description: Numerous solutions to solve existing problems of pedestrian navigation have been proposed in the last decade by both industrial and academic researchers. However, to date, there are still major challenges for a pedestrian navigation system (PNS) to operate continuously, robustly, and seamlessly in all indoor/outdoor environments. Since the Global Navigation Satellite System (GNSS) is reliable under most outdoor environments, novel methods for pedestrian indoor navigation applications through integrating different navigation techniques and systems were proposed in this thesis. A PNS architecture based on a single device was first introduced, integrating the inertial navigation system (INS) mechanization, the pedestrian dead reckoning (PDR) mechanization, and the WiFi fingerprinting positioning method. Experimental evaluation showed that the proposed WiFi/PDR/INS algorithm not only tracks closest to the actual pedestrian walking trajectories but also provides the navigation results with good continuity. When multiple PNSs are used simultaneously by a specific user, novel information fusion methods for multiple PNSs integration to enhance the performance of each PNS are proposed. A nonlinear inequality distance constraint between any two PNSs was mathematically formulated. A novel filtering technique named the state-constrained Kalman filter (KF) was used to explore such a constraint information, further diminishing the positioning errors of each PNS. Two different approaches based on the state-constrained KF for solving the multiple PNSs integration problem were proposed. The first approach incorporates a soft constraint into a KF to enable the state estimate almost satisfies the constraint rather than strictly satisfies the constraint; the second approach is based on solving a Quadratic Programming (QP) problem to ensure that the state estimate should strictly satisfy the constraint. Simulation studies and field experiments were conducted to assess the two proposed approaches. The results showed that both approaches could well bound the navigation state errors compared with the unconstrained state estimate. However, the performance of the hard constraint approach was better than that of the soft constraint approach when a constraint’s nonlinearity level increased. It is indicated from this research that using motion sensor data from multiple mobile devices could provide more accurate navigation solutions for a pedestrian in all indoor/outdoor environments.

description: The weak itinerant ferromagnetic behavior of Y$_2$Ni$_7$ is investigated through magnetic, transport and calorimetric measurements. The low value of saturation moment, large Rhodes-Wohlfarth ratio, large value of the linear term in heat capacity and Fermi liquid like resistivity behavior with enhanced electron-electron scattering contribution establish firmly the weak itinerant ferromagetic nature of the sample. The critical exponents associated with the paramagnetic to ferromagnetic transition are also investigated from magnetization isotherms using modified Arrott plot, Kouvel-Fisher plot and critical isotherm technique. The more accurate Kouvel-Fisher plot provides the critical exponents to be $β$ = 0.306, $γ$ = 1.401 and $δ$ = 5.578. These values are markedly different from the mean field values and correspond closely to the two dimensional Ising spin system with long range spin spin interaction.

description: We propose a simple scheme to construct composition-dependent interatomic potentials for multicomponent systems that when superposed onto the potentials for the pure elements can reproduce not only the heat of mixing of the solid solution in the entire concentration range but also the energetics of a wider range of configurations including intermetallic phases. We show that an expansion in cluster interactions provides a way to systematically increase the accuracy of the model, and that it is straightforward to generalise this procedure to multicomponent systems. Concentration-dependent interatomic potentials can be built upon almost any type of potential for the pure elements including embedded atom method (EAM), modified EAM, bond-order, and Stillinger-Weber type potentials. In general, composition-dependent N-body terms in the total energy lead to explicit (N+1)-body forces, which potentially renders them computationally expensive. We present an algorithm that overcomes this problem and that can speed up the calculation of the forces for composition-dependent pair potentials in such a way as to make them computationally comparable in efficiency and scaling behaviour to standard EAM potentials. We also discuss the implementation in Monte-Carlo simulations. Finally, we exemplarily review the composition-dependent EAM model for the Fe-Cr system [PRL 95, 075702 (2005)].

