description: Applying exact QCD sum rules for the baryon charge and energy-momentum we demonstrate that if nucleons are the only degrees of freedom of nuclear wave function, the structure function of a nucleus would be the additive sum of the nucleon distributions at the same Bjorken x = AQ^2/2(p_Aq)< 0.5 up to very small Fermi motion corrections if x>0.05. Thus the difference of the EMC ratio from one reveals the presence of non-nucleonic degrees of freedom in nuclei. Using exact QCD sum rules we show that the ratio R_A(x_p,Q^2) used in experimental studies, where x_p = Q^2/2q_0 m_p deviates from one even if a nucleus consists of nucleons with small momenta only. Use of the Bjorken x leads to additional decrease of R_A(x,Q^2) as compared to the x_p plots. Coherent contribution of equivalent photons into photon component of parton wave function of a nucleus unambiguously follows from Lorentz transformation of the rest frame nucleus Coulomb field. For A~200 photons carry ~0.0065 fraction of the light momentum of nucleus almost compensates the difference between data analysis in terms of Bjorken x and x_p. Different role of higher twist effects for Q^2 probed at electron and muon beams is emphasized. Direct observations of large and predominantly nucleonic short-range correlations in nuclei pose a serious challenge for most of the models of the EMC effect for x>0.6. The data are consistent with a scenario in which the hadronic EMC effect reflects fluctuations of inter nucleon interaction due to fluctuations of color distribution in the interacting nucleons. The dynamic realization of this scenario is the model in which the 3q (3qg) configurations with x > 0.5 parton have a weaker interaction with nearby nucleons, leading to suppression of such configurations giving a right magnitude of the EMC effect. The directions for the future studies and challenging questions are outlined.
description: The sign in the relation of x_Bj and x_p is corrected and the following discussion is adjusted accordingly. Discussion of the higher twist effects is added

description: Economical solar energy conversion to electricity can be boosted by the discovery of fundamentally new photovoltaic mechanism, and a suitable system to realize it with commonly available materials like iron (Fe) and nickel (Ni). This paper reports the observation of photovoltaic effect on a molecular spintronics device, composed of magnetic tunnel junction (MTJ) and organometallic molecular clusters (OMCs). A prefabricated MTJ with exposed side edges, after enabling the bridging of OMC channels between its two ferromagnetic films, exhibited following phenomenon (i) dramatic increase in exchange coupling, (ii) 3-6 orders current suppression and (iii) photovoltaic effect. This paper focuses on the photovoltaic effect. Control experiments on isolated ferromagnetic films suggested that OMCs neither affected the magnetic properties nor produced any photovoltaic effect; photovoltaic effect was only observed on the ferromagnetic films serving as magnetic electrodes in a MTJ. Present paper invites further investigation of the similar photovoltaic effect on other combinations of MTJs and promising magnetic molecules, like single molecular magnets, organometallic clusters and porphyrins. This research can lead to mass producible and economical spin photovoltaic devices.

description: In der vorliegenden Studie wurden Probanden mit postlingual unilateralem Hörverlust, die in der Universitätsklinik Magdeburg behandelt wurden, eingeschlossen. Jeweils 7 Probanden mit Single-Sided Deafness waren auf der linken beziehungsweise rechten Seite mit einem Cochleaimplantat versorgt. Für ein erfolgreiches Hörverstehen ist unter anderem die kortikale Sprachverarbeitung, die bei der Mehrheit der Menschen vorwiegend in der linken Gehirnhälfte lokalisiert ist, entscheidend. Anhand von Verhaltensdaten der Probanden und EEG-Daten wurde die Auswirkung der CI-Implantationsseite auf das Hörverstehen von Tönen und Sprache ermittelt. Die Ergebnisse zeigen, dass beide CI-Gruppen bei CI-Sprachstimulation signifikant geringere Trefferquoten und verlängerte Reaktionszeiten im Vergleich zu anderen Bedingungen aufweisen. Hinsichtlich der EEG-Daten zeigen linksseitig versorgte SSD-CI-Träger ein ähnliches Amplitudenverhalten wie Normalhörende. Hingegen weisen rechtsseitig versorgte SSD-CI-Träger im Durchschnitt geringere Amplituden als Normalhörende auf. Zwischen beiden CI-Gruppen zeigen sich keine wesentlichen Unterschiede hinsichtlich der N100-Amplituden. Auffällig ist eine Latenzverschiebung bei Sprachstimulation, wobei CI-Träger bei CI-Sprachstimulation längere N100-Latenzen als Normalhörende vorweisen. Unterschiede zwischen den beiden CI-Gruppen bestehen hierbei nicht. Bei Sprachstimulation des normalhörenden Ohres rechtsseitig versorgter SSD-CI-Träger zeigt sich zudem ein verändertes EEG-Muster. Zusammenfassend deuten die Ergebnisse auf einen möglichen Vorteil der links- verglichen mit rechtsseitigen SSD-CI-Trägern hinsichtlich dem Hörverstehen komplexer Sprachstimuli.

