Time-evolution of ionization and heating around first stars and miniquasars

description: A one dimensional radiative transfer code is developed to track the ionization and heating pattern around the first miniquasars and Population III stars. The code follows the evolution of the ionization of the species of hydrogen and helium and the intergalactic medium temperature profiles as a function of redshift. The radiative transfer calculations show that the ionization signature of the first miniquasars and stars is very similar yet the heating pattern around the two is very different. Furthermore, the first massive miniquasars (~>10^5 M_{sun}) do produce large ionized bubbles around them, which can potentially be imaged directly using future radio telescopes. It is also shown that the ionized bubbles not only stay ionized for considerable time after the switching off of the source, but continue to expand for a short while due to secondary collisions prompted by the X-ray part of their spectra. Varying spectral shapes also produced sizable variations in ionized fraction and temperature profile. We also compare the radiative transfer results with the analytical approximation usually adopted for heating by miniquasars and find that, because of the inadequate treatment of the He species, the analytical approach leads to an underestimation of the temperature in the outer radii by a factor ~5. Population III stars - with masses in the range of 10 - 1000 M_{sun} and modelled as blackbodies at a temperature of 50000 K - are found to be efficient in ionizing their surroundings. Observational effects on the 21 cm brightness temperature, the thermal and kinetic Sunyaev-Ze'ldovich effects, are also studied in the context of the upcoming radio and microwave telescopes like LOFAR and SPT.

description: The hot and dense medium produced in relativistic heavy-ion collisions has been conjectured to be accompanied by an axial charge asymmetry that may lead to a separation of electric charges in the direction of the extremely strong magnetic field, also known as the Chiral Magnetic Effect (CME). The measurement of azimuthal correlator ($Δγ$) with respect to the spectator plane, gives us an opportunity to measure the possible CME fraction beyond the flow background. Preliminary results using this approach with combined Au+Au collisions at $\sqrt{s_{NN}} =$ 200 GeV and U+U at $\sqrt{s_{NN}} =$ 193 GeV show $f_{CME}$ at $(8\pm4\pm8)$ $\%$. Meanwhile, the observability of CME has been conjectured to be dependent on $\sqrt{s_{NN}}$ due to changes in the lifetime of the magnetic field, the strengths of CME signal and non-CME background. At lower energies, the Event Plane Detector (EPD) installed in the year 2018 provides a unique capability for CME search. The background scenario test at Au+Au $\sqrt{s_{NN}} =$ 27 GeV by using $Δγ$ with respect to TPC and the new installed EPD shows a consistency with no-CME scenario in the current statistics. The method of the ongoing isobar blind analysis, and the latest sensitivity check with the event-by-event AVFD model on the different observables between Ru+Ru and Zr+Zr are also briefly discussed.

description: We review some of the most striking properties of the phase diagrams of higher dimensional black holes in pure gravity. We focus on static black hole solutions with Kaluza-Klein asymptotics and stationary black hole solutions in flat Minkowski space. Both cases exhibit a rich pattern of interconnected phases and merger points with topology changing transitions. In the first case, the phase diagram includes uniform and non-uniform black strings, localized black holes and sequences of Kaluza-Klein bubbles. In the latter case, it includes Myers-Perry black holes, black rings, black saturns and pinched black holes.

Subjects: Teaching/Communication/Extension/Profession

description: The agricultural policy of the northernmost country of Yugoslavia, the Republic of Slovenia, faces characteristic agricultural problems: a small average farm holding, high average age of farmers and a low formal level of education. The society owned, so called social sector had significant priorities in the development of Slovenian agriculture till now. With the recent political and economic changes in Eastern Europe, in the Republic of Slovenia the management conditions of the social agricultural sector and the private sector became equal. The main objective of the new Slovenian Government is to support the changes which will encourage initiatives by individuals in the private agricultural enterprises. The new organisation of Agricultural Extension Service in Republic Slovenia is described. The study of reorganisation has been done and reorganisation of former Agricultural Extension Service in Co-operatives into the Public Agricultural Extension Service in Regional Extension Units is described.

