description: Facebook News Feed personalization algorithm has a significant impact, on a daily basis, on the lifestyle, mood and opinion of millions of Internet users. Nonetheless, the behavior of such algorithms usually lacks transparency, motivating measurements, modeling and analysis in order to understand and improve its properties. In this paper, we propose a reproducible methodology encompassing measurements and an analytical model to capture the visibility of publishers over a News Feed. First, measurements are used to parameterize and to validate the expressive power of the proposed model. Then, we conduct a what-if analysis to assess the visibility bias incurred by the users against a baseline derived from the model. Our results indicate that a significant bias exists and it is more prominent at the top position of the News Feed. In addition, we found that the bias is non-negligible even for users that are deliberately set as neutral with respect to their political views.

description: The production of the \sm\ Higgs $ϕ$ with intermediate mass at the proposed CERN LEP$\otimes$LHC $ep$ collider in $γq(\bar q)\rightarrow W^\pmϕq'(\bar q')$, $γq(\bar q)\rightarrow Z^0ϕq(\bar q)$ and $gγ\rightarrow q\bar qϕ$ events is studied. This is done for all possible (massive) flavours of the quarks $q(q')$ and using photons generated via Compton back--scattering of laser light. We study signatures in which the Higgs decays to $b\bar b$--pairs and the electroweak vector bosons $W^\pm$ and $Z^0$ decay either hadronically or leptonically. All possible backgrounds to these signals are also computed. Flavour identification on $b$--jets is assumed. Explicit formulae for the helicity amplitudes of the above processes are given.

description: Several cosmologically distant astrophysical sources may produce high-energy cosmic neutrinos (E \geq 10^6 GeV) of all flavors above the atmospheric neutrino background. We study the effects of vacuum neutrino mixing in three flavor framework on this cosmic neutrino flux. We also consider the effects of possible mixing between the three active neutrinos and the (fourth) sterile neutrino with or without Big-Bang nucleosynthesis constraints and estimate the resulting final high-energy cosmic neutrino flux ratios on earth compatible with currently existing different neutrino oscillation hints in a model independent way. Further, we discuss the case where the intrinsic cosmic neutrino flux does not have the standard ratio.

Higher Spin Currents with Manifest $SO(4)$ Symmetry in the Large ${\cal N}=4$ Holography

Year: 2018
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The large ${\cal N}=4$ nonlinear superconformal algebra is generated by six spin-$1$ currents, four spin-$\frac{3}{2}$ currents and one spin-$2$ current. The simplest extension of these $11$ currents is described by the $16$ higher spin currents of spins $(1,\frac{3}{2},\frac{3}{2}, \frac{3}{2}, \frac{3}{2}, 2,2,2,2,2,2, \frac{5}{2}, \frac{5}{2},\frac{5}{2}, \frac{5}{2}, 3)$. In this paper, by using the defining operator product expansions (OPEs) between the $11$ currents and $16$ higher spin currents, we determine the $16$ higher spin currents (the higher spin-$1, \frac{3}{2}$ currents were found previously) in terms of affine Kac-Moody spin-$\frac{1}{2}, 1$ currents in the Wolf space coset model completely. An antisymmetric second rank tensor, three antisymmetric almost complex structures or the structure constant are contracted with the multiple product of spin-$\frac{1}{2}, 1$ currents. The Wolf space coset contains the group $SU(N+2)$ and the level $k$ is characterized by the affine Kac-Moody spin-$1$ currents. After calculating the eigenvalues of the zeromode of the higher spin-$3$ current acting on the higher representations up to three (or four) boxes of Young tableaux in $SU(N+2)$ in the Wolf space coset, we obtain the corresponding three-point functions with two scalar operators at finite $(N,k)$. Furthermore, under the large $(N,k)$ 't Hooft like limit, the eigenvalues associated with any boxes of Young tableaux are obtained and the corresponding three-point functions are written in terms of the 't Hooft coupling constant in simple form in addition to the two-point functions of scalars and the number of boxes.

