We modified the Adaptive Noise Cancellation procedure of Widrow et al. (11 for use as an adaptive band-pass filter to process Steady-State Evoked Potentials (SSEPs). The adative filter yields an approsimate 10 dB improvement in Signal to Noise Ratio over the Discrete Fourier Transform. Introduction Steady-state evoked potentials (SSEPs) are comprised of narrow-band signals buried in broad-band ...

The vast majority of cardiac arrest (CA) survivors remain comatose at hospital arrival. Around one-half of these patients suffer from severe hypoxic encephalopathy leading to death or unresponsive wakefulness. Early outcome prognostication may reduce futile intensive care and suffering for next of kin. Several early prognostic markers have shown high positive predictive value for poor outcome i...

Considering the large deviations of activity and current in Asymmetric Simple Exclusion Process (ASEP), we show that there exists a non-trivial correspondence between joint scaled cumulant generating functions two ASEPs with different parameters. This mapping is obtained by applying similarity transform on deformed Markov matrix source model order to obtain target model. We first derive this fo...

OBJECT The authors conducted a study to evaluate repetitive transcranial electrical stimulation (TES) to assess spinal cord motor tract function in individuals undergoing spine surgery, with emphasis on safety and efficacy. METHODS Somatosensory evoked potentials (SSEPs) were elicited using standard technique. Muscle electromyographic values were measured in response to a three- or four-pulse...

The Student Spaceflight Experiments Program (SSEP) is a United States national science, technology, engineering, and mathematics initiative that aims to increase student interest in science by offering opportunities to perform spaceflight experiments. The experiment detailed here was selected and flown aboard the third SSEP mission and the first SSEP mission to the International Space Station (...

Objective: To determine the optimal timing of somatosensory evoked potential (SSEP) recordings and the additional value of clinical and biochemical variables for the prediction of poor outcome in patients who remain comatose after cardiopulmonary resuscitation (CPR). Methods: A prospective cohort study was conducted in 32 intensive care units including adult patients still unconscious 24 hours ...
