The effect of the initial charge composition and the calcination temperature of a mechanically activated mixture of silicon, zirconium, and cerium oxides on the synthesis of solid solutions in compositions SiO2-хZrO2-0.1CeO2 (х = 0.9–1.2) has been studied. Mechanical activation was carried out in a centrifugal planetary mill AGO-2 for 10 min at a centrifugal factor of 40 g. The obtained mixtures were calcined in the temperature range 1200-1400 °C for 3 h. It has been shown that according to the X-ray phase analysis the synthesis products are Ce-containing zircon, Zr-containing cerianite, and Ce-containing tetragonal zirconia. Based on the content of these phases in the calcined samples calculated by the Rietveld method, the synthesis conditions corresponding to the most complete incorporation of cerium into the structure of zircon and tetragonal ZrO2 have been recommended.

The electrochemical behavior of rhenium-containing tungsten alloys waste of the type WRe (wt. %: W — 80–95, Re — 5–20) in a solution of (NH4)2CO3 1,0 M was studied using the method of linear voltammetry in potentiodynamic mode and potentiostatic electrolysis. Separation of tungsten and rhenium from the resulting electrolyte was carried out by crystallization of ammonium paratungstate and concentration of rhenium in the mother liquor. A basic technological scheme for the processing of rhenium-containing tungsten alloys is proposed.

Published: December 2023

Inspired by the eumelanin aggregates in human skin, polydopamine nanoparticles (PDA NPs) are promising nanovectors for biomedical applications, especially because of their biocompatibility. We synthesized and characterized fluorescent PDA NPs of 10–25 nm diameter based on a protein containing a lysine–glutamate diad (bovine serum albumin, BSA) and determined whether they can penetrate and accumulate in bacterial cells to serve as a marker or drug nanocarrier. Three fluorescent PDA NPs were designed to allow for tracking in three different wavelength ranges by oxidizing BSA/PDA NPs (Ox-BSA/PDA NPs) or labelling with fluorescein 5-isothiocyanate (FITC-BSA/PDA NPs) or rhodamine B isothiocyanate (RhBITC-BSA/PDA NPs). FITC-BSA/PDA NPs and RhBITC-BSA/PDA NPs penetrated and accumulated in both cell wall and inner compartments of Escherichia coli (E. coli) cells. The fluorescence signals were diffuse or displayed aggregate-like patterns with both labelled NPs and free dyes. RhBITC-BSA/PDA NPs led to the most intense fluorescence in cells. Penetration and accumulation of NPs was not accompanied by a bactericidal or inhibitory effect of growth as demonstrated with the Gram-negative E. coli species and confirmed with a Gram-positive bacterial species (Staphylococcus aureus). Altogether, these results allow us to envisage the use of labelled BSA/PDA NPs to track bacteria and carry drugs in the core of bacterial cells.

The Challenge of Noonomy to Liberal Global Capitalism
Authors:   Emmanuel College, University of Cambridge, Lane D.
Published: December 2023

the latest phase of post-socialist global integration has led to conflicts between the hegemonic core and rising states which are moving from a competitive interdependent semi-core to a challenging economic formation. The rise of a hybrid world system gives opportunities to the semi-core states to enhance their own economic, political and civilisational institutions. Global ideational norms, principally neoliberalism, are confronted by national civilisational ideologies. Noonomy proposes a shift to reindustrialization, greater social solidarity and statist, as well as market forms, of coordination. The paper calls for further developments of noonomy, particularly an ideational vision of the future.

An interview with Amos Gitai on
House
Authors: Brueton Joanne
Published: December 2023

When the Lebanese playwright Wajdi Mouawad invited Israeli filmmaker Amos Gitai to stage his documentary trilogy
House
(1980, 1998, 2005) at the Théâtre national de la Colline in 2023, geopolitical animosities made way for artistic solidarities. In this article and interview, I explore how Gitai’s play critiques the violent logics of home and homelands, exploring how a commandeered house in West Jerusalem plays host to the multidirectional memory of violent Jewish and Palestinian erasure. Stones become metonyms of the Israel–Palestine conflict: as they are quarried, chiselled, split, cemented, and erected, they testify to the construction of homes that also become tools of destruction, expulsion, and mutual ontological violence (Kotef, 2020). Drawing on an interview I conducted with Gitai in July 2023, and his Collège de France lectures from 2018 to 2019, I read his archaeological journey into the remains of this Arab-Jewish house as a call to hospitality (Derrida, 1997): troubling the subject positions of host and hostage that both underpin and impede a ‘chez soi’.
Faire rêver le monde avec Leïla Slimani (entretien)
Authors: Stroia Adina
Published: December 2023

