Designing a provider-led multimorbidity care model for fragmented insurance-based health systems: A mixed-methods study in Colombia

Omaira Valencia · Oscar Bernal

Multimorbidity the coexistence of two or more chronic conditions is a growing challenge for health systems in low- and middle-income countries (LMICs) structured around single-disease paradigms. In Colombia, insurer–provider fragmentation within the General System of Social Security in Health (SGSSS) compounds this cha...

A Sensing-Aware Simulation-Based Digital Twin Framework for Firmware-Level Validation of Photovoltaic MPPT Controllers

Carlos René Suárez Suárez · Yimy Edisson García Vera · Alfonso Durán Caicedo

As the photovoltaic (PV) generation sector expands, ensuring reliable maximum power point tracking (MPPT) in embedded controllers becomes increasingly important. However, many MPPT studies rely on idealized simulation assumptions that neglect practical sensing limitations, including ADC quantization, finite measurement...

Quantum states of three 3He atoms confined in a C60 fullerene

Pohl Moreno-Roncancio · Félix Moncada · Andrés Reyes

We employ a Non-Coulombic Non-Orthogonal Configuration Interaction (NC-NOCI) approach to study the confinement of three fermionic helium atoms, 3He, inside a C60 fullerene, with the aim of elucidating how encapsulation affects their spatial distribution and energy-level structure. To interpret the NC-NOCI results, we u...

Establishing a First-Feeding Protocol for the Larviculture of the Neotropical Catfish Pseudopimelodus atricaudus

Luis Alarcón-Martínez · Miguel Guzmán-Yance · César Montes-Petro · Carlos Tapia-Pacheco · y 3 más

The development of first-feeding protocols is a critical step in the domestication of native fish species for aquaculture. This study aimed to evaluate the first-feeding management of Pseudopimelodus atricaudus, a Neotropical catfish with aquaculture potential, using four prey types: Artemia nauplii (AN), decapsulated...
