Published: September 2023

AbstractThe issue of vaccine hesitancy has posed a significant challenge during the Covid-19 pandemic, as it increases the risk of undermining public health interventions aimed at mitigating the spread of the virus. While the swift development of vaccines represents a remarkable scientific achievement, it has also contributed to skepticism and apprehension among some populations. Against this backdrop, the suspension of the AstraZeneca vaccine by the European Medicines Agency further exacerbated an already contentious debate around vaccine safety. This paper examines the Twitter discourse surrounding Covid-19 vaccines, focusing on the temporal and geographical dimensions of the discussion. Using over a year’s worth of data, we study the public debate in five countries (Germany, France, UK, Italy, and the USA), revealing differences in the interaction structure and in the production volume of questionable and reliable sources. Topic modeling highlights variations in the perspectives of reliable and questionable sources, but some similarities across nations. Also, we quantify the effect of vaccine announcement and suspension, finding that only the former had a significant impact in all countries. Finally, we analyze the evolution of the communities in the interaction network, revealing a relatively stable scenario with a few considerable shifts between communities with different levels of reliability. Our results suggest that major external events can be associated with changes in the online debate in terms of content production and interaction patterns. However, despite the AZ suspension, we do not observe any noticeable changes in the production and consumption of misinformation related to Covid-19 vaccines.
A Trilemma for the Singularitarian
Authors: Chen Melvin 
Published: September 2023

AbstractSingularitarianism is a view that is grounded in certain claims about the technological singularity. In this paper, I identify a trilemma that confronts singularitarianism. This trilemma may be characterized in terms of the following horns: the concept of a technological singularity having a literal sense, the concept of a technological singularity having a metaphorical sense, and the concept of a technological singularity having neither a literal nor a metaphorical sense (i.e., its being nonsensical). I will outline the unpalatable consequences that are associated with each of these three horns of the trilemma. I will also anticipate a few argumentative moves on behalf of singularitarianism and suggest why these moves may be insufficient. I will conclude by arguing that we have good philosophical grounds to defend an eliminativism about the concept of the technological singularity.

Chemical Range of Stability for Self-Dusting Ladle Furnace Slags and Destabilizing Effect of Sulfur
Authors: Mombelli D. , Dall’Osto G. , Fumagalli A. , Mapelli C. 
Published: September 2023

AbstractLadle furnace slags are characterized by volumetric expansions associated with the transition of dicalcium silicate (C2S) from β to γ phase, which generates fine dust during cooling, causing handling and storage issues that further reduce their recycling opportunities. The present work focuses on the effect of slag basicity on dusting and the role of sulfur on slag stability. Seven synthetic ladle slag precursors were made by mixing lime, magnesia, quartz and alumina in different proportions to match effective industrial compositions, increasing the binary basicity and keeping the ternary and quaternary indexes unchanged. Samples were heated to 1500 °C for 15 min and monitored during air cooling (< 5 °C/s) through thermocouples and camera to characterize the behavior, temperature, and time interval of dusting. The cooled samples were characterized chemically, mineralogically and morphologically. Starting from the chemistry of a self-stabilized slag, five additional slag precursors, characterized by increasing amounts of S, were created and analyzed using the same procedures. Experimental evidence showed the presence of three different dusting behaviors (stable, partial and complete) and stabilization of the slag once an optical basicity of 0.748 or higher was reached. In addition, mayenite was identified as the main phase capable of suppressing the β to γ transition by exerting hydrostatic pressure on C2S. Finally, although S can stabilize the β phase when dissolved in it, after saturation it precipitates as CaS, which can react with mayenite, locally decreasing the optical basicity and allowing dusting.

