description: The American open-air museum was founded on the principles of identity, education, and preservation - objectives that have remained relevant to American society for over six decades, leading to the typology's longstanding history. While the use of the typology would be unheard of in today’s society, the movement has had a clear impact on the perception of America's built history and continues to do so today as these museums remain open for the public's enjoyment. While the bulk of the literature on the American open-air museum focuses on its Golden Age, in reality, the typology's development was far more encompassing, sweeping the entire nation in three distinct waves: the first in the 1930s and 40s with education tourism and the automobile, the second in the late 1950s and 60s in response to urban renewal and the threat of neglect, and the third in the late 1970s and 80s with a reinvestment in Americana in relation to the 1976 Bicentennial of the signing of the Declaration of Independence. This lack of research and discussion on the museum typology as a whole is the result of the negative connotation placed by preservation authorities on the typology's method of relocation. In order to claim the typology's long-deserved place within the historic preservation discourse, this thesis provides an overall context for the American open-air museum movement through the examination of three case studies as they relate to the three waves of museum creation: Old Sturbridge Village (1946), Nevada City, Montana (1959), and Old World Wisconsin (1976).

description: An area approximately 50m. south of the site of the medieval East Gate of Lewes (Fig. 1a) has been scheduled for redevelopment. Houghton's study of the property boundaries, and historic maps and drawings in relation to the standing buildings in this area, have led to the suggestion that the limit in building in the medieval period was west of the present line of Eastgate Street and Friar's Walk. To test this hypothesis, the Sussex Archaeological Field Unit carried out an excavation within the redevelopment area during June, 1976. It was planned to excavate a trench 30m. long and 3m. wide parallel to the line of the High Street. The only area of the site where this was possible proved to have a cellar occupying the eastern 9m. (Fig. 1b, trench A), and consequently an extra trench (Fig. 1b, trench B) was excavated 1.75m. north of the cellar, to complete the section. Standing buildings and buried services also complicated the layout of this excavation.

description: A common approach when setting up a website is to utilize third party Web hosting and content delivery networks. Without taking this trend into account, any measurement study inspecting the deployment and operation of websites can be heavily skewed. Unfortunately, the research community lacks generalizable tools that can be used to identify how and where a given website is hosted. Instead, a number of ad hoc techniques have emerged, e.g., using Autonomous System databases, domain prefixes for CNAME records. In this work we propose Pythia, a novel lightweight approach for identifying Web content hosted on third-party infrastructures, including both traditional Web hosts and content delivery networks. Our framework identifies the organization to which a given Web page belongs, and it detects which Web servers are self-hosted and which ones leverage third-party services to provide contents. To test our framework we run it on 40,000 URLs and evaluate its accuracy, both by comparing the results with similar services and with a manually validated groundtruth. Our tool achieves an accuracy of 90% and detects that under 11% of popular domains are self-hosted. We publicly release our tool to allow other researchers to reproduce our findings, and to apply it to their own studies.

description: We find a one-parameter family of variables which recast the 3+1 Einstein equations into first-order symmetric-hyperbolic form for any fixed choice of gauge. Hyperbolicity considerations lead us to a redefinition of the lapse in terms of an arbitrary factor times a power of the determinant of the 3-metric; under certain assumptions, the exponent can be chosen arbitrarily, but positive, with no implication of gauge-fixing.

description: This article is a faithful translation of Willy Wien's original publication from 1896: "Ueber die Energievertheilung im Emissionsspectrum eines schwarzen Körpers; von Willy Wien." where he states its distribution law that experiment does not confirm for long wavelength. He states that radiation intensity is inversely proportional to the fifth power of wavelength and a function of temperature and wavelength.

