Managing integrated record systems : a conceptual foundation
Creators: name: Carney, Kathleen Laura
Publisher: name: University of British Columbia
Year: 2009

description: Organizational record systems have increased in complexity with the addition of another medium (electronic) to be managed. Moreover, the use of computer-based technology for making and keeping records engenders some confusion about the role of technology in determining the characteristics of record systems. Writings in the areas of organization theory, communication theory, archival science, diplomatics, and business management are analyzed in order to define and present the context, concepts and issues surrounding the creation, maintenance and administrative use of record systems. In light of this study, the thesis discusses the concepts of juridical system, organization, office information system, and the role of communication. It concludes that all these entities remain fundamentally unchanged by the use of modern technology. This thesis shows that while technology is a tool which helps human activity, it does not redefine the characteristics of the organization, its office system, the record system, or the records themselves. On the basis of this finding, the thesis suggests a conceptual approach and a set of definitions applicable to the practical management of integrated record systems in the organizational environment.

description: A multispectral image camera captures image data within specific wavelength ranges in narrow wavelength bands across the electromagnetic spectrum. Images from a multispectral camera can extract additional information that the human eye or a normal camera fails to capture and thus may have important applications in precision agriculture, forestry, medicine and object identification. Conventional multispectral cameras are made up of multiple image sensors each fitted with a narrow passband wavelength filter and optics, which makes them heavy, bulky, power hungry and very expensive. The multiple optics also create image co-registration problem. Here, we demonstrate a single sensor based three band multispectral camera using a narrow spectral band RGB colour mosaic in a Bayer pattern integrated on a monochrome CMOS sensor. The narrow band colour mosaic is made of a hybrid combination of plasmonic colour filters and heterostructured dielectric multilayer. The demonstrated camera technology has reduced cost, weight, size and power by almost n times (where n is the number of bands) compared to a conventional multispectral camera.

description: Previous studies show Republicans have lower risk perceptions of COVID-19 than Democrats. Has this gap in risk perception been consistent throughout the course of the pandemic? Using longitudinal data from the Understanding America Study’s Understanding Coronavirus in America longitudinal panel survey, we examine how time and vaccination status have changed Republican and Democratic risk perceptions of engaging in various activities (such as grocery shopping, visiting friends and family etc.) as well as risk perceptions of infection, hospitalization, and death due to COVID-19. We find that while Republicans have lowered their perceived risk of activity more than Democrats over time, vaccinated Democrats have lowered their perceived risk of infection, hospitalization, and death more than vaccinated Republicans. These results are robust to inclusion of media consumption and social media use. This divergence on the two measures of risk from COVID-19 may complicate leaders’ efforts to move on from the politics of the pandemic toward a return to “normal.”

description: Reservoir computing is a machine learning method that solves tasks using the response of a dynamical system to a certain input. As the training scheme only involves optimising the weights of the responses of the dynamical system, this method is particularly suited for hardware implementation. Furthermore, the inherent memory of dynamical systems which are suitable for use as reservoirs mean that this method has the potential to perform well on time series prediction tasks, as well as other tasks with time dependence. However, reservoir computing still requires extensive task-dependent parameter optimisation in order to achieve good performance. We demonstrate that by including a time-delayed version of the input for various time series prediction tasks, good performance can be achieved with an unoptimised reservoir. Furthermore, we show that by including the appropriate time-delayed input, one unaltered reservoir can perform well on six different time series prediction tasks at a very low computational expense. Our approach is of particular relevance to hardware implemented reservoirs, as one does not necessarily have access to pertinent optimisation parameters in physical systems but the inclusion of an additional input is generally possible.

description: We present resolved NACO photometry of the close binary AB Dor B in H- and Ks-band. AB Dor B is itself known to be a wide binary companion to AB Dor A, which in turn has a very low-mass close companion named AB Dor C. These four known components make up the young and dynamically interesting system AB Dor, which will likely become a benchmark system for calibrating theoretical pre-main sequence evolutionary mass tracks for low-mass stars. However, for this purpose the actual age has to be known, and this subject has been a matter of discussion in the recent scientific literature. We compare our resolved photometry of AB Dor Ba and Bb with theoretical and empirical isochrones in order to constrain the age of the system. This leads to an age estimate of about 50 to 100 Myr. We discuss the implications of such an age range for the case of AB Dor C, and compare with other results in the literature.

