description: In this paper, we first characterize reflexive one-sided $\a$-submodules $\u$ of a unital operator algebra $\a$ in $\bh$ completely. Furthermore we investigate the invariant subspace lattice $\lat\r$ and the reflexive hull $\ref\r$, where $\r$ is the submodule generated by rank-one operators in $\u$; in particular, if $ł$ is a subspace lattice, we obtain when the rank-one algebra $\r$ of $\algł$ is big enough to determined $\algł$ in the following senses: $\algł=\alg\lat\r$ and $\algł=\ref\r$.

description: We study the concurrence of arbitrary-dimensional multipartite quantum states. Analytical lower bounds of concurrence for tripartite quantum states are derived by projecting high-dimensional states to $2\otimes 2\otimes 2$ substates. The results are then generalized to arbitrary multipartite quantum systems. Furthermore, the scheme enables us obtain lower bounds of concurrence for arbitrary four-partite quantum states by projecting high-dimensional states to arbitrary given lower dimensional substates. By detailed examples we show that our results improve the existing lower bounds of concurrence.

Invisible to visible : A field study investigating dirty windows and bird-friendly artwork as mitigation strategies against bird-window collisions
Creators: name: Leung, Kelsey
Publisher: name: The University of British Columbia
Year: 2022

description: Estimates suggest that 16 to 43 million bird deaths occur annually due to collisions with buildings in Canada. Buildings on the University of British Columbia Vancouver campus may contribute up to 10,000 bird deaths each year. The reflective and transparent properties of glass, combined with birds having poor spatial acuity in the direction of motion, make it challenging for birds to perceive glass as a solid barrier, resulting in bird-window collisions. This study investigates the effect of two mitigation strategies employed by the UBC Botanical Garden: reducing window washing frequency, which allows dirt to accumulate on windows and the installation of bird-friendly artwork. A comparison of collision frequency over an 8-week monitoring period in late winter and early spring of 2021 and 2022 is used to investigate the effectiveness of these strategies. A 97% decrease in collision evidence was reported from 2021 to 2022, suggesting that dirty windows and bird-friendly artwork are effective at reducing birdwindow collisions. We recommend that both strategies should be implemented at other buildings on the UBC campus and suggested to businesses and homeowners to reduce the negative impact windows have on bird populations. Further studies should be conducted on the effect of dirty windows, as limited research directly investigates this strategy. Additionally, a comparison between the effectiveness of dirty windows, bird-friendly artwork, and other mitigation strategies (such as decals or ultraviolet film application) should be conducted to determine which offers the highest level of protection against bird-window collisions. Future research should also investigate social aspects of bird-window collisions, including public perception and awareness, in order to improve mitigation strategies and better understand barriers to their implementation.

description: We study spin relaxation and decoherence in a GaAs quantum dot due to spin-orbit interaction. We derive an effective Hamiltonian which couples the electron spin to phonons or any other fluctuation of the dot potential. We show that the spin decoherence time $T_2$ is as large as the spin relaxation time $T_1$, under realistic conditions. For the Dresselhaus and Rashba spin-orbit couplings, we find that, in leading order, the effective magnetic field can have only fluctuations transverse to the applied magnetic field. As a result, $T_2=2T_1$ for arbitrarily large Zeeman splittings, in contrast to the naively expected case $T_2\ll T_1$. We show that the spin decay is drastically suppressed for certain magnetic field directions and values of the Rashba coupling constant. Finally, for the spin coupling to acoustic phonons, we show that $T_2=2T_1$ for all spin-orbit mechanisms in leading order in the electron-phonon interaction.