No translation found on the Internet respects the original form. We offer this translated version for students or amateurs wishing to understand or discover the origins of Planck's law and Quantum physics.
Simple non-perturbative resummation schemes beyond mean-field II: thermodynamics of scalar $ϕ^4$ theory in 1+1 dimensions at arbitrary coupling

description: Recently, non-perturbative approximate solutions were presented that go beyond the well-known mean-field resummation. In this work, these non-perturbative approximations are used to calculate finite temperature equilibrium properties for scalar $ϕ^4$ theory in two dimensions such as the pressure, entropy density and speed of sound. Unlike traditional approaches, it is found that results are well-behaved for arbitrary temperature/coupling strength, are independent of the choice of the renormalization scale $\barμ^2$, and are apparently converging as the resummation level is increased. Results also suggest the presence of a possible analytic cross-over from the high-temperature to the low-temperature regime based on the change in the thermal entropy density.

description: The phasor field has been shown to be a valuable tool for non-line-of-sight imaging. We present a formal analysis of phasor-field imaging using paraxial wave optics. Then, we derive a set of propagation primitives---using the two-frequency, spatial Wigner distribution---that extend the purview of phasor-field imaging. We use these primitives to analyze a set of simple imaging scenarios involving occluded and unoccluded geometries with modulated and unmodulated light. These scenarios demonstrate how to apply the primitives in practice and reveal what kind of insights can be expected from them.

description: The purpose of this study was to identify external factors affecting strategic management in agricultural knowledge and information system and to examine their relative importance from experts’ point of view. Five factors were identified based on the interviews, examination of relevant literature and previous researches; in line with that, a questionnaire was developed to suit this purpose. Face and content validity of the research instrument verified by the research committee. To determine the reliability of the instrument, a pilot study was conducted with 30 Agriculture-Jihad Organization personnel from Qazvin Province. The reliability coefficient (Cronbach’s alpha) was computed 0.95, which indicated that the questionnaire had a high reliability index. External factors consisted of sociocultural, policy, economic, technological, and ecological factors. The statistical population was consisted of line and staff experts of Agriculture Organizations of Alborz and Tehran Provinces (N=161). Data were analyzed by SPSSwin20 software. The results showed that sociocultural, economic, ecological, policy and technological factors were the most important external factors affecting strategic management in agricultural knowledge and information respectively.

description: The majority of disease-associated variants identified through genome-wide association studies are located outside of protein-coding regions. Prioritizing candidate regulatory variants and gene targets to identify potential biological mechanisms for further functional experiments can be challenging. To address this challenge, we developed FORGEdb (https://forgedb.cancer.gov/; https://forge2.altiusinstitute.org/files/forgedb.html; and https://doi.org/10.5281/zenodo.10067458), a standalone and web-based tool that integrates multiple datasets, delivering information on associated regulatory elements, transcription factor binding sites, and target genes for over 37 million variants. FORGEdb scores provide researchers with a quantitative assessment of the relative importance of each variant for targeted functional experiments.

description: This study is about music teaching strategies for students with low vision, including blindness. Based on a two-case ethnographic design, this study focuses on understanding what decisions in terms of activities, lesson plans, and curricula, six participants from two different schools adopted for their students, as well as how these decisions relate to these students’ special needs and the context of these two schools. One of these school was located in Santiago, Chile, while the other in New York, USA. Data collection included observations and fieldnotes, interviews and informal conversations, artifact and document collections, and the use of a reflective journal. Findings encompass a variety of strategies recorded in several formal learning spaces such as instrumental private lessons, music theory lessons, instrumental ensemble rehearsals, choir rehearsal, accessible music technology lessons, braille lessons, general music lessons. These strategies, in turn, seemed to be highly conditioned by the students’ special need as well as the social, political, economic, and cultural contexts of the two schools observed.

description: A prior report of the emergence of chirality for the (2x2x2) charge density wave (CDW) in TiSe2 has attracted much interest; the drastic symmetry breaking is highly unusual with few precedents [1]. In that study, key evidence was provided by x-ray diffraction measurements of two superlattice reflections, (1.5 1.5 0.5) and (2.5 1 0). The (2.5 1 0) reflection appeared to show an anomalously large intensity and a transition onset at ~7 K below that of the (1.5 1.5 0.5) reflection. These observations, aided by modeling, were cited as evidence for a separate chiral transition. In this Comment, we show that the prior conclusions based on x-ray diffraction are erroneous. There is just one transition, and it is achiral.

