Abstract
Radial velocity (RV) is among the most fundamental physical quantities obtainable from stellar spectra and is rather important in the analysis of time-domain phenomena. LAMOST Medium-resolution Survey (MRS) DR7 contains five million single-exposure stellar spectra with spectral resolution R ∼ 7500. However, the temporal variation of the RV zero-points (RVZPs) of the MRS, which makes the RVs from multiple epochs inconsistent, has not been addressed. In this paper, we measure the RVs of 3.8 million single-exposure spectra (for 0.6 million stars) with signal-to-noise ratios (S/N) higher than 5 based on the cross-correlation function method, and propose a robust method to self-consistently determine the RVZPs exposure by exposure for each spectrograph with the help of Gaia DR2 RVs. Such RVZPs are estimated for 3.6 million RVs and can reach a mean precision of ∼0.38 km s−1. The result of the temporal variation of RVZPs indicates that our algorithm is efficient and necessary before we use the absolute RVs to perform time-domain analyses. Validating the results with APOGEE DR16 shows that our absolute RVs can reach an overall precision of 0.84/0.80 km s−1 in the blue/red arm at 50 < S/N < 100 and of 1.26/1.99 km s−1 at 5 < S/N < 10. The cumulative distribution function of the standard deviations of multiple RVs (N
obs ≥ 8) for 678 standard stars reaches 0.45/0.54, 1.07/1.39, and 1.45/1.86 km s−1 in the blue/red arm at the 50%, 90%, and 95% levels, respectively. Catalogs of the RVs, RVZPs, and selected candidate RV standard stars are available at https://github.com/hypergravity/paperdata.

Abstract
We have used the Taeduk Radio Astronomy Observatory to observe the Orion A and Ophiuchus clouds in the J = 1−0 lines of 13CO, C18O, HCN, HCO+, and N2H+ and the J = 2−1 line of CS. The fully sampled maps with uniform noise levels are used to create moment maps. The variations of the line intensity and velocity dispersion with total column density, derived from dust emission maps, are presented and compared to previous work. The CS line traces dust column density over more than one order of magnitude, and the N2H+ line best traces the highest column density regime (

The HCO+-to-HCN luminosity ratio in the Orion A cloud is similar to that of starburst galaxies, while that in the Ophiuchus cloud is in between those of active galactic nuclei and starburst galaxies.
No Evidence for Time Variation in Saturn’s Internal Magnetic Field

Abstract
The time variation of a planetary magnetic field can reveal important aspects of a planet's interior structure. Searching for time variation in planetary magnetic fields other than Earth has proved challenging owing to the small number of spacecraft missions flown to date, but such a detection may be possible given a sufficiently long baseline for comparison. Here we leverage 38 years of spacecraft magnetometer measurements to search for time variation in Saturn’s internal magnetic field. To isolate the possible signal of time variation, we remove a contemporary high-resolution internal field model, derived from Cassini data, as well as a best-fitting external magnetodisk field model from each of four past mission data sets: Pioneer 11 (1979), Voyager 1 (1980), Voyager 2 (1981), and Cassini Saturn Orbit Insertion (2004). We then attempt to fit the resulting signal with an axisymmetric internal field model. Overall, we find no evidence of time variation on a multidecadal timescale. Our results lend support to the existence of a stably stratified layer in Saturn and have comparative planetology implications for Jupiter’s interior structure and dynamics.
On the multiple temporalities of Guna woodcarving
Authors: Fortis Paolo 
Published: September 2021

Cet article explore les notions de temporalité qui se dégagent de l’étude ethnographique de la sculpture rituelle sur bois chez les Guna du Panama. S’appuyant sur le concept de « cartes du temps » d’Alfred Gell, il montre que la sculpture sur bois des Guna est un outil de navigation temporelle qui permet d’accéder à de multiples images du temps grâce aux qualités de ces artefacts qui acquièrent un sens à travers les relations intersubjectives. Les figures rituelles en bois donnent accès à l’action différée du temps d’origine en établissant une synchronisation avec le temps biographique humain et avec le temps des esprits qui en sont les propriétaires. La sculpture sur bois doit donc être considérée comme un processus matériel qui s’engage récursivement à la fois dans la connaissance historique et l’expérience vécue, les rendant mutuellement significatives, jetant ainsi un pont entre les processus individuels et collectifs variant avec le temps.
Rendre « propre » son enfant selon son « rythme » individuel
Authors: Chantseva Victoria 
Published: September 2021

