Health and wellbeing of international students in an Australian tertiary context
Creators: name: Yue, Y
Publisher: name: University Of Tasmania
Year: 2023

description: The rapid growth of international students in recent years has attracted enormous research interest from different disciplines. Due to the transition to an unfamiliar environment, most international students have experienced various degrees of physical and psychological adjustments. How to help these students maintain a good state of health and improve their psychological wellbeing has become a very important issue worthy to be studied. This study was conducted with a research aim to investigate international tertiary students' health and wellbeing in an Australian regional area. A mix of quantitative and qualitative research method was used to gain deeper insights into the issue. A 60-item questionnaire was utilised to collect quantitative data. A total of 341 international students in the University of Tasmania were recruited to complete the questionnaires. Meanwhile, 20 international students and 5 university staff in the same university were invited to participate in semi-structured interviews to explore their perceptions of the issue in an in-depth manner. Quantitative and qualitative data collected were analysed respectively by Predictive Analytics Software (PASW, version 18) and NVivo (version 8). The findings indicate that academic issues, basic living conditions, financial worries, social contact and racial discrimination are factors significantly influencing international students' physical health as well as their psychological and social wellbeing in the new environment. Demographic variables including age, gender, length of stay in Tasmania and English proficiency are also influential factors. There are eight coping strategies frequently used by the students. Family, friends, university and community are identified as four main sources of support. Lastly, this study also provides some recommendations for enhancing international students' health and wellbeing in their acculturation into a new social and cultural context.
A systematic review of research related to methods of adult education
Creators: name: Stinson, Winona Elizabeth
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this review is to organize the findings of studies on adult education methods according to the Verner conceptual scheme, defining adult education processes according to their inherent characteristics, and to extend or clarify any parts of that scheme. The material reviewed, mainly empirical research conducted with adult subjects, is used to describe the method, the effects of the learning and the characteristics of the participants. The learning goals are classified as information giving, skill developing and knowledge supplying. As the majority of methods had been studied for their uses, little research was available on their maximum learning potential. Prom the description of the methods the key element emerged as the amount of overt participation built into the method, ranging from lowest in methods whose goal is to impart information to greatest in those where learning is conducted on-the-job. The participant studies revealed that the structure of some methods must be modified for more efficient learning. The research showed that the learning goal became more concrete as the amount of overt participation Increases. Therefore a two-dimensional classification scheme has been developed with the amount of overt participation occupying one dimension and the degree of abstraction of the learning goal the other. Areas requiring further research have been indicated.

description: We investigate the storage of light in an atomic sample with a lambda-type coupling scheme driven by optical fields at variable two-photon detuning. In the presence of electromagnetically induced transparency (EIT), light is stored and retrieved from the sample by dynamically varying the group velocity. It is found that for any two-photon detuning of the input light pulse within the EIT transparency window, the carrier frequency of the retrieved light pulse matches the two-photon resonance frequency with the atomic ground state transition and the control field. This effect which is not based on spectral filtering is investigated both theoretically and experimentally. It can be used for high-speed precision measurements of the two-photon resonance as employed e.g. in optical magnetometry.

description: Multimode fibres have recently been employed as high-resolution ultra-thin endoscopes, capable of imaging biological structures deep inside tissue in vivo. Here, we extend this technique to label-free non-linear microscopy with chemical contrast using coherent anti-Stokes Raman scattering (CARS) through a multimode fibre endoscope, which opens up new avenues for instant and in-situ diagnosis of potentially malignant tissue. We use a commercial 125 µm diameter, 0.29 NA GRIN fibre, and wavefront shaping on an SLM is used to create foci that are scanned behind the fibre facet across the sample. The chemical selectivity is demonstrated by imaging 2 µm polystyrene and 2.5 µm PMMA beads with per pixel integration time as low as 1 ms for epi-detection.Multimode fibres have recently been employed as high-resolution ultra-thin endoscopes, capable of imaging biological structures deep inside tissue in vivo.

