description: The dominant uncertainty in the current measurement of the Hubble constant ($H_0$) with strong gravitational lensing time delays is attributed to uncertainties in the mass profiles of the main deflector galaxies. Strongly lensed supernovae (glSNe) can provide, in addition to measurable time delays, lensing magnification constraints when knowledge about the unlensed apparent brightness of the explosion is imposed. We present a hierarchical Bayesian framework to combine a dataset of SNe that are not strongly lensed and a dataset of strongly lensed SNe with measured time delays. We jointly constrain (i) $H_0$ using the time delays as an absolute distance indicator, (ii) the lens model profiles using the magnification ratio of lensed and unlensed fluxes on the population level and (iii) the unlensed apparent magnitude distribution of the SNe population and the redshift-luminosity relation of the relative expansion history of the Universe. We apply our joint inference framework on a future expected data set of glSNe, and forecast that a sample of 144 glSNe of Type~Ia with well measured time series and imaging data will measure $H_0$ to 1.5\%. We discuss strategies to mitigate systematics associated with using absolute flux measurements of glSNe to constrain the mass density profiles. Using the magnification of SNe images is a promising and complementary alternative to using stellar kinematics. Future surveys, such as the Rubin and \textit{Roman} observatories, will be able to discover the necessary number of glSNe, and with additional follow-up observations this methodology will provide precise constraints on mass profiles and $H_0$.

description: We investigate the relevance of quantum effects in the study of bulk tachyon dynamics. We analyze the behavior of a system which consists of a tachyon, the graviton and the dilaton through the use of the Wheeler-DeWitt equation in the mini-superspace approximation, The singular behavior of the classical solution for the system is modified so that the quantum behavior seems to be regular.

After describing their basic properties, we generalize decomposition to include orbifolds with these new phase factors, making a precise proposal for how such orbifolds are equivalent to disjoint unions of other orbifolds without trivially-acting subgroups or one-form symmetries, which we check in numerous examples.

description: We investigate the conjecture on the upper bound of the Lyapunov exponent for the chaotic motion of a charged particle around a Kerr-Newman black hole. The Lyapunov exponent is closely associated with the maximum of the effective potential with respect to the particle. We show that when the angular momenta of the black hole and particle are considered, the Lyapunov exponent can exceed the conjectured upper bound. This is because the angular momenta change the effective potential and increase the magnitude of the chaotic behavior of the particle. Furthermore, the location of the maximum is also related to the value of the Lyapunov exponent and the extremal and non-extremal states of the black hole.

description: Basic peculiarities of market price fluctuations are known to be well described by a recently developed random walk model in a temporally deforming quadric potential force whose center is given by a moving average of past price traces [Physica A 370, pp91-97, 2006]. By analyzing high-frequency financial time series of exceptional events such as bubbles and crashes, we confirm the appearance of nonlinear potential force in the markets. We show statistical significance of its existence by applying the information criterion. This new time series analysis is expected to be applied widely for detecting a non-stationary symptom in random phenomena.

description: We propose a formalism to extract the $γπ\toππ$ chiral anomaly $F_{3π}$ from calculations in lattice QCD performed at larger-than-physical pion masses. To this end, we start from a dispersive representation of the $γ^{(*)}π\toππ$ amplitude, whose main quark-mass dependence arises from the $ππ$ scattering phase shift and can be derived from chiral perturbation theory via the inverse-amplitude method. With parameters constrained by lattice calculations of the $P$-wave phase shift, we use this combination of dispersion relations and effective field theory to extrapolate two recent $γ^{(*)}π\toππ$ calculations in lattice QCD to the physical point. Our formalism allows us to extract the radiative coupling of the $ρ(770)$ meson and, for the first time, the chiral anomaly $F_{3π}=38(16)(11)\,\text{GeV}^{-3}$. The result is consistent with the chiral prediction albeit within large uncertainties, which will improve in accordance with progress in future lattice-QCD computations.

