Processing of Multichannel Sliding Spotlight SAR Data with Large Pulse Bandwidth and Azimuth Steering Angle

Azimuth multichannel synthetic aperture radar (SAR) working in the sliding spotlight mode can effectively achieve ultrahigh resolution and wide swath imaging. However, multichannel sliding spotlight SAR echoes with large pulse bandwidth and azimuth steering angle are difficult to reconstruct and process due to the large range frequency-dependent Doppler centroid varying frequency support. To resolve this problem, two azimuth preprocessing approaches both based on the range frequency-dependent deramping strategy are proposed in this article. In both approaches, echoes are handled by a range frequency-dependent azimuth deramping function at first, which assign the signal measurements to unambiguous Doppler frequencies. Afterward, in the first preprocessing approach, azimuth multichannel raw data can be reconstructed and combined before azimuth upsampling in the conventional two-step preprocessing technique. The other way to handle the deramped multichannel raw data is the modified full aperture azimuth multichannel sliding spotlight reconstruction approach, which embeds azimuth multichannel reconstruction into azimuth convolution between the deramped raw data and the selected range frequency-dependent azimuth deramping function. Furthermore, the azimuth data in the second approach should be resampled to obtain a uniform azimuth sampling interval. Computational complexity and effects on the following imaging algorithm of both approaches are analyzed and compared. Simulation results validate the proposed two azimuth multichannel preprocessing approaches.
Effect of Organic Manures Application on Soil Physicochemical Properties of Coarse-textured Ultisol and Okra Productivity in Nsukka, Southeastern Nigeria

Background: The greenhouse and field studies were carried out to assess the effect of different rates of poultry manure (PM), pig slurry (PS) and the recommended NPK fertilizer on some soil physico-chemical properties and okra yield of coarse-textured Ultisols in Nsukka, southeastern Nigeria. Methods: The PM and PS were applied at three different rates (10, 20 and 40 t ha-1) as well as no amendment as control and the recommended NPK fertilizer (300 kg/ha) and replicated five times. Soil and agronomic data collected were analyzed for variance (ANOVA) using Genstat 4.0. Result: The PM and PS significantly (p less than 0.05) improved soil pH, soil organic matter, available phosphorous, total nitrogen, aggregate stability, mean weight diameter, bulk density, porosity and saturated hydraulic conductivity in greenhouse and field studies. Significant improvement in CEC was obtained in the field study. The PM and PS significantly (p less than 0.05) improved agronomic parameters e.g. plant height, number of leaves, biomass weight and yield of okra than the control. Poultry manure showed its superiority over other amendments in improving soil and agronomic properties. The study recommended 20 t ha-1 of PM and 40 t ha-1 of PS for sustainable soil and optimum productivity of okra in Nsukka, southeastern Nigeria.
Structural and Optical Properties of Zirconia Nanoparticles by Thermal Treatment Synthesis

Zirconium dioxide nanoparticles with monoclinic blended structure were successfully synthesized by thermal treatment method using zirconium (IV) acetate hydroxide as the metal precursor, polyvinylpyrrolidone as the capping agent, and deionized water as a solvent. The chemicals were mixed and stirred to form a homogeneous solution and hereafter directly underwent calcination to attain the pure nanocrystalline powder, which was confirmed by FTIR, EDX, and XRD analyses. The control over the size and optical properties of nanoparticles was achieved through changing in calcination temperatures from 600 to 900&#-80;C. The obtained average particle sizes from XRD spectra and TEM images showed that the particle size increased with increasing calcination temperature. The optical properties which were investigated using a UV-Vis spectrophotometer showed a decrease in the band gap energy with increasing calcination temperature due to the enlargement of the particle size. These results prove that, by eliminating drying process (24źh) in the present thermal treatment method, size-controlled zirconia nanoparticles were conveniently manufactured with a reduction of synthesize time and energy consumption, suitable for large-scale fabrication.
Consistency and Asymptotic Normality of the Maximum Likelihood Estimator in GaGLM

