description: We have measured the melting curve of $^4$He in the temperature range from 10 to 400 mK with the accuracy of about 0.5 $μ$bar. Crystals of different quality show the expected $T^4$-dependence in the range from 80 to 400 mK without any sign of the supersolid transition, and the coefficient is in excellent agreement with available data on the sound velocity in liquid $^4$He and on the Debye temperature of solid $^4$He. Below 80 mK we have observed a small deviation from $T^4$-dependence which however cannot be attributed to the supersolid transition because instead of decrease the entropy of the solid rather remains constant, about $2.5\times10^{-6}$ $R$

description: This paper is the fourth in a series whose goal is to develop a fundamentally new way of building theories of physics. The motivation comes from a desire to address certain deep issues that arise in the quantum theory of gravity. Our basic contention is that constructing a theory of physics is equivalent to finding a representation in a topos of a certain formal language that is attached to the system. Classical physics arises when the topos is the category of sets. Other types of theory employ a different topos. The previous papers in this series are concerned with implementing this programme for a single system. In the present paper, we turn to considering a collection of systems: in particular, we are interested in the relation between the topos representation for a composite system, and the representations for its constituents. We also study this problem for the disjoint sum of two systems. Our approach to these matters is to construct a category of systems and to find a topos representation of the entire category.

description: A long-standing open problem in the semantics of programming languages supporting probabilistic choice is to find a commutative monad for probability on the category DCPO. In this paper we present three such monads and a general construction for finding even more. We show how to use these monads to provide a sound and adequate denotational semantics for the Probabilistic FixPoint Calculus (PFPC) -- a call-by-value simply-typed lambda calculus with mixed-variance recursive types, term recursion and probabilistic choice. We also show that in the special case where we consider continuous dcpo's, then all three monads coincide with the valuations monad of Jones and we fully characterise the induced Eilenberg-Moore categories by showing that they are all isomorphic to the category of continuous Kegelspitzen of Keimel and Plotkin.

description: We present an automated method for registration and mosaicking of multimodal technical images of artworks based on mutual information. We focus on the registration of element distribution maps resulting from macro X-ray fluorescence (MA-XRF) scanning, which can be considered as a layered stack and treated as the moving image. The target fixed image is the visible image of the same artwork. In consecutive stages, a unique, optimised transformation that provides the highest average mutual information across all images in the stack is identified with consensus. This transformation can be applied to the moving image to obtain the best alignment between the moving and fixed images when overlapped.

description: We have developed a method to calculate overdensities in multicolour surveys, facilitating a direct comparison of the local density contrast measured using galaxy samples that have different redshift error distributions, i.e. for red and blue, or bright and faint galaxies, respectively. We calculate overdensities in small redshift slices (Delta z =0.02, which at z=0.3 corresponds roughly to Delta r_comoving=53 h^-1 Mpc) for 9176 galaxies with R<=23.65, M_B(Vega)-5log h<=-18, and z<= 0.7, in three COMBO-17 fields (measuring 31'X 31' each). The mean redshift errors of this sample are approximately sigma_z/(1+z)~0.015. In the Chandra Deep Field South we identify a region that is underdense by almost a factor 2 compared to the other two fields in the same redshift range (0.25

Skeletal muscle metabolism during exercise : an in vivo ³¹P nuclear magnetic resonance study
Creators: name: Matheson, Gordon Omar
Publisher: name: University of British Columbia
Year: 2011

