description: Organ transplantation in presensitized recipients continues to be contraindicated for heart and kidney recipients due to the risk of hyperacute rejection, which has no known treatment at this time. We tested whether donor serum, which contains soluble MHC class I antigen, is able to neutralize the effect of anti-donor antibody in the recipient and prevent hyperacute or accelerated rejection. A rat model of passive immunization was used to test the role of anti-donor antibody in hyperacute rejection. Seven of 10 recipients of hyperimmune serum (HyS), derived from Lewis rats (RT1l) following 3 ACI (RT1a) skin grafts, developed hyperacute or accelerated rejection. Intravenous injection of ACI serum prior to the HyS administration prevented hyperacute rejection in all recipients tested. When third-party (Wistar-Furth, RT1u) serum was given to Lewis rats injected with HyS, hyperacute rejection was not abrogated. When examining the mechanism of this effect, a simple antibody blocking phenomenon was found to be unlikely since flow cytometry analysis showed that ACI serum needed to be present at > or = 256-fold excess compared to HyS to block anti-ACI antibody binding to RT1.Aa+cells by 50%. We tested whether the RT1.Aa class I antigen in ACI serum had other biologic properties that resulted in the prolonged graft survival. However, removal of RT1.Aa antigen from ACI serum prior to use in the passive transfer model did not abrogate the graft prolongation observed previously. These data suggest that components of donor serum other than MHC class I antigen may be useful for preventing the antibody-mediated component of hyperacute rejection.

description: We discuss the magnon spectrum of an antiferromagnet (AF) in a magnetic field $h$ consisting of two interpenetrating AF sublattices coupled by the exchange interaction at T=0. One-ion easy-plane anisotropy is also taken into account. We calculate using the 1/S expansion the gap in the spectrum which is a manifestation of the order-by-disorder effect in this system and the optical magnon mode splitting. Both of these phenomena originate from the inter-sublattice interaction. We calculate also the gap value at $h\approx h_c$ in the leading order of the small parameter $(h_c-h)/h_c$ using the magnon Bose-Einstein condensation treatment, where $h_c$ is the saturation field. By comparing results obtained within these two approaches we conclude that the 1/S expansion gives a qualitatively correct result at $h\sim h_c$ even at large one-ion anisotropy but it overestimates the gap value. The application is discussed of these results to the actively studied AF of the considered type $\rm NiCl_2$-$\rm 4SC(NH_2)_2$ (DTN).

description: Ο Έλληνας νομοθέτης από πολύ νωρίς αντιλήφθηκε την αναγκαιότητα ενασχόλησής του με εγκληματικές ενέργειες που έχουν ως κύριο αντικείμενο ναρκωτικές ουσίες. Εξ αυτού του λόγου, αρχικά προχώρησε στην ποινικοποίηση των ενεργειών αυτών θεσπίζοντας για πρώτη φορά το Ν. 1729/1987, ο οποίος αποτέλεσε το θεμέλιο της ελληνικής νομοθεσίας περί εξαρτησιογόνων ουσιών. Έκτοτε, όμως, μεσολάβησε ένα πολύ μεγάλο χρονικό διάστημα, κατά τη διάρκεια του οποίου κρίθηκε απαραίτητη η προσαρμογή της νομοθεσίας στις ολοένα και περισσότερες απαιτήσεις για την αποτελεσματικότερη αντιμετώπιση αυτού του ιδιαίτερου φαινόμενου που δε σταματά να απασχολεί την κοινωνία μας. Στην παρούσα μεταπτυχιακή μελέτη πρόκειται να γίνει παρουσίαση και ανάλυση των επιμέρους διατάξεων που αναφέρονται στην ποινική αντιμετώπιση των τελούντων αδικημάτων σχετικών με τα ναρκωτικά. Συγκεκριμένα, θα ασχοληθούμε με το ζήτημα της ποινικής μεταχείρισης των ανήλικων, που έχουν τελέσει κάποιο αδίκημα του νόμου περί ναρκωτικών ουσιών, εξετάζοντας τις διάφορες σχετικές προβλέψεις, σύμφωνα με τον ισχύοντα Ποινικό Κώδικα, όπως αυτός διαμορφώθηκε με το νέο νόμο 4619/2019, καθώς και με το νόμο περί εξαρτησιογόνων ουσιών (Ν. 4139/2013).
description: The Greek legislator realized from a very early “spot” the necessity of dealing with criminal acts that have as their main object drugs. For this reason, initially he proceeded to criminalize these actions by enacting for the first time Law 1729/1987, which was the foundation of the Greek legislation on addictive substances. Since then, however, there has been a very long period of time during which it was deemed necessary to adapt the legislation to the increasing demands in order to deal more effectively with this particular phenomenon that does not cease to concern our society. In the present postgraduate study, the individual provisions that refer to the criminal treatment of drug-related crimes will be presented and analyzed. Specifically, we will talk about the issue of criminal treatment of young people who have committed a crime under the law on drugs, testing the various relevant provisions, according to the current Penal Code, as formulated by the new law 4619/2019, as well with the law on addictive substances (Law 4139/2013).