description: Psychologisches Training bezieht sich auf die systematische und regelmäßige Anwendung mentaler Techniken, um psychologische Fertigkeiten zu erlernen, die darauf abzielen die Leistungsfähigkeit und das Wohlbefinden zu fördern. In dieser Arbeit werden in fünf Studien neue psychologische Trainings dargestellt, die einem Blended Learning Ansatz folgend eine App mit Workshops kombinieren. Jede Studie umfasst eine Outcome- und eine Prozessevaluation, die sich jeweils auf den konkreten Fall bezieht. Die Outcome-Ergebnisse lassen keine monokausalen Schlussfolgerungen zu. Alle Prozessergebnisse zeigen eine geringe Trainingszeit mit den Studien-Apps. Deshalb wird das sozial-kognitive Prozessmodell des Gesundheitsverhaltens herangezogen, um verschiedene Möglichkeiten (z.B. individualisierte Handlungs- und Bewältigungspläne) für zukünftige Interventionen abzuleiten, die eine optimale App-Nutzung ermöglichen könnten.
description: Psychological skills training refers to the systematic and consistent practice of psychological skills that facilitate performance and personal well-being. This thesis presents five newly developed app-based blended psychological skills trainings executed using an app and workshops in real-life settings. Each study included an outcome and a process evaluation focusing on the particular rather than the general, incorporating the researchers’ theoretical-based reflection. The outcome results are inconsistent and do not allow monocausal conclusions to be drawn. All process results revealed that app user engagement is a recurrent challenge. Thus, the health action process approach is used to derive multifaceted suggestions (e.g., individualized action and coping plans) for future app-based blended intervention design enabling optimal app usage.

description: We theoretically explore the annihilation of vortex dipoles, generated when an obstacle moves through an oblate Bose-Einstein condensate, and examine the energetics of the annihilation event. We show that the gray soliton, which results from the vortex dipole annihilation, is lower in energy than the vortex dipole. We also investigate the annihilation events numerically and observe that the annihilation occurs only when the vortex dipole overtakes the obstacle and comes closer than the coherence length. Furthermore, we find that the noise reduces the probability of annihilation events. This may explain the lack of annihilation events in experimental realizations.

description: We study a particular type of subcritical Galton--Watson trees, which are called non-generic trees in the physics community. In contrast with the critical or supercritical case, it is known that condensation appears in certain large conditioned non-generic trees, meaning that with high probability there exists a unique vertex with macroscopic degree comparable to the total size of the tree. Using recent results concerning subexponential distributions, we investigate this phenomenon by studying scaling limits of such trees and show that the situation is completely different from the critical case. In particular, the height of such trees grows logarithmically in their size. We also study fluctuations around the condensation vertex.

Regulation of plant defense responses downstream of PAMP receptors
Creators: name: Nitta, Yukino
Publisher: name: University of British Columbia
Year: 2019

