Total scatter factor for clinically relevant fields in stereotactic radiosurgery dosimetry
Creators: name: Ameur, Zakia
Publisher: name: RMIT University
Year: 2024

description: In SRS, the actual planned clinical m3 mMLC fields are irregular and shaped by the mMLC leaves; they are more complex than those set for the commissioning data measurements and hence, the scatter contributions may be different to those pertaining to the regular fields.

In this study, RDFs were measured using a range of m3 mMLC (BrainLAB, Heimstetten, Germany) fields of different shapes and same equivalent square areas in order to validate this notion of equivalency between irregular and square fields. The range of the m3 mMLC fields includes the square mMLC fields. Given that RDFs are measured and defined for a set of jaws-mMLC fields, their variation with respect to jaws was also investigated, including its impact on the MU accuracy: for the same m3 mMLC setting, different jaws openings were tested to notice the effects of jaws only on RDF. Thus, measurements of RDF were performed and examined for ten irregular m3 mMLC fields of 12.3 x 12.3 to 51.0 x 51.0 mm2 combined with fields set by the jaws of 2.5 x 2.5 to 9.8 x 9.8 cm2. Using the BrainSCAN TPS, iPlan, each m3 mMLC field in the lowest range was generated under three different shapes of the same area. The jaws fields were then set from the Linac console. The detectors used for dose measurements were IC3, IC13, stereotactic diode (SFD) and the PRESAGE dosimeter. Calculations of RDF using iPlan were also performed and compared to each other for different shapes and same equivalent square of m3 mMLC fields.

Examined in this research were the following questions: 1) the validity of the equivalent square concept, 2) the validity of irregular m3 mMLC fields in the commissioning of BrainSCAN TPS, and, 3) the safety of the jaws in the static position throughout a treatment plan and delivery.

It was found that RDF were responsive to mMLC shapes even if the areas are the same. The response was different from one detector to another due to the size and type of detector. The response of RDF for different mMLC shapes was also more pronounced for the smallest range of the fields. Thus, the equivalent square concept is more valid for the larger mMLC fields.

Also, the results have shown that RDFs are responsive to jaws opening only in the smallest mMLC fields: it is more practical to keep the jaws at the same position during a given treatment plan and delivery for that range of mMLC fields, as this allows reducing the mechanical uncertainty related to the movements of the jaws particularly when dealing with many treatment fields.
Collaboration and the use of online collaborative toolsets in the project management environment
Creators: name: Harley, James
Publisher: name: RMIT University
Year: 2024

description: The research aims to develop an understanding of the extent to which collaboration occurs through the use of online technologies in the project management environment. Given the breadth of the technological landscape, this research focuses on the use of online collaborative toolsets (OCTs).

The research investigates six Project Management Environments (PMEs) and their use of OCTs, and uses a Collaboration scale developed specifically to measure the level of collaboration existing within each PME. The Collaboration scale presents collaboration not as a single entity, but as a scale ranging from low to high across six elements. Central to this theory is that for collaboration to exist, all elements must rate highly against the scale. The research argues that although all collaborative elements are found within a PME, it is the level of each element that determines the degree to which collaboration is occurring.

A case study approach incorporated three broad strategies to collect data. The first strategy included a Likert questionnaire using the Dichotomous scale, which was administered to collect data on the operations of the individual projects. The second strategy included interviews that asked the project manager of each case specific questions regarding the PME. The third strategy involved desk research to scan for literature and web artefacts.

The conclusions drawn from this research are:

1. OCTs can contain a variety of features, several of which are common amongst all. The research identified common requirements and use of the OCTs within the cases. 2. Although OCTs are capable of facilitating a high level of collaboration, Project Managers do not use OCTs for this purpose. The different project environments reviewed are not necessarily collaborative, nor do they use OCTs to assist with collaborative exercises. 3. OCTs are used predominantly for cooperation and coordinating activities within the PME. 4. Collaboration in the PMEs reviewed exists in degrees, at times being identified with cooperative functions, and at other times coordinating functions. 5. The findings demonstrate a pattern of collaboration, which is consistent across all cases. This pattern demonstrates a variation in the collaborative elements across the PME, and indicates a priority that may exist in regard to how these elements are prescribed within the actual project environment.

