description: This paper addresses the symbolic representation of non-convex real polyhedra, i.e., sets of real vectors satisfying arbitrary Boolean combinations of linear constraints. We develop an original data structure for representing such sets, based on an implicit and concise encoding of a known structure, the Real Vector Automaton. The resulting formalism provides a canonical representation of polyhedra, is closed under Boolean operators, and admits an efficient decision procedure for testing the membership of a vector.

description: Coupled fermionic chains are usually described by an effective model written in terms of bonding and anti-bonding spinless fields with linear dispersion in the vicinities of the respective Fermi points. We derive for the first time exact Ward Identities (WI) for this model, proving the existence of chiral anomalies which verify the Adler-Bardeen non-renormalization property. Such WI are expected to play a crucial role in the understanding of the thermodynamic properties of the system. Our results are non-perturbative and are obtained analyzing Grassmann functional integrals by means of Constructive Quantum Field Theory methods.

Local probe of electronic states in high mobility quantum Hall samples

Publisher: name: University of British Columbia

description: The discovery of the integer quantum Hall effect (IQHE) and the fractional quantum Hall effect (FQHE) in a 2-dimensional electron gas (2 DEG ) have created a new and rich field in condensed matter physics in low dimensions. Almost 35 years after these discoveries, there are still several unanswered questions regarding the nature of various electronic phases formed in such systems. The 2 DEG in ultra-high mobility quantum well (QW) samples in large magnetic fields and millikelvin temperatures are studied in this thesis. We developed a reproducible recipe for enhancing the quality of the very fragile FQHE states reliably, which can be used to reset an electrically shocked sample in-situ at low temperatures. We then developed a protocol for measuring the local electronic density on QW samples using a single-electron transistor (SET). We also developed a technique for modulating the temperature of the sample at about 10Hz by about 10mK. We used the electrometer and the fast temperature modulator to obtain a measure of changes in chemical potential as a function of temperature oscillations. This quantity can reveal the existence of an enhanced entropy in the state of the electrons. We investigated theories that predict the non-Abelian state of matter, that follows neither Fermionic nor Bosonic statistics. Non-Abelian quasi-particles are expected to form as collective excitations in the fractional quantum Hall regime at filling factor ν=5/2. The experimental results were incompatible with the non-Abelian theory under investigation. We also studied the nature of localization of electrons in the bulk of the sample when the system is in one of the incompressible states near an IQHE plateau. The noise characteristics detected by the ultra-sensitive charge sensor implanted on the surface of the sample revealed new behaviours not observed in the past. The results can be explained by telegraph noise arising from charge carriers jumping from one localized potential pocket to another, evolving into 1/f noise, as the filling factor shifts away from the centre of the integer state.

description: We present a temperature-dependent photoluminescence study of silicon optical nanocavities formed by introducing point defects into two-dimensional photonic crystals. In addition to the prominent TO-phonon-assisted transition from crystalline silicon at similar to 1.10 eV, we observe a broad defect band luminescence from similar to 1.05 to similar to 1.09 eV. Spatially resolved spectroscopy demonstrates that this defect band is present only in the region where air holes have been etched during the fabrication process. Detectable emission from the cavity mode persists up to room temperature; in strong contrast, the background emission vanishes for T >= 150 K. An Arrhenius-type analysis of the temperature dependence of the luminescence signal recorded either in resonance with the cavity mode or weakly detuned suggests that the higher temperature stability may arise from an enhanced internal quantum efficiency due to the Purcell effect.

