Subjects: ING-INF/01 Elettronica

description: The modelling and test of a single stage and a two-stage monolithic millimetre-wave (Ka-Band) pseudomorphic HEMT feedback amplifier is reported. The amplifiers used 0.25µm x 120µm devices and were processed on 200µm thick GaAs wafers. The PHEMT s-parameters were measured on-wafer to 40GHz in conjunction with on-wafer Line-Reflect-Line (LRL) calibration standards, which are described. The amplifier modelling approach combined a device equivalent circuit model with a fullwave analysis of the microstrip features and selected measurement-based foundry models. Measured and fitted data are compared for the PHEMT device and for the amplifiers. A single stage feedback amplifier gain of 7.8dB was measured at 33.8GHz and a two-stage feedback amplifier gain of 13.2dB ± 0.4dB from 28.6GHz to 37.9GHz. Both measurements were in good agreement with simulations. The on-wafer measured noise figure of the two stage amplifier was 3.4dB at 35GHz.

description: This paper describes a systematic method to design wideband 90° phase shifter circuits to be implemented using MMIC technology. The circuit structuresare based on the combination of two RC-all pass filters, and the proposed method allows the computation of circuit elements in a simple manner for minimum phase shift and amplitud errors over any frequency range. One of the RC-all pass filter structure is an active structure which has no losses. A 90" phase shifter circuit has been designed using this method, the phase shift errror and amplitud error are 2° and 1 dB over more than two octave bandwidth, ( 0.8 - 4.8 Ghz ).
Restorative justice and mental illness : combating the "spider syndrome"
Creators: name: Dwornik, Ania
Publisher: name: University of British Columbia
Year: 2014

description: This study explores the experiences and perspectives of three restorative justice (RJ) practitioners who processed cases involving service users with serious and persistent mental illness. Participants were recruited in the United Kingdom with the help of restorative justice contacts in London, England. The three practitioners who came forward took part in one semi-structured interview that lasted approximately one hour. A descriptive framework was used and emerging themes were coded. Research findings show that personal contact along with mental health education appeared to increase participants’ willingness to process RJ cases with service users who have serious and persistent mental illness, due to a subsequent reduction in stigmatizing thoughts and behaviours. The latter are components of what one of the participants referred to as the “Spider Syndrome”: fears and misconceptions that occur due to a lack of knowledge and understanding. This, along with participants’ own recommendations, suggests that mental health training which focuses specifically on skills and raising awareness, in combination with increased exposure to individuals who have serious mental illness, could be an important contributor to enhancing practitioner skill and increasing the use of RJ with such service users. Findings also suggest that restorative justice can be used as a stigma-reducing tool, both at the practitioner and service user level. These insights may hold important implications for social work, mental health and development of practice in the field of restorative justice.

description: LiFeAs is one of the iron-based superconductors having multiple gaps with the possible sign reversal. To clarify how those novel natures affect the energy dissipation of magnetic vortices, we investigated the microwave surface impedance of LiFeAs single crystals under finite magnetic fields. The flux-flow resistivity enhanced rapidly at low magnetic fields, which is similar to the case of MgB$_{2}$. This is probably the consequence of the multiple-gap nature and the gap anisotropy. This suggest that the sign-reversal is not important for the flux-flow even for multiple-gap superconductors. As for the electronic state, the vortex core of LiFeAs turned out to be "moderately clean". Furthermore, the mean free path inside the vortex core was much shorter than that outside, and was close to the core radius. These results strongly suggest a process specific to the core boundary is important for a scattering mechanism inside the vortex core.

description: This paper uses a logit model to estimate whether and to what extent Maryland’s Priority Funding Area (PFA) program steers urban growth to locations inside targeted growth area boundaries of an ex-urban county in the outer suburbs of the Washington, D.C. region. The results of our model indicate that the size of an agricultural parcel, its distance from urban parcels, its proximity to highways, the quality of the land for agriculture, and the location in or outside of PFAs influence the probability an agricultural parcel will remain in agriculture or be converted to urban use. We find that some of the areas experiencing the greatest market pressure for development are located outside PFAs and, although Maryland’s incentive-based strategy reduces the likelihood a parcel outside a PFA will transition to urban use, this policy is not one hundred percent effective.

