description: High density polyethylene surfaces were exposed to the atmospheric post-discharge of a radiofrequency plasma torch supplied in helium and oxygen. Dynamic water contact angle measurements were performed to evaluate changes in surface hydrophilicity and angle resolved X-ray photoelectron spectroscopy was carried out to identify the functional groups responsible for wettability changes and to study their subsurface depth profiles, up to 9 nm in depth. The reactions leading to the formation of C–O, C=O and O–C=O groups were simulated by molecular dynamics. These simulations demonstrate that impinging oxygen atoms do not react immediately upon impact but rather remain at or close to the surface before eventually reacting. The simulations also explain the release of gaseous species in the ambient environment as well as the ejection of low molecular weight oxidized materials from the surface.

description: Laut Michel Foucault war das völlige Zusammenfallen von Ton und Bild, Stimme und Figur nicht nur eine entschieden neue Art der Organisation von Raum, Zeit und Erzählung, sondern zwang den Betrachter auch zu einer neuen Art von Aufmerksamkeit. Aus dieser Perspektive kann das Tonkino im Kontext der sowjetischen Kultur als Teil eines totalitären Spektakels gesehen werden, das alle medialen Strukturen umfasste und nicht nur die Errungenschaften Hollywoods, sondern auch die Idee des Gesamtkunstwerks in Form einer magisch operierenden Scheinmacht adaptierte. Bis Mitte der 1930er Jahre wurden in der UdSSR sowohl Stumm- als auch Tonfilme parallel produziert, und viele Filme wurden sogar in beiden Versionen veröffentlicht. 1928 erschien in der Zeitschrift Sovetskij ekran das Manifest der Regisseure Sergej Eisenstein, Vsevolod Pudovkin und Grigori Aleksandrov, in dem sie eine ganz eigene Vision des Tonfilms formulierten, die sich vom amerikanischen Modell abhob. Die ersten Versuche auf dem Gebiet des Tonfilms in der UdSSR der 30-er Jahre werden unter anderem am Beispiel solcher Filme analysiert wie Enthusiasmus (Donbass-Sinfonie) von Dsiga Wertow und Odna von Grigori Kosinzew.

description: The thesis titled ‘A qualitative exploration of individual and couple’s experiences of movement disorders’ explores experiences relevant to two common movement disorders; Parkinson's and cervical dystonia (CD). Section one presents a meta-ethnography, synthesising 19 qualitative studies relevant to the couple’s experience of Parkinson’s. The analysis of which produced three themes, which were: 1) Disruption of the couple’s roles and responsibilities and attempting to maintain the relationship; 2) Challenges to communication and closeness which can lead to increased resilience; and 3) Increased cognitive and behavioural symptoms leading to grief, burden and isolation. The findings highlight the challenges that couples experience and the individual and relational resources that support them to cope. The relevant strengths, weaknesses, and implications for clinical practice and future research are discussed. Section two presents a qualitative interpretative phenomenological analysis (IPA) study exploring the experience of diagnosis in CD. Six participants were interviewed, and their data analysed. The analysis produced three themes: 1) Losing control over one’s body and attempts to regain control: ‘You don't know what's going on and your whole life is kinda falling apart’; 2)Feeling powerless in response to the health system: ‘I had this change and I couldn't do anything about it, and nobody seemed to have any kind of solution’; 3) Mixed feelings upon diagnosis: ‘It's kinda like a relief, but scary at the same time’. The findings provide further insight and interpretation of the experience of diagnosis and highlight how this can be a significant and distressing experience. Clinical implications and suggestions for further study are discussed. Section three presents a critical appraisal where the author has discussed broader research issues and reflections on the reports contained in sections one and two. Considered, are the implications for the findings presented, their strengths, limitations, and suggestions for future research.
NEW MOLECULAR TOOLS FOR THE STUDY OF THE SHEEP TICK (IXODES RICINUS L.): DEVELOPMENT, APPLICATION AND EPIDEMIOLOGICAL IMPLICATIONS

