description: We introduce the concept of boundaries of a complex network as the set of nodes at distance larger than the mean distance from a given node in the network. We study the statistical properties of the boundaries nodes of complex networks. We find that for both Erdös-Rényi and scale-free model networks, as well as for several real networks, the boundaries have fractal properties. In particular, the number of boundaries nodes {\it B} follows a power-law probability density function which scales as $B^{-2}$. The clusters formed by the boundary nodes are fractals with a fractal dimension $d_{f} \approx 2$. We present analytical and numerical evidence supporting these results for a broad class of networks. Our findings imply potential applications for epidemic spreading.

description: We presented results on azimuthal correlation of net-charge with high $p_T$ trigger particles. It is found that the net-charge correlation shape is similar to that of total-charge. On the near-side, the net-charge and total-charge $p_T$ spectra have similar shape and both are harder than the inclusives. On the away-side, the correlated spectra are not much harder than the inclusives, and the net-charge/total-charge ratio increases with $p_T$ and is similar to the inclusive ratio.

description: Magnetic beads attract each other forming chains. We pushed such chains into an inclined Hele-Shaw cell and discovered that they spontaneously form self-similar patterns. Depending on the angle of inclination of the cell, two completely different situations emerge, namely, above the static friction angle the patterns resemble the stacking of a rope and below they look similar to a fortress from above. Moreover, locally the first pattern forms a square lattice, while the second pattern exhibits triangular symmetry. For both patterns, the size distributions of enclosed areas follow power laws. We characterize the morphological transition between the two patterns experimentally and numerically and explain the change in polarization as a competition between friction-induced buckling and gravity.

description: The structure and quantum state of the reactants have a profound impact on the kinetics and dynamics of chemical reactions. Over the past years, significant advances have been made in the control and manipulation of molecules with external electric and magnetic fields in molecular-beam experiments for investigations of their state-, structure- and energy-specific chemical reactivity. Whereas studies for neutrals have so far mainly focused on weak-field-seeking species, we report here progress towards investigating reactions of strong-field-seeking molecules by introducing a novel crossed-molecular-beam experiment featuring an electrostatic deflector. The new setup enables the characterisation of state- and geometry-specific effects in reactions under single-collision conditions. As a proof of principle, we present results on the chemi-ionisation reaction of metastable neon atoms with rotationally state-selected carbonyl sulfide (OCS) molecules and show that the branching ratio between the Penning and dissociative ionisation pathways strongly depends on the initial rotational state of OCS.

description: Self-propelled particles, which convert energy into mechanical motion, exhibit inertia if they have a macroscopic size or move inside a gaseous medium, in contrast to micron-sized overdamped particles immersed in a viscous fluid. Here we study an extension of the active Ornstein-Uhlenbeck model, in which self-propulsion is described by colored noise, to access these inertial effects. We summarize and discuss analytical solutions of the particle's mean-squared displacement and velocity autocorrelation function for several settings ranging from a free particle to various external influences, like a linear or harmonic potential and coupling to another particle via a harmonic spring. Taking into account the particular role of the initial particle velocity in a nonstationary setup, we observe all dynamical exponents between zero and four. After the typical intertial time, determined by the particle's mass, the results inherently revert to the behavior of an overdamped particle with the exception of the harmonically confined systems, in which the overall displacement is enhanced by inertia. We further consider an underdamped model for an active particle with a time-dependent mass, which critically affects the displacement in the intermediate time-regime. Most strikingly, for a sufficiently large rate of mass accumulation, the particle's motion is completely governed by inertial effects as it remains superdiffusive for all times.

description: ABSTRACT                      

Background: Substance use, involving alcohol or drugs, impacts all age groups, particularly adolescence and young adults, affecting health, quality of life, and involvement in crime. Over 29 million people worldwide suffer from substance-related disorders, impairing healthcare professionals' skills and potentially compromising patient safety. Therefore, the current study aimed to assess the magnitude of substance use and associated factors among medical residents in Addis Ababa, Ethiopia, in 2023.

