Fossil capitate hydrozoans require exceptional conditions for preservation. Here we describe Bertratis ciurcae new genus, new species from the Silurian (Pridoli) of southern Ontario and upper New York State, where it occurs in association with a diverse assemblage of eurypterids. Only the float (pneumatophore) is well preserved, surviving as a thick carbonaceous compression. The new taxon is the largest fossil capitate reported, reaching a width of 17 cm, and the third Porpita-like example known from the Paleozoic. It was a rare pelagic component of the biota of the well-known Bertie Group Lagerstätten.
Bell ringing in Britain has featured in sociohistorical studies, but it has never been analyzed in detail as a variety of mass spectacle. The practice takes especially interesting forms in London, a city where the ringing of church bells has been part of everyday life for centuries. Grounded in physics, economics, and human geography, ringing is a unique kind of immersive site-specific performance, whose significance is best understood through pivoting to topography and history.
There is a balance between the amount of (weak) indestructibility one can have and the amount of strong cardinals. It’s consistent relative to large cardinals to have lots of strong cardinals and all of their degrees of strength are weakly indestructible. But this necessitates the destructibility of the partially strong cardinals. Guaranteeing the indestructibility of the partially strong cardinals is shown to be harder. In particular, this work establishes an equiconsistency between:
1. a proper class of cardinals that are strong reflecting strongs; and
2. weak indestructibility for (κ+2)-strength for all cardinals κ in the presence of a proper class of strong cardinals.
These have a much higher consistency strength than:
3. weak indestructibility for all degrees of strength for a proper class of strong cardinals.
This discrepancy holds even if we weaken (2) from the presence of a proper class to just two strong cardinals. (2) is also equivalent to weak indestructibility for all λ-strength for λ far beyond (κ+2); well beyond the next measurable limit of measurables above κ, but before the next μ that is (μ+2)-strong.
One direction of the equiconsistency of (1) and (2) is proven using forcing and the other using core model techniques from inner model theory. Additionally, connections between weak indestructibility and the reflection properties associated with Woodin cardinals are discussed, and similar results are derived for supercompacts and supercompacts reflecting supercompacts.
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?
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.
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.
