Object clitics for subject clitics and DOM phenomena in the Franco-Provençal dialects of Apulia

description: The relation between auxiliaries and argumental properties of the lexical verbs is the question raised by the facts we will investigate. Other issues are posed by the role and the behavior of deictic clitic pronouns in different contexts and in the clitic string. The data examined in this contribution come mainly from the Franco-Provençal dialects spoken in the villages of Celle San Vito and Faeto in North Apulia; these dialects are the heritage linguistic use of ancient minorities dating back to the thirteenth century. We will briefly compare these data with the related data of the Franco-Provençal varieties of West Piedmont. The analysis we propose relies on the idea that auxiliary verbs are not functional elements but preserve their lexical properties, as shown by the identic syntactic behavior of be in its different occurrences. The theoretical frame we follow is the formulation proposed in Chomsky (2020a, b), based on the merge operation and the Labeling Algorithm, leading to a more appropriate treatment of “head movement” and agreeing syntactic structures.

description: Using the charge-conserving Floquet-Green function approach to open quantum systems driven by external time periodic potential, we analyze how spin current pumped (in the absence of any dc bias voltage) by the precessing magnetization of a ferromagnetic (F) layer is injected {\em laterally} into the interface with strong spin-orbit coupling (SOC) and converted into charge current flowing in the same direction. In the case of metallic interface with the Rashba SOC used in experiments [Nature Comm. {\bf 4}, 2944 (2013)], both spin $I^{S_α}$ and charge $I$ current flow within it where $I/I^{S_α} \simeq$ 2--8\% (depending on the precession cone angle), while for F/topological-insulator (F/TI) interface employed in related experiments (arXiv:1312.7091) the conversion efficiency is greatly enhanced $I/I^{S_α} \simeq$ 40--60\% due to perfect spin-momentum locking on the surface of TI. The spin-to-charge conversion occurs also when spin current is pumped {\em vertically} through the F/TI interface with smaller efficiency $I/I^{S_α} \sim 0.001\%$, but with charge current signal being sensitive to whether the Dirac fermions at the interface are massive or massless.

description: Let G a k-step Carnot group. In the 1st part of this talk we are concerned about Integral
Geometry in the setting of Carnot groups. We start by illustrating an interplay between
volume and H-perimeter, using one-dimensional horizontal slicing. This result is a kind
of Fubini Theorem for H-regular hypersurfaces. Some applications are given: slicing of
HBV-functions, integral geometric formulae for volume and H-perimeter and, making use
of a suitable notion of convexity, we state a Cauchy type formula for this class of convex
sets. We then state a sub-Riemannian Santalò formula showing some related applications:
in particular we find two lower bounds for the 1st eigenvalue of the Dirichlet problem for
the Carnot sub-Laplacian  on smooth domains. In the second part we introduce some
differential-geometric tools useful in the study of regular non-characteristic hypersurfaces.
In particular, we state divergence-type theorems and integration by parts formulas with
respect to the intrinsic H-perimeter measure
on hypersurfaces. Finally we shall give a general formula
for the 1st variation of the H-perimeter measure.

Subject clitics in nominal copular sentences: some insight from a North Eastern variety of Italian
Creators: name: Badan, Linda
name: Lorusso, Paolo
Publisher: name: Quaderni di Linguistica e Studi Orientali
Year: 2021

description: In this paper we describe the distribution of subject clitics in nominal copular constructions in the Veneto variety of Este (Padova province). In nominal copular sentences in a pro-drop language like Italian, the copula always agrees with the subject of the small clause both in canonical (preverbal NP subject) and in inverse (postverbal NP subject) structures. Since Veneto varieties are partial pro-drop languages, on the one side, the subject NP always agrees with the copula as in Italian. On the other side, the inflectional paradigm of both verbs and subject clitics interacts with the informational structure of the sentence. Namely, the allowance for subject proclitics and overt postverbal subjects in inverse copular sentences (which is not found in other constructions involving postverbal subjects) allows us to account for the preverbal position of the predicative DP in terms of informational structure: the preverbal predicative DP is a topic intensional element that instantiates the description of the subject of the sentence. The predicative DP, as in Italian, can cliticize onto an invariant pro-predicative clitic: the resulting clustering with the subject clearly confirms the reduced structure involved by copular constructions (as in Moro 1997). The present descriptive considerations allow us to update the analysis of Moro (1997). We characterize inverse copular sentences as involving some restriction on the topic-comment structure, showing a clear morphological counterpart (the inflected subject proclitics) in the operation of AGREE in a partial pro-drop language like the variety of Este (Padova province).

