description: We estimate the feeddown contributions from decays of unstable $A = 4$ and $A = 5$ nuclei to the final yields of protons, deuterons, tritons, $^3$He, and $^4$He produced in relativistic heavy-ion collisions at $\sqrt{s_{\rm NN}} > 2.4$ GeV, using the statistical model. The feeddown contribution effects do not exceed 5% at LHC and top RHIC energies due to the large penalty factors involved, but are substantial at intermediate collision energies. We observe large feeddown contributions for tritons, $^3$He, and $^4$He at $\sqrt{s_{\rm NN}} \lesssim 10$ GeV, where they may account for as much as 70% of the final yield at the lower end of the collision energies considered. Sizable ($>10$%) effects for deuteron yields are observed at $\sqrt{s_{\rm NN}} \lesssim 4$ GeV. The results suggest that the excited nuclei feeddown cannot be neglected in the ongoing and future analysis of light nuclei production at intermediate collision energies, including HADES and CBM experiments at FAIR, NICA at JINR, RHIC beam energy scan and fixed-target programmes, and NA61/SHINE at CERN. We further show that the freeze-out curve in the $T$-$μ_B$ plane itself is affected significantly by the light nuclei at high baryochemical potential.

description: We investigate the interacting, one-dimensional Rice-Mele model, a prototypical fermionic model of topological properties. To set the stage, we firstly compute the single-particle spectral function, the local density, and the boundary charge in the absence of interactions. The boundary charge is fully determined by bulk properties indicating a bulk-boundary correspondence. In a large parameter regime it agrees with the one obtained from an effective low-energy theory (arXiv:2004.00463). Secondly, we investigate the robustness of our results towards two-particle interactions. To resum the series of leading logarithms for small gaps, which dismantle plain perturbation theory in the interaction, we use an essentially analytical renormalization group approach. It is controlled for small interactions and can directly be applied to the microscopic lattice model. We benchmark the results against numerical density matrix renormalization group data. The main interaction effect in the bulk is a power-law renormalization of the gap with an interaction dependent exponent. The important characteristics of the boundary charge are unaltered and can be understood from the renormalized bulk properties, elevating the bulk-boundary correspondence to the interacting regime. This requires a consistent treatment not only of the low-energy gap renormalization but also of the high-energy band width one. In contrast to low-energy field theories our renormalization group approach also provides the latter. We show that the interaction spoils the relation between the bulk properties and the number of edge states, consistent with the observation that the Rice-Mele model with finite potential modulation does not reveal any zero-energy edge states.
title: Spatial Adhocism as Practice for Conflict Politics: Theorising Urban Politics in Kolkata
Creators: name: Ray, Raktim
Publisher: name: The Open University
Year: 2020

description: This thesis critically examines how people at the urban margins of Kolkata form various kinds of political relationships with the postcolonial state to exert rights in the city. It considers these relationships as conflict politics and analyses its spatial manifestations through the notion of ‘spatial adhocism’. Spatial adhocism refers to the quasi-permanent state-political society relations for the mobilisation of resources outside legality. The thesis expands upon existing literature to provide new analytical and empirical insights into the discursive socio-spatial subjectivities of postcolonial cities. It does so, by examining how the practices of conflict politics and spatial adhocism are deployed by the postcolonial state and the political society. The thesis also contributes to the understanding of adhoc geographies which exist in postcolonial urbanism. The empirical evidence underpinning this thesis is collected from three illustrative case studies from Kolkata, namely Loomtex jute mill worker’s movement, Salt Lake anti-eviction movement and Bhangar anti-power-grid movement. Methodologically, this thesis adopts an ethnographic approach, particularly semi-structured interviews, document analysis, participant observation. In terms of comparison, this thesis utilises the experimental comparison method of analysing differential patterns of conflict politics and interconnected trajectories of spatial adhocism. The central findings of the thesis are that the relationships between the state and political society are heterogeneous and that spatial adhocism is omnipresent in postcolonial urbanism. Firstly, the thesis challenges the binary relation of dominance and resistance between the state and the political society and establishes the relation as various forms of engagements. Secondly, it shows that spatial adhocism enables political society to practice various forms of conflict politics with the state to alter hegemonic socio-spatial relations. For the postcolonial state adhoc practices limit conflict politics and help it to maintain an ambiguous relationship with people at the urban margins. This ambiguity serves a two-fold aim. It helps the state to promote capital accumulation in a contingent way, and it also promotes a selective allowance of rights for the people at the margins of the state. Overall the thesis claims that postcolonial urbanism can be theorised through an understanding of the heterogeneity of discursive political practices and their spatial manifestations.

