The marked focal length on the lens is the actual focal length of that lens, that will never change. But, to help explain or understandwhat lens this would be on a FF 35mm, the crop factor was marketed since most of us understand FF 35mm lens coverage. What you do is multiply the ...
A minimum distance, h, between breaks is imposed, which depends on the length of the times series. We have set h=0.15. Accordingly, we restricted the maximum number of breaks to five (Bai and Perron 2003). To deal with potential serial correlation, we employ a HAC covariance matrix ...
The field in the anode bore acts as a diverging lens of a focal length fA that moves the virtual vertex to z = − w′S = fA wS(wS − fA)− 1. The lens also enlarges β → β′ and in the paraxial approximation (i.e., when we can put tan β ≅ sin β ≅ β),...

Enhancing the capability of WiMAX mesh network is one of the focal problems nowadays. In this paper, we propose a centralized scheduling algorithm based on... C Yang,Z Liu,Y Yi - IEEE 被引量: 72发表: 2007年 Cross-layer design for tree-type routing and level-based centralised scheduling ...
The second-level contrast analysis examining the differential response between medial group and lateral group stimulation showed that a number of focal anatomical sites exhibited significant difference (Fig.3d) including in Thalamus, preCG, postCG, SFG, MFG, IFG, Precuneus, AG, STG, ITG, and infe...
(1, 2, 4, 8, 16 and 32 km)25were calculated for each variable using variable radius focal mean analysis. These selected scales span the range of brown bear habitat requirements, from resources within core habitats to the extent of reported home ranges of the species48, and correspond to ...
The full-length blots were presented in supplementary information (Fig. S3). Bar, 25 μm. Full size image Assessment of glial cell activation in the dorsal root ganglia (DRG) after intrathecal, spinal nerve and intra-DRG injection To determine the transgene expression and glia activation of ...
To end on a simpler idea: Safe Pareto improvements may be Schelling points (a.k.a. focal points) in some settings. For instance, you might imagine a setting in which the above justifications don’t quite apply. Then SPIs might stand out by virtue of standing out in slight alterations of...
The following parameters for the therapeutic US transducer were used: 1) frequency: 0.85 MHz (or 1.04 MHz); 2) focal length: 135.0 mm (or 151.0 mm); 3) diameter: 20 cm; 4) the scanning method: point-by-point method; 5) depth: the distance on the US channel from the center of ...
