description: Nervous systems of all organisms are remarkably complex. This complexity is a reflection of the great diversity of the nervous systems’ basic units, the neurons. There is a large variety of different neuron types that differ in their morphology, function and their underlying molecular composition. Even though neurons are very diverse, they all share common features, namely cellular projections (axons and dendrites) and synapses. Genes expressed in the entire nervous system, called pan-neuronal genes, encode the molecular correlates to these common features. Although a lot is known about how specific transcription factors, Terminal Selectors (TS), specify the different neuronal types by co-regulating neuron type specific gene expression, much less is understood about the regulatory programs that control the expression of pan-neuronal genes. Addressing this question is key to understanding how neuronal fate is determined. In this thesis I have explored the regulatory logic of pan-neuronal genes in C. elegans. After performing an extensive analysis of the cis-regulatory regions of a set of pan-neuronal genes, defined in this study, I have found that the expression of these genes is regulated in a modular and redundant manner. Modular because for a given pan-neuronal gene there are different cis-regulatory elements controlling its expression in different sets of neurons; redundant because there are more than one transcription factors that can activate expression of a given pan-neuronal gene in the same neuron types. Interestingly I have found that Terminal Selectors can redundantly regulate pan-neuronal gene expression together with other transcription factors. I have also identified the HOX genes as one example of such factors that act redundantly with Terminal Selectors to directly regulate pan-neuronal gene expression in the C. elegans ventral nerve cord neurons. Neuronal gene expression regulatory programs therefore fall into two fundamentally distinct categories. Neuron type specific genes are generally controlled by discrete and non-redundantly acting regulatory inputs, while pan-neuronal gene expression is controlled by diverse, coincident and seemingly redundant regulatory inputs.

description: In this paper we investigate the problem of a long self-avoiding polymer chain immersed in a random medium. We find that in the limit of a very long chain and when the self-avoiding interaction is weak, the conformation of the chain consists of many ``blobs'' with connecting segments. The blobs are sections of the molecule curled up in regions of low potential in the case of a Gaussian distributed random potential or in regions of relatively low density of obstacles in the case of randomly distributed hard obstacles. We find that as the strength of the self-avoiding interaction is increased the chain undergoes a delocalization transition in the sense that the appropriate free energy per monomer is no longer negative. The chain is then no longer bound to a particular location in the medium but can easily wander around under the influence of a small perturbation. For a localized chain we estimate quantitatively the expected number of monomers in the ``blobs'' and in the connecting segments.

description: Location: Dewberry Hall This activity is based on the concept of Customer Journey Maps that have been researched and used in Marketing to better understand customer experience within a domain of interest, such as cooking or travel (Yachin 2018; Lemon and Verhoef 2016). In the Marketing learning/education literature, the concept has also been applied to make data-driven marketing more understandable and interesting (Micheaux and Bosio 2018). A Customer Journey Map is a step-by-step walk through a particular activity in the life of the customer. The map addresses customer thoughts, feelings, motivations, and actions as related to the focal domain. The activity can also be extended for teambuilding and reflection among a diverse population of students. Working in a classroom or in a distance learning setting, students work in pairs, each student interviewing each other on their experience in a domain relevant to a course (undergraduate or graduate) or more generally to encourage students to learn about each other and reflect on their own experiences (e.g., first year experience at Mason, experience of growing up in U.S. or another country, etc.), including on what could have made a better experience. After the interviews are complete, students create a visual representation of the other studentâs journey that includes what was uncovered â the thoughts, feelings, motivations, and actions. The student shares their representation of the journey with the student that underwent the journey for feedback. Engaging in this activity students learn to appreciate each otherâs perspective and experiences that may be different from their own.

Our survey asked students to think of a positive instruction experience and answer questions about that experience. Though it included several questions which are similar to a teaching evaluation survey, our respondents were not asked to rate their instructor; instead, they reported on their engagement in class and their instructorâs practices.

