description: The time-resolved spectral analysis of GRB090227B, made possible by the Fermi-GBM data, allows to identify in this source the missing link between the genuine short and long GRBs. Within the Fireshell model [...] we predict genuine short GRBs: bursts with the same inner engine of the long bursts but endowed with a severely low value of the Baryon load, B=(1.90+/-0.20)x10^{-5} #/cm^3. There is no evidence of beaming in the system. In view of the energetics and of the Baryon load of the source, as well as of the low interstellar medium and of the intrinsic time scale of the signal, we identify the GRB progenitor as a binary neutron star. From the recent progress in the theory of neutron stars, we obtain masses of the stars m_1=m_2=1.34M_Sun and their corresponding radii R_1=R_2=12.24km and thickness of their crusts ~0.47km, consistent with the above values of the Baryon load, of the energetics and of the time duration of the event.

Reforming the Personal Income Tax and the Family Allowance in Italy: a Proposal

Subjects: SECS-P/03 Scienza delle finanze

description: We illustrate a proposal to reform the personal income tax and the family allowance in Italy which aims at attaining a fair tax treatment of the family, laying emphasis on the redistributive processes in favour of large and poor households. Our proposal is based on a simplification of the tax rate schedule (with a reduction of income brackets) and a new design of the tax credits for dependents which implies the fiscal exemption of a sort of basic income, which is decreasing as the income of the household increases. The new scheme of supplementary tax credits for dependents, related to family income thresholds, would match the need to keep into account the economic conditions of the household with the need to avoid the abandonment of the definition of ability to pay on individual basis. The proposal also aims at attaining a closer integration between the personal income taxation and the family allowance, with a sizable revaluation of the amount of family allowances and its extension to self-employee. The distributional analysis, using the tax-benefit model DIRIMOD, shows a slight revenue loss and a significant increase, with respect to the 1995 system, in both the progressivity and the redistributive impact of the income tax. The distributional effects are even stronger if we keep into consideration the reformed system of family allowances.

The role of photoreceptor ABC transporter ABCA4 in retinal and lipid transport and Stargardt macular degeneration
Creators: name: Quazi, Faraz
Publisher: name: University of British Columbia
Year: 2013

description: ABCA4 is a member of the superfamily of ATP-binding cassette (ABC) transporters implicated in the clearance of retinoids from photoreceptor outer segments and associated with Stargardt macular degeneration. Stargardt patients display lipofuscin deposits and photoreceptor degeneration that invariably lead to the loss of central vision. In biochemical and knockout mice studies, ABCA4 has been implicated in the transport of N-retinylidene-PE, the Schiff base conjugate formed from all-trans retinal and phosphatidylethanolamine (PE). The principal challenge in assessing direction and transport has been impeded by the unstable hydrophobic nature of the proposed substrate. As part of this study, a novel biochemical transport assay was developed and used to show that ABCA4 actively flips N-retinylidene-PE from the lumen to the cytosolic side of membranes. This is the first mammalian ABC transporter shown to function as an importer. 11-cis retinal delivered in excess to photoreceptors is a defining cause of lipofuscin/A2E formation. Purified ABCA4 transports 11-cis retinylidene-PE. By HPLC analysis, 11-cis retinal also showed isomerization to all-trans retinal with PE present in discs. Thus, ABCA4 insures the complete removal of N-retinylidene-PE conjugates from the disc-lumen, thereby preventing accumulation of lipofuscin precursors including A2PE. Stargardt mutants which showed reduced functionality were rescued by allosteric enhancement of ATPase with dronedarone, an anti-arrhythmic drug, acting in concert with an increase in N-retinylidene-PE transport. Additionally, protein misfolding was selectively restored by 4-phenylbutyrate, a chemical chaperone. Genetic mutations in several ABCA subfamily transporters cause severe-inherited lipid disorders. The structure-function relationships underlying substrate specificity remain unclear. ABCA1 linked to Tangier disease has been implicated in the export of cholesterol and phospholipids to the apolipoproteinA-I acceptor by cell-based assays. In this study, biochemical analysis indicated that purified and reconstituted ABCA1 actively flipped phosphatidylcholine, phosphatidylserine, and sphingomyelin from the cytoplasmic to the lumenal side of membranes, while ABCA7 preferred phosphatidylserine. In contrast, ABCA4 transported PE in the reverse direction. Tangier and Stargardt mutants showed reduced lipid transport activities. This thesis demonstrates the importance of ABCA4 as a unique ABC importer, reports the first reconstitution of phospholipid flippase activity for ABCA transporters, and identifies several compounds as potential therapeutic drugs for Stargardt disease.

