description: The performance of open-system quantum annealing is adversely affected by thermal excitations out of the ground state. While the presence of energy gaps between the ground and excited states suppresses such excitations, error correction techniques are required to ensure full scalability of quantum annealing. Quantum annealing correction (QAC) is a method that aims to improve the performance of quantum annealers when control over only the problem (final) Hamiltonian is possible, along with decoding. Building on our earlier work [S. Matsuura et al., Phys. Rev. Lett. 116, 220501 (2016)], we study QAC using analytical tools of statistical physics by considering the effects of temperature and a transverse field on the penalty qubits in the ferromagnetic $p$-body infinite-range transverse-field Ising model. We analyze the effect of QAC on second ($p=2$) and first ($p\geq 3$) order phase transitions, and construct the phase diagram as a function of temperature and penalty strength. Our analysis reveals that for sufficiently low temperatures and in the absence of a transverse field on the penalty qubit, QAC breaks up a single, large free energy barrier into multiple smaller ones. We find theoretical evidence for an optimal penalty strength in the case of a transverse field on the penalty qubit, a feature observed in QAC experiments. Our results provide further compelling evidence that QAC provides an advantage over unencoded quantum annealing.

Year: 2017

description: Background; unsafe abortion in Ethiopia has long been recognized as among a leading cause of deaths and injuries to women. However there is limited scientific information available on the women who seek unsafe abortion, factors which may be a cause for unsafe abortion. Objectives; The objective was to assess the prevalence of unsafe abortion and associated risk factors among women attending maternal and child health units in public health centers in Addis Ababa. Methods; Institution based cross sectional study design was employed among 422 women attending maternal and child health unit of selected health centres between September to October 2016 in Addis Ababa A structured interviewer administered questionnaire was used. The collected data was entered using Epi data 3.0 and analyzed using IBM Statistical Package for Social Sciences version 20.0. Descriptive statistics was used to describe the study variables. Logistic regression analysis was used to assess the relative effect of determinants. A P<0.05 was considered statistically significant. Results; About 422 women invited to participate and asked for consent. About 20 excluded due to incomplete responses and refusal yielding 95.3% response rate. Among who have ever been pregnant (279), about 114(31%) had abortions in their life, of these, unsafe abortion was reported by 30 women (26%). Regarding the independent predictors, those who have completed primary education and above were about 10 times less likely in comparison with those women whose educational status was below primary level, in comparison with those women who replied abortion is legal, those who said it is allowed only in some cases were about 7 times more likely and those who replied not sure about its legalization were more than 8 times more likely , compared with those women who have no live child currently; those mothers who have more than 3 children and1- 2 children were about ninety seven and twelve times more likely to have unsafe abortion. Conclusion; Unsafe abortion is found to be high in Addis Ababa. Factors which include maternal educational status, knowledge regarding the legalization status of abortion in Ethiopia, number of pregnancy and number of live children were found to be determinants of unsafe abortion. Hence, health education regarding unwanted pregnancy, disseminating information regarding the legal status of abortion as well as educating women is recommended. Key words; unsafe abortion, prevalence, risk factors

description: In a DC point-to-plane corona discharge reactor, the mono filamentary streamers cross the inter electrode gap with a natural repetition frequency of some tens of kHz. The discharge phase (including the primary and the secondary streamers development) lasts only some hundred of nanoseconds while the post-discharge phases occurring between two successive discharge phases last some tens of microseconds. From the point of view of chemical activation, the discharge phases create radical and excited species located inside the very thin discharge filaments while during the post-discharge phases these radical and excited species induce a chemical kinetics that diffuse in a part of the reactor volume. From the point of view of hydrodynamics activation, the discharge phases induce thermal shock waves and the storage of vibrational energy which relaxes into thermal form only during the post-discharge phase. Furthermore, the glow corona discharges that persist during the post-discharge phases induce the so called electrical wind. In the present work, the post-discharge phase is simulated in a bi-dimensional geometry using the commercial FLUENT software. The discharges effects (radical and excited species creation and thermal relaxation) are involved through chemical and energy source terms calculated from a complete 2Drz streamer model already developed.

