One approach to assessing overall opinion polarity (OvOP) of reviews, a concept defined in this paper, is the use of supervised machine learning mechanisms. In this paper, the impact of lexical filtering, applied to reviews, on the accuracy of two statistical classifiers (Naive Bayes and Markov Model) with respect to OvOP identification is observed. Two kinds of lexical filters, one based on hyper

Teatern och skådespelaren har i olika sammanhang och under olika historiska epoker betraktats med misstroende och fientlighet. Man kan rent av tala om en historisk tradition av antipatier där teaterscenen och skådespelarens förvandlingskonst har misstänkliggjorts i egenskap av moraliska instanser. I denna tradition möts filosofer och religiösa moralister, men också teaterpraktiker med olika agendo

Background: Dermatitis caused by occupational contact allergy to rubber additives such as diphenylguanidine (DPG) in medical gloves is a hazard for healthcare workers. Both the duration of exposure to medical gloves and the number of gloves used per day vary. The use of alcoholic skin disinfectants before glove donning is mandatory. Objectives: To assess whether skin exposure to the rubber acceler

I Egypten har Islamiska statens (IS) uppdykande lett till en nödvändig religionsdebatt som spritt sig till sociala nätverk världen över. Motsvarande debatt ser vi inte bland muslimska företrädare här hemma.

Background: The outlook for patients with esophageal and gastric (EG) cancer remains poor. Hence, there is a compelling need to identify novel treatment strategies and complementary biomarkers. Programmed death ligand 1 (PD-L1) and mismatch repair deficiency (dMMR) are putative biomarkers of response to immune-checkpoint blockade, but their prognostic value and interrelationship in EG cancer have

120 kristna mördades, 128 kidnappades, det genomförde 146 attacker mot kyrkor och 700 kristna familjer tvingades fly sina hem under 2013. Detta var priset för att Muslimska Brödraskapet utövade makten i Egypten under ett år. Ett högt pris för kristna i Egypten men kan inte jämföras med andra länder i regionen.

Background: The relationship between schizophrenia and acute coronary syndrome (ACS) has already been established. This study aims to investigate the difference in length of in-hospital stay (LoS) between a population with schizophrenia and a psychiatric healthy control (PHC) population following admission for a first ACS. Methods: Data for this retrospective study was collected from three nation

Introduction: Prehospital and hospital emergency care guidelines have been developed for patients with suspected hip fracture. Initial radiography can identify a number of patients with other injuries, generally pelvic fractures and hip contusions. Little is known about the prognosis for these patients. The aim of this study is twofold: i) to investigate the injury pattern of patients assessed in

We introduce the Szegő class, Sz(E), for an arbitrary Parreau–Widom set E ⊂ ℝ and study the dynamics of its elements under the left shift. When the direct Cauchy theorem holds on ℂ\E, we show that to each J ∈ Sz(E) there is a unique element J′ in the isospectral torus, T E , so that the left-shifts of J are asymptotic to the orbit {J′ m } on T E . Moreover, we show that the ratio of the associ

Melanoma of the skin is the sixth most common type of cancer in Europe and accounts for 3.4% of all diagnosed cancers. More alarming is the degree of recurrence that occurs with approximately 20% of patients lethally relapsing following treatment. Malignant melanoma is a highly aggressive skin cancer and metastases rapidly extend to the regional lymph nodes (stage 3) and to distal organs (stage 4)
