标准号: BS ISO/IEC 15459-4-2006

摘要： This part of ISO/IEC 15459 specifies a unique, non-significant, string of characters for the unique identifier for supply chain management. The character string is intended to be represented in a bar code label or other AIDC media attached to the item to meet supply chain management needs. To address management needs different classes of items are recognized in the various parts of ISO/IEC 15459, which allows different requirements to be met by the unique identifiers associated with each class. The rules are defined for the unique identifiers for supply chain management to identify the unique occurrence of an item, understood to mean the layers zero and one as will be defined in two future International Standards (ISO 17367 and ISO 17366, respectively).

摘要： Background: Monoclonal antibodies are used extensively throughout the biomedical sciences for detection of antigens, either in vitro or in vivo. We, for example, have used them for quantitation of proteins on "reverse-phase" protein lysate arrays. For those studies, we quality-controlled > 600 available monoclonal antibodies and also needed to develop precise information on the genes that encode their antigens. Translation among the various protein and gene identifier types proved non-trivial because of one-to-many and many-to-one relationships. To organize the antibody, protein, and gene information, we initially developed a relational database in Filemaker for our own use. When it became apparent that the information would be useful to many other researchers faced with the need to choose or characterize antibodies, we developed it further as AbMiner, a fully relational web-based database under MySQL, programmed in Java. Description: AbMiner is a user-friendly, web-based relational database of information on > 600 commercially available antibodies that we validated by Western blot for protein microarray studies. It includes many types of information on the antibody, the immunogen, the vendor, the antigen, and the antigen's gene. Multiple gene and protein identifier types provide links to corresponding entries in a variety of other public databases, including resources for phosphorylation-specific antibodies. AbMiner also includes our quality-control data against a pool of 60 diverse cancer cell types (the NCI-60) and also protein expression levels for the NCI-60 cells measured using our high- density "reverse-phase" protein lysate microarrays for a selection of the listed antibodies. Some other available database resources give information on antibody specificity for one or a couple of cell types. In contrast, the data in AbMiner indicate specificity with respect to the antigens in a pool of 60 diverse cell types from nine different tissues of origin. Conclusion: A

关键词： heart failure   bundle branch block   pacing   prognosis   stress echocardiography   cardiac resynchronization therapy   responders  

摘要： BACKGROUND Cardiac resynchronization therapy (CRT) provides benefit for congestive heart failure (CHF), but predictors of the clinical response are debated. OBJECTIVE The aim of this prospective study was to assess the predictive role of dobutamine stress echocardiography (DSE) in identifying a suitable candidate for CRT. METHODS From March 2001 to December 2003, 71 CHF patients were prospectively enrolled on the basis of four criteria: New York Heart Association (NYHA) class III and IV;QRS >= 150 ms with a left bundle branch block pattern, and left ventricular ejection fraction (LVEF) <= 35% under optimal medical treatment. The combined endpoints were hospital readmission for class IV CHF, heart transplant (HT), and CHF-related death. RESULTS The 67 patients completing the study presented with the following characteristics: age (70 +/- 10 years;11 women);etiology (idiopathic in 44, ischemic in 23);NYHA class (40 in class III and 27 in class IV);LVEF 26% (+/- 5 %);QRS duration (190 +/- 28 ms);6-minute walk test 330 m (+/- 108);peak oxygen uptake 10.7 (+/- 3.3 mL/kg/min);mitral insufficiency in 42 (>= III grade);interventricular (IV) delay (62 +/- 21 ms);and intraventricular dyssynchrony in 30 patients. Over the follow-up period of 12.1 +/- 8.7 months, 20 (29.9%) of 67 patients presented with at least one! hemodynamic event: hospitalization for CHF in 19 (28%) of 67, HT in 2 (3%) of 67, and CHF death in 7 (10%) 67. Univariate analysis identified NYHA class (P = .03), LVEF (P = .015), IV dyssynchrony before (P = .038) and after CRT (P = .0035), IV delay after CRT (P = .002), 6-minute walk distance (P = .01), and DSE Res+ (P = .008) as significant predictors of clinical events. A receiver operating curve established a cut-off value of 1.25 for the DSE responders (Res+: 34 patients at 10 mu g/kg/min infusion rates), and the improvement at the 10 mu g/kg/min level was 41% +/- 7% in Res+ and 29% +/- 8% in nonresponders (P <.0001). With a cut-off value of 1.25-fold the LVE

