description: Fungal diseases are significant dangers to the most significant grains whereupon humankind depends. Were there to be a significant pandemic that seriously decreased yields, its belongings would spread all through the globalized food framework. To investigate these repercussions, we utilize an incomplete harmony monetary model of the worldwide food framework to contemplate a speculative extreme yet brief plague that diminishes rice yields in the nations influenced by 80%. We demonstrated a progression of scourge situations of expanding seriousness, beginning with the illness in a solitary nation in southeast Asia and completion with the microbe present in the greater part of eastern Asia. The pandemic and resulting crop misfortunes prompted considerably expanded worldwide rice & wheat costs. In any case, as long as worldwide item exchange was unlimited and ready to react sufficiently quick, the impacts on singular calorie utilization were, to a huge part, alleviated. A portion of the more terrible impacts were anticipated to be experienced by helpless net-rice bringing in nations in sub-Saharan Africa, which were not influenced legitimately by the sickness however endured as a result of higher rice costs. We scrutinize the suppositions of our models and investigate political monetary weights to limit exchange now and again of emergency. We wrap up by contending for the significance of 'stress-testing' the flexibility of the worldwide food framework to trim sickness and different stuns.

description: This study investigates how a region’s labour productivity could be influenced by intangible factors such as social capital, government quality, cultural dimensions and religion - factors that have not received much attention in the previous literature. As another novelty, regional-level data (78 regions of 22 European countries) were analysed. In order to take into account the relationships between various factors of productivity, the structural equation modelling approach is used enabling to find out both direct and indirect effects. The results showed institutional trust and civic participation to be the most important for productivity. Individualism appeared to have a positive and masculinity and power distance a negative total effect on labour productivity.

description: We aim at characterizing the hot phase of the Circum-Galactic Medium in a large sample of galaxies. We stack X-ray events from the SRG/eROSITA eFEDS survey around central galaxies in the GAMA 9hr field to construct radially projected soft X-ray luminosity profiles as a function of their stellar mass and specific star formation rate. We consider samples of quiescent (star-forming) galaxies in the stellar mass range $2\times 10^{10}$ -- $10^{12}$ M$_\odot$ ($3\times 10^9$ -- $6\times10^{11}$ M$_\odot$). For quiescent galaxies, the X-ray profiles are clearly extended throughout the available mass range; however, the measured profile is likely biased high due to projection effects, as these galaxies tend to live in dense and hot environments. For the most massive star forming samples ($\geq10^{11}$ M$_\odot$), there is a hint of detection of extended emission. For star-forming galaxies with $< 10^{11}$ M$_\odot$ the X-ray stacked profiles are compatible with unresolved sources and consistent with the expected emission from faint Active Galactic Nuclei and X-ray binaries. We measure for the first time the mean relation between average X-ray luminosity and stellar mass separately for quiescent and star-forming galaxies. High-mass ($\geq 10^{11}$ M$_\odot$) star-forming or quiescent galaxies follow the expected scaling of virialized hot haloes, while lower mass star-forming galaxies show a less prominent luminosity and a weaker dependence on stellar mass, consistent with empirical models of the weak AGN population. When comparing our results with state-of-the art numerical simulations, we find an overall consistency on large ($>80$ kpc) scales at masses $\geq 10^{11}$ M$_\odot$, but disagreement on the small scales, where brighter than observed compact cores are predicted. Simulations also do not predict the clear differentiation that we observe between quiescent and star-forming galaxies.

description: We introduce the concept of regular quantum graphs and construct connected quantum graphs with discrete symmetries. The method is based on a decomposition of the quantum propagator in terms of permutation matrices which control the way incoming and outgoing channels at vertex scattering processes are connected. Symmetry properties of the quantum graph as well as its spectral statistics depend on the particular choice of permutation matrices, also called connectivity matrices, and can now be easily controlled. The method may find applications in the study of quantum random walks networks and may also prove to be useful in analysing universality in spectral statistics.

