Preservation and Accessibility of the Audiovisual Document of the Trial of the Argentine Military Junta
Authors: Osuna Alarcón Maria R. 
Published: May 2022

AbstractThis research note outlines the current state of preservation and accessibility of an audiovisual document that contains complete video footage of the Trial of the Argentine Military Junta, whose verdict in 1985 found the accused guilty of crimes against humanity perpetrated during the last military dictatorship in Argentina (1976–1983).The project of digitization is the result of a joint effort by the University of Salamanca, the Argentine human rights organization Memoria Abierta, and the judges involved in the case, with the support of the Argentine Cámara Nacional de Apelaciones en lo Criminal y Correccional Federal. Its two main objectives are to preserve and provide open access to the audiovisual document. To date only digitized preservation has been attained, a nonetheless remarkable achievement. Despite legislation dates enforcing the protection of the parties involved in the trial, and the absence of legal constraints, open access to the document has not been obtained.
THE BOUNDARY OF THE p-RANK STRATUM OF THE MODULI SPACE OF CYCLIC COVERS OF THE PROJECTIVE LINE

Published: May 2022

AbstractWe study the p-rank stratification of the moduli space of cyclic degree
$\ell $
covers of the projective line in characteristic p for distinct primes p and
$\ell $
. The main result is about the intersection of the p-rank
$0$
stratum with the boundary of the moduli space of curves. When
$\ell =3$
and
$p \equiv 2 \bmod 3$
is an odd prime, we prove that there exists a smooth trielliptic curve in characteristic p, for every genus g, signature type
$(r,s)$
, and p-rank f satisfying the clear necessary conditions.
Sex Differences in Sexual Desire
Authors: Stegenga Jacob 
Published: May 2022

AbstractThe standard view about sex differences in sexual desire is that males are lusty and loose, while females are cool and coy. This is widely believed and is a core premise of some scientific programs like evolutionary psychology. But is it true? A mountain of evidence seems to support the standard view. Yet, this evidence is shot through with methodological and philosophical problems. Developments in the study of sexual desire suggest that some of these problems can be resolved, and when they are, the standard view looks, at best, to be an exaggeration.

Published: May 2022

AbstractEvaluating synchronies between climate and cultural changes is a prerequisite for addressing the possible effect of environmental changes on human populations. Searching for synchronies during the Middle-Upper Paleolithic transition (ca. 48–36 ka) is hampered by the limits of radiocarbon dating techniques and the large chronological uncertainties affecting the archaeological and paleoclimatic records, as well by their low temporal resolution. Here, we present a high-resolution, pollen-based vegetation record from the Bay of Biscay, sea surface temperature changes, additional14C ages, and a new IRSL date on the fine-sediment fraction of Heinrich Stadial (HS) 6. The IRSL measurements give an age of ca. 54.0 ± 3.4 ka. The paleoclimatic results reveal a succession of rapid climatic changes during the Middle-Upper Paleolithic transition in SW France (i.e. D-O 12–8 and two distinct climatic phases during HS 4). Comparison of the new paleoclimatic record with chronologically well-constrained regional archaeological changes shows that no synchronies exist between cultural transitions and environmental changes. The disappearance of Neanderthals and the arrival ofHomo sapiensin SW France encompassed a long-term forest opening, suggesting thatHomo sapiensmay have progressively replaced Neanderthals from D-O 10 to HS 4 through competition for the same ecological niches.

ABSTRACTA new system for preparing 14C samples was established for a compact accelerator mass spectrometer (GXNU-AMS) at Guangxi Normal University. This sample preparation system consists of three units: a vacuum maintenance unit, a CO2 purification unit, and a CO2 reduction unit, all of which were made of quartz glass. A series of radiocarbon (14C) preparation experiments were conducted to verify the reliability of the system. The recovery rate of graphite obtained was more than 80%. The carbon content in the commercial toner and wood sample was linearly fitted to the CO2 pressure in the measurement unit of the system. The results showed a good linear relationship, indicating that the reliability of the sample preparation system. AMS measurements were conducted on a batch of standard, wood, and dead graphite samples prepared using this system. The results showed that the beam current of 12C- for each sample was more than 40 μA, the carbon contamination introduced during the sample preparation process was ∼ 2 × 10–15, and that the new sample preparation system is compact, low-contamination, and efficient and meets the GXNU-AMS requirements for 14C samples.
EULER–KRONECKER CONSTANTS FOR CYCLOTOMIC FIELDS
Authors: HONG LETONG , ONO KEN , ZHANG SHENGTONG 
Published: May 2022

