Abstract

Objective. To develop and in vivo demonstrate threadlike wireless implantable neuromuscular microstimulators that are digitally addressable. Approach. These devices perform, through its two electrodes, electronic rectification of innocuous high frequency current bursts delivered by volume conduction via epidermal textile electrodes. By avoiding the need of large components to obtain electrical energy, this approach allows the development of thin devices that can be intramuscularly implanted by minimally invasive procedures such as injection. For compliance with electrical safety standards, this approach requires a minimum distance, in the order of millimeters or a very few centimeters, between the implant electrodes. Additionally, the devices must cause minimal mechanical damage to tissues, avoid dislocation and be adequate for long-term implantation. Considering these requirements, the implants were conceived as tubular and flexible devices with two electrodes at opposite ends and, at the middle section, a hermetic metallic capsule housing the electronics. Main results. The developed implants have a submillimetric diameter (0.97 mm diameter, 35 mm length) and consist of a microcircuit, which contains a single custom-developed integrated circuit, housed within a titanium capsule (0.7 mm diameter, 6.5 mm length), and two platinum–iridium coils that form two electrodes (3 mm length) located at opposite ends of a silicone body. These neuromuscular stimulators are addressable, allowing to establish a network of microstimulators that can be controlled independently. Their operation was demonstrated in an acute study by injecting a few of them in the hind limb of anesthetized rabbits and inducing controlled and independent contractions. Significance. These results show the feasibility of manufacturing threadlike wireless addressable neuromuscular stimulators by using fabrication techniques and materials well established for chronic electronic implants. Although long-term operation still must be demonstrated, the obtained results pave the way to the clinical development of advanced motor neuroprostheses formed by dense networks of such wireless devices.

Abstract
We report mode structure measurements of coherent ion cyclotron emission (ICE) and sub-cyclotron modes on DIII-D. Through a dedicated experiment, we aimed to characterize a variety of modes via the upgraded ICE diagnostic in both L- and H-mode plasmas. In the L-mode plasmas, autopower spectrum peaks at harmonics of the ion cyclotron frequency f
ci were observed and are localized in the core of the plasma. Sub-cyclotron modes (f ∼ 0.5f
ci) were also observed in L-mode plasmas when the toroidal magnetic field strength was lowered from B
T = 2.17 T. In H-mode plasmas, many ICE harmonics localized to the plasma edge were observed, with some exceeding the nominal ICE diagnostic bandwidth of f ∈ [0, 100] MHz. Polarization estimates made using an orthogonal pair of vertical and horizontal magnetic pickup loops on the outer wall of the machine indicate that ICE and sub-cyclotron modes have compressional polarization at the plasma edge, the latter being consistent with simulation efforts for comparable DIII-D plasmas. For all modes, the same harmonics are observed on both the centerpost and outer wall loops, indicating that ICE is poloidally extended. Finally, toroidal mode numbers were calculated using three outer wall loops for both core ICE and sub-cyclotron modes in L-mode plasmas. The sub-cyclotron case served as a benchmark for our calculation method, with measured numbers of n ∈ [−24, −18] roughly agreeing with heuristic estimates of n ∈ [−20, −13]. Core ICE mode numbers were measured to be n ∈ [−10, 5], which is comparable to measurements made on other machines.

Published: August 2022

Abstract
In this research, the parameters and reliability of the Alpha Power Rayleigh distribution were estimated by each of the moments method, the modification moment method, the percentile method and the maximum likelihood estimation method. The simulation technique was used to generate the data required for estimation and for different sample sizes and its replicate to 1000. The mean square error criterion was used to compare the obtained results. In general, the results of the estimators show that maximum likelihood estimation method is the best in estimating each of the parameters and the reliability function.

A comparative study to choose the appropriate growth model to forecast COVID-19 cases in Iraq
Authors: Hussain Jassim N. 
Published: August 2022

Abstract
COVID-19 infection cases forecasting is a process of estimating future values based on historical data which is playing an important role in health decision making in various fields. Daily infection cases of COVID-19 can be considered as a time series represent the growth of the number of infected persons in a population. Consequently, the growth models may be used to forecast any population growth such as population of infected people with the Covid-19 virus. The popular models of growth such as logistic, log-logistic, Gompertz, Weibull and Richards models are useful to describe the growth of many phenomena like an epidemic and the spread of the number of infected people. The main objective of this paper is to choose a successful growth model after comparing these models to make good use of the current data on COVID-19 in Iraq to better understand the spread of this disease and to forecast the future daily infection cases. AIC, BIC and other goodness of fit criteria and daily infection cases in Iraq for the period from 1st Jan. 2021 until 30th April 2021 were used to compare these models and choose the successful model. The results of fitting these model show that the appropriate models are Weibull type 1 and log-logistic with five parameters models, and the predicted numbers of infected cases are near the actual numbers of infected cases.

