Ancillary Services Market Design in Distribution Networks: Review and Identification of Barriers

Energies, 2020
The high proliferation of converter-dominated Distributed Renewable Energy Sources (DRESs) at the distribution grid level has gradually replaced the conventional synchronous generators (SGs) of the transmission system, resulting in emerging stability and

Heschl's gyrus is more sensitive to tone level than non-primary auditory cortex [PDF]

, 2002
Previous neuroimaging studies generally demonstrate a growth in the cortical response with an increase in sound level. However, the details of the shape and topographic location of such growth remain largely unknown.

Generation-expansion planning with linearized primary frequency response constraints

Global Energy Interconnection, 2020
As renewable energy resources increasingly penetrate the electric grid, the inertia capability of power systems has become a developmental bottleneck. Nevertheless, the importance of primary frequency response (PFR) when making generation-expansion plans

The responses of floodplain primary production to flood frequency and timing [PDF]

Journal of Applied Ecology, 2001
Summary  River regulation and abstraction have dramatically altered the natural flow regime of many rivers world‐wide, but experimental investigations of the biological effects are infrequent. In the mid‐region of the Murray River, Australia, river regulation has reduced the frequency and duration of spring floods and increased the frequency of summer

Low-Frequency Local Field Potentials and Spikes in Primary Visual Cortex Convey Independent Visual Information [PDF]

, 2008
Local field potentials (LFPs) reflect subthreshold integrative processes that complement spike train measures. However, little is yet known about the differences between how LFPs and spikes encode rich naturalistic sensory stimuli.

Uncomfortable images produce non-sparse responses in a model of primary visual cortex [PDF]

, 2015
The processing of visual information by the nervous system requires significant metabolic resources. To minimize the energy needed, our visual system appears to be optimized to encode typical natural images as efficiently as possible.
