Evaluating the Influence of Gravity on Shoulder Strength Measures Assessed via Handheld Dynamometry
Authors: Dixon Edmond J. , Sánchez De La Cruz Christian R. , Artese Ashley L. 
Published: May 2022

Context: Handheld dynamometry is a feasible, reliable, and cost-effective method for assessing shoulder strength. One limitation to this tool is the lack of standardized testing protocols and specified shoulder strength test positions. Although it is recommended that strength tests be performed in a gravity-eliminated position, this may not always be a feasible or practical testing protocol. There is limited research on the influence of gravity on strength measures; to our knowledge, no study has compared handheld dynamometry shoulder strength assessments based on body position and gravity. Therefore, the purpose of this study was to compare shoulder flexion, extension, and abduction strength assessed via handheld dynamometry between a gravity-eliminated and a gravity-influenced test position. Design: This study was a comparison of shoulder strength based on test position. The test position was the independent variable, and the dependent variables were shoulder flexion, extension, and abduction strength. Methods: Supine (gravity-eliminated) and seated (gravity-influenced) strength measures were assessed in 20 healthy adults (19.4 [1.2] y) on the dominant arm. Paired t tests were used to determine differences between body positions for each test. Significance was accepted at P ≤ .05. Results: There were no differences between supine and seated flexion and extension measures. Absolute supine shoulder abduction scores (152.5 [58.4] N) were significantly higher than seated scores (139.9 [55.6] N). Conclusions: Findings show that gravity should be considered when using handheld dynamometry scores as indicators of abductor shoulder strength and function.
The optical theorem in action: radiation of an electron in a Lorentz-violating vacuum
Authors: Borisov Anatoly V. 
Published: May 2022

AbstractAccording to the optical theorem, the imaginary part of the one-loop radiative shift of the electron energy in an external field (IP1L) determines the total probability of photon emission by the electron. We calculate IP1L and then the probability and power of radiation of an electron in a constant background tensor field, which simulates the violation of Lorentz invariance in the framework of the Standard Model Extension. Using current experimental constraints on the background field strength, we show that the considered radiation effect can manifest itself under astrophysical conditions at ultrahigh electron energy.
Holographic spacetime, black holes and quantum error correcting codes: a review
Authors: Kibe Tanay , Mandayam Prabha , Mukhopadhyay Ayan 
Published: May 2022

AbstractThis article reviews the progress in our understanding of the reconstruction of the bulk spacetime in the holographic correspondence from the dual field theory including an account of how these developments have led to the reproduction of the Page curve of the Hawking radiation from black holes. We review quantum error correction and relevant recovery maps with toy examples based on tensor networks, and discuss how it provides the desired framework for bulk reconstruction in which apparent inconsistencies with properties of the operator algebra in the dual field theory are naturally resolved. The importance of understanding the modular flow in the dual field theory has been emphasized. We discuss how the state-dependence of reconstruction of black hole microstates can be formulated in the framework of quantum error correction with inputs from extremal surfaces along with a quantification of the complexity of encoding of bulk operators. Finally, we motivate and discuss a class of tractable microstate models of black holes which can illuminate how the black hole complementarity principle can emerge operationally without encountering information paradoxes, and provide new insights into generation of desirable features of encoding into the Hawking radiation.
Ultrahigh-energy gamma rays and gravitational waves from primordial exotic stellar bubbles
Authors: Cai Yi-Fu , Chen Chao , Ding Qianhang , Wang Yi 
Published: May 2022

AbstractWe put forward a novel class of exotic celestial objects that can be produced through phase transitions occurring in the primordial Universe. These objects appear as bubbles of stellar size and can be dominated by primordial black holes (PBHs). We report that, due to the processes of Hawking radiation and binary evolution of PBHs inside these stellar bubbles, both electromagnetic and gravitational radiations can be emitted that are featured on the gamma-ray spectra and stochastic gravitational waves (GWs). Our results reveal that, depending on the mass distribution, the exotic stellar bubbles consisting of PBHs not only provide a decent fit for the ultrahigh-energy gamma-ray spectrum reported by the recent LHAASO experiment, but also predict GW signals that are expected to be tested by the forthcoming GW surveys.
Neutrino tagging: a new tool for accelerator based neutrino experiments
Authors: Perrin-Terrin Mathieu 
Published: May 2022

