Introduction: Diabetes is an independent risk factor for coronary heart disease worldwide. But few data exist in our developing countries. The objective of this study was to study the particularities of STEMI in diabetic patients in Dakar. Methodology: It was a retrospective, multicenter and descriptive study, carried out over a period of 12 months from 19 September 2019 to 19 September 2020 in four cardiology centers in Dakar. Included was any diabetic patient admitted for STEMI. Data analysis was done with the SPSS (Statistical Package for Sciences Socials) software. Results: A total of 87 diabetic patients were included, for a prevalence of 29.7%. The average age of patients was 60 years. The predominance was male with a sex ratio of 1.1. Diabetes was mostly type 2 (99%) and most patients were on oral antidiabetics (56%). Glycemic imbalance was noted in 24.1% of patients. The associated cardiovascular risk factors were hypertension (51%), dyslipidemia (51%) and physical inactivity (41.4%). Chest pain was typical in 76% of cases. The average time between onset of pain and first medical contact was 47 hours. The electrocardiogram had reached mainly the anterior (25%) and inferior (27%) territories with necrosis Q waves in 37.9% of cases. The coronary angiography was done for 63 patients and found one hundred and twenty-three significant lesions distributed in three-vessel (48%), single-vessel (33%) and two-vessel (14%) disease. Percutaneous coronary intervention (PCI) was performed in 37 patients (42.2%) and thrombolysis in 7 patients. The evolution was favourable in most cases (82%). The reported complications were: 4 cardiogenic shocks, 3 rhythm disorders, 2 conduction disorders and 2 strokes. Four patients had died during hospitalization, for a hospital mortality of 4.59%. Conclusion: STEMI in diabetics are diagnosed with considerable delay in Dakar. The coronary involvement is severe. Their support under optimal. Improving management requires a multidisciplinar

The Cenozoic alkaline volcanism of the Senegalo-Mauritania sedimentary basin presents an episodic long-lasting volcanic activity from the Eocene-Oligocene boundary up to the Quaternary. Two volcanic episodes are usually distinguished on stratigraphical grounds: a Miocene one and a Quaternary one separated by a period of quiescence of several million years corresponding to the main phase of lateritic weathering. The Tertiary lavas are highly silica-undersaturated alkaline rocks ranging from nephelinites to basanites. They contain nepheline and fassaite-type clinopyroxene in their mineralogy. The Quaternary lavas are more evolved with Hy-normative in comparison to the Tertiary ones;they are composed of basanites and medium to coarser-grained dolerites. The distribution of the REE and other incompatible elements are typical of alkaline lavas with generally strong LREE enrichment without significant Eu anomaly. The Cenozoic Cap-Vert lavas have OIB (oceanic islands basalts)-affinities as shown by their relatively radiogenic Nd and unradiogenic Sr characters closed to the HIMU-OIB. This suggests a HIMU-type end member in the magma sources which is fairly comparable to those erupted in the Canaries and Cape Verde archipelagoes during the same period.

Detailed work on Quaternary volcanism has been carried out in the Mermoz and Fann sectors of western Senegal. In the Mermoz sector, the main emission zone is a collapsed crater located at the intersection of three major fractures: NE-SW, NW-SE and N-S. The lithological succession in this Mermoz sector comprises, from bottom to top: 1) a substratum with at its base Eocene limestones on which lie Quaternary sands surmounted by stratified tuffs;2) a vesicular ball dolerite which deforms the stratified tuffs;3) a dark early breccia;4) two generations of basanites: the first is vesicular, the second non-vesicular;5) a clear intermediate breccia and finally 6) a late breccia. The Fann sector contains several emission zones, most of which are currently located in the ocean. The lavas may have reached the coast through E-W and NE-SW faults. The lithological succession includes from bottom to top: 1) scoria-rich early volcanic breccias;2) a first generation of non-vesicular mesocrate dolerite (D1);3) a second generation of melanocrate vesicular dolerite (D2);4) basanites and finally 5) a late breccia. The geochemical characteristics of the lavas studied are compatible with a very enriched and very deep magmatic source of the garnet lherzolite type located in the lower mantle. The magma from this source would have risen in the form of mantle plumes through major NE-SW and E-W faults in a continental intraplate context.

秀丽隐杆线虫的神经系统结构表明,在机器人领域应用动物智能是一种简单的方法。本文提出了一种基于Pybullet框架的四足蚂蚁运动控制方法。虽然增广随机搜索算法已经取得了显著的效果,并成功地应用于各种形式的大规模任务中,但仍有一些有待改进的地方。本文针对四足蚂蚁机器人在连续时间环境下的控制问题,提出了一种将随机搜索算法与蠕虫神经网络相结合的控制方法,该方法使蚂蚁的运动具有了一定的可解释性。本文主要研究内容如下:首先,对蠕虫(秀丽隐杆线虫)进行了介绍,给出了与蠕虫相关的背景,主要描述了蠕虫运动学假说。本文还讨论了仿生学在四足机器人领域的应用。其次,介绍了强化学习的理论和技术,并利用仿生蠕虫神经网络对蚂蚁四足机器人进行了训练。第三,我们回顾了机器人中四足动物的进化历程。描述了四足蚂蚁机器人在PyBullet环境中的结构和运动的数学模型。第四,以蚂蚁四足机器人为例,说明了抽头提取电路的功能和映射过程。蚂蚁四足机器人由111个输入和8个输出组成,为了控制蚂蚁四足机器人,我们需要对它的8个输出进行控制。首先,我们利用一个线性层,将111个输入变量映射为连续的2个变量,然后将它们输入抽头提取电路(TW电路)的2个感测神经元,最后再利用一个线性层,将2个运动神经元的神经电位映射到8个控制输出,即完成了对蚂蚁四足机器人的8个输出的控制。最后,我们通过观察PyBullet蚂蚁控制过程中的结果,展示了蠕虫神经网络的可解释性,蠕虫神经网络作为一种简单自然的人工神经网络结构,表现出了较好的性能。实验结果表明,将增广随机搜索算法与蠕虫网络相结合形成的神经电路策略比单独使用增广随机搜索算法的蚂蚁控制具有更好的性能。

