Distributions of relaxation times in relaxor ferroelectric Ba(Ti0.8 Ce0.2)O3

Abstract The dielectric behavior of the Ba(Ti0.8Ce0.2)O3 ceramics was studied by broadband dielectric spectroscopy in a temperature interval 140–500 K. The broad dielectric relaxation was analyzed by the Havriliak–Negami relationship and the distribution of relaxation times formalism. It was found that the Havriliak–Negami average relaxation time, longest and most probable relaxation times from the distribution of relaxation times follow the Vogel–Fulcher law. The freezing temperature of the longest relaxation time is substantially higher than the freezing temperature of the most probable relaxation time, indicating the distribution of freezing temperatures. The dielectric dispersion has all features inherent to relaxor ferroelectrics and the relaxation is assigned to the dynamics of polar nanoregions.
Production of Functional Kampong Chicken Meat with Low Cholesterol, High Antioxidant, and Unsaturated Fatty Acids Fed Noni (Morinda citrifolia) Leaf Shoot Meal

The objective of this study was to evaluate the effect of noni (Morinda citrifolia) leaf shoot meal (NLSM) supplementation in the ration on the performances of kampong chickens as well as lipid, malondialdehyde (MDA), and fatty acid contents of meats. Two hundred and forty kampong chickens of 4 weeks old were reared until 12 weeks old. The diet treatments were R0: 0% NLSM (control), R1: 0.5% NLSM, R2: 1% NLSM, R3: 1.5% NLSM, R4: 2% NLSM, and R5: 2.5% NLSM. A completely randomized design (CRD) was used with six treatments and four replications with ten kampong chickens per replicate. The data were analyzed using ANOVA and if there were significant different, the data were further analyzed using Duncan’s Multiple Range Test. The variables measured were performances of kampong chickens as well as lipid, MDA, and fatty acid contents of meat. The result showed that cholesterol and LDL contents of meat were significantly reduced by feeding NLSM. Performance and HDL contents of meat were not significantly different for all diet treatments. In addition, feeding kampong chickens with ration supplemented with NLSM could reduce MDA, saturated fatty acids and increase unsaturated fatty acids contents of meat. It is concluded that 2.5% NLSM can be used to improve meat quality of kampong chicken as functional meat.
Consumer Drivers of Industry Growth and Household Loyalty to Private Security Firms in Jamaica

Jamaica is the fourth most murderous country in the world with more than 100 murders per 100,000 population. Private security firms have grown to record levels and have outnumbered the police and military combined, thus making private security an extremely important part of the security landscape in the country. This article seeks to explain household loyalty to private security providers and the rapid growth of private policing and protection in the country. Prior research has rarely addressed this issue, particularly in a developing world context. Utilizing a final sample of 108 private security customers in Jamaica and partial least squares structural equation modeling (PLS-SEM) for data analysis, the study finds that good relationships between customers and security providers and the service quality offered by private security firms are key drivers of household loyalty. In addition, lack of confidence in the police, service quality offered, and the high levels of “indiscipline” in the Jamaican society are causal to the increased growth in the private security industry.
The nexus between Indonesia’s exchange rate and the world crude palm oil price

Objective: International trade plays a major role in increasing the output of each country. Crude Palm Oil (CPO) is one of Indonesia’s major export commodities. Facts show over the past two decades, CPO has become a fast-growing product. However, there are obstacles from one of Indonesia’s CPO importers, namely the European Union. The aim of this study is to explore the nexus between the exchange rate and the world price of CPOs. Research Design & Methods: This study uses both the exchange rate of Indonesia and the price data of the world CPO from 1981-2017 as secondary. Granger Causality was used to explain the nexus between the exchange rate and the world price of CPOs. Findings: The results of the Granger Causality showed there was no causality between the exchange rate and the price of the world CPO. The lack of causality between the two variables suggests the trade balance’s position is stronger and able to explain the exchange rate. Contribution & Value Added: This study indicated that the IDR exchange rate is more sensitive to trade balance rather than the world CPO price. Moreover, It is necessary to refined palm oil products to increase the contribution of the non-oil sector in Indonesia. In addition, the Indonesian government needs to be aware of the European Union’s raised barriers to world trade. It means that Indonesia can make a positive campaign about the ad-vantages of palm oil production.
Tomographic Imaging of Traveling Ionospheric Disturbances Using GNSS and Geostationary Satellite Observations

