The goal of an email service provider company is to send out a large number of emails to help its clients realise successful email marketing activities. Thousands of emails sent every minute need to be analysed in real time to reduce spam or phishing. The paper describes a method that uses real-time tracking of key campaign metrics such as the opens count, clicks count, hard bounces count, etc., to identify campaigns that should be stopped because they can be classified as spam or phishing. The key point of this solution is that we do not analyse email content. Nevertheless, the proposed neural networks are highly effective—the F1-score is above 0.95 for any used sample. Furthermore, the approach allows us to use the same model regardless of the language of an email. The method was developed and verified in collaboration with Freshmail, a leading provider of email marketing services in Poland. Validation of the method on real data provided by the company confirmed its high effectiveness. [ABSTRACT FROM AUTHOR]

The aim of this article is to trace the means of presenting the Battle of Varna in the Polish historiographic sources until the end of the 16th century. Particular attention was given to such narrative elements as: issue of oath-breaking by the Christian side, information on Poles participating in the battle, formation of king Władysław's remembrance or establishment of the Jagiellonian Dynasty as the defender of Christendom (which was associated with the conviction of Poland's unique role in Europe as the Bulwark of Christendom). The article also indicates functions which the recollection of the memory of the Battle of Varna could have played throughout the period of more than a hundred years, particularly in the context of cultural memory.

The article analyzes the economic content that appeared in the narratives of Władysław I the Elbow-high's documents. References to the economic sphere occurring there were divided into two types. The first one contained information on the economic condition of an area, first and foremost about the destruction or war devastation that hit a given region or town. The second type justified ruler's decisions, a desire to reform or to increase the benefits of the monarchy and his subjects. On the basis of the data obtained, an attempt was made to comment on the economic awareness of the ruler. [ABSTRACT FROM AUTHOR]

Epidemiological studies on myelodysplastic syndromes (MDS) in Middle-Eastern Europe are scarce. No data about the demographic, clinical, and laboratory features of Polish MDS patients have been published. The aim of this study was to assess the epidemiological data and toxic exposure of Polish MDS patients and their association with hematological parameters and clinical outcomes. For 15 months, 966 living MDS patients were enrolled at 24 centers (12 university and 12 community hospitals). Follow-up was conducted for the next 55 months. The percentage of patients older than 80 years (16%) was between the values for Eastern and Western countries. In patients younger than 55 years, a female predominance was observed (male/female ratio 0.70:1 vs. 1.29:1; p < 0.001). Female patients had higher platelet counts (160 × 109/l vs. 111 × 109/l; p < 0.001). Patients exposed to chemicals were younger than patients without such exposure; their median age at MDS diagnosis was 66 vs. 70 years (p = 0.037). Smokers had significantly lower hemoglobin concentrations (8.6 vs. 9.1 g/dl; p = 0.032) and lower platelet counts (99 × 109/l vs. 137 × 109/l; p < 0.001) than nonsmokers. We provide the first description of the characteristics of Polish MDS patients. Females predominated in the group aged <60 years and they had higher platelet counts. The course of the disease is affected by toxic exposure and smoking. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

The aim of the study was to reveal the relationships between the tuber count of the brain found in patients with tuberous sclerosis complex (TSC) and their cognitive outcome. A single-center, retrospective analysis was performed of patients with documented TSC seen from 1988 to 2010 at the Children's Memorial Health Institute, Warsaw, Poland. Sixty-two patients were analyzed, and there was a significant correlation between younger age at the first seizure and developmental delay. The patients who did not develop seizures had normal development, despite some presenting with higher tuber load than those with seizures. There was a statistically significant negative correlation between the number of tubers within the right temporal lobe and cognition. Our findings confirm our hypothesis that the cognitive outcome in TSC is more dependent on the age of the seizure onset rather than on the tuber count. [ABSTRACT FROM AUTHOR]