Methods: A cross-sectional study was conducted among medical residents studying at four hospitals in Addis Ababa, Ethiopia: Yekatit 12 Hospital Medical College, St. Paul’s Hospital Millennium Medical College, Tikur Anbessa Specialized Hospital, and Myong Sung Christian Medical Centre. The study included 419 participants, who were selected proportionally from the four hospitals using a stratified sampling method. Descriptive statistics were computed and are presented in tables, graphs, and charts. To identify associated factors, a binary logistic regression model was used; bivariate analysis identified significant variables at p-values ≤ 0.25, while backward stepwise analysis identified independent associated factors at p-values ≤ 0.05.

0.25, while backward stepwise analysis identified independent associated factors at p-values ≤ 0.05.

Results: Two hundred eleven (50.4%, 95% CI=45.5%, 55.2%) resident doctors reported a history of substance use. Sex (AOR = 4.54; 95% CI (2.64, 7.80)), living arrangements of residents (living with friends (AOR = 3.92; 95% CI=1.84, 8.39) and living alone (AOR = 2.51; 95% CI=1.44, 4.36)), parental history of substance use (AOR = 2.45; 95% CI=1.29, 4.64), sibling history of substance use (AOR = 3.05; 95% CI=1.67, 5.57), and best friend’s history of substance use (AOR = 4.30; 95% CI=2.55, 7.25) were factors significantly associated with substance use history among resident doctors.

Conclusions: This study in Addis Ababa, Ethiopia, found that substance use among medical residents was significantly higher than reported in other studies. Factors including sex, department of residence, living arrangements, and family/peer history of substance use were significantly associated with substance use history. These findings underscore the vulnerability of medical residents to substance use and suggest a potential risk to their professional performance and patient safety. Implementing preventive strategies and support systems tailored to address these specific risk factors is crucial. Additionally, further research is warranted to explore the long-term implications of substance use on medical residents' well-being and their ability to provide quality healthcare in the Ethiopian context.

description: Collective rituals serve social functions for the groups that perform them, including identifying group members and signalling group commitment. A novel social group paradigm was used in an afterschool programme (N = 60 4–11-year-olds) to test the influence of participating in a ritual task on in-group displays and out-group monitoring over repeated exposures to the group. The results demonstrate that ritual participation increases in-group displays (i.e. time spent displaying materials to in-group members) and out-group monitoring (i.e. time spent looking at out-group members) compared with a control task across three time points. This study provides evidence for the processes by which rituals may influence children's behaviours towards in- and out-group members and discusses implications for understanding the development of ritual cognition and behaviour.

description: Accurate calibration of polarization dependent optical elements is often necessary in optical experiments. A versatile polarimeter device to measure the polarization state of light is a valuable tool in these experiments. Here we report a rotating waveplate-based polarimeter capable of complete Stokes vector analysis of collimated light. Calibration of the device allows accurate measurements over a range of wavelengths, with a bandwidth of >30 nm in this implementation. A photo-interrupter trigger system supplies the phase information necessary for full determination of the Stokes vector. An Arduino microcontroller performs rapid analysis and displays the results on a liquid crystal display. The polarimeter is compact and can be placed anywhere on an optical table on a single standard post. The components to construct the device are only a fraction of the cost of commercially available devices while the accuracy and precision of the measurements are of the same order of magnitude.

description: We study higher symmetries and anomalies of 4d $\mathfrak{so}(2n_c)$ gauge theory with $2n_f$ flavors. We find that they depend on the parity of $n_c$ and $n_f$, the global form of the gauge group, and the discrete theta angle. The contribution from the fermions plays a central role in our analysis. Furthermore, our conclusion applies to $\mathcal{N}=1$ supersymmetric cases as well, and we see that higher symmetries and anomalies match across the Intriligator-Seiberg duality between $\mathfrak{so}(2n_c)\leftrightarrow\mathfrak{so}(2n_f-2n_c+4)$.

description: Various pulse shape discrimination methods have been used to solve the neutron-gamma discrimination problem. But most of them are limited to off-line calculation due to the computation amount and FPGA performance. In order to realize real time discriminating neutron and gamma, a new algorithm based on the traditional pulse shape discrimination methods was proposed in this paper. The new algorithm takes into account the physical properties of the pulse signal, which greatly reduces the computation and dead time without losing the precision, and can work on FPGA directly. It has a good performance in the actual experiment based on CLLB scintillation detector.

