title: Identification of the Driving Dynamics of a Skid-Steered Mobile Robot Based on Geodetic Measurements

description: The driving dynamics of skid-steered vehicles are difficult to model due to their inherent need for loss of traction for curvilinear motion, which leads to complex wheel-ground interactions. However, such vehicles represent well suited platforms for automated robots with their robust, cost-effective, low maintenance construction and their great off-road performance. One usecase of them is mobile mapping. Such systems can greatly benefit from precise driving dynamic models for pose estimation for both georeferencing measurements and navigation as well as for system control using model predictive control methods.System identification is a field of applied mathematics for estimating models of dynamical systems based on measured input and output data of the system. The SINDY (Sparse Identification of Nonlinear DYnamics) algorithm is a method that utilizes sparse regression to identify interpretable, parsimonious models in state-space representation, that balance model performance with complexity.In this thesis the suitability of the SINDY algorithm to conduct system dentification for the driving dynamics of the Clearpath Husky A200 based on geodetic measurements was ascertained. The Husky A200 is a medium sized robot for research and prototyping and represents an example of skid-steered unmanned ground vehicle (UGV) well suited for tasks such as mobile mapping. A measurement setup around two laser trackers for collecting the necessary data was created, addressing the challenges of time synchronisation of the different system components and maintaining an uninterrupted line of sight between the laser trackers and their target prism during driving operations.A preprocessing pipeline to calculate the system identification input data was established, accomplishing time synchronisation, pose calculation and interpolation as well as state vector calculation and transformation. The system identification was successfully conducted, utilizing the integral notation of SINDY and employing an extensive hyperparameter tuning. The point position estimation uncertainty of the best performing model was 14 cm after a 5 second integration period, with the heading estimation uncertainty being 4.7◦. These results demonstrate the suitability of identified systems for example for certain applications of state estimation. Potential shortcomings and areas for improvements of the presented measurement setup and methodology were identified and discussed.
Perfluorinated compounds in landfill leachate from discarded carpets

description: Perfluorinated compounds (PFCs) are a class of anthropogenic chemicals incorporated over six decades into a wide range of industrial and consumer-use products including surface treatments for carpets and textiles, paper and packaging, non-stick cookware, firefighting foams and insecticides. The extremely strong carbon-fluorine bond, "the strongest in organic chemistry", makes them thermally and chemically stable, and resistant to degradation. Several studies on toxicology of PFCs demonstrate negative health effects of these compounds. Some PFCs were added to the Stockholm convention on Persistent Organic Pollutants (POPs) in 2009, due to their persistence, toxicity, and widespread occurrence in the environment. Stain-resistant carpets comprise a major part of global historical PFC production and use. Landfills are a major source of PFC emissions to the environment as final destinations for discarded consumer articles, including carpets. This thesis explores how various PFCs leach from carpets to landfill leachate, and how factors like temperature, pH and contacting efficiency affect the transfer of PFCs into aqueous media. Experiments were conducted in which a number of carpets manufactured in ~2000 to 2005 were contacted with landfill leachate and distilled water. Transfer of different PFCs into the aqueous phase increased with contacting time, with differences between 1 and 24 h much greater than between 24 and 168 h. A temperature increase from 5 to 35oC resulted in a significant increase in PFC leaching. Increasing the pH from 5 to 8 resulted in an increase followed by a decrease in leaching of most PFCs. The overall leaching rates of PFCAs into distilled water were somewhat greater than into landfill leachate. The majority of PFC exchange between carpets and leachate was more dependent on some factor (e.g. adsorption or desorption) rather than external mass transfer.

description: We investigate using Amazon Mechanical Turk (AMT) for building a low-level description corpus and populating VigNet, a comprehensive semantic resource that we will use in a text-to-scene generation system. To depict a picture of a location, VigNet should contain the knowledge about the typical objects in that location and the arrangements of those objects. Such information is mostly common-sense knowledge that is taken for granted by human beings and is not stated in existing lexical resources and in text corpora. In this paper we focus on collecting objects of locations using AMT. Our results show that it is a promising approach.

