description: We study the decoherence of massive fields during inflation based on the Zurek's density matrix approach. With the cubic interaction between inflaton and massive fields, the reduced density matrix for the massive fields can be calculated in the Schrödinger picture which is related to the variance of the non-Gaussian exponent in the wave functional. The decoherence rate is computed in the one-loop form from functional integration. For heavy fields with $m\gtrsim \mathcal{O}(H)$, quantum fluctuations will easily stay in the quantum state and decoherence is unlikely. While for light fields with mass smaller than $\mathcal{O}(H)$, quantum fluctuations are easily decohered within $5\sim10$ e-folds after Hubble crossing. Thus heavy fields can play a key role in studying problems involving inflationary quantum information.

description: A characteristic particle method for the simulation of first order macroscopic traffic models on road networks is presented. The approach is based on the method "particleclaw", which solves scalar one dimensional hyperbolic conservations laws exactly, except for a small error right around shocks. The method is generalized to nonlinear network flows, where particle approximations on the edges are suitably coupled together at the network nodes. It is demonstrated in numerical examples that the resulting particle method can approximate traffic jams accurately, while only devoting a few degrees of freedom to each edge of the network.

Business models to involve Stakeholders in Smart City Projects
Creators: name: Perumal, Uma
Publisher: name: Zenodo
Year: 2024

description: The Smart City projects are visionary projects implemented by the Governments of respective countries. These projects are capital intensive and requires the stakeholders- the Government, the project promoter and the user or the citizen using the facility. Capital intense projects recover the money involved from the user, that makes him the sole spender for the entire project. This paper suggests the idea to make the user an involver than simple spender. Ideas like smart credit points trading among other users, smart credit points transfer earned by sharing individual resources with the community and utilities or facilities for need sharing or trading with the community can bring down the expenses of a single user and help the community as a whole.

description: Enargite (Cu3AsS4) and tennantite (Cu12As4S13) are typical As-bearing sulfides in intermediate-and high-sulfidation epithermal deposits. Trace and major element variations in enargite and tennantite and their substitution mechanisms are widely described. However, Raman spectra of the minerals with correlative quantitative chemical information are rarely documented, especially for enargite. Therefore, comparative electron and μ-Raman microprobe analyses were performed on enargite and fahlore grains. These spectra can be used in the industrial detection and subsequent removal of As-bearing sulfides prior to ore beneficiation in order to diminish the environmental impact of the metallurgical technologies. A simple Sb5+-As5+ substitution in enargite was confirmed by Raman analyses. Similarly, a complete solid solution series from tetrahedrite to tennantite (i.e., Sb3+-As3+ substitution) can be correlated with a gradual evolution in their Raman spectra. In turn, Te4+ occupies the As3+ and Sb3+ sites in fahlore by the coupled substitution Te4+gCu+g(As, Sb)3+g(Cu, Fe, Zn)2+. Accordingly, Raman bands of goldfieldite (Te-rich member) are strongly broadened compared with those of tetrahedrite and tennantite. A secondary phase with high porosity and a fibrous or wormlike texture was found in enargite in a weathered sample. The chemical composition, Raman spectrum, and X-ray diffraction signature of the secondary phase resemble tennantite. A gradual transformation of the primary enargite into this secondary phase was visualized by comparative electron and Raman microprobe mapping.

description: Fundamental diagrams of vehicular traffic flow are generally multi-valued in the congested flow regime. We show that such set-valued fundamental diagrams can be constructed systematically from simple second order macroscopic traffic models, such as the classical Payne-Whitham model or the inhomogeneous Aw-Rascle-Zhang model. These second order models possess nonlinear traveling wave solutions, called jamitons, and the multi-valued parts in the fundamental diagram correspond precisely to jamiton-dominated solutions. This study shows that transitions from function-valued to set-valued parts in a fundamental diagram arise naturally in well-known second order models. As a particular consequence, these models intrinsically reproduce traffic phases.

