On Sums of Dilates [PDF]

open access: yesCombinatorics, Probability and Computing, 2009
For k prime and A a finite set of integers with |A| ≥ 3(k − 1)2(k − 1)! we prove that |A + k · A| ≥ (k + 1)|A| − ⌈k(k + 2)/4⌉ where k · A = {ka: a ∈ A}. We also describe the sets for which equality holds.

Outcomes of Dilation of Recalcitrant Pancreatic Strictures Using a Wire-Guided Cystotome [PDF]

open access: yesClinical Endoscopy, 2021
Background/Aims Pancreatic strictures in chronic pancreatitis are treated using endoscopic retrograde cholangiopancreatography (ERCP) with plastic stent placement. The management of recalcitrant strictures remains a challenge, with the use of a Soehendra

Effects of cyclic shear loads on strength, stiffness and dilation of rock fractures [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2015
Direct shear tests have been performed to determine the peak and residual shear strengths of fractures in sandstone, granite and limestone under cyclic shear loading. The fractures are artificially made in the laboratory by tension inducing and saw-cut

On the Truncated Multidimensional Moment Problems in Cn

open access: yesAxioms, 2022
We consider the problem of finding a (non-negative) measure μ on B(Cn) such that ∫Cnzkdμ(z)=sk, ∀k∈K. Here, K is an arbitrary finite subset of Z+n, which contains (0,…,0), and sk are prescribed complex numbers (we use the usual notations for multi ...

Influence of the systematised co-ordinates inaccuracies on evaluations of deformation indexes of the Earth crust

open access: yesGeodesy and Cartography, 2012
When mapping the area of Lithuania, place-names presented by linguists or given in documents are used. The spelling differences of these names in different sources and over-generalised locations cause the importance of localisation specification and ...
