description: Background: Primary orthostatic tremor (POT) is an infrequent disorder whose physiopathology is unknown. Current medication is largely ineffective or only offers mild benefits.

Case Report: A 75-year-old female with refractory POT treated with 4 mg/day of perampanel achieved complete symptom resolution. Owing to adverse effects, the patient reduced intake to 2 mg/day, but even at this lower dose the benefit was maintained.

Discussion: We report the complete resolution of POT symptoms using low doses of perampanel, an antiepileptic drug that blocks glutamate-mediated post-synaptic excitation. Further controlled studies are necessary to confirm this finding.

description: We derive general bounds on operator dimensions, central charges, and OPE coefficients in 4D conformal and N=1 superconformal field theories. In any CFT containing a scalar primary phi of dimension d we show that crossing symmetry of implies a completely general lower bound on the central charge c >= f_c(d). Similarly, in CFTs containing a complex scalar charged under global symmetries, we bound a combination of symmetry current two-point function coefficients tau^{IJ} and flavor charges. We extend these bounds to N=1 superconformal theories by deriving the superconformal block expansions for four-point functions of a chiral superfield Phi and its conjugate. In this case we derive bounds on the OPE coefficients of scalar operators appearing in the Phi x Phi* OPE, and show that there is an upper bound on the dimension of Phi* Phi when dim(Phi) is close to 1. We also present even more stringent bounds on c and tau^{IJ}. In supersymmetric gauge theories believed to flow to superconformal fixed points one can use anomaly matching to explicitly check whether these bounds are satisfied.

description: The world is evolving towards an Internet of Things (IoT) where a large number of devices interact to realize different applications that constitute smart electricity grids, intelligent transportation systems, ubiquitous healthcare solutions, etc. Machine Type Communications (MTC) provide the substrate for the connectivity and service mechanisms of these devices. Many services associated with the MTC applications such as smart metering and location tracking require the cellular network as the backbone for communication and are instrumental in driving the growth of the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) / LTE-Advanced (LTE-A) standards. A substantial number of MTC User Equipment (UE) hosting IoT applications are expected to be low cost, low data rate devices requiring prolonged battery life. In the downlink, the current LTE/LTE-A standards adopt Discontinuous Reception (DRX) mechanism for power reduction, which requires the UE to wake up periodically to check for a paging message from the base station. The LTE/LTEA standardization activities have identified that intricate paging decode procedures increase the energy consumption for low complexity MTC UEs, necessitating enhancements to the current mechanisms. This encourages us to investigate novel energy efficient mechanisms for LTE MTC systems. Specifically, we develop DRX with Quick Sleeping Indication (QSI), which enables the MTC UEs to go back to sleep quickly and save power, when there is no impending page from the base station. We also design the enhanced Primary Synchronization Signal (ePSS) for faster timing resynchronization, which can be used as QSI for additional improvements in the downlink energy efficiency of MTC UEs in low coverage. Further, LTE/LTE-A standardization activities in the uplink are examining different procedures to reduce UE data retransmissions for improved energy efficiency. To this end, we develop a Maximum Likelihood (ML) based uplink Carrier Frequency Offset (CFO) estimation technique for the LTE/LTE-A base station, which is robust and accurate in low coverage, enhancing the uplink energy efficiency of MTC UEs. The MTC mechanisms described in this thesis are not only simple to implement, but also require minimal changes to the present LTE/LTE-A standardization framework, promoting smooth integration into the current LTE/LTE-A networks.

description: We perform a comprehensive study of the impact of new-physics operators with different Lorentz structures on CP-violating observables involving the b -> s mu+ mu- transition. We examine the effects of new vector-axial vector (VA), scalar-pseudoscalar (SP) and tensor (T) interactions on the CP asymmetries in the branching ratios and forward-backward asymmetries of Bs -> mu mu, B -> Xs mu mu, Bs -> mu mu gamma, B -> K mu mu, and B -> K* mu mu. In B -> K* mu mu, we also explore the direct CP asymmetries in the longitudinal polarization fraction f_L and the angular asymmetries A_T^{(2)} and A_{LT}, as well as the triple-product CP asymmetries A_T^{(im)} and A^{(im)}_{LT}. We find that, in almost all cases, the CP-violating observables are sensitive only to new physics which involves VA operators. The VA new physics may therefore be unambiguously identified by a combined analysis of future measurements of these CP-violating observables.

