A genetic basis for swim stamina differences between strains of the rainbow trout, Salmo gairdneri
Creators: name: Winz, Robert Alan
Publisher: name: University of British Columbia
Year: 2010

description: Two wild strains of British Columbia rainbow trout (Salmo gairdneri) (Deadman Creek steelhead and Pennask Lake ) and 2 domesticated strains (Domestic-McLeary and Duncan River) were compared for evidence of genetic changes in swim stamina due to natural and artificial selection in hatcheries. The wild strains had approximately twice the swim stamina of the hatchery strains, with critical swim velocities (U[sub crit]) of 1.98 ± 0.08 (Pennask) and 1.91 ± 0.1 0 (Deadman) body lengths.sec⁻¹ vs. 1.36 ± 0.09 (Domestic) and 1.10 ± 0.06 (Duncan) body lengths.sec⁻¹. These two categories of strains also differed in certain genetic/biochemical and morphological characteristics which have been linked to swimming ability. The results of this study reveal that: (1) In the exercised state, the Pennask and Deadman strains convert lactate to pyruvate in the liver at the following maximum rates: 151.92 ± 5.25 and 150.64 ± 5.74 I.U.g⁻¹ wet weight, while the Domestic and Duncan convert at slower rates: 86.48 ± 1.78 and 109.20 ± 3.11 I.U.g⁻¹. Lactate oxidation in whole blood shows a similar trend. (2) No correlation was found between swim stamina and LDH B² genotype. However the two high stamina "wild" strains were the only heterozygous groups. (3) Lactate levels in the brain showed no change with exercise in the "wild" strains, while a 2.5 fold increase was observed for the "hatchery" strains. (4) Hemoglobin concentration during exercise was higher for the Pennask and Deadman strains, 1.73 ± 0.04 and 1.75 ± 0.05 mM, vs. 1.61 ± 0.03 and 1.54 ± 0.03 mM for the Domestic and Duncan strains. (5) The percentage of non-Bohr/Root hemoglobin was approximately 30% for all 4 strains. (6) The Duncan strain was the only one to show a nucleoside triphosphate/hemoglobin (NTP/Hb) ratio of less than unity during exercise (0.89 ± 0.04). (7) This strain is also monomorphic for the rare LDH B²” allele. (8) The Deadman and Duncan strains had greater percentages of GTP in their erythrocytic NTP pools in both the exercised and baseline states. Poor survival after release into the wild is a negative characteristic of domesticated stocks of hatchery trout. A major component of the ability to survive in the wild is swim stamina. Domestication selection (a form of natural selection) in hatcheries against unnecessary swimming capacity is a potential reason why trout raised from hatchery brood stocks perform so poorly. High swim stamina is not as necessary for survival in the hatchery environment as it is in a trout's natural environment. Also, additional artificial selection for rapid growth characteristics may be mutually exclusive with any type of selection for high swim stamina.

description: We analyse the distinction between the three different ground states presented by a system of spinless bosons with short-range interactions submitted to a random potential using the disordered Bose-Hubbard model. The criteria for identifying the superfluid, the Mott-insulator, and the Bose-glass phases at finite temperatures are discussed for small values of the kinetic energy associated with the tunnelling of particles between potential wells. Field theoretical considerations are applied in order to construct a diagrammatic hopping expansion to the finite-temperature Green's function. By performing a summation of subsets of diagrams we are able to find the condition to the long-range correlations which leads to the phase boundary between superfluid and insulating phases. The perturbative expression to the local correlations allows us to calculate an approximation to the single-particle density of states of low-energy excitations in the presence of small hopping, which characterizes unambiguously the distinction between the Mott-insulator and the Bose-glass phases. We obtain the phase diagram for bounded on-site disorder. It is demonstrated that our analysis is capable of going beyond the mean-field theory results for the classification of these different ground states.

