Despite significant research in backscatter communication over the past decade, key technical open problems remain underexplored. Here, we first systematically lay out design space for networking and identify applications that make an attractive primitive. We then 10 to be solved networking. These span across network stack include circuits, embedded systems, physical layer, MAC protocols as wel...

This paper proposes a novel framework for unsupervised audio source separation using a deep autoencoder. The characteristics of unknown source signals mixed in the mixed input is automatically by properly configured autoencoders implemented by a network with many layers, and separated by clustering the coefficient vectors in the code layer. By investigating the weight vectors to the final targe...

This paper describes a new design of the multipurpose cryptographic primitive ARMADILLO3 and analyses its security. The ARMADILLO3 family is oriented on small hardware such as smart cards and RFID chips. The original design ARMADILLO and its variants were analyzed by Sepehrdad et al. at CARDIS’11, the recommended variant ARMADILLO2 was analyzed by Plasencia et al. at FSE’12 and by Abdelraheem e...

The origin of the prehepatic cells was determined by tracing the movements of [H]thymidinelabelled grafts excised from medium-streak to 4-somite stage chick embryos and transplanted to the epiblast, streak and endoderm-mesoderm layer of similarly staged recipient embryos. Although exact definition of prehepatic areas was not possible because of the small number of grafts placed at each developm...

The boundary layer on a circular cylinder undergoes a transition to turbulence at, approximately, Re=2 x 105. This is accompanied with a significant reduction in drag. Using a stabilized finite element formulation, we have conducted two-dimensional computations for flow past a cylinder using a very fine mesh close to it. It has been shown by researchers earlier that the genesis and formation of...

Endoderm that forms the respiratory and digestive tracts is a sheet of approximately 500-1000 cells around the distal cup of an E7.5 mouse embryo. Within 2 days, endoderm folds into a primitive gut tube from which numerous organs will bud. To characterize the signals involved in the developmental specification of this early endoderm, we have employed an in vitro assay using germ layer explants ...

The primitive streak is the organizing center for amniote gastrulation. It defines the future embryonic midline and serves as a conduit of cell migration for germ layer formation. The migration patterns of endodermal and mesodermal precursors through the streak have been studied in great detail. Additional new breakthroughs recently have revealed the cell biological and molecular mechanisms tha...
