Understanding the distribution of seafloor sediment using a side-scan sonar is very important to grasp the distribution of seabed resources. This task is traditionally carried out by a skilled human operator. However, with the appearance of Autonomous Underwater Vehicles, automated processing is now needed to tackle the large amount of data produced and to enable on the fly adaptation of the mi...

Using the equivalence between the quantum-mechanical probability density in a quantum billiard and the Poynting vector in the corresponding microwave system, current distributions were studied in a quantum dot like cavity, as well as in a Robnik billiard with λ = 0.4, and an introduced ferrite cylinder. Spatial auto correlation functions for currents and vorticity were studied and compared with...

This paper proposes a cell search method to establish communication links between base stations (BS) and terminals in the dynamic parameter controlled orthogonal frequency and time division multiple access (DPC-OF/TDMA) systems. In the proposed cell search algorithm, a delay profile is first detected by taking auto-correlation between the received signal and its copy delayed by the useful symbo...

In NR-based Access to Unlicensed Spectrum (NR-U) of 5G system, satisfy the rules Occupied Channel Bandwidth (OCB) unlicensed spectrum, channels PRACH and PUCCH have use some sequence repetition mechanisms in frequency domain. These will cause serious cubic metric(CM) problems for these channels, although two types are composed Constant Amplitude Zero Auto-correlation(CAZAC) sequences.. Based on...

BACKGROUND We compared the new Pulsioflex and the Vigileo devices to measure cardiac index (CI) in critically ill patients. Both devices measure CI by pulse-contour analysis. The Pulsioflex device also allows an auto-calibration (not based on thermodilution). METHODS Patients were included if we administered fluids (20 patients), reduced (20 patients), or increased (20 patients) the dose of n...

Chronic rhinosinusitis (CRS) is a frequent chronic condition, which has origins in complex interactions between genetic, immunological and microbial factors. The role of auto-immunity in CRS remains unclear, although recent studies have started to emerge in CRS patient refractory to maximal medical management. We discuss the possible auto-immunity link between CRS and other skin diseases, in pa...

Expressing currents and their fluctuations at the terminals of a multi-probe conductor in terms wave functions carriers injected into Fermi sea provides new insight physics electric currents. This approach helps us to identify two physically different contributions shot noise. In quantum coherent regime, when current is carried by non-overlapping packets, product leads, cross-correlation noise,...
