description: The Decentralised Web (DW) has recently seen a renewed momentum, with a number of DW platforms like Mastodon, Peer-Tube, and Hubzilla gaining increasing traction. These offer alternatives to traditional social networks like Twitter, YouTube, and Facebook, by enabling the operation of web infrastructure and services without centralised ownership or control. Although their services differ greatly, modern DW platforms mostly rely on two key innovations: first, their open source software allows anybody to setup independent servers ("instances") that people can sign-up to and use within a local community; and second, they build on top of federation protocols so that instances can mesh together, in a peer-to-peer fashion, to offer a globally integrated platform. In this paper, we present a measurement-driven exploration of these two innovations, using a popular DW microblogging platform (Mastodon) as a case study. We focus on identifying key challenges that might disrupt continuing efforts to decentralise the web, and empirically highlight a number of properties that are creating natural pressures towards recentralisation. Finally, our measurements shed light on the behaviour of both administrators (i.e., people setting up instances) and regular users who sign-up to the platforms, also discussing a few techniques that may address some of the issues observed.

description: Background: Congestive heart failure (CHF) is a chronic progressive condition that affects the pumping power of your heart muscles. While often referred to simply as "heart failure," CHF specifically refers to the stage in which fluid builds up around the heart and causes it to pump inefficiently. An evaluation of screening for CHDs is very important, echocardiography is a non-invasive technique and Modern two-dimensional echocardiographic strategies offer a comprehensive way for evaluating virtually all types of CHD observed in both adults and children. Objective: The aim of this study is to find out the most common clinical presentation of congenital heart defects in children from 3 months to 16 years of age referred to echocardiography and confirm the presence of disease on echocardiography in Children Hospital Lahore. Methods: This is a descriptive and prospective Hospital-based study conducted in the pediatric cardiology unit outpatient department of CHILDREN HOSPITAL. This study included all the patients, irrespective of age, having confirmed the diagnosis of CHD on the basis of echocardiographic report. Results: In my study, 288 patients of clinically Diagnosed CHD referred to echocardiography were studied. Congenital heart defects were diagnosed more commonly between 3 months to 5 Years than other age groups. The reason for the higher incidence in the age group of 3 months to 5 years maybe that CHD becomes symptomatic at that age group. The commonest congenital heart defects with a single lesion in our study were Ventricular septal defect followed by Atrial septal defect, Tetralogy of Fallot, Patent ductus arteriosus Conclusions: We observed that Symptomatic patients mostly present in 3 months -5 years of age. At 0.16-5 year of age child presented with sweating, respiratory distress, syncope and tachypnea. While from 5-16 years, commonest symptoms were murmur, chest pain, respiratory distress, tachypnea. The most symptomatic lesion Congenital heart defects were Ventricle septal defect and Teratology of fallot Ventricle septal defect, Atrial septal defect Pulmonary stenosis. Transthoracic echocardiography is an important tool for confirmation of clinical presentations of CHD at different age group.

Hot Cosmic Qubits: Late-Time de Sitter Evolution and Critical Slowing Down

description: Temporal evolution of a comoving qubit coupled to a scalar field in de Sitter space is studied with an emphasis on reliable extraction of late-time behaviour. The phenomenon of critical slowing down is observed if the effective mass is chosen to be sufficiently close to zero, which narrows the window of parameter space in which the Markovian approximation is valid. The dynamics of the system in this case are solved in a more general setting by accounting for non-Markovian effects in the evolution of the qubit state. Self-interactions for the scalar field are also incorporated, and reveal a breakdown of late-time perturbative predictions due to the presence of secular growth.