description: Previous research suggests that early experience of and exposure to the world of work is an important predictor of a child’s future involvement in a STEM career. Many interventions have focused on those in secondary education age 11 years and above. Far fewer interventions have explored the impact of STEM outreach engagements among younger age groups. This study investigates the impact of a project that delivered career-driven STEM interventions on young children’s (7–10 years old) career knowledge and perceptions over time. Using an action research approach, this study outlines 10 distinct features for designing child-centred STEM interventions. These were delivered in 6 primary schools across North-East England over a 2-year period. A STEM Career Knowledge and Aspirations Tool was used to collect data to evaluate the impact of these interventions. Children sorted 30 job cards (mix of STEM and non-STEM) into jobs they knew, and also into jobs they would like to do. Baseline data and follow up data were collected in 2015 (n = 352) and 2017 (n = 356). Data analysis suggests the sustained interventions had a particularly positive effect on girls. In 2015 prior to the interventions, girls were significantly less likely than boys to know the following STEM jobs: surveyor, technician and game tester. In 2017, following the sustained intervention, there was no significant difference between boys and girls. Furthermore, one of the STEM jobs, Engineer, showed the greatest increase in the percentage of boys and girls that wanted to do it in 2017 compared to 2015.

description: A stability problem for the current state of the strong coupling superconductor has been considered within the lattice Ginzburg-Landau model. The critical current problem for a thin superconductor film is solved within the London limit taking into account the crystal lattice symmetry. The current dependence on the order parameter modulus is computed for the superconductor film for various coupling parameter magnitudes. The field penetration problem is shown to be described in this case by the one-dimensional sine-Gordon equation. The field distribution around the vortex is described at the same time by the two-dimensional elliptic sine-Gordon equation.

description: Economic problems and a severe drought negatively affected Sudan, a largely agricultural country. Prior to the drought, the Government enacted a series of policy reforms to improve agricultural productivity and increase exports, including adjustments in exchange rates, higher producer prices, institutional changes in the irrigated subsector, and reduction of consumer subsidies on wheat bread, petroleum products, and sugar. The structural diversity of Sudan's agricultural sector in terms of locus of decisionmaking, input and output price determination, and use of imported inputs, however, worked against across-the-board reform. The severity of the drought also blunted the effects of policy changes--reducing agricultural production, increasing food dependency on foreign suppliers, and causing massive population dislocation. After the drought, policy options remaining open to the Government focus on achieving higher export earnings and a greater degree of food self-sufficiency.

description: We propose schemes for efficiently destroying privacy data in a NAND flash memory. Generally, even if privcy data is discarded from NAND flash memories, there is a high probability that the data will remain in an invalid block. This is a management problem that arises from the specificity of a program operation and an erase operation of NAND flash memories. When updating pages or performing a garbage collection, there is a problem that valid data remains in at least one unmapped memory block. Is it possible to apply the obligation to delete privacy data from existing NAND flash memory? This paper is the answer to this question. We propose a partial overwriting scheme, a SLC programming scheme, and a deletion duty pulse application scheme for invalid pages to effectively solve privacy data destruction issues due to the remaining data. Such privacy data destruction schemes basically utilize at least one state in which data can be written to the programmed cells based on a multi-level cell program operation. Our privacy data destruction schemes have advantages in terms of block management as compared with conventional erase schemes, and are very economical in terms of time and cost. The proposed privacy data destruction schemes can be easily applied to many storage devices and data centers using NAND flash memories.

Long-time dynamics of Rouse-Zimm polymers in dilute solutions with hydrodynamic memory

description: The dynamics of flexible polymers in dilute solutions is studied taking into account the hydrodynamic memory, as a consequence of fluid inertia. As distinct from the Rouse-Zimm (RZ) theory, the Boussinesq friction force acts on the monomers (beads) instead of the Stokes force, and the motion of the solvent is governed by the nonstationary Navier-Stokes equations. The obtained generalized RZ equation is solved approximately. It is shown that the time correlation functions describing the polymer motion essentially differ from those in the RZ model. The mean-square displacement (MSD) of the polymer coil is at short times \~ t^2 (instead of ~ t). At long times the MSD contains additional (to the Einstein term) contributions, the leading of which is ~ t^(1/2). The relaxation of the internal normal modes of the polymer differs from the traditional exponential decay. It is displayed in the long-time tails of their correlation functions, the longest-lived being ~ t^(-3/2) in the Rouse limit and t^(-5/2) in the Zimm case, when the hydrodynamic interaction is strong. It is discussed that the found peculiarities, in particular an effectively slower diffusion of the polymer coil, should be observable in dynamic scattering experiments.

