description: We consider the D3-D7 model and use the spectral function of a probe fermion on D7 to analyze the first order phase transition from the black-hole embedding phase to another black-hole embedding phase in the presence of the finite density and temperature. From the fermionic spectral functions, we study the temperature dependence of the decay rate, and we observe various phenomena that support the first order phase transition including jump in it at the critical temperature that corresponds to the first order phase transition.

description: The $\textit{omg}$ protocol is a promising paradigm that uses multiple, application-specific qubit subspaces within the Hilbert space of each single atom during quantum information processing. A key assumption for $\textit{omg}$ operation is that a subspace can be accessed independently without deleterious effects on information stored in other subspaces. We find that intensity noise during laser-based quantum gates in one subspace can cause decoherence in other subspaces, potentially complicating $\textit{omg}$ operation. We show, however, that a magnetic-field-induced vector light shift can be used to eliminate this source of decoherence. As this technique requires simply choosing a certain, magnetic field dependent, polarization for the gate lasers it is straightforward to implement and potentially helpful for $\textit{omg}$ based quantum technology.

description: The federal sustainable development strategy (FSDS) for Canada advocated that public sector operations should aim at shrinking the environmental footprint while enhancing social benefits. In this quest, improving the sustainability performance of public buildings becomes a key constituent since buildings are responsible for the highest portion of the corporate GHG emission and energy usage of public entities. Moreover, public buildings are an important constituent of the socio-economic environment of a local region. Hence, there is a need for improving the sustainability performance of the future and existing public buildings. Currently, various innovative methods are used by federal, provincial and municipal entities to improve the sustainability performance of public buildings. However, asset management of building has been overlooked from the above studies. There is a lack of comprehensive methods to assess the level of service (LOS) of a building that is crucial for life cycle asset management. To address this problem, this paper proposes an approach to calculate the LOS of a recreational centre building operated by municipal government. Firstly, a LOS framework is formulated for recreational centre building by taking into consideration the key aspects. Secondly, a fuzzy synthetic evaluation method is used to assess the building performance. Thirdly, a case study was conducted to validate the proposed methodology. Results from this approach provide detailed information about the performance of the building assets. This approach facilitates in identifying areas that require immediate attention for improvement. This study provides a novel approach to life cycle asset management of public sector buildings.

description: Building and facility asset management is a strategic approach to the optimal capital and operational spending on assets to ensure control of cost and risk, asset life, performance, and stakeholder satisfaction. The decisions for sustainable building operations and infrastructure asset management ultimately rests on owners, stakeholders and building occupants. This paper introduces SocioBIM, an approach for building occupants to interact with their building and to provide valuable feedback to the building management. Our research takes advantage of the state-of-the-art and the-state-of-practice Building Information Modeling (BIM) technologies, sustainability assessment techniques, advanced analytics, decision support systems, and integrator platforms. The valuable insight derived from SocioBIM can solve important issues related to model-reality performance gaps, post-occupancy evaluation, sustainability and service level assessment, sustainable building operations and facility asset management. Furthermore, SocioBIM adds value and provides improved competitive advantage to any asset management organization.

description: Assuming a slow-roll inflationary model where conformal invariance of the Maxwell action is broken via a non-minimal kinetic coupling term, we investigate the non-Gaussian three-point cross-correlation function between the primordial curvature perturbation and the primordial magnetic field, under a fairly general choice of initial vacua for both the scalar and the gauge field sectors. Among the possible triangular configurations of the resulting cross-bispectrum, we find that the squeezed limit leads to local-type non-Gaussianity allowing a product form decomposition in terms of the scalar and magnetic power spectra, which is a generic result independent of any specific choice of the initial states. We subsequently explore its detection prospects in the CMB via correlations between pre-recombination $μ$-type spectral distortions and temperature anisotropies, sourced by such a primordial cross-correlation. Our analysis with several proposed next-generation CMB missions forecasts a low value of the signal-to-noise ratio (SNR) for the $μT$ spectrum if both the vacua are assumed to be pure Bunch-Davies. On the contrary, the SNR may be enhanced significantly for non-Bunch-Davies initial states for the magnetic sector within allowed bounds from current CMB data.

