Loop quantum cosmology and inhomogeneities

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Inhomogeneities are introduced in loop quantum cosmology using regular lattice states, with a kinematical arena similar to that in homogeneous models considered earlier. The framework is intended to encapsulate crucial features of background independent quantizations in a setting accessible to explicit calculations of perturbations on a cosmological background. It is used here only for qualitative insights but can be extended with further more detailed input. One can thus see how several parameters occuring in homogeneous models appear from an inhomogeneous point of view. Their physical roles in several cases then become much clearer, often making previously unnatural choices of values look more natural by providing alternative physical roles. This also illustrates general properties of symmetry reduction at the quantum level and the roles played by inhomogeneities. Moreover, the constructions suggest a picture for gravitons and other metric modes as collective excitations in a discrete theory, and lead to the possibility of quantum gravity corrections in large universes.

description: Baryon production is studied within the framework of quantized fragmentation of QCD string. Baryons appear in the model in a fairly intuitive way, with help of causally connected string breakups. A simple helical approximation of QCD flux tube with parameters constrained by mass spectrum of light mesons is sufficient to reproduce masses of light baryons.

description: In a previous study (Comp. Phys. Com.(2005) Vol.169, 139-143), we clarified the dependence of the phase structure on the hydrophilicity of an amphiphilic molecule by varying the interaction potential between the hydrophilic molecule and water(aAA) in a dissipative particle dynamics (DPD) simulation using the Jury model. In the present paper, we perform another DPD simulation using the previous model to investigate the dependence of the interaction potential between adjacent hydrophilic groups on the phase structure. By varying the coefficient of the interaction potential between adjacent hydrophilic groups aAA (aAA=15,25,40, and 250) at a dimensionless temperature of T=0.5 and a concentration of amphiphilic molecules in water of phi=50%, hexagonal (aAA=14,25,40) and micellar (aAA=250) phases were observed. In comparison with the previous results, the dependence of the A-B dimer's shape on aAA was determined to be weaker than that on aAA. Therefore, it is concluded that the solvent water W plays an important role in aggregation of the A-B dimers.

Strobed Imaging as a Method for the Determination and Diagnosis of Local Seeing
Creators: name: Stubbs, Christopher W.
Publisher: name: arXiv
Year: 2021
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: The image quality budget of many telescopes can have substantial contributions from local seeing, both``mirror'' and ``dome'', which arise from turbulence and temperature variations that are difficult to quantify, measure directly, and ameliorate. We describe a method to determine the ``local'' seeing degradation due to wavefront perturbations within the final tens of meters of the optical path from celestial sources to a ground-based telescope, using the primary instrument and along the same path taken by light from celestial sources. The concept involves placing strobed emitters along the light path to produce images on the main focal plane that ``freeze'' different realizations of index perturbations. This method has the advantage of measuring directly the image motion and scintillation imparted by the dynamic spatial and temporal structure of local perturbations in the index of refraction along the light path, with a clean separation from seeing induced in the atmosphere above the dome. The strobed-source approach allows for rapid image motion and scintillation to be measured directly on the focal plane, even for large-aperture telescopes with wide field instruments and slow shutters, such as that being constructed for the Rubin Observatory. A conceptual design is presented that uses the ``guider'' CCDs in the Rubin telescope focal plane to make local-seeing measurements on demand, perhaps even during science exposures.

description: General approach for consideration of primary ferroic (ferroelectric, ferromagnetic, ferroelastic) nanoparticles phase transitions was proposed in phenomenological theory framework. The surface stress, order parameter gradient, striction as well as depolarization and demagnetization effects were included into the free energy. The strong intrinsic surface stress under the curved nanoparticle surface was shown to play the important role in the shift of transition temperature (if any) up to the appearance of new ordered phase absent in the bulk ferroic. The approximate analytical expression for the size-induced ferroelectric transition temperature dependence on cylindrical or spherical nanoparticle sizes, polarization gradient coefficient, correlation radius, intrinsic surface stress and electrostriction coefficient was derived. It was shown that the transition temperature of nanoparticle could be higher than the one of the bulk material. The best conditions of ferroelectric properties conservation and enhancement in nanowires correspond to the radius 5-50nm and compressive surface stress. Under the favorable conditions size effects (spatial confinement) induces ferroelectric phase in incipient ferroelectrics nanowires and nanospheres. The prediction of size-induced ferroelectricity in KTaO3 nanorods with radius less then 5-20 nm at room temperatures could be important for the next step of device miniaturization based on 3D nanostructures.

