description: Globally, forests cover about four billion hectares. Ethiopia forest cover is about 3% of the
total land area which is far much below the internationally recommended 10% per country.
More than 1.6 billion people globally depend on forests for their livelihood. Ethiopia is one
of the worlds fastest population growth accelerated environmental degradation and
structural food insecurity. In Ethiopia the factors accelerated forest resource degradation
has the major threat to rural livelihoods and sustainable natural resource management in the
country. The objective of study of this study is to determine socio-economic factors affecting
sustainable management of Gorte forest, assess to current forest conservation activity. A
descriptive research design was used. Purposive sampling was used in the study and the
sample size was 182 respondents, Data was collected using questionnaire, satellite image,
interview and observation. Data was analyzed using descriptive analysis by the help of
statistical package for social sciences. The stakeholders are not adequately involved in forest
management. The major causes of deforestation in study area were agricultural land
expansion, cutting down of tree for fuel wood and charcoal production, settlement expansion
and timber harvest for construction purpose. Efforts should thus be focused on those factors
that affect sustainable management of the forest.

description: We present the merging of the Particle-Mesh (PM) relativistic Gevolution code with the TreePM Gadget-4 code, with the aim of studying general relativity effects in cosmology. Our code, called GrGadget, is able to track the evolution of metric perturbations in the weak field limit by using Gevolution's implementation of a relativistic PM in the Poisson gauge. To achieve this, starting from Gevolution we have written a C++ library called libgevolution, that allows a code to access and use the same abstractions and resources that Gevolution uses for its PM-only N-body simulations. The code works under the assumption that particle interactions at short distances can be approximated as Newtonian, so that we can combine the forces computed with a Newtonian Tree with those computed with a relativistic PM. The result is a TreePM simulation code that represents metric perturbations at the scales where they are relevant, while resolving non-linear structures. We validate our code by closely matching Gadget-4 forces, computed with the Tree switched off, with those computed with libgevolution in the Newtonian limit. With GrGadget we obtain a matter power spectrum that is compatible with Newtonian Gadget at small scales and contains GR features at large scales that are consistent with results obtained with Gevolution. We demonstrate that, due to the better resolution of the highly non-linear regime, the representation of the relativistic fields sampled on the mesh improves with respect to the PM-only simulations.

AbstractBelzutifan (Welireg™) is an oral small molecule inhibitor of hypoxia-inducible factor (HIF)-2α being developed by Peloton Therapeutics for the treatment of solid tumours, including renal cell carcinoma (RCC) with clear cell histology (ccRCC) and von Hippel-Lindau (VHL) disease-associated RCC. In August 2021, belzutifan received its first approval in the USA for the treatment of patients with VHL disease who require therapy for associated RCC, central nervous system (CNS) haemangioblastomas or pancreatic neuroendocrine tumours (pNET), not requiring immediate surgery. Clinical studies of belzutifan (as monotherapy or combination therapy) in other indications, including ccRCC, pNET and phaeochromocytoma/paraganglioma, are also underway in various countries. This article summarizes the milestones in the development of belzutifan leading to this first approval for certain VHL disease-associated tumours.© Springer Nature Switzerland AG 2021

description: We obtain local unitary invariant polynomials for N qubit quantum state from first principles. A basic unit of entanglement, referred to as negativity font, is defined as a two by two matrix of probability amplitudes that determines the negative eigen value of a four by four submatrix of partially transposed state operator. Transformation properties of determinants of negativity fonts under local unitary (LU) transformations are exploited to obtain multi qubit invariants written in terms of such determinants.

Synchrotron Afterglow Model for AT 2022cmc: Jetted Tidal Disruption Event or Engine-Powered Supernova?
Creators: name: Matsumoto, Tatsuya