description: Nel corso della sua carriera, Luce Irigaray ha avuto un rapporto tumultuoso ma duraturo con la filosofia di Hegel, di cui si trova traccia in tutta la sua opera. Per Irigaray il confronto critico con Hegel è un imperativo legato alla necessità di liberare la cultura dal dominio maschile; questa reinterpretazione si condensa nella figura dell'eroina sofoclea Antigone. Il corpo di Antigone - sepolto vivo - rappresenta non solo il prezzo dell'amore, ma anche l'irruzione, sulla scena pubblica, di un Soggetto che normalmente viene cancellato. Antigone rappresenta il subalterno, l'ultimo, il dimenticato; Irigaray e Weil, altra autrice centrale nel percorso di rilettura qui proposto, cercano di dare spazio e voce a queste esistenze cancellate.

Throughout her career, Luce Irigaray has had a tumultuous but enduring relationship with Hegel’s philosophy, evidence of which is present in all her work. Irigaray sees the critical comparison with Hegel as an imperative tied to the necessity of liberating culture from male dominance; this reinterpretation is condensed in the figure of the Sophoclean heroine Antigone. Antigone’s body – buried alive – represents not only the price of love, but also the irruption, on the public scene, of a Subject that is, normally, erased. Antigone represents the subordinate, the last, the forgotten; Irigaray and Weil, another central author in the reinterpretation path proposed here, try to give space and voice to these cancelled existences.

Stress in der Sozialarbeit ‐ Ursachen und Folgen: Handlungsansätze zur Stressprävention anhand der sieben Säulen der Resilienz

Publisher: name: Zenodo
Year: 2023

description: Personalabbau, Reduktion der Kosten, hoher Erfolgsdruck, Konkurrenzdenken, ständige Erreichbarkeit und konstante Flexibilität sind nur einige Auswirkungen des vorherrschenden Arbeitsmarktes in der Schweiz. Die damit verbundenen stressbedingten Krankheiten steigen jedes Jahr stetig an. Mit diesen steigenden Krankheitsfällen steigt entsprechend auch die Zahl der Sozialarbeitenden, welche aus gesundheitlichen Gründen vom Arbeitsplatz fernbleiben oder gar ein Burnout erleiden. Die Sozialarbeit gehört zu jenen Berufen, welche einer Vielzahl von Risikofaktoren ausgesetzt sind. Das Entstehen von Stress wird unter bestimmten Bedingungen begünstigt, ausgelöst oder verschlimmert. Und der hektische Alltag, die Herausforderungen der Arbeit und die vielen anderen zu bewältigenden Aufgaben, die Sozialarbeitende Tag täglich zu erledigen haben, führen einige von ihnen an den Rand ihrer Kräfte. Sie sind demnach negativem Stress und dessen unzähligen Folgen ausgesetzt. Dabei ist die Art und Weise wie Menschen Stress wahrnehmen sehr unterschiedlich und hängt von den verschiedensten Faktoren ab. Die Resilienzförderung setzt sich seit Jahren mit der Thematik auseinander, dass ausreichende und verfügbare Bewältigungsstrategien den Umgang mit belastenden Situationen vereinfachen können, die Präventionsforschung mit dem Zuvorkommen der Entstehung von Krankheiten. Es stellt sich in dieser Konstellation die Frage, ob und mittels welcher Möglichkeiten Sozialarbeiter*innen ihre Resilienz stärken können, um gezielt Einfluss auf die Gesundheit, das Stressempfinden und das Wohlbefinden von zu nehmen.

description: We analyze the simulation of Dirac neutrino oscillations using quantum walks, both in vacuum and in matter. We show that this simulation, in the continuum limit, reproduces a set of coupled Dirac equations that describe neutrino flavor oscillations, and we make use of this to establish a connection with neutrino phenomenology, thus allowing to fix the parameters of the simulation for a given neutrino experiment. We also analyze how matter effects for neutrino propagation can be simulated in the quantum walk. In this way, important features, such as the MSW effect, can be incorporated. Thus, the simulation of neutrino oscillations with the help of quantum walks might be useful to explore these effects in extreme conditions, such as the solar interior or supernovae, in a complementary way to existing experiments.