AbstractThis article describes a new experimental method for accelerator based neutrino experiments called neutrino tagging. The method consists in exploiting the neutrino production mechanism, the "Equation missing" decay, to kinematically reconstruct the neutrino properties from the decay incoming and outgoing charged particles. The reconstruction of these particles relies on the recent progress and on-going developments in silicon particle detector technology. A detailed description of the method and achievable key performances is presented, together with its potential benefits for short and long baseline experiments. Then, a novel configuration for long baseline experiments is discussed in which a tagged beam would be employed together with mega-ton scale natural deep water Cherenkov detectors. The coarseness of this type of detectors is overcome by the precision of the tagging and, conversely, the rate limitation imposed by the tagging is outweighed by the size of the detector. These mutual benefits result in an affordable design for next generations of long baseline experiments. The physics potential of such experiments is quantified using the Protvino to KM3NeT/ORCA setup as a case study for which an unprecedented sensitivity to the leptonic CP violation could be achieved.
Neutrino tomography of the Earth with ORCA detector
Authors: Capozzi F. , Petcov S. T. 
Published: May 2022

AbstractUsing PREM as a reference model for the Earth density distribution we investigate the sensitivity of ORCA detector to deviations of the Earth (i) outer core (OC) density, (ii) inner core (IC) density, (iii) total core density, and (iv) mantle density, from their respective PREM densities. The analysis is performed by studying the effects of the Earth matter on the oscillations of atmospheric$$\nu _{\mu }$$νμ,$$\nu _e$$νe,$${\bar{\nu }}_\mu $$ν¯μand$${\bar{\nu }}_e$$ν¯e. We present results which illustrate the dependence of the ORCA sensitivity to the OC, IC, core and mantle densities on the type of systematic uncertainties used in the analysis, on the value of the atmospheric neutrino mixing angle$$\theta _{23}$$θ23, on whether the Earth mass constraint is implemented or not, and on the way it is implemented, and on the type – with normal ordering (NO) or inverted ordering (IO) – of the light neutrino mass spectrum. We show, in particular, that in the “most favorable” NO case of implemented Earth mass constraint, “minimal” systematic errors and$$\sin ^2\theta _{23}=0.58$$sin2θ23=0.58, ORCA can determine, e.g., the OC (mantle) density at$$3\sigma $$3σC.L. after 10 years of operation with an uncertainty of (− 18%)/+ 15% (of (− 6%)/+ 8%). In the “most disfavorable” NO case of “conservative” systematic errors and$$\sin ^2\theta _{23}=0.42$$sin2θ23=0.42, the uncertainty on OC (mantle) density reads (− 43%)/+ 39% ((− 17%/+ 20%), while for for$$\sin ^2\theta _{23} = 0.50$$sin2θ23=0.50and 0.58 it is noticeably smaller: (− 37)%/+ 30% and (− 30%)/+ 24% ((− 13%)/+ 16% and (− 11%/+ 14%)). We find also that the sensitivity of ORCA to the OC, core and mantle densities is significantly worse for IO neutrino mass spectrum.
Automated, Cost-effective, and Update-driven App Testing
Authors: Ngo Chanh Duc , Pastore Fabrizio , Briand Lionel 
Published: May 2022

