Generalized Ribaucour-type surfaces

open access: yes, 2023
In this work we generalize the surfaces studied in [8], we define the generalization of Ribaucour-type surfaces (in short, GRT-surfaces). We obtain present a representation for GRT-surfaces with prescribed Gauss map which depends on two holomorphic functions and a real function l. We give explicit examples of GRT-surfaces.

Pure and mixed ordered monolayers of tetracyano-2,6-naphthoquinodimethane and hexathiapentacene on the Ag(100) surface

open access: yesBeilstein Journal of Nanotechnology, 2019
We report on mixed ordered monolayers of the electron acceptor-type molecule tetracyano-2,6-naphthoquinodimethane (TNAP) and the electron donor-type molecule hexathiapentacene (HTPEN).

Intelligent Variable Structure Control for Speed and Levitation of a Train [PDF]

open access: yesInternational Journal of Railway Research, 2020
In this paper, for the first time a general type-2 fuzzy system (Linguistic or Mamdani) is used to estimate the sliding surface of the sliding mode control (SMC) method for train speed and levitation control.

Simple fibrations in $(1,2)$ -surfaces

open access: yesForum of Mathematics, Sigma, 2023
We introduce the notion of a simple fibration in $(1,2)$ -surfaces – that is, a hypersurface inside a certain weighted projective space bundle over a curve such that the general fibre is a minimal surface of general type with $p_g=2$ and

Pluricanonical Systems On Algebraic Surfaces Of General Type [PDF]

open access: yesJournal of the Mathematical Society of Japan, 1967
After preparing the vanishing theorems, the main Theorem 8 will be proved, that is, it is shown that the m-canonical system is free from base points when \(m\geqq 4\), and the m-canonical map is birational when \(m\geqq 6\).

Numerical solution of the eXtended Pom-Pom model for viscoelastic free surface flows

open access: yes, 2011
In this paper we present a finite difference method for solving two-dimensional viscoelastic unsteady free surface flows governed by the single equation version of the eXtended Pom-Pom (XPP) model. The momentum equations are solved by a projection method

Identification of a system required for the functional surface localization of sugar binding proteins with class III signal peptides in Sulfolobus solfataricus [PDF]

open access: yes, 2007
The hyperthermophilic archaeon Sulfolobus solfataricus contains an unusual large number of sugar binding proteins that are synthesized as precursors with a class III signal peptide.

Downregulation of major histocompatibility complex class I in bovine papillomas [PDF]

open access: yes, 2004
Bovine papillomavirus (BPV) induces papillomas in cattle; in the great majority of cases, these regress due to the host immune response, but they can persist and progress to malignancy.
