     The paper shows how to estimate the three parameters of the generalized exponential Rayleigh distribution by utilizing the three estimation methods, namely, the moment employing estimation method (MEM), ordinary least squares estimation method (OLSEM),  and maximum entropy estimation method (MEEM). The simulation technique is used for all these estimation methods to find the parameters for the generalized exponential Rayleigh distribution. In order to find the best method, we use the mean squares error criterion. Finally, in order to extract the experimental results, one of object oriented programming languages visual basic. net was used

     The nuclear shell model was used to investigate the bulk properties of lithium isotopes (6,7,8,9,11Li), i.e., the ground state density distributions and C0 and C2 components of charge form factors. The theoretical treatment was based on supposing that the Harmonic-oscillator (HO) potential governs the core nucleons while the valence nucleon(s) move through Hulthen potential. Such assumptions were applied for both stable and exotic lithium isotopes. The HO size parameters (  and ), the core radii ( ) and the attenuation parameters (  and ) were fixed to recreate the available empirical size radii for lithium isotopes under study.
核壳模型用于研究锂同位素(6,7,8,9,11Li)的体态性质,即基态密度分布以及电荷形式因子的 C0 和 C2 分量。理论处理的基础是假设谐振子(HO)势支配核心核子,而价核子则通过赫尔岑势运动。这种假设适用于稳定的和奇异的锂同位素。HO尺寸参数(和)、核心半径()和衰减参数(和)被固定下来,以重现所研究的锂同位素的现有经验尺寸半径。

     Traditionally, real estate prices were determined based on demand and supply. As the real estate market was  unregulated and underdeveloped, brokers and real estate builders had an upper hand in determining the unit prices of residential houses in Abu Dhabi. A pricing gap was eventually noticed. This was a challenge. There is a delay in updating the real estate websites and portal information. Therefore, the need for accurate forecasting of prices has become urgent. With a variety of use case scenarios for machine learning concepts, this paper is dedicated to using the concepts of machine learning to predict the real estate prices of Aldar in the Abu Dhabi region, which comprises 511 residential units, 15 retail shops, and one community center. Decision tree, random forest, support vector machines, and K-nearest neighbors (KNN) algorithms were used to identify which one is better for forecasting these real estate prices. Comparing the generated models, the random forest is the best-performing model, followed by support vector regression, and the decision tree model is the least-performing model.
传统上,房地产价格是根据供求关系确定的。由于当时的房地产市场缺乏监管且不发达,经纪人和房地产建筑商在决定阿布扎比住宅单价方面占尽上风。最终,人们发现了价格差距。这是一个挑战。房地产网站和门户网站的信息更新存在延迟。因此,准确预测价格已成为当务之急。通过机器学习概念的各种用例场景,本文致力于使用机器学习概念来预测阿布扎比地区 Aldar 的房地产价格,该项目包括 511 个住宅单元、15 个零售商店和 1 个社区中心。本文使用了决策树、随机森林、支持向量机和 K-nearest neighbors (KNN) 算法,以确定哪种算法更适合预测这些房地产的价格。比较生成的模型,随机森林是表现最好的模型,其次是支持向量回归,而决策树模型是表现最差的模型。

