Abstract	Geraniaceae seeds represent a role model in soft robotics thanks to their ability to move autonomously across and into the soil driven by humidity changes. The secret behind their mobility and adaptivity is embodied in the hierarchical structures and anatomical features of the biological hygroscopic tissues, geometrically designed to be selectively responsive to environmental humidity. Following a bioinspired approach, the internal structure and biomechanics of Pelargonium appendiculatum (L.f.) Willd seeds are investigated to develop a model for the design of a soft robot. The authors exploit the re-shaping ability of 4D printed materials to fabricate a seed-like soft robot, according to the natural specifications and model, and using biodegradable and hygroscopic polymers. The robot mimics the movement and performances of the natural seed, reaching a torque value of ≈30 µN m, an extensional force of ≈2.5 mN and it is capable to lift ≈100 times its own weight. Driven by environmental humidity changes, the artificial seed is able to explore a sample soil, adapting its morphology to interact with soil roughness and cracks.

Abstract	Traditional agricultural landscapes provide cultural ecosystem services to human communities. However, the limited profitability of these landscapes often discourages farmers from preserving them. The current research evaluates: (i) whether the market would reward farmers providing a cultural ecosystem service, through an increased willingness to pay (WTP), for a food product with a traditional agricultural landscape certification; and (ii) what happens to the WTP when a food product reports multiple certifications, including the traditional agricultural landscape one. A convenience sample of Italian extra-virgin olive oil (EVOO) buyers was involved in a non-hypothetical random nth price auction to determine the WTP for 250 ml EVOO bottles carrying different certification bundles. These bundles were composed of different combinations of three certifications: Organic, Protected Designation of Origin, and a traditional agricultural landscape certification associated with the preservation of terraced olive groves. The findings indicate that the traditional agricultural landscape certification receives a premium price both when EVOO carries it individually or combined with other labels. In the latter case, results show sub-additivity of premium prices. The current research proves that traditional agricultural landscapes are not necessarily bound to market failure; however, costs faced by farmers to maintain them can be rewarded through the market.

Abstract	Nowadays, energy-related issues are of paramount importance. Every energy transformation process results in the production of waste heat that can be harvested and reused, representing an ecological and economic opportunity. Waste heat to power (WHP) is the process of converting the waste heat into electricity. A novel approach is proposed based on the employment of liquid nano colloids. In this work, the triboelectric characterization of TiO

Abstract	Although the different alternative food networks (AFNs) have experienced increases worldwide for the last thirty years, they are still unable to provide an alternative capable of spreading on a large scale. They in fact remain niche experiments due to some limitations on their structure and governance. Thus, this study proposes and applies a design method to build a new sustainable food supply chain model capable of realizing a "jumping scale". Based on the theoretical and value framework of the Civil Economy (CE), the Economy for the Common Good (ECG), and the Development on a Human Scale (H-SD), the proposed design model aims to satisfy the needs of all stakeholders in the supply chain. Max-Neef's Needs Matrix and Design Thinking (DT) tools were used to develop the design model. Applying the design method to the food chain has allowed us to develop the concept of the "Food Village", an innovative food supply network far from the current economic mechanisms and based on the community and eco-sustainability.

Abstract	Plants have evolved different mechanisms to disperse from parent plants and improve germination to sustain their survival. The study of seed dispersal mechanisms, with the related structural and functional characteristics, is an active research topic for ecology, plant diversity, climate change, as well as for its relevance for material science and engineering. The natural mechanisms of seed dispersal show a rich source of robust, highly adaptive, mass and energy efficient mechanisms for optimized passive flying, landing, crawling and drilling. The secret of seeds mobility is embodied in the structural features and anatomical characteristics of their tissues, which are designed to be selectively responsive to changes in the environmental conditions, and which make seeds one of the most fascinating examples of morphological computation in Nature. Particularly clever for their spatial mobility performance, are those seeds that use their morphology and structural characteristics to be carried by the wind and dispersed over great distances (i.e. "winged" and "parachute" seeds), and seeds able to move and penetrate in soil with a self-burial mechanism driven by their hygromorphic properties and morphological features. By looking at their motion mechanisms, new design principles can be extracted and used as inspiration for smart artificial systems endowed with embodied intelligence. This mini-review systematically collects, for the first time together, the morphological, structural, biomechanical and aerodynamic information from selected plant seeds relevant to take inspiration for engineering design of soft robots, and discusses potential future developments in the field across material science, plant biology, robotics and embodied intelligence.

Abstract	Livestock activity is one of the most contributors to climate-change emissions in the agriculture sector. European environmental policies face with the challenge of increasing farmers economic gain not conflicting with environmental aim at the same time, to meet targets for reducing greenhouse gas emissions (GHG). The paper aims to contribute to the discussion on CO2 emission mitigation by providing efficiency performance measures in the presence of joint production of milk and GHG emissions.A Slacks-Based Measure-Data Envelopment Analysis (SBM-DEA) with undesirable output was adopted and integrated with Life Cycle Analysis (LCA) results from 10 dairy cattle farms in Umbria (Italy) to estimate their environmental efficiency and emission reduction potential. In addition, the dual model of the SBM-DEA was used to quantify the marginal CO2 reduction costs. Four farms resulted in no CO2-eq emission efficient, with a reduction potential ranging from 45.7% to 26.3% of CO2-eq. An average abatement cost of € 243.08 in terms of lower milk production per ton of CO2-eq reduced, was estimated for the whole sample. A positive relationship between marginal abatement costs and CO2-eq efficiency scores was estimated. Marginal abatement costs knowledge could allow assessing the economic impacts of different farms strategies aimed at reducing polluting emissions, as well as the introduction of incentive mechanisms by public decision makers.