description: We revisit the one-dimensional model of the symmetric simple exclusion process slowly coupled with two unequal reservoirs at the boundaries. In its non-equilibrium stationary state, the large deviations functions of density and current have been recently derived using exact microscopic analysis by Derrida, Hirschberg and Sadhu in J. Stat. Phys. 182, 15 (2021). We present an independent derivation using the hydrodynamic approach of the macroscopic fluctuation theory (MFT). The slow coupling introduces additional boundary terms in the MFT-action, which modifies the spatial boundary conditions for the associated variational problem. For the density large deviations, we explicitly solve the corresponding Euler-Lagrange equations using a simple local transformation of the optimal fields. For the current large deviations, our solution is obtained using the additivity principle. In addition to recovering the expression of the large deviations functions, our solution describes the most probable path for these rare fluctuations.

description: We devise a new realization of the surface code on a rectangular lattice of qubits utilizing single-qubit and nearest-neighbor two-qubit Pauli measurements and three auxiliary qubits per plaquette. This realization gains substantial advantages over prior pairwise measurement-based realizations of the surface code. It has a short operation period of 4 steps and our performance analysis for a standard circuit noise model yields a high fault-tolerance threshold of approximately $0.66\% $. The syndrome extraction circuits avoid bidirectional hook errors, so we can achieve full code distance by choosing appropriate boundary conditions. We also construct variants of the syndrome extraction circuits that entirely prevent hook errors, at the cost of larger circuit depth. This achieves full distance regardless of boundary conditions, with only a modest decrease in the threshold. Furthermore, we propose an efficient strategy for dealing with dead components (qubits and measurements) in our surface code realization, which can be adopted more generally for other surface code realizations. This new surface code realization is highly optimized for Majorana-based hardware, accounting for constraints imposed by layouts and the implementation of measurements, making it competitive with the recently proposed Floquet codes.

Application of FAHP and Shannon Entropy in evaluating criteria significance in pipeline deterioration

Publisher: name: The University of British Columbia

description: Water Distribution Networks (WDNs) are the most important element in water supply systems. According to the Canadian Water and Wastewater Association (CWWA), there are more than 112,000 kilometers of water mains in Canada and their replacement cost is estimated to be $34 billion. Another $12 billion is required to service the projected growth. It is important to assess the long-term condition of WDNs to find their respective rate of deterioration in order to prevent disastrous failures and/or sudden shutdowns. Due to the limited data about water mains, condition of pipeline should be estimated based on available data. Therefore, to predict the pipeline condition, importance of each factor should be known. This study aims to calculate the weight of importance of factors that affect deterioration of pipelines. For this purpose, Fuzzy Analytical Hierarchy Process (FAHP) and Entropy Shannon are employed to prioritize the selected factors and calculate their relative weights based on their individual importance. Results show that pipe installation, age and material are the most effective parameters in modeling deterioration. These weights will be used in condition rating models to find the condition of pipelines based on their pipe characteristics, soil and water properties in order to estimate deterioration rate and expected remaining useful life.

description: Let $π_n$ be a uniformly chosen random permutation on $[n]$. Using an analysis of the probability that two overlapping consecutive $k$-permutations are order isomorphic, the authors of a recent paper showed that the expected number of distinct consecutive patterns of all lengths $k\in\{1,2,\ldots,n\}$ in $π_n$ is $\frac{n^2}{2}(1-o(1))$ as $n\to\infty$. This exhibited the fact that random permutations pack consecutive patterns near-perfectly. We use entirely different methods, namely the Stein-Chen method of Poisson approximation, to reprove and slightly improve their result.

