description: Στην παρούσα εργασία σε πρώτο στάδιο τροποποιήθηκε η χιτοζάνη και το αλγινικό οξύ δημιουργώντας εμβολιασμένα συμπολυμερή με πολυ(μεθακρυλικό ύδροξυαιθυλεστέρα) και μελετήθηκαν με διάφορες τεχνικές. Στη συνέχει μελετήθηκε η διαλυτότητα τους, ικανότητα διόγκωσης τους και υδρόλυσης τους. Τα υλικά αυτά στη συνέχεια με τη χρήση της ιοντικής πηκτωματοποίησης παρήγαγαν νανοσωματίδια για τη δημιουργία φαρμακοτεχνικών μορφών της διφαινυδραμίνης. Στη συνέχεια, ακολούθησε ο πλήρης χαρακτηρισμός των νανοσωματιδίων που παρασκευάστηκαν με χρήση φασματοσκοπίας υπερύθρου, κρυσταλλογραφίας ακτίνων Χ και ηλεκτρονικής μικροσκοπίας σάρωσης. Τέλος αποδείχτηκε πως η μορφολογία και τα χαρακτηριστικά των φορέων όπως και τα χαρακτηριστικά μεγέθους και ενθυλάκωσης των νανοσωματιδίων επηρεάζουν την απελευθέρωση της διφαινυδραμίνης. Παράλληλα, οι νανοφορείς εμφανίζουν απόκριση σε μεταβολές του pH καθώς διαφοροποιείται η συμπεριφορά αποδέσμευσης τους σε όξινο και βασικό pH.
description: In this work pure chitosan and alginic acid were copolymerized with poly ( hydroxyethyl methacrylate ) and their derivatives were studied by various techniques such as FT-IR, XRD. Accordingly, their swelling ability, solubility and hydrolysis were also investigated. These materials using ionic gelation method produced nanoparticles in order to create formulations of diphenhydramine HCL. The prepared nanoparticles were characterized using infrared spectroscopy, X-ray diffraction and scanning electron microscopy. Finally it was proved that the morphology and characteristics like the size and encapsulation of nanoparticles affect the release of diphenhydramine. Meanwhile, different release behavior of nanocarriers in acidic and basic pH proved their pH- responsiveness.

description: Reactivity is an essential property of a synchronous program. Informally, it guarantees that at each instant the program fed with an input will `react' producing an output. In the present work, we consider a refined property that we call ` feasible reactivity'. Beyond reactivity, this property guarantees that at each instant both the size of the program and its reaction time are bounded by a polynomial in the size of the parameters at the beginning of the computation and the size of the largest input. We propose a method to annotate programs and we develop related static analysis techniques that guarantee feasible reactivity for programs expressed in the S-pi-calculus. The latter is a synchronous version of the pi-calculus based on the SL synchronous programming model.

description: Ultra-hot Jupiters are the hottest exoplanets discovered so far. Observations begin to provide insight into the composition of their extended atmospheres and their chemical day/night asymmetries. Both are strongly affected by cloud formation. We explore trends in cloud properties for a sample of five giant gas planets: WASP-43b, WASP-18b, HAT-P-7b, WASP-103b, and WASP-121b. This provides a reference frame for cloud properties for the JWST targets WASP-43b and WASP-121b. We further explore chemically inert tracers to observe geometrical asymmetries, and if the location of inner boundary of a 3D GCM matters for the clouds that form. The large day/night temperature differences of ultra-hot Jupiters cause large chemical asymmetries: cloud-free days but cloudy nights, atomic vs. molecular gases and respectively different mean molecular weights, deep thermal ionospheres vs. low-ionised atmospheres, undepleted vs enhanced C/O. WASP-18b, as the heaviest planet in the sample, has the lowest global C/O. The global climate may be considered as similar amongst ultra-hot Jupiters, but different to that of hot gas giants. The local weather, however, is individual for each planet since the local thermodynamic conditions, and hence the local cloud and gas properties, differ. The morning and the evening terminator of ultra-hot Jupiters will carry signatures of their strong chemical asymmetry such that ingress/egress asymmetries can be expected. An increased C/O ratio is a clear sign of cloud formation, making cloud modelling a necessity when utilizing C/O (or other mineral ratios) as tracer for planet formation. The changing geometrical extension of the atmosphere from the day to the nightside may be probed through chemically inert species like helium. Ultra-hot Jupiters are likely to develop deep atmospheric ionospheres which may impact the atmosphere dynamics through MHD processes.

