description: Several proposed models for dark matter posit the existence of self-interaction processes that can impact the shape of dark matter halos, making them more spherical than the ellipsoidal halos of collisionless dark matter. One method of probing the halo shapes, and thus the strength of the dark matter self-interaction, is by measuring the shape of the X-ray gas that traces the gravitational potential in relaxed elliptical galaxies. In this work we identify a sample of 11 relaxed, isolated elliptical galaxies and measure the ellipticity of the gravitating matter using X-ray images from the XMM-Newton and Chandra telescopes. We explore a variety of different mass configurations and find that the dark matter halos of these galaxies have ellipticities around $ε\approx 0.2-0.5$. While we find non-negligible scatter in the ellipticity distribution, our results are consistent with some degree of self-interaction at the scale of $σ/m \sim 1$ cm$^2$/g, yet they also remain compatible with a cold dark matter scenario. We additionally demonstrate how our results can be used to directly constrain specific dark matter models and discuss implications for current and future simulations of self-interacting dark matter models.

Squashing Models for Optical Measurements in Quantum Communication

description: Measurements with photodetectors necessarily need to be described in the infinite dimensional Fock space of one or several modes. For some measurements a model has been postulated which describes the full mode measurement as a composition of a mapping (squashing) of the signal into a small dimensional Hilbert space followed by a specified target measurement. We present a formalism to investigate whether a given measurement pair of mode and target measurements can be connected by a squashing model. We show that the measurements used in the BB84 protocol do allow a squashing description, although the six-state protocol does not. As a result, security proofs for the BB84 protocol can be based on the assumption that the eavesdropper forwards at most one photon, while the same does not hold for the six-state protocol.

An impulse to the ground to end rolling with slipping

Year: 2021
Subjects: subject: Physics Education (physics.ed-ph)
subject: FOS: Physical sciences

description: Several scenarios used in teaching feature a rolling motion with slipping that transitions to one without through friction with the ground. We summarise these transitions by introducing an unknown impulse that is transferred to the ground. Accounting for this in the conservation of angular and linear momentum, we can deduce the final state of these scenarios in a compact manner and without requiring details of the friction. Contrasting this technique with an explicit calculation of the friction illustrates how collisions and conservation laws allow to solve problems involving complex interactions by summarising them. We exemplify our technique with three scenarios: a moving ball starting to roll, a turning wheel being released on the ground, and a monowheel breaking.

description: We perform the first global QCD analysis of pion valence, sea quark, and gluon distributions within a Bayesian Monte Carlo framework with threshold resummation on Drell-Yan cross sections at next-to-leading log accuracy. Exploring various treatments of resummation, we find that the large-$x$ asymptotics of the valence quark distribution $\sim (1-x)^{β_v}$ can differ significantly, with $β_v$ ranging from $\approx 1$ to $> 2.5$ at the input scale. Regardless of the specific implementation, however, the resummation induced redistribution of the momentum between valence quarks and gluons boosts the total momentum carried by gluons to $\approx 40\%$, increasing the gluon contribution to the pion mass to $\approx 40$ MeV.

description: Quasinormal modes of perturbed black holes have recently gained much interest because of their tight relations with the gravitational wave signals emitted during the post-merger phase of a binary black hole coalescence. One of the intriguing features of these modes is that they respect the no-hair theorem, and hence, they can be used to test black hole space-times and the underlying gravitational theory. In this paper, we exhibit three different aspects of how black hole quasinormal modes could be altered in theories beyond Einstein general relativity. These aspects are the direct alterations of quasinormal modes spectra as compared with those in general relativity, the violation of the geometric correspondence between the high-frequency quasinormal modes and the photon geodesics around the black hole, and the breaking of the isospectrality between the axial and polar gravitational perturbations. Several examples will be provided in each individual case. The prospects and possible challenges associated with future observations will be also discussed.

description: We report influence of encapsulated C60 molecules on electron transport in carbon-nanotube peapod quantum dots. We find atomic-like behaviors with doubly degenerate electronic levels, which exist only around ground states, by single electron spectroscopy measured at low back-gate voltages (Vbg). Correlation with presence of nearly free electrons (NFEs) unique to the peapods is discussed. Moreover, we find anomalously high values of power a observed in power laws in conductance versus energy relationships, which are strongly associated with the doubly degenerate levels. It is revealed that the powers originate from Tomonaga-Luttinger liquid via the occupied doubly degenerate levels. Our observations clarify that the encapsulated C60 molecules form doubly degenerate levels only at ground state in peapod quantum dots and do not eliminate a ballistic charge transport.

