An accident that need not have happened

If it may have happened before, it happened, but not necessarily before

Temporal uncertainty in raw data can impede the inference of temporal and causal relationships between events and compromise the output of data-to-text NLG systems. In this paper, we introduce a framework to reason with and represent temporal uncertainty from the raw data to the generated text, in order to provide a faithful picture to the user of a particular situation. The model is grounded i...

Dynamical System State Need not Have Spectrum

A classification of LSI polynomials into optimal and suboptimal LSI polynomials is presented in this note. By an example it is shown that a suboptimal LSI polynomial can be unstable even if the original polynomial does not have any zeros on the unit circle. This has invalidated the proof for modified Shanks’ conjecture in the 2-D case as presented in the paper’ leaving the conjecture to remain ...

It shouldn't have happened, but it did.

Wouldn't have happened to a Limey.

A elderly recluse gentleman was brought to the medical clinic for an assessment. He had pallor, a smooth tongue, a palpable spleen, and petechiae adjacent to hair follicles (left panel). Laboratory work showed a moderate macrocytic anemia and leukopenia and minimal thrombocytopenia. The peripheral smear illustrated a few macroovalocytes and hypersegmented polys. He described no ill health but r...

Mistaken memories: remembering events that never happened.

Our memories can be accurate, but they are not always accurate. Eyewitness testimony, for example, is notoriously unreliable. Insights into both veridical and false remembering have come from recent investigations of memory distortion. Behavioral measures have been used to demonstrate false memory phenomena in the laboratory, and neuroimaging measures have been used to provide clues about the r...