description: We simulate the homogeneous nucleation of ice from supercooled liquid water at 220 K in the isobaric-isothermal ensemble using the MW monatomic water potential. Monte Carlo simulations using umbrella sampling are performed in order to determine the nucleation free energy barrier. We find the Gibbs energy profile to be relatively consistent with that predicted by classical nucleation theory; the free energy barrier to nucleation was determined to be ~18 kT and the critical nucleus comprised ~85 ice particles. Growth from the supercooled liquid gives clusters that are predominantly cubic, whilst starting with a pre-formed subcritical nucleus of cubic or hexagonal ice results in the growth of predominantly that phase of ice only.

description: Ziel dieser Arbeit ist die Untersuchung von zwei verschiedenen Messverfahren basierend auf einer elektrischen Leistungsmessung und einer photometrischen Emissionsmessung zur Sicherstellung der elektromagnetischen Verträglichkeit von elektrischen Zündmitteln (EED) und elektrischen Zündkreisen (ZKE) bei gestrahlten impulsförmigen Störsignalen, wie sie z.B. von High-Power-Microwave (HPM)-, Damped-Sinusoidal (DS)- oder Ultra-Wide-Band (UWB)-Quellen generiert werden können. Aus dem zeitlichen Verlauf der elektrischen Messgrößen kann auf die vom EED-Brückendraht absorbierte Energie und die damit einhergehende Temperaturerhöhung und damit auf die Einhaltung bzw. Nichteinhaltung der geforderten Sicherheitsabstände geschlossen werden. Für den messtechnischen Vergleich wurde ein EED-Testsystem aufgebaut, in dem alle erforderlichen Sensoren integriert wurden. Die Arbeit diskutiert die gemessenen Störsicherheitsabstände für einige ausgewählte Leitungskonfigurationen aus durchgeführten Bestrahlungsuntersuchungen mit einer breitbandigen DS-Quelle. Eine Validierung der experimentellen Ergebnisse erfolgt durch Einkopplungs-, Impedanz- und Temperaturmodelle. Diese sind überwiegend in Form einer SPICE-Netzwerkstruktur angegeben, mit dem Vorteil, dass sie in einer einheitlichen numerischen Simulationsumgebung übersichtlich zusammengeschaltet werden können.
description: Goal of this work is the investigation of two different measurement techniques based on an electrical power measurement and a photometric radiation measurement to guarantee the electromagnetic compatibility of electrical explosive devices (EED) with connected firing circuit in the presence of radiated pulsed disturbances which may be generated by High-Power-Microwaves (HPM)-, Damped-Sinusoidal (DS),- or Ultra-Wide-Band (UWB) sources. The measurement gives information about absorbed EED bridgewire energy and corresponding temperature increase in order to verify the compliance or non-compliance with EED safety margin regulations. Both measurement techniques have been compared by use of an EED test system in which all sensors have been integrated. The work discusses the measured safety margins at wideband DS-irradiation for some selected firing line configurations. The experimental results are validated by coupling-, impedance- and temperature models. They are mostly given in a SPICE network structure with the advantage that they can easily be combined in a unique simulation environment.

description: Narratives on the goal and purpose of the integration process play a key role in the legitimisation of the European Union. This working paper critically analyses four narratives that stand out in the public debate: the peace narrative, according to which the EU primarily serves to avoid conflicts among its member states; the prosperity narrative, according to which the EU increases the economic well-being of its member states; the self-assertion narrative, which sees European integration as necessary for member states to be able to play an active role on the world stage; and the cosmopolitan-democratic narrative, according to which European integration serves the double purpose of promoting individual freedom and collective democratic self-government beyond the nation state. It is argued that this last narrative offers the most comprehensive and convincing justification for supranational integration.

On black hole thermalization, D0 brane dynamics, and emergent spacetime

Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)

description: When matter falls past the horizon of a large black hole, the expectation from string theory is that the configuration thermalizes and the information in the probe is rather quickly scrambled away. The traditional view of a classical unique spacetime near a black hole horizon conflicts with this picture. The question then arises as to what spacetime does the probe actually see as it crosses a horizon, and how does the background geometry imprint its signature onto the thermal properties of the probe. In this work, we explore these questions through an extensive series of numerical simulations of D0 branes. We determine that the D0 branes quickly settle into an incompressible symmetric state -- thermalized within a few oscillations through a process driven entirely by internal non-linear dynamics. Surprisingly, thermal background fluctuations play no role in this mechanism. Signatures of the background fields in this thermal state arise either through fluxes, i.e. black hole hair; or if the probe expands to the size of the horizon -- which we see evidence of. We determine simple scaling relations for the D0 branes' equilibrium size, time to thermalize, lifetime, and temperature in terms of their number, initial energy, and the background fields. Our results are consistent with the conjecture that black holes are the fastest scramblers as seen by Matrix theory.

