Geometry of elytra opening and closing in some beetles (Coleoptera, Polyphaga).

Elytra in beetles move actively, driven by their own muscles, only during transient opening and closing. The kinematics of these movements have been inadequately described, sometimes controversially. Our goal was a quantitative 3-D description of diverse active movements of the elytra, in terms of directions of the axes of elytra rotation. Broad opening and closing was video recorded in beetles...

Elytra boost lift, but reduce aerodynamic efficiency in flying beetles.

Flying insects typically possess two pairs of wings. In beetles, the front pair has evolved into short, hardened structures, the elytra, which protect the second pair of wings and the abdomen. This allows beetles to exploit habitats that would otherwise cause damage to the wings and body. Many beetles fly with the elytra extended, suggesting that they influence aerodynamic performance, but litt...

Opening and Closing in Tandem.

This interest relates to the overlapping Venn diagrams that demonstrate substantial intersection between these 2 diseases. AS increases with increasing age; although its morbidity and mortality have been documented since seminal work in the 1950s and 1960s (2), within the past 15 years, interest has grown exponentially. This growth is based on factors including, among others, the following: 1) ...

Dynamic visual cues induce jaw opening and closing by tiger beetles during pursuit of prey.

In dynamic locomotory contexts, visual cues often trigger adaptive behaviour by the viewer, yet studies investigating how animals determine impending collisions typically employ either stationary viewers or objects. Here, we describe a dynamic situation of visually guided prey pursuit in which both impending prey contact and escape elicit observable adaptive behaviours in the pursuer, a predato...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
