description: Giga-bit level IC design has already been progressed by GaAs MESFET technology. This work is to present a lOGbps ultra-high speed design with sensitive decision circuit using 0.5 um gate MESFET technology. The decision circuit is basically consisted of Master-Slave type D-FF, source-coupled FET differential amplifier named Source-Coupled FET Logic (SCFL) circuit. This GaAs digital SCFL circuit includes two FETs(E-mode MESFET and D-mode MESFET) and also includes some of resistors and diodes between input signals and ground. Source-follower generally minimizes the load of the SCFL and is included in the output node to improve the performance. Based on the fabricated 0.5 um devices, process parameters are successfully extracted and optimized to check for 10 GHz operation from the D-FF SCFL decision circuit using circuit simulator before real GaAs IC process fabrication. The GaAs SCFL circuit was operated at 10 Gbps ultra-high speed level, which is designed for future high speed optical receivers.

description: Finland, Estonia, Latvia, Lithuania, and Poland – all countries founded after World War I on the ruins of the Russian Empire – had to face more complex challenges than most of the stable western states. The countries of East Central Europe needed to cope with the direct consequences of the war, to construct a stable currency system, practically from scratch, and revise their trade relations. The transportation network had to be adjusted to the delineated borders. There were also a number of grave social problems to be attended to. The capital market, seriously damaged by inflation, had to be built anew.

The long-term history of plant communities on southeastern Vancouver Island based on vegetation resurveys and phytolith analysis
Creators: name: McCune, Jenny Lyn
Publisher: name: University of British Columbia
Year: 2013

description: Terrestrial plant communities are complex systems, and major storehouses of global biodiversity. The composition of a plant community today is contingent on conditions that have occurred throughout its history. Therefore, an understanding of current plant community structure requires an understanding of its origin and its variability over time. In this thesis, I investigate the history of plant communities on southeastern Vancouver Island, Canada, at two time scales. These communities are now highly fragmented and threatened by human disturbance, but they also have a long history of management by indigenous peoples. To quantify changes due to recent urbanization, I resurveyed 184 vegetation plots originally surveyed in 1968. I documented striking increases in plot-level and total species richness, but a decline in the variation in plant community composition between plots, a phenomenon called ‘biotic homogenization’. Exotic species were more likely than natives to increase over time, but exotic colonizations were not correlated with biotic homogenization or native declines. Plant life history traits predicted colonizations based on landscape context within 500m of a plot, but extirpations were rare and much less predictable, suggesting time lags in plant community response to landscape disturbance and fragmentation, and a potential extinction debt. I used plant microfossils called phytoliths extracted from soil to investigate changes in plant communities prior to European settlement. I established that the ratio of asterosclereid phytoliths produced in the needles of Douglas-fir (Pseudotsuga menziesii) to the rondel phytoliths produced by most grasses can accurately distinguish between Douglas-fir dominated forests and Garry oak (Quercus garryana) savannah habitats today. I then examined changes in this ratio with depth at seven local sites, finding that infilling by Douglas-fir forest first began at different times, depending on the site. However, some savannah sites have supported grassy vegetation for at least two thousand years. Active management to maintain open conditions will be necessary to preserve rare species that evolved in these conditions. These investigations demonstrate that examining the history of plant communities can reveal surprises and challenge assumptions about how they respond to disturbance. This knowledge can improve ecological theory, and inform management and conservation strategies.

The combined X-ray luminosity function of all the 996 sources within the optical \D of the sample galaxies is well described by a broken power law with a break at 2.71$\times$\te \lum and is close to the Eddington limit for a 1.4\Msun neutron star. Out of the 996, about 63\p of the sources have their X-ray luminosities in the range between few\tim\ts to 2.0 \tim \tn \lum and are like normal LMXBs; about 15-20\p with luminosities $

description: The cross-correlation between the integrated Sachs-Wolfe (ISW) effect and the large scale structure (LSS) is a powerful tool to constrain dark energy and alternative theories of gravity. In this paper, we obtain observational constraints on kinetic gravity braiding from the ISW-LSS cross-correlation. We find that the late-time ISW effect in the kinetic gravity braiding model anti-correlates with large scale structures in a wide range of parameters, which clearly demonstrates how one can distinguish modified gravity theories from the LCDM model using the ISW effect. In addition to the analysis based on a concrete model, we investigate a future prospect of the ISW-LSS cross-correlation by using a phenomenological parameterization of modified gravity models.

