Sentence examples for stem blocking from inspiring English sources

From the 1920s to the 1960s, four hydroelectric dams were built by the California-Oregon Power Company COPCOO) and its successor PacifiCorp on the Klamath River main stem, blocking salmon migration and trapping sediment that formerly replenished downstream gravel bars used by spawning salmon.

Finding an assembly of these stem blocks from various sequences is the final objective.

A group of similar stems which is conserved across multiple sequences is referred to as a stem block.

While recursively growing the paths of stem blocks, one must also make sure that all currently included stem blocks must occur together in at least a user-defined number of sequences.

As explained earlier, each stem block here corresponds to possible occurrences of an individual node of the stem graph pattern discussed above.

The next step would be to build a directed graph where each node of the graph corresponds to a stem block.

OR-1 activation in the brain stem blocks opioid analgesic responses and contributes to the partial agonist property of buprenorphine (Bloms-Funke et al 2000).

An edge is drawn from a stem block b1 to a stem block b2 if stems from b1 are before that of b2 and form one of the three previously described consistent patterns with the stems of b2 in a sufficient number of sequences.

Another approach (Ji et al., 2004) applies graph theory to find stems conserved across multiple sequences first, and then assembles conserved stem blocks to form consensus structures in which pseudoknots are permitted.

As the Wnt pathway is crucial for CML and AML stem cells, blocking CD27 signaling and reducing Wnt pathway activity resulted in a reduction of LSC numbers and delayed disease progression.

In previous studies, we and others showed that GATA2 overexpression at high levels, similar to that seen in hematopoietic stem cells, blocked differentiation of hematopoietic stem cells and progenitors.
