MECHANISM OF THE RELATIONSHIP BETWEEN COMPOSITION AND STRUCTURE IN ORTHORHOMBIC MULTIFERROICS Eu1-xSrxMnO3 (x = 0; 0.15; 0.25)
Authors:   Institute of Metallurgy, Vedmid Larisa B. , Fedorova Olga M. ,   Institute of Metallurgy
Published: May 2023

The paper presents results of the study of the structure evolution in perovskite-like manganites Eu1–xSrxMnO3 (x = 0; 0.15; 0.25). The influence of chemical composition and temperature on the phase state of manganites is shown. It is established that the substitution of europium with strontium in the range 0  x  0.25 does not lead to the Jahn — Teller order-disorder transition (O'O). An increase in temperature in the range of 300–980 °C provokes an O'O transition, and with an increase in the concentration of strontium, the transition temperature decreases.

The dependence of the value of ∆G0n,f (the standard Gibbs free energy of Ruddlesden-Popper RPn phase formation) on the n-value in the series AO∙(ABO3)n (where A = Ca, Sr, Ba, La; B = Co, Ni, Ti, Zr, Hf) was analyzed using the thermodynamic data available in the literature. It is found that the value of ∆G01/n,f for all analyzed systems depends linearly on 1/n. The consequences of the existence of the linear dependence are analyzed from the point of view of carrying out the synthesis of the RPn phases. On the example of strontium-rare-earth cobaltites of the composition (SrxLn1-x)n+1СоnO3n+1 (Ln = Sm, Gd, Dy; n = 2, ), the possibility of obtaining RPn phases with a different character of the distribution of Sr/Ln cations over the A-positions of the crystalline lattice, stabilization conditions for new metastable phases (SrxLn1-x)3Со2O7-, which are absent in the phase diagrams in air, are given.

At present, the interest of analytical chemists in metal-containing nanocomposites has increased significantly. This is primarily due to the possibility of their application as optical sensors. The operation of such sensors is based on the phenomenon of surface plasmon resonance (SPR). The result of this study is the development of a new sensitive method for the determination of iodide ions based on the use of paper modified with silver nanoparticles (NPs). Iodides, oxidized under the action of special reagents, form molecular iodine, which is extracted by an air flow and transferred to a sensitive paper layer containing NPs. The interaction of NPs with iodine leads to traceable optical changes. The limit of detection (0.01 mg/L) and the range of determined concentrations (0.03–0.3 mg/L) of iodide ions were determined.

Although, frequently used in psychiatry, concepts like dissociation, psychosis, and trauma are hard to define. The international diagnostic classification systems, the DSM and the ICD, do not offer a consensus. Symptoms related to these disorders overlap, are often difficult to evaluate, and their history brings up more confusion. These symptoms are not only present in the general population, but also in a large palette of other disorders, and this makes the understanding of them very important for clinical practice. Oversimplifying the diagnostic assessments and theoretical understanding may cause error. Instruments used for evaluating dissociation may bring clarification, but these instruments have their advantages and disadvantages. Often, trauma is assessed during the clinical interviews, but its role is very hard to quantify. We can say it is important to have individualized approaches.

Burnout syndrome as an occupational disease is more and more present among the professions related to care and aid. It is very closely related to working conditions, but also to the dimensional component of personality. Certain personality traits may determine the choice of a profession, but at the same time, these traits may favor the occurrence of burnout symptoms. The present research identifies the dimensions of the personality and burnout that prevail at physicians and registered nurses professional categories, searching for dissimilarities and similarities. Although physicians and registered nurses suffer equally of burnout syndrome, they present similarities as regarding the dimensions of the personality but concerning the dimensions of the burnout they present dissimilarities.