description: Kinetic Alfven wave turbulence in solar wind is considered and it is shown that non-Maxwellian electron distribution function has a significant effect on the dynamics of the solar wind plasmas. Linear Landau damping leads to the formation of a plateau in the parallel electron distribution function which diminishes the Landau damping rate significantly. Nonlinear scattering of waves by plasma particles is generalized to short wavelengths and it is found that for the solar wind parameters this scattering is the dominant process as compared to three wave decay and coalescence in the wave vector range . Incorporation of these effects lead to the steepening of the wave spectrum between the inertial and the dissipation ranges with a spectral index between 2 and 3. This region can be labeled as the scattering range. Such steepening has been observed in the solar wind plasmas.

description: We show that the space symmetry of bilayer systems, coupled by both tunneling and Coulomb interaction, has fundamental influences on the collective charge-density excitations. In the general case of two-subband occupation, three modes with one intersubband and two (optical and acoustic, respectively) intrasubband plasmons are calculated. By breaking the space symmetry, these modes are found to be mixed, giving rise to an anticrossing behavior between the intersubband and optical intrasubband plasmons. For the asymmetric case, the acoustic intrasubband plasmon is not Landau damped in the long-wavelength limit.

description: We analyze the masses and spatial distributions of fourteen young stellar groups in Taurus, Lupus3, ChaI, and IC348. These nearby groups, which typically contain 20 to 40 members, have membership catalogs complete to ~0.02 M_sun, and are sufficiently young that their locations should be similar to where they formed. These groups show five properties seen in clusters having many more stars and much greater surface density of stars: (1) a broad range of masses, (2) a concentration of the most massive star towards the centre of the group, (3) an association of the most massive star with a high surface density of lower-mass stars, (4) a correlation of the mass of the most massive star with the total mass of the group, and (5) the distribution of a large fraction of the mass in a small fraction of the stars.

Physical activity in fibrotic interstitial lung disease
Creators: name: Hur, Seo Am
Publisher: name: University of British Columbia
Year: 2018

