The present article explores the collective imaginary of the cenacle, referring to the case of Viața românească literary group from Iași, focussing on the bodily community and its representations in the common space, understood as space-in-common. This approach shifts the interest from the ideological component that is the ‘poporanism’, as promoted by Viața românească revue, to the ethical and social aspects of the community. This does not mean that the bodily community is “more real” than the ideological community, or that it translates with fidelity the common practices of the cenacle; the bodily community is in fact another form of representation, a phantasm of the living-together, analysed through Roland Barthes’s theory as the space where solitude and sociability coexist. The corporal representations of the community, always engaged in an ethical debate, is further discussed through two manners of the living-together: the gesture and the rhythm. The theoretical reference of this analysis is Marielle Macéʼs book Styles. Critique de nos formes de vie, which proposes a formal approach of life, concentrating on the ethical implications. The issues derived from this sort of reading state the relation between the body and the environment, the vicinities and the somatic interactions between the members of the cenacle, the adjustment of distances, and the maintenance of solitude inside the community. The gestures, attitudes, behaviour, verbal and non-verbal tics, clothing, the manners of speech or the rhythm of doing certain things are seen not as marks of personal identity that positions itself inside the spaces of power, but as collective signs, as form of encounter and interaction, of exposure to the others but also responsiveness of the others, of expropriation as well as appropriation, of affirmation as well as alteration of the forms of life.

Electroencephalography (EEG) is the measurement of neuronal activity in different areas of the brain through the use of electrodes. As EEG signal technology has matured over the years, it has been applied in various methods to EEG emotion recognition, most significantly including the use of convolutional neural network (CNN). However, these methods are still not ideal, and shortcomings have been found in the results of some models of EEG feature extraction and classification. In this study, two CNN models were selected for the extraction and classification of preprocessed data, namely, common spatial patterns- (CSP-) CNN and wavelet transform- (WT-) CNN. Using the CSP-CNN, we first used the common space model to reduce dimensionality and then applied the CNN directly to extract and classify the features of the EEG; while, with the WT-CNN model, we used the wavelet transform to extract EEG features, thereafter applying the CNN for classification. The EEG classification results of these two classification models were subsequently analyzed and compared, with the average classification accuracy of the CSP-CNN model found to be 80.56%, and the average classification accuracy of the WT-CNN model measured to 86.90%. Thus, the findings of this study show that the average classification accuracy of the WT-CNN model was 6.34% higher than that of the CSP-CNN.

This study concerns the struggle for Philadelphia's LOVE Park, which involved the general public and its functionaries on one side and skateboarders on the other. This paper argues LOVE Park was one place composed of two distinct spaces: the public space the public engendered and the common space the skateboarders produced. This case demonstrates that public and common space must be understood as distinct, for they entail different understandings of publicly accessible space. Additionally, public and common spaces often exist simultaneously as “public–common spaces,” which emphasizes how they reciprocally shape one another. This sheds light on the emergence of “anti–common public space,” which is evident in LOVE Park's 2016 redesign. This concept considers how common spaces are increasingly negated in public spaces. The introduction of common space to the study of public spaces is significant as it allows for more nuanced understandings of transformations in the urban landscape.

DL-Allylglycine (DL-2-amino-4-pentenoic acid, C5H9NO2) yields crystals with Pca21 symmetry and two crystallographically independent yet pseudo-inversion-related enantiomers. The distribution among the common space groups of other crystalline racemates with more than one molecule in the asymmetric unit has been established. The conformational similarities between crystallographically independent enantiomers in 114 non-centrosymmetric racemates were quantified using the r.m.s. deviation for a molecular superposition. The analysis shows that in the majority of crystals the conformations of the crystallographically independent molecules are very similar with mean r.m.s. deviation = 0.190 Å. In almost 80% of the structures the mean r.m.s. deviations is in the interval 0–0.2 Å. It is estimated that racemates constitute 23% of the centrosymmetric organic structures in the Cambridge Structural Database.

The article discus ses some semiotic approaches to the relation between nature and culture. Starting with outlining the structuralistic approach to this issue, especially the ideas of Juri Lotman and Algirdas Julien Greimas, the author finds parallels between different views on the relation between the natural world and human beings. First, the juxtaposition of Eero Tarasti’s existential semiotics with selected concepts of biosemiotics is discussed. The following part of the paper is dedicated to Bruno Latour’s ideas on nature–culture relation, hybrids and mediations. Then the author refers to Lotman’s notion of the semiosphere as the common space for all living and inanimate elements. Closing the paper with a return to biosemiotics, the author comes back to Tarasti’s ideas and compares these with some ideas in biosemiotics, paying special attention to the concepts of unpredictability, choice and dynamics. The comparison shows that some intuitions, assumptions and theses of these different scholars turn out to be surprisingly convergent. The author believes that the outlined parallels between Tarasti’s view, Latour’s and Lotman’s concepts, and biosemiotics may be promising for further research, inviting detailed study.