description: The path-integral measure of a gauge-invariant fermion theory is transformed under the chiral transformation and leads to an elegant derivation of the anomalous chiral Ward-Takahashi identities, as we know from the seminal work of Fujikawa. We present in this work an alternative and illuminating way to calculate the Jacobian in the path-integral measure from the covariant derivative expansion technique used in effective field theory. We present several ways to customize the crucial regularization such that the anomaly is located in the desired current, which is unprecedented within the path integral approach. We are then able to derive, in a transparent and unified way, the covariant, consistent, gravitational, and scale anomalies.
Role of the 39-kDa receptor-associated protein (RAP) in Alzheimer's disease
Creators: name: Hoang, T
Publisher: name: University Of Tasmania
Year: 2023

description: Alzheimer's disease (AD) is the most common form of dementia that gradually worsens over time and leads to death. AD is characterized by an accumulation of ˜í‚â§-amyloid protein (A˜í‚â§) in the brain. Recently, the 39-kDa receptor-associated protein (RAP) has been implicated in the AD pathology. RAP is found mainly in endoplasmic reticulum (ER) and functions as a chaperone for the maturation and trafficking of the low density lipoprotein (LDL) receptor family. Polymorphisms in the RAP gene have been associated with an increased risk of AD. Two studies have shown that down-regulation of RAP expression exacerbates A˜í‚â§ pathology in transgenic mouse models of AD, suggesting that RAP may have an important role in A˜í‚â§ production and clearance. It has been also shown that RAP binds strongly to A˜í‚â§, leading to an inhibition of A˜í‚â§ aggregation and neurotoxicity. Furthermore, a recent study has shown that the level of RAP expression is significantly decreased in the AD brain compared with healthy controls. This study aimed to identify the region of RAP which binds to A˜í‚â§ and the effect of RAP over-expression and treatment on APP metabolism and A˜í‚â§ production. The possibility that A˜í‚â§ can bind to RAP in the human CSF was also examined. To determine the A˜í‚â§-binding region on RAP, an in-vitro assay was established and validated to study A˜í‚â§-self association, based on the binding of biotin labelled A˜í‚â§42 to synthetic A˜í‚â§42 seeded in the wells of microplates. The A˜í‚â§-binding region on RAP was identified by measuring A˜í‚â§-self association in the presence of different RAP fragments. The results indicated that the A˜í‚â§-binding site was located between amino acid residues 206 and 216 of the RAP sequence in loop region between domains D2 and D3. To examine the effect of RAP on APP metabolism, two strategies were used. The first strategy involved over-expression of RAP in sweAPP-CHO and sweAPP-SH-SY5Y cells, after which the effect of RAP on APP processing and A˜í‚â§ production was analysed. As a second strategy, the effect of RAP on APP metabolism was examined in primary cortical neurons derived from Tg2576 transgenic mice. The results showed that over-expression or treatment of RAP had no significant effect on the level of total APP. However, the levels of sAPP˜í‚â§, C99 and A˜í‚â§ were decreased and the production of C83 was significantly increased in RAP-transfected cells. The results suggest that RAP could decrease A˜í‚â§ production by decreasing ˜í‚â§-cleavage. Therefore, a decreased level of RAP in the brain could contribute to the pathogenesis of AD. Attempts to determine if A˜í‚â§ can bind with RAP in the human CSF were not successful; the preliminary results, however, suggested that Clusterin/CLU is the main A˜í‚â§-binding protein in the human CSF. Taken together, these data suggest that RAP is a protective factor against Alzheimer's disease.

description: We demonstrate spin gradient thermometry, a new general method of measuring the temperature of ultracold atoms in optical lattices. We realize a mixture of spins separated by a magnetic field gradient. Measurement of the width of the transition layer between the two spin domains serves as a new method of thermometry which is observed to work over a broad range of lattice depths and temperatures, including in the Mott insulator regime. We demonstrate the thermometry in a system of ultracold rubidium atoms, and suggest that interesting spin physics can be realized in this system. The lowest measured temperature is 1 nK, indicating that the system has reached the quantum regime, where insulating shells are separated by superfluid layers.

