description: A multiobjective optimization model integrating with high-resolution geographical data was applied to examine the optimal switchgrass supply system in Tennessee that considers both feedstock cost and greenhouse gas (GHG) emissions in the system. Results suggest that the type of land converted into switchgrass production is crucial to both plant gate cost and GHG emissions of feedstock. In addition, a tradeoff relationship between cost and GHG emissions for the switchgrass supply is primarily driven by the type of land converted. The imputed cost of lowering GHG emissions in the feedstock supply system was also calculated based on the derived tradeoff curve.

description: Alltagsbeanspruchungen von Primarlehrpersonen, die sich im Zusammenhang mit dem kindlichen Körpersein und Bewegungsverhalten in der Primarschule ergeben, werden als Ausgangspunkt ge-nommen, um damit verbundene bewältigungsrelevante sportpädagogische Handlungs- und Interakti-onsstrategien zu erfassen und theoriebildend aufzuarbeiten. In einem empirisch-qualitativen Vorgehen wurden nach dem methodischen Verfahren der Grounded Theory zehn Expertengespräche mit Primarlehrpersonen geführt. Zwei Forschungsfragen stehen im Interessensmittelpunkt. Die erste Frage geht Themen, Situationen und Erlebnissen aus dem bewe-gungs-, körper- und sportbezogenen schulischen Handlungsfeld nach, die für Primarlehrpersonen im Schulalltag subjektiv relevant und beanspruchend sind. Die Folgefrage sucht nach sportpädagogi-schen Handlungs- und Interaktionsstrategien, die für Primarlehrpersonen bei der Gestaltung und Be-wältigung von Alltagsbeanspruchungen handlungsleitend sind. Die Themen ‚Sicherheit in bewegungs-, sport- und körperbezogenen schulischen Alltagssituationen‘, ‚leistungs-, wettkampf- und fairnessthematisch vernetzte Situationen‘, ‚Bewegungsverhalten und Körper-sein der Primarschulkinder im Schulzimmer‘, ‚Komplexität des Sportunterrichts‘ und als übergeordne-tes Thema ‚Individualität und Selbstbestimmungsstreben der Primarschulkinder im Körpersein, Bewe-gungs- und Sportverhalten‘, werden als Ergebnisse ausführlich und systemtisch beschrieben. Das Bewältigungshandeln der Primarlehrpersonen - und damit die Beantwortung der zweiten Forschungs-frage - kommt in der Darstellung von über fünfzig Handlungs- und Interaktionsstrategien mit je spezifischen Wirkrichtungen zum Ausdruck. Im Verweisungszusammenhang zu ausgewählten theoretischen Modellen und empirischen Befunden, stellen die fünf Themenkreise eine vielschichtige Interpretationsgrundlage dar, sowohl als Referenz-punkt für die Beanspruchungserfahrungen, als insbesondere auch für den Entwurf einer Theorie mittlerer Reichweite, welche die beiden Aspekte Akteurorientierung und Reflexion als Bezugspunkte für erfolgreiches sportpädagogisches Handeln im Primarschulalltag entschlüsselt.

description: We consider real eigen-functions of the Schrödinger operator in 2-d. The nodal lines of separable systems form a regular grid, and the number of nodal crossings equals the number of nodal domains. In contrast, for wave functions of non integrable systems nodal intersections are rare, and for random waves, the expected number of intersections in any finite area vanishes. However, nodal lines display characteristic avoided crossings which we study in the present work. We define a measure for the avoidance range and compute its distribution for the random waves ensemble. We show that the avoidance range distribution of wave functions of chaotic systems follow the expected random wave distributions, whereas for wave functions of classically integrable but quantum non-separable wave functions, the distribution is quite different. Thus, the study of the avoidance distribution provides more support to the conjecture that nodal structures of chaotic systems are reproduced by the predictions of the random waves ensemble.

