Scholarly Digital Storytelling: Authentic Learning In The Classroom And Beyond
Creators: name: Schrum, Kelly
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2019

description: Location: Dewberry Hall In scholarly digital storytelling, students produce digital stories based on academic research. Interviews with students and faculty from 22 different institutions across five countries focused on the ways in which participation in scholarly digital storytelling influences studentsâ academic research, scholarly communication, and digital skills. Preliminary results indicate significant impact on student engagement, motivation, skills, and application of those skills beyond the classroom. Faculty similarly report authentic learning, student engagement, and skill development as well as their own learning and engagement in the teaching process. Scholarly digital storytelling is flexible and can be integrated into many learning environments, from mini-assignments to full-semester projects.

description: Multiple space-borne cosmic ray detectors have detected line-like features in the electron and positron spectra. Most recently, the DAMPE collaboration reported the existence of such a feature at 1.4 TeV, sparking interest in a potential dark matter origin. Such quasi-monochromatic features, virtually free of any astrophysical background, could be explained by the annihilation of dark matter particles in a nearby dark matter clump. Here, we explore the consistency of producing such spectral features with dark matter annihilation from the standpoint of dark matter substructure statistics, constraints from anisotropy, and constraints from gamma-ray emission. We demonstrate that if indeed a high-energy, line-like feature in the electron-positron spectrum originates from dark matter annihilation in a nearby clump, a significant or even dominant fraction of the dark matter in the Solar System likely stems from the clump, with dramatic consequences for direct dark matter searches.

description: This thesis introduces a new strategy to fabricate single molecular transistor by utilizing the covalent chemistry to reconnect the molecule with the electroburnt graphene nanogap. We studied the effect of coupling chemistry and molecular length on the efficiency of reconnection between the molecule and the graphene. With this technique, we are also able to observe the Coulomb Blockade phenomenon, which is a characteristics of single-electron transistors. The high yield and versatility of this approach augur well for creating a new generation of sensors, switches, and other functional devices using graphene contacts. This thesis also introduces a new type of organic single-crystal p-n heterojunction inspired from the ball-and-socket shape-complementarity between fullerene and contorted dibenzotetrathienocoronene (c-DBTTC). We studied the influence of temperature, pressure, and time on the self-assembly process of contorted dibenzotetrathienocoronene on the as-grown fullerene crystals. We also utilized fluorescence microscopy to investigate the charge transfer in this type of p-n heterojunction. Finally, this thesis introduces one-dimensional and two-dimensional programming in solid-state materials from superatom macrocycles. We find that the linkers that bridges the two superatoms determine the distance and electronic coupling between the two superatoms in the macrocycle, which in turn determines the way they self-assembled in the solid-state materials.
      The thesis is composed of four chapters. The first chapter introduces why we are in terested in molecular transistors and new functional materials, and what has been done so far. The second chapter described the approach we developed to assemble single molecule into circuits with graphene electrodes. The third chapter details the method to fabricate the organic single-crystal C60-DBTTC p-n heterojunction, which is of great importance to understand their charge transfer process. The last chapter introduced a new series of superatom macrocycles and their self-assembly into solid-state materials with electron acceptor tetracyanoethylene.
Uranium diffusion in soils and rocks

description: The results of a study undertaken to review the process of diffusion of uranium in soils and rocks are presented and discussed. After some background on the geochemistry of uranium and the different definitions for the diffusion coefficient in porous media, i.e. D*, De, Da, values of D*, De, and/or Da from the literature are summarized, analyzed and discussed. Diffusion of uranium in compacted bentonite is shown to increase semilog linearly with an increase in porosity (decrease in dry density), and appears to be significantly slower than that in other soils, probably due to the existence of semipermeable membrane behavior and interparticle/intraparticle diffusion as an attenuation mechanism. The effect of attenuation is shown to increase the variability in Da relative to that in either D* or De, and the variability in D*, De, and Da is shown to be greater in compacted bentonite than in unfractured biotitic granite, likely due to a more homogeneous pore structure and a lesser attenuation capacity for the biotitic granite. Overall, the typical preference for reporting only Da values is shown to severely restrict the usefulness of the literature on the subject.

