Year: 2018

description: Facility location problems are long-term decision making problems for selection best geographical location to begin the operations of a new facility or for expansion of existing facilities. These are strategic investment decision including many factors that may be inconsistent in nature. To solve this problems, some alternatives based on different criteria’s need to be selected. To make a decision on such fuzzy problems, fuzzy multiple criteria decision making can be applied. In this paper, fuzzy multiple criteria decision making with TOPSIS and weighted product (WP) methods is used to select the best location of company facility. The results of solving represent that TOPSIS and Weighted Product fuzzy multiple criteria decision making methods can be used to select the most suitable place for new facility or for expansion of existing facilities.

description: We theoretically examine the effect of carrier-carrier scattering processes (electron-hole and electron-electron) on the intraband radiation absorption and their contribution to the net dynamic conductivity in optically or electrically pumped graphene. We demonstrate that the radiation absorption assisted by the carrier-carrier scattering can be stronger than the Drude absorption due to the carrier scattering on disorder. Since the intraband absorption of radiation effectively competes with its interband amplification, this can substantially affect the conditions of the negative dynamic conductivity in the pumped graphene and, hence, the interband terahertz and infrared lasing. We find the threshold values of the frequency and quasi-Fermi energy of nonequilibrium carriers corresponding to the onset of negative dynamic conductivity. The obtained results show that the effect of carrier-carrier scattering shifts the threshold frequency of the radiation amplification in pumped graphene to higher values. In particular, the negative dynamic conductivity is attainable at the frequencies above 6 THz in graphene on SiO2 substrates at room temperature. The threshold frequency can be decreased to markedly lower values in graphene structures with high-k substrates due to screening of the carrier-carrier scattering, particularly at lower temperatures.

description: Quasiparticles with Weyl dispersion can display an abundance of novel topological, thermodynamic and transport phenomena, which is why novel Weyl materials and platforms for Weyl physics are being intensively looked for in electronic, magnetic, photonic and acoustic systems. We demonstrate that conducting materials in magnetic fields generically host Weyl excitations due to the hybridisation of phonons with helicons, collective neutral modes of electrons interacting with electromagnetic waves propagating in the material. Such Weyl excitations are, in general, created by the interactions of helicons with longitudinal acoustic phonons. An additional type of Weyl excitation in polar crystals comes from the interaction between helicons and longitudinal optical phonons. Such excitations can be detected in X-ray and Raman scattering experiments. The existence of the Weyl excitations involving optical phonons in the bulk of the materials also leads to the formation of topologically protected surface arc states that can be detected via surface plasmon resonance.

description: Stable algorithms for the formation of control actions in local-optimal adaptive control systems for dynamic objects are given. Considering that the initial equations for estimating the parameters of an object and a control device, as a rule, are ill-conditioned, it becomes necessary to use regular methods. The stable algorithms for finding the desired solutions based on the methods of the minimum pseudoinverse matrix and singular decomposition, which contribute to improving the accuracy of the formation of control actions, are given.

description: We consider fully nonlinear obstacle-type problems of the form \begin{equation*} \begin{cases} F(D^{2}u,x)=f(x) & \text{a.e. in}B_{1}\capΩ,|D^{2}u|\le K & \text{a.e. in}B_{1}\backslashΩ, \end{cases} \end{equation*} where $Ω$ is an unknown open set and $K>0$. In particular, structural conditions on $F$ are presented which ensure that $W^{2,n}(B_1)$ solutions achieve the optimal $C^{1,1}(B_{1/2})$ regularity when $f$ is Hölder continuous. Moreover, if $f$ is positive on $\overline B_1$, Lipschitz continuous, and $\{u\neq 0\} \subset Ω$, then we obtain local $C^1$ regularity of the free boundary under a uniform thickness assumption on $\{u=0\}$. Lastly, we extend these results to the parabolic setting.

