description: We examine how amplitude noise in queries to the oracle degrades a performance of quantum search algorithm. The Grover search and similar techniques are widely used in various quantum algorithms, including cases where rival parties are fighting over confidential data. Hence, the oracle-box wires become the subject of competing activity with an alteration of their normal functioning. Of course, many kinds of errors could arise in this way. Possible influence of dephasing on quantum search was already addressed in the literature. Amplitude damping is another type of errors that should be analyzed first. To study the problem, we introduce a simple model of collective distortions with the use of amplitude damping channel. All the quantities of interest should be considered as functions of the number of Grover's iterations. In particular, we investigate the success probability with respect to the parameter that characterizes the level of amplitude errors. The success probability degrades significantly even if the error amount is not essential. Namely, this probability soon enough reduces to a value close to one half. We also study trade-off relations between quantum coherence and the success probability in the presence of amplitude noise.

description: It is well known that in two spatial dimensions the fractional quantum Hall effect (FQHE) deals with point-like anyons that carry fractional electric charge and statistics. Moreover, in presence of a SO(3) order parameter, point-like skyrmions emerge and play a central role in the corresponding quantum Hall ferromagnetic phase. In this work, we show that in six spatial dimensions, the FQHE for extended objects shares very similar features with its two-dimensional counterpart. In the higher-dimensional case, the electromagnetic and hydrodynamical one-form gauge fields are replaced by three-form gauge fields and the usual point-like anyons are replaced by membranes, namely two-dimensional extended objects that can carry fractional charge and statistics. We focus on skyrmionic membranes, which are associated to a SO(5) order parameter and give rise to an higher-dimensional generalizaton of the quantum Hall ferromagnetism. We show that skyrmionic membranes naturally couple to the curved background through a generalized Wen-Zee term and can give us some insights about the chiral conformal field theory on the boundary. We then present a generalization of the Witten effect in six spatial dimensions by showing that one-dimensional extended monopoles (magnetic strings) in the bulk of the FQH states can acquire electric charge through an axion field by becoming dyonic strings.

description: Η οξεία εκκολπωματίτιδα είναι επιπλοκή της εκκολπωμάτωσης, με συχνότερη εντόπιση το παχύ έντερο και επηρεάζει κυρίως το δυτικό κόσμο. Τα αίτιά της είναι πολυπαραγοντικά με κύρια διατροφικά, αλλαγές στο μικροβίωμα, γενετικούς και περιβαλλοντικούς παράγοντες.

Με βάση την κλινική εξέταση και αρωγό τις εργαστηριακές εξετάσεις αλλά και τις απεικονιστικές μεθόδους με εκλογής την αξονική τομογραφία τριπλής αντίθεσης, θέτουμε τη διάγνωση και κατατάσσουμε την οξεία εκκολπωματίτιδα κατά WSES και Hinchey. Οι ταξινομήσεις αυτές καθορίζουν την θεραπευτική μας προσέγγιση. Αυτή μπορεί να συνίσταται από απλή παρακολούθηση και πιθανή λήψη αντιβιοτικών σε εξωτερική βάση, ως νοσηλεία και ενδοφλέβια χορήγηση αντιβιοτικών ή και σε παρεμβατικές μεθόδους (διαδερμικές ή ανοικτές και λαπαροσκοπικές χειρουργικές επεμβάσεις).

description: Acute diverticulitis is a complication of diverticulosis, mostly located in the colon and affecting mainly the western world. Its causes are multifactorial including nutritional habits, changes in the microbiome, genetic and other environmental factors. The clinical manifestations vary from mild local and systemic symptoms to severe and intense. Based on the clinical examination combined with laboratory tests, as well as the imaging studies with the gold standard being triple contrast computed tomography, we establish the diagnosis and classify the acute diverticulitis according to WSES and Hinchey classifications. These classifications determine the therapeutic approach. This can consist either of simple monitoring and probable oral antibiotic intake on an outpatient basis, or hospitalization and intravenous antibiotics, or even of interventional methods (percutaneous or open or laparoscopic surgery). Ιncreased vigilance is needed for the control of possible complications (intestinal obstruction, rupture, abscess, fistula, peritonitis) and their treatment. Of therapeutic importance are: the immediate patient support, selection of the patient group to receive antibiotic coverage, and further intervention (percutaneous or surgical) as needed, based on the WSES (2020) and Hinchey (2005) classifications.

