Subjects: subject: Biology, Anatomy.

description: Intramuscular EMG of the lateral pterygoid muscles, surface EMG of the temporalis and masseter muscles, electrogoniometry and force measurements of the TMJ were synchronously used to investigate the biomechanical role of the two portions of the lateral pterygoid muscle in relation to internal derangement (ID) of the temporomandibular joint (TMJ). This study dealt with the EMG analysis of five static conditions: resting, resisted protraction, maximum voluntary contraction (MVC) in opening, in molar and incisor clenching of TMJ ID and control subjects. The analysis of variance results of the integrated linear envelop (LE) EMG showed no significant differences between the two groups. The integrated LE EMG of the SLP was significantly lower in the TMJ group during molar clenching (104$\mu$V $\pm$ 60.0 over 159$\mu$V $\pm$ 68.8 for a p =.020). The SLP seemed to have lost its discal stabilizing function during clenching. The integrated LE EMG signals of the ILP were significantly higher in the TMJ ID group during rest, resisted protraction and incisor clenching (p =.029, p =.046, p =.031 respectively). The ILP muscle has probably adapted to control the inner joint instability while continuing its own actions. The results of the isometric forces showed that TMJ ID subjects exhibited significantly lower molar bite forces (297.1N over 419N, p =.042) confirming that they have less muscle strength and tissue tolerance than subjects with healthy masticatory muscle system. Incisor bite forces, however, showed a tendency to be higher in the TMJ ID group (233N over 180.5N, p =.168), possibly resulting from the training of a protracted bite and/or hyperactivity of the ILP associated with ID. Therefore a neuromuscular adaptation could be occurring in TMJ ID masticatory system affecting muscular actions and forces. (Abstract shortened by UMI.)

description: The central nervous system employs control mechanisms in response to both external perturbations and self-perturbations in order to maintain stable upright stance. Previous studies on self-perturbation tasks involving arm movements have examined postural patterns and the relationship between arm movement and the body's center of pressure: however, the coupling within and between the components of the lower limb have yet to be investigated. To examine these issues ten healthy subjects swung their arms inphase and antiphase in the anterior-posterior direction to a metronome at frequencies of 0.67, 0.75, 1.0 and 1.5 Hz. Our results show differences in the phase relationships, joint amplitudes and sway patterns between inphase and antiphase swinging. These findings provide insight into the existence of separate control mechanisms for the two swinging modes, and therefore highlight task-specific control mechanisms for the lower limbs during self-perturbations.
A platform for mobile agent-based data access, retrieval, and interaction.

Subjects: subject: Computer Science.

description: Mobile software agents have emerged as a promising paradigm for computing at both the implementation and conceptual levels. While some will argue that the paradigm is not entirely "new", it is nonetheless more flexible and dynamic than the client-server one. In the mobile agent model the program (e.g. agent) is sent to, and runs on, remote machines and so operates closer and more interactively with the remote resource. This flexible paradigm is well suited to many applications ranging from electronic Internet commerce, to military computing and telecommunication and therefore its exploration and exploitation are paramount to both industry and academia. Designing and abstracting the implementation of a platform using software agents and exposing the paradigm to the user via powerful graphical user interfaces is the general goal of this thesis. While both network bandwidth and user search time can be reduced when the mobile agent is employed for information retrieval on such a platform, enabling this platform requires protocols at the agent language, ontology, transfer, and application levels. To these ends this thesis proposes: (i) an "agent-stack" and protocols that enable automated mobile agent-based digital document access, retrieval, and interaction. AgenTransfer for inter-server transfer, AgenTransact for inter-agent communication, and AgenTask for human-agent communication, (ii) the functionality of an agent execution environment that hosts mobile agents, and (iii) a unique and powerful graphical user interface suite which can be used by novice end-users to quickly and easily program and manage mobile agents and their itineraries. An accompanying implementation of the main components proposed in this thesis serves as both proof-of-concept of the ideas and as an opportunity for analysis.