Gravitational polarization of the quantum vacuum caused by two point-like bodies

description: In a recent paper (Hajdukovic 2020a) quantum vacuum was considered as a source of gravity and, the simplest phenomenon, the gravitational polarization of the quantum vacuum by an immersed point-like body, was studied. In the present paper, we have derived the effective gravitational charge density of the quantum vacuum, caused by two point-like bodies. Among others, the obtained result proves that quantum vacuum can have regions with a negative effective gravitational charge density. Hence, quantum vacuum, the "ocean" in which all matter of the Universe is immersed, acts as a complex fluid with a very variable gravitational charge density that might include both positive and negative densities; a crucial prediction that can be tested within the Solar System. In general case of N>2 point-like bodies, immersed in the quantum vacuum, the analytical solutions are not possible, and the use of numerical methods is inevitable. The key point is that an appropriate numerical method, for the calculation of the effective gravitational charge of the quantum vacuum induced by N immersed bodies, might be crucial in description of galaxies, without the involvement of dark matter or a modification of gravity. The development of such a valuable numerical method, is not possible, without a previous (and in this study achieved) understanding of the impact of a two-body system.

description: A new formulation of potential scattering in quantum mechanics is developed using a close structural analogy between partial waves and the classical dynamics of many non-interacting fields. Using a canonical formalism we find non-linear first-order differential equations for the low energy scattering parameters like scattering length and effective range. They significantly simplify typical calculations, as we illustrate for atom-atom and neutron-nucleus scattering systems. A generalization to charged particle scattering is also possible.

title: Cultural Crossroads: British Film Music in the 1930s
Creators: name: Bennett, Alexis
Publisher: name: Goldsmiths, University of London
Year: 2019

description: This thesis gives a historical account of British film music in the 1930s, and re-interprets the period as an important artistic and cultural crossroads. The film scoring scene in the UK between the consolidation of sound film and the beginning of the Second World War was complex, rich and varied, and marked a stylistic intersection between competing and often contrasting traditions, aesthetic sensibilities, and practical approaches. The music that was produced for theatrical features and documentaries in the period grew out of a situation wherein its creators lacked a well-defined precedent for what they did. Some composers or musical directors were drawn towards experimentation; others transferred practices from other forms, such as the stage musical, operetta, or live accompaniment to silent film. In this project, I offer a detailed revision of received notions of the period in response to the lack of extant research and the assumptions of the few music scholars who have — briefly and insufficiently — examined it. The thesis arguably represents the first substantial work of scholarship on British film music of the period. 
 
The chapters that follow identify trends, tendencies, and fashions; but I also show how none of these became mainstream practice. This applies both to the methodology composers adopted when working on scores, and to the character and function of the music they wrote. I challenge assumptions about the perceived qualitative divide caused by the ‘Quota Act’ by comparing scores written for ‘quota quickies’ to music composed for ‘prestige’ productions. It is a study that assesses the modes of creative film music practice and the variety of styles produced, set against the state of the film industry and the broader cultural climate of Britain in the 1930s. The means by which this is achieved is threefold: 1) the use of primary sources such as the films themselves, manuscript scores, and other archival materials, to illuminate creative practices and aesthetic approaches; 2) in-depth assessment of secondary film-musicological texts that have brought the subject into their field of vision; and 3) the drawing-together of items of criticism and journalism of the period under study to further inform findings. 
 
A principal aim in this thesis is to demonstrate that the relative lack of scholarly attention the subject has attracted is disproportionate to the sheer variety of creative approaches to film scoring in Britain in the 1930s, and that by giving a multi-faceted overview alongside close examination of films, composers and music directors, and their scores, new perspectives on this period can be drawn.

description: We consider the possibility of adding a Grassmann-odd function νto the odd Laplacian. Requiring the total Δoperator to be nilpotent leads to a differential condition for ν, which is integrable. It turns out that the odd function νis not an independent geometric object, but is instead completely specified by the antisymplectic structure E and the density ρ. The main impact of introducing the νterm is that it makes compatibility relations between E and ρobsolete. We give a geometric interpretation of νas (minus 1/8 times) the odd scalar curvature of an arbitrary antisymplectic, torsion-free and ρ-compatible connection. We show that the total Δoperator is a ρ-dressed version of Khudaverdian's Δ_E operator, which takes semidensities to semidensities. We also show that the construction generalizes to the situation where ρis replaced by a non-flat line bundle connection F. This generalization is implemented by breaking the nilpotency of Δwith an arbitrary Grassmann-even second-order operator source.

