description: Sleep paralysis (SP) is a benign, transient episode of immobility and it lasts a few seconds toa few minutes. It can occur while falling asleep or on awakening. It is a condition of unknown etiologyand all the skeletal muscles are almost ‘paralyzed’. It leads to an inability to speak or move but individualremains conscious. This review summarizes the existential clinical literature on sleep paralysis mostrelevant to practitioners; also summarizes the many historical and artistic manifestations of SP in differentcultures. It also throws light on the available Arabic literature and others as per the aim of the review.For this review, literature search using engines was carried out, and review papers and original researcharticles were analyzed. We start with a review which summarizes the collection of symptoms, prevalencerate, risk factors and etiological theories, characteristics and classification of the SP over the past years upto the present time, also the management in the form of psychotherapy and pharmacotherapy as well asthe cultural significances in different countries. SP plays an important role in the genesis and maintenanceof many supernatural beliefs such as nocturnal alien abductions, demonic and ghost attacks in individualswith intact reality testing.

description: A large number of directors at the time of crisis tries to buy cheap or take it failed company. Many believe that they will renew the business activity and consolidate that company in the first two years. Practice shows that a very small number of directors achieve their belief into practice. The great economic crisis 2009th was suddenly slowed mergers and acquisitions. In the second half of 2010, we can see signs of recovery this organizational tool to increase corporate performance. It turned out that the weak economy, the newly-purchased company can ensure its own survival by reducing costs, which would impact on reducing the selling price, and thus to improve competitive performance. The paper aims to present the mergers and acquisitions as well as organizational modalities in transformations of different systems and organizations.
EXPLORING THE POETICS OF VOICE IN EDWIDGE DANTICAT'S THE DEW BREAKER AND THE FARMING OF BONES

description: Most critical analyses of Edwidge Danticat’s works have primarily focused on context-based theories to explore the Caribbean people's historical, cultural, psychological, and political realities. However, there has been inadequate emphasis on her narratives' artistic and textual elements, particularly the examination of recurring narratological poetics. This paper aims to investigate the narratological poetics of narration (voice) in Edwidge Danticat’s The Dew Breaker (2004) and The Farming of Bones (1998) within the corpus of Caribbean literature. Using a qualitative approach, the research seeks to demonstrate the extent and purposes of deploying classical narratological poetics of narration (voice) in selected texts. The study argues that narratology offers unique insights into deciphering narrative structures and that narratological poetics/tenets are effective tools for studying narrative techniques. The research shows that the shift from homodiegetic to heterodiegetic narration and the shifting narratorial alliances from one character to another within a heterodiegetic narration allow The Dew Breaker, and by implication narrative texts, to represent different individual consciousnesses as they recreate their experiences. This is what lends The Dew Breaker its narratorial complexity, beauty, and aesthetic dexterity. The paper also reveals that narrative levels in The Farming of Bones add different perspectives and diversity to the narrative act of the text and increase the complexity and narrative aesthetics of the text. The research further demonstrates that intradiegetic narrations have both explicative and thematic functions in The Farming of Bones. The study argues that the classical narratological poetics of narration (voice) can determine the extent to which readers are guided or manipulated in relation to any given narrative text. Overall, Danticat’s narratives’ meanings and artistic complexities are influenced by the application of narration (voice) poetics, which serves to represent Haitian/Caribbean realities

description: Community detection in networks is commonly performed using information about interactions between nodes. Recent advances have been made to incorporate multiple types of interactions, thus generalizing standard methods to multilayer networks. Often though, one can access additional information regarding individual nodes, attributes or covariates. A relevant question is thus how to properly incorporate this extra information in such frameworks. Here we develop a method that incorporates both the topology of interactions and node attributes to extract communities in multilayer networks. We propose a principled probabilistic method that does not assume any a priori correlation structure between attributes and communities but rather infers this from data. This leads to an efficient algorithmic implementation that exploits the sparsity of the dataset and can be used to perform several inference tasks; we provide an open-source implementation of the code online. We demonstrate our method on both synthetic and real-world data and compare performance with methods that do not use any attribute information. We find that including node information helps in predicting missing links or attributes. It also leads to more interpretable community structures and allows the quantification of the impact of the node attributes given in input.