description: The gas needed to sustain star formation in galaxies is supplied by the circumgalactic medium (CGM), which in turn is affected by accretion from large scales. In a series of two papers, we examine the interplay between a galaxy's ambient CGM and central star formation within the context of the large-scale environment. We use the IllustrisTNG-100 simulation to show that the influence exerted by the large-scale galaxy environment on the CGM gas angular momentum results in either enhanced (Paper I) or suppressed (Paper II, this paper) star formation inside a galaxy. We find that for present-day quenched galaxies, both the large-scale environments and the ambient CGM have always had higher angular momenta throughout their evolutionary history since at least $z=2$, in comparison to those around present-day star-forming disk galaxies, resulting in less efficient gas inflow into the central star-forming gas reservoirs. A sufficiently high CGM angular momentum, as inherited from the larger-scale environment, is thus an important factor in keeping a galaxy quenched, once it is quenched. The process above naturally renders two key observational signatures: (1) a coherent rotation pattern existing across multiple distances from the large-scale galaxy environment, to the circumgalactic gas, to the central stellar disk; and (2) an anti-correlation between galaxy star-formation rates and orbital angular momenta of interacting galaxy pairs or groups.

description: As U.S. agriculture has changed in the 1980's, conservation has remained an important concern for farmers and land users. Recently, much emphasis has been placed on the adverse effects of some agricultural practices to the environment. This paper presents a study that will evaluate the effects of adopting resource conservation and management practices on the farmers' well-being. The study presents a recently developed linear programming technique, recursive strategic linear programming (RSLP), for an ex post analysis of case farms that have incorporated refined or alternative conservation and management practices into their whole- farm operations.

description: The TOPGöt project studies a sample of 86 high-mass star-forming regions in different evolutionary stages from starless cores to ultra compact HII regions. The aim of the survey is to analyze different molecular species in a statistically significant sample to study the chemical evolution in high-mass star-forming regions, and identify chemical tracers of the different phases. The sources have been observed with the IRAM 30m telescope in different spectral windows at 1, 2, and 3 mm. In this first paper, we present the sample and analyze the spectral energy distributions (SEDs) of the TOPGöt sources to derive physical parameters. We use the MADCUBA software to analyze the emission of methyl cyanide (CH$_3$CN), a well-known tracer of high-mass star formation. The emission of the $\rm{CH_3CN(5_{K}-4_{K})}$ K-transitions has been detected towards 73 sources (85% of the sample), with 12 non-detections and one source not observed in the frequency range of $\rm{CH_3CN(5_{K}-4_{K})}$. The emission of CH$_3$CN has been detected towards all evolutionary stages, with the mean abundances showing a clear increase of an order of magnitude from high-mass starless-cores to later evolutionary stages. We found a conservative abundance upper limit for high-mass starless cores of $X_{\rm CH_3CN}<4.0\times10^{-11}$, and a range in abundance of $4.0\times10^{-11}

description: The recently introduced hierarchical regular networks HN3 and HN4 are analyzed in detail. We use renormalization group arguments to show that HN3, a 3-regular planar graph, has a diameter growing as \sqrt{N} with the system size, and random walks on HN3 exhibit super-diffusion with an anomalous exponent d_w = 2 - \log_2ϕ= 1.306..., where ϕ= (\sqrt{5} + 1)/2 = 1.618... is the "golden ratio." In contrast, HN4, a non-planar 4-regular graph, has a diameter that grows slower than any power of N, yet, fast than any power of \ln N . In an annealed approximation we can show that diffusive transport on HN4 occurs ballistically (d_w = 1). Walkers on both graphs possess a first- return probability with a power law tail characterized by an exponent μ= 2 -1/d_w . It is shown explicitly that recurrence properties on HN3 depend on the starting site.

description: AT2019wey is a transient discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey in December of 2019. Follow-up optical, radio, and X-ray observations led to classification of this source as a Galactic black hole X-ray binary. We carried out one-epoch 6.7 GHz European VLBI (Very Long Baseline Interferometry) Network (EVN) and two-epoch multiple-frequency (1.6, 4.5, 6.7 GHz) Very Long Baseline Array (VLBA) observations within a year after its discovery. These observations reveal a fading and flat-spectrum radio source with no discernible motion. These features suggest the detection of a compact jet. The source appears resolved at milliarcsecond scales, and the source angular size versus frequency trend is consistent with scatter broadening. This allows us to constrain the lower limit of the source distance to 6 kpc, if the scattering medium is in a Galactic spiral arm. For a source location larger than 3 kpc, the estimated upper limit of the peculiar velocity, relative to the local standard of rest, suggests the asymmetric natal kick may have occurred during the black hole formation stage.

description: Using numerical and analytical methods implemented for different models we conduct a systematic study of thermodynamic properties of pairing correlation in mesoscopic nuclear systems. Various quantities are calculated and analyzed using the exact solution of pairing. An in-depth comparison of canonical, grand canonical, and microcanonical ensemble is conducted. The nature of the pairing phase transition in a small system is of a particular interest. We discuss the onset of discontinuity in the thermodynamic variables, fluctuations, and evolution of zeros of the canonical and grand canonical partition functions in the complex plane. The behavior of the Invariant Correlational Entropy is also studied in the transitional region of interest. The change in the character of the phase transition due to the presence of magnetic field is discussed along with studies of superconducting thermodynamics.

