Administrative procedures are often hailed as the solution to managing an unruly bureaucracy, but they are not self-executing. Rather, they must be implemented by the very agencies whose behavior they are designed to constrain. Further, the expert bureaucrats that oversee these processes have superior insight on how these different procedures tend to play out and can use this information to ste...

This comment on The mouse that trolled by Tania Bubela, Saurabh Vishnubhakat, and Robert Cook-Deegan discusses the authors' description of how patents relating to the gene coding for a protein involved in Alzheimer's disease were obtained and used to sue scientific researchers, of how conflicts can arise among groups of researchers, and of how important research can be delayed or foregone by th...

Through analyzing the data about the releases, comment, and forwarding of 120,000 microblog messages in a year, this paper finds out that the intervals between information releases and comment follow a power law; besides, the analysis of data in each 24 hours reveals obvious differences between microblogging and website visit, email, instant communication, and the use of mobile phone, reflectin...

Our purpose here is to show how it is possible to recover the structure of a randomly permuted concatenated code, and how to use this information for decoding. This result prohibits the use of rst order concatenated codes in public-key cryp-tosystems based on error-correcting codes. R esum e Nous montrons ici comment il est possible de reconstituer la structure d'un code concat en e permut e al...

A recent letter by Maccone presents a solution based on the existing laws of quantum mechanics to the arrow-of-time dilemma. He argues that all phenomena in which the entropy decreases must not leave any information (in the observer's memory) of their having occurred because the observer is a part of the whole system. Maccone concludes that quantum mechanics is necessary to his argument, which ...

This paper studies the problems and threats posed by a type of spam in the blogosphere, called blog comment spam. It explores the challenges introduced by comment spam, generalizing the analysis substantially to any other short text type spam. The authors analyze different high-level features of spam and legitimate comments based on the content of blog postings. The authors use these features t...

this comment is to show that theorem3.3 of dey and chung (1991) (multiparameter estimation intruncated power series distributions under the stein's loss.emph{commun. statist.-theory meth.,} {bf 20}, 309-326) may giveus misleading results. analytically and through simulation, weshow that the theorem does not improve the given estimator.

In the background, it appears that dual guidance is novel for LPB which is not true. Both control group and intervention group used dual guidance. This is a practice followed by most clinicians as plexus is usually not visible on ultrasound imaging. In conclusion, wording "excellent" technical choice is too strong. At best we can describe it as promising as the availability of data regarding th...
