description: In this contribution, we discuss the possible importance of continuum-coupling (or threshold) effects in heavy quarkonium spectroscopy. Our calculations are carried out in a coupled-channel model, where meson-meson higher Fock (or molecular-type) components are introduced in $Q \bar Q$ bare meson wave functions by means of a pair-creation mechanism. After providing a quick resume of the main characteristics of the coupled-channel model, we briefly discuss its application to the calculation of the masses of heavy quarkonium-like $χ_{\rm c}(2P)$ and $χ_{\rm b}(3P)$ states with threshold corrections. We show that the introduction of pair-creation effects in the Quark Model (QM) formalism makes it possible to explain the deviations of $χ_{\rm c}(2P)$ states' masses from the experimental data, without affecting the good QM description of the properties of $χ_{\rm b}(3P)$ states.

description: The well-known results concerning a dilute Bose gas with the short-range repulsive interaction should be reconsidered due to a thermodynamic inconsistency of the method being basic to much of the present understanding of this subject. The aim of our paper is to propose a new way of treating the dilute Bose gas with an arbitrary strong interaction. Using the reduced density matrix of the second order and a variational procedure, this way allows us to escape the inconsistency mentioned and operate with singular potentials of the Lennard-Jones type. The derived expansion of the condensate depletion in powers of the boson density n=N/V reproduces the familiar result, while the expansion for the mean energy per particle is of the new form: E=2π\hbar^2 a n/m [1+128/(15 \sqrtπ)\sqrt{na^3}(1-5b/8a)+ ...], where a is the scattering length and b>0 stands for one more characteristic length depending on the shape of the interaction potential (in particular, for the hard spheres a=b). All the consideration concerns the zero temperature.

description: To constrain the nature of the very first stars, we investigate the collapse and fragmentation of primordial, metal-free gas clouds. We explore the physics of primordial star formation by means of three-dimensional simulations of the dark matter and gas components, using smoothed particle hydrodynamics, under a wide range of initial conditions, including the initial spin, the total mass of the halo, the redshift of virialization, the power spectrum of the DM fluctuations, the presence of HD cooling, and the number of particles employed in the simulation. We find characteristic values for the temperature, T ~ a few 100 K, and the density, n ~ 10^3-10^4 cm^-3, characterising the gas at the end of the initial free-fall phase. These values are rather insensitive to the initial conditions. The corresponding Jeans mass is M_J ~ 10^3 M_sun. The existence of these characteristic values has a robust explanation in the microphysics of H2 cooling, connected to the minimum temperature that can be reached with the H2 coolant, and to the critical density at which the transition takes place betweeb levels being populated according to NLTE, and according to LTE. In all cases, the gas dissipatively settles into an irregular, central configuration which has a filamentary and knotty appearance. The fluid regions with the highest densities are the first to undergo runaway collapse due to gravitational instability, and to form clumps with initial masses ~ 10^3 M_sun, close to the characteristic Jeans scale. These results suggest that the first stars might have been quite massive, possibly even very massive with M_star > 100 M_sun.

Implementing renormalization by removing the Minkowski contribution it is shown that although the Green function in the literature satisfies the usual Green function equation, it leads to pathological physical results.

Estimating kinetic temperature from H I 21 cm absorption studies: correction for the turbulence broadening
Creators: name: Koley, Atanu

Publisher: name: arXiv
Year: 2018
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Neutral hydrogen 21 cm transition is a useful tracer of the neutral interstellar medium. However, inferring physical condition from the observed 21 cm absorption and/or emission spectra is often not straightforward. One complication in estimating the temperature of the atomic gas is that the line width may have significant contribution from non-thermal broadening. We propose a formalism here to separate the thermal and non-thermal broadening using a self-consistent model of turbulence broadening of the HI 21 cm absorption components. Applying this novel method, we have estimated the spin and the kinetic temperature of diffuse Galactic neutral hydrogen, and found that a large fraction of gas has temperature in the unstable range. The turbulence is found to be subsonic or transonic in nature, and the clouds seem to have a bimodal size distribution. Assuming that the turbulence is magnetohydrodynamic in nature, the estimated magnetic field strength is of μG order, and is found to be uncorrelated with the HI number density.

