B61 (ephrin-A1), a ligand for eph receptor-protein tyrosine kinases, possesses angiogenic and endothelial cell chemoattractant activity. We report the expression profile of ephrin-A1 during mouse embryogenesis (7.25 to 10.5 days post-coitum (dpc)). Ephrin-A1 expression was first detected in the caudal end of the primitive streak and the developing allantois. At mid head fold stage, ephrin-A1 tr...

Receptor protein-tyrosine phosphatase alpha (RPTP alpha) is a transmembrane member of the family of protein-tyrosine phosphatases (PTPs) that has been implicated in neuronal differentiation in vitro. Here we demonstrate that RPTP alpha is differentially expressed during mouse embryogenesis in a spatio-temporal manner. RPTP alpha expression was detectable in 6 days post coitum (dpc) embryos, but...

Recently, direct power control (DPC) based proportional-integral (PI) controllers have become dominant for doubly fed induction generators (DFIGs) due to its simplicity and good dynamic response. But this strategy gives a high total harmonic distortion (THD) of the voltage large ripple. In paper, new DPC method (called as NDPC-4L-NSVPWM) is proposed on four-level neural space vector pulse width...

Data–driven predictive control (DPC) is becoming an attractive alternative to model as it requires less system knowledge for implementation and reliable data increasingly available in smart engineering systems. Two main approaches exist within DPC: the subspace approach, which estimates prediction matrices (unbiased large data) behavioral, data-enabled uses Hankel (allows optimizing bias/varian...

Many studies have shown that clustered Wireless Sensor Networks (WSNs) a better performance in terms of the balance energy and lifetime. However, due to harsh environment open communication, WSNs are easy be attacked. The selective forwarding attack is one most difficult attacks detected. When malicious sensor node launches attacks, it drops part or all data packets received. In this paper, we ...

Based on the extension of behavioral theory and Fundamental Lemma for Linear Parameter-Varying (LPV) systems, this paper introduces a Data-driven Predictive Control (DPC) scheme capable to ensure reference tracking satisfaction Input-Output (IO) constraints an unknown system under conditions that (i) can be represented in LPV form (ii) informative data-set containing measured IO scheduling traj...

In this paper an iterative technique for sequential mobile power updates in 3G WCDMA networks based on Relaxation Method has been presented. The obtained algorithm is distributed and has the same complexity as the popular DPC (distributed power control) algorithm, which is based on Gauss-Seidel iterations, and which assumes simultaneous power updates for all mobiles that use the same frequency ...

The study made in this paper concerns the use of the direct power control (DPC) technique and the fuzzy logic theory to control a pulse width modulation (PWM) rectifier. These strategies are used to eliminate harmonics currents and consequently to reduce total harmonic distortion (THD) of the line current and improve the power factor. The DPC principle is based on the control of instantaneous a...

A Disjoint Path Cover (DPC for short) of a graph is a set of pairwise (internally) disjoint paths that altogether cover every vertex of the graph. Given a set S of k sources and a set T of k sinks, a many-to-many k-DPC between S and T is a disjoint path cover each of whose paths joins a pair of source and sink. It is classified as paired if each source of S must be joined to a designated sink o...
