Role of somatostatin receptors in epidermal growth factor mediated EGFR signaling in breast cancer and human embryonic kidney 293 cells
Creators: name: Kharmate, Geetanjali
Publisher: name: University of British Columbia

description: Epidermal growth factor receptor (ErbB1) and somatostatin receptors (SSTRs) exert opposing effects on tumor promoting signaling pathways. Whether SSTRs functionally interact with ErbB1 and modulate tumor-promoting signaling is currently unknown. For this reason, the specific emphasis of this thesis is to examine the role of SSTRs in ErbB1 mediated signaling in breast cancer cells and human embryonic kidney (HEK) 293 cells. First, I determined the mRNA and protein expression of SSTR1, SSTR5 and ErbB1 in human breast cancer cell lines namely MCF-7 and MDA-MB231. I next demonstrated that SSTR1 or 5 exist as pre-formed heterodimers with ErbB1, which dissociated in an agonist dependent manner. Somatostatin (SST) modulated epidermal growth factor (EGF) mediated MAPK in a time and agonist dependent manner. Furthermore, SST and/or EGF treatment altered the expression of key adapter proteins including Grb2, SOS, Shc, SH-PTP1 and SH-PTP2, which are known to play a role in MAPK activation. Since breast cancer cells endogenously express SSTR and ErbB subtypes, this study was further extended in HEK-293 to gain insight into the effect of individual SSTR on ErbB1 activated signaling. We demonstrated that HEK-293 cells transfected with SSTR1, SSTR5 or SSTR1/5 negatively regulate EGF mediated effects attributed to the inhibition of ErbB1 phosphorylation, MAPKs and PI3K/AKT pathways. Moreover, SST effects were significantly enhanced in cells when ErbB1 was knocked down using small interference ribonucleic acid (siRNA) or treated with selective ErbB1 antagonist (AG1478). The presence of SSTRs, in addition to modulating signaling pathways, led to the dissociation of constitutive and EGF induced heteromeric complex of ErbB1/ErbB2. Most significantly, cells co-transfected with SSTR1/5 display pronounced effects of SST on the signaling and dissociation of the ErbB1/ErbB2 heteromeric complex than cells expressing either SSTR1 or 5 alone. The findings of this study discovered a new mechanism and potential role of SSTRs in attenuation of ErbB1 mediated signaling pathways via dissociation of ErbB1/ErbB2 heteromeric complex. In conclusion, the results presented in this thesis suggest that formulating novel drugs that activate SSTRs along with inhibition of ErbB1 might likely serve as an important therapeutic approach in the treatment of ErbBs positive tumors.

description: Secret-dependent timing behavior in cryptographic implementations has resulted in exploitable vulnerabilities, undermining their security. Over the years, numerous tools to automatically detect timing leakage or even to prove their absence have been proposed. However, a recent study at IEEE S&P 2022 showed that, while many developers are aware of one or more analysis tools, they have major difficulties integrating these into their workflow, as existing tools are tedious to use and mapping discovered leakages to their originating code segments requires expert knowledge. In addition, existing tools focus on compiled languages like C, or analyze binaries, while the industry and open-source community moved to interpreted languages, most notably JavaScript. In this work, we introduce Microwalk-CI, a novel side-channel analysis framework for easy integration into a JavaScript development workflow. First, we extend existing dynamic approaches with a new analysis algorithm, that allows efficient localization and quantification of leakages, making it suitable for use in practical development. We then present a technique for generating execution traces from JavaScript applications, which can be further analyzed with our and other algorithms originally designed for binary analysis. Finally, we discuss how Microwalk-CI can be integrated into a continuous integration (CI) pipeline for efficient and ongoing monitoring. We evaluate our analysis framework by conducting a thorough evaluation of several popular JavaScript cryptographic libraries, and uncover a number of critical leakages.

