In the United States, corn (Zea mays L.) stover has been targeted for second generation fuel production and other bio-products. Our objective was to characterize sugar and structural composition as a function of vertical distribution of corn stover (leaves and stalk) that was sampled at physiological maturity and about three weeks later from multiple USA locations. A small subset of samples was...

This paper combines horizontal and vertical innovations to build an endogenous growth model that allows for structural change. Older technologies are continuously replaced by newer ones due to creative destruction and new technologies appear as a result of horizontal innovations and as a result of consumers’ preferences for variety. We assume fixed operational costs for the manufacturing sector...

Face recognition is an important area of research with many applications, including biometric security and searching face databases. This article describes an approach to recognize faces using eigenbands, which aim to capture the best features from facial characteristics. Faces are divided in vertical and horizontal hands. From each hand is extracted features using standard-PCA. Results show th...

Summary In this study, the seismic performance of hexagrid structures which are composed of horizontal and vertical hexagrid by using a transitional story, has been investigated. To this end, 10 models of 50-story hexagrid structures were designed. 9 models with horizontal hexagrid cells which transited to vertical cells using a transitional story, and a model of completely horizontal hexagrid ...

Upside-down inversion disrupts the processing of spatial relations between the features of a face, while largely preserving local feature analysis. However, recent studies on face inversion failed to observe a clear dissociation between relational and featural processing. To resolve these discrepancies and clarify how inversion affects face perception, the authors monitored inversion effects se...

By Alan Solomon W ITHIN the past decade, studies by molecular geneticists on the composition and organization of immunoglobulin (Ig)-coding genes at the DNA level have vastly increased our understanding of the genetic mechanisms responsible for generating antibody diversity and for linking Ig synthesis to cellular differentiation. This new information, which has far-reaching biological and clin...

In this note we discuss the role of fundamental structural properties in human and computer vision. A selection of well-known and less known facts concerning the perceptual value of symmetry, anisotropy and regularity is presented. Finally, computational deenitions of these basic features for textures are given and a few examples of their application shown.

MicroRNAs (miRNAs) guide Argonaute (Ago) proteins to target mRNAs, leading to gene silencing. However, Ago proteins are not the actual mediators of gene silencing but interact with a member of the GW182 protein family (also known as GW proteins), which coordinates all downstream steps in gene silencing. GW proteins contain an N-terminal Ago-binding domain that is characterized by multiple GW re...