description: Emission reduction strategies are gaining greater attention to support the national objective for a sustainable and green transportation system. A large percent of emission contribution that arises from transportation modes are primarily from auto and truck travel. Reductions in highway travel require prudent planning strategies and modeling user’s response to planner’s policies. Modeling planning goals and user’s response is a challenging task. In this paper the authors present a joint travel demand and environmental model to incorporate vehicle emission pricing (VEP) as a strategy for emission reduction. First, the travel demand model determines the destination, mode and route choice of the users in response to the VEP strategy set by the planner. Second, the emission model provides NOx, VOC, and CO2 estimates at a very detailed level. A Base-case and three models are proposed to incorporate VEP in a multimodal transportation network. The objective function of the Base-case is the minimization of Total System Travel Time (TST), and the models are designed with the objective of minimizing Total System Emission (TSE). User Equilibrium method is used for travel to model user responses and solved by Frank Wolfe algorithm. The Base-case represents “do-nothing” conditions and the three models address the interactions between planner’s perspectives and user responses to VEP strategies. The proposed model is applied to Montgomery County’s (located in the Washington DC-Baltimore region) multimodal transportation network. The case study results show that VEP can be used as a tool for emission reduction in transportation planning and policy.

description: We derive bounds on the mixing between the left-chiral ("active") and the right-chiral ("sterile") neutrinos, provided from the combination of neutrino oscillation data and direct experimental searches for sterile neutrinos. We demonstrate that the mixing of sterile neutrinos with any flavour can be significantly suppressed, provided that the angle theta_13 is non-zero. This means that the lower bounds on sterile neutrino lifetime, coming from the negative results of direct experimental searches can be relaxed (by as much as the order of magnitude at some masses). We also demonstrate that the results of the negative searches of sterile neutrinos with PS191 and CHARM experiments are not applicable directly to the see-saw models. The reinterpretation of these results provides up to the order of magnitude stronger bounds on sterile neutrino lifetime than previously discussed in the literature. We discuss the implications of our results for the Neutrino Minimal Standard Model (the NuMSM).

description: We prove that all Gibbs states of the q-state nearest neighbor Potts model on Z^2 below the critical temperature are convex combinations of the q pure phases; in particular, they are all translation invariant. To achieve this goal, we consider such models in large finite boxes with arbitrary boundary condition, and prove that the center of the box lies deeply inside a pure phase with high probability. Our estimate of the finite-volume error term is of essentially optimal order, which stems from the Brownian scaling of fluctuating interfaces. The results hold at any supercritical value of the inverse temperature.

