HONK! : a street band renaissance of music and activism
\"HONK! Music Activism in a Street Band Renaissance reflects on the recent, transnational revival of street bands. It provides a window into diverse manifestations of cultural activity that mobilizes communities to reimagine the public square, protest injustice, and celebrate community. With the joy of participatory music making at its core, HONK bands are a fast-growing phenomena, asserting their activism through \"radical inclusion,\" active musical engagement in street protests, and grassroots organization. This collection of twenty-two essays, voiced in various local contexts, describes how the diversity of manifestations of these movements parallels the rich diversity of the musical repertoires these bands play and share. The HONK! Festival of Activist Street Bands began in Somerville, Mass, in 2006 as an independent, non-commercial, street festival, featuring community-based brass and percussion bands. HONK has since spread to three continents. The contributors tackle a diverse range of themes, including circulation of repertoire, innovative musical pedagogies, musical engagement within protest, and various theories of activism, incl. the social dynamics of gender, race, and class. Musicians, activists, and scholars engage with how HONK! Festivals might pursue their goals of \"changing the world.\"\"-- Provided by publisher.

Antiviral and Immunomodulatory Activity of Silver Nanoparticles in Experimental RSV Infection
Respiratory syncytial virus (RSV) is an important etiological agent of respiratory infection in children for which no specific treatment option is available. The RSV virion contains two surface glycoproteins (F and G) that are vital for the initial phases of infection, making them critical targets for RSV therapeutics. Recent studies have identified the broad-spectrum antiviral properties of silver nanoparticles (AgNPs) against respiratory pathogens, such as adenovirus, parainfluenza, and influenza. AgNPs achieve this by attaching to viral glycoproteins, blocking entry into the host cell. The objective of this study was to evaluate the antiviral and immunomodulatory effects of AgNPs in RSV infection. Herein we demonstrate AgNP-mediated reduction in RSV replication, both in epithelial cell lines and in experimentally infected BALB/c mice. Marked reduction in pro-inflammatory cytokines (i.e., IL-1α, IL-6, TNF-α) and pro-inflammatory chemokines (i.e., CCL2, CCL3, CCL5) was also observed. Conversely, CXCL1, G-CSF, and GM-CSF were increased in RSV-infected mice treated with AgNPs, consistent with an increase of neutrophil recruitment and activation in the lung tissue. Following experimental antibody-dependent depletion of neutrophils, the antiviral effect of AgNPs in mice treated was ablated. To our knowledge, this is the first in vivo report demonstrating antiviral activity of AgNPs during RSV infection.

Insights Into the Ecology of a Widespread but Poorly Known Aerial Insectivore and a Theoretical Basis for Range Expansion Following Repeated Vagrancy Events
Over the course of the last two centuries, Northern Rough‐winged Swallows (Stelgidopteryx serripennis) have expanded their range across the North American continent but have remained a relatively poorly known species. In this paper, I discuss two aspects of their nature history that has received little attention. First, I document an instance of Northern Rough‐winged Swallows digging their own burrow, which was for the better part of the last century considered a behavior that was either lost or never occurred in the first place. Second, I review the natural history literature to document qualitative patterns evident in their expansion over the last two centuries. In doing so, I define three potentially useful concepts that can he applied to understand species' range shifts: an Expansion Chronology, which is a spatiotemporal map of a range shift; the concept of Vagrancy‐induced Range Expansion, where a species undergoes repeated movements outside of their typical geographic range (defined as vagrancy events), leading to the regular occurrence in a new region (e.g., regular overwintering or nonbreeding occurrences); and the concept of Vagrancy‐induced Long‐distance Dispersal, which is specifically expansion of a species' breeding range following repeated vagrancy events. Northern Rough‐winged Swallows are a widespread but poorly known aerial insectivore. Historically thought to only use the cavities of other species to nest, this paper confirms that they do in fact have the ability to excavate their own nesting burrows. Furthermore, this paper delves into the idea that the spread of urban areas across North America during the Gilded Age contributed to their range expansion, and the reduced need to dig their own burrows. Additionally, using the dispersal literature, the paper defines the pattern of expansion displayed by Northern Rough‐winged Swallows as Vagrancy‐induced Range Expansion.

