where\(\alpha _1 + \alpha _2=1\)are two hyper-parameters in Tversky loss70that control the balance between false positive and false negative detections.\(\beta \)and\(\gamma \)are two hyper-parameters in Focal loss69where\(\beta \)balances the importance of positive/negative voxels, and...
False positive (FP): In cases wherein the actual value of the sample is negative, yet the projected outcome of the model is positive. True negative (TN): In cases wherein the actual value of the sample is negative, and the projected outcome of the model corresponds negatively as well. ...
Proven in the lab, fusion has recently entered the scale-up phase. The publicly funded international experiment ITER is building its first reactor, which experts believe will generate net positive energy by the late 2030s to mid-2040s. Meanwhile, more than 25 private companies...
However, automated nuclear segmentation and classification is faced with a major challenge in that there are several different types of nuclei, some of them exhibiting large intra-class variability such as the nuclei of tumour cells. Additionally, some of the nuclei are often clustered together. To...
it evolves into a character-driven fantasy that feels so real, even within a fictional setting. It's a drastically different series when compared to Matt Greoning's other projects, yet fans of eitherThe SimpsonsorFuturamacan find familiar positive qualities throughout. You might be able to catc...
In this case, dN1*/dt is negative—the amount of tracer in state 1 decreases with time—and thus the flux J12 is positive. The factor N1*/N1 in the denominator is called the specific activity of the added radioactivity. The units of J12 are in units of N per unit time. Measuring ...
2022/07/19 £75 million Nuclear Fuel Fund opens “Domestic production of nuclear fuel will be driven forward by a £75 million fund opening today (19 July 2022), with the cash boost set to encourage investment and expansion in new nuclear infrastructure while protecting high skilled jobs…...

To overcome the limitation of the current approaches, we propose TSFD-Net which consists of three parts: (a) a feature distillation backbone (FDB) to extract the distilled nuclei features pertaining to specific tissue types, (b) an efficient cross-scale weighted feature fusion (CWFF) via bidir...
(physical) interactions were included. Most up- and downregulated genes were not linked. However, three closely connected clusters comprisingchemokinesignaling viaCCR1andCCR5, antigen processing, and nuclear factor κB (NF-κB) signaling (including TNF) were among the upregulated transcripts (Figure 1...
