Published: August 2023

The youth represent a significant source of hope for a developing country such as the Philippines. Adolescents show a lack of interest in pursuing education leading to high dropout rates. Many researchers have conducted several studies to determine why students stop schooling. This study aimed to investigate the dropout determinants that influence out-of-school youth in Iligan City and Lanao Del Norte. Purposive sampling was used. Two hundred (200) out-of-school youth from Iligan City and Lanao Del Norte were the participants of this study. The researchers used a Likert scale survey questionnaire to collect the data. In addition, the researcher used descriptive analysis to calculate the median and frequency. The results found that academic experience especially boredom in the classroom was the leading dropout determinant influencing out-of-school youth. The other factor was family financial support. The study recommends that the government, non-government organizations and all stakeholders not only focus on providing financial assistance to students but also consider the students' learning experience inside the classroom. Academic boredom is a serious issue that requires immediate solutions.

Variable Step‐Size LMS Algorithm Based on Variational Versoria Function and Variational Gaussian Function
Authors: Zhao Baoshui , Xiao Yancai , Shen Haikuo , Zhi Shaodan 
Published: January 2025

ABSTRACTAiming at the noise interference problem in wing fatigue tests, this paper improves the traditional LMS algorithm using the variational Versoria function and the variational Gaussian function. Additionally, this paper proposes a variable step‐size LMS (VSS‐LMS) filtering algorithm based on the composite function (CVSS‐LMS). The composite function combines the variational Versoria function and the variational Gaussian function to describe the nonlinear relationship between the iteration step size and the error. To adapt to environments with different signal‐to‐noise ratios, the algorithm replaces the fixed parameters with a combination of current and previous errors, thus enabling adaptive adjustment of the parameters. Moreover, a step‐size dynamic constraint rule is proposed to further improve the stability of the algorithm. The algorithm is normalized using a combination of the cumulative sum of error squares, the mean square error (MSE), and the power of the input signal, which reduces the sensitivity to the input signal amplitude. The above parts finally constitute the adaptive CVSS‐LMS (ACVSS‐LMS) filtering algorithm. The convergence of the ACVSS‐LMS algorithm is verified through theoretical derivation. The ACVSS‐LMS algorithm is experimentally analyzed by using the simulation data generated by MATLAB and the actual data collected from the wing fatigue test, and the results show that the ACVSS‐LMS algorithm proposed in this paper has a faster convergence speed and lower steady‐state error compared to other algorithms.
MTN‐Based Adaptive Finite‐Time Tracking Control for Switched Non‐Linear Systems With Time‐Varying State Function Constraints
Authors: Sun Jing‐Jing , Zhu Shan‐Liang , Guo Yao‐Yao , Han Yu‐Qun 
Published: January 2025

ABSTRACTThis paper studies the finite‐time control problem of a class of switched non‐linear systems under time‐varying state constraints and proposes an adaptive finite‐time controller based on a multi‐dimensional Taylor network (MTN). Firstly, the time‐varying tangent barrier Lyapunov functions (TBLFs) are constructed to ensure that all system states are constrained within a certain range. Secondly, MTNs are used to estimate the unknown non‐linear functions during the controller design process. The proposed control scheme ensures that the tracking error of the system can converge to a small domain of the origin in a finite‐time. At the same time, all the signals of the closed‐loop system are semi‐global practical finite‐time stable (SGPFS) and all states satisfy the defined time‐varying state constraints. Finally, the effectiveness of the control strategy is verified through numerical simulation examples and practical simulation examples.

AbstractAqueous hydrogen gas batteries (AHGBs) are demonstrated to possess ultra‐long lifetimes and high reliability, making them highly promising for large‐scale energy storage applications. Consequently, the development of high‐efficiency, low‐cost, and scalable hydrogen oxidation/reduction (HOR/HER) catalytic electrode materials is essential for promoting the industrialization of AHGBs. In this study, a large‐scale processible platinum‐ruthenium‐nickel multimetallic aerogel catalyst is presented with high pH‐universal HOR/HER catalytic activity synthesized by a facile method, exhibiting the potential for industrial‐grade production. Theoretical calculations reveal that the synergistic adsorption on different metal atoms optimizes the reaction path, thus enhancing the catalytic activity. Fabricated with an extremely low loading (≈30 µgPtRu cm−2), both alkaline nickel‐hydrogen (Ni‐H2) battery and acidic manganese‐hydrogen (Mn‐H2) battery demonstrate high performance with lifetimes exceeding 2500 h at 0.5 C and over 1500 cycles at 20 C, respectively, significantly surpassing those with commercial Pt/C catalyst. Notably, a 5 Ah scaled‐capacity Ni‐H2 battery is assembled and exhibits an exceptional energy density of 169 Wh kg−1 with a low cost of US$ 74 kWh−1 based on all components of the cell, providing possibilities for the commercialization of AHGBs in large‐scale energy storage applications in the future.

