description: Assessments of the cold-gas reservoir in galaxies are a cornerstone for understanding star-formation processes and the role of feedback and baryonic cycling in galaxy evolution. Here we exploit a sample of 392 galaxies (dubbed MAGMA, Metallicity and Gas for Mass Assembly), presented in a recent paper, to quantify molecular and atomic gas properties across a broad range in stellar mass, Mstar, from $\sim 10^7 - 10^{11}$ Msun. First, we find the metallicity ($Z$) dependence of alpha_CO to be shallower than previous estimates, with alpha_CO$\propto (Z/Z_\odot)^{-1.55}$. Second, molecular gas mass MH2 is found to be strongly correlated with Mstar and star-formation rate (SFR), enabling predictions of MH2 good to within $\sim$0.2 dex. The behavior of atomic gas mass MHI in MAGMA scaling relations suggests that it may be a third, independent variable that encapsulates information about the circumgalactic environment and gas accretion. If Mgas is considered to depend on MHI, together with Mstar and SFR, we obtain a relation that predicts Mgas to within $\sim$0.05 dex. Finally, the analysis of depletion times and the scaling of MHI/Mstar and MH2/Mstar over three different mass bins suggests that the partition of gas and the regulation of star formation through gas content depends on the mass regime. Dwarf galaxies tend to be overwhelmed by (HI) accretion, while for galaxies in the intermediate Mstar "gas-equilibrium" bin, star formation proceeds apace with gas availability. In the most massive "gas-poor, bimodality" galaxies, HI does not apparently participate in star formation, although it generally dominates in mass over H2. Our results confirm that atomic gas plays a key role in baryonic cycling, and is a fundamental ingredient for current and future star formation, especially in dwarf galaxies. (abridged for arXiv)

description: In this paper we introduce a notion of {\it generalized operad} containing as special cases various kinds of operad--like objects: ordinary, cyclic, modular, properads etc. We then construct inner cohomomorphism objects in their categories (and categories of algebras over them). We argue that they provide an approach to symmetry and moduli objects in non-commutative geometries based upon these "ring--like" structures. We give a unified axiomatic treatment of generalized operads as functors on categories of abstract labeled graphs. Finally, we extend inner cohomomorphism constructions to more general categorical contexts. This version differs from the previous ones by several local changes (including the title) and two extra references.
description: 71 pages. In this version, the definition of abstract categories of labeled graphs is corrected (part (iii)). This does not affect any proofs in the paper

description: J/Psi and eta_c above the QCD critical temperature T_c are studied in anisotropic quenched lattice QCD, considering whether the c\bar c systems above T_c are spatially compact (quasi-)bound states or scattering states. We adopt the standard Wilson gauge action and O(a)-improved Wilson quark action with renormalized anisotropy a_s/a_t =4.0 at β=6.10 on 16^3\times (14-26) lattices, which correspond to the spatial lattice volume V\equiv L^3\simeq(1.55{\rm fm})^3 and temperatures T\simeq(1.11-2.07)T_c. We investigate the c\bar c system above T_c from the temporal correlators with spatially-extended operators, where the overlap with the ground state is enhanced. To clarify whether compact charmonia survive in the deconfinement phase, we investigate spatial boundary-condition dependence of the energy of c\bar c systems above T_c. In fact, for low-lying S-wave c \bar c scattering states, it is expected that there appears a significant energy difference ΔE \equiv E{\rm (APBC)}-E{\rm (PBC)}\simeq2\sqrt{m_c^2+3π^2/L^2}-2m_c (m_c: charm quark mass) between periodic and anti-periodic boundary conditions on the finite-volume lattice. In contrast, for compact charmonia, there is no significant energy difference between periodic and anti-periodic boundary conditions. As a lattice QCD result, almost no spatial boundary-condition dependence is observed for the energy of the c\bar c system in J/Ψand η_c channels for T\simeq(1.11-2.07)T_c. This fact indicates that J/Ψand η_c would survive as spatially compact c\bar c (quasi-)bound states below 2T_c. We also investigate a $P$-wave channel at high temperature with maximally entropy method (MEM) and find no low-lying peak structure corresponding to χ_{c1} at 1.62T_c.

