Indigenous elders' pedagogy for land-based health education programs : Gee-zhee-kan'dug Cedar pedagogical pathways
Creators: name: Young, Alannah Earl
Publisher: name: University of British Columbia
Year: 2015

description: This qualitative research articulates and develops an Anishnabe-Nehiyaw Cree perspective of a tribal pedagogy. The author weaves elements of critical ethnographies, Indigenous oral histories and critical tribal and feminist theories throughout the dissertation. She describes five pedagogical pathways that were developed through an Indigenous conversation method (Kovach, 2010) in 8 research circles with 18 Indigenous Elders in central, rural Manitoba. The research utilizes Indigenous storywork methodologies to gather and interpret the research on Indigenous local land-based pedagogies. The specific Gee-zhee-kan’-dug Cedar pedagogy is described by the Indigenous Elders who teach at a 24 year long land-based health education program. The author outlines five pedagogical learning pathways as key findings, which are: 1) culture: facilitating access to the revitalization of tribal Indigenous knowledges; 2) land: developing local co-partnerships and genealogies connected to territories; 3) orality: using story, ceremony, songs, prayers, language, dreams, performance, and genealogy as the primary modes of teaching; 4) community: aligning educators with local self-determining initiatives such as food sovereignty and access to healthy water and plant medicines; and 5) ethics: interweaving practices with sustainable, health-enhancing and decolonizing agendas. From the example of this Cedar pedagogy, the researcher proposes a framework for educators who want to develop their own local, land-based pedagogies. This framework includes five elements: 1) research local Indigenous nation’s culture and stories, and partner with appropriate resource people; 2) prepare materials and information required for students to learn in the class and on the land, and make space for and provide access to Indigenous knowledge holders; 3) follow local protocol principles, including proper expression of the value principles, negotiate local relationships to land, and modify protocol principles for each context; 4) apply the pedagogy by taking people out on the land, encouraging the use of all of the senses, and engaging respectfully with local peoples and places; and 5) reflect on the experience by sharing local stories of transformation and reconnection to lands/plants. The research concludes with a discussion on how Indigenous knowledge systems can inform land-based pedagogies, and how these pedagogies can have a pivotal role in strengthening peoples’ wholistic health.

description: Reaction of Fe3(CO)12 and Ph2PH in the presence of Et3N in THF at 0 °C immediately forms Fe2(CO)6(μ-PPh2)(μ-OH) (1), Fe2(CO)6(μ-PPh2)(μ-k2O,P-OPPh2) (2), and Fe2(CO)6(μ-PPh2)2 (3) in yields of 25, 14, and 19%, respectively. Experiments confirm that Et3N shortens the reaction time. The absence of O2 hinders the formation of 2. The presence of H2O can increase the yield of 1. Their structures have been determined by X-ray crystallography and the complexes have been completely characterized by EA, IR, and 1H, 13C, 31P NMR. Electrochemical studies reveal that they exhibit catalytic H2-producing activities.

description: We introduce a new statistical test of the hypothesis that a balanced panel of firms have the same growth rate distribution or, more generally, that they share the same functional form of growth rate distribution. We applied the test to European Union and US publicly quoted manufacturing firms data, considering functional forms belonging to the Subbotin family of distributions. While our hypotheses are rejected for the vast majority of sets at the sector level, we cannot rejected them at the subsector level, indicating that homogenous panels of firms could be described by a common functional form of growth rate distribution.

description: For the SwissFEL Free Electron Laser project at the Paul Scherrer Institute, a pulsed High Gradient (HG) electron gun was used to study low emittance electron sources. Different metals and surface treatments for the cathode and anode were studied for their HG suitability. Diamond Like Carbon (DLC) coatings are found to perform exceptionally well for vacuum gap insulation. A set of DLC coated electrodes with different coating parameters were tested for both vacuum breakdown and photo electron emission. Surface electric fields over 250MV/m (350 - 400kV, pulsed) were achieved without breakdown. From the same surface, it was possible to photo-emit an electron beam at gradients up to 150MV/m. The test setup and the experimental results are presented