description: We show how to construct nonnegative low-rank approximations of nonnegative tensors in Tucker and tensor train formats. We use alternating projections between the nonnegative orthant and the set of low-rank tensors, using STHOSVD and TTSVD algorithms, respectively, and further accelerate the alternating projections using randomized sketching. The numerical experiments on both synthetic data and hyperspectral images show the decay of the negative elements and that the error of the resulting approximation is close to the initial error obtained with STHOSVD and TTSVD. The proposed method for the Tucker case is superior to the previous ones in terms of computational complexity and decay of negative elements. The tensor train case, to the best of our knowledge, has not been studied before.

description: The learning laboratory is a common and important component of contemporary Canadian post-secondary engineering education, intended to relate practice and theory, provide a practical experience in what can be a largely theoretical program, and motivate students. However, a significant minority of mechanical and manufacturing engineering students in a third-year materials science course at the University of Calgary have, across the last decade, reported on their end-of-course surveys that they do not perceive any connections between their laboratories and either their careers or their lectures. Simultaneously, there have been calls from local industry, the provincial government of Alberta that regulates and funds the program, and University administration for more experiential opportunities to be included in undergraduate programs to better prepare students for their future employment. Given that engineering education is directly related to professional engineering practice, it is key that students perceive connections between their program and industrial applications. Therefore, the research question is, how can established educational scholarship be applied to undergraduate engineering laboratories in order to improve students’ perception of their learning experience? Established educational scholarship and expectations from the Government of Alberta and the University of Calgary were reviewed. Qualitative surveys were developed using this scholarship and released to University of Calgary students currently enrolled in the third-year materials science course, asking them to identify and assess learning levels in their laboratories past and present and how course actions affected their assessment. A second series of surveys was released to members of local engineering industry with experience managing students and graduates of the University program, identifying what value they see in engineering learning laboratories. Analysis of results and scholarship provided a set of recommendations for improving the student laboratory learning experience. The core principles of these recommendations are to communicate clearly and explicitly with students, to constructively align all components of the laboratory experience, and to include hands-on participatory experiences whenever possible. Further recommendations targeted implementation of these principles in the laboratory pedagogy, within the laboratory itself as experienced by students, in the laboratory assessment, and in laboratory facilitators such as teaching assistants and technicians.

description: Micro-blogging systems such as Twitter expose digital traces of social discourse with an unprecedented degree of resolution of individual behaviors. They offer an opportunity to investigate how a large-scale social system responds to exogenous or endogenous stimuli, and to disentangle the temporal, spatial and topical aspects of users' activity. Here we focus on spikes of collective attention in Twitter, and specifically on peaks in the popularity of hashtags. Users employ hashtags as a form of social annotation, to define a shared context for a specific event, topic, or meme. We analyze a large-scale record of Twitter activity and find that the evolution of hastag popularity over time defines discrete classes of hashtags. We link these dynamical classes to the events the hashtags represent and use text mining techniques to provide a semantic characterization of the hastag classes. Moreover, we track the propagation of hashtags in the Twitter social network and find that epidemic spreading plays a minor role in hastag popularity, which is mostly driven by exogenous factors.

description: Wetlands comprise 65% of the Athabasca Oil Sands Region (AOSR) surface mineable area and thus support diverse flora (approximately 400 species in Alberta). Due to increased anthropogenic land disturbance activities such as bitumen extraction, reclamation of surface mineable areas will also increase. The resulting reclaimed areas will tend to be sodium-enriched compared to pre-disturbance landscapes. In this thesis, forty young (<40 years old) stratified-randomly selected wetlands were sampled on reclaimed landscapes at Syncrude’s Mildred Lake lease and from reference wetlands in adjacent areas in the AOSR to determine how salinity and age influence the vegetation community composition, and the biomass of six dominant wetland plant species (Carex aquatilis, Calamagrostis canadensis, Carex atherodes, Carex utriculata, Schoenoplectus tabernaemontani, and Typha latifolia) found on reclaimed and reference landscapes. Wetland vegetation communities on reclaimed landscapes differed from those on reference landscapes; however, landscape type had no impact on the biomass of the dominant plant species. Vegetation communities varied along a salinity gradient; species richness was negatively associated with salinity, and vegetative species abundance (percent cover) was lowest in freshwater wetlands and highest in moderately brackish wetlands. Species richness did not differ among wetland classes. However, vegetative species abundance was significantly different among age classes. The biomass produced by each dominant species did not vary with respect to a gradient of salinity or among wetlands of different age classes. These findings may provide a useful frame of reference against which to compare vegetation communities that may be observed in wetlands forming on reclaimed landscapes.

