An n-gon is called Napoleon if the centers of the regular ngons erected outwardly on its sides are vertices of a regular n-gon. In this note we obtain a new geometric characterization of Napoleon ngons and give a new proof of the well-known theorem of Barlotti Greber ([1], [3]) that an n-gon is Napoleon if and only if it is affine regular. Moreover, we generalize this theorem by obtaining an an...

The highly specialized nature of scientific research has erected substantial barriers between professional scientists and the laity, who have become distanced from the process of discovery. The Do-It-Yourself Biology movement seeks to remove these impediments, with community laboratories serving as vehicles for public engagement and participation in scientific inquiry. We describe our experienc...

Two proctophyllodid species described by Herbert F. Berla were studied, re-described and their generic status was re-evaluated. A new genus, Lamellodectes gen. nov. (Proctophyllodidae: Pterodectinae), is erected to accommodate Pterodectes ocelatus Berla, 1960 from the White-collared Foliage-gleaner, Anabazenops fuscus (Vieillot) (Furnariidae), and a new species, L. distinctus sp. nov., from the...

Abstract With technological advancement, drone has emerged as unmanned aerial vehicle that can be controlled by humans to fly or reach a destination. This may autonomous well, where the itself is intelligent enough find shortest obstacle-free path destination from designated source. Be it planned smart city even wreckage site affected natural calamity, we imagine buildings, any surface-erected ...

A new wolf spider genus, Serratacosa gen. nov., is erected based on the type and species, S. medogensis et sp. nov. two newly combined himalayensis (Gravely, 1924) (from Hogna Simon, 1885) multidontata (Qu, Peng & Yin, 2010) Pardosa C.L. Koch, 1847). All of them are from southern slopes Eastern Himalayas. Descriptions genera a redescription provided together with digital images, illustratio...
