Subjects: subject: Astrophysics (astro-ph)

description: Long gamma-ray bursts (GRBs) from rapidly spinning black hole-torus systems may represent hypernovae or black hole-neutron star coalescence. We show that the torus may radiate gravitational radiation powered by the spin-energy of the black hole in the presence of non-axisymmetries. The coupling to the spin-energy of the black hole is due to equivalence in poloidal topology to pulsar magnetospheres. Results calculated in the suspended accretion state indicate that GRBs are potentially the most powerful LIGO/VIRGO burst-sources in the Universe, with an expected duration of 10-15s on a horizontal branch of 1-2kHz in the $\dot{f}(f)-$diagram.

Kinda Human: Enhancing Expression and Understanding in an Intimate Relationship Through Artificial Agents
Creators: name: Dombkowski, Scott
Publisher: name: Carnegie Mellon University
Year: 2019
Subjects: Design

description: Today, many designers concern themselves with efficiency, effectiveness, and productivity when considering relationships between humans and artificial agents. While these three dimensions are essential to consider, they fail to embrace our humanity (i.e., our ability for self-expression and for understanding others) and present an opportunity for designers to consider dimensions present in our relationships that make us human. This thesis project explores two of those dimensions—expression and understanding—in the context of intimate relationships.
In this thesis, I:
• Investigated the theory, potential applications, and affordances of intimate relationships (which tend to be a person’s most defining and determining), artificial agents, and other relevant research areas.
• Acquired a comprehensive understanding of the models users have of artificial agents and intimate relationships by conducting several design studies.
• Created and evaluated several artificial agents designed to enhance intimate partners’ capacity for expression and understanding.
• Developed a set of principles and challenges to assist those designing for expression and understanding in intimate relationships.
Ultimately, this thesis serves as a lodestar that is intended to guide designers through the inherent complexities of designing interfaces that leverage artificial agents to aid expression and understanding by the user. I aim for my research and exploration to apply to areas that extend beyond a focus on expression and understanding, and serve as a guide for anyone who is interested in learning how designers might address dimensions that cannot be easily measured.

Local and nonlocal magnetic diffusion and alpha-effect tensors in shear flow turbulence

Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Various approaches to estimate turbulent transport coefficients from numerical simulations of hydromagnetic turbulence are discussed. A quantitative comparison between the averaged magnetic field obtained from a specific three-dimensional simulation of a rotating turbulent shear flow in a slab and a simple one-dimensional alpha-omega dynamo model is given. A direct determination of transport coefficients is attempted by calculating the correlation matrix of different components of the field and its derivatives. The alpha-effect operating on the toroidal field is found to be negative and of similar magnitude as the value obtained previously by correlating the electromotive force with the mean magnetic field. The turbulent diffusion of the toroidal field is comparable to the kinematic viscosity that was determined earlier by comparing the stress with the shear. However, the turbulent diffusion of the radial field component is smaller and can even be formally negative. The method is then modified to obtain the spectral dependence of the turbulent transport coefficients on the wavenumber. There is evidence for nonlocal behavior in that most of the response comes from the smallest wavenumbers corresponding to the largest scale possible in the simulation.

Subjects: subject: meme marketing

subject: advertising communication strategies

description: With consumer attention competition at an all-time high, marketing professionals are confronted with a daunting challenge: how to evolve marketing and advertising communication strategies in today's information-rich world to cut through the noise? (Nelson-Field, 2020). Meme marketing in this regard taps into the potential of digital participatory culture and attention economy, allowing brands to communicate with customers in a naturalistic way (Malodia, Dhir, Bilgihan, Sinha, & Tikoo, 2022). Internet memes have transformed into a prominent social media linguistic discourse. Brands can effectively engage consumers, increase brand visibility, and foster meaningful connections by leveraging meme marketing. However, despite considerable practitioner interest, academic meme marketing research is lagging, resulting in an important knowledge gap (Sharma, 2018; Wu & Ardley, 2007). To address this gap comprehensively, this study first meticulously defines meme marketing, drawing from speech act theory (SAT) and the theory of consumption values (TCV), paving the way for a robust framework. Following this, the study investigates the effectiveness of meme marketing, unravelling the underlying mechanisms through narrative transportation theory and identifying crucial boundary conditions. This holistic approach addresses not only the definitional gaps but also enhances our understanding of meme marketing's impact on consumer attitudes and engagement. Accordingly, this study addresses two main research questions: (RQ1), "What are the underlying communicative intentions of meme marketing, and how can they be categorised and validated through a taxonomy of meme marketing speech acts, contributing to the conceptualisation and definition of meme marketing?" and (RQ2), "What is the mediating role of narrative transportation in the relationship between meme marketing and consumer attitudes and engagement? Further, what is the moderating role of brand knowledge and meme literacy in the relationship between meme marketing and consumer attitudes and engagement?" The first research question is examined in Study 1, while the second research question is addressed in Studies 2(a) and (b), respectively. [...]
GRB010222: afterglow emission from a rapidly decelerating shock

