IndustReal: A Dataset for Procedure Step Recognition Handling Execution Errors in Egocentric Videos in an Industrial-Like Setting
Although action recognition for procedural tasks has received notable
attention, it has a fundamental flaw in that no measure of success for actions
is provided. This limits the applicability of such systems especially within
the industrial domain, since the outcome of procedural actions is often
significantly more important than the mere execution. To address this
limitation, we define the novel task of procedure step recognition (PSR),
focusing on recognizing the correct completion and order of procedural steps.
Alongside the new task, we also present the multi-modal IndustReal dataset.
Unlike currently available datasets, IndustReal contains procedural errors
(such as omissions) as well as execution errors. A significant part of these
errors are exclusively present in the validation and test sets, making
IndustReal suitable to evaluate robustness of algorithms to new, unseen
mistakes. Additionally, to encourage reproducibility and allow for scalable
approaches trained on synthetic data, the 3D models of all parts are publicly
available. Annotations and benchmark performance are provided for action
recognition and assembly state detection, as well as the new PSR task.

Measurement of Z0 decays to hadrons, and a precise determination of the number of neutrino species
We have made a precise measurement of the cross section for e+e--->Z0-->hadrons with the L3 detector at LEP, covering the range from 88.28 to 95.04 GeV. From a fit to the Z0 mass, total width, and the hadronic cross section to be MZ0=91.160 +/- 0.024 (experiment) +/-0.030(LEP) GeV, [Gamma]Z0=2.539+/-0.054 GeV, and [sigma]h(MZ0)=29.5+/-0.7 nb. We also used the fit to the Z0 peak cross section and the width todetermine [Gamma]invisible=0.548+/-0.029 GeV, which corresponds to 3.29+/-0.17 species of light neutrinos. The possibility of four or more neutrino flavors is thus ruled out at the 4[sigma] confidence level.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28683/3/0000500.pd
A measurement of the Z0 leptonic partial widths and the vector and axial vector coupling constants
We have measured the partial widths of the Z0 into lepton pairs, and the forward-backward charge asymmetry for the process e+e--->[mu]+[mu]- using the L3 detector at LEP. We obtain an average [Gamma]ll of 83.0+/-2.1+/-1.1 MeV.From this result and the asymmetry measurement, we extract the values of the vector and axial vector couplings of the Z0 to leptons: grmv=-0.066-0.027+0.046 and grmA= -0.495-0.007+0.007.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28666/3/0000483.pd