Rare events of a peculiar thermonuclear supernova that precedes a core collapse supernova

Year: 2021
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We study stellar binary evolution that leads to the formation of a white dwarf (WD) that explodes in a thermonuclear supernova at the termination of a common envelope evolution (CEE) shortly before the core of its companion explodes as a core-collapse supernova (CCSN). The CCSN explosion of the core, which is the remnant of a red supergiant (RSG) star, might take place few months to several years after the explosion of the WD as a thermonuclear supernova, i.e., a type Ia peculiar supernova (peculiar SN Ia). Using the evolutionary code MESA-binary we simulate evolution of binary systems with stars of initial masses of 6-7.5Mo. The more massive star, the primary, transfers mass to the secondary star and leaves a CO WD remnant. The secondary becomes massive enough to end in a CCSN. As the secondary evolves to the RSG phase it engulfs the WD and the system experience a CEE that ends with a WD-core binary system at an orbital separation of a_f ~ 1-5Ro. Our simulations show that the core explodes as a CCSN at t_{CEE-CCSN} ~ 3000 - 10^5 yr after the CEE. We assume that if the WD accretes helium-rich gas from the core it might explode as a SN Ia in the frame of the double detonation scenario for SNe Ia and peculiar SNe Ia. We predict the very rare occurrence of a peculiar SN Ia followed within months to years by a CCSN.

How to find horizon-independent optimal strategies leading off to infinity: a max-plus approach

description: A general problem in optimal control consists of finding a terminal reward that makes the value function independent of the horizon. Such a terminal reward can be interpreted as a max-plus eigenvector of the associated Lax-Oleinik semigroup. We give a representation formula for all these eigenvectors, which applies to optimal control problems in which the state space is non compact. This representation involves an abstract boundary of the state space, which extends the boundary of metric spaces defined in terms of Busemann functions (the horoboundary). Extremal generators of the eigenspace correspond to certain boundary points, which are the limit of almost-geodesics. We illustrate our results in the case of a linear quadratic problem.

Essays on investor-manager conflict and corporate financial decision-making
Creators: name: Zhang, Guochang
Publisher: name: University of British Columbia
Year: 2008

description: This thesis examines the role of financial policy in resolving investment conflicts between investors and managers. The method of analysis is an analytical one. The thesis first surveys two areas of research: agency-theoretical studies of corporate capital investment and capital structure theories. The main body of the thesis consists of three essays in which various capital budgeting situations are modelled and different aspects of corporate financial policy are analysed. Essay one models an investment problem of a multiple division firm and shows that capital rationing can be used to force managers to compete for investment capital and therefore reduce their incentive to shirk. The main result is that, if a firm’s investment opportunities are not highly profitable, investors may be better off with capital rationing even though rationing forces the firm to forgo some profitable projects. Essay two demonstrates that direct compensation may be ineffective in providing proper managerial incentives in the presence of the limited liability condition but managerial stock acquisition can be useful instead. The signalling and screening forms of contracting for stock acquisition are analysed and then compared. The analysis provides an explanation for the existence of insider stock ownership. Essay three considers situations where external monitoring is required to discipline managers. The need for monitoring changes the structure of corporate ownership and alters the nature of agency conflict. Within this context, debt is shown to be useful in improving firms’ investment efficiency because of its risk-shifting effect. Implications and empirical evidence are discussed at the end.

