Screening for novel modulators of GABAA receptors
Creators: name: Zhang, Ling
Publisher: name: University of British Columbia
Year: 2013

description: GABAA receptors are a family of ligand gated ion channels that play essential roles both in normal brain functions and psychiatric conditions. While the classical GABAA receptor modulators benzodiazepines have been in clinical use for decades and are still among the most widely prescribed drugs for the treatment of certain disorders, their limitations and side effects have been driving the search for alternative solutions. Recent studies from our lab have demonstrated that glutamate can act as positive allosteric modulators of GABAA receptors, and the suggested binding sites are on the interface of alpha and beta subunits. This surprising finding drove us to pursuit two objectives: (1) screen glutamate-like molecules that can compete with glutamate and prevent the potentiation of GABAA receptors, so we can study the intrinsic functions of the modulating effects of glutamate; (2) screen glutamate-like molecules that can mimic glutamate and potentiate GABAA receptors but do not produce any other physiological effects, so we can utilize them as candidates for clinical treatment as alternatives of benzodiazepines. Experiments are performed on hippocampal neuron cultures and HEK 293 cells transfected with GABAA receptor subunits. Virtual screening and electrophysiology recording are employed. For objective (1), we identified 10 compounds that can inhibit glutamate from potentiating GABAA receptor. Unfortunately, none of them can completely block the potentiation. For objective (2), we identified one compound, 2-methyl aspartic acid (2-MAA), as the final candidate for further study. We found that 2-MAA shares the binding sites with glutamate and potentiates GABAA receptors in a dose-dependent manner, while it does not affect normal neuronal activities. In addition, although it shows no significant effect on tonic GABA current amplitude, it does increase the frequency of mini-IPSCs. In the future, for objective (1), it will require screening for additional candidates and/or modification of the 10 compounds. For objective (2), we can continue testing the anti-epilepsy effect of 2-MAA on both in vitro and in vivo models. It will also be applicable to modify the compound or to screen similar compounds so as to get a better candidate with bigger potentiation at a lower concentration.

description: Reduction of False Positive signals (FPR) is a fundamental, yet awkward, step in computer aided mass detection schemes.
This paper describes preliminary results of a filtering approach to FPR based on Support Vector Regression (SVR), a machine
learning algorithm arising from a well-founded theoretical framework, the Statistical Learning Theory, which has recently
proved to be superior to the conventional Neural Network framework for both classification and regression tasks: indeed, the
proposed filtering method belongs to the family of neural filters.
The SVR filter is forced to associate subregions extracted from input images, masses and non-masses, to continuous output
values ranging from 0 to 1 representing a measure of the presence in the subregion of a mass. A weighted sum of outputs over
each image is used to accomplish the FPR task. In the test phase, this approach reached promising results, retaining 87% of
masses while reducing False Positives to 62%.

description: In der vorliegenden Untersuchung wurden die Fernröntgenseitbilder von insgesamt 134 kieferorthopädisch unbehandelten Patienten mit frontal offenem Biss ausgewertet. Die Beurteilung der kephalometrischen Werte erfolgte mit einer modifizierten Bergen-Analyse (HASUND). Die besondere Ausprägung des Gesichtsschädelaufbaus bei Patienten mit frontal offenem Biss zeigte sich im Vergleich der Messwerte mit den Ergebnissen anderer Populationsstudien. Anhand der Neigungsverhältnisse der Kieferbasen wurden vier verschiedene Erscheinungsformen des offenen Bisses klassifiziert. Die Anwendung zusätzlicher Referenzpunkte ermöglichte eine genauere Beschreibung der Schädelbasismorphologie. Mit Hilfe verschiedener statistischer Verfahren konnte ein Zusammenhang zwischen dem Gesichtsschädelaufbau und den schädelbasisbezüglichen Messwerten nachgewiesen werden.
description: In this study 134 cephalograms of orthodontic untreated patients with an anterior open bite were evaluated. To assess the cephalometric measurements a modified Bergen-Analyse (HASUND) were used. In comparsion to other studies of untreated patients the typical craniofacial pattern of patients with an anterior open bite were demonstrated. With help of the inclinations of upper and lower jaws the open bite could be classified in four characteristic groups. The use of additional landmarks gave the possibility for a better describtion of the morphology of cranial base. With help of different statistical analysis a connection between craniofacial pattern and measurements of cranial base could demonstrated.

