nicu alloy nanowires arrays were embedded into the anodic aluminum oxide (aao) template by ac-pulse electrodeposition. different off-time were used in electrolyte with constant concentration of ni and cu and acidity of 3. the effect of deposition parameters on alloy contents was investigated by studying the microstructure and magnetic properties of as-deposited nicu alloy nanowires. atomic forc...

coni nanowires were deposited by pulsed electrodeposition technique into porous alumina templates. the effect of off time between pulses (toff) and reductive/oxidative time (treduc/oxid) on the microstructure and magnetic properties of the coni nanowires were investigated. maximum coercivity and squareness were obtained for samples fabricated at treduc/oxid= 0.5 ms and toff =400 ms. the coerciv...

CoNi nanowires were deposited by pulsed electrodeposition technique into porous alumina templates. The effect of off time between pulses (toff) and reductive/oxidative time (treduc/oxid) on the microstructure and magnetic properties of the CoNi nanowires were investigated. Maximum coercivity and squareness were obtained for samples fabricated at treduc/oxid= 0.5 ms and toff =400 ms. The coerciv...

  While the effect of changes of stimulus waveform (quasitrapezoidal and rectangular current pulses) on nerve activation is clear, but there is no evidence on the effect of quasitrapezoidal pulses on ionic currents of cellular membrane. In the present study, the effect of depolarizing quasi-trapezoidal current pulses, in comparison with that of depolarizing rectangular current pulses, on firing...

I n the field of neurophysiology, analysis of the majority of neuronal data has been a tiresome task. Many questions and hypotheses posed by investigators in the field have remained unanswered and / or unverified because of inadequate analytical tools. For example, in the course of research at APL by F. F. Hiltz*, the need arose for an inexpensive means of ascertaining time relationships betwee...

• A submitted manuscript is the author's version of the article upon submission and before peer-review. There can be important differences between the submitted version and the official published version of record. People interested in the research are advised to contact the author for the final version of the publication, or visit the DOI to the publisher's website. • The final author version ...

The expectation of a random variable is its average value, where each value is weighted according to the probability that it comes up. The expectation is also called the expected value or the mean of the random variable. For example, suppose we select a student uniformly at random from the class, and let R be the student’s quiz score. Then E [R] is just the class average —the first thing everyo...