description: We have investigated the local magneto-transport in high-quality 2D electron systems at low carrier densities. The positive magneto-resistance in perpendicular magnetic field in the strongly insulating regime has been measured to evaluate the spatial concentration of localized states within a mesoscopic region of the samples. An independent measurement of the electron density within the same region shows an unexpected correspondence between the density of electrons in the metallic regime and that of the localized states in the insulating phase. We have argued that this correspondence manifests a rigid distribution of electrons at low densities.

description: Multilayer graphene with rhombohedral and Bernal stacking are supposed to be metallic, as predicted by density functional theory calculations using semi-local functionals. However recent angular resolved photoemission and transport data have questioned this point of view. In particular, rhombohedral flakes are suggested to be magnetic insulators. Bernal flakes composed of an even number of layers are insulating, while those composed of an odd number of layers are pseudogapped. Here, by systematically benchmarking with plane waves codes, we develop very accurate all-electron Gaussian basis sets for graphene multilayers. We find that, in agreement with our previous calculations, rhombohedral stacked multilayer graphene are gapped for and magnetic. However, the valence band curvature and the details of the electronic structure depend crucially on the basis set. Only substantially extended basis sets are able to correctly reproduce the effective mass of the valence band top at the K point, while the popular POB-TZVP basis set leads to a severe overestimation. In the case of Bernal stacking, we show that exact exchange gaps the flakes composed by four layers and opens pseudogaps for N = 3, 6, 7, 8. However, the gap or pseudogap size and its behaviour as a function of thickness are not compatible with experimental data. Moreover, hybrid functionals lead to a metallic solution for 5 layers and a magnetic ground state for 5, 6 and 8 layers. Magnetism is very weak with practically no effect on the electronic structure and the magnetic moments are mostly concentrated in the central layers. Our hybrid functional calculations on trilayer Bernal graphene multilayers are in excellent agreement with non-magnetic GW calculations. For thicker multilayers, our calculations are a benchmark for manybody theoretical modeling of the low energy electronic structure.

description: This paper contains the latest installment of the authors' project on developing ensemble based data assimilation methodology for high dimensional fluid dynamics models. The algorithm presented here is a particle filter that combines model reduction, tempering, jittering, and nudging. The methodology is tested on a two-layer quasi-geostrophic model for a $β$-plane channel flow with $O(10^6)$ degrees of freedom out of which only a minute fraction are noisily observed. The model is reduced by following the stochastic variational approach for geophysical fluid dynamics introduced in Holm (Proc Roy Soc A, 2015) as a framework for deriving stochastic parametrisations for unresolved scales. The reduction is substantial: the computations are done only for $O(10^4)$ degrees of freedom. We introduce a stochastic time-stepping scheme for the two-layer model and prove its consistency in time. Then, we analyze the effect of the different procedures (tempering combined with jittering and nudging) on the performance of the data assimilation procedure using the reduced model, as well as how the dimension of the observational data (the number of "weather stations") and the data assimilation step affect the accuracy and uncertainty of the results.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this note we present a little Higgs model that has custodial SU(2) as an approximate symmetry. This theory is a simple modification of the ``Minimal Moose'' with SO(5) global symmetries protecting the Higgs mass. This allows for a simple limit where TeV physics makes small contributions to precision electroweak observables. The spectrum of particles and their couplings to Standard Model fields are studied in detail. At low energies this model has two Higgs doublets and it favours a light Higgs from precision electroweak bounds, though for different reasons than in the Standard Model. The limit on the breaking scale, f, is roughly 700 GeV, with a top partner of 2 TeV, W' and B' of 2.5 TeV, and heavy Higgs partners of 2 TeV. These particles are easily accessible at hadron colliders.