description: Reference frame optimization is a generic framework to calculate a spatially-varying observer field that views an unsteady fluid flow in a reference frame that is as-steady-as-possible. In this paper, we show that the optimized vector field is objective, i.e., it is independent of the initial Euclidean transformation of the observer. To check objectivity, the optimized velocity vectors and the coordinates in which they are defined must both be connected by an Euclidean transformation. In this paper we show that a recent publication [1] applied this definition incorrectly, falsely concluding that reference frame optimizations are not objective. Further, we prove the objectivity of the variational formulation of the reference frame optimization proposed in [1], and discuss how the variational formulation relates to recent local and global optimization approaches to unsteadiness minimization.

description: Heterostructures consisting of PbZr0.2Ti0.8O3 and PbZr0.4Ti0.6O3 films grown on a SrTiO3 (100) substrate with a SrRuO3 bottom electrode were prepared by pulsed laser deposition. Using the additional interface provided by the ferroelectric bilayer structure and changing the sequence of the layers, the dislocation content and domain patterns were varied. The resulting microstructure was investigated by transmission electron microscopy. Macroscopic ferroelectric measurements have shown a large impact of the formation of dislocations and the a/c domain structure on the ferroelectric polarization and dielectric constant. A thermodynamic analysis using the LANDAU-GINZBURG-DEVONSHIRE approach that takes into account the ratio of the thicknesses of the two ferroelectric layers and electrostatic coupling is used to describe the experimental data.

description: The infiltration of a solute in a fractal porous medium is usually anomalous, but chemical reactions of the solute and that material may increase the porosity and affect the evolution of the infiltration. We study this problem in two- and three-dimensional lattices with randomly distributed porous sites at the critical percolation thresholds and with a border in contact with a reservoir of an aggressive solute. The solute infiltrates that medium by diffusion and the reactions with the impermeable sites produce new porous sites with a probability $r$, which is proportional to the ratio of reaction and diffusion rates at the scale of a lattice site. Numerical simulations for $r\ll1$ show initial subdiffusive scaling and long time Fickean scaling of the infiltrated volumes or areas, but with an intermediate regime with time increasing rates of infiltration and reaction. The anomalous exponent of the initial regime agrees with a relation previously applied to infinitely ramified fractals. We develop a scaling approach that explains the subsequent time increase of the infiltration rate, the dependence of this rate on $r$, and the crossover to the Fickean regime. The exponents of the scaling relations depend on the fractal dimensions of the critical percolation clusters and on the dimensions of random walks in those clusters. The time increase of the reaction rate is also justified by that reasoning. As $r$ decreases, there is an increase in the number of time decades of the intermediate regime, which suggests that the time increasing rates are more likely to be observed is slowly reacting systems.

The assessment of psychopathy in female offenders
Creators: name: Strachan, Catherine Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to evaluate the reliability and validity of the Psychopathy Checklist-Revised (PCL-R) for use with a female population. Seventy-five women who were either incarcerated or on probation were assessed using interview and file information. In addition, all subjects completed a battery of self-report inventories that were theoretically relevant to the PCL-R. The results strongly supported the appropriateness of the PCL-R for use with female offenders. The psychometric properties were excellent indicating a homogeneous and unidimensional scale. The factor analysis confirmed a two factor structure representing two distinct aspects of psychopathy; the personological and behavioural dimensions. The pattern of correlations obtained from the self—report inventories was highly similar to that obtained with male samples, further suggesting that the same construct is being measured in both sexes. The implications of these findings in terms of the construct of psychopathy and explanations of women’s criminality are discussed as well as future research and practical implications.

Κεντρικό ζητούμενο της έρευνας αποτελεί η εξέταση και η ερμηνεία, μέσω της ανάλυσης των ταφονομικών, οστεολογικών και βιβλιογραφικών δεδομένων, των τρόπων μεταχείρισης του νεκρού σώματος στο προανακτορικό ταφικό εθιμοτυπικό, καθώς και των συμβολικών τους προεκτάσεων. Αρχικά διερευνάται ο χαρακτήρας των αποθέσεων στα πλαίσια της εκάστοτε ταφικής παράδοσης και στη συνέχεια δίνεται ιδιαίτερη έμφαση στις ταφικές πρακτικές στα νεκροταφεία ταφικών κτιρίων μέσα από την εξέταση του προσφάτως ερευνημένου νεκροταφείου στην Κεφάλα Πετρά στη Σητεία.