Essays on Market/Mechanism Design

Publisher: name: Carnegie Mellon University

Subjects: Economics

description: We extend the preference domain of the assignment problem to accommodate ordinal, cardinal and mixedpreferences and thereby allow the mechanism designer to elicit different levels of information about individuals’preferences. Given a fixed preference relation over a finite set of alternatives, our domain contains preferences over lotteries that are monotonic, continuous and satisfy an independence axiom. Under a natural coarseness relation, the stochastic dominance relation is the coarsest element of the domain and represents fully ordinal preferences. Any von Neumann-Morgenstern expected utility preference is a finest element and represents fully cardinal preferences. The extended domain can be characterized by an expectedmulti-utility representation. Although it is possible to construct a mechanism in the extended domain wherethe agents with ordinal preferences don’t have an incentive to deviate from truth telling, agents with cardinalpreferences may deviate even if the deviations are restricted to ordinal preference reports.

Upon photoexcitation, the 5T 2 quintet state reveals a charge transfer from the PF 6- ions and from the Fe atoms to neighboring bpy units. The charge transfer from the Fe points to a partial and weak charge-transfer character of this state.

Gibberellins and seed development in Pisum
Creators: name: Swain, SM
Publisher: name: University Of Tasmania
Year: 2023

description: The lhi and ls mutations have been used to investigate the role of the gibberellins (GAs) in seed development of the garden pea (pjsum salivum L.). These mutations were originally identified by their effects on internode elongation. Plants homozygous for lhi or ls possess reduced levels of endogenous GAl in developing shoots, resulting in a dwarf phenotype compared with wild-type plants. The Lh locus has been shown to be linked tO the Le locus at a distance of ca. ScM. In conjunction with wild-type plants and other GA-deficient mutants, lhi, ls and le5839 plants have been used to demonstrate a log-linear relationship between endogenous GAl levels and internode elongation, further supporting a role for GA1 as the major native GA controlling internode elongation is this species. However, the lh' mutation differs from other GA-deficient mutations, such as lh, since the response of lh' plants to paclobutrazol (an inhibitor ofGA-biosynthesis) is dramatically increased. The lh' and ls mutations also reduce endogenous GA levels in developing seeds. This has allowed the site of action of the ls mutation to be identified. Incubation of cell-free enzyme systems from developing wild-type and ls seeds suggests that ls plants possess reduced ent-kaurene synthetase A activity. The lh' mutation also reduces endogenous GA1 and GA3 levels in young seeds (a few days after fertilization), while ls seeds possess similar GA1 and GA3 levels at this stage compared with wild-type seeds. Comparison of GA levels in lh1lh1, lsls, Lsls and wild-type seeds suggests that GA-biosynthcsis may vary within different tissues (embryo, endosperm and testa) of developing seeds. Seeds homozygous for lhi are more likely to abort during development, and weigh less at harvest, compared with wild-type seeds and seeds homozygous for Is. Altering the source/sink relations of developing lhi plants, and 14C-photoassimilate studies, both suggest that lhi seeds possess reduced sink strength compared with wild-type seds. Fertilizing lhi plants with wild-type pollen produces seeds with nonnal GA levels and restores normal seed development. Culturing of lh' embryos with GAl in vitro also increases embryo size. These results have been used to suggest that GAl and GA3 play an important role early in pea seed development. By contrast, the high GA levels found in maturing wild-type seeds do not have a physiological role in seed development.

description: It is generally known that significant improvements in the properties of nanocomposites can be achieved with graphene types currently commercially available. However, so far this is only possible on a laboratory scale. Thus, the aim of this study was to transfer results from laboratory scale experiments to industrial processes. Therefore, nanocomposites based on polyamide (PA) and graphene nanoplatelets (GnP) were prepared in order to produce membranes with improved gas barrier properties, which are characterized by reduced permeation rates of helium. First, nanocomposites were prepared with different amounts of commercial availably graphene nanoplatelets using a semi-industrial-scale compounder. Subsequently, films were produced by compression molding at different temperatures, as well as by flat film extrusion. The extruded films were annealed at different temperatures and durations. In order to investigate the effect of thermal treatment on barrier properties in correlation to thermal, structural, and morphological properties, the films were characterized by differential scanning calorimetry (DSC), wide angle X-ray scattering (WAXS), optical microscopy (OM), transmission electron microscopy (TEM), melt rheology measurements, and permeation measurements. In addition to structural characterization, mechanical properties were investigated. The results demonstrate that the permeation rate is strongly influenced by the processing conditions and the filler content. If the filler content is increased, the permeation rate is reduced. The annealing process can further enhance this effect.
B-mode CMB Polarization from Patchy Screening during Reionization

