description: Ziel dieser Arbeit war es die Wirkung des Polyvitamin-B Präparates Polybion N® (Merck, Deutschland) auf die Entwicklung des sekundären Gaumens bei einem hereditär spaltbelasteten Mäusestamm (A/WySn) zu untersuchen. Der A/WySn-Mäusestamm weist eine hohe hereditäre Spaltbildungsrate von 20-44% auf und ist gegenüber teratogenen Einflüssen relativ resistent (Juriloff et al., 1982, Schubert et al., 2002). Die Präparation der Organkulturen erfolgte vor der physiologischen Entwicklung des sekundären Gaumens am 14.8 Tag p.c. und der Entwicklungsstand wurde vor und nach der Inkubation (72 h) bestimmt (Al Obaidi et al., 1995) und statistisch ausgewertet. 89% der Gaumenplattenpaare der A/WySn-Maus wiesen unter Standardbedingungen in der Organkultur nach 72 Stunden kein Wachstum auf. Bei Substitution des Kulturmediums mit Polybion N® konnte jedoch ab einer Medienkonzentration von 0,1% ein signifikantes Wachstum der Gaumenplatten (p0,1%=0,000; p1,0%=0,000) beobachtet werden. Die postive Wirkung der klinischen Prophylaxe mit Poly B-Vitaminen konnte in der Organkultur des sekundären Gaumens der A/WySn-Maus bestätigt werden. Durch die direkte Beeinflussung der Strukturen des sekundären Gaumens kam es zu einer signifikanten Entwicklung dieser Strukturen.
description: This study analyses the direct influence of vitamin B-complex supplements (Polybion®N, Merck Pharma GmbH, Germany) on secondary palate development in palate organ cultures of A/WySnJmice via the supporting media. The inbred strain of A/WySnJ-mice shows a high spontaneous, genetically determined clefting rate of 20-44%. 177 A/WySnJ-fetuses were micro-dissected on the 14.3 GD (gestational day) before palatal fusion takes place. Palatal organ-cultures were prepared and incubated in chemically defined serum-free medium with different concentrations (0.1%, 1.0%) of the vitamin B complex Polybion®N for 72 hours. Palatial development was analysed microscopically according to the six step visual scale of Al-Obaidi (1) that describes the approximation of the palatal shelves during development. At the beginning of the experiment (14.3 GD) the palatal development of all specimens used for the in vitro organ culture showed a clear approach of palatal shelves at stage II. 72 hour after in-vitro cultivation the palatal shelves of the organ-cultures supplemented with vitamin B complex showed a significant growth (p0.1%=0.00017, p1.0%=0.00078) while the untreated control group remained at the initial developmental stage II (p control=0.291). The results of this in vitro study suggest a significant positive influence of vitamin B supplementation on the palatal shelves development in the organ-culture. Further studies will focus on the vitamin B-concentration in the amniotic fluid of mother mice with or without clefts in their offspring.

description: Il presente lavoro propone un’analisi del patto di famiglia visto come fonte di rapporti obbligatori alternativa e concorrente al testamento. Secondo gli autori, in particolare, il patto di famiglia, costituisce una liberalità (art. 809 c.c.) dell'imprenditore  avente ad oggetto il trasferimento dell'azienda o della partecipazione in cui il dovere  degli assegnatari-beneficiari di liquidare le quote di riserva ai legittimari opera come condizione legale risolutiva a tutela dei diritti dei legittimari; secondo gli autori, inoltre, il dovere di liquidazione va inteso  quale adempimento di un'obbligazione indivisibile ex art. 1316 c.c. con interessanti proposte applicative. Funzione tipica del patto di famiglia, in ultima analisi, è coniugare certezza ed efficienza nella gestione del passaggio generazionale dell'impresa  garantendone integrità e continuità, con la giusta protezione delle ragioni individuali del legittimari alla  liquidazione della quota di riserva, cioè con forza ed efficacia pari a quella che sarebbe loro riconosciuta in caso di successione mortis causa.
The novel use of metabolomics as a hypothesis generating technique for analysis of medicinal plants : Ligusticum canbyi Coult. & Rose and Artemisia tridentata Nutt.

