Given a linear multivariate regression problem with block sparsity structure on the regression matrix, one popular approach for estimating its unknown parameter is blockregularization, where the sparsity of different blocks of the regression matrix is promoted by penalizing their `∞-norms. The main goal of this work is to characterize the properties of this estimator under high-dimensional scal...

The commonly used one step methods and linear multi-step methods all have a global error that is of the same order as the local truncation error. In fact, this is true of the entire class of general linear methods. In practice, this means that the order of the method is typically defined solely by order conditions which are derived by studying the local truncation error. In this work we investi...

This paper presents an experimental investigation on Glued Laminated Timber (GLT) beams made with two tropical woods species, for structural purposes. Two wood species different density and under-exploited were chosen. These are Dacryodes buettneri (Ozigo) Pterocarpus osun (Padouk), Ozigo was taken as a reference species. A Phenol Resorcinol Formaldehyde (PRF) adhesive resistant to harsh enviro...

Glutamate transporters play a critical role in the maintenance of low extracellular concentrations of glutamate, which prevents the overactivation of post-synaptic glutamate receptors. Four distinct glutamate transporters, GLAST/EAAT1, GLT-1/EAAT2, EAAC1/EAAT3 and EAAT4, are distributed in the molecular layer of the cerebellum, especially near glutamatergic synapses in Purkinje cells (PCs). Thi...

Cervical nerve root injury commonly leads to radicular pain. Normal sensation relies on regulation of extracellular glutamate in the spinal cord by glutamate transporters. The goal of this study was to define the temporal response of spinal glutamate transporters (glial glutamate transporter 1 [GLT-1], glutamate-aspartate transporter [GLAST], and excitatory amino acid carrier 1) following nerve...
