A lot happens when we press play. To prepare, we select a particular format of sound storage—maybe vinyl, magnetic tape, polyethylene, or an mp3—for the parsing, processing, and amplification of that format's content. Once things start moving, we inaugurate a listening experience that may seem effortless, but which has undergone meticulous social conditioning, and which is informed by our own deep histories of listening, aurality, and attention. In the long term, this process is not as rigid as it sounds: listening has always been flexible, and historians of the concert hall have told us a twisting and turning story about audiences who did not always think it was proper to stay silent, and who did not always feel the need to pay much attention to what took place in front of them. But today, anyone who chooses to play a spoken word compilation instead of a jazz LP (long-playing record) at a cocktail party might not find such a receptive crowd. Facilitated by internet streaming and downloading, this relatively new ability to amass intensely personal sonic archives often clashes with the contextual demands of where, when, and how certain forms of listening are meant to be enacted: the cocktail party often dictates a particular aural accompaniment, one more amenable to music than an audiobook. For such a widely practiced activity, why do the modern activities of storing, distributing, and amplifying sound, which have grown kaleidoscopically complex in the twentieth and twenty-first centuries, remain undertheorized in Slavic studies? What would it mean to think about these questions and their repercussions in east European modernity? And what might listening to east European history and culture tell us that our other senses cannot?
We performed numerical simulations of the common envelope (CE) interaction between two intermediate-mass asymptotic giant branch (AGB) stars and their low-mass companions. For the first time, formation and growth of dust in the envelope is calculated explicitly. We find that the first dust grains appear as early as ∼1–3 yrs after the onset of the CE, and are smaller than grains formed later. As the simulations progress, a high-opacity dusty shell forms, resulting in the CE photosphere being up to an order of magnitude larger than it would be without the inclusion of dust. At the end of the simulations, the total dust yield is ∼8.2×10−3 M⊙ (∼2.2×10−2 M⊙) for a CE with a 1.7 M⊙ (3.7 M⊙) AGB star. Dust formation does not substantially lead to more mass unbinding or substantially alter the orbital evolution.
Magnetic fields are important physics in stellar evolutionary theory, which seriously affects the stellar structure and evolutionary statues. The small-scale magnetic fields in the photosphere are ubiquitous, and float on the stellar surface, which usually couple with the acoustic waves, affecting the propagation of the acoustic waves. Considering the effect of the magnetic fields in the stellar photosphere on the oscillation frequencies, we calculate the asteroseismology for solar-like star KIC 11295426 and KIC 10963065. We obtain the stellar fundamental parameters, especially the strength of small-scale magnetic fields in the stellar photosphere. We find that the small-scale magnetic fields in the stellar photosphere may obviously improve the agreement between the observations and the theoretical models for two stars. The magnetic strength for KIC 11295426 and KIC 10963065 from asteroseismology are in agreement with the stellar period-activity relation.
Planetary nebulae (PNe) are remnants of evolved stars, fundamental for understanding stellar life cycles and galactic enrichment. In this work, we present a summary of our recent work using three-dimensional models and spatially resolved constraints to examine the physical and chemical properties of PNe, with a particular focus on preliminary results for the PN NGC 3132. Our results indicate that a star of about 3M⊙, surrounded by a shell, wind, or disk with approximately 5.0×10−6M⊙ and extending to about 300AU is necessary to adequately reproduce the observations, consistent with recent JWST findings. We also discuss the importance of this methodology in studying the properties of the progenitor stars and making abundance determinations.
Haemodynamic changes in caval venous flow distribution occurring during bidirectional cavopulmonary anastomosis operation are still largely unknown.
Methods:
Transit time flow measurements were performed in 15 cavopulmonary anastomosis operations. Superior and inferior caval vein flows were measured before and after the cavopulmonary anastomosis. Ratio of superior caval vein to overall caval veins flow was calculated.
Results:
Mean superior caval vein flow ratio before cavopulmonary anastomosis was higher than previously reported for healthy children. Superior caval vein flow ratio decreased in 14/15 patients after cavopulmonary anastomosis: mean 0.63 ± 0.12 before versus 0.43 ± 0.14 after. No linear correlation between intraoperative superior caval vein pressure and superior caval vein flow after cavopulmonary anastomosis was found. Neither Nakata index nor pulmonary vascular resistance measured at preoperative cardiac catheterisation correlated with intraoperative flows. None of patients died or required a take down.
Conclusions:
The higher mean superior caval vein flow ratio before cavopulmonary anastomosis compared to healthy children suggests flow redistribution in univentricular physiology to protect brain and neurodevelopment. The decrease of superior caval vein flow ratio after cavopulmonary anastomosis may reflect the flow redistribution related to trans-pulmonary gradient. The lack of correlation between superior caval vein pressure and superior caval vein flow could be explained by limited sample size and multifactorial determinants of caval veins flow, although pressure remain essential. Larger sample of measurements are needed to find flow range potentially predictive for clinical failure. To authors’ knowledge, this is the first intraoperative flow measurement of both caval veins during cavopulmonary operations.
