The irradiation of protoplanetary discs by central stars is the main heating mechanism for discs, resulting in their flared geometric structure. In a series of papers, we investigate the deep links between 2D self-consistent disc structure and planetary migration in irradiated discs, focusing particularly on those around M stars. In this first paper, we analyse the thermal structure of discs th...

The magnetorotational instability across the dead zone of protoplanetary disks

Context. Recent observations of the X–ray emission from T Tauri stars in the Orion nebula have shown that they undergo frequent outbursts in their X–ray luminosity. These X–ray flares are characterised by increases in luminosity by two orders of magnitude, a typical duration of less than one day, and a significant hardening of the X–ray spectrum. Aims. It is unknown what effect these X–ray flar...

This paper extends the equivalent-input-disturbance (EID) approach to deal with the problem of aperiodic disturbance rejection for a plant with an input dead zone in a repetitivecontrol system so as to improve control performance for the tracking of a periodic signal. Since a dead zone greatly degrades control performance, we apply the EID approach to design a compensator for the nonlinearity b...

This paper presents an improved observer-based robust adaptive control strategy for a class of nonlinear systems that have two features; i. the coupling of unmeasured states and unknown parameters exist at the measured states dynamics, ii. unknown deadzone exists at the system actuation. At first, the bounds of the dead zone parameters are assumed to be known and a suitable control strategy is ...

We describe the electrical manifestations of dead left septal, left and right parietal myocardium and those of biventricular location, reviewing the electrocardiographic signs of the isolated left and right peripheral blocks. We also describe the electrical manifestations of dead myocardium accompanied by a left anterior subdivision block (LASB) and a left posterior subdivision block (LPSB). Th...

in this study, it was aimed to determine the effects of ship dismantling zones on distribution ofheavy metal resistance and level of antibiotic resistance of bacterial isolates from eastern aegean sea coast.thirteen isolates were identified by phylogenetic analysis using 16s rdna sequences which indicated that theisolates belonged to genus bacillus. these strains were investigated in respect of...
