description: This study provides insight into the seasonality of Class I price differentials in the southeastern dairy industry. This is accomplished by analyzing monthly estimates of Class I price differentials obtained from the imputed price solution or dual solution of a generalized capacitated minimum cost network flow model of the dairy industry. A smooth seasonal pattern emerges through the monthly sequence with the lowest and highest estimated Class I price differentials occurring in April and September respectively. Miami and Jacksonville areas reach $5.40 and $4.36 per hundredweight in April and $6.79 and $5.53 per hundredweight in September.

description: Economists and others need estimates of future cash price volatility to use in risk management evaluation and education programs. This paper evaluates the performance of alternative volatility forecasts for fed cattle, feeder cattle, and corn cash price returns. Forecasts include time series (e.g. GARCH), implied volatility from options on futures contracts, and composite specifications. The overriding finding from this research, consistent with the existing volatility forecasting literature, is that no single method of volatility forecasting provides superior accuracy across alternative data sets and horizons. However, evidence is provided suggesting that risk managers and extension educators use composite methods when both time series implied volatilities are available.

description: Farmers are interested in knowing whether applying inputs at variable rates across a field is economically viable. The answer depends on the crop, the input, their prices, the cost of variable rate technology (VRT) versus uninform rate technology (URT), and the spatial and yield response variability within each field. Methods were investigated for determining the range of spatial variability over which the return to VRT covers its additional cost compared with URT in fields with multiple management zones. Models developed in this article, or variants thereof, could be used to help farmers make the VRT adoption decision.

description: The Dixit-Pindyck model was applied to examine the hypothesis that uncertainty associated with grapefruit production costs and returns is an important determinant of Texas grapefruit growers' investment behavior. Freezes, price variability, and the effects of expanded trade were analyzed as risk factors. An investment decision rule based on a net-present value calculation would approve a 25-year commitment to a 20-acre grapefruit grove, given a 6-percent discount rate. The modified hurdle rate, calculated using an ex ante version of the Dixit-Pindyck model, is 24 percent. The major source of the risk borne by Texas grapefruit investors is from freezes, rather than from expanded trade.

description: Woody plant encroachment restricts forage production and capacity to produce grazing livestock. Biophysical plant growth simulation and economic simulation were used to evaluate a prescribed burning range management technique. Modeling systems incorporated management practices and costs, historical climate data, vegetation and soil inventories, livestock production data, and historical regional livestock prices. The process compared baseline non-treatment return estimates to expected change in livestock returns resulting from prescribed burning. Stochastic analyses of production and price variability produced estimates of greater net returns resulting from use of prescribed burning relative to the baseline.

description: We investigate the decay of particles with the quantum numbers of the gluino. Besides SUSY, such particles may be present in models where the Higgs and top are composite. We find that such 'composite' gluinos have decay signatures similar to those of gluinos in 'more minimal' SUSY type models. Though it is in principle possible to distinguish the two scenarios, we find that it will be a challenging task at the LHC. This puts into question the common lore that a gluino is an obvious 'smoking-gun' signature of SUSY.

description: Materials made from active, living, or robotic components can display emergent properties arising from local sensing and computation. Here, we realize a freestanding active metabeam with piezoelectric elements and electronic feed-forward control that gives rise to an odd micropolar elasticity absent in energy-conserving media. The non-reciprocal odd modulus enables bending and shearing cycles that convert electrical energy into mechanical work, and vice versa. The sign of this elastic modulus is linked to a non-Hermitian topological index that determines the localization of vibrational modes to sample boundaries. At finite frequency, we can also tune the phase angle of the active modulus to produce a direction-dependent bending modulus and control non-Hermitian vibrational properties. Our continuum approach, built on symmetries and conservation laws, could be exploited to design others systems such as synthetic biofilaments and membranes with feed-forward control loops.

