description: At a time when tourism and culture are strongly affected by the growth of information online, the valorization of architectural sites - classified as protected areas - arises more than ever. How should architectural heritage be valued as a "tourist product" while respecting its preservation and authenticity?

Through the prism of public and territorial communications, we will concentrate on the valorization of the site of the ksar of Temacine, located at the edge of Oued Righ in the low Algerian Sahara. As a first step, it will be a question of analyzing the various supports and the various communication actions carried out by the institutional and associative actors aiming at the preservation and the promotion of this heritage site. In a second step, two aspects of the objectives of the communication on the authenticity of the heritage will be addressed: the creation of meaning and the economic valuation. Finally, in the third step, we will advocate a communication strategy combining the notion of heritage and cultural heritage tourism.

description: We use state-of-the-art molecular dynamics simulations to study hydrodynamic effects on aging during kinetics of phase separation in a fluid mixture. The domain growth law shows a crossover from a diffusive regime to a viscous hydrodynamic regime. There is a corresponding crossover in the autocorrelation function from a power-law behavior to an exponential decay. While the former is consistent with theories for diffusive domain growth, the latter results as a consequence of faster advective transport in fluids for which an analytical justification has been provided.

description: Electric vehicles (EVs) have become a popular mode of transportation, with their performance depending on the ageing of the Li-ion batteries used to power them. However, it can be challenging and time-consuming to determine the capacity retention of a battery in service. A rapid and reliable testing method for state of health (SoH) determination is desired. Ultrasonic testing techniques are promising due to their efficient, portable, and non-destructive features. In this study, we demonstrate that ultrasonic speed decreases with the degradation of the capacity of an LFP prismatic cell. We explain this correlation through numerical simulation, which describes wave propagation in porous media. We propose that the reduction of binder stiffness can be a primary cause of the change in ultrasonic speed during battery ageing. This work brings new insights into ultrasonic SoH estimation techniques.

description: The Kentucky Transportation Cabinet (KYTC) initiated the study KYSPR 17-532, “Deterioration Modelling of Bridges on BrM 5.2.3,” so it could receive assistance identifying and employing bridge deterioration and cost forecast modeling for its bridge maintenance program. The Kentucky Transportation Center (KTC) was to help coordinate KYTC in adapting BrM 5.2.3’s deterioration and cost modelling features and update the existing guide material to reflect all changes for BrM 5.2.3. This study included acquiring access and becoming familiar with AASHTO Bridge Management (BrM 5.2.3) software. It was also to explore opportunities for any training on BrM and BrM 5.2.3’s deterioration and cost modeling capabilities and adapt them to best meet KYTC’s maintenance needs for four National Bridge Elements (NBE) — Reinforced Concrete Deck (12), Steel Open Girder/Beam (107), Strip Seal Expansion Joint (300), and Moveable Bearing (311). But the lack sufficient and reliable data for element-level deterioration modelling has proved a hindrance and impeded the completion of the research. As data points are collected, deterioration rates should be checked occasionally to see if they require calibration.

description: This paper studies the predictability of metal futures returns. Additionally, we identify years of high predictability. Generally, we find a substantial degree of predictability both in- and out-of-sample. Gold returns seem to be best predictable out-of-sample. A timing strategy leads to utility gains of 2.18% p.a. In particular, the Aruoba–Diebold–Scotti (ADS) business conditions index incorporates relevant information for metal returns, and strongly predicts gold returns.

description: The Kentucky Transportation Cabinet (KYTC) has more aggressively pursued preventive maintenance in recent years. Sealing concrete bridge decks is one preventive maintenance activity the Cabinet has actively pursued. KYTC’s Divisions of Maintenance and Structural Design requested assistance from researchers at the Kentucky Transportation Center (KTC) in developing a material specification and application criteria for sealing concrete bridge decks at an appropriate time in their life cycle.