Student perspectives on pre-departure orientation in study abroad: a mixed methods analysis
Creators: name: Sandberg, Anna R.
Publisher: name: No Publisher Supplied
Year: 2022

description: Study abroad is an increasingly popular component of higher education, thought to promote global citizenship ideals, including the cultural and linguistic competence needed to succeed in a globalized world. While much research has focused on student learning outcomes, scholars have discovered that simply living and studying abroad is not a guarantee for expected language and cultural learning. One possible reason for these less-than-expected learning outcomes is students’ lack of preparation for studying abroad. While several researchers have suggested changes to pre-departure preparation, few studies have analyzed current study abroad pre-departure orientation practices at US institutions or student perceptions of current programming. Using a mixed methods design, this study explores study abroad participants’ reflections on their pre-departure preparation and their perception of its impact on their study abroad experiences. The intention of this information is to help create pre-departure orientation programming based on and driven by student voices. Guiding this study are the following research questions: 1) What do students say about their preparation for their study abroad experience?, 2) Which factors of pre-departure preparation, student characteristics, or program components are associated with students’ language and cultural learning outcomes?, and 3) What do students report would have helped them improve their learning before, during, and after their study abroad experience?Data analysis revealed three major themes: 1) pre-departure orientation leaders, specifically program faculty and former study abroad students, play an important role in helping students feel prepared for studying abroad; 2) the prioritization of logistical and practical information over cultural and communication content in pre-departure orientation leaves students less prepared for the often challenging cross-cultural and -linguistic encounters that are part of an experience abroad; and 3) the one-size-fits-all approach to pre-departure orientation does not adequately address students’ individual needs, backgrounds, and identities in a way that best prepares them for studying abroad. The implications of these findings indicate that a more individualized pre-departure orientation that intentionally prepares students for culture shock and disequilibrium abroad may be necessary for students to make the most of pre-departure preparation and their experiences abroad.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: The study of the effects of friction modifiers in wheel/rail contact is vital factor for the railway networks to examine and identify property of friction modifiers on adhesion, wear rates, etc. This work focused on the effects of sand particle sizes in wheel and rail contact. The laboratory investigations were carried out on the influence of sand particle sizes in between the wheel/rail interaction by using twin disc machine. The influence of sand was investigated by using four different sand particle size distributions to account the effect. The investigation results showed that sand with higher particle sizes yield a higher adhesion coefficient but higher wear rates and surface roughness. Adhesion coefficient value increased with the increase in slip with all sand particle size distributions

description: The study aimed to evaluate the effectiveness of warehouse management in Save the Children Gambella Emergency Office. The study is a descriptive type which utilized quantitative and qualitative data. Both primary and secondary data were collected for this study. Primary data were collected with questionnaires, semi-structured interview and observation. As the number of employees in the office is below 100, the researcher of the study included the whole population in the study. A total of 77 questionnaires were distributed to employees and thanks to their collegial support, 74 of it were filled and returned. Frequency tables, percentages, mean and standard deviation were used to analyze the data with the application of SPSS 21. The finding of the study showed that Save the Children Gambella Emergency Office have major gaps in inventory control, materials handling, record keeping and application of information technology for warehouse services. The quality inspection practices of the warehouse have shown relatively higher rating than the other four factors mentioned above.

