description: "Warp drive" spacetimes and wormhole geometries are useful as "gedanken-experiments" that force us to confront the foundations of general relativity, and among other issues, to precisely formulate the notion of "superluminal" travel and communication. Here we will consider the basic definition and properties of warp drive spacetimes. In particular, we will discuss the violation of the energy conditions associated with these spacetimes, as well as some other interesting properties such as the appearance of horizons for the superluminal case, and the possibility of using a warp drive to create closed timelike curves. Furthermore, due to the horizon problem, an observer in a spaceship cannot create nor control on demand a warp bubble. To contour this difficulty, we discuss a metric introduced by Krasnikov, which also possesses the interesting property in that the time for a round trip, as measured by clocks at the starting point, can be made arbitrarily short.

description: No abstracts are to be cited without prior reference to the author.Nowadays the majority of Atlantic salmon populations in riversover the Kola Peninsula suffer significant pressure from thefisheries when the burden does not always corresponds to thepotential of resource. Besides, despite the fisheries on allRussian rivers being regulated (regulations specify that not lessthan 50% of spawning migrants participate in the spawning), thereare always fishermen and managers who doubt and ask the questionwhy it is not 30% or 20%. In this light it is a topical questionto elaborate a model of optimal exploitation of salmon stocks.

description: Topic models, such as latent Dirichlet allocation (LDA), can be useful tools for the statistical analysis of document collections and other discrete data. The LDA model assumes that the words of each document arise from a mixture of topics, each of which is a distribution over the vocabulary. A limitation of LDA is the inability to model topic correlation even though, for example, a document about genetics is more likely to also be about disease than X-ray astronomy. This limitation stems from the use of the Dirichlet distribution to model the variability among the topic proportions. In this paper we develop the correlated topic model (CTM), where the topic proportions exhibit correlation via the logistic normal distribution [J. Roy. Statist. Soc. Ser. B 44 (1982) 139--177]. We derive a fast variational inference algorithm for approximate posterior inference in this model, which is complicated by the fact that the logistic normal is not conjugate to the multinomial. We apply the CTM to the articles from Science published from 1990--1999, a data set that comprises 57M words. The CTM gives a better fit of the data than LDA, and we demonstrate its use as an exploratory tool of large document collections.

description: Talk given at "New Perspectives on Galactic Magnetism" conference, 11 June 2019.

Abstract:

The new generation of low-frequency (sub-GHz) radio telescopes, particularly LOFAR and MWA, have opened up the polarized sky in new and amazing ways. We now have the capability to explore low frequency polarization at high resolution, on large angular scales, and with large fields of view, all at the same time. In my talk I will review low-frequency Faraday tomography to date, and discuss how we can take advantage of the properties of polarization at low-frequencies to inform our analysis of the observations. In some cases, we can break the degeneracies that prevent us from modelling the magnetic field along the line of sight. There are several ongoing, planned, and possible surveys that will let us break open the low frequency polarized sky.

description: We characterize the interaction between a single atom or similar microscopic system and a light field via the scattering ratio. For that, we first derive the electrical field in a strongly focused Gaussian light beam, and then consider the atomic response. Following the simple scattering model, the fraction of scattered optical power for a weak coherent probe field leads to unphysical scattering ratios above 1 in the strong focusing regime. A refined model considering interference between exciting and scattered field into finite-sized detectors or optical fibers is presented, and compared to experimental extinction measurements for various focusing strengths.