description: In response to the environment, plants produce a phytochemical arsenal to communicate and to withstand abiotic and biotic pressures. The average plant tissue contains upwards of 30,000 phytochemicals. The vast majority of approaches used to study plant chemistry are reductionist and only target specific classes of compounds which can be easily isolated or detected. Metabolomics is the qualitative and quantitative analysis of all metabolites present in a biological sample. By providing researchers with a phytochemical snapshot of all existing metabolites present in a sample, metabolomics has allowed researchers to study plant primary and secondary metabolism in ways that were never done before. The first objective of this thesis is to identify candidate species for studying plant neurochemicals. Statistical analysis using residual, bayesian and binomial analysis was applied to the University of Michigan’s Native American Ethnobotany Database and revealed that the genera Artemisa and Ligusticum are used most frequently during ceremony and ritual. Plant melatonin, serotonin, γ-aminobutyric acid, and acetylcholine were quantified in Artemisia tridentata Nutt. and Ligusticum canbyi Coult. & Rose. Significant variability was observed between tissue types, germplasm line and species. Manipulation of cholinergic signalling in A. tridentata led to changes in auxin, melatonin and serotonin levels, and suggests cross-talk between cholinergic and indoleamine pathways could be occurring in plants. The second objective of this thesis is to develop novel statistical and biochemical tools for analyzing metabolomic datasets and hypothesis generation. Datasets were generated using ultra performance reverse phase chromatography with time of flight mass spectrometry detection. Between 16,000 and 40, 000 metabolites were detected in L. canbyi and A. tridentata root and leaf tissues respectively. Principal component analysis, synthetic biotransformation, significant ion generation, putative identification and logical algorithms were applied in order to develop hypotheses and research approaches for pthalide biosynthesis, plant responses to stress, and the biological activity of smoke. Metabolomics, as a field of study, is still in its infancy. Thus approaches to effectively mine datasets are still needed, and provide researchers with new ways to examine the processes which regulate the production of primary and secondary metabolites in vivo.

description: Parity games are a much researched class of games in NP intersect CoNP that are not known to be in P. Consequently, researchers have considered specialised algorithms for the case where certain graph parameters are small. In this paper, we study parity games on graphs with bounded treewidth, and graphs with bounded DAG width. We show that parity games with bounded DAG width can be solved in O(n^(k+3) k^(k + 2) (d + 1)^(3k + 2)) time, where n, k, and d are the size, treewidth, and number of priorities in the parity game. This is an improvement over the previous best algorithm, given by Berwanger et al., which runs in n^O(k^2) time. We also show that, if a tree decomposition is provided, then parity games with bounded treewidth can be solved in O(n k^(k + 5) (d + 1)^(3k + 5)) time. This improves over previous best algorithm, given by Obdrzalek, which runs in O(n d^(2(k+1)^2)) time. Our techniques can also be adapted to show that the problem of solving parity games with bounded treewidth lies in the complexity class NC^2, which is the class of problems that can be efficiently parallelized. This is in stark contrast to the general parity game problem, which is known to be P-hard, and thus unlikely to be contained in NC.

description: In many science and engineering applications, the discretization of linear ill-posed problems gives rise to large ill-conditioned linear systems with right-hand
side degraded by noise. The solution of such linear systems requires the solution of a minimization problem with one quadratic constraint depending on
an estimate of the variance of the noise. This strategy is known as regularization. In this work, we propose to use Lagrangian methods for the solution of the
noise constrained regularization problem. Moreover, we introduce a new method based on Lagrangian methods and the discrepancy principle. We present numerical results on numerous test problems, image restoration and medical imaging
denoising. Our results indicate that the proposed strategies are effective and efficient in computing good regularized solutions of ill-conditioned linear systems
as well as the corresponding regularization parameters. Therefore, the proposed methods are actually a promising approach to deal with ill-posed problems.

