description: A new high-efficiency and low-background system for the measurement of natural gamma radioactivity in marine sediment and rock cores retrieved from beneath the seabed was designed, built, and installed on the JOIDES Resolution research vessel. The system includes eight large NaI(Tl) detectors that measure adjacent intervals of the core simultaneously, maximizing counting times and minimizing statistical error for the limited measurement times available during drilling expeditions. Effect to background ratio is maximized with passive lead shielding, including both ordinary and low-activity lead. Large-area plastic scintillator active shielding filters background associated with the high-energy part of cosmic radiation. The new system has at least an order of magnitude higher statistical reliability and significantly enhances data quality compared to other offshore natural gamma radiation (NGR) systems designed to measure geological core samples. Reliable correlations and interpretations of cored intervals are possible at rates of a few counts per second.

description: In this paper we study the action of the Binomial and Invert (interpolated) operators on the set of linear recurrent sequences. We prove that these operators preserve this set, and we determine how they change the characteristic polynomials. We show that these operators, with the aid of two other elementary operators (essentially the left and right shifts), can transform any impulse sequence (a linear recurrent sequence starting from $(0,...,0,1)$) into any other impulse sequence, by two processes that we call \emph{construction} and \emph{deconstruction}. Finally, we give some applications to polynomial sequences and pyramidal numbers. We also find a new identity on Fibonacci numbers, and we prove that $r$--bonacci numbers are a Bell polynomial transform of the $(r-1)$--bonacci numbers.

description: We calculate profiles of spectral lines from an extended outflow from the compact object (a black hole or a neutron star). We assume that the bulk velocity of the flow increases during a short phase of acceleration and then rapidly decreases forming a failed wind. We also study the wind which is only decelerating. We show that depending on the relative strength of the gravitational redshifting line profiles from such winds may be of several types: distorted P-Cygni (emission and blueshifted absorption); W-shaped (absorption-emission-absorption) and inverted P-Cygni (emission-redshifted absorption). The latter case is expected from accretion flows where the velocity is directed inwards; however, we show that inverted P-Cygni profile can be produced by the failed wind, provided the line is formed within several tens of Schwarzschild radii from the compact object.

description: Embedded, but rarely made explicit within liberal environmental rhetoric, is a focus on the individual as the primacy locus of change. Proponents of this atomized conception of responsibility suggest widespread environmental degradation— the product of individual overconsumption and poor decision making— can be addressed through individual lifestyle changes. According to this logic, individuals can ‘do their bit’ for the environment by buying ‘green,’ recycling, consuming less, and ‘living lightly.’ Despite the ostensible neutrality, the individualization of responsibility is in fact a deeply gendered notion. The injunction to make eco-friendly lifestyle changes results in an intensification of household labour and responsibility women undertake disproportionately. While there is a body of environmental sociological literature that recognizes this gendered division of eco-labour, there have been few efforts to critically theorize this gender gap. Contributing to these theoretical efforts, I argue that a gender-blind environmental approach based on ‘the individual’ as a homogenous, apolitical theoretical concept, depoliticizes environmental degradation as a space of political contestation. Without acknowledging the variation amongst individuals, the individualization of responsibility obfuscates the power asymmetry built into structures of the status quo, thereby stifling critique and the possibility of necessary structural change.

Symmetry-enhanced supertransfer of delocalized quantum states

Year: 2010

description: Coherent hopping of excitation rely on quantum coherence over physically extended states. In this work, we consider simple models to examine the effect of symmetries of delocalized multi-excitation states on the dynamical timescales, including hopping rates, radiative decay, and environmental interactions. While the decoherence (pure dephasing) rate of an extended state over N sites is comparable to that of a non-extended state, superradiance leads to a factor of N enhancement in decay and absorption rates. In addition to superradiance, we illustrate how the multi-excitonic states exhibit `supertransfer' in the far-field regime: hopping from a symmetrized state over N sites to a symmetrized state over M sites at a rate proportional to MN. We argue that such symmetries could play an operational role in physical systems based on the competition between symmetry-enhanced interactions and localized inhomogeneities and environmental interactions that destroy symmetry. As an example, we propose that supertransfer and coherent hopping play a role in recent observations of anomolously long diffusion lengths in nano-engineered assembly of light-harvesting complexes.