description: In der vorliegenden Arbeit wurden neuartige künstliche Bindeproteine entwickelt, die auf Ca2+-bindenden Gerüstproteinen der βγ-Kristallin-Familie basieren. Diese fungieren als molekulare Schalter, die eine hohe Affinität zum Zielprotein im Ca2+-gebundenen und eine geringere Bindungsstärke im Ca2+-freien Zustand aufweisen. Protein S aus M. xanthus wurde als scaffold zur Generierung künstlicher Bindeproteine verwendet, die Ca2+-abhängig sfGFP binden. Durch die Randomisierung von 15 Aminosäurepositionen wurde eine Protein S Bibliothek erstellt und über Ribosomen-display Varianten mit bis zu sub-nanomolaren Affinitäten und selektiver Bindung erhalten. Es wurde gezeigt, dass in Abwesenheit von Ca2+ nicht nur die Komplexbildung der Protein S-Variante und sfGFP unterbunden, sondern auch bestehende Komplexe dissoziiert werden können. Eine Variante wurde auf einer Säulenmatrix immobilisiert und damit die Ca2+-abhängige chromatographische Reinigung von sfGFP aus Zellextrakten gezeigt.
description: In this work a new class of artificial binding proteins was developed, which are based on Ca2+-sensitive scaffolds of the βγ-crystallin family. These new binding proteins act as molecular switches, that show a high affinity to the target structure in the presence of Ca2+ and a low affinity in the Ca2+-free state. Protein S of M. xanthus was used as a scaffold for the generation of Ca2+-sensitive artificial binding proteins against sfGFP. By randomization of 15 positions a Protein S library was constructed and ribosome display was used for selection. Variants with affinities as low as sub-nM interaction could be isolated. It could be shown that the complex formation of Protein S and sfGFP could be prevented by the absence of Ca2+ and already formed complexes could be dissociated by titration of Ca2+ from the system. One of the Protein S variants was immobilized on the surface of a column matrix and the Ca2+-dependent purification of sfGFP from crude cell extracts was demonstrated.

description: In this paper, we will investigate a metal- insulator-semiconductor	(MIS)	like InGaAs/GaAs doped-channel structure both in theoretical analysis and experiment. First, a charge control model is employed to simulate the basic electronic properties of the doped-channel field-effect transistor (FET). Then, a practical device is fabricated and processed. From the results, we can find that the device shows good transistor characteristics. A high breakdown voltage of 17.4 V, a maximum drain saturation, current of 930 mA/mm, a maximum transconductance of 235 mS/mm, and a very broad gate voltage swing larger than 3V with the transconductance higher than 200mS/mm are obtained for a 2x100 um2 gate-dimension FET. From the comparison, we find that the experiments are in good agreement with the theoretical simulations. The, performances provide a promise of the proposed device to be a good candidate for practical circuit applications.