description: Quantum state targeting is a quantum game which results from combining traditional quantum state estimation with additional classical information. We consider a particular version of the game and show how it can be played with maximally entangled states. The optimal solution of the game is used to derive a Bell inequality for two entangled qutrits. We argue that the nice properties of the inequality are direct consequences of the method of construction.

description: The linkages between gender, crop choice and agricultural output must be explored if food security is to be ensured under changing climates. Using a rich nationally representative household panel dataset from Uganda, this paper addresses the topic empirically, bringing new evidence to a literature that has not yet fully examined the role of gender in responding to environmental shocks that increase agricultural production variability. A longitudinal analysis that endogenizes production portfolios and agricultural decision-maker gender in ascertaining productivity outcomes indicates parcel manager gender and crop diversity are distinguishing factors in the household food security function. Heterogeneity is explored in the context of diverse agro-ecological zones and differential access to factors of production.
Radio jets: properties, life and impact

description: Our view of the properties of extragalactic radio jets and the impact they have on the host galaxy has expanded in the recent years. This has been possible thanks to the data from new or upgraded radio telescopes. This review briefly summarises the current status of the field and describes some of the exciting recent results and the surprises they have brought. In particular, the physical properties of radio jets as function of their radio power will be discussed together with the advance made in understanding the life-cycle of radio sources. The evolutionary stage (e.g. newly born, dying, restarted) of the radio AGN can be derived from their morphology and properties of the radio spectra. The possibilities offered by the new generation of low-frequency radio telescopes make it possible to derive (at least to first order) the time-scale spent in each phase. The presence of a cycle of activity ensures a recurrent impact of the radio jets on their surrounding inter-stellar and inter-galactic medium and, therefore, their relevance for AGN feedback. The last part is dedicated to the recent results showing the effect of jets on the surrounding galactic medium. The predictions made by numerical simulations on the impact of a radio jet (and in particular a newly born jet) on a clumpy medium describe well what is seen by the observations. The high resolution studies of jet-driven outflows of cold gas (HI and molecular) has provided new important addition both in term of quantifying the impact of the outflows and their relevance for feedback as well as for providing an unexpected view of the physical conditions of the gas under these extreme conditions.

Search for long-lived heavy neutral leptons with displaced vertices in proton-proton collisions at $\sqrt{s} =$ 13 TeV

Year: 2022
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for heavy neutral leptons (HNLs), the right-handed Dirac or Majorana neutrinos, is performed in final states with three charged leptons (electrons or muons) using proton-proton collision data collected by the CMS experiment at $\sqrt{s} =$ 13 TeV at the CERN LHC. The data correspond to an integrated luminosity of 138 fb$^{-1}$. The HNLs could be produced through mixing with standard model neutrinos $ν$. For small values of the HNL mass ($\lt$ 20 GeV) and the square of the HNL-$ν$ mixing parameter (10$^{-7}$-10$^{-2}$), the decay length of these particles can be large enough so that the secondary vertex of the HNL decay can be resolved with the CMS silicon tracker. The selected final state consists of one lepton emerging from the primary proton-proton collision vertex, and two leptons forming a displaced, secondary vertex. No significant deviations from the standard model expectations are observed, and constraints are obtained on the HNL mass and coupling strength parameters, excluding previously unexplored regions of parameter space in the mass range 1-20 GeV and squared mixing parameter values as low as 10$^{-7}$.

