To understand biological processes, biologists typically study how perturbations of protein functions affect the phenotype. Protein activity in living cells can be influenced in many different ways: by manipulation of the genomic information, by injecting inhibitory antibodies, or, more recently, by the use of ribonucleic acid-medicated interference (RNAi). All these methods have proven to be e...

Catalonia has been one of the most commercialized and industrialized regions of Spain during the twentieth century. Home of the first industrial revolution during the nineteenth century, it started to adopt technologies and organizational structures of the Second Technological Revolution by the end of that period and the first third of the twentieth century. During the period 1890-1935 Catalan ...

In this paper, we present a method to construct a loop transformation that simultaneously reshapes the access patterns of several occurrences of multidimensional arrays along certain desired access directions. First, the method determines a direction through the original iteration space along which these desired access directions are induced. Subsequently, a unimodular transformation is constru...

People routinely learn how to manipulate new tools or make new movements. This learning requires the transformation of sensed movement error into updates of predictive neural control. Here, we demonstrate that the richness of motor training determines not only what we learn but how we learn. Human subjects made reaching movements while holding a robotic arm whose perturbing forces changed direc...

The paper addresses the following problem: given a set of man-made shapes, e.g., chairs, can we quickly rank and explore the set of shapes with respect to a given avatar pose? Answering this question requires identifying which shapes are more suitable for the defined avatar and pose; and moreover, to provide fast preview of how to alter the input geometry to better fit the deformed shapes to th...

The propagation of ultrashort laser pulses in the optical fibers is connected with a plenty of interesting and practically important phenomena. Unique dispersive and nonlinear properties of the optical fibers lead to various scenarios of the pulse evolution which are resulted in particular changes of the pulse shape, spectrum and chirp. The modern age of the optical fibers starts from the 1960s...

We easily recognize objects and faces across a myriad of retinal images produced by each object. One hypothesis is that this tolerance (a.k.a. "invariance") is learned by relying on the fact that object identities are temporally stable. While we previously found neuronal evidence supporting this idea at the top of the nonhuman primate ventral visual stream (inferior temporal cortex, or IT), we ...
