Abstract We consider functions with an asymptotic mean value property, known to characterize harmonicity in Riemannian manifolds and doubling metric measure spaces. show that the strongly amv-harmonic are Hölder continuous for any exponent below one. More generally, we define class of finite amv-norm this belong a fractional Hajłasz–Sobolev space their blow-ups satisfy mean-value property. Furt...

This paper addresses asymptotically (in the number of measurements) minimum variance (AMV) estimators within the class of estimators based on a mixture of real and complexvalued sequence of statistics whose first covariance of its asymptotic distribution is singular. Thanks to two conditions, we extend the standard AMV estimator. We prove that these conditions are satisfied for the estimates of...

The structural phenotype of the movement proteins (MPs) of two representatives of the Bromoviridae, alfalfa mosaic virus (AMV) and brome mosaic virus (BMV), was studied in protoplasts. Immunofluorescence microscopy showed that the MPs of these viruses, for which there has been no evidence of a tubule-guided mechanism, assemble into long tubular structures at the surface of the infected protopla...

We have realized an online gesture recognition platform for hand gestures using 2-channel surface EMG signals acquired from the forearm. Several features, such as AMV, AMV ratio and fourth-order AR model coefficients are extracted from the sEMG signal and the gesture segments are recognized with a Weighted Euclidean Distance Classifier. An above 90% recognition rate has been achieved with only ...

Hakkari ili domates ve biber üretim alanlarında lekeli solgunluk virüsü (Tomato spotted wilt virus, TSWV) yonca mozaik (Alfalfa mosaic AMV)’nün belirlenmesi için yapılan sürveyler 2020 döneminde gerçekleştirilmiştir. Domates sararma, nekroz, şekil bozukluğu simptomu gösteren 184 bitkiden yaprak örneği toplanmıştır. Toplanan örneklerinde TSWV AMV’nin Double antibody sandwich enzyme linked immuno...

The 3'-untranslated regions (3'-UTRs) of the three RNAs of alfalfa mosaic virus (AMV) contain a specific binding site for coat protein (CP) and act as a promoter for minus-strand RNA synthesis by the purified AMV RNA-dependent RNA polymerase (RdRp) in an in vitro assay. Binding of CP to the viral RNAs is required to initiate infection. The sequence of the 3'-terminal 39 nucleotides of AMV RNA 3...

Viruses are among the major agents causing yield loss in pepper production. During 2016-2017, a survey was performed pepperfields to determine of some viruses plants showing virus-like symptoms different provinces Turkey. Plant samples wereassayed using DAS-ELISA with specific antisera for cucumber mosaic virus (CMV), tomato spotted wilt (TSWV), yellow leafcurl (TYLCV), alfalfa (AMV), and mild ...
