description: We study conserved charges and thermodynamics of analytic rotating anti-de Sitter black holes with extended horizon topology -- also known as black strings -- in dynamical Chern-Simons modified gravity. The solution is supported by a scalar field with an axionic profile that depends linearly on the coordinate that spans the string. We compute conserved charges by making use of the renormalized boundary stress-energy tensor. Then, by adopting the Noether-Wald formalism, we compute the black string entropy and obtain its area law. Indeed, the reduced Euclidean Hamiltonian approach shows that these methods yield a consistent first law of thermodynamics. Additionally, we derive a Smarr formula using a radial conservation law associated to the scale invariance of the reduced action and obtain a Cardy formula for the black string. A first-order phase transition takes place at a critical temperature between the ground state and the black string, above which the black string is the thermodynamically favored configuration.

description: V1298 Tau is a young (20-30 Myr) solar-mass K star hosting four transiting exoplanets with sizes between 0.5 - 0.9 $R_J$. Given the system's youth, it provides a unique opportunity to understand the evolution of planetary radii at different separations in the same stellar environment. V1298 Tau was originally observed 6 years ago during K2 Campaign 4. Now, V1298 Tau has been re-observed during the extended mission of NASA's Transiting Exoplanet Survey Satellite (TESS). Here, we present new photometric observations of V1298 Tau from the 10-minute TESS Full-Frame Images. We use the TESS data to update the ephemerides for V1298 Tau bcde as well as compare newly observed radii to those measured from the K2 light curve, finding shallower transits for V1298 Tau bcd in the redder TESS bandpass at the $1-2σ$ level. We suspect the difference in radii is due to starspot-crossing events or contamination from nearby faint stars on the same pixels as V1298 Tau. Additionally, we catch a second transit of V1298 Tau e and present a new method for deriving the marginalized posterior probability of a planet's period from two transits observed years apart. We find the highest probability period for V1298 Tau e to be in a near 2:1 mean motion resonance with V1298 Tau b which, if confirmed, could make V1298 Tau bcde a 4 planet resonant chain. V1298 Tau is the target of several ongoing and future observations. These updated ephemerides will be crucial for scheduling future transit observations and interpreting future Doppler tomographic or transmission spectroscopy signals.

description: We give two approximation algorithms solving the Stochastic Boolean Function Evaluation (SBFE) problem for symmetric Boolean functions. The first is an $O(\log n)$-approximation algorithm, based on the submodular goal-value approach of Deshpande, Hellerstein and Kletenik. Our second algorithm, which is simple, is based on the algorithm solving the SBFE problem for $k$-of-$n$ functions, due to Salloum, Breuer, and Ben-Dov. It achieves a $(B-1)$ approximation factor, where $B$ is the number of blocks of 0's and 1's in the standard vector representation of the symmetric Boolean function. As part of the design of the first algorithm, we prove that the goal value of any symmetric Boolean function is less than $n(n+1)/2$. Finally, we give an example showing that for symmetric Boolean functions, minimum expected verification cost and minimum expected evaluation cost are not necessarily equal. This contrasts with a previous result, given by Das, Jafarpour, Orlitsky, Pan and Suresh, which showed that equality holds in the unit-cost case.
description: Preliminary versions of these results appeared on Arxiv in arXiv:1806.10660. That paper contains results for both arbitrary costs and unit costs. This paper considers only arbitrary costs. Updated January 2022 include journal information

description: This article examines the layer height h* on the strength characteristics of products manufactured by FDM printing. Strength characteristics are ensured during three-point bending tests. It is shown that the flexural strength depends on the layer height. Maximum flexural strength corresponds to a layer height of less than 65% of the extruder diameter. When the layer height is equal to the extruder diameter, the flexural strength drops by more than 2 times. An increase in the height of the printing layer leads to a sharp decrease in the flexural strength of materials up to a complete loss of strength capacity.
Critical spin dynamics of Heisenberg ferromagnets revisited

