description: A method to design a variable flux electric ma-chine using no rare earth materials is proposed. Starting from a synchronous reluctance machine’s rotor the electromagnetic and mechanical design goals are derived. To improve torque production radially magnetized low coercive field magnets are inserted in the rotor, allowing for a control of the rotor flux. The flux guidance is improved by removing the webs required for mechanical sturdiness, which is achieved instead by mold injecting fiber reinforced polymer into the flux barriers. On the basis of a large design of experiments and using Gaussian process regression models, the relation between the rotor design parameters and output torque as well as external fields in the magnets is investigated and an optimization is performed. The resulting machine design allows an operation with high torque without involuntary demagnetization. The potential of the polymer filled flux barriers is confirmed through structural mechanical analysis.

description: Privacy leakage events have been increasingly frequent recently. Your DOB, home address, workplace, household composition, race, shopping and movie preferences, and other sensitive information can be easily compromised without your awareness. Differential Privacy is a provable robustness approach to address those privacy issues. This thesis proposed three Differential Privacy methods to protect location data and census data. First method can protect your accurate home address while maintaining its South East position to the CBD. Second method can protect COVID infected patients’ home addresses and meanwhile preserve the distribution of those cases for epidemiological study. Third method protect census data.

description: Quantum gravitational effects in black hole spacetimes with a cosmological constant $Λ$ are considered. The effective quantum spacetimes for the black holes are constructed by taking into account the renormalization group improvement of classical solutions obtained in the framework of Unimodular Gravity (a theory which is identical to General Relativity at a classical level). This allows us to avoid the usual divergences associated with the presence of a running $Λ$. The horizons and causal structure of the improved black holes are discussed taking into account the current observational bounds for the cosmological constant. It is shown that the resulting effective quantum black hole spacetimes are always devoid of singularities.

description: On February 9, 2022, the USDA, Animal and Plant Health Inspection Service (APHIS) confirmed highly pathogenic avian influenza (HPAI) in a commercial turkey flock in Indiana. HPAI spreads rapidly, is transmittable across different species of birds, and is often lethal to infected birds. Since 2000, outbreaks of HPAI in the United States occurred in 2004 and again in 2014–15. More animals were lost in the 2014–15 outbreak than in any other infectious animal disease event in U.S. history. These events affected poultry commerce on a global scale, decimating international demand for U.S. poultry products and reducing incomes of affected U.S. producers as well as producers whose flocks did not contract HPAI. Government efforts to mitigate the disease were effective but costly.

description: Silage is a fermented feed in a silo pit and used fed to animal throughout the year. There are 4 phases (aerobic, anaerobic, stable, and feed-out) for silage. The most critical phases to manage to minimize nutritive losses are when the silage is going from an aerobic to an anaerobic environment and at feed-out. The first important step in achieving silage of high nutritive value is to harvest at the proper maturity and moisture level. Alfalfa should be harvested between mid-bud and one-tenth bloom, and corn should be harvested between one-half and two-thirds milk-line. The type of silo is (pile, bunker, bag, or upright) used for silage production. The

description: The supernova remnant Kes 73 and/or the magnetar 1E 1841-045 at its center can deposit a large amount of energy to the surroundings and is potentially responsible for particle acceleration. Using the data taken with the Fermi Large Area Telescope (LAT), we confirmed the presence of an extended source whose centroid position is highly consistent with this magnetar/supernova-remnant pair. Its emission is intense from 100 MeV to $>$100 GeV. Its LAT spectrum can be decoupled into two components which are respectively governed by two different mechanisms. According to the young age of this system, the magnetar is seemingly a necessary and sufficient source for the downward-curved spectrum below 10 GeV, as the observed $$10 GeV spectrum and the TeV spectrum.

description: One of the most often used methods of summing divergent series in physics is the Borel-type summation with control parameters improving convergence, which are defined by some optimization conditions. The well known annoying problem in this procedure is the occurrence of multiple solutions for control parameters. We suggest a method for resolving this problem, based on the minimization of cost functional. Control parameters can be introduced by employing the Borel-Leroy or Mittag-Leffler transforms. Also, two novel transformations are proposed using fractional integrals and fractional derivatives. New cost functionals are advanced, based on lasso and ridge selection criteria, and their performance is studied for a number of models. The developed method is shown to provide good accuracy for the calculated quantities.

