objective(s): use of a positron emission tomography (pet)/single-photonemission computed tomography (spect) system facilitates the simultaneousacquisition of images with fluorine-18 fluorodeoxyglucose (18f-fdg) andtechnetium (99mtc)-tetrofosmin. however, 18f has a short half-life, and 511kev compton-scattered photons are detected in the 99mtc energy window.therefore, in this study, we aimed to ...

Digital subscriber lines (DSLs) are fundamentally limited by crosstalk. The case where all crosstalk is from the same type of DSL has been studied over the years and accurate models have been standardized. However, crosstalk from multiple different types of DSLs is a relatively new area of study and models of summing mixed crosstalk have only recently been postulated. As more and more types of ...

In this paper we address the problem of crosstalk reduction for autostereoscopic displays. Crosstalk refers to the perception of one or more unwanted views in addition to the desired one. Specifically, the proposed approach consists of three different stages: a crosstalk measurement stage, where the crosstalk is modeled, a filter design stage, based on the results obtained out of the measuremen...

An analytical expression for the mode coupling coefficient in homogeneous trench-assisted multi-core fibers is derived, which has a simple relationship with the one in normal step-index structures. The amount of inter-core crosstalk reduction (in dB) with trench-assisted structures compared to the one with normal step-index structures can then be written by a simple expression. Comparison with ...

A dynamical model for multichannel amplification by near-traveling-wave optical amplifiers is presented, and results on crosstalk induced by either amplitude modulation or frequency modulation are given. The mechanisms influencing the crosstalk are especially the residual facet reflectivities and the detuning of the channels relative to the amplifier Fabry-Perot spectrum. Calculations of worst ...

Electromagnetic crosstalk poses a serious problem in advanced serial communication modules. This paper focuses on the primary sources of crosstalk penalty in a 2.5 Gb/s optic transceiver and a 1OGb/s optic transponder. A novel method to quantify the crosstalk penalty by observing a receiver's bit-error-ratio (BER) versus transmitter to receiver signal phase is proposed. A coupled microstrip tra...

The crosstalk characteristic is a key factor that affects the pickup actuator dynamic property and consequently the accuracy of reading and writing operation in the future ultra-high density optical storage systems. In this paper, the actuator spatial magnetic field distribution model is first established. Then the crosstalk movement phenomenon of the actuator is analyzed and simulated in CST s...

The inter-wire spacing in a VLSI chip becomes closer as the VLSI fabrication technology rapidly evolves. Accordingly, it becomes important to consider crosstalk caused by the coupling capacitance between adjacent wires in the layout design for the fast and safe VLSI circuits. The upper bounds of allowable crosstalks, called crosstalk constraint, are usually given for each net in the design spec...

Gene regulation relies on the specificity of transcription factor (TF)-DNA interactions. Limited specificity may lead to crosstalk: a regulatory state in which a gene is either incorrectly activated due to noncognate TF-DNA interactions or remains erroneously inactive. As each TF can have numerous interactions with noncognate cis-regulatory elements, crosstalk is inherently a global problem, ye...

Crosstalk noise is due to the effect of the transition of a signal called aggressor on its neighbours called victims. A lot of analytical methods propose to evaluate crosstalk noise without taking into account the fact that all the neighbour signals are not making a transition in the same time. Thus, the crosstalk noise is overestimated. We propose a novel approach to evaluate crosstalk effects...
