Nightlight: Tradition and Change in a Local Music Scene
Creators: name: Smithers, Aaron Nathaniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This thesis considers how tradition—as a dynamic process—is crucial to the development, maintenance, and dissolution of the complex networks of relations that make up local music communities.  Using the concept of “scene” as a frame, this ethnographic project engages with participants in a contemporary music scene shaped by a tradition of experimentation that embraces discontinuity and celebrates change.  This tradition is learned and communicated through performance and social interaction between participants connected through the Nightlight—a music venue in Chapel Hill, North Carolina.
Check Belief Propagation Decoding of LDPC Codes

description: Variant belief propagation (BP) algorithms are applied to low-density parity-check (LDPC) codes. However, conventional decoders suffer from a large resource consumption due to gathering messages from all the neighbour variable-nodes and/or check-nodes through cumulative calculations. In this paper, a check-belief propagation (CBP) decoding algorithm is proposed. Check-belief is used as the probability that the corresponding parity-check is satisfied. All check-beliefs are iteratively enlarged in a sequential recursive order, and successful decoding will be achieved after the check-beliefs are all big enough. Compared to previous algorithms employing a large number of cumulative calculations to gather all the neighbor messages, CBP decoding can renew each check-belief by propagating it from one check-node to another through only one variable-node, resulting in a low complexity decoding with no cumulative calculations. The simulation results and analyses show that the CBP algorithm provides little error-rate performance loss in contrast with the previous BP algorithms, but consumes much fewer calculations and memories than them. It earns a big benefit in terms of complexity.

description: A practical scheme for the demonstration of perfect one-sided device-independent quantum secret sharing is proposed. The scheme involves a three-mode optomechanical system in which a pair of independent cavity modes is driven by short laser pulses and interact with a movable mirror. We demonstrate that by tuning the laser frequency to the blue (anti-Stokes) sideband of the average frequency of the cavity modes, the modes become mutually coherent and then may collectively steer the mirror mode to a perfect Einstein-Podolsky-Rosen state. The scheme is shown to be experimentally feasible, it is robust against the frequency difference between the modes, mechanical thermal noise and damping, and coupling strengths of the cavity modes to the mirror.

description: Generalized avoidance behaviors are a common diagnostic feature of anxiety-related disorders and a barrier to affecting changes in anxiety during therapy. However, strategies to mitigate generalized avoidance are under-investigated. Even less attention is given to reducing the category-based generalization of avoidance. We therefore investigated the potential of an operant-based approach. Specifically, it was examined if reinforcing competing (non-avoidance) behaviors to threat-predictive cues would interfere with expression of generalized avoidance. Using a matching-to-sample task, artificial stimulus categories were established using physically dissimilar nonsense shapes. A member of one category (conditioned stimulus; CS1) was then associated with an aversive outcome in an Acquisition context, unless an avoidance response was made. Next, competing behaviors were reinforced in response to the CS1 in new contexts. Lastly, we tested for the generalization of avoidance to another member of the stimulus category (generalization stimulus; GS1) in both a Novel context and the Acquisition context. The selective generalization of avoidance to GS1 was observed, but only in the Acquisition context. In the Novel context, the generalization of avoidance to GSs was significantly reduced. A comparison group (Experiment 2), which did not learn any competing behaviors, avoided GS1 in both contexts. These findings suggest that reinforcing competing behavioral responses to threat-predictive cues can lead to reductions in generalized avoidance. This study is among the first study to demonstrate sustained reductions in generalized avoidance resulting from operant-based protocols, and the clinical and research implications are discussed.

