description: It has been a long-standing question whether fossil groups are just sampling the tail of the distribution of ordinary groups, or whether they are a physically distinct class of objects, characterized by an unusual and special formation history. To study this question, we here investigate fossil groups identified in the hydrodynamical simulations of the GIMIC project, which consists of resimulations of five regions in the Millennium Simulation (MS) that are characterized by different large-scale densities, ranging from a deep void to a proto-cluster region. For comparison, we also consider semi-analytic models built on top of the MS, as well as a conditional luminosity function approach. We identify galaxies in the GIMIC simulations as groups of stars and use a spectral synthesis code to derive their optical properties. The X-ray luminosity of the groups is estimated in terms of the thermal bremsstrahlung emission of the gas in the host halos, neglecting metallicity effects. We focus on comparing the properties of fossil groups in the theoretical models and observational results, highlighting the differences between them, and trying to identify possible dependencies on environment for which our approach is particularly well set-up. We find that the optical fossil fraction in all of our theoretical models declines with increasing halo mass, and there is no clear environmental dependence. Combining the optical and X-ray selection criteria for fossil groups, the halo mass dependence of the fossil groups seen in optical vanishes. Over the GIMIC halo mass range we resolve best, 9.0\times1012 \sim 4.0\times1013 h-1 M, the central galaxies in the fossil groups show similar properties as those in ordinary groups, in terms of age, metallicity, color, concentration, and mass-to-light ratio.

description: In the aftermath of the crisis conventionally started with the Lehman’s default, which echoed even in Europe and over the most fragile areas in the Mediterranean area SMEs in the South of Italy addressed peculiar growing pathways. Thanks to a research project in which three university from the Campania region and a number of interviewers have been involved, the article criticizes delegation processes occurred during growth phases. Delegation, meant as the critical factor of success within dimensional development and structuration processes (e.g. as explained by Chandler in 1962) represents the crossroad from a small firm paternally lead to a medium enterprise. In this article, delegation-dimension will be presented through the different representation tied to formality-informality, with the aim of exploring threats and opportunities of both.

description: We present the near light cone Hamiltonian $H$ in lattice QCD depending on the parameter $η$, which gives the distance to the light cone. Since the vacuum has zero momentum we can derive an effective Hamiltonian $H_{eff}$ from $H$ which is only quadratic in the momenta and therefore solvable by standard methods. An approximate ground state wave functional is determined variationally in the limit $η\to 0$.

description: We present a novel slowing scheme for beams of laser-coolable diatomic molecules reminiscent of Zeeman slowing of atomic beams. The scheme results in efficient compression of the 1-dimensional velocity distribution to velocities trappable by magnetic or magneto-optical traps. 3D Monte Carlo simulations for the prototype molecule $^{88}\mathrm{Sr}^{19}\mathrm{F}$ and experiments in an atomic testbed demonstrate a performance comparable to traditional atomic Zeeman slowing and an enhancement of flux below v=35 m/s by a factor of $\approx 20$ compared to white-light slowing. This is the first experimentally shown continuous and dissipative slowing technique in molecule-like level structures, promising to provide the missing link for the preparation of large ultracold molecular ensembles.

description: A meta-analysis indicated that clinical depression was associated with several large alterations in cellular immunity. Analyzing only methodologically sound studies, reliable immune alterations included lowered proliferative response of lymphocytes to mitogens (effect size rs = .24-.45), lowered natural killer cell activity (r = .28), and alterations in numbers of several white blood cell populations (rs = .11-.77). Immune alterations were greater in both older and hospitalized samples. There was also evidence of a linear relation between intensity of depressive affect and indicators of cellular immunity. Estimates of sample sizes needed to detect reliable effects for each immune outcome are provided. How neuroendocrine mechanisms or health practices might link depression to immunity is discussed, and design features needed to better understand these pathways are specified.

