The high-temperature behaviour of a feldspar-group mineral, filatovite (with the simplified formula: K(Al,Zn)2(As,Si)2O8), in which the Al:As:Si ratio is close to 2:1:1), was studied by in situ high-temperature single-crystal X-ray diffraction and in situ high-temperature (hot stage) Raman spectroscopy up to 600°C. In the temperature range studied (25–600°С) filatovite does not undergo any phase transition, whereas at 800°C it decomposes to X-ray amorphous phase(s). The evolution of 12 main Raman bands was traced during heating, which indicates a gradual change in the crystal structure. The thermal expansion coefficients of filatovite demonstrate a sharply anisotropic character of thermal expansion: the maximal expansion is close to the a axis (α11 = 17.7(1) × 10–6 °C–1), whereas along the b and c axes the thermal expansion coefficients are close to zero. Such behaviour is typical for minerals with a similar crystal structure topology; it indicates the dominant role of structure geometry in the thermal behaviour of the mineral.

This Special Issue brings together scholars working in a variety of contexts to explore the concepts of solidarity and socialist internationalism as a mass phenomenon. While recent scholarship has begun to document linkages between the socialist and (post)colonial world during the Cold War, most of this work has eschewed a focus on the mass, social experience of internationalism, instead emphasizing the transformative role played by small groups of mobile elites. But if the direct experience of socialist internationalism was limited to a privileged few, how then was it experienced by the majority, for whom actual travel outside of their state was a distant possibility? This issue explores how socialist internationalism and its attendant practices of solidarity functioned within and between socialist societies. Where it does take border-transcending groups as its subject, it explores the socio-historical, everyday implications of this transnational story. For much of the Cold War, state and party-led practices of internationalism were a central component of everyday life, but little is known about these practices as they manifested on the ground. To shed light on this, this Special Issue explores how depictions of solidarity manifested in mass culture; how everyday practices emerged out of socialist internationalism and anti-imperialism; and how institutions that sought to bridge gaps between societies through solidarity emerged and then transformed or disappeared after 1989.

Since the first developments of anthropogenic lime materials radiocarbon (14C) dating in the 1960s, numerous studies have been undertaken and developed to investigate the topic further. Historic mortars are complex composite and open system materials that can incorporate a large range of components. Due to the complexity of the historic lime mortars composition, they are not part of a routine protocol in most radiocarbon laboratories and reliable dating is not always achieved. A thorough characterization needs to be performed and different preparation methods can be considered as a function of their compositions. A vast range of terms are employed to qualify the lime mortars components and alterations that can possibly have an influence on the dating result. Here, a detailed description of these components and the various terms used is listed. To illustrate this, images obtained by thin-section petrography and cathodoluminescence are presented in addition to radiocarbon results using stepwise acid hydrolysis on Belgian mortars having different provenance, state, age and composition. Depending on the type of aggregate used, the type of binder and its conservation state, the eventual presence of weathering carbonates and the assumed speed of the carbonation process, the reliability of radiocarbon measurements using the stepwise acid hydrolysis technique is discussed and confronted with presumed historical constraints.

The study evaluated forage and livestock performance in different grazing systems over two years. Treatments were three contrasting grazing systems: (I) N-fertilized bahiagrass (Paspalum notatum Flüggé) in the summer overseeded during the winter by N-fertilized ryegrass (Lolium multiflorum) and oat (Avena sativa L.) (Grass + N); (II) unfertilized bahiagrass during the summer overseeded with ryegrass + oat and a blend of clovers (Trifolium spp.) in the winter (Grass + Clover); (III) unfertilized bahiagrass and rhizoma peanut (RP; Arachis glabrata Benth.) mixture during summer, overseeded during winter by ryegrass + oat + clovers mixture (Grass + Clover + RP). Average daily gain (ADG), gain per area (GPA), and stocking rate (SR) in the winter did not differ across treatments and averaged 0.87 kg/d (P = 0.940), 303 kg/ha, and 2.72 AU/ha. In the summer, Grass + Clover + RP had greater ADG than Grass + N (0.34 vs. 0.17 kg/d, respectively). During the summer, the GPA of Grass + Clover + RP was superior to Grass + N (257 vs. 129 kg/ha, respectively), with no difference in SR among treatments at 3.19 AU/ha. Over the entire year, ADG and GPA tended to be greater for Grass + Clover + RP. Annual SR differed between treatments, where Grass + N was greater (3.37 AU/ha) than the other treatments, which averaged 2.76 AU/ha. Integration of legumes into pasture systems in the summer and winter contributes to developing a sustainable grazing system, reducing N fertilizer use by 85% while tending to increase livestock productivity even though SR was decreased by 18%.

