CFD Analysis of the Flow around Simplified Next-Generation Train Subjected to Crosswinds at Low Yaw Angles
Authors: Mohammad Arafat  , Izuan Amin Ishak
Published: April 2022

The development of Next-Generation Trains (NGT) made of lightweight materials is a challenging task for the transport industry. It reduces axle loads, which saves money by lowering rail track maintenance costs and the amount of energy needed to drive vehicles. However, the increasing speed and decreasing mass of high-speed trains, on the other hand, raises concerns about the effects of strong crosswinds on their aerodynamics and train stability. As a result, the purpose of this research is to investigate the unsteady flow structure around an NGT in crosswind using a Computational Fluid Dynamics (CFD) technique known as Unsteady Reynolds Averaged Navier-Stokes (URANS). Based on the height of the train model and the velocity, the Reynolds number for the simulation used was . The simulation run in four different crosswind angles: 5°, 10°, 15°, and 20°. The simulation results were compared with experimental results. The findings revealed that a larger yaw angle, which is primarily determined by the incoming wind velocity, can lead to higher flow separation and a more complex three-dimensional flow around the train. Additionally, when the wind angle is small, separation of flow and wakes is limited to the train's end; however, as the wind angle increases, separation of flow occurs from the train's upper and lower corners, indicating that the vortices formed as a result of the flow passing over the roof top and underbody. Finally, the study's findings will contribute to a better understanding of the flow characteristics around an NGT in crosswinds, which is simply impossible to achieve through full-scale testing due to the cost, resources, and accuracy.
Two-Dimensional Mixed Convection and Radiative Al2O3-Cu/H2O Hybrid Nanofluid Flow over a Vertical Exponentially Shrinking Sheet with Partial Slip Conditions
Authors: Adnan Asghar  , Teh Yuan Ying  , Khairy Zaimi
Published: April 2022

Hybrid nanofluid is considered a modern and improvised form of nanofluid which usually used to enhance the performance of heat transfer in fluid flow systems. Previous studies found hybrid nanofluid offered a wide range of applications and this opened up numerous new opportunities to further explore the unknown behaviour of hybrid nanofluid under different body geometries and physical parameters. This paper numerically studied a two-dimensional mixed convection and radiative Al2O3-Cu/H2O hybrid nanofluid flow over a vertical exponentially shrinking sheet with partial slip conditions. The main objective is to investigate the effect of mixed convection and radiation on the velocity and temperature profiles, as well as the effect of suction on reduced skin friction and reduced heat transfer with respect to solid volume fraction of copper, velocity, and thermal slips. Exponential similarity variables transformed the governing system of partial differential equations into a system of ordinary differential equations which is solved via MATLAB’s bvp4c solver. Outcomes showed that the value of the reduced heat transfer upsurges in the first solution but declines in the second solution when the velocity slip rises. The reduced heat transfer decreases in both dual solutions when thermal slip is enhanced. As the intensity of thermal slip increases, the reduced skin friction rises in the first solution and decreases in the second. As the mixed convection parameter increases, no obvious variation is noticed in the temperature distribution within the first solution, but increasing trend is observed within the second solution. An increment in the temperature distribution also observed within the dual solutions as the thermal radiation parameter increases. In summary, findings from this study are particularly useful to understand various behaviour of Al2O3-Cu/H2O hybrid nanofluid under the influence of mixed convection, radiation, and partial slip conditions when it flows over a vertical exponential shrinking sheet.
Repeated Low High-Density Lipoprotein Cholesterol and the Risk of Thyroid Cancer: A Nationwide Population- Based Study in Korea
Authors: Kim Jinyoung , Kim Mee Kyoung , Baek Ki-Hyun , Song Ki-Ho , Han Kyungdo , Kwon Hyuk-Sang
Published: April 2022

Background: High-density lipoprotein cholesterol (HDL-C) plays an important role in the reverse cholesterol transport pathway and prevents atherosclerosis-mediated disease. It has also been suggested that HDL-C may be a protective factor against cancer. However, an inverse correlation between HDL-C and cancer has not been established, and few studies have explored thyroid cancer.Methods: The study participants received health checkups provided by the Korean National Health Insurance Service from 2009 to 2013 and were followed until 2019. Considering the variability of serum HDL-C level, low HDL-C level was analyzed by grouping based on four consecutive health checkups. The data analysis was performed using univariate and multivariate Cox proportional hazard regression models.Results: A total of 3,134,278 total study participants, thyroid cancer occurred in 16,129. In the crude model, the hazard ratios for the association between repeatedly measured low HDL-C levels and thyroid cancer were 1.243, 1.404, 1.486, and 1.680 (P for trend <0.01), respectively, which were significant even after adjusting for age, sex, lifestyle factors, and metabolic diseases. The subgroup analysis revealed that low HDL-C levels likely had a greater impact on the group of patients with central obesity (P for interaction= 0.062), high blood pressure (P for interaction=0.057), impaired fasting glucose (P for interaction=0.051), and hyperlipidemia (P for interaction=0.126).Conclusion: Repeatedly measured low HDL-C levels can be considered a risk factor for cancer as well as vascular disease. Low HDL-C levels were associated with the risk of thyroid cancer, and this correlation was stronger in a metabolically unhealthy population.
Comparative Study of Ex Vivo Antiplatelet Activity of Aspirin and Cilostazol in Patients with Diabetes and High Risk of Cardiovascular Disease
Authors: Hong Sangmo , Lee Woo Je , Park Cheol-Young
Published: April 2022

