The goal of the study was to quantify error prediction processes via neural correlates in the Electroencephalogram (EEG). Access to such a neural signal will allow to gain insights into functional and temporal aspects of error perception in the course of learning. We focused on the error negativity (Ne) or error-related negativity (ERN) as a candidate index for the prediction processes. We have...

The catalytic domains of most eukaryotic protein kinases are highly conserved in their primary structures. Their phosphorylation within the well-known activation T-loop, a variable region between protein kinase catalytic subdomains VII and VIII, is a common mechanism for stimulation of their phosphotransferase activities. Extracellular signal-regulated kinase 1 (ERK1), a member of the extensive...

BACKGROUND The throwing motion results in unilateral increases in dominant arm external rotation (ER) range of motion (ROM). Trunk forward tilt at ball release is related to ball velocity. The relationship between lower quarter flexibility and dominant arm ROM is not known. HYPOTHESIS There is a relationship between lower extremity flexibility and dominant arm ER ROM and total rotation ROM. ...

Most research on visual search in aiming at far targets assumes preprogrammed motor control implying that relevant visual information is detected prior to the final shooting or throwing movements. Eye movement data indirectly support this claim for stationary tasks. Using the basketball jump shot as experimental task we investigated whether in dynamic tasks in which the target can be seen until...

This project investigated the effect of incorporating 8 weeks biweekly upper limb loaded plyometric training (using elastic bands) into in-season regimen handball players. Participants were randomly allocated to a control group (CG) (n = 15, age 18.1 ± 0.5 years, body mass 73.7 13.9 kg), or an experimental (EG) 14, 17.7 0.3 76.8 10.7 kg). The measurements obtained pre- and post-intervention inc...

As illustrated in Chapter 3, open-loop stabilization of the bouncing ball requires negative acceleration of the actuator at impact (eq. (3.19), see Schaal et al., 1996). In contrast, the mirror law algorithms have been designed in closed-loop and can consequently afford positive acceleration at impact. The aim of this chapter is to discuss the role of acceleration tuning for robust closed-loop ...

the aim of this research work was to investigate on the ball filling estimation of miduk semi-autogenous (sag) mill via an utilized method. miduk copper concentrator is located in kerman province, iran, and its size reduction stage includes one gyratory crusher which feeds one sag mill (9.75 dia.(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). after sag mill, a tromm...

This study aimed to discover the effect of learning method and motivation on improvement throwing catching ball for elementary school students. The samples were 60 students acquired using treatment by level 2x2 design with tukey test a =0.05 level. results show 1) groups A1 A2 obtained Fh Ft, i.e., 17.9 4.15; therefore, there is an between group individual throw-catch skills, Qh = 8.54 dan Qt 3...
