description: We report on the synthesis of complex lead-free perovskite-type (1-x)(Ba$_{0.8}$Ca$_{0.2}$)TiO$_3$-xBi(Mg$_{0.75}$W$_{0.25}$)O$_3$ (BCT-xBMW) and (1-x)(Ba$_{0.8}$Ca$_{0.2}$)TiO$_3$-xBi(Mg$_{0.75}$Mo$_{0.25}$)O$_3$ (BCT-xBMM) solid solutions via conventional solid-state reaction route. The sintering temperature was adjusted as a function of composition x to obtain dense samples (relative densities over 95%) at the same time minimizing bismuth evaporation. X-ray diffraction analysis shows formation of single-phase perovskites for $0 \le x \le 0.10$ in the BCT-xBMW series and increasing concentrations of impurity phases for $x \ge 0.15$ and for $x \ge 0.05$ in BCT-xBMM. A transition from a tetragonal to pseudo-cubic perovskite structure is observed in BCT-xBMW and BCT-xBMM at $x = 0.05$. The dielectric response has been characterized between -60 $^\circ$C and 300 $^\circ$C for BCT-xBMW, and between 30 $^\circ$C and 300 $^\circ$C for BCT-xBMM using impedance spectroscopy, showing a transition from ferroelectric to relaxor-like behavior at $x \ge 0.05$. Additional polarization and Raman spectroscopy measurements reveal the occurrence of highly disordered systems. Analysis of the Raman spectra indicates structural phase changes and lattice modifications caused by chemical substitution. For the composition 0.8Ba$_{0.8}$Ca$_{0.2}$TiO$_3$-0.2Bi(Mg$_{0.75}$W$_{0.25}$)O$_3$ a temperature-stable permittivity of about 600 ($\pm 15$% between 60 $^\circ$C and 300 $^\circ$C) and small losses of $\tanδ< 0.02$ for $T \le 230$ $^\circ$C at 1 kHz are observed, making it a suitable dielectric material for high temperature capacitors.

description: These are the transcriptions of "a talk describing the theoretical insights of those honored (and the one who wasn't) and how this has led to all the physics we have been doing over the last couple of decades." After prologue, we first deal with Nambu's insight on Spontaneous Symmetry Breaking, which is rooted in an analogy with the BCS theory of superconductivity. The insight resonates to this day, as we await the LHC era to dawn. The second half starts from Gell-Mann--Lévy--Cabibbo theory, through the GIM mechanism that completed the $2\times 2$ rotations, to the insight of Kobayashi and Maskawa that CP violation could arise from the charged currents, if there exists a 3rd generation of quarks. The richness that followed defines this (FPCP) conference. We end with a perspective on a (possible) redux with a 4th generation of quarks.

description: Negative thermal expansion (NTE) materials possess a low-density, open structure which can respond to high pressure conditions, leading to new compounds and/or different physical properties. Here we report that one such NTE material -- white, insulating, orthorhombic Sc2W3O12 -- transforms into a black compound when treated at 4 GPa and 1400 oC. The high pressure phase, Sc0.67WO4, crystallizes in a defect-rich wolframite-type structure, a dense, monoclinic structure (space group P2/c) containing 1-D chains of edge-sharing WO6 octahedra. The chemical bonding of Sc0.67WO4 vis-a-vis the ambient pressure Sc2W3O12 phase can be understood on the basis of the Sc defect structure. Magnetic susceptibility, resistivity, thermoelectric power and IR spectroscopic measurements reveal that Sc0.67WO4 is a paramagnet whose conductivity is that of a metal in the presence of weak localization and electron-electron interactions. Oxygen vacancies are suggested as a potential mechanism for generating the carriers in this defective wolframite material.