To develop a material specification and application criteria for sealing concrete bridge decks, KTC researchers conducted the following work:
1. Perform a national survey of departments of transportation (DOTs) for guidelines.
2. Perform a literature search to determine current practices and guidance.
3. Contact bridge deck sealer manufacturers for recommendations and review test methods.
4. Identify factors related to bridge decks that influence sealing.
5. Develop deck inspection criteria. 6.Prepare a final report that includes criteria for applying sealer to a bridge deck at the appropriate time and a material specification.

description: The generalized time-dependent generator coordinate method (TD-GCM) is extended to include pairing correlations. The correlated GCM nuclear wave function is expressed in terms of time-dependent generator states and weight functions. The particle-hole channel of the effective interaction is determined by a Hamiltonian derived from an energy density functional, while pairing is treated dynamically in the standard BCS approximation with time-dependent pairing tensor and single-particle occupation probabilities. With the inclusion of pairing correlations, various time-dependent phenomena in open-shell nuclei can be described more realistically. The model is applied to the description of saddle-to-scission dynamics of induced fission. The generalized TDGCM charge yields and total kinetic energy distribution for the fission of 240Pu, are compared to those obtained using the standard time-dependent density functional theory (TD-DFT) approach, and with available data.

description: Weingarten transformations which, by definition, preserve the asymptotic lines on smooth surfaces have been studied extensively in classical differential geometry and also play an important role in connection with the modern geometric theory of integrable systems. Their natural discrete analogues have been investigated in great detail in the area of (integrable) discrete differential geometry and can be traced back at least to the early 1950s. Here, we propose a canonical analogue of (discrete) Weingarten transformations for hyperbolic nets, that is, C^1-surfaces which constitute hybrids of smooth and discrete surfaces "parametrized" in terms of asymptotic coordinates. We prove the existence of Weingarten pairs and analyse their geometric and algebraic properties.

description: This study examines the willingness to pay (WTP) for the highland agriculture restriction policy which aims to stabilize the water quality in the Han River basin, South Korea. To estimate the WTP, we use a double-bounded contingent valuation method and a random-effects interval-data regression. We extend contingent valuation studies by dealing with the potential preference anomalies (shift, anchoring, and inconsistent response effects). The result indicates that after the preference anomalies are corrected, the statistical precision of parameter estimates is improved. After correcting the potential preference anomalies, estimated welfare gains are on average South Korean currency (KRW) 2,861 per month per household. Based on the WTP estimate, the total benefits from the land use restriction policy are around KRW 297.73 billion and the total costs are around KRW 129.44 billion. The net benefit is, thus, around KRW 168.29 billion. This study suggests several practical solutions that would be useful for the water management. First, a priority should be given to the valid compensation for the highland farmers’ expected income loss. Second, it is necessary to increase in the unit cost of the highland purchase. Third, wasted or inefficiently used costs (e.g., overinvestment in waste treatment facilities, and temporary upstream community support) should be transferred to the program associated with high mountainous agriculture field purchase. Results of our analysis support South Korean legislators and land use policy makers with useful information for the approval and operationalization of the policy.

description: KENTUCKY’S TRAFFIC COLLISION FACTS report is based on collision reports submitted to the Kentucky State Police Records Branch. As required by Kentucky Revised Statutes 189.635, “every law enforcement agency whose officers investigate a vehicle accident of which a report must be made...shall file a report of the accident...within ten days after investigation of the accident upon forms supplied by the bureau.” The stated purpose of this requirement is to utilize data on traffic collisions for such purposes as will improve the traffic safety program in the Commonwealth. Data contained in this report are based solely on the observations and judgements of the state and local police officers who investigated each collision. The collision data is contained in an automatic system (Collision Report Analysis for Safer Highways) (CRASH). This system has edit checks for accuracy. Computer tabulations and summaries are again checked for accuracy before information is released or disseminated. It is hoped that the detailed information presented in this report will, in fact, “improve the traffic safety program within the Commonwealth.”

description: Classical acoustoelasticity couples small-amplitude elastic wave propagation to an infinitesimal pre-deformation, in order to reveal and evaluate non-destructively third-order elasticity constants. Here, we see that acoustoelasticity can be also be used to determine fourth-order constants, simply by coupling a small-amplitude wave with a small-but-finite pre-deformation. We present results for compressible weakly nonlinear elasticity, we make a link with the historical results of Bridgman on the physics of high pressures, and we show how to determine "D", the so-called fourth-order elasticity constant of soft (incompressible, isotropic) solids by using infinitesimal waves.