title: The Impact of Participating in British Counterinsurgency Campaigns on British Armed Forces Personnel: The Malayan Emergency as a Case-Study
Creators: name: Probert, Thomas
Publisher: name: The Open University
Year: 2021

description: The end of the Second World War saw a retreat from empire and a period of decolonisation. During this time Britain’s military became embroiled in a series of protracted counterinsurgency campaigns. Counterinsurgency engendered a different set of concerns and stresses than the previous world war, not least that operations took place under a set of Emergency Regulations that purported to control the use of force. The longest running of these campaigns was in Malaya where a State of Emergency was declared in 1948 and did not officially end until 1960. Using the Malayan Emergency as a case study, this thesis will investigate the immediate and long-term psychological impact of participation in Britain’s postwar counterinsurgency campaigns on its service personnel. In order to understand impact, this thesis will employ two main concepts: resilience and psychopathology. It will suggest that morale was an earlier analogue of resilience. It will argue that training, which privileged the use of force, was used to instil morale in service personnel and that regimental culture reinforced and sustained morale while on operations. This thesis will then go on to look at when resilience, or morale, gave way to breakdowns. Within the history of military psychiatry, the psychopathological conditions seen during war were largely thought of in terms of predisposition or weakness. This would change in the aftermath of the Vietnam War, with the creation of the diagnostic category, Post-Traumatic Stress Disorder. PTSD shifted the emphasis away from predisposition toward the traumatic event and reduced the stigma surrounding mental illness. At the time of the Malayan Emergency, however, service personnel were subject to a culture that expected resilience. Finally, then, this thesis, will argue that stigma had an immediate and ongoing effect on whether symptoms were reported.

description: The notion of memory capacity, originally introduced for echo state and linear networks with independent inputs, is generalized to nonlinear recurrent networks with stationary but dependent inputs. The presence of dependence in the inputs makes natural the introduction of the network forecasting capacity, that measures the possibility of forecasting time series values using network states. Generic bounds for memory and forecasting capacities are formulated in terms of the number of neurons of the nonlinear recurrent network and the autocovariance function or the spectral density of the input. These bounds generalize well-known estimates in the literature to a dependent inputs setup. Finally, for the particular case of linear recurrent networks with independent inputs it is proved that the memory capacity is given by the rank of the associated controllability matrix, a fact that has been for a long time assumed to be true without proof by the community.

description: Nigerian Extension Services have experienced so many changes and reorganizations within the last century. These changes have not brought any significant contribution to agricultural production in the country. This situation has left a puzzle as to why Nigerian agriculture still remain traditional and fails to witness any scientific transformation. This paper therefore reviews the various reorganizations of agricultural Extension Services in Nigeria and throws light on specific changes that have occurred and their implications on the effectiveness of. the country's agricultural Extension Services.

description: The problem of maintaining gauge invariance when truncating the two particle irreducible (2PI) effective action has been studied recently by several authors. Here we give a simple and very general derivation of the gauge dependence identities for the off-shell 2PI effective action. We consider the case where the gauge is fixed by an arbitrary function of the quantum gauge field, subject only to the restriction that the Faddeev-Popov matrix is invertable. We also study the background field gauge. We address the role that these identies play in solving gauge invariance problems associated with physical quantities calculated using a truncated on-shell 2PI effective action.