Ground-based high-resolution spectroscopy (HRS) has detected numerous chemical species and atmospheric dynamics in exoplanets, most notably ultrahot Jupiters (UHJs). However, quantitative estimates on abundances have been challenging but are essential for accurate comparative characterization and to determine formation scenarios. In this work, we retrieve the atmospheres of six UHJs (WASP-76 b, MASCARA-4 b, MASCARA-2 b, WASP-121 b, HAT-P-70 b, and WASP-189 b) with ESPRESSO and HARPS-N/HARPS observations, exploring trends in eleven neutral species and dynamics. While Fe abundances agree well with stellar values, Mg, Ni, Cr, Mn, and V show more variation, highlighting the difficulty in using a single species as a proxy for metallicity. We find that Ca, Na, Ti, and TiO are underabundant, potentially due to ionization and/or nightside rain-out. Our retrievals also show that relative abundances between species are more robust, consistent with previous works. We perform spatially resolved and phase-resolved retrievals for WASP-76 b and WASP-121 b given their high signal-to-noise observations, and find the chemical abundances in each of the terminator regions are broadly consistent. We additionally constrain dynamics for our sample through Doppler shifts and broadening of the planetary signals during the primary eclipse, with median blueshifts between ∼0.9 and 9.0 km s−1 due to day–night winds. Furthermore, we constrain spectroscopic masses for MASCARA-2 b and HAT-P-70 b consistent with their known upper limits, but we note that these may be biased due to degeneracies. This work highlights the importance of future HRS studies to further probe differences and trends between exoplanets.

cm−2, which is predominantly found toward two of the four velocity components we observe toward TMC-1. We use this molecule as a proxy for constraining the gas-phase abundance of the apolar hydrocarbon 1,3-butadiene. Based on the three-phase astrochemical modeling code NAUTILUS and an expanded chemical network, our model underestimates the abundance of cyano-1,3-butadiene by a factor of 19, with a peak column density of 2.34 × 1010 cm−2 for 1,3-butadiene. Compared to the modeling results obtained in previous GOTHAM analyses, the abundance of 1,3-butadiene is increased by about two orders of magnitude. Despite this increase, the modeled abundances of aromatic species do not appear to change and remain underestimated by one to four orders of magnitude. Meanwhile, the abundances of the five-membered ring molecules increase proportionally with 1,3-butadiene by two orders of magnitude. We discuss the implications for bottom-up formation routes to aromatic and polycyclic aromatic molecules.

Comment répondre à la demande d’une famille de prendre en charge un des siens enfermé depuis des années chez lui, sans le contraindre, sans l’enfermer en « psy »? Toute une équipe a été amenée à co-construire une réponse « sur mesure » pour une famille à la destinée tragiquement unique. Le travail d’élaboration à plusieurs a permis de tisser un récit familial qui au-delà des apports théoriques de chacun prenait son origine dans une mythologie partagée par tous : l’ Odyssée . Notre patient devenant Ulysse, sa rupture familiale et intra-psychique devenant un voyage, nous changions de temporalité et étions prêts à rêver son retour à la vie. Dans la profondeur des strates de sa vie psychique, la relation thérapeutique a tiré le fil singulier de courriels à mots uniques ouvrant le lent processus de renaissance.
Se raconter dans le manque
Authors: Fourques Catherine
Published: May 2023

Comment se dire, se raconter si l’histoire ne se conjugue qu’à un seul temps sans savoir s’il s’agit du présent, du passé ou de l’avenir ? Quelle histoire de vie peut livrer une personne âgée malade d’Alzheimer et comment la transmettre lorsque la mémoire, la temporalité et les mots s’échappent ? Sans mésestimer la réalité de l’atteinte neuro-cognitive, l’attention portée sur la dimension affective et les autres modalités d’expression du langage, tel que le corps, se révèle précieuse et dit quelque chose de la qualité de l’investissement narcissique et objectal à partir desquels s’étaye la prise en charge. La redondance parfois contenue dans le discours décousu d’une personne âgée malade questionne sur la valeur de ces éléments répétitifs : indices précieux d’identité préservée ou au contraire signes d’identité figée menaçant une subjectivité fragile.

Quand la parole est gelée : accompagnement psychanalytique bref de la crise
Authors: Ferveur Christophe
Published: May 2023

La détresse psychique est une zone grise qu’il faut envisager comme la manifestation d’un processus de crise. Entre déséquilibre, potentiellement source de changements, et l’impasse avec son risque de rupture radicale, la crise agit avant tout comme le révélateur de conflits latents qui se dévoilent dans l’après-coup des grandes étapes de la vie. Indépendamment de l’organisation psychique, la déstabilisation que provoque la crise mobilise principalement les registres narcissiques et objectaux. Par la présentation d’un dispositif original, le Relais Étudiants Lycéens, quelques-uns des ressorts techniques d’un traitement psychodynamique bref et pluridisciplinaire seront envisagés comme un temps « intermédiaire » de traitement.

