General principles for designing stable highly symmetrical clusters are proposed. This approach takes advantage of both the extra stability of cage aromaticity and the good geometrical balance between the outer cage and the endohedral atom. The applicability of these design principles was confirmed by gas-phase experimental observations on group 14 element cages with endohedral Al's and also is illustrated by many literature examples of diverse systems.

Operationalisation of self-determination of persons with profound intellectual and multiple disabilities: A Delphi study.
J Intellect Dev Disabil
September 2023
Department of Tranzo, Tilburg School of Social and Behavioral Sciences, Tilburg University, Tilburg, The Netherlands.
Background: The high support needs of persons with profound intellectual and multiple disabilities hamper their possibilities for self-determination. To support their self-determination understanding of what this means for this group is necessary.
Method: A three-round Delphi procedure with international experts was undertaken to operationalise self-determination for persons with profound intellectual and multiple disabilities.
How should we support families of people with intellectual disability to promote their self-determination? A Delphi study on critical components for intervention.

December 2023
University Institute of Family Studies, Comillas Pontifical University, Madrid, Spain.
Background And Aims: Self-determination related skills are central for achieving a life of quality for people with intellectual disability and develop as the person interacts with his/her contexts, such as home. As such, families are crucial agents in supporting the self-determination of their children with intellectual disability, although to date, little is known about how to support those families.
Methods: To address this need, the present study used a Delphi technique to build and reach a consensus on the critical components that should inform interventions targeting families to promote their children's self-determination.
Low-temperature phase (β-form) barium borate (BBO) is one of the most important nonlinear crystals that has been widely used for optical second-harmonic generation (SHG), especially with femtosecond sources. There was growing interest in its applications in the direct generation of terahertz (THz) radiations, but it was hindered by the lack of knowledge of its basic properties in the THz range. In a recent study based on first-principles quantum chemistry calculation, we found that the theoretically calculated refractive indices of β-BBO in the THz frequency range do not agree with the previously reported values.

Here, we demonstrate the single-mode of two-dimensional transverse magnetic (TM) Dirac-vortex topological cavity modes that are not only generally available for high power topological surface-emitting lasers (TCSEL) but also are one of the excellent candidates for refractive index sensors. The principle for winding number is studied, and the scaling laws are shown with cavity mode diameters.

Research progress and innovation are hindered by barriers, inequalities, and exclusions within academia. Embracing equality, diversity, and inclusion (EDI) is not only an ethical imperative but also essential for advancing knowledge and addressing global challenges. EDI principles ensure that researchers from all backgrounds have equitable opportunities to contribute to and benefit from research.