description: Controlled dephasing of electrons, via 'which path' detection, involves, in general, coupling a coherent system to a current driven noise source. However, here, we present a case in which a nearly isolated electron puddle at thermal equilibrium strongly affects the coherence of a nearby electronic interferometer. Moreover, for certain average electron occupations of the puddle, the interferometer exhibits complete dephasing. This robust phenomenon stems from the Friedel Sum Rule, which relates a system's occupation with its scattering phases. The interferometer opens a peeping window into physics of the isolated electron puddle, which cannot be accessed otherwise.

description: This study investigates whether working time accounts affect the performance of German establishments based on the Establishment Panel from the Institute for Employment Research. The major results are: productivity and investments are positively correlated with working time accounts. No significant effects of working time accounts can be detected on wages and on operating surplus. On average, we find a tendency towards negative effects on profits. This result is less likely in phases of low product demand and for export-oriented, large establishments with a high share of skilled workers. Under strong sales fluctuations, we find positively significant effects on the operating surplus. JEL: C22, D21, J21, J22, J24

description: To the extent that students’ academic performance is affected by the composition of their classmates, peer effect is an important topic for social scientists, policymakers, and educators. If it does exist, it can provide opportunities for policy intervention in the optimal allocation of students and create avenues for enhancing social welfare. In this professional thesis, I study gender peer effects in China, specifically how the proportion of females in a classroom affects students’ overall academic performance. I will present evidence regarding the existence of such effects and investigate the underlying mechanisms. Discussion will follow on the non-linearity of such gender peer effects. It will be studied whether there will be more efficient distribution of students that will enhance overall students’ achievements. I will conduct a calibration to simulate gender peer effects in different scenarios and provide policy implications based on the magnitude and direction of such effects.
The Structure of Galaxies: II. Fitting Functions and Scaling Relations for Ellipticals

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: Surface photometry of 311 ellipticals from the 2MASS imaging database is analyzed with respect to the two most common fitting functions; the r^1/4 law and the Sersic r^1/n model. The advantages and disadvantages of each fitting function are examined. In particular, the r^1/4 law performs well in the middle regions, but is inadequate for the core (inner 5 kpcs) and the outer regions (beyond the half-light radius) which do not have r^1/4 shapes. It is found that the Sersic r^1/n model produce good fits to the core regions of ellipticals (r < r_half), but is an inadequate function for the entire profile of an elliptical from core to halo due to competing effects on the Sersic n index and the fact that the interior shape of an elliptical is only weakly correlated with its halo shape. In addition, there are a wide range of Sersic parameters that will equally describe the shape of the outer profile, degrading the Sersic models usefulness as a describer of the entire profile. Empirically determined parameters, such as half-light radius and total luminosity, have less scatter than fitting function variables. The scaling relations for ellipticals are often non-linear, but for ellipticals brighter than M_J < -23 the following structural relations are found: L propto r^0.8 \pm 0.1, L propto Sigma^-0.5 \pm 0.1 and Sigma propto r^-1.5 \pm 0.1.

Par quelles technologies et en fonction de quelles idéologies la médecine participe-t-elle à façonner des corps "bien" sexués ? Comment les pratiques médicales contribuent-elles à l'établissement et au renouvellement des normes de sexe et de sexualité ?

Les études réunies dans ce livre permettent de saisir les interrogations et les doutes de la médecine face aux transgressions de sexe et de sexualité. Peut-on convertir un homosexuel à l'hétérosexualité ? Identifier le sexe d'une personne ? Embellir les organes génitaux féminins ? Discipliner le corps des femmes enceintes ? Et comment les personnes résistent-elles à la normalisation médicale en matière de contraception, de disponibilité sexuelle ou de parcours de transition sexuelle ?