description: In the study of rock mechanics, the variation of rock mechanical characteristics in high-temperature environments is always a major issue. The discrete element method and Voronoi modeling method were used to study the mechanical characteristics and crack evolution of granite specimens subjected to the high temperature and uniaxial compression test in order to study the internal crack evolution process of granite under the influence of high temperatures. Meanwhile, dependable findings were acquired when compared to experimental outcomes. A modified failure criterion was devised, and a Fish function was built to examine the evolution behavior of tensile and shear cracks during uniaxial compression, in order to better understand the evolution process of micro-cracks in granite specimens. Shear contacts occurred first, and the number of shear cracks reached its maximum value earliest, according to the findings. The number of tensile contacts then rapidly grew, whereas the number of shear cracks steadily declined. Furthermore, it was found that when temperature rises, the number of early tensile cracks grows. This study develops a fracture prediction system for rock engineering in high-temperature conditions.
On the degree conjecture for separability of multipartite quantum states

description: We settle the so-called degree conjecture for the separability of multipartite quantum states, which are normalized graph Laplacians, first given by Braunstein {\it et al.} [Phys. Rev. A \textbf{73}, 012320 (2006)]. The conjecture states that a multipartite quantum state is separable if and only if the degree matrix of the graph associated with the state is equal to the degree matrix of the partial transpose of this graph. We call this statement to be the strong form of the conjecture. In its weak version, the conjecture requires only the necessity, that is, if the state is separable, the corresponding degree matrices match. We prove the strong form of the conjecture for {\it pure} multipartite quantum states, using the modified tensor product of graphs defined in [J. Phys. A: Math. Theor. \textbf{40}, 10251 (2007)], as both necessary and sufficient condition for separability. Based on this proof, we give a polynomial-time algorithm for completely factorizing any pure multipartite quantum state. By polynomial-time algorithm we mean that the execution time of this algorithm increases as a polynomial in $m,$ where $m$ is the number of parts of the quantum system. We give a counter-example to show that the conjecture fails, in general, even in its weak form, for multipartite mixed states. Finally, we prove this conjecture, in its weak form, for a class of multipartite mixed states, giving only a necessary condition for separability.

description: In many democracies, citizens complain that elections do not provide palatable options - none of the candidates are particularly appealing. More candidates imply more choice, and could potentially increase participation. However, too many candidates may overburden voters and thus discourage participation. In this paper, we use election results and experimental data to show that more candidates results in less participation. Effects are apparent even when comparing ballots with two or three candidates and are not assuaged by party labels. Our results suggest that too much choice on election day can be just as bad as too little.

The development of the information age has put forward higher requirements for memory speed and retention performance. Here, we demonstrate an ultrafast non-volatile memory based on MoS2/h-BN/multi-layer graphene (MLG) van der Waals heterostructures, which has an atomic-level flat interface and achieves ultrafast writing/erasing speed (~20 ns), surpassing the reported state-of-the-art flash memory (~100 ns). The ultrafast flash memory could lay the foundation for the next-generation of high-speed non-volatile memory.

We consider active-sterile neutrino oscillations for a range of mixing parameters: vacuum mass-squared differences of 0.1 eV^2 < dm^2 < 100 eV^2, and vacuum mixing angles of sin^2(2 theta_v) > 10^-4. We find a consistent r-process pattern for a large range of mixing parameters that is in rough agreement with the halo star CS 22892-052 abundances and the pattern shape is determined by fission cycling. We find that the allowed region for the formation of the r-process peaks overlaps the LSND and NSBL (3+1) allowed region.

