Mobile crawler robot for seed sowing and route planning through neuro-diffuse control

The main objective of this project is to build a mobile terrestrial robot that allows the sowing of seeds of various types of plants that are cultivated in an artisanal way. A structure based on tracked locomotion has been designed that involves the use of several sensors, DC motors, and control systems based on two Arduino boards, which together allow the mobile robot to interact with the irregular environment through which it moves. The locomotion process carried out by the seeding robot is configured through an HMI interface implemented on a touch screen, where the user chooses the type and quantity of seeds to be sown so that the robot then follows an autonomous rectilinear trajectory which is supervised and corrected utilizing a neuro-diffuse control such as ANFIS. In addition, the mobile robot has a battery feeding and charging system through solar panels, which gives it complete autonomy to carry out the work entrusted to it.

Enhancing patient-centered care: a randomized study on G-CSF administration preferences in chemotherapy-induced neutropenia.

Chemotherapy-induced neutropenia poses a significant risk to cancer patients, with pegfilgrastim being commonly used for its prevention. While pegfilgrastim can be administered via prefilled syringe or pen device, patient preferences and experiences with these delivery methods remain unclear. We conducted a prospective, open-label, randomized, observational trial (NCT05910164) at the Rafael Institute, France, comparing patient preferences for pegfilgrastim administration using a prefilled syringe versus a prefilled pen device. Patients undergoing chemotherapy and requiring pegfilgrastim were enrolled and randomized 1:1 to receive either syringe or pen first, with crossover administration. Questionnaires assessed patient preferences, learning experiences, autonomy, pain levels, emotional responses, satisfaction with nursing care, and empowerment. Among 150 randomized patients (mean age 58years; 69% female), both groups showed a preference for the pen device, with significantly higher mean scores favoring pen administration (4.94 ± 1.70 vs. 4.27 ± 1.84; p = 0.00106). Patients reported significantly lower perceived pain with pen administration and stronger positive emotions compared to syringe use. Satisfaction with nursing care was higher with syringe use. Empowerment levels were similar across groups but significantly stronger when using the pen in complete autonomy. A preference for pegfilgrastim administration via the pen device was observed, though this may have been influenced by the administration sequence and the absence of syringe self-administration. The insights gained can help inform clinical decision-making and improve patient-centered care in managing chemotherapy-induced neutropenia. NCT05910164 on June 15, 2023.

Achieving Off-Grid Refrigeration in Remote Areas: A Solar-Powered Vapor Compression Refrigerator Prototype with PCM Integration

The availability of vaccines, medicines, and perishable goods in remote or off-grid areas remains a formidable challenge. Integrating solar photovoltaic (PV) systems with refrigeration technology has emerged as a promising solution to address this critical need. This paper presents an autonomous solar-powered refrigerator prototype for off-grid refrigeration in remote areas utilising renewable energy. The system comprises a 160 W photovoltaic module, a 12/24 V DC compressor refrigerator, a lead-acid battery, and a Maximum Power Point Tracking (MPPT) controller. Its main feature is complete autonomy from the electricity grid, thanks to its standalone configuration. An experimental campaign evaluated the system's behaviour in the laboratory for 24 hours at different set-point temperatures. A water-based Phase Change Material (PCM) was implemented to improve its autonomy in severe outdoor conditions. A further experimental campaign emulated the functioning of the prototype while managing the temperature of a sample solution whose melting temperature was equal to – 21°C to ensure its liquid state during the tests. The target range for preserving the sample was defined at ± 1°C. Several real conditions have been considered, such as higher cooling loads realised through 21 litres of additional thermal mass in the refrigerator and pick and place conditions for simulating the opening and closing of the door. The results demonstrate that the solar refrigerator prototype achieves complete autonomy from the electricity grid, paving the way for solutions for preserving perishable goods such as medicines and food in unelectrified areas.

