subject: Questionnaire

description: Community leaders in a study of eight watersheds ranked education ahead of health, roads, and streets, and erosion and flood control as the most valuable public service categories of community development. Under the water resource categories, respondents rated water channel development first in importance and land treatment second. More than 98 percent of the leaders favored the Small Watershed Program. Suggested changes in the program were to reduce the time needed to plan and install projects, build structures to physical capacity, emphasize other uses of water, and assure public access to reservoirs.
An affine version of a theorem of Nagata
Creators: name: Freudenburg, Gene

Subjects: subject: Commutative Algebra (math.AC)

subject: 13B25, 14R20

description: Let R be an affine k-domain over the field k. The paper's main result is that, if R admits a non-trivial embedding in a polynomial ring K[s] for some field K containing k, then R can be embedded in a polynomial ring F[t] which extends R algebraically. This theorem can be applied to subrings of a ring which admits a non-zero locally nilpotent derivation. In this way, we obtain a concise new proof of the cancellation theorem for rings of transcendence degree one for fields of characteristic zero.

Development of machine learning-based intelligent COVID-19 contact tracing tools
Creators: Kosasih, Wilson
Publisher: name: University of Alberta Library
Year: 2022

With the easing of COVID-19 regulations in Alberta, people are gradually back to their normal life. However, we cannot be careless, since there is a possibility for a new variant. The technology could help to prevent the further spread of the pandemic. In addition, in terms of contact tracing, most people’s concerns are about privacy and security, where people’s data tend to be tracked and used without their consent. The proposed COVID-19 contact tracing method uses the clustering method, one type of machine learning algorithm that is used to segregate the data into different groups based on their characteristics. In this research, different types of clustering algorithms, Density-based Clustering (clusters are formed based on the density of the region) and Hierarchical-based Clustering (clusters are formed using hierarchy structure), and K-Means Clustering (clusters where the preset clusters are set. Besides the algorithms mentioned before, we will also compare Epidemic Modeling, Agent-Based

Modeling, and Exposure Notification. They are used and a comparative study has been conducted on these algorithms in terms of efficiency and privacy. This research would not only be useful to trace potential infections of COVID-19, but it would also, build a process to suppress the spread. In the future, we would like to develop a hybrid model to enhance the efficacy of the tools further in terms of both accuracy and security by exploring more sophisticated Machine Learning (ML) techniques, and it could be useful for other infectious diseases as well.

description: During 1960-72, the retail price of refined sugar increased 22 percent, while the farmer’s share of the consumer's dollar increased from 36 to 42 percent. Returns to sugarbeet and sugarcane growers in all domestic production areas increased. This increase ranged from 1.37 cents per pound in Florida to 1.74 cents per pound in the Central sugarbeet region. The refiner's share of the marketing spread increased in all areas. The distribution and retailers' share of the marketing spread decreased, in some instances as much as 2 cents per pound. This report is based on information on the farm-to-retail spread for sugar in 25 major U.S. cities between 1960-72.

An efficient method for evaluating energy-dependent sum rules

description: Energy-dependent sum rules are useful tools in many fields of physics. In nuclear physics, they typically involve an integration of the response function over the nuclear spectrum with a weight function composed of integer powers of the energy. More complicated weight functions are also encountered, e.g., in nuclear polarization corrections of atomic spectra. Using the Lorentz integral transform method and the Lanczos algorithm, we derive a computationally efficient technique for evaluating such sum rules that avoids the explicit calculation of both the continuum states and the response function itself. Our numerical results for electric dipole sum rules of the Helium-4 nucleus with various energy-dependent weights show rapid convergence with respect to the number of Lanczos steps. This demonstrates the usefulness of the method in a variety of electroweak reactions.

We succeeded to find solutions for a large class of string configurations on this background. In particular, we derive dyonic giant magnon solutions in the R_t x S^3 subspace, and obtain the leading finite-size correction to the dispersion relation.

Fitness trackers can help improve physical activity, and thereby reduce the risksof diseases such as diabetes, obesity, as well as hypertension. Despite these health related benefits, the way these devices are being used by the end user, play a crucial role for the persistent success of fitness trackers. To understand how these factors influence continuous use of fitness trackers and investigate the particular role of health and wellness improvement, this case study has analysed public domain fitness tracker data. Based on a rigorous iterative thematic data analysis, where the emphasis has been on matching deep diving with data and literature, a thematic framework has been developed and it identifies the prominent determinants. The findings propose new innovative ways through which these products and its ecosystem can be improved and how these devices can be marketed more efficiently. This case study will help researchers and academics to uncover as well as visualise user perceptions concerning fitness trackers and also provide practitioners with workable suggestions for ensuring

their continuous use.

