Omni‐directional Relief Impostors

open access: yesComputer Graphics Forum, 2007
Abstract Relief impostors have been proposed as a compact and high‐quality representation for high‐frequency detail in 3D models. In this paper we propose an algorithm to represent a complex object through the combination of a reduced set of relief maps. These relief maps can be rendered with very few artifacts and no apparent deformation from any view

Protein‐Template Gold Nanoclusters Induce Differentiation and Modify the Functional Properties of Primary Astrocytes

open access: yesAdvanced NanoBiomed Research, EarlyView.
The incubation of primary astrocytes with fAuNCs‐BSA induces: (A) long‐term effects including fAuNCs‐BSA internalization, red cell fluorescence, differentiation, upregulation of Ca2+ signaling, Cl‐current, and cell volume regulation. B) Short‐term (200 ms) stimulation with UV LED light increases in Ca2+ signaling and inhibition of K+ current. Astrocyte

Evaluating and leveraging large language models in clinical pharmacology and therapeutics assessment: From exam takers to exam shapers

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims In medical education, the ability of large language models (LLMs) to match human performance raises questions about their potential as educational tools. This study evaluates LLMs' performance on Clinical Pharmacology and Therapeutics (CPT) exams, comparing their results to medical students and exploring their ability to identify poorly formulated

A Framework to Illustrate Kinematic Behavior of Mechanisms by Haptic Feedback [PDF]

open access: yes, 2006
The kinematic properties of mechanisms are well known by the researchers and teachers. The theory based on the study of Jacobian matrices allows us to explain, for example, the singular configuration.

Spectroscopic Insights Into the Role of the Coverage of *CO and *H on Bifurcation of Ethylene and Ethanol Pathways in Carbon Dioxide Electroreduction

open access: yesCarbon Energy, EarlyView.
Zhao et al. control the coverage of *CO or *H intermediates by introducing foreign metal into Cu nanoparticles. The increased *CO coverage on Ag‐doped and Zn‐doped Cu promotes the generation of multi‐carbon products while the increased *H coverage of Co‐doped and Pd‐doped Cu enhances the selectivity of oxygenates. ABSTRACT As key reaction intermediates

Pancreatic Adenocarcinoma: Diagnosis by Ultrasound‐Guided Fine‐Needle Aspiration—Cyto‐Histological Correlation and Experience at a Multidisciplinary Tertiary Reference Center

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Background Pancreatic adenocarcinoma (PDAC) is characterized by its poor prognosis. Cytology is essential for diagnostic confirmation and ancillary studies. The endoscopic ultrasound (EUS) set a precedent, facilitating cytological sampling through fine‐needle aspiration (FNA), with a sensitivity of 93% and a specificity of 95%.