description: Gas-giant planets that form via core accretion might have very different characteristics from those that form via disk-instability. Disk-instability objects are typically thought to have higher entropies, larger radii, and (generally) higher effective temperatures than core-accretion objects. We provide a large set of models exploring the observational consequences of high-entropy (hot) and low-entropy (cold) initial conditions, in the hope that this will ultimately help to distinguish between different physical mechanisms of planet formation. However, the exact entropies and radii of newly-formed planets due to these two modes of formation cannot, at present, be precisely predicted. We introduce a broad range of "Warm Start" gas-giant planet models. Between the hottest and the coldest models that we consider, differences in radii, temperatures, luminosities, and spectra persist for only a few million to a few tens of millions of years for planets that are a few times Jupiter's mass or less. For planets that are ~five times Jupiter's mass or more, significant differences between hottest-start and coldest-start models persist for on the order of 100 Myrs. We find that out of the standard infrared bands (J, H, K, L', M, N) the K and H bands are the most diagnostic of the initial conditions. A hottest-start model can be from ~4.5 magnitudes brighter (at Jupiter's mass) to ~9 magnitudes brighter (at ten times Jupiter's mass) than a coldest-start model in the first few million years. In more massive objects, these large differences in luminosity and spectrum persist for much longer than in less massive objects. We consider the influence of atmospheric conditions on spectra, and find that the presence or absence of clouds, and the metallicity of an atmosphere, can affect an object's apparent brightness in different bands by up to several magnitudes.

description: As phraseology moves ever more into the mainstream of corpus linguistics research, it is no longer acceptable to limit the language studied to canonical, dictionary citation forms. But how can others be retrieved, when precise forms they take are not known? This paper sets out some general principles for retrieving non-canonical examples, using collocational frameworks, and expands upon the utility of analysing the innovative alongside the ordinary.

description: Abstract: Far from being linguistic anomalies, multi-word expressions abound in natural language, yet their identification is surprisingly problematic. The same combination of words can occur as a compositional, fully lexical string or as a delexicalised multi-word unit (MWU). How can these different manifestations of a series of words be distinguished one from the other? To exacerbate the problem, the creativity of language users results in the appearance of non-canonical forms of MWUs. How can these innovative uses be retrieved so that they can be incorporated into a comprehensive analysis of the MWU under study? This paper sets forth procedures for retrieving non-canonical variants from large general reference corpora, and addresses the disambiguation of compositional and non-compositional multi-word strings from a collocational standpoint.

description: The use of computer corpora for the analysis of legal language is not common practice; still less the use of parallel corpora for the comparison of legal terminology. The Bononia Legal Corpus project (BoLC) began two years ago, and now as the first stage reaches completion, some important issues must be addressed. This paper will present findings from the first stage of the project, in which European Community directives and judgements have been analysed to identify actual translation equivalents in Italian and English. The main points to be discussed are the clarification of concept boundaries when dealing with terminology in different languages, and the help or hindrance of dictionaries in identifying translation equivalents.

description: For n=1,2,3,... define S(n) as the smallest integer m>1 such that those 2k(k-1) mod m for k=1,...,n are pairwise distinct; we show that S(n) is the least prime greater than 2n-2 and hence the value set of the function S(n) is exactly the set of all prime numbers. For every n=4,5,... we prove that the least prime p>3n with 3|p-1 is just the least positive integer m such that 18k(3k-1) (k=1,...,n) are pairwise distinct modulo m. For d=4,6,12 and n=3,4,...., we prove that the least prime p>2n-2 with p=-1 (mod d) is the smallest integer m such that those (2k-1)^d for k=1,...,n are pairwise distinct modulo m. We also pose several challenging conjectures on primes. For example, we find a surprising recurrence for primes, namely, for every n=10,11,... the (n+1)-th prime p_{n+1} is just the least positive integer m such that 2s_k^2 (k=1,...,n) are pairwise distinct modulo m where s_k = sum_{j=1}^k(-1)^{k-j}p_j. We also conjecture that for any positive integer m there are consecutive primes p_k,...,p_n (k