description: We theoretically study the impact of light-driven structural changes via nonlinear phononics on the magnetic order of untwisted bilayer van der Waals materials. We consider an illustrative example of the AA-stacked bilayer honeycomb lattice and show that high-intensity light in resonance with selected phonons induces large amplitude phonon displacements that modify the magnetic Hamiltonian of the system. We performed a group theory analysis to identify the vibrational modes of the honeycomb bilayer and the nonlinear couplings among them in the strongly driven regime. We find that the structural changes in the strongly driven regime lower the symmetry relative to the equilibrium lattice and produce changes in the magnetic interactions between the local moments. In particular, the lattice symmetry changes permit a non-zero interlayer Dzyaloshinskii-Moriya interaction that induces a magnetic state with canted local moments. Using a spin-wave analysis about the new magnetic configuration we study the corresponding changes in the magnon spectrum and identify a protocol for engineering topological band transitions using a combination of nonlinear phononics and an external magnetic field. Our work suggests a strategy to induce and control interlayer Dyzaloshinskii-Moriya interactions in a class of layered van der Waals materials, the effect of which is to modify the magnetic ground state, magnon dispersions, and related band geometric properties, including topological invariants.
Combination of searches for singly produced vector-like top quarks in pp collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

description: A combination of searches for the single production of vector-like top quarks ($T$) is presented. These analyses are based on proton$-$proton collisions at $\sqrt{s}=13$ TeV recorded in 2015$-$2018 with the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 139 fb$^{-1}$. The $T$-quark decay modes considered in this combination are into a top quark and either a Standard Model Higgs boson or a $Z$ boson ($T \to Ht$ and $T \to Zt$). The individual searches used in the combination are differentiated by the number of leptons ($e$, $μ$) in the final state. The observed data are found to be in good agreement with the Standard Model background prediction. Interpretations are provided for a range of masses and couplings of the vector-like top quark for benchmark models and generalized representations in terms of 95% confidence level limits. For a benchmark signal prediction of a vector-like top quark SU2 singlet with electroweak coupling, $κ$, of 0.5, masses below 2.1 TeV are excluded, resulting in the most restrictive limits to date.

description: Constituent quarks in a nucleon are the essential elements in the standard ``quark model" associated with the electric charge, spin, mass, and baryon number of a nucleon. Quantum Chromodynamics (QCD) describes nucleon as a composite object containing current quarks (valence quarks and sea (anti-)quarks) and gluons. These subatomic elements and their interactions are known to contribute in complex ways to the overall nucleon spin and mass. In the early development of QCD theory in the 1970s, an alternative hypothesis postulated that the baryon number might manifest itself through a non-perturbative configuration of gluon fields forming a Y-shaped topology known as the gluon junction. In this work, we propose to test such hypothesis by measuring (i) the Regge intercept of the net-baryon distributions for $e$+($p$)Au collisions, (ii) baryon and charge transport in the isobaric ratio between $e$+Ru and $e$+Zr collisions, and (iii) target flavor dependence of proton and antiproton yields at large rapidity, transported from the hydrogen and deuterium targets in $e+p$(d) collisions. Our study indicates that these measurements at the EIC can help determine what carries the baryon number.

On e-pseudovarieties of finite regular semigroups
Creators: name: Rodgers, David
Publisher: name: RMIT University
Year: 2024

description: An e-pseudovariety is a class of finite regular semigroups closed under the taking of homomorphic images, regular subsemigroups and finite direct products. Chapter One consists of a survey of those results from algebraic semigroup theory, universal algebra and lattice theory which are used in the following two chapters. In Chapter Two, a theory of generalised existence varieties is developed. A generalised existence variety is a class of regular semigroups closed under the taking of homomorphic images, regular subsemigroups, finite direct products and arbitrary powers. Equivalently, a generalised e-variety is the union of a directed family of existence varieties. It is demonstrated that a class of finite regular semigroups is an e-pseudovariety if and only if the class consists only of the finite members of some generalised existence variety. The relationship between certain lat tices of e-pseudovarieties and generalised existence varieties is explored and a useful complete surjective lattice homomorphism is found. A study of complete congruences on lattices of existence varieties and e-pseudovarieties forms Chapter Three. In particular it is shown that a certain meet congruence, whose description is relatively simple, can be extended to yield a complete congruence on a lattice of e-pseudovarieties of finite regular semigroups. Ultimately, theorems describing the method of construction of all complete congruences of lattices of e-pseudovarieties whose members are finite E-solid or locally inverse regular semigroups are proved.

