description: Lanczos-type algorithms are well known for their inherent instability. They typically breakdown when relevant orthogonal polynomials do not exist. Current approaches to avoiding breakdown rely on jumping over the non-existent polynomials to resume computation. This jumping strategy may have to be used many times during the solution process. We suggest an alternative to jumping which consists in switching between different algorithms that have been generated using different recurrence relations between orthogonal polynomials. This approach can be implemented as three different strategies: ST1, ST2, and ST3. We shall briefly recall how Lanczos-type algorithms are derived. Four of the most prominent such algorithms namely $A_4$, $A_{12}$, $A_5/B_{10}$ and $A_5/B_8$ will be presented and then deployed in the switching framework. In this paper, only strategy ST2 will be investigated. Numerical results will be presented.
Positive Psychology and Counselling: A Clinical Mental Health Investigation Into Wellbeing in Qatar
Creators: name: Author, Unknown
Publisher: name: University of Lincoln
Year: 2023

description: The scope of the current thesis centred around two empirical projects and their underlying investigations. The first part aimed to validate the Qatari version of the Values In Action Inventory of Strengths (VIA-IS). The validation process involved a robust, translation task during which the VIA-IS (English) was translated into Arabic while preserving the linguistic and conceptual equivalence of all items. Next, exploratory and confirmatory factor analyses were conducted to reveal the underlying, character strengths dimensions. Findings confirmed the following four factors: Wisdom and knowledge strengths, humanity and justice strengths, embracing life strengths, and emotional strengths. The ultimate phase of the first project was related to examining the correlations between character strengths and indices of wellbeing as measured by the Satisfaction with Life Survey (SWLS) and Positive and Negative Affect Schedule (PANAS). The psychometric properties of the VIA-IS were also analysed and associations with measures of wellbeing were assessed. Significant correlations with life satisfaction were noted, and in terms of the relation between character strengths and affective components of wellbeing, all character strengths were found to be significantly and directly related to positive affect. Twenty out of the twenty-four character strengths were significantly related to negative affect. Open-mindedness, modesty, appreciation of beauty and excellence, and humor were not found to be significantly related to negative affect. The second project aimed at assessing the effectiveness of a strengths-based intervention in Counselling contexts. Participants completed the SWLS, the PANAS, and the Global Assessment of Character Strengths. Higher means for the satisfaction with life and positive affect and lower means for the negative affect were noted for participants in the individual intervention sessions as compared to the rest of participants. Participants in individual intervention sessions reported higher scores in satisfaction with life, positive affect, and lower scores in negative affect when compared with their counterparts in the group intervention sessions. Professionals who are interested in translating the VIA-IS into other languages might benefit from considering the methodology used in this research. The character strengths that were revealed in the Qatari context can be the groundwork for developing future research initiatives targeting various aspects of people’s mental health in various contexts. In addition, such findings might motivate other local and regional researchers, professionals, and academicians to begin exploring this topic in their own settings. Finally, the one-on-one counselling interventions could be prioritised for the purpose of enhancing citizens’ wellbeing.

description: In account of the statistical methods used in advanced manufacturing process optimization, multi-response optimization is one of the key areas of focus. Previously multi-response optimization problems were solved by past experiences and engineering judgment by many industries which lead to uncertainty in the decision making & and less confidence in getting optimized process parameters to produce robust products. For identifying the optimal process parameters for a manufacturing a robust product in which multiple CTQ (Critical-to-Quality) characteristics need to be achieved, a systematic statistical optimization approach is required. This paper presents one of the practical systematic approaches for multi-response optimization of advanced manufacturing processes. This statistical methodology uses Taguchi DoE (Design of Experiment) based approach to optimize the process parameters for individual CTQ followed by a multi-response optimization using composite desirability functions to achieve multiple CTQs.