Apps’ pervasive role in our society led to the definition of test automation approaches to ensure their dependability. However, state-of-the-art approaches tend to generate large numbers of test inputs and are unlikely to achieve more than 50% method coverage.
In this article, we propose a strategy to achieve significantly higher coverage of the code affected by updates with a much smaller number of test inputs, thus alleviating the test oracle problem.
More specifically, we present ATUA, a model-based approach that synthesizes App models with static analysis, integrates a dynamically refined state abstraction function and combines complementary testing strategies, including (1) coverage of the model structure, (2) coverage of the App code, (3) random exploration, and (4) coverage of dependencies identified through information retrieval. Its model-based strategy enables ATUA to generate a small set of inputs that exercise only the code affected by the updates. In turn, this makes common test oracle solutions more cost-effective, as they tend to involve human effort.
A large empirical evaluation, conducted with 72 App versions belonging to nine popular Android Apps, has shown that ATUA is more effective and less effort-intensive than state-of-the-art approaches when testing App updates.
COVID-19 Crisis, Economic Hardships, and Schooling Outcomes
Authors: Gehrke Esther , Lenel Friederike , Schupp Claudia 
Published: May 2022

AbstractWe combine phone-survey data from 2,200 students collected in July–August of 2020 with student-level administrative data from 54 schools in four northwestern provinces of Cambodia to investigate the implications of the COVID-19 pandemic for grade 9 students. These students were particularly vulnerable to dropping out of school prematurely due to the crisis. We find that most students kept studying during the crisis, returned to school to participate in the lower-secondary graduation exam after schools reopened, and transitioned to high school thereafter. However, we also find that students' exposure to the economic downturn had substantial implications: The likelihood that the father experienced income losses due to the crisis is negatively associated with a student's propensity to study during school closure, participation and performance in the final exam, and with the likelihood to transition to high school. In contrast, the likelihood that the mother experienced income losses is positively associated with student studying during the crisis, with participation in the final exam, and with transition to high school—potentially because mothers used the time at home to encourage their children to study.
Leveraging Experimental and Observational Evidence to Assess the Generalizability of the Effects of Early Colleges in North Carolina
Authors: Fuller Sarah , Lauen Douglas Lee , Unlu Fatih 
Published: May 2022

Abstract
Early college high schools (ECHSs) in North Carolina are small public schools of choice on college campuses that seek to promote attaining postsecondary credits in high school, college readiness, and postsecondary enrollment for underrepresented groups. Evidence from randomized control trials (RCTs) has shown positive effects of the ECHS model on important high school and postsecondary outcomes but appear to be underpowered to detect moderation effects. Furthermore, RCTs rarely address the key question of primary policy interest: Is the program effective on average across the population? This leaves us uncertain about (1) whether the early college intervention is a good strategy for helping to close enrollment and attainment gaps between under- and overrepresented groups, and (2) whether the expansion of the ECHS model will lead to the positive results that the RCT studies suggest. This study uses administrative data on all ECHSs in North Carolina including those that were part of a lottery study. This allows us to generate RCT estimates for the ECHSs in the lottery sample and quasi-experimental estimates for both the lottery and non-lottery ECHSs. We leverage this unique circumstance to generate estimates of the effect of ECHS on postsecondary outcomes that simultaneously maximize both internal and external validity. Specifically, because generalization depends on both moderation and sample selection, we (1) investigate sample selection, (2) conduct a moderation analysis to determine whether the effects of the intervention vary by key factors that also predict sample selection, and (3) produce a pooled estimate by extending a method called cross-design synthesis to incorporate both RCT evidence and quasi-experimental evidence. We find strong evidence that the positive results of the RCTs generalize to the full sample of ECHSs, which provides stronger evidence of effectiveness.
Mystery Cult in Vergil
Authors: Mac Góráin Fiachra , Nelis Damien 
Published: May 2022

Abstract
In this paper we begin with a brief survey of the presence of the mysteries in Greek and Latin epic poetry, before giving an overview of the mysteries in Vergil and attempting to identify the function of the references to mystery religion in Aeneid 6. Throughout, we consider the modality of how the poets allude to the mysteries in ways that allow mystery cults to take on a life of their own in imaginative literary representations, arriving at the conclusion that it is only by means of closer collaboration between literary critics and historians of religion that progress will be made in this complex field of study.
Uncivilized Behaviors: How Humans Wield “Feral” to Assert Power (and Control) over Other Species
Authors: Hill Kristine , Szydlowski Michelle , Heaney Sarah Oxley , Busby Debbie 
Published: May 2022

