description: Given a probability distribution on an open book (a metric space obtained by gluing a disjoint union of copies of a half-space along their boundary hyperplanes), we define a precise concept of when the Fréchet mean (barycenter) is sticky. This nonclassical phenomenon is quantified by a law of large numbers (LLN) stating that the empirical mean eventually almost surely lies on the (codimension $1$ and hence measure $0$) spine that is the glued hyperplane, and a central limit theorem (CLT) stating that the limiting distribution is Gaussian and supported on the spine. We also state versions of the LLN and CLT for the cases where the mean is nonsticky (i.e., not lying on the spine) and partly sticky (i.e., is, on the spine but not sticky).

description: Sucroseesterstearat-Matrixformulierungen wurden mithilfe von Vitaminen bezüglich Ihres Freisetzungsverhalten und -mechanismus charakterisiert. Eine verzögerte Freisetzung wurde erfolgreich für Granulate, Minitabletten und Pellets erreicht. Besonders die Anwendung von Schmelztechnologien führte zu langen Freisetzungsperioden. Das thermotrope, flüssigkristalline Verhalten von amphiphilen Kohlenhydraten spielt beim Einsatz von Schmelztechnologien eine große Rolle. Diffusion wurde mittels mathematischem modelling als Freisetzungsmechanismus für nahezu alle Formulierungen identifiziert. Die Matixbildung wurde mit Magnet-Resonanz-Imaging beschrieben. Einzelne Sucroseesterstearate zeigen eine Quellung andere verhalten sich ähnlich wie Fetteinbettungsformen. Die Freisetzungsrate aus Sucroseesterstearat-Matrixformulierungen wird vor allem durch die Konzentration des Sucroseesters in der Formulierung, den Sucroseestertyp, die Wasserlöslichkeit und Molekülgröße der aktiven Substanz bestimmt. Durch die Wahl der Herstellmethode kann die Freisetzung zusätzlich beeinflusst werden. Sucroseester sind eine interessante Substanzgruppe, die als Matrixformulierungen bisher wenig Beachtung gefunden haben und nur wenig beschrieben waren.

description: Die humane Myt1 Kinase ist an der Regulation des Zellzyklus beteiligt. Systematische Substratstudien in dieser Arbeit zeigten, dass dieses Enzym restriktiv in der Wahl seiner Substrate agiert. Während vereinfachte Proteine (Peptide) nicht phosphoryliert wurden, erwiesen sich die Vollproteine als gute Substrate. Da die Verwendung von Proteinsubstraten in Screeningassays viele Probleme mit sich bringt, wurde ein zeitaufgelöster Fluoreszenzresonanzenergietransfer- basierter Kinasebindungsassay etabliert und ein erstes Inhibitionsprofil ermittelt. Als Assayalternative wurde zudem ein auf Fluoreszenzpolarisation basierender Bindungsassay entwickelt und neue, vormals unbekannte Hemmstoffe identifiziert. Schließlich wurden Peptid-Microarrays verwendet, um die Substratproblematik zu lösen. Tatsächlich konnten zwei Peptide aus dieser Herangehensweise auch in Lösung als Myt1 Substrate bestätigt und validiert werden.
description: Myt1 is an important cell cycle regulating kinase. Herein, systematic substrate studies revealed the kinase to be restrictive in terms of substrate acceptance. While simplified proteins (peptides) were not accepted, full-length proteins were efficiently phosphorylated. Since protein substrates are problematic in screening assays, a kinase binding assay based on time-resolved fluorescence resonance energy transfer was established and a first inhibition profile for this kinase was obtained. As an alternate assay, a fluorescence polarization based kinase binding assay was developed and formerly unknown inhibitors were identified. Finally, peptide microarray studies helped resolve the Myt1 substrate issue. Indeed, two peptides derived from this approach could be verified and validated as Myt1 substrates also in solution phase.

description: The study of avalanche events is particularly important to assess and predict the degree of risk involved in a given area and time. In this work we consider an alternative methodology based on a space-time point process where the intensity function indicates the limiting expected rate of occurrence of snow avalanches occurring on day t at location (x, y), conditioned on the historical information available prior to time t . The model depends also on some environmental variables (degree of slope, exposure, altitude, etc.) which may be considered as covariates. In order to show the spatio temporalmodeling of the avalanche hazardwe consider the application to the digitalized Avalanche Database of the Trentino region, Italy.

description: The previous number of BDC once again dealt with the circular economy model already discussed during the last years, starting from the Japanese experience (BDC 2013, vol.13, no.1) as well as with the circular city model that has been defined as physical-spatial-territorial transposition of the first circular economy model.


