description: A recent experiment on the multiferroic BiMn$_2$O$_5$ compound under a strong applied magnetic field revealed a rich phase diagram driven by the coupling of magnetic and charge (dipolar) degrees of freedom. Based on the exchange-striction mechanism, we propose here a theoretical model with the intent to capture the interplay of the spin and dipolar moments in the presence of a magnetic field in BiMn$_2$O$_5$. Experimentally observed behavior of the dielectric constants, magnetic susceptibility, and the polarization is, for the most part, reproduced by our model. The critical behavior observed near the polarization reversal $(P=0)$ point in the phase diagram is interpreted as arising from the proximity to the critical end point.

description: In dieser Studie werden die Alterungseigenschaften von Lithium-Ionen-Batterien unter konventionellen Zyklustests und realistischen Fahrprofilprüfungen untersucht. Wir verwenden regelmäßige Kapazitätstests und elektrochemische Impedanzspektroskopie für eine umfassende Analyse des Gesundheitszustandes. Für diese Untersuchung haben wir handelsübliche, runde LFP-Zellen im Format 21700 verwendet. Die Ergebnisse zeigen einen stärkeren Kapazitätsverlust bei realistischen Fahrprofilen im Vergleich zu konventionellen Zyklen. Diese Diskrepanz deutet darauf hin, dass die Rekuperationsphasen ein Schlüsselfaktor für die beschleunigte Alterung von Lithium-Ionen-Batterien sind, die in Elektrofahrzeugen eingesetzt werden. Diese Forschung unterstreicht die Bedeutung realistischer Belastungsszenarien für die Bewertung der Batterielebensdauer und kann zur Entwicklung fortschrittlicherer Batteriemanagementsysteme in Elektrofahrzeugen beitragen.

description: Via a direct coupling between the magnetic order parameter and the singlet Josephson supercurrent, we detect spin-wave resonances, and their dispersion, in ferromagnetic Josephson junctions in which the usual insulating or metallic barrier is replaced with a weak ferromagnet. The coupling arises within the Fraunhofer interferential description of the Josephson effect, because the magnetic layer acts as a time dependent phase plate. A spin-wave resonance at a frequency ws implies a dissipation that is reflected as a depression in the current-voltage curve of the Josephson junction when hbar ws = 2eV. We have thereby performed a resonance experiment on only 10^7 Ni atoms.

description: Sunspots are concentrations of magnetic field on the visible solar surface that strongly affect the convective energy transport in their interior and surroundings. The filamentary outer regions (penumbrae) of sunspots show systematic radial outward flows along channels of nearly horizontal magnetic field. These flows were discovered 100 years ago and are present in all fully developed sunspots. Using a comprehensive numerical simulation of a sunspot pair, we show that penumbral structures with such outflows form when the average magnetic field inclination to the vertical exceeds about 45 degrees. The systematic outflows are a component of the convective flows that provide the upward energy transport and result from anisotropy introduced by the presence of the inclined magnetic field.

description: The magnetic properties of the diluted magnetic semiconductor Ga_{1-x}Mn_{x}As are studied within the dynamical cluster approximation. We use the k-dot-p Hamiltonian to describe the electronic structure of GaAs with spin-orbit coupling and strain effects. We show that nonlocal effects are essential for explaining the experimentally observed transition temperature and saturation magnetization. We also demonstrate that the cluster anisotropy is very strong and induces rotational frustration and a cube-edge direction magnetic anisotropy at low temperature. With this, we explain the temperature-driven spin reorientation in this system.

description: The interpretation of Y(4140) as a $D^{*}_s\bar{D}^{*}_s$ molecule is studied dynamically in the one boson exchange approach, where $σ$, $η$ and $ϕ$ exchange are included. Ten allowed $D^{*}_s\bar{D}^{*}_s$ states with low spin parity are considered, we find that the $J^{PC}=0^{++}$, $1^{+-}$, $0^{-+}$, $2^{++}$ and $1^{--}$ $D^{*}_s\bar{D}^{*}_s$ configurations are most tightly bound. We suggest the most favorable quantum numbers are $J^{PC}=0^{++}$ for Y(4140) as a $D^{*}_s\bar{D}^{*}_s$ molecule, however, $J^{PC}=0^{-+}$ and $2^{++}$ can not be excluded. We propose to search for the $1^{+-}$ and $1^{--}$ partners in the $J/ψη$ and $J/ψη'$ final states, which is an important test of the molecular hypothesis of Y(4140) and the reasonability of our model. The $0^{++}$ $B^{*}_s\bar{B}^{*}_s$ molecule is deeply bound, experimental search in the $Υ(1S)ϕ$ channel at Tevatron and LHC is suggested.