description: Urban areas across the globe are grappling with the escalating challenges posed by the surge in urbanization, resulting in a surge in the frequency, complexity, and multifaceted nature of urban flood incidents. This phenomenon has been vividly exemplified by recent events in diverse regions such as America, Australia, Brazil, Pakistan, Scotland, Sri Lanka, and the United Kingdom (Jha et al., 2012; Coates, 2010). The impact is not confined to developed nations; African cities like Accra in Ghana, Kano in Nigeria, Kampala in Uganda, Maputo in Mozambique, Bujumbura in Burundi, and Nairobi in Kenya have also witnessed severe flooding episodes (Tucci, 2007; ILGS & IWMI, 2012).

The manifestation of this crisis in Mavoko, within the broader Nairobi Metropolis, is particularly evident during the rainy seasons (March-June and October-December). Similar to urban areas globally, even moderate storms during these periods trigger heightened runoff and escalate flooding incidents (Amnesty International, 2009; Werritty et al., 2007). This study delves into the dynamics of urban flooding in Mavoko, examining its causes, impacts, and potential mitigation strategies.

The research employs a comprehensive approach, integrating insights from previous studies on urban flooding and drawing parallels with global experiences. By elucidating the factors contributing to urban flooding in Mavoko, this study aims to contribute to the broader understanding of urban flood dynamics. The multifaceted nature of the issue demands a nuanced analysis that considers both local and global perspectives.

Key findings highlight the need for proactive and context-specific measures to address urban flooding in Mavoko. The study identifies vulnerabilities in current urban planning, drainage systems, and emergency response mechanisms. Moreover, it explores the socio-economic implications of recurrent flooding, emphasizing the disproportionate impact on marginalized communities

description: We explore a new horizon of modified gravity from the viewpoint of the particle physics. As a concrete example, we take the $F(R)$ gravity to raise a question: can a scalar particle ("scalaron") derived from the $F(R)$ gravity be a dark matter candidate? We place the limit on the parameter in a class of $F(R)$ gravity model from the constraint on the scalaron as a dark matter. The role of the screening mechanism and compatibility with the dark energy problem are addressed.

description: The Aim of this study to assess 20/80 condominium housing projects in Addis Ababa: Researcher used quantitative and qualitative approach as a methodology to address the research questions. Data were collected through a semi-structured questionnaire distributed to 106 selected respondents, with 8 key informant interviews conducted and secondary data was collected from AAHPO employees and Akaki-kalitykoye-feche project sites one and two. The data collected were analyzed using both quantitative and qualitative approaches. The technique used to analyze data was frequency and percentage. The findings indicated that,regarding to the client or public agent such as problem in selection of competent consultants and reliable contractors, absence of good methods and systems in purchasing and finance, slow speed in decision making, poor planning and controlling, lack of leadership skills of project manager, poor coordination and communication with stakeholders, and lack of sense of ownership. Regarding to the consultant, there is lack of knowledge and experience, poor management, and difficulty in controlling contractors, poor coordination and communication with the project stakeholders, a slow response regarding testing and inspection, lack of commitment to confirm construction work according to specification and design. Depending on the contractors' lack of experience and technical profession, poor planning and scheduling, Insufficient coordination and communication, lack of leadership quality, less commitment, wastage of resources around the project sites, construction mistakes and defective works. It suggested thatthe government should pay special attention in facilitating a comprehensive national housing policy by providing land, funds, discounted interest rate, and infrastructures to allow the private sector and the individual citizens to solve the housing deficit.
A measurement of the calorimeter response to single hadrons and determination of the jet energy scale uncertainty using LHC Run-1 $pp$-collision data with the ATLAS detector

