description: A new design strategy is introduced to address a persistent weakness with resonance thermally activated delayed fluorescence (R‐TADF) emitters to reduce aggregation‐caused quenching effects, which are identified as one of the key limiting factors. The emitter Mes3DiKTa shows an improved photoluminescence quantum yield of 80% compared to 75% for the reference DiKTa in 3.5 wt% 1,3‐bis(N‐carbazolyl)benzene. Importantly, emission from aggregates, even at high doping concentrations, is eliminated and aggregation‐caused quenching is strongly curtailed. For both molecules, triplets are almost quantitatively upconverted into singlets in electroluminescence, despite a significant (≈0.21 eV) singlet‐triplet energy gap (ΔEST), in line with correlated quantum‐chemical calculations, and a slow reverse intersystem crossing. It is speculated that the lattice stiffness responsible for the narrow fluorescence and phosphorescence emission spectra also protects the triplets against nonradiative decay. An improved maximum external quantum efficiencies (EQEmax) of 21.1% for Mes3DIKTa compared to the parent DiKTa (14.7%) and, importantly, reduced efficiency roll‐off compared to literature resonance TADF organic light‐emitting diodes (OLEDs), shows the promise of this design strategy for future design of R‐TADF emitters for OLED applications.

description: We consider the time-dependent Ginzburg-Landau model of superconductivity in the presence of an electric current flowing through a two-dimensional wire. We show that when the current is sufficiently strong the solution converges in the long-time limit to the normal state. We provide two types of upper bounds for the critical current where such global stability is achieved: by using the principal eigenvalue of the magnetic Laplacian associated with the normal magnetic field, and through the norm of the resolvent of the linearized steady-state operator. In the latter case we estimate the resolvent norm in large domains by the norms of approximate operators defined on the plane and the half-plane. We also obtain a lower bound, in large domains, for the above critical current by obtaining the current for which the normal state looses its local stability.

Antibacterial Properties And Characterisation Of Diamond And Graphite Thin Films And Coatings For Biomedical Applications

description: The rise of bacteria resistant to a wide spectrum of antibiotics has been a concern for researchers in the last decades. Several strategies to replace antibiotics were investigated such as silver or copper-based materials to name only the most promising antibacterial agents. However, bacteria evolve fast. Structural and genetic resistance abilities appeared before copper and silver drawbacks of being toxic to mammalian cells were overcome with research. Thus, it is critical to find alternatives with higher intrinsic biocompatibility and less chance for bacteria to develop resistance mechanisms against them. Carbon-based, and especially diamond-based materials are very promising regarding these properties. Their antibacterial abilities as surface-modified materials, drug carriers, and biocompatible materials were already demonstrated at different scales. However, the mechanisms of action of antibacterial diamonds are not understood yet. Hence, this PhD focused on understanding the influence of the carbon hybrids proportion in the diamond structure on their antibacterial properties. The results obtained with two model bacteria strains showed that the sp2/sp3 hybridised carbon ratio affected the antibacterial properties of diamond films. The higher the sp3 proportion, the better the antibacterial properties against both bacteria. The role of the spatial localisation of the electrons involved in sp3 hybridisation was discussed to explain these results. Surface structure of diamond films showed promising abilities to kill Gram-negative bacteria in the literature but failed against Gram-positive bacteria. This work demonstrated that adapting the size of the surface structures to the Gram-positive bacteria by tailoring the roughness also increased the surface free energy of the diamond films and displayed antibacterial properties against both Gram-positive and Gram-negative bacteria. Finally, the film deposition technique is also of prominent importance, and it modified several surface characteristics of the graphite films, explaining why CVD graphite coatings showed substantial antibacterial properties while PVD graphite coatings did not.

description: Understanding how different physical processes can shape the probability distribution function (pdf) of surface temperature, in particular the tails of the distribution, is essential for the attribution and projection of future extreme temperature events. In this study, the contribution of soil moisture-atmosphere interactions to surface temperature pdfs is investigated. Soil moisture represents a key variable in the coupling of the land and atmosphere, since it controls the partitioning of available energy between sensible and latent heat flux at the surface. Consequently, soil moisture variability driven by the atmosphere may feed back on near-surface climate, in particular temperature. In this study, two simulations of the current-generation Geophysical Fluid Dynamics Laboratory (GFDL) earth system model, with and without interactive soil moisture, are analyzed in order to assess how soil moisture dynamics impact the simulated climate. Comparison of these simulations shows that soil moisture dynamics enhance both temperature mean and variance over regional ’hotspots’ of land-atmosphere coupling. Moreover, higher-order distribution moments such as skewness and kurtosis are also significantly impacted, suggesting an asymmetric impact on the positive and negative extremes of the temperature pdf. Such changes are interpreted in the context of altered distributions of the surface turbulent and radiative fluxes. That the moments of the temperature distribution may respond differentially to soil moisture dynamics underscores the importance of analyzing moments beyond the mean and variance to characterize fully the interplay of soil moisture and near surface temperature. In addition, it is shown that soil moisture dynamics impacts daily temperature variability at different time scales over different regions in the model.

