description: We construct merger trees for galaxies identified in a cosmological hydrodynamic simulation and use them to characterize predicted merger rates as a function of redshift, galaxy mass, and merger mass ratio. At z = 0.3, we find a mean rate of 0.054 mergers per galaxy per Gyr above a 1 : 2 mass ratio threshold for massive galaxies (baryonic mass above 6.4 × 1010 M), but only 0.018 Gyr-1 for lower mass galaxies. The mass ratio distribution is R for the massive galaxy sample, so high-mass mergers dominate the total merger growth rate. The predicted rates increase rapidly with increasing redshift, and they agree reasonably well with observational estimates. A substantial fraction of galaxies do not experience any resolved mergers during the course of the simulation, and even for the high-mass sample, only 50% of galaxies experience a greater than 1 : 4 merger since z = 1. Typical galaxies thus have fairly quiescent merger histories. We assign bulge-to-disk ratios to simulated galaxies by assuming that mergers above a mass ratio threshold Rmajor convert stellar disks into spheroids. With Rmajor values of 1 : 4, we obtain a fairly good match to the observed dependence of the early-type fraction on galaxy mass. However, the predicted fraction of truly bulge-dominated systems (fbulge > 0.8) is small, and producing a substantial population of bulge-dominated galaxies may require a mechanism that shuts off gas accretion at late times and/or additional processes (besides major mergers) for producing bulges.
Unravelling the function of ataxin-3 as a deubiquitinating enzyme: is this function altered in Machado-Joseph disease?

description: Machado-Joseph disease (MJD) is a genetic form of neurodegeneration that is typically diagnosed around the fourth decade of life and results in progressive loss of movement, balance and coordination. Despite the single cause of MJD being established almost three decades ago, it remains a fatal disease with no effective treatments. In MJD, mutation of the ATXN3 gene results in polyglutamine expansion of the ataxin-3 protein, enhancing its propensity to misfold, aggregate, and form the neuronal intranuclear inclusions which are characteristic of MJD. Ataxin-3 is known to function as a deubiquitinating enzyme within the ubiquitin-proteasome system, and an increasing body of evidence suggests that its deubiquitinating function is altered by polyglutamine expansion in MJD. Whether polyglutamine expansion results in a gain or loss of ataxin-3's deubiquitinating function, as well as the downstream consequences of this on targets of ataxin-3, is yet to be completely unravelled.This thesis identified that wild-type and polyglutamine expanded human ataxin-3 alter the abundance of K63- and K48-ubiquitinated proteins. A list of proteins with differential co-interaction with K48-linked ubiquitin due to the expression of polyglutamine-expanded human ataxin-3 was subsequently generated by LFQ proteomics, and three proteins of interest – matrin-3 (matr3), polyadenylate-binding protein 1 (PABPC1), and ELAV-like protein 1 (ELAVL1) – were subsequently explored. This thesis identified that matr3 is K48-ubiquitinated, has an altered abundance in ATXN3-expressing N2A cells and in a MJD mouse model, and co-localises with ataxin-3. However, polyglutamine expansion of ataxin-3 does not impact the subcellular localisation of matr3, the abundance of matr3 co-interacting with K48-linked ubiquitin, or the degree of co-localisation between matr3 and ataxin-3. The abundance of PABPC1 and ELAVL1, as well as the abundance of PABPC1 co-interacting with K48-linked ubiquitin chains were also found to be unaltered by polyglutamine expansion in human ataxin-3. Overall, this thesis contributes to our understanding of how polyglutamine expansion in ataxin-3 impacts its function as a deubiquitinating enzyme, and the consequences of this on the abundance, subcellular localisation, and ubiquitination of downstream proteins, with the hope of identifying novel treatment avenues for MJD.

description: The dissipative dynamics of Gaussian squeezed states (GSS) and coherent superposition states (CSS) are analytically obtained and compared. Time scales for sustaining different quantum properties such as squeezing, negativity of the Wigner function or photon number distribution are calculated. Some of these characteristic times also depend on initial conditions. For example, in the particular case of squeezing, we find that while the squeezing of CSS is only visible for small enough values of the field intensity, in GSS it is independent of this quantity, which may be experimentally advantageous. The asymptotic dynamics however is quite similar as revealed by the time evolution of the fidelity between states of the two classes.

Large isosymmetric reorientation of oxygen octahedra rotation axes in epitaxially strained perovskites

description: Using first-principles density functional theory calculations, we discover an anomalously large bi-axial strain-induced octahedral rotation axis reorientation in orthorhombic perovskites with tendency towards rhombohedral symmetry. The transition between crystallographically equivalent (isosymmetric) structures with different octahedral rotation magnitudes originates from strong strain--octahedral rotation coupling available to perovskites and the energetic hierarchy among competing octahedral tilt patterns. By elucidating these criteria, we suggest many functional perovskites would exhibit the transition in thin film form, thus offering a new landscape in which to tailor highly anisotropic electronic responses.