description: Following the terminology developed in the Uniform California Earthquake Rupture Forecast, version 3 (UCERF3; e.g. Field et al. 2014), deformation models provide the specific locations, geometries and slip rates of the earthquake-producing faults explicitly modelled in the New Zealand National Seismic Hazard Model 2022 (NSHM). In this report, the derivation and characteristics of the upper-plate geologic deformation model is presented. So too is the derivation and characteristics of the two subduction interface models: the Hikurangi–Kermadec subduction interface deformation model and the Puysegur subduction interface deformation model. Details of the upper-plate geodetic deformation model are presented in a separate report (Johnson et al. 2022). (The authors)

description: A new one parameter lifetime distribution named, ‘Om distribution’ has been proposed and studied. Its various statistical properties including shapes for probability density, moments based measures, hazard rate function, mean residual life function, stochastic ordering, mean deviations, Bonferroni and Lorenz curves, distribution of order statistics, and stress-strength reliability have been discussed. Estimation of parameter has been discussed with the method of maximum likelihood. Applications of the distribution have been explained through two examples of real lifetime data from engineering and the goodness of fit found to be quite satisfactory over several one parameter lifetime distributions.

description: In this paper, we have presented economic production inventory model considering non-linear demand depanding on selling price. Here, all imperfect quality items are reworked after the regular production process and the reworked items are considered as similar as good quality items. Rework is important in those businesses where last product is expensive and raw materials are insuficient. Now, our objective is to find out the optimal ordering lot size, optimal selling price and shortage for which the profit of the model is maximum. A numerical example is presented to illustrate the validity of the model. Manageral implications has been presented in terms of the production and pricing of imperfect items.

description: The paper considers an accelerated test situation where the actual lifetimes of the items are not directly observable rather their status are known in the form of binary outcomes. By assuming two widely entertained models, namely the Weibull and the lognormal distributions, for the actual lifetimes, the paper provides full Bayesian analysis of the entertained models when both scale and shape parameters of the models are allowed to vary over the covariates involved in the study, thus giving rise to corresponding accelerated test models. The Bayes implementation is based on sample based approaches, namely the Metropolis algorithm and the Gibbs sampler using proper priors of the parameters where the prior elicitation is based on the expert testimonies. The situation involving missing items where actual status is also unknown is additionally entertained using the same modelling assumption. A comparison between the two entertained models is carried out using some standard Bayesian model comparison tools. Finally, numerical illustration is provided based on a given set of current status data and some relevant findings are reported.
Exploiting multiple outcomes in Bayesian principal stratification analysis with application to the evaluation of a job training program

description: The causal effect of a randomized job training program, the JOBS II study, on trainees' depression is evaluated. Principal stratification is used to deal with noncompliance to the assigned treatment. Due to the latent nature of the principal strata, strong structural assumptions are often invoked to identify principal causal effects. Alternatively, distributional assumptions may be invoked using a model-based approach. These often lead to weakly identified models with substantial regions of flatness in the posterior distribution of the causal effects. Information on multiple outcomes is routinely collected in practice, but is rarely used to improve inference. This article develops a Bayesian approach to exploit multivariate outcomes to sharpen inferences in weakly identified principal stratification models. We show that inference for the causal effect on depression is significantly improved by using the re-employment status as a secondary outcome in the JOBS II study. Simulation studies are also performed to illustrate the potential gains in the estimation of principal causal effects from jointly modeling more than one outcome. This approach can also be used to assess plausibility of structural assumptions and sensitivity to deviations from these structural assumptions. Two model checking procedures via posterior predictive checks are also discussed.

Investigating the Perceived Barriers to Women’s Rise to Leadership in Higher Education in Saudi Arabia
Creators: name: Author, Unknown
Publisher: name: University of Lincoln
Year: 2023

