description: We study the edge-mode excitations of a fractional quantum Hall droplet by expressing the edge state wavefunctions as linear combinations of Jack polynomials with a negative parameter. We show that the exact diagonalization within subspace of Jack polynomials can be used to generate the chiral edge-mode excitation spectrum in the Laughlin phase and the Moore-Read phase with realistic Coulomb interaction. The truncation technique for the edge excitations simplifies the procedure to extract reliably the edge-mode velocities, which avoids the otherwise complicated analysis of the full spectrum that contains both edge and bulk excitations. Generalization to the Read-Rezayi state is also discussed.

description: The mechanical properties of nanostructured wires obtained by co-assembly of iron oxide particles are studied. The intrinsic magnetic properties of the wires are used to induce and quantify the bending of the one-dimensional objects. From the relationship between the deflection and the magnitude of the magnetic field, the elastic rigidity and Young modulus of the wires are determined. Young moduli in the megapascal range are obtained and are consistent with sub-piconewton force detection.

description: We present nonlinear conduction phenomena in the Mott insulator Ca2RuO4 investigated with a proper evaluation of self-heating effects. By utilizing a non-contact infrared thermometer, the sample temperature was accurately determined even in the presence of large Joule heating. We find that the resistivity continuously decreases with currents under an isothermal environment. The nonlinearity and the resulting negative differential resistance occurs at relatively low current range, incompatible with conventional mechanisms such as hot electron or impact ionization. We propose a possible current-induced gap suppression scenario, which is also discussed in non-equilibrium superconducting state or charge-ordered insulator.

description: Many of the essential features of the evolution of scientific research are imprinted in the structure of citation networks. Connections in these networks imply information about the transfer of knowledge among papers, or in other words, edges describe the impact of papers on other publications. This inherent meaning of the edges infers that citation networks can exhibit hierarchical features, that is typical of networks based on decision-making. In this paper, we investigate the hierarchical structure of citation networks consisting of papers in the same field. We find that the majority of the networks follow a universal trend towards a highly hierarchical state, and i) the various fields display differences only concerning their phase in life (distance from the "birth" of a field) or ii) the characteristic time according to which they are approaching the stationary state. We also show by a simple argument that the alterations in the behavior are related to and can be understood by the degree of specialization corresponding to the fields. Our results suggest that during the accumulation of knowledge in a given field, some papers are gradually becoming relatively more influential than most of the other papers.

description: Die vorliegende Arbeit handelt von Macht in der Sozialen Arbeit. Soziale Arbeit findet vorwiegend in Beziehungen statt, und in Beziehungen findet sich immer auch der Aspekt der Macht wieder. Obwohl das Phänomen der Macht in der Sozialen Arbeit allgegenwärtig ist, wird dem Thema teilweise zu wenig Beachtung geschenkt, auch im Kontext der professionellen Beratung der Sozialen Arbeit. In der vorliegenden Arbeit wird anhand einer Literaturrecherche und -analyse untersucht, wie in der professionellen Beratung der Sozialen Arbeit, speziell im freiwilligen Kontext, ein sensibler Umgang mit Macht in der Zusammenarbeit mit Klient*innen gefunden werden kann. Das Verständnis, die Merkmale, die Handlungsfelder, die Methodik und die Gestaltung von Beratung in der Sozialen Arbeit werden erläutert. Weiter wird sich dem Begriff der Macht mittels Definition, Abgrenzung und Machttheorien angenähert. Es wird auf die Auseinandersetzung mit Macht in der Beratung eingegangen, insbesondere auf Methoden und Instrumente zur Machtanalyse und Reflexion über Machtaspekte, sowie Möglichkeiten zur machtsensiblen Gestaltung von Gesprächen. Die Autorinnen kommen zum Schluss, dass Sozialarbeitende einen bewussten Umgang mit Macht finden sollten. Es wird aufgezeigt, wie sich Professionelle mit der eigenen Machtbiografie auseinandersetzen können. Gezeigt wird auch, wie organisationale Strukturen kritisch hinterfragt und ein Dialog zum Thema Macht im Arbeitsteam angestossen werden kann. Die vorliegende Arbeit beinhaltet zusätzlich Handlungsempfehlungen für die Beratungspraxis in Bezug auf Machtaspekte.

description: A seed layer-free growth of HfO$_2$ on commercially available CVD graphene from various suppliers is investigated. It is revealed that the samples of monolayer graphene transferred from Cu to SiO$_2$/Si substrates have different coverage with bi- and multi-layer graphene islands. We find that the distribution and number of such islands impact the nucleation and growth of HfO$_2$ by CVD. In particular, we show that the edges and surface of densely distributed bi-layer graphene islands provide good nucleation sites for conformal CVD HfO$_2$ layers. Dielectric constant of 16 is extracted from measurements on graphene- HfO$_2$-TiN capacitors.