description: There is a considerable difference between the linguistic content of listening exercises and that of natural, spontaneous speech. The discrepancies that exist stem from the pedagogical practice of 'cleaning up' language for classroom use - i.e. ridding it of distracting noise, repetition, irrelevancies, and so on - and also from an unwillingness to expose learners to unfamiliar lexis and grammatical structures ahead of their treatment within the syllabus. Although such an approach is effective in teaching specific language items, it does not prepare learners for the natural discourse that hey will encounter outside the classroom or self-access centre.
Natural, spontaneous speech is often too difficult for B1 students to understand, not simply because of its speed and lexicogrammatical content, but also, and more importantly, because of the presence of linguistic noise (repetitions and corrections, pauses, unfinished sentences), and implicit knowledge, i.e. that which is not stated rather than that which is. This paper will critique extracts of listening exercises from existing textbooks, demonstrating some of the problems with listening materials in general. This will be followed by a brief exposition of the salient features of natural discourse, as demonstrated through the analysis of spoken corpus data. The author's proposed compromise between the extremes of cleaned-up classroom language and the messiness of natural speech, will be presented in the form of some dialogues created for the ALTAIR project at the University of Bologna.

description: This volume, Exploring Functional Grammar. 2° Edition, the second of the first three e-books of a new series entitled, Functional Grammar Studies for Non-Native Speakers of English, which is contained within the superordinate: Quaderni del Centro di Studi Linguistico-Culturali (CeSLiC), a research center in the Department of Modern Foreign Languages of the University of Bologna. The series proposes a metalinguistic description of English grammar in a functional, socio-semiotic perspective and is proving to be an effective teaching/learning resource for improving English literacy outcomes in the L2 pedagogic setting. The principal ‘consumers’ of the series are the students of the English Language Studies Program (ELSP) in Bologna’s Faculty of Foreign Languages and Literature, for whom it provides the basic course-book in each of their three years of the first-level degree course. The principles and techniques of FG and appraisal theory, introduced in the first year, are further explored in this second volume and applied to short authentic texts, in order to increase the students’ awareness of how meanings are constructed in and by language.

Year: 2012

description: We consider Laplacian eigenfunctions in circular, spherical and elliptical domains in order to discuss three kinds of high-frequency localization: whispering gallery modes, bouncing ball modes, and focusing modes. Although the existence of these modes was known for a class of convex domains, the separation of variables for above domains helps to better understand the "mechanism" of localization, i.e. how an eigenfunction is getting distributed in a small region of the domain, and decays rapidly outside this region. Using the properties of Bessel and Mathieu functions, we derive the inequalities which imply and clearly illustrate localization. Moreover, we provide an example of a non-convex domain (an elliptical annulus) for which the high-frequency localized modes are still present. At the same time, we show that there is no localization in most of rectangle-like domains. This observation leads us to formulating an open problem of localization in polygonal domains and, more generally, in piecewise smooth convex domains.

A 7.7 dB gain was performed at Idss/2 at 18 GHz. However the breakdown voltage has to be improved by lowering the back­ground doping in the Ga1-xAlxAs buffer layer.