description: The spectral energy distribution (SED) in the millimetre (mm) to centimetre (cm) range is a useful tool for characterising the dust in protostellar envelopes as well as free-free emission from the protostar and outflow. While many studies have been carried out towards low- and high-mass protostars, little exists so far about solar-type protostars in high-mass star-forming regions, which are likely to be representatives of the conditions where the Solar System was born. We focus here on the OMC-2/3 solar-type protostars, which are bounded by nearby HII regions and which are, therefore, potentially affected by the high-UV illumination. We aim to understand whether the small-scale structure ($\leq$1000 au) and the evolutionary status of these solar-type protostars are affected by the nearby HII regions, as is the case for the large-scale ($\leq$10$^4$ au) gas chemical composition. We used ALMA in the 1.3 mm band (246.2 GHz) to image the continuum of 16 OMC-2/3 solar-type protostars, with an angular resolution of 0.25$''$ (100 au). We completed our data with archival data from the VANDAM survey of Orion Protostars at 333 and 32.9 GHz, respectively, to construct the dust SED, extract several dust parameters and to assess whether free-free emission is contaminating their dust SED in the cm range. From the mm to cm range dust SED, we found low dust emissivity spectral indexes ($β< 1$) for the majority of our source sample and free-free emission towards only 5 of the 16 sample sources. We were also able to confirm or correct the evolutionary status of the source sample. Finally, we did not find any dependence of the source dust parameters on their location in the OMC-2/3 filament. Our results show that the small-scale dust properties of the OMC-2/3 protostars are not affected by the high- UV illumination from the nearby HII regions.

description: We present a new path description for the states of the non-unitary M(k+1,2k+3) models. This description differs from the one induced by the Forrester-Baxter solution, in terms of configuration sums, of their restricted-solid-on-solid model. The proposed path representation is actually very similar to the one underlying the unitary minimal models M(k+1,k+2), with an analogous Fermi-gas interpretation. This interpretation leads to fermionic expressions for the finitized M(k+1,2k+3) characters, whose infinite-length limit represent new fermionic characters for the irreducible modules. The M(k+1,2k+3) models are also shown to be related to the Z_k graded parafermions via a (q to 1/q) duality transformation.

description: This paper outlines the evolution of recent agricultural policy in New Zealand, emphasizing the nature and magnitudes of assistance and economic and financial performance in the 1970s and 1980s. Changes in financial conditions which have affected farmers and altered the productivity and efficiency of the agricultural sector are described. Financial stress which has risen appreciably on New Zealand sheep and beef farms in the post deregulation period since 1984 is examined. This shows the predominant influence of debt on farm household stress, as costs of servicing debt encroach on household expenditures when net farm income falls.

Subjects: Risk and Uncertainty

description: The environment which is currently being faced by farmers in New Zealand is much more risky than it was a decade ago, and the relative importance of different sources of risk has changed over the period. It is likely that a variety of risk management strategies are being adopted in response to these changes. In this paper, some basic ideas on risk are outlined. The risk environment of New Zealand farming is outlined, definitions of risk are explored, and the different sources of risk are discussed. The idea that there is a maximum level of risk which can be tolerated is considered, and the implications of this for risk adjustments by farmers is outlined. A range of risk management strategies are discussed, and the linkage between sources of risk and responses to risk is considered. On the basis of this discussion, some concluding comments are made on the attributes of farmers who are likely to be successful managers of risk.

Then these thermalized islands will evolve with the standard cosmology. We show that such islands may be consistent with our observable universe, while has some distinctly observable signals, which may be tested in coming observations.

Subjects: Livestock Production/Industries

description: Rusa deer (Cervus timorensis rusa) were introduced into New Caledonia in 1870 where they have thrived because there were no predators. They have traditionally been hunted in the bush (30,000 animals killed annually from the total wild deer population estimated at 150,000). Venison has been considered as the main source of protein for the local inhabitants, tribes and farmers. For farmers, deer is a noxious animal because of its action on improved pastures. The sale of feral meat on the local market is prohibited.
In 1987 the local government set up deer farming pilot schemes to introduce a new economic rural activity. The meat from these farms was first prepared for the export. It is considered now that a part of this controlled production can be sold on the local market.

