description: We have studied how the energy spectrum of muons at production affects some of the most common measurements related to muons in extensive air shower studies, namely, the number of muons at the ground, the slope of the lateral distribution of muons, the apparent muon production depth, and the arrival time delay of muons at ground. We found that by changing the energy spectrum by an amount consistent with the difference between current models (namely EPOS-LHC and QGSjet-II.04), the muon surface density at ground increases $5\%$ at $20^\circ$ zenith angle and $17\%$ at $60^\circ$ zenith angle. This effect introduces a zenith angle dependence on the reconstructed number of muons which might be experimentally observed. The maximum of the muon production depth distribution at $40^\circ$ increases $\sim10\text{ g/cm}^2$ and $\sim0\text{ g/cm}^2$ at $60^\circ$, which, from pure geometrical considerations, increases the arrival time delay of muons. There is an extra contribution to the delay due to the subluminal velocities of muons of the order of $\sim3$ ns at all zenith angles. Finally, changes introduced in the logarithmic slope of the lateral density function are less than 2%.

description: A submodule of a $\mathbb{Z}$-module determines a coloring of the module where each coset of the submodule is associated to a unique color. Given a submodule coloring of a $\mathbb{Z}$-module, the group formed by the symmetries of the module that induces a permutation of colors is referred to as the color group of the coloring. In this contribution, a method to solve for the color groups of colorings of $N$-planar modules where $N=4$ and $N=6$ are given. Examples of colorings of rectangular lattices and of the vertices of the Ammann-Beenker tiling are given to exhibit how these methods may be extended to the general case.

description: Quantum hypothesis testing (QHT) provides an effective method to discriminate between two quantum states using a two-outcome positive operator-valued measure (POVM). Two types of decision errors in a QHT can occur. In this paper we focus on the asymmetric setting of QHT, where the two types of decision errors are treated unequally, considering the operational limitations arising from the lack of a reference frame for chirality. This reference frame is associated with the group $\bbZ_2$ consisting of the identity transformation and the parity transformation. Thus, we have to discriminate between two qubit states by performing the $\bbZ_2$-invariant POVMs only. We start from the discrimination between two pure states. By solving the specific optimization problem we completely characterize the asymptotic behavior of the minimal probability of type-II error which occurs when the null hypothesis is accepted when it is false. Our results reveal that the minimal probability reduces to zero in a finite number of copies, if the $\bbZ_2$-twirlings of such two pure states are different. We further derive the critical number of copies such that the minimal probability reduces to zero. Finally, we replace one of the two pure states with a maximally mixed state, and similarly characterize the asymptotic behavior of the minimal probability of type-II error.

Year: 1995

description: A hospital based cross sectional study was carried out in order to describe the magnitude of antituberculosis drug resistance and identify the risk factors associated with it. The study was carried out in Harar tuberculosis centre which is the major tuberculosis treatment centre in eastern Ethiopia. A total of 338 smear/culture positive patients were enrolled in the study between October 10, 1994 and January 20, 1995. Exposure status was determined through interview; drug resistance and HIV status were determined through laboratory investigation. The overall prevalence of resistance to one or more anti-tuberculosis drugs was 126/338 (37.3%). Initial resistance was 82/252 (32.5%) while that of acquired was 44/86 (51 . 2%). History of previous treatment was the strongest predictor of anti-tuberculosis drug resistance (p <0 . 005). HIV infection was found to be an important predisposing factor in those who had history of previous treatment (p< 0.05). The prevalence of drug resistance is high in Harar. There is a need for periodic national drug resistance survey. Implementation of the WHO recommended supervised treatment with multi-sectoral approach is suggested

