Identifying and documenting false positive patterns generated by static code analysis tools
… tools are known to flag a large number of false positives. A false positive is a warning message generated by a static code analysis tool for a location in the source code that does not have any known problems. This thesis presents our approach and results in identifying and documenting …

An Assessment of Potential False Positive E.coli Pyroprints in the CPLOP Database
… Although the exact likelihood and cause of this false positive result remains undetermined due to limitations in the sequencing method, its existence questions the accuracy of using pyroprints of the ITS regions as a method of strain classification.</p>

Strip-Miner: Automatic Bug Detection in Large Software Code with Low False Positive Rate
… bug detection, most of them have a high false positive rate when used in practice. This work proposes an approach, named Strip-Miner, that combines simple dependency analysis of code with a data mining technique "frequent itemset mining" to reduce the false positive rate. We adopt a two …

Investigation of mesophilic Aeromonas: response to hydrogen peroxide and role in false-positive Colilert reaction.
… were previously shown to cause production of falsepositive reaction at high cell densities (Edberg et ai., 1988). Similar results were obtained in our study when using fresh Colilert reagents. However, results obtained during this project showed Aeromonas to mediate false-positive reactions at …

Determining the False Positive Rate of a Concussion Battery in Healthy Division I Collegiate Athletes
… <p><strong>Objectives:</strong> (1) evaluate the false positive rate of a clinical concussion assessment battery (BESS, SAC, ImPACT) in a healthy Division I collegiate athlete population and (2) identify trends in pass/fail rates based on months elapsed from baseline testing.</p> …

Psychosocial consequences of false-positive mammography among women attending breast cancer screening. Assessment, prediction, and coping.
… side-effect of breast cancer (BC) screening is a false-positive mammogram among healthy women. That is, finding(s) on a screening mammogram that lead to additional breast examinations but where the woman is eventually considered free from BC. There is evidence of short-term psychosocial …

Reducing False Positive Feigning Classifications on the SIRS among Criminal Defendants with a History of Trauma
… by summing 3 SIRS scales to reduce the number of false positives in a severely traumatized sample. The TI was included as an additional criterion in determining feigning. The TI has not been studied using a forensic sample. Fifty-one adult male criminal defendants were identified as malingering by …

A Quantitative Exploration of Causes of False Positive Single Nucleotide Polymorphisms in Next-Generation Sequencing Data
… error-prone, which can lead to the generation of false positive (FP) SNPs. The traditional approach to SNP discovery is based on mapping reads to a reference sequence. Apart from sequencing errors, which vary in pattern and rate depending on the sequencing platform, the short read lengths that …

The Epidemiology and Health System Impact of Medium-Chain Acyl-CoA Dehydrogenase Deficiency Among Affected Children and Those with False Positive Newborn Screening Results in Ontario, Canada
… among infants diagnosed with MCADD or received a false positive newborn screening result for MCADD from April 2006 through March 2010. Each cohort was compared with screen negative infants by linking to databases encompassing physician visits, emergency department care, and hospitalizations. …

Referrals from Primary Eye Care: An Investigation into their quality, levels of false positives and psychological effect on patients.
… of referrals to the Hospital Eye Service are false positive. Research in areas of healthcare other than ophthalmology has shown that psychological distress can be caused by false positive referrals. The present study aimed to evaluate the quality of referrals to the HES for all ocular …

A comparative analysis of accuracy and sensitivity in semen presumptive testing: ABAcard P30™, RSID Semen™, and Seratec PSA™
… However, presumptive tests can produce false positive results, as these biomarkers may also be present in other bodily fluids. Despite this limitation, some agencies still rely on presumptive test outcomes as a confirmation test for semen in legal proceedings. This study evaluated and …

Identifying predictors of evolutionary dispersion with phylogeographic generalised linear models
… term modelling stochastic noise results in high false positive rates for predictors of spatial diffusion. We further show that the false positive rate can be controlled by including a random effect term, thus allowing unobserved sources of rate variation. Finally, we apply this random effects …

Comparison of Five Different Serological Assays for Determination of Antibody Levels Against Herpes Virus Type 1 and 2
… test results. The groups were negative, low positive, high positive and blind samples. A commercial indirect fluorescent antibody test was compared and was found to be easy to perform and cost effective. The problems with the IFA test is that it has low specificity and high false-positive …

Is Anchoring on Estimates of Severity an Adaptive Heuristic?
… often involves the potential for making either a false positive (preparing for a storm that never arrives) or a false negative error (not preparing for a real storm). Error Management Theory (EMT; Haselton & Buss, 2000) posits that, depending on the uncertain context, people select a …

Nutrition Support and Newborn Screening in the NICU Population: Is There a Link?
… Recent research is revealing the high rate of false-positive screening results for IEMs in the NICU population. No study published to date has specifically studied the possible relationship between nutrition and newborn screening in this population. Objective: It is suspected that NICU infants …

NeuroYara: Learning to Rank for Yara Rules Generation through Deep Language Modeling & Discriminative N-gram Encoding
… machine learning models, Yara rules have a lower false-positive rate and better maintainability of the rules to incorporate new variants of malware. To produce a high-quality rule, one will need extensive experience in reverse engineering and malware analysis. However, it is resource- and …

Development of confirmatory testing strategies for suspect false PRRS-positive reactors in diagnostic serology
… challenged by the occurrence of unexpected false positive results at varying rates. An indirect fluorescent antibody (IFA) test has been commonly employed to confirm or disprove the suspect false positive reactivity in the ELISA. However, the reliability of test results have been often …

Integrating multiple sign types to improve occupancy estimation for inconspicuous species: a case study of American pika in the Pacific Northwest
… to observe a target species when present (false-negative detection error). Use of indirect sign (e.g., scat, tracks) can vastly improve sample size and reduce costs for inconspicuous focal species, but can also introduce additional sources of observation error that may bias estimates of …
