description: Collisions between cosmic bubbles of different vacua are a generic feature of false vacuum eternal inflation scenarios. While previous studies have focused on the consequences of a single collision event in an observer's past, we begin here an investigation of the more general scenario allowing for many "mild" collisions intersecting our past light cone (and one another). We discuss the general features of multiple collision scenarios and consider their impact on the cosmic microwave background (CMB) temperature power spectrum, treating the collisions perturbatively. In a large class of models, one can approximate a multiple collision scenario as a superposition of individual collision events governed by nearly isotropic and scale-invariant distributions, most appearing to take up less than half of the sky. In this case, the shape of the expected CMB temperature spectrum maintains statistical isotropy and typically features a dramatic increase in power in the low multipoles relative to that of the best-fit $Λ$CDM model, which is in tension particularly with the observed quadrupole. We argue that this predicted spectrum is largely model-independent and can be used to outline features of the underlying statistical distributions of colliding bubbles consistent with CMB temperature measurements.

description: Stress and strain are important factors in determining the mechanical, electronic, and optical properties of materials, relating to each other by the material's elasticity or stiffness. Both are represented by second rank field tensors with, in general, six independent components. Measurements of these quantities are usually achieved by measuring a property that depends on the translational symmetry and periodicity of the crystal lattice, such as optical phonon energies using Raman spectroscopy, the electronic band gap using cathodoluminescence, photoelasticity via the optical birefringence, or Electron Back Scattering Diffraction (EBSD). A reciprocal relationship therefore exists between the maximum sensitivity of the measurements and the spatial resolution. Furthermore, of these techniques, only EBSD and off-axis Raman spectroscopy allow measurement of all six components of the stress tensor, but neither is able to provide full 3D maps. Here we demonstrate a method for measuring the full stress tensor in diamond, using the spectral and optical polarization properties of the photoluminescence from individual nitrogen vacancy (NV) colour centres. We demonstrate a sensitivity of order 10 MPa, limited by local fluctuations in the stress in the sample, and corresponding to a strain of about 10^-5, comparable with the best sensitivity provided by other techniques. By using the colour centres as built-in local sensors, the technique overcomes the reciprocal relationship between spatial resolution and sensitivity and offers the potential for measuring strains as small as 10^-9 at spatial resolution of order 10 nm. Furthermore it provides a straightforward route to volumetric stress mapping. Aside from its value in understanding strain distributions in diamond, this new approach to stress and strain measurement could be adapted for use in micro or nanoscale sensors.

description: Collisions of deformed uranium nuclei provide a unique opportunity to study the spatial dependence of charmonium in-medium effects. By selecting the orientations of the colliding nuclei, different path lengths through the nuclear medium could be selected within the same experimental environment. In addition, higher energy densities can be achieved in U+U collisions relative to Au+Au collisions. In this paper, we investigate the prospects for charmonium studies with U+U collisions. We discuss the effects of shadowing and nuclear absorption on the J/ψ yield. We introduce a new observable which could help distinguish between different types of J/ψ interactions in hot and dense matter.

description: Prion diseases are invariably fatal and highly infectious neurodegenerative diseases affecting humans and animals. The neurodegenerative diseases such as Creutzfeldt-Jakob disease, variant Creutzfeldt-Jakob diseases, Gerstmann-Str$\ddot{a}$ussler-Scheinker syndrome, Fatal Familial Insomnia, Kuru in humans, scrapie in sheep, bovine spongiform encephalopathy (or 'mad-cow' disease) and chronic wasting disease in cattle belong to prion diseases. By now there have not been some effective therapeutic approaches to treat all these prion diseases. Dogs, rabbits and horses were reported to be resistant to prion diseases. By the end of year 2010 all the NMR structures of dog, rabbit and horse prion proteins (X-ray for rabbits too) had been finished to release into protein data bank. Thus, at this moment it is very worth studying the NMR and X-ray molecular structures of horse, dog and rabbit prion proteins to obtain insights into their immunity prion diseases. The author found that dog and horse prion proteins have stable molecular dynamical structures whether under neutral or low pH environments, but rabbit prion protein has stable molecular dynamical structures only under neutral pH environment. Under low pH environment, the stable $α$-helical molecular structures of rabbit prion protein collapse into $β$-sheet structures. This article focuses the studies on rabbit prion protein (within its C-terminal NMR, Homology and X-ray molecular structured region RaPrP$^\text{C}$ (120-230)), compared with human and mouse prion proteins (HuPrP$^\text{C}$ (125-228) and MoPrP$^\text{C}$ (124-226) respectively). The author finds that some salt bridges contribute to the structural stability of rabbit prion protein under neutral pH environment.

