Chorenta reticulata

description: Chorenta reticulata (Dalman, 1817) Figs 10–11 Prionus reticulatus Dalman, 1817: 147. Chorenta reticulata Monné, 2006: 34 (cat.; comb. n.). Chorenta reticulatus Monné & Hovore, 2006: 9 (cat.); Monné & Bezark, 2008: 10. Also collected with Seticeros tunupai sp. n. were specimens of Chorenta reticulata, which is a new distributional record for Bolivia. This species was known to be distributed in southeastern Brazil (Bahia to Rio Grande do Sul) and Argentina (Misiones) (Monné 2006; Monné & Bezark 2008). Those regions are somewhat distant from La Paz in Bolivia, which suggests that the species may also occur in central Brazil (Mato Grosso and Mato Grosso do Sul). In recent years there has been extensive collecting in the Department of Santa Cruz in Bolivia, but no specimen of that species has been found. Figures 6–Ι3. Head, ventral view: 6 Seticeros tunupai sp. n., holotype male 7 idem, paratype female 8 S. aquilus, male 9 idem, female Ι0 Chorenta reticulata, male ΙΙ idem, female Ι2 C. biramiguelus (Santos-Silva, 2004), male Ι3 idem, female. Despite the absence of specimens in southeastern Brazil and middle-eastern Argentina, the specimens collected in Bolivia are consistent with the specimens examined by us (more than 100 specimens from Brazil). Material examined. BOLIVIA: 1 ♁, Department of La Paz, Nor Yungas, street from Caranavi to Coroico, 1600–1800 m, XI.2009 (NDC); 1 ♁, 1 ♀, same data (RPC). MACROTOMINI

description: We consider theoretically two coupled optical waveguides with a varying barrier height along the waveguides direction. The barrier could be constructed by the elongated island with a reduced refractive index (which acts as a potential barrier), such that in the middle region it splits a waveguide into two weakly coupled parts. It is predicted by numerical simulations and analytical consideration that the presence of some imperfection of the system parameters can cause splitting of injected laser beam and one will observe two intensity maximums at the output, while for small imperfections the input and output beam intensity distributions will be the same. The switching between two regimes could be achieved changing spectral width of the beam or refractive index of the island. This nontrivial effect is explained by possibility of transitions between the different eigenstates of the system in the region of large potential barrier heights. The mentioned effect could be used for all-optical readdressing and filtering purposes.

description: Ziel des vorliegenden Artikels ist es, die (Ko-)Konstruktion von Technik und Geschlecht am Beispiel der Darstellung und Thematisierung des Einsatzes der Reproduktionstech-nologien österreichischer Kinderwunschkliniken herauszuarbeiten. Grundlage für die Analyse sind feministische, technikkritische Ansätze. Die Verfahren der assistierten Reproduktion strukturieren neue Verständnisse von Natur. Die Auffassungen von Mutter- sowie Vaterschaft unterliegen einer laufenden Veränderung. Die binären Geschlechterverhältnisse zwischen Frauen und Männer gelten nach wie vor als stabil, obwohl aus feministischer, technikkritischer Sicht ein ambivalentes Verhältnis zwischen Technikeinsatz und vermittelten Geschlechterkate-gorien existiert. Frauen werden meist als alleinige Nutzerinnen gesehen, während Männer in den Hintergrund treten. Technikeinsatz und damit einhergehende medizini-sche Risiken sowie rechtliche Rahmenbedingungen werden mit Hilfe von sozial kon-struierten Zuschreibungen und Wünschen wie guter Mutterschaft und Weiblichkeit gerechtfertigt. Der Technikeinsatz im Bereich der Fortpflanzung und Reproduktion stellt nicht länger ein medizinisches Randphänomen dar. Die Materialität der Repro-duktionsmedizin ist strukturgebend für die neu entstehenden sozialen Normen und Werte.
description: The aim of this article is to elaborate the (co-)construction of technology and gender using the example of presentation and discussion of the use of assisted reproductive technologies in Austria. The analysis is based on feminist, technology-critical approaches. The procedures of assisted reproductive technologies have opened up new under-standings of nature. The concepts of motherhood and fatherhood are subject to constant change. The binary gender relations between women and men are still regarded as stable, although from a feminist, technology-critical point of view there is an am-bivalent relationship between the use of technology and the interfered gender categories. Women are mostly seen as only users, while men are pushed into the background. The use of assisted reproductive technologies and the closely intertwined medical risks or legal regulations are justified with socially constructed attributions and desires such as good motherhood and femininity. Although it is rarely discussed, the use of technology in the discourse of reproduction no longer represents a marginal medical phenomenon. The materiality of assisted reproductive technologies altered the meaning to the newly emerging social norms.
Beam-Energy and System-Size Dependence of Dynamical Net Charge Fluctuations