description: Η παρούσα έρευνα σχεδιάστηκε με σκοπό αφενός να γίνει ανίχνευση των κινητικών δυσκολιών και αφετέρου η αξιολόγηση της συμμετοχής σε φυσική δραστηριότητα σε νεαρούς ενήλικες νοσηλευτές/τριες, ηλικιακού εύρους 18-30 ετών και θα αξιολογηθεί η σχέση μεταξύ της εμφάνισης κινητικών δυσκολιών και της συμμετοχής σε φυσική δραστηριότητα. Στην έρευνα συμμετείχαν 30 νοσηλευτές/τριες του Γενικού Νοσοκομείου Σερρών, 3 άνδρες και 27 γυναίκες από 18 έως 29 ετών, υγιείς, χωρίς κάποια διαγνωσμένη διαταραχή είτε νευρολογική, είτε κινητική, είτε νοητική. Ως εργαλεία μέτρησης στην έρευνα χρησιμοποιήθηκαν το ερωτηματολόγιο Adult Developmental Coordination Questionnaire (ADC), το οποίο έχει σχεδιαστεί να ανιχνεύει και να αξιολογεί τις κινητικές δυσκολίες σε νέους και το ερωτηματολόγιο Godin – Leisure Time Physical Activity Questionnaire - για αξιολόγηση της φυσικής δραστηριότητας των συμμετεχόντων. Από τα αποτελέσματα φάνηκε ότι το ποσοστό εμφάνισης κινητικών δυσκολιών στους νεαρούς ενήλικες νοσηλευτές/τριες συμφωνεί με το ποσοστό εμφάνισής τους στο γενικό πληθυσμό των ενηλίκων που αναφέρεται στη διεθνή βιβλιογραφία. Ακόμα, το επίπεδο της εβδομαδιαίας ΦΔ των νεαρών ενήλικων νοσηλευτών συμφωνεί με τις παγκόσμιες συστάσεις για επαρκή επίπεδα ΦΔ. Τέλος, η εμφάνιση κινητικών δυσκολιών κατά την παιδική τους ηλικία φάνηκε να σχετίζεται με μειωμένη εβδομαδιαία συχνότητα συμμετοχής τους σε ΦΔ ως νεαροί ενήλικες
description: The present study was designed with the aim of detecting motor difficulties and, on the other hand, to evaluate the participation in physical activity in young adult nurses (male/female), aged 18-30 years, and the relationship between the occurrence of motor difficulties and participation in physical activity. 30 nurses of the General Hospital at Serres, 3 men and 27 women from 18 to 29 years of age, healthy, without any diagnosed neurological, motor or mental disorder participated in the study. The Adult Developmental Coordination Questionnaire (ADC), which was designed to detect motor difficulties in young people, and the Godin-Leisure Time Physical Activity Questionnaire which assesses physical activity of participants, were used as measurement tools. The results showed that the occurrence of motor difficulties in young adult nurses agrees with the occurrence reported in the international literature. Furthermore, the level of weekly PA of young adult nurses is in line with the global recommendations for adequate levels of PA. Finally, the occurrence of motor difficulties in childhood found to be correlated with reduced weekly participation in physical activity as young adults

description: This thesis presents a methodology for automatically generating online scheduling algorithms for a complex objective defined by a machine provider. Such complex objective functions are required if the providers have several simple objectives. For example, the different relationships to the various users must be incorporated during the development of appropriate scheduling algorithms. Our research is focused on online scheduling with independent parallel jobs, multiple identical machines and a small user community. First, Evolutionary Algorithms are used to exemplarily create a 7-dimensional solution space of feasible schedules of a given workload trace. Within this step no preferences between different basic objectives need to be defined. This solution space enables the resource providers to define a complex evaluation objective based on their specific preferences. Second, optimized scheduling strategies are generated by using two different approaches. On the one hand, an adaptation of a Greedy scheduling algorithm is applied which uses weights to create an order of jobs. These job weights are extracted again from workload traces with the help of Evolutionary Algorithms. On the other hand, a Fuzzy rule based scheduling system will be applied. Here, we classify a scheduling situation which consists of many parameters like the day time, the week day, the waiting queue length etc. Depending on this classification, a Fuzzy rule based system chooses an appropriate sorting criterion for the waiting job queue and a suitable scheduling algorithm. Finally, both approaches, the Greedy scheduling strategy and the Fuzzy rule based scheduling system, are compared by using again workload traces. The achieved results demonstrate the applicability of our approach to generate such multi-objective scheduling strategies.

