Sparse Estimators and the Oracle Property, or the Return of Hodges' Estimator

open access: yes, 2007
We point out some pitfalls related to the concept of an oracle property as used in Fan and Li (2001, 2002, 2004) which are reminiscent of the well-known pitfalls related to Hodges' estimator.

Digital Surface‐Enhanced Raman Scattering With Event Counting and Spectrum Learning for Label‐Free Protein Quantification

open access: yesAdvanced Intelligent Systems, EarlyView.
A statistical and machine learning‐assisted surface‐enhanced Raman scattering (SERS) framework is developed for label‐free quantification of low‐abundance analytes, including proteins. Combining digital SERS event counting with binomial regression and an artificial neural network (ANN) trained on full spectra, the approach achieves picomolar detection ...

B/ordering and healthcare access for migrants with precarious status: The role of healthcare workers in counteracting restrictive policies

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract In Canada, precarious migration is largely invisibilized. Nonetheless, b/ordering greatly affects people's realities by limiting access to social rights. In Quebec, migrants with precarious status (MPS) do not have access to healthcare, although Quebec has a “universal” healthcare coverage.

Wireless blood pressure sensor implantation in sheep: A detailed technique

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.

Small vesicles, big potential: A review of innovative exosome delivery and molecular mechanisms in preclinical myocardial infarction models

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This narrative review discusses animal models of exosome‐based myocardial infarction treatments. Emerging techniques aim to improve exosome stability, targeting, and bioavailability for MI treatment as drug delivery vehicles and regenerative mediators that promote myocardial regeneration. Abstract Exosomes have emerged as promising therapeutic carriers,