description: Die Aufgabenstellung dieser Arbeit basiert auf dem grundsätzlich vorhandenen Interesse an Möglichkeiten der Myokardprotektion nach vorhergehender Schädigung. Darauf bezugnehmend werden hier zwei vermeintliche Protektoren, die Reduktionsmittel Glutathion und Ascorbinsäure, auf ihre Potenz zur Kardioprotektion in vitro überprüft. Die sogenannte "Scavenger"-Funktion beider Reduktionsmittel ist dabei als Wirkmechanismus von hauptsächlichem Interesse. Untersucht werden im speziellen das kardioprotektive Potential der benannten Reduktionsmittel bei Schädigung der Herzpräparate durch Ischämie/Reperfusion sowie durch die Noxen Verapamil, Pentobarbital, Tetrachlorkohlenstoff und Kaliumionen-Überschuß. Es werden einfache Modelle (Langendorff-Herz, Vorhof-Aurikel-Präparat) verwandt, in denen Glutathion und Ascorbinsäure mit den unterschiedlichen Noxen in kombinierten Testreihen zur Reaktion gebracht werden. Es konnten dabei in keiner der durchgeführten Versuchsreihen signifikante Veränderungen der entsprechenden Parameter festgestellt werden, die auf karkoprotektive Effekte der Reduktionsmittel schließen lassen. Neben den Untersuchungsergebnissen steht der vorgegebene methodische Absatz dieser Arbeit als nicht optimal zur Diskussion.
description: This paper's topic is based on a general interest for possibilities of myocarditic protection after preceding impairment. In turn, two alleged protectors, the reducing agents glutathion and ascorbic acid are verified for their potential of cardio-vascular protection in vitro. The so-called "Scavenger"- function of both reducing agents is thereby as a mechanism of action of the paper's main interest. In particular, the cardioprotective potential of the reducing agents in the case of an impairment of the heart prepatation by ischaemia/reperfusion, as well as by the noxes verapamil, pentobarbital, tetrachloromethane and kalium ion surplus are investigated. Easy models (‘Langendorff-heart', atrium-auricle-preparation) are used, in order to combine glutathion and ascorbic acid with various noxes in combined experiments. None of these experiments resulted in the detection of significant changes of the appropriate parameter, which could trigger a conclusion of cardioprotective effects of the reducing agents. Besides those findings, this paper discusses the inappropriateness of the research's predetermined methodological approach.

description: The choice between quantity and price in order to stabilize collusion is modeled here. It is shown that this relocates the prisoners’ dilemma backwards, from the market stage to the stage where the market variable is chosen in order to sustain collusion, and where discount rates appear as the payoffs. Likewise, a prisoners’ dilemma arises also when both the market variable and the type of behavior (cooperative or non-cooperative) are simultaneously chosen.
Vertical Differentiation, Trade and Endogenous Common Standards

description: Different market settings are considered in a free trade environment, where firms can choose technology, quality, and price or quantity. The shape of competition in prices requires the intervention of governments, via a common antidumping policy, to make firms converge on the simultaneous equilibrium which is socially optimal. In the Cournot framework, the equilibria we obtain impinge upon the kind of precommitments undertaken by firms. The coincidence between firms' behaviour and social preference obtains either when competition is tough, since income is low, or when firms must compete in quantities in the market stage, since they cannot modify qualities. The spontaneous coordination over common standards has to be contrasted with both the case of a²uent consumers and Bertrand competition.