description: We present measurements of net charge fluctuations in $Au + Au$ collisions at $\sqrt{s_{NN}} = $ 19.6, 62.4, 130, and 200 GeV, $Cu + Cu$ collisions at $\sqrt{s_{NN}} = $ 62.4, 200 GeV, and $p + p$ collisions at $\sqrt{s} = $ 200 GeV using the net charge dynamical fluctuations measure $ν_{+-,dyn}$. The dynamical fluctuations are non-zero at all energies and exhibit a rather modest dependence on beam energy. We find that at a given energy and collision system, net charge dynamical fluctuations violate $1/N_{ch}$ scaling, but display approximate $1/N_{part}$ scaling. We observe strong dependence of dynamical fluctuations on the azimuthal angular range and pseudorapidity widths.

Year: 2010

description: The design of tilt up concrete wall panels was studied in this paper. Design charts were developed to assist the engineer in the analysis of panels under load. Computer simulation of the concrete section was used to obtain the chart data. A computer study of the effect of a number of parameters on the load carrying capacity of wall panels was made. Loading, section properties and support conditions were varied in isolation in an attempt to obtain general trends of how each influences the strength characteristic of a concrete wall panel. A recommended design procedure has been included which utilizes the charts developed.

description: Electron-cooling offers a relatively simple scheme to enable high-luminosity collisions in future electron-ion and hadron colliders. Contemplated TeV-energy hadron colliders require relativistic (sub 100 MeV) high-charge [${\cal O}(\mbox{nC})$] electron beams with a specific transverse eigenemittance partition. This paper discusses the generation of high-charge ($Q\le 3.2$~nC) 40 MeV electron bunches with eigenemittance partition consistent with requirements associated with electron-cooling option for future electron-ion colliders. The supporting experiment was performed at the FAST facility at FermiLab. The data are compared with numerical simulations and the results discussed in the context of beam requirement for future electron-ion colliders.

We find simple explicit expressions for the stress tensor (slightly generalizing the recent result by Haack and Yarom (arXiv:0806.4602)), the full dual bulk metric and an entropy current of this strongly coupled conformal fluid, to second order in the derivative expansion, for arbitrary d>2. We also rewrite the well known exact solutions for rotating black holes in AdS_{d+1} space in a manifestly fluid dynamical form, generalizing earlier work in d=4. To second order in the derivative expansion, this metric agrees with our general construction of the metric dual to fluid flows.

Community Tenure Rights and REDD+: A Review of the Oddar Meanchey Community Forestry REDD+ Project in Cambodia
Creators: name: Yeang, Donal
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2012

description: Tenure rights over land, forest, and carbon have become a contentious issue within REDD+ implementation across the tropics because local communities could be excluded from REDD+ benefits if land tenure or use and access rights are not clear. This study aims to understand and assess tenure arrangements under the first REDD+ demonstration project in Cambodia, the Oddar Meanchey Community Forestry REDD+ Project. In particular, the study explores the following questions: (1) How are tenure rights arranged in the Oddar Meanchey REDD+ Project? (2) Does the tenure regime recognise the rights of local communities to their land and its associated resources? (3) What kind of institutions are put in place to support tenure rights of local communities in the project? The author conducted in-depth semi-structured interviews with key stakeholders and complemented the analysis by participant observation and a review of policy documents and secondary literature. The major finding of this study is that the local communities in the project are still given rights to use and access forest resources, although carbon rights belong to the government.While the government retains ownership over carbon credits, it agreed that at least 50 percent of the net revenue from the sale of carbon credits will flow to participating communities.