description: In healthy sleepers, cortical alpha oscillations are present during the transition from wakefulness to sleep, and dissipate at sleep onset. For individuals with insomnia, alpha power is elevated during the wake-sleep transition and can persist throughout the night. Neuromodulation techniques using phase-locked stimulation have been put forth as alternatives to drugs for improving slow-wave sleep quality. Due to technical limitations, this approach has not been tested on faster frequency alpha oscillations. Here we examine the feasibility of using an endpoint-corrected version of the Hilbert Transform (ecHT) algorithm implemented on-device to measure alpha phase and deliver phase-locked auditory stimulation to modulate alpha and promote sleep initiation. First, the ecHT algorithm is implemented on a tabletop electroencephalogram (EEG) device and used to measure the timing of the auditory evoked response and its delivery at precise phases of the alpha oscillation. Secondly, a pilot at-home study tests feasibility to use a wearable version of the neuromodulation device for real-time phase-locked stimulation in the alpha (8-12 Hz) frequency range. Auditory stimulation was delivered at the intended phases of alpha with high precision, and alpha oscillations were affected differently by stimuli delivered at opposing phases. Our wearable system was capable of measuring sleep micro- and macro-events present in the EEG that were appropriate for clinical sleep scoring. Sleep onset latencies were reduced for a subset of subjects displaying sleep onset insomnia symptoms in the stimulation condition. This study demonstrates the feasibility of closed-loop tracking and neuromodulation of alpha oscillations using a wearable EEG device. Preliminary results suggest that this approach could be used to accelerate sleep initiation in individuals with objective insomnia symptoms.

description: Bangladesh Bureau of Statistics (BBS) has vowed to convert Census/Surveys micro data for next generation technology format use processed in IBM proprietary technology. After Bangladesh’s independence, there is a rich repository of statistical information in IBM 360 to ES/9000 mainframe tapes, dating back to late 1970s and early 2000s time. The overarching objective is to strengthen the prevailing national statistical archiving system. BBS will be making available of this large volume of converted data to the citizens of Bangladesh (if needed world community) so that academic and scholarly debates can take place taking cognizance of historical data.

This is a big step towards dissemination of Big Data covering Bangladesh’s economic developmental trend since its birth in 1971. By revisiting time series data, it is hoped that well-informed and meticulous policies can be designed and formulated in the future. Most fundamentally, availability and easy accessibility to such a large volume of Data will inspire reassessing economic theories and indicators of development informing Bangladesh’s position in global rankings like SDG. BBS have their own data policy but no Metadata policy yet. In this Ice breaking situation DDI can play an excellent role to develop standard metadata and DDI4 will be implemented in BBS where 47 years of legacy data are available.

description: Using neutrinos produced at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL), the COHERENT collaboration has studied the Pb($ν_e$,X$n$) process with a lead neutrino-induced-neutron (NIN) detector. Data from this detector are fit jointly with previously collected COHERENT data on this process. A combined analysis of the two datasets yields a cross section that is $0.29^{+0.17}_{-0.16}$ times that predicted by the MARLEY event generator using experimentally-measured Gamow-Teller strength distributions, consistent with no NIN events at 1.8$σ$. This is the first inelastic neutrino-nucleus process COHERENT has studied, among several planned exploiting the high flux of low-energy neutrinos produced at the SNS.

description: We present a tomographic protocol for the characterization of multiqubit quantum channels. We discuss a specific class of input states, for which the set of Pauli measurements at the output of the channel directly relates to its Pauli transfer matrix components. We compare our results to those of standard quantum process tomography, showing an exponential reduction in the number of different experimental configurations required by a single matrix element extraction, while keeping the same number of shots. This paves the way for more efficient experimental implementations, whenever a selective knowledge of the Pauli transfer matrix is needed. We provide several examples and simulations.

