The Effect of Planting Distances and Foliar Fertilization with Zinc on Yield and its Components of Soybean Crop

This study aims to examine the effect of planting distance and zinc foliar fertilization on soybean yield and its constituents; a field experiment was conducted in the summer of 2022 at the Hamidiyah research station of the College of Agriculture at the University of Anbar (var. Shaimaa). Three replicates of the experiment were conducted using a randomized complete block design (R.C.B.D) with a Split Plot layout. Zinc concentrations were varied across the main plots (0, 25, 50, and 75 mg Zn l-1), while planting distances (7, 14, 21, and 28 cm) were varied across the sub-plots, yielding densities of 190,000, 95,555, 63,333, and 47,777 plants ha-1, respectively. It was found that the number of pods per plant, the number of seeds per pod, the fertility rate, the total seed yield, and the biological yield were all maximized at a planting distance of 28 cm (low density), with averages of 149.1 pod plant-1, 2.90 seeds pod-1, 88.67%, 5.552 tons ha-1, and 15.94 tons ha-1, respectively. The average harvest index was 37.30% at a distance of 21 cm. However, the greatest average weight of 100 seeds was found at a distance of 7 cm (high density) (12.10 gm). The results also showed that a zinc concentration of 75 mg L-1 was optimal in terms of total seed yield (5.365 tons ha-1), the fertility rate (86.67%), the weight of 100 seeds (12.81 gm), and biological yield (16.33 tons ha-1). For most measures of yield and its components, there was no evidence of an effect of planting distance on zinc concentration.
Response of Vegetative Growth Traits of Several Soybean Cultivars to Spraying with the Growth Regulator Triacontanol (TRIA)

A field experiment was carried out in the fields of a farmer in the (Al-Boouda) area of Al-Karmah district - Al-Anbar Governorate during the summer season of 2022, to study the effect of spraying with several concentrations of the growth regulator (triacontanol) on the vegetative growth characters of soybean cultivars. The experiment was carried out in split plots arrangement, according to the RCBD design, with three replications. Four concentrations of growth regulator TRIA (0, 40, 50, 60) mg L−1 were allocated to the main plots, while three cultivars of soybean (Lee, Shama, Se-220) were allocated to the sub-plots. The result indicates that the Lee cultivar outperformed in most of the vegetative growth characters over the rest of the other cultivars such as the number of branches (6.91 branches Plant−1), plant height (98.08 cm), leaf area (38.62 cm2 Plant−1) and leaf area index (2.05). While the cultivar Shama was earlier to reached the stage of beginning flowering, and it took the least number of 57.00 days, compared to other cultivars. Whereas the cultivar Se-220 outperformed with highest mean of chlorophyll index in the leaves, reaching 37.43 spad. The results showed that the treatments sprayed with a growth regulator at a high concentration (60 mg L−1) were superior in most of the studied growth characteristics, and their average number of branches was (7.40 branches Plant−1), plant height (110.0 cm), and leaf area and leaf area index (44.87 cm2 Plant−1 and 2.38) respectively, and it needed the least number of days to reach the stage of the beginning of flowering at 58.33 days compared to the other concentrations. The results also indicated that the interaction between the study factors had a significant effect on most of the vegetative growth characters, where the Lee cultivar plant sprayed with a concentration of (60 mg L−1) of the growth regulator achieved the highest averages for several characters, including number of branches, plant height, and leaf area, while the two-way interaction did not affect significantly the number of days from planting to the beginning of flowering and the leaf area index.

Effect of Spraying with Brassinolide on Yield and its Components of Sesame Cultivars

To investigate the impact of brassinolide spraying on sesame yield and its components, a field experiment was conducted in the summer of 2022 in the Karma region of the Anbar Governorate. Three independent replicates of the experiment were conducted using a randomized complete block design (RCBD) with a split-plot layout. The cultivars (Sumer, Rafidain, Wadea, and Hadd) occupied the sub-plots, while the concentrations of brassinolide (0.0, 0.5, 1.0, and 1.5 mg L−1) comprised the main plots. The results showed that the Hadd cultivar was the best in terms of harvest index (22.9%), number of capsules produced by each plant (390.2 capsules plant-1), number of seeds produced by each capsule (96.42 seeds capsule−1), and total seed yield (2685.3 kg ha-1). Sumer was the only cultivar where the average weight of a thousand seeds was greater than any other (3.86 g). Brassinolide at a concentration of 1.5 mg L−1 resulted in an average of 273.9 capsules per plant, 95.50 seeds per capsule, 4.11 grams per thousand seeds, 2226.4 kilograms per hectare (kg) of seed output, 10.294 tons per hectare (t) of biological production, and a harvest index of 26.06%. The Hadd cultivar and a concentration of 1.5 mg L−1 had a significant interaction in terms of the number of capsules per plant, the number of seeds per capsule, the weight of a thousand seeds, total seed production (3017.9 kg ha−1), biological yield (13.707 tons ha−1) and harvest index.