description: Consider the image of a 2n-dimensional unit ball by an open symplectic embedding into the standard symplectic vector space of dimension 2n. Its 2k-dimensional shadow is its orthogonal projection into a complex subspace of real dimension 2k. Is it true that the volume of this 2k-dimensional shadow is at least the volume of the unit 2k-dimensional ball? This statement is trivially true when k = n, and when k = 1 it is a reformulation of Gromov's non-squeezing theorem. Therefore, this question can be considered as a middle-dimensional generalization of the non-squeezing theorem. We investigate the validity of this statement in the linear, nonlinear and perturbative setting.

description: A univariate polynomial f over a field is decomposable if f = g o h = g(h) for nonlinear polynomials g and h. In order to count the decomposables, one wants to know, under a suitable normalization, the number of equal-degree collisions of the form f = g o h = g^* o h^* with (g, h) = (g^*, h^*) and deg g = deg g^*. Such collisions only occur in the wild case, where the field characteristic p divides deg f. Reasonable bounds on the number of decomposables over a finite field are known, but they are less sharp in the wild case, in particular for degree p^2. We provide a classification of all polynomials of degree p^2 with a collision. It yields the exact number of decomposable polynomials of degree p^2 over a finite field of characteristic p. We also present an efficient algorithm that determines whether a given polynomial of degree p^2 has a collision or not.
On improving wind-turbine hub-height wind-speed forecasts
Creators: name: Mason, Jesse Cheyenne
Publisher: name: University of British Columbia
Year: 2014

description: To improve the forecasts of wind speed at the height of wind turbines, I used numerical weather prediction (NWP) models for two types of experiments. One experiment tested the value of better horizontal and vertical resolution in the model, so as to directly forecast the winds at grid points within the height range swept out by the turbine blades instead of interpolating from coarser grid points. The other experiment tested whether forecasts for a cluster of horizontal locations near the wind turbine could yield a better cluster-ensemble average wind forecast than using winds from the one grid point closest to the wind turbine. Three case-study days of poorly forecast fast winds at the Dokie wind farm in northeastern British Columbia were chosen for this study. Dokie is located in the eastern foothills of the Rocky Mountains, where the prevailing westerly winds cause strong mountain waves and downslope windstorms at the wind farm. It was found that better wind speed forecasts are possible for some of the cases when both better vertical and horizontal NWP grid resolutions are used, because these resolutions better capture the dynamics of the mountain weather. It was also found that the cluster-ensemble average wind speeds improve accuracy by compensating for overly-smoothed terrain that NWP models use to maintain numerical stability.

description: We extend the usual chiral perturbation theory framework ($χ$PT) to allow the inclusion of a light dynamical isosinglet scalar. Using lattice QCD results, and a few phenomenological inputs, we explore the parameter space of the effective theory. We discuss the S-wave pion-pion scattering lengths, extract the average value of the two light quark masses and evaluate the impact of the dynamical singlet field in the low--energy constants $\bar{l}_1$, $\bar{l}_3$ and $\bar{l}_4$ of $χ$PT. We also show how to extract the mass and width of the sigma resonance from chiral extrapolations of lattice QCD data.
description: Journal version. Added the study of the scalar two-point function and a discussion of the analytical properties of the sigma pole and its dependence on the quark masses. We clarified the relation of $chi$PT$_S$ with unitarized $chi$PT. Figures 6 and 8 have been improved. 28 pages, 2 tables, 8 figures