The final result for C_l is presented in terms of elementary functions with an explicit dependence on the basic cosmological parameters. This result is in a rather good agreement with CMBFAST for a wide range of parameters around concordance model. This allows us to understand the physical reasons for dependence of the particular features of the CMB spectrum on the basic cosmological parameters and to estimate the possible accuracy of their determination. I also analyse the degeneracy of the spectrum with respect to certain combinations of the cosmological parameters.

description: In this paper, we revisit the computation of particle number fluctuations and the Rényi entanglement entropy of a two-dimensional Fermi gas using multi-dimensional bosonization. In particular, we compute these quantities for a circular Fermi surface and a circular entangling surface. Both quantities display a logarithmic violation of the area law, and the Rényi entropy agrees with the Widom conjecture. Lastly, we compute the symmetry-resolved entanglement entropy for the two-dimensional circular Fermi surface and find that, while the total entanglement entropy scales as $R\log R$, the symmetry-resolved entanglement scales as $\sqrt{R\log R}$, where $R$ is the radius of the subregion of our interest.

Discovery of [FeII]- and H2-emission from protostellar jets in the CB3 and CB230 globules

description: Four Bok globules were studied in the Near-Infrared, through narrow-band filters, centered at the 1.644 micron line of [FeII], the H2-line at 2.122 micron, and the adjacent continuum. We report the discovery of [FeII] and H2 protostellar jets and knots in the globules CB3 and CB230. The [FeII]-jet in CB230 is defined by a continuous elongated emission feature, superimposed on which two knots are seen; the brighter one lies at the tip of the jet. The jet is oriented in the same direction as the large-scale CO outflow, and emerges from the nebulosity in which a Young Stellar Object is embedded. The H2 emission associated with this jet is fainter and wider than the [FeII] emission, and is likely coming from the walls of the jet-channel. In CB3 four H2 emission knots are found, all towards the blue-shifted lobe of the large-scale outflow. There is a good correspondence between the location of the knots and the blue-shifted SiO(5-4) emission, confirming that SiO emission is tracing the jet-like flow rather well. No line emission is found in the other two targets, CB188 and CB205, although in CB205 faint line emission may have been hidden in the diffuse nebulosity near the IRAS position. Around this position a small group of (> 10) stars is found, embedded in the nebula. A diffuse jet-like feature near this group, previously reported in the literature, has been resolved into individual stars.

Poisson regression model is used as the method of analysis. 195 SMEs in North-Eastern Nigeria form the sample of the study based on two-stage sampling and simple random sampling technique. The results reveal that Social ties, Location, and Nature of operation have a significant positive relationship with the Number of loans receives by SMEs. Similarly, the Number of training and Trust have significant positive impact on the Number of loans received; however, they demonstrate the least impact as compared with the other variables based on the level of significance.
Replica Symmetry Breaking for the Integrable Two-Site Sachdev-Ye-Kitaev Model

description: We analyze a two-body nonhermitian two-site Sachdev-Ye-Kitaev model with the couplings of one site complex conjugated to the other site. This model, with no explicit coupling between the sites, shows an infinite number of phase transitions which is a consequence of the partition function factorizing into a product over Matsubara frequencies. We calculate the quenched free energy in two different ways, first in terms of the single-particle energies, and second by solving the Schwinger-Dyson equations. The first calculation can be done entirely in terms of a one-site model. The conjugate replica enters due to non-analyticities when Matsubara frequencies enter the spectral support of the coupling matrix. The second calculation is based on the replica trick of the two-site partition function. Both methods give the same result. The free-fermion partition function can be rephrased as a matrix model for the coupling matrix. Up to minor details, this model is the random matrix model that describes the chiral phase transition of QCD, and the order parameter of the two-body model corresponds to the chiral condensate of QCD. Comparing to the corresponding four-body model, we are able to determine which features of the free energy are due to chaotic nature of the four-body model. The high-temperature phase of both models is entropy dominated, and in both cases is determined by the spectral density. The four-body SYK model has a low-temperature phase whose free energy is almost temperature-independent, signaling an effective gap of the theory even though the actual spectrum does not exhibit a gap. However the low-temperature free energy of the two-body SYK model is not flat, in fact it oscillates to arbitrarily low temperature. This indicates a less desirable feature that the entropy of the two-body model is not always positive, which most likely is a consequence of the nonhermiticity.