Περαιτέρω, πραγματοποιείται μια προσπάθεια ανασύνθεσης των σταδίων του προανακτορικού ταφικού εθιμοτυπικού με βάση τις οστεολογικές και τις αρχαιολογικές ενδείξεις, ενώ παράλληλα συζητείται ο συμβολικός ρόλος του ατόμου και της κοινότητας στη διαμόρφωση της ιδεολογίας και της οργάνωσης των προανακτορικών κοινωνιών.
description: This paper discusses the manipulation of the dead in Crete during the 3rd and the beginnings of the 2nd millennium B.C. The main focus of the present research is to investigate, understand and interpret through the careful inspection of taphonomic, anthropological and bibliographical data, both the variety of ways in which the human body was manipulated during prepalatial funerary rituals and their symbolic connotations. As a first step to this approach the character of human bone depositions within each funerary tradition is studied, while great attention is given to the mortuary behavior in house tomb cemeteries using as a case study the Kephala Petras cemetery and in particular House Tomb 5. Later the study presents and discusses the results of the taphonomic and the macroscopic osteological analysis of the human bone assemblage of House Tomb 5 and attempts to identify possible differentiations between the funerary ritual of the Petra’s house tombs. Subsequently the present research based on archaeological and anthropological evidence tries to reconstruct the stages of the prepalatial funerary ritual and to understand the symbolic role of the individual and the community in shaping the ideology and the social structure of prepalatial communities.

description: The Chern-Simons magnetohydrodynamics (CSMHD) is introduced using a Maxwell-Chern-Simons (MCS) Lagrangian including an axion-like field $Θ$. The MCS equation of motion derived from this Lagrangian consists of a modified current, including a chiral magnetic (CM) and an anomalous Hall (AH) current, in addition to the ordinary Ohm current of resistive magnetohydrodynamics (MHD). The former consists of an axial chemical potential, which is given in terms of the temporal comoving derivative of $Θ$, and the latter arises from the spatial gradient of $Θ$. As it turns out, the existence of the axial chemical potential is a nonequilibrium effect that plays no role in the linear stability analysis, whereas the AH current arises as in the first-order linear perturbation of the thermal equilibrium. We analyze the linear stability and causality of the CSMHD in a resistive and chiral medium. We show that the Alfven modes propagating sufficiently close to the direction of the magnetic field are unstable but causal. They are also accompanied by a genuine nonhydro mode. A stable mode in a particular direction can correspond to an unstable mode propagating in the exact opposite direction. The AH instability is a manifestation of a breakdown of the parity. A numerical analysis of the phase velocity confirms these results.

description: We analyze the historical light curve of the symbiotic star YY Her, from 1890 up to December 2005. A secular declining trend is detected, at a rate of ~.01 magn in 1000 d, suggesting that the system could belong to the sub-class of symbiotic novae. Several outburst events are superposed on this slow decline. Three independent periodicities are identified in the light curve. A quasi-periodicity of 4650.7 d is detected for the outburst occurrence. We suggest that it is a signature of a solar-type magnetic dynamo cycle in the giant component. A period of 593.2 d modulates the quiescent light curve and it is identified as the binary period of the system. During outburst events the system shows a stable periodic oscillation of 551.4 d. We suggest that it is the rotation period of the giant.The secondary minima detected at some epochs of quiescence are probably due to dark spots on the surface of the rotating giant. The difference between the frequencies of these two last periods is the frequency of a tidal wave in the outer layers of the giant. A period which is a beat between the magnetic cycle and the tidal wave period is also apparent in the light curve. YY Her is a third symbiotic system exhibiting these cycles in their light curve, suggesting that a magnetic dynamo process is prevalent in the giant components of symbiotic stars, playing an important role in the outburst mechanism of some of these systems.