Year: 2016
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A measurement of the calorimeter response to isolated charged hadrons in the ATLAS detector at the LHC is presented. This measurement is performed with 3.2 nb$^{-1}$ of proton--proton collision data at $\sqrt{s}=7$ TeV from 2010 and 0.1 nb$^{-1}$ of data at $\sqrt{s}=8$ TeV from 2012. A number of aspects of the calorimeter response to isolated hadrons are explored. After accounting for energy deposited by neutral particles, there is a 5\% discrepancy in the modelling, using Geant4 physics lists, of the calorimeter response to isolated charged hadrons in the central calorimeter region. The description of the response to anti-protons at low momenta is found to be improved with respect to previous analyses. The electromagnetic and hadronic calorimeters are also examined separately, and the detector simulation is found to describe the response in the hadronic calorimeter well. The jet energy scale uncertainty and correlations in scale between jets of different momenta are derived based on these studies. The uncertainty is 2--5\% for jets with transverse momenta above 2 TeV, where this method provides the jet energy scale uncertainty for ATLAS.

description: We present a simple method to solve spherical harmonics moment systems, such as the the time-dependent $P_N$ and $SP_N$ equations, of radiative transfer. The method, which works for arbitrary moment order $N$, makes use of the specific coupling between the moments in the $P_N$ equations. This coupling naturally induces staggered grids in space and time, which in turn give rise to a canonical, second-order accurate finite difference scheme. While the scheme does not possess TVD or realizability limiters, its simplicity allows for a very efficient implementation in Matlab. We present several test cases, some of which demonstrate that the code solves problems with ten million degrees of freedom in space, angle, and time within a few seconds. The code for the numerical scheme, called StaRMAP (Staggered grid Radiation Moment Approximation), along with files for all presented test cases, can be downloaded so that all results can be reproduced by the reader.

description: From a sample of spectra of 439 white dwarfs (WDs) from the ESO-VLT Supernova-Ia Progenitor surveY (SPY), we measure the maximal changes in radial-velocity (DRVmax) between epochs (generally two epochs, separated by up to 470d), and model the observed DRVmax statistics via Monte-Carlo simulations, to constrain the population characteristics of double WDs (DWDs). The DWD fraction among WDs is fbin=0.100+/-0.020 (1-sigma, random) +0.02 (systematic), in the separation range ~<4AU within which the data are sensitive to binarity. Assuming the distribution of binary separation, a, is a power-law, dN/da ~ a^alpha, at the end of the last common-envelope phase and the start of solely gravitational-wave-driven binary evolution, the constraint by the data is alpha=-1.3+/-0.2 (1-sigma) +/-0.2 (systematic). If these parameters extend to small separations, the implied Galactic WD merger rate per unit stellar mass is R_merge=(1-80)e-13 /yr/Msun (2-sigma), with a likelihood-weighted mean of R_merge=(7+/-2)e-13 /yr/Msun (1-sigma). The Milky Way's specific Type-Ia supernova (SN Ia) rate is likely R_Ia~1.1e-13 /yr/Msun and therefore, in terms of rates, a possibly small fraction of all merging DWDs (e.g. those with massive-enough primary WDs) could suffice to produce most or all SNe Ia.

description: We experimentally study gravity-capillary wave turbulence on the interface between two immiscible fluids of close density with free upper surface. We locally measure the wave height at the interface between both fluids by means of a highly sensitive laser Doppler vibrometer. We show that the inertial range of the capillary wave turbulence regime is significantly extended when the upper fluid depth is increased: The crossover frequency between the gravity and capillary wave turbulence regimes is found to decrease whereas the dissipative cut-off frequency of the spectrum is found to increase. We explain these observations by the progressive decoupling between waves propagating at the interface and the ones at the free surface, using the full dispersion relation of gravity-capillary waves in a two-layer fluid of finite depths. The cut-off evolution is due to the disappearance of parasitic capillaries responsible for the main wave dissipation for a single fluid.

