description: The chronic low-level exposure of humans to toxic metal pollutants is associated with severe adverse health effects, but the involved biomolecular mechanisms in the bloodstream - which ultimately define the exposure-response relationships - are incompletely understood. The inorganic pollutants that I focused on include the nephrotoxin Hg2+ and the carcinogen Cd2+. Human serum albumin (HSA) - the most abundant plasma protein - has distinct binding sites for Hg2+ and Cd2+ and it is implicated in their delivery to target organs, but the role that L-cysteine (Cys) and D,L-homocysteine (hCys) play in this process is less well understood. To gain insight into the roles that these biomolecules play in this translocation from bloodstream to target organs I applied analytical tools. In the first step, we identified the toxicologically relevant Cd-Cys complexes that can be formed under physiological conditions of blood plasma. To this end, we employed an anion exchange HPLC column coupled to a flame atomic absorption spectrometer (FAAS) and we used a mobile phase that resembled protein free blood plasma. The observation of the retention behaviour of Cd2+ on this HPLC-FAAS system as a function of increasing Cys concentrations allowed us to observe the on-column formation of mixed CdCysxCly complexes, some of which were characterised by X-ray absorption spectroscopy. In the second step, we wanted to gain insight into the role that HSA plays in the translocation of Hg2+ and Cd2+ to organs. To this end, a size-exclusion chromatography (SEC) coupled on-line to an inductively coupled plasma atomic emission spectrometer (ICP-AES) was employed. The injection of an HSA-Hg/Cd complex with increasing mobile phase concentrations of Cys and hCys allowed us to observe the integrity of the HSA-Hg/Cd complex, which provided new insight into the translocation of Cd2+ and Hg2+ to toxicological target organs.
Study of fluid flow in the porous media of gas diffusion layers in proton exchange membrane fuel cells

description: A proton exchange membrane (PEM) fuel cell is an energy converting system generating electricity by oxidation of hydrogen and reduction of oxygen with water and heat as the only waste products. Despite the huge market potential of the fuel cell, its performance and cost must be improved significantly before constituting a viable market. One of the major problems of current fuel cells is water management: at energy demanding conditions where the cell is operating at high current densities, excessive water produced restricts the access of reactant gases and hence reduces the performance of the cell. To improve water management, it is necessary to study water transport mechanisms in the internal network of the cell, especially in the porous gas diffusion layer (GDL) through which transport of electrons, reactant gases, and water occurs. In this thesis, fluid flow through the GDL is studied experimentally and numerically using fluorescence microscopy and a pore network modeling approach, respectively. The images obtained from the microscope are analyzed to find patterns of flow inside the GDL samples with different hydrophobicity. Three different flow patterns are observed: initial invasion, progression, and pore-filling. The observations show that liquid water flows into the majority of available pores on the boundary of the hydrophilic (untreated) GDL and several branches segregate from the initial pathways. For the hydrophobic (treated) GDL, however, a handful of boundary pores are invaded and the original pathways extend toward the other side of the medium with minimum branching. In addition to flow visualization, the experimental setup facilitates the precise measurement of pressure and time of breakthrough which are used as boundary condition and the validation criterion for the numerical simulation, respectively. The numerical model, developed based on an invasion percolation algorithm, is used to study the effects of GDL hydrophobicity and thickness on the flow configuration and breakthrough time as well as to determine the flow rate and saturation in different GDL samples. The developed model can be used to optimize the GDL properties for designing porous medium with an effective transport characteristic.

description: In General Relativity, the average velocity field of dark matter around galaxy clusters is uniquely determined by the mass profile. The latter can be measured through weak lensing. We propose a new method of measuring the velocity field (phase space density) by stacking redshifts of surrounding galaxies from a spectroscopic sample. In combination with lensing, this yields a direct test of gravity on scales of 1-30 Mpc. Using N-body simulations, we show that this method can improve upon current constraints on f(R) and DGP model parameters by several orders of magnitude when applied to upcoming imaging and redshift surveys.

description: We propose a novel algebraic framework for treating probability distributions represented by their cumulants such as the mean and covariance matrix. As an example, we consider the unsupervised learning problem of finding the subspace on which several probability distributions agree. Instead of minimizing an objective function involving the estimated cumulants, we show that by treating the cumulants as elements of the polynomial ring we can directly solve the problem, at a lower computational cost and with higher accuracy. Moreover, the algebraic viewpoint on probability distributions allows us to invoke the theory of Algebraic Geometry, which we demonstrate in a compact proof for an identifiability criterion.