description: The detection of TeV gamma-ray bursts (GRBs) brought new opportunities for studying the physics of particle acceleration at relativistic shocks. The \hess telescopes recently observed very-high-energy (VHE) emission from a nearby low-luminosity GRB, GRB 190829A. Follow-up observations with, e.g., Swift-XRT, revealed unusual flare activities at $\sim 10^3\rm~s$, which can be caused by a long-lasting central engine. We show that the VHE emission during the H.E.S.S. observation time is naturally produced in the external inverse-Compton (EIC) scenario, where seed photons supplied by the flares or other late-time dissipation are upscattered to VHE energies by the non-thermal electrons accelerated at the external forward shock. Our calculations show that the EIC flare nearly coincides with the late-prompt flare, but extends $\sim3-4$ times longer than the duration of the late-prompt flare. The preferred kinetic energy and initial Lorentz factor used in our model are $\sim 10^{52}\rm~erg$ and $\sim 20$, respectively. Understanding the mechanisms of the VHE emission from low-luminosity GRBs will help us constrain the properties of the outflow and the central engine activities, as well as the particle acceleration mechanism.

description: Private investment in plant breeding has been increasing while public plant breeding has stagnated or declined. Moreover, research investment among crop commodities is uneven. Using a comprehensive survey of U.S. plant breeders from 1994, we use a simultaneous equations model to examine incentives and public-private tradeoffs in plant breeding research among 84 crop commodities. Allocation of private breeders among crops is strongly influenced by market size, hybrid seed technology, and ease of breeding improvement. In general, the allocation of public breeders does not appear to "crowd out" private breeders, but some competition may occur in applied breeding. Public breeding declines as private breeding increases on a commodity. Public breeding is also affected by market size, ease of breeding improvement, and political influence.

The nearly constant mobility for samples with the setback distance larger than 50nm and the similarity between the quantum and transport life-time suggest that the main scattering mechanism is due to short range scattering, such as alloy scattering, with a scattering rate of 2.2 ps$^{-1}$. We also obtain the Fermi level at the In$_{0.53}$Ga$_{0.47}$As/In$_{0.52}$Al$_{0.48}$As surface to be 0.36eV above the conduction band, when fitting our experimental densities with a Poisson-Schrödinger model.

description: In cellular vortical flows, namely arrays of counter-rotating vortices, short but flexible filaments can show simple random walks through their stretch-coil interactions with flow stagnation points. Here, we study the dynamics of semi-rigid filaments long enough to broadly sample the vortical field. Using simulation, we find a surprising variety of long-time transport behavior -- random walks, ballistic transport, and trapping -- depending upon the filament's relative length and effective flexibility. Moreover, we find that filaments execute Lévy walks whose diffusion exponents generally decrease with increasing filament length, until transitioning to Brownian walks. Lyapunov exponents likewise increase with length. Even completely rigid filaments, whose dynamics is finite-dimensional, show a surprising variety of transport states and chaos. Fast filament dispersal is related to an underlying geometry of ``conveyor belts''. Evidence for these various transport states are found in experiments using arrays of counter-rotating rollers, immersed in a fluid and transporting a flexible ribbon.

description: Profitability of using alternative protein sources in broiler feed is investigated through the development of a two-stage mathematical program that optimizes broiler production. A case study of peanut meal vs. soybean meal is examined. Value of marginal product concepts incorporated in this method permit analysis of demand adjustments before decisions on the production process occur. Given reported input and output prices, results indicate that soybean meal is generally more profitable than peanut meal. Peanut meal can be more profitable at higher dietary protein levels fed to broilers processed into whole carcass or at relatively higher prices for soybean meal.

description: Temporally modulated optical media are important in both abstract and applied applications, such as spacetime transformation optics, relativistic laser-plasma interactions, and dynamic metamaterials. Here we investigate the behaviour of temporal boundaries, and show that traditional approaches that assume constant dielectric properties, with loss incorporated as an imaginary part, necessarily lead to unphysical solutions. Further, although physically reasonable predictions can be recovered with a narrowband approximation, we show that appropriate models should use materials with a temporal response and dispersive behaviour.