Transborder Environmental Justice in Regional Energy Trade in Mainland South-East Asia
Creators: name: Middleton, Carl
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2012

description: Thailand is mainland South-East Asia’s largest energy consumer. Since the early 1990s, community and civil society opposition to new domestic large-scale power projects has strengthened within Thailand. Partly in response and facilitated by deepening regional economic integration, Thailand’s electricity utility, private sector energy, and construction companies have increasingly looked towards neighbouring Laos and Myanmar to supply Thailand’s energy markets. This paper assesses the political economy of Thailand’s power sector development through the lens of distributive and procedural environmental justice, including the role of social movements and civil society in Thailand in reforming the country’s power planning process. The environmental and social costs of domestic power projects and power import projects are discussed. The author concludes that Thailand’s existing energy imports from hydropower projects in Laos and a gas project in Myanmar have exported environmental injustice associated with energy production across borders, exploiting the comparatively weak rule of law, judicial systems, and civil and political freedoms in these neighbouring countries.

description: A relaxation method is employed to study a rotating dense Bose-Einstein condensate beyond Thomas-Fermi approximation. We use a slave-boson model to describe the strongly interacting condensate and derive a generalized non-linear Schrödinger equation with kinetic term for the rotating condensate. In comparison with previous calculations, based on Thomas-Fermi approximation, significant improvements are found in regions, where the condensate in a trap potential is not smooth. The critical angular velocity of the vortex formation is higher than in the Thomas-Fermi prediction.

Translating Thailand’s Protests: An Analysis of Red Shirt Rhetoric
Creators: name: Buchanan, James
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2013

description: From 14 March 2010 onwards, a mass of suea daeng, literally ‘red shirts’, began a prolonged, mass protest in Bangkok, which eventually degenerated into the worst political violence Thailand has seen in its modern history, leaving 91 people dead, around 2,000 injured, and a city smoldering from rioting and arson. This article provides a narrative of the protests and the Red Shirt movement which is informed by my own eye-witness account of the events and built around the translation of Thai language sources I encountered. By translating and analyzing original Thai language sources from the protests, e.g. banners, signs, t-shirts, speeches, and graffi ti, I argue that the Red Shirts have a more sophisticated, far-reaching political philosophy than many give them credit for. Also, as events unfolded, the movement developed and grew beyond its original scope by demanding justice for victims of the military crackdowns and challenging the political role of the monarchy. Both as a political movement and as a sizeable section of the electorate, the Red Shirts have the potential to drastically reconfi gure Thailand’s social and political landscape.

description: We investigate the evolution of superconducting properties by doping non-magnetic impurity in single crystals of YNi2-xPtxB2C (x=0-0.2). With increasing Pt doping the critical temperature (Tc) monotonically decreases from 15.85K and saturates to a value ~13K for x>0.14. However, unlike conventional s-wave superconductors, the upper critical field (HC2) along both crystallographic directions a and c decreases with increasing Pt doping. Specific heat measurements show that the density of states (N(EF)) at the Fermi level (EF) and the Debye temperatures (Theta_D) in this series remains constant within the error bars of our measurement. We explain our results based on the increase in intraband scattering in the multiband superconductor YNi2B2C.