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The GRB010222 optical and near-infrared (NIR) afterglow was monitored at the TNG and other Italian telescopes starting ~1 day after the high-energy prompt event. The optical BVR light curves, which are the best sampled, are continuously steepening, and can be described by two power laws, f(t) = t^(-alpha), of indices alpha_1 ~ 0.7 and alpha_2 ~ 1.3 before and after a break occurring at about 0.5 days after the GRB start time, respectively. This model accounts well also for the flux in the U, I and J bands, which are less well monitored. The temporal break appears to be achromatic. The two K-band points are not consistent with the above behaviour, and rather suggest a constant trend. A low-resolution optical spectrum has also been taken with TNG. In the optical spectrum we found three absorption systems at different redshifts (0.927, 1.155 and 1.475), the highest of which represents a lower limit to, and probably coincides with, the redshift of this GRB. The broad-band optical spectral energy distributions do not appear to vary with time, consistently with the achromatic behaviour of the light curves. We compare our measurements with different afterglow evolution scenarios and we find that they favor a transition from relativistic to non-relativistic conditions in the shock propagation.

description: Natural products (NPs) continue to have significant impact in the area of drug discovery and development. More than 50% of the approved drugs between 1981 and 2014 were either unaltered NPs, NP derivatives or synthetic drugs inspired by NP pharmacophores. NPs have also served as lead molecules in drug development programs; noteworthy example include the semi-synthetic antifungal drugs caspofungin, anidulafungin, and micafungin that were based on NP lead compounds isolated from the fermentation products of various fungus. Other notable examples include the sponge metabolite halichondrin B that was developed into the anticancer drug eribulin, and camptothecin, a plant NP that was developed into the oncology drugs, topotecan and irinotecan. Many research groups are now utilizing isolated NPs as scaffolds for the generation of semi-synthetic analogue libraries rather than pursuing the total synthesis of a bioactive NP followed by classic medicinal chemistry. This approaches main advantage is the reduction in timelines and resource allocation, which is typically associated with de novo multi-step syntheses of a bioactive NP. Furthermore, once the NP scaffold has been isolated from the source biota rapid analogue generation and subsequent SAR data can be acquired. Thus the evaluation of a scaffold chemotype for potential lead optimization studies is quickly assessed.

description: Spatial topology endows topological solitons, such as skyrmions and hopfions, with fascinating dynamics. However, the temporal dimension has so far provided a passive stage on which topological solitons evolve. Here we construct spacetime magnetic hopfions: magnetic textures in two spatial dimensions that when excited by a time-periodic drive develop spacetime topology. We uncover two complementary construction routes using skyrmions by braiding their center of mass position and by controlling their internal low-energy excitations. Spacetime magnetic hopfions can be realized in nanopatterned grids to braid skyrmions and in frustrated magnets under an applied AC electric field. Their topological invariant, the spacetime Hopf index, can be tuned by the applied electric field as demonstrated by our collective coordinate modeling and micromagnetic simulations. The principles we have introduced to actively control spacetime topology are not limited to magnetic solitons, opening avenues to explore spacetime topology of general order parameters and fields.

