Science des donnéesLa science des données est l'étude de l’extraction automatisée de connaissance à partir de grands ensembles de données. Plus précisément, la science des données est un domaine interdisciplinaire qui utilise des méthodes, des processus, des algorithmes et des systèmes scientifiques pour extraire des connaissances et des idées à partir de nombreuses données structurées ou non . Elle est souvent associée aux données massives et à l'analyse des données.
Myélite transverseLa myélite transverse (MT) est un syndrome neurologique traduisant une inflammation de la moelle spinale pouvant toucher l'adulte comme l'enfant. Son étiologie est encore mal comprise, mais semble principalement auto-immune car elle survient souvent après une infection virale (herpès, mycoplasme, EBV, CMV, VIH...) ou un vaccin, ce qui laisse penser qu'il s'agit d'une "mauvaise" réaction de l'organisme qui au lieu de protéger ses cellules se retourne contre certaines d'entre elles.
Congenital vertebral anomalyCongenital vertebral anomalies are a collection of malformations of the spine. Most, around 85%, are not clinically significant, but they can cause compression of the spinal cord by deforming the vertebral canal or causing instability. This condition occurs in the womb. Congenital vertebral anomalies include alterations of the shape and number of vertebrae. Lumbarization is an anomaly in the spine. It is defined by the nonfusion of the first and second segments of the sacrum.
Spinocerebellar tractThe spinocerebellar tract is a nerve tract originating in the spinal cord and terminating in the same side (ipsilateral) of the cerebellum. Proprioceptive information is obtained by Golgi tendon organs and muscle spindles. Golgi tendon organs consist of a fibrous capsule enclosing tendon fascicles and bare nerve endings that respond to tension in the tendon by causing action potentials in type Ib afferents. These fibers are relatively large, myelinated, and quickly conducting.
Data dredgingvignette|Exemple de Data dredging. Le data dredging (littéralement le dragage de données mais mieux traduit comme étant du triturage de données) est une technique statistique qui . Une des formes du data dredging est de partir de données ayant un grand nombre de variables et un grand nombre de résultats, et de choisir les associations qui sont « statistiquement significatives », au sens de la valeur p (on parle aussi de p-hacking).
Olfactory ensheathing cellOlfactory ensheathing cells (OECs), also known as olfactory ensheathing glia or olfactory ensheathing glial cells, are a type of macroglia (radial glia) found in the nervous system. They are also known as olfactory Schwann cells, because they ensheath the non-myelinated axons of olfactory neurons in a similar way to which Schwann cells ensheath non-myelinated peripheral neurons. They also share the property of assisting axonal regeneration. OECs are capable of phagocytosing axonal debris in vivo, and in vitro they phagocytose bacteria.
Douleur neuropathiqueLa douleur neuropathique est une douleur causée par une lésion des voies sensitives (canalopathies des canaux calciques) du système nerveux, central ou périphérique. La douleur neuropathique est généralement associée à une dysesthésie et une allodynie. Il peut exister une zone gâchette déclenchant les douleurs. Les douleurs neuropathiques peuvent être à type de brûlure, de froid, ou de sensations de piqûres, et s'accompagner de sensations de fourmillement.
Testing hypotheses suggested by the dataIn statistics, hypotheses suggested by a given dataset, when tested with the same dataset that suggested them, are likely to be accepted even when they are not true. This is because circular reasoning (double dipping) would be involved: something seems true in the limited data set; therefore we hypothesize that it is true in general; therefore we wrongly test it on the same, limited data set, which seems to confirm that it is true.
Pain management during childbirthPain management during childbirth is the treatment or prevention of pain that a woman may experience during labor and delivery. The amount of pain a woman feels during labor depends partly on the size and position of her baby, the size of her pelvis, her emotions, the strength of the contractions, and her outlook. Tension increases pain during labor. Virtually all women worry about how they will cope with the pain of labor and delivery. Childbirth is different for each woman and predicting the amount of pain experienced during birth and delivery can not be certain.
Exploratory data analysisIn statistics, exploratory data analysis (EDA) is an approach of analyzing data sets to summarize their main characteristics, often using statistical graphics and other data visualization methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling and thereby contrasts traditional hypothesis testing. Exploratory data analysis has been promoted by John Tukey since 1970 to encourage statisticians to explore the data, and possibly formulate hypotheses that could lead to new data collection and experiments.