description: Contexte. Le retrait dès que possible du cathéter veineux périphérique (CVP) ainsi que la réévaluation quotidienne de son maintien sont recommandés. Objectif et méthode. Nous avons évalué l’application de ces mesures, en 2017 et 2019, par la réalisation d’une analyse de la pertinence du maintien des CVP non utilisés, complétée en 2019 par un audit observationnel plus large de la gestion des CVP. Deux séries de formations professionnelles ont été organisées selon une approche pédagogique différente. Résultats. Les résultats portent sur 402 CVP en 2017 et 362 en 2019 correspondant à 389 patients en 2017 (38,5%) et 341 (31,5%) en 2019 porteurs d’au moins un CVP (p<0,001). La proportion de CVP non utilisés sans argumentation du maintien est stable entre 2017 et 2019 (8,2% vs 9,4%). La première formation sur les indications des CVP non utilisés a permis de sensibiliser les soignants de la majorité des services. Organisée après l’enquête de 2019, une nouvelle formation obligatoire a concerné 735 professionnels. Elle a comporté la simulation d’une pose de CVP au cours de laquelle sont abordées les recommandations de 2019 de la Société française d’hygiène hospitalière. Bien que la fréquence des CVP non utilisés et non justifiés soit comparable en 2017 et 2019, la diminution significative du nombre de patients porteurs de CVP suggère leur retrait plus précoce en 2019, donc une amélioration de l’évaluation de leur maintien. Conclusion. Ces études permettent d’identifier des axes d’amélioration des pratiques soignantes et de former in situ la majorité des professionnels concernés par la gestion des CVP. L’impact de cette stratégie pédagogique originale sera évalué par une nouvelle enquête de pertinence et par la surveillance des bactériémies associées aux CVP.

description: It is natural to investigate if the quantization of an integrable or superintegrable classical Hamiltonian systems is still integrable or superintegrable. We study here this problem in the case of natural Hamiltonians with constants of motion quadratic in the momenta. The procedure of quantization here considered, transforms the Hamiltonian into the Laplace-Beltrami operator plus a scalar potential. In order to transform the constants of motion into symmetry operators of the quantum Hamiltonian, additional scalar potentials, known as quantum corrections, must be introduced, depending on the Riemannian structure of the manifold. We give here a complete geometric characterization of the quantum corrections necessary for the case considered. Stäckel systems are studied in particular details. Examples in conformally and non-conformally flat manifolds are given.

description: The Aw-Rascle-Zhang (ARZ) model can be interpreted as a generalization of the Lighthill-Whitham-Richards (LWR) model, possessing a family of fundamental diagram curves, each of which represents a class of drivers with a different empty road velocity. A weakness of this approach is that different drivers possess vastly different densities at which traffic flow stagnates. This drawback can be overcome by modifying the pressure relation in the ARZ model, leading to the generalized Aw-Rascle-Zhang (GARZ) model. We present an approach to determine the parameter functions of the GARZ model from fundamental diagram measurement data. The predictive accuracy of the resulting data-fitted GARZ model is compared to other traffic models by means of a three-detector test setup, employing two types of data: vehicle trajectory data, and sensor data. This work also considers the extension of the ARZ and the GARZ models to models with a relaxation term, and conducts an investigation of the optimal relaxation time.

The measured cross section for the range 60 < m[l'l'] < 120 GeV is sigma(pp to WZ) = 39.9 +/- 3.2 (stat) +2.9/-3.1 (syst) +/- 0.4 (theo) +/- 1.3 (lumi) pb, consistent with the standard model prediction.

description: We demonstrate how meshfree finite difference methods can be applied to solve vector Poisson problems with electric boundary conditions. In these, the tangential velocity and the incompressibility of the vector field are prescribed at the boundary. Even on irregular domains with only convex corners, canonical nodal-based finite elements may converge to the wrong solution due to a version of the Babuska paradox. In turn, straightforward meshfree finite differences converge to the true solution, and even high-order accuracy can be achieved in a simple fashion. The methodology is then extended to a specific pressure Poisson equation reformulation of the Navier-Stokes equations that possesses the same type of boundary conditions. The resulting numerical approach is second order accurate and allows for a simple switching between an explicit and implicit treatment of the viscosity terms.