description: The sheep tick, Ixodes ricinus, is the most important zoonotic vector in Europe; its dispersal potential and the relative importance of various vertebrate hosts it exploits, both essential to understand emergence of tick-borne diseases are virtually unknown. I applied two molecular approaches to 30 I. ricinus populations in the Province of Trento, Italy. A novel bloodmeal analysis Real-time HRMA protocol was developed and tested on questing nymphs. RAD-Seq was used for the first time on I. ricinus to individually genotype SNP loci in adult ticks. Bloodmeal analysis confirmed that rodents feed about 30% of tick larvae, but also illustrate that large mammals play a central role in feeding larval ticks. Since birds also feed about 15% ticks, the results of this analysis imply that larval ticks are carried long distances by their hosts; hence dispersal potential is high. In fact, population genetics support that investigated alpine populations are genetically admixed, confirming other phylogenetic studies showing that panmixia of I. ricinus population is a general phenomenon. This is the first study showing that dogs are important sheep tick hosts. As dogs feed a higher proportion of ticks in peri-urban forest, they may enhance the contact rate between human and infected ticks, by bringing them into human habitations and urban parks. My results have added new knowledge to tick dispersal and host use, which will be used to improve models of the spread of I. ricinus, and related pathogens, in new climatically suitable areas. My novel bloodmeal analysis protocol, which eliminates previous problems of contamination, could help to identify and explain local TBD dynamics in other areas of the EU.
Antipsoriatic Anthrones with Modulated Redox Properties, 1. Novel 10-Substituted 1,8-Dihydroxy-9(10H)-anthracenones as Inhibitors of 5-Lipoxygenase

description: The syntheses, the biological evaluation, and the structure-activity relationships of a novel series of l,8-dihydroxy-9(10H)-anthracenones bearing acyl-, alkyl-, or alkylidene-linked aromatic substituents in the 10-position are described. The phenylacyl and phenylalkylidene analogs were far more potent inhibitors of 5-lipoxygenase (5-LO) from bovine polymorphonuclear leukocytes (IC50 values in the 10- 7 M range) than the antipsoriatic drug anthralin, whereas phenylalkyl analogs were only weak inhibitors. Among the active compounds were both potent generators of hydroxyl radicals, as determined by deoxyribose degradation, and strong reducers of the stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH). However, several derivatives of this series maintained 5-LO inhibitory activity but did not generate hydroxyl radicals and were not reactive with DPPH . In particular, phenylacyl analogs were also 6 times more efficient in inhibition of lipid peroxidation in model membranes than anthralin. Structure-activity relationships have shown that the presence of free phenolic groups in the attached aromatic ring is beneficial but not required for 5-LO inhibitory potency. The inhibitory potency in the 10-phenylacyl series increased with the length of the acyl chain with three methylene units being the optimum, suggesting a specific enzyme interaction which would not be expected for nonspecific redox inhibitors.

description: Tunneling two level systems (TLS), present in dielectrics at low temperatures, have been recently studied for fundamental understanding and superconducting device development. According to a recent theory by Burin \textit{et al.}, the TLS bath of any amorphous dielectric experiences a distribution of Landau-Zener transitions if exposed to simultaneous fields. In this experiment we measure amorphous insulating films at millikelvin temperatures with a microwave field and a swept electric field bias using a superconducting resonator. We find that the maximum dielectric loss per microwave photon with the simultaneous fields is approximately the same as that in the equilibrium state, in agreement with the generic material theory. In addition, we find that the loss depends on the fields in a way which allows for the separate extraction of the TLS bath dipole moment and density of states. This method allows for the study of the TLS dipole moment in a diverse set of disordered films, and provides a technique for continuously inverting their population.

description: Low density polyethylene (LDPE) surfaces have been plasma-modified to improve their nanostructural and wettability properties. These modifications can significantly improve the deposition of subsequent layers such as films with specific barrier properties. For this purpose, we compare the treatments induced by two atmospheric plasma torches with different configurations (showerhead vs linear). The modifications of LDPE films in terms of chemical surface composition and surface morphology are evidenced by X-ray photoelectron spectroscopy, water contact angles measurements and atomic force microscopy. A comparison between the two post-discharge treatments is achieved for several torch-to-substrate distances (gaps), treatment times and oxygen flow rates in terms of etching rate, roughening rate, diffusion of oxygen into the subsurface and hydrophilicity. By correlating these results with the chemical composition of the post-discharges, we identify and compare the species which are responsible for the chemical surface functionalization, the surface roughening and etching.