description: Excerpts from the report: Soybeans are the most important agricultural export cash crop in the United States. Their use is widespread in animal feeds, human foods, and industrial applications. As the world population continues to grow and animal protein becomes increasingly scarce, soybeans will likely play a vital role in supplying a larger share of the protein needs of the world. Losses in quality of soybeans are largely the result of modern harvesting, transport, storage, and handling methods. It is estimated that soybeans are augured, dumped, and otherwise handled from 15 to 20 times between the farm and delivery to the final foreign customer. This often results in quality deterioration and breakage that seriously concerns both the overseas and the domestic buyers. The research reported here is part of a broader project to find ways of reducing transport, handling, and storage costs and quality losses for shipments of U.S. soybeans to both foreign and domestic markets. Its objectives are to identify and measure the types and extent of physical damage and quality losses, and to assess the feasibility in introducing alternative methods. These objectives are being implemented by documenting quality differences between origin and destination, studying ways for reducing physical and quality losses during handling and transport, and developing alternative handling and transport methods in order to minimize these losses.
STEM outreach facilitation as a catalyst for 21st century teacher education

Year: 2018

description: This study provides an in-depth description of teacher candidates (TCs)’ experiences of their participation in a family-oriented science, technology, engineering, and mathematics (STEM) outreach event organized at a Canadian university. In the event, TCs facilitated mentally-engaging hands-on activities to the public as part of a General Science Secondary Methods course. The aim of the study is to further knowledge of the possible role of STEM outreach in teacher education programs, and to learn how this outreach experience impacts TCs’: a) pedagogical content knowledge (PCK); b) communication skills; c) motivation to teach STEM; and d) understanding of how STEM can be taught and learned effectively. This study is situated within a social-constructivist theoretical framework and employed an intrinsic case study methodology with a Partially Mixed Concurrent Dominant Status Design. Although the quantitative facet of the study was given less weight, it informed the analysis of the qualitative data. The data from the pre-event survey (n=29) revealed TCs’ passion for STEM as their greatest self-reported strength, whereas their lack of PCK was self-reported as their greatest limitation. Moreover, the participants predicted that activity facilitation at the event would enhance their teaching skills by allowing them to put their content knowledge into practice to facilitate visitors’ learning experiences. Furthermore, the findings from post-event focus group discussions (n=46) and individual interviews (n=9) indicated that this outreach experience enabled TCs to: a) expand pedagogical content knowledge; b) increase awareness of the role of effective communication on STEM teaching and learning; c) increase or reinforce appreciation of STEM hands-on activities for cognitive and affective reasons; d) enhance or strengthen understanding of the importance of parental engagement with children’s STEM education; and e) put in practice some of the theories learned in the teacher education program. Evidence of the above emerged through TCs’ engagement in the event preparation, activity facilitation at the event, and post-event reflections.

description: The behavior of antiferromagnetic domain wall (ADW) against the background of a periodic ferroelectric domain structure has been investigated. It has been shown that the structure and the energy of ADW change due to the interaction with a ferroelectric domain structure. The ferroelectric domain boundaries play the role of pins for magnetic spins, the spin density changes in the vicinity of ferroelectric walls. The ADW energy becomes a periodical function on a coordinate which is the position of ADW relative to the ferroelectric domain structure. It has been shown that the energy of the magnetic domain wall attains minimum values when the center of the ADW coincides with the ferroelectric wall and the periodic ferroelectric structure creates periodic coercitivity for the ADW. The neighbouring equilibrium states of the ADW are separated by a finite potential barrier.

