This paper describes the design, implementation and validation of a new strategy for efficiently browsing large microscopical images (mega-images). A mega-image is constructed by registering a sequential set of microscopic fields of view, compressed and stored in hard disk using the JPEG2000 standard (J2K). Navigation is accelerated by fully exploiting J2K properties through the introduction of a cache strategy and an optimal delivering of quality information. Cache is introduced at the level of the spatial and resolution dimensions while optimal delivering is implemented on the organisation of minimal information units. Navigation with the conventional use of J2K results in extraction times of about 500 ms. We show that these strategies can improve navigation velocities up to a 30%, while we can efficiently represent high-quality and high-resolution colour images of microscopic specimens.

Introduction: The World Health Organization (WHO) has emphasized the importance of ensuring respectful and dignified childbirth experiences. However, many countries, including Rwanda, have documented negative experiences during childbirth. Identifying best practices can help uncover sustainable solutions for resource-limited settings rather than focusing solely on the challenges and negative aspects.

Objective: To report on the feasibility and outcomes of universal language promotion intervention (Talk With Me Baby [TWMB]) embedded within routine well-child care for children from birth to 3-years old.
Methods: Across 2 primary care clinics, 29 health care team members participated in a 12-month trial to deliver TWMB within well-child care visits. Feasibility was based on clinician feedback during the trial, clinician knowledge assessments, and clinic data.

Objective: This study aimed to describe the monitoring of treatment fidelity in a pragmatic pediatric rehabilitation trial using the National Institutes of Health Behavior Change Consortium framework, and to identify child and therapist factors that influence treatment fidelity.
Methods: Therapists (n = 28) were trained in the key ingredients (1-on-1, functional, goal-directed, motor learning intervention) and study protocol for a comparative effectiveness trial titled: A Comparison: High Intensity periodic vs. Every week therapy in children with cerebral palsy (ACHIEVE) for children ages 2 to 8 years with cerebral palsy.
Background: The COVID-19 pandemic exposed weaknesses in healthcare systems and disparities in healthcare access across sub-Saharan Africa (SSA). The insights of frontline healthcare professionals (HCPs), and healthcare researchers involved with the response to COVID in SSA are crucial to ensuring that health systems are optimally prepared for the next pandemic threat. Nonetheless, there is limited consensus as to what are the clinical and public health research priorities necessary to ensure that SSA is optimally prepared and responsive to future pandemics.

Organic materials are promising as battery electrodes due to their flexible design, low cost, and sustainability. Although high electrolyte concentrations are known to suppress organic cathode dissolution, the organic cathode solubility depends on the interplay between the electrode and electrolyte polarities, which remains unexplored. Here, we elucidate the delicate interplay of electrode and electrolyte polarities to achieve stable cycling of organic cathode.
