description: Americans spent about 46 percent of their total food budget on food away from home in 2002, up from 27 percent in 1962. Such foods tend to be less nutritious and higher in calories than foods prepared at home, and some studies have linked eating away from home to overweight and obesity in adults and children. Current nutrition labeling law exempts much of the food-away-from-home sector from mandatory labeling regulations. Because consumers are less likely to be aware of the ingredients and nutrient content of away-from-home food than of foods prepared at home, public health advocates have called for mandatory nutrition labeling for major sources of food away from home, such as fast-food and chain restaurants. This report provides an economic assessment of a food-away-from home nutrition labeling policy, including justifications for policy intervention and potential costs and benefits of the policy.

description: Three-flavor lattice QCD simulations and two-loop perturbation theory are used to make the most precise determination to date of the strange-, up-, and down-quark masses, $m_s$, $m_u$, and $m_d$, respectively. Perturbative matching is required in order to connect the lattice-regularized bare- quark masses to the masses as defined in the \msbar scheme, and this is done here for the first time at next-to-next-to leading (or two-loop) order. The bare-quark masses required as input come from simulations by the MILC collaboration of a highly-efficient formalism (using so-called ``staggered'' quarks), with three flavors of light quarks in the Dirac sea; these simulations were previously analyzed in a joint study by the HPQCD and MILC collaborations, using degenerate $u$ and $d$ quarks, with masses as low as $m_s/8$, and two values of the lattice spacing, with chiral extrapolation/interpolation to the physical masses. With the new perturbation theory presented here, the resulting \msbar\ masses are $m^\msbar_s(2 {GeV}) = 87(0)(4)(4)(0)$ MeV, and $\hat m^\msbar(2 {GeV}) = 3.2(0)(2)(2)(0)$ MeV, where $\hat m = \sfrac12 (m_u + m_d)$ is the average of the $u$ and $d$ masses. The respective uncertainties are from statistics, simulation systematics, perturbation theory, and electromagnetic/isospin effects. The perturbative errors are about a factor of two smaller than in an earlier study using only one-loop perturbation theory. Using a recent determination of the ratio $m_u/m_d = 0.43(0)(1)(0)(8)$ due to the MILC collaboration, these results also imply $m^\msbar_u(2 {GeV}) = 1.9(0)(1)(1)(2)$ MeV and $m^\msbar_d(2 {GeV}) = 4.4(0)(2)(2)(2)$ MeV. A technique for estimating the next order in the perturbative expansion is also presented, which uses input from simulations at more than one lattice spacing.

description: Abstract

Background: Pre-hospital care in Malaysia mostly consisted of Assistant Medical Officers (AMOs) and nurses played a big role in minimizing the consequences of the injuries by conducting a good assessment and executing the correct clinical treatment on scene before reaching the hospital. However, there is no structured training and competency program for pre-hospital personnel in the studied setting. Aim: The present study aimed to identify the baseline knowledge and skills of AMOs and nurses in prehospital care at Sultan Ahmad Shah Medical Center @ International Islamic University Malaysia (SASMEC @ IIUM). Method: This study employed a self-administered questionnaire that originated from the WHO's Essential Knowledge and Skills Questionnaire for prehospital care, using a cross-sectional survey design and convenience sampling. Pre-hospital care knowledge, skills, and demographic characteristics are all included in the questionnaire. The SASMEC @ IIUM Emergency and Trauma Department is where the data were collected. Result: A total of 73 participants participated in this survey. The perceived level of knowledge and skills of AMOs and nurses in prehospital care at SASMEC @ IIUM are still not completely performed as a whole, based on all the elements required in the self-evaluation questionnaire are not fully recognized and mastered. Nonetheless, there is a positive association (p < 0.000) between the AMOs and nurses' knowledge and abilities, indicating that the more prehospital care a person knows, the more proficient they are in providing it. Conclusion: This study's findings indicated that a specific initiative should be taken to enhance the prehospital service by providing structured in-house training.

