Dimension of inhomogeneous sub-self-similar sets

Dubey, Shivam · Verma, Saurabh

In this paper, we introduce the concept of Inhomogeneous sub-self-similar (ISSS) sets, building upon the foundations laid by Falconer (Trans. Amer. Math. Soc. 347 (1995) 3121-3129) in the study of sub-self-similar sets and drawing inspiration from Barnsley's work on inhomogeneous self-similar sets (Proc. Roy. Soc. Lond...

TopiCLEAR: Adaptive embedding clustering for interpretable topic discovery from short texts

Aoi Fujita · Taichi Yamamoto · Yuri Nakayama · Ryota Kobayashi

Topic discovery is a fundamental technique for text mining that identifies abstract topics within large document collections. A recent approach to topic discovery is to cluster document or sentence embeddings, typically obtained from pre-trained language models, and represent each cluster as a topic. Despite their stro...

Ute KRENGEL · Montserrat Canals MATEU · Andrew MCCARTHY

The fourteen PIs associated to this proposal represent the entire crystallography community in Norway and are affiliated to the major Norwegian universities. The research interests of the PIs and their collaborators revolves around topics linked to structural biology and material sciences. We apply for beam time for si...

Formulation-dependent physicochemical properties and biological response of DOPC liposomes encapsulating Opuntia stricta extracts

Ahlem Ben Saad · Michela Tozzi · Flaminia Cesare Marincola · Franca Piras · y 7 más

The development of liposomes for the delivery of chemically labile natural extracts is often limited by extract instability and poorly controlled biological responses. In this study, zwitterionic 1,2-dioleoyl- sn -glycero-3-phosphocholine (DOPC) liposomes were engineered as platforms for the encapsulation of aqueous ex...

Lead halide perovskite crystallization in-situ during spin- coating.

Leonard SIMEONOV · Oleg KONOVALOV · Damian BALAZ · Lena MERTEN · y 3 más

Hybrid perovskite structures are promising materials for inexpensive and efficient solar cells. In particular formamidinium lead triiodide (FAPbI3) perovskite has shown to be a promising material for single-junction solar cells, reaching a certified power conversion efficiency of over 25%. However, FAPbI3 solar cells f...

Optimal control of infinite-dimensional dissipative systems

Hastir, Anthony · Reis, Timo

We study the linear-quadratic optimal control problem for infinite-dimensional dissipative systems with possibly indefinite cost functional. Under the assumption that a storage function exists, we show that this indefinite optimal control problem is equivalent to a linear-quadratic optimal control problem with a nonneg...

Unraveling synergistic effects in dual atom catalysts by operando XAS

Biagio DI VIZIO · Chiara MAURIZIO · Vinod PAIDI · Nicolò ROSSETTI · y 1 más

Dual Atom catalysts (DACs) have the potential to to achieve exceptional activity in many reactions including the oxygen evolution reaction, which is essential for the efficient production of green hydrogen from water electrolysis. DACs based on environmental friendly materials can be produced starting from single metal...

Pressure Temperature evolution of the Charge density wave and structural transition of the superconducting trilayer Nickelate La4Ni3O10

Alain PAUTRAT · Pierre TOULEMONDE · Olivier PEREZ · Gaston GARBARINO · y 3 más

La4Ni3O10 develops below 140K an incommensurate Charge and itinerant Spin density wave with qc=0.24b* which is believed to be associated to the Nickel atoms. Under pressure, a superconducting pocket appears above Pc=15GPa with a maximum of critical temperature up to 30K. A possible structural change due to a tilt of th...

Mass photometry and its expanding role in membrane protein research: The Torpedo marmorata nicotinic acetylcholine receptor as case study

Delaux, Sarah · Le Mouël, Korantin · Barilone, Nathalie · Castel, Jerome · y 5 más

Integral membrane proteins (IMPs) are challenging, yet highly relevant targets for structural biology. Selection of the appropriate membrane mimic environment necessitates extensive optimization using a combination of biochemical and biophysical techniques. We report here on the expanding role of mass photometry (MP) a...