Analysis of laboratory scale aerated basin using computational techniques
Creators: name: Jenkinson, Robert Wayne
Publisher: name: University of British Columbia
Year: 2009

description: This study endeavored to apply computational fluid dynamics (CFD) techniques to aerated stabilization basins (ASBs) on a laboratory scale. A laboratory study was set up to assess the hydraulic impacts of a small-scale mechanical surface aerator in a still-water tank. A small surface mechanical aerator was built that would circulate from 0.5 to 4 L/sec. The aerator was employed in a tank and the velocity patterns imported by the aerator were measured using an acoustic Doppler velocimeter (ADV). The velocity profiles were converted into dispersion parameters for use in a CFD model. A local turbulent time scale method was used to determine an approximate dispersion value as a function of distance from the aerator. The analysis examined different aerator power settings under otherwise identical conditions. Three successful runs were completed. The chaotic patterns within the tank induced by the aerator, produced turbulent structures that were not easily resolved using a time averaged statistical turbulence approach. Tracer studies were performed in the same basin, modified to provide a flow-through environment. The studies were performed with and without aeration and at different flowthrough rates. Tracer study results were examined and some of the typical parameters used in the literature were extracted for comparative analysis. The trends were surprising as the dimensionless axial dispersion number was inversely related to the degree of mixing applied. A two-dimensional computational fluid dynamics (CFD) model was employed to model the fluid flow within the basin without aeration using a commercial package, FLUENT. The modeling results were compared with depth-averaged ADV velocity measurements taken within the basin. Many CFD modeling parameters were varied, including grid size and structure, turbulence modeling and boundary condition modeling. The model compared well with the ADV data. The results from the FLUENT modeling were applied to a second CFD model that solved the solute transport equations over a structured grid. The solute transport modeling only examined the transport equations with uniform dispersion over the basin and, although it was the original intent, no attempts were made to model aeration at this stage. The overall shape of the modeled tracer curves compared favourably to the tracer study data obtained in the lab.

description: Cash transfer programs induce multiplier effects when recipients put the money they receive to work to generate additional income. The ultimate income effects are multiples of the amounts transferred. This paper analyzes the PROCAMPO program in Mexico, which was introduced to compensate farmers for the anticipated negative effect of the North American Free Trade Agreement (NAFTA) on the price of basic crops. The transfer rules and the timing of the panel data collected allow unique control of biases in this impact analysis. We find that the multiplier among ejido sector recipients is in the range of 1.5 to 2.6. Multipliers are higher for medium and large farm households, low numbers of adults in the household, nonindigenous backgrounds, and households located in the Center and Gulf regions. High multipliers reflect marginal income opportunities that were unrealized due to liquidity constraints that the transfers eased. Opportunities came from the asset endowments that these households have, particularly irrigated land, and these opportunities were enhanced by access to technical assistance.
Low-lying isovector monopole resonances

description: The mass difference between the even-even isobaric nuclei having the valence nucleons on the same degenerate level is attributed to a Josephson-type interaction between pairs of protons and pairs of neutrons. This interaction can be understood as an isospin symmetry-breaking mean field for a four-particle interaction separable in the two particles-two holes channel. The strength of this mean field is estimated within an o(5) algebraic model, by using the experimental value of the inertial parameter for the collective isorotation induced by the breaking of the isospin symmetry. In superfluid nuclei, the presumed interaction between the proton and neutron condensates leads to coupled oscillations of the BCS gauge angles, which should appear in the excitation spectrum as low-lying isovector monopole resonances.

description: Contextuality and nonlocality are non-classical properties exhibited by quantum statistics whose implications profoundly impact both foundations and applications of quantum theory. In this paper we provide some insights into logical contextuality and inequality-free proofs. The former can be understood as the possibility version of contextuality, while the latter refers to proofs of quantum contextuality/nonlocality that are not based on violations of some noncontextuality (or Bell) inequality. The present work aims to build a bridge between these two concepts from what we call possibilistic paradoxes, which are sets of possibilistic conditions whose occurrence implies contextuality/nonlocality. As main result, we demonstrate the existence of possibilistic paradoxes whose occurrence is a necessary and sufficient condition for logical contextuality in a very important class of scenarios. Finally, we discuss some interesting consequences arising from the completeness of these possibilistic paradoxes.