description: Aufgrund der Entwicklungen auf dem Sektor der Mobiletelefone ist davon auszugehen, dass die Anzahl kleiner, leichtgewichtiger mobiler Endgeräte, welche als Clients von Datenbanksystemen genutzt werden, weiter ansteigt. Ein wesentliches Problem in diesem Szenario ist die langsame und teure Datenübertragung in Funknetzwerken. Aus Sicht der Nutzer derartiger Technologien ist es somit nicht sinnvoll bzw. wünschenswert, Daten, welche keinen direkten Nutzen für sie bieten, auf das Mobilgerät zu übertragen. Des Weiteren werden einmal empfangene Daten lokal gespeichert und wiederverwendet (Caching). Ändern sich Daten auf dem Server des Informationssystems, müssen die mobilen Clients, welche von einer Änderung betroffen sind, ermittelt und darüber informiert werden. Im Rahmen dieser Dissertation wird gezeigt, dass eine derartige exakte Relevanzprüfung nur mithilfe der Daten in der Datenbank realisiert werden kann. Andere Verfahren, welche das Problem auf semantischer Ebene adressieren, funktionieren nur, wenn die unterstützte Anfragesprache stark eingeschränkt wird und können selbst dann zur falschen Feststellung einer Relevanz führen. Insbesonderen in Informationssystemen mit einer großen Anzahl mobiler Clients kommt es dazu, dass verschiedene Nutzer gleiche oder zumindest ähnliche Anfragen stellen. Diese Eigenschaft wird hier genutzt, um basierend auf einer speziellen Anfragenotation syntaktisch gleiche Teile mehrerer Anfragen gemeinsam auf Relevanz zu testen. Hierzu werden die Anfragen in einem Anfragebaum gespeichert, welcher die IDs der Clients referenziert. Die Relevanzprüfung erfolgt durch Traversieren des Baumes. In der vorliegenden Arbeit werden verschiedene Anfrageindexstrukturen diskutiert und die Menge der notwendigen Relevanztest formal auf der Basis der Relationenmodells hergeleitet. Abschließend werden die theoretisch erarbeiteten Techniken evaluiert und Vorschläge für ihre Optimierung diskutiert.
Cerebral blood flow in man : regulation by arterial blood gases
Creators: name: Willie, Christopher Kenneth
Publisher: name: University of British Columbia
Year: 2014

description: Due to the high metabolic rate of brain tissue and nominal substrate storage, brain perfusion must be precisely regulated to ensure continuous delivery of oxygen and substrates. Cerebral blood flow (CBF) is principally regulated by tissue metabolism, perfusion pressure, autonomic nervous activity, and the partial pressures of arterial oxygen (PaO₂)and carbon dioxide (PaCO₂) – an integrative process thus involving the marked influence of pulmonary gas exchange and cardiovascular function, in addition to intracranial mediators of cerebrovascular resistance. This thesis explicates the roles of PaO₂ and PaCO₂ in human regulation of regional CBF. In study 1, to elucidate their discrete roles, PaO₂ and PaCO₂ were independently manipulated at sea level through the widest range tolerated in humans. Flow reactivity to hypocapnia (low PaCO₂) and hypoxia (low PaO₂) was greater in the vertebral (VA) than internal carotid (ICA) artery, whereas similar reactivity was observed during hypercapnia (high PaCO₂) and hyperoxia (high PaO2₂. Cerebral oxygen delivery was well protected except in cases of extreme hypocapnia. The ventilatory response to hypoxia mitigates falling PaO₂ and reduces PaCO₂, particularly during initial exposure to high altitude. Study 2 assessed regional CBF during ascent to 5050m and every 12 hours during the first 3 days of acclimatization. Although total CBF increased by ~50% and was modestly related to reductions in oxygen saturation of hemoglobin, no regional CBF differences were observed. To extend these findings, Study 3 aimed to determine if cerebrovascular responses to changes in PaO₂ and PaCO₂ differed at 5050m compared to sea level. Despite respiratory alkalosis and partial metabolic compensation at 5050m restoration of PaO₂ to sea level values decreased CBF, and CBF sensitivity to acutely altered PaCO₂ remained similar to sea level. To elucidate the interactive effect on CBF of profound hypoxemia and hypercapnia, study 4 examined the temporal changes in elite breath-hold divers during maximum apneas. Despite 40-50% reductions in arterial oxygen content, CBF elevations were regionally similar (up to +100%) thereby facilitating maintenance of brain oxygen delivery throughout apnea. Although the regulation of CBF is multifaceted, the cerebrovasculature prioritizes oxygen delivery and adjusts to chronic changes in arterial blood gases.

