description: We present the results of a detailed analysis of RXTE observations of class $ω$ which show an unusual state transition between high-soft and low-soft states in the microquasar GRS 1915+105. Out of about 600 pointed RXTE observations, the source was found to exhibit such state transition only on 16 occasions. An examination of the RXTE/ASM data in conjunction with the pointed observations reveals that these events appeared as a series of quasi-regular dips in two stretches of long duration (about 20 days during each occasions) when hard X-ray and radio flux were very low. The X-ray light curve and color-color diagram of the source during these observations are found to be different from any reported so far. The duration of these dips is found to be of the order of a few tens of seconds with a repetition time of a few hundred seconds. The transition between these dips and non-dips which differ in intensity by a factor of ~ 3.5, is observed to be very fast (~ a few seconds). It is observed that the low-frequency narrow QPOs are absent in the power density spectrum (PDS) of the dip and non-dip regions of class $ω$ and the PDS is a power law in 0.1 - 10 Hz frequency range. There is a remarkable similarity in the spectral and timing properties of the source during the dip and non-dip regions in these set of observations. These properties of the source are distinctly different from those seen in the observations of other classes. This indicates that the basic accretion disk structure during both dip and non-dip regions of class $ω$ is similar, but differ only in intensity. To explain these observations, we invoke a model in which the viscosity is very close to critical viscosity and the shock wave is weak or absent.

description: We measure the drag encountered by a vertically oriented rod moving across a sedimented granular bed immersed in a fluid under steady-state conditions. At low rod speeds, the presence of the fluid leads to a lower drag because of buoyancy, whereas a significantly higher drag is observed with increasing speeds. The drag as a function of depth is observed to decrease from being quadratic at low speeds to appearing more linear at higher speeds. By scaling the drag with the average weight of the grains acting on the rod, we obtain the effective friction $μ_e$ encountered over six orders of magnitude of speeds. While a constant $μ_e$ is found when the grain size, rod depth and fluid viscosity are varied at low speeds, a systematic increase is observed as the speed is increased. We analyze $μ_e$ in terms of the inertial number $I$ and viscous number $J$ to understand the relative importance of inertia and viscous forces, respectively. For sufficiently large fluid viscosities, we find that the effect of varying the speed, depth, and viscosity can be described by the empirical function $μ_e = μ_o + k J^n$, where $μ_o$ is the effective friction measured in the quasi-static limit, and $k$ and $n$ are material constants. The drag is then analyzed in terms of the effective viscosity $η_e$ and found to decrease systematically as a function of $J$. We further show that $η_e$ as a function of $J$ is directly proportional to the fluid viscosity and the $μ_e$ encountered by the rod.

description: Glitches are rare spin-up events that punctuate the smooth slow-down of the rotation of pulsars. For the Vela pulsar and PSR J0537-6910, the glitch sizes and the times between consecutive events have clear preferred scales, contrary to the handful of other pulsars with enough glitches for such a study. Moreover, PSR J0537-6910 is the only pulsar showing a strong positive correlation between the size of each glitch and the waiting time until the following one. We attempt to understand this behavior through a detailed study of the distributions and correlations of glitch properties for the eight pulsars with at least ten detected glitches. We model the distributions of glitch sizes and times between consecutive glitches for this sample and perform Monte Carlo simulations to explore two hypotheses that could explain why the correlation is so much weaker in other pulsars than in PSR J0537-6910. We confirm the above results for the Vela pulsar and PSR J0537-6910, and verify that the latter is the only pulsar with a strong correlation between glitch size and waiting time to the following glitch. For the remaining six pulsars, the waiting time distributions are best fitted by exponentials, and the size distributions either by power laws, exponentials, or log-normal functions. Some pulsars in the sample yield significant Pearson and Spearman coefficients ($r_p$ and $r_s$) for the aforementioned correlation. Moreover, for all except the Crab, both coefficients are positive. Our simulations show that the weaker correlations in pulsars other than PSR J0537$-$6910 cannot be due to missing glitches too small to be detected. We also tested the hypothesis that each pulsar may have two kinds of glitches, namely large, correlated ones and small, uncorrelated ones. We found for all pulsars that their glitches are not consistent with a pure uncorrelated population either.