description: Pronouns have an indexical or deictic function. Their reference is variable, in the case of personal pronouns depending on pragmatic factors such as who is speaking to whom and who is being talked about, and it can be adjusted quite flexibly to textual and contextual, or conversational needs. So, while their anaphoric qualities make them an important instrument for creating textual cohesion, which under normal circumstances (i.e., on unmarked levels of interpretation) is a prerequisite for contextual coherence, their referential variability can result in vagueness and fluctuating uncertainty. What is locally cohesive can thus still be contextually incoherent. Proper names, on the other hand, are normally used as rigid designators. Quoted forms can be viewed as a specific class of (proper) names individualizing particular forms as relocations of their category (I cannot go into more detail here about the different kinds of nominalizations and their effects); quotation can thus be regarded as a means of transforming variable designators into rigid ones. In the enigmatic poem to be discussed, Lewis Carroll makes ample use of this instrument; as the English past tense doesn't have person or number agreement (cf. I/You/He/She/It went), he can easily avoid explicitly noting the difference between quoted and unquoted (anaphoric) forms, and can rather draw specifically on the resulting ambiguity. His virtuosity in handling the different levels of designation illustrates how human symbolic abilities allow him (and us) to introduce new levels of meaning and to stimulate our search for possible interpretations by obscuring the seemingly obvious.

description: We present a complete algebraic classification for the curvature tensor in Weyl-Cartan geometry, by applying methods of eigenvalues and principal null directions on its irreducible decomposition under the group of global Lorentz transformations, thus providing a full invariant characterisation of all the possible algebraic types of the torsion and nonmetricity field strength tensors in Weyl-Cartan space-times. As an application, we show that in the framework of Metric-Affine Gravity the field strength tensors of a dynamical torsion field cannot be doubly aligned with the principal null directions of the Riemannian Weyl tensor in scalar-flat, slowly rotating, stationary and axisymmetric space-times.

description: Mit den Pluemen der Tugent und Des Teufels Netz hat Franz Josef Schweitzer zwei Lehrgedichte in das Zentrum seiner Habilitationsschrift gestellt, wie sie im späten Mittelalter gern gehört und gelesen wurden. Die Pluemen sind eine Übersetzung des Südtiroler Adligen Hans Vintler, der das Erfolgsbuch des mutmaßlichen Dominikaners Tommaso Gozzadini aus Bologna, die Fiori di virtuy die schon eine Vielzahl von Übersetzungen in mehrere Sprachen erfahren hatten, gut ein Jahrhundert nach ihrer Abfassung, 1411, ins Deutsche übertragen hat. Die beiden anonymen unterschiedlichen Fassungen von Des Teufels Netz werden gleichfalls in die erste Hälfte des 15. Jahrhunderts datiert. Ziel der Untersuchung, so Schweitzer, ist es, den beiden Gedichten „möglichst konkrete Erkenntnisse über Wertbegriffe und Wertvorstellungen" (S.1) des 15. Jahrhunderts abzugewinnen.

description: Multiferroic tunnel junctions (MFTJs) based on two-dimensional (2D) van der Waals heterostructures with sharp and clean interfaces at the atomic scale are crucial for applications in nanoscale multi-resistive logic memory devices. The recently discovered sliding ferroelectricity in 2D van der Waals materials has opened new avenues for ferroelectric-based devices. Here, we theoretically investigate the spin-dependent electronic transport properties of Fe$_3$GeTe$_2$/graphene/bilayer-$h$-BN/graphene/CrI$_3$ (FGT/Gr-BBN-Gr/CrI) all-vdW MFTJs by employing the nonequilibrium Green's function combined with density functional theory. We demonstrate that such FGT/Gr-BBN-Gr/CrI MFTJs exhibit four non-volatile resistance states associated with different staking orders of sliding ferroelectric BBN and magnetization alignment of ferromagnetic free layer CrI$_3$, with a maximum tunnel magnetoresistance (electroresistance) ratio, i.e., TMR (TER) up to $\sim$$3.36\times10^{4}$\% ($\sim$$6.68\times10^{3}$\%) at a specific bias voltage. Furthermore, the perfect spin filtering and remarkable negative differential resistance effects are evident in our MFTJs. We further discover that the TMR, TER, and spin polarization ratio under an equilibrium state can be enhanced by the application of in-plane biaxial strain. This work shows that the giant tunneling resistance ratio, multiple resistance states, and excellent spin-polarized transport properties of sliding ferroelectric BBN-based MFTJs indicate its significant potential in nonvolatile memories.