description: Let M be an archimedean quadratic module of real t-by-t matrix polynomials in n variables, and let S be the set of all real n-tuples where each element of M is positive semidefinite. Our key finding is a natural bijection between the set of pure states of M and the cartesian product of S with the real projective (t-1)-space. This leads us to conceptual proofs of positivity certificates for matrix polynomials, including the recent seminal result of Hol and Scherer: If a symmetric matrix polynomial is positive definite on S, then it belongs to M. We also discuss what happens for non-symmetric matrix polynomials or in the absence of the archimedean assumption, and review some of the related classical results. The methods employed are both algebraic and functional analytic.

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

Alternative uses for waste newspaper : an investigation into the economic viability of options for reprocessing newspaper in Tasmania in 1991
Creators: name: Bakker, MB
Publisher: name: University Of Tasmania
Year: 2023

description: The importance of, and impediments to, effective management of newspaper waste in Australia are addressed. It is appreciated that it is vital to establish facilities to recycle and reprocess newspaper as an avenue for appreciating the value of newspaper. The existence of collection industries depends on the creation of markets for the reprocessed material. Options for reprocessing waste newspaper are identified, and include the manufacture of pulp moulded products, building materials, animal bedding, animal fodder and file folders. Newspaper can also be used as a dewatering agent and as an industrial and domestic fuel source. The viability of establishing reprocessing facilities in Tasmania is considered on environmental, technical and economic grounds. On purely economic terms, it was found that the use of newspaper as a source of industrial fuel and in the production of non-adhesive bonded panel board are the most attractive means of generating a demand for waste newspaper. Avenues for governmental, community and industrial intervention to encourage further use of waste newspaper are examined.

description: Let B be a sigma-unital C*-algebra. We show that every strongly continuous E_0-semigroup on the algebra of adjointable operators on a full Hilbert B-module E gives rise to a full continuous product system of correspondences over B. We show that every full continuous product system of correspondences over B arises in that way. If the product system is countably generated, then E can be chosen countable generated, and if E is countably generated, then so is the product system. We show that under these countability hypotheses there is a one-to-one correspondence between E_0-semigroup up to stable cocycle conjugacy and continuous product systems up isomorphism. This generalizes the results for unital B to the sigma-unital case.

Possible Dark States induced by a Surface Wave along a Vacuum-Matter Boundary

description: Possible dark states could be induced after derivations of the entrainment of matter induced by a surface wave propagating along the flexible vacuum-matter boundary by considering the nonlinear coupling between the interface and the rarefaction effect. The nonrelativistic limit of the relativistic Navier-Stokes equations was considered and analytically solved by a perturbation approach. The critical reflux values associated with the product of the second-order body forcing and the Reynolds number (representing the viscous dissipations) decrease as the Knudsen number (representing the rarefaction measure) increases from zero to 0.1. We obtained the critical bounds for possible dark states corresponding to specific Reynolds numbers (ratio of wave inertia and viscous dissipation effects) and wave numbers which might be linked to the dissipative evolution of certain large-scale structure during the relativistic heavy-ion collisions.

Deinking of newsprint by flotation method
Creators: name: Ariadi, Bimo
Publisher: name: University Of Tasmania
Year: 2023

description: There is much current interest in development of processes which lead to . greater utilisation of secondary fibres in papermalcing operations, both in Australia and overseas. The removal of ink from paper (deinking) is a major step in these processes. After repulping, ink can be removed from aqueous suspension by a number of techniques, one of which is flotation. Most commercial deinking facilities use flotation as the principle method of ink removal. Studies have been made on the effects of flotation conditions, feedstock composition, and surfactant during flotation deinking of newspaper (ONP) and magazines (OMG). Type of surfactant and amount of surfactant appear to affect deinking performance. Temperature, pH, and furnish also appear to affect deinking efficiency of the various surfactants investigated. There is an optimum pH of 8.5 for flotation deinking of a 70/30 mixture of ONP/OMG using a fatty acid type deinking surfactant. Increasing proportions of magazines (ash content of 26%) in the feedstock results in a deinked pulp with higher brightness. However, it was found that the higher brightness attained is largely due to the addition of higher brightness materials from the magazines, rather than a more efficient mechanism of ink removal from the ONP. Addition of Ca2+ in the pulping stage at low level of addition seem to improve the brightness response for deinking of newspaper with fatty acids. High level of addition of Ca2+ seems to have detrimental effect. An attempt is made to explain the results in terms of a model describing the flotation deinking process and the interactions occurring between surfactant molecules, ink particles, fibres, and air bubbles.

