Summary: Variations in temperature can significantly impact the activity of microorganisms and the performance of wastewater treatment. Lower temperatures lead to decreased removal rates of ammonia, total inorganic nitrogen, and phosphorus. Gradually decreasing the temperature can help avoid inhibition of biological nutrient removal pathways, but it also affects the composition of the sludge, which warrants further long-term studies.

Summary: This study proposes the use of boron as an activator to promote partial nitrification and improve sludge properties. The results show that boron significantly increases the concentration of AI-2 in the reactor, and high concentrations of boron have better performance at two temperatures. Partial nitrification is achieved mainly through the accumulation of NO2--N facilitated by the increase in AI-2 concentration. Boron has no significant effect on AOB but inhibits NOB, especially at room temperature. EPS changes were also observed at the two temperatures. This study provides a new strategy for the rapid and stable initiation of partial nitrification.

Summary: The ability to vary the temperature of an electrochemical cell can control reaction rates and pathways, and drive processes that are inaccessible at ambient temperature. By controlling the temperature, the reaction rate and dissolution potential of the electrochemical Ni etching process can be changed. In situ measurements suggest that the destabilization of the native nickel oxide layer is a slow step in the electrochemical Ni dissolution process.

Summary: Laser-driven recollision physics is typically limited to high field intensities, but using extreme ultraviolet and near-infrared pulses allows for studying recollision dynamics at a broad range of intensities. Transient absorption spectroscopy and time-dependent dipole moment reconstruction are used to analyze recollision dynamics. The comparison of linear and circular near-infrared polarization reveals the existence of recolliding periodic orbits.

Summary: This study investigated the cell growth, lipid production, and Cr6+ removal of Parachlorella kessleri R-3 at pH 3.5 and 15 degrees C. It was found that low concentration of Cr6+ promoted algal growth, while high concentrations inhibited growth. The highest biomass concentration (2.40 g/L) and lipid productivity (131.79 mg/L d-1) were achieved at 2 mg/L Cr6+, while the highest lipid content (61.03%) was achieved at 5 mg/L Cr6+. The maximum Cr6+ removal efficiency of 91% was obtained at 0.5 mg/L Cr6+. Fatty acid composition analysis showed a high content of C16-18 in strain R-3 (74.88-89.21%). This study provides new insights into the treatment of heavy metals and lipid production in cold regions.

Summary: A partial-nitrification/anammox and endogenous partial-denitrification/anammox (PN/A-EPD/A) process was developed in a sequential batch biofilm reactor (SBBR) to achieve advanced nitrogen removal from low-carbon wastewater. The effluent total nitrogen (TN) reached 3.29 mg/L when the influent COD/TN and the TN were 2.86 and 59.59 mg/L, respectively. The stable PN/A-EPD/A process was achieved through four strategies, including treating the inoculated sludge with free nitrous acid, inoculating anammox biofilm, discharging excess activated sludge and residual ammonium at the end of oxic stage. The 16S rRNA high-throughput sequencing results showed the coexistence of anammox bacteria, ammonia oxidizing bacteria, nitrite oxidizing bacteria, denitrifying glycogen accumulating organisms (DGAOs) and denitrifying phosphorus accumulating organisms (DPAOs) in the biofilms, with higher abundance of anammox bacteria in the inner layer and higher abundance of DGAOs and DPAOs in the outer layer.

Summary: This paper studies the problem of guaranteed cost control and anti-windup design for a class of switched systems with actuator saturation. The switching strategy and anti-windup compensator are designed to ensure the stability of the closed-loop system and minimize the cost function. Sufficient conditions for the existence of an anti-windup compensator of guaranteed cost are presented using the multiple Lyapunov functions method. Based on these conditions, the minimum upper bound of the cost function is determined by solving an optimization problem under the constraint of linear matrix inequality (LMI). A numerical example is provided to demonstrate the effectiveness of the proposed method.

Summary: A robust Bayesian design is proposed for monitoring a time to event endpoint in a single-arm phase II trial. Simulation results show that the piecewise exponential design has better performance than the exponential inverse gamma model based design, with higher probabilities of correctly stopping the trial early and shorter and less variable trial duration. Compared to the Weibull model based design, the piecewise exponential design does a better job of maintaining small incorrect stopping probabilities when the true median survival time is desirably large.

Summary: Conjugated polymers (CPs) have received increasing attention in photocatalysis due to their stability and molecular tunability. In this study, a new efficient cyano (CN) engineering approach was proposed to enhance the photocatalytic performance of CPs. Three CP-based photocatalysts with different CN contents were synthesized to investigate the relationship between CN functionalization and photocatalytic activity. Experimental and theoretical studies revealed that CN functionalization strengthened the donor-acceptor (D-A) interaction, enhanced light absorption, charge separation/transfer efficiency, hydrophilicity of CPs, and facilitated the output of photoinduced electrons from CPs to Pt cocatalyst.

Summary: The 3D flow filling process of LOX dome in a liquid oxygen/methane rocket engine was studied, and the volume, flow field pressure, and velocity distributions of liquid oxygen at different times were determined. The flow property of propellant and the injection characteristic time of liquid oxygen were obtained. The results revealed that when the LOX dome was not filled, the flow state of LOX was disorderly and it flowed around the annular wall in the middle dome. However, after the LOX filling was completed, the liquid oxygen flow became stable and the overall velocity distribution became more uniform. There were also varying injection delays in different areas, leading to the inhomogeneity of injection characteristic time and flow rate in the thrust chamber.