The Impact of Dimensions of Experience on Behavior: Examining the Role of Deprivation and Threat in Early Childhood
Creators: name: Machlin, Laura
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Deprivation, defined as the absence of expected cognitive and social inputs, is associated with worse executive functioning. Threatening experiences, defined as the presence of atypical traumatic learning experiences, are associated with impaired fear learning processes. No prior work has examined the effects of deprivation and threat together outside of adolescence. The present study examines how deprivation and threat are associated with behavior in children 4-7 years old. Children (N = 63) completed executive functioning and fear conditioning tasks. To operationalize deprivation and threat, an index score was created from each relevant measure from child and parent report. Deprivation was associated with worse cognitive control. Threat was associated with greater attentional bias towards threat-related cues and greater generalization of physiological response during fear extinction. All analyses controlled for age, gender, IQ, and other experiences (deprivation or threat). Future work should examine neural mechanisms underlying behavioral changes associated with early adversity.

description: Anomalous Microwave Emission (AME) is an important emission component between 10 and 60 GHz that is not yet fully understood. It seems to be ubiquituous in our Galaxy and is observed at a broad range of angular scales. Here we use the new QUIJOTE-MFI wide survey data at 11, 13, 17 and 19 GHz to constrain the AME in the Galactic plane ($|b|<10^\circ$) on degree scales. We built the spectral energy distribution between 0.408 and 3000 GHz for each of the 5309 0.9$^\circ$ pixels in the Galactic plane, and fitted a parametric model by considering five emission components: synchrotron, free-free, AME, thermal dust and CMB anisotropies. We show that not including QUIJOTE-MFI data points leads to the underestimation (up to 50 %) of the AME signal in favour of free-free emission. The parameters describing these components are then intercompared, looking for relations that help to understand AME physical processes. We find median values for the AME width, $W_{\rm AME}$, and for its peak frequency, $ν_{\rm AME}$, respectively of $0.560^{+0.059}_{-0.050}$ and $20.7^{+2.0}_{-1.9}$ GHz, slightly in tension with current theoretical models. We find spatial variations throughout the Galactic plane for $ν_{\rm AME}$, but only with reduced statistical significance. We report correlations of AME parameters with certain ISM properties, such as that between the AME emissivity (which shows variations with the Galactic longitude) and the interstellar radiation field, and that between the AME peak frequency and dust temperature. Finally, we discuss the implications of our results on the possible molecules responsible for AME.

Technology Social Ventures: A managerial perspective across sectors in Europe
Creators: name: Meggio, Gianlorenzo
Publisher: name: Zenodo
Year: 2022

description: We know a lot about social ventures and high-tech firms, but in a world awash with crises and where governments are pressured to reduce their spending, the practice of applying advanced technologies to find more efficient market solutions that can tackle societal issues is still in its infancy. This study explores the case of Technology Social Ventures (TSVs) to understand how the simultaneous integration of a social mission and a tech-based strategy impact their business. Moreover, the article investigates how this combination affects TSVs in comparison with traditional Social Ventures (SVs) and New Technology-Based Firms (NTBFs), where the social and technological aspects are not integrated.
 The empirical work is based on a qualitative study, where a sample of 15 TSVs operating in different sectors across Europe is investigated. The findings show how all TSVs share some invariant elements, complemented by dynamic factors that differentiate their needs and activities, depending on their main driver, belonging sector and technology adopted. Overall, the article argues that the adoption of a social mission by a NTBF generates more complexity with respect to the benefits brought by the integration of technology within SVs.
 These findings contribute to the literature at the intersection between social and high-tech entrepreneurship, calling for further research that could inform policy-makers on the specific needs of these firms, at each stage of their development. Finally, investors and managers might benefit from this study, as they can identify more easily the opportunities and challenges of leading a tech-based venture with a social mission.
Hanbury Brown-Twiss Effect with Wave Packets