It should be noted that both these organizational models correspond to a specific historical-cultural landscape: they shape/re-shape the landscape. But the issue of the “active” role of cultural heritage/landscape in promoting the circular model has not been introduced yet.


With the HORIZON 2020 “CLIC” project, funded by the European Commission (for around 5 million euros), cultural heritage/landscape has been explicitly considered as a generator of resilience, sustainability and inclusion and thus incorporated in the circular city model. The overarching goal of CLIC trans-disciplinary research project is to identify evaluation tools to test, implement, validate and share innovative “circular” financing, business and governance models for systemic adaptive reuse of cultural heritage and landscape, demonstrating the economic, social, environmental convenience, in terms of economic, cultural and environmental wealth.

description: Eine diabetische Stoffwechselstörung in der Frühschwangerschaft ist die Ursache für Frühaborte und Fehlbildungen und ein erhöhtes Risiko des Kindes im Erwachsenenalter selbst an Diabetes mellitus (D.m.) zu erkranken. Um die ungeklärten molekularen Ursachen diabetogener Embryopathien zu untersuchen, wurde im Rahmen dieser Arbeit ein diabetisches Tiermodell (Kaninchen) zur Aufklärung des Einflusses eines maternalen D.m. auf die Embryogenese etabliert. Die wichtigsten Erkenntnisse dieser Arbeit sind: Ein maternaler D.m. stört die Eizellreifung, den embryonalen Metabolismus und die Entwicklung ab der Gastrulation. Insulin-induzierte Differenzierungsprozesse werden bei der Blastozyste über das wnt/ß-Catenin-System vermittelt. Durch einen Insulinmangel verzögert sich die Induktion mesodermspezifischer Transkriptionsfaktoren. In der Arbeit wird gezeigt, dass das Insulin/IGF-System für die Gastrulation essentiell ist und ein Insulinmangel beim Embryo zu Entwicklungsstörungen führt.
description: A diabetic disorder in early pregnancy is the cause of early abortions, pregnancy complications and birth defects of the child. After birth the risk to develop diseases of the metabolic syndrome in adulthood is significantly increased. Using a pregnant rabbit model, we induced an insulin dependent diabetes mellitus. The main findings of this work are: Maternal diabetes interferes with oocyte maturation, embryonic metabolism and developmental processes from the gastrulation onwards. Insulin-induced differentiation processes are mediated via the wnt/ß-catenin signaling system. Due to the lack of insulin, the induction of mesoderm-specific transcription factors is delayed. For mammalian gastrulation the insulin/IGF-system is essential. A lack of insulin in the embryo leads to serious developmental disorders as early as during the preimplantation period.

description: Based on a longitudinal case study, we aim to understand how serial entrepreneurs can foster the development of born-global ventures. We consider a born-global start-up as the final stage of the learning process for a serial entrepreneur, advancing propositions regarding the importance of prior entrepreneurial experience for born-global venture creation and growth. We suggest that the serial entrepreneur’s previous entrepreneurial experiences could substitute for the lack of knowledge, opportunity recognition and social networks of a born-global start-up. Thus, we recognize the necessity of a shift in the unit of analysis, from born-global start-up to a global serial entrepreneur, suggesting to follow a dynamic approach when the born-global start-up issue is discussed.