description: Studies have shown that though there is a recent push to include computational thinking and coding in elementary schools, many elementary school teachers have no background in the subject and would require training to effectively teach computational thinking to their students. In this thesis, the development of a framework to train elementary school teachers and students in computational thinking is presented. It is based on a framework for engineering education, and modifies that framework to design and implement creative, cross-curricular activities to teach computational thinking and engineering concepts for students in grades K-6. The activities are also used in a professional development workshop to train teachers in these skills. These activities have positive impacts on perceptions of computational thinking for both elementary school teachers and their students, as evaluated by surveys and interview responses. As well, teachers felt more confident in their ability to implement similar activities in their classrooms.

description: This paper applies I.M. Gelfand's distinction between adequate and non-adequate use of mathematical language in different contexts to the newly opened window of model-based measurements of intracellular dynamics. The specifics of geometry and dynamics on the mesoscale of cell physiology are elaborated - in contrast to the familiar Newtonian mechanics and the more recent, but by now also rather well established quantum field theories. Examples are given originating from the systems biology of insulin secreting pancreatic beta-cells and the mathematical challenges of an envisioned non-invasive control of magnetic nanoparticles.

description: Maximal aerobic capacity (VO2max) is considered the reference for determining an individual’s level of fitness. To measure VO2max, a subject must perform an incremental fitness test while wearing a facemask that samples expired gases and ventilation rates. In horses, the practicality of VO2max testing in the field is limited by mask design, specifically due to impedance of airflow. The trajectory of airflow as it enters and exits the nasal passage must therefore be fully understood in order to build a functional mask. Computational fluid dynamics (CFD) was used to model flow patterns and pressure changes at various rates in the equine nasal passage. Results were validated with experimental data obtained from a 3D printed model of a horse head. Preliminary mask designs were investigated using CFD and a current design was tested using the 3D printed model. Data was also collected on sport horses in the field.
Navigating marine ecosystem services and values

Publisher: name: University of British Columbia

description: It is broadly recognized that local knowledge and values should play a prominent role in natural resource decision-making. This research was based on the concept of ecosystem services (ES), which are the ecological processes through which nature provides benefits to people. A primary methodological research goal was to test an interview protocol to solicit the verbal articulation, spatial identification and a quantitative measure of local monetary values, non-monetary values and threat intensities associated with marine ES. This research identified and characterized a wide range of ways in which people value marine ecosystems in the Regional District of Mount Waddington in British Columbia, Canada to inform an ongoing marine spatial planning process. A total of 30 semi-structured interviews were conducted based on non-proportional quota sampling to target interviewees from across the district who have a variety of marine-related occupations. The interview protocol was successful in eliciting emotive expressions of the intangible benefits and values pertaining to ES. All interviewees verbally identified these benefits and values, but some (30%) refused to assign quantified non-monetary value to specific locations and others (16%) chose not to identify specific locations of non-monetary importance. Given that the spatial quantification of non-monetary values was not broadly acceptable, it is recommended that these research findings and methods complement deliberative processes to enable decision makers to more fully consider stakeholder’s non-monetary values and threats associated with ES. When explaining values and threats across the seascape, respondents bundled various services, benefits, and values associated with ecosystems. For articulating specific values, many used metaphors quite different form the implicit ES metaphor of nature as service provider. This protocol did not fully crowd out these alternative metaphors. Based on the spatial analysis, there was significant overlap among all three pair-wise comparisons of monetary values, non-monetary values, and threat intensity values. People tended to assign greater monetary and non-monetary value closest to inhabited locations. Employment in salmon aquaculture, the most divisive marine issue in the region, correlated with the perception that the ocean does not face environmental threat associated with this industry.

description: Located at the intersection of urban development and civic arts governance, an experimental arts space is diversely represented by its three vested groups. For Calgary Municipal Land Corp (CMLC), the Seafood Market is a grassroots marketing campaign; for Calgary Arts Development Authority (CADA), the repurposed building is an experiment in arts space governance; and for artists the donated space is a temporarily affordable haven at the centre of a ‘creative city’ make-over. Helping to identify the underlying motives and methods of these narrators are Bourdieu’s capitals theory and Lefebrve’s notions of spatial practices. By combining a narrative research approach for data analysis with an arts-based research text, this communications case study demonstrates the conscription of artists as characters in the dominant narrative of urban gentrification and the influences limiting their active participation in complicating that narrative.