description: Fibrotic interstitial lung diseases (ILDs) are characterized by inflammation and fibrosis of the pulmonary parenchyma. In addition to the primary symptoms of dyspnea and cough, many patients with fibrotic ILD experience extrapulmonary deficits that can interfere with their ability to stay active. This is a concern as the maintenance of physical activity plays an important part in independence and prevention of deconditioning in patients with fibrotic ILD. However, the impact of common extrapulmonary deficits on daily physical activity of these patients is not known. Accordingly, in chapter 2, we examined the impact of depression, anxiety, poor sleep quality, and pain on daily physical activity in a cohort of 111 patients with fibrotic ILD. Extrapulmonary deficits were assessed using the Hospital Anxiety and Depression Scale, the Pittsburgh Sleep Quality Index, and the Brief Pain Inventory short form. Patients' physical activity was monitored for seven consecutive days using waist and wrist tri-axial accelerometers, in addition to the self-reported International Physical Activity Questionnaire long form (IPAQ-LF). Although depression and pain were moderately associated with lower step count on unadjusted analysis, extrapulmonary deficits did not independently predict lower physical activity when adjusting for basic demographics and ILD severity. However, we identified higher pain severity to be an independent predictor of lower step count using a multivariable stepwise approach. This finding suggests that pain may be a potential area that could be targeted by interventions to help patients maintain physical activity. In chapter 3, we examined the validity of the IPAQ-LF and estimated the minimally important difference (MID) for moderate-to-vigorous physical activity (MVPA) in patients with fibrotic ILD. We found the IPAQ-LF to have acceptable validity based on its measurements having moderate-to-strong correlations with corresponding waist accelerometer data and relevant clinical outcomes. The MID for weekly MVPA was estimated to be less than 60 minutes/week using the anchor-based approach. This indicates that adding only 60 minutes of MVPA per week is a realistic goal that brings meaningful benefits to patients with fibrotic ILD and provides a goal threshold for future clinical trials.

description: One RP-HPLC and two chemometric assisted UV spectrophotometric methods were developed and validated for the simultaneous in vitro analysis of Atrovastatin calcium (ATV), Ezetimibe (EZET) and Fenofibrate (FEN) in their pharmaceutical preparation and ternary mixtures. The chromatographic separation was achieved on a reversed-phase, Hypersil BDS C8 column (250X4.6 mm i.d, 5 particle size) with a mobile phase consisting of methanol and 0.05M phosphate buffer (pH-6.3 adjusted with sodium hydroxide) in the ratio of (85:15)% v/v. The total run time was 7 min. Quantitation was achieved with UV detection at 248nm based on peak area. Linearity was observed over concentration range of 5 - 12μg mL-1 for ATV and EZET and 80 - 192 μg mL-1 for FEN. The two chemometric methods applied were inverse least square (ILS) and classical least square (CLS). These approaches were successfully applied to quantify each drug in their mixture using the information included in the UV absorption spectra of appropriate solutions in the wavelength range 220-310nm with the intervals of 5nm (Δλ = 5nm) at 19 wavelength points. For the chemometric calibration, 18 ternary solutions were prepared as training set and 10 ternary solutions were prepared as validation set. The developed methods were successfully applied for laboratory prepared mixtures as well as commercial tablet formulation for ATV, EZET and FEN concentration. The results obtained for pharmaceutical formulation by ILS and CLS methods were compared with isocratic HPLC method and a good agreement was found.

description: Many stars exhibit stellar pulsations, favoring them for asteroseismic analyses. Interpreting the oscillations requires some knowledge of the oscillation mode geometry (spherical degree, radial and azimuthal orders). The delta Scuti stars (1.5 - 2.5 M_sol) often show just one or few pulsation frequencies. Although this may promise a successful seismological analysis, we may not know enough about either the mode or the star to use the oscillation frequency to improve the determination of the stellar model, or probe the star's structure. For the observed frequencies to be used successfully as seismic probes of these objects, we need to concentrate on stars for which we can reduce the number of free parameters in the problem, such as binary systems or open clusters. We investigate how much our understanding of a delta Scuti star is improved when it is in a detached eclipsing binary system instead of being a single field star. We use singular value decomposition to explore the precision we expect in stellar parameters (mass, age and chemical composition) for both cases. We examine how the parameter uncertainties propagate to the luminosity - effective temperature diagram and determine when the effort of obtaining a new measurement is justified. We show that for the single star, a correct identification of the oscillation mode is necessary to produce strong constraints on the stellar model properties, while for the binary system the observations without the pulsation mode provide the same or better constraints on the stellar parameters. In the latter case, ...