description: The metabolic and biochemical adaptations which set the endurance limit in skeletal muscle and are modified by physical training, and those which set the fatigue limits in conditions of chronic hypoxia, are not completely understood. Therefore, the purpose of this study was to measure the key metabolites involved in the control of oxidative and glycolytic metabolism, during the elevated metabolic demands of exercise, in subject groups which were separated by distinct differences in their training status or by their exposure to chronic hypobaric hypoxia. Since repeated measures of the key metabolites involved in energy metabolism (PCr, Pi, ATP) and intracellular pH (pHm) would be exceedingly difficult using the conventional muscle needle biopsy technique, ³¹P NMR was selected as an appropriate, noninvasive method for measuring these metabolites. Two separate exercise models were developed for use within a 1.0 m bore NMR machine. An electrical stimulation model using the rectus femoris muscle was developed and the factors which influenced reliability and reproducibility of the data were determined. In addition, a dynamic exercise model was developed in which the gastrocnemius muscle was exercised in a mechanical calf ergometer. The results of the experiments using the electrical stimulation model indicate that RF coil geometry, stimulation intensity and duty cycle, electrode placement, and subject tolerance require very close control for the model to be reliable. It is felt that this model is best suited for experiments which require a within-subject design and is ideally suited for experimental or therapeutic intervention studies. The calf ergometer was used to compare sedentary lowlanders, marathon and ultramarathon runners, power trained athletes, and Quechua Indians, native to altitudes of 4,200 m in the Andes, before and after deacclimation to sea level. It was found that the Andean natives did not possess a standard physiological phenotype with respect to aerobic and anaerobic capacities. In addition, given the Andean's very low anaerobic capacity and intermediate aerobic capacity, this group performed calf work equivalent to that of highly trained endurance and power athletes. Moreover, pHm, PCr, Pi, and ATP showed equivalent perturbation at fatigue and in recovery compared with the marathon runners but considerably less perturbation than was found in the power trained athletes who possess equivalent aerobic capacities but far greater anaerobic capacities. NMR derivable estimates of the phosphorylation potential in this study support the theory that closer coupling between ATP supply-ATP demand may be responsible for reduced kinetic and thermodynamic activation of mitochondrial metabolism seen in the Andean natives.

description: In this work we characterize in detail the bifurcation leading to an excitable regime mediated by localized structures in a dissipative nonlinear Kerr cavity with a homogeneous pump. Here we show how the route can be understood through a planar dynamical system in which a limit cycle becomes the homoclinic orbit of a saddle point (saddle-loop bifurcation). The whole picture is unveiled, and the mechanism by which this reduction occurs from the full infinite-dimensional dynamical system is studied. Finally, it is shown that the bifurcation leads to an excitability regime, under the application of suitable perturbations. Excitability is an emergent property for this system, as it emerges from the spatial dependence since the system does not exhibit any excitable behavior locally.

From the sharp Hardy inequality we deduce the sharp constant in a Sobolev embedding which is optimal in the Lorentz scale. In the appendix, we characterize the cases of equality in the rearrangement inequality in fractional Sobolev spaces.

description: This study investigates the aural and visual factors that influence appropriateness perception in soundscape evaluations in residential spaces, where people may spend most of their time in. Appropriateness in soundscape is derived from the expectation of sound sources in a specific environment, place, or function heard by a listener. The appropriateness of soundscapes in 30 locations in an urban residential environment is investigated with varying landscape, visual, and aural elements through a questionnaire. Participants experienced the soundscape in situ and were asked to evaluate the appropriateness of soundscape as well as the dominance of specific sound sources such as traffic, human activities, and birdsongs in the residential space. The effect of the type of traffic on appropriateness is also investigated. A strong relationship is found between appropriateness and affective soundscape qualities such as pleasantness, highlighting the importance of considering appropriateness in soundscape research.

We find that this cooling can be optimized by a proper choice of relative ODT and $Λ$ beam polarizations. In this optimized configuration, we observe molecules with temperatures as low as 14(1) $μ$K in traps with depths up to 570 $μ$K. With optimized parameters, we transfer $\!\sim\!5$% of molecules from our radio-frequency magneto-optical trap into the ODT, at a density of $\sim\!2\times 10^{9}$ cm$^{-3}$, a phase space density of $\sim\!2\times 10^{-7}$, and with a trap lifetime of $\!\sim\!1$ s.

description: Gentrification--the transformation of a low-income urban area caused by the influx of affluent residents--has many revitalizing benefits. However, it also poses extremely concerning challenges to low-income residents. To help policymakers take targeted and early action in protecting low-income residents, researchers have recently proposed several machine learning models to predict gentrification using socioeconomic and image features. Building upon previous studies, we propose a novel graph-based multimodal deep learning framework to predict gentrification based on urban networks of tracts and essential facilities (e.g., schools, hospitals, and subway stations). We train and test the proposed framework using data from Chicago, New York City, and Los Angeles. The model successfully predicts census-tract level gentrification with 0.9 precision on average. Moreover, the framework discovers a previously unexamined strong relationship between schools and gentrification, which provides a basis for further exploration of social factors affecting gentrification.

