description: Background: With the increasing digitalization of the health sector, more and more mobile health (mHealth) apps are coming to the market to continuously collect and process sensitive health data for the benefit of patients and providers. These technologies open up new opportunities to make the health care system more efficient and save costs but also pose potential threats such as loss of data or finances. Objective: This study aims to present an empirical review and adaptation of the extended privacy calculus model to the mHealth domain and to understand what factors influence the intended usage of mHealth technologies. Methods: A survey study was conducted to empirically validate our model, using a case vignette as cover story. Data were collected from 250 German participants and analyzed using a covariance-based structural equation model. Results: The model explains R2=79.3% of the variance in intention to use. The 3 main factors (social norms, attitude to privacy, and perceived control over personal data) influenced the intention to use mHealth apps, albeit partially indirectly. The intention to use mHealth apps is driven by the perceived benefits of the technology, trust in the provider, and social norms. Privacy concerns have no bearing on the intention to use. The attitude to privacy has a large inhibiting effect on perceived benefits, as well as on trust in the provider. Perceived control over personal data clearly dispels privacy concerns and supports the relationship of trust between the user and the provider. Conclusions: Based on the privacy calculus, our domain-specific model explains the intention to use mHealth apps better than previous, more general models. The findings allow health care providers to improve their products and to increase usage by targeting specific user groups.
The X-Ray to Mid-Infrared Relation of AGN at High Luminosity

description: The X-ray and mid-IR emission from active galactic nuclei (AGN) are strongly correlated. However, while various published parameterizations of this correlation are consistent with the low-redshift, local Seyfert galaxy population, extrapolations of these relations to high luminosity differ by an order of magnitude at nuL(nu)(6um) = 1e47 erg/s. Using data from the Wide-field Infrared Survey Explorer, we determine the mid-IR luminosities of the most luminous quasars from the Sloan Digital Sky Survey and present a revised formulation of the X-ray to mid-IR relation of AGN which is appropriate from the Seyfert regime to the powerful quasar regime.

description: We study the photon statistics properties of few-photon transport in an optomechanical system where an optomechanical cavity couples to two empty cavities. By analytically deriving the one- and two-photon currents in terms of a zero-time-delayed two-order correlation function, we show that a photon blockade can be achieved in both the single-photon strong-coupling regime and the single-photon weak-coupling regime due to the nonlinear interacting and multipath interference. Furthermore, our systems can be applied as a quantum optical diode, a single-photon source, and a quantum optical capacitor. It is shown that this the photon transport controlling devices based on photon antibunching does not require the stringent single-photon strong-coupling condition. Our results provide a promising platform for the coherent manipulation of optomechanics, which has potential applications for quantum information processing and quantum circuit realization.
title: Pulsed Laser-Assisted Photocatalytic Metal Deposition for SERS Applications
titleType: Other
Creators: name: Hoffman, Manuel
Publisher: name: University of Dundee
Year: 2023

description: Surface-enhanced Raman spectroscopy (SERS) is a vibrational spectroscopy technique to extend the inherent specificity of Raman spectroscopy by sensitivities down to the single molecule level. The ultra-high sensitivities observed in SERS are reliant on the plasmonic properties of silver (Ag) and gold (Au) nanoparticles. Plasmons, the oscillation of the metal particle electron cloud, give rise to the electric fields responsible for SERS enhancement. Plasmonic properties depend crucially on features of the metallic nanostructure. Optimal plasmonic response for SERS applications is achieved on tailored nanostructures with Ag and Au nanoparticle sizes ranging from 10 to 100 nm at the lowest possible particle edge distances. SERS benefits further from the unique properties of semiconductor/metal composites. A promising methodology to produce such nanostructured composites is photocatalytic metal deposition on semiconductors. Herein, optimisation of the pulsed laser-assisted photocatalytic deposition process for SERS applications is demonstrated. The utilised semiconductor, a transparent titanium dioxide thin film, was tailored for the laser-assisted process to capitalise on laser writing and direct laser interference patterning (DLIP) capabilities. Effects of key process parameters on Ag and Au nanostructure were systematically investigated by Design of Experiment. Several significant parameter effects were identified, including the effect of nanosecond compared to picosecond pulse lengths. The Au deposition process showed distinct differences from the Ag deposition. Informed by Design of Experiment, optimised Ag and Au nanostructures on semiconductor thin film for use as SERS substrates were prepared. SERS performance was studied at excitation wavelengths of 532, 633 and 785 nm using Thiophenol as the probe molecule. Utilising the laser writing approach, broadband SERS performance with enhancement factors (EF) of 10^5 to 10^6 was achieved for both metals. Utilising the DLIP approach multiscale patterned nanostructures at sub-micron periods were fabricated. Diffractive far-field coupling as well as the coupled plasmonic modes in periodic resonator chains increased SERS EFs of Ag and Au nanostructures further, to 10^6 to 10^7.