description: Il rapporto di ricerca presenta i risultati della rilevazione online condotta dall'Universit� degli studi di Mo-dena e Reggio Emilia sulle condizioni di vita e di studio degli studenti nel periodo 8 aprile ? 2 maggio 2020. Alla rilevazione on line ha risposto il 20% degli studenti: un tasso di partecipazione adeguato per cogliere alcune significative differenze tra corsi di studio. L'indagine ha come obiettivo quello di superare l'emergenza Covid-19 con maggiore consapevolezza, analizzando le condizioni di vita e di studio degli studenti e cercando gli strumenti pi� utili a una didattica inclusiva e a uno studio che contribuisca a dare a ogni studente la possibilit� di procedere nel proprio percorso di studi e nel proprio percorso di vita nel migliore dei modi. Vengono presentati il questionario, gli strumenti di rilevazione e i risultati che emergono dall'analisi multivariata, sia per quel che riguarda le domande a risposte chiuse sia per le domande aperte, su cui sono state applicate tecniche di analisi testuale. Le diverse tecniche di analisi sono presentate per enfatizzare la specificit� del dataset che presenta un differente livello di variabilit� delle risposte nei diversi ambiti tematici. Il rapporto si conclude con una serie di considerazioni che offriamo alla comunit� di Uni-more per supportare la discussione su quanto abbiamo appreso e continuiamo ad apprendere grazie alla voce degli studenti. � ormai chiaro che l'uscita dall'emergenza sar� un processo graduale. Il punto di vista degli studenti, che cogliamo da questa rilevazione, sar� davvero prezioso per progettare le attivit� didattiche e i servizi agli studenti del prossimo anno, per offrire una didattica di qualit� che risponda alle diverse esigenze e ai diversi contesti di studio. Ulteriori sviluppi dell'analisi potranno riguardare altri approfondi-menti sulle specifiche modalit� di didattica (a distanza e in presenza) e sulla valutazione delle condizioni di vita e di lavoro del personale docente e tecnico-amministrativo. L'idea di fondo � quella di leggere, attraverso la lente dell'emergenza Covid-19, le dimensioni essenziali per migliorare la qualit� della didattica evidenziate dalla rilevazione empirica.

10 simple rules to run an open and inclusive project online
Creators: name: Whitaker, Kirstie
Publisher: name: Zenodo
Year: 2019

description: Abstract: There are many reasons why open source projects have difficulty attracting contributors. Current academic incentive structures are some of the strongest. Wanting to maintain a competitive advantage, too great a focus on novelty when publishing papers, and too little credit given to writing documentation and tutorials, all encourage researchers to reinvent the wheel in a closed team. Although I will discuss these barriers, my talk will focus on some challenges that are much easier to overcome. Not knowing where to start. "Imposter syndrome" and the various intersecting biases that accompany (and often underpin) it. Being unsure as to whether a project even wants any contributions. These can all be addressed with 10 simple rules. From laying out your welcome mat, through setting explicit expectations, to the graceful death of your project, these steps will will help you build and run an open and inclusive community-driven project online. (Breaking down capitalism may have to wait for another day.) Bio: Kirstie Whitaker is a research fellow at the Alan Turing Institute (London, UK) and senior research associate in the Department of Psychiatry at the University of Cambridge. Her work covers a broad range of interests and methods, but the driving principle is to improve the lives of neurodivergent people and people with mental health conditions. Dr Whitaker uses magnetic resonance imaging to study child and adolescent brain development and participatory citizen science to educate non-autistic people about how they can better support autistic friends and colleagues. She is the lead developer of "The Turing Way", an openly developed educational resource to enable more reproducible data science. Kirstie is a passionate advocate for making science "open for all" by promoting equity and inclusion for people from diverse backgrounds, and by changing the academic incentive structure to reward collaborative working.

description: We present a setup for a direct, total teleportation of a single-particle entangled state. Our scheme consists of a parametric down-conversion source, which emits a pair of entangled photons, and a dual Bell measurement system with two beam splitters and two pairs of detectors. An entangled state shared by a pair of beams can be directly transferred to another pair of beams with a 50% probability of success. By a straightforward generalization of the scheme, total teleportation of a multi-particle entangled state can also be performed.