La nascita delle Scuole Normali doveva rispondere ad uno dei più importanti limiti per lo sviluppo del sistema scolastico del Paese, e cioè lo scarsissimo numero di maestri allora disponibili, specialmente nel Mezzogiorno. Nel ripercorrere lastoria della Real Scuola Normale di Catania, dall’Unità alla Riforma Gentile, il presente articolo recupera alla memoria rare ed inedite testimonianze che raccontano la storia di alcune tra le sue prime allieve-maestre.

The pro-dictatorial decree of Antonio Mordini, of 17 October 1860, established the adoption of the Piedmontese scholastic systems in Sicily. The Sicilian region equipped itself with Normal Schools for master pupils and teacher pupils, founded in Palermo, Catania and Messina. The Normal Schools responded to one of the most important limitations for the development of the country's school system, namely the very limited number of teachers available at the time, especially in the South. In retracing the history of the Real Scuola Normale of Catania, from the Unification to the Gentile Reform, this article brings to mind rare and unpublished testimonies that tell the story of some of its first student teachers.

Crater mound formation by wind erosion on Mars

description: Most of Mars' ancient sedimentary rocks by volume are in wind-eroded sedimentary mounds, but the connections between mound form and wind erosion are unclear. We perform mesoscale simulations of different crater and mound morphologies to understand the formation of sedimentary mounds. As crater depth increases, slope winds produce increased erosion near the base of the crater wall, forming mounds. Peak erosion rates occur when the crater depth is ~2 km. Mound evolution depends on the size of the host crater. In smaller craters mounds preferentially erode at the top, becoming more squat, while in larger craters mounds become steeper-sided. This agrees with observations where smaller craters tend to have proportionally shorter mounds, and larger craters have mounds encircled by moats. If a large-scale sedimentary layer blankets a crater, then as the layer recedes across the crater it will erode more towards the edges of the crater, resulting in a crescent-shaped moat. When a 160 km diameter mound-hosting crater is subject to a prevailing wind, the surface wind stress is stronger on the leeward side than on the windward side. This results in the center of the mound appearing to `march upwind' over time, and forming a `bat-wing' shape, as is observed for Mt. Sharp in Gale crater.

description: We extended the classic anorthoscopic viewing procedure to test a model of visualization of 3D structures from 2D cross-sections. Four experiments were conducted to examine key processes described in the model, localizing cross-sections within a common frame of reference and spatiotemporal integration of cross sections into a hierarchical object representation. Participants used a hand-held device to reveal a hidden object as a sequence of cross-sectional images. The process of localization was manipulated by contrasting two displays, in situ vs. ex situ, which differed in whether cross sections were presented at their source locations or displaced to a remote screen. The process of integration was manipulated by varying the structural complexity of target objects and their components. Experiments 1 and 2 demonstrated visualization of 2D and 3D line-segment objects and verified predictions about display and complexity effects. In Experiments 3 and 4, the visualized forms were familiar letters and numbers. Errors and orientation effects showed that displacing cross-sectional images to a remote display (ex situ viewing) impeded the ability to determine spatial relationships among pattern components, a failure of integration at the object level.
Simulating elliptic flow with viscous hydrodynamics

description: In this work we simulate a viscous hydrodynamical model of non-central Au-Au collisions in 2+1 dimensions, assuming longitudinal boost invariance. The model fluid equations were proposed by Öttinger and Grmela \cite{OG}. Freezeout is signaled when the viscous corrections become large relative to the ideal terms. Then viscous corrections to the transverse momentum and differential elliptic flow spectra are calculated. When viscous corrections to the thermal distribution function are not included, the effects of viscosity on elliptic flow are modest. However, when these corrections are included, the elliptic flow is strongly modified at large $p_T$. We also investigate the stability of the viscous results by comparing the non-ideal components of the stress tensor ($π^{ij}$) and their influence on the $v_2$ spectrum to the expectation of the Navier-Stokes equations ($π^{ij} = -η\llangle \partial_i u_j \rrangle$). We argue that when the stress tensor deviates from the Navier-Stokes form the dissipative corrections to spectra are too large for a hydrodynamic description to be reliable. For typical RHIC initial conditions this happens for $η/s \gsim 0.3$.