description: By using an LC/API-MS system, it was demonstrated that dopamine condenses with acetaldehyde to give salsolinol which is further metabolized to produce 6-O-methylsalsolinol (isosalsoline) which is O- and N-methylated to provide salsolidine and N-methylisosalsoline, respectively, in several plant tissue cultures of Papaveraceae. Almost none of the 3-O-methoxytyramine formed from dopamine was metabolized into simple isoquinoline derivatives. Although salsolinol and 3-O-methoxytyramine were formed from dopamine, no O-methylatedsalsolinol was formed in tissue cultures of Cynanchum vincetoxicum (Asclepiadaceae). The results suggest that the O-methylating enzymes of salsolinol may be different to those of dopamine.

description: Massive multiple-inputmultiple-output (MIMO) systems, dense small-cells (SCs), and full duplex are three candidate techniques for next-generation communication systems. The cooperation of next-generation techniques could offer more benefits, e.g., SC in-band wireless backhaul in massive MIMO systems. In this paper, three strategies of SC in-band wireless backhaul in massive MIMO systems are introduced and compared, i.e., complete time-division duplex (CTDD), zero-division duplex (ZDD), and ZDD with interference rejection (ZDD-IR). Simulation results demonstrate that SC in-band wireless backhaul has the potential to improve the throughput for massive MIMO systems. Specifically, among the three strategies, CTDD is the simplest one and could achieve decent throughput improvement. Depending on conditions, with the self-interference cancellation capability at SCs, ZDD could achieve better throughput than CTDD, even with residual self-interference. Moreover, ZDD-IR requires the additional interference rejection process at the BS compared to ZDD, but it could generally achieve better throughput than CTDD and ZDD.

Societies Without Ancestors? Why Are So Few Graves Found in the European Upper Palaeolithic and Mesolithic?

description: Societies Without Ancestors? Why Are So Few Graves Found in the European Upper Palaeolithic and Mesolithic? Most specialists agree that the classical explanations (taphonomic and demographic factors; forms of treatment of the bodies leading to, all other things being equal, the non-preservation of remains) are not sufficient to explain the small number of burials and human remains known for the Upper Palaeolithic-Mesolithic sequence. The explanation could well lie in the preponderance, at that time, of a funerary system reflecting an assumed desire to remove and forget the dead, considered to be, at least for the most part, potentially harmful entities for the living. This system is that of »societies without ancestors«, or »ghost societies«, which we attempt to characterise in this article via a diversion through ethnology. From at least the Mesolithic onwards, it coexists with a second system, that of »ancestor societies«.

description: Nikolai Ostrowskis Debütroman "Wie der Stahl gehärtet wurde" war ein bedeutendes Werk im literarischen Kanon des sozialistischen Realismus, mit einer scheinbar klaren Trennung von Feinden und Freunden. In dem vorliegenden Beitrag wird diese Eindeutigkeit in Frage gestellt. Es wird argumentiert, dass der Erfolg und die propagandistische Nutzung des Romans gerade wegen seiner Mehrdeutigkeit möglich waren. Der Text wird im Kontext der andauernden Präsenz des christlichen Opfers sowie der Modifikationen christlicher Bildmuster in der Literatur des sozialistischen Realismus untersucht. Dazu wird Ostrovskys Roman mit den Begründungen für das Opfer Christi verglichen, die im Neuen Testament enthalten sind, wobei dem Christus-Hymnus besondere Aufmerksamkeit gewidmet wird. Es wird die Hypothese überprüft, dass ein ähnlicher Aufruf zur Selbsterniedrigung in Ostrovskys Roman zu finden ist und die sowjetische Propaganda dazu beigetragen hat, dass dieser Aufruf durch die Rezeptionsgeschichte dieses Textes zog.

description: The electronic band structure of iron pnictides exhibits four Dirac cones, which are due to crystal symmetry and orbital bonding orientation. This hallmark signature presents the pnictide family as an ideal candidate in the search for quasi-two-dimensional topological crystalline insulators. In this report, we explore interaction-induced topological phases which cannot be described by conventional local order parameters. Based on a model Hamiltonian our symmetry analysis shows that sponta- neous novel topological phases may be realized in compounds with tetragonal crystal field symmetry, where the electrons occupy the two degenerate t2g energy levels at low temperature. We identify two stable topological phases in the ground state, which emerge from spontaneous orbital current order. These currents are driven by electronic correlations caused by inter-orbital Coulomb interactions. The first topological phase is an anomalous orbital Hall phase, characterized by a nonzero Chern number, while the second topological phase has a vanishing Chern number, though with an extra Z2-like invariant that preserves parity. More specifically, the interaction-induced novel phase of the quasi-two-dimensional topological crystalline insulator is protected by mirror reflection symmetries and therefore may be realized in pnictides.

description: We introduce a new class of scalar-tensor theories that extend Horndeski, or "generalized galileon", models. Despite possessing equations of motion of higher order in derivatives, we show that the true propagating degrees of freedom obey well-behaved second-order equations and are thus free from Ostrogradski instabilities, in contrast to the standard lore. Remarkably, the covariant versions of the original galileon Lagrangians-obtained by direct replacement of derivatives with covariant derivatives-belong to this class of theories. These extensions of Horndeski theories exhibit an uncommon, interesting phenomenology: the scalar degree of freedom affects the speed of sound of matter, even when the latter is minimally coupled to gravity.