description: The Gaia early Data Release 3 has delivered exquisite astrometric data for 1.47 billion sources, which is revolutionizing many fields in astronomy. For a small fraction of these sources, the astrometric solutions are poor, and the reported values and uncertainties may not apply. Before any analysis, it is important to recognize and excise these spurious results - this is commonly done by means of quality flags in the Gaia catalog. Here, we devise a means of separating 'good' from 'bad' astrometric solutions that is an order of magnitude cleaner than any single flag: 99.3% pure and 97.3% complete, as validated on our test data. We devise an extensive sample of manifestly bad astrometric solutions, with parallax that is negative at > 4.5 sigma; and a corresponding sample of presumably good solutions, including sources in HEALPix pixels on the sky that do not contain such negative parallaxes, and sources that fall on the main sequence in a color-absolute magnitude diagram. We then train a neural network that uses 17 pertinent Gaia catalog entries and information about nearby sources to discriminate between these two samples, captured in a single 'astrometric fidelity' parameter. A diverse set of verification tests shows that our approach works very cleanly, including for sources with positive parallaxes. The main limitations of our approach are in the very low-SNR and the crowded regime. Our astrometric fidelities for all of eDR3 can be queried via the Virtual Observatory, our code and data are public.

Mercurian impact ejecta: Meterorites and mantle

description: We have examined the fate of impact ejecta liberated from the surface of Mercury due to impacts by comets or asteroids, in order to study (1) meteorite transfer to Earth, and (2) re-accumulation of an expelled mantle in giant-impact scenarios seeking to explain Mercury's large core. In the context of meteorite transfer, we note that Mercury's impact ejecta leave the planet's surface much faster (on average) than other planet's in the Solar System because it is the only planet where impact speeds routinely range from 5-20 times the planet's escape speed. Thus, a large fraction of mercurian ejecta may reach heliocentric orbit with speeds sufficiently high for Earth-crossing orbits to exist immediately after impact, resulting in larger fractions of the ejecta reaching Earth as meteorites. We calculate the delivery rate to Earth on a time scale of 30 Myr and show that several percent of the high-speed ejecta reach Earth (a factor of -3 less than typical launches from Mars); this is one to two orders of magnitude more efficient than previous estimates. Similar quantities of material reach Venus. These calculations also yield measurements of the re-accretion time scale of material ejected from Mercury in a putative giant impact (assuming gravity is dominant). For mercurian ejecta escaping the gravitational reach of the planet with excess speeds equal to Mercury's escape speed, about one third of ejecta re-accretes in as little as 2 Myr. Thus collisional stripping of a silicate proto-mercurian mantle can only work effectively if the liberated mantle material remains in small enough particles that radiation forces can drag them into the Sun on time scale of a few million years, or Mercury would simply re-accrete the material.

description: This paper constructs and analyses a long run time series for regional inequality in China from the Communist Revolution to the present. There have been three peaks of inequality in the last fifty years, coinciding with the Great Famine of the late 1950s, the Cultural Revolution of the late 1960s and 1970s, and finally the period of openness and global integration in the late 1990s. Econometric analysis establishes that regional inequality is explained in the different phases by three key variables--the ratio of heavy industry to gross output value, the degree of centralization, and the degree of openness.

description: Squeezed light enables measurements with sensitivity beyond the quantum noise limit (QNL) for optical techniques such as spectroscopy, gravitational wave detection, magnetometry and imaging. Precision of a measurement -- as quantified by the variance of repeated estimates -- has also been enhanced beyond the QNL using squeezed light. However, sub-QNL sensitivity is not sufficient to achieve sub-QNL precision. Furthermore, demonstrations of sub-QNL precision in estimating transmission have been limited to picowatts of probe power. Here we demonstrate simultaneous enhancement of precision and sensitivity to beyond the QNL for estimating modulated transmission with a squeezed amplitude probe of 0.2 mW average (25 W peak) power, which is 8 orders of magnitude above the power limitations of previous sub-QNL precision measurements of transmission. Our approach enables measurements that compete with the optical powers of current classical techniques, but have both improved precision and sensitivity beyond the classical limit.

description: Income volatility challenges the effectiveness of the safety net that USDA food assistance programs provide low-income families. This study examines income volatility among households with children and the implications of volatility for eligibility in the National School Lunch Program (NSLP). The results show that income volatility was higher for successively lower income groups and that the major determinants of changes in NSLP eligibility were changes in total household hours worked and the share of working adults. Income volatility in two-thirds of lower income households caused one or more changes in their monthly NSLP eligibility during the year. An estimated 27 percent of households that were income eligible for subsidized lunches at the beginning of the school year were no longer income eligible for the same level of subsidy by December due to monthly income changes.