description: In this article we solve the problem of maximizing the expected utility of future consumption and terminal wealth to determine the optimal pension or life-cycle fund strategy for a cohort of pension fund investors. The setup is strongly related to a DC pension plan where additionally (individual) consumption is taken into account. The consumption rate is subject to a time-varying minimum level and terminal wealth is subject to a terminal floor. Moreover, the preference between consumption and terminal wealth as well as the intertemporal coefficient of risk aversion are time-varying and therefore depend on the age of the considered pension cohort. The optimal consumption and investment policies are calculated in the case of a Black-Scholes financial market framework and hyperbolic absolute risk aversion (HARA) utility functions. We generalize Ye (2008) (2008 American Control Conference, 356-362) by adding an age-dependent coefficient of risk aversion and extend Steffensen (2011) (Journal of Economic Dynamics and Control, 35(5), 659-667), Hentschel (2016) (Doctoral dissertation, Ulm University) and Aase (2017) (Stochastics, 89(1), 115-141) by considering consumption in combination with terminal wealth and allowing for consumption and terminal wealth floors via an application of HARA utility functions. A case study on fitting several models to realistic, time-dependent life-cycle consumption and relative investment profiles shows that only our extended model with time-varying preference parameters provides sufficient flexibility for an adequate fit. This is of particular interest to life-cycle products for (private) pension investments or pension insurance in general.

description: Globally as well as in China, cities have contributed to most of the economic output and have accordingly given rise to most CO2 emissions. In particular, given unprecedented urbanization, cities will play an even greater role in shaping energy demand and CO2 emissions. Therefore, cities are the key to meeting its proposed carbon intensity target in 2020 and whatever climate commitments beyond 2020 that China may take. Given the paramount importance of cities, China is practicing low carbon city (LCC) development. Against this background, this paper first summarizes the general situation and main characteristics of China’s LCC development. The paper then identifies eight problems and challenges for China’s LCC development including the absence of sound carbon accounting systems, lack of low-carbon specific evaluation system, rare use of market-based instruments, insufficient government-enterprise interactions, excessive budget dependence on land concession, increasing difficulty in further carbon mitigation, inevitable emissions growth due to rising living standards, and coal-dominant energy structure in the foreseeable future. Since these challenges are not applied to one or few cities, but are to all cities across the country, finally, the paper discusses how governments, in particular the central government, should address these problems and challenges. Given that China has faced great difficulty ensuring that local governments act in accordance with centrally-directed policies, the paper in particular discusses ways to incentivize local governments not to focus on economic growth alone and to move away from a heavy reliance on land concession. The paper ends with emphasizing on putting a price on carbon a crucial step for China’s endeavor of harnessing the market forces to reduce its energy consumption and carbon emissions and genuinely transiting into a low-carbon economy.

description: Background: Recent advances in the understanding the pathophysiology of paranasal sinuses has revolutionized the surgical management of chronic and recurrent sinusitis. Coronal plane computerized tomographic (CT) scanning has dramatically improved the imaging of paranasal sinus anatomy as compared to sinus radiographs. Increasingly, subtle bony anatomic variations and mucosal abnormalities of this region are being detected. Data regarding the background prevalence of these findings are needed to determine their clinical relevance. Objective(s): To determine the frequency of computed tomography paranasal sinuses in the evaluation of sinusitis. Methodology: A cross-sectional study was conducted at Al-Razi Health Care, Lahore. From May 2018 to September 2019, data of 177 patients were collected through convenient sampling. Adults and children with acute maxillary sinusitis/ rhino sinusitis were included in the study. Data of patients with recent cold associated with irritating runny nose and headache along with congestion was collected from the patients. Statistical software for social sciences (SPSS version 22.0) is used for the analysis of data. Results: Out of 177 patients collected, 82 were females and 95 were males. History of running nose was collected. 51 out of 185 had running nose. 120 patients were presented with headache. 115 had the history of cough. 102 had shortness of breath and 107 had congestion. 59 patients were suffering from cold. The final result came out to be 106 sinusitis patients. Conclusion(s): Pathologies in the maxillary sinus are frequently found in CBCT imaging and have to be treated or followed-up accordingly. CBCT is applicable for diagnosis and treatment planning of clinically present sinusitis.

