description: We apply the recently formulated torque equilibrium spin wave theory (TESWT) to compute the $1/S$-order interacting $K$ -edge bimagnon resonant inelastic x-ray scattering (RIXS) spectra of an anisotropic triangular lattice antiferromagnet with Dzyaloshinskii-Moriya (DM) interaction. We extend the interacting torque equilibrium formalism, incorporating the effects of DM interaction, to appropriately account for the zero-point quantum fluctuation that manifests as the emergence of spin Casimir effect in a noncollinear spin spiral state. Using inelastic neutron scattering data from Cs$_2$CuCl$_4$ we fit the 1/S corrected TESWT dispersion to extract exchange and DM interaction parameters. We use these new fit coefficients alongside other relevant model parameters to investigate, compare, and contrast the effects of spatial anisotropy and DM interaction on the RIXS spectra at various points across the magnetic Brillouin zone. We highlight the key features of the bi- and trimagnon RIXS spectrum at the two inequivalent rotonlike points, $M(0,2 π/\sqrt{3})$ and $M^{\prime}(π,π/\sqrt{3})$, whose behavior is quite different from an isotropic triangular lattice system. While the roton RIXS spectrum at the $M$ point undergoes a spectral downshift with increasing anisotropy, the peak at the $M^\prime$ location loses its spectral strength without any shift. With the inclusion of DM interaction the spiral phase is more stable and the peak at both $M$ and $M^\prime$ point exhibits a spectral upshift. Our calculation offers a practical example of how to calculate interacting RIXS spectra in a non-collinear quantum magnet using TESWT. Our findings provide an opportunity to experimentally test the predictions of interacting TESWT formalism using RIXS, a spectroscopic method currently in vogue.

description: The synthesis of transition metal dichalcogenides (TMDs) are crucial to realization of their real-world applications in electronic, optoelectronic and chemical devices. However, the fabrication yield in terms of material quality, crystal size, defect density are poorly controlled. In this work, by employing the up-to-date stack-and-transfer and nano fabrication techniques, synthetic TMDs that obtained from different growth methods with various crystal qualities were studied. In most of the cases, better crystals with lower defect densities and larger crystal domain sizes are preferred. Self-flux method was developed to obtain better quality crystals comparing to the traditional chemical vapor transport, as characterized by lower defect densities. BN encapsulating graphene device platform was utilized and TMDs monolayers with different defect densities was inserted in between the BN/graphene interface, where intrinsic defects from the TMDs disturbed the electronic environment of graphene. With the better TMD crystal insertion, we obtain much better electrical performed device in terms of hysteresis, FWHM of Dirac peak and electron mobility. This device also showed advantage in quantum transport measurements . On the other hand, the presence of defects are not always undesired, especially when it comes to serve as electrocatalysts, in which most of the reactions take place at vacancy sites. However, similar to most of the MoS2 electronic devices, forming barrier-free metal semiconductor contact is the major challenge. We develop a platform that contact resistance could be monitored simultaneously with electrochemical activity. In this platform, the total device resistance is significantly reduced before electrochemical reaction happens while the intrinsic catalytic activity of the MoS₂ can be extracted. With this platform, we found the intrinsic catalytic activity of MoS₂ strongly correlated to H-coverage on its surface. By adding molecular mediator into electrolytes, H-coverage and the resulting HER activity was enhanced via “Catch and Release” mechanism. Molecular simulation was performed to support our experimental results.

description: It has been known since the beginning of this century that isomonodromic problems --- typically the Painlevé transcendents --- in a suitable asymptotic region look like a kind of ``modulation'' of isospectral problem. This connection between isomonodromic and isospectral problems is reconsidered here in the light of recent studies related to the Seiberg-Witten solutions of $N = 2$ supersymmetric gauge theories. A general machinary is illustrated in a typical isomonodromic problem, namely the Schlesinger equation, which is reformulated to include a small parameter $ε$. In the small-$ε$ limit, solutions of this isomonodromic problem are expected to behave as a slowly modulated finite-gap solution of an isospectral problem. The modulation is caused by slow deformations of the spectral curve of the finite-gap solution. A modulation equation of this slow dynamics is derived by a heuristic method. An inverse period map of Seiberg-Witten type turns out to give general solutions of this modulation equation. This construction of general solution also reveals the existence of deformations of Seiberg-Witten type on the same moduli space of spectral curves. A prepotential is also constructed in the same way as the prepotential of the Seiberg-Witten theory.

