Authors: Sohn Jangjay , Shin Heean , Lee Joonnyong , Kim Hee Chan 
Published: December 2023

AbstractPhotoplethysmogram (PPG) performs an important role in alarming atrial fibrillation (AF). While the importance of PPG is emphasized, there is insufficient amount of openly available atrial fibrillation PPG data. We propose a U-net-based generative adversarial network (GAN) which synthesize PPG from paired electrocardiogram (ECG). To measure the performance of the proposed GAN, we compared the generated PPG to reference PPG in terms of morphology similarity and also examined its influence on AF detection classifier performance. First, morphology was compared using two different metrics against the reference signal: percent root mean square difference (PRD) and Pearson correlation coefficient. The mean PRD and Pearson correlation coefficient were 27% and 0.94, respectively. Heart rate variability (HRV) of the reference AF ECG and the generated PPG were compared as well. The p-value of the paired t-test was 0.248, indicating that no significant difference was observed between the two HRV values. Second, to validate the generated AF PPG dataset, four different datasets were prepared combining the generated PPG and real AF PPG. Each dataset was used to optimize a classification model while maintaining the same architecture. A test dataset was prepared to test the performance of each optimized model. Subsequently, these datasets were used to test the hypothesis whether the generated data benefits the training of an AF classifier. Comparing the performance metrics of each optimized model, the training dataset consisting of generated and real AF PPG showed a test accuracy result of 0.962, which was close to that of the dataset consisting only of real AF PPG data at 0.961. Furthermore, both models yielded the same F1 score of 0.969. Lastly, using only the generated AF PPG dataset resulted in test accuracy of 0.945, indicating that the trained model was capable of generating valuable AF PPG. Therefore, it can be concluded that the generated AF PPG can be used to augment insufficient data. To summarize, this study proposes a GAN-based method to generate atrial fibrillation PPG that can be used for training atrial fibrillation PPG classification models.
Trauma Level, Coping with Stress and Post-Traumatic Change in University Students Experiencing Kahramanmaraş Centered Earthquake: A Cross-Sectional Study
Authors: Bahar Aynur , Çuhadar Döndü 
Published: December 2023

Abstract

Objective:
The aim of this research is to examine the levels of post-traumatic stress, coping with stress, and post-traumatic change in university students after the Kahramanmaraş-centered earthquakes in February 2023.

Method:
The research is descriptive and relational. The sample of the study consists of 221 university students. Personal Information Form, Post-earthquake Trauma Level Determination Scale, Strategies for Coping with Earthquake Stress Scale, and Post-Traumatic Change Scale were used as data collection tools. Descriptive analyses (percentage, arithmetic mean), correlation analysis, and regression analysis were used in the analysis of the data.

Results:
It was determined that the students were highly traumatized after the earthquake, and post-traumatic stress symptoms were observed in a significant majority of the students. It was determined that the students used the post-earthquake coping strategies effectively. Post-traumatic change is positive. Inter-scale correlations are significant (P < 0.05). According to regression analysis, the level of post-earthquake trauma and the level of coping with earthquake stress are significant predictors of post-traumatic change. In addition, the damage to houses during the earthquake significantly affects the post-traumatic change.

Conclusions:
We think that pre-planning the psychological support services, increasing social supports, and teaching methods of coping with stress that can be applied after disasters such as earthquakes will be effective in preventing post-traumatic problems in university students at risk after trauma. It is hoped that the findings of this study will assist researchers, practitioners, and policymakers in implementing effective strategies for post-disaster.
A hydrozoan from the eurypterid-dominated Silurian Bertie Group Lagerstätten of North America
Authors: Larson Evelyn , Briggs Derek E.G. 
Published: December 2023

AbstractFossil 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.UUID: http://zoobank.org/1eb789e3-67b4-4e46-9baf-6320d4b67d6c
From Fitness-Centered to Trait-Centered Explanations: What Evolutionary Transitions in Individuality Teach Us About Fitness
Authors: Takacs Peter , Doulcier Guilhem , Bourrat Pierrick 
Published: December 2023

AbstractFitness has taken center stage in debates concerning how best to identify evolutionary transitions in individuality (ETIs). An influential framework proposes that an ETI occurs only when fitness is exported from constituent particles to a collective. We reformulate the conceptual structure of this framework as involving three steps. The culminating step compares “counterfactual” fitnesses against a long-run measure of fitness. This comparison assumes that collective-level fitness mereologically supervenes on particle fitness. However, if this assumption is rigorously enforced, the proposed conditions for identifying ETIs prove to be too weak. We here suggest an alternative model of ETIs centered around traits.
Synopsis of gastropod-associated nematodes of Ciscaucasia (Russian Federation) with the description of a new species of Pellioditis Dougherty, 1953 (syn. Phasmarhabditis Andrássy, 1976)
Authors: Ivanova E.S. , Spiridonov S.E. 
Published: December 2023

