description: A new gate process for the realization of ultra short gate HEMT on InP is presented. In this technology, the top of the gate is deposited on a Si3N4 layer. This gate process leads to small footprints, mechanically strong devices and good yield. Using this gate technology, HEMT with high Ft were realized and characterized. The influence of the Si3N4 removing was also investigated.

Limits to the fraction of high-energy photon emitting gamma-ray bursts

Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: After almost 4 years of operation, the two instruments onboard the Fermi Gamma-ray Space Telescope have shown that the number of gamma-ray bursts with high energy photon emission above 100 MeV cannot exceed roughly 9% of the total number of all such events, at least at the present detection limits. In a recent paper (Zheng et al. 2012c), we found that GRBs with photons detected in the Large Area Telescope (LAT) have a surprisingly broad distribution with respect to the photon number above background. Extrapolation of our empirical fit to numbers of photons below our quoted detection limit suggests that the overall rate of such events could be determined by standard image co-adding techniques. In this case, we have taken advantage of the excellent angular resolution of the Swift mission to provide accurate reference points for 79 GRB events which have eluded any previous correlations with high energy photons. We find a small but significant signal. Guided by the power law fit obtained previously for the number distribution of GRBs, the data suggests that only a small fraction of GRBs are sources of high energy photons.

description: A quarant’anni dalla sua introduzione, la curva di Phillips riveste ancora un ruolo importante negli studi applicati, nonostante le critiche cui è stata sottoposta dalla successiva letteratura. In questo lavoro, utilizzando tecniche di modellazione econometrica di serie storiche non stazionarie per l’Italia dal dopoguerra ad oggi, si evidenzia la stabilità di una relazione di lungo periodo fra il tasso di variazione del salario reale e il tasso di disoccupazione; questo risultato è robusto all’uso di stimatori alternativi. Nel breve periodo si propone un modello interpretativo caratterizzato da un meccanismo non lineare di correzione dell’errore.

description: This paper analyzes the stochastic convergence in per capita income levels among the current G-7 over the period 1900-89. We show that, in the presence of possible structural breaks, the strong condition of stationary pair-wise differences between per capita GDP holds in many more cases than generally supposed. However, it occurs more frequently in the first part of the time sample than in the second one.
A world like ours : gay men in Japanese novels and films, 1989-2007
Creators: name: Hall, Nicholas James
Publisher: name: University of British Columbia
Year: 2013

description: This dissertation examines representations of gay men in contemporary Japanese novels and films produced from around the beginning of the 1990s so-called gay boom era to the present day. Although these were produced in Japanese and for the Japanese market, and reflect contemporary Japan’s social, cultural and political milieu, I argue that they not only articulate the concerns and desires of gay men and (other queer people) in Japan, but also that they reflect a transnational global gay culture and identity. The study focuses on the work of current Japanese writers and directors while taking into account a broad, historical view of male-male eroticism in Japan from the Edo era to the present. It addresses such issues as whether there can be said to be a Japanese gay identity; the circulation of gay culture across international borders in the modern period; and issues of representation of gay men in mainstream popular culture products. As has been pointed out by various scholars, many mainstream Japanese representations of LGBT people are troubling, whether because they represent “tourism”—they are made for straight audiences whose pleasure comes from being titillated by watching the exotic Others portrayed in them—or because they are made by and for a female audience and have little connection with the lives and experiences of real gay men, or because they circulate outside Japan and are taken as realistic representations by non-Japanese audiences. In this dissertation I argue that positive, supportive, indeed overtly political messages can be found, even in texts with problematical representations. I show that, over the nearly twenty year period covered by the novels and films I study, it is possible to discern a tendency towards less stereotyped, and more overtly political, portrayals. The novels and films I discuss in this dissertation represent a disparate range of genres, producers, and representations, and characters who are straight, gay, bisexual, transgender and transsexual. Yet all have in common the universal themes of overcoming or becoming, ranging from journeys to coming out, growing up, and finding the self to stories of triumphing over homophobia and prevailing over discrimination.

