Wide-baseline street image interpolation is useful but very challenging. Existing approaches either rely on heavyweight 3D reconstruction or computationally intensive deep networks. We present a lightweight and efficient method which uses simple homography computing and refining operators to estimate piecewise smooth homographies between input views. To achieve the goal, we show how to combine homography fitting and homography propagation together based on reliable and unreliable superpixel discrimination. Such a combination, other than using homography fitting only, dramatically increases the accuracy and robustness of the estimated homographies...

BACKGROUND: In ventral hernia repair, when prosthetic material is placed intraperitoneally, it may lead to an inflammatory reaction resulting in adhesions between the mesh and abdominal viscera. Several meshes have been developed to minimize this process. In this experimental study, the ability of different combined meshes to attenuate the adhesion formation was examined. METHODS: Three commercially available lightweight porous combined meshes were placed intraperitoneally to repair an abdominal wall defect in rats: DynaMesh-IPOM (PVDF + PP), TiMesh (titanium-coated filament PP) and C-QUR/FX (omega-3 fatty acid-coated filament PP)...

Soft materials featuring both 3D free-form architectures and high stretchability are highly desirable for a number of engineering applications ranging from cushion modulators, soft robots to stretchable electronics; however, both the manufacturing and fundamental mechanics are largely elusive. Here, we overcome the manufacturing difficulties and report a class of mechanical metamaterials that not only features 3D free-form lattice architectures but also poses ultrahigh reversible stretchability (strain > 414%), 4 times higher than that of the existing counterparts with the similar complexity of 3D architectures...

REVIEW
Catherine A Matthews
Sacrocolpopexy remains the "gold standard" procedure for management of posthysterectomy vaginal vault prolapse with improved anatomic outcomes compared to native tissue vaginal repair. Despite absence of clinical data, sacrocolpopexy is increasingly being offered to women as a primary treatment intervention for uterine prolapse. While reoperation rates remain low, recurrent prolapse and vaginal mesh exposure appear to increase over time. The potential morbidity associated with sacrocolpopexy is higher than for native tissue vaginal repair with complications including sacral hemorrhage, discitis, small bowel obstruction, port site herniation, and mesh erosion...

BACKGROUND: The use of wide pore lightweight polypropylene mesh to improve anatomical outcomes in the surgical repair of prolapse has been hampered by mesh complications. One of the prototype prolapse meshes has been found to negatively impact the vagina by inducing a decrease in smooth muscle volume and contractility and the degradation of key structural proteins (collagen and elastin), resulting in vaginal degeneration. Recently, bioscaffolds derived from extracellular matrix have been used to mediate tissue regeneration and have been widely adopted in tissue engineering applications...

PURPOSE: The choice of mesh and anchoring device in laparoscopic ventral hernia repair is controversial. Clinically important long-term properties of mesh and anchoring device such as mesh shrinkage have been sparsely investigated. Furthermore, the effect of various anchoring devices on mesh properties has never been examined. METHODS: In 20 sheep, using laparoscopy, we inserted three PhysiomeshTM (large pore, lightweight) and three VentralightTMST (small pore, mediumweight), anchored with ProTackTM, SecurestrapTM or GlubranTM, respectively...

UNLABELLED: The relationship between mesh weight and host tissue reaction has, so far, not been fully investigated. Lightweight meshes (LWM) are thought to give less inflammatory response compared with heavyweight meshes (HWM). The present study is a randomized, controlled, double-blind clinical trial performed in 61 patients who underwent an elective inguinal hernioplasty. The primary outcome of the study was to investigate the relationship between total amount of prosthetic material (polypropylene), immunological reaction, and oxidative stress...

INTRODUCTION AND HYPOTHESIS: Polypropylene is a material that is commonly used to treat pelvic floor conditions such as pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Owing to the nature of complications experienced by some patients implanted with either incontinence or prolapse meshes, the biocompatibility of polypropylene has recently been questioned. This literature review considers the in vivo response to polypropylene following implantation in animal models. The specific areas explored in this review are material selection, impact of anatomical location, and the structure, weight and size of polypropylene mesh types...