Abstract
Caucasus is known as one of the few biodiversity hotspots in Europe and is characterised by rich gastropod fauna while the nematode fauna in association with gastropods has remained largely understudied. Surveys conducted in 2019 and 2021 in the North Caucasus of the Russian Federation (Stavropol Upland and western and central parts of Krasnodar Krai) has revealed the presence of three new species of Pellioditis, a facultative parasite of land gastropods, and two species of obligate parasites, the intestinal parasite Angiostoma kimmeriense and a new, still undescribed species of a larval ectoparasite Alloionema sp. The new associations of Cruznema sp. and Rhabditophanes sp. with land gastropods were recorded for the first time in the Russian Federation. The new species of Pellioditis Dougherty, 1953 described here is based on the analysis of morphology and molecular studies of two distant and morphologically distinct strains, thermalis and sindicae. Pellioditis thermalis n. sp. was characterised by females possessing a tail of about 95–100 μm long, broadly conical in shape in the thermalis and sindicae strains, with a rounded anterior part and a subulate terminal part as long as the former; prominent phasmids located at the mid-tail, equatorial vulva position, a lateral field of three ridges (four incisions), males with spicules featuring a hole at the distal tip, ensheathed infective juveniles with average length 717 μm in the thermals strain and 771 μm in the sindicae strain, and exsheathed ones 644 μm and 682 μm, respectively. ITS-based phylogenetic analyses revealed that all Pellioditis species found in Ciscaucasia and Transcaucasia probably belong to two separate clades, with independent evolutionary histories of colonisation of this area. The entire Caucasus range area appears to serve as a biodiversity hotspot for the genus Pellioditis, presumably due to its complicated geological history and repeated isolation events for its terrestrial mollusc hosts.
HEALTH, HEIGHT AND REGIONAL DISPARITIES IN ITALY: EVIDENCE FROM CONSCRIPTS’ DATA, 1843-1871
Authors: Daniele Vittorio , Samà Francesco 
Published: December 2023

ABSTRACTThis article contributes to the debate on regional disparities in living standards in Italy at the time of national unification (1861) by examining the health standards of army conscripts born between 1843 and 1871. Data regarding the conscripts born in 1843-1856 show that 35.4 per cent of youths examined were unfit for military service. Overall, the rejection rate in the peninsular south was similar to that of the northern regions. In the south, however, the share of conscripts rejected for insufficient height was notably higher. It is very likely that the persistent north-south gradient in average height in Italy is related to genetic factors.
What is attractive about becoming a music teacher? Exploring the motivations of pre-service music teachers towards the profession
Authors: Mateos-Moreno Daniel 
Published: December 2023

AbstractUncovering the motivations towards a profession may contribute to a better understanding of how the profession is chosen and will be pursued. However, the research on the attractiveness of the music teaching profession is rather limited and predominantly focused on identity development, thereby overlooking other aspects that may play a role. In pursuing a case study, my aim is to contribute to this field of research by investigating the views of pre-service music teachers enrolled at the University of Karlstad in Sweden. The results depict a unique motivational profile compared to their counterparts in other subjects. These differential aspects are threefold, indicating a high prevalence of ‘extrinsic motivations’ driving their choice of profession, that ‘altruistic reasons’ have lower significance as a motivating factor, and that there is a poor perceived relevance of these individuals’ future profession. In addition, this study provides evidence of the prevalence of ‘musician identities’ over ‘teaching identities’ and foresees the dependence between the participants’ motivation and their future students’ progression. Moreover, I hypothesise that career changes and Pygmalion effects are to be expected if intrinsic motivation towards the profession is not fostered or if this population’s motivation is linked to the progress of their students rather than the challenge of motivating them in the first place.
Differences in the structure of bat assemblages among habitats in the Caatinga dry forest

