Access to electricity in Mali remains one of the lowest in the world, with a national rate of 51% marked by significant disparities between urban and rural areas. This study assesses the territorial distribution of electricity coverage provided by national electrification services. The methodology is based on the use of geographic information systems combined with multi-criteria decision support analysis to identify the localities concerned. The data used includes municipal demographic statistic...

The mining project of MCC Jiangxi Copper Aynak Mining Co., Ltd. in Afghanistan is of strategic and economic importance. However, the region’s long-term conflict has disrupted the local talent development system, creating a severe shortage of skilled mining professionals. Additionally, local universities’ outdated curricula and lack of practical training have hindered recruitment efforts. The company’s current talent selection system primarily focuses on professional skills and work experience, n...

We present a refined framework for the holographic emergence of linearized gravity, building upon earlier ideas that spacetime dynamics originate from entanglement entropy and quantum error-correcting codes. By employing explicit calculations in conformal field theory toy models and the Wald entropy formalism, we derive the linearized Einstein equations as consistency conditions of the first law of entanglement entropy. We further establish quantitative measures to characterize the resilience of...

In the digital economy era, talent has become a core strategic resource for organizations, but the issue of rising employee turnover rates and job burnout is becoming increasingly prominent, and the impact of family responsibilities on career development urgently needs to be further explored. This study is based on the work family boundary theory and resource conservation theory, and constructs a theoretical model of family responsibility perception, work embeddedness, and employee subjective ca...

Background: Left ventricular hypertrophy (LVH) is an early marker of cardiac involvement and a predictor of heart failure and mortality. This study aimed to determine the incidence of LVH, describe its progression trajectory after initiation of antiretroviral therapy (ART), and identify risk factors for LVH among people living with HIV (PLHIV). Methods: This retrospective cohort study included 154 adults living with HIV who were followed at the University Clinics of Kinshasa between 2000 and 200...

This study examined the nature of job-related stress and the role of technology in reducing workplace stress among employees in upscale hotels. It used a descriptive cross-sectional survey design. A structured questionnaire with 32 closed-ended items was used to collect data from 60 members of staff across eight hotels in the Sekondi-Takoradi Metropolis. The data was analyzed using descriptive statistics. It was found that hotel employees experienced moderately high stress, with job insecurity b...

Climate variability remains an urgent challenge to food security in sub-Saharan Africa, particularly for smallholder farmers who depend on rain-fed agriculture. Better access to collective and institutional support through climate education and access to credit can strengthen their ability to respond effectively to the challenges posed by climate variability. This paper delves into the socioeconomic factors influencing farmers’ ability to adapt to climate variability in Kuria East Sub-County, Mi...

Based on the concept of engineering education accreditation, the analysis of course objective achievement is a key approach to evaluating student learning outcomes. The traditional assessment method for the “Digital Electronic Technology” course is relatively simplistic. This paper takes the “Digital Electronic Technology” course at Guilin University of Technology as a reform pilot, reconstructing the course evaluation system and objective achievement analysis method. By combining qualitative an...

Aim: Amniotic fluid embolism (AFE) is a potentially lethal obstetric emergency with a high maternal mortality rate. Our report details two successful cases of patients who developed non-overt disseminated intravascular coagulation (DIC) following cesarean section, likely induced by AFE, and were managed using a bundle transfusion strategy prior to experiencing massive postpartum hemorrhage. Methods: An aggressive bundle transfusion strategy was initiated upon early laboratory evidence of coagulo...

The canonical affinity-threshold model of thymic T-cell selection posits that thymocyte fate is determined by TCR-pMHC integrated affinity. However, this model fails to explain high thymocyte deletion rates, diverse TCR affinities in mature repertoires, and precise CD4/CD8 lineage commitment mechanisms. We propose a novel Differential TCR Signaling Model wherein the functional TCR signal is a relative comparison: TCRβ signal strength relative to a dynamic TCRα-derived self-reference threshold (T...
