description: There are many papers written on the Two Envelopes Problem that usually study some of its variations. In this paper we will study and compare the most significant variations of the problem. We will see the correct decisions for each player and we will show the mathematics that supports them. We will point out some common mistakes in these calculations and we will explain why they are incorrect. Whenever an amount of money is revealed to the players in some variation, we will make our calculations based on the revealed amount, something that is not achieved in other papers.

description: Purpose: The factors that influence the evaluation of voice in adulthood, as well as the consequences of such evaluation on social interactions, are not well understood. Here, we examined the effect of listeners’ age and the effect of talker age, sex, and smoking status on the auditory-perceptual evaluation of voice, voice-related psychosocial attributions, and perceived speech tempo. We also examined the voice dimensions affecting the propensity to engage in social interactions.Method: Twenty-five younger (age 19–37 years) and 25 older (age 51–74 years) healthy adults participated in this cross-sectional study. Their task was to evaluate the voice of 80 talkers.Results: Statistical analyses revealed limited effects of the age of the listener on voice evaluation. Specifically, older listeners provided relatively more favorable voice ratings than younger listeners, mainly in terms of roughness. In contrast, the age of the talker had a broader impact on voice evaluation, affecting auditory-perceptual evaluations, psychosocial attributions, and perceived speech tempo. Some of these talker differences were dependent upon the sex of the talker and his or her smoking status. Finally, the results also show that voice-related psychosocial attribution was more strongly associated with the propensity of the listener to engage in social interactions with a person than auditory-perceptual dimensions and perceived speech tempo, especially for the younger adults.Conclusions: These results suggest that age has a broad influence on voice evaluation, with a stronger impact for talker age compared with listener age. While voice-related psychosocial attributions may be an important determinant of social interactions, perceived voice quality and speech tempo appear to be less influential.

description: Η ανάδυση της μετα-μαρξιστικής σκέψης υπήρξε αποτέλεσμα της πολυπαραγοντικής κρίσης της κλασικής μαρξιστικής παράδοσης, επιστέγασμα της οποίας αποτέλεσε η πτώση του «υπαρκτού σοσιαλισμού». Με αφετηρία το έργο των E. Laclau και C. Mouffe, καθώς και του «Ανοιχτού Μαρξισμού» με βασικό εκπρόσωπο τον J. Holloway, θα υποστηρίξουμε πως ο μετα-μαρξισμός συνιστά ένα σημείο ρήξης με τον μαρξισμό και όχι ένα εγχείρημα ανανέωσής του. Στο πλαίσιο αυτό, θα εστιάσουμε στις έννοιες της ενδεχομενικότητας, της ανοικτότητας, της ηγεμονίας, του πλουραλισμού, της ριζοσπαστικής δημοκρατίας, της ταυτότητας, που έρχονται σε άμεση ρήξη με θεμελιώδεις έννοιες του πυρήνα της μαρξιστικής θεωρίας. Επιδίωξη της παρούσας εργασίας είναι η ανάδειξη της σημασίας της παραπάνω διαπίστωσης, ενταγμένης στο πλαίσιο των κοινωνικών και πολιτικών ανταγωνισμών του ύστερου καπιταλισμού. Η κυριαρχία του νεοφιλελευθερισμού, η όξυνση των οικονομικών και κοινωνικών ανισοτήτων, και η αποδυνάμωση της Αριστεράς διεθνώς, συνιστούν άμεσες προκλήσεις για τη χάραξη μιας νέας ριζοσπαστικής στρατηγικής. Υπό το πρίσμα αυτό, είναι πράγματι εφικτή η κατασκευή ενός μετα-μαρξιστικού εννοιολογικού πλαισίου, ικανού να αντιπαρατεθεί και να ξεπεράσει τον μαρξιστικό πυρήνα, στην κατεύθυνση της ριζικής κοινωνικής αλλαγής;
description: The emergence of post-marxist thought was the result of the multi-level crisis of the classical Marxist tradition, the culmination of which was signalled by the fall of actually existing socialism. Focusing on the work of E. Laclau and C. Mouffe, as well as on so-called “Open Marxism” with J. Holloway as main representative, we will argue that post-marxism is not a project of renewal for marxism, but a decisive point of rupture with it. In this context, we will focus on the concepts of contingency, openness, hegemony, pluralism, radical democracy, identity that are in direct conflict with fundamental concepts of the core of Marxist theory. The aspiration of the present work is to highlight the importance of the above finding, within the framework of the social and political antagonisms of late capitalism. The dominance of neoliberalism, the deepening of economic and social inequalities, and the weakening of the Left worldwide are immediate challenges for the formulation of a new left radical strategy. In this light, is it possible to build a post-marxist conceptual framework, capable of confronting and overcoming the Marxist core, in the direction of radical social change?
Mapping the Surface of the Magnetar 1E 1048.1-5937 in Outburst and Quiescence Through Phase Resolved X-ray Spectroscopy

