Mutual-Friction Coefficients in Two-Dimensional Superfluids: From the Gross-Pitaevskii equation to the Hall-Vinen-Bekharevich-Khalatnikov Two-fluid Model
No full textWe start from the two-dimensional Gross-Pitaevskii equation (GPE) and develop algorithms for the ab-initio determination of the temperature (T) dependence of the mutual-friction coefficients, α and α, and the normal-fluid density Pn, which appear as parameters in the Hall-Vinen-Bekharevich-Khalatnikov (HVBK) two-fluid model for a superfluid. In the second part of our study, we elucidate the statistical properties of two-dimensional, homogeneous, isotropic superfluid turbulence in the simplified HVBK model, with values for the mutual-friction coefficients that are comparable to those we obtain from the first part of our study

The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals

Conrad Thesis: A Study of Discrepancies Between Advanced Placement (AP) Calculus AB and BC Exam Scores
No full textAP Calculus AB and AP Calculus BC are nearly identical courses. However, AP Calculus AB exam scores are among the lowest exam scores annually while AP Calculus BC exam scores are typically among the highest scores each year. Further, the AP Calculus BC exam AB subscores are also higher, on average, than the AP Calculus AB scores overall.
This thesis explores the discrepancies between AP Calculus AB and AP Calculus BC exam scores. The researcher felt the difference in scores likely had to do with the intrinsic motivation an individual student had when enrolling in the course and how that student fared throughout the school year. This thesis examined four school years’ worth of enrollment data at one online provider and compared this data to AP exam scores. Further, a survey was given to students both in local districts as well as this same online provider in the 2017-2018 school year, asking individual students to report their reason(s) for enrolling in their Calculus course, their semester scores, and their AP exam score.
The data from the 2017-2018 school year did not show statistically significant data to correlate enrollment reason(s) to AP exam scores. The survey questions, however, could be broken down even further than the researcher did for this project. In future studies, this same survey could be analyzed more granularly or given with restrictions to students who partake in the survey to glean more accurate or detailed data.Mathematics for Teachin
Air-stable Four-Coordinate Cobalt(II) Single-Ion Magnets
No full textFor single ion magnets (SIMs), understanding the effects of the local coordination environment and ligand field on magnetic anisotropy is key to controlling their magnetic properties. Here we present a series of tetracoordinate cobalt(II) complexes of the general formula [FL2Co]X2 (where FL is a bidentate diamido ligand) whose electron-withdrawing -C6F5 substituents confer stability under ambient conditions. Depending on the cations X, these complexes adopt structures with greatly varying dihedral twist angle between the N-Co-N' chelate planes in the solid state (48.0 to 89.2°). AC and DC field magnetic susceptibility measurements show this to translate into very different magnetic properties, the axial zero-field splitting (ZFS) parameter D ranging from -69 cm-1 to -143 cm-1 with substantial or negligible rhombic component E, respectively. A close to the orthogonal arrangement of the two {N,N'}-chelating - and -donor ligands at the Co(II) ion is found to raise the energy barrier for magnetic relaxation to above 400 K. Multireference ab-initio methods were employed to describe the complexes’ electronic structures, and the results were analyzed within the framework of ab-initio ligand field theory to probe the nature of the metal-ligand bonding and spin-orbit coupling. A relationship between the energy gaps of the first few electronic transitions and the ZFS was established, and the ZFS was correlated with the dihedral angle as well as with the metal-ligand bonding variations, viz. the two angular overlap parameters and . These findings not only give rise to a Co(II) SIM showing open hysteresis up to 3.5 K at a sweep rate of 30 Oe/s, but they also provide design guidelines for Co(II) complexes with favorable SIM signatures or even switchable magnetic relaxation properties
Ab initio pair potentials at metal-ceramic interfaces
No full textA systematic approach is proposed to obtain the interfacial interatomic potentials. By inverting ab initio adhesive energy curves for the metal-MgO ceramic interfaces, We derive interfacial potentials between Ag and O2-, Ag and Mg2+, Al and O2-, Al and Mg2+. The interfacial potentials, obtained from this method, demonstrate general features of bondings between metal atoms and ceramic ions
Perceptions of pre- and post-event impacts of PEI 2014 year-long celebrations
No full textThis study examines Canadian perceptions of pre- and post-event impacts of the PEI 2014 Celebrations using the 2013 and 2015 surveys of PEI residents and other Canadians conducted by the Centre for Tourism Research. Overall, results indicate that Canadians’ awareness of, knowledge about, and attitudes toward the 1864 Charlottetown Conference and the PEI 2014 Celebrations increased and positively changed over time. The research also suggests that event organizers and/or destination tourism managers need to put greater emphasis on the “socio-cultural aspects” of the event such as community participation and cultural identity, and make an effort to increase tourism volume and value in order to obtain strong support from residents and be successful
Remarkable Description of a New Species of Apocryptus, 1932
No full textThe genus Apocryptus was established by Uchida in 1932 for the species Apocryptus issikii. The genus is distinguished by truncate apical margin with a pair of tubercles at the middle. The genus is known by two species viz., Apocryptus tikari Gupta & Gupta, 1983 and Apocryptus flavofacies Gupta & Gupta, 1983 from India. A new species of Apocryptus, Apocryptus indicus is described from India as a key for identification