description: The observation that concepts from quantum information has generated many alternative indicators of quantum phase transitions hints that quantum phase transitions possess operational significance with respect to the processing of quantum information. Yet, studies on whether such transitions lead to quantum phases that differ in their capacity to process information remain limited. Here We show that there exist quantum phase transitions that cause a distinct qualitative change in our ability to simulate certain quantum systems under perturbation of an external field by local operations and classical communication. In particular, we show that in certain quantum phases of the XY model, adiabatic perturbations of the external magnetic field can be simulated by local spin operations, whereas the resulting effect within other phases results in coherent non-local interactions. We discuss the potential implications to adiabatic quantum computation, where a computational advantage exists only when adiabatic perturbation results in coherent multi-body interactions.

description: The existence of a pure-strategy subgame perfect equilibrium in qualities and prices is investigated in a duopoly model of vertical differentiation where quality improvements require a quadratic variable cost. The alternative cases of partial and full market coverage are considered. It is shown that there exists a parameter range where the incentive to decrease differentiation arises for the high-quality firm, preventing firms to reach a pure-strategy duopoly equilibrium.

description: Immuntherapie mit Tumorantigen-beladenen dendritischen Zellen (DCs) ist ein neuer Ansatz zur Krebsbehandlung. In dieser Studie wurde die Transfektion von DCs mit RNA Replikons als Methode etabliert, um Tumorantigene in DCs zu exprimieren und cross-priming zu induzieren. Es wurden Replikons konstruiert die Fragmente des Tumorantigens Her2 oder Interleukin 12 kodieren. Die Mäuse wurden mit Replikon-transfizierten DCs vakziniert und mit Her2-exprimierenden Tumorzellen injiziert (tumor challenge). Die Vakzinierung mit Replikon-beladenen DCs führte zu signifikant kleineren Tumoren im Vergleich zur pseudovakzinierten Kontrollgruppe. Des Weitern blieben bis zu 75% der vakzinierten Mäuse ohne Tumore. Die detaillierte Analyse der Immunantwort ergab eine Korrelation zwischen anti-Tumoreffekt und durch cross-priming induzierter T-Zellantwort. Die Depletion von CD4+ oder CD8+ Zellen vor der tumor challenge hob den anti-Tumoreffekt auf. Außerdem wurde nachgewiesen, dass CD8+ T-Zellen durch cross-priming induziert wurden. Insgesamt stellen diese Ergebnisse das Potential von cross-priming für Vakzinierungsstrategien heraus. Dieser Ansatz könnte als sicheres und effizientes Mittel für das Einführen eines Tumorantigens in DCs zum Einsatz kommen.
An Optimal Partnership Search Model: Theoretical Implications for the Europartenariat Event

Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 1998
Subjects: SECS-P/01 Economia politica

description: A theoretical search model applied to collaboration among firms with a public authority as an intermediate is the primary issue of this paper. Specifically, we consider the Europartenariat event since it represents a good opportunity to study a problem of interaction between the decision to search a collaboration and the exchange of information involved in a bargaining process. Search costs play a central role in this framework. We show the optimality of a strategy as to the number of contacts with host companies in a problem of dynamic programming. Precisely, solutions in a search model with the presence of fixed and quadratic costs are derived in terms of an optimal threshold number of contacts and of an optimal interval of the number of contacts, respectively. For the case of fixed costs, we find that the minimum number of contacts for which the firm accepts to participate is negatively related to the expected profit and to the probability of contacting one firm with a common project of collaboration. This is confirmed by a simulation. In the quadratic cost hypothesis we investigate learning phenomena and revelation of private information.

description: For many types of graphs, criteria have been discovered that give necessary and sufficient conditions for an integer sequence to be the degree sequence of such a graph. These criteria tend to take the form of a set of inequalities, and in the case of the Erdős-Gallai criterion (for simple undirected graphs) and the Gale-Ryser criterion (for bipartite graphs), it has been shown that the number of inequalities that must be checked can be reduced significantly. We show that similar reductions hold for the corresponding criteria for many other types of graphs, including bipartite r-multigraphs, bipartite graphs with structural edges, directed graphs, r-multigraphs, and tournaments. We also prove a reduction for imbalance sequences.