摘要： This paper presents fingerprint image enhancement and rotation schemes that improve the identification accuracy with the pixel-parallel processing of pixels. In the schemes, the range of the fingerprint sensor is adjusted to the finger state, the captured image is retouched to obtain the suitable image for identification, and the image is rotated to the correct angle on the pixel array. Sensor and pixel circuits that provide these operations were devised and a test chip was fabricated using 0.25-mu m CMOS and the sensor process. It was confirmed in 150,000 identification tests that the schemes reduce the false rejection rate to 6.17% from 30.59%, when the false acceptance rate is 0.1%.

摘要： The release of genetically engineered apple trees raises the question of their potential environmental impact, and the transfer via pollen of transgenes to cross-compatible cultivars of Malus domestica and Malus species is deemed to be the greatest source for environmental exposure. The hybrid TNR 31-35, a descendant of Malus sieversii var. sieversii f. niedzwetzkyana, carrying a homozygous, dominant gene responsible for red pigmentation in all plant parts, was used to assess gene flow in an apple scion repository of genetic resources. The red pigmentation provides a morphological marker that enables large-scale evaluation of cross-fertilization under natural conditions. In two consecutive years, 60 and then 56 apple trees of 38 different Malus domestica cultivars were selected to serve as pollen-receptor trees. In these two years, 6876 and then 5513 seeds, respectively, were gathered from pollen-receptor trees located at different distances, 2-100 m from 15 pollen-dispenser trees. In total, 11 797 seedlings were examined. An average of 1.8% and 1.4%, respectively, of all seedlings obtained showed red-colored leaves. Considering both years of sampling, 69% of the seeds fertilized by TNR 31-35 were found at less than 10 m from the nearest pollen-dispenser tree. Almost 91% of all seeds fertilized by TNR 31-35 were found at less than 60 m from the nearest pollen-dispenser tree, which is equal to 30 adjacent trees along the row. In this study, pollen was dispersed at least 104 m. After phenotypical evaluation, seedlings selected as red-colored were investigated by simple sequence repeat (SSR) analysis. Each seedling was tested with at least one heteromorphic SSR-marker, which allows the verification of TNR 31-35 as the male parent. All but four seedlings showed one allele specific for the appropriate fruiting tree and the second allele specific for the pollen-dispenser TNR 31-35. © ISBR, EDP Sciences, 2006.

关键词： change-point   time-series   Moving F   quality control   process control   MCMC  

摘要： In a not-necessarily-stationary time-series, a Moving F statistic can identify points of change in the nature of the series model (the estimate of the underlying data-generating process), in its parameters, in residual variability, or in any combination of these. In addition, it can uncover changes masked by a reduction in residual variability. Patterns in the forces giving rise to the data may often be perceived. To form the Moving F, a theory of the process or a regression method on a baseline sample estimates the series model and the residual mean square about it is calculated. This series model is extended past the baseline with residuals assumed to be normally distributed. The Moving F is calculated as the moving average of squared deviations about the series model in ratio to the baseline mean square. The Moving F crossing the critical F identifies a change in the series model, i.e. signals its presence and location. In our experience, this Moving F method is easier to use than other commonly employed change-point identifiers (CUSUM, EWMA, data-based bandwidth selection, MCMC) and has been found to work in several situations where some other identifiers fail. (MCMC is more general, but requires advanced statistical ability.) Examples given are monitored prostate specific antigen in a post-treatment prostate cancer patient and detection of Harold Shipman's medical murders. Moving F is 'simple and general' in the sense of both simultaneously;we have not found another relatively simple method to be as general. Published in 2005 by John Wiley & Sons, Ltd.