description: Abundant research has been conducted on barriers affecting women’s rise to leadership in Saudi Arabia. However, a number of developments have altered these barriers and this warrants the need for new research on the subject. This thesis is focused on one such development in the form of Saudi Vision 2030. Past research has identified a range of organisational, socio-cultural and personal barriers affecting women’s rise to leadership in Saudi higher education institutions (HEIs), several of which have been directly affected by the reforms announced and the steps taken by the Saudi government under Vision 2030. This research aimed to find out how Vision 2030 is likely to affect these barriers and consequently which barriers will continue to affect women leaders in Saudi HEIs. Such studies are likely to help policymakers in understanding how to continue their reform agendas to reach a desired future state. This mixed-methods research study began with a questionnaire survey of female academics in Saudi HEIs. Quantitative data were statistically analysed using SPSS. This was followed by semi-structured interviews with senior women professionals working in Saudi HEIs, providing qualitative data which were analysed using a thematic analysis approach. This research finds that a number of organisational, cultural and personal barriers affect women’s rise to a leadership position in Saudi HEIs. Furthermore, it finds that Vision 2030 has started to directly affect some of these barriers, leading to a widespread belief that women will face fewer such barriers in future. This research recommends continuing with the current reform agenda in order to significantly bridge the gender gap in leadership in Saudi HEIs. In particular, it recommends giving more recognition to women’s achievements in public, acknowledging these achievements in the same vein as men’s. Furthermore, it recommends providing women with equal development and growth opportunities. These are among the key steps that could significantly alter the status of women in leadership positions in Saudi HEIs.

description: Usually, systems and components are described as being in one of two modes, “on” or “off.” Such systems are described using binary structure functions. In multistate systems (MSS), components can be in more than two states—for example, there can be partially failed or partially operating modes. The system state can be described by continuously many values. A system that can have different task performance levels is named multi-state system (MSS). In this paper, we present a technique for solving a family of Continuous MSS reliability problems. A universal generating function (UGF) method is proposed for fast reliability estimation of continuous MSSs. The UGF method provides the ability to estimate relatively quickly different MSS reliability indices for series-parallel, parallel-series and bridge structures. It can be applied to MSS with different physical nature of system performance measure.

description: Mission-based subsystem reliability requirements are derived for a parent distributed network monitoring system operating under circumstances that differ from standard analytical constructs in a number of ways. First, the system comprises a hierarchy of elements of different functionalities individually adhering to distinct operational profiles. Second, some constituent elements only need to perform during relatively small and non-predetermined portions of the overall system mission accomplishment window. Third, failed elements can be restored or replaced in time to enable additional opportunities for satisfying mission needs.

description: The discovery of quasi-periodic oscillations (QPOs) in magnetar giant flares has opened up prospects for neutron star asteroseismology. The scarcity of giant flares makes a search for QPOs in the shorter, far more numerous bursts from Soft Gamma Repeaters (SGRs) desirable. In Huppenkothen et al (2013), we developed a Bayesian method for searching for QPOs in short magnetar bursts, taking into account the effects of the complicated burst structure, and have shown its feasibility on a small sample of bursts. Here, we apply the same method to a much larger sample from a burst storm of 286 bursts from SGR J1550-5418. We report a candidate signal at 260 Hz in a search of the individual bursts, which is fairly broad. We also find two QPOs at 93 Hz and one at 127 Hz, when averaging periodograms from a number of bursts in individual triggers, at frequencies close to QPOs previously observed in magnetar giant flares. Finally, for the first time, we explore the overall burst variability in the sample, and report a weak anti-correlation between the power-law index of the broadband model characterising aperiodic burst variability, and the burst duration: shorter bursts have steeper power law indices than longer bursts. This indicates that longer bursts vary over a broader range of time scales, and are not simply longer versions of the short bursts.

City/Campus Duality: Spatial Impact of University Campuses on Cities with reference to Lincoln, Worcester and Bath, UK
Creators: name: Author, Unknown
Publisher: name: University of Lincoln
Year: 2023

