Abstract Using molecular dynamics simulations, the ratio of ternary to binary collision densities is investigated for both a hard-sphere gas and a Lennard-Jones gas. The simulations confirm the existing theoretical models for the hard-sphere gas but reveal temperature dependence of collision density ratio in a Lennard-Jones gas. A theoretical model is developed to explain this temperature dependence.

This article identifies an emerging genre of police body camera content that we term “participatory policing”: social media videos composed from official police footage, obtained through Freedom of Information Act (FOIA) requests, and transformed into viral entertainment by amateur content creators who add narration, sound, and visual effects. Through an analysis of videos, viewer comments, and the broader media ecosystem surrounding the YouTube channel Code Blue Cam (2021–present), we demonstrate how this genre valorizes law enforcement while stigmatizing criminalized “others.” We argue that three key features—the “the body cam gaze” (our term for the first-person perspective from police body-worn cameras), creator editing and commentary, and active viewer participation—work together to extend police surveillance and disciplinary power beyond traditional law enforcement. By inviting audiences to surveil, categorize, and judge police targets, this genre inculcates viewers into the disciplinary apparatus of surveillance culture.

they were mostly large, successful, and most either were publications or resulted in publications, so they influenced others, both at Penn and beyond.Even the smallest, the Codes in Context conference, was successful, in that it was organized, held, and as demonstrated, at least some participants used the phrase later.(Students who were at Penn in the 1970s remember hearing the phrase, and one of the core topics in the doctoral program at Annenberg at the time was named "Communication Codes and Modes." 1 ) However, in addition to these, there were multiple less significant and/or unsuccessful collaborations at Penn involving Goffman.Mostly these efforts were intended to coordinate activities across departments at Penn; their story forms the majority of this chapter.These activities are justifiably called minor primarily because they either had fewer substantial results (especially in terms of funding and/or publication, thus influence both across and beyond Penn) or because they were attempted but failed, yet all of them are part of the larger story to be told of Goffman's invisible college at Penn.There are also significant differences between the two types of projects in terms of timing, involvement, and commitment.In terms of timing, most of the major projects were begun in the late 1960s and early 1970s, while most of these minor projects were begun in the late 1970s.In terms of involvement, nearly everyone in the primary peer group was involved in all the major projects in some capacity, but only some were involved in the minor projects.In terms of commitment, all the

ABSTRACT Through a partnership between a local heritage foundation, an active archaeological field project, and a museum, we developed a novel educational programme for schoolchildren to introduce the full life-cycle of archaeological artifacts. Our programme demystifies heritage knowledge construction and presentation at the same time. During the summers of 2022 and 2023, multiple groups of children aged 7–15 visited an excavation and a museum in Armenia. Over the course of four days, each group gained hands-on experience while excavating on-site, conducting lab work and analysis, restoring their finds, and creating an actual public museum exhibit. Formal and informal assessment preliminarily indicates the effectiveness of the programme in providing a baseline of knowledge to support the public's involvement in future heritage-based decision-making. Our project also serves as an example of collaboration among a variety of different types of archaeological and heritage organizations.

Abstract Legionella pneumophila is an opportunistic bacterial pathogen that causes Legionnaires’ disease. To establish an intracellular niche conducive to replication, L. pneumophila translocates a diverse array of effector proteins that manipulate various host cellular processes, including the actin cytoskeleton. In a screen for effectors that alter actin dynamics, we identified a Legionella effector, Lfat1, which colocalizes with the actin cytoskeleton in eukaryotic cells. Lfat1 specifically binds F-actin through a novel actin-binding domain (ABD). High-resolution cryo-electron microscopy (cryoEM) analysis revealed that this ABD forms a long α-helix hairpin, with its tip interacting with subdomains I and II of two adjacent actin molecules within the F-actin filament. Interestingly, while individual α-helices of the hairpin fail to bind F-actin, co-expression as separate fusion proteins restores binding activity. Furthermore, we demonstrated that Lfat1 exhibits lysine fatty-acyltransferase (KFAT) activity, targeting host small GTPases. These findings establish a foundation for studying the KFAT family of bacterial toxins and uncover a novel F-actin binding motif, providing an alternative F-actin marker with notable flexibility.

Purpose: The purpose of this study was to analyze the evolution of home advantage (HA) effect in NCAA D1 men's soccer (2010-2020) in relation to the level of a team. Research Design: The studied variables were result of the game, location of the game (home, away or neutral), winning percentage, the level of the team according to its winning percentage (high level, mid-level, or low level), the level of the opponent team, type of confrontation considering the level of the teams (1vs1, 1vs2, 1vs3, 2vs2, 2vs3, and 3vs3), team home points advantage, team goals, assists, shot attempts, shots on goal, efficacy (percentage of shots scored), penalties, corners, fouls, yellow cards, and red cards. Sample: The sample was all 39,397 NCAA Division 1 men's soccer matches from the 2010-2011 season to the 2019-2020 season. Results: Regardless of the strength of the team (level of team and type of confrontation), teams won significantly more games when playing at home compared to playing away. Comparing home point advantage, low level teams had a significantly higher home advantage effect than middle level teams. When playing at home, teams had significantly more goals, assists, shot attempts, shots on goal, and corners, while conceding fewer goals. All the differences found had a small effect size. The fact that neutral games didn't evince any significant differences, further supports the notion of the HA-effect. Conclusions: This study confirms the HA effect and presents reference values according to team strength and confrontations regarding win-loss-tie, home advantage points, and game statistics.

Our paper examines CO2 emissions resulting from energy consumption across key sectors: commercial, industrial, transportation, residential, and electrical. We emphasize predicting CO2 output associated with diverse fuel types used within these sectors. Leveraging extensive datasets from the Energy Information Administration and the Environmental Protection Agency, we utilize energy consumption data, measured in Trillion Btu units, to build predictive models that forecast future CO2 emissions. By analyzing the correlation between energy use and CO2 output, our study provides critical insights into the environmental impact of different fuel sources. We incorporate the polluting factors of each energy type to estimate their individual contributions to overall emissions. These models empower stakeholders to make informed decisions regarding energy use, fostering proactive environmental control. Our work advocates for sustainable energy practices by identifying opportunities for reducing CO2 emissions while emphasizing the importance of mindful consumption. The findings encourage transitioning to environmentally friendly energy alternatives and promote collective action toward mitigating climate change. Ultimately, this research underscores the need for balancing energy demands with environmental stewardship, aiming to inspire practices that contribute to a greener, more sustainable future for current and future generations.
