description: Multi-adjoint logic programming is a general framework with interesting features, which involves other positive logic programming frameworks such as monotonic and residuated logic programming, generalized annotated logic programs, fuzzy logic programming and possibilistic logic programming. One of the most interesting extensions of this framework is the possibility of considering a negation operator in the logic programs, which will improve its flexibility and the range of real applications.
 This paper introduces multi-adjoint normal logic programming, which is an extension of multi-adjoint logic programming including a negation operator in the underlying lattice. Beside the introduction of the syntax and semantics of this paradigm, we will provide sufficient conditions for the existence of stable models defined on a convex compact set of a euclidean space. Finally, we will consider a particular algebraic structure in which sufficient conditions can be given in order to ensure the unicity of stable models of multi-adjoint normal logic programs.
Performing the nation at the frontier : Filipino immigration and settlement in Whitehorse, Yukon
Creators: name: Johnson, Kelsey Mae
Publisher: name: University of British Columbia
Year: 2015

description: Over the past decade, Whitehorse, Yukon has emerged as a prominent site of settlement for Filipino newcomers to Canada. The phenomenon largely results from the implementation of new immigration policy in Yukon (starting in 2007) combined with regional economic growth, particularly in the mining sector. On the surface, immigration to Yukon - ostensibly ‘employer driven,’ with Filipino newcomers primarily finding employment in the service sector - bears resemblances to trends observed elsewhere in Canada. Yet the service sector Filipino workers who increasingly feature in the Yukon’s economy do so as permanent, not temporary, immigrants with the right to settle in Canada. This thesis explores the implications of this dynamic, situating it at the broader intersection of immigration and settler colonialism. I demonstrate how new narratives of northern settlement are enrolled in nation-building discourses of multiculturalism that circulate in and about Yukon. I stress how policy discourses support the essentialization of First Nations and Filipino histories. I also argue that state policies locate immigrants and local Indigenous peoples in competitive labor dynamics. In effect, Yukon’s immigration policy demonstrates how the governing of difference also involves processes of governing by difference – infusing performances of national belonging with powerful state imperatives.

Multi-degree of freedom position sensor for planar motors
Creators: name: Maguire, Keir
Publisher: name: University of British Columbia
Year: 2016

description: This thesis presents the development and verification of a multi-degree of freedom (DOF), non-contact position sensor for a magnetically levitated planar motor. Planar motors are intended to replace X-Y stages in various manufacturing processes resulting in higher accuracy, higher speed, and no friction. To obtain position feedback, previous planar motors have used laser interferometers, planar encoders, stereo vision, capacitive sensors, and Hall sensor arrays. For applications requiring micrometre-level precision, Hall sensor arrays are cost-effective, absolute, high bandwidth, can be integrated into the stator, and are capable of sensing multiple movers in 6-DOF over large stroke and rotation. However, previous Hall sensor arrays suffered from excessive error, low bandwidth, absolute position only within one pitch of the magnet array, modifications to the mover, lack of 6-DOF or multi-mover capability, or limited range. A 2-D Hall sensor array was developed. There are three sensors per wavelength of the magnetic field, which decouples sensor outputs for orthogonal 1-D Halbach magnet arrays. The position in 2-DOF, X and Z, is calculated for a 1-D Halbach array. The position in 6-DOF can be calculated for a planar motor mover composed of four orthogonal Halbach arrays. This sensor solution measures absolute position and is high bandwidth, multi-mover capable, and scalable with stroke. A prototype was designed, consisting of a Hall sensor array, summing amplifiers, and signal processing electronics. The prototype was tested in 2-DOF using a CNC to move a Halbach array to discrete points. Position error is approximately 200 µm peak to peak; however, the error is periodic and can be compensated. Resolution is 5 µm. Due to redundancy and averaging, improved accuracy and resolution is expected for 6-DOF sensing of the planar motor. Variation in sensor gain is a common cause of error in previous Hall sensor arrays. Previous Hall sensor arrays have only achieved good accuracy by using laser interferometers for error mapping or individual differential amplifiers to control each sensor’s gain. A sensor sorting setup was designed, built, and used to sort more than 12,000 sensors based on gain. The sorted sensors can be used for a sensor array with micrometre-level accuracy.
Disordered eating and sexuality in women
Creators: name: Dunkley, Cara R.
Publisher: name: University of British Columbia
Year: 2015

