description: Cette thèse de maîtrise propose une analyse discursive du stéréotype et de sa participation dans la rupture entre la réalité et la simulation tel qu’il apparaît dans deux romans et une nouvelle québécoises : Kuessipan de Naomi Fontaine, Le pavillon des miroirs de Sergio Kokis et « Base de négociation » de Jean Dion. Ses objectifs principaux sont d’abord la mise en place d’une base théorique alliant la compréhension du stéréotype en tant que phénomène diaphragmatique de Daniel Castillo Durante et les principales théories sur la relation entre le sujet et le réel/la réalité, puis la mise en application de ces théories sur les récits étudiés. Notre cadre théorique comprend l’étude de la relation ontologique de Buber, les recherches sur la simulation et le simulacre de Baudrillard, celle portant sur l’image de Serge Gruzinski ainsi que de multiples études sur le réel, autant d’un point de vue sensoriel (Palo Alto) que social (Guy Debord, Walter Lippmann). Cette thèse veut montrer l’étendue de la mainmise du stéréotype dans le discours des figures de l’« Indienne » et de l’Immigrant pour ensuite présenter les techniques utilisées par les altérités discursives afin de remettre en question ladite mainmise.

description: A closed, orientable, splitting surface in an oriented $3$-manifold is a topologically minimal surface of index $n$ if its associated disk complex is $(n-2)$-connected but not $(n-1)$-connected. A critical surface is a topologically minimal surface of index $2$. In this paper, we use an equivalent combinatorial definition of critical surfaces to construct the first known critical bridge spheres for nontrivial links.

The Regulation of Telomerase Reverse Transcriptase (TERT) by CCAAT/Enhancer Binding Protein β (C/EBPβ) During Skeletal Muscle Differentiation

description: Our lab has identified the bZIP transcription factor CCAAT/Enhancer Binding Protein beta (C/EBPβ) as a negative regulator of myogenic differentiation. C/EBPβ is highly expressed in satellite cells and is downregulated during myogenic differentiation, a step that is critical for terminal differentiation, as ectopic C/EBPβ expression blocks this process. Telomerase has been identified as a C/EBPβ target gene in liver and other systems, and has been implicated in the regulation of muscle regenerative responses in models of Duchenne Muscular Dystrophy. Given that C/EBPβ is overexpressed in models of muscle wasting, and high levels of telomerase inhibit differentiation, I hypothesized that C/EBPβ inhibits myogenic differentiation through upregulation of TERT (telomerase reverse transcriptase) expression. I demonstrate that overexpression of C/EBPβ in myoblasts increases mTERT expression under both growth and differentiation conditions. Conversely, loss of C/EBPβ expression in myoblasts using shRNA technology or after isolation of primary myoblasts from conditional knockout mice, results in a downregulation of TERT expression and activity. When TERT was pharmacologically inhibited or knocked down using a shRNA, there was a significant improvement in differentiation and fusion in C2C12 myoblasts overexpressing C/EBPβ as evidenced by an increase in the number of MHC+ fibers and expression of muscle-specific differentiation genes. Interestingly, I found that C/EBPβ and TERT expression were increased in both embryonic and alveolar models of rhabdomyosarcoma. In response to this, a knockdown of C/EBPβ in rhabdomyosarcoma cells decreased TERT expression and activity, and enhanced differentiation but not fusion in a model of embryonic rhabdomyosarcoma. These findings illustrate the novel regulation of TERT in skeletal muscle by C/EBPβ, and reveal C/EBPβ as an attractive therapeutic target for the treatment of muscle diseases such as rhabdomyosarcoma.
Non-linear non-local molecular electrodynamics with nano-optical fields

description: The interaction of optical fields sculpted on the nano-scale with matter may not be described by the dipole approximation since the fields vary appreciably across the molecular length scale. Rather than incrementally adding higher multipoles it is advantageous and more physically transparent to describe the optical process using non-local response functions that intrinsically include all multipoles. We present a semi-classical approach to the non-linear response functions based on the minimal coupling Hamiltonian. The first, second and third order non-local response functions are expressed in terms of correlation functions of the charge and the current densities. This approach is based on the gauge invariant current rather than the polarization, and on the vector potential rather than the electric and magnetic fields.

