The recent multi-sensor Generalized Labeled Multi-Bernoulli (GLMB) is an efficient analytic implementation to the multi-sensor multi-object state estimation problem. The multi-sensor multi-object posterior is recursively propagated using the multi-sensor multi-object filtering density, by updating it with multi-sensor measurements at each time step. The measurement update step requires solving a series of NP-hard multi-dimensional assignment problems. In this paper, we introduce a faster implementation of this algorithm by an intuitive approximation, and combine that with the Gibbs sampler based truncation approach to produce an efficient multi-sensor multi-object estimation solution suitable for practical applications.

The article presents a unique design for a hollow-core anti-resonant fiber, which utilizes a single-layer semi-circular antiresonant unit positioned around the central core. The simulation analysis reveals this design can achieve transmission over a wide bandwidth of 500-1300nm, while exhibiting relatively low losses at wavelengths near 700-800nm and 900-1100nm. The anti-resonant fiber with this structure boasts strong wavelength limitation capability for light transmission, along with high transmission stability in a low-loss mode. Based on the simulation analysis results of the changes in loss characteristics, the hollow core anti-resonant fiber we designed has a mode field diameter of approximately 30 microns, and the wall thickness of the core anti-resonant structure is approximately 0.4 microns. By optimizing the process, such as through preform shaping and wire tension adjustment, a 5km long span with high uniformity was achieved for the hollow core anti-resonant fiber, and corresponding tests were carried out. The test results indicate that the total loss value of the hollow anti-resonant fiber, prepared under optimized process conditions, can be managed at a reduced level, with an attenuation of less than 0.1dB/m at 1064nm. Due to the outstanding pure single mode characteristics of optical fibers, there is no obvious mode coupling between the optical signal and the quartz cladding, neither the inner quartz wall in the transmission channel. In devices utilizing fiber enhanced Raman spectroscopy (FERS), this particular fiber can achieve highly sensitive sensing and precise analysis of Raman spectroscopy. Due to its low attenuation characteristics, the system achieves excellent sensing performance in fiber-enhanced Raman spectroscopy systems, enabling precise detection of a 450ppm CO2 concentration. Based on simulation analysis and testing, this article confirms the benefits of this novel fiber in fiber-enhanced Raman spectroscopy systems, presenting a fresh op

This work examines the diverse properties and environmental applications of two-dimensional black phosphorus (BP), a promising nanomaterial noted for its remarkable mechanical, thermal, electrical, and optical characteristics. We elucidate multiple preparation methods, encompassing both top-down and bottom-up approaches, emphasizing the importance of synthesis techniques in augmenting BP's functionality. The distinctive puckered crystal architecture of BP enables the formation of heterostructures that display unique properties, essential for applications in water treatment and sensing. Our research also highlights the significant anisotropic optical, mechanical, and electrical characteristics of BP, rendering it a compelling candidate for electrochemical energy storage and water purification applications. For the water treatment applications, we examine the effectiveness of BP in membrane-based processes, where its integration into membranes improves pollutant rejection and antibacterial characteristics. Furthermore, we introduce advanced point-of-use disinfection systems employing BP nanosheets, showcasing their efficacy in eradicating microbial contaminants. Other applications include BP's utilization in sensing technologies, specifically its capacity to identify hazardous gases and organic pollutants via improved adsorption mechanisms. © 2024 The Authors.

Compared with those traditional initiating devices of anti-scalding systems, ionic thermoelectric sensors with energy-autonomous performance show higher reliability. However, the current ionic thermoelectric materials (i-TEs) suffer from complex nano-/micro-channel design, high production costs, environmentally unfriendly, weak mechanical properties, as well as the low moving speed of ions. Herein, the functional leather collagen fibers-bearing natural channels are employed as the polymer matrixes, while the trisodium citrate (SC) organic acid salt exhibits the function of cationic moving self-enhancement as the primary mobile ions for signaling. Including numerous and suitable nano-/micro-channels together with fast-moving cations, the leather-based i-TEs (LITE), LITE-SC0.75 M, possess excellent thermoelectric properties, achieving a Seebeck coefficient of 6.23 mV/K, a figure of merit of 0.084, and an energy conversion efficiency of 2.12%. Combined with its excellent thermal stability, mechanical performance, flexibility, durability, low cost, and outstanding capabilities for low-grade heat harvesting and thermal sensing, the LITE-SC0.75 M detector bearing long service life would show great promise in automatic anti-scalding alarm suitable for multiple scenarios and extreme environments. Therefore, the present work aims to design an efficient, robust, and energy-autonomous leather collagen fibers-based thermoelectric detector to address the limitation of current anti-scalding alarm technology as well as drive advancements in the nano-energy and its effective conversion *** AbstractThe robust leather collagen fibers-based ionic thermoelectric (i-TEs) detectors with numerous nano-/micro-channels and fast-moving cations are successfully constructed, which demonstrate great potential for automatic anti-scalding applications in various scenarios and extreme environments

In recent years, the automation of dairy management using artificial intelligence has been sought after, with mastitis detection being one such application. Mastitis is an inflammatory response that occurs in dairy cows, leading to economic losses such as decreased milk production. Therefore, early detection is desirable. Currently, raw milk analysis devices using lactate dehydrogenase (LDH), a biomarker, are widely used for early mastitis detection. However, the use of sensor systems often results in false positives. It is common practice to refer to detection results from the past few days for the final infection judgment, which relies on the farmer’s experience, leaving room for improvement. This study aims to combine raw milk analysis devices with machine learning techniques to detect mastitis more accurately without relying on the farmer’s experience. We constructed three machine learning detection models, achieving a maximum recall of 0.89, precision of 0.81. Furthermore, the infection prediction approach proposed in this study is widely applicable and can achieve more advanced predictions when combined with related research. © 2024 IEEE.