description: The continuum discretized coupled channels (CDCC) method is compared to the exact solution of the three-body Faddeev equations in momentum space. We present results for: i) elastic and breakup observables of d-12C at E_d=56 MeV, ii) elastic scattering of d-58Ni at E_d=80 MeV, and iii) elastic, breakup and transfer observables for 11Be+p at E_{11Be}/A=38.4 MeV. Our comparative studies show that, in the first two cases, the CDCC method is a good approximation to the full three-body Faddeev solution, but for the 11Be exotic nucleus, depending on the observable or the kinematic regime, it may miss out some of the dynamic three-body effects that appear through the explicit coupling to the transfer channel.

description: We predict a large anomalous Nernst effect in the inverse Heusler compensated ferrimagnets Ti$_2$Mn$X$ ($X$=Al,Ga,In) with vanishing net magnetic moments. Though the net magnetic moment is zero, the Weyl points in these systems lead to a large anomalous Nernst conductivity (ANC) due to the lack of a magnetic sublattice that inverses the sign of the Berry curvature. In comparison to the noncollinear antiferromagnets Mn$_3$Sn and Mn$_3$Ge, the high ANC stems almost entirely from the Weyl points in this class of compounds, and thus, it is topologically protected. This work shows for the first time a large ANC with zero net magnetic moments in collinear systems, which is helpful for comprehensive understanding of the thermoelectric effect in zero-moment magnetic materials and its further applications.

description: We report measurements of the temperature and pressure dependence of the electrical resistivity of single crystalline iron-based chalcogenide Cs0.8Fe2Se2. In this material superconductivity Tc~30K develops from a normal state with extremely large resistivity. At ambient pressure a large "hump" in the resistivity is observed around 200K. Under pressure, the resistivity decreases by two orders of magnitude, concomitant with a sudden Tc suppression around p~8GPa. Even at 9GPa a metallic resistivity state is not recovered, and the ρ(T) "hump" is still detected. A comparison of the data measured upon increasing and decreasing the external pressure leads us to suggest that superconductivity is not related to this hump.

description: We study thermalization of a two-component Bose-Hubbard model by exact diagonalization. Initially the two components do not interact and are each at equilibrium but with different temperatures. As the on-site inter-component interaction is turned on, perfect thermalization occurs. Remarkably, not merely those simple "realistic" physical observables thermalize but even the density matrix of the \textit{whole} system---the time-averaged density matrix of the system can be well approximated by that of a canonical ensemble. A conjecture about this fact is put forward.

Η ρομποτική αποτελεί ένα κομβικό κομμάτι στην εκπαίδευση των νέων μηχανικών που θα χρησιμοποιήσουν σχετικά συστήματα στην παραγωγική διαδικασία. Οι ρομποτικοί βραχίονες αποτελούν ένα από τα βασικά πεδία της ρομποτικής που μελετώνται στα σχετικά εκπαιδευτικά προγράμματα.
Στη παρούσα διπλωματική εργασία σχεδιάστηκε ένας ρομποτικός βραχίονας με χρήση λογισμικού παραμετρικής σχεδίασης λαμβάνοντας υπόψιν διάφορους κατασκευαστικούς περιορισμούς καθώς και τη δυνατότητα να μπορεί να κατασκευαστεί εύκολα με χρήση τρισδιάστατου εκτυπωτή.
Στη συνέχεια το μοντέλο του βραχίονα εισήχθη στο λογισμικό Matlab, δημιουργήθηκε ένα απλοποιημένο μοντέλο σε VRML και αναπτύχθηκαν κατάλληλες συναρτήσεις για τον έλεγχο του βραχίονα από το χρήστη. Στόχος της παρούσας εργασίας είναι να παρέχει ένα εύχρηστο εργαλείο που θα επιτρέψει στους χρήστες να κατανοήσουν τις βασικές έννοιες που σχετίζονται με τους ρομποτικές βραχίονες και τη κινηματική τους.

description: Robotics are a key component of the Industry 4.0 and therefore there is an increased demand on related skills and dexterities. Robotics are in the core of the related educational aspects and robotic manipulators are of great importance.
In the current work, we have designed a robotic manipulator using a parametric modeling software, considering different constraint including but not limited to the potential motors and electronics that might be used for developing the real manipulator, the potential development using 3d printing techniques.
The detailed CAD model was imported in Matlab and a simplified VRML model was
developed. A simplified interface that allows the movement to the simulated environment was also developed. We also provide simple routines that allow kinematic analysis of the manipulator.
The scope of this work was to provide a tool that will allow the users to understand the basic principles of the robotic manipulator’s movement and perform simple kinematic analysis.