     This study was carried out with the freshwater mussel Unio tigridis exposed to lead nitrate. The samples of water and mussels were collected from Qandil water resources situated in Qandil village at 36° 37' 39.55" north latitude and 44° 10' 51.80" east longitude, and it is  322 meters above sea level. In January 2022, rivers and aquariums water were tested for temperature,  pH, EC, TDS, DO, total alkalinity, total hardness, and calcium and magnesium ions. Studied organisms were exposed to variable concentrations of lead nitrate ranging from 0 to 900 ppm. The 96-h median lethal concentration (LC50) was measured and a comparison was made between the behavioural responses of the control and treatment groups. Also, the concentrations of lead in the experimental media, shell, and soft tissue of mussels were measured. A sample of mussels collected from aquarium was tested for biochemical markers, including acetylcholinesterase (AChE), Glutathione S-Transferase (GST), Catalase (CAT) and malondialdehyde (MDA). After 96 hours, the LC50 was estimated to be 782.7 ppm. The findings on behaviours revealed that lead slows down species' activities. Lead concentratiom increased within the mussel body as the water lead level decreased. The value of AChE was inversely related to lead concentration. However, GST, CAT and MDA increased with lead exposure.
本研究的对象是暴露于硝酸铅的淡水贻贝 Unio tigridis。水和贻贝样本采集自位于北纬 36°37' 39.55"、东经 44°10' 51.80"、海拔 322 米的 Qandil 村的 Qandil 水资源。2022 年 1 月,对河流和水族馆的水进行了温度、pH 值、EC 值、TDS、溶解氧、总碱度、总硬度以及钙镁离子的检测。研究生物暴露在不同浓度的硝酸铅中,浓度范围为 0 至 900 ppm。测量了 96 小时的中位致死浓度(LC50),并对对照组和处理组的行为反应进行了比较。此外,还测量了实验介质、贝壳和贻贝软组织中的铅浓度。从水族箱中采集的贻贝样本进行了生化指标检测,包括乙酰胆碱酯酶(AChE)、谷胱甘肽 S-转移酶(GST)、过氧化氢酶(CAT)和丙二醛(MDA)。96 小时后,半数致死浓度估计为 782.7 ppm。行为研究结果表明,铅会减缓物种的活动。随着水中铅含量的降低,贻贝体内的铅浓度也在增加。AChE 的值与铅浓度成反比。然而,GST、CAT 和 MDA 会随着铅暴露而增加。

     Antibiotics treat bacterial infections, whereas antiviral drugs treat viral illnesses. Antivirals are used to treat a variety of infectious diseases, including COVID-19 and influenza. The technique of reversed-phase high-performance liquid chromatography (RP-HPLC) provides more sensitivity and precision than other approaches, particularly spectrophotometric. This research seeks to develop a simple method for simultaneously quantifying acyclovir, amantadine, and oseltamivir in creams and capsules. The RP-HPLC method optimization and development for verifying the separation and quantification of three antiviral drugs included the investigation of the optimal buffer concentration, pH value, and acetonitrile content. On a C8 HyperClone BDS column, the RP-HPLC system with UV detection achieved separation (250 x 4.60 mm, 130A, and 5). The mixture of acetonitrile and acetate buffer as mobile phase gradient elution at a detection wavelength of 254 nm and 1 mL/min flow rate. The proposed method provided a linear range of 0.08-10.5, 0.06-4.5 and 0.02-14 μg/mL, as well as excellent validated values for LOD (0.0205, 0.0107, and 0.0083 μg/mL) and LOQ (0.0621, 0.0324 and 0.0251 μg/mL) with a coefficient of determination (r2) of the regression line of 0.9998, 0.9988, and 0.9994 for acyclovir, amantadine, and oseltamivir, respectively.

     This article aims to determine the time-dependent heat coefficient together with the temperature solution for a type of semi-linear time-fractional inverse source problem by applying a method based on the finite difference scheme and Tikhonov regularization. An unconditionally stable implicit finite difference scheme is used as a direct (forward) solver. While by the MATLAB routine lsqnonlin from the optimization toolbox, the inverse problem is reformulated as nonlinear least square minimization and solved efficiently. Since the problem is generally incorrect or ill-posed that means any error inclusion in the input data will produce a large error in the output data. Therefore, the Tikhonov regularization technique is applied to obtain stable and accurate results. Finally, to demonstrate the accuracy and effectiveness of our scheme, two benchmark test problems have been considered, and its good working with different noise levels.
本文旨在通过应用基于有限差分方案和 Tikhonov 正则化的方法,确定一种半线性时间分数反源问题的随时间变化的热系数和温度解。无条件稳定的隐式有限差分方案被用作直接(正向)求解器。通过优化工具箱中的 MATLAB 例程 lsqnonlin,逆问题被重新表述为非线性最小平方最小化,并得到高效求解。由于该问题通常是不正确的,这意味着输入数据中包含的任何误差都会在输出数据中产生较大误差。因此,我们采用了 Tikhonov 正则化技术,以获得稳定而准确的结果。最后,为了证明我们方案的准确性和有效性,我们考虑了两个基准测试问题,并在不同噪声水平下取得了良好的效果。