description: Closed string tachyons have long been somewhat mysterious. We note that there is often a regime in the classical moduli space in which one can systematically compute the effective action for such fields. In this regime, the tachyon is light, and cannot be integrated out. Instead, one must consider the combined dynamics of gravitons, moduli, tachyons and other light fields. We compute the action and find that the quartic term for the tachyon is positive in the field definition where the tachyon has no derivative coupling to the radion. We study the evolution of isotropic, homogeneous configurations and find that typically the system is driven to regions where the calculation is no longer under control.

description: Sleep paralysis (SP) is a benign, transient episode of immobility lasting a few seconds to a few minutes that can occur whilefalling asleep or on awakening. It is a condition of unknown etiology. During the episode, all the skeletal muscles are virtually‘paralyzed’, resulting in an inability to move or speak but individual remains conscious. Because it occurs in a clear sensorium,the individual is able to describe the experience vividly. It is associated with extreme anxiety, phobia, and nervousness, restlessand, sometime, hallucinations.We present a case of 35 year old male personal driver, who had recurrent episode of sleep paralysis, we must rule outphysical, psychological or social suffering and the subject must be examined by sleep clinicians or psychiatrist. “Supernatural”experiences associated to SP have been interpreted as pathological. We must enrich the knowledge about these experiencesof SP and their psychological and cultural aspects. SP may be misdiagnosed as being due to depression and psychosis (e.g.schizophrenia) and alternatively depending on how they construe these experiences.

description: By means of the multifractal analysis (MFA), the expressions of the probability density functions (PDFs) are unified in a compact analytical formula which is valid for various quantities in turbulence. It is shown that the formula can explain precisely the experimentally observed PDFs both on log and linear scales. The PDF consists of two parts, i.e., the {\it tail} part and the {\it center} part. The structure of the tail part of the PDFs, determined mostly by the intermittency exponent, represents the intermittent large deviations that is a manifestation of the multifractal distribution of singularities in physical space due to the scale invariance of the Navier-Stokes equation for large Reynolds number. On the other hand, the structure of the center part represents small deviations violating the scale invariance due to thermal fluctuations and/or observation error.

description: Can we see (any kind of an) end to our expectations? The end should be determined by the Government’s package deal: improving solvency; increasing economic activity; stimulating export growth and domestic products purchase; maintaining employment rate; tending to the debts that are increasingly coming in. The goal is, therefore, well-known – investments should be increased, because only with their help can the development be made sustainable and with that it can reach the level achieved by comparable countries in transition. And that is what we need and what, again, opens up the story about competitiveness, about how our economy could become competitive in some near future, and of course, how it could become an exporting economy. Export should be the generator of that healthy economy growth. It would be considered a huge success if, in the next ten years we could achieve yearly growth rate of about 5%, which is important for tending to the external debt. Because if it does not achieve social product growth rate of 5% per year, Serbia could get into serious problems, and tending to the debts could become unbearable. Specifically because of that we should do everything that can be done in order to, not only boost foreign investments but also increase domestic savings, which is an important development factor everywhere in the world. However, the attractiveness of our economy to the direct foreign investments is obviously low, because of still unresolved key obstacles to their entering our economy: there still is no explicit political conviction that strategic investors have to come. So, a question is posed: Which is, in the era of financial crisis, real measure of foreign direct investments inflow, especially since the expectations are very different, from those reserved, to those that are expecting an investment boom this year. Will, for example, as was announced until recently, Telekom Serbia be sold to Deutche Telecom? Is there an interest of big german partners to enter proprietary structure of: trade, information technologies, telecommunication, energetic, car-industry and construction industry of Serbia? Surely, it would be good to take an advantage of the expressed desire of German businessmen for greater cooperation, because such solutions can bring better results for both sides.

description: Some mountain areas of southwestern Serbia have good natural conditions for cattle breeding. Nevertheless, these resources have not been exploited enough. On the other side, there is contentious problem of unemployment. Causes of this situation are the result of overall social circumstances. So far, no major efforts were taken to change this situation. However, there are several measures that are attainable for the improvement of cattle breeding in these areas.