Abstract	In the last few decades, the interest of consumers towards sustainable agri-food products has been growing. This trend reflects changes in the consumption patterns, which have been deeply influenced by the increased sensitivity concerning social and environmental issues. In this sense, several studies, with different methodological approaches, have investigated consumers’ willingness to pay and its determinants for products with different sustainability labels. To systematise the obtained results, this paper offers a review of the studies that used experimental economics in studying consumer preferences for sustainable food and agricultural products. The 41 studies included in the review were selected on the basis of the pre-identified criterion according to the systematic review approach. Albeit discordant, the results show that a large share of consumers is willing to pay a premium price for products with eco-friendly and organic certifications. Animal welfare, ‘local’ production, or social certification appear to have a lower influence on consumer choice of purchasing. Additional information is able to modify consumer expectations and consequentially their willingness to pay, depending on the individual’s responsibility and awareness.

Abstract	Objectives: To determine the accuracy of nodal staging in patients with prostate cancer (PCa) when Methods: This prospective study was conducted at our institution between June 2016 and October 2020. It included 64 patients with localized PCa with at least a 5% possibility for lymph node involvement in the Memorial Sloan Kettering Cancer Center nomogram, suitable for surgical treatment. All patients underwent magnetic resonance imaging (MRI) with IL and were pathologically confirmed. The day before surgery, transrectal ultrasound-guided injection (TRUS) of Results: A total of 1,316 lymph nodes were excised, including 1,102 from the ePLND (83.7%) and 214 (16.3%) sentinel lymph nodes (SLN). 26 SLN were dissected outside the ePLND template. The final pathology demonstrated 46 (3.5%) lymph node metastasis, 31 (67.4%) in the SLNB and 15 (32.6%) in the non-SLN ePLND. At the patient level, 18 (28.1%) patients had pN1. With a mean follow-up of 33.1 months, 4/19 (21.1%) pN1 patients had undetectable PSA, and 3/19 (15.8%) had a PSA < 0.1 ng/mL. Lymph node dissection included 20.6 lymph nodes per patient (IQR 15-24.2), with 3.3 SLNB nodes per patient (IQR 2-4.2). PPV and NPV were 100 and 97.8%, respectively. Sensitivity and specificity were 94.4 and 100%, respectively. FN was 5.5% and FP was 4.3%. Diagnostic yields were 95.3% and the non-diagnostic rate was 4.7%. Conclusion: Radiotracer injection into the prostate IL offers promising results for staging purposes in cases in which ePLND is considered. Negative SLNB is a predictor of negative ePLND. Patients with a limited burden of nodal metastasis have a significant chance of remaining free of biochemical recurrence at mid-term follow-up.

Abstract	Beef cattle production is a widespread activity in Italy in the agricultural field and determines an important impact on environment and resources consumption. Carbon footprint evaluation is thus necessary to evaluate the contributions of the different stages and the possible improvements of the production chain. In this study, two typical Italian beef production systems, a conventional and an organic one are investigated in order to evaluate the greenhouse gas emissions from "cradle to gate farm" by a Life Cycle Assessment (LCA) approach; the carbon footprint (CF) per 1kg of live weight meat is calculated. The contributions from feed production, enteric fermentation, and manure management are taken into account, in order to compare the life cycle of the two productions; also the carbon balance in soil is evaluated, in order to verify the impact in a life cycle perspective. The results of CF calculation of the two farms show that organic system (24.62kgCO

Abstract	The impact of tumor focality on prostate cancer (PCa) prognosis has been addressed in several studies with conflicting results. Tumor foci from multifocal (MF) PCa can show highly heterogeneous molecular features. Our aim was to analyze the protein expression of PTEN, SPOP, SLC45A3, ETV1, ERG and the "triple hit" (ERG overexpression, PTEN plus SLC45A3 loss) in unifocal (UF) and MF PCa, to evaluate their value as prognostic markers according to focality, and the role of tumor heterogeneity in MF disease. PTEN, SPOP, SLC45A3, ETV1 and ERG immunohistochemical expression was evaluated in 185 PCa from 9 TMAs, 51 UF and 134 MF. In a subset of 69 MF cases, the dominant and secondary foci (DF and SF) were compared. Heterogeneity was considered when both tumor foci presented different expression patterns. Relationship with clinicopathological features was also analyzed. MF PCa was diagnosed in significantly younger patients when compared to UF ones (p = 0.007). ETV1 overexpression was associated with UF disease (p = 0.028). A shorter time to PSA recurrence was related to SLC45A3 wt expression in UF PCa (p = 0.052), and to SPOP expression loss (p = 0.043) or "triple hit" phenotype in MF PCa (p = 0.041). In MF cases, PTEN loss, SLC45A3 loss and "triple hit" phenotype were associated with the DF and had significant heterogeneity. In conclusion, our results indicate that UF and MF PCa have relevant and consistent molecular differences. The analysis of an immunohistochemical panel, composed by PTEN, SPOP, SLC45A3, ETV1 and ERG, could be useful to predict outcome in MF cases.