Impact of patient and partner insight into anorexia nervosa on treatment outcome
Creators: name: Pentel, Kimberly
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Across disorders, increased insight is associated with better treatment outcome. Among patients with AN, limited insight is common yet understudied, and romantic partners develop their own understanding of the disorder. In this study, an observational coding system was developed to assess patient and partner insight into AN. Coders assessed pre-treatment couple conversations for 22 couples in which one individual had AN. Codes were used to predict patient outcome following cognitive-behavioral couple-based AN treatment. The proposed model posited that increased insight would predict better patient outcomes, mediated by relationship functioning. Results indicated that increased insight was associated with lower end-treatment patient symptom severity. Strikingly, partner insight predicted patient’s outcome better than the patient’s own insight. However, relationship functioning did not mediate the association between insight and outcome. These pilot findings underscore the pivotal role of partners in the recovery process and suggest that harnessing partner insight may help maximize treatment gains.
Photon-phonon parametric oscillation induced by the quadratic coupling in an optomechanical resonator

description: A direct photon-phonon parametric effect of the quadratic coupling on the mean-field dynamics of an optomechanical resonator in the large-scale-movement regime is found and investigated. Under a weak pumping power, the mechanical resonator damps to steady state with a nonlinear static response sensitively modified by the quadratic coupling. When the driving powerincreases beyond the static energy balance, the steady states lose their stabilities via Hopf bifurcations and the resonator produces stable self-sustained oscillation(limit-circle behavior) of discrete energies with step-like amplitudes due to the parametric effect of the quadratic coupling, which can be understood roughly by the power balance between gain and loss on the resonator. A further increase of the pumping power can induce chaotic dynamic of the resonator via a typical routine of period-doubling bifurcation but which can be stabilized by the parametric effect through an inversion bifurcation process back to limit-circle states. The bifurcation-to-inverse-bifurcation transitions are numerically verified by the maximal Lyapunov exponents of the dynamics and which indicate an efficient way to suppress the chaotic behavior of the optomechanical resonator by the quadratic coupling. Furthermore, the parametric effect of the quadratic coupling on the dynamic transitions of an optomechanical resonator can be conveniently detected or traced by the output power spectrum of the cavity field.

Risks of consociationalism in Sudan
Creators: name: Saltzman, Jeffrey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Sudan's Comprehensive Peace Agreement (CPA) is flawed and representative of many weaknesses of consociationalism. The CPA misunderstands the root causes of conflict in Sudan, oversimplifying Sudanese history to a conflict between particular groups in its Arab north and African south. In the CPA's efforts to mitigate the grounds for future conflict between the north and south, it divides the new Sudanese state largely between those groups. However, Sudan is much more complicated than the CPA suggests. The country is much better conceived as a scattering of peripheral regions, groups from which have recurrently battled the central state for fairer shares of public resources. These grievances motivate ongoing violence in western and eastern Sudan, where armed groups rebel against their marginalization from the CPA's state institutions; those grievances can be observed today within parts of the north and south, too. I conclude with recommendations for how the CPA should be amended.

description: (1) The field of synthetic biology is rapidly growing, empowered by advancements in Molecular Biology. To express genes of interest, scientists exploit plasmids engineered for bacterial or mammalian expression. Existing plasmids carry superfluous DNA that decreases transformation and transfection efficiencies. Here, we present a novel set of mammalian expression vectors with different selection markers and tunable expression levels. Despite being substantially smaller than traditional vectors, these minimized plasmids display similar levels of gene expression.This set of novel mammalian expression vectors should be useful for a broad range of modern applications. (2) DREAM is a mammalian calcium-dependent repressor of gene expression, which binds to a downstream DNA sequence, called DRE. The DREAM/DRE system offers a unique way of linking gene expression to calcium influx (44), but the utility of this system has not been assessed in bacteria. Here we develop a simple bacterial cell growth assay, where cell growth is prevented by the expression of SacB. This cell growth assay is then exploited to assess the utility of the DREAM/DRE system in bacteria. Unexpectedly, the DRE sequence by itself represses the expression of SacB, which can then be de-repressed by the co-expression of DREAM. Should this recovery of SacB expression maintain calcium-dependence, the DREAM/DRE system could be exploited in future directed strategies to evolve calcium-permeable ion channels.

