Dar a luz y llegar al mundo desde casa: colisión de intereses jurídicos entre la madre y el nasciturus
Authors: Gil Gómez Olga
Published: December 2023

El Tribunal debe resolver sobre la constitucionalidad de la orden de ingreso hospitalario de una gestante para el control de la etapa final del embarazo y, en su caso, la inducción del parto, a razón de un aumento del riesgo de muerte fetal intrauterina. Se trata de una decisión contraria a su voluntad de llevar a cabo un parto domiciliario. Este contexto pone de manifiesto la existencia de un conflicto entre los derechos fundamentales de la mujer a la libertad personal y a la intimidad personal y familiar y de un bien constitucionalmente protegido, la vida y la salud del nasciturus. Su solución resulta en la limitación de los derechos de la gestante, aun sin haberle otorgado trámite de audiencia. Ello recibe el respaldo del Tribunal Constitucional por tratarse de una medida con fundamento legal, proporcional al fin de protección perseguido y justificada en una situación de extrema urgencia.

The research relevance is determined by the increasing role of artificial intelligence in the tourism business, which was demonstrated during the outbreak of the COVID-19 pandemic in Bali, resulting in a decline in the number of tourists visiting the island. The research aims to investigate the real-life experience of applying artificial intelligence systems in the tourism industry to address the challenges of developing the tourism industry in Bali, Indonesia. The basis of the methodological approach is a combination of theoretical methods of analysis and synthesis of the collected information covering the practical experience of the application of artificial intelligence systems in the tourism industry, as well as a survey of customers of travel agencies that have used such systems in trips to Bali. The research results show that artificial intelligence can significantly help the tourism business in Bali, as the number of tourists visiting the island dropped by 40% during the pandemic, resulting in a reduction in the number of tourism staff. The practical application of systems based on artificial intelligence opens up a wide range of business opportunities, as it allows for optimizing the activities of tourism firms and providing customers with high-quality services with highly technical equipment. The use of neural network mathematical models of tourist firms’ activity based on AI, allows them to achieve high speed of data processing, which allows tourist firms numerous competitive advantages and significantly improves the quality of their services. The practical significance of the results of this scientific research lies in the possibility of their application in the organization of the activities of enterprises in the sphere of tourism business, built on the use of digital technologies and systems based on artificial intelligence.

Flexible Architectural Interventions for Housing Issues in Bahrain
Authors: Seddiq Fatema , Al Khalifa Fay
Published: December 2023

Houses are important to every living creature they are considered the center of our universe and our haven. Recently having a home that reflects the identity and fulfills the desires of the occupants became a challenge due to the lack of space due to overpopulation in the world, especially in areas with small surface area compared to population size like the island of Bahrain. The unaffordability of housing and lack of space pushed most governments to start producing social houses with design limitations and bulk production. This paper aims to identify the problems related to social housing in Bahrain and seeks the possibility of using flexible architectural interventions to solve these issues. Interviews are conducted with Bahraini families living in social housing projects to identify their issues and their thoughts about flexible solutions. The results show that almost all social housing occupants are not satisfied with their houses' spatial design and have made costly modifications. They also lack the knowledge of flexible interventions and refuse them as a solution while encouraging the idea of vertical housing. This study introduces the term flexibility in social housing and emphasizes the need to improve occupants’ satisfaction in Bahraini society by using efficient architectural interventions.
Phytobiotics: Response to Aquaculture as Substitute of Antibiotics and other Chemical Additives
Authors: Bhanja Avik , Payra Pijush , Mandal Basudev
Published: December 2023