description: Pflanzen leben in einer komplexen wechselhaften Umgebung. Zentraler Bestandteil der Abwehrantwort sind MAPK Signalkaskaden, die nach Pathogenerkennung durch Phosphorylierung von Substratproteinen eine Signalweiterleitung ermöglichen. Diese Phosphorylierung führt zur Modulation verschiedener Abwehrantworten. Nur eine geringe Zahl an MAPK-Substratproteinen ist beschrieben. Diese Arbeit identifiziert eine neue Klasse von MAPK-Substraten, Proline Rich Protein (PRP), PRP Homolog 1 (PH1) und PRP Homolog 2 (PH2). Diese Proteine sind in vitro Kinase-Substrate von MPK3/6. Gezielte Mutagenese-Experimente zeigten, dass PRP-ähnliche Proteine eine MAPK docking domain besitzen sowie eine konservierte Phosphorylierungsstelle vorliegt. Flg22 und elf18 können PRP und PH1 transkriptionell aktivieren. PRP-ähnliche Proteine können die Promoteraktivität der Abwehr-relevanten Gene FRK1 und NHL10 erhöhen. In PRP-Überexpressionslinien wurde eine erhöhte Resistenz gegen P. syringae nachgewiesen. Diese Arbeit identifizierte PRP-ähnliche Proteine als neue MAPK-Substratklasse, die eine Rolle in der Abwehrantwort Arabidopsis spielen.
description: Plants are surrounded by a complex, ever changing environment. The MAPK signaling cascade is central to conveying the perceived signals of pathogen presence to downstream substrates through phosphorylation events. These modifications lead to modulation of various defence related responses. A small number of these MAPK substrates have been identified to date. Three proteins, Proline Rich Protein (PRP), PRP Homolog 1 (PH1) and PRP Homolog 2 (PH2), are in vitro kinase substrates of MPK3 and MPK6. Targeted mutagenesis revealed that the PRP-like proteins posses a MAPK docking domain that is required for the interaction with MAPKs and revealed that MPK3 and MPK6 target a conserved phospho in all three proteins. Both PRP and PH1 are transcriptionally activated by the MAMPs flg22 and elf18. Co-expression of the PRP-like proteins augment the promoter activities of the defense related genes, FRK1 and NHL10. Finally, transgenic lines over-expressing PRP displayed an increased resistance to Pseudomonas syringae. This study identified the PRP-like proteins as a novel class of MAPK substrates that may have a role in defence related responses in Arabidopsis.

We study in particular the spiraling motion of a vortex in a cylinder that is parallel to the rotation axis. We determine the asymptotic form of the vortex and its axial and azimuthal propagation velocities under a wide range of parameters. We also study the stability of the vortex line and the effect of tilting the cylinder from the rotation axis.

description: The interest in Logarithmic Conformal Field Theories (LCFTs) has been growing over the last few years thanks to recent developments coming from various approaches. A particularly fruitful point of view consists in considering lattice models as regularizations for such quantum field theories. The indecomposability then encountered in the representation theory of the corresponding finite-dimensional associative algebras exactly mimics the Virasoro indecomposable modules expected to arise in the continuum limit. In this paper, we study in detail the so-called Temperley-Lieb (TL) fusion functor introduced in physics by Read and Saleur [Nucl. Phys. B 777, 316 (2007)]. Using quantum group results, we provide rigorous calculations of the fusion of various TL modules. Our results are illustrated by many explicit examples relevant for physics. We discuss how indecomposability arises in the "lattice" fusion and compare the mechanisms involved with similar observations in the corresponding field theory. We also discuss the physical meaning of our lattice fusion rules in terms of indecomposable operator-product expansions of quantum fields.

description: Es wurde der Einfluss von Hypoxie und reaktiver Sauerstoffspezies (ROS) auf die Proliferation von Melanozyten und Melanomzellen sowie die daran beteiligten Signalwege untersucht. Dazu wurden bei Melanomzelllinien und Melanozyten der Anteil an Zellen, welche über erhöhte ROS-Mengen verfügten, bestimmt. Mittels eines Westernblots wurden die Zellen auf die Expression der Transkriptionsfaktoren HIF-1α, HIF-2α und Nrf2 untersucht. Diese sind für die Anpassung an Hypoxie und ROS besonders relevant. Die Zellkulturen wurden für unterschiedlich lange Zeiträume unter hypoxischen Wachstumsbedingungen kultiviert. Im Anschluss wurde die daraus resultierende Änderung des Proliferationsverhaltens ausgewertet. Zudem wurden Signalwege, die für die Anpassung an Hypoxie und ROS bedeutend sind, durch Zugabe von Chemikalien gezielt beeinflusst. Dadurch sollte eine proliferationshemmende oder –stimulierende Wirkung erzielt werden. Anhand von Gewebepräparaten waren Rückschlüsse auf die in vivo Situation möglich. Dabei wurde auch eine mögliche Korrelation zwischen Hypoxie und der Expression von Melanomstammzellmarkern untersucht, um zu überprüfen, ob die Expression von Hypoxiemarkern als Prognosefaktor herangezogen werden kann. Die gewonnenen Daten sollen zu einem besseren Verständnis des Einflusses von Hypoxie und oxidativem Stress für die Entstehung und Proliferation des malignen Melanoms beitragen.

