Micrographia is a common symptom in Parkinson’s disease, which manifests as either a consistent or progressive reduction in the size of handwriting or both. Neural correlates underlying micrographia remain unclear. We used functional magnetic resonance imaging to investigate micrographia-related neural activity and connectivity modulations. In addition, the effect of attention and dopaminergic ...

Meteor-scatter communication was first described in the pages of QST in 1953 as a means for communicating on dead 15 and 20 m bands. Hams soon realized that even more impressive results could be obtained at 6 and 2 m, where background noise levels are much lower and useful low-elevation gain is obtainable with relatively modest antennas. Early meteor-scatter (MS) contacts used CW and relied on ...
Complement 9 deficiency is the most common complement deficiency in Japan, but it is rare in western countries. Because of Korea’s geographical proximity to Japan, C9 deficiency in Korea has also been assumed to be common although this has never before been proven. We investigated complement deficiency in the serum samples of 6,159 Korean hospital outpatients. The deficiency was screened by a s...
Protein tyrosine phosphorylation is a key regulatory modification in metazoans, and the corresponding kinase enzymes have diversified dramatically. This diversification is correlated with a genome-wide reduction in protein tyrosine content, and it was recently suggested that this reduction was driven by selection to avoid promiscuous phosphorylation that might be deleterious. We tested three pr...
For one-sided matching problems, two widely studied mechanisms are the Random Serial Dictatorship (RSD) and the Probabilistic Serial Rule (PS). The induced outcomes of these two mechanisms are often incomparable and thus there are challenges when it comes to deciding which mechanism to adopt in practice. Working in the space of general preferences, we provide empirical results on the (in)compar...