description: Let $F(X) = \sum_{n \geq 0} (-1)^{\varepsilon_n} X^{-λ_n}$ be a real lacunary formal power series, where $\varepsilon_n = 0, 1$ and $λ_{n+1}/λ_n > 2$. It is known that the denominators $Q_n(X)$ of the convergents of its continued fraction expansion are polynomials with coefficients $0, \pm 1$, and that the number of nonzero terms in $Q_n(X)$ is the $n$th term of the Stern-Brocot sequence. We show that replacing the index $n$ by any 2-adic integer $ω$ makes sense. We prove that $Q_ω(X)$ is a polynomial if and only if $ω\in {\mathbb Z}$. In all the other cases $Q_ω(X)$ is an infinite formal power series, the algebraic properties of which we discuss in the special case $λ_n = 2^{n+1} - 1$.

description: We discuss in detail and from the geometrical point of view the issues of gauge invariance and Lorentz covariance raised by the approach proposed recently by Chen et al. to the proton spin decomposition. We show that the gauge invariance of this approach follows from a mechanism similar to the one used in the famous Stueckelberg trick. Stressing the fact that the Lorentz symmetry does not force the gauge potential to transform as a Lorentz four-vector, we show that the Chen et al. approach is Lorentz covariant provided that one uses the suitable Lorentz transformation law. We also make an attempt to summarize the present situation concerning the proton spin decomposition. We argue that the ongoing debates concern essentially the physical interpretation and are due to the plurality of the adopted pictures. We discuss these different pictures and propose a pragmatic point of view.

description: We propose a form factor approach for the computation of the large distance asymptotic behavior of correlation functions in quantum critical (integrable) models. In the large distance regime we reduce the summation over all excited states to one over the particle/hole excitations lying on the Fermi surface in the thermodynamic limit. We compute these sums, over the so-called critical form factors, exactly. Thus we obtain the leading large distance behavior of each oscillating harmonic of the correlation function asymptotic expansion, including the corresponding amplitudes. Our method is applicable to a wide variety of integrable models and yields precisely the results stemming from the Luttinger liquid approach, the conformal field theory predictions and our previous analysis of the correlation functions from their multiple integral representations. We argue that our scheme applies to a general class of non-integrable quantum critical models as well.

description: Integrated optical and millimetric circuits produced by standard thin film-based technology suffer from manufacturing imperfections resulting in degradation of the absorption/diffraction response. Deposition through rf-bias sputtering is of particular interest in order to design an optical multilayered (Si and SiO2) filter. Geometrical imperfections like roughness at layer boundaries however gradually increase with the number of deposited layers. The low-pass filter specifications present high sensitivity to the errors of the exact values of ideal thickness and of ideal refractive indices. In this contribution, we evaluate the sensitivity of the specifications with respect to deviation from the exact values of refractive indices and thicknesses.

description: We report on some advances made in the problem of singularities in general relativity. First is introduced the singular semi-Riemannian geometry for metrics which can change their signature (in particular be degenerate). The standard operations like covariant contraction, covariant derivative, and constructions like the Riemann curvature are usually prohibited by the fact that the metric is not invertible. The things become even worse at the points where the signature changes. We show that we can still do many of these operations, in a different framework which we propose. This allows the writing of an equivalent form of Einstein's equation, which works for degenerate metric too. Once we make the singularities manageable from mathematical viewpoint, we can extend analytically the black hole solutions and then choose from the maximal extensions globally hyperbolic regions. Then we find space-like foliations for these regions, with the implication that the initial data can be preserved in reasonable situations. We propose qualitative models of non-primordial and/or evaporating black holes. We supplement the material with a brief note reporting on progress made since this talk was given, which shows that we can analytically extend the Schwarzschild and Reissner-Nordstrom metrics at and beyond the singularities, and the singularities can be made degenerate and handled with the mathematical apparatus we developed.

