Published: May 2024

Abstract

Coastal upwelling supplies nutrients supporting primary production, while also adding the toxic trace metal mercury (Hg), to the mixed layer of the ocean. This could be a concern for human and environmental health if it results in enhanced bioaccumulation of monomethylmercury (MMHg). Here we explore how upwelling influences the Hg cycling in the California Current Ecosystem (CCE) biome through particle scavenging and sea-air exchange. We collected suspended and sinking particle samples from an upwelled water parcel and a non-upwelled water parcel and observed higher total particulate Hg and sinking flux in the upwelling region compared to non-upwelling region. To further investigate the full dynamics of Hg cycling, we modeled Hg inventories and fluxes in the upper ocean under upwelling and non-upwelling scenarios. The model simulations confirmed and quantified that upwelling enhances sinking fluxes of Hg by 40% through elevated primary production. Such an enhanced sinking flux of Hg is biogeochemically important to understand in upwelling regions as it increases the delivery of Hg to the deep ocean where net conversion to MMHg may take place.

Published: May 2024

Background
The potential of artificial intelligence (AI) chatbots, particularly ChatGPT with GPT-4 (OpenAI), in assisting with medical diagnosis is an emerging research area. However, it is not yet clear how well AI chatbots can evaluate whether the final diagnosis is included in differential diagnosis lists.

Objective
This study aims to assess the capability of GPT-4 in identifying the final diagnosis from differential-diagnosis lists and to compare its performance with that of physicians for case report series.

Methods
We used a database of differential-diagnosis lists from case reports in the American Journal of Case Reports, corresponding to final diagnoses. These lists were generated by 3 AI systems: GPT-4, Google Bard (currently Google Gemini), and Large Language Models by Meta AI 2 (LLaMA2). The primary outcome was focused on whether GPT-4’s evaluations identified the final diagnosis within these lists. None of these AIs received additional medical training or reinforcement. For comparison, 2 independent physicians also evaluated the lists, with any inconsistencies resolved by another physician.

Results
The 3 AIs generated a total of 1176 differential diagnosis lists from 392 case descriptions. GPT-4’s evaluations concurred with those of the physicians in 966 out of 1176 lists (82.1%). The Cohen κ coefficient was 0.63 (95% CI 0.56-0.69), indicating a fair to good agreement between GPT-4 and the physicians’ evaluations.

Conclusions
GPT-4 demonstrated a fair to good agreement in identifying the final diagnosis from differential-diagnosis lists, comparable to physicians for case report series. Its ability to compare differential diagnosis lists with final diagnoses suggests its potential to aid clinical decision-making support through diagnostic feedback. While GPT-4 showed a fair to good agreement for evaluation, its application in real-world scenarios and further validation in diverse clinical environments are essential to fully understand its utility in the diagnostic process.

This theory suggests that the amount of effort individuals exert is directly influenced by their anticipation of particular outcomes and the degree to which those outcomes are personally appealing. Essentially, individuals adjust their behavior based on their assessment of the effort required to achieve specific outcomes and the value they attach to those outcomes. Within the realm of innovative entrepreneurship, organizational management faces a range of challenges. Among these, the rapidly evolving business environment stands out, necessitating constant adaptability and proactive planning. Additionally, attracting and maintaining talent is crucial, as the success of any enterprise heavily relies on its ability to recruit and retain key individuals. Furthermore, the establishment of an organizational culture has a profound impact on employee satisfaction, loyalty, and their capacity for innovation. Resource management also plays a pivotal role, particularly in the efficient allocation of funds, time, and technological resources. Lastly, competitive market forces and the need for strategic adjustments are realities that innovative entrepreneurial ventures must navigate, demanding continuous strategic realignment to maintain competitiveness. Against this backdrop of complexity and dynamism, the application of expectancy theory offers valuable insights for organizational management. By understanding and applying this theory, innovative entrepreneurial ventures can more effectively stimulate employee motivation, refine incentive systems, enhance goal management, and foster employee growth and engagement. To a certain extent, these functions can assist enterprises in overcoming various challenges in organizational management processes, thereby bolstering overall organizational performance.

Nori is a popular seaweed-based food made from red algae Porphyra. The demand for nori in Indonesia is increasing, but Indonesia does not have Porphyra as raw material and lacks knowledge to find alternatives. Pakcoy (Brassica rapa L.) is a nutritious vegetable that is rarely developed and has the potential to become an alternative raw material for nori. This research aims to develop nori made from pakcoy with various binders to approach commercial nori products. This study is expected to produce an alternative nori that is easily sourced and cultivated in Indonesia. The research used a Completely Randomized Design (CRD) method with 10 treatment levels, which are combinations of 3 types of binders (CMC, tapioca, and cornstarch) at 3 concentration levels (3%, 5%, and 7%). Pakcoy nori was made through the processes of washing, steaming, ginding, molding, and drying. The results of the study show that the addition of 3% CMC produces pakcoy nori with the most preferred color, aroma, flavor, and crispiness by the panelists. The use of CMC, tapioca, and cornstarch as binders can produce pakcoy nori with characteristics similar to commercial nori. This research indicates that pakcoy nori has the potential to be developed as an alternative raw material for nori using 3% CMC as a binder. Keywords: Binder, Brassica rapa L., CMC, Nori, Pakcoy, Porphyra

Currently, the public's tendency to consume traditional medicines is quite high, based on the existing potential, the medicinal product that can be widely developed is the turmeric plant. Turmeric stored in dry powder form has a lower curcumin content than fresh turmeric, namely containing 3-5% curcumin. Therefore, storing turmeric in powder form with a low water content is one way to maintain the quality of turmeric. This research was carried out with three treatments with three repetitions, including drying with a tool using solar energy, drying with a tool using electrical energy, drying with a tool using solar energy and electrical energy (hybrid), and drying using a winch (as a control). . Observations carried out to determine the physical properties of the turmeric flour produced were in the form of color measurements, bulk density measurements, air absorption measurements, stack angle measurements, and measurements of the degree of fineness of the material. Based on the results of the tests carried out, drying using solar and electric energy (hybrid) takes 8 hours, followed by testing using electric energy which takes 10 hours. The flouring process is carried out by blending dried turmeric for 5 minutes. The temperature and type of treatment carried out during the turmeric drying process did not have a significant effect on the turmeric flour produced. Keywords: drying, hybrid, flour, turmeric.