Probing anisotropies of gravitational-wave backgrounds with a space-based interferometer III: Reconstruction of a high-frequency skymap

description: We develop a numerical scheme to make a high-frequency skymap of gravitational-wave backgrounds (GWBs) observed via space-based interferometer. Based on the cross-correlation technique, the intensity distribution of anisotropic GWB can be directly reconstructed from the time-ordered data of cross-correlation signals, with full knowledge of detector's antenna pattern functions. We demonstrate how the planned space interferometer, LISA, can make a skymap of GWB for a specific example of anisotropic signals. At the frequency higher than the characteristic frequency $f_*=1/(2πL)$, where $L$ is the arm-length of the detector, the reconstructed skymap free from the instrumental noise potentially reaches the angular resolution up to the multipoles $\ell\sim10$. The presence of instrumental noises degrades the angular resolution. The resultant skymap has angular resolution with multipoles $\ell\leq 6\sim7$ for the anisotropic signals with signal-to-noise ratio S/N$>5$.

description: We report on the realization of a magneto-optical trap (MOT) for europium atoms using a narrow-line cooling transition with a natural linewidth of 97 kHz. Our starting point is continuous capturing and cooling of optically pumped metastable europium atoms. We have employed simultaneous MOT for the metastable and ground-state atoms. The trapped metastable atoms are successively pumped back to the ground state and then continuously loaded to the narrow-line MOT, where up to $4.7\times10^7$ atoms are captured. A spin-polarized sample at a temperature of $6\,\mathrm{μK}$ and with a peak number density of $2.2\times10^{11}\,\mathrm{cm^{-3}}$ is obtained through the compression process, resulting in a phase space density of $3\times10^{-5}$.

Warm-hot intergalactic medium contribution to baryonic matter

Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Hydrodynamical simulations indicate that substantial fraction of baryons in the Universe remains in a diffuse component - Warm-Hot Intergalactic Medium (WHIM). To determine physical properties (spatial distribution, temperature and density) of the WHIM, spatial structure of the soft extended X-ray emission surrounding field galaxies is carefully investigated using the XMM-Newton EPIC/MOS observations. Angular correlations between the galaxy distribution and the soft X-ray background extending over several arcmin are determined. The correlations at large scales result from the clustering of galaxies. At small scales (below ~2 arcmin) the excess of the soft flux is interpreted as the genuine emission from halos of the WHIM surrounding individual galaxies. Bulk parameters of the average WHIM halos associated with galaxies in the sample are estimated. Typical halo has a characteristic radius of ~0.3 Mpc and a mass of 4 - 7 x 10^11 M_sun. The average density of the WHIM in the local universe amounts to 7 - 11 x 10^{-32} g cm^{-3} (Omega_WHIM = 0.7 - 1.2 %). Observations of the X-ray WHIM emission are in good agreement with the numerical simulations, but accuracy of the observational material is insufficient to constrain the theory of WHIM. A series of deep observations of a moderately numerous sample of low redshift galaxies with high resolution instruments of Chandra would significantly improve our estimates of the WHIM parameters.

description: The bulk band topology of symmetry invariant adiabatic systems in the thermodynamic limit are considered to be determined by the hopping energy. In this work, we present that in closed classical systems, due to generalized chiral symmetry broken, the on-site energy cannot always be regarded as identical and can crucially impact the topological properties of the systems. Based on a finite one-dimensional chain, we demonstrate that the non-equivalent on-site energy of bulk lattices affects the topological phases of the bands, and the on-site energy of end lattices affects the existence of the topological states. Along these lines, the correspondence with generalized chiral symmetry in acoustic system is rigorously proposed. Our work provides a new degree of freedom for topological classical systems, and can be generalized to higher-dimensions and non-Hermitian conditions.

description: In stellar interferometry, image quality improves significantly with the inclusion of more telescopes and the use of phase closure. We demonstrate, using first coherent and then partially coherent white light, a compact and efficient pair-wise combination of twelve or more beams. The input beams are lined up and spread through a cylindrical lens into a comb of parallel ellipses, which interferes with a perpendicular copy of itself to form a matrix of interferograms between all pairs. The diagonal elements show interference of each beam with itself, for in-tensity calibration. The measured white-light visibilities were high and stable.