description: Domestic population growth and greater use of processed eggs over the past three decades offset the decline in per-capita shell egg use and left total egg consumption for domestic food purposes averaging about 5 billion dozen a year. This paper analyzes effects of prices, income, and household characteristics on the demand for eggs. Evidence from a complete demand system indicates that eggs are more price inelastic than either red meat or poultry. The own-price elasticity for eggs was found to be -0.1429. The income elasticity for eggs, derived from an analysis of the 1977-78 USDA Nationwide Food Consumption Survey, was estimated to be approximately -0.05. Region of household residence, season, race, age, and household size also influence egg consumption and expenditures.

description: Japanese grain yields, areas, production, food demand, feed demand, trade, and government pricing policies are modeled on the basis of data mostly from 1965-79. Grains are classified into rice, wheat, corn, and other coarse grains, with the last often subdivided into barley and other grain. The model is then simulated through 1992, using as exogenous variables projections of Japanese population, Japanese real income, and U.S. grain prices (as proxies for world trade prices). The model's equations are designed for making 5- to 20-year projections, but alternative equations more suited to short-run policy analysis are also presented.
title: The reorganisation of the National Health Service, 1965-74.
Creators: name: Brewer, Robert Charles
Publisher: name: The Open University
Year: 1980

description: This is a case study of the development of plans for an administrative reorganisation and the part played in that process by interest groups and government departments. It is argued that changes in the context in which the NHS operated in terms of demography, epidemiology, social philosophy and administrative concepts as well as problems of cost and co-ordination had made adjustments to its structure desirable, and that proposed changes in the structure of local government and its social services crystallised this need. The reparation of medical and social work skills in the field by the implementation of the Geebohm Report made a fundamental review of the NHS structure necessary as it involved a shift in cost burdens from local to central government which invited questions concerning administrative supervision from the centre and political questions concerning the future of the medical officers of health. It is argued that the reorganisation involved questions of both vertical control and lateral co-ordination. The former was determined by the desire of the Treasury for a greater degree of management accountability and of the Central Department for improved control and implementation of policy decisions, which meant that few concessions were made to interest groups which might hinder the attainment of these objectives. Interest groups were more influential in determining the character of proposals concerned with lateral co-ordination, and here the pattern indicated by Willcocks in his study of the creation of the NHS is found to be repeated, with groups commanding resources based on technical expertise (the medical profession) found in varying degrees to be more influential than those commanding administrative expertise (local government).

description: This paper identifies U.S. counties where farming remains a major part of the economic base. Both farm employment and farm income are used to measure a county's reliance on farming. Counties that rely on farming are located principally in the Plains and western Corn Belt regions. Since roughly two-thirds of the counties defined as farm reliant using one indicator are so defined using the other indicator, there is a large area of overlap and similarity between the two groups. Although employment and income indicators define somewhat different groups of counties as farm reliant, both identify counties where overall job growth has lagged, and consequently, where there is a need for economic diversification if population levels are to be sustained.

description: Photon pair generation in silicon photonic integrated circuits relies on four wave mixing via the third order nonlinearity. Due to phase matching requirements and group velocity dispersion, this method has typically required TE polarized light. Here, we demonstrate TM polarized photon pair production in linearly uncoupled silicon resonators with more than an order of magnitude more dispersion than previous work. We achieve measured rates above 2.8 kHz and a heralded second order correlation of $g^{(2)}(0) = 0.0442 \pm 0.0042$. This method enables phase matching in dispersive media and paves the way for novel entanglement generation in silicon photonic devices.

description: Egypt relies on wheat imports for more than half of its consumption. Future imports are likely to rise because of the limited arable land and already very high yields. The three largest suppliers of wheat in the Egypt market are the United States, Australia, and the European Community. The wheat import market in Egypt is highly competitive. The types of export promotion programs, in particular the prices offered, will determine the market shares. Providing cleaner wheat will not change the shares. However, providing consistent quality could expand the U.S. share. U.S. white wheat has the best potential to capture a larger share of the market.