description: Road Extraction from satellite imagery plays a crucial role in various applications ranging from urban planning to traffic monitoring and infrastructure development. In this project, we propose a method for road extraction using satellite images, aiming to produce clear and accurate representations of road networks. The process begins with acquiring high-resolution satellite images covering the target area. These images are preprocessed to enhance their quality and reduce noise, ensuring optimal input for subsequent analysis. Next, we employ advanced image processing techniques and machine learning algorithms to extract road features from the satellite imagery. One of the key steps in our approach is feature extraction, where we identify distinct characteristics associated with roads such as color, texture, and spatial patterns. By leveraging convolutional neural networks (CNNs) and other deep learning architectures, we train models to recognize these features and distinguish roads from other elements in theimages. Once the road features are detected, we employ segmentation algorithms to separate the roads from the surrounding environment effectively. This segmentation process involves delineating the boundaries of road networks, ensuring that the extracted roads align accurately with their real-world counterparts. Furthermore, to enhance the visual representation of the extracted roads, we implement highlighting techniques that emphasize the road features in the satellite images. This enhancement not only improves the visibility of roads but also facilitates their interpretation and analysis by end-users. The effectiveness of our approach is evaluated through extensive experimentation on diverse satellite imagery datasets covering various geographic regions and environmental conditions. Quantitative metrics such as precision, recall, and F1-score are utilized to assess the accuracy of road extraction results. Overall, our project demonstrates a robust and efficient method for road extraction from satellite images, offering valuable insights for urban planning, transportation management, and disaster response. By providingaccurate and detailed road maps derived from satellite imagery, our approach contributes to improving decision-making processes and enhancing the efficiency of various applications reliant on spatial data analysis.
Impact of planetesimal eccentricities and material strength on the appearance of eccentric debris disks

description: Context: Since circumstellar dust in debris disks is short-lived, dust-replenishing requires the presence of a reservoir of planetesimals. These planetesimals in the parent belt of debris disks orbit their host star and continuously supply the disk with fine dust through their mutual collisions. Aims: We aim to understand effects of different collisional parameters on the observational appearance of eccentric debris disks. Methods: The collisional evolution of selected debris disk configurations was simulated with the numerical code ACE. Subsequently, selected observable quantities are simulated with our newly developed code DMS. The impact of the eccentricity, dynamical excitation, and the material strength is discussed with respect to the grain size distribution, the spectral energy distribution, and spatially resolved images of debris disk systems. Results: The most recognizable features in different collisional evolutions are as follows. First, both the increase of dynamical excitation in the eccentric belt of the debris disk system and the decrease of the material strength of dust particles result in a higher production rate of smaller particles. This reduces the surface brightness differences between the periastron and the apastron sides of the disks. For very low material strengths, the "pericenter glow" phenomenon is reduced and eventually even replaced by the opposite effect, the "apocenter glow". Second, it is possible to constrain the level of collisional activity from the appearance of the disk, for example, the wavelength-dependent apocenter-to-pericenter flux ratio. Within the considered parameter space, the impact of the material strength on the appearance of the disk is stronger than that of dynamical excitation of the system. Finally, we find that the impact of the collisional parameters on the net spectral energy distribution is weak.

description: We propose a new and universal approach to the hadronization problem that incorporates both partonic and hadronic degrees of freedom in their respective domains of relevance, and that describes the conversion between them within a kinetic field theory formulation in real time and full 7-dimensional phase space. We construct a scale-dependent effective theory that reduces to perturbative QCD with its scale and chiral symmetry properties at short space-time distances, but at large distances (r > 1 fm) yields symmetry breaking gluon and quark condensates plus hadronic excitations. The approach is applied to the evolution of fragmenting qq~ and gg jet pairs as the system evolves from the initial 2-jet configuration, via parton showering and cluster formation, to the final yield of hadrons. The phenomenological implications for e+e- -> hadrons are investigated, such as the time scale of the transition, and its energy dependence, cluster size and mass distributions. We compare our results for particle production and Bose-Einstein correlations with experimental data, and find an interesting possibility of extracting the basic parameters of the space-time evolution of the system from Bose enhancement measurements.

