Dirac rings are commutative algebras in the symmetric monoidal category of $\mathbb {Z}$-graded abelian groups with the Koszul sign in the symmetry isomorphism. In the prequel to this paper, we developed the commutative algebra of Dirac rings and defined the category of Dirac schemes. Here, we embed this category in the larger $\infty $-category of Dirac stacks, which also contains formal Dirac schemes, and develop the coherent cohomology of Dirac stacks. We apply the general theory to stable homotopy theory and use Quillen’s theorem on complex cobordism and Milnor’s theorem on the dual Steenrod algebra to identify the Dirac stacks corresponding to $\operatorname {MU}$ and $\mathbb {F}_p$ in terms of their functors of points. Finally, in an appendix, we develop a rudimentary theory of accessible presheaves.

After more than five years of development, we present a new version of Dark Sage, a semi-analytic model (SAM) of galaxy formation that breaks the mould for models of its kind. Included among the major changes is an overhauled treatment of stellar feedback that is derived from energy conservation, operates on local scales, affects gas gradually over time rather than instantaneously, and predicts a mass loading factor for every galaxy. Building on the model’s resolved angular momentum structure of galaxies, we now consider the heating of stellar discs, delivering predictions for disc structure both radially and vertically. We add a further dimension to stellar discs by tracking the distribution of stellar ages in each annulus. Each annulus–age bin has its own velocity dispersion and metallicity evolved in the model. This allows Dark Sage to make structural predictions for galaxies that previously only hydrodynamic simulations could. We present the model as run on the merger trees of the highest-resolution gravity-only simulation of the MillenniumTNG suite. Despite its additional complexity relative to other SAMs, Dark Sage only has three free parameters, the least of any SAM, which we calibrate exclusively against the cosmic star formation history and the $z = 0$ stellar and H i mass functions using a particle-swarm optimisation method. The Dark Sage codebase, written in C and python, is publicly available at https://github.com/arhstevens/DarkSage.

According to some of the past half-century’s most influential critics of liberalism, John Locke is the pivotal subverter of the pre-modern ethical tradition. Locke’s view of nature and of human nature, the story goes, divorced ethics from natural teleology and so set off an inevitable spiral downward into moral dissolution. This story about Locke remains influential even though the last fifty years of Locke scholarship have brought a cascade of studies treating Locke as operating within the tradition of Reformed natural law. These studies, in part because they embrace a distorted view of Locke’s conception of the person, have failed to address satisfactorily the crux of the story told by the critics of liberalism. This article corrects that distortion and demonstrates how natural teleology operates within Locke’s ethics. I show how Locke sought to identify the teleological ordering of human beings to the supreme good by developing a relational conception of the person, analysing the human being as embedded in and defined by a web of relationships including neighbour and God. The result is a Locke far more in continuity with pre-modern ethical approaches than has hitherto been realized, one who sought to preserve natural teleology for the modern world.

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.
