Manned travel to and colonization of the Moon and Mars demand a comprehensive approach that extends far beyond the ability to transport humans on powerful rockets and spacecraft. The sustain ability of human life in these hostile environments is a critical consideration, prompting extensive research to understand how humans might survive and establish themselves beyond Earth. Therefore, this article covers a scoping review, and a point of view of the most relevant published papers is analyzed. The results reveal that the continuous evolution of medical technology and risk analysis have facilitated improved design, research, and development in crucial areas such as engineering and biomedical sciences. Space life support encompasses three fundamental issues: human health and performance, environmental control and habitability, and radiation risks. These aspects are pivotal in ensuring the survival and well-being of astronauts during extended missions in space, which are critical to overcome the technological and biological challenges posed by exploring and colonizing extraterrestrial environments. In addition, the significant challenges associated with manned travel and colonization of other celestial objects underscore the need for continued innovation and collaboration across various scientific and engineering disciplines. Finally, as technological and scientific advancements continue, the prospect of colonizing the Moon and Mars becomes increasingly achievable, paving the way for the next chapter in human exploration and expansion into the cosmos.

Task offloading from many Internet of Things (IoT) devices to a mobile edge computing (MEC) system, consisting of multiple collaborative edge servers (CES), results in reduced task execution delay as well as energy consumption. However, exploitation of computation resources of CESs incurs additional cost. Existing works in the literature either focused on minimizing execution latency or energy. In this paper, we have developed a task offloading policy that aims at making a trade-off between device utility and execution cost. The utility is defined as a function of task execution latency and energy consumption of energy harvesting IoT devices. The task offloading problem is formulated as a subset selection problem that makes the desired trade-off. The offloading problem is proven to be NP-hard and thus we develop a meta-heuristic approach, namely SCOPE, inspired by Social Cognitive Optimization (SCO) to obtain the desired Polynomial time Execution. The results show its potency compared to the state-of-the-art methods in terms of task execution latency, energy consumption, utility per unit cost and task drop rate. © 2022, The Authors.

Advancements in wearable robots aim to improve the users' motion, performance, and comfort by optimizing, mainly, energetic cost (EC). However, EC is a noisy measurement with a physiological delayed response that requires long evaluation periods and wearing an uncomfortable mask. This study aims to estimate and minimize an EMG-based objective function that describes the natural energetic expenditure of individuals walking. This objective is assessed by combining multiple electromyography (EMG) variables from the EMG intensity and muscle synergies. To evaluate this objective function simply and repeatedly, we prescribed step frequency (SF) via a metronome and optimized this frequency to minimize muscle activity demands. Further, a linear mixed-effects model was fitted for EC, with the EMG variables as fixed-effects and a random intercept that varies by participant. After the model was fitted to the data, a cubic polynomial was used to identify the optimal SF that reduces the overall EMG-based objective function. Our analysis outlines that the proposed objective function is comparable to the EC during walking, the primary objective function used in human-in-the-loop optimization. Thus, this EMG-based objective function could be potentially used to optimize wearable robots and improve human-robot interaction.

New technological advances have brought tools to increase the scope of the human outside the world. However, it is necessary more research to achieve the challenges of leaving the earth. Thus, some solutions applied on this planet could be used as inspiration to be used in other environments besides scouting or mapping. For this reason, a micro review to collect some projects about unmanned aerial vehicles (UAV) applied to agriculture, has been done to propose possible solutions to space farming due to the relevance of having a self-sufficient food source on long trips or settlements on other planets. In addition, it is suggested the plausible adaptation of the projects currently developed to put in charge of possible tasks that can be accomplished by their functionality and limitations. For this reason, the research line of Controlled Environment Agriculture (CEA) in the Division of Biomechatronics and Life Support Systems at the Center for Space Emerging Technologies (C-SET) worked in collaboration with the Department of mechatronics Engineering of the Corporación Universitaria del Huila presents a technical literature micro-review to encourage the scientist to create novel UAVs starting from the now working on earth to improve their performance in demanding scenarios like low gravity or thin atmosphere. In conclusion, it is mandatory to start the automatization of as many as possible tasks that could be needed where are limited resources such as labor or time to end all the assignments of the mission resulting that the implementation of UAVs as a solution for future space colonies.