description: Two-mode squeezed states are scalable and robust entanglement resources for continuous-variable and hybrid quantum information protocols at a distance. We consider the effect of a linear cross talk in the multimode distribution of two-mode squeezed states propagating through parallel similar channels. First, to reduce degradation of the distributed Gaussian entanglement, we show that the initial two-mode squeezing entering the channel should be optimized already in the presence of a small cross talk. Second, we suggest simultaneous optimization of relative phase between the modes and their linear coupling on a receiver side prior to the use of entanglement, which can fully compensate the cross talk once the channel transmittance is the same for all the modes. For the realistic channels with similar transmittance values for either of the modes, the cross talk can be still largely compensated. This method relying on the mode interference overcomes an alternative method of entanglement localization in one pair of modes using measurement on another pair and feed-forward control. Our theoretical results pave the way to more efficient use of multimode continuous-variable photonic entanglement in scalable quantum networks with cross talk.

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Estimating a 3D human pose has proven to be a challenging task, primarily because of the complexity of the human body joints, occlusions, and variability in lighting conditions. In this paper, we introduce a higher-order graph convolutional framework with initial residual connections for 2D-to-3D pose estimation. Using multi-hop neighborhoods for node feature aggregation, our model is able to capture the long-range dependencies between body joints. Moreover, our approach leverages residual connections, which are integrated by design in our network architecture, ensuring that the learned feature representations retain important information from the initial features of the input layer as the network depth increases. Experiments and ablations studies conducted on two standard benchmarks demonstrate the effectiveness of our model, achieving superior performance over strong baseline methods for 3D human pose estimation.

description: The subject of this research, the medicalization of the gendered body, is a shifting object. It has changed its medical name from Intersex to DSD (Disorders -or Divergence- of Sex Development), since the beginning of this research project. Loosely speaking it addresses the gendered components of the body, and their subsequent consideration. Drawing closer, it addresses how modern medicine treats people who manifest variations of one of the gendered components of the body, inserting their bodies into pathological categories now called DSD. This shifting terrain of different modes of viewing the gendered body has grown to include many variations, no longer solely interested in the mythical hermaphrodite. The locus of this investigation is in the interaction between these patient groups and doctors in Italy.

Per la prima volta in Italia, si fa il punto sulla natura, la storia, le rappresentazioni di questa condizione, si esamina il corpo di genere (gendered body), la sua medicalizzazione, s’indaga l’autopercezione dei soggetti in questione.

In this model, we investigate curvatures and the generalized Kretschmann invariant which plays a crucial role for singularities. In addition, the derived path equations are used for the gravitational redshift of the SFR-model and these are compared with the GR model. Finally, we get some results for different values of parameters of the generalized photonsphere of the SFR-model and we find small deviations from the classical results of general relativity (GR) which may be ought to the possible Lorentz violation effects.

description: In this PhD thesis the crashworthiness topic is studied with the perspective of the development of a small-scale experimental test able to characterize a material in terms of energy absorption. The material properties obtained are then used to validate a nu- merical model of the experimental test itself.
Consequently, the numerical model, calibrated on the specific ma- terial, can be extended to more complex structures and used to simulate their energy absorption behavior. The experimental activity started at University of Washington in Seattle, WA (USA) and continued at Second Faculty of Engi- neering, University of Bologna, Forl`ı (Italy), where the numerical model for the simulation of the experimental test was implemented and optimized.
Sleep-related changes in blood pressure in hypocretin-deficient narcoleptic mice
Creators: name: Bastianini, Stefano <1983>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2011
Subjects: BIO/09 Fisiologia