Ground states of the Triangular Ising model with two-and three-spin interactions
Creators: name: Stolze, Joachim
name: Brandt, Uwe
Publisher: name: Springer-Verlag
Year: 1986
Subjects: subject: 510

description: The possible ground state spin configurations of an Ising model on a plane triangular lattice are investigated. The model incorporates competing interactions between spins at nearest and next-nearest neighbour sites as well as a coupling between three spins at the vertices of a nearest-neighbour triangle, and an external magnetic field. Models of this type are frequently used to describe the structures of adsorbate layers on hexagonal substrates. The analysis is based on linear inequalities involving the magnetization, two- and three-spin correlations, and on simple convexity arguments. Part of the inequalities needed are proved with the aid of a computer. For vanishing three-spin coupling the results of earlier studies are confirmed; in addition, the resulting seven topologically distinct structures are shown to be unique. Two of these structures are energetically degenerate; the degeneracy cannot be lifted by any further two-spin interaction. For nonzero three-spin coupling only an "almost complete" solution is given, involving four additional spin configurations. The "ground state phase diagrams" are discussed.
On Mean Field Theories of Singlet Superconductivity in Extended Hubbard Models
Creators: name: Stolze, Joachim
Publisher: name: Springer-Verlag
Year: 1986
Subjects: subject: 510

description: Hubbard models extended by attractive interactions between nearest neighbours have recently been discussed as models for heavy fermion superconductivity. Here, a comparison is carried through between mean field calculations at finite band width and exact results on ground state properties in the atomic limit (i.e. at zero band width). It turns out that the mean field approximation does not provide an appropriate description of the ground state of the system. This holds true for arbitrary band filling. For half-filled band, an extended mean field approximation is studied, allowing for both antiferromagnetism and (singlet) superconductivity. It is found that these two types of order do not coexist within mean field theory.

description: We calculate the quasiparticle density of states (DoS) inside the vortex core in a granular superconductor, generalizing the classical solution applicable for dirty superconductors. A discrete version of the Usadel equation for a vortex is derived and solved numerically for a broad range of parameters. Electron DoS is found to be gapful when the vortex size $ξ$ becomes comparable to the distance between neighboring grains $l$. Minigap magnitude $E_g$ grows from zero at $ξ\approx 1.4 l$ to third of superconducting gap $Δ_0 $ at $ξ\approx 0.5 l$. The absence of low-energy excitations is the main ingredient needed to understand strong suppression of microwave dissipation recently observed in a mixed state of granular Al.

description: We introduce the Gaussian Mixture full Photometric Red sequence Cluster Characteriser (GMPhoRCC), an algorithm for determining the redshift and richness of a galaxy cluster candidate. By using data from a multi-band sky survey with photometric redshifts, a red sequence colour magnitude relation (CMR) is isolated and modelled and used to characterise the optical properties of the candidate. GMPhoRCC provides significant advantages over existing methods including, treatment of multi-modal distributions, variable width full CMR red sequence, richness extrapolation and quality control in order to algorithmically identify catastrophic failures. We present redshift comparisons for clusters from the GMBCG, NORAS, REFLEX and XCS catalogues, where the GMPhoRCC estimates are in excellent agreement with spectra, showing accurate, unbiased results with low scatter ($σ_{δz / (1+z)} \sim 0.014$). We conclude with the evaluation of GMPhoRCC performance using empirical Sloan Digital Sky Survey (SDSS) like mock galaxy clusters. GMPhoRCC is shown to produce highly pure characterisations with very low probabilities ($<1\%$) of spurious, clean characterisations. In addition GMPhoRCC is shown to demonstrate high rates of completeness with respect to recovering redshift, richness and correctly identifying the BCG.