description: Poverty measures and profiles are used increasingly to guide antipoverty policies in low- income countries. An essential element in these analyses is the specification of a poverty line. However, there are many different methods for setting poverty lines, and different methods can yield strikingly different results, with correspondingly different policy implications. Using recent household survey data from Mozambique, this paper explores the differences that occur using the most common poverty line methodologies, the Food Energy Intake (FEI) and the Cost of Basic Needs (CBN) methods, over different levels of geographic specificity. We find that regional and provincial rankings of Foster, Greer, and Thorbecke poverty indices are not robust to the method of poverty line determination, but that the characteristics of the poor are reasonably similar under all methods. The FEI poverty lines often yield counterintuitive results, whereas the family of CBN poverty lines was more robust. Food consumption patterns of the poor show a high degree of substitution among basic staples from one region to another, which is consistent with observed differences in relative food prices, indicating that CBN poverty lines that allow for regional variation in the food consumption bundle may be most appropriate in these settings.

Computer-assisted construction planning

description: The research presented is entitled Computer-Assisted Construction Planning (CACP) and it explores the computer-assisted development of initial comprehensive (include elements of scope, cost, time, performance, and organization) construction plans, which the user can customize to suit a current project. A thorough investigation into the approaches taken for automated construction plan development was performed exploring the methods to capture and reuse planning information and the application of this knowledge to computer-assisted planning. The development of a common database for storage of all project information was completed through the selection and refinements of conceptual core models of several on-going model development projects. Validation of the developed model was performed while populating the developed database with actual project information. An interface for representing the hierarchical breakdown of project information was developed and a Case Based Reasoning approach was selected in light of the required functionality. The research recognizes and follows the path being established for integrated construction management systems that rely on a standard representation of the industry's information requirements. The core information structures were adopted and their validity confirmed by examining a broad application for an integrated system (i.e., planning beyond time and cost). By examining the comprehensive aspects of construction planning within the framework of an integrated construction management system the research demonstrated the usefulness of applying sound information representation structures (i.e., part and type relationships). Through the application of prudent information systems development approaches (i.e., data, process, and interface analyses), and the use of case-based reasoning, the research has advanced the concepts of planning tools as they apply to integrated systems. The research has employed sound information representation principles, explored the implementation of data management tools and techniques, and followed a rigorous development process. The resulting contributions to the research efforts in this area include, in addition to the data model and prototype deliverables, an integrated data model for construction management information, a prototype interface for an integrated construction management system, and a unique approach to assisted planning in support of a practical approach to planning.
Possible origin of 60-K plateau in the YBa2Cu3O(6+y) phase diagram

description: We study a model of YBa2Cu3O(6+y) to investigate the influence of oxygen ordering and doping imbalance on the critical temperature Tc(y) and to elucidate a possible origin of well-known feature of YBCO phase diagram: the 60-K plateau. Focusing on "phase only" description of the high-temperature superconducting system in terms of collective variables we utilize a three-dimensional semi microscopic XY model with two-component vectors that involve phase variables and adjustable parameters representing microscopic phase stiffnesses. The model captures characteristic energy scales present in YBCO and allows for strong anisotropy within basal planes to simulate oxygen ordering. Applying spherical closure relation we have solved the phase XY model with the help of transfer matrix method and calculated Tc for chosen system parameters. Furthermore, we investigate the influence of oxygen ordering and doping imbalance on the shape of YBCO phase diagram. We find it unlikely that oxygen ordering alone can be responsible for the existence of 60-K plateau. Relying on experimental data unveiling that oxygen doping of YBCO may introduce significant charge imbalance between CuO2 planes and other sites, we show that simultaneously the former are underdoped, while the latter -- strongly overdoped almost in the whole region of oxygen doping in which YBCO is superconducting. As a result, while oxygen content is increased, this provides two counter acting factors, which possibly lead to rise of 60K plateau. Additionally, our result can provide an important contribution to understanding of experimental data supporting existence of multicomponent superconductivity in YBCO.

description: There’s more to reading a fiction than meets the eye. Fictions aren’t true: otherwise they wouldn’t be fictions. But it’s true in "Oliver Twist" that Oliver asks for more. It’s certainly not true that Oliver tells lies. It’s true ‒ surely ‒ that Oliver has seen lots of cats. But cats aren’t mentioned in the text. So what’s going on? Evidently, we readers engage in some rather sophisticated language games when we establish the content of a fiction. This thesis investigates some of our games, with special reference to fictions that can interpreted in ways the author hadn’t intended.

