Abstract

Quantum coherence has been shown to play a crucial role in optimizing energy transfer in photosynthetic systems, especially in the Fenna-Matthews-Olson (FMO) complex, which is responsible for efficiently capturing light energy in photosynthetic bacteria. While quantum coherence is often considered fragile and short-lived in biological systems, recent studies have indicated its potential for sustaining long-lived coherence, facilitating highly efficient energy transfer. This research investigates the implications of long-lived quantum coherence in the FMO complex for energy transfer efficiency, exploring how coherence persistence enhances the system’s performance. The objective of this study is to analyze the effects of long-lived quantum coherence on energy transfer efficiency in the FMO complex under varying environmental conditions, such as temperature and bath coupling. The results demonstrate that long-lived quantum coherence directly correlates with higher energy transfer efficiency, with temperature and environmental factors playing a significant role in maintaining coherence. The study shows that the FMO complex utilizes quantum coherence as an active resource to optimize energy conversion, achieving efficiencies well beyond classical expectations. In conclusion, this research underscores the importance of quantum coherence in biological energy transfer processes and offers insights into bio-inspired quantum systems for efficient energy harvesting.

Abstract

Cultural heritage is a vital aspect of community identity and history, yet many regions face challenges in preserving and promoting their heritage in the face of modern economic pressures. Traditional tourism practices often lead to the commercialization and degradation of cultural sites, while communities struggle to benefit economically from their heritage. Augmented Reality (AR) technology offers a promising solution by providing immersive, interactive experiences that can both preserve and promote cultural heritage while supporting sustainable tourism. This study explores the implementation of an AR-based digital-preneurship start-up model designed to revitalize cultural heritage through tourism while empowering local communities. The research employs a mixed-methods approach, combining quantitative surveys and qualitative interviews with both local stakeholders and tourists. The findings reveal that the AR platform significantly enhanced both tourist engagement and local economic outcomes, increasing community participation in tourism-related activities and boosting income for local businesses. The study concludes that AR-based digital-preneurship offers a scalable, sustainable model for cultural heritage revitalization, providing communities with a new avenue for economic development and cultural preservation. This research contributes to the growing body of knowledge on the intersection of technology, entrepreneurship, and sustainable tourism.

Abstract

Hybrid quantum systems that integrate solid-state qubits with superconducting circuits have emerged as a promising architecture for scalable quantum information processing. Achieving strong coherent coupling between distinct quantum subsystems, such as spin ensembles and microwave resonators, remains a critical challenge in realizing hybrid quantum technologies. This study aims to engineer and characterize a hybrid platform that couples nitrogen-vacancy (NV) centers in diamond with a superconducting coplanar waveguide resonator. A combination of cryogenic microwave spectroscopy and time-domain measurements was employed to evaluate coupling strength, coherence times, and collective spin photon interactions at millikelvin temperatures. The experimental results demonstrated a vacuum Rabi splitting of 22 MHz, confirming the realization of a strong coupling regime between the NV spin ensemble and the superconducting resonator. The coherence lifetime of the NV centers remained above 100 ?s under optimized magnetic field alignment, ensuring stable quantum-state transfer. The findings reveal that hybrid systems combining spin-based and superconducting components can serve as viable interfaces for quantum memory and quantum communication nodes. The study concludes that engineering such strong spin–photon coupling represents a foundational step toward the development of coherent, scalable hybrid quantum networks.

Abstract

Dengue Fever remains a significant public health issue in Indonesia, with frequent outbreaks exacerbated by varying climatic conditions and human mobility. Understanding the dynamics of its transmission is critical to developing effective control strategies. This study aims to develop a mathematical model that incorporates climate variability and human mobility to assess the transmission dynamics of Dengue Fever in Indonesia. The model utilizes a compartmental framework, where the population is divided into susceptible, infected, and recovered individuals. The impact of climate factors such as temperature and rainfall, along with human mobility patterns, is integrated through differential equations. The study uses historical epidemiological data from the Indonesian Ministry of Health, alongside climate data from the Indonesian Meteorological Agency and human mobility data derived from mobile phone usage and transportation systems. Numerical simulations are conducted to predict the effects of climate variability and mobility on Dengue Fever outbreaks. Results indicate that both climate change and human mobility significantly influence the frequency and intensity of outbreaks, with certain regions being more vulnerable to epidemic peaks. The study concludes that incorporating environmental and social factors into epidemiological models can enhance the accuracy of Dengue Fever predictions and inform targeted intervention strategies.

Abstract

Cell-based therapies for myocardial infarction (MI) are critically limited by poor acute cell retention and viability following direct injection. The harsh, ischemic microenvironment and mechanical washout result in massive cell death, neutralizing therapeutic potential and leading to failed clinical translation. This research aimed to design, synthesize, and evaluate a novel, injectable, thermosensitive hydrogel as a “pro-survival” cell delivery vehicle. The objective was to determine if this biomaterial could solve the critical failure points of retention and viability, thereby enhancing the therapeutic efficacy of mesenchymal stem cells (MSCs) post-MI. A composite hydrogel (Poloxamer/Hyaluronic Acid) was characterized in vitro for its rheological properties (LCST), mechanical stiffness, and cytoprotective capacity under ischemic stress. Its in vivo efficacy was then evaluated in a rat MI model (LAD ligation). The hydrogel+MSCs group (G5) was compared against controls (saline, MSCs-in-saline) via serial echocardiography and post-mortem histomorphometry. In vitro, the hydrogel confirmed ideal thermosensitivity (LCST 37.1°C) and cytoprotection (2.5-fold increase in ischemic cell survival). In vivo, the G5 (hydrogel+MSCs) group demonstrated significantly preserved cardiac function (LVEF 45.2%) compared to the MSCs-only group (G4: 34.1%) at 28 days. This was correlated with significantly reduced infarct size and enhanced border-zone angiogenesis. The thermosensitive hydrogel functions as an essential, enabling technology. It solves the critical failure points of acute retention and viability, demonstrating that an engineered “pro-survival” delivery vehicle is a prerequisite for the successful clinical translation of cardiac cell therapy.