description: Examinations of the words we use in our daily lives have shown that certain linguistic patterns may be indicators of underlying depressogenic schemata. The Linguistic Inquiry and Word Count (LIWC) and multidimensional scaling (MDS) have been used as methods of computerized text analysis to yield insight into how people’s language use may be reflective of maladaptive psychological processes, including self-focused attention, rumination, and absolutist thinking, which are all associated with the depressogenic schemata. These findings demonstrate the significance of analyzing people’s language use in the mental health profession. Research in this interdisciplinary field of natural language processing, applied linguistics, and mental health not only corroborates psychological theories regarding depression but further yields implications for prevention, diagnosis, and outcome predictions of mental health depression and anxiety.

description: Education Leadership Data Analytics (ELDA) is an emerging domain that is centered at the intersection of education leadership, the use of evidence-based improvement cycles in schools to promote instructional improvement, and education data science. ELDA practitioners work collaboratively with school and district leaders and teachers to analyze, pattern, and visualize previously unknown patterns and information from the vast sets of data collected by schooling organizations, and then integrate findings in easy to understand language and digital tools into collaborative and community-building evidence-based improvement cycles with stakeholders. In June of 2018, over 100 participants gathered for the Education Leadership Data Analytics Summit at Teachers College, Columbia University in New York City, including researchers, practitioners, policymakers, and funders. This report provides a summary of the central issues, themes, and recommendations for the future of the field that emerged from the discussions at the ELDA Summit event. These issues include building capacity in the field through incentivizing researcher practitioner partnerships, and providing conference and networking opportunities, professional development, certification, and ultimately degree programs to train ELDA researchers and practitioners. Additionally, a central focus of the ELDA field is equity, data security and privacy, in concert with open and FAIR data standards to develop and share de-identified data and tools across contexts. We conclude the report with a blueprint of possible skills and competencies needed for ELDA practitioner training and professional development and provide recommendations for next steps to help grow the field.
An approximate Bayesian marginal likelihood approach for estimating finite mixtures

Subjects: subject: Methodology (stat.ME)

description: Estimation of finite mixture models when the mixing distribution support is unknown is an important problem. This paper gives a new approach based on a marginal likelihood for the unknown support. Motivated by a Bayesian Dirichlet prior model, a computationally efficient stochastic approximation version of the marginal likelihood is proposed and large-sample theory is presented. By restricting the support to a finite grid, a simulated annealing method is employed to maximize the marginal likelihood and estimate the support. Real and simulated data examples show that this novel stochastic approximation--simulated annealing procedure compares favorably to existing methods.

description: We study the effect of a finite quark mass on the quark number susceptibility in the framework of holographic QCD. We work in a bottom-up model with a deformed AdS black hole and D3/D7 model to calculate the quark number susceptibility at finite temperature with/without a finite quark chemical potential. As expected the finite quark mass suppresses the quark number susceptibility. We find that at high temperatures $T\ge 600$ MeV the quark number susceptibility of light quarks and heavy quarks are almost equal in the bottom-up model. This indicates that the heavy quark like charm contribution to thermodynamics of a QCD-like system may start to become significant at temperatures $T\sim 600$ MeV. In D3/D7 model, we focus on the competition between the quark chemical potential, which enhances the quark number susceptibility, and the quark mass that suppresses the susceptibility. We observe that depending on the relative values of the quark mass and the quark chemical potential, the quark number susceptibility shows a diverging or converging behavior. We also calculate the chiral susceptibility in D3/D7 model to support the observation made with the quark number susceptibility.