L’écrivaine franco-marocaine Leïla Slimani a fait irruption sur la scène littéraire française avec son premier roman,
Dans le jardin de l’ogre
(2014), qui raconte l’histoire d’Adèle Robinson, une Parisienne de la classe moyenne supérieure qui a un goût prononcé pour les situations sexuelles à risque, penchant qui menace de faire voler en éclats sa vie trop stable. Son deuxième roman,
Chanson douce
(2016), a définitivement consacré Slimani en tant qu’écrivaine en France et à l’étranger. Couronné par le prestigieux Prix Goncourt et acclamé par la critique littéraire, ce deuxième roman est également devenu un bestseller mondial. Inspiré de faits réels,
Chanson douce
met en scène une nounou qui tue les deux enfants de la famille pour laquelle elle travaille. Le roman surprend le lecteur par son rythme aux allures de thriller et par la précision glaçante de son écriture. Alors que l’histoire de ses deux premiers romans se déroulait dans une France contemporaine, les romans les plus récents de Slimani qui font partie d’une trilogie annoncée,
Le Pays des autres
(2020) et
Regardez-nous danser
(2022), plongent le lecteur dans l’histoire récente du Maroc depuis les années 1960 et dresse un portrait détaillé d’un pays en mutation sous la forme d’une saga familiale d’inspiration autobiographique. Le présent entretien prend comme point de départ les écrits les plus récents de l’écrivaine et rassemble les points de vue Slimani sur la nature entremêlée de l’histoire et de l’histoire personnelle ou du récit, la fonction de l’écrivain et de l’écriture à l’ère contemporaine, ainsi que sur les outils nécessaires pour raconter une « histoire vraie ». Nous nous attelons également au passé colonial du Maroc et à la notion d’altérité, ainsi qu’aux approches décoloniales. Nous interrogeons ensuite le projet féministe à travers un prisme postcolonial et nous abordons la question des héritages féministes tout en nous tournant vers la Française du futur et ce à quoi elle pourrait ressembler dans un pays en pleine mutation politique. Cet entretien a eu lieu dans le cadre de la série « Giving Shape to the World: Contemporary Writing in French Today » à l’Institut Français à Londres pendant le Mois de la Francophonie en mars 2022.

VARIETY OF SHOPPING MODES: THEORETICAL FRAMEWORK, PIVOTAL FACTORS, AND MANAGERIAL IMPLICATIONS
Authors: Redondo Ignacio , Charron Jean-Philippe
Published: December 2023

With the development of e-commerce and smartphones, consumers can use a variety of shopping modes (i.e., showrooming, webrooming, and completely offline/online shopping), each of which provides specific advantages in terms of price, assortment, service, etc. Using a great variety of these shopping modes can confer many benefits. However, previous studies have found evidence of sizable segments of consumers who typically avoid using a great variety of shopping modes. To understand the contrast in consumers’ variety of shopping modes, we propose a theoretical framework and measure the effect of the desired variety in the information-seeking and purchase processes. Results – from a representative sample of the Spanish consumers – confirm that the variety of shopping modes pivots on the extent to which e-commerce use, smartphone use, offline and online interactivity, and online device interchangeability differ. Better understanding the variety of shopping modes may help marketers adjust their channel strategies to the actual preferences of different consumer segments and assess the economic viability of an omnichannel approach.
Low-frequency Internal Gravity Waves Are Pseudo-incompressible
Authors: Hindman Bradley W. , Julien Keith
Published: December 2023

Starting from the fully compressible fluid equations in a plane-parallel atmosphere, we demonstrate that linear internal gravity waves are naturally pseudo-incompressible in the limit that the wave frequency ω is much less than that of surface gravity waves, i.e.,