description: Large scale cloud services use Key Performance Indicators (KPIs) for tracking and monitoring performance. They usually have Service Level Objectives (SLOs) baked into the customer agreements which are tied to these KPIs. Dependency failures, code bugs, infrastructure failures, and other problems can cause performance regressions. It is critical to minimize the time and manual effort in diagnosing and triaging such issues to reduce customer impact. Large volume of logs and mixed type of attributes (categorical, continuous) in the logs makes diagnosis of regressions non-trivial. In this paper, we present the design, implementation and experience from building and deploying DeCaf, a system for automated diagnosis and triaging of KPI issues using service logs. It uses machine learning along with pattern mining to help service owners automatically root cause and triage performance issues. We present the learnings and results from case studies on two large scale cloud services in Microsoft where DeCaf successfully diagnosed 10 known and 31 unknown issues. DeCaf also automatically triages the identified issues by leveraging historical data. Our key insights are that for any such diagnosis tool to be effective in practice, it should a) scale to large volumes of service logs and attributes, b) support different types of KPIs and ranking functions, c) be integrated into the DevOps processes.

description: We use large-scale numerical simulations to study the formation and evolution of non-topological defects in a generalized electroweak phase transition described by the Glashow-Salam-Weinberg model without fermions. Such defects include dumbbells, comprising a pair of monopoles joined by a segment of electroweak string. These exhibit complex dynamics, with some shrinking under the string tension and others growing due to the monopole-antimonopole attractions between near neighbours. We estimate the range of parameters where the network of dumbbells persists, and show that this region is narrower than the region within which infinite straight electroweak strings are perturbatively stable.

description: In magnetic fields applied parallel to the anisotropy axis, the magnetization of Mn$_{12}$ has been measured in response to a field that is swept back and forth across the resonances corresponding to steps $N=4,5,...9$. The fraction of molecules remaining in the metastable well after each sweep through the resonance is inconsistent with expectations for an ensemble of identical molecules. The data are consistent instead with the presence of a broad distribution of tunnel splittings. A very good fit is obtained for a Gaussian distribution of the second-order anisotropy tunneling parameter $X_E=-\ln(\mid E\mid/2D)$. We show that dipolar shuffling is a negligible effect which cannot explain our data.

Simple views on symmetries and dualities in the theory of elasticity

Year: 2019
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Microscopic symmetries impose strong constraints on the elasticity of a crystalline solid. In addition to the usual spatial symmetries captured by the tensorial character of the elastic tensor, hidden non-spatial symmetries can occur microscopically in special classes of mechanical structures. Examples of such non-spatial symmetries occur in families of mechanical metamaterials where a duality transformation relates pairs of different configurations. We show on general grounds how the existence of non-spatial symmetries further constrains the elastic tensor, reducing the number of independent moduli. In systems exhibiting a duality transformation, the resulting constraints on the number of moduli are particularly stringent at the self-dual point but persist even away from it, in a way reminiscent of critical phenomena.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Computational Tools for Stereo and Light Field Photography

Subjects: 000 Computer science, knowledge & systems

description: This thesis covers a broad part of the field of computational photography, including video stabilization and image warping techniques, introductions to light field photography and the conversion of monocular images and videos into stereoscopic 3D content. We present a user assisted technique for stereoscopic 3D conversion from 2D images. Our approach exploits the geometric structure of perspective images including vanishing points. We allow a user to indicate lines, planes, and vanishing points in the input image, and directly employ these as guides of an image warp that produces a stereo image pair. Our method is most suitable for scenes with large scale structures such as buildings and is able to skip the step of constructing a depth map. Further, we propose a method to acquire 3D light fields using a hand-held camera, and describe several computational photography applications facilitated by our approach. As the input we take an image sequence from a camera translating along an approximately linear path with limited camera rotations. Users can acquire such data easily in a few seconds by moving a hand-held camera. We convert the input into a regularly sampled 3D light field by resampling and aligning them in the spatio-temporal domain. We also present a novel technique for high-quality disparity estimation from light fields. Finally, we show applications including digital refocusing and synthetic aperture blur, foreground removal, selective colorization, and others.
Parameters' domain in three flavour neutrino oscillations

description: We consider analytically the domain of the three mixing angles $Θ_{ij}$ and the CP phase $δ$ for three flavour neutrino oscillations both in vacuum and matter. Similarly to the quark sector, it is necessary and sufficient to let all the mixing angles $Θ_{12},Θ_{13},Θ_{23}$ and $δ$ be in the range $<0,\fracπ{2}>$ and $0 \leq δ< 2 π$, respectively. To exploit the full range of $δ$ will be important in future when more precise fits are possible, even without CP violation measurements. With the above assumption on the angles we can restrict ourselves to the natural order of masses $m_1