Americans on the political left and right are engaged in a Culture War with one another, one that is often characterized by mutual fear, antipathy, and avoidance. Are there safe havens from the socially straining effects of this Culture War, times and places where Americans of different political stripes gather and put aside their political differences? Previous research (Chen & Rohla, 2018) implied that there might not be insofar as even intimate family gatherings seem to be subject to Culture War tensions. They found that politically diverse Thanksgiving Dinners were 35-70 minutes shorter than politically uniform ones, representing a 14- 27% reduction in overall dinner duration. Noting analytical and methodological limitations in the prior analysis, we conducted two pre-registered studies to test whether diverse dinners are shorter than uniform ones and to attempt to conceptually replicate and extend this prior analysis. Individual analyses yielded mixed results, with null models generally supported but effect estimates generally overlapping with those of Chen and Rohla (2018). A mega-analysis found that, when controlling for various covariates, politically diverse dinners were 24 minutes shorter than politically uniform ones, 95% confidence interval = [9, 39], representing a 6% decrease in the total dinner time [2%-10%]. This final result successfully replicates Chen and Rohla (2018) both in terms of effect overlap and direct-and-significance criteria while nonetheless favoring the conclusion that politics is not straining family ties as much as previously thought.

Analyzing the investment of public and private sectors in research and development of agricultural biotechnology, with special reference to one of the most important parameters-the number and geographic distribution of field trials, the paper points to the dominant role of the private sector. Dominance of the private sector is reflected in the total investment, the implementation of field trials, as well as the number of commercial crops.

description: We study Bragg spectroscopy of ultra-cold atoms in one-dimensional optical lattices as a method for probing the excitation spectrum in the Mott insulator phase, in particular the one particle-hole excitation band. Within the framework of perturbation theory we obtain an analytical expression for the dynamic structure factor $S(q,ω)$ and use it to calculate the imparted energy which has shown to be a relevant observable in recent experiments. We test the accuracy of our approximations by comparing them with numerically exact solutions of the Bose-Hubbard model in restricted cases and establish the limits of validity of our linear response analysis. Finally we show that when the system is deep in the Mott insulator regime, its response to the Bragg perturbation is temperature dependent. We suggest that this dependence might be used as a tool to probe temperatures of order of the Mott gap.

description: The rational choice methodology is gaining in popularity not just because it tends to generate lots of observable predictions, but also because it tends to generate novel predictions. Theorists of rational choice use mathematics models to еxplain sense of complicated interactions between individuals. Model of the rational choice in the domain of crime has adopted two standards of economic rationality: the selfinterested standard of rationality and the present-aim standard. The self-interested standard of rationality assumes that people are basically motivated to pursue their own economic interests. In contrast, the present-aim standard allows diverse interests: cultural, social, psychological or emotional. This paper discusses the influence of certain factors on the process of making decisions within the domain of crime. Special attention is paid to (some) sociological, psychological and other non-economic factors whic have an influence on the decision of an individual to violate the law in order to gain an enormous amount of money.

In doing so, the awareness of market approaches – the constant and intensive market changes - is the first and basic supposition on which it would be wise to base new strategies that are different from the competitors’ in innovation, technology and quality. New strategies, conditionally, must also include the provision of critical money supply as well as stimulating economic policy, which enable us to keep up with the up-to-date market, technological and marketing trends.