In doing so, we prove stronger versions for basing -- rather than locally basing or EM-basing -- str-trees on s-trees and str$_0$-trees on str-trees. As an application we show that a thick positive theory has $k$-TP$_2$ iff it has $2$-TP$_2$.

description: This thesis describes research investigating the effectiveness of an online learning environment in a Saudi tertiary setting. A review of the literature examined the rationale and benefits of online learning and critical issues contributing to the effectiveness and quality of online learning environments, pertaining to learning theories and pedagogies associated with online learning, online instructional design, online communication, online instructor and online students. The examination of students’ and instructors’ experiences and perceptions of online teaching and learning assisted in gaining insights into the overall effectiveness of an online learning model, identifying the pedagogies and instructional design currently associated with online delivery, and determining a number of critical components that would construct an effective online learning environment in Saudi tertiary settings. Students’ experiences and perceptions of their online learning were discovered through quantitative and qualitative methods. The quantitative data on students’ experiences were gathered by using an adapted version of the Web-based Learning Environment Instrument (WEBLEI). The qualitative data on students’ experiences were collected by open-ended discussion questions attached to the WEBLEI survey. Instructors’ perceptions and experiences of their online teaching were investigated through a quantitative survey using written open-ended discussion questions. The study synthesised results from both qualitative and quantitative data and gives insight into constructing an effective online learning environment within Saudi tertiary sectors.

description: Magnetic skyrmions in thin films with perpendicular magnetic anisotropy are promising candidates for magnetic memory and logic devices, making the development of ways to transport skyrmions efficiently and precisely of significant interest. Here, we investigate the transport of skyrmions by surface acoustic waves (SAWs) via several modalities using micromagnetic simulations. We show skyrmion pinning sites created by standing SAWs at anti-nodes and skyrmion Hall-like motion without pinning driven by travelling SAWs. We also show how orthogonal SAWs formed by combining a longitudinal travelling SAW and a transverse standing SAW can be used for the 2D positioning of skyrmions. Our results also suggest SAWs offer a viable approach to the transport of multiple skyrmions along multichannel racetrack.

Publisher: name: Griffith University

Subjects: subject: Gait variables
subject: Biomechanics during walking

description: The general purpose of this project was to gain further insight into the effect of ageing on swing phase biomechanics during walking. A particular emphasis was placed on the effect of ageing on the critical gait variables anterior-posterior heel contact velocity (A-P HCV) and minimum toe clearance (MTC). In addition, techniques were developed to i) obtain three-dimensional (3D) joint kinematics from an electromagnetic tracking system (ETS) and ii) quantify a compensatory synergy in a multiple degree-of-freedom (DOF) precision task, namely gait. Intra-trial, intra-day/inter-tester and inter-day/intratester repeatability of gait kinematics acquired using the ETS-based technique was equivalent or superior to that obtained using optoelectronic and video based systems. Compared with young participants, the elderly exhibited a greater A-P HCV and greater MTC variability. The postural configuration of the elderly at the time of MTC (timeMTC) was different to that of the young, while no marked differences in joint angle variability at timeMTC were identified. Both the young and elderly were found to exhibit compensatory synergies between kinematic DOFs that acted to minimise MTC variability. The overall strength of these synergies was similar for the young and elderly however the number of DOFs involved in the synergy was less for the elderly than the young. In conclusion, healthy elderly individuals exhibit changes in their walking pattern that may place them a greater risk of a slip and or trip-related fall than their younger counterparts.

 Taxonomy. The above generic synonymy of Phyllobioides with Urometopus implies the new combination of Urometopus rugifrons (Hochhuth, 1851). As for the above discussed synonymy of U. rugifrons with U. strigifrons, according to an unpublished note by Yunakov they represent two different species (R. Borovec, pers. comm.), and only the latter occurs in Russia (YUNAKOV 2011). Thus Urometopus rugifrons (Hochhuth, 1851), stat. restit., is here revived from synonymy with U. strigifrons (Gyllenhal, 1934).

