Upcycling Architecture in Italy since 1945
No full textWould it be possible to re-examine Italian architecture from 1945 onwards through the lens of Upcycling and Design for Disassembly - understanding these as design strategies for reusing existing materials while adding new value, and as critical alternatives to the relentless demand for producing new materials? This innovative volume identifies and analyses twentieth-century Italian architectural experiences that reveal the continuous adaptation of ancient design and building practices of reuse, which can be considered visionary precedents of today's upcycling trends. In doing so, it challenges the usual view of the twentieth century as the period when the construction industry abandoned millennia-old practices of architectural reuse in favor of a cradle-to-grave model. The essays and case studies featured in this book examine anachronisms, the endurance of ancient traditions, and pioneering design experiments in Italy and beyond. They uncover the roots, ambiguities, and potential of an architecture of upcycling, and provide a new historiographical, theoretical, and design framework for its understanding
Failure analysis of a woven composite under tension–compression very high cycle fatigue (VHCF)
No full textIn this work, the tension–compression response of a carbon fiber woven composite is investigated in the Very High Cycle Fatigue (VHCF) regime through axial ultrasonic testing. To enhance the stress-to-displacement ratio with respect to standard straight bars, hourglass-shaped specimen was proposed in a previous work, with, however, the failure influenced by shear stresses. To overcome this limitation, while maintaining high stress-to-displacement ratio, a straight-tabbed geometry is here proposed and tested. Several combinations of adhesives, tab materials and tab geometries are studied to identify a suitable configuration for ultrasonic testing. Results show comparable fatigue performance of the hourglass-shaped and tabbed specimens, with failure driven by stress concentrations at the tip of the tabbed region. Finite Element analyses of a microscale fiber–matrix model are performed to examine the multiaxial stress states in both geometries and evaluate the contribution of individual stress components to the matrix stress field
Recent Joining Materials Options for Ceramic Matrix Composites
Full text linkThe urgent need to mitigate climate change has driven the exploration of innovative materials and processes to achieve net-zero carbon emissions. This work investigates the potential of ceramic matrix composites (CMCs) as alternatives to traditional metals in high-temperature industrial applications, within the European Union project CEM-WAVE. Various joining materials, including glass-ceramics, metallic brazes, and pre-ceramic polymers, are evaluated for their effectiveness in creating robust CMC joints. The study demonstrates the viability of CMCs in steelmaking and other energy-intensive sectors, highlighting their resistance to extreme conditions and potential to replace metallic alloys. The findings underscore the need for continued research to optimize manufacturing processes and reduce costs, paving the way for broader adoption of CMCs in achieving sustainable industrial practices
Neck Dissection in the Era of Immunotherapy: A Narrative Review
No full textCervical lymph node metastases are major prognostic determinants in head and neck squamous cell carcinoma (HNSCC), and neck dissection (ND) has long been central to regional control. As ND has evolved from radical to selective procedures, immune checkpoint inhibitors (ICIs) have emerged as a fourth treatment pillar, reframing tumor-draining lymph nodes (TDLNs) as active immune organs rather than passive conduits of metastatic spread. This narrative review synthesizes surgical, immunologic, and translational evidence on how ND and cervical irradiation interact with immunotherapy. It also examines the historical development of ND, the immunologic structure and function of cervical TDLNs, and the use of neoadjuvant, perioperative, and recurrent/metastatic immunotherapy in HNSCC. Preclinical and early clinical observations suggest that ablating or heavily irradiating non-involved nodal basins may attenuate ICI efficacy by disrupting antigen presentation, progenitor exhausted CD8+ T (Tpex) cell pools, and effector recirculation, supporting the conceptual model of an “immune desert neck.” The review critically appraises timing (pre- versus post-immunotherapy ND), response-adapted or de-escalated surgery, and imaging, tissue-based, and circulating biomarkers to guide individualized management. Current evidence does not support abandoning elective or therapeutic ND, but does highlight the need for biomarker-driven, lymphatic-sparing trials to redefine when ND is essential, modifiable, or potentially avoidable in immunotherapy-treated HNSCC
Facile fabrication of a reusable MOF-808@3D-printed device for the efficient adsorptive removal of chloramphenicol from water
No full textA binder-free composite device was fabricated by immobilizing MOF-808 onto a stereolithographically 3Dprinted polymeric support, aiming to overcome handling and reusability limitations of powder MOFs in water
treatment. Structural and morphological characterizations confirmed that MOF-808 crystallinity and uniform
surface exposure were preserved after immobilization, while the printed architecture retained its macroporosity
and mechanical integrity. The resulting device exhibited excellent adsorption performance toward chloramphenicol in water, achieving a maximum adsorption capacity of approximately 47 mg⋅g− 1 and nearly complete
removal (≈98%) within 180 min. Adsorption behavior was well described by a Langmuir monolayer model and
pseudo-second-order kinetics, indicating a surface-controlled process governed by specific interactions between
the pollutant and MOF-808 active sites. Intraparticle diffusion analysis revealed a multistep transport mechanism
dominated by boundary-layer diffusion, with intraparticle transport playing a secondary role, consistent with the
