Evaluation of Statistical Features for Medical Image Retrieval

In this paper we present a complete system allowing the classification of medical images in order to detect possible diseases present in them. The proposed method is developed in two distinct stages: calculation of descriptors and their classification. In the first stage we compute a vector of thirty-three statistical features: seven are related to statistics of the first level order, fifteen to that of second level where thirteen are calculated by means of co-occurrence matrices and two with absolute gradient; the last thirteen finally are calculated using run-length matrices. In the second phase, using the descriptors already calculated, there is the actual image classification. Naive Bayes, RBF, Support VectorMa- chine, K-Nearest Neighbor, Random Forest and Random Tree classifiers are used. The results obtained from the proposed system show that the analysis carried out both on textured and on medical images lead to have a high accuracy

Statistical Features for Image Retrieval: A Quantitative Comparison

In this paper we present a comparison between various statistical descriptors and analyze their goodness in classifying textural images. The chosen statistical descriptors have been proposed by Tamura, Battiato and Haralick. In this work we also test a combination of the three descriptors for texture analysis. The databases used in our study are the well-known Brodatz’s album and DDSM(Heath et al., 1998). The computed features are classified using the Naive Bayes, the RBF, the KNN, the Random Forest and Random Tree models. The results obtained from this study show that we can achieve a high classification accuracy if the descriptors are used all together

The New England Yeoman: noah webster and the defining of american english (1758-1843)

Writing and reflecting on the works of a late eighteenth-century lexicographer today may seem a little unusual and perhaps outdated. Why should linguists and cultural analysts be interested in such a scholar, when so many changes have recently occurred in the English language with the advent of the Internet, digital communication and social media that require our attention? What is the sense nowadays of concentrating our attention on language phenomena and discussions occurred 200 years ago? Shouldn’t we worry about the future development of the English language instead of looking back at its origin? Such rhetorical questions will certainly arouse the offended reaction of most historical linguists. Indeed, the above assertions are of course intended to be a very simple and overt provocative introduction. I am often asked these types of questions in class, and I find that answering to them gives me the opportunity to introduce my favorite topic, i.e. the development of the English language in the United States. And indeed the answer partly lies, at least with regards to the topic of the present article, in the fascinating analysis of the so-called “war of words,” that harsh debate which occurred after the Declaration of American Independence in some British journals and magazines, such as The Critical Review, the European Magazine and London Review, the Gentleman’s Review and the Scots Magazine, to name just a few. There, book reviews, general articles, and letters to the editors attacked shamelessly all attempts on the American intellectuals’ part to claim their acquisition and acknowledgement of an independent and republican culture, not to mention their aim at proclaiming their national sentiment of unity and freedom

The Underground Pride: A Road Map to the Grammar of Freedom

Our proposal aims to illustrate how two apparently different novels – with regards to their historical time of publication, content and scope – can instead show similarities in the rendition of their female protagonists, their treatment of women’s condition, rebellion against social constraints and human bondage. The two novels in question, Jane Austen’s Pride and Prejudice (1813) and Colson Whitehead’s The Underground Railroad (2016), present similarities and obvious differences. They will be analysed from the angle of two intertextual exemplifications and through the analytical framework of Simpson’s point of view in narrative texts. The two intertextual exemplifications we aim to use for our analysis are social conventions and the exit/return dichotomy. With regards to the former intertext, social conventions, we refer to those constraints the two protagonists, Elisabeth and Cora, try to rebel against. The 19th-century Elisabeth Bennet is constantly portrayed as questioning the pressures society imposes upon a young intelligent woman with an uncommon independence of mind. The 19th-century slave girl Cora is in constant search for freedom against all odds. In her journey she nonetheless appeals to her wit to question the violence and predominance of both white men and black men – be them slaves or freemen. The second intertext, exit and return, is drawn somehow from the ‘salidas’ Don Quixote takes to begin each of his trips/viajes (1605) and which lead the way to the pivotal moments in both our novels. Elisabeth’s leaving her home on foot to check on her sister’s health at Longbourn is one example, Cora’s many attempts to flee the plantation is another. As mentioned, both intertexts will be analysed within the framework of Paul Simpson’s illustration of point of view in English narratives (1993). Point of view will be studied in particular with reference to the characters’ perspectives in moments of doubts, when and how society is viewed, judged and questioned. We will refer to Simpson’s narratorial and reflector mode in the third person, depending on “whether the narrative is related from a position outside the consciousness of any character, or whether it is mediated through the consciousness of a particular character” (Simpson: 1993, p. 62). Where the narrator is only apparently taking an objective stance, and where deontic and epistemic modality take turns between what is socially right and what is personally desirable. The analysis of the two intertexts through the lenses of Simpson’s grammar of point of view will hopefully help to clarify our intent to show the reaction of two women against the social imposition of two contemporary and only apparently distant worlds.

Correction: Teeuwssen and fodde; colon cancer heterogeneity and phenotypic plasticity in metastasis formation (Cancers (2019) 11, 9, 1368)

The authors would like to make a correction to their published paper [1]. The authors would like to change one incorrect sentence in reference [1]. On page 9, in paragraph 2, the sentence "In colon cancer, CAFs release exosomes containing miR-92a-3p and promote invasion and chemotherapy resistance. miR-92a-3p directly binds to FBXW7 and MOAP1 thereby activating Wnt-induced EMT and mitochondrial apoptosis [89]'should be changed to "In colon cancer, CAFs release exosomes containing miR-92a-3p and promote invasion and chemotherapy resistance. miR-92a-3p directly binds to FBXW7 and MOAP1 thereby activating Wnt-induced EMT and inhibiting mitochondrial apoptosis [89]." The change does not affect the scientific results. The rest of the manuscript does not to be changed. The authors would like to apologize for any inconvenience caused. The manuscript will be updated, and the original will remain available on the article webpage
