description: We used the standard geometrical thin accretion theory to obtain the accretion rates in Seyfert 1 galaxies and quasars. Combining accretion rates with the bolometric luminosity, we obtained the accretion efficiency. We found most of Seyfert 1 galaxies and radio quiet quasars have lower accretion efficiencies while most of the radio loud quasars possess higher accretion efficiencies. This finding further implies most of radio loud quasars possess Kerr black holes while Seyfert 1 galaxies and radio quiet quasars may not possess Kerr black holes. Considering the difference of the accretion efficiency we found there is a strong correlation between the accretion rate in units of the Eddington accretion rate and the width of the H$β$ emission line and most of AGNs are not accreting at Super-Eddington rates.

description: Among the innovations of the new century, social networking sites are increasingly affecting society. Today Social Media has gained so much power that it can make or break governments. Today we are exposed to a new kind of tool or weapon depending on how we use it. Today, many efforts are being made at the national and international level towards consumer empowerment. Internet is also being used in this direction. There was a time when consumers used to get limited information about a product or service and many times, they were unable to do anything even in the event of cheating. But today that view has changed to a great extent. The research article presented exposes how consumerism is associated with globalization, and how social networking sites are helping to empower consumers. The present paper is extracted from research being conducted by the authors on impacts of Social media on our lives.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: New type professional farmers are farmers who possess certain resources and capitals, have certain extent of spirit of entrepreneurship, and are fully capable of obtaining and allocating resources related to agricultural production and management, and engaged in agricultural production and management for obtaining average profit. Cultivation of new type professional farmers should be promoted in the process and at the background of “coordinated development of industrialization, informationization, urbanization and agricultural modernization”. It should establish a proper cultivation subject system consisting of government, enterprises, rural communities and nonprofit organizations. Relying on multiple motive forces, efforts should be concentrated on cultivating those farmers with enterprising, highly innovative and learning ability, to guide traditional farmers to change into learning, enterprising and innovative ones. In addition, cultivation of new type professional farmers must rely on farmer education and training, modern agricultural development, increase in agricultural comparative advantage, innovation of rural management system and mechanism, multiple types of agricultural operation on a fairly large scale, as well as construction and regulation of new rural communities. Finally, it is recommended to provide system guarantee from long-term input mechanism of new type professional farmer education and training, incentive and restrictive mechanism of new type professional farmer cultivation, and construction of favorable environment for agricultural entrepreneurship.

description: The effects of the generalized uncertainty principle({\bf GUP}) on the cosmological constant problem are discussed in the Schwarzchild-deSitter spacetime, through studying the corrections to its thermodynamics. We derive the correction to the Hawking temperature of the cosmological horizon, by a heuristic method enlighten by gr-qc/0106080 . The logarithmic correction to the Bekenstein-Hawking entropy is also obtained. For an ordinary star (not a black hole), the probable ratio of the vacuum energy to the total energy within the cosmological horizon is 2/3, which roughly coincides with the evidences from the astronomical observations. For a black hole, the ratio tends to decrease. An inequality associating the energy density with the length of system is put forward for understanding the smallness of the cosmological constant, and the relation between the Bekenstein entropy bound and the Bekenstein-Hawking entropy is also briefly discussed.

description: Affected by the meteorological disasters and market fluctuations, the growing area, yield and quality of cotton in Shandong Province have been reduced to varying degrees in recent years. The majority of farmers are regarded as the main body of agricultural production, whose enthusiasm for growing cotton and confidence in the cotton market play a significant role in stabilizing the growing area and improving the quality of cotton. We randomly select the cotton farmers for in-depth interview, to understand the situation of cotton cultivation and their state of mind for growing, aimed at deriving the factors influencing farmers' willingness to grow cotton. In the future, it is necessary to make the best use of the advantages and bypass the disadvantages, and in a timely manner curb the decline of cotton cultivation in the process of guiding and encouraging the cotton cultivation, in order to solve the problems of low farmers' willingness to grow cotton and sluggish cotton industry from the root.