description: Doctors are increasingly expected to demonstrate medical leadership and management (MLM) skills. The Faculty of Medical Leadership and Management (FMLM) has published an indicative undergraduate curriculum to guide the development of MLM content at UK medical schools. Students from 30 medical schools were surveyed to determine their understanding of MLM teaching at their school. Timetables for 21 schools were searched for MLM-related keywords. Student-reported teaching and timetabled teaching were coded according to predefined themes. Aggregated demographic and postgraduate performance data were obtained through collaboration with the Medical Student Investigators Collaborative (msico.org). Whilst 88% of medical students see MLM teaching as relevant, only 18% believe it is well integrated into their curriculum. MLM content represented ∼2% of timetabled teaching in each 5-year undergraduate medical course. Most of this teaching was dedicated to teamwork, performance/reflection and communication skills. There was minimal association between how much of a topic students believed they were taught, and how much they were actually taught. We found no association between the volume of MLM teaching and performance in postgraduate examinations, trainee career destinations or fitness to practice referrals. Our findings demonstrate limited and variable teaching of MLM content. Delivery was independent of broader teaching and assessment factors.

description: H2O is one of the most important substances needed in sustaining life; but yet not much is known about its ground state. Here, a previously unidentified anomaly is identified in the form of a minimum in the imaginary part of the dielectric constant with respect to temperature near 20 K while the real part remains monotonic. Isothermal dispersion and absorption measurements show coinciding results. For the case of heavy ice (D2O), no anomaly was identified confirming an apparent isotope effect. Concerted quantum tunneling of protons is believed to be the main cause behind the reported anomaly. Our findings identify another system that exhibits macroscopic quantum phenomena of which rarely occur in nature.

description: We sought to design a micro-curriculum to structure supervised clinical placements for junior medical students within a variety of community-based settings of differing clinical disciplines. Given the gaps in the literature, this paper reflects on the opportunities and challenges of our design, implementation, and evaluation strategies in constructing an integrated task-based micro-curriculum for interprofessional community-based learning in year 2 of a four-year graduate entry program. The design was informed by a systems thinking framework and guided by contemporary curricular theories on self-directed and interprofessional learning. Extensive consultations with stakeholders were undertaken. Alignment with relevant national level documents and curricular frameworks was ensured. The systems thinking approach provided first, an experience of applying thinking tools for a deeper understanding of how various parts of this micro-curriculum and subsystems should be integrated. Second, applying the toolkit uncovered tension points on which leverage could optimise future enhancements. Eighteen types of health professions were recruited including 105 general practitioners and 253 healthcare practitioners from a range of disciplines. Systems thinking allows for the identification of various interacting elements within the curriculum to be considered as part of an integrated whole. Insights from this model could inform the design of similar innovative curricula.

description: Quantum interference (QI) effects in molecular junctions may be used to obtain large thermoelectric responses. We study the electrical conductance G and the thermoelec- tric response of a series of molecules featuring a quinoid core using density functional theory (DFT), as well as a semi-empirical interacting model Hamiltonian describing the π-system of the molecule which we treat in the GW approximation. Molecules with a quinoid type structure are shown to have two distinct destructive QI features close to the frontier orbital energies. These manifest themselves as two dips in the transmission, that remain separated, even when either electron donating or withdraw- ing side groups are added. We find that the position of the dips in the transmission and the frontier molecular levels can be chemically controlled by varying the electron donating or withdrawing character of the side groups as well as the conjugation length inside the molecule. This feature results in a very high thermoelectric power factor S^2G and figure of merit ZT, where S is the Seebeck coefficient, making quinoid type molecules potential candidates for efficient thermoelectric devices.