Flare in the Galactic stellar outer disc detected in SDSS-SEGUE data

Year: 2014
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Aims. We explore the outer Galactic disc up to a Galactocentric distance of 30 kpc to derive its parameters and measure the magnitude of its flare. Methods. We obtained the 3D density of stars of type F8V-G5V with a colour selection from extinction-corrected photometric data of the Sloan Digital Sky Survey - Sloan Extension for Galactic Understanding and Exploration (SDSS-SEGUE) over 1,400 deg^2 in off-plane low Galactic latitude regions and fitted it to a model of flared thin+thick disc. Results. The best-fit parameters are a thin-disc scale length of 2.0 kpc, a thin-disc scale height at solar Galactocentric distance of 0.24 kpc, a thick-disc scale length of 2.5 kpc, and a thick-disc scale height at solar Galactocentric distance of 0.71 kpc. We derive a flaring in both discs that causes the scale height of the average disc to be multiplied with respect to the solar neighbourhood value by a factor of 3.3^{+2.2}_{-1.6} at R=15 kpc and by a factor of 12^{+20}_{-7} at R=25 kpc. Conclusions. The flare is quite prominent at large R and its presence explains the apparent depletion of in-plane stars that are often confused with a cut-off at R>15 kpc. Indeed, our Galactic disc does not present a truncation or abrupt fall-off there, but the stars are spread in off-plane regions, even at z of several kpc for R>20 kpc. Moreover, the smoothness of the observed stellar distribution also suggests that there is a continuous structure and not a combination of a Galactic disc plus some other substructure or extragalactic component: the hypothesis to interpret the Monoceros ring in terms of a tidal stream of a putative accreted dwarf galaxy is not only unnecessary because the observed flare explains the overdensity in the Monoceros ring observed in SDSS fields, but it appears to be inappropriate.

description: Records from several sources revealed that 228 of 742 persons completing a Title III-B Economic Opportunity Act job training program during 1967-71 had obtained employment. Of the 228, a sample of 104 was located and interviewed, with 74 (46 blacks, 28 whites) still employed in 1971, and with 29 (9 whites, 20 blacks) who had previously been employed being unemployed in 1971. The main roadblocks to jobs during the year ending July 1971 were "could not find suitable work," and "laid off from work." Reasons for leaving their first job after III-B training also centered on being laid off from work (32 percent), but included transportation problems (15 percent). In addition to these 104 respondents, a random sample of 30 persons (2 whites, 28 blacks) was used to represent the remaining 514 trainees who had failed to obtain employment. This last group of 30 tended to be black, unmarried, separated, or divorced females with children. They had experienced unemployment during the year ending July 1971 mainly because of inability to find suitable work (70 percent), and ill health (13 percent).

description: We investigate the resonant cooling phenomena of a driven two-level radiator embedded in a photonic crystal structure. We find that cooling occurs even at laser-atom-frequency resonance. This happens due to the atomic dressed-states coupling with different strengths resulting in population redistribution and cooling. Furthermore, for off-resonant driving the two-level particle can be in either ground or excited bare-state, respectively. This may help in engineering of novel amplified optical devices as well as highly coherent light sources.

description: We introduce a superconducting qubit architecture that combines high-coherence qubits and tunable qubit-qubit coupling. With the ability to set the coupling to zero, we demonstrate that this architecture is protected from the frequency crowding problems that arise from fixed coupling. More importantly, the coupling can be tuned dynamically with nanosecond resolution, making this architecture a versatile platform with applications ranging from quantum logic gates to quantum simulation. We illustrate the advantages of dynamic coupling by implementing a novel adiabatic controlled-Z gate, at a speed approaching that of single-qubit gates. Integrating coherence and scalable control, our "gmon" architecture is a promising path towards large-scale quantum computation and simulation.

description: In the Standard Model the Higgs coupling to gluons is almost entirely induced by top quark loops. We derive the logarithmic structure of Higgs production in association with two jets. Just like in the one-jet case the transverse momentum distributions exhibit logarithms of the top quark mass and can be used to test the nature of the loop-induced Higgs coupling to gluons. Using Higgs decays to W bosons and to tau leptons we show how the corresponding analyses hugely benefit from the second jet in the relevant signal rate as well as in the background rejection.