We show, for asymptotically large $d$, that any such induced subgraph has size density at most $2(\log d)/d$ with high probability. A matching lower bound is known for independent sets. We also prove the analogous result for sparse Erdős-Rényi graphs.

description: A number of acetoxy-substituted dibenzo[a,g]quinolizin-8-ones were synthesized by the reaction of 1-oxoisoquinolines with substituted homophthalic acid anhydride. All of the derivatives with acetoxy groups in positions 3 and 10 bind to the estrogen receptor. Relative binding affinities (RBA) ranged from 1.8 to 5.6 (estradiol: RBA = 100) when the substituent at C-6 was a short alkyl group. Introduction of additional oxygen functions in the 2- and/or 11-position decreased binding affinities. Analyses of the enantiomers of 6-methyl (6b) and 6-ethyl (6c) derivatives revealed that the receptor binding is mainly due to one optical isomer (e.g. (-)-6b, 9.9; (+)-6b, 0.6). In hormone-sensitive human MCF-7 breast cancer cells, compounds with one acetoxy group in each aromatic ring strongly inhibited cellular growth. Despite marked differences in receptor affinity, the enantiomers displayed similar activities in this cell culture. In hormone-independent MDA-MB 231 mammary tumor cells, only a weak cytostatic effect was recorded at 10-5 M. In the immature mouse uterine weight test, minimal estrogenic activity was observed. At higher doses, a significant anti-estrogenic effect became evident. It is assumed that the estrogen antagonism is responsible for the specific cytostatic effect in MCF-7 breast cancer cells.

I -Atome unter Bildung von (M-Hal')+- Ionen (m/z 133) hoher Intensität (70/12 eV; 1. und 2. FFR) und identischer Struktur (MIKE-CAD-Spektren). Die Fragmentionen bei m/z 133 aus o- Chlorphenyl-2-propanon (2a) und 2,2-Dimethyl-2,3-dihydro[fc]furan (11) sind von ähnlicher, aber nicht identischer Struktur. Die stoßaktivierten (2. FFR) (M-Br*)+-Ionen aus o-Bromphenyl-2-propanon (3a) und 1-Brom-lphenyl- 2-propanon (12) liefern praktisch deckungsgleiche Spektren. Die Hauptreaktion der (M-Hal')+-Ionen aus 2a-4a ist die Abspaltung von CO, das ausschließlich das C-Atom der Carbonylgruppe enthält (13C-Markierung). Der mechanistische Verlauf der Reaktionsfolge wird diskutiert (Abb. 5 und 8). In the gas phase, the phenyl-2-propanone molecules 2a-4a lose upon electron impact chloro-, bromo-, and iodo-radicals specifically at the orthoposition of the phenyl group giving rise to strong (M-Hal')+-ions (70/12 eV; 1st and 2nd FFR) of identical structure as confirmed by their MIKECAD- spectra. The daughter ions at m/z 133 from o-chlorophenyl-2-propanone (2a) and 2,2-dimethyl-2,3-dihydro[b]furane (11) are structurally similar but not identical (similarity index 99.8). The collisionally activated (2nd FFR) (M-Br')+-ions from o-bromophenyl-2-propanone (3a) and 1- bromo-1-phenyl-2-propanone (12) produce virtually congruent spectra. The most important subsequent fragmentation of the (M-Hal')+-ions from 2a-4a is the loss of CO which incorporates the C-atom of the carbonyl group exclusively (13C labelling). Mechanistic aspects of the fragmentation sequences are discussed (Figs. 5 and 8).