description: This article purports to trace the origin of money on the basis of factors in interpersonal relationships, affecting a sustainable development and public happiness, namely trust, reciprocity and the concept of we-rationality. Both the historical approach and the one based on traditional economic theory have been found inadequate mainly because they did not take into account these factors. The hypothesis expounded in the paper is that these values underlaid the beginning of economic activity. Initially economic activity was carried out within small human groups. In such groups interpersonal relations were not based on individual self-interest. As a matter of fact, there is historical evidence supporting the notion that the first exchanges were gift-giving and were made possible by trust and reciprocity as expounded by Polanyi (1957) and Sudgen (2000) among others. When the exchanges strengthened between elements of various groups all with the same values and moral characteristics the process toward the creation of money started, without any intrinsic value and the presence of any superior authority. In the paper it is also hypothesized that the creation of money is one of the basic factors in the progress of economic and social activity, together with ancient phenomena as language ad writing. Finally, the paper advocates that in future the economic activity be permeated by those moral values on which a sustainable development can be based. This will, in turn, increase the rate of economic and social growth.

description: Jet pull is an observable designed to probe colour flow between jets. Thus far, a particular projection of the pull vector, the pull angle, has been employed to distinguish colour flow between jets produced by a colour singlet or an octet decay. This is of particular importance in order to separate the decay of a Higgs boson to a pair of bottom quarks from the QCD background. However, the pull angle is not infra-red and collinear (IRC) safe. In this paper we introduce IRC safe projections of the pull vector that exhibit good sensitivity to colour flow, while maintaining calculability. We calculate these distributions to next-to-leading logarithmic accuracy, in the context of the hadronic decay of a Higgs boson, and compare these results to Monte Carlo simulations. This study allows us to define an IRC safe version of the pull angle in terms of asymmetry distributions. Furthermore, because of their sensitivity to wide-angle soft radiation, we anticipate that these asymmetries can play an important role in assessing subleading colour correlations and their modelling in general-purpose Monte Carlo parton showers.

description: We discuss repulsive Casimir forces between dielectric materials with non trivial magnetic susceptibility. It is shown that considerations based on naive pair-wise summation of Van der Waals and Casimir Polder forces may not only give an incorrect estimate of the magnitude of the total Casimir force, but even the wrong sign of the force when materials with high dielectric and magnetic response are involved. Indeed repulsive Casimir forces may be found in a large range of parameters, and we suggest that the effect may be realized in known materials. The phenomenon of repulsive Casimir forces may be of importance both for experimental study and for nanomachinery applications.

description: Sinonasal disease is one of the most common clinical head and neck pathologies. The major symptom of sinonasal polyps that help in diagnosis is nasal obstruction. On Computed Tomography, sinonasal polyposis appear as round soft tissue masses originating from the mucosal lining of sinonasal cavity. Objective of this research is to check the frequency of nasal and paranasal sinus polyps by Computed Tomography. By the use of cross sectional descriptive study and convenient sampling, 59 patients were included in the study of all age groups. Patients affected with trauma or any disease resembling sinonasal disease were excluded. 128 slice Philips machine was used to obtain coronal and axial views images. SPSS 20 was used for the statistical analysis, frequencies and percentages. Total patients selected for this research were 59 out of which sinonasal polyposis affected 15 people (25.4%) which were mostly males 55.9% at an average age of 35.5 years. The mostly occurring symptom of this disease is nasal obstruction along with mucosal thickening which was found to be present in 64.4% patients. Most commonly multiple sinuses (72.9%) were affected bilaterally (61%) and bone erosion (13.6%) was found to be a less frequent variable. Males were more affected than females. This study concluded that paranasal polyps occur frequently rather than Nasal polyps.

description: Pb(γ,γ′) photon scattering reactions were studied [1] with the nearly monochromatic, linearly polarized photon beams at the High Intensity γ-ray Source (HIγS) at the DFELL. Azimuthal scattering intensity asymmetries measured with respect to the polarization plane of the beam have been used for the first time to assign both the spin and parity quantum numbers of dipole excited states of ²⁰⁶,²⁰⁷,²⁰⁸Pb at excitation energies in the vicinity of 5.5 MeV. Evidence for dominant particle-core coupling is deduced from these results along with information on excitation energies and electromagnetic transition matrix elements.