Magnetoconductance of the Corbino disk in graphene
Creators: name: Rycerz, Adam
Publisher: name: Universität Regensburg
Year: 2010
Subjects: subject: 530 Physik

description: Electron transport through the Corbino disk in graphene is studied in the presence of uniform magnetic fields. At the Dirac point, we observe conductance oscillations with the flux piercing the disk area Φd, characterized by the period Φ0=2(h/e)ln(Ro/Ri), where Ro(Ri) is the outer (inner) disk radius. The oscillations magnitude increase with the radii ratio and exceed 10% of the average conductance for Ro/Ri≥5 in the case of the normal Corbino setup or for Ro/Ri≥2.2 in the case of the Andreev-Corbino setup. At a finite but weak doping, the oscillations still appear in a limited range of |Φd|≤Φdmax, away from which the conductance is strongly suppressed. At large dopings and weak fields we identify the crossover to a normal ballistic transport regime.

description: The goal of task 6.3 “Empowering Users: Training Materials and Online Learning Paths” was primarily to provide an overview and to collect existing training materials in the area of Social Sciences and Humanities (SSH), as well as to support the creation of training materials within the SSHOC project. The task of inventorising was summarized in a previous deliverable D6.7 Inventory of training materials1. An update of the state of affairs is given in section 2 Landscape which details how the initial inventory has been reused for train-the-trainer purposes and in section 3 Metadata that depicts how SSHOC training materials metadata have been developed in relation to other existing schemas. Another part of the work of task 6.3 concentrated on devising a new technical system, which supports the creation of new training materials as described in section 4. Finally, with respect to the sustainability and longevity of the efforts, the task operated in close coordination with the WP7, developing the SSH Open Marketplace, a discovery platform for resources relevant for SSH research, including training material. Details of this collaboration are described in section 5.

description: Electronic excitations in AlxGa1-xAs-GaAs quantum wires and quantum dots have been investigated by means of resonant inelastic light scattering. At low frequencies, we find quasi-one-dimensional and quasi-zero-dimensional confined plasmons. Interestingly, we observe, at higher frequencies, not only the original two-dimensional (2D) intersubband excitations, but additional modes ωk in polarized scattering geometry. The experimental finding is that the frequencies of these modes obey the relation ωk2≊ω2D2+ω 1D/0D2, where ω2D is the frequency of the vertical intersubband charge-density excitation. ω1D is a lateral quasi-one-dimensional confined plasmon frequency in wires and ω0D is the frequency of a quasi-zero-dimensional confined plasmon in dots. This relation shows that the additional modes are collective charge-density excitations, which occur due to a coupling of lateral and vertical electron motion.

description: A hypothetical layered oxide La_2NiMO_6 where NiO_2 and MO_2 planes alternate along the c-axis of ABO_3 perovskite lattice is considered theoretically. Here, M denotes a trivalent cation Al, Ga,... such that MO_2 planes are insulating and suppress the c-axis charge transfer. We predict that correlated e_g electrons in the NiO_2 planes develop a planar x^2-y^2 orbital order driven by the reduced dimensionality and further supported by epitaxial strain from the substrate. Low energy electronic states can be mapped to a single-band t-t'-J model, suggesting favorable conditions for high-T_c superconductivity.

description: We present an investigation of the dynamics of the inter-Landau-level (LL) excitations of a two-dimensional electron gas (2DEG) in large magnetic fields using coherent time-resolved nonlinear spectroscopy. The results are compared directly with measurements on undoped quantum wells. We observe time-dependent Coulomb coupling between the LL's induced by the 2DEG that induces a large transfer of oscillator strength to the lowest LL. The time dependence of the nonlinear response reveals non-Markovian and memory effects of the photoexcited system that cannot be understood in terms of the random phase approximation. We introduce a theoretical approach that treats the interactions of the magnetoexcitons with the 2DEG excitations and qualitatively accounts for the most salient experimental results in terms of shake-up of the 2DEG.