description: The franchise model has transformed modern retailing and the economic effects have been experienced on an international scale. Although the contemporary approach to franchising was only developed half a century ago, it has quickly evolved into a highly effective, profitable and widely adopted business strategy, particularly in the Australian market. Despite the current profusion of franchising and the potential for continued growth, fundamental questions about the management of people in these organisations remain relatively unexplored. Franchising presents a unique composition of autonomy and control. The autonomy of franchisees is located midway between that of employed managers and independent business owners, while the powerful franchisor controls core business processes such as marketing and product development. Although agency theory suggests that heavy franchisor control over certain functions is integral to the success of the franchise model, the applicability of this concept to human resource management (HRM) is unclear. This thesis addresses research deficiencies at the junction of HRM and franchising through three research questions: how is the approach to HRM enacted in the franchise relationship; what factors influence the approach to HRM in the franchise relationship, and; what are the implications of the approach to HRM for franchisees? The HR department is critical to determining the approach an organisation adopts to managing human resources. In this thesis, the work conducted by the HR department was identified and classified according to existing models, enabling comparisons with the roles performed in more traditional organisations. Determination of these roles was regarded as an outcome of the strategic decision-making process, influenced by certain contextual variables. Accordingly, this thesis considers how strategic HRM decision-making in franchises is impacted by internal and external factors determined by an extensive review of the relevant literature.

description: The effect of ferroelectric fluctuations on the temperature dependent dielectric constant of SrTiO$_3\,$(STO) has been long studied. Those fluctuations have been shown in recent years to be quantum critical and STO demonstrated to form the archetypal quantum critical paraelectric. The effect of those same fluctuations on the pressure and temperature dependence of the ferroelectric soft phonon mode as the system is tuned away from criticality are reported for the first time in this paper. We show that the mean field approximation is confirmed experimentally. Furthermore, using a self-consistent model of the quantum critical excitations including coupling to the volume strain and without adjustable parameters, we determine logarithmic corrections that would be observable only very close to the quantum critical point. Thus, the mean-field character of the pressure dependence is much more robust to the fluctuations than is the temperature dependence. We predict stronger corrections for lower dimensionalities however. The same calculation confirms that the Lydanne-Sachs-Teller relation is valid over the whole pressure and temperature range considered. Therefore, the measured dielectric constant can be used to extract the frequency of the soft mode down to 1.5 K and up to 20 kbar of applied pressure. The soft mode is observed to stiffen further, raising the low-temperature energy gap and returning towards the expected shallow temperature dependence of an optical mode. This behavior is consistent with the existence of a quantum critical point on the pressure-temperature phase diagram of STO, which applied pressure tunes the system away from. This work represents the first experimental measurement of the stiffening of a soft phonon mode as a system is tuned away from criticality, a potentially universal phenomenon across a variety of phase transitions and systems in condensed matter physics.

description: We study the potential of high-energy linear $e^+e^-$ colliders for the production of gluino pairs within the Minimal Supersymmetric Standard Model (MSSM). In this model, the process $e^+e^-\to\tilde{g}\tilde{g}$ is mediated by quark/squark loops, dominantly of the third generation, where the mixing of left- and right-handed states can become large. Taking into account realistic beam polarization effects, photon and $Z^0$-boson exchange, and current mass exclusion limits, we scan the MSSM parameter space for various $e^+e^-$ center-of-mass energies to determine the regions, where gluino production should be visible.

description: In this paper we provide an overview on the foundation and first results of a very recent quantum theory of color perception, together with novel results about uncertainty relations for chromatic opposition. The major inspiration for this model is the 1974 remarkable work by H.L. Resnikoff, who had the idea to give up the analysis of the space of perceived colors through metameric classes of spectra in favor of the study of its algebraic properties. This strategy permitted to reveal the importance of hyperbolic geometry in colorimetry. Starting from these premises, we show how Resnikoff's construction can be extended to a geometrically rich quantum framework, where the concepts of achromatic color, hue and saturation can be rigorously defined. Moreover, the analysis of pure and mixed quantum chromatic states leads to a deep understanding of chromatic opposition and its role in the encoding of visual signals. We complete our paper by proving the existence of uncertainty relations for the degree of chromatic opposition, thus providing a theoretical confirmation of the quantum nature of color perception.

