Dear Editor,Pyruvate dehydrogenase complex(PDHc) is a large multienzyme assembly(Mr = 4–10 million Daltons) consisting of three essential components: pyruvate dehydrogenase(E1p), dihydrolipoyl transacetylase(E2p), and dihydrolipoyl dehydrogenase(E3). These three enzymes perform distinct functions sequentially to catalyze the oxidative decarboxylation of pyruvate with formation of nicotinamide adenine dinucleotide(NADH) and acetyl-coenzyme A(Patel and Roche, 1990).

Optoelectronics Letters 2025年

作者： ZHANG Weihua MU Jinlin WANG Hao WANG Dong YU Haozheng TAO Yipeng Engineering Research Center of Optoelectronic Devices and Communication Technology，Ministry of Education， Tianjin Key Laboratory of Film Electronic and Communication Devices， School of Integrated Circuit Science and Engineering， Tianjin University of Technology Engineering Infrastructure Department，Autonomous Driving Department Xiaomi EV Company Ltd

A temperature-insensitive micro-displacement sensor based on a spindle-shaped single mode fiber (SMF) is presented and demonstrated. The SMF is bent into a balloon-shaped SMF and burned into a spindle-shaped SMF by a flame. Due to the bending of the fiber， part of the incident light leaks from the fiber core into the fiber cladding， which excites higher order cladding modes. Therefore， modal interference occurs. The experimental results show that the maximum sensitivity of the sensors is -203 pm/μm when micro-displacement varies from 0 to 80 μm. The sensors are insensitive to temperature in the range of 20-70℃. In addition， the sensors have the advantages of simple structure， low cost， small volume， high sensitivity and stability， which can be widely used in numerous high-precision industrial measurements and civil engineering structure monitoring fields.

Throughout this communication, it has been reported the theoretical outcomes of doping of various additive elements on the glass composition Se60-Te20-Ge15-M5 (M = Sn, Zn, Sb). The dependence on mean coordination number, mean bond energy, the transition temperature of the glass, and cohesive energy with various additive elements have been studied based on topological considerations. A comprehensive investigation of various parameters like mean coordination number, bond-stretching and bond-bending parameters, energy gap, cohesive energy, glass transition temperature, and mean bond energy has been carried out. By deploying basic ideas grounded in average coordination numbers and bond energies, the cohesive energies of the systems have been estimated by computing the number of each type of predicted bond. Band gap energies of the systems have been estimated theoretically and the Sb-doped system possesses the lowest energy band gap with a value of 1.39 eV. The chemically ordered network model and constraints theory have been used to discuss these obtained results. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

An increasingly important field of research has emerged in recent decades: the interaction between urban infrastructure, human lives, and natural disasters. Analysis and reaction to natural disasters have made extensive use of deep learning (DL) techniques using semantic segmentation networks. The aim of this research is to develop novel method in disaster-based geographical region changes and climate change detection utilising DL model. Here, input is collected as disaster-based geographical region and climate change dataset as well as processed for noise removal and smoothening. Then, this image feature has been extracted and classified using watershed U-net component analysis with Hopfield variational fuzzy encoder neural networks. The fundamental component of the suggested approach is a deep learning procedure that makes it possible to identify soccer fields and analyse helicopter landing sites. The technique uses satellite photos and provided geographic data to train a deep learning autoencoder. Experimental analysis has been carried out in terms of classification accuracy, specificity, sensitivity, ROC, and F-measure. The proposed technique obtained 96% of classification accuracy, 94% of sensitivity, 98% of specificity, 95% of ROC, and 97% of F-measure. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2025.

It is challenging to maintain effective and secure access control in modern workplaces due to unauthorized access, RFID tag cloning, and the vulnerabilities of single-layer authentication systems. Conventional methods, e.g., paper logs and independent RFID authentication, are vulnerable to security intrusions, identity spoofing, and employee tracking inefficiencies. To overcome these issues, this paper introduces GUARDTRACK, an IoT-based smart entry system that integrates Wi-Fi-based tracking and RFID-OTP authentication for enhanced security. The system consists of two prime parts. First, an ESP32 Wi-Fi module tracks the attendance of workers by recognizing static IP assignments when registered devices enter the network. Second, a Security Room authentication system requires workers to scan an RFID card, triggering an OTP (One-Time Password) delivered via a GSM module to be received at their registered telephone number. Entry is granted only after successful verification of OTP for providing multi-layered protection. Experimental testing confirms that GUARDTRACK securely blocks unauthorized access while permitting easy entry for authorized personnel. The system offers high tracking accuracy, real-time authentication, and high RFID cloning resistance, providing a cost-effective and scalable access control solution.

Lightweight image super-resolution aims to reconstruct high-resolution images from low-resolution images using low computational costs. However, existing methods result in the loss of middle-layer features due to activation functions. To minimize the impact of intermediate feature loss on reconstruction quality, we propose a Feature Interaction Weighted Hybrid Network (FIWHN), which comprises a series of Wide-residual Distillation Interaction Block (WDIB) as the backbone. Every third WDIB forms a Feature Shuffle Weighted Group (FSWG) by applying mutual information shuffle and fusion. Moreover, to mitigate the negative effects of intermediate feature loss, we introduce Wide Residual Weighting units within WDIB. These units effectively fuse features of varying levels of detail through a Wide-residual Distillation Connection (WRDC) and a Self-Calibrating Fusion (SCF). To compensate for global feature deficiencies, we incorporate a Transformer and explore a novel architecture to combine CNN and Transformer. We show that our FIWHN achieves a favorable balance between performance and efficiency through extensive experiments on low-level and high-level tasks. © 1999-2012 IEEE.
