description: We report on gigahertz acoustic phonon waveguiding in free-standing single copper nanowires studied by femtosecond transient reflectivity measurements. The results are discussed on the basis of the semianalytical resolution of the Pochhammer and Chree equation. The spreading of the generated Gaussian wave packet of two different modes is derived analytically and compared with the observed oscillations of the sample reflectivity. These experiments provide a unique way to independently obtain geometrical and material characterization. This direct observation of coherent guided acoustic phonons in a single nano-object is also the first step toward nanolateral size acoustic transducer and comprehensive studies of the thermal properties of nanowires.

description: There is a growing need to semantically process and integrate clinical data from different sources for clinical research. This paper presents an approach to integrate EHRs from heterogeneous resources and generate integrated data in different data formats or semantics to support various clinical research applications. The proposed approach builds semantic data virtualization layers on top of data sources, which generate data in the requested semantics or formats on demand. This approach avoids upfront dumping to and synchronizing of the data with various representations. Data from different EHR systems are first mapped to RDF data with source semantics, and then converted to representations with harmonized domain semantics where domain ontologies and terminologies are used to improve reusability. It is also possible to further convert data to application semantics and store the converted results in clinical research databases, e.g. i2b2, OMOP, to support different clinical research settings. Semantic conversions between different representations are explicitly expressed using N3 rules and executed by an N3 Reasoner (EYE), which can also generate proofs of the conversion processes. The solution presented in this paper has been applied to real-world applications that process large scale EHR data.

description: This study investigates how students’ positive and negative emotions changed after the outbreak of COVID-19 and the related campus closure. We expect that the impact of the COVID-related stressors on students’ emotions was moderated by students’ personality (emotional stability), mental health and experienced restrictions of college and study activities. Furthermore, we examine mental health as both a predictor and outcome of stress reactivity in the face of a major stressor - the COVID-19 pandemic.

description: In this letter, we propose a practical non-linear energy harvesting model and design a resource allocation algorithm for simultaneous wireless information and power transfer (SWIPT) systems. The algorithm design is formulated as a non-convex optimization problem for the maximization of the total harvested power at energy harvesting receivers subject to minimum required signal-to-interference-plus-noise ratios (SINRs) at multiple information receivers. We transform the considered non-convex objective function from sum-of-ratios form into an equivalent objective function in subtractive form, which enables the derivation of an efficient iterative resource allocation algorithm. In each iteration, a rank-constrained semidefinite program (SDP) is solved optimally by SDP relaxation. Numerical results unveil a substantial performance gain that can be achieved if the resource allocation design is based on the proposed non-linear energy harvesting model instead of the traditional linear model.

description: The mutually enriching relationship between graphs and matroids has motivated discoveries in both fields. In this paper, we exploit the similar relationship between embedded graphs and delta-matroids. There are well-known connections between geometric duals of plane graphs and duals of matroids. We obtain analogous connections for various types of duality in the literature for graphs in surfaces of higher genus and delta-matroids. Using this interplay, we establish a rough structure theorem for delta-matroids that are twists of matroids, we translate Petrie duality on ribbon graphs to loop complementation on delta-matroids, and we prove that ribbon graph polynomials, such as the Penrose polynomial, the characteristic polynomial, and the transition polynomial, are in fact delta-matroidal. We also express the Penrose polynomial as a sum of characteristic polynomials.