description: Monoclonal antibody solutions are set to become a major therapeutic tool in the years to come, capable of targeting various diseases by clever designing their antigen binding site. However, the formulation of stable solutions suitable for patient self-administration typically presents challenges, as a result of the increase in viscosity that often occurs at high concentrations. Here, we establish a link between the microscopic molecular details and the resulting properties of an antibody solution through the characterization of clusters, which arise in the presence of self-associating antibodies. In particular, we find that experimental small-angle X-ray scattering data can be interpreted by means of analytical models previously exploited for the study of polymeric and colloidal objects, based on the presence of such clusters. The latter are determined by theoretical calculations and supported by computer simulations of a coarse-grained minimal model, in which antibodies are treated as Y-shaped colloidal molecules and attractive domains are designed as patches. Using the theoretically-predicted cluster size distributions, we are able to describe the experimental structure factors over a wide range of concentration and salt conditions. We thus provide microscopic evidence for the well-established fact that the concentration-dependent increase in viscosity is originated by the presence of clusters. Our findings bring new insights on the self-assembly of monoclonal antibodies, which can be exploited for guiding the formulation of stable and effective antibody solutions.

description: A new approach for the classification of the cosmic web is presented. In extension of the previous work of Hahn et al. (2007) and Forero-Romero et al. (2009) the new algorithm is based on the analysis of the velocity shear tensor rather than the gravitational tidal tensor. The procedure consists of the construction of the the shear tensor at each (grid) point in space and the evaluation of its three eigenvectors. A given point is classified to be either a void, sheet, filament or a knot according to the number of eigenvalues above a certain threshold, 0, 1, 2, or 3 respectively. The threshold is treated as a free parameter that defines the web. The algorithm has been applied to a dark matter only, high resolution simulation of a box of side-length 64$h^{-1}$Mpc and N = $1024^3$ particles with the framework of the WMAP5/LCDM model. The resulting velocity based cosmic web resolves structures down to <0.1$h^{-1}$Mpc scales, as opposed to the ~1$h^{-1}$Mpc scale of the tidal based web. The under-dense regions are made of extended voids bisected by planar sheets, whose density is also below the mean. The over-dense regions are vastly dominated by the linear filaments and knots. The resolution achieved by the velocity based cosmic web provides a platform for studying the formation of halos and galaxies within the framework of the cosmic web.

description: This document is a Section 106 report that discusses a project that was designed to collect planning information for location of the Space Transportation System (STS) facilities on VAFB. This study was to include a survey or inventory of archaeological resources within the project area defined as a twenty-one mile long, 3,000' wide, coastal corridor extending from just north of the Santa Ynez River to a point south of Point Arguello. In addition, selected sites were to be tested, mapped, and evaluated. A major problem impacting this endeavor, from the initial planning stages to report preparation was a lack of adequate precendents to guide this research. The evaluation of significance of archaeological sites in terms of criteria specified in Federal mandates is a recent obligatory activity that is still being refined. Archaeologists have not previously used the term "significance" in a legalistic fashion, nor have they used this as guidance for the prediction of salvage excavation costs, thus this report may set several precedents. Limited lead time (<1 month) for planning and preparation led to a degree of disorganization and misdirected effort and rigor for certain data types.
Preparing for Climate-Related Migration: An Exploratory Assessment of Capacities and Barriers Facing Calgary-based Immigrant Serving Agencies in Responding to Climate Change

