Summary: In this study, an alternative monitoring system was developed and tested in the TOOLING 4G project, which has the characteristics of affordability, simplicity, real-time data acquisition, intuitive GUI, and open-source firmware and software. The system uses an Arduino microcontroller-based data acquisition module to connect to a computer via a USB port. The system can visualize and record data from up to six sensors at a rate of 10 Hz, and successfully monitor an injection mold under real-world conditions, distinguishing between normal and abnormal operating patterns.

Summary: This article introduces enu, a freely-downloadable, open-source, and standalone program written in C++ for enumerating constitutional isomers and stereoisomers of a molecular formula. The program uses graph theory to enumerate all the constitutional isomers based on their canonical adjacency matrix, and the stereoisomers based on the automorphism group of this matrix. The results are reported in XML format files with canonical SMILES strings. The program allows flexible specification of the molecule family of interest and is optimized for computational efficiency. The article describes the algorithms and implementations of enu and presents illustrative applications. The enu code is available on GitHub at https://github.com/csms-ethz/CombiFF.

Summary: Complexity economics challenges the assumptions of neoclassical economics by proposing an economic system where agents are diverse, have limited information, and constantly adapt to create non-equilibrium outcomes. This perspective offers a new angle for economic research by moving away from the idea of perfectly rational agents in equilibrium.

Summary: Smart irrigation is becoming increasingly important in agriculture, but implementing it can be challenging for farmers. We have developed a low-cost, open-source IoT system for smart irrigation that can be integrated with other platforms and supports a wide range of sensors. The system has been tested on an olive farm, and the results show the advantages of using these technologies over traditional methods.

Summary: An implementation proposal is presented with the aim of globalizing sustainable technologies developed in University laboratories. This approach involves generating triple-impact projects that prioritize people and utilize technical and scientific knowledge to design global sustainable solutions. The research explores the concept of a hub for scientific research, technological implementation, and human needs, creating common environments for interaction and knowledge expansion among all stakeholders involved in technological implementation. The proposal focuses on a specific technology developed at the Universidad de Buenos Aires, which utilizes sustainable materials for water treatment, and designs virtual environments to cater to different user groups, including open design environment, academic platform, and information disclosure page. The proposed technological service aims to bridge the gap between the University and the community, enabling communities to access public financing for self-managed improvement projects and democratizing public investment for long-term sustainability.

Summary: Ammonia plays a vital role in fertilizer production, but the current production processes heavily rely on fossil fuels. A re-design of the production process is urgently needed to reduce greenhouse emissions and dependence on volatile gas markets. Renewable energy driven electrolysis provides a pathway for producing carbon-free ammonia, but balancing the variable renewable energy generation with the inflexible ammonia synthesis unit is a challenge. Green ammonia production has only been demonstrated at pilot scale, and optimizing plant configurations and scaling up production facilities is a priority. This study presents a modeling framework that consolidates previous configurations into a single framework and can be tailored to specific locations. The framework simulates the integration of renewable energy with balancing power and storage options to meet the demands of green ammonia production. The results show that while the cost of green ammonia production is higher than historical production costs, falling renewables costs and emission reduction imperatives suggest a promising future for green ammonia.

Summary: Optical imaging has a wide range of applications in the biomedical field, providing visualization of physiological processes and aiding in disease diagnosis and treatment. Unexcited light source imaging technologies, such as chemiluminescence imaging, bioluminescence imaging and afterglow imaging, have gained attention due to their lack of excitation light interference, high sensitivity, and high signal-to-noise ratio. This review highlights the latest advances in unexcited light source imaging technology for biomedical applications, discussing the design strategies of luminescent probes, their applications in various imaging modalities, and the future prospects of unexcited light source imaging for medical applications.

Summary: Recent infrastructure inspection has utilized deep-learning models to improve typical inspection tasks, but the need for significant amounts of data has hindered progress. To address this, researchers acquired bridge inspection data by extracting images from reports and developed four high-quality, publicly accessible datasets for bridge inspection tasks. These datasets can be used for auxiliary inspection tasks and autonomous flight path planning with the help of unmanned aerial systems.