description: Background: There has long been a proposed clinical link between sexuality and eating disorders; however, little empirical evidence exists regarding this relationship. The limited body of research on sexuality in eating disorders supports the occurrence of considerable sexual concerns. The aim of the present study was to expand on the dearth of empirical literature exploring altered sexuality in relation to disordered eating. Study 1 examines disordered eating in relation to sexual function and sexual insecurities. Study 2 examines the association between eating disorder symptoms in relation to genital pain and sexual distress. Study 3 examines the mediational role of personality and mood on the relation between eating pathology and genital pain. Methods: Undergraduate female UBC students completed a series of online questionnaires assessing eating habits, sexual functioning, sexual insecurities, personality, and mood. Two rounds of data collection were conducted, the first occurring from December of 2013 to April of 2014 (n = 321), the second between May of 2014 and April of 2015 (n = 854). Results: Several domains of sexual dysfunction were associated with disordered eating symptom severity, particularly genital pain and sexual distress. Mean differences in eating disorder symptoms emerged in women with clinically significant genital pain compared to those without pain, such that women in the genital pain group reported more eating pathology. Mean differences in genital pain, sexual distress, and sexual insecurities emerged among women categorized as being at elevated, typical, or low eating disorder risk, with those at greater risk reporting greater sexual difficulties. Sexual insecurity variables, as well as personality and characteristics common to individuals with eating disorder pathology, mediated the association between disordered eating and genital pain. Discussion: Sexuality is rarely considered in the context of eating disorder treatment unless a history of sexual abuse is present. The results of this study suggest that sexual functioning difficulties should be addressed during eating disorder care. Findings also indicate that women with eating disorders would benefit from treatments targeting sexual insecurities and personality gestures associated with eating pathology in addition to sexual function.

description: In our hierarchical structure-formation paradigm, the observed morphological evolution of massive galaxies -- from rotationally-supported discs to dispersion-dominated spheroids -- is largely explained via galaxy merging. However, since mergers are likely to destroy discs, and the most massive galaxies have the richest merger histories, it is surprising that any discs exist at all at the highest stellar masses. Recent theoretical work by our group has used a cosmological, hydrodynamical simulation to suggest that extremely massive (M* > 10^11.4 MSun) discs form primarily via minor mergers between spheroids and gas-rich satellites, which create new rotational stellar components and leave discs as remnants. Here, we use UV-optical and HI data of massive galaxies, from the SDSS, GALEX, DECaLS and ALFALFA surveys, to test these theoretical predictions. Observed massive discs account for ~13% of massive galaxies, in good agreement with theory (~11%). ~64% of the observed massive discs exhibit tidal features, which are likely to indicate recent minor mergers, in the deep DECaLS images (compared to ~60% in their simulated counterparts). The incidence of these features is at least four times higher than in low-mass discs, suggesting that, as predicted, minor mergers play a significant (and outsized) role in the formation of these systems. The empirical star-formation rates agree well with theoretical predictions and, for a small galaxy sample with HI detections, the HI masses and fractions are consistent with the range predicted by the simulation. The good agreement between theory and observations indicates that extremely massive discs are indeed remnants of recent minor mergers between spheroids and gas-rich satellites.

Distinguishing sensor and system faults for diagnostics and monitoring
Creators: name: Taiebat, Morteza
Publisher: name: University of British Columbia
Year: 2015

description: Automated FDD systems depend entirely on reliability of sensor readings, since they are the monitoring interface of the system. With an unexpected variation in a sensor’s reading from its anticipated values, the challenge is to determine if it is symptom of a fault in the sensor or the monitored system. The ability to identify the source of faults is crucial in the monitoring of a system, as different corrective actions are required in case of sensor or system faults. To address this issue, first, it is clarified that by strict duplication of sensor elements, it is feasible to differentiate between sensor and system faults. However, duplication is not always practical. Hence, by aiming to identify the minimum degree of sensor redundancy, a priori knowledge of physical relationships (functional redundancy) between monitored variables is used to check the credibility of existing sensor observations via Analytical Computational Substitutions (ACS). In the proposed methodology for a certain class of systems, the system variables are modeled with serially connected causal network. Then the concept of Moving Monitoring Window (MMW) is introduced, which covers three nodes at the same time, as it traverses through the nodes of the system in the direction of causality. The Logic Set Unit consists of all system/sensor state possibilities called System Behavioral Modes, which allows decision-making on the health status of sensor or system or a combination. The generalization by deduction reveals that if the number of sensors is greater than 1.5 times of the number of monitored variables, the task of distinguishing between sensor and system faults can be done, as long as serial causality is valid between the monitored variables. Removing any more sensors from this configuration leads to inability to locate the faults, due to the lack of adequate behavioral modes for diagnosis decision. The effectiveness of the approach is verified on a system of interconnected multi reservoirs and control valves.

