Heterogeneous and micro-structured materials have been the object of multiscale and homogenization techniques aimed at recognizing the elastic properties of the equivalent continuum. The proposed investigation deals with the mechanical characterization of the heterogeneous material structured metamaterials through analyzing the ultimate strength using the limit analysis of the Representative Volume Element (RVE). To get the desired material strength, a novel finite element formulation based on the derivation of self-equilibrated solutions through the finite elements devoted to calculating the lower bound theorem has been implemented together with the limit analysis in Melàn’s formulation.

The finite element formulation is based on discrete mapping of Volterra dislocations in the structure using isoparametric representation. Using standard finite element techniques, the linear operator V, which relates the self-equilibrated internal solicitation to displacement-like nodal parameters, has been built through finite element discretization of displacement and strain.

The proposed work presented an elastic homogenization of the mechanical properties of an elementary cell with a geometry known in the literature, the isotropic truss. The matrix of elastic constants was calculated by subjecting the RVE to numerical load tests, simulated with a commercial FEM calculation code. This step showed the dependence of the isotropy properties, verified with Zener theory, on the density of the RVE. The isotropy condition of the material is only achieved for certain section ratios between body-centered cubic (BCC) and face-centered cubic (FCC), neglecting flexural effects at the nodes. The density that satisfies Zener’s conditions represents the isotropic geomatics of the isotropic truss.

For the isotropic case, the VFEM procedure was used to evaluate the isotropy of the limit domain and was compared with the Mises–Schleicher limit domain. The evaluation of residual ductility and dissipation energy allowed a measurement parameter for the limit anisotropy to be defined. The novelty of the proposal consisted in the formulation of both the linearized and the nonlinear limit locus of the material; hence, it furnished the starting point for further limit analysis of the structures whose elementary volume has been described through the proposed approach.

With around 40% of global waste attributed to the built environment sector, architects play a significant role in how resources are consumed, produced and wasted. UK architectural educators have made good progress to embed climate emergency issues in design curricula but the challenges of resource use and waste, and the opportunities afforded by circular economy design principles are less well-considered. The purpose of this paper is to provide new insights on how to introduce circular design principles to early-stage architectural design students within university curricula.

The study described took an experimental approach to designing design project briefs across several interlinked studio design projects for 1st-year Architecture students. Structured as a case study, each section describes the project, learning objectives, teaching methods and project reflections informed by a qualitative assessment of student development, outputs and feedback gathered through a questionnaire and focus group.

Introducing circular design early is highly beneficial to the development of knowledge on sustainability issues, critical design thinking and creative solution generation. Examples of beneficial teaching approaches include building systems thinking, facilitating collaboration, supporting learning-through-making, using simple analogies and referencing best-practice examples.

This research builds on limited existing circular design literature for built environment fields and through practical insights fills a significant knowledge gap on ways to introduce a complex and dynamic topic such as the circular economy to early-stage architectural design students as they develop fundamental discipline-specific knowledge, skills and competences.

This study aims to develop a production-oriented approach for optimal mass-customisation of floor panel layouts in cross-laminated timber (CLT) buildings. The study enables meeting building clients’ unique floor plan requirements at an optimal cost and simultaneously enhances manufacturers’ profit by minimising material and manufacturing process waste.

The present research uses a hybrid approach consisting of field data collection, mathematical modelling, development of a Genetic Algorithm (GA) and scenario analysis. Field data includes engineered timber production information, design data and building code requirements. The study adopts the Flexible Demand Assignment (FDA) technique to formulate a mathematical model for optimising the design of mass timber buildings and employs GA to identify optimal production solutions. Scenario analysis is performed to validate model outputs.

The proposed model successfully determines the load-bearing wall placement and building spans and specifications of floor panels that result in optimal production efficiency and the desired architectural layout. The results indicate that buildings made of a single category of thickness of panels but customised in various lengths to suit building layout are the most profitable scenario for CLT manufacturers and are a cost-effective option for clients.

The originality of the present study lies in its mathematical and model-driven approach towards implementing mass customisation in multi-storey buildings. The proposed model has been developed and validated based on a comprehensive set of real-world data and constraints.

This study aims to improve detection efficiency of fluorescence biosensor or a graphene field-effect transistor biosensor. Graphene field-effect transistor biosensing and fluorescent biosensing were integrated and combined with magnetic nanoparticles to construct a multi-sensor integrated microfluidic biochip for detecting single-stranded DNA. Multi-sensor integrated biochip demonstrated higher detection reliability for a single target and could simultaneously detect different targets.

In this study, the authors integrated graphene field-effect transistor biosensing and fluorescent biosensing, combined with magnetic nanoparticles, to fabricate a multi-sensor integrated microfluidic biochip for the detection of single-stranded deoxyribonucleic acid (DNA). Graphene films synthesized through chemical vapor deposition were transferred onto a glass substrate featuring two indium tin oxide electrodes, thus establishing conductive channels for the graphene field-effect transistor. Using π-π stacking, 1-pyrenebutanoic acid succinimidyl ester was immobilized onto the graphene film to serve as a medium for anchoring the probe aptamer. The fluorophore-labeled target DNA subsequently underwent hybridization with the probe aptamer, thereby forming a fluorescence detection channel.