description: B-modes in CMB polarization from patchy reionization arise from two effects: generation of polarization from scattering of quadrupole moments by reionization bubbles, and fluctuations in the screening of E-modes from recombination. The scattering contribution has been studied previously, but the screening contribution has not yet been calculated. We show that on scales smaller than the acoustic scale (l>300), the B-mode power from screening is larger than the B-mode power from scattering. The ratio approaches a constant ~2.5 below the damping scale (l>2000). On degree scales relevant for gravitational waves (l<100), screening B-modes have a white noise tail and are subdominant to the scattering effect. These results are robust to uncertainties in the modeling of patchy reionization.

description: We study the symmetries of pure N=2 supergravity in D=4. As is known, this theory reduced on one Killing vector is characterised by a non-linearly realised symmetry SU(2,1) which is a non-split real form of SL(3,C). We consider the BPS brane solutions of the theory preserving half of the supersymmetry and the action of SU(2,1) on them. Furthermore we provide evidence that the theory exhibits an underlying algebraic structure described by the Lorentzian Kac-Moody group SU(2,1)^{+++}. This evidence arises both from the correspondence between the bosonic space-time fields of N=2 supergravity in D=4 and a one-parameter sigma-model based on the hyperbolic group SU(2,1)^{++}, as well as from the fact that the structure of BPS brane solutions is neatly encoded in SU(2,1)^{+++}. As a nice by-product of our analysis, we obtain a regular embedding of the Kac-Moody algebra su(2,1)^{+++} in e_{11} based on brane physics.

description: Fields in spacetime could be simultaneously discrete and continuous, in the same way that information can: it has been shown that the amplitudes, ϕ(x_n), that a field takes at a generic discrete set of points, x_n, can be sufficient to reconstruct the field ϕ(x) for all x, namely if there exists a certain type of natural ultraviolet (UV) cutoff in nature, and if the average spacing of the sample points is at the UV cutoff scale. Here, we generalize this information-theoretic framework to spacetimes themselves. We show that samples taken at a generic discrete set of points of a Euclidean-signature spacetime can allow one to reconstruct the shape of that spacetime everywhere, down to the cutoff scale. The resulting methods could be useful in various approaches to quantum gravity.

Multiculturalism and identity: A visual investigation through the medium of printmaking

Publisher: name: University Of Tasmania

description: The catalyst for this project has been my father's migration from Croatia to Australia in the 1950's and my experience of his European heritage within my Australian environment. My father and the material artefacts he brought from Croatia, such as photographs and textiles, created a small but strong presence of this heritage for me within my family and the domestic interior of my home. From the moment I recognised their 'difference', which had been disguised by their familiarity as objects that were part of my daily life, and saw them as representations of the exotic, their presence intensified. They have since been the object of my curiosity and desire- a curiosity with the familiar made strange; and a desire to know more about their original context: the past, the homeland, and the people depicted in the photographs. My connection to this heritage is via these artefacts and is enriched by my father and his stories, memories and descriptions that project an idealised version of his homeland. This project investigates these artefacts as forms of representation from which knowledge and perception of the homeland are derived for the first-generation. An important aspect of the project is the migrant and his/her verbal testimony which is integral to the development of the first-generation's perspective since it is the migrant's idealised version of the homeland that is passed down to and explored by their children. The artefacts are a tangible connection to the past and the homeland. They are explored as the only means of access to that world for the firstgeneration, who have no first-hand experience of the actual place. This project is autobiographical in that it stems from my own personal experience, although it is also representative of the dilemma faced by all first-generation children of migrants. It reveals an unbridgeable distance between the place that was left by the migrant and the concept of the homeland from the perspective of the firstgeneration. The significance of this research is where my works have reinvented the artefacts and their specific cultural references, changing and distorting them, rather than simply illustrating them, incorporating them visually, as if to reclaim a repressed heritage or a lost history. It is the way in which the source material is manifest in the work, in their distorted form, which can be seen as a sign of this repression and the irretrievable past The nature of the works submitted reveals an obsession that characterises the position of the first-generation - an obsession that is entirely dependent on the futile pursuit of the homeland. The outcomes of this investigation reveal the first-generation's perception of the homeland to be their own fetishised projection which is the result of the lack or absence of materials and knowledge from which they can build up and develop their own exploration of their cultural heritage.