description: High spatial and sensitivity images of the Luminous Blue Variable IRAS 18576+0341 were obtained using the mid infrared imager VISIR at the Very Large Telescope and the Very Large Array interferometer. The resulting mid-infrared continuum maps show a similar clumpy and approximately circular symmetric nebula, which contrasts sharply with the asymmetry that characterizes the ionized component of the envelope, as evidenced from the radio and [Ne II] line images obtained with comparable spatial resolution. In particular, there is excellent overall agreement between the 12.8 micron map and the radio images, consistent with free-free emission from circumstellar ionized material surrounding a central stellar wind. The color temperature and optical depth maps obtained from mid-infrared images show only slight fluctuations, suggesting quite uniform dust characteristics over the dust shell. We explore various possibilities to understand the cause of the different morphology of the dusty and gaseous component of the circumstellar envelope which are compatible with the observations.

description: We have investigated experimentally and theoretically electronic Raman excitations in GaAs-AlxGa1-xAs quantum wires in magnetic fields. In both the experiments and the calculations we find strong anticrossings of the observed confined magnetoplasmon modes in the vicinity of 2ωc, where ωc is the cyclotron-resonance frequency. The observed splittings and anticrossings arise from internal Coulomb interaction in the one-dimensional electron systems and is found to depend sensitively not only on the wave vector but also on the shape of the confining potential and the mode index of the confined plasmon mode.

description: We correlate simultaneously recorded magnetotransport and spatially resolved magneto optical Kerr effect (MOKE) data in Co2FeAl Heusler compound thin films micropatterned into Hall bars. Room temperature MOKE images reveal the nucleation and propagation of domains in an externally applied magnetic field and are used to extract a macrospin corresponding to the mean magnetization direction in the Hall bar. The anisotropic magnetoresistance calculated using this macrospin is in excellent agreement with magnetoresistance measurements. This suggests that the magnetotransport in Heusler compounds can be adequately simulated using simple macrospin models, while the magnetoresistance contribution due to domain walls is of negligible importance.

description: There has been limited evidence for the association between socioeconomic status (SES) and arterial stiffness. This study was performed to investigate the association between household income and brachial pulse pressure (PP) in the general Korean population. This study was based on data acquired in the 2018 Korea National Health and Nutrition Examination Survey (2018 KNHANES). A total of 13004 subjects at the age of 20 years or older analysed. The information on monthly household income was obtained through the questionnaire, and was stratified into 5 groups for each quintile. Brachial blood pressure (BP) was measured 3 times, and the average of the second and third measured BPs were used. PP was calculated as the difference between systolic and diastolic BPs. A lower household income was associated with a higher prevalence of cardiovascular risk factors. As household income increased, PP decreased proportionally (p β = −.125, p vs. the highest household income; odds ratio, 0.48; 95% confidence interval, .41–.55; p Low household income was associated with higher PP. This provides additional evidence for the association between low SES and high arterial stiffness.

Evaluating and enhancing the taxonomic resolution of shark and ray (Subclass Elasmobranchii) catch statistics in the Mediterranean and Black Seas (1950-2014)
Creators: name: Cashion, Madeline Self
Publisher: name: University of British Columbia
Year: 2018