description: We report non-local electrical measurements in a mesoscopic size two-dimensional (2D) electron gas in a GaAs quantum well in a hydrodynamic regime. Viscous electric flow is expected to be dominant when electron-electron collisions occur more often than the impurity or phonon scattering events. We observe a negative nonlocal resistance and attribute it to the formation of whirlpools in the electron flow. We use the different nonlocal transport geometries and compare the results with a theory demonstrating the significance of hydrodynamics in mesoscopic samples.

description: We report preliminary results from an arcsecond-resolution X-ray survey of nearby galaxies using ACIS on board Chandra. The total sample consists of 41 low-luminosity AGNs, including Seyferts, LINERs, and LINER/H II transition objects. In the initial subsample of 24 objects observed thus far, we detect in 62% of the objects a compact, pointlike source astrometrically coincident with either the optical or radio position of the nucleus. The high detection rate strongly suggests that the majority of the objects do contain weakly active, AGN-like cores, presumably powered by central massive black holes. The 2-10 keV luminosities of the nuclear sources range from 10^38 to 10^41 erg/s, with a median value of 2x10^38 erg/s. Our detection limit corresponds to 8x10^37 erg/s for the typical sample distance of 12 Mpc; this limit is two orders of magnitude fainter than the weakest sources of this kind previously studied using ASCA or BeppoSAX. The new data extend toward lower luminosities the known linear correlation between hard X-ray and H-alpha luminosity for broad-line AGNs. Many narrow-line objects do contain X-ray cores, consistent with either weak AGNs or X-ray binary systems, but they have X-ray luminosities a factor of 10 below the L_X-L(Halpha) relation of the broad-line sources. Their distributions of photon energies show no indication of exceptionally high absorption. The optical line emission in these nuclei is likely powered, at least in part, by stellar processes.

description: An important step in diagnostics is the isolation of specific cells and microorganisms of interest from blood. Since such bioparticles are often present at very low concentrations, throughput needs to be as high as possible. In addition, to ensure simplicity, a minimum of sample preparation is important. Therefore, sorting schemes that function for whole blood are highly desirable. Deterministic lateral displacement (DLD) has proven to be very precise and versatile in terms of a wide range of sorting parameters. To better understand how DLD performs for blood as the hematocrit increases, we have performed measurements and simulations for spherical particles in the micrometer range moving through DLD arrays for different flow velocities and hematocrits ranging from pure buffer to whole blood. We find that the separation function of the DLD array is sustained, even though blood cells introduce a shift in the trajectories and a significant dispersion for particles that are close to the critical size in the device. Simulations qualitatively replicate our experimental observations and help us identify fundamental mechanisms for the effect of hematocrit on the performance of the DLD device.

Coulomb-correlation effects on the non-linear optical properties of realistic quantum wires

description: We review recent results on the linear and non-linear optical response of realistic quantum-wire structures. Our theoretical approach is based on a set of generalized semiconductor Bloch equations, and allows a full three-dimensional multisubband description of Coulomb correlation for any shape of the confinement profile, thus permitting a direct comparison with experiments for available state-of-the-art wire structures. Our results show that electron-hole Coulomb correlation removes the one-dimensional band-edge singularities from the absorption spectra, whose shape results to be heavily modified with respect to the ideal free-particle case over the whole range of photoexcited carrier densities.

We first give a proof of principle of the method using two empirical interatomic potential functions. We then apply the technique to feed information from an interatomic potential into otherwise inaccessible quantum mechanical tight-binding calculations of the reconstruction of partial dislocations in silicon at finite temperature. With this approach, comprehensive ab initio studies at finite temperature will now be possible.

Creators: name: Falà, Jacopo Francesco
Publisher: name: Zenodo
Year: 2019

description: Lo studio in oggetto, frutto di una notevole erudizione e di una evidente padronanza dell’argomento trattato, ha il merito di elaborare una originale ricostruzione storica che precisa il rapporto tra Descartes e la speculazione teologico-filosofica della cosiddetta seconda Scolastica in merito ai nessi tra le teorie angeleologiche comunemente accettate tra Cinque e Seicento e la dottrina cartesiana sull’anima. L’attenta valutazione del portato tardoscolastico viene affiancato da uno studio filologicamente rigoroso sulla tradizione platonica che innerva il Rinascimento e il milieu intellettuale francese contemporaneo a Descartes, con approfondimenti su autori generalmente poco frequentati. Su questo accurato panorama storico-filosofico delle possibili influenze dirette e indirette si innesta come punto di arrivo del saggio una ricognizione sull’elaborazione dottrinale cartesiana, considerata secondo il criterio evolutivo dello sviluppo cronologico del pensiero, con particolare attenzione al passaggio – che l’A. interpreta sostanzialmente nel senso di una discontinuit. (pp. 320- 333) – tra la prospettiva del Discours de la m.thode e quella delle Meditationes metaphysicae a riguardo del rapporto tra modelli angeleologici e teoria del cogito (nel Discours) / teoria della res cogitans (Meditationes).
Cost and demand elements in the inflationary process
Creators: name: Pitchford, J. D.
Publisher: name: The Australian National University
Year: 1958
Subjects: Inflation (Finance)

