description: Transitioning the care of a patient from a hospital to a skilled nursing facility (SNF) is critical and often risky. Poor care transitions can result in delays, medication mistakes, incomplete follow-up care, and adverse health outcomes. Ensuring a smooth and effective care transition is the goal for providers at both the hospital and SNF. At its foundation, successful care transitions rely on teamwork, relationship building, and communication among diverse groups of providers. Beth Israel Deaconess Medical Center (BIDMC) developed the ECHO-CT (Extension for Community Healthcare Outcomes-Care Transitions) program to improve transitions of care through structured, bi-directional communication between hospital-based and SNF-based providers. This paper describes key strategies for success in this model including: facilitating teamwork, eliminating hierarchy, and encouraging a bi-directional learning environment. We propose these as strategies that could be implemented in other organizations seeking to improve value during transitions of care.

description: In this paper, we consider a class of transportation problems which arises in sample surveys and other areas of statistics. The associated cost matrices of these transportation problems are of special structure. We observe that the optimality of North West corner solution holds for the general problem where cost component is replaced by a convex function. We revisit assignment problem and present a weighted version of K$\ddot{o}$nig-Egerv$\acute{a}$ry theorem and Hungarian method. The weighted Hungarian method proposed in the paper can be used for solving transportation problem.

description: Spherically symmetric random walks in arbitrary dimension $D$ can be described in terms of Gegenbauer (ultraspherical) polynomials. For example, Legendre polynomials can be used to represent the special case of two-dimensional spherically symmetric random walks. In general, there is a connection between orthogonal polynomials and semibounded one-dimensional random walks; such a random walk can be viewed as taking place on the set of integers $n$, $n=0,~1,~2,~\ldots$, that index the polynomials. This connection allows one to express random-walk probabilities as weighted inner products of the polynomials. The correspondence between polynomials and random walks is exploited here to construct and analyze spherically symmetric random walks in $D$-dimensional space, where $D$ is {\sl not} restricted to be an integer. The weighted inner-product representation is used to calculate exact closed-form spatial and temporal moments of the probability distribution associated with the random walk. The polynomial representation of spherically symmetric random walks is also used to calculate the two-point Green's function for a rotationally symmetric free scalar quantum field theory.

Evidence of a past disc-disc encounter: HV and DO Tau

description: Theory and observations suggest that star formation occurs hierarchically due to the fragmentation of giant molecular clouds. In this case we would expect substructure and enhanced stellar multiplicity in the primordial cluster. This substructure is expected to decay quickly in most environments, however historic stellar encounters might leave imprints in a protoplanetary disc (PPD) population. In a low density environment such as Taurus, tidal tails from violent star-disc or disc-disc encounters might be preserved over time-scales sufficient to be observed. In this work, we investigate the possibility that just such an event occured between HV Tau C (itself a component of a triple system) and DO Tau $\sim 0.1$ Myr ago, as evidenced by an apparent `bridge' structure evident in the $160$ $μ$m emission. By modelling the encounter using smoothed particle hydrodynamics (SPH) we reproduce the main features of the observed extended structure (`V'-shaped emission pointing west of HV Tau and a tail-like structure extending east of DO Tau). We suggest that HV Tau and DO Tau formed together in a quadruple system on a scale of $\sim 5000$ au ($0.025$ pc).

Analysis of the Lambda_b -> Lambda_c + l nu_l decay within a light-front constituent quark model

description: We present an investigation of the Isgur-Wise form factor relevant for the semileptonic decay Lambda_b -> Λ_c + l nu_l performed within a light-front constituent quark model. Adopting different baryon wave functions it is found that the Isgur-Wise form factor depends sensitively on the baryon structure. It is shown however that the shape of the Isgur-Wise function in the full recoil range relevant for the Lambda_b -> Λ_c + l nu_l decay can be effectively constrained using recent lattice QCD results at low recoil. Then, the Lambda_b -> Λ_c + l nu_l decay is investigated including both radiative effects and first-order power corrections in the inverse heavy-quark mass. Our final predictions for the exclusive semileptonic branching ratio, the longitudinal and transverse asymmetries, and the longitudinal to transverse decay ratio are: Br(Lambda_b -> Λ_c + l nu_l) = (6.3 +/- 1.6) % |V_bc / 0.040|**2 ~ tau(Lambda_b) / (1.24 ps), a_L = -0.945 +/- 0.014, a_T = -0.62 +/- 0.09 and R_L/T = 1.57 +/- 0.15, respectively. Moreover, both the longitudinal asymmetry and the (partially integrated) longitudinal to transverse decay ratio are found to be only marginally affected by the model dependence of the Isgur-Wise form factor as well as by first-order power corrections; therefore, their experimental determination might be a very interesting tool for testing the SM and for investigating possible New Physics.