description: We model the pulse profiles and the phase resolved spectra of the anomalous X-ray pulsar 1E 1048.1-5937 obtained with XMM-Newton to map its surface temperature distribution during an active and a quiescent epoch. We develop and apply a model that takes into account the relevant physical and geometrical effects on the neutron star surface, magnetosphere, and spacetime. Using this model, we determine the observables at infinity as a function of pulse phase for different numbers and sizes of hot spots on the surface. We show that the pulse profiles extracted from both observations can be modeled with a single hot spot and an antipodal cool component. The size of the hot spot changes from $\approx 80^{\circ}$ in 2007, 3 months after the onset of a dramatic flux increase, to $\approx 30^{\circ}$ during the quiescent observation in 2011, when the pulsed fraction returned to the pre-outburst $\approx$ 65\% level. For the 2007 observation, we also find that a model consisting of a single 0.4 keV hot spot with a magnetic field strength of $1.8 \times 10^{14}$ G accounts for the spectra obtained at three different pulse phases but under predicts the flux at the pulse minimum, where the contribution to the emission from the cooler component is non-negligible. The inferred temperature of the spot stays approximately constant between different pulse phases, in agreement with a uniform temperature, single hot spot model. These results suggest that the emitting area grows significantly during outbursts but returns to its persistent and significantly smaller size within a few year timescale.

description: The constituent parts of a quantum computer are inherently vulnerable to errors. To this end we have developed quantum error-correcting codes to protect quantum information from noise. However, discovering codes that are capable of a universal set of computational operations with the minimal cost in quantum resources remains an important and ongoing challenge. One proposal of significant recent interest is the gauge color code. Notably, this code may offer a reduced resource cost over other well-studied fault-tolerant architectures using a new method, known as gauge fixing, for performing the non-Clifford logical operations that are essential for universal quantum computation. Here we examine the gauge color code when it is subject to noise. Specifically we make use of single-shot error correction to develop a simple decoding algorithm for the gauge color code, and we numerically analyse its performance. Remarkably, we find threshold error rates comparable to those of other leading proposals. Our results thus provide encouraging preliminary data of a comparative study between the gauge color code and other promising computational architectures.

PIDs, Types and the Semantic Web

Subjects: subject: 80403 Data Structures

description: PID Information Types are becoming a crucial role in scientific data
management because they can provide state (what) and binding (where)
information about digital objects as attributes of the PID. This is a
similar but much more flexible approach than the well known mime type
characterization, because both of these types concepts allow to decide
about preconditions for processes in advance and before touching the
data. One aspect of this is the need for standards and correctness of
the used types to ensure reliability for the processes operating on the
digital objects. This requires registries and schemas for PID InfoTypes
and suggests an automated schema generation process. Such a process in
combination with data type registries will be described in more detail
in the intended talk. Another aspect of PID InfoTypes is its intrinsic
grammar as subject-predicate-object triple, with the PID as subject, the
type as predicate and its value (often again a PID) as object in this
relation. Given the registration of types and the proposed syntactical
rigidness of the value, guaranteed by the schema, together with the use
of PIDs in subject and predicate, the type concept has the ability to
overcome the fuzziness and lack of reliability of semantic web
categories with its URL references and possibly changing locations and
content. The intended talk will also describe this approach in more
detail, discusses the differences to linked data and describes some
necessary technological developments for the type concept to keep up
with the possibilities currently provided by the semantic web.

