We propose a scheme to generate persistent current in driven-dissipative systems which can be described by the generalized Gross-Pitaevskii (GP) equation. Our proposal consists of fabricating rachet-potential shape loss-rate profile, simultaneously breaks time-reversal symmetry and parity-inversion symmetry. Unlike existing schemes using rachet potential Hermitian systems, no dynamic drive is n...

The aetiology of painful dorsal wrist ganglia remains obscure. In a prospective study we investigated the link between a painful dorsal wrist ganglion and wrist joint abnormality with wrist arthroscopy before excision of the ganglion. Of 16 wrists arthroscoped 12 were abnormal, 10 had an abnormal scapholunate joint, and two had abnormal lunatetriquetral joints. We think that painful dorsal wris...

In this article, we define a new non-archimedean metric structure, called cophenetic metric, on persistent homology classes of all degrees. We then show that zeroth together with the and hierarchical clustering algorithms number different metrics do deliver statistically verifiable commensurate topological information based experimental results obtained datasets. also observe resulting clusters...

Joint injection of the elbow is a useful diagnostic and therapeutic tool for the family physician. In this article, the injection procedures for the elbow joint, medial and lateral epicondylitis, and olecranon bursitis are reviewed. Persistent pain related to inflammatory conditions responds well to injection in the region. Indications for elbow joint injection include osteoarthritis and rheuma...

BACKGROUND The prevalence of persistent low back pain with the involvement of lumbar facet or zygapophysial joints has been described in controlled studies as varying from 15% to 45% based on the criteria of the International Association for the Study of Pain. Therapeutic interventions utilized in managing chronic low back pain of facet joint origin include intraarticular injections, medial bra...

a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...

We study graded response attractor neural networks with asymmetrically extremely dilute interactions and Langevin dynamics. We solve our model in the thermodynamic limit using generating functional analysis, and find (in contrast to the binary neurons case) that even in statics, for T > 0 or large α, one cannot eliminate the non-persistent order parameters, atypically for recurrent neural netwo...
