Most Altera devices do not have built-in basic latch elements, so a latch has to be constructed using Logic Cells (LCs). Unfortunately this then requires feedback around the LC to implement the storage. Here's a picture from the Technology Viewer showing a transparent latch: You can see th...
The promotion of the positive SAM in late spring of 2020 could partly be attributed to La Niña26, but is probably more closely related to the downward coupling from the near-record strengthening of the Antarctic stratospheric polar vortex that occurred in October and November 2020, which ...
It is not. This is not because catheter insertion is technically challenging or the discomfort it produces (doctors have little hesitancy in performing far more painful procedures). Instead, interpretation of the tracings is formidable.13 Precise calculation of intrinsic positive end-expiratory pressure...
Below is a plot of Intel CPU clock speed at introduction versus time. There is an abrupt plateau in 2003 where clock speed stopped increasing. Since then, CPU makers have been using multi-core technology to drive performance (effective performance extrapolated as the pink dashed line), but this...
Mechanistically, the cellular circadian clock oscillation is driven by interlocked positive and negative transcription/translational feed-back loops (TTFLs) carried into effect by a set of core clock genes (Figure 1a). Fundamental for the TTFLs are two basic-helix-loop-helix (bHLH) PAS transcriptio...

Table 1. Vertical absorption and emission energies and oscillator strengths (in parentheses) of the S11 state of TPF in the vacuum, solution of THF, and crystal environment. The absorption band peaked at 327 nm originates from the excitation to the bright 11𝜋𝜋∗1ππ* state. Both ...