description: Among the current advanced driver assistance systems, Vehicle-to-Vehicle (V2V) technology has great potential to increase Vehicular Ad Hoc Network (VANET) performance in terms of security, energy efficiency, and comfortable driving. In reality, vehicle drivers regularly change lanes depending on their assumptions regarding visual distances. However, many systems are not quite well-designed, because the visible range is limited, making it difficult to achieve such a task. V2V technology offers high potential for VANET to increase safety, energy efficiency, and driver convenience. Drivers can make more intelligent options in terms of lane selection using predicted information of downstream lane traffic, which is essential for obtaining mobility benefits.

On the Signatures of Gravitational Redshift: The Onset of Relativistic Emission Lines

description: Aims. We quantify the effect of gravitational redshift on emission lines to explore the transition region from the Newtonian to the Einsteinian regime. With the emitting region closer to the Kerr black hole, lines are successively subjected to a stronger gravitationally induced shift and distortion. Simulated lines are compared to broad, optical emission lines observed in Mrk 110. Methods. We simulate relativistic emission line profiles by using Kerr ray tracing techniques. Emitting regions are assumed to be thin equatorial rings in stationary Keplerian rotation. The emission lines are characterised by a generalized Doppler factor or redshift associated with the line core. Results. With decreasing distance from the black hole, the gravitational redshift starts to smoothly deviate from the Newtonian Doppler factor: Shifts of the line cores reveal an effect at levels of 0.0015 to 60% at gravitational radii ranging from 10^{5} to 2. This corresponds to fully relativistic Doppler factors of 0.999985 to 0.4048. The intrinsic line shape distortion by strong gravity i.e. very asymmetric lines occur at radii smaller than roughly ten gravitational radii. Conclusions. Due to the asymptotical flatness of black hole space-time, GR effects are ubiquitous and their onset can be tested observationally with sufficient spectral resolution. With a resolving power of ~100000, yielding a resolution of ~0.1 Angstroems for optical and near-infrared broad emission lines like Hβ, HeII and Paα, the gravitational redshift can be probed out to approximately 75000 gravitational radii.

Do radio jets drive ionized outflows in Low Excitation Radio Galaxies?
Creators: name: Singha, Mainak
Publisher: name: Zenodo
Year: 2020

description: The energetic feedback generated by the radiation pressure of the accretion disk or the radio jets in active galactic nuclei (AGNs) has been suggested to be able to produce fast ionized outflows, which can be studied using highly ionized emission lines. Radiation pressure from the accretion disk is thought to be the dominant driving mechanism in radio quiet AGN. However, detection of HI absorbing gas in outflow in Low Excitation Radio Galaxies (LERGs) as well as a correlation between [OIII] line width and radio power suggest that the radio jet in radio loud AGN may be capable of driving an outflow. We obtained SDSS spectroscopic data for 18 optically selected LERGs at 0.01< z <0.2 with low Eddington ratio to infer the kinematics of the highly ionized emission lines. We report that LERGs do show visible “blue-wings” and hence, are driving ionized outflows. The properties of the outflows (luminosities, velocities) are similar to those of optically selected AGN. In addition, we note that these LERGs belong to diverse categories of radio source – FR I, FR II and compact. This indicates that the radio jet might not be the major driving mechanism in launching the outflows in LERGs. If this is confirmed, it would suggest that low luminosity AGN (even those with an ADAF) are capable of driving a fast, ionized outflow.

