Reactivity of Alkali Metal Yldiides Toward Carbon Disulfide
The use of carbon disulfide as CS source for the construction of sulfur-containing molecules is an attractive strategy in organic synthesis. Herein, we report the formation of CS2 adducts with α-metalated ylides. The resulting alkali metal salts are readily isolable and were char...

We present an Australian Square Kilometre Array Pathfinder (ASKAP) Evolutionary Map of the Universe (EMU) radio-continuum detection of the nearby spiral Seyfert I type galaxy NGC 7213 which we nickname ‘sand-timer’ due to its morphological appearance. We find an intriguing and pe...

Cosmological Constraints from Full-scale Clustering and Galaxy–Galaxy Lensing with DESI DR1
Abstract We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy–galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1. Our analysis includes four samples drawn from the Bright Galaxy Survey (B...

Argument A history of “common sense” concerns as much the epistemological concept as the very architecture of human rational judgment. The historian of medieval philosophy Étienne Gilson (1884–1978) cast nineteenth-century Jesuit appeals to common sense as a costly defense agains...

Abstract. We propose a novel, rigorous, and conservative invariant-domain preserving (IDP) projection technique between solution spaces of differing discretizations. The projection preserves important physical invariants of the underlying hyperbolic system, for example, positivit...

Exploring Usability and Legal Practice: Insights From German Judicial Users of Digital Forensics
Digital forensics has become an integral part of modern criminal proceedings, yet its effective integration remains challenging because of increasing data volumes, evolving technologies, and complex interactions between technical and legal stakeholders. Although prior work has fo...

Extendability of the $$B_2$$-Arrangement
Abstract Let $$({\mathscr {A}},m)$$ ( A , m ) be a free multiarrangement, and let $${\mathscr {E}}$$ E be an extension of $$({\mathscr {A}},m)$$ ( A , m ) . It is well known that if $${\mathscr {A}}$$ A is the Coxeter arrangement of type $$A_2$$ A 2 , then a free extension of $$(...

Experimental Signature of Transient Symmetry Breaking in a Cavity Dirty-Limit Superconductor
Abstract Transient states of matter far from equilibrium may exhibit physical properties beyond those allowed by the equilibrium-state crystalline symmetries. We explore ultrafast and direct electronic excitations of transient states in a dirty-limit superconductor with time-reso...

The directional nature of heat conduction in semiconductor superlattices—marked by significant differences between in-plane and cross-plane pathways—poses substantial challenges for precise thermal property assessment. Conventional frequency-domain thermoreflectance (FDTR) techni...

Machine learning accelerated exploration of the global high pressure phase diagram
Pressure reshapes electronegativity, chemical hardness, and bonding, stabilizing compounds and crystal symmetries inaccessible at ambient conditions, yet accurate phase diagrams at high pressure exist for only a small fraction of elemental combinations, and their exploration acro...

Global dimensions of local geodesic ghor algebras
A ghor algebra is a path algebra with relations of a dimer quiver on a compact surface. We show that the global dimension of any cyclic localization of a geodesic ghor algebra on a genus g ≥ 1 surface is bounded above by 2 g + 1 . This number coincides with the Krull dimension of...

Massively Multiplexed Photonic Chip With Cross‐Channel Fusion For Harmonized Biosensing
ABSTRACT Accurate, label‐free analysis of complex biological mixtures is limited by poor multiplexing scalability and inconsistent responses across sensor samples. We introduce a transformative sensing platform that integrates large‐scale photonic multiplexing with data‐driven an...

Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed. Further, these thres...

Netlist Reverse Engineering (NRE) is a critical human-computer interaction task for identifying security threats at the microchip level. Yet, little is known about how individual factors shape NRE performance and practice effects. We conducted a mixed experimental and quasi-exper...

Abstract Southwest and Central Asia were pivotal regions for the domestication and dispersal of domestic herbivores. Here we investigate long-term variation in bony labyrinth morphology of domestic bovids (sheep, goats and cattle) across the last 10 000 years. We focused on the o...

Single-Domain Orbital Angular Momentum Mapping: Advancing Photoemission Dichroism to the Nanoscale
Abstract Circular dichroism in angle-resolved photoemission spectroscopy (CD-ARPES) is widely used to probe orbital angular momentum (OAM) and Berry-curvature-related phenomena in two-dimensional quantum materials. However, in many materials, conventional micron-scale measurement...

Feindbild postkoloniale Studien: imperiale Projektionen des (deutschen) Anti-Antisemitismus
Postcolonial studies emerged as a critical-emancipatory tradition of criticism that analyzes historical forms of imperialism and colonial forms of knowledge and practice (such as racist exclusions) as constitutive of Western modernity. By now, this tradition is often declared the...

Resolving the Nature of the Lowest-Frequency Raman Mode of Liquid Water
Abstract The lowest-frequency Raman mode of water, observed through depolarized light scattering or optical Kerr effect techniques, is routinely used to track dynamic changes of interfacial water near ions or biomolecules. Despite this broad importance, its microscopic origin and...

Directed Surface Immobilization of Coordination Cages for Host–Guest Studies
Abstract Self-assembled coordination cages are bioinspired host–guest systems mimicking natural nanoconfinements and their functions as receptors and reaction compartments. While such systems are conventionally studied in solution or as bulk materials, the examination of surface-...