The use of phytobiotics in aquafarming is nowadays an interesting topic because of its eco-friendly nature for the growth and antimicrobial performance of aqua livestock. Currently, the use of various antibiotics in aquaculture are restricted due to concerns about the potential development of antibiotic-resistant pathogenic bacteria. Overuse of antibiotics and other chemicals (like different disinfectants, chemicals, and preservatives) increases the potentiality of residual antibiotics and other chemicals being present in fish, fish flesh as well as in fishery products. Various phytobiotics from plant extracts or direct plant or animal resources have changed the present traditional scenario of using an antibiotic component against livestock performance in aquaculture. The bioactive compounds (like alkaloids, tannins, saponins, glycosides, terpenoids, phenolics, flavonoids, essential oils, or steroids) present in the phytobiotics act as an immunity booster, growth promoter, bio-appetizer, reproductive stimulator, bio-preservatives, etc. So, phytobiotics becoming an effective additive in aquaculture as a substitute for antibiotics and other chemical components. This present article is designed to provide a comprehensive and insightful overview of the current state of knowledge about phytobiotics that supports the need for sustainable and environmental friendly practices in the context of aquaculture.

days, and the post-peak light curves also decline at a much faster pace relative to normal stripped-envelope supernovae (SNe) of Type Ib/Ic. The early-time spectrum of SN 2021agco (t ≈ 1.0 days after the peak) is characterized by a featureless blue continuum superimposed with a weak emission line of ionized C iii, and the subsequent spectra show prominent He i lines. Both the photometric and spectroscopic evolution show close resemblances to SN 2019dge, which is believed to have an extremely stripped progenitor. We reproduce the multicolor light curves of SN 2021agco with a model combining shock-cooling emission with 56Ni decay. The best-fit results give an ejecta mass of ≈0.3 M
⊙ and a synthesized nickel mass of ≈2.2 × 10−2
M
⊙. The progenitor is estimated to have an envelope radius of R
env ≈ 80 R
⊙ and a mass of M
env ≈ 0.10 M
⊙. All these suggest that SN 2021agco can be categorized as an ultra-stripped SN Ib, representing the closest object of this rare subtype. This SN is found to explode in the disk of a Sab-type galaxy with an age of ∼10.0 Gyr and low star-forming activity. Compared to normal SNe Ib/c, the host galaxies of SN 2021agco and other ultra-stripped SNe tend to have relatively lower metallicity, which complicates the properties of their progenitor populations.

The nonlinear evolution of Alfvén waves in the solar corona leads to the generation of Alfvénic turbulence. This description of the Alfvén waves involves parametric instabilities where the parent wave decays into slow mode waves giving rise to density fluctuations. These density fluctuations, in turn, play a crucial role in the modulation of the dynamic spectrum of type III radio bursts, which are observed at the fundamental of local plasma frequency and are sensitive to the local density. During observations of such radio bursts, fine structures are detected across different temporal ranges. In this study, we examine density fluctuations generated through the parametric decay instability (PDI) of Alfvén waves as a mechanism to generate striations in the dynamic spectrum of type III radio bursts using magnetohydrodynamic simulations of the solar corona. An Alfvén wave is injected into the quiet solar wind by perturbing the transverse magnetic field and velocity components, which subsequently undergo the PDI instability. The type III burst is modeled as a fast-moving radiation source that samples the background solar wind as it propagates to emit radio waves. We find the simulated dynamic spectrum to contain striations directly affected by the multiscale density fluctuations in the wind.
Day–Night Transport-induced Chemistry and Clouds on WASP-39b: Gas-phase Composition
Authors: Tsai Shang-Min , Moses Julianne I. , Powell Diana , Lee Elspeth K. H.
Published: December 2023

JWST has recently detected the first robust photochemical product on an exoplanet: sulfur dioxide (SO2) on WASP-39b. The data from the NIRISS instrument also reveal signs of partial coverage of clouds. Most of the previous studies have focused on interpreting spectral data with 1D models. To explore how the chemical species and cloud particles are altered by global circulation, we applied a 2D photochemical model and a 2D microphysical cloud model separately to postprocess the thermal and dynamical structures simulated by a 3D general circulation model of WASP-39b. We found that SO2 produced by photochemistry on the dayside can be transported to the nightside owing to the efficient replenishment of horizontal transport. The morning–evening limb differences in methane (CH4) abundances predicted by the 1D models disappeared after horizontal transport is included. Similarly, the inclusion of horizontal transport also reduced the limb differences in SO2. Our modeling results suggest that the fast zonal wind results in minimal or negligible limb asymmetry in composition. Based on the synthetic spectra generated by our 2D atmosphere simulations, we propose that observing SO2 absorption in the emission spectra of WASP-39b at different phases may offer opportunities to probe the horizontal quenching process of photochemical products. We will focus on the gas-phase chemistry in this paper and leave the results regarding clouds in the subsequent paper as part of the series.
Ce que l’ordinaire fait aux concepts philosophiques
Authors: Boldrini Miranda
Published: December 2023