description: The primary layer of plant immunity is pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI). In PTI, when pattern recognition receptors (PRRs) recognize PAMPs, a highly regulated, rapid downstream signaling response such as activation of mitogen-activated protein (MAP) kinases, production of ROS and defense gene expression is initiated. My study involves the identification of MAP kinases activated in PTI and regulation of PTI responses by E3 ubiquitin ligases. In Arabidopsis thaliana, MPK3, MPK4, and MPK6 are activated upon PAMP treatment. However, previous studies suggest that there are more MAP kinases activated upon PAMP treatment. To identify the additional MAP kinases phosphorylated upon PAMP perception, transgenic plants expressing candidate MPKs with a ZZ-FLAG double tag (approx. 17kD) were generated in Col-0 background. Western blot analysis identified three MAP kinases, MPK1, MPK11 and MPK13 that are phosphorylated upon PAMP treatment. To identify E3 ligases involved in PTI, E3 ligases whose transcripts are up-regulated upon PAMP treatment were selected for our study. Transgenic lines overexpressing candidate E3 ligases were assayed for deficiencies in PTI. Overexpression of U6, one of the selected E3 ligases, lead to severe reduction of flg22-induced reactive oxygen species (ROS) production and increased susceptibility to Pseudomonas syringae pv. tomato (P.s.t.) DC3000 hrcC-. Furthermore, when U6 was overexpressed in BIK1 (a positive regulator of PTI)-HA transgenic plants, there was a decrease in BIK1-HA protein expression, leading to the hypothesis that BIK1 may be a potential target of U6. Overall, my thesis contributes to a better understanding of the signaling and negative regulation of PTI. Advancing our knowledge in plant immunity leads to the potential of its use in agriculture and plant protection.

description: Die zentrale Zielstellung der Studie ist eine differenzierte Analyse weiblicher Biographien im akademischen Mittelbau, speziell von Habilitandinnen, unter dem Gesichtspunkt, welchen Habitus sie sich aneignen, um mitspielen zu können auf dem akademischen Parkett. Die qualitative Studie arbeitet auf 2 Analyseebenen mit narrativen Interviews. Aus einem Sample von 18 Interviews werden 2 Interviews tiefer analysiert. Sie stehen für unterschiedliche Pole einer variantenreichen Skala, wie Frauen zu Mitspielerinnen in der Wissenschaft werden. Dabei nutze ich u.a. Pierre Bourdieus Konzepte des Habitus und von Wissenschaft als sozialem Feld. Zusammenfassend lassen sich der Typus `Wissenschaft als Lebensform´ und `Leben in 2 Welten´ gegenüberstellen. Weiterführend kann so gefragt werden, ob die Karriere von Frauen nicht mehr an die Ausbildung eines Anerkennungshabitus gebunden ist und wie Risse in die männliche Herrschaft im Feld der Universität gekommen sind.
description: The central objective of the present study is a differentiated analysis of female biographies in academic mid-level positions, focussing on female habilitation candidates. The central question is which habitus they acquire in order to perform successfully in the academic field. The work is designed as a qualitative study that works on two levels of analysis with narrative interviews. From a sample of 18 interviews, 2 interviews are analyzed more thoroughly. They stand for different ends in a scale of how women become active players in university contexts. Among other theories, Pierre Bourdieus concepts of habitus and science as a social field are applied. In summary, the types `science as a way of life´ and `life in two worlds´ can be differentiated. In addition, the question is whether women´s careers are no longer linked to the development of a recognition habit. A further question is, how changes in male dominance in the university field have come about.
Spiritismus in Deutschland : Andrew Jackson Davis zwischen Republikanismus, freier Religion und Wissenschaft im langen 19. Jahrhundert

description: Nees von Esenbeck, Gregor Konstantin Wittig und Georg von Langsdorff übersetzten die Werke von Andrew Jackson Davis‘ und schrieben diese für die Etablierung des Spiritismus in Deutschland maßgeblich in die deutschsprachigen Debatten ein. Das Projekt untersucht Verwobenheiten zwischen Akteuren und Programmen, die in der Geschichtsschreibung disparat behandelt, marginalisiert oder gegeneinander ausgespielt werden: Spiritismus vs. Wissenschaft, Religion, Politik und Gesellschaft. Dies hat Folgen für die religionshistorische Erschließung. Vor allem produzieren Konnotationen systematisch eine Verdrängung der Inhalte spiritistischer Ansätze im 19. Jahrhundert bzw. eine isolierte (Wieder-)Einschreibung, werden die dazugehörigen Akteure oder Aspekte ihres Werkes in der Geschichtsschreibung teils ganz aus dem jeweils konzipierten Erklärungsmuster für die Entwicklung der Moderne als nicht-fortschrittlich oder anachronistisch ausgeschieden.
description: With focus on the translation of the work of Andrew Jackson Davis by Nees von Esenbeck, Gregor Konstantin Wittig and Georg von Langsdorff the project explores the nexus between intellectual programs and their protagonists, which are typically treated separately or contrasted with one another in established historiography: spiritualism versus science, religion, and political conflict. Placed at the fringes of the history of religion, spiritualism is typically represented in contrast to established religion, science, and society. This has consequences for the historical analysis. Connotations systematically marginalize the contents of spiritualist thought in the 19th century or (re-)introduce the same in an isolated manner. Moreover, related protagonists of the 19th century, or certain aspects of their work, are either marginalized or wholly discarded as not progressive or anachronistic by the respective patterns for explaining the development of modernity.
Univalence for inverse diagrams and homotopy canonicity

