Size segregation of irregular granular materials captured by time-resolved 3D imaging
When opening a box of mixed nuts, a common experience is to find the largest nuts at the top. This well-known effect is the result of size-segregation where differently sized ‘particles’ sort themselves into distinct layers when shaken, vibrated or sheared. Colloquially this is known as the ‘Brazil-nut effect’.

Fairfax seeks to dismiss 400 convictions in cases brought by one officer
Fairfax County prosecutors are moving to throw out more than 400 criminal convictions based on the testimony or work of a former patrol officer who is accused of stealing drugs from the police property room, planting drugs on innocent people and stopping motorists without legal basis, court filings show. In a hearing Friday, a Fairfax judge said he was inclined to vacate felony drug and gun convictions against a former D.C. firefighter and order him released from prison next week after serving nearly two years because of the actions of former officer Jonathan A. Freitag.
Fairfax police said they began investigating Freitag after receiving a tip about him in July 2019. The police department took him off the streets. Freitag, now 25, resigned in May 2020 after the FBI had joined Fairfax County in a criminal investigation of him. But even after The Washington Post first reported the allegations against Freitag in June 2020, he was hired by the Brevard County Sheriff’s Office in Florida in August 2020. The Fairfax human resources department reported to Brevard that the former officer had never been “subject to disciplinary action” and “there are no disciplinary records in his file.”
Freitag was fired by the Brevard County sheriff on April 1 after The Post inquired about his status there. Brevard Sheriff Wayne Ivey then sent a scathing two-page letter to interim Fairfax police chief David M. Rohrer accusing Fairfax of providing “misleading representations to our legitimate efforts to investigate” Freitag. Ivey said it was “outrageous that an individual such as Mr. Freitag, with a history of alleged misconduct at the Fairfax County Police Department, had become a member of our agency and placed in a position that may have negatively impacted our citizens due to your agency’s misrepresentations.”