description: In insulators, the method of Marzari and Vanderbilt [Phys. Rev. B {\bf 56}, 12847 (1997)] can be used to generate maximally localized Wannier functions whose centers are related to the electronic polarization. In the case of layered insulators, this approach can be adapted to provide a natural definition of the local polarization associated with each layer, based on the locations of the nuclear charges and one-dimensional Wannier centers comprising each layer. Here, we use this approach to compute and analyze layer polarizations of ferroelectric perovskite superlattices, including changes in layer polarizations induced by sublattice displacements (i.e., layer-decomposed Born effective charges) and local symmetry breaking at the interfaces. The method provides a powerful tool for analyzing the polarization-related properties of complex layered oxide systems.

description: Infection-related titanium implant failure rates remain exceedingly high in the clinic. Functional surface coating represents a very promising strategy to improve the antibacterial and bioactive properties of titanium alloy implants. Here, we describe a novel bioactive surface coating that consists of a mussel-inspired carboxymethyl chitosan hydrogel loaded with silver nanoparticles (AgNPs) to enhance the bioactive properties of the titanium alloy. The preparation of hydrogel is based on gallic acid grafted carboxymethyl chitosan (CMCS-GA) catalyzed by DMTMM (4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride). To build a firm bonding between the hydrogel and titanium alloy plate, a polydopamine layer was introduced onto the surface of the titanium alloy. With HRP/H2O2 catalysis, CMCS-GA can simply form a firm gel layer on the titanium alloy plate through the catechol groups. The surface properties of titanium alloy were characterized by scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), and water contact angle. Silver nanoparticles were loaded into the gel layer by in situ reduction to enhance the antibacterial properties. In vitro antibacterial and cell viability experiments showed that the AgNPs-loaded Ti-gel possesses excellent antibacterial properties and did not affect the proliferation of rabbit mesenchymal stem cells (MSCs).

description: This article investigates the association between individual-level transnationalism, interactions and cultural skills cutting across European Union (EU) member states, and voting behaviour in the 2019 European elections. The process of EU integration has expanded significantly virtual and physical forms of cross-border mobility in the last decades. Previous works have shown that transnational social exchange furthers Europhile attitudes and dilutes fears for immigrants. Against this backdrop, it is argued that people with high levels of transnationalism have the incentive to vote for parties with pro-EU integration and pro-immigration platforms. Empirical analyses conducted on original public opinion data show that transnational traits significantly affected vote choices in the 2019 European elections. Individual transnationalism is relevant per se in increasing the probability of voting for green and radical-left parties, instead, its negative association with voting for radical right parties runs through EU and immigration attitudes.

description: Interferon lambdas (IFNλ) (also known as type III IFNs) are critical cytokines that combat infection predominantly at barrier tissues, such as the lung, liver, and gastrointestinal tract. Humans have four IFNλs (1–4), where IFNλ1–3 show ~80%–95% homology, and IFNλ4 is the most divergent displaying only ~30% sequence identity. Variants in IFNλ4 in humans are associated with the outcome of infection, such as with hepatitis C virus. However, how IFNλ4 variants impact cytokine signalling in other tissues and how well this is conserved is largely unknown. In this study, we address whether differences in antiviral signalling exist between IFNλ4 variants in human hepatocyte and intestinal cells, comparing them to IFNλ3. We demonstrate that compared to IFNλ3, wild-type human IFNλ4 induces a signalling response with distinct magnitudes and kinetics, which is modified by naturally occurring variants P70S and K154E in both cell types. IFNλ4’s distinct antiviral response was more rapid yet transient compared to IFNλ1 and 3. Additionally, divergent antiviral kinetics were also observed using non-human primate IFNλs and cell lines. Furthermore, an IFNλ4-like receptor-interacting interface failed to alter IFNλ1’s kinetics. Together, our data provide further evidence that major functional differences exist within the IFNλ gene family. These results highlight the possible tissue specialisation of IFNλs and encourage further investigation of the divergent, non-redundant activities of IFNλ4 and other IFNλs.