description: No abstracts are to be cited without prior reference to the author.The changes in the proportion of the eel population in the Lower Eibe infested by Aguillicolacrassus were determined by examination of2685 eels during the years from 1985 through 1996.Since the period of rapid contagion from 1986 through 1988, the rate ofinfestation by these swimbladder worm has been increasing continuously. By 1996, almost 90% of the eels examined wereinfested by Anguillicola crassus. The average intensity ofinfestation per infected eel was 8 adultsand pre-adults or 16 larvae.A diagnostic feature is a clouding and thickening ofthe swim bladder wall, which results fromdamage caused by the larvae whiIe Iiving in the tissues or by the aduIts and pre-adults inhabitingthe lumen ofthe swim bladder and sucking the bIood ofthe host. Repeated new infestationsresuIt in further damage ofthe swim bladder, which finally can be reduced to a fully nonfunctionalmass oftissues. Other pathoIogical reactions ofthe tissues, such as inflammation,necroses, and scarring, can accompany this process.To classify the damage to the swim bladder caused by the parasites, five classes, designatedKL. I to 5, were established, with the higher numbers indicating greater damage to the hydrostaticorgan. Judging from the swim bladders in eels taken from the Lower Eibe, the frequency andseverity of the damage to the swim bladders have been increasing considerably since the parasitefirst appeared. During the course of the investigation, the proportion ofintact swim bIadders inKL.I sank to 6%, while the percentage of eels with their swim bladders massively damaged orincapabIe offunctioning, designated KL.4 and 5, rose to about 28%.The prognosis can be made that the eels with severely damaged or non-functional swim bladderswill fail to reach their breeding grounds. Considering the fact that anguillicolosis is spreadingthroughout Europe, it is feared that reduced recruitment will bring about a decrease in theEuropean eel population. Following the recently discovered invasion of Anguillicola crassus to North America a similardevelopement of the parasitosis as in Europe has to be feared.
Center vortices as rigid strings

description: It is shown that the action associated with center vortices in SU(2) lattice gauge theory is strongly correlated with extrinsic and internal curvatures of the vortex surface and that this correlation persists in the continuum limit. Thus a good approximation for the effective vortex action is the action of rigid strings, which can reproduce some of the observed geometric properties of center vortices. It is conjectured that rigidity may be induced by some fields localized on vortices, and a model-independent test of localization is performed. Monopoles detected in the Abelian projection are discussed as natural candidates for such two-dimensional fields.

This kind of problems can be interpreted as a stochastic control problem for an evolution system in an Hilbert space. The regularity of the solution of the adjoint equation, that is a backward stochastic equation in infinite dimension, plays a crucial role in the formulation of the maximum principle.

A stereoselective synthesis of the C16-C32 fragment of ionomycin
Creators: name: Spino, Joseph Arthur Claude
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation concerns the stereoselective synthesis of optically pure compound 196, the C₁₆-C₃₂ fragment of the polyether antibiotic ionomycin (1). Fragment 196 was synthesized by preparing and joining the two subunits 172 (C₁₆-C₂₂) and 122 (C₁₆-C₃₂). Compound 172 was synthesized by repetitive asymmetric aldol condensations of optically pure crotonyl imide 69 with aldehydes 129 and 139. The use of 69 allowed for the enantioselective construction of the two propionate units of fragment 172 having the "anti" configuration. Compound 122 was synthesized using the highly stereospecific oxidative permanganate cyclization of the 1,5-diene 93 to give racemic tetrahydrofuran 94, having the correct relative stereochemistry at the four asymmetric centres. The diene 93 was in turn prepared via the β-keto ester dianion methodology which allows for the stereospecific introduction of the isoprenoid unit. Diol 103, derived from 94 was resolved as its mono (+)- ̲O̲-acetylmandelate and was transformed into optically active fragment 122. Finally, to complete the synthesis of optically active fragment C₁₆-C₃₂ of ionomycin, compounds 172 and 122 were coupled via a Wittig reaction to afford the cis olefin 194 and the second tetrahydrofuran ring of 196 was introduced stereoselectively via an internal oxymercuration reaction.