Guardianship law : doctrine, theory, objective
Creators: name: Johnson, Michael Leonard
Publisher: name: University of British Columbia
Year: 2014

description: Guardianship is a vital legal process designed to recognize and protect personal and property interests. The societal need for guardianship is growing, yet guardianship law is obscure and its theoretical foundation is uncertain. The first part of this thesis examines the historical foundation and doctrine of English law concerning persons with profound intellectual disabilities – then called “idiots.” Surprisingly, the theory or doctrine of parens patriae played only a limited role. After an examination of the royal prerogatives of the monarch, I conclude guardianship was an “active use” that survived the Statute of Uses. A use is a form of trust, but the phrase “theory of use” is utilized to reflect its unique form, distinguishing it from other kinds of trusts. The second part of this thesis constructs a theoretical framework for guardianship law today. A theory of use recognizes that after the migration of English law to the United States, such a theory must be compatible with state constitutions and must be modified to take into account that change in the form of government. There are two central features of a use, separation of title and protection in a court of equity. Title is separated into a ward’s equitable right and a guardian’s legal title. The guardian is assigned a positive role as legal title holder, especially in relation to other interest holders. Utilizing legal title includes processes of assuming title, protecting the ward’s rights and interests, and acting in the ward’s best interests. A guardian’s wide discretion in a highly individualized context is subject to legal, financial and practical limits. The features of equity are well-suited to protect the ward’s equitable right.
A ghost algebra of the double Burnside algebra in characteristic zero

description: For a finite group $G$, we introduce a multiplication on the $\QQ$-vector space with basis $\scrS_{G\times G}$, the set of subgroups of $G\times G$. The resulting $\QQ$-algebra $\Atilde$ can be considered as a ghost algebra for the double Burnside ring $B(G,G)$ in the sense that the mark homomorphism from $B(G,G)$ to $\Atilde$ is a ring homomorphism. Our approach interprets $\QQ B(G,G)$ as an algebra $eAe$, where $A$ is a twisted monoid algebra and $e$ is an idempotent in $A$. The monoid underlying the algebra $A$ is again equal to $\scrS_{G\times G}$ with multiplication given by composition of relations (when a subgroup of $G\times G$ is interpreted as a relation between $G$ and $G$). The algebras $A$ and $\Atilde$ are isomorphic via Möbius inversion in the poset $\scrS_{G\times G}$. As an application we improve results by Bouc on the parametrization of simple modules of $\QQ B(G,G)$ and also of simple biset functors, by using results by Linckelmann and Stolorz on the parametrization of simple modules of finite category algebras. Finally, in the case where $G$ is a cyclic group of order $n$, we give an explicit isomorphism between $\QQ B(G,G)$ and a direct product of matrix rings over group algebras of the automorphism groups of cyclic groups of order $k$, where $k$ divides $n$.

description: We give a complete characterization of the locally compact groups that are non-elementary Gromov-hyperbolic and amenable. They coincide with the class of mapping tori of discrete or continuous one-parameter groups of compacting automorphisms. We moreover give a description of all Gromov-hyperbolic locally compact groups with a cocompact amenable subgroup: modulo a compact normal subgroup, these turn out to be either rank one simple Lie groups, or automorphism groups of semi-regular trees acting doubly transitively on the set of ends. As an application, we show that the class of hyperbolic locally compact groups with a cusp-uniform non-uniform lattice, is very restricted.

description: A new framework for noncommutative complex geometry on quantum homogeneous spaces is introduced. The main ingredients used are covariant differential calculi and Takeuchi's categorical equivalence for faithfully flat quantum homogeneous spaces. A number of basic results are established, producing a simple set of necessary and sufficient conditions for noncommutative complex structures to exist. Throughout, the family of quantum projective spaces, endowed with the Heckenberger--Kolb calculus, is taken as the motivating set of examples.

description: The concept of dominant interaction hamiltonians is introduced and applied to classical planar electron-atom scattering. Each trajectory is governed in different time intervals by two variants of a separable approximate hamiltonian. Switching between them results in exchange of energy between the two electrons. A second mechanism condenses the electron-electron interaction to instants in time and leads to an exchange of energy and angular momentum among the two electrons in form of kicks. We calculate the approximate and full classical deflection functions and show that the latter can be interpreted in terms of the switching sequences of the approximate one. Finally, we demonstrate that the quantum results agree better with the approximate classical dynamical results than with the full ones.