description: Additional file 4: Figure S4. Anterograde transport of secretory cargo proteins is not significantly altered in ACBD3-depleted cells. In order to investigate whether ACBD3 depletion might have affected anterograde transport between the ER and the Golgi, secretion of three different cargo proteins was tested, including TfR-RM4-SNAP (A), VSVG-tsO45-GFP (B), endogenous MMP-2 (C) and YFP-GL-GPI (D). (A-B) Briefly, plasmids encoding the indicated constructs were transiently transfected into control cells or ACBD3-depleted HeLa cells for 18 hours. Cells were then treated with cycloheximide for 2 hours, prior to induction of synchronized protein secretion by shifting temperature from 40.5 to 32 °C. (VSVG-tsO45-GFP) or treatment with D/D solubilizer drug (TfR-FM4-SNAP) for the indicated times. At the indicated timepoints, the cells were placed on ice and subjected to surface biotinylation using sulfo-NHS-LC-biotin for 30 min. The cells were then lysed, subjected to pulldown with streptavidin-agarose and analyzed by western blot. (C) For MMP2 measurement, the conditioned media from control HT1080 or ACBD3-KO HT1080 cells were collected after 18 hours incubation and added to Total MMP2 Quantikine ELISA kit for quantification, as described in the methods. (D) After 18 hrs transfection of YFP-GL-GPI, HeLa WT and ACBD3-KO cells were stained for indicated antibodies and then examined by confocal microscopy. Line profiles through regions of interest were analyzed by Fiji. (Scale bars = 10 μm) (E-F) HeLa-WT or HeLa-ACBD3-KO cells were transfected with sialyltransferase-RFP (ST-RFP, a Golgi marker) and His-tagged Shiga toxin B fragment (2.5 mg/ml final concentration in DMEM+1�S) was added to cells for 45min at 4°C. After the withdrawal of unbound toxin by washing for three times in ice-cold PBS, cells were incubated with DMEM+10�S at 37°C for indicated time points. Then cells were stained using anti-His-tag and anti-calnexin (as an ER marker) antibodies. The results show that plasma membrane-to-Golgi transport of His-tagged Shiga toxin B fragment is not altered in ACBD3-KO cells, while the Golgi-to-ER transport of His-tagged Shiga toxin B fragment is accelerated in ACBD3-KO cells. Scale bars = 10 μm.
Bulk viscosity and the phase transition of the linear sigma model

description: In this work we deal with the critical behavior of the bulk viscosity in the linear sigma model (LSM) as an example of a system which can be treated by using different techniques. Starting from the Boltzmann-Uehling-Uhlenbeck equation we compute the bulk viscosity over entropy density of the LSM in the large-N limit. We search for a possible maximum of the bulk viscosity over entropy density at the critical temperature of the chiral phase transition. The information about this critical temperature, as well as the effective masses, is obtained from the effective potential. We find that the expected maximum (as a measure of the conformality loss) is absent in the large N in agreement with other models in the same limit. However, this maximum appears when, instead of the large-N limit, the Hartree approximation within the Cornwall-Jackiw-Tomboulis (CJT) formalism is used. Nevertheless, this last approach to the LSM does not give rise to the Goldstone theorem and also predicts a first order phase transition instead of the expected second order one. Therefore both, the large-N limit and the CJT-Hartree approximations, should be considered as complementary for the study of the critical behavior of the bulk viscosity in the LSM.

description: Following previous work (JCP 134, 201103 (2011)), the replica exchange Monte Carlo technique is used to produce the equation of state of hard 1:5 aspect-ratio oblate ellipsoids for a wide density range. Here, in addition to the analytical approximation of the overlap distance given by Berne and Pechukas (BP) and the exact numerical solution of Perram and Wertheim, we tested a simple modification of the original BP approximation (MBP) which corrects the known T-shape mismatch of BP for all aspect-ratios. We found that the MBP equation of state shows a very good quantitative agreement with the exact solution. The MBP analytical expression allowed us to study size effects on the previously reported results. For the thermodynamic limit, we estimated the exact 1:5 hard ellipsoid isotropic-nematic transition at the volume fraction 0.343(3), and the nematic-solid transition in the volume fraction interval 0.592(6)-0.634(8).