description: Das Museum gehört zu den klassischen bürgerlichen Einrichtungen des 19. Jahrhunderts. Abseits der dominierenden ideengeschichtlichen Erklärungsmodelle bietet die Arbeit einen neuen sozial- und mentalitätsgeschichtlichen Zugang zur Deutung dieses Phänomens. Ausgehend von einem mikrohistorischen Umfeld, der Genese der Osnabrücker Museumslandschaft, werden neue Erkenntnisse über die allgemeine Bürgertums- und Museumsgeschichte des 19. und beginnenden 20. Jahrhunderts gewonnen. Dabei wird unter anderem sichtbar, daß die deutschen Museen in den Zentren mit denjenigen an der Peripherie viel deutlicher in Wechselwirkung zueinander standen bzw. stehen und sich gegenseitig weit stärker beeinflußten, als dies bislang wahrgenommen worden ist. Im Mittelpunkt der Untersuchung steht eine Anthropologie des Sammelns, auf deren Grundlage der Zusammenhang zwischen der Institution Museum und der Ausprägung bürgerlicher Identität veranschaulicht wird. Indem die Musealisierungs- und Professionalisierungphase des untersuchten Zeitraums als Prozeß der Institutionalisierung des Sammelns beschrieben wird, zeigt sich, daß das Museum als Ort musealer Vergesellschaftung fungierte und damit zur Überwindung gesellschaftlicher Binnengrenzen beitrug. Zudem wird deutlich, daß durch die starke individuelle Prägung von Museumssammlungen im Kontext der Verstetigung von Lebensgeschichte(n) Museen stärker als "Museumsindividuen" zu begreifen sind.
description: The museum is one of the classical 19th century bourgeois institutions. This study offers an explanation of the phenomenon in terms of historical changes in society as well as in mentality, aside from interpretation concepts analyzing the idea of museum, which still dominate. On the basis of the genesis of the museums in Osnabrück as the micro-historical environment, the study takes a closer look at the general history of both bourgeoisie and museum. In particular, it can be shown that, instead of an one-way influence from centre to periphery, the mutual interaction was and is far more distinct than has been recognized up to now. The analysis focuses on an anthropology of collecting, thereby clarifying the relation between the museum as an institution and the development of bourgeois identity. By showing the musealization and professionalization at that period to be a process of institutionalization of collecting, it becomes visible that the museum functioned as a space of museal socialization ("Museale Vergesellschaftung"), in which social borders could also be overcome. Furthermore, it illustrates that museums must be understood far more as "museum individuals", considering the strong individual shaping of museum collections, which originate in the perpetuation of life biographies.

description: This paper describes the design, fabrication and measured performance of a 4.9 to 6GHz Power Amplifier IC developed on a commercially available InGaP HBT process. It can address a number of applications including U-NII (US FCC), 802.11a, HiperLAN2, Japanese WLAN and cordless telephony. The amplifier was designed to operate from a 3.3V supply in either linear mode (backed off several dB from gain compression) or saturated mode (at an output power level of 0.5W). The quiescent current is kept low by an active bias circuit, and rises with increased input power to yield optimum efficiency in all modes. The active bias circuit also serves to extend the region of linear gain by appropriate dynamic control of the transistor’s base voltages. The amplifier requires a simple off-chip output matching network that can be tailored to satisfy a customer’s exact frequency/power requirements.

description: We consider the isoperimetric inequality on the class of high-dimensional isotropic convex bodies. We establish quantitative connections between two well-known open problems related to this inequality, namely, the thin shell conjecture, and the conjecture by Kannan, Lovasz, and Simonovits, showing that the corresponding optimal bounds are equivalent up to logarithmic factors. In particular we prove that, up to logarithmic factors, the minimal possible ratio between surface area and volume is attained on ellipsoids. We also show that a positive answer to the thin shell conjecture would imply an optimal dependence on the dimension in a certain formulation of the Brunn-Minkowski inequality. Our results rely on the construction of a stochastic localization scheme for log-concave measures.