description: The dynamics of aggregate public opinion – particularly James Stimson’s measure of policy mood – have long been used to explain electoral outcomes and government responsiveness in the United States. However, we still know little about policy mood outside the US and a few Western European countries. Understanding the relationship between policy and preferences outside the pool of advanced democracies is crucial as voters outside that context are often depicted as outcome oriented; that is, they are depicted as voting based on valence issues, where there is shared agreement on the preferred outcome, instead of on a set of coherent policy preferences. We argue that this depiction of voters is attributable to the absence of data in these countries and not to the absence of coherent policy preferences. We test our argument by analyzing nearly three decades of Uruguayan public opinion data including 78 different questions administered 295 times. Our analysis shows that policy preferences across related issues in Uruguay largely move in tandem, suggesting that a coherent policy mood indeed exists. Further, we provide evidence that this policy mood is distinct from symbolic political ideology and that it responds thermostatically to changes in government. This thermostatic responsiveness suggests that Uruguayans do not merely focus on whether the economy is good or bad but, rather, update their policy preferences in response to the direction of government policy. Together, these results offer a much more nuanced depiction of public opinion outside advanced industrial democracies than previous research suggests, with important implications for democratic accountability in Latin America and other developing economies.
Minimum divergence estimators, Maximum Likelihood and the generalized bootstrap
Creators: name: Broniatowski, Michel
Publisher: name: arXiv
Year: 2020
Subjects: subject: Statistics Theory (math.ST)

description: This paper is an attempt to set a justification for making use of some dicrepancy indexes, starting from the classical Maximum Likelihood definition, and adapting the corresponding basic principle of inference to situations where minimization of those indexes between a model and some extension of the empirical measure of the data appears as its natural extension. This leads to the so called generalized bootstrap setting for which minimum divergence inference seems to replace Maximum Likelihood one. 1 Motivation and context Divergences between probability measures are widely used in Statistics and Data Science in order to perform inference under models of various kinds, paramet-ric or semi parametric, or even in non parametric settings. The corresponding methods extend the likelihood paradigm and insert inference in some minimum "distance" framing, which provides a convenient description for the properties of the resulting estimators and tests, under the model or under misspecifica-tion. Furthermore they pave the way to a large number of competitive methods , which allows for trade-off between efficiency and robustness, among others. Many families of such divergences have been proposed, some of them stemming from classical statistics (such as the Chi-square), while others have their origin in other fields such as Information theory. Some measures of discrepancy involve regularity of the corresponding probability measures while others seem to be restricted to measures on finite or countable spaces, at least when using them as inferential tools, henceforth in situations when the elements of a model have to be confronted with a dataset. The choice of a specific discrepancy measure in specific context is somehow arbitrary in many cases, although the resulting conclusion of the inference might differ accordingly, above all under misspecification; however the need for such approaches is clear when aiming at robustness.
Recombination Lines and Free-Free Continua formed in Asymptotic Ionized Winds: Analytic solution for the radiative transfer
Creators: name: Ignace, Richard
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In dense hot star winds, the infrared and radio continua are dominated by free-free opacity and recombination emission line spectra. In the case of a spherically symmetric outflow that is isothermal and expanding at constant radial speed, the radiative transfer for the continuum emission from a dense wind is analytic. Even the emission profile shape for a recombination line can be derived. Key to these derivations is that the opacity scales with only the square of the density. These results are well-known. Here an extension of the derivation is developed that also allows for line blends and the inclusion of an additional power-law dependence beyond just the density dependence. The additional power-law is promoted as a representation of a radius dependent clumping factor. It is shown that differences in the line widths and equivalent widths of the emission lines depend on the steepness of the clumping power-law. Assuming relative level populations in LTE in the upper levels of He {\sc ii}, an illustrative application of the model to {\em Spitzer}/IRS spectral data of the carbon-rich star WR 90 is given.