description: We use bulge-type classifications of 809 representative SDSS galaxies by Gadotti (2009) to classify a large sample of galaxies into real bulges (classical or elliptical) and pseudobulges using Random Forest. We use structural and stellar population predictors that can easily be measured without image decomposition. Multiple parameters such as the central mass density with 1 kpc, concentration index, Sérsic index and velocity dispersion do result in accurate bulge classifications when combined together. We classify $\sim 44,500$ face-on galaxies above stellar mass of 10$^{10}$ M$_\odot$ and redshift $ 0.02 < z < 0.07$ into real bulges or pseudobulges with $93 \pm 2$\% accuracy. We show that $\sim 75 - 90\%$ of AGNs identified by the optical line ratio diagnostic are hosted by real bulges. The pseudobulge fraction significantly decreases with AGN signature as the line ratios change from indicating pure star formation ($\sim 54 \pm 4$ \%), to composite of star formation and AGN ($\sim 18 \pm 3$\%), and to AGN-dominated galaxies ($\sim 5 \pm 3$\%). Using the dust-corrected [\ion{O}{3}] luminosity as an AGN accretion indicator, and the stellar mass and radius as proxies for a black hole mass, we find that AGNs in real bulges have lower Eddington ratios than AGNs in pseudobulges. Real bulges have a wide range of AGN and star formation activities, although most of them are weak AGNs. For both bulge-types, their Eddington ratios are correlated with specific star formation rates (SSFR). Real bulges have lower specific accretion rate but higher AGN fraction than pseudobulges do at similar SSFRs.

An adaptive method for DC current reduction in totem pole power factor correction converters

Publisher: name: IEEE
Year: 2022

description: Enabled by improved wideband gap semiconductor devices, the bridgeless totem pole power factor correction (PFC) converter is becoming an increasingly popular topology for front end ac input of high power battery chargers and telecom power supplies, achieving high efficiency as well as low electromagnetic interference. Unlike the conventional boost PFC, in a totem pole structure, different circuits are used for shaping the current in positive and negative half cycles. As a result, sensing inconsistencies may result in a significant dc component in the input current. In field applications, accumulation of dc currents from multiple PFC rectifier based loads can potentially lead to saturation of distribution transformers. This article proposes a low-cost method for adaptive detection and reduction of the dc input current based on time domain analysis of the dc link voltage. The effectiveness of the method in compensating manufacturing tolerances is experimentally validated on a 390 V, 1450 W interleaved totem pole PFC converter, and dc current reduction of up to 99.6% is achieved.

How Are Women Making the Decision to Have an Elective Cesarean Section When There is No Medical Indication? : A Scoping Review
Creators: name: Randhawa, Prabhjot
Publisher: name: The University of British Columbia
Year: 2021

description: Background: Globally, elective cesarean sections without medical indication have recently seen a rise and British Columbia holds one of the highest rates of cesarean delivery in Canada. The decision-making process behind a woman’s choice to have an elective surgical delivery when there is no medical indication is important to gain knowledge about, as this procedure is not without maternal and neonatal risks, is costly, and adds further strain to nursing workload. Methods: A scoping review was conducted and 12 published articles were examined using the 2005 Arksey and O’Malley methodological framework and the Matrix Method Garrard (2011). Findings: Various approaches were noted globally, in terms of who was the provider of counseling (the primary care provider, team members, or pregnant women themselves) and how counseling was provided (during regular prenatal appointments, dedicated counseling sessions, or independent research by the woman). Themes were identified amongst the type of information women receive during counseling, including discussion of the risks and benefits of both cesarean and vaginal delivery, the woman’s fears/concerns, and future reproductive family planning. Conclusion: The comprehensive review of the literature suggested that a team-based and multisessional counseling approach when discussing mode of delivery may decrease the number of women opting for a cesarean section without medical indication. This is a type of counseling that Canadian nurses may be able to provide for pregnant women as they are respected members of the health care team and it is within their scope to educate and support women during the perinatal period. Finally, knowledge gaps were identified which require further research, including gaining knowledge on Canadian approaches to decision-making for women regarding mode of delivery and determining adequacy of counseling

