GBNL: Graded Betti number learning of complex biological data

Zia, Mushal · Suwayyid, Faisal · Wei, Guo-Wei

While persistent homology is widely used for data shape analysis, persistent commutative algebra (PCA) has seen limited adoption in machine learning and data science. Unlike persistent homology, which delivers topological invariants in the form of Betti numbers, PCA provides both algebraic invariants and graded Betti n...

Understanding timescales of ion-induced assembly of cellulose nanofibers with in-situ scanning SAXS

William CHEVREMONT · Jonas TEJBO (ORCID: 0009-0009-8589-865X) · Tomas ROSEN · Linn EKMAN · y 2 más

Controlled alignment and assembly of dispersed cellulose nanofibers (CNFs) can result in materials with impressive mechanical properties and provide biobased alternatives for many advanced materials today. To improve such processes, it is crucial to understand the timescales of ion-induced assembly and how these are af...

Dynamic multi-agent deep reinforcement learning-based pricing and incentivization approach in multimodal transportation networks

Khadidja Kadem · Mostafa Ameli · Carlos Lima Azevedo · Mahdi Zargayouna · y 1 más

In multimodal transportation systems, shared mobility services (SMSs) are promoted for their potential to enhance flexibility and reduce congestion. However, SMS demand is often concentrated in high-density areas, which can limit the effectiveness and accessibility for various commuter groups. This uneven integration c...

Investigation of dynamic phase transitions of highly active CO2 methanation LaNiO3 perovskite catalysts

Stefano SCOGNAMIGLIO · Spyridon ZAFEIRATOS · Clément MOLINET-CHINAGLIA · Davide SALUSSO · y 3 más

Cost efficient catalysts are in great demand for the CO2 hydrogenation into useful chemicals and fuels. Recently we prepared a high surface area LaNiO3 perovskite catalysts with up to 4 times higher activity than conventional Ni-supported on La2O3. Using in-situ NAP-XPS and XRD we demonstrated the transformation of LaN...

Distribution of deformed Laplacian limit points

Elismar R. Oliveira · Jonas Szutkoski · Vilmar Trevisan

This paper investigates limit points of the deformed Laplacian matrix, which merges the Laplacian and signless Laplacian matrices of a graph through a quadractic one-parameter family of matrices. First, we show that any value greater or equal to 1 is a deformed Laplacian limit point (for different values of the paramet...

Representations of spectrum of GL(m) type quantum matrices

Dimitry Gurevich · Pavel Saponov · Mikhail Zaitsev

In the present paper we are dealing with reflection equation algebras ${\cal L}(R)$ corresponding to even skew-invertible Hecke symmetries. Our main result consists in computing the characters of the spectral values of the generating matrix $L$ of ${\cal L}(R)$ in finite-dimensional representations labeled by partition...

On the local representation theory of symmetric groups

Tendi, Greta

Given a Sylow $p$-subgroup $P$ of a symmetric group, we describe the action of its normalizer on $\mathrm{Irr}(P)$. To this end, we establish a one-to-one correspondence between the irreducible characters of $P$ and certain equivalence classes of explicitly defined functions, which are also naturally suited to describi...

Growth and oelic acid adsoption on magnetite nanoparticles on STO (100)

Ming-Chao KAO (ORCID: 0000-0002-6443-214X) · Mona KOHANTORABI · Lucio MARTINELLI · Vedran VONK · y 4 más

We aim to explore the growth and epitaxy of magnetite nanoparticles on SrTiO3(100) (STO) by in-situ grazing incidence x-ray diffraction. We will monitor the role of temperature and oxygen pressure in growth, epitaxy and orientation of the nanoparticles. Form reciprocal space maps, we will elucidate the 3D shape of the...

Statistical Inference for Local Granger Causality

Liu, Yan · Taniguchi, Masanobu · Ombao, Hernando

Granger causality has been employed to investigate causality relations between components of stationary multiple time series. We generalize this concept by developing statistical inference for local Granger causality for multivariate locally stationary processes. Our proposed local Granger causality approach captures t...

Application for Renewal of Shock-BAG beam time at ESRF

Daniel EAKINS · Benoît CLEYET-MAREL · Jose Antonio RODRIGUEZ MARTINEZ · Jean-René BURIE · y 29 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...
