A threshold-voltage-shift compensation and suppression method for active matrix organic light-emitting diode (AMOLED) displays fabricated using a hydrogenated amorphous silicon thin-film transistor (TFT) backplane is proposed. The proposed method compensates for the threshold voltage variation of TFTs due to different threshold voltage shifts during emission time and extends the lifetime of the...

Over the last decade, the consequences of acoustic trauma on the functional properties of auditory cortex neurons have received growing attention. Changes in spontaneous and evoked activity, shifts of characteristic frequency (CF), and map reorganizations have extensively been described in anesthetized animals (e.g., Noreña and Eggermont, 2003, 2005). Here, we examined how the functional proper...

OBJECTIVES To investigate the changes over a workshift in fingertip tactile perception thresholds in users of impact wrenches exposed to intermittent hand transmitted vibration. A further aim was to assess the relation between acute changes in tactile sensation, sensorineural disorders, and vibration dose. METHODS The study populations consisted of 30 workers exposed to vibration (16 men and ...

The goal of the study was to enlarge knowledge of discrimination of complex sound signals by the auditory system in masking noise. For that, influence of masking noise on detection of shift of rippled spectrum was studied in normal listeners. The signal was a shift of ripple phase within a 0.5-oct wide rippled spectrum centered at 2 kHz. The ripples were frequency-proportional (throughout the b...

OBJECTIVES Apoptosis of outer hair cell (OHC) can be identified through nuclear staining by specific nuclear changes. The change of filamentous actin (F-actin) is also involved in early cell death process. The study was designed to investigate OHC death along the whole length of the organ of Corti. METHODS BALB/c hybrid mice were used in this study. The noise group was exposed to white noise ...

We reexamine degradation and recovery dynamics in the negative bias temperature instability (NBTI) of p-channel metal oxide semiconductor field effect transistors (PMOSFETs) by making use of the recently developed in situ polyheater technique. The capability of switching the device temperature extremely fast and almost arbitrarily allows for measuring differently stressed devices directly after...

6 This paper presents an analytically tractable dynamic game in which agents jointly use a 7 resource. The resource replenishes fully but collapses irreversibly should total use exceed 8 a threshold. The initial level of resource use is known to be safe. Because experimentation 9 only reveals whether the threshold has been crossed or not, and the consequence of crossing 10 the threshold is disa...