description: Für Manganoxide wird auf Grund unterschiedlicher Besetzung des Mangan 3d-Orbitals eine starke Variation von physikalischen und chemischen Eigenschaften erwartet. Sie werden unter Anderem als Katalysatoren, Sensoren und Elektrodenmaterialien in Lithium Batterien diskutiert. Drei verschiedene Manganoxide wurden auf Pt(111) präpariert. Zur Ermittlung der bedeckungs-abhängigen Schwingungseigenschaften wurde hochauflösende Elektronenenergieverlustspektroskopie (HREELS) verwendet. Strukturelle Informationen wurden mittels niederenergetischer Elektronenbeugung (LEED) gewonnen und die thermische Stabilität wurde mit Hilfe thermischer Desorptionsspektroskopie (TPD) untersucht. Die Manganoxide wurden als MnO(100), als Mn3O4 und als sauerstoffterminiertes MnO(111) identifiziert. Sie lassen sich deutlich an Hand ihrer charakteristischen Schwingungsspektren unterscheiden. Die Messungen können daher als Referenz für die Untersuchung chemischer Reaktionen der Manganoxide verwendet werden. So konnten mit diesen Informationen thermisch bzw. chemisch induzierte Phasenübergänge (Oxidation und Reduktion) zwischen diesen Manganoxiden untersucht werden. Des Weiteren wurde die Bedeckungsabhängigkeit der Schwingungsspektren von MnO(100) mit verschiedenen theoretischen Modellen verglichen.
description: For manganese oxides a strong variety in there physical and chemical properties is expected depending on the filling of the manganese 3d-orbital. They are discussed as catalysts, as sensors, and as electrode material in lithium batteries. Three different manganese oxides have been prepared on Pt(111). High resolution electron energy loss spectroscopy (HREELS) has been used to get informations about coverage dependent vibrational properties of the MnO films. The structure has been characterized by low electron energy diffraction (LEED) and the thermal stability of the manganese oxide films was investigated by temperature programmed desorption (TPD). The manganese oxides have been identified as MnO(100), as Mn3O4, and as oxygen terminated MnO(111). The oxides can clearly be distinguish by there HREEL-spectra. Therefore this informations can be used as a reference for the investigation of chemical reactions of the manganese oxides. I this way the thermal and chemical induced phase transitions between these manganese oxides (oxidation and reduction) has been investigated. Additional the thickness dependent vibrational spectra of MnO(100) have been compared to different theoretical models.

description: We introduce the notion of relevant information loss for the purpose of casting the signal enhancement problem in information-theoretic terms. We show that many algorithms from machine learning can be reformulated using relevant information loss, which allows their application to the aforementioned problem. As a particular example we analyze principle component analysis for dimensionality reduction, discuss its optimality, and show that the relevant information loss can indeed vanish if the relevant information is concentrated on a lower-dimensional subspace of the input space.

description: Simulation is widely used to investigate real-world systems in a large number of fields, including clinical trials for drug development, since real trials are costly, frequently fail and may lead to serious side effects. This paper is a survey of the statistical issues arising in these simulated trials. We illustrate the broad applicability of this investigation tool by means of examples selected from the literature. We discuss the aims and the peculiarities of the simulation models used in this context, including a brief mention of the use of metamodels. Of special interest is the topic of the design of the virtual experiments, stressing similarities and differences with the design of real life trials.
Since it is important for a computerized model to possess a satisfactory range of accuracy consistent with its intended application, real data provided by physical experiments are used to confirm the simulator: we illustrate validating techniques through a number of examples. We end the paper with some challenging questions on the scientificity, ethics and effectiveness of simulation in the clinical research, and the interesting research problem of how to integrate simulated and physical experiments in a clinical context.

description: Cystatin B ist ein endogener Proteinaseinhibitor der Typ 1-Cystatine. CSTB hemmt in vitro verschiedene Cysteinproteinasen der Papainfamilie durch nicht-kovalente, reversible Bindung. Mutationen im CSTB-Gen, die zu einer verringerten CSTB-Expression führen, sind verantwortlich für die progressive myoklonische Epilepsie (EPM1). Weitere Funktionen von CSTB, z.B. in der Tumorbiologie, werden diskutiert, Funktionen die wesentlich für die Ausprägung der Charakteristika maligner Tumoren sind und die sich nicht allein auf seine Rolle als Inhibitor zu beschränken scheinen. Für weiterführende Untersuchungen zur Funktionsaufklärung von CSTB auf Proteinebene wurden im Rahmen der vorliegenden Arbeit 6 hochspezifische monoklonale Antikörper gegen CSTB generiert. Sie wurden nach einer modifizierten Variante der Methode von Köhler und Milstein entwickelt. Im ersten Teil der Arbeit wurden die monoklonalen Antikörper gegen CSTB charakterisiert (Epitope mapping, Bindungskonstanten). Im zweiten Teil wurde mit Hilfe der gereinigten Antikörper ein quantitativer Sandwich-ELISA etabliert, welcher für die Bestimmung von CSTB im Plasma von Karzinom-Patienten genutzt werden soll. Als Nachweis für die Eignung des entwickelten Sandwich-ELISA zur CSTB-Bestimmung im Plasma wurde eine Pilotstudie mit 45 Proben von gesunden Probanden und 32 Proben von HCC-Patienten durchgeführt.