description: To sustainably manage fisheries, the stock biology, ecology, and its past and present human exploitation must be known. To monitor fisheries, the Food and Agriculture Organization of the United Nations began collecting and harmonizing country catch reports in the late 1940s. In 1950, it issued its first global annual catch statistics, which have continued until the present. This official reported catch has been shown to vastly underrepresent the entirety of the world's catch. The small-scale fisheries sectors (i.e., artisanal, subsistence, and recreational) are largely unreported, in addition to incidental catches of non-target species, much of which is discarded. The latter component of the catch is often comprised of species that are more biologically vulnerable to overfishing than target species. Sharks and rays (subclass Elasmobranchii) are one such group of species. One in four elasmobranch species are estimated to be threatened with extinction, primarily as a result of overfishing. Unfortunately, elasmobranch catch data are notoriously underreported and imprecise. This thesis sought to elucidate the elasmobranch catches of the Mediterranean and Black Seas, where over half of shark and ray species are threatened with extinction but data deficiency and ambiguity consistently limit conservation action. A Taxonomic Resolution Index (TRI) was calculated for the catches of 24 countries over 65 years (1950-2014) to evaluate the quality of catch reporting over time. The TRI revealed that less than a quarter of commercial elasmobranch taxa are represented in Mediterranean and Black Seas catch data, and reporting quality has hardly improved. While many countries have improved their reporting since the 1950s, the original leaders (e.g., Malta and Georgia) have seen their position worsening over time. The species composition of reconstructed historical elasmobranch catch was also investigated. The fishery characteristics of species-specific catches were modeled and used to estimate unknown species-specific proportions within aggregated catch categories (e.g., "sharks and rays"). Over half a million tonnes of species-specific catch was disaggregated, increasing the species-specific proportion of reported catches by over 10%. These results, combined with a literature review, imply weak implementation and enforcement of existing protective regulations, despite precipitous declines of elasmobranchs in the Mediterranean and Black Seas.

description: Site measurements were collected at Mount John University Observatory in 2005 and 2007 using a purpose-built scintillation detection and ranging system. $C_n^2(h)$ profiling indicates a weak layer located at 12 - 14 km above sea level and strong low altitude turbulence extending up to 5 km. During calm weather conditions, an additional layer was detected at 6 - 8 km above sea level. $V(h)$ profiling suggests that tropopause layer velocities are nominally 12 - 30 m/s, and near-ground velocities range between 2 -- 20 m/s, dependent on weather. Little seasonal variation was detected in either $C_n^2(h)$ and $V(h)$ profiles. The average coherence length, $r_0$, was found to be $7 \pm 1$ cm for the full profile at a wavelength of 589 nm. The average isoplanatic angle, $θ_0$, was $1.0 \pm 0.1$ arcsec. The mean turbulence altitude, $\bar{h_0}$, was found to be $2.0\pm0.7$ km above sea level. No average in the Greenwood frequency, $f_G$, could be established due to the gaps present in the \vw\s profiles obtained. A modified Hufnagel-Valley model was developed to describe the $C_n^2(h)$ profiles at Mount John, which estimates $r_0$ at 6 cm and $θ_0$ at 0.9 arcsec. A series of $V(h)$ models were developed, based on the Greenwood wind model with an additional peak located at low altitudes. Using the $C_n^2(h)$ model and the suggested $V(h)$ model for moderate ground wind speeds, $f_G$ is estimated at 79 Hz.

description: By means of resonance Raman spectroscopy we have observed a characteristic shift of hole-intersubband transitions with excitation energy in p-doped GaAs/AlxGa1-xAs quantum-well structures. As possible reasons for the shift, the nonparabolicity of the valence subbands as well as fluctuations of the well width are discussed. Both contributions can be separated experimentally by application of an external magnetic field, which quantizes the in-plane motion of the carriers. For our samples, we can show that the shifts observed for B=0 T are mainly caused by subband nonparabolicity. This interpretation is confirmed by a comparison with results of a simulation of single-particle Raman spectra based on a subband calculation with Luttinger’s 4×4 Hamiltonian. Corresponding shifts are observed both in depolarized and polarized spectra.
On the rotation period of the O giant xi Persei: a weakly magnetic candidate star