description: Recently, transition metal dichalcogenides (TMDCs) semiconductors have been utilized for investigating quantum phenomena because of their unique band structures and novel electronic properties. In a quantum dot (QD), electrons are confined in all lateral dimensions, offering the possibility for detailed investigation and controlled manipulation of individual quantum systems. Beyond the definition of graphene QDs by opening an energy gap in nanoconstrictions, with the presence of a bandgap, gate-defined QDs can be achieved on TMDCs semiconductors. In this paper, we review the confinement and transport of QDs in TMDCs nanostructures. The fabrication techniques for demonstrating two-dimensional (2D) materials nanostructures such as field-effect transistors and QDs, mainly based on e-beam lithography and transfer assembly techniques are discussed. Subsequently, we focus on transport through TMDCs nanostructures and QDs. With steady improvement in nanoscale materials characterization and using graphene as a springboard, 2D materials offer a platform that allows creation of heterostructure QDs integrated with a variety of crystals, each of which has entirely unique physical properties.

description: There are large numbers of published (and unpublished) archaeological sites and monuments in South Asia, but much of the available documentation is not available in a digital format, and paper publication remains the default. Information about archaeological heritage varies in detail, and there is considerable variation in how archaeological sites are documented. This paper explores the work and challenges of the Mapping Archaeological Heritage in South Asia (MAHSA) project in digitising, modelling, re-interpreting, linking, and re-using non-digital archaeological data into a structured and standardised digital format using a common and unique controlled vocabulary, so that it may become findable, accessible, interoperable, and reusable data. Working with partners in South Asia, the MAHSA project is compiling existing and published data (from published documents, reports, and surveys) to be published in an Open Access database (Arches platform), which can be used for research and preservation. New and previously undocumented sites identified through the analysis of historic maps, remote sensing, automated site detection methods, and field documentation will also follow the same data standards and recording methodology. Retaining context while delivering ‘cleaned’ usable data is a key challenge to this type of data modelling, and the meanings of the original source and context are inevitably subject to re-interpretation during this process. The project is working collaboratively between South Asian and international stakeholders, each bringing their own expectations of data use, management, and accessibility, in addition to navigating the post-colonial space in which the project operates. To ensure usability, different use cases scenarios have been identified and are being developed with collaborators and database end-users. We argue that through linking archaeological data to their original sources and following best practices in modelling techniques, we can remain faithful to the original context while incorporating any change and enhancements where data needs to be verified and updated.

description: Sedimentation velocity analytical ultracentrifugation with fluorescence detection has emerged as a powerful method for the study of interacting systems of macromolecules. It combines picomolar sensitivity with high hydrodynamic resolution, and can be carried out with photoswitchable fluorophores for multi-component discrimination, to determine the stoichiometry, affinity, and shape of macromolecular complexes with dissociation equilibrium constants from picomolar to micromolar. A popular approach for data interpretation is the determination of the binding affinity by isotherms of weight-average sedimentation coefficients, sw. A prevailing dogma in sedimentation analysis is that the weight-average sedimentation coefficient from the transport method corresponds to the signal- and population-weighted average of all species. We show that this does not always hold true for systems that exhibit significant signal changes with complex formation - properties that may be readily encountered in practice, e.g., from a change in fluorescence quantum yield. Coupled transport in the reaction boundary of rapidly reversible systems can make significant contributions to the observed migration in a way that cannot be accounted for in the standard population-based average. Effective particle theory provides a simple physical picture for the reaction-coupled migration process. On this basis we develop a more general binding model that converges to the well-known form of sw with constant signals, but can account simultaneously for hydrodynamic co-transport in the presence of changes in fluorescence quantum yield. We believe this will be useful when studying interacting systems exhibiting fluorescence quenching, enhancement or Forster resonance energy transfer with transport methods.

description: We present a theoretical study of the electronic transport through Pt nanocontacts. We show that the analysis of the tunnelling regime requires a very careful treatment of the technical details. For instance, an insufficient size of the system can cause unphysical charge oscillations to arise along the transport direction; moreover, the use of an inappropriate basis set can deviate the distance dependence of the conductance from the expected exponential trend. While the conductance decay can be either corrected by employing ghost atoms or a large-cutoff-radius basis set, the same does not apply to the corrugation, for which only the second option is recommended. Interestingly, these details were not found to have a remarkable impact in the contact regime. These findings are important for theoretical studies of distance-dependent phenomena in scanning-probe and break-junction experiments.