description: Occupational epidemiology has its roots in classical medicine. However, it became a quantitative discipline only in the 20th century, through the pioneering work of individuals such as Case, Lloyd, and Selikoff and organizations such as the Division of Occupational Health of the U.S. Public Health Service. Studies of chemical dye workers, bituminous coal miners, smelting workers, and uranium miners have been especially important sources of innovations in methodology and in development of logical reasoning leading to acceptance of causal relationships of occupational exposures that lead to respiratory diseases and cancer. The cooperation of labor unions, such as those of steel and asbestos workers, has often been a crucial factor in providing essential data.
Gravitational corrections to the scattering of scalar particles

description: We evaluated the scattering amplitude of neutral scalar particles at one-loop order in the context of effective field theory of quantum gravity in the presence of a cosmological constant. Our study suggests that quantum gravitational corrections induce an asymptotic freedom behavior to the $λϕ^4$ theory, for a positive cosmological constant. This result hints that a complete theory of quantum gravity can play an important role to avoid the issue of triviality in quantum field theory.

description: The solar granulation is known for a long time to be a surface manifestation of convection. Thanks to the current space-borne missions CoRoT and Kepler, it is now possible to observe in disk-integrated intensity the signature of this phenomena in a growing number of stars. The space-based photometric measurements show that the global brightness fluctuations and the lifetime associated with granulation obeys characteristic scaling relations. We thus aim at providing a simple theoretical modeling to reproduce these scaling relations and subsequently at inferring the physical properties of granulation properties across the HR diagram. We develop a simple 1D theoretical model that enable us to test any prescription concerning the time-correlation between granules. The input parameters of the model are extracted from 3D hydrodynamical models of the surface layers of stars, and the free parameters involved in the model are calibrated with solar observations. Two different prescriptions for representing the eddy time-correlation in the Fourier space are compared: a Lorentzian and an exponential form. Finally, we compare our theoretical prediction with a 3D radiative hydrodynamical (RHD) numerical modeling of stellar granulation (ab-initio approach). Provided that the free parameters are appropriately adjusted, our theoretical model satisfactorily reproduces the shape and the amplitude of the observed solar granulation spectrum. The best agreement is obtained with an exponential form. Furthermore, our theoretical model results in granulation spectra that consistently agree with the these calculated on the basis of the ab-initio approach with two 3D RHD models. Comparison between theoretical granulation spectra calculated with the present model and high precision photometry measurements of stellar granulation is undertaken in a companion paper.

description: Tricoordinate phosphorus compounds react with a wide variety of double bonds through addition reactions. The dipolar and cyclic products formed are important intermediates in organophosphorus chemistry. We investigated the reactivity between phosphorus triamide 1 and nitrosoarenes and 2-acylpyridines. For sterically congested substrates, the formation of σ5,λ5-phosphorus products is observed. DFT calculations indicate this product is formed through a concerted [4 + 1] mechanism. For less sterically congested substrates, products are observed arising from cleavage of the N = O or C = O bond with formation of a terminal P = O bond and aryl nitrene or carbene migration into a P–N bond of the phosphorus triamide core. DFT calculations are consistent with an initial [2 + 1] addition to phosphorus followed by formal carbene/nitrene migration in these cases.

description: Server Availability (SA) is an important measure of overall systems security. Important security systems rely on the availability of their hosting servers to deliver critical security services. Many of these servers offer management interface through web mainly using an Apache server. This paper investigates the increase of Server Availability by the use of Artificial Neural Networks (ANN) to predict software aging phenomenon. Several resource usage data is collected and analyzed on a typical long-running software system (a web server). A Multi-Layer Perceptron feed forward Artificial Neural Network was trained on an Apache web server data-set to predict future server resource exhaustion through uni-variate time series forecasting. The results were benchmarked against those obtained from non-parametric statistical techniques, parametric time series models and empirical modeling techniques reported in the literature.

description: We report the direct detection of two metastable H(2S) atoms coming from the dissociation of a single cold H_2 molecule, in coincidence measurements. The molecular dissociation was induced by electron impact in order to avoid limitations by the selection rules governing radiative transitions. Two detectors, placed close from the collision center, measure the neutral metastable H(2S) through a localized quenching process, which mixes the H(2S) state with the H(2P), leading to a Lyman-αdetection. Our data show the accomplishment of a coincidence measurement which proves for the first time the existence of the H(2S)-H(2S) dissociation channel.