     Learning from imbalanced data has been a focus of studies for more than two decades of continuous development. Training data is considered imbalanced when the size of the positive (minority) class is neglected because of the large size of the negative (majority) class, in addition to the problem of deviating distributions of binary tasks. The appearance of big data brings new problems and challenges to the imbalance problem. Big Data announces the challenges with 5V: volume, velocity, veracity, value, and variety. This study relied on dividing the solution to the problem of data imbalance into three levels: data level, algorithm level, and hybrid approaches. First, the standard solutions for this problem that were proposed were mentioned, and in addition, the most important metrics adopted for measuring the classification efficiency of imbalanced data were identified. In this survey study, 27 studies were reviewed during the period 2015–2022, distributed according to the levels of treatment of the imbalance problem. They also reviewed the performance metrics that were used in these studies and the sources of the datasets to which these solutions were applied. The study makes it easier for researchers and scholars to see the solutions to addressing the problem of data imbalance and the hybrid approaches recently used for that, and to take advantage of them in improving the classification process.
经过二十多年的不断发展,从不平衡性数据中学习一直是研究的重点。除了二元任务的偏差分布问题外,当正向(少数)类的规模因负向(多数)类的规模大而被忽视时,训练数据就被认为是不平衡的。大数据的出现给不平衡问题带来了新的问题和挑战。大数据用 5V 宣告了挑战:数量、速度、真实性、价值和多样性。本研究将数据不平衡问题的解决方案分为三个层面:数据层面、算法层面和混合方法。首先,提到了针对这一问题提出的标准解决方案,此外,还确定了用于衡量不平衡数据分类效率的最重要指标。在这项调查研究中,对 2015-2022 年间的 27 项研究进行了回顾,这些研究按照处理不平衡问题的级别分布。他们还回顾了这些研究中使用的性能指标以及应用这些解决方案的数据集来源。这项研究使研究人员和学者更容易了解解决数据不平衡问题的方案和最近用于解决该问题的混合方法,并利用它们改进分类过程。