description: During nervous system development, thousands of distinct cell types are generated and assembled into complex circuits that control all aspects of animal cognition and behavior. Understanding what these diverse cells are, how they are generated, and what they do in the context of circuits and behavior form the fundamental efforts of the field of neuroscience. In this thesis, I investigate how the genomic organization of regulatory elements informs specific patterns of gene expression in the nervous system. In particular, I examine how distinct combinations of transcription factors interpret information encoded in the genome to control global gene expression programs in a cell-type-specific manner.
      In Chapter Two, I describe the establishment of a developmentally inspired transcriptional programming system to generate spinal and cranial motor neurons directly from mouse embryonic stem cells. Programmed motor neurons acquire general characteristics that mirror their in vivo counterparts, providing a robust system for studying cell fate specification in the nervous system. Combinatorial expression of cell-type-specific programming factors informs context-dependent enhancer binding and acquisition of appropriate cell-type-specific molecular and functional properties.
      In Chapter Three, I take advantage of this robust, experimentally accessible system to probe the chromatin-level organization and regulatory principles controlling specificity of motor neuron gene expression programs. Motor neuron genes are controlled by multiple distantly distributed enhancer constellations stretched across large regulatory domains. Using this motor neuron specification model, I discovered a unique regulatory organization controlling gene expression in the nervous system, whereby neuronal genes are controlled from uniquely complex regulatory domains acting over large distances.
      In Chapter Four, I extrapolate on the insights gained from studying motor neurons at a single point in time to investigate the dynamics of the regulatory environment during neuronal maturation. We demonstrate that enhancers are highly dynamic even after postmitotic specification. The dynamic nature of enhancers is dependent on combinatorial binding with new transcriptional cofactors.
      Overall, my results suggest that neuronal gene expression programs within a single cell type are regulated in a highly dynamic fashion by a complex set of enhancers. I propose that during development the immense cellular complexity of the nervous system is established and maintained by correspondingly complex repertoire of enhancers.

description: Polycrystalline samples of layered pnictogen diselenide NdO0.8F0.2Sb1-xBixSe2 (x = 0 to 0.8) were successfully synthesized by solid-state reactions. Electrical resistivity in the synthesized samples was systematically decreased with an increase in Bi content x. Crystal structure analysis using synchrotron X-ray diffraction suggests that insulator to metal transition upon Bi doping correlates with anomalous change in c-axis length and/or corrugation in conducting layer. The emergence of superconductivity under high pressure is demonstrated using diamond anvil cell (DAC) with boron-doped diamond electrodes, for x = 0.3 and 0.7 as the representative samples. For Sb-rich one (x = 0.3), we observed a superconducting transition with Tconset = 5.3 K at 50 GPa, which is the first-ever report of the superconductivity in layered SbCh2-based (Ch: chalcogen) compounds. The Tconset of x = 0.3 increased with increasing pressure and reached 7.9 K at 70.8 GPa, followed by the gradual decrease in Tc up to 90 GPa. For Bi-rich one (x = 0.7), a superconducting transition with Tconset = 5.9 K was observed at 43.5 GPa, which is the almost comparable to that of x = 0.3; besides, upper critical field (Hc2) is evaluated to be ~10 T for x = 0.7, which is higher than that of x = 0.3 (Hc2 = 6.7 T at 50 GPa).

Opportunities for using pulp mill residues in mine remediation

Year: 2020

description: The pulp and paper industry produces organic wastes such as primary and secondary biosolids from water treatment, as well as bottom and fly ashes from energy production through combustion of biomass. We are investigating these residues for reuse in mine remediation; such as to support sulphate reducing bacteria and remove zinc and cadmium with secondary biosolids as the carbon and nutrient source, and treatment of acid mine drainage using green liquor and fly ash. Use of these residues is limited by transportation costs depending on the proximity of pulp mills and mine sites to each other. To expand the reuse of pulp mill residues, there is the opportunity to increase their value through fairly straight forward thermal, physical and or chemical transformations that functionalize them in order to sequester and recover specific values. In this paper, we provide the example where we recovered selenium for potential recycling from simulated mine impacted water using functionalized residues. Areas where this can be applied include the Elk Valley, East Kootenays, and the Cariboo region of British Columbia.

description: The purpose of this note is to establish, in a categorical manner, the universality of the Geroch-Kronheimer-Penrose causal boundary when considering the types of causal structures that may profitably be put on any sort of boundary for a spacetime. Actually, this can only be done for the future causal boundary (or the past causal boundary) separately; furthermore, only the chronology relation, not the causality relation, is considered, and the GKP topology is eschewed. The final result is that there is a unique map, with the proper causal properties, from the future causal boundary of a spacetime onto any ``reasonable" boundary which supports some sort of chronological structure and which purports to consist of a future completion of the spacetime. Furthermore, the future causal boundary construction is categorically unique in this regard.