description: The expression for the force on an ion in the presence of current can be derived from first principles without any assumption about its conservative character. However, energy functionals have been constructed that indicate that this force can be written as the derivative of a potential function. On the other hand, there exist compelling specific arguments that strongly suggest the contrary. We propose physical mechanisms that invalidate such arguments and demonstrate their existence with first-principles calculations. While our results do not constitute a formal resolution to the fundamental question of whether current-induced forces are conservative, they represent a substantial step forward in this direction.

description: We study electron transport in two-dimensional materials with parabolic and linear (graphene) dispersions of the carriers in the presence of surface acoustic waves and an external magnetic field using semiclassical Boltzmann equations approach. We observe an oscillatory behavior of both the longitudinal and Hall electric currents as functions of the surface acoustic wave frequency at a fixed magnetic field and as functions of the inverse magnetic field at a fixed frequency of the acoustic wave. We explain the former by the phenomenon of geometric resonances, while we relate the latter to the Weiss-like oscillations in the presence of the dynamic superlattice created by the acoustic wave. Thus we demonstrate the dual nature of the acoustomagnetoelectric effect in two-dimensional electron gas.

description: Our experiments and molecular dynamics simulations on a projectile penetrating a two-dimensional granular medium reveal that the mean deceleration of the projectile is constant and proportional to the impact velocity. Thus, the time taken for a projectile to decelerate to a stop is independent of its impact velocity. The simulations show that the probability distribution function of forces on grains is time-independent during a projectile's penetration of the medium. At all times the force distribution function decreases exponentially for large forces.

description: Indonesia does not produce wheat, and imports have risen rapidly. However, U.S. wheat exports to Indonesia fell from 850,000 metric tons in 1983 to near zero in 1991. This was due to Australian transport and price advantages in the Indonesian soft wheat market and the entry of several new exporters in the market for hard wheat. Canadian exports have also risen in recent years. The Indonesian market for wheat and wheat flour is highly regulated. As a result, the quality needs of flour users are not reflected in market signals. This limits the role of quality in import decisions. Indonesian millers complain about dockage in U.S. wheat because of its effect on milling rates and profits. However, Indonesia would not pay a premium for cleaner U.S. wheat. Given the price discounts currently offered by competitors, it is unlikely that Indonesia would purchase more U.S. wheat if it were cleaner.

description: This study aimed to determine how labels containing different levels of information about “ugly produce” impacted UBC students’ food purchase choices. We hypothesized that labels with the term “ugly produce” along with the description of the term, would be a more popular choice compared to labels with just the term, or labels with neither the term nor the description. A between-group research study was conducted, where 89 participants who were all UBC students were exposed to one of 3 conditions: food label with neither the term “ugly produce” nor the description, with the term “ugly produce” and no description, and with the term “ugly produce” and a description of the term. We controlled for participants’ year of study, love for consuming meat, price consciousness, and environmental consciousness. Our results supported our hypothesis. We also found a correlation between environmental consciousness and the likelihood of purchasing a dish in each condition. Based on our results, we recommend that if UBC Food Services chooses to use the term “ugly produce” on their Food Labels, they should also include a description of the term and target students who consider themselves environmentally conscious. Overall, these actions will help UBC reach its sustainability goals.

description: We study theoretically proximity-induced superconductivity and its inverse effect in dice lattice flat band model by considering Josephson junction with an s-wave pairing in the superconducting leads. Using self-consistent tight-binding Bogoliubov-de Gennes method, we show that there is a critical value for chemical potential of the superconductors depending on paring interaction strength over which for undoped normal region the proximity effect is enhanced. Whereas if the superconductor chemical potential is less than the critical one the proximity effect decreases regardless of normal region doping and in the meanwhile, the pairing amplitude of superconducting region increases significantly. Furthermore, we unveil that the supercurrent passing through the junction is large (vanishingly small) when the superconductor chemical potential is smaller (larger) than the critical value which increases as a function of normal region chemical potential.