description: Appendix 1 and 2 of the preprint chapter, "Management and Storage of 3D Data." Appendices contain the questions and results of the survey conducted by the Management Working Group of the Community Standards for 3D Preservation (CS3DP). The challenge of managing 3D data for long-term preservation is one that many repository managers are grappling with as the technologies for creating 3D products become more accessible. This chapter aims to discuss the unique features of 3D data management and how repository managers are currently wrestling with 3D. Discussion of current data management standards are placed alongside responses collected through an international informational survey of 3D data managers and creators in the winter of 2018-2019, and concludes with recommendations for 3D data preservation. The survey respondents provided details on the systems and platforms used to store 3D data, how preservation packages are composed, what cost mode ls are used to finance its creation and storage, and other areas of interest, including data types, and retention methods. Readers will take away from this chapter an understanding of how the management of 3D data differs from other types, how creators can take an active role in the preservation of their 3D data, how existing managers are managing their data, and what recommendations serve as best practices in the work of preserving these assets.

description: Wir präsentieren eine abstrakte Domäne zur Ganzzahlanalyse, die für maschinennahen Code, wo Präzision besonders wichtig ist, geeignet ist. Ganzzahlanalysen approximieren Ganzzahlmengen normalerwise durch konvexe Mengen, wobei Präzision verloren geht, aber Effizienz gewonnen wird. Unsere Ganzzahlanalyse basiert auf modifizierten binären Entscheidungsbäumen (BDD), die ein effizientes Speichern von Ganzzahlmengen ermöglichen. Die zugehörigen Transferfunktionen definieren wir auf der Struktur der BDDs, was sie selbst für sehr große Mengen effizient macht. Wir stellen die Domäne in Form einer Bibliothek bereit und nutzen diese, um ein Modul für Jakstab, eine Plattform zur Binäranalyse, zu implementieren. Die Bibliothek evaluieren wir durch Vergleich mit den Mengendarstellungen traditioneller Ganzzahlanalysen, das Modul durch Anwendung auf CPU2006-Testfälle.
description: We present an abstract domain for integer value analysis that is especially suited for the analysis of low-level code, where precision is of particular interest. Traditional value analysis domains trade precision for efficiency by approximating value sets to convex shapes. Our value sets are based on modified binary decision diagrams (BDDs), which enable size-efficient storage of integer sets. The associated transfer functions are defined on the structure of the BDDs, making them efficient even for very large sets. We provide the domain in the form of a library that we use in the implementation of a plug-in for the binary analysis framework Jakstab. The library and the plug-in are evaluated by comparison to set representations in traditional value analyses and application of the plug-in to CPU2006 benchmarks respectively.

description: Cesium Bromide films grown of glass substrates by thermal evaporation showed interesting optical properties. The UV-visible absorption spectra showed peaks which showed red shift with time. Structural and morphological studies suggested decrease in grain size with time which was unusual. Theoretical simulation shows the optical behaviour to be due to surface plasmon resonance resulting from Cesium clyindrical rods embedded in the films.

Publisher: name: Zenodo

description: We introduce the concept of canary numbers, to be used in health tests for true random number generators. Health tests are essential components of true random number generators because they are used to detect defects and failures of the entropy source. These tests need to be lightweight, low-latency and highly reliable. The proposed solution uses canary numbers which are an extra output of the entropy source of lower quality. This enables an early-warning attack detection before the output of the generator is compromised. We illustrate the idea with 2 case studies of true random number generators implemented on aXilinx Spartan-6 FPGA.

