Global sensitivity analysis of the A-SCOPE model in support of future FLEX fluorescence retrievals

2014

In support of ESA's Earth Explorer 8 candidate mission FLEX (FLuorescence EXplorer), a Photosynthesis Study has been initiated to quantitatively link fluorescence to photosynthesis. This led to the development of A-SCOPE, a graphical user interface software package that integrates multiple biochemical models into the soil-vegetation-atmosphere-transfer model SCOPE. Its latest version (v1.53) has been successfully verified and was subsequently evaluated through a global sensitivity analysis. By using the method of Saltelli [4], the relative importance of each input variable to model outputs was quantified through first order and total effect sensitivity indices. Variations in leaf area index…

Prototyping algorithm for retrieving FAPAR using MSG data in the context of the LSA SAF project

2007

This paper describes the prototyping algorithm developed for retrieving the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) using MSG data in the framework of satellite application facility on land surface analysis (LSA SAF). The prototyping relies on the Roujean and Breon (1995) method, which is based on simulations of visible and near infrared reflectance values in an optimal geometry. A relationship is found between a vegetation index and daily FAPAR The algorithm has been applied to one year of MSG BRDF data since August 2005, using a temporal frequency of 5-days, and then validated against a set of operational satellite FAPAR products such as MODIS, MERIS, SeaWiFS and …

Quantitative Multispectral Imaging Differentiates Melanoma from Seborrheic Keratosis.

2021

Melanoma is a melanocytic tumor that is responsible for the most skin cancer-related deaths. By contrast, seborrheic keratosis (SK) is a very common benign lesion with a clinical picture that may resemble melanoma. We used a multispectral imaging device to distinguish these two entities, with the use of autofluorescence imaging with 405 nm and diffuse reflectance imaging with 525 and 660 narrow-band LED illumination. We analyzed intensity descriptors of the acquired images. These included ratios of intensity values of different channels, standard deviation and minimum/maximum values of intensity of the lesions. The pattern of the lesions was also assessed with the use of particle analysis. …

Seismic anisotropy and its impact on imaging the shallow Alpine Fault : an experimental and modeling perspective.

2020

The transpressional Alpine Fault in New Zealand has created a thick shear zone with associated highly anisotropic rocks. Low seismic velocity zones (LVZ) and high seismic reflectivity are recorded in the Alpine Fault Zone, but no study has explored the underlying physical rock parameters of the shallow crust that control these observations. Protomylonites are the volumetrically dominant lithology of the fault zone. Here we combine experimental measurements of P‐wave speeds with numerical models of elastic wave anisotropy of protomylonite samples to explore how the fault zone can be seismically imaged. Numerical models that account for the porosity‐free real samples' fabric elastic tensors f…

Using the Reflective Journal to Improve Practical Skills Integrating Affective and Self-Critical Aspects in Impoverished International Environments. …

2021

The reflective practice journal is a teaching methodology that facilitates the acquisition of professional, attitudinal values and skills, affording comprehensive training by reflecting on experiences that have been lived and showing feelings that, a priori, would be hidden. Our aim was to implement it in the international practicum in impoverished environments as a facilitating instrument of meaningful learning and the acquisition of professional skills, integrating affective and self-critical aspects. The project was developed with Nursing students at Catholic University of Valencia, in an impoverished environment. Qualitative reflections increased, highlighting humanity, closeness and at…

The Hydrothermal System of Solfatara Crater (Campi Flegrei, Italy) Inferred From Machine Learning Algorithms

2019

Two machine learning algorithms were applied to three multivariate datasets acquired at Solfatara volcano. Our aim was to find an unbiased and coherent synthesis among the large amount of data acquired within the crater and along two orthogonal vertical NNE- and WNW-trending cross-sections. The first algorithm includes a new approach for a soft K-means clustering based on the use of the silhouette index to control the color palette of the clusters. The second algorithm which uses the self-organizing maps incorporates an alternative method for choosing the number of nodes of the neural network which aims to avoid the need for downstream clustering of the results of the classification. Both m…

Marte Meo as a port of entry to parental sensitivity - a three–case study

2019

Abstract Background Early parent- child relations play an important role in children’s development. Therapeutic intervention towards infants and toddlers at high-risk intends to prevent mental health problems. In this work, the parent-child-dyad is crucial. The video interaction guidance method, Marte Meo, is one among different methods used in attachment-based treatment in an outpatient infant mental health clinic. Parental sensitivity towards infants and toddlers needs is considered significant in developing secure attachment. Secure attachment is further considered decisive for mental health and the extent to which children are at risk of developing mental health problems. Different trea…

Common Sense and phantasia in Antiquity

2013

Questions concerning the scope, content, and richness of perceptual cognition were widely debated in the ancient philosophical schools. More specific problems related to this theme arose from recognition of the obvious fact that the senses alone are insufficient for explaining the variety of human and animal cognition. Whether or not all such cognition should be ascribed to reason was a matter of debate. Most importantly, opinions diverged with respect to the following questions. Do we have perceptual reflexive cognition, that is, do we perceive that we perceive, or is reflexivity an essentially rational capacity? How can the unity of perceptual cognition be explained in light of the fact t…