description: Lithium abundances are presented for 91 dwarf and subgiant stars in the Galactic bulge. The analysis is based on line synthesis of the 7Li line at 6707 Å in high-resolution spectra obtained during gravitational microlensing events, when the brightnesses of the targets were highly magnified. Our main finding is that the bulge stars at sub-solar metallicities, and that are older than about eight billion years, does not show any sign of Li production, that is, the Li trend with metallicity is flat (or even slightly declining). This indicates that no lithium was produced during the first few billion years in the history of the bulge. This finding is essentially identical to what is seen for the (old) thick disk stars in the Solar neighbourhood, and adds another piece of evidence for a tight connection between the metal-poor bulge and the Galactic thick disk. For the bulge stars younger than about eight billion years, the sample contains a group of stars at very high metallicities at [Fe/H]~+0.4 that have lithium abundances in the range A(Li)=2.6-2.8. In the Solar neighbourhood the lithium abundances have been found to peak at a A(Li)~3.3 at [Fe/H]~ +0.1 and then decrease by 0.4-0.5 dex when reaching [Fe/H]~+0.4. The few bulge stars that we have at these metallicities, seem to support this declining A(Li) trend. This could indeed support the recent claim that the low A(Li) abundances at the highest metallicities seen in the Solar neighbourhood could be due to stars from the inner disk, or the bulge region, that have migrated to the Solar neighbourhood.

Female beauty in Tanizaki Jun’ichirō’s interpretation based on his essay “Love and sensuality”

description: This article is about the subject of female beauty in Tanizaki Jun’ichirō’s interpretation based on his essay “Love and sensuality” (恋愛及び色情) that shows how Tanizaki’s views on aesthetics changed from the late 1920s. The essay was published in parts in women’s magazine Fujin kōron (婦人公論) from April to June 1931. It was a kind of Tanizaki Jun’ictirō’s manifesto on the difference in aesthetic norms between East and West, the aim of which was to rid Japanese women of their physiological inferiority complex, the habits of copying Western women and to compare themselves with them. Tanizaki considered that there should be other rules for Japanese women: he introduced new standards for assessing their beauty, such as smoothness of skin, its color and iroke (色気). One condition for the appearance of the essay can be the rise of anti-Western sentiment in Japan in the 1930s, which was in part caused by xenophobia and discrimination of the Japanese by Western people on a racial basis. Tanizaki Jun’ichirō directed his efforts at overcoming the complex of female physiological inferiority, stating that Japanese women have a number of significant advantages over the European.
Статья посвящена женской красоте в трактовке писателя Танидзаки Дзюнъитиро на материале эссе «Любовь и сладострастие» (Рэнъай оёби сикидзё:, 恋愛及び色情), которое раскрывает изменившиеся в конце 20-х годов ХХ века взгляды писателя на эстетику. Оно публиковалось частями в женском журнале Фудзин ко:рон (婦人公論) с апреля по июнь 1931 года и явилось своего рода манифестом писателя о разнице эстетических установок между Западом и Востоком, целью которого было избавление японских женщин от комплекса телесной неполноценности, привычек копировать повадки западных женщин и сравнивать себя с ними. Танидзаки полагал, что в отношении японских женщин должны действовать иные правила: он ввёл новые параметры оценки их красоты, такие, как гладкость кожи, её цвет и «ирокэ» (色気). Одной из предпосылок к появлению эссе можно назвать разгар антизападных настроений в Японии в 30-е годы, причиной которых послужили, в том числе ксенофобия и дискриминация японцев со стороны западного человека по расовому признаку. Танидзаки Дзюнъитиро направил свои усилия на преодоление комплекса женской телесной неполноценности – японская женщина имеет ряд существенных преимуществ над европейской.

description: We report the detection of a new satellite of M31, projected close to M32. And VIII is tidally distorted, with length ~10 kpc and width a few kpc. It contains 5-12 planetary nebulae (PNe) and 1-3 globular clusters, and has a velocity of -204 km/s with respect to M31, some 350 km/s away from M32's velocity. There are also about 4 x 10^5 solar masses of HI, well-separated from the disk, at the same position and velocity. The satellite has luminosity of 1.2-2.4 x 10^8 solar luminosities, and a central surface brightness of order μ_V=24. Both these values are typical of Local Group dwarf galaxies. Its surface brightness is some 6 magnitudes brighter than any of the stellar streams found in the Milky Way or M31. The three associated globular clusters have reddening consistent with foreground reddening from the Milky Way only, making it likely that the satellite is in front of M31, unlike the giant tidal stream of Ibata et al.(2001), which is behind M31 in the SE quadrant. However, the major axis of And VIII is aligned with the western edge of this giant stream, and we suggest that its unusual fan shape is caused by superposition of two streams, the westernmost of which was tidally stripped from And VIII.