Prediction of uniaxial compressive strength of the Kızılkaya ignimbrite with variable properties using MRA and ANN, Cappadocia (Turkey)
Authors: Deniz Burcu Ertas , Topal Tamer 
Published: September 2023

AbstractCappadocia in Turkey is an important region with emphasis on ethnic and historic structures and geological features. Because of volcanic eruptions, ash flow materials deposited at different levels. These different colored ignimbrite levels have a wide range of geomechanical properties. In the region, the Kızılkaya ignimbrite covers a very large area and is frequently used as building dimension stone in for the restoration of old historical buildings such as churches, caravansaries and mosques as well as new buildings. It contains tuffaceous matrix with some minerals and rock fragments. The rock has variable character. In this study, the relationship between petrographic and physico-mechanical properties of the Kızılkaya ignimbrite was investigated. Rate of change between uniaxial compressive strength and the other index properties of the rock was statistically examined utilizing multiple regression analysis (MRA) and Artificial Neural Network (ANN) methods. The study has shown that uniaxial compressive strength (UCS) of the ignimbrite can be successfully estimated by the use of dry unit weight, effective porosity, sonic velocity, and grain matrix ratio (GMR) parameters. A new UCS prediction equation is proposed in this paper for the ignimbrite with variable character. Since properties of the ignimbrite at different distances from the eruption area changes significantly, the approach presented in this study can be considered for the ignimbrites especially covering a large area with different welding degrees and grains.

Abstract
For the first time in history, the United States surpassed 100 000 overdose-related deaths in a 12-month period, driven by synthetic opioids such as fentanyl. Also, for the first time, potential chemical weapons are readily available on the streets and the dark web. Opioids represent a rare trifecta, used for licit pain management, as an illicit drug of abuse, and with potential use as a weapon of terror. Community-based Response to Drug Overdose (CReDO) is an initiative to unite agencies, disciplines, government, and private partners in 1 coordinated opioid emergencies response plan under nationwide standards, and can be integrated into the disaster medicine discipline due to the risk of mass casualty incidents involving fentanyl or its derivatives. Attention to the opioid crisis through CReDO will save lives by promoting information sharing between disciplines, shortened response time to overdose clusters, community collaboration to identify criminal distribution networks, and holistic approaches to addiction.
Confidence in China’s political system was linked to perception of Covid infection risk, Covid health threat, and attitudes toward dynamic Zero-Covid policy
Authors: Li King King , Hong Ying-yi 
Published: September 2023

Abstract
How was Chinese people’s confidence in the political system linked to their perception of Covid infection risk, perception of health threat of Covid infection, lockdown experience, and attitudes toward the dynamic Zero-Covid policy? Using 2 waves of online surveys conducted in 2020 and 2022, we investigated how these factors were related. Individuals who were more supportive of the Zero-Covid policy were more confident. Those who were less supportive of the Zero-Covid policy were from areas with more severe Covid infections and experienced a longer lockdown as well; these individuals also perceived higher Covid infection risk and health threat. As such, their confidence in the political system was also more likely to drop from 2020 to 2022. In sum, these findings suggest that Chinese people’s confidence in the political system was linked to their Covid infection risk perception, perceived Covid threat to health, lockdown experience, and attitudes toward the Zero-Covid policy. These findings were corroborated with the severity of Covid infections in the province and individual’s political beliefs and orientation.
Repeated exposure affects susceptibility and responses of Atlantic salmon (Salmo salar) towards the ectoparasitic salmon lice (Lepeophtheirus salmonis)

Published: September 2023

AbstractAtlantic salmon (Salmo salar) is repeatedly exposed to and infected with ectoparasitic salmon lice (Lepeophtheirus salmonis) both in farms and in nature. However, this is not reflected in laboratory experiments where fish typically are infected only once. To investigate if a previous lice infection affects host response to subsequent infections, fish received 4 different experimental treatments; including 2 groups of fish that had previously been infected either with adult or infective salmon lice larvae (copepodids). Thereafter, fish in all treatment groups were infected with either a double or a single dose of copepodids originating from the same cohort. Fish were sampled when lice had developed into the chalimus, the pre-adult and the adult stage, respectively. Both the specific growth rate and cortisol levels (i.e. a proxy for stress) of the fish differed between treatments. Lice success (i.e. ability to infect and survive on the host) was higher in naïve than in previously infected fish (pre-adult stage). The expression of immune and wound healing transcripts in the skin also differed between treatments, and most noticeable was a higher upregulation early in the infection in the group previously infected with copepodids. However, later in the infection, the least upregulation was observed in this group, suggesting that previous exposure to salmon lice affects the response of Atlantic salmon towards subsequent lice infections.
‘With all praise to your exalted frequencies, consider me your friend’: listening, technology and musicking in the Church of Scientology
Authors: Wagner Tom 
Published: September 2023