description: We present a multivariate functional mixed effects model for kinematic data from a large number of recreational runners. The runners' sagittal plane hip and knee angles are modelled jointly as a bivariate function with random effects functions used to account for the dependence among measurements from either side of the body. The model is fitted by first applying multivariate functional principal component analysis (mv-FPCA) and then modelling the mv-FPCA scores using scalar linear mixed effects models. Simulation and bootstrap approaches are introduced to construct simultaneous confidence bands for the fixed effects functions, and covariance functions are reconstructed to summarise the variability structure in the data and thoroughly investigate the suitability of the proposed model. In our scientific application, we observe a statistically significant effect of running speed on both the hip and knee angles. We also observe strong within-subject correlations, reflecting the highly idiosyncratic nature of running technique. Our approach is more generally applicable to modelling multiple streams of smooth kinematic or kinetic data measured repeatedly for multiple subjects in complex experimental designs.

Strategies for the sustainable redevelopment of residential buildings in Ulaanbaatar, Mongolia
Creators: name: Demberel, Enkhbaatar
Publisher: name: RMIT University
Year: 2024

description: The current condition of central Ulaanbaatar’s residential buildings and their associated infrastructure is in a critical state. It is important to study the current urban renewal process in Ulaanbaatar city, with a focus on solving recognized practical problems that arose from the necessity to improve a city centre neighbourhood. This study investigated how the redevelopment process of residential buildings in Ulaanbaatar city, Mongolia can be implemented in a sustainable way. It explored potential issues associated with residential redevelopment; analysis and integration of the research findings provides a framework for sustainable residential redevelopment.

A combined quantitative and qualitative research approach was used in this study. The researcher conducted a questionnaire survey to residents living in Ulaanbaatar and interviewed stakeholders and government authorities, to obtain a better understanding of potential problems which may influence redevelopment.

The survey of residents in dilapidated buildings established the nature of resident’s opinions of urban renewal and identified the condition of their buildings. It showed that they had strong concerns about whether redevelopment involving new multi-storey redevelopments built on site of their current residences is appropriate for the area and how it might influence their interest. The interviews with building professionals and local community representatives helped to ascertain issues affecting the refurbishment or redevelopment of dilapidated residential buildings. Discussions with personnel from relevant government agencies produced a deeper understanding of current urban renewal policy in Ulaanbaatar city, existing and prospective issues for urban renewal, and generated suggestions to deal with them.

The survey findings were aligned with the triple bottom line principles of sustainability and further categorized into different phases of a project life cycle, based on which a framework was developed to support the sustainable residential redevelopment. The framework integrated critical factors and issues likely to affect the residential redevelopment in the different phases of a project. At the end of the study the framework was validated through a questionnaire survey among urban development experts to determine whether a framework reasonably fulfils its intended use. It is expected that the framework will help to deal with existing issues and avoid potential problems associated with residential redevelopment in Ulaanbaatar city. Also, the study will contribute to the general field of urban renewal studies.

description: In the context of non-standard cosmologies, an early matter-dominated (EMD) era can significantly alter the conventional dark matter (DM) genesis. In this work, we reexamine the impact of an EMD on the weakly- and feebly-interacting massive particle (WIMP and FIMP) paradigms. EMD eras significantly modify the genesis of DM because of the change in the Hubble expansion rate and the injection of entropy. The WIMP paradigm can be realized with couplings much smaller than in the standard cosmological scenario, whereas much larger couplings are required in the FIMP case. Using the singlet-scalar DM model as a case study, we show that these results can lead to a continuous transition between the WIMP and FIMP scenarios, with results that are also applicable to other DM models. This broadens the parameter space consistent with observed DM levels and suggests that even elusive FIMP scenarios may be within the reach of future experimental searches.

Multizone wideband sound field reproduction
Creators: name: Radmanesh, Nasim
Publisher: name: RMIT University
Year: 2024