description: We propose a method to study the secrecy constraints in key generation problems where side information might be present at untrusted users. Our method is inspired by a recent work of Hayashi and Tan who used the Rényi divergence as the secrecy measure to study the output statistics of applying hash functions to a random sequence. By generalizing the achievability result of Hayashi and Tan to the multi-terminal case, we obtain the output statistics of applying hash functions to multiple random sequences, which turn out to be an important tool in the achievability proof of strong secrecy capacity regions of key generation problems with side information at untrusted users. To illustrate the power of our method, we derive the capacity region of the multiple private key generation problem with an untrusted helper for continuous memoryless sources under Markov conditions. The converse proof of our result follows by generalizing a result of Nitinawarat and Narayan to the case with side information at untrusted users.

description: Recent studies have revealed a number of striking dependence patterns in high frequency stock price dynamics characterizing probabilistic interrelation between two consequent price increments x (push) and y (response) as described by the bivariate probability distribution P(x,y) [1,2,3,4]. There are two properties, the market mill asymmetries of P(x,y) and predictability due to nonzero z-shaped mean conditional response, that are of special importance. Main goal of the present paper is to put together a model reproducing both the z-shaped mean conditional response and the market mill asymmetry of P(x,y) with respect to the axis y=0. We develop a probabilistic model based on a multi-component ansatz for conditional distribution P(y|x) with push-dependent weights and means describing both properties. A relationship between the market mill asymmetry and predictability is discussed. A possible connection of the model to agent-based picture is outlined.

description: We construct a nonlocal gauge invariant Lagrangian to model the electromagnetic interaction of proton. The Lagrangian includes all allowed operators with dimension up to five. We compute the two photon exchange contribution to elastic electron-proton scattering using this effective nonlocal Lagrangian. The one loop calculation in this model includes the standard box and cross box diagram with the standard on-shell form of the hadron electromagnetic vertices. Besides this we find an extra contribution which depends on an unknown constant. We use experimentally extracted form factors for our calculation. We find that the correction to the reduced cross section is slightly nonlinear as a function of the photon longitudinal polarization $ε$. The non-linearity seen is within the experimental error bars of the Rosenbluth data. The final result completely explains the difference between the form factor ratio $G_E/G_M$ extracted by Rosenbluth separation technique at SLAC and polarization transfer technique at JLAB.

description: We present results of a new feedback scheme implemented in the Munich galaxy formation model. The new scheme includes a dynamical treatment of galactic winds powered by supernovae explosions and stellar winds in a cosmological context. We find that such a scheme is a good alternative to empirically-motivated recipes for feedback in galaxy formation. Model results are in good agreement with the observed luminosity functions and stellar mass function for galaxies in the local Universe. In particular, the new scheme predicts a number density of dwarfs that is lower than in previous models. This is a consequence of a new feature of the model, that allows an estimate of the amount of mass and metals that haloes can permanently deposit into the IGM. This loss of material leads to the suppression of star formation in small haloes and therefore to the decrease in the number density of dwarf galaxies. The model is able to reproduce the observed mass-stellar metallicity and luminosity-gas metallicity relationships. This demonstrates that our scheme provides a significant improvement in the treatment of the feedback in dwarf galaxies. Despite these successes, our model does not reproduce the observed bimodality in galaxy colours and predicts a larger number of bright galaxies than observed. Finally, we investigate the efficiency of metal injection in winds and in the intergalactic medium. We find that galaxies that reside in haloes with M_vir < 10^12 M_sun/h may deposit most of their metal mass into the intergalactic medium, while groups and clusters at z=0 have lost at most a few percent of their metals before the bulk of the halo mass was accreted.

description: We compute the quasinormal spectra for scalar, Dirac and electromagnetic perturbations of the Schwarzschild-de Sitter geometry in the framework of scale-dependent gravity, which is one of the current approaches to quantum gravity. Adopting the widely used WKB semi-classical approximation, we investigate the impact on the spectrum of the angular degree, the overtone number as well as the scale-dependent parameter for fixed black hole mass and cosmological constant. We summarize our numerical results in tables, and for better visualization, we show them graphically as well. All modes are found to be stable. Our findings show that both the real part and the absolute value of the imaginary part of the frequencies increase with the parameter $ε$ that measures the deviation from the classical geometry. Therefore, in the framework of scale-dependent gravity the modes oscillate and decay faster in comparison with their classical counterparts.