Observation and studies of jet quenching in PbPb collisions at nucleon-nucleon center-of-mass energy = 2.76 TeV

description: Jet production in PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV was studied with the CMS detector at the LHC, using a data sample corresponding to an integrated luminosity of 6.7 inverse microbarns. Jets are reconstructed using the energy deposited in the CMS calorimeters and studied as a function of collision centrality. With increasing collision centrality, a striking imbalance in dijet transverse momentum is observed, consistent with jet quenching. The observed effect extends from the lower cut-off used in this study (jet transverse momentum = 120 GeV/c) up to the statistical limit of the available data sample (jet transverse momentum approximately 210 GeV/c). Correlations of charged particle tracks with jets indicate that the momentum imbalance is accompanied by a softening of the fragmentation pattern of the second most energetic, away-side jet. The dijet momentum balance is recovered when integrating low transverse momentum particles distributed over a wide angular range relative to the direction of the away-side jet.

description: Understanding under what conditions interacting populations, whether they be plants, animals, or viral particles, coexist is a question of theoretical and practical importance in population biology. Both biotic interactions and environmental fluctuations are key factors that can facilitate or disrupt coexistence. To better understand this interplay between these deterministic and stochastic forces, we develop a mathematical theory extending the nonlinear theory of permanence for deterministic systems to stochastic difference and differential equations. Our condition for coexistence requires that there is a fixed set of weights associated with the interacting populations and this weighted combination of populations' invasion rates is positive for any (ergodic) stationary distribution associated with a subcollection of populations. Here, an invasion rate corresponds to an average per-capita growth rate along a stationary distribution. When this condition holds and there is sufficient noise in the system, we show that the populations approach a unique positive stationary distribution. Moreover, we show that our coexistence criterion is robust to small perturbations of the model functions. Using this theory, we illustrate that (i) environmental noise enhances or inhibits coexistence in communities with rock-paper-scissor dynamics depending on correlations between interspecific demographic rates, (ii) stochastic variation in mortality rates has no effect on the coexistence criteria for discrete-time Lotka-Volterra communities, and (iii) random forcing can promote genetic diversity in the presence of exploitative interactions.

description: The properties of the relativistic alpha fragments produced in interactions of 84^Kr at around 1 A GeV in nuclear emulsion are investigated. The experimental results are compared with the similar results obtained from various projectiles with emulsion interactions at different energies. The total, partial nuclear cross-sections and production rates of alpha fragmentation channels in relativistic nucleus-nucleus collisions and their dependence on the mass number and initial energy of the incident projectile nucleus are investigated. The yields of multiple alpha fragments emitted from the interactions of projectile nuclei with the nuclei of light, medium and heavy target groups of emulsion-detector are discussed and they indicate that the projectile-breakup mechanism seems to be free from the target mass number. It is found that the multiplicity distributions of alpha fragments are well described by the Koba-Nielsen-Olesen (KNO) scaling presentation. The mean multiplicities of the freshly produced newly created charged secondary particles, normally known as shower and secondary particles associated with target in the events where the emission of alpha fragments were accompanied by heavy projectile fragments having Z value larger than 4 seem to be constant as the alpha fragments multiplicity increases, and exhibit a behavior independent of the alpha fragments multiplicity.

description: We investigate the fermionic condensate and the vacuum expectation value of the energy-momentum tensor for a massive fermionic field in the geometry of two parallel plate on the background of Minkowski spacetime with an arbitrary number of toroidally compactified spatial dimensions, in the presence of a constant gauge field. Bag boundary conditions are imposed on the plates and periodicity conditions with arbitrary phases are considered along the compact dimensions. The boundary induced parts in the fermionic condensate and the vacuum energy density are negative, with independence of the phases in the periodicity conditions and of the value of the gauge potential. Interaction forces between the plates are thus always attractive. However, in physical situations where the quantum field is confined to the region between the plates, the pure topological part contributes as well, and then the resulting force can be either attractive or repulsive, depending on the specific phases encoded in the periodicity conditions along the compact dimensions, and on the gauge potential, too. Applications of the general formulas to cylindrical carbon nanotubes are considered, within the framework of a Dirac-like theory for the electronic states in graphene. In the absence of a magnetic flux, the energy density for semiconducting nanotubes is always negative. For metallic nanotubes the energy density is positive for long tubes and negative for short ones. The resulting Casimir forces acting on the edges of the nanotube are attractive for short tubes with independence of the tube chirality. The sign of the force for long nanotubes can be controlled by tuning the magnetic flux. This opens the way to the design of efficient actuators driven by the Casimir force at the nanoscale.

description: We point out that there is a nonabelian instability for a nonabelian plasma which does not allow both for a net nonzero color charge and the existence of field configurations which are coherent over a volume $v$ whose size is determined by the chemical potential. The basic process which leads to this result is the Schwinger decay of chromoelectric fields, for the case where the field arises from commutators of constant potentials, rather than as the curl of spacetime dependent potentials. In terms of the fields, instability is obtained when Tr(DF)^2 > 0.

