The ITER electron cyclotron (EC) system with its four upper launchers (UL) and one equatorial launcher (EL) will be used for central heating and current drive as well as for the control of magneto-hydrodynamic instabilities of the plasma. The diamond windows are part of the EC transmission line system, allow the transmission of high mm-wave power (at 170 GHz) from the gyrotrons to the launchers and serve as vacuum and tritium barriers to the ITER vacuum vessel. A polycrystalline diamond disk produced by MPA-CVD (microwave plasma assisted chemical vapour deposition) process is the functional element of such a torus window and acts as part of the first confinement barrier (SIC-1). Diamond is selected as window material because of its high mechanical stability, high thermal conductivity and very low dielectric loss. The latter guarantees a minimal absorption of the mm-wave power and results in moderate temperatures and consequent low thermal stresses.
The determination of the losses and the verification of the required low value is therefore essential for the qualification of diamond disks for high-power windows. Dedicated measuring set-ups (Fabry-Perot resonators) at Karlsruhe Institute of Technology (KIT) enable high resolution measurements of the loss tangent at the disk centre (spherical set-up) as well as a mapping over the disk area to estimate its homogeneity (hemispherical set-up). The disk characterization is then completed by an inspection with a digital microscope.
Prior to their integration to the window assemblies, more than 60 diamond disks (D=70mm, t=1.11mm) need to be qualified with respect to the requirements. The work is performed within a contract between F4E and KIT. A dedicated test plan has been provided and the first batches of disks produced by Diamond Material GmbH have been delivered to KIT. First results of loss tangent measurements and microscopy investigations will be presented.

description: We propose to create superposition states of over 100 Strontium atoms being in a ground state or metastable optical clock state, using the Kerr-type interaction due to Rydberg state dressing in an optical lattice. The two components of the superposition can differ by of order 300 eV in energy, allowing tests of energy decoherence models with greatly improved sensitivity. We take into account the effects of higher-order nonlinearities, spatial inhomogeneity of the interaction, decay from the Rydberg state, collective many-body decoherence, atomic motion, molecular formation and diminishing Rydberg level separation for increasing principal number.

description: Neutrinos are the only particles in the Standard Model of particle physics that have only been observed with left handed chirality to date. If right handed neutrinos exist, they would not only explain the observed neutrino oscillations, but could also be responsible for several phenomena in cosmology, including the baryon asymmetry of the universe, dark matter and dark radiation. A crucial parameter in this context is their Majorana mass, which in principle could lie anywhere between the eV scale and GUT scale. The implications for experiments and cosmology strongly depend on the choice of the mass scale. We review recent progress in the phenomenology of right handed neutrinos with different masses, focusing on scenarios in which the mass is at least a keV. We emphasise the possibility to discover heavy neutrinos that are responsible for the baryon asymmetry of the universe via low scale leptogenesis in near future experiments, such as LHC, BELLE II, SHiP, FCC-ee or CEPC.

Secure, Contain, Protect: Building a Digital Folklore Mythos through Collaborative Legend Creation

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: The SCP Wiki is a collaborative creative writing website specializing in the bizarre and horrific. Within a fictional world, supernatural creatures threaten humanity’s survival. The Foundation, a shadowy organization, aims to secure and contain these entities and protect the human race from extinction. Each SCP article delineates in scientific tone the containment procedures of a particular entity.
There are four distinctive elements of the SCP Wiki. First, the community, with its large user base and amount of content, can only exist online because of the accessibility of information and collaboration.
Second, the writers’ artistic style intentionally mirrors the visual aesthetics of declassified government documents in order to lend realism to their own fictional works.
Third, the SCP Wiki community has collaboratively constructed an elaborate legend complex about the fictional Foundation, which they then engage with through writing and community participation. This demonstrates that, although it does not have to, reverse ostension, engagement with a self-made legend, can occur in a purely digital community.
Last, the community’s group formation and reverse ostensive practices are mutually co-constructing. Group members are drawn to the SCP Wiki because of their interest in the content, but the content only exists because group members collaboratively construct it.
This thesis explores the unique group formation and folklore processes used by the SCP Wiki community. Despite its geographically distant users, the Wiki’s community continues to grow. The SCP Wiki and its fiction work with the Foundation demonstrates how online communities engage with legend creation and ostension, and elucidates how reverse ostension and group formation interact.