description: Millisecond spinning, low magnetic field neutron stars are believed to attain their fast rotation in a 0.1-1 Gyr-long phase during which they accrete matter endowed with angular momentum from a low-mass companion star. Despite extensive searches, coherent periodicities originating from accreting neutron star magnetospheres have been detected only at X-ray energies and in ~10% of the presently known systems. Here we report the detection of optical and ultraviolet coherent pulsations at the X-ray period of the transient low mass X-ray binary system SAX J1808.4-3658, during an accretion outburst that occurred in August 2019. At the time of the observations, the pulsar was surrounded by an accretion disc, displayed X-ray pulsations and its luminosity was consistent with magnetically funneled accretion onto the neutron star. Current accretion models fail to account for the luminosity of both optical and ultraviolet pulsations; these are instead more likely driven by synchro-curvature radiation in the pulsar magnetosphere or just outside of it. This interpretation would imply that particle acceleration can take place even when mass accretion is going on, and opens up new perspectives in the study of coherent optical/UV pulsations from fast spinning accreting neutron stars in low-mass X-ray binary systems.

Coupled channel calculations have been performed to understand the one neutron stripping and pickup cross sections along with the breakup in the $^{7}$Li+$^{124}$Sn system. The systematics of one and two neutron striping and pickup cross sections with $^7$Li projectile on several targets show an approximate universal behaviour that have been explained by a simple model. Complete reaction mechanism have been studied by comparing the reaction cross sections with cumulative cross sections of total fusion and one neutron transfer.

description: Nell’inverno del 1300-1301, l’Occidente latino venne a conoscenza che Maḥmūd Ghāzān īl-khān di Persia aveva conquistato la Terra Santa, occupando la Città Santa. La notizia generò un fervore generale in tutta Europa e un gruppo di nobildonne di Genova, decise di unirsi alla spedizione mongola, organizzando esse stesse una crociata sotto la guida di Benedetto Zaccaria e chiedendo l’autorizzazione a Bonifacio VIII. Il papa, in un primo momento accolse la proposta con grande entusiasmo ma poi ne prese le distanze. Il saggio formula alcune considerazioni sui potenziali interessi pastorali e missionari che Bonifacio VIII avrebbe voluto perseguire appoggiando l’iniziativa crociata delle nobildonne genovesi.


In the winter of 1300-1301, an exciting news spread across the Latin West: Maḥmūd Ghāzān īl-khān of Persia had conquered the Holy Land and he occupied the Holy City. This event sparked great fervour in all Europe and a group of genoese women decided to go to in the Levant to join mongol expedition. Before departing, ladies asked permission from Boniface VIII, who initially accepted the genoese proposal, but later he abandoned it. This essay focuses especially about pastoral and missionary interest of Pope in the Mongol East. The most question are: what was the missionary projects of Pope? How is this issue connected whit the Genoese expedition?

description: To evaluate and compare the effectiveness and quality of standard face-to-face and teleaudiology hearing aid fitting follow-up consultations and blended services for adult hearing aid users. Fifty-six participants were randomly allocated to two equal groups, with equal numbers of new and experienced users. One standard and one teleaudiology follow-up consultation were delivered by an audiologist, the latter assisted by a facilitator. The order was reversed for the second group. Outcome measurement tools were applied to assess aspects of participants’ communication, fitting (physical, sensorial), quality of life, and service. Cross-sectional and longitudinal outcomes were analysed. Most participants presented with moderate, sloping, and symmetrical sensorineural hearing loss. The duration of teleaudiology (42.96 ± 2.73 min) was equivalent to face-to-face consultations (41.25 ± 2.61 min). All modes of service delivery significantly improved outcomes for communication, fitting, and quality of life (p > 0.05). Satisfaction for both consultation modes was high, although significantly greater with standard consultations. The mode and order of delivery of the consultations did not influence the outcomes. Teleaudiology hearing aid follow-up consultations can deliver significant improvements, and do not differ from standard consultations. Blended services also deliver significant improvements. Satisfaction can be negatively impacted by technical or human-related issues.

description: We report on the first steady-state simulations of strong plasma shocks with fully kinetic ions and electrons, independently confirmed by two fully kinetic codes (an Eulerian continuum and a Lagrangian particle-in-cell). While kinetic electrons do not fundamentally change the shock structure as compared with fluid electrons, we find an appreciable rearrangement of the preheat layer, associated with nonlocal electron heat transport effects. The electron heat flux profile qualitatively agrees between kinetic and fluid electron models, suggesting a certain level of "stiffness", though substantial nonlocality is observed in the kinetic heat flux. We also find good agreement with nonlocal electron heat-flux closures proposed in the literature. Finally, in contrast to the classical hydrodynamic picture, we find a significant collapse in the "precursor" electric-field shock at the preheat layer edge, which correlates with the electron-temperature gradient relaxation.

