    AbstractThe aim of this paper is to investigate the structure of radial solutions for a semilinear elliptic equation Δu+(y·∇u)/2+u/(p−1)+|u|p−1u=0, y∈Rn, which is related to forward self-similar solutions of a semilinear parabolic equation vt=Δv+|v|p−1v, (t,x)∈(0,∞)×Rn. We study the existence, uniqueness, and parameter dependency of rapidly decaying solutions with a prescribed number of zeros

    Facilitation of management plan development via spatial classification of areas invaded by alien invasive plant

    Propagule supply and habitat suitability strongly influence the success of invasive alien plants. Thus, an invaded area is likely to have an adequate propagule supply, a suitable habitat, or both for species persistence. Based on this idea, we classified invaded areas into four categories as follows but with establishment still occurring in some cases: Class 1, adequate propagule supply and habitat suitability; Class 2, adequate propagule supply but limited habitat suitability; Class 3, limited propagule supply and adequate habitat suitability; and Class 4, mid- to low-level propagule supply and habitat suitability. We propose a framework for the classification of invaded areas into these four classes and present a case study in which this framework was applied. Classifying target areas in this manner could facilitate more efficient and practical management planning, thereby saving time and resources. We selected the alien shrub Leucaena leucocephala L. (Fabaceae) as a model species, which has invaded the Nakodo-jima Island in the Ogasawara Archipelago of Japan. We developed a species distribution model by incorporating proxy variables for propagule supply and habitat suitability as well as submodels for propagule supply or habitat suitability. Using these submodels, we estimated the levels of propagule supply and habitat suitability in each, and classified the current distribution range appropriately. Using these classifications, land managers could set priorities to concentrate their efforts to efficiently control target species

    A case of WAGR syndrome in association with developmental glaucoma requiring bilateral Baerveldt glaucoma implants and subsequent tube repositioning

    Glaucoma drainage device implantation is efficacious for the treatment of pediatric glaucoma patients when multiple angle surgeries fail. However, tube touching of the corneal endothelium is one of the major postoperative complications to deal with. A 15-month-old male patient with Wilms’ tumor, aniridia, genitourinary anomalies, and mental retardation (WAGR) syndrome was diagnosed with bilateral developmental glaucoma. He underwent Baerveldt glaucoma implant (BGI) surgeries in both eyes after multiple failed trabeculotomies. The tube in his right eye was touching the cornea 15 months after BGI surgery. To avoid corneal endothelium damage, BGI tube repositioning with scleral fixation was performed without serious complications. The bilateral BGI surgeries achieved successful intraocular pressure reduction for over 2 years and tube repositioning with scleral fixation of BGI tube was successful for BGI tube malposition. Although careful attention to intraocular pressure and tube malposition is essential after glaucoma drainage device implantation, especially in pediatric cases, BGI surgery is effective in the management of developmental glaucoma following unsuccessful angle surgeries