description: Due to concerns regarding potential environmental impacts of brine contamination in future, potash producers in Saskatchewan are required to submit decommission and reclamation plans for each of their mine sites to Saskatchewan Environment by July, 2005. While a number of technically feasible decommission, reclamation and related tailings management (DRTM) options exist, it is important to employ a credible and pragmatic method of evaluation in order to select the ‘best’ option from the standpoint of all stakeholders and thereby avoid potentially wasteful expenditure. For this reason, the authors worked with both industry and regulators to develop a generic, computer-based, cost-benefit modeling framework that supports a rational evaluation of considered DRTM options. Since both industry and regulators are committed to the modeling framework and related quantitative process, the modeling results and rankings reached will ultimately support the decommission and reclamation plans submitted by potash producers.
Propagation Failure in Excitable Media

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: We study a mechanism of pulse propagation failure in excitable media where stable traveling pulse solutions appear via a subcritical pitchfork bifurcation. The bifurcation plays a key role in that mechanism. Small perturbations, externally applied or from internal instabilities, may cause pulse propagation failure (wave breakup) provided the system is close enough to the bifurcation point. We derive relations showing how the pitchfork bifurcation is unfolded by weak curvature or advective field perturbations and use them to demonstrate wave breakup. We suggest that the recent observations of wave breakup in the Belousov-Zhabotinsky reaction induced either by an electric field or a transverse instability are manifestations of this mechanism.

Integration in the GHP formalism II: An operator approach for spacetimes with killing vectors, with applications to twisting type n spaces

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Held has proposed a coordinate- and gauge-free integration procedure within the GHP formalism built around four functionally independent zero-weighted scalars constructed from the spin coefficients and the Riemann tensor components. Unfortunately, a spacetime with Killing vectors will be unable to supply the full quota of four scalars of this type. However, for such a spacetime additional scalars are supplied by the components of the Killing vectors; by using these alongside the spin coefficients and the Riemann tensor components we have the possibility of constructing the full quota of four functionally independent zero-weighted scalars, and of exploiting Held's procedure. As an illustration we investigate the vacuum Type N spaces admitting a Killing vector and a homothetic Killing vector. In a direct manner, we reduce the problem to a pair of ordinary differential operator `master equations', making use of a new zero-weighted GHP operator. By first rewriting the master equations as a closed set of complex first order equations, we reduce the problem to one real third order operator differential equation for a complex function of a real variable --- but with still the freedom to choose explicitly our fourth coordinate. An alternative, more algorithmic approach, using a closed chain of real first order equations for real functions, reduces the problem to the same order, but in a more natural and much more concise form. It is also outlined how the various other third order differential equations, which have been derived previously by other workers on this problem, can be deduced from our master equations.

description: Frequent droughts and their consequences result in the loss of groundwater, the deficiency of nutrients, the drying of surface water resources, and substantially more exploitation of the groundwater resources, which, altogether, cause the mobilization of saline waters to groundwater tables. This will impair the capacity of the aquifers and the quality of the water. The VIKOR method was applied to determine the best feasible solution according to the selected criteria including the local rainfall status in different years, soil permeability, land slope, and water quality indicators, including SAR, RSC, salinity for determination of groundwater resources quality and land-use restrictions in the Kashmar Plain in the northeast of Iran. The results of sampling performed on the Kashmar Plain showed that water quality was lost as one moved from the northern groundwater tables to the southern ones. The excessive use of groundwater resources, the downfall of the groundwater level, and subsequently, the increased salinity account for the loss of the agricultural water quality and the land-use restrictions. Furthermore, the results of the model within years 2010 and 2014 showed that if the current form of indiscriminate exploitation of groundwater resources is kept, it will lead to the mobilization of the salinity to the lowly-saline upstream regions. Therefore, it is necessary to focus on sustainable management of groundwater resources, control their indiscriminate exploitation, and minimize the damage to the groundwater tables in the study site. In addition, agronomists should work on limiting the use of agricultural land by modifying the cropping pattern and on using deficitirrigation methods.

