Experimental detection of quantum channel capacities [PDF]

open access: yes, 2017
We present an effcient experimental procedure that certifies non vanishing quantum capacities for qubit noisy channels. Our method is based on the use of a fixed bipartite entangled state, where the system qubit is sent to the channel input. A particular

Extraction of tidal channel networks from airborne scanning laser altimetry and aerial photography [PDF]

open access: yes, 2003
The study of the morphodynamics of tidal channel networks is important because of their role in tidal propagation and the evolution of salt-marshes and tidal flats. Channel dimensions range from tens of metres wide and metres deep near the low water mark

Determining tan(beta) in \tau\tau Fusion to SUSY Higgs Bosons at a Photon Collider [PDF]

open access: yes, 2004
We investigate \tau\tau fusion to light h and heavy H and A Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM) at a photon collider as a promising channel for measuring large values of tan(beta).

Using Tau Polarization to Discriminate between SUSY Models and Determine SUSY Parameters at ILC [PDF]

open access: yes, 2004
In many SUSY models the first SUSY signal in the proposed International Linear Collider is expected to come from the pair production of $\tilde\tau_1$, followed by its decay into $\tau$+LSP.

From the principle of dual-channel to the theory of constructing invariant measuring systems

open access: yesФизика волновых процессов и радиотехнические системы, 2020
The article presents the theoretical foundations for constructing invariant and quasi-invariant relative to the disturbing influences of measuring systems. A historical reference which shows the emergence, evolution and spread of methods of the theory of

Mathematical model of process of redundant measurements with uninterrupted influence of measurand on sensing element of sensor [PDF]

open access: yesTekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2011
The paper discusses improvement of accuracy of measurands measurements with the use of measuring channel with nonlinear calibration curve. There is proposed a mathematical model, which describes process of redundant measurements for measuring channel ...

Time Stability of Untethered Electronic Switched MIMO Millimeter-Wave Channel Sounders

open access: yesIEEE Access, 2020
Untethered channel sounders are used to measure mobile radio propagation channels. As high data rate, millimeter-wave and multiple-input multiple output (MIMO) are considered in the next generation communications systems, knowledge of the propagation ...

Picovoltmeter for probing vortex dynamics in a single weak-pinning Corbino channel

open access: yes, 2008
We have developed a picovoltmeter using a Nb dc Superconducting QUantum Interference Device (SQUID) for measuring the flux-flow voltage from a small number of vortices moving through a submicron weak-pinning superconducting channel.

A 16-channel Digital TDC Chip with internal buffering and selective readout for the DIRC Cherenkov counter of the BABAR experiment

open access: yes, 1999
A 16-channel digital TDC chip has been built for the DIRC Cherenkov counter of the BaBar experiment at the SLAC B-factory (Stanford, USA). The binning is 0.5 ns, the conversion time 32 ns and the full-scale 32 mus. The data driven architecture integrates