Background: The role of aspirin in primary cardiovascular disease prevention in patients with diabetes remains controversial. However, some studies have suggested beneficial effects of cilostazol on cardiovascular disease in patients with diabetes. We prospectively investigated the antiplatelet effects of cilostazol compared with aspirin in patients with diabetes and cardiovascular risk factors.Methods: We randomly assigned 116 patients with type 2 diabetes and cardiovascular risk factors but no evident cardiovascular disease to receive aspirin at a dose of 100 mg or cilostazol at a dose of 200 mg daily for 14 days. The primary efficacy outcome was antiplatelet effects of aspirin and cilostazol assessed with the VerifyNow system (aspirin response units [ARU]) and PFA-100 (closure time [CT]). Secondary outcomes were changes of clinical laboratory data (ClinicalTrials.gov Identifier: NCT02933788).Results: After 14 days, there was greater decrease in ARU in aspirin (–28.9%±9.9%) compared cilostazol (–0.4%±7.1%, P<0.001) and was greater increase in CT in aspirin (99.6%±63.5%) compared cilostazol (25.7%±54.1%, P<0.001). The prevalence of aspirin resistance was 7.5% according to VerifyNow (defined by ARU ≥550) and 18.9% according to PFA-100 (CT <192 seconds). Compared with aspirin, cilostazol treatment was associated with increased high density lipoprotein cholesterol (7.1%±12.7% vs. 4.2%±18.0%, P=0.006) and decreased triglycerides (–9.4%±33.7% vs. 4.4%±17.57%, P=0.016). However, there were no significant changes in total and low density lipoprotein cholesterol, C-reactive protein level, and cluster of differentiation 40 ligand between cilostazol and aspirin groups.Conclusion: Aspirin showed better antiplatelet effects assessed with VerifyNow and PFA-100 compared with cilostazol. However, there were favorable changes in atherogenic dyslipidemia only in the cilostazol.

The in vitro assay for dissolution was evaluated by the Inductively coupled plasma-optical emission spectroscopy (ICP-OES) method. Biocompatibility testing was performed with L-929 fibroblast cells. The results show that the ZnO-doped glass systems show good bioactivity and biocompatibility.
Presentation of Low-grade Fibro Myxoid Sarcoma in Male Breast: Rare and Challenging Entity for Diagnosis - A Case Report with Review of Literature
Authors: Bhatnagar Dr. Avni , Khare Dr. Pratima
Published: April 2022

Primary breast sarcomas are very rare tumors accounting <1% of primary malignant breast tumors and <5% of soft tissue sarcomas. They are seen in young adults with tendency for multiple recurrences. They can metastasize if incompletely excised, so the prognosis is poor. There is rarity because of lack of consensus and a few case reports have been reported till date. We report a case of 31-year-old male with history of left areolar swelling. He had history of excision biopsy one year back from same site which on histopathology was diagnosed as low-grade fibro myxoid sarcoma. The patient was asymptomatic for one year and now presented with history of swelling at scar site. The lumpectomy was done. There was no systemic dissemination. The tumor was histologically diagnosed as recurrence of low-grade fibro myxoid sarcoma. We review the literature about breast sarcomas and low-grade fibro myxoid sarcoma of the breast.

We present optical photometry of six intermediate polars that exhibit transitions to a low-flux state. For four of these systems, DW Cnc, V515 And, V1223 Sgr, and RX J2133.7+5107, we are able to perform timing analysis in and out of the low states. We find that, for DW Cnc and V515 And, the dominant periodicities in the light curves change as the flux decreases, indicating a change in the sources’ accretion properties as they transition to the low state. For V1223 Sgr, we find that the variability is almost completely quenched at the lowest flux, but we do not find evidence for a changing accretion geometry. For RX J2133.7+5107, the temporal properties do not change in the low state, but we do see a period of enhanced accretion that is coincident with increased variability on the beat frequency, which we do not associate with a change in the accretion mechanisms in the system.