description: Starting from the stochastic equation for the density operator, we formulate the exact (instantaneous) stress tensor for interacting Brownian particles, whose average value agrees with expressions derived previously. We analyze the relation between the stress tensor and forces on external potentials, and observe that, out of equilibrium, particle currents give rise to extra forces. Next, we derive the stress tensor for a Landau-Ginzburg theory in non-equilibrium situations, finding an expression analogous to that of the exact microscopic stress tensor, and discuss the computation of out-of-equilibrium (classical) Casimir forces. We use these relations to study the spatio-temporal correlations of the stress tensor in a Brownian fluid, which we derive exactly to leading order in the interaction potential strength. We observe that, after integration over time, the spatial correlations generally decay as power laws in space. These are expected to be of importance for driven confined systems. We also show that divergence-free parts of the stress tensor do not contribute in the Green-Kubo relation for the viscosity.

description: This research investigated the effect of Carbon Fibre Reinforced Polymer (CFRP) strengthening on the axial capacity and ductility of non-slender square concrete columns. There is a problem of buildings collapsing in Kenya. Retrofitting of the buildings vulnerable to collapse is of great importance to ensure the safety of the occupants and to address the housing deficit in the country. An experimental research programme was conducted on 95 non-slender square concrete columns to find out the gain in axial capacity and ductility of the columns strengthened by CFRP. The specimens (150mm x 150mm x 350mm) were made of plain and reinforced concrete. Three different concrete grades: C8/10, C12/15 and C16/20 were used. The specimen had varying configurations of CFRP wrap: partial and full confinement in one and two layers. Four parameters are investigated in this study: concrete grade, steel reinforcement, degree of confinement and the number of layers of CFRP wrap. The specimens were subjected to uniaxial compression up to failure, and the stress-strain curves were plotted. This study found that the weakest concrete grade experiences the highest effect due to CFRP strengthening. Concrete C8/10 was 5.42 times more affected than Concrete C16/20 in terms of axial capacity (542%) but the effect was comparable in terms of ductility. Plain concrete specimens experienced higher effect in both axial capacity (114%) and ductility (145%) than reinforced concrete specimens. Full confinement was more effective in both the axial capacity (383%) and ductility (275%). Similarly, two layers was more effective in both axial capacity (435%) and ductility (292%). Experimental design optimisation showed that, partial CFRP confinement offers better material efficiency as compared to full CFRP confinement. These findings are instrumental in developing a rationale and a design method for retrofitting existing columns with CFRP wrap.

description: In June 2019, more than a hundred plant researchers met in Cologne, Germany, for the 6th European Workshop on Plant Chromatin (EWPC). This conference brought together a highly dynamic community of researchers with the common aim to understand how chromatin organization controls gene expression, development, and plant responses to the environment. New evidence showing how epigenetic states are set, perpetuated, and inherited were presented, and novel data related to the three-dimensional organization of chromatin within the nucleus were discussed. At the level of the nucleosome, its composition by different histone variants and their specialized histone deposition complexes were addressed as well as the mechanisms involved in histone post-translational modifications and their role in gene expression. The keynote lecture on plant DNA methylation by Julie Law (SALK Institute) and the tribute session to Lars Hennig, honoring the memory of one of the founders of the EWPC who contributed to promote the plant chromatin and epigenetic field in Europe, added a very special note to this gathering. In this perspective article we summarize some of the most outstanding data and advances on plant chromatin research presented at this workshop.

description: We demonstrate magnetic field sensing using an ensemble of nitrogen-vacancy centers by recording the variation in the pump-light absorption due to the spin-polarization dependence of the total ground state population. Using a 532 nm pump laser, we measure the absorption of native nitrogen-vacancy centers in a chemical vapor deposited diamond placed in a resonant optical cavity. For a laser pump power of 0.4 W and a cavity finesse of 45, we obtain a noise floor of $\sim$ 100 nT/$\sqrt{\textrm{Hz}}$ spanning a bandwidth up to 125 Hz. We project a photon shot-noise-limited sensitivity of $\sim$ 1 pT/$\sqrt{\textrm{Hz}}$ by optimizing the nitrogen-vacancy concentration and the detection method.