On the localized phase of a copolymer in an emulsion: supercritical percolation regime

description: In this paper we study a two-dimensional directed self-avoiding walk model of a random copolymer in a random emulsion. The copolymer is a random concatenation of monomers of two types, $A$ and $B$, each occurring with density 1/2. The emulsion is a random mixture of liquids of two types, $A$ and $B$, organised in large square blocks occurring with density $p$ and $1-p$, respectively, where $p \in (0,1)$. The copolymer in the emulsion has an energy that is minus $α$ times the number of $AA$-matches minus $β$ times the number of $BB$-matches, where without loss of generality the interaction parameters can be taken from the cone $\{(α,β)\in\R^2\colon α\geq |β|\}$. To make the model mathematically tractable, we assume that the copolymer is directed and can only enter and exit a pair of neighbouring blocks at diagonally opposite corners. In \cite{dHW06}, it was found that in the supercritical percolation regime $p \geq p_c$, with $p_c$ the critical probability for directed bond percolation on the square lattice, the free energy has a phase transition along a curve in the cone that is independent of $p$. At this critical curve, there is a transition from a phase where the copolymer is fully delocalized into the $A$-blocks to a phase where it is partially localized near the $AB$-interface. In the present paper we prove three theorems that complete the analysis of the phase diagram : (1) the critical curve is strictly increasing; (2) the phase transition is second order; (3) the free energy is infinitely differentiable throughout the partially localized phase.

Quantifying Variability of YSOs in the Mid-IR Over Six Years with NEOWISE

description: Variability in young stellar objects (YSOs) can be caused by various time-dependent phenomena associated with star formation, including accretion rates, geometric changes in the circumstellar disks, stochastic hydromagnetic interactions between stellar surfaces and inner disk edges, reconnections within the stellar magnetosphere, and hot/cold spots on stellar surfaces. We uncover and characterize $\sim$1700 variables from a sample of $\sim$5400 YSOs in nearby low-mass star-forming regions using mid-IR light curves obtained from the 6.5-years NEOWISE All Sky Survey. The mid-IR variability traces a wide range of dynamical, physical, and geometrical phenomenon. We classify six types of YSO mid-IR variability based on their light curves: secular variability ($Linear, Curved, Periodic$) and stochastic variability ($Burst, Drop, Irregular$). YSOs in earlier evolutionary stages have higher fractions of variables and higher amplitudes for the variability, with the recurrence timescale of FUor-type outbursts (defined here as $Δ$W1 or $Δ$W2 $>1$ mag followed by inspection of candidates) of $\sim$1000 years in the early embedded protostellar phase. Known eruptive young stars and subluminous objects show fractions of variables similar to the fraction ($\sim55\%$) found in typical protostars, suggesting that these two distinct types are not distinct in variability over the 6.5-year timescale. Along with brightness variability, we also find a diverse range of secular color variations, which can be attributed to a competitive interplay between the variable accretion luminosity of the central source and the variable extinction by material associated with the accretion process.

description: Recently the occurrence probabilities of ground- and metastable states of three-dimensional Yukawa clusters with 27 and 31 particles have been analyzed in dusty plasma experiments [Block et al., Physics of Plasmas 15, 040701 (2008)]. There it was found that, in many cases, the ground state appeared substantially less frequently than excited states. Here we analyze this question theoretically by means of molecular dynamics (MD) and Monte Carlo simulations and an analytical method based on the canonical partition function. We confirm that metastable states can occur with a significantly higher probability than the ground state. The results strongly depend on the screening parameter of the Yukawa interaction and the damping coefficient used in the MD simulations. The analytical method allows one to gain insight into the mechanisms being responsible for the occurrence probabilities of metastable states in strongly correlated finite systems.

description: This essay focuses on the relationship between tragedy and history in Romeo Castellucci’s Tragedia Endogonidia, through its treatment of the figure of Benito Mussolini (R. #07 ROMA). This Episode establishes a connection with the Eternal City by rewriting the Lateran Treaty, comparing the Church to an exoskeleton liturgically defined by gestures voided of their sense. Transplanting the celebration of the Eucharist into the world of basketball sets the Corpus Mysticum within a space intended for games. The same sort of movement arises between Panels 78 and 79 of Aby Warburg’s Bilderatlas Mnemosyne, where – with an explicit reference to the Lateran Treaty – we see the Church surrender its secular power in exchange for maintaining its symbolic power, manifested in the passage from a ritualized sacrifice to its sublimation in a formal paradigm that consists in a monstrance of the body of the athlete. The embodied figure of Mussolini reappears onstage through an intentional mystification of the “body of the Leader”. This activates a representational subversion that draws on the embodiment of the leader’s charisma – an all-pervasive ideological metaphor during Fascism – and proposes a figure that is no more than an empty icon of History, an object for (ideological) use. The image of Mussolini onstage makes both this masculine, athletic body, and along with it the exaggerated (vocal) theatricality exhibited in his oratory, dysfunctional.

description: In this work we study different notions of ranks and approximation of tensors. We consider the tensor rank, the nuclear rank and we introduce the notion of symmetric decomposable rank, a notion of rank defined only on symmetric tensors. We show that when approximating symmetric tensors, using the symmetric decomposable rank has some significant advantages over the tensor rank and the nuclear rank.