Moreover, it is proved that the group ring R(G) is FP-injective (resp. weakly quasi-Frobenius) if and only if the ring R is FP-injective (resp. weakly quasi-Frobenius) and the group G is locally finite.

description: We give a proof of the KAM theorem on the existence of invariant tori for weakly perturbed Hamiltonian systems, based on Thirring's approach for Hamiltonians that are quadratic in the action variables. The main point of this approach is that the iteration of canonical transformations on which the proof is based stays within the space of quadratic Hamiltonians. We show that Thirring's proof for nondegenerate Hamiltonians can be adapted to Hamiltonians with degenerate twist. This case, in fact, drastically simplifies Thirring's proof.

description: Location: JC Room G During the 2018 fall semester, GMU School of Business instructors found that an interdisciplinary approach through the integration of literature and business produced new insights among our students on ethical decision-making in two courses we feature in the Business Foundations Area. Specifically, we learned that these narratives enhanced student understanding of the complex ethical questions surrounding stakeholder involvement and sustainable development decisions. In Business and Society, a course designed to introduce students to the complex relationships among large US corporations and a broad range of stakeholders, we experienced good results incorporating the novel March by Congressman John Lewis. Through its depiction of the social and emotional life of a young African American living in the segregated South, this narrative provides alternative representations of the modern business enterprise and what it represented to minority Americans in terms of doctrines of prosperity and economic opportunity We incorporated a discussion and written assignment of the first of his three graphic novels in a class session we feature on the ethics of relationships between businesses and consumers. Many students were surprised from this first-person narrative of the extent of the limitations African-Americans faced as consumers and how recently these were in place in the United States. Other students gained new insights into the impact of the boycotts John Lewis and colleagues organized. In a second course, Business 200: Global Environment of Business, we introduced on a trial basis the novel How to Get Filthy Rich in Rising Asia by Mohsin Hamid to present competing views of ethical gray areas as they pertain to sustainable development in the developing world. Previously, we had focused exclusively on the visionary tale of sustainable development in the developed world as presented in the book Cradle to Cradle by Michael Braungart and William McDonough. We found that comparing and contrasting the ethical decision-making in a developing world economy with that of a developed world exposed students to visions and values of others within the context of their own aspirations and values. In addition, we noticed that the introduction of the second book enriched the dialogue between our US-born and foreign-born studentsâmany of whom spent childhood years in a developing-world settingâconcerning what constitutes ethical decision making, what sustainable development goals can be addressed in the short term and long term, and how business leader decision-making and obligations might align and differ in the two diverse settings.

description: Light emission from solid-state quantum emitters is inherently prone to environmental decoherence, which results in an inhomogeneous line broadening and in the deterioration of photon indistinguishability. Here we employ photon correlation Fourier spectroscopy (PCFS) to study the temporal evolution of such a broadening for the biexciton and exciton emission in resonantly driven GaAs quantum dots. Differently from previous experiments, the time scales we probe range from a few nanoseconds to milliseconds and, simultaneously, the spectral resolution we achieve can be as small as 2 $μ$eV. We find pronounced differences in the temporal evolution of the two lines, which we attribute to differences in their homogeneous linewidth and sensitivity to charge noise. We then analyze the effect of irradiation with additional white light, which reduces blinking at the cost of enhanced charge noise. Due to its robustness against experimental imperfections and its high temporal resolution and bandwidth, PCFS outperforms established spectroscopy techniques, such as Michelson interferometry. We discuss its practical implementation, its limitations, and the possibility to use it to estimate the indistinguishability of consecutively emitted single photons for applications in quantum communication and photonic-based quantum information processing.

description: We propose a theoretical framework to study the cooperative behavior of dynamically coupled oscillators (DCOs) that possess dynamical interactions. Then, to understand synchronization phenomena in networks of interneurons which possess inhibitory interactions, we propose a DCO model with dynamics of interactions that tend to cause 180-degree phase lags. Employing an approach developed here, we demonstrate that although our model displays synchronization at high frequencies, it does not exhibit synchronization at low frequencies because this dynamical interaction does not cause a phase lag sufficiently large to cancel the effect of the inhibition. We interpret the disappearance of synchronization in our model with decreasing frequency as describing the breakdown of synchronization in the interneuron network of the CA1 area below the critical frequency of 20 Hz.