An Experimental and Mathematical Study on the Prolonged Residence Time of a Sphere Falling Through Stratified Fluids at Low Reynolds Number
Creators: name: Lin, Joyce T.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: A sphere falling through a stable stratification of miscible fluids exhibits a prolonged settling rate due to the deformation of the fluid density field. A detailed experimental study is presented in which time-lapse images are analyzed to find the sphere and fluid interface positions. We additionally quantify the effect of the enhanced residence time through a settling-rate competition between spheres in homogeneous and stratified fluids. Various aspects of the experiments, such as convection, diffusion, and internal waves, are studied extensively. We use a Green's function formulation to derive from first principles a numerically assisted theoretical model for the behavior of the sphere and the surrounding fluid at low Reynolds number. This model is verified in a comparative study with experimental results from a wide range of parameters. Analysis of the theoretical model provides the streamlines and instantaneous stagnation points, affording some insight into the behavior of the interior of the fluid. The nondimensional form of the model is used to characterize the entire flow with only four parameters, and the impact of each of these parameters on the flow is studied numerically. With a model that shows good agreement with experimental data, we can then extend the theory to free space. In this regime, the formulation is exact, rather than an asymptotic approximation. We also discuss the convergence of volume integrals of the model in light of the Stokes paradox, in which a sphere in homogeneous fluid will drag an infinite volume. The model can be further pressed into a higher Reynolds number regime, which we then compare with experimental data. A brief look is taken at the extension to many-body sedimentation in which the similarities to a single settling sphere are noted. Additionally, we can approximate a linear stratification and find fairly good agreement.
Boson peak and Ioffe-Regel criterion in amorphous silicon-like materials: the effect of bond directionality

description: The vibrational properties of model amorphous materials are studied by combining complete analysis of the vibration modes, dynamical structure factor and energy diffusivity with exact diagonalization of the dynamical matrix and the Kernel Polynomial Method which allows a study of very large system sizes. Different materials are studied that differ only by the bending rigidity of the interactions in a Stillinger-Weber modelization used to describe amorphous silicon. The local bending rigidity can thus be used as a control parameter, to tune the sound velocity together with local bonds directionality. It is shown that for all the systems studied, the upper limit of the Boson peak corresponds to the Ioffe-Regel criterion for transverse waves, as well as to a minimum of the diffusivity. The Boson peak is followed by a diffusivity's increase supported by longitudinal phonons. The Ioffe-Regel criterion for transverse waves corresponds to a common characteristic mean-free path of 5-7 Å (which is slightly bigger for longitudinal phonons), while the fine structure of the vibrational density of states is shown to be sensitive to the local bending rigidity.

description: Via large and small $N_c$ relations we derive nonperturbative results about the conformal window of two-index theories. Using Schwinger-Dyson methods as well as four-loops results we estimate subleading corrections and show that naive large number of colors extrapolations are unreliable when $N_c$ is less than about six. Nevertheless useful nonperturbative inequalities for the size of the conformal windows, for any number of colors, can be derived. By further observing that the adjoint conformal window is independent of the number of colors we argue, among other things, that: The large $N_c$ two-index conformal window is twice the conformal window of the adjoint representation (which can be determined at small $N_c$) expressed in terms of Dirac fermions; Lattice results for adjoint matter can be used to provide independent information on the conformal dynamics of two-index theories such as SU($N_c$) with two and four symmetric Dirac flavors.

description: We present theoretical studies of high-order harmonic generation (HHG) driven by plasmonic fields in two-electron atomic systems. Comparing the two-active electron and single-active electron approximation models of the negative hydrogen ion atom, we provide strong evidence that a double non-sequential two-electron recombination appears to be the main responsible for the HHG cutoff extension. Our analysis is carried out by means of a reduced one-dimensional numerical integration of the two-electron time-dependent Schrödinger equation (TDSE), and on investigations of the classical electron trajectories resulting from the Newton's equation of motion. Additional comparisons between the negative hydrogen ion and the helium atom suggest that the double recombination process depends distinctly on the atomic target. Our research paves the way to the understanding of strong field processes in multi-electronic systems driven by spatially inhomogeneous fields.

Natural classical limit for the center of mass of many-particle quantum systems

Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Physics (quant-ph)

description: We discuss the conditions for the classicality of quantum states with a very large number of identical particles. By treating the center of mass as a Bohmian particle, we show that it follows a classical trajectory when the distribution of the Bohmian positions in just one experiment is always equal to the marginal distribution of the quantum state in physical space. This result can also be interpreted as a unique-experiment generalization of the well-known Ehrenfest theorem. We also demonstrate that the classical trajectory of the center of mass is fully compatible with a conditional wave function solution of a classical non-linear Schrödinger equation. Our work shows clear evidence for a quantum-classical inter-theory unification and opens new possibilities for practical quantum computations with decoherence.

