Revolutionary electricity in 1790: shock, consensus, and the birth of a political metaphor
Authors: Wesner Samantha 
Published: July 2021

AbstractThe 1790 Fête de la fédération in the early French Revolution evoked the memory of the taking of the Bastille while tamping down on the simmering social forces that had erupted on 14 July 1789. How to do both? As an official architect put it, through the festival, ‘the sentiment of each becomes the sentiment of all by a kind of electrification, against which even the most perverse men cannot defend themselves’. This paper argues that a new language of revolutionary electricity came into being with the French Revolution. It argues that revolutionaries drew upon concepts of medical electricity developed in the 1780s to analogize the literal electricity of the ether to the revolutionary electricity of collective political sentiment. Though historians have associated electricity with radical politics, this paper argues that in the hands of bureaucrats and festival planners, electricity entered revolutionary discourse as a powerful mechanism for exercising authority and control over an unruly revolutionary public.
The effect of retirement on the health of elderly people: evidence from China
Authors: Wang Zengwen , Chen Yaofeng , Chen Yucheng 
Published: July 2021

AbstractThe low retirement age has imposed a heavy economic burden on the pension system in China, leading to an ongoing debate about raising the retirement age. To understand the potential costs of raising the retirement age, we need to consider the health effects of retirement policies. Using the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2015, this study employs the statutory retirement age as the exogenous variable of retirement and applies a fuzzy regression discontinuity design (RDD) to examine the effect of retirement on the health of Chinese elderly people. We find that retirement has a non-significant effect on health with respect to a series of health indicators, different bandwidths of RDD and sub-sample groups. The finding is also robust across different retirement definitions and retirement ages. This result may be attributed to the minimal changes in income and lifestyles before and after retirement. Moreover, the findings of this study provide important evidence for policy makers to increase retirement ages in China.
Child abuse and automatic emotion regulation in children and adolescents

Published: July 2021

AbstractChild abuse is associated with elevated risk for psychopathology. The current study examined the role of automatic emotion regulation as a potential mechanism linking child abuse with internalizing psychopathology. A sample of 237 youth aged 8–16 years and their caregivers participated. Child abuse severity was assessed by self-report questionnaires, and automatic emotion regulation was assessed using an emotional Stroop task designed to measure adaptation to emotional conflict. A similar task without emotional stimuli was also administered to evaluate whether abuse was uniquely associated with emotion regulation, but not cognitive control applied in a nonemotional context. Internalizing psychopathology was assessed concurrently and at a 2-year longitudinal follow-up. Child abuse severity was associated with lower emotional conflict adaptation but was unrelated to cognitive control. Specifically, the severity of emotional and physical abuse, but not sexual abuse, were associated with lower emotional conflict adaptation. Emotional conflict adaptation was not associated with internalizing psychopathology prospectively. These findings suggest that childhood emotional and physical abuse, in particular, may influence automatic forms of emotion regulation. Future work exploring the socioemotional consequences of altered automatic emotion regulation among youth exposed to child abuse is clearly needed.
Osmo-priming in tomato seeds down-regulates genes associated with stress response and leads to reduction in longevity

Published: July 2021

AbstractTomato seeds subjected to osmo-priming show fast and more uniform germination. However, osmo-priming reduces seed longevity, which is a complex seed physiological attribute influenced by several mechanisms, including response to stress. Thus, to have new insights as to why osmo-primed tomato seeds show a short life span, we performed a transcript analysis during their priming. For that, we performed gene expression studies of the heat-shock protein family genes that were previously reported to be associated with the enhancement of longevity in primed tomato seeds. Physiological assays of germination, vigour and longevity tests were used to support the data. The results show that the short life span of osmo-primed tomato seeds is related to the decrease in the expression of transcripts associated with response to stress during the priming treatment. These results are important because they add information regarding which seed longevity mechanisms are impacted by the priming treatment. In parallel, it will allow the use of these genes as markers to monitor longevity in osmo-primed tomato seeds.