description: Many organizations rely on the skills of innovative individuals to create value, including academic and government institutions, think tanks, and knowledge-based firms. Roughly speaking, workers in these fields can be divided into two categories: specialists, who have a deep knowledge of a single area, and generalists, who have knowledge in a wide variety of areas. In this paper, I examine an individual's choice to be a specialist or generalist. My model addresses two questions: first, under what conditions does it make sense for an individual to acquire skills in multiple areas, and second, are the decisions made by individuals optimal from an organizational perspective? I find that when problems are single-dimensional, and disciplinary boundaries are open, all workers will specialize. However, when there are barriers to working on problems in other fields, then there is a tradeoff between the depth of the specialist and the wider scope of problems the generalist has available. When problems are simple, having a wide variety of problems makes it is rational to be a generalist. As these problems become more difficult, though, depth wins out over scope, and workers again tend to specialize. However, that decision is not necessarily socially optimal--on a societal level, we would prefer that some workers remain generalists.

description: Petunia hybrida ist durch die Nutzung als Zierpflanze von wirtschaftlicher Bedeutung und kann sowohl generativ als auch vegetativ vermehrt werden. Für die vegetative Vermehrung über Stecklinge werden Seitentriebe von der Mutterpflanze abgetrennt und in einem entsprechenden Substrat bewurzelt. Für die Regeneration vollständiger Pflanzen ist die Ausbildung eines funktionsfähigen Wurzelsystems (Adventivwurzeln) essentiell. Die Entwicklung der Adventivwurzeln ist neben exogenen auch von endogenen Faktoren, wie den Phytohormonen Auxin und Ethylen beeinflusst. In Bezug auf eine Funktion der Phytohormonklasse Jasmonate (Jasmonsäure [JA] und ihre Derivate)in diesem pflanzlichen Entwicklungsprozess ist bisher wenig bekannt. Im Rahmen dieser Arbeit wurde mit Hilfe von Applikationsexperimenten gezeigt, dass exogene Jasmonate die Regeneration der Adventivwurzeln an Petunia−Stecklingen inhibieren. Diese Wirkung konnte jedoch durch eine gleichzeitige Gabe von Auxin oder Ethylen abgeschwächt werden. Um wiederum den endogenen Gehalt der Jasmonate in Petunia-Stecklingen zu verändern, wurden die Allenoxid-Cyclase, ein Enzym der JA-Biosynthese, genutzt, um über einen RNAi-Ansatz die Kapazität der JA-Biosynthese in transgenen Pflanzen zu reduzieren. Aber auch dieses Zuwenig von Jasmonaten beeinflusst die Adventivwurzelentwicklung negativ und resultierte in der Bildung von weniger Adventivwurzeln. Dies ergab sich wahrscheinlich aus einem zeitlich verzögerten Beginn der Wurzelregeneration in den Stecklingen der RNAi-Pflanzen, der sich in ersten Analysen nicht auf veränderte Auxin- und Ethylengehalte zurückführen ließ.

description: In this contribution, we wish to explore the relationships between rivalry and geographical proximity at the very level of contacts between individual firms. In particular, we wish to highlight the influence of geographical proximity on rival identification, on the comparison of their knowledge, and on the consequent elaboration of a strategy.
In order to reproduce the interactions between firms, we made use of an agent-based model (ABM) where the strategic choices of rival firms are derived from general assumptions on competitive behavior and learning processes. Aim of the model is to investigate the co-evolution of firms’ knowledge, strategies and performances.

description: Complementation and determinization are two fundamental notions in automata theory. The close relationship between the two has been well observed in the literature. In the case of nondeterministic finite automata on finite words (NFA), complementation and determinization have the same state complexity, namely Theta(2^n) where n is the state size. The same similarity between determinization and complementation was found for Buchi automata, where both operations were shown to have 2^Θ(n lg n) state complexity. An intriguing question is whether there exists a type of omega-automata whose determinization is considerably harder than its complementation. In this paper, we show that for all common types of omega-automata, the determinization problem has the same state complexity as the corresponding complementation problem at the granularity of 2^Θ(.).