description: The experience of teaching for several years in different degree courses pressed me to use new tools and methods to make use of. Connecting general trend of teaching all over the world this paper want to reply to the following research question: “what challenges we are facing in teaching accounting and reporting in tourist entities?”.
Research design is oriented to deep study international literature about the state of art of teaching accounting and above all social and environmental accounting and reporting(CSEAR)( Gray, Owen, Adams, 1996, Tinker, Gray, 2003; Tinker, 2005; Gray , Guthrie, 2007), because I think that this field is very important for service enterprises, especially for tourist ones. The importance is given by disclosure and democracy that is at the base of CSEAR process and my interest to safeguard people and environment in tourist entities and destinations( Garrone, 2005). 
There are different aspects of tourism and poverty is often connected with tourism. 
In my idea, in which I wont to change a peace of world, I want to present some reflections about How to teach accounting in tourism to give student the availability to understand the constructive role of accounting but at the same time the bad role of it at the same to serve power and exploitation.

description: We study the time-dependence of quantum entanglement between two Unruh-DeWitt detectors, one at rest in a Minkowski frame, the other non-uniformly accelerated in some specified way. The two detectors each couple to a scalar quantum field but do not interact directly. The primary challenge in problems involving non-uniformly accelerated detectors arises from the fact that an event horizon is absent and the Unruh temperature is ill-defined. By numerical calculation we demonstrate that the correlators of the accelerated detector in the weak coupling limit behaves like those of an oscillator in a bath of time-varying "temperature" proportional to the instantaneous proper acceleration of the detector, with oscillatory modifications due to non-adiabatic effects. We find that in this setup the acceleration of the detector in effect slows down the disentanglement process in Minkowski time due to the time dilation in that moving detector

description: In this work we study the Nekrasov-Shatashvili limit of the Nekrasov instanton partition function of Yang-Mills field theories with N=2 supersymmetry and gauge group SU(n). The theories are coupled with fundamental matter. The equation that determines the density of eigenvalues at the leading order in the saddle-point approximation is exactly solved. The dominating contribution to the instanton free energy is computed. The requirement that this energy is finite imposes quantization conditions on the parameters of the theory that are in agreement with analogous conditions that have been derived in previous works. Using methods borrowed from the theory of matrix models, a field theoretical expression of the full instanton partition function is derived. It is checked that in the Nekrasov-Shatashvili (thermodynamic) limit the action of the field theory obtained in this way reproduces exactly the equation of motion used in the saddle-point calculations.

description: Soil-steel structures are designed and constructed worldwide for use in civil infrastructure and construction industries. As a result, extensive work has been devoted to understanding the corrosion of zinc and galvanized steel yielding the development of various corrosion models worldwide. Canada does not have a corrosion model required for use in design, but engineers and contractors often use that developed in the United States by the American Association of State Highway and Transportation Officials. This corrosion model defines the recommended range of pH, chloride concentration and soluble sulphate concentration as well as minimum resistivity for unsaturated soil applications. However, these design recommendations and associated corrosion model are often misused in aqueous environments. As a result, many structures have demonstrated significant evidence of premature corrosion raising concerns with the suitability of this corrosion model. Field testing was conducted on both mechanically stabilized earth retaining walls as well as corrugated steel pipe. Steel samples were extracted for analyses with scanning electron microscope and energy dispersive x-ray spectroscopy while water samples were collected to determine the properties causing degradation. Linear polarization resistance was also completed on two mechanically stabilized earth walls to obtain in-situ corrosion rates. To complement field work, laboratory experiments were conducted on galvanized steel samples in electrolytes simulating environments satisfying design criteria recommending by the American Association of State Highways and Transportation Officials as well as outside the scope of this model. Relative corrosion rates were calculated from results obtained from accelerated corrosion testing and sample surfaces were analyzed with the use of a scanning electron microscope. Through laboratory experimentation and field testing it has been discovered that the hardness of water affects the formation of the outermost protective layer on zinc articles, the zinc patina. The following dissertation challenges the appropriateness of durability design criteria and associated corrosion model, defined by the American Association of State Highway and Transportation Officials, for use in aqueous environments while offering guidance on the development of more suitable guidelines for conditions other than unsaturated soil.

