title: PAPPADIA THEOREM - A UNIVERSAL METHOD FOR CALCULATING DECIMAL PERIODS OF FRACTIONS

description: We present the Pappadia Theorem for the direct calculation of the period and antiperiod of rational fractions in their decimal representation. The theorem establishes that for a fraction p/q in reduced form with q = 2^a · 5^b · M where gcd(M, 10) = 1, the antiperiod length is μ = max(a, b) and the period length is λ = ord_M(10), where ord_M(10) denotes the multiplicative order of 10 modulo M. The algorithmic implementation achieves computational complexity O(log M) versus the traditional complexity O(λ), obtaining performance improvements of 10-100× for fractions with long periods.

The repository contains the reference Python implementation of the theorem, with complete validation across different categories of fractions. While this document presents the fundamental algorithm, commercial implementations with additional optimizations (Pappadia Booster) are available under commercial license.

title: Replication Data for: Only In It for Power and Wealth? The Neglect of Policy-Seeking Motives among Dictators

description: Contrary to the dominant literature on autocracies, this article argues and shows that dictators, in addition to being office-seeking, are often driven by policy-seeking motivation, that is, broader beliefs and ideology. The empirical investigation enlists new original data, based on obituaries, on dictators’ political motives. The dataset contains information on 297 deceased dictators who held power at some point during the period 1945-2008. The results reveal that the dictators had a variety of different motives for being in power. Many were strongly ideologically motivated, several were primarily motivated by money and power ambitions, and yet others held power to create stability and democratize. Thus, dictators’ motives seem to be substantially more diverse than normally assumed, and the data make it possible to measure motivation, which is key to investigating the direct as well as the conditional impact on political dynamics in autocracies.

title: Shallow firn cores on Thwaites Eastern Ice Shelf - densities and water isotope analysis

description: This dataset contains measurements of firn densities and d18O, dD, and d-excess of O2 from water samples taken from two shallow firn cores on Thwaites Eastern Ice Shelf. The shallow firn cores were collected at Cavity Camp and Channel Camp on January 5 and 8, 2023 (respectively). The core was sampled at 3-10cm resolution, down to 8m below the surface (covering approximately the period of 2018-2023). Water samples were collected from each section of the core, melted, and used for water isotope analysis, which was performed in June 2023. The data file contains three sheets: a README, the data from Channel Camp, and the data from Cavity Camp.

title: SH1421235.10FU

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