Introduction: At university, habits, particularly eating habits, can negatively impact well-being. This study aimed to describe lifestyle habits and dietary diversity among medical students. Methodology: This was a cross-sectional, descriptive study, carried out at the UFR 2S of the University Gaston Berger from May 23 to June 3, 2023. The collection tool focused on sociodemographic characteristics, lifestyle habits and dietary diversity. Statistical analyzes were carried out using R software. Results: A total of 471 students participated in this study. Which corresponds to a participation rate of 89.2% with a M/F sex ratio of 1.66. The age of participants, varying from 18 to 32 years, had a median of 23 years and a mean of 22.4 years with a standard deviation of 2.2 years. Among the participants, 67.2% skipped breakfast, and 28.5% did not practice any physical sports activity. Alcohol and tobacco were consumed by 2.5% and 0.6% of participants, respectively. The most consumed foods were starchy foods (97.5% of men and 98.4% of women);and the least consumed were dark green leafy vegetables (21.9% of men and 15.1% of women) and offal (16.9% of men and 11.9% of women). The dietary diversity score was low for 31.9% of men and 28.7% of women. Conclusion: Certain lifestyle habits (skipping breakfast, dining late at night, lack of sports practice) of Medicine students at UGB can prove deleterious to their well-being. These students are at risk of developing several deficiencies in terms of food groups that are underrepresented in their diet. Awareness sessions on good lifestyle habits and diet would be relevant recommendations for improving the health of these students.

Stereo-electroencephalography （SEEG） is the main investigation method for pre-surgical evaluation of patients suffering from drug-resistant partial epilepsy. SEEG signals reflect two types of paroxysmal activity： ictal activity and interictal activity or interictal spikes （IS）. The relationship between IS and ictal activity is an essential and recurrent question in epiletology. In this paper, we present a distributed and parallel architecture for space and temporal distribution analysis of IS, based on a distributed and collaborative methodology. The proposed approach exploits the SEEG data using vector analysis of the corresponding signals among multi-agents system. The objective is to present a new method to analyze and classify IS during wakefulness （W）, light sleep （LS） and deep sleep （DS） stages. Temporal and spatial relationships between IS and seizure onset zone are compared during wakefulness, light sleep and deep sleep. Results show that space and temporal distribution for real data are not random but correlated.

Sensitivity analysis is important in understanding the effect of each climatic input variable on the variation of the evapotranspiration which is a significant element for hydrological modelling, irrigation programs, and water resources management. This study investigates the responses of evapotranspiration to the variation of maximum and minimum temperature, solar radiation, wind speed and maximum and minimum relative humidity. Daily data from 1998 to 2012 of eight stations are used. For each climatic variable, a variation of 5% up to ±25% was performed in order to evaluate the sensitivity of the evapotranspiration to the input variables. Results show that evapotranspiration is more sensitive to the variation of solar radiation, maximal temperature and wind speed, respectively.

This study aims to determine the factors related to HIV-positive status in people aged 15 to 49 years of age in the commune of Niagha in Goudomp. The study was descriptive and analytically cross-cutting and had taken place in a release of 2018. The data was collected on anonymous questionnaires and then analyzed using R software after entering with Epi 7 software. Bivariate analyses and logistical modelling have been used to investigate the factors associated with HIV status. The sample included 400 people, and a participation rate of 100% was obtained in relation to the administration of the questionnaire. For the detection of HIV infection, 318 people agreed to do so, a proportion of 79.7%. The average age of the respondents was 27.8 years with a standard deviation of 9.1 and extremes of 15 to 49 years. 21.5% of respondents were under 20 years of age, the median was 26 years. With 58.8% of women, the sex ratio (M/F) was 0.7. In this study, 11.5% of respondents did not believe in the existence of HIV infection, 92.0% were sexually active, and 40.5% had sex with casual partners. The main places for casual sex were cultural events (84.0%), weekly markets (53.1%), religious events (27.8%) and during travel (22.8%). Among them, only 20 respondents, or 12.3%, declared that they systematically protect themselves with a condom during these occasional sexual relations. This wearing of condoms was found in 20.7% of singles and 10.7% of married couples having casual sex. In this study, 60.0% of the respondents declared that they had paid for sex, although this practice is not cited in income-generating activities. Non-consensual sex was found in 6.5% of the respondents. In this study, 319 people agreed to be tested for HIV, or 79.7% of the sample. HIV infection was found in 19 people, 6.0% seroprevalence, with 16 cases of HIV 1 infection and three cases of HIV 2 infection. Several risk behaviors were found in this study. However, none of them had a statistically significant