description: Η παρούσα εργασία αφορά σε μια σειρά μαθημάτων που βασίζονται στο Ανοιχτό Θέατρο και αντλούν από την έννοια της Κριτικής Παιδαγωγικής του Paulo Freire και τις εκπαιδευτικές προοπτικές που έχει το Θέατρο του Καταπιεσμένου του Augusto Boal. Το Ανοιχτό Θέατρο, ως μορφή τέχνης μπορεί να χρησιμοποιηθεί στην εκπαίδευση για να καλλιεργήσει την κοινωνική συνείδηση των μαθητών σε θέματα που σχετίζονται με την καταπίεση και να τους ενθαρρύνει να συντελέσουν στην κοινωνική αλλαγή. Οι παρεμβάσεις του Ανοιχτού Θεάτρου πραγματοποιήθηκαν σε ένα ελληνικό Πειραματικό Δημοτικό Σχολείο στα πλαίσια της διδασκαλίας των Αγγλικών ως δεύτερης ξένης γλώσσας σε μαθητές. Τα μαθήματα πραγματεύονται το ζήτημα του σχολικού εκφοβισμού ως μια μορφή καταπίεσης που οι μαθητές γνωρίζουν. Ο σχεδιασμός των μαθημάτων στοχεύει τόσο στην γλωσσική ανάπτυξη των μαθητών όσο και στην κοινωνική τους ενδυνάμωση. Αναμένεται πως η εφαρμογή των θεατρικών τεχνικών, που είναι εμπνευσμένες από τον Boal, θα βελτιώσει την αλληλεπίδραση των μαθητών στην δεύτερη γλώσσα, θα ενισχύσει την ενσυναίσθηση τους, θα προωθήσει την συνεργασία με τους συμμαθητές τους, και θα συνεισφέρει στην ικανότητα τους να επιλύουν προβλήματα
description: Starting from Paulo Freire’s concept of Critical Pedagogy and combining it with Augusto Boal’s drama education in the Theatre of the Oppressed (TO), a series of Forum Theatre sessions were designed for the current project. Forum Theatre, as an art form, can be used in the educational context to cultivate students’ consciousness on social issues involving oppression and encourage them to induce social change. The Forum Theatre interventions were implemented with students at a Greek Experimental Primary School during their English as a Second Language (ESL) classes. The lessons addressed the issue of school bullying which is a form of oppression that young learners are familiarised with. The conceptualization of the lessons has both linguistic and social empowerment objectives. It is expected that the application of Boal’s dramatic techniques will improve students’ interaction in the second language (L2), cultivate their empathy, promote effective collaboration with their peers, and contribute to their problem-solving skills

description: Background: Globally an estimated number of 20 million cases and 164,000 deaths occur from measles each year. Airborne transmission of measles virus has been documented with reproduction ratio (RR) of 12-18. Measles is still a public health problem in many developing countries, particularly in parts of Africa and Asia. The aim of investigation was to identify etiologic agent, risk factors and institute doable intervention measures. Methods: A 1:2 unmatched case-control study was applied from December 20-30/2014 and data were collected using structured questionnaire. The data were entered in to SPSS version 16, Epiinfo7 and MS-Excel work sheet, Odds Ratio, 95% CI and P-value were constructed to measure the significance of association in bivariate and multivariate analysis. Results: The outbreak stayed for 24 weeks and a total of 404 suspected cases of measles and six cases were died with CFR of 1.5%. The mean age of the cases was 11.9 years with a range of 9 months - 35 years and mean age of controls was 5.5 years with a range of 1-21 years. The overall attack rate (AR) of the case was 163/100,000 populations. Odds of illness among non vaccinated (AOR: 5; 95% CI: 1.5-16.2; P: 0.006) compared to vaccinated, odds of illness among people with contact (AOR: 19.6; 95% CI: 1.3-290; P< 0.029) compared to people without contact with cases, odds of illness among people with travel history (AOR: 14.9; 95% CI: 3.8-58; P< 0.001) compared to without travel history, odds of illness among age group from 5-15 years (AOR: 38.5 ; 95% CI: 3.6-410; p < 0.002) compared to others. These were significant factors in both bivariate and multivariate analysis. Conclusion: Unvaccinated children less than 15 years of age were primarily affected by this outbreak. The case fatality rate was greater than 1%. Delayed case management and late investigation worsened the situation of an outbreak in the affected locality. Absence of vaccination, contact with the suspected individuals and travel history to affected areas were found to be risk factors. Mass vaccination and active case management to contain the epidemics is strongly recommended. Key words: Measles, Outbreak, Fogera, Ethiopia

description: Ages are key to truly understand a large plethora of astrophysical phenomena. On the other hand, stellar clusters are open windows to understand stellar evolution, specifically, the change with time and mass of different stellar properties. As such, they are our laboratories where different theories can be tested, but without accurate ages, our knowledge would impaired. We revisit here a large number of age-dating techniques and discuss their advantages and draw-backs. In addition, a step-by step process is suggested in order to built a coherent age scale ladder, minimizing the error budget and the sources of uncertainty.