The quality of priority ratios estimation in relation to a selected prioritization procedure and consistency measure for a Pairwise Comparison Matrix

Year: 2017
Subjects: subject: Artificial Intelligence (cs.AI)

description: An overview of current debates and contemporary research devoted to the modeling of decision making processes and their facilitation directs attention to the Analytic Hierarchy Process (AHP). At the core of the AHP are various prioritization procedures (PPs) and consistency measures (CMs) for a Pairwise Comparison Matrix (PCM) which, in a sense, reflects preferences of decision makers. Certainly, when judgments about these preferences are perfectly consistent (cardinally transitive), all PPs coincide and the quality of the priority ratios (PRs) estimation is exemplary. However, human judgments are very rarely consistent, thus the quality of PRs estimation may significantly vary. The scale of these variations depends on the applied PP and utilized CM for a PCM. This is why it is important to find out which PPs and which CMs for a PCM lead directly to an improvement of the PRs estimation accuracy. The main goal of this research is realized through the properly designed, coded and executed seminal and sophisticated simulation algorithms in Wolfram Mathematica 8.0. These research results convince that the embedded in the AHP and commonly applied, both genuine PP and CM for PCM may significantly deteriorate the quality of PRs estimation; however, solutions proposed in this paper can significantly improve the methodology.

description: The Adam-Gibbs (AG) relation connects the dynamics of a glass-forming liquid to its the thermodynamics via. the configurational entropy, and is of fundamental importance in descriptions of glassy behaviour. The breakdown of the Stokes-Einstein (SEB) relation between the diffusion coefficient and the viscosity (or structural relaxation times) in glass formers raises the question as to which dynamical quantity the AG relation describes. By performing molecular dynamics simulations, we show that the AG relation is valid over the widest temperature range for the diffusion coefficient and not for the viscosity or relaxation times. Studying relaxation times defined at a given wavelength, we find that SEB and the deviation from the AG relation occur below a temperature at which the correlation length of dynamical heterogeneity equals the wavelength probed.

We also obtain that ${\cal B}(Λ_b\to Λω)=(2.30\pm0.10)\times 10^{-6}$, ${\cal B}(Ξ_b^-\toΞ^- ϕ,Ξ^- ω)\simeq {\cal B}(Ξ_b^0\toΞ^0 ϕ,Ξ^0 ω)=(5.35\pm0.41,3.65\pm0.16)\times 10^{-6}$ and ${\cal B}(Ξ^-_b\toΞ^{-} η^{(\prime)})\simeq {\cal B}(Ξ^0_b\to Ξ^0 η^{(\prime)})=(2.51^{+0.70}_{-0.46},2.99^{+1.16}_{-0.57})\times 10^{-6}$. For the CP violating asymmetries, we show that ${\cal A}_{CP}(Λ_b\to p K^{*-})={\cal A}_{CP}(Ξ_b^-\to Σ^0(Λ)K^{*-})={\cal A}_{CP}(Ξ_b^0\to Σ^+K^{*-})=(19.7\pm 1.4)\%$. Similar to the charmless two-body $Λ_b$ decays, the $Ξ_b$ decays are accessible to the LHCb detector.

Thermodynamics of extremal rotating thin shells in an extremal BTZ spacetime and the extremal black hole entropy

description: In a (2+1)-dimensional spacetime with a negative cosmological constant, the thermodynamics and the entropy of an extremal rotating thin shell, i.e., an extremal rotating ring, are investigated. The outer and inner regions are taken to be the Bañados-Teitelbom-Zanelli (BTZ) spacetime and the vacuum ground state anti-de Sitter (AdS) spacetime, respectively. By applying the first law of thermodynamics to the extremal shell one shows that its entropy is an arbitrary function of the gravitational area $A_+$ alone, $S=S(A_+)$. When the shell approaches its own gravitational radius $r_+$ and turns into an extremal rotating BTZ black hole, it is found that the entropy of the spacetime remains such a function of $A_+$. It is thus vindicated, that extremal black holes, here extremal BTZ black holes, have different properties from the corresponding nonextremal black holes, which have the Bekenstein-Hawking entropy $S(A_+)= \frac{A_+}{4G}$, where $G$ is the gravitational constant. It is argued that for the extremal case $0\leq S(A_+)\leq \frac{A_+}{4G}$. Thus, rather than having just two entropies for extremal black holes, as previous results debated, 0 and $\frac{A_+}{4G}$, it is shown that extremal black holes may have a continuous range of entropies, limited by precisely those two entropies. Surely, the entropy that a particular extremal black hole picks must depend on past processes, notably on how it was formed. It is also found a remarkable relation between the third law of thermodynamics and the impossibility for a massive body to reach the velocity of light. In the procedure, it becomes clear that there are two distinct angular velocities for the shell, the mechanical and thermodynamic angular velocities. In passing, we clarify, for a static spacetime with a thermal shell, the meaning of the Tolman temperature formula at a generic radius and at the shell. (Abridged version).