description: The natural orbital functional theory (NOFT) has emerged as an alternative formalism to both density functional (DF) and wavefunction methods. In NOFT, the electronic structure is described in terms of the natural orbitals (NOs) and their occupation numbers (ONs). The approximate NOFs have proven to be more accurate than those of the density for systems with a significant multiconfigurational character, on one side, and scale better with the number of basis functions than correlated wavefunction methods, on the other side. A challenging task in NOFT is to efficiently perform orbital optimization. In this article we present DoNOF, our open source implementation based on diagonalizations that allows to obtain the resulting orbitals automatically orthogonal. The one-particle reduced-density matrix (1RDM) of the ensemble of pure-spin states provides the proper description of spin multiplets. The capabilities of the code are tested on the water molecule, namely, geometry optimization, natural and canonical representations of molecular orbitals, ionization potential, and electric moments. In DoNOF, the electron-pair-based NOFs developed in our group PNOF5, PNOF7 and PNOF7s are implemented. These JKL-only NOFs take into account most non-dynamic effects plus intrapair-dynamic electron correlation, but lack a significant part of interpair-dynamic correlation. Correlation corrections are estimated by the single-reference NOF-MP2 method that simultaneously calculates static and dynamic electron correlations taking as a reference the Slater determinant formed with the NOs of a previous PNOF calculation. The NOF-MP2 method is used to analyze the potential energy surface (PES) and the binding energy for the symmetric dissociation of the water molecule, and compare it with accurate wavefunction-based methods.

description: We present a direct experimental measurement of an effective temperature in a colloidal glass of Laponite, using a micrometric bead as a thermometer. The nonequilibrium fluctuation-dissipation relation, in the particular form of a modified Einstein relation, is investigated with diffusion and mobility measurements of the bead embedded in the glass. We observe an unusual non-monotonic behavior of the effective temperature : starting from the bath temperature, it is found to increase up to a maximum value, and then decreases back, as the system ages. We show that the observed deviation from the Einstein relation is related to the relaxation times previously measured in dynamic light scattering experiments.

Digitaler Zwilling
Hydrochemische Modellierung

description: Im MALEG Verbundprojekt wird an der Effizienzsteigerung von geothermischer Energieproduktion mit Hilfe von künstlicher Intelligenz geforscht. In diesem Zusammenhang wird sowohl ein Digitaler Zwilling des Geothermiekraftwerks, mit dessen Sensoren und Aktoren, als auch ein Digitaler Zwilling der hydrogeochemischen Prozesse innerhalb des Thermalwasserkreislaufes entwickelt. 
Die Energieproduktion in Geothermiekraftwerken ist an die hydrochemischen Grundbedingungen des Fluides geknüpft. Dabei wird durch Druck-, Temperatur-, oder pH-Änderungen das chemische Gleichgewicht des geförderten Thermalwassers verändert, welches zu unkontrollierten Prozessen wie Mineralausfällungen, Ausgasen und Korrosion führen können. Um diese Prozesse besser abbilden zu können, wurde ein Digitaler Zwilling entwickelt. Dieser Zwilling basiert auf der Kopplung eines geochemischen Modellierprogramms (IPhreeqc) und eines numerischen Berechnungsprogramms (MATLAB) via Component Object Model Servers. Dabei werden Modellierungen automatisiert berechnet, übertragen und ausgewertet. Somit lassen sich die neuen geochemischen Gleichgewichtsverhältnisse durch die Parameteränderung direkt ermitteln und interpretieren. Diese Ergebnisse bilden die Grundlade für die Implementierung einer Künstlichen Intelligenz zur Effizienzsteigerung von Geothermiekraftwerken.