However these populations adopt Roman Law following the discipline established by the Theodosian Code, which although starting to assert the supremacy of the imperial right, still declares the indispensability of jurisprudential principles, according to the most genuine western tradition.
VAFB-1983-09: The Story of Marshallia Ranch, a History Dating Back to the Olivera Adobe Built in 1837
Creators: name: The Office Of History, 1st Strategic Aerospace Division
Year: 1983

description: This document is a report detailing the story of the Marshallia ranch house. It is the oldest structure on VAFB, has been a landmark for more than a century, surviving drastic remodellings and the ravages of two fires. Mexicans and Americans, ranchers and missile engineers, wars and depressions, have all played a role in its destiny. Its fate has been linked with the "Rancho de Jesus Maria," which covered nearly one-half of the land on present-day VAFB. The ranch house's history mirrors the changes which have transformed this corner of California from isolated grazing land to space age gateway.

description: La forza del paradigma metaforico organicistico, che compenetra diversi aspetti della poetica di Arnold Schönberg, risiede non solo nel fascino di una descrizione dinamica dell’opera che tiene conto della sua esperienza nel tempo, ma soprattutto nel fatto che esso, in seno alla riflessione del compositore viennese, offre coerenti risposte a fondamentali quesiti come il tema dell’ispirazione, dell’evoluzione del genio, della filosofia della storia della musica.

Per estensione del campo metaforico, Schönberg definisce la stessa essenza del genio in termini organicistici: colui che crea opere organiche possiede una natura organica e la vita del genio è teleologica, al pari della sua opera, tanto che la sua essenza è predicabile nei termini di una Entwicklung, di uno sviluppo organico.

I quattro scritti Bei Arnold Schönberg: Ein Interview (1909), Schaffensqual (1928), How One Becomes Lonely (1937) e My Evolution (1949) rappresentano altrettante stesure di questa Entwicklung, scritte da Schönberg in periodi diversi della propria maturazione artistica. Esse gettano luce sul modo in cui il compositore viennese, nel raccontare la propria evoluzione, abbia periodicamente riletto e risistemato la propria opera. Da narratore, offre volta per volta una tranche de vie: ora evidenzia una certa opera, ora la passa sotto silenzio, ora dà maggiore peso ad una certa scelta compositiva, ora minore. Ogni volta che riordina la propria evoluzione artistica, egli riorganizza narrativamente il suo passato, ne propone una nuova “edizione” ma, in ogni caso, segue sempre un filo coerente degli eventi, orientato teleologicamente verso il presente.

description: To investigate the fundamental principles of H2 formation in a giant molecular cloud (GMC), we derive the HI and H2 surface density (Sigma_HI and Sigma_H2) images of the Perseus molecular cloud on sub-pc scales (~0.4 pc). We use the far-infrared data from the Improved Reprocessing of the IRAS Survey and the V-band extinction image provided by the COMPLETE Survey to estimate the dust column density image of Perseus. In combination with the HI data from the Galactic Arecibo L-band Feed Array HI Survey and an estimate of the local dust-to-gas ratio, we then derive the Sigma_H2 distribution across Perseus. We find a relatively uniform Sigma_HI ~ 6-8 Msun pc^-2 for both dark and star-forming regions, suggesting a minimum HI surface density required to shield H2 against photodissociation. As a result, a remarkably tight and consistent relation is found between Sigma_H2/Sigma_HI and Sigma_HI+Sigma_H2. The transition between the HI- and H2-dominated regions occurs at N(HI)+2N(H2) ~ (8-14) x 10^20 cm^-2. Our findings are consistent with predictions for H2 formation in equilibrium, suggesting that turbulence may not be of primary importance for H2 formation. However, the importance of a warm neutral medium for H2 shielding, an internal radiation field, and the timescale of H2 formation still remain as open questions. We also compare H2 and CO distributions and estimate the fraction of "CO-dark" gas, f_DG ~ 0.3. While significant spatial variations of f_DG are found, we do not find a clear correlation with the mean V-band extinction.

