Protocol as Prescription: Governance Gaps in Automated Medical Policy Drafting
Get PDFThis article examines how health policy texts drafted with large language models can detach legal responsibility from the formal circuit of governance. Treating “protocol” as regla compilada, anchored to a Type 0 production in the Chomsky hierarchy, it specifies a provenance standard that binds each clause of an issued policy to its generating inputs, including prompts, parameters, retrieval sources, reviewers, timestamps, and cryptographic hashes. The method combines version-controlled diffs across scoping, drafting, legal review, and publication with a formal alignment of authority bearing constructions, focusing on deontic stacks, default scopes, agent deletion, and nominalizations. A simulated ministry case demonstrates end to end traceability, producing an exportable evidence bundle that links surviving clauses to their inputs and human approvals. Findings show where machine introduced formulations change duty of care or obscure decision rights, and define mandatory human sign offs when high risk constructions appear. The article delivers three operational artifacts for health agencies, a provenance specification, a responsibility matrix across drafting stages, and an audit checklist calibrated to inspection and courtroom needs. By reattaching authorship and justification to the formal record, the blueprint closes a governance gap in automated policy drafting and states the conditions under which AI assisted procedures remain defensible.

Personalized design and reconstruction for the defect bone based on data driving and mechanics modelling
No full textHuman periarticular bone defect is a difficult disease in orthopedics. There is challenge issue to recognize anisotropy, heterogeneity of bone tissue structure and graphics by low resolution clinic-CT image. In collaboration with clinical medicine, the data-driven and mechanics modeling technique for bone defect reconstruction is proposed. Data driven micro-CT and clinical-CT images are used to obtain the characteristics of cancellous bone structure and graphics. The experimental technology and numerical method are developed for predicting the mechanics parameters of animal specimen on the multi-axial stress state. The constitutive model of heterogeneous anisotropy of bone tissue is established and the parameters are deduced by Bayesian inference using the data given by numerical simulation and experiment. For designing the robust cancellous prosthesis bone, a kind of spinodal lattice is designed with random, indeterminate, aperiodic, asymmetry, irregular, large space for mechanical and biological function. The digital triplets with physical scanning CT image, virtual equivalent modulus and additive manufacturing lattice design are created to guide the clinical treatment of personalized bone defects. This work has been demonstrated in some clinical applications to the benefit of patients
High-demand industrial applications with thermochemically recycled carbon fiber
No full textThe use of carbon fiber (CF) has increased in the last decade, shifting from the aeronautical sector to the leisure and automotive sectors. CF production requires high energy consumption and emits large amounts of CO2. This increase in consumption generates a greater amount of CF composite waste, which must be properly managed to give it a second life. Deremco project aims to transfer and increase the TRL of different recycling technologies for composite from the wind and aeronautical sectors. The companies IDEC, BIRZIPLASTIK, and TECNALIA have focused on the recovery of post-production waste from the aeronautical sector to obtain recycled CF (rCF) through a thermochemical process. IDEC proposed the horizontal stabilizer of an aircraft's as a use case. This secondary structure requires a lower level of mechanical properties, so the introduction of rCF has proven feasible. BIRZIPLASTIK proposes developing a thermoplastic formulation with high technical requirements for automotive applications. Two formulations have been developed that meet these requirements, one of which is 100% recycled material. To carry out these success use cases, TECNALIA has worked on optimized the rCF sizing processes and integrating it into the compounding and Resin Transfer Molding (RTM) processes
Effect of Silt and Clay Contents in Natural Sand on the Compressive and Flexural Strengths of Standard Grade Concrete
No full textNatural river sand is often contaminated with varying quantities of silt, clay, and other organic impurities that adversely affect the quality of concrete. This research investigates the effects of silt and clay content on the compressive and flexural strengths of standard grade concrete. Sand samples were purposively collected from three locations, Site A, B, and C, while a control sample with slight impurities was obtained from Site D. Concrete cubes and beams using the same cement, coarse aggregate, and water ratios were tested at 14 and 28 days. The control sample obtained a compressive strength of 24.89 MPa, while the samples with 3, 4, 5, and 6 silt and clay attained 21.63, 17.18, 17.07, and 13.61 MPa, respectively. Flexural strengths follow a similar pattern, with only the control sample satisfying the minimum standard requirements. Results showed that increasing the silt and clay content decreases the compressive and flexural strengths. Hence, proper testing and washing to remove contaminated fine aggregates is strongly recommended prior to use in construction
Innovación y Gobernanza para un Agroturismo Rural Sostenible: Claves para la Resiliencia Territorial
Get PDFEl presente estudio examina la importancia de la innovación y la gobernanza como ejes estratégicos para consolidar un agroturismo rural sostenible y aportar a la resiliencia territorial. El objetivo central consistió en determinar cómo estas dimensiones inciden en la diversificación económica, la competitividad local y la cohesión social. La investigación se sustentó en una revisión documental de artículos científicos publicados entre 2020 y 2024, lo que permitió integrar aportes recientes vinculados con la innovación tecnológica, la gobernanza inclusiva y la sostenibilidad en el marco del agroturismo. Los resultados ponen de manifiesto que la implementación de tecnologías, acompañada de modelos de gobernanza participativa, promueve la conformación de redes colaborativas transparentes, optimiza la gestión de los recursos y fortalece los procesos de decisión colectiva. De igual forma, se observa que la innovación aplicada al agroturismo favorece la diversificación productiva, además de resguardar el patrimonio cultural y ambiental de los territorios. No obstante, persisten retos asociados a la apropiación tecnológica por parte de las comunidades rurales y su traducción en prácticas efectivas de gobernanza. Estas limitaciones abren la posibilidad de nuevas investigaciones encaminadas a explorar los alcances y restricciones de la integración entre innovación, gobernanza y resiliencia territorial en contextos de agroturismo