description: The aim of this thesis was to examine the contribution of nurses to interprofessional collaboration (IPC) in the operating room (OR) guided by the Interprofessional Education Collaborative Patient Care Practice (IECPCP) framework. First, a secondary analysis of interviews with 19 registered nurses was conducted. Twenty emergent themes were identified. The most prevalent of the four dimensions (internalization; shared goals and vision; governance; and formalization) consisted of the internalization dimension relating to human interaction and sense of belonging within the interprofessional team. A scoping review then identified 20 studies evaluating four interventions (briefings, checklists, team training, and debriefings) used to improve IPC in the OR. Despite weak study designs, these interventions showed improvements in communication, teamwork, and safety outcomes. OR nurses contribute mainly through interactional processes and they require organizational support to foster their efforts in IPC. Nurse are involved in all IPC interventions and their contribution is important to support IPC in the OR.
Modeling the behavior of labor migration in Thailand : does the wage play an important role in labor migration
Creators: name: Phasuk, Suvaporn
Publisher: name: University of British Columbia
Year: 2017

description: This dissertation uses individual-level data from Thailand’s Labor Force Survey to explain labor migration, with special attention to the effect of wage rates. By using the nested logit model, and dividing the provinces into four regions, the model fits well with regard to the flexibility of independent irrelevant alternatives for migrants who move to a province to look for a job. The results show that wage rates have the largest effect of all factors on labor migration decisions. A 1% increase in wages in a province leads to an average increase of 3% in the probability of single male migrants in agricultural and non-agricultural sectors moving to such a province to find a new job. Nonetheless, in a struggling economy, food and housing expenses become dominant factors. For single male migrants in the agricultural sector moving to a province, the effect of rice prices on that decision is statistically insignificant. The effect of the non-agriculture sector wage on labor migration was significant, positive, and relatively large. If there is a 1% increase in non-agriculture sector wages of a province, it raises the probability of single male migrants migrating to that province by 4.63%, an impressively elastic response. This research also found that agricultural workers had zero benefit in terms of their wage rate from raising rice prices, and thus raising prices of agricultural products did not induce workers to move to the agricultural sector.

description: In a recent letter, it has been predicted within first principle studies that Mn-doped ZrO2 compounds could be good candidate for spintronics application because expected to exhibit ferromagnetism far beyond room temperature. Our purpose is to address this issue experimentally for Mn-doped tetragonal zirconia. We have prepared polycrystalline samples of Y0.15(Zr0.85-yMny)O2 (y=0, 0.05, 0.10, 0.15 & 0.20) by using standard solid state method at equilibrium. The obtained samples were carefully characterized by using x-ray diffraction, scanning electron microscopy, elemental color mapping, X-ray photoemission spectroscopy and magnetization measurements. From the detailed structural analyses, we have observed that the 5% Mn doped compound crystallized into two symmetries (dominating tetragonal & monoclinic), whereas higher Mn doped compounds are found to be in the tetragonal symmetry only. The spectral splitting of the Mn 3s core-level x-ray photoelectron spectra confirms that Mn ions are in the Mn3+ oxidation state and indicate a local magnetic moment of about 4.5 μB/Mn. Magnetic measurements showed that compounds up to 10% of Mn doping are paramagnetic with antiferromagnetic interactions. However, higher Mn doped compound exhibits local ferrimagnetic ordering. Thus, no ferromagnetism has been observed for all Mn-doped tetragonal ZrO2 samples.

