description: Background: Physiotherapy research supports the advancement of evidence-based practice and the development of a highly-skilled workforce. This study aims to visualize the highly cited scientific output of Indian physiotherapists from 1999 to 2018. Methods: A descriptive study design was adopted to visualize the highly cited scientific output of Indian physiotherapists using the Web of Science (WoS) database from 1999 to 2018. A search was carried out using the following keywords "((TS=(physiotherapy) OR TS=("physical rehabilitation") OR TS=("physical therapy")) AND AD=(India))Indexes=SCI-EXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, ESCI, CCR-EXPANDED, IC Timespan=1999-2018”. Data collected were analyzed using Incites from WoS and VOSviewer software. Results: A total of 488 articles were published between 1999 and 2018, with a peak of 103 in 2016 with 2419 citations. A decline in publication count was observed after 2016. The journal International Journal of Physiotherapy published the highest number of articles (n=35). Manipal University (n=26) was found to be the most active institution for physiotherapy research in India, as determined by publishing the most articles. Indian physiotherapists published the highest number of research articles in collaboration with US authors (n=24). Conclusion: There is an increasing trend in the scientific output of Indian physiotherapists over the past two decades; however, a decline is observed after 2016. It is recommended that research collaborations across the globe are increased, and scientific output should be improved, leading to a higher number of citations. Future research should explore factors influencing the scientific production of Indian physiotherapists and devise appropriate strategies to attain further improvement.

description: Sources of photon pairs based on the spontaneous parametric down conversion process are commonly used for long distance quantum communication. The key feature for improving the range of transmission is engineering their spectral properties. Following two experimental papers [Opt. Lett., 38, 697 (2013)] and [Opt. Lett., 39, 1481 (2014)] we analytically and numerically analyze the characteristics of a source. It is based on a $β$-barium borate (BBO) crystal cut for type II phase matching at the degenerated frequencies 755 nm $\rightarrow$ 1550 nm + 1550 nm. Our analysis shows a way for full control of spectral correlation within a fiber-coupled photon pair simultaneously with optimal brightness.
Freedom ‘En Français’: The Revolutionary Intellectual and Publication Networks in Québec, France, and Algeria, 1963-1968

description: The 1960s were a turbulent time in leftist politics the world over. This thesis examines the publication networks that facilitated contact and solidarity between leftist radicals in Québec, France, and Algeria. From 1963, immediately after the Algerian War, to 1968, when massive protests kicked off in France, self-proclaimed revolutionary men in these three locations used publications as a means of establishing contact, developing ideas, and translating political experiences from one location to another. In particular, this thesis is interested in understanding how Les Éditions Maspero, a French publishing house, La Révolution Africaine, an Algerian magazine, and Parti Pris, a French Canadian magazine, reveal the remarkably similar conception these individuals held about what their role as revolutionary intellectuals was in 1960s liberation movements. I argue that the idea of the revolutionary intellectuals in these writings was one which was defined by their ability to demystify oppressive structures, share revolutionary ideology through writing, and act out the struggle they envisioned both in their own contexts and around the world. By studying revolutionaries’ writing and the activist work that individuals undertook in order to solidify connections between locations, I highlight the importance of reciprocal intellectual exchange in developing political ideologies in France, Québec, and Algeria.

description: This paper is the third in a series presenting the results of direct numerical integrations of the Fokker-Planck equation for stars orbiting a supermassive black hole (SBH) at the center of a galaxy. The algorithm of Paper II included diffusion coefficients that described the effects of random ("classical") and correlated ("resonant") relaxation. In this paper, the diffusion coefficients of Paper II have been generalized to account for the effects of "anomalous relaxation," the qualitatively different way in which eccentric orbits evolve in the regime of rapid relativistic precession. Two functional forms for the anomalous diffusion coefficients are investigated, based on power-law or exponential modifications of the resonant diffusion coefficients. The parameters defining the modified coefficients are first constrained by comparing the results of Fokker-Planck integrations with previously-published N-body integrations. Steady-state solutions are then obtained via the Fokker-Planck equation for models with properties similar to those of the Milky Way nucleus. Inclusion of anomalous relaxation leads to the formation of less prominent cores than in the case of resonant relaxation alone, due to the lengthening of diffusion timescales for eccentric orbits. Steady-state capture rates of stars by the SBH are found to always be less, by as much as an order of magnitude, than capture rates in the presence of resonant relaxation alone.

