The BMRC/NCAR C-Band Polarimetric (C-POL) Radar System

Abstract The development of the first Australian C-band polarimetric/Doppler meteorological radar system (C-POL) is described. Motivated by the need to obtain improved rainfall estimation and the vertical profile of hydrometeors, C-POL was developed jointly by the Bureau of Meteorology (BOM), the Commonwealth Scientific and Industrial Research Organisation of Australia, and the National Center for Atmospheric Research. C-POL is based on a standard operational C-band radar employed by the BOM but modified to be capable of transmitting linear horizontal and vertical polarizations and receiving the co- and cross polarizations on a pulse-to-pulse basis. Standard variables extracted include horizontal reflectivity (ZHH), radial velocity (Vr), spectral width (συ), differential reflectivity (ZDR), differential phase shift (ΦDP), and zero lag correlation coefficient [ρHV(0)]. With the addition of a second receiver chain, the linear depolarization ratio will soon be available. Initial results with the radar are di.
Characterization and Stability of ‘de Russas’ Orange Juice From Organic Cultivation

The objective of this study was to elaborate whole juice from the varieties of BRS ‘Russas 01’ and BRS ‘Russas 02’ from the orange tree ‘de Russas’, with organic certification and to analyse its quality characteristics. Twenty fruits of each variety were used to prepare the juice, with physicochemical analysis of pH, soluble solids, titratable acidity and the soluble solids/titratable acidity ratio (Ratio). The content of citric acid and vitamin C by high performance liquid chromatography using a UV detector. The stability of vitamin C during three days of storage at 4 °C. The volatile organic compounds by gas chromatography coupled with mass spectrometry. Data were evaluated by analysis of variance and Student’s t-test at 5% significance level. The pH presented an average higher than 4.00, an average content of soluble solids above 10 °Brix and Ratio 7, in compliance with the legislation. The vitamin C was maintained at the end of storage at 79.33% for variety ‘01’ and 86.40% for variety ‘02’. Thirty compounds were identified in the volatile fraction for variety ‘01’ and 61 compounds for variety ‘02’. Thus, it is possible to conclude that the variety BRS ‘Russas 02’ has greater potential to produce whole juice.
Synchronization criteria in complex dynamical networks with nonsymmetric coupling and multiple time-varying delays

In this article, we consider a generalized complex dynamical network model with nonsymmetric coupling, and the dynamics of each node has a different time-varying delay. Criteria of exponential synchronization are derived in terms of linear matrix inequalities for the model by constructing suitable Lyapunov functionals. The obtained outcomes are different from those in the current literature, in which the complex dynamical networks are coupling symmetrically and delays are fixed constants. Moreover, the given sufficient conditions extend current available results and are verifiable. A numerical example is provided to illustrate the efficiency of the derived outcome.
Politics of Emancipation: A Feminist Defense of Randomly Selected Political Representatives

ABSTRACT The presence of women in elected assemblies has been argued to transform the political agenda so that it better addresses the needs and interests of women. In this article, I reflect on women’s political representation by starting from democratic theories that point to the inadequacy of electoral democracy. I argue that, compared to including women in the political elite, dissolving the division of political labor between professional politicians and ‘ordinary’ citizens has a greater potential to challenge status quo gender relations. I suggest that political assemblies consisting of randomly selected citizens would better serve women’s self-determination and emancipation for three reasons: 1) allotted representatives would be more willing and able than elected representatives to critique social norms and practices, 2) the idea of allotted representatives better supports the idea that knowledge is situated, and 3) it better accommodates the notion that political merit is a gendered, racialized and class-based concept.
Nonsteady state ionosphere-plasmasphere coupling of superthermal electrons