description: The observation of quark and gluon jets has played a crucial role in establishing Quantum Chromodynamics [QCD] as the theory of the strong interactions within the Standard Model of particle physics. The jets, narrowly collimated bundles of hadrons, reflect configurations of quarks and gluons at short distances. Thus, by analysing energy and angular distributions of the jets experimentally, the properties of the basic constituents of matter and the strong forces acting between them can be explored. In this review, which is primarily a description of the discovery of the quark and gluon jets and the impact of their observation on Quantum Chromodynamics, we elaborate, in particular, the role of the gluons as the carriers of the strong force. Focusing on these basic points, jets in $e^+ e^-$ collisions will be in the foreground of the discussion and we will concentrate on the theory that was contemporary with the relevant experiments at the electron-positron colliders. In addition we will delineate the role of jets as tools for exploring other particle aspects in $ep$ and $pp/p\bar{p}$ collisions - quark and gluon densities in protons, measurements of the QCD coupling, fundamental 2-2 quark/gluon scattering processes, but also the impact of jet decays of top quarks, and $W^\pm, Z$ bosons on the electroweak sector. The presentation to a large extent is formulated in a non-technical language with the intent to recall the significant steps historically and convey the significance of this field also to communities beyond high energy physics.

In this value-added product, we compile continuum and emission line measurements around the Halpha, Hbeta, MgII and CIV regions, as well as other quantities such as radio properties, broad absorption line quasar (BALQSO) flags, and disk emitters. We also compile virial black hole mass estimates based on various calibrations. For the fiducial virial mass estimates we use the Vestergaard & Peterson (VP06) calibrations for Hbeta and CIV, and our own calibration for MgII which matches the VP06 Hbeta masses on average. We describe the construction of this catalog, and discuss its limitations. The catalog and its future updates will be made publicly available online.

description: Breast cancer is a highly heterogeneous disease with multiple drivers and a complex regulatory network. Periostin (Postn) is a matricellular protein involved in a plethora of cancer types and other diseases. More specifically, Postn has been shown to be involved in various processes of tumor progression such as angiogenesis, cell survival, invasion, and metastasis. A high Postn level in breast cancer has been corelated with a more aggressive phenotype. Despite extensive research, it remains unclear what Postn is doing to the cancer environment and how cancer cells regulate Postn. Here, we assessed the role and regulation mechanisms of Postn in ErbB2-mediated tumorigenesis. By crossing Postn deficient animals into the oncogenic NeuNDL model of ErbB2-positive breast cancer, we have shown that Postn deletion delays tumor onset and increases overall survival by affecting proliferation and apoptosis. These tumors also showed a decrease in collagen deposition which is the proposed mechanism for its effect in vivo. Using isolated cancer cells from the Postn deficient background we assessed re-expression of Postn which had no effect on in vitro tumorigenesis processes or in vivo subcutaneous growth in immunodeficient mice. Furthermore, we established an in vitro model to study the regulation of Postn using a bovine pituitary gland derived extract as a natural repressor of Postn. Using mass spectrometry and RNA sequencing, we identified potential regulators of Postn gene expression. We also showed a cross regulation between FGFR, TGFβ and PI3K/AKT pathways to regulate Postn expression. In ErbB2-mediated murine breast cancer cells, we found that TGFβ can induce Postn expression in a SMAD-independent manner while bFGF can repress Postn expression through a PKC-dependent pathway. Postn induction and repression by TGFβ and bFGF respectively, are both dependent on PI3K/AKT signaling. Overall, these results suggest a cancer-driving function for Postn and reveal a novel mechanism for regulating Postn expression.

description: The internal dynamics of a double quantum dot system is renormalized due to coupling respectively with transport electrodes and a dissipative heat bath. Their essential differences are identified unambiguously in the context of full counting statistics. The electrode coupling caused level detuning renormalization gives rise to a fast-to-slow transport mechanism, which is not resolved at all in the average current, but revealed uniquely by pronounced super-Poissonian shot noise and skewness. The heat bath coupling introduces an interdot coupling renormalization, which results in asymmetric Fano factor and an intriguing change of line shape in the skewness.