description: Die vorliegende Arbeit stellt eine allgemeine Untersuchung zu stochastischen Differentialinklusionen (SDI) dar. Es werden endlichdimensionale und unendlichdimensionale SDI des Typs dX(t) + A(t,X(t))dt + B(t,X(t))dW1(t) ... F(t,X(t))dt + G(t,X(t))dW2(t), X(0) = X0 betrachtet, wobei die Operatoren A, B einwertig und F, G mengenwertig sind.Für den Nachweis der Lösbarkeit werden unterschiedliche, bisher noch nicht auf SDI angewendete Methoden erarbeitet, je nach Art der Eigenschaften der mengenwertigen Abbildungen. Der Grundgedanke besteht dabei stets darin, die stochastischen Differentialinklusionen auf stochastische Differentialgleichungen über die Wahl von Selektoren zurückzuführen. In diesem Sinn sind SDI als Verallgemeinerung stochastischer Differentialgleichungen auffassbar.Im Fall endlichdimensionaler Inklusionen werden Existenzsätze für jegliche Kombination maximal-monotoner und Lipschitz-stetiger Drift- und Diffusionsterme mit Hilfe der Yosida-Approximation und entsprechender Selektionstheoreme bewiesen. Teilweise existieren hierfür eindeutige Lösungen.Der Hauptteil der Arbeit beschäftigt sich mit SDI auf Evolutionstripeln. Für Lipschitz-stetige mengenwertige Abbildungen führt das Galerkin-Verfahren zu Aussagen der Lösbarkeit und der Approximationsgüte.Mit der Methode von Ober- und Unterlösung ist es möglich, die Lösungsmenge von Inklusionen mit maximal-monotoner Drift und Diffusion einzuschließen. Auch hier werden Eindeutigkeitsresultate formuliert.Anhand von Beispielen aus der Praxis finden schließlich die formulierten Ergebnisse Anwendung.
description: This thesis deals with finite and infinite dimensional stochastic differential inclusions (SDI) like dX(t) + A(t,X(t))dt + B(t,X(t))dW1(t) ... F(t,X(t))dt + G(t,X(t))dW2(t), X(0) = X0with single-valued operators A, B and set-valued maps F, G.According to the properties of the set-valued maps we present several methods for proving existence. Basic idea is to substitute SDI by stochastic differential equations via certain selections of the set-valued maps. So SDI are considered as a generalization of stochastic differential equations.For finite dimensional SDI with maximal monotone or Lipschitz-continuous set-valued maps we prove existence by using Yosida approximations and selection theorems. Additionally unique solutions exist.In the main part of the thesis we concentrate on solving SDI on an evolution triple. The method of Galerkin is applied to the case of SDI with Lipschitz-continuous set-valued maps.Besides the existence we achieve conclusions of approximating the solution set.With the method of upper and lower solution it is possible to enclose the set of solutions for SDI with special maximal monotone drift and diffusion. Here we can also show the uniqueness of a solution.At least the results are completed by some examples.
Proteomic analysis of a dynamic Salmonella-host interactome
Creators: name: Brown, Lyda Mimi
Publisher: name: University of British Columbia
Year: 2013

description: Salmonella is capable of evading the host immune response by secreting virulence factors (effectors) that enter the host and interfere with critical cell signaling networks. Although many of the individual effector proteins have been well characterized by traditional biochemical methods, a shift towards global strategies would offer a system’s view of the intricate network of interactions (interactome) between the host and pathogen. Protein profiling across size exclusion chromatography with stable isotope labeled amino acids in cell culture (PCP-SILAC) is a recent proteomic method developed to characterize the composition of protein complexes with the advantages of being quantitative, capable of monitoring dynamic changes, and being completely tag and chemical cross-link free. This method was applied to study the dynamic changes of host protein complexes as a result of Salmonella infection. Analysis of dynamic PCP-SILAC proteins led to the hypothesis that host translational machinery was being targeted by Salmonella during infection. To test this hypothesis, a fluorescent assay was used to measure protein synthesis of cells infected with WT Salmonella versus control (non-infected cells). Results from the protein synthesis analysis showed a decrease in host translation, supporting our hypothesis that Salmonella targets host translational machinery. I addition to this novel finding, this work provides a rich resource of candidate host proteins that may be involved with Salmonella’s pathogenesis.