Numerical solutions to the nonsteady state kinetic equation which describes the transport of superthermal electrons in the ionosphere and plasmasphere between the magnetically conjugate regions of the ionosphere are presented. The distribution function in time, distance along arbitrary geomagnetic field lines, energy, and pitch angle are among the parameters calculated by the model. This model represents a unified approach by self-consistently coupling the interaction of the two hemispheres and the trapping of superthermal electrons in the plasmasphere. Our calculations take into account the various ionization and excitation processes and the effect of an inhomogeneous magnetic field (i.e., magnetic mirroring of precipitating electrons and focusing of escaping electrons along magnetic field lines). Omnidirectional flux spectra and pitch angle distributions are shown for various L shells and situations, and the features are described in detail. Nonsteady state calculations predict that a depleted flux tube can take several hours to reach steady state levels again. Plasmaspheric transparencies are calculated for different conditions of illumination, scattering processes in the conjugate ionospheres, and field-aligned gradients of the thermal plasma density. Plasmaspheric transparency is found to be a complicated function of not only the plasmaspheric thermal plasma but also the ionospheric sources and scattering processes. A phenomenological model is used to describe the energy transmission, reflection, and deposition in the plasmasphere. By studying the ionosphere and plasmasphere as one system rather than two separate ones, substantial corrections are introduced in the values of key parameters describing photoelectron fluxes.
French cross-cultural adaptation and validation of the International Trauma Questionnaire (ITQ) in a French community sample

ABSTRACT Aims: In 2018, the 11th version of the International Classification of Diseases (ICD-11) recognized a new diagnosis in addition to Posttraumatic Stress Disorder (PTSD), that of Complex Posttraumatic Stress Disorder (C-PTSD). A new measurement tool was developed to assess both disorders: the International Trauma Questionnaire. The objectives of this study were (a) to conduct a French translation of the tool, (b) to confirm the factorial structure of the tool, (c) to verify its convergent and divergent validity, (d) and finally to ensure its temporal stability. Method: The ITQ was translated into French using a committee approach, bringing together experts and bilingual individuals with a dual French-English culture. It was then completed by 750 people residing in France and having been exposed to potentially traumatic events, recruited from the general population. Other measures were also completed (HADS, ITEM, PCL-5, WHO-5, DERS). Results: Confirmatory factor analysis confirmed that the French version of the ITQ had the same factor structure as the original version. The scale showed satisfactory convergent and divergent validity, as well as good stability over time. Conclusion: Our study suggests that the French version of the ITQ is a good measurement tool for assessing PTSD and C-PTSD according to the ICD-11 diagnostic criteria. HIGHLIGHTS This study provides the first translation and validation of the International Trauma Questionnaire in the French population. Confirmatory factor analysis confirmed that the French version of the ITQ had the same factor structure as the original version. The French version of the ITQ showed good convergent and divergent validity, as well as good test-retest reliability.
A New Look at Homogeneous Ice Nucleation in Supercooled Water Drops

Abstract The classical theory for homogeneous ice nucleation in supercooled water is investigated in the light of recent data published in various physico-chemical journal on the physical properties of supercooled water and in the light of recent evidence that the cooperative nature of the hydrogen bonds between water molecules is responsible for a singularity behavior of pure supercooled water at −45°C. Recent rates for homogeneous ice nucleation in supercooled water drops field from field experiments at the cirrus cloud level and from cloud chamber studies were shown to be quantitatively in agreement with the laboratory-derived lowest temperatures to which ultrapure water drops of a given size have been supercooled. Using these verified nucleation rates together with the recent physical property data for supercooled water, the activation energy for the transfer of water molecules across the ice-water interface was computed using the classical nucleation rate equation. The thus computed values are signif.
Subjective Well-Being and Active Life Expectancy in Japan: Evidence From a Longitudinal Study