description: We report on the structural and magnetic characterization of (110) and (001) La2/3Ca1/3MnO3 (LCMO) epitaxial thin films simultaneously grown on (110) and (001)SrTiO3 substrates, with thicknesses t varying between 8 nm and 150 nm. It is found that while the in-plane interplanar distances of the (001) films are strongly clamped to those of the substrate and the films remain strained up to well above t=100 nm, the (110) films relax much earlier. Accurate determination of the in-plane and out-of-plane interplanar distances has allowed concluding that in all cases the unit cell volume of the manganite reduces gradually when increasing thickness, approaching the bulk value. It is observed that the magnetic properties (Curie temperature and saturation magnetization) of the (110) films are significantly improved compared to those of (001) films. These observations, combined with 55Mn-nuclear magnetic resonance data and X-ray photoemission spectroscopy, signal that the depression of the magnetic properties of the more strained (001)LCMO films is not caused by an elastic deformation of the perovskite lattice but rather due to the electronic and chemical phase separation caused by the substrate-induced strain. On the contrary, the thickness dependence of the magnetic properties of the less strained (110)LCMO films are simply described by the elastic deformation of the manganite lattice. We will argue that the different behavior of (001) and (110)LCMO films is a consequence of the dissimilar electronic structure of these interfaces.

description: No abstracts are to be cited without prior reference to the author.Wild Atlantic salmon (Salmo salar) smolts from Conne River, Newfoundland, were capturedduring their downstrearn migration in May, 1995. From an estimated total ron of 62,750 smolts,5,000 (8%) were transferred over a thirteen day period to an estuarine aquaculture rearing site at RotiBay, 23 km away. Survival was monitored throughout the experiment with the greatest mortalityoccurring in July, approximately six-to-eight weeks following transfer. Overall survival of smolts toone-sea-winter salmon was 18.5%, over four times higher than the average survival of wild salmon toConne River during the past six years. Growth of smolts was monitored at monthly intervals untilNovember. 1995. with additional sampling in the spring and early summer of 1996. In general. thefood conversion ratio was poor which resulted in one-sea-winter survivors from the cage rearingexperiment being significantly smaller than wild salmon that retumed to Conne River. Survivors weresplit into two groups and released directly into the Bay d'Espoir estuarine fiord; one group wasreleased June 27-28. 1996. at a site approximately 7 km from the mouth of Conne River. The secondgroup was retained at Roti Bay and released July 23, 1996. Less than 50% of the surviving fish were •later accounted for in local Bay d'Espoir rivers. Approximately 80% returned to Conne River with20% straying to other streams. Lotek digitally encoded radio transmitter tags were used in evaluatingthe success of the experiment by tracking migration timing and subsequent distribution of cage releasedsalmon throughout the Conne River system.

description: We report on the first stereoscopic observations of polar coronal jets made by the EUVI/SECCHI imagers on board the twin STEREO spacecraft. The significantly separated viewpoints ($\sim$ 11$^\circ$) allowed us to infer the 3D dynamics and morphology of a well-defined EUV coronal jet for the first time. Triangulations of the jet's location in simultaneous image pairs led to the true 3D position and thereby its kinematics. Initially the jet ascends slowly at $\approx$10-20 $\mathrm{{km} {s}^{-1}}$ and then, after an apparent 'jump' takes place, it accelerates impulsively to velocities exceeding 300 $\mathrm{{km} {s}^{-1}}$ with accelerations exceeding the solar gravity. Helical structure is the most important geometrical feature of the jet which shows evidence of untwisting. The jet structure appears strikingly different from each of the two STEREO viewpoints: face-on in the one viewpoint and edge-on in the other. This provides conclusive evidence that the observed helical structure is real and is not resulting from possible projection effects of single viewpoint observations. The clear demonstration of twisted structure in polar jets compares favorably with synthetic images from a recent MHD simulation of jets invoking magnetic untwisting as their driving mechanism. Therefore, the latter can be considered as a viable mechanism for the initiation of polar jets.

description: We propose a generalization of the Tonks-Girardeau model that describes a coherent gas of cold two-level Bosons which interact with two external fields in a Ramsey interferometer. They also interact among themselves by contact collisions with interchange of momentum and internal state. We study the corresponding Ramsey fringes and the quantum projection noise which, essentially unaffected by the interactions, remains that for ideal Bosons. The dual system of this gas, an ideal gas of two-level Fermions coupled by the interaction with the separated fields, produces the same fringes and noise fluctuations. The cases of time-separated and spatially-separated fields are studied. For spatially separated fields the fringes may be broadened slightly by increasing the number of particles, but only for large particle numbers far from present experiments with Tonks-Girardeau gases. The uncertainty in the determination of the atomic transition frequency diminishes, essentially with the inverse root of the particle number.