description: The increasing quantity of video material available on line requires improved methods to help users navigate such data, among which are topic tracking techniques. The goal of this paper is to show that prosodic information can improve an ASRbased topic tracking system for TV Broadcast News. To this end, two kinds of prosodic information—extracted with and without a learning phase—are integrated in the system. This integration shows significant improvements in the F1-measure, by 13 and 8 points for the two techniques compared with the baseline system.

description: The enthymeme has been a central component of rhetorical proof from early Greek philosophy to modern rhetorical theory. In this conference presentation, I examine how Cicero and Quintilian, two canonical sources of rhetorical thought from Roman antiquity, conceive of this critical term. I show first that Cicero understood this foundational component of ancient rhetorical theory as a component of rational Stoic logic, and second that according to Quintilian, an enthymeme, even if it is defined in strictly rational terms, nevertheless incorporates ethical and emotional components that are unavoidable in the field of rhetorical persuasion. Or in the terms of Aristotelian rhetoric, Cicero's enthymeme incorporates only logos, only the logical component of proof. Quintilian's, however, incorporates all three elements: logos, ethos, and pathos.

Title: Sustainable behaviour change through community engagement Abstract: Sustainability can be achieved through regenerative engagement with resources. Volunteer researchers are our key resource in promoting behaviour change towards the adoption of open science, and we must work carefully to ensure that these contributors are engaged in a way which is sustainable for our desired outcomes, their careers, and the values of open science and open leadership. In this talk I will outline community engagement models which can be used to support the growth of sustainable open science communities to promote the transfer of knowledge, contribute to internal and external policy, and contribute to the design and testing of infrastructure. I will also highlight the value of a professional community manager and other team infrastructure roles to deliver sustainable and regenerative open science.

description: The radii of giant planets, as measured from transit observations, may vary with wavelength due to Rayleigh scattering or variations in opacity. Such an effect is predicted to be large enough to detect using ground-based observations at multiple wavelengths. We present defocussed photometry of a transit in the HAT-P-5 system, obtained simultaneously through Stromgren u, Gunn g and r, and Johnson I filters. Two more transit events were observed through a Gunn r filter. We detect a substantially larger planetary radius in u, but the effect is greater than predicted using theoretical model atmospheres of gaseous planets. This phenomenon is most likely to be due to systematic errors present in the u-band photometry, stemming from variations in the transparency of Earth's atmosphere at these short wavelengths. We use our data to calculate an improved orbital ephemeris and to refine the measured physical properties of the system. The planet HAT-P-5b has a mass of 1.06 +/- 0.11 +/- 0.01 Mjup and a radius of 1.252 +/- 0.042 +/- 0.008 Rjup (statistical and systematic errors respectively), making it slightly larger than expected according to standard models of coreless gas-giant planets. Its equilibrium temperature of 1517 +/- 29 K is within 60K of that of the extensively-studied planet HD 209458b.

Input is syntactically and semantically processed to identify a set of graphical objects and constraints which are then rendered as a 3D scene. We describe experiments with the system in a summer literacy enrichment program conducted at the Harlem Educational Activities Fund with 6th grade students, in which students using the system had significantly greater improvement in their literary character and story descriptions in pre- and post- test essays compared with a control. Students reported that using the system helped them imagine the events in the stories they were reading better. We also observed that social interaction engendered by this process was a strong motivator.