description: The Hanbury Brown-Twiss (HBT) effect, at the quantum level, is essentially an interference of one particle with another, as opposed to interference of a particle with itself. Conventional treatments of identical particles encounter difficulties while dealing with entanglement. A recently introduced label-free approach to indistinguishable particles is described, and is used to analyze the HBT effect. Quantum wave-packets have been used to provide a better understanding of the quantum interpretation of the HBT effect. The effect is demonstrated for two independent particles governed by Bose-Einstein or Fermi-Dirac statistics. The HBT effect is also analyzed for pairs of entangled particles. Surprisingly, entanglement has almost no effect on the interference seen in the HBT effect. In the light of the results, an old quantum optics experiment is reanalyzed, and it is argued that the interference seen in that experiment is not a consequence of non-local correlations between the photons, as is commonly believed.

description: A prototype Dual Gain Multilayer Thick Gas Electron Multilyer (DG-M-THGEM) with an active area of 10 cm $\times$ 10 cm was manufactured aiming at the production of a large-volume active-target time projection chamber which can work under the condition of high-intensity heavy-ion beam injections. The DG-M-THGEM has a alternating structure of electrodes and insulators. Effective gas gains of two regions, which are called beam and recoil regions, are separately controlled. Performance of the prototype DG-M-THGEM in hydrogen gas at a pressure of 40 kPa was evaluated. Irradiating a $^{132}$Xe beam, an effective gas gain lower than 100 with a charge resolution of 3% was achieved in the beam region while the effective gas gain of 2000 was maintained in the recoil region. Position distributions of measured charges along the beam axis were investigated in order to evaluate gain uniformity in the high intensity beam injection. The gain shift was estimated by simulations considering space charges in the drift region. The gain shift was suppressed within 3% even at the beam intensity of 2.5 $\times$ 10$^{6}$ particles per second.

Explicit and Implicit Acquisition of Opacity: Initial Evaluations of A Dual-System Model of Grammar
Creators: name: Carter, William Thomas Jeffrey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Despite OT’s success, opaque alternations prove difficult to capture with constraints, and some      violate the theory’s formal restrictions. Here, I propose a novel account of opacity drawing upon      developments in psychology. Rather than one grammar, I propose a dual-system model with implicit      and explicit mechanisms, a domain-specific OT-like system and a domain-general rule-based system      respectively. While the implicit system can handle most linguistic patterns, special cases like opacity      require explicit acquisition. This predicts an advantage for explicit over implicit learning of opacity,      and that elusive substantive bias may manifest by isolating implicit learners.      In an artificial language experiment, participants learned opaque and transparent metathesis      patterns. Despite participants’ difficulty acquiring the patterns, analysis shows a positive effect of      explicit learning for opaque patterns. Additionally, implicit learners, but not explicit learners, show      higher performance for substantively motivated vs. non-motivated patterns. These results tentatively      support the dual-system account, and further exploration is warranted.