title: Investigating the dynamics of skin immune response in arbovirus infection
Creators: name: Tharmarajah, Kothila
Publisher: name: Griffith University
Year: 2022
Subjects: subject: arbovirus infection
subject: skin infection
subject: immune response

description: The skin is the first line of defence against most infections, including those by arthropod-borne viruses (arboviruses) such as Ross River virus (RRV) and Chikungunya virus (CHIKV). RRV and CHIKV are arthritogenic arboviruses that cause debilitating musculoskeletal and arthritic disease. They are considered significant public health threats of major global concern due to the scale of outbreaks, and the limited treatment options available. The skin is a compartmentalised organ and is populated by an abundance of immune and non-immune cells which have been proven targets of mosquito-borne viruses. To understand the dynamics of arthritogenic arbovirus dissemination following skin infection, we developed a pathogenic model of RRV infection to mimic a mosquito bite. We demonstrated that inoculation of RRV intradermally into the skin of mice disseminates systemically to causes musculoskeletal pathogenesis similar to that observed for the current subcutaneous RRV infection model. Further, we provide evidence suggesting RRV disseminates from the site of infection in the skin to lymphoid organs via lymphatic drainage at earlier stages of infection (prior to 24hpi). Consistent with cutaneous arboviral infection studies, we found inflammatory monocytes, neutrophils and dermal macrophages dominated the early inflammatory response in the skin. Importantly, we unveiled a critical role for cellular source of the virus in driving viral dissemination kinetics and disease severity. Intradermal infection with RRV derived from mosquito cells resulted in more severe disease compared to RRV derived from mammalian cells. This difference in disease was accompanied by specific transcriptional responses to mammalian cell-derived RRV and mosquito cell-derived RRV in the skin and skin draining LN after intradermal infection. Interestingly we show evidence indicating that cellular source of the virus dictates the dissemination of RRV to target tissues in muscle and joint. Finally, we used our intradermal infection model to elucidate a role for RRV envelope glycosylation in determining the differences in disease severity between mosquito cell and mammalian cell-derived RRV. Using glycan mass spectrometry and Nanostring differential gene expression analysis, we show that the high mannose N-linked glycans on RRV derived from mosquito cell aid virus to evade immune detection to replicate efficiently and establish increased dissemination of RRV leading to a more severe disease. Using a physiologically relevant model of cutaneous arboviral infection, we show previously unappreciated mechanisms of immune response and viral dissemination that, in future, will help develop novel approaches to limit arboviral dissemination and ameliorate disease outcomes.
Holographic RG from ERG: Locality and General Coordinate Invariance in the Bulk

description: In earlier papers it was shown that the correct kinetic term for scalar, vector gauge field and the spin two field in $AdS_{D+1}$ space is obtained starting from the ERG equation for a $CFT_D$ perturbed by scalar composite, conserved vector current and conserved traceless energy momentum tensor respectively. In this paper interactions are studied and it is shown that a flipped version of Polchinski ERG equation that evolves towards the UV can be written down and is useful for making contact with the usual AdS/CFT prescriptions for correlation function calculations. The scalar-scalar-spin-2 interaction in the bulk is derived from the ERG equation in the large $N$ semiclasical approximation.
 It is also shown that after mapping to AdS the interaction is local on a scale of the bare cutoff rather than the moving cutoff (which would have corresponded to the AdS scale). The map to $AdS_{D+1}$ plays a crucial role in this locality. The local nature of the coupling ensures that this interaction term in the bulk action is obtained by gauge fixing a general coordinate invariant scalar kinetic term in the bulk action. A wave function renormalization of the scalar field is found to be required for a mutually consistent map of the two fields to $AdS_{D+1}$.

The effect deforms primordial scalar power spectrum causing asymmetry in it, which leaves imprint on CMB anisotropies and the cosmic structure. Parameter space of this combined model allows for enhancement of logarithmic scale dependence of this deformation, as opposed to simpler models in which such scale dependence is suppressed by slow-roll parameters.

description: In ordinary turbulence research it has been a long standing tradition to solve the equations in spectral space giving the best possible accuracy. This is indeed a natural choice for incompressible problems with periodic boundaries, but it is no longer optimal in many astrophysical circumstances. It is argued that lower order spatial derivatives schemes are unacceptable in view of their low overall accuracy, even when mass, momentum, and energy are conserved to machine accuracy. High order finite difference schemes are therefore found to be quite efficient and physically appropriate. They are also easily and efficiently implemented on massively parallel computers. High order schemes also yield sufficient overall accuracy. Our code uses centered finite differences which make the adaptation to other problems simple. Since the code is not written in conservative form, conservation of mass, energy and momentum can be used to monitor to quality of the solution. A third order Runge-Kutta scheme with 2N-storage is used for calculating the time advance.

