Prolonged Prophylactic Antibiotics Based on Preoperative Bile Culture Reduce Surgical Site Infections After Pancreaticoduodenectomy Following Preoperative Biliary Drainage: A Propensity‐Matched Analysis

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Objective The optimum duration of prophylactic antibiotics after pancreaticoduodenectomy following preoperative biliary drainage to prevent surgical site infections remains controversial. We evaluate whether a prolonged course of prophylactic antibiotics reduces surgical site infection after pancreaticoduodenectomy following biliary drainage ...

Model‐based fault diagnosis in closed‐loop safety‐critical chemical reactors: An experimental study

AIChE Journal, EarlyView.
Abstract This experimental study investigates fault detection and estimation in a continuous stirred‐tank reactor (CSTR) system under closed‐loop feedback control, including an analysis of different manipulative inputs for temperature regulation. A novel fault diagnosis approach is proposed, combining residual signal analysis and T2 statistic for real ...

Domesticating forests : how farmers manage forest resources [PDF]

, 2005
Local people in South-east Asia are often cited as skilled forest managers. It is barely acknowledged that an essential part of this forest management does not concern natural forests, but forests that have been planted, often after the removal of pre ...

Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Magnetic Fluid‐Driven Vine Robots for Minimally Invasive Tissue Biopsy Sampling

Advanced Intelligent Systems, EarlyView.
This study introduces a magnetic fluid‐powered vine robot for minimally invasive biopsies. The robot uses fluid pressurization for locomotion and external magnetic fields for precise steering. Its soft structure and high magnetic volume ensure controlled movements and stabilization, enabling effective tissue penetration.

Ligand Type Guided Keto‐Arylation Enables Modular Total Synthesis of Polycyclic CBS Xanthones

Angewandte Chemie, EarlyView.
A ligand type concept guided a central aromatic keto‐arylation in the first total syntheses of CBS72, CBS87 and CBS100. Davis oxidation with catalytic base and late‐stage aminolysis completed the route. This strategy provides modular, concise and high‐yielding access to uncharted polycyclic xanthones. Meanwhile, ligand types emerge as a powerful design

Lithium phosphonate umpolung catalysts: Do fluoro substituents increase the catalytic activity?

Beilstein Journal of Organic Chemistry, 2011
Fluorinated and nonfluorinated phosphonates are employed as precatalysts in lithium phosphonate catalyzed cross benzoin couplings. Surprisingly, a decreased catalytic activity for the fluorinated precatalysts compared to the nonfluorinated systems is ...

Classification of Pulmonary Nodules Using Multimodal Feature‐Driven Graph Convolutional Networks with Specificity Proficiency

Advanced Intelligent Systems, EarlyView.
The radiomics feature could save the storage space of all medical samples; on the other hand, it avoids data leakage. Graph convolutional neural networks could summarize the similarity of benign and malignant pulmonary nodules to improve the performance in distinguishing them with radiomics and common clinical features.