description: The novel coronavirus SARS-Cov-2 continues to have adverse impacts on human health. Despite the volume of experiments performed and data available, its biology is not yet fully understood. Functional omics technologies such as high throughput sequencing and mass spectrometry allow users to capture large quantities of complex data. From these individual data modalities, it is possible to extract valuable information associated with a biological system under study, leading to new discoveries and a deeper knowledge of biology. However, combining these blocks of information can yield information that is not visible with a single data modality.

To better understand this virus, we take a multi-omics integrative view of the data, combining both proteomics and translatome data. This is in contrast to existing studies which mostly focus on a single aspect of functional omics data, primarily the genome. As a result of this fragmented view, valuable information may be masked. Using a latent variable approach, our integrative pipeline unifies proteome and translatome. We compared the features of interest contributing to each biological outcome across the individual data blocks and the integrated omics data. This revealed previously invisible and potentially medically relevant features for drug development.

description: Our fifth book in the International Research on School Leadership series focuses on the use of data in schools and districts as useful information for leadership and decision making. Schools are awash in data and information, from test scores, to grades, to discipline reports, and attendance as just a short list of student information sources (Bernhardt, 2004), while additional streams of data feed into schools and districts from teachers and parents as well as local, regional and national policy levels (Henig, 2012; Honig & Venkateswaran, 2012; Piety, 2013). To deal with the data, schools have implemented a variety of data practices, from data rooms, to data days, data walks, and data protocols (Mandinach & Gummer, 2013; Marsh, 2012). However, despite the flood of data, successful school leaders are leveraging an analysis of their school’s data as a means to bring about continuous improvement in an effort to improve instruction for all students (Boudett & Steele, 2007). Nevertheless, some drown, some swim, while others find success. Our goal in this book volume was to bring together a set of chapters by authors who examine successful data use as it relates to leadership and school improvement. In particular, the chapters in this volume consider important issues in this domain, including: - How do educational leaders use data to inform their practice? - What types of data and data analysis are most useful to successful school leaders? - To what extent are data driven and data informed practices helping school leaders positively change instructional practice? - In what ways does good data collection and analysis feed into successful continuous improvement and holistic systems thinking? - How have school leadership practices changed as more data and data analysis techniques have become available? - What are the major obstacles facing school leaders when using data for decision making and how do they overcome them?

description: With an overall collection and recycling rate of 74%, the material cycle for glass packaging is well established in the European Union. However, knowledge of the composition of the recycled glass cullet is necessary to avoid creeping accumulation of undesirable contaminants into the material cycle. Due to their toxic properties, this applies in particular for heavy metals, for example, lead. The state‐of‐the‐art technology for detection of lead in recycling glass sorting is X‐ray fluorescence (XRF). Due to lower regulatory demands, as well as increasingly economical hardware, laser‐based detection techniques, like Laser‐Induced Breakdown Spectroscopy (LIBS) may provide an alternate approach in industrial glass sorting to reach comparable detection limits and rates. In our work, CO2‐LIBS was investigated as an alternative tool for the determination of lead in glass cullet. Instead of usually utilized spectrometers, a combination of spectral filters and photodiode was employed to facilitate a fast detection rate. Glass samples with different lead content were investigated in two spectral ranges with respect to detection limits, detection speed, and accuracy. The results are compared to a commercial XRF‐sorting machine for glass cullet. It was found that comparable speeds and accuracies for lead detection in glasses can be reached.

We use exact diagonalization and high-temperature expansion up to order 10 to analyze the influence of the frustration strength J2/J1 and the spin quantum number s on the position and the height of the maximum of the susceptibility. The derived theoretical data can be used to get information on the ratio J2/J1 by comparing with susceptibility measurements on corresponding magnetic compounds.

description: Two pivotal problems in determining whether exposure to herbicides has caused disease in Vietnam veterans or their offspring are definition of which troops were exposed and extent of exposure. The DoD HERBS tape is the most complete publicly available record of herbicide spraying in Vietnam. It contains about 17,000 records consisting of coordinates of spray missions, dates, chemical agent, quantity and area sprayed, and mission purpose. We have developed a set of discrete and continuous indexes of probability of exposure to herbicides for individual veterans. These probability indexes are based on HERBS tape spray data and on locations and dates of service derived from a place-and-date matrix completed by the veteran. They can take into account a conservative estimate of environmental persistence of herbicide by using first-order exponential decay kinetics with an estimated half-life of dioxin. Mean values for the continuous exposure probability indexes were significantly greater among veterans judged to be exposed according to self-reported job titles and specific military experiences than among men judged unlikely to have been exposed. Probabilistic exposure indexes based on HERBS tape for classification of likely exposure to herbicides in South Vietnam during 1965-1971 appear to be well suited for comparative classification of veterans and hence for use in epidemiologic studies.