Publisher: name: arXiv

Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics
subject: 90C15, 93E20

description: In this article, two methods for solving mean-field type optimal control problems are proposed and investigated. The two methods are iterative methods: at each iteration, a Hamilton-Jacobi-Bellman equation is solved, for a terminal condition obtained by linearizing the cost function. The terminal condition is updated by solving a Fokker-Planck equation. The first method can be seen as a gradient method and uses in an essential manner the convexity of the set of probability distributions. A convergence result for this method is provided. The second method incorporates a penalization term and provides feedback controls. We test the methods on four academic examples.

Interaction blockade for bosons in an asymmetric double well

description: The interaction blockade phenomenon isolates the motion of a single quantum particle within a multi-particle system, in particular for coherent oscillations in and out of a region affected by the blockade mechanism. For identical quantum particles with Bose statistics, the presence of the other particles is still felt by a bosonic stimulation factor $\sqrt{N}$ that speeds up the coherent oscillations, where $N$ is the number of bosons. Here we propose an experiment to observe this enhancement factor with a small number of bosonic atoms. The proposed protocol realises an asymmetric double well potential with multiple optical tweezer laser beams. The ability to adjust bias independently of the coherent coupling between the wells allows the potential to be loaded with different particle numbers while maintaining the resonance condition needed for coherent oscillations. Numerical simulations with up to three bosons in a realistic potential generated by three optical tweezers predict that the relevant avoided level crossing can be probed and the expected bosonic enhancement factor observed.

Tricritical behavior of nonequilibrium Ising spins in fluctuating environments

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We investigate the phase transitions in a coupled system of Ising spins and a fluctuating network. Each spin interacts with $q$ neighbors through links of the rewiring network. The Ising spins and the network are in thermal contact with the heat baths at temperatures $T_S$ and $T_L$, respectively, so that the whole system is driven out of equilibrium for $T_S \neq T_L$. The model is a generalization of the $q$-neighbor Ising model, which corresponds to the limiting case of $T_L=\infty$. Despite the mean field nature of the interaction, the $q$-neighbor Ising model was shown to display a discontinuous phase transition for $q\geq 4$. Setting up the rate equations for the magnetization and the energy density, we obtain the phase diagram in the $T_S$-$T_L$ parameter space. The phase diagram consists of a ferromagnetic phase and a paramagnetic phase. The two phases are separated by a continuous phase transition belonging to the mean field universality class or by a discontinuous phase transition with an intervening coexistence phase. The equilibrium system with $T_S=T_L$ falls into the former case while the $q$-neighbor Ising model falls into the latter case. At the tricritical point, the system exhibits the mean field tricritical behavior. Our model demonstrates a possibility that a continuous phase transition turns into a discontinuous transition by a nonequilibrium driving. Heat flow induced by the temperature difference between two heat baths is also studied.

description: We propose and study three confidence intervals (CIs) centered at an estimator that is intentionally biased to reduce mean squared error. The first CI simply uses an unbiased estimator's standard error; compared to centering at the unbiased estimator, this CI has higher coverage probability for confidence levels above 91.7%, even if the biased and unbiased estimators have equal mean squared error. The second CI trades some of this "excess" coverage for shorter length. The third CI is centered at a convex combination of the two estimators to further reduce length. Practically, these CIs apply broadly and are simple to compute.

description: We study dark matter production in scenarios where a scale invariant hidden sector interacts with the Standard Model degrees of freedom via a Higgs portal $λΦ^\daggerΦs^2$. If the hidden sector is very weakly coupled to the SM but exhibits strong interactions within its own particle species, the dark matter abundance may arise as a result of a dark freeze-out occurring in the hidden sector. Because of scale invariance, the free parameters in the hidden sector are determined and the dark matter candidate exhibits a 'WIMP miracle of the second kind'. Demonstrating the predictive power of scale invariance, we carry out thorough analysis of dark matter production in several benchmark scenarios where the hidden sector contains either a scalar, fermion (sterile neutrino), or vector dark matter, and discuss the observational consequences of these scenarios.