     The present work aims to detect the effects of gamma ray radiation emitted from Co-60 on several blood parameters (PCV, Hb, WBCs and  RBCs) of male chickens. Also, the potential antioxidant impact of grape seeds oil exposed to cold plasma  as a protective material to lower the damage caused by gamma ray was tested for a long time and low dose rate. Healthy male chickens were used in this study which had an age range of 2 to 3 months and  a weight range of 1.5 to 2 kg. Animals were kept in plastic cages (100 x 400  x 40 cm dimensions) within  humidity and temperature preserved at limited values. Four experimental groups were included; the first was the un-exposed control. The second group was administered with a dose of grape seed extract. The third group was exposed to gamma ray radiation only. The fourth group  was administered with a dose of grape seed extract  and irradiated with  gamma  waves. Forty male chickens   were used in this work as they were parted  and administered with the selected  doses. The control group was considered as the first group that contained  10 male chicken without  being exposed to waves of  gamma rays. The next group also contained  10 male chicken irradiated with 5 Gy/lh at  interval 7 hour/day for 20 days as second group. Another group contained 10 male chicken  and  was dealt with oil of grape seed  400 mg/kg wt) with orally administered dose for 20 days as third group. The fourth group contained 10 male chicken irradiated with 5 Gy/h at interval of 7 hour/day for 20 days and dealt with orally administered dose  (400 mg/kg wt)  of grape seed oil  for the same time. Overall groups (2-4), male chicken number became 30 used for 40.60 days at 7 hours per day. The schedule of work was achieved at 5 Gy/h of radiation equivalent dose with different exposure time for (20 and 40,60 days) on male chicken and at period 7 hours daily. The grape seed extract was bought from local market in Mosul City and filters from impure, as we found significant decrease in ratio of blood factors RBCs, WBCs, Hb and PCV with increasing of exposure time. This data changes with adding antioxidant materials as (grape seed oil) were the value of blood factors ratio enhancement by increasing the time of dose of these material compared with control group. The blood factors ratio of male chickens change with exposure time, with significant decrease by increasing exposure time, however, the protective material ( grape seed oil ) reduces the change in ratio % of the some blood factors compared with control group.
本研究旨在检测 Co-60 发出的伽马射线对雄鸡多项血液参数(PCV、Hb、白细胞和红细胞)的影响。此外,还测试了葡萄籽油作为一种保护性材料,在长时间、低剂量暴露于冷等离子体中对抗氧化的潜在影响,以降低伽马射线造成的损伤。本研究使用的是健康雄鸡,鸡龄为 2 至 3 个月,体重为 1.5 至 2 千克。动物被饲养在塑料笼(尺寸为 100 x 400 x 40 厘米)中,湿度和温度均保持在限定值内。实验分为四组:第一组为未接触对照组。第一组为未暴露对照组;第二组为服用葡萄籽提取物组;第三组为暴露伽马射线组。第三组只接受伽马射线辐射。第四组施用一定剂量的葡萄籽提取物,并接受伽马射线照射。这项研究使用了 40 只雄鸡,对它们进行了分群和选定剂量的给药。对照组被视为第一组,其中有 10 只雄鸡没有受到伽马射线照射。第二组也是 10 只雄鸡,每小时 5 Gy,每天间隔 7 小时,照射 20 天。第三组是 10 只雄鸡,口服葡萄籽油(400 毫克/千克体重),连续 20 天。第四组包括 10 只雄鸡,每天间隔 7 小时用 5 Gy/h 照射 20 天,同时口服葡萄籽油剂量(400 毫克/千克体重)。总体组别(2-4),雄鸡数量为 30 只,每天工作 7 小时,持续 40.60 天。工作安排是以 5 Gy/h 的辐射当量剂量和不同的照射时间对雄鸡进行照射(20 天和 40,60 天),每天照射 7 小时。葡萄籽提取物是从摩苏尔市当地市场上购买的,并经过过滤,因为我们发现随着照射时间的延长,血液中红细胞、白细胞、血红蛋白和 PCV 的比率会显著下降。与对照组相比,添加抗氧化剂(葡萄籽油)后,血液因子比率值会随着添加时间的增加而提高。雄鸡的血液因子比率随暴露时间而变化,暴露时间越长,比率越低,但与对照组相比,保护性材料(葡萄籽油)降低了某些血液因子比率%的变化。

     In this paper, we investigate the influence of the rotation and magnetic field on the peristaltic flow of the Bingham fluid in an asymmetric channel with a porous medium under the long wavelength and low Reynolds number approximation assumptions.                                                                                                                           The perturbation method and the Mathematica program for solving nonlinear partial differential equations are used to couple the momentum equations with the rotational and magnetic field equations. The fluid is considered to be subject to a magnetic field and to flow within a porous medium. Graphs are used to display expressions for speed, stress gradient, magnetic subject, current density, rotation impact, and drift function. The findings reveal that the rotation, density, permeability, coupling diversity, and non-dimensional wave amplitude all play significant roles in the phenomenon. The quantities flow has been tested for variant parameters. The impact of the Bingham, Hartman and Darcy numbers are also tested for different values to indicate the effect on the movement of flow fluid. The applications can be seen through many graphics. 
本文研究了在长波长和低雷诺数近似假设下,旋转和磁场对多孔介质不对称通道中宾汉流体蠕动流动的影响。 采用扰动法和 Mathematica 程序求解非线性偏微分方程,将动量方程与旋转方程和磁场方程耦合。流体被认为受到磁场作用,并在多孔介质中流动。图表显示了速度、应力梯度、磁主体、电流密度、旋转影响和漂移函数的表达式。研究结果表明,旋转、密度、磁导率、耦合多样性和非维度波幅在这一现象中都起着重要作用。量流已针对不同参数进行了测试。宾厄姆数、哈特曼数和达西数的影响也在不同数值下进行了测试,以显示对流动流体运动的影响。通过许多图形可以看到应用情况。