description: Photoinduced magnetization dynamics is investigated in chemically ordered $(\mathrm{LaMnO}_3)_{2n}/(\mathrm{SrMnO}_3)_n$ superlattices using the time-resolved magneto-optic Kerr effect. A monotonic frequency-field dependence is observed for the $n=1$ superlattice, indicating a single spin population consistent with a homogeneous hole distribution. In contrast, for $n\geq2$ superlattices, a large precession frequency is observed at low fields indicating the presence of an exchange torque in the dynamic regime. We propose a model that ascribes the emergence of exchange torque to the coupling between two spin populations -- viscous and fast spins.

description: The interplay of charmonium production and suppression in In+In and Pb+Pb reactions at 158 AGeV and in Au+Au reactions at sqrt(s)=200 GeV is investigated with the HSD transport approach within the `hadronic comover model' and the `QGP melting scenario'. The results for the J/Psi suppression and the Psi' to J/Psi ratio are compared to the recent data of the NA50, NA60, and PHENIX Collaborations. We find that, at 158 AGeV, the comover absorption model performs better than the scenario of abrupt threshold melting. However, neither interaction with hadrons alone nor simple color screening satisfactory describes the data at sqrt(s)=200 GeV. A deconfined phase is clearly reached at RHIC, but a theory having the relevant degrees of freedom in this regime (strongly interacting quarks/gluons) is needed to study its transport properties.

We show that the inclusion of vector-like fermions, required by $B$-physics data, leads to sizable modifications of the leading-log results derived within an Effective Field Theory approach. In the motivated parameter-space region relevant to the $B$-physics anomalies, the models predict a few per-mil decrease of the effective $W$-boson coupling to $τ$, within the reach of future experiments.

description: For an impact crater on land, scientists often need to estimate the impact energy according to the diameter of the impact crater. Since there is no unified formula to describe the complex physical process of impact, the results estimated by different scholars are quite different, which makes it difficult to judge which one is more consistent with the facts. For impact craters in the history of the earth, which have been unable to know the impact angle, there is an urgent need for a unified formula to obtain a more pertinent calculation result. After comparing and analysing several formulas put forward by previous scientists, we think that Eugene Shoemaker's formula in 1990 is better. We simplify and improve it in order to make it adapt to the calculation of very large impact energy, so as to avoid fallacies. At the end of the paper, we also give a general method to estimate the mass and volume of meteorites after obtaining the impact energy. The improved formula and method proposed in this paper can be used for reference by scholars, and this new formula is simple and easy to use, which can provide quick and reasonable results for scientists in related field.

description: The statistical equilibrium of neutral and ionised silicon in the solar photosphere is investigated. Line formation is discussed and the solar silicon abundance determined. High-resolution solar spectra were used to determine solar $\log gfε_{\rm Si}$ values by comparison with Si line synthesis based on LTE and NLTE level populations. The results will be used in a forthcoming paper for differential abundance analyses of metal-poor stars. A detailed analysis of silicon line spectra leads to setting up realistic model atoms, which are exposed to interactions in plane-parallel solar atmospheric models. The resulting departure coefficients are entered into a line-by-line analysis of the visible and near-infrared solar silicon spectrum. The statistical equilibrium of \ion{Si}{i} turns out to depend marginally on bound-free interaction processes, both radiative and collisional. Bound-bound interaction processes do not play a significant role either, except for hydrogen collisions, which have to be chosen adequately for fitting the cores of the near-infrared lines. Except for some near-infrared lines, the NLTE influence on the abundances is weak. Taking the deviations from LTE in silicon into account, it is possible to calculate the ionisation equilibrium from neutral and ionised lines. The solar abundance based on the experimental $f$-values of Garz corrected for the Becker et al.'s measurement is $7.52 \pm 0.05$. Combined with an extended line sample with selected NIST $f$-values, the solar abundance is $7.52 \pm 0.06$, with a nearly perfect ionisation equilibrium of $Δ\logε_\odot(\ion{Si}{ii}/\ion{Si}{i}) = -0.01$.

description: The propagator matrix "propagates" a full wave field from one depth level to another, accounting for all propagation angles and evanescent waves. The Marchenko focusing function forms the nucleus of data-driven Marchenko redatuming and imaging schemes, accounting for internal multiples. These seemingly different concepts appear to be closely related to each other. With this insight, the strong aspects of the propagator matrix (such as the handling of evanescent waves) can be transferred to the focusing function. Vice-versa, the propagator matrix inherits from the focusing function that it can be retrieved from the reflection response, which reduces its sensitivity to the subsurface model.