description: Attribute and size reductions are key issues in formal concept analysis. In this paper, we consider a special kind of equivalence relation to reduce concept lattices, which will be called local congruence. This equivalence relation is based on the notion of congruence on lattices, with the goal of losing as less information as possible and being suitable for the reduction of concept lattices. We analyze how the equivalence classes obtained from a local congruence can be ordered. Moreover, different properties related to the algebraic structure of the whole set of local congruences are also presented. Finally, a procedure to reduce concept lattices by the new weaker notion of congruence is introduced. This procedure can be applied to the classical and fuzzy formal concept analysis frameworks.

description: Formal concept analysis (FCA) is a useful mathematical tool for obtaining information from relational datasets. One of the most interesting research goals in FCA is the selection of the most representative variables of the dataset, which is called attribute reduction. Recently, the attribute reduction mechanism has been complemented with the use of local congruences in order to obtain robust clusters of concepts, which form convex sublattices of the original concept lattice. Since the application of such local congruences modifies the quotient set associated with the attribute reduction, it is fundamental to know how the original context (attributes, objects and relationship) has been modified in order to understand the impact of the application of the local congruence in the attribute reduction.
Water quality management in small to medium sized distribution networks : optimizing chlorine disinfection strategies
Creators: name: Islam, Nilufar
Publisher: name: University of British Columbia
Year: 2015

description: Main objective of this research is to optimize booster chlorination to ensure high quality water in the distribution network (DN). Focus of this research is primarily small to medium sized DNs that lack continuous monitoring, where chlorination is the predominant disinfection practice to maintain acceptable drinking water quality. In this research, new methods and strategies have been proposed to help in selecting location and dosages for booster chlorination, which protects against microbiological contamination and biofilm growth but also limit formation of harmful disinfectant by-products (DBPs), and chlorine related taste & odors issues. This research developed index and risk based schemes to optimize water quality in DNs. Three indices have been proposed: 1) non-compliance potential index (NCP index), 2) modified Canadian Council of Ministries of the Environment Water Quality index (Modified CCME WQI), and 3) intrusion risk potential (IRP). NCP index has been developed to evaluate regulatory violations of DBPs using Bayesian Belief Network. The modified CCME WQI, an extension of commonly accepted CCME WQI, has been developed to evaluate Stage 1 and Stage 2 DBP rules. Risk based index (IRP) has been developed to identify potential intrusion points based on pollutant source, water main characteristics, soil properties, operational and land use factors and population served. Three optimization schemes and algorithms have been proposed to determine the number of booster locations and corresponding dosage levels. Modified CCME WQI has been used to select optimal dosage for booster chlorination using response surface optimization. It uses temporal series data for free residual chlorine (FRC) and converts into an index by maximizing water quality. Later another optimization algorithm has been developed to locate booster stations using FRC and total trihalomethane time series data. This algorithm is called maximum covering location problem, which has been developed using EPANET–MSX programmer’s toolkit integrated with Matlab coding. Third optimization algorithm has been developed to minimize the impacts of contaminant intrusion using booster chlorination. This scheme uses multi-objective genetic algorithm to select both location and dosages for booster chlorination. Proposed methods and strategies have been demonstrated using case studies on City of Kelowna and Quebec City DNs.