En France, les parents des jeunes enfants sont confrontés à un paradoxe : d’un côté, l’institution scolaire exige que les enfants entrent à l’école maternelle sans couches à 3 ans et, de l’autre, il est attendu que les parents respectent le « rythme » individuel de l’enfant en évitant de le forcer à abandonner les couches (norme véhiculée par les pédiatres et les professionnelles de la petite enfance). Comment cette contradiction normative est-elle gérée par les familles ? En s’appuyant sur un corpus d’entretiens avec des parents (principalement des mères) de différentes catégories socioprofessionnelles, ainsi que sur une enquête réalisée dans une crèche, l’article examine ces injonctions institutionnelles contradictoires et étudie la façon dont les parents composent avec celles-ci. Quelques attitudes éducatives (« militante », « pragmatique », « anticipation sereine », « anticipation fébrile ») seront examinées de manière à présenter les différentes façons d’agir face aux contraintes en question.
Conservation of Northwestern and Southwestern Pond Turtles: Threats, Population Size Estimates, and Population Viability Analysis

Abstract
Accurate status assessments of long-lived, widely distributed taxa depend on the availability of long-term monitoring data from multiple populations. However, monitoring populations across large temporal and spatial scales is often beyond the scope of any one researcher or research group. Consequently, wildlife managers may be tasked with utilizing limited information from different sources to detect range-wide evidence of population declines and their causes. When assessments need to be made under such constraints, the research and management communities must determine how to extrapolate from variable population data to species-level inferences. Here, using three different approaches, we integrate and analyze data from the peer-reviewed literature and government agency reports to inform conservation for northwestern pond turtles (NPT) Actinemys marmorata and southwestern pond turtles (SPT) Actinemys pallida. Both NPT and SPT are long-lived freshwater turtles distributed along the west coast of the United States and Mexico. Conservation concerns exist for both species; however, SPT may face more severe threats and are thought to exist at lower densities throughout their range than NPT. For each species, we ranked the impacts of 13 potential threats, estimated population sizes, and modeled population viability with and without long-term droughts. Our results suggest that predation of hatchlings by invasive predators, such as American bullfrogs Lithobates catesbeianus and Largemouth Bass Micropterus salmoides, is a high-ranking threat for NPT and SPT. Southwestern pond turtles may also face more severe impacts associated with natural disasters (droughts, wildfires, and floods) than do NPT. Population size estimates from trapping surveys indicate that SPT have smaller population sizes on average than do NPT (P = 0.0003), suggesting they may be at greater risk of local extirpation. Population viability analysis models revealed that long-term droughts are a key environmental parameter; as the frequency of severe droughts increases with climate change, the likelihood of population recovery decreases, especially when census sizes are low. Given current population trends and vulnerability to natural disasters throughout their range, we suggest that conservation and recovery actions first focus on SPT to prevent further population declines.
La mise en récit des dissidences religieuses
Authors: Montantou Matthieu 
Published: September 2021

L’enjeu de ce travail est de proposer quelques pistes de réflexion pour cerner le récent renouvellement de l’historiographie des dissidences médiévales. Il s’agit en effet de s’interroger sur les ressources à la disposition des historiens pour saisir les deux niveaux de réalité historique : car il semble nécessaire de distinguer clairement les phénomènes eux-mêmes des discours dont ils sont les supports. L’historien doit ainsi s’efforcer de gérer ces discours, à la fois lorsqu’il étudie les traces du passé et lorsqu’il tente d’en rendre compte en l’intellectualisant, ce qui est le propre du travail historique. Cet article considère ainsi les deux niveaux de confrontation des historiens à ce que Foucault nomme les discours.
Mechanical Properties and Interface Microstructure of SAC305 Solder Joints Made to an Ag-Pd-Pt Thick Film Metallization: Part 1—Processing Effects

Published: September 2021

Abstract
The processibility was document for interconnections made between the 96.5Sn-3.0Ag-0.5Cu (wt.%, abbreviated SAC305) Pb-free solder and an Ag-Pd-Pt thick film conductor on an alumina substrate. The Sheppard’s hook pull test was used to assess the solder joint strength. Microanalysis techniques documented the corresponding microstructures. Excellent solderability was observed across the process parameters defined by the soldering temperatures of 240–290°C and soldering times of 15–120 s. Molten SAC305 solder dissolved the Ag-Pd-Pt thick film, leading to the precipitation of Ag (trace of Pd) and (Pd, Pt)xSny intermetallic compound (IMC) particles upon solidification. The mechanical strengths of the solder joints were excellent (10–15 N) and remained largely insensitive to the processing conditions. The failure mode was ductile fracture in the solder. These findings confirmed that the SAC305 solder/Ag-Pd-Pt thick film interconnection system had the necessary process window for use in high reliability, hybrid microcircuit (HMC) applications.