description: We study the moduli space of handlebodies diffeomorphic to $(D^{n+1}\times S^{n})^{\natural g}$, i.e. the classifying space $BDiff((D^{n+1}\times S^n)^{\natural g}, D^{2n})$ of the group of diffeomorphisms that restrict to the identity near a $2n$-dimensional disk embedded in the boundary, $\partial(D^{n+1}\times S^n)^{\natural g}$. We construct a map $colim_{g\to\infty}BDiff((D^{n+1}\times S^n)^{\natural g}, D^{2n}) \longrightarrow Q_{0}BO(2n+1)\langle n \rangle_{+}$ and prove that it induces an isomorphism on integral homology in the case that $2n+1 \geq 9$. Above, $BO(2n+1)\langle n \rangle$ denotes the $n$-connective cover of $BO(2n+1)$. The (co)homology of the space $Q_{0}BO(2n+1)\langle n \rangle_{+}$ is well understood and so our results enable one to compute the homology groups $H_{k}(BDiff((D^{n+1}\times S^n)^{\natural g}, D^{2n}))$ in a range of degrees when $k << g$. Our main theorem can be viewed as an analogue of the Madsen-Weiss theorem for the moduli spaces of surfaces and the recent theorem of Galatius and Randal-Williams for the moduli spaces of manifolds of dimension $2n \geq 6$.

description: We study the ultraviolet properties of theories whose fundamental fields display a confining, Gribov-type, propagator. These are propagators that exhibit complex poles and violate positivity, thus precluding a physical propagating particle interpretation. We show that the properties of this type of confining propagators do not change the ultraviolet behavior of the theory, in the sense that no new ultraviolet primitive divergences are generated, thus securing the renormalizability of these confining theories. We illustrate these properties by studying a variety of models, including bosonic and fermionic confined degrees of freedom. The more intricate case of Super Yang-Mills with ${\cal N} =1$ supersymmetries in the Wess-Zumino gauge is taken as example in order to prove these statements to all orders by means of the algebraic renormalization set up.

A Heuristic Approach to the Quantum Measurement Problem: How to Distinguish Particle Detectors from Ordinary Objects
Creators: name: Merlin, R.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Elementary particle detectors fall broadly into only two classes: phase-transformation devices, such as the bubble chamber, and charge-transfer devices like the Geiger-Mueller tube. Quantum measurements are seen to involve transitions from a long-lived metastable state (e. g., superheated liquid or a gas of atoms between charged capacitor plates) to a thermodinamically stable condition. A detector is then a specially prepared object undergoing a metastable-to-stable transformation that is significantly enhanced by the presence of the measured particle, which behaves, in some sense, as the seed of a process of heterogeneous nucleation. Based on this understanding of the operation of a conventional detector, and using results of orthogonality-catastrophe theory, we argue that, in the thermodynamic limit, the pre-measurement Hamiltonian is not the same as that describing the detector during or after the interaction with a particle and, thus, that superpositions of pointer states (Schroedinger cats) are unphysical because their time evolution is ill defined. Examples of particle-induced changes in the Hamiltonian are also given for ordinary systems whose macroscopic parameters are susceptible to radiation damage, but are not modified by the interaction with a single particle.