description: Das Christentum hat einen starken Einfluss auf das Leben der Pacific Islander. Dieser beschränkt sich nicht nur auf das tägliche Beten und die sonntäglichen Kirchgänge, sondern geht weit über den zu erwartenden Rahmen hinaus. Mit ihrer Forschung über den Einfluss des christlichen Glaubens auf den Umgang von Pacific Islandern mit dem globalen Klimawandel beleuchtet die Autorin, wie weitreichend und wirkungsstark das Christentum im alltäglichen Leben und Weltverständnis der Menschen verankert ist. Zudem zeigt sie auf, welches Potential Wissenschaftler*innen, Pastoren und Gläubige dem Christentum zuschreiben, um die Bewohner Ozeaniens zu erreichen und zu einem aktiven und nachhaltiges Verständnis des globalen Klimawandels zu bemächtigen. Sie plädiert hierbei nicht nur für eine starke interdisziplinäre Zusammenarbeit zwischen Natur-, Human- und Sozialwissenschaften, sondern auch für die Aufhebung der strikten Trennung zwischen Religion und Wissenschaft, um dem globalen Klimawandel holistisch zu betrachten, eine globale Ethik des Klimawandels zu entwickeln und praxisorientierte Forschung zu betreiben.
description: Christianity is deeply embedded in the life of Pacific Islanders. The impact of Christianity on peoples’ lives goes far beyond their daily praying and visiting the Sunday church service. With her thesis on the significance of Christianity on dealing with climate change the author reveals the important and far reaching impact religion has on the daily routine and world view of the Pacific Islanders. She depicts the unique potential that scientists, pastors and fellow believers assign religion to reach and to empower the Pacific Islanders in an active understanding and handling of global climate change. Furthermore, the author advocates for an interdisciplinary collaboration of natural, human and social sciences as well as the abolition of the dualistic categories of religion and science in order to engage in a holistic examination of global climate change, to develop a global ethics of climate change, and to undertake practice-oriented research.

description: We report on the magnetic properties of Eu$_{2}$Ir$_{2}$O$_{7}$ upon the application of hydrostatic pressure $P$ by means of macroscopic and local-probe techniques. In contrast to previously reported resistivity measurements, our dc magnetization data unambiguously demonstrate a non-monotonic $P$-dependence for $T_{N}$, i.~e., the critical transition temperature to the magnetic phase. More strikingly, we closely reproduce the recently calculated behaviour for $T_{N}$ under the assumption that $P$ lowers the $U/W$ ratio (i.~e., Coulomb repulsion energy over electronic bandwidth). Zero-field muon-spin spectroscopy measurements confirm that the local magnetic configuration is only weakly perturbed by low $P$ values, in agreement with theoretical predictions. The current results experimentally support the preservation of a $4$-in/$4$-out ground state and, simultaneously, a departure from the single-band $j_{\text{eff}} = 1/2$ model across the accessed region of the phase diagram.

description: Energetics of nuclear reaction is fundamentally important to understand the mechanism of pair instability supernovae (PISNe). Based on the hydrodynamic equations and thermodynamic relations, we derive exact expressions for energy conservation suitable to be solved in simulation. We also show that some formulae commonly used in the literature are obtained as approximations of the exact expressions. We simulate the evolution of very massive stars of ~100-320 Msun with zero- and 1/10 Zsun, and calculate further explosions as PISNe, applying each of the exact and approximate formulae. The calculations demonstrate that the explosion properties of PISN, such as the mass range, the 56Ni yield, and the explosion energy, are significantly affected by applying the different energy generation rates. We discuss how these results affect the estimate of the PISN detection rate, which depends on the theoretical predictions of such explosion properties.

Intersection Homology. General perversities and topological invariance

description: Topological invariance of the intersection homology of a pseudomanifold without codimension one strata, proven by Goresky and MacPherson, is one of the main features of this homology. This property is true for codimension-dependent perversities with some growth conditions, verifying $\overline p(1)=\overline p(2)=0$. King reproves this invariance by associating an intrinsic pseudomanifold $X^*$ to any pseudomanifold $X$. His proof consists of an isomorphism between the associated intersection homologies $H^{\overline{p}}_{*}(X) \cong H^{\overline{p}}_{*}( X^*)$ for any perversity $\overline{p}$ with the same growth conditions verifying $\overline p(1)\geq 0$. In this work, we prove a certain topological invariance within the framework of strata-dependent perversities, $\overline{p}$, which corresponds to the classical topological invariance if $\overline{p}$ is a GM-perversity. We also extend it to the tame intersection homology, a variation of the intersection homology, particularly suited for ``large'' perversities, if there is no singular strata on $X$ becoming regular in $X^*$. In particular, under the above conditions, the intersection homology and the tame intersection homology are invariant under a refinement of the stratification.
Boardroom Networks and Political Ideology in Shaping Firms’ Environmental Strategies
Creators: name: Chen, Mingyuan
Publisher: name: Lancaster University
Year: 2023