description: We present derived stellar and disc parameters for a sample of Taurus brown dwarfs both with and without evidence of an associated disc. These parameters have been derived using an online fitting tool (http://bd-server.astro.ex.ac.uk/), which includes a statistically robust derivation of uncertainties, an indication of pa- rameter degeneracies, and a complete treatment of the input photometric and spectroscopic observations. The observations of the Taurus members with indications of disc presence have been fitted using a grid of theoretical models including detailed treatments of physical processes accepted for higher mass stars, such as dust sublimation, and a simple treatment of the accretion flux. This grid of models has been designed to test the validity of the adopted physical mechanisms, but we have also constructed models using parameterisation, for example semi-empirical dust sublimation radii, for users solely interested in parameter derivation and the quality of the fit. The parameters derived for the naked and disc brown dwarf systems are largely consistent with literature observations. However, our inner disc edge locations are consistently closer to the star than previous results and we also derive elevated accretion rates over non-SED based accretion rate derivations. For inner edge locations we attribute these differences to the detailed modelling we have performed of the disc structure, particularly at the crucial inner edge where departures in geometry from the often adopted vertical wall due to dust sublimation (and therefore accretion flux) can compensate for temperature (and therefore distance) changes to the inner edge of the dust disc. In the case of the elevated derived accretion rates, in some cases, this may be caused by the intrinsic stellar luminosities of the targets exceeding that predicted by the isochrones we have adopted.

description: My research project focuses on Gianlorenzo Bernini’s S. Andrea al Quirinale (1658-71), Rome, church of the Jesuit novitiate and largely underwritten by Prince Camillo Pamphili. This is not, however, a monographic study. S. Andrea is a vehicle for assessing fundamental and influential themes in early modern architectural representation as well as challenging several longstanding assumptions in current methodological approaches. The church is a milestone in any history of early modern architecture and a staple on most survey courses of western art. Over the last thirty years scholars have demonstrated that it was not built to an initial, unitary design but is instead the residue of protracted adaptation and revision (Connors, Frommel, Marder, Terhalle); elucidated the mechanisms of patronage; and explained its iconography (Cather, Careri, Levine). Yet, a full and coherent analysis of the intellectual priorities behind its formal choices, general and particular, is lacking. Indeed, as things stand, it is difficult to understand why Bernini himself considered S. Andrea his best work.

description: Recently, Dyachenko & Zakharov (2011) have derived a compact form of the well known Zakharov integro-differential equation for the third order Hamiltonian dynamics of a potential flow of an incompressible, infinitely deep fluid with a free surface. Special traveling wave solutions of this compact equation are numerically constructed using the Petviashvili method. Their stability properties are also investigated. Further, unstable traveling waves with wedge-type singularities, viz. peakons, are numerically discovered. To gain insights into the properties of singular traveling waves, we consider the academic case of a perturbed version of the compact equation, for which analytical peakons with exponential shape are derived. Finally, by means of an accurate Fourier-type spectral scheme it is found that smooth solitary waves appear to collide elastically, suggesting the integrability of the Zakharov equation.

description: The essays in this volume were delivered at the Third Annual Conference of the Sophia Institute in December 2010 at Union Theological Seminary in New York City. The theme of that conference, “Power and Authority in Eastern Christian Experience,” brought forth a diverse group of scholars who contributed their perspectives on the ways the Eastern Orthodox Church, in its broadest sense, has negotiated the notions of power, authority, (dis)obedience, and resistance over time and space. These insightful essays promise to draw the Orthodox world into a dynamic and productive discourse.
Asymmetric Inelastic Inert Doublet Dark Matter from Triplet Scalar Leptogenesis

description: The nature of dark matter (DM) particles and the mechanism that provides their measured relic abundance are currently unknown. In this paper we investigate inert scalar and vector like fermion doublet DM candidates with a charge asymmetry in the dark sector, which is generated by the same mechanism that provides the baryon asymmetry, namely baryogenesis-via-leptogenesis induced by decays of scalar triplets. At the same time the model gives rise to neutrino masses in the ballpark of oscillation experiments via type II seesaw. We discuss possible sources of depletion of asymmetry in the DM and visible sectors and solve the relevant Boltzmann equations for quasi-equilibrium decay of triplet scalars. A Monte-Carlo-Markov-Chain analysis is performed for the whole parameter space. The survival of the asymmetry in the dark sector leads to inelastic scattering off nuclei. We then apply bayesian statistic to infer the model parameters favoured by the current experimental data, in particular the DAMA annual modulation and Xenon100 exclusion limit. The latter strongly disfavours asymmetric scalar doublet DM of mass $\mathcal{O}(\TeV)$ as required by DM-$\bar{\rm DM}$ oscillations, while an asymmetric vector like fermion doublet DM with mass around 100 GeV is a good candidate for DAMA annual modulation yet satisfying the constraints from Xenon100 data.