description: Die akute interstitielle Nephritis (AIN) ist eine Nierenschädigung, die zur Dialyse führen kann. Die Therapie besteht aus dem Absetzen der vermutlich auslösenden Noxe bzw. Behandlung der zugrundeliegenden Erkrankung und/oder einer Steroidtherapie, obwohl ein therapeutischer Nutzen bisher in Studien nicht durchgängig belegt werden konnte. Wir untersuchten 1126 Nierenbiopsien über den Zeitraum von 20 Jahren. 49 (4,4 %) hiervon hatten die Diagnose primäre AIN; 17 von 49 Patienten mit biopsie-gesicherter AIN benötigten eine kurz- oder langfristige (n = 5) Dialyse. 19 Patienten erreichten Remission, während 20 keine Remission erreichten. Bei 39 Patienten lag ein kompletter Datensatz vor. Hier waren die histologische Aktivität (akute Leukozyteninfiltrate), Vernarbungen der Nierenrinde und Proteinurie Parameter, die signifikant mit der Remission korrelierten. Eine Therapie mit Steroiden war mit einer geringeren Wahrscheinlichkeit verbunden, eine Remission zu erreichen (p = 0,008).
description: Acute interstitial nephritis (AIN) is a renal injury causing renal function deterioration and requiring renal replacement therapy (RRT) in a substantial number of cases. Therapy is based on withdrawal of suspicious causative drugs or the underlying diseases and/or steroid application although hard clinical evidence for augmenting steroid therapy is not available. We reviewed the course for 20 years among 1126 biopsied samples. 49 (4.4%) were diagnosed with primary AIN; 17 out of 49 biopsy-proven AIN patients required short-term or long-term (n = 5) RRT. 19 patients reached recovery whereas 20 did not. Among 39 patients with a comprehensive clinical and histopathological data set, presence of cortical scars, AIN histological activity (acute leucocyte infiltrates) and proteinuria were baseline parameters discriminating significantly between groups with or without recovery. Therapeutic use of steroids was associated with a lower probability of recovery (p = 0.008).

description: Die Kettenarchitektur von polymeren Materialien, bestimmt durch Verzweigungen und Defekte, spielt in Bezug auf deren Eigenschaften eine wichtige Rolle. Sie beeinflusst die Kristallisation, welche eine charakteristische Eigenschaft vieler Polymere ist. Der zentrale Punkt dieser Arbeit ist die Untersuchung von Polyethylenglykol-Elastomeren hinsichtlich ihrer Topologie und ihres Kristallisationsverhaltens. Die Synthese von Elastomeren erfolgte von Kooperationspartnern mittels „Click“-Chemie, wodurch chemische Defekte in die Kette eingeführt werden. Im Mittelpunkt der Untersuchungen stand der Einfluss der punktförmigen Defekte und der Kettenvernetzung auf die Ausbildung der kristallinen Phase, die Anordnung von Ketten in den Lamellen sowie auf die intrakristalline Kettendynamik und den Schmelzprozess. Die Untersuchungen wurden mittels NMR sowie komplementären Methoden aus dem Bereich Röntgenstreuung und DSC durchgeführt.
description: The chain architecture of polymeric materials, determined by branching and defects, plays an important role regarding their properties. It influences crystallization, which is a characteristic property of many polymers. The main issue of this thesis is the study of polyethylene glycol elastomers in terms of their topology and crystallization behavior. Elastomers were synthesized in the department of chemistry using click reaction, which introduces chemical defects into the polymer chain. The central issues were the influence of the point defects and chain crosslinking on the formation of the crystalline phase, the arrangement of chains in the lamellae, and on the intracrystalline chain dynamics and melting. The investigations were performed by NMR as well as complementary methods from the field of X-ray scattering and DSC.

