Summary: Filtering and smoothing algorithms are essential tools for developing decision-making strategies and parameter identification techniques in various research areas. These algorithms are used to estimate the system state based on noisy measurements of the system output. In real-world systems, noisy measurements can lose significant information due to factors like sensor resolution and digitalization processes.

Summary: In this paper, a new two-dimensional gaussian hierarchical priority fuzzy system (TGHPFS) is proposed to handle interval-valued data. TGHPFS first performs hierarchical clustering of the average value of interval-valued data in each dimension to generate two-dimensional gaussian membership functions of two-level rules. The effectiveness of TGHPFS is validated using real-world datasets, and the proposed method is compared with other latest methods to show the superiority of TGHPFS.

Summary: This paper proposes a three-dimensional text image watermarking model based on multilayer overlapping of extracted two-dimensional information. The model embeds, extracts and overlaps multiple watermarks to generate a three-dimensional text watermarking. The influence of sequence order, positional distancing and color difference of the extracted two-dimensional information on displaying a three-dimensional text watermark image is discussed. The experimental results show that the proposed model exhibits good invisibility and robustness.

Summary: This paper investigates the performance of using the XOR rule to detect deterministic signals in bivariate Gaussian noise. The study finds that when the correlation coefficient approaches 1, the XOR rule with identical, alternating partitions of observations at the sensors (XORAP) is the optimal fusion rule. The Bayes error of XORAP decreases to zero at a slower rate compared to the exponential decrease of CLRT.

Summary: This study found a significant variation in DLS across the macula, especially around the fovea. The topographical change in cone separation is an important determinant of the variation in DLS. It is cautioned against extrapolating changes in DLS measurements to cone distribution due to the complex relationship between these variables.

Summary: This study found that protracted bacterial bronchitis is the most common cause of chronic cough in children referred to tertiary respiratory care, and is often misdiagnosed and undertreated prior to referral. There is a need to improve the diagnosis and management of PBB in primary care settings to potentially lead to earlier symptom resolution and prevent disease progression to bronchiectasis.

Summary: This study evaluated the effectiveness of continuous glucose monitoring in children with hypoglycemia, particularly in those with hyperinsulinism. Results showed that CGM had high accuracy in detecting severe hypoglycemia, but had a high number of false-positive readings at lower glucose levels. Parents reported less anxiety, better sleep, and a preference for using CGM for monitoring their at-risk children. Newer CGM systems with improved accuracy at lower glucose levels could further enhance monitoring in the future.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.