This article investigates the ideas of New Phenomenology, as developed by Hermann Schmitz. Schmitz distinguishes between the physical body that can be seen and touched, and the felt body that is the place of affective involvement. By locating the felt body as the basis of all human experience, Schmitz radically transcends the division between subject and object in favour of understanding human relations with the world as a question of embodied communication and meaningful situations. Basic principles of philosophical phenomenology, as described by Edmund Husserl and Martin Heidegger, are outlined, and New Phenomenology as conceived by Schmitz is presented. The aim is to investigate the relation of human being to the built environment. The Church of St Peter in Klippan designed by Sigurd Lewerentz, the Salk Institute in San Diego designed by Louis Kahn, and the Nordic Pavilion in Venice designed by Sverre Fehn are described, analysed, and discussed through the lens of New Phenomenology. The findings are located in relation to various scholarly writings on phenomenology in architecture, and it is argued that the content of the work of architecture may be emotionally gripped as meaningful presencing in specific situations. It is concluded that – in a world where we desperately need to rethink human relation to the environment in general, and the architect’s relation to building in particular – New Phenomenology can draw attention to human and environment as intrinsically connected. As such, understanding architecture in terms of embodied communication and meaningful situations may be one way to activate environmental awareness.
Unmet legal needs contribute to housing, income, and food insecurity, along with other conditions that harm health and drive health inequity. Addressing health injustice requires new tools for the next generations of lawyers, doctors, and other healthcare professionals. An interprofessional group of co-authors argue that law and medical schools and other university partners should develop and cultivate Academic Medical-Legal Partnerships (A-MLPs), which are uniquely positioned to leverage service, education, and research resources, to advance health justice.
For any emerging pathogen, the preferred approach is to drive it to extinction with non-pharmaceutical interventions (NPI) or suppress its spread until effective drugs or vaccines are available. However, this might not always be possible. If containment is infeasible, the best people can hope for is pathogen transmission until population level immunity is achieved, with as little morbidity and mortality as possible.
Methods:
A simple computational model was used to explore how people should choose NPI in a non-containment scenario to minimize mortality if mortality risk differs by age.
Results:
Results show that strong NPI might be worse overall if they cannot be sustained compared to weaker NPI of the same duration. It was also shown that targeting NPI at different age groups can lead to similar reductions in the total number of infected, but can have strong differences regarding the reduction in mortality.
Conclusions:
Strong NPI that can be sustained until drugs or vaccines become available are always preferred for preventing infection and mortality. However, if people encounter a worst-case scenario where interventions cannot be sustained, allowing some infections to occur in lower-risk groups might lead to an overall greater reduction in mortality than trying to protect everyone equally.
The aim of our paper is to study some aspects of the textile industry of the city of Segovia and its land in the second half of the 16th century, interpreting them through spatial economy theories and specifically the industrial district approach. It is about seeing the competitive advantages of the integration and diffusion of the business organization in its geographical framework. The district's competitive advantages are linked to both transaction and production costs. One of them is to maximize the benefits of labor market segmentation with the emergence of a primary market for skilled labor. Another is the ease of diffusion of both technology and organizational and commercial techniques.
Governments in developed nations today collect high tax revenues and spend vast amounts on security, regulation, infrastructure, and social programs. Yet developed nations were in no way born with effective state institutions. What explains the emergence of the modern state? And, why did capable states first form historically in Western Europe? Proper answers to these questions are key to our understanding of modern forms of governance, including parliamentary democracy.
Adoniram Judson is widely perceived as the pioneer Bible translator in Burma. His translation of the entire Bible into Burmese, however, built upon three centuries of Roman Catholic missionary outreach. Catholic priests had arrived as chaplains for Portuguese immigrants to Burma in the early sixteenth century, but an indigenous Burmese Catholic church was established within a generation through intermarriage. Barnabite missionaries arrived in the early eighteenth century and engaged in a dynamic hundred years of missionary work. These Catholic missionaries developed key Christian terminology and discourse that Judson drew upon in his translation work. British Baptists were also in Burma for several years before Judson arrived and made their own contribution to Burmese Bible translation. An analysis of the Burmese translations of the Lord's Prayer by Barnabite missionary Giovanni Maria Percoto (1776), British Baptist James Chater (1812), and Judson (1817 and 1832) demonstrates how Judson both drew upon and developed the work of his predecessors in his immense project of translating the entire Bible into Burmese (1840). The Judson Bible, still the most widely used and highly esteemed version in modern-day Myanmar, is an intertextual production. Literary and oral texts, all shaped by their historical settings, intersected multiple other texts over a period of three hundred years before flowing into Judson's translation.