description: We calculate the dynamic structure factor $S (\boldsymbol{k},ω)$ in the paramagnetic regime of quantum Heisenberg ferromagnets for temperatures $T$ close to the critical temperature $T_c$ using our recently developed functional renormalization group approach to quantum spin systems. In $d=3$ dimensions we find that for small momenta $\boldsymbol{k}$ and frequencies $ω$ the dynamic structure factor assumes the scaling form $S(\boldsymbol{k},ω) = (τT G (\boldsymbol{k})/π)Φ(kξ, ωτ)$, where $ G (\boldsymbol{k})$ is the static spin-spin correlation function, $ξ$ is the correlation length, and the characteristic time-scale $τ$ is proportional to $ξ^{5/2}$. We explicitly calculate the dynamic scaling function $Φ(x,y)$ and find satisfactory agreement with neutron scattering experiments probing the critical spin dynamics in EuO and EuS. Precisely at the critical point where $ξ= \infty$ our result for the dynamic structure factor can be written as $S (\boldsymbol{k},ω) = (πω_k)^{-1} T_c G (\boldsymbol{k}) Ψ_c (ω/ω_k)$, where $ω_k \propto k^{5/2}$. We find that $Ψ_c(ν)$ vanishes as $ν^{-13/5}$ for large $ν$, and as $ν^{3/5}$ for small $ν$. While the large-frequency behavior of $Ψ_c (ν)$ is consistent with calculations based on mode-coupling theory and with perturbative renormalization group calculations to second order in $ε= 6-d$, our result for small frequencies disagrees with previous calculations. We argue that up until now neither experiments nor numerical simulations are sufficiently accurate to determine the low-frequency behavior of $Ψ_c (ν)$. We also calculate the low-temperature behavior of $S ( \boldsymbol{k},ω)$ in one- and two dimensional ferromagnets and find that it satisfies dynamic scaling with exponent $z=2$ and exhibits a pseudogap for small frequencies.

An exploratory study is undertaken of Indian companies providing complex process-oriented offshore IT services to their global customers. The analysis of the data related to the service provider side shows that developing dynamic capabilities is strongly driven by management and top-clients and results in the development of business processes and in establishing a strategic partnership with the client organization. Key findings are that information exchange and coordination are the key to a leveraging firm performance. © 2012 Taylor and Francis.
Natural recovery of genetic diversity by gene flow in reforested areas of the endemic Canary Island pine, Pinus canariensis

description: The endemic pine, Pinus canariensis, forms one of the main forest ecosystems in the Canary Islands. In this archipelago, pine forest is a mosaic of natural stands (remnants of past forest overexploitation) and artificial stands planted from the 1940's. The genetic makeup of the artificially regenerated forest is of some concern. The use of reproductive material with uncontrolled origin or from a reduced number of parental trees may produce stands ill adapted to local conditions or unable to adapt in response to environmental change. The genetic diversity within a transect of reforested stands connecting two natural forest fragments has been studied with nuclear and chloroplast microsatellites. Little genetic differentiation and similar levels of genetic diversity to the surrounding natural stands were found for nuclear markers. However, chloroplast microsatellites presented lower haplotype diversity in reforested stands, and this may be a consequence of the lower effective population size of the chloroplast genome, meaning chloroplast markers have a higher sensitivity to bottlenecks. Understory natural regeneration within the reforestation was also analysed to study gene flow from natural forest into artificial stands. Estimates of immigration rate into artificially regenerated forest were high (0.68-0.75), producing a significant increase of genetic diversity (both in chloroplast and nuclear microsatellites), which indicates the capacity for genetic recovery for P. canariensis reforestations surrounded by larger natural stands.
title: The devotion of collecting : ministers and the culture of print in the seventeenth-century Dutch Republic
Creators: name: Strickland, Forrest
Publisher: name: University of St Andrews
Year: 2020