The UBC ring shear device
Creators: name: Bosdet, Bruce W.
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this thesis has been to design and develop a practical apparatus for determining the residual strength of clay soils. To provide background for the study, current knowledge regarding residual strength is reviewed, including the following points. 1. Residual strength, defined as the lowest drained strength a soil can exhibit, is attained at large shear displacements. 2. Residual conditions result when particles located in shear bands within the failure zone become aligned in the direction of shear. 3. Residual strength, derived from interparticle bonding, is influenced by crystal structure and, in active clay minerals, by pore water chemistry. The ring shear test, performed by applying a torsional shear load to an annular shaped specimen, is particularly suited for residual strength determinations because of unlimited uni-directional strain capabilities. The UBC Ring Shear Device was designed to combine versatility with uncomplicated operation. Features of the design are as follows. 1. Variable sample height up to 0.75 inches. 2. Smoothly variable normal stress up to 200 psi delivered through an air piston. 3. Smoothly variable rate of shear from 3-2 inches per year to 9 inches per hour. 4. A non-tilting loading platen which reduces required machine tolerances and improves control of sample losses during testing. 5. Automatic data acquisition. 6. A simple method of sample placement. Residual strength determinations obtained with the UBC Ring Shear Device demonstrate its efficient and effective operation. Minimal supervision is required and test results are easily interpreted. Multi-reversal direct shear tests for residual strength were undertaken for comparison with the ring shear results, but no satisfactory results were obtained due to excess pore pressures within the test specimens. Recommendations for improvements to both ring shear and direct shear devices are given.
Waiting on the Islands of 'Stuckedness': Managing Asylum Seekers in Island Detention Camps in Indonesia: From the Late 1970s to the Early 2000s
Creators: name: Missbach, Antje
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2013

description: This article sheds light on the obstructed mobility of asylum seekers who were passing through Indonesia during their search for permanent and effective protection, and the politics of their detention. The flows of Indochinese asylum seekers who were ‘stored’ in Galang Island between the late 1970s and the mid-1990s, awaiting either their resettlement or repatriation, are compared with more recent arrivals of asylum seekers from the Middle East, many of whom were hosted in open detention facilities on Lombok Island during the mid-2000s. This comparison provides comprehensive background information on how the asylum seekers and their claims for international protection have been handled in Indonesia. Given that Indonesia is not a party to the 1951 Refugee Convention and the 1967 Protocol, Indonesia offers no formal rights to asylum seekers and refugees within its territory. Instead, Indonesia ‘tolerates’ their presence as long as they are under the auspices of the United Nations High Commissioner for Refugees (UNHCR) or the International Organization for Migration (IOM). Highlighting the differences regarding the management of these two distinctive groups of asylum seekers helps to grasp the full scope of ‘stuckedness’ (Hage, 2009) and also helps to understand the varied impacts of obstructed mobility on asylum seekers looking for permanent and effective protection.

description: The phenomena of intermittent and complete synchronization between two out of three identical, magnetically coupled SQUIDs (Superconducting QUantum Interference Devices) are investigated numerically. SQUIDs are highly nonlinear superconducting oscillators/devices that exhibit strong resonant and tunable response to applied magnetic field(s). Single SQUIDs and SQUID arrays are technologically important solid state devices, and they also serve as a testbed for exploring numerous complex dynamical phenomena. In SQUID oligomers, the dynamic complexity increases considerably with the number of SQUIDs. The SQUID trimer, considered here in a linear geometrical configuration using a realistic model with accesible control parameters, exhibits chaotic and hyperchaotic behavior in wide parameter regions. Complete chaos synchronization as well as intermittent chaos synchronization between two SQUIDs of the trimer is identified and characterized using the complete Lyapunov spectrum of the system and appropriate measures. The passage from complete to intermittent synchronization seems to be related to chaos-hyperchaos transitions as has been conjectured in the early days of chaos synchronization.