The Gamma distribution based generalized linear model (<inline-formula> <tex-math notation="LaTeX">$Ga$ </tex-math></inline-formula>GLM) is a kind of statistical model feasible for the positive value of a non-stationary stochastic system, in which the location and the scale are regressed by the corresponding explanatory variables. This paper theoretically investigates the asymptotic properties of maximum likelihood estimates (MLE) of <inline-formula> <tex-math notation="LaTeX">$Ga$ </tex-math></inline-formula>GLM, which can benefit the further interval estimates, hypothesis tests and stochastic control design. First, the score function and the Fisher information matrix for <inline-formula> <tex-math notation="LaTeX">$Ga$ </tex-math></inline-formula>GLM are derived. Then, the Lyapunov condition is derived to ensure the asymptotic normality of the score function normalized by the Fisher information matrix. Based on this condition, the asymptotic normality of the MLE of <inline-formula> <tex-math notation="LaTeX">$Ga$ </tex-math></inline-formula>GLM is proven. Finally, a numerical example is given to testify the asymptotic properties obtained in the research. The numerical results indicate that the MLE of <inline-formula> <tex-math notation="LaTeX">$Ga$ </tex-math></inline-formula>GLM converged to a normal distribution as the number of sample measurements increased.
Design for high-quality factor of piezoelectric-on-silicon MEMS resonators using resonant plate shape and phononic crystals

Piezoelectric-on-silicon MEMS resonator is very well known for its compatibility with CMOS integrated circuit technology. However, its quality factor (Q) is highly affected by acoustic energy loss through the supporting structures. In this study, a resonator with butterfly-like round edge resonating plate structure and deploying properly designed PnC arrays on the tether and the anchoring boundaries are proposed to scale up the quality factor by effectively reducing the energy loss. The finite element analysis simulation results reveal that the proposed topologies can efficiently change the displacement field in the resonating plate and reduce the anchor loss. Consequently, an unloaded quality factor Qu of the conventional resonator is raised from 29 899 to 51 503 (butterfly-like round edge resonating structure), 83 349 (Phononic crystal on the tether) and 83 899 (Phononic crystal on the anchor), representing 1.7 folds, 2.78 folds and 2.8 folds improvement respectively.
Development of a PID-Fuzzy controller in the water level control of a pressurizer of a nuclear reactor

It is well known that safety in the operation of nuclear power plants is a primary requirement because a failure of this system can result in serious problems to the environment. A nuclear reactor has several systems that help keep it in normal operation, within safety margins. Many of these systems operate in the control of variable quantities in the primary circuit of a reactor. However, nuclear reactors are nonlinear physical systems, and this introduces a complexity in the control strategies. Among several mechanisms in the thermal-hydraulic system of a reactor that actuate as a controller, the pressurizer is the component responsible for absorbing pressure variations that occur in the primary circuit. This work aims at the development of a PID controller (Proportional Integral Derivative) based on fuzzy logic to operate in a pressurizer of a nuclear Pressurized Water Reactor. A Fuzzy Controller was developed using the process of fuzzification, inference, and defuzzification of the variables of interest to a pressurizer, then this controller was coupled to a PID Controller building a PID Controller, but oriented by Fuzzy logic. Subsequently, the PID-Fuzzy Controller was experimentally validated in a Simulation Plant in which transients like those in a PWR were conducted. The PID parameters were analyzed and adjusted for better responses and results. The results of the validation were also compared to simple controllers (on / off).

Highly‐tunable and wide stopband microstrip bandpass filters

This paper presents the design of a highly‐tunable single‐ended and balanced filter with improved upper stopband performance. The proposed filters are designed using a spurline and a U‐shaped stepped impedance resonator (SIR) with a varactor diode connected to the open‐circuited end. A spurline is introduced in both designs to achieve wide stopband performance by suppressing the higher‐order modes. The proposed filters have high tunable ranges (single‐ended: 2.35‐3.99 GHz; balanced: 2.39‐4 GHz), low insertion losses (IL) (single‐ended: 0.07‐0.2 dB; balanced: 0.21 to 1.1 dB) and wide upper stopband performance (single‐ended: 3.79f1 with a rejection level higher than 20 dB; balanced: 3.79f1 with a rejection level higher than 20 dB). Performance of both filters are experimentally validated by comparing the experimental results with the simulated ones. Both filters can cover most of the fifth‐generation (5G) wireless communication bands with different biasing voltages (capacitance). When both filters are compared with state‐of‐the‐art filters, the proposed filters are found to achieve high tunable ranges with low IL and wide upper stopband performance.
Why we can’t talk openly about race: The impact of race and partisanship on respondents’ perceptions of intergroup conversations

