DNA Sequence Confidence Estimation

open access: yesGenomics, 1994
A significant bottleneck in the current DNA sequencing process is the manual editing of trace data generated by automated DNA sequencers. This step is used to correct base calls and to associate to each base call a confidence level. The confidence levels are used in the assembly process to determine overlaps and to resolve discrepancies in determining ...

On the Estimation of Synchronous Scramblers in Direct Sequence Spread Spectrum Systems

open access: yesIEEE Access, 2020
In a non-cooperative context, the receiver has no information about communication parameters; therefore, it must perform communication forensics, which is the process of identifying what information it can from the collected data.

Generalized min-max bound-based MRI pulse sequence design framework for wide-range T1 relaxometry: A case study on the tissue specific imaging sequence. [PDF]

open access: yesPLoS ONE, 2017
This paper proposes a new design strategy for optimizing MRI pulse sequences for T1 relaxometry. The design strategy optimizes the pulse sequence parameters to minimize the maximum variance of unbiased T1 estimates over a range of T1 values using the ...

On the reciprocal products of generalized Fibonacci sequences

open access: yesJournal of Inequalities and Applications, 2022
In this paper, we use the properties of error estimation and the analytic method to study the reciprocal products of the bi-periodic Fibonacci sequence, the bi-periodic Lucas sequence, and the mth-order linear recursive sequence.