description: This research presents a critical investigation and analysis of the spatial configuration of three spatially similar cities and universities. Albeit, these cities are with different distributions of university campus accessibility and location in their cities. The research attempts to present a new approach to the conceptualization of relationship, between universities and cities, through an analytical investigation of the structure of urban space. This conception is the subject of investigation through a comparative analysis of urban structure in the University of Lincoln and Lincoln city, the University of Worcester and Worcester city, and the University of Bath and Bath city. Also, it shows that the spatial configuration of the city is influenced by the university, not only in terms of a various set of social elements, which include the urban structure such as the socio-economic environment, but also in terms of physical morphology. The aim of this study is to conduct an investigation into the spatial relationship between the university and the city from a theoretical viewpoint, which is informed by the notions of space and spatiality in an attempt to unveil the impact of university on the city, in terms of both physical and spatial relationship. This study utilises a mixed methods research to investigate and understand the relationship between universities and cities. These include a critical literature investigation, Space syntax analysis, Observation, interviews and socio-economic analysis. The finding indicated that the physical location of campuses has a direct impact of the relationship between universities and cites. However, there is no direct relationship between socio-economic impact and physical location of the campuses within cities. The results support that the city/campus duality is complex and it is based on a variety of indictors from socio-economic and socio-spatial points of view. Therefore, this relationship is bilateral. This thesis develops a new assessment tool to measure the quality of the relationship between university and city. Through the methodology and data analysis, this research provides guidelines for creating new insights into how cities and universities engage one another. The findings of this empirical study can be adopted as a compelling strategy for creating positive urban space within a campus utilising such critical investigation and syntax of campus-cities. The outcome of this study will form the basis for further development and planned growth of the universities and cities presented in this thesis.

description: "
As Doctor of Physical Therapy (DPT) students from the University of Nevada, Las Vegas, we completed a service-learning project to deliver a free evidence-based fall prevention program to senior residents of Nevada. “Stepping On” is a 7-week fall prevention program from the Wisconsin Institute for Healthy Aging that is designed for older adults who are at risk or fearful of falling or for those who want to increase their awareness of fall prevention strategies. The program includes learning balance and strengthening exercises, discussing fall prevention strategies, and collaborating with community partners and healthcare professionals. The first objective of this service-learning project was to offer the program to metropolitan and rural communities as well as through a virtual platform to improve access to this type of program. We also planned to measure the unique strengths and limitations of each platform through qualitative measures. This objective was measured through participant attendance, student critical analysis where we compared our experiences in leading each program, and feedback from participants, guest experts, and community partners. The project’s second objective was to advance our professional growth as DPT students, which was attained through written self-reflection. We each assessed our professional development in the context of the core values established by the American Physical Therapy Association (APTA).

There were initially 47 participants between the three platforms. By the end of the seventh week, 77% of the original participants remained. The highest percentage of completion was noted in the Pahrump platform, while the lowest percentage was amongst the Las Vegas platform. Through this project, we acquired leadership skills, improved our communication, adapted our teaching styles towards older adults, and recognized the importance of contributing to the communities’ specific needs. Out of the nine APTA core values, the three that were the most commonly reflected on were duty, collaboration, and compassion and caring. We additionally identified areas for improvement by analyzing our limitations, acknowledging constructive feedback from participants and guest partners, and recognizing areas for future work to enhance future programs. Overall, this service-learning project achieved its primary aims of improving access to an evidence-based fall prevention program in addition to facilitating our professional growth and development as DPT students.

description: Species boundaries delineating tropical sea anemones (Cnidaria, Actiniaria) of the zooxanthellate genus, Heteranthus Klunzinger, 1877, are unclear. There are currently two valid Heteranthus species: type species Heteranthus verruculatus Klunzinger, 1877, first reported from Koseir, Egypt, and H. insignis Carlgren, 1943, from Poulo Condore, Vietnam. In describing the latter from a single, poorly preserved specimen, zoologist Oskar Carlgren expressed apprehension with traits he had used to establish this species. Carlgren’s doubts persisted later in writing when he found a similar-looking sea anemone from the Great Barrier Reef. Crucial details to positively identify either species have since remained limited. Here, we re-diagnosed Heteranthus and re-described its type species based on observations from specimens we have obtained from Singapore and Pulau Ambon (Indonesia), and museum material collected elsewhere across the Indo-West Pacific region (n > 180). Supported by molecular phylogenetic evidence, the family Heteranthidae Carlgren, 1900 was reinstated and re-diagnosed. Heteranthus verruculatus is encountered in the lower intertidal region amongst seagrass, in rocky crevices, or coral rubble. It occurs as solitary individuals or in clonal clusters, well-camouflaged against the substratum. Individuals were observed to frequently propagate by longitudinal fission, resulting in a varied appearance. Type material of H. verruculatus and H. insignis were re-examined and as we found no differences between them, the two were synonymised. We inferred that Carlgren probably misinterpreted cnidae and histological data in defining H. insignis as a distinct species. This revision clarifies the taxonomy and geographic range of H. verruculatus, an Indo-West Pacific species that is found from the Red Sea to subtropical Australia and Hawaii.
Mass loss of massive stars near the Eddington luminosity by core neutrino emission shortly before their explosion

