Tumors of the eye and nervous system often exhibit an arch-like arrangement of nuclei, called rosettes. Pathologists are able to identify rosettes [full circles] and the presence of partial rosettes [semi-circles] and interpret this as a sign of differentiation in a tumor. However, there is no objective method to quantitate the many partial rosettes that are obvious or not obvious to the naked ...

The paper presents a deductive framework for proving program equivalence and its application to automatic verification of transformations performed by optimizing compilers. To leverage existing program analysis techniques, we reduce the equivalence checking problem to analysis of one system a cross-product of the two input programs. We show how the approach can be effectively used for checking ...

Frequency-hopping (FH) spread-spectrum techniques employ sequences with Hamming correlation properties meeting suitable criteria. In this correspondence novel families of FH sequences having optimal autoand cross-correlation properties with respect to the well-known Lempel-Greenberger bound are developed through combinatorial product type constructions. This provides us new optimal families of ...

Interorganizational alliances are widely recognized as critical to product innovation, particularly in high technology markets. Many new product development (NPD) alliances tend to be asymmetric, that is, they are formed between a larger firm and a smaller firm. These asymmetric alliances typically result in changes in the shareholder values of the partner firms. Are the changes in shareholder ...

OBJECTIVES To investigate the sugar, energy and caffeine content of sugar-sweetened drinks marketed and consumed as energy drinks available in the UK. STUDY DESIGN We carried out a cross-sectional survey in 2015 and 2017 of energy drinks available in the main UK retailers. METHODS The sugar (sugars g/100 mL), energy (kcal/100 mL), caffeine (mg/100 mL) and serving size were collected from pr...

Upcoming weak lensing surveys on wide fields will provide the opportunity to reconstruct the structure along the line of sight tomographically by employing photometric redshift information about the source distribution. We define power-spectrum statistics, including cross correlation between redshift bins, quantify the improvement that redshift information can make in cosmological parameter est...

Interval routing is an attractive space-efficient routing method for point-to-point networks (introduced in [13] and [15]) which has found industrial applications in the INMOS T9000 transputer design. Surveys of the principal theoretical results as well as recent trends in the area of interval routing can be found in [16, 5, 11]. Interval routing is based on compact routing tables, in which the...

In this study we compare product development strategies and practices of five companies in the durable goods industries: one each in the United States (equipment), Sweden (aerospace), Germany (electric motors), Hungary (transportation equipment), and Japan (business machines, cameras/video). In particular, we focus on the concept development phase of new product development and the attend to th...

Cosmetic products are inherently personal. Many people rely on product reviews when choosing to purchase cosmetics. However, reviewers can have tastes that vary based on personal, demographic or cultural background. Prior work has discussed methods for generating attribute-based explanations for item ratings on cosmetic products, based on associated text-based reviews. This paper focuses on eva...

Excerpt] The second annual Product and Service Innovation Conference was held in February 2005 in Park City, Utah. The conference brought together over 40 distinguished and upcoming scholars from 30 flagship universities all over the United States. The purpose of the conference is to unite leading scholars in the fields of operations management and marketing and to promote an open dialog among ...
