Bayesian multi-exposure image fusion for robust high dynamic range ptychography.

The limited dynamic range of the detector can impede coherent diffractive imaging (CDI) schemes from achieving diffraction-limited resolution. To overcome this limitation, a straightforward approach is to utilize high dynamic range (HDR) imaging through multi-exposure image fusion (MEF). This method involves capturing measurements at different exposure times, spanning from under to overexposure and fusing them into a single HDR image.

Liver, NAFLD and COVID-19.

Coronavirus disease 2019 (COVID-19) is characterized by a wide clinical spectrum that includes abnormalities in liver function indicative of liver damage. Conversely, people with liver diseases are at higher risk of severe COVID-19. In the current review, we summarize first the epidemiologic evidence describing the bidirectional relationship between COVID-19 and liver function/liver diseases.

Fluoride: changes in knowledge and prescription habits of paediatricians for 11 years in Brittany, France.

Aims: To assess via a questionnaire the changes in knowledge and prescription habits for systemic fluoride of physicians at maternal and infant protection centres (MIP) and paediatricians in private practice (PPP) in the Brittany region between 2003 and 2014.

Methods: In both 2003 and 2014, the same seven-question survey was mailed to PPP (110 in 2003 and 101 in 2014) and MIP (61 in 2003 and 71 in 2014). An eighth question was added in 2014 about French guidelines published in 2008 (AFSSAPS guidelines).

Modeling sustainable reuse of nitrogen-laden wastewater by poplar.

Numerical modeling was used to simulate the leaching of nitrogen (N) to groundwater as a consequence of irrigating food processing wastewater onto grass and poplar under various management scenarios. Under current management practices for a large food processor, a simulated annual N loading of 540 kg ha(-1) yielded 93 kg ha(-1) of N leaching for grass and no N leaching for poplar during the growing season. Increasing the annual growing season N loading to approximately 1,550 kg ha(-1) for poplar only, using "weekly", "daily" and "calculated" irrigation scenarios, yielded N leaching of 17 kg ha(-1), 6 kg ha(-1), and 4 kg ha(-1), respectively.

Enhanced vadose zone nitrogen removal by poplar during dormancy.

A pilot-scale, engineered poplar tree vadose zone system was utilized to determine effluent nitrate (NO3(-)) and ammonium concentrations resulting from intermittent dosing of a synthetic wastewater onto sandy soils at 4.5°C. The synthetic wastewater replicated that of an industrial food processor that irrigates onto sandy soils even during dormancy which can leave groundwater vulnerable to NO3(-) contamination.