Temperature dependence of butterfly effect in a classical many-body system

description: We study the chaotic dynamics in a classical many-body system of interacting spins on the kagome lattice. We characterise many-body chaos via the butterfly effect as captured by an appropriate out-of-time-ordered correlator. Due to the emergence of a spin liquid phase, the chaotic dynamics extends all the way to zero temperature. We thus determine the full temperature dependence of two complementary aspects of the butterfly effect: the Lyapunov exponent, $μ$, and the butterfly speed, $v_b$, and study their interrelations with usual measures of spin dynamics such as the spin-diffusion constant, $D$ and spin-autocorrelation time, $τ$. We find that they all exhibit power law behaviour at low temperature, consistent with scaling of the form $D\sim v_b^2/μ$ and $τ^{-1}\sim T$. The vanishing of $μ\sim T^{0.48}$ is parametrically slower than that of the corresponding quantum bound, $μ\sim T$, raising interesting questions regarding the semi-classical limit of such spin systems.

description: We examined the extent to which organizations' reputations encompass different types of stakeholders' perceptions, which may have differential effects on economic outcomes. Specifically, we propose that reputation consists of two dimensions: (1) stakeholders' perceptions of an organization as able to produce quality goods and (2) organizations' prominence in the minds of stakeholders. We empirically examined the distinct antecedents and consequences of these two dimensions of reputation in the context of U.S. business schools. Results suggest that prominence, which derives from the choices of influential third parties vis-à-vis an organization, contributes significantly to the price premium associated with having a favorable reputation.

Geometry of Higgs-branch superconformal primary bundles
Creators: name: Niarchos, Vasilis
Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: It is known that the two- and three-point functions of Higgs-branch superconformal primaries in 4d N=2 superconformal field theories obey non-renormalization theorems on N=2 superconformal manifolds. In this paper we prove a stronger statement, that the bundles of Higgs-branch superconformal primaries over N=2 superconformal manifolds are endowed with a flat connection, or equivalently that Higgs-branch superconformal primaries have vanishing Berry phases under N=2 exactly marginal deformations. This statement fits well with the proposed correspondence between the rigid structures of 2d chiral algebras and the sector of Schur operators in 4d N=2 theories. We also discuss the general interplay between non-renormalization theorems and the curvature of bundles of protected operators and provide a new simpler proof of the vanishing curvature of 1/2-BPS operators in 4d N=4 SYM theory that does not require the use of the 4d tt* equations.

description: The purpose of this qualitative study was to explore how team members experience and enact interprofessional teamwork in primary health care (PHC). Fifty-three participants (from eight teams), members of the Association of Family Health Teams of Ontario (AFHTO), were interviewed; interviews were audiotaped and transcribed verbatim. The data analyses used an iterative process with individual and team analysis. Findings revealed components that comprise the foundation and pillars of collaborative interprofessional teamwork in PHC. First, participants described a shared philosophsy of teamwork with six elements: values, vision, and mission; collaboration; communication; trust; respect and team members that ‘fit.’ Second, findings revealed three ‘pillars.’ The first pillar, leadership, included the elements of specific leadership attributes, such as leaders encouraging teamwork, mitigating conflict, and facilitating change. In the second pillar, participants described three elements of team building: formal and informal team building activities plus how these activities benefited both the team and patient care. The last pillar, optimizing scope of practice, included the elements of recognizing, appreciating, utilizing, and expanding team members’ scope of practice. While each component and their concomitant elements can be enacted individually, collectively applying all elements produces collaborative interprofessional teamwork in primary health care.