We report on the latest results of a Parkes multibeam survey for pulsars and dispersed radio bursts in the Large Magellanic Cloud (LMC). We conducted both periodicity and single-pulse searches at a much larger range of trial dispersion measures (DMs) than previously searched. We detected 229 single pulses with signal-to-noise ratio (S/N) > 7 that were classified by the deep-learning network FETCH as being real (with >90% likelihood), of which nine were from the known giant-pulse-emitting pulsar PSR B0540−69. Two possibly repeating sources were detected with DMs suggesting that they lie within the LMC, but these require confirmation. Only three of the 220 unknown pulses had S/N > 8, and the DM distribution for these detected pulses follows an exponential falloff with increasing DM and does not show any excess of signals at DM values expected for the LMC. These features suggest that the detected pulses are not likely to be real, although they are visually compelling. We also report the discovery of a new pulsar (PSR J0556−67) in our periodicity search. This pulsar has a spin period of 791 ms, a DM of 71 cm−3 pc, an estimated 1400 MHz flux density of ∼0.12 mJy, and shows no evidence of binary motion. Future observations may be able to confirm whether any of the weak but promising candidates in our single-pulse and periodicity searches, including our two possible repeaters, are real or not.
Novel in situ observations of asexual reproduction in the carpet sea anemone, Stichodactyla mertensii (Stichodactylidae, Actiniaria)
Authors: Bennett-Smith Morgan , Justo Micaela S. , Berumen Michael L. , Peixoto Raquel , Titus Benjamin M.
Published: April 2022

Merten’s carpet sea anemone, Stichodactyla mertensii, is the largest known sea anemone species in the world, regularly exceeding one meter in oral disc diameter. A tropical species from the Indo-Pacific, S. mertensii drapes prominently over coral reef substrates and is a common host to numerous species of clownfishes and other symbionts throughout its range, which extends from the Red Sea through the Central Pacific Ocean. Long thought to reproduce via sexual reproduction only, recent genetic evidence suggests it may rarely reproduce asexually as well, although this process has never been confirmed through direct observation and the mechanism is yet to be described. Here, we directly observed and documented in situ asexual fragmentation via budding, in real time, by a Red Sea S. mertensii in a turbid inshore reef environment. While asexual reproduction is not unusual in sea anemones as a group, it is typically expected to be uncommon for large-bodied species. Herein, we describe S. mertensii fragmentation, provide high resolution images of the event from the Saudi Arabian coastline at multiple time points, and confirm asexual reproduction for this species.
The Complete Mitochondrial Genome of the Brazilian Cownose Ray Rhinoptera brasiliensis (Myliobatiformes, Rhinopteridae) in the Western Atlantic: Genome Characterization and Phylogenetic Analysis

Published: April 2022

The Brazilian cownose ray, Rhinoptera brasiliensis has undergone a global population reduction and is currently classified by IUCN as Vulnerable. We sequenced the complete mitochondrial genome of R. brasiliensis, resulting in a 17,759 bp genome size, featuring the typical vertebrate mitochondrial genome structure. The mtDNA genome contains 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a non-coding control region (D-loop). Each PCG was initiated by an authoritative ATG codon, except for COX1 that initiated by a GTG codon. Most of the PCGs were terminated by a complete codon (TAA/TAG), while an incomplete termination codon (TA/T) was found in five out of the 13 PCGs. Both Maximum Likelihood (ML) and Bayesian Inference (BI) analyses were used to reconstruct the phylogenetic relationships which revealed that R. brasiliensis was closely related to R. steindachneri whereas the reported mitogenome from a single specimen identified as R. steindachneri from Sri Lanka (GenBank accession number KM364982) was found to correspond to the sequence for R. javanica. These novel results provide a useful resource for further phylogeographic and population genetics studies of Rhinoptera spp.

Les avancées du quinquennat 2017-2022 en matière de prévention
Authors: Bourdillon François
Published: April 2022

La prévention a été considérée comme une priorité dès 2018. À l’aune des prochaines élections présidentielles, il est apparu important de dresser un bilan des politiques publiques de santé dans ce domaine en sachant que ces dernières ont été bouleversées par la pandémie de Covid-19 toujours active. Les politiques vaccinales ont marqué le quinquennat. La lutte contre le tabac a été poursuivie et amplifiée avec notamment l’augmentation du prix du tabac pour un paquet à 10 €. En revanche, la politique contre les consommations excessives d’alcool a bien du mal à se déployer sous la pression des lobbys. En matière de nutrition la France a adopté un Plan national nutrition santé 4 et poursuivi le déploiement du Nutri-Score, d’ores et déjà adopté par six pays de l’Union européenne. Mais il n’y a toujours pas de réglementation de la publicité et du marketing des aliments en fonction de leur qualité nutritionnelle. Sont analysées également les politiques de santé sexuelle, de santé-environnement, des 1 000 premiers jours, la mise en place du service sanitaire et le passage à 80 km/h. Le fonds de lutte contre le tabac, devenu fonds de lutte contre les addictions, représente un modèle de taxes pouvant alimenter un fonds « prévention ». À quand la création d’un tel fonds alimenté par les taxes sur l’alcool, les produits particulièrement gras, sucrés et salés, les jeux et les paris ?