Thermal degradation of thiamine in bread
Creators: name: Nadeau, Louise
Publisher: name: University of British Columbia
Year: 2010

description: Thiamine is an important nutrient found in significant amounts in wheat flours. This vitamin is heat labile thus destruction occurs during bread baking. Using a kinetic approach, the effect of heat and pH on thiamine degradation in a model system were studied. In order to compare the stability of thiamine from natural (whole wheat) and synthetic (enriched white) sources, thermal destruction of thiamine in the two breads was investigated. Destruction rates of thiamine hydrochloride in phosphate buffer at pH 6.0 and temperatures between 80 and 120°C were measured. The breakdown reaction could be described by first order kinetics. An energy of activation of 34.2. kcal/mole was obtained. Destruction rates of thiamine hydrochloride in phosphate buffer at 120°C were measured for pH values between 4.0 and 7.0. The reaction rate increased as the system was made more alkaline, with greater destruction at pH 6.0 and above. Thiamine losses in an enriched white flour system baked at a nominal temperature of 246°C (475°F) for 60, 75 and 90 min were found to be 2.4, 27.9 and 29.2%, respectively. Two experiments were carried out with 450 g (1 lb) enriched white loaves baked at 221°C (430°F). Baking times were 30 min for the first experiment, and 15, 37 and 60 min for the second experiment. No appreciable thiamine destruction were found in either experiment. The main investigation was with a semi-model system of 12g bread loaves made from enriched white and whole wheat flours. Four different nominal oven temperatures of 177, 221, 246 and 288°C (350, 425, 475 and 550°F) were used with four different baking times for each run. The pH of the dough and baked bread were determined. Oven, crust and loaf center temperatures were monitored. The mass average temperature data of the bread during baking showed a changing rate of temperature rise, and because of this, it was not possible to obtain kinetic data. However, a linear relationship was obtained when the logarithm of the percent thiamine retention was plotted against time. This experiment showed a lower thiamine stability with higher oven temperature. Thiamine was less stable in whole wheat bread than in enriched white bread. This might be explained by higher pH and ash content in whole wheat bread. Thiamine losses during normal baking of whole wheat and enriched white bread were found to be in the range of 28.3 to 47.8%.

description: There exist many simple tools for jointly capturing variability and incomplete information by means of uncertainty representations. Among them are random sets, possibility distributions, probability intervals, and the more recent Ferson's p-boxes and Neumaier's clouds, both defined by pairs of possibility distributions. In the companion paper, we have extensively studied a generalized form of p-box and situated it with respect to other models . This paper focuses on the links between clouds and other representations. Generalized p-boxes are shown to be clouds with comonotonic distributions. In general, clouds cannot always be represented by random sets, in fact not even by 2-monotone (convex) capacities.

Extended geometry of Gambini-Olmedo-Pullin polymer black hole and its quasinormal spectrum

description: In this paper we systematically study a model of spherically symmetric polymer black holes recently proposed by Gambini, Olmedo, and Pullin (GOP). Within the framework of loop quantum gravity, the quantum parameters in the GOP model depend on the minimal area gap and the size of the discretization of the physical states. In this model, a spacelike transition surface takes place of the classical singularity. By means of coordinate transformations, we first extend the metric to the white hole region, and find that the geometric structure of the quantum black hole is similar to the wormhole structure, and the radius of the most quantum region is equal to the wormhole radius. In addition, we show that the energy conditions are violated not only at throat, but also at horizons and the spatial infinities. In order to show how the quantum effects affect the spacetimes, we calculate the Ricci and Kretschmann scalars at different places. It turns out that, as expected, the most quantum region is at the throat. Finally, we consider the quasinormal modes (QNMs) of massless scalar field perturbations, electromagnetic field perturbations, and axial gravitational perturbations. QNMs in the Eikonal limits are also considered. As anticipated, the spectrum of QNMs deviates from that of the classical case due to quantum effects. Interestingly, our results show that the quasinormal frequencies of the perturbations share the same qualitative tendency while setting quantum parameters with various values in this effective model, even if the potential deviations are different with different spins.