description: The purpose of this research was to analyze household food security and identifies key socio-economic factors associated with this condition among summer crop growers in Shoushtar Township, Khouzestan Province, Iran. This cross-sectional survey study was conducted from September 2015 to February 2017. The population consisted of summer crop farmers in the Shoushtar Township (N=850). The sample size was determined based on Morgan table (n=150). For analyzing food security level, the 18-item USDA household food security questionnaire, which contains questions that underlie the 12-month food security scale in survey-instrument form, was used. The food security scale was developed based on responses to questions Q2 to Q16 (18 questions). These include both qualitative and quantitative aspects of the household's food supply as well as household members' psychological and behavioral responses. Based on the results, more than half of households (52.67%) experienced food insecurity and less than half (47.33%) indicating that they are food secure. Correlation coefficient results showed that there was significant relationship between the income, educational level, extension education activities, social participation, technical knowledge and food security. Based on regression analysis, income, educational level, extension education activities, technical knowledge and social participation may well explain for 75.43% changes (R2=0.7543) in level of food security.

Conservatories of music

description: Music conservatories play an important role in the musical development of musicians. Students often choose to attend a conservatory because they are seeking to focus their efforts on honing their skills as performers, composers, or both. The use of music technology has increased in recent years as hardware and software has become more user friendly, resulting in the incorporation of music technology into the professional practice of musicians. While the innovation of technology has been swift, the adoption of music technology by educators in music conservatories has been slow when compared to those in other institutions of higher education. With each passing year, conservatories are graduating an increasing number of musicians who are met with greater expectations than those of previous generations. This multi-site case study investigated the perceived role of technology in the conservatory curriculum as reported by conservatory students and faculty. Further, this study examined the supports that are in place, for both students and faculty, in regard to integrating technology into current and future curricula. Research has been conducted to investigate the integration of technology into curricula; however, the research tends to focus on challenges for technology integration rather than technology as a tool for supporting sound pedagogical practice.
      Findings from this study indicate that students wish to see an increased presence of music technology in the curriculum as they hone their skills during their studies. Further, increased access to music technology, as well as support on using music technology in effective and engaging ways during instruction was identified. Conservatories can benefit from additional staff positions to support the use of music technology, frequent and relevant professional development for faculty, additional computer laboratories for student and faculty use, and increased communication between students, faculty and administration on the use of music technology throughout the conservatory. The implications of the findings and recommendations have the potential to positively impact the experience of students in conservatory communities. Future avenues of research might investigate the relevance of conservatory pedagogy in modern music performance and composition, pathways to support consistent and relevant professional development, and necessary supports to increase access to music technology for faculty and students.

description: The properties of the set L of extended jordanian twists are studied. It is shown that the boundaries of L contain twists whose characteristics differ considerably from those of internal points. The extension multipliers of these "peripheric" twists are factorizable. This leads to simplifications in the twisted algebra relations and helps to find the explicit form for coproducts. The peripheric twisted algebra U(sl(4)) is obtained to illustrate the construction. It is shown that the corresponding deformation U_{P}(sl(4)) cannot be connected with the Drinfeld--Jimbo one by a smooth limit procedure. All the carrier algebras for the extended and the peripheric extended twists are proved to be Frobenius.

description: Abench-scale updraft gasifier was used as a fluidizedand fixed-bed gasification unit in three modes (fluidizedbed at equivalence ratios (ER) =0.2 and 0.25, and a mode in fixed-bed). The experiments were done in five different temperatures (650, 700, 750, 800 and 850oC). To obtain the required data to develop a thermodynamic equilibrium model, the proximate and ultimate analysis were carried out on potato shoot as feedstock. Since the developed model is a temperature-based model, it gives different outcomes in different temperatures. The model gave a completely exact result to predict CH4 in fluidized-bed at ER=0.25. The average error for the difference between each produced gas in experiments and the model showed the best result of the model for CO with the error of just 0.7%. Regarding each experiment data difference with the model data, the model was more accurate to be used in fluidized-bed, especially at ER=0.25 than the other two modes. Moreover, the best performance of the model was obtained for CO, N2 and CO2, according to the average errors. Since the maximum amount of high heating value (HHV) and carbon conversion efficiency (CCE) was observed at higher temperatures, it can be contended that the model has better performance at higher temperatures.

