Biometrics is a growing field, which permits identification of individuals by means of unique physical features. Electroencephalography (EEG)-based biometrics utilizes the small intra-personal differences and large inter-personal differences between individuals’ brainwave patterns. However, traditional EEG-based subject identification techniques frequently require a lot of electrodes, making it cumbersome and impractical for real-world applications. In this research, we suggest a method for subject identification using lightweight convolutional neural networks (CNN) while minimizing the number of electrodes. We propose a approach for subject identification in EEG that aims to minimize the number of electrodes while leveraging the power of CNNs. To achieve this, we divide the conductive electrodes of the cortex into (64, 32, 16) distinct groups. By exploiting the automatic feature extraction capabilities of CNNs, we process the EEG data from each electrode group individually. Remarkably, Electrodes (16) achieved an accuracy rate of 97.72%, 32 odd electrodes achieved an accuracy rate of 98.16%, while 32 even electrodes achieved an accuracy rate of 99.3%, and electrodes (64) achieved an accuracy rate of 95.47%. These results clearly demonstrate the robustness and efficacy of our method in accurately identifying individuals based on their EEG patterns. By decreasing the number of electrodes and capitalizing on the distinctive patterns captured by the electrode groups, our method provides a practical and efficient solution for subject identification in EEG.
生物统计学是一个不断发展的领域,它允许通过独特的物理特征识别个人。基于脑电图(EEG)的生物识别技术利用了个人脑电波模式之间微小的人内差异和巨大的人际差异。然而,传统的基于脑电图的主体识别技术往往需要大量的电极,因此在实际应用中非常麻烦且不实用。在这项研究中,我们提出了一种使用轻量级卷积神经网络(CNN)进行主体识别的方法,同时最大限度地减少电极数量。我们提出了一种在脑电图中进行受试者识别的方法,旨在最大限度地减少电极数量,同时利用卷积神经网络的强大功能。为此,我们将皮层的传导电极分为 (64, 32, 16) 个不同的组。利用 CNN 的自动特征提取功能,我们对每个电极组的脑电图数据进行单独处理。值得注意的是,电极(16)的准确率达到了 97.72%,32 个奇数电极的准确率达到了 98.16%,而 32 个偶数电极的准确率达到了 99.3%,电极(64)的准确率达到了 95.47%。这些结果清楚地表明了我们的方法在根据脑电图模式准确识别个人方面的稳健性和有效性。通过减少电极数量和利用电极组捕捉到的独特模式,我们的方法为脑电图中的受试者识别提供了一种实用高效的解决方案。

The association between innovation, performance, and systems of internal control has been extensively explored in research. However, none of this research has been conducted in Moroccan public organizations. This paper aimed to analyze the impact of internal control on the innovation and performance of these organizations using a causal and quantitative methodology. A sample of 187 public organizations was utilized. The data collected through a questionnaire were analyzed using the structural equation modeling approach (PLS 4). The results demonstrate that internal control significantly influences the performance and innovation of public organizations in the Moroccan context, where empirical literature is scarce. For future research, it is recommended to investigate the relationship between prospector-type strategy, innovation, and organizational performance.

Banks play a crucial role as financial intermediaries in advancing economies. Increasing market share is a top priority for all banks in today's fiercely competitive market. To achieve this, banks are expected to enhance their efficiency, which boosts their competitive capacity and helps decision-makers identify areas for development. This paper introduces an extended fuzzy TOPSIS approach that incorporates integral values to assess banking performance. Our method includes the averaging and normalization of decision-makers assigned ratings and weights, ensuring a standardized scale for comparison. Subsequently, we create membership functions for the ultimate fuzzy evaluation values of alternatives using interval arithmetic for fuzzy numbers. We employ a novel fuzzy number ranking method based on integral values to streamline the aggregation of fuzzy numbers to defuzzify the weighted ratings.

在经济发展中,银行作为金融中介机构发挥着至关重要的作用。在当今激烈的市场竞争中,提高市场份额是所有银行的当务之急。为实现这一目标,银行应提高效率,从而增强竞争能力,帮助决策者确定发展领域。本文介绍了一种包含积分值的扩展模糊 TOPSIS 方法,用于评估银行绩效。我们的方法包括对决策者分配的评分和权重进行平均和归一化处理,以确保比较尺度的标准化。随后,我们使用模糊数的区间算术为备选方案的最终模糊评估值创建成员函数。我们采用一种新颖的基于积分值的模糊数排序方法,简化模糊数的聚合,对加权评分进行去模糊化处理。最后,我们引入了接近系数,通过计算备选方案与正负理想方案的距离来确定备选方案的排序顺序。为了说明我们提出的方法的有效性和适用性,我们介绍了一个应用实例。