Coronal stripping in supersaturated stars
Creators: name: Jardine, Moira
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A recent unambiguous detection of X-ray rotational modulation of the supersaturated star VXR45 (P = 0.223 days) has shown that its corona has discrete dark and bright X-ray regions. We suggest that due to the rapid rotation, the X-ray emitting corona has been centrifugally stripped away, creating open field regions that are dark in X-rays. This leads naturally both to a significant rotational modulation in X-rays but also to the lower X-ray luminosity of supersaturated stars compared to those rotating more slowly. To demonstrate the effect, we take as an example a more slowly rotating star for which surface magnetograms are available. We extrapolate the potential coronal magnetic field based on these magnetograms and determine for a hydrostatic, isothermal atmosphere the structure of the density and of the optically-thin X-ray emission. We show that if the rotation rate of this star were increased, the magnitude of the X-ray luminosity would decrease while its rotational modulation would increase in a way that is consistent with the recent observations of VXR45.

description: The kinetic energy of supersonic turbulence within interstellar clouds is subject to cooling by dissipation in shocks and subsequent line radiation. The clouds are therefore susceptible to a condensation process controlled by the specific entropy. In a form analogous to the thermodynamic entropy, the entropy for supersonic turbulence is proportional to the log of the product of the mean turbulent velocity and the size scale. We derive a dispersion relation for the growth of entropic instabilities in a spherical self-gravitating cloud and find that there is a critical maximum dissipation time scale, about equal to the crossing time, that allows for fragmentation and subsequent star formation. However, the time scale for the loss of turbulent energy may be shorter or longer, for example with rapid thermal cooling or the injection of mechanical energy. Differences in the time scale for energy loss in different star-forming regions may result in differences in the outcome, for example, in the initial mass function.

description: The chiral SU(3) quark model is extended to include an antiquark in order to study the kaon-nucleon system. The model input parameters $b_u$, $m_u$, $m_s$ are taken to be the same as in our previous work which focused on the nucleon-nucleon and nucleon-hyperon interactions. The mass of the scalar meson $σ$ is chosen to be 675 MeV and the mixing of $σ_0$ and $σ_8$ is considered. Using this model the kaon-nucleon $S$ and $P$ partial waves phase shifts of isospin I=0 and I=1 have been studied by solving a resonating group method (RGM) equation. The numerical results of $S_{01}$, $S_{11}$, $P_{01}$, $P_{03}$, and $P_{11}$ partial waves are in good agreement with the experimental data while the phase shifts of $P_{13}$ partial wave are a little bit too repulsive when the laboratory momentum of the kaon meson is greater than 500 MeV in this present calculation.

description: An experimental scheme is proposed for building massively multipartite entangled states using both the spatial and the frequency modes of an optical parametric oscillator. We provide analytical forms of the entangled states using the squeezed eigenmodes of Heisenberg equations, a.k.a. the nullifiers of the corresponding graph state. This scheme can generate, in parallel, several cluster states described by sparsely connected, bicolorable graph states, usable for one-way quantum computing. We indicate the experimentally accessible quantum graphs, depending on the squeezing parameter.

description: We analyze the recently proposed Spectral Quark Model in the light of Chiral Perturbation Theory in curved space-time. In particular, we calculate the chiral coefficients $L_1, ..., L_{10}$, as well as the coefficients $L_{11}$, $L_{12}$, and $L_{13}$, appearing when the model is coupled to gravity. The analysis is carried for the SU(3) case. We analyze the pattern of chiral symmetry breaking as well as elaborate on the fulfillment of anomalies. Matching the model results to resonance meson exchange yields the relation between the masses of the scalar, tensor and vector mesons, $M_{f_0}=M_{f_2}=\sqrt{2} M_V= 4 \sqrt{3 /N_c} πf_π$. Finally, the large-$N_c$ limit suggests the dual relations in the vector and scalar channels, $M_V=M_S= 2 \sqrt{6 /N_c} πf_π$ and $^{1/2}_S = < r^2 >^{1/2}_V = 2 \sqrt{N_c} / f_π= 0.59 {\rm fm} $.

