Hrnciar and Haviar [3] gave a method to a construct a graceful labeling for all trees of diameter at most five. Based on their method and the methods described in Balbuena et al [1], we shall describe a new construction for gracefully labeled trees by attaching trees to the vertices of a tree admitting a bipartite graceful labeling.

let z2 = {0, 1} and g = (v ,e) be a graph. a labeling f : v → z2 induces an edge labeling f* : e →z2 defined by f*(uv) = f(u).f (v). for i ε z2 let vf (i) = v(i) = card{v ε v : f(v) = i} and ef (i) = e(i) = {e ε e : f*(e) = i}. a labeling f is said to be vertex-friendly if | v(0) − v(1) |≤ 1. the vertex balance index set is defined by {| ef (0) − ef (1) | : f is vertex-friendly}. in this paper ...

The labeling index was estimated in human tumor biop sies with a new method in which antinucleoside antibody and immunoperoxidase staining are used. Excellent agree ment of the [3H]thymidine autoradiography labeling index and the antinucleoside immunoreactivity labeling index was obtained in cell aspirates from solid tumor and fluid specimens taken before radiation or chemotherapy as well as in...

The performance of parallelized connected component labeling can be improved in two ways: faster local labeling and faster interprocessor communication. Suzuki et al. describe one method of improving the speed of the local labeling procedure through the use of another table that remembered component labels. In speeding up global information dissemination, one may either allow each component to ...

A nonlinear probabilistic model of the relaxation labeling (RL) process is implemented in the speaker identi"cation task in order to disambiguate the labeling of the speech feature vectors. In this proposed algorithm, the deterministic labeling of the vector quantization (VQ)-based speaker identi"cation is relaxed by means of introducing initial probabilistic weights to the labeling process of ...

Aspect-oriented Fine-grained Opinion Extraction (AFOE) aims to extract the aspect terms, corresponding opinion terms and sentiment polarity in a target sentence. Most previous methods treat AFOE as word-level or span-level task, which ignore complementarity of these two tasks. To integrate merits information, we construct an end-to-end Span-based Multi-Table Labeling (SpanMTL) framework. SpanMT...

Labeling of viruses can be used to reveal viral infection pathways and screen potential anti-viral drugs. Complex procedures, including virus cultivation, purification and labeling are involved in traditional virus labeling methods. And the manipulation of living virus brings risk to researcher health. In this work, we report a general method for site-specific labeling of the envelope virus in ...

Continuous labeling by flow-driven adiabatic inversion is advantageous for arterial spin labeling (ASL) perfusion studies, but details of the implementation, including inefficiency, magnetization transfer, and limited support for continuous-mode operation on clinical scanners, have restricted the benefits of this approach. Here a new approach to continuous labeling that employs rapidly repeated...

Pharmacokinetic and organ distribution studies of liposomal drugs in humans are a challenge. A direct labeling method using (99m)Tc-N,N-bis(2-mercaptoethyl)-N',N'-diethyl-ethylenediamine (BMEDA) complex to label the commercially available pegylated liposomal doxorubicin, Doxil, has been introduced. Biodistributions of (99m)Tc-Doxil in normal rats were performed to evaluate the feasibility of us...