Tonic and Phasic Endocannabinoid Regulation of the Stress Response
Creators: name: Petrie, Gavin Norberg
Publisher: name: Graduate Studies
Year: 2023
Subjects: subject: Education--Sciences

description: Exposure to a real or perceived threat elicits multiple behavioral and physiological consequences collectively known as the stress response. One consequence is the activation of the hypothalamic pituitary adrenal (HPA) axis, where release of corticotropin-releasing hormone (CRH) from the paraventricular nucleus of the hypothalamus (PVN) results in elevated circulating corticosterone (CORT). CRH neurons in the PVN (CRHPVN) are also implicated in several stress-induced behaviors, such as grooming. Although the physiological processes involved in responding to a stressor have been relatively well elucidated, less attention has been paid to what gates this response in the absence of a threat. The endocannabinoid (eCB) is involved in many arms of the stress response. However, current research paints a superficial picture of how eCB signaling provides tonic and phasic regulation of the stress response. This thesis utilizes cellular, neuroendocrine and behavioral measures together to capture a broad picture of how tonic and phasic eCB signaling regulates the stress response. Aim1: Systemic administration of a CB1 receptor antagonist/inverse agonist (AM251), neutral antagonist (NESS0327) and AEA synthesis inhibitor (LEI401) all elevated cellular activity in the PVN, circulating CORT and homecage grooming behaviors, suggesting a role for AEA as the tonic regulator of the stress response. Intra-PVN AM251 administration increased stress-like grooming and circulating CORT, providing evidence for local tonic eCB signaling in gating the stress response in the absence of a stressor. Aim2: Pharmacological blockade of 2-AG degradation, but not AEA, with JZL184 accelerated the behavioral recovery following a footshock stressor, while elevating c-fos expression in the PVN and circulating CORT. Intra-PVN JZL184 infusions recapitulated the behavioral effects of systemic administrations while also blunting stress-induced increases in circulating CORT. Systemic JZL184 administrations had a biphasic influence on CRHPVN neuron activity, amplifying population activity in a threatening environment but accelerating CRHPVN recovery following return to homecage. Overall, these data identify AEA as a tonic gatekeeper of the stress response in the absence of a threat and 2-AG as providing a phasic response to a stressful stimulus, shutting the stress response down during recovery. These data provide the groundwork necessary to develop therapies targeting the treatment of stress-related disorders.

description: Generalized Pauli's theorem, proved by D. S. Shirokov for two sets of anticommuting elements of a real or complexified Clifford algebra of dimension $2^n$, is extended to the case, when both sets of elements depend smoothly on points of Euclidian space of dimension $r$. We prove that in the case of even $n$ there exists a smooth function such that two sets of Clifford algebra elements are connected by a similarity transformation. All cases of connection between two sets are considered in the case of odd $n$. Using the equation for the spin connection of general form, it is shown that the problem of the local Pauli's theorem is equivalent to the problem of existence of a solution of some special system of partial differential equations. The special cases $n=2$, $r\geq 1$ and $n\geq 2$, $r=1$ with more simpler solution of the problem are considered in detail.

Enriched Story Experiences with a New Video Interaction Model

Subjects: subject: interactive film

subject: Computer Science

description: Interactive film is a video storytelling medium lying between films and video games. It traditionally gives users choices at fixed points. This supports non-linear storylines, as the user can influence what happens in the plot by making decisions. However, such films are tightly scripted, and limited in handling users with different needs for interactions. Passive film viewers may find frequent choices disruptive, while active users may feel such choices are shallow and confining. These issues contribute to interactive films being a niche form of entertainment. To lift these restrictions of the standard choice-based interactive film, this thesis proposes a novel anytime interaction film model where users can choose when, and how much to interact. At anytime, users can activate a switching mechanism to enter an interactive mode. This opens a variety of voluntary, plot-relevant interactions in an explorable virtual environment. These broadened interactive possibilities heighten the enjoyment and depth of the system. Furthermore, the complete user experience is personalized by implicitly guiding users to suitable interactions and branching storylines. Interaction guidance streamlines the recommendation of content to adapt to different user preferences. This module is achieved with the online learning of contextual bandits, using domain-specific features. Conversely, a story guidance module performs implicit emotion recognition on the user, as they engage with conversational agents representing story characters. Powered by natural language generation, these agents can discuss any topic the user wishes. Aside from granting an ongoing source of interaction, these agent conversations help model the user’s character preferences. Based on these feelings, suitable storylines for the user can be selected with little authorial scripting. Through user studies and simulations, the worth of these features in enhancing user engagement and autonomy was realized. The new features of environmental exploration and character agents improved user satisfaction. User feedback also suggested this model’s strengthened flexibility was appealing. Furthermore, simulation of the personalization schemes indicated their potential in accommodating different types of users and scenarios. This unique anytime interaction film model eases authorial burden while granting an adaptive user experience, driving a new form of video storytelling.