description: We present an analysis of a deep (1$σ$=13 $μ$Jy) cosmological 1.2-mm continuum map based on ASPECS, the ALMA Spectroscopic Survey in the Hubble Ultra Deep Field. In the 1 arcmin$^2$ covered by ASPECS we detect nine sources at $>3.5σ$ significance at 1.2-mm. Our ALMA--selected sample has a median redshift of $z=1.6\pm0.4$, with only one galaxy detected at z$>$2 within the survey area. This value is significantly lower than that found in millimeter samples selected at a higher flux density cut-off and similar frequencies. Most galaxies have specific star formation rates similar to that of main sequence galaxies at the same epoch, and we find median values of stellar mass and star formation rates of $4.0\times10^{10}\ M_\odot$ and $\sim40~M_\odot$ yr$^{-1}$, respectively. Using the dust emission as a tracer for the ISM mass, we derive depletion times that are typically longer than 300 Myr, and we find molecular gas fractions ranging from $\sim$0.1 to 1.0. As noted by previous studies, these values are lower than using CO--based ISM estimates by a factor $\sim$2. The 1\,mm number counts (corrected for fidelity and completeness) are in agreement with previous studies that were typically restricted to brighter sources. With our individual detections only, we recover $55\pm4\%$ of the extragalactic background light (EBL) at 1.2 mm measured by the Planck satellite, and we recover $80\pm7\%$ of this EBL if we include the bright end of the number counts and additional detections from stacking. The stacked contribution is dominated by galaxies at $z\sim1-2$, with stellar masses of (1-3)$\times$10$^{10}$ M$_\odot$. For the first time, we are able to characterize the population of galaxies that dominate the EBL at 1.2 mm.

description: We present a novel propositional proof tracing format that eliminates complex processing, thus enabling efficient (formal) proof checking. The benefits of this format are demonstrated by implementing a proof checker in C, which outperforms a state-of-the-art checker by two orders of magnitude. We then formalize the theory underlying propositional proof checking in Coq, and extract a correct-by-construction proof checker for our format from the formalization. An empirical evaluation using 280 unsatisfiable instances from the 2015 and 2016 SAT competitions shows that this certified checker usually performs comparably to a state-of-the-art non-certified proof checker. Using this format, we formally verify the recent 200 TB proof of the Boolean Pythagorean Triples conjecture.

description: We present a Mass-Luminosity Relation (MLR) for red dwarfs spanning a range of masses from 0.62 Msun to the end of the stellar main sequence at 0.08 Msun. The relation is based on 47 stars for which dynamical masses have been determined, primarily using astrometric data from Fine Guidance Sensors (FGS) 3 and 1r, white-light interferometers on the Hubble Space Telescope (HST), and radial velocity data from McDonald Observatory. For our HST/FGS sample of 15 binaries component mass errors range from 0.4% to 4.0% with a median error of 1.8%. With these and masses from other sources, we construct a V-band MLR for the lower main sequence with 47 stars, and a K-band MLR with 45 stars with fit residuals half of those of the V-band. We use GJ 831 AB as an analysis example, obtaining an absolute trigonometric parallax, pi_abs = 125.3 +/- 0.3 milliseconds of arc, with orbital elements yielding MA = 0.270 +/- 0.004 Msun and MB = 0.145 +/- 0.002 Msun. The mass precision rivals that derived for eclipsing binaries. A remaining major task is the interpretation of the intrinsic cosmic scatter in the observed MLR for low mass stars in terms of physical effects. In the meantime, useful mass values can be estimated from the MLR for the ubiquitous red dwarfs that account for 75% of all stars, with applications ranging from the characterization of exoplanet host stars to the contribution of red dwarfs to the mass of the Universe.