Quand l’État social s’adapte aux artistes. Les contreparties d’une prise en charge institutionnelle sur mesure
Authors: Sigalo Santos Luc
Published: April 2022

Résumé Depuis 1989, à Paris, le conseil général finance, au titre du RMI, puis du RSA, des prestations spécifiquement destinées à favoriser le « retour à l’emploi » des artistes précaires. Bien que cette prise en charge spécifique soit politiquement légitimée comme un soutien public aux créateurs précaires, les résultats d’une enquête de terrain au long cours permettent d’en révéler les contreparties du point de vue des usagers. En faisant des artistes une cible prioritaire de l’action publique d’insertion, ce traitement institutionnel différencié accroît le contrôle de la recherche d’emploi, tout en objectivant de façon stigmatisante leur insuccès professionnel. En définitive, si l’État social s’adapte aux artistes, c’est pour mieux les adapter en retour au marché de l’emploi.

Authors: Johnson Karmie M. , Patel Bela , Talley Michele H.
Published: April 2022

Background:

The use of an innovative approach for mental health interviews met unprecedented needs during the coronavirus disease 2019 pandemic for patients and staff at a community health clinic and provided nursing students with a telehealth activity that met patient care education requirements while practicing essential skills.

Method:

The nursing students and instructors worked collaboratively with the clinical team to call patients using an algorithm that incorporates screeners for depression, anxiety, and chronic disease distress.

Results:

Reports during daily debriefings and feedback obtained from evaluations were summarized by faculty and used to improve the activity. These reports indicated the experience was beneficial to students and clinic staff.

Conclusion:

Providers were able to follow up on vulnerable patients more quickly, students were able to practice essential nursing skills during a time when safety concerns limited direct patient interaction, and patients continued to feel connected to health care providers during a global pandemic.

Utility and Acceptability of a Peer Assessment Rubric to Improve Interprofessional Learning
Authors: Bybee Sara , Supiano Katherine , Wilson Rebecca
Published: April 2022

Background:

Peer assessment rubrics (PARs) facilitate equitable distribution of responsibility among group members and help educators assess learners' contributions. This study sought to (1) address health science students' attitudes toward group work and peer assessment, (2) apply evidence-based recommendations and student suggestions to the adaptation of a PAR, and (3) determine the rubric's effectiveness for educators and acceptability among students.

Method:

A PAR was identified, modified, and tested with graduate students (
N
= 502) in the health sciences.

Results:

Compared with prior PARs, graduate students rated this rubric as easier to use and more helpful in assessing peers' contributions and explaining their ratings. Educators reported the PAR's utility with diverse health science students across both in-person and virtual platforms.

Conclusion:

Using a PAR that is acceptable to students and useful for faculty may contribute to more meaningful interprofessional experiences, ultimately preparing students for effective interprofessional collaboration.

On the solvability of a semilinear higher-order elliptic problem for the vector field method in image registration
Authors: Zheng Xiaojun , Huan Zhongdan , Liu Jun
Published: April 2022

We study the existence of the solution to a semilinear higher-order elliptic system

   \begin{document}$ \mathcal{L}v(t, \cdot) = F_{S, T}\circ G(v)(t, \cdot), \quad \forall t\in [0, \tau], $\end{document}

with the homogeneous Dirichlet boundary conditions. Here, \begin{document}$ \mathcal{L} = (-\Delta)^m $\end{document} is a harmonic operator of order \begin{document}$ m $\end{document}, \begin{document}$ v = v(t, x):[0, \tau]\times\Omega\rightarrow \mathbb{R}^n $\end{document} is the unknown, \begin{document}$ t $\end{document} is a parameter, \begin{document}$ F_{S, T} $\end{document} is a function related to given functions \begin{document}$ S $\end{document} and \begin{document}$ T $\end{document}, and \begin{document}$ G(v)(t, x) $\end{document} is defined by the solution \begin{document}$ y^v(s;t, x) $\end{document} of an ODE-IVP \begin{document}$ {\rm d}y/\mathrm{d}s = v(s, y), \quad y(t) = x $\end{document}. The elliptic equations is the Euler-Lagrange equation of the vector field regularization model widely used in image registration. Although we have showed the existence of a solution to this BVP by the variational method, we hope to study it by the fixed point method further. This is mainly because the elliptic equations is novel in form, and the method here put more emphasis on the quantitative analysis whereas the variational method focus on the qualitative analysis. Since the system here is a higher order semilinear system, and its nonlinear term is dominated by an exponential function with respect to the unknown, we use an exponential inequality to construct a closed ball, and then apply the Schauder fixed point theorem to show the existence of a solution under some assumptions.