Cet article interroge la relation entre réflexion philosophique et terrain de l’ordinaire en se concentrant sur l’usage et l’analyse des concepts dans le domaine de l’éthique philosophique. Dans un premier temps, à travers l’analyse de trois cas, nous explorons la manière dont l’ordinaire peut amener à remettre en question certains concepts philosophiques. Dans un second temps, nous nous interrogeons sur le type de réflexion philosophique conceptuelle qui peut se révéler fructueux pour l’analyse de l’ordinaire. En nous appuyant sur des auteurs de l’éthique wittgensteinienne (Diamond, Cavell), nous examinons l’opposition entre deux modèles d’analyse conceptuelle, en mettant en lumière leurs implications pour l’éthique philosophique et leur relation avec le terrain de l’ordinaire.
Économie circulaire et gestion des déchets ménagers : quelle dynamique de champ portée par les collectivités locales ?
Authors: Cristofini Olivier
Published: December 2023

La littérature en management s’est largement emparée des évolutions de pratiques induites par l’économie circulaire. Cependant, ces évolutions sont le plus souvent étudiées à l’échelle de l’organisation, laissant peu de place à la compréhension des changements opérant dans des systèmes sociaux plus larges – spécifiquement au sein des champs organisationnels. En réponse à ce constat, cet article interroge l’évolution d’un champ organisationnel liée à l’avènement de l’économie circulaire. Prenant pour cas l’adoption de la minimisation des déchets ménagers dans cinq territoires en France, il offre une analyse qualitative portant sur 32 entretiens associés à des observations et données secondaires. Cette analyse révèle une dynamique de recomposition du champ autour de pratiques d’économie circulaire à travers (1) l’alignement de ces pratiques sur les intérêts des acteurs centraux du champ (2) l’enrôlement dans ces pratiques d’acteurs jusqu’alors périphériques et externes au champ (3) une restructuration du champ à travers la stabilisation des rôles et des ressources en présence. Sur le plan théorique, ces résultats contribuent à une meilleure compréhension d’une dynamique de champ organisationnel portée par des acteurs publics locaux dans un contexte de changement de réglementation. Sur le plan managérial, cet article offre des éléments de stratégie aux collectivités territoriales souhaitant faire évoluer leurs pratiques de gestion des déchets ménagers dans le sens d’une économie circulaire.
Dettonville et les données
Authors: Maronne Sébastien
Published: December 2023

J’étudie la théorie des données proposée par Pascal dans les Lettres de A. Dettonville en la comparant aux Données d’Euclide éditées en 1625 par Claude Hardy. J’analyse en particulier la nouvelle définition de « raison donnée ou connue » dans laquelle Pascal considère la raison de la circonférence d’un cercle à son rayon. J’examine ensuite l’usage qui est fait par Pascal de la syntaxe des données dans les Lettres de A. Dettonville , au niveau global et au niveau local, pour analyser et résoudre les problèmes portant sur la roulette sans effectuer tous les calculs.
Some Thoughts on Pascal’s and Galileo’s “Indivisibles” and the Infinite Divisibility of Extension
Authors: Malet Antoni
Published: December 2023

Nous analysons la manière dont Blaise Pascal comprend le thème classique de la divisibilité infinie de l’extension (DIE). Nous montrons le rôle qu’elle joue dans la présentation pascalienne des « indivisibles » et, plus généralement, dans ses résultats géométriques. L’article décrit le contexte de la pensée de Pascal en analysant comment la DIE avait été discutée par Marin Mersenne, Galilée et René Descartes. Dans ce contexte, les idées de Pascal sur la DIE et l’infini actuel sont revisitées, en les mettant en contraste avec les vues critiques exprimées par le chevalier de Méré (Antoine Gombaud).
Aristotle’s “Greatest Difficulty”: Universality of Thought in Metaphysics M 10 and Θ 9
Authors: Roreitner Robert
Published: December 2023