description: This project is the first to analyze the known corpus of seventeenth-century Dutch ministerial library catalogues, and it asks how these sources inform our understanding of the religious and cultural climate during the Dutch Golden Age. Thousands of ministers served local congregations in the Netherlands. They considered books and pamphlets necessary for a godly life, and they were avid collectors of print. Over 240 catalogues of ministerial libraries survive from the seventeenth century, all of which have been examined for this study. Fifty-five have been transcribed in full. Libraries of a hundred or more books were not uncommon even amongst ministers in small rural townships. Some ministerial libraries reached to multiple thousands of books. Their calling demanded that they pursue greater understanding of the Bible, and they used their books in the pursuit of truth. The ideal minister was one who was diligent in private study as an act of service to the church and the nation. How did Protestant Dutch ministers use print in their efforts to bring the Republic into greater conformity with the biblical ideal? Ministers were central political and cultural figures in their communities, and they turned to books and print for the fulfillment of their pastoral charge. Knowledge of the books these ministers read sheds light on the history of the Netherlands, because it indicates the expectations placed upon them by their congregations and by their colleagues. Professors of theology, regional synods and even local congregations expected their ministers would continue to grow in knowledge and wisdom through the acquisition of books, and ministers in turn took the information they gathered from their libraries and sought to encourage greater godliness in all who would listen to their sermons or read their own printed texts. Protestant ministers worked under two primary assumptions: that Scripture was the final authority of faith and life, and that the Christian faith was an all-encompassing worldview. These assumptions induced many ministers to read books of nearly every variety, from those with whom they agreed and disagreed, and on all manner of topics. Because of their understanding that print was a powerful tool in the life of the godly, ministers devoted precious time and money to acquiring and writing books. They built libraries and they wrote books to fulfill their divine calling to guard the faith as it was entrusted to them and to encourage others in sound doctrine.

description: Worldwide, the palm oil industry has a track record of devastating impacts on women, their communities and the environment. Systematic human rights violations, persecution of human rights defenders, and the loss of forests and biodiversity are threatening the way of life and wellbeing of people displaced by and living around palm oil plantations. These violations impact entire families and communities. However, not enough attention has been paid to how new dynamics, caused by the palm oil industry, have deepened gender inequalities and how the destruction of the natural environment and rights violations by the palm oil industry have hit women hardest. Women are experiencing deteriorating living conditions, increased workloads and destroyed livelihoods. On top of that, women also face increased levels of gender-based and sexual violence while being at the forefront of defending their own and their communities’ rights.This report is a result of the collective work of ActionAid Netherlands and ActionAid Guatemala based on research conducted by Profundo. The testimonies presented here were compiled from interviews with Guatemalan women and other members of indigenous communities affected by palm oil production destined for the Dutch market via the Port of Rotterdam. The interviews were conducted between 2018 and mid-2020.

description: We describe an implementation of compressible inviscid fluid solvers with block-structured adaptive mesh refinement on Graphics Processing Units using NVIDIA's CUDA. We show that a class of high resolution shock capturing schemes can be mapped naturally on this architecture. Using the method of lines approach with the second order total variation diminishing Runge-Kutta time integration scheme, piecewise linear reconstruction, and a Harten-Lax-van Leer Riemann solver, we achieve an overall speedup of approximately 10 times faster execution on one graphics card as compared to a single core on the host computer. We attain this speedup in uniform grid runs as well as in problems with deep AMR hierarchies. Our framework can readily be applied to more general systems of conservation laws and extended to higher order shock capturing schemes. This is shown directly by an implementation of a magneto-hydrodynamic solver and comparing its performance to the pure hydrodynamic case. Finally, we also combined our CUDA parallel scheme with MPI to make the code run on GPU clusters. Close to ideal speedup is observed on up to four GPUs.

description: We consider a higher-derivative generalization of disformal transformations in $D$-dimensional spacetime and clarify the conditions under which they form a group with respect to the matrix product and the functional composition. These conditions allow us to systematically construct the inverse transformation in a fully covariant manner. Applying the invertible generalized disformal transformation to known ghost-free scalar-tensor theories, we obtain a novel class of ghost-free scalar-tensor theories, whose action contains the third- or higher-order derivatives of the scalar field as well as nontrivial higher-order derivative couplings to the curvature tensor.