AbstractThe Euler–Mascheroni constant
$\gamma =0.5772\ldots \!$
is the
$K={\mathbb Q}$
example of an Euler–Kronecker constant
$\gamma _K$
of a number field
$K.$
In this note, we consider the size of the
$\gamma _q=\gamma _{K_q}$
for cyclotomic fields
$K_q:={\mathbb Q}(\zeta _q).$
Assuming the Elliott–Halberstam Conjecture (EH), we prove uniformly in Q that
$$ \begin{align*} \frac{1}{Q}\sum_{Q<q\le 2Q} |{\gamma_q - \log q}| = o(\log Q).\end{align*} $$
In other words, under EH, the
$\gamma _q /\!\log q$
in these ranges converge to the one point distribution at
$1$
. This theorem refines and extends a previous result of Ford, Luca and Moree for prime
$q.$
The proof of this result is a straightforward modification of earlier work of Fouvry under the assumption of EH.
ANAMNÊSISASANEURISKEIN, ANAKINEINANDANALAMBANEININ PLATO'SMENO
Authors: Shepardson Douglas A. 
Published: May 2022

AbstractThis article examines the theory of recollection in Plato'sMenoand attempts to unravel some long-standing puzzles about it. What are the prenatal objects of the soul's vision? What are the post-natal objects of the soul's recollection? What is innate in theMeno? Why does Socrates (prima facie) suggest that both knowledge and true opinion are innate? The article pays particular attention to theana-prefix in the verbsaneuriskô,anakineôandanalambanô, and suggests that they are used for two distinct stages of recollection: a phenomenological stage of ‘finding again’ or ‘awakening’ our innate content, which Plato callsdoxa, and an epistemic stage of ‘getting it back’ asepistêmê.Thinking of the verbs with this ‘back/again’ sense of theana-prefix (instead of as ‘up’, in the common translation ofanalambanôas ‘take up’) allows us to understand why Plato would simultaneously imply that our souls had prenatalepistêmê, have post-natal innate true opinion and have the potential toanalambanein epistêmê. He is not talking about ‘taking up’epistêmêthat he also callsdoxa, but about ‘getting back’ theepistêmêwe had prenatally. The article concludes with an examination of what this innate content is, suggesting that it is a type of ‘principle’ and ‘essential’ mental content.
Continuous versus punctuated vein widening in the Marcellus Formation, USA: the fine line between pressure fringes and hydraulic fractures
Authors: Hooker JN , Cartwright J , Stephenson B , Day CC 
Published: May 2022

AbstractCalcite veins are common in organic-rich mudrocks, but their genesis and ability to transmit fluids are debated. A combined microstructural and isotopic investigation of an array of calcite veins recovered in core from the Marcellus Formation reveals that the veins grew via a combination of continuous fibrous growth and punctuated fracture-opening increments. Continuous opening is the result of pressure-solution creep and involves no mechanical fracturing, but rather the growth of a pressure fringe around a pre-existing, sealed fracture. In contrast, incremental opening is accomplished by overpressured, mineral-saturated fluid, which repeatedly ruptures the rock at the cement / host-rock interface. Punctuated growth increments occurred repeatedly throughout an otherwise protracted, continuous growth history, indicating that the present structures preserve hybrid deformation conditions between brittle, fluid-assisted cracking and plastic strain. Stable isotopic signatures match those of a regional opening-mode fracture set that formed in response to catagenetic fluid overpressures amid a tectonically imposed (Alleghanian) stress field. It is concluded that calcite veins form as opening-mode hydraulic fractures and are susceptible to increments of brittle reactivation, even while inelastic growth processes widen and fill the veins with fibrous cement.
Can cultural values associated with turacos be used to enhance biodiversity conservation in Cameroon?

Published: May 2022

AbstractTuracos are birds used as status symbols in certain African cultures. Despite this cultural value, turacos are increasingly threatened by habitat loss and illegal hunting. We tested the hypothesis that the high cultural value associated with turacos means local people are willing to conserve them and their habitats. To this end, we examined the traditional uses of turacos and how their cultural value could facilitate conservation interventions. We administered an open-ended questionnaire to 180 households during January 2017–November 2019. We found the feathers of three species of turacos to be associated with qualities such as social esteem and power: Bannerman's turaco Tauraco bannermani (categorized as Endangered on the IUCN Red List), green turaco Tauraco persa (Least Concern) and great blue turaco Corythaeola cristata (Least Concern). People were generally supportive of efforts to protect turacos because of a strong connection between these birds and the local culture, supporting our hypothesis. This particularly applied to people of high social standing such as chiefs and village elders who use turaco feathers to gain public distinction. Feathers were also used by herbalists for traditional medicine, and hunters used the birds’ calls as a time indicator. Feathers are generally obtained through opportunistic collection and a sustainable, traditional hunting system, but we also found that some people hunt turacos to sell them as pets. We recommend that conservation interventions make use of the cultural values associated with these iconic species, together with implementing alternative sources of livelihoods, to promote behaviours that help achieve conservation objectives in the area.
Continuity of psychopathology v. resilience across the transition to adolescence: role of hair cortisol and sensitive caregiving