description: We introduce a simple general method for finding the equilibrium distribution for a class of widely used inexact Markov Chain Monte Carlo algorithms. The explicit error due to the non-commutivity of the updating operators when numerically integrating Hamilton's equations can be derived using the Baker-Campbell-Hausdorff formula. This error is manifest in the conservation of a ``shadow'' Hamiltonian that lies close to the desired Hamiltonian. The fixed point distribution of inexact Hybrid algorithms may then be derived taking into account that the fixed point of the momentum heatbath and that of the molecular dynamics do not coincide exactly. We perform this derivation for various inexact algorithms used for lattice QCD calculations.

Exploring the mechanisms involved in prion degradation and spreading from cell-to-cell in neuronal cell models
Creators: name: Marzo, Ludovica

Year: 2011

description: Transmissible spongiform encephalopathies (TSE), also known as prion diseases, are fatal neurodegenerative disorders present both in human and animals with different aetiology as they can occur genetically, spontaneously or by infection (Prusiner 1998). TSE are caused by the presence of proteinacious aggregates, called ‘prions’, in brains of afflicted individuals. According to the ‘protein-only’ hypothesis, the central event of prion pathogenesis is the conformational change of the cellular protein, PrPC, into its pathological counterpart, PrPSc in a process in which PrPSc acts as a template (Prusiner 1998). Differently from PrPC, mainly constitutes of α-helices, PrPSc is enriched in β-sheets, aggregation-prone and resistant to treatment with proteinase K. Despite the intense research, many questions in prion biology are still open related to both the physiological functions of PrPC and mechanism of the disease caused by the misfolded form PrPSc. Thus, exploring some of these aspects at the molecular and cellular level is of fundamental importance for a better understanding of these fatal disorders and for developing potential therapeutical approaches. However, due to the lack of PrPSc-specific antibodies, PrPSc cellular trafficking, production and degradation are poorly defined.
In the first part of my thesis I investigated the role of autophagy in prion disease. I demonstrated that although autophagic pathway is stimulated by prion infection, it is not involved in prion degradation. Furthermore, I showed that tamoxifen and its metabolite 4-hydroxil-tamoxifen (OHT) (previously shown to be autophagy inducers) reduce scrapie burden by redistributing cholesterol and PrP to lysosomes in an autophagy-independent manner. These data confirm the role of the lysosomal pathway in prion degradation and of cholesterol in prion formation. Furthermore, since tamoxifen is a wide-available pharmaceutical tool it might have potential application in therapy for prion disease.
Another important question in prion biology is related to the spreading of PrPSc. At the different stages of its lethal journey to the central nervous system, PrPSc is transferred from one cell to another and this passage can involve several mechanisms. Recently our laboratory has shown that PrPSc hijacks intercellular membranous channels, called tunneling nanotubes (TNT), for intercellular spread (Gousset et al., 2009; Langevin et al 2009). Therefore, in the second part of my PhD work I have better characterized TNT-mediated trafficking of PrPSc between neuronal cells, as model of prion infection. I also identified factors that could be involved in TNT formation and in the resulting transfer of PrPSc between cells. These results will contribute to the characterization of both TNT formation and prion spreading and open the way to further investigations.

La persuasione dolce. La tradizione del gioachimismo nella cronachistica francescana tra XIII e XIV secolo.
Creators: name: Nardone, Marina
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2011