Ce livre permet de prendre la mesure des hésitations et des débats qui ont accompagné la constitution du savoir médical, avec une attention particulière à l'histoire suisse récente. Il met en lumière la labilité des frontières entre normalité et pathologique et permet de saisir tant les continuités que les changements d'appréhension du genre depuis le siècle dernier.

description: Aim: This study aimed to determine the attitude of Australian nursing lecturers to the use of technology applied to the teaching and learning of nursing students. Background: The use of technology in teaching was accelerated in reaction to the COVID-19 restrictions whereby measures, including social distancing and lockdowns, forced many higher education courses to transition online. Lecturers play a key role in the integration of technology in teaching, as it is the lecturer, not the technology, who facilitates the students’ learning experience. Design: A cross sectional survey design was used for this study, distributed from April to June of 2022. The purpose of the survey was to gather technology readiness data (via the TRI 2 questions) and descriptive data representative of the nursing academic population in Australia. Results: There was no statistically significant differences between participants based on demographic data (such as gender or age). There was an association between TRI 2 score and: the sum of elearning technologies engaged with; the frequency of engagement with technology and self-rated confidence with elearning. Of note were statistically significant differences of TRI between states/territories. Finally, there was an inverse relationship between the impact of COVID-19 restrictions and TRI 2 score. Conclusion: The study found that there was significant variation between states/territories and self-reported impact of TRI. Given that increased frequency and increased number of technologies engaged with are associated with technology readiness the variation between states/territories lockdowns which required engagement with technology, may have had an impact on the nursing academics attitude to technology. Importantly, this study found those who were highly technology ready found COVID-19 restrictions had less impact on them, suggesting that technology readiness may have assisted their transition to online learning.

description: The present work considers lamellar (micro) structures of thin, elastic lamellae embedded in a yielding matrix as a stability problem in the context of the theory of stability and uniqueness of path-dependent systems. The volume ratio of the stiff lamellae to the relatively soft matrix is assumed low enough to initiate a symmetric buckling mode, which is investigated by analytical and numerical means. Using a highly abstracted, incompatible model, a first approach is made, and the principal features of the problem are highlighted. Assuming plane strain deformation, an analytic expression for the bifurcation load of a refined, compatible model is derived for the special case of ideal plasticity and verified by numerical results. The effect of lamella spacing and matrix hardening on the bifurcation load is studied by a finite element unit cell model. Some of the findings for the ideal plastic matrix are shown to also apply for a mildly hardening matrix material. Furthermore, the postbuckling behaviour and the limit load are investigated by simulating a bulk lamella array.

description: The Taihu (Tai lake) region is one of the most economically prospering areas of China. Due to its location within this district of high anthropogenic activities, Taihu represents a drastic example of water pollution with nutrients (nitrogen, phosphate), organic contaminants and heavy metals. High nutrient levels combined with very shallow water create large eutrophication problems, threatening the drinking water supply of the surrounding cities. Within the international research project SIGN (SinoGerman Water Supply Network, www.water-sign.de), funded by the German Federal Ministry of Education and Research (BMBF), a powerful consortium of fifteen German partners is working on the overall aim of assuring good water quality from the source to the tap by taking the whole water cycle into account: The diverse research topics range from future proof strategies for urban catchment, innovative monitoring and early warning approaches for lake and drinking water, control and use of biological degradation processes, efficient water treatment technologies, adapted water distribution up to promoting sector policy by good governance. The implementation in China is warranted, since the leading Chinese research institutes as well as the most important local stakeholders, e.g. water suppliers, are involved. © 2016, The Author(s).
Equivalence of ELSV and Bouchard-Mariño conjectures for $r$-spin Hurwitz numbers

description: We propose two conjectures on Huwritz numbers with completed $(r+1)$-cycles, or, equivalently, on certain relative Gromov-Witten invariants of the projective line. The conjectures are analogs of the ELSV formula and of the Bouchard-Mariño conjecture for ordinary Hurwitz numbers. Our $r$-ELSV formula is an equality between a Hurwitz number and an integral over the space of $r$-spin structures, that is, the space of stable curves with an $r$th root of the canonical bundle. Our $r$-BM conjecture is the statement that $n$-point functions for Hurwitz numbers satisfy the topological recursion associated with the spectral curve $x = -y^r + \log y$ in the sense of Chekhov, Eynard, and Orantin. We show that the $r$-ELSV formula and the $r$-BM conjecture are equivalent to each other and provide some evidence for both.

