TtOmp85, a β-Barrel Assembly Protein, Functions by Barrel Augmentation

Outer membrane proteins are vital for Gram-negative bacteria and organisms that inherited organelles from them. Proteins from the Omp85/BamA family conduct the insertion of membrane proteins into the outer membrane. We show that an eight-stranded outer membrane β-barrel protein, TtoA, is inserted and folded into liposomes by an Omp85 homologue. Furthermore, we recorded the channel conductance o...

A New Logical Topology Based on Barrel Shifter Network over an All Optical Network

This paper presents a new logical topology SBS-net, a Scalable Barrel Shifter network to be used as a logical topology over an all-optical network using WDM. The major emphasis of the present work is to improve upon the scalability issue. This SBS-net connects any arbitrary numbers of nodes as opposed to the Barrel Shifter, de Bruijn graph and Shufflenet. The average hopping distance between tw...

A patient with a traumatic brain injury due to barrel bomb tertiary blast effect

 Preparing to manage weapons of mass destruction events challenges emergency services systems neighboring Syria every day. Understanding injury from explosives is essential for all providers of emergency care in both civilian and military settings. In this case, the authors present a 22-year-old man who was admitted to the emergency department with displaced skull fracture, epidural hemorrhage ...

Barrel Pseudotilings

This paper describes 4-valent tiling-like structures, called pseudotilings, composed of barrel tiles and apeirogonal pseudotiles in Euclidean 3-space. These (frequently face-to-face) pseudotilings naturally rise in columns above 3-valent plane tilings by convex polygons, such that each column is occupied by stacked congruent barrel tiles or congruent apeirogonal pseudotiles. No physical space i...