description: We address the question of the Lorentz nature of the effective interquark interaction in QCD which leads to the formation of the QCD string between colour charges. In particular, we start from a manifestly vectorial fundamental interaction mediated by gluons and demonstrate that, as soon as chiral symmetry is broken spontaneously, the effective interquark interaction acquires a selfconsistently generated scalar part which is eventually responsible for the formation of the QCD string. We demonstrate this explicitly for a heavy-light quarkonium, using the approach of the Schwinger-Dyson-type equation and the quantum-mechanical Hamiltonian method of the QCD string with quarks at the ends.

description: We present the first results on scalar glueballs in cold, dense matter using lattice simulations of two color QCD. The simulations are carried out on a $6^3 \times 12$ lattice and use a standard hybrid molecular dynamics algorithm for staggered fermions for two values of quark mass. The glueball correlators are evaluated via a multi-step smearing procedure. The amplitude of the glueball correlator peaks in correspondence with the zero temperature chiral transition, $μ_c = m_π/2$, and the propagators change in a significant way in the superfluid phase, while the Polyakov loop is mearly insensitive to the transition. Standard analysis suggest that lowest mass in the $0^{++}$ gluonic channel decreases in the superfluid phase, but these observations need to be confirmed on larger and more elongated lattices These results indicate that a nonzero density induces nontrivial modifications of the gluonic medium.

On compressive radial tidal forces

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Radial tidal forces can be compressive instead of disruptive, a possibility that is frequently overlooked in high level physics courses. For example, radial tidal compression can emerge in extended stellar systems containing a smaller stellar cluster. For particular conditions the tidal field produced by this extended mass distribution can exert on the cluster it contains compressive effects instead of the common disruptive forces. This interesting aspect of gravity can be derived from standard relations given in many textbooks and introductory courses in astronomy and can serve as an opportunity to look closer at some aspects of gravitational physics, stellar dynamics, and differential geometry. The existence of compressive tides at the center of huge stellar systems might suggest new evolutionary scenarios for the formation of stars and primordial galactic formation processes.

Using the field of norms functor of Fontaine and Wintenberger, we show that the special fiber of a Galois cover is determined by arithmetic and geometric properties of the generic fiber and its characteristic zero specializations. As applications, we derive a criterion for good reduction in the abelian case, and give an arithmetic reformulation of the local Oort Conjecture concerning the liftability of cyclic covers of germs of curves.

The 1973-92. time series of smolt to age-2 survival rate estimates varied two orders of magnitude from <1% to 19%.Recently, survival rates declined steadily, from 9.4% in the 1989 brood to 0.1% in the 1992 brood. Estimates of age-2 survival for brood year 1993, remained low at 1.3%. Some spawning populations of WCVI chinook during the current period of poor survival consisted of about 100 females or less.

description: We analyze 5 epochs of NICER data of the black hole X-ray binary MAXI J1820+070 during the bright hard-to-soft state transition in its 2018 outburst with both reflection spectroscopy and Fourier-resolved timing analysis. We confirm the previous discovery of reverberation lags in the hard state, and find that the frequency range where the (soft) reverberation lag dominates decreases with the reverberation lag amplitude increasing during the transition, suggesting an increasing X-ray emitting region, possibly due to an expanding corona. By jointly fitting the lag-energy spectra in a number of broad frequency ranges with the reverberation model reltrans, we find the increase in reverberation lag is best described by an increase in the X-ray coronal height. This result, along with the finding that the corona contracts in the hard state, suggests a close relationship between spatial extent of the X-ray corona and the radio jet. We find the corona expansion (as probed by reverberation) precedes a radio flare by ~5 days, which may suggest that the hard-to-soft transition is marked by the corona expanding vertically and launching a jet knot that propagates along the jet stream at relativistic velocities.

