DICE:An open-source MATLAB application for quantification and parametrization of digital outcrop model-based fracture datasets

Journal of Rock Mechanics and Geotechnical Engineering 2023年第5期15卷 1090-1110页

Via Fratelli Cuzio 42Pavia27100Italy

An open-source MATLAB application(app)named Discontinuity Intensity Calculator and Estimator(DICE)was developed in order to quantitatively characterize the fractures,or in more general,discontinuities within a rocky outcrop in three-dimensional(3D)digital data,such as digital outcrop model(DOM).The workflow proposed for the parametrization of the discontinuities consists of the following steps:(1)Analysis and mapping of the fractures detected within the 3D DOMs;(2)Calculation of the orientation,position and dimensions of discontinuities that are represented by best-fit circular planes;(3)Determining the discontinuity parameters(dimension,distribution,spacing and intensity)by the DICE algorithm using different 3D oriented sampling techniques(3D oriented scanline,3D oriented circular scan window and spherical scan volume).Different sampling methods were bench tested with a synthetic,as well as a natural case study,and compared in order to understand the advantages and limitations of each *** 3D oriented circular scan window appears to be the most effective method for fracture intensity estimation with high accuracy(error 0.4%)and stability with variations in scan radius.

α-Synucleinopathies,such as Parkinson’s disease(PD),dementia with Lewy bodies(DLB)and multiple system atrophy,are a class of neurodegenerative diseases exhibiting intracellular inclusions of misfoldedα-synuclein(αSyn),referred to as Lewy bodies or oligodendroglial cytoplasmic inclusions(Papp-Lantos bodies).Even though the specific cellular distribution of aggregatedαSyn differs in PD and DLB patients,both groups show a significant pathological overlap,raising the discussion of whether PD and DLB are the same or different *** clinical investigation,we will focus in addition on methodologies,such as protein seeding assays(real-time quaking-induced conversion),to discriminate between different types ofα-*** approach relies on the seeding conversion properties of misfoldedαSyn,supporting the hypothesis that different conformers of misfoldedαSyn may occur in different types ofα-*** the pathological processes influencing the disease progression and phenotype,provoked by differentαSyn conformers,will be important for a personalized medical treatment in future.
