After bilateral ablation of the medial precruciate cortex in dogs and cats, or dorsolateral prefrontal cortex in monkeys, the animals approach the source of the conditional stimulus (CS) indicating availability of food either before or instead of approaching the food itself. This behavior is designated the "magnet reaction". It is particularly evident when the source of the CS is located in a d...

2014 A pulsed source for Cs-ions has been constructed as part of a sputter ion source in Hortig geometry. A beam of Cs-ions is extracted from a tungsten surface ionizer and bunched into pulses a few ns wide by a combination of velocity and path-of-flight modulation. It is expected that such a beam will produce intense pulses of negative ions having pulse widths in the ns range. REVUE DE PHYSIQU...

The SPIDER experiment, operated at the Neutral Beam Test Facility of Consorzio RFX, Padua, hosts prototype H-/D- ion source for ITER neutral beam injectors. maximization current extracted from and minimization amount co-extracted electrons are among most relevant targets to accomplish. Cavity Ring-Down Spectroscopy diagnostic measures negative density in close acceleration system, so as have fe...

We discuss welfare and various policy interventions for mixed ICT markets where firms use either ‘open source’ (OS) or ‘closed source’ (CS) business models. We find that the existence of OS business models improves social welfare compared to all-CS industries by letting firms share costs and avoid duplication. However, code sharing also establishes a de facto quality-cartel that suppresses OS f...

Effective production of hydrogen negative ions (H−) is one of the important issues in high power neutral beam injection (NBI) for fusion experimental devices. Cesium (Cs) vapor is seeded in the H− sources to enhance the H− production rate, which depends strongly on the amount of Cs inside the source. On the other hand, oxygen and water attenuate the production rate. In order to investigate the ...

For a sound field observed on a sensor array, compressive sensing (CS) reconstructs the direction of arrival (DOA) of multiple sources using a sparsity constraint. The DOA estimation is posed as an underdetermined problem by expressing the acoustic pressure at each sensor as a phase-lagged superposition of source amplitudes at all hypothetical DOAs. Regularizing with an ℓ1-norm constraint rende...

A RIKEN 18 GHz electron cyclotron resonance ion source (18 GHz ECRIS) is used as an external ion source at the Radioactive Ion Beam Factory (RIBF) accelerator complex to produce an intense beam of medium-mass heavy ions (e.g., Ca and Ar). In most components that comprise the RIBF, the control systems (CSs) are integrated by the Experimental Physics and Industrial Control System (EPICS). On the ...

For a sound field observed on a sensor array, compressive sensing (CS) reconstructs the directionof-arrivals (DOAs) of multiple sources using a sparsity constraint. The DOA estimation is posed as an underdetermined problem expressing the acoustic pressure at each sensor as a phase-lagged superposition of source amplitudes at all hypothetical DOAs. Regularizing with an l1-norm constraint renders...

In the absence of contrary information, it would seem prudent for competitors to attribute to their opposition the same level of rationality they attribute to themselves. In the context of a simple but interesting Cs (command, control, and communication) model presented in Ref. 131, a method is proposed for incorporating symmetrical rationality without resorting to the general multistage game f...
