Endogenous strategy spaces in sequential- and simultaneous-move duopoly games

Abstract Duopoly markets are widely discussed in industrial economics under the assumptions of quantity and price competition in sequential- and simultaneous-move duopoly games with differentiated goods. We compare Nash and Stackelberg equilibria in which the firms endogenously c...

Synthesis and Polymerization of a Lactone Building Block Derived From Cashew Nut Shells

The biorenewable feedstock cardanol, a phenol compound substituted with an unsaturated C15 hydrocarbon chain, was selectively transformed into a cyclohexanone derivative through partial hydrogenation. Subsequent conversion via Baeyer-Villiger oxidation (BVO) gave a lactone produc...

An ‘Empty’ [Fe 16 ] Cage and its Transformation into [Fe 17 ] and [Fe 30 ]

ABSTRACT Polymetallic clusters of Fe III constructed without organic bridging ligands are an emerging class of molecules with structures akin to iron oxide minerals, possessing large spin ground states and/or displaying spin frustration effects. All previous examples, [Fe 8 ], [F...

Multi-lemma representation of Mandarin noun-noun compounds in speech production: EEG evidence

This study investigated how noun-noun compounds and their syntactic properties are represented in production. Participants’ naming latencies and electrophysiological responses were analysed to investigate the classifier congruency effect in Mandarin Chinese (Wang, M., Chen, Y., &...

Changing Prescription Patterns in Pharmacologically Treated Patients with Newly Diagnosed Inflammatory Bowel Disease in German Gastroenterology Practices: A Real-World Study, 2015–2024

Background/Objectives: The therapeutic landscape of inflammatory bowel disease (IBD) has evolved, particularly with the expanding availability of biologic and targeted therapies. This study characterized real-world prescribing patterns among patients with newly diagnosed Crohn’s...

Ungrievable lives: State and non-state authoritarianism in the making of Uyghur foreign fighters

While there is a broad literature on the policies of authoritarian regimes toward their populations abroad, we know far less about the inclusionary and exclusionary policies of authoritarian host states toward displaced populations residing within their own territories. This arti...

From concept to action: Driving impact through responsible research practices in the International Polar Year 2032–2033 An early career perspective

Regions at the poles are warming at rates two to four times higher than the global average, driving profound environmental, societal, and geopolitical changes. As Polar Early Career Researchers with careers extending into and beyond the 5th International Polar Year in 2032–2033,...

Deep whole genome sequencing of epileptogenic brain lesions

Abstract Objective Malformations of cortical development and low‐grade epilepsy‐associated tumors often cause drug‐resistant lesional focal epilepsy (LFE) amenable to surgical treatment. Genetic testing of resected brain tissue can provide diagnostic and mechanistic information a...

Bone Radiopharmaceuticals: Evolution from Palliative Therapy to Targeted Precision Oncology and Theranostics

Bone radiopharmaceuticals have evolved from early palliative agents into integral components of targeted precision oncology and theranostics. This review comprehensively traces the historical trajectory, pathophysiological mechanisms, and clinical applications of bone-directed nu...

Reactivity of a Soft Indium‐Based Frustrated Lewis Pair Towards Alkynes

The geminal pyridine stabilized frustrated Lewis pair (FLP) t Bu 2 In(py)CH 2 P t Bu 2 ( 1 ·py) was reacted with various alkynes. 1 ·py does not react with PhC≡CH, however, it does with the unsymmetrically substituted PhC≡CSiMe 3 and p‐ Br‐C 6 H 4 C≡CSiMe 3 under reversible forma...

Halo mass functions in mixed cold and fuzzy dark matter models

Abstract We investigate the impact of mixed cold and fuzzy dark matter (referred to as MDM) cosmologies on the halo mass function (HMF) using numerical simulations performed with the AxiREPO framework. We consider models in which an ultralight axion-like component with mass m = 1...

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...

Who cares about Otto? The monument of Otto von Bismarck in Bielefeld between commemoration, forgetting, and intervention

Monuments remain physically present long after the commemorative practices and shared interpretations that once sustained them have eroded. This article examines this process through the history of the Bismarck monument in Bielefeld, Germany, from its inauguration in 1903 to the...

Research note on gravity artifact reduction in IMU signals using Madgwick orientation estimation

Abstract Objective Gravitational artifacts bias Inertial Measurement Unit (IMU) signals, complicating applications such as Seismocardiography (SCG). This study aimed to validate a gravity-artifact reduction algorithm using Madgwick orientation estimation in a controlled, physics-...

The Boolean spectrum of a Grothendieck category

Abstract A notion of support for objects in any Grothendieck category is introduced. This is based on the spectral category of a Grothendieck category and uses its Boolean lattice of localising subcategories. The support provides a classification of all subcategories that are clo...

Data for "The QCD phase diagram for three-flavor Möbius domain-wall fermions"

This dataset contains the processed numerical data and plotting scripts underlying the figures in the article "The QCD phase diagram for three-flavor Möbius domain-wall fermions". Each directory corresponds to one or more figures in the paper. The gauge-field ensembles and raw me...

Gatekeeping in the age of generative AI

Twenty years after open access transformed scholarly publishing, another game-changer in the form of generative AI emerged, bringing with it significant implications for the quality of the scholarly record. The peer-review system, which has long been the most important gatekeepin...

Achieving physiologic distensibility targets frequently requires modification of standard cruroplasty during anti-reflux surgery

Abstract Background Intraoperative EndoFLIP provides objective assessment of esophagogastric junction (EGJ) distensibility during anti-reflux surgery, and final distensibility index (DI) values of 2.0–3.5 mm 2 /mmHg have been associated with improved reflux control while minimizi...

Testing machine-learned distributions against Monte Carlo data for the QCD chiral phase transition

A bstract We demonstrate that conditional Masked Autoregressive Flows constitute a flexible interpolation tool for lattice QCD observables, conditioned on bare lattice parameters. As a benchmark, we use the chiral phase structure of QCD with five degenerate light quark flavours,...

Decoding the autotetraploid origin of the stress-tolerant wild beet Beta corolliflora

Abstract Background Most crop plants, including sugar beet ( Beta vulgaris subsp. vulgaris ), suffer from domestication bottlenecks and low genetic diversity caused by extensive selection for few traits. However, crop wild relatives (CWRs) harbour useful traits relevant for crop...