description: This thesis aims to study how firms’ environmental strategies are shaped with a focus on board directors. For this study, I compile the Database on Director Network, Toxic Releases and Political Activities and use toxic releases from the US Environmental Protection Agency (EPA)’s Toxics Release Inventory (TRI) Program as the key environmental performance indicator. By using the database compiled, I first study how director networks are formed. My findings show that firms are likely to appoint influential directors with good environmental performances. Further, directors with environmental characteristics similar to the other board members or their firm are more likely to be chosen as board members. I also show that boards of directors with good environmental performances or in which directors have diverse environmental performance backgrounds will improve firms’ environmental quality. Then I examine the effect of political ideology in shaping firms’ environmental strategies. My results show that although political ideology is less significant in determining a firm’s environmental strategy than board directors’ previous environmental performance records, Republican-leaning firms have poorer environmental performances. To address the endogenous concerns, I also follow a similar approach to study network formation with the inclusion of politics-related measures and find firms also tend to appoint directors who share similar political ideologies. These findings help to explain the political polarization in the private sector from a network formation aspect and provide further evidence of the role of political ideology in shaping environmental strategies.
Helicopter Main Gearbox Planetary Bearing Fault Diagnosis using Vibration Signal Processing Techniques
Creators: name: Zhou, Linghao
Publisher: name: London South Bank University
Year: 2020

description: Helicopters are extensively employed as versatile assets for military, transportation, rescue and many other utilities. A healthy and functional Helicopter Main Gearbox (MGB) is critical to ascertain the helicopter’s system reliability and flight airworthiness, i.e. the suitability for safe flight. Therefore, it is of great importance to monitor the health status of the MGB. Currently, Health and Usage Monitoring System (HUMS), has been deployed on all medium and large size civil helicopters to perform MGB health status monitoring in United Kingdom. Nevertheless, HUMS has shown insensitivities and a lack of accuracy to detect planetary bearings-related defects, resulting in unfortunate accidents. Therefore, the successful diagnosis of planetary bearing defects in MGB could contribute profoundly to enhance sensitivity of HUMS against such defect type, thus improving helicopter flight safety, and reducing the overall maintenance costs. This research aims at investigating the diagnosis of planetary bearing faults inside MGB using advanced signal processing techniques, providing diagnostic information that is more accurate and indicative against incipient planetary bearing faults. To fulfil the requirements, experimental work was undertaken on a commercial helicopter MGB to acquire invaluable vibration data. The MGB was operated under various load, speed and fault severities conditions. Diagnosis of the seeded planetary bearing faults was then successfully performed by evaluating and implementing various frequency domain processing techniques. Finally, further evaluation was conducted using another MGB dataset collected from a CH-46E Aft gearbox. The results of this study have shown that applying various frequency domain signal processing techniques can effectively detect incipient planetary bearing faults. The main contributions of this research include acquiring data from a full scale helicopter main gearbox, proposing and evaluating a non-deterministic weak signature analysis scheme for MGB planetary bearings fault detection, and demonstrating using MGB carrier induced sidebands as a novel spectral feature for planetary bearing diagnosis.

description: We develop a theoretical model, relying on the well established sp3 bond-orbital theory, to describe the strain-induced $χ^{(2)}$ in tetrahedrally coordinated centrosymmetric covalent crystals, like silicon. With this approach we are able to describe every component of the $χ^{(2)}$ tensor in terms of a linear combination of strain gradients and only two parameters $α$ and $β$ which can be estimated theoretically. The resulting formula can be applied to the simulation of the strain distribution of a practical strained silicon device, providing an extraordinary tool for optimization of its optical nonlinear effects. By doing that, we were able not only to confirm the main valid claims known about $χ^{(2)}$ in strained silicon, but also estimate the order of magnitude of the $χ^{(2)}$ generated in that device.