Congenital heart defects
SUV4-20H1

description: The interdependence of heart and lung development is critical for proper morphogenesis and organ formation in mammals and has been demonstrated at cellular and physiological levels. Epigenetic control of the gene transcriptional network rules the program for cell specification, proliferation, migration and maturation during cardiopulmonary co-development. Sporadic mutations of SUV4-20H1, an enzyme that converts mono-methylated histone H4 lysine 20 to di-methylated form, have been identified in cohorts of human patients with congenital heart disease. However, proof that mutations in SUV4-20H1 cause congenital heart diseases has been missing. Moreover, the role of SUV4-20H1 in regulating cardiac and cardiopulmonary development by modulating chromatin structure and transcription has remained elusive. 
In this study, I deciphered the role of SUV4-20H1 in controlling heart and lung development by inactivating Suv4-20h1 in various cardiopulmonary cell types in vivo. My findings demonstrate that Suv4-20h1 plays pivotal roles in ISL1+ cardiopulmonary progenitor cells, giving rise to smooth muscle cells and myofibroblasts in the postnatal lung. Loss of Suv4-20h1 in these cells leads to chronic obstructive pulmonary disease and pulmonary hypertension. I found that, SUV4-20H1 modulates H4K20me2 deposition at regulatory elements of genes involved in control of the redox state and in inflammatory responses, among others. Loss of H4K20me2 in Suv4-20h1 mutant cells results in accumulation of H4K20me1 and opening of the chromatin, which causes de-repression of multiple target genes. Expression of the mutant form of SUV4-20H1 found in human patients with congenital heart defects in mice recapitulated the human phenotype. Heart defects also developed in mice that still have an intact Suv4-20h1 allele, suggesting that the mutant form of SUV4-20H1 causes dominant-negative effects. Further studies revealed that SUV4-20H1 modulates the formation of phase-separated condensates and the association of the variable lamina-associated domain with the nuclear envelope, which is required to repress cardiac gene expression in a spatio-temporal manner. 
In sum, my results unraveled the complex function of SUV4-20H1 in regulating gene expression by modulating enhancer activity and/or three-dimensional chromatin organization during heart and lung development. A deeper understanding of this key molecule may provide new perspectives for the treatment of pulmonary and cardiac diseases.

description: We report on the growth of single-crystal potassium birnessite (K0.31MnO2*0.41H2O) and present both the average and local structural characterization of this frustrated magnetic system. Single crystals were obtained employing a flux growth method with a KNO3/B2O3 flux at 700 °C. Single-crystal X-ray diffraction revealed an average orthorhombic symmetry, with space group Cmcm. A combination of high angle annular dark field scanning transmission electron microscopy (HAADF-STEM) with atomic resolution energy dispersive X-ray spectroscopy (EDS) demonstrated the layered structure of potassium birnessite with manganese-containing planes well separated by layers of potassium atoms. MnO6 octahedra and the K/H2O planes were clearly imaged via integrated differential phase contrast (iDPC) STEM. Furthermore, iDPC-STEM also revealed the existence of local domains with alternating contrast of the manganese oxide planes, most likely originating from charge ordering of Mn3+ and Mn4+ along the c-axis. These charge-ordered domains are clearly correlated with a reduction in the c-lattice parameter compared to the rest of the matrix. The insight gained from this work allows for a better understanding of the correlation between structure and magnetic properties.

The topological entropy is used to measure the entanglement of different bipartitions of the 2-colex. The dependency of the ground state degeneracy on the genus of the surface shows that the color code can support a topological order, and the contribution of the color in its structure makes it interesting to compare with the Kitaev's toric code. While a qubit is maximally entangled with rest of the system, two qubits are no longer entangled showing that the color code is genuinely multipartite entangled. For a convex region, it is found that entanglement entropy depends only on the degrees of freedom living on the boundary of two subsystems. The boundary scaling of entropy is supplemented with a topological subleading term which for a color code defined on a compact surface is twice than the toric code. From the entanglement entropy we construct a set of bipartitions in which the diverging term arising from the boundary term is washed out, and the remaining non-vanishing term will have a topological nature. Besides the color code on the compact surface, we also analyze the entanglement properties of a version of color code with border, i.e \emph{triangular color code}.