Conversations about race-specific issues with interracial conversation partners can be important to combat prejudice and foster mutual understanding. Using a national U.S. sample of 201 Black Democrats, 199 Black Republicans, 200 White Democrats, and 200 White Republicans, this study examined the role that race and partisanship play in individuals’ desire to have political discussions about race-specific topics with racial outgroups. Findings indicate that Blacks in general expected more negative outcomes of race talk with racial outgroups, and Republicans were more likely to attempt to avoid interracial conversations about race. However, these findings were qualified by an interaction between race and partisanship such that White Democrats anticipated fewer negative outcomes from cross-race conversations about race than all other subgroups, and Black Democrats expected more negative outcomes than all other subgroups. Black and White Republicans did not differ from one another and fell roughly between the two Democratic subgroups. Nonetheless, it was White Republicans who were most likely to want to avoid race-specific conversations with cross-race discussion partners, rating significantly more avoidant than Black Republicans and White Democrats, but not Black Democrats.
Portuguese Version of the Kansas Marital Satisfaction Scale: Preliminary Psychometric Properties

Abstract Marital satisfaction is considered a core dimension to understand marriage quality, influencing individual and family well-being. The Kansas Marital Satisfaction Scale (KMSS) is one of the most used instruments to assess this dimension. This study presents the psychometric properties of the KMSS Portuguese version through two studies. In Study 1, 145 couples (parents of school-aged children) completed the KMSS, and the Co-parenting Questionnaire and Inventory of Attachment in Childhood and Adolescence. The one-factor structure of the KMSS was supported (CFA), and an invariance analysis showed the same structure for males and females. Preliminary evidence supported concurrent and discriminant validity, and high reliability (α = .97) was observed. In Study 2, the factor structure was replicated in an extended sample (361 couples) and invariance tests showed a similar one-factor structure for two stages of the family life cycle (children 6–12 and 13–18 years). Results indicated the measure’s suitability for research in the Portuguese context; however, further study is needed for its clinical use.
Construction of finite tight frames via singular value decomposition

Finite tight frames are used widely for many applications. An important problem is to construct finite frames containing specified elements as needed in real world applications. In this paper we provide a stable method for that purpose. We establish an identity for constructing equi-norm tight frames from the specified elements and present a method for generating equi-norm tight frames explicitly from the outcome of the singular value decomposition of the matrix of the given elements. Under certain conditions, the number of columns of the unit-norm tight frames generated by our method reaches the minimum bound, improving a result in the literature. Finally, we illustrate our method through a numerical example.
Effectiveness of web-based intervention for reducing problematic alcohol use in Korean female college students

ABSTRACT Objective This study applies and evaluates the effectiveness of the online-based program Brief Empowerment Program for Alcohol Use Monitor among female university students in South Korea. Methods Participants were current drinkers scoring three or higher on the AUDIT-C test. A total of 70 students participated in the experimental group and 113 students in the control group. The study used a pretest-posttest control group design and an eight-week web-based intervention with a repeated-measures analysis of variance. Results The experimental group displayed a significant decrease (11.7%) of the AUDIT-C score, indicating the intervention’s effectiveness. Conclusions The present study emphasizes the implementation of effective interventions to reduce heavy drinking. The significant effect of the intervention is related to the characteristics of the web-based program. A web-based program is more appropriate than an in-person intervention for female college students with problematic drinking when considering Korean society’s context due to concerns about stigma.
Influence of hydrophobic and hydrophilic filler particles on thermal expansion and cooking loss in meat protein gels