description: Computing superconducting properties starting from an exactly solvable model for a doped Mott insulator stands as a grand challenge. We have recently shown that this can be done starting from the Hatsugai-Kohmoto (HK) model which can be understood generally as the minimal model that breaks the non-local $\mathbb Z_2$ symmetry of a Fermi liquid, thereby constituting a new quartic fixed point for Mott physics [Phillips et al., Nature Physics 16, 1175 (2020); Huang et al., Nature Physics (2022)]. In the current work, we compute the thermodynamics, condensation energy, and electronic properties such as the NMR relaxation rate $1/T_1$ and ultrasonic attenuation rate. Key differences arise with the standard BCS analysis from a Fermi liquid: 1) the free energy exhibits a local minimum at $T_p$ where the pairing gap turns on discontinuously above a critical value of the repulsive HK interaction, thereby indicating a first-order transition, 2) a tri-critical point emerges, thereby demarcating the boundary between the standard second-order superconducting transition and the novel first-order regime, 3) Mottness changes the sign of the quartic coefficient in the Landau-Ginzburg free-energy fuctional relative to that in BCS, 4) as this obtains in the strongly interacting regime, it is Mott physics that underlies the generic first-order transition, 5) the condensation energy exceeds that in BCS theory suggesting that multiple Mott bands might be a way of enhancing superconducting, 6) the heat-capacity jump is non-universal and increases with the Mott scale, 7) Mottness destroys the Hebel-Slichter peak in NMR, and 8) Mottness enhances the fall-off of the ultrasonic attenuation at the pairing temperature $T_p$. As several of these properties are observed in the cuprates, our analysis here points a way forward in computing superconducting properties of strongly correlated electron matter.

description: We study a strongly interacting, fermionic fluid in the presence of an applied magnetic field using a holographic framework. At low temperatures, translation symmetry is spontaneously broken and the resulting phase is a striped Hall fluid. Due to the magnetic field, an electric field applied parallel to the stripes causes the stripes to slide, a phenomenon we coin "Hall sliding." We also investigate the magneto-transport of the system in the presence of an explicit translation symmetry-breaking lattice which pins the stripes. Electrical properties are well represented by a hydrodynamical model, which gives us further insight into particle-like cyclotron and pseudo-Goldstone excitations we observe. The DC conductivities obey a novel semi-circle law, which we derive analytically in the translationally invariant ground state at low temperature.

description: We investigate the formation of topological defects in the course of a dynamical phase transition with different boundary conditions in a ring from AdS/CFT correspondence. According to the Kibble-Zurek mechanism, quenching the system across the critical point to symmetry-breaking phase will result in topological defects -- winding numbers -- in a compact ring. By setting two different boundary conditions, i.e., Dirichlet and Neumann boundary conditions for the spatial component of the gauge fields in the AdS boundary, we achieve the holographic superfluid and holographic superconductor models, respectively. In the final equilibrium state, different configurations of the order parameter phases for these two models indicate a persistent superflow in the holographic superfluid, however, the holographic superconductor lacks this superflow due to the existence of local gauge fields. The two-point correlation functions of the order parameter also behave differently. In particular, for holographic superfluid the correlation function is a cosine function depending on the winding number. The correlation function for the holographic superconductor, however, decays rapidly at short distances and vanishes at long distance, due to the random localities of the gauge fields. These results are consistent with our theoretical analysis.