Monitoring Exceptional Responses in Patients with B-cell Malignancies

description: Response to cancer treatments can be highly variable; with some patients entering durable remissions, and others either failing to respond or relapsing early. Predicting which patients may derive long term responses and enter deep remissions remains a significant challenge. “Exceptional responders”, ie patients with prolonged and deep responses, where the majority fail to respond, represent a group of patients that could help us understand the mechanisms of treatment sensitivity and enable us to study the depth of minimal residual disease (MRD) required to sustain a durable response. I examined two cohorts of “exceptional responders” to two precision medicines to understand the molecular features, that could explain their durable response: a cohort of ten relapsed/refractory (R/R) patients with Mantle Cell Lymphoma (MCL) treated with Bruton’s Tyrosine Kinase (BTK) inhibitors and a small case series of two patients with Chronic Lymphocytic Leukaemia (CLL) treated with a CD52 antibody (alemtuzumab). Molecular features included mutational profiling, IGHV gene rearrangement, copy number variation and for the MCL cases t(11;14)(q13;q32) translocation. Interestingly, all but two MCL patients had truly unmutated IGHV and three patients had TP53 mutations, features otherwise associated with poor outcomes. The depth of response was assessed using patient-specific ddPCR assays or Lymphotrack. In two MCL cases, there was evidence of disease recurrence using ddPCR before clinical and radiological relapse. In a further two MCL cases, MRD remains undetectable. In one CLL patient, still in remission twenty years post-treatment, re-emergence of polyclonal B cells with absence of the original B-cell clone was observed. A MYD88 mutation from original tumour was undetectable by ddPCR. NGS and ddPCR methods may provide precision tools for monitoring exceptional responders and for early prediction of relapse. However, further validation will be required prior to implementation within the clinic.

Ελληνικές ποικιλίες μελιού

description: Η γλυκαντική ουσία, που παράγεται φυσικώς από τις μέλισσες του είδους Apis melifera, ονομάζεται μέλι. Από την αρχαιότητα θεωρούντο «θεόσταλτη» τροφή και μέχρι σήμερα αποτελεί ένα φυσικό γλυκαντικό προϊόν με πολλές ευεργετικές ιδιότητες για τον ανθρώπινο οργανισμό. Οι ελληνικές ποικιλίες μελιού τοποθετούνται στις πιο ποιοτικές και γευστικές ποικιλίες παγκοσμίως, αποτέλεσμα της ιδιαίτερα ανεπτυγμένης μελισσοκομίας στην χώρα μας, αλλά και του σεβασμού που δείχνουν οι μελισσοκόμοι κατά τη διάρκεια της παραγωγής στις μέλισσες. Το μέλι μπορεί και συνεισφέρει σε ζυμώσιμα σάκχαρα στην μπύρα, αλλά επίσης συνεισφέρει σε χαρακτηριστική γεύση και άρωμα από μόνο του. Ζυθοποιοί και καταναλωτές στην Ελλάδα και τον κόσμο θεωρούν το μέλι να είναι υψηλής αξίας πρόσθετο συστατικό σε μία μπύρα και όχι απλά ένα πρόσθετο ζυθοποίησης. Η παρούσα πτυχιακή εργασία ερευνά ελληνικές ποικιλίες μελιού και κατά πόσο μπορεί να παραχθεί μπύρα τύπου «honey ale» με προσθήκη αυτών. Εξετάζεται ποιες ποικιλίες είναι πιο κατάλληλες σε οργανοληπτικό επίπεδο, αλλά και σε ποιο ποσοστό προσθήκης. Εξετάζεται κατά πόσο μπορεί να γίνει διαφοροποίηση του αρώματος και της γεύσης της μπύρας μετά από προσθήκη μελιού. Γίνεται παρακολούθηση της αλκοολικής ζύμωσης, καθώς και αναλύσεις των μελιών και των τελικών προϊόντων. Επίσης, πραγματοποιείται οργανοληπτική αξιολόγηση σε 14 ποικιλίες ελληνικού μελιού με σκοπό την επιλογή των καταλληλότερων για την προσθήκη σε μπύρα. Τέλος, μέσω οργανοληπτικού πάνελ πραγματοποιείται οργανοληπτικός έλεγχος στις πέντε τελικές μπύρες, τεσσάρων εξ’ αυτών με προσθήκη ελληνικών ποικιλιών μελιού. Το αποτέλεσμα της αξιολόγησης έδειξε ότι συγκεκριμένες ποικιλίες μελιού μπορούν να διαφοροποιήσουν το άρωμα και τη γεύση της μπύρας, το σώμα της, το χρώμα και την επίγευσή της. Ορισμένες ποικιλίες αναδεικνύουν ακόμη και τα πρωτογενή τους αρώματα μέσω της μπύρας.