The male reproductive system relies on the proper production of sperm. Spermatogenesis is a complex process that calls for the cooperation of many different elements. The presence of pro-inflammatory cytokines such as interleukin 1 beta (IL-1β), interleukin 2, and interleukin 15 in the male reproductive tract may be responsible for the manifestation of physiological processes in the testes, epididymis, and sperm of the male reproductive system. However, The present study aimed to determine the effect of Coronavirus disease (COVID-19) on the concentration levels of  IL-1β, interleukin 2, and interleukin 15 in males. Moreover, to assess its impact on the hormone. A total of the n=95 clinical samples from the infertile patients confirmed COVID-19 patients involved the analysis of serum or plasma samples from 95 patients to measure levels of Testosterone hormone, IL15, IL-1B, and IL-2 by using an ultrasensitive enzyme-linked immunoabsorbent. The results showed a significant increase (p<0.05) of IL-1B, IL-15 and a decrease in IL-2  level in infertile; also,  testosterone evaluated in the serum and plasma of SARS-CoV-2 patients showed a positive connection between the level of hormone and IL-1B, IL-15, While negatively related with IL-2 patients infected with coronavirus compared with non-infected infertile patients. Male individuals with COVID-19 who experience infertility exhibited a combination of various factors that are linked to reduced testosterone hormone levels. These factors include advancing age, obesity, and cytokine alteration; there is an observed increase in IL-1B and IL-15 levels and a decrease in IL-2 concentration in these patients.
男性生殖系统依赖于精子的正常生成。精子生成是一个复杂的过程,需要许多不同因素的合作。男性生殖道中存在白细胞介素 1β(IL-1β)、白细胞介素 2 和白细胞介素 15 等促炎细胞因子,这可能是睾丸、附睾和精子等男性生殖系统生理过程表现的原因。然而,本研究旨在确定冠状病毒病(COVID-19)对男性体内 IL-1β、白细胞介素 2 和白细胞介素 15 浓度水平的影响。此外,为了评估其对激素的影响。通过使用超灵敏酶联免疫吸附器,对 95 名确诊为 COVID-19 的不育患者的血清或血浆样本进行分析,以测量睾酮激素、IL15、IL-1B 和 IL-2 的水平。结果显示,不育患者的 IL-1B、IL-15 水平明显升高(p<0.05),IL-2 水平下降;同时,SARS-CoV-2 患者血清和血浆中的睾丸激素评估结果显示,与未感染不育患者相比,感染冠状病毒患者的睾丸激素水平与 IL-1B、IL-15 呈正相关,而与 IL-2 呈负相关。患有 COVID-19 的男性不育患者表现出与睾丸激素水平降低有关的各种因素的综合作用。这些因素包括年龄增长、肥胖和细胞因子的改变;在这些患者中观察到 IL-1B 和 IL-15 水平的升高和 IL-2 浓度的降低。

Wetland sediments can become contaminated with contaminants that pose a risk to plants and animals and are present in groundwater and fresh surface water entering the wetland. The current study aims to detect PCB contaminants in the sediments of the Al-Hamar Marsh in southern Iraq from the winter season of 2021 until the fall season of 2022 during the day from five stations in the Al-Hamar Marsh, which are (1 - Al-Harir, 2 - Al-Mashab 3 - Al-Nakara, 4 - Baraka 1, 5 - Baraka 2). PCBs were analyzed by GC-MASS. The results showed that the highest rate of PCBs concentrations was (2.84) in the winter season and the lowest rate was (0.14 ng/g d. w). The concentrations of PCBs at the study stations ranged (2.34 ng/g d.w - 3.9 ng/g d.w) during the winter season. (0.01 ng/g d.w-3.7 ng/g d.w) during the spring, (0.01 ng/g d.w- 1.46 ng/g d.w) in the summer, and (0.02 ng/g d.w -5.78 ng/g d.w) during the summer. In the fall, the soil texture was measured and the results showed that the sediments of the Al-hammar marsh were silty clay deposits. This study is a first of its kind in the region and could be give available information and used as a baseline study in the futures.
湿地沉积物可能受到污染物的污染,这些污染物对动植物构成风险,并存在于进入 湿地的地下水和地表淡水中。本研究旨在从 2021 年冬季到 2022 年秋季的白天,从 Al-Hamar 沼泽的五个站点(1 - Al-Harir、2 - Al-Mashab 3 - Al-Nakara、4 - Baraka 1、5 - Baraka 2)检测伊拉克南部 Al-Hamar 沼泽沉积物中的多氯联苯污染物。对多氯联苯进行了 GC-MASS 分析。结果显示,冬季多氯联苯浓度最高(2.84),最低(0.14 纳克/克干重)。研究站的多氯联苯浓度在冬季为(2.34 纳克/克干重 - 3.9 纳克/克干重)。(春季(0.01 ng/g d.w-3.7 ng/g d.w),夏季(0.01 ng/g d.w-1.46 ng/g d.w),夏季(0.02 ng/g d.w-5.78 ng/g d.w)。在秋季,对土壤质地进行了测量,结果显示阿尔-哈马尔沼泽的沉积物为淤泥质粘土沉积物。这项研究在该地区尚属首次,可以提供可用信息,并作为期货的基线研究。