description: Σκοπός της μεταπτυχιακής διπλωματικής εργασίας ήταν η μελέτη της καταστρατήγησης της νομοθεσίας για την προσωρινή απασχόληση μέσω της σύμβασης έργου. Αρχικά έγινε μία εισαγωγή στις βασικές έννοιες του δανεισμού προσωπικού και οριοθετήθηκε ο γνήσιος δανεισμός. Στην συνέχεια αναλύσαμε την νομοθετική ρύθμιση της προσωρινής απασχόλησης, τα εννοιολογικά της στοιχεία και τις έννομες σχέσεις που αναπτύσσονται μεταξύ των τριών εμπλεκόμενων μερών. Ακολούθως αναλύθηκε εκτενώς το πως λειτουργεί η σύμβαση έργου στο εργατικό δίκαιο και εξετάστηκε η καταστρατήγηση της νομοθεσίας για την προσωρινή απασχόληση μέσω του outsourcing. Μετέπειτα έγινε μια εκτενής αναφορά στις ενδείξεις που μπορούν οδηγήσουν στην διάκριση μεταξύ της γνήσιας σύμβασης έργου και της σύμβασης έργου που υποκρύπτει παράνομη ενοικίαση προσωπικού. Καταληκτικά, προτάθηκαν τρόποι αντιμετώπισης του φαινομένου ώστε να θωρακιστεί η εργασία των προσωρινά απασχολουμένων.
description: The aim of the Master's thesis was to study the destruction of the legislation on temporary agency work through the project contract. First, an introduction to the basic concepts of personnel lending was made and the hiring out of employees was defined. We then analysed the legal regulation of temporary employment, its conceptual elements and the legal relationships that develop between the three parties involved. Next, we analysed at length how the project contract works in labour law and examined the circumvention of temporary agency work legislation through outsourcing. We then discussed at length the indications that can lead to the distinction between a genuine project contract and a project contract that implies illegal hiring of out of employees. In conclusion, ways of dealing with the phenomenon were proposed to shield the work of temporary workers.

description: We consider the impact of quantum effects on electron dynamics in a plane linearly polarized standing wave with relativistic amplitudes. For this purpose analysis the Lyapunov characteristic exponent spectrum with and without allowance for the classic radiation reaction force has been analyzed. Based on this analysis it is concluded that the contraction effect of phase space in the stochastic regime due to the radiation reaction force in the classical form doesn't occur when the quantum nature of hard photon emission is taken into account. It is shown that electron bunch kinetics has a diffusion solution rather than the d'Alambert type solution as in the classic description.It is also revealed that the electron motion can be described using the Markov chain formalism. This method gives exact characteristics of electron bunch evolution, such as motion of the center of mass and electron bunch dimensions.

Συμπληρωματικά, χρησιμοποιήθηκαν εργαλεία Web 2.0 για την παρατήρηση και ανάλυση έργων τέχνης του ζωγράφου Vincent Van Gogh μέσα από δραστηριότητες που στοχεύουν στην βελτίωση των γλωσσικών και επικοινωνιακών δεξιοτήτων των μαθητών για χρήση σε περιβάλλον μεικτής μάθησης. Προτείνεται η δημιουργία ψηφιακού υλικού με την αξιοποίηση των εργαλείων που έχουν στα χέρια τους οι εκπαιδευτικοί ώστε να αλλάξει ριζικά ο μονοδιάστατος τρόπος που γίνεται η διδασκαλία των αγγλικών ως ξένη γλώσσα στη χώρα μας.
description: Blended learning is steadily gaining ground in education as it offers flexibility and efficiency by combining face-to-face and online learning. At the same time, it maintains the direct communication with the teacher, the use of technology and various digital tools that enhance the learning process, the interaction and autonomy of students. This paper studies blended learning in the context of foreign language education. Moreover, learning management systems and digital tools for skill development in EFL are presented. Lastly, a course for first year High School students, which was developed on the Moodle platform, is proposed. The tools and capabilities that the platform offers were used to create a hybrid course for teaching English as a foreign language that promotes student collaboration and at the same time adapts to their individual learning needs. Web 2.0 tools were used to observe and analyze Vincent Van Gogh’s works of art and activities were created aiming at improving students' language and communication skills in a blended learning environment. It is highly recommended to create digital material by making use of the tools that are available to teachers to radically change the one-dimensional way of teaching English as a foreign language in our country.