Pilzextrakte mit androgener oder antiandrogener Aktivität zu identifizieren wurde eine Screeningroute etabliert. Diese bestand aus einem Zellproliferationsassay mit LNCaP- und PC-3-Zellen, einem AR-Bindungsassay und einem Genexpressionsassay unter Verwendung von VCaP- und LNCaP-Zellen. 147 Verbindungen und 186 Fraktionen aus 23 Organismen wurden getestet. Die identifizierten sechs potentesten AR-Binder wurden auf ihre Bindungsaffinität an den anderen Steroidhormonrezeptoren getestet. Der stärkste AR-Binder (Ki = 10.8 nM) wirkt agonistisch und weist eine nichtspezifische AR-Bindung auf. Von den aktiven Fraktionen wurden die Cibotium barometz-Fraktionen für weiterführende Untersuchungen ausgewählt. Durch Genexpressionsanalyse konnte ein antiandrogenes Verhalten über eine Erniedrigung des PSA- und AR-mRNA-Spiegels gezeigt werden.

Driver head pose sensing using a capacitive array and a time-of-flight camera
Creators: name: Ziraknejad, Nima
Publisher: name: University of British Columbia
Year: 2014

description: Improving the safety of vehicle occupants has gained increasing attention among automotive manufacturers and researchers over the past three decades. There is increased potential for injury mitigation techniques to be applied more effectively to vehicle safety systems if the pose (i.e. the position and orientation) of the driver’s head with respect to the Head Restraint (HR) device can be provided to such safety systems in real-time during vehicle operation. This information is valuable to a range of systems including: adaptive HR positioning for whiplash injury mitigation, advanced driver assistance, driver inattention and fatigue detection, and other possible applications. This thesis proposes, implements, and evaluates a new integrated hybrid sensing approach to providing the driver’s head pose both accurately and in real-time by employing two different sensing subsystems inside the vehicle: 1) a novel capacitive proximity sensing array, and 2) an Illumination-Compensated (IC) Time-of-Flight (ToF) range imaging camera. Firstly, for position sensing, a capacitive proximity sensing electrode and array were developed through electrostatic field analysis and then optimized using numerical modeling studies. Experiments (including environmental testing) using a full system prototype of the position sensing array were performed for numerical modeling validation and accuracy testing. Secondly, since orientation sensing (found to be inaccurate with capacitive sensing alone), this work demonstrated how a ToF camera can be utilized to obtain an accurate measurement of the driver’s head pose using a novel light IC technique. A laboratory testbed was also built to accommodate the aforementioned hybrid system. The capacitive array was incorporated inside the frontal compartment of a customized HR device as part of the testbed, and the ToF camera was installed in front of the driver. Laboratory experiments have demonstrated that the head position can be estimated with a mean Euclidean distance error of 0.33 cm and a Mean Absolute Error in orientation of 3.45° and 1.61° for head yaw and pitch angles, respectively. The thesis also contains a comprehensive introduction to the problem, review of relevant current literature in the area, comparison with the findings of previous related investigations, discussion of the implications of the work and suggestions for future work.

description: This paper deals with minimax rates of convergence for estimation of density functions on the real line. The densities are assumed to be location mixtures of normals, a global regularity requirement that creates subtle difficulties for the application of standard minimax lower bound methods. Using novel Fourier and Hermite polynomial techniques, we determine the minimax optimal rate - slightly larger than the parametric rate - under squared error loss. For Hellinger loss, we provide a minimax lower bound using ideas modified from the squared error loss case.

description: Reliable encoding of information in quantum systems is crucial to all approaches to quantum information processing or communication. This applies in particular to photons used in linear optics quantum computing (LOQC), which is scalable provided a deterministic single-photon emission and preparation is available. Here, we show that narrowband photons deterministically emitted from an atom-cavity system fulfill these requirements. Within their 500 ns coherence time, we demonstrate a subdivision into d time bins of various amplitudes and phases, which we use for encoding arbitrary qu-d-its. The latter is done deterministically with a fidelity >95% for qubits, verified using a newly developed time-resolved quantum-homodyne method.