AbstractThis article discusses musicking in the Church of Scientology, and how it can be used to understand the organisation and its relationship to society. The article begins by discussing the essential place oflisteningin Scientological practice, noting that it is one of several ‘technologies’ that institutionalise the charisma of its founder, L. Ron Hubbard. It next demonstrates how Hubbard's hagiography influences how the church produces music today. This leads to a consideration of the ‘whole track sound’ of Scientology and uses the albumHymn of Asia(2000) to discuss how Scientological concepts are embedded sonically and lyrically into the church's recorded music outputs. The final section discusses the importance ofcommunicationin Scientology's musical thought, using interviews drawn from my fieldwork in Los Angeles to highlight the benefits and limits of music as a medium of (religious) communication.

Abstract
Hepatitis E virus infection is a major cause of acute hepatitis, typically self-limiting but occasionally leading to liver failure. Understanding disease progression factors could inform prevention strategies. This study aimed to analyse the characteristics of a large cohort of hospitalised hepatitis E patients in Tianjin, China, and explore factors influencing their progression to liver failure. A total of 1279 hospitalised patients with hepatitis E were included in this cross-sectional study in Tianjin, China. Student's t-test and the Mann–Whitney U-test were used for comparisons. Multiple logistic regression analysis was used to explore the association. Among these 1279 patients, 107 (8.4%) developed liver failure. Patients with diabetes mellitus (DM) (95% confidence interval [CI] 1.150–2.887, p = 0.011), liver cirrhosis (95% [CI] 2.229–7.224, p < 0.001), and hepatitis B (95% [CI] 1.159–4.512, p = 0.017) were more likely to progress to liver failure. Hepatitis E patients with comorbid DM, liver cirrhosis, or hepatitis B virus co-infection have higher risks of developing liver failure. Hepatitis E vaccination may be recommended for these vulnerable patients to curb disease severity.

ResumenEl sitio de Tak'alik Ab'aj se encuentra en la bocacosta suroccidental de Guatemala. Durante las excavaciones del Entierro 1 de la Estructura 7A, fechado para finales del preclásico tardío (150 d.C.), se recuperó un rico ajuar funerario compuesto por decenas de piezas de jadeitita, hematita, pirita y cuatro mosaicos “reflectores” de este mismo material. Cada uno fue labrado con la misma tecnología de manufactura y soporte “flexible” de fragmentos de cerámica (ensamblados con resina) por primera vez documentado, y diseño propio para la función y significado que desempeñara. Dos de ellos fueron integrados en la pechera y faldellín del traje ceremonial; los otros dos como parte del ajuar adicional de un posible portaestandarte.En este trabajo se incluye el estudio traceológico-tecnológico de las teselas de estos mosaicos del Entierro 1 a través de la caracterización de sus huellas de manufactura con arqueología experimental y microscopías óptica y electrónica de barrido. De esta manera se detectó una elaboración muy estandarizada en la que se aprovecharon instrumentos hechos con rocas volcánicas locales, como la dacita, cuyo sello tecnológico no ha sido reportado hasta el momento en otra colección lapidaria maya.
Mirrors and reflective objects at Kaminaljuyu
Authors: Arroyo Bárbara 
Published: September 2023

AbstractSlate disks have been reported from various excavations in the Maya Highlands. These artifacts have typically been described as supports or backings for iron-ore and pyrite mirrors. A number of these objects have been recovered in context at Kaminaljuyu, Guatemala. Whenever objects with reflective surfaces are identified in the field, they tend to be interpreted as mirrors, but they may have been worn as insignia on clothing. Recent finds at Kaminaljuyu, such as special deposits associated with Ballcourt B, suggest the use of reflective objects as part of the ballgame player's paraphernalia. The ballgame was an important ritual practice at Kaminaljuyu, as exemplified by the 13 ballcourts reported at the site. Archaeological evidence for this new interpretation will be presented, as well as a review of other examples excavated throughout the highlands, as part of an exploration of the exchange networks connected to regional trade in these exotic goods.