Evaluating conventional and renewable energy systems for green buildings: A case study on energy efficiency and cost optimization

This study explores two primary categories of power generation: conventional methods reliant on fossil fuels and renewable energy methods. Fossil fuel-based approaches, including natural gas and heavy fuel oil, contribute to environmental concerns due to their carbon dioxide (CO2) emissions, which are responsible for the greenhouse effect and global warming. Many nations, particularly in Europe, have implemented stringent measures to restrict CO2 emissions, imposing fines on industries that exceed emission limits. In response to these concerns, this study focuses on a green building project that aims to meet its power requirements through renewable energy sources. Various renewable energy resources will be evaluated, considering the merits and drawbacks of each technology, to identify the most suitable option for the building under investigation. Additionally, a comprehensive thermodynamic analysis will be conducted, including calculations of electrical needs such as cooling load, lighting load, and equipment load. A customized power calculator will also be developed for application in similar projects. The ultimate objective of this study is to achieve complete autonomy from the electric grid by utilizing renewable energy resources, transforming the building into a green building. The results indicate that at an outside temperature of 22 °C, the total heat gain decreases from 157.3 to 39 kW, reducing the total cost of electricity from 20,000 to 5100 AED/year. Conversely, at an outside temperature of 50 °C, the total heat gain increases from 157.3 to 196 kW, raising the total cost of electricity from 20,000 to 26,000 AED/year. These findings demonstrate the significant influence of outside temperature on the building's energy requirements and costs, underscoring the importance of considering temperature variations in energy efficiency and cost optimization strategies.

Serial Transverse Enteroplasty (STEP) for Short Bowel Syndrome (SBS) in Children: A Multicenter Study on Long-term Outcomes

ObjectivesShort Bowel Syndrome (SBS), secondary to various underlying diseases, is one of the main causes of intestinal failure in children. Surgical management by serial transverse enteroplasty (STEP), is feasible in selected cases, but results on long-term follow-up are scarce. The aim of this study was to report long-term outcomes of the STEP procedure in children with SBS. MethodsWe performed a multicenter national retrospective study reviewing medical charts of children who underwent a STEP technique between 2000 and 2022 in 6 university hospitals. Collected data included demographics, SBS history, surgical procedures, nutritional support (enteral or parenteral), STEP management, complications, and outcomes (nutritional support, digestive symptoms, growth). ResultsSTEP was performed in 36 SBS, resulting from 14 gastroschisis, 10 intestinal atresia, 8 necrotizing enterocolitis (NEC), 2 midgut volvulus, and 2 intestinal Hirschsprung disease. Median age at first STEP was 10.8 months [4.5; 63.8]. Bowel length significantly increased (47 vs 70 cm, p < 0.01), with a median gain of 16 cm [11; 25] or 34%. At surgery, 33 children had parenteral nutrition (PN). A second STEP was performed in 11 patients, at a median age of 4.2 years [2.8; 6.8]. One patient underwent a third STEP. Two children required intestinal transplantation. Median follow-up was 7 years [4.4;11.4]. Out of 33 children requiring PN before surgery, 14 children were weaned off PN. The remaining 19 children still required PN, but their dependency decreased by 19%. Out of 17 children presenting severe intestinal dilations and bacterial overgrowth, 12 became asymptomatic. Out of 20 with chronic obstructive symptoms, 8 patients still required supplementary PN whereas 12 achieved complete enteral autonomy, including 3 requiring supplementary enteral support. ConclusionSTEP technique remains a surgical option in the management of these children, enabling a decrease in PN dependency, resulting in weaning off PN in some cases, as well as an improvement of clinical symptoms.

Robotic Lobectomy with a Single Robotic Stapler from One 12-mm Port: A Multi-institutional Study.

Introduction of the robotic stapler has allowed robotic lobectomy to be performed from a surgical console in complete autonomy. The robotic stapler fits a 12-mm port, which is larger than the standard 8-mm port and increases the risk of postoperative pain. However, in many cases, to cover all possible angles of approach, two 12-mm ports are preferably used. However, limiting instrument inventory and simplifying surgical procedures are also desirable to reduce costs. In a multicenter study, we assessed the feasibility of robotic lobectomy with a single type of robotic stapler [SureForm45 Curved-Tip (SF45C); Intuitive Surgical Inc.] inserted through one 12-mm port placed at the anterior tip of the lower intercostal space. We also investigated the potential cost savings of using an additional 60-mm stapler for interlobar division. A total of 135 lobectomy cases were enrolled. In all cases, all stapling procedures were completed using the SF45C inserted from the designated 12-mm port. We found that it was potentially less expensive to use the SureForm60 stapler if more than six SF45C reloads were needed for interlobar division. However, in our series, only 1 case (0.7%) met this requirement. The use of a single type of stapler from one 12-mm port in a robotic lobectomy is technically feasible. This approach may be expected to allow for surgical simplification, minimize the risk of postoperative pain, and reduce inventory costs.