description: We discuss neutrino masses from higher than d=5 effective operators in a supersymmetric framework, where we explicitly demonstrate which operators could be the leading contribution to neutrino mass in the MSSM and NMSSM. As an example, we focus on the d=7 operator L L H_u H_u H_d H_u, for which we systematically derive all tree-level decompositions. We argue that many of these lead to a linear or inverse see-saw scenario with two extra neutral fermions, where the lepton number violating term is naturally suppressed by a heavy mass scale when the extra mediators are integrated out. We choose one example, for which we discuss possible implementations of the neutrino flavor structure. In addition, we show that the heavy mediators, in this case SU(2) doublet fermions, may indeed be observable at the LHC, since they can be produced by Drell-Yan processes and lead to displaced vertices when they decay. However, the direct observation of lepton number violating processes is on the edge at LHC.

description: Mobile Commerce has staged a remarkable come-back. Driven by the technological innovations in the field of telecommunications, it is showing signs of a healthy recovery. The collapse of the dot-com boom in 2001/2002 had dealt a severe blow not only to Electronic Commerce but also to Mobile Commerce, which was just about developing at that time. In addition to a general lack of customer demand for mobile, location-based, services, it suffered heavily under the technical deficiencies of end-devices, slow data transmission and unripe technological standards. These factors in turn had a negative impact on the customer acceptance of mobile services and whatever little demand was available, was rendered useless. Many of the environmental conditions have changed since then. Technology innovations have reduced many barriers to acceptance. Increasing globalization has led to more mobility and therefore to greater demand for mobile, ubiquitios services that can be consumed “anytime, anywhere”. This paper examines different telecommunication technologies regarding their suitablilty and deficiencies. It provides an overview over the historical development of mobile technologies while pointing towards the expected future scenario.

description: Background: An asymptotic normalization coefficient (ANC) characterizes the asymptotic form of a one-nucleon overlap integral required for description of nucleon-removal reactions. Purpose: We investigate the impact of the particle continuum on proton and neutron ANCs for mirror systems from $p$- and $sd$-shell regions. Method: We use the real-energy and complex-energy continuum shell model approaches. Results: We studied the general structure of the single-particle ANCs as a function of the binding energy and orbital angular momentum. We computed ANCs in mirror nuclei for different physical situations, including capture reactions to weakly-bound and unbound states. Conclusions: We demonstrated that the single-particle ANCs exhibit generic behavior that is different for charged and neutral particles. We verified the previously proposed relation [N.K. Timofeyuk, R.C. Johnson, and A.M. Mukhamedzhanov, Phys. Rev. Lett. 91, 232501 (2003); Phys. Rev. Lett. 97, 069904(E) (2006); N. K. Timofeyuk and P. Descouvemont, Phys. Rev. C 72, 064324 (2005)] between proton and neutron mirror ANCs. We find minor modifications if the spectroscopic strength is either localized in a single state or broadly distributed. For cases when several states couple strongly to the decay channel, these modifications may reach 30%.

description: State-selected Coulomb-crystallized molecular ions were employed for the first time in ion-molecule reaction studies using the prototypical charge-transfer process $\mathrm{N_2^++N_2\rightarrow N_2+N_2^+}$ as an example. By preparing the reactant ions in a well-defined rovibrational state and localizing them in space by sympathetic cooling to millikelvin temperatures in an ion trap, state- and energy-controlled reaction experiments with sensitivities on the level of single ions were performed. The experimental results were interpreted with quasi-classical trajectory simulations on a six-dimensional potential-energy surface which provided detailed insight into translation-to-rotation energy transfer occurring during charge transfer between N$_2$ and N$_2^+$.

description: One presenter teaches Master's degree courses in Conflict Analysis & Resolution completely online, while the other presenter teaches general education astronomy online and in a hybrid-style large-enrollment laboratory class. What could these courses possibly have in common? The answer is shared approaches to assignments that work to stimulate self-motivated, deep learning in students. The teaching techniques look somewhat different in the different courses, but we will discuss three that are flexible enough to work for all kinds of classes and disciplines. Concept (or mind) maps, role playing (or expert)-type projects, and portfolios all work when we modify them to meet the delivery system and the learning goals of the course. We will provide examples of how we use these in our own courses and how we have modified them in distance and face-to-face environments. We will also give an opportunity for participants to think of ways they might apply any or all of these to their own courses.