Preparation and reactivity of heterosubstituted 1,3-Dienes
Creators: name: Stone, Charles
Publisher: name: University of British Columbia

description: The chemoselective hydrozirconation reaction of a series of 1-ene-3-yne molecules 51a-d, using the commercially available hydride reagent, Cp₂ZrCl(H) 1, provides an efficient route to the syntheses of 1,3-dienes 55a-d, substituted at the 1-position by the Cp₂ZrCl moiety. Similar chemoselectivity was observed in the hydrozirconation reaction of α, β-unsaturated nitriles, to generate the corresponding 1-azadienyl complexes 68-71. The complexes 55a-d were found to be useful general precursors in the preparation of other heterosubstituted 1,3-dienes. Thus, corresponding tin-, phosphorus-, boron-, selenium-and sulfur-heterosubstituted 1,3-dienes 77a-d, 79a-d, 87a-d, 88a-d and 89a-d were readily prepared in good to excellent yields by a stereoselective transfer reaction from zirconium. The 1-azadienyl complexes also served as useful starting materials in the preparation of selenium-and phosphorus-substituted 1-azadienes. The selenium-substituted 1,3-dienes 88a-d underwent a facile isomerization reaction when exposed to fluorescent light, and when thermolysed in the dark at 80°C in unsealed reactors. Mechanistic studies of this isomerization process suggested that an intermolecular pathway involving free radical intermediates was operable. A comparable photochemical isomerization reaction of the sulfur-substituted 1,3-dienes was also observed. When the cycloaddition reactions of 88a-b and 88d with maleic anhydride were performed in the absence of light at reson able temperatures, good yields of the expected endo-cycloadducts were obtained. However, when the same reactions were repeated in room light or at temperatures in excess of those required for formation of the endo-cycloadducts an, interesting, apparent [l,3]-shift of the phenylselenenyl moiety resulted. The results of a crossover experiment indicated that this rearrangment was intermolecular in nature. The preparation of the trialkylstannyl and phenylselenenyl 2-substituted 1,3-dienes (128 and 129) was achieved via a transmetalation reaction of the Grignard reagent 24. The Diels-Alder reactivity of 1,3-dienes 128 and 129, with a series of electron-deficient dienophiles, was successfully investigated. [Formula Omitted]

description: The $v_{2}$ and $v_{4}$ of pions, kaons and protons have been measured by PHENIX in 200 GeV Au+Au collisions up to $p_{T}$$\sim$6 GeV/c and 4 GeV/c, respectively. The $v_{4}$ of all these identified particles have been found to scale with the number of constituent quarks and all these particles have a similar $v_{4}$/$v_{2}^{2}$ ratio which is close to 0.9. The scaling behavior of $v_2$ is studied at high-$p_{T}$ and a deviations from the universal scaling is observed for transverse kinetic energy ($K_{ET}/nq$) higher than 1 GeV.

description: We present $Λ$CDM $N$-body cosmological simulations in the framework of a static general scalar-tensor theory of gravity. Due to the influence of the non-minimally coupled scalar field, the gravitational potential is modified by a Yukawa type term, yielding a new structure formation dynamics. We present some preliminary results and, in particular, we compute the density and velocity profiles of the most massive group.

Influence of irradiation-driven winds on the evolution of intermediate-mass black hole X-ray binaries