Genotoxicity of chewing tobacco samples

description: The intra-oral use of tobacco-containing mixtures plays an important aetiological role in the occurrence of oral cancers. In vitro genotoxicity assays may provide means for the rapid evaluation of factors contributing to or modulating this form of tobacco carcinogenesis. An essential requirement for an effective test system is the capability to detect the genotoxic effects of a variety of tobacco mixtures which are expected to differ in chemical composition. Freshly prepared aqueous extracts of four tobacco mixtures, locally available snuff and "chewing" tobacco, Khaini tobacco (India) and nass (Uzbekistan, USSR), were assayed for genotoxic activity in three different test systems: chromosome aberrations in Chinese hamster ovary cells, micronuclei in Chinese hamster ovary cells and unscheduled DNA synthesis in human fibroblasts. A DNA repair inhibition test was included as a complement to the unscheduled DNA synthesis assay. All four tobacco extracts were found to contain direct acting agents capable of inducing chromosome aberrations and micronuclei formation in Chinese hamster ovary cells. Catalase was found to suppress the clastogenic activity of the chewing and Khaini tobaccos, implicating H₂O₂-mediated production of chromosome damage. The genotoxic activities of snuff and nass did not appear to be dependent on the generation of H₂O₂. Only the chewing tobacco initiated unscheduled DNA synthesis in human fibroblasts. All tobacco extracts reduced the levels of UV initiated unscheduled DNA synthesis, indicating the extracts exerted an inhibitory effect on DNA repair. The failure of the snuff, Khaini tobacco and nass to induce a demonstrable unscheduled DNA synthesis was interpreted to be a consequence of this inhibition. On the basis of these results it was concluded that the chromosome aberration and micronucleus tests in Chinese hamster ovary cells, but not the unscheduled DNA synthesis, appear to be suitable as test systems for the study of factors influencing oral tobacco carcinogenicity.

description: Empirical theories of Dark Matter like MOND gravity and of Dark Energy like f(R) gravity were motivated by astronomical data. But could these theories be branches rooted from a more general hence natural framework? Here we propose the natural Lagrangian of such a framework based on simple dimensional analysis and co-variant symmetry requirements, and explore various outcomes in a top-down fashion. Our framework preserves the co-variant formulation of GR, but allows the expanding physical metric be bent by a single new species of Dark Fluid flowing in space-time. Its non-uniform stress tensor and current vector are simply functions of a vector field of variable norm, resembling the 4-vector electromagnetic potential description for the photon fluid, but is dark (e.g., by very early decoupling from the baryon-radiation fluid). The Dark Fluid framework naturally branches into a continuous spectrum of theories with Dark Energy and Dark Matter effects, including the $f(R)$ gravity, TeVeS-like theories, Einstein-Aether and $νΛ$ theories as limiting cases. When the vector field degenerates into a pure Higgs-like scalar field, we obtain the physics for inflaton and quintessence. In this broad setting we emphasize the non-constant dynamical field behind the cosmological constant effect, and highlight plausible corrections beyond the classical MOND predictions. Choices of parameters can be made to pass BBN, PPN, and causality constraints. The Dark Fluid is inspired to unify/simplify the astronomically successful ingredients of previous constructions: the desired effects of inflaton plus quintessence plus Cold DM particle fields or MOND-like scalar field(s) are shown largely achievable by one vector field only.

description: We calculate the important next-to-leading-order (NLO) contributions to the $B \to K K^*$ decays from the vertex corrections, the quark loops, and the magnetic penguins in the perturbative QCD (pQCD) factorization approach. The pQCD predictions for the CP-averaged branching ratios are $Br(B^+ \to K^+ \bar{K}^{*0}) \approx 3.2\times 10^{-7}$, $Br(B^+ \to \bar{K}^0 {K}^{*+}) \approx 2.1\times 10^{-7}$, $Br(B^0/\ov{B}^0 \to K^0\bar{K}^{*0}+\bar{K}^0 K^{*0}) \approx 8.5\times 10^{-7}$, $Br(B^0/\ov{B}^0 \to K^+K^{*-} + K^-K^{*+}) \approx 1.3\times 10^{-7}$, which agree well with both the experimental upper limits and the predictions based on the QCD factorization approach. Furthermore, the CP-violating asymmetries of the considered decay modes are also evaluated. The NLO pQCD predictions for $\acp(B^+ \to K^+\bar{K}^{*0})$ and $\acp(B^+ \to K^{*+}\bar{K}^{0})$ are $\acp^{dir}(K^+\bar{K}^{*0})\approx -6.9 %$ and $\acp^{dir}(K^{*+}\bar{K}^0)\approx 6.5 %$.