The development of the Pergerakan Kaum Ibu UMNO, 1945-1972

Subjects: subject: Kaum Ibu UMNO
subject: Women Political activity Malaysia

description: Within traditional Malay society, its religion and its custom, women were clearly subordinate to men, their prime function the fulfilment of their roles as wives and mothers, as supporters and nurturers. Despite this prescription, they played a vital and essential role in subsistence agriculture and small commerce. Their participation in economic life provided them with avenues of influence in decision-making, but, with the exception of a few aristocratic women, this influence was generally indirect and informal. The reinstatement of British rule in Malaya following World War Two, and the subsequent involvement of Malay women as well as men in national political life, suggests a dramatic change in the role of women. They attended rallies and demonstrations; they made speeches; they joined political organisations; later they voted and sought election to public office. Concurrently, women in increasing numbers enjoyed the availability of formal schooling; a growing number moved from unpaid rural work to paid employment in the secondary and tertiary sectors of the economy. But these changes - political, educational and economic - were changes which affected most Malay men as they did women; they did not necessarily demand a change in the role of women vis-a-vis men. To what extent did change in fact occur in the role of women involved particularly in political life? Had traditional attitudes towards the role of women been replaced by new values? Or was tradition, instead, sufficiently flexible to accommodate the participation of women in a non-traditional setting, without necessitating essential changes in their role? To examine these questions, this thesis focuses on the Pergerakan Kaum Ibu UMNO, the largest women's political organisation in Malaya. The Kaum Ibu began as a number of small independent women's associations in 1945. They confederated as state organisations affiliated with the United Malays National Organisation in 1947; in 1949, they reconstituted as the women's section of the party. From 1949, this section expanded and consolidated, to become a mass women's organisation of significant political importance to the party. The section and its members appeared far removed from the women of traditional Malay society a quarter of a century earlier. However, by examining the status of the section, its interests, its activities and its attitudes to the role of women within the party and within society, the thesis argues that in fact essential change had not occurred, and that the Kaum Ibu provided a continuum from traditional life to involvement in contemporary political processes.

description: Entanglement of high dimensional states is becoming increasingly important for quantum communication and computing. The most common source of entangled photons is spontaneous parametric down conversion (SPDC), where the degree of frequency and momentum entanglement is determined by the non-linear interaction volume. Here we show that by reducing the length of a highly non-linear material to the micrometer scale it is possible to relax the longitudinal phase matching condition and reach record levels of transverse wavevector entanglement. From a micro-sized layer of lithium niobate we estimate the number of entangled angular modes to be over 1200. The entanglement is measured both directly using correlation measurements and indirectly using stimulated emission tomography. The high entanglement of the state generated can be used to massively increase the quantum information capacity of photons, but it also opens up the possibility to improve the resolution of many quantum imaging techniques.

description: ABSTRACT

 

This study aims to determine the impacts of organizational culture on innovation management in Mogadishu. Specific Objectives: Establish the relationship between Leadership Style and innovation management in Mogadishu. Determine the relationship between Work Environment and innovation management in Mogadishu. Establish the relationship between Orientation and innovation management in Mogadishu.

Research Design: The research design employs a Descriptive Design, utilizing characteristics of respondents and correlation to collect quantitative research data from a sample population. Survey research is the adopted method, focusing on quantitative information. Research Population: The research population consists of individuals working in selected organizations/companies in Mogadishu. The study focuses on the community and workforce within these institutions. Mogadishu, Banadir Somalia, was purposefully selected for its convenient location and relevance to the study elements. The study involved 80 respondents. A sample size of 67 respondents was determined through purposive and random sampling methods. This approach enhances the understanding of the research problem, ensuring a higher degree of validity, reliability, and eliminating biases.