Based on a sample of 42 selected W+W- candidates containing an isolated hard photon, the W+W-gamma cross section, defined within phase-space cuts, is measured to be: sigma_WWgamma = 290 +/- 80 +/- 16 fb, consistent with the Standard Model expectation. Including the process e+e- -> nu nu gamma gamma, limits are derived on anomalous contributions to the Standard Model quartic vertices W+W- gamma gamma and W+W-Z gamma at 95% CL: -0.043 GeV^-2 < a_0/Lambda^2 < 0.043 GeV^-2 0.08 GeV^-2 < a_c/Lambda^2 < 0.13 GeV^-2 0.41 GeV^-2 < a_n/Lambda^2 < 0.37 GeV^-2.

description: We have recently witnessed tremendous success of Machine Learning (ML) in practical applications. Computer vision, speech recognition and language translation have all seen a near human level performance. We expect, in the near future, most business applications will have some form of ML. However, testing such applications is extremely challenging and would be very expensive if we follow today's methodologies. In this work, we present an articulation of the challenges in testing ML based applications. We then present our solution approach, based on the concept of Metamorphic Testing, which aims to identify implementation bugs in ML based image classifiers. We have developed metamorphic relations for an application based on Support Vector Machine and a Deep Learning based application. Empirical validation showed that our approach was able to catch 71% of the implementation bugs in the ML applications.

description: There has been a concerted effort to identify problems computable with quantum technology which are intractable with classical technology or require far fewer resources to compute. Recently, randomness processing in a Bernoulli factory has been identified as one such task. Here, we report two quantum photonic implementations of a Bernoulli factory, one utilising quantum coherence and single-qubit measurements and the other which uses quantum coherence and entangling measurements of two qubits. We show that the former consumes three orders of magnitude fewer resources than the best known classical method, while entanglement offers a further five-fold reduction. These concepts may provide a means for quantum enhanced-performance in the simulation of stochastic processes and sampling tasks.

description: A recently developed model of random walks on a $D$-dimensional hyperspherical lattice, where $D$ is {\sl not} restricted to integer values, is extended to include the possibility of creating and annihilating random walkers. Steady-state distributions of random walkers are obtained for all dimensions $D>0$ by solving a discrete eigenvalue problem. These distributions exhibit dimensionally dependent critical behavior as a function of the birth rate. This remarkably simple model exhibits a second-order phase transition with a nontrivial critical exponent for all dimensions $D>0$.

Ces expositions sont à l’origine de la dégradation des sols des aménagements d’irrigation à Koubri.   Ces phénomènes sont accentués par la conjugaison de plusieurs facteurs anthropiques mais aussi physiques.

L’observation direct et les télédétections ont servi de méthodologie. Au cours des 40 dernières années, on estime que l’érosion est responsable de la perte d’environ un tiers de la terre arable du globe et que cette perte continue d’augmenter à raison de plus de 10 millions d’hectares par an [4, p. 05].

description: We search for a Higgs particle with anomalous couplings in the e+e- -> H gamma, e+e- -> HZ and e+e- -> He+e- processes with the L3 detector at LEP. We explore the mass range 70GeV < m_H < 170GeV using 176pb^-1 of integrated luminosity at a center-of-mass energy of \sqrt{s} = 189GeV. The Higgs decays H -> bb, H -> gamma gamma and H -> Z gamma are considered in the analysis. No evidence for anomalous Higgs production is found. This is interpreted in terms of limits on the anomalous couplings d, d_B, Delta g_1^Z and Delta kappa_gamma. Limits on the Gamma(H -> gamma gamma) and Gamma(H -> Z gamma) partial widths in the explored Higgs mass range are also obtained.

description: We present Giant Metrewave Radio Telescope and Very Large Array observations of HI 21-cm absorption in ten z<=0.2 galaxy mergers that host strong radio sources. Seven of these mergers show strong absorption [with N(HI) ~10^{21-22} cm^{-2}, for spin temperature of 100 K and unit covering factor], leading to a total detection rate of 83 +/- 17% in low-z radio-loud galaxy mergers. This is ~3-4 times higher than that found for intrinsic HI 21-cm absorption in low-z radio sources in general. The fraction of intrinsic absorbers that are associated with mergers increases with increasing N(HI) threshold, i.e. ~40% and 100% of the absorbers with N(HI) >10^{21} cm^{-2} and >10^{22} cm^{-2} arise from mergers, respectively. The distribution of N(HI) among the mergers is significantly different from that found in isolated systems, with mergers giving rise to six times stronger absorption on average. The fraction of redshifted absorption components (with respect to the systemic velocity of the radio source obtained from optical emission lines) among mergers is found to be higher by two to three times compared to that found for non-interacting systems. Follow-up spatially-resolved multi-wavelength spectroscopy is essential to understand the exact connection between the presence of circumnuclear neutral gas and the AGN activity in these mergers.