description: We investigate the ground-state properties of a collection of \textit{N} non-interacting electrons in a macroscopic volume $Ω$ also containing a crystalline array of \textit{N} spheres of radius $r_c$ each taken as largely impenetrable to electrons and with proximity of neighboring excluding regions playing a key physical role. The sole parameter of this quantum system is the ratio $r_c/r_s$, where $r_s$ is the Wigner- Seitz radius. Two lattices (FCC and BCC) are selected to illustrate the behavior of the system as a function of $r_c/r_s$. As this ratio increases valence electrons localize in the interstitial regions and the relative band-width $ε_F/ε_F^0$ is found to decrease monotonically for both. The system is motivated by the behavior of the alkali metals at significant compression. It accounts for band narrowing, leads to electronic densities with interstitially centered maxima, and can be taken as a model which clearly may be improved upon by perturbation and other methods.

description: Magnetars are one of the potential power sources for some energetic supernova explosions such as type I superluminous supernovae (SLSNe I) and broad-lined type Ic supernovae (SNe Ic-BL). In order to explore the possible link between these two subclasses of supernovae (SNe), we study the effect of fallback accretion disk on magnetar evolution and magnetar-powered SNe. In this scenario, the interaction between a magnetar and a fallback accretion disk would accelerate the spin of the magnetar in the accretion regime but could result in substantial spin-down of the magnetars in the propeller regime. Thus, the initial rotation of the magnetar plays a less significant role in the spin evolution. Such a magnetar-disk interaction scenario can explain well the light curves of both SNe Ic-BL and SLSNe I, for which the observed differences are sensitive to the initial magnetic field of the magnetar and the fallback mass and timescale for the disk. Compared to the magnetars powering the SNe Ic-BL, those accounting for more luminous SNe usually maintain faster rotation and have relatively lower effective magnetic fields around peak time. In addition, the association between SLSNe I and long gamma-ray bursts, if observed in the future, could be explained in the context of magnetar-disk system.

Impacts of tropical forest modification on soil microbial communities, function and resilience
Creators: name: Elias, Dafydd
Publisher: name: Lancaster University
Year: 2021

description: Tropical forests are hotspots of biodiversity and have global significance to the terrestrial carbon cycle. However, forest disturbance, clearance for plantation agriculture and future climate change are threatening their ability to sustain crucial ecosystem services. Ecosystem processes in tropical forests are underpinned by soil microbial activity, but knowledge of the principal drivers of microbial community dynamics and relationship to ecosystem functions is lacking. An improved understanding is therefore essential to better predict the response of tropical forests to a changing environment. The overarching aim of this thesis was to determine environmental drivers of soil microbial communities in tropical forest and explore the effects of forest modification (degradation and conversion) on soil microbial community composition, functioning and resilience to climate perturbations. Using a combination of field survey, in situ ecological manipulations and controlled laboratory experiments I found that fungal communities had stronger local covariance with standing tree communities and were thus more strongly influenced by tropical forest disturbance than bacterial communities. Moreover, the relative abundance of ectomycorrhizal fungi was strongly associated with the standing biomass of dipterocarp trees. In old growth forest, ants were found to modulate fungal growth rates and termites influenced the abundance and distribution of wood degrading taxa. Suppressed ant and termite activity also restructured microbial networks with properties associated with reduced resilience to climate extremes. As logging alters the functional diversity of ants and strongly reduces termite abundance in tropical forest, these findings indicate that invertebrate – microbial interactions may control the fungal contribution to soil C storage, rates of wood decomposition, and the resilience of soil microbial decomposers to future climate extremes across OG and SL tropical forests. Microbial communities in SL forest did have lower resilience to experimental drought – rewetting relative to those in OG forest and oil palm plantations whilst communities in old growth tropical forest had broader functional abilities, degrading both forest and oil palm litters faster than communities from logged forest and oil palm plantations. Taken together, these findings suggest that logging of tropical forests reduces the function and resilience of soil microbial communities, by modifying tree community composition and invertebrate activity. This may influence the size and stability of soil C stocks under future climate change.
Modelling the DC performance of GAAS Homojunction bipolar transistors
Creators: name: Lee, Soon Peng
Publisher: name: University of British Columbia
Year: 2010

description: Two models, one analytical and one numerical, have been developed to predict the dc performance of GaAs homojunction bipolar transistors. In each case the minority carrier properties of lifetime and mobility have been described by polynomial fits to recent data. Bandgap narrowing in the emitter and base regions has also been taken into account. The analytical model assumes uniform doping in the three regions of the transistor and is thus appropriate to predicting the performance of devices fabricated using epitaxial technologies. This model is also useful for carrying out sensitivity analyses. The importance of parameters such as regional widths and doping densities, minority carrier lifetimes and surface recombination velocity is examined here. The numerical model is useful for describing the performance of ion-implanted devices. Good agreement is obtained between results from the model and recent experimental data from prototype devices.