Advanced medullary thyroid carcinoma uncovered by persistently elevated procalcitonin in a patient with COVID-19.

We report the case of an 88-year-old man hospitalized for COVID-19 with persistently very high procalcitonin (proCt) levels despite infection resolution. Since proCt is an adjunct tumor marker in the diagnosis of medullary thyroid carcinoma (MTC), serum calcitonin (Ct) was also measured showing very high levels. Computed tomography (CT) scan showed the presence of a thyroid mass and neck ultrasound revealed a solid isoechoic, inhomogeneous, 50 mm nodule in the right thyroid lobe, extended into the mediastinum. Fine needle aspiration (FNA) of the thyroid nodule confirmed the diagnosis of MTC. An 18F-fluorodopa positron emission tomography/computed tomography (PET/CT) scan revealed the presence of distant metastases in ribs, vertebrae, in the right iliac wing and the liver. Since surgery was not feasible, the patient was started on cabozantinib 40 mg/dL. After 16 months the patient is still on cabozantinib at the same dose, he reports complete autonomy in daily life activities, and serum Ct is still elevated; however, the imaging evaluation does not show signs of disease progression. High procalcitonin serum values despite the absence of infection are suggestive of MTC. Advanced MTC with multiple metastases can have an indolent course and can go unrecognized for years. Cabozantinib is a valuable option for the treatment of advanced MTC.

Particle Filter Enhanced by CNN-LSTM for Localization of Autonomous Robot in Indoor Environment

Particle filters play a crucial role in indoor localization tasks where GPS or similar sensors are unavailable, owing to their adaptability to dynamic environments and contribution to precise navigation. However, despite their effectiveness in non-Gaussian and non-linear settings, particle filters face challenges such as issues with particle initialization and recovery from scenarios like robot kidnapping. These limitations impede the complete autonomy of robots, a critical aspect of their functionality. This research presents a novel solution that integrates particle filters with a CNN-LSTM network to address these challenges. Leveraging the time-series image processing capabilities of CNN-LSTMs, this architecture aids in particle filter initialization and facilitates recovery from challenging situations. The integration enhances the overall performance and autonomy of robots, making them more efficient in indoor navigation tasks.

In platform we trust(?) Concepts, problems and a case study about platform education

AbstractDigitation in education, where online platforms play a central role, has changed teaching and learning scenarios. In addition, it has brought an unprecedented array of public and private actors into the educational arena who provide schools with technological solutions for redesigning learning environments and practices. Though the arena is dominated by EdTech companies, non‐profit initiatives are not entirely absent. After a brief introduction to the main issues relating to the spread of educational platforms, this article will present a rare case of a non‐commercial educational platform developed, implemented and managed in complete autonomy by a community of university students.

Village Autonomy in Facing Village Independence

This research aims: 1) to describe the concept of Village Autonomy, 2) to describe Independent Villages, 3) to describe Village Autonomy, village autonomy towards village independence. The research method used is descriptive qualitative research with a library research approach. The results of this research are 1) The implementation of Village Autonomy is genuine, complete and complete autonomy and is not a gift from superior or supra-village government, on the contrary, the government is obliged to respect the original autonomy of the village; 2) The independent village concept is a rural development pattern based on an integrated concept starting from the input subsystem, primary production subsystem, product processing subsystem, marketing subsystem, and support services subsystem; village autonomy towards village independence is carried out through the development of rural areas to be targeted and appropriate with what is in the interests of village communities, planning mechanisms for implementing village development must be carried out starting from the bottom.