description: With the experimental data collected by the ALICE collaboration in Pb-Pb collisions at a center-of-mass energy per nucleon pair 2.76 TeV for six different centralities (0-5$\%$, 5-10$\%$, 10-20$\%$, 20-40$\%$, 40-60$\%$ and 60-80$\%$), we investigate the scaling property of the pion, kaon and proton transverse momentum ($p_{\rm{T}}$) spectra at these centralities. We show that in the low $p_{\rm{T}}$ region with $p_{\rm T} \leq$ 2.75 (3.10 and 2.35) GeV/c the pion (kaon and proton) spectra exhibit a scaling behaviour independent of the centrality of the collisions. This scaling behaviour arises when these spectra are presented in terms of a suitable variable, $z=p_{\rm{T}}/K$. The scaling parameter $K$ is determined by the quality factor method and is parameterized by $a \langle N_{\rm{part}}\rangle^{b}$, where $\langle N_{\rm{part}}\rangle$ is the average value of the number of participating nucleons, $a$ and $b$ are free parameters, $b$ characterizes the rate at which $\textrm{ln} K$ changes with $\textrm{ln} \langle N_{\rm{part}}\rangle$. The values of $b$ for pions and kaons are consistent within uncertainties, while they are smaller than that for protons. In the high $p_{\rm{T}}$ region, due to the suppression of the spectra, a violation of the proposed scaling is observed going from central to peripheral collisions. The more peripheral the collisions are, the more clearly violated the proposed scaling becomes. In the framework of the colour string percolation model, we argue that the pions, kaons and protons originate from the fragmentation of clusters which are formed by strings overlapping and the cluster's fragmentation functions are different for different hadrons. The scaling behaviour of the pion, kaon and proton spectra in the low $p_{\rm T}$ region can be simultaneously explained by the colour string percolation model in a qualitative way.

description: Fish farming contributes significantly to food security, job creation and improved state revenue. For this, it should be encouraged, with as a development strategy, consideration of the realities of the environments, research towards adapted fish farming and permanent consideration of the constraints hindering the development of the sector..This will allow the population to move towards sustainable fish farming. Despite all these advantages, this activity remains in its embryonic state. In most regions, particularly in the Urban Commune of Kankan. In this Municipality it results in the establishment of fish ponds and its development remains uncertain. Practitioners of this activity in the Urban Commune of Kankan are faced with certain management problems of their fish farming sites. Among these problems we must mention: insufficient food for fish.

The objective of this study was to analyze the situation of fish farming in the Urban Commune of Kankan with a view to proposing new guidelines to increase the production yield of fish farmers.

The interview conducted with executives and the analysis of the archives of the Urban Commune of Kankan, allowed us to know the 8 actors who distribute the 87 installed basins, 76 of which are functional and 11 non-functional; the survey of stakeholders allowed us to know the different species of fish raised by fish farmers, among these species we have: Oreochromis niloticus, Clarias gariepinus and Heterobrancus longifilus; the survey concerning the identification and characterization of fish farming sites revealed that 87.5% of stakeholders use concrete ponds, i.e. 7 fish farmers, compared to 12.5% who use tank ponds, i.e. 1 fish farmer; as for the identification of the constraints linked to fish farming eight (8) constraints were identified among which we have: lack of food for the fish, lack of means of financing and materials.

description: The lepton asymmetry that could be generated in the early universe through oscillations of active to sterile neutrinos is calculated (almost) analytically for small mixing angles, sin 2θ< 10^{-2}. It is shown that for a mass squared difference, δm^2=-1 eV^2 it may rise at most by 6 orders of magnitude from the initial ``normal'' value of 10^{-10}, since the back-reaction from the refraction index terminates this rise while the asymmetry is still small. Only for very large mass differences, δm^2 about 10^9 eV^2, the lepton asymmetry could reach a significant magnitude exceeding 0.1.