description: Assessment of nanoparticle distribution in the vasculature is important for determining drug delivery, molecular imaging efficacy, and risk profiles. Even though most medical nanoparticle applications require a vascular administration, factors affecting nanoparticle association with vessel walls in the presence of fluid forces are poorly understood. We evaluated the effect of fluid flow on the distribution of 200 nm carboxylate-coated polystyrene nanoparticles in flow-exposed endothelial cell cultures and zebrafish embryos. We combined confocal imaging of nanoparticle injected transgenic zebrafish, 3D modeling, and computational fluid dynamics to assess nanoparticle distribution under flow. Highest nanoparticle localization occurred in regions of disturbed flow and low shear stress found at branch points and downstream of bumps and curves in the zebrafish vasculature. Similar findings were obtained in human endothelial cells in vitro. Overall, fluid shear stress magnitude, flow disturbances, and flow-induced changes in endothelial physiology contribute to the vascular localization of nanoparticles.

description: Inorganic mercury (Hg2+) and cadmium (Cd2+) are toxic heavy metals linked to the etiology of cancer and diabetes. The binding affinity of these metals to biomimetic erythrocyte (RBC) membranes and their influence on membrane phase transition (Tm) were investigated using isothermal titration calorimetry (ITC) and dynamic light scattering (DLS), respectively. Hg2+ bound plasmalogen phospholipids (PL) 350-2300 times stronger than diacyl lipids. Furthermore, Hg2+ increased the Tm of phosphatidylcholine plasmalogen (PCplas) indicating tighter lipid packing. In contrast, Cd2+ exclusively targeted negatively charged phosphatidylserine (PS) and increased its Tm. Cd2+ presence in metal mixtures (1:1 Hg2+:Cd2+) enhanced Hg binding to diacyl PL’s and significantly increased the Tm of PCplas. Finally, 1 mM Hg2+ and Cd2+ bound rabbit erythrocytes with high affinity and induced echinocyte and RBC vesiculation as visualized by microscopy. The results obtained enhance our understanding of metal-lipid binding and ultimately metal-induced RBC toxicity in mammals.

description: In this paper we introduce a new way to deal with Grid portals referring to our implementation. L-GRID is a light portal to access the EGEE/EGI Grid infrastructure via Web, allowing users to submit their jobs from a common Web browser in a few minutes, without any knowledge about the Grid infrastructure. It provides the control over the complete lifecycle of a Grid Job, from its submission and status monitoring, to the output retrieval. The system, implemented as client-server architecture, is based on the Globus Grid middleware. The client side application is based on a java applet; the server relies on a Globus User Interface. There is no need of user registration on the server side, and the user needs only his own X.509 personal certificate. The system is user-friendly, secure (it uses SSL protocol, mechanism for dynamic delegation and identity creation in public key infrastructures), highly customizable, open source, and easy to install. The X.509 personal certificate does not get out from the local machine. It allows to reduce the time spent for the job submission, granting at the same time a higher efficiency and a better security level in proxy delegation and management.

description: Introduction:
 Uncomplicated placement of peritoneal dialysis catheter (Tenckhoff catheter) is one of the key factors for successful peritoneal dialysis in patient with end stage renal disease (ESRD). Majority of catheter placement in Hospital Raja Perempuan Zainab ll (HRPZ ll) were done by nephrologists either by percutaneous or peritoneoscopy method. The aim of this study is to compare the catheter outcome and 1 year survival rate between both methods. Methods:
 Data were collected retrospectively on all ESRD patients having Tenckhoff catheters inserted by nephrologists in our centre between January 2015 and June 2018 and fulfilled the study criteria. Statistical analysis executed with SPSS version 21. Results:
 A total of 115 patients fulfilled the selection criteria. Sixty-seven catheters were placed percutaneously and 48 were placed peritoneoscopically. Seven patients developed events within 30 days post Tenckhoff catheter insertion (percutaneous versus peritoneoscopy group; 4(6.0%) versus 3 (6.3%) respectively, p-value=1.000). Within one year post catheter insertion, a total of 51 catheters were removed mainly due to peritonitis (18(35%) versus 9(18%), p-value=0.311) followed by malfunction (9(18%) versus 13(25%), p-value=0.066) and exit site infection (2(4%) versus 0(0%), p-value=0.229). The 1-year survival rate for both percutaneous method and peritoneoscopy method were 56.7% (95% CI: 44.0%, 68.8%) and 54.2% (95% CI: 39.2%, 68.6%) respectively.
 Conclusion:
 There is no significant difference between percutaneous and peritoneoscopy method of Tenckhoff catheter placement with regard to infectious and mechanical complications as well as 1-year catheter survival rate. Disclaimer: Abstract text might vary slightly from what is displayed in the e-poster.