Topological modeling for vector graphics
Creators: name: Dalstein, Boris
Publisher: name: University of British Columbia
Year: 2017

description: In recent years, with the development of mobile phones, tablets, and web technologies, we have seen an ever-increasing need to generate vector graphics content, that is, resolution-independent images that support sharp rendering across all devices, as well as interactivity and animation. However, the tools and standards currently available to artists for authoring and distributing such vector graphics content have many limitations. Importantly, basic topological modeling, such as the ability to have several faces share a common edge, is largely absent from current vector graphics technologies. In this thesis, we address this issue with three major contributions. First, we develop theoretical foundations of vector graphics topology, grounded in algebraic topology. More specifically, we introduce the concept of Point-Curve-Surface complex (PCS complex) as a formal tool that allows us to interpret vector graphics illustrations as non-manifold, non-planar, non-orientable topological spaces immersed in R2, unlike planar maps which can only represent embeddings. Second, based on this theoretical understanding, we introduce the vector graphics complex (VGC) as a simple data structure that supports fundamental topological modeling operations for vector graphics illustrations. It allows for the direct representation of incidence relationships between objects, while at the same time keeping the geometric flexibility of stacking-based systems, such as the ability to have edges and faces overlap each others. Third and last, based on the VGC, we introduce the vector animation complex (VAC), a data structure for vector graphics animation, designed to support the modeling of time-continuous topological events, which are common in 2D hand-drawn animation. This allows features of a connected drawing to merge, split, appear, or disappear at desired times via keyframes that introduce the desired topological change. Because the resulting space-time complex directly captures the time-varying topological structure, features are readily edited in both space and time in a way that reflects the intent of the drawing.

description: Deterministic graph grammars generate regular graphs, that form a structural extension of configuration graphs of pushdown systems. In this paper, we study a probabilistic extension of regular graphs obtained by labelling the terminal arcs of the graph grammars by probabilities. Stochastic properties of these graphs are expressed using PCTL, a probabilistic extension of computation tree logic. We present here an algorithm to perform approximate verification of PCTL formulae. Moreover, we prove that the exact model-checking problem for PCTL on probabilistic regular graphs is undecidable, unless restricting to qualitative properties. Our results generalise those of EKM06, on probabilistic pushdown automata, using similar methods combined with graph grammars techniques.

description: We present a systematic experimental investigation of an unusual transport phenomenon observed in two-dimensional (2D) electron gases in Si/SiGe heterostructures under integer quantum Hall effect (IQHE) conditions. This phenomenon emerges under specific experimental conditions and in different material systems. It is commonly referred to as a Hall resistance overshoot but it lacks a consistent explanation so far. Based on our experimental findings, we have developed a model that accounts for all of our observations in the framework of a screening theory for the IQHE. Within this model, the origin of the overshoot is attributed to a transport regime where current is confined to co-existing evanescent incompressible strips of different filling factors.

description: For a minimal inequality derived from a maximal lattice-free simplicial polytope in $\R^n$, we investigate the region where minimal liftings are uniquely defined, and we characterize when this region covers $\R^n$. We then use this characterization to show that a minimal inequality derived from a maximal lattice-free simplex in $\R^n$ with exactly one lattice point in the relative interior of each facet has a unique minimal lifting if and only if all the vertices of the simplex are lattice points.

description: We present a comparative microphotoluminescence study of the emission intensity of self-assembled germanium islands coupled to the resonator mode of two-dimensional silicon photonic crystal defect nanocavities. The cavity-mode intensity is investigated for L3 and hexapole cavities with a range of different mode quality factors. For each type of cavity, many nominally identical samples are probed to obtain reliable statistics. As the cavity-mode quality factor increases, we observe a clear reduction of the average mode emission intensity under conditions of strong optical pumping. This clear trend is compared with simulations based on a dissipative master-equation approach that describes a cavity weakly coupled to an ensemble of emitters. We obtain direct evidence that reabsorption of photons in the cavity is responsible for the observed trend. When combined with the observation of cavity linewidth broadening in power-dependent measurements, we conclude that free carrier absorption limits the cavity-mediated light enhancement under conditions of strong excitation.
“M’apparecchio a squadrare i Portoghesi con molta cura”. Il Portogallo nelle Lettere familiari di Giuseppe Baretti a’ suoi tre fratelli
Creators: name: Abbati, Orietta
Publisher: name: Artifara
Year: 2022