description: We use individual observations from a panel of families during the period of the peso crisis in Mexico to investigate whether and how labor market shocks, as proxied by changes in the gender- and age-specific unemployment rates in the metropolitan area of the household, affect the intertemporal time allocation of adult members and children. Our findings suggest that significant added-worker effects are in operation, especially for adult females of poorer households and in some cases children. The same shocks also increase significantly the probability that children do not continue school in the next year. We also present evidence suggesting differential treatment based on the sex of children within families.

description: Recently, the NANOGrav collaboration has reported evidence for a common-spectrum stochastic process, which might be interpreted as the first ever detection of stochastic gravitational wave (GW) background. We discuss the possibility of the signal arising from the first and second-order GWs in nonstandard cosmological history. We show that the NANOGrav observation can be explained by the first order GWs in the nonstandard thermal history with an early matter-dominated era, whereas the parameter space required to explain the NANOGrav observation in the standard cosmology or in the nonstandard epoch of kination domination is ruled out by the BBN and CMB observations. For the second-order GWs arising from the large primordial scalar fluctuations, we study the standard radiation domination and two specific nonstandard cases with a few forms of the primordial power spectrum $P_ζ(k)$ to achieve abundant primordial black hole (PBH) production. We find that the NANOGrav observation can be explained with standard radiation domination for all of these $P_ζ(k)$. Furthermore, a dustlike epoch leads to abundant PBH formation for a lower amplitude of $P_ζ(k)$ than the radiation dominated case and complies with the NANOGrav observation only for a few of the all $P_ζ(k)$ forms considered here, where the peak wavenumber is larger than the wavenumber range probed by the NANOGrav. In this nonstandard epoch, for a broad power spectrum, PBHs are produced in a wide mass range in the planetary mass regime. A nonstandard epoch of kination domination cannot produce enough PBH for any of the $P_ζ(k)$ if the NANOGrav result is to be satisfied.

description: Post-starburst galaxies (PSBs) belong to a short-lived transition population between star-forming (SF) and quiescent galaxies. Deciphering their heavily discussed evolutionary pathways is paramount to understanding galaxy evolution. We aim to determine the dominant mechanisms governing PSB evolution in both the field and in galaxy clusters. Using the cosmological hydrodynamical simulation suite Magneticum Pathfinder, we identify 647 PSBs with $z \sim 0$ stellar mass $M_* \geq 5 \cdot 10^{10} \, \mathrm{M_{\odot}}$. We track their galactic evolution, merger history, and black hole activity over a time-span of 3.6Gyr. Additionally, we study cluster PSBs identified at different redshifts and cluster masses. Independent of environment and redshift, we find that PSBs, like SF galaxies, have frequent mergers. At z=0, 89% of PSBs have experienced mergers and 65% had at least one major merger within the last 2.5Gyr, leading to strong star formation episodes. In fact, 23% of z=0 PSBs were rejuvenated during their starburst. Following the mergers, field PSBs are generally shutdown via a strong increase in AGN feedback (power output $P_{AGN,PSB} \geq 10^{56}\,$erg/Myr). We find agreement with observations for both stellar mass functions and z = 0.9 line-of-sight phase space distributions of PSBs in galaxy clusters. Finally, we find that $z \lesssim 0.5$ cluster PSBs are predominantly infalling, especially in high mass clusters and show no signs of enhanced AGN activity. Thus, we conclude that the majority of cluster PSBs are shutdown via an environmental quenching mechanism such as ram-pressure stripping, while field PSBs are mainly quenched by AGN feedback.