description: Das metabolische Mikromilieu von Tumoren unterscheidet sich deutlich von Normalgeweben und beeinflusst das maligne Potenzial und die Effektivität von Tumortherapien. Eine charakteristische Eigenschaft ist das Auftreten einer Azidose als Ausdruck des glykolytischen Stoffwechsels. Das Ziel der vorliegenden Arbeit war es, den Einfluss der extrazellulären Azidose auf zelluläre Signalwege zu untersuchen. Zudem wurden pH-abhängige Effekte auf das Zellüberleben, den Metabolismus sowie die Tumorzellmotilität und -invasivität analysiert. Azidose führte zu einer Aktivierung der MAP-Kinasen ERK1/2 und p38 vermittelt durch reaktive Sauerstoffspezies. Desweiteren war die Migration der Zellen gesteigert, jedoch unabhängig von ERK1/2 und p38. Aus diesen Ergebnissen zum Einfluss einer Azidose auf die Signaltransduktion und Motilität können sich neue Ansätze für eine individualisierte Tumortherapie ergeben.
description: The metabolic microenvironment of tumors differs profoundly from normal tissues and affects both malignant potential and efficacy of tumor treatments. A commonly found characteristic is acidosis reflecting the glycolytic metabolism. The aim of the present work was to study the impact of extracellular acidosis on cell signaling. Additionally, pH-dependent changes of cell survival, metabolism as well as tumor cell motility and invasiveness were analyzed. Acidosis led to an activation of the MAP kinases ERK1/2 and p38 which depended on reactive oxygen species. Furthermore, tumor cell migration was increased, but independently of ERK1/2 and p38. From these results on the impact of acidosis on cellular signaling and cell motility new approaches for an individualized tumor treatment can be developed.

description: L’obiettivo principale del presente lavoro è studiare le determinanti della domanda dei servizi di corporate banking da parte delle imprese italiane di piccole e medie dimensioni (PMI), analizzando in particolare la loro propensione all’utilizzo degli strumenti di finanziamento alternativi al debito bancario. La letteratura finanziaria si è spesso concentrata sul lato dell’offerta dei servizi di corporate banking, mentre scarsa attenzione è stata rivolta al lato della domanda di tali servizi da parte delle PMI, soprattutto per quanto riguarda i servizi più innovativi di corporate banking. Il presente lavoro si propone pertanto l’obiettivo di colmare il suddetto gap, valutando all’interno dei servizi per le imprese offerti dagli intermediari finanziari (bancari e non) quali sono le principali fonti di finanziamento generalmente utilizzate dalle imprese italiane, con particolare riferimento alle imprese di piccole-medie dimensioni.

description: Die intraaortale Ballongegenpulsation (IABP) ist aktuell bei Patienten im infarktbedingten kardiogenen Schock (IkS) das am häufigsten angewandte mechanische Unterstützungssystem. Trotz eingeschränkter Evidenz zur therapeutischen Überlegenheit der IABP bei Patienten mit IkS gibt es eine Klasse-I-Empfehlung in den amerikanischen und europäischen Leitlinien. Ziel dieser systematischen Übersichtsarbeit war die Beurteilung von Effektivität und Sicherheit der IABP bei Patienten mit IkS bezugnehmend auf Mortalität. Hierzu wurden per elektronischer Datenbankrecherche insgesamt 6 randomisiert klinische Studien und ein laufendes Projekt ermittelt. Hier wurde die IABP-Therapie einer Standardbehandlung ohne IABP oder einer Therapie mit alternativen Herzunterstützungssytemen gegenübergestellt. Die Ergebnisse der Metaanalyse von insgesamt 190 Patienten mit IkS zeigen trotz nachweislicher Verbesserung der Hämodynamik bei IABP-Einsatz für keine der Behandlungsgruppen einen Überlebensvorteil auf.
description: Intra-aortic balloon pump (IABP) is currently the most commonly used mechanical assist device for patients with cardiogenic shock (CS) due to acute myocardial infarction (AMI). Although there is only limited evidence by randomised controlled trials, the current American and European guidelines strongly recommend the use of IABP in patients with infarction-related CS. To determine the effect of IABP versus non-IABP or other assist devices in terms of efficacy and safety in patients with AMI complicated by CS, searches of medical literature databases, registers of ongoing trials were conducted. 6 eligible and one ongoing studies were identified. Data from a total of 190 patients with acute myocardial infarction and CS were included in the meta-analysis of the systematic review. Available results suggests that IABP may have a beneficial effect on the haemodynamics, however there is no convincing randomised data to support the use of IABP in infarct related CS.