Diagnosing Alarm Fatigue in a Children's Hospital
Creators: name: Fry, Christopher
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Background: Alarm safety is one of the most prominent and high profile problems in
hospitals. When alarms sound constantly throughout the day nurses may experience sensory
overload. This desensitizes nurses to alarms, which can create an unsafe, and in some events even fatal environment for the patients. Methods: Central monitoring data was collected on 4 units throughout the Children’s Hospital. Researchers observed central monitor and nurses’ verbal and nonverbal reactions to those alarms. Nurses were also preliminarily surveyed to address their perceptions of alarms on the unit. Results: The average number of alarms per bed, 35 an hour, was extremely high. Nurses also stated in the survey they were desensitized to alarms and the majority believed their coworkers did not handle alarms appropriately. Observations of the nurses revealed that only 22% of nurse responses to alarms were positive. Conclusion: The results of this study indicate that alarm fatigue is present in the hospital setting. By identifying
the nurses’ response to the alarms (verbal and non-verbal) as well as the frequency of alarms on the unit, a better understanding of alarm fatigue was achieved. The results of this study indicate a great need for interventions developed to address alarm frequency and the nurses’ responses to alarms.

description: The Sloan Digital Sky Survey IV extended Baryonic Oscillation Spectroscopic Survey (SDSS-IV/eBOSS) will observe 195,000 emission-line galaxies (ELGs) to measure the Baryonic Acoustic Oscillation standard ruler (BAO) at redshift 0.9. To test different ELG selection algorithms, 9,000 spectra were observed with the SDSS spectrograph as a pilot survey based on data from several imaging surveys. First, using visual inspection and redshift quality flags, we show that the automated spectroscopic redshifts assigned by the pipeline meet the quality requirements for a reliable BAO measurement. We also show the correlations between sky emission, signal-to-noise ratio in the emission lines, and redshift error. Then we provide a detailed description of each target selection algorithm we tested and compare them with the requirements of the eBOSS experiment. As a result, we provide reliable redshift distributions for the different target selection schemes we tested. Finally, we determine an target selection algorithms that is best suited to be applied on DECam photometry because they fulfill the eBOSS survey efficiency requirements.

description: Massive MIMO is a new technique for wireless communications that claims to offer very high system throughput and energy efficiency in multi-user scenarios. The cost is to add a very large number of antennas at the base station. Theoretical research has probed these benefits, but very few measurements have showed the potential of Massive MIMO in practice. We investigate the properties of measured Massive MIMO channels in a large indoor venue. We describe a measurement campaign using 3 arrays having different shape and aperture, with 64 antennas and 8 users with 2 antennas each. We focus on the impact of the array aperture which is the main limiting factor in the degrees of freedom available in the multiple antenna channel. We find that performance is improved as the aperture increases, with an impact mostly visible in crowded scenarios where the users are closely spaced. We also test MIMO capability within a same user device with user proximity effect. We see a good channel resolvability with confirmation of the strong effect of the user hand grip. At last, we highlight that propagation conditions where line-of-sight is dominant can be favorable.

description: We briefly review the growing efforts to set up a unified framework for the description of neutrino interactions with atomic nuclei and nuclear matter, applicable in the broad kinematical region corresponding to neutrino energies ranging between few MeV and few GeV. The emerging picture suggests that the formalism of nuclear many-body theory can be exploited to obtain the neutrino-nucleus cross sections needed for both the interpretation of oscillation signals and simulation of neutrino transport in compact stars.

Susan Hill At the Supreme Court: Reproductive Rights Advocacy in the Deep South Remembered

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This thesis is an examination of the monumental strength of abortion clinic owners in the post-Roe v. Wade era. In particular, I have chosen to focus on the life and work of Susan Hill, a native of Durham, N.C., and lifelong advocate for reproductive freedom. In 1986, Hill was approached by Ellie Smeal of the National Organization for Women to join a burgeoning lawsuit against the growing intrusion of anti-choice protestors at clinics nationwide. Hill signed on as a key plaintiff and witness for the case, which would ultimately find itself before the Supreme Court. The case, filed as NOW vs. Scheidler, argued under the RICO (Racketeer-Influenced Corrupt Organizations) Act with Hill as a key plaintiff, marked a sharp departure from previously legal strategies employed by reproductive rights organizations. I argue Hill’s inclusion as a plaintiff determined the course of the case overall: her insight as a clinic owner drove the argument from which NOW successfully charged Joseph Scheidler and associates with racketeering in 1998.
In examining my thesis topic against major historiographical fields, I found two to be most relevant to my subject: feminist historiography (an admittedly vast and multifaceted heading) and legal historiography—specifically as it relates to the study of precedent in the United States justice system.

