The amino acid sequence of collagen is composed of GlyXaaYaa repeats. A prevailing paradigm maintains that stable collagen triple helices form when (2S)-proline (Pro) or Pro derivatives that prefer the C(γ)-endo ring pucker are in the Xaa position and Pro derivatives that prefer the C(γ)-exo ring pucker are in the Yaa position. Anomalously, an amino acid sequence in an invertebrate collagen has...

The ground truth for cascading failure in power system can only be obtained through a detailed dynamic model involving nonlinear differential and algebraic equations whose solution process is computationally expensive. This has prohibited adoption of such models simulation. To solve this, we propose fast simulation approach based on implicit Backward Euler method (BEM) with stiff decay property...

Several algorithms for adaptive IIR filters parameterized in lattice form can be found in the literature. The salient feature of these structures when compared with the direct form is that ensuring stability is extremely easy. On the other hand, while computing the gradient signals that drive the direct form update algorithms is straightforward, it is not so for the lattice algorithms. This has...

Vector field oriented control (VFOC) of permanent magnet synchronous motor (PMSM) drive requires accurate velocity information sensed by a speed or position sensor attached to the rotor. Nowadays, sensorless control is adopted in many industrial applications for reasons of robustness, cost, cabling and reliability. This paper presents a novel sensorless control strategy and initial rotor positi...

− Accurate knowledge of stator resistance is of utmost importance for correct operation of a number of speed sensorless induction motor control schemes in the low speed region. Since stator resistance inevitably varies with operating conditions, stable and accurate operation at near-zero speed requires an appropriate on-line identification algorithm for the stator resistance. The paper proposes...

We introduce a new consistency condition for neutral social welfare functions, called hyperstability. A social welfare function α selects a complete weak order from a profile PN of linear orders over any finite set of alternatives, given N individuals. Each linear order P in PN generates a linear order over orders of alternatives,called hyper-preference, by means of a preference extension. Henc...

RASSF1A is a tumor suppressor gene that is inactivated by hypermethylation of its promoter region in most types of human cancers. The incidence of spontaneous or induced tumors is significantly higher in Rassf1a(-/-) mice than in wild-type mice, confirming the tumor suppressor function of RASSF1A. RASSF1A promotes apoptosis mainly through its interaction with the proapoptotic serine/threonine S...