description: More and more people tend to gain information about the pandemic from social network
and they may change their opinions about coronavirus accordingly. Therefore, the effect
of social media should not be ignored in the spreading of COVID-19. This paper will
investigate whether sentiments expressed on social media would affect the spreading of
COVID-19. The correlation between sentiments on Twitter and the COVID-19 cases in a
particular range of time will be explored using statistical methods, such as Pearson’s
correlation, and Spearman's Rho with time-series analysis. The result shows that there is
no strong correlation between sentiments on Twitter and spreading of COVID-19.

Diese Pflege ist mit einer hohen physischen und psychischen Belastung für die pflegenden Angehörigen verbunden. Der Hausarzt gilt als eine wichtige Quelle für Informationen für pflegende Angehörige. Es wurden 10 Hausärzte zu ihren Erfahrungen mit pflegenden Angehörigen interviewt. Die Interviews wurden transkribiert und analog der Qualitativen Inhaltsanalyse nach Mayring analysiert. Zu den Aufgaben des Hausarztes bei der Betreuung pflegender Angehöriger gehören die Bereitstellung von Informationen, die Organisation des Pflegeablaufes und die Anleitung der Angehörigen zur Pflege. Kommt es zu kritischen Pflegesituationen fungiert der Hausarzt als Entscheidungshilfe. Durch die Komplexität einer Pflegesituation und zahlreiche Akteure aus Familie und Pflege nimmt der Hausarzt eine zentrale Vermittlerrolle ein. Um dieser Rolle gerecht zu werden, bedient sich der Hausarzt verschiedener Strategien. Um eine hochwertige Versorgung pflegender Angehöriger zu gewährleisten, benötigt der Hausarzt Zeit und kommunikatives Geschick. Damit die Bedürfnisse pflegender Angehöriger erfüllt werden können, müssen diese Bedürfnisse vom Hausarzt erkannt und angesprochen werden. Häufig verschwindet der pflegende Angehörige hinter dem zu Pflegenden und potenziell gesundheitsgefährdende Störungen des pflegenden Angehörigen werden übersehen oder erst spät erkannt. Hier gilt es die Hausärzte für die Belange von pflegenden Angehörigen zu sensibilisieren und aufzuklären.

description: Spatially homogeneous but totally anisotropic and non-flat Bianchi type II cosmological model has been studied in general relativity in the presence of two minimally interacting fluids; a perfect fluid as the matter fluid and a hypothetical anisotropic fluid as the dark energy fluid. The Einstein's field equations have been solved by applying two kinematical ansätze: we have assumed the variation law for the mean Hubble parameter that yields a constant value of deceleration parameter, and one of the components of the shear tensor has been considered proportional to the mean Hubble parameter. We have particularly dwelled on the accelerating models with non-divergent expansion anisotropy as the Universe evolves. Yielding anisotropic pressure, the fluid we consider in the context of dark energy, can produce results that can be produced in the presence of isotropic fluid in accordance with the ΛCDM cosmology. However, the derived model gives additional opportunities by being able to allow kinematics that cannot be produced in the presence of fluids that yield only isotropic pressure. We have obtained well behaving cases where the anisotropy of the expansion and the anisotropy of the fluid converge to finite values (include zero) in the late Universe. We have also showed that although the metric we consider is totally anisotropic, the anisotropy of the dark energy is constrained to be axially symmetric, as long as the overall energy momentum tensor possesses zero shear stress.

