A novel central line securement vest reduces line trauma and improves quality of life in patients with intestinal failure

JPGN Reports, EarlyView.
Abstract Objective We sought to assess the impact of a novel central line securement vest on the rate of line complications (trauma, infections, and replacements), and measures of quality of life (QOL) in pediatric patients with intestinal failure. Methods We enrolled patients at a single tertiary pediatric center.

A Field Guide for Soil Erosion Risk Assessment in Olive Orchards Across Mediterranean Conditions for End‐Users and Stakeholders

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion control poses a crucial challenge to the sustainability of Mediterranean olive groves. To facilitate field‐level decision‐making, we have developed a field guide oriented to use in any type of olive orchard across the Mediterranean.

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

Limnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Optically Bound Rapid Plasmonic Nanorod Dimers: Anisotropic Dynamics Driven by Light‐Fluidic Cooperation

Laser &Photonics Reviews, EarlyView.
Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.

Rigorous Electromagnetic Quasinormal‐Mode Method Made Easy for Users

Laser &Photonics Reviews, EarlyView.
We present a method that combines numerical techniques with accurate approximations to enable simple and ultrafast computations of the scattered field based on quasinormal modes expansions. The method is made available in the open‐source package MANlite implemented within COMSOL.