description: In the realm of data classification, broad learning system (BLS) has proven to be a potent tool that utilizes a layer-by-layer feed-forward neural network. However, the traditional BLS treats all samples as equally significant, which makes it less robust and less effective for real-world datasets with noises and outliers. To address this issue, we propose fuzzy broad learning system (F-BLS) and the intuitionistic fuzzy broad learning system (IF-BLS) models that confront challenges posed by the noise and outliers present in the dataset and enhance overall robustness. Employing a fuzzy membership technique, the proposed F-BLS model embeds sample neighborhood information based on the proximity of each class center within the inherent feature space of the BLS framework. Furthermore, the proposed IF-BLS model introduces intuitionistic fuzzy concepts encompassing membership, non-membership, and score value functions. IF-BLS strategically considers homogeneity and heterogeneity in sample neighborhoods in the kernel space. We evaluate the performance of proposed F-BLS and IF-BLS models on UCI benchmark datasets with and without Gaussian noise. As an application, we implement the proposed F-BLS and IF-BLS models to diagnose Alzheimer's disease (AD). Experimental findings and statistical analyses consistently highlight the superior generalization capabilities of the proposed F-BLS and IF-BLS models over baseline models across all scenarios. The proposed models offer a promising solution to enhance the BLS framework's ability to handle noise and outliers. The source code link of the proposed model is available at https://github.com/mtanveer1/IF-BLS.

description: The most interesting current open question in the theory of GRB afterglow is the propagation of jetted afterglows during the sideway expansion phase. Recent numerical simulations show hydrodynamic behavior that differs from the one suggested by simple analytic models. Still, somewhat surprisingly, the calculated light curves show a `jet break' at about the expected time. These results suggest that the expected rate of orphan optical afterglows should be smaller than previously estimated.

description: We investigate the quasiparticle dynamics in the prototype heavy fermion CeCoIn$_5$ using ultrafast optical pump-probe spectroscopy. Our results indicate that this material system undergoes hybridization fluctuations before full establishment of the heavy electron coherence, as the temperature decreases from $\sim$120 K ($T^\dagger$) to $\sim$55 K ($T^*$ ). We reveal that the observed anomalous phonon softening and damping reduction below $T^*$ are directly associated with opening of an indirect hybridization gap. We also discover a distinct collective mode with an energy of $\sim$8 meV, which may be the experimental evidence of the predicted unconventional density wave. Our observations provide critical informations for understanding the hybridization dynamics in heavy fermion materials.

description: Abstract
Cancer treatment is costly and can be just as harmful as helpful to the patient. As a result, patients often
seek alternative treatment options, such as herbal therapy including the use of essential oils. Common
essential oils include cinnamon, clove, eucalyptus, lemon, and rosemary; combined, these oils comprise
Thieves. To determine if Thieves and the individual oils influence cancer cell viability, MCF-7 and
MDA-MB-231 breast cancer cells were exposed to 0.001% to 1.0% oils and their major chemical
components for forty-eight hours, followed by determination of toxicity using an MTT cell viability
assay. Although all oils led to some cell death, MCF-7 cells were more susceptible to oil treatment than
MDA-MB-231 cells. Of the Thieves components, clove and cinnamon were the most toxic, followed by
lemon, eucalyptus, and rosemary. These toxicities are most likely due to the major chemical components
of the oils, including eugenol, limonene, and cineole.

description: Organic food is claimed to be one of the fastest growing food categories worldwide, with annual sale growth rates of 20-30%. While the uptake of organic foods is higher in G7 countries, organic consumption rates in Australia are significantly lower than other comparable Western markets, despite general positive attitudes towards organics, and significant organic production areas. Impediments to organic food uptake have been identified previously from both a supply- and demand-side perspective. Impediments include availability, pricing and certification. The aims of this research are twofold. First, this research seeks to understand what Australian consumers currently understand about organic certification schemes and labelling. Second, it incorporates a large-scale national survey that examines preferences for organic alternatives. This research applies a choice-based method, best-worst (BW) scaling, in three organic food categories to understand the trade-offs that respondents are willing to make.
Two-dimensional hole transport in ion-gated diamond surfaces: A brief review