description: We present a metamaterial that acts as a strongly resonant absorber at terahertz frequencies. Our design consists of a bilayer unit cell which allows for maximization of the absorption through independent tuning of the electrical permittivity and magnetic permeability. An experimental absorptivity of 70% at 1.3 terahertz is demonstrated. We utilize only a single unit cell in the propagation direction, thus achieving an absorption coefficient $α$ = 2000 cm$^{-1}$. These metamaterials are promising candidates as absorbing elements for thermally based THz imaging, due to their relatively low volume, low density, and narrow band response.

description: Parvodinium (Peridiniopsidaceae) comprises a fairly species-rich group of relatively small peridinialean dinophytes that differ only in inconspicuous traits. No DNA sequence information is available for many of these species, although such links are important for their unambiguous identification. We examined two species of Parvodinium using light and scanning electron microscopy. Sequences of the rRNA complex (including 32 new GenBank entries) were obtained and embedded in a representative taxon sample of Peridiniopsidaceae for molecular phylogenetics. Based on DNA sequence comparison the two species are closely related and comprise the sister group to Parvodinium marciniakii. The morphologies grossly matched the descriptions of Parvodinium dzieduszyckii and Parvodinium lubieniense, respectively, to which the studied materials are tentatively assigned. Our approach of integrative taxonomy provides links between morphologies and DNA sequences, filling the gaps in reference data bases that are essential in metabarcoding studies. Species of Parvodinium are not identifiable based on a single autapomorphy but rather based on a unique combination of traits. Developmental processes of both species, such as vegetative mitosis and sexual reproduction, appear similar to other species of Parvodinium, but life history of dinophytes remains understudied in general. Distinct and unique combination of traits characterise species of Parvodinium.V4 SSU sequences diagnostic for species of Parvodinium.Vegetative cell division (eleutheroschisis) outside parental theca.

Protective behavioural strategies : gender, context, and the health belief model as predictors of use
Creators: name: Irvine, NM
Publisher: name: University of Tasmania
Year: 2024

description: Protective behavioural strategies (PBS) are cognitive/social/behavioural strategies associated with reduced likelihood of alcohol-related harms. Due to different reported rates of harm in young adults who drink, this study aimed to investigate the relationship between PBS use (specifically those reducing the likelihood of interpersonal harm), gender and drinking context, namely public contexts (bars, nightclubs, etc) versus private contexts (house parties, university accommodation, etc). The study also aimed to examine the health behaviour models were associated with PBS use. 146 participants (71% female), responded to an anonymous survey. Gender and context where associated with PBS use, where females used more strategies than men, and PBS were used more in public contexts than private contexts (all p <.001). However, the gender and context interaction with PBS use was not significant (p = .08). The health belief model accounted for approximately 25% of PBS variation in both contexts and perceived susceptibility and cues to action were the strongest predictor components (all p <.001). These results provide important information regarding tendencies and motivations for drinking safety behaviours in Australian young adults. The association between PBS, susceptibility and cues in the health belief model may merit further examination for causation and potential utilisation in health campaigns.

description: Dissolving armored bubbles stabilize with nonspherical shapes by jamming the initially Brownian particles adsorbed on their interfaces. In a gas-saturated solution, these shapes are characterized by planar facets or folds for decreasing ratios of the particle to bubble radii. We perform numerical simulations that mimic dissolution, and show that the faceted shape represents a local minimum of energy during volume reduction. This minimum is marked by the vanishing of the Laplace overpressure $ΔP$, which together with the existence of a $V$-interval where $dΔP/dV>0$ guarantees stability against dissolution. The reduction of $ΔP$ is due to the saddle-shape deformation of most of the interface which accompanies the reduction in the mean curvature of the interface.