description: In this paper we develop an analogue of Hamilton-Jacobi theory for the time-evolution operator of a quantum many-particle system. The theory offers a useful approach to develop approximations to the time-evolution operator, and also provides a unified framework and starting point for many well-known approximations to the time-evolution operator. In the important special case of periodically driven systems at stroboscopic times, we find relatively simple equations for the coupling constants of the Floquet Hamiltonian, where a straightforward truncation of the couplings leads to a powerful class of approximations. Using our theory, we construct a flow chart that illustrates the connection between various common approximations, which also highlights some missing connections and associated approximation schemes. These missing connections turn out to imply an analytically accessible approximation that is the "inverse" of a rotating frame approximation and thus has a range of validity complementary to it. We numerically test the various methods on the one-dimensional Ising model to confirm the ranges of validity that one would expect from the approximations used. The theory provides a map of the relations between the growing number of approximations for the time-evolution operator. We describe these relations in a table showing the limitations and advantages of many common approximations, as well as the new approximations introduced in this paper.
Anisotropy and quench dynamics of quasiholes in fractional quantum Hall liquids

description: We present a microscopic study of quasiholes in bosonic fractional quantum Hall (FQH) liquids at filling factor $ν=1/2$ in the lowest Landau level with anisotropic band mass tensors. We use the spatial density profile to characterize the shape of a quasihole and analyze its anisotropy. We then compare the quasihole's anisotropy with the intrinsic geometric metric of the system that is extracted from the maximal overlap between the numerically obtained quasihole ground state and a set of model wave functions of anisotropic quasiholes. For a static system, we find that the quasihole's anisotropy, similar to the intrinsic metric, grows with the anisotropy of the band mass tensor. When the quasihole develops well, we observe a correspondence between the anisotropy of the quasihole and the intrinsic metric of the underlying anisotropic FQH state. We also drive the system out of equilibrium by suddenly changing the band mass tensor. In this case, the shape of the quasihole evolves with time and shows similar dynamics with the intrinsic metric of the postquench state. The evolving frequency matches the energy of a spin-$2$ quadrupole degree of freedom in the system. Our results suggest that the density profile of a quasihole is a useful tool to estimate the intrinsic metric and capture the dynamics of an FQH system.

description: In higher dimensions, we explore planar hairy black hole configurations for a special subclass of the Horndeski theory, defined by two coupling functions depending on the kinetic term and enjoying shift symmetry and reflection symmetry. For this analysis, we derive a set of new solutions, given by time-dependent as well as time independent scalar field configurations. Additionally, we calculate their thermodynamic quantities by using Wald formalism, satisfying the First Law of Thermodynamics as well as a Smarr relation. Together with the above, the Wald procedure allows us to compute the shear viscosity, showing that for a suitable choice of the coupling functions the Kovtun-Son-Starinets bound is violated.

description: Little is known about how human resource practices contribute towards the competitiveness of people based-knowledge intensive organisations in developing countries. This paper examines the role of human resource practices in developing knowledge and learning capabilities for innovation in the Indian information technology services sector. The study draws from the experience of a sample of 11 of the largest information technology service providers (ITSPs) in India and is based on in-depth interviews. The main finding suggests that the talent management architecture of ITSPs that comprises human resource practices and the development of knowledge and learning capabilities is the main drivers of innovation. A conceptual framework showing the link between human resource practices, knowledge and learning capabilities and innovation of ITSPs is developed followed by the limitations of the study and avenues for future research. © 2013 Operational Research Society.

description: Large symmetry groups in quantum many-body systems could strongly enhance quantum fluctuations and thereby stabilize exotic quantum phases. Frustrated interactions were long known to have similar effects. Here we intertwine the large SU($N$) symmetry and the frustration in a $J_1$-$J_2$ SU($N$) Heisenberg model on a honeycomb lattice, where $J_1$ is the nearest-neighbor coupling and $J_2$ is the next-nearest-neighbor coupling. With a large-$N$ analysis, we obtain a rich phase diagram by varying both $N$ and the ratio $J_2/J_1$. The ground states include Dirac spin liquid, chiral spin liquid, valence cluster solids, flux ordered state, and stripe states. The physical properties of each phase are discussed.