description: Rate constants for the potentially important interstellar N(4S) + CH(X2Πr) reaction have been measured in a continuous supersonic flow reactor over the range 56 K < T < 296 K using the relative rate technique employing both the N(4S) + OH(X2Πi) and N(4S) + CN(X2Σ+) reactions as references. Excess concentrations of atomic nitrogen were produced by the microwave discharge method upstream of the Laval nozzle and CH and OH radicals were created by the in-situ pulsed laser photolysis of suitable precursor molecules. In parallel, quantum dynamics calculations of the title reaction have been performed based on accurate global potential energy surfaces for the 13A' and 13A" states of HCN and HNC, brought about through a hierarchical construction scheme. Both adiabatic potential energy surfaces are barrierless, each one having two deep potential wells suggesting that this reaction is dominated by a complex-forming mechanism. The experimental and theoretical work are inexcellent agreement, predicting a positive temperature dependence of the rate constant, in contrast to earlier experimental work at low temperature. The effects of the new low temperature rate constants on interstellar N2 formation are tested using a dense cloud model, yielding N2 abundances 10-20 % lower than previously predicted.

description: Several studies worldwide have shown that reproductive-aged people often have inadequate fertility awareness (FA). Since attitudes and health behaviours are influenced by the partner, there is a need for studies exploring the role of these influences on the individuals’ adoption of fertility protective behaviours (FPB). This study explores the role of FA and relationship quality on couples’ intention to adopt FPB. One hundred and twelve childless couples answered an online questionnaire about reproductive life plan, FA and intentions to adopt FPB. The results showed that couples were moderately congruent on their reproductive life plan. The female partners who reported higher female relationship quality and higher female willingness to undergo fertility treatments were more willing to adopt FPB. The male partners who had heightened FA also reported higher intention to adopt FPB. The influences of male and female FA, relationship quality and congruence on reproductive life plan were neither associated with couples’ congruence on the intention to adopt FPB. Although the cross-sectional design restricts our ability to draw causal conclusions, these findings emphasize that future interventions should be targeted at couples and designed according to their expectations and reproductive desires.

description: It is unknown whether depression and anxiety-related conditions associate with poor perinatal outcomes, especially live birth rates, among women diagnosed with recurrent pregnancy loss. We performed a retrospective cohort study using the Japanese Medical Data Centre Claims Database and identified women diagnosed with recurrent pregnancy loss. Live birth rates were compared as the primary outcome between patients with and without depression and/or anxiety-related disorders. A stabilised inverse probability of treatment weight analysis using propensity scores was also performed to assess the association. Among 5,517 eligible patients, there were 804 (14.6%) women who had depression and/or anxiety-related disorders during treatment for recurrent pregnancy loss during pregnancy. The overall live birth rates differed significantly between the groups according to the Kaplan–Meier method and log-rank test (p = 0.011). However, Cox proportional-hazards regression model and stabilised inverse probability of treatment weight analysis showed no statistically significant association between depressive disorders and live birth rates. The current study showed that approximately 15% of patients diagnosed with recurrent pregnancy loss develop depressive disorders. After accounting for variables, we found no independent association between depressive disorders after recurrent pregnancy losses and low live birth rates.

description: While there is broad evidence to suggest that individual stress increases, and that high couple relationship quality reduces the risk for psychological distress, our understanding of these associations in couples dealing with infertility remains limited. In this cross-sectional study, we used dyadic data-analysis (Actor-Partner Interdependence Model; APIM) to examine the effects of infertility-related distress (experienced as an individual risk factor) and couple relationship quality (experienced as a couple-based resource), on psychological distress in a sample of 116 infertile couples. 59% of women and 23% of men reported clinical levels of psychological distress, 71% of women and 45% of men reported infertility-related distress, and 3% of participants reported low couple relationship quality. Infertility-related distress predicted psychological distress at the individual level (‘actor effects’) while men’s infertility-related distress predicted women’s psychological distress (partner effect’). Women without medically assisted reproduction (MAR) treatment exposure reported significantly higher couple relationship quality than women with MAR exposure, and men without treatment exposure reported significantly lower infertility-related distress than men with exposure. The level of psychological distress depended on whether both or neither of the partners, or only one partner reported infertility-related distress. Couple relationship quality was not associated with distress, which may imply that dyadic dimensions other than overall satisfaction could be relevant in supporting couples facing infertility.

