Low-dose CT: technique, reading methods and image interpretation
Figure 2. Transverse unenhanced low-dose CT scans show a slow-growing pulmonary nodule of the lower right lobe in a 61-year-old man. In 2012, the nodule was surgically removed and was found to be adenocarcinoma of the lung. The nodule measured 5.5 mm in 2007 (a), 8.5 mm in 2009 (b) and 11 mm in 2012 (c).

Tightly focused field modulated by spiral phase with an off-axis
When the topological charge of spiral phase is an integer, the transverse intensity patterns in focused fields are often donut-shaped under the low numerical-aperture (NA) optical system. However, for the case of the high NA optical system, the transverse intensity patterns are affected by the polarization state of incident light, due to ...

The equation that determines h r is different from the total spiral height of a transmissive SPP (h t).For a transmissive SPP, the difference of the optical path length (ΔL) between two normally incident beams becomes ΔL = (n r − 1)h t, where n r is the real part of refractive index (see the top of Fig. 1 A).Considering the phase difference Δϕ t = (2π/λ)ΔL …

Tit for Tat? The Spiraling Effect of Incivility in the Workplace
incivility can potentially spiral into increasingly intense aggressive behaviors. To gain an understanding of the mechanisms that underlie an "incivility spiral," we examine what happens at key points: the starting and tipping points. Furthermore, we describe several factors that can facilitate the occurrence and escalation of an inci-