description: Objectives. Blood pressure (BP) physiologically has higher and lower values during the active and rest period, respectively. Subjects failing to show the appropriate BP decrease (10-20%) on passing form diurnal activity to nocturnal rest and sleep have increased risk of target organ damage at the cardiac, vascular and cerebrovascular levels.
Hypocretin (HCRT) releasing neurons, mainly located in the lateral hypothalamus, project widely to the central nervous system. Thus HCRT neurons are involved in several autonomic functions, including BP regulation. HCRT neurons also play a key role in wake-sleep cycle regulation, the lack of which becomes evident in HCRT-deficient narcoleptic patients.
I investigated whether chronic lack of HCRT signaling alters BP during sleep in mouse models of narcolepsy.
Methods. The main study was performed on HCRT-ataxin3 transgenic mice (TG) with selective post-natal ablation of HCRT neurons, HCRT gene knockout mice (KO) with preserved HCRT neurons, and Wild-Type control mice (WT) with identical genetic background. Experiments where replicated on TG and WT mice with hybrid genetic background (hTG and hWT, respectively). 
Mice were implanted with a telemetric pressure transducer (TA11PA-C10, DSI) and electrodes for discriminating wakefulness (W), rapid-eye-movement sleep (REMS) and non-REMS (NREMS). Signals were recorded for 3 days. Mean BP values were computed in each wake-sleep state and analyzed by ANOVA and t-test with significance at p<0.05.
Results. The decrease in BP between either NREMS or REMS and W was significantly blunted in TG and KO with respect to WT as well as in hTG with respect to hWT.
Conclusions. Independently from the genetic background, chronic HCRT deficiency leads to a decreased BP difference between W and sleep potentially adverse in narcoleptic subjects. These data suggest that HCRT play an important role in the sleep-dependent cardiovascular control.

description: The recent reform in European antitrust enforcement is embodied in Regolation n. 1/2003/
Ce and related Communications. Since 2004 when it came into force, some crytical
assessments can already be made. The work starts from some technical analysis of the
reform, under a procedural perspective, to assess the proceedings’ real impact on parties’
rights and to criticize its limits. Decentralisation has brought about more complicacies,
since community procedural systems are not harmonized, neither in their administrative
rules, nor in their civil proceedings, which are all involved in the European antitrust
network. Therefore, antitrust proceedings end un as being more jurisdictional in their
effects than in their guarentees, which is a flaw to be mended by legislators. National laws
shoud be harmonized, community law should be clarified and the system should turn more
honestly towards a rationalized jurisdiction-cented mechanism. Otherwise, parties defense
rights and the overall efficiency are put into doubt. Italy is a good exemple of how many
colmlicacies can outburst from national procedures and national decentralised application.
An uncertain pattern of judicial control, together with unclear relationships among the
institutions to cooperate in the antitrust network can produce more problems than they aim
to solve. As to the private enforcement, Regulation n.1 does not even attempt to give
precise regulation to this underdeveloped sector. A continual comparison with U.S. system
has brought the Commission to become aware both of the risks and of the advanteges of
an increased civil antitrust litigation in fronto of national judges. In order to substain a
larger development of this parallel and, presently, difficult way of judicial compensation, it
is presently ongoing a consultation among states to find suitable incentives to make
private enforcement more appealing and effective. The solution to this lack of private
litigation is not to be sought in Regulation n. 1 which calls into action national legislators
and proceedures to implement further improvements. As a conclusion, Regulation n. 1 is
the outpost of an ambitious community design to create an efficient control mechanism
over antitrust violations. It focuses on Commission proceedings, powers and sanctions in
order to establish deterrence, then it highlights civil litigation perspectives and it involves
directly states into antitrust application. It seems that more could be done to technically
shape administrative proceedings in a more jurisdictionally oriented form, then to clarify
respective roles and coordination mecanisms in order to prevent difficulties easy to forsee.
Some of jurisprudential suggestions have been accepted, but much more is left to be done
in the future to improve european antitrust enforcement system.
Revisiting a detached stellar structure in the outer northeastern region of the Small Magellanic Cloud