description: We describe a homotopical version of the relational and gluing models of type theory, and generalize it to inverse diagrams and oplax limits. Our method uses the Reedy homotopy theory on inverse diagrams, and relies on the fact that Reedy fibrant diagrams correspond to contexts of a certain shape in type theory. This has two main applications. First, by considering inverse diagrams in Voevodsky's univalent model in simplicial sets, we obtain new models of univalence in a number of (infinity,1)-toposes; this answers a question raised at the Oberwolfach workshop on homotopical type theory. Second, by gluing the syntactic category of univalent type theory along its global sections functor to groupoids, we obtain a partial answer to Voevodsky's homotopy-canonicity conjecture: in 1-truncated type theory with one univalent universe of sets, any closed term of natural number type is homotopic to a numeral.

The qualitative Study was conducted in 2 memory clinics in Saxony Anhalt/ Germany. The study is based on 21 narrative interviews of primary caregivers who giving care to relatives with dementia. A Grounded Theory framework was chosen. Against the background of late diagnosis, the access to the services of memory clinics is difficult. In summary of the study results, the intensification of public relations work by memory clinics appears to be a decisive moment to pave the access to their care structures for caring relatives and dementia patients in a timely manner during the course of the disease.
Transcriptomic consequences of RNA processing disruption via a novel CDC-like kinase inhibitor
Creators: name: Funnell, Tyler
Publisher: name: University of British Columbia
Year: 2016

description: RNA splicing is a process by which introns are excised from precursor mRNA. Variations in the segments removed — and the resulting mRNA molecule — may result in gene transcripts with differing and even opposing functions. The mechanisms involved in RNA splicing are tightly regulated, the disruption of which has been implicated in several human diseases including cancer. This presents the RNA splicing machinery as a potential therapeutic target. However, the effects of systematic splicing modulation through pharmaceutical intervention remain under explored. A thorough understanding of splicing can be investigated through controlled disruption of the molecular machinery. The Takeda Pharmaceutical Company Limited (Osaka, Japan) has recently developed a novel compound that inhibits the CDC-like family of kinases, which regulate key splicing factors. Although splicing inhibitors have already been published, their effects on the RNA splicing landscape have not been systematically described. The creation of a novel splicing inhibitor presents the opportunity to perform a methodical analysis of transcriptomic response to RNA processing inhibition using modern RNA sequencing and analysis methods. It is demonstrated, using the Takeda compound, that restricting the function of CDC-like kinases perturbs RNA splicing in both malignant and normal cells in a dose dependent manner. Post-treatment changes in splicing patterns revealed that these changes are mainly due to inefficient recognition of RNA splice sites. Splicing factors were among the earliest responders to treatment, indicating splicing autoregulatory mechanisms are sensitive to changes in splicing efficiency. Downstream effects were seen as dose-dependent changes in gene expression regulation, and down-regulated genes were enriched for splicing factors. Treatment also resulted in increased generation of conjoined gene transcripts — RNA molecules transcribed from at least two different genes, likely caused by transcriptional read-through. This revelation points to a previously undescribed role for CDC-like kinases in RNA processing.

Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: This teaching and learning artifact describes how a final presentation assignment for a master’s-level course in education was adapted to a synchronous online format modeled after an interactive conference poster session. Students each created a virtual poster using the OSCAR template to share the research projects they completed for the course and presented them to their peers in Zoom breakout rooms. The class was divided into three groups so that students could move between presentations, view classmates’ posters, listen to a brief explanation, ask questions, and provide feedback; both attendees and presenters filled out short peer and self-evaluations using Google Forms. This format facilitated more interaction and engagement than each student presenting to the whole class, which is particularly important in online instruction. The artifact includes instructions provided to students beforehand, the poster template, a description of logistics during the presentation session, peer and self-evaluation surveys, and an instructor rubric as well as several example posters and student feedback about the activity.

