Efficient simulation and calibration of the rough Bergomi model via Wasserstein distance

Changqing Teng · Guanglian Li

Despite the empirical success of the rough Bergomi (rBergomi) model in modeling volatility dynamics, its practical use remains challenging due to high computational complexity in both pricing and calibration arising from its non-Markovian structure. To address these difficulties, we develop an efficient computational f...

Multi-beam ptychographic tomography for rapid nano-imaging of technical catalysts on extended length scale

Mikhail LYUBOMIRSKIY · Tang LI · Leonardo ALMEIDA DE CAMPOS · Maik KAHNT · y 5 más

Multibeam X-ray ptychography, a recent innovation, offers substantial potential for replacing the conventional single-beam method. This technique maximizes synchrotron photon utilization, enabling significant gains in both scan field-of-view (FOV) and measurement speed, thus opening new avenues for functional studies....

Collection of some model compounds.

Francesco D ACAPITO · Simone AMATORI · Jacopo ORSILLI · Letizia MONICO

In this experimental session we will collect XAS spectra from different model compounds in order to carry out the analysis of previous data.

Low energy protein modes as indicators for pH dependent structural changes of iron-sulfur proteins

Volker SCHUENEMANN · Marco TUMMELEY · Lukas KNAUER · Konstantin GRÖPL · y 2 más

Using Nuclear Inelastic Scattering (NIS) we want to explore whether NIS-active protein modes can be used to investigate pH-dependent protonation effects. For that purpose we suggest to perform NIS experiments on the protein Apd1 which has an unusual 2Fe-2S cluster bound to the protein matrix via two cysteines and two h...

In situ restructuring of copper-based acetylene hydrochlorination catalysts

Dragos Constantin STOIAN · Vera GIULIMONDI (ORCID: 0000-0001-5996-657X) · Kenneth MARSHALL · Tangsheng ZOU · y 2 más

In this project, by combining quick X-ray absorption spectroscopy (XAS) with X-ray diffraction (XRD) measurements, we aim to probe dynamic changes to the speciation and local environment of distinct Cu (isolated atoms or nanoparticles) supported on activated carbon (AC) in the acetylene hydrochlorination reaction. The...

Relaxed Lagrangian Approach to First-Order Non-Convex Mean Field Type Control Problems

Mendico, Cristian · Wang, Kaizhi · Xu, Yuchen

We address the existence of equilibria for mean field type control problems of first-order with non-convex action functional. Introducing a relaxed Lagrangian approach on the Wasserstein space to handle the lack of convexity, we prove the existence of new relaxed Nash equilibria and we show that our existence result en...

De la identificación a la acción:: inventariado y jerarquización de recursos turísticos como claves para la planificación y gestión turística

Iria Caamaño-Franco · María Elvira Lezcano González · Begoña Muíño-Sar

This article develops a methodological model for the inventorying and prioritisation of tourism resources, conceived as a strategic tool for destination planning and management. The Eume region (Galicia, Spain) is adopted as a case study within the framework of its Destination Tourism Sustainability Plan, enabling a ri...

Decoupling the effects of disorder and density on the boson peak by probing a metal-organic framework glass

Alexander CHUMAKOV · Philip RASMUSSEN (ORCID: 0009-0005-7494-894X) · Søren Strandskov SØRENSEN · Jonas FINKLER (ORCID: 0000-0003-4970-575X) · y 1 más

Glass materials exhibit vibrational anomalies, including the "boson peak" (BP), characterized by an abundance of low-frequency vibrational modes beyond the expectation in the Debye model. The BP is often described to correlate with disorder and density, but usually these two parameters increase when going from the crys...

A systematic review of electrophysiological markers of reward processing in addiction

Anna Staniszewska · Mateusz Gola · Izabela Szumska

Prevalence of addictive behaviors is commonly associated with alterations in the brain's reward circuitry, leading to the upholding of a maladaptive pattern of reward-seeking behavior despite aversive consequences. The main objective of this systematic review was to provide a broad overview of the literature on electro...