description: Introduction: The majority of dance injury research has examined pre-professional and professional ballet and contemporary dancers. Most dancers begin their training in a private studio environment at a young age and train in a variety of dance styles, however the studio dance population has largely been left out of the research. Objective: To describe the participation and injury trends among pre-adolescent studio dancers, as well as the feasibility of further research in the studio dance population. Methods: Validity and reliability study and cross-sectional study designs. Dancer participants were recruited from private dance studios across Alberta, Canada. The validity and reliability study (VRS) utilized a 4-stage process to design and evaluate a novel questionnaire (Pre-Adolescent Dance Injury and Participation Questionnaire [PADIP-Q]): initial questionnaire design based on previous literature, expert panel review (n=9), cognitive interviews (n=6) and test-retest reliability (n=28). The cross-sectional study (CSS) used the PADIP-Q to examine demographics, dance training, and injury among pre-adolescent studio dancers, 19 private dance studios participated, and 56 dancers (age 7-12 years) completed the questionnaire reflecting on the previous 1-year (1y) and previous 4-months (4m). Results: For the VRS, key recommendations for revision of the PADIP-Q included vocabulary adjustment, inclusion of operational definitions, additional categorization of dance classes and styles, and layout adjustments. Reliability assessment demonstrated good to excellent reliability across all items of the questionnaire (categorical: Cohen’s kappa coefficients (k) 0.32-1.00, percent agreement (%A) 81-100%; numerical: Interclass correlation coefficients (ICC) 0.14-1.00, Pearson’s correlation coefficients (r) 0.14-1.00, largest absolute mean difference (md) 0.46). For the CSS, 36% (95%CI 0.22,0.52)(1y) and 29%(95%CI 0.16,0.45)(4m) of participants reported an injury, 70%(1y) and 75%(4m) of reported injuries were acute (1y:70%; 4m:75%), and muscle strains (1y:35; 4m:55%) or joint sprains (1y:25; 4m:29%). Dancers reported training in multiple styles and median dance hours as 6.9 hours/week(1y) and 7.0 hours/week(4m). Conclusion: The PADIP-Q was found to be valid and reliable for use with pre-adolescent private studio dancers. Pre-adolescent studio dancers train for several hours each week in a variety of dance styles; they are also experiencing acute injuries that affect their ability to fully participate in dance. To develop effective injury prevention and rehabilitation strategies, further study is needed.

It relies on a fully numerical method and is applicable to a wide class of integrals with various mass configurations. As an example, the computation of two-loop planar and non-planar box diagrams is shown. The results are confirmed by comparisons with other techniques, including the reduction method, and by a consistency check using the dispersion relation.

Improved spread spectrum schemes for data hiding and their security analysis under known message attack

Publisher: name: University of British Columbia
Year: 2013

description: The massive production and easy use of digital media pose new challenges on protecting intellectual property of digital media. Digital data hiding, which can be defined as the procedure of embedding information into an original media host signal, is a promising technique for digital intellectual property protection. A data hiding system generally contains two major components: the encoder for embedding the hidden information and the decoder for extracting the hidden information. This thesis focuses on spread spectrum (SS) watermarking schemes for data hiding. Watermarking techniques for data hiding can be broadly categorized into two classes: quantization index modulation (QIM) based and spread spectrum based approaches. Being robust against distortions and having simple decoder structure make SS attractive for data hiding. First, we investigate the decoding performance of the traditional SS schemes in the DCT and DFT domains. To obtain more practical decoders, we propose using suboptimal decoders which do not need side information. Secondly, since the interference effect of the host signal causes decoding performance degradation in the additive SS scheme, to remove this host effect efficiently, we propose the correlation-and-bit-aware concept for data hiding by exploiting the side information at the encoder side and propose two improved SS-based schemes, the correlation-aware SS (CASS) and the correlation-aware improved SS (CAISS) embedding schemes. Thirdly, we analyze the decoding error probability and capacity of the multiplicative spread spectrum (MSS) embedding scheme, and show that the content-based MSS still suffers from the interference effect of the host signal. We then propose an improved MSS-based scheme by efficiently removing the host interference effect. Lastly, we present the security analysis of the SS-based data hiding schemes under the Known Message Attack (KMA) scenario. Each data hiding scheme has some secret parameters and here the security of a data hiding scheme represents the difficulty of estimating the secret parameters. We employ the mutual information between the observations and the secret parameters as a security measure. Also some practical estimators for estimating the signature code are introduced and their performances are reported to illustrate the security results.

