Aims. We present the results of an intensive six-month optical continuum reverberation mapping campaign Seyfert 1 galaxy PG 2130+099 at redshift z = 0.063. The ground-based photometric monitoring was conducted on a daily basis with robotic 46 cm telescope WISE observatory located in Israel. Specially designed narrowband filters were used to observe central engine active galactic nucleus (AGN), ...

In this paper, we present an empirical analysis of deregulated electricity prices. We begin by examining the distributional and temporal properties of the price process in a non-parametric framework. This analysis is followed by comparing the forecasting ability of several different statistical models. The findings reveal several characteristics unique to electricity prices including determinis...

Cross-sectional research has indicated that the psychological variables of protective motive theory and normative focus are related to avoidance behaviors around going out or contacting others during COVID-19 pandemic. However, there been no longitudinal investigating whether these predict similar behaviors. The aim this study was examine predicted such immediately after termination pandemic st...

In order to provide a firm identification of the newly discovered Galactic TeV sources, a search for counterparts in a broad band from soft X-ray to soft gamma-rays is crucial as data in these wavebands allow us to distinguish between different types of suggested models (for example leptonic versus hadronic) and, in turn, to disentangle their nature. In this paper, we report the results of a se...

Abstract The conditions under which accreting neutron stars launch radio-emitting jets and/or outflows are still poorly understood. ultracompact X-ray binary X1850–087, located in the globular cluster NGC 6712, is a persistent atoll-type source that has previously shown unusual radio-continuum variability. Here we present results of pilot radio-monitoring program X1850–087 undertaken with Karl ...

BACKGROUND Most cases of hyponatremia--serum sodium concentration ([Na+]) < 135 mEq/l (< 135 mM)--are associated with an elevated plasma arginine vasopressin level. This study investigated the efficacy and tolerability of intravenous conivaptan (YM087), a vasopressin V1A/V2-receptor antagonist, in treating euvolemic and hypervolemic hyponatremia. METHODS Eighty-four hospitalized patients with...

A mathematical model is presented for the lithium intercalation of a single spinel particle as a microelectrode under the stimulus of a cyclic linear potential sweep. The model includes both lithium diffusion within the particle and kinetics at the particle/electrolyte interface. The model is used to predict that peak current densities depend linearly on the scan rate to a certain power with a ...