description: Harmonic measurements of the longitudinal and transverse voltages in Bi-Sb/Co bilayers are presented. A large second harmonic voltage signal due to the ordinary Nernst effect is observed. In experiments where a magnetic field is rotated in the film plane, the ordinary Nernst effect shows the same angular dependence in the transverse voltage as the damping-like spin-orbit torque and in the longitudinal voltage as the unidirectional spin-Hall magneto-resistance respectively. Therefore, the ordinary Nernst effect can be a spurious signal in spin-orbit torque measurements, leading to an overestimation of the spin-Hall angle in topological insulators or semimetals.

description: In the evolutionary dynamics of a rock-paper-scissor (RPS) model, the effect of natural death plays a major role in determining the fate of the system. Coexistence, being an unstable fixed point of the model becomes very sensitive towards this parameter. In order to study the effect of mobility in such a system which has explicit dependence on mortality, we perform Monte Carlo simulation on a $2$-dimensional lattice having three cyclically-competing species. The spatio-temporal dynamics has been studied along with the two-site correlation function. Spatial distribution exhibits emergence of spiral patterns in the presence of diffusion. It reveals that the joint effect of death rate and diffusion (migration) leads to new coexistence and extinction scenarios.

description: We describe a novel twistorial construction of the asymptotic BMS symmetries at null infinity for asymptotically flat spacetimes. We define BMS twistors as spinor solutions to some set of components of the usual spacetime twistor equation restricted to null infinity. The space of BMS twistors is infinite-dimensional. We show that given two BMS twistors their symmetric tensor product can be used to generate (complex) vector fields which are the infinitesimal BMS symmetries of null infinity. In this sense BMS twistors are "square roots" of BMS symmetries. We also show that these BMS twistor equations can be written a pair of covariant spinor-valued equations which are completely determined by the intrinsic universal structure of null infinity.

Observation of communication behavior : the development of a research method for use in health care organizations
Creators: name: McGill, Mary Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: The objective of the Dissertation was to validate Sobert Bales' Interaction Process Analysis, and to adapt the method for analysis of staff and patient communications on a hospital ward. A comprehensive review of the group, organizational, and health care literature emphasized the lack of instruments for observing actual communication behavior in this organizational context. The study therefore focused on refining the research method, rather than on analyzing specific interaction patterns. A four-month field study was conducted in a 300-bed rehabilitation and extended care hospital in Southern Saskatchewan. Two wards were selected for study—an adult physical rehabilitation unit and a chronic setting. Subjects included all patients on the two wards, their families, and all staff involved in direct or indirect provision of care. A team of two non-participant observers coded dyadic communication behavior in-process on the wards. Hypotheses were tested regarding the relative importance of organizational position and context in explaining the variance of the interaction profiles. Support was also sought for the construct and face validity of the instrument. The Dissertation included details of the method and the training required to enable other researchers to employ the technique. Procedures for providing feedback to the subjects were also delineated, as active participation was considered crucial to the project's success. Partial support was obtained for two aspects of the construct validity of Interaction Process Analysis—the inclusiveness of the categorization and the independence of the category frequencies. Evidence of face validity was also given. A multivariate analysis of variance demonstrated that the position dyad was the most significant explanatory variable for the interaction profile, but the particular observer was also an important factor. The impact of organizational context varied with the dimension-Alternative explanations were given for the observer effect, and directions explored for future research. The study concluded that Bales' Interaction Process Analysis has a definite contribution to make to the study of behavior in health care organizations.