description: The recurring pattern on a rotational timescale of discrete absorption components (DACs) in wind-line profiles in OB stars is generally considered to be cyclical (like sunspots), rather than periodic. This is in accordance with the lack of evidence for a permanent magnetic field for most of these stars. We report the discovery of a unique periodicity in the O7.5 giant \(\xi\) Per of 2.04058(3) d in the low-velocity wind region very close to the star, as probed by the NIV 1718 line in 307 IUE and 11 STIS spectra covering 33 years. We also find this period in the Si IV 1402 line of the IUE spectra, but could not confirm this for STIS, probably because the average Si IV profile of the IUE and STIS spectra differ, which may indicate an additional long term effect, not reported before. The signal is sinusoidal which we interpret as due to the effect of rotation. In data folded with this period, the DAC pattern holds for these 33 years, i.e. ~6000 rotations. We predict that \(\xi\) Per has a corotating weak magnetic dipole field. The current upper limit on the polar value is 59 G. The sinusoidal behavior implies that only one magnetic pole is visible, i ~ 51 deg, and beta < 90-i = 39 deg for a centered dipole. We propose that there are two components that contribute to the occurrence of DACs in \(\xi\) Per: (1) a periodic part, caused by corotation of a permanent weak dipole field, and (2) a transient part, hence cyclic, caused by transient magnetic field structures. \(\xi\) Per is the first O star with cyclical DACs and a stable underlying clock. The implication of this result for other OB stars will be discussed.

description: The Stratospheric Observatory for Infrared Astronomy (SOFIA), a joint U.S./German project, is a 2.5-meter infrared airborne telescope carried by a Boeing 747-SP that flies in the stratosphere at altitudes as high as 45,000 feet (13.72 km). This facility is capable of observing from 0.3 μm to 1.6 mm with an average transmission greater than 80 percent. SOFIA will be staged out of the NASA Dryden Flight Research Center aircraft operations facility at Palmdale, CA. The SOFIA Science Mission Operations (SMO) will be located at NASA Ames Research Center, Moffett Field, CA. First science flights began in 2010 and a full operations schedule of up to one hundred 8 to 10 hour flights per year will be reached by 2014. The observatory is expected to operate until the mid 2030's. SOFIAs initial complement of seven focal plane instruments includes broadband imagers, moderate-resolution spectrographs that will resolve broad features due to dust and large molecules, and high-resolution spectrometers capable of studying the kinematics of atomic and molecular gas at sub-km/s resolution. We describe the SOFIA facility and outline the opportunities for observations by the general scientific community and for future instrumentation development. The operational characteristics of the SOFIA first-generation instruments are summarized. The status of the flight test program is discussed and we show First Light images obtained at wavelengths from 5.4 to 37 ïm with the FORCAST imaging camera.

description: Central exclusive production (CEP) processes in high-energy hadron collisions offer a very promising framework for studying both novel aspects of QCD and new physics signals. We report on the results of a theoretical study of the CEP of heavy quarkonia (chi and eta) at the Tevatron, RHIC and LHC. These processes provide important information on the physics of bound states and can probe the current ideas and methods of QCD, such as effective field theories and lattice QCD.

description: We have investigated electronic excitations in GaAs-AlxGa1-xAs quantum wires, and dots by resonance Raman spectroscopy. We find for quantum dots and quantum wires three types of excitations; single-particle, spin-density, and charge-density excitations (SPE's, SDE's, and CDE's, respectively). Our experiments show that SPE's are enhanced under conditions of extreme resonance, which indicates that energy-density fluctuations are responsible for the excitation of unscreened SPE's. The high intensity of the SPE's allows a detailed analysis of collective effects in the zero- and one-dimensional electron systems.

