Scattering of Superthermal Ions at Shocks: Dependence on Energy
Authors: Gedalin Michael , Ganushkina Natalia , Pogorelov Nikolai V. , Roytershteyn Vadim 
Published: November 2023

Abstract
Diffusive shock acceleration requires the production of backstreaming superthermal ions (injection) as a first step. Such ions can be generated in the process of scattering of ions in the superthermal tail off the shock front. Knowledge of the scattering of high-energy ions is essential for matching conditions of upstream and downstream distributions at the shock transition. Here we analyze the generation of backstreaming ions as a function of their initial energy in a model stationary shock and in a similar rippled shock. Rippling substantially enhances ion reflection and the generation of backstreaming ions for slightly and moderately superthermal energies, and thus is capable of ensuring ion injection into a further diffusive shock acceleration process. For high-energy ions, there is almost no difference in the fraction of backstreaming ions produced and the ion distributions between the planar stationary shock and the rippled shock.
Toward Measuring the Microlensing Event Rate in the Galactic Center. I. Event Detection from the UKIRT Microlensing Survey Data
Authors: Wen Yongxin , Zang Weicheng , Ma Bo 
Published: November 2023

Abstract
To overcome the high optical extinction, near-infrared (NIR) observations are needed for probing the microlensing events toward the Galactic center. The 2015–2019 UKIRT microlensing survey toward the Galactic center is the first dedicated precursor NIR survey for the Nancy Grace Roman Space Telescope. Here, we analyze the online data from the UKIRT microlensing survey, reaching l = b = 0°. Using the event-finder algorithm of KMTNet with the Δχ
2 threshold of 250, we find 522 clear events, 436 possible events, and 27 possible anomalous events. We fit a point-source point-lens (PSPL) model to all the clear events and derive the PSPL parameters with uncertainties using a Markov Chain Monte Carlo method. Assuming perfect detection efficiency, we compute the uncorrected event rates, which should serve as the lower limits on the true event rate. We find that the uncorrected NIR event rates are likely rising toward the Galactic center and are higher than the optical event rates.
Radical-Right Parties, their Foreign Policy Positions on Russia and in the European Parliament
Authors: Timofejevs Pēteris F. 
Published: November 2023

À partir de l’exemple balte, cet article examine l’hypothèse selon laquelle les partis de droite radicale sélectionnent leurs partenaires au Parlement européen sur la base soit d’affinités idéologiques, soit de respectabilité nationale. Deux cas sont systématiquement comparés : le Parti populaire conservateur d’Estonie (EKRE) et l’Alliance nationale lettone (NA). Les résultats empiriques indiquent que les positions de politique étrangère vis-à-vis de la Russie de ces deux partis baltes diffèrent de celles des partis de droite radicale ailleurs dans l’Union européenne. Cependant, ce constat ne peut pas expliquer les attitudes différentes qu’ils adoptent sur la scène nationale et au Parlement européen. L’AN est restée l’une des plus critiques de la Russie, tant en Lettonie que dans l’UE, tandis que l’EKRE est entrée dans un gouvernement de coalition dirigé par un parti plus favorable à la Russie, le Parti du centre, tout en s’alliant avec le groupe du parti parlementaire « Identité et démocratie » au Parlement européen.
National Homogeneity as a Component of the Far-Right Narrative in Poland
Authors: Różycki Bartłomiej 
Published: November 2023

Cet article discute de l’importance du concept « d’homogénéité nationale » en Pologne. Paradoxalement, cette notion a été utilisée avant la seconde guerre mondiale, et ensuite sous le régime communiste, elle l’est désormais par des forces politiques contemporaines, dont Droit et Justice (PiS), le parti ouvertement anticommuniste qui gouverne la Pologne depuis 2015. Ce concept est réinvesti par l’extrême droite sous une grande variété de formes, allant d’initiatives populaires à la rhétorique gouvernementale. L’attachement d’une partie de la population à ce concept est une des explications des récents succès électoraux du PiS.
Retour sur Dora, le grain de sable et la perle : de la trace somatique à la conversion
Authors: Tabacof Diana 
Published: November 2023

