Exploring Domain Switching Dynamics and Phase Configuration in Ferroelectrics

Markys CAIN · Julia PAVLOVA · Jakub KOLACZ · Thomas MION · y 2 más

In situ synchrotron diffraction study will be used to identify and track multiple phases in single crystals of the mixed perovskite PIN-PMN-PT as a function of electric field and external mechanical stress in dynamic mode. We we will exploit the unique capabilities of the BM28 beamline to perform X-ray dynamic diffract...

FDFT1 is associated with ovarian reserve and regulates proliferation and steroidogenesis in the human granulosa cell line KGN via the AKT/mTOR signaling pathway

Xin, Zhang · Peng, Liu · Yunxiu, Tan · Xiaolei, Liang · y 1 más

Diminished ovarian reserve (DOR) leads to decreased ovarian endocrine function and reduced fertility in women, contributing to infertility. Dysregulated lipid metabolism can impair normal follicular development by interfering with cholesterol metabolism and hormone synthesis, thereby contributing to DOR. Farnesyl-dipho...

Unveiling the interplay between Copper and Heme binding to Hemopexin

ENRICO FALCONE · Francesco STELLATO · Olivier PROUX · Emiliano DE SANTIS

Hemopexin (Hpx) is a plasma glycoprotein with very high affinity for heme. It can mitigate heme-mediated oxidative stress and cardiovascular dysfunction and has promising therapeutic applications for hemolytic disorders. The uptake of heme-Hpx is accompanied by an increase in intracellular Cu levels, thus hinting at a...

Stability assessment considering multi-timescale power system dynamics: Insights into Hopf bifurcations with GFL and GFM IBRs

Luis David Pabón Ospina · Martin Braun · Sushobhan Chatterjee · Sijia Geng

Real power systems exhibit dynamics that evolve across a wide range of timescales, from very fast to very slow phenomena. Historically, incorporating these wide-ranging dynamics into a single model has been impractical. As a result, power engineers rely on timescale decomposition to simplify models. When evaluating fas...

Enhancing scientific named entity recognition via large language models: a type-driven multi-task learning approach

Tong Bao · Yi Zhao · Heng Zhang · Chengzhi Zhang

Scientific named entity recognition (SciNER) plays a crucial role in information extraction and knowledge discovery from scientific texts. Recently, large language models (LLMs) have demonstrated the capacity to achieve competitive SciNER performance with minimal human effort. Existing research highlights the importanc...

Are sparse graphs typically determined by their spectrum?

Van de Berg, Nils · Van Werde, Alexander

We investigate whether it is typical for a sparse graph to be uniquely characterized by its adjacency spectrum up to isomorphism. Our first result shows that the giant component of an Erdős-Rényi graph is cospectral when the average degree is sufficiently small. The proof relies on the existence of a specific pendant t...

Development of industrial Artificial-Intelligence systems in production environments: A Delphi study on benefits, issues, risks, and mitigation strategies

Richard May · Leonard Cassel · Hashir Hussain · Muhammad Talha Siddiqui · y 3 más

The adoption of industrial Artificial-Intelligence (AI) systems in production environments has increased considerably in recent years, enabling new forms of process automation, engineering support, and data-driven decision making. However, practitioner-oriented insights regarding their practical development, configurat...

Lower order term for the fractional Laplacian with a Hardy potential

Rubén Fiñana · Alexis Molino

This paper is concerned with the following semilinear elliptic equation involving the fractional Laplacian: $$(-Δ)^s u+ g|u|^{p-1}u= λ\frac{u}{|x|^{2s}}+f(x),$$ in a bounded domain $Ω$ of $\mathbb{R}^N\,(N>2s)$, subject to the zero Dirichlet condition in $\mathbb{R}^N\setminus Ω$, where $01$ and $f\in L^{(p+1)/p}_g(Ω)$...

Data-driven perimeter control: A Zürich case study

Alessio Rimoldi · Carlo Cenedese · Alberto Padoan · Florian Dörfler · y 1 más

Urban traffic congestion is a key challenge for the development of modern cities, requiring advanced control techniques to optimize existing infrastructure usage. Despite the extensive availability of data, modeling such complex systems remains an expensive and time-consuming step when designing model-based control app...