In our opinion, this approach is more rich than classical self-similar ones, and more suitable for astrophysical jets we observe. In particular, it allows us describing the central (and, hence, the most energetic) part of the flow.

description: The goal of generative models is to learn the intricate relations between the data to create new simulated data, but current approaches fail in very high dimensions. When the true data generating process is based on physical processes these impose symmetries and constraints, and the generative model can be created by learning an effective description of the underlying physics, which enables scaling of the generative model to very high dimensions. In this work we propose Lagrangian Deep Learning (LDL) for this purpose, applying it to learn outputs of cosmological hydrodynamical simulations. The model uses layers of Lagrangian displacements of particles describing the observables to learn the effective physical laws. The displacements are modeled as the gradient of an effective potential, which explicitly satisfies the translational and rotational invariance. The total number of learned parameters is only of order 10, and they can be viewed as effective theory parameters. We combine N-body solver FastPM with LDL and apply them to a wide range of cosmological outputs, from the dark matter to the stellar maps, gas density and temperature. The computational cost of LDL is nearly four orders of magnitude lower than the full hydrodynamical simulations, yet it outperforms it at the same resolution. We achieve this with only of order 10 layers from the initial conditions to the final output, in contrast to typical cosmological simulations with thousands of time steps. This opens up the possibility of analyzing cosmological observations entirely within this framework, without the need for large dark-matter simulations.

description: We present the first $L-$band (2.8 to 4.1~$μ$m) spectroscopy of $κ$~Andromedae~b, a $\sim20~M_{\mathrm{Jup}}$ companion orbiting at $1^{\prime\prime}$ projected separation from its B9-type stellar host. We combine our Large Binocular Telescope ALES integral field spectrograph data with measurements from other instruments to analyze the atmosphere and physical characteristics of $κ$~And~b. We report a discrepancy of $\sim20\%$ ($2σ$) in the $L^{\prime}$ flux of $κ$~And~b when comparing to previously published values. We add an additional $L^{\prime}$ constraint using an unpublished imaging dataset collected in 2013 using LBTI/LMIRCam, the instrument in which the ALES module has been built. The LMIRCam measurement is consistent with the ALES measurement, both suggesting a fainter $L$-band scaling than previous studies. The data, assuming the flux scaling measured by ALES and LMIRCam imaging, are well fit by an L3-type brown dwarf. Atmospheric model fits to measurements spanning 0.9-4.8~$μ$m reveal some tension with the predictions of evolutionary models, but the proper choice of cloud parameters can provide some relief. In particular, models with clouds extending to very-low pressures composed of grains $\leq1~μ$m appear to be necessary. If the brighter $L^{\prime}$ photometry is accurate, there is a hint that sub-solar metallicity may be required.

description: Supernova (SN) explosions, through the metals they release, play a pivotal role in the chemical evolution of the Universe and the origin of life. Nebular phase spectroscopy constrains such metal yields, for example through forbidden line emission associated with OI, CaII, FeII, or FeIII. Fluid instabilities during the explosion produce a complex 3D ejecta structure, with considerable macroscopic, but no microscopic, mixing of elements. This structure sets a formidable challenge for detailed nonlocal thermodynamic equilibrium radiative transfer modeling, which is generally limited to 1D in grid-based codes. Here, we present a novel and simple method that allows for macroscopic mixing without any microscopic mixing, thereby capturing the essence of mixing in SN explosions. With this new technique, the macroscopically mixed ejecta is built by shuffling in mass space, or equivalently in velocity space, the shells from the unmixed coasting ejecta. The method requires no change to the radiative transfer, but necessitates high spatial resolution to resolve the rapid variation in composition with depth inherent to this shuffled-shell structure. We show results for a few radiative-transfer simulations for a Type II SN explosion from a 15Msun progenitor star. Our simulations capture the strong variations in temperature or ionization between the various shells that are rich in H, He, O, or Si. Because of nonlocal energy deposition, gamma rays permeate through an extended region of the ejecta, making the details of the shell arrangement unimportant. The greater physical consistency of the method delivers spectral properties at nebular times that are more reliable, in particular in terms of individual emission line strengths, which may serve to constrain the SN yields and, for core collapse SNe, the progenitor mass. The method works for all SN types.