Published: May 2023

Depuis cinq ans, l’industrie automobile est entrée dans une transformation brutale, aussi rapide que profonde. Créé il y a deux ans, Stellantis a pour objectif de devenir une tech company de la mobilité durable. Son ambition : préserver la liberté de mouvement des citoyens au travers d’une offre propre, sûre et abordable. Les changements comportementaux montrent que le véhicule du futur doit réenchanter la mobilité que la voiture a permis de créer il y a plus d’un siècle… Il doit se positionner comme une réponse aux attentes des citoyens consommateurs et aux enjeux de mobilité durable. Ainsi, le véhicule du futur doit être considéré dans le cadre plus large de la mobilité de demain, en prenant en compte l’ensemble de la chaîne de valeur. Il doit dépasser la simple approche reposant sur les prestations produits en intégrant les attentes des consommateurs et en se conformant aux réglementations relatives à l’environnement, en particulier celles concernant le réchauffement climatique, pour rester durable et accessible au plus grand nombre.

Faire entrer la France dans la seconde révolution automobile
Authors: Chatel Luc
Published: May 2023

L’industrie automobile fait face à une transformation historique qui bouleverse comme jamais la chaîne de valeur du secteur. Les industriels y sont pleinement engagés, au point que le secteur automobile, par le poids de ses investissements en R&D, apparaît aujourd’hui comme le premier moteur de l’innovation en France et en Europe. L’accélération réglementaire européenne, à travers le paquet « Fit for 55 » qui fait du 100 % électrique la technologie unique dès 2035, implique cependant des risques pour le tissu industriel et pour l’emploi, qui plus est sur fond de repli sans précédent d’un marché impacté par une addition de crises. Y faire face en les transformant en opportunités, suppose trois leviers que mobilisent, d’ores et déjà, les industriels : reconquérir notre souveraineté technologique, réduire nos risques de dépendance et faire de la bataille de la compétitivité le levier majeur d’une nouvelle ambition industrielle. Or, au regard de son électricité décarbonée qui constitue un véritable avantage comparatif, la France est plus que jamais légitime pour se positionner comme le territoire prioritaire des investissements liés à l’électrification de la mobilité et pour en faire un levier de réindustrialisation.
L’Union européenne et la neutralité carbone des mobilités
Authors: Auverlot Dominique
Published: May 2023

Dans la suite de l’Accord de Paris, Ursula von der Leyen, présidente de la Commission européenne, a élevé au premier rang de ses priorités son ambition de faire de l’Europe le premier continent neutre en carbone à horizon 2050. Conjugué à la volonté de réduire les pollutions locales, cet objectif a conduit la Commission à prévoir l’arrêt de la vente des bus, des véhicules particuliers et des poids lourds émetteurs de gaz à effet de serre respectivement en 2030, en 2035 et (à 90 %) en 2040, tout en renforçant les normes d’émission des moteurs thermiques. Les textes correspondants, adoptés ou en cours de discussion, traduisent cette ambition souhaitable pour la survie de notre planète. Ils préfigurent cependant une transformation industrielle sans précédent de l’ensemble de la filière automobile. Celle-ci sera d’autant plus réussie qu’un dialogue de confiance existera ou plutôt se réinstaurera entre les acteurs de la filière, les États, la Commission et le Parlement européen, de façon à ce que les projets de règlements en cours de discussion et leurs révisions futures, qui devront intervenir aussi souvent que nécessaire, débouchent sur des décisions pragmatiques tenant compte tout à la fois de l’urgence climatique et de la capacité d’évolution des acteurs industriels. De plus, il est nécessaire que différentes mesures sociales et industrielles d’accompagnement non seulement des entreprises, mais également des femmes et des hommes et des territoires impliqués, soient effectivement mises en œuvre.
La robotique et l’intelligence artificielle au service de l’automobile