ω
≪

gk

h

, where g is the gravitational acceleration and k

h
is the horizontal wavenumber. We accomplish this by performing a formal expansion of the wave functions and the local dispersion relation in terms of a dimensionless frequency

ε
=
ω

/

gk

h

. Further, we show that, in this same low-frequency limit, several forms of the anelastic approximation, including the Lantz–Braginsky–Roberts formulation, poorly reproduce the correct behavior of internal gravity waves. The pseudo-incompressible approximation is achieved by assuming that Eulerian fluctuations of the pressure are small in the continuity equation—whereas, in the anelastic approximation, Eulerian density fluctuations are ignored. In an adiabatic stratification, such as occurs in a convection zone, the two approximations become identical. However, in a stable stratification, the differences between the two approximations are stark and only the pseudo-incompressible approximation remains valid.
Digging into the Interior of Hot Cores with ALMA: Spiral Accretion into the High-mass Protostellar Core G336.01–0.82

We observed the high-mass star-forming core G336.01–0.82 at 1.3 mm and 0.″05 (∼150 au) angular resolution with the Atacama Large Millimeter/submillimeter Array (ALMA) as part of the Digging into the Interior of Hot Cores with ALMA survey. These high-resolution observations reveal two spiral streamers feeding a circumstellar disk at opposite sides in great detail. Molecular line emission from CH3OH shows velocity gradients along the streamers consistent with infall. Similarly, a flattened envelope model with rotation and infall implies a mass larger than 10 M
☉ for the central source and a centrifugal barrier of 300 au. The location of the centrifugal barrier is consistent with local peaks in the continuum emission. We argue that gas brought by the spiral streamers is accumulating at the centrifugal barrier, which can result in future accretion burst events. A total high infall rate of ∼4 × 10−4
M
☉ yr−1 is derived by matching models to the observed velocity gradient along the streamers. Their contribution accounts for 20%–50% the global infall rate of the core, indicating streamers play an important role in the formation of high-mass stars.

The direct imaging of an Earth-like exoplanet will require sub-nanometric wave-front control across large light-collecting apertures to reject host starlight and detect the faint planetary signal. Current adaptive optics systems, which use wave-front sensors that reimage the telescope pupil, face two challenges that prevent this level of control: non-common-path aberrations, caused by differences between the sensing and science arms of the instrument; and petaling modes: discontinuous phase aberrations caused by pupil fragmentation, especially relevant for the upcoming 30 m class telescopes. Such aberrations drastically impact the capabilities of high-contrast instruments. To address these issues, we can add a second-stage wave-front sensor to the science focal plane. One promising architecture uses the photonic lantern (PL): a waveguide that efficiently couples aberrated light into single-mode fibers (SMFs). In turn, SMF-confined light can be stably injected into high-resolution spectrographs, enabling direct exoplanet characterization and precision radial velocity measurements; simultaneously, the PL can be used for focal-plane wave-front sensing. We present a real-time experimental demonstration of the PL wave-front sensor on the Subaru/SCExAO testbed. Our system is stable out to around ±400 nm of low-order Zernike wave-front error and can correct petaling modes. When injecting ∼30 nm rms of low-order time-varying error, we achieve ∼10× rejection at 1 s timescales; further refinements to the control law and lantern fabrication process should make sub-nanometric wave-front control possible. In the future, novel sensors like the PL wave-front sensor may prove to be critical in resolving the wave-front control challenges posed by exoplanet direct imaging.
Why forest economy can become a driving force of the development of BRICS cooperaion
Authors: Pyzhev Anton
Published: December 2023

The changing global geopolitical and economic landscape generates growing interest in new strategic alliances among the world’s fastest growing economies. This is certainly true for the BRICS countries, whose importance for the contemporary world cannot be overestimated. As soon as the group begins to turn into a more institutionalized organization, the question of establishing closer and more numerous economic and social ties will arise. The paper analyzes the trends in the development of the forest economy in Brazil, Russia, India, China and South Africa over the past two decades. It assesses each country’s share in the global timber harvesting and its position on the international market for forest products. Accounting for slightly less than 1/3 of the global annual harvest, the BRICS countries have boosted production and export of their forest products in the XXI century. According to our calculations, only India and China’s production and export of sawn timber and wood panels increased tenfold. The paper examines conditions for turning the forest economy into one of the drivers of cooperation between the BRICS countries and the existing financial, political and environmental constraints. Such cooperation will be possible if there is sufficient demand for forestry products in BRICS; it will require measures to radically improve the logistics of trade between the countries, given their great mutual remoteness. The important role of the BRICS countries in the global forest economy can become an important factor in the further development of cooperation within the group, especially after the expansion expected in 2024.