description: Models of the decoupling of baryons and photons during the recombination epoch predict the existence of a large-scale velocity offset between baryons and dark matter at later times, the so-called streaming velocity. In this paper, we use high resolution numerical simulations to investigate the impact of this streaming velocity on the spin and shape distributions of high-redshift minihalos, the formation sites of the earliest generation of stars. We find that the presence of a streaming velocity has a negligible effect on the spin and shape of the dark matter component of the minihalos. However, it strongly affects the behaviour of the gas component. The most probable spin parameter increases from $\sim$0.03 in the absence of streaming to $\sim$0.15 for a run with a streaming velocity of three times $σ_{\rm rms}$, corresponding to 1.4 km\,s$^{-1}{}$ at redshift $z=15$. The gas within the minihalos becomes increasingly less spherical and more oblate as the streaming velocity increases, with dense clumps being found at larger distances from the halo centre. The impact of the streaming velocity is also mass-dependent: less massive objects are influenced more strongly, on account of their shallower potential wells. The number of halos in which gas cooling and runaway gravitational collapse occurs decreases substantially as the streaming velocity increases. However, the spin and shape distributions of gas that does manage to cool and collapse are insensitive to the value of the streaming velocity and we therefore do not expect the properties of the stars that formed from this collapsed gas to depend on the value of the streaming velocity. The spin and shape of this central gas clump are uncorrelated with the same properties measured on the scale of the halo as a whole.

description: It is thought that Galactic cosmic ray (CR) nuclei are gradually accelerated to high energies (up to ~300 TeV/nucleon, where 1TeV=10^12eV) in the expanding shock-waves connected with the remnants of powerful supernova explosions. However, this conjecture has eluded direct observational confirmation^1,2 since it was first proposed in 1953 (ref. 3). Enomoto et al.^4 claim to have finally found definitive evidence that corroborates this model, proposing that the very-high-energy, TeV-range, gamma-rays from the supernova remnant (SNR) RX J1713.7-3946 are due to the interactions of energetic nuclei in this region. Here we argue that their claim is not supported by the existing multiwavelength spectrum of this source. The search for the origin(s) of Galactic cosmic ray nuclei may be closing in on the long-suspected supernova-remnant sources, but it is not yet over.

17 MeV Atomki anomaly from short-distance structure of spacetime
Creators: name: Nam, Cao H.
Publisher: name: arXiv
Year: 2019
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: An anomaly observed recently in the $^8$Be nuclear transition by the Atomki collaboration hints at a weakly-coupled, light new gauge boson with a mass of about $17$ MeV. In this paper, we propose that this new gauge boson comes from a short-distance structure of the spacetime, rather than from an extension of the Standard Model through adding an extra $\mathrm{U}(1)$ gauge symmetry. The dominant contribution to the relevant matrix element of the $^8$Be nuclear transition is given by the axial couplings. In order to account for the $^8$Be anomaly and satisfy the current experimental constraints, the coupling constant of the new gauge boson should be about $\mathcal{O}(10^{-4}-10^{-5})$. Our theoretical model allows understanding the origin of the smallness of the coupling constant, which is still missing or being incompletely understood in the models at which the new gauge boson has the axial couplings.

A general solution of the bilinear equations is presented.

