Hearing loss is a critical global health issue that affects over 1.5 billion people worldwide, with a disproportionate burden in Low- and Middle-Income Countries (LMICs). These regions face significant challenges, including limited access to audiological services, a shortage of healthcare professionals, and a lack of affordable hearing solutions. These barriers lead to delayed diagnoses, inadequate management, and a significant negative impact on individuals' quality of life, education, and employment opportunities. The advent of Artificial Int...elligence (AI) and advanced technologies offers innovative pathways to address these longstanding challenges. This review introduces the AI-driven smart Auditory Health Systems (SAHS) concept. This holistic approach integrates AI, wearable devices, Internet of Things (IoT) technology, and big data analytics to enhance the prevention, diagnosis, and management of auditory disorders. SAHS systems can provide real-time monitoring, early detection of hearing loss, and personalized care solutions tailored to individual and population needs. These systems offer community-level interventions, including noise pollution monitoring and data-driven public health strategies. Focusing on the LMIC context, this review explores the technological framework, applications, ethical considerations, and logistical challenges of implementing SAHS. By leveraging these advanced technologies, SAHS has the potential to bridge gaps in healthcare access, improve health outcomes, and transform auditory healthcare delivery in resource-constrained settings. This review underscores the importance of collaborative efforts in research, policy development, and capacity building to ensure equitable adoption of SAHS, thereby addressing hearing health disparities globally.Read more

In recent years, SpaceX posted several glossy websites claiming they would implement a very ambitious human mission to Mars as early as 2028. This is an innovative mission concept using several 100 MT “Starships” to transport multiple 100 MT payloads to the Mars surface and return the crew directly to Earth without a rendezvous. Although many details are not available, it has been revealed that it would utilize 1,200 MT of CH4 and O2 propellants in LEO, and an additional 1,200 MT of ISRU-generated CH4 + O2 propellants on Mars for th...e return flight. The landed crew would number 12. It would land about six Starships on Mars, requiring about 72 heavy lift launches to fuel the vehicles in LEO. The challenges include landing a 200 MT loaded Starship on Mars, a massive water-based ISRU system to provide propellants on Mars, and launching many vehicles within a launch window. While reducing mass was a central theme years ago, launch costs have decreased sharply, and reducing mass is no longer a priority. The SpaceX mission maximizes mass to reduce risk and maximize accomplishments. In this study, an attempt was made to determine whether mass allocations for such a mission are feasible. The results suggest that it might be theoretically possible for SpaceX to carry out a variety of such missions. However, the SpaceX mission faces herculean challenges and probably is at least three decades away. Nevertheless, the general approach is probably more relevant today than the NASA architectures generated so far. The claim of landing humans on Mars in 2028 seems overly ambitious.Read more

The Lama language, spoken in Togo, West Africa, belongs to the Gur language family. Linguistic studies on Lama‘s tonal system, particularly within the generative grammar framework, remain limited. This study presents a detailed analysis of the tonal rules in Lama, focusing specifically on noun morphology. A comparative analysis of four noun categories reveals: (a) the categories exhibit three surface tone patterns (high-level, low-level, and falling) in isolation; (b) within phrases, the Low Tone Deletion Rule polarises the categories to ...two tones, retaining only high-level and low-level tones, as falling tones are blocked in this context; (c) tone alternation is governed by the High Tone Spread Rule; (d) while the underlying tones correspond to surface tones in the first three categories, the fourth category’s underlying rising LH sequence never surfaces and is simplified to a low-level tone via the Contour Tone Simplification Rule; and (e) the phenomenon of downstep arises from the interaction of the High Tone Spread, Low Tone Deletion, and Contour Tone Simplification rules.Read more