description: We argue that an important contributing factor into market inefficiency is the lack of a robust mechanism for the stock price to rise if a company has good earnings, e.g., via buybacks/dividends. Instead, the stock price is prone to volatility due to rather random perception/interpretation of earnings announcements (among other data) by market participants. We present empirical evidence indicating that dividend paying stocks on average are less volatile, even factoring out market cap. We further ponder possible ways of increasing market efficiency via 1) instituting such a mechanism, 2) a taxation scheme that would depend on holding periods, and 3) a universal crossing engine/exchange for mutual and pension funds (and similar long holding horizon vehicles) with no dark pools, 100% transparency, and no advantage for timing orders.

description: The Modified Newtonian Dynamics (MOND) paradigm generically predicts that the external gravitational field in which a system is embedded can produce effects on its internal dynamics. In this communication, we first show that this External Field Effect can significantly improve some galactic rotation curves fits by decreasing the predicted velocities of the external part of the rotation curves. In modified gravity versions of MOND, this External Field Effect also appears in the Solar System and leads to a very good way to constrain the transition function of the theory. A combined analysis of the galactic rotation curves and Solar System constraints (provided by the Cassini spacecraft) rules out several classes of popular MOND transition functions, but leaves others viable. Moreover, we show that LISA Pathfinder will not be able to improve the current constraints on these still viable transition functions.

description: We demonstrate that the magneto-optic-Kerr effect with normal light incidence can be used to obtain quantitative optical measurements of both components of spin-orbit-induced torque (both the antidamping and effective-field components) in heavy-metal/ferromagnet bilayers. This is achieved by analyzing the quadratic Kerr effect as well as the polar Kerr effect. The two effects can be distinguished by properly selecting the polarization of the incident light. We use this all-optical technique to determine the spin-orbit torques generated by a series of Pt/Permalloy samples, finding values in excellent agreement with spin-torque ferromagnetic resonance measurements.

description: Burn-in is accepted as a way to evaluate ageing effects in an accelerated manner. It has been suggested that burn-in stress may have a significant effect on the Negative Bias Temperature Instability (NBTI) of subthreshold CMOS circuits. This paper analyses the effect of burn-in on NBTI in the context of a Digital to Analogue Converter (DAC) circuit. Analogue circuits require matched device pairs; NBTI may cause mismatches and hence circuit failure. The NBTI degradation observed in the simulation analysis indicates that under severe stress conditions, a significant voltage threshold mismatch in the DAC beyond the design specification of 2 mV limit can result. Experimental results confirm the sensitivity of the DAC circuit design to NBTI resulting from burn-in.

description: In this paper we study isentropic flow in a curved pipe. We focus on the consequences of the geometry of the pipe on the dynamics of the flow. More precisely, we present the solution of the general Cauchy problem for isentropic fluid flow in an arbitrarily curved, piecewise smooth pipe. We consider initial data in the subsonic regime, with small total variation about a stationary solution. The proof relies on the front-tracking method and is based on [1].
Educating minority boys: examining the differences in children's classroom experiences as a result of teacher-child relationships and a professional development intervention
Creators: name: Mason, Erin Brown

description: This study examined differences in classroom experiences for minority boys as a result of their teacher-child relationships and a professional development intervention. The Student Teacher Relationship Scale was used to categorize boys in 23 prekindergarten through 3rd grade classrooms to relationships high in conflict or high in closeness. A time-sampling observation measure was used to observe the two boys with the highest conflictual and two boys with the highest in closeness relationships pre and post a professional development intervention. Independent samples t-tests and analysis of covariance tests were conducted to examine the differences in classroom experiences. Results indicate minority boys with conflictual relationships are less attentive than those with high in closeness relationships. Minority boys in the intervention group received more oral language development and scaffolding post intervention than those in the control group. The results have implications for school staff interested in bettering early school experiences for minority boys.

description: The detection and characterization of exoplanets have made huge progresses since the first discoveries in the late nineties. In particular, the independent measurement of the mass and radius of planets, by combining the transit and radial-velociy techniques, allowed exploring their density and hence, their internal structure. With CoRoT (2007-2012), the pioneering CNES space-based mission in this investigation, about thirty new planets were characterized. CoRoT has enhanced the diversity of giant exoplanets and discovered the first telluric exoplanet. Following CoRoT, the NASA Kepler mission has extended our knowledge to small-size planets, multiple systems and planets orbiting binaries. Exploring these new worlds will continue with the NASA/TESS (2017) and ESA/PLATO (2024) missions.