Literary Self-Translation and Self-Translators in Canada (1971-2016): A Large-Scale Study

description: This thesis constitutes a first large-scale study of literary self-translators and self-translations in Canada, with self-translation understood as interlinguistic and intertextual transfer where the same legal person is responsible for writing the antecedent and subsequent texts. Three main questions guide this investigation: To what extent is Canada fertile ground for self-translation? What does it mean to self-translate in Canada? Why does self-translation in Canada matter? After situating Canada-based research within broader self-translation scholarship, I engage in a critical analysis of the definition and implications of self-translation and contextualize the theoretical, sociopolitical and methodological rationale for studying Canada and adopting a macroscopic approach to examining self-translations and their writers in this country. The thesis predominantly revolves around self-translation artefacts produced by three groups of writers who self-translated in Canada at least once between 1971 and 2016: 1) those self-translating exclusively between English and French; and those self-translating into and/or out of 2) Spanish; or 3) standard Italian. Exploring the theme of collaboration, I propose a new typology of collaborative self-translation, attempting to account for both process- and product-related considerations. In examining the theme of frequency, I identify self-translators and discuss their relative distribution vis-à-vis language, generation, country of birth and location within Canada; I also map out a conceptual framework for defining and counting self-translation products, proposing new ways of understanding and classifying writers in light of their self-translational productivity. In considering the theme of language, I analyze how writers and their self-translations can be characterized in relation to language variety, language combinations and language directionality. In this thesis, I argue that Canada is a significant hub of heterogeneous self-translational activity, and that large-scale, quantitative and product-oriented study constitutes a useful research approach that can generate rich findings and complement other forms of investigation. The thesis also contains an extensive appendix in which I identify Canadian self-translators and their self-translations.

Television interviews

description: Media discourse has been attracting numerous conversation analysts’ attention within the past one or two decades (e.g., Clayman & Heritage, 2002; Hutchby, 2006). TV talk shows, as a “semi-institutional” context which contains coexisting features of both daily conversation and institutional language (Ilie, 2001), has particularly aroused many scholars’ interest. In talk shows, hosts exploit various interactional practices to elicit their guests’ responses. This paper uses a conversation analytic framework to examine one specific interviewer practice—the designedly incomplete utterance (DIU) (Koshik, 2002)—in the context of TV talk shows. Three uses of DIUs by talk show hosts are identified: (1) to facilitate a (more extended) response (2) to initiate collaborative turn completion, and (3) to avoid repeating questions that have already been asked in prior turns.

HIV-positive women

description: Background:
Women account for 23% of newly diagnosed HIV infections in the United States, but there are few recent, well-characterized cohorts of U.S. women in whom behavior characteristics and HIV acquisition have been well-described.

Objective:
To evaluate HIV incidence and describe behaviors among U.S. women residing in areas of high HIV prevalence.

Design:
Multisite, longitudinal cohort of women who had HIV rapid testing and audio computer-assisted self-interviews at baseline and every 6 months for up to 12 months. (ClinicalTrials.gov: NCT00995176)

Setting:
10 urban and periurban communities with high HIV prevalence and poverty rates, located in the northeastern and southeastern United States.

Patients:
Venue-based sampling was used to recruit women aged 18 to 44 years who recently had unprotected sex and had 1 or more additional personal or partner risk factors and no self-reported previous HIV diagnosis.

Measurements:
HIV prevalence and incidence, frequency of HIV risk behaviors, and health status perceptions.

Results:
Among 2099 high-risk women (85.9% black and 11.7% of Hispanic ethnicity), 32 (1.5%) were diagnosed with HIV infection at enrollment. Annual HIV incidence was 0.32% (95% CI, 0.14% to 0.74%). Older age, substance use, and knowing a partner had HIV were associated with HIV prevalence. Ten women died during the study (0.61% per year).

Limitations:
Longitudinal assessment of risk behaviors was limited to a maximum of 12 months. There were few incident HIV infections, precluding identification of characteristics predictive of HIV acquisition.