We specialise our formula to connective K-theory providing a geometric interpretation to the double beta-polynomials of Fomin and Kirillov by computing the fundamental classes of Schubert varieties. As a corollary we obtain a Thom-Porteous formula generalising those of the Chow ring and of the Grothendieck ring of vector bundles.

description: We present rigorous topological order which emerges in a one-dimensional spin-orbital model due to the ring topology. Although an exact solution of a spin-orbital ring with SU(2) spin and XY orbital interactions separates spins from orbitals by means of a unitary transformation, the spins are not independent when the ring is closed, but form two half-rings carrying opposite pseudomomenta. We show that an inverse transformation back to the physical degrees of freedom entangles the spin half-rings with the orbitals once again. This surprising correlation arises on changing the topology from an open to a closed chain, which reduces the degeneracy of the ground-state manifold, leaving in it only the states in which pseudomomenta compensate each other.

description: We aim to identify the birth place of the young pulsar PSR J0826+2637 in order to determine its kinematic age and give constraints on its radial and spatial (kick) velocity. Since the majority of neutron star (NS) progenitors are in associations or clusters, we search for a possible origin of the NS inside such stellar groups. We trace back the NS and the centres of possible birth associations and clusters to find close encounters. The kinematic age is then given by the time since the encounter. We use Monte Carlo simulations to account for observational uncertainties and the unknown radial velocity of the NS. We evaluate the outcome statistically. In order to find further indication for our findings, we also search for a runaway star that could be the former companion if it exists. We find that PSR J0826+2637 was probably born in the small young cluster Stock 7 ~3 Myr ago. This result is supported by the identification of the former companion candidate HIP 13962 (runaway star with spectral type G0Ia). The scenario predicts a near-zero radial velocity of the pulsar implying an inclination angle of its motion to the line-of-sight of 87+/-11 deg. We also present the chemical abundances of HIP 13962. We do not find enhanced alpha element abundances in the highly evolved star. However, the binary supernova scenario may be supported by the overabundance of r-process elements that could have been ejected during the supernova and accreted by the runaway star. Also, a high rotational velocity of v sin i ~29 km/s of HIP 13962 is consistent with evolution in a pre-SN binary system.

Accretion, Ablation and Propeller Evolution in Close Millisecond Pulsar Binary Systems

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: A model for the formation and evolution of binary millisecond radio pulsars in systems with low mass companions (< 0.1 Msun) is investigated using a binary population synthesis technique. Taking into account the non conservative evolution of the system due to mass loss from an accretion disk as a result of propeller action and from the companion via ablation by the pulsar, the transition from the accretion powered to rotation powered phase is investigated. It is shown that the operation of the propeller and ablation mechanisms can be responsible for the formation and evolution of black widow millisecond pulsar systems from the low mass X-ray binary phase at an orbital period of ~0.1 day. For a range of population synthesis input parameters, the results reveal that a population of black widow millisecond pulsars characterized by orbital periods as long as ~0.4 days and companion masses as low as ~0.005 Msun can be produced. The orbital periods and minimum companion mass of this radio millisecond pulsar population critically depend on the thermal bloating of the semi-degenerate hydrogen mass losing component, with longer orbital periods for a greater degree of bloating. Provided that the radius of the companion is increased by about a factor of 2 relative to a fully degenerate, zero temperature configuration, an approximate agreement between observed long orbital periods and theoretical modeling of hydrogen rich donors can be achieved. We find no discrepancy between the estimated birth rates for LMXBs and black widow systems, which on average are $\sim~1.3\times10^{-5} {\rm yr}^{-1}$ and $1.3\times10^{-7} {\rm yr}^{-1}$ respectively.

On the computation of moist-air specific thermal enthalpy

description: The specific thermal enthalpy of a moist-air parcel is defined analytically following a method in which specific moist entropy is derived from the Third Law of thermodynamics. Specific thermal enthalpy is computed by integrating specific heat content with respect to absolute temperature and including the impacts of various latent heats (i.e., solid condensation, sublimation, melting, and evaporation). It is assumed that thermal enthalpies can be set to zero at $0$ K for the solid form of the main chemically inactive components of the atmosphere (solid-$α$ oxygen and nitrogen, hexagonal ice). The moist thermal enthalpy is compared to already existing formulations of moist static energy (MSE). It is shown that the differences between thermal enthalpy and the thermal part of MSE may be quite large. This prevents the use of MSE to evaluate the enthalpy budget of a moist atmosphere accurately, a situation that is particularly true when dry-air and cloud parcels mix because of entrainment/detrainment processes along the edges of cloud. Other differences are observed when MSE or moist-air thermal enthalpy is plotted on a psychrometric diagram or when vertical profiles of surface deficit are plotted.