Publisher: name: arXiv
Year: 2023
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: AT 2022cmc is a luminous optical transient ($νL_ν \gtrsim 10^{45}$ erg s$^{-1}$) accompanied by decaying non-thermal X-rays (peak duration $t_{\rm X} \lesssim$ days and isotropic energy $E_{\rm X,iso} \gtrsim 10^{53}$ erg) and a long-lived radio/mm synchrotron afterglow, which has been interpreted as a jetted tidal disruption event (TDE). Both an equipartition analysis and a detailed afterglow model reveals the radio/mm emitting plasma to be expanding mildly relativistically (Lorentz factor $Γ\gtrsim\,few$) with an opening angle $θ_{\rm j}\simeq0.1$ and roughly fixed energy $E_{\rm j,iso} \gtrsim few \times 10^{53}$ erg into an external medium of density profile $n \propto R^{-k}$ with $k \simeq 1.5-2$, broadly similar to that of the first jetted TDE candidate Swift J1644+57 and consistent with Bondi accretion at a rate $\sim 10^{-3}\dot{M}_{\rm Edd}$ onto a $10^{6}M_{\odot}$ black hole before the outburst. The rapidly decaying optical emission over the first days is consistent with fast-cooling synchrotron radiation from the same forward shock as the radio/mm emission, while the bluer slowly decaying phase to follow likely represents a separate thermal emission component. Emission from the reverse shock may have peaked during the first days, but whose non-detection in the optical band places an upper bound $Γ_{\rm j} \lesssim 100$ on the Lorentz factor of the unshocked jet. Although a TDE origin for AT 2022cmc is indeed supported by some observations, the vast difference between the short-lived jet activity phase $t_{\rm X} \lesssim$ days relative to the months-long thermal optical emission, also challenges this scenario. A stellar core-collapse event giving birth to a magnetar or black hole engine of peak duration $\sim 1$ day offers an alternative model also consistent with the circumburst environment, if interpreted as a massive-star wind.

description: Our aims are twofold: To determine the physical parameters of PMS members in young open clusters (YOCs), and to check and compare the performances of different model isochrones. We compare UBVRI photometric observations of YOCs to theoretical isochrones in the photometric diagrams. The comparison simultaneously provides membership assignments for MS and PMS stars, and estimates for the masses, ages, and spatial distribution of the candidate members. The relations found between the different cluster parameters show that the procedure applied to assign cluster membership, and to measure physical parameters for the selected members, is well founded.

description: We report the discovery of burst oscillations at the spin frequency in ten thermonuclear bursts from the accreting millisecond X-ray pulsar (AMXP) IGR J17511-3057. The burst oscillation properties are, like those from the persistent AMXPs SAX J1808.4-3658 and XTE J1814-338, anomalous compared to burst oscillations from intermittent pulsars or non-pulsing LMXBs. Like SAX J1808.4-3658 they show frequency drifts in the rising phase rather than the tail. There is also evidence for harmonic content. Where IGR J17511-3057 is unusual compared to the other two persistent pulsars is that oscillations are not detected throughout all bursts. As accretion rate drops the bursts get brighter and their rise/decay time scales become shorter, while the oscillation amplitude falls below the detection threshold: first in the burst peak and then also in the rise. None of the bursts from IGR J17511-3057 show evidence for photospheric radius expansion (which might be expected to suppress oscillation amplitude) which allow us to set an upper limit to the distance of 6.9 kpc. We discuss the implications of our results for models of the burst oscillation mechanism.

description: As the statistical power of imaging surveys grows, it is crucial to account for all systematic uncertainties. This is normally done by constructing a model of these uncertainties and then marginalizing over the additional model parameters. The resulting high dimensionality of the total parameter spaces makes inferring the cosmological parameters significantly more costly using traditional Monte-Carlo sampling methods. A particularly relevant example is the redshift distribution, $p(z)$, of the source samples, which may require tens of parameters to describe fully. However, relatively tight priors can be usually placed on these parameters through calibration of the associated systematics. In this paper we show, quantitatively, that a linearisation of the theoretical prediction with respect to these calibratable systematic parameters allows us to analytically marginalise over these extra parameters, leading to a factor $\sim30$ reduction in the time needed for parameter inference, while accurately recovering the same posterior distributions for the cosmological parameters that would be obtained through a full numerical marginalisation over 160 $p(z)$ parameters. We demonstrate that this is feasible not only with current data and current achievable calibration priors but also for future Stage-IV datasets.

description: We present 0.4 arcsec-resolution imaging polarimetry at 8.7, 10.3, and 12.5 microns, obtained with CanariCam at the Gran Telescopio Canarias, of the central region of W51 IRS2. The polarization, as high as 14 percent, arises from silicate particles aligned by the interstellar magnetic field. We separate, or unfold, the polarization of each sightline into emission and absorption components, from which we infer the morphologies of the corresponding projected magnetic fields that thread the emitting and foreground-absorbing regions. We conclude that the projected magnetic field in the foreground material is part of the larger-scale ambient field. The morphology of the projected magnetic field in the mid-IR emitting region spanning the cometary HII region W51 IRS2W is similar to that in the absorbing region. Elsewhere, the two magnetic fields differ significantly with no clear relationship between them. The magnetic field across the W51 IRS2W cometary core appears to be an integral part of a champagne outflow of gas originating in the core and dominating the energetics there. The bipolar outflow, W51north jet, that appears to originate at or near SMA1/N1 coincides almost exactly with a clearly demarcated north-south swath of lower polarization. While speculative, comparison of mid-IR and submm polarimetry on two different scales may support a picture in which SMA1/N1 plays a major role in the magnetic field structure across W51 IRS2.

