Summary: In this article, a lift-off point of intersection (LOI) feature is discovered for the first time from the raw signals of ACFM for the elimination of spurious signals caused by lift-off variations. A theoretical model is established to analyze the effect of lift-off variations on the characteristic signals of ACFM. Validation experiments show that the novel Bx signal plotted by LOI amplitude has no spurious signals caused by lift-off variations and can accurately evaluate the crack depth as with traditional Bx signals.

Summary: This paper investigates the effects of alternating current (AC) field on the rheological properties of fresh cement-based pastes. The results show that the AC field significantly increases the yield stress, plastic viscosity, and thixotropic properties of the paste. The rheological parameters change more significantly with an increase in AC voltage. The study also finds that the changes in paste temperature are the main reason for the rheology change. This research provides important technical support for preventing segregation and improving the stability of fresh concrete after casting.

Summary: This article identifies and obtains electromagnetic interference (EMI) signals under two types of ultraserious current conditions. It introduces the finite integral time-domain (FITD) method into the primary-secondary fusion switch to obtain the radiated magnetic fields of the two types of transient currents. The radiated magnetic field near the secondary equipment is then calculated and analyzed. The research results are valuable for understanding and formulating EMC standards for MV switches and highlight the potential malfunctioning of sensitive equipment caused by the obtained radiated magnetic field.

Summary: Compared to other curing methods, alternating current curing (ACC) in cement-based materials has the advantages of easy operation and effective quality control. The percolation threshold of carbon black (CB) in fresh paste is determined to be 1 vol% by experiments and simulations, to lower resistivity and improve ACC efficiency. By using fixed voltage and frequency, the effect of ACC on the hydration, compressive strength, and pore structure of CB-cement conductive composite (CBCC) is studied. The results show that ACC greatly shortens setting time and increases compressive strength by improving hydration temperature, resistivity, pore structure, and capillary water absorption.

Summary: This study experimentally investigated the effects of a low-frequency alternating-current electric field on premixed combustion. The results showed that the electric field could promote both laminar and turbulent combustion, increasing the flame propagation velocity. However, the effect gradually weakened as the frequency of the electric field increased. The impact of the electric field strength on the pressure of turbulent flame was significant only when it reached a certain level.

Summary: This study proposes an electromagnetic inspection method for monitoring the thickness of nickel plating on rolling rolls in paper mills by utilizing the difference in electromagnetic properties between nickel and S25C steel. However, the detection signal is influenced by the changing distance (lift-off: L-o) between the electromagnetic sensor and the nickel plating. By measuring the magnetic field in two directions of the electromagnetic sensor, it is demonstrated that both the thickness of nickel plating and L-o can be evaluated.

Summary: We construct a holographic effective superconducting theory by considering a special gauge-axion coupling. In the normal state, a peak emerges in the mid-IR in the AC conductivity for certain strength of broken translations and the gauge-axion coupling, attributed to the emergence of pseudo-Goldstone mode. In the superconducting phase, the gauge-axion coupling leads to a more evident gap in low-frequency conductivity.

Summary: This study investigates the impact of alternating electric field (AEF)-assisted freezing-thawing-aging sequence on muscle microstructure and myofibrillar protein characteristics. Three treatments were applied to the longissimus dorsi (LD) muscle: only aging, freezing-thawing-aging sequence, and AEF-assisted freezing-thawing-aging sequence. The results showed that the group with only aging exhibited fewer cracks between muscle fibers and maintained the integrity of the Z-line compared to the other two groups. Additionally, the AEF treatment effectively reduced myofibrillar fragmentation, protein aggregation, and oxidation.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
