(SPRINGER, 2005-01)We present a new bit-parallel technique for approximate string matching. We build on two previous techniques. The first one, BPM (Myers, 1999), searches for a pattern of length m in a text of length n permitting k differences ...
-
(Nature Publishing Group, 2019)Vertical profiles of black carbon (BC) and other light-absorbing impurities were measured in seasonal snow and permanent snowfields in the Chilean Andes during Austral winters 2015 and 2016, at 22 sites between latitudes ...
-
(Wiley, 2019)We study the gas accretion and orbital decay of super-massive black hole (SMBH) pairs in the nuclear region of galaxy merger remnants, where a large amount of gas is expected to accumulate. For that purpose, we perform ...
-
(Oxford, 2021)Using parsec scale resolution hydrodynamical adaptive mesh refinement simulations, we have studied the mass transport process throughout a Galactic merger. The aim of such study is to connect both the peaks of mass accretion ...
-
(2007-12-20)We present new H- and K-band spectroscopy of 15 high-luminosity active galactic nuclei (AGNs) at redshifts 2.3Y3.4 obtained with Gemini South.We combined the data with spectra of an additional 29 high-luminosity sources to ...
-
(IOP Publishing., 2011-03-20)We present newH-band spectroscopy for a flux-limited sample of 40 z 4.8 active galactic nuclei, selected from the Sloan Digital Sky Survey. The sample probably contains the most massive active black holes (BHs) at this ...
-
(2005-10-01)We report stellar velocity dispersion measurements for a sample of 28 active galactic nucleus (AGN) host galaxies, including our previous work. Using the mass-dispersion (M.- ) and the fundamental plane relations, ...

(EDP Sciences, 2019)Context. Young planets are expected to cause cavities, spirals, and kinematic perturbations in protostellar disks that may be used to infer their presence. However, a clear detection of still-forming planets embedded within ...

(2002)The classical problem of homogenization of elliptic operators with periodically oscillating coefficients is revisited in this paper. As is well known, the homogenization process in a classical framework is concerned with ...
-
(IOS PRESS, 2005-01)The classical problem of homogenization deals with elliptic operators in periodically oscillating media of small period epsilon>0 and the asymptotic behavior of solution u(epsilon) of boundary value problems associated ...
-
(2005)We consider a periodically heterogeneous and perforated medium filling an open domain of RN . Assuming that the size of the periodicity of the structure and of the holes is O(ε), we study the asymptotic behavior, as ε ...
-
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 1998-02)We consider a second-order elliptic equation in a bounded periodic heterogeneous medium and study the asymptotic behavior of its spectrum, as the structure period goes to zero. We use a new method of Bloch wave homogenization ...
-
(2007)In this Note, we use the Bloch wave method to study the asymptotic behavior of the solution of the Laplace equation in a periodically perforated domain, under a non-homogeneous Neumann condition on the boundary of the ...
-
(SOUTH AFRICAN INST MINING METALLURGY, 2006-03)This work evaluates and characterizes the impact of the support size and mining dilution of a block model in the operation and selection of equipment at an open pit mine. An exploratory analysis and geostatistical modelling ...
-
(IOP Publishing, 2015)Astrophysical research in recent decades has made significant progress thanks to the availability of various N-body simulation techniques. With the rapid development of high-performance computing technologies, modern ...
-
(ACADEMIC PRESS, 2008-07)We say that a square matrix M of order r is a degree matrix of a given graph G if there is a so-called equitable partition of its vertices into r blocks with the following property: For any i and j it holds that a vertex ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2020)Due to the long train marshaling and complex line conditions, the operating modes in heavy haul rail systems frequently change when trains travel. Improper traction or braking operation made by drivers will increase the ...

Blood flow dynamics and arterial wall interaction in a saccular aneurysm model of the basilar artery (PERGAMON-ELSEVIER SCIENCE LTD, 2006-08)Blood flow dynamics under physiologically realistic pulsatile conditions plays an important role in the growth, rupture and surgical treatment of intracranial aneurysms. This paper describes the flow dynamics and arterial ...
-
(JOHN WILEY & SONS LTD, 2008-12-10)Hemodynamics plays an important role in the progression and rupture of cerebral aneurysms. The current work describes the blood flow dynamics and fluid–structure interaction in seven patient-specific models of bifurcating ...