Valves are also slightly smaller than those of the original A. proteus (length> 50 µm, width> 9 µm, Schoeman & Archibald 1986, Levkov 2009). However, the only valve we were able to find under SEM (fig. 8D) showed the presence of dimple-like depressions internally near the elongated central nodule, as in A. proteus (Levkov 2009, Pl. 248: 6). Another similar taxon in both dimensions and striation pattern, A. proteoides f. varians Proshkina-Lavrenko, was described from the Black Sea (Proshkina-Lavrenko 1963). Unfortunately, it is only known from her description and drawings (Proshkina-Lavrenko 1963, Pl. IX: 1–4), presenting insufficient details for species separation nowadays.

description: Nowadays, promoting entrepreneurship to train graduates endowed with entrepreneurial traits is considered as one of the new functions of the faculties of agriculture. In this regard, the purpose of this study was to design an appropriate model for entrepreneurial faculty of agriculture in Iran. This study was of descriptive-correlational research type in which a survey method was employed for data collect ion. The study po p ulation comprised all student s (N1=19973) and faculty members (N2=713) of all faculties of agriculture in Iran's state-run (public) universities of whom 403 students and 344 faculty members were sampled by multi-staged (three-stage) method. The sample size was determined by Krejcie and Morgan's sample size table. The research instrument was a self-designed questionnaire whose face and content validity were confirmed by a panel of experts. The diagnostic validity of the questionnaire in the case of its latent variables was also confirmed using the average variance extracted method (0.76≤AVE≤0.87). Furthermore, its internal consistency (0.81≤α≤0.93) and composite reliability (0.80≤Pc≤0.91) were confirmed using Cronbach's alpha coefficient. The collected data were also analyzed using SPSS22 and LISREL9.1. The results showed a significant relationship between structural, content, and contextual factors and entrepreneurship of faculties of agriculture. Meanwhile, content factors showed the greatest effect (path coefficient = 0.83) on the entrepreneurship of agricultural faculties. According to the findings, the final proposed model was developed with respect to the factors listed in three categories of education, research, and entrepreneurship for the establishment of entrepreneurial faculties of agriculture in Iran.

description: LiDAR-camera calibration is a precondition for many heterogeneous systems that fuse data from LiDAR and camera. However, the constraint from common field of view and the requirement for strict time synchronization make the calibration a challenging problem. In this paper, we propose a novel LiDAR-camera calibration method aiming to eliminate these two constraints. Specifically, we capture a scan of 3D LiDAR when both the environment and the sensors are stationary, then move the camera to reconstruct the 3D environment using the sequentially obtained images. Finally, we align 3D visual points to the laser scan based on tightly couple graph optimization method to calculate the extrinsic parameters between LiDAR and camera. Under this design, the configuration of these two sensors are free from the common field of view constraint owing to the extended view from the moving camera. And we also eliminate the requirement for strict time synchronization as we only use the single scan of laser data when the sensors are stationary. We theoretically derive the conditions of minimal observability for our method and prove that the accuracy of calibration is improved by collecting more observations from multiple scattered calibration targets. We validate our method on both simulation platform and real-world datasets. Experiments show that our method achieves higher accuracy than other comparable methods, which is in accordance with our theoretical analysis. In addition, the proposed method is beneficial to not only plane measurement error based chessboard, but also other point measurement error based calibration targets, such as boxes and polygonal boards.

description: We derive the tunneling rate for paramagnetic molecules in the context of a collective spin model. By means of path integral methods an analytical expression is derived. Given the very large spins in question (s ~ 3000 hbar), the observation of magnetization changes due to pure unitary tunnel effects is unlikely.