description: Die vorliegende Dissertation gibt eine Gesamtinterpretation der Philosophie Michael Polanyis (1891-1976), die auf deren bislang verborgene fundamentalontologische Grunddimension zielt. Nach Polanyi ignoriert und überspringt jede Art von wissenschaftlicher Reduktion der Wirklichkeit ein vorwissenschaftliches Vorwissen des Menschen, das Polanyi in umfangreichen Detailerörterungen immer wieder konkret nachweist (Laplace, Kopernikus, DNA). Auch die modernste Wissenschaft hat dieses Vorwissen und den ihm entsprechenden Realitätsbereich zur Grundlage. Zu Recht identifiziert Polanyi dieses Vorwissen um die Wirklichkeit im weitesten Sinne mit dem "In-der-Welt-sein" Heideggers. Trotz interner Schwierigkeiten, die mit seinem bewusstseinstheoretischen Ansatz zu tun haben, geht die Intention Polanyis auf einen grundlegenden Realitätskontakt, den der Mensch hat und der den Boden abgibt für alle wahren Sätze über die Realität. Die Rückbesinnung auf diese nicht negierbare, sondern lediglich ignorierbare Form der Wahrheit kann dem Menschen die Fülle von Sinn und Wahrheit, die die Welt zu bieten hat und die nicht nur in der Wissenschaft, sondern auch in Kunst, Literatur, Musik und Religion ihren Ausdruck findet, wieder neu zugänglich machen. Polanyi eröffnet damit eine neue und aussichtsreiche Perspektive für das Philosophieren und Leben unter den Bedingungen der wissenschaftlich-technischen Zivilisation des 21. Jahrhunderts.
description: This dissertation gives a comprehensive interpretation of the philosophy of the british-hungarian philosopher Michael Polanyi (1891-1976). It shows that the so far hidden basic dimension of this philosophy is a fundamental-ontological one. According to Polanyi every kind of scientific reduction of reality ignores and omits a prescientific foreknowledge of man. Polanyi gives evidence for this foreknowledge in extensive and scientifically detailed arguments (Laplace, Copernicus, DNA). Even the most modern science is based on this foreknowledge and the reality corresponding to it. Polanyi rightly identifies this foreknowledge of reality with Heidegger's "being-in-the-world". Even if there are internal difficulties according to Polanyi's overestimation of consciousness, Polanyi intends a fundamental contact with reality, which man has and which is the foundation for every true sentence about reality. By reconsideration of this irrefutable, but ignorable type of truth man has the chance to open newly his world with all its abundant meaning and truth, not only in science, but also in art, literature, music and religion. A new and promising perspective for thinking and living under the conditions of the scientific civilisation of the 21st century is opened thereby by Polanyi.

Urban dwellers and neighborhood nature : exploring urban residents' connection to place, community, and environment
Creators: name: Church, Sarah P.
Publisher: name: University of British Columbia
Year: 2013

description: Urban residents, in part due to issues of urban form and lifestyle choice, have become both physically and cognitively disconnected from the environment and natural processes – a disconnection that has contributed to decisions that have led to over consumption of natural resources and degradation of Earth. The form of the built environment has contributed to this separation, with city development embedded within infrastructures of concrete and pavement. Further, there is little attention paid to smaller scale integration of nature at the neighborhood level that might allow for frequent resident contact and activity. Today, whether in growth or decline, cities are faced with regulatory obligations and crumbling infrastructure. These issues are compounded by the pressing need to address sustainable development and resilience in the face of uncertainty around climate change and the need for reduced oil use. Incremental urban restructuring of neighborhoods through planning and designing to the specifics of local ecology (place-based design) has the potential to restore a balance between urban areas and natural systems. I therefore studied how urban residents perceive and interact with these systems in order to answer the question: How does active involvement in Portland’s Tabor to the River watershed health program foster place-based awareness and environmental learning? This dissertation is an exploratory qualitative case study undertaken in Portland, Oregon in which I conducted 42 semi-structured interviews of community members and 14 experts. I explored how urban nature and sustainable stormwater infrastructure in the city is seen, perceived, and experienced by urban residents, and how these perceptions influence a human connection to nature and local environmental knowledge. My analysis found that in order to address a human connection to nature and influence environmental learning, the following aspects of urban retrofit should be considered: 1) Integrate a foundation of nature in the city for everyday life; 2) Incorporate multiple scales and types of nature for multiple experiences; 3) Ensure access to nature through walking and cycling; 4) Provide opportunities for hands on work in nature and personal control of space.