Limit theorems for some time dependent expanding dynamical systems

Year: 2019
Subjects: subject: Dynamical Systems (math.DS)

description: In this paper we will prove various probabilistic limit theorems for some classes of distance expanding sequential dynamical systems (SDS). Our starting point here is certain sequential complex Ruelle-Perron-Frobenius (RPF) theorems which were proved in \cite{book} and \cite{ASIP me} using contraction properties of a complex version of the projective Hilbert metric developed in \cite{Rug}. We will start from the growth rate of the variances of the underlying partial sums. This is well understood in the random dynamics setup, when the maps are stationary, but not in the SDS setup, where various growth rates can occur. Some of our results in this direction rely on certain type of stability in these RPF theorems, which is one of the novelties of this paper. Then we will provide general conditions for several classical limit theorems to hold true in the sequential setup. Some of our general results mostly have applications for composition of random non-stationary map, while the conditions of the other results hold true for general type of SDS. In the latter setup, results such as the Berry-Esseén theorem and the local central limit theorem were not obtained so far even for independent but not identically distributed maps, which is a particular case of the setup considered in this paper.

Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2019

description: Location: Dewberry Hall Drawing from both personal experience and research, this poster will exhibit how inquiry-based learning in hybrid spaces can be a particularly good fit. A graduate, hybrid course, Teaching Hidden History, will be used as a case study. My colleagues and I at the Roy Rosenzweig Center for History and New Media here at Mason developed this course in 2015. It was taught in the summer of 2015 and then again in 2016 and since then we have conducted numerous student interviews to gain insights into the students' learning processes. Students in the course each created an online learning module designed to teach history and historical inquiry skills. The course was taught over 9 weeks with the first 5 weeks conducted in person. During this time students chose their module topics, learned research skills, digital skills, and read scholarship on using digital methods to teach history. In the second iteration of the course material related to explicitly teaching collaboration was added. The next 3 weeks of the course were online and asynchronous. Students did not work in isolation, however. They collaborated with each other in assigned collaborative groups in the first iteration and in collaborative partnerships in the second iteration. They also met with professors either in person or virtually. From interviews it was clear that careful scaffolding and supported collaboration were key to successful projects. The poster will share student testimony and provide project examples.

description: It is suggested that the motion of pedestrians can be described as if they would be subject to `social forces'. These `forces' are not directly exerted by the pedestrians' personal environment, but they are a measure for the internal motivations of the individuals to perform certain actions (movements). The corresponding force concept is discussed in more detail and can be also applied to the description of other behaviors. In the presented model of pedestrian behavior several force terms are essential: First, a term describing the acceleration towards the desired velocity of motion. Second, terms reflecting that a pedestrian keeps a certain distance to other pedestrians and borders. Third, a term modeling attractive effects. The resulting equations of motion are nonlinearly coupled Langevin equations. Computer simulations of crowds of interacting pedestrians show that the social force model is capable of describing the self-organization of several observed collective effects of pedestrian behavior very realistically.

description: Location: Dewberry Hall Students today expect to be actively engaged as part of the learning process. They want the opportunity to develop skills required by their future employers, such as problem-solving, collaboration, and building community. Since 2007, escape rooms have become increasingly popular as a form of entertainment and tourist attraction across the globe (Kolar, 2017). Escape rooms engage teams of players in discovering clues, solving puzzles, and accomplishing tasks toward a specific goal in a limited amount of time (Nicholson, 2015). More recently, educators have recognized escape rooms as a game-based learning strategy with the potential to encourage learners “to think differently, unconventionally, and from a new perspective” (Wiemker, Elumir, & Clare, 2015, p. 55). Research indicates that escape games have the potential to build skills such as collaboration, communication, problem-solving, critical thinking, leadership, listening, conflict resolution, and varied social dynamics (Pan, Lo, & Neustaedter, 2017). Additionally, escape rooms can be themed and address any content area, making them appropriate for classroom settings. To capitalize on the escape room model in education, Breakout EDU developed an immersive learning games platform with access to open source materials to support the creation of classroom escape challenges and scenarios for learners of any age. Breakout EDU also developed and sells physical escape kits, or "breakout boxes," that include a variety of components such as reprogrammable locks and multilocks, UV lights, invisible ink pens, and a locking box to simulate an escape room environment. The escape room model has gained momentum in P-12 settings (Chambers, 2018), but use in Higher Education is less evident. As teacher educators, we were first introduced to Breakout EDU at a conference on information technology and teacher education where we participated in several escape challenges and experienced the skills promised in the literature on escape rooms. We implemented Breakout EDU challenges in our own practice with similar responses from our students, particularly related to team-building, engagement, and social dynamics. In this workshop, we provide an opportunity for attendees to participate in a team-based Breakout EDU adventure to unlock the promise of escape rooms for Higher Education. Participants will learn how to integrate game-based learning, through the use of Breakout EDU, into their courses. They will become familiar with the resources available and will discuss ideas for how Breakout EDU can be used in their subject matter.

