Summary: In this study, the researchers identified a dwarf-red cotton mutant that is a gibberellin-sensitive mutant caused by a mutation in the GhDR gene. The mutation resulted in a frameshift and truncation of the GhDR protein, leading to altered subcellular localization. Transcriptome analysis revealed downregulation of key genes involved in gibberellin biosynthesis and upregulation of genes related to gibberellin degradation and anthocyanin biosynthesis pathway in the mutant. This study provides insights into the molecular basis of plant architecture and anthocyanin accumulation regulation in cotton.

Summary: In this paper, a novel three-parameters safety assessment methodology is proposed for accurately assessing the safety of a salvor-cable-wreck salvage system based on time-domain analysis. The motion responses in the lifting operation are simplified by integrating different motion modes and comparable cases to establish a uniform criterion. The water-soil-wreck interaction and salvor-cable interaction are solved using the 8-degree finite element method and lumped mass method, respectively. Several case studies under different sea states are simulated and quantitatively assessed using the proposed method, with a focus on safety, stability, and energy efficiency in salvage engineering. Assessment scores indicate that wave headings of 30 and 150 degrees are appropriate, while a wave direction of 180 degrees is the safest. Smaller wave periods are found to be ideal sea states for sunken vessel salvage. The shape of the sunken object has a relatively slight effect and mainly impacts the stability of the salvor barge. Under larger wave heights or longer wave periods, the maximum tension and extra energy consumption of the lifting cables tend to increase.

Summary: This study found that the coordination between Li+ and solvents determines the anodic stability of localized high-concentrated electrolytes (LHCEs) on high-voltage cathodes, which can be finely tuned by ambient diluents. Among the possible diluents, 2H,3H-decafluoropentane (HFC) was found to satisfy the principle of weak but sufficient interactions, which enhances Li+ coordination and offers excellent antioxidant chemistry. The study provides guiding principles for improving the cathodic and anodic stability of electrolytes, benefiting the development of LHCEs and inspiring next-generation lithium batteries formulation.

Summary: Phase change materials (PCM) are a promising option for thermal energy storage (TES), but their low thermal conductivity has hindered their use in high power density applications. The development of nano-enhanced PCM (NePCM) with highly thermally-conductive carbon-based nano-additives has made progress in enhancing the effective thermal conductivity. However, the presence of additives leads to a loss in energy density and an increase in viscosity, which can impact the overall performance of NePCM-based TES systems.

Summary: This study reports the uranium isotope ratios of twenty-nine geological reference materials, including various types of rocks and sediments. The measurements were done using a multi-collector inductively coupled plasma-mass spectrometer. The results show that most samples have U-234/238 values close to secular equilibrium, with minor fluctuations observed in Pleistocene speleothem samples. The U-238/235 values of igneous and metamorphic rocks are consistent with values found in the continental crust, while sedimentary rocks and sediments exhibit a wide range of values, indicating significant isotopic fractionation at low temperatures. The wider range of U-238/235 values reported in this study allows for inter-laboratory calibration of a broader range of geological and environmental samples.

Summary: Solid electrolyte interphase (SEI) is crucial for regulating interfacial ion transfer and safety in Lithium-ion batteries (LIBs). By using in situ heating X-ray photoelectron spectroscopy, the inherent thermal decomposition process of SEI is uncovered. Cryogenic transmission electron microscopy and gas chromatography are employed to investigate the composition, nanostructure, and released gases. The results show that even at room temperature, the organic components of SEI readily decompose, releasing flammable gases. The residual SEI after heat treatment is rich in inorganic components and provides a nanostructure model for a stable SEI with enhanced safety.

Summary: This paper proposes a modified predictive PID controller for dynamic positioning (DP) vessels, which combines PID and motion prediction techniques to improve the performance of DP systems. The controller compensates for slowly-varying forces and uses an appropriate autoregressive model for motion prediction. Comparisons and investigations are conducted on prediction length and environmental conditions. Simulation results show that the proposed controller is an attractive alternative to PID with acceleration feedback (AFB) when accurate acceleration measurement is not possible.

Summary: This study investigated the cycling stability of four pure and three mixture sugar alcohols and evaluated their phase change behaviors and stability. It was found that the latent heats of fusion/crystallization degrade upon consecutive melting-crystallization cycles, and a higher degree of superheat leads to a faster degradation.
