Purpose Future places for learning and working are digitally and physically integrated hybrid environments. The purpose of this paper is to analyse the co-creation process of the remote presence-based digital and physical co-working and co-learning place. The context is cross-cultural when Finnish space approach is applied and further developed in Namibia. Design/methodology/approach A qualitative case study is conducted of the Future Tech Lab (FT Lab) in the University of Namibia’s main campus. The case study of the FT Lab is about 200m2 space with three different zones in the University of Namibia’s main campus. The physical solution encourages collaboration and technical solutions interlink the place overseas by using the remote presence. The data are gathered by using document analysis, observations, participatory workshops and interviews including structured questionnaire. Findings The action design research approach is a functional framework to co-create hybrid environments in two ways. It helps to design digital and physical solutions as integrated entity. Additionally, it provides a tool to analyse decision-making processes as well as design initiatives, also from the cultural perspective. Both Finnish and Namibian cultures are normative and feminine, which helped the realisation of the project based on mutual trust. However, the differences in power distance were affecting the process fluency and decision-making processes. Research limitations/implications The findings indicate that the co-design of the hybrid-learning environment sets requirements for the physical solution such as surface materials for premises and retrofitting of technology, which need to be considered by co-creation from the shared vision to realisation of the space. The co-creation involves many stakeholders, and cultural differences have a different impact on various stages of the co-creation process. Originality/value The cultural context in the case study provides an interesting comparison between the Finnish and Namibian approach. The remote presence and its requirements provide new knowledge and guidelines for co-creation of hybrid environments.

A given problem in physics can be solved if it is well formulated. Well formulated means that it has a bijective correspondence to physical reality. Mass Gap Problem has no bijective correspondence with the physical reality and is that’s why not solvable mathematically. It can be solved physically by the formulation of the photon’s mass accordingly to the Planck-Einstein relation.

In this paper, we study noncommutative static spherically symmetric wormhole solutions in the context of modified Gauss–Bonnet gravity. We explore these solutions either by assuming a viable [Formula: see text] model to construct shape function or by specifying the shape function to deduce [Formula: see text] model. The energy conditions are discussed for both types of wormholes. In the first case, we find a physically acceptable wormhole solution threaded by normal matter for all values of radial coordinate [Formula: see text] while the second case gives physical solution only for large values of [Formula: see text].

Rigid unit modes are shown to be dynamic within the AlPO4-5 structure down to low temperatures where the static time-averaged structure cannot provide a true physical solution.

Multiple solutions exist in many experimental situations where several interfering amplitudes are summed to fit experimentally measured distributions, such as cross sections, mass spectra, and/or angular distributions. We show a few examples where multiple solutions are found, but only one solution is reported in publications. Since there is no standard rule for choosing one among the solutions as the physics one, we propose a simple rule that agrees with what has been adopted in previous literature: the solution corresponding to the minimal magnitudes of the amplitudes must be the physical solution. We suggest testing this rule in future analyses.