description: "During the entire period from about 1950 to 2005 the Kopia and Kubuka tribes, with whom we have lived at Kailge, were not involved in any lethal warfare. They were on the verge of it in 1982 when they joined in with their eastern neighbours - the Epola-Alya and others - in a fight that had broken out between them and their neighbours to the south, the Tea-Dena. This conflict (for reasons discussed in Merlan & Rumsey 1991) became known as the Marsupial Road War (see Map 3). But that war was stopped by a dramatic intervention by a local women’s group who marched out on the battlefield between the opposing sides and broke it up. That intervention established a peace that lasted 23 years. This changed dramatically in 2005 when the Kopia and Kubuka people got into the biggest fight that they had experienced in living memory in which approximately 80 people were killed over then period 2005-2007. Here I give an account of how that turn of events took place, use it to illustrate what I see as some general features of the socio-political order in this region, and try to develop some conclusions about the problems and prospects for conflict resolution there and in Highland New Guinea more generally ..." - page 1-2
Human participants in AI research: Ethics and transparency in practice

description: In recent years, research involving human participants has been critical to advances in artificial intelligence (AI) and machine learning (ML), particularly in the areas of conversational, human-compatible, and cooperative AI. For example, roughly 9% of publications at recent AAAI and NeurIPS conferences indicate the collection of original human data. Yet AI and ML researchers lack guidelines for ethical research practices with human participants. Fewer than one out of every four of these AAAI and NeurIPS papers confirm independent ethical review, the collection of informed consent, or participant compensation. This paper aims to bridge this gap by examining the normative similarities and differences between AI research and related fields that involve human participants. Though psychology, human-computer interaction, and other adjacent fields offer historic lessons and helpful insights, AI research presents several distinct considerations$\unicode{x2014}$namely, participatory design, crowdsourced dataset development, and an expansive role of corporations$\unicode{x2014}$that necessitate a contextual ethics framework. To address these concerns, this manuscript outlines a set of guidelines for ethical and transparent practice with human participants in AI and ML research. Overall, this paper seeks to equip technical researchers with practical knowledge for their work, and to position them for further dialogue with social scientists, behavioral researchers, and ethicists.

title: Relationship of the Soil Water Content and Microclimate to the Plant Growth Water Use Relationship of Several Plants
Creators: name: Sandberg, Philip Dean
Publisher: name: Utah State University
Year: 1971

description: Studies involving field plots, lysimeters, and garbage can lysimeters showed that an intermediate soil water level produced the most growth for a given amount of water use by oats, corn, and barley. For crested wheatgrass the lowest water level produced the most growth per water used. Field plots which were covered with sheet metal between the rows produced more plant growth per water used than the uncovered plots for the crops used in this study. One year's data were obtained on the effect of positioning the garbage can lysimeters. One half of the cans were placed on the soil surface and the other half were sunken into the soil, level with the soil surface. The data indicate no difference in water use efficiency between the two positions of the can. A new method was used to obtain garbage can size soil cores that were relatively undisturbed.
The data for the field plots indicates that the field plots were more efficient in water use than the lysimeters; however, there are indications that all the water used by the field plots were not measured. A review of the literature on water use efficiency indicated the field values from this study were probably too high. It was possible that the roots were extracting water below the measuring depth or that the water was moving up through the profile in the field plots and the lysimeters (or cans) were the same, showed that the field plots could have received up to about 21 centimeters (cm) of water not accounted for in the soil depletion measurement.
Education for planning : the special circumstances in low income countries
Creators: name: Viloria, Leandro A.
Publisher: name: University of British Columbia