description: In order to describe an inflationary process it is necessary to have some knowledge of how prices and wages are determined. Conventional economic theory has regarded prices (and wages) as reacting to the level of excess demand or supply in the commodity (labour) market. Investigations have shown, however, that especially in manufacturing industries prices are often determined by applying a profit margin to variable costs., Some wages are also "cost determined", as for instance, in Australia where until recently the Commonwealth basic wage was adjusted quarterly to changes in the C. Series price index. A realistic analysis of inflation processes should allow for both cost and demand influences in price and wage determination. (First paragraph of Precis.)

description: One of the biggest challenges impeding the progress of Metal-Oxide-Silicon (MOS) quantum dot devices is the presence of disorder at the Si/SiO$_2$ interface which interferes with controllably confining single and few electrons. In this work we have engineered a low-disorder MOS quantum double-dot device with critical electron densities, i.e. the lowest electron density required to support a conducting pathway, approaching critical electron densities reported in high quality Si/SiGe devices and commensurate with the lowest critical densities reported in any MOS device. Utilizing a nearby charge sensor, we show that the device can be tuned to the single-electron regime where charging energies of $\approx$8 meV are measured in both dots, consistent with the lithographic size of the dot. Probing a wide voltage range with our quantum dots and charge sensor, we detect three distinct electron traps, corresponding to a defect density consistent with the ensemble measured critical density. Low frequency charge noise measurements at 300 mK indicate a 1/$f$ noise spectrum of 3.4 $μ$eV/Hz$^{1/2}$ at 1 Hz and magnetospectroscopy measurements yield a valley splitting of 110$\pm$26 $μ$eV. This work demonstrates that reproducible MOS spin qubits are feasible and represents a platform for scaling to larger qubit systems in MOS.

description: The sociological interest in the study presented here is in processes of organizational change as related to the economic order and to existing political arrangements. The study gives a description of the traditional system of caste and a survey of the economy of a rice producing village. It includes an analysis of conflicts between privileged high castes and underprivileged low castes. This situation is analyzed from point of view of the following generel developments: The dwindling of the power of the traditionally privileged groups in whose hands economic and political control had been vested. The economic and political advancement of subordinate castes and the disruption of the "feudal bond” and traditional loyalties. At the same time as traditional relationships of domination-subordination are gradually being replaced by contractual employer-employee relations with implicit bargaining, castes are being organized as action groups to achieve their objectives in either peaceful or violent fashion.

description: The present study is an attempt to build a fairly detailed description of the complete economic system as a working, living organism. The ultimate goals toward which the work is pointed are prediction, policy and economic health and welfare. This study makes two steps toward that goal. It firstly attempts to describe how the total organism works, by studying its major functional organs one by one, and then putting these together into an interrelated whole. This whole and its parts we may refer to as a complete 'model' of the macro-economy. The second step is to describe how this model can be used as an aid to economic forecasting, and the formulation of global economic policy. This requires a theory of the ultimate causes of economic change, of their prediction, and of the prediction of their impact and transmission through the economic system.