description: Il contributo si pone principalmente due obiettivi: l’assegnazione della paternità della cronaca linguistica Noterelle di lingua, comparsa su La Stampa tra il 1947 e il 1953, a Euclide Carlo Milano; la delineazione dei confini temporali entro i quali collocare la pubblicazione della rubrica, quindi la sua retrodatazione dal 1949 al 1947. Nella seconda parte dell’articolo si tracciano i contorni della vita e dell’impegno lavorativo e culturale di Milano, intellettuale poliedrico nato nel 1880, cercando di evidenziare il suo contributo culturale e sociale nonostante le sfide politiche del suo tempo alle quali ha preso parte in prima persona.


The contribution has two main objectives: to attribute the authorship of the linguistic column Noterelle di lingua, which appeared in La Stampa between 1947 and 1953, to Euclide Carlo Milano; to delineate the temporal boundaries within which to place the publication of the column, thus backdating it from 1949 to 1947. In the second part of the article, the outlines of the life, work and cultural commitment of Milan, a multifaceted intellectual born in 1880, are traced, attempting to highlight his cultural and social contribution despite the political challenges of his time in which he personally took part.

Science Policy

description: The purpose of this scoping review was two-fold, (1) to provide information about the characteristics, type of service delivery, participant information and outcomes related to tele-audiology in clinical popluations, and (2) to describe documented facilitators and barriers to tele-audiology delivery from the perspectives of practitioners and service recipients. Knowledge of these findings can assist audiologists in considering remote service delivery options for their practices. A scoping review was conducted in November 2019 to identify English-language peer-reviewed journal articles published from 1 January 2010 to 30 October 2019 related to remote clinical service delivery in audiology. Thirty-six published research articles were included. Research studies were classified into four broad areas with some articles including more than one area within the scope of their article: Screening (n = 5), Diagnostic (n = 5), Intervention (n = 18), and Perspectives (n = 22). Hearing healthcare service delivery is expanding with the changing technological landscape, providing greater opportunities and flexibility for audiologists and patients. There are clear opportunities for interdisciplinary collaboration and for collaboration with on-site local facilitators. Local facilitators, with training, can assist in connecting individuals to follow-up care, provide educational support, and needed hands-on assistance for specialised testing.
Accurate simulations of the dynamical bar-mode instability in full General Relativity

description: We present accurate simulations of the dynamical bar-mode instability in full General Relativity focussing on two aspects which have not been investigated in detail in the past. Namely, on the persistence of the bar deformation once the instability has reached its saturation and on the precise determination of the threshold for the onset of the instability in terms of the parameter $β={T}/{|W|}$. We find that generic nonlinear mode-coupling effects appear during the development of the instability and these can severely limit the persistence of the bar deformation and eventually suppress the instability. In addition, we observe the dynamics of the instability to be strongly influenced by the value $β$ and on its separation from the critical value $β_c$ marking the onset of the instability. We discuss the impact these results have on the detection of gravitational waves from this process and provide evidence that the classical perturbative analysis of the bar-mode instability for Newtonian and incompressible Maclaurin spheroids remains qualitatively valid and accurate also in full General Relativity.

SULLE ORIGINI DELLA CRITICA E CLINICA DI DELEUZE: LE PRIME OPERE DEGLI ANNI SESSANTA E LE 'BOZZE' DI DIFFERENZA E RIPETIZIONE
Creators: name: Fleres, Daniele
Publisher: name: PELORO
Year: 2023

description: L’implicarsi di critica e clinica è una dei tratti più peculiari della filosofia di Deleuze. Attraverso le prime opere degli anni Sessanta e le bozze coeve di Differenza e ripetizione, si vuole rilevare come questa implicazione sia all’origine della filosofia deleuziana e ne contrassegni la postura teorico-pratica. Coinvolgendo le letture deleuziane di Nietzsche, Kant, Proust e Masoch, si scorge come l’istituzione della critica sia funzionale a una riflessione clinica sulla vita, tratto che le bozze di Differenza e ripetizione modellano nelle nuove creazioni concettuali dell’immagine del pensiero e di un inconscio differenziale.