description: We present a novel mechanism to enhance the mass-loss rates of massive stars shortly before their explosion. The neutrino luminosities of the stellar core of massive stars become larger as they get closer to the time of the core collapse. As emitted neutrinos escape freely from the core, the core mass is significantly reduced when the neutrino luminosity is large. If a star is near the Eddington luminosity when the neutrino luminosity is large, the star can exceed the Eddington luminosity because of the core neutrino mass loss. We suggest that the stellar surface mass-loss rates due to the core neutrino emission can be higher than 1e-4 Msun/yr from ~ 1 year before the core collapse. The mass-loss rates can exceed 1e-2 Msun/yr in ~ 10 days before the core collapse. This mass-loss mechanism may be able to explain the enhanced mass loss observed in some supernova progenitors shortly before their explosion. Even if the star is not close enough to the Eddington luminosity to enhance mass loss, the star can still expand because of the reduced gravitational force. This mechanism can be activated in Wolf-Rayet stars and it can make hydrogen-poor, as well as hydrogen-rich, dense circumstellar media observed in some supernovae.

description: Some theories of dense molecular cloud formation involve dynamical environments driven by converging atomic flows or collisions between preexisting molecular clouds. The determination of the dynamics and physical conditions of the gas in clouds at the early stages of their evolution is essential to establish the dynamical imprints of such collisions, and to infer the processes involved in their formation. We present multi-transition 13CO and C18O maps toward the IRDC G035.39-00.33, believed to be at the earliest stages of evolution. The 13CO and C18O gas is distributed in three filaments (Filaments 1, 2 and 3), where the most massive cores are preferentially found at the intersecting regions between them. The filaments have a similar kinematic structure with smooth velocity gradients of ~0.4-0.8 km s-1 pc-1. Several scenarios are proposed to explain these gradients, including cloud rotation, gas accretion along the filaments, global gravitational collapse, and unresolved sub-filament structures. These results are complemented by HCO+, HNC, H13CO+ and HN13C single-pointing data to search for gas infall signatures. The 13CO and C18O gas motions are supersonic across G035.39-00.33, with the emission showing broader linewidths toward the edges of the IRDC. This could be due to energy dissipation at the densest regions in the cloud. The average H2 densities are ~5000-7000 cm-3, with Filaments 2 and 3 being denser and more massive than Filament 1. The C18O data unveils three regions with high CO depletion factors (f_D~5-12), similar to those found in massive starless cores.

description: This paper focuses on an essential task of the enhanced NodeB eNodeB element in LTE architecture, the Radio Resource Manager RRM, which aims to accept or reject requests for connection to the network based on some constraints and ensuring optimal distribution of radio resources between Users Equipments UEs. Its main functionalities include Admission Control AC and Packet Scheduling PS. This paper will center mainly on the PS part of the RRM task, which performs the radio resource allocation in both uplink and downlink directions. Several approaches and algorithms have been proposed in the literature to address this need ie : allocate resources efficiently, the diversity and multitude of algorithms is related to the factors considered for the optimal management of radio resource, specifically, the traffic type and the QoS Quality of Service requested by the UE. In this article, an art's state of the radio resource allocation strategies and a detailed study of several scheduling algorithms proposed for LTE (uplink and downlink) are made. Therefore, we offer our evaluation and criticism.