Abstract
The performance and reliability were documented for solder joints made between the 96.5Sn-3.0Ag-0.5Cu (wt.%, abbreviated SAC305) Pb-free solder and a Ag-Pd-Pt thick film conductor on an alumina substrate. The Sheppard’s hook pull test was used to assess the solder joint strength. The Part 1 study confirmed that the solder joint fabrication process had a wide process window. The current study determined that the SAC305 solder joints maintained that robustness after accelerated aging at temperatures of 70–205°C and time durations of 5–200 d. Short-term aging of 5–10 d caused a peak in the pull strength peak that resulted from precipitation hardening by Ag-Pd and (Pd, Pt)xSny intermetallic compound (IMC) particles. The pull strengths did not decrease significantly after longer aging times at 70°C and 100°C; those conditions were accelerations of typical service lifetimes. Longer aging times at temperatures of 135–205°C resulted in a gradual, albeit not catastrophic, strength decrease when the precipitation hardening mechanism was lost to dissolution of the particle phases and their reprecipitation at the solder/alumina interface. The failure modes were ductile fracture in the solder except for the most severe aging conditions. These findings confirmed that the SAC305 solder/Ag-Pd-Pt thick film interconnections have excellent long-term reliability for hybrid microcircuit and high-temperature electronics applications.

Published: September 2021

Objective:
The clinical outcome following multilevel stabilization in patients who suffered cervical spinal injury and developed severe neurological deficits and then gradually partially recovered is evaluated. The basis of the surgical concept was that cervical spinal degeneration is a result of single or multilevel spinal instability and that spinal trauma exaggerates the instability.

Materials and Methods:
During the period 2015–2020, 14 patients who suffered severe cervical spinal injury and could be included in the classification of spinal cord injury without computed tomography evidence of trauma were surgically treated. There were 11 males and 3 females. The ages ranged from 45 to 67 years, average being 53 years. Cervical canal stenoses related to degenerative spinal changes were observed in all patients. All patients suffered severe neurological deficits and within few days or weeks had shown significant but incomplete neurological recovery. The identification of the levels of unstable spinal segments was done on the basis of radiological and clinical parameters and direct observation of spinal instability in adjoining spinal segments. Transarticular fixation was done by Camille's transarticular fixation technique. Using ASIA score, modified JOA score, and Goel Clinical Grading Scale, the clinical course of the patients was monitored.

Results:
All patients showed recovery in the neurological status. Recovery started in the immediate postoperative period and the improvement progressed during the period of follow-up.

Conclusions:
Surgery for spinal stabilization can be indicated even in cases that improve in the neurological function.

Published: September 2021

Objective:
The goal of the study was to retrospectively evaluate the demographics, clinical manifestation, outcomes, treatment result, and survival of patients with spinal metastasis with epidural metastasis who underwent surgical treatment.

Materials and Methods:
A retrospective evaluation of 103 patients with spinal metastasis and epidural compression who underwent surgical treatment between 2009 and 2015 was performed. The recorded parameters selected for the study were general demographic data (gender, age, and educational level) and clinical data (primary tumor, performance status according to Karnofsky score, neurological status according to Frankel scale, pain, surgical treatment outcomes, and patient survival).

Results:
The mean age of the patients was 55.28 ± 15.79 years, and spinal metastasis was more frequent in males (61.7%). The two most frequent tumors were malignant breast cancer (26.21%) and prostate cancer (22.33%). Preoperative pain was presented in 96 (94.12%) patients and improvement was observed in 44 (47.31%) patients. Symptoms of spinal cord compression were the initial clinical manifestation of the primary tumor in 35 (33.98%) patients. Neurological deficit was observed in 66 (64.07%) patients, and improvement was observed in 43 (41.74%) patients. Improvement of functional outcome and pain was observed in 34 (37.38%) patients. The mean survival was 12.26 months. Longer survival (mean 19.13 months) was observed in patients who showed improvement in their ability to walk or kept it preserved (Frankel D or E).

Conclusions:
Surgical treatment of spinal metastasis can improve pain and functional activities. Longer survival was observed in patients that keep or recovery the walking ability.
Autonomous lumbar spine pedicle screw planning using machine learning
Authors: Siemionow Kris B. , Forsthoefel Craig W. , Foy Michael P. , Gawel Dominik , Luciano Christian J. 
Published: September 2021

Introduction:
Several techniques for pedicle screw placement have been described including freehand techniques, fluoroscopy assisted, computed tomography (CT) guidance, and robotics. Image-guided surgery offers the potential to combine the benefits of CT guidance without the added radiation. This study investigated the ability of a neural network to place lumbar pedicle screws with the correct length, diameter, and angulation autonomously within radiographs without the need for human involvement.

