Faster α-expansion via dynamic programming and image partitioning
(2020-07-01)
Image segmentation is the task of assigning a label to each image pixel. When the number of labels is greater than two (multi-label) the segmentation can be modelled as a multi-cut problem in graphs. In the general case, ...
Eigenvalue decay of integral operators generated by power series-like kernels
(ElementZagreb, 2014)
We deduce decay rates for eigenvalues of integral operators generated by power series-like kernels on a subset X of either 'R POT.Q' or 'C POT.Q'. A power series-like kernel is a Mercer kernel having a series expansion ...
Linearizability of the perturbed Burgers equation
(1998-08-01)
We show in this report that the perturbed Burgers equation ut = 2uux + uxx + ε(3 α1u2ux + 3 α2uuxx + 3 α3u2 x + α4uxxx) is equivalent, through a near-identity transformation and up to O(ε), to a linearizable equation if ...
Negative thermal expansion of nanoporous anodic aluminum oxide membranes
(American Institute of Physics, 2019-03)
We have measured the thermal expansion of Ni nanowires (NWs) electrodeposited into self-organized nanoporous amorphous aluminum oxide (AAO) membranes without an Al substrate using X-ray diffraction between 110 K and 350 ...
Role of α2-adrenoceptors in the lateral parabrachial nucleus in the control of body fluid homeostasis
(2014-01-01)
Central α2-adrenoceptors and the pontine lateral parabrachial nucleus (LPBN) are involved in the control of sodium and water intake. Bilateral injections of moxonidine (α2-adrenergic/imidazoline receptor agonist) or ...
