description: We describe a new method to produce intensity stable, highly coherent, narrow-band x-ray pulses in self-seeded free electron (FEL) lasers. The approach uses an ultra-short electron beam to generate a single spike FEL pulse with a wide coherent bandwidth. The self-seeding monochromator then notches out a narrow spectral region of this pulse to be amplified by a long portion of electron beam to full saturation. In contrast to typical self-seeding where monochromatization of noisy SASE pulses leads to either large intensity fluctuations or multiple frequencies, we show that this method produces a stable, coherent FEL output pulse with statistical properties similar to a fully coherent optical laser.

description: We propose an explanation of several experimental features of transport phenomena in the normal state of high Tc cuprates in terms of a spin-charge gauge theory of the 2D t-J model. The calculated doping-temperature dependence for a number of physical quantities is found in qualitative agreement with data. In particular, we recover: in the ``pseudogap phase'' the metal-insulator crossover of the in-plane resistivity and of the NMR ``relaxation time'' and the insulating behavior of the out-of-plane resistivity; in the ``strange metal phase'' (at higher temperature or doping) the linear in T behavior of the above quantities; the appearance of maxima in the in-plane far-infrared conductivity in strongly underdoped and overdoped samples.

description: We propose an efficient and robust iterative solution to the multi-object matching problem. We first clarify serious limitations of current methods as well as the inappropriateness of the standard iteratively reweighted least squares procedure. In view of these limitations, we suggest a novel and more reliable iterative reweighting strategy that incorporates information from higher-order neighborhoods by exploiting the graph connection Laplacian. We demonstrate the superior performance of our procedure over state-of-the-art methods using both synthetic and real datasets.
Black Rings with Varying Charge Density

description: We find the general five-dimensional, supersymmetric black ring solutions in M-theory based upon a circular ring, but with arbitrary, fluctuating charge distributions around the ring. The solutions have three arbitrary charge distribution functions, but their asymptotic charges and angular momenta only depend upon the total charges on the ring. The arbitrary density fluctuations thus represent "hair." By varying the charge distributions one can continuously change the entropy of these black rings; to our knowledge this is the first solution in which the entropy depends on classical moduli. We also show that there is a family of solutions, with two arbitrary functions, for which the horizon remains rotationally invariant, and yet the complete solution breaks rotational symmetry. If the horizon area is set to zero then one obtains families of supertube solutions. We find that our general solutions are governed by three harmonic functions that may be thought of as classical excitations of a string. The horizon area provides a natural Lorentz metric on these excitations, and the constancy of the rotational invariance of the horizon imposes a set of Virasoro constraints.

We have demonstrated that the change in each parameter in response to a magnetic field near the ferromagnetic-paramagnetic phase transition temperature of the material correlates with the change in magnetic entropy. These findings allow us to interrelate these parameters and provide an alternative, effective approach for accessing the usefulness of magnetocaloric materials.

description:
In this study, a single zirconium carbide (ZrC) nanoneedle structure oriented in the <100> direction was fabricated by a dual-beam focused ion beam (FIB-SEM) system, and its field emission characteristics and emission current stability were evaluated. Benefiting from controlled fabrication with real-time observation, the ZrC nanoneedle has a smooth surface and a tip with a radius of curvature smaller than 20 nm and a length greater than 2 μm. Due to its low work function and well-controlled morphology, the ZrC nanoneedle emitter, positioned in a high-vacuum chamber, was able to generate a single and collimated electron beam with a current of 1.2 nA at a turn-on voltage of 210 V, and the current increased to 100 nA when the applied voltage reached 325 V. After the treatment of the nanoneedle tip, the field emission exhibited a stable emission for 150 min with a fluctuation of 1.4% and an emission current density as high as 1.4 × 1010 A m−2. This work presents an efficient and controllable method for fabricating nanostructures, and this method is applicable to the transition metal compound ZrC as a field emission emitter, demonstrating its potential as an electron source for electron-beam devices.