description: Extending the standard model with three right-handed neutrinos ($N_k$) and a second Higgs doublet ($η$), odd under the discrete parity symmetry $Z_2$, Majorana neutrino masses can be generated at 1-loop order. In the resulting model, the lightest stable particle, either a boson or a fermion, might be a dark matter candidate. Here we assume a specific mass spectrum ($M_1\ll M_2 < M_3 < m_η$) and derive its consequences for dark matter and collider phenomenology. We show that (i) the lightest right-handed neutrino is a warm dark matter particle that can give a $\sim$10% contribution to the dark matter density; (ii) several decay branching ratios of the charged scalar can be predicted from measured neutrino data. Especially interesting is that large lepton flavour violating rates in muon and tau final states are expected. Finally, we derive upper bounds on the right-handed neutrino Yukawa couplings from the current experimental limit on $Br(μ\to eγ)$.

description: We propose a theoretical framework to understand the observable charge-parity (CP) violation in charmless three-body $B^\pm$ decays. The decay amplitudes put together the $ππ\to KK $ re-scattering and the U-spin symmetry, treated within a CPT invariant framework. This approach applied to a two-channel model provides the magnitudes and signs of the ratios of the global CP asymmetries for $B^\pm \to K^\pm π^+ π^- \,$, $B^\pm \to K^\pm K^+ K^- \,$, $B^\pm \to π^\pm K^+ K^- \,$ and $B^\pm \to π^\pm π^+π^- \,$ decays, compatible with those obtained from the available experimental data. In addition, by considering the neutral channels we predict the ratios for the global CP asymmetries for these decays.

Muonium chemistry in condensed media
Creators: name: Ng, Chi Biu William
Publisher: name: University of British Columbia
Year: 2010

description: Muonium (u⁺e⁻, chemical symbol Mu) consists of an orbital electron associated with a positive muon as nucleus. It can be regarded as a very light 'isotope' of the hydrogen atom because it has essentially the same Bohr radius and ionization energy. Thus it can be used as a sensitive probe of isotope effects and of H-atom reactions which cannot be studied by conventional techniques. Due to the unique nuclear spin properties of the muon, there are several techniques available for investigation. These include muon spin rotation (μSR), muonium spin rotation (MSR) and muonium radical spin rotation (MRSR) in transverse magnetic fields, as used in this study. Various fundamental aspects of muonium formation and of chemical reaction kinetics have been explored by the experiments presented in this thesis. These are summarized below. (i) From the magnetic field dependence, it was verified that Mu does not react chemically with water to any significant extent. Its observed spontaneous slow spin relaxation arises from experimental artifacts such as magnetic field inhomogeneities and/or Mu-frequency beating. (ii) The MRSR technique was used to observe and identify muonium-substituted free radicals via their pair of precession frequencies in high transverse magnetic fields in pure benzene, pure styrene, and their mixtures. The results have implications regarding the mechanism of radical formation and selectivity, (iii) Both μSR and MSR experiments were performed on neopentane (liquid & solid) and concentrated KOH solutions. The μ⁺ and Mu yields in these systems indicated that a spur model of Mu formation is neither appropriate nor adequate to explain the results, (iv) In muonium solution kinetic studies, the reaction Mu + OH[sub=aq; sub=-] was found to be relatively slow, with a substantial activation energy (E ) and no kinetic isotope effect compared to H at room temperature. The reaction shows Mu behaving as a "muonic" acid, (v) Kinetic studies of the abstraction of D by Mu from DCO₂⁻ as a solute in water gave a large E[sub=a]. Upon comparison with HCO₂⁻, the isotope effects (k[sub=M]/k[sub=H] and k[sup=I; sub=D]/k[sub=I; sub=D]) imply that quantum mechanical tunnelling does not dominate the abstraction of H and D atoms in HC0₂⁻ and DC0₂⁻ by either H or Mu at room temperature, (vi) The MSR technique was used to initiate a study of model biological systems (various solutes incorporated in cyclodextrins and micelles). The results demonstrated the sensitive and non-destructive nature of the MSR technique, (vii) Hydrocarbons were also investigated: including measuring their muon yields, their temperature dependence, the effect of an external electric field, and yields in solvent mixtures. Almost all the data obtained seem to be at variance with the expectations of significant intra-spur processes in Mu formation, but are consistent with that of a 'hot atom' mechanism.