description: Two-dimensional materials supporting deep-subwavelength plasmonic modes can also exhibit strong magneto-optical responses. Here, we theoretically investigate magnetoplasmons (MPs) in monolayer black phosphorus (BP) structures under moderate static magnetic fields. We consider three different structures, namely, a continuous BP monolayer, an edge formed by a semi-infinite sheet, and finally, a triangular wedge configuration. Each of these structures shows strongly anisotropic magneto-optical responses induced both by the external magnetic field and by the intrinsic anisotropy of the BP lattice. Starting from the magneto-optical conductivity of a single-layer of BP, we derive the dispersion relation of the MPs in the considered geometries, using a combination of analytical, semi-analytical, and numerical methods. We fully characterize the MP dispersions and the properties of the corresponding field distributions, and we show that these structures sustain strongly anisotropic subwavelength modes that are highly tunable. Our results demonstrate that MPs in monolayer BP, with its inherent lattice anisotropy as well as magnetically induced anisotropy, hold potential for tunable anisotropic materials operating below the diffraction limit, thereby paving the way for tailored nanophotonic devices at the nanoscale.

description: Nonlinear frequency conversion plays a crucial role in advancing the functionality of next-generation optical systems. Portable metrology references and quantum networks will demand highly efficient second-order nonlinear devices, and the intense nonlinear interactions of nanophotonic waveguides can be leveraged to meet these requirements. Here we demonstrate second harmonic generation (SHG) in GaAs-on-insulator waveguides with unprecedented efficiency of 40 W$^{-1}$ for a single-pass device. This result is achieved by minimizing the propagation loss and optimizing phase-matching. We investigate surface-state absorption and design the waveguide geometry for modal phase-matching with tolerance to fabrication variation. A 2.0 $μ$m pump is converted to a 1.0 $μ$m signal in a length of 2.9 mm with a wide signal bandwidth of 148 GHz. Tunable and efficient operation is demonstrated over a temperature range of 45 $^{\circ}$C with a slope of 0.24 nm/$^{\circ}$C. Wafer-bonding between GaAs and SiO$_2$ is optimized to minimize waveguide loss, and the devices are fabricated on 76 mm wafers with high uniformity. We expect this device to enable fully integrated self-referenced frequency combs and high-rate entangled photon pair generation.

We here introduce a newly discovered quantum gate, B, that can implement any arbitrary two-qubit quantum operation with minimal number of both two- and single-qubit gates. We show this by giving an analytic circuit that implements a generic nonlocal two-qubit operation from just two applications of the B gate. We also demonstrate that for the highly scalable Josephson junction charge qubits, the B gate is also more easily and quickly generated than the CNOT gate for physically feasible parameters.

description: Biofuels production has experienced rapid growth worldwide as one of several strategies to promote green energy economies. Indeed, climate change mitigation and energy security have been frequent rationales behind biofuel policies, but biofuels production could generate negative impacts, such as additional demand for feedstocks, and therefore for land on which to grow them, with a consequent increase in food commodity price. In this context, this paper examines the effect of biofuels and other economic and financial factors on daily returns of a group of commodity futures prices using Generalized Autoregressive Conditional Heteroskedasticity (GARCH) family models in univariate and multivariate settings. The results show that a complex of drivers are relevant in explaining commodity futures returns; more precisely, the Standard and Poor’s (S&P) 500 positively affects commodity markets, while the US/Euro exchange rate brings about a decline in commodity returns. It turns out, in addition, that energy market returns are significant in explaining commodity returns on a daily basis, while monetary liquidity does not. Finally, the GARCH model has shown that current variance is influenced more by its past values than by the previous day’s shocks, and there is high persistence, meaning that variance slowly decays and prompts a sluggish “revert to the mean.” The multivariate BEKK framework confirms the results of the univariate setting.

description: We relate to others in two important ways: we care about others, and we care about how we fare in comparison to others. In some contexts, these two forms of relatedness interact. Caring about others can conveniently be labeled altruism. Caring about how we fare in comparison with others who fare better than ourselves can conveniently be labeled relative deprivation. I provide examples of domains in which the incorporation of altruism and relative deprivation can point to novel perspectives and suggest rethinking, and possibly revising, long-held views. And I show that there are domains in which consideration of relative deprivation can substitute for the prevalence of altruism, and vice versa. I conclude that this is a fascinating sphere for research on economics and social behavior.