description: A strong magnetic field applied along the growth direction of a semiconductor quantum well gives rise to a spectrum of discrete energy states, the Landau levels. By combining quantum engineering of a quantum cascade structure with a static magnetic field, we can selectively inject electrons into the excited Landau level of a quantum well and realize a tunable surface emitting device based on cyclotron emission. By applying the appropriate magnetic field between 0 and 12 T, we demonstrate emission from a single device over a wide range of frequencies (1-2 THz and 3-5 THz).

description: With a wide interest in the effects of climate change on forest fire regimes, there has been a proliferation of studies analyzing the past fire weather trends using daily surface weather stations data. However, not all studies take account of such data's inherent inconsistencies (inhomogeneities) from non-climatic influences. This study shows their influence on the linear trends in the Canadian Forest Fire Weather Index System (CFFWIS) codes, commonly used as a fire weather proxies worldwide. Trend significance of up to 50\% of the Canadian weather stations considered was affected if computed using the homogenized data instead of the raw inhomogeneous records. Duff Moisture Code (DMC) is the most resistant to weather record inhomogeneities, followed by the Drought Code (DC). Monthly Drought Code (MDC) is recommended as an optimal fire weather proxy for long term analysis, as monthly data homogenization produces results that are superior to daily data homogenization.

description: Although doctoral student attrition and persistence have been researched previously, attrition rates remain high and continue to be a cause for concern. This mixed methods study employed an explanatory sequential design to learn about the decision-making experiences of five former Doctor of Education (EdD) students from Canadian universities who left their academic programs prior to graduation. In the first phase of the study, quantitative data were collected through an online questionnaire. Interviews were conducted in the second, qualitative, phase to explain and to deepen the understanding of the quantitative results. In Phase One, finances, employment or job responsibilities, inability to complete program requirements within deadlines, and family responsibilities were found to have contributed to participants’ decisions to leave their EdD programs without graduating. During their interviews, participants expanded on their questionnaire responses. All participants identified a defining moment when they knew they would be leaving their EdD programs, and although participants expressed regret and disappointment at not graduating, all cited positive aspects to having been enrolled in their doctoral programs, and some spoke about the possibility of returning to doctoral studies in the future. The quantitative and qualitative findings from the two phases of the study are discussed within the context of previous research. Challenges with participant recruitment for this study are examined, and implications and recommendations are presented for current and future EdD students, EdD supervisors and supervisory committee members, and other leaders involved in the delivery of EdD programs.

description: Fermi National Accelerator Laboratory is constructing a superconducting 1.3 GHz cryomodule test facility located at the New Muon Lab building. The facility will be used for testing and validating cryomodule designs as well as support systems. For the initial phase of the project, a single Type III plus 1.3 GHz cryomodule will be cooled and tested using a single Tevatron style standalone refrigerator. Subsequent phases involve testing as many as two full RF units consisting of up to six 1.3 GHz cryomodules with the addition of a new cryogenic plant. The cryogenic infrastructure consists of the refrigerator system, cryogenic distribution system as well as an ambient temperature pumping system to achieve 2 K operations with supporting purification systems. A discussion of the available capacity for the various phases versus the proposed heat loads is included as well as commissioning results and testing schedule. This paper describes the plans, status and challenges of this initial phase of the New Muon Lab cryogenic system.