description: A thermal interpretation of the stochastic formalism of a slow-rolling scalar field in de Sitter (dS) is given. We construct a correspondence between Hubble patches of dS and particles living in another space called an abstract space. By assuming a dual description of scalar fields and classical mechanics in the abstract space, we show that the stochastic evolution of the infrared part of the field is equivalent to the Brownian motion in the abstract space filled with a heat bath of massless particles. The 1st slow-roll condition and the Hubble expansion are also reinterpreted in the abstract space as the speed of light and a transfer of conserved energy, respectively. Inspired by this, we sketch quantum emergent particles, which may realize the Hubble expansion by an exponential particle production. This gives another meaning of dS entropy as entropy per Hubble volume.

Optimizing earthwork hauling plan with minimum cost flow network

Year: 2015

description: Linear programming is commonly used in earthwork hauling plan. However special expertise in forming and solving linear equations, along with considerable efforts in interpreting results, is required to apply these methods in practice. Moreover, previous methods mainly focus on cost estimation and thus largely ignore the constructability issues; this makes earthwork hauling plan impractical for construction planning. We aim to address these problems by introducing an intuitive graph based approach which optimizes the earthwork hauling plan using the minimum cost flow network. We choose the total traveling time as the objective function to be minimized in order to separate the earthwork hauling plan from other factors such as fleet combination. Our method directly connects adjacent sections allowing accessibility between them, instead of connecting the centers of cut and fill cells as potential haul routes as in previous methods. As a result, the proposed method is capable to handle constructability issues caused by “soft blocks” -which cannot be eliminated in establishing the standard flow network as their existence impose constraints on the grading plan. The graphic earth flow network can be used to guide the execution of the earthwork project and generate multiple grading plans, providing more flexibility compared to traditional methods. We present an earthmoving example with a reserved soft area and show that the proposed method is graphically intuitive, easy to establish and able to handle soft blocks.

description: Microservices are a way of splitting the logic of an application into small blocks that can be run on different computing units and used by other applications. It has been successful for cloud applications and is now increasingly used for edge applications. This new architecture brings many benefits but it makes deciding where a given service request should be executed (i.e. its placement) more complex as every small block needed for the request has to be placed.
 In this paper, we investigate energy-centric request placement for services that use the microservice architecture, and specifically whether using different energy metrics for optimization leads to different placement strategies. We consider the problem as an instance of a traveling purchaser problem and propose an integer linear programming formulation. This formulation aims at minimizing energy consumption while respecting latency requirements. We consider two different energy consumption metrics, namely overall or marginal energy, when applied as a measure to determine a placement.
 Our simulations show that using different energy metrics indeed results in different request placements. The paper presents several parameters influencing the extent of this difference.

description: This paper presents the utilization of advanced methodologies in aerial manipulation to address meaningful industrial applications and develop versatile ultrasonic Non-Destructive Testing (NDT) technologies with aerial robots. The primary objectives of this work are to enable multi-point measurements through sliding without re-approaching the work surface, and facilitate the representation of material thickness with B and C scans via dynamic scanning in arbitrary directions (i.e. omnidirections). To accomplish these objectives, a payload that can slide in omnidirections (here we call the omni-sliding payload) is designed for an over-actuated aerial vehicle, ensuring truly omnidirectional sliding mobility while exerting consistent forces in contact with a flat work surface. The omni-sliding payload is equipped with an omniwheel-based active end-effector and an Electro Magnetic Acoustic Transducer (EMAT). Furthermore, to ensure successful development of the designed payload and integration with the aerial vehicle, a comprehensive studying on contact conditions and system dynamics during active sliding is presented, and the derived system constraints are later used as guidelines for the hardware development and control setting. The proposed methods are validated through experiments, encompassing both the wall-sliding task and dynamic scanning for Ultrasonic Testing (UT), employing the aerial platform - Voliro T.