Summary This study aimed to determine the eﬀect of replacing hydrophobic fat-based particles with hydrophilic inert glass particles at concentrations 10%, 25% and 40% on expansion, contraction and cooking loss of meat protein gels during heat treatment up to 85 ° C. Incorporating glass particles resulted in gel expansion (up to 22.3% (cid:1) 2.8% at 40%) independent of the particle concentration during heat treatment in an open system, while an increased fat-particle content provoked a gel shrinkage (up to − 6.5% (cid:1) 2.2% at 40%). At high ﬁller concentrations, expansion and shrinkage were inversely correlated with cooking loss: The highest fat and glass particle ﬁller concentration exhibited the lowest cooking loss (20.1% (cid:1) 0.5% for glass particles and 21.7% (cid:1) 0.2% for fat particles) despite the observed extensive structural changes, which was related to particle hydrophilicity, gel composition and structural rearrangement. These results will be helpful to design particle-ﬁlled composite meat gels with diﬀerent types of particles. This groundbreaking research showed the beneﬁts of incorporating hydrophilic ﬁllers into meat gels. The ﬁllers reduced the number of water channels and microfractures. This in depth-study provides very useful insights into how matrix-ﬁl-ler interactions alter the gel structure. This study provided insightful results for the understanding of fat stabilization in meat gels. It proposed that physical entrapment is the major factor for fat stabilization. This excellent research provided new insights into the fat and water holding mechanism in meat batters and proposed a strong capillary

The obtained cyclopropane fused pyrrolidines can be readily converted to other N-heterocycles with potential synthetic and biological interests.
AN IMPROVED GREY WOLF OPTIMIZATION-BASED LEARNING OF ARTIFICIAL NEURAL NETWORK FOR MEDICAL DATA CLASSIFICATION

Grey wolf optimization (GWO) is a recent and popular swarm-based metaheuristic approach. It has been used in numerous fields such as numerical optimization, engineering problems, and machine learning. The different variants of GWO have been developed in the last 5 years for solving optimization problems in diverse fields. Like other metaheuristic algorithms, GWO also suffers from local optima and slow convergence problems, resulted in degraded performance. An adequate equilibrium among exploration and exploitation is a key factor to the success of meta-heuristic algorithms especially for optimization task. In this paper, a new variant of GWO, called inertia motivated GWO (IMGWO) is proposed. The aim of IMGWO is to establish better balance between exploration and exploitation. Traditionally, artificial neural network (ANN) with backpropagation (BP) depends on initial values and in turn, attains poor convergence. The metaheuristic approaches are better alternative instead of BP. The proposed IMGWO is used to train the ANN to prove its competency in terms of prediction. The proposed IMGWO-ANN is used for medical diagnosis task. Some benchmark medical datasets including heart disease, breast cancer, hepatitis, and parkinson's diseases are used for assessing the performance of IMGWO-ANN. The performance measures are described in terms of mean squared errors (MSEs), classification accuracies, sensitivities, specificities, the area under the curve (AUC), and receiver operating characteristic (ROC) curve. It is found that IMGWO outperforms than three popular metaheuristic approaches including GWO, genetic algorithm (GA), and particle swarm optimization (PSO). Results confirmed the potency of IMGWO as a viable learning technique for an ANN.

Mudharabah Linked Waqf: Inovasi Model Pembiayaan Berkelanjutan untuk UMKM

This study aims to formulate an innovative financing model and sustainable business assistance through the mudharabah linked waqf scheme. The method used is descriptive qualitative in the form of reviewing scientific journals, books, official news, reports and related regulations which are analyzed by content analysis. Mudharabah linked waqf is an innovation and integration of financing to Micro, Small, and Medium Enterprises (MSMEs) where the composition of the source of funds comes from commercial funds and cash waqf funds managed by Koperasi Syirkah Berkah Bersama (KSBB) through a collaboration with Indonesian Muslim Entrepreneurs Community (KPMI) chapter Surabaya. Funds will be channeled to low-risk MSME projects recommended by KPMI Surabaya with a duration of fewer than six months. The surplus of cash waqf will be distributed to social, education, economy, and da’wah activities in the form of sustainable business development and fiqh muamalah assistance by KPMI Surabaya, and the rest distributed as an incentive to reduce Murabaha margins for startups. Risk mitigation is carried out through collateral requirements, guarantor, incentive-compatible contract applications to determine cash flows and related parties in the project, as well as post-project financial audits. This model has implications for strengthening the roles of KSBB and KPMI Surabaya in encouraging literacy, inclusion, and innovation in deepening sustainable Islamic financial products, in order to strengthen the economy of ummah in the real sector
