Letter counting: a stem cell for Cryptology, Quantitative Linguistics, and Statistics

Counting letters in written texts is a very ancient practice. It has accompanied the development of Cryptology, Quantitative Linguistics, and Statistics. In Cryptology, counting frequencies of the different characters in an encrypted message is the basis of the so called frequency analysis method. In Quantitative Linguistics, the proportion of vowels to consonants in different languages was studied long before authorship attribution. In Statistics, the alternation vowel-consonants was the only example that Markov ever gave of his theory of chained events. A short history of letter counting is presented. The three domains, Cryptology, Quantitative Linguistics, and Statistics, are then examined, focusing on the interactions with the other two fields through letter counting. As a conclusion, the eclectism of past centuries scholars, their background in humanities, and their familiarity with cryptograms, are identified as contributing factors to the mutual enrichment process which is described here

Eros and Pilgrimage in Chaucer’s and Shakespeare’s Poetry

The paper discusses erotic desire and the motif of going on pilgrimage in the opening of Geoffrey Chaucer’s General Prologue to The Canterbury Tales and in William Shakespeare’s sonnets. What connects most of the texts chosen for consideration in the paper is their diptych-like composition, corresponding to the dual theme of eros and pilgrimage. At the outset, I read the first eighteen lines of Chaucer’s Prologue and demonstrate how the passage attempts to balance and reconcile the eroticism underlying the description of nature at springtime with Christian devotion and the spirit of compunction. I support the view that the passage is the first wing of a diptych-like construction opening the General Prologue. The second part of the paper focuses on the motif of pilgrimage, particularly erotic pilgrimage, in Shakespeare’s sonnets. I observe that most of the sonnets that exploit the conceit of travel to the beloved form lyrical diptychs. Shakespeare reverses the medieval hierarchy of pilgrimage and desire espoused by Chaucer. Both poets explore and use to their own ends the tensions inherent in the juxtaposition of sacred and profane love. Their compositions encode deeper emotional patterns of desire: Chaucer’s narrator channels sexual drives into the route of communal national penance, whereas the Shakespearean persona employs religious sentiments in the service of private erotic infatuations

Cryptography: Mathematical Advancements on Cyber Security

The origin of cryptography, the study of encoding and decoding messages, dates back to ancient times around 1900 BC. The ancient Egyptians enlisted the use of basic encryption techniques to conceal personal information. Eventually, the realm of cryptography grew to include the concealment of more important information, and cryptography quickly became the backbone of cyber security. Many companies today use encryption to protect online data, and the government even uses encryption to conceal confidential information. Mathematics played a huge role in advancing the methods of cryptography. By looking at the math behind the most basic methods to the newest methods of cryptography, one can learn how cryptography has advanced and will continue to advance

Lymphohaematopoietic malignancies in Scottish military veterans: Retrospective cohort study of 57,000 veterans and 173,000 non-veterans

Background: Lymphohaematopoietic malignancies are common in the general population. There have been concerns that military service may be associated with increased risk as a result of occupational exposures. To date, few studies have demonstrated an increased risk, although a disability pension is payable to veterans who were present at nuclear tests and who develop leukaemia (other than chronic lymphocytic leukaemia). The aim of the study was to utilise data from the Scottish Veterans Health Study to examine the risk of lymphohaematopoietic malignancy following military service in a large national cohort of veterans. Methods: Retrospective cohort study of 57,000 veterans and 173,000 non-veterans born between 1945 and 1985 matched for age, sex and area of residence, adjusted for areal deprivation and followed up for up to 30 years, using Cox proportional hazard models to compare the risk of lymphohaematopoietic malignancy overall, by diagnosis and by sex and birth cohort. Results: We found no statistically significant difference in risk between veterans and non-veterans either for all leukaemias (Cox proportional hazard ratio 1.03, 95% confidence intervals 0.84–1.27, p = 0.773), Hodgkin lymphoma (hazard ratio 1.19, 95% confidence intervals 0.87–1.61, p = 0.272) or for non-Hodgkin lymphoma (hazard ratio 0.86, 95% confidence intervals 0.71–1.04, p = 0.110). Conclusion: Our findings provide reassurance that service in the UK Armed Forces is not associated with increased risk of lymphohaematopoietic malignancy

Arabic, Rumi, Coptic, or merely Greek Alphanumerical Notation? The case of a Mozarabic 10th Century Andalusi Manuscript

The aim of this paper is to analyse the notation that appears alongside the Roman numerals in the Latin manuscript MDU-604 of the Capitular Library in Urgell..