Both statements follow from Fomin and Zelevinsky's Laurent phenomenon. As an application we give a criterion for a cluster algebra to be a factorial algebra. This can be used to construct cluster algebras, which are isomorphic to polynomial rings. We also study various kinds of upper bounds for cluster algebras, and we prove that factorial cluster algebras coincide with their upper bounds.

description: Creating or adapting experiential, face-to-face, hands-on exercises for an online learning format is not always straightforward or easy. As part of an undergraduate new product development course re-design for online learning, six new engaging, experiential exercises were developed and utilized in spring 2021. The exercises address different modules and learning goals in the course, and they also allow students to practice different skills in an LMS (Blackboard) environment - such as using discussion board forums, uploading videos and photos, sharing links, and providing peer-to-peer feedback. The exercises are called – paper airplane, opposites attract, job to be done, squiggle birds, and taglines challenge. Some of the exercises are individual exercises, and some are peer/team-based. The exercises were created to work under pandemic conditions, and allow students to use items readily found in their home environments. For example, the paper airplane exercise that addresses the learning goal of practicing rapid prototyping and learning to use an online whiteboard, asks students to use one sheet of paper to create a paper airplane, record and submit a video of a flight, and to answer and reflect on the learning process. These exercises may also be modified for use across different courses and subject matter and work in hybrid and in-person learning environments. The poster will showcase each of the six exercises, and provide suggestions on how they can be adapted across disciplines and learning formats. Participants should be inspired to think creatively on how to incorporate fun, active learning exercises into their own courses.

description: Stickstoff (N) ist das wichtigste mineralische Element; der übermäßige Einsatz von Stickstoffdüngern hat ernsthafte Auswirkungen auf die planetarischen Grenzen. Es ist zwingend erforderlich, das Management der Stickstoffdüngung zu verbessern und die Effizienz der Stickstoffnutzung in der landwirtschaftlichen Pflanzenproduktion zu erhöhen. In dieser Studie wird die N-Aufnahme von Winterweizen als physiologisches Merkmal bewertet, um die genetische Variation von 100 neueren Elitelinien (angepasste Linien) und 100 (nicht angepasste Linien), die vor der "grünen Revolution" eingeführt wurden, zu nutzen. Durch die getrennte Untersuchung der kurz- und langfristigen NH4+- und NO3-Aufnahmeraten bei mikromolaren oder millimolaren N-Konzentrationen und bei ausreichender oder geringer N-Versorgung wird deutlich, dass bei den angepassten Linien insbesondere Tobak höhere Aufnahmeraten aufweist als Rockefeller. Insgesamt deutet diese Studie darauf hin, dass allelische Variationen in AMT1.2 ein zusätzliches Beta-Faltblatt in der Proteinstruktur bilden, das signifikant mit einer hochaffinen Aufnahmekapazität für Ammonium einhergeht. Ebenso könnte mit fortschreitendem N-Mangel eine starke Hochregulierung insbesondere von AMT3.1 für die höhere Ammoniumaufnahmekapazität in Tobak verantwortlich sein.
description: Nitrogen (N) is the most important mineral element; the excess use of N fertilizers has a serious impact on planetary boundaries. It is mandatory to improve N fertilization management and increase N use efficiency in agricultural plant production. In this study as a physiological trait, two winter wheat panels N uptake rates are assessed to exploit genetic variation from 100 recent elite lines (adapted lines), and 100 (unadapted lines) released before the ‘green revolution’ lines. Also, by examining short and long-term NH4+ and NO3- uptake rates separately at micromolar or millimolar N concentrations and under adequate or low N supply, represent that in adapted lines specifically Tobak has higher uptake rates than Rockefeller. Altogether, this study indicates that allelic variation in AMT1.2 forms an additional beta-sheet in protein structure significantly coincided with high-affinity uptake capacity for ammonium. Likewise, with progressing N deficiency strong upregulation esp. of AMT3.1 may be responsible for higher ammonium uptake capacity in Tobak.
A minimally-invasive MEMS drug delivery device for the treatment of prostate cancer
Creators: name: Zachkani, Payam
Publisher: name: University of British Columbia
Year: 2015