On the complexity of strongly connected components in directed hypergraphs
Creators: name: Allamigeon, Xavier
Publisher: name: arXiv
Year: 2011
Subjects: subject: Data Structures and Algorithms (cs.DS)
subject: FOS: Computer and information sciences

description: We study the complexity of some algorithmic problems on directed hypergraphs and their strongly connected components (SCCs). The main contribution is an almost linear time algorithm computing the terminal strongly connected components (i.e. SCCs which do not reach any components but themselves). "Almost linear" here means that the complexity of the algorithm is linear in the size of the hypergraph up to a factor alpha(n), where alpha is the inverse of Ackermann function, and n is the number of vertices. Our motivation to study this problem arises from a recent application of directed hypergraphs to computational tropical geometry. We also discuss the problem of computing all SCCs. We establish a superlinear lower bound on the size of the transitive reduction of the reachability relation in directed hypergraphs, showing that it is combinatorially more complex than in directed graphs. Besides, we prove a linear time reduction from the well-studied problem of finding all minimal sets among a given family to the problem of computing the SCCs. Only subquadratic time algorithms are known for the former problem. These results strongly suggest that the problem of computing the SCCs is harder in directed hypergraphs than in directed graphs.

description: In dieser retrospektiven Studie wurden über einen Zeitraum von 5 Jahren 278 Zähne von 250 Patienten untersucht. Ziel war es, die Erfolgsrate der direkten Überkappungen in Abhängigkeit verschiedener Parameter, wie Alter, Geschlecht oder Zahntyp zu bestimmen. Das verwendete Überkappungsmaterial war Dycal®. Wir ermittelten eine Erfolgsrate von 67%. 33% waren als Misserfolg zu werten. Die meisten Überkappungen wurden in der Altersklasse 21-30 Jahre durchgeführt (43,2%). Die 6-Jahr- Molaren wurden sowohl beim männlichen, als auch beim weiblichen Geschlecht am häufigsten behandelt, wiesen aber auch die häufigsten Misserfolge auf. Im Vergleich wurden im Oberkiefer 59% der direkten Überkappungen durchgeführt im Unterkiefer 41%. Die meisten Misserfolge (61%) traten innerhalb der ersten 6 Monate nach einer direkten Überkappung auf, als Mittelwert ergaben sich 55 Tage. Die Erfolgsrate nahm vom Front- zum Seitenzahnbereich hin ab. Es ließen sich in keinem der getesteten Fälle signifikante Abhängigkeiten darstellen. P war in jedem der getesteten Fälle > 0,05.
description: In this retrospective study 278 teeth from 250 patients were followed up over 5 years in 2003. The aim was to find out the success rate of direct pulp cappings in subject to age, gender or the typ of tooth. The capping material which was used was Dycal®. We found a success rate of 67%. 33% were failure. Most direct pulp cappings were carried out in the age group 21- 30 years (43,2%). Both, male and female gender, the 6- year- molars were the most frequently treated teeth. They also showed the highest failure rate. In comparision 59% of all treatment have been carried out in the maxilla teeth, 41% in the mandible teeth. Most direct pulp cappings failed during the first 6 month after treatment, the mean was 55 days. The success rate was decreasing from the anterior teeth to the posterior teeth. There could´t be found any significant dependence between all tested cases. P was always > 0,05.
The Incidence and cost of job loss in the ukrainian labor market

Subjects: SECS-P/01 Economia politica

description: We examine the effects of economic transition on the pattern and costs of worker
displacement in Ukraine, using the Ukrainian Longitudinal Monitoring Survey (ULMS) for
the years 1992 to 2002. Displacement rates in the Ukrainian labor market average between 3.4
and 4.8 percent of employment, roughly in line with levels typically observed in several
Western economies, but considerably larger than in Russia. The characteristics of displaced
workers are similar to those displaced in the West, in so far as displacement is concentrated
on the less skilled. Around one third of displaced workers find re-employment immediately
while the majority continues into long-term non-employment. The wage costs of displacement
for the sub-sample of displaced workers do not seem to be large. The main cost for displaced
workers in Ukraine consists in the extremely long non-employment spell that the average
worker experiences after layoff.
Semi-classical description of near-field driven attosecond photoemission from nanostructures
Creators: name: Seiffert, Lennart
Publisher: name: Universität Rostock
Year: 2018
Subjects: subject: 530 Physics

description: Exciting nanostructures with ultrashort laser pulses enables to generate strongly enhanced near-fields. Adjusting their evolution on nanometer length- and attosecond timescales allows precise control of the near-field driven electron motion and constitutes a key challenge for realizing ultrafast light-driven nanoelectronics. This thesis explores near-field mediated attosecond electron dynamics theoretically to develop so far lacking physical pictures for explaining recent experiments. Thereto, the light-matter interaction is modeled via classical, semi-classical and quantum simulations.

