Podophage Percy infects Caulobacter crescentus, a Gram-negative bacterium that divides asymmetrically and is a commonly used model organism to study the cell cycle, asymmetric cell division, and cell differentiation. Here, we announce the sequence and annotated complete genome of the phiKMV-like podophage Percy and note its prominent features.

We consider a supplier who must predict future orders using forecasts provided by their customers. Our goal is to improve the supplier’s operations through a better understanding of the customers’s forecast behavior. Unfortunately, customer forecasts cannot be used directly. They may be biased since the customer may want to mislead the supplier into believing that orders may be larger than expe...

Stem cells can self-renew and generate differentiating daughter cells. It is not known whether these cells maintain their epigenetic information during asymmetric division. Using a dual-color method to differentially label "old" versus "new" histones in Drosophila male germline stem cells (GSCs), we show that preexisting canonical H3, but not variant H3.3, histones are selectively segregated to...

Recent work on pattern formation in Caenorhabditis elegans has uncovered a new mechanism of asymmetric cell division: the cytoplasm is polarized by cortical proteins, and this polarization then influences the stability of other maternally expressed proteins that in turn determine early embryonic cell fates.

This document defines a Management Information Base (MIB) module for use with network management protocols in the Internet community. In particular, it describes objects used for managing parameters of the "Very High Speed Digital Subscriber Line 2 (VDSL2)" interface type, which are also applicable for managing Asymmetric Digital Subscriber Line (ADSL), ADSL2, and ADSL2+ interfaces.

Three recent studies show that centrosome asymmetry correlates with self-renewal of Drosophila neural and germline stem cells and that equalizing centrosomes disrupts asymmetric cell division.

Materials with ultrafine-grained structure and unique physical and mechanical properties can be obtained by methods of severe plastic deformation, which include processes of asymmetric rolling (AR). Asymmetric rolling is a very effective way to create ultrafine-grained structures of metals and alloys. Since the asymmetric rolling is a continuous process, it has great potential for industrial pr...

During asymmetric cell division, the Notch regulator Numb segregates unequally to establish different cell fates in the two daughter cells. Numb is thought to act as an endocytic protein. Two new studies show that Numb antagonizes Notch signaling by also regulating recycling of Sanpodo-Notch complexes via AP-1.

Crying is a common, normal occurrence in a healthy infant. However, crying is one of the primary reasons parents seek health care for their infant child (Barr, 199 Many parents find inconsolable crying to be particularly difficult because the use of soothing techniques to comfort the infant seems futile. Parents also may view infant crying as a negative reflection on their ability to parent, in...

THE fact that pneumonia mortality is higher in urban areas suggests that air pollution has some effect upon the incidence of this disease. To test such a possibility, pneumonia mortality-rates were calculated for the whole populations of fifty-three cotinty and Metropolitan boroughs in England, Scotland, and Wales, from the Registrar General's annual statistical reviews for the 5-year period 19...
