Local fibred right adjoints are polynomial

For any locally cartesian closed category ℰ, we prove that a local fibred right adjoint between slices of ℰ is given by a polynomial. The slices in question are taken in a well-known fibred sense.

Correlation between ultrasonographic signs and axillary lymph node metastasis in breast cancer by univariate and multivariate analysis

Objective To explore the correlation between ultrasonographic signs of breast cancer and axillary lymph node metastasis.Methods The sonographic features of 146 patients with 151 breast malignant noplasms(66 with metastasis,85 without metastssis)and axillary lymph nodes were retrospectively analyzed.The results of ultrasonography were compared with pathology.The relationship between these signs and axillary lymph node metastasis were evalued by univariate(Chi-square test)and multivariate analysis(Logistic regression).Agreement was measured with k statistics between ultrasonographic signs and pathology.The correlation between sonographic criteria and axillary lymph node metastasis were evalued.Results The primary tumor size,grade of tumor flow and maximum cortex thickness correlated well with axillary lymph node metastasis by univariate and multivariate analysis(X~2=37.939,13.153,69.128;OR=6.632,3.714,35.442,respectively,P<0.01).Agreement was moderate(k=0.501,0.690,0.673).The primary tumor size,grade of tumor flow and maximum cortex thickness could predict metastatis accurately.The primary tumor size,grade of tumor flow correlated well with maximum cortex thickness(X~2=40.132,33.128,P<0.01).The distance from tumor to skin,changes of fibred structures and some other features could predict metastatis.Conclusions Evaluation of ultrasonographic signs by univariate and multivariate analysis is useful in predicting of breast cancer metastasis to axillary lymph nodes before operation.

The fibred product near-rings and near-ring modules for certain categories

In somes categories, there are structures that look very much like groups, and they usually are. These structures are called group-objects and were first studied by Eckmann and Hilton (1). If our category has an object T such that hom(X, T)= {tx}, a singleton, for each object X ∈ Ob , T is called a terminal object. Our category must have products; i.e. for A1,…, An ∈;. Ob , there is an object A1 × … × An ∈ Ob and morphisms pi: A1 × … × An → Ai so that if fi: X → Ai, i = 1, 2, …, n, are morphisms of , then there is a unique morphism [f1, …, fn]: X → A1 × … × An such that for i = 1, 2, …, n.