La relecture du cas Dora par les psychosomaticiens français une cinquantaine d’années après sa publication a permis de faire ressortir la dimension traumatique et le noyau d’angoisse actuelle présents dans le matériel clinique de la célèbre patiente de Freud. À partir de certains concepts du corpus psychosomatique comme ceux de fixation somatique et noyau traumatique, l’auteur interroge la notion de « complaisance somatique » et de ses destins, celle-ci pouvant devenir un symptôme symbolique dans la lignée conversionnelle (perle), ou bien, rester pure trace d’excitations non-symbolisées (grain de sable) propre à la lignée traumatique (selon M. Fain) se manifestant par des symptômes somatiques. La lecture croisée du cas Dora et des Trois essais sur la théorie sexuelle, écrits à peu près en même temps, permet aussi de saisir les singularités des investissements libidinaux des zones érogènes et d’envisager l’émergence d’un corps pulsionnel porteur de traces, potentiellement hystérogènes ou traumatiques.
Traces et plasticités en psychanalyse, neurosciences et dans l’Intelligence Artificielle
Authors: Chaudoye Guillemine , Zebdi Rafika 
Published: November 2023

La notion de traces laissées par l’expérience est à l’interface de la psychanalyse et des neurosciences dans ce qu’elles permettent, en termes de plasticité, tant psychique que neuronale. Alors que Freud, dès 1895, proposait un projet pour une psychologie scientifique, en parallèle, le champ des neurosciences se faisait jour et allait ouvrir à de nouvelles perspectives de pensées et de connaissances. Les traces, preuves de l’expérience acquise, vont être ce qui va permettre de penser un travail de mémoire tant dans sa dimension psychique que neurologique. Mais à ces plasticités psychiques et cérébrales, bientôt va se joindre une nouvelle : celle des neurones artificiels, toile de fond d’un champ de recherche et d’ouverture dont on ne connaît pas encore l’envergure : l’intelligence artificielle, elle aussi sujette à expérience, elle aussi empreinte de traces, laissant présager de sa propre plasticité.
Le temps perdu de l’attente
Authors: Saïet Mathilde 
Published: November 2023

Il s’agit d’interroger ici la « situation d’impasse » (Sami-Ali) dans laquelle sont parfois placés les sujets « en attente » (« sans-papiers », « migrants », « demandeurs d’asile », etc.) et les conséquences d’une telle attente sur les processus psychiques et, en particulier, sur l’organisation de la temporalité. Cette attente, qui s’allonge comme à l’infini, entraînant désœuvrement et enlisement dans un quotidien marqué par la répétition, immobilise en effet le sujet dans un temps suspendu qui semble profondément altérer les processus de temporalisation. Les conceptualisations freudiennes concernant la temporalité seront convoquées pour saisir ce qui peut ainsi apparaître comme une figure du « temps éclaté » (Green). Le texte de Samuel Beckett, En attendant Godot, servira de fil conducteur pour tenter d’appréhender ce qu’engendre cette contrainte à la répétition et l’instauration de ce régime de « l’actuel ».

Published: November 2023

Cet article se propose d'analyser les modes de persistance de la soi-disant « explosion sociale » qui s'est produit au Chili entre octobre 2019 et mars 2020, en considérant deux phénomènes : d'une part, l'opération systématique d'effacement des traces de la révolte populaire de l'espace public ; et, d'autre part, le récent rejet de la proposition de nouvelle Constitution. Ce travail traite des débris et des spectres de la révolte, pour lesquels est proposée une nécro-archive de l’ « explosion sociale », où sont assemblés les différents rythmes du processus, dans l'intention de repenser les diverses réverbérations des événements.
Connectomique urbaine. Une étude pilote pour la ville de Messine
Authors: La Fauci Giovanni 
Published: November 2023