description: Beim klarzelligen Nierenzellkarzinom spielt das Von-Hippel-Lindau-Gen (VHL) eine große Rolle. In der Therapie kommt u.a. der Tyrosinkinaseinhibitor Sunitinib zur Anwendung. In der Niere herrscht eine stark erhöhte Osmolarität, die sich auf die Expression osmoprotektiver Gene auswirkt, welche wiederum von einer Mutation im VHL-Gen beeinflusst werden. In dieser Arbeit wurde der kombinierte Einfluss von Osmolarität und Sunitinib auf verschiedene Zelllinien des Nierenzellkarzinoms untersucht. Es zeigt sich ein Effekt auf Koloniebildung und Proliferation, allerdings wurde ein zusätzlicher Effekt bei einer kombinierten Gabe nicht nachgewiesen. Bei der Zellzyklusanalyse zeigte sich ein Effekt von Sunitinib auf den Zellarrest. Die Hinzunahme eines Histon-Deacetylase-Hemmers zeigte keinen zusätzlichen Nutzen. Daraus lässt sich schließen, dass Zellen des Nierenzellkarzinoms auf eine erhöhte Osmolarität und Sunitinibkonzentration reagieren, aber ein additiver Nutzen nicht besteht.
description: In clear cell renal cell carcinoma the Von-Hippel-Lindau gene (VHL) is of big importance. The tyrosine kinase inhibitor sunitinib is used in the therapy of this carcinoma. There is an elevated osmolarity in the kidney interstitium, which has an impact on the expression of osmolarity-effected genes. These are again affected by a mutation in the VHL gene. I examined the impact of a combined use of osmolarity and sunitinib on several different cell lines of the clear cell renal cell carcinoma. I could show an effect of both sunitinib and high osmolarity in colony forming assays and proliferation assays, however none in case of a combined use. In the analysis of the cell cycle an effect of sunitinib in case of cell-cycle arrest was shown. However no benefit of adding a histone deacetylase inhibitor was visible. In conclusion, Sunitinib and high osmolarity have an impcat on cells of the clear cell renal cell carcinoma, but there is no additional effect to be seen.

description: Were investigated anisotropic metric of higher dimensional space-time with only cosmological term and scalar field. Showed, that presence of scalar field is equivalent to anisotropic metric in the multy dimensional space-time and proposed idea of dimensions generation by scalar field. Were solved Einstein's equations for higher dimensional space-time of Kazner's type and derived expressions for density of energy for scalar field, which generate additional dimensions, and proposed the procedure of renormalization of the metric.

description: We describe acoustic/prosodic and lexical correlates of social variables annotated on a large corpus of task-oriented spontaneous speech. We employ Amazon Mechanical Turk to label the corpus with a large number of social behaviors, examining results of three of these here. We find significant differences between male and female speakers for perceptions of attempts to be liked, likeability, speech planning, that also differ depending upon the gender of their conversational partners.

description: In conversation, when speech is followed by a backchannel, evidence of continued engagement by one’s dialogue partner, that speech displays a combination of cues that appear to signal to one’s interlocutor that a backchannel is appropriate. We term these cues backchannel- preceding cues (BPC)s, and examine the Columbia Games Corpus for evidence of entrainment on such cues. Entrainment, the phenomenon of dialogue partners becoming more similar to each other, is widely believed to be crucial to conversation quality and success. Our results show that speaking partners entrain on BPCs; that is, they tend to use similar sets of BPCs; this similarity increases over the course of a dialogue; and this similarity is associated with measures of dialogue coordination and task success.