description: As an industry representing soft power, the coordinated development between sports industry and tourism plays an important role in promoting economic growth. Using the cointegration theory, we carry out empirical test of economic growth, the output value of sport and tourism income; using the coordination theory, we carry out the evaluation of the coordinated development between sports industry and tourism. It is found in the study that there is a long-term stable dynamic equilibrium relationship among economic growth, the output value of sport and tourism income. The sports industry and tourism in Henan Province have undergone six stages (imbalance—on the verge of imbalance—barely coordinated—primarily coordinated—moderately coordinated—well coordinated). In the process of coordinated development, sports industry significantly lags behind tourism, so it is necessary to strengthen the sports industry personnel's quality, and optimize the coordination between the sports industry and tourism, so as to promote economic development level.

Temperature dependence of the Stark shifts of Er$^{3+}$ transitions in Er$_2$O$_3$ thin film on Si (001)

description: Optical transitions of an Er$_2$O$_3$ film on a Si substrate grown by using a metal-organic chemical vapor deposition technique were investigated in a wide temperature (300 K $\sim$ 5 K) and spectral (500 nm and 850 nm) ranges. Numerous sharp transitions corresponding to the Er$^{3+}$ ionic levels were observed, which show Stark shifts induced by the crystal field. With decreasing temperature from 300 K to 5 K, all transition peaks exhibit spectral red-shift. We believe that such red-shift behavior is due to the change of the crystal field together with the change of strain field induced by the film and the substrate in varying temperature. An interesting result is the total amount of red-shifts between 300 K and 5 K. We obtain that the higher transition energy peaks show bigger red-shifts. This is very consistent to all transition peaks. This is because the dipole moments between the transition levels are different that lead to different amounts of Stark shifts.

description: We consider a model of the state evolution of relativistic vector bosons, which includes both the dynamical equations for the particle four-velocity and the equations for the polarization four-vector evolution in the field of a nonlinear plane gravitational wave. In addition to the gravitational minimal coupling, tidal forces linear in curvature tensor are suggested to drive the particle state evolution. The exact solutions of the evolutionary equations are obtained. Birefringence and tidal deviations from the geodesic motion are discussed.

description: We analyze in detail the fluctuations and correlations of the (spatial) Fourier modes of nano-scale single-layer islands on (111) fcc crystal surfaces. We analytically show that the Fourier modes of the fluctuations couple due to the anisotropy of the crystal, changing the power spectrum of the fluctuations, and that the actual eigenmodes of the fluctuations are the appropriate linear combinations of the Fourier modes. Using kinetic Monte Carlo simulations with bond-counting parameters that best match realistic energy barriers for hopping rates, we deduce absolute line tensions as a function of azimuthal orientation from the analyses of the fluctuation of each individual mode. The autocorrelation functions of these modes give the scaling of the correlation times with wavelength, providing us with the rate-limiting kinetics driving the fluctuations, here step-edge diffusion. The results for the energetic parameters are in reasonable agreement with available experimental data for Pb(111) surfaces, and we compare the correlation times of island-edge fluctuations to relaxation times of quenched Pb crystallites.

description: Toxoplasma gondii is a prevalent zoonotic pathogen infecting livestock as well as humans. The exceptional ability of this parasite to reproduce in several types of nucleated host cells necessitates a coordinated usage of endogenous and host-derived nutritional resources for membrane biogenesis. Phosphatidylethanolamine is the second most common glycerophospholipid in T. gondii, but how its requirement in the acutely-infectious fast-dividing tachyzoite stage is satisfied remains enigmatic. This work reveals that the parasite deploys de novo synthesis and salvage pathways to meet its demand for ester- and ether-linked PtdEtn. Auxin-mediated depletion of the phosphoethanolamine cytidylyltransferase (ECT) caused a lethal phenotype in tachyzoites due to impaired invasion and cell division, disclosing a vital role of the CDP-ethanolamine pathway during the lytic cycle. In accord, the inner membrane complex appeared disrupted concurrent with a decline in its length, parasite width and major phospholipids. Integrated lipidomics and isotope analyses of the TgECT mutant unveiled the endogenous synthesis of ester-PtdEtn, and salvage of ether-linked lipids from host cells. In brief, this study demonstrates how T. gondii operates various means to produce distinct forms of PtdEtn while featuring the therapeutic relevance of its de novo synthesis.