description: A population of quasars at z ~ 2 is determined based on dust luminosities vLv(7.8 um) that includes unobscured, partially obscured, and obscured quasars. Quasars are classified by the ratio vLv(0.25 um)/vLv(7.8 um) = UV/IR, assumed to measure obscuration of UV luminosity by the dust which produces IR luminosity. Quasar counts at rest frame 7.8 um are determined for quasars in the Bootes field of the NOAO Deep Wide Field Survey using 24 um sources with optical redshifts from the AGN and Galaxy Evolution Survey (AGES) or infrared redshifts from the Spitzer Infrared Spectrograph. Spectral energy distributions are extended to far infrared wavelengths using observations from the Herschel Space Observatory Spectral and Photometric Imaging Receiver (SPIRE), and new SPIRE photometry is presented for 77 high redshift quasars from the Sloan Digital Sky Survey. It is found that unobscured and obscured quasars have similar space densities at rest frame 7.8 um, but the ratio Lv(100 um)/Lv(7.8 um) is about three times higher for obscured quasars compared to unobscured, so that far infrared or submm discoveries are dominated by obscured quasars. Quasar source counts for these samples are determined for comparison to the number of submm sources that have been discovered with the SCUBA-2 camera at z ~ 2 using the Lv(100 um)/Lv(7.8 um) results together with the Bootes 7.8 um counts, and we find that only ~ 5% of high redshift submm sources are quasars, including even the most obscured quasars. Illustrative source counts are predicted to z = 10, and we show that existing SCUBA-2 850 um surveys or 2 mm surveys with the Goddard-IRAM Superconducting 2 Millimeter Observer (GISMO) survey camera should already have detected sources at z ~ 10 if quasar and starburst luminosity functions remain the same from z = 2 until z = 10.

Knowledge, Attitude and Practice Towards Testicular Self Examination Among Regular Undergraduate Non-Health Sciences University Students, Debre Tabor, Amhara Regional State, North West Ethiopia
Creators: name: Zeleke, Shegaw
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: Testicular self-examination is a screening technique that involves inspection and palpation of the testes for early detection of testicular cancer. The incidence of testicular cancer among 15-35 aged males have been increased worldwide despite being rare in the general population. A significant number of adult men presented with advanced stage of testicular cancer due to lack of information, knowledge and awareness of early detection measurements. Despite of increasement, nine out of ten testicular cancer cases can be detected by testicular self- examination and almost 90% can be cured if earlier detected. Objective: To assess knowledge, attitude and practice of Testicular-self-examination and associated factors among non- health sciences Debre Tabor University undergraduate regular students, North West Ethiopia,2017 Methods: An institution based cross - sectional quantitative study among 422 Debretabor University students was done. Study participants were stratified based on their year and field of study and selected by simple random sampling method. Pretested structured self-administered questionnaire on March 13/2017 was applied. The data was entered using Epi data version 3.1statistical software and analyzed using statistical package for social sciences version 22.0. Univariate, bivariate and multivariate analyses were carried out. Results: A total of 422 respondents were participated with a response rate of 415(98.3%). Out of the respondents 132 (31.8%) had good knowledge, half 213(51.3%) of respondents had favorable attitude and 49 (11.8%) had good practice. The major reason 227(62.0%) for not to perform testicular self- examination was not having knowledge about testicular self- examination. Family history of testicular cancer and cues to action were the predictor for knowledge, religion and self- efficacy were predictor for attitude and history of testicular cancer and self-efficacy were predictor for practice of testicular self- examination at P < 0.05. Conclusion and recommendations: Testicular self- examination knowledge and practice among respondents were inadequate due to lack of health promotion for testicular self- examination, but their attitude towards TSE was optimal. Debre Tabor University needs to organize workshops, seminar and conference to educate students on knowledge, attitude and practice of TSE. Ministry of health also recommended to advocate early detection of TC through TSE for young adult. Key words: Testicular self-examination, knowledge, attitude, practice, student, Ethiopia

