Neural correlates of non-retinotopic motion integration

Michael Herzog, Gijs Plomp, Yvonne Evelina Thunell

Under normal viewing conditions, due to the motion of objects and to eye movements, the retinotopic representation of the environment constantly changes. Yet we perceive the world as stable, and we easily keep track of moving objects. Here, we investigated ...

The continuum intensity as a function of magnetic field II. Local magnetic flux and convective flows

Philipp Kobel

Context. To deepen our understanding of the role of small-scale magnetic fields in active regions (ARs) and in the quiet Sun (QS) on the solar irradiance, it is fundamental to investigate the physical processes underlying their continuum brightness. Previo ...

Motion and tilt aftereffects occur largely in retinal, not in object coordinates

Michael Herzog, Marco Boi

A variety of aftereffects was found to be processed non-retinotopically. Other studies failed to ﬁnd non-retinotopic aftereffects. These experiments relied on paradigms involving eye movements. We have developed a paradigm, based on the Ternus–Pikler displ ...

Every graph admits an unambiguous bold drawing

János Pach

Let r and w be a fixed positive numbers, w < r. In a bold drawing of a graph, every vertex is represented by a disk of radius r, and every edge by a narrow rectangle of width w. We solve a problem of van Kreveld [K09] by showing that every graph admits a b ...

Experimental Contribution to the Mechanics of Herringbone Grooved Journal Air Bearings

Ivan Ognjanovic

Gas Lubricated Herringbone Grooved Journal Bearings (HGJB) have long been used in equipment such as navigation systems, optical scanners for laser printers and high speed cameras and disk spindle for flyhead testers. All such applications are characterized ...

VLT adaptive optics search for luminous substructures in the lens galaxy towards SDSS J0924+0219

Frédéric Courbin, Georges Meylan, Malte Tewes, Nicolas Cantale

The anomalous flux ratios between quasar images are suspected of being caused by substructures in lens galaxies. We present new deep and high-resolution H and Ks imaging of the strongly lensed quasar SDSS J0924+0219 obtained using the ESO VLT with adaptive ...

Current-induced vortex dynamics and pinning potentials probed by homodyne detection

Using a homodyne detection scheme, we show that we can determine the polarity and chirality of a magnetic vortex in an asymmetric magnetic disk as well as the resonance frequency and phase shift of the dynamic vortex gyration excited by a spin-polarized cu ...

1.38-μm mode-locked Raman fiber laser pumped by semiconductor disk laser

Elyahou Kapon, Alexandru Mereuta, Alexei Sirbu

A mode-locked Raman fiber laser pumped by 1.3 mu m semiconductor disk laser is demonstrated. Direct Watt-level core-pumping of the single-mode fiber Raman lasers and amplifiers with low-noise disk lasers is demonstrated to represent a highly practical solu ...

Raman fiber laser pumped by a semiconductor disk laser and mode locked by a semiconductor saturable absorber mirror

Elyahou Kapon, Alexei Sirbu

A 1.6 mu m mode-locked Raman fiber laser pumped by a 1480 nm semiconductor disk laser is demonstrated. Watt-level core pumping of the single-mode fiber Raman lasers with low-noise disk lasers together with semiconductor saturable absorber mirror mode locki ...
