A novel prosthetic knee joint with a parallel spring and damping mechanism

open access: yesInternational Journal of Advanced Robotic Systems, 2016
Prosthetic knee joint (PKJ) is an important apparatus for trans-femoral amputees to regain walking ability. This study has two objectives: (1) to design a high performance and low-cost passive PKJ and (2) to evaluate the performance of the PKJ.

Compensating linkage for main rotor control [PDF]

open access: yes, 1981
A compensating linkage for the rotor control system on rotary wing aircraft is described. The main rotor and transmission are isolated from the airframe structure by clastic suspension.

(E)-N′-(2-Thienylmethylidene)-p-toluenesulfonohydrazide

open access: yesActa Crystallographica Section E, 2010
The S—N(H)—N=C linkage in the title molecule, C12H12N2O2S2, is non-planar [torsion angle = 15.5 (1)°] as the amino N atom is pyramidally coordinated.

Generalized Linkage Construction for Constant-Dimension Codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2019
A constant-dimension code (CDC) is a set of subspaces of constant dimension in a common vector space with upper bounded pairwise intersection. We improve and generalize two constructions for CDCs, the improved linkage construction and the parallel ...

Interface solitons in locally linked two-dimensional lattices

open access: yes, 2011
Existence, stability and dynamics of soliton complexes, centered at the site of a single transverse link connecting two parallel 2D (two-dimensional) lattices, are investigated.

A mixed indium–iron lithium diphosphate, In0.51Fe0.49LiP2O7

open access: yesActa Crystallographica Section E, 2011
The structure of In0.51Fe0.49LiP2O7 consists of a three-dimensional network constructed from (InIII/FeIII)O6 octahedra and P2O7 groups. Each MIIIO6 octahedron is linked to six PO4 tetrahedra belonging to five different P2O7 groups and shares two corners ...

A Hybrid Genetic Linkage Map of Two Ecologically and Morphologically Divergent Midas Cichlid Fishes (Amphilophus spp.) Obtained by Massively Parallel DNA Sequencing (ddRADSeq)

open access: yesG3: Genes, Genomes, Genetics, 2013
Cichlid fishes are an excellent model system for studying speciation and the formation of adaptive radiations because of their tremendous species richness and astonishing phenotypic diversity.

A scalable approach for discovering conserved active subnetworks across species. [PDF]

open access: yesPLoS Computational Biology, 2010
Overlaying differential changes in gene expression on protein interaction networks has proven to be a useful approach to interpreting the cell's dynamic response to a changing environment. Despite successes in finding active subnetworks in the context of