description: Il presente articolo ha per oggetto di studio il testo odeporico di Giuseppe Baretti Lettere Familiari a’ suoi tre Fratelli Filippo, Giovanni e Amedeo, pubblicato in due tomi, (Milano1762, Venezia 1763), successivamente ristampato in Inghilterra, in una versione molto più estesa con il titolo Journey from London to Genoa, through England, Portugal, Spain and France (1770). In particolare l’attenzione si concentra sulle trenta lettere dedicate al Portogallo, dove il viaggiatore piemontese permarrà dal 29 agosto al 22 settembre del 1760. La lettura delle lettere portoghesi è preceduta da una necessaria riflessione sulla problematica classificazione del testo all’interno della letteratura odeporica molto in voga nel XVIII secolo, che tiene conto dei contributi critici di vari specialisti dell’opera dell’autore piemontese (Anglani, Barberi Squarotti, Bigi, Guagnini). Lo studio prosegue con una lettura critica delle lettere relative al Portogallo, in cui si evidenzierà una prevalente postura egotica e individualista del Baretti viaggiatore – narratore che, sempre sul filo dell’ironia e della parodia, spesso con toni burleschi, consegna ai “leggitori” un testo di sicuro interesse descrittivo, ma in cui prevale il suo sguardo critico, polemico, quando non esplicitamente un giudizio negativo, sul regno del Portogallo da lui visitato.

description: We develop the properties of the $n$-th sequential topological complexity $TC_n$, a homotopy invariant introduced by the third author as an extension of Farber's topological model for studying the complexity of motion planning algorithms in robotics. We exhibit close connections of $TC_n(X)$ to the Lusternik-Schnirelmann category of cartesian powers of $X$, to the cup-length of the diagonal embedding $X\hookrightarrow X^n$, and to the ratio between homotopy dimension and connectivity of $X$. We fully compute the numerical value of $TC_n$ for products of spheres, closed 1-connected symplectic manifolds, and quaternionic projective spaces. Our study includes two symmetrized versions of $TC_n(X)$. The first one, unlike Farber-Grant's symmetric topological complexity, turns out to be a homotopy invariant of $X$; the second one is closely tied to the homotopical properties of the configuration space of cardinality-$n$ subsets of $X$. Special attention is given to the case of spheres.

description: We present evidence that electrical transport studies of epitaxial p-type GeMn thin films fabricated on high-resistivity Ge substrates are severely influenced by parallel conduction through the substrate, related to the large intrinsic conductivity of Ge due to its small band gap. Anomalous Hall measurements and large magnetoresistance effects are completely understood by taking a dominating substrate contribution as well as the measurement geometry into account. It is shown that substrate conduction persists also for well-conducting, degenerate, p-type thin films, giving rise to an effective two-layer conduction scheme. Using n-type Ge substrates, parallel conduction through the substrate can be reduced for the p-type epilayers, as a consequence of the emerging pn-interface junction. GeMn thin films fabricated on these substrates exhibit a negligible magnetoresistance effect. Our study underlines the importance of a thorough characterization and understanding of possible substrate contributions for electrical transport studies of GeMn thin films.

description: A detailed Raman characterization of the structural properties of as-grown and annealed self-assembled Si/Ge dot multilayers is reported in this paper. Several new modes in as-grown or annealed Si/Ge dots and a frequency splitting of 4.2 cm(-1) between the longitudinal (LO) and transversal optical (TO) Ge-Ge modes in as-grown Si/Ge dots are observed in Raman spectra. An average Ge content of 0.8 and lateral strain of -3.4% are consistently obtained from these spectral features for as-grown Si/Ge dots with a lateral size of about 20 nm and a height of about 2 nm. It suggests that a certain amount of intermixing between Si spacer layers and Si/Ge dots takes place for the Si/Ge dot multilayers. The annealing behavior of the Ge-Si mode in Si/Ge dots indicates that the observed sharp Ge-Si mode is a Ge-Si alloy mode within the core regions of Si/Ge dots, rather than a Ge-Si interface mode in the interface regions of dots. The phonon strain-shift coefficients of the Ge-Ge and Ge-Si modes are determined for the small-sized Si/Ge dots with a high Ge content under a biaxial strain condition. The results show that the LO-TO frequency splitting of the Ge-Ge mode and the frequencies of the Ge-Ge and Ge-Si modes can be used as an efficient way to determine the average strain and composition in uncorrelated small-sized Si/Ge dot multilayers in which the mean strain field is close to the biaxial case.