Weyl state can be hosted either by non-centrosymmetric or magnetic materials and can be of the first or the second type. Several non-centrosymmetric materials have been proposed to be type-II Weyl semimetals, but in all of them the Fermi arcs between projections of multiple Weyl points either have not been observed directly or they were hardly distinguishable from the trivial surface states which significantly hinders the practical application of these materials. Here we present experimental evidence for type-II non-centrosymmetric Weyl state in TaIrTe$_4$ where it has been predicted theoretically. We find direct correspondence between ARPES spectra and calculated electronic structure both in the bulk and the surface and clearly observe the exotic surface states which support the quasi-1D Fermi arcs connecting only four Weyl points. Remarkably, these electronic states are spin-polarized in the direction along the arcs, thus highlighting TaIrTe$_4$ as a novel material with promising application potential.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: It is well known that the fatigue failure of bolts can affect the performance of rail joint and the safety of train running. In this work, the influences of the bolt geometry and bolt material on the stress of the rail joint are studied by Finite Element method. A three -dimensional finite element model for rail joint is developed and wheel load is applied to identify the stress of the rail joint. Different components of the rail joint bolts are being created separately and assemble in CATIA. The model consists of assembly of the rail, joint bars, bolts, nuts, washers, and wheel. A three -dimensional finite element analysis of rail joint bars is carried out in ANSYS after importing from CATIA. The wheel load and velocity are being applied to identify the stress in the rail joint. The material properties of the rail and wheel are assumed to be same. The material properties of the wheel and rail are considered to be bilinear kinematic hardening in ANSYS. All the material properties and boundary conditions are being applied strictly as per the data available by the Ethiopian railway corporation The results indicate that increasing the radius of rounded root rail bolt can reduce the stress concentration at the root of rail bolt and rail joint this will improves the fatigue strength and the working life of the rail bolt and rail joint. And changing the bolt material has an effect to the stress of the bolt.

description: Low-temperature ($T$) thermodynamic properties in magnetic fields ($B$) of the quasi-Kagome antiferromagnet CePdAl ($T_{\rm N}\sim$ 2.7 K) were studied by means of magnetization and specific-heat $C(T,B)$ measurements. The unusual magnetic phase diagram, including three thermodynamic phases I-III, and crossover anomalies, has been obtained. In low-field phase I, the existence of the partial Kondo screening state on the one-third Ce sites is supported from the thermodynamic point of view: (i) an appearance of the paramagnetic moment with one-third of the full moment around 3 T, and (ii) an occurrence of the entropy release $\sim$0.3$R$ln2 around the observed crossover. On the other hand, a strong enhancement of $C/T$ is found around the point, where $T_{\rm N}(B)$ meets the boundary of phase III, indicating the possible presence of a tri-critical point. Furthermore, it is suggested that the three metamagnetic transitions at $B_{{\rm m}i}$ ($i=$1,2,3) come from successive increments of the Ising-type magnetic moment along the $c$-axis. In high-field state above 20 T, the behavior of $f$ electron can be rather described by the crystal-electric-field model.

Resistive Tearing Instability in Electron-MHD: Application to Neutron Star Crusts

description: We study a resistive tearing instability developing in a system evolving through the combined effect of Hall drift in the Electron-MHD limit and Ohmic dissipation. We explore first the exponential growth of the instability in the linear case and we find the fastest growing mode, the corresponding eigenvalues and dispersion relation. The instability growth rate scales as $γ\propto B^{2/3} σ^{-1/3}$ where $B$ is the magnetic field and $σ$ the electrical conductivity. We confirm the development of the tearing resistive instability in the fully non-linear case, in a plane parallel configuration where the magnetic field polarity reverses, through simulations of systems initiating in Hall equilibrium with some superimposed perturbation. Following a transient phase, during which there is some minor rearrangement of the magnetic field, the perturbation grows exponentially. Once the instability is fully developed the magnetic field forms the characteristic islands and X-type reconnection points, where Ohmic decay is enhanced. We discuss the implications of this instability for the local magnetic field evolution in neutron stars' crusts, proposing that it can contribute to heating near the surface of the star, as suggested by models of magnetar post-burst cooling. In particular, we find that a current sheet a few meters thick, covering as little as $1\%$ of the total surface can provide $10^{42}~$erg in thermal energy within a few days. We briefly discuss applications of this instability in other systems where the Hall effect operates such as protoplanetary discs and space plasmas.