description: The outer northeastern region of the Small Magellanic Cloud (SMC) is populated by a shell-like overdensity whose nature was recently investigated. We analyzed twenty catalogued star clusters projected onto it from Survey of the MAgellanic Stellar History data sets. After carrying out a cleaning of field stars in the star cluster colour-magnitude diagrams (CMDs), and deriving their astrophysical properties from the comparison between the observed and synthetic CMDs, we found that four objects are not genuine star clusters, while the remaining ones are young star clusters (11, age $\sim$ 30-200 Myr) and intermediate-age (5, age $\sim$ 1.7-2.8 Gyr) star clusters, respectively. The resulting distances show that intermediate-age and some young star clusters belong to the SMC main body, while the remaining young star clusters are nearly 13.0 kpc far away from those in the SMC, revealing that the shell-like overdensity is more extended along the line-of-sight than previously thought. We also found a clear age trend and a blurred metallicity correlation along the line-of-sight of young clusters, in the sense that the farther a star cluster from the SMC, the younger, the more metal rich, and the less massive it is. These young clusters are also affected by a slightly larger interstellar reddening than the older ones in the shell-like overdensity. These outcomes suggest that the shell-like overdensity can possibly be another tidally perturbed/formed SMC stellar structure from gas striped off its body, caused by the interaction with the Large Magellanic Cloud or the Milky Way.

description: Employing a recently developed Monte Carlo model, we study the fission of 240Pu induced by neutrons with energies from thermal to just below the threshold for second chance fission. Current measurements of the mean number of prompt neutrons emitted in fission, together with less accurate measurements of the neutron energy spectra, place remarkably fine constraints on predictions of microscopic calculations. In particular, the total excitation energy of the nascent fragments must be specified to within 1 MeV to avoid disagreement with measurements of the mean neutron multiplicity. The combination of the Monte Carlo fission model with a statistical likelihood analysis also presents a powerful tool for the evaluation of fission neutron data. Of particular importance is the fission spectrum, which plays a key role in determining reactor criticality. We show that our approach can be used to develop an estimate of the fission spectrum with uncertainties several times smaller than current experimental uncertainties for outgoing neutron energies up to 2 MeV.

Triggering recollisions with XUV pulses: Imprint of recolliding periodic orbits

Year: 2021
Subjects: subject: Atomic Physics (physics.atom-ph)

description: We consider an electron in an atom driven by an infrared (IR) elliptically polarized laser field after its ionization by an ultrashort extreme ultraviolet (XUV) pulse. We find that, regardless of the atom species and the laser ellipticity, there exists XUV parameters for which the electron returns to its parent ion after ionizing, i.e., undergoes a recollision. This shows that XUV pulses trigger efficiently recollisions in atoms regardless of the ellipticity of the IR field. The XUV parameters for which the electron undergoes a recollision are obtained by studying the location of recolliding periodic orbits (RPOs) in phase space. The RPOs and their linear stability are followed and analyzed as a function of the intensity and ellipticity of the IR field. We determine the relation between the RPOs identified here and the ones found in the literature and used to interpret other types of highly nonlinear phenomena for low elliptically and circularly polarized IR fields.

Epithelial-to-Mesenchymal Transition
EMT

description: © Katz et al. The conserved Musashi (Msi) family of RNA binding proteins are expressed in stem/progenitor and cancer cells, but generally absent from differentiated cells, consistent with a role in cell state regulation. We found that Msi genes are rarely mutated but frequently overexpressed in human cancers and are associated with an epithelial-luminal cell state. Using ribosome profiling and RNA-seq analysis, we found that Msi proteins regulate translation of genes implicated in epithelial cell biology and epithelial-to-mesenchymal transition (EMT), and promote an epithelial splicing pattern. Overexpression of Msi proteins inhibited the translation of Jagged1, a factor required for EMT, and repressed EMT in cell culture and in mammary gland in vivo. Knockdown of Msis in epithelial cancer cells promoted loss of epithelial identity. Our results show that mammalian Msi proteins contribute to an epithelial gene expression program in neural and mammary cell types.