description: Σε αυτή την εργασία εξετάζεται από πολλές σκοπιές η επενδυτική φιλοσοφία ESG (Εnvironmental Social Governance). Μέσα από ιστορικές πηγές παρουσιάζεται η ίδρυση της φιλοσοφίας αυτής, η εξέλιξη της έως σήμερα και ποιος είναι ο τελικός σκοπός της, άρα και ο λόγος ύπαρξής της. Θα δούμε τα δομικά στοιχεία του ESG. Συγκεκριμένα το νομοθετικό και κανονιστικό πλαίσιο, στο οποίο μπορούν κατ’ αρχάς οι επενδύσεις αυτές να αποτελούν νόμιμη επιλογή από τους επενδυτές και διαχειριστές κεφαλαίων, αλλά και την υποχρέωση των εταιρειών στην εφαρμογή πολιτικών και δημοσίευση πληροφοριών ESG. Ως προς τα δομικά στοιχεία θα δούμε ακόμα μεθοδολογίες εταιρειών βαθμολογητών ESG καθώς και τα προβλήματα αυτών των μεθοδολογιών. Μέσω της επισκόπησης μιας πληθώρας ακαδημαϊκών εμπειρικών μελετών, θα διερευνήσουμε την σχέση κυρίως μεταξύ ESG επίδοσης, χρηματοοικονομικής απόδοσης και χρηματοοικονομικού ρίσκου. Ακόμα θα δούμε τον τρόπο που βλέπουν οι επενδυτές το ESG, δηλαδή τον ρόλο των θεσμικών επενδυτών, των ακτιβιστών επενδυτών, τον χρονικό ορίζοντα των επενδύσεων ESG, την δημοσιοποίηση πληροφοριών ESG, την επένδυση στην αποεπένδυση καθώς και το ESG σε σχέση με την κλιματική αλλαγή. Το ESG είναι εν μέρει εναντίον της φιλοσοφίας των παραδοσιακών επενδύσεων της ατομικότητας του κέρδους, αφού βασίζεται σε αρχές επενδυτικής ηθικής προς την κατεύθυνση της ευημερίας της κοινωνίας και του περιβάλλοντος.

description: We consider a system of $N$ spinless fermions, interacting with each other via a power-law interaction $ε/r^n$, and trapped in an external harmonic potential $V(r) = r^2/2$, in $d=1,2,3$ dimensions. For any $0 < n < d+2$, we obtain the ground-state energy $E_N$ of the system perturbatively in $ε$, $E_{N}=E_{N}^{\left(0\right)}+εE_{N}^{\left(1\right)}+O\left(ε^{2}\right)$. We calculate $E_{N}^{\left(1\right)}$ exactly, assuming that $N$ is such that the "outer shell" is filled. For the case of $n=1$ (corresponding to a Coulomb interaction for $d=3$), we extract the $N \gg 1$ behavior of $E_{N}^{\left(1\right)}$, focusing on the corrections to the exchange term with respect to the leading-order term that is predicted from the local density approximation applied to the Thomas-Fermi approximate density distribution. The leading correction contains a logarithmic divergence, and is of particular importance in the context of density functional theory. We also study the effect of the interactions on the fermions' spatial density. Finally, we find that our result for $E_{N}^{\left(1\right)}$ significantly simplifies in the case where $n$ is even.

Community Land Trust: de juridische sleutel tot betaalbaar wonen?
Creators: name: Marchau, Julie
Publisher: name: Zenodo

description: (English description below) 

De Community Land Trust (CLT) wordt in de rechtsleer als een mogelijke oplossing voor de wooncrisis beschouwd. Bij een CLT wordt de eigendom van de woning afgesplitst van de eigendom van de grond. Doordat de koper enkel de kostprijs van de woning draagt, is dit goedkoper. Wanneer de koper later besluit de woning door te verkopen, kan dit enkel met een beperkte winst, waarbij een deel daarvan terugvloeit naar de CLT. Op deze manier wordt de betaalbaarheid van de woning op lange termijn gewaarborgd.

