Three-dimensional multilayer concentric bipolar electrodes restrict spatial activation in optic nerve stimulation

Diego Ghezzi, Eleonora Borda, Marta Jole Ildelfonsa Airaghi Leccardi, Vivien Gaillet, Elodie Geneviève Zollinger, Ricardo Camilo Moreira

Objective. Intraneural nerve interfaces often operate in a monopolar configuration with a common and distant ground electrode. This configuration leads to a wide spreading of the electric field. Therefore, this approach is suboptimal for intraneural nerve ...

Microstructural developments of limestone calcined clay cement (LC3) pastes after long-term (3 years) hydration

Karen Scrivener, Franco Alberto Zunino Sommariva

LC3 is one of the most promising alternatives for a high-performance blended cement with a significantly lower clinker content and with potential for worldwide adoption. For this reason, understanding its long-term performance is relevant to ensure service ...

Continual Test-Time Domain Adaptation

Olga Fink, Qin Wang

Test-time domain adaptation aims to adapt a source pretrained model to a target domain without using any source data. Existing works mainly consider the case where the target domain is static. However, real-world machine perception systems are running in n ...

Hypothalamic pregnenolone mediates recognition memory in the context of metabolic disorders

Maria del Carmen Sandi Perez, Ioannis Zalachoras, Sara Ramirez Flores

Obesity and type 2 diabetes are associated with cognitive dysfunction. Because the hypothalamus is implicated in energy balance control and memory disorders, we hypothesized that specific neurons in this brain region are at the interface of metabolism and ...

Photosynthetic acclimation and sensitivity to short- and long-term environmental changes in a drought-prone forest

Charlotte Grossiord

Future climate will be characterized by an increase in frequency and duration of drought and warming that exacerbates atmospheric evaporative demand. How trees acclimate to long-term soil moisture changes and whether these long-term changes alter trees' se ...

Structure-preserving approaches and data-driven closure modeling for model order reduction

Nicolò Ripamonti

In this thesis, we propose model order reduction techniques for high-dimensional PDEs that preserve structures of the original problems and develop a closure modeling framework leveraging the Mori-Zwanzig formalism and recurrent neural networks. Since high ...

eNAMPT actions through nucleus accumbens NAD + /SIRT1 link increased adiposity with sociability deficits programmed by peripuberty stress

Johan Auwerx, Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Simone Astori, Marie-Isabelle Guillot de Suduiraut, João Pedro de Matos Rodrigues, Wei Huang, Ioannis Zalachoras, Sriparna Ghosal

Obesity is frequently associated with impairments in the social domain, and stress at puberty can lead to long-lasting changes in visceral fat deposition and in social behaviors. However, whether stress-induced changes in adipose tissue can affect fat-to-b ...

Population-scale dietary interests during the COVID-19 pandemic

Robert West, Kristina Gligoric

The SARS-CoV-2 virus has altered people's lives around the world. Here we document population-wide shifts in dietary interests in 18 countries in 2020, as revealed through time series of Google search volumes. We find that during the first wave of the COVI ...

Molecular Regulation of Muscle Stem Cell Fate during Skeletal Muscle Regeneration and Aging

Sara Ancel

Muscle stem cells (MuSCs) are the primary source of myogenic progenitors during muscle repair and are essential for the long-term regenerative capacity of skeletal muscle. Following myofiber injury, MuSCs transition from a quiescent to an activated state, ...
