One is to put one's nuclear forces on high alert and conduct military exercises. Another is to ratchet up one's rhetoric and make irrevocable commitments to use force. This risks leading to nuclear war through human or technical error, miscalculation or insanity.In this thesis we review ...
It has been found that for diatomic molecules the relation between the bond force constant,k0, and the internuclear distance,re,is quite accurately given by the expressionk0(re—dij)3= 1.86×105, wheredijis a constant depending only on the rows in the periodic table in which the two elemen...
It is shown empirically that for diatomic molecules consisting of nontransition elements the relation between the harmonic force constant, ke, and the equilibrium internuclear distance, Re, is quite accurately given by the simple universal expression ke = (ZA + δA)(ZB + δB)/2nA+nB-2Re3,...
In this regard, note that certain correlations appear to exist between the nuclear sizes and RNA transcription levels2,46; and that the activity of DNA polymerase was found to be sensitive for macromolecular crowding47,48,49. Context-dependent polarization is important for the functional plasticity...
As was later discovered, the bomber gap did not actually exist. More From Britannica nuclear strategy: Mutual assured destruction The growth of nuclear parity between the U.S. and the U.S.S.R., the inevitability of other nations producing atomic bombs, the worldwide abhorrence of the ...
driving the export of the complex. Exportin can also take advantage of this FG concentration gradient. Concentration gradients of different FG repeats provides a traction force and restrains directionality, thereby contributing to the high transport efficiency of NPCs. This model also explains the biolo...
The existence of strong binding partners in the nucleus can be another driving force of nuclear translocation of cytosolic proteins. We identified SRm160 as a partner protein in the nucleus (Fig. 2). However, the interaction with SRm160 does not appear to determine the nuclear localization of ...
The driving question: does maxRNA exist? Cells use surface molecules for self-presentation, intercellular recognition, and extracellular interactions. Discoveries of cell-surface receptors, glycans, and functional lipids have made fundamental impacts on biology [28,29,30]. Our driving question is whethe...
5f, g). Interestingly, a study also based on overexpression systems detected the interaction between these same importins and YAP, but no additional approaches were used86. These results suggest that either Imp7-independent alternative entry routes exist for nuclear YAP or indirect effects on other...
Through brute-force simulations of passive diffusion, we directly characterize the effect of protein size on the passive diffusion rate. We rationalize the observations by examining an ensemble of configurations realized by the nup mesh in the absence of any proteins, arriving at a general method ...
