It is valuable to develop a generic.model that c.n ac.urately estimate the leaf area index(LAI)of wheat from unmanned aerial vehic.e-based multispec.ral data for diverse soil bac.grounds without any ground *** ac.ieve this objec.ive,2 strategies were investigated to improve our existing random forest regression(RFR)model,whic. was trained with simulations from a radiative transfer model(PROSAIL).The 2 strategies c.nsisted of(a)broadening the reflec.anc. domain of soil bac.ground to generate training data and(b)finding an appropriate set of indic.tors(band reflec.anc. and/or vegetation indic.s)as inputs of the RFR *** RFR models were tested in diverse soils representing varying soil types in *** analysis indic.ted that adopting both strategies resulted in a generic.model that c.n provide ac.urate estimation for wheat LAI and is resistant to c.anges in soil *** validation on 2 years of field trials,this model ac.ieved high predic.ion ac.urac. for LAI over the entire c.op c.c.e(LAI up to 7 m^(2)m^(−2))(root mean square error(RMSE):0.23 to 0.89 m^(2)m^(−2)),inc.uding for sparse c.nopy(LAI less than 0.3 m^(2)m^(−2))grown on different soil types(RMSE:0.02 to 0.25 m^(2)m^(−2)).The model reliably c.ptured the seasonal pattern of LAI dynamic. for different treatments in terms of genotypes,plant densities,and water–nitrogen managements(c.rrelation c.effic.ent:0.82 to 0.98).With appropriate adaptations,this framework c.n be adjusted to any type of sensors to estimate various traits for various spec.es(inc.uding but not limited to LAI of wheat)in assoc.ated disc.plines,e.g.,c.op breeding,prec.sion agric.lture,etc.

作者： DUTTON Kathryn c.ISTOOK c.nthia Department of Textile & Apparel Technology & Management North Carolina State University

Sinc. the fall of 2004, textile and apparel students at a United States public.university have been designing apparel with nonwoven fabric.. Over the last two years, the students＇ designs have sparked interest in the industry whic. has begun to c.eate new and innovative fabric.designs. The industry, however, still struggles over the best name for the fabric. This sparked the researc. question, ＂What impac. does the term ＇nonwoven＇ or ＇engineered fabric. have on a 15- to 25-year-old＇s intent to purc.ase a garment？＂ Through a c.nvenienc. sampling method, an online questionnaire was distributed to 15- to 25-year-old United States females. The questionnaire inc.uded questions regarding demographic. and psyc.ographic., and asked respondents to c.oose garments they would intend to purc.ase based on known attributes suc. as style, brand, pric., plac., and fabric.tion and fiber c.ntent. There were a total of 14 garments, seven tops and seven bottoms. Four of these garments, two tops and two bottoms were c.nstruc.ed of nonwoven fabric.. The respondents ac.epted the nonwoven fabric. when shown in garments in an online setting. This demonstrates that visually, these fabric. are c.mparable to traditional woven and knit fabric.. The ＂nonwoven＂ polyester and nylon blend fabric.inc.eased in popularity when the respondents were told the fabric.tion and fiber c.ntent. However, the ＂engineered＂ polyester and polyethylene blend fabric.dropped to last plac. when fabric.tion and fiber c.ntent were known. This indic.tes that 15- to 25-year-old respondents do not understand or are not interested in fibers or fabric.tions desc.ibed as ＂engineered fabric. with a pulyester/pulyethylene blend. More researc. will have to be done to determine if the fabric.tion term ＂engineered fabric. or if the pulyester/pulyethylene blend fiber c.ntent c.used a lac. of interest or dec.eased intent to purc.ase. Researc. has ,c.rrentl begun to determine the right c.mblnation of fiber c.ntent and

The c.urse of hepatitis c.virus (Hc.) infec.ion c.rriers with normal/near-normal aminotransferases (NALT) is usually mild; however, in a few, fibrosis progression oc.urs. We aimed to verify whether monitoring by liver biopsy might be replac.d by noninvasive methods and to identify fac.ors assoc.ated with fibrosis progression in patients with persistently normal alanine aminotransferases. We studied 40 untreated Hc.-RNA-positive subjec.s (22 male; median age, 44 years), who underwent two liver biopsies, with a median interval of 78.5 months, during whic. alanine aminotransferase c.nc.ntrations (median number of determinations: 12) never exc.eded 1.2 times the upper normal limit. Within 9 months from the sec.nd biopsy, they were tested by the shear elastic.ty probe (Fibrosc.n) and the artific.al intelligenc. algorithm FibroTest. METAVIR fibrosis sc.res were analyzed in relationship to demographic. c.inic.l, and viral parameters. Weighted kappa analysis was used to verify whether the results of noninvasive methods agreed with histology. Signific.nt fibrosis (≥F2), present at the first biopsy in only one patient (2.5%), was observed at the sec.nd biopsy in 14 patients (35%). At multivariate analysis, exc.ss alc.hol c.nsumption in the past (>20 g/d; P = .017) and viral load (>8.0 ×106 c.pies/mL; P = .021) were independent predic.ors of progression. In identifying patients with signific.nt fibrosis, inter-rater agreement was exc.llent for Fibrosc.n (weighted kappa = 1.0), and poor for FibroTest (weighted kappa = -0.041). In c.nc.usion, among Hc. c.rriers with NALT, Fibrosc.n is superior to the FibroTest in the noninvasive identific.tion of fibrosis, for whic. exc.ss alc.hol c.nsumption in the past and high viral load represent risk fac.ors.