description: Infolge der mechanischen Unterstützung der Gefäßwand nach Stentimplantation kann eine akute Durchmesservergrößerung gegenüber konventioneller Ballonangioplastie (PTCA) erreicht und die Restenoserate gesenkt werden. Eine ausreichende Widerstandsfähigkeit gegenüber äußeren Kräften ist eine Grundvoraussetzung für optimale Ergebnisse in der Stentapplikation. Aufgrund der Vielzahl der verwendeten Materialien und Gestaltungsprinzipien bestehen große Unterschiede in dem mechanischen Verhalten der kommerziell verfügbaren Stents. Die Kenntnis dieser Verhaltensweisen stellt eine essentielle Grundlage einer an die Läsion angepaßten Stentauswahl dar. Obwohl bisher verschiedene Studien das Stentverhalten analysierten, fehlt es aufgrund unterschiedlicher Prüfverfahren an einer Vergleichbarkeit der Ergebnisse. Ziel dieses Beitrages ist die parallele Untersuchung von acht aktuellen Stenttypen. Zu diesem Zweck wurde eine Ultraschall-Meßvorrichtung zur standardisierten, quantitativen Evaluation der kompressiv-mechanischen Eigenschaften von Koronarstents entwickelt. Mit Hilfe dieser Vorrichtung konnte darüberhinaus der Einfluß der Stentimplantation auf das radiale Dehnungsverhalten der Arterienwand untersucht werden.

description: Expertise has been proposed as an important moderator of inattentional blindness. However, research on the topic has produced inconsistent results. While some studies show that expertise reduces inattentional blindness , other studies have found there to be no effect of expertise, or even that it increases inattentional blindness. We hope to shed light on these inconsistencies by conducting a meta-analysis on studies examining the influence of expertise on inattentional blindness.
Unified dark matter: constraints from galaxies and clusters

description: Unified dark matter models are appealing in that they describe the dark sector in terms of a single component. They however face problems when attempting to account for structure formation: in the linear regime, density fluctuations can become Jeans stable and oscillate rather than collapse, though it is possible that this difficulty may be circumvented by invoking nonlinear clustering. Here we examine the behaviour in the fully nonlinear regime, of collapsed objects that should mimic standard dark matter haloes. It is shown that the pressure gradient associated with the unified dark matter fluid should be significant in the outer parts of galaxies and clusters, and its effects obervable. In this case, no flat or falling rotation curve is possible for any (barotropic) equation of state with associated sound speed decreasing with density (a necessary condition if the fluid is to behave as pressureless matter at high density). The associated density profile is therefore also incompatible with that inferred in the outer part of clusters. For the prototypical case of the generalised Chaplygin gas, it is shown that this limits the values of the equation of state index $α$ that are compatible with observations to $α\la 0.0001$ or $α\ga 2$. This is in line from what is deduced from linear analysis. More generally, from the expected properties of dark matter haloes, constraints on the sound speed are derived. For the particular case of the generalised Chaplygin gas, this further constrains the index to $α\la 10^{-9}$ or $α\ga 6.7$. For a unified dark matter fluid to mimic dark halo properties, therefore, it needs to have an equation of state such that the pressure gradients are either minimal or which decrease fast enough so as to be negligible at densities characteristic of the outer parts of haloes.

description: Nur wenige Beispiele aus der deutschen heroischen Epenproduktion des 18. Jahrhunderts haben im literaturgeschichtlichen Gedächtnis überdauert, unter ihnen kaum gelesene wie Klopstocks Messias und kontrovers diskutierte wie Goethes Hermann und Dorothea; keinem Autor dieser Zeit konnten vorwiegend seine Epen das literarische Überleben sichern. Die weltliterarischen Beispiele von Homer bis Milton entstammen weithin anderen Literaturen und anderen Zeiten. —Dennoch beflügelten nur wenige Projekte den literarischen Ehrgeiz des aufgeklärten Jahrhunderts so wie der Gedanke an ein großes heroisches „Heldengedicht". Unter der Oberfläche des Bekannten legt Dieter Martin den breiten Strom vergessener epischer Versuche frei. Die umfangreiche, sorgfältige, stilistisch elegante und daher gut lesbare Untersuchung, die nach verschiedenen verstreuten Vorarbeiten dem Komplex erstmals eine konzentrierte Überblicksdarstellung widmet, betritt insofern durchaus Neuland. Daß sie keine einzige Trouvaille zu Tage fördert, wird man dem Autor zuletzt zur Last legen wollen, daß sie nicht alle Wünsche des Lesers befriedigt, wenigstens zum Teil dem bislang unbestellten Feld.

