The entrainment of brain oscillations through transcranial alternating current stimulation (tACS) delivered at off-peak frequencies.
… memory capacity. Studies 2 and 3 delivered tACS at off-peak theta frequencies (4Hz and 7Hz) and study 4 delivered tACS at off-peak gamma frequencies (40Hz and 70Hz) during a working memory task. This was done to ascertain whether such stimulation could alter working memory capacity, which …

Do somatosensory oscillations relate to tactile attention? Extracting the phase of transcranial Alternating Current Stimulation (tACS) during stimulus presentation.
… Transcranial alternating current stimulation (tACS) is a non-‐invasive brain stimulation method that involves the application of weak electric currents to the scalp. tACS provides the ability to entrain intrinsic oscillations to specific frequencies. Through the employment of new hardware, the …

La modelización conceptual de la mecánica newtoniana en estudiantes de física universitarios: una aplicación de la teoría de Ausubel de aprendizaje significativo
… taller de aprendizaje cooperativo-significativo, TACS, es el elemento que más influye en el aprendizaje significativo de los estudiantes. La investigación cuasi-experimental realizada (etapa IV) muestra que el TACS fortalece, en el grupo experimental, el aprendizaje significativo de conceptos y el …

Transcranial alternating current stimulation to areas associated with the human mirror neuron system reveals modulation to mu-suppression and corresponding behaviour
… of transcranial alternating current stimulation (tACS). This was achieved in six experiments; the first three established an efficient protocol to induce μ-suppression during action observation, and the last three demonstrated by means of tACS that activity in hMNS-related areas is directly …

Investigation of edge effects in thermoacoustic couple measurements
… short plates, called thermoacoustic couples or TACs, revealed serious discrepancies between theory and experiment. The discrepancies are worst at higher drive ratios (the ratio of the peak acoustic pressure amplitude at a pressure antinode to the mean pressure of the gas), where prominent …

Strategies towards high performance (high-resolution/linearity) time-to-digital converters on field-programmable gate arrays
… and expensive time-to-amplitude converters (TACs). A TDC can be implemented in ASIC and FPGA devices. Due to the low cost, flexibility,and short development cycle, FPGA-TDCs have become promising. Starting with a literature review, three original FPGA-TDCs with outstanding performance are …

New methods for the protection of embedded generators against the loss of utility networks.
… using the Transient Analysis of Control Systems (TACS) part of ATP. After extensive investigation it was decided that the problem was ideal for an Artificial Neural Network (ANN) solution. Further research indicated that the Multi-Layer Perceptron (MLP) with back-propagation learning had been used …

The development and implementation of a joint management procedure for the South African pilchard and anchovy resources
… anchovy ratio for the whole industry, calculates TACs (total allowable catches) on the basis of this selection, and then allocates quotas to each rights holder on the basis of a percentage right for each fishery (pilchard and anchovy). In contrast, the lTD method collapses separate rights for …

Novel mechanisms of DC and kilohertz electrical stimulation
… than low-frequency stimulation methods such as tACS.</p> <p>Effects of DC stimulation have been studied in neuronal depolarization/hyperpolarization, synaptic plasticity, and neuronal network modulation. Recent evidence suggests that DC stimulation can induce polarity-dependent water exchange …