Social Sustainability Initiatives (SSI) among Malaysian City Council: A Content Analysis of the Annual Report

Social sustainability is one aspect that contributes to the balance of sustainability goals, and its activities could impact and affect the subjects’ matters, including people, organisations, and communities. However, despite the rising social issues, research on the social dimension of sustainability is limited and needs more analysis, especially the efforts taken by the local authorities. Thus, this triggers the discovery of local authorities’ social sustainability initiatives (SSI) practices, mainly city council. This study aims to provide a benchmark on Social Sustainability Initiatives (SSI) currently practised by Malaysian City Councils. This study’s objectives are to identify the city councils’ SSI practices from the annual report; the SSI disclosed in annual report by determining the most prominent SSI practices among local authorities. Thus, this research adopted a qualitative method using the content analysis technique. The annual reports for the years 2018, 2019 and 2022 were used for this study for the respective City Councils. As a result, it was discovered that only ten (10) SSI themes through 39 initiatives were practised, with 14 most prominent SSIs determined. Hence, the Malaysia Local Authority has shown a commitment to preserving and protecting social sustainability and demands more promotion on what Malaysia City Councils have done in promoting sustainability.
A critical fractional Choquard–Kirchhoff problem with magnetic field

In this paper, we are interested in a fractional Choquard–Kirchhoff-type problem involving an external magnetic potential and a critical nonlinearity [Formula: see text] [Formula: see text] where [Formula: see text] with [Formula: see text], [Formula: see text] is the Kirchhoff function, [Formula: see text] is the magnetic potential, [Formula: see text] is the fractional magnetic operator, [Formula: see text] is a continuous function, [Formula: see text], [Formula: see text] is a parameter, [Formula: see text] and [Formula: see text] is the critical exponent of fractional Sobolev space. We first establish a fractional version of the concentration-compactness principle with magnetic field. Then, together with the mountain pass theorem, we obtain the existence of nontrivial radial solutions for the above problem in non-degenerate and degenerate cases.
Optimal Convergence for Distributed Learning with Stochastic Gradient Methods and Spectral-Regularization Algorithms

We study generalization properties of distributed algorithms in the setting of nonparametric regression over a reproducing kernel Hilbert space (RKHS). We first investigate distributed stochastic gradient methods (SGM), with mini-batches and multi-passes over the data. We show that optimal generalization error bounds can be retained for distributed SGM provided that the partition level is not too large. We then extend our results to spectral-regularization algorithms (SRA), including kernel ridge regression (KRR), kernel principal component analysis, and gradient methods. Our results are superior to the state-of-the-art theory. Particularly, our results show that distributed SGM has a smaller theoretical computational complexity, compared with distributed KRR and classic SGM. Moreover, even for non-distributed SRA, they provide the first optimal, capacity-dependent convergence rates, considering the case that the regression function may not be in the RKHS.
Blasius Problem with Generalized Surface Slip Velocity

This paper considers the classical problem of the steady boundary layer flow past a semi-infinite flat plate first considered by Blasius in 1908 with generalized surface slip velocity. Numerical solutions are obtained by solving the nonlinear similarity equation using the bvp4c function from MATLAB for several values of the slip parameters.
Determination of the Azimuthal Asymmetry of Deuteron Photodisintegration in the Energy Region E{sub {gamma}} = 1.1 - 2.3 GeV

Deuteron photodisintegration is a benchmark process for the investigation of the role of quarks and gluons in nuclei. Existing theoretical models of this process describe the available cross sections with the same degree of success. Therefore, spin-dependent observables are crucial for a better understanding of the underlying dynamical mechanisms. However, data on the induced polarization (P{sub y}), along with the polarization transfers (C{sub x'} and C{sub z'} ), have been shown to be insensitive to differences between theoretical models. On the other hand, the beam-spin asymmetry {Sigma} is predicted to have a large sensitivity and is expected to help in identifying the energy at which the transition from the hadronic to the quark-gluon picture of the deuteron takes place. Here, the work done to determine the experimental values of the beam-spin asymmetry in deuteron photodisintegration for photon energies between 1.1  2.3 GeV is presented. The data were taken with the CLAS at the Thomas Jefferson National Accelerator Facility during the g13 experiment. Photons with linear polarization of ~80% were produced using the coherent bremsstrahlung facility in Hall B. The work done by the author to calibrate a specific detector system, select deuteron photodisintegration events, study the degree of photon polarization, and finally determine the azimuthal asymmetry and any systematic uncertainties associate with it, is comprehensively explained. This work shows that the collected data provide the kinematic coverage and statistics to test the available QCD-based models. The results of this study show that the available theoretical models in their current state do not adequately predict the azimuthal asymmetry in the energy region 1.1  2.3 GeV.
Mobility management in hybrid ad‐hoc networks and the Internet environment