Primarily in this transition zone the bacteria strongly influenced the vertical oxygen diffusion and reduced the hydraulic conductivity due to biological clogging.
Explaining changes in the spread of Congressional Committee jurisdictions

description: Following the end of World War II, the United States government began to increase its involvement in domestic and non-military issues, responding to the needs of a country changing in terms of population growth and economic focus, which it primarily did through an increase in the number of agencies and bodies dealing with issue areas. The Congressional committee system, on the other hand, followed a different path, as Congress has responded to increases in the federal government's involvement in issue areas by allowing committees to become involved in more issues that are outside of its primary jurisdiction areas, with increase in diversity occurring over time. Using an analysis of entropy scores, which measure jurisdictional diversity, I show that increases in the size of government result in Congressional committees increasing their own jurisdictional diversity, increasing the number of issues individual committees are involved in.

description: In this paper, we study the Selmer groups of two congruent Galois representations over an admissible $p$-adic Lie extension. We will show that under appropriate congruence condition, if the dual Selmer group of one satisfies the $\M_H(G)$-property, so will the other. In the event that the $\M_H(G)$-property holds, and assuming certain further hypothesis on the decomposition of primes in the $p$-adic Lie extension, we compare the ranks of the $π$-free quotient of the two dual Selmer groups. We then apply our results to compare the characteristic elements attached to the Selmer groups. We also study the variation of the ranks of the $π$-free quotient of the dual Selmer groups of specialization of a big Galois representation. We emphasis that our results \textit{do not} assume the vanishing of the $μ$-invariant.

description: Corporations are now exploring the value of blogs as a marketing tool. This thesis investigates how corporate bloggers in the technology industry are using this new technique to communicate with customers. One blogger from each of the following companies: Cisco, IBM, HP, Microsoft, Sun, Adobe, Accenture, Red Hat, Oracle, and BEA, was interviewed through a series of on-line interviews. Using a basis of two-way communication theory, the interviews explored whether there is an effective blogging model technology companies can use and if blogs are a viable marketing tool for technology companies. Results demonstrate that blogs are a viable tool in the marketing mix, but this study was inconclusive in providing a model for other technology companies to adopt.

Mass Transit: Where Security and Sustainability Meet

Publisher: name: University of North Carolina at Chapel Hill

description: As it becomes apparent that increasing sustainability is a requirement to be a leading city in modern, globalized society, public and private actors are improving mass transit networks in cities around the world. At the same time, the threat of international terrorism is a security concern which must be addressed by modern cities, particularly those in Western countries like the United States and members of the European Union. This thesis looks at how mass transit, where sustainability and security converge, is dealing with these two realities of the twenty-first century, both of which have become significant issues only in recent decades. Brief histories of transit and terrorism are given prior to a more thorough analysis of security measures that have been taken by cities already, as well as some measures that could be taken in the future.

description: The effects of viscosity and small-scale atomic-level mixing on plasmas in inertial confinement fusion (ICF) currently represent challenges in ICF research. Many current ICF hydrodynamic codes ignore the effects of viscosity though recent research indicates viscosity and mixing by classical transport processes may have a substantial impact on implosion dynamics. We have implemented a Lagrange hydrodynamic code in one-dimensional spherical geometry with plasma viscosity and mass transport and including a three temperature model for ions, electrons, and radiation treated in a gray radiation diffusion approximation. The code is used to study ICF implosion differences with and without plasma viscosity and to determine the impacts of viscosity on temperature histories and neutron yield. It was found that plasma viscosity has substantial impacts on ICF shock dynamics characterized by shock burn timing, maximum burn temperatures, convergence ratio, and time history of neutron production rates. Plasma viscosity reduces the need for artificial viscosity to maintain numerical stability in the Lagrange formulation and also modifies the flux-limiting needed for electron thermal conduction.
Controlled interference of association paths in the conversion of ultracold atoms into molecules