description: In this paper we present the perturbative evaluation of the difference between the renormalization functions of flavor singlet and nonsinglet bilinear quark operators on the lattice. The computation is performed to two loops and to lowest order in the lattice spacing, for a class of improved lattice actions, including Wilson, tree-level (TL) Symanzik and Iwasaki gluons, twisted mass and SLiNC Wilson fermions, as well as staggered fermions with twice stout-smeared links. In the staggered formalism, the stout smearing procedure is also applied to the definition of bilinear operators.

description: It is well known that most road construction projects in Ethiopia and Addis Ababa city are exposed to time and cost overrun or both. It becomes difficult to complete road projects in the allocated cost and time. Therefore, this research was carried out to dig-out information on the factors that cause time overrun on Asphalt road construction projects in Addis Ababa City administration. The aim of this research is to assess factors contributing for time overruns on road construction projects in Addis Ababa city Administration in the views of road construction stakeholders. Questionnaire survey was used to collect data on causes of time overrun. A total of 47 questionnaires from owner (AACRA), contractors and consultants were collected on the common factors to contribute for time overrun on asphalt road construction projects completed from 2000-2005E.c in Addis Ababa city administration by using a purposive sampling technique and analyzed using both descriptive and inferential statistics. Secondary data (asphalt road construction projects completion report) was used to know the real extent of time overrun on the projects understudied. From the result, it was found that 80% of the projects suffered time overrun. The most important causes of time overrun were found to be slow cite clearance, contractors' financial problems, Inflation, progress payments delay by owner, inaccurate cost estimation, and delay in commencement. Spearman rank order correlation analysis was used to evaluate whether consensus of views exists between groups of respondents (owner versus contractor, owner versus consultant and contractor versus consultant). From the analysis of the results, it was found that there is no consensus of opinion between owner versus contractor and owner versus consultant respondents on the factors that cause time overrun but there is consensus between contract and consultant respondents. Lack of adequate literatures' on my case study was the limitation of this study. Key words: time overrun, causes, factors, asphalt road construction projects, Road construction project stake holders.

description: I examine the hypothesis that consciousness can be understood as a state of matter, "perceptronium", with distinctive information processing abilities. I explore five basic principles that may distinguish conscious matter from other physical systems such as solids, liquids and gases: the information, integration, independence, dynamics and utility principles. This approach generalizes Giulio Tononi's integrated information framework for neural-network-based consciousness to arbitrary quantum systems, and provides interesting links to error-correcting codes and condensed matter criticality, as well as an interesting connections between the emergence of consciousness and the emergence of time.

description: Background: Neuroimaging studies have provided valuable insights into the macroscale impacts of antidepressants on brain functions in patients with major depressive disorder. However, the findings of individual studies are inconsistent. Here, we aimed to provide a quantitative synthesis of the literature to identify convergence of the reported findings at both regional and network levels and to examine their associations with neurotransmitter systems.Methods: Through a comprehensive search in PubMed and Scopus databases, we reviewed 5,258 abstracts and identified 37 eligible functional neuroimaging studies on antidepressant effects in major depressive disorder. Activation likelihood estimation was used to investigate regional convergence of the reported foci of consistent antidepressant effects, followed by functional decoding and connectivity mapping of the convergent clusters. Additionally, utilizing group-averaged data from the Human Connectome Project, we assessed convergent resting-state functional connectivity patterns of the reported foci. Next, we compared the convergent circuit with the circuits targeted by transcranial magnetic stimulation (TMS) therapy. Last, we studied the association of regional and network-level convergence maps with the selected neurotransmitter receptors/transporters maps.Results: We found regional convergence of the reported treatment-associated increases of functional measures in the left dorsolateral prefrontal cortex, which was associated with working memory and attention behavioral domains. No regional convergence was found across foci of alterations in functional imaging associated with antidepressants. Moreover, we found network-level convergence of functional alterations in a circuit that was prominent in the frontoparietal and salience networks. This circuit was co-aligned with a circuit targeted by anti-subgenual TMS therapy. We observed no significant correlations between our meta-analytic findings with the maps of neurotransmitter receptors/transporters.Conclusion: Our findings highlight the importance of the left dorsolateral prefrontal cortex, as well as frontoparietal network and the salience network in the therapeutic effects of anti-depressants, possibly associated with their role in improving executive functions and emotional processing.
Rotating Bose-Einstein condensates with a finite number of atoms confined in a ring potential: Spontaneous symmetry breaking, beyond the mean-field approximation