Qu’est-ce qui rend une ville unique ? À partir de quelques contributions théoriques et empiriques remarquables, l’article tentera de montrer comment l’image urbaine est toujours le résultat d’un « processus collectif continu de re-signification » (Boeri, 2016). C’est un imaginaire qui opère à travers des représentations sociales spatialisées selon des connexions structurelles, fonctionnelles et émergentes. L’hypothèse est que ces connexions ont non seulement une évidence géographique mais une topologie, pas du tout neutre, qui qualifie de manière caractéristique la marque mentale d’une ville. À travers l’étude des connectivités structurelles et fonctionnelles de certaines représentations sociales dans l’espace géographique, nous arriverons à l’élaboration de cartes qui, en raison de l’approche méthodologique particulière, sont ici définies comme des connectomes urbains .
Une vulnérabilité dévoyée : le paradoxe entre discours et réalité du travail des femmes au sein d’une Scop industrielle
Authors: Reichhart Ada 
Published: November 2023

Les sociétés coopératives et participatives (Scop) se présentent comme une alternative démocratique à l’organisation inégalitaire du travail. Pourtant, l’étude d’une Scop industrielle rend compte sur le long terme d’une justification de la relégation des femmes à des postes définis par leur « petitesse », par une essentialisation de leur vulnérabilité entendue comme fragilité des corps. Or, comme le concède paradoxalement l’ensemble des salarié·e·s, les postes occupés par les femmes se révèlent être parmi les plus pénibles. Ce processus d’invisibilisation du travail laborieux des femmes concourt à un dévoiement de la notion de vulnérabilité dont la déconnection avec le vécu est source de tensions. Le résultat est une contradiction entre la représentation sociale de la vulnérabilité et la réalité de l’usage et de l’exposition des corps dans une entreprise où cette dimension est pourtant essentielle, venant mettre en cause de façon sous-jacente la promesse démocratique de la Scop.
Quand l’articulation des temps éclaire les positions sociales
Authors: Landour Julie 
Published: November 2023

Si l’étude des indépendant·e·s connaît un récent essor, les derniers travaux ne fournissent encore qu’une vue éparpillée des logiques de structuration d’un espace non-salarié qui connaît des transformations importantes à la croisée des mutations de l’emploi et de la famille. Cet article propose, à l’appui d’analyses géométriques des données conduites sur la vague 2016 de l’enquête « Conditions de travail et risques psycho-sociaux », de contribuer aux analyses visant à éclairer le positionnement social des indépendant·e·s à partir de leurs pratiques en matière d’articulation entre les temps dédiés à l’emploi et ceux dédiés aux activités hors-emploi.
Elucidating the involvement of neutrophil extracellular traps in hemarthrosis pathophysiology
Authors: Mohammed Rusul Qasim , Ahmed Abeer Anwer 
Published: November 2023

BACKGROUND:Hemophilia is an inherited bleeding disorder that could cause many complications, one of which is hemarthrosis. Neutrophils are the predominant immune cells that infiltrate joints after hemorrhage. Tissue injury is often accompanied by the production of neutrophil extracellular traps (NETs), which are DNA constructs containing attached granular enzymes.AIMS OF STUDY:The aim of this study was to identify the presence of neutrophil extracellular traps including the neutrophil elastase (NE) and myeloperoxidase (MPO), in patients with hemophilia A presented with hemarthrosis.SUBJECTS AND METHODS:During a period of 8 months from November 2022 to June 2023, 50 persons were recruited cross-sectional study was conducted. In the current study, a sample of 25 individuals with hemophilia A presenting with hemarthrosis were included. Additionally, a control group of 25 unrelated, almost healthy persons,matched in terms of age and sex were also included. NE and MPO levels in blood were measured by flow cytometry technique.RESULTS:The level of MPO and NE in the blood was significantly higher in hemophilia A patients than controls. In the results of hemophilia A patients, the mean and standard deviation of MPO were 3253.36 +_1865.48, while for NE it was 5229.08+_2667.43. These values were found to be statistically significantP<0.05 when compared to the control group. In the control group, the mean and standard deviation of MPO were 2285.48+_811.89, and for NE, it was 3816.92+_1890.45.CONCLUSIONS:Patients with hemarthrosis had a considerably increase level of NETs in their blood than healthy individuals, and these findings indicate a function of NETs in the pathology of hemophilia A with hemarthrosis.
Prevalence of postpartum depression & anxiety among women in rural India: Risk factors & psychosocial correlates
Authors: Dadhwal Vatsla , Sagar Rajesh , Bhattacharya Debabani , Kant Shashi , Misra Puneet , Choudhary Vandana , Vanamail Perumal 
Published: November 2023

Background & objectives:
Postpartum depression and anxiety (PPD/A) impact a woman’s physical and psychological wellbeing. In the absence of corroboratory evidence from the community setting in India, the present study was undertaken to examine the prevalence, psychosocial correlates and risk factors for PPD/A in the rural community of India.