Published: April 2022

This paper deals with the null controllability of the semilinear heat equation with dynamic boundary conditions of surface diffusion type, with nonlinearities involving drift terms. First, we prove a negative result for some function \begin{document}$ F $\end{document} that behaves at infinity like \begin{document}$ |s| \ln ^{p}(1+|s|), $\end{document} with \begin{document}$ p > 2 $\end{document}. Then, by a careful analysis of the linearized system and a fixed point method, a null controllability result is proved for nonlinearties \begin{document}$ F(s, \xi) $\end{document} and \begin{document}$ G(s, \xi) $\end{document} growing slower than \begin{document}$ |s| \ln ^{3 / 2}(1+|s|+\|\xi\|)+\|\xi\| \ln^{1 / 2}(1+|s|+\|\xi\|) $\end{document} at infinity.
Pinning detectability of Boolean control networks with injection mode
Authors: Mu Tiantian , Feng Jun-E , Wang Biao
Published: April 2022

This technical note presents analytical investigations on detectability of Boolean network with pinning control and injection mode (BNPCIM). Detectability represents the property to uniquely determine the current state of the system according to known input-output sequences. Using Cheng product of matrices, BNPCIM can be converted into a special algebraic form of BCNs with mix-valued logical control. Based on different research requirements, three types of detectability for BNPCIM are proposed: weak detectability, detectability and strong detectability. Under free and networked input conditions, a sequence of matrices are constructed to reflect output and state information by explicit forms. Then by using the established matrices, several necessary and sufficient conditions for three types of detectability are derived. Moreover, to avoid unnecessary calculations, the maximum steps to achieve different detectability are gained. Finally, two illustrative examples are given to demonstrate the effectiveness of the obtained results.
Visual Methodologies and Geography's education in the pandemic time: notes on geopolitics of migration in the "Mediterranean Complex"
Authors: Palermo Gabriella
Published: April 2022

The relationship between Geography and the Visual has always been strong intertwined. As it is true that Geography has always operates through images (in the form of pictures, creative representations and above all cartographies), in the last two years, with the distance learning due to the spread of the Covid-19 pandemic, this phenomenon has not only increased, but it also became necessary. "The classroom as the most radical space", in the words of bell hooks, had to turn into a virtual space, where images have a fundamental role in the teaching/learning process. This paper wants to analyse the relationship between Geography and the Visual by analysing three images we used in the lessons of the course Geopolitics of Migration at the University of Palermo during the academic year 2020–2021, that speak about the "Mediterranean Complex". With this expression, inspired by Mirzoeff's work, I will briefly focus on the clash between dominant visuality and the counter-visualities emerging from the Mediterranean Sea, a particular sea-space where on the one hand, violent geopolitics daily act against migrants' crossing; on the other hand, new imaginative geographies emerge against coloniality devices of power and knowledge. A further reflection will be dedicated to the use of these images as a didactic tool. Why do we use these images? What do they tell us? Which one is the relationship between our increasingly digital classrooms and these images? If it is true that the pandemic phenomenon is acting as a laboratory of experimentation and acceleration, how is the visual nature of geography changing and participating to the construction of our knowledge? This contribution is a first attempt to reflect about those questions through the visuality and the counter-visualities of the "Mediterranean complex".
On the impact of the Covid-19 health crisis on GDP forecasting: An empirical approach
Authors: Illanes Gabriel , Mordecki Ernesto , Sosa Andrés
Published: April 2022

Statistical dependence between the GDP growth projection adjustments for the end of 2020 and the health impact of the Covid-19 pandemic is detected and quantified for a broad set of countries. A \begin{document}$\texttt{rate }$\end{document} that captures this health impact for each country is contrasted to the difference in GDP growth projections for the end of 2020 released in two subsequent times: 2019 (pre-pandemic) and early 2020 (post-pandemic). The difference of this two variables exhibited a significant rank correlation with the \begin{document}$\texttt{rate }$\end{document}, and a linear model was successfully fitted, concluding that at the beginning of the pandemic health conditions played a significant role in the GDP projections.
De tumba a iglesia. Análisis arqueológico y arquitectónico del complejo funerario del Reino Antiguo (QH34h) y su transformación en iglesia cristiana bizantina en la necrópolis de Qubbet el Hawa (Asuán, Egipto)

Published: April 2022

El yacimiento arqueológico de Qubbet el-Hawa alberga una de las mayores necrópolis del sur de Egipto. En ella se enterraron los altos dignatarios y los nobles que gobernaron la provincia más meridional de Egipto desde el Reino Antiguo (al menos la VI dinastía) hasta el Reino Medio (Dinastía XII). Se han llegado a documentar más de 70 hipogeos, alguno de los cuales aún siguen sin ser investigados en profundidad. El trabajo que aquí presentamos trata de comprender uno de los complejos funerarios más grandes y antiguos de la necrópolis, compuesto por la tumba conocida como QH34h, que perteneció al gobernador Khunes y las tumbas anexas de sus familiares. Fue construido hacia el final del reinado de Pepy II (2216-2153 a. C.), sufrió una serie de transformaciones arquitectónicas a lo largo de su historia, derrumbes importantes y finalmente fue elegido por una comunidad monástica para establecer en él una iglesia cristiana en el siglo VI. El objetivo principal de este artículo es analizar cómo un espacio sagrado cambió a lo largo del tiempo y los diferentes espacios arquitectónicos fueron usados en diferentes propósitos.

