Folded nodes occur in generic slow-fast dynamical systems with two slow variables. Open regions of initial conditions flow into a folded node in an open set of such systems, so folded nodes are an important feature of generic slow-fast systems. Twisting and linking of trajectories in the vicinity of a folded node have been studied previously, but their consequences for global dynamical behavior...

Minimum storage regenerating codes have minimum storage of data in each node and therefore are maximal distance separable (MDS for short) codes. Thus, the number of nodes is upper bounded by 2, where b is the bits of data stored in each node. From both theoretical and practical points of view (see the details in Section 1), it is natural to consider regenerating codes that nearly have minimum s...

A European cost-effectiveness study has been conducted using published clinical trial data from multinational studies on chronic venous leg ulcers and pressure sores. Data relevant to UK chronic wound management practice have been extracted and are presented here. A total of 15 pressure sore studies involving 519 wounds, and 12 leg ulcer studies involving 843 ulcers were used in a pooled analys...

A mixture of microflora, including Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans, is found in burns traumatic wounds. In this study, piezoelectric inkjet printing was used to apply an antifungal agent, amphotericin B, antibacterial azithromycin, the surfaces gauze, silicon, aluminum. The vitro disk diffusion assay performed on unmodified, dimethyl sulfoxide vehicle-modifie...

All nail surgical procedures require the use of a tourniquet. The nail bed, being a very vascular structure, needs to be exsanguinated at the start and then a tourniquet needs to be tied at the base. A number of tourniquets have been described, including a Foley's catheter, a Penrose drain, a rubber strip or a rubber band. The present article explains the use of the easily available, improvised...