The article aims to sketch out the main features of the political culture of the Radical Party (PR). This political culture is paradigmatic of a much broader phenomenon that has affected the politics of Western democracies since the 1970s: the critique of traditional parties in the name of a party model formed by spontaneous groupings of society; the extreme emphasis placed on individual choices in political action, and the programmatic tracing of the latter back to the former; and the call for a less ‘mediated’ relationship between citizens and institutions. Yet, this culture contained certain ingredients that would distance it from the populist forms of the twenty-first century. After grafting anti-authoritarianism onto its liberal matrix the PR identified the promotion of civil rights as the goal and battle for the transformation of the relationship between politics and the citizen. This transformation emphasised the sphere of individual freedom and the liberty to participate in community decisions, and thus implied a transformation of the ways and means of doing politics. In the late 1970s, the PR deepened its critique of parties and partitocracy and, at the same time, emphasised a supranational view of politics, eventually becoming a ‘transnational transparty’ party in 1989.

In March 1674, Hungary's Lutheran and Calvinist clergy stood collectively accused of fomenting rebellion against the Habsburgs and seeking protection from the Ottomans. A widely publicized tribunal in Pozsony (Bratislava, Pressburg) resulted in systematic expulsions, incarcerations, and the sale of forty-two pastors as galley slaves. A voluminous body of historiography has been dedicated to the victims of the tribunal and their tribulations. It is commonly assumed that the accusations against the Protestant clergy were fabricated. This article shifts the focus from martyrologies, sermons, and narratives written after the year 1674 to eyewitness accounts in inquisitorial records, letters, petitions, official reports, and military dispatches from the years leading up to the Pozsony Tribunal. These unstudied testimonies in the Hungarian and Austrian archives reveal that a significant number of pastors participated in popular resistance and revolt against a brutal Habsburg Counter Reformation. Many put their hopes in the Ottomans whom they considered protectors against the destruction of their religion. These little-known developments shed light on important larger historical realities that have been eclipsed by Habsburg and Central European historians, namely, Hungarian popular hopes for liberation from the Habsburgs by the Ottomans which culminated in two major revolts in 1670 and 1672.

Wearable sleep trackers are increasingly used in applied psychology. Particularly, the recent boom in the fitness tracking industry has resulted in a number of relatively inexpensive consumer-oriented devices that further enlarge the potential applications of ambulatory sleep monitoring. While being largely positioned as wellness tools, wearable sleep trackers could be considered useful health devices supported by a growing number of independent peer-reviewed studies evaluating their accuracy. The inclusion of sensors that monitor cardiorespiratory physiology, diurnal activity data, and other environmental signals allows for a comprehensive and multidimensional approach to sleep health and its impact on psychological well-being. Moreover, the increasingly common combination of wearable trackers and experience sampling methods has the potential to uncover within-individual processes linking sleep to daily experiences, behaviors, and other psychosocial factors. Here, we provide a concise overview of the state-of-the-art, challenges, and opportunities of using wearable sleep-tracking technology in applied psychology. Specifically, we review key device profiles, capabilities, and limitations. By providing representative examples, we highlight how scholars and practitioners can fully exploit the potential of wearable sleep trackers while being aware of the most critical pitfalls characterizing these devices. Overall, consumer wearable sleep trackers are increasingly recognized as a valuable method to investigate, assess, and improve sleep health. Incorporating such devices in research and professional practice might significantly improve the quantity and quality of the collected information while opening the possibility of involving large samples over representative time periods. However, a rigorous and informed approach to their use is necessary.

