description: We report two epochs of Chandra-ACIS X-ray imaging spectroscopy of the nearby bright Type IIn supernova SN 2010jl, taken around 2 months and then a year after the explosion. The majority of the X-ray emission in both the spectra is characterized by a high temperature ($\ga 10$ keV) and is likely to be from the forward shocked region resulting from circumstellar interaction. The absorption column density in the first spectrum is high, ~ 10^{24} cm^{-2}, more than 3 orders of magnitude higher than the Galactic absorption column, and we attribute it to absorption by circumstellar matter. In the second epoch observation, the column density has decreased by a factor of 3, as expected for shock propagation in the circumstellar medium. The unabsorbed 0.2-10 keV luminosity at both epochs is ~7 x 10^{41} erg/s. The 6.4 keV Fe line clearly present in the first spectrum is not detected in the second spectrum. The strength of the fluorescent line is roughly that expected for the column density of circumstellar gas, provided the Fe is not highly ionized. There is also evidence for an absorbed power law component in both the spectra, which we attribute to a background ultraluminous X-ray source.

description: We present the ultraviolet (UV) color-color relation of early-type galaxies (ETGs) in the nearby universe (0.05 < z < 0.12) to investigate the properties of hot stellar populations responsible for the UV excess (UVX). The initial sample of ETGs is selected by the spectroscopic redshift and the morphology parameter from the Sloan Digital Sky Survey (SDSS) DR7, and then cross-matched with the Galaxy Evolution Explorer (GALEX) Far-UV (FUV) and Near-UV (NUV) GR6 data. The cross-matched ETG sample is further classified by their emission line characteristics in the optical spectra into quiescent, star-forming, and AGN categories. Contaminations from early-type spiral galaxies, mergers, and morphologically disturbed galaxies are removed by visual inspection. By drawing the FUV - NUV (as a measure of UV spectral shape) vs. FUV - r (as a measure of UVX strength) diagram for the final sample of ~3700 quiescent ETGs, we find that the "old and dead" ETGs consist of a well-defined sequence in UV colors, the "UV red sequence", so that the stronger UVX galaxies should have a harder UV spectral shape systematically. However, the observed UV spectral slope is too steep to be reproduced by the canonical stellar population models in which the UV flux is mainly controlled by age or metallicity parameters. Moreover, 2 mag of color spreads both in FUV - NUV and FUV - r appear to be ubiquitous among any subsets in distance or luminosity. This implies that the UVX in ETGs could be driven by yet another parameter which might be even more influential than age or metallicity.

description: We review recent dissipative particle dynamics (DPD) simulations of electrolyte flow in nanochannels. A method is presented by which the slip length $delta_B$ at the channel boundaries can be tuned systematically from negative to infinity by introducing suitably adjusted wall-fluid friction forces. Using this method, we study electroosmotic flow (EOF) in nanochannels for varying surface slip conditions and fluids of different ionic strength. Analytic expressions for the flow profiles are derived from the Stokes equation, which are in good agreement with the numerical results. Finally, we investigate the influence of EOF on the effective mobility of polyelectrolytes in nanochannels. The relevant quantity characterizing the effect of slippage is found to be the dimensionless quantity $κδ_B$, where $1/κ$ is an effective electrostatic screening length at the channel boundaries.

description: We have studied the moment correlations within triangular lattice arrays of single-domain co-aligned nanoscale ferromagnetic islands. Independent variation of lattice spacing along and perpendicular to the island axis tunes the magnetostatic interactions between islands through a broad range of relative strengths. For certain lattice parameters, the sign of the correlations between near-neighbor island moments is opposite to that favored by the pair-wise interaction. This finding, supported by analysis of the total correlation in terms of direct and convoluted indirect contributions across multiple pairwise interactions, indicates that indirect interactions and/or those mediated by further neighbors can be tuned to be dominant, with implications for the wide range of systems composed of interacting nanomagnets.

description: Methicillin-resistant Staphylococcus aureus (MRSA) is a major antimicrobial-resistant pathogen, with infection cases rising from 21% in 2016 to 35% in 2020. This increase has driven research into alternative treatments like antimicrobial peptides (AMPs) and essential oils (EOs), which have shown higher success rates than other options. To support this, we developed The Anti-MRSA Resource (TAMRSAR), a database compiling 1,789 AMPs (1,029 unique) and 863 EOs (671 unique) effective against MRSA. Data was manually extracted from PubMed literature, with integrated tools for sequence analysis and feature assessment. TAMRSAR is freely accessible at https://bblserver.org.in/tamrsar/.