Published: December 2023

Abstract
The Caatinga is the largest seasonal tropical dry forest with extreme environmental and meteorological conditions. It harbours many phytophysiognomies and vegetational units, but bat fauna is poorly known in many regions. We analysed the structure of bat assemblages by mist-netting during 99 nights in seven habitats throughout six sites in the northeasternmost region of the Caatinga in Rio Grande do Norte State, in the Brazilian northeast. With a sampling effort of 239 665 m2h, we captured 1575 individuals of 31 species of bats. Bat assemblages’ structure and species distribution changed according to the habitat type, and differences in richness, abundance, species composition, and trophic guild representation were found. The frugivore A. planirostris was widespread, and its superabundance hold for all habitats. The distinct array of the most abundant species with several exclusive species in each habitat suggests species- and trophic guild-specific preferences to particular habitats. Differences in the structure of bat assemblages may be driven by each habitat’s vegetational structure and plant composition (e.g., semi-open habitats vs. tall forest stands) that offers distinct exploitable resources (e.g., food and roosts). Finally, we discuss the importance of foraging habitats for the conservation of these unique bat assemblages in the northeasternmost region of the Caatinga dry forest.
An Operational Perspective on the Ethics of the Use of Autonomous Weapons
Authors: Deptula David A. 
Published: December 2023

AbstractRapid technological change is resulting in the development of ever increasingly capable autonomous weapon systems. As they become more sophisticated, the calls for developing restrictions on their use, up to and including their complete prohibition, are growing. Not unlike the call for restrictions on the sale and use of drones, most proposed restrictions are well-intentioned but are often ill-informed, with a high likelihood of degrading national security and putting additional lives at risk. Employed by experienced operators well-versed in the laws of armed conflict, autonomous weapons can advance the objectives of those who would prohibit their use. This essay takes an operational perspective to examine the role that autonomous weapon systems can play while complying with the laws of armed conflict. With responsible design and incorporation of applicable control measures, autonomous weapons will be able not just to comply but also to enhance the ethical use of force. This essay contends that efforts by the international community to use international legal means and/or institutions to over-regulate or even ban lethal autonomous weapons are counterproductive. It considers and describes the end-game results of the use of autonomous weapons in enhancing the application of both international law and human ethical values.
Accountability for the Taking of Human Life with LAWS in War
Authors: Reed Esther D. 
Published: December 2023

AbstractAccountability for developing, deploying, and using any emerging weapons system is affirmed as a guiding principle by the Group of Governmental Experts on Emerging Technologies in the Area of Lethal Autonomous Weapons Systems. Yet advances in emerging technologies present accountability challenges throughout the life cycle of a weapons system. Mindful of a lack of progress at the Convention on Certain Conventional Weapons since 2019, this essay argues for a mechanism capable of imputing accountability when individual agent accountability is exceeded, forensic accountability unreliable, and aspects of political accountability fail.
Mapping the Lethal Autonomous Weapons Debate: An Introduction
Authors: Jackson Josephine 
Published: December 2023

AbstractThe UN Convention on Certain Conventional Weapons (CCW) can, on the one hand, be considered vital for the global governance process—in the sense of urging international cooperation on the ethical, developmental, and standards aspects of lethal autonomous weapon systems (LAWS). On the other hand, the CCW may also embody a global trend that does not augur well for international solidarity, namely the lack of credible and comprehensive collaboration to advance global objectives of peace and security. In 2022, a majority of the 125 nations that belong to the CCW requested limits on a specific type of lethal autonomous weapons: “killer robots.” Yet, most of the major global powers—namely the United States, Russia, and China—opposed not only a ban on LAWS but also on any restrictions on the development of these weapons, not least because the United States, Russia, and China are actively developing this weapons technology. While there is currently much focus on the technological evolution of LAWS, less has been written about how ethical values can exert influence on a growing global consciousness around factors such as power, technology, human judgment, accountability, autonomy, dehumanization, and the use of force. This introduction lays the groundwork for dealing with these issues. It does so by showing that all these factors warrant a pluralist approach to the global governance of LAWS, based on multiple grounds, including the military, tech, law, and distinctive theoretical-ethical orientations; the rationale being to combine this expertise into a collection for publication. Reflecting the contributing authors’ firsthand experiences of the ethics surrounding the management of LAWS to address decisive and critical questions at an expert level, it provides a framing for the collection, showing that the use of international legal mechanisms like the CCW are crucial to considering both the potential and the limits of LAWS, as well as what it can contribute to areas such as international law, human rights, and national security.

