New matrix formulas for structural optical design have been obtained from analysis of derivative of the system matrix in respect to construction parameters and movements of components. Functional parameters of the optical system become elements of the matrix, presenting working conditions of the optical system. Developed methodology of structural design multi-group zoom systems with unlimited number of components and with mechanical-electronic compensation is presented. Any optical system, such as the objective lens, reproduction system, or telescopic system, can be analyzed with this methodology. Kinematics of components pertaining to a full tract of the zoom system is determined for a discrete number of positions. Three examples of the structural design of complex zoom systems with five-components and high zooming ratio are provided.

Evidence suggests that integrated support, combining both natural and formal supports, is often essential for individuals with developmental disabilities to achieve their preferred quality of life. However, studies are limited on how to organize supports so that people with developmental disabilities and their families find a balance between formal and natural supports. Often, there are systemic and personal boundaries around the nature and extent of support that can be offered to persons with developmental disabilities through formal mechanisms, yet the value of natural supports in the lives of persons with developmental disabilities is often undervalued in society.

Purpose: As the scope of practice continues to evolve for pharmacists, professional abstinence is being observed by students in workplaces and practicums. Professional abstinence is defined as "consciously choosing not to provide the full scope of patient care activities". Exposure of students to professional abstinence may cause cognitive dissonance, as they are challenged by practices that do not match what they are taught in school.

This paper presents an automated method for solving the initial structure of compact, high-zoom-ratio mid-wave infrared (MWIR) zoom lenses. Using differential analysis, the focal length variation process of zoom lenses under paraxial conditions is investigated, and a model for the focal power distribution and relative motion of three movable lens groups is established. The particle swarm optimization (PSO) algorithm is introduced into the zooming process analysis, and a program is developed in MATLAB to solve for the initial structure.

Background: Africa's involvement in clinical trials remains very low. Although the crucial role of training initiatives in building clinical trial capacity in Africa has been documented, current efforts fall short as they lack alignment with local contexts. This study aimed to design, develop, implement, and evaluate an innovative clinical trial operations training program for Africa.

Background: Learning health systems (LHS) have the potential to use health data in real time through rapid and continuous cycles of data interrogation, implementing insights to practice, feedback, and practice change. However, there is a lack of an appropriately skilled interprofessional informatics workforce that can leverage knowledge to design innovative solutions. Therefore, there is a need to develop tailored professional development training in digital health, to foster skilled interprofessional learning communities in the health care workforce in Australia.