Gesund bleiben in der Sozialarbeit: Stressregulation bei Sozialarbeitenden mit Blick auf individuelle Möglichkeiten und organisationale Rahmenbedingungen

description: Martina Schlienger und Jennifer Thommen befassen sich in dieser Bachelorarbeit (Literaturarbeit) mit dem Thema «Gesund bleiben in der Sozialarbeit – Stressregulation bei Sozialarbeitenden mit Blick auf individuelle Möglichkeiten und organisationale Rahmenbedingungen». Dabei werden die Fragen, wie sich Sozialarbeitende besser vor Überbelastung schützen und wie Organisationen die Sozialarbeitenden beim Schutz vor Überbelastung unterstützen können, näher beleuchtet und beantwortet. Der Stress hat sich umgangssprachlich längst im (Arbeits-)Alltag etabliert und kann je nach Kontext Positives mit sich bringen. In der Regel wirkt sich chronischer Stress jedoch eher negativ auf die Gesundheit aus. Wie jemand mit Stress umgeht, hängt davon ab, wie viele Risikofaktoren vorhanden sind und welche Schutzfaktoren aktiviert werden. Diese können auf individueller sowie auf organisationaler Ebene verortet werden. In dieser Bachelorarbeit wird auf Themen wie das Kohärenzgefühl, die Achtsamkeit, soziale Unterstützung, Bewegung, Ernährung wie auch den Optimismus eingegangen. Dies sind einige Beispiele dafür, wie die Gesundheit eines Individuums beeinflusst werden kann. Das Betriebsklima, die Arbeitsbedingungen, Supervisionen und Weiterbildungen, Wertschätzung sowie eine gesundheitsbezogene Führung wiederum sind Möglichkeiten, welche seitens der Organisation zur Stressregulation und somit zur Gesundheit der Mitarbeitenden beitragen können. Eine mögliche Form dafür ist die Einführung eines Betrieblichen Gesundheitsmanagements [BGM], welches beide Ebenen verbindet und eine ganzheitliche Lösung anstrebt sowie Früherkennung, Prävention und Gesundheitsförderung miteinander vereint.

description: A remarkable feature of Schur functions -- the common eigenfunctions of cut-and-join operators from $W_\infty$ -- is that they factorize at the peculiar two-parametric topological locus in the space of time-variables, what is known as the hook formula for quantum dimensions of representations of $U_q(SL_N)$ and plays a big role in various applications. This factorization survives at the level of Macdonald polynomials. We look for its further generalization to {\it generalized} Macdonald polynomials (GMP), associated in the same way with the toroidal Ding-Iohara-Miki algebras, which play the central role in modern studies in Seiberg-Witten-Nekrasov theory. In the simplest case of the first-coproduct eigenfunctions, where GMP depend on just two sets of time-variables, we discover a weak factorization -- on a codimension-one slice of the topological locus, what is already a very non-trivial property, calling for proof and better understanding.

The Relationship between Gross Domestic Savings and Economic Growth in Ethiopia
Creators: name: Yabgeta, Jember
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: It is the fact that saving is one of the determinants of economic growth; especially, in developing countries. Transferring some portion of current income to the future (saving) can be considered as the source of capital stock in which it has great role in creating new investments, surging employment, rising disposable income thereby boosting production in the economy. In aggregate, these will result in economic growth. So, the main objective of this study is to examine the relationship between gross domestic saving and economic growth in Ethiopia. It also investigates whether the direction of causality runs from gross domestic saving to economic growth or vice versa. To achieve this objective, first it is necessary to test whether the variables are stationary or not. Granger causality tests were conducted using time series annual data ranged from 1974 to 2015, and the empirical result suggests that the causality runs from lnRGDS to lnRGDP in the long run in Ethiopia. However, there is no short run causality running from gross domestic saving to growth rate of economy in Ethiopia. On the other hand, there is long run causality running from growth rate of economy to gross domestic saving

description: We study the rotational motion of nano-flake ferromagnetic discs suspended in a Newtonian fluid, as a potential material owing the vortex-like magnetic configuration. Using analytical expressions for hydrodynamic, magnetic and Brownian torques, the stochastic angular momentum equation is determined in the dilute limit conditions under applied magnetic field. Results are compared against experimental ones and excellent agreement is observed. We also estimate the uncertainty in the orientation of the discs due to the Brownian torque when an external magnetic field aligns them. Interestingly, this uncertainty is roughly proportional to the ratio of thermal energy of fluid to the magnetic energy stored in the discs. Our approach can be implemented in many practical applications including biotechnology and multi-functional fluidics.