description: In the past five years, single-particle cryo-electron microscopy (cryo-EM) has revolutionized structural biology. Recent advances in detector technology and powerful computational methods now allow images of unprecedented detail to be recorded and structures to be determined at near-atomic resolution. For my PhD studies, I took advantage of this technique to study the structure of uniquely fragmented ribosomes. Ribosomes, are large macromolecular complexes that translate genetic information carried by messenger RNAs (mRNAs) into polypeptide chains. They are the protein production factories of all living cells and are thus involved in virtually all aspects of cellular development and maintenance. By virtue of their core role in the cell, ribosomes share a highly evolutionarily conserved core that carries out the fundamental processes of protein synthesis [1]. However, outside of this core, ribosome composition varies considerably. The main differences among eukaryotic ribosomes are due to rRNA expansion segments (ESs) and variations of ribosomal proteins (r-proteins) [1, 2]. Further, rRNA fragmentation occurring in regions of high variability has been reported in several organisms from bacteria to protozoa, insects, helminths, fish, and surprisingly mammals [3-15]. Recently, the naked mole-rat (Heterocephalus glaber) was discovered to have unusual cleavage sites in its 28S rRNA resulting in the deletion of the major part of the D6 variable region (ES15L) and leaving the two rRNA fragments disconnected [14]. The cleaved 28S rRNA has been associated with the naked mole rat’s increased translational fidelity [14]. The only other known mammals having fragmented rRNA are the tuco-tuco rodent (of the genus Ctenomys) and the degu (in the related genus Octodontomys) [13]. Here we present the high-resolution structures of the naked mole-rat, tuco-tuco, and guinea pig (Cavia porcellus) ribosomes. Guinea pig, which has canonical (non-fragmented) 28S rRNA is used as a rodent model for comparisons to the naked mole-rat and tuco-tuco ribosomes. During my PhD studies, I also looked at another uniquely fragmented ribosome, that of the protozoan parasite, Trypanosoma cruzi (T. cruzi), the causative agent of Chagas disease. The T. cruzi large subunit (LSU) rRNA is assembled from 8 pieces-5S, 5.8S, and six pieces forming jointly the 28S rRNA. Together with my colleagues from Joachim Frank’s and Liang Tong’s research groups, we solved the structure of the T. Cruzi LSU and identified distinctive trypanosome interactions, which allowed us to propose a tentative model for assembly of the large ribosomal subunit (60S) [16, 17].

Single-crystal growth of organic semiconductors and organic electronic applications

Publisher: name: Columbia University
Year: 2012
Subjects: Chemistry

description: This thesis describes single crystal growth of organic semiconductors and their applications in organic electronics. In Chapter 2, a self-assembled monolayer of C60 derivatives with five carboxylic acids was employed to make C60 thin-film transistors. The highly-crystalline C60 monolayer enabled more ordered deposition of C60 thin film, which resulted in higher electrical characteristics when the thin film was used in field-effect transistors (FET). The C60 film with the monolayer was characterized by IR, XPS, and FET measurements. In Chapter 3, organic single crystal FET of rubrene was studied. Graphene was used as an organic electrode instead of conventional gold film. Graphene is a sp2-hybridized carbon crystal which has high conductivity with negligible thickness. These factors are advantageous in organic FET as the graphene-organic interface has no Schottky barrier and structural contact resistance. The FET of rubrene showed much higher hole transport mobility compared to conventional FET using gold electrodes. In Chapter 4, morphology dependence of dibenzotetrathienocoronene (DBTTC) crystal growth on different substrates was studied. Crystal growth of DBTTC on a single-layer graphene surface shows vertical growth of nanowire crystals not observed with other substrates. GIXD was measured to confirm this crystal morphology. Chapter 5 discusses organic solar cells composed of hexabenzocoronene (HBC) and C60 and their improvement by utilizing the co-crystallization effect of these two molecules. In Chapter 6, HBC was fluorinated using two different ring-closing reactions, and their energy difference as well as conformation change was investigated.

