Strict positive definiteness in geostatistics [PDF]
, 2017 Geostatistical modeling is often based on the use of covariance functions, i.e., positive definite functions. However, when interpolation problems have to be solved, it is advisable to consider the subset of strictly positive definite functions. Indeed,

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.Abstract Canning color retention is a key quality trait in dry bean (Phaseolus vulgaris L.) breeding, influencing consumer acceptance and commercial value. Public breeding programs maintain canning quality as a selection trait of importance, but existing color evaluation methods such as visual rating are subjective, while instrument colorimetry is ...

On space-time variograms: estimation and modeling choices [PDF]
, 2007 Space-time correlation modeling is one of the crucial steps of traditional structural analysis, since spacetime models are used for prediction purposes. There are significant problems to overcome in both the estimation and the modeling stages for space-

Slow exposure and the surfacing of the mask
piano b, 2016 The so-called “bulb mode” is the possibility a photographer has to slow down the shutter speed when in need of a very long exposure. Starting from this technical element typical of the photographic language, the paper compares two experiences linked to ...

Clinical Case Reports, Volume 14, Issue 8, August 2026.Current clinical practice for atrophic scars typically delays intervention until scar stabilization, usually 6–12 months after injury. This case presents a young male with an immature atrophic facial scar who received intradermal autologous platelet‐containing plasma (ACP) 2 months after injury.

Evaluating Sleep Apnea: In‐Lab Versus at‐Home Recording Time and the Impact of Positional Disease
The Laryngoscope, Volume 136, Issue 8, Page 3639-3647, August 2026.We evaluated the minimum recording time needed for in‐lab polysomnography (PSG1) and home sleep apnea test Type 3 portable monitoring (HSAT) to accurately reflect the full‐night apnea–hypopnea index (AHI) in patients with suspected obstructive sleep apnea (OSA).
