Background. This study investigated the clinicopathologic significance of extranodal tumor extension in colorectal adenocarcinoma with lymph node metastasis. Method. Included were 419 patients who underwent curative resection for primary colorectal adenocarcinoma. Results. Extranodal tumor extension was observed more frequently in tumors with ulceroinfiltrative gross type (p = 0.026), higher hi...

The distance between two permutations of the same set X is the number of pairs of elements being in di erent order in the two permutations Given a poset P X a pair L L of linear extensions is called a diametral pair if it maximizes the distance among all pairs of linear extensions of P The maximal distance will be called the linear extension diameter of P and is denoted led P Alternatively led ...

A novel speech bandwidth extension method based on audio watermark is presented in this paper. The time-domain and frequency-domain envelope parameters are extracted from the high-frequency components of speech signal, and then these parameters are embedded in the corresponding narrowband speech bit stream by the modified least significant bit watermark method which uses perception property. At...

(a) P is a nonempty set; (b) ≤ is a partial ordering of P; i.e., ≤ is transitive, reflexive relation in P (and so p ≤ q ∧ q ≤ p ∧ p 6= q is not forbidden); (c) for all p ∈ P, p ≤ 1. (1 need not be the only such maximum element.) We shall often write P for 〈P,≤,1〉. Let P be a poset. If p is an element of P, then an extension of p is a q ∈ P such that q ≤ p. Two elements of P are compatible if th...

BACKGROUND/AIMS The purpose of this study was to compare the diagnostic validity of two-dimensional (2D) and three-dimensional (3D) ultrasonography (US) when predicting the extrathyroidal extension of papillary thyroid cancer. METHODS All 2D data were interpreted in real time and 3D data were stored, rendered using tomographic ultrasound imaging (TUI), and then reviewed retrospectively. RES...

A cotensor product A HP of an H-Hopf Galois extension A and a C-coalgebra Galois extension P , such that P is an (H,C)-bicomodule, is analyzed. Conditions are stated, when A HP is a C-coalgebra Galois extension and when there exists a strong connection on A HP . Two examples are given, in both, A and P are Matsumoto spheres, and H = C = C(U(1)).

Household food security remains a challenge in South Africa. The national government instituted the Integrated Food Security Strategy (IFSS) programme which identifies household agricultural production as an important element of improving household-level food security. Agricultural extension is well positioned to help achieve this aim, but its current contribution is unknown. This study identif...

We prove a fundamental conjecture of Rubin on the structure local units in anticyclotomic $\mathbb{Z}_p$-extension unramified quadratic extension $\mathbb{Q}_p$ for $p\geq 5$ prime. Rubin's underlies Iwasawa theory deformation CM elliptic curve over field at primes $p$ good supersingular reduction, notably main terms $p$-adic $L$-function. As consequence, we an inequality Birch and Swinnerton-D...