description: Spin canting and complex spin textures in antiferromagnetic materials can often be described in terms of Dzyaloshinskii-Moriya interactions (DMI). Values for DMI parameters are not easily measurable directly, and often inferred from other quantities. In this work, we examine how domain wall dynamics in an antiferromagnetic optomagnonic system can display unique features directly related to the existence of DMI. Our results indicate that the presence of DMI enables spin interactions with cavity photons in a geometry which otherwise allows no magneto-optical coupling, and on the other hand modulates frequencies in a geometry where coupling is already realized in the absence of DMI. This result may be used to measure the DMI constant in optomagnonic experiments by comparing resonances obtained with different polarisations of the exciting field.

description: Mobile and slow moving operations, such as striping, sweeping, bridge flushing and pothole patching, are critical for efficient and safe operation of the highway transportation system. A successfully implemented leader follower autonomous truck mounted attenuators system will eliminate all injuries to DOT employees in follow truck provided appropriate Statutory authority. The leader follower system design imposes more requirements to the lead truck drivers in order to ensure a safe and smooth system operation. The driver is now required to make driving decisions not only from the lead truck's perspective, but also consider the potential implications of his decisions to the follow truck. This project aims to develop a set of rules and clear instructions for ATMA system operation
On program grounding in ASP

Publisher: name: Università degli Studi di Napoli Federico II

description: Answer set programming (ASP) is a declarative problem solving framework introduced by Michael Gelfond and Vladimir Lifschitz in the late ’80s. ASP has received much
attention by researchers for its expressiveness and simpleness so that well-engineered and optimized implementations have been developed for it. However, state-of-the-art answer set solvers have still a strong limitation: they are not be able to reason on nonground programs and then the input program have to be instantiated before the solver can start to reason on it. Consequently,
answer set solvers (i) cannot handle infinite domains and (ii) use huge amounts of memory even if domains are finite. This work wants to give some contribution for these two not trivial problems.
First, I analyze finitary programs as a class of programs that can effectively deal with function symbols and recursion (hence infinite domains and models). Interestingly, even if finitary programs are computationally complete, their restrictions make it possible to keep complexity under control. I study the consequences of relaxing the restrictions on finitary programs and my results enforce a kind of minimality of the properties that characterize finitary programs.
Next, I investigate what happens when we “compose” two programs P and Q belonging to some particular classes that imposing them some restrictions guarantee good computational
properties, so obtaining a program P [ Q that, as a whole, might not be subject to the restrictions of P or Q but that again enjoys good computational properties.
Finally, I study a new approach to tackle the problem (ii) of ASP. The idea is to integrate answer set generation and constraint solving to reduce the memory requirements for a class of multi-sorted logic programs with cardinality constraints: constrained programs. I prove some
theoretical results, introduce provably sound and complete algorithms, and report experimental results on my prototype system for evaluating constrained programs, showing that my approach can solve problem instances with significantly larger domains.

description: We report a study of B -> D*K decays with D* decaying to D pi0 or D gamma, using 383 * 10**6 B Bbar pairs collected at the Upsilon(4S) resonance with the BaBar detector at the SLAC PEP-II B-Factory. The D meson decays under study include a non-CP mode (Kpi), CP-even modes (K+K-, pi^+pi^-) and CP-odd modes (KS pi0, KS phi, KS omega). We measure ratios (R*_{CP+-}) of branching fractions of decays to CP eigenmode states and to flavor-specific states as well as CP asymmetries (A*_{CP+-}). These measurements are sensitive to the unitarity triangle angle gamma. We obtain A*_{CP+} = -0.11 pm 0.09 pm 0.01, R*_{CP+} = ~1.31 pm 0.13 pm 0.04, and A*_{CP-} = 0.06 pm 0.10 pm 0.02, R*_{CP-} = ~1.10 pm 0.12 pm 0.04, where the first error is statistical and the second error is systematic. Translating our results into an alternative parametrization, widely used for related measurements, we obtain x*_{+}=0.11 pm 0.06 pm 0.02 and x*_{-} = 0.00 pm 0.06 pm 0.02. No significant CP-violating charge asymmetry is found in either the flavor-specific mode D -> K pi or in B -> D* pi decays.