description: Recent advances in information technology have enabled public organizations and corporations to collect and store huge amounts of individuals' data in data repositories. Such data are powerful sources of information about an individual's life such as interests, activities, and finances. Corporations can employ data mining and knowledge discovery techniques to extract useful knowledge and interesting patterns from large repositories of individuals' data. The extracted knowledge can be exploited to improve strategic decision making, enhance business performance, and improve services. However, person-specific data often contain sensitive information about individuals and publishing such data poses potential privacy risks. To deal with these privacy issues, data must be anonymized so that no sensitive information about individuals can be disclosed from published data while distortion is minimized to ensure usefulness of data in practice. In this thesis, we address privacy concerns in publishing longitudinal data. A data set is longitudinal if it contains information of the same observation or event about individuals collected at several points in time. For instance, the data set of multiple visits of patients of a hospital over a period of time is longitudinal. Due to temporal correlations among the events of each record, potential background knowledge of adversaries about an individual in the context of longitudinal data has specific characteristics. None of the previous anonymization techniques can effectively protect longitudinal data against an adversary with such knowledge. In this thesis we identify the potential privacy threats on longitudinal data and propose a novel framework of anonymization algorithms in a way that protects individuals' privacy against both identity disclosure and attribute disclosure, and preserves data utility. Particularly, we propose two privacy models: (K,C)^P -privacy and (K,C)-privacy, and for each of these models we propose efficient algorithms for anonymizing longitudinal data. An extensive experimental study demonstrates that our proposed framework can effectively and efficiently anonymize longitudinal data.

description: Purpose: The purpose of this study was to inform nursing practice and clinical interventions that support breastfeeding among mothers <24 years of age who resided in a maternity shelter. Methods: Nine young mothers aged 17 to 24, who had initiated breastfeeding, and resided at a maternity shelter, participated in individual semi-structured interviews. This qualitative study was conducted using interpretive description methodology and inductive content analysis. Findings: These young mothers took ownership of their choice to breastfeed and found empowerment in this choice and practice. The institutional and social environments that young mothers experienced were critical to their breastfeeding success. Hospital postpartum nurses had a critical role in the establishment of early breastfeeding by providing a combination of practical hands-on and emotional support to the multifaceted needs of these mothers. Ongoing, accessible, and non-judgemental peer, family, and community support were important to breastfeeding initiation and duration. Conclusion: A combination of emotional and practical supports from multifaceted trusted sources, including professional and peer supports on an ongoing basis are crucial to young at-risk mothers reaching their breastfeeding goals. Implications for clinical practice: Nurses need to focus dually on the practical aspects of breastfeeding while establishing strong therapeutic relationships with this population to successfully provide breastfeeding supports. A combination of accessible and trusted long term professional and peer supports is a key element to designing future breastfeeding support and promotion programs for this population.
Software component interaction testing: Coverage measurement and generation of configurations.
Creators: name: Williams, Alan Webber.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2002
Subjects: subject: Computer Science.

description: Systems constructed from components, including distributed systems, consist of a number of elements that interact with each other. When a system is integrated, there may be undesired interactions among those components that cause system failures. There are two complementary problems in testing a software system. The first problem is to create a test suite, given a description of the expected behaviour of a system configuration. The second problem is to deal with a large number of distinct test configurations. We investigate the second problem in this thesis: the situation when there are various system parameters, each of which can take on a value from a discrete set. The trade-off that the system tester faces is the thoroughness of test configuration coverage, versus availability of limited resources. We introduce a coverage measure that can provide a basis for determining a set of configurations with "sufficient" coverage, or for evaluation of a set of test configurations that already exists. This thesis addresses the problem of testing interactions among components of a software system: the "interaction test coverage" problem. We formally define this problem, and give it a set-theoretic framework. This is done through the introduction of an "interaction element," which becomes the unit of test coverage. The problem is compared to, and distinguished from, the minimum set cover problem and the {0,1} integer programming problem. As a result, the status of the NP-completeness of this problem remains open. Methods from statistical experimental design are introduced, and applied to the problem of generating a set of configurations that achieve coverage of all pair-wise combinations of parameter values. We present a fast, deterministic algorithm to generate such a set of test configurations. The method is compared with other methods, and shown to produce fewer configurations in most situations. The number of configurations generated is logarithmic in the number of parameters, and polynomial in the number of values per parameter. As a result, the number of configurations is usually feasible in practice, and is a significant reduction from the number of possible configurations.

