The latter derivation structure is J-valid as being composed of the J-valid derivation structure D′ and J-valid rules (∧ elimination and → elimination are J-valid, because sr and sr are in J ).
this means that if it is S-valid with respect to J, it is S-valid with respect to J when viewed as a one-step derivation structure.
Then a derivation structure D in L S0) (i.e. a derivation structure containing only propositional variables as atoms) is defined to be universally valid with respect to J iff for every S and every v, Dv is S-valid with respect to Jv.
The aim of this study was to compare MDCT-derived apparent structure measures with HR-pQCT-derived structure measures as the standard of reference, and to evaluate possible differences in the derivation of apparent structure measures using two different MDCT devices (64-slice vs. 320-slice) with two different protocols (120 kVp and 200 mA vs. 135 kVp and 400 mA).
Thirty six compounds were synthesized and evaluated in vitro for their ability to inhibit LAT, in vitro activity against latent MTB, in vivo activity using Mycobacterium marinum infected zebra fish and cytotoxicity as steps toward the derivation of structure-activity relationship (SAR) for lead optimization.
Thus, although it is possible to shrink the FOV to 6 cm and decrease the in-plane pixel size to 117 × 117 µm for radius imaging, substantial benefits for the derivation of structure measures remain hypothetical.
This paper presents a method for automated derivation of product structures from 3D assembly models.
The systematic derivation of possible structures of visual servos enabled the creation of software patterns within the MRROC++ (Zieliński et al., 2007) [29] robot programming framework facilitating their implementation.
Hereunder we present a derivation of such structures for the proposed polyphase orders Bt={Pt,Nss,lcm(Pt,Nss)}.
Despite similar morphologic appearances, upper- and lower-tract UCs have been proposed to represent unique entities, based on their differing locations and embryonic derivation from distinct structures [ 1].