Causal Mediation Analysis for Effect Heterogeneity

subject: Public health

description: It is possible to quantify and understand how an exposure affects an outcome through an intermediate variable via causal mediation analysis. In many cases in practice, however, the effect of the exposure may vary for different subgroups of the population. Combining these two ideas results in the related concepts of moderated mediation and mediated moderation. Addressing questions of why and how an exposure gives rise to an outcome differently for different subsets of the population provides deeper understandings of the effect heterogeneity phenomenon and permits insights that may be both clinically and practically meaningful about what works for whom and through which intermediate(s).This dissertation explores how to understand and explain these causal mechanisms by focusing on explaining effect heterogeneity via causal mediation analysis. Formal definitions and analytical formulas for direct and indirect effect heterogeneity measures are described from a counterfactual perspective. Various types of direct and indirect effect heterogeneity from two-way and three-way decompositions, such as natural direct and indirect effect heterogeneity and pure direct and indirect effect heterogeneity, are introduced and defined. However, just simply decomposing the total effect heterogeneity into direct and indirect effect heterogeneity does not fully account for the complex mechanism of the two-way and three-way interactions happening in the effect heterogeneity phenomenon. Arising from this, in the context of a regression-based approach, this dissertation shows how direct and indirect effect heterogeneity can be further decomposed to account for possible multi-way interactions between exposure, mediator, and modifier. This is an essential way to account for different portions of interactions along causal pathways of effect heterogeneity. It provides more causal implications about the question for whom and in what context that the effect happens. Identification assumptions that are sufficient for the estimations of effect heterogeneity decompositions are also considered. Analytical expressions for effect heterogeneity decompositions on additive and ratio scales are provided. National Longitudinal Study of Adolescent to Adult Health (Add Health) data is used to illustrate the proposed methodologies in application.

As an application, we completely determine the largest minimum weights for dimension $3$, by using a classification of some quaternary codes. In addition, for a positive integer $s$, a maximal entanglement entanglement-assisted quantum $[[21s+5,3,16s+3;21s+2]]$ codes is constructed for the first time from a quaternary Hermitian linear complementary dual $[26,3,19]$ code.

description: For years, RNAs were thought to have only two broad functions in cells, transmitting information between DNA and protein as messenger RNA (mRNA), and playing structural, catalytic, information decoding roles in protein synthesis as ribosomal RNA (rRNA) and transfer RNA (tRNA). However, the discovery of RNA interference (RNAi) changed this picture. RNAi is a regulatory process that uses small non-coding RNAs (ncRNAs) to suppress gene expression at the post-transcriptional level. This discovery led to identification of many classes of functional ncRNAs. MicroRNA (miRNA) is a class of such ncRNAs with ∼22 nucleotides that are quite abundant and found in most eukaryotic cells. This thesis focuses on revealing regulatory roles and characteristics of miRNAs through bioinformatics approaches by addressing three research questions. The first research question is whether we can enhance miRNAs target prediction in animals by considering multiple target sites. Many algorithms exist for miRNA target predictions, but most algorithms do not consider multiple target sites. Predicting accurate miRNA target genes is important to infer miRNA regulatory roles since annotations of miRNA regulations are poor. To solve this possible fault, we developed a two step support vector machine (SVM) model. Benchmark tests showed that our two step model outperformed other existing miRNA target prediction algorithms. The second research question is whether there are factors to explain differences between different miRNA high-throughput experiments. There are several high-throughput technologies widely used for miRNA experiments, such as microarray and quantitative proteomics, but the results from these technologies are often inconsistent. By statistically analyzing several such high-throughput miRNA experiments, we revealed the characteristic of different technologies and also identified several factors that cause the differences. The third research question is whether miRNAs interact with other classes of ncRNAs. There are strong evidences that some miRNAs are involved in transcription by interacting with other ncRNAs. We investigated ncRNAs in complex loci to find potential miRNA:ncRNA interactions. A complex locus is a locus that contains multiple genes that interact between themselves. We found evidence that some miRNAs are involved in transcriptional regulation with ncRNAs in complex loci. In summary, this thesis provides solutions for these research questions, and it contributes to a better understanding of several important aspects of miRNA characteristics and regulations. It also shows effective bioinformatics approaches to develop a robust machine learning model and analyze different miRNA high-throughput experiments.