description: A fundamental problem in quantum information is to describe efficiently multipartite quantum states. An efficient representation in terms of graphs exists for several families of quantum states (graph, cluster, stabilizer states), motivating us to extend this construction to other classes. We introduce an axiomatic framework for mapping graphs to quantum states of a suitable physical system. Starting from three general axioms we derived a rich structure which includes and generalizes several classes of multipartite entangled state, like graph/stabilizer states, Gaussian cluster states, quantum random networks and projected entangled pair states (PEPS). Due to its flexibility we can extend the present formalism to include directed and weighted graphs.

description: In this paper a method is proposed for the design of DR-stabilized MESFET oscillators where several diferent design objectives, associated both to stability and output power, can simultaneously be taken into account. First, stability and self-starting capability of an oscillator are related to suitable performance in­dexes which are defined in the paper. Then an efficient procedure aimed at searching for an optimal compromise between opposing design requirements is described. The validity of the whole procedure and the performance in­dexes introduced has been investigated by considering the design of a microstrip parallel-feed back DR oscillator using a medium power GaAs MESFET.

description: Two of the main deficiencies in many of the amplifier synthesis techniques presently in use are that the non-unilateralness of the active devices used is ignored at some stage or other in the design process and that the designer is required to provide initial solutions to the problems he is trying to solve. These problems can be overcome to a large extent by using the concept of the "equivalent passive problem" and by doing intelligent systematic searches. The power of this approach is illustrated with a number of comparative examples.

description: The development of an hybrid dielectric resonator oscillator (DRO) based on a MMIC MESFET is described. Only one circuit was designed to cover the K band frequency range. A common source topology with series feedback was employed. The dielectric resonator is coupled to the gate line of the MESFET. Typical results in the K band frequency range with a 4 V supply voltage are an output power between 11 and 13 dBm and a phase noise better than -80 dBc/Hz at 10 kHz from carrier frequency.

description: We study the relationship between the twisted Orbifold K-theories ${^α}K_{orb}(\textsl{X})$ and ${^{α'}}K_{orb}(\textsl{Y})$ for two different twists $α\in Z^3(G;S^1)$ and $α'\in Z^3(G';S^1)$ of the Orbifolds $\textsl{X}=[*/G]$ and $\textsl{Y}=[*/G']$ respectively, for $G$ and $G'$ finite groups. We prove that under suitable hypothesis over the twisting $α'$ and the group $G'$ we obtain an isomorphism between these twisted K-theories.

description: Die Nah-Infrarot-Spektroskopie (NIRS) ist seit ihrer Aufnahme in die Arzneibücher ein anerkanntes Analyseverfahren in der pharmazeutischen Industrie. Durch den Einsatz von NIRS im Rahmen der Process Analytical Technology (PAT) Initiative der pharmazeutischen Zulassungsbehörden kann das Prozessverständnis verbessert und reproduzierbare Produktqualität sichergestellt werden. In dieser Arbeit wurden at-line NIR-Methoden zur Bestimmung des Wassergehalts und der Partikelgröße von Naproxen-Sodium-Granulaten während des Wirbelschichtprozesses entwickelt. Mithilfe der Wassergehaltsmethode konnte das Prozessdesign der Granulation verbessert werden. Bei einem Wassergehalt größer 21 % im Sprühen wurden ausreichend große Kristallite des Naproxen-Sodium-Anhydrats erhalten, die gegenüber der mechanischen Belastung während der Tablettierung robust waren. So konnten hohe Mengen an amorphen Komponenten, die spontan rekristallisierten, vermieden und die Wirkstofffreisetzung der Tabletten verbessert werden.
description: Near-Infrared Spectroscopy (NIRS) has been an approved analytical process tool in pharmaceutical industry since its inclusion in Pharmacopoeias. With NIRS process design can be adapted to ensure a reproducible product quality as part of the Process Analytical Technology (PAT) initiative of pharmaceutical regulatory authorities. In this thesis at-line NIR methods were developed to determine both water content and particle size during the whole granulation process of Naproxen Sodium. The establishment of a valid method for water content improved the process design of granulation. A water content greater than 21 % during spraying yielded sufficiently large crystallites of anhydrous Naproxen Sodium which were robust against the mechanical stress during compression. The formation of high amounts of amorphous components was thus avoided which spontaneously recrystallize, improving drug release from tablets.