description: We consider a class of Hamiltonian systems in 3 degrees of freedom, with a particular type of quadratic integral and which includes the rational Calogero-Moser system as a particular case. For the general class, we introduce separation coordinates to find the general separable (and therefore Liouville integrable) system, with two quadratic integrals. This gives a coupling of the Calogero-Moser system with a large class of potentials, generalising the series of potentials which are separable in parabolic coordinates. Particular cases are {\em superintegrable}, including Kepler and a resonant oscillator. The initial calculations of the paper are concerned with the flat (Cartesian type) kinetic energy, but in Section \ref{sec:conflat-general}, we introduce a {\em conformal factor} $φ$ to $H$ and extend the two quadratic integrals to this case. All the previous results are generalised to this case. We then introduce some 2 and 3 dimensional symmetry algebras of the Kinetic energy (Killing vectors), which restrict the conformal factor. This enables us to reduce our systems from 3 to 2 degrees of freedom, giving rise to many interesting systems, including both Kepler type and Hénon-Heiles type potentials on a Darboux-Koenigs $D_2$ background.

description: Geometry-based point cloud compression (G-PCC) can achieve remarkable compression efficiency for point clouds. However, it still leads to serious attribute compression artifacts, especially under low bitrate scenarios. In this paper, we propose a Multi-Scale Graph Attention Network (MS-GAT) to remove the artifacts of point cloud attributes compressed by G-PCC. We first construct a graph based on point cloud geometry coordinates and then use the Chebyshev graph convolutions to extract features of point cloud attributes. Considering that one point may be correlated with points both near and far away from it, we propose a multi-scale scheme to capture the short- and long-range correlations between the current point and its neighboring and distant points. To address the problem that various points may have different degrees of artifacts caused by adaptive quantization, we introduce the quantization step per point as an extra input to the proposed network. We also incorporate a weighted graph attentional layer into the network to pay special attention to the points with more attribute artifacts. To the best of our knowledge, this is the first attribute artifacts removal method for G-PCC. We validate the effectiveness of our method over various point clouds. Objective comparison results show that our proposed method achieves an average of 9.74% BD-rate reduction compared with Predlift and 10.13% BD-rate reduction compared with RAHT. Subjective comparison results present that visual artifacts such as color shifting, blurring, and quantization noise are reduced.

description: The velocity-space distribution of the solar neighbourhood stars shows complex substructures. Most of the previous studies use static potentials to investigate their origins. Instead we use a self-consistent $N$-body model of the Milky Way, whose potential is asymmetric and evolves with time. In this paper, we quantitatively evaluate the similarities of the velocity-space distributions in the $N$-body model and that of the solar neighbourhood, using Kullback-Leibler divergence (KLD). The KLD analysis shows the time evolution and spatial variation of the velocity-space distribution. The KLD fluctuates with time, which indicates the velocity-space distribution at a fixed position is not always similar to that of the solar neighbourhood. Some positions show velocity-space distributions with small KLDs (high similarities) more frequently than others. One of them locates at $(R,ϕ)=(8.2\;\mathrm{kpc}, 30^{\circ})$, where $R$ and $ϕ$ are the distance from the galactic centre and the angle with respect to the bar's major axis, respectively. The detection frequency is higher in the inter-arm regions than in the arm regions. In the velocity maps with small KLDs, we identify the velocity-space substructures, which consist of particles trapped in bar resonances. The bar resonances have significant impact on the stellar velocity-space distribution even though the galactic potential is not static.

description: Disordered packings of unbonded, semiflexible fibers represent a class of materials spanning contexts and scales. From twig-based bird nests to unwoven textiles, bulk mechanics of disparate systems emerge from the bending of constituent slender elements about impermanent contacts. In experimental and computational packings of wooden sticks, we identify prominent features of their response to cyclic oedometric compression: non-linear stiffness, transient plasticity, and eventually repeatable velocity-independent hysteresis. We trace these features to their micromechanic origins, identified in characteristic appearance, disappearance, and displacement of internal contacts.

description: The Laser Interferometer Space Antenna (LISA) is a future space-based gravitational wave (GW) detector designed to be sensitive to sources radiating in the low frequency regime (0.1 mHz to 1 Hz). LISA's interferometer signals will be dominated by laser frequency noise which has to be suppressed by about 7 orders of magnitude using an algorithm called Time-Delay Interferometry (TDI). Arm locking has been proposed to reduce the laser frequency noise by a few orders of magnitude to reduce the potential risks associated with TDI. In this paper, we present an updated performance model for arm locking for the new LISA mission using 2.5 Gm arm lengths, the currently assumed clock noise, spacecraft motion, and shot noise. We also update the Doppler frequency pulling estimates during lock acquisition.

