Three types of source data degrading factors are investigated: image blurring, image noise and iris segmentation errors. Two most popular methods of template creation, Gabor and Log-Gabor transforms are involved. CASIA and NDIRIS public domain databases are used for tests. It is shown that the ...
At the microscopic level, remodeling has been shown to involve different cell types. In prior work, blood vessel regression in the rat cornea was characterized by macrophages closely associated with degrading capillary walls15. In the retina, disruption of endothelial-pericyte associations results in ...

The ubiquitin-proteasome pathway acts rapidly, degrading HIF-1␣ in cells in culture with a protein half-life of approximately 5 min (32). Although less extensively studied, HIF-2␣, the recently identified analogue of HIF-1␣, appears to be similarly regu- lated (9). Several cell ...

λ indicates the degrading effect of the target gene's expression value y [t - 1] at time point t - 1 on the target gene's expression value y [t] at time point t and ε[t] denotes the stochastic noise due to the modeling error and the measuring error of the target gene's expres...
Depending on the detector, the scatter signal can reduce the differential signal-to-noise by 20%. Furthermore, a Monte Carlo study of the interaction of x-rays within typical fluoroscopic imaging detectors (metal plate/phosphor screen) demonstrates the degrading effect of energy absorption noise on...
A larger spot might introduce more noise and interference, compromising the precision of phase recovery and subsequently degrading the optical field quality. Figure 4 shows the intensity distribution and mode purity of the generated HG30 mode and HG50 mode at the target plane under different beam ...
[11]. Papain, a broad-spectrum proteolytic enzyme less destructive than other proteases, digests various ECM components, facilitating the release of viable single cells from diverse tissues [12]. DNase I prevents cell clumping by degrading DNA from lysed cells [13]. Selecting the appropriate ...
This noise refers to any element that may interfere with the communication process, degrading the message, so its meaning will not be the intended one. Cultural differences can cause the noise during communication, so certain phrases or words can generate confusion and misunderstanding. Also, it ...