description: We propose to use ultra-high intensity laser pulses with wavefront rotation (WFR) to produce short, ultra-intense surface plasma waves (SPW) on grating targets for electron acceleration. Combining a smart grating design with optimal WFR conditions identified through simple analytical modeling and particle-in-cell simulation allows to decrease the SPW duration (down to few optical cycles) and increase its peak amplitude. In the relativistic regime, for $Iλ_0^2=3.4 \times 10^{19}{\rm W/cm^2μm^2}$, such SPW are found to accelerate high-charge (few 10's of pC), high-energy (up to 70 MeV) and ultra-short (few fs) electron bunches.
Living with the demented: experiences and recommendations of elderly non-demented nursing home residents
Creators: name: Paul, Andrew Glen
Publisher: name: University of British Columbia
Year: 2009

description: This study was designed to investigate the experiences and recommendations of elderly non-demented nursing home residents regarding living with the demented, or integration. It was designed to provide descriptive information about the nature and amount of residents' awareness of the demented within their nursing homes, the lifestyle impacts of integration, residents' affective/attitudinal responses to integration, and their integration policy recommendations. A purposive sample of 102 non-demented residents of five Vancouver nursing homes completed a newly-devised client-centered questionnaire. Uni-variate and bi-variate data analysis was done. The results of this study indicate that almost all residents (93%) had some contact with the demented, two thirds (63%) on a daily basis. A lesser number (81%) thought about the demented, half of those (41%) daily. A roughly even split occurred between those with no demented friends (47%) and those with at least one (53%). Most residents (72%) reported that integration had minimal negative impact upon their lifestyle. One in four residents(28%), however, experienced disruption to their daily routines and/or made a conscious effort to modify their lifestyle within the nursing home on a regular basis. Just over half of the residents (54%) had a neutral affective/attitudinal response to integration, and among those who were not neutral (46%), a pattern emerged of residents feeling unhappiness, dislike, unease, and pessimism, but also not ashamed. Four out of five residents (81%) recommended an integration policy that incorporated some degree of separation. Increased contact was directly related to increased thought about the demented, pessimism, and feeling unsafe. Those with at least one demented friend tended to feel slightly more at ease, to like integration, and to recommend it. Those who recommended separation also tended to avoid the demented and social/recreational activities with them, to feel uneasy, unsafe, ashamed, pessimistic, and unhappy about integration, and to dislike living with the demented. These findings raise question about the suitability of integration for the non-demented. Further client-centered research is recommended to investigate more fully the multi-dimensional effects of integration upon the non-demented and the preferences of this population regarding this crucial determinant of their social environment.

description: We consider two dimensional non linear sigma models on few symmetric superspaces, which are supergroup manifolds of coset type. For those spaces where one loop beta function vanishes, two loop beta function is calculated and is shown to be zero. Vanishing of beta function in all orders of perturbation theory is shown for the principal chiral models on group supermanifolds with zero Killing form. Sigma models on symmetric (super) spaces on supergroup manifold $G/H$ are known to be classically integrable. We investigate a possibility to extend an argument of absence of quantum anomalies in non local current conservation from non super case to the case of supergroup manifolds which are asymptotically free in one loop.

description: Which voters hold polarized affects for political parties in Western Europe? We consider distinct characteristics of different political issues that shape political actors’ behaviors and argue that voters are more affectively polarized when they put salience on cultural issues because their stances on the issues are embedded in their deep-seated identity, value, belief, and morality. Empirically, we use measures of affective polarization that incorporate the multiparty systems of Western European countries. Using the Comparative Study of Electoral Systems (Module 3), we find that voters who put salience on cultural issues are more affectively polarized than others. The result implies that rising affective polarization in the past decades might have been related to increasing priorities on cultural issues. It also implies that political parties may potentially weaken voters’ affective polarization by manipulating their issue agenda.
Negative magnetoresistance and phase slip process in superconducting nanowires

description: We argue that the negative magnetoresistance of superconducting nanowires, which was observed in recent experiments, can be explained by the influence of the external magnetic field on the critical current of the phase slip process. We show that the suppression of the order parameter in the bulk superconductors made by an external magnetic field can lead to an enhancement of both the first $I_{c1}$ and the second $I_{c2}$ critical currents of the phase slip process in nanowires. Another mechanism of an enhancement of $I_{c1}$ can come from decreasing the decay length of the charge imbalance $λ_Q$ at weak magnetic fields because $I_{c1}$ is inversely proportional to $λ_Q$. The enhancement of the first critical current leads to a larger intrinsic dissipation of the phase slip process. It suppresses the rate of both the thermo-activated and/or quantum fluctuated phase slips and results in decreasing the fluctuated resistance.

