description: Young people who cannot live with their birth families are provided with care through the child and youth welfare system. They are placed in foster, or residential care. In Germany, children and young people in care, and after leaving care are referred to with the English term “care leaver”. This phrase has become a code name for this group of persons in society. They have increasingly received attention from policy makers, and researchers over the last two decades. The chapter gives an overview to the German situation of children in and leaving care. It introduces the statistics in the field and the organizational, as well as legal framework, describes the path to independence when leaving care, and promising recent developments to empower care leavers, as well as to support self-organization.
description: Młodzież, która nie może mieszkać ze swoimi rodzinami urodzenia, jest objęta opieką w ramach systemu opieki nad dziećmi i młodzieżą. Są umieszczani w rodzinie zastępczej lub w domu opieki. W Niemczech dzieci i młodzież pozostające pod opieką oraz osoby opuszczające opiekę są nazywane angielskim terminem „wychowawca opieki”. To wyrażenie stało się kryptonimem dla tej grupy osób w społeczeństwie. Od dwudziestu lat przyciągają coraz większą uwagę decydentów i badaczy. Rozdział zawiera przegląd sytuacji dzieci pozostających pod opieką i opuszczających ją w Niemczech. Wprowadza statystyki w tej dziedzinie oraz ramy organizacyjne i prawne, opisuje drogę do niezależności po odejściu z opieki, a także obiecuje ostatnie osiągnięcia w zakresie wzmocnienia pozycji osób opuszczających opiekę zdrowotną, a także wspierania samoorganizacji.

description: lridictyon trebbaui Racenis, 1968 Figures 1-6 (larva) Material (19 ♂, 4 ♀:3larvae).- 15 ♂, 4 ♀, Unturan; 4 ♂, Tamacuari; 1 ♂, ultimate instar larva. 2 ♀, penultimate instar larvae, Unturan. Larva.- Occiput concave, occipital lobes with a dorsal tubercle; antennae as in Fig. 2, first segment twice the length of the head between anterior margin of clypeus and middle of occipital border. Labium as in Fig. 3. Hind border of pro notum broadly rounded, somewhat prominent in front of the mesostigmata; no spines or tubercles present. Wing sheaths reaching to end of abdominal segment 4. Lateral margin of abdominal segments 9 and 10 serrate, segment 10 with a blunt dorsomedian spine wich surpasses hind margin of this segment (Fig. 1). Male gonapophyses not reaching and of segment 9 (Fig. 4). Female gonapophyses (penultimate instar) shorter than segment 10; valves with several irregular rows of denticles. Caudal gills of the full-grown larva lost, those of the penultimate instar as shown in Figs. 5-6. Measurements (ultimate instar).- Total length (excl. caudal gills) 21.3; first antennal segment 1.8; hind femur 7.8; hind tibia 10.0; maximum width of posterior wing sheaths 1.8. Remarks.• The adult females do not show the usual dark and white wing bars, but have pale smoky wings. In one specimen a weak indication of a brown transverse stripe is discernible.- The larvae clung to submerged roots under the overhanging bank of the creek. So far undescribed, the larvae are associated with I. trebbaui by supposition. At both collecting sites this was the only Calopterygid present. The larva of Hetaerina medinai Racenis, a common pantepuyan species which -to my surprise- was not found in the region, differs in many ways from that of I. trebbaui (pers. observation). The broad wing sheaths and outer anal field in the latter provide further evidence for the correct identification. The small size of the full grown larva is noteworthy. The genus is endemic in the mountains of the Guayana shield ("pantepuyan", see Mayr & Phelps, 1967).

description: Most experimental realizations of quantum key distribution are based on the Bennett-Brassard 1984 (so-called BB84) protocol. In a typical optical implementation of this scheme, the sender uses an active source to produce the required BB84 signal states. While active state preparation of BB84 signals is a simple and elegant solution in principle, in practice passive state preparation might be desirable in some scenarios, for instance, in those experimental setups operating at high transmission rates. Passive schemes might also be more robust against side-channel attacks than active sources. Typical passive devices involve parametric down-conversion. In this paper, we show that both coherent light and practical single photon sources are also suitable for passive generation of BB84 signal states. Our method does not require any external-driven element, but only linear optical components and photodetectors. In the case of coherent light, the resulting key rate is similar to the one delivered by an active source. When the sender uses practical single photon sources, however, the distance covered by a passive transmitter might be longer than the one of an active configuration.