Advancing citizen participationh governance and the right to health in brazil : the role of the national health council in healt
Creators: name: Garcia, Regiane Alves
Publisher: name: University of British Columbia
Year: 2018

description: Brazil has established a constitutional right to health for its citizens. The attention of commentators and the legal community has been focused on the role of the courts in defining the state’s obligation to provide access to certain forms of healthcare services. This dissertation focuses on a rather neglected aspect of Brazil’s right to health: citizen participation in health governance. In this dissertation I argue that Brazil’s right to health includes a state duty to establish a health system that incorporates citizen participation. The objectives of this dissertation are to analyze the constitutional requirements for citizen’s participation and to examine whether the National Health Council (“NHC”), the participation body at the national level of health governance -- meets these constitutional requirements. In pursuing these objectives, I analyzed Brazil’s constitutional and legislative framework for citizen participation, conducted qualitative interviews with a selection of Council’s members, and carried out naturalistic observations of Council’s meetings. The dissertation uncovers questions and concerns about the National Health Council’s compliance with constitutional requirements. The analysis identifies two key issues: Council members lack clarity with respect to the scope of the Council’s legal role, and the Council has not been given full legal authority to carry out its constitutional mandate. The legal analysis provides an understanding of the body of law governing participation in the NHC and its relation to the right to health requirements. The qualitative research yields important information about the practice of participation in the NHC, including the perspectives, understandings and critiques of NHC members. Together, the legal and qualitative research produce a deeper understanding of the constitutional mandate for citizen participation, as well as specific recommendations designed to ensure that participation in the National Council achieves the benefits sought through Brazil’s ambitious constitutional mandate. In addition, Brazil’s constitutional experience with participation in health may provide useful guidance to other countries considering evidence-based policies to foster responsive and accountable health governance through citizen participation.

description: In this paper we study optimal control problems for nonholonomic systems defined on Lie algebroids by using quasi-velocities. We consider both kinematic, i.e. systems whose cost functional depends only on position and velocities, and dynamic optimal control problems, i.e. systems whose cost functional depends also on accelerations. The formulation of the problem directly at the level of Lie algebroids turns out to be the correct framework to explain in detail similar results appeared recently (Maruskin and Bloch, 2007). We also provide several examples to illustrate our construction.

Derivation of the Planck Spectrum for Relativistic Classical Scalar Radiation from Thermal Equilibrium in an Accelerating Frame
Creators: name: Boyer, Timothy H.
Publisher: name: arXiv
Year: 2010
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: The Planck spectrum of thermal scalar radiation is derived suggestively within classical physics by the use of an accelerating coordinate frame. The derivation has an analogue in Boltzmann's derivation of the Maxwell velocity distribution for thermal particle velocities by considering the thermal equilibrium of noninteracting particles in a uniform gravitational field. For the case of radiation, the gravitational field is provided by the acceleration of a Rindler frame through Minkowski spacetime. Classical zero-point radiation and relativistic physics enter in an essential way in the derivation which is based upon the behavior of free radiation fields and the assumption that the field correlation functions contain but a single correlation time in thermal equilibrium. The work has connections with the thermal effects of acceleration found in relativistic quantum field theory.

 Notes. This species was described by Wrigley de Basanta et al. (2018) from cold, arid areas of Argentina and Peru, including these collections in the description. The species has only been recorded from the moist chamber culture of the debris of cushion plants of the genus Azorella Lam. The small sporocarps with eggshell-like packed lime crystals develop inside the compact rosettes of the host plant, and they may be present in other areas following the distribution of the genus Azorella. A phylogenetic analysis showed specimens of this species were grouped in a well-supported clade (100/1), distinguishing them from the other species included in the analysis (Wrigley de Basanta et al. 2018).

