Failure-mode index

Search what already failed

A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.

WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

Improving patient identification for advanced cardiac imaging through machine learning-integration of clinical and coronary CT angiography data

Jan Walter Benjamins, Ming Wai Yeung, Teemu Maaniitty et al. · 2021 · International Journal of Cardiology

BACKGROUND: Standard computed tomography angiography (CTA) outputs a myriad of interrelated variables in the evaluation of suspected coronary artery disease (CAD). But an important proportion of obstructive lesions does not cause significant myocardial ischemia. Nowadays, machine learning (ML) allows integration of numerous variables through complex interdependencies that optimize classification and prediction at the individual level. We evaluated ML performance in integrating CTA and clinical variables to identify patients that demonstrate myocardial ischemia through PET and those who ultimat

Limits on the 21 cm Power Spectrum at z = 6.5–7.0 from Murchison Widefield Array Observations

Chuneeta D. Nunhokee, Donald M. Null, Cathryn M. Trott et al. · 2025 · The Astrophysical Journal

Abstract This paper presents the spherically averaged 21 cm power spectrum derived from Epoch of Reionization (EoR) observations conducted with the Murchison Widefield Array (MWA). The analysis uses EoR0-field data, centered at (R.A. = 0 h , decl. = −27 ∘ ), collected between 2013 and 2023. Building on the improved methodology described in C. M. Trott et al. (2024), we incorporate additional data quality control techniques introduced in C. D. Nunhokee (2020). We report the lowest-power-level limits on the EoR power spectrum at redshifts z = 6.5, z = 6.8, and z = 7.0. These power levels, measur

Core–Sheath Nanofibers From a Modified Coaxial Electrospinning for Transdermal Delivery of Finasteride

L L Sun, Yisa Zhao, Xiyu Caomeng et al. · 2026 · ChemistryOpen

Traditional blending electrospinning has a series of issues during implementation, and the corresponding monolithic nanofibers can always be updated through the intentional design of core-sheath nanostructures. In this study, a modified coaxial electrospinning approach was employed to refine the electrospinning process by eliminating abnormal phenomena, while simultaneously imparting core-sheath nanostructures and improved transdermal finasteride (FIN) delivery performance. Using an electrospinnable ethylcellulose (EC) solution containing FIN as the core fluid and an unspinnable polyvinylpyrro

Selective internal radiation therapy (SIRT) for hepatocellular carcinoma (HCC): informing clinical practice for multidisciplinary teams in England

Helen L. Reeves, John Reicher, Georgia Priona et al. · 2022 · Frontline Gastroenterology

Objective: Hepatocellular carcinoma (HCC) deaths are rising alarmingly. Many patients are unsuitable for available therapies. Poor response rates further hamper outcomes for those that are. Selective internal radiation therapy (SIRT) offers hope, although which patients benefit over standard approaches remains unclear. Design/method: As a quality/service improvement, we audited consecutive patients treated with SIRT (2015-2020) by the Newcastle upon Tyne Hospitals National Health Service Foundation Trust HCC multidisciplinary team.

How to get rid of the belief bias: Boosting analytical thinking via pragmatics

Laura Macchi, Francesco Poli, Laura Caravona et al. · 2019 · Europe’s Journal of Psychology

The previous research attempts to reduce the influence of the belief bias on deductive thinking have often been unsuccessful and, when they succeeded, they failed to replicate. In this paper, we propose a new way to see an old problem. Instead of considering the analytical abilities of the respondent, we focus on the communicative characteristics of the experimental task. By changing the pragmatics into play through a subtle manipulation of the instruction of the syllogism problem, we obtained a strong improvement in the accuracy of the performance in both untrained and trained in logic respon

New cycle, same old mistakes? Overlapping vs. discrete generations in long-term recurrent selection

Marlee R. Labroo, Jessica Rutkoski · 2022 · BMC Genomics

BACKGROUND: Recurrent selection is a foundational breeding method for quantitative trait improvement. It typically features rapid breeding cycles that can lead to high rates of genetic gain. Usually, generations are discrete in recurrent selection, which means that breeding candidates are evaluated and considered for selection for only one cycle. Alternately, generations can overlap, with breeding candidates considered for selection as parents for multiple cycles. With recurrent genomic selection but not phenotypic selection, candidates can be re-evaluated by using genomic estimated breeding v

Integrating single-cell RNA-seq datasets with substantial batch effects

Karin Hrovatin, Amir Ali Moinfar, Luke Zappia et al. · 2025 · BMC Genomics

Integration of single-cell RNA-sequencing (scRNA-seq) datasets is standard in scRNA-seq analysis. Nevertheless, current computational methods struggle to harmonize datasets across systems such as species, organoids and primary tissue, or different scRNA-seq protocols, including single-cell and single-nuclei. Conditional variational autoencoders (cVAE) are a popular integration method, however, existing strategies for stronger batch correction have limitations. Increasing the Kullback-Leibler divergence regularization does not improve integration and adversarial learning removes biological sign

BACKGROUND: Chronic obstructive pulmonary disease (COPD) negatively impacts clinical health outcomes, resulting in frequent exacerbations, increased hospitalizations, reduced physical activity, deteriorated quality of life, and diminished self-efficacy. Previous studies demonstrated that a self-management program tailored for adults with COPD improves self-management decisions, resulting in a positive effect on clinical health outcomes. Limitations of these studies include issues regarding heterogeneity among interventions used, patient population characteristics, outcome measures, and longitu

Relaxin Does Not Improve Angiotensin II-Induced Target-Organ Damage

Nadine Haase, Julianna Rugor, Łukasz Przybył et al. · 2014 · PLoS ONE

Relaxin is a corpus-luteum produced protein hormone with vasodilatatory, anti-fibrotic, and angiogenic properties that are opposite to angiotensin (Ang) II. We investigated whether or not relaxin ameliorates Ang II-induced target-organ damage. We used double transgenic rats harboring both human renin and angiotensinogen genes (dTGR) that develop severe hypertension, target-organ damage, and die untreated within 7-8 weeks. Recombinant relaxin at a low (26 μg/kg/d) and a high dose (240 μg/kg/d) was given to 4 week-old dTGR and age-matched Sprague-Dawley rats (SD). Systolic blood pressure increas

Leveraging radiotherapy to improve immunotherapy outcomes: rationale, progress and research priorities

Faith Hartley, Martin A. Ebert, Alistair Cook · 2025 · Clinical & Translational Immunology

The most successful immunotherapies for solid malignancies to date, immune checkpoint inhibitors, target the essential role of T cells in antitumor immunity. However, T-cell dysfunction presents a major hindrance to treatment efficacy, warranting research into combined treatment strategies for improving outcomes. The use of radiotherapy for this purpose has garnered much interest. Preclinical study has established that radiotherapy activates various immune mechanisms to improve T-cell activation, localisation and function within tumors, which improves response to immune checkpoint inhibitors.