description: This thesis deals with the problem of multizone wideband sound field reproduction using an array of loudspeakers. A pressure matching approach is researched to control the sound field within the zones through the calculation of loudspeaker weights. The loudspeaker weights are computed first using a regularized least-squares (LS) approach and then a least-absolute shrinkage and selection operator (Lasso). It is demonstrated that the single-stage LS technique outperforms the single-stage Lasso in multizone wideband sound field reproduction, while the single-stage Lasso enables the judicious placement of loudspeakers. To improve the multizone sound reproduction performance of wideband sources using a limited number of loudspeakers, it is assumed that the virtual sources are fixed in positions. A new two-stage Lasso-LS pressure matching approach is then proposed to optimize both the loudspeaker locations and weights. In the first stage, a Lasso algorithm is used to select the loudspeakers' positions for all sources and frequency bands. A second stage then optimizes reproduction using all selected loudspeakers on the basis of a regularized LS algorithm. The results show that a horizontal array of limited number of loudspeakers (e.g. 52) can be used to effectively create personal audio spaces for multiple users of variable heights. The proposed method is then extended to a nested Lasso-LS method which employs harmonic nested arrays in the first stage Lasso to reduce the computational complexity. Effectively, the nested arrays provide a priori knowledge of prospective loudspeaker locations based on the frequency bands of interest. The final loudspeaker locations and weightings are then estimated during the two-stage Lasso-LS optimization.

description: Cardiac T1 mapping is a valuable quantitative MRI technique for diagnosing diffuse myocardial diseases. Traditional methods, relying on breath-hold sequences and cardiac triggering based on an ECG signal, face challenges with patient compliance, limiting their effectiveness. Image registration can enable motion-robust cardiac T1 mapping, but inherent intensity differences between time points pose a challenge. We present MBSS-T1, a subject-specific self-supervised model for motion correction in cardiac T1 mapping. Physical constraints, implemented through a loss function comparing synthesized and motion-corrected images, enforce signal decay behavior, while anatomical constraints, applied via a Dice loss, ensure realistic deformations. The unique combination of these constraints results in motion-robust cardiac T1 mapping along the longitudinal relaxation axis. In a 5-fold experiment on a public dataset of 210 patients (STONE sequence) and an internal dataset of 19 patients (MOLLI sequence), MBSS-T1 outperformed baseline deep-learning registration methods. It achieved superior model fitting quality ($R^2$: 0.975 vs. 0.941, 0.946 for STONE; 0.987 vs. 0.982, 0.965 for MOLLI free-breathing; 0.994 vs. 0.993, 0.991 for MOLLI breath-hold), anatomical alignment (Dice: 0.89 vs. 0.84, 0.88 for STONE; 0.963 vs. 0.919, 0.851 for MOLLI free-breathing; 0.954 vs. 0.924, 0.871 for MOLLI breath-hold), and visual quality (4.33 vs. 3.38, 3.66 for STONE; 4.1 vs. 3.5, 3.28 for MOLLI free-breathing; 3.79 vs. 3.15, 2.84 for MOLLI breath-hold). MBSS-T1 enables motion-robust T1 mapping for broader patient populations, overcoming challenges such as suboptimal compliance, and facilitates free-breathing cardiac T1 mapping without requiring large annotated datasets.

description: This paper proposes a self-learning method to incrementally train (fine-tune) a personalized Keyword Spotting (KWS) model after the deployment on ultra-low power smart audio sensors. We address the fundamental problem of the absence of labeled training data by assigning pseudo-labels to the new recorded audio frames based on a similarity score with respect to few user recordings. By experimenting with multiple KWS models with a number of parameters up to 0.5M on two public datasets, we show an accuracy improvement of up to +19.2% and +16.0% vs. the initial models pretrained on a large set of generic keywords. The labeling task is demonstrated on a sensor system composed of a low-power microphone and an energy-efficient Microcontroller (MCU). By efficiently exploiting the heterogeneous processing engines of the MCU, the always-on labeling task runs in real-time with an average power cost of up to 8.2 mW. On the same platform, we estimate an energy cost for on-device training 10x lower than the labeling energy if sampling a new utterance every 6.1 s or 18.8 s with a DS-CNN-S or a DS-CNN-M model. Our empirical result paves the way to self-adaptive personalized KWS sensors at the extreme edge.

Evaluation of factors that affect contrast-detail in digital X-Ray and computed tomography
Creators: name: Alsleem, Haney
Publisher: name: RMIT University
Year: 2024

description: The central aim of this project was to develop a new methodology of evaluation and optimisation of image quality based on low contrast-detail (LCD) detectability performance of computed tomography (CT). This method is well established in digital radiography however similar tool of image evaluation and quality optimisation for CT images are not available. In comparison with other image evaluation methods in digital radiography, the tool of LCD detectability performance—particularly the automated approach—is a good choice for image quality optimisation. This method helps to determine appropriate exposure factors to provide optimum image quality while maintaining a lower radiation dose to patients. This method is a straightforward and direct way to assess image quality as it provides quantitative evaluations of low contrast and small detail measurements of medical images. The subjectivity of image evaluation methods based on human observers is avoided via automated scoring software that is utilised in automated approach of LCD detectability performance. The trade-offs between perceived image quality, diagnosis efficacy and exposure dose can be determined by LCD detectability measurements. A newly designed LCD CT (CDCT) phantom was manufactured and dedicated software was developed with the cooperation of Artinis Medical Systems (Zetten, The Netherlands) for the new evaluation method of LCD detectability.