Études sur Spinoza et les philosophies de l’âge classique
Authors: Matheron Alexandre
Published: April 2022

Les travaux d’Alexandre Matheron sur Spinoza et sur les philosophies de l’âge classique représentent un des points forts de l’école française d’histoire de la philosophie. Après Individu et Communauté chez Spinoza et Le Christ et le salut des ignorants, les études réunies ici complètent la vision du spinozisme et de son contexte, de ses racines et de sa signification historique. Elles traitent de tous les domaines du rationalisme classique : métaphysique, théorie de la connaissance, analyse des passions, éthique, politique et religion.

La méthode qui anime ces textes est celle d’une analyse structurale de la pensée philosophique : il s’agit de prendre au sérieux le caractère conceptuel des doctrines, leurs enchaînements argumentatifs, la rigueur et la cohérence de leurs catégories. Mais la considération de l’architecture d’un monument théorique ne se conçoit pas sans la biographie non de l’auteur mais de l’œuvre : comment Spinoza est devenu Spinoza ; en d’autres termes, comment il a forgé sa pensée en traversant les arguments et les concepts de Machiavel, de Hobbes ou de Descartes pour arriver à des formulations de plus en plus spinozistes de son ontologie de la puissance. Le rationalisme absolu apparaît ainsi non seulement comme contenu des pensées étudiées mais aussi comme méthode d’histoire de la philosophie.

Une démarche qui a donné des outils intellectuels à plusieurs générations de chercheurs et qui indique aujourd’hui le chemin pour pénétrer dans l’univers de la pensée classique. La seule façon rigoureuse de nous demander ce qui pour nous, de ces philosophies, est vrai.
L’hypothèse de l’acculturation dans le processus de néolithisation : approche logiciste de quelques exemples

La néolithisation, c’est-à-dire l’ensemble des processus par lesquels une société évolue vers le Néolithique, est un phénomène complexe mettant en œuvre de multiples paramètres et variables. En Europe occidentale, sa diffusion progressive vers l’ouest à partir d’un foyer proche oriental met également en jeu toute une variété de scénarios locaux, en lien notamment avec les milieux rencontrés, tant naturels qu’humains. De ce dernier point de vue, il faut donc prendre en compte le fait que cette expansion du Néolithique eut lieu dans des espaces déjà occupés par les chasseurs cueilleurs mésolithiques, et que de nombreux contacts durent avoir lieu. Force est toutefois de constater que les mésolithiques ont finalement disparus, plus ou moins rapidement, sur l’ensemble de cet espace. Les modalités de ce bouleversement restent délicates à identifier, et peuvent faire appel à tout un panel de scénarios. Faute de traces d’extermination massive des derniers mésolithiques par les colons néolithiques, un processus d’acculturation des uns par les autres constitue une hypothèse probable à la base de plusieurs des modèles qui ont pu être construits. Cependant, et de façon très générale, l’acculturation d’un groupe par un autre nécessite a minima une proximité géographique et chronologique des deux acteurs, condition qui n’est pourtant que très rarement explicitée. Par ailleurs, il est également nécessaire de pouvoir démontrer l’existence d’un tel processus d’un point de vue archéologique, comme identifier des vestiges matériels susceptibles de l’illustrer. Dans cet article, nous allons ainsi examiner plusieurs de ces scénarios et discuter leurs construction par le moyen d’analyses logicistes, méthode où chaque argument avancé par les auteurs et chacune des inférences déduites sont bien spécifiés et mis en relation les uns avec les autres, autorisant ainsi à tester la fiabilité et la cohérence desdits scénarios. Nous examinerons ainsi des hypothèses développées en Italie du Nord, Sud de la France et Bassin rhodanien.
Le Rec de la Redouna 2: a site testifying to the “Second Mesolithic” of the North-Eastern piedmont of the Pyrenees
Authors: Baills Henry
Published: April 2022

The site of Le Rec de la Redouna 2 is located in the eastern part of the Corbieres limestone massif, a karst landform in the southernmost part of France. The open air site was discovered in 2015, during fieldwalking on a flat terrace of a natural rock spur at the confluence of two creeks. Lithic raw materials used at Le Rec de la Redouna 2 site were flints from Oligocene-Miocene deposits in the the Bages-Sigean basin, located 41 km as the crow flies to the north-east. The knappers used punch percussion techniques to obtain thin rectilinear bladelets that were found in significant numbers. Despite a limited number of diagnostic pieces, the lithic industry of Le Rec de le Redouna 2 can be culturally connected with the “Second Mesolithic” as defined in the Corbieres mountains and more widely in Southern France. This temporal and cultural classification is based on the presence of geometrical microliths with abrupt truncations, mainly trapezes, which are markers of that period in the north-eastern part of the foothills of the Pyrenees. The remainder of the lithic artifacts are ubiquitous and are comprised of small end-scrapers and Montbani-type retouched bladelets. The site of Le Rec de la Redouna 2 increases our knowledge regarding the characteristics of human settlement during this period of the Holocene. It makes it possible to highlight anthropic choices. Thus, its localization at the confluence of two permanent creeks, in a flat zone with soft ground, (well exposed to sunshine and protected from the prevailing winds), provides us with many parameters that make it possible enhance our understanding of the living conditions and motivations of Late Mesolithic hunters with regard to their strategies of spatial occupation. Currently, the presence of a Late Mesolithic period evidenced in the Eastern Pyrenees provides a very important information for further research into how late hunters were systematically organised when it came to identifying these open-air sites with such singular topographical locations.
Modélisation de l’extinction de Néandertal
Authors: Ouvrard Louise , Degioanni Anna
Published: April 2022

