Diamond dicing
Many queries that constrain multiple dimensions simultaneously are difficult to express and compute efficiently in both Structured Query Language (SQL) and multidimensional languages. We introduce the diamond cube operator, filling a gap among existing data warehouse operations. It aids decision support and analysis by facilitating the execution of simultaneous multidimensional queries on data ...
متن کاملStop the dicing in hematopoiesis
MicroRNAs (miRNAs) belong to an abundant class of highly conserved small (22nt) non-coding RNAs. MiRNA profiling studies indicate that their expression is highly cell type-dependent. DICER1 is an essential RNase III endoribonuclease for miRNA processing. Hematopoietic cell type- and developmental stage-specific Dicer1 deletion models show that miRNAs are essential regulators of cellular surviva...
متن کاملDicing algorithm-Explore multidimensional space with probability
Nonlinear inverse problem is still not so satisfying with the application of available search algorithm. Here a new search algorithm, dicing algorithm (DA) is presented, which offers potential in both the optimization and error analysis. It works as an approach of NA-Gibbs sampler but provides simpler cell, so it can sample among the neighborhood of numerous local optima. Because of its simplic...
متن کاملSplicing and dicing with a SERRATEd edge.
T he maturation and quality control of mRNA in eukaryotes is a tightly regulated, multistep process that begins on nascent transcripts. A 7-methyl guanosine (7MeG) cap structure is added to the 5 end of pre-mRNA as it emerges from the exit channel of RNA Polymerase II. The multifunctional nuclear cap-binding complex (CBC), consisting of two protein subunits (CBP80 and CBP20), assembles at the p...
متن کاملA New Stream Cipher: Dicing
In this paper, we will propose a new synchronous stream cipher named DICING, which can be viewed as a clock-controlled one but with a new mechanism of altering steps. With the simple construction, DICING has satisfactory performance, faster than AES about two times. For the security, there have not been found weakness for the known attacks, the key sizes can be 128bits and 256bits respectively. .