description: This paper investigates the benefits of cooperation and proposes a relay activation strategy for a large wireless network with multiple transmitters. In this framework, some nodes cooperate with a nearby node that acts as a relay, using the decode-and-forward protocol, and others use direct transmission. The network is modeled as an independently marked Poisson point process and the source nodes may choose their relays from the set of inactive nodes. Although cooperation can potentially lead to significant improvements in the performance of a communication pair, relaying causes additional interference in the network, increasing the average noise that other nodes see. We investigate how source nodes should balance cooperation vs. interference to obtain reliable transmissions, and for this purpose we study and optimize a relay activation strategy with respect to the outage probability. Surprisingly, in the high reliability regime, the optimized strategy consists on the activation of all the relays or none at all, depending on network parameters. We provide a simple closed-form expression that indicates when the relays should be active, and we introduce closed form expressions that quantify the performance gains of this scheme with respect to a network that only uses direct transmission.

description: We study a special case of Willems's two-user multi-access channel with partially cooperating encoders from a security perspective. This model differs from Willems's setup in that only one encoder, Encoder 1, is allowed to conference; Encoder 2 does not transmit any message, and there is an additional passive eavesdropper from whom the communication should be kept secret. For the discrete memoryless (DM) case, we establish inner and outer bounds on the capacity-equivocation region. The inner bound is based on a combination of Willems's coding scheme, noise injection and additional binning that provides randomization for security. For the memoryless Gaussian model, we establish lower and upper bounds on the secrecy capacity. We also show that, under certain conditions, these bounds agree in some extreme cases of cooperation between the encoders. We illustrate our results through some numerical examples.

description: Poly(esterimide) werden zur Imprägnierung auf Kupferspulen in Elektromotoren verwendet. Während des Betriebes führt ein thermischer Abbau zu einer Einschränkung ihrer Verwendbarkeit. Ziel dieser Arbeit war die Entwicklung eines Sensorsystems zur Überprüfung des Alterungszustandes von Poly(esterimiden). Dafür wurde deren thermischer Abbau hinsichtlich freiwerdender Abbauprodukte untersucht. Es wurden vorwiegend alkoholische Abbauprodukte identifiziert. Folglich wurden alkoholsensitive trifluoroacetyl-funktionalisierte Stilbene synthetisiert und deren Aktivierungskinetik gegenüber verschiedenen nukleophilen Analyten in Lösungsmittelexperimenten untersucht. Die Detektion der Sensoraktivierung erfolgte mittels Fluoreszenzspektroskopie, da sich das Sensor-Emissionsmaximum während der Aktivierung zu niedrigeren Wellenlänge verschob. Schließlich wurden die Sensormoleküle in die Poly(esterimide) eingebracht und deren Funktionalität unter verschiedenen Aktivierungsbedingungen demonstriert.
description: Poly(ester imides) are used as coating material on copper windings in electric motors. In operation, thermal stress leads to their thermal degradation and restricts their usability. Aim of this thesis was the development of a sensor system to detect the aging condition of poly(ester imides). Therefore, their thermal degradation was investigated to identify released degradation products. Alcohols were found to be the main degradation products. Thus, alcohol sensitive, trifluoroacetyl functionalized stilbenes were synthesized and their activation kinetics towards different nucleophilic analytes were tested in solution experiments. The detection of sensor activation was done by fluorescence spectroscopy, as the sensor emission maximum was shifted to shorter wavelengths during activation. Finally, the sensor molecules were embedded within the poly(ester imides) and their suitability was demonstrated using different activation conditions.

description: We demonstrate that the Wigner function of a pure quantum state is a wave function in a specially tuned Dirac bra-ket formalism and argue that the Wigner function is in fact a probability amplitude for the quantum particle to be at a certain point of the classical phase space. Additionally, we establish that in the classical limit, the Wigner function transforms into a classical Koopman-von Neumann wave function rather than into a classical probability distribution. Since probability amplitude need not be positive, our findings provide an alternative outlook on the Wigner function's negativity.

description: We study a property of cycle spaces in connection with degenerating Hodge structures of odd-weight, and construct maps from some partial compactifications of period domains to the Satake compatifications of Siegel spaces. These maps are a generalization of the maps from the toroidal compactifications of Siegel spaces to the Satake compactifications. We also show the continuity of these maps for the case of Calabi-Yau threefolds with h^{2,1}=1.