Visual and Quantitative Assessment of Poincaré Plots to Predict Mortality in Critically Ill Children

Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Heart rate variability (HRV) can be used as a noninvasive indicator of autonomic function.1-4 Diminished or ectopic heart rate variability is associated with increased mortality in a variety of diseases in adult and pediatric patients.5-9 Poincaré plots represent a non-linear method for visually displaying HRV. Poincaré plots are derived by graphing each normal RR interval (ms) against the subsequent RR interval. In healthy individuals, Poincaré plots take on a Comet-shaped pattern, which arises from the normal decrease in variability as heart rate slows.10 In adults with advanced heart failure the plots are either Torpedo shaped, reflecting minimal variability within RR intervals; Fan shaped, reflecting diminished variability within RR intervals; or Complex shaped, reflecting random variability within RR intervals.10 The present study aimed to determine whether resident physicians could predict whether critically ill children hospitalized in a Pediatric Intensive Care Unit (PICU) survived to discharge based on the interpretation of Poincaré plots.

description: Unicast IPTV services that can support live TV, video-on-demand (VoD), video conferencing, and online gaming applications over broadband wireless cellular networks have been becoming popular in recent years. However, video streaming services significantly impact the performance of wireless cellular networks because they are bandwidth hogs. To maintain the system performance, effective admission control and resource allocation mechanisms based on an accurate mathematical analysis are required. On the other hand, the quality of a wireless link usually changes with time due to the user mobility or time-varying channel characteristics. To counteract such time-varying channels and improve the spectral efficiency, adaptive modulation and coding (AMC) scheme can be adopted in offering unicast IPTV services for mobile users. In this paper, closed-form solutions for the bandwidth usage, blocking rate, and dropping rate of unicast IPTV services over wireless cellular networks were derived based on the novel queueing model that considers both user mobility and AMC. Simulations were also conducted to validate the accuracy of analytical results. Numerical results demonstrate that the presented analytical results are accurate. Based on the accurate closed-form solutions, network providers can implement precise admission control and resource allocation for their networks to enhance the system performance.

description: An ideal plasma lens can provide the focusing power of a small f-number, solid-state focusing optic at a fraction of the diameter. An ideal plasma lens, however, relies on a steady-state, linear laser pulse-plasma interaction. Ultrashort multi-petawatt (MPW) pulses possess broad bandwidths and extreme intensities, and, as a result, their interaction with the plasma lens is neither steady state nor linear. Here we examine nonlinear and time-dependent modifications to plasma lens focusing, and show that these result in chromatic and phase aberrations and amplitude distortion. We find that a plasma lens can provide enhanced focusing for 30 fs pulses with peak power up to ~1 PW. The performance degrades through the MPW regime, until finally a focusing penalty is incurred at ~10 PW.

description: The stationary distribution of a fully chaotic system typically exhibits a fractal structure, which dramatically changes if the dynamical equations are even slightly modified. Perturbative techniques are not expected to work in this situation. In contrast, the presence of additive noise smooths out the stationary distribution, and perturbation theory becomes applicable. We show that a perturbation expansion for the Fokker-Planck evolution operator yields surprisingly accurate estimates of long-time averages in an otherwise unlikely scenario.

Interpreting Historic Site Narratives: Duke Homestead on Tour

Year: 2016

description: This thesis uses Duke Homestead State Historic Site and Tobacco Museum as an ethnographic case study to explore a new vocabulary for understanding the power, politics, and production of historical narratives as communicated on guided walking tours. By examining narratives as they fluctuate along an arc from the scripted, the spoken, and the received, I discuss moments of sense-making, discomfort, and disconnect as they occur on the historic site. I focus on the tours’ inclusion, exclusion, and negotiation of Caroline, a young girl who was owned and enslaved by Washington Duke, through which societal expectations of history can be examined in relation to the desires and goals of those who wrote the tour script. Her story offers an example of narrative discomfort, negotiated through hesitation, elision, and derision within the spoken presentation . Many voices contribute to the construction and perpetuation of historical narratives, and this thesis uses the voices of site employees, interns, volunteers, and visitors to understand the dynamism of place-based history.