description: We characterize the time evolution of a d-dimensional probability distribution by the value of its final entropy. If it is near the maximally-possible value we call the evolution mixing, if it is near zero we say it is purifying. The evolution is determined by the simplest non-linear equation and contains a d times d matrix as input. Since we are not interested in a particular evolution but in the general features of evolutions of this type, we take the matrix elements as uniformly-distributed random numbers between zero and some specified upper bound. Computer simulations show how the final entropies are distributed over this field of random numbers. The result is that the distribution crowds at the maximum entropy, if the upper bound is unity. If we restrict the dynamical matrices to certain regions in matrix space, for instance to diagonal or triangular matrices, then the entropy distribution is maximal near zero, and the dynamics typically becomes purifying.

description: A nation cannot hope to establish lasting conditions for peace unless it find ways of building mutual trust among its citizens through its educational system by creating a worldview that promotes mutual understanding, respect, reception and dialogue. Education needs to have a vision, to inspire the children’s mind, wake up their dreams, offer wings to their passion and thrust them into action towards the virtuousness of magnanimity; than merely stuffing-up the empty heads, to which Peace Education do contribute profoundly. Education is now largely focused to prepare young people for the employment market, not in moulding them into good citizens and responsible human beings. This implies a shift of attention from specific subject knowledge and skills towards a focus on attitudes, beliefs and behaviour. This makes it crucial to integrate the tenets of peaceful co-existence into the curricular aspects. The seeds of forbearance should be planted early in the hearts of children at the basic education level in order to raise a new generation of peace-loving citizens of this great country. We should always strive to ‘catch them young’ to make lasting impressions of righteousness in their mind. The field of peace education has significantly developed over the past decades towards constructive learning about conflict resolution, human rights, cooperative values, active communication, disarmament and peace-building. Despite the tremendous growth in the 20th century, peace education is still not the part of school systems in India
A General Theorem Relating the Bulk Topological Number to Edge States in Two-dimensional Insulators

description: We prove a general theorem on the relation between the bulk topological quantum number and the edge states in two dimensional insulators. It is shown that whenever there is a topological order in bulk, characterized by a non-vanishing Chern number, even if it is defined for a non-conserved quantity such as spin in the case of the spin Hall effect, one can always infer the existence of gapless edge states under certain twisted boundary conditions that allow tunneling between edges. This relation is robust against disorder and interactions, and it provides a unified topological classification of both the quantum (charge) Hall effect and the quantum spin Hall effect. In addition, it reconciles the apparent conflict between the stability of bulk topological order and the instability of gapless edge states in systems with open boundaries (as known happening in the spin Hall case). The consequences of time reversal invariance for bulk topological order and edge state dynamics are further studied in the present framework.

description: A classical $E_{d(d)}$-invariant Hamiltonian formulation of world-volume theories of half-BPS p-branes in type IIb and eleven-dimensional supergravity is proposed, extending known results to $d \leq 6$. It consists of a Hamiltonian, characterised by a generalised metric, and a current algebra constructed s.t. it reproduces the $E_{d(d)}$ generalised Lie derivative. $E_{d(d)}$-covariance necessitates the introduction of so-called charges, specifying the type of p-brane and the choice of section. For p>2, currents of p-branes are generically non-geometric due to the imposition of U-duality, e.g. the M5-currents contain coordinates associated to the M2-momentum. A derivation of the $E_{d(d)}$-invariant current algebra from a canonical Poisson structure is in general not possible. At most, one can derive a current algebra associated to para-Hermitian exceptional geometry. The membrane in the SL(5)-theory is studied in detail. It is shown that in a generalised frame the current algebra is twisted by the generalised fluxes. As a consistency check, the double dimensional reduction from membranes in M-theory to strings in type IIa string theory is performed. Many features generalise to p-branes in SL(p+3) generalised geometries that form building blocks for the $E_{d(d)}$-invariant currents.

description: Prominence threads are dense and cold structures lying on curved magnetic fields that can be suspended in the solar atmosphere against gravity. The gravitational stability of threads, in the absence of non-ideal effects, is comprehensively investigated in the present work by means of an elementary but effective model. Based on purely hydrodynamic equations in one spatial dimension and applying line-tying conditions at the footpoints of the magnetic field lines, we derive analytical expressions for the different feasible equilibria and the corresponding frequencies of oscillation. We find that the system allows for stable and unstable equilibrium solutions subject to the initial position of the thread, its density contrast and length, and the total length of the magnetic field lines. The transition between the two types of solutions is produced at specific bifurcation points that have been determined analytically in some particular cases. When the thread is initially at the top of the concave magnetic field, that is at the apex, we find a supercritical pitchfork bifurcation, while for a shifted initial thread position with respect to this point the symmetry is broken and the system is characterised by an S-shaped bifurcation. The plain results presented in this paper shed new light on the behaviour of threads in curved magnetic fields under the presence of gravity and help to interpret more complex numerical magnetohydrodynamics (MHD) simulations about similar structures.

