A note on the minimum skew rank of a graph
Full text linkThe minimum skew rank of a graph over a field
is the smallest possible rank among all skew symmetric matrices
over , whose (,)-entry (for ) is nonzero whenever
is an edge in and is zero otherwise. We give some new properties of
the minimum skew rank of a graph, including a characterization of the graphs
with cut vertices over the infinite field such that
, determination of the minimum skew rank of -paths
over a field , and an extending of an existing result to show that
for a connected graph
with no even cycles and a field , where is the matching
number of , and is the largest possible rank among
all skew symmetric matrices over

Review article
No full textIn eukaryotic cells, the trans-Golgi network (TGN) serves as a platform for secretory cargo sorting and trafficking. In recent years, it has become evident that a complex network of lipid-lipid and lipid-protein interactions contributes to these key functions. This review addresses the role of lipids at the TGN with a particular emphasis on sphingolipids and diacylglycerol. We further highlight how these lipids couple secretory cargo sorting and trafficking for spatiotemporal coordination of protein transport to the plasma membrane