Traveling ionospheric disturbances (TIDs) are the manifestations of atmospheric gravity waves in the ionosphere. These disturbances have practical importance because they affect satellite navigation technologies such as Global Navigational Satellite System (GNSS), causing degradation in precise positioning applications. They also have scientific significance as their generation mechanisms and propagation are not fully understood. While there are specific instruments that can measure TIDs in certain locations, there is a need for wide‐area observations across extended geographical regions to continuously monitor their onset and spatial and temporal characteristics. This paper evaluates the use of observations from ground‐based geodetic GNSS receivers to image TIDs using ionospheric tomography and data assimilation. Certain GNSS receivers also monitor signals from geostationary (GEO) satellites, which provide a unique perspective on the TID. The advantage of using the GEO data is investigated. A computerized simulation of GNSS observations is used for evaluation of the Multi‐Instrument Data Analysis System (MIDAS) with GEO and regular GNSS geometry. The simulated observations are generated by integrating the electron density through a modeled TID‐perturbed dynamic ionosphere between actual receiver and satellite positions. The output 3‐D electron density image series generated from the synthetic data by the MIDAS ionospheric tomography and data assimilation algorithm are compared with the input model ionosphere. Results show that GEO geometry improves the reconstruction of medium‐scale TIDs (MSTIDs) and smaller LSTIDs in cases where the movement of regular GNSS satellites in Medium Earth orbit (MEO) may otherwise introduce distortions to the observations.
Chronic viral infection promotes early germinal center exit of B cells and impaired antibody development

Chronic viral infections disrupt B cell responses leading to impaired affinity maturation and delayed control of viremia. Previous studies have identified early pre-germinal center (GC) B cell attrition but the impact of chronic infections on B cell fate decisions in the GC remains poorly understood. To address this question, we used single-cell transcriptional profiling of virus-specific GC B cells to test the hypothesis that chronic viral infection disrupted GC B cell fate decisions leading to suboptimal humoral immunity. These studies revealed a critical GC differentiation checkpoint that is disrupted by chronic infection, specifically at the point of dark zone re-entry. During chronic viral infection, virus-specific GC B cells were shunted towards terminal plasma cell (PC) or memory B cell (MBC) fates at the expense of continued participation in the GC. Early GC exit was associated with decreased B cell mutational burden and antibody quality. Persisting antigen and inflammation independently drove facets of dysregulation, with a key role for inflammation in directing premature terminal GC B cell differentiation and GC exit. Thus, these studies define GC defects during chronic viral infection and identify a critical GC checkpoint that is short-circuited, preventing optimal maturation of humoral immunity.
Does a Damaged‐Fault Zone Mitigate the Near‐Field Impact of Supershear Earthquakes?—Application to the 2018 
 Mw 7.5 Palu, Indonesia, Earthquake

The impact of earthquakes can be severely aggravated by cascading secondary hazards. The 2018 Mw 7.5 Palu, Indonesia, earthquake led to devastating tsunamis and landslides, while triggered submarine landslides possibly contributed substantially to generate the tsunami. The rupture was supershear over most of its length, but its speed was unexpectedly slow for a supershear event, between the S wave velocity VS and Eshelby's speed 2VS , an unstable speed range in conventional theory. Here, we investigate whether dynamic rupture models including a low‐velocity fault zone can reproduce such a steady supershear rupture with a relatively low speed. We then examine numerically how this peculiar feature of the Palu earthquake could have affected the near‐field ground motion and thus the secondary hazards. Our findings suggest that the presence of a low‐velocity fault zone can explain the unexpected rupture speed and may have mitigated the near‐field ground motion and the induced landslides in Palu.

Shifting from Old Open Government to New Open Government: Four Critical Dimensions and Case Illustrations

Abstract Entering the 2000s, the open government movement along with open data policy gradually has taken over NPM, a long-standing global government reform for more than two decades. Despite the distinctive characteristics of recent open government initiative, it is arguably considered to be an extension of the conventional open government movement for right-to-know represented by the Freedom of Information Act of 1966 in the U.S. However, we argue new open government is different from old open government in terms of four dimensions: policy focus, nature of information, primary value, and role of citizens. New open government initiatives have shifted their policy focus from simple right-to-know to open data; the nature of information from traditional paper-based forms of information to machine-readable and reusable data; primary values from transparency to citizen participation and networked collaborative governance; and role of citizens from passive informed and service recipients to active co-producers of public services and users of open data. These points are specifically illustrated in this paper with selected open government initiatives undertaken by the Korean government.
The inflammatory microenvironment in vestibular schwannoma