Reír en tiempos de guerra: un estudio aproximativo del humor y los chistes en el Cantar de Mio Cid
Creators: name: Rincones-Guerra, Mario Alexander
Publisher: name: Graduate Studies
Year: 2013
Subjects: subject: Literature--Medieval
subject: Mio Cid

description: The research presented in this thesis deals with the first extensive narrative work in Spanish literature, that is, the Cantar de Mio Cid (XII - XIII centuries). The research interest focuses on the jokes and humorous language found in the work. The study focuses on an in-depth analysis of these same elements, to date largely unexplored, or generally carried out superficially. This may be a result of the controversy that concerns their true presence in the Cantar. However, the thesis and arguments presented herein argue the validity of the methodological approach; that is, regardless of the conscious or unconscious inclusion of these elements in the Cantar, the fact remains that they exist in the text and are closely related to burlesque humour. Those jokes and humorous language have a clear proselytizing and warlike function and intent, and include the subtle fostering of a certain hatred and anti-Semitism latent in the period. The arguments and analysis presented in the course of this work are corroborated by the results of a textual, historical, and sociocultural interpretation of the Cantar de Mio Cid, as well as the theory of jokes, according to Sigmund Freud.

description: I present my analysis of the extended emission (XE) polarisation data from the Canadian Galactic Plane Survey. I used this dataset to determine Rotation Measures (RMs) with the aim of studying the Galactic magnetic field (GMF) structure. I have shown that RMs of the XE do contain useful information, despite predicted difficulties with this kind of dataset. I have found evidence that the large-scale field reversal between the local arm and the Sagittarius arm is not strictly perpendicular to the Galactic plane as previously thought, but has some component within the Galactic disk. This geometry lends credibility to a model of the GMF similar to the Parker spiral Solar magnetic field, an idea proposed in 1982 but rejected shortly thereafter on the grounds of incompatibility with observations available at the time. I have created a Galactic scale version of this model of the magnetic field, constrained by the XE RMs.

description: An analysis of conversations with bloggers in both focus groups and interviews as well as a decade-long observation of blogging culture informs this exploration of the ways in which bloggers discursively construct value, and the contingencies of these constructions. The goal was to examine which characteristics and behaviors emerged as privileged and valued and those which were not, extrapolating these visions of value to broader social and cultural contexts where self-documentation and public presentations of self via social media are increasingly prevalent. The participants in this study took up multiple, complex and often intersecting discourses of value. Value operated in understandings of textual conventions and standards; of the norms and potential of blogging as a technology of the self (Foucault, 1988); as social and cultural capital (Bourdieu, 1986) and subcultural capital (Thornton, 1997); in the ‘scene’ (Irwin, 1977) of blogging culture; and as economic value. In this context, tensions emerge where constructions of authenticity operate as both hallmarks of independence and strategies for monetization and professional progress; and the individual quest for meaning and self-care is situated in a cultural context where usefulness (to others) and validation (from others) often shape visions of value.

description: We have searched ~8200 sq. degs for high proper motion (~0.5-2.7"/year) T dwarfs by combining first-epoch data from the Pan-STARRS1 (PS1) 3-Pi Survey, the 2MASS All-Sky Point Source Catalog, and the WISE Preliminary Data Release. We identified two high proper motion objects with the very red (W1-W2) colors characteristic of T dwarfs, one being the known T7.5 dwarf GJ 570D. Near-IR spectroscopy of the other object (PSO J043.5+02 = WISEP J0254+0223) reveals a spectral type of T8, leading to a photometric distance of 7.2+/-0.7 pc. The 2.56"/yr proper motion of PSO J043.5+02 is the second highest among field T dwarfs, corresponding to an tangential velocity of 87+/-8 km/s. According to the Besancon galaxy model, this velocity indicates its galactic membership is probably in the thin disk, with the thick disk an unlikely possibility. Such membership is in accord with the near-IR spectrum, which points to a surface gravity (age) and metallicity typical of the field population. We combine 2MASS, SDSS, WISE, and PS1 astrometry to derive a preliminary parallax of 171+/-45 mas (5.8{+2.0}{-1.2} pc), the first such measurement using PS1 data. The proximity and brightness of PSO J043+02 will facilitate future characterization of its atmosphere, variability, multiplicity, distance, and kinematics. The modest number of candidates from our search suggests that the immediate (~10 pc) solar neighborhood does not contain a large reservoir of undiscovered T dwarfs earlier than about T8.