Methods:
This cross-sectional study included 680 women during the postpartum period from a rural community in northern India. Screening for PPD/A was done using Edinburg Postnatal Depression Scale and State and Trait Anxiety Inventory. Diagnostic assessment of screened-positive women was done using Mini-International Neuropsychiatric Interview (MINI). The psychosocial evaluation was done on parameters including women’s social support, bonding with the child, functionality, parental stress, interpersonal violence and marital satisfaction.

Results:
The overall prevalence of PPD/A/both in community women was 5.6 per cent, with a specific prevalence of 2.2 per cent for PPD, 0.74 per cent for PPA and 2.8 per cent for both disorders. Comparative analysis indicated that women with PPD/A/both experienced significantly higher levels of parenting stress, poor lifestyle (prior two weeks), less support from their partner, parents-in-law and parents, less marital satisfaction, high intimate partner violence, poor bonding with infants and higher infant-focussed anxiety. On multivariable logistic regression analysis, higher education, marital satisfaction, support from partners and in-laws were associated with reducing the risk of PPD/A/both.

Interpretation & conclusions:
Rural Indian women experience PPD/A/both which causes stress and impacts their functionality, bonding with the infant and relationship with their spouse and parents. Higher education, marital satisfaction and higher support from partners and in-laws reduce the risk of developing PPD/A/both.
Safe sites for buccal shelf bone screw placement in various skeletal malocclusions: A CBCT study
Authors: Athira V M , Shashidhar Keerthan , Kuttappa M N , Nayak U S Krishna , Ravi M S , D'Souza Neevan 
Published: November 2023

INTRODUCTION:
The mandibular buccal shelf area is an extra-alveolar anchorage site that has high quality and quantity of bone, provides biomechanical benefits and has low failure rates. It is essential to place the implant in the region of bone with optimal thickness. The aim of this study was to determine the suitable site of the mandibular buccal shelf for bone screw insertion at 90 degrees and 30 degrees angles of insertion and various heights, angulations, areas of the buccal shelf in prognathic and retrognathic mandibles, and vertical and horizontal growth patterns.

METHODS:
In this retrospective study, we evaluated the cone-beam computed tomography (CBCT) images of 48 patients in the age range of 18–30 years, divided into four groups. Seven sectional sites were examined at 3, 5, and 7 mm from the alveolar crest at 90 degrees and 30 degrees. The angulation and area of the buccal shelf were examined.

RESULTS:
Cortical bone thickness increased distally from the first to the second molar in all four groups.

CONCLUSIONS:
The preferred site for buccal shelf implant placement was distal to the mandibular second molar. The maximum amount of cortical bone was observed distal to the second molar, 7 mm vertically from the alveolar crest, when the buccal shelf implant was placed at 30 degrees angulation to the long axis of the tooth.
Evaluation of changes in tongue pressure with twin-block appliance therapy in growing Class II Div 1 malocclusion. An in vivo study

Published: November 2023

INTRODUCTION:
Twin-block appliance therapy in patients with Class II Div 1 malocclusion positions the mandible anteroinferior leading to possible alterations in tongue pressure, tongue length, and the oropharynx.

OBJECTIVES:
To evaluate the changes in tongue pressure, tongue length and dimension of the pharyngeal airway in Class II Division 1 subjects before and after twin-block therapy.