Productive tensions : a theory of documentary theatre
Creators: name: Ferguson, Alexander
Publisher: name: University of British Columbia
Year: 2009

description: Perhaps the most basic tension in any theatrical performance is that of the actual and the fictive. There is always a doubling of performer (actor-character), time (now-then), and place (here-there) in theatrical representation. Performance theorists such as Fischer-Lichte, Boal, George, Schechner, and Turner all argue that between the poles of actual and fictive, between that which is materially present and that which is absent and referenced, lies the liminal state. The liminal state is a self-referential state that collapses binaries of here-and-there, now-and-then, and subject-and-object. This thesis examines how the idea of the document in documentary theatre complicates the basic representational tension of actual-fictive, adding other tensions that enable the liminal state (which I call the event-state) to occur. Drawing on the work of Fischer-Lichte and others, new theoretical concepts particular to the genre of documentary theatre are introduced, such as actual-documentive, embodied document, and emergency-time. Using examples from Nanay: A Testimonial Play (which I directed in Vancouver, Canada, and Berlin, Germany) I propose a theory of documentary theatre.

description: The Universe is modeled as consisting of pressureless baryonic matter and a bulk viscous fluid which is supposed to represent a unified description of the dark sector. In the homogeneous and isotropic background the \textit{total} energy density of this mixture behaves as a generalized Chaplygin gas. The perturbations of this energy density are intrinsically nonadiabatic and source relative entropy perturbations. The resulting baryonic matter power spectrum is shown to be compatible with the 2dFGRS and SDSS (DR7) data. A joint statistical analysis, using also Hubble-function and supernovae Ia data, shows that, different from other studies, there exists a maximum in the probability distribution for a negative present value of the deceleration parameter. Moreover, the unified model presented here favors a matter content that is of the order of the baryonic matter abundance suggested by big-bang nucleosynthesis. A problem of simple bulk viscous models, however, is the behavior of the gravitational potential and the reproduction of the CMB power spectrum.

description: In this letter, we propose the resonant tunneling diode (RTD) based on a double-barrier graphene/boron nitride (BN) heterostructure as device suitable to take advantage of the elaboration of atomic sheets containing different domains of BN and C phases within a hexagonal lattice. The device operation and performance are investigated by means of a self- consistent model within the non-equilibrium Green's function formalism on a tight-binding Hamiltonian. This RTD exhibits a negative differential conductance effect which involves the resonant tunneling through both the electron and hole bound states of the graphene quantum well. It is shown that the peak- to-valley ratio can reach the value of 4 at room temperature for gapless graphene and the value of 13 for a bandgap of 50 meV.

Die vorliegende Doktorarbeit setzt sich das Verstehen der wissenschaftlichen und technologischen Grundlagen des F-ICJs zum Ziel. Fügemechanismen, prozessbedingte Veränderungen in den gefügten Werkstoffen sowie das quasi-statische mechanische Verhalten von F-ICJ Verbindungen wurden untersucht, und der Einfluss der Prozessparameter auf Mikrostruktur und globale Eigenschaften der Verbindungen festgestellt. Ein „Proof of Concept“ des F-ICJ Prozesses wurde durch Optimierung anhand von Single-Spot-Proben und eine explorative Skalierungsstudie mit Multi-Spot Teilkomponenten durchgeführt.
description: Friction-based Injection Clinching Joining (F-ICJ) is a new advanced staking joining technology for lightweight hybrid structures. This PhD work was devised to understand the fundamental scientific and engineering aspects of F-ICJ. The joint formation mechanisms, process-related changes in the joined materials, and quasi-static mechanical behavior were clarified. This knowledge was used to establish relationships between processing conditions, microstructure, and global joint properties. A proof of concept of the F-ICJ process was explored by optimizing the mechanical performance in coupon level, and providing an initial assessment of scaling up to a multi-spot subcomponent.

description: Using the multiband model we analyze the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between the magnetic impurities in layered ferropnictide superconductors. In the normal state the interaction is spin isotropic and is dominated by the nesting features of the electron and hole bands separated by the antiferromagnetic momentum, ${\bf Q}_{AF}$. In the AF state the RKKY interaction maps into an effective anisotropic XXZ-type Heisenberg exchange model. The anisotropy originates from the breaking of the spin-rotational symmetry induced by the AF order and its strength depends on the size of the AF gap and the structure of the folded Fermi surface. We discuss our results in connection to the recent experiments.