description: Excerpts from the report: These are findings of a study that originated with requests by members of the Michigan apple-packing industry for information on cost-volume relationships in apple packing. Many small volume apple packers must decide whether they are going to continue operating at their present scale, expand their operations, sell their apples field-run, or combine operations with other packers. This study provides information for apple packers to use in planning future plant operations. The principal objective of the study was to determine the cost-volume relationships in synthetically constructed apple-packing plants operating under conditions representative of those found in Michigan. Intermediate objectives included the determination of least-cost packing methods and labor requirements for the jobs in apple-packing plants. The economic-engineering method of cost analysis was used in this study. Labor utilization and equipment data for the analysis were obtained from observations taken in 14 Michigan apple-packing plants.

description: It is well known that during homology recognition and strand exchange the double stranded DNA (dsDNA) in DNA/RecA filaments is highly extended, but the functional role of the extension has been unclear. We present an analytical model that calculates the distribution of tension in the extended dsDNA during strand exchange. The model suggests that the binding of additional dsDNA base pairs to the DNA/RecA filament alters the tension in dsDNA that was already bound to the filament, resulting in a non-linear increase in the mechanical energy as a function of the number of bound base pairs. This collective mechanical response may promote homology stringency and underlie unexplained experimental results.

description: The composite spectra of quasars are widely used as templates for redshift determination, as well as for measurements of the mean transmission in Lyα-forest studies, and for investigation of general spectral properties of quasars. Possibility of composite spectra utilisation in these fields is related to remarkable similarity of quasar spectra in UV-optical range. But despite of general similarity in spectral shapes, they differ in several parameters, one of which is the spectral index. In the present paper we study the possible effects, related to neglect of this difference. We compiled 16 composite spectra from subsamples of individual SDSS DR7 quasar spectra with different spectral indices α_λwithin the wavelength range 1270-1480 Å, and show that (i) the redshifts measured for a test sample of high signal-to-noise ratio quasar spectra using these composites as templates appear to be systematically higher than those calculated with a traditional template, compiled from spectra with different α_λ, with 1.5 times smaller errors in the former case; (ii) the difference in α_λin individual spectra used for compilation of composites can yield the mean transmission uncertainty up to 20%; (iii) a number of emission lines indistinguishable in ordinary composites, but seen in individual high-resolution spectra, can be detected in such composites. It is also shown, that there is no dependence of α_λon quasar luminosity in SDSS u, g, r and i bands, and monochromatic luminosity at 1450 Å.

Year: 1999
Subjects: SECS-P/01 Economia politica

description: In this paper we develop an endogenous growth model of open economies, where countries differ with respect to the quality of property rights. Within this context, we analyze two types of reforms. First, we look at growth and welfare effects of removing capital controls, given the degree of property rights protection. Second, we endogenize the quality of property rights and study the political support for a reform aimed at improving it. We show that, in countries where property rights are poorly protected, the liberalization of capital movements, that may or may not foster economic growth in the shortrun, eliminates the possibility of sustained physical capital accumulation. Nevertheless, the removal of capital controls may benefit the agents alive at the time of liberalization, leaving a burden for future generations. Ceteris paribus, the political support for a reform of property rights will be stronger in the closed economy than in the open economy.