Singular purpose: Calculating the degree of ethno-religious over-representation in the US no-fly list
In January 2023, a partially redacted version of the controversial US No-Fly List was retrieved during a hacking event and made available to journalists and academics. With access to this unique dataset, it is possible to confirm or deny longstanding critiques of whether the No-Fly List features a discriminatory over-representation of certain ethno-religious groups, namely those of Islamic faith and Middle Eastern heritage. As the partially redacted list does not contain ethnic or religious data, the author of this article categorised each name by ethno-linguistic and religious origin to create a proxy with which to analyse claims of discrimination. The research outlined in this article finds that individuals of broadly Islamic and Middle Eastern heritage are vastly overrepresented on the List relative to their proportion of the US population, as well as overrepresented relative to their propensity to engage in terrorism. Only in the narrow analysis of lethality of terrorist attacks committed by this group does the No-Fly List demonstrate fair representation.

A note on monotonicity and Bochner formulas in Carnot groups
In this note, we prove two monotonicity formulas for solutions of $\\Delta _H f = c$ and $\\Delta _H f - \\partial _t f = c$ in Carnot groups. Such formulas involve the right-invariant carré du champ of a function and they are false for the left-invariant one. The main results, theorems 1.1 and 1.2, display a resemblance with two deep monotonicity formulas respectively due to Alt–Caffarelli–Friedman for the standard Laplacian, and to Caffarelli for the heat equation. In connection with this aspect we ask the question whether an ‘almost monotonicity’ formula be possible. In the last section, we discuss the failure of the nondecreasing monotonicity of an Almgren type functional.

An Efficient Pipeline to Obtain 3D Model for HBIM and Structural Analysis Purposes from 3D Point Clouds
The aim of this work is to identify an efficient pipeline in order to build HBIM (heritage building information modelling) and create digital models to be used in structural analysis. To build accurate 3D models it is first necessary to perform a geomatics survey. This means performing a survey with active or passive sensors and, subsequently, accomplishing adequate post-processing of the data. In this way, it is possible to obtain a 3D point cloud of the structure under investigation. The next step, known as “scan-to-BIM (building information modelling)”, has led to the creation of an appropriate methodology that involved the use of Rhinoceros software and a few tools developed within this environment. Once the 3D model is obtained, the last step is the implementation of the structure in FEM (finite element method) and/or in HBIM software. In this paper, two case studies involving structures belonging to the cultural heritage (CH) environment are analysed: a historical church and a masonry bridge. In particular, for both case studies, the different phases were described involving the construction of the point cloud and, subsequently, the construction of a 3D model. This model is suitable both for structural analysis and for the parameterization of rheological and geometric information of each single element of the structure.

Some Inequalities for the Fourier Transform and Their Limiting Behaviour
We identify a one-parameter family of inequalities for the Fourier transform whose limiting case is the restriction conjecture for the sphere. Using Stein’s method of complex interpolation, we prove the conjectured inequalities when the target space is

Southern breeding populations drive declining migration distances in Arctic and subarctic geese
Migration is a prevalent strategy among birds used to track seasonal resources throughout the year. Individual and population‐level migratory movements provide insight to life‐history variation, carry‐over effects, and impacts of climate change. Our understanding of how geographic variation in a species' breeding or wintering grounds can impact migration distances is limited. However, changes in migration distances can have important fitness consequences for individuals and conservation implications for populations, particularly if migratory connectivity is altered during the annual cycle. In this study, we use three decades of data from the United States Geological Survey Bird Banding Laboratory for six migratory species of Arctic and subarctic breeding geese. We employ a Bayesian hierarchical framework to test if the distance between breeding and wintering locations has changed over time, while accounting for the latitude of the breeding grounds. A model that included only a temporal trend estimated the average rate of change in migration distance, across all six species, at −3.0 km/year over the period 1990–2019. Five of the six species showed a significant decrease in migration distances. Including an interaction effect with breeding latitude revealed that the reduction in migration distance was strongest in the southernmost populations for four of the six species. For those species, migration distance in northern populations were all either relatively unchanged or increasing. This indicates that southern breeding populations of geese had a stronger association with the observed spatiotemporal changes in wintering ranges, potentially influenced by a combination of climatic and biotic factors (e.g. resource availability or competitive interactions) that uniquely impact these populations. Abundant, long‐term banding data shows promise for use in illuminating changes in migratory patterns under climate change, leading to improved management and conservation outcomes, from regional to continental scales.