description: A recently discovered young, high-velocity giant star J01020100-7122208 is a good candidate of hypervelocity star ejected from the Galactic center, although it has a bound orbit. If we assume that this star was ejected from the Galactic center, it can be used to constrain the Galactic potential, because the deviation of its orbit from a purely radial orbit informs us of the torque that this star has received after its ejection. Based on this assumption, we estimate the flattening of the dark matter halo of the Milky Way by using the Gaia DR2 data and the circular velocity data from Eilers et al. (2019). Our Bayesian analysis shows that the orbit of J01020100-7122208 favors a prolate dark matter halo within $\sim$ 10 kpc from the Galactic center. The posterior distribution of the density flattening $q$ shows a broad distribution at $q \gtrsim1$ and peaks at $q \simeq 1.5$. Also, 98.5\% of the posterior distribution is located at $q>1$, highly disfavoring an oblate halo.

description: The first-year WMAP data, in combination with any one of a number of other cosmic probes, show that we live in a flat Λ-dominated CDM universe with Ω_m ~ 0.27 and Ω_Λ~ 0.73. In this model the late-time action of the dark energy, through the integrated Sachs-Wolfe effect, should produce CMB anisotropies correlated with matter density fluctuations at z<2 (Crittenden & Turok 1996). The measurement of such a signal is an important independent check of the model. We cross-correlate the NRAO VLA Sky Survey radio source catalog (Condon et al. 1998) with the WMAP data in search of this signal, and see indications of the expected correlation. Assuming a flat Λ-CDM cosmology, we find Ω_Λ>0 (95% CL, statistical errors only) with the peak of the likelihood at Ω_Λ=0.68, consistent with the preferred WMAP value. A closed model with Ω_m=1.28, h=0.33, and no dark energy component (Ω_Λ=0), marginally consistent with the WMAP CMB TT angular power spectrum, would produce an anti-correlation between the matter distribution and the CMB. Our analysis of the cross-correlation of the WMAP data with the NVSS catalog rejects this cosmology at the 3σlevel.

description: The flux tube solutions in 5D Kaluza-Klein theory can be considered as a string-like object - $Δ-$string. The initial 5D metric can be reduced to some inner degrees of freedom living on the $Δ-$string. The propagation of electromagnetic waves through the $Δ-$string is considered. It is shown that the difference between $Δ$ and ordinary strings are connected with the fact that for the $Δ-$string such limitations as critical dimensions are missing.

description: In the past few years, augmented reality (AR) and virtual reality (VR) technologies have experienced terrific improvements in both accessibility and hardware capabilities, encouraging the application of these devices across various domains. While researchers have demonstrated the possible advantages of AR and VR for certain data science tasks, it is still unclear how these technologies would perform in the context of exploratory data analysis (EDA) at large. In particular, we believe it is important to better understand which level of immersion EDA would concretely benefit from, and to quantify the contribution of AR and VR with respect to standard analysis workflows. In this work, we leverage a Dataspace reconfigurable hybrid reality environment to study how data scientists might perform EDA in a co-located, collaborative context. Specifically, we propose the design and implementation of Immersive Insights, a hybrid analytics system combining high-resolution displays, table projections, and augmented reality (AR) visualizations of the data. We conducted a two-part user study with twelve data scientists, in which we evaluated how different levels of data immersion affect the EDA process and compared the performance of Immersive Insights with a state-of-the-art, non-immersive data analysis system.

description: Highly polarized QSOs discovered in the Two-Micron All Sky Survey (2MASS) have been observed to determine the source(s) of optical polarization in this near-infrared color-selected sample. Broad emission lines are observed in the polarized flux spectra of most objects, and the polarization of the lines is at about the same level and position angle as the continuum. Generally, the continuum is bluer and the broad-line Balmer decrement is smaller in polarized light than for the spectrum of total flux. Narrow emission lines are much less polarized than the broad lines and continuum for all polarized objects. These properties favor scattering by material close to a partially obscured and reddened active nucleus, but exterior to the regions producing the broad-line emission, as the source of polarized flux in 2MASS QSOs. The largely unpolarized narrow-line features require that the electrons or dust polarizing the light be located at distances from the nucleus not much greater than the extent of the narrow emission-line region. In addition to known high-polarization objects, four 2MASS QSOs with AGN spectral types of 1.9 and 2 were observed to search for hidden broad emission-line regions. Broad lines were detected in polarized light for two of these objects, and the polarizing mechanism appears to be the same for these objects as for the highly polarized QSOs in the sample that readily show broad emission lines in their spectra. The observations also show that starlight from the host galaxy contributes a significant amount of optical flux, especially for the narrow-line objects, and support the suggestion that many 2MASS QSOs are measured to have low polarization simply because of dilution of the polarized AGN light by the host galaxy.