description: Introduction: The implementation of a publicly-funded immunization program results from a complex decision-making process. John Kingdon’s ‘Multiple Streams Framework’ has been extensively used to analyze how and why governmental policies were adopted. Area covered: Ideas that will ultimately end up in a proposal for a new immunization program develop gradually along three main streams: (i) the problem stream, which focuses on a particular vaccine-preventable disease and its perception by stakeholders; (ii) the policy stream, which is centered on experts’ views on the optimal use of available vaccines; and (iii) the politics stream, which consists of socio-political factors, including budgetary constraints. Ideas are progressively shaped by policy entrepreneurs into a proposal with concrete implementation strategies. The three streams then converge within a policy window, during which adoption is especially likely to occur. To survive, the proposed program should be operationally feasible, consistent with mainstream social values, and financially affordable. The timing of the policy window is usually unpredictable and of short duration. Expert opinion: Analytical frameworks traditionally used to assess immunization programs focus on the technical aspects of the disease, the vaccine, and the program. The ‘Multiple Streams Framework’ brings added analytical value by enlarging the scope of the analysis into the political arena.

description: Topological nodal line semimetals host stable chained, linked, or knotted line degeneracies in momentum space protected by symmetries. In this paper, we use the Jones polynomial as a general topological invariant to capture the global knot topology of the nodal lines. We show that every possible change in Jones polynomial is attributed to the local evolutions around every point where two nodal lines touch. As an application of our theory, we show that nodal chain semimetals with four touching points can evolve to a Hopf-link. We extend our theory to 3D non-Hermitian multi-band exceptional line semimetals.

description: Popular portrayals of drug-using mothers claim that they are just "not into mothering" or that they leave their children to "fend for themselves" in their relentless pursuit of their own pleasures. Yet a deeper reading of these statements, and others like them reveals that they are not simply a judgment on this specific group of deviant women, but form part of a continuum of strictures informing all women about what is expected of them as women and as mothers. They lay the foundation for the enforcement of particular modes of behavior for women, for pregnant patients and for mothers. In an attempt to explore how the cultural imperatives of mothering are influenced by the cultural strictures against drug use and drug users, this ethnography explored the lives of 14 drug-using mothers in the comparatively supportive environment of Manchester in the United Kingdom. Over the course of three years of fieldwork and in-depth interviewing two major themes emerged: Control and Fluidity. Control was most apparent in the persistent tension between the women's self-imposed need for control (over her body, her children, her drugs and herself) and the control both demanded and imposed by the state agencies that work with her. Fluidity, particularly of the mothering identity, quickly emerged as a key aspect of women's lives and their understanding of self. Drug-using mothers are criticized for supposedly violating the bonds of the mother-child relationship, but the bonds are already frayed by a system that forces them to confront the possibility of child loss before the child is even born. To capture the shifts in meaning and experience of motherhood for this population I developed a descriptive model that categorizes their experience of the mothering identity through the filter of child-loss: The Conspicuous Mother, The Latent Mother and The Abnegate Mother. The model shows that child-loss is not an all-or-nothing experience for these women, and goes some way toward understanding why, when some women lose their children they "go off the rails" while others use child loss as an opportunity for getting their lives back on track. The study also makes clear that in order to create sustainable change we must move beyond the notion that drug-use invariably leads to neglect and focus instead on creating systemic change in the women's lives, not just their drug-taking.

description: This research verifies the effects of incorporating the ToGatherUp tool on both time and effort for building manually the corpus presented herein: the Corpus of Computing in English (CoCLI). We have developed a set of effort measurement metrics – Activity Effort (EA), Total Effort for Text Collection (ETCT) and Total Project Effort (ETP) – which served as the basis for conducting a comparative statistical experiment between the manual elaboration of two identical versions of the CoCLI: which differ from each other by one of them using the ToGatherUp and the other one not using it. The theory and methodology of Corpus Linguistics, together with the concepts from Project Management, subsidized our proposal of systematizing the manual construction of corpora and for creating the two versions of the CoCLI and, along with the notions of the Computing area, guided us in the development of ToGatherUp. The experiment shows an average reduction of 7.47% in the ETP when using ToGatherUp compared to the ETP when not using the tool. This result corroborates the hypothesis that the tool reduces the time and effort spent by the researcher on manual elaboration projects of corpora.
Padé-based arbitrary wavelength polarization closures for full-F gyro-kinetic and -fluid models

