Numerical analysis of the dynamic frequency responses of damaged micro-lattice core sandwich plates
(Professional Engineering Publishing Ltd, 2020-01)
In this work, a numerical analysis of the dynamic frequency responses of sandwich plates with micro-lattice core is presented. The finite element analysis is implemented in the commercial software Abaqus/Standard, calculating ...
Energy harvesting for autonomous thermal sensing using a linked E-shape multi-beam piezoelectric device in a low frequency rotational motion
(Academic Press Ltd - Elsevier Science Ltd, 2019-11-01)
This paper presents a multi-beam energy harvester (MBT2ML) capable to convert kinetic energy from rotational motion at low frequency (<3 Hz) into usable electricity. The energy conversion is achieved by using a piezoelectric ...

Feeding frequency, prey acceptance, and natural diet of the mygalomorph spider acanthogonatus centralis goloboff 1995 (Araneae: Nemesiidae)
(Academia Sinica, 2018-06)
The family Nemesiidae is the second most diverse family of Mygalomorphae spiders. Acanthogonatus centralis (Nemesiidae) is commonly found in hilly areas of central Argentina. These spiders are considered generalists due ...
Archetypal temporal dynamics of arid and semi-arid rangelands
(Elsevier Science Inc., 2021-03)
The way in which temporal dynamics structure ecological systems under the influence of a changing environment has long interested ecologists. Tackling the hierarchical structure of complex temporal patterns is a necessary ...
Frequency-dependent selection predicts patterns of radiations and biodiversity
(Public Library of Science, 2010-08)
Most empirical studies support a decline in speciation rates through time, although evidence for constant speciation rates also exists. Declining rates have been explained by invoking pre-existing niches, whereas constant ...

Non-linearities in the Rod and Cone Photoreceptor Inputs to the Afferent Pupil Light Response
(Frontiers Media SA, 2018-12)
Purpose: To assess the nature and extent of non-linear processes in pupil responses using rod- and cone-isolating visual beat stimuli. Methods: A four-primary photostimulating method based on the principle of silent ...