description: This paper presents a framework for automatically learning shape and appearance models for medical (and certain other) images. It is based on the idea that having a more accurate shape and appearance model leads to more accurate image registration, which in turn leads to a more accurate shape and appearance model. This leads naturally to an iterative scheme, which is based on a probabilistic generative model that is fit using Gauss-Newton updates within an EM-like framework. It was developed with the aim of enabling distributed privacy-preserving analysis of brain image data, such that shared information (shape and appearance basis functions) may be passed across sites, whereas latent variables that encode individual images remain secure within each site. These latent variables are proposed as features for privacy-preserving data mining applications. The approach is demonstrated qualitatively on the KDEF dataset of 2D face images, showing that it can align images that traditionally require shape and appearance models trained using manually annotated data (manually defined landmarks etc.). It is applied to MNIST dataset of handwritten digits to show its potential for machine learning applications, particularly when training data is limited. The model is able to handle ``missing data'', which allows it to be cross-validated according to how well it can predict left-out voxels. The suitability of the derived features for classifying individuals into patient groups was assessed by applying it to a dataset of over 1,900 segmented T1-weighted MR images, which included images from the COBRE and ABIDE datasets.

description: We propose a scheme of fast three-qubit Toffoli quantum gate for ultracold neutral-atom qubits. The scheme is based on the Stark-tuned three-body Förster resonances, which we have observed in our recent experiment [D.B.Tretyakov et al., Phys.Rev.Lett. 119, 173402 (2017)]. The three-body resonance corresponds to a transition when the three interacting atoms change their states simultaneously, and it occurs at a different dc electric field with respect to the two-body Förster resonance. A combined effect of three-body and two-body Förster interactions in external electric and magnetic fields near the three-body resonance results in complex coherent behavior of the populations and phases of collective states of a three-atom system. We have found that it is possible to obtain experimental conditions suitable to implement three-qubit Toffoli gate with 96.8\% fidelity and less than 3~$μ$s duration.

description: Superconductors, an essential class of functional materials, hold a vital position in both fundamental science and practical applications. However, most superconductors, including MgB$_2$, Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$, and FeSe, are highly sensitive to environmental attacks (such as water and moist air), hindering their wide applications. More importantly, the surface physical and chemical processes of most superconductors in various environments remain poorly understood. Here, we comprehensively investigate the high resistance of superconducting titanium nitride (TiN) epitaxial films against acid and alkali attacks. Unexpectedly, despite immersion in acid and alkaline solutions for over 7 days, the crystal structure and superconducting properties of TiN films remain stable, as demonstrated by high-resolution X-ray diffraction, electrical transport, atomic force microscopy, and scanning electron microscope. Furthermore, combining scanning transmission electron microscopy analysis with density functional theory calculations revealed the corrosion mechanisms: acid corrosions lead to the creation of numerous defects due to the substitution of Cl ions for N anions, whereas alkaline environments significantly reduce the film thickness through the stabilization of OH$^\ast$ adsorbates. Our results uncover the unexpected stability and durability of superconducting materials against environmental attacks, highlighting their potential for enhanced reliability and longevity in diverse applications.

description: The fluctuation determinant which determines the preexponential factor of the transition rate for minimal bubbles is computed for the electroweak theory with $\sin Θ_W = 0$. As the basic action we use the three-dimensional high-temperature action including, besides temperature dependent masses, the $T Φ^3$ one-loop contribution which makes the phase transition first order. The results show that this contribution (which has then to be subtracted from the exact result) gives the dominant contribution to the one-loop effective action. The remaining correction is of the order of, but in general larger than the critical bubble action and suppresses the transition rate. The results for the Higgs field fluctuations are compared with those of an approximate heat kernel computation of Kripfganz et al., good agreement is found for small bubbles, strong deviations for large thin-wall bubbles.

description: Leptogenys (Lobopelta) conigera Mayr, r. Adlerzi nov. st.
- [[worker]], - Long. 6,4 a 7,5 mill. - Differe de la forme typique, a laquelle elle ressemble enormement, sauf pour la taille, par ses antennes dont le scape depasse l'occiput de 1 / 8 a peine de sa longueur et par les articles 8 a 10 du funicule aussi larges que longs (plus longs que larges chez le type de l'espece). Pas de reflet. La suture meso-metanotale est obsolete, a peine indiquee. Le n oe ud du pedicule est seulement deux fois plus long que sa largeur posterieure (plus long chez le type et surtout chez la race mutans). Pilosite un peu plus fine et moins abondante que chez le type.
Townsville, Queensland (Turner) et Charter Towers, Ost Queensland (Wiederkehr). Chez ces derniers exemplaires, le n oe ud du pedicule est plus eleve, surtout devant.
On peut dire que la forme typique, decrite par Mayr, est intermediaire entre les races mutans et Adlerzi qui, si on ne la connaissait pas, devraient constituer deux especes.