description: The possible realization of Majorana fermions as quasiparticle excitations in condensed matter physics has created much excitement. Most recent studies have focused on Majorana bound states which can serve as topological qubits. More generally, akin to elementary particles, Majorana fermions can propagate and display linear dispersion. These excitations have not yet been directly observed, and can also be used for quantum information processing. One route to realizing this is in a line junction between two phase-shifted superconductors coupled to topological surface states. Recent theory indicates that in iron-based superconductors, a particular type of crystalline defect, i.e., a domain wall (DW) between two regions with a half-unit cell shift between them, should create a $π$-phase shift in the superconducting order parameter. Combined with recent data showing topological surface states in FeSe$_x$Te$_{1-x}$ we find that this is the ideal system to realize helical 1D-dispersing Majorana modes. Here we report scanning tunneling spectroscopic (STS) measurements of crystalline DWs in FeSe$_{0.45}$Te$_{0.55}$. By analyzing large-area superconducting gap maps, we identify the gap in the topological surface state, demonstrating that our sample is an effective Fu-Kane proximitized topological system. We further locate DWs across which the atoms shift by half a unit cell. STS data on these DWs reveal a flat density of states inside the superconducting gap, a hallmark of linearly dispersing modes in 1D. This unique signature is absent in DWs in the related superconductor, FeSe which is not in the topological phase. Our combined data are consistent with the observation of dispersing Majorana states at a $π$-phase shift DW in a proximitized topological material.

description: We explore Tate-type conjectures over $p$-adic fields. We study a conjecture of Raskind that predicts the surjectivity of $$ ({\rm NS}(X_{\bar{K}}) \otimes_{\mathbb{Z}}\mathbb{Q}_p)^{G_K} \longrightarrow H^2_{\rm et}(X_{\bar{K}},\mathbb{Q}_p(1))^{G_K} $$ if $X$ is smooth and projective over a $p$-adic field $K$ and has totally degenerate reduction. Sometimes, this is related to $p$-adic uniformisation. For abelian varieties, Raskind's conjecture is equivalent to the question whether $$ {\rm Hom}(A,B)\otimes{\mathbb{Q}}_p \,\to\, {\rm Hom}_{G_K}(V_p(A),V_p(B)) $$ is surjective if $A$ and $B$ are abeloid varieties over $K$. Using $p$-adic Hodge theory and Fontaine's functors, we reformulate both problems into questions about the interplay of $\mathbb{Q}$- versus $\mathbb{Q}_p$-structures inside filtered $(φ,N)$-modules. Finally, we disprove all of these conjectures and questions by showing that they can fail for algebraisable abeloid surfaces.

description: The interaction of a Grand Unification Magnetic Monopole with a nucleon can lead to a barion-number violating process in which the nucleon decays into a lepton and one or more mesons (catalysis of nucleon decay). In this paper we report an experimental study of the effects of a catalysis process in the MACRO detector. Using a dedicated analysis we obtain new magnetic monopole (MM) flux upper limits at the level of $\sim 3\cdot 10^{-16} cm^{-2} s^{-1} sr^{-1}$ for $1.1\cdot 10^{-4} \le |β| \le 5\cdot 10^{-3}$, based on the search for catalysis events in the MACRO data. We also analyze the dependence of the MM flux limit on the catalysis cross section.

description: We extend the recently developed kinematical framework for diffeomorphism invariant theories of connections for compact gauge groups to the case of a diffeomorphism invariant quantum field theory which includes besides connections also fermions and Higgs fields. This framework is appropriate for coupling matter to quantum gravity. The presence of diffeomorphism invariance forces us to choose a representation which is a rather non-Fock-like one : the elementary excitations of the connection are along open or closed strings while those of the fermions or Higgs fields are at the end points of the string. Nevertheless we are able to promote the classical reality conditions to quantum adjointness relations which in turn uniquely fixes the gauge and diffeomorphism invariant probability measure that underlies the Hilbert space. Most of the fermionic part of this work is independent of the recent preprint by Baez and Krasnov and earlier work by Rovelli and Morales-Tecótl because we use new canonical fermionic variables, so-called Grassman-valued half-densities, which enable us to to solve the difficult fermionic adjointness relations.

description: A search for the production of three massive vector bosons in proton-proton collisions is performed using data at $\sqrt{s} = 13$ TeV recorded with the ATLAS detector at the Large Hadron Collider in the years 2015-2017, corresponding to an integrated luminosity of $79.8$ fb$^{-1}$. Events with two same-sign leptons $\ell$ (electrons or muons) and at least two reconstructed jets are selected to search for $WWW \to \ell ν\ell νqq$. Events with three leptons without any same-flavour opposite-sign lepton pairs are used to search for $WWW \to \ell ν\ellν\ell ν$, while events with three leptons and at least one same-flavour opposite-sign lepton pair and one or more reconstructed jets are used to search for $WWZ \to \ell νqq \ell \ell$. Finally, events with four leptons are analysed to search for $WWZ \to \ell ν\ell ν\ell \ell$ and $WZZ \to qq \ell \ell \ell \ell$. Evidence for the joint production of three massive vector bosons is observed with a significance of 4.1 standard deviations, where the expectation is 3.1 standard deviations.