Eikonal approximation, Finsler structures, and implications for Lorentz-violating photons in weak gravitational fields

Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The current article shall contribute to understanding the classical analogue of the minimal photon sector in the Lorentz-violating Standard-Model Extension (SME). It is supposed to complement all studies performed on classical point-particle equivalents of SME fermions. The classical analogue of a photon is not a massive particle being described by a usual equation of motion, but a geometric ray underlying the eikonal equation. The first part of the paper will set up the necessary tools to understand this correspondence for interesting cases of the minimal SME photon sector. In conventional optics the eikonal equation follows from an action principle, which is demonstrated to work in most (but not all) Lorentz-violating cases as well. The integrands of the action functional correspond to Finsler structures, which establishes the connection to Finsler geometry. The second part of the article treats Lorentz-violating light rays in a weak gravitational background by implementing the principle of minimal coupling. Thereby it is shown how Lorentz violation in the photon sector can be constrained by measurements of light bending at massive bodies such as the Sun. The phenomenological studies are based on the currently running ESA mission GAIA and the planned NASA/ESA mission LATOR. The final part of the paper discusses certain aspects of explicit Lorentz violation in gravity based on the setting of Finsler geometry.

description: Background: Systematic reviews are a popular publication type for researchers and are increasingly used as experiential learning tools in curricula.  Systematic review software helps to expedite reviews by organizing and streamlining parts of the review process and reducing data entry.  Despite the many benefits of this software, libraries may not be able to support the purchase of systematic review tools that can cost anywhere from the price of a journal to the price of an entire database.  This study analyzes the usability of free systematic review software for use by individual reviewers or review teams and in classroom settings. Methods: Using the Systematic Review Toolbox to identify systematic review software, librarians tested several types of systematic review software by performing sample reviews.  They performed a structured analysis of the software, looking at dimensions such as learning curve, data import/export, range of functions available, ease of screening, sorting capabilities, managing full text, collaboration, and scalability. Results: Results will be presented as a poster at MAC 2017. Conclusion: Though there are many types of free systematic review software available, several have design flaws that would preclude them from certain types of use or user. This poster will compare the systematic review tools and features available in each type of software for various types of users.

description: Context. Mass loss is an important property in evolution models of massive stars. As up to 90% of the massive stars have a visual or spectroscopic companion and many of them exhibit mass exchange, mass-loss rates can be acquired through the period study of massive binaries. Aims. Using our own photometric observations as well as archival data, we look for variations in orbital periods of seven massive eclipsing binary systems in the Cygnus OB2 association and estimate their mass-loss rates and stellar parameters. Methods. We use a Bayesian parameter estimation method to simultaneously fit the period and period change to all available data and a stellar modelling tool to model the binary parameters from photometric and radial-velocity data. Results. Four out of the seven selected binaries show non-zero period change values at two-sigma confidence level. We also report for the first time the eclipsing nature of a star MT059.

Engineering room-temperature quantum magnetic sensors with fibre-cavity diamond lasers
Creators: name: Raman Nair, Sarath
Publisher: name: Macquarie University
Year: 2023
Subjects: Other education not elsewhere classified

description: This thesis studies the engineering of quantum magnetic sensors based on diamond lasers containing NV- colour centres. Specifically, the thesis experimentally and theoretically investigates two different scenarios for realizing diamond lasers in mechanically tunable fibre-based Fabry-Perot cavities. In the first scenario, we experimentally explore a diamond-loaded open tunable fibercavity system as a contender for realizing lasing with the negatively charged nitrogen-vacancy (NV-) centre in diamond as the gain medium. We measure the transmission characteristics of a cavity-resonant laser beam at a wavelength of 721 nm, close to the maximum of emission of the NV- phonon sideband, both with and without a green pump laser at 532 nm. For moderate green pump powers, we observe an amplification of the resonant red laser light and at the same time a reduction of the spontaneously emitted background photons. When increasing the pump power further, the amplification saturates and at the same time we see an increase in spontaneous photon emission. A qualitative model including stimulated emission and charge state switching of the NV- centre captures the dynamics in the experiment very well. The results allow conclusions to be drawn about the material challenges of realizing an NV- laser in diamond. In the second scenario, we theoretically study Raman lasing from a diamond crystal containing NV- centres. The intra-cavity absorption by the NV- centres modifies the Raman laser, and two interesting regimes are identified based on the position of the Raman and pump laser wavelengths with respect to the zero-phonon line (637nm) of the NV- centre. When both the pump and Raman wavelengths are below the zero-phonon line we identify a magnetically tunable bistability. When only the pump wavelength is below the zero-phonon line, we predict a shift in the laser threshold dependent on the NV- spin centres. Furthermore, we propose that such a system can be used as a technically demanding magnetic field sensor with a predicted DC sensitivity of the order of pT/ √flz.