Abstract Background and Objectives Existing research has suggested that older adults in Japan enjoy phenomenal physical health status, but they have poor subjective well-being (SWB). Limited empirical evidence exists, however, on how physical health and SWB intersect and are linked to the lives of older men and women in Japan. Using the concept of health expectancy, this study examines the role of SWB, as measured by life satisfaction, in the mortality and morbidity experiences of Japanese adults aged 65 years and older. Research Design and Methods We used the nationally representative Nihon University Japanese Longitudinal Study of Aging, 1999–2009. Our measurement of morbidity is disability, based on difficulty in activities in daily living (ADLs) and instrumental ADLs. We use the Interpolation of Markov Chains approach to compute life expectancy (LE), LE without disability (active LE), and LE with differing severity of disability for those who are satisfied with life and for those who are not. Results We documented significant differences in LE and active LE by the state of life satisfaction among older adults in Japan. Men and women who are satisfied with life are expected to live longer and spend more years without having disability compared to those who are not satisfied. We found no differences in the length of life with disability of differing severity by the state of life satisfaction. Discussion and Implications Our results highlight the important role of SWB at older ages in Japan, because it is directly related to the physical health of its aging population. Fully understanding the health of the older population requires research that focuses on both objective and subjective dimensions of well-being.
Analytical determination of bifurcations in an impact oscillator

It is well known that some solutions for a sinusoidally driven oscillator with linear stiffness and impacts at rigid stops modelled with a coefficient of restitution impact law can be located analytically. Recently, new co-dimension one bifurcations called grazing bifurcations have been found in such systems. Here we present analytical results which show how the type of grazing bifurcation changes with parameter, and that when the type of grazing bifurcation changes a codimension two bifurcation occurs. The simplest grazing bifurcations involve orbits of period-1, but we show that the same analytical methods can be used to locate some subharmonics and their bifurcations.
Polymer coating for higher pesticide use efficiency, seed yield and quality in onion (Allium cepa)

Onion (Allium cepa) seed crop is infected with several pest and diseases which reduce the seed yield and quality. The present study explores the feasibility of using polymer as an efficient delivery system for seed-protectant chemicals during onion seed production. Polymer coating prolonged the release of pesticides. After 30 DAP, 557% and 1087% higher retention of fungicide and insecticide was observed in polymer coated bulbs over traditional method of bulb treatment. Onion bulb coating with polymer and 0.15 % fipronil + 0.25 % (carbendazim + mancozeb) showed significantly higher values for seed yield attributes, viz. productive scapes/plant (5.56), lower percent lodged scapes (21.16), seed yield/ plant (21.15 g) and seed quality attributes in comparison to control and traditional method of bulb treatment. Lowest percent disease index (36.39) was recorded in treatment- polymer coating + 0.15 % fipronil + 0.25 % (carbendazim + mancozeb) and lowest number of thrips/plant (5.14) was recorded in bulbs coated with polymer + 0.15 % fipronil + 500 ppm streptocyclin. Treating of onion bulbs with polymer is beneficial in increasing the efficacy of the applied pesticides, reducing the incidence of pest and diseases and enhancing seed yield and quality.
Simulation of strength difference in elasto‐plasticity for adhesive materials

Experimental evidence of certain adhesive materials reveals elastic strains, plastic strains and hardening. Furthermore, a pronounced strength difference effect between tension, torsion or combined loading is observed. For simulation of these phenomena, a yield function dependent on the first and second basic invariants of the related stress tensor in the framework of elasto‐plasticity is used in this work. A plastic potential with the same mathematical structure is introduced to formulate the evolution equation for the inelastic strains. Furthermore, thermodynamic consistency of the model equations is considered, thus rendering some restrictions on the material parameters. For evolution of the strain like internal variable, two cases are considered, and the consequences on the thermodynamic consistency and the numerical implementation are extensively discussed. The resulting evolution equations are integrated with an implicit Euler scheme. In particular, the reduction of the resulting local problem is performed, and for the finite‐element equilibrium iteration, the algorithmic tangent operator is derived. Two examples are presented. The first example demonstrates the capability of the model equations to simulate the yield strength difference between tension and torsion for the adhesive material Betamate 1496. A second example investigates the deformation evolution of a compact tension specimen with an adhesive zone. Copyright © 2005 John Wiley & Sons, Ltd.
Polynomial extrapolation from (1,1) to the unit disc