Larva.- Uniformly brown and hardly distinguishable in its general appearance from larvae of Chalcothore montgomeryi (Racenis) described by DeMarmels (1988). The caudal gills, presumably those structures of most diagnostic value, are, however, lost. Labium narrower than in Ch. montgomeryi; ovipositor surpassing end of segment 10 by one third of its length (less than one third in Ch. montgomeryi). Wing sheaths reaching end of segment 6 (end of segment 5 in Ch. montgomeryi). The latter two characters are usually subject to a high degree of variability. The figures of the larva of Chalcopteryx rutilans (Rambur) in SANTOS & COSTA (1987) are too generalized as to allow any comparison with Ch. scintillans. Measurements. Total length (excl. caudal gills) 8.6; hind femur 2.6; hind tibia 3.0.

description: We propose a mechanism for the vertical refinement of bigraphical reactive systems, based upon a mechanism for limiting observations and utilising the underlying categorical structure of bigraphs. We present a motivating example to demonstrate that the proposed notion of refinement is sensible with respect to the theory of bigraphical reactive systems; and we propose a sufficient condition for guaranteeing the existence of a safety-preserving vertical refinement. We postulate the existence of a complimentary notion of horizontal refinement for bigraphical agents, and finally we discuss the connection of this work to the general refinement of Reeves and Streader.

description: Bolometric corrections based on the optical-to-ultraviolet continuum spectrum of quasars are widely used to quantify their radiative output, although such estimates are affected by a myriad of uncertainties, such as the generally unknown line-of-sight angle to the central engine. In order to shed light on these issues, we investigate the state-of-the-art models of Hubeny et al. that describe the continuum spectrum of thin accretion discs and include relativistic effects. We explore the bolometric corrections as a function of mass accretion rates, black hole masses and viewing angles, restricted to the parameter space expected for type-1 quasars. We find that a nonlinear relationship log L_bol=A + B log(lambda L_lambda) with B<=0.9 is favoured by the models and becomes tighter as the wavelength decreases. We calculate from the model the bolometric corrections corresponding to the wavelengths lambda = 1450A, 3000A and 5100A. In particular, for lambda=3000A we find A=9.24 +- 0.77 and B=0.81 +- 0.02. We demonstrate that the often-made assumption that quasars emit isotropically may lead to severe systematic errors in the determination of L_bol, when using the method of integrating the "big blue bump" spectrum. For a typical viewing angle of ~30 degrees to the quasar central engine, we obtain that the value of L_bol resulting from the isotropy assumption has a systematic error of ~30% high compared to the value of L_bol which incorporates the anisotropic emission of the accretion disc. These results are of direct relevance to observational determinations of the bolometric luminosities of quasars, and may be used to improve such estimates.

Evaluation of the age-dependent role of natural killer t cells in gammaherpesvirus infection
Creators: name: Cho, Sehyun
Publisher: name: University of British Columbia
Year: 2016

description: Epstein-Barr virus (EBV), a human gammaherpesviruses, demonstrates age dependent- pathogenesis. EBV infection in young children is usually asymptomatic, whereas primary EBV infection later in life frequently results in the development of infectious mononucleosis (IM) due to uncontrolled expansion of CD8⁺ T lymphocytes. Natural killer (NK) T cells are innate T lymphocytes that respond to various pathogens through recognition of lipid antigens presented by CD1d receptors. Previous findings suggested that NKT cells have cytotoxic effects on EBV-infected cell lines. Furthermore, infection with other herpesviruses such as Kaposi’s sarcoma-associated herpesvirus (KSHV) and herpes simplex virus (HSV) can modulate the host immune response to evade NKT cells. To explain the age dependence of EBV pathogenesis, we hypothesized that there is an early window of opportunity to control gammaherpesvirus infection by invariant NKT cells. To test our hypothesis, we infected both neonatal and adult wild type and CD1d knock out (CD1d KO) C57BL/6 mice with murine gammaherpesvirus 68 (MHV-68). Our readout was the quantification of virus copy number by qPCR from genomic DNA extracted from lung and spleen. We report that there was no significant difference in symptoms and viral load between adult and young C57BL/6 and CD1dKO mice. We conclude that NKT cells do not have a major role in the control of gammaherpesvirus infection. The inability of NKT cells to control MHV-68 infection may be due to virus-mediated downregulation of CD1d expression on B cells.