description: This thesis uses climate justice as a conceptual framework to explore the capacities and barriers of immigrant-serving agencies (ISA) in Calgary, Alberta, in responding to climate migration. The research addresses the limited research conducted in Canada on climate migration and policies at different government levels. This study uses an exploratory qualitative case study approach to answer two research questions. Firstly, to what extent are ISA addressing climate change and climate migration in policies and programs, and secondly, what policies and programs can improve ISA's capacity to address climate migration? The study finds that ISA plays a crucial role in serving the immigrant population in Calgary, with their operations divided into three core areas: education, employment, and socio-cultural. However, ISA's readiness to include climate migrants remains a significant barrier. Five themes emerged from the interview data: funding, policy gaps, restrictive criteria, preparedness, and the need for agencies to support climate justice through EDI (specifically anti-racism) training. The study recommends introducing an officially stated policy on climate migration, which can be achieved in several ways, for instance, by considering climate migrants under section 25 of the Immigration and Refugee Act, holding temporary removal orders, or relaxing the eligible criteria restrictions. To empower climate migrants and enhance their representation, one potential approach is to include ISA as members of a national climate change advisory board or committee. ISAs, as front-line workers familiar with the experiences and needs of immigrant communities, can provide valuable insights and perspectives in shaping climate change policies and strategies. Their inclusion would ensure that the National Adaptation Strategy considers the challenges faced by climate migrants and incorporates their voices into decision-making processes. This research contributes to the literature by addressing the significant gap in research, policy, programming and practices on the climate migration nexus and ISA's capacities and barriers. It also highlights the need for addressing climate migration in policies and programs at different government levels, which can contribute to climate justice and support climate-vulnerable communities.

description: In windy conditions, the air is turbulent. The strong and intermittent velocity variations of turbulence are invisible to flying animals. Nevertheless, flying animals, not much larger than the smallest scales of turbulence, manage to maneuver these highly fluctuating conditions quite well. Here we quantify honeybee flight with time-resolved three-dimensional tracking in calm conditions and controlled turbulent winds. We find that honeybee mean speed and acceleration are only weakly correlated with the strength of turbulence. In flight, honeybees accelerate slowly and decelerate rapidly, i.e., they break suddenly during turns and then accelerate again. While this behavior is observed in both calm and turbulent conditions, it is increasingly dominant under turbulent conditions where short straight trajectories are broken by turns and increased maneuvering. This flight-crash behavior is reminiscent of turbulence itself. Our observations may help the development of flight strategies for miniature flying robotics under turbulent conditions.

Principles, process, responsibility : exploring ethics as a meta-regulatory framework for evolving governance discourse
Creators: name: Dempsey, Alison Louise
Publisher: name: University of British Columbia
Year: 2012

description: This thesis proposes a new paradigm for understanding, developing and maintaining standards of corporate governance and conduct based on ethics as a meta-regulatory framework for governance discourse. It explores the possibility that, within such a framework, the explicit recognition of fundamental norms of ethical conduct and decision making such as honesty, fairness, consideration of others, responsibility and trustworthiness would precede and inform policy decisions relating to the objectives, structure and regulatory approaches of particular governance systems and practical considerations of how to implement and operationalize governance practices. It suggests that, despite the complex legal, institutional, normative and social dimensions of corporate governance standards and practice, these ethical norms are already implicit, and more recently explicit, in the formal systems of laws, rules and standards that seek to regulate corporate conduct. Alongside these traditional governance regulatory mechanisms, informal and soft law governance standards − codes, guidelines, international and multi-partite commitments − have emerged as an influential source of explicitly ethical, values based beliefs and expectations of what constitutes responsible business. There is an opportunity to use these ethical norms as a common point of departure for future governance discourse that is broad enough to support multiple approaches to governance yet flexible enough to accommodate complexity, diversity and change. Such discourse has the potential to alleviate some of the inherent interpretive and practical challenges to reconciling culturally diverse and pluralistic regulatory approaches in the pursuit of effective global corporate governance standards.