description: The objective of this study is to measure the impact of proposed Doha Round tariff reductions on the global dairy industry and dairy policy. We examine how proposed tariff reductions affect global trade and prices, and the implications for the European Union and the United States. Since international market conditions can vary, we examine the implications of liberalization under two sets of market conditions. The first corresponds to the year 2004 in which there was a global surplus of dairy products. In that year import protection ensured that U.S prices of dairy products were above world prices. The second corresponds to 2007, when dairy products globally were in short supply and U.S. domestic prices were at or below world prices. We show that proposed tariff reductions have different implications for dairy commodities depending on policy assumptions. For cheese and dry whole milk, tariff reductions reduce supplies and raise world prices due to reduced production in the EU. However, without a change in EU policies global butter prices would decline due an increase in EU supplies. Production shifts away from cheese into butter production, increasing the supply of butter on the world market. We conclude that with trade liberalization EU intervention prices or milk quotas would have to be reduced in order to counteract an increase in butter production and increased use of export restitution payments for that commodity.

description: The synthesis of complex oligosaccharides is desired for their potential as prebiotics, and their role in the pharmaceutical and food industry. Levansucrase (LS, EC 2.4.1.10), a fructosyl-transferase, can catalyze the synthesis of these compounds. LS acquires a fructosyl residue from a donor molecule and performs a non-Lenoir transfer to an acceptor molecule, via $β$-(2$\to$6)-glycosidic linkages. Genome mining was used to uncover new LS enzymes with increased transfructosylating activity and wider acceptor promiscuity, with an initial screening revealing five LS enzymes. The product profiles and activities of these enzymes were examined after their incubation with sucrose. Alternate acceptor molecules were also incubated with the enzymes to study their consumption. LSs from Gluconobacter oxydans and Novosphingobium aromaticivorans synthesized fructooligosaccharides (FOSs) with up to 13 units in length. Alignment of their amino acid sequences and substrate docking with homology models identified structural elements causing differences in their product spectra. Raffinose, over sucrose, was the preferred donor molecule for the LS from Vibrio natriegens, N. aromaticivorans, and Paraburkolderia graminis. The LSs examined were found to have wide acceptor promiscuity, utilizing monosaccharides, disaccharides, and two alcohols to a high degree.

description: The Common Agricultural Policy of the EU has been a dominant factor in the development of the Hungarian agricultural economy for several years; and it will continue to be in the years to come. CAP is in a state of continuous change; it is constantly being reformed and developed. In relation to this, the common budget of the enlarged European Union should cover the finances of the existing Community policies, and meet the criteria of enhancing competitiveness. To arrive at this balance is a great challenge for the EU. At the same time, maintaining a common financing policy in the long term is of special interest to Hungary. To maintain a suitable level of Community preference (import protection) is also important for us, because European requirements on food quality, environment and animal health are stricter than those prescribed by international partners. Our market must be defended from products appearing on the globalized market that are of uncertain origin, of poor quality and do not meet all food safety rules. When working on the further development of CAP or on the shaping of Hungarian agricultural policy, we have to reach a certain harmony, to realise the synergy of economic, environmental, social and rural development functions of agriculture.

description: Visual artists spend a substantial amount of time during studio processes to arrive at a Flow state naturally. This state is characterised by the experience of unparalleled presence, or a paramount reality defined by discernible focus and a lack of comprehension of time and space. This practice-led research project concerns studio explorations of distinct drawing and painting exercises, referred to as Zone-In exercises, which rapidly facilitate entering the creative zone and accelerating a creative Flow experience. Through these specific time-precise technical methods, the Flow state can be anticipated and predicted without having to wait to enter the zone after a substantial studio time commitment.
This doctoral research consists of a series of creative works representing 80% of the assessable outcome due to the studio outcomes being the seminal aspect of this research project. The weighting of the exegesis is set at 20% as theoretical support to the concerns produced in the studio outcomes. As such, the seminal focus has been placed on researching and demonstrating the respective innovations concerning the discovery, development, and application of the Zone-In exercises through establishing the Creative Flow Studio Model. Its unique practice-led methodology weaves together the three key concepts of ‘Flow’, ‘Process Art’ and ‘Anthroposophy’ within the visual arts disciplines of drawing and painting. This model enables the practising artist to deliberately enter the zone or Flow state to maximise studio time and effort for enhanced studio production. The research outcome integrates the Creative Flow Studio Model’s exercises with a Process Art-based practice and embodies a frame through which a sequence of artwork can be and is produced.

