On BC-trees and BC-subtrees
A BC-tree (block-cutpoint-tree) is a tree (with at least two vertices) where the distance between any two leaves is even. Motivated from the study of the “core” of a graph, BC-trees provide an interesting class of trees. We consider questions related to BC-trees as an effort to make modest progress towards the understanding of this concept. Constructive algorithms are provided for BC-trees with...
متن کاملSymmetric Two-User MIMO BC and IC with Evolving Feedback
Extending recent findings on the two-user MISO broadcast channel (BC) with imperfect and delayed channel state information at the transmitter (CSIT), the work here explores the performance of the two user MIMO BC and the two user MIMO interference channel (MIMO IC), in the presence of feedback with evolving quality and timeliness. Under standard assumptions, and in the presence of M antennas pe...
متن کاملDisk diffusion and MIC quality control ranges for BC-3205 and BC-3781, two novel pleuromutilin antibiotics.
MIC and disk diffusion quality control (QC) ranges were established for two new pleuromutilin antimicrobials (BC-3205 and BC-3781) in an eight-laboratory study performed according to Clinical and Laboratory Standards Institute M23-A3 guidelines. Staphylococcus aureus ATCC 29213 and 25923, Streptococcus pneumoniae ATCC 49619, and Haemophilus influenzae ATCC 4927 strains were evaluated. The propo...
متن کاملThe transition period for a dairy cow is from two to three weeks prepartum until two to three weeks postpartum
The transition period for a dairy cow is from 3 to 2 wk prepartum until 2 to 3 wk postpartum. The term transition is to underscore the important physiological, metabolic, and nutritional changes occurring in this time frame. It constitutes a turning point in the productive cycle of the cow from one lactation to the next. The manner in which these changes occur and how they are managed are of gr...
متن کاملPretracheal Abscess Following Two Weeks of Endotracheal Intubation
Pretracheal abscess due to endotracheal intubation has not been reported in literature. We present a case of a female patient who was admitted with acute hypercapnic respiratory failure. Patient was initially managed with noninvasive ventilation but eventually was intubated after sustaining a cardiac arrest. She could not be extubated because of poor weaning parameters, so a tracheostomy was pl...