description: Il presente lavoro si prefigge di rintracciare le ricadute materiali nell’ambivalente gesto storico di registrare e interpretare il reale. La tradizione del gioachimismo viene così rinvenuta principalmente attraverso la cronachistica, per focalizzare l’attenzione sull’intelligere storico ed in particolar modo attraverso la storiografia francescana, quale luogo privilegiato della consapevolezza e di una vera e propria assunzione di responsabilità per la salvezza del mondo cristiano. Il lavoro è diviso in tre parti: nella prima, dedicata al XII secolo, si cerca di definire il campo di interesse relativo al pensiero dell’Abate calabrese; trattando, innanzitutto, il rapporto tra il tema della conversione e quello dell’apocalittica, al fine di mostrare come il suo filoebraismo fosse in realtà un’esigenza teoretica. Si tenta inoltre di mantenere uniti due concetti apparentemente antitetici, ovvero quello della novità della sua filosofia e quello del suo perfetto inserimento nel filone culturale del XII secolo.
La seconda e la terza parte della tesi trattano rispettivamente del XIII e del XIV secolo, secondo un andamento speculare: esse partono, in entrambi i casi, da una breve introduzione storico-filosofica, proseguendo in una marcata e approfondita analisi di un’unica fonte privilegiata, quale portavoce essenziale dei temi principali. Segue un’analisi comparativa, volta a confermare o a problematizzare i risultati emersi e lo studio di alcuni fenomeni, che dialogano senza soluzione di continuità attraverso il tempo.Attraverso quest’analisi si identifica principalmente un filo diretto tra la profezia, la predicazione e la persecuzione come espressione della teorizzazione, della pratica e della ricezione del concetto di fine.
Seismic migration by Chebychev transform : a novel approach
Creators: name: Mitsakis, Dimitrios Michael
Publisher: name: University of British Columbia
Year: 2010

description: Chebychev semi-discretizations for both ordinary and partial differential equations are explored. The Helmholtz, heat, Schrӧdinger and 15° migration equations are investigated. The Galerkin, pseudospectral and tau projection operators are employed, while the Crank-Nicolson scheme is used for the integration of the time (depth) dependence. The performance of the Chebychev scheme is contrasted with the performance of the finite difference scheme for Dirichlet and Neumann boundary conditions. Comparisons between all finite difference, Fourier and Chebychev migration algorithms are drawn as well. Chebychev expansions suffer from neither the artificial dispersion dispersion of finite difference approximations nor the demand for a periodic boundary structure of Fourier expansions. Thus, it is shown that finite difference schemes require at least one order of magnitude more points in order to match the accuracy level of the Chebychev schemes. In addition, the Chebychev migration algorithm is shown to be free of the wraparound problem, inherent in migration procedures based on Fourier transform.

description: We examine the impact of a complex absorbing potential on electron transport, both in the continuum and on a lattice. This requires the use of non-Hermitian Hamiltonians; the required formalism is briefly outlined. The lattice formulation allows us to study the interesting problem of an electron interacting with a stationary spin, and the subsequent time evolution of the electron and spin properties as the electron is absorbed after the initial interaction. Remarkably, the properties of the localized spin are affected 'at-a-distance' by the interaction of the (now entangled) electron with a complex potential.

description: Carbon nanotubes (CNTs) have attracted increasing attention because of their unique structural, mechanical, and electronic properties. Surface chemistry modifications are also useful and critical to manipulate the adsorptive properties of CNTs and develop their potential of environmental application. Therefore, the main objectives of this study were to investigate the optimal synthesis methods or characteristics identification of multiwall CNTs (MWCNTs) and the environmental application of lead ions adsorptive removal by CNTs. Experimentally, the MWCNTs of well-graphited walls were obtained with reductive potassium metals of catalytic hexachlorobenzene-thermal routes in the presence of Co/Ni catalyst precursors at 503-623 K for 8- 12 hr. The diameters of MWCNTs ranged of 30-100 nm by TEM microphotos. In addition, fine structures or surface chemical modification of MWCNTs or Co/Ni precursors were further identified by EDS, XRPD, X-ray absorption near edge structural (XANES) or extended Xray absorption fine structural (EXAFS) spectroscopy. 1.

