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.

Clinical Implications of ChatGPT-assisted Multimodal Pre-operative Assessment in Elderly Pertrochanteric Fracture Patients: An Exploratory Study.

Noda, Takahara, Hayashi et al. · 2026 · Journal of orthopaedic case reports

Given the high mortality associated with femoral trochanteric fractures, reliable pre-operative estimation of post-operative death risk is essential. Commonly used scoring systems demonstrate only moderate predictive ability, largely…

Searching for dynamical fermion effects in UKQCD simulations

Chris Allton · 2001 · arXiv

We present recent results from the UKQCD collaboration's dynamical QCD simulations. This data has fixed lattice spacing but varying dynamical quark mass. We concentrate on searching for an unquenching signal in the mesonic mass spectrum where we do not find a significant effect at the quark masses considered.

Problems parameterized by treewidth tractable in single exponential time: a logical approach

Michał Pilipczuk · 2011 · arXiv

We introduce a variant of modal logic, dubbed EXISTENTIAL COUNTING MODAL LOGIC (ECML), which captures a vast majority of problems known to be tractable in single exponential time when parameterized by treewidth. It appears that all these results can be subsumed by the theorem that model checking of ECML admits an algorithm with such complexity. We extend ECML by adding connectivity requirements and, using the Cut&Count technique introduced by Cygan et al. [4], prove that problems expressible in the extension are also tractable in single exponential time when parameterized by treewidth; however

Intrinsic energy of Lemaître-Tolman-Bondi models and cosmological implications

Ramon Lapiedra, Juan Antonio Morales-Lladosa · 2013 · arXiv

Recently, some Lema{î}tre-Tolman-Bondi metrics have been considered as models alternative to the dark energy within the Friedmann-Lema{î}tre-Robertson-Walker universes. The vanishing of the intrinsic energy of these metrics is examined since such a vanishing, in the present case and in general, could be interpreted as a necessary condition to consider the possibility of the quantum creation of a metric. More specifically, this vanishing is examined in the particular case where the Lema{î}tre-Tolman-Bondi metrics behave asymptotically like a Friedmann-Lema{î}tre-Robertson-Walker universe. Final

Intrinsic Redshifts in QSOs Near NGC 6212

M. B. Bell, S. P. Comeau · 2003 · arXiv

The high number of QSOs around NGC 6212 allows a correlation analysis to be carried out between their redshift distribution and the redshift distributions predicted by intrinsic redshift models. We find no correlation between the QSO redshift distribution and the intrinsic redshifts predicted by Karlsson's log(1+z) = 0.089 relation. However, we find that the QSO redshift distribution is correlated with the intrinsic redshifts predicted by the relation z_{iQ} = 0.62[N-0.1M_{N}], for N = 3. We also find evidence that the observed redshifts of the QSOs contain a small cosmological redshift compon