description: Electrically-conducting diamond is a promising candidate for next-generation electronic, thermal and electrochemical applications. One of the major obstacles towards its exploitation is the strong degradation that some of its key physical properties - such as the carrier mobility and the superconducting transition temperature - undergo upon the introduction of disorder. This makes the two-dimensional hole gas induced at its surface by electric field-effect doping particularly interesting from both a fundamental and an applied perspective, since it strongly reduces the amount of extrinsic disorder with respect to the standard boron substitution. In this short review, we summarize the main results achieved so far in controlling the electric transport properties of different field-effect doped diamond surfaces via the ionic gating technique. We analyze how ionic gating can tune their conductivity, carrier density and mobility, and drive the different surfaces across the insulator-to-metal transition. We review their strongly orientation-dependent magnetotransport properties, with a particular focus on the gate-tunable spin-orbit coupling shown by the (100) surface. Finally, we discuss the possibility of field-induced superconductivity in the (110) and (111) surfaces as predicted by density functional theory calculations.

description: Far-infrared spectra of laboratory silicates are normally obtained at room temperature even though the grains responsible for astronomical silicate emission bands seen at wavelengths >20 micron are likely to be at temperatures below ~150 K. In order to investigate the effect of temperature on silicate spectra, we have obtained absorption spectra of powdered forsterite and olivine, along with two orthoenstatites and diopside clinopyroxene, at 3.5+-0.5 K and at room temperature (295+-2K). To determine the changes in the spectra the resolution must be increased from 1 to 0.25 cm^-1 at both temperatures since a reduction in temperature reduces the phonon density, thereby reducing the width of the infrared peaks. Several bands observed at 295 K split at 3.5 K. At 3.5 K the widths of isolated single bands in olivine, enstatites and diopside are ~ 90% of their 295 K-widths. However, in forsterite the 3.5-K-widths of the 31-, 49- and 69-micron bands are, respectively, 90%, 45% and 31% of their 295 K widths. Due to an increase in phonon energy as the lattice contracts, 3.5-K-singlet peaks occur at shorter wavelengths than do the corresponding 295-K peaks; the magnitude of the wavelength shift increases from \~ 0-0.2 micron at 25 micron to ~0.9 micron at 80 micron. Changes in the relative absorbances of spectral peaks are also observed. The temperature dependence of lambda_pk and bandwidth shows promise as a means to deduce characteristic temperatures of mineralogically distinct grain populations. In addition, the observed changes in band strength with temperature will affect estimates of grain masses and relative mineral abundances inferred using room-temperature laboratory data.

description: Van der Waals (vdW) magnetic materials such as Cr2Ge2Te6 (CGT) show promise for novel memory and logic applications. This is due to their broadly tunable magnetic properties and the presence of topological magnetic features such as skyrmionic bubbles. A systematic study of thickness and oxidation effects on magnetic domain structures is important for designing devices and vdW heterostructures for practical applications. Here, we investigate thickness effects on magnetic properties, magnetic domains, and bubbles in oxidation-controlled CGT crystals. We find that CGT exposed to ambient conditions for 5 days forms an oxide layer approximately 5 nm thick. This oxidation leads to a significant increase in the oxidation state of the Cr ions, indicating a change in local magnetic properties. This is supported by real space magnetic texture imaging through Lorentz transmission electron microscopy. By comparing the thickness dependent saturation field of oxidized and pristine crystals, we find that oxidation leads to a non-magnetic surface layer which is thicker than the oxide layer alone. We also find that the stripe domain width and skyrmionic bubble size are strongly affected by the crystal thickness in pristine crystals. These findings underscore the impact of thickness and surface oxidation on the properties of CGT such as saturation field and domain/skyrmionic bubble size and suggest a pathway for manipulating magnetic properties through a controlled oxidation process.

description: Dark matter subhalos, predicted in large numbers in the cold dark matter scenario, should have an impact on particle dark matter searches. Recent results show that tidal disruption of these objects in computer simulations is over-efficient due to numerical artifacts and resolution effects. Accounting for these results, we re-estimate the subhalo abundance in the Milky Way using semi-analytical techniques. In particular, we show that the boost factor for gamma rays and cosmic-ray antiprotons is increased by roughly a factor of two.