Published: May 2022

AbstractBackgroundThe transition to adolescence implicates heightened vulnerability alongside increased opportunities for resilience. Contexts of early life stress (ELS) exacerbate risk; still, little research addressed biobehavioral mediators of risk and resilience across the adolescent transition following ELS. Utilizing a unique cohort, we tested biosocial moderators of chronicity in adolescents’ internalizing disorders v. resilience.MethodFamilies exposed to chronic war-related trauma, v. controls, were followed. We utilized data from three time-points framing the adolescent transition: late childhood (N = 177, Mage = 9.3 years ± 1.41), early adolescence (N = 111, Mage = 11 0.66 years ± 1.23), and late adolescence (N = 138, Mage = 15.65 years ± 1.31). In late childhood and late adolescence children's internalizing disorders were diagnosed. At early adolescence maternal and child's hair cortisol concentrations (HCC), maternal sensitivity, and mothers’ post-traumatic symptoms evaluated.ResultsWar-exposed children exhibited more internalizing disorders of chronic trajectory and mothers were less sensitive and more symptomatic. Three pathways elucidated the continuity of psychopathology: (a) maternal sensitivity moderated the risk of chronic psychopathology, (b) maternal post-traumatic symptoms mediated continuity of risk, (c) trauma exposure moderated the association between child internalizing disorders at late childhood and maternal HCC, which linked with child HCC. Child HCC linked with maternal post-traumatic symptoms, which were associated with child disorders in late adolescence.ConclusionResults demonstrate the complex interplay of maternal and child's biosocial factors as mediators and moderators of risk chronicity across the adolescent transition following trauma. Findings are first to utilize maternal and child's HCC as biomarkers of chronic stress v. resilience during adolescence, a period of neural reorganization and personal growth that shapes the individual's lifetime adaptation.
The politics of pain: Medicaid expansion, the ACA and the opioid epidemic
Authors: Shepherd Michael E. 
Published: May 2022

AbstractFederalism allows state politicians opportunities to undermine or support for federal policies. As a result, voters often have varied impressions of the same federal programmes. To test how this dynamic affects voting behaviour, I gather data on the severity of the opioid epidemic from 2006–2016. I exploit discontinuities between states that expanded Medicaid and those that did not to gain causal leverage over whether expansion affected the severity of the epidemic and whether these policy effects affected policy feedback. I show that the decision to expand Medicaid reduced the severity of the opioid epidemic. I also show that expanding Medicaid and subsequent reductions in the severity of the opioid epidemic increased support for the Democratic Party. The results imply that the Republican Party performed better in places where voters did not have access to Medicaid expansion and where the epidemic worsened, demonstrating an unintended consequence of federalism on policy feedback.
Profiles of diurnal cortisol and DHEA regulation among children: Associations with maltreatment experiences, symptomatology, and positive adaptation

Published: May 2022

AbstractPerson-centered methods represent an important advance in the simultaneous examination of multiple indicators of neuroendocrine functioning and may facilitate a more nuanced understanding of the impact of child maltreatment on hypothalamic–pituitary–adrenal axis dysregulation. The aims of the present study were threefold: (a) identify naturally occurring patterns of diurnal cortisol and dehydroepiandrosterone (DHEA) regulation among a sample of N = 1,258 children with and without histories of maltreatment, (b) investigate which neuroendocrine profiles characterize children with exposure to maltreatment, and (c) examine which profiles are related to adaptive outcomes and symptomatology among children. Cortisol and DHEA were sampled three times per day (9 a.m., 12 p.m., and 4 p.m.) across 5 and 2 days, respectively. Four profiles of cortisol and DHEA regulation were identified. Among females, a pattern marked by high cortisol and low DHEA was associated with more pervasive maltreatment experiences. Furthermore, we found evidence of adaptive interpersonal resilience such that children with maltreatment exposure who evidenced this pattern of high cortisol and low DHEA were viewed as more likeable than maltreated children with other neuroendocrine patterns. Finally, results pointed to higher levels of internalizing symptoms among children who displayed a profile marked by average cortisol and high DHEA.