description: Propagation of dressed solitary excitations are studied in a partially degenerate quantum plasma in the framework of quantum-hydrodynamics (QHD) model using multiple scales technique. The evolution equation together with a linear inhomogeneous differential equation is solved using Kodama-Taniuti renormalizing technique. It is shown that the type of solitary excitations (bright or dark) is defined by two critical plasma parameter values.

description: On the basis of systematic measurements of fragmentation reactions, which provide a detailed overview on the velocity distributions of residual nuclei, an improved description of the kinematical properties of the fragmentation residues is established. This work is dedicated to the fluctuations of their momentum distributions. In contrast to previous investigations, limited to close-to-projectile fragments, we extended our study to the entire production range, down to the lightest observed fragments. In this context, beside the contribution of abrasion and evaporation processes, we considered the effect of the thermal break-up on the width of the momentum distributions. Using approximated theoretical descriptions of the different reaction stages, a new analytical formula for the variance of the momentum distribution is derived, which is well adapted to technical applications.

description: We study moderate gravitational lensing where a background galaxy is magnified substantially, but not multiply imaged, by an intervening galaxy. We focus on the case where both the lens and source are elliptical galaxies. The signatures of moderate lensing include isophotal distortions and systematic shifts in the fundamental plane and Kormendy relation, which can potentially be used to statistically determine the galaxy mass profiles. These effects are illustrated using Monte Carlo simulations of galaxy pairs where the foreground galaxy is modelled as a singular isothermal sphere model and observational parameters appropriate for the Large Synoptic Survey Telescope (LSST). The range in radius probed by moderate lensing will be larger than that by strong lensing, and is in the interesting regime where the density slope may be changing.

description: We analyze the dc Josephson effect in a ballistic superconductor/half-metal/superconductor junction by means of the Bogoliubov de Gennes equations. We study the role of spin-active interfaces and compare how different superconductor symmetries, including d-wave pairing, affect the Josephson current. We analyze the critical current as a function of junction width, temperature, and spin-flip strength and direction. In particular, we demonstrate that the temperature dependence of the supercurrent in the dxy symmetry case differs qualitatively from the s and dx2-y2 symmetries. Moreover, we have derived a general analytical expression for the Andreev bound-state energies that shows how one can either induce 0-π transitions or continuously change the ground-state phase of the junction by controlling the magnetic misalignment at the interfaces.

The main transition in the Pink membrane model: finite-size scaling and the influence of surface roughness

description: We consider the main transition in single-component membranes using computer simulations of the Pink model [D. Pink {\it et al.}, Biochemistry {\bf 19}, 349 (1980)]. We first show that the accepted parameters of the Pink model yield a main transition temperature that is systematically below experimental values. This resolves an issue that was first pointed out by Corvera and co-workers [Phys. Rev. E {\bf 47}, 696 (1993)]. In order to yield the correct transition temperature, the strength of the van der Waals coupling in the Pink model must be increased; by using finite-size scaling, a set of optimal values is proposed. We also provide finite-size scaling evidence that the Pink model belongs to the universality class of the two-dimensional Ising model. This finding holds irrespective of the number of conformational states. Finally, we address the main transition in the presence of quenched disorder, which may arise in situations where the membrane is deposited on a rough support. In this case, we observe a stable multi-domain structure of gel and fluid domains, and the absence of a sharp transition in the thermodynamic limit.

description: We study the irreducible decomposition under Sp(2n, R) of the space of torsion tensors of almost symplectic connections. Then a description of all symplectic quadratic invariants of torsion-like tensors is given. When applied to a manifold M with an almost symplectic structure, these instruments give preliminary insight for finding a preferred linear almost symplectic connection on M . We rediscover Ph. Tondeur's Theorem on almost symplectic connections. Properties of torsion of the vectorial kind are deduced.

description: We investigate a stationary process's crypticity---a measure of the difference between its hidden state information and its observed information---using the causal states of computational mechanics. Here, we motivate crypticity and cryptic order as physically meaningful quantities that monitor how hidden a hidden process is. This is done by recasting previous results on the convergence of block entropy and block-state entropy in a geometric setting, one that is more intuitive and that leads to a number of new results. For example, we connect crypticity to how an observer synchronizes to a process. We show that the block-causal-state entropy is a convex function of block length. We give a complete analysis of spin chains. We present a classification scheme that surveys stationary processes in terms of their possible cryptic and Markov orders. We illustrate related entropy convergence behaviors using a new form of foliated information diagram. Finally, along the way, we provide a variety of interpretations of crypticity and cryptic order to establish their naturalness and pervasiveness. Hopefully, these will inspire new applications in spatially extended and network dynamical systems.