description: The subject of this postgraduate diploma thesis was the scientific study of the conservation on the roof of the "Liti" of the Catholic Temple of the Holy Monastery of Vatopedi through non-destructive spectroscopy techniques. By working as a conservator myself during the execution of the project, it was possible, in consultation with the monks, to collect representative samples from the various pigments of the object for the purpose of their further study. This particular work is attributed to the Galatsian painters who left their time in the painting of Mount Athos. The samples were studied through X-ray fluorescence spectroscopy (XRF) and Raman Spectroscopy. In addition to the spectroscopic techniques, the samples were also studied in an optical microscope. The study also mentions the conservation stages of wood-carved ceilings. During the study of the samples at the Artifact Diagnostic Center of Ormylia, measurements were made in situ on two portable icons of the Galatsian painters and their results are presented comparatively at the study. In conclusion, the study is also commented the results of color measurements made in order to observe the effect of oxidized varnishes on the colors of the artifact.

description: Supplementary Material 1: Figure S1. Phase 1/2 OLE study design and patient disposition. aPatients received givosiran or placebo once monthly (up to 4 doses) or once quarterly during a 12-week period and were followed for an additional 12 weeks after the last injection. bScreening assessment for the OLE was the last assessment performed during the Phase 1 study. If >60 days had elapsed since last Phase 1 study assessment, safety assessments (eg, ECG and clinical laboratory tests) were repeated before administering the first dose of givosiran (OLE Day 1). cGivosiran dosing: patients initially received 2.5 mg/kg once monthly, 5.0 mg/kg once monthly, or 5.0 mg/kg once every 3 months (as per Phase 1 study protocol); all patients transitioned to 2.5 mg/kg once monthly starting August 2017. dWithdrawals were due to treatment-related serious AE of anaphylactic reaction in 1 patient and decision to discontinue treatment due to lack of treatment response in 1 patient. AE, adverse event; ECG, electrocardiogram; OLE, open-label extension.

description: The coexistence of ferroelectricity and spin-orbit coupling (SOC) in noncentrosymmetric systems may allow for a nonvolatile control of spin degrees of freedom by switching the ferroelectric polarization through the well-known ferroelectric Rashba effect (FRE). Although the FER has been widely observed for bulk ferroelectric systems, its existence in two-dimensional (2D) ferroelectric systems is still very rarely discovered. Based on first-principles calculations, supplemented with $\vec{k}\cdot\vec{p}$ analysis, we report the emergence of the FRE in the Ga$XY$ ($X$= Se, Te; $Y$= Cl, Br, I) monolayer compounds, a new class of 2D materials having in-plane ferroelectricity. Due to the large in-plane ferroelectric polarization, a giant out-of-plane Rashba effect is observed in the topmost valence band, producing unidirectional out-of-plane spin textures in the momentum space. Importantly, such out-of-plane spin textures, which can host a long-lived helical spin mode known as a persistent spin helix, can be fully reversed by switching the direction of the in-plane ferroelectric polarization. Thus, our findings can open avenues for interplay between the unidirectional out-of-plane Rashba effect and the in-plane ferroelectricity in 2D materials, which is useful for efficient and non-volatile spintronic devices.

description: Quantum transport through an open periodic array of up to five dots is investigated in the presence of a magnetic field. The device spectrum exhibits clear features of the band structure of the corresponding one-dimensional artificial crystal which evolves with varying field. A significant magnetically controlled current flow is induced with changes up to many orders of magnitude depending on temperature and material parameters. Our results put forward a simple design for measuring with current technology the magnetic subband formation of quasi one-dimensional Bloch electrons.

description: In this version of the article, the error in determining the pump peak power has been corrected. The pump power was verified by integrating the Poyting vector over an area with a radius several times larger than the beam waist radius and it was determined that the peak power is 0.002 W instead of 0.008 W, which only affected the values of the nonlinear conversion coefficient shown in Fig. 3 (a-b)