description: Derived A-infinity algebras were developed recently by Sagave. Their advantage over classical A-infinity algebras is that no projectivity assumptions are needed to study minimal models of differential graded algebras. We explain how derived A-infinity algebras can be viewed as algebras over an operad. More specifically, we describe how this operad arises as a resolution of the operad dAs encoding bidgas. This generalises the established result describing the operad A-infinity as a resolution of the operad As encoding associative algebras. We further show Sagave's definition of morphisms agrees with the infinity-morphisms of dA-infinity algebras arising from operadic machinery. We also study the operadic homology of derived A-infinity algebras.

Predicting affect in an Intelligent Tutoring System

Publisher: name: University of British Columbia

description: In this thesis we investigate the usefulness of various data sources for predicting emotions relevant to learning, specifically boredom and curiosity. The data was collected during a study with MetaTutor, an intelligent tutoring system (ITS) designed to promote the use of self-regulated learning strategies. We used a variety of machine learning and feature selection techniques to predict students‘ self-reported emotions from eye tracking data, distance from the screen, electrodermal activity, and an ensemble of all three sources. We also examine the optimal amount of interaction time needed to make predictions using each source, as well as which gaze features are most predictive of each emotion. The findings provide insight into how to detect when students disengage from MetaTutor.

description: In this paper, collocation methods are used for detecting blow-up solutions of nonlinear homogeneous Volterra-Hammerstein integral equations. To do this, we introduce the concept of "blow-up collocation solution" and analyze numerically some blow-up time estimates using collocation methods in particular examples where previous results about existence and uniqueness can be applied. Finally, we discuss the relationships between necessary conditions for blow-up of collocation solutions and exact solutions.

description: Many observables in QCD rely upon the resummation of perturbation theory to retain predictive power. Resummation follows after one factorizes the cross section into the rele- vant modes. The class of observables which are sensitive to soft recoil effects are particularly challenging to factorize and resum since they involve rapidity logarithms. In this paper we will present a formalism which allows one to factorize and resum the perturbative series for such observables in a systematic fashion through the notion of a "rapidity renormalization group". That is, a Collin-Soper like equation is realized as a renormalization group equation, but has a more universal applicability to observables beyond the traditional transverse momentum dependent parton distribution functions (TMDPDFs) and the Sudakov form factor. This formalism has the feature that it allows one to track the (non-standard) scheme dependence which is inherent in any scenario where one performs a resummation of rapidity divergences. We present a pedagogical introduction to the formalism by applying it to the well-known massive Sudakov form factor. The formalism is then used to study observables of current interest. A factorization theorem for the transverse momentum distribution of Higgs production is presented along with the result for the resummed cross section at NLL. Our formalism allows one to define gauge invariant TMDPDFs which are independent of both the hard scattering amplitude and the soft function, i.e. they are uni- versal. We present details of the factorization and resummation of the jet broadening cross section including a renormalization in pT space. We furthermore show how to regulate and renormalize exclusive processes which are plagued by endpoint singularities in such a way as to allow for a consistent resummation.

description: Seroepidemiologische Studien geben Aufschluss über den Bevölkerungsanteil, der bereits eine SARS-CoV-2-Infektion durchgemacht hat und schließen dabei auch nicht erkannte Infektionen (Untererfassung) ein¬. Die hier zusammengestellten Ergebnisse zur Sero¬prävalenz von SARS-CoV-2 basieren auf Zufalls¬stichproben der erwachsenen Allgemeinbevölke¬rung in Deutschland und liegen für verschiedene Zeiträume der Pandemie aus 20 Studien vor. Die geringe und im Pandemieverlauf deutlich ge¬sunkene Untererfassung in Deutschland zeigt, dass SARS-CoV-2-Infektionen gut im Meldesystem abgebildet werden.