description: The combination of a post-Brexit agricultural policy, the Global Methane Pledge announced during the last United Nations Climate Change Conference in Glasgow (COP26), and urgency of meeting climate goals means the UK has a unique opportunity to create an exemplar through recognition of the benefits of small-scale farm anaerobic digesters that valorise on-site wastes for renewable electricity and heat, cushioning agri-businesses against energy perturbations. To explore economic viability of farm-based biogas production, combinations of support levels, energy prices, capital cost, internal rate of return (IRR), and digestate value were analysed, employing a 550-cow dairy farm with access to other agricultural wastes. A 145 kWe system utilising 100% of CHP electricity (grid value: £0.1361 per kWh) and 70% of the heat (heating oil value: £0.055 per kWh) could achieve an IRR above 15.5% with a median electricity tariff of £0.1104 per kWh at a heat tariff from £0.0309 to £0.0873 per kWh thermal. Under a subsidy-free regime, the same system could achieve a 10% IRR with electricity prices in the range £0.149 to £0.261 per kWh. High fertiliser prices could increase digestate value, further improving viability. With late-2021 high energy prices, the technology approaches subsidy-free viability, but uptake is unlikely unless wider environmental and societal benefits of on-farm systems can be explicitly valued.

description: O presente trabalho publicado nos Anais do II CONGRESSO LÉLIA GONZALEZ: EDUCAÇÃO E DEMOCRACIA aborda a importância de reconhecer e integrar as vivências das mulheres indígenas e quilombolas na educação, destacando a necessidade de uma prática pedagógica que valorize saberes ancestrais e fortaleça identidades étnico-raciais. Com uma abordagem decolonial, o estudo enfatiza a urgência de desafiar narrativas eurocêntricas, promovendo uma educação que respeite a diversidade cultural e a história dessas comunidades. A pesquisa, baseada em uma revisão bibliográfica qualitativa, utiliza conceitos de autores como Alberto Acosta (2016), Ailton Krenak (2020), Antônio Bispo dos Santos (2023), bell hooks (2021), Cida Bento (2022), Lélia Gonzalez (2020), Luiz Rufino (2021) e Paulo Freire (2011), organizando a análise em categorias temáticas para refletir criticamente sobre as implicações sociais da educação decolonial. Os resultados evidenciam que a educação deve descolonizar o pensamento, promover justiça social e valorizar a contribuição das vozes ancestrais femininas na preservação cultural. Em conclusão, o texto reafirma que a educação antirracista e decolonial é fundamental para desmantelar estruturas de opressão, sugerindo que a valorização dos saberes ancestrais e a criação de espaços de diálogo são essenciais para construir uma sociedade justa e plural. A educação deve, portanto, atuar como um agente transformador, promovendo diversidade e justiça social.

description: Perceived occurrences of soundscape reflect cognitive responses to perceived soundscapes. This research focuses on the relationship between perceived occurrences and pleasantness of soundscape in urban forests, and models these parameters. Soundscape information was gathered at 60 observation sites in urban forests, including perceived occurrences of soundscape (POS), pleasantness of perceived soundscape in urban forests (PSUF), and equivalent continuous A-weighted sound pressure level (LAeq). Twelve trained participants were exposed to the soundscape at each site for five minutes and filled out a questionnaire about POS and PSUF. The weight-ratio of perceived occurrences of soundscape (WPOS) was obtained from the POS. Pearson’s correlation coefficients and Stevens’ power law were conducted to test the applicability of the perceived occurrences of soundscape in psychophysical models. Results show that there is an interaction between the WPOS and PSUF in urban forests, and that psychophysical models are able to assess pleasantness of perceived soundscapes in urban forests. Findings show that pleasantness trends of geophony and biophony in broad-leaved forests and those in coniferous forests are opposite when the LAeq is increasing. Furthermore, by combining the WPOS, PSUF, and LAeq, the models were able to link the PSUF of geophony, biophony, anthrophony, and total soundscape in urban forests. Overall, results revealed that perceived occurrences of soundscape play a key role in linking the pleasantness of geophony, biophony, and anthrophony in urban forests.