description: We analyze the photometric short-cadence data obtained with the Kepler Mission during the first eight months of observations of two solar-type stars of spectral types G and F: KIC 11395018 and KIC 11234888 respectively, the latter having a lower signal-to-noise ratio compared to the former. We estimate global parameters of the acoustic (p) modes such as the average large and small frequency separations, the frequency of the maximum of the p-mode envelope and the average linewidth of the acoustic modes. We were able to identify and to measure 22 p-mode frequencies for the first star and 16 for the second one even though the signal-to-noise ratios of these stars are rather low. We also derive some information about the stellar rotation periods from the analyses of the low-frequency parts of the power spectral densities. A model-independent estimation of the mean density, mass and radius are obtained using the scaling laws. We emphasize the importance of continued observations for the stars with low signal-to-noise ratio for an improved characterization of the oscillation modes. Our results offer a preview of what will be possible for many stars with the long data sets obtained during the remainder of the mission.

title: Local Energy Markets - Simulative Evaluation and Field Test Application of Energy Markets on Distribution Grid Level
Creators: name: Schreck, Sebastian
Publisher: name: UNSPECIFIED
Year: 2023

description: Widespread introduction of Distributed Energy Resources (DERs) such as volatile renewable generation, electric vehicles, heat-pumps and battery storages causes a paradigm shift of the power system. Traditional power systems with few large-scale power plants are expanded or replaced by millions of small- to medium-size DERs. Local Energy Markets (LEMs) are a promising approach to facilitate the optimal operation and dispatch of DERs and enhance grid-integration on regional grid levels. In this Thesis, a novel linear-optimization-based market model for LEMs is developed. The market matching problem aims to maximize the social welfare of participants while considering technical and financial aspects of participants’ assets and the distribution grid. A simulative framework is set-up to evaluate the model with regards to its capabilities to foster the optimal use of flexibilities, to provide sufficient financial incentives for participants and to improve grid-integration. Yearly simulations of LEMs and a benchmark case are carried out for three different grid types (rural, semiurban, urban) and scenario years ranging from 2020 until 2035 in 5 year steps. The simulation results reveal that self-consumption and self-sufficiency of the local energy system can be increased by 4 ... 23 and 1 ... 9 percentage points depending on the grid type when compared to a business as usual benchmark case. An analysis of possible designs for regulated electricity price components in LEMs shows that a reduction of feed-in and load peaks of 30 ... 64 % can be achieved when considering power fees in the market matching problem. The simulative evaluation also shows that the market model is able to generate temporal, spatial, and asset-specific prices signals. Depending on the grid type and its load-generation ratio, participants with generation assets have higher benefits in urban, load-dominated grids whereas consumers have higher benefits in generation-dominated rural and semiurban grids. Load forecast uncertainty is identified as one of the major challenges in LEMs. Compared to simulations with perfect foresight, benefits of market participants are substantially decreased taking into account typical electric load forecast errors on the level of individual households. The application of the market model in a six months field-test in Southern Germany demonstrates the real world applicability of the developed approach. The field-test confirms findings from the simulative evaluation regarding the implication of forecast errors and generated price signals. It additionally shows that market interfaces to the Distribution System Operator (DSO) might further increase grid-integration capabilities of LEMs. By taking into account active power constraints of the DSO, 1499 events of critical grid load could be avoided.

The flow activation energy (ΔF) of various glasses when scaled with average molar volume Vm, which is defined as flow activation energy density ρ_E =ΔF/Vm, can be expressed as: D=(10G+K)/11 . The extended elastic model is suggestive for understanding the glass transition and deformation in metallic glasses.

description: We present an analysis of Spitzer-IRS spectroscopic maps of the L1157 protostellar outflow in the H2 pure-rotational lines from S(0) to S(7). The aim of this work is to derive the physical conditions pertaining to the warm molecular gas and study their variations within the flow. The mid-IR H2 emission follows the morphology of the precessing flow, with peaks correlated with individual CO clumps and H2 2.12μm ro-vibrational emission. More diffuse emission delineating the CO cavities is detected only in the low-laying transitions, with J(lower) less or equal to 2. The H2 line images have been used to construct 2D maps of N(H2), H2 ortho-to-para ratio and temperature spectral index beta, in the assumption of a gas temperature stratification where the H2 column density varies as T^(beta). Variations of these parameters are observed along the flow. In particular, the ortho-to-para ratio ranges from 0.6 to 2.8, highlighting the presence of regions subject to recent shocks where the ortho-to-para ratio has not had time yet to reach the equilibrium value. Near-IR spectroscopic data on ro-vibrational H2 emission have been combined with the mid-IR data and used to derive additional shock parameters in the brightest blue- and red-shifted emission knots. A high abundance of atomic hydrogen (H/H2 about 0.1-0.3) is implied by the observed H2 column densities, assuming n(H2) values as derived by independent SiO observations. The presence of a high fraction of atomic hydrogen, indicates that a partially-dissociative shock component should be considered for the H2 excitation in these localized regions. However, planar shock models, either of C- or J-type, are not able to consistently reproduce all the physical parameters derived from our analysis of the H2 emission. Globally, H2 emission contributes to about 50% of the total shock radiated energy in the L1157 outflow.

