While the leading-edge serration in owls＇ wing is known to be responsible for low noise gliding and flapping flights, the findings on its aero-acoustic role have been diverse or even controversial. Here we present an experimental study of the morphological effects of leading-edge serrations on aerodynamic force production by utilizing owl-inspired, single-feather, clean and serrated wing models with different serration lengths and spacing, and by combining Particle Image Velocimetry （PIV） and force measurements. Force measurements show that an increase in the length and density of the leading-edge serrations leads to a reduction in the lift coefficient and lift-to-drag ratio at Angles of Attack （AoAs）〈 15° whereas the clean and serrated wings achieve comparable aerodynamic performance at higher AoAs 〉 15°, which owl wings often reach in flight. Furthermore PIV visualization of the flow fluctuations demonstrates that the leading-edge serration-based mechanism is consistent in all serrated wing models in terms of passive control of the laminar-turbulent transition while at AoAs 〉 15° similar suction flow is present at leading edge resulting in a comparable aerodynamic performance to that of the clean wing. Our results indicate the robustness and usefulness of leading-edge serration-inspired devices for aero-acoustic control in biomimetic rotor designs.

Neural Regeneration Research 2024年第5期19卷 949-950页

作者： tetsuya Akaishi Tatsuro Misu Department of Neurology Tohoku UniversitySendaiJapan

In the last decade,a new neurological disease concept known as anti-myelin oligodendrocyte glycoprotein antibody(MOG-IgG)-associated disease(MOGAD)has emerged and is currently one of the most focused research areas in the field of *** is a membrane protein mainly expressed on the surface of oligodendrocytes(Zhou et al.,2006).The exact pathogenic role of MOG-IgG in patients with MOGAD remains unclear;however,MOG-IgG has been suggested to cause tissue alterations and damage MOG-expressing cells(Zhou et al.,2006).The pathogenicity of MOG-IgG is further supported by the observation that only a few patients with acquired central nervous system(CNS)demyelinating syndromes exhibit both anti-aquaporin-4 antibody(AQP4-IgG)and MOG-IgG simultaneously,particularly with clear positivity levels of these antibodies as indicated by a cell-based assay result with a titer≥1:100(Sechi et al.,2021;Banwell et al.,2023).

The Development of the “Monitoring Application for Inappropriate Expressions in Nursing Records”for PsyNACS^©

Lengthening periods of hospitalization, increasing numbers of patients with age-related complications, and a shortage of nursing staff have been of great concern in medical psychiatry in Japan. Under these circumstances, countries such as Japan that face a super-aging society and a decline in the working-age population, have been recommended for use of advanced information and communications technology (ICT) to improve the efficiency of medical treatment and care. This study aims to develop the “Monitoring Application for Inappropriate Expressions in Nursing Records” for using PsyNACS©, which will enable psychiatric nursing plans to harness the advantages of ICT. The functions considered necessary are as follows: 1) identification of users who enter information;2) a necessary database for lists of inappropriate expressions;3) development of a matching function to recommend proper writing input and a warning function;and 4) a management function for an inappropriate expression list database. A demonstration experiment for developing the application in this study was conducted at a specialized psychiatric hospital. To introduce them to the application, nurses and nurse managers were informed about the system developed in this study, and a survey regarding their opinions on the functions of the application was conducted with ten nurse managers. The results were evaluated in terms of usefulness for nursing care, documentation, and the education of nurses from an ethical perspective. This study suggests that matching their input with an inappropriate expression database will allow nurses to record more appropriate expressions. From an ethical perspective, the ability to use appropriate expressions makes records more likely to withstand disclosure requests from patients and their families.

Background and Aims:The clinical introduction of hepcidin25(Hep25)has led to a more detailed understanding of its relationship with ferroportin(FP)and divalent metal transporter1 in primary iron overload syndromes(PIOSs).In 2012,we proposed a classification of PIOSs based on the Hep25/FP system,which consists of prehepatic aceruloplasminemia,hepatic hemochromatosis(HC),and posthepatic FP disease(FP-D).However,in consideration of accumulated evidence on PIOSs,we aimed to renew the ***:We reviewed the 2012 classification and retrospectively renewed it according to new information on ***:Iron-loading anemia was included in PIOSs as a prehepatic form because of the newly discovered erythroferrone-induced suppression of Hep25,and the state of traditional FP-D was remodeled as the BIOIRON *** key molecules responsible for prehepatic PIOSs are low transferrin saturation in aceruloplasminemia and increased erythroferrone production by erythroblasts in iron-loading *** PIOSs comprise four genotypes of HC,in each of which the synthesis of Hep25 is inappropriately reduced in the *** Hep25 synthesis is adequate in posthepatic PIOSs;however,two mutant FP molecules may resist Hep25 differently,resulting in SLC40A1-HC and FP-D,*** phenotypes are diagnosed using laboratory tests,including circulating Hep25,followed by suitable *** sequencing of the candidate genes may be outsourced to gene centers when *** kits for the prevalent mutations,such as C282Y,may be the first choice for a genetic analysis of HC in ***:The revised classification may be useful worldwide.