description: I più antichi formulari (intorno al 600 d.C) provengono da città che pur sotto la domina-zione franca (Angers) o gotica (Cordova) hanno conservato alla meglio le strutture ammini-strative romane ereditate e hanno continuato a vivere secondo il diritto romano. Questo però era soltanto quello della Lex Romana Visigothorum, anche nel regno dei Franchi. Tuttavia penetrano con forza anche concetti giuridici germanici: a Cordova il diritto della Lex Visigo-thorum, presso i Franchi il diritto della Lex Salica e il diritto consuetudinario franco. Già, però, nel primo VII secolo anche un franco - un uomo di Chiesa - redige una propria raccolta per i negozi giuridici secondo il diritto franco, con varie reminiscenze del diritto romano. Nelle raccolte dell'VIII secolo (Bourges, Tours e Clermont) si trovano spesso espliciti riferimenti al diritto romano, ma dal punto di vista del contenuto sono sempre più fortemente influenzate dal diritto franco. Oggetto delle formule sono molto spesso negozi relativi a terreni: vendite e donazioni alla Chiesa e regali di nozze. Inoltre riguardano gli schiavi: vendite, manomissioni e, frequentemente in modo vistoso, vendite di se stessi per debiti; naturalmente riguardano anche i mutui. Alla base delle singole formule stanno di regola negozi reali della città in questione.
Die ältesten Formelsammlungen (um 600 n. Chr.) stammen aus Städten, die auch unter fränkischer (Angers) beziehungsweise gotischer Oberherrschaft (Cordoba) die ererbten römi-schen Verwaltungsstrukturen so gut es ging beibehalten hatten und weiterhin nach römischem Recht lebten. Dieses war freilich nur mehr das der Lex Romana Visigothorum, auch im Fran-kenreich. Trotzdem drangen auch germanische Rechtsvorstellungen mit Macht ein: in Cordoba das Recht der Lex Visigothorum, bei den Franken das Recht der Lex Salica und fränkisches Gewohnheitsrecht. Schon im frühen 7. Jahrhundert hat aber auch ein Franke – ein Mann der Kirche – eine eigene Sammlung für Rechtsgeschäfte nach fränkischem Recht angelegt, mit mannigfachen Reminiszenzen an das römische Recht. In den Sammlungen des 8. Jahrhunderts (Bourges, Tours und Clermont) finden sich oft ausdrückliche Bekenntnisse zum römischen Recht, aber inhaltlich sind sie immer stärker von fränkischem Recht beeinflusst. Gegenstand der Formeln sind sehr oft Grundstücksgeschäfte: Verkäufe und Schenkungen, an die Kirche und zur Hochzeit. Außerdem geht es um Sklaven: Verkäufe, Freilassungen und, auffallend häufig, Selbstverkauf wegen Überschuldung; natürlich auch Darlehen. Den einzelnen Formeln lagen in der Regel wirkliche Geschäfte in der betreffenden Stadt zugrunde.

description: Prediction and control of the dynamics of complex networks is a central problem in network science. Structural and dynamical similarities of different real networks suggest that some universal laws might accurately describe the dynamics of these networks, albeit the nature and common origin of such laws remain elusive. Here we show that the causal network representing the large-scale structure of spacetime in our accelerating universe is a power-law graph with strong clustering, similar to many complex networks such as the Internet, social, or biological networks. We prove that this structural similarity is a consequence of the asymptotic equivalence between the large-scale growth dynamics of complex networks and causal networks. This equivalence suggests that unexpectedly similar laws govern the dynamics of complex networks and spacetime in the universe, with implications to network science and cosmology.