description: © 2014 Kim et al. Objective: Enhancing structural and functional integrity of mitochondria is an emerging therapeutic option against endothelial dysfunction. In this study, we sought to investigate the effect of fluid shear stress on mitochondrial biogenesis and mitochondrial respiratory function in endothelial cells (ECs) using in vitro and in vivo complementary studies.Methods and Results: Human aortic- or umbilical vein-derived ECs were exposed to laminar shear stress (20 dyne/cm 2) for various durations using a cone-and-plate shear apparatus. We observed significant increases in the expression of key genes related to mitochondrial biogenesis and mitochondrial quality control as well as mtDNA content and mitochondrial mass under the shear stress conditions. Mitochondrial respiratory function was enhanced when cells were intermittently exposed to laminar shear stress for 72 hrs. Also, shear-exposed cells showed diminished glycolysis and decreased mitochondrial membrane potential (ΔΨm). Likewise, in in vivo experiments, mice that were subjected to a voluntary wheel running exercise for 5 weeks showed significantly higher mitochondrial content determined by en face staining in the conduit (greater and lesser curvature of the aortic arch and thoracic aorta) and muscle feed (femoral artery) arteries compared to the sedentary control mice. Interestingly, however, the mitochondrial biogenesis was not observed in the mesenteric artery. This region-specific adaptation is likely due to the differential blood flow redistribution during exercise in the different vessel beds.Conclusion: Taken together, our findings suggest that exercise enhances mitochondrial biogenesis in vascular endothelium through a shear stress-dependent mechanism. Our findings may suggest a novel mitochondrial pathway by which a chronic exercise may be beneficial for vascular function.

description: The dynamics of a harmonically trapped three-dimensional Yukawa ball of charged dust particles immersed in plasma is investigated as function of external magnetic field and Coulomb coupling parameter using molecular dynamics simulation. It is shown that the harmonically trapped dust particles organize themselves into nested spherical shells. The particles start rotating in a coherent order as the magnetic field reaches a critical value corresponding to the coupling parameter of the system of dust particles. The magnetically controlled charged dust cluster of finite size undergoes a first-order phase transition from disordered to ordered phase. At sufficiently high coupling and strong magnetic field, the vibrational mode of this finite-sized charged dust cluster freezes, and the system retains only rotational motion.

description: © 2014 American Chemical Society. The activity of the M2 proton channel of the influenza A virus is controlled by pH. The tautomeric state and conformation of His37, a key residue in the M2 transmembrane four-helix bundle, controls the gating of the channel. Previously, we compared the energetics and dynamics of two alternative conformations of the doubly protonated state at neutral pH, namely, a 4-fold symmetric "histidine-box" and a 2-fold symmetric "dimer-of-dimers", and proposed a multiconfiguration model for this charge state. Here, we elaborate this model by further studying configurations of the His37 tetrad in the triply protonated state and its subsequent deprotonation via quantum mechanics/molecular mechanics (QM/MM) molecular dynamics (MD) simulations, starting with the aforementioned configurations, to gain information about proton release in a viral membrane environment. Interestingly, the two configurations converge under acidic pH conditions. Protons can be transferred from one charged His37 to a neighboring water cluster at the C-terminal side of the channel when the Trp41 gate is open transiently. With limited backbone expansion, the free energy barrier for proton release to the viral interior at low pH is ∼6.5 kcal/mol in both models, which is much lower than at either neutral pH or for an isolated His37 cluster without a membrane environment. Our calculations also suggest that the M2 protein would seem to exclude the entrance of anions into the central channel through a special mechanism, due to the latter's potential inhibitory effect on proton conduction.

description: © 2014 Xu et al. The limited resource or strength model of self-control posits that the use of self-regulatory resources leads to depletion and poorer performance on subsequent self-control tasks. We conducted four studies (two with community samples, two with young adult samples) utilizing a frequently used depletion procedure (crossing out letters protocol) and the two most frequently used dependent measures of self-control (handgrip perseverance and modified Stroop). In each study, participants completed a baseline self-control measure, a depletion or control task (randomized), and then the same measure of self-control a second time. There was no evidence for significant depletion effects in any of these four studies. The null results obtained in four attempts to replicate using strong methodological approaches may indicate that depletion has more limited effects than implied by prior publications. We encourage further efforts to replicate depletion (particularly among community samples) with full disclosure of positive and negative results. Copyright:
Inference on copula-based correlation structures