description:
Academy (AA) is a seven/eight-week program implemented by select University of Nevada, Las Vegas Doctorate of Physical Therapy (DPT) students to promote health and wellness at a Title I elementary school and help bridge the health education gap that underserved youth populations may be facing. We aimed to assess and improve the overall satisfaction of both the faculty members at the elementary school and the physical therapy students who participated in the program, while enhancing the health education of 5th grade students. Our aim was centered on stakeholders (elementary school administrators) and student mentors (DPT students) having the desire to continue implementing the AA program as a valuable health and wellness resource and to improve AA in the future. Lessons were centered around the musculoskeletal, cardiovascular, respiratory, gastrointestinal, and sensory nervous systems, as well as oral cavity and neuroanatomy. Each lesson had learning objectives for the children including introductory knowledge about each body system and different health care professions. UNLV DPT students focused on making the lessons engaging for elementary students by using active learning teaching methods (crafting art projects, exercising, recreational games, conducting science experiments, and hands-on participation). Stakeholders and student mentors were given a post-program survey to reflect on the different aspects of AA and areas of improvement. These were completed by 12 DPT students and 2 stakeholders (PE teacher and a teaching assistant). The survey results overall represented a positive response to AA. The qualitative and quantitative results allowed us to make suggestions for future UNLV DPT students to implement in future AA sessions to enhance the overall satisfaction.

We prove qualitatively sharp estimates of the corresponding potential kernels. Then we characterize those $1 \le p,q \le \infty$, for which the potential operators are $L^p-L^q$ bounded. These results are sharp analogues of the classical Hardy-Littlewood-Sobolev fractional integration theorem in the Laguerre and Dunkl-Laguerre settings.

description: Motivated by possible existence of string axions with ultralight masses, we study gravitational radiation from an axion cloud around a rotating black hole (BH). The axion cloud extracts the rotation energy of the BH by superradiant instability, while it loses energy through the emission of gravitational waves (GWs). In this paper, GWs are treated as perturbations on a fixed background spacetime to derive the energy emission rate. We give an analytic approximate formula for the case where axion's Compton wavelength is much larger than the BH radius, and then, present numerical results without approximation. The energy loss rate of the axion cloud through the GW emission turns out to be smaller than the energy gain rate of the axion cloud by superradiant instability until nonlinear self-interactions of axions become important. In particular, an axion bosenova must happen at the last stage of superradiant instability.

description: We present the first high resolution spectroscopic observations of one red giant star in the ultra-faint dwarf galaxy Segue 2, which has the lowest total mass (including dark matter) estimated for any known galaxy. These observations were made using the MIKE spectrograph on the Magellan II Telescope at Las Campanas Observatory. We perform a standard abundance analysis of this star, SDSS J021933.13+200830.2, and present abundances of 21 species of 18 elements as well as upper limits for 25 additional species. We derive [Fe/H] = -2.9, in excellent agreement with previous estimates from medium resolution spectroscopy. Our main result is that this star bears the chemical signatures commonly found in field stars of similar metallicity. The heavy elements produced by neutron-capture reactions are present, but they are deficient at levels characteristic of stars in other ultra-faint dwarf galaxies and a few luminous dwarf galaxies. The otherwise normal abundance patterns suggest that the gas from which this star formed was enriched by metals from multiple Type II supernovae reflecting a relatively well-sampled IMF. This adds to the growing body of evidence indicating that Segue 2 may have been substantially more massive in the past.

description: We consider recent work linking majorization and trumping, two partial orders that have proven useful with respect to the entanglement transformation problem in quantum information, with general Dirichlet polynomials, Mellin transforms, and completely monotone sequences. We extend a basic majorization result to the more physically realistic infinite-dimensional setting through the use of generalized Dirichlet series and Riemann-Stieltjes integrals.