SELF-CARE BEHAVIOR AND ASSOCIATED FACTORS AMONG CANCER PATIENTS WHO ARE ON CHEMOTHERAPY TREATMENT AT TIKUR ANBESA SPECIALIZED HOSPITAL
Creators: name: TSIGE GEBRE
Publisher: name: Zenodo
Year: 2018

description: Background: Cancer affects millions of people in the world each year, leading many to face

the difficult road of chemotherapy. When cancer patients are ill-prepared for chemotherapy

treatments, they often tend to envision the worst-case scenarios, possibly making the

anticipation more difficult than the event itself. In Ethiopia evidence on self-care behavior on

chemotherapy and associated factors is limited. So this study is aimed to fill the gap.

Objectives: To assess self-care behavior and associated factors among cancer patients who

are on chemotherapy treatment at Tikur Anbessa Specialized Hospital Addis Ababa, Ethiopia

2018. Methods: Institution based cross-sectional study design was conducted on sample

study of 254 study participants at Tikur Anbessa Specialized Hospital using simple random

sampling techniques. Face to face interview with structured questionnaire was used to collect

data. Prior to data collection 5% pretest was done to ensure the quality of data. Data was

entered in to EpI –data version 4.2 and exported into SPSS versions 24 for analysis.

Descriptive statistics used to describe the study participants with major independent and

dependent variables’ including frequencies, proportion, mean and standard deviation was

demonstrated by using tables, graphs and texts. Bivariate and multivariate logistic regression

was used to look for association between predictors and dependent variable. Crude and

adjusted odds ratios with the corresponding 95% confidence intervals were computed

description: Recently, Yao et al. demonstrated the creation of coherent emissions in nitrogen gas with two-color (800 nm + 400 nm) ultrafast laser pulses [New J. Phys. 15, 023046 (2013)]. Based on this two-color scheme, here we report on systematic investigation of temporal characteristics of the coherent emission at 391 nm by experimentally examining its evolution with the increase of the plasma channel induced by the intense 800 nm femtosecond laser pulses at a nitrogen gas pressure of ~25 mbar. We reveal unexpected temporal profiles of the coherent emissions, which show significant superradiance signatures owing to the quantum coherence via cooperation of an ensemble of excited N2+ molecules. Our findings shed more light on the mechanisms behind the laser-like emissions induced by strong-field ionization of molecules.

description: The ice-albedo feedback is a potentially important de-stabilizing effect for the climate of terrestrial planets. It is based on the positive feedback between decreasing surface temperatures, an increase of snow and ice cover and an associated increase in planetary albedo, which then further decreases surface temperature. A recent study shows that for M stars, the strength of the ice-albedo feedback is reduced This study investigates the influence of the atmosphere (in terms of surface pressure and atmospheric composition) for this feedback. A plane-parallel radiative transfer model is used for the calculation of planetary albedos. We varied CO2 partial pressures as well as the H2O, CH4, and O3 content in the atmosphere for planets orbiting Sun-like and M-type stars. Results suggest that for planets around M stars, the ice-albedo effect is significantly reduced, compared to planets around Sun-like stars. Including the effects of an atmosphere further suppresses the sensitivity to the ice-albedo effect. Atmospheric key properties such as surface pressure, but also the abundance of radiative trace gases can considerably change the strength of the ice-albedo feedback. For dense CO2 atmospheres of the order of a few to tens of bar, atmospheric rather than surface properties begin to dominate the planetary radiation budget. At high CO2 pressures, the ice-albedo feedback is strongly reduced for planets around M stars. The presence of trace amounts of H2O and CH4 in the atmosphere also weakens the ice-albedo effect for both stellar types considered. For planets around Sun-like stars, O3 could also lead to a very strong decrease of the ice-albedo feedback at high CO2 pressures. (abridged)

description: We obtain an approximate solution $\tilde{E}=\tilde{E}(e,M)$ of Kepler's equation $E-e\sin(E)=M$ for any $e\in[0,1)$ and $M\in[0,π]$. Our solution is guaranteed, via Smale's $α$-theory, to converge to the actual solution $E$ through Newton's method at quadratic speed, i.e. the $n$-th iteration produces a value $E_n$ such that $|E_n-E|\leq (\frac12)^{2^n-1}|\tilde{E}-E|$. The formula provided for $\tilde{E}$ is a piecewise rational function with conditions defined by polynomial inequalities, except for a small region near $e=1$ and $M=0$, where a single cubic root is used. We also show that the root operation is unavoidable, by proving that no approximate solution can be computed in the entire region $[0,1)\times[0,π]$ if only rational functions are allowed in each branch.

