SGSI support throught malware's classification using a pattern analysis
(IEEE, 2016)
Nowadays, there are significant amounts of malware codes that are created every day. However, the majority of these samples (malware) are variations of other malware that have been already identified. Therefore, most of ...
Real time optical flow estimation for images with large displacements
(2016 IEEE International Conference on Automatica (ICA-ACCA), 2016)
Optical flow is defined as the pattern of apparent motion of objects in a image sequence. Optical flow has many applications: control of automatic taking off and landing of an autonomous aircraft, video compression, noise ...
La conquista de la naturaleza: el imaginario arquitectónico de Alonso de Ovalle en el siglo XVII
(Pontificia Universidad Católica de Chile, Escuela de Arquitectura, 2016-12)
Como todo imaginario nacional, la idea de Chile como un lugar con una naturaleza salvaje y hostil ha sido construido desde los primeros relatos que describieron al país. Este texto argumenta que los grabados realizados por ...
Origin of axonal proteins: Is the axon-schwann cell unit a functional syncytium?
(CIENCIAS, 2016)
The structural homeostasis is challenging for neurons, whose axons extend up to meters in large animals, and the axoplasmic mass reaches over a thousand times that of the cell body. Thus, the protein demand may overcome ...
Schwann cell and axon: An interlaced unit—From action potential to phenotype expression
(Facultad de Ciencias, 2016)
Here we propose a model of a peripheral axon with a great deal of autonomy from its cell body-the autonomous axon-but with a substantial dependence on its ensheathing Schwann cell (SC), the axon-SC unit. We review evidence ...
Bursting the unfolded protein response accelerates axonal regeneration
(CIENCIAS, 2016)
Peripheral neuropathies refer to a group of conditions in which the peripheral nervous system (PNS) is damaged. These pathological state are are associated with weakness, pain, and loss of motor and sensory control. More ...
Injury to the nervous system: A look into the ER
(CIENCIAS, 2016)
Injury to the central or peripheral nervous systems leads to the loss of cognitive and/or sensorimotor capabilities that still lack an effective treatment. Although injury to the nervous system involves multiple and complex ...
Altered potassium channel distribution and composition in myelinated axons suppresses hyperexcitability following injury
(CIENCIAS, 2016)
Neuropathic pain following peripheral nerve injury is associated with hyperexcitability in damaged myelinated sensory axons, which begins to normalise over time. We investigated the composition and distribution of ...