description: This report delves into how frontline insights (feedback and/or views coming from frontline healthcare workers and patients) are escalated and used by national and global decision makers in public health systems and other entities to manage well established health products' markets and take market level decisions. 

In the research, several examples showed that utilizing ongoing end-user experiences with well-established health products could optimize such products' markets. It can assure continuous access to quality products and thereby deliver the associated health impact. Several opportunities to overcome the key barriers that prevent this from happening and unlock the power of frontline insights were identified and classified into those which build the salience around this topic, those which align the incentives of global health stakeholders towards appropriate goals and those which address the ability of decision makers to access and leverage frontline insights.
Vertical transmission of pathogens and of immunity in salmonids
Creators: name: Brown, Laura Louise
Publisher: name: University of British Columbia
Year: 2009

description: Bacterial kidney disease (BKD) in salmonids is caused by Renibacterium salmoninarum (Rs) which can be transmitted vertically through salmonid eggs. This study investigated various phenomena in salmonid eggs relating to the control of this salmonid pathogen. First, it was shown that exposure of coho salmon at the egg stage to Rs (and certain of its antigens) induces at least partial immunosuppression. Coho salmon eggs were injected with various Rs antigens. The eggs were fertilized and the progeny were challenged with live, virulent Rs. Fish that had been injected, as eggs, with a 57 kDa protein of Rs (p57) demonstrated a significantly higher cumulative l5ercent mirtality (50%) than the saline-injected controls (14%). A decreased proportion of phagocytic cells isolated from fish exposed, as eggs, to 100 ng p57, showed respiratory burst activity (0.4%) compared with the proportion of cells isolated from the saline-injected group (16.5 %) that showed respiratory burst activity. Second, a polymerase chain reaction (PCR) protocol to detect DNA from Rs within individual salmonid eggs was developed, the intent being to devise a detection system that would permit fish culturists to avoid the pathogen. Using two primers that were designed to amplify a 501 base-pair fragment of the gene encoding p57, the reaction was shown to be sufficiently sensitive to detect DNA from as few as two Rs cells per egg. The results indicate that the PCR is a more sensitive and specific method of screening broodstock salmonids and their eggs for Rs than the immunodiagnostic assays now routinely used. Third, it was shown that protective immunoglobulins can be passively transferred into salmonid eggs as a means of immunizing juvenile salmonids against vertically transmitted pathogens. Resistance to Vibrio anguillarum (Va) was used as the criterion of passive transfer because it is known that resistance to vibriosis is antibody-mediated. Antibodies raised against Va in rabbits and in chinook salmon were injected into female coho salmon before spawning. Based on immunoassays of egg contents, rabbit antibodies (but not salmonid antibodies) appeared to be incorporated into the eggs. Contents of eggs from all injected broodstock (including saline-injected controls) were injected into naïve coho salmon fry, which were then challenged with live Va. Egg material from broodstock injected with rabbit antiserum conferred protection against Va; in contrast, egg material from broodstock injected with chinook antibodies or saline did not. Samples of fry from the injected broodstock were also challenged with Va following absorption of their yolk sacs. Such fry from salmon injected with rabbit or chinook antibodies were not protected. Overall, the results suggest that passive vertical transfer of immunity occurs within salmonids with mammalian but not salmonid antibodies; further, the protection is not maintained for long after the yolk sac is absorbed. The significance of these results is discussed.

We examine the community structure in these networks using several methods, revealing strong links between certain committees as well as an intrinsic hierarchical structure in the House as a whole. We identify structural changes, including additional hierarchical levels and higher modularity, resulting from the 1994 election, in which the Republican party earned majority status in the House for the first time in more than forty years. We also combine our network approach with analysis of roll call votes using singular value decomposition to uncover correlations between the political and organizational structure of House committees.

