Luis Eduardo López-Vargas · Diego Jesús Macías-Pinto · Jhoy Fleming Córdoba-Calvo · Jorge Hernan Patiño Rodriguez

Sub-Andean forests of the Colombian Central Cordillera are among the most biodiverse and threatened Neotropical ecosystems, yet their floristic composition, vegetation structure, and aboveground carbon storage remain poorly documented. We characterized the floristic diversity, vegetation structure, and aboveground carb...

Noise suppression via pulsed all-optical magnetometry with nitrogen-vacancy ensembles

Xiechen Zheng · Jeyson T\'amara-Isaza · John Blanchard · Ronald Walsworth

Abstract All-optical (AO) microwave-free magnetometry using nitrogen-vacancy (NV) centers in diamond simplifies experimental design and broadens sample compatibility. While continuous-wave (cw) detection of AO photoluminescence (PL) changes is commonly employed, its performance is susceptible to systematic fluctuations...

It is seen in young adults, and only few pediatric cases have been reported so far. We report an 8-year-old boy presenting wi...

Persistent tissue hypoperfusion improves risk stratification beyond vasopressor dose in refractory septic shock: a secondary analysis of the ANDROMEDA-SHOCK-2 trial

Eduardo Kattan · Gustavo A. Ospina-Tascón · Nicolas Orozco · Jean-Louis Teboul · y 124 más

A recent Delphi consensus highlighted elements for defining refractory septic shock. We assessed whether integrating persistent tissue hypoperfusion with vasopressor dose after protocolized resuscitation improves mortality risk stratification compared with vasopressor dose alone.We performed an exploratory secondary an...