description: One of the most valuable techniques college and university faculty have for facilitating active learning is the use of simulations. Simulations are exercises that replicate to a greater or lesser degree real-life scenarios in the safe environment of a classroom. Because they help students integrate practical skills in shared responses to problems, they are regularly employed in professions where quick, accurate reactions are necessary, such as medicine, aviation, and the military, but they can be useful in other disciplines, as well. Simulations promote both "deep learning" in a particular subject, so that lessons are understood more thoroughly and retained longer, and an interdisciplinary approach to issues, since typically those engaging in simulations are required to enact a variety of roles representing different areas of expertise. In this presentation, we plan to demonstrate the role of simulations in crisis communication, modeled on pedagogical techniques each of us has used in the classroom. In order to make the presentation relevant to teachers from a variety of disciplines, we will relate the planning, enactment, and outcomes of the simulation we run to other fields, as well. Participants should come prepared to play active roles in a crisis simulation.

During the session, we presented a crisis communication scenario to the participants, based on the real-life situation caused by Hurricane Isabel in the Mid-Atlantic region in 2003. First we set the stage with the scenario, explaining the great damage that the storm inflicted, using actual damage estimates from contemporary accounts. Then we broke the participants into groups representing political leaders, emergency responders, journalists, and citizens, with general guidance about how members of each group might have reacted under the stressful circumstances they found themselves in. After allowing the groups to organize themselves and discuss their options. we brought all the groups together to interact with each other, expressing their opinions about how the other groups were responding to the aftermath of Isabel. Later we debriefed the entire group to find out what strategies participants found effective and which they did not. By enacting the scenario we sought to provide "deep learning," which is the result of engaging more fully with a scenario than merely reading and talking about it.

description: Die vorliegende Studie analysiert die Technikhaltungen von Erstsemestern des Studienjahrgangs WS 2003/04 von ausgewählten technischen Studiengängen der Technischen Universität Hamburg-Harburg. Hinter der Analyse der Technikeinstellungen und -interessen steht die Annahme, dass sehr unterschiedliche StudienanfängerInnen ein technisches Studium beginnen.
 Diese Unterschiedlichkeit kann von Seiten der Hochschulen im Sinne des Diversity Management als Potenzial begriffen werden. Dieses Potenzial ist bislang jedoch noch nicht systematisch untersucht worden. Nur wenn HochschullehrerInnen umfassende Kenntnisse über ihr studentisches Klientel haben, können sie die Studierenden auch gut ausbilden. In dieser Untersuchung wurden die Technikeinstellungen und Technikinteressen von StudienanfängerInnen in den Ingenieurwissenschaften erforscht. Damit soll Aufschluss darüber gewonnen werden, mit welchen Vorkenntnissen, Erwartungen und welchen Motivationen sich
 junge Männer und Frauen in ein technisches Studium einschreiben. Mit diesen Kenntnissen wird es möglich, die Ingenieurausbildung breiter anzulegen und damit die hohen Studienabbruchquoten zu senken. Zudem könnte in den Oberstufen der Schulen konkreter für die Aufnahme eines technischen Studiums geworben werden, indem deutlich wird, dass das Lehrangebot vielseitige Einstellungs- und Interessenslagen der Studierenden aufgreift. Die Gesamtuntersuchung wurde an den technischen Fachbereichen von drei Hamburger Hochschulen durchgeführt: der Technischen Universität Hamburg-Harburg, der Universität Hamburg und der Hochschule für angewandte Wissenschaften Hamburg. An der Befragung beteiligten sich insgesamt 1188 Erstsemester. Damit konnten 50,5 % aller im WS 2003/2004
 eingeschriebenen Studienanfängerinnen und -anfänger erreicht werden. Die hier vorliegenden Ergebnisse beziehen sich auf die Teilstichprobe der Studierenden an der TUHH (N = 530).
Formation of massive globular clusters with heavy element abundance spread in the Galactic building blocks