Die Ncl. n. facialis und n. abducentis wurden anhand von Kresylviolett gefärbten Schnitten identifiziert, die Fasern des N. facialis anhand von mit Silbernitrat fixierten. Alle Schnitte wurden digitalisiert, die Volumes Of Interest unter mikroskopischer Kontrolle segmentiert und dreidimensional rekonstruiert. Ergebnisse: Das Modell stellt die komplexe Natur der räumlichen Beziehung zwischen den untersuchten Strukturen dar. Damit kann die räumliche Vorstellung von der Anatomie des Hirnstammes unterstützt und das funktionserhaltende Operieren erleichtert werden.
description: Objective: To develop a 3D-model of the complex consisting of the facial nucleus, the nucleus nervi abducentis and the facial nerve fibers to get a better spatial understanding of this functionally important complex and thus facilitate intraoperative orientation during neurosurgical procedures around the brainstem. Methods: One human brainstem was cut into 50µm thick slices after paraffin fixation. For identifying the motor nuclei of the facial and abducens nerve cresylviolet-stained slices were used, for the fibers we used silver nitrate-fixed slices. All slices were digitized, volumes of interest were segmented on the computer platform with microscopic verification. Segmented volumes were reconstructed three-dimensionally. Results: 3D-reconstruction provided a model representing the complex nature of the spatial relationship between facial nucleus and its fibers. Thus, the surgeon`s idea of brainstem anatomy might be supported and the preservation of nerve function facilitated.

Both the characterizations are purely combinatorial and are expressed in terms of the highest weights of V. In particular, we show that Sp(2r) (with r > 0) is the unique non-adjoint simple group which admits a simple smooth compactification.

description: We analyse optimal penal codes in both Bertrand and Cournot supergames with product differentiation. We prove that the relationship between optimal punishments and the security level (individually rational discounted profit stream) depends critically on the degree of supermodularity in the stage game, using a linear duopoly supergame with product differentiation. The security level in the punishment phase is reached only under extreme supermodularity, i.e., when products are perfect substitutes and firms are price setters. Finally, we show that Abreu's rule cannot be implemented under Cournot behaviour and strong demand complementarity between products.
Synthesis, structure, and reactivity of early transition metal precatalysts bearing (N,O)-chelating ligands
Creators: name: Payne, Philippa Robyn
Publisher: name: University of British Columbia
Year: 2014

description: The synthesis, structure, and reactivity of early transition metal complexes containing (N,O)-chelating ancillary ligands are described. The ligands investigated include ureates, pyridonates, amidates, and sulfonamidates. These related ligands generate four-membered metallacycles when bound to the metal center in a κ²-(N,O) fashion. The zirconium and tantalum complexes have been examined in terms of their activity and selectivity as precatalyst systems for hydroamination or hydroaminoalkylation. A chiral cyclic ureate ligand has been synthesized from enantiopure L-valine for application in zirconium-catalyzed asymmetric hydroamination of aminoalkenes. Chiral zirconium complexes, prepared in situ from two equivalents of the urea proligand and tetrakis(dimethylamido) zirconium, promote the formation of pyrrolidines and piperidines in up to 12% ee. Isolation of an asymmetric bimetallic zirconium complex containing three bridging ureate ligands confirms that ligand redistribution occurs in solution and is most likely responsible for the low enantioselectivities. Mechanistic investigations focusing on the hydroaminoalkylation reactivity promoted by a bis(pyridonate) bis(dimethylamido) zirconium precatalyst expose a complex catalytic system in solution. Stoichiometric investigations reveal the formation of polymetallic complexes upon addition of primary amines. The kinetic and stoichiometric investigations are most consistent with a bimetallic catalytically active species. A series of mono(amidate) tantalum amido complexes with varying steric and electronic properties have been synthesized via protonolysis. Solid-state and solution-phase characterization indicate that the amidate substituents influence the observed binding mode of the ligand. Salt metathesis and protonolysis routes to the synthesis of mixed tantalum chloro amidate complexes are investigated. Sulfonamide proligands react with pentakis(dimethylamido) tantalum to generate well-defined monomeric complexes containing a κ²-(N,O) bound sulfonamidate. The hemilabile (N,O)-chelating amidate ligands, which generate four-membered metallacycles, are the most active of the precatalysts examined for the intermolecular hydroaminoalkylation of terminal olefins with secondary amines. The substrate scope of a mono(amidate) tetrakis(dimethylamido) tantalum complex has been examined for the α-alkylation of unprotected piperidine, piperazine, and azepane N-heterocyclic amines. The lack of reactivity with pyrrolidine substrates is examined by quantum chemical calculations and isotopic labeling studies. Two (N,O)-chelating ureate ligands are also successful ancillary ligands for this transformation and, with a C₁-symmetric chiral ureate complex, enantioselective α-alkylation of piperidine is observed.