The Effective Field Theory of Large-Scale Structure (EFTofLSS) provides a consistent way to predict the clustering of dark matter and baryons on large scales, where their leading corrections in perturbation theory are given by a simple and calculable functional form even after the onset of baryonic processes. In this paper, we extend the two-fluid-like system up to two-loop order in perturbation theory. Along the way, we show that a new linear counterterm proportional to the relative velocity of the fluids could generically be present, but we show that its effects are expected to be small in our universe. Regardless, we show how to consistently perform perturbation theory in the presence of this new term. We find that the EFTofLSS at two-loop order can accurately account for the details of baryonic processes on large scales. We compare our results to a hydrodynamical $N$-body simulation at many redshifts and find that the counterterms associated with the leading corrections to dark matter and baryons start to differ between redshifts $z \approx 3$ and $z \approx 2$, signaling the onset of star-formation physics. We then use these fits to compute the lensing power spectrum, show that the understanding of baryonic processes will be important for analyzing CMB-S4 data, and show that the two-loop EFTofLSS accurately captures these effects for $\ell \lesssim 2000$. Our results are also potentially of interest for current and future weak lensing surveys.

description: Lepton-flavour violating tau-decays are predicted in many extensions of the Standard Model at a rate observable at future collider experiments. In this article we focus on the decay tau to mu mu antimu, which is a promising channel to observe lepton-flavour violation at the Large Hadron Collider LHC. We present analytic expressions for the differential decay width derived from a model-independent effective Lagrangian with general four-fermion operators, and estimate the experimental acceptance for detecting the decay tau to mu mu antimu at the LHC. Specific emphasis is given to decay angular distributions and how they can be used to discriminate new physics models. We provide specific predictions for various extensions of the Standard Model, including supersymmetric, little Higgs and technicolour models.

description: Σκοπός αυτής της μεταπτυχιακής εργασίας είναι η φιλοσοφική μελέτη της Νιτσεϊκής υπερβατικής - υπερβαίνουσας ζωής, μέσω μιας πολυεπίπεδης αντανάκλασης της Τέχνης. Μιας Τέχνης η οποία εν προκειμένω ωθεί τον άνθρωπο να δει την πραγματικότητα μέσα από ένα πρίσμα εξιδανίκευσης και μεταμόρφωσης, μετατρέποντας την χαοτική κατάσταση που τον περιβάλλει σε μία αρμονική πραγματικότητα όπου υπερισχύουν ποιοτικά χαρακτηριστικά ύψιστης πνευματικής και αισθητικής στάθμης. Σ’αυτή τη φιλοσοφική διαδρομή έγινε ανάλυση σημαντικών ιδεών της νιτσεϊκής φιλοσοφίας ,όπως η ‘’ Γέννηση της Τραγωδίας’’ και της ‘’Βούλησης για Δύναμη’’ όπως επίσης και αποδόμησης του ‘’Τραγικού’’ μέσω μιας πνευματικής διάστασης με βασική έκφραση μορφές ‘’Τέχνης όπως για παράδειγμα το θέατρο , η μουσική.
description: Τhe aim of this master thesis is the philosophical study of Nietzche’s metaphysical life, through a multilevel reflection of Art. Sayihg Art, we refer to a conceprtion of Art that it triggers the person to face the reality through an ideal and transformative ‘prisma’’ that it allows him to convert the ‘’chaotic’’ situation that it surrrounds him to a reality of ‘’harmony’’ that quality ‘’points’’ of highest mental and ‘’asthetic’’ characteristics prevail.In this philosophical process there was an analysis of important ideas of Nirtzche’s philosophy, as is the ‘’Birth of Tragedy’’ and the ‘’Will to Power’’ as well as a deconsruction of the meaning of ‘’Tragic’’through a mental dimension employing basic expressions of Art, as for instance , theater, music.