The problem of choice of nodes $\{ {x_k } \}_{k = 0}^n $ in $[ - 1,1]$ for polynomial extrapolation of continuous functions to the unit disc is discussed. For some specific sets of nodes which are of special interest in applications (the equally spaced points, the Chebyshev roots and extrema) the asymptotic estimates for the norm of the corresponding extrapolation operators are established. The problem of optimal choice of extrapolation nodes is discussed, and a lower bound for the minimum extrapolation norm is obtained. For $n = 2,3,4$ the optimal nodes are found explicitly, while for $4 < n \leqq 15$ the minimum extrapolation norm is computed numerically. These results show that the extrapolation operator based on the Chebyshev extrema is near-optimal.
Stimulation of ACE inhibitory and improving α‐amylase and α‐glucosidase and antioxidant activities of semi‐prepared and dry soup by incorporating with date kernel powder

Abstract Date kernel as a functional food component has a special importance due to its rich nutritional profile, low price, and ease of access. For this, in this research, the sub‐product was used for formulation of semi‐prepared dry soup (SPDS); the effect of adding 0 (S1 = control), 2 (S2), and 4 (S3) %w/w date kernel powder (DKP) on physicochemical, nutritional, and organoleptic properties and beneficial effects of SPDS samples were evaluated. The results revealed that S2 and S3 samples were different from the control sample in some physicochemical properties so that viscosity increased 1.27 and 1.52 times and a* raised 5.6 and 8.5 times, respectively, while L* decreased 0.94 and 0.88 times and b* reduced 0.92 and 0.8 times, respectively. The nutritional properties of S2 and S3 samples compared with the control sample improved. Also, differences were observed in the beneficial effects of S2 and S3 compared with the control sample as total polyphenol content (TPC) increased 1.06 and 1.11 times, respectively (p < .05); antioxidant activities (AA) of S2 and S3 samples were 8.04 and 6.01 mg/ml and angiotensin‐converting enzyme (ACE) inhibitory activities were measured to be 8.2 and 7.86 mg/ml, respectively; also, α‐amylase and α‐glucosidase inhibitory activities of S2 and S3 samples were observed 4.48% and 5.70%, and 4.59% and 6.36%, respectively. From the organoleptic aspect, S3 had the highest acceptability. Generally, it is concluded that with the addition of DKP (maximally 4%w/w) to SPDS formulation, a functional soup could be produced considering the rich nutritional profile of DKP.
High-energy spectroscopic study of the occupied and unoccupied 5 f and valence states in Th and U metals

X-ray photoemission spectroscopy and bremsstrahlung isochromat spectroscopy have been used to investigate the electronic density of states of metallic Th and U, below as well as above the Fermi level. In contrast to the discrete $4f$ levels observed in the rare earths, the $5f$ states in these metals are found to be delocalized and to form relatively narrow bands. The experimental spectra are compared to recent calculations of the density of states.
Identification, Screening, and Comprehensive Evaluation of Novel DPP-IV Inhibitory Peptides from the Tilapia Skin Gelatin Hydrolysate Produced Using Ginger Protease