Published: December 2023

AbstractAlthough Kawasaki disease is often self-limiting, significant cardiovascular sequelae may occur in the acute or late stage. The most common late complication is persistent coronary artery aneurysm, which can lead to myocardial ischaemia and even myocardial infarction. We report a case of coronary artery bypass grafting in a 16-year-old boy with a history of undiagnosed Kawasaki disease. Increased awareness of Kawasaki disease, especially among children between the ages of 6 months and 5 years, can increase early treatment and prevent serious complications that may occur in the future.
Consumer preferences for produce grown with reduced pesticides: a choice experiment in Missouri
Authors: Tran Lan , McCann Laura , Su Ye 
Published: December 2023

Abstract
There have been growing concerns about exposure to chemical pesticides in fresh fruits and vegetables, which are an important part of a healthy diet. This study investigates consumer preferences for reduced pesticide, organic, local, and Missouri Grown produce using a discrete choice experiment. An online survey of fresh tomato consumers was conducted in Missouri to collect choice data, demographic information, and the individual health and environmental attitudes of shoppers. Respondents were willing to pay a premium of 6% for tomatoes produced with 50% less pesticide than conventional tomatoes. The finding indicates there may be a demand for reduced pesticide produce as a compromise between conventional and organic products in terms of price and safety. Also, we found complementary effects between the reduced pesticide attribute and local or Missouri Grown labels, which means consumers in this segment would pay more for fruits and vegetables that were also locally produced. The results suggest important implications for local producers and policy makers in terms of the production and marketing of reduced pesticide produce, such as the need to develop a reduced pesticide label.
Grit effects on grass weeds and grit-weeding in aronia berry (Aronia melanocarpa)
Authors: Forcella Frank , Dalman Nathan , Poppe Steve , Hoover Emily 
Published: December 2023

Abstract
Two sequential experiments examined the effects of abrasive grit on seedlings of grass weeds and young shoots of perennial weeds. First, four types of grit derived from agricultural residues (bone meal, eggshell, hazelnut shell, and sugar beet pulp) were tested under high air pressure in a controlled environment for their abilities to abrade seedlings of an annual grass, Setaria faberi Herrm., and the perennials Festuca arundinacea Schreb., Poa pratensis L., and Elymus repens (L.) Gould. Differing grit particle sizes and amounts, as well as weed seedling stages, were examined for efficacy after abrasion by each type of grit. Second, hazelnut shell grit was used to control P. pratensis and Taraxicum officinale Weber in field trials with aronia (Aronia melanocarpa [Michx.] Elliott), which is a new, shrubby, berry crop in the midwestern USA. Grit weeding was compared to two other treatments: manual weeding (hand-hoeing + hand-pulling) and no weed control (weedy check) over two years. In the grit comparison experiment, control of S. faberi was highest for egg-shell grit (63–100% across grit particle sizes, rates, and seedling stages) and least for sugar beet pulp (17–97%). The former grit had the highest bulk density of all grits, and the latter had the lowest bulk density. For damage to perennial weeds, egg-shell grit performed best (17–80% control) and bone meal least (10–47% control). Elymus repens was controlled better than other perennial grasses, especially by eggshell grit (up to 73% control) and hazelnut shell grit (up to 67% control) with particle sizes of 1–2 mm. In the aronia experiment, both grit abrasion and manual weeding achieved comparable levels of weed suppression (≥87%) and required similar amounts of cumulative seasonal time spent weeding (3–4 min per shrub). Thus, applications of abrasive grit derived from agricultural residues are potential alternatives for non-chemical management of weeds in aronia and, perhaps, in other high-value perennial crops.
Dominant Drivers for Terrestrial Water Storage Changes Are Different in Northern and Southern China

Published: December 2023

AbstractSubsurface water storage is a key component in the water cycle, and China is facing severe issues with water resource shortage. This study estimates the terrestrial water storage (TWS) changes from 2003 to 2017 using a water balance approach over seven large basins in China. The estimated inter‐annual variations and trends in TWS correspond well with those obtained from the Gravity Recovery and Climate Experiment observation. Variance analysis shows that annual precipitation in northern China plays a more important role in controlling annual TWS variability than that in southern China. This increased sensitivity is primarily attributed to the limited availability of water resources and the arid climate conditions prevalent in northern China. Interestingly, actual evapotranspiration is the dominant driver, contributing more than 55% to the declining trend in TWS in two northern basins: Hai River and Yellow River basins, where the leaf area index has strongly increased. Precipitation and evapotranspiration account for over 89% of the TWS trend over basins in northeastern China. Meanwhile, the dominant drivers for TWS in southern China are precipitation (50%–54%) and runoff (33%–41%). Our results suggest that it requires strong ecological conservation actions in order to keep water resources sustainable in northern China.