description: We have developed a cylindrical shape magnetically-actuated MEMS drug delivery device for localized prostate cancer treatment. The device is small enough for implantation through a needle with minimally invasive procedures with potentially fewer side effects compared with full prostate removal. This method of implantation will be similar to brachytherapy, a standard procedure to implant radioactive seeds inside the prostate through a needle. The drug delivery device consists of a drug reservoir, a PDMS membrane, a magnetic block and housing. Docetaxel (DTX), an anti-proliferative drug, is deposited in the reservoir in solid form. The reservoir is then filled with fluids to form a saturated drug solution. When an external magnetic field is applied, it attracts the magnetic block towards the positive field gradient and causes the membrane to deflect. As a result, DTX is discharged from the reservoir, through a laser-drilled aperture on the membrane and into the housing. The housing has a 10 mm long opening which allows the released drug to diffuse to the surrounding tissues while it would prevent the tissues from touching the thin membrane. We have achieved a 1.8 fold increase of the actuating distance and a 3.6 fold increase in the magnetic force compared to the state-of-the-art magnetically-actuated drug delivery devices under the same actuation parameters. We have also demonstrated device implantation with a needle into swine bladder tissue and successful drug release of the device in the tissue.

ON DEMAND: Cumulative Writing Assignments: Benefits for Students and Instructors
Creators: name: Wood, Jennifer
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: How often have students exclaimed in exasperation, “I hate writing!”? Writing can provoke high anxiety-levels among our students, especially in the wake of the pandemic and/or when a large percentage of their final grade hinges on a single writing assignment. This is particularly, though certainly not exclusively, the case for Mason’s international/multilingual student population. This brief presentation will explain the rationale for assigning cumulative writing assignments that culminate in a final paper students build throughout the semester, and will offer example assignments that can be tailored to specific courses. Having the opportunity to draft, workshop, revise, and expand ideas not only demystifies the writing process—it also cultivates a generative, explorative learning environment by allowing students to experiment with ideas in drafts without fear of receiving a lower letter-grade. The rationale for such writing assignments derives from the principle that when anxieties are mitigated, students are able to learn more effectively. Furthermore, this approach offers a manageable workload for instructors: completion grades can be offered for smaller-stakes components (outlines, lists of evidence, bibliographies), while more comprehensive commentary and letter-grades can be provided on elements like thesis statements, and peer-review can be employed for early drafts. Although scaffolding a writing assignment is not original in itself, some innovative process-based activities this presentation will offer include: the use of new technologies, like Hypothesis, to assist students in brainstorming ideas; suggestions for collaborative support activities, including in-class debates where students assess each others’ evidence to support their thesis statements and pre-final-draft conference-style presentations, where students have the opportunity to present their writing and answer questions from their peers about their final writing projects before they complete the final draft. While I will use a brief example of a cumulative writing assignment from my Shakespeare courses as a case-study, the assignment I outline in this presentation is easily translatable to any course or topic that involves a major writing project as part of its curriculum—and to courses as wide-ranging as online (synchronous or asynchronous), hybrid, or face-to-face, and even spanning undergraduate to graduate levels. Participants will be able to create meaningful writing assignments for their students with a workload that doesn’t overwhelm either students or instructors.

Normal Bundle of Rational Curves and Waring Decomposition
Creators: name: Bernardi, Alessandro
Publisher: name: arXiv

description: The problem of determining the splitting of the normal bundle of rational space curves has been considered in the 80s in a series of papers by Ghione and Sacchiero and by Eisenbud and Van de Ven. With our approach we are able to obtain results for curves embedded in $\bbP^m$ for $m\geq 3$ and we find an interesting interplay between the Waring decomposition of binary forms and the splitting of the normal bundle.
ON DEMAND: Maximizing Engagement in Live Virtual Activities

Publisher: name: Innovations in Teaching & Learning Conference Proceedings

description: Have you ever assigned a task or activity for your learners to complete individually or in a virtual breakout room? Maybe you assigned a series of discussion questions that were supposed to lead to a deliverable or a task that required using a virtual collaboration space and everyone ended up confused. As an instructor or trainer, you cannot be everywhere at once—particularly in virtual environments. So, how do you maximize activity engagement and avoid confusion during live virtual classes and trainings when you cannot be in every breakout room at the same time or reasonably field questions from numerous individuals or groups? A simple solution can be ensuring effective modeling of the activity before you start. Sometimes clear instructions are simply not enough. Effective modeling ensures that the assigned live virtual activity runs smoothly and does not leave you scrambling or your learners confused. In this video, participants will be shown various ways to virtually model an activity prior to starting it. Strategies will also be shared on how to check for understanding of live virtual activities before they begin, and how to evaluate their success upon completion. Lastly, participants will be encouraged to apply what they have learned to their role as an instructor, trainer, or anyone leading a virtual meeting.