description:
Several challenges to validity have been identified with standard approaches used to measure “demand satisfied for modern methods of family planning.” This study explored construct validity of the widely used indicator for “demand satisfied” by comparing the standard definition to alternative definitions of the indicator highlighting dimensions of women’s own perceived demand, choice, and satisfaction. This cross-sectional study of women aged 15–49 years was conducted in Argentina (n = 1492), Ghana (n = 1600), and India (n = 1702) using a two-staged random sampling design. Women were directly asked about their: 1) demand, whether they wanted to use a contraceptive method to prevent pregnancy; 2) choice, whether they had autonomy in decision-making during their last family planning visit; and 3) satisfaction, whether they were satisfied with their method. The values of the standard and alternative indicators were compared. Convergent validity was assessed using logistic regression to explore the association between indicator definition and use of a preferred contraceptive method. In Argentina and India, the percentage of women with demand satisfied after incorporating constructs of demand, choice, and satisfaction was substantially lower than that obtained using the standard definition—a reduction of ~70% in Argentina and ~40% in India. Women who were categorized as having their “demand satisfied” for family planning according to the person-centered dimensions of the alternative indicator were significantly more likely to be using their preferred method of contraception in all three countries (OR: 7.7, 95% CI: 5.31–11.07 in Argentina, OR: 4.83, 95% CI: 2.27–10.27 in Ghana, and OR: 2.07 95% CI: 1.11–3.86 in India) compared to those whose demand was satisfied by only the standard indicator definition. Revising the definition of demand satisfied to reflect the principles of person-centered care offers an opportunity to improve construct validity by ensuring that global measurement efforts align with women’s reproductive rights.

Book theft and stock loss in academic libraries is certainly not a new problem.

Greater acknowledgement of the costs and effects that it causes must be made by institutions. This dissertation focuses on the key issues in this area, while undertaking a case study of the University of Leeds. This dissertation satisfied these aims by undertaking a large review of the relevant literature on the subject and by implementing practical research.

A number of key findings were made by this research: despite this being a problem that an organisation such as the University of Leeds is aware of, there is still a high level of theft and stock loss occurring at this institution; the implementation of guidelines for users, and a clear policy on how to deal with these losses may well help reduce them; library security devices are not infallible, and constant vigilance must be kept up, and ways of circumventing the devices must be counteracted or eliminated; non-return has not traditionally been thought of in the same terms as theft, yet the library loses a serious amount of stock each year.

The main conclusions this research found were that while there are many different approaches to tackling this problem, solutions must be effective for each organisation. By focusing the case study on one organisation, the unique qualities could be examined, while specific recommendations could be made for the University of Leeds.

description: With the increase of COVID-19 cases worldwide, an effective way is required to diagnose COVID-19 patients. The primary problem in diagnosing COVID-19 patients is the shortage and reliability of testing kits, due to the quick spread of the virus, medical practitioners are facing difficulty identifying the positive cases. The second real-world problem is to share the data among the hospitals globally while keeping in view the privacy concerns of the organizations. Building a collaborative model and preserving privacy are major concerns for training a global deep learning model. This paper proposes a framework that collects a small amount of data from different sources (various hospitals) and trains a global deep learning model using blockchain based federated learning. Blockchain technology authenticates the data and federated learning trains the model globally while preserving the privacy of the organization. First, we propose a data normalization technique that deals with the heterogeneity of data as the data is gathered from different hospitals having different kinds of CT scanners. Secondly, we use Capsule Network-based segmentation and classification to detect COVID-19 patients. Thirdly, we design a method that can collaboratively train a global model using blockchain technology with federated learning while preserving privacy. Additionally, we collected real-life COVID-19 patients data, which is, open to the research community. The proposed framework can utilize up-to-date data which improves the recognition of computed tomography (CT) images. Finally, our results demonstrate a better performance to detect COVID-19 patients.