L’automobile doit se réinventer dans le contexte de la mutation des mobilités, qui s’accompagne d’une évolution très importante des systèmes de transport. En effet, l’information est au cœur des systèmes de transport intelligents qui sont en cours de déploiement : dès lors, comment la voiture doit-elle évoluer pour pouvoir y prendre toute sa place ? Dans cet article, nous souhaitons apporter un éclairage plutôt technique sur les transformations en cours. Tout d’abord, nous aborderons la connectivité : la voiture s’intègre dans le grand système qu’est l’Internet des objets, où elle produit aussi bien qu’elle consomme nombre d’informations. Ensuite, nous nous intéresserons à la robotisation, à l’autonomisation de la conduite : c’est un changement considérable qui entraîne la gestion de volumes considérables de données et leur traitement par de l’intelligence artificielle. Finalement, le tableau général est celui de l’intelligence : celle de nos sociétés qui doivent surmonter des défis considérables et, espérons-le, celle des systèmes que nous allons déployer pour y répondre, au sein desquels l’automobile devrait garder une place très importante.
Oil palm leaf ash's effect on the growth and yield of Chinese cabbage (Brassica rapa L.)
Authors: Damayanti Fitri , S Salprima Yudha , Falahudin Aswin
Published: May 2023

The production of Chinese cabbage (Brassica rapa L.) has not been able to keep up with consumers' demand. Appropriate application of fertilizers is a key element in boosting plant productivity. One of the problems faced when fertilizing is that plant nutrient uptake has low efficiency. The application of basic nitrogen–phosphorus–potassium (NPK) fertilizers is typically the main emphasis of traditional agriculture, whereas the need for micronutrients, including Si, receives less consideration. Organic and inorganic materials are sources of Si nutrients. Currently, organic materials include straw or rice husks. The use of oil leaf palm waste as a source of nutrients is relatively still rare. The oil palm leaf ash in the production of Chinese cabbage is still not yet been researched. This analysis aims to know the optimal of oil palm leaf ash for the growth and yield of Chinese cabbage. The growth parameters measured 40 days after planting: leaf number, plant height, crown diameter, and fresh weight were impacted by the usage of oil palm leaf ash. A combination of oil palm ash at a concentration of 3.75 kg/m2 and manure at a concentration of 1500 kg/m2 produced the greatest results. In general, the usage of oil palm leaf ash affected the growth of Chinese cabbage, but the results could not be statistically separated from the role of manure as a source of NPK for plants. It was also demonstrated that the use of oil palm leaf ash increased the resistance of Chinese cabbage to armyworms. Therefore, Si for agriculture it can be utilized from oil palm leaf ash as a natural source.

Output-based event-triggered control for discrete-time systems with three types of performance analysis
Authors: Choi Hyung Tae , Park Hae Yeon , Kim Jung Hoon
Published: May 2023

This paper considers an output-based event-triggered control approach for discrete-time systems and proposes three new types of performance measures under unknown disturbances. These measures are motivated by the fact that signals in practical systems are often associated with bounded energy or bounded magnitude, and they should be described in the $ \ell_{2} $ and $ \ell_\infty $ spaces, respectively. More precisely, three performance measures from $ \ell_{q} $ to $ \ell_{p} $, denoted by the $ \ell_{p/q} $ performances with $ (p, q) = (2, 2), \ (\infty, 2) $ and $ (\infty, \infty) $, are considered for event-triggered systems (ETSs) in which the corresponding event-trigger mechanism is defined as a function from the measured output of the plant to the input of the dynamic output-feedback controller with the triggering parameter $ \sigma (>0) $. Such a selection of the pair $ (p, q) $ represents the $ \ell_{p/q} $ performances to be bounded and well-defined, and the three measures are natural extensions of those in the conventional feedback control, such as the $ H_\infty $, generalized $ H_2 $ and $ \ell_1 $ norms. We first derive the corresponding closed-form representation with respect to the relevant ETSs in terms of a piecewise linear difference equation. The asymptotic stability condition for the ETSs is then derived through the linear matrix inequality approach by developing an adequate piecewise quadratic Lyapunov function. This stability criterion is further extended to compute the $ \ell_{p/q} $ performances. Finally, a numerical example is given to verify the effectiveness of the overall arguments in both the theoretical and practical aspects, especially for the trade-off relation between the communication costs and $ \ell_{p/q} $ performances.