description: The Franson interferometer, proposed in 1989 [J. D. Franson, Phys. Rev. Lett. 62:2205-2208 (1989)], beautifully shows the counter-intuitive nature of light. The quantum description predicts sinusoidal interference for specific outcomes of the experiment, and these predictions can be verified in experiment. In the spirit of Einstein, Podolsky, and Rosen it is possible to ask if the quantum-mechanical description (of this setup) can be considered complete. This question will be answered in detail in this paper, by delineating the quite complicated relation between energy-time entanglement experiments and Einstein-Podolsky-Rosen (EPR) elements of reality. The mentioned sinusoidal interference pattern is the same as that giving a violation in the usual Bell experiment. Even so, depending on the precise requirements made on the local realist model, this can imply a) no violation, b) smaller violation than usual, or c) full violation of the appropriate statistical bound. Alternatives include a) using only the measurement outcomes as EPR elements of reality, b) using the emission time as EPR element of reality, c) using path realism, or d) using a modified setup. This paper discusses the nature of these alternatives and how to choose between them. The subtleties of this discussion needs to be taken into account when designing and setting up experiments intended to test local realism. Furthermore, these considerations are also important for quantum communication, for example in Bell-inequality-based quantum cryptography, especially when aiming for device independence.

description: Self-assembled Si/Ge dot multilayers with small, uncorrelated dots fabricated by molecular beam epitaxy in the Stranski-Krastanov growth mode are studied by Raman scattering of folded longitudinal acoustic (FLA) modes. The FLA Raman spectra are analyzed and modeled with respect to mode frequencies and the spectral envelope of mode intensities. The deduced average superlattice properties are consistent with results from atomic force microscopy. The simple Rytov model used for Si/Ge layer structures reproduces very well the frequencies of the FLA modes up to 150 cm(-1). The nonlinearity of phonon dispersion curves in bulk Si for large momenta, however, becomes important for modeling the higher frequencies of observed FLA modes up to 22nd order. The effective dot layer width and an activation energy for thermal intermixing of 2.1+/-0.2 eV are determined from the spectral envelopes of FLA mode intensities of as-grown and annealed Si/Ge dot multilayers.

description: We present here Imitator II, a new version of Imitator, a tool implementing the "inverse method" for parametric timed automata: given a reference valuation of the parameters, it synthesizes a constraint such that, for any valuation satisfying this constraint, the system behaves the same as under the reference valuation in terms of traces, i.e., alternating sequences of locations and actions. Imitator II also implements the "behavioral cartography algorithm", allowing us to solve the following good parameters problem: find a set of valuations within a given bounded parametric domain for which the system behaves well. We present new features and optimizations of the tool, and give results of applications to various examples of asynchronous circuits and communication protocols.

description: Self-diffusion in intrinsic single crystalline germanium was investigated between 429 and 596 degrees C using (70)Ge/(nat)Ge isotope multilayer structures. The diffusivities were determined by neutron reflectometry from the decay of the first and third order Bragg peak. At high temperatures the diffusivities are in excellent agreement with literature data obtained by ion beam sputtering techniques, while considerably smaller diffusion lengths between 0.6 and 4.1 nm were measured. At lower temperatures the accessible range of diffusivities could be expanded to D approximate to 1x10(-25) m(2) s(-1), which is three orders of magnitude lower than the values measured by sputtering techniques. Taking into account available data on Ge self-diffusion, the temperature dependence is accurately described over nine orders of magnitude by a single Arrhenius equation. A diffusion activation enthalpy of 3.13 +/- 0.03 eV and a pre-exponential factor of 2.54x10(-3) m(2) s(-1) for temperatures between 429 and 904 degrees C are obtained. Single vacancies are considered to prevail self-diffusion in Ge over the whole temperature range.