description: We show that the path integral for the three-dimensional SU(2) BF theory with a Wilson loop or a spin network function inserted can be understood as the Rovelli-Smolin loop transform of a wavefunction in the Ashtekar connection representation, where the wavefunction satisfies the constraints of quantum general relativity with zero cosmological constant. This wavefunction is given as a product of the delta functions of the SU(2) field strength and therefore it can be naturally associated to a flat connection spacetime. The loop transform can be defined rigorously via the quantum SU(2) group, as a spin foam state sum model, so that one obtains invariants of spin networks embedded in a three-manifold. These invariants define a flat connection vacuum state in the q-deformed spin network basis. We then propose a modification of this construction in order to obtain a vacuum state corresponding to the flat metric spacetime.

description: The paper is a detailed analysis of two translations (English and Russian) of Kakinomoto no Hitomaro's (660-710) "The Elegy for My Dead Wife" (included in the first imperial anthology of Japanese poetry, "Man'yoshu"). This analysis focuses on the problem whether to avoid translating the so-called 'pillow-words' (makura-kotoba) - fixed epithets, which were one of the most important rhetorical figures in the old Japanese poetry. Many specialists find them conventional and thus lacking any important information. However, in spite of their conventionality, makura-kotoba play often an important role in constructing of the set of deep allusions within the structure of the poem.

description: The emission from PSR J1107-5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very bright. In order to improve our understanding of these state changes, we have identified archival data sets from the Parkes radio telescope in which the bright emission is present, and find that the emission never switches from the bright state to the weak state, but instead always transitions to the off state. Previous work had suggested the identification of the off state as an extreme manifestation of the weak state. However, the connection between the off and bright emission reported here suggests that the emission can be interpreted as undergoing only two emission states: a bursting state consisting of both bright pulses and nulls as well as the weak-emission state.

From Geometry to Logic

description: Transformation between five different intermediate forms used in VLSI design are discussed. The intermediate forms are: the D language, Akers' Diagrams, transistor listings, the sticks standard, and CIF language. They represent architecture, logic, transistor, topology and geometric levels, respectively. To understand more about the relationships between these levels, a series of transformations from the CIF to the sticks standard, from the sticks standard to the transistor listing, and from the transistor listing to the Akers' Diagram are presented. By doing this, the description gap between the logical world and the physical world is bridged.

CAD developers often complain about the lack of a model that can be applied uniformly throughout the entire design process. Akers' Diagrams seem to meet this demand. This work highlights this point.

As an example, a shift register implemented in NMOS technology will appear many times in this thesis.

description: Nearby young stellar moving groups have been identified by many research groups with different methods and criteria giving rise to cautions on the reality of some groups. We aim to utilise moving groups in an unbiased way to create a list of unambiguously recognisable moving groups and their members. For the analysis, two unsupervised machine learning algorithms (K-means and Agglomerative Clustering) are applied to previously known bona fide members of nine moving groups from our previous study. As a result of this study, we recovered six previously known groups (AB Doradus, Argus, $β$-Pic, Carina, TWA, and Volans-Carina). Three the other known groups are recognised as well; however, they are combined into two new separate groups (ThOr+Columba and TucHor+Columba).

description: The VLTI/GENIE configuration will operate using at least 4 of the VLTI telescopes (and possibly with one or more of the AT telescopes in the future if adaptive optics become available on them). GENIE effectively can be thought of as a 'smart' coronagraph, enabling high dynamic range imaging to be achieved at moderate spatial resolution, with high rejection of the emission of a central bright point source. However, but this bright source rejection may only provide a rather moderate image quality (due to the few baselines and transfer function on the sky). Operated in this way, only limited image reconstruction is possible since classical radio and millimeter wavelength interferometry techniques are not directly applicable to the outputs of optical interferometers because the absolute phases are generally not measured. However, measurements of visibility and closure phase could lead to situations where image reconstruction becomes possible. This paper addresses the issue of whether there are areas outside of the exoplanet search where it might be able to make a useful impact on astronomy.