description: This portfolio highlights the benefits of integrating digital media into the EFL classroom but it also investigates the role as well as the advantages of incorporating literature. It proposes the development of an ELT coursebook which embodies the use of both technology and literature within the communicative and learner-centered frameworks of TBLT and CLIL, while catering for the promotion of 21st Century Skills. The coursebook is composed of two units and an additional literature section. The purpose of this coursebook is to propose an alternative to the current material designing practices by adopting a holistic approach as regards the English language teaching practice. The paper starts by demonstrating the underlying philosophy of teaching behind the choices being made for the implementation of this coursebook. It, then, moves on to elucidate and justify the incorporation of digital media in conjunction with the use of literature within the TBLT and CLIL framework. After that, it demonstrates the overall course syllabi, and delineates the particular learning objectives and outcomes of each lesson included in the coursebook. Finally, the thesis ends by touching upon some limitations of this proposal, and generally reflecting on the paper
Effect of Topical Application of Human Breast Milk, Chlorhexidine and Dry Cord Care on Neonatal Umbilical Cord Separation Time and Rate of Cord Infection in Butajira, Ethiopia 2017/2018: Cluster Randomized Trial

description: Background- Annually 1 million newborns worldwide die of infection caused by bacteria that enter the body via the umbilical cord. Regarding this the Ethiopia national strategy of new born and child survival identified chlorhexidine (CHX) as one of the high impact intervention to minimize neonatal mortality. Whereas, studies have shown Human breast milk (HBM) application to the neonatal umbilical cord has a shorter cord separation time and lower rate of infection than CHX or the standard dry cord care (DCC). To the best of the investigators knowledge on to assess cord separation time and rate of cord infection, studies were not conducted comparing the standard DCC with that of CHX or HBM. Objective: - Compare the effect of topical application of HBM, CHX and DCC on neonatal umbilical cord separation time (CST) and assess the rate of cord infection at the Demographic and Health Surveillance Site, Butajira, Ethiopia, 2017/18. Method- From May to November, 2018, a three arm, non- masked, community based, cluster randomized controlled trial was conducted at Butajira Demographic and Health Surveillance site (BDHSS) located in Gurage Zone of the Southern Nations, Nationalities and Peoples´ Region (SNNPR) of Ethiopia. Nine kebeles of the BHDSS were randomized into two intervention groups i.e. HBM and CHX and a control group which is the standard DCC using a lottery method. From a sample size of 337, data were entered and analyzed for 302 term singleton newborns. Baseline characteristics across the groups were compared by ANOVA for continuous variables and Chi square for categorical variables. Mean CST was compared among the groups using one way ANOVA whereas the secondary outcome i.e. rate of omphalities was expressed in terms of frequency and was compared among the groups using Chi square. Level of significance was set at p <0.05 with 95% CI. Result- The mean cord separation time was 5.6 days in HBM group, 5.9days in CHX group, and 5.7days in DCC group but this difference was not statistically significant among the study groups (p value=0.40). The highest signs of cord infection rate were observed in dry care group and this was significant regarding the redness on the base of the cord stump (P<0.001). Conclusion and recommendations- Topical application of HBM is related with shorter cord separation time compared to CHX or DCC. It also has reduced incidence of infection, as much as topical CHX application. Generally the readily available human breast milk should be given further emphasis.

description: Quantum Hamilton-Jacobi quantization scheme uses the singularity structure of the potential of a quantum mechanical system to generate its eigenspectrum and eigenfunctions, and its efficacy has been demonstrated for several well known conventional potentials. Using a recent work in supersymmetric quantum mechanics, we prove that the additive shape invariance of all conventional potentials and unbroken supersymmetry are sufficient conditions for their solvability within the quantum Hamilton-Jacobi formalism.

description: We review the problem of spin decoherence of magnetic atoms deposited on a surface. Recent breakthroughs in scanning tunnelling microscopy (STM) make it possible to probe the spin dynamics of individual atoms, either isolated or integrated in nanoengineered spin structures. Transport pump and probe techniques with spin polarized tips permit measuring the spin relaxation time $T_1$, while novel demonstration of electrically driven STM single spin resonance has provided a direct measurement of the spin decoherence time $T_2$ of an individual magnetic adatom. Here we address the problem of spin decoherence from the theoretical point of view. First we provide a short general overview of decoherence in open quantum systems and we discuss with some detail ambiguities that arise in the case of degenerate spectra, relevant for magnetic atoms. Second, we address the physical mechanisms that allows probing the spin coherence of magnetic atoms on surfaces. Third, we discuss the main spin decoherence mechanisms at work on a surface, most notably, Kondo interaction, but also spin-phonon coupling and dephasing by Johnson noise. Finally, we propose some schemes to engineer spin decoherence.