description: Sussex Archaeological Collections, 134, 179-183
description: This article examines the dispute, 1792-7, between Sir Richard Hotham and his former friend the Revd Thomas Durnford, vicar of South Bersted, over the licensing of Hotham's private chapel. The dispute is the sub;ect of a collection of correspondence of Archbishop Moore held at Lambeth Palace Library. The collection includes details of the agreement hastily negotiated after reconciliation in 1797, although how the reconciliation was procured remains a mystery. The particular issue explored here is why Hotham chose not to resolve the matter normally by Act of Parliament. Instead, he prolonged hostilities by prevaricating over the degree of public use he intended for his private chapel, seeking to accommodate the distinguished visitors to his newly-created seaside resort.
An Experimental Study of Shor's Factoring Algorithm on IBM Q

description: We study the results of a compiled version of Shor's factoring algorithm on the ibmqx5 superconducting chip, for the particular case of $N=15$, $21$ and $35$. The semi-classical quantum Fourier transform is used to implement the algorithm with only a small number of physical qubits and the circuits are designed to reduce the number of gates to the minimum. We use the square of the statistical overlap to give a quantitative measure of the similarity between the experimentally obtained distribution of phases and the predicted theoretical distribution one for different values of the period. This allows us to assign a period to the experimental data without the use of the continued fraction algorithm. A quantitative estimate of the error in our assignment of the period is then given by the overlap coefficient.

description: This dissertation traces the tensions surrounding indie music production in Santiago, Chile and Sao Paulo, Brazil. I conducted several years of ethnographic research on locally situated, yet transnationally interpolated, musical production, circulation and listening practices in Santiago and Sao Paulo. I open by detailing the expansion of the indie touring market from the global north into both cities, theorizing the enlistment of affect as a neoliberal technique for producing monetary value. The next chapter considers spaces for musical association as forms of infrastructure that both emerge from and themselves help constitute musical-social networks in Santiago. I follow by showing how the history of Brazilian individuals' engagement with particular sets of indie sounds from the global north bear upon the contemporary formation of infrastructures of social relations, musical aesthetics, and places for musical and social association. Finally, I detail how the tensions between the construction of audience, value, aesthetics and circulation arising from new production structures manifest in the politics of a new type of Brazilian institution called Fora do Eixo. Here, I inspect the logics of aesthetic valuation in building structures for music production within a complex state-private nexus of cultural funding in Brazil. As a whole, this dissertation explores the political struggles emerging as actors seek to establish new structures for participating in live shows and for playing music as both a creative practice and as an economic activity within emerging forms of communication and cultural circulation made possible by digital media. Each struggle is simultaneously interpolated by the messy articulation of transnationally-produced notions of aesthetics, authentic modes of engagement with music, and moral-ethical ways of organizing music production, circulation and remuneration as a social practice. The dissertation thus highlights the way new media and economic logics build upon and clash with historical practices of production, evaluation of aesthetics, and regimes for mediating the artistic, the economic, and the social.
Quantum fields interacting with colliding plane waves: the stress-energy tensor and backreaction

description: Following a previous work on the quantization of a massless scalar field in a spacetime representing the head on collision of two plane waves which fucus into a Killing-Cauchy horizon, we compute the renormalized expectation value of the stress-energy tensor of the quantum field near that horizon in the physical state which corresponds to the Minkowski vacuum before the collision of the waves. It is found that for minimally coupled and conformally coupled scalar fields the respective stress-energy tensors are unbounded in the horizon. The specific form of the divergences suggests that when the semiclassical Einstein equations describing the backreaction of the quantum fields on the spacetime geometry are taken into account, the horizon will acquire a curvature singularity. Thus the Killing-Cauchy horizon which is known to be unstable under ``generic" classical perturbations is also unstable by vacuum polarization. The calculation is done following the point splitting regularization technique. The dynamical colliding wave spacetime has four quite distinct spacetime regions, namely, one flat region, two single plane wave regions, and one interaction region. Exact mode solutions of the quantum field equation cannot be found exactly, but the blueshift suffered by the initial modes in the plane wave and interaction regions makes the use of the WKB expansion a suitable method of solution. To ensure the correct regularization of the stress-energy tensor, the initial flat modes propagated into the interaction region must be given to a rather high adiabatic order of approximation.
