The fundamental scientific and engineering knowledge concerning the solar power curve, which maps solar irradiance and other auxiliary meteorological variables to photovoltaic output power, has been gathered and put forward in the preceding tutorial review. Despite the many pages of that review, it was incomplete in the sense that it did not elaborate on the applications of this very important tool of solar energy meteorology. Indeed, solar power curves are ubiquitously needed in a broad spectrum of solar forecasting and solar resource assessment tasks. Hence, this tutorial review should continue from where it left off and present examples concerning the usage of solar power curves. In a nutshell, this tutorial review,together with the preceding one, should elucidate how surface shortwave radiation data, be they ground-based, satelliteretrieved, or model-output, are bridged to various power system operations via solar power curves.

Agricultural drought, a prolonged disaster with widespread impacts, exerts tremendous pressure on farm household activities,agricultural production, and economic development. The western region of Jilin Province, China, located in a semi-arid zone, where persistents drought exacerbates ecological fragility. With a larger proportion of its population living in rural areas, the life and production activities of households are particularly susceptible to drought-related challenges. This study focuses on the western part of Jilin Province, utilizing remote sensing data to calculate the temperature vegetation dryness index(TVDI) as a soil moisture monitoring indicator for drought assessment. The livelihood vulnerability index(LVI) and the improved LVI-Intergovernmental Panel on Climate Change(IPCC) index are employed to comprehensively assess the livelihood vulnerability of communes in the region and the impact of drought conditions on farmers' livelihood vulnerability. The results reveal a spatial trend of increasing drought severity from northeast to southwest, with temporally minor fluctuations observed in drought levels from 2005 to 2022. Livelihood vulnerability results indicate significant spatial and temporal variations, with education, health, food, and water playing key roles. Correlation analysis indicates a strong relationship between TVDI and LVI, highlighting the detrimental impact of drought on farmers' livelihoods. The study aims to provide a scientific foundation for managing livelihood vulnerability in the western part of Jilin Province and similar arid areas. Additionally, it seeks to offer strategic recommendations for policymakers to mitigate the adverse effects of drought, thereby reducing farmers' vulnerability and fostering sustainable socio-economic development.

Objective: To assess the effectiveness of the created program in enhancing the knowledge of emergency room(ER) nurses in the emergency management of cardiovascular diseases(CVD).Methods: This study used a quasi-experimental design with a one-group pretest-posttest research design to identify the knowledge and skills of emergency depar tment(ED) nurses in managing CVD. There were 16 par ticipants in this study. The mean, standard deviation(SD), and t-test were used to analyze the ***: Before the par ticipants undergo the program, they have a mean(SD) score of 17.63(5.19). After the completion of the didactic par t of the program, they garnered a mean(SD) score of 19.94(5.22). Moreover, after completion of the practicum par t of the program, the mean(SD) score was 21.94(5.04). Comparing the scores before the program and after finishing the didactic part of the program, the t-test scored(t(15) =-3.87, P = 0.001). Further, comparing the scores before the program and after finishing the didactic and practicum par ts of the program, the t-test scored(t(15) =-5.57, P = 0.001).Conclusions: Based on the study's results, the researchers conclude that the respondents had acceptable knowledge regarding the emergency management of CVD before the program. However, the Cardiac Enhancement Program for Emergency Cardiac Care boosted their knowledge. Also, the program is effective in enhancing the par ticipants' knowledge of the emergency management of CVD.

This paper examines an epidemic predator-prey model with prey dispersal and Holling type-II functional response. In this model, it is assumed that the predator population suffers a transmissible disease. By analyzing the corresponding characteristic equations, the local stability of each of feasible equilibria and the existence of Hopf bifurcations at the coexistence equilibrium is addressed. Using Lyapunov functionals and LaSalle's invariance principle, we obtained the sufficient conditions for the global stability of the trivial equilibrium, the predator-extinction equilibrium, the disease-free equilibrium and the coexistence equilibrium, respectively. The paper also includes numerical simulations to illustrate the analytical results.

Innovative anti-cancer therapies that activate the immune system show promise in combating cancers resistant to conventional treatments. Photodynamic therapy (PDT) is one such treatment, which not only directly eliminates tumor cells but also functions as an in situ tumor vaccine by enhancing tumor immunogenicity and triggering anti-tumor immune responses through immunogenic cell death (ICD). However, the effectiveness of PDT in enhancing immune responses is influenced by factors, such as photosensitizers and the tumor microenvironment, particularly hypoxia. Current clinically used PDT heavily relies on oxygen (O2) availability and can be limited by tumor hypoxia. Additionally, the tumor immunosuppressive microenvironment induced by hypoxia affects the anti-tumor immunity of tumor-infiltrating effector T cells. Meanwhile, the immunosuppressive myeloid-lineage cells are recruited to the hypoxic tumor tissue and exhibit higher immunosuppressive capabilities under hypoxia conditions. Consequently,numerous strategies have been developed to modulate tumor hypoxia or to create hypoxia-compatible PDT, aiming to reduce the effects of tumor hypoxia on PDT-driven immunotherapy. This review investigates these strategies, including approaches to alleviate, exploit, and disregard tumor hypoxia within the context of PDT/immunotherapy. It also emphasizes the role of advanced nanomedicine and its benefits in these strategies, while outlining current challenges and future prospects in the field.
