Summary: In this article, a highly sensitive dual-core microstructured fiber (DC-MSF) sensor is proposed, which achieves a high sensitivity by utilizing the adjustable dispersion characteristic of the DC-MSF and the zero value of group refractive index difference at the dispersion turning point (DTP) between y-polarization odd and even supermodes. The simulation results demonstrate that the sensor's sensitivity can reach up to 52,875 nm/RIU around an RI of 1.4, with operating bandwidths of sensitivity over 104 nm/RIU and 105 nm/RIU being 625 nm and 100 nm, respectively. Additionally, the DC-MSF can be employed as a temperature sensor by coating it with PDMS, offering a sensitivity of 23.12 nm/degrees C around 22 degrees C. The detectable RI and temperature ranges of the proposed DC-MSF sensor are 1.375-1.425 and -15 degrees C-95 degrees C.

Summary: This paper presents the fabrication and characterization of a temperature sensor based on periodically tapered optical fibers (PTOF). The study investigates the relation between the geometry of the sensors and sensing ability, emphasizing the importance of the number of tapered regions in PTOF for temperature response. Results show that sensors with a low number of tapered regions cannot be considered effective for temperature sensing, while sensors with more tapered regions demonstrate excellent sensitivity and linear fitting.

Summary: This paper presents and demonstrates an ultra-sensitive magnetic field sensor using a hybrid interferometer, which combines a Sagnac loop interferometer (SI) and a Fabry-Perot interferometer (FPI). By exploiting the difference in the free spectrum ranges of the two cavities, a Vernier effect is generated to amplify the sensitivity. Experimental results show that the hybrid sensor has a sensitivity of 811.53 pm/mT, which is about 32 times higher than that of a single individual FPI with a sensitivity of 25 pm/mT. The sensor can be applied in harsh environments such as mines, oil wells, and other fields.

Summary: This study theoretically analyzes and experimentally demonstrates the relationship between the temperature and strain sensitivities and the waist diameter of the tapered high birefringence fiber (THBF) in a Sagnac interferometer. Sagnac interference is sensitive to both temperature and strain when the waist diameter is large, but the sensitivities decrease as the waist diameter decreases. On the other hand, when the waist diameter of the THBF is sufficiently small, both Sagnac and modal interferences are simultaneously generated, with the former only sensitive to temperature and the latter sensitive to both temperature and strain. The proposed THBF Sagnac interferometer enables simultaneous measurement of temperature and strain variations, with the strain-insensitive characteristic of Sagnac interference facilitating the discrimination between temperature and strain variations.

Summary: An in-line digital optical sensor based on a tapered depressed-cladding single-mode fiber acting as a coaxial Mach-Zehnder interferometer is proposed. The sensor operates by computing the number of optical power transfer turning points (PTTP) from the transmission data of the component. Biconic tapers with high PTTP values, high spectral resolution, high extinction ratio, and low insertion loss were modeled, fabricated, and characterized. A proof of concept in-line digital strain sensor was fabricated and characterized, demonstrating a high digital resolution and quasi-symmetric response to stretch and compression.

Summary: A method of collaborative simulation is proposed to improve the computational efficiency of finite element numerical simulation of the train collision process. The study investigates the collision response of a train derailment hitting a platform with different curve radii. A collision damage index is proposed to assess the relative degree of damage at different curve radii. The results indicate a positive correlation between curve radius and collision damage index within a certain radius, and no collision occurs when the curve radius exceeds a certain value.

Summary: By modifying the entangled multi-degrees of freedom of transition-metal oxides, the symmetry-mismatch-driven interfacial phase transition from paramagnetic to ferromagnetic state is achieved in this work. The interfacial layer of CaRuO3, with approximately 3 unit cells in thickness, shows robust ferromagnetic order with a high Curie temperature of approximately 120 K and a large saturation magnetization of approximately 0.7 mu(B) per formula unit. Density functional theory calculations reveal that the reduced tilting/rotation of RuO6 octahedra favors an itinerant ferromagnetic ground state. This study demonstrates an effective approach to tune phases by coupled octahedral rotations and offers new opportunities for the exploration of emergent materials with desired functionalities.

Summary: The mechanisms of volatile anesthetics in the central nervous system are mainly through the modulation of synaptic neurotransmission. Isoflurane can selectively inhibit neurotransmission in GABAergic and glutamatergic synapses, which is related to the modulation of presynaptic voltage-dependent sodium channels. This study examined the effects of isoflurane on sodium currents in different types of neurons in the prefrontal cortex and found that isoflurane inhibited sodium currents more potently in pyramidal neurons than in PV+ neurons.

Summary: The construction of a slippery lubricant-infused porous surface (SLIPS) on transmission conductor via anodicoxidation was achieved, and the anti-icing mechanism of the slippery conductor was studied. Compared to the untreated conductor, the SLIPS-conductor reduces the icing weight by 77% in the glaze icing test and exhibits very low ice-adhesion strength. The excellent anti-icing performance of the slippery conductor is attributed to droplet impact dynamics, icing delay, and lubricant stability.

Summary: Transmission aluminum conductors in coastal areas are vulnerable to corrosion by salt and acidic solutions, leading to decreased mechanical strength and potential fractures. Traditional anti-corrosion methods are costly and inefficient, while superhydrophobic coatings based on the lotus effect lack durability. A novel approach of slippery liquid infused porous surface (SLIPS) was successfully applied to enhance corrosion resistance on 1060 pure aluminum, showing superior performance in simulated marine atmosphere. SLIPS exhibited minimal corrosion tendency, significantly reducing corrosion current and weight gain, and maintaining excellent corrosion resistance even after prolonged exposure to salt spray and simulated seawater immersion.

Summary: In this study, the thrust force during back-drilling in high-speed printed circuit boards is investigated. An ideal state mechanical model and an actual state mechanical model are proposed to predict the thrust force, taking into account the eccentricity effects. Experimental results show that the axial force first decreases and then increases as the eccentric distance increases during back-drilling. The effects of different microdrill parameters on the thrust force and stub length are also examined.