description: In young dense clusters, an intermediate-mass black hole (IMBH) may get a companion star via exchange encounters or tidal capture, and then evolves toward IMBH X-ray binary by the Roche lobe overflow. It is generally thought that IMBH X-ray binaries are potential ultra-luminous X-ray sources (ULXs), hence their evolution is very significant. However, the irradiation-driven winds by the strong X-ray flux from the accretion disks around the IMBHs play an important role in determining the evolution of IMBH X-ray binaries, and should be considered in the detailed binary evolution simulation. Employing the models with the MESA code, we focus on the influence of irradiation-driven winds on the evolution of IMBH X-ray binaries. Our simulations indicate that a high wind-driving efficiency ($f=0.01$ for $Z=0.02$, and $f=0.002$ for $Z=0.001$) substantially shorten the duration in the ULX stage of IMBH X-ray binaries with an intermediate-mass ($5~M_{\odot}$) donor star. However, this effect can be ignored for high-mass ($10~M_{\odot}$) donor stars. The irradiation effect ($f=0.01$ or $0.002$) markedly shrink the initial parameter space of IMBH binaries evolving toward ULXs with high luminosity ($L_{\rm X}>10^{40}~\rm erg\,s^{-1}$) and hyperluminous X-ray sources in the donor-star mass versus orbital period diagram. Furthermore, the irradiation effect results in an efficient angular momentum loss, yielding to IMBH X-ray binaries with relatively close orbits. In our simulated parameter space, about 1\% of IMBH binaries would evolve toward compact X-ray sources owing to short initial orbital periods, some of which might be detected as low-frequency gravitational wave sources.

Misspecification and Expectations Correction in New
Keynesian DSGE Models
Creators: name: Angelini, Giovanni
name: Fanelli, Luca
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2015
Subjects: SECS-P/05 Econometria

description: Abstract: This paper focuses on the dynamic misspecification that characterizes the class
of small-scale New-Keynesian models and provides a `natural' remedy for the typical difficulties
these models have in accounting for the rich contemporaneous and dynamic correlation structure
of the data, generally faced with ad hoc shock specifications. We suggest using the `best fitting'
statistical model for the data as a device through which it is possible to adapt the econometric
specification of the New-Keynesian model. The statistical model may feature an autocorrelation
structure that is more involved than the autocorrelation structure implied by the structural
model's reduced form solution under rational expectations, and it is treated as the actual agents'
expectations generating mechanism. A pseudo-structural form is built from the baseline system
of Euler equations by forcing the state vector of the system to have the same dimension as the
state vector characterizing the statistical model. We provide an empirical illustration based on
U.S. quarterly data and a small-scale monetary New Keynesian model.

description: Model patchy particles have been shown to be able to form a wide variety of structures, including symmetric clusters, complex crystals and even two-dimensional quasicrystals. Here, we investigate whether we can design patchy particles that form three-dimensional quasicrystals, in particular targeting a quasicrystal with dodecagonal symmetry that is made up of stacks of two-dimensional quasicrystalline layers. We obtain two designs that are able to form such a dodecagonal quasicrystal in annealing simulations. The first is a one-component system of 7-patch particles but with wide patches that allow them to adopt both 7- and 8-coordinated environments. The second is a ternary system that contains a mixture of 7- and 8-patch particles, and is likely to be more realizable in experiments, for example, using DNA origami. One interesting feature of the first system is that the resulting quasicrystals very often contain a screw dislocation.

Variable Cosmological Constant model: the reconstruction equations and constraints from current observational data
Creators: name: Ma, Yin-Zhe
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this paper we first give a brief review of the variable cosmological constant model and its scalar field description. We mainly discuss two types of variable cosmological constant models: $a$ power law and $H$ power law models. A method to obtain all of the equivalent scalar field potentials and the effective equation of state of the two models is presented. In addition, the dynamics of such scalar field potentials and effective equation of state are discussed in detail. The parameters of the two models are constrained by current 307 high-quality "Union" SN Ia data set, baryon acoustic oscillation (BAO) measurement from the Sloan Digital Sky Survey (SDSS), 9 observational \textrm{H(z)} data derived from the Gemini Deep Deep Survey (GDDS) and the shift parameter of the cosmic microwave background (CMB) given by the three-year Wilkinson Microwave Anisotropy Probe (\textrm{WMAP}) observations. We also calculate and draw the picture of the Hubble parameter, the deceleration parameter and the matter density of the two models. Then, we show that the indices $m$ and $n$ in the two models have specific meaning in determining properties of the models. Moreover, The reasons that indices $m$ and $n$ may also influence the behavior of effective equation of state and scalar field potentials are presented.