description: Ni-rich layered cathode LiNi0.8Mn0.1Co0.1O2 (NMC811) have been facing serious structural issues including high degree of Li/Ni mixing and poor surface stability, which lead to poor electrochemical cycling performances compared to other layered cathode with lower Ni content. Various surface coatings have been investigated to enhance the electrochemical performances of Ni-rich cathode. While, most work focus on the materials and methods of coating, and few has explored the subtle structural variations of cathode particles after coating. In this work, Li2ZrO3 coating induced structural variations of NMC811 have been carefully investigated. Ordered occupancy of Ni in Li slab with reduced Li/Ni mixing degree is firstly discovered after Li2ZrO3 coating. Moreover, the O–O distance becomes longer with less active O on surface, which can greatly suppress surface side reactions at high potentials. The obtained large reversible capacity and excellent capacity retention can be ascribed to the subtle structural variations of NMC811 after Li2ZrO3 coating.

description: We present here a self-consistent, tridimensional model of a disc galaxy composed by a number of ellipsoidal distributions of matter having different flattening and density profile. The model is self-consistent and takes into account the observed luminosity distribution, the flattening profile and the stellar rotation- and velocity dispersion- curves. In this paper we considered the particular case of a disc galaxy composed by two spheroidal bodies: an exponential disc and a bulge following the r^{1/4} law. We studied the behavior of the stellar rotation- and velocity dispersion- profiles along the sequence of S0s and Spirals, identified by an increasing disc-to-bulge ratio. Inside every class, kinematic curves were produced by changing the relative concentration of the two components and the inclination of the galaxy with respect to the line of sight. The comparison with observational data requires only two scaling factors: the total mass of the galaxy, and the effective radius. The model allows also to detect the presence of anisotropy in the velocity distribution. In the special case of S0s, we explored the sensitivity of the kinematics of the model by changing the anisotropy and the flattening of the bulge. For intermediate flattening (0.4

description: Observations show that winds can be driven from the innermost region (inside a 50 Schwarschild radius) of a thin disk. It is interesting to study the winds launched from the innermost region. A hot corona above the black hole (BH) thin disk is irradiated by the disk. We perform two-dimensional hydrodynamical simulations to study the winds driven by radiation force from the corona in the innermost regions. The hard X-ray spectrum from active galactic nuclei (AGNs) suggests that the corona temperature is about $10^9$ K, so that we mainly analyze the properties of winds (or outflows) from the $10^9$ K corona. The disk luminosity plays an important role in driving the outflows. The more luminous the disk, the stronger the outflows. Mass outflow rate ($\dot{M}_{\rm out}$) at a 90 Schwarschild radius depends on disk luminosity, which can be described as $\dot{M}_{\rm out}\propto 10^{3.3 Γ}$ ($Γ$ is the ratio of the disk luminosity to the Eddington luminosity). In the case of high luminosity (e.g. $Γ=0.75$), the supersonic outflows with maximum speed $1.0 \times 10^4$ Km s$^{-1}$ are launched at $\sim17^{o}$ --$30^{o}$ and $\sim50^{o}$ --$80^{o}$ away from the pole axis. The Bernoulli parameter keeps increasing with the outward propagation of outflows. The radiation force keeps accelerating the outflows when outflows move outward. Therefore, we can expect the outflows to escape from the BH gravity and go to the galactic scale. The interaction between outflows and interstellar medium may be an important AGN feedback process.

description: We numerically calculate two-particle correlation functions of CERN-SPS 158 A GeV Pb+Pb central collisions based on a (3+1)-dimensional relativistic hydrodynamics with a first order phase transition. We analyze the pair momentum dependence of pion source sizes extracted from the Yano-Koonin-Podgoretski\uı (YKP) parametrization which is expected to give the source sizes directly. We find that, even in the case of the first order phase transition, the collective expansion and surface dominant freeze-out of the fluid naturally lead to the opaque source for which the interpretation of the temporal source parameter as the emission duration breaks down.
