Long-term thinking and voluntary resource sharing are two distinctive traits of human nature.Across three experiments (N=1,082), I propose a causal connection: Sometimes people are generous because they think about the future.Participants were randomly assigned to either focus on the present or the future and then made specific decisions in hypothe
In this paper, an optimal PID controller is introduced for an antagonistic variable stiffness actuator (AVSA) based on Hammerstein models.A set of Hammerstein models is developed for the AVSA using the voltage difference method.For each stiffness level, linear Left Link Cover and nonlinear Hammerstein models are identified using the least squares m
In recent years, the development of an environmentally friendly quantum dots (QDs) embedded luminous solid by a simple method has attracted considerable attention.In this Infinity Heart-Shaped Acrylic Plaque study, semiconductor ZnS QDs were successfully prepared in an inorganic matrix of amorphous glass, which yielded beneficial broad-band emissio
The aim of this study was to assess the usefulness of oregano (Origanum vulgare L.) and thyme (Thymus vulgaris L.) extracts to decrease mycotoxin contents and improve the hygienic quality of maize (Zea mays L.) silage.Under laboratory conditions, maize silage samples were fermented with oregano (OE), thyme (TE), oregano and thyme mixture (MIX), and