description: This study deals with the problem of seeking logical strategies for establishing educational programs on community planning in various categories of poor countries. Its thesis is that education for community planning in poor countries, to be effective, must relate to the development process at all levels of government and to the educational system. Two assumptions have been made: (1) Each of the poor countries must evolve its own program of manpower education, in which community planning education is but a part, in the light of its social and economic goals; and (2) Education for community planning in a poor country must interlock with its social and economic planning process. Two steps have been employed to prove or disprove this thesis. Initially, a set of logical strategies for establishing an educational system in poor countries has been formulated. Three levels of development have been considered and an appropriate set of strategies have been designed for each. Then this construct has been tested through two case studies. The case studies cover Ghana and Indonesia. In Ghana, an attempt is being made to produce local planning assistants. On the other hand, a professional program with a focus on regional planning has been established in Indonesia. Both programs are pioneering efforts. Both programs have been initiated under United Nations technical assistance. Both programs have been aided by a North American university; Ghana by the University of British Columbia and Indonesia by Harvard University. Considering the level of development of both countries, this study finds both programs as too ambitious and therefore too premature. Based on this study's set of logical strategies, Ghana and Indonesia should have concentrated on the education of planning assistants. In the meantime, the positions of professional planners should be filled by expatriate personnel. At the same time, selected nationals should be sent abroad for professional education. With a firm foundation of a planning assistants course, its extension towards professional education could proceed in a logical manner as the country's level of development improves. To poor countries contemplating to establish planning educational systems, this study offers a set of guidelines. These guidelines consist of two parts. The first part provides a framework for approaching the formulation of an educational program on a comprehensive basis. The second part relates how the comprehensive approach may be realized. These guideline, hopefully, will be refined as others would conduct further studies on the experiences of the rest of the countries which have inaugurated planning educational programs.

This approach can be considered as a first step towards the characterization of realistic interacting decaying systems, an archetypal process in physics. The results presented here also suggest the possibility of manipulating correlations using external fields, a technique that could be useful to provide sources of entangled massive particles.

description: We consider the generalization of the heterotic action considered by Cherkis and Schwarz where the chiral bosons are introduced in a manifestly covariant way using an auxiliary field. In particular, we construct the kappa-symmetric heterotic action in ten-dimensional supergravity background coupled to super Yang-Mills theory and prove its kappa-symmetry. The usual Bianchi identity of Type I supergravity with super Yang-Mills $dH_3= -\tr F\wedge F$ is crucially used. For technical reason, the Yang-Mills field is restricted to be abelian.

Lung function and cardiovascular risk in young adults
Creators: name: Curry, BA
Publisher: name: University Of Tasmania

description: Associations between poor lung function (LF) and cardiovascular disease (CVD) have been reported in patients with chronic obstructive pulmonary disease and in population samples of older adults, including lifelong non-smokers. There are few studies of this association in young adults. Common modifiable risk factors for poor LF and CVD that might explain the association include smoking, low levels of physical activity, low cardiorespiratory fitness (CRF) and obesity. Systemic inflammation indicated by markers such as C-reactive protein (CRP), might also be explanatory. Aim The aims of this study were: 1) to investigate the cross-sectional and longitudinal associations of modifiable CVD risk factors with adult LF and 2) to investigate cross-sectional associations of young adult LF with CRP and carotid artery structure and function as subclinical indicators of atherosclerosis. Methods Data for this study were obtained from sub-samples of 2,410 participants of the 1985 Australian Schools Health and Fitness Survey who had follow up health assessments between 2004-2006 when aged 26-36 years of age. Data from at least 1,700 participants were used to investigate cross-sectional associations of smoking, CRF, adiposity and CRP with adult LF (forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). Longitudinal data were also examined to determine the effects on adult LF of: childhood and parental smoking (in 278 daily and 1,515 never smokers respectively), poor childhood CRF and obesity (among approximately 600 participants with baseline data). Associations between adult lung function and ultrasound measures of carotid intima-media thickness (cIMT) and arterial elasticity were also assessed. Results Adult smokers had higher mean lung volumes than non-smokers. Among daily smokers, cumulative cigarette exposure and childhood smoking had significant independent negative effects on adult LF. Higher CRF was positively associated with LF and was independent of adiposity among females. Adiposity was negatively associated with LF. Adult fitness and adiposity were much more strongly associated with adult LF than were childhood measures.Weak negative associations between CRP and adult LF were observed which were stronger in participants with greater than average adiposity. Lower FEV1 and FVC in female never-smokers and lower FEV1/FVC in ever-smoking males were associated with thicker cIMT, but the latter associations were confounded by cumulative smoke exposure. No independent associations between lung function and arterial elasticity were observed for males or females. Conclusion Overall, adiposity was more strongly associated with LF than either smoking, CRF or CRP. In these young adults, there was little evidence of an independent association between LF and subclinical atherosclerosis in males. However, a significant association between LF and cIMT was evident for female never smokers independent of other known CVD risk factors.

