Summary: Researchers have proposed a new method for measuring time series irreversibility, which supplements existing tests based on permutation patterns by considering information about the evolution of signal amplitude over time. Experimental results with synthetic time series show that the results obtained with this method complement those obtained with permutation patterns alone, suggesting that different irreversibility metrics are applicable in different situations.

Summary: A rocket delivery system based on metal ion/enzyme responses has been established for the treatment of Alzheimer's disease (AD). The system can target and penetrate the blood-brain barrier, effectively reducing the levels of amyloid-beta plaques, phosphorylated tau, and oxidative stress, thereby improving AD symptoms.

Summary: Characterizing and controlling entanglement in quantum materials is crucial for the development of next-generation quantum technologies. In this study, the authors propose a systematic approach to quantify the time-dependent quantum Fisher information and entanglement depth of transient states of quantum materials using time-resolved resonant inelastic x-ray scattering. This work sets the stage for experimentally witnessing and controlling entanglement in light-driven quantum materials via ultrafast spectroscopic measurements.

Summary: A thermodynamically consistent model for discrete time crystals is introduced and analyzed using stochastic thermodynamics. The study reveals that coherent oscillations can emerge even in the absence of synchronization. The mean-field model displays subharmonic synchronization while the 2D model shows a time-crystalline phase.

Summary: The interaction between gas flow and liquid flow is important in both fundamental science and practical applications. A needleless Karman vortex solution blow spinning system has been developed that can produce high-quality nanofibers with large throughput. The system can be scaled up for mass production without compromising quality.

Summary: Ethane steam cracking to ethylene plants generate organic sewage with oil and suspended solids, causing heat exchanger blockage and steam regeneration difficulties. This study proposes a cooperative process using medium particles extraction (MPE) and combined fibrous coalescence (CFC) technology to remove oil and turbidity in process water. Pilot tests showed that the process reduced the average oil content from 606 to 18.4 mg/L and turbidity from 1213 to 7.9 NTU, with separation efficiencies of 96.96% and 99.35%, respectively. This approach provides better separation effect, operational flexibility, and environmental friendliness compared to current treatments.

Summary: The study uses finite-time thermodynamics to analyze the energy consumption lower bound in mechanical separation processes, showing that the consumption does not approach zero when one component's molar fraction tends to unity. It also examines multistage separation processes with recycles, particularly isotope separation systems, deriving relations between fluxes, mass transfer surfaces, and stage number. Additionally, the study determines the optimality condition for the sequence of separations in mechanical separation systems for multicomponent mixtures.

Summary: In practical aerodynamic problems, curved shock/boundary layer interaction (CSBLI) is more common than the canonical shock/boundary layer interaction (SBLI). This study introduces streamwise and spanwise curvatures to establish an analytical model for the interaction length scale of CSBLI based on conservation of mass. The validity and universality of the model are verified, revealing the impact of shock curvatures on the interaction.

Summary: Future biogas plants need proactive feeding management to produce biogas according to demand, with simulation of biogas production depending on substrate supply. A research investigation presents a simulation model based on time series analysis principle, using historical data of biogas formation and solid substrate supply without differentiation of individual substrates. The model demonstrates self-learning capabilities and automatic adaptability to various applications, regardless of substrate composition.

Summary: Polylactide (PLA) nanofiber membranes with enhanced hydrophilic properties were successfully prepared by adding cellulose diacetate (CDA) through electrospinning. The addition of CDA improved the hygroscopicity and water flux of the PLA nanofiber membranes. The PLA/CDA nanofiber membranes exhibited excellent hydrophilic properties and biodegradability, making them a promising environmentally friendly oil-water separation material.

Summary: This paper proposes a new two-dimensional multi-scale time-frequency reverse dispersion entropy (CMTFRDE2D) algorithm to analyze the complexity characteristics of vibration signals, improving the instability of MDE1D. By introducing a composite coarse-grained process, the CMTFRDE2D algorithm can preserve more useful information. Experimental results show that this method can successfully extract fault information from rolling bearing vibration signals in the time-frequency domain and accurately identify different fault locations and severities of rolling bearings.

Summary: In this study, we investigate the problem of minimizing the entropy production for a physical process described by Markov jump dynamics. We find that, without any additional constraints, a given time-evolution can be realized with arbitrarily small entropy production at the expense of diverging activity. However, when the activity is fixed, the dynamics that minimizes the entropy production is driven by conservative forces. Moreover, we express the value of the minimum entropy production in terms of the graph-distance based Wasserstein distance between the initial and final configuration, which introduces a new type of speed limit relating dissipation, the average number of transitions, and the Wasserstein distance. We also demonstrate our findings using simple state networks, a time-dependent pump, and spin flips in the Ising model.

Summary: The science on public mask wearing to prevent COVID-19 transmission is rapidly evolving. Evidence suggests that wearing masks reduces the transmission of infected respiratory particles, especially when compliance is high. It is recommended to promote widespread use of face masks in public settings, along with existing hygiene practices, social distancing, and contact tracing strategies.

Summary: The text discusses the rapid spread of COVID-19 into a global pandemic within a short period of time, highlighting the challenges posed by transmission from pre-symptomatic and asymptomatic carriers. By constructing an epidemiological model focused on transmission around symptom onset, specific transmission control measures are explored to reduce the basic reproduction number R-0 and control virus spread. This modeling approach allows comparison of the pandemic's behavior in different regions and identifies both common and unique features in its development.