description: A toolbox for the development and reduction of the dynamical models of nonequilibrium systems is presented. The main components of this toolbox are: Legendre integrators, dynamical postprocessing, and thermodynamic projector. Thermodynamic projector is the tool to transform almost arbitrary anzatz to a thermodynamically consistent model, the postprocessing is the cheapest way to improve the solution, obtained by the Legendre integrators. Legendre Integrators give the opportunity to solve linear equations instead of nonlinear ones for quasiequilibrium (MaxEnt) approximations. The essentially new element of this toolbox, the method of thermodynamic projector, is demonstrated on application to FENE-P model of polymer kinetic theory. The multy-peak model of polymer dynamics is developed. The simplest example, discussed in details, is the two peaks model for Gaussian manifold instability in polymer dynamics. This type of models opens a way to create the computational models for the "molecular individualism".

description: The effect of slip transfer on the deformation mechanisms of Al bicrystals was explored using a rate-dependent dislocation-based crystal plasticity model. Three different types of grain boundaries (GBs) were included in the model by modifying the rate of dislocation accumulation near the GB in the Kocks-Mecking law, leading to fully-opaque (dislocation blocking), fully-transparent and partially-transparent GBs. In the latter, slip transmission is only allowed in pairs of SS in neighbour grains that are suitably oriented for slip transfer according to the Luster-Morris parameter. Modifications of the GB character led to important changes in the deformation mechanisms at the GB. In general, bicrystals with fully-opaque boundaries showed an increase in the dislocation density near the GB, which was associated with an increase in the Von Mises stress. In contrast, the dislocation pile-ups and the stress concentration were less pronounced in the case of partially-transparent boundaries as the slip in one grain can progress into the next grain with some degree of continuity. No stress concentrations were found at these boundaries for fully-transparent boundaries, and there was continuity of strain across the boundary, which is not typical of most experimentally observed GBs. Simulations of ideal bicrystals oriented for favorable slip transfer on the most highly favored slip system in grains with high Schmid factors for slip transfer depends on the number of active SS in operation in the neighborhood and that most boundaries will lead to nearly opaque conditions while some boundaries will be transparent. Finally, the model was applied to a particular experimentally observed GB in which slip transfer was clearly operating indicating that the model predicted a nearly transparent GB.
Near-infrared spectroscopy of nearby Seyfert galaxies - II. Molecular content and coronal emission

description: We present sub-arcsec near-infrared 1.5 - 2.5 micron moderate resolution long-slit spectra of eight nearby Seyfert galaxies (z<0.01), both parallel to the ionization cone and perpendicular to it. These spectra complement similar data on six Seyferts, presented in Reunanen, Kotilainen & Prieto (2002). Large concentrations of molecular gas (H2) are present in the nucleus regardless of the Seyfert type. The spatial extent of the H2 emission is larger perpendicular to the cone than parallel to it in 6/8 (75 %) galaxies, in agreement with the unified models of Active Galactic Nuclei. Broad BrGamma was detected in nearly half of the optically classified Seyfert 2 galaxies, including two objects with no evidence for hidden polarized Broad Line Region. Nuclear [FeII] emission is generally blueshifted which together with high BrGamma/[FeII] ratios suggests shocks as the dominant excitation mechanism in Seyfert galaxies. Bright coronal emission lines [SiVI] and [SiVII] are common in Seyferts, as they are detected in ~60 % of the galaxies. In three galaxies the coronal lines are extended only in the direction parallel to the cone. This could be explained by shock excitation due to the jet or superwind interacting with the interstellar medium.

description: Stochastic gradient descent (SGD) is a key ingredient in the training of deep neural networks and yet its geometrical significance appears elusive. We study a deterministic model in which the trajectories of our dynamical systems are described via geodesics of a family of metrics arising from the diffusion matrix. These metrics encode information about the highly non-isotropic gradient noise in SGD. We establish a parallel with General Relativity models, where the role of the electromagnetic field is played by the gradient of the loss function. We compute an example of a two layer network.

description: We discuss the Swampland Distance Conjecture in the framework of black hole thermodynamics. In particular, we consider black holes in de Sitter space and we show that the Swampland Distance Conjecture is a consequence of the fact that apparent horizons are always inside cosmic event horizons whenever they exist in the case of fast-roll inflation. In addition, we show that the Bekenstein and the Hubble entropy bounds for the entropy in a region of spacetime lead similarly to the same conjecture.