Hexagonal warping on spin texture, Hall conductivity and circular dichroism of Topological Insulator

description: The topological protected electronic states on the surface of a topological insulator can progressively change their Fermi cross-section from circular to a snowflake shape as the chemical potential is increased above the Dirac point because of an hexagonal warping term in the Hamiltonian. Another effect of warping is to change the spin texture which exists when a finite gap is included by magnetic doping, although the in-plane spin component remains locked perpendicular to momentum. It also changes the orbital magnetic moment, the matrix element for optical absorption and the circular dichroism. We find that the Fermi surface average of z-component of spin is closely related to the value of the Berry phase. This holds even when the Hamiltonian includes a subdominant non-relativistic quadratic in momentum term (which provides particle-hole asymmetry) in addition to the dominant relativistic Dirac term. There is also a qualitative correlation between $\left\langle S_z \right\rangle$ and the dichroism. For the case when the chemical potential falls inside the gap between valence and conduction band, the Hall conductivity remains quantized and unaffected in value by the hexagonal warping term.

Not-so-big Data: Using DDI to Promote Findable, Re-usable Data Across Small N Studies in the Traumatic Stress Field
Creators: name: Kassam-Adams, Nancy
Publisher: name: Zenodo
Year: 2018

description: Beyond big data or longitudinal studies, DDI may be useful with the ‘long tail’ of smaller research studies, where data re-use can provide valuable insights beyond the original study findings. The traumatic stress field presents an exemplar use case - while studies yield rich and potentially re-usable data, datasets are not easily discoverable and few have metadata that readily enables harmonization and re-use. For child acute trauma (e.g., disaster, injury, violence), understanding risk and protective factors for traumatic stress and health outcomes requires prospective studies that follow children identified soon after the event. These resource-intensive studies generally enroll small samples (i.e., N’s of 50 to 500) and employ similar but non-identical measurement strategies; cross-study analyses of pooled and harmonized data can add great value. The Prospective studies of Acute Child Trauma and Recovery (PACT/R) Data Archive (www.childtraumadata.org) is an international collaborative effort to create a research resource for this field, with a searchable online portal and harmonization algorithms. PACT/R currently includes 26 datasets representing >3700 trauma-exposed children. This project report will (a) illustrate initial application of DDI metadata to the PACT/R Archive, and (b) describe progress and challenges in applying DDI to traumatic stress data to facilitate discoverability and harmonization.

description: Single-electron sources are an essential component of modern quantum nanoelectronic devices. Owing to their high accuracy and stability, they have been successfully employed for metrology applications, studying fundamental matter interactions and more recently for electron quantum optics. They are traditionally driven by state-of-the-art arbitrary waveform generators that are capable of producing single-electron pulses in the sub-100 ps timescale. In this work, we use an alternative approach for generating ultrashort electron wavepackets. By combining several harmonics provided by a frequency comb, we synthesise Lorentzian voltage pulses and then use them to generate electron wavepackets. Through this technique, we report on the generation and detection of an electron wavepacket with temporal duration of 27 ps generated on top of the Fermi sea of a 2-dimensional electron gas - the shortest reported to date. Electron pulses this short enable studies on elusive, ultrafast fundamental quantum dynamics in nanoelectronic systems and pave the way to implement flying electron qubits by means of Levitons.

Challenges of Using DDI in research data sharing in Uganda. A case of selected research institutions
Creators: name: Akullo, Winny Nekesa
Publisher: name: Zenodo
Year: 2018

description: Uganda has a number of institutions that carry out research both for decision making and evidence based planning. This data is described using various standards and is disseminated to various stakeholders. Some of these stakeholders who are researchers re-use the data for further analysis. The Data Documentation Initiative (DDI) on the other hand is an international standard for describing the data produced by surveys and other observational methods in the social, behavioral, economic, and health sciences. DDI is a free standard that can document and manage different stages in the research data lifecycle, such as conceptualization, collection, processing, distribution, discovery, and archiving. This paper shall examine the challenges the research institutions face when sharing research data. The objectives of the research are; to find out whether the research institutions use DDI for data sharing; to find out the challenges they face; and propose ways in which they can use DDI to improve data sharing.

