Inhibitory effect of subthreshold transcranial magnetic stimulation on the stretch-evoked long latency response of forearm muscles
… mechanisms is the “long-latency response” (LLR), which is evident as a burst of muscle activity occurring 50–100 ms following an imposed limb displacement. Although the neural processing of these long latency responses through the cortical circuits has been roughly distinguished, it is still …

The development of the role of the Bank of England as a Lender of Last Resort, 1870-1914
… the Bank of England as a lender of last resort (LLR) in the 1870-1914 period. It also considers how the Bank reacted to the failure, or the possibility of failure, of financial institutions. This concern with crises arises out of fractional reserve banking: banks keep only a small proportion of …

Astronomical seeing conditions as determined by turbulence modelling and optical measurement
… optimal scientific output. Lunar Laser Ranging (LLR) is one of the space geodetic techniques to be hosted on-site. This technique requires optical (or so-called astronomical) seeing conditions, which allow for the propagation of a laser beam through the atmosphere without excessive beam …

Aspects of generative and discriminative classifiers
… analysis (LDA) with linear logistic regression (LLR). Then we studied extensively two hybrid-learning techniques, namely the hybrid generative-discriminative algorithm~\citep{Raina:03} and the generative-discriminative tradeoff (GDT) approach~\citep{Bouchard:04}, for combining the generative and …

Evaluation of Efferent Unmasking Using Cortical Auditory-Evoked Potentials
… of the MOCR does not significantly affect LLR latency and inter-amplitude. One possible factor that influences these results is the duration of the measurement session, as it may reduce the MOCR effect. Another possibility is that the reduction in cochlear output caused by MOCR activation …
