Protostellar half-life: new methodology and estimates [PDF]
A&A 618, A158 (2018), 2018 (Abridged) Protostellar systems evolve from prestellar cores, through the deeply embedded stage and then disk-dominated stage, before they end up on the main sequence. Knowing how much time a system spends in each stage is crucial for understanding how stars and associated planetary systems form, because a key constraint is the time available to form ...

Precise measurement of the 222Rn half-life: a probe to monitor the stability of radioactivity [PDF]
, 2015 We give the results of a study on the 222Rn decay we performed in the Gran Sasso Laboratory (LNGS) by detecting the gamma rays from the radon progeny. The motivation was to monitor the stability of radioactivity measuring several times per year the half-life of a short lifetime (days) source instead of measuring over a long period the activity of a ...

The Cyclic Antimicrobial Peptide C-LR18 Has Enhanced Antibacterial Activity, Improved Stability, and a Longer Half-Life Compared to the Original Peptide. [PDF]
Antibiotics (Basel)Background: LR18 is an α₋helical AMP with high antimicrobial activity, low hemolytic activity, and low cytotoxicity. However, the susceptibility to degradation of the peptidase enzyme and a short half-life hinder its application as a therapeutic agent ...

The αSynuclein half-life conundrum [PDF]
Neurobiology of DiseaseαSynuclein (αSyn) misfolding and aggregation frequently precedes neuronal loss associated with Parkinson's Disease (PD) and other Synucleinopathies. The progressive buildup of pathological αSyn species results from alterations on αSyn gene and protein ...