This paper presents a novel approach using three channels of light, electricity and magnetism for the detection of single-stranded DNA, accompanied by the design of a microfluidic detection platform integrating biosensor chips. Remarkably, the detection limit achieved is 10 pm, with an impressively low relative standard deviation of 1.007%.

By detecting target DNA, the photo-electro-magnetic multi-sensor graphene field-effect transistor biosensor not only enhances the reliability and efficiency of detection but also exhibits additional advantages such as compact size, affordability, portability and straightforward automation. Real-time display of detection outcomes on the host facilitates a deeper comprehension of biochemical reaction dynamics. Moreover, besides detecting the same target, the sensor can also identify diverse targets, primarily leveraging the penetrative and noninvasive nature of light.

This study aims to investigate the associations between emotional regulation strategies, self-compassion and adaptive functioning in families of children with neurodevelopmental disorders (NDD) in comparison to families with typically developing (TD) children.

This cross-sectional study used a comprehensive set of validated measures to assess emotional regulation strategies, self-compassion and adaptive functioning. The study cohort consisted of 116 parents; 58 parents of children with NDD and 58 parents of TD children. The mean age of the children was 6.40 years (SD = 1.82).

The findings indicate that higher self-compassion is associated with improved adaptive functioning, evidenced by reduced levels of internalizing (depression, anxiety, withdrawal, somatic complaints) and externalizing (aggressive behaviors) problems. Parents of children with NDD reported greater levels of depression, anxiety and withdrawal compared to parents of TD children. Parents of TD children used cognitive reappraisal more frequently and exhibited higher levels of self-compassion, whereas the use of expressive suppression was more prevalent among parents of children with NDD.

These findings highlight the need for family-centered and tailored interventions that promote self-compassion and adaptive emotional regulation strategies to reduce internalizing and externalizing problems among parents of children with NDD. By providing comprehensive psychological support and accessible community resources, parental ability to cope with stress may be improved, fostering adaptive functioning that benefits both parents and children with NDD.

This study introduces a novel perspective on the importance of self-compassion and emotional regulation strategies in protecting and improving the mental well-being of parents with neurodevelopmental disorder children. It provides valuable insights for targeted interventions in NDD families, focusing on reducing the risk of mental health deterioration while promoting emotional resilience.

The number of university students seeking mental health support is rapidly increasing. To provide additional psychological support to students accessing well-being services, this study aimed to pilot a mental health Web application (app) called Orpheus®.

Guided by student consultations, a multi-methods approach was adopted, including an examination of in-app data, chart reviews of routinely collected student information and interviews with mental health practitioners. Usage data were analysed descriptively. Changes in mental health outcomes were examined using means, standard deviations and reliable change indices for anxiety and depression scores. Inductive and deductive thematic analysis was conducted on qualitative data from staff interviews and student feedback.

A total of 26 students registered an account with 39 completed app visits. On 37 of the 39 (94.9%) occasions, students reported reductions in the intensity of unwanted negative emotions. Statistically significant reductions in the average pooled anxiety and depression scores were observed. Of the 15 students who completed pre- and post-routine outcome measures, between 20% and 60% showed reliable and meaningful symptom improvements. Students reported that the app was helpful and easy to set up and use, with no adverse events. Practitioners highlighted barriers and facilitators related to the technology features, situational contexts and individual differences.

Integrating Orpheus in real-world settings resulted in promising implementation processes, potential for future uptake and positive outcomes. However, ongoing research, staff training and app testing are needed to further improve the implementation processes for digital mental health interventions.

This study explores the pivotal relationship between humble leadership (HL) and flourishing-at-work (FAW) in the context of the information technology-enabled services (ITes) industry. Specifically, it explores the mediating role of psychological empowerment (PE) and the moderating influence of proactive personality (PP) in this dynamic interplay.

Data from a comprehensive survey of 342 full-time employees from information technology-enabled services (ITes) organizations in India were meticulously analyzed. Utilizing covariance-based structural equation modeling (CB-SEM) in IBM AMOS 21.0.

The results illuminate the positive impact of HL on PE, subsequently enhancing FAW among employees. Furthermore, PE was identified as a partial mediator in the relationship between HL and FAW. Intriguingly, this mediation process was found to be significantly stronger when employees exhibited a higher degree of proactive personality.

This research underscores the critical importance of cultivating humble leadership within organizations. The findings emphasize the potential of targeted training programs aimed at nurturing humble leadership qualities among managerial staff. By doing so, organizations can significantly contribute to the emotional, psychological and social well-being of their employees, ultimately fostering a state of FAW.

This research innovatively links the concepts of humble leadership and FAW within the specific context of the ITes industry. By integrating PE as a mediator and PP as a moderator, this study not only fills a critical gap in existing literature but also provides a robust framework for future research.

This study evaluates the implementation of circular economy (CE) design strategies in mass timber construction to identify knowledge gaps and define crucial future research areas for promoting CE design adoption in this field.

A two-stage systematic literature review (SLR) was conducted to, first, identify CE design strategies applicable to the construction industry and then investigate the current state of CE design research in mass timber construction.