description: Shell models have found wide application in the study of hydrodynamic turbulence because they are easily solved numerically even at very large Reynolds numbers. Although bereft of spatial variation, they accurately reproduce the main statistical properties of fully-developed homogeneous and isotropic turbulence. Moreover, they enjoy regularity properties which still remain open for the three-dimensional (3D) Navier-Stokes equations (NSEs). The goal of this study is to make a rigorous comparison between shell models and the NSEs. It turns out that only the estimate of the mean energy dissipation rate is the same in both systems. The estimates of the velocity and its higher-order derivatives display a weaker Reynolds number dependence for shell models than for the 3D NSEs. Indeed, the velocity-derivative estimates for shell models are found to be equivalent to those corresponding to a velocity gradient averaged version of the 3D Navier-Stokes equations (VGA-NSEs), while the velocity estimates are even milder. Numerical simulations over a wide range of Reynolds numbers confirm the estimates for shell models.

description: The Wilson loop in some non-commutative gauge theories is studied by using the dual string description in which the corresponding string is on the curved background with B field. For the theory in which a constant B field is turned on along the brane worldvolume the Wilson loop always shows a Coulomb phase, as studied in the previous literature. We extend the examination to the theory with a non-constant B field, which duals to the gauge theory with non-constant non-commutativity, and re-examine the theory in the presence of a nonzero B field with one leg along the brane worldvolume and other transverse to it, which duals to a non-commutative dipole theory. The expectation value of the Wilson loop is calculated to the lowest order by evaluating the area of the string worldsheet. The results show that, while the non-commutativity could modify the Coulomb type potential in IR it may produce a strong repulsive force between the quark and anti-quark if they are close enough. In particular, we find that there presents a minimum distance between the quarks and that the distance is proportional to the value of the non-commutativity, exhibiting the nature of the non-commutative theory.

description: This paper investigates whether personality affects support for populist parties either directly or indirectly through “populist attitudes.” It theorizes that populist attitudes should be disambiguated into their component facets and that the attitudinal components of populism are best understood as loosely related characteristic adaptations, which mediate the relationship between personality and vote choice. Using data from a nationally representative survey of 2200 Australians fielded prior to the general election in 2019, the paper demonstrates that the three attitudinal components of populism (People-centrism, Anti-elitism, and a Manichean outlook) are weakly associated with one another and distinctively connected with underlying personality traits. Our results indicate that populist attitudes are better conceptualized as a cluster of weakly related psychological tendencies rather than as a coherent worldview or personality. Mediation analysis indicates that personality traits affect support for populist parties both directly and indirectly through the attitudinal components of populism.

description: Here we discuss the annealing behavior of an infinite-range $\pm J$ Ising spin glass in presence of a transverse field using a zero-temperature quantum Monte Carlo. Within the simulation scheme, we demonstrate that quantum annealing not only helps finding the ground state of a classical spin glass, but can also help simulating the ground state of a quantum spin glass, in particularly, when the transverse field is low, much more efficiently.

description: Rumination, or negative repetitive thinking, is a significant risk factor for depression and a common and pervasive habit of thought. Using original data from two online surveys of British adults conducted in March 2021 and February 2022, we examine associations between measures of political engagement and the two types of depressive rumination computed from Nolen-Hoeksema’s Response Styles Theory: brooding (the maladaptive component that assesses negative aspects of self-reflection) and reflective pondering (the adaptive component focused on problem-solving). We show that (1) higher brooding is associated with lower internal political efficacy and voting; (2) higher reflective pondering is associated with higher external political efficacy; and (3) reflective pondering increases voting propensity for nonpartisans but not for partisans. Thus, while maladaptive rumination is detrimental to political engagement, adaptive rumination appears to be beneficial. Our findings advance our understanding of the role of reflection in democratic citizenship.
The matter power spectrum in f(R) gravity

description: Modified gravity can be considered as an alternative to dark energy. In a generalized theory of gravity, the universe may accelerate while containing only baryonic and dark matter. We study, in particular, the evolution of matter fluctuations in f(R) models within the Palatini approach, and find that the resulting matter power spectrum is sensitive to a nonlinear dependence on the curvature scalar in the gravitational action. The constraints that arise from comparison to the form of the observed matter power spectrum tighten the previous constraints derived from background expansion by several orders of magnitude. Models in the allowed parameter space are practically indistinguishable from general relativity with a cosmological constant when the backround expansion is considered.