description: On the basis of ab-initio pseudopotential calculations, we study structural, magnetic, dynamical, and mechanical properties of the hypothetical CaC ionic compound in the rock-salt (RS), B2, zinc-blende (ZB), wurtzite (WZ), NiAs (NA), anti-NiAs (NA*), and CrB (B33) structures. It is argued that the ZB, WZ, NA, and RS structures are more ionic while the NA*, B2, and B33 structures are more covalent systems. As a result of that, the nonmagnetic B33-CaC is the energetically preferred system, while the more ionic structures prefer a ferromagnetic ground state with high Fermi level spin polarization. The observed ferromagnetism in the more ionic systems is attributed to the sharp partially filled $p$ states of carbon atom in the system. In the framework of density functional perturbation theory, the phonon spectra of these systems are computed and the observed dynamical instabilities of the NA* and B2 structures are explained in terms of the covalent bonds between carbon atoms. The calculated Helmholtz and Enthalpy free energies indicate the highest stability of the B33 structure in a wide range of temperatures and pressures. Among the ferromagnetic structures, RS-CaC and ZB-CaC are reported, respectively, to be the most and the least metastable systems in various thermodynamics conditions. Several mechanical properties of the dynamically stable structures of CaC are determined from their phonon spectra.

description: This paper aims to acquaint the reader with the works of Serge Gruzinski. Historian, professor at the École des Hautes Études en Sciences Sociales (Paris), since the 1980s Gruzinski has put the phenomenon of globalization into an historical perspective. From La colonisation de l'imaginaire (1988) up to Quelle heure est-il là bas? (2008), through Les Quatre parties du monde (2004) and the exhibition La planète métisse (Paris, Musée du Quai Branly, 2008-2009), Gruzinski has developed his scientific task from a very original point of view. With a special focus on Mexico and the Spanish-American experience, he has in fact followed the hints of globalization in the long period of history of civilizations, cultures, peoples and individuals. His works cross many frontiers. By connecting different spaces and times, different sources and scholarly traditions, the researches analyzed in this paper expose the reader to the whole gamut of cultural experiences fostered by globalization. In Gruzinski's perspective, history, far from being an ancilla of social sciences, remains the fundamental tool to understand and cope with the huge political and cultural changes of contemporary international life whose origins are rooted in the early modern age (XV-XVI century).

description: The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its variants is threatening the public health around the world. Endocytosis functions as an important way for viral infection, and SARS-CoV-2 bears no exception. However, the specific endocytic mechanism of SARS-CoV-2 remains unknown. In this study, we used endocytic inhibitors to evaluate the role of different endocytic routes in SARS-CoV-2 pseudovirus infection and found that the viral infection was associated with caveolar/lipid raft- and cytoskeleton-mediated endocytosis, but independent of the clathrin-mediated endocytosis and macropinocytosis. Meanwhile, the knockdown of CD147 and Rab5a in Vero E6 and Huh-7 cells inhibited SARS-CoV-2 pseudovirus infection, and the co-localization of spike protein, CD147, and Rab5 was observed in pseudovirus-infected Vero E6 cells, which was weakened by CD147 silencing, illustrating that SARS-CoV-2 pseudovirus entered host cells via CD147-mediated endocytosis. Additionally, Arf6 silencing markedly inhibited pseudovirus infection in Vero E6 and Huh-7 cells, while little change was observed in CD147 konckout-Vero E6 cells. This finding indicated Arf6-mediated CD147 trafficking plays a vital role in SARS-CoV-2 entry. Taken together, our findings provide new insights into CD147-Arf6 axis in mediating SARS-CoV-2 pseudovirus entry into the host cells and further suggest that blockade of this pathway seems to be a feasible approach to prevent SARS-CoV-2 infection clinically.

description: Since the beginning of the twentieth century, the issue of otherness has been central in the intellectual debate among ethnologists, linguists and philosophers.  Communication can be seen as a form of translation of the Other into the language of the Self, and a parallel can indeed be established between translation and the knowledge of other peoples and cultures. As a matter of fact, in order to provide a diligent translation one has to overcome both linguistic difficulties and psychological resistances.

