We study rigidity percolation for random central-force networks on the bondand site-diluted generic triangular lattice. Here, each site location is randomly displaced from the perfect lattice, removing any special symmetries. Using the pebble game algorithm, the total number of floppy modes are counted exactly, and exhibit a cusp singularity in the second derivative at the transition from a rig...

he curious phenomenon referred to as "floppy corn syndrome" reared (or lowered, as it were) its ugly head in some fields in Indiana and Ohio back in early June. The term "floppy corn" simply describes a young (V5 to V8) plant that has fallen over because of the absence of an established nodal root system at the crown of the plant. Affected plants may survive if the mesocotyl remains intact long...

In a developing country like India, classification and identification of the species of Anopheline mosquitoes in control operations of mosquito-borne diseases is of paramount importance. The WHO monograph, which describes the taxonomic data in the form of a pictorial key is generally difficult to understand by a non-taxonomist. Utilizing the principles of ID3 algorithm, a novel rule-based syste...

The floppy Anterior Cruciate Ligament (ACL) sign is a well-established arthroscopic and MRI indicator of Posterior Cruciate Ligament (PCL) insufficiency. We explored the diagnostic and therapeutic options in such cases by retrospectively analyzing the management of a series of five consecutive cases of iatrogenic floppy ACL reconstructions which resulted in fixed posterior drawer. All patients ...

PURPOSE Floppy eyelid syndrome (FES) presents nonspecific ocular surface irritation. The hypothesis for the current study was that one contributing factor is the abnormality in tear film dynamics. METHODS Sixteen patients with FES were consecutively examined. Tear film dynamics were evaluated by kinetic tear interference images, infrared thermometry, water evaporation rate, tear break-up time...

We introduced an analysis to identify structural characterization of two-dimensional regular and amorphous networks. The analysis was shown to be reliable to determine the global network rigidity and can also identify local floppy regions in the mixture of rigid and floppy regions. The eigenmode analysis explores the structural properties of various networks determined by eigenvalue spectra. It...
