Singularly perturbed vector nonlinear Schrödinger equations (PVNLS) are investigated. Emphasis is placed upon the relation with their restriction: The singularly perturbed scalar nonlinear Schrödinger equation (PNLS) studied in [10]. It turns out that the persistent homoclinic orbit for the PNLS [10] is the only one for the PVNLS, asymptotic to the same saddle.

Multiplicative error models (MEM) became a standard tool for modeling conditional durations of intraday transactions, realized volatilities and trading volumes. The parametric estimation of the corresponding multivariate model, the so-called vector MEM (VMEM), requires a specification of the joint error term distribution, which is due to the lack of multivariate distribution functions on R+ def...

This paper uses a panel structural vector autoregressive (VAR) model to investigate the extent to which global financial conditions, i.e., a global risk-free interest rate and global financial risk, and country spreads contribute to macroeconomic fluctuations in emerging countries. The main findings are: (1) Global financial risk shocks explain about 20 percent of movements both in the country ...

This study examines the impact of oil price volatility on macroeconomic variables of the economy of Pakistan. We employed the Glosten, Jagannathan and Runkle (GJR) and Vector Autoregressive (VAR) models. The outcomes of the GJR model show the symmetric effect of oil price shock on conditional variance. Whereas Impulse Response Functions (IRFs) show the hostile effect on the employment and the o...

With recent improved dense trajectory features (HOG, warped HOF, and warped MBH), we employ two advanced super vector methods, namely Fisher Vector (FV) and soft Vector of Locally Aggregated Descriptors (VLAD-K) to encode them separately. The two individual super vectors are concatenated into a Hybrid Super Vector, and a linear SVM classifier is used to predict labels. We achieve 87.46%1 in ave...

Vector-Meson-Dominance model contribution to π 0 → 4γ is calculated. The result confirms old estimates that this contribution is much smaller than the purely electromagnetic photon spliting graph contribution calculated earlier. In the framework of the Vector-Meson-Dominance (VMD) model, the decay π 0 → 4γ was considered in [1] and [2]. However, no complete evaluation of the decay width can be ...

There have four types of the initial spatial QRS vectors concealed in the normal person: 1. Left-anterior-superior, or 2. Left-anterior-inferior, or 3. Right-anterior-superior, or 4. Right-anterior-inferior The first three directions were the same as the types of initial activity of the normal depolarization process of the interventricular septum revealed by the intra cardiac mapping in dogs re...

Control of the polarization distribution of light allows tailoring the electromagnetic response of plasmonic particles. By rigorously extending the generalized multiparticle Mie theory, we show that focused cylindrical vector beams (CVB) can be used to efficiently excite dark plasmon modes in nanoparticle clusters. In addition to the small radiative damping and large field enhancement associate...

A comparative assessment of two time–domain output–only vector structural identification methods, namely a Vector AutoRegressive (VAR) and a stochastic subspace method, is presented via their application to a laboratory cable–stayed bridge structure. A brief overview of the estimation methods is provided, while model order selection and validation are discussed. The modal frequencies and dampin...