The Statistical Package for Social Scientists (SPSS) software package was used to generate descriptive and inferential statistics. Table 4.9 indicates a moderate but positive significant correlation between Leadership Style and innovation management in Somalia, with a statistically significant result (Sig. value = .000 < .05). The findings reject the null hypothesis, concluding a statistically significant positive relationship between Leadership Style and innovation management. Table 4.15 shows a weak but significant correlation between Work Environment and innovation management in Mogadishu (Sig. value = .000 < .05), rejecting the null hypothesis and concluding a statistically significant positive relationship. Table 4.21 reveals a strong and positive significant correlation between Orientation and innovation management in Mogadishu (Sig. value = .000 < .05). The null hypothesis is rejected, indicating a statistically significant positive relationship between Orientation and innovation management. In summary, the study finds statistically significant positive relationships between Leadership Style, Work Environment, Orientation, and innovation management in Mogadishu, supporting the influence of organizational culture on innovation.

description: We study the well-posedness of the reduced Hartree-Fock model for molecules and perfect crystals when taking into account a self-generated magnetic field. We exhibit a critical value $α_c > 0$ such that, if the fine structure constant $α$ is smaller than $α_c$, then the corresponding system is stable, whereas if $α$ is greater than $α_c$, it is unstable. We give an explicit characterisation of $α_c$ as a minimisation problem over the set of zero-modes, and we prove that the critical values for the molecular case and the periodic case coincide. Finally, we prove the existence of minimisers when the system is neutral or positively charged.

description: We construct a new (singular) cohomogeneity-three metric of G_2 holonomy. The solution can be viewed as a triple intersection of smeared Taub-NUTs. The metric comprises three non-compact radial-type coordinates, with the principal orbits being a T^3 bundle over S^1. We consider an M-theory vacuum (Minkowski)_4\times M_7 where M_7 is the G_2 manifold. Upon reduction on a circle in the T^3, we obtain the intersection of a D6-brane, a Taub-NUT and a 6-brane with R-R 2-form flux. Reducing the solution instead on the base space S^1, we obtain three intersecting 6-branes all carrying R-R 2-form flux. These two configurations can be viewed as a classical flop in the type IIA string theory. After reducing on the full principal orbits and the spatial world-volume, we obtain a four-dimensional metric describing a lattice universe, in which the three non-compact coordinates of the G_2 manifold are identified with the spatial coordinates of our universe.

description: We present dynamically consistent solutions for hot accretion onto unmagnetized, rotating white dwarfs (WDs) in five quiescent dwarf novae. The measured WD rotation rates (and other system parameters) in RX And, SS Cyg, U Gem, VW Hyi and WZ Sge imply spindown of the WD by an extended hot flow emitting most of its X-rays in the vicinity of the stellar surface. In general, energy advection is absent and the flow is stable to convection and hydrodynamical outflows. In rapidly rotating systems, the X-ray luminosity provides only an upper limit on the quiescent accretion rate because of substantial stellar spindown luminosity. We suggest that the presence of hot flows in quiescent dwarf novae may limit the long-term WD rotation rates to significantly sub-Keplerian values.

