Numerical analysis of stochastic elliptic variational inequalities of the first kind

Chenhui Zhu · Fei Wang · Weimin Han

This paper presents a numerical approach to the stochastic obstacle problem using the stochastic Galerkin (SG) method. Due to the low regularity of the solution, linear finite elements are employed in both the physical and random variable spaces. Properties of random fields and variational inequalities of the first kin...

Removable singularities and Harnack inequality for nonlinear Hörmander degenerate subelliptic equations

Jiayi Qiang · Yawei Wei · Mengnan Zhang

This paper concerns the quasilinear subelliptic function derived from Hörmander vector fields. Based on the significant work of J. Serrin in \cite{SER}, M. Meier in \cite{MM1}, and L. Capogna, D. Danielli and N. Garofalo in \cite{LC1,LDN}, we obtain the removable singularities and Harnack inequality by a sharp Sobolev...

Temperature evolution of crystallographic parameters in tetragonal tungsten bronzes

Caren Regine ZEIGER · Tomasz POREBA · OLA GJONNES GRENDAL · Catherine DEJOIE · y 1 más

A large group of materials are known to crystallize in the tetragonal tungsten bronze (TTB) structure, having the general formula A12A24C4B12B28O30. Depending on the chemistry and structure a wide range of interesting magnetic and electronic properties are known to exist among these materials, including ferroelectricit...

Turismo y desigualdad urbana: una mirada a la experiencia urbana de los habitantes de La Paz, México

Mario Antonio Moreno Escobedo · Álvaro López López

Immersed in urban improvement processes driven by tourism, coastal cities face growing socio- spatial contradictions manifested in dynamics of fragmentation, polarisation, and inequality. The case of La Paz illustrates how touristification reconfigures urban space, prioritising the modernisation of the coastline whilst...

Austrian Crystallographic Diffraction Consortium

Sylvain ENGILBERGE · Andreas WINKLER · Eric RIVE-MATHIEU · Maximilian FUCHS

The Austrian Crystallographic Diffraction Consortium (ACDC) BAG aims at supporting several macromolecular structural biology groups across Austria (in total 20 research groups at 9 institutions in 4 cities). We employ mainly the technique of X-ray crystallography to characterize macromolecular biological complexes, but...

Gravitational perturbations of a regular T-dulatiy inspired black hole: Quasinormal modes, excitation factors, and time-domain evolution

Bekir Can Lütfüoğlu · Mardon Abdullaev · Javlon Rayimbaev · Shokhzod Jumaniyozov · y 1 más

We study axial gravitational perturbations of the neutral regular black hole generated by a non-local, T-duality-inspired zero-point length and the associated gravitational self-energy. In this geometry, the usual point source is replaced by a regular core, and the zero-point length controls the departure from the Schw...

Application for Renewal of Shock-BAG beam time at ESRF

Sourabh BHARDWAJ · Alexander Oliver RACK · Benjamin JODAR · Kassim MUGHAL · y 17 más

This proposal concerns renewal of the Shock block allocation group (BAG). As a reminder, the purpose of the Shock BAG is to coordinate and promote access to high-resolution X-ray imaging to further study of materials under rapid and extreme loading. The BAG pools together shared equipment, personnel and expertise to un...

Adapting the business model to ensure resilience: The case of michelin-starred french restaurants during the Covid-19 crisis

Coudeville, Calypso · Warnier, Vanessa · Demil, Benoît

The Covid-19 pandemic exposed the vulnerabilities of the fine-dining hospitality sector and reignited debates on organizational resilience. While the literature distinguishes operational, functional, and strategic resilience, it often conflates temporary business model adjustments enacted under crisis conditions with g...

Approximation of rearrangements by polarizations

Bianchi, Gabriele · Gardner, Richard J. · Gronchi, Paolo · Kiderlen, Markus

The symmetric decreasing rearrangement of functions on $\mathbb{R}^n$ features in several seminal inequalities, such as the Pólya-Szegő inequality. The latter was shown by the authors to hold for all smoothing rearrangements, a class that includes the more general $(k,n)$-Steiner rearrangement, as well as others introd...