description: We present a proposal for controlling the conversion of ultracold atoms into molecules by fixing the phase difference between two oscillating magnetic fields. The scheme is based on the use of a magnetic Feshbach resonance with a field modulation that incorporates terms oscillating with frequencies corresponding to the main resonance and one of the subharmonics. The interference between the two association processes activated by the oscillating terms is controlled via the phase difference. As a result, significant increase or decrease of the effective interaction strength can be achieved. The realization of the proposal is feasible under standard technical conditions. In particular, the method is found to be robust against the effect of the sources of decoherence present in the practical setup. The applicability of the approach to deal with quadratic terms in the field modulation is discussed.

description: Our goal is to determine the structural differences between different categories of networks and to use these differences to predict the network category. Existing work on this topic has looked at social networks such as Facebook, Twitter, co-author networks etc. We, instead, focus on a novel data set that we have assembled from a variety of sources, including law-enforcement agencies, financial institutions, commercial database providers and other similar organizations. The data set comprises networks of "persons of interest" with each network belonging to different categories such as suspected terrorists, convicted individuals etc. We demonstrate that such "anti-social" networks are qualitatively different from the usual social networks and that new techniques are required to identify and learn features of such networks for the purposes of prediction and classification. We propose Cliqster, a new generative Bernoulli process-based model for unweighted networks. The generating probabilities are the result of a decomposition which reflects a network's community structure. Using a maximum likelihood solution for the network inference leads to a least-squares problem. By solving this problem, we are able to present an efficient algorithm for transforming the network to a new space which is both concise and discriminative. This new space preserves the identity of the network as much as possible. Our algorithm is interpretable and intuitive. Finally, by comparing our research against the baseline method (SVD) and against a state-of-the-art Graphlet algorithm, we show the strength of our algorithm in discriminating between different categories of networks.

Theôria et praxis

description: Bien qu’ils soient généralement opposés sur la question de l’herméneutique et de l’historicisme, Hans-Georg Gadamer (1900-2002) et Leo Strauss (1899-1973) sont deux des plus grands représentants du retour contemporain à la pensée grecque, et plus particulièrement à Platon. Cette thèse cherche à éclairer le débat entre Gadamer et Strauss en insistant sur cet élément central de leurs philosophies respectives. En dépit de multiples accords interprétatifs sur les Dialogues, nous soutenons qu’un désaccord est également perceptible à même leurs lectures de Platon, à savoir qu’ils ne s’entendent pas sur la relation de la dimension théorétique et la dimension pratique de l’existence humaine dans la philosophie platonicienne. Nous cherchons d’abord à introduire les problématiques platoniciennes en analysant les réceptions gadamérienne et straussienne de l’interprétation d’Aristote proposée par Martin Heidegger dans les années 1920, laquelle influença de manière déterminante leur approche de Platon. Nous comparons ensuite leurs compréhensions de l’articulation entre theôria et praxis dans la philosophie platonicienne à l’égard de trois questions : 1) la signification pratique de la forme dialoguée ou dialogique de la philosophie ; 2) le rapport entre philosophie et poésie ; 3) le rapport entre politique et philosophie, a fortiori la philosophie comme recherche des Idées. En éclairant ainsi des points de convergence et de divergence entre Gadamer et Strauss en amont de la question de l’herméneutique et de l’historicisme, nous proposons un portrait plus complet et nuancé d’un dialogue qu’on tend trop souvent à réduire à une stricte opposition.
What Should I Do Now? Impact on Self-Efficacy of Seeing Conflicting Medical Information Online

description: Increasing numbers of contradictory reports fill online media with conflicting advice or recommendations for health information-seekers. Recent examples include the controversies over when and how often women should receive mammograms to screen for breast cancer and whether prostate-specific antigen (PSA) tests are effective in screening for prostate cancer or might, in fact, cause unnecessary surgeries and chemotherapy. This thesis uses an experimental model to measure responses to such conflicting reports in order to determine whether such exposure decreases individual feelings of self-efficacy in regard to competency to prevent cancer morbidity and mortality.

description: When the Air Force accidentally shipped six nuclear weapons across the country, it led to a breakdown in the confidence of the American public in the service. As the Air Force took action to repair its procedures, a series of dated regulations and communication errors kept the service from repairing its reputation. The conflict between the need to inform and the need to protect national security led to an inconsistent communication strategy that hamstrung the service and left its credibility crippled in an extended and multifaceted crisis. This case study examines the Air Force's mistakes and provides suggestions for how the military can better communicate with its stakeholders.

