Earth observation (EO) is crucial for addressing environmental and societal challenges, but it struggles with revisit times and spatial resolution. The EU-funded SURPRISE project aims to improve EO capabilities by studying space instrumentation using compressive sensing (CS) implemented through spatial light modulators (SLMs) based on micromirror arrays (MMAs) to improve the ground sampling distance. In the SURPRISE project, we studied the development of an MMA that meets the requirements of a CS-based geostationary instrument working in the visible (VIS) and mid-infrared (MIR) spectral ranges. This paper describes the optical simulation procedure and the results obtained for analyzing the performance of such an MMA with the goal of identifying a mirror design that would allow the device to meet the optical requirements of this specific application.

The article presents a study on the importance of growth velocity data in managing patients with constitutional delay of growth and development (CDGD). The study noted that CDGD is found in both genetically short children and adolescents with familial short stature, as well as, those from tall statured families. According to the study, the lower growth rates presented in the 25th percentile of the growth velocity data can be an indicator of an underlying disorder such as hormonal imbalance, cystic fibrosis, or celiac disease.

Collagen was extracted by pepsin treatment from various tissues and skin fibroblasts of 23 patients belonging to different types of osteogenesis imperfecta (OI), and characterized by molecular sieve and ion exchange chromatography, gel electrophoresis, and amino acid analysis. We found an elevated collagen III/I ratio in the skin of one patient with OI type I but almost normal values in skin fibroblasts of two other patients of this OI type. Five patients with OI type II had a normal collagen III/I ratio in their skin and skin fibroblasts, but the degree of hydroxylation of lysine residues in collagen I and III from their skin, bone, calvarium, and noncalcified calvarial tissue was increased. Patients belonging to OI types II, III, and IV had also considerable amounts of collagen III in their long bones, while bone tissue from controls contained only type I collagen. The content of type V in calcified tissues was virtually the same in controls and patients. [ABSTRACT FROM AUTHOR]