description: In this paper, we will analyze the effects of $α^{\prime} $ corrections on the behavior of a Reissner-Nordström black hole. We will calculate the effects of such corrections on the thermodynamics and thermodynamic stability of such a black hole. We will also derived a novel $α^{\prime}$-corrected first law. We will investigate the effect of such corrections on the Parikh-Wilczek formalism. This will be done using cross entropy and Kullback-Leibler divergence between the original probability distribution and the $α^{\prime}$-corrected probability distribution. We will then analyze the non-equilibrium quantum thermodynamics of this black hole. It will be observed that its quantum thermodynamics is corrected due to quantum gravitational corrections. We will use Ramsey scheme for emitted particles to calculate the quantum work distribution for this system. The average quantum work will be related to the difference of $α^{\prime}$-corrected free energies using the Jarzynski equality.

We also give examples to show that not all upper cluster algebras are F-regular if the local acyclicity is dropped.

On the preservation of media trustworthiness in the social media era
Creators: name: Lago, Federica
Publisher: name: Universit� degli studi di Trento
Year: 2022

description: The amount of multimedia content shared everyday online recently underwent a dramatic increase. This, combined with the stunning realism of fake images that can be generated with AI-based technologies, undermines the trustworthiness of online information sources. In this work, we tackle the problem of preserving media trustworthiness online from two different points of view. The first one consists in assessing the human ability to spot fake images, focusing in particular on synthetic faces, which are extremely realistic and can represent a severe threat if used to disseminate fake news. A perception study allowed us to prove for the first time how people are more prone to question the reality of authentic pictures rather than the one of last-generation AI-generated images. Secondly, we focused on social media forensics: our goal is to reconstruct the history of an image shared or re-shared online as typically happens nowadays. We propose a new framework that is able to trace the history of an image over multiple sharings. This framework improves the state of the art and has the advantage of being easily extensible with new methods and thus adapt to new datasets and scenarios. In fact, in this environment of fast-paced technological evolution, being able to adapt is fundamental to preserve our trust in what we see.

We identify the three critical pressures, P1 that is the turn-on critical pressure of the h-cT phase transition and it coincides with the critical pressure for the sign change of Hall coefficient from positive to negative, a manifestation of the Fermi surface reconstruction, P2 that is the turn-off pressures of the h-cT phase transition, and P3 that is the critical pressure of the f-cT phase transition. By comparing the high-pressure results measured from the two kinds of samples, we find a distinct left-shift of the P1 for the doped sample, at the pressure of which its SVC state is fully suppressed, however the P2 and the P3 remain the same as that of the undoped one. Our results not only provide a consistent understanding on the results reported before, but also demonstrate the importance of the Fe-As bonding in stabilizing the superconductivity of the iron pnictide superconductors through the pressure window.
ElasticSearch Index for DDI 3.2 Studies and Variables. Explore-Data project

Publisher: name: Zenodo
Year: 2018

description: DDI 3.2 presents a solid meta-data model to encode social sciences surveys meta-data, such as studies and variables. However, making this data accessible is another story. In Explore-Data project, our goal is to present a dynamic, multi-facets, and multilingual search portal for both studies and variables. Accordingly, we transform the content of DDI, available via DDI-FlatDB, into ElasticSearch index.

We consider two main document types in our index, namely study and variable. Each document type consists of a set of fields in order to keep as much of study/variable structure as possible. To support the multilingual content, we build many copies of each field for each language.

During the indexing process, we were obliged to deal with migration of data, missing values, remove duplicated and redundant data, and sometimes to generate new data. Index content can be queried via classical Google-style queries. However, the same content can be also browsed via many pre-defined facets in an e-Commerce websites style. Both ways can be used simultaneously in order to give to users a tool to dynamically access data and filter result list.

