In general, if you want to apply u along a group of n of axes:
axis=: 2 : 0
u"(#n)@(n&|:)
)
This is I believe very close to the axis operator in APL if you are familiar
with it:
]m=: i.2 3 4
0 1 2 3
4 5 6 7
8 9 10 11
12 13 14 15
16 17 18 19
20 21 22 23
< axis 0 m
+++---
<"1 |: B
+---+---+
|0 2 4 6|1 3 5 7|
+---+---+
if this is not what you wanted, then try
<@,."1 |: B
+-+-+
|0|1|
|2|3|
|4|5|
|6|7|
+-+-+