description: The greatest comorbidity of sleep disorders is observed with anxiety-depressive disorders. A bi-directional relationship was revealed between them, which indicates their ability to aggravate each other's course and influence the treatment process. Dyssomnia can persist even after elimination of the primary disease and increase the risk of recurrence in the future. Therefore, the treatment of anxiety-depressive disorders requires special attention to the correction of sleep disorders. The aim of the study was to evaluate the effectiveness of the developed complex, phased differentiated rehabilitation program, based on the analysis of the dynamics of psychopathological phenomena and the indicator of the quality of life of patients suffering from anxiety-depressive disorders of organic genesis with sleep disorders. The study was carried out using the clinical and psychopathological method supplemented by the hospital scale HADS, the Ch.Morin insomnia severity index, the psychometric scale of asthenic state, the J. Mezzich integrative life quality indicator, descriptive and analytical statistics methods. To achieve this goal, 60 patients with anxiety-depressive disorders of organic genesis and sleep disorders were studied, which were divided into 2 groups depending on the therapy used. The results show that patients who were treated according to the developed comprehensive program, the compensation of anxiety-depressive symptoms and sleep stabilization were more intensive and the results of the indicators were better compared with the control group. Furthermore, the indicator of the life quality of the main group was higher in comparison with the control group. Hence, the results of the study demonstrate the effectiveness of the comprehensive rehabilitation program developed by us in the treatment of patients with anxiety-depressive disorders of organic genesis with sleep disorders.

description: In order to advance next-generation communication systems, it is critical to enhance the state-of-the-art communication architectures, such as device-to-device (D2D), multiple- input multiple-output (MIMO), and intelligent reflecting surface (IRS), in terms of achieving high data rate, low latency, and high energy efficiency. In the first part of this dissertation, we address joint learning and optimization methodologies on cutting-edge network archi- tectures. First, we consider D2D networks equipped with MIMO systems. In particular, we address the problem of minimizing the network overhead in D2D networks, defined as the sum of time and energy required for processing tasks at devices, through the design for MIMO beamforming and communication/computation resource allocation. Second, we address IRS-assisted communication systems. Specifically, we study an adaptive IRS control scheme considering realistic IRS reflection behavior and channel environments, and propose a novel adaptive codebook-based limited feedback protocol and learning-based solutions for codebook updates.
 Furthermore, in order for revolutionary innovations to emerge for future generations of communications, it is crucial to explore and address fundamental, long-standing open problems for communications, such as the design of practical codes for a variety of important channel models. In the later part of this dissertation, we study the design of practical codes for feedback-enabled communication channels, i.e., feedback codes. The existing feedback codes, which have been developed over the past six decades, have been demonstrated to be vulnerable to high forward/feedback noises, due to the non-triviality of the design of feedback codes. We propose a novel recurrent neural network (RNN) autoencoder-based architecture to mitigate the susceptibility to high channel noises by incorporating domain knowledge into the design of the deep learning architecture. Using this architecture, we suggest a new class of non-linear feedback codes that increase robustness to forward/feedback noise in additive White Gaussian noise (AWGN) channels with feedback.

description: We introduce a new quantum adversary method to prove lower bounds on the query complexity of the quantum state generation problem. This problem encompasses both, the computation of partial or total functions and the preparation of target quantum states. There has been hope for quite some time that quantum state generation might be a route to tackle the {\sc Graph Isomorphism} problem. We show that for the related problem of {\sc Index Erasure} our method leads to a lower bound of $Ω(\sqrt N)$ which matches an upper bound obtained via reduction to quantum search on $N$ elements. This closes an open problem first raised by Shi [FOCS'02]. Our approach is based on two ideas: (i) on the one hand we generalize the known additive and multiplicative adversary methods to the case of quantum state generation, (ii) on the other hand we show how the symmetries of the underlying problem can be leveraged for the design of optimal adversary matrices and dramatically simplify the computation of adversary bounds. Taken together, these two ideas give the new result for {\sc Index Erasure} by using the representation theory of the symmetric group. Also, the method can lead to lower bounds even for small success probability, contrary to the standard adversary method. Furthermore, we answer an open question due to Špalek [CCC'08] by showing that the multiplicative version of the adversary method is stronger than the additive one for any problem. Finally, we prove that the multiplicative bound satisfies a strong direct product theorem, extending a result by Špalek to quantum state generation problems.