Authors: Ballarini Marie , Delestage Charles-Alexandre
Published: December 2023

À la faveur du développement des technologies immersives, la réalité virtuelle entre, par touches progressives, dans des dispositifs de médiation muséale ou patrimoniale. Ces objets, s’ils ne s’affranchissent pas des leçons tirées des autres incursions du numérique dans les musées, apportent leur lot de questionnements du fait de la notion de présence qu’il convoque, et qui rencontre une dynamique liée à la question des émotions des visiteurs dans les expositions abordées depuis une vingtaine d’années. Par l’étude de trois dispositifs déployés dans des institutions muséales et patrimoniales majeures (Louvre, Louvre-Lens, Grotte Chauvet), nous proposons une réflexion sur la négociation entre les différents acteurs liés à ces dispositifs, où les impératifs émotionnels et de médiations se confrontent.
Ganar voluntades para unir imperios: el viaje a Europa de Buenaventura Ibáñez a finales del siglo XVII
Authors: Torres Trimállez Marina
Published: December 2023

Este trabajo tiene por objetivo estudiar el viaje que realizó el franciscano español Buenaventura Ibáñez (1607-‍1691) desde China a Europa para negociar concesiones para las misiones en China y reclutar nuevos misioneros. Habiendo salido en 1661 de Jinan, al norte de China, el fraile pasó por Macao, Malasia, la India, el Golfo Pérsico y Oriente Próximo. Durante su viaje en Europa, el misionero visitó Roma y Madrid donde desarrolló una intensa labor negociadora que finalizó con su regreso con nuevos refuerzos a la misión China en 1669. A través de una selección de cartas, memoriales, súplicas y relaciones de este misionero, así como de la documentación conservada de aquellos que trataron con él, este trabajo pretende reconstruir su rol como procurador de la misión China. El estudio de sus acciones sirve para entender la puesta en marcha del proyecto misional franciscano en los siglos XVII y XVIII, así como para analizar las redes de poder en Asia Oriental entre las que se movió este fraile.

Published: December 2023

This study presents a markerless video-based human gait analysis system for automatic assessment of at-home rehabilitation. A marker-based MoCap system (Vicon) is used to evaluate the accuracy of the proposed approach. Additionally, a novel gait rehabilitation score based on the Dynamic Time Warping (DTW) algorithm is introduced, enabling quantification of rehabilitation progress. The accuracy of the proposed approach is assessed by comparing it to a marker-based MoCap system (Vicon), which is used to evaluate the proposed approach. This evaluation results in mean absolute errors (MAE) of 4.8° and 5.2° for the left knee, and 5.9° and 5.7° for the right knee, demonstrating an acceptable accuracy in knee angle measurements. The obtained scores effectively distinguish between normal and abnormal gait patterns. Subjects with normal gait exhibit scores around 97.5%, 98.8%, while those with abnormal gait display scores around 30%, 29%, respectively. Furthermore, a subject at an advanced stage of rehabilitation achieved a score of 65%. These scores provide valuable insights for patients, allowing them to assess their rehabilitation progress and distinguish between different levels of gait recovery. The proposed markerless approach demonstrates acceptable accuracy in measuring knee joint angles during a sagittal walk and provides a reliable rehabilitation score, making it a convenient and cost-effective alternative for automatic at-home rehabilitation monitoring.
Automated Detection of Dental Caries from Oral Images using Deep Convolutional Neural Networks

