Entangled spin states are created by implanting muons into single-crystal LiY_{0.95}Ho_{0.05}F_{4} to form a cluster of correlated, dipole-coupled local magnetic moments. The resulting states have well-defined energy levels allowing experimental manipulation of the state populations by electromagnetic excitation. Experimental control of the evolution of the muon spin polarization is demonstrated through application of continuous, radio-frequency electromagnetic excitation fields. A semiclassical model of quantum, dipole-coupled spins interacting with a classical, oscillating magnetic field accounts for the muon spin evolution. On application of the excitation field, this model shows how changes in the state populations lead to the experimentally observed effects, thus enabling a spectroscopic probe of entangled spin states with muons.

Background: In pediatric intensive care units, pain, sedation, delirium, and iatrogenic withdrawal syndrome (IWS) must be managed as interrelated conditions. Although clinical practice guidelines (CPGs) exist, new evidence needs to be incorporated, gaps in recommendations addressed, and recommendations adapted to the European context.
Objective: This protocol describes the development of the first patient- and family-informed European guideline for managing pain, sedation, delirium, and IWS by the European Society of Paediatric and Neonatal Intensive Care.

It is helpful for diagnostic purposes to improve our current knowledge of gut development and serum biochemistry in young piglets. This study investigated serum biochemistry, and gut site-specific patterns of short-chain fatty acids (SCFA) and expression of genes related to barrier function, innate immune response, antioxidative status and sensing of fatty and bile acids in suckling and newly weaned piglets. The experiment consisted of two replicate batches with 10 litters each.

Importance: Adolescents account for almost half of the 2.5 million diagnosed sexually transmitted infections in the US annually, and the emergency department functions as the primary source of health care for many adolescents. No recommendations exist for emergency department gonorrhea and chlamydia screening.

Importance: For the first time in nearly 2 decades, the US infant mortality rate has increased, coinciding with a rise in overdose-related deaths as a leading cause of pregnancy-associated mortality in some states. Prematurity and low birth weight-often linked to opioid use in pregnancy-are major contributors.
Objective: To assess the health and economic impact of perinatal opioid use disorder (OUD) treatment on maternal and postpartum health, infant health in the first year of life, and infant long-term health.
