WebOct 1, 2024 · Above the saturation voltage, the leakage current was decreasing as the temperature increased. In order to evaluate the effects of saturation voltages ( VS) on time-to-failure (TTF) of the capacitors, VS were first determined at +2°C and +25°C, then voltage accelerating tests were conducted at 85°C under 1.6 times of rated voltage. WebTime-to-treatment failure (TTF) is the interval from initiation of chemotherapy to its premature discontinuation. Since early discontinuation can occur due to various reasons …

This paper presents a … WebIn the only study using TTF as the primary end point, TTF was defined as the time from randomization until progression, relapse, or death from any cause. Of note, only one trial used both PFS and TTP as efficacy end points; for this trial, the definition of TTP differed from that of PFS in considering only deaths from breast cancer, whereas PFS included …
WebA recently proposed methodology for electromigration (EM) assessment in on-chip power/ground grid of integrated circuits has been validated by means of measurements, performed on dedicated test grids. IR drop degradation in the grid is used for defining the EM failure criteria. Physics-based models are involved for simulation of EM-induced …