description: Tolphorea turcica Platia and Gudenzi, 2000  (Figs. 2, 7)
This species was described by Platia and Gudenzi (2000) based on a female.
 Male Description. The male can be separated from the female by the shorter and narrower body; antennae exceeding posterior angles of pronotum by about 0.5 articles; pronotum slightly longer than wide and lower elytral:pronotal length ratio. The median lobe is clearly longer than the parameres (Fig. 5) and the apex is pointed; sides of parameres are sinuate, without distal teeth, and apices of parameres are slightly pointed; basal piece ‘U’ shaped. Length 3.86 mm, width 1.27 mm. In comparison to drawings of the aedeagi of Tolphorea bicolor Cate, Platia, and Schimmel, 2002 and Tolphorea volans Gurjeva, 1983 (Cate et al. 2002) and a description of the aedeagus of Tolphorea pallida Platia, 2003 (Platia 2004), male specimens of T. turcica are distinctly differentiated by the absence of distal teeth on the parameres.
 Locality Record. 1 male: Adıyaman: Gölbaşı Boruk mountain, (37°53′08″N 37°43′04″E), 1,100 m, 02.V.2008, leg. E. Yağmur. Also known from the holotype female: Adıyaman: Nemrut mountain, 1,700 m, 13–15.V.1997, leg. G. Magnani (Platia and Gudenzi 2000).

description: Contex. Stellar spectra synthesis is essential for the characterization of potential planetary hosts. In addition, comprehensive stellar variability calculations with fast radiative transfer are needed to disentangle planetary transits from stellar magnetically-driven variability. The planet-hunting space telescopes, such as CoRoT, Kepler, and TESS will bring vast quantities of data, rekindling the interest in fast calculations of the radiative transfer. Aims. We revisit the Opacity Distribution Functions (ODF) approach routinely applied to speedup stellar spectral synthesis. To achieve a considerable speedup relative to the current state-of-the-art, we further optimize the approach and search for the best ODF configuration. Furthermore, we generalize the ODF approach for fast calculations of flux in various filters often used in stellar observations. Methods. In a parameter-sweep-fashion, we generated ODF in the spectral range from UV to IR with different setups. The most accurate ODF configuration for each spectral interval was determined. For calculations of the radiative fluxes through filters we adapted the wavelength grid based on the transmission curve, whereafter the normal ODF procedure was performed. Results. Our optimum ODF configuration allows for a three fold speedup, compared to the previously used ODF configurations. The ODF generalization to calculate fluxes through filters results in a speedup of more than two orders of magnitude.

The coconut industry in Sri Lanka : an analysis of government intervention measures
Creators: name: De Silva, Hewa Willaddarege Sumiththapala
Publisher: name: The Australian National University
Year: 1979
Subjects: subject: Coconut industry Sri Lanka

description: The coconut industry occupies an important position in the economy of Sri Lanka. In addition to being a staple food item, it is the biggest land user, the third highest foreign exchange earner and an important source of government tax revenue. Since independence the government has intervened substantially in the industry, through price subsidies and trade policies such as export bans, restrictions and duties. The apparent objectives of government intervention have been to boost coconut production and productivity, protect domestic consumers, reduce price risk in production and collect government revenue. The purpose of the present study is to analyse the economic effects of these intervention policies and to evaluate alternative policies which may have more efficiently achieved the apparent objectives of the government. The analysis is preceded by a description of the Sri Lankan coconut industry and of the policies that have directly affected the industry since independence in 1948. The pure theory of trade demonstrates conclusively that, under certain assumptions, any type of interference in the free-flow of goods and services tends to reduce potential economic welfare. However, the apparent opportunities available for Sri Lanka to improve its terms of trade in desiccated coconut and edible copra through restricting exports justify some government taxation of the export of these products. Indeed if raising revenue for and providing consumer subsidies is sufficiently expensive administratively, it may well be that one could justify economically export duties beyond what would be the optimal tax level if government revenue could be raised costlessly. This is because such duties not only assist domestic consumers but also raise government revenue. There may also be some economic justification for expanding extension service and public sector investment on coconut research, especially to suit the needs of small farmers, so as to boost coconut production and productivity, In addition, to reduce the risk of export prices falling at times to very low levels, 'pot holing' assistance rather than a price stabilization scheme may be the most efficient instrument. A more precise policy analysis would be desirable, but will only be possible once more comprehensive industry data are collected.
Simultaneous Existence of Confined and Delocalized Vibrational Modes in Colloidal Quantum Dots

