We investigated the interactions among visual working memory (VWM), attention, and gaze control in a visual search task that was performed while a color was held in VWM for a concurrent discrimination task. In the search task, participants were required to foveate a cued item within a circular array of colored objects. During the saccade to the target, the array was sometimes rotated so that th...

Micromanipulation of magnetotactic bacteria with a microelectromagnet matrix was demonstrated. Magnetotactic bacteria synthesize a chain of magnetic nanoparticles inside their body to guide their motion in the geomagnetic field. A microelectromagnet matrix consists of two arrays of lithographically patterned wires, one array perpendicular to the other, that are separated and covered by insulati...

We introduce sequentially Sr modules over a commutative graded ring and sequentially Sr simplicial complexes. This generalizes two properties for modules and simplicial complexes: being sequentially Cohen-Macaulay, and satisfying Serre’s condition Sr . In analogy with the sequentially CohenMacaulay property, we show that a simplicial complex is sequentially Sr if and only if its pure i-skeleton...

We study the vortex phase diagram in untwinned YBCO crystals with columnar defects. These randomly distributed defects are expected to induce a "Bose glass" phase of localized vortices exhibiting a vanishing resistance and Meissner effect for magnetic fields H( perpendicular) transverse to the columns. We directly observe the transverse Meissner effect using a Hall probe array. As predicted, th...

One-way recursive wavefield extrapolation and migration has many advantages over other wavefield extrapolation methods. The method can handle complex models and is robust. However, the extrapolation of turning waves is one important omission of one-way wavefield extrapolation In this paper a new hybrid approach for the imaging of steep salt flanks is presented: CFP redatuming is used to redatum...

We demonstrated trapping single neutral Rb atoms in micro traps of an optical ring lattice formed by superposing the +/-l components of the Laguerre-Gaussian mode, and generated by reflecting a single laser beam from a computer controlled spatial light modulator. A single atom in one trap or two atoms with one each in two traps were identified by observing the fluorescence. The trap array loade...

It has been well documented that static face processing is holistic. Faces contain variant (e.g., motion, viewpoint) and invariant (race, sex) features. However, little research focused on whether holistic representations are tolerant of within-person variations. The present study thus investigated faces motion viewpoint variations by manipulating study-test consistency using a complete composi...

There is a large variety of nanomaterials each with unique electronic, optical and sensing properties. However, there is currently no paradigm for integration of different nanomaterials on a single chip in a low-cost high-throughput manner. We present a high throughput integration approach based on spatially controlled dielectrophoresis executed sequentially for each nanomaterial type to realiz...

The popular ESPRIT algorithm provides a computationally eficient approach for direction of arrival (DOA) estimation in situations where the sensor array is composed of two identical translated subarrays. One of the key advantages of ESPRIT is that the subarrays need not be calibrated in order to obtain the DOA estimates. In this paper, the problem of DOA estimation using sensor arrays composed ...

We investigated a method for the angular multiplexing and de-multiplexing of digital holograms recorded in microscope off-axis configuration. The multiplexing has been performed rotating numerically one hologram at different angles and adding all the rotated holograms to obtain a single synthetic digital hologram. Then the digital holograms were de-multiplexed thanks to the unique property of t...