description: This research aimed to mitigate fouling in membrane bioreactors (MBR) through concurrent usage of zinc oxide as an antibacterial agent (A) and sodium alginate as a hydrophilic agent (H) within a polyacrylonitrile membrane (PM) structure. The antibacterial polymeric membranes (APM) and antibacterial hydrophilic polymeric membranes (AHPM) synthesized showed a higher porosity, mechanical strength and bacterial inhibition zone, and a lower contact angle in comparison with PM membranes. EDS, SEM and AFM analyses were used to characterize the chemical, structural, and morphological properties of PM, APM, and AHPM. The flux of PM, APM, and AHPM in MBR was 37, 48, and 51 l m−2 h−1 and COD removal was 81, 93.5, and 96.7%, respectively. After MBR operation for 35 days in an urban wastewater treatment, only 50% of the flux of PM was recovered, while the antibacterial and hydrophilic agents yielded a flux recovery of 72.7 and 100% for APM and AHPM, respectively.

Integration of current techologies that we can no longer say that they are new , has become imperativ for all participants who wish to compete in the global market. In these activities, special emphasis should be put on attraction of new customers and maintaining good relation with the existing ones. Therefore, ranges of available information technologies should be maximized in creating an efficient communication with customers, but also with all other participants in the market. In a competitive market, what is today, one of the potential market opportunities is precisely the use of modern information technology to improve overall operations, especially communications relationships with customers, which will be discussed in this paper

description: The objectives of the work were to check the possibility of obtaining data from the FADN system for the EDF survey and to compare the economic results achieved by dairy farms from the selected EU countries in 2016. The additional objective was to determine the profitability threshold for milk production at the level of general and full costs. The average data was used for the analysis within EDF and the Polish group and their tercyl separated due to the total cost of milk production. The average national results within EDF in 2016 were also analyzed. Measures for the evaluation of the results was the level of agricultural income, and income from management and risks in the dairy industry. Two break even points of producing 100 kg of milk expressed by total and full costs were also assessed. The lowest total cost of production was incurred by the farm with large scale production, expressed as the number of cows in the herd and milk yield per cow. In addition, these farms were characterised by greater participation of grassland than arable land in forage area, of which more than half was rented. Polish and Irish farms were characterised by the lowest total costs in milk production out of the analyzed countries. Based on the results relying on opportunity costs of own factors in milk production, it should be noted that the Polish farm obtained the lowest entrepreneur income. Apart from Irish farms, milk production in the analyzed countries in 2016 was unprofitable.

description: This paper proposes the optimal policies for a fuzzy inventory model considering the holding cost and ordering cost as continuous functions of time. Shortages are allowed and partially backlogged. The demand rate is assumed in such to be linearly dependent on time during on-hand inventory, while during the shortage period, it remains constant. The inventory problem is formulated in crisp environment. Considering the demand rate, holding cost and ordering cost as trapezoidal fuzzy numbers, the proposed problem is transformed into fuzzy model. For this fuzzy model, the signed distance method of defuzzification is applied to determine the average total cost (ATC) in fuzzy environment. The objective is to optimize the ATC and the order quantity. One solved example is provided in order to show the applicability of the proposed model. The convexity of the cost function is verified with the help of 3D-graph.

description: The beta-decay of $\rm^{85}Kr$ is a significant radioactive background for experiments that use liquified noble gases to search for dark matter and measure the low-energy solar neutrino flux. While there are several proposed methods for reducing Kr levels in these experiments, an independent technique is needed for measuring very low Kr levels. By selectively exciting Kr atoms to a metastable state, capturing them in a magneto-optical trap (MOT), and detecting fluorescence from the trapped atoms, individual Kr atoms can be counted with a high signal-to-noise ratio. This approach could be used to ascertain Kr impurity levels in other noble gases, with an estimated sensitivity of $3\times 10^{-14}$.

