We introduce Flexible Trees, a sketch-based layout adjustment technique. Although numerous tree layout algorithms exist, these algorithms are usually bound to fit within standard shapes such as rectangles, circles and triangles. In order to provide the possibility of interactively customizing a tree layout, we offer a free-form sketch-based interaction

Trees with Distinguishing Index Equal Distinguishing Number Plus One
The distinguishing number (index) D(G) (D′ (G)) of a graph G is the least integer d such that G has an vertex (edge) labeling with d labels that is preserved only by the trivial automorphism.

Tree compression with top trees [PDF]
We introduce a new compression scheme for labeled trees based on top trees. Our compression scheme is the first to simultaneously take advantage of internal repeats in the tree (as opposed to the classical DAG compression that only exploits rooted subtree repeats) while also supporting fast navigational queries directly on the compressed representation.

Antropogeni i tehnogeni uticaj na životnu sredinu pojačan je u poslednjoj deceniji XX veka. Taj trend se nastavlja i u XXI veku, a ofanziva globalizacije donosi nove ekološke probleme. Globalni ekološki problemi najviše pogađaju gradove.

Hash Trees Versus B-Trees [PDF]
Summary: The hash trees method of external hashing is known to have advantages for certain types of primary key distribution. In this paper the value of the method as a general indexing technique - for secondary keys as well as primary keys - is assessed, and comparison with the B-trees method is presented.

Efficient Tree Tensor Network States (TTNS) for Quantum Chemistry: Generalizations of the Density Matrix Renormalization Group Algorithm [PDF]
We investigate tree tensor network states for quantum chemistry. Tree tensor network states represent one of the simplest generalizations of matrix product states and the density matrix renormalization group.

After stating several tools which can be used to construct indecomposable tree modules for quivers without oriented cycles, we use these methods to construct indecomposable tree modules for every imaginary Schur root. These methods also give a recipe for

Colourings of (k-r,k)-trees [PDF]
Trees are generalized to a special kind of higher dimensional complexes known as \((j,k)\)-trees ([L. W. Beineke, R. E. Pippert, On the structure of \((m,n)\)-trees, Proc. 8th S-E Conf. Combinatorics, Graph Theory and Computing, 1977, 75-80]), and which