description: We prove existence and uniqueness of a viscosity solution of the Dirichlet problem related to the prescribed  Levi mean curvature equation, under suitable assumptions on the boundary data and on the Levi curvature of the domain. We also show that such a solution is Lipschitz continuous by proving that it is the uniform limit of a sequence of classical solutions of elliptic problems and by building Lipschitz continuous barriers.
Location in a vertically differentiated industry

Subjects: SECS-P/06 Economia applicata

description: We analyze a two-stage game in a vertically differentiated duopoly with
two regions which can differ for the willingness to pay of their consumers
or for the market size; firms sequentially choose to settle in one region
and then simultaneously compete in prices, selling their products both
on the local market and on the foreigner one by exporting them at a fixed
cost. We study how strategic interaction influences firms’ location choices
and we show that the decision whether to agglomerate or not crucially
depends on the extent of regions’ asymmetries, but, counter intuitively,
there are parametric regions in which the model predicts that the leader
(the first firm choosing location) settles either in the poorer or in the
smaller region, leaving the other one to the follower. Welfare analysis
completes the paper.
Dynamic oligopoly à la Stackelberg

description: I investigate a dynamic oligopoly game where firms enter simultaneously
but compete hierarchically à la Stackelberg at each instant over time. They
accumulate capacity through costly investment, with capital acumulation
dynamics being affected by an additive shock the mean and variance of which
are known. The main findings are the following. First, the Stackelberg
game is uncontrollable by the leader; hence, it is time consistent. Second,
the leaders invest more than the followers; as a result, in steady state, the
leaders’ capacity and profits are larger than the followers’. Therefore, the
present analysis does not confirm Gibrat’s Law, since the individual growth
rate is determined by the timing of moves.

Quantum disorder in the spatially completely anisotropic triangular lattice I: Heisenberg $S=1/2$ antiferromagnet

description: Spin liquids occuring in 2D frustrated spin systems were initially assumed to appear at strongest frustration, but evidence grows that they more likely intervene at transitions between two different types of order. To identify if this is more general, we here analyze a generalization of the spatially anisotropic triangular lattice (SATL) with antiferromagnetic Heisenberg interactions, the spatially \emph{completely} anisotropic triangular lattice (SCATL). Using Takahashi's modified spin-wave theory, complemented by exact diagonalizations, we find indications that indeed different kinds of order are always separated by disordered phases. Our results further suggest that two gapped non-magnetic phases, identified as distinct in the SATL, are actually continuously connected via the additional anisotropy of the SCATL. Finally, measurements on several materials found magnetic long-range order where calculations on the SATL predict disordered behavior. Our results suggest a simple explanation through the additional anisotropy of the SCATL, which locates the corresponding parameter values in ordered phases. The studied model might therefore not only yield fundamental insight into quantum disordered phases, but should also be relevant for experiments on the quest for spin liquids.

description: We study the strategic interaction between two firms competing in quantites
which decide whether exporting into each other market. The product is
homogeneous and production entails constant returns to scale. Scope effects
are present. By dealing with two types of trade costs, namely per unit and ad
valorem trade costs, we characterize the set of Nash equilibria showing that one
way trade is a possible outcome of the trade game. In particular, despite the
assumption on symmetry between firms, unilateral trade arises provided trade
costs are sufficiently high. The private incentives towards one way trade are
then compared with the social ones.
Incoerenza dinamica ed autocontrollo:
proposta per un'analisi interdisciplinare

Subjects: SECS-P/06 Economia applicata

description: In the last 25 years, a vast empirical literature has seriously chal-
lenged many assumptions on which the standard microeconomic approach
is based. Inspired by this evidence, behavioural economics suggests that a
research program that integrates the economic, psychological and neuro-
scientific literature can provide a theory of human decision-making with
stronger descriptive, predictive and normative power. This interdisci-
plinary approach does not necessarily imply abandoning the neoclassical
modelling tools and losing analytical tractability. As an example, the evo-
lution of the economic theory on intertemporal choice is presented, show-
ing that some standard economic assumptions can be viewed as special
cases in which self-control and dynamic consistency are always guaran-
teed.