description: Das Phänomen des demografischen Wandels bringt gesellschaftliche Veränderungen mit sich. Unter anderem werden Menschen mit einer geistigen Behinderung älter und ihre Lebenserwartung gleicht sich den Menschen ohne geistige Behinderung an. Durch diesen Wandel gewinnt das Bedürfnis nach Inklusion von geistig behinderten Menschen im Alter zunehmend an Bedeutung. Aufgrund der Tatsache, dass Menschen mit einer geistigen Behinderung während ihres ganzen Lebens Nachteilen ausgesetzt sind, werden diese Benachteiligungen im Alter aus finanzieller, sozialer und biologischer Sicht noch verstärkt. Die vorliegende Literaturarbeit zeigt auf, was Inklusion von Menschen mit einer geistigen Behinderung im Alter bedeutet und welche Einflussfaktoren hinsichtlich ihrer Inklusionschancen im Alter bestehen. In diesem Zusammenhang werden wechselseitig beeinflussende Erklärungsbezüge mit den sozialversicherungsrechtlichen Rahmenbedingungen, der finanziellen Armut und mit dem Individuum selbst auf der bio-psycho-sozialen Ebene gemacht. Das Ziel der Arbeit ist es aufzuzeigen, wie Menschen mit einer geistigen Behinderung im Alter von Professionellen der Sozialarbeit bestmöglich beim Übertritt ins Pensionsalter unterstützt werden können, damit die Betroffenen eine höhere Chancengleichheit gegenüber der restlichen Gesellschaft erfahren und das Maximum an Selbstbestimmung erlangen. Die systemische Beratung dient als Ausgangslage. Des Weiteren wird näher auf die fünf Säulen der Identität und die interne und externe Ressourcenerschliessung eingegangen.

Communication-Efficient Active Reconstruction using Self-Organizing Gaussian Mixture Models

Publisher: name: Carnegie Mellon University
Year: 2025
Subjects: classificationCode: 4007
subject: Control engineering, mechatronics and robotics

description: For the multi-robot active reconstruction task, this thesis proposes using Gaussian mixture models (GMMs) as the map representation that enables multiple downstream tasks: high-fidelity static scene reconstruction, communication-efficient map sharing, and safe informative planning. A new method called Self-Organizing Gaussian mixture modeling (SOGMM) is proposed that estimates the model complexity (i.e., number of Gaussian components) based on the depth and intensity data observed by the robots. This method provides higher fidelity maps and lower map sizes compared to prior GMM-based and grid-based methods. Due to the lower map sizes, sharing the maps amongst robots or to a base station is tractable on low-bandwidth communication channels. To enable safe informative planning, a motion primitives based planner is developed with two robot-robot and robot-environment collision avoidance approaches. Both approaches provide collision avoidance capability without maintaining a global occupancy grid, which can often consume too much memory onboard the robots. Informative planning is enabled via an information-theoretic action selection strategy with the robots sharing plans and map fragments over a serial connection. The final active reconstruction system is demonstrated in a real cave with two quadcopters equipped with RGB-D cameras. The overall approach provides up to two orders of magnitude reduction in communication bandwidth usage while providing higher depth and intensity reconstruction accuracy compared to dense grid-based methods.

L’economia politica di Roberto Michels negli anni torinesi

description: This paper reconstructs the lectureship in political economy awarded by the University of Turin in 1909 to Robert Michels who, some years after, became world-wide famous due to his La sociologia del partito politico nella democrazia moderna. The decision to award this lectureship was made by Achille Loria, who had a rather generous conception of the scope of political economy, against the advice of Luigi Einaudi who, notwhistanding his personal friendship with Michels, disliked the Michelsian mix between political economy and sociology. During his Torinese period, Michels published critical studies on cooperation as an alternative principle for economic organization and economic theory; the history of marxism; the history of political economy in Italy; and Italian colonialism. Last but not least, in his Sociologia there are also some hints on the economics of political phenomenon.