description: We propose a solution to the long-standing short wavelength polarization closure shortfall of full-F gyro-fluid models. This is achieved by first finding an appropriate quadratic form of the gyro-fluid moment over the polarization part of the gyro-center Hamiltonian. Secondly, we deduce Padé-based approximations to the latter expression that produce a polarization charge density with the desired order of accuracy and retain linear polarization effects for arbitrary wavelengths. The proposed closures feature proper energy conservation and the anticipated Oberbeck-Boussinesq and long wavelength limits.
Kinetics of the disordered Bose gas with collisions

description: We discuss the kinetics of the disordered interacting Bose gas using the Boltzmann transport equation. The theory may serve as a unifying framework for studying questions of dynamics of the expanding Bose gas at different stages of the expansion. We show that the transport theory allows us to straightforwardly reproduce and generalize a number of results previously obtained from microscopic models in different formalisms. Based on estimates for the interparticle scattering rates, we discuss the relevance of interaction effects for the localization problem in the interacting disordered Bose gas. We argue that, if the number of particles is large enough, the size of the expanding cloud may exceed the localization length. We describe the spreading of the wave packet in this regime as collision-induced diffusion and compare the obtained rate of expansion to known results on subdiffusive spreading in nonlinear disordered lattices.

description: In this paper we make a systematic use of the quantum measurement theory to describe perceived colors and analyze some of their fundamental properties. After motivating the naturalness of the quantum measurement approach in the mathematical framework of the color perception theory proposed by the authors in previous papers, we show how to obtain several results. Among our theoretical outcomes, we mention the possibility to confine the color cone to a finite-volume color solid and the link between post-measurement state changes, Lorentz boosts and the Einstein-Poincaré relativistic addition law. We apply these results to obtain a chromatic match equation that emphasizes the importance of the Hilbert-Klein metric on the unit disk and we also present a quantitative description of Hunt's effect.

description: Using spectroscopic ellipsometry we investigated and analyzed the pseudo- optical constants of Cu 2ZnSnSe4 bulk crystals, grown by the Bridgman method, over 0.8–4.5 eV photon energy range. The structures found in the spectra of the complex pseudodielectric functions were associated to E0, E1A, and E1B interband transitions and were analyzed in frame of the Adachi's model. The interband transition parameters such as strength, threshold energy, and broadening were evaluated by using the simulated annealing algorithm. In addition, the pseudo-complex refractive index, extinction coefficient, absorption coefficient, and normal-incidence reflectivity were derived over 0.8–4.5 eV photon energy range.

title: An Examination of intermittent Hypoxia Exposure on Key Haematological and Immune-Stress Responses in Normally Active Humans
Creators: name: Tobin, Barbara
Publisher: name: Griffith University
Year: 2013
Subjects: subject: Hypoxia
subject: Altitude acclimatization
subject: Intermittent hypoxia exposure

description: Altitude is one naturally occurring source of low oxygen levels (hypoxia) and altitude acclimatization has been utilized to trigger cellular protection in elite athlete training. Acclimatization to low oxygen (pre-conditioning) confers cross protection to other physical, environmental and pharmacological stressors, and using animal models this phenomenon has been translated for use in the clinical setting, for example in ischemic preconditioning used immediately prior to brain and cardiac surgery. An alternative to altitude acclimatization is passive intermittent hypoxia exposure (IHE), a laboratory-based technique developed to simulate the effects of altitude acclimatization. In healthy individuals IHE has been reported to stimulate adaptations produced in the body in response to altitude. These adaptations include increases in hypoxia inducible factor, erythropoietin, red blood cell count, hematocrit, haemoglobin concentration and reticulocyte production. Such increases offer a protective role by enhancing oxygen delivery to the tissues and by increasing cellular protection and tolerance to further hypoxic insults.
Particles, string and interface in the three-dimensional Ising model

description: We consider the three-dimensional Ising model slightly below its critical temperature, with boundary conditions leading to the presence of an interface. We show how the interfacial properties can be deduced starting from the particle modes of the underlying field theory. The product of the surface tension and the correlation length yields the particle density along the string whose propagation spans the interface. We also determine the order parameter and energy density profiles across the interface, and show that they are in complete agreement with Monte Carlo simulations that we perform.
