Can reenactment both as reactivation of images and restaging of exhibitions be considered an alternative way of tackling the critical task to re-present art history (i.e., to present it anew) in the here and now, over and over and over again? The gesture of restoring visibility to something no longer present, reactivating or reembodying it as an object/image in and for the present, is here proposed as a (political) act of restitution and historical recontextualization. Examining the boundaries between past and present, original and copy (as well as originality and copyright), repetition and variation, authenticity and auraticity, presence and absence, canon and appropriation, durée and transience, the paper focuses on remediation, reinterpretation, and reconstruction as creative gestures and cultural promises in contemporary art practice, curatorship, and museology.

Abstract: In this paper Segmentation is one the most important process which decides the success of character recognition fashion. Segmentation is used to putrefy an image of a sequence of characters into sub images of individual symbols by segmenting lines and words. In segmentation image is partitioned into multiple corridor. With respect to the segmentation of handwritten words into characters it's a critical task because of complexity of structural features and kinds in writing styles. Due to this without segmentation these touching characters, it's delicate to fete the individual characters, hence arises the need for segmentation of touching characters in a word. Then we consider Marathi words and Marathi Numbers for segmentation. The algorithm is use for Segmentation of lines and also characters. The segmented characters are also stores in result variable. First it Separate the lines and also it Separate the characters from the input image. This procedure is repeated till end of train. Keywords: Image Segmentation, Handwritten Marathi Characters, Marathi Numbers, OCR.

The critical task of semioethics implies recognition of the common condition of dialogical interrelation and the capacity for listening, where dialogue does not imply a relation we choose to concede thanks to a sense of generosity towards the other, but on the contrary is no less than structural to life itself, a necessary condition for life to flourish, an inevitable imposition. With specific reference to anthroposemiosis, semioethics focuses on the concrete singularity of the human individual and the inevitability of intercorporeal interconnection with others. The singularity, uniqueness of each one of us implies otherness and dialogism. Semioethics assumes that whatever the object of study and however specialized the analysis, human individuals in their concrete singularity cannot ignore the inevitable condition of involvement in the destiny of others, that is, involvement without alibis. From this point of view, the symptoms studied from a semioethical perspective are not only specified in their singularity, on the basis of a unique relationship with the other, the world, self, but are above all social symptoms. Any idea, wish, sentiment, value, interest, need, evil or good examined by semioethics as a symptom is expressed in the word, the unique word, the embodied word, in the voice which arises in the dialectic and dialogical interrelation between singularity and sociality.

Driving is a safety-critical task that requires an alert and vigilant driver. Most research on the topic of vigilance has focused on its proximate causes, namely low arousal and resource expenditure. The present article aims to build upon previous work by discussing the ultimate causes, or the processes that tend to precede low arousal and resource expenditure. The authors review different aspects of fatigue that contribute to a loss of vigilance and how they tend to occur; specifically, the neurochemistry of passive fatigue, the electrophysiology of active fatigue, and the chronobiology of sleep-related fatigue.

AbstractQubit initialization is a critical task in quantum computation and communication. Extensive efforts have been made to achieve this with high speed, efficiency and scalability. However, previous approaches have either been measurement-based and required fast feedback, suffered from crosstalk or required sophisticated calibration. Here, we report a fast and high-fidelity reset scheme, avoiding the issues above without any additional chip architecture. By modulating the flux through a transmon qubit, we realize a swap between the qubit and its readout resonator that suppresses the excited state population to 0.08% ± 0.08% within 34 ns (284 ns if photon depletion of the resonator is required). Furthermore, our approach (i) can achieve effective second excited state depletion, (ii) has negligible effects on neighboring qubits, and (iii) offers a way to entangle the qubit with an itinerant single photon, useful in quantum communication applications.

AbstractThe COVID-19 pandemic has raised many intriguing questions both in the EU and globally, from the critical task of safeguarding lives to technical legal issues about competences to regulate health as well as the boundaries of emergency laws. This paper is interested in the connection between non-domination theory and the EU’s constitutional structure in the context of emergency laws. A key theme of the paper is that risk and emergencies are nothing new in an EU context, but concepts used by the legislator in a wide range of policy areas which give rise to a number of constitutional challenges. The paper sketches out the main characteristics of non-domination and republication theory and addresses the question of how and why the notion of non-domination may be useful for understanding the EU constitutionalism venture in the framework of risk and emergency laws.

AbstractThe digital culture has a profound influence on the formation of personal identity among the youth of Gens Y and Z. The networked society has strongly affected the process of forming an “inner identity,” a critical task in the adolescent period. The design of digital social media and apps can enslave youth in the “hive” and take away the solitude and resources needed for them to cultivate their “inner identity.” Therefore, there is a need for institutions such as school, family, and church to reinvent better ways to accommodate youth and engage them with digital media with responsibility and discernment.

This essay argues that Reinhold Niebuhr had a rich and theologically informed ecclesiology. The argument begins by briefly considering criticisms of Niebuhr’s ecclesiology before turning to a close reading of his writings on the American church. These writings are practical in nature and brief, which perhaps explains why they have received relatively little attention. In them, it becomes clear that Niebuhr embraced several doctrines associated with the Reformation churches, including a high view of the sacraments and the persistence of sin. For Niebuhr, grace and sin are central to the church’s identity as a communion of grace. Grace, he claims, has profound implications for the church in the United States. In a culture that emphasises merit, grace should give the church a critical task. Niebuhr’s vision of the church, then, is a sect-church, at once sacramental and critical. The essay concludes by sketching how Niebuhr’s ecclesiology relates to and informs contemporary American churches.

Abstract: In the industrial maintenance field, critical tasks are activities that can endanger operating processes and cause serious accidents if not performed correctly. These tasks are typically performed by professionals with a considerable level of knowledge and rely on prescribed procedures that flag the task, drawing the attention of task performers. Given the importance of reviewing work procedures and monitoring tasks for human error prevention, this study analyzed similarities and differences in the visual attention of expert and novice task performers while following procedures with and without flagging of a critical task. The study included 48 maintenance professionals, divided into two groups of performers: experts and novices. For attention analysis, eye-tracking technology was used to monitor their observation during the work procedure, recording data on time to first fixation, total fixation time and number of visits. The results indicate that in the procedure without flagging of the critical task, the numbers of fixations on and visits to the stages of the task were higher in the novice than in the expert group. In the flagged procedure, the visual attention of experts and novices was similar when considering all stages of the task. In conclusion, the tasks must be revised between the two groups, and the flagged procedure can be used as a guide for work monitoring, helping experts or novices to more easily select relevant information.