The first eighteenth-century adventure stories and travel accounts provided biased descriptions of foreign countries and their un-European habits. The western traveler tended in fact to absorb or even force the inhabitants of other countries into his own idea of the ‘right' civilisation.

A new approach towards the issue of otherness begins with the work of researchers such as Lévi-Strauss who support their knowledge of ‘other' cultures only through systematic anthropological fieldwork. Similarly, in linguistics, theorists such as Berman and Meschonnic focus on the need to know all the elements composing a text in order to perform a good translation of that text: there should be an ";intimate distance"; between the translator and his/her text, similar to the one existing, in psychoanalysis, between an analyst and his/her patient. Paul Ricœur suggests the notion of linguistic hospitality, a notion that goes beyond problems of mere understanding. And the ethno-psychotherapist Marie Rose Moro proposes an approach to the Other that considers not only the biological, but also and mostly, the psychological dimensions of the individual, with a special emphasis on the issue of difference.

description: We propose an alternative mechanism of baryogenesis in which a scalar baryon undergoes a percolating first-order phase transition in the early Universe. The potential barrier that divides the phases contains explicit B and CP violation and the corresponding instanton that mediates decay is therefore asymmetric. The nucleation and growth of these asymmetric bubbles dynamically generates baryons, which thermalize after percolation; bubble collision dynamics can also add to the asymmetry yield. We present an explicit toy model that undergoes bubble baryogenesis, and numerically study the evolution of the baryon asymmetry through bubble nucleation and growth, bubble collisions, and washout. We discuss more realistic constructions, in which the scalar baryon and its potential arise amongst the color-breaking minima of the MSSM, or in the supersymmetric neutrino seesaw mechanism. Phenomenological consequences, such as gravitational waves, and possible applications to asymmetric dark-matter generation are also discussed.

Bacterial human skin pathogens

description: Probiotic bacteria have been investigated in the prevention and treatment of various diseases and allergies. The current study was undertaken to determine the effect of eight probiotic Lactobacillus species against bacterial human skin pathogens using several techniques. Antimicrobial activity of lactobacilli against Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa and Propionibacterium acnes was evaluated using lactobacilli broth cultures (BCB) and cell free supernatant (CFS). Antimicrobial activity was significantly greater with BCB compared with CFS especially for Lactobacillus plantarum and Lactobacillus acidophilus. Lactobacilli and pathogen aggregation, biofilm formation and adhesion to keratin were assessed. L. casei and L. plantarum were selected for further study as they showed the greatest co-aggregation (18.02 ± 1.34% with L. casei and 14.92 ± 1.45% with L. plantarum) with the pathogens (16.63 ± 1.65% with S. aureus 3761 and 14.58 ± 1.68% with P. aeruginosa) and prevention of biofilm formation by the pathogens. The antimicrobial activity of human beta defensin-2 (hBD-2) alone or with L. plantarum against pathogens was assessed. The results with hBD-2 showed that hBD-2 (10 μg / ml for 5 h) and L. plantarum together were significantly more inhibitory against S. aureus than hBD-2 alone. The presence of NaCl reduced the effectiveness of hBD-2 alone and with L. plantarum. In the presence of L. plantarum, inactivation of mprF and dlt genes led to increased binding of hBD-2 by the bacterial cell wall, and then inhibition growth of bacterial cell wall. Studies investigated the effect of exposure of methicillin resistant Staphylococcus aureus (MRSA) to the supernatant of L. plantarum the susceptibility of MRSA to β-lactams. MRSA became sensitive to β-lactams when treated with culture supernatant of L. plantarum. Gene expression studies demonstrated that the mecR1-mecI-mecA-PBP2 signalling pathway was impeded by exposure to culture supernatant of L. plantarum and β-lactams. The studies reported here demonstrate a possible alternative approach to dealing with skin pathogens, which may have clinical implications especially with regard to MRSA infections, and continued research is advised.