Leaving Care im Kanton Bern: Welche Massnahmen braucht es aus der Perspektive der Beistandsperson, damit jungen Erwachsenen im Leaving Care Prozess der Übergang in die Selbstständigkeit gelingt?
Creators: name: Schüpbach, Kristina

description: Die vorliegende Masterarbeit befasst sich mit der Thematik Leaving Care im Kanton Bern. Die Hauptfragestellung der Arbeit lautet: «Welche Massnahmen braucht es aus der Perspektive der Beistandsperson, damit jungen Erwachsenen im Leaving Care Prozess der Übergang in die Selbstständigkeit gelingt?». Care Leaver:innen sind junge Erwachsene, welche ihr ganzes Leben oder einen Teil ihrer Kindheit oder Jugend in einer Institution oder in einer Pflegefamilie gelebt haben, und die kurz vor dem Austritt stehen oder sich bereits mitten im Übergang in das selbstständige Erwachsenenleben befinden. Care Leaver:innen verlassen somit die Institution oder die Pflegefamilie und erreichen den Erwachsenenstatus, wobei es sich um eine Statuspassage handelt, welche Leaving Care genannt wird. Care Leaver:innen sind in diversen Bereichen ihres Lebens benachteiligt, ohne zuverlässige und kontinuierliche Hilfestellungen zu erhalten. Sie müssen den Übergang in den Erwachsenenstatus oft früher meistern als ihre Peers, welche in ihrer Herkunftsfamilie aufgewachsen sind, und die Institution oder die Pflegefamilie innert kurzer Zeit verlassen. Hinzu kommt, dass die Übergänge in das selbstständige Erwachsenenleben oft parallel verlaufen und zudem irreversibel sind. Zu Beginn werden die rechtlichen und die sozialarbeiterischen Grundlagen der Statuspassage Leaving Care sowie die Aufgaben der Beistandsperson im Zusammenhang mit Leaving Care beschrieben. Der Blick auf den internationalen und nationalen Forschungsstand zeigt, dass die häufigsten Herausforderungen von Care Leaver:innen beim Übergang in den Erwachsenenstatus die materiellen Ressourcen, die Herkunftsfamilie und die sozialen Beziehungen, die Bildung, die Wohnsituation und die psychische Gesundheit sind. Es werden daher Handlungsideen erarbeitet, welche es aus der Perspektive der Beistandsperson braucht, um Care Leaver:innen bei diesen Herausforderungen unterstützen zu können. Da Care Leaver:innen jedoch im ganzen Platzierungsprozess Übergänge bewältigen müssen, welche die Statuspassage Leaving Care beeinflussen, wird auf diese diversen Wechsel, von der ausserfamiliären Platzierung bis hin zum Übertritt in das selbstständige Erwachsenenleben, eingegangen. Es wird aufgezeigt, welche Massnahmen es im ganzen Platzierungsprozess braucht, damit die Statuspassage Leaving Care gelingen kann.

Photometric AGN reverberation mapping - an efficient tool for BLR sizes, black hole masses and host-subtracted AGN luminosities

description: Photometric reverberation mapping employs a wide bandpass to measure the AGN continuum variations and a suitable band, usually a narrow band (NB), to trace the echo of an emission line in the broad line region (BLR). The narrow band catches both the emission line and the underlying continuum, and one needs to extract the pure emission line light curve. We performed a test on two local AGNs, PG0003+199 (=Mrk335) and Ark120, observing well-sampled broad- (B, V) and narrow-band light curves with the robotic 15cm telescope VYSOS-6 on Cerro Armazones, Chile. In PG0003+199, H_alpha dominates the flux in the NB by 85%, allowing us to measure the time lag of H_alpha against B without the need to correct for the continuum contribution. In Ark120, H_beta contributes only 50% to the flux in the NB. The cross correlation of the B and NB light curves shows two distinct peaks of similar strength, one at lag zero from the autocorrelated continuum and one from the emission line at tau_cent = 47.5 +/- 3.4 days. We constructed a synthetic H_beta light curve, by subtracting a scaled V light curve, which traces the continuum, from the NB light curve. The cross correlation of this synthetic H_beta light curve with the B light curve shows only one major peak at tau_cent = 48.0 +/- 3.3 days, while the peak from the autocorrelated continuum at lag zero is absent. We conclude that, as long as the emission line contributes at least 50% to the bandpass, the pure emission line light curve can be reconstructed from photometric monitoring data so that the time lag can be measured. For both objects the lags we find are consistent with spectroscopic reverberation results. While the dense sampling (median 2 days) enables us to determine tau_cent with small (10%) formal errors, we caution that gaps in the light curves may lead to much larger systematic uncertainties.

