The impending rise of artificial intelligence(AI)-powered healthcare offers exciting hope for improved care and outcomes in children with serious illnesses.1 The historical precedent in healthcare,however,suggests that advancements in adult care do not necessarily result in proportional progress in *** disparity was first noted in the mid-20th century when tragedies that involved drugs with well-studied and known adult safety profiles,such as sulfonamide elixir and thalidomide,resulted in harm to children due to limited pediatric clinical trial inclusion.2 As a result,legislation in 1962 required drug companies to include package labels that restricted or dissuaded the use of medications in children that were not properly studied in this population.2 Subsequently,physicians became reluctant to prescribe many medications,and pharmaceutical companies had little incentive to enroll children in trials as an unfavorable result could negatively impact sales in the adult market,and a successful outcome would only marginally increase the market pool.3 This lack of access led *** Shirkey to describe children as"therapeutic orphans"in 1968.2 After more than half a century of legislation aimed at increasing pediatric representation in research and drug development(Figure 1),enrollment of children in clinical trials remains disproportionately low,4 with children included in as few as 12%of trials for diseases with a burden equal to,or greater in,the pediatric versus adult population.

Phytoremediation Strategies for Heavy Metal Contamination: A Review on Sustainable Approach for Environmental Restoration

引用

Journal of Environmental Protection 2024年第4期15卷 450-474页

作者： Mariam Salifu matthew Abu John Murtala Abubakar Ibukunoluwa Abimbola Bankole Nneka Damola Ajayi Olawumi Amusan Department of Chemistry and Biochemistry University of Mississippi Olemiss MS USA Department of Biochemistry Ahmadu Bello University Zaria Nigeria Department of Plant Pathology North Dakota State University Fargo ND USA Directorate of Research and Development Nigerian Institute of Leather and Science Technology (NILEST) Zaria Nigeria Department of Chemistry University of Akron Akron OH USA

Current globalization trends and important breakthroughs globally need a complete study of heavy metal contamination, its causes, its impacts on human and environmental health, and different remediation strategies. Heavy metal pollution is mostly produced by urbanization and industry, which threatens ecosystems and human health. Herein, we discuss a sustainable environmental restoration strategy employing phytoremediation for heavy metal pollution, the carcinogenic, mutagenic, and cytotoxic effects of heavy metals such as cadmium, copper, mercury, selenium, zinc, arsenic, chromium, lead, nickel, and silver, which may be fatal. Phytoremediation, which was prioritized, uses plants to remove, accumulate, and depollute pollutants. This eco-friendly method may safely collect, accumulate, and detoxify toxins using plants, making it popular. This study covers phytostabilization, phytodegradation, rhizodegradation, phytoextraction, phytovolatilization, and rhizofiltration. A phytoremediation process’s efficiency in varied environmental circumstances depends on these components’ complex interplay. This paper also introduces developing phytoremediation approaches including microbe-assisted, chemical-assisted, and organic or bio-char use. These advancements attempt to overcome conventional phytoremediation’s limitations, such as limited suitable plant species, location problems, and sluggish remediation. Current research includes machine learning techniques and computer modeling, biostimulation, genetic engineering, bioaugmentation, and hybrid remediation. These front-line solutions show that phytoremediation research is developing towards transdisciplinary efficiency enhancement. We acknowledge phytoremediation’s promise but also its drawbacks, such as site-specific variables, biomass buildup, and sluggish remediation, as well as ongoing research to address them. In conclusion, heavy metal pollution threatens the ecology and public health and must be reduced. Phytoremediation

Cooling High Power Dissipating Artificial Intelligence (AI) Chips Using Refrigerant

引用

Journal of Electronics Cooling and Thermal Control 2024年第2期13卷 35-49页

作者： Waheeb Mukatash Hussameddine Kabbani Jochem Marc Massalt matthew Moscoso Merari Mejia Robles Tyler Yang Charlie Nino Department of Mechanical Engineering San Jose State University San Jose USA

High power dissipating artificial intelligence (AI) chips require significant cooling to operate at maximum performance. Current trends regarding the integration of AI, as well as the power/cooling demands of high-performing server systems pose an immense thermal challenge for cooling. The use of refrigerants as a direct-to-chip cooling method is investigated as a potential cooling solution for cooling AI chips. Using a vapor compression refrigeration system (VCRS), the coolant temperature will be sub-ambient thereby increasing the total cooling capacity. Coupled with the implementation of a direct-to-chip boiler, using refrigerants to cool AI server systems can materialize as a potential solution for current AI server cooling demands. In this study, a comparison of 8 different refrigerants: R-134a, R-153a, R-717, R-508B, R-22, R-12, R-410a, and R-1234yf is analyzed for optimal performance. A control theoretical VCRS model is created to assess variable refrigerants under the same operational conditions. From this model, the coefficient of performance (COP), required mass flow rate of refrigerant, work required by the compressor, and overall heat transfer coefficient is determined for all 8 refrigerants. Lastly, a comprehensive analysis is provided to determine the most optimal refrigerants for cooling applications. R-717, commonly known as Ammonia, was found to have the highest COP value thus proving to be the optimal refrigerant for cooling AI chips and high-performing server applications.
