Abstract
A barrier that includes a plurality of first wires that extend in a horizontal direction is provided. The barrier can include a plurality of second wires that extend in a vertical direction. The barrier can include at least one third wire that extends in a direction orthogonal to the vertical direction. The plurality of second wires and one or more wires of the plurality of first wires can form a first portion extending in a first plane defined by the vertical direction and the horizontal direction. The at least one third wire and at least one wire of the plurality of first wires can form a second portion extending in a second plane defined by the horizontal direction and a transverse direction. The plurality of second wires can be excluded from the second portion. The at least one third wire can be excluded from the first portion.
