Asymptotically good sequences of linear ramp secret sharing schemes have been intensively studied by Cramer et al. in terms of sequences of pairs of nested algebraic geometric codes [4]-[8], [10]. In those works the focus is on full privacy and full reconstruction. In this paper we analyze additional parameters describing the asymptotic behavior of partial information leakage and possibly also partial reconstruction giving a more complete picture of the access structure for sequences of linear ramp secret sharing schemes. Our study involves a detailed treatment of the (relative) generalized Hamming weights of the considered codes.

The purpose of this study was to describe and assess the feasibility of a new intra-articular approach in the treatment of cranial cruciate ligament deficiency in dogs using an artificial ligament and a new bone-anchor system. Twelve canine cadavers weighting 26 to 45 kg were used in this ex-vivo study. Special tibial and femoral screws, two helicoils, and a high resistance artificial fiber compose the implant. Surgery was performed using the mean cranio-lateral approach to the stifle joint. Helicoil and tibial screw, connected to the fiber, were inserted in the center of the tibial insertion area of the cranial cruciate ligament. The fiber was passed over-the-top, tensioned, and fixed to the femoral screw, previously inserted with the helicoil in the distal part of the femur. Surgery was completed in all the cases. Occasional problems found during the insertion of the helicoils and screws were resolved with simple procedures. Post-operative clinical assessment showed negative cranial drawer test, negative cranial tibial thrust, and normal range of motion. Radiographic evaluation showed an appropriate positioning of both tibial and femoral implants in all the cases. The results of the first surgical appraisal of this new technique are encouraging, although further studies are necessary to demonstrate the in vivo efficacy of this procedure.

A 4-year-old intact female, mixed breed dog was presented with a complaint of dyspnea. Clinical examination revealed symptoms related to disease of the upper airways. Radiographic findings were consistent with tracheal collapse associated with anomalies involving the seventh cervical vertebra and the first ribs bilaterally. Radiographs were highly suggestive of cervical ribs; computed tomography and ultrasound examination allowed complete characterization and better localization of the anomalies with relationship to the adjacent muscle and vasculature. Cervical ribs are malformations widely described in human medicine, but only sporadically in dogs. Herein, we discuss etiological, clinical, diagnostic, and therapeutic aspects of cervical ribs and possible correlations between the cervical ribs and other anatomical anomalies noted in this dog.
