Applying the property of positive unit resolution of B-spline, an MCV sufficient condition for the curve segments is obtained.

The positive unit (PU) was higher in tumor group and cancer group than that in normal group (P>amp;lt;0.

(2) Using deletion strategy, both positive unit lock resolution and input lock resolution are complete for a Horn set where the indexes of positive literals are greater than those of negative literals.

In special cases we identify the 'boundary primes' in terms of expressions of the form , where ε is a totally positive unit of F.

Positive Unit Hyperresolution Tableaux and Their Application to Minimal Model Generation

Most of the PDBu-positive units responded also to bradykinin, whereas only a few PDBu-positive units were sensitive to prostaglandin I2 and E2.

Of the 50 MAN-positive units tested, 20 showed a response to intra-arterial KCl; of these 20, 12 had a response to BK; 8 of these 12 units were additionally tested with capsaicin and all responded.

On totally positive units of real holomorphy rings

In this paper we will show that every totally positive unit of the real holomorphy ring of a formally real field is a sum of 2n-th powers of totally positive units for all natural numbersn.

However the prevention of HCV infection will be the goal, in addition to screening of donor blood and exclusion to a large degree of positive units likely to decrease the incidence of post-transfusion hepatitis.

A new concept of positive unit(PU) was put forward for the quantitative expression of result of immunohistochemical reaction. Intensity of pure immunohistochemical reaction, which means the factor of background from section or smear had been discharged, was classified from 0 (for white) to 100(for black) based on the gray level of gray scale image. Each grade was defined as a positive unit on the paper. The formulas in the following for PU has been deduced, a. PU=100(G_α- G_β)/G_(max); b. PU=100(G_A-G_β)/A_(Aα)G_(max)....

In the formulas, G_α, G_β denote separatly the mean gray level of thestudying structure α and back ground β; G_A: mean gray level in an area A which containes α and β; G_(max): the maximum gray level of the instrument. A_(Aα): the area density of α phase in area A. Formula a could been used for the particles which are boundary obviously. Formula b could been used for all kind of sample including histological section and cytological smear despite the particles boundary are obvious or not. The value of PU varied directly with the reaction intensity. 513 cells of adenocarcinoma from hydrothorax and ascitic fluid dyed in EMA were measured. The results showed that the sensitivity is 94.2%, the specificity 100% and the accuracy 95.6%. The significance of PU and the problem about contrast dye were discussed.

An advanced quantitative method of immunohistochernical staining was developed,which brought about a new formula for testing and calculating positive unit(PU).According to this method,only the gray level and the area of defined area A and the phase a of positive products(or background 9) in A need to be tested; besides,the gray setting method needn't to be regarded.The formula is as follows:PU=100×|Ga-GA |/(AAβ.Gmax)=100×|Ga-GA|/[(1 -AAα).Gmax].G.and GA denote separately the mean gray level of the studying structure...

The expression of epidermal growth factor receptor (EGF-R) was studied in 38 laryngeal squamous cell carcinomas by immunohistochemical LSAB method using a monoclonal antibody against EGF-R, image analysis technique (IAT) was applied to measure the intensity of staining and indicated by positive unit(PU) instead of staining grade(0-Ⅲ). The results showed that the PU of EGF-R in poorly differentiated carcinomas were higher than that of well/moderately differentiated carcinomas (Ⅰ-Ⅱ) (P<0. 01),and it was also higher...

The expression of epidermal growth factor receptor (EGF-R) was studied in 38 laryngeal squamous cell carcinomas by immunohistochemical LSAB method using a monoclonal antibody against EGF-R, image analysis technique (IAT) was applied to measure the intensity of staining and indicated by positive unit(PU) instead of staining grade(0-Ⅲ). The results showed that the PU of EGF-R in poorly differentiated carcinomas were higher than that of well/moderately differentiated carcinomas (Ⅰ-Ⅱ) (P<0. 01),and it was also higher in the cases with cervlcal lymph node involvement. The EGF-R over expression harbinger good prognosis as shown by the Kaplan-Meier curves of survival(X2=8. 62 P<0. 05). It may provide a good parameter in the evaluation of prognosis.