description: Let $S$ be a semiabelian variety over an algebraically closed field, and let $X$ be an irreducible subvariety not contained in a coset of a proper algebraic subgroup of $S$. We show that the number of irreducible components of $[n]^{-1}(X)$ is bounded uniformly in $n$, and moreover that the bound is uniform in families $X_t$. We prove this by purely Galois-theoretic methods. This proof applies in the more general context of divisible abelian groups of finite Morley rank. In this latter context, we deduce a definability result under the assumption of the Definable Multiplicity Property (DMP). We give sufficient conditions for finite Morley rank groups to have the DMP, and hence give examples where our definability result holds.

description: With the two-fold goal of incorporating more in-depth undergraduate scholarship and increasing a sense of community within a new asynchronous online (Covid-Era) format, I transformed my Women in Music course into a gratifying student experience that culminated in unique academic findings. This General Education course covers women in music, both historically and culturally, with nods to areas like gender studies, social justice, and media bias. In its revised form, after building a knowledge base through assigned readings and reflective discussions, the course guides students toward constructing their own lens and tools for analyzing a major musical work of art by a woman musician. The past two semesters were devoted to exploring Beyoncé’s 2016 Lemonade album and film in terms of its symbolism, overall message, intent as a feminist work of art, personal meaning and value, and model of representation, particularly for students attending an HBCU. Students investigated themes and the musical methods used to convey them, as they also explored their own personal connections to those themes. Through sharing their insights and finding common ground, these classmates assimilated their song analyses into a comprehensive digital artifact, ultimately contributing their distinctive voice to the scholarship on Lemonade’s significance. This venture has revealed a scope of possibilities for including undergraduates in course-based research endeavors. Students with limited expertise can still offer their perceptions and experiences, especially within a communal medium like music, all of which lead toward expanding their views. Most importantly, when students' contributions are validated, they feel empowered.

The development of the Pediatric Motivation Scale for children in rehabilitation : a pilot study
Creators: name: Tatla, Sandeep K.
Publisher: name: University of British Columbia
Year: 2014

description: BACKGROUND: Motivation, a key factor influencing pediatric rehabilitation outcomes, is rarely measured in clinical settings and limited research has explored this construct. Currently, no scale exists with which to measure motivation during rehabilitation from a child’s perspective. PURPOSE: To review evidence about the effects of motivational interventions in children and youth with acquired brain injury (ABI) and to examine the application of Self Determination Theory (SDT) in the rehabilitation context. Based upon tenets of SDT, the aim of this pilot research was to develop an instrument, the Pediatric Motivation Scale (PMOT), to assess motivation from a child’s perspective. METHODS: This study involved two phases. Phase 1 established the PMOT content validity through: a) literature reviews related to motivation in ABI, SDT, and motivation measures; and b) expert feedback from 12 clinicians providing rehabilitation to children who have sustained either acquired brain injury (ABI) or orthopedic injury (OI). During Phase 2, the PMOT was field tested with 12 children with ABI, 9 children with OI, and 20 healthy children serving as controls. Face validity, response process, test-retest reliability, and internal consistency were examined. In addition, convergent validity was explored by comparing therapists' observations of the child's motivation, using the Pediatric Volitional Questionnaire (PVQ). Pearson Product Moment correlations were used to analyze sub-scale correlations, test-retest reliability, and the relationship between the PMOT and the PVQ; Cronbach's alpha was used to measure internal consistency. RESULTS: Literature review revealed a need for the development of valid and reliable measures of motivation in rehabilitation. Preliminary psychometric evaluation of the PMOT indicates strong internal consistency for the scale as a whole (α = .96) and for the subscales (α =.79 to .91). The PMOT was moderately correlated with the PVQ in the rehabilitation subsample (r=.71, p<.01); however, no correlation was found in the healthy subsample (p>.05). Test-retest reliability was excellent (r=.97). CONCLUSIONS: This study provides strong preliminary evidence for psychometric properties of the PMOT for use with children in rehabilitation post ABI or OI. Future research is recommended to build upon these pilot findings for the ongoing development of this scale.