description: Multivariate machine learning techniques provide an alternative to the rapidity gap method for event-by-event identification and classification of diffraction in hadron-hadron collisions. Traditionally, such methods assign each event exclusively to a single class producing classification errors in overlap regions of data space. As an alternative to this so called hard classification approach, we propose estimating posterior probabilities of each diffractive class and using these estimates to weigh event contributions to physical observables. It is shown with a Monte Carlo study that such a soft classification scheme is able to reproduce observables such as multiplicity distributions and relative event rates with a much higher accuracy than hard classification.

description: By interpreting a temporal network as a trajectory of a latent graph dynamical system, we introduce the concept of dynamical instability of a temporal network, and construct a measure to estimate the network Maximum Lyapunov Exponent (nMLE) of a temporal network trajectory. Extending conventional algorithmic methods from nonlinear time-series analysis to networks, we show how to quantify sensitive dependence on initial conditions, and estimate the nMLE directly from a single network trajectory. We validate our method for a range of synthetic generative network models displaying low and high dimensional chaos, and finally discuss potential applications.

description: about current recordkeeping environments. We begin by explaining recordkeeping informatics, a continuum based approach to managing authoritative information in the ever shifting, complex and technologically challenging times that confront all of us, including organisations. We then develop these ideas through a case study of recordkeeping requirements for those who as children experience out of home care as a result of child welfare and protection policies. Out of home care is the term used in Australia for “the care of children and young people up to 18 years who are unable to live with their families, often due to child abuse and neglect. It involves the placement of a child or young person with alternate caregivers on a short- or long-term basis” (Australian Institute of Family Studies, 2015). These experiences place lifelong identity, memory and accountability needs on the governments and organisations providing these services. Our case study will explore the macro and micro challenges that arise for individuals, organisations, governments and societies as a demonstration of the utility of recordkeeping informatics in designing archival futures in which multiple rights in records are embedded.

description: JWST has now made it possible to probe the rest-frame optical line emission of high-redshift galaxies extending to z~9, and potentially beyond. To aid in the interpretation of these emerging constraints, in this work we explore predictions for [OIII] emission in high-redshift galaxies using the First Light and Reionisation Epoch Simulations (FLARES). We produce predictions for the [OIII] luminosity function, its correlation with the UV luminosity, and the distribution of equivalent widths (EWs). We also explore how the [OIII] EW correlates with physical properties including specific star formation rate, metallicity, and dust attenuation. Our predictions are largely consistent with recent observational constraints on the luminosity function, average equivalent widths, and line ratios. However, they fail to reproduce the observed tail of high-EW sources and the number density of extreme line emitters. Possibilities to explain these discrepancies include an additional source of ionising photons and/or greater stochasticity in star formation in the model or photometric scatter and/or bias in the observations. With JWST now rapidly building larger samples and a wider range of emission lines the answer to this remaining discrepancy should be available imminently.

description: Based on numerical simulations that we have carried out, we provide evidence that for regular polygons with $σ= 6j$ sides (with $j=2,3,\dots$), $N(k)=3 k (k+1)+1$ (with $k=1,2,\dots$) congruent disks of appropriate size can be nicely packed inside these polygons in highly symmetrical configurations which apparently have maximal density for $N$ sufficiently small. These configurations are invariant under rotations of $π/3$ and are closely related to the configurations with perfect hexagonal packing in the regular hexagon and to the configurations with {\sl curved hexagonal packing} (CHP) in the circle found long time ago by Graham and Lubachevsky. At the basis of our explorations are the algorithms that we have devised, which are very efficient in producing the CHP and more general configurations inside regular polygons. We have used these algorithms to generate a large number of CHP configurations for different regular polygons and numbers of disks; a careful study of these results has made possible to fully characterize the general properties of the CHP configurations and to devise a {\sl deterministic} algorithm that completely ensembles a given CHP configuration once an appropriate input ("DNA") is specified. Our analysis shows that the number of CHP configurations for a given $N$ is highly degenerate in the packing fraction and it can be explicitly calculated in terms of $k$ (number of shells), of the building block of the DNA itself and of the number of vertices in the fundamental domain (because of the symmetry we work in $1/6$ of the whole domain). With the help of our deterministic algorithm we are able to build {\sl all} the CHP configurations for a polygon with $k$ shells.