Image Space Adaptive Rendering
Creators: name: Rousselle, Fabrice
Publisher: name: Universität Bern
Year: 2014
Subjects: 000 Computer science, knowledge & systems

description: In this thesis, we develop an adaptive framework for Monte Carlo rendering, and more specifically for Monte Carlo Path Tracing (MCPT) and its derivatives. MCPT is attractive because it can handle a wide variety of light transport effects, such as depth of field, motion blur, indirect illumination, participating media, and others, in an elegant and unified framework. However, MCPT is a sampling-based approach, and is only guaranteed to converge in the limit, as the sampling rate grows to infinity. At finite sampling rates, MCPT renderings are often plagued by noise artifacts that can be visually distracting. The adaptive framework developed in this thesis leverages two core strategies to address noise artifacts in renderings: adaptive sampling and adaptive reconstruction. Adaptive sampling consists in increasing the sampling rate on a per pixel basis, to ensure that each pixel value is below a predefined error threshold. Adaptive reconstruction leverages the available samples on a per pixel basis, in an attempt to have an optimal trade-off between minimizing the residual noise artifacts and preserving the edges in the image. In our framework, we greedily minimize the relative Mean Squared Error (rMSE) of the rendering by iterating over sampling and reconstruction steps. Given an initial set of samples, the reconstruction step aims at producing the rendering with the lowest rMSE on a per pixel basis, and the next sampling step then further reduces the rMSE by distributing additional samples according to the magnitude of the residual rMSE of the reconstruction. This iterative approach tightly couples the adaptive sampling and adaptive reconstruction strategies, by ensuring that we only sample densely regions of the image where adaptive reconstruction cannot properly resolve the noise. In a first implementation of our framework, we demonstrate the usefulness of our greedy error minimization using a simple reconstruction scheme leveraging a filterbank of isotropic Gaussian filters. In a second implementation, we integrate a powerful edge aware filter that can adapt to the anisotropy of the image. Finally, in a third implementation, we leverage auxiliary feature buffers that encode scene information (such as surface normals, position, or texture), to improve the robustness of the reconstruction in the presence of strong noise.

description: The strong spatial confinement of a nanocavity plasmonic field has made it possible to visualize the inner structure of a single molecule and even to distinguish its vibrational modes in real space. With such ever-improved spatial resolution, it is anticipated that full vibrational imaging of a molecule could be achieved to reveal molecular structural details. Here we demonstrate full Raman images of individual vibrational modes on the Ångström level for a single Mg-porphine molecule, revealing distinct characteristics of each vibrational mode in real space. Furthermore, by exploiting the underlying interference effect and Raman fingerprint database, we propose a new methodology for structural determination, coined as scanning Raman picoscopy, to show how such ultrahigh-resolution spectromicroscopic vibrational images can be used to visually assemble the chemical structure of a single molecule through a simple Lego-like building process.

description: In this paper, we build from previous work (Bustard et al. 2018) and present simulations of recent (within the past Gyr), magnetized, cosmic ray driven outflows from the Large Magellanic Cloud (LMC), including our first attempts to explicitly use the derived star formation history of the LMC to seed outflow generation. We run a parameter set of simulations for different LMC gas masses and cosmic ray transport treatments, and we make preliminary comparisons to published outflow flux estimates, neutral and ionized hydrogen observations, and Faraday rotation measure maps. We additionally report on the gas mass that becomes unbound from the LMC disk and swept by ram pressure into the Trailing Magellanic Stream. We find that, even for our largest outburst, the mass contribution to the Stream is still quite small, as much of the outflow-turned-halo gas is shielded on the LMC's far-side due to the LMC's primarily face-on infall through the Milky Way halo over the past Gyr. On the LMC's near-side, past outflows have fought an uphill battle against ram pressure, with near-side halo mass being at least a factor of a few smaller than the far-side. Absorption line studies probing only the LMC foreground, then, may be severely underestimating the total mass of the LMC halo formed by outflows.