description: Der Mündigkeitsbegriff weist in der Entwicklung von Bildungstheorien seit der Aufklärung einen zentralen Stellenwert auf. In der kumulativen Dissertation wird untersucht, inwiefern dieses klassische pädagogische Motiv als Theorieperspektive für die Offene Kinder- und Jugendarbeit fruchtbar gemacht werden kann. Das Erkenntnisinteresse ist zum einen mit der Beobachtung verbunden, dass in der Vielfalt der Theorie-Konzepte der (Offenen) Kinder- und Jugendarbeit verwandte Begriffe und Konzepte entwickelt und diskutiert wurden, z. B. Demokratiebildung, Partizipation oder Selbstbestimmung in der Mädchen_arbeit, Mündigkeit selbst jedoch eine randständige Rolle im Fachdiskurs einnimmt. Auf den Begriff wird zwar als Zielperspektive Bezug genommen, gleichzeitig wird Mündigkeit als Konzept weder explizit erörtert, noch auf die damit einhergehenden Widersprüche eingegangen. Das erscheint überraschend, wenn Offene Kinder- und Jugendarbeit als ein zentraler Ort der (Demokratie- und subjektorientierten) Bildung verstanden wird. In der Dissertation werden gesellschafts- und selbstkritische (sozial)pädagogische Theorien einbezogen, die die im Mündigkeitsbegriff eingelagerten Spannungsfelder und immanenten Widersprüche berücksichtigen bzw. ermöglichen, diese in ihrer Vielschichtigkeit zu untersuchen. In diesem Zusammenhang werden differenzsensible, machtkritische sowie intersektionale Perspektiven aufgegriffen, wie sie bereits teilweise im (sozial)pädagogischen Mündigkeitsdiskurs entwickelt wurden. Eine auf diese Weise solidarisch gedachte Mündigkeit kann, so die These, als un-/eindeutige Orientierung verstanden werden und so als Analyse- und Reflexionskonzept dazu beitragen, Marginalisierungen differenzierter wahrzunehmen und zu bearbeiten.

description: SNe Ia are good distance indicators because the shape of their light curves, which can be measured independently of distance, varies smoothly with luminosity. This suggests that SNe Ia are a single family of events. Similar correlations are observed between luminosity and spectral properties. In particular, the ratio of the strengths of the SiII λ5972 and λ6355 lines, known as R(SiII), was suggested as a potential luminosity indicator. Here, the physical reasons for the observed correlation are investigated. A Monte-Carlo code is used to construct a sequence of synthetic spectra resembling those of SNe with different luminosities near B maximum. The influence of abundances and of ionisation and excitation conditions on the synthetic spectral features is investigated. The ratio R(SiII) depends ssentially on the strength of SiII λ5972, because SiII λ6355 is saturated. In less luminous objects, SiII λ5972 is stronger because of a rapidly increasing SiII/SiIII ratio. Thus, the correlation between R(SiII) and luminosity is the effect of ionisation balance. The SiII λ5972 line itself may be the best spectroscopic luminosity indicator for SNe Ia, but all indicators discussed show scatter which may be related to abundance distributions.

description: We solve MacArthur's resource-competition model with random species-resource couplings in the `thermodynamic' limit of infinitely many species and resources using dynamical path-integrals a la De Domincis. We analyze how the steady state picture changes upon modifying several parameters, including the degree of heterogeneity of metabolic strategies (encoding the preferences of species) and of maximal resource levels (carrying capacities), and discuss its stability. Ultimately, the scenario obtained by other approaches is recovered by analyzing an effective one-species-one-resource ecosystem that is fully equivalent to the original multi-species one. The technique used here can be applied for the analysis of other model ecosystems related to the version of MacArthur's model considered here.

description: Microbial communities often exhibit complex spatial structures that are important for their
functioning, ecology and evolution. While the role of biochemical interactions has been extensively
studied, it is unclear how physical interactions contribute to the structuring of multispecies
and phenotypically diverse bacterial communities.
Here, we investigate the physical effect of motility, a key bacterial trait, on the spatial
organization of complex communities, using binary bacterial mixtures as a minimal model
system, where one component is motile and the other is not. We observe that large spatial
heterogeneities in the density of non-motile cells arise under the influence of the motile cells,
which themselves remain homogeneous. Using a combination of experiments and quantitative
modelling, we show that this patterning results solely from physical interactions and relies
on two key ingredients: by swimming in circles on the surface, the motile bacteria generate
recirculating hydrodynamic flows that advect non-motile cells, and the breaking of vertical
symmetry by gravity allows local density accumulation. As the configuration of the motile cells
swimming on the surface rearranges, the advection landscape also does, making the density
patterns fluctuate. This new non-equilibrium mechanism for pattern formation in bacteria
belongs to a different class compared to previous models for self-organization in self-propelled
systems, which rely on localized traffic jamming in two dimensions. It is instead similar to
fluctuation-dominated phase ordering in active nematics.
As these density patterns form over a wide range of biologically relevant densities of both
phenotypes, we also investigated their effect on the aggregation of adherent non-motile cells and
on biofilm formation. We found that the activity of the motile cells enhances the aggregation
of non-motile bacteria and that adhesive motile cells promote the formation of complex, threedimensional
biofilm structures, suggesting that motility, together with the ability of motile cells
to aggregate, is important for the early stages of biofilm formation.
These results show how the activity of motile species can shape the spatial organization of
complex microbial communities and highlight the importance of studying the physical interactions
in these communities.