Despite some limitations, SAS Proc MIXED is a useful tool that may be easily extendable to multivariate response in longitudinal studies.

description: A large fraction of known terrestrial-size exoplanets located in the Habitable Zone of M-dwarfs are expected to be tidally-locked. Numerous efforts have been conducted to study the climate of such planets, using in particular 3-D Global Climate Models (GCM). One of the biggest challenges in simulating such an extreme environment is to properly represent the effects of sub-grid convection. Most GCMs use either a simplistic convective-adjustment parametrization or sophisticated (e.g., mass flux scheme) Earth-tuned parametrizations. One way to improve the representation of convection is to study convection using Convection Resolving numerical Models (CRMs), with an fine spatial resolution . In this study, we developed a CRM coupling the non-hydrostatic dynamical core WRF with the radiative transfer and cloud/precipitation models of the LMD-Generic climate model to study convection and clouds on tidally-locked planets, with a focus on Proxima b. Simulations were performed for a set of 3 surface temperatures (corresponding to three different incident fluxes) and 2 rotation rates, assuming an Earth-like atmosphere. The main result of our study is that while we recover the prediction of GCMs that (low-altitude) cloud albedo increases with increasing stellar flux, the cloud feedback is much weaker due to transient aggregation of convection leading to low partial cloud cover.

description: The underdamped, non-linear, generalized Langevin equation is widely used to model coarse-grained dynamics of soft and biological materials. By means of a projection operator formalism, we show under which approximations this equation can be obtained from the Hamiltonian dynamics of the underlying microscopic system and in which cases it makes sense to introduce a potential of mean force. We discuss shortcomings of previous derivations presented in the literature and demonstrate the implications of our derivation for the structure of memory terms and their connection to generalized fluctuation-dissipation relations. We show, in particular, that the widely used, simple structure which contains a potential of mean force, a memory term which is linear in the observable, and a fluctuating force which is related to the memory term by a fluctuation-dissipation relation, is neither exact nor can it, in general, be derived as a controlled approximation to the exact dynamics.

description: Spectro-astrometry is used to investigate the low velocity component (LVC) of the optical forbidden emission from the T Tauri stars RU Lupi and AS 205 N. Both stars also have high velocity forbidden emission (HVC) which is tracing a jet. For AS 205 N, analysis reveals a complicated outflow system. For RU Lupi, the [O I] 6300 and [S II] 6716, 6731 LV narrow component (NC) is offset along the same position angle (PA) as the HVC but with a different velocity gradient than the jet, in that displacement from the stellar position along the rotation axis is decreasing with increasing velocity. From the LVC NC PA and velocity gradient, it is inferred that the NC is tracing a wide angled MHD disk wind. A photoevaporative wind is ruled out. This is supported by a comparison with a previous spectro-astrometric study of the CO fundamental line. The decrease in offset with increasing velocity is interpreted as tracing an increase in the height of the wind with increasing disk radius. This is one of the first measurements of the spatial extent of the forbidden emission line LVC NC (~ 40 au, 8 au for RU~Lupi in the [S II] 6731 and [O I] 6300 lines) and the first direct confirmation that the LVC narrow component can trace an MHD disk wind.

description: The nature of the link between identity and action is a fundamental question for social science. One focus in psychology is how actions like seeking help are implicated in matters of identity. This paper presents a discursive psychology study of identity and help in social interaction. Drawing on a corpus of nearly 400 recorded calls to a victim support helpline, I analysed how participants oriented to the link between identity and help. With attention to epistemic, deontic, and affective relations between participants, I analysed how identity was demonstrably relevant and procedurally consequential for building and interpreting help-seeking requests. Participants displayed an understanding that seeking help from Victim Support necessarily implicates identity. Callers’ identities as victims or clients rendered their help-seeking accountable and invoked identities for call-takers as representatives of a support service. The findings show that identity and help are mutually constitutive. Seeking help constituted callers’ identities as victims; and their identities as victims constituted their requests for help. I suggest that analysing identity and help in social interaction provides evidence for the mutually constitutive link between identity and action.