description: Recently mobile agents are used to discover services in mobile ad-hoc network (MANET) where agents travel through the network, collecting and sometimes spreading the dynamically changing service information. But it is important to investigate how reliable the agents are for this application as the dependability issues(reliability and availability) of MANET are highly affected by its dynamic nature.The complexity of underlying MANET makes it hard to obtain the route reliability of the mobile agent systems (MAS); instead we estimate it using Monte Carlo simulation. Thus an algorithm for estimating the task route reliability of MAS (deployed for discovering services) is proposed, that takes into account the effect of node mobility in MANET. That mobility pattern of the nodes affects the MAS performance is also shown by considering different mobility models. Multipath propagation effect of radio signal is considered to decide link existence. Transient link errors are also considered. Finally we propose a metric to calculate the reliability of service discovery protocol and see how MAS performance affects the protocol reliability. The experimental results show the robustness of the proposed algorithm. Here the optimum value of network bandwidth (needed to support the agents) is calculated for our application. However the reliability of MAS is highly dependent on link failure probability.

description: We investigate the effect of photodesorption on the snow line position at the surface of a protoplanetary disk around a Herbig Ae/Be star, motivated by the detection of water ice particles at the surface of the disk around HD142527 by Honda et al. For this aim, we obtain the density and temperature structure in the disk with a 1+1D radiative transfer and determine the distribution of water ice particles in the disk by the balance between condensation, sublimation, and photodesorption. We find that photodesorption induced by the far-ultraviolet radiation from the central star depresses the ice-condensation front toward the mid-plane and pushes the surface snow line outward significantly when the stellar effective temperature exceeds a certain critical value. This critical effective temperature depends on the stellar luminosity and mass, the water abundance in the disk, and the yield of photodesorption. We present an approximate analytic formula for the critical temperature. We separate Herbig Ae/Be stars into two groups on the HR diagram according to the critical temperature; one is the disks where photodesorption is effective and from which we may not find ice particles at the surface, and the other is the disks where photodesorption is not effective. We estimate the snow line position at the surface of the disk around HD142527 to be 100--300 AU which is consistent with the water ice detection at >140 AU in the disk. All results depend on the dust grain size by a complex way and this point requires more work in future.

Are stress-free membranes really 'tensionless'?
Creators: name: Schmid, Friederike
Publisher: name: arXiv
Year: 2012
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: In recent years it has been argued that the tension parameter driving the fluctuations of fluid membranes, differs from the imposed lateral stress, the 'frame tension'. In particular, stress-free membranes were predicted to have a residual fluctuation tension. In the present paper, this argument is reconsidered and shown to be inherently inconsistent -- in the sense that a linearized theory, the Monge model, is used to predict a nonlinear effect. Furthermore, numerical simulations of one-dimensional stiff membranes are presented which clearly demonstrate, first, that the internal 'intrinsic' stress in membranes indeed differs from the frame tension as conjectured, but second, that the fluctuations are nevertheless driven by the frame tension. With this assumption, the predictions of the Monge model agree excellently with the simulation data for stiffness and tension values spanning several orders of magnitude.