description: Ziel dieser deskriptiven Studie war die Myalgie-Charakterisierung bei Patienten mit Muskelerkrankungen. Die Druckschmerzerschwelle (PPDT) wurde durch Algesiemetrie bestimmt. Es wurden demografische Informationen, Vordiagnosen, die Myalgielokalisation und der Schmerzcharakter erfragt. Die Hospital Anxiety Depression Scale wurde verwendet, um Depressions- und Angstsymptome zu beurteilen. Die Schmerzempfindung wurde nach der visuellen Analogskala eingestuft. Die Mehrheit der Patienten beschrieb Myalgien in zwei Lokalisationen. Alle Patienten gaben Myalgien in den unteren Extremitäten an. Die Messung der PPDT zeigte einen signifikanten Unterschied zwischen Patienten und Kontrollen. Die Mehrheit der Patienten zeigte normale Ergebnisse bei der HADS-Bewertung. Die PPDT nimmt sowohl bei Patienten als auch bei Kontrollen mit zunehmendem Alter ab. Bei 1/3 der in diese Studie eingeschlossenen Patienten wurde entsprechend ihrer Symptomatik ein Mylagie-Faszikulations-Crampus-Syndrom diagnostiziert.
description: Aim of this descriptive study was the characterization of myalgia in patients with well-defined muscle disease. The pressure pain detection threshold (PPDT) was determined by algesiemetry in patients and controls. In addition to demographic information, known prediagnosis were collected, so as information on myalgia localization ans pain character. Hospital Anxiety Depression scale (HADS) was used to assess for depression and anxiety symptoms. Pain sensation was ranked according to the visual analogue scale. The majority of patients described myalgia in two localizations. Interestingly, all patients named to have myalgia in the lower extremities. The measurement of PPDT showed a significant difference between patients and controls. The majority of patients showed normal results in HADS evaluation. The PPDT decreases in both, patients and controls with age. 1/3 of the patients included into this study were diagnosed according to their symptoms with muscular pain-fasciculation syndrome.

description: Darmkrebs ist einer der führenden Krebserkrankungen weltweit und betrifft in Deutschland jede 8. Krebserkrankung. Die Herunterregulierung der HLA-Klasse-I-Expression kann zu einer schlechten Prognose bei Krebspatienten beitragen. Es gibt nur begrenzte Informationen über die epigenetische und onkogenetische Regulation der HLA-Klasse-I-Molekülen, wobei mehrere Mechanismen beteiligt sein können. In der aktuellen Studie untersuchten wir die Korrelation zwischen dem MAPK-Signalweg und der HLA-Klasse-I-Expression. Resezierte kolorektale Tumorgewebe (n=54) wurden auf p-Erk- und HLA-Klasse-I-Expression mittels Immunhistochemie analysiert und bewertet. In dieser Arbeit konnte eine inverse Korrelation zwischen dem MAPK-Signalweg und der MHC-Molekül-Exprimierung im Kolorektalen Karzinom nachgewiesen werden. Der MAPK-Signalweg bietet eventuelle Angriffspunkte für zukünftige Therapien.
description: Colon cancer is one of the leading tumours in the world and it is considered among the big killers. Downregulation of HLA class I expression may contribute to a poor prognosis in cancer patients. There is limited information about epigenetic and oncogenic regulation of HLA class I, and multiple mechanisms may be involved. In the current study, we examined the relationship between the MAPK-signaling pathway and the expression of HLA class Resected colorectal tumor tissues (n = 54) were analyzed for p-Erk and HLA class I expression by immunohistochemistry. As a result there was a strong inverse correlation between p-Erk expression and HLA class I expression in clinical tumor samples. In conclusion, HLA-A expression is predominantly regulated by the MAPK pathway in colorectal cancer.

description: Fixed Phrases are less fixed than language users believe. But what kind of variation do canonical forms undergo? And how can these variations be retrieved from a corpus?
This paper examines the idiom LIKE A RED RAG TO A BULL in the Bank of English. The attested variants are compared to the twin canonical forms (British and American), and considerations are made regarding the grammatical and semantic consequences of variation.