Published: December 2023

The urgent demand for accurate and efficient diagnostic methods to combat oral diseases, particularly dental caries, has led to the exploration of advanced techniques. Dental caries, caused by bacterial activities that weaken tooth enamel, can result in severe cavities and infections if not promptly treated. Despite existing imaging techniques, consistent and early diagnoses remain challenging. Traditional approaches, such as visual and tactile examinations, are prone to variations in expertise, necessitating more objective diagnostic tools. This study leverages deep learning to propose an explainable methodology for automated dental caries detection in images. Utilizing pre-trained convolutional neural networks (CNNs) including VGG-16, VGG-19, DenseNet-121, and Inception V3, we investigate different models and preprocessing techniques, such as histogram equalization and Sobel edge detection, to enhance the detection process. Our comprehensive experiments on a dataset of 884 oral images demonstrate the efficacy of the proposed approach in achieving accurate caries detection. Notably, the VGG-16 model achieves the best accuracy of 98.3% using the stochastic gradient descent (SGD) optimizer with Nesterov’s momentum. This research contributes to the field by introducing an interpretable deep learning-based solution for automated dental caries detection, enhancing diagnostic accuracy, and offering potential insights for dental health assessment.

Authors: Kandiero Agripah , Chizwina Sabelo
Published: December 2023

The teaching of large classes has emerged as a teaching and learning challenge. Due to the national government of South Africa policy, universities have had to increase enrolments of first-year students. This chapter uses the context of a private institution of higher learning in South Africa as the site of the project to show how a community of practice (CoP) can be utilised to assist in developing strategies for increasing student engagement. It is the argument of this chapter that a CoP will assist lecturers in solving their teaching challenges. Different tools were examined that could be used in CoP based on their affordances. The blog was identified as the best tool to create a CoP. Introducing a CoP will ensure more collaboration and interaction among the lecturers.
General and Discipline-Specific Challenges to Implementing Outcome-Based Education in India
Authors: Singh Sanyogita , Singh Vikram
Published: December 2023

Outcome-based education—a learner-centric teaching-learning approach—involves a paradigm shift in terms of reorientation of curriculum, delivery of learning material, and assessment in light of learning outcomes. In 2014, India became a signatory to the Washington Accord on OBE through the National Board of Accreditation, which looks after the accreditation of engineering and management programs. Later, UGC and NCTE also issued OBE manuals for general and teacher education institutes, respectively. It is believed that India faces diverse and complex challenges in implementing OBE. These include a lack of understanding and awareness of the OBE among the stakeholders, inadequate infrastructure, insufficient faculty training, and difficulties in developing appropriate assessment tools and methods. This chapter has examined the general and discipline-specific challenges in implementing OBE in the Indian context. A set of recommendations and potential solutions to deal with the challenges to OBE implementation in India has also been listed.
A Machine Learning-Based Admissions Support System With a Case Study on D.K.M. College for Women, Vellore
Authors: Vasumathy M.
Published: December 2023

Building efficient higher education systems is tough for India and other developing countries, especially when it comes to female students. Despite the government's efforts, India did not gain anything from its superb and creative educational policy. The Indian government is cognizant of the particular challenges the current global situation poses for the higher education industry. At Vellore's D.K.M. College for Women, the post-graduation admission rate has considerably declined over the last 12 months. The work is largely focused on the identification of concerns, obstacles, and declining factors of post-graduation admittance from the perspectives of students, parents, teaching staffs, and management. The architecture for the course recommender system and the information flow across it are proposed in this chapter. This approach forecasts the ideal subject pairing, or the subjects that pupils will be most interested in. Here, the authors use a learning management system like Moodle to gather information from students about their course preferences.
Drives and Motives During Online Degree Completion
Authors: Cherrstrom Catherine A.
Published: December 2023

This study examined the motives and drives of adult students during online degree completion, including the commonalities among and differences between Hispanic and non-Hispanic adult students. Participants included 364 adult students at a Hispanic-serving institution (HSI) who completed a series of reflective writing assignments, generating over 15,000 pages of data. After linguistic and statistical data analysis, results identified the drives and motives common to all adult students and significant differences between Hispanic and non-Hispanic adult students. Some merit little or no action, while three offer opportunities—achievement and affiliation as drives, the states of acquire and lack, and allure as motive. These results offer implications for Hispanic and non-Hispanic adult students and those in higher education who serve or teach such students—academic advisors, instructional designers, instructors, and program administrators—and inform how technology can support such efforts.