Camp Rock Fault Slip Rate and Folding of the Lenwood Anticline: Contributions to Eastern California Shear Zone Strain Accumulation
Creators: name: Gurney, Emily
Publisher: name: University of North Carolina at Chapel Hill
Year: 2008

description: Geologic mapping, 10Be geochronology, and fold modeling provide insight into reconciling discrepant geologic and geodetic slip rates across a portion of the eastern California shear zone. The Camp Rock fault is one of six faults that make up the shear zone. Two alluvial fans of different generations, offset by the fault, yield ages of 100 plus minus 30 ka and 56.4 plus minus 7.7 ka. Offsets on these fans are 41 plus minus 25 m and 22 plus minus 2 m respectively, yielding a long-term slip rate of 0.4 plus 0.3/ minus 0.1 mm/yr for the fault. This is only 2-7% of the geodetic strain rate across the shear zone. The Camp Rock fault terminates northward into the Lenwood anticline. Modeling of this fold indicates ~3.8 km of north-south shortening, of which ~1.0-2.4 km is not transferred to Camp Rock fault slip but is maintained east of the fault. Such regionally distributed shortening may help to reconcile geologic and geodetic strain rates.

description: Remote therapy promises a cost-effective way of increasing delivery of psychological-therapy in underserved populations. However, research shows a “digital divide”, with some groups experiencing digital exclusion. To assess whether technology, accessibility, and demographic factors influence remote therapy uptake among individuals with psychosis, and whether demographic factors are associated with digital exclusion. Remote therapy uptake and demographics were assessed in people (n = 51) within a psychology-led service for psychosis, using a survey of access to digital hardware, data and private space. The majority of individuals had access to digital devices, but 29% did not meet minimum requirements for remote therapy. Nineteen (37%) individuals declined remote therapy. Those who accepted were significantly younger and more likely to have access to technology than those who declined. The mean age of those with access to smartphones and large screen devices was younger than those without access. A subgroup of people with psychosis face barriers to remote therapy and a significant minority are digitally excluded. Older age is a key factor influencing remote therapy uptake, potentially related to less access to digital devices. Services must minimize exclusion through provision of training, hardware and data, whilst promoting individual choice.

description: At TU Darmstadt, the Accurate Laser Involved Voltage Evaluation (ALIVE) experiment, which uses the technique of collinear laser spectroscopy to perform high voltage measurements to a high degree of precision, is carried out at the COALA beamline. In such laser spectroscopy beamlines, iris diaphragms are used to reduce ion beam divergence, and to ensure a good laser and ion beam overlap. Since the system that controls the diameter of the apertures presents strong hysteresis, an automated adjustment is desirable to enhance reproducibility in the aperture settings, and to reduce the effort in performing measurements where different diameters are required. To achieve this, the Iris Mover system was designed and implemented. The Iris Mover system consists of motor-driven iris apertures which can be easily controlled by users through a computer, and which accounts for hysteresis effects.

description: Alain Connes and Nigel Higson pointed out in the 1990s that the Connes-Kasparov "conjecture"' for the K-theory of reduced groupe $C^\ast$-algebras seemed, in the case of reductive Lie groups, to be a cohomological echo of a conjecture of George Mackey concerning the rigidity of representation theory along the deformation from a reductive Lie group to its Cartan motion group. For complex semisimple groups, Nigel Higson established in 2008 that Mackey's analogy is a real phenomenon and does lead to a simple proof of the Connes-Kasparov isomorphism. We here turn to more general reductive groups and use our recent work on Mackey's proposal, together with Higson's work, to obtain a new proof of the Connes-Kasparov isomorphism.