Materials and Methods:
The neural network was trained using a machine learning process. The method combines the previously reported autonomous spine segmentation solution with a landmark localization solution. The pedicle screw placement was evaluated using the Zdichavsky, Ravi, and Gertzbein grading systems.

Results:
In total, the program placed 208 pedicle screws between the L1 and S1 spinal levels. Of the 208 placed pedicle screws, 208 (100%) had a Zdichavsky Score 1A, 206 (99.0%) of all screws were Ravi Grade 1, and Gertzbein Grade A indicating no breech. The final two screws (1.0%) had a Ravi score of 2 (<2 mm breech) and a Gertzbein grade of B (<2 mm breech).

Conclusion:
The results of this experiment can be combined with an image-guided platform to provide an efficient and highly effective method of placing pedicle screws during spinal stabilization surgery.
Factors Associated with Unsuccessful Outcomes of Tuberculosis Treatment in 125 Municipalities in Colombia 2014 to 2016

ABSTRACT.
Our aim was to identify the risk factors associated with unsuccessful outcomes of tuberculosis (TB) treatment in patients diagnosed between 2014 and 2016 in the 125 municipalities of Antioquia, Colombia. We studied a retrospective cohort of patients with TB diagnosed between 2014 and 2016, from national routine surveillance systems, in 125 municipalities of Antioquia. Factors associated with unsuccessful tuberculosis treatment outcomes (treatment failed, lost to follow up, or death) were identified utilizing a Poisson regression with robust variance. Over 3 years, of the 6,739 drug-susceptible tuberculosis patients, 73.4% had successful treatment and 26.6% unsuccessful outcomes (17% lost to follow up, 8.9% deaths, and 0.7% treatment failures). Patients with subsidized health insurance (Relative risk [RR]: 2.4; 95% CI: 2.1–2.8) and without health insurance (RR: 2.5; 95% CI: 2.1–3.0) had a higher risk for unsuccessful tuberculosis treatment compared to those with contributive health insurance. Other risk factors included age over 15 years, male sex, homelessness, people living with HIV, previous treatment, and primary diagnosis during hospitalization. Protective factors were living in a rural area and extrapulmonary disease. It is important to generate strategies that improves tuberculosis diagnosis in primary healthcare institutions. In addition, it is imperative to initiate new research about the barriers and obstacles related to patients, healthcare workers and services, and the health system, including the analysis of urban violence, to understand why the goal of TB treatment success has not been reached.

ABSTRACT.
Maternal group B Streptococcus (GBS) colonization is a major risk factor for neonatal GBS infection. However, data on GBS are scarce in low- and middle-income countries. Using sociodemographic data and vaginal swabs collected from an international cohort of mothers and newborns, this study aimed to estimate the prevalence of GBS colonization among pregnant women in Madagascar (n = 1,603) and Senegal (n = 616). The prevalence was 5.0% (95% CI, 3.9–6.1) and 16.1% (95% CI, 13.1–19.0) in Madagascar and Senegal, respectively. No factors among sociodemographic characteristics, living conditions, and obstetric history were found to be associated independently with GBS colonization in both countries. This community-based study provides one of the first estimates of maternal GBS colonization among pregnant women from Madagascar and Senegal.

ABSTRACT.
Elimination of dog-transmitted human rabies worldwide will require large-scale dog vaccination campaigns. However, this places participating vaccinators at increased risk. Data from the 2016–2017 Haitian mass rabies vaccination campaign was analyzed to determine dog bite incidence among vaccinators. A survey was then developed for completion by all identifiable bitten vaccinators covering demographics; experience and training; bite episode details; attitudes toward dogs and rabies; and medical care. A parallel group of unbitten vaccinators was also surveyed. Dog bite incidence was 0.03% (43/127,000) of all dogs vaccinated. The capture, vaccinate, and release method of vaccination carried a significantly higher risk of dog bite (0.35%, 6/1,739 vaccinations) than other methods (P < 0.001). Twenty-seven bitten vaccinators, and 54 control vaccinators were included in the survey analysis. No differences were found between groups in demographics, experience, or training. However, bitten vaccinators were significantly more likely than the control group to have experienced a dog bite before the study period (P < 0.001). This may be associated with a lesser appreciation of dogs, and/or a poorer ability to interpret dog behavioral signals within this group. Although 98% of the control group indicated they would seek medical care for a dog bite, only 35% of bitten vaccinators sought such care. On a yearly basis, for the Haitian campaign, a full series of postexposure rabies vaccinations for all bite victims would prove more cost-effective than preexposure vaccination of all vaccinators. These findings may prove useful for the planning and safety of future mass dog vaccination campaigns.