description: The teen movie Pretty in Pink presents a gendered dichotomy that exists between females as musical connoisseurs and males as emotional performers that is far from rare within the teen movie genre of the mid-1980's to early 2000's. These recurring tropes raise important questions about the teen movie genre and its use of popular music. How and why does the teen movie divide its musical scores along gendered lines? What do these musical differences tell us about the contrast between female and male adolescence? What is the significance of the "Rebel Girl" within the history of the teen movie, and how are we to interpret the teen boy who bursts into song onscreen? This article's goal is to dig more deeply into these questions by viewing the teen movies soundtrack through the lenses of gender identity, musical genre, and the cinematic conventions of popular song scoring.

However, preferential flow is rarely included in models simulating the hydrological response at the catchment scale. If it is considered, preferential flow parameters are typically determined at the plot scale and then transferred to larger‐scale simulations. Here, we successfully used the optimization algorithm DiffeRential Evolution Adaptive Metropolis (DREAM) to calibrate a 3D physics‐based dual‐permeability model directly at the catchment scale. In order to keep computational costs of the optimization routine at a reasonable level, we limited the number of parameters to be calibrated to the ones that had been shown before to be most influential for the simulation of discharge. We also calibrated parameters of the matrix domain and the macropore domain with a fixed parameter ratio between soil layers instead of calibrating every layer separately. These ratios reflected observed depth profiles of soil hydraulic properties at our study site. The dual‐permeability parameter sets identified during calibration were able to simulate observed discharge time series satisfactorily but did not outperform a calibrated single‐domain reference model scenario. Saturated hydraulic conductivities of the macropore domain were calibrated such that they became very similar to matrix saturated hydraulic conductivities, thereby effectively removing the effect of macropores. This suggests that the incorporation of vertical preferential flow as represented by the dual‐permeability approach was not relevant for reproducing the hydrometric response reasonably well in the studied catchment. We also tested the scale‐invariance of the calibrated dual‐permeability parameter sets by using the parameter sets performing best at catchment scale to simulate plot‐scale bromide depth profiles obtained from tracer irrigation experiments. This parameter transfer proved to be not successful, indicating that soil hydraulic parameters are scale‐variant, independent of the direction of parameter transfer.

Creators: name: ELLIPSE Consortium
Publisher: name: Zenodo
Year: 2023

description: Challenge: Ensuring the efficient use of natural resources and enhancing the valorisation and management of the increasing volume of waste generated thus reducing the volumes of landfilled waste, decreasing soil degradation, groundwater pollution and methane emissions.
Solution: ELLIPSE aims to address the valorisation of two heterogeneous waste streams, slaughterhouse (bellygrass) and paper & pulp sludge, to produce cost-efficient PHAs for agricultural and personal care applications, by the co-processing with other organic wastes such as glycerol from the biodiesel industry and sludge from the dairy industry, as well as recovering nutrients to produce bio-based fertilisers.
Pilots: The ELLIPSE project i) applies a 4 phases methodology to expand the opportunities for the valorisation of bio-waste across all stages and across all sectors and meet the requirements of the products for personal care and agriculture industries, ii) reach the scalability and consumer acceptance of the target products.
Outcomes:

Increased share of treated heterogeneous organic waste (OW) stream;
Increased market share of bio-based products from OW streams;
Increased acceptance of bio-based valorised solutions in the personal care and agriculture sectors;
Increase knowledge about the use of digital tools for modelling and data management;
To boost bio-based solutions production up to higher TRLs.

DNA adducts

description: Polycyclic aromatic hydrocarbon (PAH)-DNA adducts have been associated with breast cancer in several small studies. The authors' pooled analysis included 873 cases and 941 controls from a population-based case-control study. Competitive enzyme-linked immunosorbent assay in peripheral mononuclear cells was conducted in 2 rounds, and results were pooled on the basis of round-specific quantiles. The odds ratio for breast cancer was elevated in relation to detectable PAH-DNA adducts (1.29 as compared with nondetectable adduct levels; 95% confidence interval = 1.05, 1.58), but there was no apparent dose-response relationship with increasing quantiles. No consistent pattern emerged when the results were stratified by PAH sources (e.g., active cigarette smoking or PAH-containing foods), or when the cases were categorized by stage of disease or hormone receptor status. These data provide only modest support for an association between PAH-DNA adducts and breast cancer development.