description: In this paper, we extend our study of the holographic Rényi entropy of single interval on a torus to the CFT with W symmetry. To read the possible corrections from W fields clearly, we compute the thermal correction to the Rényi entropy up to the order $e^{-8π/TL}$. In the field theory, this requires us to compute the contribution from all the level 4 states, from both the vacuum module and W primaries. On the gravity side, after computing the eigenvalue of single Schottky generators to the order $e^{-4 π/TL}$, we obtain the 1-loop quantum correction to the holographic Rényi entropy. We find complete agreement between the bulk and boundary theories.

description: We study the diamagnetism induced by thermal fluctuations above the superconducting transition of the iron pnictide Ba(Fe$_{1-x}$Ni$_x$)$_2$As$_2$ with different doping levels. The measurements are performed with magnetic fields up to 7 T applied in the two main crystal directions. These data provide double information: first, they confirm at a quantitative level the applicability to these materials of a 3D-anisotropic Ginzburg-Landau approach valid in the finite field regime. Then, they allow to determine the doping-level dependence of the in-plane coherence length and of the superconducting anisotropy factor, $γ$. Our results provide a stringent confirmation of the large increase of $γ$ with the doping level, as recently proposed from magnetoresistivity measurements. The implications of the applicability of the model used to a multiband superconductor are discussed.

description: Previous observations of the Ap star HD 32633 indicated that its magnetic field was unusually complex in nature and could not be characterised by a simple dipolar structure. Here we derive magnetic field maps and chemical abundance distributions for this star using full Stokes vector (Stokes $IQUV$) high-resolution observations obtained with the ESPaDOnS and Narval spectropolarimeters. Our maps, produced using the Invers10 magnetic Doppler imaging (MDI) code, show that HD 32633 has a strong magnetic field which features two large regions of opposite polarity but deviates significantly from a pure dipole field. We use a spherical harmonic expansion to characterise the magnetic field and find that the harmonic energy is predominately in the $\ell=1$ and $\ell=2$ poloidal modes with a small toroidal component. At the same time, we demonstrate that the observed Stokes parameter profiles of HD 32633 cannot be fully described by either a dipolar or dipolar plus quadrupolar field geometry. We compare the magnetic field topology of HD 32633 with other early-type stars for which MDI analyses have been performed, supporting a trend of increasing field complexity with stellar mass. We then compare the magnetic field topology of HD 32633 with derived chemical abundance maps for the elements Mg, Si, Ti, Cr, Fe, Ni and Nd. We find that the iron-peak elements show similar distributions, but we are unable to find a clear correlation between the location of local chemical enhancements or depletions and the magnetic field structure.

description: Background: The Safe Drug Compounding Act of 2007 threatens to adversely affect many patients who rely on compounded medications to treat medical conditions for which no adequate commercially manufactured medication is available. Currently, no standard treatment for vulvodynia exists and many women rely on compounded medications to control the symptoms of this complex condition. In order to better understand the importance of compounding pharmacies in the provision of women’s health services and to identify trends in compounding for vulvodynia, we developed an online survey with the assistance of the University of North Carolina’s Odum Institute. The survey was distributed to compounding pharmacies across North Carolina. Our a priori hypothesis was that many areas of women’s health, specifically vulvo-vaginal disorders, rely heavily on compounding pharmacies and the services they provide. Objective: To establish the prevalence of medications compounded for women’s health issues across North Carolina. To identify trends in compounding for vulvodynia, with particular emphasis on the types and combinations of medications used.