description: Design of microparticles which stabilize at the centerline of a channel flow when part of a dilute suspension is examined numerically for moderate Reynolds numbers ($10 \le Re \le 80$). Stability metrics for particles with arbitrary shapes are formulated based on linear-stability theory. Particle shape is parametrized by a compact, Non-Uniform Rational B-Spline (NURBS)-based representation. Shape-design is posed as an optimization problem and solved using adaptive Bayesian optimization. We focus on designing particles for maximal stability at the channel-centerline robust to perturbations. Our results indicate that centerline-focusing particles are families of characteristic "fish"/"bottle"/"dumbbell"-like shapes, exhibiting fore-aft asymmetry. A parametric exploration is then performed to identify stable particle-designs at different k's (particle chord-to-channel width ratio) and Re's ($0.1 \le k \le 0.4, 10 \le Re \le 80$). Particles at high-k's and Re's are highly stabilized when compared to those at low-k's and Re's. A comparison of the modified dumbbell designs from the current framework also shows better performance to perturbations in Fluid-Structure Interaction (FSI) when compared to the rod-disk model reported previously (Uspal & Doyle 2014) for low-Re Hele-Shaw flow. We identify basins of attraction around the centerline, which span larger release-angle-ranges and lateral locations (tending to the channel width) for narrower channels, which effectively standardizes the notion of global focusing in such configurations using the current stability-paradigm. The present framework is illustrated for 2D cases and is potentially generalizable to stability in 3D flow-fields. The current formulation is also agnostic to Re and particle/channel geometry which indicates substantial potential for integration with imaging flow-cytometry tools and microfluidic biosensing-assays.

Contributions to these changes include thermal expansion, recent melting of ice masses (Antarctica, Greenland, and mountain glaciers), and changes in terrestrial water storage. To quantify the contribution from recent mountain deglaciation, a global numerical model based on climate parameters is developed, incorporating seasonal variations in ice volume of 100 glaciated regions. The estimated melt-water from mountain glaciers contributed between 0.25 and 0.43 mm year−1 to global sea-level rise over the period 1961-1990, and between 0.47 and 0.58 mm year−1 over 1991-2000. This is consistent with directly observed ice-volume changes. Thus, confident predictions for future changes can be made using the same numerical model. It is predicted that mountain glaciers will contribute ~1.5 mm year−1 on average over the remainder of this century. As well as the volumetric effect of the melt-water, local sea level is affected by the deflection of the crust and geoid in response to the change in surface load. Relative sea-level is predicted to rise on most of the worlds coastlines, but at sites located close to the melting glaciers sea-level is predicted to fall at a rate that reaches several times the average value, and estimates of geodetic signals are therefore strongly dependent on the region under investigation. The distinctive geographical pattern of the changes due to mountain deglaciation is dependent on a number of other factors which have also been addressed in this study. These include both the total and regional ice-volume loss of glaciers, the spatial representation of the glaciated areas, and the Earth models used. As the predicted geodetic signals at sites located close to large-scale glacier systems are of a magnitude that can be observed with geodetic techniques, these methods can provide additional constraints on the ice-volume loss of mountain glaciers.
Nonequlibrium phase transition in the kinetic Ising model: Dynamical symmetry breaking by randomly varying magnetic field
Creators: name: Acharyya, Muktish

description: The nonequilibrium dynamic phase transition, in the two dimensional kinetic Ising model in presence of a randomly varying (in time but uniform in space) magnetic field, has been studied both by Monte Carlo simulation and by solving the mean field dynamic equation of motion for the average magnetisation. In both the cases, the time averaged magnetisation vanishes from a nonzero value depending upon the values of the width of randomly varying field and the temperature. The phase boundary lines are drawn in the plane formed by the width of the random field and the temperature.

description: The suppression of superconductivity by substitution effects has been measured in high quality single crystals of U(Pt_{1-x} Pd_x)_3 with 0 <= x <= 0.002. While the superconducting transition temperature T_c varies linearly with residual resistivity r_0, consistent with pair-breaking by impurity potential scattering, the rate of suppression of T_c with r_0 is much larger for Pd substitution than for other impurity substitutions or by increased defect density. This effect is correlated with an increase in the inelastic scattering coefficient, and may be related to Pd-induced changes in the magnetic fluctuation spectrum.

Economic change among the Siane tribes of New Guinea

subject: Economic anthropology

description: In 1933, when the New Guinea Highlands were first explored, the Siane people used only stone tools. During the succeeding 20 years steel tools have completely replaced stone ones. Until 1945 Europeans did not affect Siane life directly, although the stimulus for economic change came from the introduction of steel tools and European goods. For 12 years the direction and manner of economic change was determined by native society, its exchange relationships and values. Since 1945 the Siane have been visited and patrolled, and indentured labourers have gone to the coast. But related tribes to the south continue to use stone tools and were first visited by patrols in 1952. The area presents a unique opportunity for the study of economic change taking place autonomously (though under European stimuli), and involving technological innovation and the introduction of new consumer goods in a completely "native" society. The recency of events permits a simple historical reconstruction, while the nearby groups, which have changed less, confirm this reconstruction. (First paragraph of abstract).

