In the field of motor control, two hypotheses have been controversial: whether the brain acquires internal models that generate accurate motor commands, or whether the brain avoids this by using the viscoelasticity of musculoskeletal system. Recent observations on relatively low stiffness during trained movements support the existence of internal models.(More)
Based on satellite observations of Earth's time variable gravity field from the Gravity Recovery and Climate Experiment (GRACE), it is possible to derive variations in terrestrial water storage, which includes groundwater, soil moisture, and snow. Given auxiliary information on the latter two, one can estimate groundwater storage variations. GRACE may be(More)
In a previous study, we evaluated six 2D barcodes using eight criteria for standardization potential: omnidirectional symbol reading, support for low-resolution cameras, reading robustness under different lighting conditions, barcode reading distance, error correction capability, security, support for multiple character sets, and data capacity. We also(More)
This paper describes a longitudinal analysis of the vowel development of two Japanese infants in terms of spectral resonant peaks. This study aims to investigate when and how the two infants become able to produce categorically separated vowels, and covers the ages of 4 to 60 months in order to provide detailed findings on the developmental process of(More)
Controversy exists regarding the similarity between depression as seen in patients with epilepsy and in those with idiopathic major depression. The objective of this study was to examine whether anger is a distinctive feature of depression in epilepsy. Participants included 487 adult patients with epilepsy (study group) and 85 patients with idiopathic major(More)
Aggression in patients with temporal lobe epilepsy (TLE) may have phenomenological and neurobiological heterogeneity. In the present study, we targeted patients with TLE who showed aggression and evaluated the effects of lamotrigine on this symptom using the Buss-Perry Aggression Questionnaire (BAQ), which is based on a four-factor model that includes(More)
The use of colours in 2D barcodes is challenging. This is even more so in barcodes for mobile devices. Although 2D barcodes are fast becoming the ubiquitous tool for mobile computing, most implementations considered monochromatic 2D barcodes. A few colour 2D barcodes are emerging but these implementations only utilises a limited number of colours. In this(More)
Modulating the dynamics of a nonlinear autoregressive model with a radial basis function (RBF) of exogenous variables is known to reduce the prediction error. Here, RBF is a function that decays to zero exponentially if the deviation between the exogenous variables and a center location becomes large. This paper introduces a class of RBF-based(More)