AbstractDue to the lack of research between the inner layers in the structure of colonic mucous and the metabolism of fatty acid in the constipation model, we aim to determine the changes in the mucous phenotype of the colonic glycocalyx and the microbial community structure following treatment with Rhubarb extract in our research. The constipation and treatment models are generated using adult male C57BL/6N mice. We perform light microscopy and transmission electron microscopy (TEM) to detect a Muc2-rich inner mucus layer attached to mice colon under different conditions. In addition, 16S rDNA sequencing is performed to examine the intestinal flora. According to TEM images, we demonstrate that Rhubarb can promote mucin secretion and find direct evidence of dendritic structure-linked mucus structures with its assembly into a lamellar network in a pore size distribution in the isolated colon section. Moreover, the diversity of intestinal flora has noticeable changes in constipated mice. The present study characterizes a dendritic structure and persistent cross-links have significant changes accompanied by the alteration of intestinal flora in feces in models of constipation and pretreatment with Rhubarb extract.

Published: May 2022

AbstractDidymos and Dimorphos are primary and secondary, respectively, asteroids who compose a binary system that make up the set of Near Earth Asteroids (NEAs). They are targets of the Double Asteroid Redirection Test (DART), the first test mission dedicated to study of planetary defense, for which the main goal is to measure the changes caused after the secondary body is hit by a kinect impactor. The present work intends to conduct a study, through numerical integrations, on the dynamics of massless particles distributed in the vicinity of the two bodies. An approximate shape for the primary body was considered as a model of mass concentrations (mascons) and the secondary was considered as a massive point. Our results show the location and size of stable regions, and also their lifetime.
Characterization of the stability for trajectories exterior to Jupiter in the restricted three-body problem via closed-form perturbation theory
Authors: Rossi Mattia , Efthymiopoulos Christos 
Published: May 2022

AbstractWe address the question of identifying the long-term (secular) stability regions in the semi-major axis-eccentricity projected phase space of the Sun-Jupiter planar circular restricted three-body problem in the domains i) below the curve of apsis equal to the planet’s orbital radius (ensuring protection from collisions) and ii) above that curve. This last domain contains several Jupiter’s crossing trajectories. We discuss the structure of the numerical stability map in the (a,e) plane in relation to manifold dynamics. We also present a closed-form perturbation theory for particles with non-crossing highly eccentric trajectories exterior to the planet’s trajectory. Starting with a multipole expansion of the barycentric Hamiltonian, our method carries out a sequence of normalizations by Lie series in closed-form and without relegation. We discuss the applicability of the method as a criterion for estimating the boundary of the domain of regular motion.
Oscillations around tidal pseudo-synchronous solutions for circumbinary planets
Authors: Zoppetti F. A. , Folonier H. , Leiva A. M. , Beaugé C. 
Published: May 2022

AbstractTidal evolution of low-eccentric circumbinary planets is expected to drive the rotational evolution toward a pseudo-synchronous solution. In this work, we present a study of the oscillation amplitudes around this state by considering that the two central stars exert creep tides on the planet. These amplitudes are computed by direct numerical integrations of the creep equations and also by means of the calculation of the coefficients of the periodic terms in this stationary solution. As in the two-body-problem, the planetary spin and lag-angle are observed to have maximum oscillation amplitudes for stiff bodies and almost null oscillation for the gaseous regime, while the opposite behaviour is observed in the equatorial and polar flattenings. Our analytical approximation shows to be very accurate and specially necessary for very-low eccentric planets. However, the magnitudes of the oscillation amplitudes around the pseudo-synchronous solution in the circumbinary problem appears to be very small respect to the mean value. Thus, considering these oscillation in the computation of the tidal energy dissipation may not have a substantial contribution in the results, at least compared to the case in which only the mean values are taken into account.

AbstractWe have studied the probabilistic evolution of four candidates for young pairs of trans-Neptunian objects: 2003 QL91 – 2015 VA173, 1999 HV11 – 2015 VF172, 2002 CY154 – 2005 EW318 and 2013 SD101 – 2015 VY170 over 10 Myr in the past. All pairs belong to cold Classical Kuiper Belt objects. We concluded that the age of the considered pairs exceeds 10 Myr.
Closed-form perturbation theory in the Sun-Jupiter restricted three body problem without relegation
Authors: Cavallari Irene , Efthymiopoulos Christos 
Published: May 2022

AbstractWe present a closed-form normalization method suitable for the study of the secular dynamics of small bodies inside the trajectory of Jupiter. The method is based on a convenient use of a book-keeping parameter introduced not only in the Lie series organization but also in the Poisson bracket structure employed in all perturbative steps. In particular, we show how the above scheme leads to a redefinition of the remainder of the normal form at every step of the formal solution of the homological equation. An application is given for the semi-analytical representation of the orbits of main belt asteroids.