description: The consequences of free trade are investigated in an international duopoly under horizontal differentiation and convex transportation costs. It is shown that the smaller country may benefit from trade if it is sufficiently small to allow for a significant volume of exports by the domestic firm. On the contrary, the larger country never benefits from trade, since liberalization decreases the domestic firm’s profit more than it increases consumer surplus.
Automatische Flow Injection Analysis-Verfahren für die Lebensmittel-, Umwelt- und klinische Analytik

description: In the doctoral thesis new fluorimetric and fully automated flow injection analysis (FIA) procedures were described. These FIA procedures are based on the derivatization reaction of ammonia and reducing sulphur compounds with o-phthalaldehyde (OPA) and the fluorimetric detection of the generated isoindol derivates. A selective, fast reacting and totally aqueous OPA reagent was developed for the sensitive determination of ammonia/ammonium. The detection limit (DL) was 20 nM. This detection is combined with enzyme catalyzed conversion of ammonia releasing analytes. On this basis FIA procedures were developed for the determination of urea, creatin, creatinin, glutamate, glutamine, and lysine (DL 0.1-1.0 µM). A multichannel FIA set-up was constructed for the sequential determination of ammonia, creatin, creatinin and urea or of glutamate, glutamine and ammonia. The precise determination of ammonia releasing enzyme activities, e.g. of urease was implemented. This opened up a way to determine inhibitors of urease, e.g. Cu(II) and Ag(I) ions. By the in situ preparation of inverse OPA reagents by premixing of OPA and ammonium solutions highly sensitive detection procedures were implemented for the FIA determination of sulphite (DL 50 nM), sulphide (DL 800 nM) and thiols. The fluorimetric detection of thiocholine (DL 80 nM) can be applied for an automatic assay for acetylcholinesterase inhibitors. Acetylcholinesterase was immobilized on magentic microbeads. A FIA set-up with a magnetic separation and incubation cell was constructed and applied for the sensitive determination of carbofuran and paraoxon(DL 13.5 and 17.5 nM). The inverse OPA reagents could also be used for the determination of other polar thiols, e.g. reduced glutathione (DL 60 nM) and cysteine (DL 5 µM). A selective procedures was developed for the determination of reduced glutathione in the presence of dithiotreitol, cysteine, oxidized glutathione, cystine and methionine. Oxidized glutathione was determined after its reduction by dithiotreitol. Fully automated FIA immunoassays (FIIA) were developed on the basis of antibodies immobilized on magnetic microbeads and the magnetic separation. Atrazine, metolachlor, carbofuran and 2,4-dichlorphenoxyacetic acid were determined in the lower mgl-1 range (0.1). By the combination of the FIIA procedure with a solid phase extraction system (SPE) the detection limit of 2,4-dichlorphenoxyacetic acid could be improved 50-fold. SPE can be combined also with the FIA set-up for determination of acetylcholinesterase inhibitors (carbofuran and paraoxon) with the aim to shift the detection limit to lower concentrations about the factor 50 (DL 270 and 350 fM).

description: Bilinear R-parity violation (BRPV) provides the simplest intrinsically supersymmetric neutrino mass generation scheme. While neutrino mixing parameters can be probed in high energy accelerators, they are unfortunately not predicted by the theory. Here we propose a model based on the discrete flavor symmetry $A_4$ with a single R-parity violating parameter, leading to (i) correct Cabbibo mixing given by the Gatto-Sartori-Tonin formula, and a successful unification-like b-tau mass relation, and (ii) a correlation between the lepton mixing angles $θ_{13}$ and $θ_{23}$ in agreement with recent neutrino oscillation data, as well as a (nearly) massless neutrino, leading to absence of neutrinoless double beta decay.

Due to the built-in chiral symmetry, four of eight axial DAs are related to that for pions. Knowledge of these nonperturbative objects is important for phenomenological study of high-energy neutrino interactions and semileptonic decays of heavy quarks. We provide a code for evaluation of these DAs and an interpolation formula valid in the region Q^2 < 1 GeV^2.