In this system, a 20 nt sequence on a single guide RNA (sgRNA) is the only gene-specific information required to modify a target gene. Fusarium head blight (FHB) is a devastating disease in wheat caused by the fungus Fusarium graminearum. The trichothecene it produces, deoxynivalenol (DON), is a major mycotoxin contaminant causing food production loss both in quality and yield. In this project, we used the CRISPR/Cas9 system to modify three wheat genes identified in previous experiments, including an ABC transporter (TaABCC6), and the Nuclear Transcription Factor X box-binding-Like 1 (TaNFXL1), both associated with FHB susceptibility, and a non-specific Lipid Transfer Protein (nsLTP) named TansLTP9.4 which correlates with FHB resistance. Two sgRNAs were designed to target each gene and were shown in an in vitro CRISPR/Cas9 assay to guide the sequence-specific cleavage with high efficiency. Another assay for CRISPR/Cas9 was established by the optimization of a wheat protoplast isolation and transformation system. Using a construct expressing a green fluorescent protein (GFP) as a positive control, estimated transformation efficiencies of about 60% were obtained with different batches of protoplasts. High-throughput sequencing of PCR amplicons from protoplasts transformed with editing constructs clearly showed that the three genes have been successfully edited with efficiencies of up to 42.2%. In addition, we also characterized by RT-qPCR the expression pattern of 10 genes in DON-treated protoplasts; seven of the genes were induced by DON in the protoplasts, consistent with their previously identified DON induction in treated wheat heads, while three genes expressed differentially between DON-treated wheat heads and protoplasts. Preliminary bioinformatics analyses showed that these differentially expressed genes are involved in different plant defense mechanisms.
Fortunes for the Bold: An Ecological Perspective on the Emergence of Private Military and Security Companies

description: The past two decades witnessed the emergence of a new population of organizations, private military and security companies. While there is a large volume of literature on the subject, most has focused on its relationship with state agents, governance structures, role definition, public accountability, the relative effectiveness of state and private actors and how they can best work together. While there are studies of individual organizations there has been little analysis of the entire population organizations. This study helps fill that gap in existing literature. It provides insight into organizational population emergence and industry dynamics using a data set of 1,477 private military and security companies. It contributes to organizational science by extending ecological analysis to an important new industry. It considers the role of independent entrepreneurial action in population emergence. Finally, it adds new and detailed information on this population not previously available.

description: The Hochschild-Kostant-Rosenberg theorem, which relates the Hochschild homology of an algebra to its modules of differential $n$-forms, can be considered a benchmark for smoothness of an algebra. This notion is used here in the search for a conception of smoothness formulated in the context of codifferential categories, both commutative and noncommutative. Since it is desirable to adapt such a conception to the noncommutative context, the theory of this domain is developed considerably; a significant result in this direction establishes a connection between noncommutative codifferential categories and commutative ones. This investigation necessitates, then, both the formulation of a notion of smoothness for $T$-algebras in codifferential categories and an adaptation of the Hochschild-Kostant-Rosenberg theorem to a wide variety of contexts which includes noncommutative ones. The former consideration fosters both the notion of a smooth monad, and a formulation of Andr\'e-Quillen homology in codifferential categories; the latter engenders a highly adaptable version of the Hochschild-Kostant-Rosenberg theorem. Specifically, it is shown that for any algebra modality there exists a corresponding Hochschild-Kostant-Rosenberg theorem. This includes a version of the theorem for the free associative algebra monad, the conclusion of which is satisfied by noncommutative smooth algebras.

description: The present study focuses on the chemical composition of the infusions of Sideritis raeseri subsp. raeseri from cultivated and wild populations using NMR, LC-DAD, LC-HRESIMS, and GC-MS techniques, to reveal possible differences. Mainly carbohydrates, flavonoids, and phenylethanoid glycosides were detected in the 1H-NMR spectra of both infusions. In the GC-MS analysis, carbohydrates were shown to be the main constituents in both infusions. Caffeic acid was found in traces only in the cultivated sample, while quinic and chlorogenic acids were detected in both samples. Further investigation by LC-HRESIMS unveiled the same constituents with only slight differences in the amounts. Although the Sideritis samples originated from wild and cultivated populations, similar metabolic profiles were observed in the infusions.

