We present the detection of a filament of Lyα emitting galaxies in front of the quasar Q1205-30 at z=3.04 based on deep narrow band imaging and follow-up spectroscopy obtained at the ESO NTT and VLT. We argue that Lyα selection of high redshift galaxies with relatively modest amounts of observing time allows the detection and redshift measurement of galaxies with sufficiently high space densiti...

We find a manifestly N=3 supersymmetric generalization of the four-dimensional Euler-Heisenberg (four-derivative, or F ) part of the Born-Infeld action in light-cone gauge, by using N=3 light-cone superspace. Also at NBI, Univ. of Copenhagen, Denmark, and HCEI, Academy of Sciences, Tomsk, Russia

Talker echoes are one of the influencing factors which need to be addressed during migration of telecommunication towards wideband transmission. A recently carried out talking and listening test (TALT) focusing on wideband echo disturbances is introduced and the results are summarized. The E-Model, a planning tool for telecommunication networks, considers the degradation of the speech quality c...

Under many different conditions activated plasma membrane ion channels give rise to changes in the extracellular concentration of the permeant ion(s). The magnitude and duration of these changes are dependent on the electrochemical driving force(s) on the permeant ion(s) as well as conductance, open time, and channel density. We have modeled the change in the extracellular [K+] due to efflux th...

We find p-brane solutions to the recently proposed IKKT IIB matrix theory for all odd p. We also propose central charges for the p-branes. NBI-HE-97-02 January, 1997

[1] We use narrowband images of Titan obtained in November 1999 to explore the haze vertical structure in Titan’s lower atmosphere. The images were taken with the MountWilson 2.54m telescope using the NASA/GSFC-built Acousto-Optic Imaging Spectrometer. These images were recorded at five wavelengths surrounding the 0.94 mm methane window and are sensitive to a range of altitudes in Titan’s lower...

in state-investor dispute, investor tends that umbrella clause transfers all contractual claims to treaty claims. by contracts, state follows narrow interpretation of this clause. up to ilc articles, establishing of responsibility of state for breach of contract requires tow preconditions. first state is merely responsible when state condoct has been of governmental nature and second is that br...