description: All the current global models of the heliosphere are based on the assumption that the magnetic field in the heliosheath, in the region close to the heliopause is laminar. We argue that in that region the heliospheric magnetic field is not laminar but instead consists of magnetic bubbles. Recently, we proposed that the annihilation of the "sectored" magnetic field within the heliosheath as it is compressed on its approach to the heliopause produces the anomalous cosmic rays and also energetic electrons. As a product of the annihilation of the sectored magnetic field, densely-packed magnetic islands/bubbles are produced. These magnetic islands/bubbles will be convected with the ambient flows as the sector region is carried to higher latitudes filling the heliosheath. We further argue that the magnetic islands/bubbles will develop upstream within the heliosheath. As a result, the magnetic field in the heliosheath sector region will be disordered well upstream of the heliopause. We present a 3D MHD simulation with very high numerical resolution that captures the north-south boundaries of the sector region. We show that due to the high pressure of the interstellar magnetic field a north-south asymmetry develops such that the disordered sectored region fills a large portion of the northern part of the heliosphere with a smaller extension in the southern hemisphere. We suggest that this scenario is supported by the following changes that occur around 2008 and from 2009.16 onward: a) the sudden decrease in the intensity of low energy electrons detected by Voyager 2; b) a sharp reduction in the intensity of fluctuations of the radial flow; and c) the dramatic differences in intensity trends between GCRs at V1 and 2. We argue that these observations are a consequence of V2 leaving the sector region of disordered field during these periods and crossing into a region of unipolar laminar field.

description: It is shown that given two copies of a q-ary input channel $W$, where q is prime, it is possible to create two channels $W^-$ and $W^+$ whose symmetric capacities satisfy $I(W^-)\le I(W)\le I(W^+)$, where the inequalities are strict except in trivial cases. This leads to a simple proof of channel polarization in the q-ary case.

Calculated the costs of processing transit wagons at the sorting station, attributable to each element of the time spent by the wagons. The cost of processing one dispatched transit wagon has been determined. Such a wide-format daily analysis of the operation of the sorting station model allows the formation of statistical patterns of non-fulfillment of the norms for the time spent by wagons at the station and to carry out daily control and manage the implementation of the main quality indicator of the station operation.

description: Recent radial-velocity surveys for GK clump giants have revealed that planets also exist around ~1.5-3 Msun stars. However, no planets have been found inside 0.6 AU around clump giants, in contrast to solar-type main-sequence stars, many of which harbor short-period planets such as hot Jupiters. In this study we examine the possibility that planets were engulfed by host stars evolving on the red-giant branch (RGB). We integrate the orbital evolution of planets in the RGB and helium burning (HeB) phases of host stars, including the effects of stellar tide and stellar mass loss. Then we derive the critical semimajor axis (or the survival limit) inside which planets are eventually engulfed by their host stars after tidal decay of their orbits. Especially, we investigate the impact of stellar mass and other stellar parameters on the survival limit in more detail than previous studies. In addition, we make detailed comparison with measured semimajor axes of planets detected so far, which no previous study did. We find that the critical semimajor axis is quite sensitive to stellar mass in the range between 1.7 and 2.1 Msun, which suggests a need for careful comparison between theoretical and observational limits of existence of planets. Our comparison demonstrates that all those planets are beyond the survival limit, which is consistent with the planet-engulfment hypothesis. However, on the high-mass side (> 2.1 Msun), the detected planets are orbiting significantly far from the survival limit, which suggests that engulfment by host stars may not be the main reason for the observed lack of short-period giant planets. To confirm our conclusion, the detection of more planets around clump giants, especially with masses > 2.5 Msun, is required.

title: Neighbourhood Effects on Jihadist Radicalisation in Germany? Some Case-Based Remarks
Creators: name: Hüttermann, Jörg