description: Remnant accretion disks formed in compact object mergers are an important ingredient in the understanding of electromagnetic afterglows of multi-messenger gravitational-wave events. Due to magnetically and neutrino driven winds, a significant fraction of the disk mass will eventually become unbound and undergo r-process nucleosynthesis. While this process has been studied in some detail, previous studies have typically used approximate initial conditions for the accretion disks, or started from purely hydrodynamical simulations. In this work, we analyse the properties of accretion disks formed from near equal-mass black hole-neutron star mergers simulated in general-relativistic magnetohydrodynamics in dynamical spacetimes with an accurate microphysical description. The post-merger systems were evolved until $120\, {\rm ms}$ for different finite-temperature equations of state and black-hole spins. We present a detailed analysis of the fluid properties and of the magnetic-field topology. In particular, we provide analytic fits of the magnetic-field strength and specific entropy as a function of the rest-mass density, which can be used for the construction of equilibrium disk models. Finally, we evolve one of the systems for a total of $350\, \rm ms$ after merger and study the prospect for eventual jet launching. While our simulations do not reach this stage, we find clear evidence of continued funnel magnetization and clearing, a prerequisite for any jet-launching mechanism.

description: The Cushitic and Bantu language families are unrelated but to some extent similar in their morphology. Both verbal systems are characterised by complex affixation and both noun systems show interconnectedness of gender and number. The two families have been in contact in several points in time and space in East Africa and in many different sociolinguistic situations. The outcomes of language contact are often linked to variations in language dominance in the sociolinguistic settings but not so often based on empirical observation (Thomason & Kaufman 1988, Van Coetsem 2000, Winford 2002). In my talk I present an encyclopaedia of Cushitic-Bantu language contact situations, their outcomes and their sociolinguistic profile in order examine the proposed correlations critically. These situations range from partial language shift and mixed language creation to lexical borrowing linked to modernity. (Mous 2003, Mous & Qorro 2009; Kiessling e.a. 2008, Petrollino & Mous 2010).

description: Debris disks are characterized by the dusty, gas-depleted environment bearing non-primordial dust grains which are constantly generated by continuous collisions between planetesimals. High-contrast imaging in the near-infrared allows to measure the intensity distribution of the disk, which is dependent on the properties of these grains. My goal was
 to study the scattered light images of debris disks obtained by the SPHERE/VLT instrument installed in Chile. Post-processing techniques used to reduce the stellar contribution in images, such as angular differential imaging, involves self-subtraction of the disk image which must be corrected for to recover true photometry. For this, I use a model of radiative transfer, GRaTer, to model the morphology of the disk and so calculate the effect of self-subtraction. I studied the morphologies and the spatial distribution of the grains of three discs of debris, HD 32297, HD 141569 and HD 106906 and developed models reproducing the density and intensity distribution of these systems. By analyzing the average reflectances and the spectra obtained in modeling the grain size distribution, we see that these disks contain grains smaller than the blowout limit. This result can be attributed to the presence of gas and/or an effect of a collisional avalanche. This study puts a constraint on our current understanding of the evolution of grains towards the planets.

description: The reproducibility of published research has become an important topic in science policy. A number of large-scale replication projects have been conducted to gauge the overall reproducibility in specific academic fields. Here, we present an analysis of data from four studies which sought to forecast the outcomes of replication projects in the social and behavioural sciences, using human experts who participated in prediction markets and answered surveys. Because the number of findings replicated and predicted in each individual study was small, pooling the data offers an opportunity to evaluate hypotheses regarding the performance of prediction markets and surveys at a higher power. In total, peer beliefs were elicited for the replication outcomes of 103 published findings. We find there is information within the scientific community about the replicability of scientific findings, and that both surveys and prediction markets can be used to elicit and aggregate this information. Our results show prediction markets can determine the outcomes of direct replications with 73% accuracy (n=103). Both the prediction market prices and the average survey responses are correlated with outcomes (0.581 and 0.564 respectively, both p < .001). We also found a significant relationship between p-values of the original findings and replication outcomes. The dataset is made available through the R package pooledmaRket and can be used to further study community beliefs towards replications outcomes as elicited in the surveys and prediction markets.