This study investigates the micro/nanostructural features and mechanical responses of a novel TiAl/Ti3Al/Al2O3 cermet fabricated by self-propagation high-temperature synthesis. The microscopic diagnosis was used to examine the material composition, phase distribution, and elemental concentration of the cermet. Three phases were identified in the cermet, including γ-TiAl, α2-TiAl, and Al2O3. The material exhibited ultrafine microstructure with the size of alumina particles between 0.5 µm and 1.5 µm occupying 65 ± 1% areal fraction of the material. Transmission electron microscopy (TEM) was employed to examine the “coral” network of alumina particles with the titanium aluminide matrix, which was believed to be contributing to the failure of the material. Iron/nickel-based nano-precipitates were found through TEM as well, and these were believed to be contributing to the mechanical properties of the material. The rate-dependency on the compressive strength and failure mechanisms were studied by quasi-static and dynamic uniaxial compression, and it was found that the quasi-static and dynamic compressive strengths were 2400 ± 120 MPa and 3370 ± 450 MPa, respectively. The results are compared with those for alumina AD995 to highlight differences in mechanical properties, such as compressive strength and failure strains. These findings serve as the preliminary dataset for material design, manufacturing, and modeling of advanced cermets.

description: Over the past 10 years, the growth of nontraditional retail food outlets has transformed the food market landscape, increasing the variety of shopping and food options available to consumers, as well as price variation in retail food markets. This report focuses on these dynamics and how they affect food price variation across store format types. The differences in prices across store formats are especially noteworthy when compared with standard measures of food price inflation over time. Over the past 20 years, annual food price changes, as measured by the Consumer Price Index (CPI), have averaged just 3 percent per year, while food prices for similar products can vary by more than 10 percent across store formats at any one point in time. Since the current CPI for food does not fully take into account the lower price option of nontraditional retailers, a gap exists between price change as measured using scanner data versus the CPI estimate, even for the relatively low food inflation period of 1998-2003.

description: Thermal management is extremely important for designing high-performance devices. The lattice thermal conductivity of materials is strongly dependent on the structural defects at different length scales, particularly point defects like vacancies, line defects like dislocations, and planar defects such as grain boundaries. Traditionally, the McKelvey-Shockley phonon Boltzmann's transport equation (BTE) method combined with molecular dynamics simulations has been widely used to evaluate the phonon mean free paths (MFPs) in defective systems. However, this method can only provide the aggregate MFPs of the whole sample. It is, therefore, challenging to extract the MFPs in the different regions with different thermal properties. In this study, the 1D McKelvey-Shockley phonon BTE method was extended to model inhomogeneous materials, where the effect of defects on the phonon MFPs is explicitly obtained. Then, the method was used to study the phonon interactions with the core structure of an edge dislocation. The phonon MFPs in the dislocation core were obtained and consistent with the analytical model such that high frequency phonons are likely to be scattered in this area. This method not only advances the knowledge of phonon-dislocation scattering but also shows the potential to investigate phonon transport behaviors in more complicated materials.

description: We present a very general argument that the analogue of a heavy pentaquark (a state with the quantum numbers of a baryon combined with an additional light quark and a heavy antiquark) must exist as a particle stable under strong interactions in the combined heavy quark and large Nc limits of QCD. Moreover, in the combined limit these heavy pentaquark states fill multiplets of SU(4)xO(8)xSU(2). We explore the question of whether corrections in the combined 1/Nc and 1/mQ expansions are sufficiently small to maintain this qualitative result. Since no model-independent way is known to answer this question, we use a class of ``realistic'' hadronic models in which a pentaquark can be formed via nucleon-heavy meson binding through a pion-exchange potential. These models have the virtue that they necessarily yield the correct behavior in the combined limit, and the long-distance parts of the interactions are model independent. If the long-distance attraction in these models were to predict bound states in a robust way (i.e., largely insensitive to the details of the short-range interaction), then one could safely conclude that heavy pentaquarks do exist. However, in practice the binding does depend very strongly on the details of the short-distance physics, suggesting that the real world is not sufficiently near the combined large Nc, mQ limit to use it as a reliable guide. Whether stable heavy pentaquarks exist remains an open question.