description: We propose an extension of the approach provided by Kluppelberg and Kuhn (2009) for inference on second-order structure moments. As in Kluppelberg and Kuhn (2009) we adopt a copula-based approach instead of assuming normal distribution for the variables, thus relaxing the equality in distribution assumption. A new copula-based estimator for structure moments is investigated. The methodology provided by Kluppelberg and Kuhn (2009) is also extended considering the copulas associated with the family of Eyraud-Farlie-Gumbel-Morgenstern distribution functions (Kotz, Balakrishnan, and Johnson, 2000, Equation 44.73). Finally, a comprehensive simulation study and an application to real financial data are performed in order to compare the different approaches.

description: Total Defence is a defence policy combining and extending the concept of military defence and civil defence. While several countries have adopted total defence as their defence policy, very few studies have investigated its effectiveness. With the rapid proliferation of social media and digitalisation, many social studies have been focused on investigating policy effectiveness through specially curated surveys and questionnaires either through digital media or traditional forms. However, such references may not truly reflect the underlying sentiments about the target policies or initiatives of interest. People are more likely to express their sentiment using communication mediums such as starting topic thread on forums or sharing memes on social media. Using Singapore as a case reference, this study aims to address this research gap by proposing TotalDefMeme, a large-scale multi-modal and multi-attribute meme dataset that captures public sentiments toward Singapore's Total Defence policy. Besides supporting social informatics and public policy analysis of the Total Defence policy, TotalDefMeme can also support many downstream multi-modal machine learning tasks, such as aspect-based stance classification and multi-modal meme clustering. We perform baseline machine learning experiments on TotalDefMeme and evaluate its technical validity, and present possible future interdisciplinary research directions and application scenarios using the dataset as a baseline.

Rupture du silence. L'écriture engagée de Gisèle Pineau
Creators: name: Celot, Stephanie <1972>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2011
Subjects: L-LIN/03 Letteratura francese

description: A writer by passion and a psychiatric nurse by profession, Gisèle Pineau is described as the new feminine voice of the literature from the French Antilles (Martinique and Guadeloupe). In all her novels, she explores the human condition and more specifically that of women. Breaking the silence that oppresses Antillean women, Gisèle Pineau delves into the destinies of women from Guadeloupe, scrutinizing the environment of her island and elsewhere, reinventing the French language, and giving voice and identity to all those women who have never had the possibility to express themselves. 
After having introduced the author in a postcolonial context linked with the theory of the feminine writing and its expressions in Caribbean literature, the plight of women is described through the experience of their bodies in Antillean society and elsewhere. The author focuses on physical and psychological violence denouncing the treatment of women. Escaping from oppression, women look for the space to rebuild a new life and a new identity.
Phylogeny and population dynamics in European Reticulitermes and Kalotermes genera (Insecta, Isoptera)

description: The aim of this thesis is to detect the phylogeny and the population dynamics of the European termites of the genera Reticulitermes and Kalotermes, by the use of different mitochondrial (16S, COI/tRNA/COII, CR) and nuclear (microsatellites and Inter-SINE) molecular markers.
In the phylogenetic analyses, the obtained results have well defined the cladogenetic events that generated the nowadays species biodiversity of the genus Reticulitermes, while the analysis of the Kalotermes flavicollis taxon showed the presence of at least four genetic clades, defined on the basis of the geographical distance. 
The second part of the thesis is centred on the population dynamics of two species: Reticulitermes urbis and Kalotermes flavicollis. The first species, native of the Balkans, is known to be present in some cities of Italy and France. I’ve analyzed the colony genetic structure of the introduced population of Bagnacavallo (RA, Italy), using nine microsatellite loci. The obtained results are in accordance with those obtained from another population in France: this species in fact confirms its invasive and infestation capacities. The analysis of the natural population of K. flavicollis, performed with a combination of mitochondrial (control region) and nuclear (microsatellites and I-SINE) markers, clearly evidenced the presence of two genetic lineages that coexist in the same area. Moreover, results clearly indicate that the cross-breeding is allowed.
Finally, the whole results are discussed in a comparative view to better understand the differences in ecology, evolutionary dynamics and colony social structure between these two genera.

