Summary: This paper presents a novel analytical method to optimally size energy storage in microgrid systems. The method is fast and efficient, accurately determines the optimal size, and accommodates non-linear models. It constructs a temporal storage profile based on the charging and discharging of storage in response to renewable generation and load demand. The storage is sized to maximize utilization and eliminate waste, leading to increased renewable consumption and decreased load shedding. The method is demonstrated through solar-battery case studies, showing the avoidance of over-sizing or under-sizing and the diminishing returns of increasing storage size.

Summary: This study proposes a new integrated system combining PV cells with a thermally-regenerative ammonia battery (TRAB) to convert full spectrum solar energy into electricity. The results showed that the integrated system achieved a higher solar electrical efficiency compared to a single PV system, whether the electricity is transmitted directly to users or stored in a battery. When the electricity generated was prioritized for delivery to users and the excess electricity stored in the battery, the proposed system met users' electricity demand in real time with an overall solar electrical efficiency of approximately 22.07%.

Summary: This study found that levels of chemerin and inflammatory cytokines were higher in the gingival crevicular fluid and serum of chronic periodontitis (CP) patients, and were positively correlated with each other. Periodontal ligament stem cells (PDLSCs) isolated from CP patients had higher expressions of chemerin and these cytokines compared to healthy individuals. Furthermore, chemerin dose-dependently increased inflammatory responses and inhibited osteogenic differentiation of PDLSCs.

Summary: This article proposes an efficient polar coded selective decode-and-forward (SDF) cooperation method to address the error propagation issue in satellite IoT devices with terrain shielding. The method utilizes channel state information (CSI) to derive a new decision threshold based on the channel gain ratio of the optimal relay-destination link (R-D). Simulation results show that the proposed scheme achieves about 0.9 dB and 0.5 dB gains at a bit error rate (BER) of 10-4, respectively, compared to non-cooperation and existing polar coded cooperation channels.

Summary: In this study, the influence of ammonia on different methanogenic pathways was evaluated by culturing Methanosarcina barkeri with acetate, H2/CO2, and methanol. Aceticlastic methanogenesis was more sensitive to increased ammonia concentrations than hydrogenotrophic and methylotrophic methanogenesis. The results reveal the varying ammonia tolerances of M. barkeri under different methanogenic pathways, providing insights into the role of the thermodynamic potential of methanogenesis in ammonia stress tolerance and shedding light on the mechanism of ammonia inhibition on anaerobic digestion.