Genetic programming approaches to learning fair classifiers

description: Society has come to rely on algorithms like classifiers for important decision making, giving rise to the need for ethical guarantees such as fairness. Fairness is typically defined by asking that some statistic of a classifier be approximately equal over protected groups within a population. In this paper, current approaches to fairness are discussed and used to motivate algorithmic proposals that incorporate fairness into genetic programming for classification. We propose two ideas. The first is to incorporate a fairness objective into multi-objective optimization. The second is to adapt lexicase selection to define cases dynamically over intersections of protected groups. We describe why lexicase selection is well suited to pressure models to perform well across the potentially infinitely many subgroups over which fairness is desired. We use a recent genetic programming approach to construct models on four datasets for which fairness constraints are necessary, and empirically compare performance to prior methods utilizing game-theoretic solutions. Methods are assessed based on their ability to generate trade-offs of subgroup fairness and accuracy that are Pareto optimal. The result show that genetic programming methods in general, and random search in particular, are well suited to this task.

description: The relevance of this topic is due to the fact that in modern conditions, income inequality can reach enormous proportions and pose a threat to political and economic stability in the country, exacerbated by the impact of the pandemic, because the standard of living of the population depends on them. According to forecasts, the poverty rate in the country due to the pandemic will increase from 27.2% to 43.6%, and in the worst case up to 50.8% of the total population. We recorded a sharp increase in poverty in the first quarter of 2020. In the first half of the year, the poverty rate rose to 51%. In the first half of 2019, 41% of Ukrainians were poor. The poverty rate in 2020 will be 45-50%. Despite the state's efforts to help people who have lost their jobs, the average nominal amount of unemployment benefits in 2020 has decreased even in hryvnia equivalent. According to the State Employment Center, in JanuaryNovember by UAH 309. In dollar terms from $ 164 to $ 126 per month. The current situation in the field of income in Ukraine is characterized by a large accumulation of social tensions, which can be reduced by creating conditions for proper quality of life. The official assessment of inequality in Ukraine does not reflect the real state of affairs, insofar as it does not take into account undeclared cash income, the informal economy and informal income. Namely, informal employment is a significant source of income and consumption for a large part of the population. The deepening of social stratification is also influenced by the lack of state efforts to reduce social inequality.

description: The article proves that the existing version of the special theory of relativity (STR), based on the postulated principle of non-exceeding the speed of light, is incorrect. Therefore, an alternative version of STR, based on the experimentally proven principle of the physical reality of imaginary numbers, is proposed. And from the alternative version of STR follows the existence of invisible universes with their own super-civilizations. Therefore, attempts to establish contacts with extraterrestrial super-civilizations of our visible universe as a result of flights to the Moon and Mars or as a result of the detection of their activity in other star systems thousands of light years from Earth are unnecessary, since the inhabitants of super-civilizations are also on Earth. They even send us messages, for example in the form of so-called ‘crop circles’. But since we were not intellectually advanced enough to read these messages, our human civilization did not interest them. And any of our contacts with them, apart from their desire, are impossible. Therefore, the way out of this situation is to transform the existing human civilization into super-civilization through the creation and use of human-computer super-intelligence.

description: Italy imports wheat from outside the European Community due t the demand for the highest quality wheat available. The protection afforded by the EC's variable levy results in U.S. and Canadian wheat costing 50 percent more in the Italian market than domestic EC wheat. However, U.S. and Canadian wheats have intrinsic characteristics which meet the exact requirements for certain purposes. These include high protein, appropriate color (for durum wheat), and, most important, a wide range of gluten performance standards. Italian importers pay not only the wheat price for the weight of any impurities in the shipment, they also must pay insurance and freight, as well as the variable levy. Thus dockage is considered an economic factor in their purchasing decisions, rather than a technical impediment in the milling process. Dockage and foreign material are less important to Italian traders and millers when the protein and gluten are satisfactory, that is, when their customers are pleased with the performance quality of the product.