description: We report results from the initial stage of a long-term pulsar survey of the Galactic plane using the Arecibo L-band Feed Array (ALFA), a seven-beam receiver operating at 1.4 GHz with 0.3 GHz bandwidth, and fast-dump digital spectrometers. The search targets low Galactic latitudes, |b ≤ 5°, in the accessible longitude ranges 32° ≤ l ≤ 77° and 168° ≤ l ≤ 214°. The instrumentation, data processing, initial survey observations, sensitivity, and database management are described. Data discussed here were collected over a 100 MHz passband centered on 1.42 GHz using a spectrometer that recorded 256 channels every 64μs. Analysis of the data with their full time and frequency resolutions is ongoing. Here we report the results of a preliminary, low-resolution analysis for which the data were decimated to speed up the processing. We have detected 29 previously known pulsars and discovered 11 new ones. One of these, PSR J1928+1746, with a period of 69 ms and a relatively low characteristic age of 82 kyr, is a plausible candidate for association with the unidentified EGRET source 3EG J1928+1733. Another, PSR J1906+07, is a nonrecycled pulsar in a relativistic binary with an orbital period of 3.98 hr. In parallel with the periodicity analysis, we also search the data for isolated dispersed pulses. This technique has resulted in the discovery of PSR J0628+09, an extremely sporadic radio emitter with a spin period of 1.2 s. Simulations we have carried out indicate that sim1000 new pulsars will be found in our ALFA survey. In addition to providing a large sample for use in population analyses and for probing the magnetoionic interstellar medium, the survey maximizes the chances of finding rapidly spinning millisecond pulsars and pulsars in compact binary systems. Our search algorithms exploit the multiple data streams from ALFA to discriminate between radio frequency interference and celestial signals, including pulsars and possibly new classes of transient radio sources.
Three-dimensional coherent transfer function for reflection confocal microscopy in the presence of refractive-index mismatch

description: The three-dimensional (3-D) coherent transfer function for reflection confocal microscopy of high-numerical-aperture objectives is derived and calculated in the presence of refractive-index mismatch when a laser beam is focused into a medium of refractive index different from its immersion medium. This aberrated coherent transfer function is then used to estimate the readout efficiency of 3-D data bits recorded in a thick medium. It is shown that the readout efficiency of confocal microscopy for 3-D bit data storage is decreased with the focal depth of an objective in a recording medium. However, a high readout efficiency can be maintained if the tube length of a reading objective is linearly altered to compensate for the spherical aberration caused by the refractive-index mismatch.

description: Periods of summertime low flows are often critical for fish. This study quantified the impacts of forest clearcutting on summertime low flows and fish habitat and how they evolved through time in two snowmelt-dominant headwater catchments in the southern interior of British Columbia, Canada. A paired-catchment analysis was applied to July-September water yield, the number of days each year with flow less than 10% of mean annual discharge, and daily streamflow for each calendar day. The post-harvest time series were divided into treatment periods of approximately 6-10 years, which were analyzed independently to evaluate how the effects of forestry changed through time. An instream flow assessment using a physical habitat simulation (PHABSIM)-style approach was used to relate streamflow to the availability of physical habitat for resident rainbow trout. About two decades after the onset of logging and as the extent of logging increased to approximately 50% of the catchments, reductions in daily summertime low flows became more significant for the JulySeptember yield (43%) and for the analysis by calendar day (11-68%). Reductions in summertime low flows were most pronounced in the catchment with the longest post-harvest time series. Based on the temporal patterns of response, we hypothesize that the delayed reductions in late-summer flow represent the combined effects of a persistent advance in snowmelt timing in combination with at least a partial recovery of transpiration and interception loss from the regenerating forests. These results indicate that asymptotic hydrological recovery as time progresses follow logging is not suitable for understanding the impacts of forest harvesting on summertime low-flows. Additionally, these reductions in streamflow corresponded to persistent decreases in modelled fish habitat availability that typically ranged from 20-50% during the summer low-flow period in one of the catchments, suggesting that forest harvest may have substantial delayed effects on rearing salmonids in headwater streams.

description: Cette thèse défend l’idée que, dans la lignée des événements qui ont suivi les attentats terroristes du 11 septembre 2001, le paradigme de la gestion du risque est devenu central dans les études de sécurité et dans les analyses de relations internationales. Dans le climat de risque engendré par les actes de terreur, le discours politique a mis en œuvre une biopolitique de la peur dans le but de normaliser les populations. Conséquemment, la surveillance est devenue une méthode de gouvernance de la société du risque, elle-même née d’une culture de la peur et du risque. Cette société du risque est construite politiquement et véhiculée par des récits précis qui ont pour but de gouverner un monde qui se gère de plus en plus difficilement, comme le montre l’ambiguïté des interprétations données aux attentats du 11 septembre 2001 et des différents langages pour les expliquer.