Published: January 2025

AbstractIn the development of nasal‐to‐brain (N2B) drug delivery systems, the key challenge lies in penetrating the mucus, crossing the nasal epithelial barrier, and achieving broad distribution within the central nervous system (CNS) while ensuring biosafety. Non‐biomimetic delivery systems raise concerns regarding metabolism, while biomimetic systems, though safer, still face premature drug release into nasal tissues and limited distribution. Moreover, the N2B transport mechanisms of most existing drug delivery systems remain inadequately understood. This study proposed an efficient nasal‐to‐brain delivery system based on tetrahedral framework nucleic acids (tFNAs). These nanostructures, ≈10 nm in size, possess densely negative‐charged surfaces that help evade protein capture in mucus, facilitate rapid penetration of the mucus layer, and travel along the olfactory and trigeminal nerve axons to achieve widespread distribution in the CNS. The transport pathway is clearly elucidated. Additionally, tFNAs are used to deliver peptide via intranasal administration to treat sepsis‐associated encephalopathy (SAE). Results showed that tFNA‐NAP can regulate microglial activity, reduce neuronal damage, and improve behavioral outcomes. Moreover, both short‐ and long‐term safety experiments revealed no adverse effects. In summary, the development of the tFNA‐based N2B delivery system fills a gap in this field, offering a non‐invasive treatment approach for CNS diseases.

AbstractLight‐triggered chemical reactions have demonstrated great potential for advanced cell guidance, on‐demand release of therapeutics, and complex patterning in four dimensions. Current strategies rely on the cleavage of a light sensitive bond, while several protein and therapeutic release systems are designed using a hydrolytically labile bond. To bridge the gap between externally controlled light regulated transformations and intrinsically controlled hydrolytically labile bonds, a new family of light‐triggered photocages that upon conjugation to target proteins form more or less hydrolytically (un)stable imine, hydrazone, and oxime bonds is reported. The three photocages follow a dose‐dependent relationship using ultraviolet and near‐infrared radiation and the one‐ and two‐photon uncaging can be controlled in discrete volumes down to at least 10 µm precision. Upon photoirradiation, the exposed latent amino‐, hydrazino‐, and hydroxylamino‐moieties readily react with a variety of proteins, and complimentary sustained release can be achieved. The relative release rate of imine‐, hydrazone‐, and oxime‐bound proteins enable control over cell fate on hydrogels using two neuroblastoma cell lines. These results are anticipated to open new avenues for advanced materials where region‐specifical degradability is central, such as for complex protein photopatterns, cell‐guided hydrogels, and for programmable materials using photomediated dynamic covalent chemistry and photoclick chemistry.

Abstract1,4‐naphthoquinone (NQ) is anticipated to emerge as a promising electrode material for designing high‐performance aqueous proton batteries (APBs), attributed to its high theoretical capacity and flexible designability. However, its high solubility and sluggish kinetics are not conducive to long‐term cycling stability and high‐rate capability. Herein, a unique molecular structure design strategy is proposed to construct effective p‐π conjugated structures by inducing the p‐electrons in substituent groups and 𝜋‐electrons on naphthalene rings. Theoretical calculations and experimental results indicate that the p‐π conjugation effect of 2,3‐dichloro‐1,4‐naphthoquinone (2Cl‐NQ) and 1‐hydroxy‐1,4‐naphthoquinone (1OH‐NQ) greatly reduces molecular polarity and expands the π‐conjugate system, which endows them with minimal solubility and superior structural stability, thereby achieving excellent cycling stability with 99.53% and 98.62% capacity retention after 1800 cycles, respectively. Moreover, the p‐π conjugated structures induce a narrowed bandgap, improving electronic conductivity and redox kinetics, thereby significantly enhancing their rate capability. When coupling with perylene‐3,4,9,10‐tetracarboxylic dianhydride (PTCDA) anode, the full battery of 2Cl‐NQ//PTCDA exhibits a high specific capacity of 173 mAh g−1 at 15 A g−1, maintaining 73.2% capacity retention after 40 000 cycles and demonstrating exceptional cycling performance even at −20 °C. This work provides valuable insights and guidance for designing high‐performance energy storage materials for APBs.