Conclusion:
This study enrolled a cohort of women with HIV incidence substantially higher than the Centers for Disease Control and Prevention national estimate in the general population of U.S. black women. Concerted efforts to improve preventive health care strategies for HIV and overall health status are needed for similar populations.

description: A brief study on avifaunal diversity was carried out at Pt. Ravishankar Shukla University Campus, Raipur (Chhattisgarh) during the month of August to mid September, 2015. For this study, we used “watching and visual survey” method. Field binocular (8X40 magnifications) was used for visual surveys and photographs were taken by a digital camera. Our results revealed thirty two (32) bird species in this short period with 29 genera and placed taxonomically under 21 families which were further arranged systematically under 10 orders. Passeriformes was found to be the dominating group with 19 bird species.

description: The chief psychoactive constituent of many bioactive phytocannabinoids (D9-tetrahydrocannabinol, D9-THC) found in hemp, cannabis or marijuana plants are scientifically denoted by the Latin term, Cannabis sativa, acts on cell surface receptors. These receptors are ubiquitously expressed. To date, two cannabinoid receptors have been cloned and characterized. Cannabinoid receptor type 1 (CB1R) is found to serve as the archetype for cannabinoid action in the brain. They have attracted wide interest as the mediator of all psychoactive properties of exogenous and endogenous cannabinoids and they are abundantly expressed on most inhibitory and excitatory neurons. Recent evidence established that cannabinoid receptor type 2 (CB2R) is also expressed in the neurons at both presynaptic and postsynaptic terminals and are involved in neuropsychiatric effects. Distinct types of cells in many regions in the brain express CB2Rs and the cellular origin of CB2Rs that induce specific behavioral effects are emerging. To mimic the bliss effects of marijuana, synthetic cannabinoids (SCBs) have been sprayed onto plant material, and this plant material has been consequently packaged and sold under brand name “Spice” or “K2”. These SCBs have been shown to maintain their affinity and functional activity for CB1R and CB2R and have been shown to cause severe harmful effects when compared to the effects of D9-THC. The present review discusses the potential brain mechanisms that are involved in the deleterious effects of SCBs.

description: In this paper we complete the determination of the index of factoriality of moduli spaces of semistable sheaves on an abelian or projective K3 surface $S$. If $v=2w$ is a Mukai vector, $w$ is primitive, $w^{2}=2$ and $H$ is a generic polarization, let $M_{v}(S,H)$ be the moduli space of $H-$semistable sheaves on $S$ with Mukai vector $v$. First, we describe in terms of $v$ the pure weight-two Hodge structure and the Beauville form on the second integral cohomology of the symplectic resolutions of $M_{v}(S,H)$ (when $S$ is K3) and of the fiber $K_{v}(S,H)$ of the Albanese map of $M_{v}(S,H)$ (when $S$ is abelian). Then, if $S$ is K3 we show that $M_{v}(S,H)$ is either locally factorial or $2-$factorial, and we give an example of both cases. If $S$ is abelian, we show that $M_{v}(S,H)$ and $K_{v}(S,H)$ are $2-$factorial.

description: We report the enhancement of the optical second harmonic signal in non-centrosymmetric semiconductor CdS quantum dots, when they are placed in close contact with isolated silver nanoparticles. The intensity enhancement is about 1000. We also show that the enhancement increases when the incoming laser frequency $ω$ is tuned toward the spectral position of the silver plasmon at $2ω$, proving that the silver nanoparticle modifies the nonlinear emission.

description: Neurofilament (NFL) proteins have recently been found to play unique roles in synapses. NFL is known to interact with the GluN1 subunit of N-methyl-D-aspartic acid (NMDAR) and be reduced in schizophrenia though functional consequences are unknown. Here we investigated whether the interaction of NFL with GluN1 modulates synaptic transmission and schizophrenia-associated behaviors. The interaction of NFL with GluN1 was assessed by means of molecular, pharmacological, electrophysiological, magnetic resonance spectroscopy (MRS), and schizophreniaassociated behavior analyses. NFL deficits cause an NMDAR hypofunction phenotype including abnormal hippocampal function, as seen in schizophrenia. NFL−/− deletion in mice reduces dendritic spines and GluN1 protein levels, elevates ubiquitin-dependent turnover of GluN1 and hippocampal glutamate measured by MRS, and depresses hippocampal long-term potentiation. NMDAR-related behaviors are also impaired, including pup retrieval, spatial and social memory, prepulse inhibition, night-time activity, and response to NMDAR antagonist, whereas motor deficits are minimal. Importantly, partially lowering NFL in NFL+/− mice to levels seen regionally in schizophrenia, induced similar but milder NMDAR-related synaptic and behavioral deficits. Our findings support an emerging view that central nervous system neurofilament subunits including NFL in the present report, serve distinctive, critical roles in synapses relevant to neuropsychiatric diseases.
Consumer welfare and private actions for damages in European Union competition law
Creators: name: Zegrean, Ivona-Elena