description: We study the vertical structure of a stellar disk obtained from a fully cosmological high-resolution hydrodynamical simulation of the formation of a Milky Way-like galaxy. At the present day, the disk's mean vertical height shows a well-defined and strong pattern, with amplitudes as large as 3 kpc in its outer regions. This pattern is the result of a satellite - host halo - disk interaction and reproduces, qualitatively, many of the observable properties of the Monoceros Ring. In particular we find disk material at the distance of Monoceros ($R \sim$ 12-16 kpc, galactocentric) extending far above the mid plane ( 30$^{\circ}$, $\langle Z \rangle \sim$ 1-2 kpc) in both hemispheres, as well as well-defined arcs of disk material at heliocentric distances $\gtrsim 5$ kpc. The pattern was first excited $\approx 3$ Gyr ago as an $m=1$ mode that later winds up into a leading spiral pattern. Interestingly, the main driver behind this perturbation is a low-mass low-velocity fly-by encounter. The satellite has total mass, pericentre distance and pericentric velocity of $\sim 5\%$ of the host, $\sim 80$ kpc, and 215 km/s, respectively. The satellite is not massive enough to directly perturb the galactic disk but we show that the density field of the host dark matter halo responds to this interaction resulting in a strong amplification of the perturbative effects. This subsequently causes the onset and development of the Monoceros-like feature.

description: In building up composite structures using carbon nanotube (CNT) fibers, the fiber-to-matrix interfacial shear strength (IFSS) is one of the most important issues. Originating from the assembly characteristics of CNT fiber, the IFSS strongly depends on the fiber's twisting level and densification level. Furthermore, there are rich ways to modify the fiber surface and thus enhance the IFSS, including the physical and chemical modification on fiber surface, the infiltration of matrix resin into CNT fiber, and the introduction of silane coupling agent. A new feature differing from carbon fibers is that all these treatments either change the fiber's surface structure or form a several-hundreds-nm-thick interphase inside rather than around the fiber. These "generalized" treatments obviously extend the common concept of surface sizing and can be used for various forms of CNT assembly structures.

Portraits exhibiting her ghostly pale visage and flaming red hair, coupled with the larger than life
gowns dripping in jewels, have become iconic images of the so-called Golden Age of the English
Renaissance. Her image, as enduring as it is today, was the foundation upon which Elizabeth
built her royal power, each and every move carefully calculated to mold her into the living
legend that she was during her reign. Upon coming to power at the age of twenty-five, Elizabeth
I ascended the throne of a kingdom riddled with debt, and torn apart by religious factionalism
and turmoil. Over the course of her forty-four year reign, she shaped England into a global
power, bringing about an economic prosperity not enjoyed since the reign of Elizabeth’s
grandfather, Henry VII. The calming of social and religious tensions, coupled with economic
stability, allowed the arts to flourish during the Elizabethan Age. Perhaps best known as ‘the
Virgin Queen’, the Elizabeth I recognized by history is a product of the combined resources of
the various art media available during the Early Modern period. The image of Queen Elizabeth I
was carefully and meticulously crafted to present an authoritative and strong feminine figure in a
world dominated by men. Literature, portraits, plays, speeches, and prayers alike fashioned
Elizabeth Tudor into a Goddess on earth, most frequently the virginal Diana, the Greco-Roman
goddess of the moon and the hunt. Through the myriad artistic forms employed to represent and
emulate Queen Elizabeth I, a profile of the multifaceted woman behind the legend can be
assembled, each exposing a different facet of the Queen, and each being another example of a
manufactured image or persona of the monarch.

description: We study the polarization optical properties of microcavities with embedded (110)-oriented quantum wells. The spin dynamics of exciton polaritons in such structures is governed by the interplay of the spin-orbit splitting of exciton states, which is odd in the in-plane momentum, and the longitudinal-transverse splitting of cavity modes, which is even in the momentum. We demonstrate the generation of polariton spin currents by linearly polarized optical pump and analyze the arising polariton spin textures in the cavity plane. Tuning the excitation spot size, which controls the polariton distribution in the momentum space, one obtains symmetric or asymmetric spin textures.