description: Restless legs syndrome (RLS) is a sleep-related disorder characterized by abnormal sensations in the legs at restin which the patients feel an urge to move the legs; beginning or worsening during inactivity; relief by movement;preponderance in evening or night. The drugs implicated were mainly psychotropic, especially neuroleptics and manyothers. Drug induced RLS generally resolves when the dose is reduced or the drug is withdrawn.We report a case of bipolar mood disorder presented to our emergency department with insomnia and we addedquetiapine 100mg at bed time for his disturbed sleep, patient reported on third day complaining with “itchy”, “Pins andneedles”, “creepy crawly” feeling in the legs. The sensations are usually worse at rest and night due to which he is unableto sleep. Awareness and proper diagnosis by all primary care practitioners is necessary for effective management of RLSas well as clinicians are encourage to be aware of the potential for quetiapine to cause RLS

description: For quantitative seismic imaging, iterative least-squares reverse time migration is the recommended approach. The existence of an inverse of the forward modelling operator would considerably reduce the number of required iterations. In the context of the extended model, such a pseudo-inverse exists, built as a weighted version of the adjoint and accounts for the deconvolution, geometrical spreading and uneven illumination. The application of the pseudo-inverse Born modelling is based on constant density acoustic media, which is a limiting factor for practical applications. To consider density perturbation, we propose and investigate two approaches. The first one is a generalization of a recent study proposing to recover acoustic perturbations from angle-dependent response of the pseudo-inverse Born modelling operator. The new version is based on weighted least-squares objective function. The method not only provides more robust results, but also offers the flexibility to include constrains in the objective function in order to reduce the parameters cross-talk. We also propose an alternative approach based on Taylor expansion that does not require any Radon transform. Numerical examples based on simple and the Marmousi2 models using correct and incorrect background models for the variable density Born modelling, verify the effectiveness of the weighted least-squares method when compared with the other two approaches. The Taylor expansion approach appears to contain too many artifacts for a successful applicability.

description: We use the classical version of the density-functional theory in the weighted-density approximation to build up the entire phase diagram and the interface structure of a two-dimensional lattice-gas model which is known, from previous studies, to possess three stable phases -- solid, liquid, and vapour. Following the common practice, the attractive part of the potential is treated in a mean-field-like fashion, although with different prescriptions for the solid and the fluid phases. It turns out that the present theory, compared to similar theories in the continuum, is of worse quality. Nevertheless, at least a number of qualitative facts are reproduced correctly: i) the existence of three phases; ii) the disappearance of the liquid phase when the range of the attraction is progressively reduced; and iii) the intrusion, just below the triple-point temperature, of a liquid-like layer at the interface between the coexisting solid and vapour phases.

description: Hydrogel coatings effectively reduce the attachment of proteins and organisms in laboratory assays, in particular when made from zwitterionic monomers. In field experiments with multiple species and non-living material, such coatings suffer from adsorption of particulate matter. In this study, the zwitterionic monomer 3-[N-(2-methacryloyloxyethyl)-N,N-dimethylammonio] propanesulfonate (SPE) was copolymerized with increasing amounts of the photo-crosslinker benzophenon-4-yloxyethyl methacrylate (BPEMA) to systematically alter the density of crosslinks between the polymer chains. The effect of increasing crosslink density on the antifouling (AF) performance of the coatings was investigated in laboratory assays and fields tests. In both cases, the AF performance was improved by increasing the crosslinker content. The coatings reduced protein, diatom, and barnacle accumulation, and showed better resistance to biomass accumulation. The findings underline that the marine AF performance of hydrogel coatings does not only depend on the specific chemical structure of the polymers, but also on their physico-chemical properties such as rigidity and swelling.

description: The purpose of the paper is to compare population of farmers that bought crop insurance with farmers that are uninsured. Based thereon, the author identified features characterizing the insured farmers. These findings were applied to draw more general conclusions concerning factors influencing the insurance awareness and propensity to buy insurance coverage. Demographic, social and economic criteria, individual perception of risk, the loss ratio, and the willingness to pay the insurance premium were taken into consideration. Empirical research is based upon a sample of 150 Polish farmers that were interviewed using the CATI approach. It was found that farms with greater production volume (annual income) and with a larger crop area present higher willingness to buy insurance. Farmers who experienced damage to crops are more inclined to buy insurance coverage. Moreover, higher insurance penetration rate can be found among farmers who are willing to pay a higher price for a crop insurance policy. Surprisingly, despite frequently formulated assumptions, variables such as age of farmer, level of education or individual perception of risk do not determine the decision on insurance purchase.