Investigation of capacity fade in flat-plate rechargeable alkaline MnO₂/Zn cells
Creators: name: Mehta, Sean
Publisher: name: University of British Columbia
Year: 2016

description: The rechargeable alkaline manganese dioxide-zinc (RAM™) battery system has been difficult to commercially develop in the past due to irreversible phase formation and progressive and cumulative capacity fade. This system has many advantages however, such as low cost and environmentally sustainable materials, long shelf life, moderate energy density, and safety. A flat-plate architecture was developed and investigated in half and full-cell apparatuses with the goal of understanding and improving cumulative capacity fade in the electrolytic manganese dioxide (EMD) cathode. Two types of cathode current collectors (CCs) were developed, a thin film foil CC and an expanded metal mesh CC and used to assess the effect of various additives over 30+ cycles under various operating conditions. Conductive carbon black (Super C65) and graphite (KS44) additives were shown to improve cell performance at 15 wt. % KS44 graphite providing an electrically conductive network between adjacent EMD particles. In addition, other chemical additives (BaSO₄, Sr(OH)₂•8H₂O, Ca(OH)₂, and Bi₂O₃) were investigated at 5 wt. % with Bi₂O₃ providing a reproducible improvement over a control recipe. Mechanical stability of the cathode electrode and pressure application were significant causes of cell failure. Slow rates of discharge, and shallow depth of discharge (DOD) charge/discharge protocols reduced capacity fade by limiting electrochemically irreversible phase formation such as Mn₂O₃, Mn₃O₄, Zn₂MnO₄, and Mn(OH)₂. Analytical characterization techniques including Scanning Electron Microscopy/ Energy Dispersive X-Ray Spectroscopy (SEM/EDS), X-Ray Photoelectron Spectroscopy (XPS), Powder X-Ray Diffraction (XRD), and Potentiostatic Electrochemical Impedance Spectroscopy (PEIS) were used to provide supporting evidence indicating that the main causes of capacity fade are linked to the cathode electrode’s mechanical properties, increased cell resistance, and progressive and irreversible phase formation.

description: Quillen et al. and O'Dea et al. carried out a Spitzer study of a sample of 62 brightest cluster galaxies (BCGs) from the ROSAT Brightest Cluster Sample chosen based on their elevated H-alpha flux. We present Hubble Space Telescope Advanced Camera for Surveys (ACS) far ultraviolet (FUV) images of the Ly-alpha and continuum emission of the luminous emission-line nebulae in 7 BCGs found to have an infrared excess. We confirm that the BCGs are actively forming stars suggesting that the IR excess seen in these BCGs is indeed associated with star formation. The FUV continuum emission extends over a region of ~7-28 kpc (largest linear size) and even larger in Ly-alpha. The young stellar population required by the FUV observations would produce a significant fraction of the ionizing photons required to power the emission line nebulae. Star formation rates estimated from the FUV continuum range from ~3 to ~14 times lower than those estimated from the IR, however both the Balmer decrement in the central few arcseconds and detection of CO in most of these galaxies imply that there are regions of high extinction that could have absorbed much of the FUV continuum. Analysis of archival VLA observations reveals compact radio sources in all 7 BCGs and kpc scale jets in Abell 1835 and RXJ 2129+00. The four galaxies with archival deep Chandra observations exhibit asymmetric X-ray emission, the peaks of which are offset from the center of the BCGs by ~10 kpc on average. A low feedback state for the AGN could allow increased condensation of the hot gas into the center of the galaxy and the feeding of star formation.