description: We present the dust properties and star-formation histories of local submillimetre-selected galaxies in Herschel-ATLAS, classified by optical morphology. The early-type galaxies (ETGs) that are detected contain as much dust as typical spirals, and form a unique sample that has been blindly selected at submillimetre wavelengths. Comparing H-ATLAS galaxies to a control sample of optically selected galaxies, we find 5.5% of luminous ETGs are detected in H-ATLAS. The H-ATLAS ETGs contain a significant mass of cold dust: the mean dust mass is 5.5x10^7 Msun, with individual galaxies ranging from 9x10^5-4x10^8 Msun. This is comparable to that of spirals in our sample, and is an order of magnitude more dust than that found for the control ETGs, which have a median dust mass inferred from stacking of (0.8-4.0)x10^6 Msun. The ETGs detected in H-ATLAS have bluer NUV-r colours, higher specific star-formation rates and younger stellar populations than ETGs which are optically selected, and may be transitioning from the blue cloud to the red sequence. We also find that H-ATLAS and control ETGs inhabit similar low-density environments. We conclude that the dust in H-ATLAS and control ETGs cannot be solely from stellar sources, and a large contribution from dust formed in the ISM or external sources is required. Alternatively, dust destruction may not be as efficient as predicted. We also explore the properties of the most passive spiral galaxies in our sample with SSFR<10^-11/yr. We find these passive spirals have lower dust-to-stellar mass ratios, higher stellar masses and older stellar population ages than normal spirals. The passive spirals inhabit low density environments similar to those of the normal spiral galaxies in our sample. This shows that the processes which turn spirals passive do not occur solely in the intermediate density environments of group and cluster outskirts. (Abridged)

description: Various and different methods can be used to produce high-resolution multispectral images from high-resolution panchromatic image (PAN) and low-resolution multispectral images (MS), mostly on the pixel level. However, the jury is still out on the benefits of a fused image compared to its original images. There is also a lack of measures for assessing the objective quality of the spatial resolution for the fusion methods. Therefore, an objective quality of the spatial resolution assessment for fusion images is required. So, this study attempts to develop a new qualitative assessment to evaluate the spatial quality of the pan sharpened images by many spatial quality metrics. Also, this paper deals with a comparison of various image fusion techniques based on pixel and feature fusion techniques.
Mechanical behavior of woven fabric composites under meso-level uncertainties : modeling and sensitivity analysis
Creators: name: Komeili, Mojtaba

description: Unit cell modeling of the woven fabric composites is a strong tool for studying fabric behavior at meso-level. Among the suggested methods the three-dimensional finite element analysis is found to be promising and of greater interest to researchers in the field. However, due to the multi-scale nature and particular behavior of fibrous yarns, numerical procedures applicable to woven fabrics differ from conventional finite element routines. Moreover, from a practical point of view, most of the models in the literature focus on the ideal unit cells and excludes the meso-level uncertainty factors. On the other hand, experimental measurements indicate non-repeatability of test data which is a result of embedded inherent uncertainties. In this study, a finite element model capable of defining the representative volume element of a plain weave under homogenous loading has been created. Because of particular behavior of dry fabrics, a special constitutive material behaviour is defined via user-defined subroutines, which links to the solver of a finite element package (Abaqus). Material properties of yarns for dry glass fabrics are extracted by fitting their numerical responses to results of experiments. Subsequently, geometrical and material meso-level uncertainty factors are studied separately using two-level factorial designs. The output of runs are inserted into a commercial design package (Design Expert) for producing results in terms of probability plots, effects and percentage contribution of each factor and their interactions. Result shows that depending on the loading type, there are factors that show significant contribution toward the final response, whereas others are quite negligible. More elaboration on the design results provides informative conclusions regarding modeling of unit cells, as well as their behavior during different loading steps. These conclusions can be used in more comprehensive unit-cell homogenization formulations, as well as for defining appropriate tolerances for meso-level defects in woven fabric composites.