The calculation is based on an extension of a finite-size technique previously employed to compute the running coupling in quenched QCD. As a by-product we obtain the $Λ$--parameter in this theory with completely controlled errors.

description: Orbiting a bright, nearby star the 55 Cnc system offers a rare opportunity to study a multiplanet system that has a wide range of planetary masses and orbital distances. Using two decades of photometry and spectroscopy data, we have measured the rotation of the host star and its solar-like magnetic cycle. Accounting for this cycle in our velocimetric analysis of the system allows us to revise the properties of the outermost giant planet and its four planetary companions. The innermost planet 55 Cnc e is an unusually close-in super-Earth, whose transits have allowed for detailed follow-up studies. Recent observations favor the presence of a substantial atmosphere yet its composition, and the nature of the planet, remain unknown. We combined our derived planet mass (Mp = 8.0+-0.3 Mearth) with refined measurement of its optical radius derived from HST/STIS observations (Rp = 1.88+-0.03 Rearth over 530-750nm) to revise the density of 55 Cnc e (rho = 6.7+-0.4 g cm-3). Based on these revised properties we have characterized possible interiors of 55 Cnc e using a generalized Bayesian model. We confirm that the planet is likely surrounded by a heavyweight atmosphere, contributing a few percents of the planet radius. While we cannot exclude the presence of a water layer underneath the atmosphere, this scenario is unlikely given the observations of the planet across the entire spectrum and its strong irradiation. Follow-up observations of the system in photometry and in spectroscopy over different time-scales are needed to further investigate the nature and origin of this iconic super-Earth.

description: We calculate the contributions to the rare B-decays, $B \to X_{s,d} ν\bar ν$, $B_{s,d} \to l^+l^- $ from the unit-charged technipions. Within the considered parameter space we find that: (a) the enhancements to the branching ratios in question can be as large as three orders of magnitude; (b) the ALEPH data of $B \to X_s ν\bar ν$ lead to strong mass bounds on $m_{p1}$ and $m_{p8}$: $m_{p8} \geq 620, 475 GeV$ for $F_Q=40GeV$ and $m_{p1}=100, 400 GeV$ respectively. (c) the CDF data of $B_s \to μ\bar μ$ lead to a relatively weak limit: $m_{p8} \geq 320 GeV$ for $F_Q=40GeV$ and $m_{p1}=200 GeV$.

description: The Juno mission is delivering spectacular data of Jupiter's magnetic field, while the gravity measurements finally allow constraining the depth of the winds observed at cloud level. However, to which degree the zonal winds contribute to the planet's dynamo action remains an open question. Here we explore numerical dynamo simulations that include an Jupiter-like electrical conductivity profile and successfully model the planet's large scale field. We concentrate on analyzing the dynamo action in the Steeply Decaying Conductivity Region (SDCR) where the high conductivity in the metallic Hydrogen region drops to the much lower values caused by ionization effects in the very outer envelope of the planet. Our simulations show that the dynamo action in the SDCR is strongly ruled by diffusive effects and therefore quasi stationary. The locally induced magnetic field is dominated by the horizontal toroidal field, while the locally induced currents flow mainly in the latitudinal direction. The simple dynamics can be exploited to yield estimates of surprisingly high quality for both the induced field and the electric currents in the SDCR. These could be potentially be exploited to predict the dynamo action of the zonal winds in Jupiter's SDCR but also in other planets.

description: We introduce a methodology for nonlinear inverse problems using a variational Bayesian approach where the unknown quantity is a spatial field. A structured Bayesian Gaussian process latent variable model is used both to construct a low-dimensional generative model of the sample-based stochastic prior as well as a surrogate for the forward evaluation. Its Bayesian formulation captures epistemic uncertainty introduced by the limited number of input and output examples, automatically selects an appropriate dimensionality for the learned latent representation of the data, and rigorously propagates the uncertainty of the data-driven dimensionality reduction of the stochastic space through the forward model surrogate. The structured Gaussian process model explicitly leverages spatial information for an informative generative prior to improve sample efficiency while achieving computational tractability through Kronecker product decompositions of the relevant kernel matrices. Importantly, the Bayesian inversion is carried out by solving a variational optimization problem, replacing traditional computationally-expensive Monte Carlo sampling. The methodology is demonstrated on an elliptic PDE and is shown to return well-calibrated posteriors and is tractable with latent spaces with over 100 dimensions.