Subjects: SECS-P/01 Economia politica

description: We model the non-cooperative choice between quantity and price in order to stabilize collusion, through two meta-games where each firm alternatively considers its payoff in the market supergame as directly related to its own or the rival's ability to collude. In the first setting, (i) if cartel profits are evenly split, firms collude in prices irrespective of the degree of differentiation, so that initially a Prisoners' Dilemma is observed, while for very close substitutes the outcome is Pareto-efficient; (ii) if Nash bargaining is adopted, price setting is dominant when substitutability is low, while no dominant strategy exists when substitutability is high, and the game has two asymmetric equilibria. In the second setting, the Nash equilibrium is unique and Pareto-e±cient for the most part of the substitutability range, while again two asymmetric equilibria obtain when products are very close substitutes.

description: The financial performance of 240 farms in a drought-affected agricultural region of Australia is analysed. The decadal study period included some years of widespread drought, as well as years with only subregional droughts or no drought. Some droughts created larger adverse financial impacts than others. Mostly, the more droughts farms experienced, the worse was their financial performance relative to farms within the same quantile of farm performance. Despite the incidence of drought, by the end of the decade, almost all the farm businesses were wealthier from increasing their farm size and becoming more crop dominant. Unexpectedly, consecutive years of drought had a significant positive effect on the operating profit per hectare and retained profit per hectare of farms in a majority of their respective quantiles. Many farms that experienced consecutive drought were forced to make structural changes, shifting away from livestock production towards additional cropping. These structural changes boosted farm performance over the decade. The incidence of drought affected some measures of farm performance differently whilst others were affected similarly. Understanding these metrics of farm performance and the structural changes underway in an agricultural region helps form a more complete view of drought impacts.

description: In the field of telecommunications, the applications for GaAs MMIC's beyond 2000 will include today's drivers such as Cellular and Portable Telephones, Direct Broadcast Systems and CATV distribution, but also the emerging markets of multimedia satellite communications, broadband Wireless Services, and high bit rate optical fibre systems. These latter systems use millimetre wave carrier frequencies, typically ranging from 10 GHz to 80 GHz. The full paper will look at the requirements which have shaped the Philips' GaAs technologies available today as well as what will be required for the future. Examples will be given of both the system requirement, circuit solution and the technology push.

description: We propose a model in which a recently reported modulation in the decay of the hydrogenlike ions ${}^{140}$Pr$^{\, 58 +}$, ${}^{142}$Pm$^{\, 60 +}$ and ${}^{122}$I$^{\, 52 +}$ arises from the coupling of rotation to the spin of electron and nucleus. The model shows that the spin-spin coupling of electron and nucleus does not contribute to the modulation and predicts that the anomaly cannot be observed if the motion of the ions is rectilinear, or if the ions are stopped in a target. It also supports the notion that the modulation frequency is proportional to the inverse of the atomic mass.