description: Modeling ferroelectric materials from first principles is one of the successes of density-functional theory, and the driver of much development effort, requiring an accurate description of the electronic processes and the thermodynamic equilibrium that drive the spontaneous symmetry breaking and the emergence of macroscopic polarization. We demonstrate the development and application of an integrated machine learning model that describes on the same footing structural, energetic and functional properties of barium titanate ($\text{BaTiO}_3$), a prototypical ferroelectric. The model uses ab initio calculations as reference and achieves accurate yet inexpensive predictions of energy and polarization on time and length scales that are not accessible to direct ab initio modeling. These predictions allow us to assess the microscopic mechanism of the ferroelectric transition. The presence of an order-disorder transition for the Ti off-centered states is the main driver of the ferroelectric transition, even though the coupling between symmetry breaking and cell distortions determines the presence of intermediate, partly-ordered phases. Moreover, we thoroughly probe the static and dynamical behavior of $\text{BaTiO}_3$ across its phase diagram, without the need to introduce a coarse-grained description of the ferroelectric transition. Finally, we apply the polarization model to calculate dielectric response properties of the material in a fully ab initio manner, again reproducing the correct qualitative experimental behaviour.

description: Under current market circumstances and those predictable in the near future, further increasing agricultural production seems to be rather groundless. By utilising agro-ecological conditions more efficiently, one eighth of Hungary’s gasoline demand could be satisfied from maize production, without considerably decreasing current agricultural production for human and animal consumption. For realisation of biofuel programmes a relatively stable socio-economic environment is essential. There is considerable pressure on government from different stakeholders to shift the risks of large-scale investments to the state budget. In the long-run, under the conditions of a liberalised world market the feasibility of biofuel-programmes based on European raw materials, are highly questionable. To build up “shock-resistant” projects, well-founded, simulation-based risk analysis is essential.

description: Despite decades of efforts, robot navigation in a real scenario with volatility, uncertainty, complexity, and ambiguity (VUCA for short), remains a challenging topic. Inspired by the central nervous system (CNS), we propose a hierarchical multi-expert learning framework for autonomous navigation in a VUCA environment. With a heuristic exploration mechanism considering target location, path cost, and safety level, the upper layer performs simultaneous map exploration and route-planning to avoid trapping in a blind alley, similar to the cerebrum in the CNS. Using a local adaptive model fusing multiple discrepant strategies, the lower layer pursuits a balance between collision-avoidance and go-straight strategies, acting as the cerebellum in the CNS. We conduct simulation and real-world experiments on multiple platforms, including legged and wheeled robots. Experimental results demonstrate our algorithm outperforms the existing methods in terms of task achievement, time efficiency, and security.

Background Globally, low back pain (LBP) is responsible for disability among 60.1 million people. Health workers face a higher likelihood of being exposed to LBP compared to employees in the construction and manufacturing sectors. Data on LBP among hospital workers in Ghana are however limited. This study examined the prevalence, predisposing factors and turnover intention related to LBP among health workers in the Greater Accra region of Ghana.


Methods A multi-centred facility-based cross-sectional study was conducted in the Greater Accra region from January 30 –May 31, 2023. A multi-stage sampling technique was adopted, and the study participants were selected through proportion-to-size simple random sampling. STATA 15 software was used for analysis. Logistic regression analysis was used to determine the factors associated with LBP at a p < 0.05.


Results A survey was conducted among 607 health workers in 10 public and private hospitals. The prevalence of LBP was 81.6% [95% CI: (78.2%-84.6%)]. Advanced age [AOR = 1.07 (1.00, 1.16)], working for more than 5 days in a week [AOR = 8.14 (2.65, 25.02)], working overtime [AOR = 2.00 (1.16, 3.46)], rarely involved in transferring patients [AOR = 3.22 (1.08, 9.60)], most of the time involved in transferring patients [AOR = 6.95 (2.07, 23.26)], awkward posture during work [(AOR = 2.36 (1.31, 4.25)], perceived understaffing [(AOR = 1.84 (95% CI = 1.04–3.27)], sleep duration ≥ 8 [AOR = 0.54 (0.31, 0.97)] and sitting intermittently at work [AOR = 0.31 (0.12, 0.80)] were factors significantly associated with LBP. A substantial number, 123 (24.9%), occasionally had intention of leaving their jobs.