Abstract Vestibular schwannomas are tumors arising from the vestibulocochlear nerve at the cerebellopontine angle. Their proximity to eloquent brainstem structures means that the pathology itself and the treatment thereof can be associated with significant morbidity. The vast majority of these tumors are sporadic, with the remainder arising as a result of the genetic syndrome Neurofibromatosis Type 2 or, more rarely, LZTR1-related schwannomatosis. The natural history of these tumors is extremely variable, with some tumors not displaying any evidence of growth, others demonstrating early, persistent growth and a small number growing following an extended period of indolence. Emerging evidence now suggests that far from representing Schwann cell proliferation only, the tumor microenvironment is complex, with inflammation proposed to play a key role in their growth. In this review, we provide an overview of this new evidence, including the role played by immune cell infiltration, the underlying molecular pathways involved, and biomarkers for detecting this inflammation in vivo. Given the limitations of current treatments, there is a pressing need for novel therapies to aid in the management of this condition, and we conclude by proposing areas for future research that could lead to the development of therapies targeted toward inflammation in vestibular schwannoma.
Select, then decide: Further evidence for separable selection and decision processes in short-term visual recognition

ABSTRACT Recently, researchers have used evidence-accumulation models to analyse how performance in visual working memory (WM) tasks depends on both decision-making and non-decisional processes. One resulting claim is that selection of representations into the focus of attention and decision-making about those representations are separable processes, that this selection is facilitated by informative retro-cues, and that this process is evident in non-decision time when data are fit with a diffusion model. I attempted to address an alternative account of retro-cue effects on non-decision time: that they result from reduced uncertainty about non-memorial aspects of the task. In two 2AFC recognition experiments with retro-cues, participants had to choose between two probes – whose similarity to one another varied across conditions – to indicate which matched an item presented at a specified location in a sequentially-presented visual memory array. Crucially, the task minimized differences in uncertainty between the cue and no-cue conditions. Modelling showed a robust retro-cue effect in non-decision time, consistent with the advanced selection account of the retro-cue effect. Additionally, there were serial position and similarity effects, mostly evident on drift rate. These results support the contention that selection into the focus of attention is a separate process which facilitates stimulus use in decision-making.
Spectrum of microbial infection in an Intensive Care Unit: a single centre tertiary care experience in Southern Indian state of Karnataka

Background: There is an increased incidence of hospital acquired infection, especially in ICU setting, the most common being ICU acquired pneumonia which increases the morbidity, mortality, prolongs hospital stay and consuming more resources. Microbial etiology of intensive care unit (ICU)-acquired pneumonia (ICUAP) determines antibiotic treatment and outcomes which vary from centre to centre. Hence, a study of risk factors, clinical profile of patient, microorganisms and their resistance patterns to antibiotics are important for the diagnosis, prognosis of patient with ICU acquired pneumonia and also in the prevention of the same. Methods: Patients with ICUAP confirmed microbiologically were prospectively compared according to identification of 1 (monomicrobial) or more (polymicrobial) potentially pathogenic microorganism. Patients without microbiological confirmation were excluded from the study. We assessed clinical characteristics, microbiology and outcome variables. Results: In the present study 60 patients with ICU Pneumonia were included out of which 50 (83%) had mono-microbial infection. Most common organism isolated in mono microbial infection was Klebsiella species (26%), followed by Acinetobacter species (25%), out of which 20 percent was multidrug resistant. Multi-drug resistance was similarly frequent in both groups. Outcome variables like initial response to the empiric treatment, length of stay and mortality were similar in both monomicrobial and polymicrobial pneumonia. Mortality rates were higher with higher pneumonia scores (p value <0.002) and with multi organ dysfunction (p <0.008) irrespective of mono microbial or poly microbial infection. Conclusions: In this study mono microbial infection was more than polymicrobial, the most common organism being Kliebsiella species followed by Acinetobacter species. When empiric treatment is frequently appropriate, mortality rates were higher with higher pneumonia scores and MODS. In our study polymicrobial aetiology did not influence the outcome of ICUAP.
Multifocal calcifying fibrous tumor mimicking malignancy