Les Néandertaliens, au cours de leur existence, occupent un vaste territoire compris entre l’Europe et l’Asie. Leur extinction plutôt rapide coïncide avec l’arrivée des Hommes anatomiquement modernes (HAM) en Europe. Même si les causes de l’extinction des Néandertaliens ne sont pas aujourd’hui établies, un grand nombre d’hypothèses existent, celle privilégiée est l’entrée en compétition pour les ressources des HAM avec les Néandertaliens, ces derniers étant désavantagés face aux nouveaux arrivants.Nous utilisons la modélisation afin de comprendre le « fonctionnement » de la démographie des Néandertaliens au cours des 15 000 ans qui précèdent leur extinction.Nous proposons différents scénarios, testés en utilisant les données issues de la littérature scientifique.Les résultats nous indiquent que Néandertal aurait survécu, et donc que ces scénarios ne sont pas « vraisemblables ». Dès lors, soit les scénarios n’ont pas été correctement construits, soit les valeurs utilisées ne sont pas assez proches de la réalité. Nous avons donc choisi d’identifier les valeurs des paramètres démographiques (fertilité et mortalité) qui auraient pu déterminer l’extinction des Néandertaliens. Nous nous apercevons que pour que Néandertal disparaisse en 15 000 ans, il est nécessaire que sa fertilité baisse et que sa mortalité augmente fortement. L’arrivée de l’HAM ne semble pas être le seul facteur capable d’influer sur la dynamique des Néandertaliens.
L’écologie quantifiée. Essai de description de l’environnement continental à l’aide des microvertébrés
Authors: Jeannet Marcel
Published: April 2022

Face à l’insuffisance des données isotopiques (18O/16O) sur le domaine continental, la méthode de l’écologie quantifiée tente de combler cette lacune à l’aide des microvertébrés. Les données de base sont présentées en annexe pour 145 espèces eurasiatiques et 450 stations météorologiques du même espace, offrant chacune 15 paramètres climatiques trentenaires. La technique de traitement des données est présentée sous forme d’un mode opératoire facilitant son emploi pour l’élaboration des graphiques. Des exemples de résultats sont donnés pour chacun des paramètres d’un même site. Les exemples suivants concernent strictement l’évolution de la moyenne des températures annuelles dans quatre gisements couvrant la fin du Pléistocène moyen et presque entièrement le Pléistocène supérieur. La courbe est comparée à des sites contemporains traités par d’autres méthodes. Un dernier diagramme retrace la synthèse du cheminement de la courbe et la compare à la courbe 18O/16O de Martinson (Martinson et al. 1987) portant sur les bryozoaires des fonds marins des cinq océans. Enfin, différents traitements sont proposés par transposition des formules des climatologues et concernent la continentalité, la pluviométrie, l’aridité et le confort mais elles ne sont pas développées.
Caractérisation chronoculturelle du mobilier funéraire en Provence au Néolithique final et au Bronze ancien
Authors: Sauzade Gérard
Published: April 2022

Les trois périodes principales d’utilisation ou de réutilisation des sépultures collectives, le Néolithique final I, II et le Bronze ancien sont difficiles à dissocier dans les tombes dont les contenus ne sont pas distincts en général. Il est donc essentiel de rechercher des sépultures de référence où le remplissage est chronologiquement homogène afin d’acquérir un référentiel du mobilier spécifique à chaque période en vue de l’appliquer à l’étude des tombes à utilisation longue. Cette approche peut permettre de mieux appréhender l’évolution de pratiques funéraires qui ont perduré pendant près de 1500 ans.
Le Sud-Est de la France entre 4400 et 3400 avant notre ère. Sériation céramique et outillage lithique
Authors: Willigen Samuel van , D’Anna André , Renault Stéphane , Sargiano Jean-Philippe
Published: April 2022

Ces dernières décennies, notre connaissance du Néolithique moyen du quart sud-est de la France a considérablement évolué. Ceci est lié au renouvellement profond des méthodes d’étude et des sources documentaires. Les avancées, dues en grande partie à la mise en place de l’archéologie préventive dans des régions jusque là peu touchées par ce genre de travaux, mettent en évidence la nécessité d’une vision critique des schémas évolutifs du Néolithique moyen méditerranéen en même temps qu’elles la permettent. Ce travail ne peut être mené à bien qu’en mettant de côté des concepts mis en place à une époque où les bases documentaires n’avaient rien en commun avec celles dont nous disposons actuellement.
Comment la dépression vint aux singes
Authors: GERBER Lucie
Published: April 2022

Peut-on substituer l’animal à l’humain pour étudier le trouble mental ? À la fin des années 1960, le psychologue Harry F. Harlow de l’université du Wisconsin a formé le projet de modéliser, chez le singe, la dépression comme un trouble motivé par des chocs externes, se manifestant par une perturbation de la vie sociale. En retraçant les origines, les voies techniques et la marche de ce projet de psychopathologie expérimentale au cours des années 1970, et en confrontant ses ambitions à la récalcitrance des singes, cet article examine les ressorts de la fragilité des modèles animaux de troubles mentaux.