description: We study the ability of future weak lensing (WL) surveys to constrain primordial non-Gaussianity of the local type. We use a large ensemble of simulated WL maps with survey specifications relevant to Euclid and LSST. The simulations assume Cold Dark Matter cosmologies that vary certain parameters around fiducial values: the non-Gaussianity parameter f_NL, the matter density parameter Omega_m, the amplitude of the matter power spectrum sigma_8, the spectral index of the primordial power spectrum n_s, and the dark-energy equation-of-state parameter w_0. We assess the sensitivity of the cosmic shear correlation functions, the third-order aperture mass statistics, and the abundance of shear peaks to these parameters. We find that each of the considered probes provides unmarginalized constraints of Delta f_NL ~ 20 on f_NL. Marginalized constraints from any individual WL probe are much weaker due to strong correlations between parameters. However, the parameter errors can be substantially reduced by combining information from different WL probes. Combining all WL probes yields the following marginal (68% confidence level) uncertainties: Delta f_NL ~ 50, Delta Omega_m ~ 0.002, Delta sigma_8 ~ 0.004, Delta n_s ~ 0.007, and Delta w_0 ~ 0.03. We examine the bias induced by neglecting f_NL on the constraints on the other parameters. We find sigma_8 and w_0 to be the most affected. Moreover, neglecting non-Gaussianity leads to a severe underestimation of the uncertainties in the other cosmological parameters.

Allegory and Apocatastasis: Walter Benjamin and the Image of Neoliberalism

description: This dissertation argues that Walter Benjamin’s image of allegory as at once an encounter with a “ruin” and “a petrified, primal landscape” can only be analysed through the prism of a wider critical program that takes into consideration a larger aggregate of his key concepts. The term apocatastasis does not appear often in his writings, but it refers to a sudden intensity of recognition wherein “the entire past is brought into the present.” Rather than a mythic moment of total knowledge, this dissertation argues that Benjamin uses apocatastasis to conceptualize the recognition and preservation of dialectically (i.e., historically) cancelled values. This moment of recognition, or Jetztzeit, corresponds to an authentic political experience—an understanding that the present is not a repetition of previous historical events, but a unique string of values that requires unique, political actualization. Apocatastasis, as this dissertation conceives of it, is a mode of reading that places three key terms in tension: allegory, image, and secularization. These three terms contain a multitude of others that all contextualize the scene of an encounter with some ruined, historical phenomenon (allegory). This dissertation will then use this reading method to critique the ruin of neoliberalism—an allegorical scene par excellence. Through Benjamin’s unfinished writings about the allegorical nature of the commodity form, this dissertation argues that the unique value that emerges in neoliberalism is display value. Display value enables the reification of—and the continuing commodification of—language itself, in ways that were still developing in classical liberalism. With the origins of this value emerging in Baudelaire’s Paris, this dissertation will also attempt to contextualize the extent to which display alters the scene that is still unrecognizable as anything but liberalism to the majority of readers today.

description: Single-molecule force spectroscopy (smFS) is a powerful approach to studying molecular self-organization. However, the coupling of the molecule with the ever-present experimental device introduces artifacts, that complicates the interpretation of these experiments. Performing statistical inference to learn hidden molecular properties is challenging because these measurements produce non-Markovian time-series, and even minimal models lead to intractable likelihoods. To overcome these challenges, we developed a computational framework built on novel statistical methods called simulation-based inference (SBI). SBI enabled us to directly estimate the Bayesian posterior, and extract reduced quantitative models from smFS, by encoding a mechanistic model into a simulator in combination with probabilistic deep learning. Using synthetic data, we could systematically disentangle the measurement of hidden molecular properties from experimental artifacts. The integration of physical models with machine learning density estimation is general, transparent, easy to use, and broadly applicable to other types of biophysical experiments.