Patient decision-making in the era of transcarotid artery revascularization

ObjectiveThe National Coverage Determination on carotid stenting by Medicare in October 2023 stipulates that patients participate in a shared decision-making (SDM) conversation with their proceduralist before an intervention. However, to date, there is no validated SDM tool that incorporates transcarotid artery revascularization (TCAR) into its decision platform. Our objective was to elicit patient and surgeon experiences and preferences through a qualitative approach to better inform the SDM process surrounding carotid revascularization. MethodsWe performed longitudinal perioperative semistructured interviews of 20 participants using purposive maximum variation sampling, a qualitative technique designed for identification and selection of information-rich cases, to define domains important to participants undergoing carotid endarterectomy or TCAR and impressions of SDM. We also performed interviews with nine vascular surgeons to elicit their input on the SDM process surrounding carotid revascularization. Interview data were coded and analyzed using inductive content analysis coding. ResultsWe identified three important domains that contribute to the participants' ultimate decision on which procedure to choose: their individual values, their understanding of the disease and each procedure, and how they prefer to make medical decisions. Participant values included themes such as success rates, “wanting to feel better,” and the proceduralist's experience. Participants varied in their desired degree of understanding of carotid disease, but all individuals wished to discuss each option with their proceduralist. Participants' desired medical decision-making style varied on a spectrum from complete autonomy to wanting the proceduralist to make the decision for them. Participants who preferred carotid endarterectomy felt outcomes were superior to TCAR and often expressed a desire to eliminate the carotid plaque. Those selecting TCAR felt it was a newer, less invasive option with the shortest procedural and recovery times. Surgeons frequently noted patient factors such as age and anatomy, as well as the availability of long-term data, as reasons to preferentially select one procedure. For most participants, their surgeon was viewed as the most important source of information surrounding their disease and procedure. ConclusionsSDM surrounding carotid revascularization is nuanced and marked by variation in patient preferences surrounding autonomy when choosing treatment. Given the mandate by Medicare to participate in a SDM interaction before carotid stenting, this analysis offers critical insights that can help to guide an efficient and effective dialog between patients and providers to arrive at a shared decision surrounding therapeutic intervention for patients with carotid disease.

'ALL ABOUT MY IDEAL MENTAL HEALTH SERVICE': Users, family members and experts by experience discussing a co-designed service.

Many studies have investigated patients' understandings of how to optimise mental health services. However, only a few studies in the Italian context have involved experts by experience (EbEs), who can be ex-users, family members of ex-usersor current service collaborators. Their role is crucial in implementing collaborative service quality assessment projects. The study investigated the experience of 35 EbEs, users, and family members who carried out a 9-month fortnightly project aimed at imagining an 'ideal service'. The facilitators of the discussion groups (two EbEs) were interviewed; written reports of each meeting were produced with relevant comments, notesand specific suggestions; and content analysis was applied. The most important result concerns the effectiveness of the project management method and group leadership carried out by the two EbEs. This approach allowed for complete autonomy of the work, without professional gaze or power imbalance. Also, the ideas and specific contents focused on by the two groups offer strategies to facilitate users' entry and reception in health care centres, to reduce the stigma of mental illness, to improve the centres' physical environment, to improve organisational aspects, to keep family members actively involvedand to network mental health services with other territorial services. EbEs have proven to be key figures in ensuring equity of role in the service co-design process. This also concerns a context, the Italian one, where their role has not yet been recognised and legalised. Their contribution and ideas to improve services could be fundamental not only in mental health centres, but also in other health facilities, and could concern the entire service delivery process rather than being limited to quality assurance, according to a virtuous circle based on active participation and transformation of the role of users. This work resulted from close collaboration between the two EbEs who conducted the groups, users and family members, the university, and the psychiatrist in charge of the service. All of them contributed to the research. The EbEs, researchersand psychiatrist participated in the interpretation of the data and are the co-authors of this paper.

Important issues in proposing autonomy training in home parenteral nutrition for short bowel syndrome patients: a qualitative insight from the patients' perspectives.