description: The sharing of the same food source among parents and offspring can be a driver of the evolution of family life and parental care. However, if all family members desire the same meal, competitive situations can arise, especially if resource depletion is likely. When food is shared for reproduction and the raising of offspring, parents have to decide whether they should invest in self-maintenance or in their offspring and it is not entirely clear how these two strategies are balanced. In the burying beetle Nicrophorus vespilloides, parents care for their offspring either bi- or uniparentally at a vertebrate carcass as the sole food source. The question of whether biparental care in this species offers the offspring a better environment for development compared with uniparental care has been the subject of some debate. We tested the hypothesis that male contribution to biparental brood care has a beneficial effect on offspring fitness but that this effect can be masked because the male also feeds from the shared resource. We show that a mouse carcass prepared by two Nicrophorus beetles is lighter compared with a carcass prepared by a single female beetle at the start of larval hatching and provisioning. This difference in carcass mass can influence offspring fitness when food availability is limited, supporting our hypothesis. Our results provide new insights into the possible evolutionary pathway of biparental care in this species of burying beetles.

description: The interplay between oligodendrocyte (OL) and extracellular matrix (ECM) is critical to the proper maturation of this unique cell type. Recent work has established the β1 integrin-signaling pathway, a mediator for ECM/OL interactions, as an essential component of myelin sheath formation in the central nervous system (CNS). A major downstream effector of β1 integrin is integrin-linked kinase (ILK), an adaptor and structural platform protein. Herein, we (1) generated a model system to study ILK in vivo and (2) employed the model to elucidate ILK’s role in regulating OL biology. To assess the importance of ILK in OL-mediated myelination, we ablated ILK in primary OLs. ILK loss delayed morphological maturation and led to filamentous actin accumulation in the processes and cell body. Further, we noted an upregulation in RhoA activity, with pathway inhibition rescuing an OL subset. We next moved our studies in vivo. First, we assessed the proteolipid protein promoter’s utility as OL-specific Cre driver. Protocols established, we generated an ILK conditional knockout line (Ilk cKO). Ultrastructural analysis of Ilk cKO optic nerves revealed increased number of amyelinated nerve fibers at P14 with subsequent recovery by P28. The observed transient defects were due neither to a loss nor a gain in total number of mature or progenitor OLs. To rationalize recovery, we grew ILK-depleted OLs on an “inert” substrate. Here, while morphology improved, ILK-depleted OLs were characterized by enlarged and sluggish growth cones as well as microtubule disorganization. Taken together, our data suggests a role for ILK in regulating the morphological maturation of OLs both in vitro and in vivo, the loss of which results in defective OL branching and membrane formation with phenotype and subsequent recovery dependent upon niche complexity.

description: One of the largest problems in current medicine is the shortage of organs for transplant due to technological limitations in the storage of organs for any length of time. A possible solution to this problem would involve cryopreservation. However, current cryopreservatives such as sucrose or DMSO have concerning cytotoxic issues that limit their possible applications. A major cause of cryoinjury is the uncontrolled recrystallization of inter and intra-cellular ice crystals that occurs during the thawing process leading to mechanical damage and dehydration. The Ben lab has thus been interested in the design of compounds that are capable of inhibiting this process but do not possess other undesirable properties found in the native compounds. These synthetic analogues have been shown to increase cellular viability post-thaw. A series of mixed α/β glycopeptides are prepared and analyzed for antifreeze properties. The results of this study imply that it is not the gross conformation of the glycopeptide that is responsible for activity, but rather that intramolecular relationships may be responsible for disrupting the reorganization of ice. A technique was devised for the incorporation of triazoles into the analogues to investigate the importance of the linker and to greatly simplify the synthesis of a library of glycoconjugates. It was found that the IRI activity of glycopeptides is very sensitive to the distance between carbohydrate and peptide backbone. The electron density at the anomeric oxygen is an important parameter with respect to intramolecular networks. A series of substituted galactosides is presented that modify the electronics of the anomeric oxygen. The results demonstrate that decreasing electron density at this position appears to improve IRI activity in a predictable manner. To better understand the remarkable IRI activity of a key analogue, it was systematically truncated. This study led to the serendipitous discovery of a series of very highly IRI active analogues that do not contain a peptide backbone. These compounds represent the first non-glycopeptides that can show very significant IRI activity even at very low concentrations. The final portion of the thesis reports the efforts towards the preparation of a carbasugar analogue of AFGP-8.