description: We consider convex programming problems with integrality constraints that are invariant under a linear symmetry group. To decompose such problems we introduce the new concept of core points, i.e., integral points whose orbit polytopes are lattice-free. For symmetric integer linear programs we describe two algorithms based on this decomposition. Using a characterization of core points for direct products of symmetric groups, we show that prototype implementations can compete with state-of-the-art commercial solvers, and solve an open MIPLIB problem.

description: Let σ\otimesπ be a supercuspidal representation of SO(2n) \times GL(2n) over a p-adic field with π selfdual, where SO(2n) stands for a quasisplit even special orthogonal group. In order to study its normalized parabolic induction to SO(6n), Goldberg and Shahidi defined a pairing R between the matrix coefficients of σ and π which controls the residue of the standard intertwining operator. The elliptic part of R is conjectured to be related to twisted endoscopic transfer. Based on Arthur's endoscopic classification and Spallone's improvement of Goldberg-Shahidi program, we will verify some of their predictions for general n, under the assumption that π does not come from SO(2n+1).

description: Aufgrund der hohen Variabilität des Plasmaspiegels von Voriconazol hat sich im intensivmedizinischen Bereich im Verlauf der letzten Jahre vermehrt die Anwendung eines therapeutischen Drug Monitoring (TDM) durchgesetzt, um toxische oder subtherapeutische Spiegel zu vermeiden. Im Rahmen der vorliegenden Arbeit sollte evaluiert werden, inwiefern die routinemäßige Anwendung eines TDM mit einem klinischen Nutzen einhergeht. Weiter sollte der Einfluss erhöhter und erniedrigter Voriconazol-Spiegel untersucht werden. Hierzu wurden insgesamt 123 digitale Patientenakten aus den Jahren 2006 bis einschließlich 2013 ausgewertet. Alle Patienten wurden für mindestens fünf Tage mit Voriconazol auf der internistischen Intensivstation der Universitätsklinik Magdeburg behandelt. Während bei 92 (74,8%) Patienten (TDM-Gruppe) Voriconazol-Spiegel gemessen wurden, erfolgte bei den restlichen 31 (25,2%) Patienten (Kontrollgruppe) keine Bestimmung. Trotz einer kränkeren TDM-Gruppe, welche einen signifikant höheren SAPS-II-Score und signifikant häufiger die Diagnose eines septischen Schocks aufwies, fand sich ein deutlicher Trend zu einer geringeren Letalität. Es zeigte sich weiter eine hohe Varibilität des Voriconazol-Spiegels. Nur 48.9% der Patienten wiesen zum Zeitpunkt der ersten Spiegelmessung einen Spiegel innerhalb des therapeutischen Bereichs auf. Die Patienten mit einem Voriconazol-Spiegel unterhalb des therapeutischen Bereichs wiesen eine signifikant längere ITS-Verweildauer (p=0,001) sowie eine signifikant längere Beatmungstherapie (p=0,003) auf. Die Ergebnisse dieser Arbeit unterstützen somit die rountinemäßige Anwendung eines TDM von Voriconazol im intensivmedizinischen Bereich.

I suggest they might choose someone who matches them on race, country of family origin, gender, culture, or research topic of interest to name a few possibilities. I have been amazed at the responses. One student chose a Black astronomer who is still active in his field, and wrote to him explaining why he felt his discoveries should appear in the textbook. The astronomer sent back a very nice letter of response which he allowed the student to share with the class. Another identified and researched a prominent Vietnamese astronomer, while another found someone to identify with on the basis of gender identity. I was honestly surprised at the positive response. Students will write a short reflection on their projects as well for their final portfolios and I fully expect to have a few who felt this was a highlight of the course. Several have already mentioned that they really didn't think they would find anyone like them in the field, and their podcasts and videos are enlightening for me as well.