Published: July 2021

ABSTRACTCoronary artery fistulas have been described in patients after heart transplantation more often than in the normal population. We reviewed our centre’s database between 2008 and 2020. Thirty patients had coronary angiography and 13 showed non-cameral coronary artery fistulas in their first coronary angiography. Distribution, degree and evolution of the fistulas and characteristics of transplant procedure, patient and immunosuppressive treatments were analysed.
Debating the embolization of a large aberrant systemic artery for pulmonary sequestration using an Amplatzer duct occluder: a case report and literature review
Authors: Zhang Yulin , Qiu Yu , Li Yifei 
Published: July 2021

AbstractHere, we report two rare cases of pulmonary sequestration that were fed by large systemic arteries and embolized with a large Amplatzer duct occluder and their 3-year follow-up, and we discuss the efficacy and safety of the embolization of a large aberrant systemic artery to pulmonary sequestration using an Amplatzer duct occluder. A 9-year-old boy complained of chest pain for 1 month, and a 6-year-old boy initially complained of recurrent cough for 3 months. A series of examinations was launched to evaluate any possible malformation or abnormalities in the patients. Chest CT and CTA identified a right lower pulmonary sequestration with infection. After admission, transcatheter device occlusion was planned after essential antibiotic treatment, and postoperative infection prevention and anti-inflammatory treatment were given. In the following 2 years of follow-up, neither of the children had recurrent chest pain, cough or other related symptoms. However, the CT follow-up demonstrated that a residual mass was visible in both patients. The same chest scan section revealed slight reductions in lung lesions from 38.344 cm2to 37.119 cm2(3% reduction) and 14.243 cm2to 13.178 cm2(7.5% reduction) for each patient. No follow-up data demonstrated the long-term clinical outcomes of the residual lesion. We do not recommend that embolization be performed for large pulmonary sequestration lesions with an aberrant artery larger than 6 mm that is planned to receive a device larger than 10 mm, as their outcomes showed a higher possibility of rebuilding the vascularization network feeding the pulmonary sequestration, indicating a higher risk for long-term complications.
Serum pyridoxine, folate, cobalamin, and homocysteine levels in children presenting with vasovagal syncope
Authors: Kovalchuk Tetiana , Boyarchuk Oksana 
Published: July 2021

AbstractBackground:Recent studies confirm the role of B vitamins deficiency and hyperhomocysteinaemia in the development of dysautonomia that has been considered to be the main factor in vasovagal syncope development. The aim of the study was to investigate serum pyridoxine, folate, cobalamin, and homocysteine levels in children presenting with vasovagal syncope and to analyse the correlation between them and main clinical parameters of syncope.Methods:We studied 40 children, ages 8–17 years with a history of vasovagal syncope and 24 healthy volunteers. The serum pyridoxine, folate, cobalamin, and homocysteine levels were measured by a quantitative sandwich enzyme immunoassay technique using a commercial kit (Monobind, USA). Twenty-four-hour Holter monitoring and 24-hour ambulatory blood pressure monitoring were conducted for all participated patients.Results:Serum pyridoxine (9.42 ± 4.87, 16.11 ± 5.53 µg/L) and cobalamin (307.48 ± 95.50, 447.28 ± 108.85 ng/L) levels were reasonably low (p < 0.05) in patients with vasovagal syncope. Although there was no significant change in folate levels between syncope and healthy children (4.00 ± 1.34, 4.71 ± 1.73 µg/L; p = 0.20), we detected low folate-level association with longer duration of syncope (r = −0.42) and post syncope (r = −0.43) symptoms (p < 0.05). Finally, there was increased serum homocysteine level (13.55 ± 5.03, 7.81 ± 1.71 µmol/L; p < 0.05) in patients with vasovagal syncope. It was positively correlated with the average PQ interval (r = 0.35, p < 0.05) and average QTc interval (r = 0.49, p < 0.05).Conclusions:The results suggested that pyridoxine, folate, cobalamin, and homocysteine may be involved in the pathogenesis of vasovagal syncope. This might provide a new approach for effective treatment of paediatric vasovagal syncope, requiring further study.

Published: July 2021

AbstractObjective:As part of an update of feeding benchmarks targeting children aged 0–3 years, this study aimed to explore parental perceptions, information-seeking practices and needs concerning infant and young child feeding (IYCF) to design an efficient communication strategy.Design:Participants were recruited using the quota sampling to complete an online survey. Effects of parity, child age, prematurity, parental education and financial situation on parents’ responses were evaluated separately.Setting:France.Participants:A nationally representative sample of 1001 parents of children <4 years.Results:Parents whose child had any medical condition affecting feeding (children with medical condition (CMC), 17 %) were considered separately from healthy children’s parents. All the healthy children’s parents recognised the importance of IYCF for children’s health and growth; however, one-third considered the available advice contradictory and not guilt-free. The most used information sources were healthcare professionals (HCP, 81 %), internet (72 %) and parental networks (63 %). The most influential sources (mean influence ± sd) included HCP (7·7 ± 1·7/10), childcare professionals (7·3 ± 1·8/10) and parental networks (6·9 ± 1·8/10). Parents searched for practical tips for implementing IYCF starting when their child was 5 months old. Differences regarding the type of source used by parents with higher v. lower educations were small. Search strategies differed according to parity or child age but not to prematurity. The CMC parents reported slightly different practices and needs.Conclusions:Parents receive information from multiple sources, which can lead to confusion when deciding which advice to follow. A public health communication strategy adapted to the current parental needs should target these various sources.

