Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis
Laser &Photonics Reviews, EarlyView.We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

La sociologie peut-elle ignorer la phylogenèse de l'esprit ?
Sociologies, 2012 This article discusses the arguments that Albert Ogien and Louis Quéré direct against social naturalism, i.e. the metatheoretical project of integrating the empirical evidence and theoretical considerations from evolutionary biology and the cognitive ...

Peskine Sixfolds and Debarre–Voisin Fourfolds With Associated Cubic Fourfolds
Mathematische Nachrichten, EarlyView.ABSTRACT We develop the notion of Peskine sixfolds with associated K3 surfaces and cubic fourfolds and work out numerical conditions for when these associations occur. In discriminant 24, the first family for which there is an associated cubic fourfold, we identify the cubic explicitly.

Clique Irreducibility and Clique Vertex Irreducibility of Graphs
, 2009 A graphs G is clique irreducible if every clique in G of size at least two,has an edge which does not lie in any other clique of G and is clique reducible if it is not clique irreducible.

Purely Coclosed G2‐Structures on Nilmanifolds—II
Mathematische Nachrichten, EarlyView.ABSTRACT This paper completes the classification of seven‐dimensional nilpotent Lie groups endowed with a left‐invariant purely coclosed G2$\text{G}_2$‐structure, initiated in Bazzoni et al. [Mathematische Nachrichten 296 no. 6 (2023): 2236–2257], the authors provided the classification of decomposable seven‐dimensional nilpotent Lie groups and of the ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Spin density‐weighted (SDW) and inversion recovery (IR) 23Na MRI provide different sodium contrasts with complementary information. Therefore, the aim was to develop a time‐efficient sequence scheme capable of providing both contrasts by acquiring SDW and IR 23Na MRI data within a single sequence without additional measurement time ...

On the Irreducibility of Some Composite Polynomials
Journal of Mathematical Extension, 2012 . In this paper we study the irreducibility of some composite polynomials, constructed by a polynomial composition method over finite fields. Finally, a recurrent method for constructing families of irreducible polynomials of higher degree from given ...

Intrinsic value and its commitments: a response to the Conguillío Statement
Oikos, EarlyView.The Conguillío Statement asserts that ecosystems possess intrinsic value and presents this claim as part of the normative responsibilities of ecologists. Although such language is common in ecology, it is rarely accompanied by a sustained philosophical defense. This paper clarifies what would be required for the claim to succeed.

Technical wildness: Modernity, romanticism, and the technocratic turn in Scottish rewilding
People and Nature, EarlyView.Abstract Technical wildness is a new and increasingly influential culture of nature. This paper marks its emergence in Scotland in the early 2020s. Focusing on Scotland's rapidly evolving land management sector, the paper traces how private rewilding companies position science‐led land management and natural capital markets as the most effective ...