description: © 2014 Brickman et al. Background: Non-suicidal self-injury (NSSI) is a major concern in both clinical and non-clinical populations. It has been approximated that 65-80% of individuals with borderline personality disorder (BPD) engage in some form of NSSI. Despite such high co-morbidity, much still remains unknown about the relationship between NSSI and BPD symptomatology. The goal of the current study was to identify individual BPD symptoms and higher order BPD factors that increase one's vulnerability of NSSI engagement among a college sample. It was hypothesized that the BPD factor of emotion dysregulation and the BPD symptoms of affect instability and intense anger/aggression would be associated with the presence and frequency of NSSI. Method: Seven hundred twenty four undergraduates (61.2% female) completed self-report measures of BPD symptomology and NSSI history. Results: Regression analyses revealed that among the individual BPD symptoms, past suicidality, impulsivity, chronic emptiness, and identity disturbance were each significantly, positively associated with lifetime history of NSSI, whereas unstable relationships were negatively associated with lifetime history of NSSI. The BPD symptom associated with NSSI frequency was dissociation. Among the BPD factors, emotion dysregulation and disturbed relatedness were both associated with NSSI history, but only disturbed relatedness was associated with NSSI frequency. Conclusion: Findings show partial support for the importance of emotion dysregulation in the relationship between NSSI and BPD symptomatology, but also suggest that the relationship may be more complex and not solely based on emotion dysregulation.

description: The dynamics of a degree of freedom associated to an axial vector in contact with a heat bath is decribed by means of a probability distribution function obeying a Fokker-Planck equation. The equation is derived by using mesoscopic non-equilibrium thermodynamics and permits a formulation of a dynamical theory for the axial degree of freedom (orientation, polarization) and its associated order parameter. The theory is used to describe dielectric relaxation in homogeneous and non-homogeneous systems in the presence of strong electric fields. In the homogeneous case, we obtain the dependence of the relaxation time on the external field as observed in experiments. In the non-homogeneous case, our model account for the two observed maxima of the dielectric loss giving a good quantitative description of experimental data at all frequencies, especially for systems with low molecular mass.

description: Amyloid peptides nucleate from monomers to aggregate into fibrils through primary nucleation. Pre-existing fibrils can then act as seeds for additional monomers to fibrillize through secondary nucleation. Both nucleation processes occur simultaneously, yielding a distribution of fibril polymorphs that can generate a spectrum of neurodegenerative effects. Understanding the mechanisms driving polymorph structural distribution during both nucleation processes is important for uncovering fibril structure-function relationships, as well as for creating polymorph distributions in vitro that better match fibril structures found in vivo. Here, we explore how cross-seeding wild-type (WT) Aβ1-40 with Aβ1-40 mutants E22G (Arctic) and E22Δ (Osaka), as well as with WT Aβ1-42, affects the distribution of fibril structural polymorphs and how changes in structural distribution impact toxicity. Transmission electron microscopy analysis revealed that fibril seeds derived from mutants of Aβ1-40 imparted their structure to WT Aβ1-40 monomers during secondary nucleation, but WT Aβ1-40 fibril seeds do not affect the structure of fibrils assembled from mutant Aβ1-40 monomers, despite the kinetic data indicating accelerated aggregation when cross-seeding of any combination of mutants. Additionally, WT Aβ1-40 fibrils seeded with mutant fibrils produced similar structural distributions to the mutant seeds with similar cytotoxicity profiles. This indicates that mutant fibril seeds not only impart their structure to growing WT Aβ1-40 aggregates but also impart cytotoxic properties. Our findings establish a relationship between the fibril structure and the phenotype on a polymorph population level and that these properties can be passed on through secondary nucleation to the succeeding generations of fibrils.