description: The contemporary view of competitiveness and strategy is based on the foundation that customer value is created by firms working together for common aims and not created by firms working in isolation. Therefore there is increasing recognition that firms who engage in co-operative long-term partnerships, improve the operation of the supply chain as a whole for the mutual benefit of all parties involved. However researchers have suggested that the degree of partnership that develops between a buyer and a supplier, and the performance outcomes achieved, are likely to be moderated by firm, market or product characteristics. Therefore using data collected from a survey of UK fresh produce suppliers, this study investigates how differences, in terms of size, type of product supplied, number and type of customers supplied, and the length of the customer relationship, influences the development and performance of buyer-supplier relationships in the UK fresh produce industry.

The method has no drawbacks compared to previous parquet solvers but has the significant advantage that the vertex functions decay quickly with frequencies and with respect to distances in real space. These properties coincide with the respective separation of the length and energy scales of the two-particle correlations into long/short-ranged and high/low-energetic.

description: Multifunctionality is one of the key issues and concepts in European agriculture and in the common agricultural policy. Its importance is further emphasized in the context of the WTO negotiations. Stronger emphasis on multifunctionality will also have significant impacts on the food and agribusiness sector. Yet, so far consumers' views on multifunctionality have mostly been neglected in both policy planning and research. This paper presents one of the first major surveys on consumers' attitudes towards and willingness to pay for multifunctional agriculture. The study is based on a modern computer aided interviewing system and the contingent valuation method was employed to find out the WTP.

description: We explore the conjectured duality between a class of large $N$ matrix integrals, known as multicritical matrix integrals (MMI), and the series $(2m-1,2)$ of non-unitary minimal models on a fluctuating background. We match the critical exponents of the leading order planar expansion of MMI, to those of the continuum theory on an $S^2$ topology. From the MMI perspective this is done both through a multi-vertex diagrammatic expansion, thereby revealing novel combinatorial expressions, as well as through a systematic saddle point evaluation of the matrix integral as a function of its parameters. From the continuum point of view the corresponding critical exponents are obtained upon computing the partition function in the presence of a given conformal primary. Further to this, we elaborate on a Hilbert space of the continuum theory, and the putative finiteness thereof, on both an $S^2$ and a $T^2$ topology using BRST cohomology considerations. Matrix integrals support this finiteness.

description: The $SU(3)_C X SU(3)_L X U(1)_X$ gauge model with the minimal scalar sector (two Higgs triplets) is studied in detail. One of the vacuum expectation values $u$ is a source of lepton-number violations and a reason for the mixing among the charged gauge bosons - the standard model $W$ and the bilepton (with L=2) gauge bosons as well as among neutral non-Hermitian $X^0$ and neutral gauge bosons: the photon, the $Z$ and the new $Z'$. Because of these mixings, the lepton-number violating interactions exist in both charged and neutral gauge boson sectors. An exact diagonalization of the neutral gauge boson sector is derived and bilepton mass splitting is also given. The lepton-number violation happens only in the neutrino but not in the charged lepton sector. In this model, lepton-number changing ($ΔL = \pm 2$) processes exist but "only" in the neutrino sector. Constraints on VEVs of the model are estimated and $u \simeq \emph{O}(1) \textrm{GeV}$, $v \simeq v_{weak} = 246 \textrm{GeV}$ and $\om \simeq \emph{O}(1) \textrm{TeV}$.