description: Back ground: Podoconiosis is non-infective, usually crystalline Blockage of the limb lymphatic, almost always affecting the lower limbs. In Ethiopia Podoconiosis is an important public health problem in endemic areas like Wolaita zone. Podoconiosis has a serious social and psychological burden. The importance of assessment of quality of life has gained considerable value in recent years .There are several benefits of measuring QOL. Objectives: The objective of the study was to asses the applicability of DLQI in measuring the quality of life of Podoconiosis patients. Methods: A cross sectional study was conducted in wolaita zone, SNNPR Ethiopia in eight MFTPA`s outreach sites using the translated Amharic version of DLQI. Results: the questioners were administered to 148 Podoconiosis patients, 80 males and 68 females. Patients' ages ranged from 17-78 years (mean 35.95 years, SD 16.112,).fifty percent were new patients and the rest were patients treated for a minimum of three months at MFTPA. Twenty eight (18.9%) of patients were from urban areas and the rest were from rural sites. The Cronbach`s alpha was 0.71 among treated patients and 0.78 among new patients. Item total correlation ranged from 0.39-0.47. The DLQI score for new patients ranged from 4 to 21 (mean 12.76, median 13.00, SD 3.81) and those for treated patients ranged from 1 to 18 (mean 4.08, median 3.00, SD 3.16). The ranked mean difference between the two groups was statistically significant. (Z=-0.9477, p value< 0.000). There was no statistically significant difference between age, sex and outreach sites groups regarding the overall DLQI score. Conclusions: In conclusion it was found that the Amharic version of the DLQI was a valid, reliable and acceptable for measuring the quality of life of Podoconiosis patients in the study settings and a three or more month treatment by MFTPA is associated with improving the quality of life.

description: Το πρόβλημα της Ταυτόχρονης Χαρτογράφησης και Εντοπισμού (SLAM) έχει απασχολήσει ερευνητές για πολλές δεκαετίες. Το πρόβλημα αποτελείται από έναν πράκτορα, ο οποίος κινείται σε ένα περιβάλλον και λαμβάνει πληροφορίες από αυτό (συνήθως οπτικές) για να δημιουργήσει ένα χάρτη στη μνήμη του και να εντοπίζει την τοποθεσία του σε αυτόν το χάρτη ανά πάσα στιγμή. Το ORB-SLAM είναι ένα τελευταίας τεχνολογίας σύστημα SLAM. Βασίζεται στην τεχνική αναπαράστασης εικόνων ORB, η οποία παρέχει έναν τρόπο να περιγραφεί μία εικόνα με συνέπεια και να βρεθούν εύκολα κοινά σημεία μεταξύ δύο διαφορετικών εικόνων. Στην εργασία αυτή, αναλύουμε και βελτιώνουμε το ORB-SLAM3, κυρίως με τη χρήση μίας πιο προηγμένης τεχνικής αναπαράστασης εικόνων, το BAD. Για το σκοπό αυτό, το σύστημα αναδιαρθρώθηκε ώστε να χρησιμοποιεί το BAD σε όλα τα στάδιά του και αξιολογήθηκε σε διάφορες ακολουθίες video 2 διαφορετικών μεγάλων συνόλων δεδομένων SLAM
description: The problem of Simultaneous Localization and Mapping (SLAM) has occupied researchers for the past several decades. The problem consists of an agent moving through an environment and getting information from it (usually visual) to create a map in its memory and detect its location in that map at all times. ORB-SLAM is a state-of-the-art SLAM system. It is based on the ORB image descriptor, a way to describe an image consistently and find common points between 2 different images easily. This thesis analyzes ORB-SLAM3 and improves it, mainly through a more advanced image descriptor, known as BAD. For this purpose, the system is restructured to use BAD in all its stages and evaluated on various video sequences of 2 different large SLAM datasets

