Among many other themes, Leonardo da Vinci’s Manuscript B contains several drawings of centrally planned churches, some of which are represented using a plan view paired with a bird’s-eye view. The use of a bird’s-eye instead of an elevation represents an innovative depiction technique, which allows to combine the immediacy of the perspective view with the measurability of the façades, and therefore to describe the three-dimensionality of the buildings. To understand the reasons behind the use of this original technique, the edifices’ shape and classify them we decided to use 3D digital reconstruction techniques, for their ability to avoid misunderstandings in the reconstruction process and in the results. This article describes the method to create the digital models of sixteen churches. A Visual programming language (VPL) script was used as 3D base for modelling the churches achieved from a classification code expressing the aggregative rules of the churches. Then, the geometric process for the construction of the plan and its relationship with the elevation measures was studied for each church. Finally, this information was used for the completion of the 3D models, distinguishing more output variants each time there was an inconsistency between plan and perspective view, a variability of one architectural element or an uncertainty.

Hidden markov models are a very useful tool in the modelling of time series and any sequence of data. In particular, they have been successfully applied to the field of mathematical linguistics. In this paper, we apply a hidden markov model to analyze the underlying structure of an ancient and complex manuscript, known as Voynich's manuscript, that remains still undeciphered. By assuming a certain number of internal states representations for the symbols of the manuscript we train the network by means of the $\alpha$ and $\beta$-pass algorithms to optimize the model. By this procedure, we are able to obtain the so-called transition and observation matrices in order to compare with known languages concerning the frequency of consonant and vowel sounds. From this analysis, we conclude that transitions occur between the two states with similar frequencies to other languages. Moreover, the identification of the vowel and consonant sounds matches some previous tentative bottom-up approaches to decode the manuscript.

Objective: The Asia-Pacific region (APAC) represents a unique environment for the publication of biomedical research, particularly industry-funded research. Awareness and adoption of international guidelines on ethical publication practices continues to increase across APAC, but the reframing and expansion of many of the recommendations in the Good Publication Practice (GPP) 2022 guidelines versus GPP3 published in 2015 have important implications for publishing industry-funded biomedical research in the region. Methods: This manuscript provides practical guidance for stakeholders in APAC on interpreting and applying the recommendations made in the GPP 2022 guidelines. Results: Key focus areas include navigating new opportunities for communicating industry-funded research, such as plain language summaries, social media, and preprints; implementing formal processes to improve the integrity of published research in APAC; and methods of promoting transparency and inclusion when publishing industry-funded research. Key APAC-specific issues, including encore presentations, leadership on publication ethics in the region, access to professional resources, and support for educating regional stakeholders are also discussed. Conclusions: Overall, this review offers a pragmatic guide for stakeholders in industry-sponsored research on applying GPP 2022 in practice with a focus on effectively integrating these guidelines in an APAC context.

This paper provides the solution to understanding the hitherto unknown writing system used for the manuscript listed as MS 408 at the Beinecke Library, Yale University. The writing system uses symbols, punctuation, grammar and language that are each unique. The manuscript is not encrypted, in the sense that its author made an effort to conceal the contents of the manuscript, as has been presumed by some scholars. Instead, it is code only in the sense that the modern reader needs to be versed in the calligraphic and linguistic rules to be able to translate and read the texts. Furthermore, in discovering its writing system, it became apparent that the manuscript is of invaluable importance to the study of the evolution of the Romance languages and the scheme of Italic letters and associated punctuation marks now commonplace in those and other modern languages. In short; it is revealed to be the only known document both written in Vulgar Latin, or proto-Romance, and using proto-Italic symbols. The original title for the manuscript, given by its female author, is: What one needs to be sure to acquire for the evils set in one’s fate. It is a book offering homeopathic advice and instruction to women of court on matters of the heart, of sexual congress, of reproduction, of motherhood and of the physical and emotional complications that can arise along the way through life. The manuscript has now been dated to the year 1444 and the location of its creation has been pinpointed to the court of Castello Aragonese, on the island of Ischia: as expounded in the companion paper Linguistically Dating and Locating Manuscript MS408: http://ling.auf.net/lingbuzz/003808.