Kristjánite, KNa2H(SO4)2, is a new mineral (IMA2022–131) found in a high-temperature fumarole on Fimmvörðuháls, Iceland. It is monoclinic, P21/n, a = 6.9625(1), b = 9.9953(1), c = 11.0928(2) (Å), β = 105.637(2)° and V = 743.40(2) Å3. Kristjánite forms colourless transparent crystals up to ~100 μm in size in compact aggregates with metathénardite, belomarinaite, aphthitalite, ivsite and an unknown mineral with tentative composition K2NaH(SO4)2, or grows in white globules of smaller grains on their surface. The eight strongest maxima in a powder X-ray diffraction diagram are [d, Å (Intensity)] 4.37 (59), 3.65 (32), 3.48 (78), 3.36 (100), 3.18 (76), 2.83 (43), 2.73 (38) and 2.405 (23). The mineral represents a novel crystal structure type. In it, K is coordinated by eight O atoms, and two symmetrically independent Na atoms by seven O atoms. Two symmetrically independent S atoms are in tetrahedral coordination by O atoms. A close to linear, very short hydrogen bond (2.44 Å), connects the two to a SO4–H–SO4 dimer. K and Na coordination polyhedra share vertices, edges and even faces forming with sulfate tetrahedra a tight structure with narrow [100] channels lined on two opposite sides by hydrogen bonds.

We report an uncommon case report of total anomalous pulmonary venous returns into the right atrium at the base of the superior caval vein’s ostium without a sinus venosus defect, in situs solitus, without vertical vein or a posterior pulmonary venous confluence.

This article investigates the solidarity campaigns supporting refugees from the Greek Civil War (1946–1949) in post-war Czechoslovakia and the emerging German Democratic Republic. Framed as an important bridge between the interwar and later Cold War forms of socialist internationalism, this case sheds light on its transitory character, revealing the narrative shift from anti-fascist to anti-imperialist contexts and the increasingly institutionalized and ritualized solidarity. Thus, not only was practising solidarity already an integral part of post-war socialist regimes, but it also served a variety of functions, contributing to the legitimization and identity of the Eastern bloc. Based on archival documents and press, the article uncovers the deployment of analogical institutional structures employed by both states, thus opening up the sphere of interaction with their citizens, mobilized to become involved in various ways. The two countries, however, departed from different positions, dealing with opposing legacies of the wartime experience, which influenced the motivations employed in their campaigns. Entangled in discourses of guilt, heroism, and victimhood, yet aligned under the proclaimed values of socialist brotherhood and anti-fascism, building internationalist solidarity in both countries worked alongside and even boosted attempts to overcome the obstacle of the Nazi past, both internally and in their mutual relationship. This article thus contributes to a better understanding of how internationalist solidarity functioned as a platform to build bridges – not only towards the “South”, but also within the Eastern bloc.

In this paper, we consider random iterations of polynomial maps $z^{2} + c_{n}$, where $c_{n}$ are complex-valued independent random variables following the uniform distribution on the closed disk with center c and radius r. The aim of this paper is twofold. First, we study the (dis)connectedness of random Julia sets. Here, we reveal the relationships between the bifurcation radius and connectedness of random Julia sets. Second, we investigate the bifurcation of our random iterations and give quantitative estimates of bifurcation parameters. In particular, we prove that for the central parameter $c = -1$, almost every random Julia set is totally disconnected with much smaller radial parameters r than expected. We also introduce several open questions worth discussing.

We investigate large set axioms defined in terms of elementary embeddings over constructive set theories, focusing on $\mathsf {IKP}$ and $\mathsf {CZF}$. Most previously studied large set axioms, notably, the constructive analogues of large cardinals below $0^\sharp $, have proof-theoretic strength weaker than full Second-Order Arithmetic. On the other hand, the situation is dramatically different for those defined via elementary embeddings. We show that by adding to $\mathsf {IKP}$ the basic properties of an elementary embedding $j\colon V\to M$ for $\Delta _0$-formulas, which we will denote by $\Delta _0\text {-}\mathsf {BTEE}_M$, we obtain the consistency of $\mathsf {ZFC}$ and more. We will also see that the consistency strength of a Reinhardt set exceeds that of $\mathsf {ZF+WA}$. Furthermore, we will define super Reinhardt sets and $\mathsf {TR}$, which is a constructive analogue of V being totally Reinhardt, and prove that their proof-theoretic strength exceeds that of $\mathsf {ZF}$ with choiceless large cardinals.