description: We consider renormalizable theories such that the scattering of dark matter off leptons arises at tree level, but scattering off nuclei only arises at loop. In this framework, the various dark matter candidates can be classified by their spins and by the forms of their interactions with leptons. We determine the corrections to the anomalous magnetic moment of the muon that arise from these interactions. We then consider the implications of these results for a set of simplified models of leptophilic dark matter. When a dark matter candidate reduces the existing tension between the standard model prediction of the anomalous magnetic moment and the experimental measurement, the region of parameter space favored to completely remove the discrepancy is highlighted. Conversely, when agreement is worsened, we place limits on the parameters of the corresponding simplified model. These bounds and favored regions are compared against the experimental constraints on the simplified model from direct detection and from collider searches. Although these constraints are severe, we find there do exist limited regions of parameter space in these simple theories that can explain the observed anomaly in the muon magnetic moment while remaining consistent with all experimental bounds.

description: After more than two decades of agricultural surpluses and Federal supply management programs, strong demand for food products in 1973 resulted in suspension of the Federal land set-aside programs. By 1974, virtually all acreage formerly diverted had been released and most good quality, readily usable acreage was brought back into production. This study summarizes recent changes in cropland use and evaluates additional land, mainly pasture and forest, that could be converted to crop production. But several factors will likely retard the rate of development of new land. These include size of tract, ownership patterns, ease and scale of development, crop alternatives, and competition from other uses. Existing and potential cropland are discussed within a regional context.

description: An efficient $λ/2$-method ($λ$ is the resonant wavelength of laser radiation) based on nanometric-thickness cell filled with rubidium is implemented to study the splitting of hyperfine transitions of $^{85}$Rb and $^{87}$Rb $D_2$ lines in an external magnetic field in the range of $B =3$~kG -- 7~kG. It is experimentally demonstrated that at $B > 3$~kG from 38 (22) Zeeman transitions allowed at low $B$-field in $^{85}$Rb ($^{87}$Rb) spectra in the case of $σ^+$ polarized laser radiation there remain only 12 (8) which is caused by decoupling of the total electronic momentum $\textbf{J}$ and the nuclear spin momentum $\textbf{I}$ (hyperfine Paschen-Back regime). Note that at $B > 4.5$~kG in the absorption spectrum these $20$ atomic transitions are regrouped in two completely separate groups of $10$ atomic transitions each. Their frequency positions and fixed (within each group) frequency slopes, as well as the probability characteristics are determined. A unique behavior of the atomic transitions of $^{85}$Rb and $^{87}$Rb labeled $19$ and $20$ (for low magnetic field they could be presented as transitions $F_g=3, m_F=+3 \rightarrow F_e=4, m_F=+4$ and $F_g=2, m_F=+2 \rightarrow F_e=3, m_F=+3$, correspondingly) is stressed. The experiment agrees well with the theory. Comparison of the behavior of atomic transitions for $D_2$ line compared with that of $D_1$ line is presented. Possible applications are described.

Chi ha detto che gli aloni di materia oscura debbano essere sferici? Secondo i calcoli di un gruppo di astronomi dell'Harvard-Smithsonian Center for Astrophysics, l'alone di materia oscura che circonda la Via Lattea potrebbe avere una forma oblunga, simile a quella di un dirigibile o di un pallone da rugby. Questo spiegherebbe la deformazione del disco di stelle della nostra galassia. I dettagli su Nature Astronomy

description: We present an analysis of seven intense X-ray flares observed from six stars (LAV 796, LAV 1174, SHM2002 3734, 2MASS 02191082+5707324, V553 Car, V557 Car) for the first time. These stars are located in the region of young open star clusters NGC 869 and IC 2602. These flares detected in the XMM-Newton data show a rapid rise (10-40 minutes) and a slow decay (20-90 minutes). The X-ray luminosities during the flares in the energy band 0.3-7.5 keV are in the range of $10^{29.9}$ to $10^{31.7}$ erg s$^{-1}$. The strongest flare was observed with the ratio $\sim 13$ for count rates at peak of the flare to the quiescent intensity. The maximum temperature during the flares has been found to be $\sim$100 MK. The semi loop lengths for the flaring loops are estimated to be of the order of $\rm{10^{10}}$ cm. The physical parameters of the flaring structure, the peak density, pressure, and minimum magnetic field required to confine the plasma have been derived and found to be consistent with flares from pre-main sequence stars in the Orion and the Taurus-Auriga-Perseus region.