Er bestaat geen uniforme manier om een CLT vorm te geven. Er zijn diverse juridische bouwstenen die kunnen worden ingezet om het beoogde doel te bereiken.

Dit onderzoek wil de huidige knelpunten bij de juridische vormgeving van CLT-projecten identificeren en wil evalueren of deze binnen het bestaande Belgische juridische kader kunnen worden opgelost. Hierbij hanteert het onderzoek een globale benadering over verschillende rechtsdomeinen heen.

The Community Land Trust (CLT) is considered in legal doctrine as a potential solution to the housing crisis. In a CLT, ownership of the home is separated from ownership of the land. Since the buyer only covers the cost of the home, this approach is more affordable. When the buyer later decides to sell the home, this can only be done with limited profit, part of which returns to the CLT. In this way, housing affordability is ensured in the long term.

There is no uniform way to structure a CLT. Various legal building blocks can be used to achieve the intended goal. 

This research aims to identify current challenges in the legal structuring of CLT projects and to evaluate whether these can be addressed within the existing Belgian legal framework. The research adopts a comprehensive approach that spans multiple areas of law.
Research for generating 2D-drawings of superstructure in highway bridge

description: Maintenance of highway bridges built during the high economic growth period is performed based on their design drawings and as-built drawings. For these elevated highway bridges, however, drawings were produced on paper media at the times of design and completion; therefore, in many cases they have already been disposed, making it difficult to perform maintenance. In such a case, regenerating the detail design of the current status is required, but it takes huge cost. For this problem, a large number of researches have been made on automatic generation of three-dimensional models for maintenance of highway bridges from point cloud data obtained through MMS (Mobile Mapping System). However, it is hard to use the models generated in these researches because engineers do not consider the original geometric information of highways. Thus in this research, we aim to regenerate the CAD drawings of the superstructure of an elevated highway bridge, and propose a method for extracting alignment information of the elevated highway bridge from point cloud data of MMS. We verify the usability of our method and system by comparing the experimental data with surveyed drawings in our experiments.

Sensor-based factorial experimental study on low back disorder risk factors among roofers

description: Roofers have long suffered from low back disorders (LBDs), which is a primary non-fatal injury in construction. Until present, most of the research on roofing safety is mainly focused on fatal injury risks such as falls from height, leaving much to be desired in the risk assessment of non-fatal, cumulative musculoskeletal disorders among roofers. Ergonomics studies have identified several physical risk factors associated with LBDs in workplaces and applied selective ones to develop predictive models for general LBD risk assessments. However, these models cannot be used for roofing assessments in that they are designed for general tasks without considering different roofer working postures and the effect of working on uneven rooftops. To understand the relationship between the risk factors (i.e., slope angle, posture, facing direction, and working pace) and LBD incidence in roofing shingle installation, a factorial in-lab experiment is conducted with the aid of the Vicon camera system and Electromyography (EMG) sensors. The bending angles and muscle strengths in the low back, which are measured by the two sensor systems, are analyzed as facts that indicate the LBD risk. The proposed experiment finds out the risk factors with significant effect on the LBD injury and interaction between the studied factors. The findings may be used to study the detailed ergonomic safety guidelines for roofing contractors, which will be useful for eliminating LBD risk factors on the roofing sites.

description: Background: Research on men who have experienced childhood sexual assault (CSA) is limited. Many available studies compare male and female experiences, describe male experiences, or examine sexual behavior in adulthood. We will present data on functioning in legal, psychological and psychopathological, and social and occupational areas for African American men who experienced CSA.

Results: Data show that 11.5% of the current sample report sexual contact before age 13, 4.5% report sexual contact with physical force between 14 and 17 years of age, and 2.4% report sexual contact with physical force after the age of 17. CSA was associated with higher rates of adult SA (p
Conclusion: These findings suggest that CSA increases individual risk for adverse psychological consequences and highlights the need to raise awareness and provide treatment for this specific population.