description: Orientifolds of type II string theory admit a certain set of generalized NS-NS fluxes, including not only the three-form field strength H, but also metric and non-geometric fluxes, which are related to H by T-duality. We describe in general how these fluxes appear as parameters of an effective N=1 supergravity theory in four dimensions, and in particular how certain generalized NS-NS fluxes can act as charges for R-R axions, leading to D-term contributions to the effective scalar potential. We illustrate these phenomena in type IIB with the example of a certain orientifold of T^6/Z_4.

description: Anxiety disorders refer to a list of psychiatric disorders which include Generalized Anxiety Disorder (GAD), Social Anxiety Disorder (SAD), Panic Disorder (PD), Specific Phobias (SP), agoraphobia, and Separation Anxiety Disorder. Although anxiety can be a normal reaction to stress and can be beneficial in some situations, excessive feelings of anxiety can be debilitating and prevent people from functioning in their daily lives. Anxiety disorders often occur alongside other mental disorders, including depression and substance use. EPIDEMIOLOGY Anxiety disorders have an earlier age of onset than other mental disorders and typically begin in childhood and adolescence. The median age of onset is at 11 years of age. However, some individuals will present in adulthood. The most common types of anxiety disorders include Specific Phobias (SP) and Social Anxiety Disorder (SAD). According to studies in the United States, SP affects 8.7 percent of the population, SAD affects 6.8 percent of the population, GAD affects 3.1 percent, and PD affects 2.7 percent of the general population. Women are twice as likely to be affected as men, although no significant difference has been found between genders in SAD. SAD, GAD, and PD are the most prevalent amongst white Americans, while PTSD is more predominant in African Americans.The scarcity of known biomarkers of anxiety disorders and the fact that some people do not respond to current therapies, require further research. Identification of novel biomarkers can lead to new prognostic, diagnostic, and therapeutic insights into anxiety disorders. Screening for biomarkers could also tell us about genetic susceptibility to anxiety disorders.

description: The preformation factor quantifies the probability of α particles preforming on the surface of the parent nucleus in decay theory and is closely related to the study of α clustering structure. In this work, a multilayer perceptron and autoencoder (MLP + AE) hybrid neural network method is introduced to extract preformation factors within the generalized liquid drop model and experimental data. A K-fold cross validation method is also adopted. The accuracy of the preformation factor calculated by this improved neural network is comparable to the results of the empirical formula. MLP + AE can effectively capture the linear relationship between the logarithm of the preformation factor and the square root of the ratio of the decay energy, further verifying that Geiger-Nuttall law can deal with preformation factor. The extracted preformation probability of isotope and isotone chains show different trends near the magic number, and in addition, an odd-even staggering effect appears. This means that the preformation factors are affected by closed shells and unpaired nucleons. Therefore the preformation factors can provide nuclear structure information. Furthermore, for 41 new nuclides, the half-lives introduced with the preformation factors reproduce the experimental values as expected. Finally, the preformation factors and α-decay half-lives of Z = 119 and 120 superheavy nuclei are predicted.