Experts in the Room: Role Conflict and Ambiguity in School Social Work around Chicago
Creators: name: Culbert, Nate
Publisher: name: University of Chicago
Year: 2022

description: The American public school system is facing a severe shortage of school social workers, such that the country employs only one of these professionals for every two elementary and middle schools. Because school social workers are less common on school grounds than faculty, administrators, or even counselors, educational institutions often lack organizational knowledge of their roles and responsibilities, making school social workers particularly prone to being misunderstood and overworked. This investigation draws upon organizational sociology theories and interview data to assess not only the degree to which school social workers are misunderstood throughout the school day, but also whether and how these individuals revise their colleagues’ inaccurate impressions of school social work. Nine school social workers from around the Chicago area and one education researcher participated in semi-structured interviews, lending perspectives which I analyzed via hand-coding. Their testimonies reveal that misunderstandings of school social work are highly dependent on the organizational context of a school – further, the school social workers interviewed described a variety of strategies for preventing or mitigating misunderstanding, such as politely correcting the offending party, passing out handbooks at the start of the school year, or disavowing their job description entirely. This study concludes with a series of policy recommendations designed to increase the awareness and understanding of school social work among school staff.

description: We explore the correlations between velocity and metallicity and the possible distinct chemical signatures of the velocity over-densities of the local Galactic neighbourhood. We use the large spectroscopic survey RAVE and the Geneva Copenhagen Survey. We compare the metallicity distribution of regions in the velocity plane ($v_R,v_ϕ$) with that of their symmetric counterparts ($-v_R,v_ϕ$). We expect similar metallicity distributions if there are no tracers of a sub-population (e.g., a dispersed cluster, accreted stars), if the disk of the Galaxy is axisymmetric, and if the orbital effects of the spiral arms and the bar are weak. We find that the metallicity-velocity space of the solar neighbourhood is highly patterned. A large fraction of the velocity plane shows differences in the metallicity distribution when comparing symmetric $v_R$ regions. The typical differences in the median metallicity are of $0.05$ dex with a statistical significance of at least $95\%$, and with values up to $0.6$ dex. For low azimuthal velocity $v_ϕ$, stars moving outwards in the Galaxy have on average higher metallicity than those moving inwards. These include stars in the Hercules and Hyades moving groups and other velocity branch-like structures. For higher $v_ϕ$, the stars moving inwards have higher metallicity than those moving outwards. The most likely interpretation of the metallicity asymmetry is that it is due to the orbital effects of the bar and the radial metallicity gradient of the disk. We present a simulation that supports this idea. We have also discovered a positive gradient in $v_ϕ$ with respect to metallicity at high metallicities, apart from the two known positive and negative gradients for the thick and thin disks, respectively.

description: The mausoleums of the emperors and of some members of the royal family of the Western Han Chinese dynasty, popularly known as Chinese pyramids, are a spectacular ensemble of tombs covered by a huge earth mounds, spread in the outskirts of modern Xian. Their inspiring model is the world famous tomb of the first emperor Qin, who reigned immediately before the Han, and in turn they were of inspiration for the much later mausoleums of the Song dynasty. Using satellite data we investigate here on cognitive aspects of the project of these two groups of monuments, with particular attention to the problem of their orientation and of their placement in the landscape; in particular, the presence of two distinct patterns of orientation, both connected with the polar region of the sky, arises. The analysis includes the cultural relationships of astronomy with orientation and topography, as well as a negative test of the possible influence of the Feng Shui tradition in the Western Han period. The special, much relevant case of the funerary landscape of emperor Wen of Han is also discussed.

$Λ_c$ Semileptonic Decays in a Quark Model

description: Hadronic form factors for semileptonic decay of the $Λ_c$ are calculated in a nonrelativistic quark model. The full quark model wave functions are employed to numerically calculate the form factors to all relevant orders in ($1/m_c$, $1/m_s$). The form factors obtained satisfy relationships expected from the heavy quark effective theory (HQET). The differential decay rates and branching fractions are calculated for transitions to the ground state and a number of excited states of $Λ$. The branching fraction of the semileptonic decay width to the total width of $Λ_c$ has been calculated and compared with other theoretical estimates and experimental results. The branching fractions for $Λ_c\toΛ^{*} l^{+}ν_l\toΣπl^{+}ν_l$ and $Λ_c\toΛ^{*} l^{+}ν_l\to N\bar{K} l^{+}ν_l$ are also calculated. Apart from decays to the ground state $Λ$(1115), it is found that decays through the $Λ(1405)$ provide a significant portion of the branching fraction $Λ_c\to X_s lν_l$. A new estimate for $f=B(Λ_c^{+}\toΛl^{+}ν_l)/B(Λ_c^{+}\to X_s l^{+}ν_l)$ is obtained.