The window of locational opportunity-concept

Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 1996
Subjects: SECS-P/01 Economia politica

description: This article aims to set out a theoretical concept, i.e. the Window of Locational Opportunity concept, which accounts for notions like indeterminacy, human agency and historical accidents when explaining the spatial pattern of newly emerging industries. We will state that their spatial formation does probably not reveal predictable tendencies of necessity and regularity during their initial stage of development, because structures, conditions and capabilities laid down in the past are unlikely to determine their spatial manifestation. Potential impacts of space are considered to be highly unpredictable: latent triggers or incentives providing opportunities and/or challenges are manifold, while the selection environment may operate only very weakly. As a consequence, we will claim that notions of human agency and accidents are necessitated to `explain' the spatial pattern of new industries. Because there is much uncertainty about the site where new industries will emerge, windows of locational opportunity tend to open up in the event of newly emerging industries: this theoretical concept holds the view that the long-term evolution of the spatial system is potentially, but not necessarily unstable.

description: Different authors have argued the importance of central banker's secrecy over alternative targets of monetary policy. One of the argument is based on the welfare results in a well known signalling game of monetary policy by Vickers (1986). This work aims to show how this argument crucially depends on the cost of separation and the specification of the prior beliefs held by private agents about the preferences of central banker. This is performed by solving a model similar to that solved by Vickers (1986) under a different assumption (a continuum of types) about the support of the distribution of prior beliefs. Welfare analysis shows that the result underlying the argument by Persson and Tabellini (1990) about the convenience of Central Banker's secrecy is upturned when the priors are skewed towards high inflation and alternative devices like credible pegging of a nominal variable, delegation and (negotiated) wage controls may be welfare enhancing. Furthermore, we show that if an appointed central banker has to incurr signalling costs a Rogoff (1985) type result can not be obtained and secrecy may be a bad substitute for commitment.

Nur anhand der Kernfläche, der Lokalisation, der Metastasierung und der Resektionsart konnten niedrigmaligne von hochmalignen MPNSTs (durch Vergleich von Überlebenszeiten bzw. Malignitätsgrad) unterschieden werden. Diese Ergebnisse legen die Vermutung nahe, daß das Malignitätsgrading maligner peripherer Nervenscheidentumoren durch die AgNOR-Analyse nicht ergänzt werden kann.
description: In a retrospective study 65 malignant peripheral nerve sheath tumors (MPNSTs) are distinguished from a control group of typical benign schwannomas (24 neurinomas) on the basis of a set of different evaluated parameters, i.e., number and absolute and relative areas of silver-staining nucleolar organizer regions (AgNOR), nuclear area, number and area of nucleoli, histologic grading (by using mitotic count and amount of necrosis), sex, age, differentiation, pattern of invasion, tendency to metastasize, kind of surgery for the primary tumors, location and staging. Only the nuclear area, the location, the tendency to metastasize and the kind of surgery discriminate between less aggressive MPNSTs (by comparing the histologic grading respectively the survival time) and more aggressive MPNSTs. These findings suggest that the assessment of histologic grading of MPNSTs could not be made effectively by the aid of AgNOR staining.

We also give a similar geometric description in the case of the linear orientation of a Dynkin quiver of type A.

description: A new theory is developed in this paper to explain the collapse of current gain in multi-finger power Al­GaAs/GaAs Heterojunction Bipolar Transistors. Two dif­ferent collapse patterns are investigated. The reasons be­hind this unwanted phenomenon are clarified using a sim­ple model to investigate the thermo-electrical interaction between the fingers. The method has been used to predict the collapse in AlGaAs/GaAs HBTs and the agreement is excellent.

description: In this paper it is proposed an automatic procedure to extract optimal layout parameters in order to thermal effect minimization, for a MESFET with conventional structure, according to other design specifications. These parameters are the gate length, the gate width, the number of gates, the gate to gate spacing, the die thickness and the heat sink temperature. The procedure accounts for the dependence of the thermal conductivity of gallium arsenide on temperature and doping density. Moreover the proposed procedure, joined with an I-V and a C-V MESFET thermal model already proposed by the authors is a part of a CAD tool for GaAs I.Cs. design for thermal effect optimization.