We have indexed about 6000 studies, distributed on 13 study collections such as ALLBUS, European Values Study, etc. In addition we currently index about 150K variables. In our presentation we introduce the Explore Data project at GESIS and describe indexing challenges to transform DDI Lifecycle 3.2 to ElasticSearch on study and variable level.

description: Interdependent networks have been shown to be extremely vulnerable based on the percolation model. Parshani et. al further indicated that the more inter-similar networks are, the more robust they are to random failure. Our understanding of how coupling patterns shape and impact the cascading failures of loads in interdependent networks is limited, but is essential for the design and optimization of the real-world interdependent networked systems. This question, however, is largely unexplored. In this paper, we address this question by investigating the robustness of interdependent ER random graphs and BA scale-free networks under both random failure and intentional attack. It is found that interdependent ER random graphs are robust-yet-fragile under both random failures and intentional attack. Interdependent BA scale-free networks, however, are only robust-yet-fragile under random failure but fragile under intentional attack. These results advance our understanding of the robustness of interdependent networks significantly.

description: In this paper several issues related to the development of industrial multi-agent systems within scope of managing complex technological processes and production with taking into account: the variety of solution methods; the availability of variety of information subject to incomplete and dispersed nature of technological processes, uncertainty in models and wide range of time frames for various system tasks and production situations are considered. To show that or the full disclosure of the potential of multi-agent systems reconfigurable production systems with performance adaptation are in demand. The tasks of developing an agent architecture, its functional organization and creating an agent community in distributed computing environments are considered, when the effective organization of interacting entities leads to problem solutions of cooperation, coordination and self-organization, and due actions of agents stimulate the execution of necessary processes.
Metadata Sharing. Rights and Obligations
Creators: name: Johnson, Jon
Publisher: name: Zenodo
Year: 2018

description: As metadata and data converge, particularly where evolving standards such as DDI4 can simultaneously be the data, the code that generated it and its metadata; it is apposite to revisit questions of intellectual copyright, licencing and sharing in a way that a metadata in the form of catalogue record has hitherto not.

Developing and maintaining such granularity of metadata can be an expensive proposition. There are costs associated with editing and publishing data and metadata.

Whist most institutions have a data policy, very few have a metadata policy and those that do, seem to be aligning on a policy that advocates or requires a Creative Commons Zero (CC0) licence. The perceived advantages of having such a policy are that it provides a clear and easy-to-understand guidance for users especially where metadata is shared across borders.

There are obligations which could reasonably be requested of those to whom metadata is shared. If it is being re-shared, is it up-to-date with the original source, has it been altered and is that transparent to a user, have derived products attributed the original source?

This session will seek to identify the main challenges that a step change in the nature of metadata means for providers and recipients of shared metadata and the subsequent technical challenges this may engender.

description: Quality performance in construction is the degree of compliance with the specifications against which the work was executed. Green buildings extend the compliance to sustainability-related aspects to ensure that the energy and water consumption is conserved, promote a healthy indoor environmental quality and reducing the detrimental impacts of the construction activities on the environment. The operational stage reflects the construction workmanship and the effectiveness of the design solution to achieve the sustainability requirements through the overall building performance. Procedures for maintenance and overhauling extend the longevity of buildings. Green buildings exhibit underperformance caused by inadequate construction practices and a lack of understanding of the operations and maintenance practices. This research serves to tackle this problem through a comprehensive and forward-looking framework to depict construction- and operation-related quality activities through an integrated definition for the function modeling (IDEF0) process model. Semi-structured interviews and a focus group validate the framework’s suitability and its implementation offered revelations from industry practitioners on the factors affecting quality procedures from assigned metrics, liaison of staff from different project lifecycle stages, green building technologies, commissioning and retro-commissioning and impact of project delivery systems adopted especially in isolating operational liaison. The contributions of this work reinforce the impact of quality on the sustainability objectives that a green building is envisioned to serve, and through capturing the pre-, during, and post-construction lifecycle, the compliance and performance quality aspects are combined in a more integrated manner.

