This paper describes a functional evaluation test of a fabric-based hand exoskeleton for various grasp taxonomies. We conducted an adapted version of the Jebsen Taylor Hand Function Test (JTHFT) with a healthy subject. The evaluation investigates a comparison of the times it takes the user to perform the task with and without the device, establishi...
Currently, many useful robotic devices have been used in daily therapeutic life. These assistive and social robots are widely explored in different areas and scenarios, which have allowed physical or cognitive interaction with patients. Likewise, social robots have been recently implemented as a tool to improve the procedure’s quality and support p...
Brain–Computer Interfaces (BCI) are emerging tools that integrate the central nervous system in the rehabilitation process to empower recovery. Technologies based on EEG signals acquisition seem to present an enormous potential complementing existing therapies with exoskeletons and improving both neurological patients’ mobility and neuroplasticity....
This article shows the design, development, implementation, and control software associated with a hand exoskeleton capable of assisting in basic actions, such as opening and closing. Robotic architectures, geometric and kinematic analysis are reviewed, obtaining a proprietary design based on the biometrics of Chilean individuals. The exoskeleton m...
This work presents the development and implementation of an interface to control a robotic exoskeleton for gait rehabilitation in patients with stroke through exercises based on conventional neuro-rehabilitation therapies. Movement patterns of each exercise were acquired using an optoelectronic ten-camera system in a group of subjects without patho...
The technological transfer between the areas of computer engineering and health have allowed collaborative work and effective support between both areas. This is how the development of robotics in the present can aid in repetitive activities or activities that present a lesser degree of direct intervention with the patient in certain therapies. Thi...
The issue of ‘predatory publishing’, and indeed unscholarly publishing practices, affects all academics and librarians around the globe. However, there are some flaws in arguments and analyses made in several papers published on this topic, in particular those that have relied heavily on the blacklists that were established by Jeffrey Beall. While...
Caracterizar las estrategias de movilidad de las sociedades cazadoras-recolectoras-pescadoras en ambientes insulares y litorales es fundamental para comprender la interacción humano-ambiental en el pasado. Las prospecciones en el noreste de la isla Diego Portales, en el mar interior de Última Esperanza (Magallanes, Chile), han permitido documentar...
The causes underlying Holocene glacier fluctuations remain elusive, despite decades of research efforts. Cosmogenic nuclide dating has allowed systematic study and thus improved knowledge of glacier-climate dynamics during this time frame, in part by filling in geographical gaps in both hemispheres. Here we present a new comprehensive Holocene mora...
DC–DC power converters have generated much interest, as they can be used in a wide range of applications. In micro-inverter applications, flyback topologies are a relevant research topic due to their efficiency and simplicity. On the other hand, solar photovoltaic (PV) systems are one of the fastest growing and most promising renewable energy sourc...
La teoría y la investigación sobre el apego se utilizan en muchos contextos aplicados, incluidos los juzgados de familia, pero hay malentendidos muy extendidos y que a veces dan lugar a aplicaciones erróneas. El objetivo de este documento de consenso es, por lo tanto, mejorar la comprensión, contrarrestar la desinformación y dirigir el uso de la te...
Armoured dinosaurs are well known for their evolution of specialized tail weapons—paired tail spikes in stegosaurs and heavy tail clubs in advanced ankylosaurs1. Armoured dinosaurs from southern Gondwana are rare and enigmatic, but probably include the earliest branches of Ankylosauria2–4. Here we describe a mostly complete, semi-articulated skelet...
Emergent evidence indicates that the carotid body (CB) chemoreceptors may sense systemic inflammatory molecules, and is an afferent-arm of the anti-inflammatory reflex. Moreover, a pro-inflammatory milieu within the CB is involved in the enhanced CB chemosensory responsiveness to oxygen following sustained and intermittent hypoxia. In this review,...
Background
Butanol is a versatile chemical that can be used as fuel, solvent or intermediate in chemical synthesis. Several strategies have been used to increase the availability of reducing power in Clostridium sp. with the aim of maximizing the production of butanol, being the use of electron carriers one of the most effective. Moreover, electron...
One of the most severe environmental issues affecting the sustainable growth of human society is water pollution. Phenolic compounds are toxic, hazardous and carcinogenic to humans and animals even at low concentrations. Thus, it is compulsory to remove the compounds from polluted wastewater before being discharged into the ecosystem. Biotechnology...
Since the heroic age of Antarctic exploration, the continent has been pressurized by multiple anthropogenic activities, today including research and tourism, which have led to the emergence of phenol pollution. Natural attenuation rates are very slow in this region due to the harsh environmental conditions; hence, biodegradation of phenol using nat...
Community assembly is the result of both, deterministic and stochastic processes. The former encompasses niche-based local-scale mechanisms such as environmental filtering and biotic interactions; the latter includes ecological drift, probabilistic colonisation, and random extinctions. Using standardised sampling protocols, we show that the spatial...
The European aquaculture industry began to undertake Atlantic halibut (Hippoglossus hippoglossus) aquaculture in the 1980s due to the favorable growth rate and high market value of this cold-water marine fish. Atlantic halibut cultivation began in Chile in 1996 in the Magallanes region (53˚S). Chilean aquaculture facilities were finally equipped to...
Aim
We investigated evolutionary relationships and biogeographical patterns within the genus Boeckella to evaluate (1) whether its current widespread distribution in the Southern Hemisphere is due to recent long-distance dispersal or long-term diversification; and (2) the age and origin of sub-Antarctic and Antarctic Boeckella species, with particu...
Background
Deep breathing (DB) and handgrip (HG) exercise -with and without circulatory occlusion (OC) in muscle-, have been shown to have beneficial effects on cardiovascular function; however, the combination of these maneuvers on heart rate (HR) and cardiac sympathovagal balance have not been previously investigated. Therefore, the aim of the pr...