Droplet-shaped waves: Causal finite-support analogs of X-shaped waves

description: A model of steady-state X-shaped wave generation by a superluminal (supersonic) pointlike source infinitely moving along a straight line is extended to a more realistic causal scenario of a source pulse launched at time zero and propagating rectilinearly at constant superluminal speed. In the case of infinitely short (delta) pulse, the new model yields an analytical solution, corresponding to the propagation-invariant X-shaped wave clipped by a droplet-shaped support, which perpetually expands along the propagation and transversal directions, thus tending the droplet-shaped wave to the X-shaped one.

ON DEMAND: Leading for Change: A Customizable Writing Experience
Creators: name: Johnston, Joyce
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: "Leading for Changes" addresses any faculty or staff member who will use writing and visual presentation skills to empower students to identify social or professional issues that are important to them, learn more about those issues, then focus on practical ways to affect change. “Leading for Change” provides assignments, skill builders, readings and short videos to effect change on a significant social or professional issue important to each student. One Composition Program assignment + 1 research project + 1 visual presentation + 2 support activities = five customizable components that can be adapted to fit multiple disciplines and variable time constraints. The five major components are (1) analyzing personal traits, values and ethics, (2) conducting investigative research on stakeholder groups that students can join upon graduating from George Mason (3) applying for employment or acceptance by a selected group, (4) combining models of professional and leadership skills to function effectively in that context and (5) visually presenting the selected leadership model(s) that will most effectively advocate for social or professional change from within. The presenter provides multiple suggestions for combining and recombining the components, teaching materials as above and coordination of the modules to Mason Impact, Mason Core, and the proposed ARIE course for Fall 2021, Foundations for Building a Just Society.

Groups associated to $II_1$-factors

description: We extend recent work of the first named author, constructing a natural Hom semigroup associated to any pair of II$_1$-factors. This semigroup always satisfies cancelation, hence embeds into its Grothendieck group. When the target is an ultraproduct of a McDuff factor (e.g., $R^ω$), this Grothendieck group turns out to carry a natural vector space structure; in fact, it is a Banach space with natural actions of outer automorphism groups.

Improved Maximum Entropy Analysis with an Extended Search Space

description: The standard implementation of the Maximum Entropy Method (MEM) follows Bryan and deploys a Singular Value Decomposition (SVD) to limit the dimensionality of the underlying solution space apriori. Here we present arguments based on the shape of the SVD basis functions and numerical evidence from a mock data analysis, which show that the correct Bayesian solution is not in general recovered with this approach. As a remedy we propose to extend the search basis systematically, which will eventually recover the full solution space and the correct solution. In order to adequately approach problems where an exponentially damped kernel is used, we provide an open-source implementation, using the C/C++ language that utilizes high precision arithmetic adjustable at run-time. The LBFGS algorithm is included in the code in order to attack problems without the need to resort to a particular search space restriction.

W boson polarization measurement in the ttbar dilepton channel using the CDF II Detector
Creators: name: CDF Collaboration
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: We present a measurement of $W$ boson polarization in top-quark decays in $t\bar{t}$ events with decays to dilepton final states using $5.1 {\rm fb^{-1}}$ of integrated luminosity in $p\bar{p}$ collisions collected by the CDF II detector at the Tevatron. A simultaneous measurement of the fractions of longitudinal ($f_0$) and right-handed ($f_+$) $W$ bosons yields the results $f_0 = 0.71 ^{+0.18}_{-0.17} {\rm (stat)} \pm 0.06 {\rm (syst)}$ and $f_+ = -0.07 \pm 0.09 {\rm (stat)} \pm 0.03 {\rm (syst)}$. Combining this measurement with our previous result based on single lepton final states, we obtain $f_0 = 0.84 \pm 0.09 {\rm (stat)} \pm 0.05 {\rm (syst)}$ and $f_{+} = -0.16 \pm 0.05 {\rm (stat)} \pm 0.04 {\rm (syst)}$. The results are consistent with standard model expectation.