description: The problems of phosphate fertilization have attracted the attention of agronomists, nutritionists, and other biological scientists due to the importance of phosphorus in animal and plant nutrition. However, the fundamental behavior of phosphorus in soil systems is not well understood. Because of its far-reaching effects, a solution of a portion of this problem is of importance.

description: This paper introduces two operations in quiver gauge theories. The first operation takes a quiver with a permutation symmetry $S_n$ and gives a quiver with adjoint loops. The corresponding 3d $\mathcal{N}=4$ Coulomb branches are related by an orbifold of $S_n$. The second operation takes a quiver with $n$ nodes connected by edges of multiplicity $k$ and replaces them by $n$ nodes of multiplicity $qk$. The corresponding Coulomb branch moduli spaces are related by an orbifold of type $\mathbb{Z}_q^{n-1}$. The first operation generalises known cases that appeared in the literature. These two operations can be combined to generate new relations between moduli spaces that are constructed using the magnetic construction.

How one becomes what one is

Publisher: name: University of British Columbia

description: In this essay, I explain what Nietzsche meant by saying "God is dead," and what he thought this Implied for the European morality of his day. The first section deals with the doctrine of eternal recurrence. The doctrine is outlined by means of the two main passages that Nietzsche devotes to the physical details in the books published by him. It is then indicated how seriously Nietzsche took eternal recurrence. I proceed by questioning the scientific soundness of the doctrine, but conclude the section by pointing out the significance that eternal recurrence would have had, had it been true. The most important consequence of the doctrine of eternal recurrence, to Nietzsche, is that it would have overthrown the Christian God, worldview, and morality. Section two proceeds to establish that for Nietzsche and us, even without the doctrine of eternal recurrence, the Christian God has died. I show that we still pride ourselves on being Christians, but I then go on to indicate that we lack the beliefs that would make us true Christians. The main conclusion established in this section is that science and rationalism have killed God. In the third section, I outline the significance of God's death by showing how, with the removal of God, the Christian morality and worldview are left without foundation. I then begin to point out the freedom which man has thereby received. I show that certain concepts and certain metaphysical views can no longer be employed without a severe shift in meaning. I conclude by observing that man does not need to be ashamed of himself anymore. God's death is examined further, in the fourth section, through the implications it has for the passions. It is shown that God's death serves first of all as a means to remove a number of stupidities relating to the nature of the passions. The stupidities of thinking the passions horrendous and of thinking that the only method to cope with the passions is extirpation are examined, and then dismissed. I finish by indicating that a mastering and conquering of the passions is a necessary prerequisite to become master in anything at all. The fifth and final section re-introduces the doctrine of eternal recurrence to show how it led Nietzsche to see the man seeking self-perfection as the best example of a means to deal with the pains and miseries of life. It is then shown how this ideal serves the same function for the person rejecting the eternal recurrence doctrine but not the view that God is dead. To see how one's life can be conceived as an aesthetically pleasing whole, an autobiographical note of Nietzsche and his remarks about Goethe are examined. Certain Nietzschean concepts are discussed in their relation to the man who seeks self-perfection, to show how this goal can be achieved. I conclude the section by indicating that one's life can be seen as forming an aesthetically pleasing whole by having a "dominant task" being brought to our awareness through our "organizing 'idea'."

description: In this Letter we analyze the coexisting ordered phases that arise in the half-filled $\varepsilon$-t-U-V extended Hubbard Model on the square lattice when tackled within the Kotliar andRuckenstein slave boson representation in the thermodynamical limit. Particular emphasis is put on the dependence of the quasiparticle dispersions, the gaps, the spin-resolved renormalization factors, and the distribution of double occupancy on the microscopical parameters of the model. Our calculations are performed in a parameter range that is most suitable for resistive switching. In particular, the main contributions to the gaps are shown to either arise from $\varepsilon$ in the weak coupling regime, or from U and V when they are the largest scales. The gaps are thus from joint spin and charge origin, and so are the order parameters.