description: In this work we present a refractive index sensor based on the leaky radiation of a microfiber. The 5.3um diameter microfiber is fabricated by drawing a commercial optical fiber. When the microfiber is immersed into a liquid with larger refractive index than the effective index of fiber mode, the light will leak out through the leaky radiation process. The variation of refractive index of liquid can be monitored by measuring radiation angle of light. The refractive index sensitivity can be over 400 degree/RIU in theory. In the experiment, the variation value 0.001 of refractive index of liquid around this microfiber can be detected through this technique. This work provides a simple and sensitive method for refractive index sensing application.

description: We solve and test experimentally a global-games model of speculative attacks where agents can choose whether to read, at a cost, a payoff irrelevant (sunspot) announcement. Assuming that subjects exogenously believe some others to follow sunspots, we provide conditions for a unique equilibrium where agents follow a sunspot announcement depending on the realization of an informative private signal. Although most groups converge to classical global-game strategies that neglect sunspots, we find that about one-third of groups are eventually coordinating on sunspots, which is inconsistent with the standard theory. In line with the assumption of subjects expecting others to follow sunspots, subjects overestimate the number of subjects who follow sunspots by about 100% on average. We conclude that in environments with high strategic uncertainty, payoff irrelevant signals can affect behavior even if they are costly to obtain and not expected to be publicly observed.

Origins of Valley Current Reversal in Partially Overlapped Graphene Layers

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Using the tight-binding model, we investigate the valley current of the `low-bi-up' and `low-bi-low' graphene junction, where `low' and `up' are respectively the lower and upper graphene layers extended from the central AB stacking bilayer graphene layer, `bi'. Source and drain electrodes connect with the left and right monolayer regions, respectively, and thus the total current is forced to flow through the interlayer path in the low-bi-up junction. We measure valley current reversal (VCR) using the average of $\frac{1}{2} \sum_{ν=\pm}(T_{ν,-ν}-T_{ν,ν})$ per lateral wave number, where $T_{ν,ν'}$ denotes the electron transmission rate from the left $K_{ν'}$ valley to the right $K_ν$ valley. Without the vertical electric field, the VCR is less than half in both junctions. This VCR is attributed to monolayer--bilayer matching. As the vertical field intensifies, the VCR declines in the low-bi-low junction, but increases to about 0.8 in the low-bi-up junction. This VCR enhancement originates from interlayer matching. Analytic scattering matrixes elucidate these matching effects. Experiments of VCR detection are also proposed.

description: The article analyzes the corporate network quality assessment. In the work questions of an estimation of qualitative indicators of corporate information-computed networks on the basis of neural networks are given. The main indicators are: information delay and packet loss. To evaluate the quality of the network, the use of a fuzzy model is proposed. A modeling algorithm for assessing the quality of a corporate information network is developed. The reliability of the proposed approach was verified with the help of a simulation system implemented with MatLab

description: We examine how conformal boundaries encode energy transport coefficients -- namely transmission and reflection probabilities -- of corresponding conformal interfaces in symmetric orbifold theories. These constitute a large class of irrational theories and are closely related to holographic setups. Our central goal is to compare such coefficients at the orbifold point (a field theory calculation) against their values when the orbifold is highly deformed (a gravity calculation) -- an approach akin to past AdS/CFT-guided comparisons of physical quantities at strong versus weak coupling. At the orbifold point, we find that the (weighted-average) transport coefficients are simply averages of coefficients in the underlying seed theory. We then focus on the symmetric orbifold of the $\mathbb{T}^4$ sigma model interface CFT dual to type IIB supergravity on the 3d Janus solution. We compare the holographic transmission coefficient, which was found by [1], to that of the orbifold point. We find that the profile of the transmission coefficient substantially increases with the coupling, in contrast to boundary entropy. We also present some related ideas about twisted-sector data encoded by boundary states.
description: 30 pages + references, 6 figures; v3: clarifying rewrites made to Section 2, including new discussion on twisted-sector boundary data, the role of extended symmetry currents, the relationship between the ICFT and BCFT pictures, and altered notation; new statements about transport at the orbifold point; some changes to presentation in abstract and Section 3; core results are unchanged