description: Magnetic properties of Ge1-xMnx epitaxial layers with a Mn content of a few percents are substantially influenced by inhomogeneities in the distribution of Mn atoms in the Ge lattice. Depending on the substrate temperature during molecular-beam epitaxial fabrication, apparently cubic, coherent Mn-rich clusters or incoherent precipitates consisting of the hexagonal, intermetallic Mn5Ge3 phase can occur in a defect free, diamond lattice Ge matrix. In this work, we apply synchrotron x-ray diffraction in grazing-incidence geometry to probe the diffuse scattered intensity of the distorted Ge host lattice. Based on a theoretical description of the scattered intensity we derive quantitative information on the lattice mismatch between the Mn inclusions and the Ge lattice, as well as on the average size of the inclusions and the average Mn content within the inclusions.

description: Margin theory provides one of the most popular explanations to the success of \texttt{AdaBoost}, where the central point lies in the recognition that \textit{margin} is the key for characterizing the performance of \texttt{AdaBoost}. This theory has been very influential, e.g., it has been used to argue that \texttt{AdaBoost} usually does not overfit since it tends to enlarge the margin even after the training error reaches zero. Previously the \textit{minimum margin bound} was established for \texttt{AdaBoost}, however, \cite{Breiman1999} pointed out that maximizing the minimum margin does not necessarily lead to a better generalization. Later, \cite{Reyzin:Schapire2006} emphasized that the margin distribution rather than minimum margin is crucial to the performance of \texttt{AdaBoost}. In this paper, we first present the \textit{$k$th margin bound} and further study on its relationship to previous work such as the minimum margin bound and Emargin bound. Then, we improve the previous empirical Bernstein bounds \citep{Maurer:Pontil2009,Audibert:Munos:Szepesvari2009}, and based on such findings, we defend the margin-based explanation against Breiman's doubts by proving a new generalization error bound that considers exactly the same factors as \cite{Schapire:Freund:Bartlett:Lee1998} but is sharper than \cite{Breiman1999}'s minimum margin bound. By incorporating factors such as average margin and variance, we present a generalization error bound that is heavily related to the whole margin distribution. We also provide margin distribution bounds for generalization error of voting classifiers in finite VC-dimension space.

description: At the beginning of our century few scientists paid attention to the phenomenon of inactivation of photosynthesis by high light intensities which was later called photoinhibition. In the period 1925-1950, the idea was established that photoinhibition is a reversible inactivation, determined by light intensity and exposure time, followed by irreversible damage of the photosynthetic apparatus. However, the absence of a uniform terminology demonstrates that photoinhibition was not completely perceived and understood. In 1956, B. Kok gave the first definition of photoinhibition as a photochemical inactivation of pigment complexes.
A three-phase integrated flow-stress framework for process modelling of composite materials