description: We discuss with a rather critical eye the current situation of black hole (BH) solutions in $f(R)$ gravity and shed light about its geometrical and physical significance. We also argue about the meaning, existence or lack thereof of a Birkhoff's theorem in this kind of modified gravity. We focus then on the analysis and quest of $non-trivial$ (i.e. hairy) $asymptotically\,\,flat$ (AF) BH solutions in static and spherically symmetric (SSS) spacetimes in vacuum having the property that the Ricci scalar does $not$ vanish identically in the domain of outer communication. To do so, we provide and enforce the $regularity\,\,conditions$ at the horizon in order to prevent the presence of singular solutions there. Specifically, we consider several classes of $f(R)$ models like those proposed recently for explaining the accelerated expansion in the universe and which have been thoroughly tested in several physical scenarios. Finally, we report analytical and numerical evidence about the $absence$ of $geometric\,\,hair$ in AFSSSBH solutions in those $f(R)$ models. First, we submit the models to the available no-hair theorems, and in the cases where the theorems apply, the absence of hair is demonstrated analytically. In the cases where the theorems do not apply, we resort to a numerical analysis due to the complexity of the non-linear differential equations. Within that aim, a code to solve the equations numerically was built and tested using well know exact solutions. In a future investigation we plan to analyze the problem of hair in De Sitter and Anti-De Sitter backgrounds.

Imagining Roman-ness: a study of the theater reliefs at Sabratha

Year: 2007

description: Meticulously restored by Italian archaeologists in the 1930s, the Roman theater at Sabratha in Libya is today one of the most impressive Roman monuments in North Africa. The Sabratha theater is distinctive for its sculptured pulpitum, which is decorated with a variety of mythological, historical, and genre scenes. This paper examines the sculptural decoration of the theater within the historical and social context of the development of Sabratha, examining both the style and content of the program of decoration. The application of ‘Romanization’ in Sabratha will be examined in view of the sculptural decoration as material evidence of the presence and effects of Empire on the provincial city. The Sabratha reliefs and the theater building originally functioned in part to form the face of Sabratha as a ‘Roman’ city.

description: We report a new detection of neutral deuterium in the sub Damped Lyman Alpha system with low metallicity [O/H]\,=\,$-2.042 \pm 0.005$ at $z_{\rm abs}=2.437$ towards QSO~J\,1444$+$2919. The hydrogen column density in this system is log$N$(H\,{\sc i})~$=19.983\pm0.010$ and the measured value of deuterium abundance is log(D/H)~$=-4.706\pm0.007_{\rm stat}\pm0.067_{\rm syst}$. This system meets the set of strict selection criteria stated recently by Cooke et al. and, therefore, widens the {\it Precision Sample} of D/H. However, possible underestimation of systematic errors can bring bias into the mean D/H value (especially if use a weighted mean). Hence, it might be reasonable to relax these selection criteria and, thus, increase the number of acceptable absorption systems with measured D/H values. In addition, an unweighted mean value might be more appropriate to describe the primordial deuterium abundance. The unweighted mean value of the whole D/H data sample available to date (15 measurements) gives a conservative value of the primordial deuterium abundance (D/H)$_{\rm p}=(2.55\pm 0.19)\times10^{-5}$ which is in good agreement with the prediction of analysis of the cosmic microwave background radiation for the standard Big Bang nucleosynthesis. By means of the derived (D/H)$_{\rm p}$ value the baryon density of the Universe $Ω_{\rm b}h^2=0.0222\pm0.0013$ and the baryon-to-photon ratio $η_{10} = 6.09\pm 0.36$ have been deduced. These values have confident intervals which are less stringent than that obtained for the {\it Precision Sample} and, thus, leave a broader window for new physics. The latter is particularly important in the light of the lithium problem.

description: Combs are a simple caricature of various types of natural branched structures, which belong to the category of loopless graphs and consist of a backbone and branches. We study continuous time random walks on combs and present a generic method to obtain their transport properties. The random walk along the branches may be biased, and we account for the effect of the branches by renormalizing the waiting time probability distribution function for the motion along the backbone. We analyze the overall diffusion properties along the backbone and find normal diffusion, anomalous diffusion, and stochastic localization (diffusion failure), respectively, depending on the characteristics of the continuous time random walk along the branches.

description: Chronic rhinosinusitis with nasal polyps (CRSwNP) has a high recurrence rate after surgery despite the availability of medical treatments. Multiple clinical and biological factors have been associated with poor post-operative outcomes in patients with CRSwNP. However, these factors and their prognostic values have not yet been extensively summarized. This systematic review included 49 cohort studies exploring the prognostic factors for post-operative outcomes in CRSwNP. A total of 7802 subjects and 174 factors were included. All investigated factors were classified into three categories according to their predictive value and evidence quality, of which 26 factors were considered plausible for post-operative outcome prediction. Previous nasal surgery, ethmoid-to-maxillary (E/M) ratio, fractional exhaled nitric oxide, tissue eosinophil count or percentage, tissue neutrophil count, tissue IL-5, tissue eosinophil cationic protein, and CLC or IgE in nasal secretion provided more reliable information for prognosis in at least two studies. Exploring predictors through noninvasive or minimally invasive methods for specimen collection is recommended for future work. Models combining multiple factors must be established, as no single factor is effective for the whole population.
Characterization of Listeria monocytogenes operon Required for Stress Resistance and Virulence