description: Protein coronas on nanoparticles (NPs) affect their physicochemical properties, cellular uptake, and toxicity, and have been described extensively. To date, studies of the occurrence of small molecule (metabolite) coronas are limited. We sought to determine whether a metabolite corona forms on NPs, using high-sensitivity metabolomics combined with a model system for freshwater ecotoxicology (Daphnia magna feeding on Chlorella vulgaris). Using amino-functionalized polystyrene NPs (NH2-pNPs), we showed the impact of this material on Daphnia feeding to provide a rationale for the detailed molecular investigations. We then employed a targeted LC-MS/MS approach for sodium dodecyl sulfate (SDS) as an analog to signaling molecules known to occur in our freshwater model system and optimized a corona extraction method for this representative metabolite. Next, we performed an untargeted discovery-based metabolomics study – using high-sensitivity nanoelectrospray direct infusion mass spectrometry (DIMS) – to enable an unbiased assessment of the metabolite corona of NH2-pNPs in the freshwater model system. Our results demonstrate that SDS was successfully recovered from NH2-pNPs, confirming that the extraction protocol was fit-for-purpose. Untargeted DIMS metabolomics reproducibly detected 100 s of small molecule peaks extracted from NH2-pNPs exposed to conditioned media from the D. magna–C. vulgaris model system. Attempts to annotate these extracted metabolites, including by using van Krevelen and Kendrick Mass Defect plots, indicate a diverse range of metabolites that were not clustered into any particular class. Overall we demonstrate the existence of an ecologically relevant metabolite corona on the surface of NPs through application of a high-sensitivity, untargeted mass spectrometry metabolomics workflow.

description: Location: Dewberry Hall We developed and implemented a 1 Credit undergraduate course offering Mental Health First Aid training and certification. MHFA training is proven effective in assisting people through mental health crises and challenges, while early identification and treatment can lessen the impact of mental illness. Understanding a student's own mental illness and knowing how to help another student through a crisis improves retention and satisfaction with the college experience. Offering courses that address personal mental health concerns demonstrates the University's commitment to student well-being. Participants will be able to identify strategies that encourage students to explore their own understanding of mental health disorders and how to help a person experiencing a mental health crisis. Participants will be able to identify a course that they can recommend to students to enhance student learning about mental health disorders and hope for recovery.

description: Analysing negotiation communication in an electronic setting is a challenging task. During recent years, many researchers have tried to explain the differences between successful and failed negotiation applying a great variety of approaches, ranging from linguistic analyses over phase identification to psychological analyses of the discourse during a negotiation. The aim of this paper is to provide the foundation to analyse negotiation communication with a machine learning approach. To this end, a review of existing and related research is given, the applicability of machine learning techniques on electronic negotiations is discussed and, in a first step of the process, different methods of feature selection are reviewed to find the most applicable technique in the setting given.

description: The paper addresses the problem of designing radar detectors more robust than Kelly's detector to possible mismatches of the assumed target signature, but with no performance degradation under matched conditions. The idea is to model the received signal under the signal-plus-noise hypothesis by adding a random component, parameterized via a design covariance matrix, that makes the hypothesis more plausible in presence of mismatches. Moreover, an unknown power of such component, to be estimated from the observables, can lead to no performance loss. Derivation of the (one-step) GLRT is provided for two choices of the design matrix, obtaining detectors with different complexity and behavior. A third parametric detector is also obtained by an ad-hoc generalization of one of such GLRTs. The analysis shows that the proposed approach can cover a range of different robustness levels that is not achievable by state-of-the-art with the same performance of Kelly's detector under matched conditions.
Using Graphic Organizers To Support All Students

description: Location: JC Room F Students in the classroom have multiple learning modalities: auditory, tactile, visual. The use of Graphic Organizers reaches all three and helps the student focus on the "need to know material" prior to class to enrich the contact time of F2F classes. The use of Graphic Organizers is not new nor is it unique in any standard way. What is unique is the results of students learning outcomes when Graphic Organizers are used by instructors. Research has shown that this learning aid helps all students who use them and that they are more likely to achieve excellence and retention of the material. This is particularly present in courses with technical material such as accounting or food safety. Graphic Organizers are a form of study guide. What makes them different is that they use shapes, diagrams, relationship models and much more to emphasize the material in multi modalities of audio (reading/lecture), visual (displays of the information), and tactile (having to complete them prior to class lecture and then have on hand for editing/enhancement during lecture). This use of graphic organizers helps students better understand and apply knowledge of key learning outcomes that is often included in hundreds of pages of text reading in a short form of 3 to 4 pages.