Dielectric function of the QCD vacuum

description: It is shown that the inverse of the ghost form factor in the Hamilton approach to Yang-Mills theory in Coulomb gauge can be interpreted as the color dielectric function of the QCD vacuum. Furthermore the horizon condition to the ghost form factor implies that in the infrared the QCD vacuum is a perfect color diaelectric medium and therefore a dual superconductor. The dielectric function is explicitly calculated within a previously developed variational approach, using a specific ansatz for the vacuum wave functional.

Hysteretic ac loss of superconducting strips simultaneously exposed to ac transport current and phase-different ac magnetic field

Publisher: name: arXiv

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: A simple analytical expression is presented for hysteretic ac loss $Q$ of a superconducting strip simultaneously exposed to an ac transport current $I_0\cosωt$ and a phase-different ac magnetic field $H_0\cos(ωt+θ_0)$. On the basis of Bean's critical state model, we calculate $Q$ for small current amplitude $I_0\ll I_c$, for small magnetic field amplitude $H_0\ll I_c/2πa$, and for arbitrary phase difference $θ_0$, where $I_c$ is the critical current and $2a$ is the width of the strip. The resulting expression for $Q=Q(I_0,H_0,θ_0)$ is a simple biquadratic function of both $I_0$ and $H_0$, and $Q$ becomes maximum (minimum) when $θ_0=0$ or $π$ ($θ_0=π/2$).

description: The main purpose of the series of tests conducted at CESR in September was to verify the co-alignment of the five radiometer beams, and to adjust OSIRIS such that it also looks in the same direction as the radiometer. Note that results for OSIRIS are documented separately by Nick Lloyd and Doug Degenstein in "OSIRIS Beam Alignment Results from Toulouse September 2000". The measurements were not done in an anechoic environment, so we do not have accurate beam profiles of the radiometer down to the sidelobe levels,however, the main lobe is well measured. Another goal of the campaign was to measure the difference that is made in the beam profile when the telescope is heated up to a uniform temperature across the main reflector. The five channels of the radiometer are all very well co-aligned. OSIRIS is co-aligned with the beam direction of the radiometer. Heating the telescope did not produce any measurable difference, within the accuracy of the measurement setup.

description: INTEGRAL observatory is equipped with a collection of detectors monitoring the entire hard X-ray sky with over 80% duty cycle, and able to re-point to perform deep and sensitive hard X-ray observations of a large selected sky region. This makes INTEGRAL uniquely valuable in searches for elusive, unpredictable, and short-lived hard X-ray and gamma-ray counterparts of multimessenger transients. I will review the follow-up and dissemination strategy we have developed in these searches, which have in particular allowed to maximize scientific benefit of the first confident detection of the multi-messenger transient. These strategies continue to form the basis of the INTEGRAL follow-up activity of gravitational wave transients in the ongoing LIGO/Virgo O3 run. I will outline how semantically-annotated network of real-time services enables the complete workflow starting from parsing of the emerging scientific information in the machine-formatted alerts as well as human-made publications, then proceeding to the inference of new useful scientific conjectures, and concluding with publishing the provenance-enabled ontology-annotated results in outgoing alerts and linked-data online publications. The core of the platform is built around the mechanisms of workflow introspection and flexible interface-first modular development, allowing the researches to efficiently contribute to the constant improvement and operations of the platform by leveraging their core competencies in the collaborative research environment. The synergies and interoperability interfaces developed between different tiers of the platform and external collaborators enable its integration into the larger research and discovery process.