Combinando dati d’archivio ottenuti da vari telescopi nell’arco di due decenni, un team internazionale di astronomi guidato dall'Università di Colonia ha studiato in dettaglio Irs 13, un ammasso stellare al centro della Galassia. Lo studio ha mostrato un numero elevato di stelle nelle fasi iniziali dell'evoluzione. Un risultato, questo, difficilmente spiegabile con le attuali teorie di formazione stellare se si considera la prossimità dell'ammasso al "nostro" buco nero

description: We investigate the anisotropy of the optical properties of thin Fe films on GaAs(001) from first-principles calculations. Both intrinsic and magnetization-induced anisotropy are covered by studying the system in the presence of spin-orbit coupling and external magnetic fields. We use the linearized augmented plane wave method, as implemented in the WIEN2k density functional theory code, to show that the $C_{2v}$ symmetric anisotropy of the spin-orbit coupling fields at the Fe/GaAs(001) interface manifests itself in the corresponding anisotropy of the optical conductivity and the polar magneto-optical Kerr effect. While their magnetization-induced anisotropy is negligible, the intrinsic anisotropy of the optical properties is significant and reflects the underlying $C_{2v}$ symmetry of the Fe/GaAs(001) interface. This suggests that the effects of anisotropic spin-orbit coupling fields in experimentally relevant Fe/GaAs(001) slabs can be studied by purely optical means.

Venere potrebbe essere un luogo leggermente più mite di quanto si pensi. In una nuova ricerca, i fisici della Cu Boulder si sono addentrati nel dibattito di lunga data sulla presenza o meno di fulmini sul gemello della Terra. Basandosi sulle osservazioni di Parker Solar Probe delle cosiddette whistler waves, onde radio a bassa frequenza, sono arrivati a concludere che probabilmente su Venere non ci sono fulmini

If I Could Talk to the Animals: Measuring Subjective Animal Welfare
Creators: name: Browning, Heather
Publisher: name: The Australian National University
Year: 2020

description: Animal welfare is a concept that plays a role within both our moral deliberations and the relevant areas of science. The study of animal welfare has impacts on decisions made by legislators, producers and consumers with regards to housing and treatment of animals. Our ethical deliberations in these domains need to consider our impact on animals, and the study of animal welfare provides the information that allows us to make informed decisions. This thesis focusses on taking a philosophical perspective to answer the question of how we can measure the welfare of animals. Animal welfare science is an applied area of biology, aimed at measuring animal welfare. Although philosophy of animal ethics is common, philosophy focussing on animal welfare science is rare. Despite this lack, there are definitely many ways in which philosophical methods can be used to analyse the methodologies and concepts used in this science. One of the aims of the work in this thesis is to remedy this lack of attention in animal welfare. Animal welfare science is a strong emerging discipline, but there is the need for conceptual and methodological clarity and sophistication in this science if it is to play the relevant informative role for our practical and ethical decision-making. There is thus is a strong role here for philosophical analysis for this purpose. The central aim of this thesis is to provide an account of how we can measure subjective animal welfare, addressing some of the potential problems that may arise in this particular scientific endeavour. The two questions I will be answering are: what is animal welfare, and how do we measure it? Part One of the thesis looks at the subjective concept of animal welfare and its applications. In it, I argue for a subjective welfare view - that animal welfare should be understood as the subjective experience of individuals over their lifetimes - and look at how the subjective welfare concept informs our ethical decision-making in two different cases in applied animal ethics. Part Two of the thesis looks more closely at the scientific role of welfare. Understanding welfare subjectively creates unique measurement problems, due to the necessarily private nature of mental states and here I address a few of these problems, including whether subjective experience is measurable, how we might validate indicators of hidden target variables such as welfare, how we can make welfare comparisons between individual animals and how we might compare or integrate the different types of experience that make up welfare. I end with a discussion of the implications of all these problems and solutions for the practice of welfare science, and indicate useful future directions for research.

Giant thermoelectric effects in a proximity-coupled superconductor-ferromagnet device

description: The usually negligibly small thermoelectric effects in superconducting heterostructures can be boosted dramatically due to the simultaneous effect of spin splitting and spin filtering. Building on an idea of our earlier work [Phys. Rev. Lett. $\textbf{110}$, 047002 (2013)], we propose realistic mesoscopic setups to observe thermoelectric effects in superconductor heterostructures with ferromagnetic interfaces or terminals. We focus on the Seebeck effect being a direct measure of the local thermoelectric response and find that a thermopower of the order of $\sim200$ $μV/K$ can be achieved in a transistor-like structure, in which a third terminal allows to drain the thermal current. A measurement of the thermopower can furthermore be used to determine quantitatively the spin-dependent interface parameters that induce the spin splitting. For applications in nanoscale cooling we discuss the figure of merit for which we find enormous values exceeding 1 for temperature $\lesssim 1$K.
