A common approach for classifying shock graphs is to use a dissimilarity measure on graphs and a distance based classifier. In this paper, we propose the use of kernel functions for data mining problems on shock graphs. The first contribution of the paper is to extend the class of graph kernel by proposing kernels based on bag of paths. Then, we propose a methodology for using these kernels for...

In this work, we propose an analysis of the global market for crude oil based on a revised version Structural Vector Autoregressive (SVAR) model introduced by Kilian and Murphy (2014). On respect, replace proxy above-ground inventories with futures-spot spread. The latter is defined as percent deviation futures price from spot it represents measure convenience yield but expressed opposite sign....

We study the multifaceted effects and persistence of trade policy shocks on financial markets in a structural vector autoregression. The model is identified via event day heteroskedasticity. find that restrictive US affect international stock prices heterogeneously, but generally negatively, increasing market uncertainty, lowering interest rates, leading to an appreciation US-Dollar. are signif...

according to amount of oil seeds import in iran are more than 80% of domestic needs, in this study, import comparative advantage in soybeans using rca and rsca index is calculated in 1961-2008 periods for iran and ten important importer countries. iran’s competition state is investigated. also long run relation between production and import comparative advantage index is estimated using johanse...

A selectable marker for transformation was constructed by transcriptional fusion of a Ustilago maydis heat shock gene promoter with the hygromycin B phosphotransferase gene of Escherichia coli. U. maydis was transformed to hygromycin B resistance by polyethylene glycol-induced fusion of spheroplasts following exposure to plasmid DNA that carried the marker gene. Transformation frequencies of 50...

The interaction of high-velocity neutron stars with the interstellar medium produces bow shock nebulae, where the relativistic neutron star wind is confined by ram pressure. We present multi-wavelength observations of the Guitar Nebula, including narrow-band Hα imaging with HST/WFPC2, which resolves the head of the bow shock. The HST observations are used to fit for the inclination of the pulsa...

In extensive oil-related literature, less attention has been paid to Asia and particularly little evidence is known for oil-refining countries. This paper examines how the economy of an country reacts oil price shock performs cross-country comparisons with oil-exporting oil-importing Singapore (oil refiner), Japan importer), Malaysia exporter) are analysed through a structural vector autoregres...

This paper explores the impact on macroeconomy for certain OECD economies exposed to COVID-19 pandemic shock. The analysis employs a panel of countries, spanning period March 2020 January 2021. It also uses two proxies shocks: i) total confirmed incidences/cases and ii) deaths while using Bayesian Panel Vector Autoregressive (BPVAR) method. findings document that shock exerts strong negative ef...

This paper considers an improvement in capital embodied technology which only production units that adapt to new knowledge can utilize. This innovation is distinct from a decline in capital goods price which can be utilized by all production units. A simple firm dynamics model is used to show that such an innovation shock enhances reallocation, whereas a shock lowering capital goods price reduc...

Examinations of the magnetohydrodynamic (MHD) equations across a bow shock are presented. These equations are written in the familiar Rankine–Hugoniot set, and an exact solution to this set is given which involves the upstream magnetosonic Mach number, plasma , polytropic index, and B v , as a function of position along the shock surface. The asymptotic Mach cone angle of the shock surface is a...