description: Το σύγγραμμα αποβλέπει να παρουσιάσει μια εικόνα της λογοτεχνικής παραγωγής αλλά και της στάσης του κόσμου των γραμμάτων κατά τα δύσκολα χρόνια της δεκαετίας 1940-1950. Τι είδους τέχνη παράγεται σε εποχή κρίσης, σε εποχή ακροτήτων; Η στράτευση και ο ενθουσιασμός στον πόλεμο του 1940, η απραξία στην πρώτη φάση της Κατοχής και η λογοτεχνία της φυγής, έπειτα η αφύπνιση και η αντίσταση. Η λογοτεχνία του «Δεκέμβρη», οι κοινοί τόποι της στρατευμένης τέχνης. Τα πρώτα μεταπολεμικά έργα: διηγήματα για την Κατοχή, μυθιστορήματα για τον πόλεμο, αφηγήματα διαμόρφωσης της προσωπικότητας, λυρική πεζογραφία, ιστορικό μυθιστόρημα. Οι διαμάχες και οι λανθάνουσες συγκλίσεις των παρατάξεων. Η κορύφωση των παθών κατά τον εμφύλιο και το ζήτημα της νομιμοποίησης της τέχνης την εποχή της βίας. Η λογοτεχνία του στρατοπέδου. Η άνθιση της γυναικείας λογοτεχνίας λόγω της νέας θέσης που αποκτά η γυναίκα στην κοινωνία μέσα από τη συμμετοχή της στα κοινά.

Το σύγγραμμα εστιάζει στους κορυφαίους συγγραφείς ανεξάρτητα από τη γενιά στην οποία ανήκουν (από τον Σικελιανό έως τον Γιάννη Αγγελόγλου) και στα κορυφαία έργα (ποίηση, πεζό και δοκίμιο), ενώ ταυτόχρονα δείχνει τις τάσεις της εποχής μέσω της παρακολούθησης των καλλιτεχνικών μοτίβων που αναδύονται σε κάθε περίοδο: το «νησί»-ευτοπία στην α΄ φάση της Κατοχής, το «ταξίδι»-απελευθέρωση από τη συμβατικότητα (1944-1947), η «επιστροφή»-αναδίπλωση (1948-1950), κλπ. Επιπλέον παρουσιάζονται τα βασικά περιοδικά, τα καλλιτεχνικά ρεύματα και οι ιδεολογικές μετατοπίσεις.

description: In this study, the Vlasov-Poisson equation with or without collision term for plasma is solved by the unified gas kinetic scheme (UGKS). The Vlasov equation is a differential equation describing time evolution of the distribution function of plasma consisting of charged particles with long-range interaction. The distribution function is discretized in discrete particle velocity space. After the Vlasov equation is integrated in finite volumes of physical space, the numerical flux across a cell interface and source term for particle acceleration are computed to update the distribution function at next time step. The flux is decided by Riemann problem and variation of distribution function in discrete particle velocity space is evaluated with central difference method. A electron-ion collision model is introduced in the Vlasov equation. This finite volume method for the UGKS couples the free transport and long-range interaction between particles. The electric field induced by charged particles is controlled by the Poisson's equation. In this paper, the Poisson's equation is solved using the Green's function for two dimensional plasma system subjected to the symmetry or periodic boundary conditions. Two numerical tests of the linear Landau damping and the Gaussian beam are carried out to validate the proposed method. The linear electron plasma wave damping is simulated based on electron-ion collision operator. Compared with previous methods, it is shown that the current method is able to obtain accurate results of the Vlasov-Poisson equation with a time step much larger than the particle collision time. Highly non-equilibrium and rarefied plasma flows, such as electron flows driven by electromagnetic field, can be simulated easily.

description: We investigate the superconformal indices for the Chern-Simons-matter theories proposed for M2-branes probing the cones over N^{010}/Z_k, Q^{111}, M^{32} with N=2,3 supersymmetries and compare them with the corresponding dual gravity indices. For N^{010}, we find perfect agreements. In addition, for N^{010}/Z_k, we also find an agreement with the gravity index including the contributions from two types of D6-branes wrapping RP^3. For Q^{111}, we find that the model obtained by adding fundamental flavors to the N=6 theory has the right structure to be the correct model. For M^{32}, we find the matching with the gravity index modulo contributions from peculiar saddle points.

