Once susceptibility to β-lactam and fluoroquinolone antibiotics has been lost, other therapeutic options such as aminoglycoside or polymyxin antibiotics carry significant adverse effects such as nephrotoxicity, neurotoxicity, and ototoxicity. A novel cephalosporin, cefiderocol, lacks gram-positive and anaerobic activity but offers broad coverage of gram-negative bacteria, including P. aeruginosa. A unique catechol side chain gives it activity as a siderophore, thereby increasing bacterial uptake and decreasing efflux. Additionally, cefiderocol is stable against a wide array of β-lactamases. Despite these promising characteristics, there are minimal data currently available in the literature detailing the use of cefiderocol in the treatment of MDR P. aeruginosa infections. We present a case of a 46-year-old man who developed an MDR P. aeruginosa intraabdominal infection where serious and life-threatening toxicities to aminoglycosides and polymyxin antibiotics led to the utilization of cefiderocol on compassionate use approval. The isolate was susceptible to cefiderocol, and the patient was treated for 28 days of therapy. He demonstrated clinical and radiographic resolution of his infection and was discharged to home.</p>","PeriodicalId":42909,"journal":{"name":"Foundations of Computing and Decision Sciences","volume":"47 1","pages":"1113-1118"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/phar.2334","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83173061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, pooling provides the ability to learn invariant features and also acts as a regularizer to further reduce the problem of overfitting. Additionally, the pooling techniques significantly reduce the computational cost and training time of networks which are equally important to consider. Here, the performances of pooling strategies on different datasets are analyzed and discussed qualitatively. This study presents a detailed review of the conventional and the latest strategies which would help in appraising the readers with the upsides and downsides of each strategy. Also, we have identified four fundamental factors namely network architecture, activation function, overlapping and regularization approaches which immensely affect the performance of pooling operations. It is believed that this work would help in extending the scope of understanding the significance of CNN along with pooling regimes for solving computer vision problems.","PeriodicalId":42909,"journal":{"name":"Foundations of Computing and Decision Sciences","volume":"44 1","pages":"303 - 330"},"PeriodicalIF":1.1,"publicationDate":"2019-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47797572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The new techniques were introduced in an extensible. NET application that serves as both an executable program and a library.

Many issues related to this task such as handling of negation or of sarcastic utterances were analyzed and accordingly addressed in previous works. However, the issue of class imbalance which often compromises the prediction capabilities of learning algorithms was scarcely studied. In this work, we aim to bridge the gap between imbalanced learning and sentiment analysis. An experimental study including twelve imbalanced learning preprocessing methods, four feature representations, and a dozen of datasets, is carried out in order to analyze the usefulness of imbalanced learning methods for sentiment classification. Moreover, the data difficulty factors — commonly studied in imbalanced learning — are investigated on sentiment corpora to evaluate the impact of class imbalance.","PeriodicalId":42909,"journal":{"name":"Foundations of Computing and Decision Sciences","volume":"44 1","pages":"151 - 178"},"PeriodicalIF":1.1,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2478/fcds-2019-0009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45572326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