description: The Pell’s equation and the negative Pell’s equation are two of the most well-studied topics in number theory. While the solvability of the Pell’s equation over the integers is well known for centuries, the solvability problem of the negative Pell’s equation over the integers, especially the density problem of how likely the negative Pell’s equation is solvable, was not fully answered until recently. In this thesis, we consider these equations over the polynomial ring F[t] where F is a finite field whose characteristic is greater than 2. In Chapter 3 of this thesis, two different well-known proofs of the solvability of the Pell’s equation over F[t] are presented. In Chapter 4, we present conditions and examples of when the negative Pell’s equation is solvable and the function field analogue of the density problem on the negative Pell’s equation.

description: CHARACTERS OF ENCYRTIDAE  Within the Chalcidoidea, the Encyrtidae can be distinguished by six major characters:
1. Head with dorsal tentorial arms reaching the frontovertex between the inner eye margin and torulus. This character state is present in almost all Encyrtidae and has been reported elsewhere only in Eunotidae (Dzhanokmen, 2000). It may be a synapomorphy of these two families.
2. Fore wing with a well-defined linea calva (see Terms and Measurements above). A true linea calva is known only in Encyrtidae, many Aphelininae (Aphelinidae) and a few Eupelmidae.
 3. Mesopleuron convex and not divided obliquely into separate parts. This character is characteristic of jumping taxa inlcuding Encyrtidae, Tanaostigmatidae, some Eupelmidae and a few Aphelinidae, e.g. Coccobius. Other Aphelinidae have the mesopleuron somewhat similar in appearance, but have an indistinct, posterior, transverse division, e.g. Eutrichosomella.
4. Mid coxa inserted level with mid-line of mesopleuron. So far as it is known, this is an autapomorphy for Encyrtidae.
 5. Cerci advanced towards anterior of gaster, sometimes even into anterior half. This character state is present in all Encyrtidae except two genera, Oriencyrtus and Oesol. Some representatives of other families may have the cerci slightly advanced, but never so strongly, e.g. Aphelinidae and Eupelmidae.
 6. Outer plates of the ovipositor completely separated from tergite IX of abdomen (Encyrtinae) or connected by an elongate sclerotised strip (paratergite) (Tetracneminae). Both features almost certainly result from advancement of the cerci. Outside the Encyrtidae there are no taxa where the outer plates of the ovipositor are completely separated from abdominal tergite IX. However, in some Coccophagus (Aphelinidae) the cerci may be slightly advanced and the connection may be very weak via a very narrow filamentous strip, similar to the paratergites of some Tetracneminae.

description: The transfer of entanglement from optical fields to qubits provides a viable approach to entangling remote qubits in a quantum network. In cavity quantum electrodynamics, the scheme relies on the interaction between a photonic resource and two stationary intracavity atomic qubits. However, it might be hard in practice to trap two atoms simultaneously and synchronize their coupling to the cavities. To address this point, we propose and study entanglement transfer from cavities driven by an entangled external field to controlled flying qubits. We consider two exemplary non-Gaussian driving fields: NOON and entangled coherent states. We show that in the limit of long coherence time of the cavity fields, when the dynamics is approximately unitary, entanglement is transferred from the driving field to two atomic qubits that cross the cavities. On the other hand, a dissipation-dominated dynamics leads to very weakly quantum-correlated atomic systems, as witnessed by vanishing quantum discord.

description: Proving linearizability of concurrent data structures remains a key challenge for verification. We present temporal interpolation as a new proof principle to conduct such proofs using hindsight arguments within concurrent separation logic. Temporal reasoning offers an easy-to-use alternative to prophecy variables and has the advantage of structuring proofs into easy-to-discharge hypotheses. To hindsight theory, our work brings the formal rigor and proof machinery of concurrent program logics. We substantiate the usefulness of our development by verifying the linearizability of the Logical Ordering (LO-)tree and RDCSS. Both of these involve complex proof arguments due to future-dependent linearization points. The LO-tree additionally features complex structure overlays. Our proof of the LO-tree is the first formal proof of this data structure. Interestingly, our formalization revealed an unknown bug and an existing informal proof as erroneous.