description: This deliverable reports an exhaustive state-of-the-art compilation of the most representative seismic fragility and loss estimation models for the buildings and infrastructure components in the testbeds (TBs in the following) of the TURNkey project, which are: TB1-Bucharest (Romania), TB2-Pyrenees (France), TB3-Hveragerði (Southern Iceland) and Húsavík (Northern Iceland), TB4-Patras and Aegio area (Greece), TB5-Port of Gioia Tauro (Italy), and TB6- Groningen (Netherlands). This activity is included within the Work Package 4, aimed at developing and harmonizing seismic physical vulnerability and loss estimation models for structures and infrastructure components within a rapid loss prediction framework. Within a broader context, it may be stated that the contents of this deliverable may also be extrapolated as a useful synthesis of the structural vulnerability standing for the entire European territory. In the chapter 2 of the document, a detailed list of the fragility and loss estimation models adopted for building taxonomies and infrastructure components is tabulated together with their associated publication/reference and a brief description of the corresponding work. Then, futher important information is syntesized in terms of type, structural typology, intensity measure, damage scale, and the region of applicability referring to each individual fragility/loss model under consideration. In chapter 3, in-depth information and discussion of the vulnerability and loss estimation models presented in Chapter 2 are provided for each TB. Furthermore, background exposure information is also provided. Finally, chapter 4 presents the conclusive summary of the Deliverable.

description: By direct quenching or post-annealing followed by quenching, we have successfully obtained a series of KxFe2-ySe2 samples with different properties. It is found that the samples directly quenched in the cooling process of growth show superconductivity and the one cooled with furnace is insulating even though their stoichiometries are similar. The sample cooled with furnace can be tuned from insulating to superconducting by post-annealing and then quenching. Based on the two points mentioned above, we conclude that the superconducting state in KxFe2-ySe2 is metastable, and quenching is the key point to achieve the superconducting state. The similar stoichiometries of all the non-superconducting and superconducting samples indicate that the iron valence doesn't play a decisive role in determining whether a KxFe2-ySe2 sample is superconducting. Combining with the result got in the KxFe2-ySe2 thin films prepared by molecular beam epitaxy (MBE), we argue that our superconducting sample partly corresponds to the phase without iron vacancies as evidenced by scanning tunnelling microscopy (STM) and the insulating sample mainly corresponds to the phase with the $\sqrt{5}\times\sqrt{5}$ vacancy order. Quenching may play a role of freezing the phase without iron vacancies.

Solar photosphere magnetization

description: Observations reveal that at the Sun surface, the divergence of what is measured as magnetic field is significantly non-zero. In my paper, I show that what is measured is in fact the magnetic field H, which is different from the divergence-free magnetic induction B. The difference is the magnetization M, which results from the spiral charge movement about the field. However, in the solar interior, the electron thermal velocity is 14 times larger than their escape velocity from the star gravity, and yet 6 times larger than their escape velocity from protons. Therefore electrons escape and come to accumulate in surface layers, where they are responsible for magnetization. This probably occurs in all solar-type stars.

description: We report a full (3D) micromagnetic simulation of a set of 100 ferrite (Fe$_3$O$_4$) cylindrical dots, arranged in a 10 by 10 square (planar) array of side 3.27 $μ$m, excited by an external in-plane magnetic field. The resulting power spectrum of magnetic excitations and the dynamical magnetization field at the resulting resonance modes were investigated. The absorption spectrum deviates considerably from that of a single particle reference simulation, presenting a mode-shifting and splitting effect. We found an inversion symmetry through the center of the array, in the sense that each particle and its inversion counterpart share approximately the same magnetization mode behavior. Magnonic designs aiming at synchronous or coherent tunings of spin-wave excitations at given spatially separated points within a regular square array may benefit from the new effects here described.

description: Subscriber satisfaction and maximum radio resource utilization are the pivotal criteria in communication system design. In multi-Carrier CDMA system, different paging algorithms are used for locating user within the shortest possible time and best possible utilization of radio resources. Different paging algorithms underscored different techniques based on the different purposes. However, low servicing time of sequential search and better utilization of radio resources of concurrent search can be utilized simultaneously by swapping of the algorithms. In this paper, intelligent mechanism has been developed for dynamic algorithm assignment basing on time-varying traffic demand, which is predicted by radial basis neural network; and its performance has been analyzed are based on prediction efficiency of different types of data. High prediction efficiency is observed with a good correlation coefficient (0.99) and subsequently better performance is achieved by dynamic paging algorithm assignment. This claim is substantiated by the result of proposed intelligent paging strategy.