description: We analyze the transport properties of two artificial magnetic impurities coupled togethervia a tunable RKKY interaction mediated by conduction electrons of a finite size one dimensional wire. We show that the sign of the RKKY interaction can be controlled by gating the wire. We investigate the interplay between finite size effects and RKKY interaction and found that the two artificial impurities start to interact each-other as soon as the Kondo screening cloud length becomes larger that the length of the wire. This should allow to give a lower experimental estimate of the Kondo screening cloud length.

description: The elastic scattering of two real photons in vacuum is one of the most elusive of the fundamentally new processes predicted by quantum electrodynamics. This explains why, although it was first predicted more than eighty years ago, it has so far remained undetected. Here we show that in present-day facilities, the elastic scattering of two real photons can become detectable far off axis in an asymmetric photon-photon collider setup. This may be obtained within one day of operation time by colliding 1 mJ extreme ultraviolet pulses with the broadband gamma-ray radiation generated in nonlinear Compton scattering of ultrarelativistic electron beams with terawatt-class optical laser pulses operating at a 10 Hz repetition rate. In addition to the investigation of elastic photon-photon scattering, this technique allows us to unveil or constrain new physics that could arise from the coupling of photons to yet undetected particles, therefore opening new avenues for searches of physics beyond the standard model.

description: Standard pavement types and experimental surfaces on roads throughout Kentucky were evaluated in terms of skid resistance and effects of traffic, wear, and polishing. Friction-vs-speed gradients and the relationships between locked-wheel and incipient friction were determined. Class I bituminous pavements on high-speed, four-lane roads were found to be significantly more skid resistant than on two-lane highways and somewhat more skid resistant than concrete surfaces (especially those containing calcareous gravel aggregates). Sand-asphalt surfaces containing significant proportions of limestone sands showed inadequate level of friction for the traffic sustained. Several experimental sand asphalts without limestone sands exhibited greater skid resistance; Kentucky rock asphalt surfaces remain the most skid resistant of all surfaces investigated.

description: Creolé Coffee had just started to achieve regional and national success. However,recent volatility in the world coffee market resulted not only in price instabilities, but also created difficulty in procuring the high-quality product customers had grown to expect from Creolé. In examining this situation, Jim Brewer determined that the company must adapt their relationships with producers to ensure the availability of the quality and quantity of coffee needed to produce the premium blends consumers now associate with Creolé. In turn this would allow the company to provide consumers with a high quality product at a stable price.

description: Verification of patient specific proton stopping powers obtained in the patient treatment position can be used to reduce the distal margins needed in particle beam planning. Proton radiography can be used as a pre-treatment instrument to verify integrated stopping power consistency with the treatment planning CT. Although a proton radiograph is a pixel by pixel representation of integrated stopping powers, the image may also be of high enough quality and contrast to be used for patient alignment. This investigation qualifies the accuracy and image quality of a prototype proton radiography system on a clinical proton delivery system. We have developed a clinical prototype proton radiography system designed for integration into efficient clinical workflows. We tested the images obtained by this system for water-equivalent thickness (WET) accuracy, image noise, and spatial resolution. We evaluated the WET accuracy by comparing the average WET and rms error in several regions of interest (ROI) on a proton radiograph of a custom peg phantom. We measured the spatial resolution on a CATPHAN Line Pair phantom and a custom edge phantom by measuring the 10% value of the modulation transfer function (MTF). In addition, we tested the ability to detect proton range errors due to anatomical changes in a patient with a customized CIRS pediatric head phantom and inserts of varying WET placed in the posterior fossae of the brain. We took proton radiographs of the phantom with each insert in place and created difference maps between the resulting images. Integrated proton range was measured from an ROI in the difference maps.

Waves, scale, sand, and water : dielectric constant of unconsolidated sediments
Creators: name: Chan, Christina Ye
Publisher: name: University of British Columbia