description: Für verschiedenste Untersuchungen an dentalen Hartgeweben werden extrahierte humane Zähne verwendet. Da sich diese Untersuchungen meist über längere Zeiträume erstrecken, stellt sich die Frage nach einer günstigen Form der Lagerung. Innerhalb dieser Studie wurde der Einfluss von physiologischer Natriumchloridlösung, Kalziumchloridlösung, Hanks buffered salt solution, 0,1%iger Thymollösung und von pH-neutralem Speichel nach Fusayama auf die mechanischen Eigenschaften Härte und Elastizitätsmodul sowie die Oberflächenbeschaffenheit von Schmelz und Dentin über einen Zeitraum von 50 Tagen untersucht. Es konnte gezeigt werden, dass Natriumchlorid und der Speichel nach Fusayama als Lagermedium hervorragend geeignet sind. Hanks buffered salt solution ist nur bedingt für die Lagerung dentaler Hartgewebe geeignet. Kalziumchloridlösung und 0,1%ige Thymollösung sind für die Lagerung von dentalen Hartgeweben nicht geeignet.
description: Extracted human teeth are used for all sorts of studies on dental hard tissues. The prolonged nature of these studies begs the question of the most suitable storage medium. Over a period of 50 days, this study examined the effects physiological sodium chloride solution, calcium chloride solution, Hank’s buffered salt solution, 0.1% thymol and pH-neutral Fusayama saliva have on the mechanical properties of hardness and elasticity modulus as well as the surface quality of enamel and dentine. The main result is that Sodium chloride and pH-neutral Fusayama saliva were found to be an outstanding storage media. Accordingly, the suitability of Hanks’ buffered salt solution for storing dental hard tissue is limited. We therefore conclude that calcium chloride solution and 0,1% thymol solution are unsuitable for storing dental hard tissues.

description: Let $S$ be a set of transpositions that generates the symmetric group $S_n$, where $n \ge 3$. The transposition graph $T(S)$ is defined to be the graph with vertex set $\{1,\ldots,n\}$ and with vertices $i$ and $j$ being adjacent in $T(S)$ whenever $(i,j) \in S$. We prove that if the girth of the transposition graph $T(S)$ is at least 5, then the automorphism group of the Cayley graph $\Cay(S_n,S)$ is the semidirect product $R(S_n) \rtimes \Aut(S_n,S)$, where $\Aut(S_n,S)$ is the set of automorphisms of $S_n$ that fixes $S$. This strengthens a result of Feng on transposition graphs that are trees. We also prove that if the transposition graph $T(S)$ is a 4-cycle, then the set of automorphisms of the Cayley graph $\Cay(S_4,S)$ that fixes a vertex and each of its neighbors is isomorphic to the Klein 4-group and hence is nontrivial. We thus identify the existence of 4-cycles in the transposition graph as being an important factor in causing a potentially larger automorphism group of the Cayley graph.

description: Die Diphosphataktivierung ist ein Prozess bei dem im Zuge der Abspaltung eines Diphosphatrestes von einem organischen Substrat dieses aktiviert und somit für nukleophile Angriffe zugänglich wird. Die Bedeutung und Diversität von derart biosynthetisierten Enzymprodukten ist dabei enorm: Sie reicht von ätherischen Ölen über Hormone und Reservestoffe bis hin zu pharmazeutisch interessanten Verbindungen, wie Antibiotika oder Chemotherapeutika. Systematische Analysen von über 400 Diphosphatbindestellen sollen – begleitet durch quantenchemische Berechnungen – zur Aufklärung aktivierungsrelevanter Faktoren beitragen. Dabei wird insbesondere auf die Diphosphaterkennung und -konformation in der Bindetasche sowie auf kinetische Aspekte des Aktivierungsprozesses eingegangen. Die gewonnenen Erkenntnisse können in Zukunft helfen, synthetisch hergestellte, diphosphat-aktivierende Verbindungen zu optimieren und damit den heute z.T. noch sehr schwierigen Zugang zu pharmazeutisch relevanten Substanzen erleichtern.