description: We study the transition form factors between pseudoscalar and vector mesons using a covariant fermion field theory model in $(3+1)$ dimensions. Performing the light-front calculation in the $q^+ =0$ frame in parallel with the manifestly covariant calculation, we note that the suspected nonvanishing zero-mode contribution to the light-front current $J^+$ does not exist in our analysis of transition form factors. We also perform the light-front calculation in a purely longitudinal $q^+ > 0$ frame and confirm that the form factors obtained directly from the timelike region are identical to the ones obtained by the analytic continuation from the spacelike region. Our results for the $B \to D^* l ν_l$ decay process satisfy the constraints on the heavy-to-heavy semileptonic decays imposed by the flavor independence in the heavy quark limit.

description: We show that temporal shape modulations (pumping) of a quantum dot in the presence of spin-orbital coupling lead to a finite dc spin current. Depending on the strength of the spin-orbit coupling, the spin current is polarized perpendicular to the plane of the two-dimensional electron gas, or has an arbitrary direction subject to mesoscopic fluctuations. We analyze the statistics of the spin and charge currents in the adiabatic limit for the full cross-over from weak to strong spin-orbit coupling.

CFD Analysis of Solar Air Heater having Ribs - A Critical Review
Creators: name: Md Sharique Kamal
Publisher: name: Zenodo

description: Solar energy is radiation from the sun that can produce heat, cause chemical processes, or generate electricity. The entire amount of solar energy that reaches the Earth is far greater than the energy needs of the world today and in the future. The amount of solar energy that the Earth receives each day is around 200,000 times greater than the total amount of electricity that is generated around the world in a day. This means that solar energy has a huge potential. Solar cells are capable of converting solar light directly into electricity. When light hits the junction between a metal and a semiconductor (like silicon) or the junction between two separate semiconductors, a modest electric potential is produced in these types of cells. The current study work examines the thermal performance of solar air heaters and how it might be improved through the use of artificial roughness. The study found that artificial roughness definitely enhances the efficacy of solar air heaters.

description: Cosmic voids are a key component of the large-scale structure that contain a plethora of cosmological information. Typically, voids are identified from the underlying galaxy distribution, which is a biased tracer of the total matter field. Previous works have shown that 2D voids identified in weak lensing maps -- weak lensing voids -- correspond better to true underdense regions along the line of sight. In this work, we study how the properties of weak lensing voids depend on the choice of void finder, by adapting several popular void finders. We present and discuss the differences between identifying voids directly in the convergence maps, and in the distribution of weak lensing peaks. Particular effort has been made to test how these results are affected by galaxy shape noise, which is a dominant source of noise in weak lensing observations. By studying the signal-to-noise ratios (SNR) for the tangential shear profile of each void finder, we find that voids identified directly in the convergence maps have the highest SNR but are also the ones most affected by galaxy shape noise. Troughs are least affected by noise, but also have the lowest SNR. The tunnel algorithm, which identifies voids in the distribution of weak lensing peaks, represents a good compromise between finding a large tangential shear SNR and mitigating the effect of galaxy shape noise.

description: Addressing the need for progressive change in our industry, this thesis argues that it is integral to bring the concept of designing for manufacturing and assembly (DfMA) into our professional discourse. Deconstructing the erosion of our design integrity from three traditionally undervalued phases of a project—Design Development, Construction Documentation, and Tendering—this thesis proposes that by collectively fostering an “Industrialized Ecosystem”, we can democratize industrialized processes to strengthen the integrity of our work.