description: Increasing fluorescence quantum yields of ligand-protected gold nanoclusters has attracted wide research interest. The strategy consisting in using bulky counterions has been found to dramatically enhance the fluorescence. In this communication, we push forward this concept to the nonlinear optical regime. We show that by an appropriate choice of bulky counterions and of solvent, a 30-fold increase in two-photon excited fluorescence (TPEF) signal at ~600 nm for gold nanoclusters can be obtained. This would correspond to a TPEF cross section in the range of 0.1 to 1 GM.

description: Polymer-based hydrogels have been widely applied for chronic wound therapeutics, due to their well-acclaimed wound exudate management capability. At the same time, there is still an unmet clinical need for simple wound diagnostic tools to assist clinical decision-making at the point of care and deliver on the vision of patient-personalised wound management. To explore this challenge, we present a one-step synthetic strategy to realise a redox-responsive, hyaluronic acid (HA)-based hydrogel that is sensitive to wound environment-related variations in glutathione (GSH) concentration. By selecting aminoethyl disulfide (AED) as a GSH-sensitive crosslinker and considering GSH concentration variations in active and non-self-healing wounds, we investigated the impact of GSH-induced AED cleavage on hydrogel dimensions, aiming to build GSH-size relationships for potential point-of-care wound diagnosis. The hydrogel was also found to be non-cytotoxic and aided L929 fibroblast growth and proliferation over seven days in vitro. Such a material offers a very low-cost tool for the visual detection of a target analyte that varies dependent on the status of the cells and tissues (wound detection) and may be further exploited as an implant for fibroblast growth and tissue regeneration (wound repair).
Analysing Uncertainties in Offshore Wind Farm Power using Measure Correlate Predict Methodologies.

description: This study builds on recent analysis (Mifsud, et al., 2018) in which uncertainties in predicting long term wind speeds using different Measure Correlate Predict methodologies were compared. These included the Simple Linear Regression, Artificial Neural Networks, Decision Trees and Support Vector Regression.   The current work focuses on the uncertainties resulting from the different MCP methods to predict the power and energy yield from a wind farm. The analysis is based on a case study that utilizes short-term data acquired from a LiDAR system deployed in a coastal site in the northern part of the island of Malta and long-term measurements from the island’s airport. LiDAR measurements at various heights, ranging from 10 to 200m are considered. A hypothetical offshore wind farm layout consisting of 50 turbines rated at 5-MW each is assumed. The wind farm faces the north-west direction, which is the prevailing wind direction for the island archipelago. The turbines are placed in rows of ten wind turbines each, with a cross-wind inter-turbine spacing set at five rotor diameters and a downwind spacing of eight rotor diameters between successive rows. The predicted power output from the various MCP methodologies is compared to the actual power output obtained directly from the input of LiDAR data to establish which MCP methodology best predicts the output power.   The different MCP methods, that were implemented in Matlab®, are used to predict the absolute wind speed, while wind direction is predicted using the same regression methodology but, using the vector components of the wind. The wind direction is then calculated from the predicted vector components.   The power output from the wind farm is predicted by inputting wind speed and direction into WindPro®, using a Risø/EMD (N.Ø. Jensen) wake model and a standard 5-MW wind turbine. The wake model introduces a more realistic value of the power output for the wind farm, as it includes the shadowing effects on the wind turbines and the wind direction. The power is predicted for a range of wind turbines (from 10 to 50, in steps of 10) and at hub heights of 30, 80, 100, 150 and 200m. The predicted power is compared to the power output generated from the actual wind and direction data by using the Mean Squared Error (MSE) and the Mean Absolute Error (MAE). This methodology will establish which combination of MCP methodology and wind farm configuration will have the least prediction error.