description: While galactic bulges may contain no significant dust of their own, the dust within galaxy discs can strongly attenuate the light from their embedded bulges. Furthermore, such dust inhibits the ability of observationally-determined inclination corrections to recover intrinsic (i.e. dust free) galaxy parameters. Using the sophisticated 3D radiative transfer model of Popescu et al. and Tuffs et al., together with Driver et al.'s recent determination of the average face-on opacity in nearby disc galaxies, we provide simple equations to correct (observed) disc central surface brightnesses and scalelengths for the effects of both inclination and dust in the B, V, I, J and K passband. We then collate and homogenise various literature data sets and determine the typical intrinsic scalelengths, central surface brightnesses and magnitudes of galaxy discs as a function of morphological type. All galaxies have been carefully modelled in their respective papers with a Sersic bulge plus an exponential disc. Using the bulge magnitude corrections from Driver et al., we additionally derive the average, dust-corrected, bulge-to-disc flux ratio as a function of galaxy type. With values typically less than 1/3, this places somewhat uncomfortable constraints on some current semi-analytic simulations. Typical bulge sizes, profile shapes, surface brightnesses and deprojected densities are provided. Finally, given the two-component nature of disc galaxies, we present luminosity-size and (surface brightness)-size diagrams for discs and bulges. We also show that the distribution of elliptical galaxies in the luminosity-size diagram is not linear but strongly curved.

description: [Objectives] To establish a simple, rapid and accurate method for identifying the genetic relationship of hybrid rice varieties to their parents. [Methods] Taking F1 hybrids Liangyou 336, Deliangyou Huazhan, and the parents of Liangyou 336, i.e., C815S (♀) and R336 (♂), as experimental materials, the genetic relationship of the hybrid rice varieties to the parental materials was identified by way of PCR amplification with the 48 pairs of SSR primers of Protocol for Identification of Rice Varieties: SSR Marker Method (NY/T 1433-2014). [Results] The genetic relationship of the hybrid rice varieties could be determined by comparing the PCR amplification products of the mixed DNA of the parents and the DNA of the F1 hybrids. [Conclusions] This method not only reduced the number of samples required but also had a good visual effect and high accuracy.

description: We report the analysis of the deep (270 ks) X-ray Chandra data of one of the most radio-loud, Seyfert 2 galaxies in the nearby Universe (z=0.01135), IC 5063. The alignment of the radio structure with the galactic disk and ionized bi-cone, enables us to study the effects of both radio jet and nuclear irradiation on the interstellar medium (ISM). The nuclear and bi-cone spectra suggest a low photoionization phase mixed with a more ionized or thermal gas component, while the cross-cone spectrum is dominated by shocked and collisionally ionized gas emission. The clumpy morphology of the soft (<3 keV) X-ray emission along the jet trails, and the large (~2.4 kpc) filamentary structure perpendicular to the radio jets at softer energies (<1.5 keV), suggest a large contribution of the jet-ISM interaction to the circumnuclear gas emission. The hard X-ray continuum (>3 keV) and the Fe K-alpha 6.4 keV emission are both extended to kpc size along the bi-cone direction, suggesting an interaction of nuclear photons with dense clouds in the galaxy disk, as observed in other Compton Thick (CT) active nuclei. The north-west cone spectrum also exhibits an Fe XXV emission line, which appears spatially extended and spatially correlated with the most intense radio hot-spot, suggesting jet-ISM interaction.

description: The experiment was conducted in the abandoned land of Liangjia Village, Huayin City, Shaanxi Province from April to September 2019. The experimental crop was spring maize. A total of six treatments were set up in a randomized block design. The moisture content of the top 0-60 cm soil was determined regularly, and the yield and quality indices of maize at maturity were checked. The results show that: (i) combined organic-inorganic fertilization increased the yield of spring maize by 3% ~ 8%. (ii) Compared with CK, fertilization treatments significantly improved the water use efficiency of spring maize, with an increase of 59.2%. The average water use efficiency of three combined organic-inorganic fertilization treatments was 27.81 kg/(ha • mm). Compared with CON, combined application of organic and inorganic fertilizers significantly improved the water use efficiency of spring maize, with an increase of 12.5%. (iii) The combined application of organic and inorganic fertilizers increased the moisture, total starch, crude protein and crude fat contents, and reduced crude fiber content of maize kernels. However, with the increase of the proportion of organic fertilizer, the crude protein content of maize kernels decreased. (iv) Yield of spring maize showed a significant parabolic relationship with soil water consumption. In summary, 70% inorganic fertilizer + 30% organic fertilizer is a scientific and reasonable way of fertilization.