Published: July 2021

Zusammenfassung. Studieren stellt hohe Anforderungen an selbstregulatorische Fähigkeiten und eigenverantwortlichen Umgang mit schwierigen Situationen. Aus den zusätzlichen sprachlichen Barrieren für ausländische Studierende erwachsen spezifische selbstregulatorische Aufgaben, wie der Umgang mit Verständnisproblemen in Vorlesungen. Da hierfür bisher kaum geeignete Erhebungsinstrumente existieren, versucht ScenEx diese Lücke zu schließen. Der Test erfasst das metakognitive Strategiewissen in sprachlich herausfordernden Situationen im Studienalltag. Anhand einer Stichprobe von 290 ausländischen Studierenden im ersten Fachsemester wird die psychometrische Qualität und interne Struktur des Instruments überprüft. ScenEx zeigt eine zufriedenstellende interne Konsistenz und gute Itemfit-Kennwerte, erwartungskonform liegen lokale stochastische Abhängigkeiten der Aufgaben innerhalb der Szenarien vor. Eine konfirmatorische Faktorenanalyse bestätigt die Grobstruktur der Szenarien und des Gesamtscores des Tests. Das Verfahren ist für die weitere Entwicklung der Sprachkompetenz über die anfängliche Sprachfähigkeit hinaus prädiktiv. ScenEx erweist sich insgesamt als ein reliables und valides Instrument zur Erfassung des Strategiewissens in schwierigen Situationen im Studium.
A Variational Principle for the Integrated Channels and Slopes of Stable Equilibrium Landscapes
Authors: Smith Terence R. 
Published: July 2021

AbstractThe equations and constraints of a general class of models of equilibrium fluvial landscapes are represented as a variational principle (VP). The VP minimizes a functional defined as the sum of (a) the difference between the total kinetic and potential energies of flows over the unchanneled slopes and (b) the sum of the kinetic and potential energies of the channelized flows. When the flows over the slopes are subject to a stability constraint on their magnitude, landscapes that minimize the functional are characterized by: (a) the occurrence on channel boundaries of the minimally stable value of slope runoff; (b) the symmetry of inflows into the channels; (c) the minimal total channel length for rainfall and area ; (d) the minimization of the action of the slopes if and only if they are stable and their slope‐discharge relation is monotone‐increasing in slope; and (e) the minimization of channel energy if and only if the slope‐discharge relation for channels is monotone‐decreasing in slope. Applications of the variational theory to first order channels on a linear ridge lead easily to solutions with equal‐length, uniformly‐spaced channels in symmetrical valleys staggered at the ridge‐crests. These solutions minimize the functional of the VP when the equilibrium landscape is in a minimally‐stable state and correspond well to numerical solutions to analogous time‐dependent models driven to equilbrium. The theory offers a promising approach for investigating the structure of equilibrium channel networks that are stably integrated into equilibrium slopes.

AbstractWe have revisited the well‐trod VM28‐122 core retrieved from the deep Colombian Basin, which includes sediments that reflect modern Upper North Atlantic Deep Water and extends through the last deglaciation into the last glacial period when the site was bathed in Glacial North Atlantic Intermediate Water. Here, we leverage the nearby Cariaco Basin's surface water radiocarbon reconstruction (reservoir age, and ΔR) on the IntCal20 timescale to recast the period of the last deglaciation with a newly constrained age model. Based on the revised age model, we observe that the multimillennial decrease in benthic δ13C and B/Ca (which record δ13C of dissolved inorganic carbon and Δ[CO3−2], respectively) began at 18,100 ± 240 (95% CI) calibrated years BP, synchronous with Termination 1, as identified by changes in the Antarctic Ice Sheet composite and by the onset of rapid glacier recession in the Southern Hemisphere (Denton et al., 2010, https://doi.org/10.1126/science.1184119; Denton et al., 2021, https://10.1016/j.quascirev.2020.106771). The beginning of the decrease in benthic δ18O is concurrent with the changes in carbon chemistry or at most, a few hundred years later. It is no later than 17,700 ± 300 (95% CI) yrs BP in our record, at the putative start of Heinrich Stadial 1. With sufficient data density (more than 2–3 control points per kyr) and an independent record of past surface water radiocarbon variations, it is possible to achieve late glacial and deglacial chronologies with fidelities similar to those of ice cores. Doing so in more oceanographic locations should shed light more broadly on the mechanisms instrumental to abrupt climate change.