description: Coherent manipulation of an increasing number of qubits for the generation of entangled states has been an important goal and benchmark in the emerging field of quantum information science. The multiparticle entangled states serve as physical resources for measurement-based quantum computing and high-precision quantum metrology. However, their experimental preparation has proved extremely challenging. To date, entangled states up to six, eight atoms, or six photonic qubits have been demonstrated. Here, by exploiting both the photons' polarization and momentum degrees of freedom, we report the creation of hyper-entangled six-, eight-, and ten-qubit Schrödinger cat states. We characterize the cat states by evaluating their fidelities and detecting the presence of genuine multi-partite entanglement. Small modifications of the experimental setup will allow the generation of various graph states up to ten qubits. Our method provides a shortcut to expand the effective Hilbert space, opening up interesting applications such as quantum-enhanced super-resolving phase measurement, graph-state generation for anyonic simulation and topological error correction, and novel tests of nonlocality with hyper-entanglement.

description: Das Ziel dieser Studie ist es, den Einfluss eines initialen vertikalen Kavitätenlinings mittels eines fließfähigen Komposits auf die Füllungsrandqualität in Schmelz und Dentin von Klasse-V-Kavitäten zu untersuchen. Bei gleichem verwendeten Vier-Schritt-Etch-and-Rinse-Adhäsivsystem (Syntac® Classic, Ivoclar Vivadent) sollen unterschiedliche Kompositmaterialien miteinander verglichen werden.
Es wurden 60 karies- und restaurationsfreie humane Weisheitszähne mit standardisierten Klasse-V-Kavitäten mit den Maßen 4 x 3 x 2 mm versehen. Es folgte eine randomisierte Aufteilung in 6 Versuchsgruppen (n=10). Als Adhäsivsystem wurde bei allen Gruppen Syntac® Classic (Ivoclar Vivadent) verwendet. Das Füllen erfolgte jeweils in zwei vertikalen Inkrementen, wobei bei 3 Gruppen das gleiche stopfbare Material für beide Inkremente verwendet wurde und bei 3 Gruppen ein Lining aus fließfähigem Komposit mit anschließender Deckschicht aus stopfbarem Material erfolgte. Vor und nach 10.000 Zyklen thermischer Wechselbelastung zur Alterssimulation im Thermocycler wurden Replikas angefertigt, die mittels Rasterelektronenmikroskop auf Randspaltbildung untersucht und analysiert wurden.
Alle Gruppen zeigten nach thermischer Wechselbelastung Randspaltbildungen in Schmelz und Dentin. Im Zahnschmelz zeigten die Lining-Gruppen nach TC ähnliche Ergebnisse wie die jeweiligen Vergleichsgruppen ohne Lining. Hier konnte die beste Randqualität mit 95 % von Gruppe 2 (Venus® Diamond Flow + Venus®) erzielt werden. Im Dentin erzielten alle Gruppen mit initialem Lining bessere Randqualitäten als in den Vergleichsgruppen ohne Lining. Dabei schnitt Gruppe 4 (Tetric® EvoFlow + Tetric® Prime) mit 77 % ohne signifikante Verschlechterung im Vergleich zur Ausgangssituation vor TC am besten ab. Die schlechtesten Werte wurden sowohl in Schmelz als auch in Dentin von Gruppe 5 (Clearfil Majesty™ ES-2 Universal) erzielt.
Bei Klasse-V-Kavitäten führt ein vertikales Lining mit Tetric® EvoFlow in Kombination mit einer Deckschicht aus Tetric® Prime zu einer signifikant verbesserten Randqualität im Dentin. Bei den anderen untersuchten Materialien führte das Lining zwar zu einer geringfügigen-, jedoch zu keiner signifikanten Verbesserung der Randqualität in Schmelz und Dentin.