The integration of mobile ad‐hoc networks (MANETs) with the Internet provides flexible and multi‐hop communication capability in hybrid wired and wireless networks. Existing architectures for integrating these networks use Mobile IP and ad‐hoc routing protocols with fixed gateways. In this paper, we propose a mobility management scheme based on a mobile gateways (MGs) architecture. We designed a buffering mechanism for micro‐ and macro‐mobility management in hybrid networks. The performance of mobility management with optimized handover (MM‐OH), optimized handover with prediction (MM‐OHP) and forced handover (MM‐FH) are evaluated using simulation. Our simulation results show that a buffering mechanism coupled with the hybrid gateway discovery results in a higher packet delivery ratio for MM‐OH and MM‐OHP compared with the MM‐FH scheme. The MM‐OHP scheme has a lower number of handovers compared with the MM‐OH scheme. Moreover, the simulation experiments reveal that the speed of the MG has a relatively higher impact on performance than the speed of mobile nodes. Copyright © 2007 John Wiley & Sons, Ltd.
Robust estimation and model identification for longitudinal data varying-coefficient model

ABSTRACT It is well known that M-estimation is a widely used method for robust statistical inference and the varying coefficient models have been widely applied in many scientific areas. In this paper, we consider M-estimation and model identification of bivariate varying coefficient models for longitudinal data. We make use of bivariate tensor-product B-splines as an approximation of the function and consider M-type regression splines by minimizing the objective convex function. Mean and median regressions are included in this class. Moreover, with a double smoothly clipped absolute deviation (SCAD) penalization, we study the problem of simultaneous structure identification and estimation. Under approximate conditions, we show that the proposed procedure possesses the oracle property in the sense that it is as efficient as the estimator when the true model is known prior to statistical analysis. Simulation studies are carried out to demonstrate the methodological power of the proposed methods with finite samples. The proposed methodology is illustrated with an analysis of a real data example.

MULTICRITERIA INTEGER LINEAR PROGRAMS

We settle the computational complexity of fundamental questions related to multicriteria integer linear programs, when the di- mensions of the strategy space and of the outcome space are considered fixed constants. In particular we construct: 1. polynomial-time algorithms to exactly determine the number of Pareto optima and Pareto strategies; 2. a polynomial-space polynomial-delay prescribed-order enumera- tion algorithm for arbitrary projections of the Pareto set; 3. an algorithm to minimize the distance of a Pareto optimum from a prescribed comparison point with respect to arbitrary polyhedral norms; 4. a fully polynomial-time approximation scheme for the problem of minimizing the distance of a Pareto optimum from a prescribed comparison point with respect to the Euclidean norm.
Generalization Bounds for Magnitude-Based Pruning via Sparse Matrix Sketching

In this paper, we derive a novel bound on the generalization error of Magnitude-Based pruning of overparameterized neural networks. Our work builds on the bounds in Arora et al. [2018] where the error depends on one, the approximation induced by pruning, and two, the number of parameters in the pruned model, and improves upon standard norm-based generalization bounds. The pruned estimates obtained using our new Magnitude-Based compression algorithm are close to the unpruned functions with high probability, which improves the first criteria. Using Sparse Matrix Sketching, the space of the pruned matrices can be efficiently represented in the space of dense matrices of much smaller dimensions, thereby lowering the second criterion. This leads to stronger generalization bound than many state-of-the-art methods, thereby breaking new ground in the algorithm development for pruning and bounding generalization error of overparameterized models. Beyond this, we extend our results to obtain generalization bound for Iterative Pruning [Frankle and Carbin, 2018]. We empirically verify the success of this new method on ReLU-activated Feed Forward Networks on the MNIST and CIFAR10 datasets.
A Bayesian analysis for the bivariate geometric distribution in the presence of covariates and censored data

Abstract In this paper, we introduce a Bayesian analysis for bivariate geometric distributions applied to lifetime data in the presence of covariates and censored data using Markov Chain Monte Carlo (MCMC) methods. We show that the use of a discrete bivariate geometric distribution could bring us some computational advantages when compared to standard existing bivariate exponential lifetime distributions introduced in the literature assuming continuous lifetime data as for example, the exponential Block and Basu bivariate distribution. Posterior summaries of interest are obtained using the popular OpenBUGS software. A numerical illustration is introduced considering a medical data set related to the recurrence times of infection for kidney patients.
Damaging Southerly Winds Caused by Barrier Jets in the Cook Strait and Wellington Region of New Zealand

AbstractStrong southerly winds regularly occur in the Cook Strait region of New Zealand. Occasionally, these winds are strong enough to cause severe damage to property and threaten human life. One example of a storm containing such winds is the “Wellington Storm,” which occurred on 20 June 2013. For this case, wind speeds in Cook Strait were stronger than those observed or forecast elsewhere in the storm. Even though wind speeds of this intensity are rare, storms affecting New Zealand with central pressures equal to the Wellington Storm (~976 hPa) are not uncommon. Numerical experiments have been carried out to investigate the possible reasons for the exceptional damaging southerly winds (DSWs) occurring in this storm. Analyses of the simulations showed that DSWs in Cook Strait for this event were actually barrier jets, not gap winds as they appeared. The strength of barrier jets in Cook Strait is sensitive to the precise location of the storm center. This explains the uncommon occurrence of DSWs in Cook .