description: Cyber-physical systems (CPS) and IoT systems are nowadays commonly designed as self-adaptive, endowing them with the ability to dynamically reconfigure to reflect their changing environment. This adaptation concerns also the security, as one of the most important properties of these systems. Though the state of the art on adaptivity in terms of security related to these systems can often deal well with fully anticipated situations in the environment, it becomes a challenge to deal with situations that are not or only partially anticipated. This uncertainty is however omnipresent in these systems due to humans in the loop, open-endedness and only partial understanding of the processes happening in the environment. 
In this paper, we partially address this challenge by featuring an approach for tackling access control in face of partially unanticipated situations. We base our solution on special kind of aspects that build on existing access control system and create a second level of adaptation that addresses the partially unanticipated situations by modifying access control rules.
The approach is based on our previous work where we have analyzed and classified uncertainty in security and trust in such systems and have outlined the idea of access-control related situational patterns. The aspects that we present in this paper serve as means for application-specific specialization of the situational patterns. We showcase our approach on a simplified but real-life example in the domain of Industry 4.0 that comes from one of our industrial projects.
Planning evaluation of the facilities for the treatment of solid wastes at the Premier Street landfill in the District of North Vancouver
Creators: name: Saunders, Frederick Michael
Publisher: name: University of British Columbia
Year: 2011

description: Each year the problem of where to dispose and how to dispose of commercial, domestic and industrial solid wastes becomes worse. The growth rate of solid wastes continues to expand both because of the per capita increase in solid waste produced and because of population growth. Traditional disposal techniques such as dumps and landfills are becoming more expensive to operate mainly because of the lack of suitable land and the increased competition to obtain it. The growing inability of established disposal systems to handle the expanding solid wastes, generates further impetus to find new disposal techniques. Ignored environmental effects, particularly the growing pollution of air, land and water are no longer as acceptable to an increasingly pollution conscious public. With the changes in community attitudes towards the preservation of natural assets, disposal techniques previously too expensive to compete with traditional disposal techniques now are becoming more acceptable. The purpose of this thesis is to examine whether the benefits of using a new grinding disposal technique outweigh costs. The community selected for the analysis was the District of North Vancouver, British Columbia, which forms part of the Greater Vancouver Metropolitan Area. Presently, the District of North Vancouver operates a controlled landfill disposal technique known as the Premier Street Landfill. Various forms of air, land and water pollution occur at or from the site. The present landfill disposal technique is economically efficient with disposal costs of about $1.00 per ton of solid waste disposed. A benefit-cost analysis was conducted using the present landfill disposal technique as the control situation and the grinding disposal technique as the possible alternative. The point of view of the analysis was that of the Corporation of the District of North Vancouver which would be the decision making authority. For comparison purposes, different volume capacities were used in the analysis. The district's borrowing rate of 7% was used as the discount rate. Rates above and below the selected discount rate were also used in the analysis for comparison purposes. The value of net intangible benefits was also calculated to show what value would have to be placed on these benefits by the District of North Vancouver to justify the use of the disposal techniques involved in the analysis which were not as economically efficient. The results of the benefit-cost analysis showed that the present controlled landfill technique is economically more efficient than the proposed grinding disposal technique. The District of North Vancouver would consequently not be justified in converting to a grinding disposal technique under present conditions, unless the value of the net intangible benefits was accepted as a legitimate monetary expense.