description: We present late-time radio and X-ray observations of the nearby sub-energetic Gamma-Ray Burst (GRB)100316D associated with supernova (SN) 2010bh. Our broad-band analysis constrains the explosion properties of GRB100316D to be intermediate between highly relativistic, collimated GRBs and the spherical, ordinary hydrogen-stripped SNe. We find that ~10^49 erg is coupled to mildly-relativistic (Gamma=1.5-2), quasi-spherical ejecta, expanding into a medium previously shaped by the progenitor mass-loss with rate Mdot ~10^-5 Msun yr^-1 (for wind velocity v_w = 1000 km s^-1). The kinetic energy profile of the ejecta argues for the presence of a central engine and identifies GRB100316D as one of the weakest central-engine driven explosions detected to date. Emission from the central engine is responsible for an excess of soft X-ray radiation which dominates over the standard afterglow at late times (t>10 days). We connect this phenomenology with the birth of the most rapidly rotating magnetars. Alternatively, accretion onto a newly formed black hole might explain the excess of radiation. However, significant departure from the standard fall-back scenario is required.

description: The SSS-1P is a student small satellite program defined by the Asia-Pacific Space Cooperation Organization (APSCO) which is called the SSS program. The Attitude Determination and Control System (ADCS) has a critical rule in space missions. In fact, The ADCS can link the sensors data to actuators by many computational and complex algorithms such as Detumbling and Tumbling controller, Extended Kalman Filter (EKF), UKF, and etc.Since there is no physical access to the satellite for repairing, it is very important to decrease the possibility of failures and faults. Therefore, FDR is a crucial task in aerospace missions. In this work, KF estimation is the main tool to achieve this goal. To explain more, first, we model the dynamic and control of satellite then, we apply the Fault Detection and Recovery (FDR) algorithm into the ADCS subsystem. Also, Noise and disturbances are controlled using KF algorithms in sensors.In addition, in thesis Failure Mode Effects and Analysis (FMEA) and Fault Tree Analysis is done using standard tables of NASA and ECSS and professional discussions and meetings between engineers in the SSS project. Different Failure and Fault scenarios are considered and solutions to recover the system are given.Finally, the numerical results, simulations, and tables are analyzed and discussed. The validation is done for each section and more results are published in papers that prove the results are promising.

description: We report an earth‐abundant metal catalyzed double and single methylation of alcohols. A manganese catalyst, which operates at low catalyst loadings and short reaction times, mediates these reactions efficiently. A broad scope of primary and secondary alcohols including purely aliphatic examples and 1,2‐aminoalcohols can be methylated. In addition, alcohol methylation for the synthesis of pharmaceuticals has been demonstrated. The catalyst system tolerates many functional groups among them hydrogenation sensitive examples and upscaling is easily achieved. Mechanistic investigations are indicative of a borrowing hydrogen or hydrogen autotransfer mechanism involving a bimetallic K‐Mn catalyst. The catalyst accepts hydrogen as a proton and a hydride from alcohols efficiently and reacts with a chalcone via hydride transfer.
Emotional experiences in emergency ambulance services

description: Section one of this thesis is a meta-synthesis of qualitative literature exploring the emotional experiences of emergency ambulance personnel. Thorough searches of the literature were conducted in key databases, resulting in 16 studies being included in the synthesis. A meta-ethnography approach was followed, resulting in three overarching themes: moral distress, the emotional intensity of ambulance work and emotional regulation. The findings are considered in relation to related literature and theories. Several clinical implications and recommendations for future research are discussed. Section two is a qualitative study exploring the emotional experiences of emergency ambulance call handlers. Call handlers are the public’s initial point of contact to UK ambulance services and have critical information to obtain, in order to arrange an appropriate response. Twelve call handlers participated in semi-structured interviews, which were analysed using Interpretative Phenomenological Analysis. Three superordinate themes were identified: being more than a robot: “you’re not a robot and neither is the person on the end of the phone and neither is the patient”, belonging to a team: “we call each other the green family” and the unknown: “if you try and think about what’s going to happen next, you’d not be able to come to work”. The results are discussed in relation to theoretical perspectives, relevant literature, clinical implications and future research recommendations. Section three is a critical appraisal of the research process offering reflections on the ambiguity around the call handler role, the researcher’s previous experience, call handlers’ interest in the research and the potential relationship between emotional suppression and identifying or naming emotions. The complexities of managing the roles of a researcher and a practising clinician and the potential role for clinical psychologists in ambulance services are also discussed.