Formal verification is a powerful tool to show functional correctness of task and workflow descriptions representing robot-based manufacturing processes. A prerequisite is the integration of the process into a well-structured modeling and design architecture. In this paper, we propose a layer-based formal verification scheme that accepts BPMN-based input models. The integrated composition of tools enables state-space comprehensive verification targeting a set of user-defined verification goals. The importance of formal verification scheme is highlighted by our methodology which strictly supports a model refinement and abstraction approach. Since the complexity and size of robot application process models are steadily increasing this feature in combination with a clear verification methodology is a substantial contribution towards industrial acceptance.

Cationic redistribution induced spin-glass and cluster-glass states in spinel ferrite

Physical Review B 2022年第17期106卷 174402-174402页

Murugavel Pervoskite Materials Laboratory Functional Oxides Research Group (FORG) Department of Physics Indian Institute of Technology Madras Chennai 600036 India Solid State Physics Department of Materials Science and Engineering Uppsala University Box 35 75103 Uppsala Sweden Department of Robotics and Mechatronics Engineering Daegu Gyeongbuk Institute of Science and Technology (DGIST) Daegu 42988 Republic of Korea

The effect of the cationic redistribution on the complex spinel structure and magnetic properties were investigated in Zn0.7Cu0.3Fe2O4 ferrite. X-ray photoelectron spectroscopy and x-ray diffraction studies revealed that the system exhibits a mixed spinel structure with Fe3+, Zn2+, and Cu2+ occupying both tetrahedral and octahedral sublattices. The DC magnetization results revealed the absence of long-range magnetic order in the system. Furthermore, the AC susceptibility data analysis using dynamic scaling laws suggests that the system exhibits magnetic relaxation below two different temperatures: (i) a spin-glass–like transition at low temperature (∼49.2K) with critical exponent 10.3 and spin-flip time ∼10−11s, and (ii) a cluster-glass–like transition at higher temperature (∼317K) with critical exponent 4.6 and spin-flip time ∼10−10s. The existence of glassy behavior and magnetic memory effects below the spin-glass transition temperature proves that the system is in nonequilibrium dynamical state. The coexistence of spin-glass and cluster-glass along with the thermal hysteresis between these two transitions could widen the technological applications of these systems.

With its growing use in industry, ROS is rapidly becoming a standard in robotics. While developments in ROS 2 show promise, the slow adoption cycles in industry will push widespread ROS 2 industrial adoption years from now. ROS will prevail in the meantime which raises the question: can ROS be used securely for industrial use cases even though its origins didn’t consider it? The present study analyzes this question experimentally by performing a targeted offensive security exercise in a synthetic industrial use case involving ROS-Industrial and ROS packages. Our exercise results in four groups of attacks which manage to compromise the ROS computational graph, and all except one take control of most robotic endpoints at desire. To the best of our knowledge and given our setup, results do not favour the secure use of ROS in industry today, however, we managed to confirm that the security of certain robotic endpoints hold and remain optimistic about securing ROS industrial deployments.

Audio-driven single-image talking portrait generation plays a crucial role in virtual reality, digital human creation, and filmmaking. Existing approaches are generally categorized into keypoint-based and image-based methods. Keypoint-based methods effectively preserve character identity but struggle to capture fine facial details due to the fixed points limitation of the 3D Morphable Model. Moreover, traditional generative networks face challenges in establishing causality between audio and keypoints on limited datasets, resulting in low pose diversity. In contrast, image-based approaches produce high-quality portraits with diverse details using the diffusion network but incur identity distortion and expensive computational costs. In this work, we propose KDTalker, the first framework to combine unsupervised implicit 3D keypoint with a spatiotemporal diffusion model. Leveraging unsupervised implicit 3D keypoints, KDTalker adapts facial information densities, allowing the diffusion process to model diverse head poses and capture fine facial details flexibly. The custom-designed spatiotemporal attention mechanism ensures accurate lip synchronization, producing temporally consistent, high-quality animations while enhancing computational efficiency. Experimental results demonstrate that KDTalker achieves state-of-the-art performance regarding lip synchronization accuracy, head pose diversity, and execution efficiency.