Subjects: neighborhood effects, radicalization, neo-Salafism, jihadism, milieu, emergence

description: About twenty young people travelled from a small German former mining settlement named Dinslaken-Lohberg to become fighters with al-Nusra and ISIS. They drew particular attention, with media reports about “members” of what they termed the “Lohberg Brigade” killed in the fighting, or in air strikes by the anti-ISIS coalition, or in spectacular suicide attacks claiming many victims. Drawing on that case, the article explores how neighborhood can effect the emergence and persistence of radicalisation to jihadi neo-Salafism. The author presents a series of local elements that interfere with one another to strengthen each other’s persistence and effects and thus promote the emergence and persistence of the radicalisation phenomenon at hand. The interference of elements is not an automatic but a social process, enacted by neighbors telling stories of conspiracy, of discrimination and recounting experiences of spirituality, heroism, masculinity, and femaleness. It is performed by neighbors setting, crossing and avoiding symbolic boundaries. And finally it is played by neighbors simply following their routines. The author shows how explaining space-related radicalisation processes means more than adding up spatial factors. His approach rejects the idea of isolating a single social fact – such as local structures, events, processes or social actors that existed, occurred or acted prior to the emergence of radicals in their neighbourhood – as definite cause for radicalisation.

description: We discuss the properties of an object in the Subaru Deep Field (SDF) classified as a galaxy in on-line data bases and revealed on the Subaru images as a genuine polar-ring galaxy (PRG) candidate. We analyse available photometric data and conclude that this object consists of a >5 Gyr old early-type central body surrounded by a faint, narrow inner ring tilted at a ~25 deg angle relative to the polar axis of the host galaxy. The halo surrounding the main stellar body exhibits a diversity of spatially extended stellar features of low surface brightness, including a faint asymmetric stellar cloud and two prominent loops. These faint features, together with the unperturbed morphology of the central host, are clear signs of a recent coalescence of two highly unequal mass galaxies, most likely a pre-existing early-type galaxy and a close-by gas-rich dwarf galaxy. The presumed stellar remnants observed near the edges of the ring, including possibly the surviving captured companion itself, indicate that the merger is still taking place.

description: We examine the thermally-induced fracture of an unstrained polymer chain of discrete segments coupled by an anharmonic potential by means of Molecular Dynamics simulation with a Langevin thermostat. Cases of both under- and over-damped dynamics are investigated, and a comparison with recent studies of bond scission in model polymers with harmonic interactions is performed. We find that the polymer degradation changes qualitatively between the inertial regime and that of heavily damped dynamics. The role of bond healing (recombination) is also studied and probability distributions for the recombination times and overstretched bond lengths are obtained. Our extensive simulations reveal many properties of the scission dynamics in agreement with the notion of random breakdown of independent bonds, e.g., the mean time of chain rupture, $$ follows an Arrhenian behavior with temperature $T$, and depends on the number of bonds $N$ in the polymer as $ \propto N^{-1}$. In contrast, the rupture rates of the individual bonds along the polymer backbone indicate clearly the presence of self-induced inhomogeneity resulting from the interplay of thermal noise and nonlinearity. Eventually we examine the fragmentation kinetics during thermolysis. We demonstrate that both the probability distribution function of fragment sizes as well as the mean length of fragments at subsequent times $t$ characterize degradation as predominantly a first order reaction.

description: The article is prepared on a topical issue related to improving the efficiency of the logistics system functioning of the combined arms force. Thus far, the logistics support of the combined arms force is at the initial stage of formation and represents an unbalanced system that operates in certain areas and types of support in the absence of a unified effective management system. The implementation of the suggested recommendations will allow to develop an approach to the formation of an effective structure of the logistics system of the combined arms force, to increase the efficiency of the system functioning. Reducing the average time (term) to replenish or restore the relevant stocks to a level commensurate with the average period of sustainable operation of the system due to the suggested technique and recommendations will allow to reduce the likelihood of detection of these objects and thus increase the survivability of the system as a whole in the logistics units.