An Economic Signaling Comparison of High School Diploma to General Education Development Certificate Holders in the United States Army
Creators: name: Maxfield, Brooke
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Potential employees alert employers of their ability levels and occupational skills through education and education credentials during the hiring process. As such, education serves as a sorting mechanism for potential employees by their work-related characteristics such as perseverance, determination, ability, productivity, and so forth (Page, 2010; Riley, 1979). Military attrition studies of the 1980s found that education credentials were positively correlated to military retention and reinforced the premise of economic credentialing theory (National Library of Education, 1998). Therefore, the military developed a three-tier system that was based on the education credentials of new recruits. This system is still used by the Army to assess the qualifications of those who serve in the military. Employers also rely on employee characteristics viewed as useful in the work environment, referred to as education signaling. Education signaling allows for consideration of job performance covariates that go beyond schooling or credentials (e.g., aptitude-test scores, race, gender; Kjelland, 2008; Weiss, 1983, 1995). This study focuses on the influence of Army enlisted soldiers’ education credentials and signaling on their occupational success via retention and promotion. The sample consisted of over 150,000 non-prior service enlisted Army soldiers with traditional high school or general education credentials in three cohort groups over 4 years each, from 2004 to 2012. The data was analyzed by cross-tabulation and logistic regression. On the basis of the findings, the 1980s military retention studies were validated in terms of retention and promotion. Additionally, the results confirmed that the economic signaling that is present in the general labor market also exists in the meritocracy of the U.S. Army. Specifically, education credentials are a strong predictor for retention; AFQT scores are a strong predictor of promotion; and race of the soldier is related to both retention and promotion. The results support the Army’s use of both education credentials and AFQT scores for enlistment screening and the military tier system. Further research is necessary to reveal why race has an impact on Army retention and promotion, and to determine if aptitude tests are appropriate for hiring and promotion decisions in the general labor market.

description: National Health Service use the Community Mental Health Service User Questionnaire (NHS-CMH) to assess care quality. However, its reliability and internal validity is uncertain. To test the NHS-CMH structure, reliability and item-level characteristics. We used data from 11,373 participants who answered the 2017 NHS-CMH survey. First, we estimated the NHS-CMH structure using Exploratory Factor Analysis (EFA) in half of the dataset. Second, we tested the best EFA-derived model with Confirmatory Factor Analysis (CFA). We tested the internal validity, construct reliability (omega – ω), explained common variance of each factor (ECV), and item thresholds. EFA suggested a 4-factor solution. The structure derived from the EFA was confirmed, demonstrating good reliability for the four correlated dimensions: “Relationship with Staff” (ω = 0.952, ECV = 40.1%), “Organizing Care” (ω = 0.855, ECV = 21.4%), “Medication and Treatments” (ω = 0.837, ECV = 13.3%), and “Support and Well-being” (ω = 0.928, ECV = 25.3%). A second-order model with a high-order domain of “Quality of Care” is also supported. The NHS-CMH can be used to reliably assess four user-informed dimensions of mental health care quality. This model offers an alternative for its current use (item-level and untested sum scores analysis).

description: Full-dimensional (12D) vibrational states of the methanol molecule (CH$_3$OH) have been computed using the GENIUSH-Smolyak approach and the potential energy surface from Qu and Bowman (2013). All vibrational energies are converged better than 0.5 cm$^{-1}$ with respect to the basis and grid size up to the first overtone of the CO stretch, ca. 2000 cm$^{-1}$ beyond the zero-point vibrational energy. About seventy torsion-vibration states are reported and assigned. The computed vibrational energies agree with the available experimental data within less than a few cm$^{-1}$ in most cases, which confirms the good accuracy of the potential energy surface. The computations are carried out using curvilinear normal coordinates with the option of path-following coefficients which minimize the coupling of the small- and large-amplitude motions. It is important to ensure tight numerical fulfilment of the $C_{3\mathrm{v}}$(M) molecular symmetry for every geometry and coefficient set used to define the curvilinear normal coordinates along the torsional coordinate to obtain a faithful description of degeneracy in this floppy system. The reported values may provide a computational reference for fundamental spectroscopy, astrochemistry, and for the search of the proton-to-electron mass ratio variation using the methanol molecule.