description: Because of their unique electrical properties, carbon nanotubes (CNTs), particularly the single-walled carbon nanotubes (SWCNTs), have shown potential applications in electronics. In this study, by controlling their alignments under varied electric fields, SWCNTs were used to prepare microelectrode devices, which were examined and show low-pass filtering harmonic responses. By analyzing the SWCNT-based devices (vs. bare-chip), equivalent circuit models were created to understand these devices and the mechanism of their filtering performance. After a series of simplification and optimization, a final model was obtained and a hypothesis was proposed to explain the relationships between the CNT structures and the corresponding electrical properties. The resulted model was verified about its predictability to the filtering performance of CNT-based devices. In addition, similar devices were fabricated with two types of Rosette nanotubes and were then analyzed regarding their electric properties, confirming its effectiveness of the methodology that was used for the CNT-based devices.

description: We study the time evolution of ultra-cold atoms in an accelerated optical lattice. For a Bose- Einstein condensate with a narrow quasi-momentum distribution in a shallow optical lattice the decay of the survival probability in the ground band has a step-like structure. In this regime we establish a connection between the wave function renormalization parameter Z introduced in [Phys. Rev. Lett. 86, 2699 (2001)] to characterize non-exponential decay and the phenomenon of resonantly enhanced tunneling, where the decay rate is peaked for particular values of the lattice depth and the accelerating force.

Material examined (N=2). 1m, 1f, 06/VI/2000, 13°52’37”S / 38°57’11”W (MZUESC #48).
Distribution. Western Atlantic – Brazil (from Ceará to Bahia) (Melo 1996).
Ecological notes. On calcareous algae bottoms, from 20 to 50 m (Melo 1996).
Previous records in Bahia. Gomes Corrêa (1972) (as P. r i i s e i), Barreto et al. (1993), Almeida et al. (2003), Coelho (2006).
Remarks. Gomes Corrêa (1972) recorded P. riisei from Abrolhos Archipelago, southern Bahia. Nevertheless, the material examined by him, deposited in the Crustacea Collection of the Museu Nacional in Rio de Janeiro is not P. r i i s e i, but P. brasiliensis, as verified by one of us (P. A. Coelho). Abrolhos is the southern range known for this species. Almeida et al. (2003) and Coelho (2006) reported the occurrence of P. brasiliensis in Camamu Bay.

description: The primary aim of this study was to evaluate the effects of ACL injury on neuromuscular function in elite alpine ski racers, and to monitor skiers throughout the return to sport transition. In Chapter 2 a narrative review of the literature was performed on ACL injury, ACL re-injury, and return to sport after ACL injury in ski racing. In Chapter 3, a new test of inter-limb functional asymmetry was used to evaluate alpine ski racers with/without ACL reconstruction (ACLR). Despite a full return to competition, ACLR ski racers demonstrated elevated inter-limb functional asymmetries that were correlated with lower limb muscle mass asymmetry. In Chapter 4, hamstring/quadriceps strength ratios were measured in ski racers with/without ACLR. ACLR ski racers displayed significant hamstring/quadriceps strength deficits in the ACLR limb compared to the contralateral limb and the limb average of non-injured skiers. In Chapter 5, the functional lower-limb asymmetry test introduced in Chapter 3 was used to evaluate the acute effects of a fatiguing jump protocol on asymmetry and hamstring/quadriceps muscle activity in ski racers with/without ACLR. The ACLR skiers displayed systematic inter-limb functional asymmetries. ACLR skiers displayed reduced quadriceps muscle activity at takeoff in the surgical limb. Both the ACLR group and non-injured controls became quadriceps dominant with fatigue. Quadriceps muscle activity increased while hamstring muscle activity decreased. Notably, this was found in the pre-landing phase. In Chapter 6, primary ACLR operative reports from 28 skiers were analyzed to evaluate the associated pathology including multi-ligament injury, meniscal tears and chondral lesions. Operative reports from future surgeries were analyzed to evaluate the injury progression. At the time of primary ACLR, there was a higher proportion of chondral lesions in the lateral compartment compared to the medial compartment, and complex meniscal tears compared to one-dimensional tears. At the time point of future surgery, a significant proportion of skiers showed a worsening of chondral lesions, including half of the skiers presenting with Grade 3 or Grade 4 lesions. Functional asymmetry was also evaluated at various time points following primary ACLR. Nearly two years were required for functional asymmetry indices to reach values comparable to those of non-injured ski racers.
