 Abstract

This paper presents a physics-based 3D humanoid locomotion system trained entirely via reinforcement learning using Proximal Policy Optimization (PPO) within the Unity ML-Agents framework. A multi-joint humanoid agent learns stable, goal-directed bipedal walking using proprioceptive observations including joint angles, angular velocities, body orientation, and binary foot-ground contact signals, without any hand-crafted controllers or motion capture data. The continuous action space drives 35 joint torques through PD control with joint limit constraints. A multi-term reward function promotes forward progress, upright posture, and contact discipline while penalizing falls and degenerate behaviors. Training employed 25 parallel agents over 2.8 million timesteps, completing in 1.23 hours. The final policy (ragdoll_smooth_v2) achieved a cumulative reward of +845.38, compared to approximately -12,000 at initialization, demonstrating significant policy improvement. The trained policy is exported as an ONNX model enabling real-time inference deployment. TensorBoard metrics including cumulative reward, episode length, policy loss, value loss, and curiosity loss confirm stable convergence and consistent gait emergence throughout training.

Abstract Western Rajasthan is a globally significant repository of petrified wood, offering crucial paleontological and geological insights into the Earth's deep past. The region contains ancient fossilized forests - predominantly found in the Jaisalmer and Barmer basins - that document the climatic transitions and shifting depositional environments of the Indian subcontinent over millions of years. The petrified wood of western Rajasthan is deeply tied to the geological history of the Thar Desert and surrounding sedimentary basins. The petrified wood of western Rajasthan is deeply tied to the geological history of the Thar Desert and surrounding sedimentary basins. The fossils are preserved within the Mesozoic strata (specifically the Lathi and Jaisalmer formations) and the Cenozoic Barmer Hill Formation. The ancient trees were swept into deltaic or marine environments, rapidly buried under thick sediments, and subjected to groundwater rich in silica. Over millions of years, organic plant matter was replaced with silicate minerals like quartz via permineralization, cell by cell. Akal Wood Fossil Park (Jaisalmer): Designated as a National Geological Monument, this 21- hectare park is the most famous site for petrified wood. It houses 25 petrified tree trunks (including extinct gymnosperms) dating back to the Early Jurassic period (~180 million years ago).

 Abstract

The rapid growth of artificial intelligence (AI) is having a major impact on various creative fields, including music. This study focuses on the role of artificial intelligence in music and examines in detail how it functions as a threat or an opportunity, particularly in the fields of creativity, music production and education. The research primarily follows the development of technology in the field of music, with a focus on the digitisation of traditional practices. Later, he explores the use of artificial intelligence in music composition, in production processes and in the enhancement of voice, and he focuses on how these technologies are changing the role of musicians and producers. Especially focused on AI-based tools to help you compose, mix, master and personalize learning in music education. The study also identifies possible challenges associated with artificial intelligence, including concerns about originality, ethical implications and the potential replacement of human musicians. It also highlights the opportunities that AI creates, such as increased accessibility, efficiency and innovation in music creation and teaching. Through a balanced analysis, this research seeks to understand the evolving relationship between human creativity and machine intelligence. The findings suggest that, while artificial intelligence introduces some risks, it is largely acting as a supporting tool to enhance human potential rather than replacing it. The study concludes by emphassising the importance of adapting to technological progress while preserving the essence of human creativity in music through ethical instruments and practices in music, production and education.

 Abstract

Railway tracks form the backbone of modern transportation systems, enabling safe and efficient movement of passengers and goods across long distances. However, track cracks, structural defects, and unexpected obstacles such as animals can lead to serious accidents, derailments, and operational disruptions. This paper presents an Embedded IoT Framework for Real-Time Railway Track Integrity Assessment and Obstacle Detection using Arduino Nano. The proposed system integrates an IR sensor for crack detection, an ultrasonic sensor for obstacle identification, a NEO-6M GPS module for location tracking, and an ESP8266 Wi-Fi module for real-time data transmission. The system is mounted on a movable platform driven by BO motors and controlled through an L293D motor driver to perform continuous inspection of railway tracks. Upon detection of a crack or obstacle, an alert is generated through a buzzer, while location details are transmitted to the Blynk application for remote monitoring. The developed framework reduces dependency on manual inspection, improves detection accuracy, enhances operational efficiency, and contributes to safer railway transportation through continuous automated track surveillance and timely fault reporting.

 Abstract

The 21st century's technological boom has paradoxically fueled lifestyle disorders like dyslipidemia--a major cardiovascular risk factor characterized by abnormal blood lipid levels. Ayurveda, India's ancient health science, views health as complete well-being beyond mere absence of disease. Classical texts describe Shonita Abhishyanda--excess Kapha and Medodhatu in Rasa-Rakta--as a Santarpanajanya Vyadhi matching dyslipidemia's clinical profile. Arising from Virudhahara and over-nourishment, Shonita Abhishyanda causes Srotorodha and progresses to Sthaulya, Hridshula, and Margavarana complications, paralleling hyperlipidemia's atherosclerotic sequelae. This review correlates their etiology, pathophysiology, and clinical features, offering an integrative Ayurvedic framework for early detection and holistic lipid disorder management.

 Abstract

The automotive B-pillar is one of the most critical structural members in a vehicle body, playing a significant role in occupant protection during side-impact collisions. The present work focuses on the crashworthiness analysis and optimization of an automotive B-pillar using finite element analysis techniques. A detailed B-pillar model was developed and meshed using HyperMesh, while impact simulations were performed using LS-DYNA under dynamic loading conditions. Initially, a baseline B-pillar model was analyzed to evaluate its structural response in terms of displacement, stress, strain, and energy absorption. To improve crash performance and reduce structural weight, a systematic optimization approach was adopted. The study involved material substitution using steel DP1000 steel, aluminium alloy, and carbon fiber reinforced polymer (CFRP), followed by thickness reduction and slot introduction in low-stress regions. Further design modifications were implemented to enhance stiffness and control deformation. The study highlights the effectiveness of finite element analysis as a cost-effective tool for evaluating and optimizing automotive safety components. The findings provide valuable insights for the development of lightweight and high-performance B-pillar structures capable of meeting modern vehicle safety requirements.

 Abstract

International labor migration has become a defining feature of Nepal's development trajectory, generating substantial remittance inflows that contribute significantly to household livelihoods and the national economy. However, the extent to which remittance-led development translates into sustainable improvements in household well-being remains contested. This study examines the socioeconomic impacts of labor migration on migrant families left behind in Nepal, with particular attention to household vulnerability and institutional responses. Using a convergent parallel mixed-methods design, the research combines quantitative survey data from 400 migrant households with qualitative evidence from six Focus Group Discussions and 18 Key Informant Interviews conducted across Rupandehi, Palpa, and Myagdi districts. The findings demonstrate that while remittances enhance household income, improve access to education and healthcare, and support daily consumption, their developmental potential is constrained by persistent debt burdens, limited productive investment, and continued dependence on overseas employment. The study further reveals that left-behind women experience increased responsibilities in household management, agriculture, and caregiving, often without corresponding gains in decision-making authority. Children and elderly family members face varying degrees of emotional, educational, and care-related challenges associated with prolonged family separation. At the institutional level, local governments possess important mandates to support migrant households, yet their responses remain limited due to resource constraints, competing development priorities, and weak integration of migration concerns into local planning processes. The study argues that remittance-led development alone cannot address the multidimensional vulnerabilities experienced by migrant families. Strengthening institutional capacity, expanding local social protection mechanisms, and promoting productive use of remittances are essential for transforming migration into a more inclusive and sustainable development pathway in Nepal.