Air-sea exchange of CO2 over the Antarctic seasonal ice zone
Creators: name: Beggs, Helen Mary
Publisher: name: University Of Tasmania
Year: 2023

description: The Antarctic Seasonal Ice Zone (ASIZ) is potentially a large contemporary sink for anthropogenic CO2 due to the formation of bottom water along the Antarctic coast. However, south of 55¬¨‚àûS, the lack of measurements of the fugacity of CO2 in surface seawater (fCO2), or the concentration and ratio of stable carbon isotopes of atmospheric CO2, has meant that it has been difficult to determine whether the ASIZ acts as a net source or sink for atmospheric CO2. This study contributes to, and is largely based on, new measurement programmes of oceanic fCO 2 and the concentration and 13C/12C ratio of atmospheric CO2 over the region of the Southern Ocean between Australia and the Antarctic continent, with particular emphasis on data from regions of pack ice. Using fCO2 data from six voyages of the RSV Aurora Australis, it was estimated that between 1 October 1992 and 31 March 1993 the ocean south of 55¬¨‚àûS, between 60¬¨‚àûE and 150¬¨‚àûE, sequestered 0.025 ¬¨¬± 0.013 Gt C over an area of ocean equivalent to 19% of the maximum area of open water south of 55¬¨‚àûS. The CO2 sink was most pronounced west of 105¬¨‚àûE (0.026 ¬¨¬± 0.013 Gt C), where it was associated with intense summer phytoplankton blooms following the melting of sea-ice. In conjunction with the sampling of oceanic fCO 2, flasks were regularly filled on the ship with dry air and later analysed for levels of CO2 and its 13C/12C ratio. This provided the opportunity to observe atmospheric variations directly forced by fluctuations in fCO2, temperature, and the 13C112C ratio of dissolved inorganic carbon (DIC) in the surface ocean. Sea surface temperature and 13C/12C-DIC effects are transmitted to the atmosphere by gross air-sea fluxes of CO2 in the absence of net exchange. Over the ice-free region of the Southern Ocean between 44¬¨‚àûS and 60¬¨‚àûS, from 85¬¨‚àûE to 160¬¨‚àûE, atmospheric 13CO2/12CO2 values were dominated by a linear dependence on sea surface temperature (0.0041 ¬¨¬± 0.0003 ¬¨‚àû/00 ¬¨‚àûC-1 ), due to the \equilibrium\" isotopic fractionation of CO2 during air-sea exchange. During late spring and summer over the region of the ASIZ south of 60¬¨‚àûS between 60¬¨‚àûE and 105¬¨‚àûE the effect of sea surface temperature on atmospheric 13CO2/12CO2 values was overwhelmed by the effect of high marine productivity on 13C/12C -DIC. It is demonstrated that the impact of net air-sea flux of 13CO2 on atmospheric ratios of 13CO2/12CO2 can be measured more easily than the impact of net CO2 flux on atmospheric mixing ratios of CO2 . Long-term changes in sea surface temperature and productivity over the ASIZ and therefore net ocean uptake can be more accurately determined from isotopic ratios of 13CO2/12CO2 in baseline air samples from a coastal Antarctic station than from mixing ratios of CO2 in the same samples."

description: The Monte Carlo wave function method or the quantum trajectory/jump approach is a powerful tool to study dissipative dynamics governed by the Markovian master equation, in particular for high-dimensional systems and when it is difficult to simulate directly. In this paper, we extend this method to the non-Markovian case described by the generalized Lindblad master equation. Two examples to illustrate the method are presented and discussed. The results show that the method can correctly reproduce the dissipative dynamics for the system. The difference between this method and the traditional Markovian jump approach and the computational efficiency of this method are also discussed.

description: We present a theoretical calculation of the pull-in control in capacitive micro switches actuated by Casimir forces, using external magnetic fields. The external magnetic fields induces an optical anisotropy due to the excitation of magneto plasmons, that reduces the Casimir force. The calculations are performed in the Voigt configuration, and the results show that as the magnetic field increases the system becomes more stable. The detachment length for a cantilever is also calculated for a cantilever, showing that it increases with increasing magnetic field. At the pull-in separation, the stiffness of the system decreases with increasing magnetic field.

description: Increased connectivity and the digitization of cultural and literary artifacts means that the humanities are facing a deluge of new data and newly accessible information. In response, scholarship in the humanities, traditionally focused on interpretation and reinterpretation, is increasingly expanding its methodological approaches and its definitions of the scope of its evidence. What kind of data are humanists using to conduct their research? What does the growing emphasis on reproducibility in scientific and computational work mean for the humanities? This talk explores the implications of the changing answers to these questions for humanities students and scholars, and discusses ways libraries can support transparency and best practices among humanists new to computational and data-intensive work.