Strengthening networks to improve knowledge translation in paediatric healthcare
Creators: name: Glegg, Stephanie Miranda Nadine
Publisher: name: University of British Columbia
Year: 2019

description: Background: Knowledge translation (KT), or the process of moving research into action, takes 10-20 years, resulting in sub-optimal healthcare for Canadians. Most KT strategies designed to shorten this gap neglect the social factors that facilitate research use. Social network analysis (SNA) methodology can be used to examine these factors within a network of individuals, including identifying influential people, and describing interaction patterns that can be targeted to improve KT efficiency. No such studies exist in paediatric healthcare organizations. Aims: 1) determine how SNA can augment KT research; 2) describe the national KT support context within paediatric healthcare and research organizations; and 3) confirm the influence of networks on KT, and identify network-driven KT support strategies. Methods: Study 1: Scoping review of SNA and theory applied to KT research. Study 2: Survey-based environmental scan of organizational KT supports in Canadian paediatric healthcare and research organizations. Study 3: Mixed-methods SNA descriptive case study of one healthcare-research organization dyad’s KT network using visual tools, and SNA survey and interview data from researchers, clinicians, leaders and KT support personnel to triangulate network influences on KT, and to identify network interventions to facilitate KT. Results: Study 1: SNA use is emerging in the KT field, primarily to examine information flow through cross-sectional survey research of physician-only networks, while analyzing few network properties. Diverse theoretical perspectives appear to be applicable for SNA research. Study 2: Organizational supports for KT typically targeted healthcare professionals, leaders and researchers, and included library services, KT support personnel, internal and external collaborations, forums and communication strategies, policies and protocols, consultation, specialized initiatives and funding. Study 3: Multiple network structures were perceived to influence KT. Reasons for network structure included individual attributes, relational considerations, and organizational context. Proposed network-driven KT support strategies included network development, communication, resources, personnel, visibly valuing KT, and evaluation. Conclusion: SNA can advance the science of KT by addressing the under-researched social determinants of evidence use, and by informing the design of network interventions. Participant engagement in applying a network perspective represented a novel application of SNA to KT research.

description: Stellar coronal mass ejections (CMEs) have recently received much attention for their impacts on exoplanets and stellar evolution. Detecting prominence eruptions, the initial phase of CMEs, as the blue-shifted excess component of Balmer lines is a technique to capture stellar CMEs. However, most of prominence eruptions identified thus far have been slow and less than the surface escape velocity. Therefore, whether these eruptions were developing into CMEs remained unknown. In this study, we conducted simultaneous optical photometric observations with Transiting Exoplanet Survey Satellite and optical spectroscopic observations with the 3.8m Seimei Telescope for the RS CVn-type star V1355 Orionis that frequently produces large-scale superflares. We detected a superflare releasing $7.0 \times 10^{35} \: \mathrm{erg}$. In the early stage of this flare, a blue-shifted excess component of $\mathrm{H α}$ extending its velocity up to $760-1690 \: \mathrm{km \: s^{-1}}$ was observed and thought to originate from prominence eruptions. The velocity greatly exceeds the escape velocity (i.e., $\sim 350 \: \mathrm{km \: s^{-1}}$), which provides important evidence that stellar prominence eruptions can develop into CMEs. Furthermore, we found that the prominence is very massive ($9.5 \times 10^{18} \: \mathrm{g} < M < 1.4 \times 10^{21} \: \mathrm{g}$). These data will clarify whether such events follow existing theories and scaling laws on solar flares and CMEs even when the energy scale far exceeds solar cases.

description: INTRODUCTION AND OBJECTIVES: Chronic hepatitis B virus (HBV) infection is a major risk factor for hepatocellular carcinoma (HCC). In African populations, HCC frequently presents at an advanced stage with poor outcomes. We applied whole genome sequencing (WGS) to compare HBV genomes in individuals with and without HCC. MATERIALS AND METHODS: We identified adults with HBV infection, with and without complicating HCC, in Cape Town, South Africa. We generated HBV WGS using pan-genotypic probe-based enrichment followed by Illumina sequencing. RESULTS: Compared to the non-HCC group, HCC patients were more likely to be male (p<0.0001), older (p=0.01), HIV-negative (p=0.006), and have higher HBV viral loads (p<0.0001). Among 19 HCC and 12 non-HCC patients for whom WGS was obtained, genotype A dominated (74%), of which 96% were subgenotype A1. PreS2 deletions (Δ38-55) were enriched in HBV sequences from HCC patients (n=7). The sequence motif most strongly associated with HCC comprised either a deletion or polymorphism at site T53 in PreS2 - collectively coined 'non-T53' - together with a basal core promoter (BCP) mutation G1764A (AUROC = 0.79). CONCLUSIONS: In this setting, HBV sequence polymorphisms and deletions are associated with HCC, and 'non-T53+G1764A' represents a putative signature motif for HCC. Additional investigations are needed to disaggregate the impact of other demographic, clinical, and environmental influences, to ascertain the extent to which viral polymorphisms contribute to oncogenesis, and to determine whether HBV sequence is a useful biomarker for HCC risk stratification.
Selective Adsorption and Chiral Amplification of Amino Acids in Vermiculite Clay -Implications for the origin of biochirality