description: Die elektronische Rechnungsverarbeitung gewinnt in Europas Unternehmen, staatlichen Verwaltungen und Organisationen an Bedeutung. Die internen Geschäftsprozesse und die Prozesse unter Geschäftspartnern ändern sich signifikant. Die elektronische Rechnungsverarbeitung besitzt enorme Einsparpotenziale in Milliardenhöhe: trotzdem ist der Anteil elektronisch versendeter B2B oder B2G Rechnungen in Summe in vielen Staaten Europas vergleichsweise gering. Dieser Aufsatz hat das Ziel, den aktuellen Stand der Forschung im Umfeld der elektronischen Rechnungsverarbeitung zu analysieren. Die Ergebnisse und Erkenntnisse zeigen, dass die Forschung diverse Themen und Fragen untersucht, allerdings existieren bisher aber weder eine einheitliche und integrative Sicht, noch befriedigende Theorien, Modelle oder Handlungsempfehlungen für Europa.

description: Advertising seems to be the major stream for generating revenue with online content. Therefore, it is crucial for online content providers to create heavy traffic on their pages. Recommender systems have already been evaluated on their positive impact in e-commerce settings. In our evaluation we show that personalized recommendation as well change the user behavior and improve the relevant economic KPIs for content providers. To show these effects we put up a model that inter-relates all components of an advertising-based revenue stream. We formulate a set of hypotheses on those components, which can be influenced by recommender systems: exposure and stickiness, indicating customer engagement, as well as the content portfolio that impairs the appealed user base. The hypotheses are tested in a study that is being conducted based on a real-world data set from a German newspaper.

description: Long-term management of selenium and other parameters, specifically, innovative treatment technologies applied to final effluents, has been established at coal mining operations throughout North America. A holistic approach to site-wide selenium and nitrate management is being developed at Conuma Coal’s Brule Mine, in northeastern British Columbia, in the context of the post-closure phase of the mine life cycle. The purpose of this study is to improve upon the application of semi-passive treatment system comprising a biochemical reactor (BCR). Conuma Coal’s objective for the system is to reduce selenium, nitrate, and other parameters. The BCR will be used as a tool to aid in the on-going improvement of water quality leading to the goal of compliance with provincial permits and proposed national effluent limits. The basic design and initial construction of the BCR treatment system took place in 2015, with a recent upgrade in 2017. A sampling strategy for effluent monitoring has been established to evaluate the system. Based upon a year of accumulated operating data, parameter concentrations have trended downwards. To date, the BCR has demonstrated success: selenium has been removed in the range 50-90%, while nitrates have been removed in the range 65-99%. Several challenges have been encountered in implementing the system, yielding a number of lessons learned, including: sequencing and flow control are crucial to the proper functioning of the BCR system; sediment curtains help to reduce sediment load to the aerator; and, raised edges help to reduce surface water run-off entering BCR system. Future work relating to the dynamics of resident microbial communities is being planned.

description: To an arbitrary directed graph we associate a row-finite directed graph whose C*-algebra contains the C*-algebra of the original graph as a full corner. This allows us to generalize results for C*-algebras of row-finite graphs to C*-algebras of arbitrary graphs: the uniqueness theorem, simplicity criteria, descriptions of the ideals and primitive ideal space, and conditions under which a graph algebra is AF and purely infinite. Our proofs require only standard Cuntz-Krieger techniques and do not rely on powerful constructs such as groupoids, Exel-Laca algebras, or Cuntz-Pimsner algebras.

description: In diesem Artikel wird, basierend auf den etablierten Modellen von Dabbish und Kraut sowie Franz, ein Modell zur Darstellung der Auslöser von Informationsüberlastung durch E-Mails abgeleitet. Die Ausgangsmodelle werden um zusätzliche Auslöser erweitert, welche im Rahmen einer Literaturanalyse hochrangiger IS Journals und IS Conferences identifiziert wurden. Das entwickelte Modell beinhaltet 14 divergierende Ursachen für die Informationsüberlastung durch E-Mails in den Kategorien „Merkmale der Informationen“, „Technische Merkmale“ und „Persönliche Merkmale“. Darüber hinaus beeinflussen die vier Moderatorvariablen „Alter“, „Geschlecht“, „E-Mail-Client“ und „Zugangsart“ die Wirkung der Auslöser auf die Informationsüberlastung durch E-Mails. Zur späteren Validierung des Modells wurden für die Variablen entsprechende Konstrukte identifiziert bzw. abgeleitet.