The specifications of the phantom design were optimised based on the standard recommendations of phantom manufacturing and the requirements of the proposed new evaluation methodology. The CT inverse image quality figure (CTIQFinv) was determined as a measure of LCD detectability performance of CT images. An equation was developed and implemented in the software to calculate and objectively measure CTIQFinv values. The new proposed method of LCD detectability performance was validated by evaluating the influences of exposure factors kVp and mAs, slice thicknesses and object location on image quality in terms of CTIQFinv values based on software and radiographers’ scoring results. The results showed that the new evaluation methodology-based CDCT phantom, along with the automated measurement of CTIQFinv value, had generally shown to be consistent with a prior knowledge of image quality in relation to change of mAs, kVp and slice thickness settings. This work showed that the CDCT phantom and the measurement of CTIQFinv values can provide a measure of CT image quality in terms of LCD detectability performance. This method has a promising role for CT image evaluation and optimisation, and has the potential to effectively evaluate the effects of protocol parameters on image quality of different CT scanners and systems. Future changes to the phantom design and/or software is required to overcome some of the current limitations

description: The asymptotic correspondence between the probability mass function of the $q$-deformed multinomial distribution and the $q$-generalised Kullback-Leibler divergence, also known as Tsallis relative entropy, is established. The probability mass function is generalised using the $q$-deformed algebra developed within the framework of nonextensive statistics, leading to the emergence of a family of divergence measures in the asymptotic limit as the system size increases. The coefficients in the asymptotic expansion yield Tsallis relative entropy as the leading-order term when $q$ is interpreted as an entropic parameter. Furthermore, higher-order expansion coefficients naturally introduce new divergence measures, extending Tsallis relative entropy through a one-parameter generalisation. Some fundamental properties of these extended divergences are also explored.

description: Handling high-dimensional datasets presents substantial computational challenges, particularly when the number of features far exceeds the number of observations and when features are highly correlated. A modern approach to mitigate these issues is feature screening. In this work, the High-dimensional Ordinary Least-squares Projection (HOLP) feature screening method is advanced by employing adaptive ridge regularization. The impact of the ridge tuning parameter on the Ridge-HOLP method is examined and Adaptive iterative ridge-HOLP (Air-HOLP) is proposed, a data-adaptive advance to Ridge-HOLP where the ridge-regularization tuning parameter is selected iteratively and optimally for better feature screening performance. The proposed method addresses the challenges of tuning parameter selection in high dimensions by offering a computationally efficient and stable alternative to traditional methods like bootstrapping and cross-validation. Air-HOLP is evaluated using simulated data and a prostate cancer genetic dataset. The empirical results demonstrate that Air-HOLP has improved performance over a large range of simulation settings. We provide R codes implementing the Air-HOLP feature screening method and integrating it into existing feature screening methods that utilize the HOLP formula.

This trial explored the effects of two different computer-based cognitive rehabilitation (CBCR) programmes on working memory in the chronic phase after ABI, as well as the role of continuous support versus no support from a health professional on the efficacy of CBCR. A total of 72 patients were randomized into four different groups for a 12-week intervention: Two groups trained with the CBCR-programmes ‘Cogmed’ and ‘Brain+ Health,’ respectively, and one group completed active-control training. All three groups received continuous support from a health professional. The last group trained with the CBCR programme ‘Brain+ Health’ but received no support. Before and after the intervention, patients were tested with a neuropsychological battery of working memory, attention and executive functions. Both CBCR-programmes improved working memory when administered with support from a health professional. The programmes improved different sub-components of working memory, possibly because of their individual content and design. None of the CBCR-programmes were more efficacious than sham-training with support. CBCR without support did not improve working memory in patients.