In particular, violation of classical realism in terms of the GHZ and GHSH conditions is proved. We discuss a new property of entanglement expressed in terms of local measurements. We also show that generation of entangled states in the atom-photon systems under consideration strongly depends on the choice of initial conditions and that the parasitic influence of cavity detuning can be compensated through the use of Kerr medium.

description: The statistics of the nodal lines and nodal domains of the eigenfunctions of quantum billiards have recently been observed to be fingerprints of the chaoticity of the underlying classical motion by Blum et al. (Phys. Rev. Lett., Vol. 88 (2002), 114101) and by Bogomolny and Schmit (Phys. Rev. Lett., Vol. 88 (2002), 114102). These statistics were shown to be computable from the random wave model of the eigenfunctions. We here study the analogous problem for chaotic maps whose phase space is the two-torus. We show that the distributions of the numbers of nodal points and nodal domains of the eigenvectors of the corresponding quantum maps can be computed straightforwardly and exactly using random matrix theory. We compare the predictions with the results of numerical computations involving quantum perturbed cat maps.

description: We report high-resolution resonant inelastic x-ray scattering (RIXS) measurements of the collective spin fluctuations in three compositions of the superconducting cuprate system La2-xSrxCuO4. We have mapped out the excitations throughout much of the 2-D (h,k) Brillouin zone. The spin fluctuations in La2-xSrxCuO4 are found to be fairly well-described by a damped harmonic oscillator model, thus our data allows us to determine the full wavevector dependence of the damping parameter. This parameter increases with doping and is largest along the (h, h) line, where it is peaked near (0.2,0.2). We have used a new procedure to determine the absolute wavevector-dependent susceptibility for the doped compositions La2-xSrxCuO4 (x=0.12,0.16) by normalising our data to La2CuO4 measurements made with inelastic neutron scattering (INS). We find that the evolution with doping of the intensity of high-energy excitations measured by RIXS and INS is consistent. For the doped compositions, the wavevector-dependent susceptibility is much larger at (1/4,1/4) than at (1/2,0). It increases rapidly along the (h,h) line towards the antiferromagnetic wavevector of the parent compound (1/2,1/2). Thus, the strongest magnetic excitations, and those predicted to favour superconductive pairing, occur towards the (1/2,1/2) position as observed by INS.

description: We study theoretically the bulk modulus (inverse of the compressibility) of a suspension of charged objects (macro-ions), making use of a cell model to account for the finite density of macro-ions. The diffuse layer of charged micro-species around a macro-ion is described by a generic local density functional theory. Within this general framework, we obtain the condition for a positive bulk modulus, which is fulfilled by several proposals made in the literature and rules out the possibility of a critical point. We show that a sufficient condition for a positive compressibility also ensures that the same theory produces repulsive effective pair potentials.

Zur Messbarkeit sozialer Beziehungen in Schulklassen
Creators: name: Anliker, Brigitte