description: Organoelementverbindungen mit einer Silicium-Zinn-Bindung wurden erstmals Mitte der dreißiger Jahre dargestellt. Die Betrachtungen zur Synthese, Reaktivität und spektroskopischen Eigenschaften dieser Substanzklasse beschränkten sich jedoch weitestgehend auf einfache Derivate mit einem Zinn- und einem Siliciumatom. Ziel der vorliegenden Arbeit war, die bisher gewonnen Erkenntnisse über Stannyloligosilane auszuweiten und zu ergänzen. Im Rahmen dieser Arbeit gelang die Darstellung und die Charakterisierung neuartiger offenkettiger und cyclischer Stannylsilane. An den offenkettigen Stannylsilanderivaten wurde die Reaktivität gegenüber Pd(PPh3)4, Sauerstoff und Halogenierungsmitteln untersucht. Reaktivitätsuntersuchungen von Hydridostannylsilanen zeigten, daß einfache Stannylsilanvertreter durch die Umsetzung mit LDA lithiierbar sind. Über die in situ dargestellten Lithiostannylsilane sind durch Umsetzung mit Chlorsilanen neuartige Stannylsilanverbindungen zugänglich. Bei Versuchen zur Darstellung von ausschließlich aus Silicium- und Zinnatomen aufgebauten Bicyclo[2.2.2]octanen werden Umlagerungsreaktionen beobachtet. Es kommt zur Bildung von fünf- oder sechsgliedrigen Ringsystemen. Die Ringe haben durch Hydridfunktionen ein interessantes Synthesepotential.

description: The paper gives a historical survey of the causal position space renormalization with a special attention to the role of Raymond Stora in the development of this subject. Renormalization is reduced to subtracting the pole term in analytically regularized primitively divergent Feynman amplitudes. The identification of residues with "quantum periods" and their relation to recent developments in number theory are emphasized. We demonstrate the possibility of integration over internal vertices (that requires control over the infrared behavior) in the case of the massless $φ^4$ theory and display the dilation and the conformal anomaly.

description: Matrix factorization is an important mathematical problem encountered in the context of dictionary learning, recommendation systems and machine learning. We introduce a new `decimation' scheme that maps it to neural network models of associative memory and provide a detailed theoretical analysis of its performance, showing that decimation is able to factorize extensive-rank matrices and to denoise them efficiently. We introduce a decimation algorithm based on ground-state search of the neural network, which shows performances that match the theoretical prediction.

description: Prospektive monozentrische Studie, welche die Mitralklappen-Funktion nach Clipping mit dem breiten MitraClip der vierten Generation mittels Handgriff-Stressechokardiographie evaluiert. Wir konnten einen signifikanten Anstieg des trasmitralen Druckgradient unter dynamischer Handgriff-Stressechokardiographie beobachten. Jedoch wurde eine pathologische Grenze nicht erreicht. Die Mitralklappeninsuffizienz blieb unter Belastung unverändert. Es zeigte sich eine lineare und signifikante Korrelation zwischen der Anzahl der Clips und dem mittleren transmitralen Gradient bei Belastung.

description: We investigate two stochastic models of a growing population subject to selection and mutation. In our models each individual carries a fitness which determines its mean offspring number. Many of these offspring inherit their parent's fitness, but some are mutants and obtain a fitness randomly sampled from a distribution in the domain of attraction of the Fréchet distribution. We give a rigorous proof for the precise rate of superexponential growth of these stochastic processes and support the argument by a heuristic and numerical study of the mechanism underlying this growth.

description: We study a system of microcavity pillars arranged into a kagome lattice. We show that polarization-dependent tunnel coupling of microcavity pillars leads to the emergence of the effective spin-orbit interaction consisting of the Dresselhaus and Rashba terms, similar to the case of polaritonic graphene studied earlier. Appearance of the effective spin-orbit interaction combined with the time-reversal symmetry-breaking resulting from the application of the magnetic field leads to the nontrivial topological properties of the Bloch bundles of polaritonic wavefunction. These are manifested in opening of the gap in the band structure and topological edge states localized on the boundary. Such states are analogs of the edge states arising in topological insulators. Our study of polarization properties of the edge states clearly demonstrate that opening of the gap is associated with the band inversion in the region of the Dirac points of the Brillouin zone where the two bands corresponding to polaritons of opposite polarizations meet. For one particular type of boundary we observe a highly nonlinear energy dispersion of the edge state which makes polaritonic kagome lattice a promising system for observation of edge state solitons.
