There is a growing body of literature investigating point-light biological motion perception. Based solely on the kinematics of a handful of dots representing the body and major joints of a human actor, observers can extract complex information such as gender from point-light displays. Many previous studies have used artificially generated point-light animations to investigate critical features...

In this paper, we propose to use a subfield of machine learning –grammatical inference– to measure linguistic complexity from a developmental point of view. We focus on relative complexity by considering a child learner in the process of first language acquisition. The relevance of grammatical inference models for measuring linguistic complexity from a developmental point of view is based on th...

Plant cell cultures could be used as an important tool for biochemical production, ranging from natural pigments to pharmaceutical products. Anthocyanin is affected by a variety of factors. Light, an important plant environmental factor, influences the anthocyanin production in vegetative plant tissues. Here, we have investigated the influence of the blue laser-diode (BLD) and red laser-He Ne (...

Erythema annulare centrifugum (EAC) is a disease of unknown etiology, although it has been variously associated with hypersensitivity reactions, infections, hormonal disorders, rheumatological and liver diseases, dysproteinemias, drugs, and occult tumors. García-Muret et al described a subtype of EAC with annual relapses that occurred in the summer.1 Nonetheless, in our hospital we have observe...

In past centuries, the evidence for God's existence seemed direct because a spiritual being was the only way to make sense of our world in its exquisite detail, beauty, and purpose. For uncountable millennia, it seemed obvious that the rising sun required a God to pull it across the sky. Springtime buds and flowers somehow had the spirit of an all-powerful God, who controlled the entire world a...

The objectives of this study were to evaluate the light fastness of selected natural dyes (madder, weld and woad) and the effect of some commonly used antioxidants and UV absorbers on the light fastness of these dyes. The photofading rate curves of madder and weld fixed on cotton correspond to type II fading rate curves described by Giles. These results are in concordance with those of Cox-Crew...

The appearance of objects in scenes is determined by their shape, material properties and by the light field, and, in contradistinction, the appearance of those objects provides us with cues about the shape, material properties and light field. The latter so-called inverse problem is underdetermined and therefore suffers from interesting ambiguities. Therefore, interactions in the perception of...

Although any genotype-phenotype relationships are a result of evolution, little is known about how natural selection and neutral drift, two distinct driving forces of evolution, operate to shape the relationships. By analysing ∼500 yeast quantitative traits we reveal a basic "supervisor-worker" gene architecture underlying a trait. Supervisors are often identified by "perturbational" approaches...

Recent advances in nanophotonic light trapping open up the new gateway to enhance the absorption of solar energy beyond the so called Yablonovitch Limit. It addresses the urgent needs in developing low cost thin-film solar photovoltaic technologies. However, current design strategy mainly relies on the parametric approach that is subject to the predefined topological design concepts based on ph...