Conceptual Inadequacy of the Shore and Johnson Axioms for Wide Classes of Complex Systems

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: It is by now well known that the Boltzmann-Gibbs-von Neumann-Shannon logarithmic entropic functional ($S_{BG}$) is inadequate for wide classes of strongly correlated systems: see for instance the 2001 Brukner and Zeilinger's {\it Conceptual inadequacy of the Shannon information in quantum measurements}, among many other systems exhibiting various forms of complexity. On the other hand, the Shannon and Khinchin axioms uniquely mandate the BG form $S_{BG}=-k\sum_i p_i \ln p_i$; the Shore and Johnson axioms follow the same path. Many natural, artificial and social systems have been satisfactorily approached with nonadditive entropies such as the $S_q=k \frac{1-\sum_i p_i^q}{q-1}$ one ($q \in {\cal R}; \,S_1=S_{BG}$), basis of nonextensive statistical mechanics. Consistently, the Shannon 1948 and Khinchine 1953 uniqueness theorems have already been generalized in the literature, by Santos 1997 and Abe 2000 respectively, in order to uniquely mandate $S_q$. We argue here that the same remains to be done with the Shore and Johnson 1980 axioms. We arrive to this conclusion by analyzing specific classes of strongly correlated complex systems that await such generalization.

description: The conversion of CO2 and CH4 into value-added chemicals is studied in a new geometry of a dielectric barrier discharge (DBD) with multi-electrodes, dedicated to the treatment of high gas flow rates. Gas chromatography is used to define the CO2 and CH4 conversion as well as the yields of the products of decomposition (CO, O2 and H2) and of recombination (C2H4, C2H6 and CH2O). The influence of three parameters is investigated on the conversion: the CO2 and CH4 flow rates, the plasma power and the nature of the carrier gas (argon or helium). The energy efficiency of the CO2 conversion is estimated and compared with those of similar atmospheric plasma sources. Our DBD reactor shows a good compromise between a good energy efficiency and the treatment of a large CO2 flow rate.

We discuss this new property and describe certain classes of associative string functions. We also characterize the recently introduced preassociative functions as compositions of associative string functions with injective unary maps. Finally, we provide descriptions of the classes of associative and preassociative functions which depend only on the length of the input.

Chemical and physical effects of the carrier gas on the atmospheric pressure PECVD of fluorinated precursors
Creators: name: DUFOUR, Thierry
Publisher: name: figshare
Year: 2023
Subjects: classificationCode: 510602
subject: Plasma physics; fusion plasmas; electrical discharges

description: The atmospheric pressure PECVD deposition and texturization of hydrophobic coatings using liquid fluorinated C6F12 and C6F14 precursors are investigated. The effect of the carrier gas (argon and helium) is discussed in terms of the behavior of the gas phase and of the characteristics of the deposited film. Mass spectrometry measurements indicate that the fragmentation is higher with argon while helium reacts very easily with oxygen impurities leading to the formation of CxFyOz compounds. These observations are consistent with the chemical composition of the films determined by XPS and the variation in the deposition rate. Moreover, the streamers present in the argon discharge affect the morphology of the surface by increasing the roughness, which leads to the increase in the hydrophobicity of the coatings.

description: We show that the largest density of factor of i.i.d. independent sets on the d-regular tree is asymptotically at most (log d)/d as d tends to infinity. This matches the lower bound given by previous constructions. It follows that the largest independent sets given by local algorithms on random d-regular graphs have the same asymptotic density. In contrast, the density of the largest independent sets on these graphs is asymptotically 2(log d)/d. We also prove analogous results for Poisson-Galton-Watson trees, which yield bounds for local algorithms on sparse Erdos-Renyi graphs.

SaxFDM-Tagung

description: Die sächsische FDM-Landesinitiative SaxFDM ist eine seit 2019 beste­hende Bottom-up-Initiative von derzeit 22 sächsischen Forschungs­einrichtungen mit dem Ziel, die Vernetzung und Kooperation in Bezug auf das Forschungsdatenmanagement (FDM) im Freistaat voranzu­treiben. Die Ziele, Handlungsfelder und die grundlegende Organisation wurden in einem Strategiepapier definiert. SaxFDM wird von einem fünfköpfigen Sprecher:innenkreis aus Vertre-ter:innen verschiedener Einrichtungstypen geleitet und von einem wissenschaftlichen Beirat mit 13 Mitgliedern beraten. Das SaxFDM-Plenum trifft sich vierteljähr­lich. Diese Treffen sind offen für Interessierte aus allen sächsischen Forschungseinrichtungen. Zudem formierten sich verschiedene Ar­beitskreise, die auf Basis ehrenamtlicher Arbeit ausgewählte Themen­schwerpunkte (Wissenstransfer und Beratung, Gemeinsame Dienste und Tools, Öffentlichkeitsarbeit) bearbeiten und erste Angebote (z.B. das Veranstaltungsformat „Digital Kitchen“) entwickelt haben. Mit der Förderung des Projekts „SaxFDM – Etablierung einer ko­operativen Unterstützung für das Forschungsdatenmanagement im Freistaat Sachsen“, die seit Ende 2021 vom Sächsischen Staatsminis­terium für Wissenschaft, Kultur und Tourismus gewährt wird, ist es möglich, das Serviceangebot umfassend weiterzuentwickeln und aus­zubauen sowie Konzepte für nachhaltige und effektive Strukturen zu entwerfen. Um dies zu erreichen, ist ein dreiköpfiges Kompetenzteam als institutionsübergreifende Arbeitsgruppe seit März 2022 in der Landesinitiative aktiv.