Identification and characterization of dosage mutator genes in Saccharomyces cerevisiae
Creators: name: Ang, J. Sidney
Publisher: name: University of British Columbia
Year: 2015

description: Cancer is due to an accumulation of mutations in constellations of genes that cause uncontrolled proliferation and evasion of apoptotic pathways. In addition, mutations that cause genome instability, another hallmark of cancer, predispose cancer progenitor cells to accumulating the large number of mutations and chromosome aberrations that are observed in cancer cells. Genome instability is either due to mutations that cause an increased mutation rate (mutator phenotype) or increases in aberrations to chromosome number or structure (chromosome instability). Recent work has cataloged nearly all genes in the budding yeast, Saccharomyces cerevisiae, that cause a chromosome instability (CIN) phenotype due to reduction-of-function mutations and gain-of-function mutations, with the ultimate goal of translating the results found in yeast to human cancer. To investigate the effects of gene dosage on mutation rate, we systematically overexpressed ~85% of the yeast genome in a CAN1 forward-mutation screen and identified 5 genes that when overexpressed conferred a strong mutator phenotype, several of which have been associated with cancer. Overexpression of MPH1, the yeast ortholog of Fanconi Anemia gene FANCM, resulted in the strongest mutator phenotype. MPH1 was further investigated to gain insight into the mechanisms which lead to its dosage mutator phenotype.

description: A heterostructuring strategy is an effective approach for abiding problems referred to as the strength-ductility trade-off. However, tailoring the heterostructure is an arduous problem. This work synthesized hierarchically heterogeneity by combining the eutectic high-entropy alloy (EHEA) and medium-entropy alloy powders through novel powder metallurgy-based severe plastic deformation (P-SPD). EHEA forms nano-scaled heterogeneity composed of FCC and B2, and the mixture of powder types forms micro-scale heterogeneity with hard and soft domains. This hierarchically heterogeneous microstructure leads to strong hetero-deformation-induced strengthening, achieving a yield strength of ∼1.5 GPa. The present P-SPD represents the feasibility of heterostructuring, aiding the development of HEAs. A hierarchically heterogeneous microstructure comprised of the eutectic high-entropy alloy and medium-entropy alloy was synthesized by the P-SPD procedures and achieved supreme mechanical properties attributed by hetero-deformation-induced strengthening.

description: We examine a class of N=2 supersymmetric gauge theories in (3+1) dimensions whose Lagrangians are determined by graphs consisting of two building blocks, namely a tri-vertex and a line. A line represents an SU(2) gauge group and a tri-vertex represents a matter field in the trifundamental representation of SU(2)^3. These graphs can be topologically classified by the genus and the number of external legs. This paper focuses on the hypermultiplet moduli spaces of the aforementioned theories. We compute the Hilbert series which count all chiral operators on the hypermultiplet moduli space. Several examples show that theories corresponding to different graphs with the same genus and the same number of external legs possess the same Hilbert series. This is in agreement with the conjecture that such theories are related to each other by S-duality. We also give a general expression for the Hilbert series for the graph with any genus and any number of external legs.

ECERIFERUM7 subunit of the exosome, SUPERKILLER complex and small RNA species regulate cuticular wax biosynthesis in Arabidopsis thaliana stems
Creators: name: Zhao, Lifang
Publisher: name: University of British Columbia
Year: 2016