description: We have used the Very Large Array (VLA) to conduct a survey for radio continuum emission in the sample of 52 Seyfert nuclei selected from the optical spectroscopic galaxy catalog of Ho, Filippenko, and Sargent. This Seyfert sample is the most complete and least biased available, and, as such, it will be useful for a variety of statistical analyses. Here we present the observations, measurements, and an atlas of radio maps. The observations were made at 6 cm in the B-array and at 20 cm in the A-array, yielding matched angular resolutions of approximately 1". We detected 44 objects (85%) at 6 cm and 37 objects (71%) at 20 cm above a 3-sigma threshold of 0.12 mJy/beam. The sources have a wide range of radio powers (10^{18}-10^{25} W/Hz), spectral indices (+0.5 to -1 between 20 and 6 cm), and linear sizes (from a few tens pc to 15 kpc). The morphology of the radio emission is predominantly that of a compact core, either unresolved or slightly resolved, occasionally accompanied by elongated, jet-like features. Linearly polarized emission was detected at 6 cm in 12 sources, 9 of which were also detected at 20 cm.

Origin of 1I/'Oumuamua. I. An ejected protoplanetary disk object?

description: 1I/'Oumuamua is the first interstellar interloper to have been detected. Because planetesimal formation and ejection of predominantly icy objects are common by-products of the star and planet formation processes, in this study we address whether 1I/'Oumuamua could be representative of this background population of ejected objects. The purpose of the study of its origin is that it could provide information about the building blocks of planets in a size range that remains elusive to observations, helping to constrain planet formation models. We compare the mass density of interstellar objects inferred from its detection to that expected from planetesimal disks under two scenarios: circumstellar disks around single stars and wide binaries, and circumbinary disks around tight binaries. Our study makes use of a detailed study of the PanSTARRS survey volume; takes into account that the contribution from each star to the population of interstellar planetesimals depends on stellar mass, binarity, and planet presence; and explores a wide range of possible size distributions for the ejected planetesimals, based on solar system models and observations of its small-body population. We find that 1I/'Oumuamua is unlikely to be representative of a population of isotropically distributed objects, favoring the scenario that it originated from the planetesimal disk of a young nearby star whose remnants are highly anisotropic. Finally, we compare the fluxes of meteorites and micrometeorites observed on Earth to those inferred from this population of interstellar objects, concluding that it is unlikely that one of these objects is already part of the collected meteorite samples.

description: In this thesis, the causes, nature and effects of Indian immigration and settlement in Fiji from 1879 to 1919 are studied from documentary and oral data. The subject is treated broadly from several angles, not analysed rigorously in relation to any single hypothesis. Indentured Indian immigrants were introduced into Fiji by the first Governor, Sir Arthur Gordon, who wished to obtain revenue from a limited commercial development of the colony without disrupting Fijian society. This object was successfully achieved but at the price of creating other problems for the future. Investment of Australian capital in the sugar industry ensured the continuance of the immigration.

Spiky Phases of Smooth Membranes. Implications for Smooth Strings
Creators: name: Kleinert, H.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We point out a possible mechanism by which smooth surfaces can become spiky as the constant of curvature stiffness $κ$ falls below certain critical values. This happens either in a single first-order transition, or in a sequence of two Kosterlitz-Thouless-like transitions. There may also be additional phases in which the spikes form a hexagonal solid-like array or a disordered liquid-like structure. Our discussion suggests that there exist smooth strings between quarks.

description: Chapter 1 Introduction - The study of paleomagnetism has for its objective the description of the behaviour of the Earth's magnetic fied in past ages. It may also be applied to certain economic problems. The results described in this thesis provide information about the geomagnetic field in Australia during the Kainozoic and Palaeozoic. Results are presented regarding the phenomena of polar wandering, reversals in the polarity of the field and its secular variation. There is also a chapter dealing with two problems in economic geophysics.

description: We present a time-dependent uniform-density interior Schwarzschild solution, an exact solution to the Einstein field equations. Our solution describes the collapse (or the time-reversed expansion) of an object from an infinite radius to an intermediate radius of 9/8 of the Schwarzschild radius, at which time a curvature singularity appears at the origin, and then continues beyond the singularity to a gravastar with radius equal to the Schwarzschild radius.
