Abstract Three-dimensional viscoelastic flow numerical models for the polymer coextrusion process were established on basis of two different wall conditions and solved via finite element methods. The influence melt viscosity was investigated by analyzing die swell, interlayer interface stability field distribution under slip conditions, namely, sticky adhesive condition fully non condition. results indicate that in traditional with condition, change viscosity, but effects shell differ from...

With the continual increasing application requirements of broadband vibration energy harvesters (VEHs), many attempts have been made to broaden bandwidth. As compared adopted only a single approach, integration multi-approaches can further widen operating Here, novel two-degree-of-freedom cantilever-based triboelectric nanogenerator is proposed obtain high bandwidth by integrating multimodal harvesting technique and inherent nonlinearity broadening behavior due contact between surfaces. A...

Background No standardized criteria for surgical resection of parasagittal sinus meningiomas (PSM) have been established, and different strategies proposed. The aim the present study was to investigate efficacy safety a “radical” strategy in treatment PSM. Methods clinical histories, radiological findings, pathologic features, records 53 patients with PSM admitted by same team using were retrospectively analyzed between 2018 2023. Results Among cases, 16 (30.2%) had patent proper, 28 (52.8%)...

Tactile sensors, due to their unique advantages of high sensitivity, flexibility, and stability, have received increasing attention from researchers worldwide hold great promise for application a variety fields, particularly electronic skin. However, the majority tactile sensors are limited in ability meet demand multi-variable tests single-functionality. To address this issue, paper, we introduce novel type array pressure/temperature composite sensor that functions without any interference....

Abstract Microneedles, as an innovative drug delivery technology, demonstrate great potential for application due to their superior performance in transdermal delivery. Compared with traditional injection needles, microneedles can reduce pain and the risk of infection after insertion into skin, have organically combine other external technologies further enhance effectiveness therapeutic effect. However, achieve efficient delivery, design optimization must comprehensively consider mechanical...

Common autoimmune bullous diseases (AIBDs) include pemphigus and pemphigoid (BP), which are primarily caused by IgG autoantibodies against the structural proteins of desmosomes at cell-cell junction hemidesmosomes epidermal-dermal junction. Few studies have assessed nail changes in patients with or BP. In present study, we collected clinical data 191 AIBDs (108 83 BP) 200 control subjects. Nail were observed 77.0% (147/191), 77.8% (84/108), 75.9% (63/83) AIBDs, pemphigus, BP, respectively,...

The use of microneedles to transport drugs organisms is an important way transdermal delivery, and the preparation key its realization. In this paper, metal are prepared through a combined method cutting electrochemical etching whose parameters optimized as well. It studied first in paper influences machining parameters, which well, on shape microneedles, then rough stainless-steel needle bodies. conical easily be obtained with bevel-cutting tools. A short time will elapse for forming...