Learning periorbital soft tissue motion
Creators: name: Ranjan, Anurag
Publisher: name: University of British Columbia
Year: 2016

description: Human observers tend to pay a lot of attention to the eyes and the surrounding soft tissues. These periorbital soft tissues are associated with subtle and fast motions that convey emotions during facial expressions. Modeling the complex movements of these soft tissues is essential for capturing and reproducing realism in facial animations. In this work, we present a data driven model that can efficiently learn and reproduce the complex motion of the periorbital soft tissues. We develop a system to capture the motion of the eye region using a high frame rate monocular camera. We estimate the high resolution texture of the surrounding eye regions using a Bayesian framework. Our learned model performs well in reproducing various animations of the eyes. We further improve realism by introducing methods to model facial wrinkles.

description: With steadily increasing wind turbine penetration, regulatory standards for grid interconnection are evolving to require that wind generation systems ride-through disturbances such as faults and support the grid during such events. Conventional modifications to the doubly fed induction generation (DFIG) architecture for providing ride-through result in limited control of the turbine shaft and grid current during fault events. A DFIG architecture in which the grid side converter is connected in series as opposed to parallel with the grid connection has shown improved low voltage ride through but poor power processing capabilities. In this paper a unified DFIG wind turbine architecture which employs a parallel grid side rectifier and series grid side converter is presented. The combination of these two converters enables unencumbered power processing and improved voltage disturbance ride through. A dynamic model and control structure for this unified architecture is developed. The operation of the system is illustrated using computer simulations.

description: We consider the fine grading of $sl(n,\mb C)$ induced by tensor product of generalized Pauli matrices in the paper. Based on the classification of maximal diagonalizable subgroups of $PGL(n,\mb C)$ by Havlicek, Patera and Pelantova, we prove that any finite maximal diagonalizable subgroup $K$ of $PGL(n,\mb C)$ is a symplectic abelian group and its Weyl group, which describes the symmetry of the fine grading induced by the action of $K$, is just the isometry group of the symplectic abelian group $K$. For a finite symplectic abelian group, it is also proved that its isometry group is always generated by the transvections contained in it.

description: Discourse parsing is a crucial task in natural language processing that aims to reveal the higher-level relations in a text. Despite growing interest in cross-lingual discourse parsing, challenges persist due to limited parallel data and inconsistencies in the Rhetorical Structure Theory (RST) application across languages and corpora. To address this, we introduce a parallel Russian annotation for the large and diverse English GUM RST corpus. Leveraging recent advances, our end-to-end RST parser achieves state-of-the-art results on both English and Russian corpora. It demonstrates effectiveness in both monolingual and bilingual settings, successfully transferring even with limited second-language annotation. To the best of our knowledge, this work is the first to evaluate the potential of cross-lingual end-to-end RST parsing on a manually annotated parallel corpus.
Collisional dark matter density profiles around supermassive black holes

description: We solve the spherically symmetric time dependent relativistic Euler equations on a Schwarzschild background space-time for a perfect fluid, where the perfect fluid models the dark matter and the space-time background is that of a non-rotating supermassive black hole. We consider the fluid obeys an ideal gas equation of state as a simple model of dark matter with pressure. Assuming out of equilibrium initial conditions we search for late-time attractor type of solutions, which we found to show a constant accretion rate for the non-zero pressure case, that is, the pressure itself suffices to produce stationary accretion regimes. We then analyze the resulting density profile of such late-time solutions with the function $A/r^κ$. For different values of the adiabatic index we find different slopes of the density profile, and we study such profile in two regions: a region one near the black hole, located from the horizon up to 50$M$ and a region two from $\sim 800M$ up to $\sim 1500M$, which for a black hole of $10^{9}M_{\odot}$ corresponds to $\sim 0.1$pc. The profile depends on the adiabatic index or equivalently on the pressure of the fluid and our findings are as follows: in the near region the density profile shows values of $κ<1.5$ and in the limit of the pressure-less case $κ\rightarrow 1.5$; on the other hand, in region two, the value of $κ<0.3$ in all the cases we studied. If these results are to be applied to the dark matter problem, the conclusion is that, in the limit of pressure-less gas the density profile is cuspy only near the black hole and approaches a non-cuspy profile at bigger scales within 1pc. These results show on the one hand that pressure suffices to provide flat density profiles of dark matter and on the other hand show that the presence of a central black hole does not distort the density profile of dark matter at scales of 0.1pc.