description: In the present thesis, certain aspects of biology and ecology of the parasitoid Bracon brevicornis (Hymenoptera Braconidae) were determined. The experiments were carried out at the Laboratory of Applied Zoology and Parasitology of the Aristotle University of Thessaloniki, during 2007-2009. Development of immature stages, adult longevity, fecundity and sex ratio three generations of parasitoid B. brevicornis when reared on Ephestia kuehniella larvae as well as the effect of males absence on adult longevity and fecundity were studied under laboratory conditions. It was found that the mean developmental time from egg to adult stage was 13,4 days. The adult longevity and fecundity with or without presence of males were didn’t differed significantly. By contrast, the sex ratio differed significantly between generations. We also studied also, the effects of parasitoids age and hosts number on fecundity and were found that the density of four larvae and the age of ten days were betteron fecundity. The results could be useful for mass-rearing of the parasitoids.

description: Symbiotic binaries are long period interacting binaries consisting of a white dwarf (WD) accreting material from a cool evolved giant star via stellar winds. In this paper we study the symbiotic binary LIN 358 located in the SMC. We have observed LIN 358 with the integral field spectrograph WiFeS and obtained its line emission spectrum. With the help of the plasma simulation and spectral synthesis code Cloudy, we have constructed a 2D photo-ionisation model of LIN 358. From comparison with the observations, we have determined the colour temperature of the WD in LIN 358 to be 19 eV, its bolometric luminosity $L = (1.02 \pm 0.15) \times 10^{38}$ erg s$^{-1}$, and the mass-loss rate from the donor star to be $ 1.2 \times 10^{-6}$ M$_{\odot}$ yr$^{-1}$. Assuming a solar H to He ratio in the wind material, a lower limit to the accreted mass fraction in LIN 358 is 0.31. The high mass-accretion efficiency of a wind Roche lobe overflow implies that the WD is accreting above the upper boundary of stable hydrogen fusion and thus growing in mass with the maximal rate of $\approx 4 \times 10^{-7}$ M$_{\odot}$ yr$^{-1}$. This causes the WD photosphere to expand, which explains its low colour temperature. Our calculations show that the circumstellar material in LIN 358 is nearly completely ionized except for a narrow cone around the donor star, and that the WD emission is freely escaping the system. However, due to its low colour temperature, this emission can be easily attenuated by even moderate amounts of neutral ISM. We speculate that other symbiotic systems may be operating in a similar regime, thus explaining the paucity of observed systems.

description: We develop a new method to calculate eigenvalues in frustrated quantum spin models. It is based on the stochastic state selection (SSS) method, which is an unconventional Monte Carlo technique we have investigated in recent years. We observe that a kind of equilibrium is realized under some conditions when we repeatedly operate a Hamiltonian and a random choice operator, which is defined by stochastic variables in the SSS method, to a trial state. In this equilibrium, which we call the SSS equilibrium, we can evaluate the lowest eigenvalue of the Hamiltonian using the statistical average of the normalization factor of the generated state. The SSS equilibrium itself has been already observed in un-frustrated models. Our study in this paper shows that we can also see the equilibrium in frustrated models, with some restriction on values of a parameter introduced in the SSS method. As a concrete example, we employ the spin-1/2 frustrated J1-J2 Heisenberg model on the square lattice. We present numerical results on the 20-, 32-, 36-site systems, which demonstrate that statistical averages of the normalization factors reproduce the known exact eigenvalue in good precision. Finally we apply the method to the 40-site system. Then we obtain the value of the lowest energy eigenvalue with an error less than 0.2%.

description: In this paper, we investigate the role of environmental factors as potential drivers of internal migrations in Tanzania, along with a number of socio-economic factors traditionally identified as key correlates. Climate changes are expected to exert pressure on areas which mainly rely on agricultural activities and, as a result, act as push factors for population movements. Yet, understanding the association between migration, environmental conditions, and objectively-determined characteristics of origin and destination territories remains a challenging task, especially in developing countries. In this study, we follow a macro approach and focus on migration flows across Tanzanian districts. By implementing a gravity-type model, we analyse the potential impact of environmental shocks and socio-economic characteristics of both the area of origin and destination on inter-districts migration.