description: We show how the Landau-Ginzburg/Calabi-Yau correspondence for the quintic three-fold can be cast into a global mirror symmetry framework. Then we draw inspiration from Berglund-Hübsch mirror duality construction to provide an analogue conjectural picture featuring all Calabi-Yau hypersurfaces within weighted projective spaces and certain quotients by finite abelian group actions.

description: We present new wide-field observations of Centaurus A (Cen A) and the surrounding region at 118 MHz with the Murchison Widefield Array (MWA) 32-tile prototype, with which we investigate the spectral-index distribution of Cen A's giant radio lobes. We compare our images to 1.4 GHz maps of Cen A and compute spectral indices using temperature-temperature plots and spectral tomography. We find that the morphologies at 118 MHz and 1.4 GHz match very closely apart from an extra peak in the southern lobe at 118 MHz, which provides tentative evidence for the existence of a southern counterpart to the northern middle lobe of Cen A. Our spatially-averaged spectral indices for both the northern and southern lobes are consistent with previous analyses, however we find significant spatial variation of the spectra across the extent of each lobe. Both the spectral-index distribution and the morphology at low radio frequencies support a scenario of multiple outbursts of activity from the central engine. Our results are consistent with inverse-Compton modelling of radio and gamma-ray data that supports a value for the lobe age of between 10 and 80 Myr.

description: Hypergraph partitioning is a key algorithmic step in many domains including VLSI design, linear algebra, Boolean satisfiability, and data mining. In this work, we present BiPart, the first deterministic, parallel hypergraph partitioner which is part of the Galois system. Experimental results show that BiPart outperforms state-of-the-art hypergraph partitioners in runtime and partition quality while generating partitions deterministically. BiPart is part of Galois system. In order to use it, you first need to build Galois. BiPart is located in: Galois/lonestar/analytics/cpu/bipart The license is under The 3-Clause BSD License
Combinatorial model for the ferroelectric domain-network formation in hexagonal manganites

description: As the result of the high-temperature improper ferroelectric transition occurring in YMnO3 and other hexagonal manganites a striking domain pattern was observed: an emergence of six domains of alternating polarization from one point in a vortex-like pattern. We derive the formation and distribution of the domain-vortex network from a combinatorial analysis based on order-parameter symmetry and lattice geometry. The analysis leads to stable vortex-like configurations of the six domain states in the basal plane perpendicular to the polarization and to fragmented vortices in planes parallel to the polarization. The predictions are debated in the light of existing experimental and theoretical work on the vortex domain state. The relation of the symmetry-determined geomet- rical defects to the topological defects proposed to describe the behavior of YMnO3 near the Curie temperature is discussed.
title: Design and control of a hybrid power system for a remote telecommunication facility in Nigeria
Creators: name: Oton, Cyprian
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: The proliferation of mobile base transceiver station sites in Nigeria comes with a growing need to address those sites' source of power. Sustainability and mitigating harmful environmental impact caused by the diesel-only method of power generation is of great concern. This thesis examines the design, optimal sizing, and control of a Hybrid Power system to replace the current diesel-only option on the site. An outdoor base station site in Agbaja, a rural settlement in Kogi State, Nigeria is used as a case study. HOMER pro is used to size the system based on the measured load and available renewable resources. The PV/Diesel/Battery configuration resulted in the least Net Present Cost (NPC), Cost of Energy (COE), and unmet energy. The system is sized as DC for better performance and elimination of multiple energy conversion experienced in the AC system. A comparison between this proposed system and the current system shows a reduction in operating expenditure (OPEX) by 75% with zero unmet energy. Each component of the system is designed and simulated in a MATLAB/Simulink environment and connected to form the whole system. The transient behaviour of the system is studied under varying solar irradiation to ascertain the stability of the power supplied to the sensitive telecommunication load. The result shows a stable power output to the load at rated voltage of 48 V. Also, a low-cost open source Internet of Things (IoT)- based Supervisory Control and Data Acquisition (SCADA) system using ESP32 and Arduino IoT Cloud for monitoring and control of the system using a widget-based dashboard is also presented. Current, voltage, temperature, and humidity sensors are programmed to measure relevant parameters of interest, and the measured Data is processed and parsed to the Arduino IoT Cloud via a Wi-Fi network communication channel. A mobile application is also deployed to aid remote monitoring and control as well. LEDs are used to implement a high temperature and low voltage control logic. The prototype used to demonstrate this only cost $88.34 USD.