description: A recently developed model of random walks on a $D$-dimensional hyperspherical lattice, where $D$ is {\sl not} restricted to integer values, is used to study polymer growth near a $D$-dimensional attractive hyperspherical boundary. The model determines the fraction $P(κ)$ of the polymer adsorbed on this boundary as a function of the attractive potential $κ$ for all values of $D$. The adsorption fraction $P(κ)$ exhibits a second-order phase transition with a nontrivial scaling coefficient for $04$. At $D=4$ there is a tricritical point with logarithmic scaling. This model reproduces earlier results for $D=1$ and $D=2$, where $P(κ)$ scales linearly and exponentially, respectively. A crossover transition that depends on the radius of the adsorbing boundary is found.

description: Numerous studies link DASH diet to reduced blood pressure, using animals’ models or epidemiology but its mechanism remains unclear. Urinary EVs offer non-invasive insights, potentially replacing tissue sampling. Transitioning to DASH diet alters kidney transporters in EVs: Aquaporin2 decreases, SLC12A3 (NCC) increases. This aligns with increased urine volume, reduced sodium reabsorption, and blood pressure decline due to high potassium, low sodium DASH diet. Our data highlight uEV protein changes as markers of kidney response to diet by analyzing a highly enriched urinary EV fraction.

description: Deep near-IR images from the VVV Survey were used to search for RR Lyrae type ab (RRab) stars within 100' from the Galactic Centre (GC). A sample of 960 RRab stars were discovered. We use the reddening-corrected magnitudes in order to isolate RRab belonging to the GC. The mean period for our RRab sample is $P=0.5446$ days, yielding a mean metallicity of $[Fe/H] = -1.30$ dex and a median distance from the Sun of $D=8.05$. We measure the RRab surface density using the less reddened region sampled here, finding $1000$ RRab/sq deg at a projected Galactocentric distance $R_G=1.6$ deg. This implies a large total mass ($M>10^9 M_\odot$) for the old and metal-poor population contained inside $R_G$. We measure accurate relative proper motions, from which we derive tangential velocity dispersions of $σV_l = 125.0$ and $σV_b = 124.1$ km/s along the Galactic longitude and latitude coordinates, respectively. The fact that these quantities are similar indicate that the bulk rotation of the RRab population is negligible, and implies that this population is supported by velocity dispersion. There are two main conclusions of this study. First, the population as a whole is no different from the outer bulge RRab, predominantly a metal-poor component that is shifted respect the Oosterhoff type I population defined by the globular clusters in the halo. Second, the RRab sample, as representative of the old and metal-poor stellar population in the region, have high velocity dispersions and zero rotation, suggesting a formation via dissipational collapse.

description: The GC–MS, and GC-FID runs were carried out on a two parallel GC-QP2010 and GC2010 instruments (Shimadzu, Kyoto, Japan). The GC column used was a 30 m × 0.25 mm i.d. × 0.25 μm df Supelcowax-10 column (MilliporeSigma). Helium was exploited as carrier gas, at a constant linear velocity of 30.0 cm/s which corresponding to an inlet pressure of 26.4 kPa for GC-MS and 97.4 kPa for GC-FID. The temperature program was the same in both analysis-type: 40°C at 3° C/min to 250°C, at 10°C/min to 280°C, held 10 min. GC-MS ion source temperature was set at 200°C; the interface temperature, 250°C. Scan range was set to m/z 40–360, with a scanning rate of 2000 amu/s. FFSNC 3.0 (Shimadzu) and NIST11 (Wiley) commercial libraries were used for identification, applying two filters, namely a spectrum similarity match over 85% and Linear Retention Index (LRI) (related to a C4-C24 FAMEs mixture) agreement in the ±15 range. The FID temperature was set at 280°C (sampling rate 40 ms) and gas flows were 40 mL/min for hydrogen and 400 mL/min for air, respectively. The data handling was supported by GCMSsolution ver.4.30 and GCsolution software (Shimadzu) for GC-MS and GC-FID analysis, respectively.