Second, I present some preliminary operational questions about where is available the World Health Organization's (WHO) recent ethics guidelines on the emergency use of unproven interventions outside clinical trials (the MEURI framework) and if they are being used for the current monkeypox public health emergency of international concern. Third, I introduce two fundamental questions on the MEURI framework, namely, what is MEURI and what is the intended scope of the MEURI framework? Finally, I give a quick overwiew of the ethical criteria of the MEURI framework.

description: Στόχος της διπλωματικής αυτής εργασίας είναι η ανάλυση του τρόπου με τον οποίο αρχαίοι Έλληνες φιλόσοφοι ενσωματώνουν το χρόνο στη φυσική τους μελέτη, καθώς και η σύνδεσή του με τον άνθρωπο. Αρχικά, εξετάζεται η ορφική παράδοση, κατά την οποία ο αγέραστος χρόνος ανήκει στις πρωταρχικές θεότητες και γεννά το κοσμικό αυγό από το οποίο προκύπτει ο φυσικός κόσμος. Για τον Αναξίμανδρο ο χρόνος αποτελεί κομβικό κομμάτι του σύμπαντος, που παρακολουθεί και θέτει όρια στην εναλλαγή των αντιτιθέμενων κοσμικών δυνάμεων, έτσι ώστε να επιβληθεί η ισότητα μεταξύ τους και η κοσμική δικαιοσύνη. Εν συνεχεία, ο Ηράκλειτος συνδέει το χρόνο με τόσο με τον υπερβατικό Λόγο και την ένυλη μορφή του πυρός, όσο και με την κίνηση. Παρουσιάζεται ως το παιδί που με το παιχνίδι του εξουσιάζει το κοσμικό γίγνεσθαι. Με τον Πλάτωνα εκκινεί μία πιο εντατική προσπάθεια καθορισμού του χρόνου, ο οποίος ορίζεται ως εικόνα που ανήκει στο φυσικό κόσμο, κινείται μιμούμενη την αιωνιότητα των άυλων Ιδεών και ταυτίζεται με την ημερήσια τακτική περιφορά του παντός. Τέλος, στον Αριστοτέλη ο χρόνος συσχετίζεται με την ευρύτερη έννοια της κίνησης, με το μέγεθος που την πραγματοποιεί αλλά και με την αντιληπτική ανθρώπινη ικανότητα. Πρόκειται για τον αριθμό που εκλαμβάνεται με βάση το πρότερο και ύστερο στην κίνηση.
description: The aim of this paper is to discover the way that the philosophers of greek antiquity speak of time and its relation to nature and the humans. First of all, in the Orphic theogonies time is considered one of the first deities and the maker of the cosmic egg, out of which hatches the physical world. For Anaximander, time belongs to the world and its role is to attend the inequity and bring the cosmic balance and justice. Meanwhile, Heraclitus relates time to Logos, to elemental fire and to change in general. For him, time is like a child which, by playing its game, rules the world. Plato also speaks of time in its connection to the physical world in which it partakes, as a moving image of the constantly unmoved Forms. Lastly, the paper is completed with Aristotle's interpretation, in which time refers to change and the magnitude that actualizes the motion.

description: Objectives: To measure heavy metal concentrations among Kenyan youth and quantify associations with sociocultural, demographic, and health factors as well as anthropometry. Methods: Using data from a study of semi-nomadic pastoralists in Samburu County, Kenya, we measured blood concentrations of lead (Pb), mercury (Hg), and cadmium (Cd) in 161 adolescents. We identified sociocultural, demographic and health characteristics associated with each metal and quantified the association between metals and adolescent anthropometry. Results: Median blood concentrations of Pb, Cd, and Hg were 1.82 µg/dL, 0.24 µg/L and 0.16 µg/L, respectively. Place of residence (highlands vs lowlands) was a determinant of metal concentrations. Hg was inversely related to anemia, and metals were not associated with anthropometry. Conclusions: In this population of Samburu adolescents, median Pb and Cd blood concentrations were higher than other North American or European biomonitoring studies. These findings motivate further investigation into the environmental sources of metals in this community.
Indirect band gap in graphene from modulation of the Fermi velocity

