NeuroAIDS refers to the neurological complications caused by HIV infection in the central and peripheral nervous systems. It can be caused primarily by the virus or secondarily by opportunistic infections. The virus does not directly infect neurons but damages them indirectly by infecting microglia, macrophages and astrocytes in the brain. This leads to clinical syndromes involving cognitive, motor and behavioral dysfunction. Common conditions include AIDS dementia, peripheral neuropathy, vacuolar myelopathy and primary CNS lymphoma. Diagnosis involves brain imaging, spinal fluid analysis and biopsy. Treatment focuses on ART, managing symptoms, and treating any underlying opportunistic infections.
Blitz was a Portuguese music magazine established in 1984 that aligned itself with emerging underground music scenes in opposition to the dominant record industry. The magazine's journalists saw themselves as "militant" in their promotion of new artists and tastes over mainstream commercial music. Through its writing, Blitz advocated an "ideology of difference" that valued creativity, innovation, and authenticity over imitation, conservatism, and music made only for mass popularity. This ideological stance positioned the magazine and its journalism against the mainstream Portuguese music industry and in support of independent labels, radio shows, retailers, and other media that shared its focus on new and different artists.

The revolutions in Tunisia and Egypt shared some similarities but ultimately led to different outcomes. Both overthrew long-standing authoritarian regimes in 2011 but Tunisia has transitioned more successfully to democracy while Egypt has reverted to authoritarianism. Key factors in Tunisia's success include stronger civil society, political compromise across ideological lines, and support from international actors for democratic reforms. Egypt has struggled due to political polarization, an influential military with authoritarian tendencies, and a lack of consensus on democratic values and institutions.

The CBC machine is a common diagnostic tool used by doctors to measure a patient's red blood cell count, white blood cell count and platelet count. The machine uses a small sample of the patient's blood, which is then placed into special tubes and analyzed. The results of the analysis are then displayed on a screen for the doctor to review. The CBC machine is an important tool for diagnosing various conditions, such as anemia, infection and leukemia. It can also help to monitor a patient's response to treatment.
Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