The standard treatment for short bowel syndrome is home parenteral nutrition. Patients' strict adherence to protocols is essential to decrease the risk of complications such as infection or catheter thrombosis. Patient training can even result in complete autonomy in daily care. However, some patients cannot or do not want too much responsibility. However, doctors often encourage them to acquire these skills. Based on qualitative investigations with patients, we wanted to document issues of importance concerning perceptions of autonomy in daily care. Semistructured interviews were conducted with 13 adult patients treated by home parenteral nutrition using a maximum variation sampling strategy. We proceeded to a thematic analysis following an inductive approach. After achieving clinical management of symptoms, a good quality of life is within the realm of possibility for short bowel syndrome patients with home parenteral nutrition. In this context, achieving autonomy in home parenteral nutrition could be a lever to sustain patients' quality of life by providing better life control. However, counterintuitively, not all patients aim at reducing constraints by reaching autonomy in home parenteral nutrition. First, they appreciate the social contact with the nurses, which is particularly true among patients who live alone. Second, they can feel safer with the nurse's visits. Regaining freedom was the main motivation for patients in the training program and the main benefit for those who were already autonomous. Medical teams should consider patients' health locus of control (internal or external) for disease management to support them concerning the choice of autonomy in daily care for parenteral nutrition.

Characterizing Satellite Geometry via Accelerated 3D Gaussian Splatting

The accelerating deployment of spacecraft in orbit has generated interest in on-orbit servicing (OOS), inspection of spacecraft, and active debris removal (ADR). Such missions require precise rendezvous and proximity operations in the vicinity of non-cooperative, possibly unknown, resident space objects. Safety concerns with manned missions and lag times with ground-based control necessitate complete autonomy. This requires robust characterization of the target’s geometry. In this article, we present an approach for mapping geometries of satellites on orbit based on 3D Gaussian splatting that can run on computing resources available on current spaceflight hardware. We demonstrate model training and 3D rendering performance on a hardware-in-the-loop satellite mock-up under several realistic lighting and motion conditions. Our model is shown to be capable of training on-board and rendering higher quality novel views of an unknown satellite nearly 2 orders of magnitude faster than previous NeRF-based algorithms. Such on-board capabilities are critical to enable downstream machine intelligence tasks necessary for autonomous guidance, navigation, and control tasks.

Contemporary Contested Ethiopian Media Practice and Its Influence on Journalists’ Autonomy and Role

ABSTRACT This study explores contemporary journalists’ autonomy and role in the Ethiopian contested media practice by taking journalists working in Amhara Media Corporation (AMC). A qualitative research approach was used to collect data from journalists and admin staff. For triangulation, this study combined document analysis and observation. Fourteen in-depth interviews were conducted with purposively selected journalists and admin staff. The interviews used semi-structured and open-ended questions that would allow journalists to reflect their perspectives freely. The study applied the Hierarchy of Influences Model to examine the data and support discussion. The findings of this study clearly signify that partisanship among journalists, the politicization of journalism, and flip-flop media practices prevail. The outsourced programs are used as a tool for silencing journalists from working independently. The journalists’ safety anxiety is the grim reality at AMC. As a result, journalists’ professional content productions and autonomies specifically on political and sensitive issues were negotiated or interfered. It is therefore challenging to maintain complete professional autonomy in order to be impartial, unbiased, and independent while working as a journalist in Ethiopia. It is recommended that the regional and federal governments should allow media independence and journalists’ autonomy in the Ethiopian media industry.

The conceptualisation of morality in Judaism

This article dealt with the irony that confronts any investigation into the conceptualisation of morality in Judaism: much of contemporary scholarship promotes the Strong Dependence Theory where God is considered the prime source of morality − yet an empirical analysis of classical rabbinic literature indicates a leaning more towards the Weak Dependence Theory which considers human beings the source for morality. Somehow, scholarship seems to overlook this textual evidence. On the other hand, that same contemporary scholarship has no problem in accepting absolute and complete human autonomy in the area of Jewish religious law or Halacha. This study questioned why humans are comfortably accepted as the primary determinants of religious law but not of morality – and argued for a return to the original Weak Dependence Theory to maintain moral efficacy. It included an examination of an extreme historical test case for rabbinic morality concerning how the rabbinic world dealt internally with the moral implications of major rabbis who had fled the Holocaust.Intradisciplinary and/or interdisciplinary implications: While this literature study was conducted from an orthodox rabbinic perspective, it adopted a descriptive and evaluative methodology based on academic, rabbinic and historical sources.