description: In this work we study theoretically the electronic properties of a sheet of graphene grown on a periodic heterostructure substrate. We write an effective Dirac equation, which includes a dependence of both the band gap and the Fermi velocity on the position, due to the influence of the substrate. This way, both bandgap and Fermi velocity enter the Dirac equation as operators. The Dirac equation is solved exactly and we find the superlattice minibands with gaps due to the breaking of translational symmetry induced by the underlying heterostructure. The spatial dependence of the Fermi velocity makes the band gap be indirect, bringing about interesting possibilities for applications in the design of nanoelectronic devices. In the limit of constant Fermi velocity we obtain a band structure, with direct band gap, very close to the one previously found in the literature, obtained using the transfer matrix method.

description: Child undernutrition and natural disasters are major public health concerns in Bangladesh, but research into their relationship is lacking. This study assessed the association between residential district multi-hazard-risk and undernutrition among children aged less than 5 years (under-5) in Bangladesh. Data for 22,055 under-5 children were extracted from the 2019 Multiple Indicator Cluster Survey of Bangladesh. Multi-hazard risk was categorized as low (score<10), moderate (score 10–20), and high (score>20) using a combined score of four major hazards: tornado, cyclone, earthquake, and flood. We found that children from high multi-hazard risk districts were 19% more likely to be stunted and 23% more likely to be underweight compared to low-risk districts. However, wasting was not associated with multi-hazard risk. Strategies such as agricultural adaptation and coping mechanisms, long-term post-disaster nutritional response, extended periods of relief supports, and enhanced quality maternal and child care services may help to reduce undernutrition burdens in Bangladesh.

description: In prophet Daniel’s first vision, specifically in Dan. 7,13, the form of the Son of Man, which is examined in this paper, is presented. The whole of Dan. 7 is characterized by apocalyptic prophecy and seems to have influenced later texts of jewish literature, which adopted and messianically interpreted the form of the Son of Man. In the era of the New Testament, Jesus Christ identifies himself with the Son of Man. In the narratives of the four Gospels, we noticeably find numerous references to the Son of Man, which are connected to the work and mission of the Lord, but also to important events of the Divine Economy. An important key to understanding both the Old and New Testament passages, which refer to the Son of Man, are of course the relevant interpretations of the church fathers, as well.

We asked 4338 women whether they had been in ‘an accident at work, even if it did not require medical treatment’, and the number of accidents throughout their working life, type of injury and whether it occurred within the last 12 months. Results. Over one-fifth (21.8%) of working-age mothers reported having at least one occupational injury throughout their working life. Wounds and superficial injuries were the most frequently reported types of occupational injuries (11.0%), followed by dislocated bones and joints, sprains and strains (10.7%). Women who reported a history of occupational injuries also had a higher likelihood of reporting a work-related health problem (adjusted odds ratio [OR] = 2.64; 95% confidence interval [CI] [2.27, 3.07]) and of having a partner who also reported an occupational injury throughout their working life (adjusted OR = 1.86; 95% CI [1.33, 2.62]). Associations remained fairly stable across all outcomes. Conclusions. Our findings point towards a broadened understanding of occupational injury consequences and research focusing on family-level factors that account for the embeddedness of workers in households.

