Superhydrophobic SLA 3D printed materials modified with nanoparticles biomimicking the hierarchical structure of a rice leaf
Autor: Belén Barraza, Felipe Olate-Moya, Gino Montecinos, Jaime H. Ortega, Andreas Rosenkranz, Aldo Tamburrino, Humberto Palza
Publikováno v: Science and Technology of Advanced Materials, Vol 23, Iss 1, Pp 300-321 (2022)
The rice leaf, combining the surface properties of lotus leaves and shark skin, presents outstanding superhydrophobic properties motivating its biomimesis. We created a novel biomimetic rice-leaf superhydrophobic surface by a three-level hierarchical

Modeling of Brain Shift Phenomenon for Different Craniotomies and Solid Models
Autor: Alvaro Valencia, Benjamin Blas, Jaime H. Ortega
Publikováno v: Journal of Applied Mathematics, Vol 2012 (2012)
This study investigates the effects of different solid models on predictions of brain shift for three craniotomies. We created a generic 3D brain model based on healthy human brain and modeled the brain parenchyma as single continuum and constrained

Discrete Calderón problem with partial data
Autor: Jaime H. Ortega, Rodrigo Lecaros, Luz De Teresa, Ariel Pérez
Publikováno v: Inverse Problems. 39:035001
In this work, we are interested in analyzing the well-known Calderón problem, which is an inverse boundary value problem of determining a coefficient function of an elliptic partial differential equation from the knowledge of the associated Dirichle

We study the problem of source reconstruction for a linear elasticity problem applied to seismicity induced by mining. We assume the source is written as a variable separable function $\mathbf{f(x)}\>g(t)$ . We first present a simple proof a local de

Perturbative corrections for the scaling of heat transport in a Hele-Shaw geometry and its application to geological vertical fractures
Autor: Jaime H. Ortega, Juvenal A. Letelier, Nicolás Mujica
Publikováno v: Journal of Fluid Mechanics. 864:746-767
In this work, we investigate numerically the perturbative effects of cell aperture in heat transport and thermal dissipation rate for a vertical Hele-Shaw geometry, which is used as an analogue representation of a planar vertical fracture at the labo

The type III secretion systems (T3SS) encoded in pathogenicity islands SPI-1 and SPI-2 are key virulence factors of Salmonella. These systems translocate proteins known as effectors into eukaryotic cells during infection. To characterize the function

The stability for an inverse problem of bottom recovering in water-waves
Autor: Rodrigo Lecaros, Jaime H. Ortega, Sebastián Zamorano, J. López-Ríos
In this article we deal with a class of geometric inverse problem for bottom detection by one single measurement on the free surface in water--waves. We found upper and lower bounds for the size of the region enclosed between two different bottoms, i

Bottom Detection Through Surface Measurements on Water Waves
Autor: J. C. López Ríos, Jaime H. Ortega, Marco A. Fontelos, Rodrigo Lecaros
Publikováno v: SIAM Journal on Control and Optimization. 55:3890-3907
The direct problem of water-wave equations is the problem of determining the surface and its velocity potential, in time $T>0$, for a given initial profile and velocity potential, where the profile...