Sustainable transport safety : ComPASS case study of a community U-PASS in Kelowna, British Columbia
Creators: name: Morrison, Ellen Samantha
Publisher: name: University of British Columbia
Year: 2015

description: One way to reduce the negative impacts of automobile-dependency is to encourage active transportation (AT), such as walking, biking, and transit, while reducing vehicle use. One initiative proven to reduce vehicle use is the Community U-Pass (ComPASS) concept demonstrated through Boulder, Colorado’s Neighbourhood Eco (NECO) Pass program. ComPASS is a universal community transportation pass (U-Pass) that would provide unlimited access transit passes and other possible components including recreation centre passes, bike tune-ups, merchant incentives, and emergency taxi rides home. The goal of providing a ComPASS to neighbourhoods is to provide an attractive alternative to encourage decreased personal vehicle use in favour of AT modes. This thesis explores the possibility of a ComPASS for the residents of the Glenmore neighbourhood in Kelowna, British Columbia. Two factors motivated this research: 1) an interest in sustainable communities and 2) sustainable transport safety (STS). The objectives of this research were to 1) compare Kelowna to other cities where similar ComPASS programs have been successful, 2) design a ComPASS that would compete with personal vehicle use, and 3) implement a ComPASS pilot program to test the potential of the program in Kelowna. Results suggest that ComPASS could significantly reduce personal vehicle use at a 93.7% confidence level and increase transit use at an 85.7% confidence level. Personal vehicle use could decrease between 6% and 12% amongst ComPASS holders which would translate to a reduction in vehicle kilometres travelled (VKT) per household, resulting in several community-wide benefits. Due to the potential benefits, ComPASS is a recommended tool for the City of Kelowna to implement in efforts to achieve their sustainability goals. Consequently, a three-year permanent ComPASS trial is recommended in the Phase 2 study area, along with transit improvements. Assuming a participation rate of 59%, 19 of the 32 piloted households would participate in a permanent ComPASS program. Over the three year trial period assuming 19 participating households, there could be 6,052 kg to 12,103 kg reduced greenhouse gas (GHG) emissions, 15 to 30 reduced road injuries, 0.06 to 0.11 reduced road fatalities, and social and government savings of $20,552.26 to $41,104.51.

Furthermore, we prove that quaternionic quantum channels can be simulated by completely positive trace preserving maps on complex matrices. These novel results map all quaternionic quantum processes to algorithms in usual quantum information theory.

Publisher: name: University of British Columbia
Year: 2015

description: This paper analyzes the effects of Canadian institutions on the development, structure, and mandate of the Canadian Radio-Television and Telecommunications Commission as a modern regulatory agency. The research focuses on Canadian institutions of federalism and Westminster parliamentary government in order to identify key CRTC features and outcomes that reflect these institutions. This analysis is developed by beginning with a general overview of the literature regarding the effects of institutions in order to identify the significance according to institutional theory. Further, the rise of regulatory regimes and status of regulatory agencies are detailed in order to give greater context to the CRTC. The evidence suggests that the institutions of both federalism and Westminster parliamentary government have influence on the structure and mandate of the CRTC. The primary conclusion of the research is that the CRTC is an institution of Westminster parliament but it is not an institution of federalism per se; rather, it is an institution that results from efforts to manage the effects of Canadian federalism. The research concludes that institutional analysis of regulatory agencies is a legitimate and viable research area, and suggests several valuable future research pursuits.

description: One of the longstanding issues in numerical relativity is to enable a simulation taking account of microphysical processes (e.g., weak interactions and neutrino cooling). We develop an approximate and explicit scheme in the fully general relativistic framework as a first implementation of the microphysics toward a more realistic and sophisticated modeling. In this paper, we describe in detail a method for implementation of a realistic equation of state, the electron capture and the neutrino cooling in a multidimensional, fully general relativistic code. The procedure is based on the so-called neutrino leakage scheme. To check the validity of the code, we perform a two dimensional (2D) simulation of spherical stellar core collapse. Until the convective activities set in, our results approximately agree, or at least are consistent, with those in the previous so-called state-of-the-art simulations. In particular, the radial profiles of thermodynamical quantities and the time evolution of the neutrino luminosities agree quantitatively. The convection is driven by negative gradients of the entropy per baryon and the electron fraction as in the previous 2D Newtonian simulations. We clarify which gradient is more responsible for the convection. Gravitational waves from the convection are also calculated. We find that the characteristic frequencies of the gravitational-wave spectra are distributed for higher frequencies than those in Newtonian simulations due to the general relativistic effects.