Subjects: 300 Social sciences, sociology & anthropology

description: Das soziale Eingebettetsein in die Schulklasse hat einen grossen Einfluss auf die Entwicklung von Kindern und Jugendlichen. Aber auch die Klasse als Lerngruppe wird in ihrer Entwicklung, Handlungsmöglichkeit und Funktionsfähigkeit stark von den sozialen Positionen der einzelnen Schülerinnen und Schülern beeinflusst. Damit ungünstige soziale Stellungen von Schülerinnen und Schülern erkannt werden und gezielte Interventionen – die problematischen Prozessen entgegen wirken – möglich werden, ist zum einen eine eingehende Beschäftigung mit sozialen Prozessen unabdingbar, und zum anderen kommt einer adäquaten Erfassung sozialer Beziehungen in Schulklassen grosse Bedeutung zu. Nach wie vor stellen soziometrische Verfahren für Schulklassen praxiskompatible Instrumente dar. So ist die Erhebung und Auswertung soziometrischer Daten relativ einfach, die Erhebung dauert nur wenige Minuten und die Auswertung, sofern sie computergestützt möglich ist, geht ebenfalls schnell. Ausgehend davon ist das Ziel dieser Inauguraldissertation das soziometrische Verfahren SOZIO vor dem Hintergrund der klassischen Testtheorie auf die Güte der Qualitätskriterien Reliabilität und Validität hin zu überprüfen. Die Validierungsstudie umfasst einerseits die Überprüfung von Hypothesen zu Übereinstimmung bzw. Abgrenzung mit anderen Testverfahren, die jeweils dasselbe bzw. ein abweichendes Konstrukt zu erfassen suchen. Andererseits werden Hypothesen überprüft, die auf theoretischen Argumenten und empirischen Befunden zu Zusammenhängen zwischen den Konstrukten von SOZIO und der Schulleistung, angemessenem Sozialverhalten sowie verschiedenen Funktionen der Aggression gründen. 60 Klassen der Mittel- und Oberstufe wurden während eines halben Jahres dreimal befragt. Die Ergebnisse zeigen: Mit dem soziometrischen Verfahren SOZIO lassen sich valide Aussagen zu Aspekten sozialer Beziehungen in Gruppen machen. Bevor das Verfahren einer breiten Öffentlichkeit zur Verfügung gestellt werden kann, sind jedoch gewisse Überarbeitungen angezeigt. Diese betreffen im Wesentlichen die Bezeichnungen und Beschreibungen gewisser Masse. Zudem sollte Berechnungsgrundlage eines zentralen Masses überdacht werden und zwei Masse sollten, aufgrund mangelnder Reliabilität, ausgeschlossen werden.

description: The effect of Non-centrosymmetricity on electronic and optical properties has been investigated using grid based projector augmented wave method code GPAW. The calculation of band gap using GLLB-SC which improves on the exchange potential and explicitly estimates the derivative discontinuity is similar to experimental result. Ferro-electricity of BaHfO$_{3}$ is increased as lattice distortion kept on increasing. Static dielectric constant, index of refraction only show slight change and in good agreement with experimental and other results. Absorption reaches highest peaks in visible frequency range, and absorption coefficient decreased as light goes through BaHfO$_{3}$ bulk, this in turn enhance excitonic property. Exciton binding energy increased over lattice distortion sites. The presented results are important in connection with development of typical perovskite optoelectronic device properties.

description: A supersymmetric standard model with two Higgs doublets and two Higgs singlets is investigated if it can accommodate the possibility of spontaneous CP violation. Assuming the degeneracy of the scalar quark masses of the third generation, we find that spontaneous CP violation in the Higgs sector is viable in our model. In the case of spontaneous CP violation, the masses of the lightest two neutral Higgs bosons are estimated to be 80 and 125 GeV for some parameter values in our model, which, are consistent with LEP2 data.

description: Motivated by experimental limitations commonly met in the design of solid state quantum computers, we study the problems of non-local Hamiltonian simulation and non-local gate synthesis when only homogeneous local unitaries are performed in order to tailor the available interaction. Homogeneous (i.e. identical for all subsystems) local manipulation implies a more refined classification of interaction Hamiltonians than the inhomogeneous case, as well as the loss of universality in Hamiltonian simulation. For the case of symmetric two-qubit interactions, we provide time-optimal protocols for both Hamiltonian simulation and gate synthesis.

Space debris cataloging of GEO objects by using Meta-Heuristic methods

Publisher: name: Universität Bern
Year: 2017
Subjects: 520 Astronomy

description: Currently several thousands of objects are being tracked in the Medium Earth Orbit (MEO) and Geosynchronous Earth Orbit (GEO) regions through optical means. The problem faced in this framework is that of Multiple Target Tracking (MTT). The MTT problem becomes an NP-hard combinatorial optimization problem as soon as its dimension S becomes S ≥ 3. In regions with a high density of objects the MTT problem will have to have this dimension in order to avoid ambiguous solutions. With the advent of improved sensors and a eightened interest in the problem of space debris, it is expected that the number of tracked objects will grow by an order of magnitude in the near future. This research aims to identify an algorithm capable of addressing the problem of space debris cataloging in the MEO and GEO regions, in particular for highly dense regions, without possessing a restrictive computational complexity. In an attempt to find an approximate solution of sufficient quality several Population Based Meta Heuristic (PBMH) algorithms are implemented and tested on simulated optical measurements. In addition to this, a novel way of orbit determination is presented which is based on an existing S = 2 tracklet association method. These first results show promise as one of the tested algorithms (the Elitist Genetic Algorithm (EGA)) consistently displays the desired behavior of finding good approximate solutions before reaching the optimum. Furthermore, the results suggest that the algorithm has a polynomial time complexity when finding approximate solutions. The algorithm is also applied to real observations, where it also performs as desired.