description: We study the gravitational-wave peak luminosity and radiated energy of quasicircular neutron star mergers using a large sample of numerical relativity simulations with different binary parameters and input physics. The peak luminosity for all the binaries can be described in terms of the mass ratio and of the leading-order post-Newtonian tidal parameter solely. The mergers resulting in a prompt collapse to black hole have largest peak luminosities. However, the largest amount of energy per unit mass is radiated by mergers that produce a hypermassive neutron star or a massive neutron star remnant. We quantify the gravitational-wave luminosity of binary neutron star merger events, and set upper limits on the radiated energy and the remnant angular momentum from these events. We find that there is an empirical universal relation connecting the total gravitational radiation and the angular momentum of the remnant. Our results constrain the final spin of the remnant black-hole and also indicate that stable neutron star remnant forms with super-Keplerian angular momentum.

description: The purpose of this study was to examine how discrete segments of contiguous space arising from perceptual or cognitive channels are mentally concatenated. We induced and measured errors in each channel separately, then summed the psychophysical functions to accurately predict pointing to a depth specified by both together. In Experiment 1, subjects drew a line to match the visible indentation of a probe into a compressible surface. Systematic perceptual errors were induced by manipulating surface stiffness. Subjects in Experiment 2 placed the probe against a rigid surface and viewed the depth of a hidden target below it from a remote image with a metric scale. This cognitively mediated depth judgment produces systematic under-estimation (Wu et al. in IEEE Trans Vis Comput Grap 11(6):684-693, 2005; confirmed here). In Experiment 3, subjects pointed to a target location detected by the indented probe and displayed remotely, requiring mental concatenation of the depth components. The model derived from the data indicated the errors in the components were passed through the integration process without additional systematic error. Experiment 4 further demonstrated that this error-free concatenation was intrinsically spatial, rather than numerical.

description: There is a popular hypothesis that performance on implicit and explicit memory tasks reflects 2 distinct memory systems. Explicit memory is said to store those experiences that can be consciously recollected, and implicit memory is said to store experiences and affect subsequent behavior but to be unavailable to conscious awareness. Although this division based on awareness is a useful taxonomy for memory tasks, the authors review the evidence that the unconscious character of implicit memory does not necessitate that it be treated as a separate system of human memory. They also argue that some implicit and explicit memory tasks share the same memory representations and that the important distinction is whether the task (implicit or explicit) requires the formation of a new association. The authors review and critique dissociations from the behavioral, amnesia, and neuroimaging literatures that have been advanced in support of separate explicit and implicit memory systems by highlighting contradictory evidence and by illustrating how the data can be accounted for using a simple computational memory model that assumes the same memory representation for those disparate tasks.

description: We consider the simple changepoint problem setting, where observations are independent, iid pre-change and iid post-change, with known pre- and post-change distributions. The Shiryaev-Roberts detection procedure is known to be asymptotically minimax in the sense of minimizing maximal expected detection delay subject to a bound on the average run length to false alarm, as the latter goes to infinity. Here we present other optimality properties of the Shiryaev-Roberts procedure.

description: In the world of upper limb prostheses, few companies dominate the majority of the market. They propose different kinds of hand, wrist and elbow prostheses but their control is often difficult to understand by the patients. We have decided to develop new myoelectric prosthetic arm (elbow, wrist and hand) by axing our development on the use of new technologies and facility of use for the patient. In this paper, we are explaining in details the different kinds of prostheses currently proposed to the amputees, their advantages and their drawbacks, the descriptions of the patients' needs and the possible improvements of the product. We will develop the designing choices of our prosthesis and the movements it can realize. Then we will explain the simplified control of the product by the patient and its first reactions. Finally, we will conclude by the news ideas and the next researches to concretize.

description: The $k$-Colouring problem is to decide if the vertices of a graph can be coloured with at most $k$ colours for a fixed integer $k$ such that no two adjacent vertices are coloured alike. If each vertex u must be assigned a colour from a prescribed list $L(u) \subseteq \{1,\cdots, k\}$, then we obtain the List $k$-Colouring problem. A graph $G$ is $H$-free if $G$ does not contain $H$ as an induced subgraph. We continue an extensive study into the complexity of these two problems for $H$-free graphs. The graph $P_r+P_s$ is the disjoint union of the $r$-vertex path $P_r$ and the $s$-vertex path $P_s$. We prove that List $3$-Colouring is polynomial-time solvable for $(P_2+P_5)$-free graphs and for $(P_3+P_4)$-free graphs. Combining our results with known results yields complete complexity classifications of $3$-Colouring and List $3$-Colouring on $H$-free graphs for all graphs $H$ up to seven vertices.

description: The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has recently released its 12.5 year data set. I will summarize the GW results and their implications for limits on Supermassive Black Hole Binaries through hierarchical galaxy merging. These limits are starting to substantially constrain models for SMBHB. We anticipate detection of the stochastic background of GWs from these sources within the next 3 - 7 years.