Calcifying fibrous tumor synonymous with calcifying fibrous pseudotumor is a rare benign mesenchymal tumor, recently been described in soft tissues. It is believed to be a true neoplasm with a tendency for nondestructive local recurrence. It presents as a single or multifocal well circumscribed but unencapsulated mass with variable size and may infiltrate into surrounding tissue. It is characterized histologically by hyalinized collagenous fibrous tissue, with bland spindle cells, psammomatous or dystrophic calcifications, and focal lymphoplasmacytic infiltrate. We present a rare case of multifocal calcifying fibrous tumors in retroperitoneum and in right adnexa in a 32-year-old female patient who presenting with pain in left lower abdomen. Imaging revealed large calcified solid mass lesion in right posterior para-renal space infiltrating into segment VI of liver and a similar smaller calcified mass in right adnexa which was confused with malignancy.

On mechanisms of light-induced deformations in photoreceptors

Photoreceptors in the retina convert light into electrical signals through a phototransduction cycle that consists of multiple electrical and biochemical events. Phase-resolved optical coherence tomography (pOCT) measurements of the optical path length (OPL) change in the cone photoreceptor outer segments after a light stimulus (optoretinogram) reveal a fast, ms-scale contraction by tens of nm, followed by a slow (hundreds of ms) elongation reaching hundreds of nm. Ultrafast measurements with a line-scan pOCT system show that the contractile response amplitude increases logarithmically with the number of incident photons, and its peak shifts earlier at higher stimulus intensities. We present a model that accounts for these features of the contractile response. Conformational changes in opsins after photoisomerization result in the fractional shift of charge across the disk membrane, leading to a transmembrane voltage change, known as the early receptor potential (ERP). Lateral repulsion of the ions on both sides of the membrane affects its surface tension and leads to its lateral expansion. Since the volume of the disks does not change much on a ms time scale, their lateral expansion leads to an axial contraction of the outer segment. With increasing stimulus intensity and resulting tension, the area expansion coefficient of the disk membrane also increases as thermally-induced fluctuations are pulled flat, resisting further expansion. This results in a logarithmic saturation of the deformation and a peak shift to earlier with brighter stimuli. Slow expansion of the photoreceptors is explained by the influx of water due to osmotic changes during phototransduction. Both effects closely match measurements in healthy human volunteers.
Influence of Career Management on Performance of Firms Listed in the Nairobi Securities Exchange in Kenya

The study sought to determine the influence of career management on firm performance at the firms which are listed in the Nairobi Securities Exchange. The study was anchored on resource based view theory and shareholder value maximization theory. The research design used was a cross-sectional survey, target population included the head of human resources and finance directors in all the listed firms since they were better placed and conversant with the subject of this study and were involved in the development of the policies and review of performance. Sample size comprised of 136 respondents and data was collected through structured questionnaires to meet the objectives of the study. Responses were tabulated, coded and processed by use of a computer Statistical Package for Social Science (SPSS) to analyze the data. Both descriptive and inferential statistics techniques were used to analyze the data. Findings revealed that the relationship between career management and firm performance was positive and statistically significant. The study concluded that career development and planning, career mentors/ counseling, career centres and firms planning for employee growth and progression are key career management determinants for the performance of firms listed in the Nairobi Stock Exchange (NSE) and recommended that career management practices should be widely adopted by NSE listed firms as doing so would lead to improved performance

The simultaneous presence of these three malformations is extremely rare; the incidence is estimated to be 1.5 per 100.000. 000 births. Conclusion: Oral hygiene management of patients with EEC syndrome is important and dental practitioners need to know the oral and dental conditions presenting with this syndrome.
Self-Supervised GAN Compression

Deep learning's success has led to larger and larger models to handle more and more complex tasks; trained models can contain millions of parameters. These large models are compute- and memory-intensive, which makes it a challenge to deploy them with minimized latency, throughput, and storage requirements. Some model compression methods have been successfully applied to image classification and detection or language models, but there has been very little work compressing generative adversarial networks (GANs) performing complex tasks. In this paper, we show that a standard model compression technique, weight pruning, cannot be applied to GANs using existing methods. We then develop a self-supervised compression technique which uses the trained discriminator to supervise the training of a compressed generator. We show that this framework has a compelling performance to high degrees of sparsity, can be easily applied to new tasks and models, and enables meaningful comparisons between different pruning granularities.