description: In the European Union (“EU”) public enforcement of competition law prevails. Private enforcement is scarce and has not been encouraged or advocated for until the end of 2014, when the EU Parliament passed Directive 2014/104/EU, which sets out an EU-wide framework aimed at promoting and facilitating private damages actions for parties harmed by anticompetitive behaviour. This thesis inquires whether Directive 2014/104/EU succeeds in creating sufficient and appropriate incentives for victims of competition law infringements. The main argument is that while the preparatory work leading to the adoption of the Directive focused on lowering the barriers of access to justice for victims of anticompetitive conduct and incentivizing victims to take legal action against infringing firms, the final version of the Directive partly misses these points. The limited access to evidence provided by the Directive undermines the goal of lowering the burden and standard of proof, because it will still be difficult for claimants to obtain the necessary evidence for building their case, especially in standalone actions. The complete lack of any provisions facilitating class actions for the recovery of damages fails to lower litigation costs and has the effect of keeping in a particularly disadvantaged position consumers and small firms, for which litigation costs are usually prohibitive. These problems are exacerbated by the limitations of public enforcement: public enforcement agencies, due to their limited resources, have to prioritize the violations that warrant enforcement action and let some infringements go unpunished. In this context, despite the consumer welfare objective of EU competition law aiming to prevent the situation where wealth is illegally redistributed from consumers to competition law infringers, the restricted ability of victims to recover damages has the effect of allowing competition law infringers to keep most of their illegal gains.

description: We obtain expressions for the asymptotic distributions of the Rényi and Tsallis of order q entropies and Fisher information when computed on the maximum likelihood estimator of probabilities from multinomial random samples. We verify that these asymptotic models, two of which (Tsallis and Fisher) are normal, describe well a variety of simulated data. In addition, we obtain test statistics for comparing (possibly different types of) entropies from two samples without requiring the same number of categories. Finally, we apply these tests to social survey data and verify that the results are consistent but more general than those obtained with a χ2 test.
Smoluchowski dynamics and the ergodic-nonergodic transition

description: We use the recently introduced theory for the kinetics of systems of classical particles to investigate systems driven by Smoluchowski dynamics. We investigate the existence of ergodic-nonergodic (ENE) transitions near the liquid-glass transition. We develop a self-consistent perturbation theory in terms of an effective two-body potential. We work to second order in this potential. At second order we have an explicit relationship between the static structure factor and the effective potential. We choose the static structure factor in the case of hard spheres to be given by the solution of the Percus-Yevick approximation for hard spheres. Then using the analytically determined ENE equation for the ergodicity function we find an ENE transition for packing fraction, eta, greater than a critical value eta*=0.76 which is physically unaccessible. The existence of a linear fluctuation-dissipation theorem in the problem is shown and used to great advantage.

Shear thickening and migration in granular suspensions

description: We study the emergence of shear thickening in dense suspensions of non-Brownian particles. We combine local velocity and concentration measurements using Magnetic Resonance Imaging with macroscopic rheometry experiments. In steady state, we observe that the material is heterogeneous, and we find that that the local rheology presents a continuous transition at low shear rate from a viscous to a shear thickening, Bagnoldian, behavior with shear stresses proportional to the shear rate squared, as predicted by a scaling analysis. We show that the heterogeneity results from an unexpectedly fast migration of grains, which we attribute to the emergence of the Bagnoldian rheology. The migration process is observed to be accompanied by macroscopic transient discontinuous shear thickening, which is consequently not an intrinsic property of granular suspensions.