Comparative efectiveness of neutralising monoclonal antibodies in high risk COVID‑19 patients: a Bayesian network meta‑analysis

description: The purpose of this work was to review and synthesise the evidence on the comparative efectiveness of neutralising monoclonal antibody (nMAB) therapies in individuals exposed to or infected with SARS-CoV-2 and at high risk of developing severe COVID-19. Outcomes of interest were mortality, healthcare utilisation, and safety. A rapid systematic review was undertaken to identify and synthesise relevant RCT evidence using a Bayesian Network Meta-Analysis. Relative treatment efects for individual nMABs (compared with placebo and one another) were estimated. Pooled efects for the nMAB class compared with placebo were estimated. Relative efects were combined with baseline natural history models to predict the expected risk reductions per 1000 patients treated. Eight articles investigating four nMABs (bamlanivimab, bamlanivimab/etesevimab, casirivimab/ imdevimab, sotrovimab) were identifed. All four therapies were associated with a statistically signifcant reduction in hospitalisation (70–80% reduction in relative risk; absolute reduction of 35–40 hospitalisations per 1000 patients). For mortality, ICU admission, and invasive ventilation, the risk was lower for all nMABs compared with placebo with moderate to high uncertainty due to small event numbers. Rates of serious AEs and infusion reactions were comparable between nMABs and placebo. Pairwise comparisons between nMABs were typically uncertain, with broadly comparable efcacy. In conclusion, nMABs are efective at reducing hospitalisation among infected individuals at high-risk of severe COVID-19, and are likely to reduce mortality, ICU admission, and invasive ventilation rates; the efect on these latter outcomes is more uncertain. Widespread vaccination and the emergence of nMAB-resistant variants make the generalisability of these results to current patient populations difcult.
Near doping-independent pocket area from an antinodal Fermi surface instability in underdoped high temperature superconductors

description: Fermi surface models applied to the underdoped cuprates predict the small pocket area to be strongly dependent on doping whereas quantum oscillations in YBa2Cu3O6+x find precisely the opposite to be true; seemingly at odds with the Luttinger volume. We show that such behavior can be explained by an incommensurate antinodal Fermi surface nesting-type instability; further explaining the doping-dependent superstructures seen in cuprates using scanning tunneling microscopy. We develop a Fermi surface reconstruction scheme involving orthogonal density waves in two-dimensions and show that their incommensurate behavior requires momentum-dependent coupling. A co-operative modulation of the charge and bond-strength is therefore suggested.

Dimuon results in PbPb and pp collisions in CMS
Creators: name: Sánchez, Manuel Calderón de la Barca
Publisher: name: arXiv
Year: 2011
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: The LHC offers unique opportunities for studying the properties of hot QCD matter created in Pb+Pb collisions at extreme temperatures and very low parton momentum fractions. With its high precision, large acceptance for tracking and calorimetry, and a trigger scheme that allows analysis of each minimum bias Pb+Pb event, CMS is fully equipped to measure dimuons in the high multiplicity environment of Pb+Pb collisions. Such probes are especially relevant since they are produced at early times and propagate through the medium, mapping its evolution. The capabilities of the CMS experiment to study dimuon production in pp and Pb+Pb collisions based on the 2010 LHC runs will be reviewed. CMS is able to measure primary and secondary J/psi, as well as the three Upsilon states. Quarkonia results at sqrt(s)=2.76 TeV in pp and Pb+Pb will be presented, including a tantalizing observation of suppression of the Upsilon excited states. The Z0 boson inclusive and differential measurement as a probe of the initial state will be described.

Determinants of Dividend Policy:Evidence from Ethiopian Insurance Companies
Creators: name: Getachew, Samuel
Publisher: name: Zenodo
Year: 2017

description: The purpose of this study was to examine the determinants of dividend policy in Ethiopian insurance companies. For this purpose, samples of nine Ethiopian insurance companies were selected. Ordinary Least Squares (OLS) Regression was used to examine the impact of profitability, liquidity, leverage, firm size, growth opportunity, previous year dividend and asset structure on dividend policy in the insurance sector over a period of nine years from 2007/08 to 2015/16. The empirical results of this study showed that profitability, leverage, liquidity, previous year dividend and asset structure have a positive relationship with dividend payout. Meanwhile, firm size and growth opportunities have a negative relationship with dividend payout. Furthermore, the results of the analysis indicated that profitability, liquidity, growth opportunities, previous year dividend and asset structure were the major factors that affected dividend policies of Ethiopian insurance companies and mangers of Ethiopian insurance companies need to consider these factors while setting/revising their dividend payout policy; on the same token investors need to consider these factors in their investment decisions when they want to make an investment in Ethiopian insurance companies.
