High- fi delity non-adiabatic cutting and stitching of a spin chain via local control
(IOP Publishing, 2018-10-18)
We propose and analyze, focusing on non-adiabatic effects, a technique of manipulating quantum spin systems based on local 'cutting' and 'stitching' of the Heisenberg exchange coupling between the spins. This first operation ...
A new index of semantic short-term memory: Development and validation of the conceptual span task in Spanish
(Public Library Science, 2018-12-27)
Mounting evidence from both cognitive and neuropsychological research points to the importance of conceptual and lexical-semantic contributors to short-term memory performance. Nonetheless, a standardized and well-controlled ...
The metabolic regimes of 356 rivers in the United States
(Nature Publishing, 2018-12-11)
A national-scale quantification of metabolic energy flow in streams and rivers can improve understanding of the temporal dynamics of in-stream activity, links between energy cycling and ecosystem services, and the effects ...
Hesperidin and Capsaicin, But Not The Combination, Prevent Hepatic Steatosis and Other Metabolic Syndrome-Related Alterations in Western Diet-Fed Rats
(Nature Publishing Group, 2018-10-10)
We aimed to assess the potential effects of hesperidin and capsaicin, independently and in combination, to prevent the development of obesity and its related metabolic alterations in rats fed an obesogenic diet. Three-month-old ...
Influence of PLA Filament Conditions on Characteristics of FDM Parts
(MDPI, 2018-08)
Additive manufacturing technologies play an important role in Industry 4.0. One of the most prevalent processes is fused deposition modelling (FDM) due to its versatility and low cost. However, there is still a lack of ...
Airbnb Branding: Heritage as a Branding Element in the Sharing Economy
(MDPI, 2018-12-23)
The cultural heritage of cities has been proven to be a generator of economic activity and a singular place branding/marketing tool for territories. In addition, in recent times, there has been a boom in the collaborative ...
La estatalidad del deporte internacional. Pasado, presente, ¿futuro?
(El Colegio de México, 2018-06)
La organización y expansión del deporte internacional durante el siglo XX se ancló principalmente a la implicación político-económica de los Estados, motivada por su representación en las competiciones deportivas por ...
Spinal cord injury induces astroglial conversion towards neuronal lineage
(Biomed Central, 2016-10-06)
Background: Neurons have intrinsic capability to regenerate after lesion, though not spontaneously. Spinal cord injury (SCI) causes permanent neurological impairments partly due to formation of a glial scar that is composed ...
Mechatronic modeling of a parallel kinematics multi-axial simulation table based on decoupling the actuators and manipulator dynamics
(Elsevier, 2016-11-07)
In this work a mechatronic model was developed for a parallel Multi-Axial Simulation Table (MAST) mechanism. The dynamics of the mechanism was obtained using the principle of energy equivalence and Boltzmann–Hamel equations. ...
Mechatronics of a ball screw drive using a N degrees of freedom dynamic model
(Springer, 2017-10)
High performance position control in machine tools can only be achieved modelling the dynamic behavior of the mechatronic system composed by the motor, transmission and control during the design stage. In this work, a ...