description: A recently developed formulation for a direct treatment of the equations for two- and three-nucleon bound states as set of coupled equations of scalar functions depending only on vector momenta is extended to three-nucleon scattering. Starting from the spin-momentum dependence occurring as scalar products in two- and three-nucleon forces together with other scalar functions, we present the Faddeev multiple scattering series in which order by order the spin-degrees can be treated analytically leading to 3D integrations over scalar functions depending on momentum vectors only. Such formulation is especially important in view of awaiting extension of 3N Faddeev calculations to projectile energies above the pion production threshold and applications of chiral perturbation theory 3N forces, which are to be most efficiently treated directly in such three-dimensional formulation without having to expand these forces into a partial wave basis.

description: The Aharonov-Bohm (AB) effect in a small array of antidots with large aspect ratio is investigated in the quantum Hall regime. The evolution with temperature of the AB oscillations in the magnetic field vs gate voltage (B-Vg) plane reveals the temperature dependence of the screening. The self-consistently screened potential of the compressible band surrounding an antidot is observed to gain progressively steeper slope with increasing temperature.

description: Matchmaking is an age-old practice in the Indian context. What started out as a tradition of seeking partners in close-knit communities, has today expanded to newspapers and online websites. These advertisements however continue to be extremely explicit, content-heavy, and rich sources of cultural and socio-economic individual preferences. In this study, I attempt to use this text, along with computational methods, to understand the most important preferences of individuals seeking partners through newspaper advertisements, and how their preferences vary with time. Moreover, I attempt to qualitatively understand how people employ print versus digital media to facilitate the matchmaking process, and how this impacts the relevance of newspaper matrimonial advertisements. I use robust methods of natural language processing and computational linguistics such as part-of-speech tagging and word embeddings to conduct a longitudinal study across years. I argue that individual preferences of brides and grooms are rooted in gender and cultural biases, and remain constant with time. Using newspaper matrimonial advertisements of a north Indian newspaper, The Tribune, from 2001-2014, I find that there exists a bias for “tall”, “slim”, “fair”, and “beautiful” women, and “handsome”, “tall”, and “intelligent” working men, from the Sikh or Jat community. This underscores the fact that these advertisements are embedded in stereotypical gendered roles and a strong emphasis on intra-faith alliances. The results of this research also highlight the increasing preference of individuals towards using online platforms for matrimonial advertisements. In doing so, this study discovers nuanced biases in the social fabric of Indian matchmaking traditions and raises questions about the relevance of newspaper matrimonial advertisements and their implications on the matchmaking ecosystem.

description: In arXiv:0901.3543, the simplest Yukawa coupling $η\barΨϕχΨ$ was considered for a two-scalar-generated Bloch brane model. Fermionic resonances for both chiralities were obtained, and their appearance is related to branes with internal structure. Inspired on this result, we investigate the localization and resonance spectrum of fermions on a one-scalar-generated $dS$ thick brane with a class of scalar-fermion couplings $η\barΨϕ^kΨ$ with positive odd integer $k$. A set of massive fermionic resonances for both chiralities are obtained when provided large couple constant $η$. We find that the masses and life-times of left and right chiral resonances are almost the same, which demonstrates that it is possible to compose massive Dirac fermions from the left and right chiral resonances. The resonance with lower mass has longer life-time. For a same set of parameters, the number of resonances increases with $k$ and the life-time of the lower level resonance for larger $k$ is much longer than the one for smaller $k$.

title: Micromagentic simulation and Lorentz microscopy of curved ferromagnetic nanowires

description: Ferromagnetic domain walls can be used to encode and propagate information in novel spintronic devices. However, to realize these devices, different materials and geometries that support stable and mobile domain walls need to be investigated. This thesis contributes to the effort by examining domain walls in nanowires with curved profiles using micromagnetic simulations and Lorentz microscopy.

Domain walls in head-to-head cylindrical segment nanowires were explored using micromagnetic simulations. The energy density (a measure of stability) of the resulting domain walls was recorded for each combination of nanowire geometry (half versus quarter cylinder) and nanowire composition (Fe vs. Co). A domain wall with a potential for the field of spintronics due to its narrow extent and strong out-of-plane component was found to stabilise in a wide range of nanowire sizes in both Co and Fe nanowires. Additionally, the effect of the interfacial Dzyaloshinskii-Moriya interaction (iDMI), on the domain wall formation in quarter cylinder nanowires was examined. That resulted in the stabilisation of another promising Néel-like domain wall with a simple one-dimensional rotation of the magnetisation - the 1D wall. Throughout the entire simulation space, the extent of the different domain walls was measured and recorded. Simulated experimental Fresnel mode and differential phase contrast (DPC) images were calculated and used in the quantification of the domain walls comparing magnetisation profiles to those from integrated induction.