description: The primary aerial surfaces of higher plants are covered by a continuous hydrophobic lipid layer called the cuticle, which is synthesized by the epidermal cells and provides protection against desiccation and environmental stresses. The cuticle is mainly composed of the cutin polyester matrix and cuticular waxes. Although the biosynthetic pathways of cuticular waxes are relatively well documented, how wax biosynthesis is regulated is not completely understood. The major goal of my thesis was to investigate the ECERIFERUM7 (CER7)-mediated mechanism of regulation of cuticular wax biosynthesis in stems of Arabidopsis thaliana. In particular, I was interested in investigating that how the Arabidopsis CER7 protein, a core component of the exosome complex that determines cellular RNA levels, was involved in this process. CER7 was proposed to degrade an mRNA encoding a repressor of wax biosynthetic gene CER3 to activate CER3 transcription required for stem wax biosynthesis. To identify the CER3 repressor and additional components of CER7 regulatory pathway, I carried out a cer7 suppressor screen and isolated mutants capable of restoring wild-type stem wax loads in the absence of CER7 activity. Characterization of these suppressor mutants and cloning of the affected genes resulted in a series of discoveries. First, cloning of RNA DEPENDENT RNA POLYMERASE 1 and SUPPRESSOR OF GENE SILENCING 3 from the suppressors demonstrated that small interfering RNAs (siRNAs) participate in CER7-mediated regulation of wax formation (Chapter 2). Second, forward genetics and reverse genetics, combined with small RNA sequencing confirmed that trans-acting siRNAs (tasiRNAs) are direct regulators of CER3 gene in CER7-controlled wax biosynthetic pathway (Chapter 3). Third, CER7 and tasiRNA-mediated regulation of CER3 during stem wax deposition requires the SUPERKILLER complex, which is known to be involved in cytoplasmic activities of the exosome in yeast and metazoan (Chapter 4).

description: We have studied the tensile deformation behaviour of thin films of aging aqueous suspension of Laponite, a model soft glassy material, when subjected to a creep flow field generated by a constant engineering normal stress. Aqueous suspension of Laponite demonstrates aging behaviour wherein it undergoes time dependent enhancement of its elastic modulus as well as its characteristic relaxation time. However, under application of the normal stress, the rate of aging decreases and in the limit of high stress, the aging stops with the suspension now undergoing a plastic deformation. Overall, it is observed that the aging that occurs over short creep times at small normal stresses is same as the aging that occurs over long creep times at large normal stresses. This observation allows us to suggest an aging time - process time - normal stress superposition principle, which can predict rheological behaviour at longer times by carrying out short time tests.

description: Utilizing a series of N-body simulations, we argue that gravitationally bound stellar clusters of modest population evolve very differently from the picture presented by classical dynamical relaxation theory. The system's most massive stars rapidly sink towards the center and form binary systems. These binaries efficiently heat the cluster, reversing any incipient core contraction and driving a subsequent phase of global expansion. Most previous theoretical studies demonstrating deep and persistent dynamical relaxation have either conflated the process with mass segregation, ignored three-body interactions, or else adopted the artificial assumption that all cluster members are single stars of identical mass. In such a uniform-mass cluster, binary formation is greatly delayed, as we confirm here both numerically and analytically. The relative duration of core contraction and global expansion is effected by stellar evolution, which causes the most massive stars to die out before they form binaries. In clusters of higher N, the epoch of dynamical relaxation lasts for progressively longer periods. By extrapolating our results to much larger populations, we can understand, at least qualitatively, why some globular clusters reach the point of true core collapse.

description: Perceived influxes in biased reporting, disparities in reporting versus reality, and other factors have led many Americans to question the legitimacy of their most-frequented sources. These sentiments have encouraged migration from traditional sources to alternative ones, exposing many Americans to polarizing media. This report argues that unaddressed inadequacies in reporting force Americans to contend with a distorted reality or try their luck on the path toward alternative media.
Survey of political bots on Twitter

Publisher: name: No Publisher Supplied

description: Bots are software applications that execute automated tasks called scripts over the Internet. Bots have become predominant on social media platforms like Twitter, and automate their interactions with other users. Political Twitter bots have emerged that focus their activity on elections, policy issues, and political crises. These political bots have faced increased scrutiny as a result of their association with online manipulation via the spread of misinformation. As bots have become more sophisticated, research has focused on advanced methods to detect their presence on social media platforms. However, little research has been performed on the overall presence of political bots and their dynamic response to political events. The research that has been performed on political bots focuses on these bots in the context of scheduled political events, such as elections. In this paper, we explore the bot response to an unexpected political event, describe the overall presence of political bots on Twitter, and design and employ a model to identify them based on their user profile alone. We collected data for more than 700,000 accounts tweeting with hashtags related to political events in the United States between May 2018 and October 2018. We designed a machine learning algorithm using user profile features alone that achieves approximately 97.4% accuracy in identifying political Twitter bots. In our analysis, we found (1) new bot accounts are created in response to political events, (2) bot accounts are more active during political controversies, (3) the number of tweets an account has favorited (liked) is a strong determinant of bot status.

