INVERTED DISTANCE AND INVERTED WIENER INDEX
Advances and Applications in Discrete Mathematics, 2016The Wiener index is the sum of distances between all pairs of vertices of a (connected) graph. In this paper, we define two novel graph invariants: the inverted distance and the inverted Wiener index. The inverted distance between any two different vertices u and v of a simple connected graph G is defined as: i(u, v) = D - d(u, v) + 1, where D denotes ...

Applied Categorical Structures, 2009
The review partly uses the authors' abstract. As the authors notice, monoidal objects (pseudomonoids) in monoidal bicategories share many properties with monoidal categories. The existence of (left or right) duals in monoidal categories permits to define dualization operations; a related definition was suggested for monoidal objects by \textit{B.

Unilaterally Invertible Normals are Invertible
The Quarterly Journal of Mathematics, 2001Let \(A\) be a complex unital Banach algebra with unit. An element of \(A\) is hermitian if it has real spatial numerical range when considered as an operator in \(\mathcal L(A)\). An element \(r\) is called normal if there are two hermitian elements \(s, t\) of \(A\) such that \(st = ts\) and \(r = s + it.\) It is shown that every normal element of ...

Annals of Otology, Rhinology & Laryngology, 1986
Two hundred twenty-three cases of inverted papilloma seen at this institution over a 35-year period were reviewed. The number of cases steadily increased over each 5-year period. Common presenting signs and symptoms, association with carcinoma, and results of surgical and radiographic treatment are presented.

Aesthetic Plastic Surgery, 1978
The author presents the anatomic, embryologic, and etiologic aspects and treatment of the inverted nipple.The Pitanguy technique for correction of this deformity consists of direct cutting of the fibromuscular tilts that hold the nipple in an inverted position, by means of a transareolomamillar incision.Associated mammary hypoplasia is corrected by ...

Inverting non-invertible trees
2018If a graph has a non-singular adjacency matrix, then one may use the inverse matrix to define a (labeled) graph that may be considered to be the inverse graph to the original one. It has been known that an adjacency matrix of a tree is non-singular if and only if the tree has a unique perfect matching; in this case the determinant of the matrix turns ...

Invertible Amphiphilic Homopolymers
Journal of the American Chemical Society, 2004Stimuli-responsive polymers and assemblies are viable candidates for the so-called "smart" materials. In this communication, we report a new class of amphiphilic homopolymers that forms micelle-like structures in polar solvents and inverted micelle-like structures in apolar solvents.