description: Starting from a microscopic model for a spherically symmetric active Janus particle, we study the interactions between two such active motors. The ambient fluid mediates a long range hydrodynamic interaction between two motors. This interaction has both direct and indirect hydrodynamic contributions. The direct contribution is due to the propagation of fluid flow that originated from a moving motor and affects the motion of the other motor. The indirect contribution emerges from the re-distribution of the ionic concentrations in the presence of both motors. Electric force exerted on the fluid from this ionic solution enhances the flow pattern and subsequently changes the motion of both motors. By formulating a perturbation method for very far separated motors, we derive analytic results for the transnational and rotational dynamics of the motors. We show that the overall interaction at the leading order, modifies the translational and rotational speeds of motors which scale as ${\cal O}\left([1/D]^3\right)$ and ${\cal O}\left([1/D]^4\right)$ with their separation, respectively. Our findings open up the way for studying the collective dynamics of synthetic micro motors.

description: Ob "Women and girls", "persons with disabilities" oder "people of African descent" - die Kampagnen, Erklärungen und Programme internationaler Organisationen rücken unterschiedliche Personenkategorien ins Zentrum politischer Aufmerksamkeit und reproduzieren eine globale Beobachtungsordnung, die die Welt primär als personal differenziert begreift. "Globale Personenkategorien" - so die Kernannahme des Beitrages - sind dabei nicht reine Abbildungen sozialer Wirklichkeit, sondern kontingente Konstruktionen, die auf der Unterscheidung von Ähnlichem und Unähnlichem beruhen. Vor diesem Hintergrund identifiziert der Beitrag einige Charakteristika globaler Kategorienbildung. Er geht insbesondere auf die Besonderheiten der Etablierung globaler kategorialer Räume ein, die nationale, regionale und kulturelle Partikularitäten überlagern, und fragt nach dem konfliktreichen Verhältnis zwischen der Herstellung kategorialer Einheit und der Beobachtung von Differenz.

description: Twitch-Clips können als kompakte Vertreter des audiovisuellen Livestreaming-Formats verstanden werden, das sich aktuell - besonders auch durch pandemiebedingte Digitalisierungsschübe - auf dem Weg in den Mainstream befindet. Eigenschaften wie interaktive und produktive Ko-Orientierung, Authentizität, visuelle Publikums-Repräsentation und Open-Endedness gewinnen zunehmend Einzug in die Medienwelt. Sowohl für den Medien- als auch beim Publikumswandel repräsentieren Twitch-Clips einen signifikanten Entwicklungsschritt in Richtung interaktiver Rezeption und Publikumsrepräsentation, da Zuschauer*Innen erstmals in Echtzeit an der Entstehung von Medieninhalten kollektiv mitwirken und sich dabei Grenzen zwischen Medienpersönlichkeiten und ihren Publika auflösen. Clip-Kulturen lassen sich in diesem Kontext ganz wörtlich verstehen, da Clips selbst zu Live-on-Tape Aufnahmen von konkreten, in Videoformat verewigten sozialen Interaktionen werden. Audiovisuelle Medien entwickeln sich zu Trägern von öffentlichem, interaktionalem Gehalt und damit zu eigenen Kommunikationsarenen, die stets alle Teilnehmer*Innen und deren Bezugsobjekte visuell repräsentieren. In diesem Zusammenhang stehen sowohl die Filmsoziologie als auch die Medien- und Kommunikationssoziologie auch zukünftig vor der Aufgabe intensiver Zusammenarbeit, da durch den Wandel audiovisueller Online-Medien auch deren Forschungsgebiete zunehmend miteinander verschmelzen.