Métaphysique M 10 est le seul endroit où Aristote fournit une solution à la “plus grande difficulté” du Livre B: si les principes des substances sont particuliers, mais que les objets de la connaissance scientifique doivent être universels, comment peut-il y avoir une connaissance scientifique de ces principes? Aristote répond que, en un sens important, la connaissance scientifique porte sur des choses particuliers. L’article montre pourquoi cette solution ne compromet pas le compte rendu officiel d’Aristote sur la connaissance scientifique, ni n’assimile la connaissance scientifique à la perception, ni ne présuppose une conception sophistiquée des formes (comme étant soit particulières en elles-mêmes, soit neutres en ce qui concerne l’universalité et la particularité). La solution d’Aristote en M 10 peut plutôt être comprise dans le contexte de son analyse de la pensée géométrique en Θ 9. À différents moments, le géomètre doit choisir une actualisation particulière du potentiel inhérent à la figure concernée, mais il doit le faire d’une manière qui permette de saisir ce potentiel dans sa pleine universalité. L’article explore la promesse d’Aristote (le plus explicitement dans Sur la mémoire 1) de prendre l’interaction entre l’universalité et la particularité dans les diagrammes géométriques comme modèle pour la pensée scientifique en général.

Authors: Wu Yifan , Ai Xiaohui
Published: December 2023

In this paper, a stochastic Leslie-Gower model with Beddington-DeAngelis functional response driven by the Ornstein-Uhlenbeck process is studied. Some asymptotic properties of the solution of the stochastic Leslie-Gower model are introduced: the existence and uniqueness of the global solution of the model are demonstrated, the ultimate boundedness of the model is analyzed, the existence of the stationary distribution of the model is proven, and the conditions for system extinction are discussed. Finally, numerical simulations are utilized to verify our conclusions.

Published: December 2023

In this paper, we give a kind of strongly regular Cayley graphs and a class of codebooks. Both constructions are based on choosing subsets of finite fields, and the main tools that we employed are Gauss sums. In particular, these obtained codebooks are asymptotically optimal with respect to the Welch bound and they have new parameters.

A practical approach to computing Lyapunov exponents of renewal and delay equations
Authors: Breda Dimitri , Liessi Davide
Published: December 2023

We propose a method for computing the Lyapunov exponents of renewal equations (delay equations of Volterra type) and of coupled systems of renewal and delay differential equations. The method consists of the reformulation of the delay equation as an abstract differential equation, the reduction of the latter to a system of ordinary differential equations via pseudospectral collocation and the application of the standard discrete QR method. The effectiveness of the method is shown experimentally and a MATLAB implementation is provided.
Hidden chaotic mechanisms for a family of chameleon systems
Authors: Zhang Xue , Sang Bo , Li Bingxue , Liu Jie , Fan Lihua , Wang Ning
Published: December 2023

Chameleon chaotic systems are nonlinear dynamical systems whose chaotic attractors can transform between hidden and self-excited types by tuning system parameters to modify equilibrium points. This paper proposes a novel family of chameleon chaotic systems, which can exhibit three types of chaotic attractors: self-excited attractors with a nonhyperbolic equilibrium, hidden attractors with a stable equilibrium, and hidden attractors with no equilibrium points. Bifurcation analysis uncovers the mechanisms by which self-excited and hidden chaotic attractors arise in this family of chameleon systems. It is demonstrated that various forms of chaos emerge through period-doubling routes associated with changes in the coefficient of a linear term. An electronic circuit is designed and simulated in Multisim to realize a hidden chaotic system with no equilibrium points. It is demonstrated that the electronic circuit simulation is consistent with the theoretical model. This research has the potential to enhance our comprehension of chaotic attractors, especially the hidden chaotic attractors.
