This study endeavors to develop an improved set of basis functions for nuclear shell-model calculations. The shell model, a well-established approach to understanding nuclear structure,typically employs the harmonic oscillator potential within the mean-field approximation. Given the extensive validation and consistency of harmonic oscillator results with experimental data,we propose a modification by incorporating a centrifugal term that converges toward the Davidson potential. This potential has been extensively studied, and we aim to extract relevant experimental data for the simplest cases in the shell model, namely one-particle and one-hole nuclei. A comprehensive comparison between the Davidson-based results and the harmonic oscillator calculations is presented to demonstrate the effectiveness of the new basis functions.

The increasing drive towards eco-friendly environment motivates the generation of energy from renewable energy sources (RESs). The rising share of RESs in power generation poses potential challenges, including uncertainties in generation output, frequency fluctuations, and insufficient voltage regulation capabilities. As a solution to these challenges, energy storage systems (ESSs) play a crucial role in storing and releasing power as needed. Battery energy storage systems (BESSs) provide significant potential to maximize the energy efficiency of a distribution network and the benefits of different stakeholders. This can be achieved through optimizing placement, sizing, charge/discharge scheduling, and control, all of which contribute to enhancing the overall performance of the network. In this paper, we provide a comprehensive overview of BESS operation, optimization, and modeling in different applications, and how mathematical and artificial intelligence (AI)-based optimization techniques contribute to BESS charging and discharging scheduling. We also discuss some potential future opportunities and challenges of the BESS operation, AI in BESSs, and how emerging technologies, such as internet of things, AI, and big data impact the development of BESSs.

Data obtained from the calcareous nannofossils, distributed in the upper part of the Pabdeh Formation(Priabonian–Rupelian) and the lower part of the Asmari Formation(Chattian) in the Bid-Zard section, were used to investigate the Eocene to Oligocene palaeoenvironmental conditions in the southwest of Izeh, southwestern Iran(eastern Tethys). The upper part of the Pabdeh Formation was composed of shale, thin-bedded pelagic limestone and dolostone, which is disconformably overlain by the Asmari Formation. For the first time, 29 species of calcareous nannofossils belonging to 13 genera were identified in the studied section. The calcareous nannofossils in the upper part of the Pabdeh Formation indicate the Isthmolithus recurvus Zone/Sphenolithus pseudoradians Zone(combined zone), Ericsonia subdisticha Zone, Helicosphaera reticulata Zone and Sphenolithus praedistentus Zone,from the Priabonian to the Rupelian. The Sphenolithus ciperoensis Zone of the Chattian was identified in the lower part of the Asmari Formation. Calcareous nannofossil stratigraphy across the upper Eocene–Oligocene interval also reveals a disconformity at the Rupelian/Chattian transition due to a bio-event. Shallowing of the basin and environmental changes in this part of the Tethyan domain could have led to the lithostratigraphic and biostratigraphic changes. In fact, during the late Eocene to late Oligocene, marine phytoplankton was sensitive to climate changes such as decreasing temperature, as well as possibly to a nutrient increase and changes in basin depth.

Objective: To assess the effects of Falcaria vulgaris(F. vulgaris) as an antioxidant on damage to kidney of diabetic rats. Methods: Diabetic rats were established via streptozotocin(60 mg/kg). Various doses of F. vulgaris extracts(50, 100 and 150 mg/kg) and streptozotocin + F. vulgaris extracts were administered via intraperitoneal(i.p) injection to 48 rats(n=8 per group) for 28 d. Subsequently, ferric ion reducing antioxidant power(FRAP) of renal tissue, thiobarbituric acid reactive species, blood glucose concentrations, insulin, nitrite oxide, the weight of animals, glomeruli characteristics and kidney function were evaluated. Results: Compared with the control rats, diabetic rats showed significant increase in malondialdehyde, blood urea nitrogen, creatinine, blood glucose, nitrite oxide contents in renal tissues, and glomerular diameter. Furthermore, tissue FRAP level, body weight, number of glomeruli and plasma insulin were markedly reduced in diabetic rats when compared with the control group(P < 0.05). However, in all F. vulgaris and F. vulgaris + streptozotocin groups, malondialdehyde level, blood urea nitrogen, creatinine, glomerular diameter, nitrite oxide, and glucose levels were decreased significantly; meanwhile, tissue FRAP level, body weight, glomeruli number and insulin serum level were increased, compared to the control diabetic group(P < 0.05). Conclusions: F. vulgaris extract alleviates renal damage in diabetic rats.
