HIV-infected patients with working memory deficit exhibit greater cortical thickness in the left frontal cortex compared to those without such deficits. This study suggests that the increased cortical thickness may be due to inflammatory responses or increased synaptic contacts related to HIV infection. The findings align with previous research on brain abnormalities in HIV-infected patients and provide insights into the neurobiology of HIV-related brain injury. Limitations include the lack of a HIV-negative control group and the inability to assess differences between treated and untreated patients.

The first commercial 3D bioprinter, capable of replicating cellular tissue and potentially generating entire organs, is set to revolutionize the field of organ transplants. Developed by Gabor Forgacs of the University of Missouri and commercialized by Organovo, the technology has already achieved significant milestones, including printing vascular tissue and nerve grafts. Fred Davis of Invetech emphasizes the need for substantial federal investment to accelerate progress. While the technology holds promise, it requires further testing before becoming a viable option for human transplants. The article draws parallels to the space race, suggesting that with adequate funding, complex and transplantable organs could be created in a relatively short time.

The study explores the use of cutting-edge reality capture technologies, including terrestrial laser scanners (TLS) and close-range photogrammetry (CRP) based on unmanned aerial vehicles (UAVs), to create accurate 3D models of railway bridges. The methodology integrates both active and passive vision systems to capture comprehensive data, resulting in a detailed 3D as-is model of the bridge. This model is compared to a 3D as-designed model to detect geometric deviations, revealing slight deviations with a global average of 9 mm. The study highlights the efficiency and accuracy of these technologies in bridge inspection and monitoring, emphasizing their potential for early detection of structural issues and cost-effective maintenance.

The article presents a novel AI-based methodology for detecting corrosion in large-scale industrial buildings using UAVs. The study developed a high-resolution image database and employed the Mask R-CNN framework for instance segmentation. The methodology demonstrated high precision and recall rates, proving effective even under complex conditions. The research highlights the potential for significant cost savings and enhanced safety in infrastructure management.

The article criticizes the Dominican Republic's economic policies, highlighting issues such as high public debt, inadequate healthcare, and poor public services. It discusses the need to seek financial assistance from the International Monetary Fund and the burden placed on the middle class through fiscal adjustments. The text also references historical figures to emphasize its points.

The article analyzes the recent municipal elections in San Francisco de Macorís, highlighting the high voter abstention rate and questioning the attractiveness of the electoral candidates. It notes the PRM's victory despite low overall representativity and contrasts voting patterns between different social classes. The text also criticizes the FALPO for its limited electoral support despite its frequent protests. The author calls for a more refined and fair electoral system.

The text reflects on the personal and societal challenges posed by the pandemic, emphasizing self-discovery, learning opportunities, and adaptability. It highlights the importance of resilience and the role of academic institutions like Harvard in providing educational resources. The author stresses the need to focus on opportunities rather than lamenting losses and underscores the importance of reliable information and scientific efforts in combating the virus.

Julian Assange, the creator of Wikileaks, announced the upcoming release of 7,000 documents for download. Human rights organizations, including the Independent Human Rights Commission of Afghanistan and Amnesty International, criticized the publication for potentially exposing informants and soldiers, urging the removal of Afghan civilian names from the documents.
