“…To study the mechanisms of re-program in 3D NAND, the stretched exponential function is used to model charge loss mechanisms [14], [15], [18]- [22]. As mentioned above, only two main charge loss components in IVS are considered in this work.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Generally well-known dominant failure mechanisms in NAND flash memory are detrapping [5,8,9], interface trap (N it ) recovery [10,11], and trap-assisted tunneling (TAT) [5,12,13]. We previously introduced a technique to separate the dominant mechanisms in NAND flash memory [14][15][16][17][18][19][20]. Each mechanism follows the Arrhenius law well (constant E a ), which means that each has its own activation energy (E a ) [14][15][16][17][18][19].…”

“…A similar breakdown of the distribution width was presented in [241], without accounting for detrapping. Other studies also identified charge detrapping as the dominant error source in highly-cycled NAND samples [242]. To overcome this limitation, several solutions have been proposed, including a dummy read [243] or a moving reference [244] scheme and a self-healing approach [245], where a built-in heater in the proximity of the tunnel oxide is used to accelerate damage recovery and prolong the endurance.…”