description: We present the broad-band X-ray spectral analysis (0.6-50 keV) of seven Compton-Thick active galactic nuclei (CT-AGN; line-of-sight, l.o.s., column density $>10^{24}$ cm$^{-2}$) candidates selected from the Swift-BAT 100-month catalog, using archival NuSTAR data. This work is in continuation of the on-going research of the Clemson-INAF group to classify CT-AGN candidates at redshift $z<0.05$, using physically-motivated torus models. Our results confirm that three out of seven targets are \textit{bona-fide} CT-AGN. Adding our results to the previously analysed sources using NuSTAR data, we increase the population of bona-fide CT-AGN by $\sim9\%$, bringing the total number to 35 out of 414 AGN. We also performed a comparative study using MyTorus and borus02 on the spectra in our sample, finding that both physical models are strongly consistent in the parameter space of l.o.s. column density and photon index. Furthermore, the clumpiness of the torus clouds is also investigated by separately computing the line-of-sight and average torus column densities, in each of the seven sources. Adding our results to all the previous 48 CT-AGN candidates analysed by the Clemson-INAF research team having NuSTAR observations: we find $78\%$ of the sources are likely to have a clumpy distribution of the obscuring material surrounding the accreting supermassive black hole.

Components of reward-driven attentional bias and impulsivity
Creators: name: Meyer, Kristin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: History of reward biases attentional selection. However, this reward-driven attentional bias (RDAB) has not been investigated within the context of the separable components of facilitated capture and impaired disengagement. Furthermore, separating these components may better clarify the relationship between RDAB and impulsivity. To this end, across 2 experiments, the current study aimed to firstly characterize capture and disengagement in RDAB and secondly test the relationship between components of RDAB and measures of impulsivity. Across both studies participants completed reward-training followed by a modified cueing paradigm using previously rewarded and previously unrewarded stimuli as cues. Results demonstrated robust effects of facilitated capture and significant effects of impaired disengagement, although these effects were restricted to individuals aware of the reward association, either incidentally or explicitly. Across both studies, neither capture nor disengagement independently predicted impulsivity; however, total RDAB predicted impulsivity in Study 1 only. Possible reasons for these findings are discussed.

description: Emission lines indicative of active accretion have been seen on a handful of low-mass companions (M < 30 MJup) to stars. Line variability is ubiquitous on stellar accretors but has never been characterized in detail on low-mass companions and can give insights on the accretion mechanism at play. We investigate the emission line variability of two low-mass companions (M<30 MJup) to stars to understand their accretion mechanisms. Using J-band observations, we analyze the short to long-term variability of the HI Paschen β emission line (1.282 μm) for GQ Lup b and GSC 06214-00210 b. Archival spectroscopic observations are also examined to extend the time span. We compare their line profiles and intensities to more massive accretors and magnetospheric accretion and shock models. Both objects have HI Paschen β flux variability that is moderate at short timescales (< 50 %) and increases at longer timescales (~1000 % on decade timescales), resembling classical T Tauri stars. GQ Lup b's line profiles are compatible with magnetospheric accretion. GSC 06214-00210 b's profiles are reproduced by both magnetospheric accretion and shock models, except for the brightest epoch for which the shock model is highly favored. Both companions have C/O values broadly consistent with solar values. While magnetospheric accretion is favored for GQ Lup b, higher resolution (R > 10000) observations are required to disentangle the two (non-exclusive) line formation mechanisms. The similarity in variability behavior may support similar accretion mechanisms between these low-mass companions and classical T Tauri stars. The significant variability observed at months and longer timescales could explain the low yield of Hα imaging campaigns.