description: There has been a growing interest in ultra-high purity, low-background NaI(Tl) crystals for dark matter direct searches. Past research indicates that zone refining is an efficient and scalable way to purify NaI. In particular, K and Rb -- two elements with radioisotopes that can cause scintillation backgrounds -- can be efficiently removed by zone refining. However, zone refining has never been demonstrated for ultra-high purity NaI which became commercially available recently. In this article, we show that many common metallic impurities can be efficiently removed via zone refining. A numerical model for predicting the final impurity distribution was developed and used to fit the ICP-MS measurement data to determine the segregation coefficient and the initial concentration. Under this scheme, the segregation coefficient for K is estimated to be 0.57, indicating that zone refining is still effective in removing K from ultra-high purity NaI. As zone refining tends to move the impurities to one end, elements with concentrations too low to be measured directly in the unprocessed powder can potentially be detected in the end due to the enrichment. We also present an analysis technique to estimate the initial concentrations of impurities with partial data, which effectively enhances the sensitivity of the spectrometer. Using this technique, the initial concentration of $^{85}$Rb is estimated to be between 5 ppt and 14 ppt at 90% CL, at least 14 times lower than the detection limit of ICP-MS and 7 times lower than the current most stringent limit set by the DAMA collaboration by direct counting of radioactive $^{87}$Rb. These results imply that zone refining is a key technique in developing next-generation, NaI-based crystal scintillators for dark matter direct detection.

description: We study the localization of bosonic atoms in an optical lattice, which interact in a spatially confined region. The classical theory predicts that there is no localization below a threshold value for the strength of interaction that is inversely proportional to the number of participating atoms. In a full quantum treatment, however, we find that localized states exist for arbitrarily weak attractive or repulsive interactions for any number ($>1$) of atoms. We further show, using an explicit solution of the two-particle bound state and an appropriate measure of entanglement, that the entanglement tends to a finite value in the limit of weak interactions. Coupled with the non-existence of localization in an optimized quantum product state, we conclude that the localization exists by virtue of entanglement.

description: Organizing complex peer production projects and advancing scientific knowledge of open collaboration each depend on the ability to measure quality. Article quality ratings on English language Wikipedia have been widely used by both Wikipedia community members and academic researchers for purposes like tracking knowledge gaps and studying how political polarization shapes collaboration. Even so, measuring quality presents many methodological challenges. The most widely used systems use labels on discrete ordinal scales when assessing quality, but such labels can be inconvenient for statistics and machine learning. Prior work handles this by assuming that different levels of quality are "evenly spaced" from one another. This assumption runs counter to intuitions about the relative degrees of effort needed to raise Wikipedia encyclopedia articles to different quality levels. Furthermore, models from prior work are fit to datasets that oversample high-quality articles. This limits their accuracy for representative samples of articles or revisions. I describe a technique extending the Wikimedia Foundations' ORES article quality model to address these limitations. My method uses weighted ordinal regression models to construct one-dimensional continuous measures of quality. While scores from my technique and from prior approaches are correlated, my approach improves accuracy for research datasets and provides evidence that the "evenly spaced" assumption is unfounded in practice on English Wikipedia. I conclude with recommendations for using quality scores in future research and include the full code, data, and models.

Modulo the Miura group, such deformations are unique. The requirement that any hydrodynamic reduction possesses a deformation of this kind imposes strong constraints on the structure of dispersive terms, suggesting an alternative approach to the integrability in 2+1 dimensions.

L'introduzione è articolata in due sezioni: nella prima è offerta una ricognizione della bibliografia critica sull’Ottimo commento; nella seconda si affrontano le numerose e problematiche questioni (datazione, rapporto con la precedente tradizione esegetica sulla Commedia, in particolare con le altre forme dell’Ottimo commento, prassi compilatoria del redattore) relative alla cosiddetta terza redazione.