Visualizing Carrier Dynamics in Transition Metal Dichalcogenide Nanoflakes using Femtosecond Pump-Probe Microscopy
Creators: name: Armstrong, Emilee

description: Transition metal dichalcogenides are a semiconducting material that are of interest in the scientific community for their applications in photovoltaics, flexible electronics, and medicine. It is important to understand how the structural features of these materials impact the carrier dynamics, such as exciton recombination and free carrier relaxation, so that their behavior in electronic applications can be better understood. Within this experiment, two transition metal dichalcogenides, molybdenum disulfide (MoS2) and tungsten disulfide (WS2) were investigated using femtosecond pump-probe microscopy. Pump-probe microscopy enables the measurement of dynamics that occur on fast time scales in precise regions. In the WS2 study, it was found that excitons recombine at a faster rate at the edge of the flake in comparison to the center. The impact of nanoflake thickness on carrier dynamics in MoS2 was also explored, and it was found that thinner flakes facilitate a faster exciton recombination.  Understanding how thickness and excitation location impact carrier dynamics is essential for being able to compare different transition metal dichalcogenide materials and understanding their potential applications.
Mean-square convergence of the BDF2-Maruyama and backward Euler schemes for SDE satisfying a global monotonicity condition

description: In this paper the numerical approximation of stochastic differential equations satisfying a global monotonicity condition is studied. The strong rate of convergence with respect to the mean square norm is determined to be $\frac{1}{2}$ for the two-step BDF-Maruyama scheme and for the backward Euler-Maruyama method. In particular, this is the first paper which proves a strong convergence rate for a multi-step method applied to equations with possibly superlinearly growing drift and diffusion coefficient functions. We also present numerical experiments for the $\tfrac32$-volatility model from finance, which verify our results in practice and indicate that the BDF2-Maruyama method offers advantages over Euler-type methods if the stochastic differential equation is stiff or driven by a noise with small intensity.

description: In a topological crystalline insulator (TCI) the inversion of the bulk valence and conduction bands is a necessary condition to observe surface metallic states. Solid solutions of Pb$_{1-x}$Sn$_x$Te have been shown to be TCI, where band inversion occurs as a result of the band gap evolution upon alloying with Sn. The origins of this band inversion remain unclear. Herein the role of Sn insertion into the PbTe matrix is investigated for the $p$-type Pb$_{1-x}$Sn$_x$Te series with $x$ = 0, 0.35, 0.60, and 1.00 via nuclear magnetic resonance (NMR) and transport measurements. $^{207}$Pb, $^{119}$Sn, and $^{125}$Te line shapes, spin-lattice relaxation rates, and Knight shifts provide site-specific characterization of the electronic band structure. This probe of the electronic band structure shows that the band inversion is unaffected by lattice distortions but related to spatial electronic inhomogeneities formed by Sn incorporation into the PbTe matrix. Strong relativistic effects are found to be responsible for the band inversion, regardless of carrier type and concentration, suggesting a novel interpretation of the band gap evolution with composition. The temperature dependences of the NMR parameters reveal a negative temperature coefficient of the direct gap for SnTe and positive coefficient for PbTe.

description: White dwarfs are the fossils left by the evolution of low-and intermediate-mass stars, and have very long evolutionary timescales. This allows us to use them to explore the properties of old populations, like the Galactic halo. We present a population synthesis study of the luminosity function of halo white dwarfs, aimed at investigating which information can be derived from the currently available observed data. We employ an up-to-date population synthesis code based on Monte Carlo techniques, that incorporates the most recent and reliable cooling sequences for metal poor progenitors as well as an accurate modeling of the observational biases. We find that because the observed sample of halo white dwarfs is restricted to the brightest stars only the hot branch of the white dwarf luminosity function can be used for such purposes, and that its shape function is almost insensitive to the most relevant inputs, like the adopted cooling sequences, the initial mass function, the density profile of the stellar spheroid, or the adopted fraction of unresolved binaries. Moreover, since the cut-off of the observed luminosity has not been yet determined only lower limits to the age of the halo population can be placed. We conclude that the current observed sample of the halo white dwarf population is still too small to obtain definite conclusions about the properties of the stellar halo, and the recently computed white dwarf cooling sequences which incorporate residual hydrogen burning should be assessed using metal-poor globular clusters.