description: We consider the K-body local correlations in the (repulsive) 1D Bose gas for general K, both at finite size and in the thermodynamic limit. Concerning the latter we develop a multiple integral formula which applies for arbitrary states of the system with a smooth distribution of Bethe roots, including the ground state and finite temperature Gibbs-states. In the cases K<=4 we perform the explicit factorization of the multiple integral. In the case of K=3 we obtain the recent result of Kormos et.al., whereas our formula for K=4 is new. Numerical results are presented as well.

description: The behaviour of slender concrete masonry walls is poorly understood. This is particularly evident by the treatment of such walls in the Canadian masonry design standard, CSA S304-14. Many researchers have noted the poor accuracy of CSA S304-14’s provisions and the need for more experimental data. A major limiting factor to building and testing walls is their size and the quantity of materials used. This limitation can be overcome by using half-scale walls – however, it must first be proven that scale effects do not influence the results obtained. Of further utility would be a verified finite-element model to predict wall failure loads and modes with a high degree of confidence. Towards these ends, twelve masonry walls, six at full-scale and six corresponding half-scale walls, were built and tested under an axial load with an eccentricity of 1/3 of the wall thickness; single curvature moment was applied. Digital image correlation (DIC) was used to acquire lateral displacement data; its implementation in this study is presented. Specimen handling procedures are also presented. Wall strengths, lateral displacement profiles and behaviour were recorded and are presented. Experimental results show that size effect does not influence the behaviour and strength of slender concrete masonry walls at half-scale. Experimental results are used to discuss shortcomings in CSA S304-14’s treatment of wall effective stiffness. A verified finite element model was also used to investigate the failure load and mode of 80 hollow masonry walls, with varying effective height to thickness ratio, eccentricity, and inclusion of initial geometric imperfection. Numerical results are used to determine when the inclusion of geometric imperfections impacts numerical predictions, and to determine wall failure modes for various parametric combinations. The model is also used to discuss adjustments to clauses in CSA S304-14 related to minimum primary moment and hollow masonry wall axial strength.

description: Marker-based Optical Motion Capture (OMC) systems and associated musculoskeletal (MSK) modelling predictions offer non-invasively obtainable insights into in vivo joint and muscle loading, aiding clinical decision-making. However, an OMC system is lab-based, expensive, and requires a line of sight. Inertial Motion Capture (IMC) systems are widely-used alternatives, which are portable, user-friendly, and relatively low-cost, although with lesser accuracy. Irrespective of the choice of motion capture technique, one needs to use an MSK model to obtain the kinematic and kinetic outputs, which is a computationally expensive tool increasingly well approximated by machine learning (ML) methods. Here, we present an ML approach to map experimentally recorded IMC data to the human upper-extremity MSK model outputs computed from ('gold standard') OMC input data. Essentially, we aim to predict higher-quality MSK outputs from the much easier-to-obtain IMC data. We use OMC and IMC data simultaneously collected for the same subjects to train different ML architectures that predict OMC-driven MSK outputs from IMC measurements. In particular, we employed various neural network (NN) architectures, such as Feed-Forward Neural Networks (FFNNs) and Recurrent Neural Networks (RNNs) (vanilla, Long Short-Term Memory, and Gated Recurrent Unit) and searched for the best-fit model through an exhaustive search in the hyperparameters space in both subject-exposed (SE) & subject-naive (SN) settings. We observed a comparable performance for both FFNN & RNN models, which have a high degree of agreement (ravg, SE, FFNN = 0.90+/-0.19, ravg, SE, RNN = 0.89+/-0.17, ravg, SN, FFNN = 0.84+/-0.23, & ravg, SN, RNN = 0.78+/-0.23) with the desired OMC-driven MSK estimates for held-out test data. Mapping IMC inputs to OMC-driven MSK outputs using ML models could be instrumental in transitioning MSK modelling from 'lab to field'.