Authors: Naeem Muhammad , Qiyas Muhammad , Abdullah Lazim , Khan Neelam , Khan Salman
Published: May 2023

Aggregation operators are the most effective mathematical tools for aggregating many variables into a single result. The aggregation operators operate to bring together all of the different assessment values offered in a common manner, and they are highly helpful for assessing the options offered in the decision-making process. The spherical fuzzy sets (SFSs) and rough sets are common mathematical tools that are capable of handling incomplete and ambiguous information. We also establish the concepts of spherical fuzzy rough Hamacher averaging and spherical fuzzy rough Hamacher geometric operators. The key characteristics of the suggested operators are thoroughly described. We create an algorithm for a multi-criteria group decision making (MCGDM) problem to cope with the ambiguity and uncertainty. A numerical example of the developed models is shown in the final section. The results show that the specified models are more efficient and advantageous than the other existing approaches when the offered models are contrasted with specific present methods.

Published: May 2023

In this paper, a class of systems of three-component coupled nonlinear fractional Schrödinger equations with general nonlinearities is investigated. Without any monotonicity condition and the Ambrosetti-Rabinowitz growth condition, we obtain some novel existence results of least energy solutions by using variational arguments and a Pohozaev manifold method.

Published: May 2023

The present paper aims to investigate the containment of nonzero central ideal in a ring $ \mathcal{R} $ when the trace of symmetric $ n $-derivations satisfies some differential identities. Lastly, we prove that in a prime ring $ \mathcal{R} $ of suitable torsion restriction, if $ \mathfrak{D}, \mathcal{G} : \mathcal{R}^n \rightarrow \mathcal{R} $ are two nonzero symmetric $ n $-derivations such that $ \mathcal{f}(\vartheta)\vartheta +\vartheta\mathcal{g}(\vartheta) = 0 $ holds $ \forall \; \vartheta \in \mathcal{W} $, a nonzero left ideal of $ \mathcal{R} $ where $ \mathcal{f} $ and $ \mathcal{g} $ are the traces of $ \mathfrak{D} $ and $ \mathcal{G} $, respectively, then either $ \mathcal{R} $ is commutative or $ \mathcal{G} $ acts as a left $ n $-multiplier. Finally, we characterize symmetric $ n $-derivations in terms of left $ n $-multipliers.
Bifurcation analysis of a reaction-diffusion-advection predator-prey system with delay
Authors: Bin Honghua , Duan Daifeng , Wei Junjie
Published: May 2023

A diffusive predator-prey system with advection and time delay is considered. Choosing the conversion delay $ \tau $ as a bifurcation parameter, we find that as $ \tau $ varies, the system will generate Hopf bifurcation. Then, for the reaction diffusion model proposed in this paper, we use an improved center manifold reduction method and normal form theory to derive an algorithm for determining the direction and stability of Hopf bifurcation. Finally, we provide simulations to illustrate the effects of time delay $ \tau $ and advection $ \alpha $ on system behaviors.

Published: May 2023

In this paper, the iterative learning control technique is extended to distributed parameter systems governed by nonlinear fractional diffusion equations. Based on $ P $-type and $ PI^{\theta} $-type iterative learning control methods, sufficient conditions for the convergences of systems are given. Finally, numerical examples are presented to illustrate the efficiency of the proposed iterative schemes. The numerical results show that the closed-loop iterative learning control scheme converges faster than the open-loop iterative learning control scheme and the $ PI^{\theta} $-type iterative learning control scheme converges faster than the $ P $-type and the $ PI $-type iterative learning control scheme.

