We propose a new method for 3D navigation using a commodity stylus and tablet already in common use among 3D artists. SpikeNav exploits tilt sensitivity to provide a more direct interaction style. Conceptually the stylus is turned into a spike which the user can jab into the model by contact with the tablet; moving the stylus drags the model around and tilting it rotates it naturally, making th...

Signal transducers and activators of transcription (STATs) play key roles in growth factor-mediated intracellular signal transduction. In the present study using a constitutively active STAT5 mutant, we show that STAT5 has pleiotropic functions regulating cell proliferation, differentiation and apoptosis in an IL-3-dependent Ba/F3 cell line. The mutant STAT5 possessed constitutive tyrosine phos...

Of this algebra really only the first line should be unfamiliar, as the second line simply says that Pμ and Kμ are vectors and the last line is just the Lorentz algebra SO(p, q). Now to put this into a more intuitive form we imagine that we are in a bigger space with two extra coordinates which we call −1 and 0 (the remaining coordinates are then 1...p+ q). Now consider the algebra defined by t...