PRODUZIONE INTEGRATA, AMBITO OLIVICOLTURA, Marzo 2021» καθώς και οι μεταφραστικές δυσκολίες που θα ανακύψουν κατά τη διάρκεια της μεταφραστικής διαδικασίας. Ο λόγος της μετάφρασης του συγκεκριμένου αποσπάσματος είναι το ενδιαφέρον που προκάλεσε δυσκολία των τεχνικών όρων που χρησιμοποιούνται σε αντίστοιχα κείμενα τεχνικού περιεχομένου. Η μετάφραση είτε λογοτεχνικών κειμένων είτε άλλου είδους αποτελεί μια πρόκληση για τον μεταφραστή. Σε αντίθεση με τη μετάφραση ενός λογοτεχνικού κειμένου όπου ο μεταφραστής καλείται να λάβει υπόψη του πολλούς παράγοντες που θα του επιτρέψουν να ολοκληρώσει το έργο του, στη μετάφραση ενός μη λογοτεχνικού κειμένου οι περισσότεροι όροι είναι σχεδόν ξεκάθαροι. Όμως αυτές οι προκλήσεις θα βοηθήσουν στην καλύτερη προετοιμασία όσων ασχολούνται με τη μετάφραση τεχνικών κειμένων αλλά και στην προετοιμασία των μελλοντικών μεταφραστών που θα έχουν ως αντικείμενο την τεχνική μετάφραση.
description: The aim of this thesis is to present the annotated translation of a passage from "PARASSITI MINORI DELL’OLIVO REGIONE LIGURIA – Servizi alle Imprese Agricole e Florovivaismo. PRODUZIONE INTEGRATA, AMBITO OLIVICOLTURA, Marzo 2021" and the translation difficulties that will arise during the translation process. The reason for translating this particular passage is the interest aroused by the difficulty of the technical terms used in similar technical texts. Translating either literary texts or other genres is a challenge for the translator. Contrary to the translation of a literary text where the translator is invited to take into account many factors that will enable him to complete his task, in the translation of a non-literary text most terms are almost unambiguous. However, these challenges will help to the better preparation of those involved in the translation of technical texts, as well as to the preparation of future translators who will have technical translation as their subject.

description: Atomic layer deposition of ultrathin HfO2 on unmodified graphene from HfCl4 and H2O was investigated. Surface RMS roughness down to 0.5 nm was obtained for amorphous, 30 nm thick hafnia film grown at 180 degrees C. HfO2 was deposited also in a two-step temperature process where the initial growth of about 1 nm at 170 degrees C was continued up to 10-30 nm at 300 degrees C. This process yielded uniform, monoclinic HfO2 films with RMS roughness of 1.7 nm for 10-12 nm thick films and 2.5 nm for 30 nm thick films. Raman spectroscopy studies revealed that the deposition process caused compressive biaxial strain in graphene whereas no extra defects were generated. An 11 nm thick HfO2 film deposited onto bilayer graphene reduced the electron mobility by less than 10% at the Dirac point and by 30-40% far away from it.

Multiple cyclotron resonances in GaAs-AlxGa1-xAs quantum wells detected by resonant inelastic light scattering

description: Cyclotron resonance excitations in modulation-doped AlxGa1-xAs-GaAs quantum wells have been investigated by means of resonant inelastic light scattering. Besides the cyclotron resonance excitation ħωC, we observe up to fifteen additional peaks at multiples of ħωC. The constant energy separation between these resonances indicates that they are multiple excitations of ħωC (and not higher harmonics). These multiple resonances all have nearly the same strength. For an explanation, we propose a cascade model, where the photocreated hole in the valence band couples via direct and exchange Coulomb interactions to the Fermi sea. This allows the hole to relax resonantly by creating cyclotron resonance excitations in the conduction band.

description: We investigate theoretically Raman spectra of few-electron quantum dots. Spectra obtained by an exact many-body treatment and by a time-dependent local-density approximation are compared. We show that single-particle-like excitations can be expected for systems with only six electrons. The energies of these excitations are close to the Kohn-Sham level spacings.

description: Slides presented during the Sharing Digitally. Seminar on Digital Tools and Infrastructures. Tools registries have a long history in Digital Humanities, contributing both to the cataloguing efforts of the resources used by DHers and thus to their discoverability. Developed under DARIAH coordination within the Social Sciences and Humanities Open Cloud (SSHOC) project, the SSH Open Marketplace - https://marketplace.sshopencloud.eu/ - supports SSH researchers at every step of the research data lifecycle, pooling and harmonising their key tools and services, datasets, training materials, workflows and publications. Resources are contextualised to maximise serendipity and possibility of reuse for the assets showcased. During this presentation, we will address not only what you as historians can take from this collective service, but how you can contribute and help it grow.