description: We investigate the ground-state phase diagram of the Hubbard model for the AB$_{N-1}$ chain with filling 1/N, where $N$ is the number of atoms per unit cell. In the strong-coupling limit, a charge transition takes place from a band insulator (BI) to a correlated insulator (CI) for increasing on-site repulsion $U$ and positive on-site energy difference $Δ$ (energy at A sites lower than at B sites). In the weak-coupling limit, a bosonization analysis suggests that for $N > 2$ the physics is qualitatively similar to the case $N = 2$ which has already been studied: an intermediate phase emerges, which corresponds to a bond-ordered ferroelectric insulator (FI) with spontaneously broken inversion symmetry. We have determined the quantum phase diagram for the cases $N = 3$ and $N = 4$ from the crossings of energy levels of appropriate excited states, which correspond to jumps in the charge and spin Berry phases, and from the change of sign of the localization parameter $z_{L}^{c}$. From these techniques we find that, quantitatively, the BI and FI phases are broader for $N > 2$ than when $N = 2$, in agreement with the bosonization analysis. Calculations of the Drude weight and $z_{L}^{c}$ indicate that the system is insulating for all parameters, with the possible exception of the boundary between the BI and FI phases.

description: This paper is concerned with the issue of the most cost-effective way of improving access to education for poor households in developing countries. We consider two alternatives: (1) extensive expansion of the school system (i.e., bringing education to the poor) and (2) subsidizing investment in education by the poor (i.e., bringing the poor to the education system). To this end, we evaluate the Programa Nacional de Educación, Salud y Alimentación (PROGRESA), a large poverty alleviation program recently introduced in Mexico that subsidizes education. Using double-difference regression estimators on data collected before and after the program for randomly selected control and treatment households, we estimate the relative impacts of the demand- and supply-side program components. Combining these estimates with cost information, we find that the demand-side subsidies are substantially more cost-effective than supply-side expansions.

description: We study general representations of the free group on two generators into $SL(2,C)$, and the connection with generalized Markoff maps, following Bowditch. We show that Bowditch's Q-conditions for generalized Markoff maps are sufficient for the generalized McShane identity to hold for the corresponding representations and that the subset of representations satisfying these conditions is the largest open subset in the relative character variety on which the mapping class group acts properly discontinuously. Moreover we generalize Bowditch's results on variations of McShane's identity for complete, finite volume hyperbolic 3-manifolds which fiber over the circle, with the fiber a punctured-torus, to identities for incomplete hyperbolic structures on such manifolds, hence obtaining identities for closed hyperbolic 3-manifolds which are obtained by doing hyperbolic Dehn surgery on such manifolds.

description: We study the information paradox for the eternal black hole with charges on a doubly-holographic model in general dimensions, where the charged black hole on a Planck brane is coupled to the baths on the conformal boundaries. In the case of weak tension, the brane can be treated as a probe such that its backreaction to the bulk is negligible. We analytically calculate the entanglement entropy of the radiation and obtain the Page curve with the presence of an island on the brane. For the near-extremal black holes, the growth rate is linear in the temperature. Taking both Dvali-Gabadadze-Porrati term and nonzero tension into account, we obtain the numerical solution with backreaction in four-dimensional spacetime and find the quantum extremal surface at $t=0$. To guarantee that a Page curve can be obtained in general cases, we propose two strategies to impose enough degrees of freedom on the brane such that the black hole information paradox can be properly described by the doubly-holographic setup.

The targum (1952:Feb. 1 - 1952:Feb. 29)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1952

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

On topology optimization of design-dependent pressure-loaded three-dimensional structures and compliant mechanisms

description: This paper presents a density-based topology optimization method for designing three-dimensional (3D) compliant mechanisms and loadbearing structures with design-dependent pressure loading. Instead of interface-tracking techniques, the Darcy law in conjunction with a drainage term is employed to obtain pressure field as a function of the design vector. To ensure continuous transition of pressure loads as the design evolves, the flow coefficient of a finite element is defined using a smooth Heaviside function. The obtained pressure field is converted into consistent nodal loads using a transformation matrix. The presented approach employs the standard finite element formulation and also, allows consistent and computationally inexpensive calculation of load sensitivities using the adjoint-variable method. For compliant mechanism design, a multi-criteria objective is minimized, whereas minimization of compliance is performed for designing loadbearing structures. Efficacy and robustness of the presented approach is demonstrated by designing various pressure-actuated 3D compliant mechanisms and structures.