description: Η παρούσα ερευνητική εργασία επιχειρεί να αναλύσει τη μεταστροφή που υφίσταται η προβολή λόγω της συνεχώς αυξανόμενης χρήσης των νέων τεχνολογικών εργαλείων και των μέσων κοινωνικής δικτύωσης (social media). Πεδίο μελέτης και εξέτασης της παραπάνω ιδέας αποτελεί η τέχνη και ο θεωρητικός λόγος που δομείται γύρω από αυτή. Συνοπτικά, η μελέτη διαρθρώνεται σε τρία στάδια. Το πρώτο στάδιο αφορά στον καθορισμό του θεωρητικού πλαισίου. Ορίζεται η εννοιολογική προσέγγιση των θεωρητικών όρων που χρησιμοποιούνται και αναλύονται οι προβληματισμοί που εγείρονται. Το δεύτερο στάδιο αφορά στην παρουσίαση και ανάλυση συγκεκριμένων εικαστικών εκθέσεων και επιμέρους έργων, τα οποία παρουσιάζουν άμεση ή έμμεση θεματική συνάφεια με τα ζητήματα που θίγονται στη μελέτη. Στο τρίτο στάδιο γίνεται μια κριτική αποτίμηση της θεωρίας και της πράξης (της τέχνης και των επιμελητικών πρακτικών) προκειμένου να οδηγηθούμε στα συμπεράσματα. Η αφορμή της έρευνας έγκειται στις προσωπικές εμπειρίες και στους συλλογικούς προβληματισμούς που αναδύθηκαν κατά την πανδημία του CoVid-19, η οποία στο συγκεκριμένο πλαίσιο προσεγγίζεται ως ένα συνδημικό φαινόμενο.
description: This research attempts to analyse the shift in visibility due to the ever-increasing use of new technological tools and social media. The field of study of this idea is art and the theoretical discourse structured around it. In summary, the study is articulated in three stages. The first stage concerns the definition of the theoretical framework, its conceptual approach of the theoretical terms used and the concerns raised. The second stage concerns the presentation and analysis of specific art exhibitions and artworks which present, directly or indirectly, a thematic relevance to the issues raised in the study. The third stage is a critical evaluation of theory and practice (art and curatorial practices) in order to arrive at conclusions. The motivation for the research lies in personal experience and collective reflections that emerged during the CoVid-19 pandemic, which in this context is approached as a syndemic phenomenon.

description: Purpose: The factors that influence the evaluation of voice in adulthood, as well as the consequences of such evaluation on social interactions, are not well understood. Here, we examined the effect of listeners’ age and the effect of talker age, sex, and smoking status on the auditory-perceptual evaluation of voice, voice-related psychosocial attributions, and perceived speech tempo. We also examined the voice dimensions affecting the propensity to engage in social interactions.Method: Twenty-five younger (age 19–37 years) and 25 older (age 51–74 years) healthy adults participated in this cross-sectional study. Their task was to evaluate the voice of 80 talkers.Results: Statistical analyses revealed limited effects of the age of the listener on voice evaluation. Specifically, older listeners provided relatively more favorable voice ratings than younger listeners, mainly in terms of roughness. In contrast, the age of the talker had a broader impact on voice evaluation, affecting auditory-perceptual evaluations, psychosocial attributions, and perceived speech tempo. Some of these talker differences were dependent upon the sex of the talker and his or her smoking status. Finally, the results also show that voice-related psychosocial attribution was more strongly associated with the propensity of the listener to engage in social interactions with a person than auditory-perceptual dimensions and perceived speech tempo, especially for the younger adults.Conclusions: These results suggest that age has a broad influence on voice evaluation, with a stronger impact for talker age compared with listener age. While voice-related psychosocial attributions may be an important determinant of social interactions, perceived voice quality and speech tempo appear to be less influential.

description: Objective. Office workers are commonly exposed to work-related musculoskeletal pain. This study investigated the individual and work-related risk factors linked to musculoskeletal pain and pain-related disability among Turkish office workers who work using computers. Methods. One-hundred and fifty office workers were included. Data were collected using an online survey with a combination of the Nordic musculoskeletal questionnaire, Oswestry disability index (ODI), neck disability index (NDI) and disabilities of the arm, shoulder, and hand questionnaire short-form (Q-DASH). The participants were divided into four subgroups: no pain (n = 26), lower back pain (n = 37), neck pain (n = 49) and upper-extremity pain (n = 38). Results. There were differences between subgroups in terms of the condition that feet touch the floor and the condition that the keyboard, mouse and wrist are in a straight line (p = 0.013 and p = 0.025, respectively). Working years was correlated with the ODI score (ρ = 0.802, p = 0.041). There was also a significant correlation between the NDI score and working hours (ρ = 0.415, p = 0.003), while Q-DASH was correlated with body mass index and working years (ρ = 0.406, p = 0.014, and ρ = 0.327, p = 0.043, respectively). Conclusions. Pain-related disability was associated with various risk factors such as physical inactivity, body mass index, working hours, working years and workplace ergonomics in the office workers.

