    Abstract Global eating habits cause health issues leading people to mindful eating. This has directed attention to applying deep learning to food-related data. The proposed work develops a new framework integrating neural network and natural language processing for classification of food images and automated recipe extraction. It address the challenges of intra-class variability and inter-class similarity in food images that have received shallow attention in the literature. Firstly, a customized lightweight deep convolution neural network model, MResNet-50 for classifying food images is proposed. Secondly, automated ingredient processing and recipe extraction is done using natural language processing algorithms: Word2Vec and Transformers in conjunction. Thirdly, a representational semi-structured domain ontology is built to store the relationship between cuisine, food item, and ingredients. The accuracy of the proposed framework on the Food-101 and UECFOOD256 datasets is increased by 2.4% and 7.5%, respectively, outperforming existing models in literature such as DeepFood, CNN-Food, Wiser, and other pre-trained neural networks.

    Abstract Golden jackal (Canisaureus) expansion in the last decades has triggered research interest in Europe. However, jackal phylogeny and taxonomy are still controversial. Morphometric studies in Europe found differences between Dalmatian and the other European jackals. Recent genetic studies revealed that African and Eurasian golden jackals are distinct species. Moreover, large Canisaureuslupaster may be a cryptic subspecies of the African golden jackal. Although genetic studies suggest changes in Canisaureus taxonomy, morphological and morphometric studies are still needed. The present study proposes the first comprehensive analysis on a wide scale of golden jackal skull morphometry. Extensive morphometric data of jackal skulls from Europe (including a very large Bulgarian sample), Asia Minor, and North Africa were analysed, by applying recently developed statistical tools, to address the following questions: (i) is there geographic variation in skull size and shape among populations from Europe, Anatolia and the Caucasus?, (ii) is the jackal population from the Dalmatian coast different?, and (iii) is there a clear distinction between the Eurasian golden jackal (Canisaureus) and the African wolf (Canislupaster sensu lato), and among populations of African wolves as well? Principal component analysis and linear discriminant analysis were applied on the standardized and log-transformed ratios of the original measurements to clearly separate specimens by shape and size. The results suggest that jackals from Europe, Anatolia and the Caucasus belong to one subspecies: Canisaureusmoreotica (I. Geoffroy Saint-Hilaire, 1835), despite the differences in shape of Dalmatian specimens. The present study confirmed morphometrically that all jackals included so far in the taxon Canisaureus sensu lato may represent three taxa and supports the hypothesis that at least two different taxa (species?) of Canis occur in North Africa, indicating the need for further genetic, morphological, behavioural and ecological research to resolve the taxonomic uncertainty. The results are consistent with recent genetic and morphological studies and give further insights on golden jackal taxonomy. Understanding the species phylogeny and taxonomy is crucial for the conservation and management of the expanding golden jackal population in Europe.

    Abstract The identity of Lithospermum rochelii, so far known only from its type locality (Bulgaria, hills in Plovdiv town), remained hitherto uncertain. Our examination of its original material and re‐collection of the species from its locus classicus in Plovdiv town revealed its identity with Lithospermum glandulosum (syn. Buglossoides glandulosa) described later from an adjacent area, in the towns of Sadovo and Asenovgrad (Plovdiv Region), and Lithospermum czernjajevii (syn. Buglossoides czernjajevii), described from north‐eastern Ukraine in the 20th century. The diagnostic characters of L. rochelii and related taxa are clarified, and the distribution area of this species is verified and mapped. A lectotype is designated for L. rochelii and a new combination is provided, Buglossoides rochelii. The chromosome number 2n = 2x = 16, the first ever record for the species, confirms its sharp separation from all other members of Buglossoides s.str., for which only the base chromosome number x = 7 has been known.

    Abstract Objective: The original user version of the Mobile Application Rating Scale (uMARS) is an English-language questionnaire that was designed to allow non-expert app users to assess the quality of health apps. We aimed to translate into the Greek language and validate the uMARS.
    Methods: This was a qualitative prospective study. The World Health Organization translation process was followed and a readily available and free-of-charge app was used for the validation process. Internal consistency and reliability were tested twice within one month by 91 Greek medical students.
    Results: The total uMARS score showed excellent internal consistency (Cronbach's alpha = 0.86). The internal consistencies of its subscales were also very high (engagement alpha = 0.71; functionality alpha = 0.71; aesthetics alpha = 0.67; information alpha = 0.63), with the notable exception of the satisfaction alpha, which was 0.61. The uMARS total score demonstrated almost perfect agreement levels in most of the subscales according to the r
    Conclusions: The Greek uMARS is a reliable and valid tool for assessing the quality of mobile apps.