description: Gli scritturali nel regno dei Franchi erano nei secoli bui dal VI all'VIII secolo, nelle città della Gallia meridionale (come si evince dalle raccolte di formule franche) solitamente come prima gli scritturali cittadini: amanuenses (Angers, Tours, Clermont Ferrand), nelle grandi città come Parigi, notarii; costoro redigevano anche semplici documenti privati. Sotto Carlo Magno i notarii cittadini di Bourges si trovano in gran numero sotto un notaio di grado più elevato (professor). Carlo istituisce dei notarii anche presso i missi reali, i conti, i vescovi e abati. Nei documenti del regno orientale dei Franchi ho incontrato solo clerici - gli scritturali stavano evidentemente al servizio della Chiesa: notarii a Le Mans, Châlons sur Marne, Semur e so-prattutto a Weißenburg. Anche in Italia i notarii erano scritturali al servizio della Chiesa, mentre l'evoluzione di scritturali laici si deve alla riforma di Giustiniano sulla documentazione: le città davano le concessioni e sorvegliavano i loro scritturali (tabelliones, anche forenses), un sistema, che dall'XI secolo si doveva poi imporre in tutto il mondo occidentale.
Urkundenschreiber im fränkischen Reich waren in den dunklen Jahrhunderten, vom 6. bis zum 8. Jahrhundert, in den Städten des südlichen Gallien (wie den fränkischen Formelsam-mlungen zu entnehmen ist) meist nach wie vor städtische Schreiber: amanuenses (Angers, Tours, Clermont Ferrand), in größeren Städten wie Paris notarii; sie schrieben auch schlichte Privaturkunden. Unter Karl dem Großen begegnen städtische notarii in Bourges in größerer Zahl unter einem obersten Notar (professor). Karl richtete notarii auch bei den königlichen missi, Grafen, den Bischöfen und Äbten ein. In Urkunden aus dem östlichen Frankenreich – ich habe nur kirchliche gefunden – standen die Urkundenschreiber offenbar im Dienst der Kirche: notarii in Le Mans, Châlons sur Marne, Semur und vor allem Weißenburg. Auch in Italien waren notarii Schreiber in kirchlichem Dienst, während die Entwicklung der weltlichen Urkundenschreiber von Justinians Reform des Urkundenwesens geprägt wurde: Die Städte konzessionierten und überwachten ihre Schreiber (tabelliones, auch forenses), ein System, das seit dem 11. Jahrhundert sich dann im ganzen Westen durchsetzen sollte.
A Mayer-Vietoris formula for persistent homology with an
application to shape recognition in the presence of occlusions

description: In  algebraic topology it is well-known that, using the
Mayer-Vietoris sequence, the homology of a space $X$ can be
studied splitting  $X$ into subspaces $A$ and $B$ and computing the homology of  $A$, $B$, $A\cap B$. A natural question is to which an extent persistent homology benefits of a similar property. In this paper we show that persistent homology has a Mayer-Vietoris sequence that in general is not exact but only of order two. However, we obtain a Mayer-Vietoris formula involving the ranks of the persistent homology groups of $X$, $A$, $B$ and $A\cap B$ plus  three extra terms. This implies that topological
features of $A$ and $B$ either survive as topological features of $X$ or are hidden in $A\cap B$. As an application of this result, we show that persistence diagrams are able to recognize an occluded shape by showing a common subset of points.

description: Most of known multipartite Bell inequalities involve correlation functions for all subsystems. They are useless for entangled states without such correlations. We give a method of derivation of families of Bell inequalities for N parties, which involve, e.g., only (N-1)-partite correlations, but still are able to detect proper N-partite entanglement. We present an inequality which reveals five-partite entanglement despite only four-partite correlations. Classes of inequalities introduced here can be put into a handy form of a single non-linear inequality. An example is given of an N qubit state, which strongly violates such an inequality, despite having no N-qubit correlations. This surprising property might be of potential value for quantum information tasks.
