We present AvatarReX, a new method for learning NeRF-based full-body avatars from video data. The learnt avatar not only provides expressive control of the body, hands and face together, but also supports real-time animation rendering. To this end, we propose compositional representation, where are separately modeled in way that structural prior parametric mesh templates is properly utilized wi...

Over the past few years, a number of geographers, inspired by social theory of various derivations, attempted to recenter the focus of research about GIS. In place of a technical agenda, they sought to make space for studies of the implications of GIS for society at many scales and through many processes. While much of their critique serves useful purposes, the focus on implications adopts a mo...

The development of functional genomic resources is essential to understand and utilize information generated from genome sequencing projects. Central to the development of this technology is the creation of high-quality cDNA resources and improved technologies for analyzing coding and noncoding mRNA sequences. The isolation and mapping of cDNAs is an entrée to characterizing the information tha...

In this paper, we present the first cryptographic preimage attack on the full MD5 hash function. This attack, with a complexity of 2, generates a pseudo-preimage of MD5 and, with a complexity of 2, generates a preimage of MD5. The memory complexity of the attack is 2×11 words. Our attack is based on splice-and-cut and localcollision techniques that have been applied to step-reduced MD5 and othe...

Full simulations of homogeneous isotropic turbulence containing a homogeneous passive scalar were made at low Reynolds numbers and various Prandtl numbers. The results show that the spectral behavior of the two fields are quite similar; both fields decay as power-law functions of time. However. the decay exponent is quite dependent on both the Reynolds and Prandtl numbers. The decay exponent of...