description: We investigate the leading order correction of anomalous magnetic moment (AMM) to the electron in weak magnetic field and find that the magnetic correction is negative and magnetic field dependent, indicating a magnetic catalysis effect for the electron gas. In the laboratory to measure the $g-2$, the magnitude of the magnetic field $B$ is several $\mathrm{T}$, correspondingly the magnetic correction to the AMM of electron/muon is around $10^{-34}$/$10^{-42}$, therefore the magnetic correction can be safely neglected in current measurement. However, when the magnitude of the magnetic field strength is comparable with the electron mass, the magnetic correction of electron's AMM will become considerable. This general magnetic correction to charged fermion's AMM can be extended to study QCD matter under strong magnetic field.

description: Understanding the role of regularization is a central question in Statistical Inference. Empirically, well-chosen regularization schemes often dramatically improve the quality of the inferred models by avoiding overfitting of the training data. We consider here the particular case of L 2 and L 1 regularizations in the Maximum A Posteriori (MAP) inference of generative pairwise graphical models. Based on analytical calculations on Gaussian multivariate distributions and numerical experiments on Gaussian and Potts models we study the likelihoods of the training, test, and 'generated data' (with the inferred models) sets as functions of the regularization strengths. We show in particular that, at its maximum, the test likelihood and the 'generated' likelihood, which quantifies the quality of the generated samples, have remarkably close values. The optimal value for the regularization strength is found to be approximately equal to the inverse sum of the squared couplings incoming on sites on the underlying network of interactions. Our results seem largely independent of the structure of the true underlying interactions that generated the data, of the regularization scheme considered, and are valid when small fluctuations of the posterior distribution around the MAP estimator are taken into account. Connections with empirical works on protein models learned from homologous sequences are discussed.
Dalla qualità alla quantità. L’eugenica nel pensiero di Roberto Michels

description: Though the connection between eugenics and the Left has been largely investigated, this topic has been insofar quite neglected with regard to the Italian case. This paper is focused on Robert Michels’ contributions in the field of eugenics, from 1906 to 1924.
The case of Michels’ eugenics, shifting from the initial position in favour of birth control, feminism and socialism to the 1910s-1920s pronatalist and “quantitative” eugenic orientation, provides fascinating insights on the complex cultural and political origins of Italian “Latin” eugenics.

description: There are currently many large-field surveys operational and planned including the powerful Vera C. Rubin Observatory Legacy Survey of Space and Time. These surveys will increase the number and diversity of transients dramatically. However, for some transients, like supernovae (SNe), we can gain more understanding by directed observations (e.g. shock breakout, $γ$-ray detections) than by simply increasing the sample size. For example, the initial emission from these transients can be a powerful probe of these explosions. Upcoming ground-based detectors are not ideally suited to observe the initial emission (shock emergence) of these transients. These observations require a large field-of-view X-ray mission with a UV follow up within the first hour of shock breakout. The emission in the first one hour to even one day provides strong constraints on the stellar radius and asymmetries in the outer layers of stars, the properties of the circumstellar medium (e.g. inhomogeneities in the wind for core-collapse SNe, accreting companion in thermonuclear SNe), and the transition region between these two. This paper describes a simulation for the number of SNe that could be seen by a large field of view lobster eye X-ray and UV observatory.

Three-dimensional simulations of the jet feedback mechanism in common envelope jets supernova

description: We conduct three-dimensional hydrodynamical simulations of common envelope jets supernova (CEJSN) events where we assume that a neutron star (NS) launches jets as it orbits inside the outer zones of a red supergiant (RSG) envelope, and find the negative jet feedback coefficient to be ~0.1-0.2. This coefficient is the factor by which the jets reduce the mass accretion rate onto the NS as they remove mass from the envelope and inflate bubbles (cocoons). Our results suggest that in most CEJSN events the NS-RSG binary system experiences the grazing envelope evolution (GEE) before it enters a full common envelope evolution (CEE). We also find that the jets induce upward and downward flows in the RSG envelope. These flows together with the strong convection of RSG stars might imply that energy transport by convection in CEJSNe is very important. Because of limited numerical resources we do not include in the simulations the gravity of the NS, nor the accretion process, nor the jets launching process, and nor the gravity of the deformed envelope. Future numerical simulations of CEE with a NS/BH companion should include the accretion process onto the NS (and vary the jets' power accordingly), the full gravitational interaction of the NS with the RSG, and energy transport by the strong convection.