Lat. 3201, e il Pierpont Morgan M676) che tramandano il testo del commento a Purgatorio e Paradiso, cui segue una ricostruzione dei loro rapporti genealogici e una plausibile soluzione stemmatica. è offerta, inoltre, una disamina della stratigrafia linguistica, con individuazione dei tratti meridionali, di uno dei menanti del codice Barb. Lat. 4103, che colmò gli spazi bianchi lasciati dal primo copista. Un paragrafo è poi dedicato ad alcune chiose singulares vergate dal copista del codice Pierpont Morgan M676, in parte riconducibili alla tradizione del cosiddetto Anonimo Lombardo. Il testo critico, infine, è corredato da una doppia fascia di apparato, ecdotico a piè di pagina, ed esegetico in chiusura di ogni singolo canto, dove si specificano le fonti citate nel commento e l’eventuale ascendente esegetico di riferimento per ogni singola glossa.

description: A definite form for the boundary term that produces the finiteness of both the conserved quantities and Euclidean action for any Lovelock gravity with AdS asymptotics is presented. This prescription merely tells even from odd bulk dimensions, regardless the particular theory considered, what is valid even for Einstein-Hilbert and Einstein-Gauss-Bonnet AdS gravity. The boundary term is a given polynomial of the boundary extrinsic and intrinsic curvatures (also referred to as Kounterterms series). Only the coupling constant of the boundary term changes accordingly, such that it always preserves a well-posed variational principle for boundary conditions suitable for asymptotically AdS spaces. The background-independent conserved charges associated to asymptotic symmetries are found. In odd bulk dimensions, this regularization produces a generalized formula for the vacuum energy in Lovelock AdS gravity. The standard entropy for asymptotically AdS black holes is recovered directly from the regularization of the Euclidean action, and not only from the first law of thermodynamics associated to the conserved quantities.

description: We make a detailed analysis of error mechanisms, gate fidelity, and scalability of proposals for quantum computation with neutral atoms in addressable (large lattice constant) optical lattices. We have identified possible limits to the size of quantum computations, arising in 3D optical lattices from current limitations on the ability to perform single qubit gates in parallel and in 2D lattices from constraints on laser power. Our results suggest that 3D arrays as large as 100 x 100 x 100 sites (i.e., $\sim 10^6$ qubits) may be achievable, provided two-qubit gates can be performed with sufficiently high precision and degree of parallelizability. Parallelizability of long range interaction-based two-qubit gates is qualitatively compared to that of collisional gates. Different methods of performing single qubit gates are compared, and a lower bound of $1 \times 10^{-5}$ is determined on the error rate for the error mechanisms affecting $^{133}$Cs in a blue-detuned lattice with Raman transition-based single qubit gates, given reasonable limits on experimental parameters.

description: The HMW effect in non-commutative quantum mechanics is studied. By solving the Dirac equations on non-commutative (NC) space and non-commutative phase space, we obtain topological HMW phase on NC space and NC phase space respectively, where the additional terms related to the space-space and momentum-momentum non-commutativity are given explicitly.

description: Split matroids form a minor-closed class of matroids, and are defined by placing conditions on the system of split hyperplanes in the matroid base polytope. They can equivalently be defined in terms of structural properties involving cyclic flats. We confirm a conjecture of Joswig and Schröter by proving an excluded-minor characterisation of the class of split matroids.

Slitless spectroscopy : from objective prism films to grism CCD
Creators: name: Armond, Ana Cristina (Tina)
Publisher: name: Zenodo
Year: 2019

description: Slitless spectroscopy has been a tool to search for Halpha emission-line stars for the past 60 years.

I was part of a team using this technique with objective prism films obtained at the ESO 1 m Schmidt telescope at La Silla in the 90's. The films were 30cm x 30cm, corresponding to a field of view of 5o x 5o in the sky. They were inspected with a binocular microscope and an Halpha emission strength were assigned by eye to each star.

Results of this work are shown in Reipurth et al (2004 AJ 127,1117) and Pettersson et al (2014, A&A 570,A30).

Now, as an astronomer at the SOAR Telescope for a few years, I figured how to use the Goodman spectrograph grisms in slitless mode, in order to continue to search for young stars. The field of view here is much smaller (7' x 7'), but the use of CCD images enable us to measure Halpha equivalent widths.