description: Turbulence can transport angular momentum in protoplanetary disks and influence the growth and evolution of planets. With spatially and spectrally resolved molecular emission line measurements provided by (sub)millimeter interferometric observations, it is possible to directly measure non-thermal motions in the disk gas that can be attributed to this turbulence. We report a new constraint on the turbulence in the disk around HD 163296, a nearby young A star, determined from ALMA Science Verification observations of four CO emission lines (the CO(3-2), CO(2-1), 13CO(2-1), and C18O(2-1) transitions). The different optical depths for these lines permit probes of non-thermal line-widths at a range of physical conditions (temperature and density) and depths into the disk interior. We derive stringent limits on the non-thermal motions in the upper layers of the outer disk such that any contribution to the line-widths from turbulence is <3% of the local sound speed. These limits are approximately an order of magnitude lower than theoretical predictions for full-blown MHD turbulence driven by the magneto-rotational instability, potentially suggesting that this mechanism is less efficient in the outer (R>30AU) disk than has been previously considered.

description: The Tumor Necrosis Factor Receptor Superfamily (TNFR) is responsible in regulating a myriad of physiological function including the regulation of the immune system. Among the members include CD137 (4-1BB), an inducible costimulatory receptor known for its potent activation, proliferation, and survival effects on T cells. Stimulation of NK cells with agonistic α-CD137 antibodies are known to increase IFN-γ production and proliferation in NK cells as well as increase efficacy of anti-tumor responses. However, NK cell death has also been seen in certain circumstances, although the mechanism remains to be determined. In vitro stimulation of NK cells revealed that α-CD137 induced NK cell death occurs through both TNFR1 and TNFR2, although the action of TNF-α and TNF-ß remain uncertain. Death was independent of other cytotoxic mechanisms such as granzyme/perforin, Fas-Fas ligand, and TRAIL. During MCMV infection, α-CD137 induces NK cell death during the early phase of infection reducing viral resistance. This causes increased viral proliferation which drives NK cell proliferation, likely through Ly49H-m157 interactions, to high levels by day 4 of infection. The use of α-CD137 as a tumor therapeutic is promising with several applications undergoing clinical trials. However, my results raise concern of other effects including the depletion of NK cells. This may cause a temporary impairment in immune function against pathogenic infections and a compensatory reaction of NK cell proliferation, both of which may cause damage to the host. However, with proper co-stimulation or co-treatments, this impairment may be overcome and prevent adverse effects in patients.

description: Cette thèse vise à mieux comprendre l’articulation entre la trajectoire de participation sociale des immigrants et l’épreuve d’intégration dont ces derniers doivent s’acquitter dans la société d’installation. À partir d’une approche par parcours de vie, elle se concentre plus particulièrement sur les immigrants originaires de la République démocratique du Congo installés d’une part dans la Région de Bruxelles-Capitale (Belgique) et d’autre part dans la région d’Ottawa-Gatineau. J’utilise ici la notion de participation sociale pour examiner différentes pratiques d’engagement social comme des pratiques de don de temps pour le bien commun. La notion d’« épreuve d’intégration » se base, quant à elle, sur les travaux de Serge Paugam (2014) sur les liens sociaux et l’intégration ainsi que sur la notion d’épreuve mise de l’avant par Danilo Martuccelli. Les données présentées ici proviennent principalement de récits de vie recueillis sur ces deux terrains de recherche. Ces récits ont été complétés par des entrevues d’informateurs-clés et d’experts ainsi que par plusieurs séances d’observation participante au sein de structures de participation dans lesquelles des immigrants congolais étaient engagés. La conclusion majeure de cette thèse est que la trajectoire de participation sociale permet d’apporter des réponses partielles à l’épreuve d’intégration. Ces réponses structurent la façon dont les individus créent des liens sociaux au travers de leur trajectoire de participation. Elles dépendent en partie de la visibilité des pratiques de participation des répondants.