description: A growing number of recent observations have revealed that the Galactic globular cluster (GC) omega Cen is not the only GC that shows abundance spread in heavy elements (e.g., Fe). In order to understand the origin of the Galactic GCs with heavy element abundance spread ("HEAS"), we investigate the formation processes of massive GCs (MGCs) with masses larger than 10^6 M_sun in gas-rich dwarf galaxies interacting and merging with the very young Galaxy. We find that massive and compact stellar clumps with masses larger than 10^6 M_sun, which can be regarded as progenitors of MGCs, can form from massive gas clumps that are developed through merging of gaseous regions initially at different regions and thus with different metallicities. Therefore it is inevitable that MGCs formed in dwarfs have HEAS. The abundance spread in each individual MGC depends on the radial metallicity gradient of the host dwarf such that it can be larger for the steeper metallicity gradient. For example, MGCs formed in a dwarf with a central metallicity of [Fe/H]=-1.1 and the radial gradient of -0.2 dex kpc^{-1} can have the abundance spread of Delta [Fe/H] ~.2. The simulated MGCs appear to be significantly flattened owing to their dissipative formation from gas disks of their host dwarfs. Based on these results, we discuss possibly diverse formation mechanisms for the Galactic GCs such as M22, M54, NGC 2419, omega Cen, and Terzan 5.

description: Instructors often wonder how to make their teaching more effective, in particular how to engage students with content and promote class interaction. To address this issue, teaching development (TD) groups have been established across various departments at Mason. The session presenters are the leaders of these groups. They will share their experiences facilitating TD groups and explain the nature and goals of the groups and group meetings.

Presenters will describe common topics discussed in TD groups (e.g., use of technology, flipped classrooms, formative vs. summative assessment, etc.). Participants will be asked to select a topic of interest to them and split into groups accordingly. They will then participate in an activity that will model a meeting of a TD group. Each group will be given a scenario with a description of the chosen topic (for instance, implementation of active learning in large lecture classes, active learning assessment, student resistance to active learning, etc.). During the activity, attendees will reflect on the topic and share their ideas, experience, etc.

Finally, presenters will describe the teaching inquiry (TI) groups that will be formed in fall 2015. These groups are designed for instructors who are interested in conducting pedagogical research in their courses.

title: Cell-free protein synthesis of secondary metabolite ribosomal peptides

description: Recently, there has been an increased emergence of antimicrobial resistant organisms and a decrease in antibiotic discovery, together producing a public health threat. To overcome this problem, novel antimicrobial scaffolds require development or existing structures need diversifying. Natural products are a group of diverse chemicals many of which display antimicrobial activity. The biosynthetic gene clusters encoding these products are often termed ‘cryptic’ due to not being expressed under normal laboratory conditions. Thus, making isolation of novel products difficult. Cell-free protein synthesis has recently been explored for its potential application in facilitating heterologous expression of natural product clusters as well as peptide diversification via incorporation of non-canonical amino acids. As it’s non-living, directly manipulatable nature lends itself to expression and alteration of toxic products. In this thesis we studied the potential of E. coli cell-free protein synthesis for expression of 3 putative lasso peptides, a class of natural product characterised by their lasso structure, isolated from Streptomyces genomes. The natural product clusters were amplified from their respective genomes using an optimized PCR protocol for the amplification of high GC sequences and cloned into plasmids for expression in cell-free systems. However, further experiments are required to allow for their expression. Moreover, steps were taken towards producing a E. coli cell-free system for incorporation of tryptophan analogues into peptides with a direct read out of successful incorporation. A deCFP marker was produced to allow for identification of ncAA incorporation, however supporting mutations within its sequence are required to increase quantum yields to suitable levels. Furthermore, amino acid depletion steps are required during cell-free lysate production to allow for efficient incorporation of ncAAs. Finally, bioinformatic investigation of RiPP biosynthetic gene cluster intergenic regions was carried out to probe for the presence of intrinsic terminators involved in their regulation. This identified secondary structures present within the intergenic regions of all RiPP clusters tested, par one. Furthermore, MSA of intergenic regions of clusters homologous to the 3 clusters of interest suggested that these secondary structures may be conserved across lasso peptides.