AbstractDissolved organic matter (DOM) composition in lakes is controlled by multiple environmental drivers, but the relative importance of various drivers remains poorly understood at the continental scale. Here, we established a model resolving possible influencing pathways of climate, land cover, societal development, and water retention time of lakes on the quantity and quality of chromophoric DOM (CDOM) from 182 lakes spanning across strong climatic and economic gradients in China. Our results indicate that land cover and societal development both exhibit positive direct effects on lake CDOM quantity, highlighting the significant role of well‐vegetated soils and anthropogenic activities as sources of lake DOM on a continental scale. Climate has two strong but opposite effects—a warming and wet climate facilitates soil OM production and export, while it also enhances CDOM in‐lake transformation. Three proxies are proposed as indicators of the magnitude of biogeochemical drivers influencing lake DOM across different ecoclimatic zones, including fluorescent DOM/DOC indicating economic activity, percentages of a degraded fluorescent DOM component indicating solar irradiation, and percent tyrosine‐like DOM reflecting DOM processing time within the watershed and lake. Collectively, our findings indicate that the effects of climate change and rapid societal development will result in increased loadings of terrestrial and anthropogenic DOM into lakes and drive higher rates of within‐lake processing of DOM. Consequently, lakes will play a more important role as an “active pipe” in mediating the flux and transformation of organic carbon, intensifying the coupling between terrestrial and aquatic carbon cycles on a continental scale.
On the Relationship Between Regions of Large‐Scale Field‐Aligned Currents and Regions of Plateau in Plasma Pressure Observed in the Equatorial Plane of the Earth's Magnetosphere

Published: September 2023

AbstractSince the discovery of the large‐scale field‐aligned currents it is widely acknowledged that gaps exist between the Region 1 (R1) and Region 2 (R2) currents in which the current values are relatively small as compared to neighboring regions. Assuming that the field‐aligned currents are generated by plasma pressure gradients, we analyzed data collected by the THEMIS satellites between 2007 and 2011 to identify regions with very low plasma pressure gradients (pressure plateaus), which could be responsible for the appearance of these gaps. It was found that the pressure profiles with low radial gradients are typically located between 8 and 10 Radii around the Earth. Projections of pressure plateau regions onto ionospheric altitudes, for both individual events and on a statistical basis, coincide with the locations of gaps between Iijima and Potemra field‐aligned currents. The role played by identified pressure plateaus in shaping the pattern of large‐scale field‐aligned currents is discussed.
Evidence of a Transient Aseismic Slip Driving the 2017 Valparaiso Earthquake Sequence, From Foreshocks to Aftershocks

Published: September 2023

AbstractFollowing laboratory experiments and friction theory, slow slip events and seismicity rate accelerations observed before mainshocks are sometimes interpreted as evidence of a nucleation phase. However, such precursory observations still remain scarce and are associated with different time and length scales, raising doubts about their actual preparatory nature. We study the 2017 Valparaiso Mw = 6.9 earthquake, which was preceded by aseismic slip accompanied by an intense seismicity, suspected to reflect its nucleation phase. We complement previous observations, which have focused only on precursory activity, with a continuous investigation of seismic and aseismic processes from the foreshock sequence to the post‐mainshock phase. By building a high‐resolution earthquake catalog and searching for anomalous seismicity rate increases compared to aftershock triggering models, we highlight an over‐productive seismicity starting within the foreshock sequence and persisting several days after the mainshock. Using repeating earthquakes and high‐rate GPS observations, we highlight a transient aseismic perturbation starting 1‐day before the first foreshock and continuing after the mainshock. The estimated slip rate over time is lightly impacted by large magnitude earthquakes and does not accelerate toward the mainshock. Therefore, the unusual seismic and aseismic activity observed during the 2017 Valparaiso sequence might be interpreted as the result of a slow slip event starting before the mainshock and continuing beyond it. Rather than pointing to a possible nucleation phase of the 2017 Valparaiso mainshock, the identified slow slip event acts as an aseismic loading of nearby faults, increasing the seismic activity, and thus the likelihood of a large rupture.
