Trade-offs in temperature control of fast-ramp RTP systems from an open-loop-input point of view are investigated, i.e., for a given desired temperature recipe a set of lamp command profiles is determined such that the resulting set of measured temperatures approaches the desired recipe as closely as possible. Exact tracking of fast-ramp recipes with rates such as 250 C/sec is usually not possi...

Artificial barriers in Josephson junctions make it possible to change the height and width of the barrier independently. This technique can be realized in high-Tc Josephson junctions using the ramp technique. In this article the fabrication of ramp-type junctions is discussed and the importance of the morphology of the ramp is pointed out. Detailed investigations are described which address the...

Receptor activity modifying proteins (RAMPs) constitute a group of three proteins, designated as RAMP1, 2, and 3, which are able to effect functional changes in some members of the G protein-coupled receptor family. Thus, RAMP1 or RAMP3 can modify the calcitonin receptor (CTR) to also function as a high-affinity amylin receptor-like phenotype. To examine the RAMP/CTR interaction, individual RAM...

PURPOSE To examine the reliability of a perceptually-regulated maximal exercise test (PRETmax) to measure peak oxygen uptake ([Formula: see text]) during handcycle exercise and to compare peak responses to those derived from a ramp-incremented protocol (RAMP). METHODS Twenty recreationally active individuals (14 male, 6 female) completed four trials across a 2-week period, using a randomised,...

Sprint interval training (SIT) elicits comparable long-term adaptations versus continuous exercise training (CEX) including increased maximal oxygen uptake (VO2max) and fat utilization. However, there is limited research examining acute hemodynamic responses to SIT. The aim of this study was to examine hemodynamic responses to low-volume SIT. Active men (n=6, VO2max = 39.8 ± 1.7 mL/kg/min) and ...

In this work, we study the excitation energy for slow changes of the hopping parameter in the Falicov–Kimball model with nonequilibrium dynamical mean-field theory. The excitation energy vanishes algebraically for long ramp times with an exponent that depends on whether the ramp takes place within the metallic phase, within the insulating phase or across the Mott transition line. For ramps with...

OBJECTIVES To evaluate overall joint range of motion of the forelimb in healthy dogs ascending stairs compared with incline slope walking. METHODS Normal canine forelimb kinematics (range of motion, flexion and extension) were compared during ascent of stairs or a ramp, and compared to unimpeded trotting on a flat surface. Eight adult dogs with no evidence of orthopaedic or neurological lamen...

Dynamic traffic management is an important part of the Dutch transport policy. All kinds of measures have been implemented and assessed on the motorway network, such as the motorway traffic management system with speed limits and queue tail warning, ramp metering, variable message signs, dedicated lanes, peak lanes, incident management, etc. In this paper the focus is on ramp metering, which is...