description: We demonstrate that superconducting radio-frequency cavities can be used to create and detect millicharged particles and are capable of extending the reach to couplings several orders of magnitude beyond other laboratory based constraints. Millicharged particles are Schwinger pair-produced in driven cavities and quickly accelerated out of the cavity by the large electric fields. The electric current generated by these particles is detected by a receiver cavity. A light-shining-through-walls experiment may only need to reanalyze future data to provide new constraints on millicharged particles.

description: We present the first X-ray observation of Jupiter by XMM-Newton. Images taken with the EPIC cameras show prominent emission, essentially all confined to the 0.2-2.0 keV band, from the planet's auroral spots; their spectra can be modelled with a combination of unresolved emission lines of highly ionised oxygen (OVII and OVIII), and a pseudo-continuum which may also be due to the superposition of many weak lines. A 2.8 sigma enhancement in the RGS spectrum at 21-22 A (~0.57 keV) is consistent with an OVII identification. Our spectral analysis supports the hypothesis that Jupiter's auroral emissions originate from the capture and acceleration of solar wind ions in the planet's magnetosphere, followed by X-ray production by charge exchange. The X-ray flux of the North spot is modulated at Jupiter's rotation period. We do not detect evidence for the ~45 min X-ray oscillations observed by Chandra more than two years earlier. Emission from the equatorial regions of the planet's disk is also observed. Its spectrum is consistent with that of scattered solar X-rays.

description: Background: Voluntary reporting of Adverse Drug Reactions (ADRs) by physicians and other healthcare professionals currently is the single most important source of information for early signal detection of ADRs. Despite the importance of ADR reporting, there is evidence that less than 10% of ADRs experienced by Canadians are reported to Health Canada and the factors contributing to this under-reporting are unclear. Objectives: The purpose of the present study was to ascertain the barriers to reporting ADRs, including knowledge; attitudes and beliefs; and the accessibility of the reporting system as the first step in understanding the problem of underreporting of ADRs. In addition, information was collected about physician engagement in a dialogue about ADRs with their patients, and whether their office practice was structured to allow patient follow-up of an ADR. Methods: An online survey was administered to BC physicians in the spring of 2008. The survey was designed to obtain information in the following areas: knowledge of and attitudes toward ADRs; patient dialogue about ADRs and structure of the clinical practice; access to the report form, knowledge about if and what needs to be reported and educational support required for ADR reporting and appropriate utilization of new medications. Results: Eighty-seven physicians completed the survey, a response rate of 2%. There is a 95% level of certainty that the quantitative results provided in this survey are within a sampling margin of error of plus or minus 10.5%. Descriptive statistics were calculated and responses to some questions were analyzed using cross-tabulation by whether the physician had ever reported an ADR. A difference of p<0.05 was considered significant. The majority viewed the reporting of ADRs as a professional responsibility, discussed ADRs with their patients and structured their office practice to permit follow-up with suspected ADRs. However, 70% percent had never reported an ADR. Gaps in knowledge about adverse drug reactions and the subsequent reporting process were revealed. Participants indicated the need for decision-making support at the time an ADR is suspected and feedback on the reports they submit. Conclusion: The responses of this small and highly motivated subset of physicians, indicate that difficulties in the actual mechanism of reporting ADRs, rather than negative physician attitudes as suggested in the literature, may be an important first barrier to reporting.

description: A new miniaturized dual-mode microstrip bandpass filter is presented. The filter structure has been fractally generated based on the 4th iteration Minkowski-like pre-fractal geometry, using the conventional dual-mode square ring resonator as the initiator in the fractal generation process. It has been found that the presented filter possesses a size reduction of about 88% as compared with the dual-mode bandpass filter based on the conventional square ring resonator. In addition; simulation results show that the filter has acceptable return loss and transmission responses besides the miniaturized size gained.