description: We study the Johnson-Segalman (JS) model as a paradigm for some complex fluids which are observed to phase separate, or ``shear-band'' in flow. We analyze the behavior of this model in cylindrical Couette flow and demonstrate the history dependence inherent in the local JS model. We add a simple gradient term to the stress dynamics and demonstrate how this term breaks the degeneracy of the local model and prescribes a much smaller (discrete, rather than continuous) set of banded steady state solutions. We investigate some of the effects of the curvature of Couette flow on the observable steady state behavior and kinetics, and discuss some of the implications for metastability.

description: Session LOCATION: George's (3rd Floor Johnson Center) Experiential learning environments and "learning by doing" are accepted as effective instructional methods. Application in our market research classes immerses students in an authentic project, e.g. studentsâ perceived marketing curriculum needs. The information is used to improve the curriculum and to complete class projects. Some voluntarily do projects for real clients, e.g. The Honey Bee Initiative, Executive and Professional Education, and others. Participants will be able to generalize the authentic learning opportunities to their curriculum.

description: An important issue for rare-event-search experiments, such as the search for dark matter or neutrinoless double beta decay, is to reduce radioactivity of the detector materials and the experimental environment. The selection of materials with low radioactive impurities, such as isotopes of the uranium and thorium chains, requires a precise measurement of surface and bulk radioactivity. Focused on the first one, an alpha-particle detector has been developed based on a gaseous micro-time-projection chamber. A low-alpha mu-PIC with reduced alpha-emission background was installed in the detector. The detector offers the advantage of position sensitivity, which allows the alpha-particle contamination of the sample to be imaged and the background to be measured at the same time. The detector performance was measured by using an alpha-particle source. The measurement with a sample was also demonstrated and the sensitivity is discussed.

Practical Synthesis of Reactive Systems from LTL Specifications via Parity Games

description: The synthesis of reactive systems from linear temporal logic (LTL) specifications is an important aspect in the design of reliable software and hardware. We present our adaption of the classic automata-theoretic approach to LTL synthesis, implemented in the tool Strix which has won the two last synthesis competitions (Syntcomp2018/2019). The presented approach is (1) structured, meaning that the states used in the construction have a semantic structure that is exploited in several ways, it performs a (2) forward exploration such that it often constructs only a small subset of the reachable states, and it is (3) incremental in the sense that it reuses results from previous inconclusive solution attempts. Further, we present and study different guiding heuristics that determine where to expand the on-demand constructed arena. Moreover, we show several techniques for extracting an implementation (Mealy machine or circuit) from the witness of the tree-automaton emptiness check. Lastly, the chosen constructions use a symbolic representation of the transition functions to reduce runtime and memory consumption. We evaluate the proposed techniques on the Syntcomp2019 benchmark set and show in more detail how the proposed techniques compare to the techniques implemented in other leading LTL synthesis tools.
Generalized Quantum Theory in Evaporating Black Hole Spacetimes

description: Quantum mechanics for matter fields moving in an evaporating black hole spacetime is formulated in fully four-dimensional form according to the principles of generalized quantum theory. The resulting quantum theory cannot be expressed in a 3+1 form in terms of a state evolving unitarily or by reduction through a foliating family of spacelike surfaces. That is because evaporating black hole geometries cannot be foliated by a non-singular family of spacelike surfaces. A four-dimensional notion of information is reviewed. Although complete information may not be available on every spacelike surface, information is not lost in a spacetime sense in an evaporating black hole spacetime. Rather complete information is distributed about the four-dimensional spacetime. Black hole evaporation is thus not in conflict with the principles of quantum mechanics when suitably generally stated.

Breakage and reformation of flocs in oil sands tailings slurries

description: Tailings management presents a key challenge in effectively exploiting oil sands resources, since every barrel of bitumen recovered generates two to three barrels of tailings waste. With the recent adoption of Canadian Energy Resources Conservation Board Directive 74, however, this waste can no longer be discharged as-is, but must be dewatered and rendered trafficable within five years of generation. Not only are process tailings targeted for remediation, but also the approximately 700 million m³ of mature fine tailings that have been accumulated over decades of processing and lie in large containment ponds. Chemical strategies for dewatering tailings involve treatment with additives that bind the tailings particles together into larger flocs, with floc size and shape influencing settling rates and compaction. Mechanical operations such as centrifugation or even pipeline transport, however, can break apart flocs, altering their sedimentation and packing behavior. In this research, mature fine tailings were treated with a range of organic flocculants and coagulants to induce floc formation. Floc breakage and reformation were assessed rheologically and by dynamic measurements of particle size distributions.[All papers were considered for technical and language appropriateness by the organizing committee.]