description: We present a search for electroweak production of single top quarks in the electron+jets and muon+jets decay channels. The measurements use ~90 pb^-1 of data from Run 1 of the Fermilab Tevatron collider, collected at 1.8 TeV with the DZero detector between 1992 and 1995. We use events that include a tagging muon, implying the presence of a b jet, to set an upper limit at the 95% confidence level on the cross section for the s-channel process ppbar->tb+X of 39 pb. The upper limit for the t-channel process ppbar->tqb+X is 58 pb.

description: INTRODUCTION: Pulmonary embolism is a leading cause of maternal mortality in the developed world. Ventilation-perfusion scintigraphy and Computer tomography cause ionizing radiation exposure. Gadolinium-enhanced magnetic resonance imaging is generally not indicated in pregnant patients. MRI using motion resistant techniques that do not use intravenous contrast material, such as balanced steady-state free precession may be a better approach in pregnant patients.

PURPOSE: To describe the preliminary findings of the use of SSFP for the evaluation of pregnant patients with suspected PE, and to compare with a young women population evaluated with postgadolinium 3D-gradient echo sequences for the same intention.

MATERIALS AND METHODS: Radiology database was searched for two groups of subjects who underwent chest MRI at 1.5T for suspected PE, between January, 2007 and June, 2010: pregnant patients with MRI including balanced SSFP (group A) and females younger than 45 years old including a T1-weighted postgadolinium 3D-GRE (group B) sequence. The final study population consisted of 21 subjects. Blind and independent evaluation of MR images was performed for image quality of the pulmonary arterial system, PE and other chest findings. Data was subject to statistical analysis.

RESULTS: Good image quality was observed in all central and lobar arteries on both groups and in 90% (group A) and at least 83.3% (group B) of the segmental arteries. There was no significant difference between groups A and B for image quality of central and lobar pulmonary arteries (p > 0.05).

CONCLUSION: SSFP can visualize central, lobar and segmental pulmonary arteries with sufficient image quality in pregnant patients, comparable to 3D-GRE.

description: Developing a workable beach cleaning tool to maintain the beaches clean is the aim of this project. Thebeaches may be thoroughly cleaned thanks to this gadget. It reduces the cost and manpower associated withcleaning up beaches. The objective is to build a useful, low-cost, and easily operated machine. A conveyorblade is used to collect the trash. Its parts consist of a moving belt that collects trash and places thecollected material within a box. This method helps to keep a beach clean and shields marine life from beingcontaminated by rubbish. The main tourist attractions in India's coastal areas are its beaches. These are themost contaminated places as well. The home needs a lot of time and effort to clean. The workers must putin human labour to pick up the trash. Trash that is tossed gets covered in sand, making it challenging toidentify the waste. The beaches' heat and humidity follow next, which makes it difficult for the personnelto collect the debris. We designed and produced a beach application that has the advantage of doing awaywith the difficulties.

description: Mosquito-transmitted diseases remain one of the most significant causes of mortality in the African continent, despite successes in controlling these diseases in other regions of the world. The disproportionate impact in areas of poverty suggests a need for control that is efficient and does not require complex technological control strategies. Focusing on the vectors of disease, the mosquito, there are many alternatives to synthetic, chemical pesticides that await discovery and development. Although some natural products have been described, there is still a need for continuing research that incorporates endogenous knowledge in the selection process for potential vector control candidates. Recent experiments using natural products are summarized. Ultimately, a paradigm shift in research that evaluates natural products in a comparative manner will help to produce new materials for effective and efficient control of vectors and thereby achieve sustainable reduction of the impacts from the diseases they carry.

description: We present the first broad-band X-ray study of the nuclei of 14 hard X-ray selected giant radio galaxies, based both on the literature and on the analysis of archival X-ray data from NuSTAR, XMM-Newton, Swift and INTEGRAL. The X-ray properties of the sources are consistent with an accretion-related X-ray emission, likely originating from an X-ray corona coupled to a radiatively efficient accretion flow. We find a correlation between the X-ray luminosity and the radio core luminosity, consistent with that expected for AGNs powered by efficient accretion. In most sources, the luminosity of the radio lobes and the estimated jet power are relatively low compared with the nuclear X-ray emission. This indicates that either the nucleus is more powerful than in the past, consistent with a restarting of the central engine, or that the giant lobes are dimmer due to expansion losses.
