Understanding the effects of rotation on the wake of a wind turbine at high Reynolds number

Autor: Pique, Alexander, Miller, Mark A., Hultmark, Marcus

The wake of a horizontal-axis wind turbine was studied at $Re_D=4\times10^6$ with the aim of revealing the effects of the tip speed ratio, $\lambda$, on the wake. Tip speed ratios of $4<\lambda<7$ were investigated and measurements were acquired up t

Zero-shot Causal Graph Extrapolation from Text via LLMs

Autor: Antonucci, Alessandro, Piqué, Gregorio, Zaffalon, Marco

We evaluate the ability of large language models (LLMs) to infer causal relations from natural language. Compared to traditional natural language processing and deep learning techniques, LLMs show competitive performance in a benchmark of pairwise re

Abstract Wildlife tagging provides critical insights into animal movement ecology, physiology, and behavior amid global ecosystem changes. However, the stress induced by capture, handling, and tagging can impact post-release locomotion and activity a

Oncogenic role of PMEPA1 and its association with immune exhaustion and TGF-β activation in HCC

Publikováno v: JHEP Reports, Vol 6, Iss 11, Pp 101212- (2024)

Background & Aims: Transforming growth factor β (TGF-β) plays an oncogenic role in advanced cancer by promoting cell proliferation, metastasis and immunosuppression. PMEPA1 (prostate transmembrane protein androgen induced 1) has been shown to promo

FlowDrone: Wind Estimation and Gust Rejection on UAVs Using Fast-Response Hot-Wire Flow Sensors

Autor: Simon, Nathaniel, Ren, Allen Z., Piqué, Alexander, Snyder, David, Barretto, Daphne, Hultmark, Marcus, Majumdar, Anirudha

Unmanned aerial vehicles (UAVs) are finding use in applications that place increasing emphasis on robustness to external disturbances including extreme wind. However, traditional multirotor UAV platforms do not directly sense wind; conventional flow

Fast-response hot-wire flow sensors for wind and gust estimation on UAVs

Autor: Simon, Nathaniel, Piqué, Alexander, Snyder, David, Ikuma, Kyle, Majumdar, Anirudha, Hultmark, Marcus

Due to limitations in available sensor technology, unmanned aerial vehicles (UAVs) lack an active sensing capability to measure turbulence, gusts, or other unsteady aerodynamic phenomena. Conventional in situ anemometry techniques fail to deliver in

Assessing the Role of Wooden Vessels, Basketry, and Pottery at the Early Neolithic Site of La Draga (Banyoles, Spain)

Autor: Bertin Ingrid, Romero-Brugués Susagna, Tzerpou Evdoxia, Morera Núria, Théry-Parisot Isabelle, Piqué Raquel

Publikováno v: Open Archaeology, Vol 10, Iss 1, Pp 109-162 (2024)

Organic containers are rarely preserved in archaeological contexts. As a result, the work involved in their production and their functions remains invisible unlike other containers commonly better represented, such as pottery. The early Neolithic sit