description: PolyChord is a novel nested sampling algorithm tailored for high-dimensional parameter spaces. This paper coincides with the release of PolyChord v1.3, and provides an extensive account of the algorithm. PolyChord utilises slice sampling at each iteration to sample within the hard likelihood constraint of nested sampling. It can identify and evolve separate modes of a posterior semi-independently, and is parallelised using openMPI. It is capable of exploiting a hierarchy of parameter speeds such as those present in CosmoMC and CAMB, and is now in use in the CosmoChord and ModeChord codes. PolyChord is available for download at: http://ccpforge.cse.rl.ac.uk/gf/project/polychord/

description: It may well happen that the two main components of the dark sector of the Universe, dark matter and dark energy, do not evolve separately but interact nongravitationally with one another. However, given our current lack of knowledge on the microscopic nature of these two components there is no clear theoretical path to determine their interaction. Yet, over the years, phenomenological interaction terms have been proposed on mathematical simplicity and heuristic arguments. In this paper, based on the likely evolution of the ratio between the energy densities of these dark components, we lay down reasonable criteria to obtain phenomenological, useful, expressions of the said term independent of any gravity theory. We illustrate this with different proposals which seem compatible with the known evolution of the Universe at the background level. Likewise, we show that two possible degeneracies with noninteracting models are only apparent as they can be readily broken at the background level. Further, we analyze some interaction terms that appear in the literature.

Relationship between mass density, electron density, and elemental composition of body tissues for Monte Carlo simulation in radiation treatment planning

description: Purpose: For Monte Carlo simulation of radiotherapy, x-ray CT number of every system needs to be calibrated and converted to mass density and elemental composition. This study aims to formulate material properties of body tissues for practical two-step conversion from CT number. Methods: We used the latest compilation on body tissues that constitute reference adult male and female. We formulated the relations among mass, electron, and elemental densities into polylines to connect representative tissues, for which we took mass-weighted mean for the tissues in limited density regions. We compared the polyline functions of mass density with a bi-line for electron density and broken lines for elemental densities, which were derived from preceding studies. Results: There was generally high correlation between mass density and the other densities except of C, N, and O for light spongiosa tissues occupying 1% of body mass. The polylines fitted to the dominant tissues and were generally consistent with the bi-line and the broken lines. Conclusions: We have formulated the invariant relations between mass and electron densities and from mass to elemental densities for body tissues. The formulation enables Monte Carlo simulation in treatment planning practice without additional burden with CT-number calibration.

description: A computed line list for formaldehyde, H$_2{}^{12}$C$^{16}$O, applicable to temperatures up to $T=1500$~K is presented. An empirical potential energy and {\it ab initio} dipole moment surfaces are used as the input to nuclear motion program TROVE. The resulting line list, referred to as \textit{AYTY}, contains 10.3 million rotational-vibrational states and around 10 billion transition frequencies. Each transition includes associated Einstein-$A$ coefficients and absolute transition intensities, for wavenumbers below 10~000 cm\(^{-1}\) and rotational excitations up to \(J=70\). Room-temperature spectra are compared with laboratory measurements and data currently available in the HITRAN database. These spectra show excellent agreement with experimental spectra and highlight the gaps and limitations of the HITRAN data. The full line list is available from the CDS database as well as at \url{www.exomol.com}.

description: In the summer of 2011, a group of five librarians from the University of North Carolina at Chapel Hill (UNC-CH) Health Sciences and Kenan Science Libraries formed the Health and Natural Sciences (HNS) team to discuss library services and methods of service delivery to scientific researchers. The team’s charge was to determine what services subject librarians were currently providing to their respective constituencies, what services were most important to researchers, and how to develop individual specialties into a suite of standard services that could be offered to all scientists and clinicians across the university. The team tackled these questions with a multifaceted approach that led to the development of a new service model based on the research lifecycle.

description: Compressive sensing has been successfully used for optimized operations in wireless sensor networks. However, raw data collected by sensors may be neither originally sparse nor easily transformed into a sparse data representation. This paper addresses the problem of transforming source data collected by sensor nodes into a sparse representation with a few nonzero elements. Our contributions that address three major issues include: 1) an effective method that extracts population sparsity of the data, 2) a sparsity ratio guarantee scheme, and 3) a customized learning algorithm of the sparsifying dictionary. We introduce an unsupervised neural network to extract an intrinsic sparse coding of the data. The sparse codes are generated at the activation of the hidden layer using a sparsity nomination constraint and a shrinking mechanism. Our analysis using real data samples shows that the proposed method outperforms conventional sparsity-inducing methods.