Abstract
This paper examines the use of the term “feral” as a form of control over other animals. The concept of this “power word” is explored within the context of what it means for those who find themselves labelled as such. As a prefix, “feral” is used by various interest groups to justify the treatment of subpopulations of species, particularly with regards to wildlife conservation. The “feral” label differentiates animals that are perceived as being out of place or out of control from those who are kept as companions or commodities. “Feral” is most often used to describe an unwelcome presence or noise, and can be contrasted to alternative words, such as “wild” or “free-living” that control how these presences are perceived by humans.
Rare genetic admixture and unidirectional gene flow between Vipera aspis and Vipera berus at their contact zone in western France
Authors: Zwahlen Valerie , Lourdais Olivier , Ursenbacher Sylvain , Guiller Gaëtan 
Published: May 2022

Abstract
Asp vipers (Vipera aspis) and adders (Vipera berus) coexist in the Loire-Atlantique department in France where the two species reach their respective range limits. This contact zone is of special interest since hybridization has been recently discovered there. We carried out extensive sampling to further investigate the hybrid status of morphologically typical individuals and to evaluate the proportion of genetically admixed individuals in this area. Using microsatellite markers, no hybrids with typical morphological traits of either asp vipers or adders were detected. All recently investigated individuals with intermediate morphological traits were shown to be hybrids. A rather low proportion of genetically admixed individuals (1.5-3%) and a very small number of supposed second-generation hybrids suggest reduced fertility of first-generation hybrids or low viability of their progeny. The investigation of mtDNA of newly sampled hybrids support the finding that hybridization only occurs between female V. aspis and male V. berus. Several possible explanations for the unidirectional hybridization are discussed and consequent future studies suggested.

Published: May 2022

Summary
The nematode causing the green stem and foliar retention syndrome of soybean, Aphelenchoides besseyi, is a concern to Brazilian growers, especially in warm and humid climates, where losses can reach 60% of the yields. Management options have not yet been studied properly, but apparently genetic variability is found in soybean genotypes in the resistance to this nematode. However, the correct phenotyping of soybean genotypes is compromised by the scarcity of studies of this pathosystem. Therefore, the objective of this study was to evaluate the inoculum densities of A. besseyi and the plant ages at inoculation to obtain the correct phenotyping of soybean genotypes. Experiments were conducted under glasshouse conditions with the soybean ‘Elite’, using a completely randomised design and a factorial scheme (five nematode population densities: 150, 300, 600, 1200 and 2400 nematodes plant−1, and three plant ages at inoculation: 7, 12 and 17 days after planting). Evaluations were performed 35 days after inoculation, extracting nematodes from soil, roots and shoot parts of plants to obtain the final population of the nematodes of each replicate. The inoculum of 150-300 A. besseyi specimens per plant is the most suitable to assess the reaction of soybean genotypes to this nematode as it resulted in the greatest reproduction factors. Population densities higher than 1500 nematodes per plant could lead to misclassification of the host reaction because of the inconsistent reproduction factors obtained.
Does Justin Argue with Jews? Reconsidering the Relevance of Philo
Authors: Hubbard Jeffrey M. 
Published: May 2022

Abstract
Several recent studies on Justin’s Dialogue with Trypho the Jew have argued that the Dialogue should not be read as a witness to the state of theological debate between Jews and Christ-followers in the second century. Such arguments conclude that Justin does not engage with actual Jewish perspectives, but rather reconstructs a hypothetical Judaism from second-hand, polemical sources, or merely uses Trypho’s “Judaism” as a stand-in for what are actually (in Justin’s view) heterodox Christian interpretations. This article challenges this claim by returning to an older debate in Justin scholarship: the question of his relationship with Philo of Alexandria. By attending particularly to the role of the Logos in each author’s exegesis of Pentateuchal theophanic texts, the article argues that Justin’s interpretations in the Dialogue carefully avoid a kind of Logos theology that is well represented in the writings of Philo. This rhetorical distancing supports the conclusion that, in the Dialogue, Justin is in fact responding to exegetical traditions which he knows from the writings of Hellenized Judaism.
The Sound of Silence: Augustine’s Soundscape for the Christian Empire
Authors: Abbott Philip 
Published: May 2022