description: An accurate and efficient predictive tool for process modelling of fibre-reinforced polymeric composite materials is highly desirable because of high production cost and substantial risk involved in their manufacturing. Process modelling of composite materials is complex due to multitude of physical and chemical processes such as flow of resin and gaseous volatiles through the fibre-bed, thermochemical changes, and stress development. These phenomena are usually simulated sequentially in a so-called “integrated sub-model” framework. In the sequential method, (i) mapping of the results from one state to another is performed in a tedious and inefficient process, (ii) the concurrent occurrence of resin flow and stress development is ignored, (iii) the history of pressure during the flow regime of processing is relinquished, and (iv) the local spatial and temporal variations in resin gelation is not captured. Incorporating the main steps of process modeling into a unified module that captures the various phenomena in a continuous manner would help overcome the foregoing drawbacks of the sequential approach. In this thesis, a new methodology is presented to integrate the simulation of resin and gas flow and stress development into a unified computational modelling framework. The governing equations are developed for the general case of a composite system that initially is regarded as a three-phase liquid-gas-solid system and, as a consequence of curing, the resin undergoes a transition from a fluid-like state into an elastic solid forming a solid cured composite material. The employed constitutive equations provide a continuous representation of the evolving material behaviour while maintaining consistency with the formulations that are typically used to represent the material at each of the two processing extremes. The model is implemented in a 2D plane strain displacement-velocity-pressure (u-v-P) finite element code developed in MATLAB. Various numerical examples are presented to demonstrate the capability of the Integrated Flow-Stress (IFS) model to predict the flow-compaction and stress development throughout the curing process of thermoset composite materials. The interactive effects of resin flow, gas flow, and stress development are investigated and comparisons are made with the predicted results obtained from the application of the stress model alone.

description: Suppose that $\tilde{G}$ is a connected reductive group defined over a field $k$, and $Γ$ is a finite group acting via $k$-automorphisms of $\tilde{G}$ satisfying a certain quasi-semisimplicity condition. Then the connected part of the group of $Γ$-fixed points in $\tilde{G}$ is reductive. We axiomatize the main features of the relationship between this fixed-point group and the pair $(\tilde{G},Γ)$, and consider any group $G$, not just the $Γ$-fixed points of $\tilde{G}$, satisfying the axioms. (In fact, the axioms do not require $Γ$ to act on all of $\tilde{G}$.) If both $\tilde{G}$ and $G$ are $k$-quasisplit, then we can consider their duals $\tilde{G}^*$ and $G^*$. We show the existence of and give an explicit formula for a natural map from semisimple stable conjugacy classes in $G^*(k)$ to those in $\tilde{G}^*(k)$. If $k$ is finite, then our groups are automatically quasisplit, and our result specializes to give a map from semisimple conjugacy classes in $G^*(k)$ to those in $\tilde{G}^*(k)$. Since such classes parametrize packets of irreducible representations of $G(k)$ and $\tilde{G}(k)$, one obtains a mapping of such packets.
description: v6: Emphasized root data more, reductive groups less. Some results renumbered. v5: Some simplifications and corrections. v4: Generalized and rewritten. For example, $G$ no longer needs to be the group of $\Gamma$-fixed points in $\tilde{G}$, and indeed $\Gamma$ need not act on all of $\tilde{G}$

description: Under defined growth conditions ferromagnetic hexagonal Mn5Ge3 precipitates are formed in cubic Ge1-xMnx epilayers. To study the topotaxial relationship of these nanomagnets we perform x-ray diffraction experiments in coplanar as well as in grazing incidence geometries at synchrotron sources. Additionally, to the well defined topotaxial relation derived for buried nanomagnets deep within the Ge layer, we found an additional class of Mn5Ge3 precipitates very close to the surface, with larger inclusion diameter and several different crystallographic orientations with respect to the buried ones.

