“…Even though the Confusion Matrix is a well-known tool for analyzing classification performance, a two-fold reason is given to introduce basic details about its usage. Firstly, usually the nomenclature of these metrics may vary, e.g., [57][58][59], etc. Secondly, usually only the Overall Accuracy is reported, but [60] demonstrated that this may lead to a quality gap on the information provided that can mislead the user [61,62].…”

An Exploratory Data Analysis (EDA) aims to use Synthetic Aperture Radar (SAR) measurements for discriminating between two oil slick types observed on the sea surface: naturally-occurring oil seeps versus human-related oil spills-the use of satellite sensors for this task is poorly documented in scientific literature. A long-term RADARSAT dataset (2008)(2009)(2010)(2011)(2012)) is exploited to investigate oil slicks in Campeche Bay (Gulf of Mexico). Simple Classification Algorithms to distinguish the oil slick type are designed based on standard multivariate data analysis techniques. Various attributes of geometry, shape, and dimension that describe the oil slick Size Information are combined with SAR-derived backscatter coefficients-sigma-(σ o ), beta-(β o ), and gamma-(γ o ) naught. The combination of several of these characteristics is capable of distinguishing the oil slick type with~70% of overall accuracy, however, the sole and simple use of two specific oil slick's Size Information (i.e., area and perimeter) is equally capable of distinguishing seeps from spills. The data mining exercise of our EDA promotes a novel idea bridging petroleum pollution and remote sensing research, thus paving the way to further investigate the satellite synoptic view to express geophysical differences between seeped and spilled oil observed on the sea surface for systematic use.

“…8 Both studies used the Mini-Mental State Examination as a global measure of cognitive function. 9 There is, however, longstanding consensus that a battery of neuropsychological tests is required to detect POCD reliably after cardiac surgery. 10 Furthermore, it is currently unclear how postoperative cognitive function evolves over time with respect to the magnitude of the change, changes in overall cognitive function, and changes in different cognitive domains.…”

“…[77][78][79][80][81][82] In an international, multicentre cohort study of 4,707 patients undergoing coronary artery bypass surgery, a one point increase in NIHSS score predicted fatal and non-fatal stroke, transient ischaemic attack and coma at hospital discharge with a specificity of 86% and sensitivity of 84%. 27 The diagnostic performance was substantially improved when a 2-point increase in NIHSS was considered (specificity of 94%). 27 NIHSS is however, insensitive to strokes in the posterior circulation.…”

Perioperative stroke is a devastating complication that carries high mortality and functional disability. Unfortunately, residual anaesthesia and analgesia may obscure important warning signs and may lead to a delay in the assessment and treatment of major stroke after surgery. The purpose of this review is to examine the utility of existing stroke scales, for the recognition of perioperative stroke in the general surgical population. A total of 21 stroke scales have been described in the literature. Diagnostic performance was reported in 17 scales. The majority of the stroke scales were designed to evaluate current neurological deficits after an established stroke event. Recent abbreviated stroke test, such as the Face, Arm, Speech Test (FAST), were developed to facilitate stroke identification in the emergency department. Only two stroke scales have been applied in the perioperative setting after cardiac, carotid and neurological surgeries. The modified National Institutes of Health Stroke Scale appears to be useful in detecting new subtle neurological deficits in critical care, or high dependency units after surgery. However, in the general postsurgical wards, given the concern about the workload required, abbreviated stroke tests may be more appropriate for routine regular stroke surveillance. It is hoped that these tests will provide rapid assessment of global neurological function to facilitate timely diagnosis and treatment of perioperative stroke.