AbstractA significant amount of the ongoing shortening between the Eurasian and Arabian plates is accommodated within the Zagros Fold‐Thrust Belt. However, the spatial and temporal distribution of active shortening within the belt, especially in its NW part, is not yet well constrained. We determined depositional ages of uplifted river terraces crossing the belt along the Greater Zab River using luminescence dating. Kinematic modeling of the fault‐related fold belt was then used to calculate long‐term slip rates during the Late Pleistocene to Holocene. Our results provide new insight into the rates of active faulting and folding in the area. The Zagros Mountain Front Fault accommodates about 1.46 ± 0.60 mm a−1 of slip, while a more external basement fault further to the SW accommodates less than 0.41 ± 0.16 mm a−1. Horizontal slip rates related to detachment folding of two anticlines within the Zagros Foothills are 0.40 ± 0.10 and 1.24 ± 0.36 mm a−1. Basement thrusting and thickening of the crust are restricted to the NE part of the Zagros belt. This is also reflected in the regional topography and in the distribution of uplifted terraces. In the southwestern part, the deformation is limited mainly to folding and thrusting of the sedimentary cover above a Triassic basal detachment. In the NE, deformation is associated with slip on basement thrusts. Our study sheds light on the distribution of shortening in the Zagros Mountains and helps to understand the regional tectonic system. Our results may be the foundation for a better seismic hazard assessment of the entire area.

AbstractThe coupling response between solar wind structures and the magnetosphere is highly complex, leading to different effects in the outer radiation belt electron fluxes. Most Coronal Mass Ejections cause strong geomagnetic storms with short recovery phases, often 1–2 days. By contrast, High‐Speed Solar Wind Streams lead to moderate and weak storms often with much longer recovery phases, from several to ∼10 days. The magnetosphere receives energy for a long time under the influence of the HSSs, considerably changing its dynamics. This in turn has an effect on the charged particles trapped in the outer radiation belt. Although the high‐energy electron flux enhancements have received considerable attention, the high‐energy electron flux enhancement pattern (L > 4) has not. This paper identifies 37 events with this enhancement pattern in the high‐energy electron flux during the Van Allen Probes era. We find the enhancements coincident with HSS occurrence. The interplanetary magnetic field (IMF) exhibits north/south Bz fluctuations of Alfvénic nature with moderate amplitudes. The high‐energy electron flux enhancements also correspond to long periods of auroral activity indicating a relationship to magnetotail dynamics. However, the AE index only reaches moderate values. Ultra‐Low Frequency waves were present in all of the events and whistler‐mode chorus waves were present in 89.1% of the events, providing a convenient scenario for wave‐particle interactions. The radial gradient of the ULF wave power related to the L, under the influence of the HSSs, is necessary to trigger the physical processes responsible for this type of high‐energy electron flux enhancement pattern.

AbstractQuantifying the strength evolution of faults that cut the lithosphere is essential to better understand seismicity in continental regions. We estimate differential stresses and principal stress orientations driving rapid slip of ∼10 mm/yr on the active Mai'iu low‐angle normal fault (LANF), SE Papua New Guinea. The fault's mafic footwall hosts a well‐preserved sequence of mylonite, (ultra‐)cataclasite, and gouge. In these fault rocks, we combine stress inversion of fault‐slip data and paleostress analysis of syntectonically emplaced calcite veins with microstructural and clumped‐isotope geothermometry to constrain a syn‐exhumational sequence of deformation stresses and temperatures, and to construct a stress profile through the exhumed footwall of the active Mai'iu LANF. This includes: (a) at ∼12–20 km depth (T ≈ 275–370°C), mylonites accommodated slip on the Mai'iu fault at low differential stresses (>25–135 MPa) before being overprinted by localized brittle deformation at shallower depths; (b) at ∼6–12 km depth (T ≈ 130–275°C) differential stresses in the foliated cataclasites and ultracataclasites were high enough (>150 MPa) to drive slip on a mid‐crustal portion of the fault (dipping 30–40°), and to trigger brittle yielding of mafic footwall rocks in a zone of mixed‐mode seismic/aseismic slip; and (c) at shallower crustal depths (T < 150°C; depth <6 km) on the most poorly oriented segment of the Mai'iu LANF (dipping ∼22°), slip occurred on frictionally weak clay‐rich gouges (μ ≈ 0.15–0.38). Subvertical σ1 and subhorizontal σ3 parallel to the extension direction, with σ1 ≈ σ2 (constriction), reflect vertical unloading and 3‐D bending strain during rolling‐hinge style flexure of the footwall.