Simultaneous radio-interferometric and high-energy TeV observations of the gamma-ray blazar Mkn 421

description: The TeV-emitting BL Lac object Mkn 421 was observed with very long baseline interferometry (VLBI) at three closely-spaced epochs one-month apart in March-April 1998. The source was also monitored at very-high gamma-ray energies (TeV measurements) during the same period in an attempt to search for correlations between TeV variability and the evolution of the radio morphology on parsec scales. While the VLBI maps show no temporal changes in the Mkn 421 VLBI jet, there is strong evidence of complex variability in both the total and polarized fluxes of the VLBI core of Mkn 421 and in its spectrum over the two-month span of our data. The high-energy measurements indicate that the overall TeV activity of the source was rising during this period, with a gamma-ray flare detected just three days prior to our second VLBI observing run. Although no firm correlation can be established, our data suggest that the two phenomena (TeV activity and VLBI core variability) are connected, with the VLBI core at 22 GHz being the self-absorbed radio counterpart of synchrotron self-Compton (SSC) emission at high energies. Based on the size of the VLBI core, we could derive an upper limit of 0.1 pc (3 x 10**17 cm) for the projected size of the SSC zone. This determination is the first model-free estimate of the size of the gamma-ray emitting region in a blazar.

description: The major simplification in a number of quantum integrable systems is the existence of special coordinates in which the eigenstates take a factorised form. Despite many years of studies, the basis realising the separation of variables (SoV) remains unknown in N=4 SYM and similar models, even though it is widely believed they are integrable. In this paper we initiate the SoV approach for observables with nontrivial coupling dependence in a close cousin of N=4 SYM - the fishnet 4D CFT. We develop the functional SoV formalism in this theory, which allows us to compute non-perturbatively some nontrivial observables in a form suitable for numerical evaluation. We present some applications of these methods. In particular, we discuss the possible SoV structure of the one-point correlators in presence of a defect, and write down a SoV-type expression for diagonal OPE coefficients involving an arbitrary state and the Lagrangian density operator. We believe that many of the findings of this paper can be applied in the N=4 SYM case, as we speculate in the last part of the article.

Influence of Domain Wall on Magnetocaloric Effect in GdPt$_{2}$

Year: 2006

description: The resistivity, magnetoresistance and in-field heat capacity measurements were performed on GdPt$_{2}$ intermetallic compound. The magnetocaloric parameters $ΔT_{ad}$ and $-ΔS$ were derived from the in-field heat capacity data. Comparison has been made between the magnetocaloric effect $-ΔS$ and difference in resistivity $-Δρ$ $(=ρ(H)-ρ(0))$ as a function of temperature. There is distinct difference in the temperature dependence of $-ΔS$ and $-Δρ$ below the ferromagnetic transition temperature. However after removing the domain wall contribution from $-Δρ$, the nature of $-ΔS$ and $-Δρ$ dependence as a function of temperature are similar. Our observation indicates that the domain wall contribution in magnetocaloric effect is negligible in spite of the fact that it has significant contribution in magnetotransport.

description: Model agnostic meta-learning (MAML) is a popular state-of-the-art meta-learning algorithm that provides good weight initialization of a model given a variety of learning tasks. The model initialized by provided weight can be fine-tuned to an unseen task despite only using a small amount of samples and within a few adaptation steps. MAML is simple and versatile but requires costly learning rate tuning and careful design of the task distribution which affects its scalability and generalization. This paper proposes a more robust MAML based on an adaptive learning scheme and a prioritization task buffer(PTB) referred to as Robust MAML (RMAML) for improving scalability of training process and alleviating the problem of distribution mismatch. RMAML uses gradient-based hyper-parameter optimization to automatically find the optimal learning rate and uses the PTB to gradually adjust train-ing task distribution toward testing task distribution over the course of training. Experimental results on meta reinforcement learning environments demonstrate a substantial performance gain as well as being less sensitive to hyper-parameter choice and robust to distribution mismatch.
How Hot is the Wind from TW Hydrae?