description: Die Fähigkeit von Unternehmen möglichst genau und schnell auf Kundenwünsche zu reagieren ist angesichts des globalen Wettbewerbs und sich verkürzender Produktlebenszyklen ein zentraler Erfolgsfaktor in vielen Branchen. Produktentwickler stehen dadurch vor der Herausforderung die Unsicherheit hinsichtlich der marktlichen Anforderungen an ein Produkt bereits frühzeitig zu reduzieren. Als zentraler wissensgenerierender Aktivität im Produktentwicklungsprozess kommt dabei der Produktvalidierung eine besondere Bedeutung zu. Gerade Validierungsaktivitäten in der Frühen Phase des Produktentwicklungsprozesses sind jedoch mit besonderen Herausforderungen verbunden. Der Einsatz der Virtual-Reality- und Augmented-Reality-Technologie zur Validierung interaktiver Produkte in frühen Entwicklungsphasen bietet das Potenzial diesen Herausforderungen zu begegnen. Die Technologien ermöglichen es mithilfe illusorischer Stimuli unterschiedliche Varianten eines Produkts frühzeitig für den Anwender erfahrbar zu machen. Im Vergleich zur Virtual-Reality-Technologie besteht das besondere Potenzial für den Einsatz der Augmented-Reality-Technologie bei der Validierung interaktiver Produkte in der Möglichkeit zur bedarfsgerechten Kombination physischer und virtueller Prototypen. Aufbauend auf den Inhalten der KaSPro – Karlsruher Schule für Produktentwicklung als modelltheoretischem und methodischem Rahmen wird in dieser Arbeit eine Systematik zur methodischen Unterstützung der Validierung interaktiver Produkte in Augmented-Reality-Umgebungen in frühen Entwicklungsphasen entwickelt und in drei Fallstudien angewandt und evaluiert. Zu den zwei zentralen Bestandteilen der Systematik zählen ein Beschreibungsmodell für AR-basierte Validierungsumgebungen sowie ein Referenzprozessmodell. Das Referenzprozessmodell unterstützt Produktentwickler und Produktentwicklungsteams entlang des gesamten Vorgehens zur AR-gestützten, kundenintegrierten Produktvalidierung in der Frühen Phase. Es umfasst das Festlegen und Konkretisieren der Validierungsziele, das Konfigurieren und den Aufbau der AR-basierten Validierungsumgebung, die Durchführung des Tests und die abschließende Interpretation der Testergebnisse. Die Evaluationsergebnisse aus den durchgeführten Fallstudien bestätigen die grundsätzliche Eignung der Systematik für die praktische Anwendung und zeigen ihren Beitrag zur Reduktion von Unsicherheiten bzgl. Kunden- und Anwenderanforderungen in frühen Entwicklungsphasen.

description: Using SDSS I data, we have analysed the stellar distribution of the Leo II dwarf spheroidal galaxy (distance of 233 kpc) to search for evidence of tidal deformation. The existing SDSS photometric catalogue contains gaps in regions of high stellar crowding, hence we filled the area at the centre of Leo II using the DAOPHOT algorithm applied to the SDSS images. The combined DAOPHOT-SDSS dataset contains three-filter photometry over a 4x4 square degree region centred on Leo II. By defining a mask in three-filter colour-magnitude space, we removed the majority of foreground field stars. We have measured the following Leo II structural parameters: a core radius of r_c = 2.64 +/- 0.19 arcmin (178 +/- 13 pc), a tidal radius of r_t = 9.33 +/- 0.47 arcmin (632 +/- 32 pc) and a total V-band luminosity of L_V = (7.4 +/- 2.0) times 10^5 L_sun (M_V = -9.9 +/- 0.3). Our comprehensive analysis of the Leo II structure did not reveal any significant signs of tidal distortion. The internal structure of this object contains only mild isophotal twisting. A small overdensity was discovered appoximately 4.5 tidal radii from the Leo II centre, however we conclude it is unlikely to be material tidally stripped from Leo II based on its stellar population, and is most likely a foreground overdensity of stars. Our results indicate that the influence of the Galactic graviational field on the structure of Leo II has been relatively mild. We rederived the mass-to-light ratio of this system using existing kinematic data combined with our improved structural measurements, and favour the scenario in which Leo II is strongly dominated by dark matter with (M/L)_V ~ 100 in solar units.

description: We study the neutralino relic density in the minimal supersymmetric standard model with natural light Higgs sector in which all Higgs masses, the supersymmetry (SUSY) breaking parameters, and the higgsino mass parameter mu are of order the weak scale. To realize this situation we adopt nonuniversal Higgs masses at the grand unified scale. We show that in some parameter space in which the SUSY breaking parameters are comparatively small, not only the constraint from the observed relic density of dark matter but also the LEP Higgs bound and the constraint from the b ->s gamma process are satisfied. In most of the parameter space, the neutralino relic density becomes smaller than the observed relic density in contrast with the results in the constrained minimal SUSY standard model (CMSSM). The reason is that the neutralino coannihilation processes to Higgs bosons open even if the gaugino mass is small and the cross sections become large due to the small dimensionful parameters. Especially small mu parameter and the light CP-odd Higgs, which are difficult to be realized in the CMSSM, are essential for the result.