description: Aim: To identify implementation strategies and safety outcomes (adverse events) of community-based physical activity interventions for adolescents and adults with complex cerebral palsy (CP). Method: Five electronic databases were systematically searched to April 2022. Data were extracted on the implementation and safety of physical activity interventions for adolescents and adults with CP, classified in Gross Motor Function Classification System (GMFCS) levels IV and V, delivered in a community setting. Results: Seventeen studies with 262 participants (160 participants classified in GMFCS levels IV or V) were included. Community settings included schools (n = 4), participants' homes (n = 3), gymnasia (n = 2), swimming pools (n = 2), and other settings (n = 4). Most studies specified medical or safety exclusion criteria. Implementation strategies included pre-exercise screening, use of adapted equipment, familiarization sessions, supervision, physical assistance, and physiological monitoring. Attendance was high and attrition low. Nine studies reported non-serious, expected, and related events. Four studies reported minor soreness and four studies reported minor fatigue post-exercise. Serious adverse events related to exercise were infrequent (reported for 4 of 160 participants [<2%]: three participants withdrew from an exercise programme and one participant ceased exercise for a short period). Most frequently reported was pain, requiring temporary exercise cessation or programme change, or study withdrawal (three participants). Interpretation: For most adolescents and adults with CP classified in GMFCS levels IV and V, physical activity interventions can be safely performed in a community setting, without post-exercise pain or fatigue, or serious adverse events. What this paper adds: Supervised community-based physical activity interventions can be safely performed by people with complex cerebral palsy. Post-exercise pain or fatigue was not common among those classified in Gross Motor Function Classification System levels IV or V. Serious adverse events are infrequent when exercising in community settings, with safety strategies.

description: We study the generation of magnetic field in the primordial plasma of the standard model (SM) particles at temperature $T>80$~TeV much higher than the electroweak scale. It is assumed that there is an excess number of right-handed electrons over left-handed positrons in the plasma. Using the Berry-curvature modified kinetic theory to incorporate the effect of the Abelian anomaly, we show that this chiral-imbalance leads to generation of hyper-magnetic field in the plasma in both the collision dominated and the collisionless regimes. It is shown that in the collision dominated regime the chiral-vorticity effect can generate finite vorticity in the plasma together with the magnetic field. Typical strength of the generated magnetic field is $10^{27}$~Gauss at $T\sim 80$~TeV with the length scale $10^5/T$ whereas the Hubble length scale is $10^{13}/T$. Further the instability can also generate the magnetic field of order $10^{31}$~Gauss at typical length scale $10/T$. But there may not be any vorticity generation in this regime. We show that the estimated values of the magnetic field are consistent with the bounds obtained from present observations.

description: Background: It is unclear whether moderate or less functional tricuspid regurgitation (TR) should be repaired during surgery for degenerative mitral valve (MV) disease. We studied the natural course of unaddressed moderate or less TR and identified risk factors for TR progression after surgery for degenerative MV disease. Methods: From 2001 to 2011, 2,982 patients with isolated degenerative MV disease and no evidence of coronary artery disease underwent MV surgery. To generate an enriched sample of patients with TR, by random selection 200 patients without TR, 197 with mild TR, and 177 with moderate TR were studied. A total of 1,150 echocardiograms were available for longitudinal analysis of TR progression after surgery in 550 of these 574 patients. Results: Overall prevalence of severe TR was 1.1%, 2.2%, 3.6%, and 4.4% by 1, 3, 5, and 7 years, respectively. Patients with moderate preoperative TR were more likely to progress to severe TR by 7 years (8.6%) than those with mild TR (3.2%) or no TR (1.3%) preoperatively (p p = 0.03), shorter right ventricular base-to-apex length (p = 0.0004), smaller tethering area (p = 0.01), older age, and preoperative heart failure. During follow-up, no patient underwent TV intervention. Conclusion: Routine repair of moderate or less functional TR during surgery for degenerative MV disease does not appear to be warranted, because progression to severe TR is uncommon. Instead, we suggest a tailored approach, reserving TR repair during surgery for degenerative MV disease for patients with known risk factors.
