3D Face Reconstruction with Feature Enhancement using Bi-FPN for Forensic Analysis
The representation of facial features in three-dimensional space plays a pivotal role in various applications such as facial recognition, virtual reality, and digital entertainment. However, achieving high-fidelity reconstructions from two-dimensional facial images remains a challenging task, particularly in preserving fine texture details. This research addresses this problem by proposing a novel approach that leverages a combination of advanced techniques, including Resnet, Flame model, Bi-FPN, and a differential render architecture. The primary objective of this study is to enhance texture details in reconstructed 3D facial images. The integration of Bi-FPN (Bi-directional Feature Pyramid Network) enhances feature extraction and fusion across multiple scales, facilitating the preservation of texture details across different regions of the face. The objective is to accurately represent facial features from 2D images in three-dimensional space. By combining these methods, the proposed framework achieves significant improvements in preserving fine texture details and overall facial structure. Experimental results demonstrate the effectiveness of the approach, suggesting its potential for various applications such as virtual try-on and facial animation. 2024 The Authors. -
3D flow and heat transfer of micropolar fluid suspended with mixture of nanoparticles (Ag-CuO/H2O) driven by an exponentially stretching surface
Purpose: The purpose of this paper is to discuss the 3D micropolar hybrid (Ag-CuO/H2O) nanofluid past rapid moving surface, where porous medium has been considered. Design/methodology/approach: The model of problem was represented by highly partial differential equations which were deduced by using suitable approximations (boundary layer). Then, the governing model was converted into five combined ordinary differential equations applying proper similarity transformations. Therefore, the eminent iterative RungeKuttaFehlberg method (RKF45) has been applied to solve the resulting equations. Findings: Higher values of vortex viscosity, spin gradient viscosity and micro-inertia density parameters are reduced in horizontal direction, whereas opposite behaviour is noticed for vertical direction. Originality/value: The work has not been done in the area of hybrid micropolar nanofluid. Hence, this article culminates to probe how to improve the thermal conduction and fluid flow in 3D boundary layer flow of micropolar mixture of nanoparticles driven by rapidly moving plate with convective boundary condition. 2020, Emerald Publishing Limited. -

3D-Printed MOFCuO/TiO2 Energy Device for Continuous Self-Charging Power Generation
The electric nanogenerator offers an easy and affordable way to capture energy and operates on the premise of energy conversion. Contact electrification-based tribological energy harvesting through the interaction between tires and road surfaces, represents a highly promising renewable resource with a significant estimated potential. One of the important factors that decides the performance and application of these nanogenerators is the material used for its fabrication. In this work, we introduced a novel energy harvester comprised of defect-engineered Metal Organic Framework (MOF) templated CuO/TiO2 (MCT) based triboelectric layer integrated with a 3D printed substrate for a smart power wheel. The comprehensive properties of the material are revealed by the surface potential, structural, morphological, and electrical studies, which validate MOF as a feasible choice for energy harvesting applications. The MCT-based triboelectric nanogenerators (TENGs) generate a sustainable output of ?1.6V in flexible cantilever mode. The smart power-wheel system successfully showed a ? 400% enhancement in the output performance due to the combined effects of heating and bending. The detailed density functional theory (DFT) insight in Cu/O vacancies synergistically promotes TiO2?CuO charge transfer through flexible Cu+/Cu2+ redox states, facilitates electron mobility, and enhances the overall energy conversion efficiency. Overall, this study broadens the range of functional materials available for 3D printing and promotes the adoption of 3D-printed triboelectric devices in batteryless intelligent applications within smart automobiles. 2026 Wiley-VCH GmbH. -
3Rs management: Advances and innovations in waste management and treatment
The increasing industrialisation and fast growth do not only pose problems related to the allocation of resources and powers, but also severely challenge the natural environment. Environmental degradation such as contaminated water, sinking groundwater levels, unhealthy soils, and polluted air has become a harsh reality in many parts of the world. One result of a rapid urbanisation, a slowly reducing gap between urban and rural, changing consumption patterns, and a growing population is the problem of waste. However, although it is the duty of the urban local bodies (ULBs) to address the issue of waste, tight budgets, inefficient organisation, has rendered a situation that has little hope for alleviation in the near future. This chapter aims to understand the concept of waste management through 3Rs. The focus is to identify the contemporary 3Rs practices and also develop advanced strategies for the same. 2024 by IGI Global. -
3TFL-XLnet-CP: A Novel Transformer-Based Crop Yield Prediction Framework with Weighted Loss Based 3-Tier Feature Learning Model
The advancement of crop yield prediction through artificial intelligence (AI) has gained significant attention. However, the existing AI-based approaches for maximizing agricultural productivity, specifically in crop yield prediction, have not consistently delivered satisfactory results. In response to this challenge, we propose a novel framework named as Three Tier Feature Learning with XLnet based Crop Prediction (3TFL-XLnet-CP) that enhances agricultural productivity by accurately predicting crop yield. The 3TFL-XLnet-CP framework employs a three-tier feature learning approach in combination with the powerful XLnet transformer-based crop prediction model. The three-tier feature learning involves the integration of Spiking Neural Network (SNN), Graphical Neural Network (GNN), and Convolutional Neural Network (CNN) to extract distinct feature vectors from the preprocessed data. These feature vectors are then concatenated using Jaccard Similarity to measure their similarity score. Additionally, a weighted Loss function is introduced to optimize feature learning, further enhanced by a novel self-adaptive Spider Monkey Optimization algorithm (SASMO). The concatenated features are subsequently fed into the classification layer for making precise crop yield predictions. The proposed model is implemented using the Python platform and evaluated against existing models such as ANN, RNN, DNN, and BiLSTM. The comparison demonstrates the superiority of our proposed 3TFL-XLnet-CP framework in accurately predicting crop yield. The Author(s) 2025. -