description: Environmental microbes must often cope with variations encountered in physicochemical conditions, including temperature, UV light exposure, nutrient availability, oxygen tension, and osmolarity. One mechanism used by bacteria to respond to environmental changes relies on cell signaling mediated by two-component signaling systems (TCSs), which are able to translate rapid environmental changes into regulatory readouts. Listeria monocytogenes (Lm) is a gram-positive foodborne pathogen that is ubiquitous in the environment and can switch to infect mammalian hosts through the ingestion of contaminated food. PieRS is a two-component signaling system Lm uses to resist ethanol exposure as well as regulate the chaperones PrsA1, PrsA2, and the serine protease chaperone HtrA. PieRS regulates the expression of additional gene products that have not been described but may be associated with roles in stress conditions and virulence. In this dissertation work, we describe studies focused on plasmid insertion inactivation of the PieRS-regulated genes lmo1505/1506, lmo0442, and lmo0881, indicating specific roles for each regulon in resistance to stress conditions. Furthermore, we describe studies focused on in-frame deletion mutants of these regulon members to define individual gene contributions to stress conditions relevant for Lm colonization of the gastrointestinal tract or within the environment. Analysis of an intragastric mouse model of infection suggests that Lmo0442 and Lmo0881 have roles in promoting bacteria colonization of the gastrointestinal tract during Lm infection. Additionally, Lmo0442 was shown to have a role in adhesion during the infection of colonic epithelial cell lines. In the case of Lmo1505, experimental data suggested it may play a role in resistance to ethanol stress, a condition that could be relevant to GI colonization as well as in stress resistance associated with food industry production. A closer look at the PieRS regulon Lmo0881 confirms that this protein is secreted into the supernatant of Lm cultures and could be functional as a multimer. All the data present in this dissertation moves our knowledge on the field one step forward regarding how the two-component signaling system in Lm works together with multiple gene products to give an advantage to Lm to survive stress conditions and promote successful infection to the host.
Le Silence de la Guerre? French Combatants' Memoirs of the Algerian War, 1954-1988

description: Fifty years after the cessation of hostilities, the memory of the Algerian War of Independence (1954-1962) remains an open wound in French society. From the time of the war itself, French veterans of Algeria sought to find their voice in a society largely indifferent to them and their experiences. This thesis examines the evolving memory of the Algerian War among French veterans who wrote wartime memoirs, and seeks the relationship of these narratives with the wider French collective memory of the Algerian War, by closely following the constructed figure of the combatant. This study finds that French veterans' narratives of Algeria, while all expressing various kinds of victimhood, evolved in time from the political to the personal, encouraged by governmental amnesties that depoliticized the memory of the war and contributed to the impossibility of a general collective memory of the Algerian War in France.

description: Isotope shifts of transition frequencies in atoms constrain generic long- and intermediate-range interactions. We focus on new physics scenarios that can be most strongly constrained by King Linearity Violation such as models with B-L vector bosons, Higgs portal and chameleon. With the anticipated precision, King Linearity Violation has the potential to set the strongest laboratory bounds on these models in some regions of parameter space. Furthermore, we show that this method can probe the couplings relevant for the protophobic interpretation of the recently reported Be anomaly. We extend the formalism to include an arbitrary number of transitions and isotope pairs and fit the new physics coupling to the currently available isotope shift measurements.

description: Explosive Percolation describes the abrupt onset of large-scale connectivity that results from a simple random process designed to delay the onset of the transition on an underlying random network or lattice. Explosive percolation transitions exhibit an array of novel universality classes and supercritical behaviors including a stochastic sequence of discontinuous transitions, multiple giant components, and lack of self-averaging. Many mechanisms that give rise to explosive percolation have been discovered, including overtaking, correlated percolation, and evolution on hierarchical lattices. Many connections to real-world systems, ranging from social networks to nanotubes, have been identified and explosive percolation is an emerging paradigm for modeling these systems as well as the consequences of small interventions intended to delay phase transitions. This review aims to synthesize existing results on explosive percolation and to identify fruitful directions for future research.