description: Motivated by recent experiments on Bose-Einstein condensed atoms which rotate in annular/toroidal traps we study the effect of the finiteness of the atom number $N$ on the states of lowest energy for a fixed expectation value of the angular momentum, under periodic boundary conditions. To attack this problem, we develop a general strategy, considering a linear superposition of the eigenstates of the many-body Hamiltonian, with amplitudes that we extract from the mean field approximation. This many-body state breaks the symmetry of the Hamiltonian, it has the same energy to leading order in $N$ as the mean-field state and the corresponding eigenstate of the Hamiltonian, however it has a lower energy to subleading order in $N$ and thus it is energetically favorable.

description: Das "Leitbild" des virtuellen Unternehmens, das für die räumliche, zeitliche und soziale Entgrenzung der Leistungserstellung in (globalen) Computernetzen wirbt, entwickelt sich zu einem weiteren Innovationsparadigma für Organisationen. An drei Fallbeispielen illustriert der Beitrag die "Wirkungen" des neuen Paradigmas auf neuentstehende und auf etablierte Unternehmen. Die Umsetzung dieses Leitbildes in der Unternehmenspraxis erfolgt deutlich vorsichtiger als erwartet. Die konventionellen Strukturen der betrieblichen Leistungserstellung lösen sich, soweit bisher erkennbar, nicht auf. Es ist zu vermuten, dass dem Diskurs um das Zukunftsmodell "virtuelles Unternehmen" eine Reihe "blinder Flecke" anhaftet, die eine erfolgreichere Multimediastrategie der Unternehmen behindert. Vor allem ein desozialisierter, auf den Begriff des Datenaustausches reduzierter Kommunikationsbegriff des Modells führt dazu, die Funktionen räumlicher, zeitlicher und sozialer Integration im Unternehmen systematisch zu verkennen.
description: The "vision" of the virtual company, which advertises for the spatial, temporal and social boundlessness of the service preparation in (global) computer networks, develops itself into a further innovation paradigm for organizations. The paper illustrates with three examples the effects of the new paradigm on new and on established corporations. The conversion of this vision into company practice occurs clearly more cautiously as expected. The conventional structures of the company service preparation do not remove themselves, as far as we can see. It is to be presumed that the discourse around the future model of "virtual company" adheres a line of blind spots, which hinder a more successful multimedia strategy of the companies. Above all a desocialized term of communication in the model, which reduces communication to data exchange, leads to misjudging systematically the functions of spatial, temporal and social integration in companies.

description: This study is concerned with assessing the institutional framework that can develop entrepreneurship with taking three sub cities of Addis Ababa namely Kolfe Keraniyo, Lideta and Gullele as a case. The study is geared towards answering key questions related to policies and strategies in place to facilitate and encourage entrepreneurial activities among Micro and Small enterprises, assistance provided by Woredas" SME development bureaus responsive to the needs of the enterprises, the linkage and coordination among Woredas" SME development bureaus and other government and non-government institutions involved in entrepreneurship development process and problems related to the Woredas" SMEs" development bureaus" institutional framework that entrepreneurs are operating under and has made endeavors on identifying the major problems of the current institutional environment. Data have been collected from 100 respondent enterprises and also interviews were conducted with FeMSEDA officials and the Woreda officials operating under the selected sub cities. The policies, strategies and procedures of entrepreneurship development in the country have been reviewed. Data analysis revealed significant differences in the needs of the entrepreneur and the encouragement of the Agency in the success of the enterprises. The study findings have revealed that though the strategy and procedures indeed encourage small firms, the institutional framework and way of implementation still need to be improved to promote entrepreneurship.