MATERIALS AND METHODS:
Twenty-four subjects were selected, in the range of 10–14 years (mean—12 years). The tongue pressure was recorded at three regions with sensors placed at the incisive papilla and bilaterally at the molar region of the palate for four minutes. The root mean square (RMS) values were recorded and used for further analysis. Evaluation of tongue length and pharyngeal airway dimension was done using a lateral cephalogram. All the measurements were done before and after twin-block appliance therapy. The paired t-test was performed to compare the changes.

RESULTS:
Resting tongue pressures decreased from pre-treatment levels to post-treatment at all three regions. Change in ANB angle was found to have a significant negative correlation with tongue length, and pharyngeal airway dimension, a significant positive correlation with pressure at incisive papilla and left molar region and no correlation at right molar region.

CONCLUSION:
There was a decrease in resting tongue pressure as the malocclusion was corrected from Class II to Class I. Hence, this decrease in pressure could be a contributory factor in the maintenance of the dental equilibrium as lighter forces exist in the oral cavity.

ABSTRACT.
Acinetobacter baumannii poses a significant threat to public health due to the high rate of multidrug-resistant strains. However, information on the molecular characterization of carbapenem-resistant Acinetobacter baumannii (CRAB) bloodstream infections in children is scarce. This study aimed to describe the molecular characterization of carbapenem-resistant A. baumannii infections in children from a hospital in Mexico. A retrospective study was conducted during the period 2017–2022. Clinical and demographic data were collected from the clinical records. Mass spectrometry was used for the identification of the strains. To confirm A. baumannii strains, a polymerase chain reaction (PCR) method was applied using a gyrB sequence. The carbapenemase-encoding resistance genes were detected by PCR. Six cases of CRAB were documented, including five in neonates. The median intensive care unit stay was 20 days, and all cases had an invasive medical device. Half of the patients had at least one medical condition. A high prevalence of coresistance was observed in most of the antibiotic groups. Three of the six strains coharbored carbapenemase genes: blaOXA-51, blaOXA-24, and blaIMP. Mortality was reported in two neonate patients. The present study shows a high rate of coharboring blaOXA-51, blaOXA-24, and blaIMP-1, which has a direct impact on therapeutic decisions. Implementation of antimicrobial stewardship programs is urgent to stop the spread of this microorganism.

ABSTRACT.
Vector-borne diseases continue to impose a major health burden on Peru and neighboring countries. The challenge of addressing vector-borne disease is compounded by changing social, economic, and climatic conditions. Peri-urban Arequipa is an important region to study insect infestations because of ongoing challenges with disease vectors such as triatomines and a variety of other insects. We conducted surveys (N = 1,182) and seven focus groups (average seven participants) in peri-urban Arequipa to explore knowledge of and perception toward various insects that infest the region. Focus group participants reported the presence of a wide variety of insects in and around the home, including disease vectors such as triatomines (also identified by 27.2% of survey households), mosquitoes, spiders, and bed bugs, as well as nuisance insects. Health concerns related to insects included vector-borne diseases, spider bites, allergies, and sequelae from bed bug bites, and hygiene concerns. A majority of participants in the quantitative surveys identified triatomines as the insect they were most worried about (69.9%) and could identify Chagas disease as a health risk associated with triatomines (54.9%). Insect infestations in peri-urban Arequipa present multiple burdens to residents, including injury and illness from triatomines and other insects, as well as potential mental and economic concerns related to insects such as bed bugs. Future initiatives should continue to address triatomine infestations through educational outreach and implement a more holistic approach to address the burden of both disease and nuisance insects.

ABSTRACT.
Onchocerciasis has been declared eliminated in Ecuador and surveillance measures are of great interest. In this study, we examined the infectivity rates of Simulium exiguum by Onchocerca volvulus in previously hyperendemic areas in Esmeraldas province of Ecuador. These areas had previously undergone mass administration of ivermectin, which led to the interruption of transmission in 2009 and the certification of elimination in 2014. The study included three communities in Río Cayapas and one in Río Canandé, and a total of 2,950 adult S. exiguum were collected in 2018. We used quantitative polymerase chain reaction with O. volvulus O-150 plasmid control DNA to analyze 59 pools. Our findings revealed that the infectivity rates were zero, indicating that the transmission of O. volvulus remained suspended in the area.