Names, Travelers, Transindividuality: Italo Calvino in the 1970s
Creators: name: Ovan, Sabrina
Publisher: name: Università degli Studi di Milano
Year: 2012
Subjects: Italo Calvino, Oulipo, authorship, collectivity, hyper-novel

description: Situating the novel within the cultural, literary and political milieu of the period, this article provides a reading of Italo Calvino‟s 1979 hypernovel If on a Winter’s Night a Traveler and its relation to the French literary group Oulipo. It analyzes the work‟s link to questions of authorship and collectivity at the core of 1970s literary, philosophical, and political discourse both in Italy and France. In particular, the analysis concentrates on the function of names in the novel as signifiers of individuality and/or collectivity

The Poisson sigma model on closed surfaces

description: Using methods of formal geometry, the Poisson sigma model on a closed surface is studied in perturbation theory. The effective action, as a function on vacua, is shown to have no quantum corrections if the surface is a torus or if the Poisson structure is regular and unimodular (e.g., symplectic). In the case of a Kahler structure or of a trivial Poisson structure, the partition function on the torus is shown to be the Euler characteristic of the target; some evidence is given for this to happen more generally. The methods of formal geometry introduced in this paper might be applicable to other sigma models, at least of the AKSZ type.

The Behaviour of Reproductive Female Little Brown Bats (Myotis lucifugus) in the Albertan Rocky Mountains

description: While there has been substantial work conducted on bat maternity colonies, there is a lack of research on females inhabiting the Rocky Mountains. I collated data from multiple sources and investigated the effect elevation and latitude has on Little Brown bat (Myotis lucifugus) reproductive timing. I conducted research in the Canadian portion of the Rocky Mountains to investigate the effect that colder, wetter nights, and a shorter summer season has on reproduction. I hypothesized that reproductive females would reduce their energy expenditure and/or energy intake would increase, compared to individuals at lower elevations. I studied diet, movement, torpor, and reproductive timings of females in a large (n=700+) maternity colony located around the Kananaskis Lakes in Alberta. To accomplish this, I caught individuals and attached 29 temperature-sensitive radio transmitters to adult females from May to August 2021, noting their reproductive status. I collected fecal samples from individuals and communal roosts for morphological and genetic analysis of prey. I recorded tagged individuals’ presence and skin temperature, and recorded bat box temperatures. Day-roosts were located by following tagged females, and nightly emergence counts were conducted multiple times a week to record changes in colony size. Females used buildings, bat boxes and rock faces for roosts, consistently emerging before sunset and in inclement weather. The majority of females' day roosts were within a 5km range throughout the season, with similar frequencies of roost switching among the various reproductive groups. The estimated gestation time was between 59 and 82 days and longer than the 50-60 average for the species. While there was no significant difference between reproductive stages in the amount of torpor used per day, non-reproductive females spent as much as 99% of the day in torpor (n=11). PCR analysis of guano confirmed consumption of spiders, which has not been confirmed in Alberta previously. These data provide insights into the additional challenges reproductive female Little Brown bats face in the Rocky Mountains and confirm my predictions regarding an extended gestation period, and foraging behaviour. It also highlights the importance of buildings as alternate roosts in the mountains, and their potential in sustaining populations.
Spettri della violenza politica: gli anni Settanta in alcuni romanzi del nuovo millennio

Subjects: Terrorismo, violenza politica, letteratura contemporanea, eversione, spettralità

description: La memoria della violenza politica in Italia resta divisa. Dal punto di vista degli studi sul trauma, si tratterebbe di un trauma collettivo che, non essendo stato elaborato, produce nella memoria collettiva una sorta di spettro, per utilizzare un termine usato da Freud e in seguito da Jacques Derrida nel suo Spectres de Marx (1993). L‘intervento si concentra sulla presenza spettrale della violenza politica in quattro romanzi italiani del nuovo millennio: Tuo figlio (2004) di Gian Mario Villalta, Il segreto (2003) di Geraldina Colotti, La Guerra di Nora (2003) di Antonella Tavassi La Greca, Il sogno cattivo (2006) di Francesca D‘Aloja.

description: We derive a set of hierarchical equations for qubits interacting with a Lorentz-broadened cavity mode at zero temperature, without using the rotating-wave, Born, and Markovian approximations. We use this exact method to reexamine the entanglement dynamics of two qubits interacting with a common bath, which was previously solved only under the rotating-wave and single-excitation approximations. With the exact hierarchy equation method used here, we observe significant differences in the resulting physics, compared to the previous results with various approximations. Double excitations due to counter-rotating-wave terms are also found to have remarkable effects on the dynamics of entanglement.