The Role of Artificial Intelligence Application in Strategic Marketing Decision-Making Process

This review article examines artificial intelligence (AI)’s role in strategic marketing decision-making. The researchers interviewed experts with experience in decision-making and used Carrefour Iraq as a case study to identify themes on how humans use AI for better strategic marketing decision-making. The key themes in this review were factors such as big data, efficiency, quality, trust and limitations for prediction. The study has also looked into the marketing aspect of these themes within the scope of this research. The findings indicate that AI is recognized as a tool that may support humans in making strategic decisions in marketing. However, AI can technically make such decisions without human intervention; people do not want to give AI complete autonomy in decision-making. Furthermore, the result implies that rather than making decisions independently, AI is more frequently applied to enhance strategic decision-making. It suggests that Al aims to improve decision making-making rather than supplant people in daily life. In addition, the study makes the case that Al can assist humans in making better decisions by forecasting future scenarios that consider a particular action consequence.

Moving Matter: A methodology for material-led collaborations

Interdisciplinary movement artists and educators Rob Kitsos and Meagan Woods share the process behind Moving Matter: material-led collaborative choreographies, a research-creation project that offers a methodology for rethinking the dynamism between raw materials, garments, and the body. Moving Matter steers the locus of choreography and wearable design away from human hierarchy to instead support truer collaboration amongst all moving materials, both human and non-human. In a challenge to normative structures where costumery operates ‘in service’ of dance, the textile designs for Moving Matter do not support the complete autonomy and freedom of moving humans; the wearables have striking characteristics of their own that limit what the human body can do. In establishing parameters, we intend not to reverse the hegemony of human-led design to human-suppressed design, but to re-recognize the agency of all matter through material-led collaborations that support distributed power and collective, innovative approaches to making. This paper details the artists’ studio process and their methodology template for material-led collaborative process that can be adapted for practices within and beyond performance and art disciplines.

Nutrition care for the adult post-intestinal transplant patient.

Intestinal transplantation has emerged as an accepted treatment choice for individuals experiencing irreversible intestinal failure. This treatment is particularly relevant for those who are not candidates or have poor response to autologous gut reconstruction or trophic hormone therapy, and who can no longer be sustained on parenteral nutrition. One of the main goals of transplant is to eliminate the need for parenteral support and its associated complications, while safely restoring complete nutrition autonomy. An intestinal transplant is a complex process that goes beyond merely replacing the intestines to provide nourishment and ceasing parenteral support. It requires an integrated management approach in the pretransplant and posttransplant setting, and high-quality nutrition treatment is one of the cornerstones leading to favorable outcomes and long-term management. Since the outset of intestinal transplant in the early 2000s, there is observed improvement of achieving nutrition autonomy sooner in the initial posttransplant phase; however, the development of nutrition complications in the chronic posttransplant period remains a long-term risk. This review delineates the decision-making process and clinical protocols used to nutritionally manage and monitor pre- and post-intestine transplant patients.

Mysterious informative control "from above", trite selection or permanent self-organization of living matter?

How much long the human civilization exists on Earth, so much time there are practically continuous disputes between supporters of creationism and evolutionism. At that in corresponding arguments, the former usually emphasize the astonishing complexity of live systems what's deliberately thereby associated with a pretty far-fetched chance of their self-emergence. While the latter flaunt about own totally unbiased reasoning which doesn’t require introduction of additional entities.Insofar as, to a certain extent, both of them prove to be right, so having analyzed all the scientific information at our disposal, we decided that it would be correct to try anyway to combine these, at first gaze, opposite ideas into a single whole. Thus, if to resume here the most important cornerstone points on which the author relies, justifying his view over organismic evolution, then one should indicate as follows.• Conceptually quite valid possibility of significant outwardly visible changes at the level of an individual – along with a strict karyotypic constancy in all its foreseeable ancestors. • The dominant role of the factors of internal self-development and selection as the main driving arms of progress.• The complete autonomy of the above evolutionary postulates from blind mutational entropy, i.e. the obvious independence of these routes from each other.In this way, the bold original theory presented in given article is based, by and large, just on those "three pillars".