Tools and applications for DNA sequencing in the clinical management of viral infectious diseases : examples from HIV-1 and HCV
Creators: name: Brumme, Chanson Joachim
Publisher: name: University of British Columbia
Year: 2015

description: Combination antiretroviral therapy has transformed Human Immunodeficiency Virus (HIV) infection from what was once a fatal diagnosis to a manageable chronic condition. Similarly, new direct-acting antivirals offer a potential cure for individuals infected with Hepatitis C Virus (HCV). Treatment of these two infectious diseases is now routinely guided by genotypic drug resistance testing: portions of the viral genome are sequenced and analyzed for mutations in order to select drug combinations best suited to treat each individual’s unique viral population. The primary aim of this thesis is to develop new methods to personalize therapies for HIV and HCV using a variety of DNA sequencing technologies. First, manual review of Sanger sequences is highly subjective, leading to potential bias in the detection of resistance mutations in diverse viral populations. Automated sequence analysis software that provides standardization between users and laboratories is presented. Second, HIV treatment in resource-limited settings is compromised by insufficient access to resistance testing. To facilitate individual-level monitoring, a low-cost resistance test, whereby hundreds of samples are simultaneously sequenced on a next-generation instrument, is proposed and validated. Third, novel screening and drug resistance tests are required to assess the efficacy of new antivirals. For example, certain regimens containing the protease inhibitor simeprevir are less effective in treating individuals infected with HCV harboring a common polymorphism. Two independent sequencing assays that test for this polymorphism are described and validated. A secondary aim is to measure HIV evolution under immune and drug selection pressures using these same sequencing methods. The hypothesis that effective treatment suppresses viral replication and retards viral evolution is supported by evidence from longitudinal sequences from patients on antiretroviral therapy. A second study demonstrates limited selection of drug resistance mutations in patients with low-level viremia, supporting the hypothesis that many results from an approved clinical test are false positives. Finally, next-generation sequencing is used to quantify HIV variants in cultured virus in order to measure their relative replicative fitness. This thesis provides evidence that new and existing assays and bioinformatic tools will remain invaluable in the clinical management of HIV and HCV as DNA sequencing technologies continue to evolve.
New and old N=8 superconformal field theories in three dimensions

description: We show that an infinite family of N=6 d=3 superconformal Chern-Simons-matter theories has hidden N=8 superconformal symmetry and hidden parity on the quantum level. This family of theories is different from the one found by Aharony, Bergman, Jafferis and Maldacena, as well as from the theories constructed by Bagger and Lambert, and Gustavsson. We also test several conjectural dualities between BLG theories and ABJ theories by comparing superconformal indices of these theories.

A treatise on highly twisted artificial muscle : thermally driven shape memory alloy yarn and coiled nylon actuators
Creators: name: Kianzad, Soheil
Publisher: name: University of British Columbia
Year: 2015

description: A new perspective in the field of actuators was opened by the demonstration of multiwall carbon nanotube based actuators by Foroughi et al, in 2011. The approach involves applying a high degree of twist to create large torsional actuation in carbon nanotube yarns, and more recently in coiled nylon filaments. In this thesis torsional actuation is further studied in nylon, and extended to shape memory alloys (SMA). Torsional actuation is demonstrated using 25 μm diameter micro strands of shape memory alloy (SMAs) that are twisted together. These form yarns with Young’s modulus of 13.5 GPa in the Martensitic phase and 18 GPa in the Austenite state. In torsion, the SMA yarns show more than 8,000 rpm peak rotational speed with 11 reversible rotations for an 8 cm long yarn. This is observed upon applying 0.47 W/cm electrical input power. Providing more than 5 N.m/kg torque, SMA yarns may be of interest in biomedical and other applications. The mechanical behaviour of coiled nylon actuators is studied by testing elastic modulus and by investigating tensile stroke as a function of temperature. Loads that range from 35 MPa to 155 MPa were applied. For the nylon and the coiling conditions used, active thermal contraction totals 19.5 % when the temperature is raised from -40 ⁰C to 160 ⁰C, with most contraction above the glass transition temperature. Introducing various cooling methods was shown to enable increased rate of actuation up to several Hertz. Nylon coiled actuators potentially provide affordable and viable solutions for driving mechanical devices as recently demonstrated in robotic hands and arms. A new biomimetic arrangement of the nylon actuator is presented that imitates the human pennate muscle in structure, including the ability to vary stiffness by a factor of 9 and to increase isometric force from 19 N to 37 N by recruiting additional fibers.
