We explore the rotation and activity of very low mass (VLM) objects by means of a photometric variability study. Our targets in the vicinity of ǫOri belong to the Ori OB1b population in the Orion star-forming complex. In this region we selected 143 VLM stars and brown dwarfs (BDs), whose photometry in RIJHK is consistent with membership of the young population. The variability of these objects ...

We previously described the physicochemical characteristics (particle size, adsorbed polynuclear aromatic hydrocarbons [PAHs], oxygen, and metal content) of butadiene soot (BDS) nanoparticles generated during incomplete combustion of the high-volume industrial petrochemical, 1,3-butadiene. We also demonstrated localization of BDS-delivered PAHs to lipid droplets of murine and human respiratory ...

Binaural auditory neurons exhibit "best delays" (BDs): They are maximally activated at certain acoustic delays between sounds at the two ears and thereby signal spatial sound location. BDs arise from delays internal to the auditory system, but their source is controversial. According to the classic Jeffress model, they reflect pure time delays generated by differences in axonal length between t...

Benefits from the modernized US Global Positioning System (GPS), the revitalized Russian GLObal NAvigation Satellite System (GLONASS), and the newly-developed Chinese BeiDou Navigation Satellite System (BDS) and European Galileo, multi-constellation Global Navigation Satellite System (GNSS) has emerged as a powerful tool not only in positioning, navigation, and timing (PNT), but also in remote ...

First evidences of IR excess and disk mass accretion (strong Hα emission) around brown dwarfs seem to indicate the existence of circumstellar disks around these sub-stellar objects. Nothing is known at the present time about outflows which potentially might be launched from brown dwarfs, although jets are typically associated with the accretion in standard T Tauri star disks. In this paper we c...

Aiming at the requirement of the autonomous time synchronization in BeiDou Navigation Satellite System (BDS), an algorithm for inter-satellite autonomous time synchronization and ranging is proposed. Based on the establishment of the inter-satellite link length model of the BDS, a series of simulation has been carried out through the use of STK (Satellite Tool Kit), which includes the simulatio...

The problem of fair distribution of available bandwidth among traffic flows or aggregates remains an essential issue in computer networks. This paper introduces a novel approach, called the Exact Bandwidth Distribution Scheme (X-BDS), for dynamic and fair distribution of available bandwidth among individual flows. In this approach, the edge routers keep per-flow information, while the core rout...

Results of broadband dielectric spectroscopy (BDS) in Saccharomyces cerevisiae (baker's yeast), in situ as the function of pressure are presented. They show a clear evidence of a threshold to the new pattern of the pressure evolution of the static dielectric permittivity and DC electric conductivity already for Pt  ≈ 200MPa at T = 5 oC and Pt  ≈ 300MPa at T = 25 oC. BDS monitoring versus pressu...
