AbstractWe analyse the phenomenological effects of a varying Dark Energy (DE) effective speed of sound parameter, $$c^{2}_{\text {sd}}$$ c sd 2 , on the cosmological perturbations of three phantom DE models. Each of these models induce a particular abrupt future event known as Big Rip (BR), Little Rip (LR), and Little Sibling of the Big Rip (LSBR). In this class of abrupt events, all the bound structures in the Universe would be ripped apart at a finite cosmic time. We compute the evolution of the perturbations, $$f\sigma _{8}$$ f σ 8 growth rate and forecast the current matter power spectrum. We vary the $$c^{2}_{\text {sd}}$$ c sd 2 parameter in the interval [0, 1] and compute the relative deviation with respect $$c^{2}_{\text {sd}}=1$$ c sd 2 = 1 . In addition, we analyse the effect of gravitational potential sign flip that occurs at very large scale factors as compared with the current one.

This report documents a case of sinus bradycardia in a hospitalised 27-month-old girl with a history of moderate persistent asthma, recent suspected viral respiratory infection and suspicion for multisystem inflammatory syndrome in children (MIS-C). This patient developed profound sinus bradycardia during her hospitalisation despite an overall well clinical appearance and good outcome. Reports of bradycardia related to COVID-19 infection are few but growing in number. In this article, we discuss what has been observed in the literature about bradycardia in relation to COVID-19 and MIS-C. We also propose sinus bradycardia as a potential sign of MIS-C with recent respiratory symptoms, which would warrant close follow-up of such patients.

The prefrontal cortex (PFC) is thought to control activity in the noradrenergic locus coeruleus (LC). Prior anatomical and prefrontal stimulation studies demonstrated the potential for PFC-LC interactions; however, it is unknown what types of PFC activity affect the LC. Here, we show that transient increases in PFC high γ power and associated changes in PFC unit-pair synchrony are a potential sign of top-down control over the LC.

For a start, the present study tackles the language of affection in the Qur’an and its role in managing unhealthy personality. Primarily, it provides a full-scale model for programming unhealthy mindsets. The model uses linguistic and neurological tools in the process of analysis. Affectional language is a case in point that shows how language, emotions, and cognition interact to reflect each other. The study highlights the effective role of affectional language in shaping minds. In the same vein, a typical example for the neurological programming process is the Qur’anic representation of the attitudes of some believers at the time of the Prophet Muħammad (PBUH) after a specific battle. This representation reports the initial reaction of the believers which is emotionally shaped. Also, it helps in making proper reactions which are shaped according to the normal pathways of thinking. The process of shaping cognition is carried out according to specific neurological strategies that include the proper process of sensation, retrieval of the previous experience, neuroplasticity, and acceptance. Also, these strategies include self-compassion and compassion for others. Adding to its motivational role in the promotion of forgiveness, it plays the same motivational role for doing justice. Accordingly, the study concludes that the discourse of affection plays an effective role in shutting the door on any potential sign of the hurt-perceived and the righteous indignation reactions. Furthermore, it combats radicalism and extremism in a way that ends all forms of violence.

Each element of space is a potential sign or it can become thanks to the author’s intentions. Sign and symbol issues are used in design for the development of the area around  St. Urszula Ledóchowska church in Lublin. The work defines the concept of a church garden as well as features and functions of a welldesigned object. The fieldwork consisted of carrying out  a detailed dendrological inventory and assessing the condition of existing facility. Then,  a conceptual design was developed, which proposed a new selection of plants with the preservation of some existing trees. The surface has been completely changed and elements of small architecture have been added. The area was divided into three zones: representative, contemplative and relaxing. The whole idea is to serve the clergy and parishioners, while being  a vote of gratitude to St. Urszula Ledóchowska.

Chapter 1 explores laughter’s changing status as a topic of intellectual debate in the 1100s. Investigating a wide range of theological, monastic, philosophical, rhetorical, satirical, and medical texts available to Henry II’s courtiers, the chapter suggests that by the end of the century laughter was becoming a sign of embodied moral power. Whereas laughter had previously carried diabolical associations, and had been forbidden to monks, condemned by preachers, and reproved by theologians, it now became a monastic virtue, a confirmation of good health, and a potential sign of God’s presence. These ideas of moral laughter were enabled, above all, by a series of shifts in attitudes towards the body. As theologians devised new repertoires of spiritual emotions and gestures, influential monks such as Bernard of Clairvaux (d.1153) were able to allocate laughter a role as an expression of the highest internal grace.