description: Field dielectric measurements are used to estimate the water content of the subsurface. In order to estimate water content accurately, the Earth's heterogeneity should be taken into account. Layering is a simple form of heterogeneity which is a close approximation in many sedimentary environments. The interplay between the average layer thickness of a sedimentary system and the wavelength of the EM wave used for the dielectric measurement is important in determining average dielectric constant. When the layers are thick compared to the wavelength, the system falls under the ray theory regime; when the layers are thin, the system falls under the effective medium theory regime. Using numerical and experimental techniques, I confirm these two regimes. I also investigate the transition zone between the regimes and find that it falls at a wavelength to layer thickness ratio of around 4. The breadth of the zone is affected by the dielectric constants of the components, the proportions of the components, and the distribution of the layers, but not the conductivity of the soils. Because many sedimentary environments have layering, the presence of these layers must be accounted for when using the average dielectric constant measured in the field to estimate water content. I compare relationships between dielectric constant and water content which take into account the presence of layering with relationships which assume homogeneity. Modeling dielectric constant as a function of lithology and water content, I find differences among the dielectric constants predicted from the different relationships. I show the potential error in water content estimation if a layered system is assumed to be homogeneous. I also present a flow chart for more accurately estimating water content and saturation from field measurements. This method not only gives the global water content of the whole system but also gives the water contents of the individual sedimentary layers if they are present. In this thesis, I present research which can provide more accurate estimates of water content from dielectric measurements. These investigations advance the knowledge of EM wave propagation and increase the accuracy of estimating water content from field dielectric measurements of the subsurface.

description: Many clues about the galaxy assembly process lurk in the faint outer regions of galaxies. The low surface brightnesses of these parts pose a significant challenge for studies of diffuse light, and few robust constraints on galaxy formation models have been derived to date from this technique. Our group has pioneered the use of extremely wide-area star counts to quantitatively address the large-scale structure and stellar content of external galaxies at very faint light levels. We highlight here some results from our imaging and spectroscopic surveys of M31 and M33.

description: Building accurate and flexible galaxy-halo connection models is crucial in modeling galaxy clustering on non-linear scales. Recent studies have found that halo concentration by itself cannot capture the full galaxy assembly bias effect and that the local environment of the halo can be an excellent indicator of galaxy assembly bias. In this paper, we propose an extended halo occupation distribution model (HOD) that includes both a concentration-based assembly bias term and an environment-based assembly bias term. We use this model to achieve a good fit (chi^2/DoF = 1.35) on the 2D redshift-space 2-point correlation function (2PCF) of the Baryon Oscillation Spectroscopic Survey (BOSS) CMASS galaxy sample. We find that the inclusion of both assembly bias terms is strongly favored by the data and the standard 5-parameter HOD is strongly rejected. More interestingly, the redshift-space 2PCF drives the assembly bias parameters in a way that preferentially assigns galaxies to lower mass halos. This results in galaxy-galaxy lensing predictions that are within 1sigma agreement with the observation, alleviating the perceived tension between galaxy clustering and lensing. We also showcase a consistent 3-5sigma preference for a positive environment-based assembly bias that persists over variations in the fit. We speculate that the environmental dependence might be driven by underlying processes such as mergers and feedback, but might also be indicative of a larger halo boundaries such as the splashback radius. Regardless, this work highlights the importance of building flexible galaxy-halo connection models and demonstrates the extra constraining power of the redshift-space 2PCF.

description: Non-Abelian discrete symmetries have been widely used to explain the patterns of lepton masses and flavor mixing. In these models, a given symmetry is assumed at a high scale and then is spontaneously broken by scalars (the flavons), which acquire vacuum expectation values. Typically, the resulting leading order predictions for the oscillation parameters require corrections in order to comply with neutrino oscillation data. We introduce such corrections through an explicit small breaking of the symmetry. This has the advantage of solving the cosmological problems of these models without resorting to inflation. The explicit breaking induces an energy difference or "bias" between different vacua and drives the evolution of the domain walls, unavoidably produced after the symmetry breaking, towards their annihilation. Importantly, the wall annihilation leads to gravitational waves which may be observed in current and/or future experiments. We show that a distinctive pattern of gravitational waves with multiple overlapped peaks is generated when walls annihilate, which is within the reach of future detectors. We also show that cosmic walls from discrete flavor symmetries can be cosmologically safe for any spontaneous breaking scale between 1 and $10^{18}$ GeV, if the bias is chosen adequately, without the need to inflate the walls away. We use as an example a particular $A_4$ model in which an explicit breaking is included in right-handed neutrino mass terms.