In my observations of small star forming regions I have found so far more than 500 new emission-line stars. I will compare both methods and results.
Automatic Assembly Planning based on Digital Product Descriptions

description: This paper proposes a new concept in which a digital twin derived from a digital product description will automatically perform assembly planning and orchestrate the production resources in a manufacturing cell. Thus the manufacturing cell has generic services with minimal assumptions about what kind of product will be assembled, while the digital product description is designed collaboratively between the designer at an OEM and automated services at potential manufacturers. This has several advantages. Firstly, the resulting versatile manufacturing facility can handle a broad variety of products with minimal or no reconfiguration effort, so it can cost-effectively offer its services to a large number of OEMs. Secondly, a solution is presented to the problem of performing concurrent product design and assembly planning over the organizational boundary. Thirdly, the product design at the OEM is not constrained to the capabilities of specific manufacturing facilities. The concept is presented in general terms in UML and an implementation is provided in a 3D simulation environment using Automation Markup Language for digital product descriptions. Finally, two case studies are presented and applications in a real industrial context are discussed.
Analisi dei Meccanismi Molecolari di Citoprotezione in Risposta allo Stimolo Ipossico

description: Abbiamo esplorato i meccanismi molecolari coinvolti nella protezione indotta dal precondizionamento ischemico (PC) tardivo in cellule endoteliali. Il PC tardivo protegge le cellule endoteliali dalla morte indotta da ipossia prolungata mediante meccanismi molecolari dipendenti da protein chinasi A e fosfatidil-inositolo-3-chinasi. Entrambi i pathway determinano l' attivazione di Akt, che gioca un ruolo chiave nella citoprotezione PC-mediata.

description: Herdmania pennata (Monniot C. & Monniot F., 1991) (Fig. 50A) Pyura pennata Monniot C. & Monniot F., 1991: 412, fig. 28. MATÉRIEL EXAMINÉ. — Nouvelle-Calédonie. Ride de Norfolk, 23°43'S, 168°22'E, 230 m, 22.VI.2001, 1 spécimen; 19°07.91'S, 163°29.38'E, 190 m, 19.VI.1991, 1 spécimen. Le plus grand spécimen, de 16 mm de diamètre, a une tunique molle, un peu transparente, nue sauf quelques particules sédimentaires adhérentes (Fig. 50A). Les siphons sont sessiles. Les muscles radiaires étaient teintés de rouge. Ils se disposent en quelques gros rubans peu étendus sur les faces latérales du corps. La structure interne correspond exactement à ce qui a déjà été décrit pour des exemplaires récoltés dans la même région à une profondeur équivalente. La branchie a huit plis à gauche et neuf à droite. De chaque côté, en position postérieure, se situe une gonade allongée, rectiligne formée d'un ovaire bordé de chaque côté de lobules testiculaires en petits bouquets. Chacun de ces lobules émet un court canal qui rejoint le spermiducte commun axial. Sur toute la longueur du spermiducte commun, de petites papille mâles dressées sont alignées. La papille femelle est simple et distale. Les spicules sont semblables à ceux des autres espèces du genre Herdmania, très courts dans la tunique et allongés dans tous les organes internes. REMARQUES La présence de spicules dans cette espèce nous incite à la placer dans le genre Herdmania qui ne contient que des espèces à spicules, plutôt que dans le genre proche Pyura où il n'y a pas de spicules. Herdmania pennata est proche de H. polyducta (Monniot C. & Monniot F., 1989), mais cette dernière a des rhizoïdes sur la tunique, un foie en trois parties au lieu de deux, un anus lobé, mais surtout un testicule qui couvre totalement l'ovaire, sans spermiducte commun mais de nombreuses papilles mâles dispersées, indépendantes les unes des autres.

description: We study the constraints on gravity scale $M_P$ in extra-dimension gravitational theory, obtained from gravity-induced processes. The obtained constraints are subdivided into strong (though not robust) and reliable (though less strong). The strong constraints can be in principle relaxed due to some broken gauge symmetries, e.g. family symmetry. The strongest constraint is given by neutrino oscillations. For different assumptions the lower bound on $M_P$ is $10^{15} - 10^{18}$ GeV. However, it can be, in principle, reduced by broken family symmetry. More reliable bounds are due to flavor-conserved operators or those which change the flavors within one family. These bounds, obtained using the electron mass and width of $π\to eν$ decay, are $1\times 10^5$ GeV and $5\times 10^5$ GeV, for these two cases, respectively.