external localization of MOF-808 particles on the 3D scaffold. The composite demonstrated high stability and
reusability, retaining over 90% of its adsorption efficiency after five cycles and maintaining more than 80%
removal in real tap water. Preliminary column modeling based on kinetic parameters further suggested long
breakthrough times under realistic operating conditions, highlighting the scalability of the MOF-808@3Dprinted device for continuous water treatment applications
Geometrically constrained walls in three dimensions
No full textWe study geometrically constrained magnetic walls in a three dimensional geometry where two bulks are connected by a thin neck. Without imposing any symmetry assumption on the domain, we investigate the scaling of the energy as the size of the neck vanishes. We identify five significant scaling regimes, for all of which we characterise the energy scaling and identify the asymptotic behaviour of the domain wall. Finally, we notice the emergence of sub-regimes that are not present in the previous works due to restrictive symmetry assumptions
RCbench: a unified framework for benchmarking reservoir computing systems
No full textReservoir computing (RC) is a computational framework where a fixed dynamical reservoir projects an input into a higher-dimensional state that is then analyzed by a readout, which is trained to map the reservoir state into the desired output. While the conventional RC paradigm is based on dynamics of in-silico implemented recurrent neural networks, this computing paradigm can be efficiently implemented in hardware by exploiting dynamics of a wide range of physical systems in a paradigm denoted as Physical RC (PRC), attracting interest from a broader research community spanning from computer scientists to physicists, and material scientists. Here, we present RCbench, an open-source RC benchmark toolkit that implements a standardized and comprehensive suite for benchmarking computational reservoir models and physical implementations of RC. RCbench integrates widely recognized metrics such as Memory capacity, Nonlinear autoregressive moving average of order N, Kernel rank , and generalization rank, along with nonlinear transformation tasks. It also allows testing and comparing different readout algorithms, the evaluation of computational capabilities with diverse accuracy metrics, and includes feature selection methods to unravel the effect of specific reservoir outputs on computational performances. In particular, the toolkit enables easy benchmarking of PRC systems, providing a comprehensive benchmark tool that can be easily integrated with experimental data acquisition processes. By standardizing performance assessments, RCbench aims to facilitate inter-study comparisons and to accelerate the exploration, characterization and optimization of RC systems

Il ruolo del Terzo Settore nei processi di rigenerazione urbana del quartiere ex industriale in Borgata Montebianco a Torino
No full textLa riqualificazione di aree urbane storicamente dedicate all'industria richiede una visione d'insieme che coordini interventi e politiche di accompagnamento che consentano un adattamento continuo alle mutevoli condizioni in lunghi periodi di attuazione.
Questo articolo esamina il potenziale del terzo settore come agente attivo nella valutazione dei processi di rigenerazione in corso. Lo studio si concentra sul quartiere Montebianco a Barriera Milano, Torino, un polo industriale di inizio Novecento che ha subito un'importante riqualificazione urbana negli ultimi due decenni. Grazie alla partnership tra il Politecnico di Torino e l'Associazione Barriera Design District, la ricerca coordina iniziative di valorizzazione urbana attraverso la valutazione continua delle proposte attive a supporto del processo decisionale. Adottando una prospettiva bottom-up, questo approccio introduce un metodo sperimentale basato su modelli ibridi di mappatura degli stakeholder e sul metodo di Analisi di Impatto Comunitario per avviare fasi di monitoraggio e valutare la pre-fattibilità, misurando infine gli impatti sia qualitativi che quantitativi sul territorio
Climate-adaptive prediction of wind erosion risks for earthen heritage under multi-scenario futures
No full textEarthen heritage sites are vital components of global cultural assets, yet face intensifying wind erosion driven by more frequent extreme wind events. Accurate erosion prediction is critical to preserve structural integrity and guide climate-adaptive management under UNESCO's climate action framework. However, current methods rely on simplified geometry models or limited wind simulations, producing insufficient spatial resolution and overlooking differential mass loss among components. Temporally, projections based on linear extrapolation from typical years neglect long-term, non-stationary trends. This study developed an integrated prediction framework combining centimeter-scale LiDAR modeling, high-resolution computational fluid dynamics (CFD), and CMIP6 multi-scenario climate data. Applied to the representative Chinese earthen heritage site Xixia Imperial Tombs, the framework produces site-wide risk maps and identifies localized high-risk zones. Results quantify nonlinear erosion responses to wind speed gradients, extending conventional initiation thresholds with acceleration inflection points. Temporal resampling refines wind-speed resolution, producing annual projections of cumulative erosion metrics (mass, depth, volume) through 2100 under SSP2-4.5 and SSP5-8.5 scenarios. The intermediate SSP2-4.5 pathway shows higher interannual variability and greater mean cumulative erosion than the high-forcing SSP5-8.5 scenario, indicating elevated long-term degradation risk under moderate climate forcing. Both scenarios displayed wide uncertainty ranges, suggesting a substantial likelihood of extreme erosion outcomes beyond mean projections. By integrating highprecision simulation with scenario-sensitive climate data, this framework advances predictive modeling of climate-driven hazards in the built environment and supports resilient planning and conservation of earthen heritage in arid regions