On the existence of solutions to the relativistic Euler equations in 2 spacetime dimensions with a vacuum boundary

description: We prove the existence of a wide class of solutions to the isentropic relativistic Euler equations in 2 spacetime dimensions with an equation of state of the form $p=Kρ^2$ that have a fluid vacuum boundary. Near the fluid vacuum boundary, the sound speed for these solutions are monotonically decreasing, approaching zero where the density vanishes. Moreover, the fluid acceleration is finite and bounded away from zero as the fluid vacuum boundary is approached. The existence results of this article also generalize in a straightforward manner to equations of state of the form $p=Kρ^\frac{γ+1}γ$ with $γ> 0$.

Edge state modulation by mean viscosity gradients

description: Motivated by the relevance of edge state solutions as mediators of transition, we use direct numerical simulations to study the effect of spatially non-uniform viscosity on their energy and stability in minimal channel flows. What we seek is a theoretical support rooted in a fully non-linear framework that explains the modified threshold for transition to turbulence in flows with temperature-dependent viscosity. Consistently over a range of subcritical Reynolds numbers, we find that decreasing viscosity away from the walls weakens the streamwise streaks and the vortical structures responsible for their regeneration. The entire self-sustained cycle of the edge state is maintained on a lower kinetic energy level with a smaller driving force, compared to a flow with constant viscosity. Increasing viscosity away from the walls has the opposite effect. In both cases, the effect is proportional to the strength of the viscosity gradient. The results presented highlight a local shift in the state space of the position of the edge state relative to the laminar attractor with the consequent modulation of its basin of attraction in the proximity of the edge state and of the surrounding manifold. The implication is that the threshold for transition is reduced for perturbations evolving in the neighbourhood of the edge state in case viscosity decreases away from the walls, and vice versa.

Depolarizing the Perceptual Magnet Effect

description: In recent years there has been a great deal of interest in demonstrations of the so-called "Perceptual-Magnet Effect" (PME). In these studies, AX-discrimination tasks purportedly reveal that discriminability of speech sounds from a single category varies with judged phonetic "goodness" of the sounds. However, one possible confound is that category membership is determined by identification of sounds in isolation, whereas, discrimination tasks include pairs of stimuli. In the first experiment of the current study, identifications and goodness judgments were obtained for vowels (/i/–/e/) presented in pairs. A substantial shift in phonetic identity was evidenced with changes in the context vowel. In a second experiment, listeners participated in an AX-discrimination task with the vowel pairs from the first experiment. Using the contextual identification functions from the first experiment, predictions of discriminability were calculated using the classic tenets of Categorical Perception. Obtained discriminability functions were well accounted for by predictions from identification. There was no additional unexplained variance that required the proposal of "perceptual magnets." These results suggest that PME may be nothing more than further demonstration that general discriminability is greater for cross-category stimulus pairs than for within-category pairs

description: Nuclear stellar clusters are a common phenomenon in spirals and in starbursts galaxies, and they may be a natural consequence of the star formation processes in the central regions of galaxies. HST UV imaging of a few Seyfert 2 galaxies have resolved nuclear starbursts in Seyfert 2 revealing stellar clusters as the main building blocks of the extended emission. However, we do not know whether stellar clusters are always associated with all types of nuclear activity. We present NUV and optical images provided by HST to find out the role that stellar clusters play in different types of AGNs (Seyferts and LLAGNs). Also with these images, we study the circumnuclear dust morphology as a probe of the circumnuclear environment of AGNs. Here we present a summary of the the first results obtained for the sample of Seyferts and LLAGN galaxies.

