Familial Claw-Foot

Congenital split foot (lobster claw) and triphalangeal thumb.

Claw length recommendations for dairy cow foot trimming

The aim was to describe variation in length of the dorsal hoof wall in contact with the dermis for cows on a single farm, and hence, derive minimum appropriate claw lengths for routine foot trimming. The hind feet of 68 Holstein-Friesian dairy cows were collected post mortem, and the internal structures were visualised using x-ray µCT. The internal distance from the proximal limit of the wall h...

The foot plantar pressures for patients with hallux valgus combines with or without claw toe

Methods 7 severe HV patients (2 male and 5 female, 14 foot) and 7 patients suffered HV combine with claw toe (HVC) (1 male and 6 female, 14 foot) were recruited in this study. The F-Scan in-shoe system (Tekscan, Inc.) were used to record the data of plantar pressure at a sampling frequency of 50 Hz. Subjects were instructed to wear the custom shoes with F-Scan sensor pad and perform a 5 meter w...

Claw-free Graphs VI. Colouring Claw-free Graphs

In this paper we prove that if G is a connected claw-free graph with three pairwise non-adjacent vertices, with chromatic number χ and clique number ω, then χ ≤ 2ω and the same for the complement of G. We also prove that the choice number of G is at most 2ω, except possibly in the case when G can be obtained from a subgraph of the Schläfli graph by replicating vertices. Finally, we show that th...

Equimatchable Claw-Free Graphs

A graph is equimatchable if all of its maximal matchings have the same size. A graph is claw-free if it does not have a claw as an induced subgraph. In this paper, we provide, to the best of our knowledge, the first characterization of claw-free equimatchable graphs by identifying the equimatchable clawfree graph families. This characterization implies an efficient recognition algorithm.