In this paper we draw these two strands of work together and discuss how we have implemented refinement checking in our Z2SAL toolset. The net effect of this work is that the SAL toolset can be used to check refinements between Z specifications supplied as input files written in the LaTeX mark-up. Two examples are used to illustrate the approach and compare it with a manual translation and refinement check.

description: We identify the complex plane C with the open unit disc D={z:|z|<1} by the homeomorphism z --> z/(1+|z|). This leads to a compactification $\bar{C}$ of C, homeomorphic to the closed unit disc. The Euclidean metric on the closed unit disc induces a metric d on $\bar{C}$. We identify all uniform limits of polynomials on $\bar{D}$ with respect to the metric d. The class of the above limits is an extension of the disc algebra and it is denoted by $\bar{A}(D)$. We study properties of the elements of $\bar{A}(D)$ and topological properties of the class $\bar{A}(D)$ endowed with its natural topology. The class $\bar{A}(D)$ is different and, from the geometric point of view, richer than the class $\tilde{A}(D)$ introduced in Nestoridis (2010), Arxiv:1009.5364, on the basis of the chordal metric.

description: As the global population is ageing, the demand for elderly care facilities and services is expected to increase. Assisted living technologies for detecting medical emergencies and assessing the wellness of the elderly are becoming more popular. A person normally performs activities of daily living (ADLs) on a regular basis. A person who is able to perform recurring ADLs indicates a certain wellness level. Anomalies in activity patterns of a person might indicate changes in the person's wellness. A method is proposed in this thesis for detecting anomalies in activity patterns of a lone occupant using electricity consumption measurements of his/her residence. The proposed method infers anomalies in activity patterns of an occupant from electricity consumption patterns without a need of explicitly monitoring the underlying individual activities. The proposed method provides a score which is a quantitative assessment of anomalies in the electricity consumption pattern of an occupant for a given day. A survey was conducted to obtain the hourly activities of three lone occupants for a month. The level of suspicion values, which are quantitative assessments of anomalies in the daily activity patterns of the occupants, were deduced from the survey. Using Fuzzy C-Means (FCM) clustering with Euclidean distance measure, the scores and level of suspicion values were clustered respectively. A day was then classified as regular or irregular based on the clustering results of the scores and level of suspicion values respectively. The results showed that anomalies in electricity consumption patterns can effectively reflect anomalies in the underlying activity patterns. The results also showed that the proposed feature and model based method outperforms a chosen raw data based approach. The performance of the proposed method was improved when subsets of features were considered based on the minimum Redundancy Maximum Relevance (mRMR) feature selection. A supervised learning method based on the Curious Extreme Learning Machine (C-ELM) was then proposed. The proposed method based on C-ELM (PM-CELM) outperforms the proposed method based on FCM (PM-FCM), but PM-FCM can operate without labelled training data.

description: The paper discusses the role of interpretations, understood as multifunctions that preserve and reflect logical consequence, as refinement witnesses in the general setting of pi-institutions. This leads to a smooth generalization of the refinement-by-interpretation approach, recently introduced by the authors in more specific contexts. As a second, yet related contribution a basis is provided to build up a refinement calculus of structured specifications in and across arbitrary pi-institutions.

This female corresponds well with a male from Patacame Island (Orinoco), in the MIZA collection. FRASER (1946) gives a brief description of the female, but no figure of the pro, thoracic hind lobe. Therefore the identification of the Mavaca female remains somewath doubtful.

description: Comparing models and data of pulsating stars is a powerful way to understand the stellar structure better.βHyi is an evolved solar-type pulsator with mixed modes in its frequency spectrum, making it very interesting for asteroseismic studies.The goal of this work is to search for the best model of the solar-type star βHyi, based on up-to-date non-seismic and seismic data.We present a revised list of frequencies for 33 modes, which we produced by analysing the power spectrum of the published observations again using a new weighting scheme that minimises the daily sidelobes.We ran several grids of evolutionary models with different input parameters and different physics, using the stellar evolutionary code ASTEC.For the models that are inside the observed error box of βHyi, we computed their frequencies with the pulsation code ADIPLS.We used two approaches to find the model that oscillates with the frequencies that are closest to the observed frequencies of βHyi:(i)we assume that the best model is the one that reproduces the star's interior based on the radial oscillation frequencies alone, to which we have applied the correction for the near-surface effects;(ii)we assume that the best model is the one that produces the lowest value of the chi-square (\chi2), i.e. that minimises the difference between the observed frequencies of all available modes and the model predictions, after all model frequencies are corrected for near-surface effects.We show that after applying this correction to the frequencies of the best models, we can reproduce the observed modes well, including the mixed modes.The model that gives the lowest value of the \chi2 is a post-main-sequence model with a mass of 1.04 MSun and a metallicity slightly lower than that of the Sun.Our results underscore the importance of having individual frequencies to constrain the properties of the stellar model.

description: Simulink/Stateflow charts are widely used in industry for the specification of control systems, which are often safety-critical. This suggests a need for a formal treatment of such models. In previous work, we have proposed a technique for automatic generation of formal models of Stateflow blocks to support refinement-based reasoning. In this article, we present a refinement strategy that supports the verification of automatically generated sequential C implementations of Stateflow charts. In particular, we discuss how this strategy can be specialised to take advantage of architectural features in order to allow a higher level of automation.