description: We investigate the low-energy (0.7-0.9eV) electroluminescence (EL) at low temperature (30 - 100 K) of short gate lattice-matched InP based HEMTs. This study allows to observe directly impact ionization in the "on" and "off" state Ino.53Gao.47As channel. In the on-state, the evolution of the luminescence as a function of the bias applied to the device shows that the electroluminescence intensity depends on two parameters: the gate-drain electric field and the drain current intensity. The voltage breakdown in the off-state is discussed in term of impact ionization in the InGaAs channel due to hot carriers originating from the gate leakage current.

description: The paper presents an efficient technique for evaluating the DC sensitivity of GaAs monopolar or bipolar devices through a two-carrier drift-diffusion model. The sensi­tivity analysis is based on the Branin's method for the sensitivity analysis of electrical networks. Numerical re­sults are presented concerning two topics: the behaviour of the distributed sensitivity within MESFET devices and the sensitivity-based statistical MESFET analysis with respect to random variations of the technological parameters, which is the basis of yield-driven device op­timization.

description: Let $S\subset \C^n$, $n\geq 3$ be a compact connected 2-codimensional submanifold having the following property: there exists a Levi-flat hypersurface whose boundary is $S$, possibly as a current. Our goal is to get examples of such $S$ containing at least one special 1-hyperbolic point: sphere with two horns; elementary models and their gluing. The particular cases of graphs are also described.

description: The in-plane dispersion relarions of the valence sub- bands of GaAs - Ga0.7Al0.3As quantum well are calcu- lated within the envelope function approximation. The anisotropy related with the difference between the Lut-tinger parameters ?2 and ?3 is taken into account con- sistently. The anisotropy proved to be considerable for  the ground valence subbands of heavy and light holes and the great values ok k. The cross sections of the  constant-energy surfaces of the valence subbans by the kxky  plane are built. The envelope wave functions of the  valence subbands as the mixture of the hole states dis-tinguished in mJ at k=0 are found. The change of the  percental contribution of the hole states different in mJ to the resultant state with k varying is investigated.

description: We give a critical overview of various attempts to describe gravity as an emergent phenomenon, starting from examples of condensed matter physics, to arrive to more sophisticated pregeometric models. The common line of thought is to view the graviton as a composite particle/collective mode. However, we will describe many different ways in which this idea is realized in practice.
Efficient infrared upconversion via a ladder-type atomic configuration

description: We have demonstrated experimentally that infrared light at 1529.4nm can be converted into the visible at 780nm with 54% efficiency through a ladder-type atomic configuration in 85Rb. Specifically we theoretically analyze that high efficiency is due to the large nonlinear dispersion of the index of refraction from the off-resonant enhancement in a four-wave mixing (FWM) process. By using two perpendicular polarized pump fields, the coherence of two FWM processes in this configuration is verified.