description: We compare experimental resistivity data on Ga_{1-x}Mn_xAs films with theoretical calculations using a scaling theory for strongly disordered ferromagnets. All characteristic features of the temperature dependence of the resistivity can be quantitatively understood through this approach as originating from the close vicinity of the metal-insulator transition. In particular, we find that the magnetic field induced changes in resistance cannot be explained within a mean-field treatment of the magnetic state, and that accounting for thermal fluctuations is crucial for a quantitative analysis. Similarly, while the non-interacting scaling theory is in reasonable agreement with the data, we find clear evidence in favor of interaction effects at low temperatures.

A rich variety of evolving patterns is revealed where players movement has a decisive role on the evolutionary outcome. For example, intensive individual mobility may jeopardize the survival of the population, but if we increase players movement further then it can save the population. Notably, the collective drive of population members is capable to compensate the negative consequence of intensive movement and keeps the system alive. When the drive becomes biased then the resulting unidirectional flow alters the stable pattern and produce a stripe-like state instead of the previously observed hexagonal arrangement of clusters. Interestingly, the rotation of stripes can be flipped if the individual movement exceeds a threshold value.

description: We present the observations of the reflection nebulae IC4954 and IC4955 region with the Infrared Camera (IRC) and the Far-Infrared Surveyor (FIS) on board the infrared astronomical satellite AKARI during its performance verification phase. We obtained 7 band images from 7 to 160um with higher spatial resolution and higher sensitivities than previous observations. The mid-infrared color of the S9W (9um) and L18W (18um) bands shows a systematic variation around the exciting sources. The spatial variation in the mid-infrared color suggests that the star-formation in IC4954/4955 is progressing from south-west to north-east. The FIS data also clearly resolve two nebulae for the first time in the far-infrared. The FIS 4-band data from 65um to 160um allow us to correctly estimate the total infrared luminosity from the region, which is about one sixth of the energy emitted from the existing stellar sources. Five candidates for young stellar objects have been detected as point sources for the first time in the 11um image. They are located in the red S9W to L18W color regions, suggesting that current star-formation has been triggered by previous star-formation activities. A wide area map of the size of about 1 x 1 (deg^2) around the IC4954/4955 region was created from the AKARI mid-infrared all-sky survey data. Together with the HI 21cm data, it suggests a large hollow structure of a degree scale, on whose edge the IC4954/4955 region has been created, indicating star formation over three generations in largely different spatial scales.

description: This paper evaluates the unethical actions of GSK, a pharmaceutical company headquartered in London, and the consequences of those actions. The company’s deceitful behavior was exposed by four former employees who filed suit against it. In its case with the U.S. Justice Department in 2012, it was found that GSK was guilty of falsely branding its drug products and keeping important health data from the FDA. Consequently, GSK paid $3 billion dollars to the U.S. Department of Justice and entered in a Corporate Integrity Agreement with the U.S. Government. The paper begins with an overview of who the whistleblowers are and follows with details regarding the specific wrongdoings that GSK engaged in, which made the whistleblowers come forward. GSK’s actions will be evaluated under PhRMA’s Guiding Principles on Direct to Consumer Advertisements about Prescription Medicines.
Searching for common hereditable genetic variants associated with risk of neuroblastoma development and progression.