description: Die post-transkriptionelle Regulation maternaler mRNAs ist essenziell für die frühe Embryonalentwicklung. So ist die Translationsrepression der nanos-mRNA ent-scheidend für die Ausbildung der anterior-posterior-Achse der Drosophila-Embryonen. Die Repression wird durch Bindung vom Protein Smaug an smaug recognition elements (SREs) in der 3‘-UTR der nanos-mRNA vermittelt, worüber wei-tere Proteine, u.a. der Deadenylasekomplex CCR4-NOT, rekrutiert werden. In dieser Arbeit wurde erstmalig der Drosophila-CCR4-NOT-Komplex und die Smaug-abhängige Deadenylierung in vitro rekonstituiert. Smaug allein ist dabei ausrei-chend, um den CCR4-NOT-Komplex zu rekrutieren und führt dadurch zur Deadeny-lierung von SRE-haltigen RNAs. CCR4-NOT allein verhält sich distributiv, wohin-gegen durch Smaug prozessives Verhalten induziert wird. Außerdem wurde mit zell-freien Translationssystem beobachtet, dass Smaug und Cup für die zeitabhängige und stabile Ausbildung des Translationsrepressorkomplexes notwendig sind.
description: Posttranscriptional regulation of maternal mRNAs is essential for early embryonic development. For instance, translational repression of nanos mRNA is critical for the formation of the anterior-posterior axis of the Drosophila embryo. Repression is me-diated through binding of the protein Smaug to smaug recognition elements (SREs) in the 3’ UTR of nanos mRNA. Thereby, additional proteins like the CCR4-NOT deadenylase complex are recruited to the mRNA. Here I report first-time in vitro re-constitution of the Drosophila CCR4-NOT complex and Smaug-dependent dead-enylation. Smaug by itself suffices to cause SRE-specific deadenylation by recruit-ing the CCR4-NOT complex. The CCR4-NOT complex on its own is distributive, whereas in association with Smaug the complex exhibits processive behaviour. Fur-thermore, a cell-free translation system enabled the observation that Smaug and Cup are necessary for the time-dependent and stable formation of the translation repression complex.

description: We discuss the spatiotemporal behavior of local density and its relation to dynamical heterogeneity in a highly supercooled liquid by using molecular dynamics simulations of a binary mixture with different particle sizes in two dimensions. To trace voids heterogeneously existing with lower local densities, which move along with the structural relaxation, we employ the minimum local density for each particle in a time window whose width is set along with the structural relaxation time. Particles subject to free volumes correspond well to the configuration rearranging region of dynamical heterogeneity. While the correlation length for dynamical heterogeneity grows with temperature decrease, no growth in the correlation length of heterogeneity in the minimum local density distribution takes place. A comparison of these results with those of normal mode analysis reveals that superpositions of lower-frequency soft modes extending over the free volumes exhibit spatial correlation with the broken bonds. This observation suggests a possibility that long-ranged vibration modes facilitate the interactions between fragile regions represented by free volumes, to induce dynamical correlations at a large scale.

description: Seit der Antike werden Naturstoffe in großem Umfang zur Behandlung von Krankheiten eingesetzt und sie spielen nach wie vor eine wichtige Rolle in der Arzneimittelforschung. Ziel dieser Arbeit war daher die Identifizierung und Charakterisierung neuer Naturstoffe aus Cyan obakterien für die Arzneimittelentwicklung. Um dieses Ziel zu erreichen, wurden drei verschiedene Ansätze verfolgt. Ein strukturgeleitetes Screening wurde mit HaloSeeker vorgenommen, um neue halogenierte Naturstoffe zu identifizieren. Darüber hinaus wurden zwei verschiedene Bioassay basierte Screening Kampagnen durchgeführt, um Immunmodulatoren und Quorum Sensing Inhibitoren zu identifizieren. Alle drei Screening Ansätze waren erfolgreich bei der Identifizierung neuer bioaktiver Verbindungen aus Cyanobakter ien und verdeutlichen, dass Cyanobakterien eine ergiebige Quelle für bioaktive Naturstoffe sind.

A chemistry guided screening was performed with HaloSeeker in an effort to identify novel halogenated natural products. In addition, two distin ct bioassay based screening campaigns were conducted to identify immunomodulators as well as quorum sensing inhibitors. All three screening approaches were successful in identifying new bioactive compounds from cyanobacteria and illustrate that cyanobacter ia are a prolific source for bioactive natural products.
