Pairwise particle interactions arise in diverse physical systems ranging from insect swarms to self-assembly of nanoparticles. In the presence of long-range attraction and short-range repulsion, such systems can exhibit bound states. We use linear stability analysis of a ring equilibrium to classify the morphology of patterns in two dimensions. Conditions are identified that assure the well-pos...

the concept of fuzzy soft γ-ring is introduced; and some properties of fuzzy soft γ-rings are given. then the definitions of fuzzy soft γ-ideals are proposed and some of their theories are considered.

We present the discovery of several new regions of interaction between the ejecta and equatorial circumstellar ring of SN1987A, an interaction leading to a much expanded development of the supernova remnant. We also trace the development of the first such “hot spot,” discovered in 1997, back to 1995. Later hot spots seem to have emerged by early 1999. We discuss mechanisms for the long delay be...

A CMOS self-mixing-free RF front-end for direct-conversion receivers is presented, which includes a differential LNA, a ring oscillator, and I/Q double-balanced harmonic mixers and buffers. It operates at 930MHz, achieves 51dB gain and 5.8dB spot noise figure at 100kHz frequency, and consumes 53mW power. A 54dB self-mixing improvement over traditional architecture is obtained. The front-end is ...

We present a new family of pupil masks to control the axial component of the intensity distribution in the focal region of tightly focused light fields. The filters, which consist of a circular clear pupil with a single shaded ring, allow to control the width of the central lobe of the axial spot together with the residual sidelobes energy. The filters can be applied to improve the optical sect...

Using focal stimuli, we successfully recorded oscillatory potentials (OPs) in electroretinograms of the macular regions of 72 normal volunteers. The OPs consisted of three to four wavelets with a mean peak interval of approximately 6.5 msec, consistent with that recorded with conventional full-field stimuli over the entire retina. The changes of amplitude in response to the spot sizes and ring ...

This paper presents micro-OBIC measurements performed at different voltages on two devices protected by narrow field rings. At the surface of device #1, a polyimide layer was deposited during fabrication process. On contrary, passivation removed #2. Thanks to micrometer spatial resolution and spot size carefully focused, small gaps in range 1 μm can be visible OBIC profiles. Thus, variation μ-o...

Spot PIN photodiodes were integrated without any process modifications in a high-voltage 0.18 μm CMOS technology. These are combination of vertical and lateral using the P+ bulk wafer P-type ring at surface as anodes. Devices with N+ cathode N+/N-well compared. A small spot reduces capacitance to 1.47 fF leads 1.07 fF. The light sensitive area these is 707 <sup xmlns:mml="http://www.w3.org/1998...