description: Erythropoetin (EPO) ist ein Wachstumsfaktor, der seit langem in der Anämietherapie eingesetzt wird. Studien der letzten 20 Jahren bewiesen zusätzlich einen gewebeprotektiven Effekt. Vermutet wird eine Hemmung der Apoptose über die Inhibition der permeability transition pore (PTP). Unsere Arbeit beschäftigt sich mit der Frage, ob dieser Effekt nur über den gewebeprotektiven EPO-Rezeptor (innate repair receptor - IRR) zu erzielen ist, ober ob es möglicherweise eine direkte Bindungsstelle von EPO an der PTP gibt. Hierzu führten wir Sauerstoffverbrauchs-, Membranpotential- und Schwellungsmessungen an Rattenhirn- und Rattenlebermitochondrien durch. Weder mit Human- oder Ratten-EPO noch mit dem modifizierten Epoetin alfa oder dem EPO-Derivat ARA 290 ließ sich eine reproduzierbare Wirkung auf die PTP nachweisen. Effekte auf den Sauerstoffverbrauch, die Schwellung und das Membranpotential ließen sich auf die zur Stabilisierung und Konservierung hinzugefügten Zusatzstoffe Na-Citrat (Human-EPO) und Polysorbat 80/20 (Epoetin alfa) zurückführen. Hieraus ergibt sich die Frage, wie bedenklich eine Anwendung von Epoetin alfa und Human-EPO sowohl im klinischen Umfeld als auch im Rahmen von Studien ist.

description: Coinciding with the coronation of King George V, the 1911 Festival of Empire at the Crystal Palace in Sydenham aimed to increase mutual understanding and goodwill across imperial Britain. For many, it would have provided their first insight of the extent their nation’s empire. This paper focusses on the representation of New Zealand on this imperial stage. The dominions were represented by stand-alone pavilions that were modelled as two-thirds scale versions of their respective parliament buildings. These timber and plaster simulacra presented imposing exteriors that enclosed large interior exhibition spaces. An electric railway journeyed around the pavilions passing static dioramas showing aspects of colonial life, while in the afternoons a Pageant of Empire presented successive scenes of English and imperial history. One instalment of these re-enactments included the signing of the Treaty of Waitangi of 1840 and a finale showing peoples of empire paying homage to Britannia. Despite good intentions, things did not run smoothly; New Zealand’s exhibits were late arriving, and its interior display within the pavilion and the exterior dioramas provoked criticism. A Te Arawa performance group from New Zealand’s central North Island, led by Makereti, Maggie Papakura, journeyed to Britain to take part in the show. After British officials declared their village on the Crystal Palace grounds to be a fire risk, they walked off. Nevertheless, of all the features associated with New Zealand at that time in London, these Māori performers appear to have attracted the greatest interest. Events at the festival reveal a complicated attitude towards the empire and inter-colonial relations. To a large extent this was set aside when the empire joined as one in the First World War; however, despite this unity of purpose, traces of this ambivalence would persist.
ON DEMAND: Making Large Classes Feel Small with Learning Communities

description: In connection with my presentation for the Showcase Session on "Creating Community and a Sense of Belonging in Your Course," this On Demand presentation will be discuss using learning communities in large classes – especially online asynchronous classes - to foster a sense of community and connection. This is a strategy I used this year when I combined my 4 sections of English 302 into one large Blackboard shell. I created learning communities within the larger class to give students the small-class experience. Doing so improved discussion board participation and peer review, as group members demonstrated a higher level of investment and engagement. Students also reported feeling more supported in navigating the course and their assignments. This On Demand presentation will include strategies for forming groups (deciding on size, characteristics for group formation, logistics of group formation), how to use the groups during the semester, and a little bit of the feedback from students on how being a part of a learning community impacted their experience of the course.