description: We describe a new method for estimating the degree of "transientness" and "tonality" of a class of compound signals involving simultaneously transient and harmonic features. The key assumption is that both transient and tonal layers admit sparse expansions, respectively in wavelet and local cosine bases. The estimation is performed using particular form of entropy (or theoretical dimension) functions. We provide theoretical estimates on the behavior of the proposed estimators, as well as numerical simulations. Audio signal coding provides a natural field of application.
title: Small Sacral sites as both religious features and landscape networks in Central Europe
Creators: name: Brabec, Elizabeth
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: Though often overlooked due to their scale, networks of small sacral Christian architecture in the form of local churches, pilgrimage churches, chapels and small sacral sites, hold a significant importance in rural cultural landscapes in Europe and beyond. The networks are significant in their social stratification, diversity, distribution and abundance across cultural landscapes. The most significant development of networks of small sacral architecture in central and eastern Europe was during the Baroque under Catholicism, although the tradition builds on the marking of sacred sites during earlier periods of history throughout Europe.

A case study of the cultural landscapes of sacred sites in Bohemia, Czech Republic, illuminates the social layers that these sites produced, and identifies critical issues of documentation and challenges of interpretation of these networks. Sacred sites in Bohemia form three networks of cultural landscapes that are distinct from each other and only minimally connected: the sacred landscapes of the ruling class connecting family churches, crypts, shrines and hermitages; the networks of pilgrimage sites and routes; and the networks of small sacred sites, chapels and churches that dotted the agricultural landscape. These networks individually and collectively connected nature and culture in both intimate and large scale landscapes.

Small sacral sites are often accompanied by monumental single trees or a compositionally organised group of trees to create a sacred composition of nature and culture. They were important landmarks, indicators of place and landscape features of spatial organization for the residents of rural communities. At the other end of the range of scales, the monumental composed landscapes of the ruling class, covering upwards of 30 kilometers in length, connected religious sites (hermitages and pilgrimage chapels), family churches and crypts, and important natural sites, particularly natural water features.

This session elaborates on the origin, historical development and landscape values of small sacral Christian architecture, as well as their relation to separate natural features that create part of the sacral composition. The session explores the issues of documentation of these networks of sites, and the challenges that interpretation of connected sites over such large land areas creates.

description: To realize a dry sheet metal forming process, α-Fe 2 O 3 oxide layers were investigated regarding their friction characteristics, wear behavior and surface energy depending on different surface qualities of the specimens examined. The oxide layers were generated in a new hybrid batch furnace. The layer generation on all specimens of the tool steel 1.2379 used was performed at a target temperature below the annealing temperature (≈ 510 °C). Friction coefficients were examined with plane strip drawing tests. Wear experiments with oxidized wear specimens with variable surface topographies were carried out up to several thousand strokes per surface condition.

description: Regarding the Skyrme-Faddeev model on $\mathbb R^3$ as a $\mathbb C \mathbb P^1$ sigma model, we propose $\mathbb C \mathbb P^n$ sigma models on $\mathbb R^{2n+1}$ as generalisations which may support finite energy Hopfion solutions in these dimensions. The topological charge stabilising these field configurations is the Chern-Simons charge, namely the volume integral of the Chern-Simons density which has a local expression in terms of the composite connection and curvature of the CP^n field. It turns out that subject to the sigma model constraint, this density is a total divergence. We prove the existence of a topological lower bound on the energy, which, as in the Vakulenko-Kapitansky case in R^3, is a fractional power of the topological charge, depending on $n$. The numerical construction of the simplest ring shaped un-knot Hopfion on R^5 is also discussed.

