BACKGROUND European honeybee (Apis mellifera L.) foragers have a highly developed visual system that is used for navigation. To clarify the neural basis underlying the highly sophisticated visual ability of foragers, we investigated the neural activity pattern of the optic lobes (OLs) in pollen-foragers and re-orienting bees, using the immediate early gene kakusei as a neural activity marker. ...
Globoid cell leukodystrophy (GLD) is a lysosomal storage disease caused by genetic deficiency of galactocerebrosidase (GALC) activity. Failure in catalyzing the degradation of its major substrate, galactocerebroside, in oligodendrocytes (OLs) and Schwann cells leads to death of these myelinating cells, progressive demyelination, and early demise of GLD patients. Transplantation of bone marrow c...
The orthogonal least squares algorithm (OLS) and the support vector regression (SVR) are two popular approaches to choose the structure of the Radial Basis Function Network (RBFN). The former is derived based only on the modelling errors, whilst the latter also on the model complexity. A comparison of the generalization results of networks selected from the OLS and the SVR is presented here usi...
This article provides a matrix representation of the adjustment grid estimator. From this representation, one can invoke the Gauss-Markov theorem to examine the efficiency of ordinary least squares (OLS) and the grid estimator that uses OLS estimates of the adjustments (the ‘‘plug-in’’ grid method). In addition, this matrix representation suggests a generalized least squares version of the grid...
BACKGROUND A previous fibromyalgia (FM) research reports that 20%-47% of diagnosed patients may not meet the study definition of FM 1-2 years after diagnosis. The aim of this study was to gain a better understanding of the progression of FM in a geographically diverse cohort over a 2-year time period. METHODS This cohort study followed 226 subjects recruited online to assess FM and chronic wi...

Fermented mixtures containing fish-offal meal (FOM) and mulberry leaf meal (MLM) were used as protein supplement to partially replace fish meal (FM) in the formulation of diets for the Indian minor carp Labeo bata. The diets included a reference diet (20 % FM), three diets of fermented mixture of FOM and MLM (T2–T4) replacing 50 to 75 % of FM. Formulation of diet with 30 % FOM, 24 % MLM and 5 ...