Conclusion The study revealed a high proportion of low back pain (LBP), and turnover intention attributed to LBP. Moreover, organizational and occupational factors were found to be significantly associated with LBP. These findings underscore the importance of targeted interventions aimed at reducing the burden of LBP within these specific areas.

Our research objective was to examine – taking the region’s economic and social circumstances into consideration – what conditions, consumer reception, and affinity is needed to gain competitive advantage with the involvement of renewable energy sources, and also to point out the characteristics of how the population currently uses energy, its mode and satisfaction level. During the examination of consumers’ familiarity level with renewable energy sources we observed the dominance of solar, hydro, and wind energy, nevertheless, their knowledge about these renewable energy sources was rather superficial. Concerning the main sources of knowledge on renewable energy sources we can state that the respondents showed a preference for traditional media, such as television, the press, and radio. It is apparent – as opposed to similar results from previous research – that the reference groups were the least significant influential sources of information in respect of the whole spectrum of respondents. The results of the attitude examination established the following facts: of the factors associated with renewable energy sources, environment protection, inexpensiveness, local energy production, and investment demand were most frequently mentioned. All this suggests that respondents are well aware of the cleanness of renewable energy sources and also that these sources will probably be cheaper than fossil fuels. Most respondents would typically give moral rather than financial support for the implementation of such an initiative.

description:
Background Preventing sexual assault in the United States (U.S.) military is essential to safeguard the overall well-being of military personnel and support the military to function in alignment with its intended mission and objectives. Valid instruments are needed to accurately and reliably evaluate programming effectiveness. The goal of this research was to psychometrically assess measures used to evaluate the Sexual Communication and Consent (SCC) program within the Air Force Basic Military Training (BMT) context.


Methods We evaluated four measures used to assess the SCC program implemented at Air Force BMT in 2019–2020: Date Rape Attitudes, Self-Efficacy to Resist Unwanted Advances, Risky and Protective Dating Behaviors, and Bystander Intentions. The analytic sample included 7,126 BMT trainees (74% male). We assessed structural validity with exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). We used full information maximum likelihood estimation with robust standard errors in Mplus. We refined each scale based on factor analysis results and assessed internal consistency reliability by computing Cronbach’s coefficient alpha for each scale in the overall sample, by sex, and by tailored SCC intervention group.


Results We identified a two-factor structure for the Date Rape Attitudes scale; subscale reliability was moderate within the overall sample and among males, though low among females. We found single-factor structures and excellent reliability for both the Self-Efficacy to Resist Unwanted Advances scale and the Bystander Intentions scale. The Dating Behaviors scale CFA did not confirm the two-factor solution suggested by the EFA, but subscale reliability was acceptable.


Conclusion This research fills a critical gap in the psychometric literature in military settings. Based on our findings, we recommend approaches for using the finalized scales in future evaluations of sexual assault prevention programming in the U.S. Air Force BMT setting.

description:
Universal coverage is defined by the World Health Organization as 1 long-lasting insecticidal net (LLIN) for 2 people in a household. While Uganda has been a leader in the distribution of LLINs, there are concerns regarding the longevity of LLINs. The main aim of this study was to address the LLIN coverage gap that emerges in the period after mass distribution campaigns through the implementation of a novel LLIN distribution strategy utilizing the existing community healthcare worker (CHW) infrastructure. We conducted a pilot feasibility study in two villages randomized to be the control or intervention. CHWs in both villages carried out their regular duties and calculated household eligibility to receive LLINs, classified as having a child under five positive for malaria and being below universal coverage. Only CHWs in the intervention village distributed LLINs to eligible households to reach universal coverage. Summary statistics were calculated for intervention implementation and malaria outcomes. Structured interviews were conducted with CHWs to assess burden and community acceptability of the intervention. Of the children evaluated by the CHWs, 102 of 169 (60.3%) and 112 of 171 (65.5%) were tested for malaria, of which 62 (60.7%) and 71 (63.3%) tested positive in the intervention and control villages, respectively. Only three households were at universal coverage. There was an increase from 4.0% to 6.5% of households meeting universal coverage in the intervention village, compared to a decrease from 7.8% to 1.8% in the control village after the follow-up period. There was an increase in the number of children under the age of 5 who slept under an LLIN the previous night from 15.7% to 31.6% in the intervention village compared to a decrease in the control village from 29.1% to 10.5%. No CHWs reported an increased burden from the intervention and all reported favorable opinions. Our pilot study demonstrates the feasibility and acceptability of targeted LLIN distributions leveraging the existing structure to supplement national distribution campaigns in Uganda. Overall, this work highlights the critical need for novel approaches to sustain LLIN coverage between distribution campaigns, particularly towards the end of the 3-year cycle.

