Breaking the $f+1$ Barrier: Executing Payment Transactions in Parallel with Less than $f+1$ Validations [PDF]

open access: yesarXiv, 2023
We consider the problem of supporting payment transactions in an asynchronous system in which up to $f$ validators are subject to Byzantine failures under the control of an adaptive adversary. It was shown that this problem can be solved without consensus by using byzantine quorum systems (requiring at least $2f+1$ validations per transaction in ...

Comparing Two Subjective Rating Scales Assessing Cognitive Load During Technology-Enhanced STEM Laboratory Courses

open access: yesFrontiers in Education, 2021
Cognitive load theory is considered universally applicable to all kinds of learning scenarios. However, instead of a universal method for measuring cognitive load that suits different learning contexts or target groups, there is a great variety of ...

Validation of association

open access: yesInsurance: Mathematics and Economics, 2020
Recognizing, quantifying and visualizing associations between two variables is increasingly important. This paper investigates how a new function-valued measure of dependence, the quantile dependence function, can be used to construct tests for independence and to provide an easily interpretable diagnostic plot of existing departures from the null ...

Highly multiplexed digital PCR assay for simultaneous quantification of variant allele frequencies and copy number alterations of KRAS and GNAS in pancreatic cancer precursors

open access: yesMolecular Oncology, EarlyView.
Combining melting curve analysis enhances the multiplexing capability of digital PCR. Here, we developed a 14‐plex assay to simultaneously measure single nucleotide mutations and amplifications of KRAS and GNAS, which are common driver genes in pancreatic cancer precursors. This assay accurately quantified variant allele frequencies in clinical samples

Ecological Validity of Performance Validity Testing [PDF]

open access: yesArchives of Clinical Neuropsychology, 2014
Performance validity tests (PVTs) have been shown to relate to neuropsychological performance, but no studies have looked at the ecological validity of these measures. Data from 131 veterans with a history of mild traumatic brain injury from a multicenter Veterans Administration consortium were examined to determine the relation between scores on a ...

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

open access: yesMolecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

Correlation between scores obtained by medical students in various educational courses and Basic Sciences and Pre-internship Comprehensive Exams

open access: yesDevelopment Strategies in Medical Education, 2016
Introduction: Predictive validity is one of important characteristics of a test; it means that what extent a test predicts scores of criterion test. This type of validity can be obtained through determining correlation between scores of two tests.
