A clay from Weslatiya that is widely used in Tunisian ceramic production has abundant reserves but generates significant waste, posing environmental concerns if not handled appropriately. This study explores the valorization of this local clay by incorporating ceramic waste (chamotte) and quartz sand to produce eco-friendly materials, in line with sustainability and circular economy principles. X-ray diffraction and scanning electron microscopy analyses reveal that incorporating chamotte at levels exceeding 15% by weight improves the material’s properties. The Young’s modulus of the composite increases to 80 GPa, more than 2.5 times that of the basic clay. Chamotte can replace up to 30% of quartz sand without significantly affecting densification or porosity while preserving structural integrity. This approach offers flexibility in terms of material composition, enhancing performance and promoting sustainability by reusing waste materials for high-performance ceramics in industrial applications.

The transport industry of Ukraine is an integral part of its economy. According to the National Transport Strategy of Ukraine, a critical strategic goal is to enhance transport safety. Currently, there is a gap in mobile devices capable of automatically measuring slopes and evenness of both runways and road surfaces in two coordinates. This paper addresses the creation of new methods for assessing longitudinal and transverse slopes using micromechanical systems. The study highlights international experiences, presents practical applications and proposes strategies for overcoming implementation challenges. A detailed roadmap for deployment and further improvements is provided.

Recognizing the distributed nature of agency in human–AI interactions, this article proposes a framework for examining the power dynamics that undergird the use of generative AI (GenAI) for language learning. Drawing on Darvin and Norton’s model of investment, it adopts a critical sociomaterial lens to cast a light on the entanglement of bodies, objects and discourse in these interactions, while highlighting how issues of positioning, access to resources, and ideological reproduction emerge from this perspective. Human agency both interacts with and is constrained or amplified by the functionalities of GenAI. To invest in agentive GenAI practices that enable meaningful learning and the achievement of their own intentions, learners must not only recognize the power of GenAI to steer interactions and promote specific ways of thinking, but also resist fully delegating the production of meaning and texts to technology. Cultivating critical digital literacies that recognize how power operates in human-AI interactions is integral to fostering reflexive, inclusive and equitable language learning and teaching in the age of GenAI.

During the first half of the nineteenth century, Mid-Atlantic States expanded guardianship to include habitual drunkards. Legislators in Pennsylvania, New York, and New Jersey empowered courts to put habitual drunkards under guardianship, a legal status that stripped them of their rights to own property, enter into contracts, make wills, and, in some states, even vote. Amid the dramatic nineteenth-century expansion of male suffrage, the habitual drunkard signified a masculine failure of self-government that disqualified propertied men from the privileges of full citizenship. The struggle to define habitual drunkenness, detect the habitual drunkard, and put him under guardianship transformed the courtroom into an arena for contesting the thresholds of compulsion, policing respectable manhood, and drawing the borders of full citizenship in the nineteenth-century United States.

This longitudinal survey examined the effect of the National Healthcare Safety Network’s (NHSN) recently updated Clostridioides difficile test method definition on reporting of hospital-onset C. difficile. Among six hospitals with ≥ 5 years of data available, the updated NHSN definition was associated with improved concordance between predicted versus reported cases.

We apply a synthesis review to revisit the concept, measurement, and operationalisation of social inclusion and exclusion in the context of comparative social policy, integrating the vast literature on the concepts, with the aim of elucidating a clearer understanding of the concepts for use by scholars and policymakers around the planet. In turn, we outline the conceptual development of the concepts, how they have been operationalised through social policy, and how they have been measured at the national and individual levels. Through our review, we identify limitations in extant conceptualisation and measurement approaches and suggest directions for refining conceptual and measurement frameworks to enhance their utility in social inclusion policy, emphasising the concepts’ multidimensional, multilevel, dynamic, and relational essence and highlighting their connection to related concepts such as social capital, social integration, and social citizenship.

We give a notion of boundary pair $(\mathcal{B}_-,\mathcal{B}_+)$ for measured groupoids which generalizes the one introduced by Bader and Furman [BF14] for locally compact groups. In the case of a semidirect groupoid $\mathcal{G}=\Gamma \ltimes X$ obtained by a probability measure preserving action $\Gamma \curvearrowright X$ of a locally compact group, we show that a boundary pair is exactly $(B_- \times X, B_+ \times X)$, where $(B_-,B_+)$ is a boundary pair for $\Gamma$. For any measured groupoid $(\mathcal{G},\nu )$, we prove that the Poisson boundaries associated to the Markov operators generated by a probability measure equivalent to $\nu$ provide other examples of our definition. Following Bader and Furman [BF], we define algebraic representability for an ergodic groupoid $(\mathcal{G},\nu )$. In this way, given any measurable representation $\rho \,:\,\mathcal{G} \rightarrow H$ into the $\kappa$-points of an algebraic $\kappa$-group $\mathbf{H}$, we obtain $\rho$-equivariant maps $\mathcal{B}_\pm \rightarrow H/L_\pm$, where $L_\pm =\mathbf{L}_\pm (\kappa )$ for some $\kappa$-subgroups $\mathbf{L}_\pm \lt \mathbf{H}$. In the particular case when $\kappa =\mathbb{R}$ and $\rho$ is Zariski dense, we show that $L_\pm$ must be minimal parabolic subgroups.

Neurodegenerative diseases (NDDs) are a group of complex disorders marked by pathophysiological mechanisms involving protein aggregation, mitochondrial dysfunction, oxidative stress and neuroinflammation. Irrespective of extensive research advances, NDDs have become a serious global concern and persist as a major therapeutic challenge. In recent years, microRNAs (miRNAs), a class of small non-coding RNAs, have established a pivotal role in combating NDDs. The altered expression of miRNAs is reported to be associated with the progression of various NDDs. This review aims to discuss miRNA biogenesis; dysregulation in NDDs, specifically Alzheimer’s disease, Parkinson’s disease (PD) and amyotrophic lateral sclerosis; their potential as biomarkers; and promising therapeutic targets. Additionally, there are various emerging technologies discussed that are advanced approaches to enhance miRNA-based diagnostics and therapeutics.

Highlights from the International Symposium on Twins, held at the University of Crete on May 23−24, 2025, are summarized. The symposium, organized by Dr Maria Markodimitraki, Professor in the Department of Preschool Education at the University of Crete, attracted scholars and practitioners from Greece and around the world. Meetings with a pair of reunited monozygotic female twins, and a female twin in search of her sister, also from Greece, are described. This review is followed by summaries of twin research on neonatal outcomes, growth discordance and restriction, and romantic partners and alcohol use. Human interest stories include a book documenting the extraordinary lives of identical twins Celia and Mamaine Paget, a museum wing honoring the lost Rockefeller twin, a remarkable conjoined twinning case in India, the death of an Australian sports icon, and a most unusual triplet birth.

In March 1933, the United States Congress declared beer up to 3.2 percent alcohol by weight to be “non-intoxicating,” thus allowing it to be produced and sold while the nation was still under the 18th Amendment’s ban of intoxicating liquors. Brewers had long argued that beer was a temperance beverage that should be regulated with a lighter touch than harder liquor. In fact, the declaration that 3.2 beer was non-intoxicating opened several markets that would otherwise have been closed to brewers. In the decades that followed Repeal, 3.2 beer continued to be treated differently than stronger alcohol with respect to who, when, where, and how it was legally available. This paper explores the important—and continuing—role that 3.2 beer has played in the post-Prohibition United States.