Abstract
Ancient philosophers sought to tune the soul and society to the musica universalis, the celestial harmony generated by the rational wheelworks of the cosmos. For Romans, this overarching rationality was associated with the rational speech of elite masculinity. Augustine subverts this discourse, however. Maintaining that the musica universalis is tuned to the love of God rather than rationality, Augustine depicts Roman history as chaotic dissonance that is out of tune with cosmic harmony. He effects a cosmic key change which idealizes behavior that Roman elites would have viewed absurd. Instead of selling a traditional type of speech (rhetoric) that according to Augustine leads to chaos, he teaches Christians to embrace activities in which the uneducated can participate – singing Psalms, and bursting into sudden, incomprehensible eruptions of divine joy, which he terms jubilus. In short, Augustine preaches a radically new sonority to undergird a new society.
Punishment, Legality, and Other Challenges of International Criminal Law
Authors: Carlson Kerstin Bree 
Published: May 2022

Abstract
Although international criminal law has developed significantly in the 75 years following the Nuremberg Tribunals, the challenge to the legality principle at the heart of its practice remains unaddressed. This article discusses the structural challenges to international criminal law’s legitimacy, beginning by deconstructing the progress paradox that simultaneously legitimizes and undermines international criminal law. Because these challenges are situated in questions of how actions are legally characterized at international criminal law, the article moves on to consider two recent icc cases that demonstrate two aspects of this fundamental challenge to international criminal law practice at work. These cases, the article argues, demonstrate the doctrinal problems that arise from a legal form that bases its legitimacy on its promise of progress.
‘One’s Own’ in the Other and the Other in ‘One’s Own’
Authors: Trächtler Jasmin 
Published: May 2022

Abstract
The questions of how we can understand others and how we can know what they feel, think and sense have repeatedly preoccupied Wittgenstein since the 1930s and especially in his last writings. In this article, the author will tackle these questions by focusing on the other as other or strange. For it is also the strangeness of others, their otherness as such, that makes it difficult and even impossible to recognize and understand their inner life. As she will show, such otherness can be made comprehensible by fictional narratives, in which aspects of others’ lives are related to what is one’s own, i.e., our own inner experience, such that we can find ourselves in them. Moreover, she will argue that this idea of making something comprehensible through fictional narratives has a special methodological relevance for Wittgenstein when it comes to understanding what is ‘one’s own’ in the broadest sense.
Coming out of your shell or crawling back in: multiple interphylum host switching events within a clade of bivalve- and ascidian-associated shrimps (Caridea: Palaemonidae)
Authors: de Gier Werner , Groenhof Mike , Fransen Charles H.J.M. 
Published: May 2022

Abstract
Marine symbiotic Palaemonidae, comprising over 600 species, live in association with marine invertebrates of different phyla, like Cnidaria, Echinodermata, Mollusca, Porifera, and Tunicata. A phylogenetic study is performed on a clade of bivalve- and ascidian-associated endosymbiotic shrimp species (Caridea: Palaemonidae), using morphological and molecular data. A Total Evidence approach is used in order to include all currently known ingroup species in an evolutionary framework. Ancestral state reconstruction analyses are performed to identify host-switching events and ancestral ranges. The clade, including Ascidonia, Conchodytes, Dactylonia, Odontonia, and Pontonia, and various smaller genera, is recovered as monophyletic, with an ascidian-associated ancestral host state. At least six interphylum host switches are tentatively identified, with members of Odontonia and Notopontonia switching back to an ascidian host affiliation after the ancestral host switch of the clade including Conchodytes, Odontonia and related genera, from an ascidian- to a bivalve host. The clade including Ascidonia and Pontonia was recovered to have an ancestor with an East Pacific/Atlantic distribution. The other studied genera remained in the original ancestral Indo-West Pacific range. We hypothesize that similar internal environments of shrimp hosts from different phyla will function as hot spots for interphylum host switching in various lineages of symbionts.