description: Several neuroblastoma (NBL) susceptibility loci located in diverse genes (LINC00340, BARD1, LMO1, DUSP12, HSD17B12, DDX4, IL31RA, HACE1 and LIN28B) have been identified by genome-wide association studies (GWAS). The replication of association studies are mandatory to validate and comprehensively evaluate the impact of the identified NBL variants on disease risk and phenotype. To this purpose, during my PhD program I have genotyped in an Italian population 14 single nucleotide polymorphisms (SNPs), that have already been associated with NBL in European Americans. All NBL susceptibility genes replicated in the Italian dataset except for two of them, and the most significant SNP was rs6435862 in BARD1. Interestingly, BARD1 showed an additional and independent SNP association (rs7585356). This variant also influenced BARD1 mRNA expression in LCLs and NBL cell lines. Moreover, a cumulative effect of risk variants on NBL risk and development of high-risk phenotype was observed in a dose-dependent manner. These results provide further evidence that the risk loci identified in GWAS contribute to NBL susceptibility in distinct populations and strengthen the role of BARD1 as major genetic contributor to NBL risk.
   Recent studies have demonstrated a role for interleukin(IL)-6, a pro-inflammatory cytokine, in progression and development of diverse cancers. Moreover, it has been demonstrated that the SNP rs1800795 in IL-6 promoter is associated with inferior clinical outcomes in patients with high-risk NBL. In particular, the major allele is reported as associated with lower survival. Thus, it has been analyzed an Italian population to validate these data. The results showed that the SNP was not implicated in susceptibility to NBL development while the minor allele is significantly associated with a reduction of the overall survival, advanced stage, and high-risk phenotype. Moreover, the analysis of expression indicate the minor allele as correlated with increased level of IL-6 expression. Kaplan-Meier analysis demonstrated that high levels of IL-6 were associated with poor outcome. These findings indicate that the biological effect of this SNP in relation to promotion of cancer progression is consistent with the observed decreased survival time.

description: We present an analysis of a Suzaku observation of the link region between the galaxy clusters A399 and A401. We obtained the metallicity of the intracluster medium (ICM) up to the cluster virial radii for the first time. We determine the metallicity where the virial radii of the two clusters cross each other (~2 Mpc away from their centers) and found that it is comparable to that in their inner regions (~0.2 Zsun). It is unlikely that the uniformity of metallicity up to the virial radii is due to mixing caused by a cluster collision. Since the ram-pressure is too small to strip the interstellar medium of galaxies around the virial radius of a cluster, the fairly high metallicity that we found there indicates that the metals in the ICM are not transported from member galaxies by ram-pressure stripping. Instead, the uniformity suggests that the proto-cluster region was extensively polluted with metals by extremely powerful outflows (superwinds) from galaxies before the clusters formed. We also searched for the oxygen emission from the warm--hot intergalactic medium in that region and obtained a strict upper limit of the hydrogen density (nH<4.1x10^-5 cm^-3).

title: Behavioural and neural correlates of emergent proto-languages and joint action

description: Haptic communication between humans plays a vital role in society. Although this form of communication is ubiquitous at all levels of society and human development, little is known about how synchronized coordination of motion between two persons would lead to higher-order cognitive functions used in haptic communication. During this project, a novel experimental paradigm was developed. In it, participants used their hands to control the rod to collect the coins on the screen. The aim was to investigate the neural and behavioural correlates of emergent haptic communication between paired participants. During the experiment, haptic interactions and neural synchronizations between paired participants were recorded and compared to baseline pairs. Baseline pairs were created from non-interacting single participants. During the Ph.D., two experiments were conducted. The first focused on haptic interactions and characterising the emergent proto-language that participants used to communicate. The second experiment used a novel hyperscanning methodology to isolate the synchronization characteristics of emergent proto-languages and social interactions. The EEG experiment presented here explores the interbrain synchronization between interacting participants systematically. This paradigm allows participants to interact with each other freely. This genuinely novel paradigm allows researchers to study pairs of participants in truly social situations. By comparing pairs with single participants, it has been possible to identify behavioural and neural characteristics related to the emergent proto-language that participants are using as a means of communication. Both of the experiments detailed here describe pioneering work in the study of social interactions and the emergence of protolanguages.

description: PHILIPPINES Villarta, an oncology nurse who volunteers at the Cancer Warriors Foundation, shared her reflections on the COVID-19 situation. She notes, “Personal messages, group chats, and calls are valuable venues not only for greetings but also for assessments of their physical and psycho-emotional condition. Often, to check-in with families, we simply exchange text messages (SMS) or viber/messenger messages to let them know we are thinking and praying for them and to inquire on their condition and challenges/needs. As needed, we then connect them to healthcare workers and for those experiencing moderate to extreme distress, we link them up with psychologists/social workers providing online services.”