Dilaton dominance in the early Universe dilutes Dark Matter relic abundances

description: The role of the dilaton field and its coupling to matter may result to a dilution of Dark Matter (DM) relic densities. This is to be contrasted with quintessence scenarios in which relic densities are augmented, due to modification of the expansion rate, since Universe is not radiation dominated at DM decoupling. Dilaton field, besides this, affects relic densities through its coupling to dust which tends to decrease relic abundances. Thus two separate mechanisms compete each other resulting, in general, to a decrease of the relic density. This feature may be welcome and can rescue the situation if Direct Dark Matter experiments point towards small neutralino-nucleon cross sections, implying small neutralino annihilation rates and hence large relic densities, at least in the popular supersymmetric scenarios. In the presence of a diluting mechanism both experimental constraints can be met. The role of the dilaton for this mechanism has been studied in the context of the non-critical string theory but in this work we follow a rather general approach assuming that the dilaton dominates only at early eras long before Big Bang Nucleosynthesis.

description: We propose analytical models that allow us to investigate the performance of long range wide area network (LoRaWAN) uplink in terms of latency, collision rate, and throughput under the constraints of the regulatory duty cycling, when assuming exponential inter-arrival times. Our models take into account sub-band selection and the case of sub-band combining. Our numerical evaluations consider specifically the European ISM band, but the analysis is applicable to any coherent band. Protocol simulations are used to validate the proposed models. We find that sub-band selection and combining have a large effect on the quality of service (QoS) experienced in an LoRaWAN cell for a given load. The proposed models allow for the optimization of resource allocation within a cell given a set of QoS requirements and a traffic model.

description: The ground state phase diagram of the alternating spin-1/2 chains with anisotropic ferromagnetic coupling under the influence of a symmetry breaking transverse magnetic field is studied. We have used the exact diagonalization technique. In the limit where the antiferromagnetic coupling is dominant, we have identified two Ising-type quantum phase transitions. We have calculated two critical fields $h_{c_{1}}$ and $h_{c_{2}}$, corresponding to the transition between different magnetic phases of the system. It is found that the intermediate state ($h_{c_{1}}

description: Το παρόν βιβλίο απευθύνεται σε κάπως προχωρημένους προπτυχιακούς φοιτητές μαθηματικών και φυσικής καθώς και σε αντίστοιχους μεταπτυχιακούς φοιτητές.
Το βασικό θέμα επεξεργασίας είναι η θεωρία διαφορικών πολλαπλοτήτων και πολλαπλοτήτων Riemann.
Θα γίνεται προσπάθεια ώστε οι έννοιες να παρουσιάζονται με απλό τρόπο και με χρήση παραδειγμάτων χρήσιμων στους μαθηματικούς και στους φυσικούς.
Αρχικά θα παρουσιάζονται κάποιες βασικές έννοιες (εφαπτόμενο διάνυσμα, διανυσματικό πεδίο, διαφορική μορφή) στον Ευκλείδειο χώρο R^n, υπό μία οπτική ώστε να είναι εύκολη και φυσιολογική η γενίκευσή τους στις πολλαπλότητες που θα ακολουθήσουν. Θα αναπτύσσεται στη συνέχεια η θεωρία διαφορικών (λείων) πολλαπλοτήτων και πριν τις πολλαπλότητες Riemann θα γίνει μια αναφορά στους τανυστές (κ,λ)-τάξης.
Στη συνέχεια, θα παρουσιαστούν βασικά σημεία της θεωρίας των ομάδων Lie και θα γίνει αμέσως εφαρμογή στη γεωμετρια των ομάδων Lie (αριστερά αναλλοίωτες μετρικές, καμπυλότητα κλπ). Τέλος, ως φυσικό επακόλουθο, θα παρουσιαστούν κάποια στοιχεία της θεωρίας των ομογενών χώρων (γεωμετρία κατά Klein), δηλαδή μιας πολλαπλότητας της μορφής Μ = G/K, όπου G μια ομάδα Lie και Κ μια κλειστή υποομάδα Lie αυτής.

description: People routinely draw inferences about others’ preferences by observing their decisions. We study these inferences by characterizing a space of simple observed decisions. Previous work on attribution theory has identified several factors that predict whether a given decision provides strong evidence for an underlying preference. We identify one additional factor and show that a simple probabilistic model captures all of these factors. The model goes beyond verbal formulations of attribution theory by generating quantitative predictions about the full set of decisions that we consider. We test some of these predictions in two experiments: one with decisions involving positive effects and one with decisions involving negative effects. The second experiment confirms that inferences vary in systematic ways when positive effects are replaced by negative effects.