The targum (1963:Apr. 2 - 1963:Apr. 30)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1963

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 the scaling behavior of the chiral phase transition in QCD in finite and infinite volume

description: We study the scaling behavior of the two-flavor chiral phase transition using an effective quark-meson model. We investigate the transition between infinite-volume and finite-volume scaling behavior when the system is placed in a finite box. We can estimate effects that the finite volume and the explicit symmetry breaking by the current quark masses have on the scaling behavior which is observed in full QCD lattice simulations. The model allows us to explore large quark masses as well as the chiral limit in a wide range of volumes, and extract information about the scaling regimes.In particular, we find large scaling deviations for physical pion masses and significant finite volume effects for pion masses that are used in current lattice simulations.

description: This is a study on jump conditions across the interface between two adjacent phases. The interface behaves as a free boundary, and in sharp interface models jump conditions are used to determine the values of thermodynamic fields at the free boundaries. In this study the jump conditions are derived from balance equations for singular surfaces that do not have singular lines, i.e. triple junctions are not considered here. At first we present the most general form of jump conditions to give a general framework, from where we consider various special cases with a focus on the influence of mechanical fields on the interfacial processes. The special cases include the Hoffmann/Cahn capillarity vector theory and jump conditions for interfaces where order/disorder transitions are involved. Furthermore we discuss interfacial chemical reaction laws, and in particular the creation and annihilation of vacancies at a liquid/solid interface.

description: The magnetic behavior of $Fe_{3-x}O_4$ nanoparticles synthesized either by high-temperature decomposition of an organic iron precursor or low-temperature co-precipitation in aqueous conditions, is compared. Transmission electron microscopy, X-ray absorption spectroscopy, X-ray magnetic circular dichroism and magnetization measurements show that nanoparticles synthesized by thermal decomposition display high crystal quality and bulk-like magnetic and electronic properties, while nanoparticles synthesized by co-precipitation show much poorer crystallinity and particle-like phenomenology, including reduced magnetization, high closure fields and shifted hysteresis loops. The key role of the crystal quality is thus suggested since particle-like behavior for particles larger than about 5 nm is only observed when they are structurally defective. These conclusions are supported by Monte Carlo simulations. It is also shown that thermal decomposition is capable of producing nanoparticles that, after further stabilization in physiological conditions, are suitable for biomedical applications such as magnetic resonance imaging or bio-distribution studies.

Lost : from a child's perspective
Creators: name: Koenig, Riley
Publisher: name: University of British Columbia
Year: 2018

description: Lost: From a Child’s Perspective is a musical composition for symphony orchestra. It is approximately 16.5 minutes in duration. The piece presents a musical representation of the emotions a child experiences when getting lost. The musical style of the composition draws from 19th and 20th century concert music and film music influences. The first chapter discusses aspects of the composer’s personal life and the influence his upbringing had on the conceptual design of the piece. A brief discussion of programmatic music, and various harmonic and melodic sources that are influences for the piece follows in the second chapter. The third chapter discusses the musical form and style of the composition: medium, formal structure, narrative agents, melodic transformations, harmonic languages, and rhythmic treatment. The final chapter closes with a brief aesthetic statement. A program note and a complete musical score of the composition are included as appendices.

subject: Other language, communication and culture not elsewhere classified

description: One benefit of the lockdown is that there are no in-person events I have to attend, so sleeping in is much more of a viable option, being able to sleep in until 2pm barring any deadlines I have to complete. One downside to the lockdown (especially since it's summer) is that time has become a near meaningless concept for me, and I end up staying up till 4 or 5 am. Besides sleeping I do still have to do work assigned by the school seeing as they decided to continue as a virtual term. Outside of that however, the day is lost in a haze of TV, games, reading, cooking, eating and exercising.
High-field magnetization and magnetic phase transition in CeOs2Al10

description: We have studied the magnetization of CeOs2Al10 in high magnetic fields up to 55 T for H // a and constructed the magnetic phase diagram for H // a. The magnetization curve shows a concave H dependence below T_max \sim40 K which is higher than the transition temperature T_0 \sim29 K. The magnetic susceptibility along the a-axis shows a smooth and continuous decrease down to \sim20 K below T_max \sim40 K without showing an anomaly at T_0. From these two results, a Kondo singlet is formed below T_max and coexists with the antiferro magnetic order below T_0. We also propose that the larger suppression of the spin degrees of freedom along the a-axis than along the c-axis below T_max is associated with the origin of the antiferro magnetic component.