50 years of statehood in Sikkim: a comprehensive study of the healthcare system
Sikkim is one of the smallest states located in the Eastern Himalayas of India. This paper is framed within the context of Sikkim commemorating 50 years of democracy on 16 May 2025, following its integration into the Indian Union on 16 May 1975. Over the past five decades, Sikkim has claimed several accolades; the state was declared Indias first fully organic state in 2016 and acclaimed as the best performing small state in cleanliness and most improved small state in governance in 2020. However, there are some paradoxes in Sikkims developmental paradigm. This paper focuses solely on the healthcare system in Sikkim, exploring various aspects such as the allocation of budget to the health sector, the condition of health institutions, the execution of different health programmes and schemes, the accessibility of health facilities, and the availability of human resources. An additional significant factor is the reliance of the states population on other states for healthcare services. Furthermore, it examines the factors that contribute to the increasing disparity between planning and implementation. 2026 The Round Table Ltd. -

5G-UFMC System For PAPR Reduction Using SRC-Precoding With Different Numerologies
Universal Filtered Multicarrier (UFMC) has been incorporated in 5G and is likely to be considered in future generations (B5G). The prominent limitation of UFMC manifests as a high Peak-to-Average Power Ratio (PAPR). Our suggested approach to address the Peak-to-Average Power Ratio (PAPR) issue in UFMC signals involves the application of diverse precoding matrices, including Square Root Raised Cosine Function (SRC), Discrete Cosine Transform (DCT), and Discrete Hartley Transform (DHT).This technique reduces the PAPR performance of UFMC signals over current state of the art methods. In square root raised cosine (SRC) precoding techniques, a novel precoding matrix is adapted for minimizing PAPR and improvement of BER respectively. Results show that the different subcarrier was applied and surpasses all existing techniques in reduction of PAPR and BER improvement. A novel SRC-Precoding technique reduces PAPR by 5dB for considering 512 sample points with QAM modulation as compared to 10dB for the conventional technique. Additionally, the Bit Error Rate Performance is maintaining 14dB when compared to conventional technique. Furthermore, the evaluation of Bit Error Rate (BER) performance and Peak-to-Average Power Ratio (PAPR) in the UFMC system reveals superior results compared to conventional technique. 2024 IEEE. -

60Co gamma irradiation and annealing effects on transport properties of antimony telluride platelets grown by physical vapor deposition
Physical vapor deposition method was employed to deposit antimony telluride (Sb2Te3) crystals in a dual-zone furnace. The microstructure, surface topography and composition of samples were characterized using X-ray diffraction, atomic force and scanning electron microscopy. Seebeck coefficient (S?c), electrical conductivity (??c) as well as power factor (PF) were enhanced for pure Sb2Te3 samples upon annealing, and the samples annealed at 473 K exhibited the highest PF of 3.16 10-3 W m-1K-2 with an enhancement of 22% in the figure of merit (Z). When the delivered dose of 60Co gamma radiation was increased from 0 to 30 kGy in the stoichiometric crystals, ??c decreased due to the decrease in mobility. As a result of the increase in S, PF and Z improved by 12.11 and 13.7%, respectively, in the 30 kGy gamma-irradiated crystals. Both RH (B?c) and S?c were positive, suggesting that the prepared Sb2Te3 crystals retained the p-type semiconductivity after these treatments.

A bibliometric analysis of compact city for sustainable urban development
This work provides a detailed bibliometric review of compact city literature for sustainable urbanism from 1983 to 2023. The compact city concept has received considerable attention as a possible approach towards solving sustainable city issues. Hence, based on the documents obtained from the Scopus database, we studied the research topics and authors, as well as the thematic development of this topic. The research used the bibliometric approach of citation analysis, keyword cooccurrence, and thematic evolution mapping. Research indicates that there is an Increased research productivity over the recent past especially in the last two decades. Among developed countries, China has become one of the most active participants in the provision of new knowledge. The thematic focus has shifted from pure and applied to complex themes like sustainability, GIS and urban design. The current trends show increasing concern about sustainability, development, and the 15-minute city model. The proposed analysis also reveals the unequal Within the group of countries, citation rates vary significantly, and the scope of methodological approaches is insufficient. In summary, this review finds that although compact city research has evolved to a certain extent, typological models are still lacking context sensitivity; international cooperation remains rather limited; and finally, many long-term outcomes have not been adequately investigated in order to unleash the full potential of compact cities as a global model of sustainable urban development.