Fruit coloration

description: Structural colour arises from the constructive interference of light with a material structured on a lengthscale corresponding to optical wavelengths. This phenomenon is responsible for the appearance of many of the brightest colours in nature and recently the existence of structural colouration in plants has been demonstrated across multiple species. This thesis extends our understanding of the effect speciﬁcally in fruit epidermal tissues, it uses the physical principles underlying structural colour to understand biological development and it extracts design ideas from biological tissues to enhance the optical response of biomimetic materials. In more detail, this thesis reports the optical characteristics and architecture of structural colour in several fruits of the genera Pollia and Viburnum. Previous work showed that the external cells of Pollia condensata fruits have extremely thick cell walls which act as photonic crystals to reﬂect circular polarised light. Here, the spectral and morphological characteristics of photonic cell walls in this and three other Pollia species are reported and it is shown that the unusual right handed circular polarisation reﬂection is apparent in only P. condensata. It is also shown that the occurrence of right circular polarisation is associated with longer wavelength reﬂection. This thesis extends this analysis by demonstrating the use of structural colour to observe the development of thickened cell walls in Pollia condensata and Pollia japonica using optical microscopy. It is shown that during development, cell wall material is built up gradually and with a ﬁxed structural periodicity in both species, and that signiﬁcant cell wall growth occurs in the earliest stages of the long fruit maturation period. In the other genus investigated, structural colour analysis is extended to the fruits of Viburnum tinus and Viburnum davidii and found to arise from layers of globular vesicles in the specialised cell wall. Inspired by these studies, a novel templating technique for reﬂective self-assembled cellulose nanocrystal ﬁlms is described, which mimics the morphology of Pollia cells by successfully introducing a curvature in the photonic multilayer whilst maintaining its optical response. Enhancement of the angular independence of light reﬂected from this curved surface is demonstrated.

Solvability of eigenvalues in jn configurations

description: Eigenvalues of eigenstates in jn configurations (n identical nucle- ons in the j -orbit) are functions of two-body energies. In some cases they are linear combinations of two-body energies whose coe+/-cients are independent of the interaction and are rational non-negative num- bers. It is shown here that a state which is an eigenstate of any two-body interaction has this solvability property. This includes, in particular, any state with spin J if there are no other states with this J in the jn configuration. It is also shown that eigenstates with solvable eigenvalues have definite seniority v and thus, exhibit partial dynamical symmetry.

description: We present a comprehensive study relating the nanostructure of Ge0.95Mn0.05 films to their magnetic properties. The formation of ferromagnetic nanometer-sized inclusions in a defect-free Ge matrix fabricated by low-temperature molecular beam epitaxy is observed down to substrate temperatures T-S as low as 70 degrees C. A combined transmission electron microscopy and electron energy-loss spectroscopy analysis of the films identifies the inclusions as precipitates of the ferromagnetic compound Mn5Ge3. The volume and amount of these precipitates decrease with decreasing T-S. Magnetometry of the films containing precipitates reveals distinct temperature ranges: Between the characteristic ferromagnetic transition temperature of Mn5Ge3 at approximately room temperature and a lower, T-S-dependent blocking temperature T-B the magnetic properties are dominated by superparamagnetism of the Mn5Ge3 precipitates. Below T-B, the magnetic signature of ferromagnetic precipitates with blocked magnetic moments is observed. At the lowest temperatures, the films show features characteristic of a metastable state.

Understanding financial abandoning from a micro perspective: policy responses to promote inclusion in India
Creators: name: MAHADEVA, M.
Publisher: name: Universit� degli studi di Bergamo
Year: 2009

description: Financial inclusion measures initiated in India to contain financial abandonment have hardly taken the demand side factors at grass roots level into consideration. The authorities of implementation, including the Reserve Bank of India, operate under the presumption that the financial inclusion initiatives have trickled down automatically to the lowest administrative unit at village level and have brought respite into the lives of the hitherto financially excluded sections. However, reality on the ground is entirely different and the situation remains unchanged. Since these measures have had hadly any impct on the financially excluded sections of society, the incidence of financial abandonment remains unchanged at the lowest administrative unit. Surprisingly, people at the grass root level are not familiar and have not even heard about the financial inclusion measures. Therefore, it is unrealistic to expect the necessary change to occur in the absence of any financial institution, like commercial bank or cooperative society at lowest administration unit level. Also, the conspicuous absence of rural credit cooperative societies and selfhelp
group organizations has further worsened the situation in rural areas. This paper, besides
identifying the failures of the financial inclusion measures from the perspective of the lowest administrative unit, attempts to bring the demand side factors to the forefront, including the business potential that exists for financial institutions, and effective administration of financial services by the formal financial system and other newly emerged institutions like self-help groups.