Finally, the effect of electrostatic phase on DPC and Fresnel image contrast was examined with respect to domain wall characterisation and classification. Focused electron beam induced deposition (FEBID) was used to deposit physical Co and Fe nanowires of varying width and thickness with a profile similar to the one studied with simulations. The deposition conditions were optimised to produce defined magnetic nanowires with as high saturation magnetisation as possible. Domain walls were successfully nucleated in said nanowires with the application of an external magnetic field and identified using Fresnel mode microscopy. Differential phase contrast (DPC) imaging was then used to obtain accurate maps of the magnetic induction of the nanowires showing a more clear picture of the structure of the different domain walls. Finally, a combination of transmission electron microscopy (TEM), atomic force microscopy (AFM) and DPC imaging was used to obtain a measure of the saturation induction of the FEBID structures and thus infer their elemental purity.
Practice versus graphical representation for maintainance of basic arithmetic competencies : first year primary

description: Educators such as Edith Biggs in Britain and Vincent Glennon and the Cambridge Conference on School Mathematics in the United States have suggested that the amount of time children spend on direct practice of newly learned skills and understandings can be greatly reduced. The Americans propose an Integration of this practice with the presentation and learning of new topics. The British favour an activity approach, where new learnings are put to immediate use, and the need for acquisition and perfection of mathematical competencies becomes obvious to the children. A few American research studies have substantiated the merits of reduced practice, at the intermediate level. This study explores the place of practice for maintenance of the basic competencies of First Year Primary children in British Columbia at the end of the school year. The competencies chosen for study were 1) Numeration: reading, writing and understanding of base ten numerals ≤99, and 2) Computation: addition and subtraction operations with sums and minuend ≤10. The new material, chosen to be presented as an alternative to direct practice, was Graphical Representation, a unit developed from the Nuffield Project booklet, Pictorial Representation 1. Two schools in the Vancouver area were used, the first with a class of 54 children and the second with 34. Parallel pre-tests and post-tests in the basic competencies were administered. During a three week Intervening interval, the Investigator taught the children, who were divided into groups, by random selection, as follows: In the first school, three groups of 18 children were instructed respectively in Graphical Representation, in review and practice, using familiar materials, and in geometry, involving no use of numbers (control group). In the second school, two groups of 17 children were Instructed in Graphical Representation, and in review and practice, respectively. At the end of the experiment, there was no significant difference in the tested numeration competencies of the two experimental groups in their respective schools. The control group showed a slightly lower achievement. Time did not permit a retention test. In the first school, where computational efficiency was low, the results slightly favoured the review and practice group, over the other groups. In the second school, there was no significant difference between the two groups, regarding progress in computational skills. Within Its limitations, this study demonstrates the possibility of maintaining basic competencies, while introducing new topics, at the first year level.

description: Collective flow reflects the dynamical evolution in high-energy heavy ion collisions. In particular, the elliptic flow reflects early collision dynamics.We present a systematic analysis of elliptic flow ($v_{2}$) for identified particles measured in Au + Au and Cu + Cu collisions at $\sqrt{s_{NN}}$ = 200 GeV. Number of quark scaling is tested in the intermediate $p_{T}$ region and in the smaller system (Cu + Cu). The Cu + Cu collisions results are compared with those from ideal hydrodynamic model calculations.

description: Human languages develop over time a set of cultural associations. For example, during the early and mid-twentieth century, the Spanish language in the United States was seen both as a European high literary language and as a language associated with femininity and racial mixture. In my dissertation work, I documented how US modernist poets who translated from Spanish used or resisted those associations as they intervened in controversies over race and style in twentieth century poetics. Coding languages, too, can take on gendered and raced cultural associations. This talk explores the possibility of an analogous set of dynamics in the history of coding languages, exploring their changing cultural associations as languages and how those cultural associations were expressed in changing coding styles or conventions. It draws on the work of Vikram Chandra (Geek Sublime) and other writers exploring the cultural meanings and stylistic associations of computer code.