description: MAVIS (the MCAO-Assisted Visible Imager and Spectrograph), planned for the VLT Adaptive Optics Facility, represents an innovative step in Multi-Conjugate Adaptive Optics (MCAO) systems, particularly in its operation at visible wavelengths and anticipated contributions to the field of astronomical astrometry. Recognizing the crucial role of high-precision astrometry in realizing science goals such as studying the dynamics of dense starfields, this study focuses on the challenges of advancing astrometry with MAVIS to its limits, as well as paving the way for further enhancement by incorporating telemetry data as part of the astrometric analysis. We employ MAVISIM, Superstar, and DAOPHOT to simulate both MAVIS imaging performance and provide a pathway to incorporate telemetry data for precise astrometry with MAVIS. Photometry analyses are conducted using the Superstar and DAOPHOT platforms, integrated into a specifically designed pipeline for astrometric analysis in MCAO settings. Combining these platforms, our research aims to elucidate the impact of utilizing telemetry data on improving astrometric precision, potentially establishing new methods for ground-based AO-assisted astrometric analysis. This endeavor not only sheds light on the capabilities of MAVIS but also paves the way for advancing astrometry in the era of next-generation MCAO-enabled giant telescopes.

ADAPTIVE OPTICS

description: The Thirty Meter Telescope will use a sophisticated adaptive optics system called NFIRAOS. This system utilizes two deformable mirrors conjugate to 0 km and 11.2 km to apply a Multi-Conjugate Adaptive Optics (MCAO) correction over a 2 arcminute field of view. DM0 and DM11 have 63 and 75 actuators across their respective diameters. To study the behavior of these mirrors, we have developed a low-cost, very high-order Shack-Hartmann Wavefront Sensor (WFS). We will use our WFS to calibrate the flatness of the DMs and measure the influence functions of the actuators. NFIRAOS is cooled to reduce the thermal emissivity of optical surfaces visible to the science detectors, so we will also measure the behaviour of the DMs in both warm and cold environments. As the cold chamber is prone to vibrations, a WFS is preferred to a phase-shifting interferometer. Our design was driven by the need to be able to evaluate the DM surface between the actuators, which led to the requirement of at least 248 sub apertures across the diameter. The largest commercially available Shack-Hartmann WFS has only 128 sub-apertures across the diameter, which is not enough to properly sample these DMs. Furthermore, the designed sensor is able to record the wavefront at 50 FPS (50 times per second) at full resolution. To fabricate this WFS, we used a commercial off-the-shelf CMOS detector, camera lens, and lens let array, which kept the total cost less than 20K USD. Here we present the design and performance characteristics of this device.

description: Storing the ever-increasing amount of data generated by LHC experiments is still inconceivable without making use of the cost effective, though inherently complex, tape technology. GridKa tape storage system used to rely on IBM Spectrum Protect (SP). Due to a variety of limitations and to meet the even higher requirements of HL-LHC project, GridKa decided to switch from SP to High Performance Storage System (HPSS).
Even though HPSS is a highly scalable and performant tape management software, it required special adjustments to fulfill all GridKa requirements. Based on the experience gained with the former tape system, the implementation team developed specific stress scenarios. Running these tests and interpreting their results allowed a successful adaptation of HPSS and made it the core component of GridKa tape storage system.
To increase the performance the architecture of the system was reshaped and the stored data has been collocated in a more appropriate, tape-oriented way to match the requirements of every single experiment and HPSS demands. In total 70 PB of data and 40 million files were migrated from the legacy to the new tape system at GridKa. 
This contribution presents the internal architecture of the new tape storage system, the implementation and migration process, the encountered issues, the achieved results and ongoing work on open items.