Excess weight in adult life is an important risk factor for the development ofnoncommunicable diseases. On the other hand, aerobic physical exercise programs have beenshown to be important components both in the prevention and control of these conditions.This work aims to evaluate the effects of moderate intensity training on the body weight(BW) and food intake (FI) of adult male rats. Wistar rats were obtained at 30 days old.Throughout the experimental period, they were kept in appropriate cages (4 rats per box)containing food and water, temperature (22ºC) and photoperiod (07:00 to 19:00) controlled.At PN 40 they were divided into sedentary (S) and exercised (E) groups. The BW and FI weremeasured twice a week, from 40 to 140 days old. Exercised rats performed a moderate-intensity treadmill running from PN 90 to 120. During this period, they were submitted to aneffort test to evaluate performance and control the training load (55% to 65% VO 2max ). Theresults showed that both BW and FI were not altered with the training performed during adultlife, even after 20 days of exercise cessation. More studies are needed in order to assesswhether moderate-intensity training is able to attenuates the deleterious effects observed inthe biometric and metabolic markers of adult rats programmed for obesity and/or metabolicsyndrome.
Immune Dysfunction in Polycystic Ovary Syndrome
Authors: Banerjee Soma , Cooney Laura G , Stanic Aleksandar K
Published: May 2023

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive-aged individuals with ovaries. It is associated with anovulation and increased risk to fertility and metabolic, cardiovascular, and psychological health. The pathophysiology of PCOS is still inadequately understood, although there is evidence of persistent low-grade inflammation, which correlates with associated visceral obesity. Elevated proinflammatory cytokine markers and altered immune cells have been reported in PCOS and raise the possibility that immune factors contribute to ovulatory dysfunction. Because normal ovulation is modulated by immune cells and cytokines in the ovarian microenvironment, the endocrine and metabolic abnormalities associated with PCOS orchestrate the accompanying adverse effects on ovulation and implantation. This review evaluates the current literature on the relationship between PCOS and immune abnormalities, with a focus on emerging research in the field.

Published: May 2023

Osteogenic sarcoma is a high-grade tumor with greater preponderance for hematogenous metastasis. The most common sites for metastases are the lungs, bones, and lymph nodes. We present in this case report a 24-year-old man with recurrent high-grade osteogenic sarcoma of the right lower limb with serosal small bowel metastases and necrotizing enterocolitis. Sarcomas are high-grade tumors with an increased incidence of hematogenous metastases. Radiologists in oncological referral centers should be aware of the common as well as the uncommon presentation of all common tumors.

Authors: Li Lei , Liao Guangjie
Published: May 2023

Clinicopathological progress of dual-phenotype hepatocellular carcinoma (DPHCC) is a new subtype of hepatocellular carcinoma with poor prognosis. Immunohistochemistry plays a key role in the diagnosis of DPHCC. DPHCC is closely related to the mechanism of epithelial-mesenchymal transition and the stem cell characteristics of tumors. At present, there were few relevant literatures. We review the clinicopathological progress of DPHCC.
Statin use and risk of cancer
Authors: Kasana Ruby , Thomas Christy , Das Gaurav , Hazarika Munlima , Undela Krishna
Published: May 2023

BACKGROUND:

The relationship between statin use and cancer risk has been debated for a long time. Physiologically plausible theories suggest that statins may lower the risk of cancer. We have updated the overview of meta-analyses to include up-to-date information, additional subgroup analyses, and site-specific cancer risk estimates.

MATERIALS AND METHODS:

A systematic search was performed in the PubMed, Cochrane and Google scholar databases between June 2016 and December 2022. The search strategy included both statin- and cancer-related keywords. Meta-analyses examining the association between statin use and site-specific cancer risk were included. Two reviewers independently screened the literature, extracted data, and assessed the study quality using A MeaSurement Tool to Assess systematic Reviews 2 (AMSTAR 2) tool.

RESULTS:

This up-to-date overview included 71 meta-analyses (33 new and 38 from the previous overview) of 14 site-specific cancers. Out of which, 29 (44%) meta-analyses had a “Critically low” and three reviews (5%) had a “High” quality of evidence with AMSTAR 2. The pooled results of meta-analyses showed that statins reduce the likelihood of biliary tract (33%), colorectal (9%), gastric (29%), gynecological (12%), hematological (19%), liver (42%), esophageal (19%), and pancreatic (18%) cancers. However, no association was identified between statin use and the risk of bladder, breast, kidney, lung, prostate, and skin cancers.

CONCLUSIONS:

Statins may play a crucial role in cancer chemoprevention, reduce the risk of site-specific malignancies, and can be used as an adjuvant.