À quels signes reconnaît-on un fou ? Les psychiatres disent : il n’y a rien de plus simple à reconnaître qu’un fou. Mais ils disent aussi qu’il n’y a rien de plus compliqué à reconnaître, et que c’est pour cela qu’ils ont besoin de beaucoup d’expérience et des subtilités de l’art clinique. Qu’y a-t-il donc dans ce regard ambivalent ? De quoi est fait le savoir clinique ?
La mémoire multivers
Authors: ELLIOTT Denielle
Published: April 2022

Quelle est la texture de la temporalité, et comment savons-nous ce qui est réel, irréel, une hallucination, un souvenir, une confabulation ? L’article explore les expériences sensorielles inhabituelles associées aux lésions cérébrales traumatiques, les imaginations apparemment irrationnelles d’êtres apparemment rationnels. Le « jamais vu » et le « déjà vu » – expériences sensorielles associées à des troubles neurologiques résultant d’une lésion ou d’une épilepsie – sont des expériences mnésiques, lorsque l’organique et le psychique sont indiscernables. Elles sont vécues comme des troubles de la mémoire, impliquant le jeu du temps, brouillant le fantasme et la réalité. Ces troubles sont vécus par la narratrice et son autre moi, confondant l’esprit, subvertissant l’espace et le temps.
Un gigantesque zoo vertical
Authors: FITZGERALD Des
Published: April 2022

Comment se fait-il que lorsque nous voyons des images de nouveaux aménagements urbains majeurs aujourd’hui – qu’il s’agisse de logements, d’immeubles de bureaux ou de centres commerciaux – ces aménagements ont toutes les chances d’être revêtus d’un mince couvert d’arbres ? L’idée que les villes seraient mauvaises pour les êtres humains, et en particulier pour notre santé mentale a une longue histoire. De Shanghai à Paris, de la biophilie à la « nature bon marché », de Donna Haraway à Thomas Heathwick, j’examine l’intrication croissante entre la ville psychologiquement réparatrice et la ville verte. Pourquoi demandons-nous aujourd’hui à nos espaces urbains, refondus en centres de nature et de vie biologique, d’avoir une relation réparatrice avec la santé mentale ?
Entraîner les cerveaux schizophréniques
Authors: MOUTAUD Baptiste
Published: April 2022

Le développement de méthodes d’entraînement cognitif pour la schizophrénie illustre la place prépondérante prise par les neurosciences dans la psychiatrie contemporaine. Dans cet article je décris comment ces pratiques orientent et modèlent les conceptions du soin et des troubles mentaux, et en particulier les représentations de l’entremêlement des causalités sociales, psychologiques et biologiques de la schizophrénie. D’abord en faisant émerger une représentation du corps des malades comme perméable et sensible à son environnement social et matériel ; puis en mobilisant une conception du cerveau comme organe plastique support d’un idéal d’émancipation et d’autonomisation. Enfin, je montre enfin comment cette pratique devient pour ses promoteurs un outil d’insertion sociale et professionnelle.
Excess in the avant-garde of the data subject
Authors: CARR Danielle
Published: April 2022

Although quantification has marked psychiatric practice since the rise of experimental psychology, the past two decades have seen an intensified use of data, implemented in tandem with a general move toward big data and “scored societies” across the biosciences. Today, a new, hyper-quantified psychiatry is aiming to map the neurological substrates of affective disorder through extracting neural data from brain implants. The classic story that is often rendered by many critical scholarly accounts about this new form of hyper-quantified psychiatry is that in their drive to render psychiatry profitable to new forms of data capitalism, such technologies evaporate language and the subjective into a cascade of numbers. This paper examines a case study of a subject enrolled in an experimentation in psychiatry for the first brain implant system coupled to an artificial intelligence in order to trouble such easy narratives about quantification. How would our account of quantification change if we saw language not as an extraneous surplus to the experimental production of numbers, but at the heart of how these new technologies of quantification are being developed?
Psychiatric patients at work
Authors: EDINGTON Claire
Published: April 2022

In colonial Vietnam, mental asylums were designed as large agricultural colonies, where patients would work the land on the path to healing and eventual liberation. This article discusses the role of labor as a kind of therapy for asylum patients, and how French psychiatric experts were constantly drawn into broader networks of care and economy, thereby shifting attention from the asylum itself to the world beyond its walls.