description: The level of globalization of several ASEAN countries has increased for decades. This increasing level of globalization shows that these countries are increasingly open in terms of economic, social and political aspects. It is widely debated the impact of this openness on developing countries. This paper aims to see the impact of economic, social and political openness on unemployment in several ASEAN countries. This study uses panel data from six countries in ASEAN from 2010-2015 with the KOF index. The study found that the increase of economic and social globalization has an impact on reducing unemployment in ASEAN, while the increase of political globalization could increase unemployment in ASEAN.

description: If the fundamental Planck scale is of order a TeV, as the case in some extra-dimensions scenarios, future hadron colliders such as the Large Hadron Collider will be black hole factories. The non-perturbative process of black hole formation and decay by Hawking evaporation gives rise to spectacular events with up to many dozens of relatively hard jets and leptons, with a characteristic ratio of hadronic to leptonic activity of roughly 5:1. The total transverse energy of such events is typically a sizeable fraction of the beam energy. Perturbative hard scattering processes at energies well above the Planck scale are cloaked behind a horizon, thus limiting the ability to probe short distances. The high energy black hole cross section grows with energy at a rate determined by the dimensionality and geometry of the extra dimensions. This dependence therefore probes the extra dimensions at distances larger than the Planck scale.

description: Strong coupling of quantum emitters with confined electromagnetic modes of nanophotonic structures may be used to change optical, chemical and transport properties of materials, with significant theoretical effort invested towards a better understanding of this phenomenon. However, a full theoretical description of both matter and light is an extremely challenging task. Typical theoretical approaches simplify the description of the photonic environment by describing it as a single or few modes. While this approximation is accurate in some cases, it breaks down strongly in complex environments, such as within plasmonic nanocavities, and the electromagnetic environment must be fully taken into account. This requires the quantum description of a continuum of bosonic modes, a problem that is computationally hard. We here investigate a compromise where the quantum character of light is taken into account at modest computational cost. To do so, we focus on a quantum emitter that interacts with an arbitrary photonic spectral density and employ the cumulant or cluster expansion method to the Heisenberg equations of motion up to first, second and third order. We benchmark the method by comparing with exact solutions for specific situations and show that it can accurately represent dynamics for many parameter ranges.
Discovery of an X-ray Quasar Wind Driving the Cold Gas Outflow in the Ultraluminous Infrared Galaxy IRAS F05189-2524

description: We present new XMM-Newton and NuSTAR observations of the galaxy merger IRAS F05189-2524 which is classified as an ultra-luminous infrared galaxy (ULIRG) and optical Seyfert 2 at $z$ = 0.0426. We test a variety of spectral models which yields a best-fit consisting of an absorbed power law with emission and absorption features in the Fe K band. Remarkably, we find evidence for a blueshifted Fe K absorption feature at $E$ = 7.8 keV (rest-frame) which implies an ultra-fast outflow (UFO) with $v_{\mathrm{out}} = 0.11\ \pm\ 0.01c$. We calculate that the UFO in IRAS F05189-2524 has a mass outflow rate of $\dot{M}_{\mathrm{out}}\ \gtrsim 1.0\ M_\odot$ yr$^{-1}$, a kinetic power of $\dot{E}_{\mathrm{K}} \gtrsim$ 8% $L_{\mathrm{AGN}}$, and a momentum rate (or force) of $\dot{P}_{\mathrm{out}}\ \gtrsim 1.4\ L_{\mathrm{AGN}}/c$. Comparing the energetics of the UFO to the observed multi-phase outflows at kiloparsec scales yields an efficiency factor of $f\sim0.05$ for an energy-driven outflow. Given the uncertainties, however, we cannot exclude the possibility of a momentum-driven outflow. Comparing IRAS F05189-2524 with nine other objects with observed UFOs and large-scale galactic outflows suggests that there is a range of efficiency factors for the coupling of the energetics of the nuclear and galaxy-scale outflows that likely depend on specific physical conditions in each object.