description: Funkenerosionsanlagen zählen zu den problematischsten hochfrequenten Störquellen im Industriebereich. Die vom Generator gelieferten steilflankigen Stromimpulse weisen bereits einen hohen Oberschwingungsgehalt auf. Hinzu kommen breitbandige stochastische Signalanteile durch den Funken selbst. Die Steuerelektronik steht im Signalaustausch mit der Leistungselektronik und den übrigen Anlagenkomponenten. Sie wird auf engstem Raum mit der Leistungselektronik betrieben. So ist schon die Sicherstellung der internen EMV eine Herausforderung. Der Maschinenaufbau bildet unvermeidlich eine effektive Antenne, zudem breiten sich Störungen leitungsgebunden über das Versorgungsnetz aus. Ausgeprägte Funkstörungen können ebenso die Folge sein wie Funktionsstörungen benachbarter Geräte und Anlagen. Der Gewährleistung der externen EMV kommt daher ebenfalls große Bedeutung zu. Ein Ziel der Arbeit ist, einen Beitrag zur selten behandelten Problematik der EMV von Funkenerosionsanlagen zu leisten. Bei EMV-Untersuchungen im Industriebereich wird oftmals eine rein experimentelle Herangehensweise gewählt; die Funkenerosionsanlage soll daher hier zugleich als komplexes Beispielobjekt dienen, um Brücken zwischen theoretischer Beschreibung, Simulation und experimentellem Vorgehen zu erarbeiten. In starkem Maße werden Modellbeschreibungen genutzt, wobei stets auf ingenieurtechnische Anschaulichkeit geachtet wird. Die leitungsgebundene Signalausbreitung im Generator wird an Hand eines schrittweise aufgebauten Ersatzschaltbildes analysiert. Die auftretenden Gleichtaktströme erweisen sich in besonderem Maße als kritisch und werden in das Modell einbezogen. Durch Vergleichsmessungen bei kurzgeschlossenem Funkenspalt und beim Erodieren wird der Signaleinfluß durch den Funken deutlich. Die Strahlungsmechanismen werden an einem ebenfalls schrittweise erstellten Feldsimulationsmodell untersucht. Zum Vergleich werden Strahler-Grundstrukturen herangezogen, die auf einfachste Weise wertvolle Abschätzungen erlauben. Es wird gezeigt, wie sich aus den Ergebnissen Maßnahmen zur Sicherstellung der EMV ableiten lassen.

description: Excerpts from the report: This publication is based on a large-scale study of the use of malathion-treated raisin-drying trays as a means of protecting raisins from insects during the periods of drying and storage. The tests also included laboratory bioassay tests and microanalyses. The results of the 1962-63 study are reported in three parts. In part I, the levels of malathion residue and the insect populations were determined and taste tests were made. In part II, bioassay studies evaluated the effectiveness of the different levels of malathion residue under controlled laboratory conditions. In Part III, insect and insect fragment counts were determined by a laboratory washing process (microanalysis).
The truncated K-Moment problem for closure of open sets

description: We solve the truncated K-moment problem when $K\subseteq R^n$ is the closure of a, not necessarily bounded, open set (which includes the important cases $K=R^n$ and $K=R^n_+$). That is, we completely characterize the interior of the convex cone of finite sequences that have a representing measure on $K\subseteq R^n$. It is in fact the domain of the Legendre-Fenchel transform associated with a certain convex function. And so in this context, detecting whether a sequence is in the interior of this cone reduces to solving a finite-dimensional convex optimization problem. This latter problem is related to maximum entropy methods for approximating an unknown density from knowing only finitely many of its moments. Interestingly, the proposed approach is essentially geometric and of independent interest, as it also addresses the abstract problem of characterizing the interior of a convex cone C which is the conical hull of a set continuously parametrized by a compact set $M\subset R^n$ or $M \subseteq S^{n-1}$, where $M$ is the closure of an open subset of $R^n$ (resp. $S^{n-1}$). As a by-product we also obtain a barrier function for the cone C.

description: Two new expansions for partial sums of Gauss' triangular and square numbers series are given. As a consequence, we derive a family of inequalities for the overpartition function $\bar{p}(n)$ and for the partition function $p_1(n)$ counting the partitions of $n$ with distinct odd parts. Some further inequalities for variations of partition function are proposed as conjectures.

description: GaAs components in MESFET, HEMT and HBT technology are a valuable supplement to traditional Si RF technologies and cover 15 to 20% of all RF applications. Their major application potential is in power amplifiers for mobile communication as well as WLAN and WLL transceiver circuits. Moreover, at MMW frequencies new applications like radio links, SATCOM and car distance radar support the introduction of GaAs hetero devices. Production quantities of about 100 million pcs and annual growth rates of about 30% clearly require large volume production strategies and cost positions well-known from Si counter­parts.