description: This paper tries to give some answers about the analysis and optimization techniques in dealing with microwave GaAs FET oscillators for MMIC applications. The methods treated here are based on multiharmonic formulation in order to take into account the best approach to the real waveform. Some experimental results are presented in order to validate the general approach.
D0 dimuon charge asymmetry from B_s system with Z' couplings and the recent LHCb result

description: The D0 collaboration has announced the observation of the like-sign dimuon charge asymmetry since 2010, which has more than 3σdeviation from the Standard Model prediction. One of the promising explanation is considering the existence of flavor changing Z' couplings to the b and s quarks which can contribute to the off-diagonal decay width in the B_s - \bar{B}_s mixing. Model construction is highly constrained by the recent LHCb data of 1fb^{-1} integrated luminosity . In this paper, we analyze the experimental constraints in constructing new physics models to explain the dimuon charge asymmetry from the CP violation of the B_s system. We present limits on Z' couplings and show that it is impossible to obtain the 1σrange of the dimuon charge asymmetry without the new contribution in the B_d system. Even with arbitrary contribution in the B_d system, the new couplings must be in the fine tuned region.

description: The non-linear behaviour of MOSFETs is historically represented by compact models. Now that MOSFETs are gradually used in high-frequency analogue circuits, techniques originally developed for III-V devices can be applied and adjusted to MOSFETs. We present the development of an accurate table-based MOSFET model and stress the differences with the corresponding HEMT implementation.

description: We find upper and lower bounds of the multiplicities of irreducible admissible representations $π$ of a semisimple Lie group $G$ occurring in the induced representations $Ind_H^Gτ$ from irreducible representations $τ$ of a closed subgroup $H$. As corollaries, we establish geometric criteria for finiteness of the dimension of $Hom_G(π,Ind_H^G τ)$ (induction) and of $Hom_H(π|_H,τ)$ (restriction) by means of the real flag variety $G/P$, and discover that uniform boundedness property of these multiplicities is independent of real forms and characterized by means of the complex flag variety.

COMPARISON OF NARRATIVE STRUCTURE OF J. D. SALINGER’S AND S. ZHADAN’S LITERARY WORKS

description: The narrative structure of the works of the Ukrainian writer Serhiy Zhadan and the American writer Je-rome Seliger are compared. Such works are analyzed: J.D. Salinger's “The Catcher in the Rye”, “Raise High the Roof Beam, Carpenters” and Zhadan’s “Ten Ways to Kill John Lennon”, “Vorochilovgrad”. At the same time the achievements of world narratology are used, namely the theories of Wolf Schmid and Gér-ard Genette. Salinger and Zhadan use narrative strategies to construct works, the core of which is the figure of the nar-rator a young man with a set of certain traits, who undergoes a series of tests of socialization, communicating with different people. Similar motives and a way of their development are allocated. The conclusion is made about the structural similarity of the works and the narrative strategies used, despite the remoteness in time and space. In addition, another pair of works is considered in the center of which is the motive of the narrator's ar-rival to his older brother, who disappeared, and the narrator has to interact with his acquaintances, do his business, that is, involuntarily immerse himself in his brother's life. An analysis of the image of the narrator in selected works, the establishment of key milestones in its development, the search for common features in the works of Ukrainian and American writers are done. In these works, the narrators are at the same time the char-acters of the works, and therefore undergo changes throughout the story. Despite a number of differences, the images of the narrators develop according to one model: from the detached ironic narrators they become in-volved in the story and the narration becomes more frank and sincere.