description: Obesity is a major health concern with cardiometabolic co-morbidities, affecting more than 650 million people worldwide. Here, I have assessed the contribution of common and rare genetic variation to adiposity and metabolic phenotypes, including identifying genetic factors influencing location of abdominal fat storage. A GWAS of MRI-measured abdominal fat distribution in the UK Biobank (UKBB) identified two novel SNPs at genome-wide significant level: i) in both men and women, rs182052 in ADIPOQ associated with higher visceral adiposity (β=0.114 SD; P=3.04×10-8) and ii) in women only, rs181635166 in NALCN associated with having more subcutaneous abdominal fat (βfemales=0.338 SD, Pfemales=1.51×10-8). A genetic risk score (GRS) composed of “favourable adiposity” SNPs, was associated with 0.040 (0.008) SD (P=1.08×10-6) lower liver fat and preferential lower body, rather than central, adiposity, in women only. In men, it was associated with a higher adiposity overall. Attention was then turned to examination of the phenotypic implications of rarer genetic variants, revealing that a predicted-deleterious, low frequency variant, rs11568563 (c.A516C, p.E172D, MAF=0.045) in SLCO1A2, conferred diminished and delayed post-prandial increase of conjugated bile acids in plasma, compared to non-carriers, after nutritional challenge tests (OGTT and MMTT): this may have important implications for cardiovascular risk and diabetes. Finally, I examined the phenotypic implications of mutations in the MC4R gene – the commonest form of monogenic obesity. The combined prevalence of 72 rare reportedly-deleterious MC4R mutations in the White British participants of the UKBB (N~330,000) was 0.39%, but only 8/72 mutations showed full penetrance for obesity (S19fs, P48S, N62S, L106P, S136P, F261S, P299H or A303T). There was slight enrichment of LoF mutations in overweight/obese compared to underweight/lean individuals (132 carriers (0.1%) vs 49 carriers (0.04%), P=0.04). This work highlights the need to consider penetrance and expressivity in genetic counselling of families with MC4R mutations.

description: Mathematical models displaying travelling waves appear in a variety of domains. These waves are often faced with different kinds of perturbations. In some cases, these perturbations result in propagation failure, also known as wave-blocking. Wave-blocking has been studied in the case of several specific models, often with the help of numerical tools. In this thesis, we will display a technique that uses symmetry and a center manifold reduction to find a criterion which defines regions in parameter space where a wave will be blocked. We focus on waves with low velocity and small symmetry-breaking perturbations, which is where the blocking initiates; the organising center. The range of the tools used makes the technique easily generalizable to higher dimensions. In order to demonstrate this technique, we apply it to the bistable equation. This allows us to do calculations explicitly. As a result, we show that wave-blocking occurs inside a wedge originating from the organising center and derive an expression for this wedge to leading order. We verify our results with some numerical simulations.

description: The aim of this qualitative study was to look at social capital formation among at-risk students in an alternative education program. Social capital has been applied to a broad range of fields to highlight the benefits that individuals, organizations and communities accrue from supportive relationships and networks. However, to date no research has looked specifically at social capital formation among at-risk students in a Canadian alternative high school. For this reason the author decided to examine the lived experiences of twelve Canadian at-risk students currently attending Sunnyside Alternative High School, with the aim of describing how social capital was fostered. The mainstream school and alternative school experiences of the students were compared based on the research questions and a conceptual framework of social capital formation. The findings of the research confirmed the importance of affective bonding social capital, as well as an inclusive learning environment at the alternative school.

Action Potential Initiation in a Damaged Axon Initial Segment

description: We constructed a model for the initiation of the action potential (AP) in a damaged axon initial segment(AIS). We modelled the full axon including the AIS with a system of partial differential equations that we solved numerically. The damage was modelled on the AIS by having selected voltage-gated sodium channels affected by a coupled left-shift (CLS) of their activation and inactivation gating dynamics. We found that increased CLS lowered the threshold of spike initiation. We also found that CLS decreased the delay of spike initiation, especially for longer AIS. We also found that variability in the initiation timing increased with CLS. We also explored the effect of the geometry of the AIS on the initiation, finding that decreasing the radius favoured the initiation in the distal part of the AIS.