Published: August 2022

Abstract
Because direct relationships are difficult to uncover, we may not be able to find a link between two different scientific directions. This question prompted us to look for a connection between partition theory and mapping, which we will describe as the initial steps toward convergence with other types of mapping. For this, we must present an integrated vision of the merging process between them, as well as how we will be able to contact them precisely.

Abstract
Statistical analyzes include a study of many societies’ characteristics that are data collection, organization, analysis, and analysis to get the aim with easy-to-understand diagrams and analytical drawings in return. In this paper, we will try to shed light on the most popular statistical methods, analysis of variance, and familiarize the reader with its types and how to choose the most appropriate data used during the various experiments. This paper deals with a brief outline of the species, and a practical application of communication data using statistical methods, where we found from the obtained results that the sensor provided for sensing low ranges has high sensitivity and high linearity in addition to the possibility of using it in extreme environments, which makes it a good choice for use in medical fields. As for the mathematical analysis, the analysis of the variance test supports the practical results, as there are no differences between the first and second groups (probability = 0.1832) nor between the second and third groups (probability = 0.1043), but there are statistically significant differences between the first and third groups (probability = 0.0054). The preference belongs to the third group (C) and as the best response on run 18 = 430.

The stereographic generalized inverse Weibull distribution
Authors: Abid Salah Hamza 
Published: August 2022

Abstract
When the unit circle is taken as a sample space, the circular data manifest in different aspects of real life. Minh and Farnum (2003) used a stereographic projection to generate new probability distributions on real line [1]. Here, we present an asymmetric distribution called Stereographic generalized inverse Weibull distribution (SGIWD) to represent circular data with focus on the inverse Stereographic Projection. The graph of probability density function is done. We consider here some statistical properties of SGIW distribution, survival and reverse hazard functions, the rth raw moments function, trigonometric moments, stress-strength reliability model, Tsallis, Renyi Shannon entropies and the Kullback–Leibler divergence measure. A simulation study is conducted to evaluate the behavior of the maximum likelihood method to estimate parameters of SGIWD.
An Efficient Variational Homotopy Transform Method for Solving Schrodinger Equation
Authors: Jawad Huda , Al-Fayadh Ali 
Published: August 2022

Abstract
This paper presents a new methodology for solving Schrödinger equation based on the variational iteration method and the Kashuri-Fundo transform. The Lagrange multiplier is computed using the Kashuri - Fundo transform. This approach helps in avoiding the difficulties often appearing in finding Lagrange multiplier and the complicated integration used in Variational Iteration Method, as well as it does not need to use the convolution theorem of the transform. Furthermore, the Homotopy Perturbation Method is used to dealing with the nonlinear terms arising in the problems where the He’s polynomials are calculated. The proposed method emphasises the existence of the obtained solution in the absence of any linearization, discretization, or hypothesis. The suggested method’s compactness and reliability are demonstrated by numerical examples

A New Convex Controller for Stabilizing of Two Symmetrical Logistic Maps
Authors: Al-Saidi Nadia M. G. , Salih Shaymaa H. 
Published: August 2022

AbstractIn this paper, we focused on the coupled logistic map, which is a system of two symmetrically identical single logistic maps. The complicated dynamics of the generated system, which has a wide range of dynamical behavior, grant it much attention for many applications. First, the existence and uniqueness of this system are investigated, where the analytical technique is utilized to find the parametric condition for the local asymptotic stability of its fixed points. It can be obviously seen that it undergoes Niemark-Sacker and Hopf bifurcation in a small neighborhood of the unique positive fixed point and invariant circle. This has been proven based on bifurcation theory and the center manifold theorem. The behavior of this system is stabilized using two conventional controlling methods, the OGY and the pole-placement. As well as, a new control method is proposed to make such stabilization more easier. The numerical simulations are utilized to demonstrate the analytic results.