description: The structure, linear stability, and dynamics of localized solutions to singularly perturbed reaction-diffusion equations has been the focus of numerous rigorous, asymptotic, and numerical studies in the last few decades. However, with a few exceptions, these studies have often assumed homogeneous boundary conditions. Motivated by the recent focus on the analysis of bulk-surface coupled problems we consider the effect of inhomogeneous Neumann boundary conditions for the activator in the singularly perturbed one-dimensional Gierer-Meinhardt reaction-diffusion system. We show that these boundary conditions necessitate the formation of spikes that concentrate in a boundary layer near the domain boundaries. Using the method of matched asymptotic expansions we construct boundary layer spikes and derive a new class of shifted Nonlocal Eigenvalue Problems for which we rigorously prove partial stability results. Moreover by using a combination of asymptotic, rigorous, and numerical methods we investigate the structure and linear stability of selected one- and two-spike patterns. In particular we find that inhomogeneous Neumann boundary conditions increase both the range of parameter values over which asymmetric two-spike patterns exist and are stable.

description: Many businesses in a wide range of industries are collecting and using large sets of text documents with information on their own operations and their commercial environments, and consequently they are becoming increasingly interested in tools like Automatic Concept Identification to help them manage their data files. This paper expands research into domain concepts and the processes of identifying them automatically from document collections with unrestricted yet narrowly defined domains. An automatic, scalable and consistent model of concept identification is proposed, integrating automatic text indexing techniques (for example stop-wording, stemming and phrase formation), a newly developed affinity measure, and Agglomerative Hierarchical Clustering techniques. To test the results of the proposed approach quantitatively, a system based on the proposed model has been developed and implemented, and three sensitivity studies have been conducted against three collections of technical white papers. This study contributes to the development of a word pair-wise affinity measure based on word co-occurrence, the distance between words being evaluated, and a variety of selection criteria and thresholds for index terms (e.g. Total Frequency and Document Frequency). This study's results concerning concept identification demonstrate that the proposed model generally delivers positive concept identification outcomes. The results of the sensitivity studies provide empirical evidence regarding the effects on concept identification outcomes generated by different index term selection thresholds, different sizes of co-occurrence windows, and different characteristics of document collections.

description: The sodium monoxide radical (NaO) is observed in night glow in the Earth's mesosphere and likely has astronomical importance. This study concerns the optical transitions within the ground X $^2Π$ state and to the very low-lying ($T_{\textrm e}\approx 2000$ cm$^{-1}$) excited A $^2Σ^+$ state. A line list consisting of rovibronic term values, allowed electric dipole transitions, Einstein coefficients, and partition functions for varying temperature are produced due to a variational solution of the coupled-channel Schrödinger equations using the program \Duo. MRCI \textit{ab initio} calculations characterising the potential energy curves of the both states, spin-orbit and $L$-uncoupling non-adiabatic matrix elements, as well as permanent and transition dipole moments were integral in formation of the final deperturbation model. \textit{Ab initio} potential energy curves are represented in the analytical Extended-Morse-Oscillator form and refined, along with the spin-orbit and $L$-uncoupling functions, by least-squares fitting to the available spectroscopic data. The input experimental data consisted of pure rotational transitions within the fine structure components of the X $^2Π$ state for $v''\in [0,3]$ vibrational levels as well as the rovibronic A $^2Σ^+(v'=0) \leftarrow$ X $^2Π(v''=0)$ transitions, both with limited coverage over rotational excitation. The lack of data detailing the vibrational structure of the X and A states prompts a request for further experimental study of higher excited levels which would provide a robust spectroscopic model. The NaO NaOUCMe line list is available via www.exomol.com and the CDS database.