description: In den späten 1930er Jahren wurde das historische Kino in der Sowjetunion zum wichtigsten Propagandainstrument. Bedeutende Regisseure erhielten historische Stoffe zugewiesen. Ferne Vergangenheit sowie die jüngste Geschichte wurden neu interpretiert. Im Frühjahr 1946 verlor das historische Kino seine bevorzugte Stellung zugunsten des neuen Genres historisch-biografischer Filme über bedeutende Wissenschaftler und Komponisten. Der gemeinsame Leitgedanke all dieser Filme war der Vorrang der nationalen Kultur und Wissenschaft. Das neue Genre entsprach den wachsenden nationalistischen Tendenzen und fügte sich in den politischen Hintergrund der Kampagnen gegen den Kosmopolitismus und die geringe Verehrung des Westens ein.

Synthesis and texturization processes of (super)-hydrophobic fluorinated surfaces by atmospheric plasma

description: The synthesis and texturization processes of fluorinated surfaces by means of atmospheric plasma are investigated and presented through an integrated study of both the plasma phase and the resulting material surface. Three methods enhancing the surface hydrophobicity up to the production of super-hydrophobic surfaces are evaluated: (i) the modification of a polytetrafluoroethylene (PTFE) surface, (ii) the plasma deposition of fluorinated coatings and (iii) the incorporation of nanoparticles into those fluorinated films. In all the approaches, the nature of the plasma gas appears to be a crucial parameter for the desired property. Although a higher etching of the PTFE surface can be obtained with a pure helium plasma, the texturization can only be created if O2 is added to the plasma, which simultaneously decreases the total etching. The deposition of CxFy films by a dielectric barrier discharge leads to hydrophobic coatings with water contact angles (WCAs) of 115°, but only the filamentary argon discharge induces higher WCAs. Finally, nanoparticles were deposited under the fluorinated layer to increase the surface roughness and therefore produce super-hydrophobic hybrid coatings characterized by the nonadherence of the water droplet at the surface.
Neutrino Magnetic Moments Meet Precision $N_{\rm eff}$ Measurements

description: In the early universe, Dirac neutrino magnetic moments due to their chirality-flipping nature could lead to thermal production of right-handed neutrinos, which would make a significant contribution to the effective neutrino number, $N_{\rm eff}$. We present in this paper a dedicated computation of the neutrino chirality-flipping rate in the thermal plasma. With a careful and consistent treatment of soft scattering and the plasmon effect in finite temperature field theories, we find that neutrino magnetic moments above $2.7\times 10^{-12}μ_B$ have been excluded by current CMB and BBN measurements of $N_{\rm eff}$, assuming flavor-universal and diagonal magnetic moments for all three generation of neutrinos. This limit is stronger than the latest bounds from XENONnT and LUX-ZEPLIN experiments, and comparable with those from stellar cooling considerations.

description: Through this choral tribute to Domenico Jervolino we hope to have reconstructed the breadth of his philosophical interests, his theoretical lines but above all the bonds of friendship and esteem that over the years have intertwined-in high Ricoeurian style-between several Italian and International figures. For this reason, this is a ‘choral’ remembrance and homage, a way of witnessing the esteem towards the scholar with whom interest and reflections have been shared over the years, in the conviction that to germinate them, they need to be share and participated among those who have a common vocation. A vocation (and the interest towards a reflection) that seeks in History, in Psychoanalysis, in the texts, places where to meet men and try to build together “shared worlds”, for others to inherit, within an infinite thread of interpretations.