Deleuze’s clinic critic is one of the most peculiar expression of his philosophy. Through the 1960s first works and the contemporary Difference and Repetition’s drafts we can focus the role of the critic and the clinic at the origin of the theoretical-practical constitution of Deleuzian philosophy. The works on Nietzsche, Kant, Proust and Masoch point out the clinical reflexion on life in the critic’s foundation. On this basis, Deleuze proposes a new conception of the Image of thought and differential subconscious in Difference and Repetition’s drafts.

description: We experimentally study the tunability of the cooperativity in coupled spin--cavity systems by changing the magnetic state of the spin system via an external control parameter. As model system, we use the skyrmion host material Cu$_2$OSeO$_3$ coupled to a microwave cavity resonator. In the different magnetic phases we measure a dispersive coupling between the resonator and the magnon modes and model our results by using the input--output formalism. Our results show a strong tunability of the normalized coupling rate by magnetic field, allowing us to change the magnon--photon cooperativity from 1 to 60 at the phase boundaries of the skyrmion lattice state.

description: Recent findings of superconductors that simultaneously exhibit multiple spontaneously broken symmetries, such as ferromagnetic order or lack of an inversion center and even combinations of such broken symmetries, have led to much theoretical and experimental research. We consider quantum transport in a junction consisting of a ferromagnetic metal and a non-unitary ferromagnetic superconductor. It is shown that the conductance spectra provides detailed information about the superconducting gaps, and is thus helpful in determining the pairing symmetry of the Cooper pairs in ferromagnetic superconductor.

description: We study analytically the two dimensional deformed bosonic oscillator equations for charged particles (both spin 0 and spin 1 particles) subject to the effect of a uniform magnetic field. We consider the presence of a minimal uncertainty in momentum caused by the Anti-deSitter model and we use the Nikiforov-Uvarov method to solve the system. The exact energy eigenvalues and the corresponding wave functions are analytically obtained for both Klein-Gordon and scalar Duffin-Kemmer-Petiau cases. For spin 1 DKP case, we deduce the behaviour of the DKP equation and write the non-relativistic energies where we show the fundamental role of the spin in this case. Finally, we study the thermodynamic properties of the system.

description: Applying domain decomposition to the lattice Dirac operator and the associated quark propagator, we arrive at expressions which, with the proper insertion of random sources therein, can provide improvement to the estimation of the propagator. Schemes are presented for both open and closed (or loop) propagators. In the end, our technique for improving open contributions is similar to the ``maximal variance reduction'' approach of Michael and Peisa, but contains the advantage, especially for improved actions, of dealing directly with the Dirac operator. Using these improved open propagators for the Chirally Improved operator, we present preliminary results for the static-light meson spectrum. The improvement of closed propagators is modest: on some configurations there are signs of significant noise reduction of disconnected correlators; on others, the improvement amounts to a smoothening of the same correlators.

description: Excess emission from a point-like source coincident with the central star of the Helix Nebula is detected with Spitzer at 8, 24, and 70 um. At 24 um, the central source is superposed on an extended diffuse emission region. While the [OIV] 25.89 um line contributes to the diffuse emission, a 10-35 um spectrum of the central source shows a strong thermal continuum. The excess emission from the star most likely originates from a dust disk with blackbody temperatures of 90--130 K. Assuming a simple optically thin debris disk model, the dust is distributed in a ring between ~35 and ~150 AU from the central star, possibly arising from collisions of Kuiper-Belt-like Objects or the break-up of comets from an Oort-like cloud that have survived from the post-main-sequence evolution of the central star.

description: The low-lying n(=3,4,5)d $^2D_{5/2}$ states alkaline earth ions are of vital importance in a number of different physical applications. The hyperfine structure constants of these states are characterized by unusually strong electron correlation effects. Relativistic coupled-cluster theory has been employed to carry out {\it ab initio} calculations of these constants. The role of the all order core-polarization effects was found to be decisive in obtaining good agreement of the results of our calculations with accurate measurements. The present work is an apt demonstration of the power of the coupled-cluster method to cope with strongly interacting configurations.