Effects of knowledge management on client-vendor relationship quality: the mediating role of global mindset

description: Purpose: This study argues that knowledge management (KM) by itself has only limited effects on client–vendor relationship (CVR) of global providers of highly customised services. Rather, it is the ability of top management to properly evaluate and utilise a vast array of complex knowledge which allows global firms to develop and maintain superior CVR. The paper tests the proposition that global mindset (GM) of top management mediates the effects of KM on CVR quality. Design/methodology/approach: The paper uses survey data from a sample of 68 international service providers (ISPs) in the information technology sector in India and partial least squares approach to structural equation modelling to test the hypotheses. Findings: The results show that both KM and GM have positive and statistically significant effects on the quality of CVRs. The results also confirm that the GM of top management has significant and substantive mediation effects on the relationship between KM and CVR quality. Research limitations/implications: The small size of the sample and the focus on ISPs in a single country constitute the main limitations of the study. Future research should ideally draw from a larger sample of ISPs from multiple countries and sectors in order to allow for greater generalisation of the findings. Practical implications: ISPs will benefit from developing the GM of their top management teams to enhance their CVRs. Originality/value: The paper provides new insights into how, in an international context, firms can transform their KM into superior CVR quality through the development of GM.

Neutrino emission from FRB-emitting magnetars

description: The detection of a bright radio burst (hereafter FRB 200428) in association with a hard X-ray burst from the Galactic magnetar SGR 1935+2154 suggests that magnetars can make FRBs. We study possible neutrino emission from FRB-emitting magnetars by developing a general theoretical framework. We consider three different sites for proton acceleration and neutrino emission, i.e. within the magnetosphere, in the current sheet region beyond the light cylinder, and in relativistic shocks far away from the magnetosphere. Different cooling processes for protons and pions are considered to calculate the neutrino emission suppression factor within each scenario. We find that the flux of the neutrino emission decreases with increasing radius from the magnetar due to the decrease of the target photon number density. We calculate the neutrino flux from FRB 200428 and its associated X-ray burst. The flux of the most optimistic case invoking magnetospheric proton acceleration is still $\sim4$ orders of magnitude below the IceCube sensitivity. We also estimate the diffuse neutrino background from all FRB-emitting magnetars in the universe. The total neutrino flux of magnetars during their FRB emission phases is a negligible fraction of observed diffuse emission even under the most optimistic magnetospheric scenario for neutrino emission. However, if one assumes that many more X-ray bursts without FRB associations can also produce neutrinos with similar mechanisms, magnetars can contribute up to $10^{-8} \ {\rm GeV \ s^{-1} \ sr^{-1} \ cm^{-2}}$ diffuse neutrino background flux in the GeV to multi-TeV range.

The cores were identified by the Balloon-borne Large Aperture Submillimeter Telescope (BLAST) during its 2005 survey of the Vulpecula region where 60 compact sources were detected simultaneously at 250, 350, and 500 micron. Four of these cores, with no IRAS-PSC or MSX counterparts, were observed with the NRAO Very Large Array (VLA) in the NH3(1,1) and (2,2) spectral lines. Our observations indicate that the four cores are cold (Tk

description: Dual-band infrared photodetectors (DBIPs) can discriminate desired signals from complex scenes and thus are highly expected for threat-warning, remote sensing, and astronomy applications. Conventional DBIPs with high-performances are, however, typically based on semiconductor thin films, but remain the challenges of complex spatial align, expensive growth and cooling requirement. Here, we report a tunable graphene plasmonic photodetector with dual-band infrared spectral selectivity driven by ferroelectric superdomain. The periodic ferroelectric polarization array with nanoscale ring shapes provides ultrahigh electrostatic field for spatially doping of monolayer graphene to desired patterns, and is further used to excite and confine intrinsic graphene plasmons. Our devices exhibit tunable resonance photoresponse in both two bands of 3.7-16.3 um and 15.1-52.1 um. The numerical calculations show that our devices own ultrahigh responsivities of 667-1080 A W-1 at room temperature in range of 5-50 um. Our devices make possible the applications of infrared imaging system and both stationary and motion state of objects detection. These investigations provide a novel approach for advanced infrared system construction by employing simple, low-cost, uncooling multispectral detectors array.
