LIDAR-based analyses of the first theropod dinosaur trackways known from the state of Arkansas, USA are reported. The trackways were found on a limestone bedding plane in the Albian De Queen Formation in an active gypsum quarry. Because limited access precluded thorough field study, fieldwork focused on preserving the entire site digitally with ground-based LIDAR, and detailed measurements were...

Abstract Not Forgotten by Sam Buttrey.

In Martinique or La Réunion, French authorities recently banned the use of pesticides for management “soil-borne pathogens” on pineapple after several decades intensive monoculture where natural balance between beneficial and harmful communities soil organisms has disappeared. Today, increasing infestation by nematode R. reniformis other causes severe damage to crop. New cropping systems with i...

in order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in isfahan region. protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and pollen. results showed that the longevi...

A disentanglement puzzle consists of mechanically interlinked pieces, and the puzzle is solved by disentangling one piece from another set of pieces. A string puzzle is a type of disentanglement puzzle, which consists of strings entangled with one or more wooden pieces. In this paper, we consider the generalized string puzzle problem whose input is the layout of strings and a wooden board with ...

Four experiments examined 3- and 4-year-olds' ability to communicate about containment and proximity relations. One hundred twenty-eight children either described where a miniature mouse was hiding in a dollhouse or they searched for the mouse after the experimenter described where it was hiding. The mouse was always hidden with a small landmark that was either in or next to a large landmark. W...

In this paper we formally verify that the Uniform Candy Distribution Puzzle is self-stabilizing: Given a valid start configuration, eventually the Puzzle will evolve to a ‘stable’ situation in which it will remain. In terms of verification, the Uniform Candy Distribution Puzzle forms a scalable parametrized distributed system: The Puzzle comes in various sizes, for each size of the Puzzle there...

We introduce a new kind of percolation on finite graphs called jigsaw percolation. This model attempts to capture networks of people who innovate by merging ideas and who solve problems by piecing together solutions. Each person in a social network has a unique piece of a jigsaw puzzle. Acquainted people with compatible puzzle pieces merge their puzzle pieces. More generally, groups of people w...

Reproductive division of labor is one of the defining traits of honey bees (Apis mellifera), with non-reproductive tasks being performed by workers while a single queen normally monopolizes reproduction. The decentralized organization of a honey bee colony is maintained in large part by a bouquet of queen-produced pheromones, the distribution of which is facilitated by contact among workers thr...