description: Excess contributions to the free energy due to interfaces occur for many problems encountered in the statistical physics of condensed matter when coexistence between different phases is possible (e.g. wetting phenomena, nucleation, crystal growth, etc.). This article reviews two methods to estimate both interfacial free energies and line tensions by Monte Carlo simulations of simple models, (e.g. the Ising model, a symmetrical binary Lennard-Jones fluid exhibiting a miscibility gap, and a simple Lennard-Jones fluid). One method is based on thermodynamic integration. This method is useful to study flat and inclined interfaces for Ising lattices, allowing also the estimation of line tensions of three-phase contact lines, when the interfaces meet walls (where "surface fields" may act). A generalization to off-lattice systems is described as well. The second method is based on the sampling of the order parameter distribution of the system throughout the two-phase coexistence region of the model. Both the interface free energies of flat interfaces and of (spherical or cylindrical) droplets (or bubbles) can be estimated, including also systems with walls, where sphere-cap shaped wall-attached droplets occur. The curvature-dependence of the interfacial free energy is discussed, and estimates for the line tensions are compared to results from the thermodynamic integration method. Basic limitations of all these methods are critically discussed, and an outlook on other approaches is given.

Renormalization of minimally doubled fermions

description: We investigate the renormalization properties of minimally doubled fermions, at one loop in perturbation theory. Our study is based on the two particular realizations of Borici-Creutz and Karsten-Wilczek. A common feature of both formulations is the breaking of hyper-cubic symmetry, which requires that the lattice actions are supplemented by suitable counterterms. We show that three counterterms are required in each case and determine their coefficients to one loop in perturbation theory. For both actions we compute the vacuum polarization of the gluon. It is shown that no power divergences appear and that all contributions which arise from the breaking of Lorentz symmetry are cancelled by the counterterms. We also derive the conserved vector and axial-vector currents for Karsten-Wilczek fermions. Like in the case of the previously studied Borici-Creutz action, one obtains simple expressions, involving only nearest-neighbour sites. We suggest methods how to fix the coefficients of the counterterms non-perturbatively and discuss the implications of our findings for practical simulations.

On the constants in a Kato inequality for the Euler and Navier-Stokes equations

description: We continue an analysis, started in [10], of some issues related to the incompressible Euler or Navier-Stokes (NS) equations on a d-dimensional torus T^d. More specifically, we consider the quadratic term in these equations; this arises from the bilinear map (v, w) -> v . D w, where v, w : T^d -> R^d are two velocity fields. We derive upper and lower bounds for the constants in some inequalities related to the above bilinear map; these bounds hold, in particular, for the sharp constants G_{n d} = G_n in the Kato inequality | < v . D w | w >_n | <= G_n || v ||_n || w ||^2_n, where n in (d/2 + 1, + infinity) and v, w are in the Sobolev spaces H^n, H^(n+1) of zero mean, divergence free vector fields of orders n and n+1, respectively. As examples, the numerical values of our upper and lower bounds are reported for d=3 and some values of n. When combined with the results of [10] on another inequality, the results of the present paper can be employed to set up fully quantitative error estimates for the approximate solutions of the Euler/NS equations, or to derive quantitative bounds on the time of existence of the exact solutions with specified initial data; a sketch of this program is given.

description: The article considers ways to increase the professional competence of dental students in the study of internal medicine by using interactive teaching methods while preparing for practical classes. The paper analyzes the effectiveness of using one of the methods of simulation training in the learning process, on the example of a business game. The introduction of the methodology of this game will contribute to the implementation of such principles of modern higher education as: optimal combination of group and individual forms of organization of the educational process in higher education; rational application of modern methods and teaching aids at different stages of training. Therefore, in the process of conducting classes, in particular in internal medicine, the use of this type of training in combination with other interactive and traditional technologies is an integral part of the process of training future doctors.