Fault-tolerant conversion between the Steane and Reed-Muller quantum codes

description: Steane's 7-qubit quantum error-correcting code admits a set of fault-tolerant gates that generate the Clifford group, which in itself is not universal for quantum computation. The 15-qubit Reed-Muller code also does not admit a universal fault-tolerant gate set but possesses fault-tolerant T and control-control-Z gates. Combined with the Clifford group, either of these two gates generate a universal set. Here, we combine these two features by demonstrating how to fault-tolerantly convert between these two codes, providing a new method to realize universal fault-tolerant quantum computation. One interpretation of our result is that both codes correspond to the same subsystem code in different gauges. Our scheme extends to the entire family of quantum Reed-Muller codes.

Matching Emotions Across Visual and Auditory Modalities in Children with Autism
Creators: name: Author, Unknown
Publisher: name: University of Lincoln
Year: 2023

description: Previous literature suggests that children with autism display a difference in recognising emotions, typically showing a unique pattern of processing, which can appear as a deficit in emotion recognition ability. These studies tend to be unimodal, which makes conclusions as to the location of these differences difficult. The current study presents an attempt to determine where autistic people differ in the emotion recognition process, and whether a higher-level processing difference, or many distinct modality-specific lower-level differences are responsible for modulating performance. It also aims to unpack what other elements could influence performance, such as age and gender. This was tested by assessing the performance of autistic (N = 29) and typically developing children (N = 74) to label and match emotions presented both visually and audibly. The autistic group showed no general impairment for the tasks, but each task had unique, significant emotion specific differences, these cannot be explained fully by any single theory currently, suggesting multiple factors play a small but distinct role in the effect of autism on emotional recognition. Furthermore, the autistic group demonstrated a strong, significant correlation for task performance across modalities which was not found in the typically developing group, suggesting the presence of a higher-level processing difference, possibly caused by changes to the amygdala. No gender differences were observed in any task or group, but a nonsignificant effect of age was observed in the multimodal matching task only, suggesting a developmental delay. Future suggestions of research, limitations of the methodology, and the implications of these findings are discussed.
Exact value of the correlation factor for the divacancy mechanism in FCC crystals: the end of a long quest

description: The correlation factor for diffusion by the divacancy mechanism in an FCC lattice has been the target of a long quest. Amounting to 0.54 at the beginning, its value was progressively decreased down to 0.4582 with a confidence interval of 0.0005. The limitations of previous studies came from the matrix method at work which confined the defect trajectories to a volume of finite extension around the tracer atom, or, more basically, from the availability of computing time for the numerical simulations. The present study determines the exact value thanks to a double Laplace-Fourier transform of the transport equation, which takes into account all the divacancy trajectories without any limitation of their lengths. The exact value is lower than all the preceding evaluations, but falls within the confidence interval which was estimated from the best evaluations based on simulations. One interesting byproduct of our analytical approach is the proof of the equality t11=t22.

description: In images with low contrast-to-noise ratio (CNR), the information gain from the observed pixel values can be insufficient to distinguish foreground objects. A Bayesian approach to this problem is to incorporate prior information about the objects into a statistical model. This paper introduces a method for representing spatial prior information as an external field in a hidden Potts model of the image lattice. The prior distribution of the latent pixel labels is a mixture of Gaussian fields, centred on the positions of the objects at a previous point in time. This model is particularly applicable in longitudinal imaging studies, where the manual segmentation of one image can be used as a prior for automatic segmentation of subsequent images. The model is demonstrated by application to cone-beam computed tomography (CT), an imaging modality that exhibits distortions in pixel values due to X-ray scatter. The external field prior results in a substantial improvement in segmentation accuracy, reducing the mean pixel misclassification rate on our test images from 87% to 6%.

description: "The Future of Supersonic Flight"FEEG1020 Technical Essay (Part 1 Formative)

Supersonic travel is a ubiquitous mode of transport that has been widely recognised since the 1960s. Humans rely on supersonic flights to traverse across vast landmasses in an efficient time. Not until recently, the future of aviation has been rendered uncertain due to the unforeseen pandemic. Nevertheless, this denotes a transformative period of the aviation industry, with the emergence of disruptive technologies and pivotal design features, in lieu of grounded flights. In this essay, we will primarily discuss about the background and renaissance of commercial supersonic transport, its prevailing challenges, proposed novel solutions and technologies, and the future sustainability.