description: Smectite clays are hydrated layer silicates that, like micas, occur naturally in abundance. Importantly, they have readily modifiable interlayer spaces that provide excellent sites for nanochemistry. Vermiculite is one such smectite clay and in the presence of small chain-length alkyl-NH3Cl ions, forms sensitive, 1-D ordered model clay systems with expandable nano-pore inter-layer regions. These inter-layers readily adsorb organic molecules. N-propyl NH3Cl vermiculite clay gels were used to determine the adsorption of alanine, lysine and histidine by chiral HPLC. The results show that during reaction with fresh vermiculite interlayers, significant chiral enrichment of either L- and D-enantiomers occurs depending on the amino acid. Chiral enrichment of the supernatant solutions is up to about 1% per pass. In contrast, addition to clay interlayers already reacted with amino acid solutions resulted in little or no change in D/L ratio during the time of the experiment. Adsorption of small amounts of amphiphilic organic molecules in clay inter-layers is known to produce Layer-by-Layer or Langmuir-Blodgett films. Moreover atomistic simulations show that self-organization of organic species in clay interlayers is important. These non-centrosymmetric, chirally active nanofilms may cause clays to act subsequently as chiral amplifiers, concentrating organic material from dilute solution and having different adsorption energetics for D- and L-enantiomers. The additional role of clays in RNA oligimerization already postulated by Ferris and others, together with the need for the organization of amphiphilic molecules and lipids noted by Szostak and others, suggests that such chiral separation by clays in lagoonal environments at normal biological temperatures might also have played a significant role in the origin of biochirality.

description: Programmable unitary photonic devices are emerging as promising tools to implement unitary transformation for quantum information processing, machine learning, and optical communication. These devices typically use a rectangular mesh of Mach-Zehnder interferometers (MZIs), which has a clear mathematical structure and can be configured deterministically. However, this mesh architecture is sensitive to fabrication errors, and the correction techniques are still under investigation. In contrast, the multi-plane light conversion (MPLC) architecture is more robust against fabrication errors, but a deterministic method for configuring the converter has not yet been developed due to its complex mathematical structure. In this work, we propose a fast iterative configuration method for MPLC, following the mathematical review of the matrix distance and proposal of a new norm. We show through numerical simulations that adding a few redundant layers significantly improves the convergence of the MPLC architecture, making it a practical and attractive option. We also consider the effects of finite resolution and crosstalk in phase shifters in our simulations. In addition, we propose a phase-insensitive distance suited for applications using only intensity detections. Our method demonstrates orders of magnitude better accuracy and a 20-fold speed-up compared to previous approaches.

description: We consider an isotropic Fermi liquid in two dimensions near the n=2 Pomeranchuk instability in the charge channel. The order parameter is a quadrupolar stress tensor with two polarizations, longitudinal and transverse to the quadrupolar momentum tensor. Longitudinal and transverse bosonic modes are characterized by dynamical exponents z_parallel=3 and z_perp=2, respectively. Previous studies have found that such a system exhibits multiscale quantum criticality with two different energy scales omega ~ xi^{-z_{parallel,perp}}, where xi is the correlation length. We study the impact of the multiple energy scales on the electron Green function. The interaction with the critical z_parallel =3 mode is known to give rise to a local self-energy that develops a non-Fermi liquid form, Sigma(omega) ~ omega^{2/3} for frequencies larger than the energy scale omega ~ xi^{-3}. We find that the exchange of transverse z_perp=2 fluctuations leads to a logarithmically singular renormalizations of the quasiparticle residue Z and the vertex Gamma. We derive and solve renormalization group equations for the flow of Z and Gamma and show that the system develops an anomalous dimension at the nematic quantum-critical point (QCP). As a result, the spectral function at a fixed omega and varying k has a non-Lorentzian form. Away from the QCP, we find that the flow of Z is cut at the energy scale omega_{FL} ~ xi^{-1}, associated with the z=1 dynamics of electrons. The z_perp=2 energy scale, omega ~ xi^{-2}, affects the flow of Z only if one includes into the theory self-interaction of transverse fluctuations.