description: Spatially indirect electron-hole exciton condensates stabilized by interlayer Fock exchange interactions have been predicted in systems containing a pair of two-dimensional semiconductor or semimetal layers separated by a thin tunnel dielectric. The layer degree of freedom in these systems can be described as a pseudospin. Condensation is then analogous to ferromagnetism, and the interplay between collective and quasiparticle contributions to transport is analogous to phenomena that are heavily studied in spintronics. These phenomena are the basis for pseudospintronic device proposals based on possible low-voltage switching between high (nearly shorted) and low interlayer conductance states and on near perfect Coulomb drag-counterflow current along the layers. In this work, a quantum transport simulator incorporating a non-local Fock exchange interaction is presented, and used to model the essential transport physics in the bilayer graphene system. Finite size effects, Coulomb drag-counterflow current, critical interlayer currents beyond which interlayer DC conductance collapses at sub-thermal voltages, non-local coupling between interlayer critical currents in multiple lead devices, and an Andreev-like reflection process are illustrated.

description: We consider the Whitham equation $u_t + 2u u_x+Lu_x = 0$, where L is the nonlocal Fourier multiplier operator given by the symbol $m(ξ) = \sqrt{\tanh ξ/ξ}$. G. B. Whitham conjectured that for this equation there would be a highest, cusped, travelling-wave solution. We find this wave as a limiting case at the end of the main bifurcation curve of $P$-periodic solutions, and give several qualitative properties of it, including its optimal $C^{1/2}$-regularity. An essential part of the proof consists in an analysis of the integral kernel corresponding to the symbol $m(ξ)$, and a following study of the highest wave. In particular, we show that the integral kernel corresponding to the symbol $m(ξ)$ is completely monotone, and provide an explicit representation formula for it.

description: We present experimental evidence of a thermoelectric effect at the interface between two liquid metals. Using superimposed layers of mercury and gallium in a cylindrical vessel operating at room temperature, we provide a direct measurement of the electric current generated by the presence of a thermal gradient along a liquid-liquid interface. At the interface between two liquids, temperature gradients induced by thermal convection lead to a complex geometry of electric currents, ultimately generating current densities near boundaries that are significantly higher than those observed in conventional solid-state thermoelectricity. When a magnetic field is applied to the experiment, an azimuthal shear flow, exhibiting opposite circulation in each layer, is generated. Depending on the value of the magnetic field, two different flow regimes are identified, in good agreement with a model based on the spatial distribution of thermoelectric currents, which has no equivalent in solid systems. Finally, we discuss various applications of this new effect, such as the efficiency of liquid metal batteries.

description: Mental distress is an important public health problem and is becoming common health problems among university students. This study aimed to provide a pooled prevalence of mental distress and associated factors among university students in Ethiopia. We systematically searched PubMed, EMBASE and PsycINFO databases. A further search was performed at Google Scholar search engine for additional studies. All observational studies reporting the prevalence of mental distress and/or associated factors among university students in Ethiopia were included. Pooled prevalence with 95% confidence interval (95% CI) were calculated using random effects and quality effects models. Subgroup and sensitivity analyses were performed. Heterogeneity between studies and evidence of publication bias were assessed. The pooled prevalence of mental distress was 35% (95% CI; 28%–43%). Being female, participating in religious programmes, having close friends, experiencing financial distress, alcohol use, khat use, conflict with friends, lack of interest in their field of study and a family history of mental illness were factors associated with mental distress among students. We found significant heterogeneity, but no evidence of publication bias. More than one third of university students in Ethiopia have suffered with mental distress. The finding provides evidence that university students are at risk population for mental health problems and suggests the need for early intervention to prevent severe mental illness.
On mechanism of high-temperature superconductivity in hydrogen sulfide at 200 GPa: transition into superconducting anti-adiabatic state in coupling to H-vibrations

description: We have shown that adiabatic electronic structure of superconducting phase of sulphur hydride at 200 GPa is unstable toward vibration motion of H-atoms. Theoretical study indicates that in coupling to H-vibrations, system undergoes transition from adiabatic into stabilised anti-adiabatic multi-gap superconducting state at temperature which can reach 203 K.