description: We study the sensitivity limits of a broadband gravitational-waves detector based on dual resonators such as nested spheres. We determine both the thermal and back-action noises when the resonators displacements are read-out with an optomechanical sensor. We analyze the contributions of all mechanical modes, using a new method to deal with the force-displacement transfer functions in the intermediate frequency domain between the two gravitational-waves sensitive modes associated with each resonator. This method gives an accurate estimate of the mechanical response, together with an evaluation of the estimate error. We show that very high sensitivities can be reached on a wide frequency band for realistic parameters in the case of a dual-sphere detector.

description: Cardiovascular disease is the largest cause of death worldwide with a contribution of around 30% of global mortality. Screening for these diseases may be done by assessing the increase in arterial stiffness. This can be done by calculating carotid-femoral pulse-wave velocity (cf-PWV), a biomarker that can reliably be measured via, amongst others, laser-doppler vibrometry (LDV).A prototype utilizing this technology was developed within the scope of the CARDIS (& subsequently the INSIDE) project. By simultaneously measuring skin vibrations above main arteries such as the carotid and femoral arteries, cf-PWV can be estimated as PWV=∆x/PTT.The current prototype contains two handpieces equipped with an array of six laser beams each. A retroreflective patch is applied to the measurement site on which the laser beams are reflected, picking up the skin displacement information. From these time series, acceleration is derived. The peaks in the acceleration traces that correspond to the arrival of the heart-contraction induced pressure-wave are identified. The time delays between detected peaks that stem from the same heartbeat are called pulse-transit times (PTT). The distance between measurement sites is called ∆x.Ongoing work is being done on a new prototype lacking the need for the patches and on algorithms for both cf-PWV and more potential biomarkers present in the LDV data. New data is currently being measured by project partners at INSERM, within the scope of a clinical feasibility study in Paris. The potential use of chest vibration measurements for other biomarkers, relating to heart rhythm disfunction and carotid stenosis, is being investigated.

description: Automatically generating one medical imaging modality from another is known as medical image translation, and has numerous interesting applications. This paper presents an interpretable generative modelling approach to medical image translation. By allowing a common model for group-wise normalisation and segmentation of brain scans to handle missing data, the model allows for predicting entirely missing modalities from one, or a few, MR contrasts. Furthermore, the model can be trained on a fairly small number of subjects. The proposed model is validated on three clinically relevant scenarios. Results appear promising and show that a principled, probabilistic model of the relationship between multi-channel signal intensities can be used to infer missing modalities -- both MR contrasts and CT images.

Investigation of low-valent ruthenium aquo complexes

description: The work presented in this thesis investigates the synthesis of low oxidation state coordination complexes of ruthenium incorporating the anionic ligand, [CpCo(P(O)(OMe)_2)_3]-,(L_(OMe)). Several routes to RuL_(OMe)(H_2O)_3^+ are outlined. These routes produced two major products, possibly related by acid-base chemistry.

A new dimeric ruthenium aquo species with the proposed structure [Ru(III)L_(OMe)(H_2O)(µ-OH)_2OTs_2 was isolated. This complex does not provide a straightforward route to the target monomeric oxo compounds, but could conceivably provide a entry into synthesis of ruthenium dimers containing arnines and other ligands.

Finally, a new route to [Ru(IV)(H_20)(µ-O)]_2OTf_2 was discovered which is more convenient and is higher yielding than the previously published procedure.

description: The spin modulated gravitational wave signals, which we shall call smirches, emitted by stellar mass black holes tumbling and inspiralling into massive black holes have extremely complicated shapes. Tracking these signals with the aid of pattern matching techniques, such as Wiener filtering, is likely to be computationally an impossible exercise. In this article we propose using a mixture of optimal and non-optimal methods to create a search hierarchy to ease the computational burden. Furthermore, by employing the method of principal components (also known as singular value decomposition) we explicitly demonstrate that the effective dimensionality of the search parameter space of smirches is likely to be just three or four, much smaller than what has hitherto been thought to be about nine or ten. This result, based on a limited study of the parameter space, should be confirmed by a more exhaustive study over the parameter space as well as Monte-Carlo simulations to test the predictions made in this paper.