Riforma o rivoluzione sociale? Il problema della collocazione politica di R. Michels all’interno del movimento socialista
Creators: name: Volpe, Giorgio

description: Michels’ political position within the international socialist movement is still a controversial issue. In the literature there are two interpretive trends: the older places Michels’ political thought in the revolutionary trade-unionist thinking; the second considers it as a product of the orthodox socialism. This paper intends to provide a critic interpretation which includes both the linear level of the theoretic analysis and the historical reconstruction. The research, therefore, studies the moments and the places of Michels’ political militancy by the analysis of his political articles and studies about the history of the labor movement and the political sociology. The essay considers also the reports of the Italian and German socialist party’s congress, together with Michels’ correspondence and some interesting autobiographical notes.

description: In preparation for the High Luminosity LHC, the entire tracker detector of the CMS experiment will be exchanged as part of the Phase-2 Upgrade. The new Outer Tracker will comprise approximately 13,000 silicon sensor modules, of which 7608 are "2S modules" consisting of two parallel mounted silicon strip sensors, and 5592 are "PS modules" consisting of one pixel and one strip sensor in a single module. These modules provide tracking information to the Level 1 trigger by correlating the hit information of both sensor layers, allowing discrimination of particle tracks by their transverse momentum. To guarantee successful operation during data-taking, the production of the outer tracker modules has to fulfill strict requirements. This note will discuss the assembly procedures as well as some key results of the electronic, thermal and vibration tests performed at CERN for qualifying the 2S module design and for preparing the module assembly procedures.
Analysis of the Bax-Bak interaction during SAC-induced apoptosis

Publisher: name: University of Leicester

description: Taxol binds to β-tubulin preventing mitotic spindle formation and microtubule attachment to kinetochores. The presences of non-attached kinetochores activates the spindle assembly checkpoint (SAC) resulting in chronic activation of CDK1, mitotic arrest and apoptosis. Taxol- induced apoptosis occurs via the mitochondrial apoptosis pathway. The activation of the key regulators of apoptosis, Bak and Bax, results in the mitochondrial outer membrane permeabilization (MOMP) followed by the release of apoptotic factors such as cytochrome c. Recent studies from our lab demonstrated that Taxol- induced apoptosis is Bak and Bax dependent. However, the mechanism by which Bax accumulates at the mitochondrial outer membrane and whether Bak plays a role in this mechanism during SAC activation remain unknown.Therefore, I examined how Bak mediates the recruitment of the pro-apoptotic Bax into the mitochondrial outer membrane. I confirmed that Bak is required for Bax recruitment to mitochondria and subsequent cell death. By isolating the mitochondria from Taxol-arrested cells and Bak immunoprecipitation, I have demonstrated that Bak forms a complex with Bax and MPTP proteins VDAC2 and ANT2 which suggest the contribution of the pro apoptotic proteins in the pore formation during SAC- induced apoptosis. Also, a mitochondrial Bak IP mass spectrometry screen identified a 41 novel Bak interacting proteins. Finally, I examined the interaction between recombinant Bak and Bax to identify the key amino acid residues involved in the binding of the two proteins. My data confirmed the direct interaction between Bak and Bax at the canonical binding site (BH3: hydrophobic groove). My results also identified a novel amino acid responsible of Bak:Bax interaction as Bak Y89. A mutant Bak (Y89F) completely abolished the interaction between both proteins. In conclusion, this study confirmed the important role of pro-apoptotic Bak in recruiting Bax to the mitochondria of SAC activated cells. As Bak and Bax interaction is crucial in Taxol-induced apoptosis, the key amino acid residue that regulates Bak and Bax interaction has been identified.