description: We investigate how a protoplanetary disc's susceptibility to gravitational instabilities and fragmentation depends on the mass of its host star. We use 1D disc models in conjunction with 3D SPH simulations to determine the critical disc-to-star mass ratios at which discs become unstable against fragmentation, finding that discs become increasingly prone to the effects of self-gravity as we increase the host star mass. The actual limit for stability is sensitive to the disc temperature, so if the disc is optically thin stellar irradiation can dramatically stabilise discs against gravitational instability. However, even when this is the case we find that discs around $2$M$_{\odot}$ stars are prone to fragmentation, which will act to produce wide-orbit giant planets and brown dwarfs. The consequences of this work are two-fold: that low mass stars could in principle support high disc-to-star mass ratios, and that higher mass stars have discs that are more prone to fragmentation, which is qualitatively consistent with observations that favour high-mass wide-orbit planets around higher mass stars. We also find that the initial masses of these planets depends on the temperature in the disc at large radii, which itself depends on the level of stellar irradiation.

description: The safe containment of coal combustion residual (CCR) in landfills was addressed by the U.S. Environment Protection Agency (EPA) CCR rule published in 2015. The new rule affects new and existing U.S. based CCR landfills in terms of implementing safeguard systems for safe disposal and contamination control. Electrical resistivity tomography (ERT) and multichannel analysis of surface waves (MASW) data were acquired across and in proximity to a CCR landfill in southwest Missouri, USA, with the intent to identify potential karst features and seepage pathways.Electrical resistivity tomography data were acquired using an automated 8- channel resistivity meter and multichannel analysis of surface waves data were acquired using a 24-channel Seistronix engineering seismograph and 4.5 Hz geophones. MASW data were acquired to aid the ERT data interpretation by providing engineering properties of subject materials. The outcome from the ERT survey were a suite of 2D and 3D resistivity images. ERT investigates the subsurface to a depth of approximately 100 ft. The outcome from the MASW survey were a suite of 1-D and 2-D (depth vs. shear wave velocity) profiles. MASW investigates the subsurface to a depth of approximately 100 ft. The variations in top-of-rock, variations in moisture content of the CCR, soil and bedrock, and seepage pathways and flow patterns, were successfully mapped.The findings of this research indicate that the seepage pathways in close proximity to the landfill are from surface run-off and do not pose a threat to groundwater, and no evidence of karst features that could affect the structure stability of the CCR landfill in close proximity to and underneath the site was found

description: Mergers and acquisitions as a base for many corporative strategies are huge shalenges and opportunites for marketing managers, having in mind their enormous potential for synergy gains and profit for shareholders. At the same time, they are unique opportunity to focus on customers in a much wider and more integral manner. Market share gaining, brand identification, more powerful and diversed product and service lines, development of distribution channels, atractive market penetration, cross selling, enlarged customer base and other motives for mergers and acquisitions are the base for marketing concept incorporation and marketing based synergies. In that sense marketing management becomes critical factor for successful mergers or acquisitions.

description: Electrical Impedance Tomography (EIT) is an emerging non-invasive medical imaging modality. It is based on feeding electrical currents into the patient, measuring the resulting voltages at the skin, and recovering the internal conductivity distribution. The mathematical task of EIT image reconstruction is a nonlinear and ill-posed inverse problem. Therefore any EIT image reconstruction method needs to be regularized, typically resulting in blurred images. One promising application is stroke-EIT, or classification of stroke into either ischemic or hemorrhagic. Ischemic stroke involves a blood clot, preventing blood flow to a part of the brain causing a low-conductivity region. Hemorrhagic stroke means bleeding in the brain causing a high-conductivity region. In both cases the symptoms are identical, so a cost-effective and portable classification device is needed. Typical EIT are not optimal for stroke-EIT because of blurriness. This paper explores the possibilities of machine learning in improving the classification results. Two paradigms are compared: (a) learning from the EIT data, that is Dirichlet-to-Neumann (DN) maps and (b) extracting robust features from data and learning from them. The features of choice are Virtual Hybrid Edge Detection (VHED) functions [Greenleaf {\it et al.}, Analysis \& PDE 11, 2018] that have a geometric interpretation and whose computation from EIT data does not involve calculating a full image of the conductivity. We report the measures of accuracy, sensitivity and specificity of the networks trained with EIT data and VHED functions separately. Computational evidence based on simulated noisy EIT data suggests that the regularized grey-box paradigm (b) leads to significantly better classification results than the black-box paradigm (a).
