New speckle holographic images of the T Tauri infrared companion (T Tauri IRC; T Tauri S) reveal it to be a double system with a sky-projected separation of 0&farcs;05, corresponding to a linear distance of 7 AU. The presence of this third star may account for the relative paucity of dust surrounding the IRC.

Plasma levels of progesterone and corticoids were determined in eight sows prior to, during and following parturition. A statistically significant diurnal variation was observed with morning samples having a higher level of corticoids. Progesterone levels decreased through the last day of gestation to a low level at day 1 postpartum. Mean corticoid levels increased during the last 24-hr. prepar...

The reaction force and the electronic flux, first proposed by Toro-Labbé et al. (J Phys Chem A 103:4398, 1999) have been expressed by the existing conceptual DFT apparatus. The critical points (extremes) of the chemical potential, global hardness and softness have been identified by means of the existing and computable energy derivatives: the Hellman-Feynman force, nuclear reactivity and nuclea...

In a fluid out of equilibrium, the fluctuation-dissipation theorem (FDT) is usually violated. Using molecular dynamics simulations, we study in detail the relationship between correlation and response functions in a fluid driven into a stationary nonequilibrium state. Both the high temperature fluid state and the low temperature glassy state are investigated. In the glassy state, the violation ...

Subjects with life-threatening asthma (LTA) have reported decreased sensitivity to inspiratory resistive (R) loads. It is unknown if decreased sensitivity is specific for inspiratory R loads, other types of respiratory loads, or a general deficit affecting sensory modalities. This study hypothesized that impairment is specific to respiratory stimuli. This study tested perceptual sensitivity of ...

In the stadium structure, the significant dynamic responses such as resonance or similar behavior can be occurred by spectator rhythmical activities. Thus, accurate analysis and precise investigation of stadium structure that is subjected to dynamic loads are required for practical design and serviceability check of stadium structures. Moreover, it is desirable to measure and analyze the dynami...

This paper presents a two-stage adaptive robust optimization framework for day-ahead energy and intra-day flexibility self-scheduling of technical virtual power plant (TVPP). The TVPP exploits diverse distributed resources’ (DERs) capabilities in order to offer services wholesale market as well preserving the distribution network's operational constraints presence DER uncertainties. aims at max...

— Developing states with limited regulatory capacity might benefit from a responsive approach to regulation. Responsive regulation is a democratic ideal, incorporating notions of deliberative democracy and restorative justice. Responsive regulation conducted by regulatory networks of governmental and non-governmental actors allows for networking around capacity deficits. NGOs play a vital role ...

Motivated by the recent trend of onshoring/backshoring, this paper studies a two-stage sourcing game where competing firms may choose between sourcing internationally (call this efficient sourcing strategy due to low production cost) and sourcing domestically (call this responsive sourcing strategy due to short lead time). We first characterize the equilibrium of the sourcing game. Then we exam...