Field-induced collective spin-exciton condensation in a quasi-2D dx2-y2-wave heavy electron superconductor

description: The origin of the spin resonance observed in CeCoIn5 with Inelastic Neutron Scattering is subject to debate. It has been shown recently that in this heavy electron compound at low temperature an instability to a ground state with coexisting dx2 -y2 -wave superconductivity and Spin Density Wave (SDW) order in a magnetic field is a corollary of the consideration of a collective spin excitation mode in a quasi-2D dx2 -y2 -wave Pauli-limited superconductor. This provides a natural scenario for the occurence of the puzzling high-field-low-temperature phase highlighted in CeCoIn5 . We present perspectives on this ground state transition and propose directions for future experiment.

description: A quantum walk is a time-homogeneous quantum-mechanical process on a graph defined by analogy to classical random walk. The quantum walker is a particle that moves from a given vertex to adjacent vertices in quantum superposition. Here we consider a generalization of quantum walk to systems with more than one walker. A continuous-time multi-particle quantum walk is generated by a time-independent Hamiltonian with a term corresponding to a single-particle quantum walk for each particle, along with an interaction term. Multi-particle quantum walk includes a broad class of interacting many-body systems such as the Bose-Hubbard model and systems of fermions or distinguishable particles with nearest-neighbor interactions. We show that multi-particle quantum walk is capable of universal quantum computation. Since it is also possible to efficiently simulate a multi-particle quantum walk of the type we consider using a universal quantum computer, this model exactly captures the power of quantum computation. In principle our construction could be used as an architecture for building a scalable quantum computer with no need for time-dependent control.

description: International Graduate students at INTO Mason take courses that help them transition into the American academy as well as a multi-disciplinary research writing course that shows them the conventions of writing in their specific disciplines. This assignment touches on many different goals at once. The students must not only interact with their subject librarians at Mason, but also be able to discuss their topics with their librarians and be able to articulate their ideas. This assignment occurs at the point in the semester when students are beginning to formulate their research questions so they can do more targeted research. The students have to be able to fully articulate their ideas and how they work in concert in order to ask for help in identifying articles or chapters to review to support those ideas. This is the assignment sheet for the meeting, annotated to show the research behind its inception.

How to compute the Frobenius-Schur indicator of a unipotent character of a finite Coxeter system
Creators: name: Marberg, Eric
Publisher: name: arXiv
Year: 2012
Subjects: subject: Representation Theory (math.RT)

description: For each finite, irreducible Coxeter system $(W,S)$, Lusztig has associated a set of "unipotent characters" $\Uch(W)$. There is also a notion of a "Fourier transform" on the space of functions $\Uch(W) \to \RR$, due to Lusztig for Weyl groups and to Broué, Lusztig, and Malle in the remaining cases. This paper concerns a certain $W$-representation $\varrho_{W}$ in the vector space generated by the involutions of $W$. Our main result is to show that the irreducible multiplicities of $\varrho_W$ are given by the Fourier transform of a unique function $ε: \Uch(W) \to \{-1,0,1\}$, which for various reasons serves naturally as a heuristic definition of the Frobenius-Schur indicator on $\Uch(W)$. The formula we obtain for $ε$ extends prior work of Casselman, Kottwitz, Lusztig, and Vogan addressing the case in which $W$ is a Weyl group. We include in addition a succinct description of the irreducible decomposition of $\varrho_W$ derived by Kottwitz when $(W,S)$ is classical, and prove that $\varrho_{W}$ defines a Gelfand model if and only if $(W,S)$ has type $A_n$, $H_3$, or $I_2(m)$ with $m$ odd. We show finally that a conjecture of Kottwitz connecting the decomposition of $\varrho_W$ to the left cells of $W$ holds in all non-crystallographic types, and observe that a weaker form of Kottwitz's conjecture holds in general. In giving these results, we carefully survey the construction and notable properties of the set $\Uch(W)$ and its attached Fourier transform.

description: Conventional approaches to cosmology in supergravity assume the existence of multiple sectors that only communicate gravitationally. In principle these sectors decouple in the limit Planck mass to infinity. In practice such a limit is delicate: for generic supergravities, where sectors are combined by adding their Kahler functions, the separate superpotentials must contain non-vanishing vacuum expectation values supplementing the naive global superpotential. We show that this requires non-canonical scaling in the naive supergravity superpotential couplings to recover independent sectors of globally supersymmetric field theory in the decoupling limit Planck Mass to infinity.