Dynamic analysis of arch dams : effect of thermal loading
Creators: name: Moghadas Jafari, Ryhane
Publisher: name: University of British Columbia

description: Conducting a case study, this thesis investigates the dynamic behavior of Karun IV arch dam (Iran) under the effect of maximum feasible thermal input. A three-dimensional finite element model is created using ANSYS software. The thesis determines the impact of thermal loadings under two scenarios of normal and minimum water levels. The dam-foundation, dam-water and water-foundation interactions are considered in the modeling to accurately capture its dynamic response. Furthermore, in addition to the water compressibility, appropriate wave absorbing boundaries are used for the reservoir far end and bottom and for the foundation. Stability, static, modal, and thermal analyses are conducted as initial conditions. Using three orthogonal earthquake components, linear dynamic time history analyses with and without thermal loading are performed. The comparison of the results verified that the application of thermal effects on the dynamic analysis increases the maximum tension, changes the maximum pressure, and decreases the displacements in the dam body. This study concludes that thermal loading must be considered in the dynamic analysis of an arch dam as it can worsen the tensile cracks.
On the existence of non-abelian monopoles: the algebro-geometric approach

description: We develop the Atiyah-Drinfeld-Manin-Hitchin-Nahm construction to study SU(2) non-abelian charge 3 monopoles within the algebro-geometric method. The method starts with finding an algebraic curve, the monopole spectral curve, subject to Hitchin's constraints. We take as the monopole curve the genus four curve that admits a $C_3$ symmetry, $η^3+αηζ^2+βζ^6+γζ^3-β=0$, with real parameters $α$, $β$ and $γ$. In the case $α=0$ we prove that the only suitable values of $γ/β$ are $\pm 5\sqrt{2}$ ($β$ is given below) which corresponds to the tetrahedrally symmetric solution. We then extend this result by continuity to non-zero values of the parameter $α$ and find finally a {\em new} one-parameter family of monopole curves with $C_3$ symmetry.

description: We report the results concerning the influence of vacuum polarization due to quantum massive vector, scalar and spinor fields on the scalar sector of quasinormal modes in spherically symmetric charged black holes. The vacuum polarization from quantized fields produces a shift in the values of the quasinormal frequencies, and correspondingly the semiclassical system becomes a better oscillator with respect to the classical Reissner-Nordström black hole.

From constructive field theory to fractional stochastic calculus. (I) An introduction: rough path theory and perturbative heuristics
Creators: name: Magnen, Jacques

Publisher: name: arXiv

Subjects: subject: Probability (math.PR)

description: Let $B=(B_1(t),..,B_d(t))$ be a $d$-dimensional fractional Brownian motion with Hurst index $α\le 1/4$, or more generally a Gaussian process whose paths have the same local regularity. Defining properly iterated integrals of $B$ is a difficult task because of the low Hölder regularity index of its paths. Yet rough path theory shows it is the key to the construction of a stochastic calculus with respect to $B$, or to solving differential equations driven by $B$. We intend to show in a forthcoming series of papers how to desingularize iterated integrals by a weak singular non-Gaussian perturbation of the Gaussian measure defined by a limit in law procedure. Convergence is proved by using "standard" tools of constructive field theory, in particular cluster expansions and renormalization. These powerful tools allow optimal estimates of the moments and call for an extension of the Gaussian tools such as for instance the Malliavin calculus. This first paper aims to be both a presentation of the basics of rough path theory to physicists, and of perturbative field theory to probabilists; it is only heuristic, in particular because the desingularization of iterated integrals is really a {\em non-perturbative} effect. It is also meant to be a general motivating introduction to the subject, with some insights into quantum field theory and stochastic calculus. The interested reader should read in a second time the companion article \cite{MagUnt2} (or a preliminary version arXiv:1006.1255) for the constructive proofs.