description: Coupling to phonon modes is a primary mechanism of excitonic dephasing and energy loss in semiconductors. However, low-energy phonons in colloidal quantum dots and their coupling to excitons are poorly understood, since their experimental signatures are weak and usually obscured by unavoidable inhomogeneous broadening of colloidal dot ensembles. We use multi-dimensional coherent spectroscopy at cryogenic temperatures to extract the homogeneous nonlinear optical response of excitons in a CdSe/CdZnS core/shell colloidal quantum dot ensemble. Comparison to simulation provides evidence that the observed lineshapes arise from the co-existence of confined and delocalized vibrational modes, both of which couple strongly to excitons in CdSe/CdZnS colloidal quantum dots.

description: This paper presents design and control of dual-switch non-inverting buck-boost converter (CBB). This converter is designed to simplify the compatibility of electronic ballast with simple and low cost LED drivers. The converter provides starting voltage and current limitation of electronic ballasts, which operates at continuous conduction mode (CCM). The voltage of load terminal is controlled by adjusting the duty cycle of the PWM regulator. Although both converter switches are controlled separately, one feedback control loop is needed to obtain the desired compensator level. Appropriate control requirements have been defined by analyzing open-loop characteristic of converter transfer function through the small-signal model of CBB, which lets decide about the control strategy and analyse the stability and performance of the closed loop control system. In order to obtain the desired output voltage, Type-III rational controller is preferred because of the non-minimum phase feature in the converter boost mode. The performance of the synthesized voltage controller is verified by comparing of the pre-determined performance requirements and the obtained simulation results.

description: We demonstrate with experiments that wrinkling in stretched latex sheets occur over finite strains, and that their amplitudes grow and then decay to zero over a greater range of applied strains compared with linear elastic materials. The wrinkles occur provided the sheet is sufficiently thin compared to its width, and only over a finite range of length-to-width ratios. We show with simulations that the Mooney-Rivlin hyperelastic model describes the observed growth and decay of the wrinkles in our experiments. The decrease of wavelength with applied tension is found to be consistent with a far-from-threshold scenario proposed by Cerda and Mahadevan in 2003. However, the amplitude is observed to decrease with increasing tensile load, in contrast with the prediction of their original model. We address the crucial assumption of {\it collapse of compressive stress}, as opposed to collapse of compressive strain, underlying the far-from-threshold analysis, and test it by measuring the actual arc-length of the stretched sheet in the transverse direction and its difference from the width of a planar projection of the wrinkled shape. Our experiments and numerical simulations indicate a complete {\it collapse of the compressive stress}, and reveal that a proper implementation of the far-from-threshold analysis is consistent with the non-monotonic dependence of the amplitude on applied tensile load observed in experiments and simulations. Thus, our work support and extend far-from-threshold analysis to the stretching problem of rectangular hyperelastic sheets.

description: Abstract

Anemia is a significant public health concern affecting pregnant women worldwide, particularly in developing regions. This study examines the prevalence of anemia among pregnant women attending antenatal care (ANC) at Bay Regional Hospital in Baidoa District, Bay Region, Somalia. The research assesses the factors contributing to anemia, including nutritional deficiencies, socioeconomic conditions, and healthcare accessibility.

Using a cross-sectional study design, data was collected through surveys and laboratory tests from pregnant women receiving ANC services. The findings reveal a high prevalence of anemia, with iron deficiency being the most common cause. The study highlights key risk factors, such as inadequate dietary intake, poor healthcare access, low socioeconomic status, and high rates of parasitic infections. Additionally, cultural beliefs and limited awareness about anemia prevention contribute to its widespread occurrence.

The study emphasizes the need for targeted interventions, including improved maternal nutrition programs, routine iron supplementation, community health education, and strengthened healthcare services. Recommendations include increasing awareness about anemia prevention, enhancing ANC services, and implementing policies to address nutritional deficiencies among pregnant women. These findings provide valuable insights for healthcare providers, policymakers, and organizations working to improve maternal and child health outcomes in Somalia.