description: Scientific impact has been the center of extended debate regarding its accuracy and reliability. From hiring committees in academic institutions to governmental agencies that distribute funding, an author's scientific success as measured by the h-index is a vital point to their career. The objective of this work is to investigate whether the collaboration patterns of an author are good predictors of the author's future $h$-index. Although not directly related to each other, a more intense collaboration can result into increased productivity which can potentially have an impact on the author's future $h$-index. In this paper, we capitalize on recent advances in graph neural networks and we examine the possibility of predicting the $h$-index relying solely on the author's collaboration and the textual content of a subset of their papers. We perform our experiments on a large-scale network consisting of more than $1$ million authors that have published papers in computer science venues and more than $37$ million edges. The task is a six-months-ahead forecast, i.e. what the $h$-index of each author will be after six months. Our experiments indicate that there is indeed some relationship between the future $h$-index of an author and their structural role in the co-authorship network. Furthermore, we found that the proposed method outperforms standard machine learning techniques based on simple graph metrics along with node representations learned from the textual content of the author's papers.

Bloch-Nordsieck Estimates of High-Temperature QED

description: In anticipation of a subsequent application to QCD, we consider the case of QED at high temperature. We introduce a Fradkin representation into the exact, Schwingerian, functional expression of a fermion propagator, as well as a new and relevant version of the Bloch-Nordsieck (BN) model, which extracts the soft contributions of every perturbative graph, in contradistinction to the assumed separation of energy scales of previous semi-perturbative treatments. Our results are applicable to the absorption of a fast particle which enters a heat bath, as well as to the propagation of a symmetric pulse within the thermal medium due to the appearance of an instantaneous, shock-wave-like source acting in the medium. An exponentially-decreasing time dependence of the incident particle's initial momentum combines with a stronger decrease in the particle's energy, estimated by a sum over all Matsubara frequencies, to model an initial "fireball", which subsequently decays in a Gaussian fashion. When extended to QCD, qualitative applications could be made to RHIC scattering, in which a fireball appears, expands and is damped away.

Towards exhaustive branch coverage with PathCrawler

description: Branch coverage of source code is a very widely used test criterion. Moreover, branch coverage is a similar problem to line coverage, MC/DC and the coverage of assertion violations, certain runtime errors and various other types of test objective. Indeed, establishing that a large number of test objectives are unreachable, or conversely, providing the test inputs which reach them, is at the heart of many verification tasks. However, automatic test generation for exhaustive branch coverage remains an elusive goal: many modern tools obtain high coverage scores without being able to provide an explanation for why some branches are not covered, such as a demonstration that they are unreachable. Concolic test generation offers the promise of exhaustive coverage but covers paths more efficiently than branches. In this paper, I explain why, and propose different strategies to improve its performance on exhaustive branch coverage. A comparison of these strategies on examples of real code shows promising results.
Quantum communications in a moderate-to-strong turbulent space

description: Since the invention of the laser in the 60s, one of the most fundamental communication channels has been the free-space optical channel. For this type of channel, a number of effects generally need to be considered, including diffraction, refraction, atmospheric extinction, pointing errors and, most importantly, turbulence. Because of all these adverse features, the free-space optical (FSO) channel is more difficult to study than a stable fiber-based link. For the same reasons, only recently it has been possible to establish the ultimate performances achievable in quantum communications via free-space channels, together with practical rates for continuous variable (CV) quantum key distribution (QKD). Differently from previous literature, mainly focused on the regime of weak turbulence, this work considers the FSO channel in the more challenging regime of moderate-to-strong turbulence, where effects of beam widening and breaking are more important than beam wandering. This regime may occur in long-distance free-space links on the ground, in uplink to high-altitude platform systems (HAPS) and, more interestingly, in downlink from near-horizon satellites. In such a regime we rigorously investigate ultimate limits for quantum communications and show that composable keys can be extracted using CV-QKD.