description: Ziel: Analyse und Vergleich CT-gesteuerter perkutaner Nadelbiopsien mit verschiedenen Punktionsnadeln. Methoden: Die Daten von 286 CT-gestützten Nadelbiopsien bei 274 Patienten wurden retrospektiv analysiert, insbesondere im Hinblick auf die Komplikationsrate und Verwertbarkeit des gewonnenen Materials der jeweils verwendeten Nadel. Es wurde eine 17-gauge, eine 20-gauge und zwei verschiedene 18-gauge Nadeln verwendet. Für die statistische Analyse kamen der Binominaltest und der Fisher exact Test zur Anwendung. Ergebnisse: Das Hauptaugenmerk der Betrachtung lag auf dem Vergleich der beiden 18-gauge Nadeln (Auto-Vac® and BioPince®), da nur hierbei genügend Daten für die Ermittlung statistisch signifikanter Unterschiede zur Verfügung standen. Das BioPince® System zeigte hierbei signifikant weiniger Komplikationen und eine bessere Gewebeausbeute als das Auto-Vac® System. Die perkutane CT-gestützte Biopsie ist eine relativ einfache und sichere diagnostische Methode, die eine genaue Diagnosestellung ermöglicht. Alle Komplikationen während oder unmittelbar nach der Punktion waren nicht schwerwiegend. Es war keine Intervention erforderlich.
description: Purpose: Analysis and comparison of CT-guided percoutaneous needle biopsies with various biopsy needles. Methods: The data of 286 CT-guided needle biopsies in 274 patients were evaluated retrospectively regarding the complication rate and usability of the extracted tissue of the chosen needle. A 17-gauge, a 20-gauge and two different 18-gauge needles were used. The Binominaltest and the Fisher exact test were employed for statistical analysis. Results: The main focus was the comparison of both the 18-gauge needles (Auto-VacB>® and BioPince®), because there was enough data to get statistically significant differences. With the BioPince® system we saw significantly less complications and more successful biopsies regarding the quality of the extracted tissue. CT-guided percoutaneous needle biopsy is an easy and safe procedure which can provide a precise diagnosis. All complications during or immediately after the biopsy were not severe. No intervention was necessary.
Towards an understanding of third-order galaxy-galaxy lensing

description: Third-order galaxy-galaxy lensing (G3L) is a next generation galaxy-galaxy lensing technique that either measures the excess shear about lens pairs or the excess shear-shear correlations about lenses. It is clear that these statistics assess the three-point correlations between galaxy positions and projected matter density. For future applications of these novel statistics, we aim at a more intuitive understanding of G3L to isolate the main features that possibly can be measured. We construct a toy model ("isolated lens model"; ILM) for the distribution of galaxies and associated matter to determine the measured quantities of the two G3L correlation functions and traditional galaxy-galaxy lensing (GGL) in a simplified context. The ILM presumes single lens galaxies to be embedded inside arbitrary matter haloes that, however, are statistically independent ("isolated") from any other halo or lens position. In the ILM, the average mass-to-galaxy number ratio of clusters of any size cannot change. GGL and galaxy clustering alone cannot distinguish an ILM from any more complex scenario. The lens-lens-shear correlator in combination with second-order statistics enables us to detect deviations from a ILM, though. This can be quantified by a difference signal defined in the paper. We demonstrate with the ILM that this correlator picks up the excess matter distribution about galaxy pairs inside clusters. The lens-shear-shear correlator is sensitive to variations among matter haloes. In principle, it could be devised to constrain the ellipticities of haloes, without the need for luminous tracers, or maybe even random halo substructure. [Abridged]

Possible origin of CMB temperature fluctuations: Vacuum fluctuations of Kaluza-Klein and string states during inflationary era

description: We point out that the temperature fluctuations of cosmic microwave background (CMB) can be generated in a way that is different from the one usually assumed in slow-roll inflation. Our mechanism is based on vacuum fluctuations of fields which are at rest at the bottom of the potential, such as Kaluza-Klein modes or string excited states. When there are a large number (typically of order $N\sim 10^{14}$) of fields with small mass in unit of Hubble parameter during the inflationary era, this effect can give significant contributions to the CMB temperature fluctuations. This number $N$ makes it possible to enhance scalar perturbation relative to tensor perturbation. Comparison with the observed amplitudes suggests that models with string scale of order $10^{-5}$ of 4D Planck scale are favorable.

description: We study diffusion processes in anomalous spacetimes regarded as models of quantum geometry. Several types of diffusion equation and their solutions are presented and the associated stochastic processes are identified. These results are partly based on the literature in probability and percolation theory but their physical interpretation here is different since they apply to quantum spacetime itself. The case of multiscale (in particular, multifractal) spacetimes is then considered through a number of examples and the most general spectral-dimension profile of multifractional spaces is constructed.

description: Since their first apparition, MMICs have been considered as very promising devices to allow miniaturization, increased reliability and cost reduction of space-borne equipment. All actors, i.e. agencies, foundries and payload manufacturers have joined their efforts to promote the introduction of MMICs in space programs. The aim of this paper is to illustrate this evolution taking examples from the achievements accomplished at Alcatel-Espace.