Purpose: Inhibition of dipeptidyl peptidase-IV (DPP-IV) is an effective therapy for treating type II diabetes (T2D) that has been widely applied in clinical practice. We aimed to evaluate the DPP-IV inhibitory properties of ginger protease hydrolysate (GPH) and propose a comprehensive approach to screen and evaluate DPP-IV inhibitors. Methods: We evaluated the in vitro inhibitory properties of fish skin gelatin hydrolysates produced by five proteases, namely, neutral protease, alkaline protease, bromelain, papain, and ginger protease, toward DPP-IV. We screened the most potent DPP-IV inhibitory peptide (DIP) using liquid chromatography-tandem mass spectrometry (LC-MS/MS) coupled with in silico analysis. Next, surface plasmon resonance (SPR) technology was innovatively introduced to explore the interactions between DPP-IV and DIP, as well as the IC50. Furthermore, we performed oral administration of DIP in rats to study its in vivo absorption. Results: GPH displayed the highest degree of hydrolysis (20.37%) and DPP-IV inhibitory activity (65.18%). A total of 292 peptides from the GPH were identified using LC-MS/MS combined with de novo sequencing. Gly-Pro-Hyp-Gly-Pro-Pro-Gly-Pro-Gly-Pro (GPXGPPGPGP) was identified as the most potent DPP-IV inhibitory peptide after in silico screening (Peptide Ranker and molecular docking). Then, the in vitro study revealed that GPXGPPGPGP had a high inhibitory effect on DPP-IV (IC50: 1012.3 ± 23.3 μM) and exhibited fast kinetics with rapid binding and dissociation with DPP-IV. In vivo analysis indicated that GPXGPPGPGP was not absorbed intact but partially, in the form of dipeptides and tripeptides. Conclusion: Overall, the results suggested that GPH would be a natural functional food for treating T2D and provided new ideas for searching and evaluating potential antidiabetic compounds. The obtained GPXGPPGPGP can be structurally optimized for in-depth evaluation in animal and cellular experiments.
New method for the simulation of correlated K-distributed clutter

Correlated K distributions can be used to describe the clutter seen in coherent radar images. To test the performance of detection and classification algorithms in controlled clutter environments it is necessary to be able to produce accurate simulations of the clutter. For this reason, the simulation of correlated K distributed processes is of interest. A new method for simulating such processes is described which involves applying a variety of moving average filters to sequences of independent gamma distributed variables and summing the resulting sequences to obtain the desired autocorrelation properties. Using this technique, it is possible to match the desired single point statistics and correlation properties exactly although the procedure becomes increasingly complex as the correlation length increases. In common with all other currently available techniques for simulating correlated K distributions, the proposed scheme does not solve the problem of introducing anti-correlations which remains a subject of research. Simulations of both one- and two-dimensional processes are presented which demonstrate the accuracy of the technique.
Factorial Invariance in Multiple Populations

A multiple testing method for examining factorial invariance for latent constructs evaluated by multiple indicators in distinct populations is outlined. The procedure is based on the false discovery rate concept and multiple individual restriction tests and resolves general limitations of a popular factorial invariance testing approach. The discussed method controls the overall significance level and is associated with higher power than conventional multiple testing procedures. The procedure avoids the necessity to choose a reference variable in applications of latent variable modeling for testing factorial invariance. The outlined method permits location of factorial invariance violations, in addition to its examination for a given set of construct indicators, and is illustrated with a numerical example.
Effect of Focus on Form on Vocabulary Acquisition in Computer-Assisted Learning

This study analyzes the impact of focus on form on task-based contextual word acquisition to inform EFL vocabulary learning in a computer-assisted learning environment, with the goal of gaining a better understanding of the cognitive processes behind vocabulary acquisition. A classroom experiment was conducted at a high school in Fujian, China, to investigate two vocabulary acquisition settings for intermediate-level EFL students: maintenance rehearsal and elaborative rehearsal. The results showed that participants in the elaborative rehearsal group outperformed those who recited vocabulary in the maintenance rehearsal condition on the word recall and recognition test. The outcome also indicated that by practicing the input and output of the target words with contextual information in sentence rewriting, the focus-on-form impact of elaborative rehearsal promotes semantic and word form processing.
Exploring facilitators and barriers to long‐term behavior change following health–wellness coaching for stroke prevention: A qualitative study conducted in Auckland, New Zealand

Health–wellness coaching (HWC) has grown in popularity as a means of empowering individuals to take responsibility for their health behavior and make lifestyle changes to reduce their risk of stroke. Understanding the facilitators and barriers to long‐term behavior change is key if preventive strategies such as HWC are to be robust and effective. This study aimed to explore the experiences of people at risk of stroke after receiving HWC for stroke prevention, specifically the facilitators and barriers to long‐term behavior change from the perspective of study participants.