Mixed models for longitudinal left-censored repeated measures

description: Longitudinal studies could be complicated by left-censored repeated measures. For example, in Human Immunodeficiency Virus infection, there is a detection limit of the assay used to quantify the plasma viral load. Simple imputation of the limit of the detection or of half of this limit for left-censored measures biases estimations and their standard errors. In this paper, we review two likelihood-based methods proposed to handle left-censoring of the outcome in linear mixed model. We show how to fit these models using SAS Proc NLMIXED and we compare this tool with other programs. Indications and limitations of the programs are discussed and an example in the field of HIV infection is shown.
Emanuele Trevi e la teoria iniziatica della letteratura

Subjects: Iniziazione; letteratura contemporanea; religione; M. Eliade; P. Citati; G. Celati

description: Nello scrittore Emanuele Trevi è possibile rinvenire una teoria iniziatica della letteratura. Essa concepisce il testo letterario sia come vettore di trasformazione per il fruitore sia come depositario dell’originaria cultura iniziatica, accesso alle verità nascoste dell’esistenza. Il testo appare come uno degli ultimi, se non l’ultimo, contenitore di questa sapienza primordiale: centrale nelle società e nelle religioni antiche, oggi tale grande codice appare sostanzialmente perduto. Interlocutori di Trevi sono storici delle religioni (Schuré, Corbin, Eliade), narratori (Apuleio, Melville, Collodi, V. Woolf, Joyce), protagonisti in prima persona di viaggi iniziatici (Artaud), filosofi e critici (Agamben, Zolla, Citati, Calasso, C. Campo). La teoria elaborata da Trevi sembra voler uscire da un esclusivo perimetro letterario e recuperare una dimensione antropologica dell’espressività simbolica che contenga anche, in uno stretto circolo ermeneutico, musica e pittura. La letteratura si avvicina in ultima analisi a un‘esperienza di apprendistato e a un rito sacro.
In Emanuele Trevi’s work it is possible to trace an initiatory theory of literature, conceiving the literary text both as vector of transformation for the reader and as a repository of initiatic culture, providing access to the hidden truths of existence. The text appears as one of the last, if not the last, container of this primordial wisdom: central in the ancient society and religion, today such great code substantially seems to be lost. Trevi’s fellows are historians of religion (Schuré, Corbin, Eliade), narrators (Apuelio, Melville, Collodi, Woolf, Joyce), protagonists of trips (Artaud), philosophers and critics (Agamben, Zolla, Citati, Calasso, C. Campo). Trevi’s theory apparently moves beyond the perimeter of literature, recovering an anthropological di- mension of symbolic expression that also features, in a narrow hermeneutical circle, music and painting. Thus literature draws near to an experience of apprenticeship and a sacred rite.

description: Electronic excitations near the surface of water ice lead to the desorption of adsorbed molecules, through a so far debated mechanism. A systematic study of photon-induced indirect desorption, revealed by the spectral dependence of the desorption (7 to 13 eV), is conducted for Ar, Kr, N2, and CO adsorbed on H2O or D2O amorphous ices. The mass and isotopic dependence and the increase of intrinsic desorption efficiency with photon energy all point to a mechanism of desorption induced by collisions between adsorbates and energetic H or D atoms, produced by photodissociation of water. This constitutes a direct and unambiguous experimental demonstration of the mechanism of indirect desorption of weakly adsorbed species on water ice, and sheds new light on the possibility of this mechanism in other systems. It also has implications for the description of photon-induced desorption in astrochemical models.

description: La prima parte della Chanson de la croisade contre les albigeois, composta da Guilhem de Tudela, è un osservatorio privilegiato per studiare i meccanismi dell’enunciazione in un testo medievale scritto in vista della recitazione. Viene dapprima studiato il gioco tra prima e terza persona singolare, che denotano il narratore implicito e l’autore, con alcune zone di ambiguità tra le due istanze. Sono poi presi in considerazione i contesti in cui appaiono i termini metaletterari canso, libre, estoria, gesta, gloza. I risultati dell’analisi sono esaminati alla luce della teatralità intrinseca alla letteratura medievale.

The first part of the Chanson de la croisade contre les albigeois, written by Guilhem de Tudela, is a good starting point to study énonciation strategies in a medieval text, which was written to be orally performed. The author takes into consideration the interplay between the first and the third persons of the singular that are used to refer to the narrator and the author; sometimes the narrative I overlaps with the author. The use of technical words such as canso, libre, estoria, gesta, gloza by Guilhem de Tudela is then examined in the frame set in the first part of the article. The facts established in the first two parts are then examined in the light of the theatrical features of medieval literature itself.
