“…Chaotic mappings are typically used to generate pseudo-random sequences, which serve as keys for image encryption. For instance, Stolova et al (2015) [19] proposed an image encryption algorithm based on singular chaotic mappings. They used logistic chaos mapping to generate a pseudo-random sequence and performed a heteroskedastic operation with the original image to achieve encryption.…”

With the rapid development of information technology, the security of images has emerged as a significant area of research. This study presents an algorithm that integrates chaotic image encryption and a convolutional neural network (CNN) to enhance security and efficiency. The algorithm applies the properties of randomness and nonlinear mapping of chaotic sequences with the advanced feature extraction capabilities of a CNN model to achieve robust image encryption. First, we outline the fundamentals of chaotic image encryption and CNN. Chaotic image encryption employs chaotic sequence generation and nonlinear mapping to scramble pixel values for encryption purposes, while a CNN, as a deep-learning model with a local perceptual field and weight sharing, effectively extracts high-level image features. Subsequently, we provide a detailed description of the specific steps involved in combining chaotic image encryption and the CNN. These steps include chaotic sequence generation, pixel value mapping, feature extraction, and key management. The algorithm achieves high-strength encryption by performing dissimilarity operations between the chaotic sequence and image pixel values, as well as extracting high-level image features using the CNN. Finally, we conduct experimental evaluations of the algorithm and compare it with traditional chaotic image encryption methods. The experimental results demonstrate that the image encryption algorithm exhibits significant improvements in encryption quality and security while offering advantages in computational performance and encryption/decryption speed.

De lever la main à lever l’interdit : Les verbes transitifs de déplacement vertical et leurs extensions sémantiques

L’article traite de plusieurs glissements de sens (semantic shifts) formant une chaîne d’acceptions qui, d’après ses deux maillons extrêmes, peut être appelée to take up → to abolish. Ces glissements de sens seront illustrés par des exemples tirés de 11 langues indoeuropéennes, relevant de différents groupes (helléniques, germaniques et romanes). L’enjeu de l’étude consiste à révéler les bases cognitives du développement sémantique des verbes désignant initialement l’action to take up, qui constitue un modèle apparemment commun à plusieurs langues. La structure de la chaîne en question reflète un accroissement progressif de la distance entre l’objet déplacé et son emplacement initial, ce qui conduit naturellement aux sens to take off, puis to take away. Les maillons finaux de la chaîne représentent la réalisation ultime de l’idée du déplacement de l’objet qui se manifeste dans les acceptions to destroy et to abolish. Ce schéma du développement sémantique des verbes dont le sens primaire est to take up peut être repéré dans de nombreuses langues du monde sous forme de parallèles sémantiques (y compris parmi plusieurs lexèmes au sein d’une même langue). Les occurrences de polysémie régulière témoignent de la pertinence de ce changement sémantique en tant qu’outil de l’appréhension de la réalité et de la réflexion de ses phénomènes dans le langage naturel, aussi bien que de l’implication de mécanismes cognitifs fondamentaux dans l’évolution sémantique de ces verbes.

“…From a semantic standpoint, climb is classified as a manner-of-motion verb, and it is sometimes referred to as a neutral or ordinary verb, such as walk and fly, as opposed to more expressive verbs like dash, swoop, or scramble (Cadierno -Ruiz 2006). 6 Climb implies self-propelled, agentive, voluntary, self-caused, or internally caused motion and can be augmented by a number of locative adverbs and prepositions that give the verb a directional component (Filipović 2007;Goddard 2020;Kudrnáčová 2013;Stolova 2011). Berman and Slobin (1994) discovered that three-to four-year-old English-speaking toddlers connected climb with down, on, out, over, up, up in, and up on in Mayer's (1969) Frog, where are you?…”

Encoding climbing scenes in English : frequency and patterns in descriptions written by speakers of diverse languages

The English verb climb has a greater range of syntactic formulations than its Ladin and Italian counterparts, the majority of which do not take direct objects and most commonly express effortful uphill movement; however, German appears typologically closer to English. As a result, the question arises as to whether English learners with diverse first languages make different lexical and syntactic choices when describing climbing scenes in the target language. Because of diverse cross-linguistic impacts, it is expected that German speakers will employ the English verb climb in more contexts than Ladin and Italian speakers. Trentino-South Tyrolean speakers of Ladin (n = 13), Italian (n = 40), and German (n = 40) describe 12 artworks depicting a figure rising in various surroundings and directions, to confirm this fact. The preceding finding is corroborated by an online video-description task completed by speakers of Ladin (n = 57), Italian (n = 45), and German (n = 45). Despite difficulties distinguishing across multilingual groups of learners, this study reveals disparities amongst student groups with similar multilingual backgrounds. Contrastive assessment of multilingual learners' descriptions of human climbing scenarios indicates tendencies that are likely attributable to cross-linguistic variance.