Publisher: name: arXiv

description: It has recently been suggested that the winds from Classical T Tauri stars in general, and the wind from TW Hya in particular, reaches temperatures of at least 300,000 K while maintaing a mass loss rate of $\sim 10^{-11}$ \Msol yr$^{-1}$ or larger. If confirmed, this would place strong new requirements on wind launching and heating models. We therefore re-examine spectra from the Space Telescope Imaging Spectrograph aboard the Hubble Space Telescope and spectra from the Far Ultraviolet Spectroscopic Explorer satellite in an effort to better constrain the maximum temperature in the wind of TW Hya. We find clear evidence for a wind in the \ion{C}{2} doublet at 1037 Åand in the \ion{C}{2} multiplet at 1335 Å. We find no wind absorption in the \ion{C}{4} 1550 Ådoublet observed at the same time as the \ion{C}{2} 1335 Åline or in observations of \ion{O}{6} observed simultaneously with the \ion{C}{2} 1037 Åline. The presence or absence of \ion{C}{3} wind absorption is ambiguous. The clear lack of a wind in the \ion{C}{4} line argues that the wind from TW Hya does not reach the 100,000 K characteristic formation temperature of this line. We therefore argue that the available evidence suggests that the wind from TW Hya, and probably all classical T Tauri stars, reaches a maximum temperature in the range of 10,000 -- 30,000 K.

description: We study stationary black holes in the presence of an external strong magnetic field. In the case where the gravitational backreaction of the magnetic field is taken into account, such an scenario is well described by the Ernst-Wild solution to Einstein-Maxwell field equations, representing a charged, stationary black hole immersed in a Melvin magnetic universe. This solution, however, describes a physical situation only in the region close to the black hole. This is due to the following two reasons: Firstly, Melvin spacetime is not asymptotically locally flat; secondly, the non-static Ernst-Wild solution is not even asymptotically Melvin due to the infinite extension of its ergoregion. All this might seem to be an obstruction to address an scenario like this; for instance, it seems to be an obstruction to compute conserved charges as this usually requires a clear notion of asymptotia. Here, we circumvent this obstruction by providing a method to compute the conserved charges of such a black hole by restricting the analysis to the near horizon region. We compute the Wald entropy, the mass, the electric charge, and the angular momentum of stationary black holes in highly magnetized environments from the horizon perspective, finding results in complete agreement with other formalisms.

description: We report measurements of the charmless semileptonic decays $B^0 \to π^- / ρ^- \ell^{+} ν$ and $B^+ \to π^0 / ρ^0 \ell^{+} ν$, based on a sample of $2.75 \times 10^8$ $B \bar{B}$ events collected at the $Υ(4S)$ resonance with the Belle detector at the KEKB $e^+e^-$ asymmetric collider. In this analysis, the accompanying $B$ meson is reconstructed in the semileptonic mode $B \to D^{(*)} \ell ν$, enabling detection of the signal modes with high purity. We measure the branching fractions ${\mathcal B}(B^0 \to π^- \ell^+ ν) = (1.38\pm 0.19\pm 0.14\pm 0.03) \times 10^{-4}$, ${\mathcal B}(B^0 \to ρ^- \ell^+ ν) = (2.17\pm 0.54\pm 0.31\pm 0.08) \times 10^{-4}$, ${\mathcal B}(B^+ \to π^0 \ell^+ ν) = (0.77\pm 0.14\pm 0.08\pm 0.00) \times 10^{-4}$ and ${\mathcal B}(B^+ \to ρ^0 \ell^+ ν) = (1.33\pm 0.23\pm 0.17\pm 0.05) \times 10^{-4}$, where the errors are statistical, experimental systematic, and systematic due to form-factor uncertainties, respectively. For each mode we also present the partial branching fractions in three $q^2$ intervals: $q^2 < 8$, $8 \leq q^2 < 16$, and $q^2 \geq 16$ GeV$^2/c^2$. From our partial branching fractions for $B \to π\ell ν$ and recent results for the form factor from unquenched Lattice QCD calculations, we obtain values of the CKM matrix element $|V_{ub}|$.