Unveiling a network of parallel filaments in the Infrared Dark Cloud G14.225-0.506

description: We present the results of combined NH3(1,1) and (2,2) line emission observed with the Very Large Array and the Effelsberg 100m telescope of the Infrared Dark Cloud G14.225-0.506. The NH3 emission reveals a network of filaments constituting two hub-filament systems. Hubs are associated with gas of rotational temperature Trot \sim 25 K, non-thermal velocity dispersion ~1.1 km/s, and exhibit signs of star formation, while filaments appear to be more quiescent (Trot \sim 11 K, non-thermal velocity dispersion ~0.6 km/s). Filaments are parallel in projection and distributed mainly along two directions, at PA \sim 10 deg and 60 deg, and appear to be coherent in velocity. The averaged projected separation between adjacent filaments is between 0.5 pc and 1pc, and the mean width of filaments is 0.12 pc. Cores within filaments are separated by ~0.33 pc, which is consistent with the predicted fragmentation of an isothermal gas cylinder due to the 'sausage'-type instability. The network of parallel filaments observed in G14.225-0.506 is consistent with the gravitational instability of a thin gas layer threaded by magnetic fields. Overall, our data suggest that magnetic fields might play an important role in the alignment of filaments, and polarization measurements in the entire cloud would lend further support to this scenario.

description: We investigate whether vacuum solutions in flux compactifications that are obtained with smeared sources (orientifolds or D-branes) still survive when the sources are localised. This seems to rely on whether the solutions are BPS or not. First we consider two sets of BPS solutions that both relate to the GKP solution through T-dualities: (p + 1)-dimensional solutions from spacetime-filling Op-planes with a conformally Ricci-flat internal space, and p-dimensional solutions with Op-planes that wrap a 1-cycle inside an everywhere negatively curved twisted torus. The relation between the solution with smeared orientifolds and the localised version is worked out in detail. We then demonstrate that a class of non-BPS AdS(4) solutions that exist for IASD fluxes and with smeared D3-branes (or analogously for ISD fluxes with anti-D3-branes) does not survive the localisation of the (anti) D3-branes. This casts doubts on the stringy consistency of non-BPS solutions that are obtained in the limit of smeared sources.

description: We examine the use of high spatial resolution ‘GeoEYE’ imagery for land use classification in a tropical landscape. Image objects (I-Os) derived from features identification provide a basis for segmentation process and the Geographic Object Based Image Analysis (GEOBIA) framework. eCognition software with I-Os as classification unit and maximum likelihood algorithm facilitated the process. Supervised classification approaches (SCA) and rule set classification approach (RSCA) were used and performance and transferability of two approaches compared. Main conclusions: (a) high degree of details in GeoEYE data enables delineation of diverse land use zones, and (b) segmentation based analysis is more effective to tackle spatial intermixing. © 2016 by the authors.

On stress-dependent elastic moduli and wave speeds

description: On the basis of the general nonlinear theory of a hyperelastic material with initial stress, initially without consideration of the origin of the initial stress, we determine explicit expressions for the stress-dependent tensor of incremental elastic moduli. In considering three special cases of initial stress within the general framework, namely hydrostatic stress, uniaxial stress and planar shear stress, we then elucidate in general form the dependence of various elastic moduli on the initial stress. In each case the effect of initial stress on the wave speed of homogeneous plane waves is studied and it is shown how various special theories from the earlier literature fit within the general framework. We then consider the situation in which the initial stress is a pre-stress associated with a finite deformation and, in particular, we discuss the specialization to the second-order theory of elasticity and highlight connections between several classical approaches to the topic, again with special reference to the influence of higher-order terms on the speed of homogeneous plane waves. Some discrepancies arising in the earlier literature are noted.

description: Ultra-high-performance concrete (UHPC) sandwich structures with composite coating serve as multipurpose load-bearing elements. The UHPC’s extraordinary compressive strength is used in a multi-material construction element, while issues regarding the concrete’s brittle failure behaviour are properly addressed. A hollow section concrete core is covered by two steel tubes. The outer steel tube is wrapped in a composite material. By this design, UHPC is used in a material- and shape-optimised way with a low dead weight ratio[1] concerning the load-bearing capacity and stability[2]. The cross-section’s hollow shape optimises the construction’s buckling stability while saving self-weight. The composite coating on the column’s outside functions both as a layer increasing the construction’s durability and as a structural component increasing the the maximum and the residual load capacity. Investigations on the construction’s structural behaviour were performed.
