Communication and information technologies have facilitated the rapid adoption of electronic medical records, leading to patient privacy and data security concerns. Blockchain technology offers a promising solution to address these issues. However, scalability remains a significant challenge for blockchain-based electronic health records (EHR) systems. In this study, we aimed to develop and evaluate an EHR management system based on blockchain technology. Therefore, we propose a management model based on organizations and user roles and implemented it using Hyperledger Fabric and the InterPlanetary File System (IPFS). The blockchain consists of three channels: one for patient registration and EHR retrieval and two additional channels ded

The present study used the solar radio flux (F10.7 cm) and the sunspot number (SSN) created throughout five years, beginning in December 2019 and ending in December 2023, for the solar cycle 25. The number of sunspots and the solar radio flux were measured monthly using data from the WDC-SILSO, Royal Observatory of Belgium, Brussels. A five-year link between the two variables was constructed, marking the start of the solar cycle 25 (2019 to 2023) years. Understanding their relationship and the degree to which they impact solar activity, which affects terrestrial and space technology, is also important. For sunspots, the highest value reached (127.6) in 2023, while the lowest value (1.8) was attained in 2019. With time, the value increase

In the study of urban changes in the Dora area of Baghdad between 2013, 2018, and 2023, analyses revealed a significant increase in residential areas and a reduction in desert areas based on a shortest-distance classification for land use study. The findings highlight quantitative and qualitative shifts, with the first period (2013-2018) showing a 29.25% increase in residential space and the subsequent period (2018-2023) an additional 11.52% rise, reflecting a clear pattern of urban expansion. This transformation has impacted the area’s environmental balance, as the reduction of desert land coupled with increased pollution from the Dora Refinery and other urban activities has led to notable environmental consequences. Furthermore, econ

The goal of this study is to introduce a new concept on a lifting module. Let M be a unitary left  R-module, and let R be any ring with one. M is called 〖Rad〗_R*-lifting for short (R^*-lifting) for any A ≤ M, there are some submodule B of A that is M=B⨁B_1, B_1≤M and A∩B_1 ≪_R*B_1.We prove some characterization of this class of modules.

The relation between this concept and other modules related with it are presented. In addition, FI-R^*-lifting was introduced as fallows: if for any submodule fully invariant A≤ M , there is some submodule D of M that is M=D

The primary goal of this research is to obtain an approximate solution to the  Hirota-Satsuma coupled KdV equations with the lowest error rate, specifically when the time derivative is associated with a fraction and subject to specific initial conditions. In this work, two basic concepts are presented, the fractional Caputo derivative of order α>0 and the Sumudu Transform (ST), along with some inherent properties of this transformation. To address the problem at hand, a hybrid approach was adopted using numerical methods, combining the Sumudu Transform and the Adomian Decomposition Method (ADM). The Adomian Decomposition Method, as it is known, works to deal with complex nonlinear boundaries that are difficult to deal with directly.

In this study, new generalized derivative and integral operators are introduced, stemming from the newly developed new generalized Caputo variable order fractional derivatives (NGCVFDs). Utilizing these operators, a numerical method is devised to address variable order fractional differential equations (VOFDEs). The solutions of VOFDEs are approximated using shifted Legendre polynomials (SLPs) as basis vectors, and the derivative operational matrix of SLPs is extended to a generalized derivative operational matrix in the context of NGCVFDs. The efficiency of the numerical method is assessed through various test examples. Additionally, the outcomes of the proposed method are compared with existing methodologies in the literature. The vari

In this article, we propose for a linear regression model a new biased estimator aimed at mitigating the impact of multicollinearity on the estimation of unknown parameters. The idea of the proposed estimator is constructed as a combination of the unbiased ridge estimator (URR) and the ordinary ridge regression estimator (ORR). The statistical properties for the new estimator and other existing estimators are found. We demonstrate the advantages of this new estimator using the mean squared error criterion, showing that its mean squared error does not exceed that of either the URR or ORR individually. This simulation study supports these theoretical results, revealing that the new estimator outperforms both the URR and ORR. This suggests

In the current research, we dealt with the numerical method of Newtonian flow through the conical nozzle under incompressibility constraint by using a Taylor Galerkin Pressure Correction (TGPC) finite element algorithm. The governing equations that describe such problem consist of time-dependent equations for the conservation of momentum and continuity equation. The essential feature of this investigation is concerned with the effect of outlet dimeter of nozzle, length of the cylinder and conical angle on the component of solution. There, we found that the levels of velocity and pressure are increased as these parameters increase, it was found that the maximum velocity increased from 38.39 to 1254.67 when the ratio  increased from 1 to