description: Precision measurements of flavour observables provide powerful tests of many extensions of the Standard Model. This contribution covers a range of flavour measurements of $b\to s\ell^+\ell^-$ transitions, several of which are in tension with the Standard Model of particle physics, as well as their theoretical interpretation. The basics of the theoretical background are discussed before turning to the main question of the field: whether the anomalies can be explained by QCD effects or whether they may be indicators of effects beyond the Standard Model.

Front propagation and effect of memory in stochastic desertification models with an absorbing state

description: Desertification in dryland ecosystems is considered to be a major environmental threat that may lead to devastating consequences. The concern increases when the system admits two alternative steady states and the transition is abrupt and irreversible (catastrophic shift). However, recent studies show that the inherent stochasticity of the birth-death process, when superimposed on the presence of an absorbing state, may lead to a continuous (second order) transition even if the deterministic dynamics supports a catastrophic transition. Following these works we present here a numerical study of a one-dimensional stochastic desertification model, where the deterministic predictions are confronted with the observed dynamics. Our results suggest that a stochastic spatial system allows for a propagating front only when its active phase invades the inactive (desert) one. In the extinction phase one observes transient front propagation followed by a global collapse. In the presence of a seed bank the vegetation state is shown to be more robust against demographic stochasticity, but the transition in that case still belongs to the directed percolation equivalence class.
Thermogeometric description of the van der Waals like phase transition in AdS black holes

description: It is well known that interpreting the cosmological constant as the pressure, the AdS black holes behave as the van der Waals thermodynamic system. In this case, like a phase transition from vapor to liquid in a usual van der Waals system, black holes also changes phases about a critical point in the $P$-$V$ picture, where $P$ is the pressure and $V$ is the thermodynamic volume. Here, we give a geometrical description of this phase transition. Defining the relevant Legendre invariant thermogeometrics corresponding to the two criticality conditions, which determine the critical values of respective thermodynamical entities, we show that the critical point refers to the divergence of the Ricci scalars calculated from these metrics. The similar descriptions are also provided for the other two pictures of the van der Waals like phase transition: one is $T$-$S$ and the other one is $Y$-$X$ where $T$, $S$, $X$ and $Y$ are temperature, entropy, generalized force and generalized displacement; i.e. potential corresponding to external charge, respectively. The whole discussion is very general as no specific black hole metric is being used.

description: The S-band Polarisation All-Sky Survey (S-PASS) has observed the entire southern sky using the 64-metre Parkes radio telescope at 2.3GHz with an effective bandwidth of 184MHz. The surveyed sky area covers all declinations $δ\leq 0^\circ$. To analyse compact sources the survey data have been re-processed to produce a set of 107 Stokes $I$ maps with 10.75arcmin resolution and the large scale emission contribution filtered out. In this paper we use these Stokes $I$ images to create a total intensity southern-sky extragalactic source catalogue at 2.3GHz. The source catalogue contains 23,389 sources and covers a sky area of 16,600deg$^2$, excluding the Galactic plane for latitudes $|b|<10^\circ$. Approximately 8% of catalogued sources are resolved. S-PASS source positions are typically accurate to within 35arcsec. At a flux density of 225mJy the S-PASS source catalogue is more than 95% complete, and $\sim$94% of S-PASS sources brighter than 500mJy beam$^{-1}$ have a counterpart at lower frequencies.

description: Inspired by the recent "Complexity = Action" conjecture, we use the approach proposed by Lehner et al. to calculate the rate of the action of the WheelerDeWitt patch at late times for static uncharged and charged black holes in $f\left( R\right) $ gravity. Our results have the same expressions in terms of the mass, charge, and electrical potentials at the horizons of black holes as in Einstein's gravity. In the context of $f\left( R\right) $ gravity, the Lloyd bound is saturated for uncharged black holes but violated for charged black holes near extremality. For charged black holes far away from the ground states, the Lloyd bound is violated in four dimensions but satisfied in higher dimensions.