description: In order to choose a numerical method for solving the time dependent equations of radiative transport, we obtain an exact solution for the time dependent radiation field in a one dimensional infinite medium with monochromatic, isotropic scattering for sources with an arbitrary spatial distribution and an arbitrary time variation of their power. The Lax-Wendroff method seems to be the most suitable. Because it is assumed that radiation delay is caused by the finite speed of light, the following difficulty arises when the numerical method is used: the region of variation of the variables (dimensionless coordinate τand time t) is triangular (the inequality τ< t). This difficulty is overcome by expanding the unknown functions in series in terms of small values of the time and coordinate. By comparing the numerical and exact solutions for a point source with a given time dependence for its power and with pure scattering, the steps in the variables required to obtain a desired accuracy are estimated. This numerical method can be used to calculate the intensity and polarization of the radiation from sources in the early universe during epochs close to the recombination epoch.

description: The great success of deep learning (DL) has inspired researchers to develop more accurate and efficient symbol detectors for multi-input multi-output (MIMO) systems. Existing DL-based MIMO detectors, however, suffer several drawbacks. To address these issues, in this paper, we develop a model-driven DL detector based on variational Bayesian inference. Specifically, the proposed unrolled DL architecture is inspired by an inverse-free variational Bayesian learning framework which circumvents matrix inversion via maximizing a relaxed evidence lower bound. Two networks are respectively developed for independent and identically distributed (i.i.d.) Gaussian channels and arbitrarily correlated channels. The proposed networks, referred to as VBINet, have only a few learnable parameters and thus can be efficiently trained with a moderate amount of training samples. The proposed VBINet-based detectors can work in both offline and online training modes. An important advantage of our proposed networks over state-of-the-art MIMO detection networks such as OAMPNet and MMNet is that the VBINet can automatically learn the noise variance from data, thus yielding a significant performance improvement over the OAMPNet and MMNet in the presence of noise variance uncertainty. Simulation results show that the proposed VBINet-based detectors achieve competitive performance for both i.i.d. Gaussian and realistic 3GPP MIMO channels.

description: [Objectives] The purpose of this study was to provide reference for cultivation and promotion of a new sugarcane variety Yuetang 03-373, on the basis of analyzing and summarizing the characters of the variety. [Methods] Correlation, multiple regression and path analyses were performed for the yield and yield components of Yuetang 03-373. [Results] Correlation analysis shows that cane yield was significantly correlated with millable stalk number, stalk length and stalk diameter, and among them, the correlation with millable stalk number was the strongest. Multiple regression and path analyses show that millable stalk number contributed the most to cane yield, followed by stalk length, and stalk diameter contributed the least. The regression equation of cane yield against the three yield components was y = -2.871 3 + 1.549 7 x1 + 5.899 0 x2 - 395.429 4 x3 (R = 0.967 2**). [Conclusions] Millable stalk number and stalk length were the important and major factors for high yield of Yuetang 03-373, indicating that Yuetang 03-373 is a sugarcane variety of millable stalk type. In cultivation, full play should be given to the advantage of Yuetang 03-373 in millable stalk number, as well as stalk length (plant height), in order to achieve the purpose of increasing yield.

description: We provide a detailed analysis of our previously proposed scheme [Phys. Rev. Lett. 88, 180401, (2002)] to engineer the profile of the hopping amplitudes for atomic gases in a 1D optical lattice so that the particle number becomes fractional. We consider a constructed system of a dilute two-species gas of fermionic atoms where the two components are coupled via a coherent electromagnetic field with a topologically nontrivial phase profile. We show both analytically and numerically how the resulting atomic Hamiltonian in a prepared dimerized optical lattice with a defect in the pattern of alternating hopping amplitudes exhibits a fractional fermion number. In particular, in the low-energy limit we demonstrate the equivalence of the atomic Hamiltonian to a relativistic Dirac Hamiltonian describing fractionalization in quantum field theory. Expanding on our earlier argument [Phys. Rev. Lett. 91, 150404 (2003)] we show how the fractional eigenvalues of the particle number operator can be detected via light scattering. In particular, we show how scattering of far-off resonant light can convey information about the counting statistics of the atoms in an optical lattice, including state-selective atom density profiles and atom number fluctuations. Optical detection could provide a truly quantum mechanical measurement of the particle number fractionalization in a dilute atomic gas.