Year: 2022
Subjects: Innovation Ecosystem; Social Innovation; Technology Social Venture; Institutional Change

description: Despite recent technological advancements and new mission-oriented innovation policies, researchers and practitioners have been claiming that existing solutions to the current societal issues are still too fragmented. This calls for further research on how new forms of collaboration can be developed to better address the inherent complexity of such challenges and generate collective responses. We do it through a single case-study that qualitatively explores the emergence process of an ecosystem of actors built around a Technology Social Venture (TSV) with a transformational social mission. Our study contributes to the literature of innovation ecosystems and social innovation by offering a new perspective that 1) goes beyond platforms; 2) combines actors from different sectors with a common social mission; 3) complements the traditional conceptualization of ecosystem adopted by social innovation scholars; 4) analyses the impact of technology on social change processes challenging dominant institutional logics.
Ab-initio overestimation of the topological region in Eu-based compounds

description: An underestimation of the fundamental band gap values by the density functional theory within the local density approximation and associated approaches is a well-known challenge of ab-initio electronic structure computations. Motivated by recent optical experiments [D. Santos-Cottin et al., arXiv:2301.08014], we have revisited first-principle results obtained earlier for EuCd2As2 and extended the computational studies to the whole class of systems EuCd2X2 (X = P, As, Sb, Bi), to EuIn2X2 (X = P, As, Sb), and to nonmagnetic AEIn2As2 (AE= Ca, Sr, Ba) employing a hybrid functional method. We find that our approach provides the magnitude of the energy gap for EuCd2As2 in agreement with the experimental value. Actually, our results indicate that EuSn2As2, BaIn2As2, EuCd2Bi2 and EuCd2SbBi are robust topological insulators, while all other compounds are topologically trivial semiconductors. The trivial band gaps of EuCd2P2, EuCd2As2 and EuCd2Sb2 are in the range of 1.38-1.48 eV, 0.72-0.79 eV and 0.46-0.49 eV, respectively. The topologically trivial Eu-based systems are antiferromagnetic semiconductors with a strong red shift of the energy gap in a magnetic field caused by the exchange coupling of the band states to spins localized on the 4f-shell of Eu ions. Additionally, the EuIn2X2 (X = P, As) compounds show altermagnetic exchange-induced band spin-splitting, particularly noticeable in the case of states derived from 5d-Eu orbitals.

On the Shock Front Thickness in Water and other Molecular Liquids
Creators: name: Hess, Siegfried
Publisher: name: Technische Universität Berlin
Year: 1997
Subjects: subject: 530 Physik
subject: hydrodynamics
subject: shock front thickness
subject: Maxwell relaxation

description: Theoretical explanations are presented for the deviation of the shock front thickness from linear hydrodynamics, as observed by W. Eisenmenger (1964) in water and several molecular liquids for large driving pressure differences. Two mechanisms are proposed, which are based on generalizations of the Maxwell relaxation equation for the friction pressure tensor. One is due to the spatial inhomogeneity and linked with piezo-electric or piezo-tetradic effects. The other is caused by nonlinearities which account for shear thickening.
TO CAP OR NOT TO CAP: CUSPAL COVERAGE INDICATIONS WITH CAD/CAM LITHIUM DISILICATE RESTORATIONS

description: This study was conducted to examine the in vitro fracture resistance of restored premolars with varying preserved cusp widths, and to determine if functional and nonfunctional cusps have different cuspal coverage indications.       Human maxillary premolars were prepared for IPS e.max CAD onlays. Groups 1-4 preserved a varying amount of the functional or nonfunctional cusp, Group 5 reduced both cusps and Group 6 preserved the functional cusp and included added retentive features. The samples were exposed to simultaneous thermocycling and mechanical loading, and were examined visually to determine mode of failure.       The difference in percent failure between the functional cusp groups and nonfunctional cusp groups was statistically significant. No cusp or restoration fractures were observed; all failures were due to debonding of the restoration.       Added retentive features or margin location in relation to occlusion influences the success of CAD/CAM generated lithium disilicate onlays. Thin preserved cusps were not prone to fracture.