description: Axionlike particles (ALPs) and dark photons (DPs) are viable dark matter particle candidates. We have searched for possible ALP/DP signals in the PandaX-4T liquid xenon detector using 440 kg$\cdot$yr of data. A binned likelihood fit is constructed to search for possible mono-energetic peaks induced by the absorption processes between ALPs/DPs and atomic electrons of xenon. A detailed temporal model of decays associated with xenon isotopes is introduced to constrain the number of background events. No signal excess over background expectations is observed, and we have established the most stringent exclusion limits for most ALP/DP masses across the range of 150 keV/$c^2$ to 1 MeV/$c^2$. The improvement is particularly significant within the mass range of \text{150-400}~keV/$c^2$, with the average factor of 3.5 compared to previous results.

description: Die Autorin und der Autor gehen in ihrer Bachelor-Arbeit der Frage nach, wie Professionelle der Sozialen Arbeit im Rahmen von sportorientierten Angeboten die Selbstkonzeptentwicklung von Jugendlichen beeinflussen können. Das Selbstkonzept umfasst die subjektiven Vorstellungen einer Person über die persönlichen Eigenschaften, Fähigkeiten und Handlungsmöglichkeiten. Jugendliche mit einem stabilen, positiv-realistischen Selbstkonzept haben eine bessere Grundlage, um entwicklungsbedingte Anforderungen und Belastungen zu bewältigen, mit allfälligen Krisen umzugehen und gehen eher davon aus, ihre Zukunftspläne realisieren zu können. Die Analyse von Studien aus der Sportwissenschaft lässt die Folgerung zu, dass der Einfluss von Sport auf das Selbstkonzept bisher nicht eindeutig nachgewiesen werden konnte. Dennoch kann davon ausgegangen werden, dass Sport zu einer höheren Selbstwirksamkeit beiträgt. Diese wiederum beeinflusst das generelle Selbstkonzept. Die Betrachtung des Sportverhaltens von Jugendlichen zeigt, dass ein Interesse an sportlichen Aktivitäten vorhanden ist. Da die sportliche Leistungsverbesserung im Jugendalter im Freizeitsport aber an Stellenwert verliert und soziale Aspekte in den Vordergrund rücken, ist das informelle Bildungspotenzial von sportorientierten Angeboten von besonderer Bedeutung für die Einflussnahme auf die Selbstkonzeptentwicklung. Auf der Handlungsebene werden daher Möglichkeiten aufgezeigt, wie auf einer informellen Ebene positive Selbstwirksamkeitserfahrungen gestaltet werden können.

MACS – a new SPM toolbox for model assessment, comparison and selection

description: In cognitive neuroscience, functional magnetic resonance imaging (fMRI) data are widely analyzed using general linear models (GLMs). However, model quality of GLMs for fMRI is rarely assessed, in part due to the lack of formal measures for statistical model inference. We introduce a new SPM toolbox for model assessment, comparison and selection (MACS, pronounced as “Max”) of GLMs applied to fMRI data. MACS includes classical, information-theoretic and Bayesian methods of model assessment previously applied to GLMs for fMRI as well as recent methodological developments of model selection and model averaging in fMRI data analysis.

MACS is compatible with SPM8 and SPM12 and freely available from GitHub (URL: https://github.com/JoramSoch/MACS). Its key features are (i) simplicity – the toolbox is very easy to use and directly operates on “SPM.mat” files from GLM estimation in SPM; (ii) generality – model assessment and selection are not restricted to special model comparisons, but operate on arbitrary design matrices; (iii) modularity – toolbox features can be combined into unique processing batches or even appended to existing SPM infrastructure; (iv) readability – toolbox code is clearly written for developers and includes extensive comments explaining implementational details; and (v) extendability – the toolbox can be easily augmented with other methods of model assessment. We hope that increased attention on model quality will lead to lower false-positive rates in cognitive neuroscience and increased application of the MACS toolbox will increase the reproducibility of GLM analyses and replicability of fMRI studies.

description: This study presents constructions of the space-time Conservation Element and Solution Element (CESE) methods to accommodate adaptive unstructured quadrilateral meshes. Subsequently, a novel algorithm is devised to effectively manage the mesh adaptation process for staggered schemes, leveraging a unique cell-tree-vertex data structure that expedites the construction of conservation elements and simplifies the interconnection among computational cells. The integration of second-order a-α, Courant number-insensitive, and upwind CESE schemes with this adaptation algorithm is demonstrated. Numerical simulations focusing on compressible inviscid flows are carried out to validate the effectiveness of the extended schemes and the adaptation algorithm.
