of importance has been placed on the mail survey's response rate. However, a telephone survey's response rate usually is not reported. Even if one is reported, the numbers used in the calculation are rarely defined making the response rate interpretation unclear. Using a recent telephone survey of Pennsylvania dairy managers, this paper demonstrates how telephone survey data should be reported. Essentially, every research report should include a discussion of how the survey was conducted, a disposition table, and well-defined formulas used to calculate response rates.
AN ANALYSIS OF POLICY ALTERNATIVES TO THE DAIRY PRICE SUPPORT PROGRAM

Publisher: name: Unknown
Year: 1994
Subjects: Agricultural and Food Policy

description: This paper investigates the impacts of alternative federal dairy policies on the U.S. dairy sector. In addition to the current dairy price support program, five alternatives are investigated: (1) immediate deregulation, (2) gradual deregulation, (3) target price-deficiency payment program without supply control, (4) target price-deficiency payment program with supply control, and (5) mandatory supply control. An econometric model of the national dairy industry is used to simulate quarterly equilibrium price and quantity values at the farm and wholesale levels for each policy over the period 1980-90. Consumers are better off under both immediate and gradual deregulation, as well as the target price-deficiency payment scenarios because prices are lower, enabling them to consume more dairy products. Farmers, as a group, are better off under the two target price-deficiency payment program and supply control scenarios, where milk prices and producer surplus are highest.

description: We report fabrication of low loss single mode waveguides on lithium niobate on insulator (LNOI) cladded by a layer of SiO2. Our technique, termed photolithography assisted chemo-mechanical etching (PLACE), relies on patterning of a chromium film into the mask shape by femtosecond laser micromachining and subsequent chemo-mechanical etching of the lithium niobate thin film. The high-index-contrast single mode waveguide is measured to have a propagation loss of 0.13 dB/cm. Furthermore, waveguide tapers are fabricated for boosting the coupling efficiency.

SCANNER DATA: NEW OPPORTUNITIES FOR DEMAND AND COMPETITIVE STRATEGY ANALYSIS

Year: 1994
Subjects: Demand and Price Analysis

description: This paper reviews prior research by agricultural economists on the demand for food products using scanner data. Thereafter, a differentiated product's oligopoly model with Bertrand price competition is developed and used to specify brand level demand and oligopoly price reaction equations. The model has sufficient detail to estimate brand level price elasticities and price response elasticities which in turn can be used to estimate three indices of market power. The first index estimated is the familiar Rothschild Index. The paper develops estimates two new indexes, the observed index and the Chamberlin quotient for tacit collusion. It concludes with comments on how the proposed method for the measurement of market power in a differentiated oligopoly can be improved.

description: It is experimentally demonstrated that an arbitrary quantum state of a single spin 1/2: a|u> + b|d> can be converted into a superposition of the two ferromagnetic states of a spin cluster: a|uu...uu> + b|dd...dd>. The physical system is a cluster of seven dipolar-coupled nuclear spins of single-labeled 13C-benzene molecules in a liquid-crystalline matrix. In this complex system, the pseudopure ground state and the required controlled unitary transformations have been implemented. The experimental scheme can be considered as an explicit model of quantum measurement.

Protection against leishmaniasis by DNA injection of a plasmid encoding the Leishmania major Cpn60 gene
Creators: name: Webber, Jane
Publisher: name: University of British Columbia
Year: 2009

description: The leishmaniases are parasitic protozoan infections caused by members of the genus Leishmania. Injection of Leishmania major into various strains of inbred mice cause disease symptoms which mimic the symptoms of a human leishmanial infection. Protection against an L. major infection in BALB/c mice depends on the generation of a macrophage-activating CD4 ⁺ Th1 immune response with production of IL-2 and IFNγ, but not IL-4, a Th2 cytokine that results in disease exacerbation. Immunization using DNA vaccines is a promising new approach for the prevention of diseases caused by intracellular pathogens. The antigen of interest encoded in the plasmid is transcribed and translated by the host cellular machinery and presented to the immune system inducing specific cell-mediated and humoral immune responses against the encoded protein. In this study a eukaryotic expression vector, pcDNA3.1 encoding the L. major chaperonin 60 (Cpn60) was constructed and tested in vitro to confirm that the mammalian translational machinery could synthesize the protein. Cell-free coupled transcription/translation using rabbit reticulocyte lysate and transfection studies using COS-7 cells were carried out by SDS-PAGE and western blot analysis of protein products. A single protein of the correct size was produced in vaccine samples but not in the Controls. To test the vaccine efficacy, BALB/c mice were immunized with either the vaccine construct, empty plasmid control or PBS, and boosted twice two weeks apart. Spleen cells from mice immunized with the vaccine construct did not produce significant amounts of the Thl cytokines interleukin-2 (IL-2) or gamma interferon (IFN-γ), or the Th2 cytokine IL-4, when cultured with soluble Leishmania antigen (SLA) in vitro. Sera from each mouse group was pooled and used to probe immunoblots where protein from control organisms, purified human Cpn60 and L. major total protein was used as antigen. Sera from the vaccine mouse group did not detect the L. major Cpn60 protein. The results of these experiments indicated that the protein was expressed in vitro but immunization experiments were unsuccessful using this vaccination protocol. Review of vaccination techniques and a change in the immunization site may improve chances for a successful outcome.
ENVIRONMENTAL ECONOMIC RESEARCH HAS AN AUDIENCE BUT NOT A SPONSOR: DISCUSSION

description: There exists no mechanism for federal agencies, national laboratories, industry, and academic institutions to set a national environmental research agenda. Moreover, funding for social science research is inadequate for providing a sound scientific basis for making environmental policy. Despite this lack of leadership, it is quite possible to define an environmental economic research agenda that could lead to improved policies for protecting and managing the environment. The present paper makes some recommendations from an insider's viewpoint.

description: AJAE per capita page counts provide one measure of an institution's research strength. In this article we refine Willis et al.'s measure of department size and, based on the refined measure, recomputed departmental rankings for North American institutions. Results indicate that Northeastern United States departments are more widely represented among the top 20 institutions than 20 years ago and that two Canadian institutions-Guelph and British Columbia-rank in the top 12. The median AJAE publication frequency for the top 30 research institutions is about one article per research faculty member every 12 years. The AJAE page-count measure was found to be highly correlated (R2 = 0.82) with citation counts, whether narrowly or broadly defined. Thus, AJAE page counts appear to provide a simple yet valid representation of institutional research productivity.

description: Managing quality risks, especially grain quality, has been a challenge facing farmers, grain merchandisers, and policymakers for many years. With the advent of genetically modified organisms (GMOs), food safety, and identity preservation, this is even more challenging today. In this paper, an equilibrium crop insurance model was developed and used to analyze the impact of quality risks on equilibrium coverage levels and risk premiums that suppliers of insurance and barley producers would be willing to provide when yield and revenue insurance instruments explicitly incorporate quality risks. The asking price concept and sensitivity analysis were used to evaluate farmers' behavior after they purchase crop quality insurance and to provide guidance and direction in the development of risk-efficient quality insurance instruments.