How Italian Elder Care and Immigration Policies Disproportionately Provide Job Security to Female Migrants

description: Between the years of 2005-2013 foreign-born females living in Italy enjoyed a period of relative job stability despite the fact that the labor market endured a number of external shocks (i.e. the economic crisis, increased migrant flows, low levels of economic growth). In this time period, the unemployment rate of foreign-born females rose seven percentage points, while other vulnerable groups (e.g. foreign-born men, youth) in the Italian labor-market experienced a more dramatic rise in unemployment. This thesis will explain this relative job stability during this time period through an examination of Italy's elder care and immigration policies, and how the concentration of female migrants in the care industry has shielded them from the impacts of the economic crisis. In the end, the stability that foreign-born females have experienced is a positive, but does not eliminate the other vulnerabilities that female migrants face in their day-to-day lives. This thesis will argue that in order for the Italian state to prevent a long-term problem and maintain Italian society's preference for home care it will be necessary for Italy to create legislation that moves care work out of the informal sector. This will facilitate the integration of female migrant care workers into society and make the growing care sector more attractive to other groups within the labor market.
Multi-particle long-range rapidity correlations from fluctuation of the fireball longitudinal shape

description: We calculate the genuine long-range multi-particle rapidity correlation functions, $C_{n}(y_1,...,y_n)$ for $n=3,4,5,6$, originating from fluctuations of the fireball longitudinal shape. In these correlation functions any contribution from the short-range two-particle correlations, and in general up to $(n-1)$-particle in $C_n$, is suppressed. The information about the fluctuating fireball shape in rapidity is encoded in the cumulants of coefficients of the orthogonal polynomial expansion of particle distributions in rapidity.

An Evaluation of Provider Use of Secure Messaging
Creators: name: Nye, Christine

description: Patients value communication with their providers facilitated by electronic messaging. Further, communication via electronic messaging may help improve patient outcomes. The purpose of this study is to understand the relationships between providers’ perceptions of and their use of secure messaging, a form of electronic messaging, in practice. Literature suggests that providers may encounter barriers as they integrate electronic messaging into their practice and that variation exists in how providers incorporate its use into their daily workflow. Gaps exist in our understanding of how barriers and workflow variations impact providers’ use of electronic messaging and their subsequent effect on patient satisfaction and electronic messaging use. This study is a program evaluation and case comparison study of two outpatient clinics that use electronic messaging with their patients. Through analysis of surveys, secure messaging usage measures, direct observations, and semi-structured interviews, this study offers unique insight into contextual factors that impact electronic communication between patients and providers. The findings of this study suggest that effective use of team strategies and protocols may impact provider perceptions and use. Further research is necessary to understand how implementation of best practices suggested by this study may impact or transform use of secure messaging communication between patients and providers.

description: A new, extended nonlinear framework of the ordinary real analysis incorporating a novel concept of {\em duality structure} and its applications into various nonlinear dynamical problems is presented. The duality structure is an asymptotic property that should affect the late time asymptotic behaviour of a nonlinear dynamical system in a nontrivial way leading naturally to signatures generic to a complex system. We argue that the present formalism would offer a natural framework to understand the abundance of complex systems in natural, biological, financial and related problems. We show that the power law attenuation of a dispersive, lossy wave equation, conventionally deduced from fractional calculus techniques, could actually arise from the present asymptotic duality structure. Differentiability on a Cantor type fractal set is also formulated.

description: KERSTIN BRANDES / SIGRID ADORF: “By refusing to crystallise in any specific form”—Art, Visibility, Queer Theory: An Introduction This issue, entitled “By refusing to crystallise in any specific form”—Art, Visibility, Queer Theory, gathers contributions devoted to the question what queer theory on the one hand and (feminist) art history, visual culture, and media studies on the other have to offer one another. Although the question of visibility is central to both the politics of representation and the discourse of queer theory, which opposes normative definitions of the body and subjectivity, it is seldom tangibly related to the visual field. We hypothesise in this issue that the tools established by critical art history for analysing images within (their) specific contextualisations and areas of tension, such as the manifold interactions between historical images, viewers, and institutional frameworks, can crucially help extend queer theory’s productive engagement with visual culture. Thus, at stake is not only a critical discourse on images, but also the political scope of action that images can provide themselves with, that is, whether and how images can be regarded as agents in the sense of agency and how they might become (artistically) usable.