description: In the midst of a climate crisis and growing social inequity, our economic mindset must adapt to our current reality. While some form of introductory economics is taken by 40% of undergraduate students across the US, these courses are not centered around the environmental and social contexts that researchers have shown affect our economy. This work is an entry into the discussion on mainstream economics and its effects on slowing down progress on climate change.
Interaction of a soliton with a localized gain in a fiber Bragg grating

description: A model of a lossy nonlinear fiber grating with a "hot spot", which combines a local gain and an attractive perturbation of the refractive index, is introduced. A family of exact solutions for pinned solitons is found in the absence of loss and gain. In the presence of the loss and localized gain, an instability threshold of the zero solution is found. If the loss and gain are small, it is predicted what soliton is selected by the energy-balance condition. Direct simulations demonstrate that only one pinned soliton is stable in the conservative model: solitons with a larger energy relax to it via emission of radiation, while those with a smaller energy decay. In the model with the loss and gain, stable pinned pulses demonstrate persistent internal vibrations and emission of radiation. If these solitons are nearly stationary, the prediction based on the energy balance underestimates the necessary gain by 10% to 15% (due to radiation loss). If the loss and gain are larger, the intrinsic vibrations of the pinned soliton become chaotic. The local gain alone, without the attractive perturbation of the local refractive index, cannot maintain a stable pinned soliton. For collisions of moving solitons with the "hot spot", passage and capture regimes are identified, the capture actually implying splitting of the soliton.

Advanced Techniques in Gradient-Domain Rendering
Creators: name: Manzi, Marco
Publisher: name: Universität Bern

description: Rendering realistic images requires solving the notoriously hard physically-based light transport problem. Almost all of the state-of-the-art physically-based rendering methods use Monte-Carlo sampling of the light paths contributing to the image. These methods suffer from variance until convergence. Depending on the scene, an impracticable amount of time might be required to get a clean image. A recently developed method called gradient-domain Metropolis light transport mitigates this problem. It first samples the image-space finite differences of paths alongside the paths themselves and then reconstructs a clean image from the sampled data by applying a screened Poisson reconstruction. The method exploits two properties: first, the gradients of natural images are usually much sparser than the image itself, thus sampling efforts can be concentrated in fewer regions of the path space. Second, sampling finite differences allows using correlated sampling in rendering, which can strongly reduce noise in the finite differences. Both properties combined lead to dramatical speed-ups compared to classical (Markov-chain) Monte-Carlo rendering methods. This dissertation builds up on the aforementioned gradient-domain Metropolis light transport and proposes a number of improvements and generalizations. We improve the sampling by replacing finite differences by arbitrary differences and by combining different sampling strategies in an unbiased way. We also generalize the method to non-MLT rendering methods like bidirectional path tracing. Further, we develop an algorithm that regularizes the screened Poisson reconstruction by using auxiliary scene information in order to increase image quality. This leads to the first method that combines gradient-domain rendering with classical image-space denoising. And finally, we incorporate temporal finite differences in gradient-domain rendering in order to create stable animations, thus making gradient-domain rendering an even more appealing option for production rendering.

description: We study in detail the main features of the unitarized Regge model (CFKS), recently proposed to describe the small-$Q^2$ domain. It takes into account a two-component description with two types of unitarized contributions: one is the multiple pomeron exchange contribution, interacting with the large dipole configurations, and the other one consists of a unitarized dipole cross section, describing the interaction with the small size dipoles. We analyze the ratio between soft and hard pieces as a function of the virtuality, and also compare the resulting dipole cross section to that from the saturation model. Diffraction dissociation is also considered, showing the scaling violations in diffractive DIS and estimating the corresponding logarithmic slope.
